Verdict Announced in Oil Well Blowout Lawsuit Against OSCA;
Related Trial on Insurance Coverage Scheduled to Begin May 20

OSCA Expects Merger with BJ Services to Close in May 2002

LAFAYETTE, Louisiana, April 9, 2002—OSCA, Inc. (Nasdaq: OSCA), today stated that on April 4th a Federal Court jury in Houston, Texas 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.

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

Commenting on the verdict, Robert Hollier, President and CEO of OSCA noted that "We are disappointed in this verdict and are actively evaluating our options, including the possibility of appeal." "In addition," Mr. Hollier added, "We expect to aggressively pursue our related claims for insurance coverage."

OSCA does not expect this verdict or the results of the insurance coverage trial to have any effect on its pending merger with BJ Services Company (NYSE: BJS; CBOE). Under the terms of the merger agreement, OSCA shareholders will receive $28.00 in cash per share in a merger with a subsidiary of BJ Services. Great Lakes Chemical Corporation, which owns approximately 53% of OSCA's common stock, has delivered its written stockholder consent approving the transaction. The Great Lakes consent constitutes sufficient action by OSCA stockholders to approve the transaction.

OSCA expects the pending merger with BJ Services to close in May 2002.
