IV.  Events of Default
     -----------------

     A. Notwithstanding any other provision to the contrary, this Note shall
become and be due and payable in its entirety within 45 days after receipt of

herein called "events of default," shall happen and be continuing for a period

any other legal or equitable rights as such Payee.

V.   Miscellaneous
     -------------

     A. All agreements between the Company and Payee expressly are limited so
that in no event whatsoever shall the amount paid or agreed to be paid by the
Company to Payee hereunder exceed the higher lawful contractual rate of interest
permissible under the law which a court of competent jurisdiction, by a final
order which is not appealed or is nonappealable, determines is applicable to
this Note. If fulfillment of any provision of this Note at the time performance
of such provision becomes due involves exceeding such highest lawful contractual
rate, then such obligation shall be reduced to such highest lawful contractual
rate. If by any circumstance Payee shall ever receive as interest an amount
which exceeds such highest lawful contractual rate, any amount which may be
deemed excessive interest shall be applied as payment of the principal of the
indebtedness evidenced hereby and not as payment of interest. The terms and
provisions of this paragraph shall control all other terms and provisions
contained in this Note.

     B. The Payee acknowledges and represents that the Company has been induced
to execute this Note based upon certain representations, covenants, and
statements made by the Payee in an Agreement for Purchase and Sale of Assets of
even date herewith and that the terms, representations, statements, and
acknowledgements of the Payee therein are incorporated in this Note.

     C. If any provision hereof is for any reason and to any extent invalid or
unenforceable, the remainder of this Note shall not be affected thereby, but
instead shall be enforceable to the maximum extent permitted by law.

                                                                          104

     D.  This Note may not be terminated or amended orally, but only by a 
termination or amendment in writing signed by both parties hereto.

     E.  This Note shall be construed and enforced in accordance with the laws
of the Commonwealth of Massachusetts without regard to its conflict of law
provisions.

     F.  All notices required or permitted under this Note shall be in writing
and shall be effective upon receipt thereof.

     G.  No recourse shall be had for the payment of the principal or
interest of this Note against any incorporator or any past, present or future
stockholder, officer, director or agent of the Company or of any successor
corporation, either directly or through the Company or any successor
corporation, under any statute or by the enforcement of any assessment or
otherwise, all such liability of the incorporators, stockholders, officers,
directors and agents being waived, released and surrendered by the holder
hereof by the acceptance of this Note.
