                  equal to the amount of Acquisition Loans so prepaid or such
                  other amount as such Company deems appropriate in order to
                  make the Acquisition Loans of the Lenders ratable in

                  this subsection 7.1(c), (1) in no event shall any transaction
                  effected pursuant to this subsection 7.1(c) cause the

                  and (2) no Lender shall have any obligation to increase its
                  Acquisition Loan Commitment unless it agrees to do so in its
                  sole discretion. Each commitment increase supplement shall be
                  deemed to be a supplement to this Agreement.
