(e) Any increase in the aggregate Revolving Commitments or the addition of the Term Loan B hereunder shall be subject to the following conditions: (A) unless otherwise agreed by the Borrower and the Administrative Agent, the Commitment of any New Lender shall not be less than $10,000,000; (B) unless otherwise agreed by the Borrower and the Administrative Agent, the increase in the Commitment of any Lender shall be not less than $5,000,000; (C) after giving effect to all Revolving Loan Increase Requests and the Term Loan B Request, if applicable, (i) the aggregate Commitments shall not exceed $450,000,000 and (ii) the sum of the aggregate of all Revolving Loan Increase Requests and the Term Loan B Request, if applicable, delivered hereunder shall not exceed $100,000,000; (D) the Borrower and each Additional Lender shall have executed and delivered a Commitment and Acceptance and the Administrative Agent shall have accepted and executed the same (which acceptance shall not be unreasonably withheld); (E) the Borrower shall have executed and delivered to the Administrative Agent a Note or Notes payable to the order of each Additional Lender, each such Note to be in the amount of such Additional Lender’s Revolving Commitment, increased Revolving Commitment, or Term Loan B Commitment (as applicable); (F) the Borrower shall have delivered to the Administrative Agent an opinion of counsel (similar to the form of opinion delivered on the Closing Date, modified to apply to the increase in the aggregate Revolving Commitments or the Term Loan B and each Note and Commitment and Acceptance executed and delivered in connection therewith) and resolutions of its board of directors approving such increase in the aggregate Revolving Commitments or the Term Loan B; (G) the Guarantors shall have delivered to the Administrative Agent a written instrument confirming their consent to the new Revolving Commitments, increased Revolving Commitments, or Term Loan B Commitments (as applicable) and that the Guaranty continues in full force and effect and resolutions of the board of directors of each of the Guarantors approving the guaranty of such increase in the aggregate Revolving Commitments or the Term Loan B; (H) the Borrower and each Additional Lender shall otherwise have executed and delivered such other instruments and documents as the Administrative Agent shall have reasonably requested in connection with such new Revolving Commitment, increased Revolving Commitment, or Term Loan B Commitment (as applicable); (I) the Borrower shall have completed and delivered to the Administrative Agent Schedule 2.08 in

(f) On the effective date of any increase in the aggregate Revolving Commitments pursuant to the provisions hereof (“Increase Date”), which Increase Date shall be mutually agreed upon by the Borrower, each applicable Additional Revolving Lender and the Administrative Agent, each Additional Revolving Lender shall make a payment to the Administrative Agent in an amount sufficient, upon the application of such payments by all Additional Revolving Lenders to the reduction of the outstanding Revolving Loans held by Revolving Lenders, to cause the principal amount outstanding under such Revolving Loans made by all Revolving Lenders (including any Additional Revolving Lender) to be in the proportion of their respective Revolving Commitments (as of such Increase Date). The Borrower hereby irrevocably authorizes each Additional Revolving Lender to fund to the Administrative Agent the payment required to be made pursuant to the immediately preceding sentence for application to the reduction of the outstanding Revolving Loans held by each Revolving Lender, and each such payment shall constitute a Revolving Loan hereunder. Each Additional Revolving Lender shall also advance ratably in proportion of its respective Revolving Commitment its share of all Revolving Loans made on or after such Increase Date and shall otherwise have all of the rights and obligations of a Revolving Lender hereunder on and after such Increase Date. Notwithstanding the foregoing, upon the occurrence of an Event of Default prior to the date on which an Additional Revolving Lender is holding Revolving Loans equal to its proportionate share of all Revolving Loans hereunder, such Additional Revolving Lender shall, upon notice from Administrative Agent, on or after the date on which the Obligations are accelerated or become due following such Event of Default, pay to Administrative Agent (for the account of the other Revolving Lenders, to which the Administrative Agent shall pay their pro rata shares upon receipt) a sum equal

to such Additional Revolving Lender’s proportionate share of each Revolving Loan then outstanding with respect to which such Additional Revolving Lender does not then hold its proportionate share thereof.

(g) On the Increase Date and the making of the Revolving Loans by an Additional Revolving Lender in accordance with the provisions of the first sentence of this Section 2.08, such Additional Lender shall also be deemed to have irrevocably and unconditionally purchased and received, without recourse or warranty, from Lenders party to this Agreement immediately prior to the Increase Date, an undivided interest and participation in any Letters of Credit then outstanding, ratably, such that all Revolving Lenders (including each Additional Lender) hold participation interests in each such Letters of Credit in the proportion of their respective Revolving Commitments (taking into account the increase in the aggregate Revolving Commitments that is effective on such Increase Date).

