                                  COMMON STOCK

         This prospectus relates to the shares of our common stock issuable upon
exchange or redemption of the exchangeable shares of 892489 Alberta Inc., one of
our wholly owned Canadian subsidiaries that we call PTI HoldCo in this
prospectus. The exchangeable shares were issued to the former shareholders of
PTI Group Inc. who are residents of Canada and who elected to receive
exchangeable shares in connection with our acquisition of PTI Group. Each
exchangeable share may be exchanged for one share of our common stock, plus all
payable and unpaid dividends, if any, on an exchangeable share and on a share of
our common stock. Because the shares of our common stock offered by this
prospectus will be issued only in exchange for, or upon the redemption of, the
exchangeable shares, we will not receive any cash proceeds from this offering.
We are paying all expenses of registration incurred in connection with this
offering.

         Our common stock is listed on the New York Stock Exchange, or NYSE,
under the trading symbol "OIS." On March 1, 2002, the last reported sale price
of our common stock on the NYSE was $9.25 per share.

                                   ----------

         Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved of these securities or passed upon the
adequacy and accuracy of this prospectus. Any representation to the contrary is
a criminal offense.

         This prospectus constitutes part of the registration statement on Form
S-3 filed with the SEC under the Securities Act of 1933 utilizing a "shelf"

                         OIL STATES INTERNATIONAL, INC.

         We are a leading provider of specialty products and services to oil and
gas drilling and production companies throughout the world. We focus our
business and operations in a substantial number of the world's most active and
fastest growing oil and gas producing regions, including the Gulf of Mexico,
Canada, West Africa, the Middle East, South America and Southeast Asia. Our
customers include many of the major and independent oil and gas companies and
other oilfield service companies. We operate in three principal business
segments, offshore products, tubular services and well site services, and have
established a leadership position in each.

OFFSHORE PRODUCTS

Overview

         Through our offshore products segment, we design and manufacture
cost-effective, technologically advanced products for the offshore energy
industry. Our products are used in both shallow and deepwater producing regions
and include flex-element technology, advanced connector systems, blow-out
preventor stack integration and repair services, offshore equipment and
installation services and subsea pipeline products. We have facilities in
Arlington, Houston and Lampasas, Texas; Houma, Louisiana; Scotland; Brazil;
England and Singapore.

Products and Services

         Our offshore products segment provides a broad range of products and
services for use in offshore drilling and development activities. In addition,
this segment provides onshore oil and gas, defense and general industrial
products and services. Our offshore products segment is dependent on continuing
innovation and creative applications of existing technologies.

         We design and build manufacturing and testing systems for many of our
new products and services. These testing and manufacturing facilities enable us
to provide reliable, technologically advanced products and services. Our
Aberdeen facility provides a wide range of structural testing including
full-scale product simulations.

         We design, manufacture, fabricate, inspect, assemble, repair, test and
market subsea equipment and offshore vessel and rig equipment. Our products are
components of equipment used on marine vessels, floating rigs and jack-ups, and
for the drilling and production of oil and gas wells on offshore fixed platforms
and mobile production units including floating platforms and FPSO vessels. Our
products and services include:

o        flexible bearings and connector products;

o        subsea pipeline products;

o        marine winches, mooring systems and rig equipment;

o        blowout preventor stack assembly, integration, testing and repair
         services; and

                                       3


TUBULAR SERVICES

Overview

         Through our tubular services segment, we distribute oil country tubular
goods, or OCTG, and are a provider of associated OTCG finishing and logistics
services to the oil and gas industry. Oil country tubular goods consist of
casing, production tubing and line pipe. Through our tubular services segment,
we:

         o        distribute premium tubing and casing;

         o        provide threading, remediation, logistical and inventory
                  services; and

         o        offer e-commerce pricing, ordering and tracking capabilities.

         We serve a customer base, ranging from major oil companies to small
independents. Through our key relationships with more than 20 manufacturers of
oilfield specialty pipe, we deliver tubular products and ancillary services to
oil and gas companies, drilling contractors and consultants around the world.
The OCTG distribution market is highly fragmented and competitive, and is
predominately focused in the United States. Despite being a leading distributor
of OCTG, we estimate that our U.S. market share is approximately 15%.

Products and Services

         Tubular Products and Services. We distribute various types of OCTG
produced by both domestic and foreign manufacturers to major and independent oil
and gas exploration and production companies and other OCTG distributors. We do
not manufacture any of the tubular goods that we distribute. As a result, gross
margins in this segment are generally lower than those reported by our other
segments. We operate our tubular services segment from a total of 11 facilities
and have offices located near areas of oil and gas exploration and development
activity predominately in the United States, and to a lesser extent, in Scotland
and Nigeria. Our business in Scotland and Nigeria is expected to change and
likely to decline as a result of the completion of a contract with a major
customer in these areas. We currently have interim inventory management
contracts that extend to March 31, 2002 in Nigeria and June 30, 2002 in
Scotland. There can be no assurance that such interim contracts will be extended
beyond these dates. See Management's Discussion and Analysis of Financial
Condition and Results of Operations included in our Annual Report on Form 10-K
for the year ended December 31, 2001, which is incorporated by reference herein.

         In this business, inventory management is critical to our success. We
maintain on-the-ground inventory in more than 75 yards located in the United
States, giving us the flexibility to fill our customers' orders from our own
stock or directly from the manufacturer. We have a proprietary inventory
management system, designed specifically for the OCTG industry, that enables us
to track our product shipments down to the individual pipe stem.

         A-Z Terminal. Our A-Z Terminal pipe maintenance and storage facility in
Crosby, Texas is equipped to provide a full range of tubular services, giving us
strong customer service capabilities. The A-Z Terminal is set on 109 acres and
is an ISO 9002-certified facility. A-Z Terminal has more than 1,400 pipe racks
and two double-ended thread lines. We have exclusive use of a permanent
third-party inspection center within the facility. The facility also includes
indoor chrome storage capability and patented pipe cleaning machines.

         We offer services at our A-Z Terminal facility typically outsourced by
other distributors, including the following: threading, inspection, cleaning,
cutting, logistics, rig returns, installation of float equipment and
non-destructive testing.

Regions of Operations

         Our tubular services segment provides tubular products and services to
customers in the United States, the Gulf of Mexico, Canada, Nigeria, Venezuela,
Ecuador, Colombia, Guatemala and the United Kingdom. However, the majority of
our sales are made in the United States, both for land and offshore
applications.

abandonment stages of the well. Our hydraulic workover units are used for
workover operations and snubbing operations in pressure situations.

         Drilling Services. Our drilling services business is located in Odessa,
Texas and Wooster, Ohio and provides drilling services for shallow to medium
depths ranging from 2,000 to 9,000 feet. Drilling services are typically used
during the exploration and development stages of a field. We have a total of 12
semi-automatic drilling rigs with hydraulic pipe handling booms and lift
capacities ranging from 200,000 to 300,000 pounds. Nine of these drilling rigs
are located in Odessa, Texas and three are located in Wooster, Ohio. As of March
1, 2002, 8 rigs were working or under contract.

         Rental Services. Our rental services business provides a wide range of
products for use in the offshore and onshore oil and gas industry, including:

         o        wireline and coiled tubing pressure control equipment;

         o        pipe recovery systems; and

         o        surface-based pressure control equipment used in production
                  operations.

Our rental services are used during the exploration, development, production and
abandonment stages. We provide rental services at 15 U.S. distribution points in
Texas, Louisiana, Oklahoma, Mississippi and New Mexico.

         Remote Site Accommodations, Catering and Logistics and Modular Building
Construction. We are a leading provider of fully integrated products and
services required to support a workforce at a remote location, including
workforce accommodations, food services, remote site management services and
modular building construction. We provide complete design, manufacture,
installation, operation and redeployment logistics services for oil and gas
drilling, oil sands mining, diamond mining, pipeline construction, offshore
construction, disaster relief services or any other industry that requires
remote site logistics projects. Our remote site products and services operations
are primarily focused in Canada and the Gulf of Mexico. During the peak of our
operating season, we typically provide logistics services in over 200 separate
locations throughout the world to remote sites with populations ranging from 20
to 2,000 persons.

