         EXEGENICS AND INNOVATIVE DRUG DELIVERY SYSTEMS (IDDS) TO MERGE
      COMBINED ENTITY WILL HAVE THREE PRODUCTS ENTERING LATE-STAGE CLINICAL
             TESTING FOR THE MANAGEMENT OF MODERATE TO SEVERE PAIN


DALLAS, TX, NEW YORK, NY, SEPTEMBER 20, 2002 -- eXegenics Inc. (NASDAQ: EXEG)
and privately held Innovative Drug Delivery Systems, Inc. (IDDS) today announced
that the two companies have signed a definitive merger agreement. Under the
terms of the agreement, the two companies will complete a stock-for-stock
exchange in which a fixed ratio of one share of IDDS common stock will be
exchanged for 3.132 shares of eXegenics common stock. Upon the closing of the
merger, eXegenics will issue 48,387,193 shares of common stock, and will issue
up to 11,705,999 additional shares of common stock upon the exercise of
outstanding IDDS options and warrants, in exchange for all of IDDS' outstanding
equity interests. The transaction is to be a tax-free reorganization. Mark C.
Rogers, M.D., currently Chairman and CEO of IDDS, will be named Executive
Chairman of the combined company and Dr. Ronald L. Goode, Ph.D., currently
eXegenics' President and CEO, will continue as President and CEO.

"The merger of eXegenics and IDDS allows us to fulfill our joint goal of moving
rapidly towards the commercialization of pharmaceuticals that address important
medical needs," commented Dr. Goode. "Following the merger, the combined entity
will have three lead drugs, two of which have completed Phase II clinical
studies, as well as a development platform that supports acquiring and advancing
additional products."

Dr. Goode continued, "Mark Rogers has put together an excellent team at IDDS
possessing the ability to advance products efficiently through the development
process. I am truly excited as I believe that the complementary assets and
capabilities brought together by this combination offer the potential of
increased value for shareholders of both companies."



Dr. Rogers commented, "The newly combined firm begins with a solid foundation of
innovation in pain management, where we have significant clinical and
developmental expertise. The products in hand are being investigated for
conditions that account for a $3.4 billion segment of the worldwide pain
management market. Each of these products provides a distinct delivery advantage
for patients in moderate to severe pain, and we have marketing and distribution
rights for these products worldwide. We are very excited by the potential of
these products and by the opportunity to grow the pipeline in new directions."

"Given Dr. Goode's accomplished pharmaceutical career, including his track
record of successfully executing the clinical development programs that led to
the approval of more than a dozen NDA applications, our products should advance
rapidly towards commercialization," added Dr. Rogers. "I look forward to working
with Ron and his team as we chart the next stages for the combined entity's
promising product portfolio."

PRODUCT PORTFOLIO

The combined entity's product portfolio will include three lead product
candidates for the treatment of pain that have demonstrated safety and
effectiveness in early- and mid-stage clinical trials. Each of these product
candidates is a uniquely formulated version of an FDA-approved compound and was
selected based on the belief that it offered significantly lower clinical,
regulatory and commercial risk profiles as compared to new chemical entities, in
addition to having a high market potential and strong patent protection.

The company's programs will initially focus on developing prescription drugs for
the treatment of a variety of acute and chronic moderate-to-severe pain
syndromes. Products in clinical development in the United States and Europe
include:
