TO THE STOCKHOLDERS OF NETWORK PERIPHERALS INC. AND FALCONSTOR, INC.

A MERGER PROPOSAL--YOUR VOTE IS VERY IMPORTANT!

Network Peripherals Inc. ("NPI") and FalconStor, Inc. ("FalconStor") have
entered into a merger agreement. In the merger, holders of FalconStor capital
stock will receive shares of NPI common stock in exchange for the shares of
FalconStor capital stock they own. Upon completion of the merger, the former
stockholders of FalconStor capital stock will own more than a majority of the
combined company's outstanding common stock, and the name of the combined
company will be changed to FalconStor Software, Inc. NPI common stock is listed
on The Nasdaq National Market under the trading symbol "NPIX," and the NPI
common stock closed at $ per share on May , 2001. After completion of
the merger, the common stock of the combined company will trade under the
symbol " ".

NPI is requesting that its stockholders approve the adoption of the merger
agreement and the approval of the merger. As part of the approval of the
merger, NPI stockholders will approve the issuance of shares of NPI common
stock in the merger, as well as the amendment and restatement of NPI's restated
certificate of incorporation to increase the authorized number of shares of NPI
common stock from 60,000,000 to 100,000,000 and change NPI's name to
"FalconStor Software, Inc." The exact number of shares to be issued in the
merger is calculated pursuant to an exchange ratio. The precise exchange ratio
will be determined at the closing of the merger and will depend, in part, on
the amount of cash, cash equivalents and short-term investments of NPI minus
any cash payments due under certain agreements with NPI's management plus
$25,000,000. Assuming that these assets remain at $ , as stated in NPI's
Form 10-Q for the quarter ended March 31, 2001, and that shares of NPI's
common stock remain outstanding, the aggregate number of shares of NPI common
stock to be issued to the FalconStor stockholders in the merger would be .
This number of shares would result in FalconStor stockholders owning % of
NPI's capital stock.

In addition, in the event the merger is not completed, NPI is requesting
that its stockholders (i) elect two Class I Directors to serve for three-year
terms and (ii) ratify the selection of PricewaterhouseCoopers LLP as NPI's
independent accountants.

FalconStor is requesting that its stockholders vote to adopt the merger
agreement and approve the merger with NPI.

QUESTIONS AND ANSWERS ABOUT THE MERGER

Q1: What is the merger transaction?

A: In general terms, the merger transaction involves the merger of Empire
Acquisition Corp., a wholly-owned subsidiary of NPI, into FalconStor, Inc. with
FalconStor as the surviving corporation. Holders of FalconStor common stock
will receive shares of NPI common stock in exchange for the shares of
FalconStor common stock they own, including common stock issued upon conversion
of FalconStor preferred stock immediately prior to the merger. As a result of
the merger, the former stockholders of FalconStor will own more than a majority
of NPI's common stock immediately after the merger. Following the merger,
FalconStor's management will be the management of the combined company. NPI is
evaluating strategic alternatives for its existing hardware business, which may
include selling its NuWave technology and its related inventory and equipment.

Q2: What am I being asked to vote upon?

A: NPI stockholders are being asked to approve the adoption of the merger
agreement and approval of the merger. Approval of the adoption of the merger
agreement will include approval of all transactions contemplated thereby,
including, without limitation:

. the issuance of approximately shares of NPI common stock in
the merger;

. the amendment to NPI's restated certificate of incorporation to increase
the authorized number of shares of common stock to 100,000,000 to allow
for the issuance of the shares of NPI common stock to the current holders
of FalconStor stock and to allow for a sufficient reserve of authorized
shares following the merger and to change NPI's name to FalconStor
Software, Inc.

The amendment to the restated certificate of incorporation will take effect
only if the merger is completed.

In addition, NPI stockholders are being asked to approve two further
proposals in the event the merger is not completed:

. the election of Michael Gardner and James Regel as Class I Directors to
serve for three-year terms; and

. the ratification of the selection of PricewaterhouseCoopers LLP as NPI's
independent accountants.

FalconStor stockholders are being asked to approve the adoption of the
merger agreement and approval of the merger. Approval of the adoption of the
merger agreement will include approval of all transactions contemplated
thereby, including, without limitation, the conversion of all of the
outstanding shares of each series of preferred stock immediately prior to the
merger.

Q3: Why are we proposing the merger?

A: The boards of NPI and FalconStor believe that the combination of NPI and
FalconStor will create a stronger, more fully developed company by providing
substantial financial resources that will enable FalconStor to continue
developing and enhancing its storage networking infrastructure software.

A discussion of additional reasons for the merger appears on pages 37 to 39.

Q4: Why has NPI decided to discontinue its Ethernet switching business?

A: NPI has decided to discontinue its Ethernet switching business because of
the unanimous conclusion of NPI's board of directors that the strategic
repositioning of the company as an emerging leader in storage networking
infrastructure software, with a significant cash position, a public-company
currency, leading-edge technology, a shipping product and a strong, proven
management team was a superior alternative to being in the Ethernet switching
business.

Q5: Why does the merger agreement provide for the amendment of NPI's restated
certificate of incorporation?

A: If the merger is approved, NPI's restated certificate of incorporation will
be amended to increase the authorized number of shares of its common stock
because NPI will be issuing approximately shares of common stock in
connection with the merger. NPI currently has approximately 45,000,000 shares
available for issuance. The increase in the authorized number of shares by
40,000,000 will assure that sufficient shares are available to be issued in
connection with the merger, and that an adequate number of shares of common
stock will be available for future issuances under the combined company's
equity compensation plans, and in the event the combined company's board of
directors determines that it is necessary or appropriate to issue additional
shares in connection with a stock dividend, the raising of additional capital,
the acquisition of other businesses, the establishment of strategic
relationships with corporate partners, or for other corporate purposes.
FalconStor's management is not currently contemplating any of these
transactions, other than issuances pursuant to its or NPI's stock option plans.
The name of the combined company will be changed to FalconStor Software, Inc.
to reflect the combined company's new business focus.

This amendment to NPI's restated certificate of incorporation will take
effect only if the merger is completed.

Q6: What will I receive in the merger?

A: NPI stockholders will not receive any consideration in the merger, and the
number of shares of NPI common stock that they hold will be unaffected.
However, NPI will be issuing approximately shares of common stock to
FalconStor stockholders in connection with the merger, which will have a
dilutive effect on the percentage ownership of each NPI stockholder.

FalconStor stockholders will receive shares of NPI common stock for the
shares of FalconStor common stock they hold. Based on shares of NPI common
stock outstanding on , 2001, shares of NPI common stock will be issued
to FalconStor stockholders. As a result, the holders of FalconStor common stock
will hold approximately % of the outstanding common stock of NPI. However,
the price of NPI common stock fluctuates. Therefore, the closing price as of
any date in the past provides no assurance as to the value of NPI common stock
that FalconStor stockholders will receive upon completion of the merger.

Q7: What restrictions will apply to the shares of NPI common stock that I will
receive in the merger?

A: All shares of NPI common stock received by the officers, directors and
stockholders of FalconStor in the merger will be subject to transfer
restrictions pursuant to lock-up agreements for a period of 365 days following
the effective date of the merger. Following the merger, the board of directors
of the combined company may, in its sole discretion, release any or all of the
shares from the lock-up restrictions.

Q8: On April 2, 2001, NPI purchased 9,792,401 shares of FalconStor Series C
preferred stock for $25,000,000. What effect will NPI's purchase of shares of
Series C preferred stock of FalconStor have on the merger?

A: All shares of FalconStor Series C preferred stock issued to NPI prior to the
merger will be canceled and the proceeds received by FalconStor from that sale
of stock will remain in FalconStor for use in ongoing operations after the
merger.

Q9: What are the tax consequences of the merger?

A: Subject to the discussion in "Tax Consequences" below, NPI and FalconStor
have structured the merger so that, for federal income tax purposes, FalconStor
stockholders will generally not recognize a gain or a loss upon the receipt of
NPI common stock in the merger, except with respect to cash received in lieu of
fractional shares or in connection with the exercise of appraisal rights. NPI
stockholders will not recognize taxable gains or losses as a result of the
merger. NPI and FalconStor have conditioned the merger on receipt of legal
opinions regarding the tax consequences of the merger.

Q10: If I am a holder of FalconStor capital stock, how should I send in my
stock certificates for exchange?

A: Do not send in your stock certificates with your proxy card. You must keep
your stock certificates until after the merger has been completed, after which
you will receive a letter of transmittal describing how you may exchange your
FalconStor stock certificates for certificates representing shares of NPI
common stock. At that time, you will have to submit your FalconStor stock
certificates to the exchange agent with your completed letter of transmittal.

Q11: How does my board of directors recommend that I vote on the proposals?

A: NPI stockholders: The NPI board of directors unanimously recommends that you
vote FOR the proposals submitted by the NPI board.

FalconStor stockholders: The FalconStor board of directors unanimously
recommends that you vote FOR the proposal submitted by the FalconStor board.

Q12: What vote is required to approve the proposals?

A: NPI stockholders: Assuming a quorum is present, each of the proposals
regarding the merger submitted to NPI stockholders will require the affirmative
vote of holders of at least a majority of the shares of NPI common stock
entitled to vote at the NPI annual meeting. If you abstain or do not instruct
your broker how to vote, your abstention or broker non-vote will have the same
effect as a vote against the proposal to approve the merger agreement and the
proposal for the amendment of the restated certificate of incorporation.
Abstentions and broker non-votes will have no effect on the election of
directors. Abstentions will have the same effects as a negative vote on the
ratification of NPI's selection of its independent accountants.

The directors shall be elected by a plurality of votes cast. Ratification of
the selection of NPI's appointment of PricewaterhouseCoopers LLP as its
independent accountants requires a majority of votes cast.

FalconStor stockholders: Assuming a quorum is present, the proposal requires
the affirmative vote of holders of at least a majority of the outstanding
voting power of the common stock and the preferred stock voting together as a
single class, and a majority of the outstanding shares of Series A preferred
stock, two-thirds of the outstanding shares of Series B preferred stock, and a
majority of the outstanding shares of Series C preferred stock, each series
voting separately. If you abstain or do not vote, your abstention or non-vote
will have the same effect as a vote against the merger proposal.

Q13: What do I need to do now?

A: After you read and consider the information in this document, mail your
signed proxy card in the enclosed return envelope as soon as possible, so that
your shares may be represented at the appropriate stockholders' meeting. You
should return your proxy card whether or not you plan to attend your
stockholders' meetings. If you attend your stockholders' meeting, you may
revoke your proxy at any time before it is voted and vote in person if you
wish.

Q14: What do I do if I want to change my vote after I have sent in my proxy
card?

A: You can change your vote at any time before your proxy is voted at the
appropriate stockholders' meeting. You can do this in one of three ways. First,
you can send a written notice stating that you would like to revoke your proxy.
Second, you can complete and submit a new proxy card at a later date. If you
choose either of these methods, you must submit your notice of revocation or
your new proxy card to NPI or FalconStor, as the case may be, before your
stockholders' meeting. Finally, you can attend your stockholders' meeting and
vote in person. Simply attending your stockholders' meeting, however, will not
revoke your proxy. If you have instructed a broker to vote your shares, you
must follow directions received from your broker to change your vote.

Q15: If my shares of NPI common stock are held in "street name" by my broker,
will my broker vote my shares for me?

A: Your broker will vote your shares only if you provide instructions on how to
vote. If you do not provide your broker with instructions on how to vote, your
broker's non-votes will have the same effect as votes against approval of the
merger. You should follow the directions provided by your broker regarding how
to instruct your broker to vote your shares. Abstentions and broker non-votes
will have no effect on the election of directors. Abstentions will have the
same effects as a negative vote on the ratification of NPI's selection of its
independent accountants.

Q16: What constitutes a quorum at the stockholders' meetings?

A: A quorum is a majority of the outstanding shares entitled to vote which are
present or represented by proxy at the stockholders' meetings. A quorum must
exist for the transaction of business at the stockholders' meetings. If you
submit a properly executed proxy card, even if you abstain from voting, your
shares will be considered part of the quorum. Broker non-votes, which are
shares held by a broker or nominee that are represented at the stockholders'
meeting, but with respect to which the broker or nominee is not empowered to
vote on a proposal, are also included in determining the presence of a quorum.

Q17: Who can I call with questions?

A: If you have any questions about the merger or how to submit your proxy, or
if you need additional copies of this joint proxy statement/prospectus or the
enclosed proxy card or voting instructions, you should contact the individuals
listed below:

SUMMARY OF THE JOINT PROXY STATEMENT/PROSPECTUS

This summary highlights selected information from this document and may not
contain all of the information that is important to you. Even though we have
highlighted what we believe is the most important information, we encourage you
to read the entire joint proxy statement/prospectus for a complete
understanding of the proposed merger of a wholly-owned subsidiary of NPI into
FalconStor. You should also review the other available information referred to
in "Where You Can Find More Information" on page 146.

The Companies

Network Peripherals Inc.

Until recently, NPI designed and sold Ethernet switching solutions designed
for local area networks, or LANs. In response to unfavorable market conditions
and in order to take best advantage of the opportunity presented by
FalconStor's technology and market opportunity, NPI is evaluating strategic
alternatives for its existing hardware business, which may include selling its
NuWave technology and its related inventory and equipment.

NPI's principal executive offices are located at 2859 Bayview Drive,
Fremont, California 94538. NPI's telephone number is (510) 897-5000.

FalconStor, Inc.

FalconStor is a provider of storage networking infrastructure software.

FalconStor's principal executive offices are located at 125 Baylis Road,
Suite 140, Melville, New York 11747. FalconStor's telephone number is (631)
777-5188.

Risk Factors

The "Risk Factors" beginning on page 16 should be considered carefully by
both NPI and FalconStor stockholders in evaluating whether to approve the
adoption of the merger agreement and approval of the merger. These risk factors
should be considered along with any additional risk factors in documents
incorporated by reference in this joint proxy statement/prospectus and any
other information included or incorporated by reference herein, including in
conjunction with forward-looking statements made herein.

Reasons for the Merger (page 37)

The NPI and the FalconStor boards approved the merger based on a number of
factors, including, among other things, their belief that the combination of
NPI and FalconStor will create a stronger, more successful company, with
enhanced prospects for continued viability, by:

. establishing the merged company as a publicly-listed, well-capitalized
emerging leader in storage networking infrastructure software; and

. providing the stockholders of both companies with the potential for more
financial success than either company has on its own.

The two boards of directors also considered separate reasons for the merger
as well as various risks associated with the merger.

The Structure of the Merger (page 47)

Merger. At the closing of the merger, a wholly-owned subsidiary of NPI will
merge into FalconStor and FalconStor will be the surviving corporation.
Immediately prior to the merger, each share of FalconStor preferred stock shall
be converted into that number of shares of common stock for which each share of
preferred stock is then convertible. Each share of FalconStor common stock then
will be converted into the right to receive shares of NPI common stock.

The Merger Agreement

The merger agreement is attached as Annex A to this joint proxy
statement/prospectus. We encourage you to read the merger agreement, as it is
the legal document that governs the merger.

Conversion of Securities; Adjustment of Exchange Ratio (page 57). In the
merger, each share of FalconStor common stock will be converted into the right
to receive shares of NPI common stock. Immediately prior to the effective time
of the merger, all shares of FalconStor preferred stock will

be converted into shares of FalconStor common stock at the then applicable
conversion price. The number of shares of NPI common stock that each FalconStor
stockholder will receive will be determined by an exchange ratio set forth in
more detail beginning on page 58. The precise exchange ratio will be determined
at the closing of the merger and will depend, in part, on the amount of cash,
cash equivalents and short-term investments of NPI minus any cash payments due
under certain agreements with NPI's management plus $25,000,000. This figure
will be calculated as of the end of the calendar month prior to the effective
time of the merger without giving effect to expenses NPI incurs in connection
with the merger. To the extent this amount is less than $90,000,000, the number
of merger shares shall be increased by an equivalent percentage.

NPI Common Stock (page 55). The NPI common stock that holders of FalconStor
common stock will receive as a result of the merger is traded and quoted on The
Nasdaq National Market under the market symbol, "NPIX." Following the
completion of the merger, the name of the company will be changed to FalconStor
Software, Inc. and the common stock of the combined company will trade under
the symbol " ."

Treatment of Options (page 46). All outstanding options to purchase
FalconStor common stock will be assumed by NPI. Each option shall remain
subject to the same terms and conditions set forth in FalconStor's stock option
plan. Such options will be exercisable for the number of shares of NPI common
stock that is equal to the number of shares of FalconStor common stock subject
to the option immediately prior to the merger multiplied by the exchange ratio.
The exercise price of the assumed options will be correspondingly adjusted by
dividing it by the exchange ratio.

Conditions to the Merger (page 64). The completion of the merger depends
upon the satisfaction of a number of conditions, including:

. approval of the merger agreement and the transactions it contemplates by
the stockholders of NPI and FalconStor;

. the receipt of clearance for the merger under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976;

. approval for quotation on The Nasdaq National Stock Market of the shares
of NPI common stock to be issued in the merger;

. NPI's maintenance of at least $55,000,000 of cash, cash equivalents and
short-term investments exclusive of estimated cash payments due under
retention agreements with certain members of NPI's management as a result
of the merger and $25,000,000 of Series C preferred stock of FalconStor
owned by NPI; and

. receipt by each of NPI and FalconStor of an opinion of counsel to the
effect that the merger will be treated as a tax-free reorganization under
the Internal Revenue Code of 1986.

No Solicitation (page 61). Subject to certain exceptions, neither NPI nor
FalconStor may solicit or support any proposal for a merger or similar
transaction involving any third party, participate in negotiations or
discussions concerning any proposed acquisition by a third party, provide any
non-public information to any third party relating to any proposed acquisition,
or approve or recommend any proposed acquisition by a third party. Prior to the
effective time of the merger, however, NPI has the right to sell its assets
related directly to its Ethernet switching business.

Termination (page 65). Subject to certain exceptions, either NPI or
FalconStor can terminate the merger agreement if the merger is not completed by
September 30, 2001, and in various other circumstances.

Termination Fees and Expenses (page 65). In general, all fees and expenses
incurred in connection with the merger agreement and the transactions it
contemplates shall be paid by the party incurring such expenses, whether or not
the merger is completed.

NPI and FalconStor have agreed that if the merger agreement is terminated by
NPI or FalconStor and the termination is not a result of any breach by
FalconStor, NPI will pay FalconStor $3,000,000.

Treatment of NPI Stock Options and Restricted Stock (page 46)

NPI's equity plans include its 1993, 1996, 1997 and 1999 Stock Plans and its
1994 Outside Directors Stock Option Plan, each as amended. The merger
constitutes a "change of control" or "transfer of control" of NPI under its
employee stock plans. The following is a description of the effect of the
merger on those plans.

. All options held by employees, directors or consultants under the various
stock option plans will remain outstanding and the vesting of certain
options will accelerate as a result of the transfer of control. See
"Interests of Certain NPI Persons in the Merger."

. The 1994 Outside Directors Stock Option Plan provides that, in the event
of a transfer of control, any unexercisable or unvested portion of the
outstanding options shall be immediately exercisable and vested in full
as of the date 10 days prior to the date of the transfer of control.

Treatment of FalconStor Stock Options and Restricted Stock (page 46)

All outstanding FalconStor options shall remain subject to the terms and
conditions of the existing FalconStor stock option plan, including any
restrictions on the exercisability of each option and the term, exercisability
and vesting schedule, except that:

. each option will be exercisable for that number of shares of NPI common
stock equal to the product of the number of shares of FalconStor common
stock that would be issuable upon exercise of the option immediately
prior to the effective time of the merger multiplied by the exchange
ratio;

. the per share exercise price for the shares of NPI common stock issuable
upon exercise of each option will be equal to the quotient determined by
dividing the exercise price per share of FalconStor common stock at which
the option is exercisable immediately prior to the effective time of the
merger by the exchange ratio; and

. further adjustments may be made in the case of incentive stock options,
if required under U.S. federal tax laws.

Under the terms of the merger agreement, NPI has agreed to assume all
FalconStor options, whether vested or unvested.

Interests of Certain Persons in the Merger (page 45)

Interests of Certain NPI Persons in the Merger

In addition, certain officers have offer letters, salary continuation
agreements, separation and release agreements or employment agreements pursuant
to which the merger constitutes a change of control and according to which,
upon the closing of the merger, a specified percentage of the executive
officers' stock options will become 100% vested. In addition, if the combined
company terminates the employment of any of these executive officers, pursuant
to the terms of their respective agreements, following the closing of the
merger such officers are entitled to a combination of severance pay and
benefits.

On October 18, 2000, Glenn Penisten, chairman of the board of directors of
NPI and an NPI employee, purchased 17,500 shares of FalconStor Series B
preferred stock at a purchase price of $25,000.

As a result of these interests, the officers and directors of NPI who are
parties to these agreements or who own stock of FalconStor may be more likely
to vote to approve the merger agreement than if they did not hold these
interests. NPI's stockholders should consider whether these interests may have
influenced these directors and officers to support or recommend the merger.

Interests of Certain FalconStor Persons in the Merger

Under the merger agreement, NPI has agreed to honor any indemnification
provisions of FalconStor's certificate of incorporation and bylaws for a period
of six years from the completion of the merger. NPI has also agreed to provide
for indemnification provisions in the certificate of incorporation and bylaws
of the surviving corporation of the merger. In addition, NPI has agreed to
provide director and officer liability insurance for any claims arising in
connection with the merger agreement for a period of not less than six years
following the completion of the merger.

The chairman of the board of directors of FalconStor is a member of a
"group," as defined by the Securities Exchange Act of 1934, that is the largest
beneficial owner of NPI common stock.

As a result of these interests, the directors and officers of FalconStor may
be more likely to vote to approve the merger agreement than if they did not
hold these interests. FalconStor stockholders should consider whether these
interests may have influenced these directors and officers to support or
recommend the merger.

Board Composition (page 46)

Upon the closing of the merger:

. NPI's board of directors will have four directors with one vacancy;

. four existing directors, James Regel, Thomas Brown, Michael Gardner and
Charles Hart, will resign; and

. Barry Rubenstein, ReiJane Huai and Irwin Lieber will be appointed to the
NPI board.

At the closing, the NPI board will be Glenn Penisten, Barry Rubenstein,
ReiJane Huai and Irwin Lieber. The term of Irwin Lieber shall expire at the
annual meeting of stockholders to be held in 2002. The terms of Barry
Rubenstein and Glenn Penisten shall expire at the annual meeting of
stockholders to be held in 2003, and the term of ReiJane Huai shall expire at
the annual meeting of stockholders to be held in 2004.

Relative Percentages of Ownership

The final exchange ratio shall be determined using the number of shares
outstanding of NPI and FalconStor two days prior to the date of the
stockholders' meetings. Consequently, the exact percentage ownership
immediately following the merger cannot be determined as of the date of this
joint proxy statement/prospectus. Based on the number of shares outstanding for
each of NPI and FalconStor on , 2001, immediately after the closing of the
merger, the holders of FalconStor common stock would hold approximately %
of the outstanding common stock of NPI. The holders of NPI common stock would
hold approximately % of the outstanding NPI common stock immediately after
the closing.

Fairness Opinion of NPI's Financial Advisor

Opinion of NPI's Financial Advisor (pages 41 through 45). In deciding to
approve the merger, the NPI board of directors considered the opinion of its
financial advisor, Lehman Brothers Inc., that, as of the date of its opinion
and subject to the considerations and limitations set forth in its opinion, the
aggregate consideration to be paid by NPI in the merger is fair, from a
financial point of view to NPI and its stockholders. The full text of this
opinion is attached as Annex B to this joint proxy statement/prospectus. NPI
urges its stockholders to read the opinion of Lehman Brothers carefully and in
its entirety.

Recommendations of the Boards of Directors

NPI stockholders (page 40): The NPI board of directors believes that the
proposed merger is fair to, advisable for, and in the best interest of NPI and
its stockholders, has unanimously voted to approve the terms and provisions of
the merger agreement, and unanimously recommends that you vote FOR the adoption
of the merger agreement and approval of the merger, including all transactions
contemplated thereby.

FalconStor stockholders (page 40): The FalconStor board of directors
believes that the merger is fair to, advisable for, and in the best interest of
FalconStor and its stockholders, has unanimously voted to approve the merger
agreement, and unanimously recommends that you vote FOR the adoption of the
merger agreement and approval of the merger, including all transactions
contemplated thereby.

Stockholder Approvals

NPI stockholders (page 28): For NPI, the affirmative vote of at least a
majority of the shares of NPI common stock entitled to vote at the annual
meeting of stockholders is required for approval of the adoption of the merger
agreement and the approval of the merger. If you abstain or do not vote, your
abstention or non-vote will have the same effect as a vote against the merger
proposal. As of the record date, NPI directors and officers beneficially owned
in the aggregate approximately % of the outstanding shares. Pursuant to
voting agreements, each NPI officer and director has agreed to vote all of his
shares in favor of the merger proposal.

FalconStor stockholders (page 30): For FalconStor, the proposal requires the
affirmative vote of holders of at least a majority of the outstanding voting
power of the common stock and the preferred stock voting together as a single
class, and a majority of the outstanding shares of Series A preferred stock,
two-thirds of the outstanding shares of Series B preferred stock, and a
majority of the outstanding shares of Series C preferred stock, each series
voting separately. If you abstain or do not vote, your abstention or non-vote
will have the same effect as a vote against the merger proposal. As of the
record date, the directors and executive officers of FalconStor beneficially
owned in the aggregate approximately % of the outstanding voting power of
FalconStor stock. Pursuant to voting agreements, each FalconStor officer,
director and certain other FalconStor stockholders have agreed to vote all of
the shares beneficially owned by them in favor of the adoption of the merger
agreement and approval of the merger. The stockholders who have delivered
voting agreements control a sufficient number of shares to approve the merger.

The Stockholders' Meetings (pages 27 and 30)

The annual meeting of the stockholders of NPI will be held on ,
, 2001, at a.m., local time, at the Marriott Hotel, 46100
Landing Parkway, Fremont, California.

The special meeting of the stockholders of FalconStor will simultaneously be
held on , , 2001, at p.m., local time, at the
offices of FalconStor, 125 Baylis Road, Suite 140, Melville, New York 11747.

Tax Consequences (page 47)

NPI

The parties have structured the merger so that neither NPI nor its
stockholders will recognize gain or loss for U.S. federal income tax purposes
in connection with the merger.

FalconStor

The parties have structured the merger so that neither FalconStor nor its
stockholders will recognize gain or loss for U.S. federal income tax purposes
in connection with the merger.

Accounting Treatment (page 48)

The business combination will be accounted for under the purchase method of
accounting. Although NPI will be acquiring FalconStor, after the transaction,
FalconStor stockholders will hold a majority of the voting interests in the
combined enterprise. Accordingly, for accounting purposes, the acquisition will
be a "reverse acquisition" and FalconStor will be the "accounting acquiror." As
FalconStor will be the accounting acquiror, its accounts will be recorded at
historical cost and the assets and liabilities of NPI will be recorded at their
estimated fair value as of the closing date.

Regulatory Approvals (page 55)

The merger is subject to the provisions of the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, or the HSR Act.

Appraisal Rights (page 31)

Under Delaware law, the holders of common stock (including the common stock
issued upon conversion of FalconStor preferred stock immediately prior to the
merger) of FalconStor will have appraisal rights and may be entitled to receive
cash equal to the fair market value of their FalconStor common stock. To do so,
they must follow the procedures set forth under Section 262 of the Delaware
General Corporation Law. Section 262 is attached as Annex C to this joint proxy
statement/prospectus.

SELECTED UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION
(In thousands, except per share data)

The selected unaudited pro forma condensed combined financial data set forth
below gives effect to FalconStor's proposed acquisition of NPI as if the
acquisitions had been completed on January 1, 2000 for statement of operations
purposes, and as of March 31, 2001 for balance sheet purposes, and is derived
from the unaudited pro forma condensed combined financial statements included
elsewhere in this joint proxy statement/prospectus. This pro forma financial
information should be read in conjunction with the unaudited pro forma
condensed combined financial statements and related notes, which are included
elsewhere in this joint proxy statement/prospectus, and the separate historical
financial statements and related notes of FalconStor and NPI which are also
included in this joint proxy statement/prospectus.

The pro forma financial information includes adjustments, which are based
upon preliminary estimates, to reflect the allocation of the purchase
consideration to the acquired assets and liabilities of NPI. The final
allocation of the purchase consideration will be determined after the
completion of the merger and will be based on appraisals and comprehensive
final evaluation of the fair value of NPI's tangible assets acquired,
liabilities assumed, identifiable intangible assets and goodwill at the time of
the merger. The final determination of tangible and intangible assets may
result in depreciation and amortization expense that is different than the
preliminary estimates of these amounts.

The selected unaudited pro forma condensed combined financial information is
presented for illustrative purposes only and does not purport to represent what
the actual consolidated results of operation or the consolidated financial
position of FalconStor would have been had the merger occurred on the dates
assumed, nor are they necessarily indicative of future consolidated results of
operations or financial position.

the development and growth of the business, and therefore do not anticipate
paying any cash dividends in the foreseeable future.

RISK FACTORS

You should carefully consider the risks described below regarding the
merger, together with all of the other information included in this joint proxy
statement/prospectus, before making a decision about voting on the proposals
submitted for your consideration.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

Some of the information in this joint proxy statement/prospectus and in the
documents that are incorporated herein by reference, including the risk factors
in this section, contains forward-looking statements that involve risks and
uncertainties. These statements relate to, among other things, consummation of
the merger, future financial and operating results of the combined company and
benefits of the pending merger. In many cases, you can identify forward-looking
statements by terminology such as "may," "will," "should," "expects," "plans,"
"anticipates," "believes," "estimates," "predicts," "potential," or "continue,"
or the negative of these terms and other comparable terminology. These
statements are only predictions. Actual results could differ materially from
those anticipated in these forward-looking statements as a result of a number
of factors, including the risks factors described below, elsewhere in this
joint proxy statement/prospectus and in NPI's periodic filings with the
Securities and Exchange Commission, or SEC, incorporated herein by reference.
NPI is not under any obligation (and expressly disclaims any such obligation)
to update or alter its forward-looking statements, whether as a result of new
information, future events or otherwise. Before making a decision regarding the
merger, you should be aware that the occurrence of the events described in
these risk factors could harm NPI's business, operating results, and financial
condition.

Risks Related To The Merger

The merger will result in substantial dilution of the ownership interests of
current NPI stockholders.

Upon completion of the merger, each share of FalconStor common stock will be
exchanged for approximately shares of NPI common stock. As a result, the
current stockholders of NPI will own approximately 33% of the outstanding
common stock of the combined company. This represents substantial dilution of
the ownership interests of the current NPI stockholders. However, the number of
shares of NPI common stock that each FalconStor stockholder will receive will
be determined by an exchange ratio. The precise exchange ratio will be
determined at the closing of the merger and will depend, in part, on the amount
of cash, cash equivalents and short-term investments of NPI minus any cash
payments due under certain agreements with NPI's management plus $25,000,000.
This figure will be calculated as of the end of the calendar month prior to the
effective time of the merger without giving effect to expenses NPI incurs in
connection with the merger. To the extent this amount is less than $90,000,000,
the number of merger shares shall be increased by an equivalent percentage. Any
adjustment to the calculation of the exchange ratio will cause further dilution
to NPI stockholders.

The volatility of the market price of NPI common stock may reduce the value of
the NPI shares received in the merger by FalconStor stockholders.

The market price of NPI common stock is by nature subject to the general
price fluctuations in the market for publicly traded equity securities, and has
experienced significant volatility. This fluctuation is, or in the future may
be, caused by many factors including:

. quarterly fluctuations in operating results;

. announcements of new products by the combined company or its competitors;

. gains or losses of significant customers;

. changes in stock market analysts' estimates;

. the presence or absence of short-selling of its common stock; and

. events affecting other companies that the market deems comparable to the
combined company.

Accordingly, you should obtain recent market quotations for NPI common
stock in order to assess the market value of the NPI shares that will be
issued in exchange for the FalconStor shares.

NPI cannot predict or assure FalconStor stockholders as to the market price
of NPI common stock before the closing of the merger. If the market price of
NPI common stock declines prior to the closing of the merger, the value of the
NPI common stock to be received by holders of FalconStor common stock in the
merger will be reduced.

Failure of the merger to achieve potential benefits could harm the business
and operating results of the combined company.

NPI and FalconStor expect that the combination of NPI and FalconStor will
result in potential benefits for the combined company. Achieving these
potential benefits will depend on a number of factors, some of which include:

. retention of key management, marketing and technical personnel after the
merger;

. the ability of the combined company to increase its customer base and to
increase the sales of FalconStor products; and

. competitive conditions in the storage networking infrastructure software
market.

Neither NPI nor FalconStor can assure you that the anticipated benefits
will be achieved. The failure to achieve anticipated benefits could harm the
business, financial condition and operating results of the combined company.

The combined company's reported financial results will suffer as a result of
purchase accounting treatment and the impact of amortization of goodwill and
other intangibles relating to the merger.

The business combination will be accounted for under the purchase method of
accounting. Although NPI will be acquiring FalconStor, after the transaction,
FalconStor stockholders will hold a majority of the voting interests in the
combined company. Accordingly, for accounting purposes, the acquisition will
be a "reverse acquisition" and FalconStor will be the "accounting acquiror."
As FalconStor will be the accounting acquiror, its accounts will be recorded
at historical cost and the assets and liabilities of NPI will be recorded at
their estimated fair value as of the closing date.

As described in the Unaudited Pro Forma Condensed Combined Financial
Statements, intangible assets of approximately $23,500,000 are expected to be
recorded with respect to the business combination and will be amortized over a
period of three years following the closing of the business combination;
however, because the number of shares to be exchanged in the business
combination is subject to change based on an exchange ratio formula, the final
determination of the purchase price will not occur until the closing of the
merger, and will be based upon the fair market value of NPI's stock on that
date. The amount of the purchase price allocated to intangible assets,
including goodwill, may fluctuate significantly as a result.

If goodwill and other intangible assets were amortized in equal quarterly
amounts over three years following completion of the merger, the accounting
charge attributable to these items would be approximately $2,000,000 per
fiscal quarter or $7,800,000 per fiscal year.

The financial results of the combined company could suffer as a result of the
costs of the merger.

NPI and FalconStor expect to incur one-time and other charges, including
direct transaction expenses, of between $ and $ in connection
with the merger. FalconStor is expected to allocate the costs it incurs to
FalconStor. If the benefits of the merger do not exceed the costs associated
with the merger, including any dilution to NPI stockholders resulting from the
issuance of shares of NPI common stock in the merger, the combined company's
financial results, including earnings per share, could suffer, and the market
price of the combined company's common stock could decline.

The rights of holders of FalconStor common stock will change as a result of
the merger.

Following the merger, holders of FalconStor common and preferred stock
outstanding immediately prior to the merger will become holders of NPI common
stock. There are differences between the rights of NPI stockholders under NPI's
restated certificate of incorporation and bylaws and the rights of FalconStor
stockholders under FalconStor's certificate of incorporation and bylaws. As a
result of these differences, the holders of FalconStor common and preferred
stock may have less control over corporate actions proposed to be taken by NPI
than those holders had over corporate actions proposed to be taken by
FalconStor. The following is a description of some of these differences:

. NPI's certificate of incorporation provides for a classified board of
directors where only a portion of all of the members of the board of
directors are elected at each annual meeting of stockholders;

. NPI's certificate of incorporation provides that the holders of at least
two-thirds of the shares of NPI common stock must approve changes to some
of the provisions contained in NPI's certificate of incorporation;

. NPI's bylaws may only be amended with the approval of a majority of the
total number of authorized directors or the approval of the holders of at
least two-thirds of the shares of NPI common stock;

. NPI's certificate of incorporation does not permit holders of NPI common
stock to cumulate their votes in electing members of NPI's board of
directors;

. The holders of NPI common stock may not approve any action by written
consent; all actions must be approved at a stockholder meeting.

For more information, see "Comparison of Rights of Holders of NPI Common
Stock and FalconStor Common Stock," beginning on page 68.

Officers and directors of FalconStor will receive benefits that may have
influenced them to support or approve the merger.

Some of the directors and officers of FalconStor have continuing
indemnification against liabilities that give them interests in the merger that
are different from the interests of the stockholders of FalconStor, including
the following:

. NPI has agreed to honor any indemnification provision of FalconStor's
certificate of incorporation, as amended, and bylaws for a period of six
years from the completion of the merger;

. NPI and FalconStor have agreed that Barry Rubenstein, ReiJane Huai and
Irwin Lieber, who currently serve on the board of FalconStor, will be
appointed to serve on the combined company's board of directors following
the merger.

For the above reasons, the directors and officers of FalconStor could be
more likely to vote to approve the terms of the merger than if they did not
have these interests. FalconStor stockholders should consider whether these
interests may have influenced these directors and officers to support or
recommend the merger. See "Interest of Certain FalconStor Persons in the
Merger," beginning on page 45.

Officers of NPI have certain conflicts of interest that may influence them to
support or approve the merger.

Some officers of NPI participate in arrangements that give them interests
in the merger that are different from the interests of the stockholders of
NPI. Certain NPI officers will receive payments in connection with the merger.
In addition, certain officers of NPI are entitled to severance benefits if
they are terminated by NPI as a result of the merger. Furthermore, Glenn
Penisten, the chairman of the board and an employee of NPI, owns 17,500 shares
of FalconStor's Series B preferred stock. For the foregoing reasons, some of
the officers of NPI could be more likely to vote to approve the terms of the
merger than if they did not have these interests. NPI stockholders should
consider whether these interests may have influenced these officers to support
or recommend the merger. See "Interest of Certain NPI Persons in the Merger,"
on page 45.

If the merger is challenged by governmental authorities, the merger may not
occur or may occur on terms imposed by the governmental authorities, which
terms may not be favorable to the combined company.

Before the merger may be completed, various approvals must be obtained from
or notifications submitted to governmental authorities in the United States.
These governmental entities may attempt to prevent the merger from occurring
or attempt to condition their approval of the merger on the imposition of
certain regulatory conditions that may have the effect of imposing additional
costs on NPI or of limiting the combined company's revenues. The imposition of
regulatory conditions may make it more difficult for FalconStor to continue
developing and enhancing its storage networking infrastructure software.

Failure to complete the merger could cause NPI's stock price to decline and
could harm NPI's and FalconStor's business and operating results.

The merger agreement contains conditions which NPI and/or FalconStor must
meet in order to consummate the merger. In addition, the merger agreement may
be terminated by either NPI or FalconStor under certain circumstances. If the
merger is not completed for any reason, NPI and FalconStor may be subject to a
number of risks, including the following:

. since NPI has ceased substantially all of its business activities, NPI
will have no revenue on a going forward basis;

. depending on the reasons for termination, NPI may be required to pay
$3,000,000 to FalconStor;

. the market price of NPI common stock may decline to the extent that the
relevant current market price reflects a market assumption that the
merger will be completed;

. many costs related to the merger, such as legal, accounting, financial
advisor and financial printing fees, have to be paid regardless of
whether the merger is completed;

. there may be substantial disruption to the businesses of NPI and
FalconStor and distraction of their workforces and management teams; and

. NPI will hold $25,000,000 worth of unregistered, preferred stock of
FalconStor.

In addition, in response to the announcement of the merger, customers or
suppliers of NPI and/or FalconStor may delay or defer product purchase or
other decisions. Any delay or deferral in product purchase or other decisions
by customers or suppliers could harm the business of the relevant company,
regardless of whether the merger is completed. Similarly, current and
prospective NPI and/or FalconStor employees may experience uncertainty about
their future roles with NPI or FalconStor until the merger is completed. As a
result, the ability of NPI and/or FalconStor to attract and retain key
management, sales, marketing and technical personnel could suffer.

A liquidation of NPI, instead of the proposed merger with FalconStor, might
result in increased returns for NPI's stockholders.

NPI currently has total assets with a book value of approximately
$100,000,000. While NPI's board has determined that it is in the best interests
of NPI and its stockholders to enter into the merger, it is possible that, if
the merger is completed, the holders of NPI common stock immediately prior to
the merger may hold shares of the combined company's common stock worth less
than the dollar amount they would have received if NPI's assets had been
distributed among NPI's stockholders.

Failure to consummate the merger could adversely affect NPI's cash position
and attractiveness to acquirors.

On April 2, 2001, NPI purchased $25,000,000 of FalconStor's Series C
preferred stock. If this merger is not consummated, NPI will hold $25,000,000
of unregistered preferred stock of a privately-held company with limited resale
opportunities. This will reduce its operating cash and may reduce its
attractiveness to potential acquirors.

Tax Risks Related to the Merger

A successful IRS challenge to the tax-free reorganization status of the
merger could result in FalconStor stockholders incurring substantial tax
liability with respect to their FalconStor stock exchanged in the merger.

Risks Related to the Combined Company's Business Following the Merger

In addition to the risk factors related to the merger set forth above, after
the merger, the combined company will be subject to the following risks:

NPI and FalconStor have a history of losses, and the combined company may not
achieve or maintain profitability.

Due to the early stage of FalconStor and its product, FalconStor has limited
visibility into future revenues. FalconStor currently has signed contracts with
resellers and original equipment manufacturers, or OEMs, to begin shipping
products. FalconStor's business model depends upon signing additional OEM
customers, developing a reseller sales channel, and expanding FalconStor's
direct sales force. Any difficulty in obtaining these OEM and reseller
customers or in attracting qualified sales personnel will negatively impact
FalconStor's financial performance.

The market for IP-based storage solutions is new and uncertain, and
FalconStor's business will suffer if it does not develop as FalconStor
expects.