         Remote Site Accommodations, Catering and Logistics Services. We sell
and lease portable living quarters, galleys, diners and offices and provide
portable generators, water sewage systems and catering services as part of our
remote site logistics services. We provide various client-specific building
configurations to customers for use in both onshore and offshore applications.
We provide our integrated remote site logistics services to customers under
long-term and short-term contractual arrangements.

for any forward-looking statement made by us, or on our behalf. The factors
identified in this cautionary statement are important factors (but not
necessarily all of the important factors) that could cause actual results to
differ materially from those expressed in any forward-looking statement made by
us, or on our behalf. Such statements are "forward-looking statements." You can
typically identify forward-looking statements by the use of forward-looking
words such as "may," "will," "could," "project," "believe," "anticipate,"
"expect," "estimate," "potential," "plan," "forecast," and other similar words.
All statements other than statements of historical facts contained in this
prospectus, including statements regarding our future financial position,
budgets, projected costs and plans and objectives of management for future
operations, are forward-looking statements. Where any such forward-looking
statement includes a statement of the assumptions or bases underlying such
forward-looking statement, we caution that, while we believe such assumptions or
bases to be reasonable and make them in good faith, assumed facts or bases
almost always vary from actual results. The differences between assumed facts or
bases and actual results can be material, depending upon the circumstances.

         Where, in any forward-looking statement, Oil States, or our management,
expresses an expectation or belief as to the future results, such expectation or
belief is expressed in good faith and believed to have a reasonable basis.
However, there can be no assurance that the statement of expectation or belief
will result, or be achieved or accomplished. Taking this into account, the
following are identified as important risk factors that could cause actual
results to differ materially from those expressed in any forward-looking
statement made by, or on behalf of, Oil States.

Risk Related to the Exchangeable Shares

THE EXCHANGE OF YOUR EXCHANGEABLE SHARES IS GENERALLY TAXABLE.

         Based on the tax laws as of the date of this prospectus, the exchange
or redemption of exchangeable shares is generally a taxable event in Canada and
may be a taxable event in the United States. Your tax consequences depend on a
number of factors, which are discussed in more detail under the caption "Income
Tax Considerations."

Risks Related to Oil States' Business Generally

DECREASED OIL AND GAS INDUSTRY EXPENDITURE LEVELS WILL ADVERSELY AFFECT OUR
RESULTS OF OPERATIONS.

         We depend upon the oil and gas industry and its willingness to make
expenditures to explore for, develop and produce oil and gas. If these
expenditures decline, our business will suffer. The industry's willingness to
explore, develop and produce depends largely upon the prevailing view of future
product prices. Many factors affect the supply and demand for oil and gas and
therefore influence product prices, including:

         o        the level of production;

         o        the levels of oil and gas inventories;



                                       6


         o        the expected cost of developing new reserves;

         o        the cost of producing oil and gas;

         o        the level of drilling activity;

         o        worldwide economic activity;

         o        national government political requirements, including the
                  ability of the Organization of Petroleum Exporting Companies
                  (OPEC) to set and maintain production levels and prices for
                  oil;

         o        the cost of developing alternate energy sources;

         o        environmental regulation; and

         o        tax policies.

If demand for drilling services, cash flows of drilling contractors or drilling
rig utilization rates decrease significantly, then demand for our products and
services will decrease.

EXTENDED PERIODS OF LOW OIL PRICES MAY DECREASE DEEPWATER EXPLORATION AND
PRODUCTION ACTIVITY AND ADVERSELY AFFECT OUR BUSINESS.

         Our offshore products segment depends on exploration and production
expenditures in deepwater areas. Because deepwater projects are more capital
intensive and take longer to generate first production than shallow water and
onshore projects, the economic analyses conducted by exploration and production
companies typically assume lower prices for production from such projects to
determine economic viability over the long term. If oil prices remain near or
below those levels used to determine economic viability for an extended period
of time, deepwater activity and our business will be adversely affected.

BECAUSE THE OIL AND GAS INDUSTRY IS CYCLICAL, OUR OPERATING RESULTS MAY
FLUCTUATE.

         Oil prices have been volatile over the last three years, ranging from
less than $11 per barrel to over $37 per barrel. Spot gas prices have also been
volatile, ranging from less than $1.25 per MMBtu to above $10.00 per MMBtu.
These price changes have caused oil and gas companies and drilling contractors
to change their strategies and expenditure levels. Oil States, Sooner, HWC and
PTI have experienced in the past, and we may experience in the future,
significant fluctuations in operating results based on these changes.

WE MIGHT BE UNABLE TO COMPETE SUCCESSFULLY WITH OTHER COMPANIES IN OUR INDUSTRY.

         We sell our products and services in competitive markets. In some of
our business segments, we compete with the oil and gas industry's largest
oilfield services providers. These companies have greater financial resources
than we do. In addition, our business, particularly our tubular services
business, may face competition from Internet business-to-business service
providers. We expect the number of these providers to increase in the future.
Our business will be adversely affected to the extent that these providers are
successful in reducing purchases of our products and services.

         Our operations may be adversely affected if our current competitors or
new market entrants introduce new products or services with better prices,
features, performance or other competitive characteristics than our products and
services. Competitive pressures or other factors also may result in significant
price competition that could have a material adverse effect on our results of
operations and financial condition.




                                       7





DISRUPTIONS IN THE POLITICAL AND ECONOMIC CONDITIONS OF THE FOREIGN COUNTRIES IN
WHICH WE OPERATE COULD ADVERSELY AFFECT OUR BUSINESS.

         We have operations in various international areas, including parts of
West Africa and South America. Our operations in these areas increase our
exposure to risks of war, local economic conditions, political disruption, civil
disturbance and governmental policies that may:

         o        disrupt our operations;

         o        restrict the movement of funds or limit repatriation of
                  profits;

         o        lead to U.S. government or international sanctions; and

         o        limit access to markets for periods of time.

Some areas, including West Africa and parts of South America, have experienced
political disruption in the past. Disruptions may occur in the future in our
foreign operations, and losses caused by these disruptions may occur that will
not be covered by insurance.

WE ARE SUSCEPTIBLE TO SEASONAL EARNINGS VOLATILITY DUE TO ADVERSE WEATHER
CONDITIONS IN OUR REGIONS OF OPERATIONS.

         Our operations are directly affected by seasonal differences in weather
in the areas in which we operate, most notably in Canada and the Gulf of Mexico.
Our Canadian remote site logistics operations are significantly focused on the
winter months when the winter freeze in remote regions permits exploration and
production activity to occur. The spring thaw in these frontier regions
restricts operations in the spring months and, as a result, adversely affects
our operations and sales of products and services in the second and third
quarters. Our operations in the Gulf of Mexico are also affected by weather
patterns. Weather conditions in the Gulf Coast region generally result in higher
drilling activity in the spring, summer and fall months with the lowest activity
in the winter months. In addition, summer and fall drilling activity can be
restricted due to hurricanes and other storms prevalent in the Gulf of Mexico
and along the Gulf Coast. As a result, full year results are not likely to be a
direct multiple of any particular quarter or combination of quarters.

WE MIGHT BE UNABLE TO EMPLOY A SUFFICIENT NUMBER OF TECHNICAL PERSONNEL.

         Many of the products that we sell, especially in our offshore products
segment, are complex and highly engineered and often must perform in harsh
conditions. We believe that our success depends upon our ability to employ and
retain technical personnel with the ability to design, utilize and enhance these
products. In addition, our ability to expand our operations depends in part on
our ability to increase our skilled labor force. The demand for skilled workers
is high, and the supply is limited. A significant increase in the wages paid by
competing employers could result in a reduction of our skilled labor force,
increases in the wage rates that we must pay or both. If either of these events
were to occur, our cost structure could increase and our growth potential could
be impaired.

IF WE DO NOT DEVELOP NEW COMPETITIVE TECHNOLOGIES AND PRODUCTS, OUR BUSINESS AND
REVENUES MAY BE ADVERSELY AFFECTED.

         The market for our offshore products is characterized by continual
technological developments to provide better performance in increasingly greater
depths and harsher conditions. If we are not able to design, develop and produce
commercially competitive products in a timely manner in response to changes in
technology, our business and revenues will be adversely affected.

