                          CENTENNIAL TECHNOLOGIES, INC.

                          EXECUTIVE RETENTION AGREEMENT

         THIS EXECUTIVE RETENTION AGREEMENT by and between Centennial
Technologies, Inc., a Delaware corporation (the "Company"), and Mary A. Gallahan
(the "Executive") is made as of December 16, 1999 (the "Effective Date").

         WHEREAS, the Company recognizes that, as is the case with many
publicly-held corporations, the possibility of a change in control of the
Company exists and that such possibility, and the uncertainty and questions
which it may raise among key personnel, may result in the departure or
distraction of key personnel to the detriment of the Company and its
stockholders, and

         WHEREAS, the Board of Directors of the Company (the "Board") has
determined that appropriate steps should be taken to reinforce and encourage the
continued employment and dedication of the Company's key personnel without
distraction from the possibility of a change in control of the Company and
related events and circumstances.

         NOW, THEREFORE, as an inducement for and in consideration of the
Executive remaining in its employ, the Company agrees that the Executive shall
receive the severance benefits set forth in this Agreement in the event the
Executive's employment with the Company is terminated under the circumstances
described below subsequent to a Change in Control (as defined in Section 1.1).

         1. KEY DEFINITIONS.

         As used herein, the following terms shall have the following respective
meanings:

                  1.1 "CHANGE IN CONTROL" means an event or occurrence set forth
in any one or more of subsections (a) through (d) below (including an event or
occurrence that constitutes a Change in Control under one of such subsections
but is specifically exempted from another such subsection):

                      (a) the acquisition by an individual, entity or group
(within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange
Act of 1934, as amended (the "Exchange Act")) (a "Person") of beneficial
ownership of any capital stock of the Company if, after such acquisition, such
Person beneficially owns (within the meaning of Rule 13d-3 promulgated under the
Exchange Act) 30% or more of either (i) the then-outstanding shares of common
stock of the Company (the "Outstanding Company Common Stock") or (ii) the
combined voting power of the then-outstanding securities of the Company entitled
to vote generally in the election of directors (the "Outstanding Company Voting
Securities"); PROVIDED, however, that for purposes of this subsection (a), the
following acquisitions shall not constitute a Change in Control: (i) any
acquisition directly from the Company (excluding an acquisition pursuant to the
exercise, conversion or exchange of any security exercisable for, convertible
into or exchangeable for common stock or voting securities of the Company,
unless the Person exercising, converting or exchanging such security acquired
such security directly from the Company or an underwriter or agent of the
Company), (ii) any acquisition by the Company, (iii) any acquisition by any
employee benefit plan (or related trust) sponsored or maintained by the Company
or any corporation controlled by the Company, or (iv) any acquisition by any
corporation pursuant to a transaction which complies with clauses (i) and (ii)
of subsection (c) of this Section 1.1; or

                      (b) such time as the Continuing Directors (as defined

of Directors of a successor corporation to the Company), where the term
"Continuing Director" means at any date a member of the Board (i) who was a
member of the Board on the date of the execution of this Agreement or (ii) who
was nominated or elected subsequent to such date by at least a majority of the
directors who were Continuing Directors at the time of such nomination or
election or whose election to the Board was recommended or endorsed by at least
a majority of the directors who were Continuing Directors at the time of such
nomination or election; PROVIDED, HOWEVER, that there shall be excluded from
this clause (ii) any individual whose initial assumption of office occurred as a
result of an actual or threatened election contest with respect to the election
or removal of directors or other actual or threatened solicitation of proxies or
consents, by or on behalf of a person other than the Board; or

                                       3

<PAGE>

                      (c) the consummation of a merger, consolidation,
reorganization, recapitalization or statutory share exchange involving the
Company or a sale or other disposition of all or substantially all of the assets
of the Company (a "Business Combination"), unless, immediately following such
Business Combination, each of the following two conditions is satisfied: (i) all
or substantially all of the individuals and entities who were the beneficial
owners of the Outstanding Company Common Stock and Outstanding Company Voting
Securities immediately prior to such Business Combination beneficially own,
directly or indirectly, more than 60% of the then-outstanding shares of common
stock and the combined voting power of the then-outstanding securities entitled
to vote generally in the election of directors, respectively, of the resulting
or acquiring corporation in such Business Combination (which shall include,
without limitation, a corporation which as a result of such transaction owns the
Company or substantially all of the Company's assets either directly or through
one or more subsidiaries) (such resulting or acquiring corporation is referred
to herein as the "Acquiring Corporation") in substantially the same proportions
as their ownership, immediately prior to such Business Combination, of the
Outstanding Company Common Stock and Outstanding Company Voting Securities,
respectively; and (ii) no Person (excluding the Acquiring Corporation or any
employee benefit plan (or related trust) maintained or sponsored by the Company
or by the Acquiring Corporation) beneficially owns, directly or indirectly, 20%
or more of the then outstanding shares of common stock of the Acquiring
Corporation, or of the combined voting power of the then-outstanding securities
of such corporation entitled to vote generally in the election of directors
(except to the extent that such ownership existed prior to the Business
Combination); or

                      (d) approval by the stockholders of the Company of a
complete liquidation or dissolution of the Company.

