33 Revolving Letter of Credit that is automatically renewable annually shall, (x) permit such beneficiary, upon receipt of such Notice of Non-Renewal, to draw under such Revolving Letter of Credit prior to the date such Revolving Letter of Credit otherwise would have expired and (y) not permit the expiration date (after any renewal) of such Revolving Letter of Credit in any event to be extended to a date later than 10 Business Days before the Revolving Credit Termination Date. If a “Notice of Non-Renewal” is given by any Revolving Issuing Bank pursuant to the immediately preceding sentence, such Revolving Letter of Credit shall expire on the expiry date. Within the limits of the Revolving Letter of Credit Facility and subject to the limits referred to above, the Borrower may request the issuance of Revolving Letters of Credit under this Section 2.01, repay any Unreimbursed Amounts resulting from drawings thereunder pursuant to Section 2.03(d)(i) or repay any Revolving Letter of Credit Loan resulting from drawings thereunder pursuant to Section 2.03(d)(ii), and request the issuance of additional Letters of Credit under this Section 2.01. SECTION 2.02. Making the Loans. (a) Each Revolving Credit Borrowing shall be made following the issuance of a Notice of Borrowing, given not later than 11:00 A.M. (New York City time) (x) subject to the following clause (y), on the third Business Day prior to the date of the proposed Revolving Credit Borrowing, in the case of a Borrowing in a principal amount of up to $25,000,000, or (y) the tenth Business Day prior to the date of the proposed Revolving Credit Borrowing, in the case of any Borrowing that, together with all other Borrowings requested within the preceding 10 consecutive Business Days, would result in the aggregate principal amount of such Borrowings being greater than $25,000,000 (except in the case of the initial Borrowing on the Effective Date), by the Borrower to the Administrative Agent, which shall give to each Appropriate Lender prompt notice thereof by telecopier or electronic communication. Each such Notice of Borrowing shall be by telephone, confirmed immediately in writing, or by telecopier or electronic communication, in substantially the form of Exhibit B-1 hereto, specifying therein the requested (i) date of such Revolving Credit Borrowing, and (ii) aggregate amount of such Borrowing. Each Appropriate Lender shall, before 11:00 A.M. (New York City time) on the date of such Revolving Credit Borrowing, make available for the account of its Lending Office to the Administrative Agent at the Administrative Agent’s Account, in same day funds, such Lender’s ratable portion of such Revolving Credit Borrowing in accordance with the respective Commitments under the Revolving Credit Facility of such Lender and the other Appropriate Lenders. After the Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Administrative Agent will make such funds available to the Borrower by crediting the Operating Account. (b) The Term B Borrowing consisting of Term B Loans advanced by the Term B Lenders on the Effective Date shall be made following the issuance of a Notice of Borrowing, given not later than 11:00 A.M. (New York City time) on the third Business Day prior to the date of the proposed Term B Borrowing, by the Borrower to the Administrative Agent, which shall give to the Term B Lenders prompt notice thereof by telecopier or electronic communication. Each such Notice of Borrowing shall be by telephone, confirmed immediately in writing, or by telecopier or electronic communication, in substantially the form of Exhibit B-1 hereto, specifying therein the requested (i) date of such Term B Borrowing (which shall be the Effective Date), and (ii) aggregate amount of such Term B Borrowing. Each Term B Lender

34 shall, before 11:00 A.M. (New York City time) on the date of such Term B Borrowing, make available for the account of its Lending Office to the Administrative Agent at the Administrative Agent’s Account, in same day funds, its Pro Rata Share of the amount of such Term B Borrowing in accordance with its Commitment under the Term B Facility. After the Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Borrower hereby directs the Administrative Agent to apply such funds to the repayment of the Existing Debt of MACH Gen and the Guarantors. (c) Notwithstanding anything to the contrary in this Article II, in connection with Loans requested to be made on the Effective Date, if the proceeds of such Loans will be used exclusively to repay and/or refinance in full all obligations of the Existing Loan Parties outstanding on the Effective Date under the Pre-Petition First Lien Credit Agreement and the DIP Credit Agreement, the request for the Borrowing of such Loans may be given by the Borrower to the Administrative Agent telephonically or by electronic communication, not later than 11:00 A.M. (New York City time) on the third Business Day prior to the proposed Effective Date, if such request is confirmed in writing by a Notice of Borrowing given not later than 11:00 A.M. (New York City time) on the proposed Effective Date. (d) [Reserved]. (e) Each Notice of Borrowing shall be irrevocable and binding on the Borrower. The Borrower shall indemnify each Appropriate Lender against any loss, cost or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the applicable conditions set forth in Article III, including, without limitation, any loss (excluding loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Loan to be made by such Lender as part of such Borrowing when such Loan, as a result of such failure, is not made on such date. (f) Unless the Administrative Agent shall have received notice from an Appropriate Lender prior to the date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s ratable portion of such Borrowing, the Administrative Agent may assume that such Lender has made such portion available to the Administrative Agent on the date of such Borrowing in accordance with subsection (a) of this Section 2.02 and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made such ratable portion available to the Administrative Agent, such Lender and the Borrower severally agree to repay or pay to the Administrative Agent forthwith on demand such corresponding amount and to pay interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid or paid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable at such time under Section 2.07 to Loans comprising such Borrowing and (ii) in the case of such Lender, the Eurodollar Rate. If such Lender shall pay to the Administrative Agent such corresponding amount, such amount so paid shall constitute such Lender’s Loan as part of such Borrowing for all purposes.

