         (a) PENSION PLAN. Executive shall be entitled to participate in any

that in no event after the adoption of such plan by the Company will Executive
receive lesser benefits under such plan than are provided to Executive (and his
spouse) in this Section 8. In the absence of such pension plan, or in the event
that any such pension plan provides for lesser benefits than are provided in
this Section 8, the Company shall pay to Executive, commencing on the date that
he retires from employment with the Company, retirement payments (including
payments under any such pension plan) of not less than $400,000 per year, which
amount shall be subject to annual cost of living increases of 3% per year
beginning 2003 (the "Retirement Payments").

         (b) INSURANCE. The Company shall continue to provide to Executive the
health and life insurance benefits that the Company is required to provide under
Section 5(c) of this Agreement.

         (c) SPOUSAL BENEFIT. For so long as Executive's spouse shall survive

benefits that were made available to her under the Executive's health insurance
coverage.

9. DEATH. In the event of Executive's death, the Company shall pay to Executive
(or his spouse, heirs or personal representatives as appropriate) the Base
Compensation then owing to Executive, the pro rata amount of the Bonus
Compensation payable to Executive for such year, and, if Executive is survived
by his spouse, the on-going spousal benefits payable to Executive's Spouse under
Section 8(c).

10. CONFIDENTIAL INFORMATION AND INTELLECTUAL PROPERTY. Executive agrees that he
shall continue to be bound by the confidentiality and intellectual property
agreement that he has entered into with the Company.

11. NON-COMPETITION. For so long as Executive is receiving payments from the
Company under this Agreement, Executive covenants and agrees that he will not,
directly or indirectly, whether as principal, agent, trustee or through the
agency of any corporation, partnership, association or agent (other than as the
holder of not more than 10% of the total outstanding stock of any company the
securities of which are traded on a regular basis on recognized securities
exchanges) (i) work for (in any capacity, including without limitation director,
officer or employee) any other business or pharmaceutical company that competes
with the Company, or (ii) recruit, or otherwise influence or attempt to induce
employees of the Company to leave the employment of the Company. Executive
acknowledges that his services to be rendered hereunder are of a special and
unusual character that have a unique value to the Company and the conduct of its
business, the loss of which cannot adequately be compensated by damages in an
action at law.

         Executive has carefully read and considered the provisions of this
Section 11 and agrees that the restrictions set forth in such sections are fair
and reasonable and are reasonably required for the protection of the interests
of the Company, its officers, directors, shareholders, and other employees, for
the protection of the business of the Company. Executive acknowledges that he is
qualified to engage in businesses other than those that are subject to this
Section 11. It is the belief of the parties, therefore, that the best protection



                                       3
<PAGE>

that can be given to the Company that does not in any way infringe upon the
rights of Executive to engage in any unrelated businesses is to provide for the
restrictions described above. In view of the substantial harm which would result
from a breach by Executive of Section 11, the parties agree that the
restrictions contained therein shall be enforced to the maximum extent permitted
by law. In the event that any of said restrictions shall be held unenforceable
by any court of competent jurisdiction, the parties hereto agree that it is
their desire that such court shall substitute a reasonable judicially
enforceable limitation in place of any limitation deemed unenforceable and that
as so modified, the covenant shall be as fully enforceable as if it had been set
forth herein by the parties.

12. REMEDIES. The provisions of Section 11 of this Agreement shall survive the
termination of this Agreement as set forth therein, regardless of the
circumstances or reasons for such termination, and inure to the benefit of the
Company. The restrictions set forth in Sections Section 11 are considered to be
reasonable for the purposes of protecting the business of the Company. The
Company and Executive acknowledge that the Company would be irreparably harmed
and that monetary damages would not provide an adequate remedy to the Company if
the covenants contained in Section 11 were not complied with in accordance with
their terms. Accordingly, Executive agrees that the Company shall be entitled to
injunctive and other equitable relief to secure the enforcement of these
provisions, in addition to any other remedy which may be available to the
Company, and that the Company shall be entitled to receive from Executive
reimbursement for reasonable attorneys' fees and expenses incurred by the
Company in enforcing these provisions.

13. NOTICES. Any notice required or permitted to be given under this Agreement
shall be sufficient if in writing and if sent by registered mail to the
addresses below or to such other address as either party shall designate by
written notice to the other:

Agreement supersedes any prior statements, writings, promises, understandings or

15. ASSIGNMENT. The rights and obligations of the Company under this Agreement
shall inure to the benefit of and shall be binding upon the successors and
assigns of the Company. The Executive may not assign his rights and obligations
under this Agreement.

16. FULL SETTLEMENT. The Executive shall not be obligated to seek other
employment by way of mitigation of the amounts payable to the Executive under
any of the provisions of this Agreement. The amounts payable to Executive under
this Agreement shall not be reduced by any compensation payable to Executive
from employment by another employer after the date of Executive's termination
provided such employment does not violate the terms of Section 11 hereof. The
Company agrees to pay all legal fees and expenses which the Executive may
reasonably incur as a result of any contest by the Executive or the Company or
others of the validity or enforceability of, or liability under any provision of
this Agreement or any guarantee of performance thereof, in each case plus
interest, provided that the Executive is the prevailing party in any such
contest. If the Executive is not the prevailing party each party shall pay its
own legal fees and expenses except that if such contest is the result of a
claimed breach of Section 11, and the Company shall be the prevailing party, the
Executive shall pay the reasonable legal fees and expenses of the Company. The
determination of the prevailing party in any contest shall be made by the
tribunal which shall resolve such contest, or by the parties if such contest is
settled without resort to any such tribunal.

17. MISCELLANEOUS.

         (a) This agreement shall be subject to and governed by the laws of the
State of Florida, without regard to the conflicts of laws principles thereof.

         (b) The section headings contained herein are for reference purposes
only and shall not in any way affect the meaning or the interpretation of this
Agreement.

         (c) The failure of any party to enforce any provision of this Agreement
shall in no manner affect the right to enforce the same, and the waiver by any
party of any breach of any provision of this Agreement shall not be construed to
be a waiver by such party of any succeeding breach of such provision or a waiver
by such party of any breach of any other provision.

         (d) All written notices required in this Agreement shall be sent
postage prepaid by certified or registered mail, return receipt requested.

         (e) In the event any one or more of the provisions of this Agreement
shall for any reason be held invalid, illegal or unenforceable, the remaining
provisions of this Agreement shall be unimpaired, and the invalid, illegal or
unenforceable provision shall be replaced by a mutually acceptable valid, and
enforceable provision which comes closest to the intent of the parties.

         (f) This Agreement may be executed in any number of counterparts, each
of which shall constitute an original and all of which together shall constitute
one and the same instrument.
