                        such installments to become due on the same day of  each
                        succeeding calendar month through July 1, 2005, when the
                        Borrower shall repay the outstanding principal amount of
                        Loan III to the Bank and pay to the  Bank  all  interest

                        to the Bank in advance in full or in part  at  any  time
                        and from time to time; provided, however,  that (i)  the
                        amount  of any  such  repayment  in  part  shall  be  an
                        integral multiple of $50,000 and (ii)  upon  making  any
                        such repayment in full the  Borrower shall  pay  to  the

                        remaining unpaid.  Each such repayment in part  shall be
                        applied to the installments of the principal  amoun t of
                        Loan III  in  the  inverse  order of  such  installments
                        becoming due.




                  e.    INTEREST.  From and including the date Loan III is  made

                        to but not including the date the outstanding  principal
                        amount of Loan III is repaid in full, the Borrower shall
                        pay to the Bank  interest,  calculated on the basis of a
                        360-day year for the actual number of days of each  year
                        (365 or  366,  as  applicable),  on  such    outstanding
                        principal amount at a  rate  per year  that shall (i) on
                        each day  beginning  before  the  maturity,   whether by
                        acceleration or otherwise, of such outstanding principal
                        amount be  the  rate  in effect  such  day as the Bank's
                        Prime Rate and (ii) on each day  subsequent to the  last
                        day described in clause (i) of this sentence be 3% above
                        the rate in effect such  subsequent  day  as  the Bank's
                        Prime Rate;  provided,  however,  that (A) in  no  event
                        shall such  interest be payable at a rate in  excess  of
                        the maximum rate  permitted  by  applicable  law and (B)
                        solely  to the extent  necessary  to   result  in   such
                        interest  not  being payable at a rate in excess of such
                        maximum rate, any amount that would be  treated  as part
                        of such interest under a final  judicial  interpretation
                        of applicable law shall be deemed to have been a mistake
                        and  automatically  canceled,  and,  if received by  the
                        Bank, shall be refunded to the Borrower,  it  being  the
                        intention  of the Bank  and of the   Borrower  that such
                        interest  not be  payable   at a  rate in excess of such
                        maximum rate. Except as otherwise  provided  in  Section
                        2Cc or 2Cd of this Agreement, payments of such  interest
                        shall become due on the last day of each calendar month,
                        beginning on the first day of the first  calendar  month
                        after the calendar month in which Loan III or the  first
                        advance of any portion thereof is made.

                  f.    GENERAL PROVISIONS AS TO REPAYMENT AND PAYMENT.
                        Repayment of the principal amount of Loan  III,  payment
                        of all interest owing  pursuant  to  this  Agreement  in
                        connection  with  Loan  III  and  payment  of  all other
                        amounts owing by the  Borrower  to  the Bank pursuant to
                        this Agreement in connection with Loan III shall be made
                        in lawful money of the United States and in  immediately
                        available funds  at  the  banking  office  of  the  Bank
                        located at One Fountain Plaza, Buffalo, New York, or  at
                        such other office of the Bank as  may  at any  time  and
                        from time to time be specified in any  notice delivered,
                        given or sent to the  Borrower  by  the Bank.  No   such
                        repayment or   payment  shall be deemed  to  have   been
                        received by the Bank until received by the  Bank  at the
                        office of the Bank  determined in  accordance  with  the
                        preceding sentence, and any such  repayment  or  payment
                        received by the Bank at such  office  after 2:00 P.M. on
                        any day shall be deemed to have been  received  by   the
                        Bank at the time such office  opens  for business on the
                        next business day of the Bank.  If the time by which any
                        of the principal amount of Loan III is to be  repaid  is
                        extended by operation of law or otherwise,




                        the  Borrower  shall  pay  interest  on  the outstanding
                        portion  thereof  during  such  period  of  extension as
                        provided  in Section 2Ce of this Agreement.

                  g.    NON-USAGE FEE. For each period (i) beginning on the date
                        of this Agreement and ending on  the  last  day  of  the
                        calendar quarter containing such date or (ii) consisting
                        of  a  calendar  quarter beginning  after  the  calendar
                        quarter containing the date of this Agreement and ending
                        on or before June 30, 2000, the Borrower  shall  pay  to
                        the Bank on demand  made  by  the  Bank  a non-usage fee
                        equal to the product  obtained  by  multiplying  (A) the
                        difference  between  $3,000,000 and  the  daily  average
                        during such period of the outstanding  principal  amount
                        of Loan III first  by  (B)  1/4% and  then  by  (C)  the
                        fraction obtained by dividing the number of days in such
                        period by 360; provided,  however,  that (I) in no event
                        shall there be payable any such non-usage fee that would
                        result in  interest being  payable  on  the  outstanding
                        principal amount of Loan III at a rate in excess  of the
                        maximum rate permitted by applicable law and (II) solely
                        to the extent necessary to result  in  such interest not
                        being payable at a rate in excess of  such maximum rate,
                        any amount that  would be  treated  as  part   of   such
                        interest  under a   final  judicial   interpretation  of
                        applicable law shall be deemed to  have been  a  mistake
                        and automatically canceled and, if received by the Bank,
                        shall  be  refunded  to  the  Borrower,  it  being   the
                        intention of the Bank  and  of the  Borrower  that  such
                        interest not be  payable  at  a  rate in  excess of such
                        maximum rate.

read as follows:
