            WHEREAS, Company and Lenders desire to amend the Credit Agreement as
more particularly described below;

            NOW, THEREFORE, in consideration of the premises and the agreements,
provisions and covenants herein contained, the parties hereto agree as follows:

      SECTION 1. AMENDMENTS TO THE CREDIT AGREEMENT

1.1   AMENDMENTS TO SECTION 1: DEFINITIONS

            A. Subsection 1.1 of the Credit Agreement is hereby amended by
adding thereto the following definitions, which shall be inserted in proper
alphabetical order:

            "FIFTH AMENDMENT" means that certain Fifth Amendment to Credit

            "INCREASE EFFECTIVE DATE" has the meaning assigned to that term in
subsection 2.10C.

      B.    Subsection 1.1 of the Credit Agreement is hereby further amended by
deleting each of the definitions of "Commitments" and "Consolidated Excess Cash

from time to time in accordance with this Agreement.

<PAGE>

            "CONSOLIDATED EXCESS CASH FLOW" means, for any period, an amount (if
positive) equal to (i) Consolidated EBITDA for such period minus (ii) the sum,

period relating to the Merger or any Permitted Acquisition applied against
accruals and reserves taken against goodwill established in prior periods as

1.2   AMENDMENTS TO SECTION 2: AMOUNTS AND TERMS OF COMMITMENTS AND LOANS

      A.    Subsection of the Credit Agreement is hereby amended by
deleting subsections (ii) and (iii) thereof in their entirety and substituting
the following therefor:

            "(ii) Tranche B Term Loans. On the Closing Date, each Lender that
      had a Tranche B Term Loan Commitment as of such date loaned to Company an
      amount corresponding to such Lender's Pro Rata Share of the $350,000,000
      aggregate amount of the Tranche B Term Loan Commitments as of the Closing
      Date. On or after the Fifth Amendment Effective Date and prior to the
      Tranche B Term Loan Maturity Date, the aggregate amount of the Tranche B
      Term Loan Commitments may be increased from time to time in accordance
      with subsection 2.10. Following any such increase in the Tranche B Term
      Loan Commitments pursuant to subsection 2.10, each Lender that has
      increased its Tranche B Term Loan Commitment severally agrees to lend to
      Company in one or more borrowings an amount not exceeding the amount of
      such increase. Amounts borrowed under this subsection 2.1A(ii) and
      subsequently repaid or prepaid may not be reborrowed. The Tranche B Term
      Loan Commitments of Lenders shall be adjusted to give effect to any
      assignments of the Tranche B Term Loan Commitments pursuant to subsection
      10.1 B.

            (iii) Revolving Loans. Each Revolving Lender severally agrees,
      subject to the limitations set forth below with respect to the maximum
      amount of Revolving Loans permitted to be outstanding from time to time,
      to lend to Company from time to time during the period from the Closing
      Date to but excluding the Revolving Loan Commitment Termination Date an
      aggregate amount not exceeding its Pro Rata Share of the aggregate amount
      of the Revolving Loan Commitments to be used for the purposes identified
      in subsection 2.5C. The original amount of each Revolving Lender's

      annexed hereto and the aggregate original amount of the Revolving Loan
      Commitments is $200,000,000; provided that the Revolving Loan Commitments
      of Revolving Lenders shall be adjusted to give effect to (a) any increase

            and 2.7, each Term Loan and each Revolving Loan shall bear interest
            on the unpaid principal amount thereof from the date made through
            maturity (whether by acceleration or otherwise) at a rate determined
            by reference to the Base Rate or the Eurodollar Rate. Subject to the
            provisions of subsection 2.7, each Swing Line Loan shall bear
            interest on the unpaid principal amount thereof from the date

<PAGE>

            made through maturity (whether by acceleration or otherwise) at a
            rate determined by reference to the Base Rate. The applicable basis
            for determining the rate of interest with respect to any Term Loan
            or any Revolving Loan shall be selected by Company initially at the
            time a Notice of Borrowing is given with respect to such Loan
            pursuant to subsection 2.1B, and the basis for determining the
            interest rate with respect to any Term Loan or any Revolving Loan
            may be changed from time to time pursuant to subsection 2.2D. If on
            any day a Term Loan or Revolving Loan is outstanding with respect to
            which notice has not been delivered to Administrative Agent in
            accordance with the terms of this Agreement specifying the
            applicable basis for determining the rate of interest, then for that
            day that Loan shall bear interest determined by reference to the
            Base Rate.

                  (i)   Subject to the provisions of subsections 2.2E, 2.2G and
            2.7, the Revolving Loans, the Tranche A Term Loans and the Tranche B
            Term Loans shall bear interest through maturity as follows:

                  for which the applicable Pricing Certificate has been
                  delivered pursuant to subsection 6.1(iii); or

                  (b) if a Eurodollar Rate Loan, then at the sum of the
                  Eurodollar Rate plus the Eurodollar Rate Margin set forth in
                  the table below opposite the Consolidated Leverage Ratio for
                  the four-Fiscal Quarter period for which the applicable
                  Pricing Certificate has been delivered pursuant to subsection

            following the receipt by Administrative Agent of such Pricing
            Certificate (subject to the provisions of the foregoing clause (i));
            provided that, if at any time a Pricing Certificate is not delivered
            at the time required pursuant to subsection 6.1(iii), from the time
            such Pricing Certificate was required to be delivered until delivery
            of such Pricing Certificate, the applicable margins shall be the
            maximum percentage amount for the relevant Loan set forth above.

                  (iii) Subject to the provisions of subsections 2.2E, 2.2G and
            2.7, the Swing Line Loans shall bear interest through maturity at
            the sum of the Base Rate plus the applicable Base Rate Margin for
            Revolving Loans minus the Commitment Fee Percentage.

            Excess Cash Flow, minus (2) any Voluntary Prepayment Amount for such
            Fiscal Year minus (3) the aggregate amount for such Fiscal Year of

substance satisfactory to Administrative Agent and its counsel, provided that
Administrative Agent and, solely to the extent such Eligible Assignee is to have
a Revolving Loan Commitment, Swingline Lender and each Issuing Lender, shall
have consented to any such Eligible Assignee becoming a Lender. Company shall
have no right to increase Commitments pursuant to this subsection 2.10 except to
the extent Company obtains the agreement of one or more Lenders and/or Eligible
Assignees (and, in the case of any such Eligible Assignee, any requisite
consents) to accept such increase in Commitments.

      C.    EFFECTIVE DATE AND ALLOCATIONS. If the Commitments are increased in
accordance with this subsection 2.10, Administrative Agent and Company shall
determine the effective date (each, an "Increase Effective Date") and the final
allocation of such increase in Commitments. Administrative Agent shall promptly
notify Company and the Lenders (and any designated Eligible Assignees) of the
final allocation of such increase and the applicable Increase Effective Date.

      D.    CONDITIONS TO EFFECTIVENESS OF INCREASE. As a condition precedent to
each such increase in Commitments, Company shall deliver to Administrative Agent
an Officer's Certificate of Company dated as of the applicable Increase
Effective Date (i) certifying and attaching the resolutions adopted by Company
approving or consenting to such increase in Commitments, and (ii) certifying
that, before and after giving effect to such increase in Commitments:

            extent such representations and warranties specifically relate to an
            earlier date, in which case such representations and warranties are
            true, correct and complete in all material respects on and as of
            such earlier date; provided that where a representation and warranty
            is already qualified as to materiality, such representation and
            warranty shall be true, correct and complete as so qualified;

            (b)   no event has occurred and is continuing that would constitute
            an Event of Default or a Potential Event of Default; and

            (c)   each Loan Party has performed in all material respects all
            agreements and satisfied all conditions which this Agreement
            provides shall be performed or satisfied by it on or before the
            applicable Increase Effective Date.

Company shall either (1) prepay any Revolving Loans outstanding on the
applicable Increase Effective Date or (2) submit a Notice of Borrowing
requesting Revolving Loans as of the applicable Increase Effective Date (which
Revolving Loans shall be funded solely by the Revolving Lenders that have
increased their respective Revolving Loan Commitments as of such Increase
Effective Date), in each case solely to the extent necessary to keep the
outstanding Revolving Loans ratable with any revised Pro Rata Shares of
Revolving Loans arising from any nonratable increase in the Revolving Loan
Commitments under this subsection 2.10."