The rapid adoption of internet protocol (IP)-based storage solutions is
critical to FalconStor's future success. The market for IP-based solutions is
still unproven, making it difficult to predict its potential size or future
growth rate, and there are currently only a handful of companies with IP-based
storage products that are commercially available. Most potential customers have
made substantial investments in their current storage networking
infrastructure, and they may elect to remain with current network architectures
or to adopt new architectures in limited stages or over extended periods of
time. FalconStor will need to convince these potential customers of the
benefits of FalconStor's IP-based storage products for future storage network
infrastructure upgrades or expansions. FalconStor cannot be certain that a
viable market for its products will develop or be sustainable. If this market
does not develop, or develops more slowly than FalconStor expects, FalconStor's
business, financial condition and results of operations would be seriously
harmed.

FalconStor's products may not be accepted by customers or may become obsolete
if FalconStor does not respond rapidly to technological and market changes.

The storage networking infrastructure software market is characterized by
rapid technological change and frequent product and service introductions. The
combined company may be unable to respond quickly or effectively to these
developments. If competitors introduce products, services or technologies that
are better than FalconStor's or that gain greater market acceptance, or if new
industry standards emerge, FalconStor's products and services may become
obsolete, which would materially harm the combined company's business and
results of operations.

If FalconStor's new product introductions are not successful, its operating
results will suffer.

To become a significant supplier within the rapidly evolving storage
networking infrastructure software market, the combined company will need to
respond quickly to develop new products or enhanced features and capabilities
in its current product offerings to effectively satisfy customer expectations.
Although FalconStor's current products are designed for one of the most
significant segments of the storage networking infrastructure software market,
demand may shift to other market segments. Accordingly, the combined company
will need to develop and manufacture new products that address additional
storage networking infrastructure software market segments and emerging
technologies to remain competitive in the data storage software industry.
Neither NPI nor FalconStor can assure you that the combined company will:

. successfully or timely develop or market any new storage networking
infrastructure software products in response to technological changes or
evolving industry standards;

. not experience technical or other difficulties that could delay or
prevent the successful development, introduction or marketing of new
storage networking infrastructure software products;

. successfully qualify new storage networking infrastructure software
products with its customers by meeting customer performance and quality
specifications;

. quickly achieve high volume production of storage networking
infrastructure software products; or

. achieve market acceptance of its new products.

Any failure of the combined company to develop, introduce and integrate
successfully new products for its existing customers or to address specifically
additional market segments could harm its business, financial condition and
operating results.

FalconStor's complex products may have errors or defects which could result in
reduced demand for its products or costly litigation against the combined
company.

FalconStor's IPStor platform is complex and designed to be deployed in large
and complex networks. Many of the combined company's customers will require
that its products be designed to interface with customers' existing networks,
each of which may have different specifications and utilize multiple protocol
standards. Because FalconStor's products are critical to the networks of its
customers, any significant interruption in their service as a result of defects
in the combined company's product within its customers' networks could result
in lost profits or damage to its customers. These problems could cause the
combined company to incur significant service and warranty costs, divert
engineering personnel from product development efforts and significantly impair
the combined company's ability to maintain existing customer relationships and
attract new customers. In addition, a product liability claim, whether
successful or not, would likely be time consuming and expensive to resolve and
would divert management time and attention. Further, if FalconStor is unable to
fix the errors or other problems that may be identified in full deployment, it
would likely experience loss of or delay in revenues and loss of market share
and its business and prospects would suffer.

The loss of one or more of FalconStor's significant customers would harm its
business and operating results.

FalconStor expects to sell most of its products to a limited number of
customers. FalconStor's management expects that a relatively small number of
customers will account for a significant portion of the

combined company's revenue after the merger, and the proportion of its revenue
from these customers could continue to increase in the future. These customers
have a wide variety of suppliers to choose from and therefore could make
substantial demands on the combined company. Even if the combined company
successfully qualifies a product for a given customer, that customer generally
will not be obligated to purchase any minimum volume of products from it and
generally will be able to terminate its relationship with the combined company
at any time. The combined company's ability to maintain strong relationships
with its principal customers is essential to its future performance. If it
loses a key customer or if any of its key customers reduce their orders of the
combined company's products or require it to reduce its prices before it is
able to reduce costs, the combined company's business, financial condition and
operating results would suffer.

FalconStor's business would be adversely affected if it fails to manage its
growth properly.

The combined company plans to expand its operations rapidly to execute
FalconStor's business plan. This growth will place a significant strain on the
combined company's management, systems and resources and will force the
combined company to incur increased operating expenses. In order to grow and
achieve future success, the combined company must:

. retain existing personnel;

. hire, train, manage and retain additional qualified personnel; and

. effectively manage relationships with its customers, suppliers and other
third parties.

Because FalconStor will need to continue to expand, train and manage its
workforce worldwide, the combined company will incur increased operating
expenses. If the combined company does not manage this growth, or if
Falconstor's revenues do not grow as fast as planned, the combined company's
results would be adversely affected.

The combined company's quarterly results may fluctuate significantly which
could cause its stock price to decline.

NPI's quarterly operating results have fluctuated significantly in the past
and the combined company's quarterly operating results may fluctuate
significantly in the future. The combined company's future performance will
depend on many factors, including:

. the average unit selling price of its products;

. changes in product or customer mix;

. existing competitors introducing better products at competitive prices
before it does;

. new competitors entering its market;

. its ability to manage successfully the complex and difficult process of
qualifying its products with its customers;

. its customers canceling, rescheduling or deferring significant orders for
the combined company's products, particularly in anticipation of new
products or enhancements from it or its competitors;

. import or export restrictions on its proprietary technology;

. the availability of adequate capital resources;

. increases in research and development expenditures, particularly as a
percentage of revenue, required to maintain its competitive position;

. changes in the combined company's strategy;

. personnel changes; and

. other general economic and competitive factors.

Many of NPI's and FalconStor's expenses are relatively fixed and difficult
to reduce or modify. As a result, the fixed nature of the combined company's
operating expenses will magnify any adverse effect of a decrease in revenue on
its operating results. As a result of these and other factors, NPI believes
that period to period comparisons of its historical results of operations and
FalconStor's operations are not a good predictor of the combined company's
future performance. If the combined company's future operating results are
below the expectations of stock market analysts, its stock price may decline.

The storage networking infrastructure software market is highly competitive
and intense competition could negatively impact FalconStor's business.

The storage networking infrastructure software market is intensely
competitive even during periods when demand is stable. FalconStor's management
believes that it competes primarily with:

. DataCore; and

. StorageApps.

Many of FalconStor's potential competitors have a number of significant
advantages, including:

. preferred vendor status with customers;

. extensive name recognition and marketing power; and

. significantly greater financial, technical and manufacturing resources.

As a result, those competitors may be able to establish rapidly or expand
storage networking infrastructure software offerings more quickly, adapt to new
technologies and customer requirements faster, and take advantage of
acquisition and other opportunities more readily.

FalconStor's competitors also may:

. consolidate or establish strategic relationships among themselves to
lower their product costs or to otherwise compete more effectively
against it;

. lower their product prices to gain market share; or

. bundle their products with other products to increase demand for their
products.

In addition, new competitors could emerge and rapidly capture market share
including some OEMs with whom FalconStor does business, or hopes to do
business, that may enter the market directly. If the combined company fails to
compete successfully against current or future competitors, its business,
financial condition and operating results may suffer.

The loss of any of FalconStor's key personnel could harm the combined
company's business.

The combined company's success depends upon the continued contributions of
FalconStor's key employees, many of whom would be extremely difficult to
replace. FalconStor does not have key person life insurance on any of its
personnel. Many of FalconStor's senior management and a significant number of
its other employees have been with FalconStor for a short period of time.
Worldwide competition for skilled employees in the storage networking
infrastructure software industry is extremely intense. If the combined company
is unable to retain existing employees of FalconStor or to hire and integrate
new employees, the combined company's business, financial condition and
operating results could suffer. In addition, companies whose employees accept
positions with competitors often claim that the competitors have engaged in
unfair hiring practices. The combined company may be the subject of such claims
in the future as it seeks to hire qualified personnel and could incur
substantial costs defending itself against those claims.

If FalconStor is unable to raise more capital in the future, its business,
financial condition and operating results may suffer.

FalconStor's business is capital intensive and the combined company may need
more capital in the future. The combined company's future capital requirements
will depend on many factors, including:

. the rate of its sales growth;

. the level of its profits or losses;

. the timing and extent of its spending to support facilities upgrades and
product development efforts;

. the timing and size of business or technology acquisitions; and

. the timing of introductions of new products and enhancements to its
existing products.

Any future equity financing will decrease the combined company's
stockholders' percentage equity ownership and may, depending on the price at
which the equity is sold, result in significant economic dilution to the
combined company's stockholders.

If the combined company is not able to raise sufficient capital through
equity financings, the combined company may be required to borrow money to meet
its capital requirements. However, NPI and FalconStor believe that current
market conditions for credit facilities are not as favorable as they have been
at certain times in the past and that the terms on which the remaining
potential lenders are willing to offer such facilities, in many cases, are
restrictive and/or costly. Consequently, the terms and conditions under which
the combined company might obtain such a facility are uncertain. Any failure to
obtain adequate credit facilities on acceptable terms could harm the combined
company's business, financial condition and results of operations.

The board of directors may selectively release shares of NPI common stock
received by the former FalconStor stockholders from lock-up restrictions.

The board of directors of the combined company may, in its sole discretion,
release any or all of the shares of NPI common stock received by the former
FalconStor stockholders from lock-up restrictions. Any release of such shares
from lock-up restrictions may be applied to FalconStor's former stockholders on
a proportionate or selective basis. If the release is selectively applied, the
stockholders whose shares are not released will be forced to hold such shares
while other stockholders may sell their shares. As a result, stockholders whose
shares are not selectively released prior to the end of the one-year period may
be adversely affected.

Future sales of the combined company's common stock may depress its stock
price.

The shares of NPI common stock issued to FalconStor's former stockholders
will become freely tradeable in the public market no later than one year after
the merger. The market price of the combined company's common stock could fall
in response to sales of a large number of shares of its common stock in the
market after the merger or in response to the perception that sales of a large
number of shares could occur. In addition, these sales could create the
perception by the public of difficulties or problems with the combined
company's products and services. As a result, these sales also might make it
more difficult for the combined company to sell equity or equity-related
securities in the future at a time and price that its board of directors deems
appropriate.

NPI's certificate of incorporation and bylaws and Delaware law contain
provisions that could inhibit a takeover that stockholders may consider
favorable.

Certain provisions of NPI's certificate of incorporation and bylaws may
discourage, delay or prevent a change of control or changes in our management
that stockholders consider favorable. These provisions include:

. authorizing the issuance by its board of directors of "blank check"
preferred stock without any action by its stockholders;

. providing for a classified board of directors with staggered, three-year
terms;

. prohibiting stockholder action by written consent;

. limiting the persons who may call special meetings of stockholders; and

. establishing advance notice requirements for nominations for election to
the board of directors or for proposing matters that can be acted on by
stockholders at stockholder meetings.

Delaware law also imposes limitations on persons proposing to merge with or
acquire the combined company. If a change of control or change in management is
delayed or prevented, the market price of the combined company's common stock
could decline. See "Comparison of Rights of Holders of NPI Common Stock and
FalconStor Common Stock," beginning on page 68.

If FalconStor is unable to protect its intellectual property, its business
will suffer.

FalconStor has applied for patent protection on some of its proprietary
technologies. After the merger, the combined company may not receive patents
for its pending or future patent applications, and any patents that it owns or
that are issued to it may be invalidated, circumvented or challenged. Moreover,
the rights granted under any such patent may not provide the combined company
with any competitive advantages. Finally, the combined company's competitors
may develop or otherwise acquire equivalent or superior technology.

NPI and FalconStor also rely on trade secret, copyright and trademark laws,
as well as the confidentiality and other restrictions contained in their
respective sales contracts and confidentiality agreements to protect their
proprietary rights. These legal protections afford only limited protection. The
combined company may have to litigate to enforce patents issued or licensed to
it, to protect trade secrets or know-how owned by it or to determine the
enforceability, scope and validity of its proprietary rights and the
proprietary rights of others. Enforcing or defending the combined company's
proprietary rights could be expensive and might not bring it timely and
effective relief.

The combined company may have to obtain licenses of other parties'
intellectual property and pay royalties. If the combined company is unable to
obtain such licenses, it may have to stop production of its products or alter
its products. In addition, the laws of certain countries in which it sells and
manufactures its products, including various countries in Asia, may not protect
the combined company's products and intellectual property rights to the same
extent as the laws of the United States. The combined company's protective
measures in these countries may be inadequate to protect its proprietary
rights. Any failure to enforce and protect the combined company's intellectual
property rights could harm its business, financial condition and operating
results.

FalconStor's technology may be subject to infringement claims which could harm
its business.

The combined company may become subject to litigation regarding infringement
claims alleged by third parties. Even if the combined company has valid
defenses to such claims, the results of any litigation are inherently
uncertain. Neither NPI nor FalconStor can assure you that the combined company
will be able to defend itself successfully against any such lawsuit. A
favorable outcome by a third party could result in the issuance of an
injunction against the combined company and its products and/or the payment of
monetary damages equal to a royalty, the third party's lost profits or
statutory damages. In the case of a finding of a willful infringement, the
combined company also could be required to pay treble damages and the third
party's attorneys' fees. Accordingly, a litigation outcome favorable to a third
party could harm the combined company's business, financial condition and
operating results.

FalconStor has received correspondence from a third party claiming that some
of FalconStor's employees formerly employed by that third party may have
disclosed proprietary information of the third party in violation of certain
agreements or other obligations to that third party. This third party has also
asserted that FalconStor's intellectual property may be based on or utilizes
its intellectual property. As of the date of this joint proxy
statement/prospectus, no formal action has been taken by the third party.
FalconStor believes these claims are without merit. However, if an action is
commenced against FalconStor, its management may have to devote substantial
attention and resources to defend these claims. An unfavorable result for
FalconStor could have a material adverse effect on the combined company's
business, financial condition and operating results and could limit its ability
to use its intellectual property.

These proxy solicitation materials were mailed on or about ,
2001 to all stockholders entitled to vote at the meeting.

Voting Rights and Solicitation of Proxies; Expenses

This solicitation of proxies is made on behalf of the board of directors of
NPI and the cost thereof will be borne by NPI. NPI has retained the services of
MacKenzie Partners, Inc. to aid in the solicitation of proxies. NPI estimates
that it will pay this solicitor a fee not to exceed $10,000 for its services
and will reimburse the solicitor for reasonable out-of-pocket expenses. The
board of directors may use the services of NPI's directors, officers, and
others to solicit proxies, personally or by telephone and may arrange with
brokerage houses and other custodians, nominees, and fiduciaries to forward
solicitation materials to the beneficial owners of the stock held of record by
such persons and NPI may reimburse them for the fees and reasonable out-of-
pocket expenses incurred in doing so.

On , 2001, NPI had outstanding shares of
common stock, all of which are entitled to vote as a single class with respect
to the proposals presented in this joint proxy statement/prospectus. Each
stockholder of record at the close of business on , 2001, is
entitled to one vote for each share held. NPI's bylaws provide that a majority
of all shares entitled to vote, whether present in person or by proxy, will
constitute a quorum for the transaction of business at the meeting.

Purpose of the NPI Annual Meeting

The purpose of the NPI annual meeting is to vote upon proposals for:

. the approval of the merger agreement and the transactions contemplated by
the merger agreement, including the issuance of shares of NPI common
stock in the merger;

. the amendment of NPI's restated certificate of incorporation to increase
the authorized number of shares of NPI common stock from 60,000,000 to
100,000,000 and to change its corporate name to FalconStor Software,
Inc.;

. if the merger is not completed, the election of Michael Gardner and James
Regel as Class I Directors to serve for three-year terms; and

. if the merger is not completed, the ratification of the selection of
PricewaterhouseCoopers LLP as NPI's independent accountants.

The amendment to NPI's restated certificate of incorporation to increase the
authorized number of shares of NPI common stock and to change its corporate
name to FalconStor Software, Inc. would take effect only if the merger is
approved and completed.

Record Date and Outstanding Shares

The close of business on , 2001 has been fixed by the NPI
board of directors as the record date for determination of the stockholders of
NPI entitled to notice of, and to vote at, the NPI annual meeting or any
postponement or adjournment of the NPI annual meeting. Holders of record of NPI
common stock at the close of business on the record date are entitled to notice
of, and to vote at, the NPI annual meeting. As of the record date, there were
approximately stockholders of record holding an aggregate of approximately
shares of NPI common stock. See "Stock Ownership of Management and
Certain Stockholders" on page 28.

Stock Ownership of Management and Certain Stockholders

As of the record date, the directors and executive officers of NPI
collectively owned approximately % of the outstanding shares. As of the
record date, the directors and executive officers of FalconStor collectively
owned beneficially approximately % of the outstanding shares.

Vote Required

Each stockholder of record of NPI common stock on the record date is
entitled to cast one vote per share, exercisable in person or by properly
executed proxy, on each matter properly submitted for the vote of the
stockholders of NPI at the NPI annual meeting.

Approval of Proposal 1 and Proposal 2 which are related to the approval of
the merger both require the affirmative vote of holders of at least a majority
of the shares of NPI common stock entitled to vote at the annual meeting of
stockholders. Pursuant to voting agreements, each officer and director has
agreed to vote all of his shares in favor of NPI's merger proposal.

In order to comply with the rules of The Nasdaq Stock Market pertaining to
the issuance of new shares, approval for issuances of 20% or more of NPI's
outstanding stock is required by the stockholders of NPI. By approving this
proposal, the stockholders are approving the issuance of more than 20% of the
outstanding shares of NPI's common stock upon the closing of the merger.

Approval of Proposal 3 to elect the two nominees as Class I Directors, if
the merger is not completed, each requires a plurality of the votes cast at the
annual meeting of stockholders.

Approval of Proposal 4 to ratify the appointment of PricewaterhouseCoopers
LLP as the independent accountants for NPI, if the merger is not completed,
requires the affirmative vote of holders of at least a majority of the shares
of NPI common stock entitled to vote at the annual meeting of stockholders.

Quorum; Abstentions; Broker Non-Votes

The presence, in person or by proxy duly authorized, of the holders of a
majority of the outstanding voting shares of NPI common stock will constitute a
quorum for the transaction of business at the annual meeting and any
continuation or adjournment thereof. Broker non-votes (i.e. shares held by
brokers or nominees which are represented at the meeting, but that such broker
or nominee is not empowered to vote on a particular proposal) and abstentions
will be counted in determining whether a quorum is present at the annual
meeting. Abstentions and broker non-votes will have the same effect as a
negative vote on each of the proposals related to the merger.

Abstentions and broker non-votes will have no effect on the election of
directors. Abstentions will have the same effects as a negative vote on the
ratification of NPI's selection of its independent accountants.

Voting of Proxies; Revocation of Proxies

The proxy accompanying this joint proxy statement/prospectus is solicited on
behalf of the NPI board of directors for use at the meeting. Please complete,

the meeting for purposes of establishing a quorum and are also treated as
shares entitled to vote at the special meeting with respect to such matter.

Rights of Dissenting Stockholders

The Delaware General Corporation Law grants appraisal rights in the merger
to the holders of FalconStor's common stock and preferred stock. Under the
Delaware General Corporation Law, FalconStor stockholders may object to the
merger and demand in writing that FalconStor pay the fair value of their
shares. Fair value takes into account all relevant factors but excludes any
appreciation or depreciation in anticipation of the applicable merger.
Stockholders who elect to exercise appraisal rights must comply with all of the
procedures to preserve those rights. We have attached a copy of Section 262 of
the Delaware General Corporation Law (which sets forth the appraisal rights) as
Annex C to this joint proxy statement/prospectus.

Section 262 sets forth the required procedure a stockholder requesting
appraisal rights must follow. Making sure that you actually perfect your
appraisal rights can be complicated. The procedural rules are specific and must
be followed completely. Failure to comply with the procedure may cause a
termination of your appraisal rights. We are providing you only a summary of
your rights and the procedure. The following information is qualified in its
entirety by the provisions of Section 262. Please review Section 262 for the
complete procedure. Neither NPI nor FalconStor will give you any notice other
than as described in this joint proxy statement/prospectus and as required by
the Delaware General Corporation Law.

Appraisal Rights Procedures

If you are a FalconStor stockholder and you wish to exercise your appraisal
rights, you must satisfy the provisions of Section 262 of the Delaware General
Corporation Law. Section 262 requires, in part, the following:

. Your written demand for appraisal: You must deliver a written demand for
appraisal to FalconStor before the vote is taken at the special meeting
of stockholders. The written demand must be separate and apart from any
vote against the merger.

. You refrain from voting for approval of the merger: You must not vote for
approval of the merger agreement. If you vote in favor of the merger
agreement, your right to appraisal will terminate, even if you previously
filed a written demand for appraisal.

. You continuously hold your FalconStor shares: You must continuously hold
your shares of FalconStor stock from the date you make the demand for
appraisal through the closing of the merger. You should read the
paragraphs below for more details on making a demand for appraisal.

. A written demand for appraisal of FalconStor stock is only effective if
it is signed by, or for, the stockholder of record who owns such shares
at the time the demand is made. The demand must be signed as the
stockholder's name appears on its stock certificate(s). If you are the
beneficial owner of FalconStor stock but not the stockholder of record,
you must have the stockholder of record sign a demand for appraisal.

. If you own FalconStor stock in a fiduciary capacity, such as a trustee,
guardian, or custodian, you must disclose the fact that you are signing
the demand for appraisal in that capacity.

. If you own FalconStor stock with more than one person, such as in a joint
tenancy or tenancy in common, all of the owners must sign, or have signed
for them, the demand for appraisal. An authorized agent, which could
include one or more of the joint owners, may sign the demand for
appraisal for a stock holder of record; however, the agent must expressly
disclose who the stockholder of record is and that he is signing the
demand as that stockholder's agent.

. If you are a record owner, such as a broker, who holds FalconStor stock
as a nominee for others, you may exercise a right of appraisal with
respect to the shares held for one or more beneficial owners, while not
exercising such right for other beneficial owners. In such a case, you
should specify in the written demand the number of shares as to which you
wish to demand appraisal. If you do not expressly

specify the number of shares, we will assume that your written demand
covers all the shares of FalconStor stock that are in your name.

. If you are a FalconStor stockholder, you should address the written
demand to FalconStor, Inc., 125 Baylis Road, Suite 140, Melville, New
York 11747, Attention: Jacob Ferng. It is important that FalconStor
receive all written demands before the vote concerning the merger
agreement is taken. As explained above, this written demand should be
signed by, or on behalf of, the stockholder of record. The written demand
for appraisal should specify the stockholder's name and mailing address,
the number of shares of stock owned, and that the stockholder is thereby
demanding appraisal of such stockholder's shares.

. If you fail to comply with any of these conditions and the merger becomes
effective, you will only be entitled to receive the merger consideration
provided in the merger agreement.

. Written Notice: Within ten days after the closing of the merger,
FalconStor must give written notice that the merger has become effective
to each stockholder who has fully complied with the conditions of Section
262.

. Petition with the Chancery Court: Within 120 days after the closing of
the merger, either FalconStor or any stockholder who has complied with
the conditions of Section 262, may file a petition in the Delaware Court
of Chancery. This petition should request that the chancery court
determine the value of the shares of FalconStor stock held by all of the
stockholders who are entitled to appraisal rights. If you intend to
exercise your rights of appraisal, you should file such a petition in the
chancery court. FalconStor has no intention at this time to file such a
petition. Because FalconStor has no obligations to file such a petition,
if you do not file such a petition within 120 days after the closing, you
will lose your rights of appraisal.

. Withdrawal of Demand: If you change your mind and decide you no longer
want appraisal rights, you may withdraw your demand for appraisal rights
at any time within 60 days after the closing of the merger. You may also
withdraw your demand for appraisal rights after 60 days after the closing
of the merger, but only with the written consent of FalconStor. If you
withdraw your demand for appraisal rights, you will receive the merger
consideration provided in the merger agreement.

. Request for Appraisal Rights Statement: If you have complied with the
conditions of Section 262, you are entitled to receive a statement from
FalconStor. This statement will set forth the number of shares that have
demanded appraisal rights, and the number of stockholders who own those
shares. In order to receive this statement, you must send a written
request to FalconStor with 120 days after the closing of the merger.
After the merger, FalconStor has ten days after receiving a request to
mail the statement to the stockholder.

. Chancery Court Procedures: If you properly file a petition for appraisal
in the chancery court and deliver a copy to FalconStor, FalconStor will
then have 20 days to provide the chancery court with a list of the names
and addresses of all stockholders who have demanded appraisal rights and
have not reached an agreement with FalconStor as to the value of their
shares. The chancery court will then send notice of the time and place
fixed for the hearing of the petition to all of the stockholders who have
demanded appraisal rights. If the chancery court decides it is
appropriate, it has the power to conduct a hearing to determine whether
the stockholders have fully complied with Section 262 of the Delaware
General Corporation Law and whether they are entitled to appraisal rights
under that section. The chancery court may also require you to submit
your stock certificates to the Registry in Chancery so that it can note
on the certificates than an appraisal proceeding is pending. If you do
not follow the chancery court's directions, you may be dismissed from the
proceeding.

. Appraisal of Chancery Shares: After the chancery court determines which
stockholders are entitled to appraisal rights, the chancery court will
appraise the shares of stock. To determine the fair value of the shares,
the chancery court will consider all relevant factors except for any
appreciation or depreciation due to the anticipation or accomplishment of
the merger. After the chancery court determines the fair

value of the shares, it will direct FalconStor to pay that value to the
stockholders who are entitled to appraisal rights. The chancery court can
also direct FalconStor to pay interest, simple or compound, on that value
if the chancery court determines that interest is appropriate. In order to
receive the fair value for your shares, you must surrender your stock
certificates to FalconStor.

. The chancery court could determine that the fair value of shares of
FalconStor stock is more than, the same as, or less than the merger
consideration. In other words, if you demand appraisal rights, you could
receive less consideration than you would under the merger agreement.

. Costs and Expenses of Appraisal Proceeding: The costs and expenses of the
appraisal proceeding may be assessed against FalconStor and the
stockholders participating in the appraisal proceeding, as the chancery
court deems equitable under the circumstances. You can request that the
chancery court determine the amount of interest, if any, FalconStor
should pay on the value of stock owned by stockholders entitled to the
payment of interest. You may also request that the chancery court
allocate the expense of the appraisal action incurred by any stockholder
pro rata against the value of all of the shares entitled to appraisal.

. Loss of Stockholders' Rights: If you demand appraisal rights, after the
closing of the merger you will not be entitled to:

. vote your shares of stock, for any purpose, for which you have demanded
appraisal rights;

. receive payment of dividends or any other distribution with respect to
such shares, except for dividends or distributions, if any, that are
payable to holders of record as of a record date prior to the effective
time of merger; or

. receive the payment of the consideration provided for in the merger
agreement.

. However, you can regain these rights if no petition for an appraisal is
filed with 120 days after the closing of the merger, or if you deliver
to FalconStor a written withdrawal of your demand for an appraisal and
your acceptance of the merger, either within 60 days after the closing
of the merger or with the written consent of FalconStor. As explained
above, these actions will also terminate your appraisal rights.
However, an appraisal proceeding in the chancery court cannot be
dismissed unless the chancery court approves. The chancery court may
condition its approval upon any terms that it deems just.

. If you fail to comply strictly with these procedures you will lose your
appraisal rights. Consequently, if you wish to exercise your appraisal
rights, we strongly urge you to consult a legal advisor before attempting
to exercise your appraisal rights.

NPI AND FALCONSTOR
PROPOSAL NO. 1

APPROVAL OF ADOPTION OF THE MERGER AGREEMENT
AND THE MERGER CONTEMPLATED THEREUNDER

THE MERGER

This section of the joint proxy statement/prospectus describes the proposed
merger. While NPI and FalconStor believe that the description in this section
covers the material terms of the merger and the related transactions, this
summary may not contain all of the information that is important to you. You
should carefully read this entire document and the other documents NPI and
FalconStor have referred to in this joint proxy statement/prospectus for a more
complete understanding of the merger.

Background of the Merger

In December 1999, NPI engaged Lehman Brothers Inc. to identify potential
strategic merger opportunities for NPI. During the first half of 2000, NPI and
Lehman Brothers held preliminary discussions with a number of companies in the
networking equipment industry regarding potential combinations, but none of the
discussions proceeded beyond preliminary information exchanges.

In the second quarter of 2000, as part of their independent partnering
strategies, NPI and FalconStor began working together to evaluate each other's
technology. In September 2000, James Regel, NPI's current chief executive
officer, took responsibility for managing NPI's relationship with FalconStor.
Subsequently, NPI and FalconStor held a number of meetings and discussions
about integration of FalconStor's software with NPI's switching technology. As
a result of his favorable impression of FalconStor's technology and market
opportunity gained in the course of these discussions, Mr. Regel consulted with
Glenn Penisten, NPI's chairman of the board of directors, about the possibility
of merging with FalconStor. Mr. Penisten contacted Barry Rubenstein,
FalconStor's chairman of the board of directors, in November 2000 to inquire
about FalconStor's interest in a merger with NPI. Mr. Rubenstein indicated that
FalconStor would consider a merger with NPI, but that FalconStor was currently
focused on raising capital in a private financing. Mr. Penisten instructed
Mr. Regel to continue working with FalconStor to evaluate the advisability of a
merger. In December 2000, NPI began development of a switch platform for
FalconStor's storage networking infrastructure software, and NPI's management
began to focus attention on means to enter the growing storage networking
market.

In January 2001, NPI's management commissioned an independent consulting
firm to evaluate NPI's opportunities in the Ethernet switching and storage
networking markets. Mr. Regel communicated the preliminary results of that
evaluation to Mr. Penisten in early February. The report concluded that NPI's
current and planned technology lacked features and pricing that would make it
competitive. The study also concluded that, although the storage networking
market was a rapidly growing market with a number of compelling opportunities,
NPI as a stand-alone company lacked the resources and reputation to exploit
those opportunities. As a result, Mr. Penisten contacted Mr. Rubenstein in
early February to discuss the terms of a merger of NPI and FalconStor. Mr.
Penisten and Mr. Rubenstein had several telephone conversations during February
about the proposed terms. During the same period and continuing through
February, Mr. Regel had several meetings and discussions with ReiJane Huai,
FalconStor's chief executive officer, and other members of the FalconStor
management team, at which they discussed potential benefits of the proposed
merger transaction. As a result of progress made in these discussions, NPI
requested that its outside counsel, Gray Cary Ware & Freidenrich LLP, prepare a
preliminary term sheet. The initial draft of the term sheet was delivered to
FalconStor during the week of February 11, 2001.

Over the following two weeks, Mr. Penisten and Mr. Rubenstein had several
telephone conversations during which they discussed the proposed terms. In the
course of these conversations, Mr. Rubenstein indicated that FalconStor was in
discussions with various investors to raise additional capital to facilitate
the implementation of its business plan. Mr. Rubenstein told Mr. Regel that
FalconStor had received indications of interest from certain venture capital
sources and at least one term sheet from a proposed venture capital

investor for a convertible preferred stock financing on terms similar to those
that were negotiated by FalconStor and NPI. Mr. Rubenstein suggested that NPI
consider an equity investment in FalconStor at the same time that NPI continued
to evaluate whether a merger of the two companies would be in the best
interests of NPI's stockholders. Mr. Rubenstein and Mr. Regel continued these
discussions, and NPI agreed to a $25,000,000 equity investment by NPI in
FalconStor. As a result of these discussions, NPI requested that Gray Cary
prepare a revised term sheet reflecting the proposed investment.

On February 27, 2001, the NPI board of directors held a telephonic meeting
attended by all of the NPI directors, as well as James Williams, NPI's chief
financial officer, and a representative of Gray Cary. Mr. Penisten informed the
other directors about the substance of the discussions held with FalconStor
over the preceding months and described the terms of the proposed transaction.
Both Mr. Penisten and Mr. Regel expressed their views that, based in part on
the challenges facing NPI in executing its current business plan, the merger
transaction would be beneficial to NPI's stockholders. The other members of the
NPI board asked a number of questions about the proposed terms, and Scott
Stanton of Gray Cary led a discussion concerning the fiduciary duties of the
board in considering a strategic combination. At the conclusion of the meeting,
the board authorized management to complete negotiation of the term sheet and
to prepare and negotiate definitive transaction documents reflecting those
terms, subject to further approval of the NPI board.

Between February 27 and March 8, 2001, NPI management, FalconStor management
and their respective legal advisors continued to negotiate the specific terms
of the preliminary term sheet. On March 8, 2001, NPI and FalconStor executed
and delivered a letter agreement pursuant to which both parties agreed to
negotiate exclusively with each other for 30 days in good faith to enter into
definitive legal agreements on substantially the terms outlined in the
preliminary term sheet. The parties concurrently entered into a mutual non-
disclosure agreement.

Beginning in the week of March 12, 2001, legal advisors for NPI and
FalconStor began their respective due diligence investigations. On March 14,
2001, Gray Cary delivered the initial draft of an option agreement to Olshan
Grundman Frome Rosenzweig & Wolosky LLP, FalconStor's outside counsel, pursuant
to which NPI would have the exclusive right to require FalconStor to merge with
NPI pursuant to the terms of the merger agreement to be negotiated between the
parties. The option agreement is attached to this joint proxy
statement/prospectus as Annex F. On March 15, 2001, Olshan Grundman delivered
the initial drafts of the agreements governing NPI's purchase of $25,000,000 of
FalconStor Series C preferred stock. Also on March 15, 2001, Mr. Regel and Mr.
Williams met with representatives of Lehman Brothers to inform them of the
proposed transaction and to begin negotiations regarding a formal extension of
Lehman Brothers' engagement as NPI's financial advisor in the transaction. On
March 19, 2001, NPI and Lehman Brothers executed an engagement letter pursuant
to which Lehman Brothers agreed to act as NPI's financial advisor with respect
to the transaction.

On March 19 and 20, 2001, representatives of NPI, FalconStor, Lehman
Brothers, Credit Suisse First Boston, Gray Cary, Olshan Grundman and
PricewaterhouseCoopers LLP, NPI's accounting advisor, met at Lehman Brothers'
offices in Menlo Park, California, to conduct financial, technical and market
due diligence investigations.

Also on March 19 and 20, 2001, legal advisors for NPI and FalconStor
negotiated the terms of a waiver letter pursuant to which FalconStor agreed
that NPI would not violate the terms of the exclusive negotiation agreement if
it solicited offers to purchase its Ethernet switching business. This waiver
letter was signed on March 21, 2001.

On March 20, 2001, the NPI board held a telephonic meeting attended by a
majority of the NPI directors, Mr. Williams and representatives of Gray Cary
and Lehman Brothers. The board was provided with a status report on the results
of the negotiations and due diligence investigations conducted since the last
NPI board meeting on February 27, 2001. The Lehman Brothers representatives
updated the board on their strategy to find a purchaser for NPI's Ethernet
switching business. Also on March 20, 2001, Gray Cary delivered to Olshan
Grundman the initial draft of the merger agreement to be attached to the option
agreement.

During the period from March 20 through March 30, 2001, representatives of
both parties continued negotiating the terms of the option agreement, the
related voting agreements, the Series C preferred stock financing documents and
the merger agreement. On March 28, 2001, Gray Cary distributed to each member
of the NPI board a package containing drafts of all the transaction documents
along with explanatory material. On March 29, 2001, the parties exchanged draft
disclosure schedules to the merger agreement.

On March 29, 2001, the FalconStor board held a telephonic meeting, at which
representatives of Olshan Grundman and Credit Suisse First Boston also
attended. The board was provided with a status on the results of the
negotiations and due diligence investigation of NPI. The board of directors
analyzed the principal terms of the private placement and merger agreement and
various alternatives FalconStor could adopt. During this meeting, Steven
Wolosky of Olshan Grundman made a detailed presentation to the FalconStor board
concerning its fiduciary duties in considering the private placement and the
merger. The FalconStor board held a full discussion of the merits of the
private placement and the option agreement and proposed merger agreement. The
FalconStor board unanimously approved the option agreement, unanimously found
the merger to be fair to, advisable for, and in the best interests of,
FalconStor and its stockholders, unanimously approved the terms of the merger
and the merger agreement and resolved to recommend that the stockholders of
FalconStor adopt and approve the merger agreement and the merger in the event
that NPI exercised the option.

On March 30, 2001, the NPI board held a meeting at NPI's offices in Fremont,
California, together with Mr. Williams and Mr. Stanton of Gray Cary, to review
the principal terms of the proposed transaction, including the status and
timing of the transaction. Mr. Stanton made a detailed presentation to the NPI
board concerning its fiduciary duties in considering the investment in
FalconStor and the merger. Mr. Stanton also reported to the NPI board on the
results of the legal due diligence investigation of FalconStor. Representatives
of PricewaterhouseCoopers joined the meeting by telephone and made a
presentation to the NPI board concerning the results of their due diligence
investigation of FalconStor. Representatives of Lehman Brothers then joined the
meeting and reviewed with the NPI board Lehman Brothers' financial analysis of
the exchange ratio and delivered an oral opinion on behalf of Lehman Brothers,
confirmed by delivery of a written opinion dated as of March 30, 2001, the
effective date of the option agreement, to the effect that, as of the date of
the opinion and based on and subject to the matters described in the opinion,
the aggregate consideration to be paid by NPI pursuant to the terms of the
merger agreement attached to the option agreement to acquire all the capital
stock of FalconStor, was fair, from a financial point of view, to NPI and its
stockholders. After excusing the Lehman Brothers representatives, the NPI board
held a full discussion of the merits of the proposed investment, the merger,
the merger agreement and the option agreement. The directors then unanimously
concluded that it was in the best interests of NPI to approve the investment
and the option agreement. Following the meeting, members of NPI and FalconStor
management and their respective legal and financial advisors concluded final
negotiations of the transaction documents and the parties executed the Series C
investment documents and the option agreement.

On April 2, 2001, the parties announced the investment and the option
agreement, and NPI transferred $25,000,000 to FalconStor as payment of the
purchase price for the shares of FalconStor Series C preferred stock.

Prior to NPI's exercise of the option, FalconStor continued to discuss its
private placement with potential investors. On May 3, 2001, FalconStor closed
its private placement, which raised approximately $8,150,000 for FalconStor in
addition to the $25,000,000 previously received from NPI. Additional investors
in the private placement included Accton Technology Corporation, Accura
Ventures, Odeon Capital Partners, Systex Corporation, Taiwan-Sok Shin Kong
Security Co., Ltd. and Taiwan Special Opportunities Fund III.

On May 3, 2001, the NPI board held a meeting at NPI's offices in Fremont,
California, together with Mr. Williams and Mr. Stanton to consider the
advisability of exercising the option and approving the merger agreement. Mr.
Stanton again reviewed for the board its fiduciary duties in considering the
proposed merger as well as the specific terms of the option agreement and
merger agreement. Representatives of Lehman Brothers joined the meeting and
orally reconfirmed their opinion delivered at the March 30, 2001 board meeting
that, as of the date of the opinion and based on and subject to the matters
described in the opinion, the aggregate

consideration to be paid by NPI pursuant to the terms of the merger agreement
to acquire all the capital stock of FalconStor, was fair, from a financial
point of view, to NPI and its stockholders. After a full discussion, the NPI
directors unanimously concluded that the merger was in the best interests of
NPI and its stockholders and declared the merger advisable, and unanimously
approved the exercise of the option, the terms of the merger and the merger
agreement and resolved to recommend that the NPI stockholders vote to adopt the
merger agreement and approve the merger. On May 4, 2001, NPI exercised the
option, and the parties executed and delivered the merger agreement.

Reasons for the Merger

General

The board of directors of NPI, at a meeting held on May 3, 2001, unanimously
approved the merger agreement, unanimously found the merger to be fair to,
advisable for, and in the best interests of, NPI and its stockholders, and
unanimously resolved to recommend that the stockholders of NPI adopt and
approve the merger agreement and the merger and the transactions related to the
consummation of the merger. The board of directors of FalconStor, at a meeting
held on March 29, 2001, unanimously approved the option agreement granting NPI
the right to cause the merger to occur pursuant to the merger agreement,
unanimously found the merger to be fair to, advisable for, and in the best
interests of, FalconStor and its stockholders, and unanimously resolved to
recommend that the stockholders of FalconStor adopt and approve the merger
agreement and the merger in the event that NPI exercised the option.

In reaching its separate decision, each board consulted with its senior
management, and financial and legal advisors, and considered a number of
factors. In view of the complexity and wide variety of information and factors,
both positive and negative, considered by each board, neither board found it
practical to qualify, rank or otherwise assign any relative or specific weights
to the factors it considered. In addition, neither board reached any specific
conclusion with respect to each of the factors it considered, or any aspect of
any particular factor. Instead, each board conducted an overall analysis of the
factors it considered. In considering those factors, individual members of each
board may have given weight to different factors. Each board considered all of
those factors as a whole and believed that those factors supported its
decision.

The factors considered by each board were not identical to the factors
considered by the other board. However, both boards identified certain material
benefits, common to both companies and their respective stockholders, that both
boards expect will result from the merger, as well as certain risks affecting
both companies in connection with the merger and certain other considerations
common to both companies. These benefits, risks and other considerations are
described immediately below. Following the discussion of those matters, the
separate factors, both positive and negative, that each board separately
considered are described. This section, read as a whole, includes the material
factors considered by each board in approving the merger.

Joint Reasons for the Merger

Both boards believe that the combination of NPI and FalconStor will create a
stronger, more fully developed industry participant, with enhanced prospects
for continued viability, by:

. allowing the combined company to leverage the financial resources of NPI
and the products, partners, technology and business plan of FalconStor;
and

. providing FalconStor with access to public equity markets to enhance
stockholder liquidity and the combined company's ability to use equity
compensation to attract and retain talented technical and management
personnel to build FalconStor's market presence.

