               PAREXEL ANNOUNCES CANCELLATION OF SERVICE CONTRACTS

BOSTON, MA, MARCH 1, 2000 - PAREXEL International Corporation (Nasdaq: PRXL)
announced today that Novartis, a key client, has reduced the amount of work
currently outsourced to the PAREXEL Clinical Research Services (CRS) business
unit, due to Novartis' reprioritization of its research pipeline. As a result,
PAREXEL reported that CRS revenues would fall materially short of expectations
commencing in the third quarter ending March 31, 2000. The Company estimates
that total revenues for the third quarter will be reduced by approximately $1 to
$2 million, for the quarter ending June 30, 2000 by up to approximately $9
million, and for fiscal 2001 by up to approximately $40 to $45 million. Earnings
per share will be reduced by approximately $0.04 in the quarter ending March 31,
2000, approximately $0.09 in the quarter ending June 30, 2000, and approximately
$0.20 in fiscal 2001. A restructuring charge, which is currently being
quantified, will be taken in the quarter ending March 31, 2000 and will involve
a reduction of up to 400 - 500 positions. Additional details concerning the
restructuring will be made available at a later date.

Joerg Reinhardt, Ph.D., Global Head of Pharma Development for Novartis
commented, "PAREXEL is a key strategic outsourcing partner, with whom we have a
long-standing relationship. We are pleased with the quality of work that PAREXEL
has delivered on these projects to date, and are continuing to partner with the
Company on other projects now. We look forward to our ongoing relationship with
PAREXEL."

"Although we are disappointed by these cancellations, they do not affect the
nature of our long-standing and productive working relationship with Novartis,"
stated Josef von Rickenbach, Chairman and Chief Executive Officer of PAREXEL.
"While such cancellations have recently affected the entire Contract Research
industry, there remains a significant demand for clinical development services
and the expertise that PAREXEL offers. This demand is evident in the strong new
business activity and proposal volume we are seeing. I would like to assure you
that we will be working even more aggressively to generate new business to
mitigate the impact of these cancellations."

Mr. von Rickenbach added, "Among the benefits of our recently established Client
Research Unit (CRU) structure is our ability to respond rapidly and rationally
to change, and we will therefore act quickly to match operational capacity with
demand and make any necessary infrastructure adjustments. Moving forward, we
will continue to analyze the impact of this cancellation on our business, and
will take steps to maintain high service levels and improve the profitability
and efficiency of our operations."
