                         PROSPECTUS SUPPLEMENT SUMMARY

     This summary highlights selected information from this prospectus
supplement and the accompanying prospectus, but does not contain all information
that may be important to you. This prospectus supplement and the accompanying
prospectus include specific terms of this offering, information about our
business and financial data. We encourage you to read this prospectus supplement
and the accompanying prospectus, including the documents incorporated by
reference, in their entirety before making an investment decision. Unless
otherwise indicated, this prospectus supplement assumes no exercise of the
underwriters' over-allotment option. Unless otherwise indicated, or the context
otherwise requires, references to "Oil States," "we," "us" and "our" or similar
terms are to Oil States International, Inc. and its subsidiaries.

OUR COMPANY

     We are a leading provider of specialty products and services to oil and gas
drilling and production companies throughout the world. We operate in a
substantial number of the world's most active oil and gas producing regions,
including the Gulf of Mexico, U.S. onshore, 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 believe that our operating and financial performance has been strong
since our initial public offering in February 2001 due to:

     - our leadership position in various product and service niches;

     - improving fundamentals in deepwater oil and gas development activities
       and North American natural gas development and production activities;

     - our diversity of operations, which helps us mitigate the earnings and
       cash flow volatility within each of our segments; and

     - proactive measures we have taken to make our operations more efficient.

     We operate in three principal business segments: offshore products, well
site services and tubular services.

  OFFSHORE PRODUCTS

     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.
In addition, this segment provides onshore oil and gas, defense and general
industrial products and services.

     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 for the drilling and production of oil and gas
wells on offshore fixed platforms and mobile production units, including
floating platforms and floating production, storage and offloading vessels, and
on other marine vessels, floating rigs and jack-ups. We believe that sales of
our equipment for offshore infrastructure development and new rig construction
will be important sources of future revenues. Our products and services include:

     - flexible bearings and connector products;

     - subsea pipeline products;

     - marine winches, mooring and lifting systems and rig equipment;

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

     - other products and services.

                                       S-1


     We have facilities in Arlington, Houston and Lampasas, Texas; Houma,
Louisiana; Tulsa, Oklahoma; Scotland; Brazil; England; and Singapore that
support our offshore products segment.

  WELL SITE SERVICES

     Our well site services segment provides a broad range of products and
services that are used to establish and maintain the flow of oil and gas from a
well throughout its lifecycle. Our services include workforce accommodations,
catering and logistics services, rental equipment, drilling services and
workover services. We use our workforce accommodation facilities, rental
equipment, fleet of workover and drilling rigs and related equipment to service
well sites for oil and natural gas companies. Our products and services are used
in both onshore and offshore applications through the exploration, development,
production and abandonment phases of a well's life.

     Workforce Accommodations, Catering and Logistics.  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 workforce
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.

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

     - wireline and coiled tubing pressure control equipment;

     - pipe recovery systems; and

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

     As of December 31, 2002, we provided rental equipment at 19 U.S.
distribution points in Texas, Louisiana, Oklahoma, Mississippi, New Mexico and
Wyoming.

     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. We have a total of 15 semi-automatic
drilling rigs with hydraulic pipe handling booms and lift capacities ranging
from 200,000 to 300,000 pounds.

     Workover Services.  We provide our workover products and services primarily
to customers in the U.S., Venezuela, the Middle East and West Africa, for both
onshore and offshore applications. Our hydraulic workover units are used for
workover operations and snubbing operations in pressure situations. Our
hydraulic drilling and workover rigs are also capable of providing underbalanced
drilling and workover services. As of December 31, 2002, we had 27 "stand alone"
hydraulic workover units.

  TUBULAR SERVICES

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

     - distribute premium tubing and casing;

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

     - 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 domestic and
foreign manufacturers of oilfield specialty pipe, we deliver
                                       S-2


tubular products and ancillary services to oil and gas companies, drilling
contractors and consultants predominantly in the United States. We do not
manufacture any of the tubular goods that we distribute. We operate our tubular
services segment from a total of eight facilities and have offices located near
areas of oil and gas exploration and development activity.

     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. Our A-Z Terminal is on 109 acres, is an
ISO 9002-certified facility and 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 threading, inspection, cleaning, cutting,
logistics, rig returns, installation of float equipment and non-destructive
testing.

OUR GROWTH STRATEGY

     We intend to grow our revenue and profitability while continuing to provide
our customers with dependable, high-quality products and services. We believe we
can implement our growth strategy largely using our existing facilities. The key
elements of our growth strategy are to:

     - capitalize on deepwater development and natural gas drilling and
       production activity;

     - continue to expand our product and service offering geographically;

     - increase capacity in several equipment constrained business lines; and

     - increase market share and expand our product offerings through
       acquisitions.

RISK FACTORS

     Prospective investors should carefully consider the matters described under
"Risk Factors," as well as the other information in this prospectus supplement
and the accompanying prospectus, including that sales of our products and
services depend on oil and gas industry expenditure levels, our results may
fluctuate based on the cyclicality of the oil and gas industry and political and
economic disruptions in the foreign countries in which we operate may adversely
affect our results.

RECENT DEVELOPMENTS

  FOURTH QUARTER 2002 RESULTS

     On February 3, 2003, we announced our results of operations for the quarter
and year ended December 31, 2002. Net income for the fourth quarter of 2002 was
$11.5 million, or $0.23 per diluted share, compared to net income of $11.1
million, or $0.23 per diluted share, in the fourth quarter of 2001. The 2002
results reflect our adoption of Statement of Financial Accounting Standards No.
142, "Goodwill and Other Intangible Assets," which eliminated the amortization
of goodwill effective January 1, 2002. We amortized $1.9 million, or $0.04 per
diluted share, of goodwill in the fourth quarter of 2001. Additionally, our
effective tax rate increased from 5.0% in the fourth quarter of 2001 to 22.3% in
the most recent quarter, negatively impacting the fourth quarter 2002 results by
approximately $0.05 per diluted share. For a further discussion of our effective
tax rate, see Note 3 to our summary unaudited financial information set forth
under the caption "-- Summary Unaudited Financial Information" below.

