discharge of the Executive's duties and responsibilities under this Agreement.
The Executive shall not engage in any other business activity, except as may be
approved by the Board; provided, that nothing in this Agreement shall be
construed as preventing the Executive from:



                                      -2-



     a. investing the Executive's assets in any company or other entity in a
manner not prohibited by Section 7(e) and in such form or manner as shall not
require any material activities on the Executive's part in connection with the
operations or affairs of the companies or other entities in which such
investments are made; or

     b. engaging in religious, charitable or other community or non-profit
activities that do not impair the Executive's ability to fulfill the Executive's
duties and responsibilities under this Agreement.

6.   Termination and Termination Benefits. Notwithstanding the provisions of
Section 3, the Executive's employment under this Agreement shall terminate under
the following circumstances set forth in this Section 6.

     a. Termination by the Company for Cause. The Executive's employment under
this Agreement may be terminated for Cause without further liability on the part
of the Company effective immediately upon a vote of the Board and written notice
to the Executive setting forth in reasonable detail the circumstances that the
Company reasonably believes give rise to Cause for termination of the
Executive's employment. Only the following shall constitute Cause for such
termination:

          (i) dishonest statements or acts of the Executive with respect to the
          Company or any affiliate of the Company;

          (ii) the conviction of the Executive for, or the entry of a pleading
          of guilty or nolo contendere (or the equivalent) by the Executive as
          to (A) a felony or (B) any misdemeanor involving moral turpitude,
          deceit, dishonesty or fraud;

          (iii) gross negligence, willful misconduct or willful insubordination
          of the Executive with respect to the Company or any affiliate of the
          Company; or

          (iv) willful breach by the Executive of any of the Executive's
          obligations under this Agreement, which breach results in a material
          injury to the Company.

No act or failure to act shall be considered "willful" for this purpose unless
done, or omitted to be done, by the Executive other than in good faith in the
reasonable belief that such act or omission was in the best interest of the
Company.

     b. Termination by the Executive. The Executive's employment under this
Agreement may be terminated by the Executive by written notice to the Board at
least sixty (60) days prior to such termination. Upon receipt of such notice,
the Company may elect to provide the Executive with pay in lieu of notice. For
purposes of this Section 6(b), the Company is only required to pay the Executive
an amount equal to her Salary pro rated for the period of time for which the
Company waives notice.


                                      -3-



     c. Termination by the Company Without Cause. Subject to the payment of
Termination Benefits pursuant to Section 6(e), the Executive's employment under
this Agreement may be terminated by the Company without cause upon written
notice to the Executive.

     d. Change in Control. The Executive's employment under this Agreement may
be terminated by the Executive for Good Reason within one (1) year of a Change
in Control by written notice to the Board; provided, that the Executive shall
provide the Board with written notice of any such Good Reason at least thirty
(30) days in advance of a voluntary termination of employment and the Company
shall have the opportunity to remedy or cure the asserted basis for any such
Good Reason voluntary termination within such thirty-day period.

          (i) "Change in Control" shall have the meaning set forth in Section
          1.2 of the Stock Plan, without regard to the Board's right to revoke a
          resolution declaring that a Change in Control has occurred.

          (ii) "Good Reason" shall mean:

               (A) the assignment, absent the Executive's written consent, to
               the Executive of any duties substantially inconsistent with the
               Executive's position, status or authority as the Company's
               President and Chief Executive Officer as in effect immediately
               prior to the Change in Control or any alteration in the nature or
               status of the Executive's responsibilities to a significantly
               lesser position;

               (B) loss, absent the Executive's written consent, of the titles
               President or Chief Executive Officer;

               (C) the appointment, absent the Executive's written consent, of
               any other person as Co-President or Co-Chief Executive Officer
               with the Executive;

               (D) material reduction in the Executive's Salary, incentive
               compensation, or benefits or perquisites as in effect immediately
               prior to the Change in Control;

               (E) the relocation of the principal place of the Executive's
               employment after the Change in Control to a location more than 50
               miles from the principal place of the Executive's employment as
               of the Effective Date without the Executive's written consent; or