35 (g) The failure of any Lender to make the Loan to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its Loan on the date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Loan to be made by such other Lender on the date of any Borrowing. SECTION 2.03. Issuance of and Drawings and Reimbursements Under Revolving Letters of Credit. (a) Request for Issuance. Each Revolving Letter of Credit shall be issued upon notice, given not later than 11:00 A.M. (New York City time) (x) subject to the following clause (y), on the third Business Day prior to the date of the proposed issuance of such Revolving Letter of Credit, in the case of a Revolving Letter of Credit with an Available Amount of up to $25,000,000, or (y) the tenth Business Day prior to the date of the proposed issuance of such Revolving Letter of Credit, in the case of a Revolving Letter of Credit with an Available Amount that, together with the Available Amount of all other Revolving Letters of Credit requested within the preceding 10 consecutive Business Days, would result in the aggregate Available Amount of all such Revolving Letters of Credit being greater than $25,000,000 (except in the case of the initial Revolving Letters of Credit to be issued or deemed issued on the Effective Date), by the Borrower to the Administrative Agent, which shall give to the Revolving Issuing Bank prompt notice thereof by telecopier or electronic communication by no later than 5:00 P.M. (New York time) at least three Business Days or ten Business Days, as the case may be, prior to the date of the proposed issuance. The notice of issuance of any Revolving Letter of Credit shall be substantially in the form attached hereto as Exhibit B-2 (a “Notice of Issuance”) and shall be in writing or by telecopier or electronic communication (and confirmed by telephone), specifying therein the requested (i) date of such issuance (which shall be a Business Day), (ii) Available Amount of such Revolving Letter of Credit, (iii) expiration date of such Revolving Letter of Credit, (iv) name and address of the beneficiary of such Revolving Letter of Credit, (v) supportable obligation and (vi) form of such Revolving Letter of Credit. If the requested form of such Revolving Letter of Credit is acceptable to the Revolving Issuing Bank in its sole discretion, the Revolving Issuing Bank will, upon fulfillment of the applicable conditions set forth in Article III, make such Revolving Letter of Credit available to the Borrower at its office referred to in Section 9.02 or as otherwise agreed with the Borrower in connection with such issuance. Notwithstanding anything herein to the contrary, no Revolving Issuing Bank shall be under any obligation to issue any Revolving Letter of Credit if (x) any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain such Revolving Issuing Bank from issuing such Revolving Letter of Credit, or any law applicable to such Revolving Issuing Bank or any directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over such Revolving Issuing Bank shall prohibit, or direct that such Revolving Issuing Bank refrain from, the issuance of letters of credit generally or such Revolving Letter of Credit in particular or shall impose upon such Revolving Issuing Bank with respect to such Revolving Letter of Credit any restriction, reserve or capital requirement (for which such Revolving Issuing Bank is not otherwise compensated hereunder), or shall impose upon such Revolving Issuing Bank any unreimbursed loss, cost or expense (for which such Revolving Issuing Bank is not otherwise compensated hereunder) or (y) any Lender under the Revolving Letter of Credit Facility is a Defaulting Lender, unless such Revolving Issuing Bank has entered into arrangements with the

36 Borrower or such Defaulting Lender satisfactory to such Revolving Issuing Bank to eliminate such Revolving Issuing Bank's risk with respect to such Defaulting Lender. (b) Revolving Letter of Credit Reports. Each Revolving Issuing Bank shall promptly (i) notify the Administrative Agent in writing of the amount and expiry date of each Revolving Letter of Credit issued by it and (ii) provide a copy of such Revolving Letter of Credit (and any amendments, renewals or extension thereof) to the Administrative Agent. (c) Participations in Revolving Letters of Credit. Upon the issuance of each Revolving Letter of Credit and, in the case of the Existing Letters of Credit, upon the Effective Date, without further action, each Revolving Credit Lender shall be deemed to have irrevocably purchased, to the extent of its Pro Rata Share, a participation interest in such Revolving Letter of Credit and such Revolving Credit Lender shall, to the extent of its contingent obligation or Pro Rata Share, be responsible for reimbursing the Revolving Issuing Bank in respect of any Unreimbursed Amount in accordance with Section 2.03(d) (with the terms of this Section surviving the termination of this Agreement). (d) Drawing and Reimbursement; Funding of Participations. (i) Upon receipt from the beneficiary of any Revolving Letter of Credit of any notice of drawing under such Revolving Letter of Credit, the Revolving Issuing Bank that issued such Revolving Letter of Credit shall notify promptly the Borrower and the Administrative Agent thereof. On the same Business Day on which any payment is made by any Revolving Issuing Bank under a Revolving Letter of Credit (each such date, an “Honor Date”), the Borrower shall reimburse such Revolving Issuing Bank through the Administrative Agent in an amount equal to the amount of such drawing. If the Borrower fails to so reimburse any Revolving Issuing Bank by such time (it being acknowledged and agreed that any such failure shall not be a Default hereunder), the Administrative Agent shall promptly notify each Appropriate Lender of the Honor Date, the amount of the unreimbursed drawing (the “Unreimbursed Amount”), and the amount of such Appropriate Lender’s Pro Rata Share thereof. In such event, in the case of an Unreimbursed Amount under a Revolving Letter of Credit, the Borrower shall be deemed to have requested a Revolving Credit Borrowing of Loans under the Revolving Credit Facility, to be disbursed on the Business Day immediately following the Honor Date in an amount not to exceed the Unreimbursed Amount thereof subject to the amount of the Unused Revolving Credit Commitments (without regard, in each case, to the conditions set forth in Section 3.02). Any notice given by a Revolving Issuing Bank or the Administrative Agent pursuant to this Section 2.03(d) may be given by telephone if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice. Unreimbursed Amounts shall bear interest at the Eurodollar Rate plus the Applicable Margin, from the Honor Date until such Unreimbursed Amount shall be repaid or converted into a Revolving Letter of Credit Loan, payable on demand. (ii) Each Revolving Credit Lender shall upon any notice pursuant to Section 2.03(d)(i) make funds available for the account of its Lending Office to the Administrative Agent for the account of the Revolving Issuing Bank by deposit to the

37 Administrative Agent’s Account, in same day funds, an amount equal to such Lender’s Pro Rata Share of any Unreimbursed Amount in respect of any Revolving Letter of Credit issued by such Revolving Issuing Bank not later than 11:00 A.M. (New York City time) on the Business Day specified in such notice by the Administrative Agent, whereupon, subject to the provisions of subsection (iii), each Revolving Credit Lender that so makes funds available to the Revolving Issuing Bank shall be deemed to have made a Eurodollar Rate Loan to the Borrower in such amount. The Administrative Agent shall remit the funds so received to the Revolving Issuing Bank. (iii) Until each Revolving Credit Lender funds its Revolving Credit Loan or Revolving Letter of Credit Loan pursuant to this Section 2.03(d) to reimburse the Revolving Issuing Bank for any amount drawn under any Revolving Letter of Credit issued by the Revolving Issuing Bank, interest in respect of such Lender’s Pro Rata Share of such amount shall be solely for the account of the applicable Revolving Issuing Bank. (iv) Each Revolving Credit Lender’s obligation to make Revolving Credit Loans or Revolving Letter of Credit Loans to reimburse the Revolving Issuing Bank for amounts drawn under any Revolving Letter of Credit issued by the Revolving Issuing Bank, as contemplated by this Section 2.03(d), shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Revolving Credit Lender may have against the Revolving Issuing Bank, the Borrower or any other Person for any reason whatsoever; (B) the occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing. (v) If any Revolving Credit Lender fails to make available to the Administrative Agent for the account of the Revolving Issuing Bank any amount required to be paid by such Revolving Credit Lender pursuant to the foregoing provisions of this Section 2.03(d) by the time specified in Section 2.03(d)(ii), the Revolving Issuing Bank shall be entitled to recover from such Revolving Credit Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the Revolving Issuing Bank at a rate per annum equal to the Eurodollar Rate plus the Applicable Margin from time to time in effect. A certificate of the Revolving Issuing Bank submitted to any Revolving Credit Lender (through the Administrative Agent) with respect to any amounts owing under this Section 2.03(d)(v) shall be conclusive absent manifest error. (vi) If, at any time after the Revolving Issuing Bank has made a payment under any Revolving Letter of Credit and has received from any Revolving Credit Lender such Lender’s Revolving Letter of Credit Loan in respect of such payment in accordance with this Section 2.03(d), the Administrative Agent receives for the account of such Revolving Issuing Bank any payment in respect of the related Unreimbursed Amount or interest thereon (whether directly from the Borrower, or otherwise, including proceeds of Collateral applied thereto by the Administrative Agent), the Administrative Agent will distribute to such Revolving Credit Lender its Pro Rata Share thereof (appropriately adjusted, in the case of interest payments, to reflect the period of time

38 during which such Revolving Credit Lender’s Revolving Letter of Credit Loan was outstanding) in the same funds as those received by the Administrative Agent. (vii) If any payment received by the Administrative Agent for the account of any Revolving Issuing Bank pursuant to Section 2.03(d)(i) is required to be returned under any of the circumstances described in Section 9.11 (including pursuant to any settlement entered into by the Revolving Issuing Bank in its discretion), in the case of a Revolving Letter of Credit, each Revolving Credit Lender shall pay for the account of its Lending Office to the Administrative Agent for the account of such Revolving Issuing Bank its Pro Rata Share thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned by such Revolving Credit Lender, at a rate per annum equal to the Eurodollar Rate from time to time in effect. (e) Existing Letters of Credit Refinanced. As of the date hereof, the Borrower acknowledges that certain letters of credit as set forth in Schedule 2.03(e) (the “Existing Letters of Credit”) have been issued by or on behalf of the Initial Revolving Issuing Bank for the account of MACH Gen and the Guarantors (the “Existing Loan Parties”). The parties agree that all reimbursement and other obligations of the Existing Loan Parties in respect of the Existing Letters of Credit, if then outstanding, shall be refinanced by the Revolving Letter of Credit Facility under this Agreement with effect from the Effective Date and thereafter such letters of credit will be deemed for all purposes of the Loan Documents to have been provided for the account of the Borrower and the Guarantors under the Revolving Letter of Credit Facility under this Agreement. (f) [Reserved]. (g) Obligations Absolute. The Obligations of the Borrower under this Agreement and any other agreement or instrument relating to any Revolving Letter of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement and such other agreement or instrument under all circumstances, including, without limitation, the following circumstances: (i) any lack of validity or enforceability of any Loan Document, any Revolving Letter of Credit or any other agreement or instrument relating thereto (all of the foregoing being, collectively, the “L/C Related Documents”); (ii) any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations of the Borrower in respect of any L/C Related Document or any other amendment or waiver of or any consent to departure from all or any of the L/C Related Documents; (iii) the existence of any claim, set-off, defense or other right that the Borrower may have at any time against any beneficiary or any transferee of a Revolving Letter of Credit (or any Persons for which any such beneficiary or any such transferee may be acting), any Revolving Issuing Bank or any other Person, whether in connection

39 with the transactions contemplated by the L/C Related Documents or any unrelated transaction; (iv) any statement or any other document presented under a Revolving Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; (v) payment by any Revolving Issuing Bank under a Revolving Letter of Credit against presentation of a draft, certificate or other document that does not strictly comply with the terms of such Revolving Letter of Credit; (vi) any exchange, release or non-perfection of any Collateral or other collateral, or any release or amendment or waiver of or consent to departure from the Guarantees or any other guarantee, for all or any of the Obligations of the Borrower in respect of the L/C Related Documents; or (vii) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, including, without limitation, any other circumstance that might otherwise constitute a defense available to, or a discharge of, the Borrower or a guarantor. (h) Replacement of a Revolving Issuing Bank. (i) Any Revolving Issuing Bank may be replaced at any time by written agreement among the Borrower, the new Revolving Issuing Bank and the Administrative Agent (with notice to the Revolving Issuing Bank being replaced); provided, however, that, if the Revolving Issuing Bank being replaced so requests, any Revolving Letter of Credit issued by such Revolving Issuing Bank shall be replaced and cancelled prior to the removal of such Revolving Issuing Bank and all fees and other amounts owed to such removed Revolving Issuing Bank shall be paid to it by the Borrower; and provided, further, that the Initial Revolving Issuing Bank may not be replaced without the consent of the Required Lenders. (ii) If at any time the unsecured senior debt of any Revolving Issuing Bank (other than the Initial Revolving Issuing Bank or an Affiliate of the Initial Revolving Issuing Bank) is not rated at least A3 by Xxxxx’x and A- by S&P, then the Borrower may, upon 10 days’ prior written notice to such Revolving Issuing Bank and the Administrative Agent, elect to (i) replace such Revolving Issuing Bank with a Person selected by the Borrower so long as such Person is an Eligible Assignee and is reasonably satisfactory to the Administrative Agent or (ii) cause such Revolving Issuing Bank to assign its Letter of Credit Commitment to an additional Revolving Issuing Bank selected by the Borrower so long as such Person is an Eligible Assignee and is reasonably satisfactory to the Administrative Agent. Each replacement or assignment pursuant to this Section 2.03(h) shall be done in accordance with Section 9.07. (iii) From and after the effective date of any such replacement or addition, (A) the successor or additional Revolving Issuing Bank shall have all the rights and obligations of a Revolving Issuing Bank under this Agreement (and the Revolving

40 Letters of Credit to be issued by it on such effective date or thereafter) and (B) references herein to the term “Revolving Issuing Bank” shall be deemed to refer to such successor, additional Revolving Issuing Bank or to any previous Revolving Issuing Bank, or to such successor, additional Revolving Issuing Bank and all previous Issuing Banks, as the context may require. (i) Resignation of a Revolving Issuing Bank. Each Revolving Issuing Bank may at any time give notice of its resignation to the Administrative Agent and the Borrower, in each case by giving 30 days written notice thereof to such parties. Upon receipt of any such notice of resignation, the Borrower shall have the right, in consultation with the Administrative Agent, to appoint a successor, which shall be an Eligible Assignee and shall be reasonably satisfactory to the Administrative Agent, it being understood that each of Xxxxx Fargo, N.A., Deutsche Bank AG, Bank of America, N.A., Natixis New York and Barclays Bank PLC and their respective Affiliates or branches operating in New York (each a “Pre-Approved Issuing Bank”) is approved by and reasonably acceptable to both Borrower and the Administrative Agent.If no such successor shall have been so appointed by the Borrower and shall have accepted such appointment within 30 days after the retiring Revolving Issuing Bank gives notice of its resignation, then the retiring Revolving Issuing Bank may on behalf of the Revolving Credit Lenders, appoint a successor Revolving Issuing Bank, as applicable, meeting the qualifications set forth above; provided, that, if such Revolving Issuing Bank shall notify the Borrower and the Revolving Credit Lenders, that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and the retiring Revolving Issuing Bank shall be discharged from its duties and obligations hereunder and under the other Loan Documents. Upon the acceptance of a successor’s appointment as Revolving Issuing Bank hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Revolving Issuing Bank, and the retiring Revolving Issuing Bank shall be discharged from all of its duties and obligations to issue additional Revolving Letters of Credit hereunder without affecting its rights and obligations in respect to Revolving Letters of Credit previously issued by it (if not already discharged therefrom as provided above in this Section). After the resignation of the Revolving Issuing Bank hereunder, the retiring Revolving Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of a Revolving Issuing Bank set forth in this Agreement and the other Loan Documents with respect to Revolving Letters of Credit issued by it prior to such resignation, but shall not be required to issue additional Revolving Letters of Credit. (j) Revolving Letter of Credit Issuance Protocol. Notwithstanding any other provision of this Agreement, so long as Xxxx Bank USA or an Affiliate thereof is a Revolving Issuing Bank, the following protocol and agreements shall govern the issuance of all Revolving Letters of Credit by such Revolving Issuing Bank: (i) the Borrower shall use its commercially reasonable efforts to have the beneficiary of any requested Revolving Letter of Credit accept a Revolving Letter of Credit issued by Xxxx Bank USA or an Affiliate thereof; (ii) if the applicable beneficiary declines to accept a Revolving Letter of Credit issued by Xxxx Bank USA or an Affiliate thereof, then such Revolving Issuing