     For the fourth quarter of 2002, we had revenues of $160.8 million,
operating income of $15.8 million and operating income before depreciation and
amortization, or EBITDA as defined, of $22.3 million, compared to revenues of
$179.4 million, operating income of $12.7 million and EBITDA as defined of $20.3
million for the fourth quarter of 2001. Our well site services and tubular
services segments were negatively impacted in the fourth quarter of 2002 by the
15.7% year-over-year decline in the average U.S. rig count and by Gulf of Mexico
tropical storms. In addition, our well site services segment was

                                       S-3


negatively impacted by a delayed start of the Canadian winter drilling season
due to warm weather and by reduced manufacturing contributions from our Canadian
accommodations business. Our well site services segment generated revenues and
operating income of $48.1 million and $6.9 million, respectively, in the fourth
quarter of 2002, representing declines of $10.2 million, or 17.5%, and $3.2
million, or 31.8%, respectively, compared to the fourth quarter of 2001. Our
tubular services segment generated $56.8 million of revenues and $2.9 million of
operating income in the fourth quarter of 2002, representing declines of $28.2
million, or 33.2%, and $0.1 million, or 4.7%, respectively, compared to the
fourth quarter of 2001. However, increased demand in our offshore products
segment generated $55.9 million of revenues and $7.7 million of operating
income, representing increases of $19.9 million, or 55.1%, and $5.8 million, or
305.7%, respectively, compared to the fourth quarter of 2001.

     For a further discussion of EBITDA as defined, see Note 4 to our summary
unaudited financial information set forth under the caption "-- Summary
Unaudited Financial Information" below.

 OFFSHORE PRODUCTS BACKLOG

     Despite strong product shipments in the fourth quarter of 2002, backlog in
our offshore products segment was $100.1 million at December 31, 2002, compared
to $104.0 million at September 30, 2002 and $72.4 million at December 31, 2001.
We expect over 95% of our backlog as of December 31, 2002 to be completed in
2003. Our offshore products backlog consists of firm customer purchase orders
for which satisfactory credit or financing arrangements exist and delivery is
scheduled. In some instances, these purchase orders are cancelable by the
customer, subject to the payment of termination fees and/or the reimbursement of
our costs incurred. Our backlog as of any particular date may not be indicative
of our actual operating results for any future period.

 AMENDMENT TO CREDIT FACILITY

     On December 12, 2002, we amended our $150 million senior secured revolving
credit facility to extend the maturity and increase the committed availability,
among other things. The maturity was extended one year to January 25, 2005, and
the committed availability was increased to $168 million from $150 million. As
of January 27, 2003, we had approximately $38 million of unused borrowing
capacity under the facility.

 ACQUISITIONS

     In the third quarter of 2002, we completed the following five acquisitions,
two of which were in our well site services segment and three of which were in
our offshore products segment:

     - Edge Wireline Rentals Inc., a Louisiana-based supplier of rental tools to
       the oil and gas service industry;

     - J.V. Oilfield Rentals & Supply, Inc., a Louisiana-based supplier of
       rental tools to the oil and gas service industry;

     - Barlow Hunt, Inc., an Oklahoma-based elastomer molding company;

     - certain assets and related liabilities of Big Inch Marine Services, Inc.,
       a Texas-based subsidiary of Stolt Offshore, Inc., which provides subsea
       pipeline equipment and repair services; and

     - Applied Hydraulic Systems, Inc., a Louisiana-based offshore crane
       manufacturer and crane repair service provider.

     The total consideration for these acquisitions was approximately $70
million, which was financed primarily with borrowings under our credit facility.

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

(1) The unaudited pro forma statements of operations for 1999, 2000 and 2001 and
    other financial data give effect to:

     - our initial public offering of 10,000,000 shares at $9.00 per share in
       February 2001 and the application of the net proceeds to us;

     - our issuance of 4,275,555 shares of common stock to SCF-III, L.P. and
       SCF-IV, L.P., private equity funds that focus on investments in the
       energy industry (together, "SCF"), in exchange for approximately $36.0
       million of our indebtedness held by SCF effected in connection with our
       initial public offering;

     - the three-for-one reverse stock split of Oil States common stock effected
       in connection with our initial public offering;

     - the combination of Oil States, HWC Energy Services, Inc. and PTI Group,
       Inc. immediately prior to our initial public offering (the
       "Combination"), excluding the minority interest of each company, as
       entities under common control from the dates such common control was
       established using reorganization accounting, which yields results similar
       to pooling of interest accounting;

     - the acquisition of the minority interests of Oil States, HWC and PTI in
       the Combination using the purchase method of accounting as if the
       acquisition occurred on January 1, 1999, 2000 and 2001, respectively; and

     - the acquisition of Sooner, Inc. in the Combination using the purchase
       method of accounting as if the acquisition occurred on January 1, 1999,
       2000 and 2001, respectively.

(2) In June 2001, the Financial Accounting Standards Board issued Statement of
    Financial Accounting Standard ("SFAS") No. 142, "Goodwill and Other
    Intangible Assets," which we adopted effective January 1, 2002. Under SFAS
    142, goodwill and intangible assets deemed to have indefinite lives are no
    longer amortized but are subject to annual impairment tests. Accordingly,
    beginning in 2002, we no longer amortize goodwill. See "Risk
    Factors -- Risks Related to Our Operations -- If we have to write off a
    significant amount of goodwill, our earnings will be negatively affected."

(3) Our effective tax rate is affected by our net operating loss carry forwards.
    Our 2002 effective tax rate for financial reporting purposes was
    approximately 22%. Although there are a number of factors that could affect
    it, we currently estimate that our 2003 effective tax rate for financial
    reporting purposes will be approximately 30%. See "Part I -- Financial
    Information, Item 2. Management's Discussion and Analysis of Financial
    Condition and Results of Operations -- Tax Matters" in our Quarterly Report
    on Form 10-Q for the quarterly period ended September 30, 2002, which is
    incorporated by reference in the accompanying prospectus.

(4) EBITDA as defined consists of operating income before goodwill amortization,
    depreciation and other amortization expense. EBITDA as defined is not a
    measure of financial performance under generally accepted accounting
    principles. You should not consider it in isolation from or as a substitute
    for net income or cash flow measures prepared in accordance with generally
    accepted accounting principles or as a measure of profitability or
    liquidity. Additionally, EBITDA as defined may not be comparable to other
    similarly titled measures of other companies. We have included EBITDA as
    defined as a supplemental disclosure because our management believes that it
    provides useful information regarding our ability to service debt and to
    fund capital expenditures and provides investors a helpful measure for
    comparing our operating performance with the performance of other companies
    that have different financing and capital structures or tax rates. We use
    EBITDA as defined to compare and to monitor the performance of each of our
    segments to other comparable public companies and as a benchmark for the
    award of incentive compensation under our annual incentive compensation
    plan.

     We believe that operating income is the financial measure calculated and
     presented in accordance with generally accepted accounting principles that
     is most directly comparable to EBITDA as defined. The following table
     reconciles EBITDA as defined with our operating income, as derived from our
     unaudited financial information:

                                  RISK FACTORS

     Before you invest in our common stock, you should understand the high
degree of risk involved. You should consider carefully the following risks and
other information in this prospectus supplement and the accompanying prospectus,
including the documents incorporated by reference, before you decide to purchase
shares of our common stock. If any of the adverse events described below
actually occur, our business, financial condition and operating results could be
materially adversely affected. As a result, the trading price of our common
stock could decline and you may lose part or all of your investment.

RISKS RELATED TO OUR 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:

     - the level of production;

     - the levels of oil and gas inventories;

     - the expected cost of developing new reserves;

     - the cost of producing oil and gas;

     - the availability of transportation infrastructure;

     - depletion rates;

     - the level of drilling activity;

     - worldwide economic activity;

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

     - the impact of armed hostilities involving one or more oil producing
       nations;

     - the cost of developing alternate energy sources;

     - environmental regulation; and

     - tax policies.

 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 and gas prices have been and are expected to remain volatile. This
volatility causes oil and gas companies and drilling contractors to change their
strategies and expenditure levels. We have experienced in the past, and may
experience in the future, significant fluctuations in operating results based on
these changes.
                                       S-9


 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, South America and the Middle East. Our operations in these areas
increase our exposure to risks of war, terrorist attacks, local economic
conditions, political disruption, civil disturbance and governmental policies
that may:

     - disrupt our operations;

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

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

     - limit access to markets for periods of time.

 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.

 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. ALSO, IF STEEL MILLS WERE TO SELL A SUBSTANTIAL AMOUNT
 OF GOODS DIRECTLY TO CUSTOMERS IN THE UNITED STATES, OUR RESULTS OF OPERATIONS
 COULD BE ADVERSELY IMPACTED.

     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 than would otherwise occur if foreign imports
were allowed into the U.S. 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 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.

     We do not manufacture any of the tubular goods that we distribute.
Historically, users of tubular goods in the United States, in contrast to
outside the United States, have purchased tubular goods from a distributor. If
customers were to purchase tubular goods directly from steel mills, our results
of operations could be adversely impacted.

 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.

                                       S-10


     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:

     - issuance of administrative, civil and criminal penalties;

     - denial or revocation of permits or other authorizations;

     - reduction or cessation in operations; and

     - 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:

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

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

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

     - we may incur losses from interruption of our business that exceed our
       insurance coverage.

     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.

 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, including those relating to the activities of businesses that we
have sold and to the activities of businesses that we have acquired, even though
these activities may have occurred prior to our acquisition of such businesses.
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 a 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. See "Part II -- Other Information, Item
1. Legal Proceedings" in our Quarterly Report on Form 10-Q for the quarterly
period ended September 30, 2002, which is incorporated by reference in the
accompanying prospectus.

 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. Our business
will be adversely affected to the extent that these providers are successful in
reducing purchases of our products and services.

RISKS RELATED TO OUR OPERATIONS

 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 workforce accommodations, catering and 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
                                       S-11


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 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(R) 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. 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.

 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 and the value
of our intellectual property rights may be reduced.

 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.

     As of December 31, 2002, goodwill represented approximately 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. Current accounting standards, which
were effective January 1, 2002, 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. See Note 2 to our Unaudited Consolidated,
Combined and Pro Forma Financial Statements included in our Quarterly Report on
Form 10-Q for the quarterly period ended September 30, 2002, which is
incorporated by reference in the accompanying prospectus.

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

     During 2002, we purchased from a single supplier approximately 44% of the
tubular goods we distributed and from three suppliers approximately 70% 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.

                                       S-12


RISKS RELATED TO OUR RELATIONSHIP WITH SCF

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

     Prior to this offering, SCF holds approximately 62.3% of the outstanding
common stock of our company. Following this offering SCF will hold approximately
47.9% of the outstanding common stock of our company (or 45.7% if the
underwriters exercise the overallotment option in full). 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 effectively 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 yours, and SCF
may vote its common stock in a manner that may adversely affect you.

 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.

 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 YOUR 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 your 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:

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

                                       S-13


     - such entity or individual may pursue the opportunity as that entity or
       individual sees fit, unless:

      - 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

      - 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.

  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 following this offering, 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. SCF has entered into the lock-up
agreement described in "Underwriting."

                                DIVIDEND POLICY

     We have not declared or paid any cash dividends on our common stock since
our initial public offering and do not intend to declare or pay any cash
dividends on our common stock in the foreseeable future. Instead, we currently
intend to retain our earnings, if any, to finance our business and to use for
general corporate purposes. Furthermore, our existing credit facilities restrict
the payment of dividends. Any future determination as to the declaration and
payment of dividends will be at the discretion of our board of directors and
will depend on then existing conditions, including our financial condition,
results of operations, contractual restrictions, capital requirements, business
prospects and other factors that our board of directors considers relevant.

(1) 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-III, L.P. and SCF-IV, L.P. Accordingly, Mr. Simmons may be deemed to
    have voting and dispositive power over the shares owned by SCF-III, L.P. and
    SCF-IV, L.P. Prior to this offering, SCF-III, L.P. and SCF-IV, L.P. together
    own approximately 62.3% of our outstanding common stock. Prior to the
    Combination, SCF-III, L.P. and SCF-IV, L.P. together owned a majority of the
    outstanding common stock of each of Oil States, HWC, Sooner and PTI and
    engaged in certain transactions with Oil States, HWC, Sooner and PTI,
    including the acquisition of their debt and equity securities, as more fully
    described in our proxy statement for our 2002 annual meeting of
    stockholders. For a further discussion of the relationship of SCF-III, L.P.
    and SCF-IV, L.P. to our company, see "Risk Factors -- Risks Related to Our
    Relationship with SCF."

(2) Assumes that the underwriters do not exercise their overallotment option. If
    the underwriters fully exercise their overallotment option, SCF-III, L.P.
    and SCF-IV, L.P. would sell an additional 752,093 and 297,907 shares,
    respectively, and would beneficially own 32.7% and 13.0%, respectively, of
    our common stock after the offering.

                              REGISTRATION RIGHTS

     We have entered into an amended and restated registration rights agreement
with SCF, other stockholders of Oil States and the former shareholders of HWC
and Sooner that held registration rights with respect to their shares of common
stock of these companies. This agreement gives SCF the right, on five occasions,
to demand that we register all or any portion of their shares of our common
stock for sale under the Securities Act. The shares to be included in any demand
registration by SCF must have an estimated aggregate gross offering price of at
least $50.0 million. Despite a registration demand by SCF, we may delay filing
of the registration statement to register its shares of our common stock for a
maximum of 45 days from the date we receive the registration demand if:

     - at the time we receive the registration demand, we are engaged in
       confidential negotiations or other confidential business activities that
       we would be required to disclose in the registration statement and that
       we would not otherwise be required to disclose, and our board of
       directors determines in good faith that such disclosure would not be in
       our best interests or the best interests of our stockholders; or

     - prior to receiving the registration demand, our board of directors has
       determined to undertake a registered public offering of our securities
       and we have taken substantial steps and are proceeding with reasonable
       diligence to effect the offering.

In addition, SCF may not require us to file a registration statement within 180
days after the effectiveness of a registration statement related to a demand
registration made by SCF. Further, if we propose to register any of our common
stock under the Securities Act, except for shares of common stock issued in
connection with acquisitions and benefits plans, or if SCF exercises a demand,
the other holders of registration rights under the registration rights agreement
will have the right to include their shares of common stock in the registration,
subject to limitations.

     SCF has agreed not to exercise its registration rights for a period of 90
days after the date of this prospectus supplement without the prior written
consent of Credit Suisse First Boston LLC.

     The agreement provides customary registration procedures. We have agreed to
pay all costs and expenses, other than fees, discounts and commissions of
underwriters, brokers and dealers and capital gains, income and transfer taxes,
if any, related to the registration and sale of shares of our common stock by
any holder of registration rights under the registration rights agreement in any
registered offering. The rights of the holders of registration rights under the
registration rights agreement are assignable under limited circumstances and
terminate, other than the demand rights held by SCF, at any time when they and
their affiliates own less than 2% of our outstanding common stock and are
eligible to sell such common stock pursuant to Rule 144(k) under the Securities
Act. The demand rights held by SCF terminate in February 2011.

     The registration rights agreement contains customary indemnification and
contribution provisions by us for the benefit of the selling stockholders and
any underwriters. Each selling stockholder has agreed to indemnify us and any
underwriter solely with respect to information provided by the stockholder, with
such indemnification being limited to the net proceeds from the offering
received by the stockholder.

               MATERIAL UNITED STATES FEDERAL TAX CONSEQUENCES TO
                        NON-U.S. HOLDERS OF COMMON STOCK

     The following is a general discussion of the material U.S. federal income
and estate tax considerations with respect to the ownership and disposition of
common stock applicable to Non-U.S. Holders. For purposes of this discussion, a
"Non-U.S. Holder" is any beneficial owner of common stock other than:

     - a citizen or resident of the United States;

     - a corporation (or other entity taxed as a corporation for U.S. federal
       income tax purposes) created or organized in the United States or under
       the laws of the United States or of any state thereof;

     - an estate, the income of which is includible in gross income for U.S.
       federal income tax purposes regardless of its source; or

     - a trust whose administration is subject to the primary supervision of a
       United States court and which has one or more United States persons who
       have the authority to control all substantial decisions of the trust, or
       a trust in existence on August 20, 1996 that has elected to continue to
       be treated as a "United States person" (as defined for U.S. federal
       income tax purposes).

     In case of shares of our common stock held by a partnership, the tax
treatment of a partner generally will depend upon the status of the partner as a
Non-U.S. Holder and the activities of the partnership. This discussion is based
on current provisions of the Internal Revenue Code, Treasury Regulations
promulgated under the Internal Revenue Code, judicial opinions, published
positions of the Internal Revenue Service, and all other applicable authorities,
all of which are subject to change, possibly with retroactive effect. This
discussion does not address all aspects of income and estate taxation or any
aspects of state, local, or non-U.S. taxes, nor does it consider any specific
facts or circumstances that may apply to particular Non-U.S. Holders that may be
subject to special treatment under the U.S. federal tax laws, such as insurance
companies, tax-exempt organizations, financial institutions, brokers, dealers in
securities, and U.S. expatriates.

