                COVALENT REPORTS RESULTS FOR SECOND QUARTER 2005

    WAYNE, Pa., Aug. 11 /PRNewswire-FirstCall/ -- Covalent Group, Inc.
(Nasdaq: CVGR) today announced financial results for its second quarter ended
June 30, 2005.

    Our financial, business, programmatic and strategic accomplishments for the
second quarter of 2005 included the following:

     *  Strong operating cash flow with cash and cash equivalents rising to $4.8
        million from $3.2 million at December 31, 2004;

     *  Highly liquid balance sheet with no debt and minimal exposure to capital
        lease commitments;

     *  New business contracts for $9.2 million resulting, in part, from our
        recent programmatic successes in high profile clinical trials where we
        played a significant role;

     *  Increase in backlog by 42% since March 31, 2005;

     *  Major clinical operations and consultant contributor to Merck's landmark
        "Shingle Prevention Study" which was published as a lead article in The
        New England Journal of Medicine;

     *  Continued growth in our new business pipeline. This reflects, in part,
        new business opportunities that have been enhanced by our recent
        accomplishments in the design and management of clinical trials and
        patient disease registries; and

     *  Continued progress on our strategic goal to grow our business through
        new strategic alliances including mergers and acquisitions.

    Net revenue for the second quarter of 2005, excluding reimbursement revenue,
was $2.3 million as compared with $3.8 million for the comparable prior year
period. The decrease of $1.5 million in net revenue reflects a decrease in the
value and number of clinical studies being managed by the Company during the
second quarter of 2005 compared with the second quarter of 2004. There were no
significant revenues recognized in our second quarter 2005 financial results
from the recently signed $9.2 million clinical study agreement. We expect to
begin generating significant revenues from activities related to the performance
of this clinical study in the third quarter of 2005.

    Net expenses for the quarter ended June 30, 2005, excluding the
reimbursement for out-of-pocket expenses, were $2.8 million versus $5.7 million
for the comparable prior year period, a decrease of approximately $2.9 million.
This decrease resulted principally from a $2.3 million reduction in direct
expenses associated with decreased personnel costs related to lower clinical
trial activity and a $600 thousand reduction in selling, general and
administrative ("SG&A") expenses due principally to reduced headcount, decreased
professional fees and a $400 thousand reduction in bad debt expense.



    Net revenue for the six months ended June 30, 2005, excluding reimbursement
revenue, was $5.5 million versus $9.1 million for the comparable prior year
period. The decrease of $3.6 million in net revenue reflects a decrease in the
value and number of clinical trial studies being managed by the Company during
the first six months of 2005 compared to the comparable prior year period. Net
expenses for the six months ended June 30, 2005, excluding the reimbursement for
out-of-pocket expenses, was $6.2 million versus $11 million for the comparable
prior year period, a decrease of $4.8 million. This decrease was principally the
result of a $3.9 million reduction in direct expenses due to decreased personnel
costs related to lower clinical trial activity and an $800 thousand reduction in
SG&A due principally to a $400 thousand decrease in bad debt expense combined
with ongoing cost control initiatives and a decline in personnel costs.

    Net loss for the second quarter of 2005 was $483 thousand, or ($0.04) per
share, compared to a net loss of $1.4 million, or ($0.11) per share, for the
comparable prior year period.

    Net loss for the six months ended June 30, 2005 was $582 thousand, or
($0.04) per share, compared to a net loss of $1.4 million, or ($0.11) per share,
for the comparable prior year period.

    Cash and cash equivalents were $4.8 million as of June 30, 2005 compared
with $3.2 million as of December 31, 2004, an increase of $1.6 million. This
increase resulted principally from cash provided from operating activities in
the amount of $1.7 million.

    The amount of announced new business contracts in the second quarter was
$9.2 million. This brought our year-to-date new business awards to $10.7
million. Our backlog was approximately $20 million as of June 30, 2005 compared
to approximately $15 million at December 31, 2004, an increase of $5 million.
Sequentially, our backlog grew from approximately $14 million at March 31, 2005,
an increase of $6 million, or 42%.

    Kenneth M. Borow, M.D., President and Chief Executive Officer, commented,
"Our second quarter financial results improved significantly compared to the
second quarter of 2004. Despite our operating losses, our business continues to
provide positive cash flow from operations. We had a very successful quarter
relative to new business signings. As a result, our backlog in the second
quarter grew by 42% compared to the value at the end of the first quarter of
2005. In addition, we are competing for multiple new business contracts that we
believe will help us to significantly improve our future operating results. We
are especially pleased that our programmatic successes in 2004 and 2005 have
positioned us to be highly competitive for new business awards that we are
currently seeking. We expect to make additional new business announcements
during the third quarter of this year."

    Dr. Borow continued, "As I have previously stated, we remain committed to
growing our revenue base through new business awards and new strategic alliances
including mergers and acquisitions. We continue to actively seek new business
opportunities in order to grow revenues and more fully leverage our in-house
resources thereby facilitating a return to profitability. Our actions in this
respect are ongoing, and our commitment to achieve our strategic objectives for
top and bottom-line growth is well underway. We expect to have more clarity on
the success of our efforts before the end of 2005. We are committed to our
strategic goals as well as increasing shareholder value, and we anticipate and
look forward to continuing improvements in backlog, operating results and
operating cash flows for the remainder of 2005."
