                              W I T N E S S E T H:

            WHEREAS, the Company, the Lenders and the Administrative Agent are
parties to the Credit Agreement;

            WHEREAS, the Company has requested that the Administrative Agent,

            WHEREAS, the Administrative Agent, with the consent of the Required
Lenders, is agreeable to the requested amendments, but only on the terms and
subject to the conditions set forth herein;

            NOW THEREFORE, in consideration of the premises herein contained and
for other good and valuable consideration, the receipt of which is hereby
acknowledged, the parties hereto hereby agree as follows:

            1. Defined Terms. Unless otherwise defined herein, capitalized terms

            2. Amendments to Subsection 8.11. (a) Subsection 8.11(e) of the
Credit Agreement is hereby amended by deleting the word "and" at the end of such
subsection.

            (b) Subsection 8.11(f) of the Credit Agreement is hereby amended by
deleting the existing subsection 8.11(f) in its entirety and by substituting in
lieu thereof the following new subsection 8.11(f):

                  "(f) so long as no Default or Event of Default has occurred or
            would occur after giving effect to such declaration or payment, the
            Company may, at any time that (i) the Leverage Ratio in effect is
            equal to or less than 1.5:1.0 or (ii) the aggregate principal amount
            of Term Loans then outstanding is less than $200,000,000, declare
            and pay cash


                                                                               2


            dividends to Holdings on the common stock of the Company, provided
            that the aggregate amount thereof paid in any fiscal year of the
            Company, together with any Stock Repurchase Dividends (as defined
            below) made under paragraph (g) of this subsection 8.11 during such
            fiscal year, does not exceed an amount equal to 25% of Consolidated
            Net Income for such fiscal year; and"

            (c) Subsection 8.11 of the Credit Agreement is hereby amended by
adding the following new paragraph (g) to the end of such subsection:

                  "(g) so long as no Default or Event of Default has occurred or
            would occur after giving effect to such declaration or payment, the
            Company may, at any time and from time to time, declare and pay cash
            dividends to Holdings on the common stock of the Company, in an
            aggregate amount of up to $200,000,000, in order to enable Holdings
            to repurchase shares of its own common stock for an aggregate
            purchase price of $200,000,000 pursuant to a share repurchase
            program (such cash dividends, the "Stock Repurchase Dividends"),
            provided that the Company does not use more than $100,000,000 in
            proceeds from Revolving Credit Loans to finance such Stock
            Repurchase Dividends (it being understood that this proviso shall in
            no way limit the Company from using proceeds from Revolving Credit
            Loans for any other purpose)."

            3. Effectiveness. This Amendment shall become effective as of the
date the Administrative Agent shall have received counterparts hereof duly
executed by the Company, the Administrative Agent and the Required Lenders.

            4. Representations and Warranties. The Company hereby represents and
warrants that each of the representations and warranties in or pursuant to
Section 5 of the Credit Agreement or which are contained in any other Credit
Document or in any certificate, document or financial or other statement
furnished by or on behalf of Holdings, the Company or any Subsidiary thereof
shall be, after giving effect to this Amendment, true and correct in all
material respects as if made on and as of the date hereof (unless such
representations and warranties are stated to relate to a specific earlier date,
in which case such representations and warranties shall be true and correct in
all material respects as of such earlier date).

            5. Continuing Effect of Credit Agreement. This Amendment shall not
be construed as a waiver or consent to any further or future action on the part
of the Company that would require a waiver or consent of the Administrative
Agent and/or the Lenders. Except as amended hereby, the provisions of the Credit
Agreement are and shall remain in full force and effect.

            6. Counterparts. This Amendment may be executed in counterparts and
all of the said counterparts taken together shall be deemed to constitute one
and the same instrument.


                                                                               3


            7. GOVERNING LAW. THIS AMENDMENT SHALL BE GOVERNED BY, AND CONSTRUED
AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

            8. Expenses. The Company agrees to pay or reimburse the
Administrative Agent for all of its out-of-pocket costs and expenses incurred in
connection with the preparation, negotiation and execution of this Amendment,
including, without limitation, the fees and disbursements of counsel to the
Administrative Agent.


                                                                               4


            IN WITNESS WHEREOF, the parties hereto have caused this Amendment to
be executed and delivered by their duly authorized officers as of the date first
written above.
