          1.  That he is the  president  of  Medical  Sterilization,  Inc.,  the

affidavit on behalf of the corporate defendant and has the power to execute this
Affidavit of Confession of Judgment on behalf of the defendant.


          2. That he resides at 8 Hunters Lane, Roslyn, New York 11576.

          3.  Subject to the  provisions  of paragraph 5 that  defendant  hereby
confesses  judgment  herein  in  favor  of  Shamrock  Technologies,   Inc.,  the
above-named plaintiff, for the sum of $1,250,000, and hereby authorizes entry of
judgment in favor of plaintiff against defendant for that sum.


          4. That defendant authorizes entry of judgment in New York County, New
York, if said residence address is not in New York State.


          5. That this confession of judgment is to secure the plaintiff against
all  liability  arising upon the  following  facts:  Plaintiff and defendant and
other parties have entered into a settlement  agreement dated September 14, 1994
and various related agreements pursuant to which, among other things, a judgment
of the United States District Court for the Eastern District of New York entered
in favor of  plaintiff  and against  defendant  in the amount of  $2,677,728.70,
together with interest on the sum of $2,057,294.30 at the rate of 1.5% above the

Confession of Judgment is executed in order to secure the plaintiff  against the
contingent  liability in the amount of  $1,250,000  which will become due in the
event  the  settlement  agreement  is  rejected  under  the  provisions  of  the
Bankruptcy Code or otherwise terminated,  amended or modified in a proceeding in
which Medical  Sterilization,  Inc. is the debtor.  The sum  confessed  does not
exceed the amount of the contingent liability.

          This  affidavit,  if made in  connection  with  an  agreement  for the
purchase  of  $1,500.00  or less of any  commodities  for any use  other  than a
commercial or business use upon any plan of deferred  payments whereby the price
or cost is payable in two or more installments,  was executed  subsequent to the
time a default occurred in the payment of an installment thereunder.
