<PAGE>
                  (i) DEFINITION OF CAUSE. As used herein, "CAUSE" means any of
the following: (A) habitual drunkenness under the influence of alcohol by
Employee or illegal use of narcotics; (B) Employee is convicted by a court of
competent jurisdiction, or pleads "no contest" to, a felony or any other conduct
of a criminal nature (other than minor traffic violations) by Employee; (C)
Employee engages in fraud, embezzlement, or any other illegal conduct; (D)
Employee imparts confidential information relating to Employer or its business
to competitors or to other third parties other than in the course of carrying
out Employee's duties; (E) Employee refuses to perform his duties hereunder or
otherwise breaches any covenant, warranty or representation of this Agreement or
Employee's Non-Disclosure and Confidentiality Agreement executed concurrently
herewith, and, except for any conduct described in clauses (A) through (D) of
this Section 6(a)(i), fails to cure such breach (if such breach is then capable
of being cured) within ten (10) business days following written notice thereof
specifying in reasonable detail the nature of such breach, or if such breach is
not capable of being cured in such time, a cure shall not have been diligently
initiated within such ten (10) business day period.

                  (ii) EFFECT OF TERMINATION. Upon termination in accordance
with this Section 6(a), Employee shall be entitled to no further compensation
hereunder other than the Base Salary and other benefits accrued hereunder
through, but not including, the effective date of such termination. Employer's
exercise of its right to terminate for Cause shall be without prejudice to any
other remedy to which it may be entitled at law, in equity or under this
Agreement.

            (b) VOLUNTARY TERMINATION. Employee may terminate his employment at
any time by giving no less than thirty (30) days' written notice to Employer.

                  (i) NO REASON. Upon termination in accordance with this
Section 6(b), except as otherwise provided in Section 6(b)(ii), below, Employee
shall be entitled to no further compensation hereunder other than the Base
Salary and other benefits accrued hereunder through, but not including, the
effective date of such termination.

                  (ii) GOOD REASON. Notwithstanding anything to the contrary in
Section 6(b)(i) above, if Employee terminates his employment under this Section
6(b) for Good Reason (as defined below), Employee shall be entitled to receive
from Employer all of the compensation and benefits provided for in Section 6(e)
below. As used herein, "GOOD Reason" means any of the following: (A) the
assignment to Employee of duties materially inconsistent with those of other
employees of Employer in like positions where Employee provides written notice
to Employer within six (6) months of such assignment that such duties are
materially inconsistent with those duties of similarly situated employees and
Employer fails to release Employee from his obligation to perform such
inconsistent duties within twenty (20) business days after Employer's receipt of
such notice; or (B) a failure by Employer to comply with any other material
provision of Sections 3 through 5, inclusive, of this Agreement which has not
been cured within fifteen (15) business days after notice of such noncompliance
has been given by Employee to Employer, or if such failure is not capable of
being cured in such time, a cure shall not have been diligently initiated by
Employer within such fifteen (15) business day period.

                                       3
<PAGE>
            (c) TERMINATION DUE TO DEATH OR DISABILITY. This Agreement shall
automatically terminate upon the death of Employee. In addition, if Employee is
unable to perform the essential functions of his job with or without a
reasonable accommodation because of a physical or mental impairment for a period
of six (6) months, Employer may terminate Employee's employment upon written
notice to Employee. Upon termination in accordance with this Section 6(c),
Employee (or Employee's estate, as the case may be) shall be entitled to no
further compensation hereunder other than the Base Salary and other benefits
accrued hereunder through, but not including, the date of death or, in the case
of disability, the date of termination.

            (d) TERMINATION UPON CESSATION OF BUSINESS. Employer shall have the
right to immediately terminate Employee's employment under this Agreement upon a
"Cessation of Business." For purposes of this Agreement, a "CESSATION OF
BUSINESS" shall mean Employer's ceasing to operate in the ordinary course of
business, whether by dissolution, liquidation, sale of assets, consolidation,
merger or otherwise, in connection with, pursuant to or arising out of a good
faith determination by the Board that the continuing operation of the business
in its ordinary course is reasonably likely to render Employer unable to meet
its liabilities as they mature. Upon termination in accordance with the Section
6(d), Employee shall be entitled to no further compensation hereunder other than
the Base Salary and other benefits accrued hereunder through, but not including,
the effective date of such termination. If Employee is so terminated by Employer
pursuant to this Section 6(d) during the Term, Employer shall (i) pay to
Employee the Base Salary, and (ii) provide the same health insurance benefits to
which Employee was entitled hereunder, in each case (i.e., the Base Salary and
health insurance benefits), until the earlier to occur of (A) the expiration of
the remaining portion of the Term, or (B) the expiration of the three (3) month
period commencing on the date Employee is terminated. Employer may make such
payments in accordance with its regular payroll schedule or in a single lump sum
payment in its sole discretion.