                  1.2 "CHANGE IN CONTROL DATE" means the first date during the
Term (as defined in Section 2) on which a Change in Control occurs. Anything in
this Agreement to the contrary notwithstanding, if (a) a Change in Control
occurs, (b) the Executive's employment with the Company is terminated prior to
the date on which the Change in Control occurs, and (c) it is reasonably
demonstrated by the Executive that such termination of employment (i) was at the
request of a third party who has taken steps reasonably calculated to effect a
Change in Control or (ii) otherwise arose in connection with or in anticipation
of a Change in Control, then for all purposes of this Agreement

                                       4

<PAGE>

the "Change in Control Date" shall mean the date immediately prior to the date
of such termination of employment.

                  1.3 "CAUSE" means:

                      (a) the Executive's willful and continued failure
substantially to perform his reasonable assigned duties as an officer of the
Company (other than any such failure resulting from incapacity due to physical
or mental illness or any failure after the Executive gives notice of termination
for Good Reason), which failure is not cured within 30 days after a written
demand for substantial performance is received by the Executive from the Board
of Directors of the Company which specifically identifies the manner in which
the Board of Directors believes the Executive has not substantially performed
the Executive's duties; or

                      (b) the Executive's willful engagement in illegal
conduct or gross misconduct which is materially and demonstrably injurious to
the Company.

         For purposes of this Section 1.3, no act or failure to act by the
Executive shall be considered "willful" unless it is done, or omitted to be
done, in bad faith and without reasonable belief that the Executive's action or
omission was in the best interests of the Company.

                  1.4 "GOOD REASON" means the occurrence, without the
Executive's written consent, of any of the events or circumstances set forth in
clauses (a) through (g) below. Notwithstanding the occurrence of any such event
or circumstance, such occurrence shall not be deemed to constitute Good Reason
if, prior to the Date of Termination specified in the Notice of Termination
(each as defined in Section 3.2(a)) given by the Executive in respect thereof,
such event or circumstance has been fully corrected and the Executive has been
reasonably compensated for any losses or damages resulting therefrom (provided
that such right of correction by the Company shall only apply to the first
Notice of Termination for Good Reason given by the Executive).

                      (a) the assignment to the Executive of duties
inconsistent in any material respect with the Executive's position (including
status, offices, titles and reporting requirements), authority or
responsibilities in effect immediately prior to the earliest to occur of (i) the
Change in Control Date, (ii) the date of the execution by the Company of the
initial written agreement or instrument providing for the Change in

                                       5

<PAGE>

Control or (iii) the date of the adoption by the Board of Directors of a
resolution providing for the Change in Control (with the earliest to occur of
such dates referred to herein as the "Measurement Date"), or any other action or
omission by the Company which results in a diminution in such position,
authority or responsibilities;

                      (b) a reduction in the Executive's annual base salary
as in effect on the Measurement Date or as the same was or may be increased from
time to time;

                      (c) the failure by the Company to (i) continue in
effect any material compensation or benefit plan or program (including without
limitation any life insurance, medical, health and accident or disability plan
and any vacation program or policy) (a "Benefit Plan") in which the Executive
participates or which is applicable to the Executive immediately prior to the
Measurement Date, unless an equitable arrangement (embodied in an ongoing
substitute or alternative plan) has been made with respect to such plan or
program, (ii) continue the Executive's participation therein (or in such
substitute or alternative plan) on a basis not materially less favorable, both
in terms of the amount of benefits provided and the level of the Executive's
participation relative to other participants, than the basis existing
immediately prior to the Measurement Date or (iii) award cash bonuses to the
Executive in amounts and in a manner substantially consistent with past practice
in light of the Company's financial performance;

                      (d) a change by the Company in the location at which
the Executive performs his principal duties for the Company to a new location
that is both (i) outside a radius of 35 miles from the Executive's principal
residence immediately prior to the Measurement Date and (ii) more than 20 miles
from the location at which the Executive performed his principal duties for the
Company immediately prior to the Measurement Date; or a requirement by the
Company that the Executive travel on Company business to a substantially greater
extent than required immediately prior to the Measurement Date;

                      (e) the  failure of the Company to obtain the
agreement, in a form reasonably satisfactory to the Executive, from any
successor to the Company to assume and agree to perform this Agreement, as
required by Section 6.1;

                      (f) a purported  termination of the Executive's
employment which is not effected pursuant to a Notice of Termination satisfying
the requirements of

                                       6

<PAGE>

Section 3.2(a), which purported termination shall not be effective for purposes
of this Agreement; or

                      (g) any failure of the Company to pay or provide to
the Executive any portion of the Executive's compensation or benefits due under
any Benefit Plan within seven days of the date such compensation or benefits are
due, or any material breach by the Company of any employment agreement with the
Executive.

         In addition, the termination of employment by the Executive for any
reason or no reason during the 30-day period beginning on the first anniversary
of the Change in Control Date shall be deemed to be termination for Good Reason
for all purposes under this Agreement.

         For purposes of this Agreement, any good faith determination of "Good
Reason" made by the Executive shall be conclusive, binding and final. The
Executive's right to terminate his employment for Good Reason shall not be
affected by his incapacity due to physical or mental illness.

                  1.5 "DISABILITY" means the Executive's absence from the
full-time performance of the Executive's duties with the Company for 180
consecutive calendar days as a result of incapacity due to mental or physical
illness which is determined to be total and permanent by a physician selected by
the Company or its insurers and acceptable to the Executive or the Executive's
legal representative.

         2. TERM OF AGREEMENT. This Agreement, and all rights and obligations of
the parties hereunder, shall take effect upon the Effective Date and shall
expire upon the first to occur of (a) the expiration of the Term (as defined
below) if a Change in Control has not occurred during the Term, (b) the date 24
months after the Change in Control Date, if the Executive is still employed by
the Company as of such later date, or (c) the fulfillment by the Company of all
of its obligations under Sections 4 and 5.2 and 5.3 if the Executive's
employment with the Company terminates within 24 months following the Change in
Control Date. "Term" shall mean the period commencing as of the Effective Date
and continuing in effect through March 31, 2001; PROVIDED, however, that
commencing on April 1, 2001 and each April 1 thereafter, the Term shall be
automatically extended for one additional year unless, not later than 90 days
prior to the scheduled expiration of the Term (or any extension thereof), the
Company shall have given the Executive written notice that the Term will not be
extended.

         3. EMPLOYMENT STATUS; TERMINATION FOLLOWING CHANGE IN CONTROL.

            3.1 NOT AN EMPLOYMENT CONTRACT. The Executive acknowledges
that this Agreement does not constitute a contract of employment or impose on
the Company any obligation to retain the Executive as an employee and that this
Agreement does not prevent the Executive from terminating employment at any
time. If the Executive's employment with the Company terminates for any reason
and subsequently a Change in Control shall occur, the Executive shall not be
entitled to any benefits hereunder except as otherwise provided pursuant to
Section 1.2.

            3.2 TERMINATION OF EMPLOYMENT.

                (a) If the Change in Control Date occurs during
the Term, any termination of the Executive's employment by the Company or by the
Executive within 24 months following the Change in Control Date (other than due
to the death of the Executive) shall be communicated by a written notice to the
other party hereto (the "Notice of Termination"), given in accordance with
Section 7. Any Notice of Termination shall: (i) indicate the specific
termination provision (if any) of this Agreement relied upon by the party giving
such notice, (ii) to the extent applicable, set forth in reasonable detail the
facts and circumstances claimed to provide a basis for termination of the
Executive's employment under the provision so indicated and (iii) specify the
Date of Termination (as defined below). The effective date of an employment
termination (the "Date of Termination") shall be the close of business on the
date specified in the Notice of Termination (which date may not be less than 15
days or more than 120 days after the date of delivery of such Notice of
Termination), in the case of a termination other than one due to the Executive's
death, or the date of the Executive's death, as the case may be.

                (b) The failure by the Executive or the Company to set forth
in the Notice of Termination any fact or circumstance which contributes to a
showing of Good Reason or Cause shall not waive any right of the Executive
or the Company, respectively, hereunder or preclude the Executive or the
Company, respectively, from asserting any such fact or circumstance in
enforcing the Executive's or the Company's right hereunder.

                (c) Any  Notice of Termination for Cause given
by the Company must be given within 90 days of the occurrence of the event(s) or
circumstance(s) which constitute(s) Cause. Prior to any Notice of Termination
for Cause being given (and

                                       8

<PAGE>

prior to any termination for Cause being effective), the Executive shall be
entitled to a hearing before the Board of Directors of the Company at which he
may, at his election, be represented by counsel and at which he shall have a
reasonable opportunity to be heard. Such hearing shall be held on not less than
15 days prior written notice to the Executive stating the Board of Directors'
intention to terminate the Executive for Cause and stating in detail the
particular event(s) or circumstance(s) which the Board of Directors believes
constitutes Cause for termination. Any such Notice of Termination for Cause must
be approved by an affirmative vote of two-thirds of the members of the Board of
Directors.

                (d)      Any Notice of Termination for Good Reason
given by the Executive must be given within 90 days of the occurrence of the
event(s) or circumstance(s) which constitute(s) Good Reason.