(h) Each Additional Term Loan B Lender severally agrees, on the terms and conditions set forth herein, to make a term loan to the Borrower on the effective date of the Term Loan B which date shall be mutually agreed upon by the Borrower and the Administrative Agent (the “Term Loan B Advance Date”). The Term Loan B shall be made by the several Term Loan B Lenders ratably in proportion to their respective Term Loan B Commitments on the Term Loan B Advance Date.

(i) Nothing contained herein shall constitute, or otherwise be deemed to be, a commitment or agreement on the part of any Lender to increase its Commitment hereunder at any time or a commitment or agreement on the part of the Borrower or the Administrative Agent to give or grant any Lender the right to increase its Commitment hereunder at any time.

amount of the outstanding Revolving Loans, if any (together with interest accrued thereon and any amount due under Section 10.05(a)), as may be necessary so that after such payment the aggregate unpaid principal amount of the Revolving Loans does not exceed the aggregate amount of the Revolving Commitments as then reduced. If the principal amount of all Revolving Loans have been repaid yet the outstanding Letter of Credit Obligations then exceed the Revolving Commitment, the Borrower shall deposit cash collateral with the Administrative Agent with respect to such outstanding Letter of Credit Obligations in an amount necessary so that the outstanding Letter of Credit Obligations do not exceed the Revolving Commitments. Each such payment or prepayment shall be applied ratably to the Revolving Loans of the Revolving Lenders outstanding on the date of payment or prepayment in the following order of priority: (i) first, to Base Rate Loans; and (ii) secondly, to Eurodollar Loans.

The Borrower further authorizes the Administrative Agent to credit the proceeds of such Revolving Loan so as to immediately eliminate the liability of the Borrower for Reimbursement Obligations under such Letter of Credit.

(b) Duties of the Issuing Bank. Any action taken or omitted to be taken by the Issuing Bank in connection with any Letter of Credit, if taken or omitted in the absence of willful misconduct or gross negligence, shall not put the Issuing Bank under any resulting liability to any Lender, or, assuming that the Issuing Bank has complied with the procedures specified in Section 3.04 and such

Lender has not given a notice contemplated by Section 3.06(a) that continues in full force and effect, relieve that Lender of its obligations hereunder to the Issuing Bank. In determining whether to pay under any Letter of Credit, the Issuing Bank shall have no obligation relative to the Lenders other than to confirm that any documents required to have been delivered under such Letter of Credit appear to comply on their face, with the requirements of such Letter of Credit.

(b) Sharing of Letter of Credit Payments. In the event that the Issuing Bank makes any payment under any Letter of Credit for which the Borrower shall not have repaid such amount to the Issuing Bank pursuant to Section 3.07 or which cannot be paid by a Revolving Loan pursuant to clause (a)(iii) of Section 3.05, the Issuing Bank shall promptly notify each Revolving Lender of such failure, and each Revolving Lender shall promptly and unconditionally pay to the Issuing Bank such Revolving Lender’s ratable share of the amount of such payment in Dollars and in same day funds.

The failure of any Revolving Lender to make available to the Issuing Bank its ratable share of any such payment shall neither relieve nor increase the obligation of any other Revolving Lender hereunder to make available to the Issuing Bank its ratable share of any payment on the date such payment is to be made.

(c) Sharing of Reimbursement Obligation Payments. Whenever the Issuing Bank receives a payment on account of a Reimbursement Obligation, including any interest thereon, as to which the Issuing Bank has received any payments from the Revolving Lenders pursuant to this Section 3.06, it shall promptly pay to each Revolving Lender which has funded its participating interest therein, in Dollars and in the kind of funds so received, an amount equal to such Revolving Lender’s ratable share thereof. Each such payment shall be made by the Issuing Bank on the Business Day on which the funds are paid to such Person, if received prior to 10:00 a.m. (Eastern time) on such Business Day, and otherwise on the next succeeding Business Day.

If any Lender notifies the Borrower in writing of suspension of its obligations to make, maintain or fund its Eurodollar Loans under Section 10.02, if any Lender requests compensation under Section 10.05, if any Loan Party is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 10.06, if any Lender is a Defaulting Lender, or any Lender fails to either (i) maintain an investment grade rating from Standard and Poor’s or Moodys or (ii) maintain assets of at least $500,000,000, then the Borrower may, at its sole expense and effort, upon written notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required

by, Section 12.07), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations (which Eligible Assignee may be another Lender, if a Lender accepts such assignment), provided that: (A) the Borrower shall have paid to the Administrative Agent the processing and recordation fee specified in Section 12.07; (B) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in Letter of Credit Obligations, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 10.04) from the Eligible Assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts); (C) in the case of any such assignment resulting from a claim for compensation under Section 10.05 or payments required to be made pursuant to Section 10.06, such assignment will result in a reduction in such compensation or payments thereafter; and (D) such assignment does not conflict with applicable law.
