              Re:  Separation from Employment with eXegenics, Inc.

Dear Dr. Bollon:


     The purpose of this letter agreement (the "Agreement") is to set forth the
terms of your separation from employment with eXegenics, Inc. (the "Company").
Payment of the Separation Pay and Benefits described below is contingent on your
agreement to and compliance with the terms and conditions of this Agreement, as
set forth below.

     1.   SEPARATION OF EMPLOYMENT. Your separation of employment with the
          Company is effective January 10, 2003 (the "Separation Date"). You
          acknowledge that from and after the Separation Date, you shall have no
          authority to, and shall not, represent yourself as an employee or
          agent of the Company.

     2.   SEPARATION PAY, BENEFITS AND STOCK OPTIONS. In exchange for the mutual
          promises set forth in this Agreement, and following your execution of
          this Agreement, the Company agrees to provide you with the following
          Separation Pay and Benefits:


          (a)  The Company shall provide you with a lump sum payment of
               $268,000, which includes payment of your current salary and car
               allowance at your regular rate of pay through November 30, 2003.
               This payment, less applicable taxes and withholdings (the
               "Separation Pay") will be paid to you by January 14, 2003.


          (b)  You shall be entitled to continuation of your participation in
               the Company's medical insurance coverage plan through November
               30, 2003, to the same extent that such coverage is extended to
               current Company employees, and on the same terms as such
               insurance coverage is presently extended to you. You will have
               the right, subject to all the requirements of COBRA, to continue
               your medical and dental insurance thereafter pursuant to the
               provisions of the Consolidated Omnibus Budget Reconciliation Act
               of 1985.

<PAGE>

         (c)  You shall receive payment for your accrued but untaken vacation
              days as of your Separation Date in the gross amount of $19.230,
              less applicable taxes and withholdings, which is payment in full
              for 20 days.

         (d)  The Company has agreed that all of your unvested options will
              vest as of your Separation Date, and the term of exercise for all
              such options will be extended to three years from your Separation
              Date, except for the options that will expire prior to December
              31, 2005 as a result of the 10-year exercise period limitation. A
              schedule of your outstanding options is attached hereto.

     You acknowledge and agree that the Separation Pay, Benefits and agreement
regarding options are not otherwise due or owing to you under any the Company
employment agreement (oral or written) or the Company policy or practice and
that the Company owes you no other wages, payments, money or benefits other
than specially provided for in this Agreement.

    3.   OTHER AGREEMENTS/SURVIVAL OF OTHER AGREEMENTS.

         (A)  You have agreed that, at the time you execute this Agreement, you
              shall resign as a member of the Board of Directors of the
              Company, effective December 31, 2002. You will submit such
              resignation in writing to the Board.

         (B)  The Company has agreed that you may utilize your office at the
              Company for a period of six months commencing on the Separation
              Date. You will have limited access to the Company computer
              network; thus, you will need to make arrangements for an Internet
              email address. You agree that you will not hold yourself out as
              affiliated with the Company during the time you have use of the
              Company office. Your use of the Company office is at your sole
              risk and liability and shall not be covered under the Company
              insurance policy in any respect.

         (C)  You expressly acknowledge and agree that all information relating
              in any way to this Agreement, including the terms and amount of
              financial consideration provided for in this Agreement, shall be
              held confidential by you and shall not be publicized or disclosed
              to any person (other than an immediate family member, legal
              counsel or financial advisor, provided that any such individual
              to whom disclosure is made agrees to be bound by these
              confidentiality obligations), business entity or government
              agency (except as mandated by state or federal law), except that
              nothing in this paragraph shall prohibit you from participating
              in an investigation with a state or federal agency if requested
              by the agency to do so.

          (D)  You further agree that you will not make any statements
               that are professionally or personally disparaging about, or
               adverse to, the interests of the Company (including its officers,
               directors, employees and consultants) including, but not limited
               to, any statements that disparage any person, product, service,
               finances, financial condition, capability or any other aspect of
               the business of the Company, and that you will not engage in any
               conduct which could reasonably be expected to harm professionally
               or personally the reputation of the Company (including its
               officers, directors, employees and consultants).

          (E)  It is the Company's policy to provide no information regarding
               its employees to third parties, and consistent with this policy,
               in the event the Company is contacted by a prospective employer,
               the Company will only provide information relating to your
               position, title, period of employment and salary.

          (F)  You and the Company acknowledge that your Employment Agreement
               with the Company dated March 1, 1992 is hereby terminated in all
               respects except that paragraphs 6, 7, and 8 shall survive in all
               respects. Notwithstanding the foregoing, the Company understands
               that you may make a proposal to the Company for the purchase of
               certain Company assets. The Company agrees that such a proposal
               shall not be deemed to violate any of your surviving obligations
               under the Employment Agreement.

     4.        YOUR RELEASE OF CLAIMS. You hereby agree and acknowledge that by
               signing this Agreement and accepting the Separation Pay and
               Benefits discussed in Section 2, and for other good and valuable
               consideration, you are waiving your right to assert any and all
               forms of legal Claims against the Company(1/) of any kind
               whatsoever, whether known or unknown, arising from the beginning
               of time through the date you execute this Agreement (the
               "Execution Date"). Your waiver and release herein is intended to
               bar any form of legal claim, charge, complaint or any other form
               of action (jointly referred to as "Claims") against the Company
               seeking any form of relief including, without limitation,
               equitable relief (whether declaratory, injunctive or otherwise),
               the recovery of any damages, or any other form of monetary
               recovery whatsoever (including, without limitation, back pay,
               front pay, compensatory damages, emotional distress damages,
               punitive damages, attorneys fees and any other costs) against the
               Company, for any alleged action, inaction or circumstance
               existing or arising through the Execution Date.

               decide whether or not to enter into this Agreement. You further
               acknowledge that you have had reasonable and sufficient time to

               calendar day is the "Effective Date"). You understand that if you
               wish to revoke this Agreement for any reason or for no reason at
               all, you may do so during the first seven (7) calendar days
               following your signing it by delivering written notice of such

               above, and the terms of any stock option agreements, this
               Agreement supersedes any and all prior or contemporaneous oral
               and/or written agreements between you and the Company, and sets
               forth the entire agreement between you and the Company. No
               variations or modifications hereof shall be deemed valid unless
               reduced to writing and signed by the parties hereto. The failure
               of the Company to seek enforcement of any provision of this
               Agreement in any instance or for any period of time shall not be
               construed as a waiver of such provision or of the Company's right
               to seek enforcement of such provision in the future. This
               Agreement shall be governed by and construed in accordance with
               the laws of Texas, without giving effect to conflict of law
               principles. You agree that any action, demand, claim or

          renounce in advance any right to a trial by jury in connection with
          such legal action. The provisions of this Agreement are severable, and
          if for any reason any part hereof shall be found to be unenforceable,
          the remaining provisions shall be enforced in full.


     By executing this Agreement, you are acknowledging that you have been
afforded sufficient time to understand the terms and effects of this Agreement,
that your agreements and obligations hereunder are made voluntarily, knowingly
and without duress, and that neither the Company nor its agents or
