         WHEREAS,  Borrower,  Agent  and the  Banks  are  parties  to a  certain
Last-In-First-Out  Credit  Agreement dated as of June 5, 2001, as amended and as
the  same  may from  time to time be  further  amended,  restated  or  otherwise

Agreement to modify certain provisions thereof; and

         WHEREAS,  each  capitalized  term  used  herein  shall  be  defined  in

         NOW,  THEREFORE,  in  consideration  of the  premises and of the mutual
covenants herein and for other valuable considerations,  Borrower, Agent and the

         suffer or permit at any time Consolidated Capital Expenditures, for the
         most recently  completed  fiscal year of the  Companies,  to be greater
         than (i) $23,216,000 for the fiscal year of the Companies  ending on or
         about August 31, 2002, and (ii)  $24,691,000 for the fiscal year of the
         Companies ending on or about August 31, 2003.

         4.       Addition  of New  Covenant.  Article  IV of the  Credit
Agreement  is hereby  amended to add the following new Section 4.23 thereto:

                  Section  4.23.  Strategic  Plan.  On and after  May 30,  2002,
         Borrower  will use  commercially  reasonable  efforts  to  execute  and
         perform in a timely manner Borrower's strategic plan which includes the
         disposal of certain  non-strategic assets as presented to Agent and the
         Banks (the "Strategic  Plan") and if Borrower shall fail at any time to
         be  proceeding  in a timely  and  commercially  reasonable  manner,  as
         determined by Agent in its sole  discretion,  then Borrower will pay to
         Agent,  for the pro rata  benefit of the  Creditors  (as defined in the
         Subordination Agreement), the fees agreed to between Borrower and Agent
         on the dates agreed to between Borrower and Agent.

         5.       Conditions   Precedent.   The  amendments  set  forth  above
shall  become  effective  upon  the satisfaction of the following conditions

instrument or document  binding upon or  enforceable  against  Borrower;  (d) no
Default or Event of Default  exists  under the  Credit  Agreement,  nor will any
