or likely to injure the business of the Company); iii) Dr. Mollica's conviction
for any felony or for any other crime involving moral turpitude, whether or not

with a lawful written direction of the Board; or vi) any wanton and willful
dereliction of duties by Dr. Mollica. The existence of any of the foregoing

reasonable judgment.

                           d.       VOLUNTARY RESIGNATION. In the event that Dr.
Mollica shall voluntarily resign as Chief Executive Officer:

                                    (1)      Dr. Mollica shall provide the
                                             Company's Board of Directors with
                                             ninety (90) days' advance written
                                             notice of his intention to resign

                                    (2)      Following the effective date of his
                                             resignation, the Company shall be
                                             relieved of all other obligations
                                             to pay compensation to Dr. Mollica,
                                             except that the Company shall
                                             immediately pay Dr. Mollica all
                                             accrued, but unpaid, Base Salary
                                             and any other unpaid expenses or
                                             expense reimbursement. Dr. Mollica
                                             shall be entitled to receive a pro
                                             rata Incentive Bonus for the

                                             resignation becomes effective.

                           e.       DISABILITY. If Dr. Mollica becomes disabled
for more than one hundred eighty (180) days in any twelve (12) month period, the
Company shall have the right to terminate his employment without further
liability upon written notice to Dr. Mollica. Dr. Mollica shall be deemed
disabled for purposes of this Agreement either (i) if he is deemed disabled for
purposes of any long-term disability insurance policy paid for by the Company
and at the time in effect, or (ii) if in the exercise of the Company's
reasonable judgment, due to accident, mental or physical illness, or any other
reason, he cannot perform his duties as Chief


Executive Officer. In the event the Company shall terminate Dr. Mollica due to
disability, as described above, Dr. Mollica shall be entitled to receive the
benefits set forth in Section 4(a), reduced by the amount of any disability plan
or insurance benefit paid to him.

                           f.       DEATH. In the event of the death of Dr.
                                    Mollica, this Agreement shall automatically

cease as of the date of his death.

                           g.       CERTAIN ADDITIONAL PAYMENTS. If any of the
benefits or payments under this Agreement, or under any other agreement with or
plan of the Company (in the aggregate, the "Total Payments"), will be subject to
the tax (the "Excise Tax") imposed by Section 4999 of the Internal Revenue Code,
the Company shall pay Dr. Mollica in cash an additional amount (the "Gross-Up
Payment") such that the net amount retained by Dr. Mollica after deduction of
any Excise Tax upon the Total Payments and any federal, state and local income
tax and Excise Tax upon the Gross-Up Payment provided for by this Section 4(g)
shall be equal to the Total Payments. Such payments shall be made by the Company
to Dr. Mollica as soon as practical following a determination that any of the
Total Payments will be subject to the Excise Tax, but in no event beyond thirty
(30) days from such date.

                           All determinations required to be made under this
Section 4(g), including whether any of the Total Payments will be subject to the
Excise Tax and the amounts of such Excise Tax, shall be made by a nationally
recognized accounting firm (the "Accounting Firm") mutually acceptable to the
parties. The Accounting Firm shall provide detailed supporting calculations both
to the Company and to Dr. Mollica within 10 days after a request for such
determinations are made by Dr. Mollica or the Company. Any such determination by
the Accounting Firm shall be binding upon the Company and Dr. Mollica. For
purposes of determining the amount of the Gross-Up Payment, Dr. Mollica shall be
deemed to pay Federal, state and local income taxes at the highest marginal
rates applicable to Dr. Mollica as of the date of the determination.

                  5.       BOARD MEMBERSHIP. As Chief Executive Officer, Dr.
Mollica shall at all times be nominated by the Board to serve on the Company's
Board of Directors, subject to election by the stockholders.

vacation each year, in accordance with the Company's standard vacation policy,
and to those holidays observed by the Company. As an essential employee of the
Company, Dr. Mollica shall schedule his vacation and holiday observances so as
not to interfere with the performance of his duties as Chief Executive Officer.

accident and long-term disability insurance as the Company shall make available
from time to time to its executive employees.

                  8.       SEPARATION BENEFITS INSURANCE. During the Term of
this Agreement and the period during which Dr. Mollica is receiving payments
under Section 4(a)(2), the Company


will reimburse Dr. Mollica for the cost of obtaining term life insurance in an
amount equal to two times his Base Compensation, subject to a maximum annual
reimbursement of Twenty Thousand Dollars ($20,000).

                  9.       PROFESSIONAL EXPENSES. Dr. Mollica will be reimbursed
in accordance with the Company's policy and procedure for the reasonable costs
of properly documented professional and business related travel expenses
required in the course of his employment. The Company will also pay for
appropriate professional dues and memberships, which must be approved in advance
by the Board.