         4. BENEFITS TO EXECUTIVE.

            4.1 STOCK ACCELERATION. If the Change in Control Date occurs
during the Term, then, effective upon the Change in Control Date, (a) each
outstanding option to purchase shares of Common Stock of the Company held by the
Executive, not otherwise fully exercisable or automatically exercisable in full
upon a Change in Control, shall become immediately exercisable in full, (b) each
outstanding restricted stock award shall be deemed to be fully vested and no
longer subject to a right of repurchase by the Company and (c) notwithstanding
any provision in any applicable option agreement to the contrary, each such
option shall continue to be exercisable by the Executive (to the extent such
option was exercisable on the Date of Termination) for a period of six months
following the Date of Termination.

            4.2 COMPENSATION. If the Change in Control Date occurs during
the Term and the Executive's employment with the Company terminates within 24
months following the Change in Control Date, the Executive shall be entitled to
the following benefits:

                (a) TERMINATION WITHOUT CAUSE OR FOR GOOD REASON.
If the Executive's employment with the Company is terminated by the Company
(other than for Cause, Disability or Death) or by the Executive for Good Reason
within 24 months following the Change in Control Date, then the Executive shall
be entitled to the following benefits:

                                       9

<PAGE>

                                   (i) the Company shall pay to the
Executive in a lump sum in cash within 30 days after the Date of Termination the
aggregate of the following amounts:

                                       (1) the sum of (A) the Executive's base
salary through the Date of Termination, (B) the product of (x) the annual
bonus paid or payable (including any bonus or portion thereof which has
been earned but deferred) for the most recently completed fiscal year and
(y) a fraction, the numerator of which is the number of days in the current
fiscal year through the Date of Termination, and the denominator of which is 365
and (C) the amount of any compensation previously deferred by the Executive
(together with any accrued interest or earnings thereon) and any accrued
vacation or compensatory time off pay, in each case to the extent not previously
paid (the sum of the amounts described in clauses (A), (B), and (C) shall be
hereinafter referred to as the "Accrued Obligations"); and

                                       (2) the amount equal to (A) two
and one-half multiplied by (B) the sum of (x) the Executive's highest annual
base salary from the Company during the five-year period prior to the Change in
Control Date and (y) the Executive's highest annual bonus from the Company
during the five-year period prior to the Change in Control Date.

                                    (ii) for 30 months after the Date of
Termination, or such longer period as may be provided by the terms of the
appropriate plan, program, practice or policy, the Company shall continue to
provide benefits to the Executive and the Executive's family at least equal to
those which would have been provided to them if the Executive's employment had
not been terminated, in accordance with the applicable Benefit Plans in effect
on the Measurement Date or, if more favorable to the Executive and his family,
in effect generally at any time thereafter with respect to other peer executives
of the Company and its affiliated companies; PROVIDED, however, that if the
Executive becomes reemployed with another employer and is eligible to receive a
particular type of benefits (e.g., health insurance benefits) from such employer
on terms at least as favorable to the Executive and his family as those being
provided by the Company, then the Company shall no longer be required to provide
those particular benefits to the Executive and his family;

                                    (iii) to the extent not previously paid or
provided, the Company shall timely pay or provide to the Executive outplacement
assistance commensurate with the Executive's position as well as any other
amounts or benefits

                                       10

<PAGE>

required to be paid or provided or which the Executive is eligible to receive
following the Executive's termination of employment under any plan, program,
policy, practice, contract or agreement of the Company and its affiliated
companies (such other amounts and benefits shall be hereinafter referred to as
the "Other Benefits"); and

                                    (iv) for purposes of determining eligibility
(but not the time of commencement of benefits) of the Executive for retiree
benefits to which the Executive is entitled, the Executive shall be considered
to have remained employed by the Company until 30 months after the Date of
Termination.

                           (b) RESIGNATION WITHOUT GOOD REASON; TERMINATION
FOR DEATH OR DISABILITY. If the Executive voluntarily terminates his employment
with the Company within 24 months following the Change in Control Date,
excluding a termination for Good Reason, or if the Executive's employment with
the Company is terminated by reason of the Executive's death or Disability
within 24 months following the Change in Control Date, then the Company shall
(i) pay the Executive (or his estate, if applicable), in a lump sum in cash
within 30 days after the Date of Termination, the Accrued Obligations and (ii)
timely pay or provide to the Executive the Other Benefits.

                           (c) TERMINATION FOR CAUSE. If the Company terminates
the Executive's employment with the Company for Cause within 24 months following
the Change in Control Date, then the Company shall (i) pay the Executive, in a
lump sum in cash within 30 days after the Date of Termination, the sum of (A)
the Executive's annual base salary through the Date of Termination and (B) the
amount of any compensation previously deferred by the Executive, in each case to
the extent not previously paid, and (ii) timely pay or provide to the Executive
the Other Benefits.

                  4.3 TAXES.

                      (a) In the event that the Company undergoes a
"Change in Ownership or Control" (as defined below), the Company shall, within
30 days after each date on which the Executive becomes entitled to receive
(whether or not then due) a Contingent Compensation Payment (as defined below)
relating to such Change in Ownership or Control, determine and notify the
Executive (with reasonable detail regarding the basis for its determinations)
(i) which of the payments or benefits due to the Executive (under this Agreement
or otherwise) following such Change in Ownership or Control constitute
Contingent Compensation Payments, (ii) the amount, if any, of the excise tax
(the "Excise Tax") payable pursuant to Section 4999 of the Internal Revenue Code
of 1986, as amended (the "Code"), by the Executive with respect to such
Contingent Compensation Payment and (iii) the amount of the Gross-Up Payment (as
defined below) due to the Executive with respect to such Contingent Compensation
Payment. Within 30 days after delivery of such notice to the Executive, the
Executive shall deliver a response to the Company (the "Executive Response")
stating either (A) that he agrees with the Company's determination pursuant to
the preceding sentence or (B) that he disagrees with such determination, in
which case he shall indicate which payment and/or benefits should be
characterized as a Contingent Compensation Payment, the amount of the Excise Tax
with respect to such Contingent Compensation Payment and the amount of the
Gross-Up Payment due to the Executive with respect to such Contingent
Compensation Payment. The amount and characterization of any item in the
Executive Response shall be final; provided, however, that in the event that the
Executive fails to deliver an Executive Response on or before the required date,
the Company's initial determination shall be final. Within 90 days after the due
date of each Contingent Compensation Payment to the Executive, the Company shall
pay to the Executive, in cash, the Gross-Up Payment with respect to such
Contingent Compensation Payment, in the amount determined pursuant to this
Section 4.3(a).

                      (b) For purposes of this Section 4.3, the following
terms shall have the following respective meanings:

                          (i) "Change in Ownership or Control" shall mean
a change in the ownership or effective control of the Company or in
the ownership of a substantial portion of the assets of the Company determined
in accordance with Section 280G(b)(2) of the Code.

                                       12

<PAGE>

                          (ii) "Contingent Compensation Payment" shall
mean any payment (or benefit) in the nature of compensation that is made or
supplied (under this Agreement or otherwise) to a "disqualified individual" (as
defined in Section 280G(c) of the Code) and that is contingent (within the
meaning of Section 280G(b)(2)(A)(i) of the Code) on a Change in Ownership or
Control of the Company.

                          (iii) "Gross-Up Payment" shall mean an amount
equal to the sum of (i) the amount of the Excise Tax payable with respect
to a Contingent Compensation Payment and (ii) the amount necessary to pay all
additional taxes imposed on (or economically borne by) the Executive (including
the Excise Taxes, state and federal income taxes and all applicable withholding
taxes) attributable to the receipt of such Gross-Up Payment. For purposes of the
preceding sentence, all taxes attributable to the receipt of the Gross-Up
Payment shall be computed assuming the application of the maximum tax rates
provided by law.

            4.4 MITIGATION. The Executive shall not be required to
mitigate the amount of any payment or benefits provided for in this Section 4 by
seeking other employment or otherwise. Further, except as provided in Section
4.2(a)(ii), the amount of any payment or benefits provided for in this Section 4
shall not be reduced by any compensation earned by the Executive as a result of
employment by another employer, by retirement benefits, by offset against any
amount claimed to be owed by the Executive to the Company or otherwise.

         5. DISPUTES.

            5.1 SETTLEMENT OF DISPUTES; ARBITRATION. All claims by the
Executive for benefits under this Agreement shall be directed to and determined
by the Board of Directors of the Company and shall be in writing. Any denial by
the Board of Directors of a claim for benefits under this Agreement shall be
delivered to the Executive in writing and shall set forth the specific reasons
for the denial and the specific provisions of this Agreement relied upon. The
Board of Directors shall afford a reasonable opportunity to the Executive for a
review of the decision denying a claim. Any further dispute or controversy
arising under or in connection with this Agreement shall be settled exclusively
by arbitration in Boston, Massachusetts, in accordance with the rules of the
American Arbitration Association then in effect. Judgment may be entered on the
arbitrator's award in any court having jurisdiction.

            5.2 EXPENSES. The Company agrees to pay as incurred, to the
full extent permitted by law, all legal, accounting and other fees and expenses
which the Executive may reasonably incur as a result of any claim or contest
(regardless of the outcome thereof) by the Company, the Executive or others
regarding the validity or enforceability of, or liability under, any provision
of this Agreement or any guarantee of performance thereof (including as a result
of any contest by the Executive regarding the amount of any payment or benefits
pursuant to this Agreement), plus in each case interest on any delayed payment
at the applicable Federal rate provided for in Section 7872(f)(2)(A) of the
Code.