     You are urged to consult your tax advisor regarding the U.S. federal,
state, local and non-U.S. income and other tax considerations of acquiring,
holding and disposing of shares of our common stock.

DIVIDENDS

     In general, dividends paid to a Non-U.S. Holder will be subject to U.S.
withholding tax at a rate of 30% of the gross amount, or a lower rate prescribed
by an applicable income tax treaty, unless the dividends are effectively
connected with a trade or business carried on by the Non-U.S. Holder within the
United States (or, in the case of an applicable income tax treaty, are
attributable to a permanent establishment in the United States). Dividends that
are effectively connected with such a U.S. trade or business (or attributable to
a permanent establishment in the United States) generally will not be subject to
U.S. withholding tax if the Non-U.S. Holder files the required forms, including
Internal Revenue Service Form W-8ECI or any successor form, with the payor of
the dividend, and instead will be subject to U.S. federal income tax on a net
income basis, in the same manner as if the Non-U.S. Holder were a resident of
the United States. A Non-U.S. Holder that is a corporation may be subject to an
additional branch profits tax at a rate of 30%, or such lower rate as may be
specified by an applicable income tax treaty, on the repatriation from the
United States of its "effectively connected earnings and profits," with certain
adjustments. A Non-U.S. Holder is required to satisfy certification requirements
in order to claim a reduced rate of withholding tax under an applicable income
tax treaty, including the filing of Internal Revenue Service Form W-8BEN or any
successor form. In the case of common stock held by a foreign partnership, the
certification requirement generally is applied to the partners of the
partnership, unless the partnership agrees to become a "withholding foreign
partnership," and the partnership agrees to provide specified information.

                                       S-18


     A Non-U.S. Holder of common stock that is eligible for a reduced rate of
U.S. federal income tax withholding under a tax treaty may obtain a refund of
any excess amounts withheld by filing an appropriate claim for refund with the
Internal Revenue Service.

GAIN ON SALE OR OTHER DISPOSITION OF COMMON STOCK

     In general, a Non-U.S. Holder will not be subject to U.S. federal income
tax on any gain realized upon the sale or other taxable disposition of shares of
common stock so long as:

     - the gain is not effectively connected with a trade or business carried on
       by the Non-U.S. Holder within the United States;

     - if the Non-U.S. Holder is an individual, the Non-U.S. Holder holds shares
       of common stock as a capital asset, and either is not present in the
       United States for 183 days or more in the taxable year of disposition or
       does not have a "tax home" in the United States for U.S. federal income
       tax purposes and meets other requirements;

     - the Non-U.S. Holder is not subject to tax under the provisions of the
       Internal Revenue Code regarding the taxation of U.S. expatriates; and

     - we are not a United States real property holding corporation.

     We believe that we are not currently a United States real property holding
corporation, and we do not expect to become one in the future based on our
anticipated business operations.

ESTATE TAX

     Common stock owned or treated as owned by an individual who is not a
citizen or resident, as defined for U.S. federal estate tax purposes, of the
United States at the time of death will be includible in the individual's gross
estate for U.S. federal estate tax purposes and therefore may be subject to U.S.
federal estate tax, unless an applicable estate tax treaty provides otherwise.

INFORMATION REPORTING, BACKUP WITHHOLDING AND OTHER REPORTING REQUIREMENTS

     We must report annually to the Internal Revenue Service and to each
non-U.S. Holder the amount of dividends paid to, and the tax withheld with
respect to, each Non-U.S. Holder. These reporting requirements apply regardless
of whether withholding was reduced or eliminated by an applicable tax treaty.
Copies of this information also may be made available under the provisions of a
specific treaty or agreement with the tax authorities in the country in which
the Non-U.S. Holder resides or is established.

     U.S. backup withholding tax is imposed at the rate of 30% on applicable
payments to persons that fail to furnish the information required under the U.S.
information reporting requirements. The backup withholding tax rate is scheduled
to be reduced to 29% for 2004 and 2005 and to 28% for 2006 through 2010, after
which the rate will become 31%. The payment of dividends or the payment of
proceeds from the disposition of common stock to a Non-U.S. Holder may be
subject to backup withholding unless the recipient certifies under penalties of
perjury as to its foreign status and certain other requirements are met, or
otherwise establishes an exemption. The payment of proceeds from the disposition
of common stock to or through a non-U.S. office of a broker generally will not
be subject to backup withholding or information reporting; however, such a
payment of proceeds may be subject to information reporting, but not backup
withholding, if the broker is:

     - a United States person;

     - a "controlled foreign corporation" for U.S. federal income tax purposes;

     - a foreign person 50% or more of whose gross income for its three taxable
       years prior to the payment was effectively connected with a U.S. trade or
       business; or

     - a foreign partnership, if at any time during its tax year either:

                                       S-19


        - one or more of its partners are United States persons who in the
          aggregate hold more than 50% of the income or capital interests in the
          partnership or

        - the foreign partnership is engaged in a U.S. trade or business.

     Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules from a payment to a Non-U.S. Holder can be refunded or
credited against the Non-U.S. Holder's U.S. federal income tax liability, if
any, provided that the required information is furnished to the Internal Revenue
Service in a timely manner.

     Each prospective Non-U.S. Holder of common stock should consult that
holder's own tax adviser with respect to the federal, state, local and foreign
tax consequences of the acquisition, ownership and disposition of our common
stock.

                                  UNDERWRITING

     Under the terms and subject to the conditions contained in an underwriting
agreement dated February 13, 2003, the selling stockholders have agreed to sell
to the underwriters named below, for whom Credit Suisse First Boston LLC and
Goldman, Sachs & Co. are acting as representatives, the following respective
numbers of shares of common stock.

     The underwriting agreement provides that the underwriters are obligated to
purchase all the shares of common stock in the offering if any are purchased,
other than those shares covered by the over-allotment option described below.
The underwriting agreement also provides that if an underwriter defaults, the
purchase commitments of non-defaulting underwriters may be increased or the
offering may be terminated.

     The selling stockholders have granted to the underwriters a 30-day option
to purchase on a pro rata basis up to an aggregate of 1,050,000 additional
outstanding shares at the initial public offering price less the underwriting
discounts and commissions. The option may be exercised only to cover any over-
allotments of common stock.

     The underwriters propose to offer the shares of common stock initially at
the public offering price on the cover page of this prospectus supplement and to
selling group members at that price less a selling concession of $0.35 per
share. The underwriters and selling group members may allow a discount of $0.10
per share on sales to other broker/dealers. After the initial public offering,
the representatives may change the public offering price and concession and
discount to broker/dealers.

     We have agreed to pay all of the costs and expenses of the selling
stockholders related to the offering of the shares, other than the fees,
discounts and commission of the underwriters and any capital gains, income and
transfer taxes. The following table summarizes the compensation and estimated
expenses that we and the selling stockholders will pay:

without the prior written consent of Credit Suisse First Boston LLC for a period
of 90 days after the date of this prospectus supplement, except for (1)

                                       S-21


     SCF-III, L.P., SCF-IV, L.P. and our executive officers and directors have
agreed that they will not offer, sell, contract to sell, pledge or otherwise
dispose of, directly or indirectly, any shares of our common stock or securities
convertible into or exchangeable or exercisable for any shares of our common
stock, enter into a transaction that would have the same effect, or enter into
any swap, hedge or other arrangement that transfers, in whole or in part, any of
the economic consequences of ownership of our common stock, whether any of these
transactions are to be settled by delivery of our common stock or other
securities, in cash or otherwise, or publicly disclose the intention to make any
offer, sale, pledge or disposition, or to enter into any transaction, swap,
hedge or other arrangement, without, in each case, the prior written consent of
Credit Suisse First Boston LLC for a period of 90 days after the date of this
prospectus supplement.

     We and the selling stockholders have agreed to indemnify the underwriters
against liabilities under the Securities Act of 1933, or contribute to payments
that the underwriters may be required to make in that respect.

     The shares of common stock are listed on The New York Stock Exchange under
the symbol "OIS."

     Some of the underwriters and their respective affiliates perform from time
to time various financial advisory, commercial banking and investment banking
services for us and our affiliates in the ordinary course of business, for which
they received or will receive customary fees.

     In connection with the offering, the underwriters may engage in stabilizing
transactions, over-allotment transactions, syndicate covering transactions and
penalty bids in accordance with Regulation M under the Securities Exchange Act
of 1934.

     - Stabilizing transactions permit bids to purchase the underlying security
       so long as the stabilizing bids do not exceed a specified maximum.

     - Over-allotment involves sales by the underwriters of shares in excess of
       the number of shares the underwriters are obligated to purchase, which
       creates a syndicate short position. The short position may be either a
       covered short position or a naked short position. In a covered short
       position, the number of shares over-allotted by the underwriters is not
       greater than the number of shares that they may purchase in the
       over-allotment option. In a naked short position, the number of shares
       involved is greater than the number of shares in the over-allotment
       option. The underwriters may close out any covered short position by
       either exercising their over-allotment option and/or purchasing shares in
       the open market.

     - Syndicate covering transactions involve purchases of the common stock in
       the open market after the distribution has been completed in order to
       cover syndicate short positions. In determining the source of shares to
       close out the short position, the underwriters will consider, among other
       things, the price of shares available for purchase in the open market as
       compared to the price at which they may purchase shares through the
       over-allotment option. If the underwriters sell more shares than could be
       covered by the over-allotment option, a naked short position, the
       position can only be closed out by buying shares in the open market. A
       naked short position is more likely to be created if the underwriters are
       concerned that there could be downward pressure on the price of the
       shares in the open market after pricing that could adversely affect
       investors who purchase in the offering.

     - Penalty bids permit the representatives to reclaim a selling concession
       from a syndicate member when the common stock originally sold by the
       syndicate member is purchased in a stabilizing or syndicate covering
       transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids
may have the effect of raising or maintaining the market price of our common
stock or preventing or retarding a decline in the market price of the common
stock. As a result, the price of our common stock may be higher than the price
that might otherwise exist in the open market. These transactions may be
effected on The New York Stock Exchange or otherwise and, if commenced, may be
discontinued at any time.

                                       S-22


     A prospectus in electronic format may be made available on the web sites
maintained by one or more of the underwriters, or selling group members, if any,
participating in this offering. The underwriters may agree to allocate a number
of shares to underwriters and selling group members for sale to their online
brokerage account holders. Internet distributions will be allocated by the
underwriters and selling group members that will make internet distributions on
the same basis as other allocations.

                          NOTICE TO CANADIAN RESIDENTS

RESALE RESTRICTIONS

     The distribution of the common stock in Canada is being made only on a
private placement basis exempt from the requirement that we and the selling
stockholders prepare and file a prospectus with the securities regulatory
authorities in each province where trades of common stock are made. Any resale
of the common stock in Canada must be made under applicable securities laws
which will vary depending on the relevant jurisdiction, and which may require
resales to be made under available statutory exemptions or under a discretionary
exemption granted by the applicable Canadian securities regulatory authority.
Purchasers are advised to seek legal advice prior to any resale of the common
stock.

REPRESENTATIONS OF PURCHASERS

     By purchasing common stock in Canada and accepting a purchase confirmation
a purchaser is representing to us, the selling stockholders and the dealer from
whom the purchase confirmation is received that:

     - the purchaser is entitled under applicable provincial securities laws to
       purchase the common stock without the benefit of a prospectus qualified
       under those securities laws;

     - where required by law, that the purchaser is purchasing as principal and
       not as agent; and

     - the purchaser has reviewed the text above under Resale Restrictions.

