Subject to the terms and conditions hereof, each Revolving Credit Lender severally agrees to make revolving credit loans to the Borrower, from time to time during the Revolving Credit Commitment Period, in an aggregate principal amount at any one time outstanding which, when added to the aggregate principal amount of outstanding Swing Line Loans in which such Lender has purchased a participation (or, in the case of the Swing Line Lender, the Swing Line Loans made by such Swing Line Lender less the participations purchased in such Swing Line Loans by any other Lender) and such Lender's Commitment Percentage of the then outstanding L/C Obligations, does not exceed the amount of such Lender's Revolving Credit Commitment. During the Revolving Credit Commitment Period, the Borrower may use the Revolving Credit Commitments by borrowing, prepaying the Revolving Credit 5  Loans, in whole or in part, and reborrowing, all in accordance with the terms and conditions hereof. At any time not less than thirty (30) days prior to the Termination Date, the Borrower may increase the aggregate Commitments by (I) entering into a binding written agreement, substantially in the form of Exhibit G hereto, with any Lender to increase the Commitment of such Lender (an "Increased Commitment Agreement") which Increased Commitment Agreement shall be presented to the Agents for acknowledgment and acceptance (which shall not be withheld unless the effect thereof would be to exceed the maximum permitted amount herein for all Commitments, Facility B Commitments and Facility C Commitments (if Facility C exists) in the aggregate) and/or (II) subject to the First Offer Requirement (as defined below) enter into a binding written agreement substantially in the form of Exhibit H hereto (a "Lender Addition Agreement") with any bank, financial institution, or Investment Fund to become a Lender under this Agreement by making a Commitment and causing such Person to take all other actions required to become a new Lender hereunder (a "New Lender"); provided that the sum of (i) the aggregate Commitments of all Lenders (including New Lenders), (ii) the aggregate Facility B Commitments of all Facility B Lenders and (iii) the aggregate Facility C Commitments (if Facility C exists) of all Facility C Lenders (if Facility C exists) may not exceed, as of the date all or any portion of the Indebtedness comprising the Incremental Facility (as defined below) is incurred, an aggregate amount that would cause the Consolidated Senior Debt Ratio for the Borrower's most recently ended four full fiscal quarters for which internal financial statements are available to be greater than 2.0 to 1.0 (determined on a pro forma basis, assuming for purposes of this subsection 2.1(a) only, all of the proposed additional commitments had been incurred at the beginning of such four-quarter period and all Commitments of all Lenders, all Facility B Commitments of all Facility B Lenders and all Facility C Commitments (if Facility C exists) of all Facility C Lenders (if Facility C exists) that are outstanding immediately prior to giving effect to the incurrence of such proposed additional commitments have been drawn in full, but taking into account any payment or prepayment of any Term Loans or term loans under Facility C (if Facility C exists)) (such new or increased commitments, the "Incremental Facility"); and provided, further that, no consent of any Lender shall be required for such Incremental Facility except for the consents described under clauses (I) and (II) above. In order to become a New Lender, a party must execute a Lender Addition Agreement and deliver the same to the Administrative Agent, the Syndication Agent and the Borrower for counter-execution. On the Eurodollar Loans Maturity Date (or, subject to compliance with subsection 2.16, on any Business Day) occurring on or immediately following the date that (i) the Agents have acknowledged their acceptance of any Increased Commitment Agreement delivered pursuant to clause (I) above or (ii) any Lender Addition Agreement has been executed by all necessary parties and delivered to the Agents, the increase in any such Lender's Commitment contemplated thereby shall become effective and/or the New Lender shall become a party to this Agreement, as applicable. Promptly thereafter, the Administrative Agent shall amend Schedule I hereto to accurately reflect the Commitments of the Lenders then in existence, whereupon such amended Schedule I shall be substituted for the pre-existing Schedule I, be deemed a part of this Agreement without any further action or consent of any party and be promptly distributed to each Lender and the Borrower by the Administrative Agent. The 6  Incremental Facility shall have such economic terms (i.e., pricing, amount, tenor, amortization) as shall be agreed at the time with the lenders participating therein, and shall, otherwise, be on the same terms as this Agreement; provided that without the written consent of Required Class Lenders for each Class, (i) the applicable interest rate margin under the Incremental Facility shall not exceed the Applicable Margin under this Agreement or the "Applicable Margin" under and as defined in the Facility B Credit Agreement by more than fifty basis points and (ii) the maturity date of the Incremental Facility shall be equal to or occurring after the scheduled Termination Date under this Agreement or the "Termination Date" under and as defined in the Facility B Credit Agreement; provided, further, that if the Borrower chooses to implement the Incremental Facility pursuant to clause (I) or (II) above, the Incremental Facility shall have the same economic terms (i.e. pricing, tenor, amortization) as this Agreement. In the alternative, without the consent of any Lender, Borrower may cause the Incremental Facility to be implemented and separately documented as Facility C, which shall have BOA as the administrative agent and provide for a ratable sharing of all Collateral and Guarantee Obligations under the Guarantees among and between the Lenders, the Facility B Lenders and the Facility C