                                      -4-


               (F) the failure by the Company to assign this Agreement to any
               successor pursuant to Section 14.

     e. Certain Termination Benefits. Unless otherwise specifically provided in
this Agreement or otherwise required by law, all compensation and benefits
payable to the Executive under this Agreement shall terminate on the date of
termination of the Executive's employment under this Agreement. Notwithstanding
the foregoing, in the event of termination of the Executive's employment with
the Company pursuant to Section 6(c) or (d) above, the Company shall provide to
the Executive the following termination benefits ("Termination Benefits"):

          (i) a lump sum amount equal to the Executive's annual Salary at the
          rate then in effect pursuant to Section 4(a);

          (ii) continuation of group health plan benefits to the extent
          authorized by and consistent with 29 U.S.C. ss.1161 et seq. (commonly
          known as "COBRA"), with the cost of the regular premium for such
          benefits shared in the same relative proportion by the Company and the
          Executive as in effect on the date of termination, unless the
          termination of employment pursuant to Section 6(c) or 6(d) occurs
          within one year of a Change in Control, in which case the Company
          shall pay all premiums; and

          (iii) a mutually agreed upon press release announcing the termination
          of the Executive's employment and mutually agreed upon written
          reference from the Company for the Executive.

     The Termination Benefits set forth in (ii) above shall continue for twelve
(12) months after the date of termination so long as the Executive otherwise
remains eligible for continuation under COBRA. Nothing in this Section 6(e)
shall be construed to affect the Executive's right to receive COBRA continuation
entirely at the Executive's own cost to the extent that the Executive may
continue to be entitled to COBRA continuation after the Executive's right to
cost sharing under Section 6(e)(ii) ceases. It is the intention of the Executive
and of the Company that no payments by the Company to or for the benefit of the
Executive under this Agreement or any other agreement or plan, if any, pursuant
to which the Executive is entitled to receive payments or benefits shall be
nondeductible to the Company by reason of the operation of Section 280G of the
Internal Revenue Code ("Code") relating to parachute payments or any like
statutory or regulatory provision. Accordingly, and notwithstanding any other
provision of this Agreement or any such agreement or plan, if by reason of the
operation of said Section 280G or any like statutory or




                                      -5-





regulatory provision, any such payments exceed the amount which can be deducted
by the Company, such payments shall be reduced to the maximum amount which can
be deducted by the Company. To the extent that payments exceeding such maximum
deductible amount have been made to or for the benefit of the Executive, such
excess payments shall be refunded to the Company with interest thereon at the
applicable Federal rate determined under Section 1274(d) of the Internal Revenue
Code, compounded annually, or at such other rate as may be required in order
that no such payments shall be nondeductible to the Company by reason of the
operation of said Section 280G or any like statutory or regulatory provision. To
the extent that there is more than one method of reducing the payments to bring
them within the limitations of said Section 280G or any like statutory or
regulatory provision, the Executive shall determine which method shall be
followed, provided that if the Executive fails to make such determination within
forty-five (45) days after the Company has given notice of the need for such
reduction, the Company may determine the method of such reduction in its sole
discretion.

        f. Disability. If the Executive shall be disabled so as to be unable to
perform the essential functions of the Executive's then existing position or
positions under this Agreement with or without reasonable accommodation, the
Board may remove the Executive from any responsibilities and/or reassign the
Executive to another position with the Company for the remainder of the Term or
during the period of such disability. If the period of disability extends for
more than six (6) months, the Company may terminate the Executive's employment
without further liability on the part of the Company. If any question shall
arise as to whether during any period the Executive is disabled so as to be
unable to perform the essential functions of the Executive's then existing
position or positions with or without reasonable accommodation, the Executive
may, and at the request of the Company shall, submit to the Company a
certification in reasonable detail by a physician selected by the Company to
whom the Executive or the Executive's guardian has no reasonable objection as to
whether the Executive is so disabled or how long such disability is expected to
continue, and such certification shall for the purposes of this Agreement be
conclusive of the issue. The Executive shall cooperate with any reasonable
request of the physician in connection with such certification. If such question
shall arise and the Executive shall fail to submit such certification, the
Company's determination of such issue shall be binding on the Executive. Nothing
in this Section 6(f) shall be construed to waive the Executive's rights, if any,
under existing law including, without limitation, the Family and Medical Leave
Act of 1993, 29 U.S.C. ss.2601 et seq., the Americans with Disabilities Act, 42
U.S.C.
ss.12101 et seq., and Mass.Gen.L. ch. 151B.

        g. Death or Retirement. The Executive's employment under this Agreement
will be deemed to have terminated without further liability on the part of the
Company if the Executive dies or retires.