Both boards also recognize the risks inherent in the transaction, including:

. the risk that the combined company may not be able to realize, fully or
at all, the potential benefits of the combination;

. the possibility that even if the merger is approved by the stockholders
of both companies, it may not be completed;

. the possibility that potential disruption to existing and prospective
relationships could result from the announcement or completion of the
merger;

. the significant adverse impact to the potential future net income of the
combined company that will arise due to the non-cash charges for the
amortization of goodwill and other intangibles resulting from the impact
of purchase accounting on the merger;

. the substantial charges to be incurred in connection with the merger,
including transaction expenses, and employee retention and severance
costs; and

. the other risks described under "Risk Factors Related to the Merger"
beginning on page 16.

Both boards determined that the potential benefits of the merger outweigh
the potential risks. In the course of their separate deliberations, each board
also considered the following factors:

. historical information concerning the businesses, operations, financial
condition, results of operations, technology, management, competitive
positions, and prospects of NPI and FalconStor as stand-alone businesses,
including results of operations during their most recent fiscal periods;

. the current and historical economic and market conditions and industry
environment in the business of each company, including market prices,
volatility and trading data for NPI common stock;

. the analyses presented by their respective financial advisors; and

. the results of their respective due diligence process.

Each board also determined that the provisions of the merger agreement,
including the exchange ratio, the parties' representations, warranties and
covenants, and the conditions to their respective obligations, were the
reasonable product of vigorous arms-length negotiations. Each board also
considered the provisions of the merger agreement that prohibit solicitation of
third-party bids and the acceptance, approval or recommendation of any
unsolicited third-party bid, and the provisions which require NPI to pay
FalconStor $3,000,000 upon certain termination events. Each board concluded
that the provisions of the relevant documents reasonably protected the
interests of the applicable company's stockholders and did not present any
significant impediments to proceeding with the merger considering all of the
circumstances.

Reasons of the NPI Board

In the course of its deliberations, NPI's board of directors took the
following additional actions:

. the board evaluated the significantly diminished prospects for NPI on a
stand-alone basis in light of:

. the overall decline in spending on information technology
infrastructure products;

. increasing competition from larger companies;

. NPI's continuously declining operating results; and

. the substantial investment of time and financial resources that would
be required for NPI to develop and market next generation switching
products that would enable NPI to gain market share and reach
profitability;

. the board evaluated NPI's ability to maintain a sufficient amount of
assets to satisfy the closing conditions in the merger agreement and
determined that discontinuation of NPI's existing Ethernet switching
business, either through a divestiture or closure, would be required;

. the board evaluated the value NPI stockholders would receive if NPI's
business were wound up and dissolved and its liquid assets distributed to
stockholders; and

. the board took into account that, as a result of the exchange ratio, the
former stockholders of FalconStor would, immediately following the
completion of the merger, collectively own more than a majority of NPI's
outstanding shares. However, the board of directors considered that this
was acceptable because:

. the merger would provide NPI's existing stockholders with a significant
potential for increased share value; and

. the board received the written opinion of Lehman Brothers dated as of
March 30, 2001, and updated as of May 3, 2001, that as of May 3, 2001
and based upon and subject to the assumptions, qualifications and
limitations stated in that opinion, the aggregate consideration to be
paid by NPI for the FalconStar equity was fair to NPI and its
stockholders from a financial point of view. See "Opinion of NPI's
Financial Advisor" beginning on page 41.

Reasons of the FalconStor Board

In the course of its deliberations, FalconStor's board of directors
considered the following additional factors, among others:

. that the merger is expected to be tax-free to FalconStor and its
stockholders;

. the cash on hand that NPI would provide to FalconStor to continue
executing its business plan;

. the increased value to holders of FalconStor capital stock that was
likely to result from allowing the combined company to leverage NPI's
financial resources to fund the development of FalconStor's business; and

. the potential benefits of public ownership at a time when access to the
public equity markets is more difficult.

The board also considered the following potentially negative factors in its
deliberations concerning the merger:

. the risk that the merger might not be consummated;

. the risk associated with fluctuations in NPI's stock price prior to the
closing of the merger that the per share value of the consideration to be
received by holders of FalconStor capital stock might be significantly
less than the price per share implied by the exchange ratio immediately
prior to the announcement of the merger because the exchange ratio will
not be adjusted as a result of changes in the market price of NPI common
stock;

. the risk that the transaction would not be viewed by the Internal Revenue
Service as meeting all requirements to qualify as non-taxable to
FalconStor and its stockholders; and

. other applicable risks described in this joint proxy statement/prospectus
statement under "Risk Factors" beginning on page 16.

The board concluded that the potential benefits of the merger to
FalconStor's stockholders outweighed these factors.

RECOMMENDATIONS OF THE NPI AND THE FALCONSTOR BOARDS OF DIRECTORS

Recommendation of the NPI Board

The NPI board of directors has unanimously determined that the terms of the
merger are fair to, advisable for, and in the best interests of NPI and the NPI
stockholders. Accordingly, the NPI board of directors recommends that NPI
stockholders vote FOR the proposal to adopt the merger agreement and approve
the merger. Approval of the proposal to adopt the merger agreement will
constitute approval of all transactions contemplated by the merger agreement.

Recommendation of the FalconStor Board

The FalconStor board of directors has unanimously determined that the terms
of the merger agreement and the merger are fair to, advisable for, and in the
best interests of FalconStor and the FalconStor stockholders. Accordingly, the
FalconStor board of directors recommends that FalconStor stockholders vote FOR
the proposal to adopt the merger agreement and approve the merger. Approval of
the proposal to adopt the merger agreement will constitute approval of all
transactions contemplated by the merger agreement, including, without
limitation, the conversion of all outstanding shares of FalconStor preferred
stock to FalconStor common stock immediately prior to the merger.

Vote Required

The affirmative vote of a majority of all outstanding shares of NPI common
stock is required for approval of this proposal.

The affirmative vote of at least a majority of the outstanding voting power
of the common stock and the preferred stock of FalconStor voting together as a
single class, and a majority of the outstanding shares of Series A preferred
stock, two-thirds of the outstanding shares of Series B preferred stock, and a
majority of the outstanding shares of Series C preferred stock, each series
voting separately, is required for approval of this proposal.

Abstentions and broker non-votes will each have the same effect as a
negative vote on this proposal.

Opinion of NPI's Financial Advisor

General. Lehman Brothers Inc. has acted as financial advisor to NPI in
connection with the merger. On March 30, 2001, Lehman Brothers rendered its
opinion to the NPI board of directors that as of such date, and based upon and
subject to certain matters stated therein, from a financial point of view, the
aggregate consideration to be paid by NPI for the FalconStor common stock in
the merger is fair to NPI and its stockholders.

At the time Lehman Brothers delivered its opinion, it understood that all of
the issued and outstanding shares of capital stock of FalconStor and all
outstanding, unexpired and unexercised options, warrants, convertible notes,
and other rights to acquire or receive shares of FalconStor common stock
(collectively, the "FalconStor Equity") would be converted into the right to
receive, in the aggregate, between 68.9% and 71.5% of the shares of common
stock of NPI on a fully-diluted basis (the "Aggregate Consideration"). Lehman
Brothers further understood that the exact percentage of shares to be paid by
NPI would vary depending (1) the amount of cash, cash equivalents and short
terms investments held by NPI at the time of the Proposed Transaction and (2)
the amount of proceeds received by FalconStor from the sale of its Series C
preferred stock to investors other than NPI.

The full text of Lehman Brothers' written opinion dated March 30, 2001 is
included as Annex B to this joint proxy statement/prospectus. Stockholders may
read such opinion for a discussion of the assumptions made, procedures
followed, factors considered and limitations upon the review undertaken by
Lehman Brothers in rendering its opinion. The following is a summary of Lehman
Brothers' opinion and the methodology that Lehman Brothers used to render its
opinion.

Lehman Brothers' advisory services and opinion were provided for the
information and assistance of the NPI board of directors in connection with its
consideration of the merger. Lehman Brothers' opinion is not intended to be and
does not constitute a recommendation to any stockholder of NPI as to how such
stockholder should vote with respect to the merger. Lehman Brothers was not
requested to opine as to, and Lehman Brothers' opinion does not address, NPI's
underlying business decision to proceed with or effect the merger.

In arriving at its opinion, Lehman Brothers reviewed and analyzed:

. the merger agreement and the specific terms of the merger;

. publicly available information concerning NPI that Lehman Brothers
believed to be relevant to its analysis, including NPI's Annual Report on
Form 10-K for the fiscal year ended December 31, 1999 and NPI's Quarterly
Reports on Form 10-Q for the quarters ended March 31, June 30, and
September 30, 2000 and NPI's earnings release for the quarter and fiscal
year ended December 31, 2000;

. financial and operating information with respect to the business,
operations and prospects of NPI furnished to Lehman Brothers by NPI,
including projections for the next five years prepared by the management
of NPI (the "Company Projections");

. a trading history of NPI's common stock over the past one year and five
years, and a comparison of that trading history with those of other
companies that Lehman Brothers deemed relevant;

. financial and operating information with respect to the business,
operations and prospects of FalconStor furnished to Lehman Brothers by
NPI and FalconStor, including projections for the next three years
prepared by the management of FalconStor (the "FalconStor Projections");

. a comparison of the historical financial results and present financial
condition of NPI and FalconStor with those of other companies that Lehman
Brothers deemed relevant;

. a comparison of the financial terms of the merger with the financial
terms of certain other transactions that Lehman Brothers deemed relevant;

. a possible liquidation of NPI, including the cash that would be
distributed to NPI's stockholders in connection with such liquidation;
and

. the results of Lehman Brothers' efforts to solicit indications of
interest from third parties with respect to a purchase of NPI or its
operating business.

In addition, Lehman Brothers had discussions with the managements of
FalconStor and NPI concerning the business, operations, assets, financial
condition and prospects of FalconStor (including the FalconStor Projections)
and discussions with the management of NPI concerning its business, operation,
assets, financial condition and prospects, and undertook such other studies,
analyses and investigations as Lehman Brothers deemed appropriate.

In arriving at its opinion, Lehman Brothers assumed and relied upon the
accuracy and completeness of the financial and other information used by it
without assuming any responsibility for independent verification of such
information. Lehman Brothers also relied upon the assurances of the managements
of NPI and FalconStor that they were not aware of any facts or circumstances
that would make the information relied upon by Lehman Brothers inaccurate or
misleading. With respect to the Company Projections, upon advice of NPI, Lehman
Brothers assumed that such projections were reasonably prepared on a basis
reflecting the best currently available estimates and judgments of the
management of NPI as to the future financial performance of NPI and that NPI
would perform substantially in accordance with the Company Projections. With
respect to the FalconStor Projections, upon advice of FalconStor and NPI,
Lehman Brothers assumed that such projections were reasonably prepared on a
basis reflecting the best currently available estimates and judgments of the
management of FalconStor as to the future financial performance of FalconStor
and that FalconStor would perform substantially in accordance with the
FalconStor Projections. In arriving at its opinion, Lehman Brothers

did not conduct a physical inspection of the properties and facilities of NPI
or FalconStor. Lehman Brothers also did not make or obtain any evaluations or
appraisals of the assets or liabilities of NPI or FalconStor. Lehman Brothers'
opinion was necessarily based upon market, economic and other conditions as
they existed on, and could be evaluated as of, the date of such opinion.

In arriving at its opinion, Lehman Brothers did not ascribe a specific range
of value to NPI or FalconStor, but rather made its determination as to the
fairness, from a financial point of view, to NPI of the aggregate consideration
to be paid by NPI for the FalconStor common stock in the merger on the basis of
the financial and comparative analyses described below. The preparation of a
fairness opinion involves various determinations as to the most appropriate and
relevant methods of financial and comparative analysis and the application of
those methods to the particular circumstances, and therefore, such an opinion
is not readily susceptible to summary description. Furthermore, in arriving at
its opinion, Lehman Brothers did not attribute any particular weight to any
analysis or factor considered by it, but rather made qualitative judgments as
to the significance and relevance of each analysis and factor. Accordingly,
Lehman Brothers believes that its analyses must be considered as a whole and
that considering any portion of such analyses and factors, without considering
all analyses and factors as a whole, could create a misleading or incomplete
view of the process underlying its opinion. In its analyses, Lehman Brothers
made numerous assumptions with respect to industry performance, general
business and economic conditions and other matters, many of which are beyond
the control of NPI and FalconStor. None of NPI, FalconStor, Lehman Brothers or
any other person assumes responsibility if future results are materially
different from those discussed. Any estimates contained in Lehman Brothers'
analyses were not necessarily indicative of actual values or predictive of
future results or values, which may be significantly more or less favorable
than as set forth in the analyses. In addition, analyses relating to the value
of businesses do not purport to be appraisals or to reflect the prices at which
businesses actually may be sold.

The following is a summary of the material financial analyses used by Lehman
Brothers in connection with rendering its opinion to the NPI board of
directors. Some of the summaries of the financial and comparative analyses
include information presented in tabular format. In order to fully understand
the methodologies used by Lehman Brothers and the results of its financial and
comparative analyses, the tables must be read together with the text of each
summary. The tables alone do not constitute a complete description of the
financial and comparative analyses. Accordingly, the information presented in
the tables and described below must be considered as a whole. Considering any
portion of such analyses and of the factors considered, without considering all
analyses and factors as a whole, could create a misleading or incomplete view
of the process underlying Lehman Brothers' opinion.

In order to calculate the transaction multiples for the merger, Lehman
Brothers estimated the implied enterprise value of FalconStor based on NPI's
closing price of $6.97 as of March 29, 2001 and based on the amount of cash
contributed by NPI to the combined company. Under these two scenarios, Lehman
Brothers used the mean of FalconStor's pro forma ownership percentage
calculated based on the minimum and maximum Series C preferred stock investment
of $0 and $20,000,000 and the minimum and maximum NPI closing cash balances of
$80,000,000 and $90,000,000 and estimating the number of outstanding, in-the-
money options for both NPI and FalconStor to calculate the transaction
multiples.

Lehman Brothers used two projections cases in the analyses below, namely the
Base Case and the Conservative Case. The Base Case was computed using the
FalconStor Projections through 2003 and Lehman Brothers estimates thereafter.
The Conservative Case was computed by Lehman Brothers after considering certain
somewhat more conservative assumptions and estimates, which resulted in certain
adjustments to the FalconStor Projections.

Comparable Company Analysis. Using publicly available information, Lehman
Brothers compared selected financial data of FalconStor with similar data of
selected companies engaged in businesses considered by Lehman Brothers to be
comparable to that of FalconStor. Specifically, Lehman Brothers included in its
review the following storage companies: VERITAS Software Corp.; BMC Software,
Inc.; Computer Associates, Inc.; Compuware Corp.; Legato Systems, Inc.; OTG
Software, Inc.; and Gadzoox Networks, Inc.

For each of the selected companies, Lehman Brothers calculated the ratio of
the enterprise value to the mean revenue estimates for the calendar year 2002
reported by First Call Corporation. The enterprise value of each company was
obtained by adding its short and long term debt to the sum of the market value
of its common equity, the value of any preferred stock and the book value of
any minority interest, and subtracting its cash and cash equivalents. Lehman
Brothers also calculated the ratio of the revenue multiple to the estimated
five-year revenue growth rate. The following table presents the earnings and
revenue multiples:

Companies.............................. 2.8x 0.19x
Median of Selected Storage Comparable
Companies.............................. 2.6x 0.15x

Because of the inherent differences between the businesses, operations,
financial conditions and prospects of FalconStor and the businesses,
operations, financial conditions and prospects of the companies included in its
comparable company groups, Lehman Brothers believed that it was inappropriate
to rely solely on the quantitative results of the analysis, and accordingly,
also made qualitative judgments concerning differences between the financial
and operating characteristics of FalconStor and the companies in its comparable
company group that would affect the public trading value of FalconStor and the
comparable companies. In particular, Lehman Brothers considered markets served,
rates of growth and profitability of FalconStor and each of the companies in
the comparable company group. Lehman Brothers concluded that such analysis was
supportive of its opinion.

Comparable Transaction Analysis. The comparable transaction analysis
provides a market benchmark based on the consideration paid in selected
comparable transactions. For this analysis, Lehman Brothers reviewed publicly
available information to determine the purchase prices and multiples paid in 11
acquisitions of public and private storage software companies since January 1,
1996.

Lehman Brothers divided the enterprise value of the acquired company in the
relevant transactions by the total revenue for the following four consecutive
quarters, or Forward 4Q. In addition, Lehman Brothers analyzed the value per
employee for private storage companies. The following tables show the revenue
multiples and value per employee for the selected transactions:

NPI)................................................... $3.1

Mean of Selected Comparable Private Transactions........ $5.4
Median of Selected Comparable Private Transactions...... $5.5

Because the reasons for and the circumstances surrounding each of the
transactions analyzed were so diverse and because of the inherent differences
in the businesses, operations, financial conditions and prospects of FalconStor
and the businesses, operations, and financial conditions of the companies
included in the comparable transactions group, Lehman Brothers believed that a
purely quantitative comparable transaction analysis would not be particularly
meaningful in the context of the merger. Lehman Brothers believed that the
appropriate use of a comparable transaction analysis in this instance would
involve qualitative judgments concerning the differences between the
characteristics of these transactions and the merger which would affect the
acquisition values of the acquired companies and FalconStor. In particular,
Lehman Brothers considered markets served, rates of growth, and profitability
of FalconStor, and each of the acquired companies, as well as business and
market conditions existing at the time of the merger as compared to those
existing when these transactions were executed. Lehman Brothers concluded that
such analysis was supportive of its opinion.

Discounted Cash Flow Analysis. As part of its analysis, Lehman Brothers
prepared a discounted after-tax cash flow model that was based upon financial
projections prepared by the management of FalconStor. Lehman Brothers used an
after tax discount rate of 30% and a terminal value based on a range of forward
revenue multiples of 3.0x to 4.0x. Lehman Brothers concluded that such analysis
was supportive of its opinion.

Lehman Brothers is an internationally recognized investment banking firm
and, as part of its investment banking activities, is regularly engaged in the
valuation of businesses and their securities in connection with mergers and
acquisitions, negotiated underwritings, competitive bids, secondary
distributions of listed and unlisted securities, private placements and
valuations for corporate and other purposes. The NPI board selected Lehman
Brothers because of its expertise, reputation and familiarity with NPI and the
communications equipment industry generally and because its investment banking
professionals have substantial experience in transactions comparable to the
merger.

NPI has agreed to pay Lehman Brothers customary fees for the advisory
services rendered by Lehman Brothers in connection with the proposed merger. In
addition, NPI has agreed to reimburse Lehman Brothers for reasonable
out-of-pocket expenses incurred in connection with the merger and to indemnify
Lehman Brothers for certain liabilities that may arise out of its engagement by
NPI and the rendering of Lehman Brothers' opinion. Lehman Brothers has
previously rendered investment banking services to NPI and received customary
fees for such services. These services included being lead manager on NPI's
initial public offering in June 1994, a follow-on offering in November 1994,
and a follow-on offering in February 2000.

In the ordinary course of its business, Lehman Brothers may actively trade
in the debt or equity securities of NPI for its own account and for the
accounts of its customers and, accordingly, may at any time hold a long or
short position in such securities.

Interests of Certain NPI Persons in the Merger

Certain NPI executive officers are parties to an executive retention plan
pursuant to which the merger constitutes a change of control and according to
which such officers are, upon the closing of the merger, entitled to a minimum
bonus that is a combination of cash and vested stock options. The ratio of cash
to vested stock is determined by subtracting the amount of an officer's in the
money stock from the total minimum bonus payable to the officer under the
executive retention plan. The executive retention plan entitles such officers
to a minimum bonus ranging from $250,000 to $1,000,000. The executive retention
plan is creditable against all other compensation payable to an officer upon a
change of control of NPI. However, the executive retention plan operates
independently from any compensation payable to an officer upon termination
after a change of control.

In addition, following the closing of the merger, if the combined company
terminates the employment of any of these executive officers pursuant to the
terms of their respective agreements, certain officers are entitled to
severance pay and benefits for a specified period. In general, each executive
officer's severance pay is for a period of six months at the officer's then
current base salary. Certain officers are entitled to continued employment with
NPI as non-officers for a severance period, generally one year, and are
entitled to continued medical coverage under NPI's standard employee medical
insurance coverage and continued benefits under NPI's vacation, holiday and
business expense reimbursement policies for their respective severance periods.

Glenn Penisten, chairman of the board of directors of NPI and an employee of
NPI, owns 17,500 shares of FalconStor Series B preferred stock.

Interests of Certain FalconStor Persons in the Merger

Under the merger agreement, NPI has agreed to honor any indemnification
provisions of FalconStor's certificate of incorporation and bylaws for a period
of six years from the completion of the merger. NPI has also agreed to provide
for indemnification provisions in the certificate of incorporation and bylaws
of the surviving corporation of the merger. In addition, NPI has agreed to
provide director and officer liability insurance for claims arising under the
merger agreement for a period of not less than six years following the
completion of the merger.

The chairman of the board of FalconStor is a member of a "group," as defined
by the Securities Exchange Act of 1934, that is the largest beneficial owner of
NPI common stock.

Treatment of NPI Stock Options and Restricted Stock

NPI's equity plans include the 1994 Outside Directors Stock Option Plan, as
amended, the 1993 Stock Option Plan, as amended, the 1996 Nonstatutory Stock
Option Plan, the 1997 Stock Plan, as amended, and the 1999 Stock Plan, as
amended. The merger qualifies as a "change of control" or "transfer of control"
of NPI under certain of its employee stock plans. The following is a
description of the potential effect of the merger on those plans:

. All options held by employees, directors or consultants under the various
stock option plans will remain outstanding but the vesting of certain
options will accelerate as a result of the transfer of control.

. 1994 Outside Directors Stock Option Plan provides that, in the event of a
transfer of control, any unexercisable or unvested portion of the
outstanding options shall be immediately exercisable and vested in full
as of the date 10 days prior to the date of the transfer of control.

. The NPI board of directors has adopted resolutions that extend the
exercise period of directors' options to one year following termination.

. See "Interests of Certain NPI Persons in the Merger" on page 45.

Treatment of FalconStor Stock Options

All outstanding options shall remain subject to the terms and conditions of
the existing FalconStor stock option plan, including any restrictions on the
exercisability of each option will continue in full force and effect, and the
term, exercisability, vesting schedule and other provisions of each option will
remain unchanged, except that:

. each option will be exercisable for that number of whole shares of NPI
common stock equal to the product of the number of shares of FalconStor
common stock that would be issuable upon exercise of the option
immediately prior to the effective time of the merger multiplied by the
exchange ratio;

. adjustments to incentive stock options may be required pursuant to U.S.
federal tax laws.

Under the terms of the merger agreement, NPI has agreed to assume all
FalconStor options, whether vested or unvested.

Board Composition

Upon the closing of the merger:

. NPI's board of directors will consist of four directors with one vacancy;

. four existing directors, James Regel, Thomas Brown, Michael Gardner, and
Charles Hart, will resign; and

. Barry Rubenstein, ReiJane Huai and Irwin Lieber will be appointed to the
NPI board.

At the closing, the NPI board will be Glenn Penisten, Barry Rubenstein,
ReiJane Huai and Irwin Lieber.

Employee Matters

Pursuant to the merger agreement, NPI has agreed to honor FalconStor's
obligations under all employee benefit plans and employment arrangements that
are disclosed to NPI in connection with the merger. However, the combined
company will maintain the right to amend any such plans in accordance with the
terms thereof. After the effective time, FalconStor employees may become
employees of the combined company at its sole discretion. Each employee's
service with FalconStor prior to the merger may be counted for purposes of
determining periods of eligibility to participate or to vest in the benefit
plans offered by the combined company. In addition, NPI has agreed that the
merger will constitute a change of control with respect to any NPI management
agreements and all payments due thereunder shall be paid after the expiration
of the payee's lock-up agreement. See "Interests of Certain NPI Persons in the
Merger" on page 45.

Structure of the Merger

Each share of FalconStor preferred stock outstanding immediately prior to
the closing, other than preferred stock held by NPI, will be converted
immediately prior to the closing into FalconStor common stock. At the closing
of the merger, Empire Acquisition Corp., a wholly-owned subsidiary of NPI, will
merge with and into FalconStor whereupon the separate corporate existence of
Empire Acquisition Corp. shall cease to exist and FalconStor will be the
surviving corporation. Thus, as a result of the merger, FalconStor will be a
wholly-owned subsidiary of NPI. Each share of FalconStor common stock will be
converted into the right to receive shares of NPI common stock based on the
exchange ratio set forth in the merger agreement.

Material Federal Income Tax Consequences of the Merger

The following is a discussion of the material federal income tax
considerations relevant to the exchange of shares of FalconStor common stock
for NPI common stock pursuant to the merger that are generally applicable to
you. This discussion assumes that you hold your shares as capital assets for
investment. This discussion is based on currently existing provisions of the
Internal Revenue Code of 1986, as amended, the existing and proposed Treasury
Regulations promulgated under the Code, current administrative rulings and
court decisions, all of which are subject to change. Any such change, which may
or may not be retroactive, could materially affect the conclusions expressed
herein. You should also be aware that the following discussion does not deal
with all U.S. federal income tax consequences that may result from the merger
and does not deal with all U.S. federal income tax considerations that may be
relevant to particular stockholders in light of their particular circumstances,
such as stockholders, if any, who are dealers in securities, banks, insurance
companies, tax-exempt organizations, or are foreign persons, stockholders who
acquired their stock through stock option or stock purchase plans or in other
compensatory transactions, or who hold their stock as part of an integrated
investment (including a "straddle") comprised of shares of stock and one or
more other positions, or stockholders who have entered into a constructive sale
of their stock under the constructive sale provisions of the Code.

No ruling from the Internal Revenue Service, or IRS, is being requested
concerning the federal income tax consequences of the merger. The obligations
of the parties to the merger agreement are conditioned on the receipt by
FalconStor of an opinion from its counsel, Olshan Grundman Frome Rosenzweig &
Wolosky LLP, and on the receipt by NPI of an opinion from its counsel, Gray
Cary Ware & Freidenrich LLP, to the effect that the merger will constitute a
reorganization within the meaning of Section 368(a) of the Code. The opinions
of Olshan Grundman and Gray Cary will be subject to limitations and
qualifications and will be based on representations made by FalconStor and NPI.
None of the opinions, nor the tax consequences set forth in the following
discussion, are binding on the IRS or the courts and no assurance can be given
that contrary positions may not be successfully asserted by the IRS or adopted
by a court.

The following discussion does not address the tax consequences of
transactions effectuated prior to, at the time of, or after the merger (whether
or not such transactions are in connection with the merger), including, without
limitation, the exercise of options, warrants or similar rights to purchase
stock, or the exchange, assumption or substitution of options, warrants or
similar rights to purchase FalconStor stock for rights to purchase NPI common
stock. The discussion below assumes that the amount received in the merger with
respect to each share of FalconStor common stock is approximately equal to the
fair market value thereof. Accordingly, you are urged and expected to consult
your own tax advisor as to the specific tax consequences to you of the merger,
including the applicable federal, state, local and foreign tax consequences and
applicable tax return reporting requirements.

Federal Income Tax Consequences of the Merger to FalconStor Stockholders

The tax discussion set forth below is included for general information only.
It is not intended to be, nor should it be construed to be, legal or tax advice
to any particular stockholder. The merger is intended to

constitute a tax-free "reorganization" within the meaning of Section 368(a) of
the Code. If the merger qualifies as a reorganization, you will have the
following federal income tax consequences:

(a) You will recognize no gain or loss based solely upon your receipt of
NPI common stock in exchange for FalconStor common stock in the merger
(except to the extent of cash received in lieu of a fractional share of
FalconStor common stock).

(b) A holder of FalconStor common stock who receives cash in lieu of a
fractional share of NPI common stock will be treated as if the fractional
share had been issued in the merger and then had been redeemed for cash. If
you receive cash in lieu of a fractional share, you will recognize gain or
loss measured by the difference (if any) between the amount of cash
received and your tax basis in such fractional share.

(c) The aggregate tax basis of the NPI common stock you receive in the
merger will be the same as the aggregate tax basis of your FalconStor
common stock surrendered in the exchange.

(d) The holding period of the NPI common stock you receive in the merger
will include the period during which the FalconStor common stock
surrendered in the exchange for the NPI common stock was considered to be
held.

(e) If you exercise your appraisal or dissenters' rights with respect to
a share of FalconStor common stock and receive payment for such stock in
cash, you will recognize capital gain or loss measured by the difference
between the amount of cash received and your adjusted tax basis in such
share, provided such payment is neither essentially equivalent to a
dividend within the meaning of Section 302 of the Code nor has the effect
of a distribution of a dividend within the meaning of Section 356(a)(2) of
the Code (together, a dividend equivalent transaction). A sale of your
FalconStor shares incident to an exercise of appraisal rights will
generally not be a dividend equivalent transaction if, as a result of such
exercise, you own no shares of NPI common stock (either actually or
constructively within the meaning of Section 318 of the Code).

A successful IRS challenge to the tax-free reorganization status of the
merger could result in FalconStor stockholders recognizing substantial taxable
gain or loss with respect to each share of common stock of FalconStor
surrendered. This gain or loss would be measured by the difference between (i)
the sum of the value of the NPI common stock received by FalconStor
stockholders and any cash received in lieu of a fractional share of NPI common
stock, and (ii) the adjusted tax basis in the shares of FalconStor common
stock surrendered. In such event, the aggregate tax basis in the NPI common
stock received by the FalconStor stockholders would equal its fair market
value and the holding period of such stock would begin on the date following
the merger.

Federal Income Tax Consequences of the Merger to NPI Stockholders

NPI stockholders will not recognize any gain or loss as a result of the
merger.

Federal Income Tax Consequences of the Merger to the Companies

The merger will not result in taxable income for any of FalconStor, NPI and
Empire Acquisition Corp.

The preceding discussion does not purport to be a complete analysis or
discussion of all potential tax effects relevant to the merger. Again, you are
urged to consult your own tax advisor as to the specific consequences of the
merger to you, including tax return reporting requirements, the applicability
and effect of federal, state, local, and other tax laws, including the effects
of any proposed changes in the tax laws, and your obligation to retain
information regarding the transaction.

Anticipated Accounting Treatment of the Merger

The business combination will be accounted for under the purchase method of
accounting. Although NPI will be acquiring FalconStor, after the transaction,
FalconStor stockholders will hold a majority of the voting interests in the
combined company. Accordingly, for accounting purposes, the acquisition will be
a "reverse acquisition" and FalconStor will be the "accounting acquiror." As
FalconStor will be the accounting acquiror, its accounts will be recorded at
historical cost and the assets and liabilities of NPI will be recorded at their
estimated fair value as of the closing date.

Intangible assets of approximately $23,500,000 are expected to be recorded
with respect to the business combination, and will be amortized over a period
of three years following the closing of the business combination; however,
because the number of shares to be exchanged in the business combination is
subject to change based on an exchange ratio formula, the final determination
of the purchase price will not occur until the closing of the merger, and will
be based upon the fair market value of NPI's common stock on that date. The
amount of the purchase price allocated to intangible assets, including
goodwill, may fluctuate significantly as a result.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

The following unaudited pro forma condensed combined financial statements
are presented to illustrate the effects of the merger on the historical
financial position and operating results of FalconStor and NPI. The pro forma
statements were prepared as if the merger had been completed as of January 1,
2000 for statement of operations purposes and as of March 31, 2001 for balance
sheet purposes. The pro forma statements have been derived from, and should be
read in conjunction with, the historical financial statements, including the
notes thereto, of each of FalconStor and NPI included in this joint proxy
statement/prospectus. For NPI, those financial statements are also included in
NPI's Quarterly Report on Form 10-Q for the quarter ended March 31, 2001, and
its Annual Report on Form 10-K for the fiscal year ended December 31, 2000.

The pro forma statements include adjustments, which are based upon
preliminary estimates, to reflect the allocation of purchase consideration to
the acquired assets and liabilities of NPI, before any integration or
restructuring adjustments. The final allocation of the purchase consideration
will be determined after the completion of the merger and will be based on
appraisals and a comprehensive final evaluation of the fair value of NPI's
tangible assets acquired, liabilities assumed, identifiable intangible assets
and goodwill at the time of the merger. The final determination of tangible and
intangible assets may result in depreciation and amortization expense that is
different than the preliminary estimates of these amounts.

The pro forma statements are provided for illustrative purposes only and do
not purport to represent what the actual consolidated results of operations or
the consolidated financial position of FalconStor would have been had the
merger occurred on the dates assumed, nor are they necessarily indicative of
future consolidated results of operations or financial position.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

1. BASIS OF PRO FORMA PRESENTATION

On May 7, 2001, NPI announced its agreement to merge with FalconStor in a
transaction to be accounted for as a purchase. Under the terms of the merger,
the number of shares of NPI common stock to be exchanged for each share of
outstanding FalconStor capital stock at the closing date of the merger will be
determined two days prior to the NPI Annual Meeting, as defined. In addition,
NPI assumed all outstanding FalconStor options. Although NPI will be acquiring
FalconStor, after the transaction, FalconStor stockholders will hold a majority
of the voting interests in the combined company. Accordingly, for accounting
purposes, the acquisition will be a "reverse acquisition" and FalconStor will
be the accounting acquiror. As FalconStor will be the accounting acquiror, its
accounts will be recorded at historical cost and the assets and liabilities of
NPI will be recorded at their estimated fair value as of the closing date.

The estimated purchase price is based on NPI common stock and options
outstanding at March 31, 2001. The actual purchase price will be based on the
actual shares of NPI common stock and options outstanding on the closing date.
The market price per share of NPI common stock of $7.76 was the closing market
price as of May 4, 2001, the date NPI and FalconStor entered into the merger
agreement. The actual market price to be applied will be determined based on
the average closing market price at and around the date the exchange ratio is
fixed. The value of outstanding NPI options was estimated by applying the
Black-Scholes valuation model.

The purchase consideration is estimated as follows (in thousands):

Common stock....................................................... $100,000
Assumption of options.............................................. 17,000
Estimated transaction costs........................................ 5,000
--------
Total consideration............................................... $122,000
========

The purchase price allocation is estimated as follows (in thousands):

Tangible assets acquired........................................... $101,806
Goodwill and other intangible assets............................... 23,496
Deferred compensation related to unvested options.................. 280
Liabilities assumed................................................ (3,582)
--------
Total consideration............................................... $122,000
========

2. PRO FORMA ADJUSTMENTS

The pro forma statements give effect to the allocation of the total purchase
consideration to the assets and liabilities of NPI based on their respective
estimated fair values and to the amortization of intangible assets at their
fair values over the respective useful lives. The following pro forma
adjustments have been made to the Unaudited Pro Forma Condensed Combined
Financial Statements:

(A) To record goodwill and other intangible assets of $23,496,000; however,
because the number of shares to be exchanged in the business combination is
subject to change based on an exchange ratio formula, the final
determination of the purchase price will not occur until the closing of the
merger, and will be based upon the fair market value of NPI's common stock
on that date. The amount of the purchase price allocated to intangible
assets, including goodwill, may fluctuate significantly as a result.

(B) To record merger related expenses of $5,000,000. Merger related expenses
include fees for financial advisors, legal advisors and accountants,
printing costs, registration and transfer fees, and other nominal charges.

(C) To eliminate NPI historical stockholders' equity, record the purchase
consideration of $117,000,000 and reduce stockholders' equity for deferred
compensation of $280,000. The pro forma combined stockholders' equity,
after appropriate reclassifications, comprises the following (in
thousands):

Common stock....................................................... $ 46
Additional paid-in capital......................................... 127,150
Deferred compensation.............................................. (280)
Deficit accumulated during the development stage................... (4,792)
Accumulated other comprehensive loss............................... (16)
--------
Total stockholders' equity....................................... $122,108
========

(D) To record deferred compensation charges related to the unvested options
assumed in the merger.

(E) To record the amortization of goodwill and other identifiable intangible
assets related to the merger as if the transaction occurred on January 1,
2000. Goodwill and other intangible assets are expected to be amortized
over three years.

(F) Shares used to calculate pro forma basic and diluted loss per share were
determined by adding approximately 30,100,000 unrestricted shares assumed
to be issued (or 67% of NPI) in exchange for the outstanding FalconStor
shares to NPI's weighted average shares outstanding. Shares used to
calculate pro forma diluted earnings per share excluded the anti-dilutive
effects of NPI's stock options.

Regulatory Filings and Approvals Required to Complete the Merger

The merger is subject to the requirements of the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, which prevents specified transactions from being
completed until required information and materials are furnished to the
Antitrust Division of the Department of Justice and the Federal Trade
Commission and specified waiting periods are terminated or expire. NPI and
FalconStor filed on , 2001 the required information and
materials to notify the Department of Justice and the Federal Trade Commission
of the merger, as amended. The waiting period will expire on ,
2001 unless extended by a request for additional information. If the Federal
Trade Commission issues a request for additional information and documentary
materials, such request extends the waiting period until the date that is 20
days after the companies have substantially complied with the request, although
the Federal Trade Commission may terminate the waiting period at any time after
it has completed its review.

The Federal Trade Commission may challenge the merger on antitrust grounds,
either before or after expiration of the waiting period. Additionally, at any
time before or after the completion of the merger, any state could take action
under the antitrust laws as it deems necessary or desirable in the public
interest, or other persons could take action under the antitrust laws,
including seeking to enjoin the merger. We cannot assure you that a challenge
to the merger will not be made or that, if a challenge is made, we will
prevail.

NPI and FalconStor conduct operations in a number of foreign countries, some
of which have voluntary or mandatory pre-merger or post-merger notification
systems for transactions that satisfy certain thresholds. FalconStor intends to
provide the requisite notification in all foreign jurisdictions in which a
failure to do so would likely have a material effect on the merger or on the
combined company following the merger, or where the filing would otherwise be
in the best interests of the combined company following the merger.

Registration and Listing of NPI Common Stock

NPI common stock is currently listed on The Nasdaq National Market under the
symbol, "NPIX." This joint proxy statement/prospectus is part of a NPI
registration statement on Form S-4 to register under the Securities Act the
shares of NPI common stock to be issued as consideration in the merger. NPI has
agreed to list the shares of NPI common stock to be issued in connection with
the merger on The Nasdaq National Market prior to the closing date of the
merger. After the merger, NPI's name be will changed to FalconStor Software,
Inc. and will change the symbol under which its common stock is traded to " ."

Restrictions on Resale of NPI Common Stock

The shares of NPI common stock to be issued to FalconStor stockholders in
the merger will be registered under the Securities Act. All shares of NPI
common stock received by the officers, directors and stockholders of FalconStor
in the merger will be subject to certain restrictions pursuant to a lock-up
agreement each such individual will enter into with NPI. A form of the lock-up
agreement is attached to this joint proxy statement/prospectus as Annex D.
Under the lock-up agreements, these parties agree not to sell, transfer or
otherwise dispose of the shares of NPI common stock they receive in the merger
for a period of one year following the effective date of the merger. Following
the merger, the board of directors of the combined company may, in its sole
discretion, release any or all of the shares from the lock-up restrictions. The
merger agreement requires FalconStor to cause each officer and director of
FalconStor to execute a lock-up agreement prior to the effective date of the
merger.

All shares of NPI common stock held by any officer, director or employee
stockholder of more than 30,000 shares of NPI common stock shall be subject to
certain restrictions pursuant to a lock-up agreement each such party will enter
into with FalconStor. A form of the lock-up agreement is attached to this joint
proxy statement/prospectus as Annex D. Under the lock-up agreements, such
parties agree not to sell, transfer or otherwise dispose of the shares of NPI
common stock they hold for a period of 365 days following the effective date of
the merger. Following the merger, the board of directors of NPI may, in its
sole discretion, release any or all of the shares from the lock-up
restrictions. Additionally, if such party is terminated by NPI without cause or
voluntarily resigns for good reason after signing the lock-up agreement, then
the shares of NPI

common stock held by such individual shall be released from the lock-up
restrictions. The merger agreement requires NPI to cause each officer, director
and stockholder who holds more than 30,000 shares of NPI common stock to
execute a lock-up agreement prior to the effective date of the merger.
Currently the only employees of NPI who hold more than 30,000 shares of NPI
common stock are also officers of NPI.

Shares of NPI common stock issued to any person who is or becomes an
affiliate of NPI will also be subject to restrictions on transfer. Persons who
may be deemed to be affiliates include individuals or entities that control,
are controlled by, or are under common control with the combined company and
may include some of their respective officers and directors, as well as their
respective principal stockholders. Affiliates may not sell their shares of NPI
common stock acquired in the merger except pursuant to (1) an effective
registration statement under the Securities Act covering the resale of those
shares, (2) an exemption under paragraph (d) of Rule 145 under the Securities
Act, or (3) any other applicable exemption under the Securities Act.

THE MERGER AGREEMENT

The following is a summary of the material provisions of the merger
agreement between NPI and FalconStor dated as of May 4, 2001. This summary may
not contain all of the information that is important to the stockholders of NPI
and FalconStor and thus this description is qualified in its entirety by
reference to the merger agreement attached as Annex A hereto, which you are
urged to read carefully and in its entirety. This summary is qualified in its
entirety by reference to the full text of the merger agreement.

The Merger

At the closing of the merger, Empire Acquisition Corp., a wholly-owned
subsidiary of NPI, will merge with and into FalconStor. FalconStor will be the
surviving corporation and shall continue to be governed by its certificate of
incorporation and bylaws that are currently in effect and, as a result of the
merger, will become a wholly-owned subsidiary of NPI.

