Income from continuing operations per share on a diluted basis for first quarter 2003 was $0.21, which represents a 48% increase from first quarter 2002 income from continuing operations per share of $0.14. Income from continuing operations for first quarter 2003 was $25.2 million, a 46% increase compared to $17.3 million from a year ago. Total gross revenues and net revenues for first quarter 2003 were $512 million and $417 million, respectively, compared to $493 million and $398 million for first quarter 2002. Earnings per share for first quarter 2002 were $0.52, including $0.38 due to the cumulative effect of a change in an accounting principle.

"Improvements in quality and efficiency continue to produce success from our Product Development and Commercial Services groups," said Quintiles Chief Executive Officer Pam Kirby. "I was particularly pleased with the sequential and year-on-year revenue growth in our Product Development group."

Quintiles Transnational Chief Financial Officer Jim Bierman said: "Cash flow from operations for the first quarter was strong once again at $58 million. This is another indication of our continued focus on financial performance and was particularly attributable to our improved cash collection. A significant factor in our over achievement this quarter was our recognition of $18 million of investment gains which exceeded our investment gains for all of 2002."

On April 10, 2003, Quintiles Transnational and Pharma Services Holding, Inc. announced that they had signed a merger agreement for Quintiles' public shareholders to receive $14.50 per share in cash.

The transaction, which is anticipated to be completed later this year, is subject to Pharma Services' completion of its committed financing and customary conditions, including regulatory and Quintiles' shareholder approvals. Expenses related to the activities of the Special Committee were $1.7 million in first quarter 2003.