THE LEVEL AND PRICING OF TUBULAR GOODS IMPORTED INTO THE UNITED STATES COULD
DECREASE DEMAND FOR OUR TUBULAR GOODS INVENTORY AND ADVERSELY IMPACT OUR RESULTS
OF OPERATIONS.

         U.S. law currently restricts imports of low-cost tubular goods from a
number of foreign countries into the U.S. tubular goods market, resulting in
higher prices for tubular goods. If these restrictions were to be lifted or if
the level of imported low-cost tubular goods were to otherwise increase, our
tubular services segment could be adversely



                                       8


affected to the extent that we then have higher-cost tubular goods in inventory.
If prices were to decrease significantly, we might not be able to profitably
sell our inventory of tubular goods. In addition, significant price decreases
could result in a longer holding period for some of our inventory, which could
also have a material adverse effect on our tubular services segment.

IF WE WERE TO LOSE A SIGNIFICANT SUPPLIER OF OUR TUBULAR GOODS, WE COULD BE
ADVERSELY AFFECTED.

         During 2001, we purchased from a single supplier approximately 40% of
the tubular goods we distributed and from three suppliers approximately 62% of
such tubular goods. We do not have contracts with any of these suppliers. If we
were to lose any of these suppliers or if production at one or more of the
suppliers were interrupted, our tubular services segment and our overall
business, financial condition and results of operations could be adversely
affected. If the extent of the loss or interruption were sufficiently large, the
impact on us would be material.

WE ARE SUBJECT TO EXTENSIVE AND COSTLY ENVIRONMENTAL LAWS AND REGULATIONS THAT
MAY REQUIRE US TO TAKE ACTIONS THAT WILL ADVERSELY AFFECT OUR RESULTS OF
OPERATIONS.

         Our hydraulic well control and drilling operations and our offshore
products business are significantly affected by stringent and complex foreign,
federal, state and local laws and regulations governing the discharge of
substances into the environment or otherwise relating to environmental
protection. We could be exposed to liability for cleanup costs, natural resource
damages and other damages as a result of our conduct that was lawful at the time
it occurred or the conduct of, or conditions caused by, prior operators or other
third parties. Environmental laws and regulations have changed in the past, and
they are likely to change in the future. If existing regulatory requirements or
enforcement policies change, we may be required to make significant
unanticipated capital and operating expenditures.

         Any failure by us to comply with applicable environmental laws and
regulations may result in governmental authorities taking actions against our
business that could adversely impact our operations and financial condition,
including the:

         o        issuance of administrative, civil and criminal penalties;

         o        denial or revocation of permits or other authorizations;

         o        reduction or cessation in operations; and

         o        performance of site investigatory, remedial or other
                  corrective actions.

WE MAY NOT HAVE ADEQUATE INSURANCE FOR POTENTIAL LIABILITIES.

         Our operations are subject to many hazards. We face the following risks
under our insurance coverage:

         o        we may not be able to continue to obtain insurance on
                  commercially reasonable terms;

         o        we may be faced with types of liabilities that will not be
                  covered by our insurance, such as damages from environmental
                  contamination;

         o        the dollar amount of any liabilities may exceed our policy
                  limits; and

         o        we do not maintain full coverage against the risk of
                  interruption of our business.

Even a partially uninsured claim, if successful and of significant size, could
have a material adverse effect on our results of operations or consolidated
financial position.




                                       9





WE ARE SUBJECT TO LITIGATION RISKS THAT MAY NOT BE COVERED BY INSURANCE.

         In the ordinary course of business, we become the subject of various
claims and litigation. We maintain insurance to cover many of our potential
losses, and we are subject to various self-retentions and deductibles under our
insurance. It is possible, however, that an unexpected judgment could be
rendered against us in cases in which we could be uninsured and beyond the
amounts that we currently have reserved or anticipate incurring for such
matters.

Risks Related to Oil States' Operations

WE HAVE INCURRED LOSSES IN THE PAST. WE MAY INCUR LOSSES IN THE FUTURE.

         We incurred a loss from continuing operations in 1999. We cannot assure
you that we will be profitable in the future.

LOSS OF KEY MEMBERS OF OUR MANAGEMENT COULD ADVERSELY AFFECT OUR BUSINESS.

         We depend on the continued employment and performance of Douglas E.
Swanson and other key members of management. If any of our key managers resign
or become unable to continue in their present roles and are not adequately
replaced, our business operations could be materially adversely affected. We do
not maintain any "key man" life insurance for any of our officers.

IF WE HAVE TO WRITE OFF A SIGNIFICANT AMOUNT OF GOODWILL, OUR EARNINGS WILL BE
NEGATIVELY AFFECTED.

         Our consolidated balance sheet as of December 31, 2001 included
goodwill representing 33% of our total assets. We have recorded goodwill because
we paid more for some of our businesses than the fair market value of the
tangible and separately measurable intangible net assets of those businesses.
Generally accepted accounting principles previously required us to amortize
goodwill over the periods we benefit from the acquired assets. Current
accounting standards, which were effective January 1, 2002 (See Note 3 to
Consolidated and Combined Financial Statements included in our Annual Report on
Form 10-K for the year ended December 31, 2001, which is incorporated by
reference herein), require a periodic review of goodwill for impairment in value
and a non-cash charge against earnings with a corresponding decrease in
stockholders' equity if circumstances indicate that the carrying amount will not
be recoverable.

WE MIGHT BE UNABLE TO PROTECT OUR INTELLECTUAL PROPERTY RIGHTS.

         We rely on a variety of intellectual property rights that we use in our
offshore products and well site services segments, particularly our patents
relating to our FlexJoint(TM) technology. We may not be able to successfully
preserve these intellectual property rights in the future and these rights could
be invalidated, circumvented or challenged. Technological developments may also
reduce the value of our intellectual property. In addition, the laws of some
foreign countries in which our products and services may be sold do not protect
intellectual property rights to the same extent as the laws of the United
States. The failure of our company to protect our proprietary information and
any successful intellectual property challenges or infringement proceedings
against us could adversely affect our competitive position.

BECAUSE WE ARE A NEWLY COMBINED COMPANY WITH A SHORT COMBINED OPERATING HISTORY,
NEITHER OUR HISTORICAL NOR OUR PRO FORMA FINANCIAL AND OPERATING DATA MAY BE
REPRESENTATIVE OF OUR FUTURE RESULTS.

         We are a newly combined company with a short period of combined
operating history. Our short combined operating history may make it difficult to
forecast our future operating results. The pro forma and combined financial
statements included in our Annual Report on Form 10-K for the year ended
December 31, 2001, which is incorporated by reference herein reflect the
separate historical results of operations, financial position and cash flows of
Oil States, Sooner, HWC and PTI prior to the Combination. The consolidated
financial statements reflect activity after the Combination.




                                       10


L.E. SIMMONS, THROUGH SCF, CONTROLS THE OUTCOME OF STOCKHOLDER VOTING AND MAY
EXERCISE THIS VOTING POWER IN A MANNER ADVERSE TO OUR STOCKHOLDERS.

         SCF holds approximately 63.2% of the outstanding common stock of our
company. L.E. Simmons, the chairman of our board of directors, is the sole owner
of L.E. Simmons & Associates, Incorporated, the ultimate general partner of SCF.
Accordingly, Mr. Simmons, through his ownership of the ultimate general partner
of SCF, is in a position to control the outcome of matters requiring a
stockholder vote, including the election of directors, adoption of amendments to
our certificate of incorporation or bylaws or approval of transactions involving
a change of control. The interests of Mr. Simmons may differ from those of our
stockholders, and SCF may vote its common stock in a manner that may adversely
affect our stockholders.

SCF'S OWNERSHIP INTEREST AND PROVISIONS CONTAINED IN OUR CERTIFICATE OF
INCORPORATION AND BYLAWS COULD DISCOURAGE A TAKEOVER ATTEMPT, WHICH MAY REDUCE
OR ELIMINATE THE LIKELIHOOD OF A CHANGE OF CONTROL TRANSACTION AND, THEREFORE,
THE ABILITY OF OUR STOCKHOLDERS TO SELL THEIR SHARES FOR A PREMIUM.

