               COVALENT REPORTS RESULTS FOR FIRST QUARTER 2005

    WAYNE, Pa., May 16 /PRNewswire-FirstCall/ -- Covalent Group, Inc.
(Nasdaq: CVGR) today announced its financial results for the first quarter
ended March 31, 2005.  These results were generally in line with our
previously stated expectations for the quarter.

    Net revenue for the first quarter of 2005 was $3.2 million, a decrease of
$2.1 million as compared with the comparable prior year period. This change was
the result of lower clinical trial activity during the first quarter of 2005
compared with the first quarter of 2004. Our first quarter 2005 net revenues
grew sequentially by 21% compared with the fourth quarter of 2004 continuing a
positive revenue trend which began in the fourth quarter of 2004.

    Net expenses for the quarter ended March 31, 2005, excluding the
reimbursement for out of pocket expenses, were $3.3 million versus $5.3 million
for the comparable prior year period, a decrease by approximately $2.0 million.
This decrease was principally due to the combination of reduced direct expenses
relating to a lower level of clinical trial activity and reduced selling,
general and administrative expenses (SG&A) due principally to headcount
reductions.

    Net loss for the first quarter of 2005 was $98 thousand or ($.01) per share
compared to net income of $27 thousand or $0.00 (breakeven) per share for the
comparable prior year period.

    Cash and cash equivalents were $5.2 million as of March 31, 2005 compared
with $3.2 million as of December 31, 2004, an increase of $2.0 million. This
increase resulted from cash provided from operating activities in the amount of
$2.1 million.

    Our backlog was approximately $14 million as of March 31, 2005 compared to
approximately $11 million as of March 31, 2004.

    Kenneth M. Borow, M.D., President and Chief Executive Officer commented,
"Our first quarter financial results improved significantly compared to the last
three quarters of 2004. We are especially pleased with the continued growth of
our cash position and our strengthening balance sheet. As of March 31, 2005,
compared to one year ago, our cash and cash equivalents have increased by $2.0
million while our backlog is up by $3 million."

    Dr. Borow continued, "As we move forward as a company, we believe that
Covalent will continue to build upon its recent programmatic successes. We are
confident that the financial issues relating to the completion of our legacy
clinical trials that impacted negatively on our 2004 financial results are now
behind us. Our results going forward will be based on the current book of
business and backlog which is on much more favorable terms than the legacy
studies. As such, I expect that 2005 will be a stronger year for the Company
than was 2004. I believe that Covalent is very competitive for numerous new
business opportunities that could significantly increase the amount of our 2005
new business awards. The anticipated result of our new business awards, our
leaner cost structure, potential increases in backlog and more favorable mix of
existing contracts should continue to reverse the trends that affected our
financial performance in 2004."



    Dr. Borow concluded, "We recognize the need to strengthen our company with
additional resources to resume and sustain growth. We are continuing to
evaluate, as we have done in the past, potential growth strategies including
organic growth as well as mergers and acquisitions with other companies. We
believe that it is important for us to have a broader global 'footprint,'
especially in Central and Eastern Europe, in order to help convert business
development opportunities into signed contracts. We believe that offering our
current and prospective clients the combination of our proven programmatic
development capabilities and a more robust global infrastructure will result in
increased company growth and improved shareholder value. We are committed to our
strategic goals and look forward to a significant improvement in operating
results for the remainder of 2005."
