                   statements and certificate were required to be delivered
                   (without giving effect to any applicable cure period) until
                   the date upon which they actually are delivered shall, except
                   as otherwise provided in clause (iii) below, be the
                   Applicable Margin as so increased;

                        (ii) if such financial statements and certificate are
                   delivered after the date such financial statements and

                   Days following the date upon which they actually are
                   delivered, the Applicable Margin (including in the case of
                   Alternate Base Rate Loans, Swing Line Loans) shall be
                   determined as if the relevant ratio of Consolidated Total
                   Debt to Consolidated EBITDA was 4.75x (it being understood
                   that the foregoing shall not limit the rights of the
                   Administrative Agent and the Lenders set forth in Section 9);
                   and

                  (b) the Applicable Margin for Tranche B Term Loans shall not
         be subject to adjustment based on the ratio of Consolidated Total Debt
         to Consolidated EBITDA.

entirety and substituting in lieu thereof the following definition:

                   Term Loans or Tranche B Term Loans shall extend beyond any
                   date which repayment of principal thereof is required to be
                   made pursuant to Section 2.7 or Section 2.7A, as applicable,
                   if, after giving effect to the selection of such Interest

                  2.8A Procedure for Tranche B Term Loan Borrowing. The Borrower
         shall give the Administrative Agent irrevocable notice (which notice
         must be received by the Administrative Agent prior to 12:00 Noon, New
         York City time, one Business Day prior to the Amendment Effective Date)
         requesting that the Tranche B Term Loan Lenders make the Tranche B Term
         Loans on the Amendment Effective Date and specifying the amount to be
         borrowed. Upon receipt of such notice the Administrative Agent shall
         promptly notify each Tranche B Term Lender thereof. On the Amendment
         Effective Date each Tranche B Term Loan Lender shall make available to
         the Administrative Agent at its office specified in Section 12.2 an
         amount in immediately available funds equal to the Tranche B Term Loan
         to be made by such Tranche B Term Loan Lender. The Administrative Agent
         shall on such date credit the account of the Borrower on the books of
         such office of the Administrative Agent with the aggregate of the
         amounts made available to the Administrative Agent by the Tranche B
         Term Loan Lenders.

     (d) by deleting clause (iii) of Section 2.8(b) and the word "and" preceding
such clause and substituting in lieu thereof the following:

         (iii) each Tranche A Term Loan Lender, such Tranche A Term Loan
         Lender's Tranche A Term Loan Commitment Percentage of the amounts
         specified in Section 2.7(b) (or, if less, the aggregate amount of the
         Tranche A Term Loans of such Tranche A Term Loan Lender then
         outstanding), on the dates specified in Section 2.7(b) (or such earlier
         date on which the Tranche A Term Loans become due and payable pursuant
         to Article 9); and (iv) each Tranche B Term Loan Lender, such Tranche B
         Term Loan Lender's Tranche B Term Loan Commitment Percentage of the
         amount specified in Section 2.7A(b) (or, if less, the aggregate amount
         of the Tranche B Term Loans of such Tranche B Term Loan 
   8
                                                                               8


         Lender than outstanding), on the date specified in Section 2.7A(b) (or
         such earlier date on which the Tranche B Term Loans become due and
         payable pursuant to Article 9).

         (e) by adding at the end of Section 2.9(a) the following:

         All prepayments of the Term Loans pursuant to this paragraph (a) shall
         be applied to the Tranche A Term Loans, on the one hand, and the
         Tranche B Term Loans, on the other, ratably based on the outstanding
         principal amounts thereof.

         (f) by deleting that portion of paragraph (b) of Section 2.9 which
appears before the proviso clause and substituting therefor the following:

                  (b) With respect to optional prepayments of the Term Loans,
         the first $10,000,000 of such optional prepayments of the Term Loans
         paid after the Amendment Effective Date shall be applied in such order
         as the Borrower may elect and, with respect to optional prepayments in
         excess of such $10,000,000, shall be applied to reduce the then
         remaining installments of the Tranche A Term Loans or Tranche B Term
         Loans, as the case may be, pro rata based upon the then remaining
         number of installments of such Term Loans, after giving effect to all
         prior reductions thereto (i.e., each then remaining installment of such
         Term Loans shall be reduced by an amount equal to the aggregate amount
         to be applied to such Term Loans divided by the number of the then
         remaining installments for such Term Loans); provided, however, that
         any prepayment of the Tranche A Term Loans with the proceeds of the
         Tranche B Term Loans shall not be deemed a prepayment solely for
         purposes of the first sentence of this Section 2.9(b);