Date of Closing

The merger agreement provides that the merger will close no later than the
third business day following the satisfaction or waiver of each of the
conditions to the merger, including the approval and adoption of the merger
agreement and the approval of the merger by the stockholders of FalconStor and
NPI and the approval of the share issuance in the merger and the amendment to
NPI's restated certificate of incorporation by the stockholders of NPI.

Certificate of Incorporation and Bylaws of NPI

Upon the closing of the merger, the amended and restated certificate of
incorporation of NPI and the bylaws of NPI will remain in full force and
effect; however, Article FIRST of the certificate of incorporation shall be
amended to state that the name of the corporation will be FalconStor Software,
Inc. and Article FOURTH shall be amended to increase the number of authorized
shares of common stock to 100,000,000.

Management of NPI Following the Merger

The merger agreement provides that, upon the closing of the merger, NPI's
board of directors shall consist of one director to be designated by NPI and
three directors to be designated by FalconStor. The officers of the combined
company will be:

Name Positions
---- ---------

Barry Rubenstein................... Chairman of the Board
ReiJane Huai....................... President and Chief Executive Officer
Jacob Ferng, CPA................... Chief Financial Officer
Wai Lam............................ Vice President, Engineering
Wayne Lam.......................... Vice President, Marketing
Wendy Petty........................ Vice President, Sales, North America
Bernard Wu......................... Vice President, Business Development
Eric Chen.......................... Vice President, GM Asia

Conversion of Securities; Adjustment of Exchange Ratio

Upon completion of the merger, each share of FalconStor common stock will be
converted into the right to receive the number of shares of NPI common stock
equal to the exchange ratio set forth below.

E = 2(X + 0) + B-CB [2(X + 0)]
---------------------
Y + V

where E = the exchange ratio

X = all shares of NPI common stock issued and outstanding as of two
days prior to the NPI stockholders meeting

O = all shares of NPI common stock issuable under outstanding, vested,
in-the-money options to purchase such stock as of two days prior to
the NPI stockholders meeting

C = NPI's cash, cash equivalents and short-term investments calculated
in accordance with GAAP minus any estimated cash payments due under
agreements with certain members of NPI's management resulting from
the merger plus $25,000,000, calculated as of the end of the
calendar month immediately prior to the effective time of the
merger, without giving effect to reductions in cash for payment of
transaction expenses related to the merger by NPI prior to the
effective time; provided that for purposes of this formula, this
amount shall not exceed $90,000,000. For purposes of this
paragraph, estimated cash payments due under the management
agreements mentioned immediately above shall be determined (a)
using the closing sales price of one share of NPI common stock on
Nasdaq two days prior to the NPI stockholders' meeting and (b) by
giving effect to any acceleration of vesting of options caused by
the closing of the merger

B = $90,000,000

Y = all outstanding shares of FalconStor common stock (assuming
conversion of all outstanding shares of FalconStor preferred stock
into shares of FalconStor common stock) minus shares of FalconStor
common stock or FalconStor preferred stock owned by NPI or
FalconStor, calculated two days prior to the NPI stockholders'
meeting

V = all shares of FalconStor common stock issuable under outstanding,
vested, in-the-money options or warrants to purchase such stock or
other securities convertible or exchangeable for shares of
FalconStor common stock, calculated two days prior to the NPI
stockholders' meeting

NPI will not issue any fractional shares. Instead of receiving a fractional
share, a FalconStor common stockholder will receive cash equal to the product
of (a) such fractional share multiplied by (b) the reported closing sale price
of NPI common stock at the effective time of the merger.

Assuming that NPI's cash, cash equivalents and short-term investments remain
at $ , as stated in NPI's Form 10-Q for the quarter ended March 31,
2001, and that the trading price of NPI common stock remains at $ , the
closing price at , 2001, the aggregate number of shares of NPI common stock
to be issued to the FalconStor stockholders in the merger would be .
This number of shares would result in FalconStor stockholders owning % of
NPI's outstanding capital stock.

Exchange of Certificates

Promptly after the completion of the merger, an exchange agent will mail a
letter of transmittal and exchange instructions to each holder of record of
FalconStor common stock to be used to surrender and exchange certificates
evidencing shares of FalconStor common stock for certificates evidencing the
shares of NPI common stock (and cash in lieu of any fractional share) to which
such holder has become entitled. After receipt of such transmittal forms, each
holder of certificates formerly representing FalconStor common or preferred
stock will be able to surrender their certificates to the exchange agent, and
each such holder will receive in exchange therefor:

. a certificate or certificates evidencing the number of whole shares of
NPI common stock to which such holder is entitled; and

. any cash which may be payable in lieu of a fractional share of NPI common
stock.

Such transmittal forms will be accompanied by instructions specifying other
details of the exchange. FalconStor stockholders should not send in their
certificates until they receive a letter of transmittal and other transmittal
forms.

After the completion of the merger, each certificate evidencing FalconStor
common stock, until so surrendered and exchanged, will be deemed, for all
purposes, to evidence only the right to receive:

. the number of whole shares of NPI common stock which the holder of such
certificate is entitled to receive; and

. any cash payment in lieu of a fractional share of NPI common stock.

The holder of such unexchanged certificate will not be entitled to receive
any dividends or other distributions payable by the combined company until the
certificate has been exchanged. Subject to applicable laws, such dividends and
distributions, together with any cash payment in lieu of a fractional share of
NPI common stock, will be paid without interest.

merger, and such board of directors determines in good faith after consultation
with legal counsel that in light of this superior offer the board must withdraw
or

modify its recommendation in favor of the merger in order to comply with its
fiduciary obligations to the company's stockholders.

transferee executes a counterpart of the voting agreement and agrees to hold
the securities subject to all of the terms of the voting agreement.

No Solicitation

Each party agrees that from the date of the voting agreement through the
earlier of the date on which the merger agreement is terminated or the merger
becomes effective, it will not, directly or indirectly, solicit, initiate, or
knowingly encourage any inquiry, proposal, or offer from any third person or
negotiate with any third party regarding any acquisition or purchase of NPI or
FalconStor, as the case may be, by a third party and it will cease all existing
discussions and negotiations. Each party further agrees to notify either NPI or
FalconStor, as the case may be, immediately upon receipt of any proposal for,
or inquiry regarding, the purchase of NPI or FalconStor. Prior to the effective
time of the merger, however, NPI has the right to sell its assets related
directly to its Ethernet switching business.

Termination

The voting agreements and the accompanying proxies, and all obligations of
the parties thereunder, shall terminate immediately, without any further action
being required, upon the earlier of the date which the merger agreement is
terminated or the merger becomes effective.

COMPARISON OF RIGHTS OF HOLDERS OF NPI COMMON STOCK AND FALCONSTOR CAPITAL
STOCK

This section of the joint proxy statement/prospectus describes material
differences between the rights of stockholders of NPI common stock and the
rights of stockholders of the FalconStor capital stock. The rights compared
are those found in the respective companies' charter documents and corporate
law provisions for Delaware, which is the state in which both companies are
incorporated. While NPI believes that these descriptions address the material
differences, this summary may not contain all of the information that is
important to stockholders of NPI and FalconStor. NPI and FalconStor
stockholders should read this entire document and the documents referred to in
this summary carefully for a more complete understanding of the differences
between the rights of NPI stockholders, on the one hand, and FalconStor
stockholders, on the other.

Size of the Board

The size of the NPI board is fixed from time to time by resolution of the
board of directors. Currently, there are five directors. There will be four
directors and one vacancy at the time of closing. See "Board Composition"
commencing on page 46.

The size of the FalconStor board is fixed from time to time by resolution
of the board of directors. Currently, there are three directors.

Classification

The NPI board is divided into three classes, with each class serving a
staggered three-year term.

The FalconStor board of directors is not classified. Each director is up
for election every year.

Removal of Directors

The NPI certificate of incorporation provides that directors may be removed
with or without cause by the majority vote of all the outstanding shares
entitled to vote in an election of directors.

Any FalconStor director or the entire board may be removed, with or without
cause, by holders of the majority of the capital stock entitled to vote in any
election of directors, voting together as a single class, subject to the
rights of the holders of any class or series of preferred stock.

Vacancies

The NPI bylaws provide that vacancies may be filled either by a majority of
directors in office or at a special meeting of stockholders held for that
purpose.

The FalconStor bylaws provide that vacancies may only be filled by a
majority of the remaining directors.

Limitation on Director Liability

The NPI certificate of incorporation precludes a director's liability for
monetary damages unless the director:

. breaches the duty of loyalty to the corporation or its stockholders;

. commits acts that are not in good faith or which involve intentional
misconduct or a knowing violation of the law;

. pays an illegal dividend or makes an illegal stock purchase; or

. receives an improper personal benefit from a transaction.

The FalconStor certificate of incorporation eliminates a director's
personal liability for breach of fiduciary duty as a director to the fullest
extent allowed under Delaware law.

Indemnification of Directors and Officers

Both NPI and FalconStor indemnify their directors and officers to the
fullest extent allowed under Delaware law.

Amendments to Certificate of Incorporation

The NPI certificate of incorporation requires the affirmative vote of at
least two-thirds of the then outstanding shares in order to amend or repeal
certain provisions of the certificate of incorporation, including those
relating to:

. the conduct of the business and the affairs of NPI;

. the number and election of directors;

. the amendment of NPI's bylaws and certificate of incorporation; and

. the limitations on personal liability for the directors.

The FalconStor certificate of incorporation requires the affirmative vote of
at least a majority of the outstanding voting power of the common stock and
preferred stock, voting together as a single class, in order to amend or repeal
any provision of the certificate of incorporation and a majority of the
outstanding shares of Series A preferred stock, two-thirds of the outstanding
shares of Series B preferred stock, or a majority of the outstanding shares of
Series C preferred stock in order to amend certain provisions of the
certificate of incorporation, including any amendment that adversely affects
the relevant series of preferred stock.

Amendments to Bylaws

The NPI board of directors has authority to amend the bylaws. NPI
stockholders may also amend the bylaws, but only by a two-thirds vote of the
then outstanding shares voting together as a single class.

The FalconStor board of directors has authority to amend the bylaws by a
majority vote. Stockholders may also amend the bylaws upon the affirmative vote
of at least a majority of the outstanding shares of Series A preferred stock,
two-thirds of the outstanding shares of Series B preferred stock, or a majority
of the outstanding shares of Series C preferred stock, if any amendment
adversely affects the relevant series of preferred stock.

Authorized Capital Stock

The NPI certificate of incorporation authorizes the issuance of up to
60,000,000 shares of common stock, par value $.001 per share, and 2,000,000
shares of preferred stock, par value $.001 per share. The NPI board of
directors is authorized, without further action by the stockholders, and
subject to any limitations prescribed by law, to determine, alter or eliminate
any or all of the rights, preferences, privileges and restrictions granted to
or imposed upon any wholly unissued series of preferred shares, and to fix,
increase or decrease the number of shares comprising any such series and the
designation thereof, or any of them, and to provide for the rights and terms of
redemption or conversion of the shares of any such series.

As of , 2001, shares of NPI common stock, and no shares of NPI
preferred stock, were issued and outstanding.

If the merger is approved, the NPI certificate of incorporation will be
amended to authorize the issuance of an additional 40,000,000 shares of common
stock. The total number of shares of NPI common stock that would be authorized
after the merger would be 100,000,000.

The FalconStor certificate of incorporation authorizes the issuance of up to
100,000,000 shares of common stock, par value $0.001 per share, as well as up
to 30,000,000 shares of preferred stock, par value $0.001 per

share. The FalconStor board of directors is authorized, without further action
by the stockholders, and subject to any limitations prescribed by law, to
designate and issue the preferred stock in one or more series, and can fix the
rights, preferences, and privileges of the shares of each series and any
qualifications, limitations, or restrictions on these shares. The FalconStor
board of directors may authorize the issuance of preferred stock with voting or
conversion rights that could adversely affect the voting power or other rights
of the holders of FalconStor's common stock.
As of , 2001, shares of FalconStor common stock and shares of
FalconStor preferred stock (comprised of shares of Series A preferred
stock, shares of Series B preferred stock and shares of Series C
preferred stock) were issued and outstanding.

Dividends

Delaware law provides that the directors of a corporation may declare and
pay dividends on capital stock. Dividends may only be paid out of surplus,
which is the excess of net assets of the corporation over capital, or, if the
corporation does not have adequate surplus, out of net profits for the current
or immediately preceding fiscal year, unless the net assets are less than the
capital of any outstanding preferred stock.

The NPI certificate of incorporation and the FalconStor certificate of
incorporation place no additional restrictions on its board's ability to
declare dividends.

Stock Repurchases, Redemptions, and Conversions

In general, a corporation may not purchase or redeem its own shares if its
capital is impaired or if the purchase or redemption would cause its capital to
be impaired. A company may, however, purchase or redeem preferred shares out of
capital if the shares will then be retired, thereby reducing the capital of the
corporation.

The NPI certificate of incorporation provides that NPI's common stock is not
redeemable.

The FalconStor certificate of incorporation provides that FalconStor may not
redeem or repurchase shares of its common stock or of any other capital stock
of FalconStor ranking junior to any series of preferred stock then outstanding
of FalconStor as to the payment of dividends or the distribution of assets upon
liquidation, dissolution or winding up, unless all declared and unpaid
dividends on such series of preferred stock of FalconStor have been paid.
Holders of a majority of the Series A preferred stock and Series C preferred
stock, and holders of two-thirds of the Series B preferred stock of FalconStor,
when applicable, must consent to the purchase, redemption or acquisition of any
shares of FalconStor's common stock, or of any other capital stock of
FalconStor ranking junior to such series of preferred stock as to the payment
of dividends or the distribution of assets upon liquidation, dissolution or
winding up.

Election of Directors

NPI stockholders and FalconStor stockholders do not have cumulative voting
rights.

Appraisal or Dissenters' Rights

Under the Delaware General Corporation Law, a stockholder of a corporation
participating in certain major corporate transactions may, under varying
circumstances, be entitled to appraisal (or dissenters') rights pursuant to
which such shareholder may receive cash in the amount of the fair market value
of his or her shares in lieu of consideration he or she would otherwise receive
in the transaction. Such rights are not available (a) with respect to the sale,
lease or exchange of all or substantially all of the assets of a corporation,
(b) with respect to a merger or consolidation by a corporation, the shares of
which are either listed on a national securities exchange, such as Nasdaq, or
designated as a national market system security on an interdealer quotation
system by the National Association of Securities Dealers, Inc. or are held of
record by more than 2,000 holders if such stockholders receive only shares of
the surviving corporation or shares of any other

corporation which are either listed on a national securities exchange or
designated as a national market system security on an interdealer quotation
system by the National Association of Securities Dealers, Inc. or held of
record by more than 2,000 holders, plus cash in lieu of fractional shares, or
(c) to stockholders of a corporation surviving a merger if no vote of the
stockholders of the surviving corporation is required to approve the merger
because the merger agreement does not amend the existing certificate of
incorporation, each share of the surviving corporation outstanding prior to the
merger is an identical outstanding or treasury share after the merger, and the
number of shares to be issued in the merger does not exceed 20% of the shares
of the surviving corporation outstanding immediately prior to the merger and if
certain other conditions are met. Because NPI's stock is listed on a national
exchange, NPI stockholders are not entitled to appraisal rights in this merger.
FalconStor stockholders, however, do have appraisal and dissenters' rights. See
"Appraisal or Dissenters' Rights."

Action by Written Consent

The NPI certificate of incorporation prohibits the stockholders from acting
by written consent. All stockholder actions must be taken at a duly called
annual or special meeting.

FalconStor stockholders may act by written consent, provided the written
consent is signed by holders of outstanding stock having not less than the
minimum number of votes that would be necessary to authorize or take such
action at a meeting at which all shares entitled to vote thereon were present
and voted.

Annual Meeting

The annual meetings for both NPI and FalconStor are held on the date and at
the place fixed by their respective boards of directors.

Special Meeting of Stockholders

The NPI bylaws provide that special meetings of the stockholders may only be
called by the board of directors or by the holders of not less than 10% of all
shares entitled to cast voted at the meeting, voting together as a single
class. The meeting shall be held at the time and place designated by the
persons calling the meeting and the business transacted at the special meeting
shall be confined to the purpose or purposes stated in the notice of the
meeting.

The FalconStor bylaws provide that special meetings of FalconStor
stockholders may be called by two or more directors or the chairman of the
board, or by one or more stockholders entitled to cast a majority of the shares
of stock that would be entitled to vote on the proposed matter at the special
meeting. The place of the special meeting shall be fixed by the body or person
calling the special meeting.

Advance Notice Requirements of Stockholder Nominations

In order to nominate an individual for election to the board of directors,
NPI bylaws require a stockholder to provide written notice of the nomination to
the corporation secretary at least 120 days before the first anniversary of the
date written notice of the previous year's meeting was given.

FalconStor's bylaws do not contain any similar provision.

Advance Notice Requirements of Stockholder Business

In order to raise business before the annual meeting, a NPI stockholder must
provide written notice of such intent and a brief description of:

. the issue and why it is to be brought before the meeting;

. the name and address, as they appear on the corporation's books, of the
stockholder proposing such business;

. the number of shares of NPI common stock the stockholder owns; and

. and any material interest the stockholder may have in the matter. The
information must be delivered to NPI's corporate secretary at least 120
days before the first anniversary of the day written notice of the
previous year's meeting was given.

FalconStor's charter documents do not contain comparable provisions.

Rights of Inspection

The certificate of incorporation and the bylaws of NPI do not provide for
inspection rights.
Stockholders of FalconStor may inspect its books and records during normal
business hours as long as such inspection is for a proper purpose, and as long
as the stockholder has made proper written demand stating the purpose of the
inspection. A proper purpose is any purpose reasonably related to the interests
of the inspecting person as a stockholder.

Transactions Between the Corporation and its Directors and Officers

Delaware law provides that a transaction between a corporation and one of
its directors or officers or between the corporation and an entity with which a
director or officer is affiliated shall be valid if:

. the director/officer discloses the material facts to the board of
directors and the transaction is approved by a majority of disinterested
directors; or

. the director/officer discloses the material facts to the shareholders and
the shareholders approve the transaction; or

. the transaction is fundamentally fair to the corporation as of the time
it is authorized, approved, or ratified by the directors or the
shareholders.

The NPI certificate of incorporation and the FalconStor certificate of
incorporation generally track Delaware law.

Stockholders' Rights Plan

Neither NPI nor FalconStor has a stockholders' rights plan.

BUSINESS OF NPI

Provided below is a description of the business of NPI during the fiscal year
ended December 31, 2000.

Overview

NPI designs and sells Fast Ethernet and Ethernet switching solutions for
local area networks, or LANs. All of its switches are based on highly flexible
NuWaveArchitecture, built with its proprietary application-specific integrated
circuits, or ASICs. This architecture is designed to enable NPI to deliver
standards-based switches that can work with a variety of existing LAN
infrastructures and technologies. NPI is directing its sales and marketing
resources evenly toward original equipment manufacturers, or OEMs, and value-
added resellers, or VARs.

As the Internet and complex applications, such as storage area networks, or
SAN, network attached storage, or NAS, enterprise resource planning and data
backup, have become pervasive, the volume of data traffic over LANs has
increased dramatically, often creating bottlenecks on LANs that degrade network
performance. Enterprises have historically implemented Layer 2 switches and
software-based Layer 3 routers to manage increased traffic and to provide the
intelligence necessary to process increasingly complex multi-protocol traffic.
However, increasing bandwidth requirements and transmission speeds combined
with multiple traffic types, such as voice, data and video, have strained the
performance capabilities of software-based Layer 3 routers. In response to
these developments, LAN managers have begun to implement hardware-based Layer 3
switches in their networks to replace both Layer 2 switches and software-based
Layer 3 multi-protocol routers.

Despite the performance improvements of Layer 3 switches versus Layer 3
routers, many of today's Layer 3 switching solutions still have limitations,
such as traffic blocking. NPI addresses this issue and others through its
proprietary NuWaveArchitecture, which enables it to deliver the following
benefits to its customers and end-users:

. High performance at low cost. NPI believes its architecture and modular
design enable it to deliver products with price/performance advantages
regardless of scale or configuration.

. Scalability. NPI's wire-speed, non-blocking Layer 3 switching solutions
enable enterprises to expand their LANs without creating bottlenecks or
impacting network performance. Modular expansion units can connect to
master units via internal high bandwidth channels that do not block
traffic or reduce switching resources.

. Flexibility. NPI's proprietary technology enables it to create new
product configurations using the proprietary ASICs that form the core of
its switches. In addition, NPI's architecture enables it to add software-
based Layer 4-7 capabilities or port third-party software to its switches
to develop new products.

. Manageability. NPI believe its products reduce the complexity of network
management, thereby lowering overall cost of ownership.

NPI initially focused on networking products based on fiber distributed data
interface, or FDDI, technology, and obtained a significant share of the market
for FDDI adapter products in the early 1990s. Because the market for FDDI-based
products declined significantly beginning in 1995, NPI developed a new line of
Layer 2 Fast Ethernet switching products that first shipped in early 1996. By
1998, the market for NPI's FDDI-based products and its Layer 2 Fast Ethernet
products (together, legacy products) declined substantially, and NPI committed
nearly all its resources to the development of a new line of Layer 3 Ethernet
switches founded on its NuWaveArchitecture. NPI commenced limited commercial
shipments of the first product in this line, the Keystone24g in December 1999,
followed by the remainder of the product line in 2000. Because the life cycle
of

its legacy products reached maturity, NPI ceased production of these products
during 2000 in accordance with the decreasing demand and profitability in this
market.

Products and Technology

All of NPI's Ethernet switches are based on NPI's flexible
NuWaveArchitecture, which combines advanced design and proprietary ASICs to
deliver standards-based switches that are intended to work seamlessly with
existing LANs. This architecture offers a 64 Gigabit per second, or Gbps,
crosspoint switching fabric. In addition, the NuWaveArchitecture is designed to
eliminate blocking with multiple input buffers, separate queues for unicast and
multicast traffic and other special queuing and buffering techniques. Further,
NPI's architectural approach gives it the capability to increase functionality
and reduce cost in future generations of NuWaveArchitecture.

Standalone LAN Switching Solutions

Keystone24g. The Keystone24g was the first commercially available Gigabit
Ethernet switch based on NPI's NuWaveArchitecture. It is a fully managed
standalone switch with 24 fixed Fast Ethernet ports and two optional Gigabit
uplinks. The Keystone24g features advanced, traffic-enhancing capabilities,
such as wire-speed IP routing and protocol-based virtual LANs.

Stacking LAN Switching Solutions

Keystone24mg Stack Master. The Keystone24mg Stack Master is a highly
scalable, fully managed Layer 3 switch that supports high capacity Gigabit
Ethernet, Fast Ethernet and WAN interfaces. The Keystone24mg incorporates a
powerful, non-blocking 64-Gbps switching fabric. The Keystone24mg Stack Master
has 24 fixed Fast Ethernet ports and in a stacked environment can provide up to
96 Fast Ethernet ports without blocking. The use of dedicated, separate
channels for user data and management and control information is designed to
ensure wire-speed performance even under sustained periods of high traffic
volume while maintaining network integrity.

Capstone24t Stack Slave. Commercial shipments of NPI's Capstone24t Stack
Slave commenced in the first quarter of 2000. The Capstone24t connects to the
Keystone24mg over an advanced stacking interface that connects the Capstone24t
directly to the Keystone24mg's 64-Gbps switching fabric. The Capstone24t has
24 fixed, full-duplex, auto-negotiating Fast Ethernet ports. One Capstone24t
and one Keystone24mg create a 48-port stack, while a combination of one
Keystone24mg and three Capstone24t switches creates a 96-port stack. Two
optional Gigabit uplinks on the Keystone24mg can expand the stack functionality
and extend price/performance advantages.

Backbone Switching Solutions

Cornerstone Switches. The Cornerstone6g provides up to 12 Gigabit ports and
16 Fast Ethernet ports. The Cornerstone6g is a fully managed standalone switch
that supports high capacity Gigabit Ethernet and Fast Ethernet port
configurations. The base unit has six fixed Gigabit Ethernet ports. Customers
can also choose an additional six Gigabit Ethernet ports and a 16-port Fast
Ethernet option. Gigabit Ethernet ports on the Cornerstone6g are available in
short-haul fiber (SX) and long-haul fiber (LX).

The Cornerstone12g is identical to the Cornerstone6g except that the base
unit has 12 fixed Gigabit ports instead of only six. The same 16-port Faster
Ethernet option card is available on the Cornerstone12g as on the
Cornerstone6g. This combination of port options makes our Cornerstone switches
suitable for a range of high performance applications, including data centers,
network backbones and power workgroups.

Problems encountered with NPI's operating software resulted in unforeseen
delays in commercial shipments, as well as returns, beginning in the second
quarter of 2000. Although NPI believes these problems have been corrected in
subsequent software releases, lost time and expense adversely affected its
operating results and market penetration throughout the year.

Management Software

NuSight GEMS is NPI's Ethernet management software that it bundles and ships
with its NuWaveArchitecture products. The initial version was shipped with
Keystone24g, followed by enhanced versions for each of its NuWaveArchitecture
products as they have been produced. NuSight GEMS provides advanced and easy-
to-use management capabilities that simplify user configuration of NPI's
products as well as diagnostic and management tools. NuSight GEMS is based on
widely accepted industry standards and operates with a variety of management
software applications.

Marketing, Sales and Support

NPI focuses its sales and marketing efforts on OEMs, VARs, system
integrators and distributors. As of December 31, 2000, its worldwide sales and
marketing organization included 38 full-time technically trained marketing,
sales and support personnel located in the United States, the Netherlands and
Taiwan. NPI has domestic sales offices located in Fremont, Los Angeles, Boston,
Chicago and Denver, as well as Reston, Virginia and Sarasota, Florida.

OEMs. NPI is leveraging the flexibility of the NuWaveArchitecture to
integrate its products into OEMs' product lines in traditional LAN markets and
emerging markets such as SAN/NAS, Video, Voice over IP and others. OEMs can
exercise significant influence in the development of its target markets because
they use NPI's products to deliver complete, factory-configured solutions that
are installed and field-serviced by the OEM's technical support organizations.
In 2000, NPI entered into agreements with a number of OEMs to introduce new
products and develop new markets. Its sales personnel, in addition to
traditional marketing and sales functions, are responsible for initiating and
developing relationships with OEM leaders in the computer networking industry.
While NPI does not generally obtain long-term purchase commitments from OEM
customers, NPI enters into contracts with OEM customers to establish the terms
and conditions of sales made pursuant to orders from OEMs. Further, the OEM
customers typically provide NPI with a rolling forecast up to three months in
advance of shipment.

VARs, System Integrators and Distributors. NPI has existing relationships
with a number of distribution channel customers due to its experience with its
legacy products. NPI's technically trained staff is responsible for initiating
and developing relationships with these customers by providing insight into the
evolution of the network environment and facilitating the development and
deployment of optimal network solutions, domestically and internationally.

In 2000, 74% of NPI's sales were in North America, with the balance of the
sales to Asia and Europe representing 15% and 11%, respectively. NPI has
experienced fluctuations in the volume of activity with individual customers
and changes in its customer base and expect such fluctuations and changes to
continue. The loss of a major customer, reductions of a major order or delay in
a major shipment could adversely affect NPI's business and financial
performance.

Research and Development

The successful development and introduction of new products is subject to a
number of uncertainties, including its ability to recruit, train and retain
adequate numbers of professional engineers, successful design of proprietary
ASICs and computer software, design, development and verification testing to
confirm that the products meet NPI's standards for quality, reliability and
interoperability, availability of components, pricing actions by competitors
that may render it unprofitable to introduce the products, unanticipated
technical obstacles or delays, and the emergence or wide acceptance of new
technologies that could render its products obsolete.

NPI works closely with its OEM partners, reseller customers and research
organizations to identify new solutions to meet the current and future needs of
enterprises and Internet service providers. NPI designs its products consistent
with industry standards to ensure interoperability. NPI designed the
NuWaveArchitecture

based on common ASICs and management software to serve as the foundation of all
new models in its product line. This enables NPI to reduce product design and
development cycles providing for fast time to market for new products and
features.

As of December 31, 2000, NPI employed 51 personnel in research and
development, including ASIC design, software development and quality assurance.
NPI also engages third party consultants to expedite development efforts of
certain projects when appropriate. In 2000, NPI's research and development
expenses were $11,200,000.

In October 2000, NPI opened a new software development center at Research
Triangle Park in Durham, North Carolina. This location enables NPI to tap into
the pool of software engineering talent in the Durham area and to extend its
abilities to deliver superior partner and customer care. Software as well as
hardware development will continue to be conducted at its research center in
Bohemia, New York, in close coordination with NPI's new software development
center in North Carolina.

Customer Service and Support and Quality Assurance

NPI's customer service and support organization maintains and supports
products sold by NPI's sales force to end users and provides technical support
to our VARs and OEMs. Generally, our VARs and OEMs provide installation,
maintenance and support services to their customers, and NPI assists them in
providing such support. Questions and problems from end users, VARs and OEMs
can be handled via telephone, e-mail and facsimile. NPI's website is
continually updated to enable its customers to download the latest technical
information and tips, along with firmware, software and product manuals. This
same group also conducts new product Beta testing to ensure that its new
products will meet customer requirements when those products reach the
marketplace.

NPI's quality assurance organization is tied to its customer service and
support organization in order to maintain its focus on satisfaction of customer
requirements and expectations. This group conducts network testing, OEM and
third party testing, problem reproduction and resolution and validation of
manufacturing tools in order to ensure compliance with industry standards,
product performance and interoperability with its customer's existing
equipment.

Manufacturing

NPI's manufacturing operations consist of procurement of components and the
assembly, testing and quality assurance of finished goods for shipment to
customers. NPI purchase the components of its products, including its
proprietary ASICs, circuit boards, integrated circuits and power supplies, from
third parties. NEC is the sole manufacturer of its ASICs. NPI monitors the
quality of the purchased components through quality assurance procedures at its
headquarters in Fremont, California.

In January 2000, NPI entered into an agreement with Solectron Corporation, a
major contract manufacturer with global capabilities, located in Milpitas,
California, to assume all manufacturing responsibilities for NPI. This
arrangement enables NPI to manufacture its products near its North American
customer base and accommodate significant increases in production volume, if
necessary. Under this contract, Solectron purchases the components for NPI's
products and assembles them to NPI's specifications. This further enables NPI
to leverage Solectron's established relationships with suppliers to procure
materials at reduced costs and mitigate potential supply constraints. NPI also
uses Solectron's extensive resources and expertise to assist it in
manufacturing engineering, repair and product testing, and burn-in. NPI
continues to perform all component and supplier qualification, quality
assurance and document control at its facilities.

NPI selects suppliers on the basis of technology, manufacturing capacity,
quality and cost. NPI's agreement with Solectron affords it the opportunity to
have redundant manufacturing locations for each component. Nevertheless, NPI's
reliance on third party suppliers and manufacturers involves risks, including

possible limitations on availability of products due to market abnormalities,
lack of control over delivery schedules, fluctuating manufacturing yields, and
high production costs. The inability of its suppliers to deliver products of
acceptable quality and in a timely manner, or its inability to procure adequate
supplies of its products could have a material adverse effect on NPI's
business, financial condition or operating results.

Competition

The markets in which NPI competes are intensely competitive and are
characterized by frequent new product introductions, changing customer
preferences and evolving technology and industry standards. NPI's competitors
continue to introduce products with improved price/performance characteristics,
and NPI must do the same to remain competitive. Increased competition is likely
to result in significant price reductions and may result in lower than expected
revenues or profit margins, any of which could harm NPI's business, financial
condition or operating results.

Many of NPI's current and potential competitors have significantly broader
product offerings, greater financial, technical, marketing and other resources,
and larger installed bases of customers than NPI does. While the Layer 3
switching market is still in the early stage of development, competition in
this market comes from companies such as Extreme Networks, Foundry Networks,
Nortel Networks, Cisco Systems, 3Com and others. NPI believes that this market
will consolidate over time and that this consolidation could adversely affect
its ability to compete effectively. A number of companies developing
technologies similar to NPI have been acquired by NPI's larger competitors.
These acquisitions are likely to permit NPI's competitors to devote
significantly greater resources to the development and marketing of new
competitive products and the marketing of existing products to their customer
bases. NPI expects that competition will increase as a result of these and
other industry consolidations and alliances. Some of NPI's current and
potential OEM customers could develop products internally that would replace
NPI's products. The resulting lost sales of our products to any such OEMs, in
addition to the increased competition presented by these OEMs, could have a
material adverse effect on NPI's business, financial condition and operating
results.

NPI believes that the principal competitive factors in the LAN equipment
market include the completeness of product offerings, product quality, price
and performance, adherence to industry standards, the degree of
interoperability with other networking equipment and time to market for new
products. NPI believes that NPI competes favorably with respect to each of
these factors.

Intellectual Property

NPI's success is dependent upon its proprietary technology. The core of
NPI's proprietary technology is the NuWaveArchitecture and NPI's ASICs. NPI
relies principally upon copyright, trademark and trade secret laws to protect
its proprietary technology. NPI generally enter into confidentiality or license
agreements with employees, suppliers, customers and potential customers,
limiting or prohibiting their disclosure of NPI proprietary information.
Although NPI holds five U.S. patents covering technology of NPI's legacy
products, NPI does not own any patents or have pending patent applications
associated with NPI's NuWaveArchitecture.

NPI seeks to protect its proprietary rights and other intellectual property
through a combination of copyright, trademark and trade secret protection, as
well as through contractual protections such as proprietary information
agreements and nondisclosure agreements. NPI also believes that factors such as
the technological and creative skills of its personnel, new product
developments, frequent product enhancements and reliable product maintenance
are essential to establishing and maintaining a technology leadership position.

NPI generally enters into confidentiality or license agreements with its
employees, consultants and corporate partners, and generally control access to
and distribution of its software, documentation and other proprietary
information. Despite NPI's efforts to protect NPI's proprietary rights,
unauthorized parties may attempt to copy or otherwise obtain and use NPI's
products or technology. Monitoring unauthorized use of NPI's products is
difficult, and there can be no assurance that the steps taken by it will
prevent misappropriation of NPI's technology, particularly in foreign countries
where the laws may not protect its proprietary rights as fully as do the laws
of the United States.

The following section should be read in conjunction with NPI's consolidated
financial statements and related notes and other financial information included
elsewhere in this joint proxy statement/prospectus. This discussion contains
forward-looking statements that involve risks and uncertainties. NPI's actual
results could differ materially from the results contemplated by these forward-
looking statements as a result of certain factors, including those discussed
below and elsewhere in this joint proxy statement/prospectus, particularly
under the heading, "Risk Factors."

Overview

We were incorporated in California in March 1989 and were reincorporated in
Delaware in 1994. Our initial business focus was on networking products based
on fiber distributed data interface, or FDDI, technology, and we obtained a
significant share of the market for FDDI adapter products in the early 1990s.
Because the market for FDDI-based products declined significantly beginning in
1995, we developed a new line of Layer 2 Fast Ethernet switching products that
we first shipped in early 1996. By 1998, the market for our FDDI-based products
and our Layer 2 Fast Ethernet products (together, our legacy products) declined
substantially, and we committed nearly all of our resources to the development
of a new line of Layer 3 Gigabit Ethernet switches (together, our NuWave
products) founded on our NuWaveArchitecture, which combines our advanced design
and our proprietary application-specific integrated circuits, or ASICs. We
commenced limited commercial shipments of our first NuWave product in December
1999 and volume shipments of all NuWave products in 2000.

Cost of revenue is comprised principally of payments to our materials
suppliers and contract manufacturers, final assembly costs, costs associated
with manufacturing and quality functions, inventory management costs and
certain other product costs. Our gross profit has been affected by many
factors, including:

. declines in the average selling price of our products;

. fluctuations in demand for our products;

. the volume of products sold;

. the mix of products sold;

. the mix of sales channels through which our products are sold;

. new product introductions both by us and our competitors; and

. provision for inventory reserves for potential excess inventories.

Generally, we realize higher margins on sales to the reseller channel than
on sales to OEMs. Any change in the mix between the channels or the loss of a
major customer could adversely affect our gross margin, operating results and
financial condition. We experienced significant erosion in the average selling
prices of our legacy products, and the average selling prices of our NuWave
products have also decreased from their levels at introduction.

In transitioning from our legacy business to our NuWave business, we
incurred significant losses in the past four years primarily reflecting
declining revenues of legacy products in conjunction with substantial
investments in research and development to bring NuWave products to market. The
losses continued through the first quarter of 2001 due to a recent slowdown in
the economy, the failure of our NuWave products to achieve significant market
penetration and continuing high levels of research and development expenses.

On March 30, 2001, we entered into a series of related agreements with
FalconStor, pursuant to which we purchased 9,792,401 shares of FalconStor's
Series C preferred stock for an aggregate price of $25,000,000, and

obtained an exclusive option to merge with FalconStor. On May 4, 2001, we
exercised the option to merge with FalconStor and entered into a merger
agreement with FalconStor. See more details of this transaction in Notes to
Consolidated Financial Statements. In connection with this merger, our board of
directors has approved a proposal to reposition the company as an emerging
leader in network storage infrastructure software and discontinue all of our
existing NuWave and legacy businesses. As such, we are currently seeking
potential buyers for our NuWave business, including the related technology,
inventories and equipment. However, there can be no assurance that we can
successfully secure a buyer for our NuWave business. Furthermore, the
announcement of the merger with FalconStor and our exit from the NuWave
business may cause delay in product purchases by our customers and may also
adversely affect the average selling prices of our NuWave products. Although we
have adopted and announced our plan to discontinue our existing NuWave and
legacy businesses, we have not yet determined the method of disposal, and the
estimated gain or loss may vary significantly depending on the ultimate method
selected. Accordingly, we have not presented the NuWave and legacy businesses
as discontinued operations because our plan is not sufficiently developed to
permit the determination of the gain or loss with sufficiently reasonable
accuracy.

Results of Operations for the Three Months Ended March 31, 2001 and 2000

Net Sales

Net sales for the three months ended March 31, 2001 (the quarter) were $2
million, compared to $3.3 million for the three months ended March 31, 2000
(the comparable quarter). The decrease in net sales was primarily attributed to
an overall slowdown in the economy, resulting in delayed spending on
communication infrastructure by most enterprises and a significant build-up of
capital equipment inventories in the marketplace and, consequently, causing our
OEM and reseller customers to postpone their purchases. In addition, the
decrease in net sales was partially due to the winding down of the legacy
business.

Net sales to OEM customers were $1.2 million for the quarter, which
decreased from $1.8 million for the comparable quarter. Net sales to the
reseller channel decreased to $779,000 for the quarter from $1.5 million for
the comparable quarter. Following a similar downward trend, net sales to North
America and international customers were $1.4 million and $601,000 for the
quarter, compared to $2.2 million and $1.1 million for the comparable quarter,
respectively.

Gross Profit (Loss)

We had a negative gross margin for the quarter, compared to a 24% gross
margin for the comparable quarter. The negative gross margin for the quarter
was primarily attributed to a charge of $4.5 million to provide additional
reserves for potential excess inventories as a result of adverse business
conditions described above.

Research and Development

Research and development expenses were $3.8 million for the quarter,
compared to $2.4 million for the comparable quarter. The increase in research
and development expenses was primarily attributed to the hiring of additional
engineers throughout 2000 and increased spending in professional fees related
to enhancing existing NuWave products and developing new ASICs and products.

Marketing and Selling

Marketing and selling expenses were $3.1 million for the quarter, compared
to $2.0 million for the comparable quarter. The increase in marketing and
selling expenses was primarily attributed to the hiring of additional sales
personnel across the U.S. and increased spending in advertising, trade shows
and other marketing activities, in an effort to penetrate the reseller channel
and seek additional OEM customers.

General and Administrative

General and administrative expenses were $1.3 million for the quarter,
compared to $1.0 million for the comparable quarter. The increase in general
and administrative expenses was primarily attributed to increased spending in
investor relations, recruiting activities and information technology related
services. In addition, we incurred higher insurance expenses as a result of an
overall tightening of the liability insurance market.

Merger Related Expenses

In connection with the investment in and the proposed merger with
FalconStor, we incurred $1.1 million of merger related expenses, primarily
related to legal, accounting and investment banking services specifically
provided for this transaction during the quarter.

Interest Income

Interest income for the quarter was $1.4 million, compared to $779,000 for
the comparable quarter. Such increase in interest income was due to a higher
average balance of cash, cash equivalents and short-term investments throughout
the quarter, compared to the comparable quarter during which the net proceeds
of $165 million from the follow-on public offering were received in early March
2000.

Income Taxes

We did not record a tax benefit associated with the net loss incurred, as
the realization of deferred tax assets is deemed uncertain based on evidence
currently available. Accordingly, a full valuation allowance against deferred
tax assets has been provided.

Results of Operations for the Years Ended December 31, 2000, 1999 and 1998

Net Sales

Net sales were $7.5, $10.2 and $28.6 million in 2000, 1999 and 1998,
respectively. The decrease in net sales was primarily attributed to the winding
down of the legacy business throughout 1999 and 2000, as the demand for our
legacy products experienced rapid decline. The decrease in net sales in 2000
was partially offset by volume shipments of NuWave products started in early
2000.

During the second quarter of 2000, the software used in our NuWave products
displayed instability in certain network environments. This software
instability problem caused delay in shipments and product acceptance testing,
reduced orders from customers in the second quarter and negatively impacted our
customer demand in the third quarter and, to a lesser extent, the fourth
quarter of 2000. Consequently, total net sales in 2000 were substantially lower
than originally estimated.

We believe that the software instability issue we experienced during the
second quarter of 2000 has been resolved. However, software and hardware errors
may occur from time to time in new or enhanced products after commencement of
commercial shipments. These potential problems may adversely affect our future
operating results by causing delays in recognition of revenue and causing us to
incur significant warranty and repair costs, diverting the attention of our
engineering personnel from our product development efforts and causing delay or
loss of market acceptance of our products.