41 Bank agrees (A) to use its commercially reasonable efforts to cause Xxxxx Fargo Bank, N.A., Natixis New York, or another bank reasonably acceptable to the Borrower and such Revolving Issuing Bank to issue such Revolving Letter of Credit (i.e., front for such Revolving Issuing Bank) and (B) to the extent, in the manner and in the amount required by such bank, cash collateralize such Revolving Letter of Credit; (iii) in respect of any Revolving Letter of Credit issued by Xxxxx Fargo Bank, N.A., Natixis New York or another bank pursuant to clause (ii) or (iii) above (a “Fronting Bank”), (A) the letter of credit and fronting fees payable to the Fronting Bank for issuing such Revolving Letter of Credit shall be for the account of the Borrower, (B) the funds (if any) used to cash collateralize a Revolving Letter of Credit issued by a Fronting Bank shall be provided by such Revolving Issuing Bank, provided that any draw on any such Revolving Letter of Credit (and application or utilization of such funds by the Fronting Bank to reimburse itself for any such draw), and any loss of such funds by such Revolving Issuing Bank due to any cause whatsoever (except to the extent such loss and the amount of such loss are solely caused by breach of the Loan Documents or by acts of gross negligence or willful misconduct on the part of such Revolving Issuing Bank), shall give rise to a reimbursement obligation on the part of the Borrower to such Revolving Issuing Bank and a deemed advance by such Revolving Issuing Bank to be repaid by the Borrower to such Revolving Issuing Bank as if such amount had been drawn on the applicable Revolving Letter of Credit in accordance with Section 2.03(d), (C) unless otherwise agreed by the Borrower and such Revolving Issuing Bank, the Fronting Bank in its capacity as such shall have no rights or recourse against any Loan Party and shall not be a Secured Party or a Lender Party, (D) such Revolving Letter of Credit shall constitute a utilization of the applicable Revolving Letter of Credit Facility, and (E) the Borrower shall pay to such Revolving Issuing Bank the fees in respect of such Letter of Credit as if such Revolving Issuing Bank had issued such Revolving Letter of Credit pursuant to this Section 2.03; and (iv) a failure or delay by (A) any Fronting Bank to issue any Revolving Letter of Credit in accordance with the protocol set forth in this Section 2.03(j) or (B) any Revolving Issuing Bank or Fronting Bank to issue any Revolving Letter of Credit in the form requested by the Loan Parties shall not constitute a breach or default by such Revolving Issuing Bank of any of its obligations under this Agreement SECTION 2.04. Repayment of Loans. (a) Term B Loans. The Borrower shall repay to the Administrative Agent for the ratable account of the Term B Lenders the aggregate outstanding principal amount of the Term B Loans on the last Business Day of each of the following months in an amount equal to the product of (i) the aggregate principal amount of Term B Loans outstanding on the Effective Date (after giving effect to the Term B Borrowings on the Effective Date), multiplied by (ii) the percentage indicated opposite such month in the table below: Month Percentage June 2014 0.25%

(c) Revolving Letter of Credit Loans. The Borrower shall repay to the Administrative Agent for the account of the Revolving Issuing Bank and each Revolving Credit Lender that has made a Revolving Letter of Credit Loan on the Revolving Credit Termination Date the outstanding principal amount of each Revolving Letter of Credit Loan made by each of them. SECTION 2.05. Termination or Reduction of the Commitments. (a) Optional. The Borrower may, upon at least five Business Days’ written notice to the Administrative Agent, terminate in whole or reduce in part the Unused Revolving Credit Commitments; provided, however, that each partial reduction of the Revolving Credit Facility shall be in an aggregate amount of $5,000,000 or an integral multiple of $500,000 in excess thereof and shall be made ratably among the Revolving Credit Lenders in accordance with their Commitments with respect to the Revolving Credit Facility. The Borrower’s written notice to the Administrative Agent shall designate the date (which shall be a Business Day) of such termination or reduction and the amount of any partial reduction, and such termination or reduction of the relevant Commitments shall be effective on the date specified in the Borrower’s notice and shall reduce the relevant Commitments of the Appropriate Lenders proportionately in accordance with each such Appropriate Lender’s Pro Rata Share thereof.

(ii) Asset Sales. In addition, in the event of an Asset Sale, the Revolving Credit Commitments (and, if applicable, the corresponding Revolving Letter of Credit Commitments to the extent necessary so that such Revolving Letter of Credit Commitments will not exceed the reduced Revolving Credit Commitments) will be ratably and permanently reduced by the applicable amounts set forth below: (A) $25,000,000, in the event of a sale of the Millennium Project or Millennium; (B) $40,000,000, in the event of a Harquahala Sale; and (C) $100,000,000, in the event of a sale of the Athens Project or Athens.