            5.3 COMPENSATION DURING A DISPUTE. If the Change in Control
Date occurs during the Term and the Executive's employment with the Company
terminates within 24 months following the Change in Control Date, and the right
of the Executive to receive benefits under Section 4 (or the amount or nature of
the benefits to which [he is entitled to receive) are the subject of a dispute
between the Company and the Executive, the Company shall continue (a) to pay to
the Executive his base salary in effect as of the Measurement Date and (b) to
provide benefits to the Executive and the Executive's family at least equal to
those which would have been provided to them, if the Executive's employment had
not been terminated, in accordance with the applicable Benefit Plans in effect
on the Measurement Date, until such dispute is resolved either by mutual written
agreement of the parties or by an arbitrator's award pursuant to Section 5.1.
Following the resolution of such dispute, the sum of the payments made to the
Executive under clause (a) of this Section 5.3 shall be deducted from any cash
payment which the Executive is entitled to receive pursuant to Section 4; and if
such sum exceeds the amount of the cash payment which the Executive is entitled
to receive pursuant to Section 4, the excess of such sum over the amount of such
payment shall be repaid (without interest) by the Executive to the Company
within 60 days of the resolution of such dispute.

         6. SUCCESSORS.

            6.1 SUCCESSOR TO COMPANY. The Company shall require any
successor (whether direct or indirect, by purchase, merger, consolidation or
otherwise) to all or substantially all of the business or assets of the Company
expressly to assume and agree to perform this Agreement to the same extent that
the Company would be required to perform it if no such succession had taken
place. Failure of the Company to obtain an assumption of this Agreement at or
prior to the effectiveness of any succession shall be a breach of this Agreement
and shall constitute Good Reason if the Executive elects to terminate
employment, except that for purposes of implementing the foregoing, the date on
which any such succession becomes effective shall be deemed the Date of
Termination. As used in this Agreement, "Company" shall mean the Company as
defined above and any successor to its business or assets as aforesaid which
assumes and agrees to perform this Agreement, by operation of law or otherwise.

            6.2 SUCCESSOR TO EXECUTIVE. This Agreement shall inure to the
benefit of and be enforceable by the Executive's personal or legal
representatives, executors, administrators, successors, heirs, distributees,
devisees and legatees. If the Executive should die while any amount would still
be payable to the Executive or his family hereunder if the Executive had
continued to live, all such amounts, unless otherwise provided herein, shall be
paid in accordance with the terms of this Agreement to the executors, personal
representatives or administrators of the Executive's estate.

         7. NOTICE. All notices, instructions and other communications given
hereunder or in connection herewith shall be in writing. Any such notice,

mail, return receipt requested, postage prepaid, or (ii) prepaid via a reputable
nationwide overnight courier service, in each case addressed to the Company, at
7 Lopez Road, Wilmington, Massachusetts 01887, and to the Executive at 104
Granville Ave., Malden, MA 02148 (or to such other address as either the Company
or the Executive may have furnished to the other in writing in accordance
herewith). Any such notice, instruction or communication shall be deemed to have
been delivered five business days after it is sent by registered or certified
mail, return receipt requested, postage prepaid, or one business day after it is
sent via a reputable nationwide overnight courier service. Either party may give
any notice, instruction or other communication hereunder using any other means,
but no such notice, instruction or other communication shall be deemed to

                                       15

have been duly delivered unless and until it actually is received by the party
for whom it is intended.

         8. MISCELLANEOUS.

            8.1 EMPLOYMENT BY SUBSIDIARY. For purposes of this Agreement, the
Executive's employment with the Company shall not be deemed to have
terminated solely as a result of the Executive continuing to be employed by a
wholly-owned subsidiary of the Company.

            8.2 SEVERABILITY. The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or enforceability
of any other provision of this Agreement, which shall remain in full force
and effect.

            8.3 INJUNCTIVE RELIEF. The Company and the Executive agree that
any breach of this Agreement by the Company is likely to cause the Executive
substantial and irrevocable damage and therefore, in the event of any such
breach, in addition to such other remedies which may be available, the
Executive shall have the right to specific performance and injunctive relief.

            8.4 GOVERNING LAW. The validity, interpretation, construction and
performance of this Agreement shall be governed by the internal laws of the
Commonwealth of Massachusetts, without regard to conflicts of law principles.

            8.5 WAIVERS. No waiver by the Executive at any time of any breach
of, or compliance with, any provision of this Agreement to be performed by
the Company shall be deemed a waiver of that or any other provision at any
subsequent time.

            8.6 COUNTERPARTS. This Agreement may be executed in
counterparts, each of which shall be deemed to be an original but both of which
together shall constitute one and the same instrument.

            8.7 TAX WITHHOLDING. Any payments provided for hereunder shall be
paid net of any applicable tax withholding required under federal, state or
local law.

            8.8 ENTIRE AGREEMENT. This Agreement sets forth the entire
agreement of the parties hereto in respect of the subject matter contained
herein and supersedes all prior agreements, promises, covenants,
arrangements, communications, representations

                                       16

or warranties, whether oral or written, by any officer, employee or
representative of any party hereto; and any prior agreement of the parties
hereto in respect of the subject matter contained herein is hereby terminated
and cancelled.

