Company, the Executive shall be provided with disability insurance providing for
disability payments to the Executive following a termination of Executive's
employment hereunder as a result of Disability (as defined in Section 8.2

after the date hereof to its respective executives, on the same basis as shall
be available to such other executives without restriction or limitation by
reason of this Agreement; PROVIDED, HOWEVER, that Executive shall not
participate in two or more plans providing duplicative benefits or coverage. The
Company shall use its reasonable efforts to waive any qualifying period for
participation in any such plan by the Executive.

                  7.4 Nothing herein contained shall prevent the Company from at
any time increasing the compensation herein provided to be paid to Executive,
either permanently or for a limited period, or from paying bonuses and other
additional compensation to Executive, whether or not based upon the earnings of
the business of Company, or from increasing or expanding any


                                       -5-
<Page>

employee benefit program applicable to the Executive, in the event the Company,
in its sole discretion, shall deem it advisable so to do in order to recognize
and compensate Executive fairly for the value of his services.

         8.       DEATH OR DISABILITY.

                  8.1 If Executive shall die during the term hereof, this
Agreement shall immediately terminate, except that Executive's legal
representatives or designated beneficiaries shall be entitled to receive (i) the
Base Salary due to Executive hereunder to the last day of the third month
following the month in which his death occurs, payable in accordance with the
Company's regular payroll practices, (ii) a portion of the Annual Bonus payable
under Section 4 (determined as provided under Section 8.4), based on the
Company's Adjusted Net Income through the month of the bonus year preceding the
month in which death occurs; and (iii) all other payments and entitlements
available upon death under any employee benefit program covering the Executive
as of the date of death. Except for the payments required pursuant to this
Section 8.1, no payments shall be made for any period after Executive's death.

                  8.2 In the event of the Disability (as hereinafter defined) of
the Executive, the Executive shall be entitled to continue to receive from the
Company and its several benefit plans an amount equal to his Base Salary
(prorated as may be necessary) in accordance with the terms of Section 3 hereof
through the last day of the third month following the month in which Executive's
employment hereunder is terminated as a result of such Disability. At any time
after the date of the Notice (as hereinafter defined) and during the continuance
of the Executive's Disability, the Company may at any time thereafter terminate
Executive's employment hereunder by written notice to the Executive. The term
"Disability" shall mean physical or mental illness or


                                       -6-
<Page>

injury which prevents the Executive from performing his customary duties for the
Company for a period of twenty-five (25) consecutive business days or an
aggregate period of ninety (90) days out of any consecutive twelve (12) months.
The date of commencement of Disability shall be the date set forth in the notice
of a determination of Disability (the "Notice") given by Company to the
Executive at any time following a determination of Disability, which date shall
not be earlier than the date the Notice is given by Company. A determination of
Disability by Company shall be solely for the purposes of this Section 8.2 and
shall in no way affect the Executive's status under any benefit plan applicable
to the Executive.

                  8.3 Upon the occurrence of a Disability, and unless the
Executive's employment shall have been terminated as provided in Section 8.2,
the Executive shall continue to perform such services for Company, consistent
with his duties under Section 1 hereof, as he is reasonably capable of
performing in light of the condition giving rise to a Disability. All payments
due under Section 8.2 shall be payable in accordance with Company's regular
payroll practices. Those payments, together with the aggregate amount of all
periodic payments which the Executive is entitled to receive under all workers
compensation plans, disability plans and accident, health or other insurance
plans or programs maintained for the Executive by Company (or by any company
controlling, controlled by or under common control with the Company), shall be
not less than Executive's Base Salary for the month or period in question.

                  8.4 If the Executive's employment is terminated due to
Disability, the Executive shall be entitled, in addition to the payments
described in Section 8.2, to a pro-rated portion of the Annual Bonus otherwise
payable for the fiscal year in which such Disability occurs, determined by
multiplying the Annual Bonus that would otherwise be payable by a


                                       -7-
<Page>

fraction, the numerator of which is the number of days the Executive was
employed during such fiscal year and the denominator of which is 360.

         9.       TERMINATION FOR CAUSE.

                  9.1 The employment of the Executive may be terminated by the
Company for Cause. For this purpose, "Cause" shall mean:

                           (i)      conviction of the commission of a felony;

                           (ii)     fraudulent or dishonest acts against the
                                    Company;

                           (iii)    illegal drug use on the premises of the
                                    Company at any time or elsewhere during the
                                    working day;

                           (iv)     willful gross misconduct which in the good
                                    faith opinion of a majority of the Board of
                                    Directors of the Company is likely to cause
                                    either significant financial loss to the
                                    Company or significant damage to its
                                    business reputation;

                           (v)      willful and repeated misconduct constituting
                                    bad faith in performing the Executive's
                                    obligations; or

                           (vi)     repeated gross neglect of the Executive's
                                    duties.

