To:      Jacques Assour, Ph.D.                              As of April 1, 1998
         118 Northgate Circle
         Melville, NY  11747


         The undersigned, Centennial Technologies, Inc., a Delaware corporation
(the "Company"), hereby agrees with you as follows:

         1. POSITION AND RESPONSIBILITIES.

                  1.1 You shall serve as the Senior Vice President of Operations
of the Company or in a position designated by the Company's Chief Executive
Officer, and shall perform such functions as are customarily associated with
such capacity from time to time at the Company's headquarters or such place or
places as are appropriate and necessary in connection with such employment.
These functions shall include, among other things, building positive and
productive relationships with the Company's customers, vendors and suppliers;
the training, development and mentoring of subordinate personnel; the hiring and
assimilation of personnel to assume director positions in the areas of
management information systems, procurement and engineering, and other functions
as delegated from time to time by the Company's Chief Executive Officer.

                  1.2 You will, to the best of your ability, devote your full
time and best efforts to the performance of your duties hereunder and the
business and affairs of the Company. You agree to perform such duties consistent
with your position as may be lawfully and reasonably assigned to you by the
Company's Chief Executive Officer from time to time. Such duties may include
similar responsibilities with companies in which the Company has a majority
ownership interest.

                  1.3 You will duly, punctually and faithfully perform and
observe any and all lawful rules and regulations that the Company may now or
shall hereafter establish governing the conduct of its business.

                                      -1-


         2. TERM OF EMPLOYMENT.

                  2.1 The term of this Agreement shall be for two (2) years,
subject to earlier termination in accordance with Section 2.2 hereof.
Thereafter, this Agreement may be renewed upon the written agreement of you and
the Company. The term of this Agreement and any renewal thereof shall not to be
construed as an agreement, either expressed or implied, to employ you for a
stated term, and shall in no way alter the Company's policy of employment at
will, allowing either you or the Company to remain free to terminate the
employment relationship with or without cause at any time.

                  2.2 The Company shall have the right to terminate your
employment at any time either (a) for "cause" (as defined herein), or (b) upon
thirty (30) days' notice without cause. If the Company terminates your
employment for cause, the Company shall be obligated to pay you an amount equal
to your salary and vacation pay which is accrued and unpaid up to the date of
such termination. If the Company terminates your employment without cause, the
Company shall be obligated to pay you your Base Salary (as defined in EXHIBIT A
attached hereto) for a period of six (6) months (the "Severance Period"). The
Company shall also continue in full force and effect for the Severance Period
all health and insurance benefits that you enjoyed at the time of your
termination without cause, and all other benefits which applicable law requires
to be continued. These severance payments would be in lieu of all other
severance by the Company to which you might be entitled and is conditioned upon
your execution of a general release in a form satisfactory to the Company.

                  2.3 For purposes of Section 2.2 hereof, the term "cause" shall
mean the following: (i) your involvement in any felony crime, material
arrestable criminal offense (excluding road traffic offenses for which a fine or
non-custodial penalty is imposed), or any crime in connection with your
employment with the Company (including theft of Company assets); or (ii)
material insubordination or your unreasonable failure to take actions permitted
by law and necessary to implement strategies or policies of the Company and
which are consistent with your positions and duties, following written warning
of such material insubordination or unreasonable failure; or (iii) drunkenness
or use of any drug or narcotic which adversely affects your job performance; or
(iv) any knowing or intentional misrepresentation of significant information
important to the operating condition of the Company; or (v) acting in material
breach or contravention of any non-competition, non-disclosure or
non-solicitation covenants hereof, or (vi) after written warning from the
Company's Chief Executive Officer, continued willful failure to fulfill the job
functions outlined in paragraph 1.1 of this Agreement.

         3. COMPENSATION. You shall receive the compensation and benefits set
forth on Exhibit A hereto ("Compensation") for all services to be rendered by
you hereunder and for your transfer of property rights, if any, pursuant to an
agreement relating to inventions and non-disclosure dated as of September 15,
1997 attached hereto and made a part hereof as EXHIBIT C 



                                      -2-


between you and the Company (the "Invention and Non-Disclosure Agreement") and
pursuant to an agreement relating to non-competition and non-solicitation dated
as of September 15, 1997 attached hereto and made a part hereof as EXHIBIT D
between you and the Company (the "Non-Competition and Non-Solicitation
Agreement").

         4. OTHER ACTIVITIES DURING EMPLOYMENT.

                  4.1 Except for any outside employments and directorships
currently held by you as listed on EXHIBIT B hereto, if any, and except with the
prior written consent of the Company's Board of Directors (which approval shall
not be unreasonably withheld), you will not during the term of this Agreement
undertake or engage in any other employment, occupation or business enterprise
other than one in which you are an inactive investor.

                  4.2 You hereby agree that, except as disclosed on EXHIBIT B
hereto, during your employment hereunder, you will not, directly or indirectly,
engage (a) individually, (b) as an officer, (c) as a director, (d) as an
employee, (e) as a consultant, (f) as an advisor, (g) as an agent (whether a
salesperson or otherwise), (h) as a broker, or (i) as a partner, coventurer,
stockholder or other proprietor owning directly or indirectly more than one
percent (1%) interest, in any firm, corporation, partnership, trust,
association, or other organization which is engaged in any line of business
engaged in or under demonstrable development by the Company (such firm,
corporation, partnership, trust, association, or other organization being
hereinafter referred to as a "Prohibited Enterprise"). You hereby represent that
you are not presently engaged in any of the foregoing capacities described in
(a) through (i) in any Prohibited Enterprise.