Lenders. In any case, the Administrative Agent shall have the right to execute, on behalf of the Lenders, any amendments and/or other documents necessary to implement the Incremental Facility; provided that such amendments and/or other documents do not affect any of the rights or obligations of any Lender for which the written consent of such Lender is necessary under subsection 10.1 unless the written consent of such Lender is received by the Administrative Agent. When the Incremental Facility is not implemented and separately documented as Facility C, the Borrower shall send the Administrative Agent (for distribution to each Lender) a written offer to participate in the Incremental Facility pursuant to clause (I) above, and each such Lender shall have the right, but no obligation, to commit to a ratable portion of the Incremental Facility, provided that no later than fourteen (14) days after receipt of such written request, each such Lender shall advise the Administrative Agent and the Borrower whether it intends to participate in the Incremental Facility and the amount of its proposed commitment (the "First Offer Requirement"). Only after satisfying the First Offer Requirement and allocating requested commitments to Lenders requesting participation in such Incremental Facility shall Borrower be permitted to offer participation in any remaining commitments for the Incremental Facility to any proposed New Lender pursuant to clause (II) above." 1.5 Subsection 2.12(a) of the Credit Agreement is hereby amended and restated in its entirety to read as follows: "(a) Each borrowing by the Borrower from the Revolving Credit Lenders hereunder, each payment by the Borrower on account of any commitment fee hereunder and any reduction of the Revolving Credit Commitments of Revolving Credit Lenders shall be made pro rata according to the respective Commitment Percentages of the Revolving Credit Lenders. Except during any period in which an Event of Default has occurred and is continuing, each payment (including each prepayment) by the Borrower on account of principal of and interest on the Revolving Credit Loans, and any application by the Administrative Agent of the proceeds of any Collateral, shall be made pro rata according to the respective outstanding principal amounts of such Loans then 7  held by the Lenders.

At any time that an Event of Default has occurred and is continuing, all payments (including prepayments) made by the Borrower hereunder and any application by the Administrative Agent of the proceeds of any Collateral and/or payment under any Guarantee shall be applied in the following order: (1) to the ratable payment of all amounts due and owing by the Borrower pursuant to subsection 10.5 of this Agreement, subsection 10.5 of the Facility B Credit Agreement or subsection 10.5 of the Facility C Credit Agreement (if Facility C exists) to the Agents, the Facility B Agents and/or the Facility C Agents (if Facility C exists) and, after payment in full thereof, to any other Lender, Facility B Lender or Facility C Lender (if Facility C exists); (2) to the ratable payment of all interest, fees and commissions due and owing under this Agreement, the Facility B Credit Agreement or the Facility C Credit Agreement (if Facility C exists) or to the Agents, the Facility B Agents, the Facility C Agents (if Facility C exists), the Swing Line Lender, any Lender, any Facility B Lender or any Facility C Lender (if Facility C exists); and (3) to the ratable payment (or cash collateralization) of all other obligations of the Borrower to the Agents, the Facility B Agents, the Facility C Agents (if Facility C exists), the Swing Line Lender, any Lender, any Facility B Lender or any Facility C Lender (if Facility C exists) under any Credit Document, Facility B Credit Document, Facility C Credit Document (if Facility C exists) or Interest Rate Agreement with any Lender, any Facility B Lender or any Facility C Lender (if Facility C exists), including, without limitation the aggregate outstanding principal amount of Loans, Facility B Loans and Facility C Loans (if Facility C exists), the aggregate L/C Obligations, Facility B L/C Obligations and Facility C L/C Obligations (if Facility C exists) and the aggregate outstanding amount of Interest Rate Agreement Obligations to any Lender, any Facility B Lender and any Facility C Lender (if Facility C exists). For purposes of applying payments and proceeds distributed under clause 3 above, each Lender will first apply such amounts to all outstanding Loans and Interest Rate Agreement Obligations then due and owing to such Lender before such amounts will be held as cash collateral for L/C Obligations in which such Lender is a L/C Participant. The Administrative Agent, the Facility B Administrative Agent and the Facility C Administrative Agent (if Facility C exists) shall ratably distribute such payments to the applicable Lenders, the Facility B Lenders and the Facility C Lenders (if Facility C exists) promptly upon receipt in like funds as received. If any payment hereunder becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day, and, with respect to payments of 8  principal, interest thereon shall be payable at the then applicable rate during such extension." 1.6 Subsection 6.10(b) of the Credit Agreement is hereby amended and restated in its entirety to read as follows: "(b) With respect to any Person that, subsequent to the Original Closing Date, becomes a direct or indirect Subsidiary of the Borrower, promptly (and in any event within 30 days after such Person becomes a Subsidiary): (i) cause such new Subsidiary to become a party to the Subsidiary Guarantee and, to the extent such Subsidiary holds any Capital Stock of any Subsidiary that is not an Immaterial Subsidiary, to the Subsidiary Pledge Agreement and (ii) if requested by the Administrative Agent or the Required Lenders, deliver to the Administrative Agent legal opinions relating to the matters described in clause (i) immediately preceding, which opinions shall be in form and substance, and from counsel, reasonably satisfactory to the Administrative Agent.