         In addition to SCF's controlling position, provisions contained in our
certificate of incorporation and bylaws, such as a classified board, limitations
on the removal of directors, on stockholder proposals at meetings of
stockholders and on stockholder action by written consent and the inability of
stockholders to call special meetings, could make it more difficult for a third
party to acquire control of our company. Our certificate of incorporation also
authorizes our board of directors to issue preferred stock without stockholder
approval. If our board of directors elects to issue preferred stock, it could
increase the difficulty for a third party to acquire us, which may reduce or
eliminate our stockholders' ability to sell their shares of common stock at a
premium. (See "Description of Capital Stock").

TWO OF OUR DIRECTORS MAY HAVE CONFLICTS OF INTEREST BECAUSE THEY ARE ALSO
DIRECTORS OR OFFICERS OF SCF. THE RESOLUTION OF THESE CONFLICTS OF INTEREST MAY
NOT BE IN OUR OR OUR STOCKHOLDERS' BEST INTERESTS.

         Two of our directors, L.E. Simmons and Andrew L. Waite, are also
current directors or officers of L.E. Simmons & Associates, Incorporated, the
ultimate general partner of SCF. This may create conflicts of interest because
these directors have responsibilities to SCF and its owners. Their duties as
directors or officers of L.E. Simmons & Associates, Incorporated may conflict
with their duties as directors of our company regarding business dealings
between SCF and us and other matters. The resolution of these conflicts may not
always be in our or our stockholders' best interest.

WE HAVE RENOUNCED ANY INTEREST IN SPECIFIED BUSINESS OPPORTUNITIES, AND SCF AND
ITS DIRECTOR NOMINEES ON OUR BOARD OF DIRECTORS GENERALLY HAVE NO OBLIGATION TO
OFFER US THOSE OPPORTUNITIES.

         SCF has investments in other oilfield service companies that compete
with us, and SCF and its affiliates, other than our company, may invest in other
such companies in the future. We refer to SCF, its other affiliates and its
portfolio companies as the SCF group. Our certificate of incorporation provides
that, so long as SCF and its affiliates continue to own at least 20% of our
common stock, we renounce any interest in specified business opportunities. Our
certificate of incorporation also provides that if an opportunity in the
oilfield services industry is presented to a person who is a member of the SCF
group, including any of those individuals who also serves as SCF's director
nominee of our company:

         o        no member of the SCF group or any of those individuals has any
                  obligation to communicate or offer the opportunity to us; and

         o        such entity or individual may pursue the opportunity as that
                  entity or individual sees fit,

unless:

         o        it was presented to an SCF director nominee solely in that
                  person's capacity as a director of our company and no other
                  member of the SCF group independently received notice of or
                  otherwise identified such opportunity; or



                                       11


         o        the opportunity was identified solely through the disclosure
                  of information by or on behalf of our company.

These provisions of our certificate of incorporation may be amended only by an
affirmative vote of holders of at least 80% of our outstanding common stock. As
a result of these charter provisions, our future competitive position and growth
potential could be adversely affected.

Risks Related to Ownership of Our Common Stock

THE AVAILABILITY OF SHARES OF OUR COMMON STOCK FOR FUTURE SALE COULD DEPRESS OUR
STOCK PRICE

         Sales by SCF and other stockholders of a substantial number of shares
of our common stock in the public markets, or the perception that such sales
might occur, could have a material adverse effect on the price of our common
stock or could impair our ability to obtain capital through an offering of
equity securities.

                                 USE OF PROCEEDS

         Because the shares of common stock will be issued in exchange for or
upon the redemption of the exchangeable shares, we will not receive any cash
proceeds upon the issuance of the common stock.

                          DESCRIPTION OF CAPITAL STOCK

         Our authorized capital stock consists of 200,000,000 shares of common
stock, par value $.01 per share, and 25,000,000 shares of preferred stock, par
value $.01 per share, of which one share has been designated as "special
preferred voting stock." At March 1, 2002, we had 48,332,207 shares of common
stock, including up to 3,601,329 shares of our common stock issuable upon
exchange of the exchangeable shares, and one share of special preferred voting
stock issued and outstanding.

COMMON STOCK

         Holders of common stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Because holders of common stock do
not have cumulative voting rights, the holders of a majority of the shares of
common stock can elect all of the members of the board of directors standing for
election, subject to the rights, powers and preferences of any outstanding
series of preferred stock. Subject to the rights and preferences of any
preferred stock that we may issue in the future, the holders of common stock are
entitled to receive:

         o        dividends as may be declared by our board of directors; and

         o        all of our assets available for distribution to our common
                  stockholders in liquidation, pro rata, based on the number of
                  shares held.

         There are no redemption or sinking fund provisions applicable to the
common stock. All outstanding shares of common stock are fully paid and
non-assessable. As of March 1, 2002, there were 77 holders of record of our
common stock.

PREFERRED STOCK

         Subject to the provisions of our certificate of incorporation and legal
limitations, our board of directors has the authority, without further vote or
action by the stockholders:

         o        to issue up to 25,000,000 shares of preferred stock in one or
                  more series; and

         o        to fix the rights, preferences, privileges and restrictions of
                  our preferred stock, including provisions related to
                  dividends, conversion, voting, redemption, liquidation and the
                  number of shares constituting the series or the designation of
                  that series, which may be superior to those of the common
                  stock.



                                       12


Other than the share of special preferred voting stock issued in connection with
the Combination as described below in "Special Preferred Voting Stock," as of
March 1, 2002, there are no shares of preferred stock outstanding, and we have
no present plans to issue any other preferred stock.

         The issuance of shares of preferred stock by our board of directors as
described above may adversely affect the rights of the holders of our common
stock. For example, preferred stock may rank prior to the common stock as to
dividend rights, liquidation preference or both, may have full or limited voting
rights and may be convertible into shares of common stock. The issuance of
shares of preferred stock may discourage third-party bids for our common stock
or may otherwise adversely affect the market price of the common stock. In
addition, the preferred stock may enable our board of directors to make more
difficult or to discourage attempts to obtain control of our company through a
hostile tender offer, proxy contest, merger or otherwise, or to make changes in
our management.

EXCHANGEABLE SHARES

         In the Combination, the outstanding common shares of PTI held by
Canadian residents were exchanged for exchangeable shares issued by PTI HoldCo.
The exchangeable shares may generally be exchanged at any time after the first
anniversary of the closing of the Combination at the option of the holders for
our common stock on a share-for-share basis subject to adjustment in the case of
alterations to our common stock, plus the amount of any declared but unpaid
dividends on our common stock. As of March 1, 2002, there are 3,601,329
exchangeable shares outstanding, which are exchangeable for a total of 3,601,329
shares of our common stock. The following is a summary of the principal terms
and rights of the exchangeable shares which affect us and the holders of our
common stock.

         Holders of exchangeable shares are entitled to:

         o        receive dividends equal to the dividends paid by us on shares
                  of our common stock;

         o        provide directions to the holder of our special preferred
                  voting stock as to the manner in which the special preferred
                  voting stock should be voted on any matter on which holders of
                  our common stock are entitled to vote. See "-- Special
                  Preferred Voting Stock" below.

