     THE PARTIES hereby agree as follows:

          "`Applicable Margin' means, at any date and with respect to each Loan,
     the applicable margin set forth below based upon the Debt/EBITDA Ratio as
     of such date (it being understood that measurement of the Debt/EBITDA as of
     any Measurement Date is sufficient for this purpose):

                                                      Applicable Margin
                                                 ----------------------------

     Notwithstanding the foregoing:

               (i) Prior to the date of final determination of EBITDA for the
          fiscal quarter of the Borrower to end on November 28, 1998, the

               (ii) If the Subordinated Debt Transaction shall not have been

          the Security Release Date."

          (b) Section 3.07(a) of the Credit Agreement shall be amended to read
     in its entirety as follows:

               "(a) The Commitment Fee. The Borrower agrees to pay to the
          Administrative Agent, for the respective accounts of the Lenders, on
          the last day of each calendar quarter of each year, commencing with
          the first such day after the Effective Date, and on the Commitment
          Termination Date, a fee (the "Commitment Fee") computed by applying
          (i) the applicable percentage per annum set forth below based on the
          Debt/EBITDA Ratio on each day during the then-ending quarter (or
          shorter period ending with the Commitment Termination Date) (it being
          understood that measurement of the Debt/EBITDA as of any Measurement
          Date is sufficient for this purpose) to (ii) the Available Commitment
          on such day:

                                                       Commitment Fee Percentage
              Debt/EBITDA Ratio                                Per Annum
              -----------------                        -------------------------
              4.00 or greater                                  0.350%
              3.50 or greater, but less than 4.00              0.300
              3.00 or greater, but less than 3.50              0.250
              2.50 or greater, but less than 3.00              0.225
              2.00 or greater, but less than 2.50              0.175
              Less than 2.00                                   0.125


          Prior to the date of final determination of EBITDA for the fiscal
          quarter of the Borrower to end on November 28, 1998, the Commitment
          Fee percentage per annum shall not be less than 0.250%."

          (c) Section 10.03(a) of the Credit Agreement shall be amended to read
     in its entirety as follows:

               "Section 10.03 Assignments. (a) Any Lender may at any time assign
          to one or more financial institutions (each an "Assignee") all, or a
          proportionate part of all, of its rights and obligations under this
          Agreement, and such Assignee shall assume such rights and obligations,
          pursuant to an instrument, in substantially the form of Exhibit F (an
          "Assignment and Acceptance"), executed by such Assignee and such
          transferor Lender, with (and subject to) the signed consent of the
          Borrower (which consent shall not be unreasonably withheld, provided
          that it shall not be unreasonable to withhold consent if such
          assignment would result in there being more than fifteen (15) Lenders
          (such number


                                      -2-

          to be increased to twenty (20) Lenders should the Subordinated Debt
          Transaction not be consummated within 135 days of the Effective Date))
          and the Administrative Agent (which consent shall not be unreasonably
          withheld); provided that (i) the foregoing consent requirement shall
          not be applicable in the case of an assignment or other transfer by
          any Lender to an Eligible Affiliate of such Lender, to another Lender
          or to a Federal Reserve Bank, (ii) the aforementioned consent of the
          Borrower shall not be required if there shall have occurred an Event
          of Default that is continuing and (iii) a Lender may only make an
          assignment or other transfer of its Loans or Commitment in the minimum
          amount of $5,000,000 or integral multiples of $1,000,000 in excess
          thereof unless such Lender's Loans or Commitment is less than
          $5,000,000, in which case such Lender may only make an assignment or
          other transfer of all of its Loans or Commitment. Upon execution and
          delivery of an Assignment and Acceptance and payment by such Assignee
          to such transferring Lender of an amount equal to the purchase price
          agreed between such transferring Lender and such Assignee and payment
          by the transferring Lender or the Assignee of an assignment fee of
          $3,500 to the Administrative Agent, such Assignee shall be a Lender
          party to this Agreement and shall have all the rights and obligations
          of a Lender with a Commitment as set forth in such Assignment and
          Acceptance, and the transferring Lender shall be released from its
          obligations hereunder to a corresponding extent, and no further
          consent or action by any party shall be required."

     Section 2. Miscellaneous.

          (a) All capitalized terms not otherwise defined in this Amendment
     shall have the meanings ascribed to them in the Credit Agreement.

          (b) All provisions in Article XI of the Credit Agreement shall apply
     to this Amendment with equal force and effect as if restated completely
     herein.

          (c) Except as set forth in Section 1 hereof, the Credit Agreement
     shall remain in full force and effect without amendment, modification or
     waiver. Execution and delivery hereof by a Lender shall not preclude the
     exercise by such Lender of any rights under the Credit Agreement (as
     amended by Section 1 hereof).

          (d) This Amendment shall be governed by and construed in accordance
     with the laws of the State of New York applicable to contracts made and to
     be performed entirely within such state.

          (e) This Amendment shall be effective on the first date as of which a
     counterpart hereof has been executed and delivered to the Administrative
     Agent under the Credit Agreement by the Borrower and the Required Lenders
     under the Credit Agreement.