                  8.9 AMENDMENTS. This Agreement may be amended or modified only
by a written instrument executed by both the Company and the Executive.

                  IN WITNESS WHEREOF, the parties hereto have executed this

         The following terms and conditions are applicable with respect to this
option agreement, and your signature below shall constitute your acknowledgment
and acceptance of same.

<PAGE>

1.       GRANT OF OPTION.

         This agreement evidences the grant by the Company, on ______________
(the "Grant Date") to you (the "Participant"), of an option to purchase, in
whole or in part, on the terms provided herein and in the Company's 1994 Stock
Option Plan, as amended (the "Plan"), a total number of shares (the "Shares") of
common stock, $.01 par value per share, of the Company ("Common Stock") at
$_____ per Share (the option grant(s) set forth above shall be referred to
herein as a "Option"). Unless earlier terminated, this option shall expire on
the date set forth above (the "Final Exercise Date").

         It is intended that the option evidenced by this agreement shall be an
incentive stock option as defined in Section 422 of the Internal Revenue Code of
1986, as amended and any regulations promulgated thereunder (the "Code"). Except
as otherwise indicated by the context, the term "Participant," as used in this
option, shall be deemed to include any person who acquires the right to exercise
this option validly under its terms.

2.       VESTING SCHEDULE.

         This Option will become exercisable ("vest") as to 33 1/3% of the
original number of Shares on the first anniversary of the Grant Date applicable
to such option and as to an additional 33 1/3% of the original number of Shares
upon each of the following two anniversaries of such Grant Date, respectively.

         The right of exercise shall be cumulative so that to the extent an
Option is not exercised in any period to the maximum extent permissible it shall
continue to be exercisable, in whole or in part, with respect to all shares for
which it is vested until the earlier of the Final Exercise Date applicable to
such option or the termination of such option under Section 3 hereof or the
Plan.

3.       EXERCISE OF OPTION.

         (a) FORM OF EXERCISE. Each election to exercise this option shall be in
writing, signed by the Participant, and received by the Company at its principal
office, accompanied by this agreement, and payment in full in the manner
provided in the Plan. The Participant may purchase less than the number of
shares covered hereby, provided that no partial exercise of this option may be
for any fractional share or for fewer than one hundred (100) whole shares.

         (b) CONTINUOUS RELATIONSHIP WITH THE COMPANY REQUIRED. Except as
otherwise provided in this Section 3, this option may not be exercised unless
the Participant, at the time he or she exercises this option, is, and has been
at all times since

                                                                               2
<PAGE>

the Grant Date, an employee, officer or employee director of, the Company or any
parent or subsidiary of the Company as defined in Section 424(e) or (f) of the
Code (an "Eligible Participant").

         (c) TERMINATION OF RELATIONSHIP WITH THE COMPANY. If the Participant
ceases to be an Eligible Participant for any reason, then, except as provided in
paragraphs (d) and (e) below, the right to exercise this option shall terminate
three months after such cessation (but in no event after the Final Exercise
Date), PROVIDED THAT this option shall be exercisable only to the extent that
the Participant was entitled to exercise this option on the date of such
cessation. Notwithstanding the foregoing, if the Participant, prior to the Final
Exercise Date, violates the non-competition or confidentiality provisions of any
employment contract, confidentiality and nondisclosure agreement or other
agreement between the Participant and the Company, the right to exercise this
option shall terminate immediately upon written notice to the Participant from
the Company describing such violation.

         (d) EXERCISE PERIOD UPON DEATH OR DISABILITY. If the Participant dies
or becomes disabled (within the meaning of Section 22(e)(3) of the Code) prior
to the Final Exercise Date while he or she is an Eligible Participant and the
Company has not terminated such relationship for "cause" as specified in
paragraph (e) below, this option shall be exercisable, within the period of one
year following the date of death or disability of the Participant by the
Participant, PROVIDED THAT this option shall be exercisable only to the extent
that this option was exercisable by the Participant on the date of his or her
death or disability, and further provided that this option shall not be
exercisable after the Final Exercise Date.

         (e) DISCHARGE FOR CAUSE. If the Participant, prior to the Final
Exercise Date, is discharged by the Company for "cause" (as defined below), the
right to exercise this option shall terminate immediately upon the effective
date of such discharge. "Cause" shall mean willful misconduct by the Participant
or willful failure by the Participant to perform his or her responsibilities to
the Company (including, without limitation, breach by the Participant of any
provision of any employment, consulting, advisory, nondisclosure,
non-competition or other similar agreement between the Participant and the
Company), as determined by the Company, which determination shall be conclusive.
The Participant shall be considered to have been discharged for "Cause" if the
Company determines, within 30 days after the Participant's resignation, that
discharge for cause was warranted.