Subject to applicable law, exchangeable shares will be exchanged for shares of
our common stock on a share-for-share basis, plus an amount equal to all
declared and unpaid dividends on such exchangeable shares, whenever:

         o        the holders of exchangeable shares request us or PTI HoldCo to
                  exchange or redeem their exchangeable shares;

         o        PTI HoldCo is liquidated, dissolved or wound-up;

         o        PTI HoldCo becomes insolvent or bankrupt, has a receiver
                  appointed or a similar event occurs;

         o        we become involved in voluntary or involuntary liquidation,
                  dissolution or winding-up proceedings;

         o        PTI HoldCo elects to redeem all of the exchangeable shares,
                  provided the request is made after the fifth anniversary of
                  the closing of the offering;

         o        PTI HoldCo elects to redeem all of the exchangeable shares,
                  provided the request is made after either the third
                  anniversary of the closing of the offering and the number of
                  outstanding exchangeable shares is less than 10% of the number
                  outstanding upon the closing of the Combination or the fourth
                  anniversary of the closing of the offering and the number of
                  outstanding exchangeable shares is less than 20% of the number
                  outstanding upon the closing of the Combination;

         o        a change of control transaction occurs and the board of
                  directors of PTI HoldCo determines in good faith and in its
                  sole discretion that it is not reasonable to substantially
                  replicate the terms and conditions of the exchangeable shares
                  in connection with the change of control transaction and that



                                       13


                  redemption of all of the outstanding exchangeable shares is
                  commercially or legally necessary to enable the completion of
                  the change of control transaction;

         o        the holders of exchangeable shares fail to pass a resolution
                  regarding any matter on which they are entitled to vote as
                  shareholders of PTI HoldCo and which has been proposed by the
                  board of directors of PTI HoldCo, other than any resolution to
                  amend the exchangeable share provisions, the support agreement
                  or the voting and exchange trust agreement; or

         o        the holders of the exchangeable shares fail to take any action
                  required to approve or disapprove any change to their rights
                  if the approval or disapproval of such change would be
                  required to maintain the economic or legal equivalence of the
                  exchangeable shares and our common stock.

Whenever a holder of exchangeable shares has the right to require PTI HoldCo to
redeem the holder's exchangeable shares or whenever PTI HoldCo has the right or
is required to redeem the outstanding exchangeable shares, the exchangeable
shares to be redeemed will be subject to the overriding right of our company or
3045843 Nova Scotia Company, one of our wholly owned Canadian subsidiaries, to
purchase such exchangeable shares. The consideration to be paid by us or 3045843
Nova Scotia Company, as the case may be, will be identical to the consideration
to be paid by PTI HoldCo upon any such redemption. We expect to exercise the
overriding right to purchase the exchangeable shares whenever it arises.

         Unless we take action to ensure that the holders of exchangeable shares
receive an equivalent economic benefit, and subject to applicable law, we may
not:

         o        issue or distribute assets, debt instruments or shares of, or
                  securities convertible into, our common stock to the holders
                  of the then outstanding shares of our common stock;

         o        effect a forward or reverse stock split or similar
                  transaction;

         o        effect a merger, reorganization, consolidation or other
                  transaction involving or affecting our common stock; or

         o        reclassify or otherwise change our common stock.

         In the event of any proposed tender offer, share exchange offer, issuer
bid, take-over bid or similar transaction affecting our common stock, we must
use reasonable efforts to take all actions necessary or desirable to enable
holders of exchangeable shares to participate in the transaction to the same
extent and on an economically equivalent basis as the holders of our common
stock. We have also agreed to take various actions to protect the rights of the
holders of the exchangeable shares to receive the same dividends as are paid on
our common stock and to exchange shares of our common stock for exchangeable
shares.

SPECIAL PREFERRED VOTING STOCK

         In connection with the acquisition of PTI, our board of directors
authorized a class of preferred stock, referred to as "special preferred voting
stock," consisting of one share. The special preferred voting stock was issued
to Computershare Trust Company of Canada, which holds the share as trustee for
the benefit of the holders of the exchangeable shares described above. Except as
otherwise required by law or our certificate of incorporation:

         o        the special preferred voting stock is entitled to the number
                  of votes attached to the number of shares of our common stock
                  issuable upon the exchange of all the outstanding exchangeable
                  shares;

         o        each holder of exchangeable shares is able to direct the
                  trustee to vote that number of votes that are attached to the
                  number of shares of OSI common stock issuable upon the
                  exchange of the exchangeable shares held by that holder;



                                       14


         o        the special preferred voting stock may be voted in the
                  election of directors and on all other matters submitted to a
                  vote of our common stockholders; and

         o        the holder of the special preferred voting stock is not
                  entitled to receive dividends.

         In the event of any liquidation, dissolution or winding up of our
company, the holder of the special preferred voting stock will not be entitled
to any of our assets available for distribution to stockholders. We may redeem
the special preferred voting stock for a nominal amount when:

         o        the special preferred voting stock has no votes attached to it
                  because there are no exchangeable shares outstanding that are
                  not owned by us or our subsidiaries; and

         o        there are no shares of stock, debt, options or other
                  agreements that could give rise to the issuance of any
                  additional exchangeable shares to any person other than us or
                  any of our subsidiaries.

ANTI-TAKEOVER PROVISIONS OF OUR CERTIFICATE OF INCORPORATION AND BYLAWS

         Our certificate of incorporation and bylaws contain several provisions
that could delay or make more difficult the acquisition of us through a hostile
tender offer, open market purchases, proxy contest, merger or other takeover
attempt that a stockholder might consider in his or her best interest, including
those attempts that might result in a premium over the market price of our
common stock.

Written Consent of Stockholders

         Our certificate of incorporation provides that, on and after the date
when SCF ceases to own a majority of the shares of our outstanding securities
entitled to vote in the election of directors, any action by our stockholders
must be taken at an annual or special meeting of stockholders, and stockholders
cannot act by written consent. Until that date, any action required or permitted
to be taken by our stockholders may be taken at a duly called meeting of
stockholders or by the written consent of stockholders owning the minimum number
of shares required to approve the action.

Special Meetings of Stockholders

         Subject to the rights of the holders of any series of preferred stock,
our bylaws provide that special meetings of the stockholders may only be called
by the chairman of the board of directors or by the resolution of a majority of
our board of directors.

Advance Notice Procedure for Director Nominations and Stockholder Proposals

         Our bylaws provide that adequate notice must be given to nominate
candidates for election as directors or to make proposals for consideration at
annual meetings of stockholders. Notice of a stockholder's intent to nominate a
director must be delivered to or mailed and received at our principal executive
offices as follows:

         o        for an election to be held at the annual meeting of
                  stockholders, not later than 120 calendar days prior to the
                  anniversary date of the immediately preceding annual meeting
                  of stockholders unless the date of the annual meeting is more
                  than 30 or less than 60 calendar days after such anniversary
                  date, in which case such notice must be received not later
                  than the later of (1) 120 calendar days prior to the annual
                  meeting or (2) 10 calendar days following the public
                  announcement of the annual meeting; and

         o        for an election to be held at a special meeting of
                  stockholders, not later than the later of (1) 120 calendar
                  days prior to the special meeting or (2) 10 calendar days
                  following the public announcement of the special meeting.



                                       15


         Notice of a stockholder's intent to raise business at an annual meeting
must be received at our principal executive offices not later than 120 calendar
days prior to the anniversary date of the preceding annual meeting of
stockholders.

         These procedures may operate to limit the ability of stockholders to
bring business before a stockholders meeting, including the nomination of
directors and the consideration of any transaction that could result in a change
in control and that may result in a premium to our stockholders.

CLASSIFIED BOARD OF DIRECTORS

         Our certificate of incorporation divides our directors into three
classes serving staggered three-year terms. As a result, stockholders will elect
approximately one-third of the board of directors each year. This provision,
when coupled with the provision of our restated certificate of incorporation
authorizing only the board of directors to fill vacant or newly created
directorships or increase the size of the board of directors and the provision
providing that directors may only be removed for cause, may deter a stockholder
from gaining control of our board of directors by removing incumbent directors
or increasing the number of directorships and simultaneously filling the
vacancies or newly created directorships with its own nominees.

RENOUNCEMENT OF BUSINESS OPPORTUNITIES

         Our certificate of incorporation provides that, as long as SCF and its
affiliates other than our company continue to own at least 20% of our common
stock, we renounce any interest or expectancy in any business opportunity or
other matter in which any member of the SCF group participates or desires or
seeks to participate and that involves any aspect of the energy equipment or
services business or industry except as described below. No member of the SCF
group, including any officer, director, employee or other agent of SCF or any
affiliate of SCF who serves as a director of our company (an "SCF director
nominee"), has any obligation to communicate or offer any renounced opportunity
to us and may pursue the opportunity as that entity or individual sees fit,
unless:

         o        it was presented to an SCF director nominee solely in that
                  person's capacity as a director of our company and no other
                  member of the SCF group independently received notice of or
                  otherwise identified such opportunity; or

         o        the opportunity was identified solely through the disclosure
                  of information by or on behalf of our company.