Net sales to OEM customers decreased to $4.8 million in 2000 from $5.2 and
$19.4 million in 1999 and 1998, respectively. Net sales to the reseller
channel, following the same trend, decreased to $2.7 million in 2000 from $5.0
and $9.2 million in 1999 and 1998, respectively. Net sales to customers in
North America were $5.6, $5.7 and $19.7 million in 2000, 1999 and 1998,
respectively. The balance of net sales of $1.9, $4.5 and $8.9 million in 2000,
1999 and 1998, respectively, were to Asia and Europe.

Gross Profit/Margin

We had a negative gross margin in 2000, compared to 8% and 40% in 1999 and
1998, respectively. The negative gross margin in 2000 was primarily attributed
to the lower than expected sales volume and a one-time charge of $1.5 million
to provide reserves for potential excess inventory. We expect our gross margin
in the future periods to improve from the current level to the extent sales
volume increases. The decrease in gross margin in 1999 compared to 1998
primarily reflected the competitive pricing pressures on the Fast Ethernet
products as this market reached the commodity stage. In addition, the decline
in production volume of all legacy products resulted in under-utilization of
our manufacturing facilities and excess overhead charges.

Research and Development

Research and development expenses were $11.2, $7.8 and $11.5 million in
2000, 1999 and 1998, respectively. The increase in research and development
expenses in 2000 compared to 1999 was primarily due to the hiring of additional
engineers and increased spending in professional fees and prototype expenses
related to enhancing existing products based on the NuWaveArchitecture and
developing new products and technologies. The decrease in research and
development expenses in 1999 from 1998 primarily reflected reduction in
compensation, overhead costs and project costs associated with the termination
of legacy product development, including the divestiture of our research and
development office in Taiwan in June 1999.

Marketing and Selling

Marketing and selling expenses were $10.7, $6.4 and $6.0 million in 2000,
1999 and 1998, respectively. The increase in marketing and selling expenses in
2000 compared to 1999 was primarily due to increased spending in advertising,
trade shows and other marketing activities in conjunction with the launch of
NuWave products. In addition, during the second half of 2000, we rapidly
expanded our sales organization by adding sales personnel across the U.S., in
order to effectively penetrate the reseller channel and seek additional OEM
customers. Beginning in the latter part of 1998 and continuing throughout 1999,
we added staff to the sales and marketing group, including technicians and
senior management, and launched advertising campaigns to draw OEM interest,
which was reflected in the increased spending in 1999 compared to 1998.

General and Administrative

General and administrative expenses were $4.7, $3.5 and $3.2 million in
2000, 1999 and 1998, respectively. The increase in general and administrative
expenses in 2000 compared to 1999 was primarily attributed to increased
professional fees incurred for recruiting activities, investor relations and
information technology related services. In addition, we incurred higher
insurance expenses starting the fourth quarter of 2000 as a result of an
overall tightening of the liability insurance market. In 1999, we incurred
higher professional fees, which was the primary factor resulting in increased
expenses in 1999 compared to 1998. These professional fees included the
engagement of an investor relations firm and increased fees paid to information
system consultants to prepare our systems for year 2000 issues.

Restructuring

In August 2000, we approved and announced a plan to divest our manufacturing
facility in Taiwan. Solectron, our contract manufacturer, has agreed to
manufacture all of our products after the divestiture. The objective of this
divestiture is to reduce manufacturing overhead and improve gross margins by
utilizing Solectron's advantages in materials procurement and production
capacity. The divestiture plan consisted of terminating 57 employees in the
manufacturing and the general and administrative functions, selling
manufacturing equipment and closing the manufacturing facility. These actions
resulted in a restructuring expense of $600,000, which included $550,000 for
severance and $50,000 for facility related charges. As of December 31, 2000, we
have paid $410,000 in total for severance and facility related charges. We
completed the divestiture in the first quarter of 2001.

Loss (gain) on Sale of Assets

During the fourth quarter of 2000, we recorded a net loss on sale of assets
of $620,000 in connection with the closure of the manufacturing facility in
Taiwan discussed above. In June 1999, we completed the sale of our research and
development facilities in Hsin-chu, Taiwan, and recorded a gain of $1,055,000,
net of payments of broker fees and severance of $216,000. We divested this
research and development facility to reduce our investment in the legacy
products and to focus our resources on the commercialization of NuWave
products.

Interest Income

Interest income was $7.3 million in 2000, compared to $908,000 and $1.5
million in 1999 and 1998. The increase in interest income in 2000 was due to a
net increase in the aggregate balance of cash, cash equivalents and short-term
investments, of which approximately $165 million was received in March 2000
from our follow-on public offering. The decrease in interest income in 1999
from 1998 was primarily due to the declining balance of cash, cash equivalents
and short-term investments throughout 1999 and 1998.

Income Taxes

We did not record a tax benefit associated with the net loss incurred in
2000, 1999 and 1998, as we deemed that it was more likely than not that the
deferred tax assets will not be realized based on evidence available and,
accordingly, a full valuation allowance was provided. During 1998, we received
an income tax refund of $4 million as a result of the carryback claim of the
1997 net operating loss to offset net income recognized in 1995 and 1994. The
related tax benefit was fully recognized in 1997.

Euro Conversion

We have a wholly-owned subsidiary in the Netherlands, which is one of the 11
European countries participating in the adoption of a common currency, the
Euro, on January 1, 1999. Following the introduction of the Euro, the legacy
currency in each participating country remains as legal tender until January 1,
2002. During the transition period, either the Euro or the legacy currency may
be used to pay for goods and services. Beginning January 1, 2002, participating
countries will issue new Euro-denominated bills and coins, and the legacy
currency will no longer be the legal tender for any transactions after July 1,
2002.

Our subsidiary in the Netherlands is a sales office for the entire European
region. Sales made to all European countries are denominated in US dollars.
Expenses incurred by this subsidiary are currently paid in guilders, the legacy
currency. Sales to all European customers accounted for 11%, 14% and 10% of our
total sales in 2000, 1999 and 1998, respectively; and 6% of our total operating
expenses in 2000, 1999 and 1998 were attributed to this subsidiary. Due to the
immateriality of expenses of the Netherlands subsidiary relative to our
operations as a whole, we believe the Euro conversion will not have any
significant impact to our results of operations during and after the transition
period.

Liquidity and Capital Resources

The aggregate balance of cash, cash equivalents and short-term investments
was $87.6 million at March 31, 2001, compared to $96 million at December 31,
2000. The decrease of $8.4 million was primarily due to the use of cash in
financing our operations, capital expenditures and the repurchase of our common
stock.

Net cash used in operating activities for the quarter was $7.4 million,
which was primarily attributed to our net loss of $12.3 million and decreases
in accounts payable and accrued liabilities of $1.2 million in total, partially
offset by depreciation and amortization of $723,000 and decreases in accounts
receivable, inventories and other assets of $6.1 million in total. Our capital
expenditures totaled $602,000 for the quarter, primarily related to purchases
of test equipment and related software for research and development activities.

In 2000, our board of directors approved a common stock repurchase program,
pursuant to which we are authorized to repurchase up to five million shares of
our common stock. As of March 31, 2001, we have repurchased 3,595,000 shares of
our common stock with a total purchase price of approximately $54.5 million.

Net cash used in operating activities in 2000 was $26.0 million, which was
primarily attributed to our net loss of $22.2 million and increases in accounts
receivable and inventories of $1.1 million and $6.8 million, respectively,
partially offset by depreciation and amortization of $2.5 million and increases
in accounts payable and accrued liabilities of $1.9 million in total. We expect
negative cash flows from operations to continue until we realize operating
income. In 1999, net cash used in operating activities was $13.7 million, which
was principally attributed to the net loss of $15.0 million, partially offset
by a decrease in accounts receivable of $3 million.

Our capital expenditures totaled $3.8 million in 2000, which included
approximately $640,000 of leasehold improvements and furniture and fixtures
added to the new research and development facility in Long Island, New York.
The relocation to this new research and development facility was completed in
November 2000. The balance of the capital expenditures in 2000 was primarily
related to purchases of test equipment and related software for research and
development activities. In 1999, capital expenditures totaled $2.6 million, of
which approximately $650,000 was related to capital expenditures for the
corporate headquarters in Fremont, California.

On April 2, 2001, we paid FalconStor $25,000,000 to purchase 9,792,401
shares of FalconStor's Series C preferred stock at a price of $2.553 per share,
and, on May 4, 2001, we entered into a merger agreement with FalconStor. In
connection with the merger, we engaged an investment bank to explore strategic
alternatives for our NuWave and legacy businesses, which may include selling
our NuWave technology and its related inventories and equipment, terminating
some or all employees, office leases and contracts with certain vendors,
including Solectron, our contract manufacturer. We expect to incur additional
merger related expenses, such as legal, accounting, financial advisor and
printing fees. Although we have adopted and announced our plan to discontinue
our existing NuWave and legacy businesses, we have not yet determined the
method of disposal, and the estimated gain or loss may vary significantly
depending on the ultimate method selected. Accordingly, we have not presented
the NuWave and legacy businesses as discontinued operations because our plan is
not sufficiently developed to permit the determination of the gain or loss with
sufficiently reasonable accuracy.

Our principal sources of liquidity are our cash, cash equivalents and short-
term investments that are expected to be used for general corporate purposes,
including expansion of operations and capital expenditures. We may also use
these capital resources to acquire or invest in businesses, technologies,
products or services that are complementary to our business. From time to time
we have discussed potential strategic acquisitions and investments in third
parties. Other than as disclosed in this joint proxy statement/prospectus, we
currently have no agreements or commitments regarding any acquisitions or
investments. In addition to our cash, cash equivalents and short-term
investments, we also have a $5.0 million revolving bank line of credit, which
expires on June 1, 2001, and is renewable on an annual basis. Borrowings under
the line of credit bear interest at the bank's prime rate. There were no
borrowings under the line of credit as of March 31, 2001.

We believe that our current balance of cash, cash equivalents and short-term
investments will be sufficient to satisfy our working capital and capital
expenditure requirements for at least the next 12 months.

Recent Accounting Pronouncement

In June 1998, the FASB issued Statement of Financial Accounting Standards
(SFAS) No. 133, "Accounting for Derivative and Hedging Activities." SFAS No.
133 establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments embedded in other contracts, and for
hedging activities. SFAS No. 133 requires an entity to recognize all
derivatives as either assets or liabilities on the balance sheet and measure
those instruments at fair value. In June 2000, SFAS No. 133 was amended by SFAS
No. 138, which amended or modified certain issues discussed in SFAS No. 133. We
adopted SFAS

No. 133 and SFAS No. 138 during the quarter ending March 31, 2001. To date, we
have not engaged in derivative or hedging activities. The adoption of SFAS No.
133 and SFAS No. 138 did not have any material impact on our results of
operations or financial condition.

Quantitative and Qualitative Disclosures about Market Risk

Our cash equivalents and short-term investments are exposed to financial
market risk due to fluctuations in interest rates, which may affect the
interest income and the fair values of our investments. We manage the exposure
to financial market risk by performing ongoing evaluation of our investments
and investing in short-term, high quality debt securities, of which the
majority mature within 12 months. In addition, we do not use investments for
trading or other speculative purposes. As of December 31, 2000, the average
rate of return on the investments was approximately 6.4%. A hypothetical 10%
fluctuation in interest rates would change the interest income by approximately
$614,000 per annum. In addition, due to the relative short maturities of our
investments as of December 31, 2000, we expect that the impact of fluctuations
in interest rates on the fair values of investments is immaterial. However,
from time to time, we may adjust the average maturity of our investments, in
order to maximize the rate of return on investments considering the overall
market condition, as well as when our liquidity requirement changes. Such
adjustment to the average maturity may affect the magnitude of the fluctuation
in the fair value of our investments in the event interest rates increase or
decrease.

Industry Background

Rapid Growth of Enterprise Data and Development of Storage Management
Solutions

The rapid growth of data-intensive business applications has increased the
amount of mission-critical enterprise data and, consequently, the need for
dedicated storage. Enterprises are frequently discovering that their existing
storage infrastructure has become inefficient and unable to address evolving
storage requirements. Business enterprises have historically attempted to
support and manage data requirements by directly attaching storage devices to
the individual servers on a local area network, or LAN. Servers communicate in
this direct attached environment using the small computer systems interface, or
SCSI. The SCSI protocol, however, has several drawbacks, including a short
transport distance and an inability to support more than a limited number of
connections. According to IDC, an industry research firm, advances in
technology increased LAN transmission speeds by 100 times during the 1990's,
while storage-to-server data transmission speeds utilizing the SCSI interface
have increased less than 20 times during this period. The result has been
significant congestion at the point of communication between storage systems
and servers.

In order to address these increased storage needs, enterprises are deploying
large RAID devices that are capable of handling multiple Terabytes, or TB (one
trillion bytes), of data. According to Gartner Dataquest, an industry research
firm, average desktop consumption of storage space has grown from 1.4
Gigabytes, or GB (one billion bytes), in 1997 to 3.5 GB in 1999 and is
projected to reach 14.0 GB in 2003. For corporate data centers, the global
storage capacity of RAID devices is expected to grow to 1,300,000 TB by 2003 at
a compounded annual growth rate of 79%. This growth in data storage capacity
has been driven by a number of factors including:

. the rapid expansion of data intensive applications such as e-mail, data
mining and enterprise resource planning;

. the increase in complexity of enterprise computing environments and use
of multiple, incompatible servers and operating systems;

. the need to store redundant copies of enterprise data for business;

. the increase in the number of users accessing computer networks;

. the rapid growth of web hosting, digital video and other multimedia
applications; and

. the decline in the cost of storage (on a per bit basis) as a result of
advances in storage technology.

Accordingly, storage network management has become increasingly more complex
and costly, reflecting the shortcomings and inefficiencies of existing storage
architectures. A locally-attached storage system requires that the storage
devices be managed individually at each server. Also, backup must be done
locally at each server, resulting in high hardware, software and management
costs. Alternatively, it is possible to deploy a single, central backup server
that uses a software agent at each individual server to move data over the
local area network, or LAN, and into the central storage device. However, this
backup process causes network congestion on the LAN, and thus is only performed
during off-peak business hours. Many enterprises operate continuously, which
makes this type of backup procedure impractical. In addition, other servers
cannot share storage space available locally to one server. The space
requirements of various application servers are unpredictable and often cause
IT professionals to over-estimate the amount of storage space required.
Constantly over-estimating storage requirements can be expensive. However,
increasing the amount of data storage space of a particular server that has run
out of storage space is labor intensive and causes service interruption.

Storage area networks, or SAN, and network-attached storage, or NAS, are two
solutions that allow enterprises to reorganize a storage system into a
separately managed storage farm and server farm. The separation of the storage
and server farms creates a more efficient storage network and eventually leads
to a reduction of overall network management complexity. However, SAN and NAS
solutions are two distinct approaches to storage management and address two
separate storage needs.

A NAS appliance is a storage device with a built-in network interface,
network operating system, and storage allocation software. A NAS applicance can
be connected directly to the corporate LAN, making itself accessible through
the use of standard file transport protocols. Users and groups are assigned
read/write privileges and space quota. As the number of users grows, and as
free space becomes low, additional NAS appliance can be plugged in. NAS
simplifies how storage is allocated among clients, however, it does not address
enterprises' need for data backup. Enterprises are still required to run data
backup procedures from a central backup server or to perform backup procedures
unconventionally, such as using proprietary software supplied by the NAS
vendor. Using additional proprietary software leads to increases in management
overhead. In addition, NAS still does not solve the enterprise customer's need
for rapid and scalable data access.

The most effective solution for data-intensive servers is a SAN. In a SAN,
the storage devices are detached from the server, centralized in a storage
farm, and re-connected to the server through a high-speed path. This
configuration increases the overall speed of the network and works well for
data-intensive application servers.

SAN NAS

--------------------------------------------------------------------------------

Pros: Pros:

. Increased data availability . Lower management costs through simplified
. Increased scalability storage process
. Independent server & storage management .File sharing capabilities across multiple platforms
. Scalable architecture .Allows storage subsystems to connect
. Reduced LAN congestion directly onto the LAN
. Increased data transfer rates
. Any-to-any connectivity
Cons: Cons:

. High cost of installation .Inefficient scalability
. Vendor interoperability .Constrained LAN data transmission speeds
. Separate Fibre Channel infrastructure & .Additional proprietary hardware and software
components
. Security concerns

Some corporate data centers are using Fibre Channel to fill their need for
centralized storage management. In 1992, Fibre Channel emerged as a way to
implement a SAN because it was the only viable gigabit-speed transport at that
time. Fibre Channel protocol is an ideal solution for storage traffic because
it can reliably move large blocks of data at high speeds. Fibre Channel can
efficiently move megabytes of data in a single transaction.

Fibre Channel was designed as a network connection tool and did not address
many storage management issues such as:

. quality-of-service;

. snapshot;

. replication;

. mirroring; and

. virtualized storage.

Fibre Channel is essentially an enhanced transport delivery mechanism among
distant hosts and storage devices. Additionally, there is no way to supervise
the data activities or perform data moving operations from a central location.
This presents a security problem for enterprises that want to control a
particular host's ability to access a particular drive. Fibre Channel SANs are
also subject to proprietary standards that reduce the ability of different
storage devices to communicate with each other. This incompatibility raises the
total cost of a storage network because enterprises often use storage
infrastructure from a single vendor.

Fibre Channel SANs also require additional hardware or software to improve
access control and to provide disk sharing.

Storage appliance makers have also started to make high-end, sophisticated
RAID devices, large cabinets with many drives and virtual volume managers to
divide their storage space into individually addressable virtual drives.
Virtual drives enable the storage space to be shared effectively by many hosts.
However, virtualization is only within one cabinet; it is impossible to
virtualize storage resources across multiple cabinets.

There are many fundamental storage security and connectivity issues that are
not addressed by Fibre Channel SAN that require complicated solutions to
address these inefficiencies. Enterprises have been forced to accept a highly
complex, multi-vendor solution with disjointed management tools, reports, and
maintenance procedures to manage their network storage needs.

Market Opportunity

There is a market opportunity emerging for storage networking infrastructure
software that can address the shortcomings of current solutions. As storage
area networks continue to grow in popularity and complexity, innovative
software products will be required to improve the management and transport of
data within an enterprise. Gartner Group estimates that the overall market for
storage management software will grow from $4.2 billion in 1999 to $14.7
billion in 2004, representing a compounded annual growth rate of 28.5%.

Storage virtualization software addresses many of the shortcomings of
current storage network solutions. This software is used to divide available
storage space into virtual volumes without regard to the physical layout of the
actual storage devices. Virtual volumes are not physical storage devices, and
they can be created, expanded, deleted, moved, and selectively presented,
independent of the storage subsystem on which data is actually stored. Storage
virtualization software will allow enterprises:

. to consolidate small computer systems interface, or SCSI, Fibre Channel
and IP storage devices from multiple vendors into a universally
accessible storage pool;

. to connect heterogeneous servers and storage devices and provide greater
functionality and scalability in network storage environments; and

. to preserve investments in legacy storage devices and facilitate the more
cost effective deployment of SANs from different vendors.

In addition, storage virtualization software will provide a storage
operating system for advanced management applications including snapshot,
remote mirroring, and virtual tape.

The storage management challenge led to the development of NAS and SAN
systems, two innovative ways of addressing the storage problem. These two
storage systems do not compete; both are needed by corporate data centers. NAS
represents a quick and simple solution to add general purpose, shareable,
storage space to users and groups and to some application servers that are not
access-intensive. SAN represents a way to separate the server and storage into
two independently managed systems, thereby simplifying the complexity of the
overall information technology, or IT, infrastructure. Fibre Channel, a high-
speed network connection system, has emerged as a viable means to implement a
SAN. However, a pure Fibre Channel SAN alone does not address all the problems
in the areas of connectivity, storage virtualization and storage services.

In order to realize the full potential benefits of storage networks, storage
infrastructure software must also provide connectivity with existing data
networking protocols such as TCP/IP. Enterprises have made substantial
investments in developing their IP networks, and IT professionals are quite
familiar with this networking technology. Storage transport protocols such as
iSCSI, which is compatible with TCP/IP, are emerging to address the enterprise
requirement for convergence between storage and data network technology. IP
compatibility will allow enterprises to connect Fibre Channel SANs across IP-
based wide area networks, and will allow enterprises to leverage their
knowledge of this technology to lower the cost of storage networks. The Company
believes that a market opportunity exists for an intelligent storage networking
software platform that can provide virtualization coupled with advanced
management applications, unified SAN and NAS access and IP connectivity.

FalconStor's Solution

FalconStor's IPStor, an IP/iSCSI-enabled storage networking infrastructure
software, combines the best features of first-generation SANs, such as high
data availability and performance, with the best features of IP networks, such
as product compatibility, proven standards, familiar technology and network
scalability. FalconStor offers fully interoperable products that allow
enterprises to build their storage networking system, using existing
infrastructure, with high-performance, high-availability, manageability and
scalability. By utilizing the connectivity of IP via Ethernet (Fast and/or
Gigabit), FalconStor's IPStor solution greatly expands the reach of the Fibre
Channel SAN while providing the ability to include NAS file sharing under a
unified

management system and delivering the expected benefits of SAN and NAS without
requiring significant hardware purchases. FalconStor's objective is to leverage
IT departments' familiarity with IP to reduce network management costs and to
allow customers to optimize the benefits from existing storage devices. Linking
servers and storage devices over IP network environments creates the benefits
of having a homogeneous network capable of handling all storage traffic.
FalconStor's IPStor is positioned to take advantage of existing IP
infrastructure but also allows enterprises to utilize Fibre Channel and other
emerging storage industry devices and protocols to deliver a comprehensive
storage solution. In addition, IPStor provides the following features:

. Boundless Virtualization. IPStor virtualizes all storage resources across
device, RAID, vendor/brand, and interface boundaries. Any number of
cabinets and/or drives can form a large virtual drive, and a large RAID
drive can be divided into any number of smaller virtual drives to
facilitate sharing across servers or platforms. This enables multiple
application servers to share a single large RAID subsystem. Current Fibre
Channel storage applications cannot do this.

. Rapid Deployment. IPStor is built on open industry standards to provide
easy consolidation of current storage resources and platform neutrality
across operating systems and storage devices. Preserving data allows for
IPStor's rapid deployment because it eliminates the need to perform
migration tasks involving backing up, reformatting and restoring existing
data. IPStor enables IT departments to leverage their expertise in
designing and managing IP networks to solve the storage access problem.
Since IPStor supports both Fibre Channel devices and SCSI devices without
requiring converter boxes, existing data found on the storage devices can
be preserved.

. Scalable Performance. IPStor's IP-based transport mechanism and device-
independent architecture enable IPStor's performance to scale according
to the speed of the processor, the underlying network, the peripheral
interface and the storage device, which will allow users to take
advantage of technological advancements (e.g., Fibre Channel moving from
1 to 2 GB, Gigabit Ethernet evolving from 1 to 10 GB, SCSI bus
accelerating from 160 to 320 MB/s). IPStor enables enterprises to adapt
to rapid changes within the storage market.

. Centralized Management. IPStor provides a Java-based management console
to enable an administrator to manage physical devices, create/manage
virtual drives, define storage management policies, perform end-to-end
diagnostics, and generate reports. IPStor provides centralized end-to-end
monitoring and diagnostics for the entire storage network so that an IT
professional can efficiently operate and manage a heterogeneous storage
network.

. Enterprise-wide Mirroring/Replication with Snapshot. By leveraging IP and
Fibre Channel connectivity, IPStor can perform volume mirroring and
replication across the SAN, LAN, and wide area network, or WAN. Since
IPStor is optimized for data-movement, the mirroring and replication can
be performed without relying on expensive "intelligent controllers" found
only on high-end storage cabinets. The IPStor server's snapshot
capability allows the replication to be performed with integrity, which
addresses the need for rapid backup of enterprise data that is used by
multiple people.

. Zero-impact Backup and Restore. The IPStor server can run industry-
standard backup software to perform ultra-fast, server-free and LAN-free
backup and disaster recovery with zero impact on the application server.
This is essential in a traditional direct attached storage, or DAS,
architecture.

. High-Availability Configuration. IPStor uses two servers to connect to
the storage devices, providing dual-path connections. Both IPStor servers
can be configured to serve requests from different IPStor SAN clients
(running on the application servers) and verify the operational status of
the other IPStor server. If one IPStor server fails, the other alerts the
network supervisor and assumes the additional workload from the failed
server automatically without operator intervention. This configuration
allows constant access to enterprise data, which is critical to
successful operations.

. Advanced Storage Network Security. IPStor offers key-based authentication
to provide comprehensive data network security and prevent application
servers from accessing unauthorized disk space.

Furthermore, because IPStor offers end-to-end storage services using the
standard IP protocol, any off-the-shelf IPSec compliant VPN products can
be used to provide encryption to ensure end-to-end data security.
Currently, Fibre Channel SANs lack a centralized device that supervises
data movement activities, which presents a security problem for
enterprises that want to control specifically a network user's access to a
particular drive.

. Quality of Service. Since SAN or NAS storage services are provided by the
IP server over the Gigabit Ethernet switch, the IPStor server can be
configured to maintain network traffic flow and prevent an aggressive
server from monopolizing the communications bandwidth.

Business Strategy

FalconStor aims to become a leading IP storage networking infrastructure
software provider to enterprises worldwide. FalconStor strives to achieve this
objective through the following strategies:

. Maintain Leadership in IP Storage Networking Infrastructure
Software. FalconStor strives to play a significant role in creating and
defining the IP storage networking infrastructure software market. The
storage networking infrastructure software market is defined by rapid
change, and FalconStor plans to continue to focus its research and
development efforts to create innovative solutions.

. Increase Market Penetration and Brand Recognition Through Enhanced Sales
and Marketing Efforts. FalconStor plans to increase its sales force and
to promote its brand aggressively by:

. advertising in key business and trade periodicals;

. participating in industry events, conferences and trade shows; and

. targeted promotions and public relations campaigns.

. Expand Internationally. FalconStor recently opened its European
headquarters, and plans to build rapidly its operations capabilities in
Europe. FalconStor also opened headquarters in Asia and believes that it
is developing a strong business presence in the Asia/Pacific Rim.

. Expand Technologies and Capabilities Through Strategic Acquisitions and
Alliances. FalconStor believes that opportunities exist to expand through
acquisitions its technological capabilities, product offerings and
services. When evaluating potential acquisitions, FalconStor will focus
on transactions that enable it to:

. acquire important enabling technology;

. acquire complementary applications;

. realize marketing, sales, customer and technological synergies; or

. add key personnel.

. Seek OEM Relationships with Industry Leaders and Storage Service
Providers. FalconStor intends to establish original equipment
manufacturer partnerships with switch, storage, appliance and operating
system vendors. In addition, FalconStor will seek relationships with
storage service providers to broaden the market for its product. These
relationships will offer storage service providers access to FalconStor's
proprietary technology to improve upon their service offerings and enable
FalconStor to participate in the growing market for outsourced storage
services. In addition, FalconStor's IP-based solution is intended to
simplify the hardware requirements of storage service providers and allow
them to deploy rapidly outsourced storage services for clients without
being subject to distance limitation.

FalconStor's Products

FalconStor products utilize off-the-shelf, industry-standard components such
as Gigabit Ethernet, Fibre Channel/SCSI storage devices and the Linux operating
system to construct IP-based storage networking infrastructure. Under this open
architecture, the storage network consists of the following components:

. IPStor Server. The FalconStor IPStor server software runs on a standard
Linux appliance, which virtualizes the storage devices attached to it
using a Fibre Channel or SCSI interface. The server receives data
input/output requests from remote IPStor SAN Clients over IP, Fibre
Channel, and/or iSCSI, and carries out the operations on the target
device. To support mission-critical computing, IPStor server supports
active cluster configuration for fault tolerance and
mirroring/replication, and snapshot operations for redundancy. An
optional NAS module can be installed to provide IP-connected application
servers or user clients with file level shares.

. IPStor SAN Clients. The IPStor SAN client acts as a virtual SCSI adapter
to enable a network's operating system (e.g., Windows NT 4, Windows 2000,
Linux, Solaris) to access the virtualized SAN storage resources attached
to IPStor server. As the network's operating system accesses the storage
resources, the input/output requests and data are routed to the IPStor
servers using FalconStor's SAN/IPTM transport protocol. SAN/IP is an IP-
based, high performance transport mechanism with windowing and flow
control to ensure end-to-end reliability. FalconStor also plans to
support the emerging iSCSI standard protocol when it becomes available.

. NAS Clients. Since IPStor provides standard SMB/CIFS and NFS file shares,
any Windows/Unix client can access the share (if authorized) on the LAN
via the standard network redirector of the OS. No FalconStor software
driver is necessary at these clients.

. IPStor Java-based Manager Console. A single GUI console provides a system
supervisor with reporting, device discovery, security, SAN/NAS resource
mapping, event notification and end-to-end diagnostics capability.

Research and Development

The storage networking infrastructure software services industry is subject
to rapid technological advancements, changes in customer requirements,
developing industry standards, and regular new product introductions and
enhancements. As a result, FalconStor's success, in part, depends upon its
ability to continue to improve its existing solutions and to develop and
introduce new products at a cost-effective and timely basis. There can be no
assurance that FalconStor will be able to successfully develop new products to
address new customer requirements and technological changes, or that such
products will achieve market acceptance.

FalconStor believes that its continued investment in research and
development is critical to its ability to continue to develop and introduce new
and enhanced products addressing emerging market needs.

FalconStor's research and development staff consisted of 44 employees as of
December 31, 2000. Research and development expenses, primarily consisting of
personnel expenses, were $1,363,668 in 2000. FalconStor anticipates that
research and development expenses will increase in 2001.

Sales, Marketing and Customer Service

FalconStor plans to sell its products primarily through relationships with
original equipment manufacturers, resellers and distributors, and a direct
sales force.

. Original Equipment Manufacturer Relationships. These original equipment
manufacturers will collaborate with FalconStor to integrate FalconStor's
products into their own product offerings or resell FalconStor's products
under their own label.

. Reseller and Distributor Relationships. FalconStor currently plans to
enter into reseller and distributor agreements to help sell its product
in various geographic areas. FalconStor's resellers and distributors will
market the entire IPStor product suite and receive a discount on products
sold.

. Direct Sales Force. FalconStor is currently building a direct sales staff
with responsibilities for pursuing and managing larger customers, as well
as providing support to distributors, resellers and original equipment
manufacturers. FalconStor has been hiring additional salespersons and
expects to continue to do so.

FalconStor's marketing department consists of marketing professionals
dedicated to advertising, public relations, marketing communications, events
and channel partner programs. FalconStor's marketing efforts focus on building
brand recognition and developing leads for the sales force.

A dedicated team of FalconStor professional services people are also
available to hand-hold customers and partners through out the product life
cycle of IPStor deployments. The professional services team includes seasoned
storage architects who can assist in the assessment, planning/design,
deployment, and testing phases of an IPStor deployment project, and a technical
support group for post-deployment assistance and on-going trouble-shooting.

Competition

As the demand for IP-based network storage services increases, more
competitors will enter this high-growth market segment. There is no single
entity that directly competes with FalconStor. Although there are several
companies attempting to fill specific needs for SCSI-IP connectivity, Fibre
Channel-IP connectivity and SAN storage management, these solutions require
their own management platform, thereby potentially increasing overall system
complexity. Currently, FalconStor is the only software-based solution that has
a comprehensive architecture providing SAN, NAS and simplified storage
management in a single, well-managed storage system using standard, off-the-
shelf components. However, some of FalconStor's product capabilities are in
competition with a number of significant players with substantially greater
financial and other resources, including DataCore and StorageApps.
Additionally, Cisco Systems and Nishan Systems both announced IP-based storage
solutions. However, both of these are hardware solutions designed to provide
IP-to-SCSI and/or IP-to-Fibre Channel conversions, thereby giving application
servers the ability to access SCSI or Fibre Channel storage devices.
FalconStor's product provides not only IP-based connectivity to application
servers, but also "storage virtualization' and "storage services' such as high-
availability, mirroring, replication, snapshot, and fast backup/restore
enablers. In fact, both Cisco and Nishan are potential OEM customers to
FalconStor's virtualization and storage services software. There is currently
no other known software company providing all of IP-based connectivity,
virtualization, and storage services. FalconStor believes that the principal
competitive factors affecting its market include product features such as
scalability, data availability, ease of use, price, reliability,
hardware/platform neutrality, customer service and support.

FalconStor's success will depend largely on its ability to generate market
demand and awareness of our IPStor software suite, as well as to develop
additional or enhanced products in a timely manner. FalconStor's success will
also depend on its ability to convince potential partners and customers of the
benefits of its software. FalconStor's future and existing competitors could
introduce products with superior features and existing competitors could
introduce products with superior features, scalability and functionality at
lower prices than its products and could also bundle existing or new products
with other more established products in order to compete with FalconStor.
Increased competition is likely to result in price reductions and reduced gross
margins, which could harm its business.

Intellectual Property

FalconStor's success is dependent upon its proprietary technology.
Currently, the IPStor software suite is the core or our proprietary technology.
FalconStor currently has three pending patent applications and pending
trademark applications related to its IPStor product.

FalconStor seeks to protect its proprietary rights and other intellectual
property through a combination of copyright, trademark and trade secret
protection, as well as through contractual protections such as proprietary

information agreements and nondisclosure agreements. The technological and
creative skills of its personnel, new product developments, frequent product
enhancements and reliable product maintenance are essential to establishing and
maintaining a technology leadership position.

FalconStor generally enters into confidentiality or license agreements with
its key technical employees, officers, consultants and corporate partners, and
generally controls access to and distribution of its software, documentation
and other proprietary information. Despite FalconStor's efforts to protect its
proprietary rights, unauthorized parties may attempt to copy or otherwise
obtain and use its products or technology. Monitoring unauthorized use of its
products is difficult, and there can be no assurance that the steps taken by
FalconStor will prevent misappropriation of its technology, particularly in
foreign countries whose laws may not protect its proprietary rights as fully as
do the laws of the United States.

Properties

FalconStor's principal development center and executive and administrative
offices are located in a 6,721 square-foot leased facility in Melville, New
York. FalconStor also has leased offices for development, sales and marketing
personnel which total an aggregate of approximately 6,200 square feet in Paris,
France; Taipei, Taiwan; and Tokyo, Japan. Initial lease terms range from one to
four years, with multiple renewal options.

Legal Matters

FalconStor is not currently a party to any material litigation. From time to
time, however, FalconStor may be subject to claims and lawsuits arising in the
normal course of business.

Steven Wolosky holds 25,000 shares of Series A preferred stock. Mr. Wolosky
is a member of Olshan Grundman, FalconStor's general legal counsel since
February 2000.

Employees

As of March 31, 2001, FalconStor had 83 full-time employees, including 18 in
sales and marketing, 57 in research and development and eight in general
administration. FalconStor is not subject to any collective bargaining
agreements and believes its employee relations are excellent.

FALCONSTOR'S MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following section should be read in conjunction with FalconStor's
consolidated financial statements and related notes and other financial
information included elsewhere in this joint proxy statement/prospectus. This
discussion contains forward-looking statements that involve risks and
uncertainties. FalconStor's actual results could differ materially from the
results contemplated by these forward-looking statements as a result of certain
factors, including those discussed below and elsewhere in this joint proxy
statement/prospectus, particularly under the heading, "Risk Factors."

Overview

FalconStor was incorporated in Delaware in February 2000 for the purpose of
developing, manufacturing and selling data storage network software. Our unique
open software approach to storage networking enables companies to better
capture and manipulate the expanding volume of enterprise data and existing
storage solutions, without rendering those solutions obsolete. By moving the
intelligence of storage management from hardware to software, we allow
companies to adopt the state-of-the-art Fibre Channel technology while at the
same time, leverage their prior investments in Ethernet information technology
(IT) infrastructure, taking full advantage of the ubiquitous connectivity of
the industry-standard Internet Protocol (IP). Our software technology can
rapidly embrace various input/output (I/O) interface, communications standards
and innovative storage services as they are introduced. Our unique architecture
has been recognized and licensed by partners in Ethernet Switch, SCSI-to-Fibre
Channel Router, Disk-Subsystem and Appliances spaces. Our flagship IPStor
product, which began shipping May 2001, is today the only available all-
software solution that combines industry-standard connectivity with next-
generation network storage services, offering large, distributed enterprises a
complete storage management solution that includes all four of the key service
categories: universal connectivity supporting both Fibre Channel and IP/iSCSI-
based storage provisioning; virtualization; storage services such as fail-over,
mirroring, replication and snapshot; and unified SAN (storage area network) and
NAS (network-attached storage).

In March 2000, we raised $3,000,000 from the issuance of 3,000,000 shares of
Series A preferred stock and raised an additional $7,000,000 in September 2000
from the issuance of 4,900,000 shares of Series B preferred stock. Our
operations since inception were mainly comprised of the development of our core
data storage network software product. During 2000 and the first quarter of
2001, we were in the development stage of operations, as a result there were no
significant revenues generated from our planned principal operations. The
revenues generated in 2000 were from network consulting services.

On March 30, 2001, we entered into a series of related agreements with NPI
pursuant to which NPI purchased 9,792,401 shares of our Series C preferred
stock for an aggregate price of $25,000,000, and obtained an exclusive option
to merge with us. On May 4, 2001, NPI exercised the option and entered into a
merger agreement with us.

Results of Operations for the Three Months Ended March 31, 2001

Since FalconStor did not begin operations until February 10, 2000, there
were no significant activities for the three months ended March 31, 2000. As a
result the following management discussion and analysis does not include
comparisons to prior periods.

Revenues

We did not generate any revenues for the three months ended March 31, 2001
since our software was still in the development process and we did not yet
begin shipping our product. Future revenues are expected to be derived from
software licenses and maintenance fees related to the software.

Cost of Revenues

For the three months ended March 31, 2001 we did not incur any cost of
revenues since we did not begin shipping our product. In the future, cost of
revenues are expected to be mainly comprised of production costs and shipping
costs related to software licenses and personnel costs related to technical
support.

Software Development Costs

Software development costs were $873,534 for the three months ended March
31, 2001 and were mainly comprised of personnel related expenses. Costs
incurred during the quarter were related to the development of our core storage
networking infrastructure software product. Through March 31, 2001, no software
development costs were capitalized. Software development costs are expected to
increase in the future as we continue to modify and enhance our product.

Selling and Marketing

Selling and marketing expenses were approximately $1.1 million for the three
months ended March 31, 2001 and were mainly comprised of personnel costs,
travel and entertainment, public relations expense, trade shows and costs
associated with our sales offices in Taiwan and France. Selling and marketing
expenses are expected to increase in the future as additional sales personnel
are hired and marketing efforts are initiated in order to sell and promote our
software. Additionally, we will incur commission expense, and increased travel
and entertainment and public relation expenses.

General and Administrative

General and administrative expenses were $870,795 for the three months ended
March 31, 2001. These expenses were mainly comprised of personnel costs,
professional fees and rent. General and administrative expenses are expected to
increase in the future to support our overall growth.

Interest Income

Interest income was $78,652 for the three months ended March 31, 2001.
Interest income was earned on cash and cash equivalents, which was raised from
the issuance of Series A and B convertible preferred stock.

Income Taxes

We did not record a tax benefit associated with the pre-tax net loss
incurred from the period from inception (February 10, 2000) through March 31,
2001, as we deemed that it was more likely than not that the deferred tax
assets will not be realized based on our development stage operations and,
accordingly, we provided a full valuation allowance against the deferred tax
asset.

Results of Operations for the Period From Inception (February 10, 2000) Through
December 31, 2000

Since 2000 was our first year of operations, management's discussion and
analysis does not include any comparisons to prior periods.

Services Revenues

Services revenues were $143,294 for the period from inception (February 10,
2000) through December 31, 2000. These revenues were comprised of network
consulting fees, which were billed on a time and materials basis and recognized
as revenue when the services were performed. We do not expect network
consulting fees to comprise a significant percentage of revenues in the future.
Future revenues are expected to be derived from software licenses and
maintenance fees related to the software.

Cost of Revenues

Cost of revenues in 2000 were $209,053 and were comprised of salaries of
personnel working on network consulting contracts. The cost of salaries were
greater than the revenues generated from these contracts, which resulted in a
gross loss for 2000. In the future, cost of revenues are expected to be mainly
comprised of production costs and shipping costs related to software licenses
and personnel costs related to technical support.

Software Development Costs

Software development costs were $1,363,668 in 2000 and were mainly comprised
of personnel related expenses. Costs incurred in 2000 were related to the
development of our core data storage network software product. Through December
31, 2000, no software development costs were capitalized. Software development
costs are expected to increase in the future as we continue to modify and
enhance our product.

Selling and Marketing

Selling and marketing expenses were $326,609 in 2000 and were mainly
comprised of personnel costs. Selling and marketing expenses are expected to
increase in the future as additional sales personnel are hired and marketing
efforts are initiated in order to sell and promote our software. Additionally,
we will incur commission expenses, increased travel and entertainment and
public relation expenses.

General and Administrative

General and administrative expenses were $472,400 for the period from
inception (February 10, 2000) through December 31, 2000. These expenses were
mainly comprised of professional fees and rent. General and administrative
expenses are expected to increase in the future to support our overall growth.

Interest Income

Interest income was $225,551 for the period from inception (February 10,
2000) through December 31, 2000. Interest income was earned on cash and cash
equivalents, which was raised from the issuance of Series A and B preferred
stock.

Income Taxes

We did not record a tax benefit associated with the pre-tax net loss
incurred from the period from inception (February 10, 2000) through December
31, 2000, as we deemed that it was more likely than not that the deferred tax
assets will not be realized based on our development stage operations and,
accordingly, we provided a full valuation allowance against the deferred tax
asset.