                                      -6-


7.      Confidential Information, Noncompetition and Assignment.



        a. Confidential Information. As used in this Agreement, "Confidential
Information" means information belonging to the Company which is of value to the
Company in the course of conducting its business and the disclosure of which
could result in a competitive or other disadvantage to the Company. Confidential
Information includes, without limitation, financial information, reports, and
forecasts; inventions, improvements and other intellectual property; trade
secrets; know-how; designs, processes or formulae; research data or results,
inventions, cell lines or products; software; market or sales information or
plans; customer lists; and business plans, prospects and opportunities (such as
possible acquisitions or dispositions of businesses or facilities) which have
been discussed or considered by the management of the Company. Confidential
Information includes information developed by the Executive in the course of the
Executive's employment by the Company, as well as other information to which the
Executive may have access in connection with the Executive's employment.
Confidential Information also includes the confidential information of others
with which the Company has a business relationship. Notwithstanding the
foregoing, Confidential Information does not include information in the public
domain, unless due to breach of the Executive's duties under Section 7(a). The
Executive understands and agrees that the Executive's employment creates a
relationship of confidence and trust between the Executive and the Company with
respect to all Confidential Information. At all times, both during the
Executive's employment with the Company and after its termination, the Executive
will keep in confidence and trust all such Confidential Information, and will
not use or disclose any such Confidential Information without the written
consent of the Company, except as may be necessary in the ordinary course of
performing the Executive's duties to the Company.

        b. Assignment of Rights. Any and all information, data, inventions,
discoveries, materials, notebooks and other work product which the Executive
conceives, develops or acquires during her employment with the Company or within
six (6) months after the termination of Executive's employment with the Company,
which directly or indirectly relates to work performed for the Company shall be
the sole and exclusive property of the Company. The Executive shall promptly
execute any and all documents necessary and take such further actions as the
Company may deem necessary to assign any and all of the Executive's right, title
and interest in such property to the Company. The Executive may publish research
results after the Company, in its sole discretion, has reviewed, for purposes of
determining patentability and maintaining trade secrets, and has approved the
proposed publication.

        c. Intellectual Property. During the Executive's employment at the
Company, the Executive shall promptly assist with and execute any and all
applications, assignments or other documents which an officer or director of the
Company shall deem necessary or useful in order to obtain and maintain patent,
trademark or other intellectual property protection for the Company's products
or services. After the termination date of her employment with the Company, the
Executive shall use reasonable efforts to assist the Company on intellectual
property matters as they relate to her employment, and the Company shall
reasonably compensate the Executive for her time and expense.



                                      -7-


        d. Documents, Records, etc. All documents, records, data, apparatus,
equipment and other physical property, whether or not pertaining to Confidential
Information, which are furnished to the Executive by the Company or are produced
by the Executive in connection with the Executive's employment will be and
remain the sole property of the Company. The Executive will return to the
Company all such materials and property as and when requested by the Company. In
any event, the Executive will return all such materials and property immediately
upon termination of the Executive's employment for any reason. The Executive
will not retain with the Executive any such material or property or any copies
thereof after such termination.

        e. Noncompetition and Nonsolicitation. During the Term and for one (1)
year thereafter, the Executive (i) will not, directly or indirectly, whether as
owner, partner, shareholder, consultant, agent, employee, co-venturer or
otherwise, engage, participate, assist or invest in any Competing Business (as
hereinafter defined); (ii) will refrain from directly or indirectly employing,
attempting to employ, recruiting or otherwise soliciting, inducing or
influencing any person to leave employment with the Company (other than
terminations of employment of subordinate employees undertaken in the course of
the Executive's employment with the Company); and (iii) will refrain from
soliciting or encouraging any customer or supplier to terminate or otherwise
modify adversely its business relationship with the Company. The Executive
understands that the restrictions set forth in this Section 7(e) are intended to
protect the Company's interest in its Confidential Information and established
employee, customer and supplier relationships and goodwill, and agrees that such
restrictions are reasonable and appropriate for this purpose.

