              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


1. BASIS OF PRESENTATION

         The accompanying unaudited condensed consolidated financial statements
of OSCA, Inc. have been prepared in accordance with accounting principles
generally accepted in the United States for interim financial information and
with the instructions to Form 10-Q and Article 10 of Regulation S-X.
Accordingly, they do not include all the information and footnotes necessary for
a comprehensive presentation of financial position and results of operations.

         It is management's opinion, however, that all material adjustments
(consisting of normal recurring adjustments) have been made which are necessary
for a fair financial statement presentation. The results for the interim period
are not necessarily indicative of the results to be expected for the year.

2. PENDING MERGER AND ACQUISITIONS

Pending Merger

         On February 20, 2002, OSCA announced that it entered into a definitive
merger agreement with BJ Services Company. Under the terms of the agreement, BJ
Services will acquire all of the outstanding shares of OSCA for $28.00 per share
in cash. A special committee of independent members of OSCA's Board reviewed the
transaction on behalf of the public stockholders and recommended the transaction
to the complete OSCA Board, which then unanimously approved the merger
agreement. The transaction has a total equity value of approximately $420.0
million.

         Great Lakes Chemical Corporation, which owns approximately 53% of
OSCA's outstanding Common Stock and holds approximately 92% of the voting power,
has delivered its written stockholder consent approving the transaction with BJ
Services. The Great Lakes consent constitutes sufficient action by OSCA
stockholders to approve the transaction.

         The transaction is subject to regulatory approvals and OSCA has
received those approvals including those under the Hart-Scott-Rodino Antitrust
Improvements Act. OSCA has filed an information statement describing the
transaction with the Securities and Exchange Commission and mailed such
statement to OSCA stockholders on May 2, 2002. OSCA anticipates the merger to
close on May 31, 2002. There can be no assurance that the merger will be
consummated in accordance with the terms of the merger agreement, if at all.

Ancor Services, Inc.

         On January 3, 2002, OSCA completed the acquisition of substantially all
of the assets of Ancor Services, Inc. Ancor provided land based well stimulation
products and services to oil and natural gas production companies in East Texas
and North Louisiana. The assets acquired included a cement plant, specialized
vehicles, shop trucks and office furniture. The acquisition has been accounted
for using the purchase method of accounting pursuant to Statement of Financial
Accounting Standards No. 141,

                                       5

Business Combinations. Ancor's operating results since January 3, 2002 have been
consolidated with the operating results of OSCA. The acquired assets were
recorded at fair value with no goodwill being recorded. The purchase price for
the assets of approximately $1.9 million was paid utilizing available cash. As
part of the acquisition, OSCA also compensated the owners of Ancor for entering
into noncompete agreements and for performing consulting services. OSCA paid
$0.9 million toward the noncompete agreements at closing and has an obligation
to pay another $1.2 million over the next four years. The obligation due within
the next year of $0.3 million is included in accrued expenses and the long-term
obligation of $0.9 million is recorded in other long-term liabilities. The
consulting services of $0.8 million were paid at closing.

3. RESTRICTED CASH

         OSCA has deposited funds into a Rabbi Trust to cover some, but not all
of its obligations to senior management of OSCA should a change of control and
related termination of employment occur as a result of the merger with BJ
Services. The manager of the Rabbi Trust has invested the funds into a money
market account. If the merger is not completed, the funds will be returned to
OSCA's unrestricted cash account.

4. INVENTORIES

         The major components of OSCA's inventories are as follows:

5. GOODWILL AND INTANGIBLE ASSETS

         In June 2001, the Financial Accounting Standards Board issued
Statements of Financial Accounting Standards No. 141, Business Combinations, and
No. 142, Goodwill and Other Intangible Assets, effective for fiscal years
beginning after December 15, 2001 with early adoption permitted for companies
with fiscal years beginning after March 15, 2001. Under the new rules, goodwill
and intangible assets deemed to have indefinite lives will no longer be
amortized but will be subject to annual impairment tests in accordance with the
statements. Other intangible assets will continue to be amortized over their
useful lives.


                                       6

         OSCA adopted the new rules on accounting for goodwill and other
intangible assets effective January 1, 2002. OSCA has not yet performed its
transitional impairment test in conjunction with the adoption of SFAS 142.

         The following information relates to intangible assets still subject to
amortization under SFAS 142:

amortization expense of goodwill:

6. LITIGATION

         On September 18, 2000, OSCA was served with notice that a lawsuit was
filed against it and other named defendants on September 1, 2000 in the District
Court of Harris County, Texas. The action is brought by certain underwriting
syndicates of Lloyd's of London who claim to be subrogated to the claim of their
insureds, Newfield Exploration Company, Apache Oil Corporation, Continental Land
& Fur, and Fidelity Oil ("Plaintiffs"). The other defendants include High
Pressure Integrity, Inc. and Chalmers, Collins & Alwell, Inc. On September 8,
2000, OSCA filed a lawsuit against the Plaintiffs and the other defendants in
the United States District Court, Western District of Louisiana,
Lafayette-Opelousas Division. Other actions have also been filed in connection
with the same circumstances. All actions have now been consolidated into one
proceeding in the United States District Court, Southern District of Texas.


                                       7

         The lawsuits relate to a blowout of a well situated in the Gulf of
Mexico, offshore Louisiana, for which OSCA and others were engaged to perform
specific workover operations. In the Texas case, Plaintiffs seek damages,
interest and other costs in the approximate amount of $21.5 million, alleging
that OSCA and the other defendants breached their contracts to perform workover
operations, and were negligent in performing those operations. OSCA alleges
negligence against the Plaintiffs and other defendants and seeks damages,
interest, costs and general and equitable relief. OSCA filed a third party
demand against its underwriters and insurance broker in support of coverage of
claims asserted against OSCA in the Newfield matter.

         On April 4, 2002, a Federal Court jury in Houston, Texas reached a
verdict in the lawsuit against OSCA and other defendants. The jury found OSCA
and the other defendants responsible for those claims and found OSCA's share of
the damages to be approximately $13.3 million. A charge of $13.5 million has
been recorded in the first quarter of 2002, which includes $0.2 million of legal
fees incurred during the quarter.

         In connection with the lawsuit, OSCA asserted claims against its
insurers and insurance brokers in support of insurance coverage for this
incident. OSCA's insurers have denied coverage for this incident and a related
trial on these insurance coverage claims is scheduled to begin on May 20, 2002.
The court has not yet entered a final judgment on the liability claim and OSCA
does not expect final judgment to be entered until completion of the related
insurance trial. Any recoveries as a result of the insurance trial will be
recognized in the period in which recovery occurs.

7. LONG-TERM DEBT

         During the quarter ended March 31, 2002, OSCA borrowed approximately
$8.9 million under its $40.0 million credit facility with a bank. These
borrowings resulted in $35.9 million being outstanding as of March 31, 2002. The
borrowings were used to fund the restricted cash (note 3) and the Ancor
acquisition (note 2). As a result of the litigation verdict (note 6), OSCA was
in violation of covenants related to funded indebtedness and fixed charge
coverage ratios. On April 30, 2002, the lenders granted OSCA a modification in
the calculation of those two covenants which brought OSCA into compliance.

8. COMPREHENSIVE INCOME (LOSS)

         Comprehensive income (loss) was as follows (in thousands):

9. EARNINGS (LOSS) PER SHARE

         The computation of basic and diluted earnings (loss) per share is
determined by dividing net income (loss) by the number of shares as follows (in
thousands, except per share data):

         Restricted stock and options to purchase 101,548 shares of OSCA's
common stock were not included in the computation of diluted earnings (loss) per
share for the three months ended March 31, 2002 as the effect would have been
antidilutive due to the net loss for the period.

10. SEGMENT INFORMATION

         OSCA is organized into three global business segments:

                  -        Completion Fluids,

                  -        Completion Services and

                  -        Downhole Completion Tools.

         The segments are organized to offer a distinct but synergistic group of
products, technology and services.

         OSCA evaluates performance and allocates resources based on operating
income which represents net revenue less cost of sales and allocated selling,
general and administrative expenses. Intersegment net revenue and transfers are
recorded at OSCA's cost, and therefore there is no intercompany income or loss
recorded.

11. CONTINGENCIES

         OSCA is partially self-insured for employee health insurance claims and
generally incurs a maximum of $80,000 per employee under medical claims. While
OSCA has workers compensation and automobile liability insurance coverage, both
policies have a deductible of $250,000 per incident. Although OSCA believes that
adequate reserves have been provided for expected liabilities arising from its
insurance obligations, management's estimates of these liabilities may change in
the future as circumstances warrant.

         OSCA may be subject to various legal proceedings, claims and litigation
arising from a variety of matters including governmental regulations,
environmental matters, commercial matters, product liability, personal injury,
workers' compensation claims and other matters arising out of the ordinary
course of its business. In general, while the effect on future financial results
is not subject to reasonable estimation because considerable uncertainty exists,
in the opinion of management, the resolution of these legal proceedings and
claims will not have a material adverse effect on OSCA's financial position,
liquidity or results of operations.

12. NEW ACCOUNTING STANDARDS

         In August 2001, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 144, Accounting for the
Impairment or Disposal of Long-Lived Assets (SFAS 144). SFAS 144 addresses
financial accounting and reporting for the impairment or disposal of long-lived
assets. SFAS 144 supersedes SFAS No. 121, Accounting for Impairment of
Long-Lived Assets to be Disposed Of, and the accounting and reporting provisions
of APB Opinion No. 30, Reporting the Results of Operations for a disposal of a
segment of a business. SFAS 144 is effective for fiscal years beginning after
December 15, 2001. OSCA's adoption of SFAS 144 has not had a material impact on
its financial position and results of operations.

RESULTS OF OPERATIONS

         OSCA is organized into three global business segments:

                  -        Completion Fluids,

                  -        Completion Services and

                  -        Downhole Completion Tools.

         The segments are organized to offer a distinct but synergistic group of
products, technology and services.

         The Completion Fluids segment sells and recycles clear completion
fluids and performs related fluid maintenance services, such as filtration and
reclamation. OSCA also provides a broad line of specially formulated and
customized completion fluids. Completion fluids are used to control well

                                       12

pressure, clean the well subsequent to drilling activities and facilitate other
completion activities, while minimizing reservoir damage

     The  Completion Services segment provides:

         -        sand control pressure pumping,

         -        marine well services and

         -        coiled tubing services to perform gravel packing, frac packing
                  and well stimulation.

         The purpose of sand control pressure pumping is to force fluids and
gravel pack sand into the well to act as a downhole filter to inhibit the flow
of sand into the well. Coiled tubing is utilized to convey chemicals that
stimulate the well or deliver downhole equipment during well completion, or
during the production phase in order to stimulate well production rates.
Completion services are provided either by portable equipment placed directly on
a well, rig or platform or delivered via a fleet of advanced marine vessels.

         The Downhole Completion Tools segment designs, builds and installs
downhole completion tools for wells that are primarily used to control the
migration of reservoir sand into the well. The downhole completion tools help to
prevent the deterioration of the reservoir.

                                           ========         ========


         Market conditions for the three months ended March 31, 2002 have
deteriorated from the conditions that existed for the three months ended March
31, 2001. The deterioration was a result of a weakened economy and decreased oil
and natural gas prices. Those market conditions resulted in a decrease in
revenue for the Completion Fluids and Downhole Completion Tools segments for the
comparable three-month periods ended March 31, 2002 and 2001. The Completion
Services segment realized a net increase in revenue in spite of the market
conditions for the quarter ended March 31, 2002 compared to the quarter ended
March 31, 2001. The increase is attributable to approximately $1.0 million of
revenue generated in the first quarter of 2002 from OSCA's expansion into the
land market, with no comparable revenue in the first quarter of 2001.