(c) Yield Maintenance Fee. The Borrower will pay any Yield Maintenance Fee due in connection with any reduction of the Revolving Credit Commitments on the terms set forth in Section 2.08(b). SECTION 2.06. Prepayments. (a) Optional. The Borrower may, upon at least three Business Days’ notice to the Administrative Agent stating the proposed date and aggregate principal amount of the prepayment, and if such notice is given the Borrower shall, prepay the outstanding aggregate principal amount of the Loans in whole or ratably in part, together with accrued interest to the date of such prepayment on the aggregate principal amount prepaid and the applicable Yield Maintenance Fee (if any; it being understood that no Yield Maintenance Fee will be applicable with respect to prepayments of Revolving Credit Loans or Revolving Letter of Credit Loans that do not result in a permanent reduction of the Revolving Credit Commitments); provided, however, that (i) each partial prepayment shall be in an aggregate principal amount of $5,000,000 or an integral multiple of $500,000 in excess thereof and (ii) if any prepayment of a Loan is made on a date other than the last day of an Interest Period for such Loan, the Borrower shall also pay any amounts owing pursuant to Section 9.04(c). Each such prepayment of the Term B Loans shall be applied to scheduled principal payments of the Term B Loans in inverse order of maturity, including the principal amount due on the Term B Maturity Date. (b) Mandatory. (i) On each Cash Flow Payment Date, the Borrower shall prepay an aggregate principal amount of the Term B Loans in accordance with priority eighth of Section 3.2 of the Security Deposit Agreement and priority first of Section 3.7 of the Security Deposit Agreement, in an amount equal to seventy-five percent (75%) (subject to the provisos below, the “Cash Sweep Percentage”) of the aggregate amount remaining on deposit in or credited to the Revenue Account after giving effect to the withdrawals and transfers on such Cash Flow Payment Date pursuant to priorities first through seventh of Section 3.2 of the Security Deposit Agreement; provided, that if at least $150,000,000 of the outstanding aggregate principal amount of Term B Loans have been prepaid on or prior to July 10, 2016 solely from Cash Flow Available for Debt Service, the Cash Sweep Percentage shall be reduced to fifty percent (50%); provided, further, that if at least $225,000,000 of the outstanding aggregate principal amount of Term B Loans have been prepaid on or prior to July 10, 2018 solely from Cash Flow Available for Debt Service, the Cash Sweep Percentage shall be reduced to thirty- three percent (33%). Each such prepayment of the Term B Loans shall be applied to scheduled principal payments of the Term B Loans in inverse order of maturity (including the principal amount due on the Term B Maturity Date).

45 (ii) Subject to the Security Deposit Agreement, upon the occurrence of a Casualty Event, Event of Eminent Domain, Asset Sale or the incurrence or issuance of any Debt (other than Debt permitted to be incurred pursuant to Section 5.02(b)), the Borrower shall (A) prepay an aggregate principal amount of the Loans and (B) deposit an amount in the Revolving L/C Cash Collateral Account in an aggregate amount equal to the Net Cash Proceeds thereof in accordance with priorities first through third of Section 3.7 of the Security Deposit Agreement. Each such prepayment of the Term B Loans shall be applied to scheduled principal payments of the Term B Loans in inverse order of maturity, including the principal amount due on the Term B Maturity Date. (iii) [Reserved.] (iv) If at any time (A) the sum of the aggregate outstanding balance of the Revolving Credit Loans and the Available Amount of all Revolving Letters of Credit exceeds the aggregate Revolving Credit Commitments or (B) the Available Amount of all Revolving Letters of Credit exceeds the aggregate Revolving Letter of Credit Commitments, whether because of a reduction of the Revolving Credit Commitments and/or Revolving Letter of Credit Commitments pursuant to Section 2.05(b) or otherwise, the Borrower shall within two (2) Business Days, first, repay the Revolving Credit Loans and, second, if necessary, transfer funds to the Revolving L/C Cash Collateral Account in an amount sufficient to eliminate such excess in accordance with this Agreement. (v) All prepayments under this clause (b) shall be made together with (A) accrued and unpaid interest to the date of such prepayment on the principal amount prepaid, (B) any amounts owing pursuant to Section 9.04(c) and (C) any applicable Yield Maintenance Fee. (c) Term B Lender’s Option to Decline Prepayment. Except as provided in the last sentence of this clause (c), any Term B Lender, at its option, may elect not to accept all or any portion of any prepayment of the Term B Loans pursuant to Section 2.06(b). Subject to the immediately preceding sentence, upon each prepayment date set forth in Section 2.06(b) for any prepayment of Term B Loans, in accordance with the Security Deposit Agreement, the Borrower shall notify the Administrative Agent in writing of the amount that is available to prepay the Term B Loans. Promptly after the date of receipt of such notice, the Administrative Agent shall provide written notice (the “First Offer”) to the Term B Lenders of the amount available to prepay the Term B Loans. Any Term B Lender declining such prepayment (a “Declining Lender”) shall give written notice thereof to the Administrative Agent by 11:00 a.m. New York City time no later than two (2) Business Days after the date of such notice from the Administrative Agent; any Term B Lender that does not give such notice during such period shall be deemed to have accepted such prepayment offer. On such date the Administrative Agent shall then provide written notice (the “Second Offer”) to the Term B Lenders other than the Declining Lenders (such Term B Lenders being the “Accepting Lenders”) of the additional amount available (due to such Declining Lenders’ declining such prepayment) to prepay the Term B Loans owing to such Accepting Lenders. Any Term B Lender declining prepayment pursuant to such Second Offer shall give written notice thereof to the Administrative Agent by 11:00 a.m. New York City time no later than two (2) Business Days after the date of such notice of a Second Offer; any Term B Lender that does not give such notice during such period shall be