         (g) by deleting therefrom Section 2.10(d) in its entirety and
substituting in lieu thereof the following:

                  (d) (i) All mandatory prepayments shall be applied first to
         the Tranche A Term Loans and the Tranche B Term Loans, pro rata based
         on the respective outstanding principal amounts thereof, and second to
         the permanent reduction of the Revolving Credit Commitments. The
         application of prepayments referred to in the preceding sentence shall
         be made first to Alternate Base Rate Loans and second to Eurodollar
         Loans. The amount of each principal prepayment of Term Loans shall be
         applied to reduce the then remaining installments of the Tranche A Term
         Loans and the Tranche B Term Loans, as the case may be, pro rata based
         upon the then remaining number of installments of Tranche A Term Loans
         and Tranche B Term Loans, respectively, after giving effect to all
         prior reductions thereto (i.e., each then remaining installment of such
         Term Loans shall be reduced by an amount equal to the aggregate amount
         to be applied to such Term Loans divided by the number of the then
         remaining installments for such Term Loans); provided, that if the
         amount to be applied to any installment as required by this Agreement
         would exceed the then remaining amount of such installment, then an
         amount equal to such excess shall be applied to the next succeeding
         installment after giving effect to all prior reductions thereof
         (including the amount of prepayments theretofore allocated pursuant to
         the preceding portion of this sentence). Amounts prepaid on account of
         the Term Loans may not be reborrowed.

                                                                               9


                  (ii) Any Lender holding Tranche B Term Loans may, to the
         extent Tranche A Term Loans are outstanding, elect on not less than one
         Business Day's prior written notice to the Administrative Agent with
         respect to any mandatory prepayment made pursuant to this Section 2.10,
         not to have such prepayment applied to such Lender's Tranche B Term
         Loans until all Tranche A Term Loans shall have been paid in full, in
         which case the amount not so applied shall be applied to prepay Tranche
         A Term Loans and shall reduce the then remaining installments of the
         Tranche A Term Loans ratably based on the number of such installments.

         (h) by adding immediately before the phrase "Term Loan Lender" in
Section 2.11(a) the word "applicable".

         3. Amendment to Section 4. Section 4.2(a) shall be amended by inserting
immediately before each occurrence of the phrase "Term Loan Lenders" the word
"applicable".

         4. Amendment to Section 5. Section 5 shall be amended as follows:

                  (a) Section 5.15 shall be amended by (a) adding the phrase
         "Tranche A" immediately before the phrase "Term Loans" and (b) adding
         the following sentence at the end thereof:

                           The proceeds of the Tranche B Term Loans shall be
                           used by the Borrower to make (i) an optional
                           $20,000,000 prepayment of the Tranche A Term Loans
                           and (ii) an optional $10,000,000 repayment of the
                           Revolving Credit Loans, each on the Amendment
                           Effective Date.

         (b)      The following new Section 5.27 shall be added:

                  5.27 Year 2000 Compliance. On or before September 30, 1999,
         the Borrower will complete any reprogramming and testing of major
         computer systems and other major equipment containing embedded
         microchips, in either case owned or operated by the Borrower or any of
         its Subsidiaries or used or relied upon in the conduct of their
         business, in order to enable their computer systems and equipment in
         the aggregate to be year 2000 compliant in all material respects. The
         costs to the borrower and its Subsidiaries that have not been incurred
         as of the date hereof for such reprogramming and testing and for the
         other reasonably foreseeable consequences to them of any improper
         functioning of other computer systems and equipment containing embedded
         microchips due to the occurrence of the year 2000 could not reasonably
         be expected to result in an Event of Default or to have a Material
         Adverse Effect.

         5. Amendment to Section 6. Section 6 shall be amended as follows:

                  outstanding under the Existing Credit Agreement shall have