The Executive's employment shall not be terminated for Cause under clauses (ii),
(iv), (v) or (vi) unless (a) the Executive has received at least 15 days notice
of a meeting of the Board of Directors to consider the existence of Cause with
an opportunity to be heard before the Board, and the Board has determined, based
upon credible evidence, that grounds for Cause exist, AND (b) the misconduct or
breaches on which an assertion of Cause is based are not cured within 30 days
thereafter if such misconduct or breaches are capable of being cured.


                                       -8-
<Page>

                  9.2 In the event of a termination for Cause, the Executive
shall (a) be entitled to any unpaid Base Salary pro rated up to the date of
termination, and (b) have no further rights under this Agreement or under any
Incentive Option issued hereunder.

         10.      TERMINATION UPON CHANGE OF CONTROL OR BY COMPANY WITHOUT
                  CAUSE.

                  10.1 A "Change in Control" shall occur: (A) if any Person, or
combination of Persons, (as hereinafter defined), or any affiliate of any
Person, is or becomes the "beneficial owner" (as defined in Rule 13d-3
promulgated under the Securities Exchange Act of 1934) directly or indirectly,
of securities of the Company representing twenty- five percent (25%) or more of
the total number of outstanding shares of common stock of the Company; or (B) if
individuals who, at the date of this Agreement, constitute the Board (the
"Incumbent Directors") cease, for any reason, to constitute at least a majority
thereof, provided that any new director whose election was approved by the
favorable vote of at least 75% of the Incumbent Directors shall be treated as an
Incumbent Director. For purposes hereof, "Person" shall mean any individual,
partnership, joint venture, association, trust, or other entity, including a
"group" as referred to in section 13(d)(3) of the Securities Exchange Act of
1934.

                  10.2 If a Change in Control occurs, and if there subsequently
occurs a material adverse change, without the Executive's written consent, in
the Executive's working conditions or status, including but not limited to a
significant change in the nature or scope of the Executive's authority, powers,
duties or responsibilities, or a reduction in the level of support services or
staff, then, whether or not such change would otherwise constitute a breach of
this Agreement by the Company, this Agreement may be terminated by notice given
by the Executive, specifying the Change of Control and significant adverse
change or changes.

         10.3 Upon the termination of this Agreement in accordance with Section

damages, to:

                  (a) All unpaid Base Salary pro-rated up to the date of
         termination; and

                  (b) The greatest of (i) the full Annual Bonus for the entire
         year in which the termination referred to in Section 10.2 takes place,
         or (ii) the portion of the Annual Bonus earned from the first day of
         the fiscal year in which such termination occurred until the date of
         the Change of Control, or (iii) the portion of the Annual Bonus earned
         from the first day of the fiscal year in which such termination
         occurred until the effective date of such termination; and

                  (c) A severance payment equal to the sum of (i) the Base
         Salary in effect for the prior fiscal year and (ii) the Annual Bonus
         paid (or payable) on account of such prior fiscal year; and

                  (d) All benefits available under the Company's employee
         benefit programs, to the extent applicable to senior executives
         voluntarily and amicably retiring from employment with the Company.

                  10.4 In the event that the Company shall actually or
constructively terminate this Agreement without cause (and with or without a
Change of Control), the Executive shall be entitled to the same payments,
compensation and rights as provided in the case of a termination by the
Executive under Section 10.3.

                  10.5 The payments, and other compensation and benefits to
which the Executive is entitled under this Section 10 shall be made available to
the Executive no later than ten (10) days after the date of any termination
referred to in Section 10.2, 10.3 or 10.4.

<Page>

                  10.6 In the event that Executive receives the payments, and
other compensation and benefits referred to in this Section 10, he will be bound
by the restrictive provisions of Section 12 for the period therein provided.

         11.      TERMINATION BY EXECUTIVE.

                  11.1 If the Executive shall terminate his employment under
this Agreement prior to the third anniversary of the date hereof without either
(i) a Change of Control or (ii) the express written consent of the Company,
then, for purposes of establishing the rights of the Executive upon such
termination, such termination shall be deemed the equivalent of a termination
for Cause under Section 9.1, and the Executive shall have only those rights with
regard to compensation as are set forth in Section 9.2, and the restrictive
provisions of Section 12 below shall fully apply.

                  11.2 If the Executive shall terminate his employment under
this Agreement after the third anniversary of the date hereof without either (i)
a Change of Control or (ii) the express written consent of the Company, then,
for purposes of establishing the rights of the Executive upon such termination,
the Executive shall be entitled to receive all unpaid Base Salary pro-rated up
to the date of termination.

