RESEARCH TRIANGLE PARK, N.C. - July 18, 2001 - Quintiles Transnational Corp.
(Nasdaq: QTRN) today announced financial results for second quarter 2001. Net
income for the quarter ended June 30, 2001, was $9.7 million compared to a loss

quarter 2000 diluted earnings per share were $3.76. Net revenue for the second
quarter 2001 was $404.3 million compared to $423.1 million for second quarter
2000.

On a sequential quarterly basis, second quarter 2001 net income of $9.7 million
and EPS of $0.08 compared to net income of $7.8 million and EPS of $0.06 for
first quarter 2001. Second quarter 2001 net revenue of $404.3 million compared
to $404.5 million for first quarter 2001.

Net new business in the first half of 2001 was $904 million, a 37% increase
compared with the six-month period ending Dec. 31, 2000, and a 23% increase from
the first half of 2000, resulting in a backlog at June 30, 2001, of $1.9
billion.

"We're pleased to have recorded our fifth consecutive quarter of increasing
operating margins and net income from continuing operations, and to have
exceeded analysts' consensus expectations for EPS. Our new business signings
during the first half were strong," said Quintiles Chief Executive Officer Pam
Kirby, Ph.D.

"I'm particularly pleased by the financial performance of our Product
Development group, which achieved record quarterly revenue of $224.6 million. In
that group, in addition to revenue growth, we're seeing improved margins because
of increased efficiencies and better structuring of contracts. We continue to
focus on building strategic relationships with our customers, as illustrated by
today's announcement of a five-year agreement with Solvay Pharmaceuticals, which
calls for Quintiles to provide at least 40% of Solvay's outsourced projects in
the first year and at least 50% in the four years to follow. Our global
resources, therapeutic expertise and high-quality execution have made Quintiles
the industry leader in delivering these types of creative corporate solutions
for our customers."

Quintiles Chairman Dennis Gillings, Ph.D., said: "Our corporate ventures group,
PharmaBio Development, had a very active second quarter in signing seven
agreements to help our customers develop or commercialize their products.
PharmaBio financing was key in reaching agreements with ArgoMed and Pilot
Therapeutics to help commercialize their products to treat prostate disease and
asthma, respectively, and in our preferred provider alliance with Innapharma to
develop its treatments for central nervous system disorders.

"Our strategic alliance with Care Capital, the life-sciences investment fund
founded by former SmithKline Beecham CEO Jan Leschly, already has yielded
results, and I'm excited by the capabilities this alliance offers pharma and
biotech companies."