46 deemed to have accepted such prepayment offer. Amounts remaining after the allocation of accepted amounts shall be applied as provided in Section 3.7 of the Security Deposit Agreement, except to the extent otherwise set forth in Section 2.06(b). Notwithstanding the above, (A) if Term B Lenders owed or holding more than 50% of the aggregate principal amount of the Term B Loans outstanding at such time accept or are deemed to have accepted all or any portion of any prepayment offer pursuant to this clause (c), then all Term B Lenders shall be deemed to have accepted such prepayment offer to the same extent and (B) in the case of the mandatory prepayment of Term B Loans pursuant to Section 2.06(b) as a result of a Harquahala Sale, the right of the Term B Lenders to reject prepayments hereunder shall only be permitted once the Term B Loans have been prepaid with such proceeds such that the aggregate principal amount of the Term B Loans is $310,000,000 or less. SECTION 2.07. Interest. (a) Scheduled Interest. The Borrower shall pay interest on the unpaid principal amount of each Loan owing to each Lender from the date of such Loan until such principal amount shall be paid in full, at a rate per annum equal at all times during each Interest Period for such Loan to the sum of (A) the Eurodollar Rate for such Interest Period for such Loan plus (B) the Applicable Margin in effect from time to time, payable in arrears on each Interest Payment Date. (b) [Reserved]. (c) Default Interest. Upon the occurrence and during the continuance of an Event of Default, the Administrative Agent may, and upon the request of the Required Lenders shall, require that the Borrower pay interest (“Default Interest”) on (i) the unpaid principal amount of each Loan owing to each Lender Party, payable in arrears on the dates referred to in Section 2.07(a), as applicable, and on demand, at a rate per annum equal at all times to 2% per annum above the rate per annum required to be paid on such Loan pursuant to Section 2.07(a), as applicable, and (ii) to the fullest extent permitted by applicable law, the amount of any interest, fee or other amount payable under this Agreement or any other Loan Document to any Agent or any Lender Party that is not paid when due, from the date such amount shall be due until such amount shall be paid in full, payable in arrears on the date such amount shall be paid in full and on demand, at a rate per annum equal at all times to 2% per annum above the rate per annum required to be paid pursuant to Section 2.07(a); provided, however, that following the making of the request or the granting of the consent specified by Section 6.01 to authorize the Administrative Agent to declare the Loans due and payable pursuant to the provisions of Section 6.01, Default Interest shall accrue and be payable hereunder whether or not previously required by the Administrative Agent. Payment or acceptance of the increased rates of interest provided for in this Section 2.07(c) is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of the Administrative Agent or any Lender Party. SECTION 2.08. Fees. (a) Commitment Fee. The Borrower shall pay to the Administrative Agent for the account of each of the Revolving Credit Lenders, a commitment fee, from the date hereof in the case of each Initial Lender and from the effective date specified in the Assignment and Acceptance pursuant to which it became a Revolving Credit Lender in the case of each other

47 Revolving Credit Lender until the Revolving Credit Termination Date, payable in arrears quarterly on the last Business Day of each December, March, June and September occurring after the Effective Date, and on the Revolving Credit Termination Date, at the Eurodollar Rate per annum on the average daily Unused Revolving Credit Commitment of such Revolving Credit Lender during such quarter. (b) Yield Maintenance Fee. (i) Subject to clause (iii) below, upon any permanent reduction of the aggregate Revolving Credit Commitments pursuant to Section 2.05 or any termination of the aggregate Revolving Credit Commitments pursuant to Section 6.01 during the Yield Maintenance Period (the amount of such reduction being the "Commitment Reduction Amount" and the date when such reduction occurs being the "Commitment Reduction Date"), the Borrower shall pay to the Administrative Agent, for the ratable benefit of the Revolving Credit Lenders, a Yield Maintenance Fee in an amount equal to the Commitment Reduction Amount multiplied by the percentage set forth below opposite the period in which the Commitment Reduction Date occurs: Month Yield Maintenance Fee Percentage 11 April 2014 – 10 May 2014 5.86% 11 May 2014 – 10 June 2014 5.64% 11 June 2014 – 10 July 2014 5.43% 11 July 2014 – 10 August 2014 5.21% 11 August 2014 – 10 September 2014 4.99% 11 September 2014 – 10 October 2014 4.78% October 2014 – 10 November 2014 4.56% 11 November 2014 – 10 December 2014 4.34% 11 December 2014 – 10 January 2015 4.12% 11 January 2015 – 10 February 2015 3.91% 11 February 2015 – 10 March 2015 3.69% 11 March 2015 – 10 April 2015 3.47% 11 April 2015 – 10 May 2015 3.26%

