or at such other place as Holder may designate from time to time in writing, the
principal sum of Fifty Thousand Dollars ($50,000), together with: (i) interest
on the unpaid principal balance of this Note, from the date hereof until said
balance shall have been paid in full, at the rate of three percent (3%) per annum;
(ii) all costs and expenses, including reasonable attorneys' fees, incurred in
collecting or attempting to collect the indebtedness evidenced by this Note or
in any litigation or controversy arising from or connected with this Note; and
(iii) all taxes or duties assessed upon the indebtedness evidenced by this Note.
All amounts owing under this Note shall be payable in legal tender of the United
States of America. 



The principal amount hereof will be payable on demand on or after ninety (90)
days following the date hereof. 



Interest shall accrue and be payable at maturity. 



Any payment under this Note which is stated to be due on a day other than a "Business
Day" (a day on which banks are legally required to be open for business in Waterbury,
Connecticut) shall be made on the next succeeding Business Day, and any such extension
of time shall be included in the computation of the amount of interest to be paid.




This Note may be prepaid at any time, in whole or in part, without prepayment
penalty or premium. 



The following shall constitute Events of Default hereunder (i) in the event Maker
shall fail to pay any installment of principal or interest within ten (10) days
following the due date hereof, (ii) in the event of the dissolution, termination
of existence, insolvency (failure to pay its debts as they mature or where the
fair market value of its assets is not in excess of its liabilities), business
failure, appointment of a receiver, trustee, custodian or similar fiduciary, assignment
for the benefit of creditors or the commencement of any proceedings under any
bankruptcy laws by or against the Maker and the continuation of such proceeding

the Holder, in addition to any and all other sums and charges due, the entire
principal of and interest accrued on this Note. 



Any failure by the Holder to exercise any right under this, or any delay in such
exercise, shall not constitute a waiver of the right to exercise such right at
a later time so long as such Event of Default shall remain uncured, and shall
not constitute a waiver of the right to exercise such right if any other Event
of Default shall occur. The acceptance by Holder of payment of any sum payable
under this Note after the due date of such payment shall not be a waiver of Holder's
right to require prompt payment when due of all other sums payable under this
Note. 



If any one or more of the provisions of this Note shall for any reason be held
to be invalid, illegal or unenforceable, in whole or in part, or in any respect,
or if any one or more of the provisions of this Note shall operate, or would prospectively
operate, to invalidate this Note, then such provision or provisions only shall
be deemed to be null and void and of no force or effect and shall not affect any
other provision of this Note, and the remaining provisions of this Note shall
remain operative and in full force and effect, shall be valid, legal and enforceable,
and shall in no way be affected: prejudiced or disturbed thereby.



This Note may not be modified or terminated orally, but only by a written instrument
signed by the party against whom enforcement of any such modification or termination
is sought. Time is and shall be of the essence in the performance of all obligations
under this Note. This Note shall be governed by and construed in accordance with
the laws of the State of Connecticut.