                                           ========         ========


         The decrease in cost of goods sold and services for the Completion
Fluids and Downhole Completion Tools segments correlates with the decrease in
revenue. The increase in cost of goods sold and services in the Completion
Services segment relates to OSCA's land market expansion. OSCA incurred
approximately $2.2 million in costs of goods sold and services for the land
market during the quarter ended March 31, 2002, with no comparable cost in the
same period of the prior year.

         Selling, General and Administrative. Selling, general and
administrative expense increased $0.8 million, or 15.3%, to $6.2 million for the
three months ended March 31, 2002 compared to $5.4 million for the three months
ended March 31, 2001. The increase is primarily attributable to the following
factors:

- -        $325,000 in additional wage expense primarily attributed to OSCA's
         continued focus on the Downhole Completion Tools segment and OSCA's
         expansion into the land market in the Completion Services segment,

- -        $316,000 for bonus accruals for OSCA's workforce in response to
         anticipated achievement of performance targets as of March 31, 2002,
         whereas OSCA did not anticipate a need for bonus accruals at March 31,
         2001, and

- -        $146,000 increase in bad debt expense as a result of market conditions.

         Litigation Verdict. On April 4, 2002, a jury reached a verdict in the
lawsuit against OSCA and other defendants relating to a blowout of a well in the
Gulf of Mexico for which OSCA and others were engaged to perform workover
operations. Plaintiffs claimed that OSCA and the other defendants breached their
contracts to perform workover operations and were negligent in performing those
operations. The jury found OSCA and the other defendants responsible for those
claims and found OSCA's share of the damages to be approximately $13.3 million.
Those damages along with legal fees incurred in the first quarter of 2002 have
been charged to the litigation verdict expense.

         In connection with the lawsuit, OSCA asserted claims against its
insurers and insurance brokers in support of insurance coverage for this
incident. OSCA's insurers have denied coverage for this incident and a related
trial on these insurance coverage claims is scheduled to begin on May 20, 2002.

         Amortization of Intangibles. Amortization of intangibles for the
quarter ended March 31, 2001, included approximately $69,000 related to the
amortization of goodwill and with the adoption of SFAS 141, OSCA did not record
any amortization related to goodwill for the quarter ended March 31, 2002.

                                       14

The increase in amortization expense between periods relates to the amortization
of covenants not to compete that were incurred with the Ancor acquisition.

         Operating Income (Loss). As a result of the foregoing, operating income
(loss) decreased $19.6 million to a loss of $13.8 million for the three months
ended March 31, 2002 compared to operating income of $5.8 million for the same
period of the prior year. Operating income (loss) by segment is as follows:

         Income Tax Provision. The income tax provision for the quarter ended
March 31, 2002 was a tax benefit of $5.0 million, resulting in an effective tax
rate of 34.7%, while in 2001 OSCA recorded a tax expense of $1.7 million,
resulting in an effective tax rate of 38.0%. The decrease in effective rate was
primarily due to the fact that no benefit was recognized on certain losses
generated in international countries for the three months ended March 31, 2002.

         Net Income (Loss). Net income (loss) for the three months ended March
31, 2002 decreased $12.2 million to a net loss of $9.4 million from a net profit
of $2.8 million for the three months ended March 31, 2001 reflecting the factors
discussed above.

FINANCIAL CONDITION & LIQUIDITY

WORKING CAPITAL

     OSCA's primary uses for cash are:

         -        to fund working capital requirements,

         -        to make capital expenditures and

         -        for acquisitions.

     Historically, OSCA's cash sources have been provided by:

         -        operations,

         -        borrowings and

         -        prior to its IPO, intercompany borrowings from Great Lakes.