        For purposes of this Agreement, the term "Competing Business" shall mean
a business enterprise, whether for profit or not for profit, engaged in the
research, development or marketing of products or services in or relating to T
Cell antigen receptor, complement receptor or other technology fields or
businesses in which the Company is engaged or the Company has investigated
entering within one year prior to termination of the Executive's employment.
Notwithstanding the foregoing, the Executive may own up to one percent (1%) of
the outstanding stock of a publicly held corporation which constitutes or is
affiliated with a Competing Business. The Executive may request the Company to
waive, and the Company, in its sole discretion, may waive its rights under this
Subsection 7(e).

8. Third-Party Agreements and Rights. The Executive hereby confirms that the
Executive is not bound by the terms of any agreement with any previous Company
or other party which restricts in any way the Executive's use or disclosure of
information or the Executive's engagement in any business. The Executive
represents to the Company that the Executive's execution of this Agreement, the
Executive's employment with the Company and the performance of the Executive's
proposed duties for the Company will not violate any obligations the Executive
may have to any such previous Company or other party. In the 





                                      -8-


Executive's work for the Company, the Executive will not disclose or make use of
any information in violation of any agreements with or rights of any such
previous Company or other party, and the Executive will not bring to the
premises of the Company any copies or other tangible embodiments of non-public
information belonging to or obtained from any such previous employment or other
party.






9. Litigation and Regulatory Cooperation. During and for six (6) years after the
Executive's employment, the Executive shall cooperate fully with the Company in
the defense or prosecution of any claims or actions now in existence or which
may be brought in the future against or on behalf of the Company which relate to
events or occurrences that transpired while the Executive was employed by the
Company. The Executive's full cooperation in connection with such claims or
actions shall include, but not be limited to, being available to meet with
counsel to prepare for discovery or trial and to act as a witness on behalf of
the Company at mutually convenient times. During and for six (6) years after the
Executive's employment, the Executive also shall cooperate fully with the
Company in connection with any investigation or review of any federal, state or
local regulatory authority as any such investigation or review relates to events
or occurrences that transpired while the Executive was employed by the Company.
The Company shall reimburse the Executive for any reasonable out-of-pocket
expenses incurred in connection with the Executive's performance of her
obligations pursuant to this Section 9. The Company shall pay the Executive at
the rate of $300 per hour (said rate to be adjusted for inflation from and after
1998 based on then applicable Department of Labor indices for determining
inflation rates in the Boston metropolitan area) for all time spent in the
performance of her obligations pursuant to this Section 9 following the
termination of her employment, other than time spent actually testifying under
oath or directly responding to questions by governmental agents.

10. Injunction. The Executive agrees that it would be difficult to measure any
damages caused to the Company which might result from any breach by the
Executive of the promises set forth in Section 7, and that in any event money
damages would be an inadequate remedy for any such breach. Accordingly, subject
to Section 11 of this Agreement, the Executive agrees that if the Executive
breaches, or proposes to breach, any portion of this Agreement, the Company
shall be entitled, in addition to all other remedies that it may have, to an
injunction or other appropriate preliminary equitable relief to restrain any
such breach without showing or proving any actual damage to the Company.