                                                                               3
<PAGE>

4.       WITHHOLDING.

         No Shares will be issued pursuant to the exercise of this option unless
and until the Participant pays to the Company, or makes provision satisfactory
to the Company for payment of, any federal, state or local withholding taxes
required by law to be withheld in respect of this option.

5.       NONTRANSFERABILITY OF OPTION.

         This option may not be transferred otherwise than by will or the laws
of descent and distribution, and, during the lifetime of the Participant, this
option shall be exercisable only by the Participant.

6.       DISQUALIFYING DISPOSITION.

         If the Participant disposes of Shares acquired upon exercise of this
option within two years from the Grant Date or one year after such Shares were
acquired pursuant to exercise of this option, the Participant shall immediately
notify the Company in writing of such disposition. If the Participant has died
before Shares are sold, the above holding restrictions and notice requirement do
not apply.

7.       STOCK SPLITS.

         The shares of Common Stock underlying this option or these options and
the exercise price therefor shall be appropriately adjusted from time to time
for stock splits, reverse splits and stock dividends.

8.       ACQUISITION AND CHANGE IN CONTROL EVENTS

         (a)      DEFINITIONS

                  (i)      An "Acquisition Event" shall mean:

                                    with or into another entity as a result of
                                    which the Common Stock is converted into or
                                    exchanged for the right to receive cash,
                                    securities or other property; or

                           (B)      any exchange of shares of the Company for
                                    cash, securities or other property pursuant
                                    to a statutory share exchange transaction.

                                                                               4

                           exchange involving the Company or a sale or other
                           disposition of all or substantially all of the assets
                           of the Company (a "Business Combination"), unless,
                           immediately following such Business Combination, all
                           or substantially all of the individuals and entities
                           who were the beneficial owners of the
                           then-outstanding shares of Common Stock, (the
                           "Outstanding Company Common Stock") and the
                           then-outstanding Securities of the Company entitled
                           to vote generally on the election of directors (the
                           "Outstanding Company Voting Securities") immediately
                           prior to such Business Combination beneficially own,
                           directly or indirectly, more than 50% of the

                           combined voting power of the then-outstanding
                           securities entitled to vote generally in the election
                           of directors, respectively, of the resulting or
                           acquiring corporation in such Business Combination
                           (which shall include, without limitation, a
                           corporation which as a result of such transaction
                           owns the Company or substantially all of the
                           Company's assets either directly or through one or
                           more subsidiaries) (such resulting or acquiring
                           corporation is referred to herein as the "Acquiring
                           Corporation") in substantially the same proportions
                           as their ownership of the Outstanding Company Common
                           Stock and Outstanding Company Voting Securities,
                           respectively, immediately prior to such Business
                           Combination.

         (b)      EFFECT ON OPTIONS

                  (i)      ACQUISITION EVENT. Upon the occurrence of an
                           Acquisition Event (regardless of whether such event
                           also constitutes a Change in Control Event), or the
                           execution by the Company of any agreement with
                           respect to an Acquisition Event (regardless of
                           whether such event will result in a Change in Control
                           Event), the Board shall provide that all outstanding
                           Options shall be assumed, or equivalent options shall
                           be substituted, by the acquiring or succeeding
                           corporation (or an affiliate thereof); PROVIDED THAT
                           if such Acquisition Event also constitutes a Change
                           in Control Event, such assumed or substituted options
                           shall be immediately exercisable in full upon the
                           occurrence of such Acquisition Event.

                                                                               5
<PAGE>

                           Notwithstanding the foregoing, if the acquiring or
                           succeeding corporation (or an affiliate thereof) does
                           not agree to assume, or substitute for, such Options,
                           then the Board shall, upon written notice to the
                           Participants, provide that all then unexercised
                           Options will become exercisable in full as of a
                           specified time prior to the Acquisition Event and
                           will terminate immediately prior to the consummation
                           of such Acquisition Event, except to the extent
                           exercised by the Participants before the consummation
                           of such Acquisition Event.

                  (ii)     CHANGE IN CONTROL EVENT THAT IS NOT AN ACQUISITION
                           EVENT. Upon the occurrence of a Change in Control
                           Event that does not also constitute an Acquisition
                           Event, all Options then-outstanding shall
                           automatically become immediately exercisable in full.

9.       PROVISIONS OF THE PLAN.

         This Option is subject to the provisions of the Plan, a copy of which
is furnished to the Participant with this option.

         This opportunity to purchase stock in the Company is being offered
because of the Company's desire to reward continuing service. However, it is not
and should not be construed as a guarantee of continuing employment.
Furthermore, exercising options may not be a prudent business decision for some
employees. Therefore, we urge you to review this opportunity carefully, consult
a tax advisor, and make a decision to exercise options only if your personal
financial situation makes this a wise decision.

                                                                               6
<PAGE>
