                  number of shares the  Authority is entitled to purchase  under
                  the Warrant to 200,000 and shall increase the put value of the

                  Agreement and to incur the obligations herein provided for and
                  that all  documents  and  agreements  executed  ant  delivered
                  pursuant hereto, when delivered,  will be valid and binding in
                  accordance  with  their  respective  terms  and  that  it will
                  deliver at closing an opinion  from its counsel  with  respect
                  thereto.

         b.       There has been no  material  adverse  change in the  financial
                  condition of the Borrower and its guarantor(s),  if any, since
                  the date of application for this loan. '

         c.       It will  comply  with the  Affirmative  Action  Policy  of the
                  Authority,  and has  delivered  to the  Authority  within  six
                  months of the date hereof a copy of an Affirmative Action Plan
                  covering  Borrower and any related  guarantors,  if any,  such
                  Affirmative Action Plan to be acceptable to the Authority.

         d.       It has obtained and put into place financing from  Connecticut
                  Innovations  Incorporated  in an amount equal to the amount of
                  the loan.

         5. The  Authority  shall from time to time, in its  discretion,  during
regular  business  hours,  have the  privilege  of making an  inspection  of the
Collateral  and the Borrower  shall assist the Authority in said  inspection and
shall  make  available  such  books  and  other  records  as the  Authority  may
reasonably  request.  The Authority  agree that,  unless  Borrower is in default
hereunder or under any of the  documents  executed in  connection  herewith,  it
shall  keep  confidential  to the  extent  permitted  by  law,  the  proprietary
information regarding Borrower's operations and products in the possession of or
known to the Authority.

         6. This  Agreement  may not be modified or amended in any manner except
in writing executed by all of the parties hereto.

         7. This  Agreement  and any of the  documents  related  hereto  and the
rights  thereunder  may not be  assigned  by the  Borrower  without  the written
consent of the Authority.  In the event that the Authority  receives a bona fide
third  party  offer  (the  "Offer")  to  purchase  this  Agreement  prior to the
termination  hereof and desires to accept such offer,  then the Authority  shall
give notice of such Offer to the Borrower.  The Borrower shall have the right to
purchase this Agreement on the same terms and conditions as are set forth in the
Offer. If the Borrower elects to exercise its rights to purchase this Agreement,
it shall give notice of the same to the Authority within thirty (30) days of the
date of the  Authority's  notice to the  Borrower.  Failure of the  Borrower  to
provide such notice within said thirty (30) days shall terminate the Borrower' 8
right of first refusal with respect to the Offer.

         8. The terms and conditions of the Financing Documents are incorporated
herein, and any breach of said terms and conditions is a breach hereunder, and a
breach hereunder shall be a breach of any of the Financing Documents.

         9. Any  misrepresentation,  breach of warranty  or other  breach of any
agreement or covenant contained in this Agreement shall entitle the Authority to
declare the unpaid balance of the Note due and payable without further notice to
the  Borrower,  or to  exercise  any  remedy  it may have  with  respect  to the
Collateral as set forth in the Financing Documents or otherwise provided by law,
or to exercise any such remedies cumulatively.

         10. Any default under the terms of this  Agreement  shall  constitute a
default under the Note,  the  Financing  Documents,  and any other  documents or
instruments evidencing or securing any other loan now existing or hereafter made
by the  Authority to the Borrower,  and a default under the Note,  the Financing
Documents or such other  documents  or  instruments  shall  constitute a default
under this Agreement.

         11. The security  interest,  liens and other rights and interests in or
relating  to any  of the  real  or  personal  property  of the  Borrower  or its
guarantors, if any, now or hereafter granted to the Authority by the Borrower or
its  guarantors,  if any,  including but not limited to the Security  Agreement,
shall serve as security  for any and all  liabilities  of the  Borrower  and its
guarantors  to the  Authority  including  but  not  limited  to the  liabilities
described  in  this   Agreement  and  the  Note  but  excluding  the  Borrower's
obligations under the Warrant and, for the repayment thereof,  the Authority may
resort to any security held by it in such order and manner as it may elect.

         12.  Any event of  default  under  this  Agreement  shall  entitle  the
Authority,  at its sole discretion,  to demand immediate and full payment of the
principal on the Note,  together with accrued interest,  remaining unpaid at the
time of such event of default.

         13. The Borrower  shall  provide the  Authority  with an opinion of its
counsel that the Borrower in  substantially  the same form as Exhibit B attached
hereto and made a part hereof.

         14. This Agreement shall terminate upon payment in full of the loan.