11. Arbitration of Disputes. Any controversy or claim arising out of or relating
to this Agreement or the breach thereof or otherwise arising out of the
Executive's employment or the termination of that employment (including, without
limitation, any claims of unlawful employment discrimination whether based on
age or otherwise) shall, to the fullest extent permitted by law, be settled by
arbitration in any forum and form agreed upon by the parties or, in the absence
of such an agreement, under the auspices of the American Arbitration Association
("AAA") in Boston, Massachusetts in accordance with the Employment Dispute
Resolution




                                      -9-


Rules of the AAA, including, but not limited to, the rules and procedures
applicable to the selection of arbitrators, except that the arbitrator shall
apply the law as established by decisions of the U.S. Supreme Court, the Court
of Appeals for the First Circuit, the U.S. District Court for the District of
Massachusetts and the Supreme Judicial Court of the Commonwealth of
Massachusetts in deciding the merits of claims and defenses under state or
federal law as applicable to the claims raised, including any state or federal
anti-discrimination law. In the event that any person or entity other than the
Executive or the Company may be a party with regard to any such controversy or
claim, such controversy or claim shall be submitted to arbitration subject to
such other person or entity's agreement. Judgment upon the award rendered by the
arbitrator may be entered in any court having jurisdiction thereof. This Section
11 shall be specifically enforceable. Notwithstanding the foregoing, this
Section 11 shall not preclude either party from pursuing a court action for the
sole purpose of obtaining a temporary restraining order or other preliminary
equitable relief in circumstances in which such relief is appropriate,
including, without limitation, pursuant to Section 10; provided, that any other
relief shall be pursued through an arbitration proceeding pursuant to this
Section 11.

12. Consent to Jurisdiction. To the extent that any court action is permitted
consistent with or requested to enforce Section 7, 10 or 11 of this Agreement,
the parties hereby consent to the jurisdiction of the Superior Court of the
Commonwealth of Massachusetts and the United States District Court for the
District of Massachusetts. Accordingly, with respect to any such court action,
the parties (a) submit to the personal jurisdiction of such courts; (b) consent
to service of process; and (c) waive any other requirement (whether imposed by
statute, rule of court, or otherwise) with respect to personal jurisdiction or
service of process.

13. Taxation. All payments and benefits hereunder shall be subject to
appropriate tax withholding and reporting, as determined by the Company.

14. Integration. This Agreement constitutes the entire agreement between the
parties with respect to the subject matter hereof and supersedes all prior
agreements between the parties with respect to any related subject matter.

15. Assignment; Successors and Assigns, Etc. Neither the Company nor the
Executive may make any assignment of this Agreement or any interest herein, by
operation of law or otherwise, without the prior written consent of the other
party; provided, that the Company may assign its rights under this Agreement
without the consent of the Executive in the event that the Company shall effect
a reorganization, consolidate with or merge into any other corporation,
partnership, organization or other entity, or transfer all or substantially all
of its properties or assets to any other corporation, partnership, organization
or other entity. This Agreement shall inure to the benefit of and be binding
upon the Company and the Executive, their respective successors, executors,
administrators, heirs and permitted assigns.




                                      -10-


16. Enforceability. If any portion or provision of this Agreement (including,
without limitation, any portion or provision of any section of this Agreement)
shall to any extent be declared illegal or unenforceable by a court of competent
jurisdiction, then the remainder of this Agreement, or the application of such
portion or provision in circumstances other than those as to which it is so
declared illegal or unenforceable, shall not be affected thereby, and each
portion and provision of this Agreement shall be valid and enforceable to the
fullest extent permitted by law.






17. Waiver. No waiver of any provision hereof shall be effective unless made in
writing and signed by the waiving party. The failure of any party to require the
performance of any term or obligation of this Agreement, or the waiver by any
party of any breach of this Agreement, shall not prevent any subsequent
enforcement of such term or obligation or be deemed a waiver of any subsequent
breach.

18. Notices. Any notices, requests, demands and other communications provided
for by this Agreement shall be sufficient if in writing and delivered in person
or sent by a nationally recognized overnight courier service or by registered or
certified mail, postage prepaid, return receipt requested, to the Executive at
the last address the Executive has filed in writing with the Company or, in the
case of the Company, at its main offices, attention of the Chief Executive
Officer, and shall be effective on the date of delivery in person or by courier
or three (3) days after the date mailed.

19.     Amendment.  This Agreement may be amended or modified only by a written
instrument signed by the Executive and by a duly authorized representative of
the Company.

20. Governing Law. This is a Massachusetts contract and shall be construed under
and be governed in all respects by the laws of the Commonwealth of