Recent Accounting Pronouncement

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 133, Accounting for Derivative
Instruments and Hedging Activities, which is effective for all fiscal quarters
of all fiscal years beginning after June 15, 2000, as amended by SFAS No. 137.
In June 2000, SFAS No. 138 was issued which amended certain provisions of SFAS
No. 133. SFAS No. 133 establishes accounting and reporting standards for
derivative instruments, including certain derivative instruments embedded in
other contracts, and for hedging activities. In accordance with SFAS No. 133,
an entity is required to recognize all derivatives as either assets or
liabilities in the statement of financial position and measure those
instruments at fair value. SFAS No. 133 requires that changes in the
derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met. Special accounting for qualifying hedges
allows a derivative's gains and losses to offset related results on the hedged
item in the

income statement and requires that a company formally document, designate and
assess the effectiveness of transactions that receive hedge accounting. The
implementation of SFAS No. 133 did not have a significant impact on our
consolidated financial statements for the quarter ended March 31, 2001.

Liquidity and Capital Resources

Our cash and cash equivalents at March 31, 2001, was $5,483,685. Between
April 1, 2001 and May 4, 2001 we received an additional $33,150,000 from the
sale of 12,986,079 shares of Series C preferred stock.

Net cash used in operating activities for the period from inception
(February 10, 2000) through March 31, 2001 was approximately $3,500,000, which
was primarily attributed to our net loss of approximately $4,800,000 and
increases in accounts receivable and prepaid expenses and other current assets
totaling $306,625. These amounts were partially offset by depreciation and
amortization, non-cash professional services expense, equity-based compensation
earned and increases in accounts payable, accrued expenses and deferred
revenue, which totaled approximately $1,600,000 in the aggregate.

Net cash used in investing activities for the period from inception
(February 10, 2000) through March 31, 2001 was approximately $1,000,000, which
was related to the purchase of property and equipment of $784,679, and the
payment of a security deposit of $220,099 related to our office space lease.

Net cash provided by financing activities was approximately $10,000,000. We
raised net proceeds of approximately $10,000,000 through the issuance of Series
A and B preferred stock. Additionally, we raised $55,000 through the issuance
of common stock.

Our principal sources of liquidity are cash and cash equivalents, which are
expected to be used for general corporate purposes, including expansion of
operations and capital expenditures.

We believe that our current balance of cash and cash equivalents, along with
the $33,150,000 we received between April 1, 2001 and May 4, 2001, will be
sufficient to satisfy our working capital and capital expenditure requirements
for at least the next 12 months.

NETWORK PERIPHERALS INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. The Company

Network Peripherals Inc., a Delaware corporation (the "Company"), designs
and manufactures Layer 2 and Layer 3 functionality Ethernet and Ethernet
switching products, which it markets primarily to original equipment
manufacturers, distributors, value-added resellers and system integrators. The
Company's switching products are designed for use in workgroups, wiring closets
and network backbones.

As discussed in Notes 13 and 14, on March 30, 2001, the Company entered into
a series of related agreements with FalconStor, Inc. ("FalconStor"), a
privately held company, whereby, among other things, the Company made a $25
million investment in FalconStor, and obtained an exclusive option to merge
with FalconStor. On May 4, 2001, the Company exercised its option and entered
into a merger agreement with FalconStor.

Note 2. Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiaries. All significant intercompany accounts and
transactions have been eliminated.

Interim Consolidated Financial Statements (Unaudited)

The financial information as of March 31, 2001 and for the three months
ended March 31, 2001 and 2000 is unaudited and includes all adjustments,
consisting only of normal recurring adjustments, that management considers
necessary for a fair presentation of the Company's financial condition,
operating results and cash flows as of such date and for such periods. Results
for the three months ended March 31, 2001 are not necessarily indicative of the
results to be expected for the year ending December 31, 2001 or for any future
period.

Use of Estimates

The preparation of financial statements in accordance with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
of assets and liabilities and disclosures of contingent assets and liabilities
at the date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.

Cash, Cash Equivalents and Short-Term Investments

The Company considers all highly liquid investments purchased with an
original or remaining maturity of three months or less to be cash equivalents.
The Company's short-term investments consist of marketable debt securities,
substantially of which have maturities between three months and one year. All
marketable debt securities included in short-term investments have been
classified as available-for-sale and are carried at fair market value, and the
unrealized gains or losses on these investments are included as a separate
component of the stockholders' equity. For the years ended December 31, 1999
and 1998, there were no material unrealized gains or losses on investments.

Concentration of Credit Risk

Financial instruments, which potentially subject the Company to
concentrations of credit risk, consist principally of cash, cash equivalents,
short-term investments and trade receivables. The Company maintains its cash,
cash equivalents and short-term investments with high credit quality financial
institutions and limits its investments to those that are short-term and low
risk. Concentration of credit risk with respect to trade receivables is
generally limited due to the Company's on-going evaluation of its customers'
credit worthiness and the established long-term relationship with certain
customers.

NETWORK PERIPHERALS INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Revenue Recognition

Revenue from product sales is recognized when pervasive evidence of an
arrangement exists, delivery has occurred, the price is fixed or determinable
and collectability is probable. The Company provides to certain distributors
limited rights of return and price protection on unsold inventory when specific
conditions exist. Provisions for estimated costs of warranty repairs, product
returns, and retroactive price adjustments are recorded at the time products
are shipped based on past experience. Allowances for uncollectible accounts
receivable are provided at the time such receivable is deemed uncollectible.

In December 1999, the Securities and Exchange Commissions issued Staff
Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial
Statements." SAB 101 summarizes certain of the Staff's views in applying
generally accepted accounting principles to revenue recognition in financial
statements. The adoption of SAB 101 in the fourth quarter of 2000 did not have
a material effect on the Company's results of operations or financial
condition.

Inventories

Inventories are stated at the lower of cost, using the first-in, first-out
method, or market.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation and
amortization. Depreciation and amortization is computed using the straight-line
method over the estimated useful life of the asset, typically three years.
Depreciation of the Company's enterprise resource planning systems, its
information systems infrastructure, and certain manufacturing equipment is
based on an estimated useful life of five years. Amortization of leasehold
improvements is computed using the remaining lease term.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of
the identifiable net assets acquired and is amortized on a straight-line basis
over the expected period of benefit, generally five years. Periodically, the
Company evaluates the goodwill for impairment and estimates the future
undiscounted cash flows of the acquired business to ensure that the carrying
value has not been impaired. As of December 31, 2000 and 1999, goodwill, net of
accumulated amortization, was $53,000 and $93,000, respectively, and was
included in other assets.

Software Development Costs

The Company's software products are integrated into its hardware products
and are typically available for general release to customers within 30 days
after technological feasibility has been achieved. Accordingly, the production
costs incurred after the establishment of technological feasibility and before
general release to customers are immaterial. The Company has not capitalized
any software development costs to date.

Advertising Costs

The Company expenses all advertising costs as incurred. Advertising costs
totaled $2,293,000, $634,000 and $381,000 in 2000, 1999 and 1998, respectively.

Income Taxes

The Company accounts for income taxes under the asset and liability method,
which recognizes deferred tax assets and liabilities for the expected tax

assets and liabilities and their financial statement reported amounts, and for
net operating loss and credit carryforwards. The Company records a valuation
allowance against deferred tax assets when it is more likely than not that such
assets will not be realized.

Foreign Currency Translation

The functional currency of the Company's subsidiaries in Taiwan and the
Netherlands is the U.S. dollar. Accordingly, gains or losses arising from the
translation of foreign currency financial statements and transactions are
included in determining consolidated results of operations.

Employee Benefit Plans

The Company has stock option plans and offers a 401(k) plan covering all of
its U.S. employees. The 401(k) plan provides for matching contributions
determined at the Company's discretion. The Company matched 50% of each
employee's contribution up to $3,000 in 2000 and $1,000 in 1999. The matching
contributions totaled $202,000 and $59,000 in 2000 and 1999, respectively. No
such matching contributions were made in 1998.

Stock-based Compensation

The Company accounts for stock-based awards to employees using the intrinsic
value method in accordance with Accounting Principles Board ("APB") Opinion No.
25, "Accounting for Stock Issued to Employees", as permitted under the
provisions of Statement of Financial Accounting Standards ("SFAS") No. 123,
"Accounting for Stock-Based Compensation." Under APB Opinion No. 25, if the
exercise price of the Company's employee stock options equals the market price
of the underlying stock on the date of grant, no compensation expense is
recognized.

In March 2000, the Financial Accounting Standards Board ("FASB") issued FASB
Interpretation No. 44 ("FIN 44"), "Accounting for Certain Transactions
involving Stock Compensation." FIN 44 clarifies the application of APB Opinion
No. 25 regarding (a) the definition of employee for purposes of applying APB
Opinion No. 25, (b) the criteria for determining whether a stock option plan
qualifies as a noncompensatory plan, (c) the accounting consequence of various
modifications to the terms of a previously fixed stock option or award, and (d)
the accounting for an exchange of stock compensation awards in a business
combination. FIN 44 became effective on July 1, 2000, but certain conclusions
cover specific events that occurred after either December 15, 1998, or January
12, 2000. The adoption of FIN 44 did not have a material impact on the
Company's results of operations or financial condition.

Net Loss Per Share

Basic earnings per share are computed as net earnings divided by the
weighted-average number of common shares outstanding for the period. Diluted
earnings per share reflects the potential dilution that could occur from common
shares issuable through stock-based compensation including stock options,
restricted stock awards, warrants, and other convertible securities using the
treasury stock method. During 2000, 1999 and 1998, the Company incurred net
losses, such that the inclusion of potential common shares would result in an
antidilutive per share amount. Accordingly, no adjustment is made to the basic
net loss per share to arrive at the diluted net loss per share.

Comprehensive Loss

For the year ended December 31, 2000, the Company's comprehensive loss
included net loss and the change in unrealized gain on investments. There were
no reconciling items between the Company's net loss and comprehensive loss for
the years ended December 31, 1999 and 1998.

Recent Accounting Pronouncement

In June 1998, the FASB issued Statement of Financial Accounting Standards
("SFAS") No. 133, "Accounting for Derivative and Hedging Activities." SFAS No.
133 establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments embedded in other contracts, and for
hedging activities. SFAS No. 133 requires an entity to recognize all
derivatives as either assets or liabilities on the balance sheet and measure
those instruments at fair value. In June 2000, SFAS No. 133 was amended by SFAS
No. 138, which amended or modified certain issues discussed in SFAS No. 133.
The Company will adopt SFAS No. 133 and SFAS No. 138 during the year ending
December 31, 2001. To date, the Company has not engaged in derivative or
hedging activities. The adoption of SFAS No. 133 and SFAS No. 138 will have no
material impact on the Company's results of operations or financial condition.

Treasury Stock

In 2000, the Company's Board of Directors approved a common stock repurchase
program, pursuant to which the Company may repurchase up to five million shares
of its Common Stock in the open market. As of December 31, 2000, the Company

discount through payroll deductions. Prior to the termination of the Employee
Stock Purchase Plan, the Company reserved 250,000 shares of Common Stock for
issuance thereunder, and the Company has issued 223,606 shares of Common Stock
for an aggregate purchase price of $1,434,000.

Stock Option Plans

The Company's 1999 Stock Plan, as amended, (the "1999 Plan") provides for

1993 Stock Option Plan (the "1993 Plan") and the 1996 Nonstatutory Stock Option
Plan (the "1996 Plan"). No further stock options were granted under the 1993
Plan or the 1996 Plan. Outstanding options and shares issued upon the exercise
of options granted continue to be governed by the terms and conditions of the
respective plans. As of December 31, 2000, options to purchase a total of
353,567 shares of Common Stock were outstanding under the 1993 Plan and the
1996 Plan.

The 1994 Outside Directors Stock Option Plan, as amended, (the "1994 Plan")
which provides for the automatic granting of nonqualified stock options to
directors of the Company ("Outside Director"), has a total of 150,000 shares
reserved for issuance. Pursuant to the 1994 Plan, the Company grants to each
new Outside Director an option to purchase 15,000 shares of Common Stock at the
time of their appointment and to each Outside Director an additional option to
purchase 5,000 shares of Common Stock on the date of each annual meeting of
stockholders. The exercise price of the stock options will be the fair market
value of the Common Stock on the date of grant, and options vest over a period
of four years. As of December 31, 2000, options to purchase 70,000 shares of
Common Stock were outstanding, 69,584 shares were available for future grant,
and 139,584 shares of Common Stock were authorized but unissued under the 1994

The Company has elected to continue to follow APB Opinion No. 25 to account
for its employee stock options and adopted the disclosure-only requirements of
SFAS No. 123. SFAS No. 123 requires the disclosure of pro forma net income and
earnings per share as if the Company had accounted for its employee stock
options under the fair value method in accordance with SFAS No. 123. The fair
value of these options is estimated on the date of grant using the Black-
Scholes option-pricing model with the following weighted-average assumptions:
expected volatilities of 110% in 2000, 93% in 1999 and 82% in 1998; risk-free
interest

years in 2000 and 1999 and 2.5 years in 1998; and no dividend yield for all
periods.

Had compensation cost for the Company's employee stock-based plans been
determined based on the fair value at the grant date for awards consistent with
the provisions of SFAS No. 123, the Company's net loss and net loss per share

of approximately $15.5 million, which will expire beginning in 2002.

Note 9. Restructuring

In August 2000, the Company approved and announced a plan to divest its
manufacturing facility in Taiwan. A turnkey manufacturer will manufacture all
of the Company's products after the divestiture. The objective of the
divestiture is to reduce manufacturing overhead and improve gross margins by
taking advantage of the turnkey manufacturer's economies of scale in materials
procurement and production capacity. The divestiture plan consisted of
terminating 57 employees in the manufacturing and the general and
administrative functions, selling manufacturing equipment and closing the
manufacturing facility. These actions resulted in a restructuring expense of
$600,000, which included $550,000 for severance and $50,000 for facility
related charges. The Company completed the divestiture in the first quarter of
2001. The following table summarizes the activities of the accrual for
restructuring expense in 2000 (in thousands):

facility in Taiwan discussed in Note 9 above. In June 1999, the Company sold
its research and development facility located in Hsin Chu, Taiwan, for a total
of $1,620,000, of which $900,000 was received in 1999, and the remaining
balance of $720,000 was received in July 2000. In connection therewith, the
Company recorded a gain of $1,055,000, net of payments of broker fees and
severance of $216,000.

The Company's proprietary ASICs (Application-Specific Integrated Circuits)
are currently manufactured by a single foundry. In addition, subsequent to the
closure of the Company's manufacturing facility in Taiwan in the fourth quarter
of 2000, all of the Company's products are manufactured by one turnkey
manufacturer. In the event that the foundry or the turnkey manufacturer fails
to deliver the expected volumes or meet the required quality standard, the
Company may experience delay in production of its products and loss of
revenues, which could adversely impact the Company's operating results.

Note 13. Subsequent Event

On March 30, 2001, the Company entered into a series of related agreements
with FalconStor, pursuant to which the Company purchased Series C Preferred
Stock of FalconStor having an aggregate purchase price of $25,000,000, and
obtained an exclusive option to merge with FalconStor. FalconStor develops and
markets network storage infrastructure software that enables storage over IP
using standard industry components such as Gigabit Ethernet, Fibre Channel and
SCSI, with planned support for iSCSI and Infiniband. The investment agreements
provide that the Company has the right to designate one member of FalconStor's
board of directors and entitle the Company to liquidation, registration, voting
and preemptive rights customary for venture capital style investments.

The option agreement gives the Company the right to merge with FalconStor.
The form of merger agreement provides that, as consideration for all
outstanding shares of FalconStor's stock, the Company would issue a number of
newly issued shares of its common stock determined in accordance with a
formula. The number of shares issuable in the merger would depend upon a number
of variable factors, including the trading price per share of the Company's
common stock at the time of the merger, the Company's assets at the time of the
merger and other factors. The actual number of shares is expected to result in
the Company's current stockholders having a one-third interest in the combined
entity. In addition, the Company would assume all outstanding options to
acquire shares of FalconStor's common stock, which would result in the
potential issuance of approximately 4,500,000 shares if those options vested
and were exercised. The merger would be structured as a tax free reorganization
and would be accounted for as a purchase. Completion of the merger would be
subject to the expiration of the applicable Hart-Scott-Rodino waiting period,
stockholder approval and other customary closing conditions. In the event that
the Company does not exercise the option, and under certain other
circumstances, the Company may be required to pay FalconStor a penalty of
$3,000,000.

Note 14. Subsequent Event (Unaudited)

On April 2, 2001, the Company paid FalconStor $25,000,000 to purchase
9,792,401 shares of FalconStor's Series C Preferred Stock as discussed in Note
13 above. On May 4, 2001, the Company exercised the option to merge with
FalconStor and entered into a merger agreement with FalconStor. In connection
with the merger, the Company engaged an investment bank to explore strategic
alternatives for its Ethernet Switching business, which may include selling the
Company's NuWave technology and its related inventories and equipment,
terminating some or all employees, office leases and contracts with certain
vendors, including the Company's contract manufacturer. Although the Company
has adopted and announced a plan to discontinue its NuWave and legacy
businesses, the Company has not yet determined the method of disposal, and the
estimated gain or loss may vary significantly depending on the method selected.
Accordingly, the Company has not presented the NuWave and legacy businesses as
discontinued operations because the plan of disposal is not sufficiently
developed to permit the determination of the gain or loss with sufficiently
reasonable accuracy.

During April 2001, as a result of general business conditions and also due
to the pending merger with FalconStor, the Company cancelled substantially all
of its outstanding purchase orders with Solectron, its contract manufacturer.
According to the contract between the Company and Solectron, the Company may be
liable for certain cancellation charges, and such charges could be significant.
The Company has begun discussions with Solectron to resolve this matter;
however, the Company cannot reasonably estimate its liability at this time.

Falconstor, Inc.:

We have audited the accompanying consolidated balance sheet of Falconstor,

and the related consolidated statements of operations, stockholders' equity and
comprehensive loss, and cash flows for the period from inception (February 10,
2000) through December 31, 2000. These consolidated financial statements are
the responsibility of the Company's management. Our responsibility is to
express an opinion on these consolidated financial statements based on our
audit.

We conducted our audit in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Falconstor,
Inc. and subsidiary as of December 31, 2000, and the results of their
operations and their cash flows for the period from inception (February 10,

generally accepted in the United States of America.

FALCONSTOR, INC. AND SUBSIDIARY
(a development stage enterprise)

Notes to Consolidated Financial Statements
December 31, 2000

(1) Summary of Significant Accounting Policies

(a) The Company and Nature of Operations

Falconstor, Inc. (the "Company") was incorporated in Delaware on February
10, 2000 for the purpose of developing, manufacturing and selling storage
networking infrastructure software. The Company also provides network
consulting services in the metropolitan New York area.

As of December 31, 2000, the Company was in the development stage, as
operations from inception through December 31, 2000 consisted primarily of the
development of the Company's core data storage network software product, and no
significant revenues were generated from the Company's planned principal
operations. In April, 2001, the Company completed the development of its
principal product, and anticipates releasing it for sale and commencing the
generation of software license revenue.

(b) Unaudited Interim Financial Information

The unaudited interim financial statements of the Company as of and for the
three months ended March 31, 2001, and the period from inception (February 10,
2000) through March 31, 2000 and the period from inception (February 10, 2000)
through March 31, 2001, included herein have been prepared, without audit,
pursuant to the rules and regulations of the SEC. Certain information and note
disclosures normally included in financial statements prepared in accordance
with generally accepted accounting principles have been condensed or omitted
pursuant to such rules and regulations relating to interim financial
statements.

In the opinion of management, the accompanying unaudited interim financial
statements reflect all adjustments, consisting only of normal recurring
adjustments, necessary to present fairly the financial position of the Company
at March 31, 2001, and the results of its operations and its cash flows for the
three months ended March 31, 2001 and the period from inception (February 10,
2000) through March 31, 2000 and the period from inception (February 10, 2000)
through March 31, 2001.

The accompanying consolidated financial statements include the accounts of
the Company and its wholly-owned subsidiary, Falconstor, Ltd., Taiwan, which
was primarily involved in development activities during 2000. All significant
intercompany transactions and balances have been eliminated in consolidation.

(d) Cash equivalents

The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents. Cash equivalents,
consisting of money market funds, amounted to $7,548,124 at December 31, 2000

(e) Revenue Recognition

The Company recognizes revenue from software licenses in accordance with
Statement of Position ("SOP") 97-2, Software Revenue Recognition. Accordingly,
revenue for non-customized software is recognized when persuasive evidence of
an arrangement exists, the fee is fixed and determinable and the software is
delivered, provided no significant obligations remain and collection of the
resulting receivable is deemed probable. Software delivered to a customer on a
trial basis is not recognized as revenue until a permanent key is delivered to
the customer. Software maintenance fees are deferred and recognized as revenue
ratably over the term of the contract. The cost of providing technical support
is included in cost of revenues. The Company had no revenue from software
licenses or maintenance fees in 2000.

124

FALCONSTOR, INC. AND SUBSIDIARY
(a development stage enterprise)

Notes to Consolidated Financial Statements--(Continued)
December 31, 2000

Network consulting fees, which are billed on a time and materials basis, are
recognized as revenue when the services are performed. Costs of providing these
services are included in cost of revenues.

The Company has entered into various distribution, licensing and joint
promotion agreements with OEM's, whereby the Company has provided the OEM a
non-exclusive software license to install the Company's software on certain
hardware in exchange for royalty payments based on the number of products
distributed by the OEM. Nonrefundable advances received by the Company from an
OEM for software engineering services are recorded as deferred revenue and
recognized as revenue when the services are complete and the software product
master is delivered and accepted. Deferred revenue related to such arrangements
amounted to $133,000 at December 31, 2000.

(f) Property and Equipment

Property and equipment are recorded at cost. Depreciation is recognized
using the straight-line method over the estimated useful lives of the assets (3
to 7 years).

(g) Software Development Costs

Costs associated with the development of new software products and
enhancements to existing software products are expensed as incurred until
technological feasibility of the product has been established. Based on the
Company's product development process, technological feasibility is established
upon completion of a working model. Through December 31, 2000, no software
development costs were capitalized.

(h) Income Taxes

Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary
differences are expected to be realized or settled. The effect on deferred tax
assets and liabilities of a change in tax rates is recognized in income in the
period that includes the enactment date.

(i) Long-Lived Assets

The Company reviews its property and equipment for impairment whenever
events or changes in circumstances indicate that the carrying amount of the
asset may not be recoverable. If the sum of the expected future cash flows,
undiscounted and without interest, is less than the carrying amount of the
asset, an impairment loss is recognized as the amount by which the carrying
amount of the asset exceeds its fair value.

(j) Accounting for Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with SFAS
No. 123, Accounting for Stock-Based Compensation. The Company has elected to
record compensation expense for stock options and warrants granted to employees
and directors only if the then-current market price of the underlying stock
exceeds the exercise price on the date of grant, in accordance with the
provisions of Accounting Principles Board ("APB") Opinion No. 25, Accounting
for Stock Issued to Employees, rather than the fair value based method of
measuring compensation cost under SFAS No. 123. Accordingly, the Company has
disclosed the pro-forma net loss as if the fair value method of SFAS No. 123
had been used to measure compensation cost. Transactions in which options and
warrants are granted to other than employees and directors are accounted for at
fair value.

125

FALCONSTOR, INC. AND SUBSIDIARY
(a development stage enterprise)

Notes to Consolidated Financial Statements--(Continued)
December 31, 2000

(k) Financial Instruments

As of December 31, 2000, the fair value of the Company's financial
instruments including cash and equivalents, accounts receivable, accounts
payable and accrued expenses, approximates book value due to the short maturity
of these instruments.

(l) Stock Split

In July, 2000, the Company's Board of Directors declared a five-for-one
stock split to be effected in the form of a common stock dividend. For purposes
of the accompanying consolidated financial statements, all share and per share
information has been adjusted for the stock split.

(m) Foreign Currency

Assets and liabilities of foreign operations are translated at rates of
exchange at the end of the period, while results of operations are translated
at average exchange rates in effect for the period. Unrealized gains and losses
from the translation of foreign assets and liabilities are classified as a
separate component of stockholders' equity. Realized gains and losses from
foreign currency transactions are included in the statement of operations.

(n) Earnings Per Share (EPS)

Basic EPS is computed based on the weighted average number of shares of
common stock outstanding. Diluted EPS is computed based on the weighted average
number of common shares outstanding increased by dilutive common stock
equivalents. Due to a net loss, all common stock equivalents were excluded from
diluted loss per share. As of December 31, 2000, potentially dilutive common
stock equivalents included 6,559,500 stock options outstanding and 24,800,000
shares issuable upon the conversion of convertible preferred stock.

(o) New Accounting Pronouncement

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 133, Accounting for Derivative
Instruments and Hedging Activities, which is effective for all fiscal quarters
of all fiscal years beginning after June 15, 2000, as amended by SFAS No. 137.
In June 2000, SFAS No. 138 was issued which amended certain provisions of SFAS
No. 133. SFAS No. 133 establishes accounting and reporting standards for
derivative instruments, including certain derivative instruments embedded in
other contracts, and for hedging activities. In accordance with SFAS No. 133,
an entity is required to recognize all derivatives as either assets or
liabilities in the statement of financial position and measure those
instruments at fair value. SFAS No. 133 requires that changes in the
derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met. Special accounting for qualifying hedges
allows a derivative's gains and losses to offset related results on the hedged
item in the income statement and requires that a company formally document,
designate and assess the effectiveness of transactions that receive hedge
accounting. The Company does not believe that the implementation of SFAS No.
133 will have a significant impact on its consolidated financial statements
when adopted on January 1, 2001.

(p) Comprehensive Income (Loss)

Comprehensive income (loss) includes the Company's net income (loss) and
foreign currency translation adjustments and is included the consolidated
statement of stockholders' equity.

FALCONSTOR, INC. AND SUBSIDIARY
(a development stage enterprise)

Notes to Consolidated Financial Statements--(Continued)
December 31, 2000

(q) Use of Estimates

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

(2) Liquidity

As shown in the accompanying financial statements, the Company incurred a
net loss and negative cash flow from operations during the period from
inception (February 10, 2000) through December 31, 2000. Management has
formulated plans that it believes will provide the Company with sufficient
liquidity to meet its cash obligations at least through January 31, 2002. Such
plans include (a) the availability of $7,727,182 in cash and cash equivalents
as of December 31, 2000, (b) the commencement of the marketing of its core data
storage network software, and (c) the receipt by the Company of $25,000,000
from the sale of Series C Preferred Stock (note 9).

(3) Property and Equipment

Property and equipment consist of the following at:

--------- --------
$ 682,378 $583,201
========= ========

(4) Income Taxes

Due to pre-tax losses, there was no provision for Federal, state or foreign
income taxes in 2000. The tax effects of temporary differences that give rise
to the Company's deferred tax assets as of December 31, 2000 are as follows:

Deferred tax assets:
U.S. Net operating loss carryforwards.......................... $485,500

127

FALCONSTOR, INC. AND SUBSIDIARY
(a development stage enterprise)

Notes to Consolidated Financial Statements--(Continued)
December 31, 2000

The difference between the provision for income taxes computed at the
Federal statutory rate and the reported amount of tax expense attributable to
loss before income taxes for the period from inception (February 10, 2000)
through December 31, 2000 is as follows:

Tax recovery at Federal statutory rate......................... $(681,000)
Increase (reduction) in income taxes resulting from:
State and local taxes, net of Federal income tax benefit..... (147,300)
Non-deductible expenses...................................... 34,700
Non-deductible expenses of foreign operations................ 18,400
Increase in valuation allowance.............................. 775,200
---------
$ --
=========

For the period from inception (February 10, 2000) through December 31, 2000,
the Company had a pre-tax loss of $1,951,000 in the U.S. and a pre-tax loss
from foreign operations of $52,000. As of December 31, 2000, the Company has
U.S. net operating loss carryforwards of approximately $1,150,000, which expire
in 2020. At December 31, 2000, the Company has established a valuation
allowance against its net deferred tax assets due to the Company's development
stage losses and the resulting likelihood that the deferred tax asset is not
realizable. The utilization of certain of these tax loss carryforwards may be
subject to annual limitations imposed by the Internal Revenue Code Section 382
due to the Company's various equity transactions which may result in a change
of control.

(5) Stockholders' Equity

Upon the incorporation of the Company on February 10, 2000, the Company
issued 15,000,000 shares of its common stock for proceeds of $30,000.

In November 2000, in connection with a three year consulting agreement, the
Company, in addition to agreeing to pay a monthly consulting fee, sold 100,000
shares of common stock to the consultant for $25,000. The consultant's rights
to such shares will vest for 33,000 on each of November 1, 2001 and 2002 and
34,000 on November 1, 2003. If, prior to November 1, 2003, the consultant
ceases to provide consulting services for any reason, the Company has the right
to repurchase any unvested shares at $0.25 per share. The excess of the fair
value of the common stock over $0.25 will be recorded as consulting expense
each period until the services are performed and the common stock vests.

In March 2000, the Company issued 3,000,000 shares of its Series A
convertible preferred stock ("Series A") at $1.00 per share for net proceeds of
$2,976,329. Each share of Series A is convertible, at the option of the holder,
into five shares of common stock. The Series A will automatically convert into
common stock upon the affirmative vote of the holders of a majority of the
outstanding shares of Series A and upon the closing of a public offering under
certain circumstances. The holders of Series A are entitled to receive
cumulative cash dividends at the same rate as dividends are paid with respect
to the common stock. The Series A is not redeemable at the option of the holder
and has a liquidation preference equal to the greater of $1.00 per share plus
all accumulated unpaid dividends, or the amount that the Series A holders would
have received had they converted all Series A into shares of common stock. The
holders of the Series A are entitled to elect two directors of the Company.

In September 2000, the Company issued 4,900,000 shares of its Series B
convertible preferred stock ("Series B") at $1.43 per share for net proceeds of
$6,997,116. Each share of Series B is convertible, at the

option of the holder, into two shares of common stock. The Series B will
automatically convert into common stock upon the affirmative vote of the
holders of a majority of the outstanding shares of Series B and upon the
closing of a public offering of the Company's common stock under certain
circumstances. The holders of Series B are entitled to receive cumulative cash
dividends at the same rate as dividends are paid with respect to the common
stock. The Series B is not redeemable at the option of the holder and has a
liquidation preference equal to the greater of the amount that the Series B
holders would have received had they converted all Series B into shares of
common stock, or the aggregate purchase price paid for the Series B plus all
accumulated unpaid dividends.

At December 31, 2000 the Company had reserved, authorized and unissued
common shares, for the following purposes:

(6) Stock Options

As of May 1, 2000, the Company adopted the Falconstor, Inc. 2000 Stock
Option Plan (the "Plan"). The Plan is administered by the Board of Directors
and provides for the issuance of stock-based compensation to employees,
consultants and non-employee directors. The maximum number of shares which may
be awarded under the plan is 8,000,000. Options may be incentive ("ISO") or
non-qualified. Exercise prices of ISOs granted must be at least equal to the
fair value of the common stock on the date of grant, and have terms not greater
than ten years, except those to an employee who owns stock greater than 10% of
the voting power of all classes of stock of the Company, in which case they
must (a) have an option price at least 110% of the fair value of the stock, and
(b) expire after five years from the date of grant.

During 2000, the Company granted its employees ISOs to purchase an aggregate
of 6,245,000 shares of common stock at an exercise price of $0.25 per share.
Such options generally vest over a period of three years and are exercisable
for a period of ten years from the date of grant. As of December 31, 2000, no
options were exercisable. No options were exercised or canceled during 2000.

Also during 2000, the Company granted options to certain non-employee
consultants to purchase an aggregate of 274,500 shares of common stock in
exchange for certain professional services received during 2000. These options
have an exercise price of $0.25 per share, vest over a period of three years
and are exercisable for a period of ten years from the date of grant. The
aggregate fair value of these options as determined using the fair value method
under SFAS No. 123, amounting to approximately $52,155, was recorded as general
and administrative expense with a corresponding credit to additional paid-in
capital.

In addition, in November 2000, the Company granted options to certain non-
employee consultants to purchase an aggregate of 40,000 shares of common stock
in exchange for certain professional services which are to be performed during
the period from November 2000 through November 2001. These options have an
exercise price of $0.25 per share, vest over a period of three years and are
exercisable for a period of ten years from the date of grant. The aggregate
fair value of these options as determined using the fair value method under
SFAS No. 123, amounts to approximately $7,600, $1,267 of which was recorded as
general and

129

FALCONSTOR, INC. AND SUBSIDIARY
(a development stage enterprise)

Notes to Consolidated Financial Statements--(Continued)
December 31, 2000

administrative expense during 2000 with a corresponding credit to additional
paid-in capital. The expense related to these options will be adjusted to fair
value until performance of the services has been completed.

The per share weighted average fair value of stock options granted during
the period from inception (February 10, 2000) to December 31, 2000 was $0.14 on
the date of grant using the Black-Scholes option-pricing model with the
following weighted average assumptions: expected dividend yield of 0%, risk
free interest rate of 6%, expected stock volatility of 60% and an expected
option life of five years for options granted to employees of the Company, and
an option life of ten years for options granted to non-employees.

The Company applies the provisions of APB Opinion No. 25 in accounting for
stock-based employee compensation. Had the Company determined stock-based
compensation cost based upon the fair value method under SFAS No. 123, the
Company's pro-forma net loss and diluted net loss per share for the period from
inception (February 10, 2000) through December 31, 2000, would have been
$2,154,172, and $0.14, respectively.

(7) Commitments

The Company has an operating lease covering its primary office facility that
expires in September, 2005. Upon inception of this lease the Company was
required to pay a $201,596 security deposit to the lessor. The Company also has
an operating lease covering its office space in Taiwan that expires in
November, 2001. The following is a schedule of future minimum lease payments
for these operating leases as of December 31, 2000:

Year ending December 31,
------------------------

2001............................................................ $141,791
2002............................................................ 146,831
2003............................................................ 152,072
2004............................................................ 157,523
2005............................................................ 84,146
--------
$682,363
========

These leases require the Company to pay its proportionate share of real
estate taxes and other common charges. Total rent expense for operating leases
was $68,571 for the period from inception (February 10, 2000) through December
31, 2000.

The Company is a party to various claims arising in the ordinary course of
its business, the resolution of none of which, the Company believes will have a
material adverse effect on the Company's liquidity or results of operations.

(8) Subsequent Event

On March 30, 2001, the Company entered into an agreement with Network
Peripherals Inc. ("NPI"), a public company that designs and manufactures
Ethernet switching hardware, whereby on April 2, 2001 the Company issued
9,792,401 shares of its $0.001 par value Series C convertible preferred stock
("Series C") at $2.55 per share to NPI for gross proceeds of $25,000,000. Each
share of Series C is convertible, at the option of the holder, into one share
of common stock. The Series C will automatically convert into common stock upon
the affirmative vote of the holders of a majority of the outstanding shares of
Series C and upon either (i) the closing of a public offering of the Company's
common stock under certain circumstances, or (ii) the

130

FALCONSTOR, INC. AND SUBSIDIARY
(a development stage enterprise)

Notes to Consolidated Financial Statements--(Continued)
December 31, 2000

consummation of a merger or consolidation of the Company with or into another
company. The holders of Series C are entitled to receive cumulative cash
dividends at the same rate as dividends are paid with respect to the common
stock. The Series C is not redeemable at the option of the holder and has a
liquidation preference equal to the greater of $2.55 per share plus all
accumulated unpaid dividends, or the amount that the Series C holders would
have received had they converted all Series C into shares of common stock. The
holders of the Series C are entitled to elect one director of the Company.

In connection with the sale of the Series C, on March 30, 2001 the Company
and NPI entered into an irrevocable option agreement whereby NPI received an
exclusive option to merge with the Company. The option may be exercised through
April 27, 2001, unless extended by written consent of NPI and the Company. The
merger agreement provides that, as consideration for all outstanding shares of
the Company's common stock, NPI would issue a number of newly issued shares of
NPI common stock as determined in accordance with the merger agreement. Based
on the agreement, the number of NPI common shares to be issued would result in
the Company's stockholders having at least a two-thirds ownership in the
combined entity. The merger would be structured as a tax free reorganization,
and would be accounted for as a purchase transaction. Completion of the merger
would be subject to the expiration of the applicable Hart-Scott-Rodino waiting
period, stockholder approval and other customary closing conditions. In the
event that NPI does not exercise the option, and under certain other
circumstances, NPI may be required to pay the Company a penalty of $3,000,000.
There can be no assurance that the merger will be consummated in a timely
manner, if at all.

(10) Subsequent Events (Unaudited)

On May 4, 2001, the Company issued 3,193,678 shares of its Series C at $2.55
per share for gross proceeds of $8,153,460. Also on May 4, 2001, NPI exercised
its option to merge with the Company, and the Company and NPI entered into a
definitive merger agreement.

131

NPI PROPOSAL NO. 2

AMENDMENT OF RESTATED CERTIFICATE OF INCORPORATION

Under Delaware law, NPI may only issue shares of common stock to the extent
such shares have been authorized for issuance under NPI's restated certificate
of incorporation. The restated certificate of incorporation currently
authorizes the issuance by NPI up to 60,000,000 shares of common stock.
However, as of , 2001, shares of NPI common stock were issued
and outstanding and shares of common stock were reserved for issuance
under NPI's stock option plans. Approximately shares of common
stock are proposed to be issued to holders of FalconStor capital stock pursuant
to the merger, and, in addition, approximately shares of NPI common
stock must be reserved effective as of the closing of the merger for options
exercisable for FalconStor common stock assumed by NPI pursuant to the merger
agreement. As a result, without an increase in shares, NPI would not have
sufficient shares available in order to issue the required number of shares in
the merger. The merger agreement provides for the amendment of NPI's restated
certificate of incorporation to increase the number of shares of common stock
authorized for issuance to 100,000,000 shares.

The purpose of the proposed amendment to the restated certificate of
incorporation pursuant to the merger agreement is to authorize additional
shares of common stock which will be available for issuance in the merger, for
a reserve for issuance upon exercise of stock options assumed in the merger,
and also in the event the board of directors determines that it is necessary or
appropriate to issue additional shares in connection with a stock dividend,
additional equity incentives to employees and officers, or for other corporate
purposes. The availability of additional shares of common stock is particularly
important in the event that NPI needs to undertake any of the foregoing actions
on an expedited basis and wishes to avoid the time and expense of seeking
stockholder approval in connection with the contemplated issuance of common
stock. NPI has no present agreement or arrangement to issue any of the
additional authorized shares other than in connection with the merger and the
exercise of options assumed in the merger.

The increase in authorized common stock will not have any immediate effect
on the rights of existing stockholders except the effects of the merger
described in this section. However, the board will have the authority to issue
common stock without requiring future stockholder approval of such issuance,
except as may be required by applicable law. To the extent that additional
shares are issued in the future, they may decrease the existing stockholders'
percentage equity ownership and, depending on the price at which they are
issued, could be dilutive to the existing stockholders.

The increase in the authorized number of shares of common stock and the
subsequent issuance of shares could have the effect of delaying or preventing a
change in control of NPI without further action by the stockholders. Shares of
authorized and unissued common stock could, within the limits imposed by
applicable law, be issued in one or more transactions which make a change in
control of NPI more difficult, and therefore less likely. Any such issuance of
additional stock could have the effect of diluting the earnings per share and
book value per share of outstanding shares of common stock, and such additional
shares could be used to dilute the stock ownership or voting rights of a person
seeking to obtain control of NPI. The board of directors is not currently aware
of any attempt to acquire NPI. While it may be deemed to have potential anti-
takeover effects, the proposed amendment to increase the authorized common
stock is not prompted by any specific effort or takeover threat currently
perceived by management.

In addition to the increase in the authorized shares of common stock, in
connection with the merger, NPI has proposed to amend its restated certificate
of incorporation to provide for the change of the corporate name to "FalconStor
Software, Inc." Since the combined company will be adopting and pursuing
Falconstor's business strategy, changing NPI's name to FalconStor will allow
the name of the combined company to better reflect the business of the combined
company on a going-forward basis.

132

Vote Required and Board of Directors Recommendation

The affirmative vote of a majority of all outstanding shares of NPI common
stock is required for approval of this proposal. Abstentions and broker non-
votes will each have the same effect as a negative vote on this proposal.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE PROPOSAL TO
AMEND NPI'S RESTATED CERTIFICATE OF INCORPORATION TO INCREASE THE NUMBER OF
AUTHORIZED SHARES OF NPI'S COMMON STOCK FROM 60,000,000 SHARES TO 100,000,000
SHARES AND CHANGE THE CORPORATE NAME TO FALCONSTOR SOFTWARE, INC.

ADDITIONAL ANNUAL MEETING MATTERS FOR NPI

NPI PROPOSAL NO. 3

THE ELECTION OF DIRECTORS

The board of directors fixes, from time to time, the number of directors
authorized by the NPI's bylaws. There are currently five members of the board
of directors. NPI's bylaws provide that the directors shall be divided into
three classes, with the classes of directors serving for staggered, three-year
terms. If the merger is not completed, the two Class I Directors to be elected
at the annual meeting are to hold office until the annual meeting to be held in
2004 and until their successors have been elected and qualified. Unless
otherwise instructed, the proxy holders will vote the proxies received by them
for NPI's two nominees named below, who are presently directors of NPI. In the
event that any nominee of NPI is unable or declines to serve as a director at
the time of the annual meeting, the proxies will be voted for any nominee who
shall be designated by the present board of directors to fill the vacancy. In
the event that additional persons are nominated for election as directors, the
proxy holders intend to vote all proxies received by them in such a manner as
will assure the election of the nominee listed below, and, in such event, the
specific nominee to be voted for will be determined by the proxy holders.