            (e) TERMINATION WITHOUT CAUSE. Employer shall have the right,
exercisable upon 30 days' prior written notice, to terminate Employee's
employment under this Agreement for any reason other than set forth in Sections
6(a), (c) and (d) above, at any time during the Term. If Employee is so
terminated by Employer pursuant to this Section 6(e) during the Term, Employer
shall (i) pay to Employee the Base Salary, and (ii) provide the same health
insurance benefits to which Employee was entitled hereunder, in each case (i.e.,
the Base Salary and health insurance benefits), until the earlier to occur of
(A) the expiration of the remaining portion of the Term, or (B) the expiration
of the twelve (12) month period commencing on the date Employee is terminated.
Employer may make such payments in accordance with its regular payroll schedule
or in a single lump sum payment in its sole discretion.

      7. PUBLICITY. During the term of this Agreement and for a period of one
(1) year thereafter, Employee shall not, directly or indirectly, originate or
participate in the origination of any publicity, news release or other public
announcements, written or oral, whether to the public

                                       4
<PAGE>
press or otherwise, relating to this Agreement, to any amendment hereto, to
Employee's employment hereunder or to the Company, without the prior written
approval of the Company.

      8. RESTRICTIVE COVENANTS.

            (a) NON-COMPETITION. In consideration of the benefits of this
Agreement, including Employee's access to and limited use of proprietary and
confidential information of the Company, as well as training, education and
experience provided to Employee by the Company directly and/or as a result of
work projects assigned by the Company with respect thereto, Employee hereby
covenants and agrees that during the term of this Agreement and for a period of
twelve (12) months following termination of this Agreement, regardless of how
such termination may be brought about, Employee shall not, directly or
indirectly, as proprietor, partner, stockholder, director, officer, employee,
consultant, joint venturer, investor or in any other capacity, engage in, or
own, manage, operate or control, or participate in the ownership, management,
operation or control, of any entity which engages anywhere in the world in any
business activity which is competitive to current business activities in which
the Company participates during Employee's employment with the Company;
PROVIDED, HOWEVER, the foregoing shall not, in any event, prohibit Employee from
purchasing and holding as an investment not more than 1% of any class of
publicly traded securities of any entity which conducts a business in
competition with the business of the Company, so long as Employee does not
participate in any way in the management, operation or control of such entity.
It is further recognized and agreed that, even though an activity may not be
restricted under the foregoing provision, Employee shall not during the term of
this Agreement and for a period of twelve (12) months following termination of
this Agreement, regardless of how such termination may be brought about, provide
any services to any person or entity which may be used against, or in conflict
with the interests of, the Company or its customers or clients.

            (b) JUDICIAL REFORMATION. Employee acknowledges that, given the
nature of the Company's business, the covenants contained in Section 8(a)
establish reasonable limitations as to time, geographic area and scope of
activity to be restrained and do not impose a greater restraint than is
reasonably necessary to protect and preserve the goodwill of the Company's
business and to protect its legitimate business interests. If, however, Section
8(a) is determined by any court of competent jurisdiction to be unenforceable by
reason of its extending for too long a period of time or over too large a
geographic area or by reason of it being too extensive in any other respect or
for any other reason, it will be interpreted to extend only over the longest
period of time for which it may be enforceable and/or over the largest
geographic area as to which it may be enforceable and/or to the maximum extent
in all other aspects as to which it may be enforceable, all as determined by
such court.

                                       5

            (c) CUSTOMER LISTS; NON-SOLICITATION. In consideration of the
benefits of this Agreement, including Employee's access to and limited use of
proprietary and confidential information of the Company, as well as training,
education and experience provided to Employee by the Company directly and/or as
a result of work projects assigned by the Company with respect thereto, Employee
hereby further covenants and agrees that for a period of twelve (12) months
following the termination of this Agreement, regardless of how such termination
may be brought about, Employee shall not, directly or indirectly, (i) use or
make known to any person or entity the names or addresses of any clients or
customers of the Company or any other information pertaining to them, (ii) call
on for the purpose of competing, solicit, take away or attempt to call on,
solicit or take away any clients or customers of the Company on whom Employee
called or with whom he became acquainted during his employment with the Company,
nor (iii) recruit or attempt to recruit any employees of the Company.

            (d) AFFILIATES. When used in this Section 8, the term "Company"

Interluekin Genetics, Inc.

