     5.3 By the Company For Cause. The Company may terminate Executive for cause

          (a) Executive's conviction for commission of a felony;

          (b) Executive's willful commission of any act of theft, embezzlement

by the Company without Executive's prior consent; or

          (d) the relocation of Executive's principal place of employment to a
location more than 50 miles from Hopkinton, Massachusetts without Executive's
prior consent.

     In the event that Executive terminates this Agreement for good reason
pursuant to this Section 5.4, Executive shall have the right to receive
Executive's compensation as provided hereunder through the effective date of
termination and shall also have the same rights and remedies against the Company
as Executive would have had if the Company had terminated Executive's employment
without cause pursuant to Section 5.1 (including the right to receive the
Severance Amount payable and the Severance Benefits to be provided under Section
5.2).

     5.5 Executive's Voluntary Termination. Executive may, at any time,

the Company at least 90 days prior to the effective date of termination. In the
event of such voluntary termination of this Agreement by Executive: (i)
Executive shall have the right to receive Executive's compensation as provided
hereunder through the effective date of termination; and (ii) the Company on the
one hand, and Executive, on the other hand, shall not have any further right or
remedy against one another except as provided in Sections 6, 7 and 8 hereof
which shall remain in full force and effect.

     5.6 Change of Control. Executive may terminate this Agreement, upon at
least 10 days' prior written notice to the Company at any time within one year
after a "change in control" (as hereinafter defined) of the Company. In the
event Executive terminates this Agreement within one year after a change in
control pursuant to this Section 5.6, (i) Executive shall continue to render
services pursuant hereto and shall continue to receive compensation, as provided
hereunder, through the termination date, (ii) the Company shall pay Executive no
later than the date of such termination, as a single severance payment, an
amount equal to the Severance Amount and (iii) following such termination, the
Company shall provide the Severance Benefits as required by Section 5.2(b). For
purposes of this Agreement, a "change in control" shall mean the occurrence of
any of the following events:

perform services for Executive, or any other person, firm or company. The
restrictions set forth in this Section 7 shall not apply if Executive's
employment is terminated pursuant to Section 5.1, 5.4 or 5.6.

To: Boston Life Sciences, Inc.                          Date: __________________

     The undersigned, in consideration of and as a condition of my employment or
continued employment by you and/or by companies that you own, control, or are
affiliated with or their successors in business (collectively, the "Company"),
hereby agrees as follows:

     1. Confidentiality. I agree to keep confidential, except as the Company may
otherwise consent in writing, and except for the Company's benefit, not to
disclose or make any use of at any time either during or subsequent to my
employment, any Inventions (as hereinafter defined), trade secrets, confidential
information, knowledge, data or other information of the Company relating to
products, franchises, processes, know-how, techniques, methods, designs,
formulas, test data, customer lists, business plans, marketing plans and
strategies, pricing strategies, or other subject matter pertaining to any
business of the Company or any of its affiliates, which I may produce, obtain,
or otherwise acquire during the course of my employment, except as herein
provided. I further agree not to deliver, reproduce or in any way allow any such
trade secrets, confidential information, knowledge, data or other information,
or any documentation relating thereto, to be delivered to or used by any third
parties without specific direction or consent of the Chairman of the Board or
the Chief Executive Officer of the Company. The provisions of this Section 1
shall not apply to such knowledge, data or other information that is generally
known to the public.

     2. Conflicting Employment; Return of Confidential Material. I agree that
during my employment with the Company I will not engage in any other employment,
occupation, consulting or other activity relating to the business in which the
Company is now or may hereafter become engaged, or which would otherwise
conflict with my obligations to the Company. In the event my employment with the
Company terminates for any reason whatsoever, I agree to promptly surrender and
deliver to the Company all trade secrets, confidential information, processes
and records, including, but not limited to, designs, formulae, test data,
customer lists, business plans and strategies, Inventions or other written
memoranda, materials, equipment, drawings, documents and data that I may obtain

description containing or pertaining to any confidential information, knowledge
or data of the Company that I may produce or obtain during the course of my
employment.

     3. Assignment of Inventions.

          3.1 I hereby acknowledge and agree that the Company is the owner of
all Inventions. In order to protect the Company's rights to such Inventions, by
executing this Agreement I hereby irrevocably assign to the Company all my
right, title and interest in and to all Inventions to the Company.

          3.2 For purposes of this Agreement, "Inventions" shall mean all
discoveries, processes, designs, technologies, methods, techniques, devices, or
improvements in any of the foregoing or other ideas, whether or not patentable
or copyrightable and whether or not reduced to practice, made or conceived by me
(whether solely or jointly with others) during the period of my employment with
the Company that relate to the actual or demonstrably anticipated business,
work, or research and development of the Company, or result from or are
suggested by any task assigned to me or any work performed by me for or on
behalf of the Company.

          3.3 Any discovery, process, design, method, technique, technology,
device, or improvement in any of the foregoing or other ideas, whether or not
patentable or copyrightable and whether or not reduced to practice, made or
conceived by me (whether solely or jointly with others) that I develop entirely
on my own time not using any of the Company's equipment, supplies, facilities,
or trade secret information ("Personal Invention") is excluded from this
Agreement provided such Personal Invention (a) does not relate to the actual or
demonstrably anticipated business, research and development of the Company, and
(b) does not result, directly or indirectly, from any work performed by me for
the Company.

     4. Disclosure of Inventions. I agree that in connection with any Invention,
I will promptly disclose such Invention to the Board of Directors of the Company
in order to permit the Company to enforce its property rights to such Invention
in accordance with this Agreement. My disclosure shall be received in confidence
by the Company. If the Company in good faith decides not to use an Invention, it
will advise me of same and the rights to such Invention will revert to me within
a reasonable period of time.

     5. Patents and Copyrights; Execution of Documents.

          5.1 Upon request, I agree to assist the Company or its nominee (at its
expense) during and at any time subsequent to my employment in every reasonable
way to obtain for its own benefit patents and copyrights for Inventions in any
and all countries. Such patents and copyrights shall be and remain the sole and
exclusive property of the Company or its nominee. I agree to perform such lawful
acts as the Company deems to be necessary to allow it to exercise all right,
title and interest in and to such patents and copyrights.

          5.2 In connection with this Agreement, I agree to execute, acknowledge
and deliver to the Company or its nominee upon request and at its expense all
documents, including assignments of title, patent or copyright applications,
assignments of such applications, assignments of patents or copyrights upon
issuance, as the Company may determine necessary or desirable to protect the
Company's or its nominee's interest in Inventions, and/or to use in


                                       11

<PAGE>

obtaining patents or copyrights in any and all countries and to vest title
thereto in the Company or its nominee to any of the foregoing.

     6. Maintenance of Records. I agree to keep and maintain adequate and
current written records of all Inventions made by me (in the form of notes,
sketches, drawings, flowcharts, printouts, diskettes and other records as may be
specified by the Company), which records shall be available to and remain the
sole property of the Company at all times.

     7. Prior Inventions. It is understood that all Personal Inventions, if any,
whether patented or unpatented, which I made prior to my employment by the
Company, are excluded from this Agreement. To preclude any possible uncertainty,
I have set forth on Schedule A attached hereto a complete list of all of my
prior Personal Inventions, including numbers of all patents and patent
applications and a brief description of all unpatented Personal Inventions that
are not the property of a previous employer. I represent and covenant that the
list is complete and that, if no items are on the list, I have no such prior
Personal Inventions. I agree to notify the Company in writing before I make any
disclosure or perform any work on behalf of the Company that appears to threaten
or conflict with proprietary rights I claim in any Personal Invention. In the
event of my failure to give such notice, I agree that I will make no claim
against the Company with respect to any such Personal Invention.

     8. Other Obligations. I acknowledge that the Company from time to time may
have agreements with other persons, companies, entities, Governments or agencies
thereof, that impose obligations or restrictions on the Company regarding
Inventions made during the course of work thereunder or regarding the
confidential nature of such work. I agree to be bound by all such obligations
and restrictions and to take all actions necessary to discharge the Company's
obligations.

     9. Trade Secrets of Others. I represent that my performance of all the
terms of this Agreement and as an employee of the Company does not and will not
breach any agreement to keep confidential proprietary information, knowledge, or
data acquired by me in confidence or in trust prior to my employment with the
Company, and I will not disclose to the Company, or induce the Company to use,
any confidential or proprietary information or material belonging to any
previous employer or others. I agree not to enter into any agreement either
written or oral in conflict herewith.

