                 Money Indebtedness"), the Cash payments to be made into the
                 Deposit Account during an Insolvency Proceeding shall be
                 calculated pursuant to this Subsection (d). During any such
                 period, the Leverage Ratio and the Fixed Charge Coverage Ratio
                 shall be calculated (solely for purposes of Section 3 of this
                                      ------
                 Keep-Well Agreement) to ignore the effect of all outstanding
                 principal of, and payment of interest on, any Purchase Money
                 Indebtedness; provided that such principal and interest are
                               --------
                 concurrently taken into account to calculate amounts payable
                 under keep-well agreements substantially identical to this
                 Keep-Well Agreement in favor of the holders of Purchase Money
                 Indebtedness."

          2.     Section 8. Section 8 of the Keep-Well Agreement is amended by 
                 ---------
lower casing the initial word of the second sentence of Subsection (a) thereof

                 preceding sentence,"

       3.   Confirmation.  In all other respects, the Keep-Well Agreement is 
            ------------
hereby confirmed.