         5. FORMER EMPLOYERS.

                  5.1 You represent and warrant that your employment by the
Company will not conflict with and will not be constrained by any prior or
current employment, consulting agreement or relationship whether oral or
written. You represent and warrant that you do not possess confidential
information arising out of any such employment, consulting agreement or
relationship which, in your best judgment, would be utilized in connection with
your employment by the Company.

                  5.2 If, in spite of the second sentence of Section 5.1, you
should find that confidential information belonging to any other person or
entity might be usable in connection with the Company's business, you will not
intentionally disclose to the Company or use on behalf of the Company any
confidential information belonging to any of your former employers; but during
your employment by the Company you will use in the performance of your duties
all information which is generally known and used by persons with training and
experience comparable to your own, all information which is common knowledge in
the industry or otherwise legally in the public domain.

                                      -3-


         6. PROPRIETARY INFORMATION AND INVENTIONS. You agree to execute,
deliver and be bound by the provisions of the Invention and Non-Disclosure
Agreement attached hereto as EXHIBIT C and incorporated herein.

         7. POST-EMPLOYMENT ACTIVITIES. You agree to execute, deliver and be
bound by the provisions of the Non-Competition and Non-Solicitation Agreement
attached hereto as EXHIBIT D and incorporated herein.

         8. REMEDIES. Your obligations under the Proprietary Information and
Inventions Agreement and the provisions of Sections 9, 10 and 11 of this
Agreement (as modified by Section 12, if applicable) shall survive the
expiration or termination of your employment (whether through your resignation
or otherwise) with the Company. You acknowledge that a remedy at law for any
breach or threatened breach by you of the provisions of this Agreement or the
Proprietary Information and Inventions Agreement would be inadequate and you
therefore agree that the Company shall be entitled to injunctive relief in case
of any such breach or threatened breach.

         9. ASSIGNMENT. This Agreement and the rights and obligations of the
parties hereto shall bind and inure to the benefit of any successor or
successors of the Company by reorganization, merger or consolidation and any
assignee of all or substantially all of its business and properties, but, except
as to any such successor or assignee of the Company, neither this Agreement nor
any rights or benefits hereunder may be assigned by the Company or by you,
except by operation of law or by a further written agreement by the parties
hereto.

         10. CONFIDENTIALITY. You 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
your employment, any trade secrets, confidential information, knowledge, data or
other information of the Company relating to products, 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
you may produce, obtain, or otherwise acquire during the course of your
employment, except as herein provided. You 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 a duly authorized representative of the Company.

         11. ARBITRATION. Any dispute concerning this Agreement including, but
not limited to, its existence, validity, interpretation, performance or
non-performance, arising before or after termination or expiration of this
Agreement, shall be settled by a single arbitrator in Boston, 



                                      -4-


Massachusetts, in accordance with the expedited procedures of the commercial
rules then in effect of the American Arbitration Association. Judgment upon any
award may be entered in the highest court, state or federal, having
jurisdiction.

         12. 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 one or more of the provisions contained in
this Agreement is or becomes or is deemed invalid, illegal or unenforceable or
in case any provision 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.

         13. NOTICES. Any notice which the Company is required to or may desire
to give you shall be given by personal delivery or registered or certified mail,
return receipt requested, addressed to you at your address of record with the
Company, or at such other place as you may from time to time designate in
writing. Any notice which you are required or may desire to give to the Company
hereunder shall be given by personal delivery or by registered or certified
mail, return receipt requested, addressed to the Company at its principal
office, or at such other office as the Company may from time to time designate
in writing with a copy to S. Donald Gonson, Esquire, Hale and Dorr, L.L.P.,
Sixty State Street, Boston, Massachusetts 02109. The date of personal delivery
or the date of mailing of any notice under this Section 13 shall be deemed to be
the date of delivery thereof.

         14. 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, such party shall not thereby be deemed to have
waived any preceding or succeeding breach of the same or any other provision of
this Agreement.

         15. COMPLETE AGREEMENT; AMENDMENTS. The foregoing, including Exhibits
A, B, C and D hereto, 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



                                      -5-


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

         16. HEADINGS. The headings of the Sections hereof are inserted for
convenience only and shall not be deemed to constitute a part hereof nor to
affect the meaning of this Agreement.

         17. COUNTERPARTS. This Agreement may be signed in two counterparts,
each of which shall be deemed an original and both of which shall together
constitute one agreement.

         18. GOVERNING LAW. This Agreement shall be governed by and construed
under Massachusetts law, without regard to its conflict of laws principles.

         If you are in agreement with the foregoing, please sign your name below
and also at the bottom of the Invention and Non-Disclosure Agreement and the
Non-Competition and Non-Solicitation Agreement, whereupon this Agreement shall
become binding in accordance with its terms. Please then return this Agreement
to the Company. (You may retain for your records the accompanying counterpart of
this Agreement enclosed herewith).

                                           Very truly yours,

                                           CENTENNIAL TECHNOLOGIES, INC.