The "SCF group" includes SCF, any affiliate of SCF (other than our company), any
SCF director nominee and portfolio companies in which SCF has an investment
(other than our company).

         Thus, for example, SCF and its affiliates, including SCF director
nominees, may pursue opportunities in the oilfield services industry for their
own account or present such opportunities to SCF's other portfolio companies.
Our certificate of incorporation provides that SCF and its affiliates have no
obligation to offer such opportunities to us, even if the failure to provide
such opportunity would have a competitive impact on us.

         These provisions of our certificate of incorporation may be amended
only by an affirmative vote of holders of at least 80% of our outstanding common
stock.

AMENDMENT OF THE BYLAWS

         Our board of directors may amend or repeal the bylaws and adopt new
bylaws. The holders of common stock may amend or repeal the bylaws and adopt new
bylaws by a majority vote.

LIMITATION OF LIABILITY OF OFFICERS AND DIRECTORS

         Our directors will not be personally liable to our company or our
stockholders for monetary damages for breach of fiduciary duty as a director,
except, if required by Delaware law, for liability:



                                       16


         o        for any breach of the duty of loyalty to our company or our
                  stockholders;

         o        for acts or omissions not in good faith or involving
                  intentional misconduct or a knowing violation of law;

         o        for unlawful payment of a dividend or unlawful stock purchases
                  or redemptions; and

         o        for any transaction from which the director derived an
                  improper personal benefit.

As a result, neither we nor our stockholders have the right, through
stockholders' derivative suits on our behalf, to recover monetary damages
against a director for breach of fiduciary duty as a director, including
breaches resulting from grossly negligent behavior, except in the situations
described above.

DELAWARE TAKEOVER STATUTE

         Under the terms of our certificate of incorporation and as permitted
under Delaware law, we have elected not to be subject to Delaware's
anti-takeover law in order to give our significant stockholders, including SCF,
greater flexibility in transferring their shares of our common stock. This law
provides that specified persons who, together with affiliates and associates,
own, or within three years did own, 15% or more of the outstanding voting stock
of a corporation could not engage in specified business combinations with the
corporation for a period of three years after the date on which the person
became an interested stockholder. The law defines the term "business
combination" to encompass a wide variety of transactions with or caused by an
interested stockholder, including mergers, asset sales and other transactions in
which the interested stockholder receives or could receive a benefit on other
than a pro rata basis with other stockholders. With the approval of our
stockholders, we may amend our certificate of incorporation in the future to
become governed by the anti-takeover law. This provision would then have an
anti-takeover effect for transactions not approved in advance by our board of
directors, including discouraging takeover attempts that might result in a
premium over the market price for the shares of our common stock. By opting out
of the Delaware anti-takeover law, a transferee of SCF could pursue a takeover
transaction that was not approved by our board of directors.

TRANSFER AGENT AND REGISTRAR

         The transfer agent and registrar for our common stock is Mellon
Investor Services LLC, and its telephone number is (800) 635-9270.

                              PLAN OF DISTRIBUTION

         We will distribute up to 3,601,329 shares of common stock covered by
this prospectus only upon exchange or redemption of the exchangeable shares of
PTI HoldCo. No broker, dealer or underwriter has been engaged in connection with
the exchange or redemption. Each exchangeable share of PTI HoldCo may be
exchanged or redeemed for one share of common stock. We will pay any other
expenses incurred in connection with the distribution described in this
prospectus.

                            INCOME TAX CONSIDERATIONS

CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

         In the opinion of Donahue LLP, our Canadian counsel, the following is
an accurate summary of the principal Canadian federal income tax considerations
under the Canadian Income Tax Act generally applicable to you if you hold
exchangeable shares or acquire common stock on the redemption, retraction or
exchange of exchangeable shares and if, for purposes of the Income Tax Act
(Canada) (the "Tax Act") and any applicable income tax treaty or convention, you
are or are deemed to be resident in Canada at all relevant times, you deal with
us at arm's length, you are not affiliated with us and you hold your
exchangeable shares and will hold the common stock as capital property. This
discussion does not apply to you if you are a "financial institution," as
defined in the



                                       17


Tax Act, and are therefore subject to the mark-to-market rules of the Tax Act.
This summary also does not apply to you if Oil States is or will be a "foreign
affiliate" of you for purposes of the Tax Act.

         The exchangeable shares and common stock will generally be considered
to be capital property to you unless the shares are held by you in the course of
carrying on a business or the shares are acquired in a transaction considered to
be an adventure in the nature of trade. If the exchangeable shares might not
otherwise qualify as capital property, you may be entitled to obtain this
qualification by making the irrevocable election provided under subsection 39(4)
of the Tax Act. If you do not hold your exchangeable shares or will not hold
common stock as capital property, you should consult your own tax advisors for
information and advice having regard to your particular circumstances.

         This summary is based on the current provisions of the Tax Act and the
regulations thereto, the current provisions of the Convention Between the United
States of America and Canada with Respect to Taxes on Income and on Capital,
signed September 26, 1980, as amended, and our Canadian counsel's understanding
of the current published administrative practices of the Canada Customs and
Revenue Agency (the "CCRA"). This summary takes into account all specific
proposals to amend the Tax Act and regulations that have been publicly announced
by or on behalf of the Minister of Finance (Canada) prior to the date hereof and
assumes that all of these proposed amendments will be enacted in their present
form. No assurances can be given that any proposed amendments will be enacted in
the form proposed, or at all. This summary is not exhaustive of all possible
Canadian federal income tax considerations and, except for the foregoing, does
not take into account or anticipate any changes in law, whether by legislative,
administrative or judicial decision or action, nor does it take into account
provincial, territorial or foreign income tax legislation or considerations,
which may differ from the Canadian federal income tax considerations described
below. No advance income tax ruling has been sought or obtained from the CCRA to
confirm the tax consequences of any of the transactions relating to the
exchangeable shares or the acquisition of the common stock on the redemption,
retraction or exchange of exchangeable shares.

         For purposes of the Tax Act, all amounts relating to the acquisition,
holding or disposition of common stock, including dividends, adjusted cost base
amounts and proceeds of disposition, must be converted into Canadian dollars
based on the prevailing United States dollar exchange rate generally at the time
these amounts arise.

         THIS SUMMARY IS OF A GENERAL NATURE ONLY AND IS NOT INTENDED TO BE, AND
SHOULD NOT BE CONSTRUED TO BE, LEGAL, BUSINESS OR TAX ADVICE TO YOU. THEREFORE,
YOU SHOULD CONSULT YOUR OWN TAX ADVISORS WITH RESPECT TO YOUR PARTICULAR
CIRCUMSTANCES.

Redemption or Exchange of Exchangeable Shares

         On a redemption (including a retraction) of your exchangeable shares by
PTI HoldCo, you will be deemed to have received a dividend equal to the amount,
if any, by which the redemption proceeds exceed the paid-up capital (for
purposes of the Tax Act) of the exchangeable shares so redeemed. For these
purposes, the redemption proceeds will be the fair market value of the common
stock received from PTI HoldCo on the redemption plus the amount, if any, of all
payable and unpaid dividends on the exchangeable shares paid on the redemption.
The amount of any such deemed dividend will be subject to the tax treatment
described below under "Dividends on Exchangeable Shares."

         On a redemption (including a retraction) of your exchangeable shares,
you will also be considered to have disposed of your exchangeable shares, but
the amount of the deemed dividend will be excluded in computing your proceeds of
disposition for purposes of computing any capital gain or capital loss arising
on the disposition. If you are a corporation, in some circumstances the amount
of any such deemed dividend may be treated as proceeds of disposition and not as
a dividend. The taxation of capital gains and capital losses is described below.

         On an exchange of your exchangeable shares with our indirect
wholly-owned subsidiary, 3045843 Nova Scotia Company (hereinafter referred to as
"OSI ULC"), or with us for the common stock, you will generally realize a
capital gain (or a capital loss) equal to the amount by which the proceeds of
disposition of your exchangeable shares, net of any reasonable costs of
disposition, exceed (or are less than) the adjusted cost base to you of the
exchangeable shares immediately before the exchange. For these purposes, the
proceeds of disposition will be the fair market value at the time of the
exchange of the common stock which you receive plus any other amounts



                                       18


received from us as part of the exchange, other than any amount paid in
satisfaction of declared and unpaid dividends owed to you by PTI HoldCo. The
taxation of capital gains and capital losses is described below.