The following information sets forth the names and ages of the nominees, and
each director of NPI whose term of office continues after the annual meeting

ELECTION OF THE NAMED NOMINEES.

135

NPI PROPOSAL NO. 4

RATIFICATION OF APPOINTMENT OF ACCOUNTANTS

In the event the merger is not completed, the NPI board of directors has
selected PricewaterhouseCoopers LLP as the independent accountants to audit the
financial statements of NPI for the fiscal year ending December 31, 2001.
PricewaterhouseCoopers has audited NPI's financial statements since 1989. A
representative of PricewaterhouseCoopers is expected to be present at the
annual meeting with the opportunity to make a statement if he or she so
desires, and is expected to be available to respond to appropriate questions.

The following table sets forth the aggregate fees billed to NPI for the
fiscal year ended December 31, 2000 by PricewaterhouseCoopers:

Audit Fees....................................................... $138,000
Financial Information Systems Design and Implementation
Fees............................................................ $ --
All Other Fees................................................... $170,000

The audit committee has considered the role of PricewaterhouseCoopers in
providing information technology, business consulting and tax services and
other non-audit services to NPI and has concluded that such services are
compatible with PricewaterhouseCoopers' independence as NPI's auditors.

Vote Required and Board of Directors Recommendation

The affirmative vote of a majority of the votes present or represented by
proxy and entitled to vote at the annual meeting of stockholders, at which a
quorum representing a majority of all outstanding shares of common stock of NPI
is present, either in person or by proxy, is required for approval of this
proposal. Abstentions and broker non-votes will each be counted as present for
purposes of determining the presence of a quorum. Abstentions will have the
same effect as a negative vote on this proposal. Broker non-votes will have no
effect on the outcome of this vote.

The board of directors has conditioned its appointment of NPI's independent
accountants upon the receipt of the affirmative vote. In the event that the
stockholders do not approve the selection of PricewaterhouseCoopers, the board
of directors will reconsider the appointment of the independent accountants.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE RATIFICATION
OF THE APPOINTMENT OF PRICEWATERHOUSECOOPERS LLP AS NPI'S INDEPENDENT
ACCOUNTANTS.

136

BOARD OF DIRECTORS MEETINGS AND COMMITTEES

The board of directors of NPI held a total of seven meetings and acted by
written consent on six separate occasions during 2000. No current director
participated in fewer than 75% of all such meetings and actions by the board of
directors, if any, and the committees, upon which such directors served, at the
time they were directors of NPI.

The board of directors currently has an audit committee and a compensation
committee. It does not have a nominating committee or a committee performing
the functions of a nominating committee. The functions of a nominating
committee are performed by the board of directors as a whole.

The audit committee recommends the engagement of NPI's independent
accountants, reviews and approves the scope of an annual audit and other
services performed by the independent accountants, and reviews and evaluates
NPI's accounting principles and its systems of internal accounting controls.
The audit committee held four meetings in 2000 and currently consists of Mr.
Gardner (chairperson), Mr. Brown and Mr. Hart. See "Report of the Audit
Committee."

The compensation committee reviews and approves the compensation policies
applicable to NPI's executive officers, and reviews and approves grants of
stock options pursuant to NPI's stock option plans. The compensation committee
held five meetings in 2000 and currently consists of Mr. Hart (chairperson),
Mr. Brown and Mr. Gardner. See "Report of the Compensation Committee of the
Board of Directors on Executive Compensation."

Option Grants in Last Fiscal Year

The following table sets forth details regarding stock options granted to
the Named Officers in 2000. NPI granted no stock appreciation rights in 2000.
In addition, in accordance with the SEC rules, the table shows the hypothetical
gains or "option spreads" that would exist for the respective options. These
gains are based on assumed rates of annual compound stock price appreciation of
5% and 10% from the date the options were granted over the full option term.
The actual value, if any, an executive may realize will depend on the spread
between the market price and the exercise price on the date the option is
exercised.

Employment Contracts, Termination of Employment and Change in Control
Arrangements

In September 2000, NPI entered into an employment agreement with James Regel
whereby Mr. Regel agreed to become the president and co-chief executive
officer. Pursuant to the employment agreement, Mr. Regel's annual base salary
is $250,000, and Mr. Regel is eligible to earn an annual bonus of $100,000, of
which $75,000 is guaranteed during the first 12 months of his employment and
the payment of the remaining balance is based on the attainment of performance
objectives determined by the compensation committee. Mr. Regel was granted an
option to purchase 375,000 shares of NPI's common stock with a vesting period
of four years. If a change in control occurs during the first six months of Mr.
Regel's employment, 50% of his unvested stock options will immediately vest; if
a change in control occurs between the seventh- and the twelfth-month of
employment, 75% of his unvested stock options will immediately vest; and if a
change in control occurs after 12 months, all of his unvested stock options
will immediately vest. If Mr. Regel is terminated without cause or resigns upon
constructive termination following a change of control, he is entitled to
receive the following: (i) an amount equal to his annual base salary at the
time of termination, (ii) medical insurance coverage for one year, and (iii)
immediate vesting of all unvested stock options which remain exercisable for
one year following the termination. In October 2000, the compensation committee
approved an increase in Mr. Regel's annual base salary to $350,000,
retroactively effective as of the commencement of his employment with NPI, and
any guaranteed bonus already paid was considered part of the increased salary.

In October 2000, NPI entered into an employment agreement with Ronald
Rutherford whereby Mr. Rutherford agreed to be the vice president of worldwide
sales. The employment agreement provides that Mr. Rutherford's annual base
salary is $155,000 and that his annual target commission is set at $100,000.
Upon the commencement of his employment with NPI, Mr. Rutherford was granted an
option to purchase 160,000 shares of NPI's common stock with a vesting period
of four years. If a change in control occurs during the first 12 months of
employment, 50% of Mr. Rutherford's stock options will immediately vest, and if
a change in control occurs after 12 months, all of Mr. Rutherford's stock
options will immediately vest. If Mr. Rutherford is terminated without cause,
he will receive a severance payment equal to his six-month base salary.

In December 2000, NPI entered into an employment agreement with James
Williams whereby Mr. Williams accepted the position of senior vice president of
finance and administration, secretary, treasurer and chief financial officer.
The employment agreement with Mr. Williams provides that his annual base salary
is $225,000. Upon the commencement of his employment with NPI, Mr. Williams was
granted an option to purchase 175,000 shares of NPI's common stock with a
vesting period of four years. If a change in control occurs during the first
six months of employment, 50% of Mr. Williams' stock options will immediately
vest; if a change in control occurs between the seventh- and the twelfth-month
of employment, 75% of Mr. Williams' stock options will immediately vest; and if
a change in control occurs after 12 months, all of Mr. Williams' stock options
will immediately vest. If Mr. Williams is terminated without cause, he will
receive a severance payment equal to his six-month base salary.

In December 2000, NPI also entered into an employment agreement with James
Baker whereby Mr. Baker agreed to be the senior vice president of engineering
and chief technology officer. The employment agreement with Mr. Baker provides
that his annual base salary is $235,000 and that he is eligible to earn a bonus
of $150,000 based on the performance objectives set forth in the bonus plan.
Upon the commencement of his employment with NPI, Mr. Baker was granted an
option to purchase 200,000 shares of NPI's common stock with a vesting period
of four years. If a change in control occurs during the first 12 months of
employment, 50% of Mr. Baker's stock options will immediately vest, and if a
change in control occurs after 12 months, all of Mr. Baker's stock options will
immediately vest. If Mr. Baker is terminated without cause, he will receive a
severance payment in the amount of his six-month base salary.

NPI has entered into a separation and release agreement with Joseph Botta.
Pursuant to the agreement, upon the closing of the proposed merger with
FalconStor, Mr. Botta shall receive a severance payment of $500,000 in total
(in the form of cash payment from NPI and proceeds from sales of NPI's common
stock upon

140

exercise of his vested stock options). In addition, in exchange for his signing
of the agreement, Mr. Botta waives his right to the severance benefits set
forth in the salary continuation agreement that was previously entered into
with NPI.

NPI has also entered into a salary continuation agreement with Robert Zecha.
Such agreement provides that in the event Mr. Zecha is terminated, including a
constructive termination or a termination within a specified time period around
a change in control, as those terms are defined in each agreement, he shall be
entitled to continued salary and bonus payments for a period of one year. Mr.
Zecha shall also be entitled to continued medical coverage by NPI during the
period of salary continuation unless he is covered by another employer's group
health plan. In the event of a change in control, all stock options granted to
Mr. Zecha shall become exercisable 30 days before the consummation of such
change in control.

NPI's 1997 Stock Plan provides that the board of directors may, in its sole
discretion, accelerate the vesting and the ability to exercise options in the
event of a change of control.

Compensation of Directors

Directors who are not employees of NPI are considered outside directors.
Outside directors are entitled to receive a director fee of $4,000 per fiscal
quarter so long as they remain directors of NPI. Directors do not receive any
additional or special remuneration for their services on any of the committees
established by the board of directors.

An outside director is eligible to participate in NPI's 1994 Outside
Directors Stock Option Plan. The Outside Directors Plan, as amended, provides
for the automatic granting of nonstatutory stock options to outside directors
of NPI. Each new outside director will be granted an option to purchase 15,000
shares of NPI's common stock on the date of election. Each continuing outside
director will be granted an option to purchase 5,000 shares of common stock on
the date of each annual meeting of stockholders.

Compensation Committee Interlocks and Insider Participation

During 2000, no member of the compensation committee was an executive
officer or employee of NPI. In addition, no executive officer of NPI has served
on the board of directors or compensation committee of any other entity that
has an executive officer serving as a member of NPI's board of directors.

Certain Relationships and Related Transactions

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires NPI's
executive officers, directors and persons who beneficially own more than 10% of
NPI's common stock to file initial reports of ownership and reports of changes
in ownership with the SEC. Such persons are required by SEC regulations to
furnish NPI with copies of all Section 16(a) forms filed by such persons.

Based solely on NPI's review of such forms furnished to NPI and written
representations from certain reporting persons, NPI believes that all filing
requirements applicable to NPI's executive officers, directors and more than
10% stockholders were complied with, except that Ronald Rutherford and James
Baker were late with respect to filing one form each.

141

Report of the Compensation Committee of the Board of Directors on Executive
Compensation

The compensation committee of the board of directors is comprised of non-
employee directors. The compensation committee is responsible for setting and
administering policies governing compensation of executive officers. The
compensation committee reviews the performance and compensation levels for
executive officers, sets salary and bonus levels and makes option grants under
NPI's 1997 Option Plan.

Compensation Policies

The goals of NPI's executive officer compensation policies are to attract,
retain and reward executive officers who contribute to NPI's success, to align
executive officer compensation with NPI's performance and to motivate executive
officers to achieve NPI's business objectives. NPI uses salary, bonuses and
stock options to achieve these goals. The compensation committee reviews
various available data, including compensation surveys, to enable the
compensation committee to compare NPI's compensation package with that of other
high technology companies of similar size and growth rates in NPI's geographic
area.

Compensation Components

Salaries are set for each executive officer with reference to a range of
salaries for comparable positions among high technology companies of similar
size, growth rate and location. Annual salary adjustments take into account
achievements of individual executive officers during the prior fiscal year as
measured against key company-wide objectives set each year by the board of
directors, as well as the executive officers' performance of their individual
responsibilities. Each compensation committee member weighs objective and
subjective performance factors, and a consensus is obtained through discussion.
The compensation committee also considers relative levels of responsibility
among executive officers in attempting to reach equitable and appropriate
projected compensation levels.

Cash incentive compensation is provided through participation in NPI's
executive bonus plan. The compensation committee determines the amount of an
individual's bonus based on subjective judgment of NPI's financial performance
and the achievement of established goals. A performance bonus of $200,000 was
paid to William Rosenberger in 2000.

The compensation committee strongly believes that equity ownership by
executive officers provides incentives to build stockholder value and aligns
the interests of executive officers with the stockholders. The size of an
initial option grant to an executive officer has generally been determined with
reference to comparable equity compensation offered by high technology
companies of similar size for similar positions, the responsibilities and
expected future contributions of the executive officer, as well as recruitment
considerations. In determining the size of subsequent grants, the compensation
committee has considered the individual executive officer's performance during
the previous fiscal year, the expected contributions during the coming year,
the amount of options already held and the level of recent grants. Stock
options granted to executive officers during 2000 were based upon available
data concerning option grants to executive officers of companies of similar
size, growth and location and a review of recent grants. The compensation
committee believes that future subsequent option grants, with vesting schedules
of up to four years, will provide strong incentives for executive officers to
remain with NPI.

Chief Executive Officer Compensation

The compensation of the chief executive officer is based upon the same
criteria outlined above for the other executive officers of NPI. While the
chief executive officer makes recommendations about the compensation levels,
goals and performance of the other executive officers, he does not participate
in the discussions regarding his compensation or performance.

142

Qualifying Compensation

The compensation committee has considered the potential impact of Section
162(m) of the Internal Revenue Code ("Section 162(m)") adopted under the
Federal Revenue Reconciliation Act of 1993. Section 162(m) disallows a tax
deduction for any publicly held corporation for certain executive officers'
compensation exceeding $1,000,000 per person in any taxable year unless it is
"performance based" within the meaning of Section 162(m). Since to date the
cash compensation plus restricted stock vesting of each of NPI's executive
officers has been below the $1,000,000 threshold and since the committee
believes that any options granted under NPI's option plan will meet the
requirement of being performance-based under the provisions of Section 162(m),
the committee believes that Section 162(m) will not reduce the tax deduction
available to NPI for fiscal year 2000 or prior years. NPI's policy is, to the
extent reasonable, to qualify its executive officers' compensation for
deductibility under the applicable tax laws.

Report of the Audit Committee

The audit committee of the board of directors consists of three independent
directors, each of whom has been determined to be "independent" under the
current listing standards of National Association of Securities Dealers. The
audit committee acts pursuant to the audit committee charter adopted by the
board of directors in July 2000, a copy of which is attached as Annex G to this
joint proxy statement/prospectus.

Management is responsible for NPI's internal controls and the financial
reporting process. The independent accountants are responsible for performing
an independent audit of the NPI's consolidated financial statements in
accordance with generally accepted auditing standards and expressing an opinion
on the conformity of those audited financial statements in accordance with
generally accepted accounting principles. The audit committee's responsibility
is to monitor and oversees these processes.

The audit committee has reviewed and discussed NPI's audited consolidated
financial statements for the year ended December 31, 2000 with management. The
audit committee has discussed with PricewaterhouseCoopers LLP, NPI's
independent accountants, the matters required to be discussed by Statement of
Auditing Standards No. 61 which includes, among other items, matters related to
the conduct of the audit of NPI's financial statements. The audit committee has
also received written disclosures and the letter from PricewaterhouseCoopers
LLP required by Independence Standards Board Standard No. 1, which relates to
the accountant's independence from NPI and its related entities, and has
discussed with PricewaterhouseCoopers LLP their independence from NPI.

Based on the review and discussions referred to above, the audit committee
recommended to NPI's board of directors that NPI's audited consolidated
financial statements be included in NPI's Annual Report on Form 10-K for the
fiscal year ended December 31, 2000.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers.

Section 145 of the Delaware General Corporation Law permits indemnification
of officers, directors, and other corporate agents under certain circumstances
and subject to certain limitations. NPI's certificate of incorporation and
bylaws provide that NPI shall indemnify NPI's directors, officers, employees,
and agents to the full extent permitted by Delaware law. These indemnification
provisions may be sufficiently broad to permit indemnification of NPI's
officers and directors for liabilities (including reimbursement of expenses
incurred) arising under the Securities Act of 1933, as amended.

NPI has a policy of directors' and officers' liability insurance that
insures NPI's directors and officers against the cost of defense, settlement or
payment of a judgment under certain circumstances.

At present, there is no pending litigation or proceeding involving any of
NPI's directors, officers, employees or other agents in which indemnification
is being sought. NPI are not aware of any threatened litigation that may result
in a claim for indemnification by any of NPI's directors, officers, employees
or other agents.

(2) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers, and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer, or controlling
person of the Registrant in the successful defense of any action, suit, or
proceeding) is asserted by such director, officer, or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

(3) The Registrant hereby undertakes to respond to requests for information
that is incorporated by reference into the joint proxy statement/prospectus
pursuant to Items 4, 10(b), 11 or 13 of this form, within one business day of
receipt of such request, and to send the incorporated documents by first class
mail or other equally prompt means. This includes information contained in
documents filed subsequent to the effective date of the Registration Statement
through the date of responding to the request.

(4) The Registrant hereby undertakes to supply by means of a post-effective
amendment all information concerning a transaction, and the company being
acquired involved therein, that was not the subject of and included in the
Registration Statement when it became effective.

II-2

(5)(A) The undersigned Registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of
a prospectus which as a part of this Registration Statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

(B) The Registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (A) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the Registration Statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

ARTICLE II

CONVERSION OF SECURITIES

Section 2.1 Conversion of Shares.

(a) By action of the holders of the outstanding shares of Series A Preferred
Stock, Series B Preferred Stock and Series C Preferred Stock (collectively,
"Company common stock"), each share of Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock outstanding immediately prior to
the Effective Time shall be converted immediately prior to the Effective Time
(subject to the satisfaction of the conditions set forth in Section 6.1 and
Section 6.3) into that number of shares of Company's common stock, par value
$0.001 (the "Company Common Stock") into which one share of Series A Common
Stock, Series B Preferred Stock and Series C Preferred Stock is then
convertible.

(b) At the Effective Time, each outstanding share of common stock, par value
$.001 per share, of Merger Sub shall, by virtue of the Merger and without any
action on the part of the Company, NPI or Merger Sub, be converted into one
fully paid and non-assessable share of common stock of the Surviving
Corporation.

(c) At the Effective Time, each share of Company Common Stock, issued and
outstanding immediately prior to the Effective Time (individually, a "Share"
and collectively, the "Shares") (other than (i) Shares held by the Company,
(ii) Shares held by NPI or Merger Sub or (iii) Dissenting Shares (as
hereinafter defined)) shall, by virtue of the Merger and without any action on
the part of NPI, Merger Sub or the Company or any holder thereof, be converted
into and be exchangeable for the right to receive the number (rounded to the
nearest ten thousandth) of fully paid and non-assessable shares of NPI Common
Stock equal to the Exchange Ratio.

(d) For purposes of this Agreement, the "Exchange Ratio" shall be determined
in accordance with the following formula:

E = 2(X + 0) + B-CB [2(X + 0)]
---------------------
Y + V

where E = the Exchange Ratio

X = all shares of NPI Common Stock issued and outstanding as of two
days prior to the NPI Stockholders Meeting

O = all shares of NPI Common Stock issuable under outstanding, vested,
in-the-money options to purchase such stock as of two days prior to
the NPI Stockholders Meeting

A-3

Merger by NPI prior to the Effective Time (the "Closing Cash");
provided that for purposes of this formula, Closing Cash shall not
exceed $90,000,000. For purposes of this paragraph, estimated cash
payments due under the Management Agreements shall be determined
(a) using the closing sales price of one share of NPI Common Stock
on Nasdaq two days prior to the NPI Stockholders' Meeting and (b)
by giving effect to any acceleration of vesting of options caused
by the Closing

B = $90,000,000

Y = all outstanding shares of Company Common Stock (assuming conversion
of all outstanding shares of Company Preferred Stock into shares of
Company Common Stock) minus shares of Company Preferred Stock or
Company Common Stock owned by NPI or the Company, calculated two
days prior to the NPI Stockholders' Meeting

V = all shares of Company Common Stock issuable under outstanding,
vested, in-the-money options or warrants to purchase such stock or
other securities convertible or exchangeable for shares of Company
Common Stock, calculated two days prior to the NPI Stockholders'
Meeting

All such shares of NPI Common Stock issued pursuant to this Section 2.1,
together with any cash paid in lieu of fractional shares of NPI Common Stock
to be paid pursuant to Section 2.7, are referred to herein as the "Merger
Consideration."

(e) At the Effective Time, each Share of Company Common Stock owned by NPI,
Merger Sub or the Company immediately prior to the Effective Time shall be
canceled and extinguished without any conversion thereof and no consideration
shall be delivered in exchange therefor.

(f) If, between the date of this Agreement and the Effective Time, either
(i) the outstanding shares of Company Common Stock, Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock shall have been changed
into a different number of shares or a different class by reason of any stock
dividend, subdivision, reclassification, recapitalization, split, combination
or exchange of shares, or any similar event, or (ii) the number of shares of
Company Common Stock issuable upon conversion of each share of Series A
Preferred Stock, Series B Preferred Stock or Series C Preferred Stock shall
have been changed pursuant to contract, an anti-dilution adjustment provision
contained in the Company's certificate of incorporation or otherwise, the
calculation of the Exchange Ratio shall be correspondingly adjusted to the
extent necessary to reflect such stock dividend, subdivision,
reclassification, recapitalization, split, combination or exchange of shares,
change in conversion ratio or such similar event.

(g) If, between the date of this Agreement and the Effective Time, the
outstanding shares of NPI Common Stock shall have been changed into a
different number of shares or a different class by reason of any stock
dividend, subdivision, reclassification, recapitalization, split, combination
or exchange of shares, or any similar event, the calculation of the Exchange
Ratio shall be correspondingly adjusted to the extent necessary to reflect
such stock dividend, subdivision, reclassification, recapitalization, split,
combination or exchange of shares, or such similar event.

Section 2.2 Stock Options. At the Effective Time, the Company Stock
Options, whether vested or unvested, will be assumed by NPI ("Assumed Stock
Options"). Section 2.2 of the Company Disclosure Schedule hereto sets forth a
true and complete list as of the date hereof of all holders of outstanding
options to purchase shares of Company Common Stock ("Company Stock Options"),
including the number of shares of Company Common Stock subject to each such
option, the exercise or vesting schedule, the exercise price per share and the
term of each such option. On the Closing Date, the Company shall deliver to
NPI an updated Section 2.2 of the Company Disclosure Schedule hereto current
as of such date. Each such option so assumed by NPI under this Agreement shall
continue to have, and be subject to, the same terms and conditions set forth
in the Company Stock Option Plan ("Company Option Plan") and any other
document governing such option

A-4

immediately prior to the Effective Time, except that (a) such option will be
exercisable for that number of whole shares of NPI Common Stock equal to the
product of the number of shares of Company Common Stock that were issuable upon
exercise of such option immediately prior to the Effective Time multiplied by
the Exchange Ratio and rounded down to the nearest whole number of shares of
NPI Common Stock, (b) the per share exercise price for the shares of NPI Common
Stock issuable upon exercise of such assumed option will be equal to the
quotient determined by dividing the exercise price per share of Company Common
Stock at which such option was exercisable immediately prior to the Effective
Time by the Exchange Ratio, rounded up to the nearest whole tenth of a cent and
(c) any restriction on the exercisability of such Company Stock Option shall
continue in full force and effect, and the term, exercisability, vesting
schedule and other provisions of such Company Stock Option shall remain
unchanged. Consistent with the terms of the Company Option Plan and the
documents governing the outstanding options, the Merger will not terminate any
of the outstanding options under the Company Option Plan or accelerate the
exercisability or vesting of such options or the shares of NPI Common Stock
which will be subject to those options upon NPI's assumption of the options in
the Merger. It is the intention of the parties that the options so assumed by
NPI following the Effective Time will remain incentive stock options as defined
in Section 422 of the Code to the extent such options qualified as incentive
stock options prior to the Effective Time, and the parties hereto shall use
their commercially reasonable efforts to carry out such intention. Within 10
business days after the Effective Time, NPI will issue to each person who,
immediately prior to the Effective Time was a holder of an outstanding option
under the Company Option Plan a document in form and substance reasonably
satisfactory to the Company evidencing the foregoing assumption of such option
by NPI. NPI agrees to file with the Securities and Exchange Commission ("SEC")
after the Closing a registration statement on Form S-8 covering the shares of
NPI Common Stock issuable pursuant to Assumed Stock Options. The Company shall
cooperate with and assist NPI in the preparation of such registration
statement.

Section 2.3 Exchange Fund. Prior to the Effective Time, NPI shall appoint a
commercial bank or trust company reasonably acceptable to the Company to act as
exchange agent hereunder for the purpose of exchanging Shares for the Merger
Consideration (the "Exchange Agent"). At or prior to the Effective Time, NPI
shall deposit with the Exchange Agent, in trust for the benefit of holders of
Shares, certificates representing the NPI Common Stock issuable pursuant to
Section 2.1 in exchange for outstanding Shares and an estimated amount of cash
sufficient to pay the cash payable in lieu of fractional shares pursuant to
Section 2.7. NPI agrees to make available to the Exchange Agent from time to
time as needed, cash sufficient to pay cash in lieu of fractional shares
pursuant to Section 2.7 and any dividends and other distributions pursuant to
Section 2.5. Any cash and certificates of NPI Common Stock deposited with the
Exchange Agent shall hereinafter be referred to as the "Exchange Fund."

Section 2.4 Exchange Procedures. As soon as reasonably practicable after the
Effective Time (and in any event within three business days after the Effective
Time), NPI and the Surviving Corporation shall use their commercially
reasonable efforts to cause the Exchange Agent to mail to each holder of a
certificate or certificates which immediately prior to the Effective Time
represented outstanding Shares (the "Certificates") (a) a letter of transmittal
which shall specify that delivery shall be effective, and risk of loss and
title to the Certificates shall pass, only upon delivery of the Certificates to
the Exchange Agent, and which letter shall be in customary form and have such
other provisions as NPI may reasonably specify; and (b) instructions for
effecting the surrender of such Certificates in exchange for the Merger
Consideration. Upon surrender of a Certificate to the Exchange Agent together
with such letter of transmittal, duly executed and completed in accordance with
the instructions thereto, and such other documents as may reasonably be
required by the Exchange Agent, the holder of such Certificate shall be
entitled to receive in exchange therefor (i) shares of NPI Common Stock
representing, in the aggregate, the whole number of shares that such holder has
the right to receive pursuant to Section 2.1 (after taking into account all
Shares then held by such holder) and (ii) a check in the amount equal to the
cash that such holder has the right to receive pursuant to the provisions of
this ARTICLE II, including cash in lieu of any dividends and other
distributions pursuant to Section 2.5 and cash in lieu of fractional shares
pursuant to Section 2.7, and the Shares formerly represented by such
Certificate and the Certificate so surrendered shall forthwith be canceled.
Until surrendered as contemplated by this Article II, each

A-5

Certificate shall be deemed at any time after the Effective Date to represent
only the right to receive the Merger Consideration payable upon surrender of
the Certificates. No interest will be paid or will accrue on any cash payable
pursuant to Section 2.5 or Section 2.7. In the event of a transfer of ownership
of Shares which is not registered in the transfer records of the Company,
shares of NPI Common Stock evidencing, in the aggregate, the proper number of
shares of NPI Common Stock, a check in the proper amount of cash in lieu of any
fractional shares of NPI Common Stock pursuant to Section 2.7 and any dividends
or other distributions to which such holder is entitled pursuant to Section
2.5, may be issued with respect to such Shares to such a transferee if the
Certificate representing such Shares is presented to the Exchange Agent,
accompanied by all documents required to evidence and effect such transfer and
to evidence that any applicable Transfer Taxes have been paid.

Section 2.5 Distributions with Respect to Unsurrendered Certificates. No
dividends or other distributions declared or made with respect to shares of NPI
Common Stock with a record date after the Effective Time shall be paid to the
holder of any unsurrendered Certificate with respect to the shares of NPI
Common Stock that such holder would be entitled to receive upon surrender of
such Certificate and no cash payment in lieu of fractional shares of NPI Common
Stock shall be paid to any such holder pursuant to Section 2.7 until such
holder shall surrender such Certificate in accordance with Section 2.4. Subject
to the effect of applicable Laws (as hereinafter defined), following surrender
of any such Certificate, there shall be paid to such holder of shares of NPI
Common Stock issuable in exchange therefor, without interest, (a) promptly
after the time of such surrender, the amount of any cash payable in lieu of
fractional shares of NPI Common Stock to which such holder is entitled pursuant
to Section 2.7 and the amount of dividends or other distributions with a record
date after the Effective Time theretofore paid with respect to such whole
shares of NPI Common Stock, and (b) at the appropriate payment date, the amount
of dividends or other distributions with a record date after the Effective Time
but prior to such surrender and a payment date subsequent to such surrender
payable with respect to such shares of NPI Common Stock.

Section 2.6 No Further Ownership Rights in Company Common Stock. All shares
of NPI Common Stock issued and cash paid upon conversion of the Shares in
accordance with the terms of ARTICLE I and this ARTICLE II (including any cash
paid pursuant to Section 2.5 and Section 2.7) shall be deemed to have been
issued or paid in full satisfaction of all rights pertaining to the Shares.

Section 2.7 No Fractional Shares of NPI Common Stock.

(a) No certificates or scrip of shares of NPI Common Stock representing
fractional shares of NPI Common Stock or book-entry credit of the same shall be
issued upon the surrender for exchange of Certificates and such fractional
share interests will not entitle the owner thereof to vote or to have any
rights of a stockholder of NPI or a holder of shares of NPI Common Stock.

(b) Notwithstanding any other provision of this Agreement, each holder of
Shares exchanged pursuant to the Merger who would otherwise have been entitled
to receive a fraction of a share of NPI Common Stock (after taking into account
all Certificates delivered by such holder) shall receive, in lieu thereof, cash
(without interest) in an amount equal to the product of (i) such fractional
part of a share of NPI Common Stock multiplied by (ii) the reported closing
sales price of one share of NPI Common Stock on the Nasdaq National Market
("Nasdaq") at the Effective Time. As promptly as practicable after the
determination of the aggregate amount of cash to be paid to holders of
fractional interests, the Exchange Agent shall notify NPI and NPI shall deposit
such amount with the Exchange Agent (to the extent the amount deposited with
the Exchange Agent pursuant to Section 2.3 is insufficient), and shall cause
the Exchange Agent to forward payments to such holders of fractional interests
subject to and in accordance with the terms hereof.

Section 2.8 Termination of Exchange Fund. Any portion of the Exchange Fund
which remains undistributed to the holders of Certificates for six months after
the Effective Time shall be delivered to the Surviving Corporation or otherwise
on the instruction of the Surviving Corporation, and any holders of the
Certificates who have not theretofore complied with this ARTICLE II shall
thereafter look only to the

A-6

Surviving Corporation and NPI for the Merger Consideration with respect to the
Shares formerly represented thereby to which such holders are entitled pursuant
to Section 2.1 and Section 2.4, any cash in lieu of fractional shares of NPI
Common Stock to which such holders are entitled pursuant to Section 2.7 and any
dividends or distributions with respect to shares of NPI Common Stock to which
such holders are entitled pursuant to Section 2.5. Any such portion of the
Exchange Fund remaining unclaimed by holders of Shares five years after the
Effective Time (or such earlier date immediately prior to such time as such
amounts would otherwise escheat to or become property of any Governmental
Entity) shall, to the extent permitted by law, become the property of the
Surviving Corporation free and clear of any claims or interest of any person
previously entitled thereto.

Section 2.9 No Liability. None of NPI, Merger Sub, the Company, the
Surviving Corporation or the Exchange Agent shall be liable to any person in
respect of any Merger Consideration from the Exchange Fund delivered to a
public official pursuant to any applicable abandoned property, escheat or
similar Law.

Section 2.10 Investment of the Exchange Fund. The Exchange Agent shall
invest any cash included in the Exchange Fund as directed by NPI on a daily
basis. Any interest and other income resulting from such investments promptly
shall be paid to NPI.

Section 2.11 Lost Certificates. If any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
the Surviving Corporation, the posting by such person of a bond in such
reasonable amount as the Surviving Corporation may direct as indemnity by such
person against any claim that may be made against the Surviving Corporation
with respect to such Certificate, the Exchange Agent will deliver in exchange
for such lost, stolen or destroyed Certificate the applicable Merger
Consideration with respect to the Shares formerly represented thereby and any
unpaid dividends and distributions on shares of NPI Common Stock deliverable in
respect thereof, pursuant to this Agreement.

Section 2.12 Backup Withholding Rights. Each of NPI, the Surviving
Corporation and the Exchange Agent shall be entitled to deduct and withhold
from the Merger Consideration otherwise payable pursuant to this Agreement to
any holder of Shares such amounts as it is required to deduct and withhold with
respect to the making of such payment under the Code and the rules and
regulations promulgated thereunder, or any provision of a tax Law. To the
extent that amounts are so withheld by NPI, the Surviving Corporation or the
Exchange Agent, as the case may be, such withheld amounts shall be treated for
all purposes of this Agreement as having been paid to the holder of the Shares
in respect to which such deduction and withholding was made by NPI, the
Surviving Corporation or the Exchange Agent, as the case may be.

Section 2.13 Tax Consequences. It is intended by the parties hereto that the
Merger shall constitute a reorganization within the meaning of Section 368(a)
of the Code. Each party hereto shall use its commercially reasonable efforts to
cause the Merger to be so qualified, shall report the transactions contemplated
by this Agreement in a manner consistent with such reorganization treatment and
will not take any position inconsistent therewith in any Tax Return (as
hereinafter defined), refund claim, litigation or otherwise unless required to
do so by law. The Merger shall be treated as a purchase for accounting
purposes.

Section 2.14 Stock Transfer Books. The stock transfer books of the Company
shall be closed immediately upon the Effective Time and there shall be no
further registration of transfers of Shares thereafter on the records of the
Company. On or after the Effective Time, any Certificates presented to the
Exchange Agent or NPI for any reason shall be converted into the Merger
Consideration with respect to the Shares formerly represented thereby, any cash
in lieu of fractional shares of NPI Common Stock to which the holders thereof
are entitled pursuant to Section 2.7 and any dividends or other distributions
to which the holders thereof are entitled pursuant to Section 2.5.

Section 2.15 Affiliates. Notwithstanding anything to the contrary herein, no
shares of NPI Common Stock or cash shall be delivered to a person who may be
deemed an "affiliate" of the Company for purposes

A-7

of Rule 145 under the Securities Act of 1933, as amended (the "Securities
Act"), until such person has executed and delivered to NPI the written
agreement contemplated by Section 5.10.

Section 2.16 Appraisal Rights. Notwithstanding anything in this Agreement to
the contrary, Shares that are issued and outstanding immediately prior to the
Effective Time and which are held by stockholders who did not vote in favor of
the Merger (the "Dissenting Shares"), which stockholders comply with all of the
relevant provisions of Delaware Law (the "Dissenting Stockholders"), shall not
be converted into or be exchangeable for the right to receive the Merger
Consideration, unless and until such holders shall have failed to perfect or
shall have effectively withdrawn or lost their rights to appraisal under
Delaware Law. If any Dissenting Shareholder shall have failed to perfect or
shall have effectively withdrawn or lost such right, such holder's Shares shall
thereupon be converted into and become exchangeable for the right to receive,
as of the Effective Time, the Merger Consideration without any interest
thereon. The Company shall give NPI (a) prompt notice of any written demands
for appraisal of any Shares, attempted withdrawals of such demands and any
other instruments served pursuant to Delaware Law and received by the Company
relating to stockholders' rights of appraisal, and (b) the opportunity to
direct, in its reasonable business judgment, all negotiations and proceedings
with respect to demands for appraisal under Delaware Law. Neither the Company
nor the Surviving Corporation shall, except with the prior written consent of
NPI, voluntarily make any payment with respect to, or settle or offer to
settle, any such demand for payment. If any Dissenting Shareholder shall fail
to perfect or shall have effectively withdrawn or lost the right to dissent,
the Shares held by such Dissenting Shareholder shall thereupon be treated as
though such Shares had been converted into the right to receive the Merger
Consideration pursuant to Section 2.1.

and in good standing under the laws of the jurisdiction of its incorporation
and has the corporate power and authority required for it to own its properties
and assets and to carry on its business as it is now being conducted. The
Representing Party is duly qualified to do business and is in good standing in
each jurisdiction in which the ownership of its properties or the conduct of
its business requires such qualification, except for jurisdictions in which the
failure to be so qualified or in good standing would not, individually or in
the aggregate, be reasonably likely to have a Material Adverse Effect on the
Representing Party or substantially delay consummation of the transactions
contemplated by this Agreement or otherwise prevent the Representing Party from
performing its obligations hereunder. As used in this Agreement, "Material
Adverse Effect" means any change, effect, event, occurrence, state of facts or

Effect on a Representing Party as indicated (A) any change in the market price
or trading volume of NPI Common Stock after the date hereof; (B) any failure by
the Representing Party to meet internal revenue or earnings projections or
forecasts or published revenue or earnings projections for any period ending

substantially consistent with the NPI's internal projections; (D) any adverse

adverse change, effect, event, occurrence, state of facts or developments
directly caused by, resulting from or attributable to conditions affecting the
data storage or networking industries as a whole or the U.S. or world economies
as a whole; (G) any adverse change, effect, event, occurrence, state of facts
or development directly resulting from or attributable or relating to out-of-

other fees and expenses) incurred in connection with the transactions
contemplated by this Agreement; or (H) any adverse change, effect, event,
occurrence, state of facts or development directly caused by compliance with
the terms of, or the taking of any action required by, this Agreement; and
provided, further, that with respect to any dispute regarding whether any
adverse change, effect, event, occurrence, state of facts or development is
"directly caused" by any of the foregoing, the Representing Party shall have

jurisdiction in which the ownership of its properties or the conduct of its
business requires such qualification, except for jurisdictions in which the
failure to be so qualified or in good standing would not, individually or in

Representing Party, taken as a whole. All the outstanding shares of capital
stock of, or other ownership interests in, the Representing Party's
Subsidiaries are duly authorized, validly issued, fully paid and non-assessable
and, with respect to such shares or ownership interests that are owned by the

financial, regulatory and other aspects of the proposal and identity of the
offeror) as compared to the transactions contemplated hereby and which is
reasonably capable of being consummated; provided, however, that any such
offer shall not be deemed to be a Company Superior Proposal if any
financing required to consummate the transaction contemplated by such offer
is not committed and is not reasonably capable of being obtained by such
third party.

(ii) The Company board of directors will not withdraw or modify, or
propose to withdraw or modify, in a manner adverse to NPI, its approval or

inform the Company of the receipt by NPI of any subsequent NPI Acquisition
Proposal. NPI and its Subsidiaries shall take all necessary steps to
promptly inform the individuals or entities referred to in the first
sentence of this Section 5.5(b) of the obligations undertaken in this
Section 5.5(b). "NPI Acquisition Proposal" means an inquiry, offer or
proposal regarding any of the following (other than the transactions
contemplated by this Agreement) involving NPI: (v) any merger,
consolidation, share exchange, recapitalization, business combination or
other similar transaction; (w) any sale of shares of capital stock of NPI
after which stockholders of NPI immediately prior to such sale would hold
less than a majority of the outstanding capital stock of NPI, (x) any sale,
lease, exchange, mortgage, pledge, transfer or other disposition of all or
substantially all the assets of NPI in a single transaction or series of
related transactions, other than assets of NPI related directly to NPI's
Ethernet switching business, (y) any tender offer or exchange offer for 20%
or more of the outstanding NPI Common Stock or the filing of a registration
statement under the Securities Act in connection therewith, or (z) any
public announcement of a proposal, plan or intention to do any of the
foregoing or any agreement to engage in any of the foregoing. "NPI Superior
Proposal" shall mean an unsolicited, bona fide written offer made by a
third party to purchase all of outstanding NPI Common Stock on terms that
the board of directors of NPI determines, in its reasonable judgment, to be
more favorable to the NPI and its stockholders (taking into account, among
other things, all legal, financial, regulatory and other aspects of the
proposal and identity of the offeror) as compared to the transactions
contemplated hereby and which reasonably capable of being consummated;
provided, however, that any such offer shall not be deemed to be a NPI
Superior Proposal if any financing required to consummate the transaction
contemplated by such offer is not committed and is not reasonably capable
of being obtained by such third party.

A-32

(ii) The NPI board of directors will not withdraw or modify, or propose
to withdraw or modify, in a manner adverse to the Company, its approval or
recommendation of this Agreement or the Merger unless the NPI board of
directors, after consultation with independent legal counsel, determines in
good faith that such action is necessary to avoid a breach by the NPI board
of directors of its fiduciary duties to the NPI stockholders under
applicable Law. Nothing contained in this Section 5.5(b) shall prohibit NPI
from making any disclosure to the NPI stockholders which, in the good faith
reasonable judgment of the NPI board of directors, after consultation with
independent legal counsel, is required under applicable Law; provided, that
except as otherwise permitted in this Section 5.5(b), NPI may not withdraw
or modify, or propose to withdraw or modify, its position with respect to
the Merger or approve or recommend, or propose to approve or recommend, an
NPI Acquisition Proposal. Nothing in this Section 5.5(b) shall (A) permit
NPI to terminate this Agreement or (B) affect any other obligations of NPI
under this Agreement.

Section 5.6 Public Announcements. Each of NPI, Merger Sub and the Company
will consult with one another before issuing any press release or otherwise
making any public statements in respect of the transactions contemplated by
this Agreement, including, the Merger, and shall not issue any such press
release or make any such public statement prior to such consultation, except as
may be required by applicable Law or by obligations pursuant to any listing
agreement with Nasdaq, as determined by NPI, Merger Sub or the Company, as the
case may be, a copy of which shall be sent simultaneously to the other party
upon such release.

Section 5.7 Indemnification.