      9. MISCELLANEOUS.

            (a) WITHHOLDINGS. All payments to Employee hereunder shall be made
after reduction for all federal, state and local withholding and payroll taxes,
all as determined under applicable law and regulations, and Employer shall make
all reports and similar filings required by such law and regulations with
respect to such payments, withholdings and taxes.

            (b) SUCCESSION. This Agreement shall inure to the benefit of and
shall be binding upon Employer, its successors and assigns. The obligations and
duties of Employee hereunder shall be personal and not assignable.

            (c) NOTICES. Any and all notices, demands, requests or other
communications hereunder shall be in writing and shall be deemed duly given when
personally delivered to or transmitted overnight express delivery or by
facsimile to and received by the party to whom such notice is intended (provided
the original thereof is sent by mail, in the manner set forth below, on the next
business day after the facsimile transmission is sent), or in lieu of such
personal delivery or overnight express delivery or facsimile transmission, on
receipt when deposited in the United States mail, first-class, certified or
registered, postage prepaid, return receipt requested, addressed to the
applicable party at the address set forth below such party's signature to this
Agreement. The parties may change their respective addresses for the purpose of
this Section 9(c) by giving notice of such change to the other parties in the
manner which is provided in this Section 9(c).

            (d) ENTIRE AGREEMENT. This Agreement contains the entire agreement
of the parties relating to the subject matter hereof, and it replaces and
supersedes any prior agreements between the parties relating to said subject
matter.

                                       6
<PAGE>
            (e) HEADINGS. The headings of Sections herein are used for
convenience only and shall not affect the meaning of contents hereof.

            (f) WAIVER; AMENDMENT. No provision hereof may be waived except by a
written agreement signed by the waiving party. The waiver of any term or of any
condition of this Agreement shall not be deemed to constitute the waiver of any
other term or condition. This Agreement may be amended only by a written
agreement signed by the parties hereto.

            (g) SEVERABILITY. If any of the provisions of this Agreement shall
be held unenforceable by the final determination of a court of competent
jurisdiction and all appeals therefrom shall have failed or the time for such
appeals shall have expired, such provision or provisions shall be deemed
eliminated from this Agreement but the remaining provisions shall nevertheless
be given full effect. In the event this Agreement or any portion hereof is more
restrictive than permitted by the law of the jurisdiction in which enforcement
is sought, this Agreement or such portion shall be limited in that jurisdiction
only to the extent required by the law of that jurisdiction.

            (h) GOVERNING LAW. This Agreement shall be governed by and construed
in accordance with the laws of the State of Texas.

            (i) ARBITRATION. Except for the provisions of Sections 7 and 8 with
regard to which the Company expressly reserves the right to petition a court
directly for injunctive or other relief, any dispute arising out of or relating
to this Agreement, or the breach, termination or the validity hereof, shall be
settled by arbitration in accordance with the Commercial Arbitration Rules of
the American Arbitration Association. Judgment upon the award rendered by the
arbitrator or arbitrators may be entered in any court having jurisdiction
thereof. THE ARBITRATOR OR ARBITRATORS ARE NOT EMPOWERED TO AWARD DAMAGES IN
EXCESS OF COMPENSATORY DAMAGES (INCLUDING REASONABLE ATTORNEYS FEES AND EXPERT
WITNESS FEES) AND EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT TO RECOVER SUCH
DAMAGES (INCLUDING, WITHOUT LIMITATION, PUNITIVE DAMAGES) IN ANY FORUM. The
arbitrator or arbitrators may award equitable relief in those circumstances
where monetary damages would be inadequate. The arbitrator or arbitrators shall
be required to follow the applicable law as set forth in the governing law
section of this Agreement. The arbitrator or arbitrators shall award reasonable
attorneys fees and costs of arbitration to the prevailing party in such
arbitration.

            (j) EQUITABLE RELIEF. In the event of a breach or a threatened
breach by Employee of any of the provisions contained in Sections 7 or 8 of this
Agreement, Employee acknowledges that the Company will suffer irreparable injury
not fully compensable by money damages and, therefore, will not have an adequate
remedy available at law. Accordingly, the Company shall be entitled to obtain
such injunctive relief or other equitable remedy from any court of competent
jurisdiction as may be necessary or appropriate to prevent or curtail any such
breach, threatened or actual, without having to post bond. The foregoing shall
be in addition to

                                       7
<PAGE>
and without prejudice to any other rights that the Company may have under this
Agreement, at law or in equity, including, without limitation, the right to sue
for damages.

      IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first set forth above.