                  10.      INDEMNIFICATION. The Company agrees to indemnify Dr.
Mollica to the fullest extent permitted by Delaware law, including mandatory
advancement of costs allowed by law.

                  11.      TAXES. Dr. Mollica will be responsible for the
payment of any tax liability incurred as a result of this Agreement. The Company
may withhold tax on any payments or benefits provided to his as required by law
or regulation.

                  12.      CONFIDENTIAL INFORMATION. Except as reasonably
necessary to perform his duties as Chief Executive Officer, Dr. Mollica agrees
not to reveal to any other person or entity or use for his own benefit any
confidential information of or about Company or its operations, both during and
after his employment under this Agreement, including without limitation
marketing plans, financial information, key personnel, employees' salaries and
benefits, customer lists, pricing and cost structures, operation methods and any
other information not available to the public, without Company's prior written

                  13.      NON-COMPETITION. Dr. Mollica shall not, during the
course of his employment with the Company or for a period of twenty-four (24)
months thereafter, directly or indirectly:

                           a.       Be employed by, engaged in or participate in
the ownership, management, operation or control of, or act in any advisory or
other capacity for, any Competing Entity which conducts its business within the
Territory (as the terms Competing Entity and Territory are hereinafter defined);
provided, however, that notwithstanding the foregoing, Dr. Mollica may make
solely passive investments in any Competing Entity the common stock of which is
"publicly held" and of which Dr. Mollica shall not own or control, directly or
indirectly, in the aggregate securities which constitute 5% or more of the
voting rights or equity ownership of such Competing Entity;

                           b.       solicit or divert any business or any
customer from the Company or assist any person, firm or corporation in doing so
or attempting to do so;

                           c.       cause or seek to cause any person, firm or

recommend to any other person that they employ or solicit for employment or
retention as an employee or consultant, any person who is an employee of, or
exclusive consultant to, the Company.

                  The Company's obligation to make payments pursuant to Section
4 above shall terminate in the event that, and at such time as, Dr. Mollica is
in breach of his obligation not to compete as set forth in this Section 13. For
purposes of this Section, the term "Competing Entity" shall mean any entity
which is presently or hereafter engaged in the business of providing to third
parties products or services for pre-clinical drug discovery or chemical
development which (i) include the outlicensing of small molecule libraries, the
undertaking of drug candidate screening, and/or related drug optimization
activities, (ii) utilize combinatorial chemistry or high-throughput screening
technologies in offering pre-clinical drug discovery services, (iii) engage in
the development, marketing or sale of software programs which use molecular
simulation or analysis to predict chemical or biological activities, or (iv)
engage in the development, marketing or sale of software programs that store,
manage or analyze chemical or biological information. The term "Territory" shall
mean North America, Europe and Japan. Notwithstanding anything in the above to
the contrary, Dr. Mollica may engage in the activities set forth in Section
13(a) hereof with the prior written consent of the Company, which consent shall
not be unreasonably withheld. In determining whether a specific activity by Dr.
Mollica for a Competing Entity shall be permitted, the Company will consider,
among other things, the nature and scope of (i) the duties to be performed by
Dr. Mollica, and (ii) the business activities of the Competing Entity at the
time of Dr. Mollica's proposed engagement by such entity.

                  Dr. Mollica acknowledges and agrees that the covenants set
forth in this Section are reasonable and necessary in all respects for the
protection of the Company's legitimate business interests (including without
limitation the Company's confidential, proprietary information and trade secrets
and client good-will, which represents a significant portion of the Company's
net worth and in which the Company has a property interest). Dr. Mollica
acknowledges and agrees that, in the event that he breaches any of the covenants
set forth in this Section, the Company shall be irreparably harmed and shall not
have an adequate remedy at law; and, therefore, in the event of such a breach,
the Company shall be entitled to injunctive relief, in addition to (and not
exclusive of) any other remedies (including monetary damages) to which the
Company may be entitled under law. If any covenant set forth in this Section 13
is deemed invalid or unenforceable for any reason, it is the Parties' intention
that such covenants be equitably reformed or modified to the extent necessary
(and only to such extent to) render it valid and enforceable in all respects. In
the event that the time period and geographic scope referenced above is deemed
unreasonable, overbroad, or otherwise invalid, it is the Parties' intention that
the enforcing court shall reduce or modify the time period and/or geographic
scope to the extent necessary (and only to such extent necessary) to render such
covenants reasonable, valid, and enforceable in all respects.

                  14.      ARBITRATION. Any and all disputes between the parties