                                       15

         To the extent OSCA's future cash requirements exceed the cash provided
by operations, OSCA will fund those requirements through debt or equity
financing activities.

         OSCA's working capital at March 31, 2002 was $45.5 million compared to
$51.1 million at December 31, 2001. The decrease is attributable to the accrual
related to the Newfield litigation which is offset by the tax benefit associated
with the accrual.

         OSCA's operations used $0.7 million in cash for the first three months
of 2002 and provided $8.5 million in cash in the first three months of 2001. The
difference in operating cash flow is primarily attributable to OSCA's net income
(loss) for the respective periods. Capital expenditures for the three months
ended March 31, 2002 and 2001 were $7.0 million and $3.3 million, respectively.
During the first quarter of 2002, OSCA continued its planned capital
expenditures related to the expansion of its land based completion services
segment. In connection with that expansion, OSCA used $1.9 million to acquire
the assets of Ancor Services, Inc., a provider of land based well stimulation
products and services to oil and natural gas producers in East Texas and North
Louisiana. OSCA also deposited $7.2 million into a Rabbi Trust to cover some,
but not all of its obligations to senior management of OSCA should a change of
control occur pursuant to the pending merger with BJ Services Company. The
manager of the Rabbi Trust has invested the funds into a money market account.
If the merger does not occur the funds will become an unrestricted asset of
OSCA.

         OSCA's primary source of funds for the first quarter of 2002 was
available cash and additional net borrowings of $8.9 million from its $40.0
million credit facility. During the first quarter of 2001, OSCA's primary source
of funds was from operations and OSCA was able to reduce outstanding debt.

Long Term Debt Facilities

         At March 31, 2002, OSCA had available borrowings of $3.3 million under
its credit facility compared to $12.3 million at March 31, 2001. OSCA had one
outstanding letter or credit for $750,000 as of March 31, 2002 and 2001 which
reduced availability under its credit facility.

         As a result of the litigation verdict, which resulted in a $13.5
million expense, OSCA was in violation of covenants related to funded
indebtedness and fixed coverage ratios. On April 30, 2002, the lenders granted
OSCA a modification in the calculation of those two covenants which brought OSCA
into compliance.

Future Capital Needs

         Capital expenditures for the year ended December 31, 2002 are expected
to be approximately $19.1 million with $7.0 million already spent in the first
quarter of 2002. The remaining capital expenditures are expected to be funded
from operations or additional borrowings.

         While a verdict of $13.3 million has been awarded against OSCA as a
result of the Newfield litigation, management is under the opinion that a
significant portion of the verdict will be covered by insurance. OSCA's insurers
have denied coverage and a trial to determine the extent of the insurance
companies' liability is scheduled to start May 20, 2002. There can be no
assurance as to the result of that trial.

RECENT ACCOUNTING PRONOUNCEMENTS

         In June 2001, the Financial Accounting Standards Board issued
Statements of Financial Accounting Standards No. 141, Business Combinations, and
No. 142, Goodwill and Other Intangible Assets, effective for fiscal years
beginning after December 15, 2001. Under the new rules, goodwill (and intangible
assets deemed to have indefinite lives) will no longer be amortized but will be
subject to annual impairment tests in accordance with the Statement. Other
intangible assets will continue to be amortized over their useful lives. OSCA
adopted the new rules on accounting for goodwill and other intangible assets
effective January 1, 2002. OSCA has not yet performed its transitional
impairment tests in conjunction with the adoption of SFAS 142.

         In August 2001, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 144, Accounting for the
Impairment or Disposal of Long-Lived Assets. SFAS 144 addresses financial
accounting and reporting for the impairment or disposal of long-lived assets and
supersedes SFAS No. 121, Accounting for the Impairment of Long-Lived Assets to
be Disposed Of, and the accounting and reporting provisions of APB Opinion No.
30, Reporting the Results of Operations for a disposal of a segment of a
business. SFAS 144 is effective for fiscal years beginning after December 15,
2001. OSCA's adoption of SFAS 144 has not had a material impact on its financial
position and results of operations.

FORWARD-LOOKING STATEMENTS

         This report contains forward-looking statements involving risks and
uncertainties that affect OSCA's operations as discussed in the 2001 Annual
Report on Form 10-K filed with the SEC. Accordingly, there is no assurance that
OSCA's expectations will be realized.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

         OSCA's exposure to market risk for changes in interest rate and its
exposure to foreign exchange risk has not changed materially since December 31,
2001.

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

         On September 18, 2000, OSCA was served with notice that a lawsuit was
filed against it and other named defendants on September 1, 2000 in the District
Court of Harris County, Texas. The action is brought by certain underwriting
syndicates of Lloyd's of London who claim to be subrogated to the claim of their
insureds, Newfield Exploration Company, Apache Oil Corporation, Continental Land
& Fur, and Fidelity Oil ("Plaintiffs"). The other defendants include High
Pressure Integrity, Inc. and Chalmers, Collins & Alwell, Inc. On September 8,
2000, OSCA filed a lawsuit against the Plaintiffs and the other defendants in
the United States District Court, Western District of Louisiana,
Lafayette-Opelousas Division. Other actions have also been filed in connection
with the same circumstances. All actions have now been consolidated into one
proceeding in the United States District Court, Southern District of Texas.

         The lawsuits relate to a blowout of a well situated in the Gulf of
Mexico, offshore Louisiana, for which OSCA and others were engaged to perform
specific workover operations. In the Texas case,

                                       17

Plaintiffs seek damages, interest and other costs in the approximate amount of
$21.5 million, alleging that OSCA and the other defendants breached their
contracts to perform workover operations, and were negligent in performing those
operations. OSCA alleges negligence against the Plaintiffs and other defendants
and seeks damages, interest, costs and general and equitable relief. OSCA filed
a third party demand against its underwriters and insurance broker in support of
coverage of claims asserted against OSCA in the Newfield matter.

         On April 4, 2002, a Federal Court jury in Houston, Texas reached a
verdict in the lawsuit against OSCA and other defendants. The jury found OSCA
and the other defendants responsible for those claims and found OSCA's share of
the damages to be approximately $13.3 million. A charge of $13.5 million has
been recorded in the first quarter of 2002, which includes $0.2 million of legal
fees incurred during the quarter.

         In connection with the lawsuit, OSCA asserted claims against its
insurers and insurance brokers in support of insurance coverage for this
incident. OSCA's insurers have denied coverage for this incident and a related
trial on these insurance coverage claims is scheduled to begin on May 20, 2002.
The court has not yet entered a final judgment on the liability claim and OSCA
does not expect final judgment to be entered until completion of the related
insurance trial.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         On February 20, 2002, OSCA announced that it entered into a definitive
merger agreement with BJ Services Company. Under the terms of the agreement, BJ
Services will acquire all of the outstanding shares of OSCA for $28.00 per share
in cash. A special committee of independent members of OSCA's Board reviewed the
transaction on behalf of the public stockholders and recommended the transaction
to the complete OSCA Board, which then unanimously approved the merger
agreement. The transaction has a total equity value of approximately $420.0
million.

         Great Lakes Chemical Corporation, which owns approximately 53% of
OSCA's outstanding Common Stock and holds approximately 92% of the voting power,
has delivered its written stockholder consent approving the transaction with BJ
Services. The Great Lakes consent constitutes sufficient action by OSCA
stockholders to approve the transaction.

         The transaction is subject to regulatory approvals and OSCA has
received those approvals including those under the Hart-Scott-Rodino Antitrust
Improvements Act. OSCA has filed an information statement describing the
transaction with the Securities and Exchange Commission mailed such statement to
OSCA stockholders on May 2, 2002. OSCA anticipates the merger closing on May 31,
2002. There can be no assurance that the merger will be consummated in
accordance with the terms of the merger agreement, if at all.
