                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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

NOTE 1:   BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements of OSCA, Inc. and
its consolidated subsidiaries ("OSCA") have been prepared in accordance with
generally accepted accounting principles 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 accruals) 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.

For further information, refer to the consolidated financial statements and
footnotes thereto, included in Form S-1.

NOTE 2:   SPECIAL CHARGES

During 1998, in connection with a Great Lakes repositioning plan, OSCA
recognized a special charge of $13.4 million or $8.3 million after income taxes.
Of the $13.4 million, $10.1 million was recorded for actions taken in the third
quarter of 1998 and another $2.6 million was recorded in the fourth quarter of
1998. In addition, in the fourth quarter of 1999, due to certain changes in the
repositioning plan, OSCA recognized a credit to special charges in the amount of

RESULTS OF OPERATIONS

Revenues in the second quarter increased 22.5% to $28.9 million from $23.6
million compared to the corresponding period in 1999. Volume expansion
accompanied by moderate price increases in Completion Services and Downhole
Tools drove the increase. Pricing in Completion Fluids appeared to stabilize
during the period.

Costs of goods sold increased 6.1% to $20.9 million from $19.7 million, however
gross profit margin improved to 27.4% from 16.5% as compared to second quarter
1999 reflecting the effect of the increased volume, favorable product mix and
price improvement.

Selling, general and administrative expenses increased to $5.4 million over the
prior year period of $5.1 million. This increase is primarily due to the
addition of technical personnel required to support increasing exploration and
production activity, particularly in the Gulf of Mexico.

<PAGE>   10
Operating income improved to $2.6 million for the reporting period as compared
to an operating loss of ($1.2) million last year. Net income was $1.7 million,
or $0.18 per share compared to a net loss of ($0.4) million or ($.04) per share
one year ago.

For the first six months, revenues increased 19% to $55.4 million from $46.6
million one year ago. The increase was primarily due to rising well completion
activity in the Gulf of Mexico driven by high commodity prices for oil and gas.
Net income for the six months was $2.4 million, or $0.27 per share, as compared
to a net loss of ($0.3) million or ($.04) per share for the corresponding period
last year.

Interest and other income was $0.3 million, for the three months ended June 30,
2000 equivalent to that for the same period in 1999. Interest and other expense
increased $0.1 million for the three months ended June 30, 2000 from the same
period last year due to the $31.0 million interest bearing loan established in
June of 2000.

SEGMENT INFORMATION

Set forth below is a discussion of the operations of the Company's business
segments: Completion Fluids, Completion Services and Downhole Completion Tools.
Operating income, which is the income measure the company uses to evaluate
business segment performance, represents net sales less costs of products sold,
selling, general and administrative expenses.

COMPLETION FLUIDS BUSINESS UNIT

The Completion Fluids business unit is a market leader in the sale and service
of high-density brine completion fluids and related onsite fluid maintenance
services including filtration, engineering and performance additives. Results
for the quarter and first six months follows:

                                 THREE MONTHS ENDED          SIX MONTHS ENDED
                                       JUNE 30                   JUNE 30
                                --------------------      ----------------------
                                   2000      1999           2000         1999
                                ---------  ---------      ---------    ---------
        Net revenues              $11.6       $13.6         $24.7        $27.1
        Operating income          $ 1.2       $ 0.3         $ 1.6        $ 1.7

Completion Fluids revenue for the quarter decreased 14.9% to $11.6 million
compared to $13.6 million one year ago, reflecting lower selling prices and
curtailed activity from two of the Company's contract customers. However,
operating income increased 300% to $1.2 million from $0.3 million due to
improved product mix led by sales of high-value proprietary fluid systems.

For the six months ended in June, Revenues decreased 8.8% to $24.7 million from
$27.1 million a year ago. As in the reporting quarter, this reflects lower
selling prices for conventional fluid systems. Operating income was down 5.8% to
$1.6 million compared to $1.7 million last year.

