    (iii)(A)(3) of this Section 4(c);

        (d) as of the date hereof, no unwaived Default or Event of Default has
    occurred which is continuing; and

        (e) all the representations and warranties contained in Section 4 of
    the Credit Agreement are true and correct in all material respects with the
    same force and effect as if made by the Borrower on and as of the date 
    hereof.

        Section 5. Waiver. The Borrower has informed the Banks that the
Adjusted Leverage Ratio for the period ended November 1, 1997 was 2.1 to 1.0
which is in excess of the maximum level of 2.0 to 1.0 allowed under Section
6.18 of the Credit Agreement.  Upon satisfaction of the conditions set forth in
Section 6 of this Amendment, the Banks hereby waive Event of Default under the
Credit Agreement described in the immediately preceding sentence for the period
ended November 1, 1997.  This waiver is limited to the express terms hereof and
shall not extend to any other Default, Event of Default or any other period. 
This waiver shall not be and shall not be deemed to be a course of dealing upon
which the Borrower may rely with respect to any other Default, Event of Default
or request for a waiver and the Borrower hereby expressly waives any such
claim.