                  11.3 In the case of a termination pursuant to Section 11.2,
the restrictions set forth in Section 12 shall apply to Executive for the period
therein stated, and the Executive shall receive the compensation set forth

<Page>

         12.      RESTRICTIVE COVENANTS.

                  12.1 During such time as this Agreement shall be in effect
and, except as otherwise explicitly stated herein, for a period of twelve (12)
months following the termination of Executive's employment, and without the
Company's prior written consent (which may be withheld for any reason or for no
reason in Company's sole discretion), Executive shall not do anything in any way
inconsistent with his duties to or adverse to the interests of Company, and
shall not, directly or indirectly, himself or by or through a family member or
otherwise, alone or as a member of a partnership or joint venture, or as a
principal, officer, director, consultant, employee or stockholder of any other
entity, compete with Company or be engaged in or connected with any other
business competitive with that of Company, except that Executive may own as a
passive investment not more than five percent (5%) of the securities of any
publicly held corporation that may engage in a business competitive with that of
Company.

                  12.2 In view of the fact that Executive will be brought into
close contact with many confidential affairs of Company not readily available to
the public, Executive agrees during the Term of this Agreement and thereafter:

                  (a) to keep secret and retain in the strictest confidence all
         information about (i) research and development plans and operations,
         new technology, pending or proposed license agreements, products,
         financial condition and other financial affairs (such as costs,
         pricing, plans for future development, joint ventures, methods of
         operation and marketing goals) of the Company; (ii) its employment
         policies and plans; and (iii) any other proprietary information
         relating to the Company, its operations, businesses, financial
         condition and financial affairs (collectively, the "Confidential
         Information") and,


                                      -12-
<Page>

         for such time as Company is operating, not to disclose the Confidential
         Information to anyone not then an officer, director or authorized
         employee of Company, either during or after the term of this agreement,
         except in the course of performing his duties hereunder or with
         Company's express written consent or except to the extent that such
         confidential information can be shown to have been in the public domain
         through no fault of Executive; and

                  (b) to deliver to Company within ten days after termination of
         his services, or at any time Company may so request, all memoranda,
         notes, records, reports and other documents relating to Company,
         businesses, financial affairs or operations and all property associated
         therewith, which he may then possess or have under his control.

                  12.3 Executive shall not at any time during the twelve month
period following the termination of his employment for any reason whatsoever,
including termination resulting from the natural expiration of the term of this
Agreement, (i) employ any individual who was employed by Company at any time
during the such period or during the twelve calendar months immediately
preceding such termination, or (ii) in any way cause, influence or participate
in the employment of any such individual by anyone else in any business that is
competitive with any of the businesses engaged in by Company.

                  12.4 Executive shall not at any time during the twelve (12)
month period following the termination of his employment, for any reason
whatsoever, including termination resulting from the natural expiration of the
term of this Agreement, directly or indirectly (i) persuade or attempt to
persuade any customer or client or research and development venture partner of
Company to cease doing business with Company or any Affiliate or to reduce the


                                      -13-
<Page>

amount of business it does with Company or (ii) solicit for himself or any
person other than Company, the business of any individual or business which was
a customer or client of Company at any time during the twelve month period
immediately preceding such termination.

                  12.5 Executive acknowledges that the execution and delivery by
him of the covenants set forth in this Section 12 is an essential inducement to
Company to retain Executive and to enter into this agreement, and that Company
would not have retained Executive and entered into this Agreement but for such
covenants. Executive further acknowledges that his services are unique and that
any breach or threatened breach by Executive of any of the foregoing provisions
of this Section 12 cannot be remedied solely by damages. In the event of a
breach or a threatened breach by Executive of any of the provisions of this
Section 12, Company shall be entitled to injunctive relief restraining Executive
and any business, firm, partnership, individual, corporation or other entity
participating in such breach or attempted breach. Nothing herein, however, shall
be construed as prohibiting Company from pursuing any other remedies available
at law or in equity for such breach or threatened breach, including the recovery
of damages and the immediate termination of the employment of Executive
hereunder.

                  12.6 If any of the provisions of, or covenants contained in,

                                   SCHEDULE A

                     RESOLUTION OF DISPUTES OR CONTROVERSIES

(a)      If the parties are deadlocked on any issue arising under the terms of
         this Agreement, a tiebreaker shall be chosen by lot from among a panel
         of three persons designated by the Dean of the College of Business
         Administration at the University of Houston. Each party may present its
         proposal to the designated tiebreaker in written form and may, on a
         date established by the tiebreaker within ten calendar days of the day
         the tiebreaker is chosen, make an oral presentation not to exceed two
         hours in length, accompanied by exhibits and written arguments not to
         exceed 20 pages in length. The designated tiebreaker shall then select
         one of the submitted proposals, without any change or adjustment, and
         shall announce to the parties his or her selection within five calendar
         days of the day of submission.

(b)      The general administrative costs of designating the tiebreaker panel
         shall be paid by the Company. The cost of each specific tiebreaker
         decision shall be borne by the party whose proposal was NOT accepted by
         the tiebreaker. Included in the cost of a tiebreaker decision are costs
         for expert advisors, preparation of special data or other submissions
         to the tiebreaker, and legal fees if a proponent has sought the
         assistance of counsel in presenting a matter to the tiebreaker.