         BECAUSE OF THE EXISTENCE OF CERTAIN CALL RIGHTS HELD BY OSI ULC WHICH
GIVE OSI ULC THE OVERRIDING RIGHT TO PURCHASE YOUR EXCHANGEABLE SHARES UPON A
REDEMPTION (INCLUDING A RETRACTION) BY EXCHANGING A SHARE OF COMMON STOCK FOR
EACH EXCHANGEABLE SHARE AS WELL AS CERTAIN RIGHTS OF HOLDERS OF EXCHANGEABLE
SHARES TO FORCE THE EXCHANGE OF EXCHANGEABLE SHARES WITH OIL STATES FOR COMMON
STOCK UPON THE OCCURRENCE OF THE LIQUIDATION, DISSOLUTION OR WINDING-UP OF PTI
HOLDCO OR OIL STATES, YOU CANNOT CONTROL WHETHER YOU WILL RECEIVE COMMON STOCK
BY WAY OF A REDEMPTION (INCLUDING A RETRACTION) OF YOUR EXCHANGEABLE SHARES BY
PTI HOLDCO OR BY WAY OF PURCHASE OF THE EXCHANGEABLE SHARES BY OIL STATES OR OSI
ULC. AS DESCRIBED ABOVE, THE CANADIAN FEDERAL INCOME TAX CONSEQUENCES OF A
REDEMPTION (INCLUDING A RETRACTION) DIFFER FROM THOSE OF A PURCHASE.

Disposition of Exchangeable Shares Other Than on Redemption or Exchange

         A disposition or deemed disposition of your exchangeable shares, other
than on the redemption or exchange of your exchangeable shares, will generally
result in a capital gain (or capital loss) to the extent that the proceeds of
disposition, net of any reasonable costs of disposition, exceed (or are less
than) the adjusted cost base to you immediately before the disposition. The
taxation of capital gains and capital losses is described below.

Acquisition and Disposition of the Common Stock

         The cost of the common stock received on a retraction, redemption or
exchange of exchangeable shares will be equal to the fair market value of the
common stock at the time of that event, and will be averaged with the adjusted
cost base of any other shares of common stock held by you at that time as
capital property (other than common stock considered to have been continually
held by you since 1971) for the purpose of determining the adjusted cost base of
your common stock.

         A disposition or deemed disposition of the common stock by you will
generally result in a capital gain (or a capital loss) equal to the amount by
which the proceeds of disposition, net of any reasonable costs of disposition,
exceed (or are less than) the adjusted cost base to you of such shares
immediately before the disposition. The taxation of capital gains and capital
losses is described below.

Dividends on Exchangeable Shares

         If you are an individual, dividends received or deemed to be received
on the exchangeable shares will be included in computing your income, and will
be subject to the gross-up and dividend tax credit rules normally applicable to
taxable dividends received from a corporation resident in Canada. Subject to the
discussion below, if you are a corporation, other than a "specified financial
institution" as defined in the Tax Act, dividends received or deemed to be
received on the exchangeable shares normally will be included in your income and
deductible in computing your taxable income.

         The exchangeable shares will be "term preferred shares," as defined in
the Tax Act. Consequently, if you are a "specified financial institution," as
defined in the Tax Act, a dividend received or deemed to be received on a
redemption of the exchangeable shares will be deductible in computing your
taxable income only if:

         o        you did not acquire the exchangeable shares in the ordinary
                  course of carrying on your business; or

         o        at the time the dividend is received, the exchangeable shares
                  are listed on a prescribed stock exchange in Canada (which
                  currently includes the Toronto Stock Exchange (TSE)) and you,
                  either alone or together with persons with whom you do not
                  deal at arm's length, do not receive (or are not deemed to
                  receive) dividends in respect of more than 10% of the issued
                  and outstanding exchangeable shares.




                                       19


         If you are a "private corporation," as defined in the Tax Act, or any
other corporation resident in Canada and controlled or deemed to be controlled
by or for the benefit of an individual or a related group of individuals, you
may be liable under Part IV of the Tax Act to pay a refundable tax of 331/3% of
any dividends received or deemed to be received on your exchangeable shares to
the extent that these dividends are deductible in computing your taxable income.

         If you are throughout the relevant taxation year a "Canadian-controlled
private corporation," as defined in the Tax Act, you may be liable to pay an
additional refundable tax of 6 2/3% on dividends received or deemed to be
received on your exchangeable shares that are not deductible in computing
taxable income.

Dividends on the Common Stock

         Dividends on the common stock will be included in your income for the
purposes of the Canadian Income Tax Act. If you are an individual, you will not
be subject to the gross-up and dividend tax credit rules in the Canadian Income
Tax Act applicable to dividends received from corporations resident in Canada.
If you are a corporation, you will be required to include these dividends in
computing your income and generally will not be entitled to deduct the amount of
these dividends in computing your taxable income. If you are throughout the
relevant taxation year a "Canadian-controlled private corporation," as defined
in the Tax Act, you may be liable to pay an additional refundable tax of 62/3%
on such dividends. If there is United States non-resident withholding tax on any
dividends you receive on the common stock, you will generally be eligible for
foreign tax credit or deduction treatment where applicable under the Tax Act.

Taxation of Capital Gains and Capital Losses

         One-half of any capital gain (a "taxable capital gain") realized by you
on a disposition or deemed disposition of exchangeable shares or the common
stock must be included in your income for the year of the disposition. One-half
of any capital loss (an "allowable capital loss") realized by you may be
deducted by you against taxable capital gains realized in the year of the
disposition. Any allowable capital losses in excess of taxable capital gains in
the year of disposition may be carried back up to three taxation years or
forward indefinitely and deducted against net taxable capital gains in those
other years to the extent and in the circumstances prescribed in the Tax Act.

         Capital gains realized by an individual or trust, other than certain
trusts, may give rise to alternative minimum tax under the Tax Act.

         If you are throughout the relevant taxation year a "Canadian-controlled
private corporation," as defined in the Tax Act, you may be liable to pay an
additional refundable tax of 6 2/3% on taxable capital gains.

         If you are a corporation, the amount of any capital losses arising from
a disposition or deemed disposition of exchangeable shares may be reduced by the
amount of any dividends received or deemed to have been received by you on the
exchangeable shares to the extent and under circumstances prescribed by the Tax
Act. Similar rules may apply where you are a corporation that is a member of a
partnership or a beneficiary of a trust that owns exchangeable shares or common
shares or where a trust or partnership of which a corporation is a beneficiary
or a member owns any of these shares. You should consult your own tax advisors
if these rules may be relevant to you.




                                       20





Foreign Property Information Reporting

         If you are a "specified Canadian entity" (as defined in the Tax Act),
you may be required to file an information return relating to any "specified
foreign property" (as defined in the Tax Act) owned by you, which would include
the common stock, the exchangeable shares and certain exchange and voting rights
relating thereto. You should consult you own advisors about whether you must
comply with these rules with respect to the ownership of exchangeable shares or
common stock.

Foreign Investment Entity Draft Legislation

         Draft legislation regarding the taxation of investments in "foreign
investment entities" was released on August 2, 2001. In general, if the draft
legislation applies, a holder of an interest in a foreign investment entity
generally will be required to take into account in computing income changes in
the value of that interest. A corporation is not a foreign investment entity if
the "carrying value" of all of its "investment property" is not greater than
one-half of the "carrying value" of all of its property or if its principal
business is not an "investment business" within the meaning of those terms in
the draft legislation. We believe that we would not currently be a "foreign
investment entity" under the draft legislation; however, no assurances can be
given that the draft legislation will be enacted in its current form. On
December 17, 2001, the Department of Finance (Canada) issued a press release
announcing that the effective date for the proposed rules will be delayed one
year, generally to take effect for taxation years commencing after 2002, to
allow time for consultation on the draft legislation.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

         In the opinion of Vinson & Elkins L.L.P., our United States counsel,
the following is an accurate summary of the principal United States federal
income tax considerations under the United States Internal Revenue Code of 1986,
as amended (the "Code"), generally applicable to you if you are a holder of
exchangeable shares and you are not:

         o        a citizen or resident of the United States;

         o        a corporation or other entity taxable as a corporation created
                  or organized in or under the laws of the United States or of
                  any political subdivision thereof;

         o        an estate, the income of which is subject to United States
                  federal income taxation regardless of its source; or

         o        a trust if a United States court is able to exercise primary
                  supervision over the administration of the trust and one or
                  more United States persons have the authority to control all
                  substantial decisions of the trust.

         This summary does not discuss all United States federal income tax
considerations that may be relevant to you in light of your particular
circumstances or if you are subject to special treatment under the Code. This
summary is applicable to you only if you hold exchangeable shares as capital
assets and does not consider your tax treatment if you hold exchangeable shares
through a partnership or other pass-through entity. Furthermore, this summary
does not discuss any aspects of foreign, state or local taxation. This summary
is based on current provisions of the Code, existing, temporary and proposed
regulations promulgated under the Code and administrative and judicial
interpretations of the Code, all of which are subject to change, possibly with
retroactive effect. No advance income tax ruling has been sought or obtained
from the Internal Revenue Service (the "IRS") regarding the tax consequences of
the transactions described herein.




                                       21





         YOU ARE ADVISED TO CONSULT YOUR TAX ADVISORS WITH RESPECT TO THE UNITED
STATES FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE TRANSACTIONS
DESCRIBED HEREIN.

Sale or Exchange of Exchangeable Shares

         You generally will not be subject to United States federal income tax
on any gain realized on the sale or exchange of exchangeable shares, including
the exchange of exchangeable shares for common stock, unless the gain is
effectively connected with your United States trade or business or, if you are
an individual, you are present in the United States for 183 days or more during
the taxable year of disposition and certain other conditions are satisfied.

Dividends on the Common Stock

         Dividends paid to you as a holder of common stock generally will be
subject to withholding of United States federal income tax at a rate of 30% (or
such lower rate as may be specified by an applicable income tax treaty) unless
the dividend is effectively connected with the conduct of your trade or business
within the United States (or if a tax treaty applies, is attributable to your
United States permanent establishment), in which case the dividend will be taxed
at ordinary United States federal income tax rates. If you are a corporation,
such effectively connected income may also be subject to an additional "branch
profits tax." You will be required to satisfy certain certification requirements
to claim treaty benefits or otherwise claim a reduction of, or exemption from,
the withholding tax described above.

Sale or Exchange of Common Stock

         You generally will not be subject to United States federal income tax
on any gain realized on the sale or exchange of shares of common stock unless:

         o        the gain is effectively connected with your United States
                  trade or business; or

         o        you are an individual and you are present in the United States
                  for 183 days or more during the taxable year of disposition
                  and certain other conditions are satisfied.

Backup Withholding and Information Reporting

         You are generally subject to information reporting requirements with
respect to dividends paid by us to you and any tax withheld with respect to such
dividends. Copies of the information returns reporting such dividends and
withholding may also be made available to the tax authorities in the country in
which you reside under the provisions of an applicable income tax treaty. You
will be subject to backup withholding unless applicable certification
requirements are met. Payment of the proceeds of a sale of shares of the common
stock within the United States or through certain United States brokers is
subject to both backup withholding and information reporting unless you as
beneficial owner certify under penalties of perjury that you are not a United
States person for purposes of the Code (and the payor does not have actual
knowledge or reason to know that you are a United States person) or otherwise
establishes an exemption.

         Backup withholding tax is not a separate tax. Any amounts withheld
under the backup withholding rules are generally allowable as a credit against
your United States federal income tax liability (if any), which may entitle you
to a refund, provided that the required information is furnished to the IRS.

         The discussion of United States federal income tax consequences set
forth above is for general information only and does not purport to be a
complete analysis or listing of all potential tax effects that may apply to you.
You are strongly encouraged to consult your tax adviser to determine the
particular tax consequences to you, including the application and effect of
United States federal, state, local and foreign tax laws.

              TOTAL..................................................      $ 27,064
                                                                           ========


         The foregoing does not include New York Stock Exchange listing fees
that were paid in connection with the Company's initial public offering in
February 2001.

Item 15. Indemnification of Directors and Officers.

         Section 145 of the Delaware General Corporation Law ("DGCL") provides
that a corporation may indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding whether civil, criminal, administrative or investigative,
other than an action by or in the right of the corporation by reason of the fact
that he is or was a director, officer, employee or agent of the corporation, or
is or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, against expenses, including attorney's fees, judgments, fines
and amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit or proceeding if he acted in good faith and in
a manner he reasonably believed to be in or not opposed to the best interests of
the corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. Section 145 further
provides that a corporation similarly may indemnify any such person serving in
any such capacity who was or is a party or is threatened to be made a party to
any threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he is
or was a director, officer, employee or agent of the corporation or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses, including attorneys' fees, actually and reasonably
incurred in connection with the defense or settlement of such action or suit if
he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Delaware Court of Chancery or such other
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of liability but in view of all of the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the Delaware Court of Chancery or such other
court shall deem proper.

         The Company's certificate of incorporation provides that
indemnification shall be to the fullest extent permitted by the DGCL for all
current or former directors or officers of the Company.

         As permitted by the DGCL, the certificate of incorporation provides
that directors of the Company shall have no personal liability to the Company or
its stockholders for monetary damages for breach of fiduciary duty as a
director, except (1) for any breach of the director's duty of loyalty to the
Company or its stockholders, (2) for acts or omissions not in good faith or
which involve intentional misconduct or knowing violation of law, (3) under
Section 174 of the DGCL or (4) for any transaction from which a director derived
an improper personal benefit.

         In addition, we have entered into indemnity agreements with our
directors and executive officers containing provisions which are in some
respects broader than the specific indemnification provisions contained in the
DGCL.


                                      II-1


The form of these indemnity agreements is filed as Exhibit 10.14 to Amendment
No. 4 to the Company's Registration Statement on Form S-1 (File No. 333-43400)
filed with the SEC on January 19, 2001.

         The U.S. and international purchase agreements that we entered into in
connection with our initial public offering contain certain provisions for the
indemnification against certain civil liabilities under the Securities Act of
our directors, certain of our officers, the selling stockholders and any person
who controls us within the meaning of Section 15 of the Securities Act or
Section 20 of the Securities and Exchange Act of 1934. Forms of these purchase
agreements are filed as Exhibits 1.1 and 1.2 to Amendment No. 5 to the Company's
Registration Statement on Form S-1 (File No. 333-43400) filed with the SEC on
February 6, 2001.

Item 17. Undertakings.

         The undersigned registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made
         of the securities registered hereby, a post-effective amendment to this
         registration statement:

                  (i) To include any prospectus required by Section 10(a)(3) of
                  the Securities Act;

                  (ii) To reflect in the prospectus any facts or events arising
                  after the effective date of the registration statement (or the
                  most recent post-effective amendment thereof) which,
                  individually or in the aggregate, represent a fundamental
                  change in the information set forth in the registration
                  statement. Notwithstanding the foregoing, any increase or
                  decrease in volume of securities offered (if the total dollar
                  value of securities offered would not exceed that which was
                  registered) and any deviation from the low or high end of the
                  estimated maximum offering range may be reflected in the form
                  of prospectus filed with the Commission pursuant to Rule
                  424(b) if, in the aggregate, the changes in volume and price
                  represent no more than a 20 percent change in the maximum
                  aggregate offering price set forth in the "Calculation of
                  Registration Fee" table in the effective registration
                  statement;

                  (iii) To include any material information with respect to the
                  plan of distribution not previously disclosed in the
                  registration statement or any material change to such
                  information in the registration statement;

         (2) That, for the purpose of determining any liability under the
         Securities Act, 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; and

         (3) To remove from registration by means of a post-effective amendment
         any of the securities being registered which remain unsold at the
         termination of the offering.

         The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of Oil States
International Inc.'s annual report pursuant to Section 13(a) or Section 15(d) of
the Exchange Act that is incorporated by reference in the registration statement
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.

         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 indemnification provisions described in Item 15
above, 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.