RIGHTS OF ACTION -- ONTARIO PURCHASERS ONLY

     Under Ontario securities legislation, a purchaser who purchases a security
offered by this prospectus supplement during the period of distribution will
have a statutory right of action for damages, or while still the owner of the
shares, for rescission against us and the selling stockholders in the event that
this prospectus supplement contains a misrepresentation. A purchaser will be
deemed to have relied on the misrepresentation. The right of action for damages
is exercisable not later than the earlier of 180 days from the date the
purchaser first had knowledge of the facts giving rise to the cause of action
and three years from the date on which payment is made for the shares. The right
of action for rescission is exercisable not later than 180 days from the date on
which payment is made for the shares. If a purchaser elects to exercise the
right of action for rescission, the purchaser will have no right of action for
damages against us or the selling stockholders. In no case will the amount
recoverable in any action exceed the price at which the shares were offered to
the purchaser and if the purchaser is shown to have purchased the securities
with knowledge of the misrepresentation, we and the selling stockholders will
have no liability. In the case of an action for damages, we and the selling
stockholders will not be liable for all or any portion of the damages that are
proven to not represent the depreciation in value of the shares as a result of
the misrepresentation relied upon. These rights are in addition to, and without
derogation from, any other rights or remedies available at law to an Ontario
purchaser. The foregoing is a summary of the rights available to an Ontario
purchaser. Ontario purchasers should refer to the complete text of the relevant
statutory provisions.

ENFORCEMENT OF LEGAL RIGHTS

     All of our directors and officers as well as the experts named herein and
the selling stockholders may be located outside of Canada and, as a result, it
may not be possible for Canadian purchasers to effect
                                       S-23


service of process within Canada upon us or those persons. All or a substantial
portion of our assets and the assets of those persons may be located outside of
Canada and, as a result, it may not be possible to satisfy a judgment against us
or those persons in Canada or to enforce a judgment obtained in Canadian courts
against us or those persons outside of Canada.

TAXATION AND ELIGIBILITY FOR INVESTMENT

     Canadian purchasers of common stock should consult their own legal and tax
advisors with respect to the tax consequences of an investment in the common
stock in their particular circumstances and about the eligibility of the common
stock for investment by the purchaser under relevant Canadian legislation.

                                 LEGAL MATTERS

           CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

     We include the following cautionary statement to take advantage of the
"safe harbor" provisions of the Private Securities Litigation Reform Act of 1995
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, capital expenditures, projected costs, plans and objectives of
management for future operations and possible future acquisitions, 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, we, or our management, express 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 factors that could cause actual results to differ
materially from those expressed in any forward-looking statement made by, or on
behalf of, our company:

     - fluctuations in the prices of oil and gas;

     - the level of drilling activity;

     - the level of offshore oil and gas developmental activities;

     - general economic conditions;

     - our ability to find and retain skilled personnel;

     - the availability of capital; and

     - the other factors identified under the captions "Risks Related to Oil
       States' Business Generally" and "Risks Related to Oil States' Operations"
       in our annual report on Form 10-K for the year ended December 31, 2001,
       which is incorporated by reference herein.

L.P. owned a majority interest in Sooner. SCF-III, L.P. and SCF-IV, L.P. are
private equity funds that focus on investments in the energy industry. We refer
to SCF-III, L.P. and SCF-IV, L.P. collectively as "SCF." Unless we have
indicated otherwise, or the context otherwise requires, references to "Oil
States," "we," "us" and "our" or similar terms are to Oil States International,
Inc. and its subsidiaries following the Combination.

     The foregoing information about us is only a general summary and is not
intended to be comprehensive. For additional information about us and our
business segments, you should refer to the information described under the

     Our principal executive offices are located at Three Allen Center, 333 Clay

is (713) 652-0582.

                                USE OF PROCEEDS

     We will not receive any proceeds from the sale of the shares of common
stock by the selling stockholders.

                          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 May 29, 2002, we had 48,348,882 shares of common
stock, including up to 1,225,830 shares of our common stock issuable upon
exchange of exchangeable shares issued by one of our Canadian subsidiaries, 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 outstanding
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:

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

     - 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 May 15, 2002, there were 83 holders of record of our common stock.

                                        1


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:

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

     - 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.

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
May 14, 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 Group Inc. held by
Canadian residents were exchanged for exchangeable shares issued by our
subsidiary PTI HoldCo. The exchangeable shares may generally be exchanged at any
time 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 May
29, 2002, there are 1,225,830 exchangeable shares outstanding, which are
exchangeable for an equal number of 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:

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

     - 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:

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

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

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

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

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

     - PTI HoldCo elects to redeem all of the exchangeable shares, provided the
       request is made after either the third anniversary of the closing of our
       initial public offering and the number of outstanding

                                        2


       exchangeable shares is less than 10% of the number outstanding upon the
       closing of the Combination or the fourth anniversary of the closing of
       our initial public offering and the number of outstanding exchangeable
       shares is less than 20% of the number outstanding upon the closing of the
       Combination;

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

     - 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 relating to the exchangeable shares or
       the voting and exchange trust agreement relating to the exchangeable
       shares; or

     - 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:

     - 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;

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

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

     - 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 receive shares of our common stock in exchange 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 a trustee for the benefit of the holders of the exchangeable shares described
above. Except as otherwise required by law or our certificate of incorporation:

     - 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;

                                        3


     - 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 our
       common stock issuable upon the exchange of the exchangeable shares held
       by that holder;

     - 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

     - 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:

     - 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

     - 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:

     - 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

     - 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.

                                        4


     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:

     - 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

     - 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).

     As a result of these provisions, 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 our bylaws and adopt new bylaws.
The holders of common stock may amend or repeal our bylaws and adopt new bylaws
by a majority vote.