     10. Post-Employment Activities.

          10.1 For a period of one (1) year after the termination, for any
reason, of my employment with the Company, absent the Company's prior written
approval, I will not directly or indirectly engage in activities similar or
reasonably related to those in which I shall have engaged for the Company during
the two years immediately preceding termination, nor render services similar or
reasonably related to those which I shall have rendered during such time to, any
person or entity whether existing or hereafter established that directly
competes with (or proposes or plans to directly compete with) the Company, or in
other areas where the Company carries on a substantial amount of business
("Direct Competitor"). In addition, I shall not entice,


                                       12

<PAGE>

induce or encourage any of the Company's other employees to engage in any
activity that, were it done by me, would violate any provision of this
Agreement.

          10.2 No provision of this Agreement shall be construed to preclude me
from performing the same services that the Company retains me to perform for any
person or entity that is not a Direct Competitor of the Company upon the
termination of my employment (or any post-employment consultation) so long as I
do not thereby violate any term of this Agreement.

     11. Remedies. My obligations under this Agreement shall survive the
termination of my employment with the Company. I acknowledge that a remedy at
law for any breach or threatened breach by me of the provisions of this
Agreement would be inadequate and I therefore agree that the Company shall be
entitled to injunctive relief in case of any such breach or threatened breach.

     12. Modification. I agree that any subsequent change or changes in my
employment duties, salary or compensation or, if applicable, in any Employment
Agreement between the Company and me, shall not affect the validity or scope of
this Agreement.

     13. Successors and Assigns. This Agreement shall be binding upon my heirs,
executors, administrators or other legal representatives and is for the benefit
of the Company, its successors and assigns.

     14. Interpretation. IT IS THE INTENT OF THE PARTIES THAT in case any one or
more of the provisions contained in this Agreement shall, for any reason, be
held to be invalid, illegal or unenforceable in any respect, such invalidity,
illegality or unenforceability shall not affect the other provisions of this
Agreement, and this Agreement shall be construed as if such invalid, illegal, or
unenforceable provision had never been contained herein. MOREOVER, IT IS THE
INTENT OF THE PARTIES THAT if any provision of this Agreement is or becomes or
is deemed invalid, illegal or unenforceable or in case any one or more of the
provisions contained in this Agreement shall for any reason be held to be
excessively broad as to duration, geographical scope, activity or subject, such
provision shall be construed by amending, limiting and/or reducing it to conform
to applicable laws so as to be valid and enforceable or, if it cannot be so
amended without materially altering the intention of the parties, it shall be
stricken and the remainder of this Agreement shall remain in full force and
effect.

     15. Waivers. No waiver of any right under this Agreement shall be deemed
effective unless contained in a writing signed by the party charged with such
waiver, and no waiver of any right arising from any breach or failure to perform
shall be deemed to be a waiver of any future such right or of any other right
arising under this Agreement. If either party should waive any breach of any
provision of this Agreement, he or it shall not thereby be deemed to have waived
any preceding or succeeding breach of the same or any other provision of this
Agreement.

     16. Complete Agreement, Amendments. The foregoing is the entire agreement
of the parties with respect to the subject matter hereof, superseding any
previous oral or written communications, representations, understandings, or
agreements with the Company or any officer or representative thereof. Any
amendment to this Agreement or waiver by the Company


                                       13

<PAGE>

of any right hereunder shall be effective only if evidenced by a written
instrument executed by the parties hereto, upon authorization of the Company's
Board of Directors.

     17. Headings. The headings of the Sections contained in this Agreement are
inserted for convenience and reference only and in no way define, limit, extend
or describe the scope of this Agreement, or the intent of any provision hereof,
and shall not be deemed to constitute a part hereof nor to affect the meaning of
this Agreement in any way.

     18. Governing Law. This Agreement shall be governed by and construed in
accordance with the internal laws of the Commonwealth of Massachusetts,
excluding its conflict of law principles.

     19. Notices. All notices, requests, demands and communications which are or
may be required to be given hereunder shall be deemed effectively given if and
when sent by registered or certified mail, return receipt requested, postage
prepaid, to the following addresses:

          If to the Company:



          If to Employee:

     21. Conflicts. In the event of any conflict between the provisions of this
agreement and the provisions of the Employment Agreement, the provisions of the
Employment Agreement will govern.

                                        Very truly yours,

Agreed:
Boston Life Sciences, Inc.