(a) The Company shall, and from and after the Effective Time, the Surviving
Corporation and NPI shall, indemnify, defend and hold harmless the present and
former directors and officers of the Company (the "Indemnified Parties")
against all losses, claims, damages, costs, expenses (including reasonable
attorneys' fees and expenses), liabilities or judgments or amounts that are
paid in settlement with the approval of the indemnifying party of or in
connection with any threatened or actual claim, action, suit, proceeding or
investigation based in whole or in part on or arising in whole or in part out
of or pertaining to the fact that such person is or was a director or officer
of the Company whether pertaining to any matter existing at or prior to the
Effective Time and whether asserted or claimed prior to, at or after the
Effective Time ("Indemnified Liabilities"), including all Indemnified
Liabilities based in whole or in part on, or arising in whole or in part out
of, or pertaining to this Agreement or the transactions contemplated hereby, in
each case to the fullest extent the Company is permitted under the Company's
certificate of incorporation and/or bylaws in effect immediately prior to the
Merger and under Delaware Law as the same exists or may hereafter be amended
(but, in the case of any amendment, only to the extent that such amendment
permits broader rights than such law permitted prior to such amendment and only
to the extent such amendment is not retroactively applicable) to indemnify its
own directors or officers, as the case may be. Without limiting the foregoing,
in the event any such claim, action, suit, proceeding or investigation is
brought against any Indemnified Parties (whether arising before or after the
Effective Time), (a) the Indemnified Parties may retain counsel satisfactory to
them and the Company or, from and after the Effective Time, the Surviving
Corporation, and the Surviving Corporation or NPI, as applicable, shall pay all
reasonable fees and expenses of such counsel for the Indemnified Parties
promptly as statements therefor are received and otherwise advance to such
Indemnified Party upon request reimbursement of reasonable documented expenses
incurred, in either case to the fullest extent and in the manner permitted by
Delaware Law; and (b) the Company or the Surviving Corporation, as applicable,
will use all reasonable efforts to assist in the vigorous defense of any such
matter, provided that neither the Company, NPI nor the Surviving Corporation
shall be liable for any settlement effected without its prior written consent
(which consent shall not be unreasonably withheld). Any Indemnified Party
wishing to claim indemnification under this Section 5.7, upon learning of any
such claim, action, suit, proceeding or investigation, shall promptly notify
the Company (or after the Effective Time, the Surviving Corporation) (but the
failure so to notify shall not relieve a party from any liability which it may
have under this Section 5.7 except to the extent such failure materially
prejudices such party), and shall to the extent required by the Company's
certificate of incorporation and/or bylaws in effect immediately prior to the
Merger and Delaware Law deliver to the Company (or after the Effective Time,
the Surviving Corporation) the undertaking contemplated by the Company's
certificate of

A-33

incorporation and/or bylaws in effect immediately prior to the Merger and
Delaware Law. The Indemnified Parties as a group may retain only one law firm
to represent them with respect to each such matter unless there is, under
applicable standards of professional conduct, a conflict on any significant
issue between the positions of any two or more Indemnified Parties.

(b) NPI, Merger Sub and the Company agree that all rights to indemnification
and all limitations of liability existing in favor of the Indemnified Party as
provided in the Company's certificate of incorporation and bylaws as in effect
as of the date hereof shall survive the Merger and shall continue in full force
and effect, without any amendment thereto, for a period of six years from the
Effective Time to the extent such rights are consistent with Delaware Law;
provided, that in the event any claim or claims are asserted or made within
such six-year period all rights to indemnification in respect of any such claim
or claims shall continue until disposition of any and all such claims; provided
further, that any determination required to be made with respect to whether an
Indemnified Party's conduct complies with the standards set forth under
Delaware Law, the Company's certificate of incorporation or bylaws or such
agreements, as the case may be, shall be made by independent legal counsel
selected by the Indemnified Party and reasonably acceptable to NPI; and
provided further, that nothing in this Section 5.7 shall impair any rights or
obligations of any present or former directors or officers of the Company.

(c) In the event NPI or the Surviving Corporation or any of their successors
or assigns (i) consolidates with or mergers into any other person and shall not
be the continuing or surviving corporation or entity of such consolidation or
merger, or (ii) transfers or conveys all or substantially all of its properties
and assets to any person, then, and in each such case, to the extent necessary
to effectuate the purposes of this Section 5.7, proper provision shall be made
so that the successors and assigns of NPI and the Surviving Corporation assume
the obligations set forth in this Section 5.7 and none of the actions described
in clauses (i) or (ii) shall be taken until such provision is made.

(d) NPI or the Surviving Corporation shall maintain directors' and officers'
liability insurance ("D&O Insurance") for a period of not less than six years
after the Effective Date; provided, that (i) the Surviving Corporation may
substitute therefor policies of substantially similar coverage and amounts
containing terms no less advantageous to such former directors or officers and
(ii) if the existing D&O Insurance expires or is canceled during such period,
NPI or the Surviving Corporation will use its commercially reasonable efforts
to obtain substantially similar D&O Insurance, (iii) in no event shall NPI or
the Surviving Corporation be required to expend an amount per year in excess of
150% of current annual premiums paid by NPI to maintain or procure D&O
insurance pursuant hereto; and (iv) if the annual premiums of such D&O
Insurance would exceed 150% of current annual premiums, NPI or the Surviving
Corporation shall obtain a policy with the greatest coverage available for a
cost not exceeding 150% of current annual premiums.

Section 5.8 Notification of Certain Matters. The Company shall give prompt
notice to NPI and Merger Sub, and NPI and Merger Sub shall give prompt notice
to the Company, of (a) the occurrence or nonoccurrence of any event the
occurrence or nonoccurrence of which would be likely to cause any
representation or warranty contained in this Agreement to be untrue or
inaccurate in any material respect at or prior to the Effective Time, (b) any
material failure of the Company, NPI or Merger Sub, as the case may be, to
comply with or satisfy any covenant, condition or agreement to be complied with
or satisfied by it hereunder, (c) any notice or other communication from any
third party alleging that the consent of such third party is or may be required
in connection with the transactions contemplated by this Agreement, or (d) any
facts or circumstances that could reasonably be expected to result in a
Material Adverse Effect; provided, however, that the delivery of any notice
pursuant to this Section 5.8 shall not cure such breach or non-compliance or
limit or otherwise affect the rights, obligations or remedies available
hereunder to the party receiving such notice.

Section 5.9 Employee Matters, Management Agreements.

(a) NPI will cause the Surviving Corporation to honor the obligations of the
Company under the provisions of all Benefit Plans and Employee Arrangements set
forth in the Company's Disclosure Schedule,

A-34

subject to NPI's right to amend or terminate any such Benefit Plan or Employee
Arrangement in accordance with its terms. After the Effective Time, the
employees of the Company will be eligible to participate in the Company's
Benefit Plans or, if so determined by NPI, NPI's applicable Benefit Plans, as
such plans may be in effect from time to time, and, at NPI's sole discretion,
will become employees of NPI. With respect to each such employee of the
Company, service with the Company may be counted for purposes of determining
periods of eligibility to participate or to vest in benefits under any
applicable Benefit Plan of NPI. At NPI's sole discretion, administrative
functions, including but not limited to payroll processing, may be transferred
to processors of NPI's choosing.

(b) The Company, NPI and Merger Sub agree that the Merger shall constitute a
change in control with respect to the Management Agreements and any payments or
benefits due to parties under the Management Agreements resulting therefrom
shall be paid promptly to each payee after the expiration of such payee's NPI
Lockup Agreement.

(c) At the Closing, NPI may cause the Surviving Corporation to deposit with
an escrow agent reasonably acceptable to all parties hereto and pursuant to the
terms of a mutually acceptable escrow agreement, an amount sufficient to pay
any amount due pursuant to retention agreements disclosed in the NPI Disclosure
Schedule.

Section 5.10 Affiliate Agreements. Section 5.10 of the Company Disclosure
Schedule sets forth a list of all persons who are, and all persons who to the
Company's knowledge will be at the Closing Date, "affiliates" of the Company
for purposes of Rule 145 under the Securities Act. The Company will cause such
list to be updated promptly through the Closing Date. No later than 15 days
after the date of this Agreement (but in any event prior to the Effective
Time), the Company shall cause its "affiliates" to deliver to NPI an Affiliate
Agreement.

Section 5.11 Lock-up Agreements.

(a) Section 5.11 of the Company Disclosure Schedule sets forth a list of all

NPI's officers, directors, stockholders affiliated with NPI's officers and

entities to deliver to NPI an NPI Lock-up Agreement.

Section 5.12 Listing of Stock. NPI shall use its commercially reasonable
efforts to cause the shares of NPI Common Stock to be issued in connection with
the Merger to be approved for listing on Nasdaq on or prior to the Closing

Section 5.13 Antitakeover Statutes. If any antitakeover statute is or may
become applicable to the Merger, each of NPI and the Company shall take such
actions as are necessary so that the transactions contemplated by this
Agreement may be consummated as promptly as practicable on the terms
contemplated hereby and otherwise act to eliminate or minimize the effects of
any antitakeover statute on the Merger.

Section 5.14 Third Party Consents.

(a) Each of NPI, Merger Sub and the Company shall use its commercially
reasonable efforts to obtain at the earliest practicable date all consents of
third parties (including, but not limited to, such as are listed on Section 3.3
of the Company Disclosure Schedule or NPI Disclosure Schedule, as applicable)
and Governmental Entities necessary to the consummation of the transactions
contemplated hereby (the "Third Party Consents") and will provide to the other
parties hereto copies of each such Third Party Consent promptly after it is
obtained. Each of NPI, Merger Sub and the Company agrees to cooperate fully
with the other parties hereto in

A-35

connection with the obtaining of the Third Party Consents; provided, however,
that no party shall be required to pay any additional sums to secure such Third
Party Consents of the other parties hereto.

(b) The Company and NPI shall take all reasonable actions necessary to file
as soon as practicable notifications under the HSR Act and to respond as
promptly as practicable to any inquiries received from the Federal Trade
Commission and the Antitrust Division of the Department of Justice for
additional information or documentation and to respond as soon as practicable
to all inquiries and requests received from any Governmental Entity in
connection with antitrust matters. Notwithstanding anything to the contrary

Subsidiaries shall not be required to divest, or agree to any restrictions with
respect to, any of its businesses or assets or the businesses or assets to be
acquired in connection with the transactions contemplated hereby. Nothing
herein shall prevent NPI, on not more than one occasion, from withdrawing a

thereafter in accordance with the terms hereof.

(c) In furtherance and not in limitation of the covenants of the parties
contained in Section 5.14(a) and Section 5.14(b), if any administrative or
judicial action or proceeding, including any proceeding by a private party, is
instituted (or threatened to be instituted) challenging any transaction
contemplated by this Agreement, each of NPI, Merger Sub and the Company shall
cooperate in all respects with each other and use its respective commercially
reasonable efforts to contest and resist any such action or proceeding and to

challenge as such Governmental Entity or private party may have to such
transactions under such regulatory Law so as to permit consummation of the
transactions contemplated by this Agreement.

ANNEX B

LEHMAN BROTHERS

March 30, 2001

Board of Directors
Network Peripherals Inc.
2859 Bayview Drive
Fremont, California 94538

Members of the Board:

We understand that Network Peripherals Inc. ("NPI" or the "Company") intends
to enter into an option agreement (the "Option Agreement") with FalconStor,
Inc. ("FalconStor") under which NPI will have an exclusive option (the
"Option") to merge with FalconStor and that NPI intends to exercise the Option
and merge FalconStor with a wholly owned subsidiary of NPI (the "Proposed
Transaction"). In the Proposed Transaction, all of the issued and outstanding
shares of capital stock of FalconStor and all outstanding, unexpired and
unexercised options, warrants, convertible notes, and other rights to acquire
or receive shares of FalconStor capital stock (collectively, the "FalconStor
Equity") will be converted into the right to receive, in the aggregate, between
68.9% and 71.5% of the shares of common stock of NPI on a fully-diluted basis
(the "Aggregate Consideration"). We further understand that the exact
percentage of shares to be paid by the Company will vary depending on (1) the
amount of cash, cash equivalents, short term investments and certain other
assets held by the Company at the time of the Proposed Transaction, (2) the
number of shares issued by FalconStor upon sale of its Series C Convertible
Preferred Stock to investors other than NPI, (3) the number of vested, in-the-
money options to purchase shares of NPI common stock outstanding at the time of
the Proposed Transaction and (4) the number of vested, in-the-money options to
purchase shares of FalconStor common stock outstanding at the time of the
Proposed Transaction. The terms and conditions of the Proposed Transaction are
set forth in more detail in the Option Agreement and the Agreement and Plan of
Merger and Reorganization between NPI and FalconStor (collectively, the
"Agreement").

We have been requested by the Board of Directors of the Company to render
our opinion with respect to the fairness, from a financial point of view, to
the Company of the Aggregate Consideration to be paid by the Company for the
FalconStor Equity in the Proposed Transaction. We have not been requested to
opine as to, and our opinion does not in any manner address, the Company's
underlying business decision to proceed with or effect the Proposed
Transaction.

In arriving at our opinion, we reviewed and analyzed: (1) the Agreement and
the specific terms of the Proposed Transaction, (2) publicly available
information concerning NPI that we believe to be relevant to our analysis,
including the Company's Annual Report on Form 10-K for the fiscal year ended
December 31, 1999 and the Company's Quarterly Reports on Form 10-Q for the
quarters ended March 31, June 30, and September 30, 2000 and the Company's
earnings release for the quarter and fiscal year ended December 31, 2000,
(3) financial and operating information with respect to the business,
operations and prospects of NPI furnished to us by NPI, including projections
for the next five years prepared by the management of the Company (the "Company
Projections"), (4) a trading history of the Company's common stock over the
past one year and five years, and a comparison of that trading history with
those of other companies that we deemed relevant, (5) financial and operating
information with respect to the business, operations and prospects of
FalconStor furnished to us by FalconStor, including projections for the next
three years prepared by the management of FalconStor (the "FalconStor
Projections"), (6) a comparison of the historical financial results and present
financial condition of the Company and FalconStor with those of other companies
that we deemed relevant, (7) a comparison of the financial terms of the
Proposed Transaction with the financial terms of certain

B-1

other transactions that we deemed relevant, (8) a possible liquidation of the
Company, including the cash that would be distributed to the Company's
stockholders in connection with such liquidation, and (9) the results of our
efforts to solicit indications of interest from third parties with respect to a
purchase of the Company or its operating business. In addition, we have had
discussions with the managements of FalconStor and NPI concerning the business,
operations, assets, financial condition and prospects of FalconStor (including
the FalconStor Projections) and discussions with the management of NPI
concerning its business, operation, assets, financial condition and prospects,
and have undertaken such other studies, analyses and investigations as we
deemed appropriate.

In arriving at our opinion, we have assumed and relied upon the accuracy and
completeness of the financial and other information used by us without assuming
any responsibility for independent verification of such information and have
further relied upon the assurances of management of the Company and FalconStor
that they are not aware of any facts or circumstances that would make such
information inaccurate or misleading. With respect to the Company Projections,
upon advice of the Company we have assumed that such projections have been
reasonably prepared on a basis reflecting the best currently available
estimates and judgments of the management of the Company as to the future
financial performance of the Company and that the Company will perform
substantially in accordance with the Company Projections. With respect to the
FalconStor Projections, upon advice of FalconStor and the Company we have
assumed that such projections have been reasonably prepared on a basis
reflecting the best currently available estimates and judgments of the
management of FalconStor as to the future financial performance of FalconStor
and that FalconStor will perform substantially in accordance with the
FalconStor Projections. In arriving at our opinion, we have not conducted a
physical inspection of the properties and facilities of FalconStor or the
Company and have not made or obtained any evaluations or appraisals of the
assets or liabilities of FalconStor or the Company. Our opinion necessarily is
based upon market, economic and other conditions as they exist on, and can be
evaluated as of, the date of this letter.

Based upon and subject to the foregoing, we are of the opinion as of the
date hereof that, from a financial point of view, the Aggregate Consideration
to be paid by the Company for the FalconStor Equity in the Proposed Transaction
is fair to the Company.

The Company has agreed to indemnify us for certain liabilities that may
arise out of the rendering of this opinion. We also have performed various
investment banking services for the Company in the past and have received
customary fees for such services. In the ordinary course of our business, we
actively trade in the securities of the Company for our own account and for the
accounts of our customers and, accordingly, may at any time hold a long or
short position in such securities.

This opinion is for the use and benefit of the Board of Directors of the
Company and is rendered to the Board of Directors in connection with its
consideration of the Proposed Transaction. This opinion is not intended to be
and does not constitute a recommendation to any stockholder of the Company as
to how such stockholder should vote with respect to the Proposed Transaction.

Very truly yours,

LEHMAN BROTHERS

ANNEX C

Delaware General Corporation Law, Section 262. APPRAISAL RIGHTS

(a) Any stockholder of a corporation of this State who holds shares of
stock on the date of the making of a demand pursuant to the provisions of
subsection (d) of this section with respect to such shares, who continuously
holds such shares through the effective date of the merger or consolidation,
who has otherwise complied with the provisions of subsection (d) of this
Section and who has neither voted in favor of the merger or consolidation nor
consented thereto in writing pursuant to Sec. 228 of this Chapter shall be
entitled to an appraisal by the Court of Chancery of the fair value of his
shares of stock under the circumstances described in subsections (b) and (c)
of this Section.

(b) Appraisal rights shall be available for the shares of any class or
series of stock or a constituent corporation in a merger or consolidation to
be effected pursuant to Secs. 251, 252, 254, 257, 258 or 263 of this title:

(1) Provided, however, that no appraisal rights under this section shall
be available for the shares of any class or series of stock which, at the
record date fixed to determine the stockholders entitled to receive notice
of and to vote at the meeting of stockholders to act upon the agreement of
merger or consolidation, were either (i) listed on a national securities
exchange or (ii) held of record by more than 2,000 stockholders; and
further provided that no appraisal rights shall be available for any shares
of stock of the constituent corporation surviving a merger if the merger
did not require for its approval the vote of the stockholders of the
surviving corporation as provided in subsection (f) of Sec. 251 of this
title.

(2) Notwithstanding paragraph (1) of this subsection, appraisal rights
under this section shall be available for the shares of any class or series
of stock of a constituent corporation if the holders thereof are required
by the terms of an agreement of merger or consolidation pursuant to Secs.
251, 252, 254, 257 and 258 of this title to accept for such stock anything
except:

a. Shares of stock of the corporation surviving or resulting from
such merger or consolidation;

b. Shares of stock of any other corporation which at the effective
date of the merger or consolidation will be either listed on a national
securities exchange or held of record by more than 2,000 stockholders;

c. Cash in lieu of fractional shares of the corporations described in
the foregoing subparagraphs a. and b. of this paragraph; or

d. Any combination of the shares of stock and cash in lieu of
fractional shares described in the foregoing subparagraphs a., b., and
c. of this paragraph.

(3) In the event all of the stock of a subsidiary Delaware corporation
party to a merger effected under Sec. 253 of this title is not owned by the
parent corporation immediately prior to the merger, appraisal rights shall
be available for the shares of the subsidiary Delaware corporation.

(c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets
of the corporation. If the certificate of incorporation contains such a
provision, the procedures of this section, including those set forth in
subsections (d) and (e) of this section, shall apply as nearly as is
practicable.

(d) Appraisal rights shall be perfected as follows:

(1) If a proposed merger or consolidation for which appraisal rights are
provided under this section is to be submitted for approval at a meeting of
stockholders, the corporation not less than 20 days prior to the meeting,
shall notify each of its stockholders entitled to such appraisal rights
that appraisal rights are available for any or all of the shares of the
constituent corporations, and shall include in such notice a copy of this
section. Each stockholder electing to demand the appraisal of his shares
shall deliver to the

C-1

corporation, before the taking of the vote on the merger or consolidation,
a written demand for appraisal of his shares. Such demand will be
sufficient if it reasonably informs the corporations of the identity of the
stockholder and that the stockholder intends thereby to demand the
appraisal of his shares. A proxy or vote against the merger or
consolidation shall not constitute such a demand. A stockholder electing to
take such action must do so by a separate written demand as herein
provided. Within 10 days after the effective date of such merger or
consolidation, the surviving or resulting corporation shall notify each
stockholder of each constituent corporation who has complied with this
subsection and has not voted in favor of or consented to the merger or
consolidation of the date that the merger or consolidation has become
effective; or

(2) If the merger or consolidation was approved pursuant to Sec. 228 or
253 of this title, the surviving or resulting corporation, either before
the effective date of the merger or consolidation or within 10 days
thereafter, shall notify each of the stockholders entitled to appraisal
rights of the effective date of the merger or consolidation and that
appraisal rights are available for any or all of the shares of the
constituent corporation, and shall include in such notice a copy of this
section. The notice shall be sent by certified or registered mail, return
receipt requested, addressed to the stockholder at his address as it
appears on the records of the corporation. Any stockholder entitled to
appraisal rights may, within 20 days after the date of mailing of the
notice, demand in writing from the surviving or resulting corporation the
appraisal of his shares. Such demand will be sufficient if it reasonably
informs the corporation of the identity of the stockholder and that the
stockholder intends to demand the appraisal of his shares.

(e) Within 120 days after the effective date of the merger or consolidation;
the surviving or resulting corporation or any stockholder who has complied with
subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholders. Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger or
consolidation, any stockholder shall have the right to withdraw his demand for
appraisal and to accept the terms offered upon the merger or consolidation.
Within 120 days after the effective date of the merger or consolidation, any
stockholder who has complied with the requirements of subsections (a) and (d)
hereof, upon written request, shall be entitled to receive from the corporation
surviving the merger or resulting from the consolidation a statement setting
forth the aggregate number of shares not voted in favor of the merger or
consolidation and with respect to which demands for appraisal have been
received and the aggregate number of holders of such shares. Such written
statement shall be mailed to the stockholder within 10 days after his written
request for such a statement is received by the surviving or resulting
corporation or within 10 days after expiration of the period for delivery of
demands for appraisal under subsection (d) hereof, whichever is later.

(f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the
addresses therein stated. Such notice shall also be given by 1 or more
publications at least 1 week before the day of the hearing, in a newspaper of
general circulation published in the City of Wilmington, Delaware or such
publication as the Court deems advisable. The forms of the notices by mail and
by publication shall be approved by the Court, and the costs thereof shall be
borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled
to appraisal rights. The Court may require the stockholders who have demanded
an appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock of the Register in Chancery for notation
thereon of the pendency of the appraisal

C-2

proceedings; and if any stockholder fails to comply with such direction, the
Court may dismiss the proceedings as to such stockholder.

(h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any
element of value arising from the accomplishment or expectation of the merger
or consolidation, together with a fair rate of interest, if any, to be paid
upon the amount determined to be the fair value. In determining such fair
value, the Court shall take into account all relevant factors. In determining
the fair rate of interest, the Court may consider all relevant factors,
including the rate of interest which the surviving or resulting corporation
would have had to pay to borrow money during the pendency of the proceeding.
Upon application by the surviving or resulting corporation or by any
stockholder entitled to participate in the appraisal proceeding, the Court may,
in its discretion, permit discovery or other pretrial proceedings and may
proceed to trial upon the appraisal prior to the final determination of the
stockholder entitled to an appraisal. Any stockholder whose name appears on the
list filed by the surviving or resulting corporation pursuant to subsection (f)
of this section and who has submitted his certificate of stock to the Register
in Chancery, if such is required, may participate fully in all proceedings
until it is finally determined that he is not entitled to appraisal rights
under this section.

(i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to
the stockholders entitled thereto. Interest may be simple or compound, as the
Court may direct. Payment shall be so made to each such stockholder, in the
case of holders of uncertificated stock forthwith, and in the case of holders
of shares represented by certificates upon the surrender to the corporation of
the certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

(k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall
deliver to the surviving or resulting corporation a written withdrawal of his
demand for an appraisal and an acceptance of the merger or consolidation,
either within 60 days after the effective date of the merger or consolidation
as provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the
Court of Chancery shall be dismissed as to any stockholder without the approval
of the Court, and such approval may be conditioned upon such terms as the Court
deems just.

(l) The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders would have been converted had they assented to
the merger or consolidation shall have the status of authorized and unissued
shares of the surviving or resulting corporation.

C-3

ANNEX D

FORM OF NPI LOCK-UP AGREEMENT

May , 2001

FalconStor, Inc.
125 Baylis Road, Suite 140
Melville, NY 11747

and wholly-owned subsidiary of NPI ("MergerSub") and FalconStor, Inc., a
Delaware corporation ("FSI"), it is contemplated that MergerSub will merge with
and into FSI, with FSI surviving as the continuing entity and that all of the
outstanding common stock of FSI ("FSI Common Stock") will be converted into the
right to receive shares of the common stock of NPI ("NPI Common Stock"), as set
forth in the Agreement (the "Merger").

It is a condition precedent to the consummation of the Merger, that the
undersigned stockholder of NPI, who is the record or beneficial owner of more
than 30,000 shares of the common stock of NPI (the "Shares"), enter into this
letter agreement with FalconStor, whereby the undersigned agrees that, in order
to induce FSI to enter into the Agreement, he or she, during the period
commencing on the date hereof and ending 365 days after the effective date of
the Merger (the "Lock-Up Period") shall not, directly or indirectly sell, offer
to sell, contract to sell (including, without limitation, any short sale),
grant any option to purchase or otherwise transfer or dispose of (other than to
donees who agree to be similarly bound) any of his or her Shares; provided,
however, that this letter agreement shall have no force or effect unless, each
officer and director of FalconStor and each stockholder who is an affiliate of
such employee, officer or director (as that term is defined in Rule 405
promulgated under the Securities Act of 1933, as amended) executes a similar
letter agreement.

If the undersigned is terminated by NPI without Cause or voluntarily resigns
for Good Reason after the execution and delivery of the Agreement by NPI and
FSI, then his or her Shares will be released from the obligations of this
letter agreement prior to the expiration of the Lock-Up Period.

For purposes of this letter agreement, "Cause" is defined as a termination
for any of the following reasons: (i) theft, dishonesty or falsification of any
employment or NPI records; (ii) conviction of a felony or any act involving
moral turpitude; (iii) the undersigned's intentional failure or refusal to
perform duties reasonably assigned to him or her by the Board of Directors or
Chief Executive Officer of NPI within 10 days of the undersigned's receipt of
written notice from NPI; (iv) disclosure of NPI's confidential or proprietary
information; (v) the undersigned becomes unable to perform the essential
functions or duties of his position with or without reasonable accommodations;
(vi) any conduct by the undersigned that has a detrimental effect on NPI's
reputation or business, or is otherwise detrimental to NPI; (vii) any material
breach of this letter agreement; or (viii) NPI ceases to do business or files
for bankruptcy.

For purposes of this letter agreement, "Good Reason" is defined as (i) NPI's
material breach of this letter agreement; (ii) the undersigned's base salary
being reduced by more than 20% below his or her salary in effect immediately
following the Merger, unless the reduction is made as part of, and is generally
consistent with, a general reduction of salaries; or (iii) the undersigned's
position and/or duties are so modified that the undersigned's duties are no
longer consistent with his or her position immediately following the Merger.

The undersigned hereby represents and warrants that the undersigned has full
power and authority to execute this letter and enter the agreements set forth
herein, and that, upon request, the undersigned will execute any additional
documents necessary or desirable in connection with the enforcement hereof.

D-1

All authority herein conferred or agreed to be conferred shall survive the
death or incapacity of the undersigned and any obligations of the undersigned
shall be binding upon the heirs, personal representatives, successors, and
assigns of the undersigned. In the event that the Merger shall not have
occurred on or before , 2001 this letter shall be of no
further force or effect.

Very truly yours,

WHEREAS, NPI has agreed to provide Twenty Five Million Dollars ($25,000,000)
of capital to FalconStor in the form of an equity investment (the "Equity
Investment").

WHEREAS, contemporaneously with the execution of this Agreement, NPI and
FalconStor are entering into and executing stock purchase and related
agreements, including a registration rights agreement and an investors' rights
agreement, to consummate the Equity Investment (the "Equity Investment
Agreements").

WHEREAS, NPI and FalconStor have negotiated the terms upon which NPI
proposes to enter into discussions to (i) invest in FalconStor, (ii) engage in
a series of transactions whereby a wholly owned subsidiary of NPI will merge
with and into FalconStor with FalconStor surviving as the continuing entity
(the "Merger Transaction") and (iii) resolve certain other related matters.

WHEREAS, a substantial and material inducement to NPI to consummate the
Equity Investment is the grant by FalconStor to NPI of an option to execute the
Merger Transaction and FalconStor's execution and delivery of this Agreement
and the execution and delivery of the Voting Agreement (as defined below).

NOW, THEREFORE, for good and valuable consideration, including the execution
and delivery of the Equity Investment Agreements, the receipt and sufficiency
of which is hereby acknowledged, the parties hereto agree as follows:

Section 1. Option to Merge with FalconStor. FalconStor hereby grants to NPI,
and NPI accepts, an option to execute the Merger Transaction on the terms set
forth in the Merger Agreement (as defined below) (the "Option"). The Option
shall be irrevocable during the term of this Agreement and may be exercised by
delivery of written notice to FalconStor of such exercise; provided, however,
that the Option shall only be exercisable during the 14-day period (the
"Exercise Period") immediately following (i) written notice by FalconStor to
NPI of the issuance and sale of additional shares of Series C Convertible
Preferred Stock (the "Series C Sale"), or (ii) four (4) weeks from the date of
this Agreement, whichever occurs first, unless extended by the written consent
of FalconStor and NPI. In the event of a Series C Sale, FalconStor shall
deliver a notice within twenty-four (24) hours to NPI notifying NPI of such
sale. Immediately upon exercise of the Option, the parties hereto will, acting
at all times in good faith, take, or cause to be taken, all actions and do, or
cause to be done, all things necessary, proper or advisable under applicable
laws and regulations to execute and deliver a definitive agreement (the "Merger
Agreement") to consummate the Merger Transaction on the terms set forth in the
form of merger agreement attached hereto as Exhibit A as promptly as
practicable after the date on which NPI exercises the Option, including (i)
taking all corporate actions necessary to authorize, approve and direct the
execution and delivery of the Merger Agreement, (ii) authorizing and directing
their executive officers, accountants and legal counsel to devote all necessary
resources, utilizing their best efforts, to achieve the execution and delivery
of the Merger Agreement, (iii) preparing and filing as promptly as practicable
all documentation to effect all necessary applications, notices, petitions,
filings and other documents and to obtain as promptly as practicable all third
party consents and all consents necessary or advisable to be obtained from any
governmental entity in order to execute and deliver the Merger Agreement, (iv)
taking all reasonable steps as may be necessary to obtain all such third party
consents and consents of governmental entities necessary or advisable to be
obtained from any governmental entity in order to execute and deliver the
Merger Agreement

F-1

and (v) defending any actions challenging this Agreement or the Merger
Agreement or the transactions contemplated hereby or thereby, including seeking
to have any stay or temporary restraining order entered by any governmental
entity vacated or reversed.

Section 2. Other Negotiations. During the term of this Agreement, neither
NPI nor FalconStor will (and it will use its best efforts to ensure that its
officers, directors, employees, agents and affiliates do not on its behalf)
take any action to solicit, initiate, seek, encourage or support any inquiry,
proposal or offer from, furnish any information to, or participate in any
negotiations with, any corporation, partnership, person or other entity or
group (each, a "Person") (other than discussions with the other party hereto)
regarding any acquisition of such party, any merger or consolidation with such
party, or any acquisition of all or substantially all of the stock or assets of
such party, (an "Acquisition Proposal"); provided, however, that if, at any
time during the term of this Agreement, the Board of Directors of either party
by majority vote determines in good faith, after receiving advice from its
outside counsel, that failing to take such action would constitute a breach of
the fiduciary duties of the such Board of Directors, such party may, in
response to a bona fide written Acquisition Proposal which did not result from
a breach of this Section 2 and which such Board of Directors determines in its
reasonable judgment, to be more favorable to its stockholders (taking into
account, among other things, all legal, financial, regulatory and other aspects
of the proposal and identity of the offeror) as compared to the transactions
contemplated by the Merger Agreement and which is reasonably capable of being
consummated ("Superior Proposal"); provided, however, that any such offer shall
not be deemed to be a Superior Proposal if any financing required to consummate
the transaction contemplated by such offer is not committed and is not
reasonably capable of being obtained by such third party, (i) furnish
information or provide access with respect to such party and each of its
subsidiaries to such Person pursuant to a customary confidentiality agreement
(as determined by such party after consultation with its outside counsel) and
(ii) participate in discussions and negotiations regarding such Superior
Proposal (it being understood that neither the sale and issuance by FalconStor
of additional shares of its Series C Convertible Preferred Stock nor the sale
by NPI of any Assets, as defined in the Letter Agreement dated March 21, 2001
by and between NPI and FalconStor, shall breach or violate the terms of this
Agreement). Each of NPI and FalconStor agrees that any such negotiations in
progress as of the date hereof will be terminated or suspended until this
Agreement is terminated pursuant to Section 5. Each party hereto will
immediately notify the other party hereto regarding any contact by any third
party regarding any offer, proposal or inquiry regarding any Acquisition
Proposal. In no event will either party hereto accept or enter into an
agreement concerning any such third party transaction prior to the Termination
of this Agreement pursuant to Section 5. Each party hereto represents and
warrants that it has the legal right to terminate or suspend any such pending
negotiations and agrees to indemnify the other party hereto, its
representatives and agents from and against any claims by any party to such
negotiations based upon or arising out of the discussion or any consummation of
the transactions contemplated by this Agreement.

notice or lapse of time or both) a default (or give rise to any right of
termination, amendment, cancellation or acceleration) under, any of the
terms, conditions or provisions of any note, bond, mortgage, indenture,
lease, license, contract, agreement or other instrument or obligation to
which NPI is a party or by which any of its properties or assets may be
bound, or (iii) violate any order, writ, injunction, decree, judgment,

and FalconStor.

d. In the event that (i) the Option is not exercised timely or (ii) the
Merger Agreement is not executed and delivered by both FalconStor and NPI

Option is exercised within the first seven (7) days of the Exercise Period
or (B) if the Option is exercised with the second seven (7) days of the
Exercise Period within the period starting on the

F-3

date the Option is exercised and ending seven (7) days after the Exercise
Period terminates, FalconStor, by action of its Board of Directors, shall
have the right to terminate this Agreement under this Section 5(d)
(provided that such termination of this Agreement under Section 5(d) is not
due to FalconStor's failure to fulfill any obligation under this Agreement
has been the cause of or resulted in the failure of the Merger Agreement to
be executed and delivered by FalconStor by such date).

e. In the event that this Agreement terminates pursuant to Section 5(d)
(provided that such termination of this Agreement under Section 5(d) is not
due to FalconStor's failure to fulfill any obligation under this Agreement
has been the cause of or resulted in the failure of the Merger Agreement to
be executed and delivered by FalconStor by such date) then (i) NPI hereby
covenants to vote all shares of preferred stock purchased by NPI pursuant
to the Equity Investment Agreements in accordance with the recommendation
of the Board of Directors of FalconStor, other than in respect of a
Disposition Transaction (as that term is defined in the Certificate of
Designations of the Series C Convertible Preferred Stock of FalconStor) in
which case NPI shall vote as it deems appropriate and (ii) NPI shall
concurrently (or on the following business day) pay to FalconStor a
termination fee of $3 Million.

f. In the event this Agreement is terminated pursuant to Section 5, this
Agreement shall immediately become void and there shall be no liability or
obligation on the part of NPI and FalconStor or their respective officers,
directors, stockholders or affiliates except to the extent that the
termination is a result of a willful and material breach by a party to this
Agreement of any representation, warranty or covenant contained in this
Agreement; provided, however, that the provisions of Section 6(k) and the
obligations of NPI under Section 5(e) shall remain in full force and effect

ANNEX G

Network Peripherals Inc.

CHARTER OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

I. Purpose

The purpose of the Audit Committee (the "Committee") of the Board of
Directors (the "Board") of Network Peripherals Inc. (the "Company") is to
assist the Board in fulfilling its statutory and fiduciary oversight
responsibilities relating to the Company's financial accounting, reporting and
controls. The Committee's principal functions are to:

. monitor the periodic reviews of the adequacy of the accounting and
financial reporting processes and systems of internal control that are
conducted by the Company's independent auditors, and the Company's
financial and senior management;

. review and evaluate the independence and performance of the Company's
independent auditors; and

. facilitate communication among the Company's independent auditors, the
Company's financial and senior management, and the Board.

The Committee will fulfill these functions primarily by carrying out the
activities enumerated in Part IV of this charter. In order to serve these
functions, the Committee shall have unrestricted access to Company personnel
and documents, and shall have authority to direct and supervise an
investigation into any matters within the scope of its duties, including the
power to retain outside counsel in connection with any such investigation.

While the Audit Committee has the responsibilities and powers set forth in
this charter, it is not the duty of the Committee to plan or conduct audits or
to determine that the Company's financial statements are complete and accurate
and are in accordance with generally accepted accounting principles. This is
the responsibility of management and the Company's independent auditors. Nor is
it the duty of the Committee to conduct investigations, to resolve
disagreements, if any, between management and its independent auditors or to
assure compliance with laws and regulations and the Company's policies and
procedures.

II. Membership

All members of the Committee will be appointed by, and shall serve at the
discretion of, the Board. Unless a chair is elected by the full Board, the
members of the Committee may designate a Chair by majority vote of the
Committee membership.

As of the date this charter is adopted and until June 13, 2001, the
Committee shall consist of at least two members of the Board. At least a
majority of the members shall be persons who are not officers or employees of
the Company or any subsidiary and who do not have any other relationship which,
in the opinion of the Board of Directors, would interfere with the exercise of
independent judgment in carrying out the responsibilities of a director. As of
June 14, 2001, the Committee shall consist of three or more members of the
Board, with the exact number being determined by the Board. Each member of the
Committee shall be "independent" as defined by the rules of The Nasdaq Stock
Market, as they may be amended from time to time (the "Rules"), except as
otherwise permitted by such Rules. Each member of the Committee shall have the
ability to read and understand fundamental financial statements (or become able
to do so within a reasonable time after joining the Committee) and at least one
member shall have prior experience in accounting, financial management or
financial oversight, as required by the Rules.

G-1

III. Meetings

Meetings of the Committee shall be held from time to time as determined by
the Board. The Committee should periodically meet with the independent auditors
out of the presence of management about internal controls, the fullness and
accuracy of the Company's financial statements and any other matters that the
Committee or these groups believe should be discussed privately with the
Committee. The Committee members should communicate with management and the
independent auditors on a quarterly basis in connection with their review of
the Company's financial statements.

IV. Responsibilities and Duties

The following shall be the principal recurring processes of the Committee in
carrying out its oversight responsibilities. These processes are set forth as a
guide with the understanding that the Committee may supplement them as
appropriate and may establish policies and procedures from time to time that it
deems necessary or advisable in fulfilling its responsibilities.

1. Review the Company's quarterly and annual financial statements, including
any report or opinion by the independent auditors, prior to distribution to the
public or filing with the Securities and Exchange Commission.

2. In connection with the Committee's review of the annual financial
statements:

. Discuss with the independent auditors and management the financial
statements and the results of the independent auditors' audit of the
financial statements.

. Discuss any items requiring communication by the independent auditors in
accordance with SAS 61, as amended. These discussions should include the
independent auditors' judgments about the quality and appropriateness of
the Company's accounting principles, the reasonableness of significant
judgments, the clarity of the disclosures in the Company's financial
statements and any significant difficulties encountered during the
course of the audit, including any restrictions on the scope of work or
access to required information.

3. In connection with the Committee's review of the quarterly financial
statements:

. Discuss with the independent auditors and management the results of the
independent auditors' SAS 71 review of the quarterly financial
statements.

. Discuss significant issues, events and transactions and any significant
changes regarding accounting principles, practices, judgments or
estimates with management and the independent auditors, including any
significant disagreements among management and the independent auditors.

4. Discuss any comments or recommendations of the independent auditors
outlined in their annual management letter. Approve a schedule for implementing
any recommended changes and monitor compliance with the schedule.

5. Discuss with the independent auditors and management their periodic
reviews of the adequacy of the Company's accounting and financial reporting
processes and systems of internal control, including the adequacy of the
systems of reporting to the audit committee by each group.

6. Periodically consult with the independent auditors out of the presence of
management about internal controls, the fullness and accuracy of the Company's
financial statements and any other matters that the Committee or these groups
believe should be discussed privately with the Committee.

7. Review the independence and performance of the independent auditors.
Recommend to the Board of Directors the appointment or discharge of the
independent auditors.

G-2

8. Communicate with the Company's independent auditors about the Company's
expectations regarding its relationship with the auditors, including the
following: (i) the independent auditors' ultimate accountability to the Board
and the Committee, as representatives of the Company's stockholders; and (ii)
the ultimate authority and responsibility of the Board and the Committee to
select, evaluate and, where appropriate, replace the independent auditors.

9. Review and approve processes and procedures to ensure the continuing
independence of the Company's independent auditors.

10. Review the independent auditors' audit plan.

11. Approve the fees and other significant compensation to be paid to the
independent auditors.

12. Periodically review the status of any legal matters that could have a
significant impact on the Company's financial statements.

13. Annually prepare a report to the Company's stockholders for inclusion
in the Company's annual proxy statement as required by the rules and
regulations of the Securities and Exchange Commission, as they may be amended
from time to time.

14. Maintain minutes of meetings and periodically report to the Board of
Directors on significant matters related to the Committee's responsibilities.

15. Review and reassess the adequacy of the Committee's charter at least
annually. Submit the charter to the Company's Board of Directors for review and
include a copy of the charter as an appendix to the Company's proxy statement
as required by the rules and regulations of the Securities and Exchange
Commission, as they may be amended from time to time (currently, once every
three years).

16. Perform any other activities required by applicable law, rules or
regulations, including the rules of the Securities and Exchange Commission and
any stock exchange or market on which the Company's Common Stock is listed, and
perform other activities that are consistent with this charter, the Company's
Bylaws and governing laws, as the Committee or the Board deems necessary or
appropriate.