                                        5


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:

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

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

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

     - 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

     Shares may be sold or distributed from time to time by the selling
stockholders. The selling stockholders may sell their shares at market prices
prevailing at the time of sale, at prices related to such prevailing market
prices, at negotiated prices, or at fixed prices, which may be changed. The
selling stockholders may accept or reject, in whole or in part, any proposed
purchase of shares, whether the purchase is to be made directly or through
agents.

     The selling stockholders may offer their shares at various times in one or
more of the following transactions:

     - in underwritten transactions;

     - in ordinary brokers' transactions and transactions in which the broker
       solicits purchasers;

     - in transactions involving cross or block trades or otherwise on the New
       York Stock Exchange;

     - in transactions "at the market" to or through market makers in our common
       stock or into an existing market for the common stock;

     - in other ways not involving market makers or established trading markets,
       including direct sales of the shares to purchasers or sales of the shares
       effected through agents;

     - through transactions in options, swaps or other derivatives which may or
       may not be listed on an exchange;

     - in privately negotiated transactions;

     - in transactions to cover short sales; or

     - in a combination of any of the foregoing transactions.

The selling stockholders also may sell their shares in accordance with Rule 144
under the Securities Act of 1933 or in other transactions exempt from the
registration requirements of the Securities Act of 1933.

                                        7


     From time to time, the selling stockholders may pledge or grant a security
interest in some or all of the shares owned by them. If the selling stockholders
default in performance of their secured obligations, the pledged or secured
parties may offer and sell the shares from time to time by this prospectus. The
selling stockholders also may transfer and donate shares in other circumstances.
The number of shares beneficially owned by the selling stockholders will
decrease as and when they transfer or donate their shares or default in
performing obligations secured by their shares. The plan of distribution for the
shares offered and sold under this prospectus will otherwise remain unchanged,
except that the transferees, donees, pledgees, other secured parties or other
successors in interest will be selling stockholders for purposes of this
prospectus.

     The selling stockholders may sell short the common stock. The selling
stockholders may deliver this prospectus in connection with such short sales and
use the shares offered by this prospectus to cover such short sales. The selling
stockholders may enter into hedging transactions with broker-dealers. The
broker-dealers may engage in short sales of the common stock in the course of
hedging the positions they assume with the selling stockholders, including
positions assumed in connection with distributions of the shares by such broker-
dealers. The selling stockholders also may enter into option or other
transactions with broker-dealers that involve the delivery of shares to the
broker-dealers, who may then resell or otherwise transfer such shares. In
addition, the selling stockholders may loan or pledge shares to a broker-dealer,
which may sell the loaned shares or, upon a default by the selling stockholders
of the secured obligation, may sell or otherwise transfer the pledged shares.

     The selling stockholders may use brokers, dealers, underwriters or agents
to sell their shares. The persons acting as agents may receive compensation in
the form of commissions, discounts or concessions. This compensation may be paid
by the selling stockholders or the purchasers of the shares of whom such persons
may act as agent, or to whom they may sell as principal, or both. The
compensation as to a particular person may be less than or in excess of
customary commissions. The selling stockholders and any agents or broker-
dealers that participate with the selling stockholders in the offer and sale of
the shares may be deemed to be "underwriters" within the meaning of the
Securities Act of 1933. Any commissions they receive and any profit they realize
on the resale of the shares by them may be deemed to be underwriting discounts
and commissions under the Securities Act of 1933. Neither we nor the selling
stockholders can presently estimate the amount of such compensation.

     If the selling stockholders sell shares in an underwritten offering, the
underwriters may acquire the shares for their own account and resell the shares
from time to time in one or more transactions, including negotiated
transactions, at a fixed public offering price or at varying prices determined
at the time of sale. In such event, we will set forth in a supplement to this
prospectus the names of the underwriters and the terms of the transactions,
including any underwriting discounts, concessions or commissions and other items
constituting compensation of the underwriters and broker-dealers. The
underwriters from time to time may change any public offering price and any
discounts, concessions or commissions allowed or reallowed or paid to broker-
dealers. Unless otherwise set forth in a supplement, the obligations of the
underwriters to purchase the shares will be subject to certain conditions, and
the underwriters will be obligated to purchase all of the shares specified in
the supplement if they purchase any of the shares.

     We have informed the selling stockholders that during such time as they may
be engaged in a distribution of the shares they are required to comply with
Regulation M under the Securities Exchange Act of 1934. With exceptions,
Regulation M prohibits the selling stockholders, any affiliated purchasers and
other persons who participate in such a distribution from bidding for or
purchasing, or attempting to induce any person to bid for or purchase, any
security which is the subject of the distribution until the entire distribution
is complete.

     We have informed the selling stockholders that they are legally required to
deliver copies of this prospectus in connection with any sale of securities made
under this prospectus in accordance with applicable prospectus delivery
requirements.

     We will bear the expenses relating to this offering, other than any
underwriting fees, discounts and commissions, any capital gains, income or
transfer taxes, any out-of-pocket expenses of the selling stockholders (with
certain exceptions) or the fees and disbursements of counsel for any
underwriters.

                                        8


     We have agreed to indemnify the selling stockholders and their respective
controlling persons against certain liabilities, including certain liabilities
under the Securities Act of 1933. We will not receive any of the proceeds from
the sale by the selling stockholders of the shares offered by this prospectus.

     In order to comply with certain state securities laws, if applicable, the
shares offered by this prospectus will not be sold in a particular state unless
such shares have been registered or qualified for sale in such state or an
exemption from registration or qualification is available and complied with,
and, if so required, will only be sold in that state through registered or
licensed brokers or dealers.

     The shares of common stock originally issued by us to the selling
stockholders bear legends as to their restricted transferability. Upon the
effectiveness of the registration statement of which this prospectus is a part,
and the transfer by the selling stockholders of any of the shares pursuant to
this prospectus, new certificates representing those shares will be issued to
the transferee, free of any such legends unless otherwise required by law.
