                                   FORM OF

                 The Company, certain lenders (the "Banks") and the Agent are
party to a Credit Agreement dated as of July 1, 1993 (as amended, supplemented

Banks party hereto are willing, to amend certain provisions of the Credit
Agreement, all on the terms and conditions of this Amendment.  Accordingly, in
consideration of the premises and the mutual agreements contained herein, and
for other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereto agree as follows:

                 Section 1.       Definitions.  Terms used but not defined
herein shall have the respective meanings ascribed to such terms in the Credit
Agreement.

                 Section 2.       Amendments.  Subject to the satisfaction of
the conditions to effectiveness specified in Section 4 hereof, but with effect
on and after the date hereof, the Credit Agreement shall be amended as follows:

                 A.       Certain Defined Terms.  Section 1.01 of the Credit
Agreement shall be amended:

                 (1)      by adding a sentence at the end of the definition of
         "Lien" therein reading as follows:

                          "For purposes of this Agreement, sales of accounts
                 receivable under any Permitted Receivables Facility shall not
                 be deemed to constitute Liens."; and

                 (2)      by adding the following new definition and inserting
         the same in the appropriate alphabetical location:

                          "Permitted Receivables Facility" shall mean a
                 receivables purchase facility entered into after December 5,
                 1994 pursuant to which the Company and/or one or more of its
                 Subsidiaries may at any time or from time to time sell, on
                 a non-recourse credit basis, accounts receivable arising in the
                 ordinary course of business.

                 B.       Sale of Assets.  Section 8.18 of the Credit Agreement

                 (2)      by replacing the period at the end of paragraph (e)
         thereof with "; and"; and

                 (3)      by adding a new paragraph (f) thereto reading as
         follows:

                          "(f)  so long as no Event of Default shall have
                 occurred and then be continuing, the Company and its
                 Subsidiaries may from time to time sell accounts receivable
                 arising in the ordinary course of business under Permitted
                 Receivables Facilities, provided that the aggregate face
                 amount of all such accounts receivable sold thereunder may not
                 exceed $300,000,000 at any one time outstanding."

                 C.       Delivery of Permitted Receivables Facilities

thereto reading as follows:

                 "8.20  Delivery of Permitted Receivables Facilities
         Agreements.  On or prior to the date of effectiveness of the first

         notify the Banks thereof promptly), and shall deliver to the Agent a
         certified or conformed copy of each of the principal agreements
         executed and delivered in connection therewith.  Promptly following
         each amendment, waiver and consent relating to a Permitted Receivables
         Facility, the Company shall give the Agent notice thereof (and the
         Agent shall notify the Banks thereof promptly), and shall deliver to
         the Agent a certified or conformed copy of each such amendment, waiver
         and consent."

                 Section 3.       Representations and Warranties.  The Company
represents and warrants to the Banks and the Agent that:

                 (a) this Amendment has been duly and validly executed and
         delivered by the Company and constitutes the Company's legal, valid
         and binding obligation, enforceable against the Company in accordance
         with its terms; and

                 (b) after giving effect to this Amendment, (i) no Default
         shall have occurred and be continuing and (ii) the representations and
         warranties made by the Company in Section 7 of the Credit Agreement

further amended, supplemented and otherwise modified and in effect from time to
time.

                 Section 6.       Counterparts.  This Amendment may be executed
in any number of counterparts, each of which shall be identical and all of
which, when taken together, shall constitute one and the same instrument, and
any of the parties hereto may execute this Amendment by signing any such
counterpart.

                 Section 7.       Binding Effect.  This Amendment shall be
binding upon and inure to the benefit of the parties hereto and their