Completion Fluids has been operating under intense pricing pressure resulting in
price erosion of 10% since the second quarter of 1999. Prices appeared to
stabilize during the quarter. At the same time OSCA's focus on high demand
completions and proprietary products contributed to an operating margin

<PAGE>   11
improvement of 8% over the corresponding quarter in 1999. This is particularly
noteworthy in view of the price decline in the market.

COMPLETION SERVICES

The Completion Services business unit consists of the Marine Well Service, Skid
Pumping Service and Coiled Tubing Service product lines. Results for the quarter
and first six months follows:

                                   THREE MONTHS              SIX MONTHS
                                  ENDED JUNE 30            ENDED JUNE 30

                              ----------  ---------    ---------   ----------
        Net revenues            $ 9.2        $5.3        $17.7       $11.7
        Operating income        $ 0.0       ($1.1)       $ 1.1       $(1.1)

Completion Services revenue increased 73.6% versus the second quarter 1999.
Revenues for the first six months increased 51.3% compared to the same period
last year. Second quarter 2000 operating income improved $1.1 million (100%)
from second quarter 1999 and $2.2 million (200.0%) for the first six months.

New contracts in Brazil, market penetration and higher activity levels combined
to drive the improvements in revenue. The increased volumes coupled with higher
selling prices are responsible for the significant improvement in operating
income during the quarter and for the first six months.

DOWNHOLE COMPLETION TOOLS

The Downhole Completion Tools business unit provides downhole sand control tools
and production packers/accessories. Results for the quarter and first six months
follows:

                                   THREE MONTHS              SIX MONTHS
                                  ENDED JUNE 30            ENDED JUNE 30

                              ----------  ---------    ---------   ----------
        Net revenues            $ 8.1        $4.7        $13.0       $ 7.8
        Operating income        $ 2.0        $0.3        $ 2.2       $ 0.3

Completion Tools revenues increased 72.3% from second quarter of 1999. Revenues
in the first six months increased 66.7% compared to the corresponding period in
1999. Second quarter 2000 operating income improved $1.3 million (566.7%) from
second quarter 1999 and $1.9 million (633.3%) for the first six months.

<PAGE>   12
The significant improvement in revenue and operating income reflects gains in
market share and increased well completion activities. OSCA's expanding
intelligent well completion technology has positioned this business unit as the
front runner in high demand well completions.

FINANCIAL CONDITION & LIQUIDITY

Inventories were $22.4 million at June 30, 2000, an increase of $3.1 million
from year- end and $1.7 million from a year ago. The increase in inventories are
due to higher activity levels in the Downhole Completion Tool business.

Accounts receivable increased $4.4 million to $25.2 million at June 30, 2000, as
compared to December 31, 1999. The increase was due entirely to increases in
revenue as days sales outstanding decreased by 2 days over the prior period.

Current liabilities decreased $63.3 million to $13.4 million at June 30, 2000
from $76.7 million at December 31, 1999. The decrease was primarily attributable
to payment of the dividend note payable to Great Lakes. (See Note 7 to the
Consolidated Financial Statement.)

Long term debt increased to $31.3 million at June 30, 2000, as the company
established a line of credit with Bank One as part of the Initial Public
Offering of Class A common stock. (See Note 7 to the Consolidated Financial
Statement.)

Intercompany payables to Great Lakes decreased $41.1 million to $2.5 million at
June 30, 2000 from $43.6 million at year-end. Proceeds for this reduction came
primarily from the IPO proceeds and the line of credit established as part of
the Initial Public Offering. (See Note 7 to the Consolidated Financial
Statement.)

Capital spending for the first six months amounted to $2.0 million. Spending for
the year is expected to be approximately $4.0 million.

Additional paid in capital increased $78.6 million and common stock increased
$56,000 from year-end. The increase was due to the sale of 5,600,000 shares of
Class A common stock.