48 11 May 2015 – 10 June 2015 3.04% 11 June 2015 – 10 July 2015 2.82% 11 July 2015 – 10 August 2015 2.60% 11 August 2015 – 10 September 2015 2.39% 11 September 2015 – 10 October 2015 2.17% 11 October 2015 – 10 November 2015 1.95% 11 November 2015 – 10 December 2015 1.74% 11 December 2015 – 10 January 2016 1.52% 11 January 2016 – 10 February 2016 1.30% 11 February 2016 – 10 March 2016 1.09% 11 March 2016 – 10 April 2016 0.87% 11 April 2016 – 10 May 2016 0.65% 11 May 2016 – 10 June 2016 0.43% 11 June 2016 – 10 July 2016 0.22% After 10 July 2016 0.00% (ii) Subject to clause (iii) below, in the event that (A) the Borrower makes any prepayment of Term B Loans pursuant to Section 2.06 other than any prepayment upon the occurrence of a Casualty Event or an Event of Eminent Domain or (B) the unpaid principal balance of any Term B Loan is accelerated pursuant to Section 6.01 during the Yield Maintenance Period (the principal amount of such prepayment or amount so accelerated being the “Prepayment Amount”), the Borrower shall pay to the Administrative Agent, for the ratable benefit of the Term B Lenders, a Yield Maintenance Fee in an amount equal to the sum of the interest that would have been payable on the Prepayment Amount (in the absence of such prepayment or acceleration) at a rate per annum equal to the Applicable Margin (x) on all scheduled Interest Payment Dates falling after the date of prepayment or acceleration until the end of the Yield Maintenance Period and (y) if the last day of the Yield Maintenance Period is not an Interest Payment Date, on the last day of the Yield Maintenance Period, in each case discounted from the respective scheduled payment date to the date of prepayment or acceleration, in accordance with accepted financial practice at a discount factor equal to

49 the equivalent weighted-average life U.S. Treasury yield as of 10:00 a.m. New York City time on the Business Day immediately preceding the date of prepayment or acceleration. (iii) Notwithstanding anything set forth in this Agreement, no Yield Maintenance Fee will be due: (A) with respect to any prepayment of the Loans or reduction of Revolving Credit Commitments, in each case, resulting from a Harquahala Sale; (B) following the end of the Yield Maintenance Period; provided, however, that, in the event of an acceleration of the Facilities pursuant to Section 6.01 or Section 6.02, the Yield Maintenance Fee shall apply and shall be determined pursuant to clause (b)(ii) above as if a prepayment occurred on the date of such acceleration; (C) with respect to any payment of Revolving Credit Loans or Revolving Letter of Credit Loans that does not result in a permanent reduction of the Revolving Credit Commitments; (D) [Reserved]; or (E) with respect to any reduction of Revolving Credit Commitments pursuant to Section 2.05(b)(iii). (c) Revolving Letter of Credit Fees. (i) The Borrower shall pay to the Administrative Agent for the account of each Revolving Credit Lender a letter of credit fee, payable in arrears quarterly on the last Business Day of each December, March, June and September occurring after the Effective Date, and on the Revolving Credit Termination Date, on such Revolving Credit Lender’s Pro Rata Share of the average daily aggregate Available Amount during such quarter of all Revolving Letters of Credit outstanding from time to time during such quarter at a rate per annum equal to the Eurodollar Rate plus 2.00%. (ii) The Borrower shall pay the Revolving Issuing Bank, for its own account, such commissions, issuance fees, fronting fees, transfer fees and other fees and charges in connection with the issuance, administration and amendment of each Revolving Letter of Credit as the Borrower and such Revolving Issuing Bank shall agree. (d) Agents’ Fees. The Borrower shall pay to each Agent for its own account such fees as may from time to time be agreed between the Borrower and such Agent. SECTION 2.09. [Reserved]. SECTION 2.10. Increased Costs, Etc. (a) If, due to either (i) the introduction of or any change in or in the interpretation of any law or regulation or (ii) the compliance with any guideline or request from any central bank or other governmental authority (whether or not having the force of law), there shall be any increase in the cost to any Lender Party of agreeing to make or of making, funding or maintaining Loans or of agreeing to issue or of issuing or

50 maintaining or participating in Revolving Letters of Credit or of agreeing to make or of making or maintaining Revolving Letter of Credit Loans (excluding, for purposes of this Section 2.10, any such increased costs resulting from (x) Taxes or Other Taxes (as to which Section 2.12 shall govern) and (y) changes in the basis or rate of taxation of overall net income or overall gross income by the United States or by the foreign jurisdiction or state under the laws of which such Lender Party is organized or has its Lending Office or any political subdivision thereof), then the Borrower shall from time to time, upon demand by such Lender Party (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender Party additional amounts sufficient to compensate such Lender Party for such increased cost. A certificate as to the amount of such increased cost, submitted to the Borrower by such Lender Party, shall be conclusive and binding for all purposes, absent manifest error. (b) If any Lender Party determines that compliance with any law or regulation or any guideline or request from any central bank or other governmental authority (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Lender Party or any corporation controlling such Lender Party and that the amount of such capital is increased by or based upon the existence of such Lender Party’s commitment to make Loans or to issue or participate in Revolving Letters of Credit hereunder and other commitments of such type or the issuance or maintenance of or participations in the Revolving Letters of Credit (or similar Guaranteed Debts), then, upon demand by such Lender Party or such corporation (with a copy of such demand to the Administrative Agent), the Borrower shall pay to the Administrative Agent for the account of such Lender Party, from time to time as specified by such Lender Party, additional amounts sufficient to compensate such Lender Party in the light of such circumstances, to the extent that such Lender Party reasonably determines such increase in capital to be allocable to the existence of such Lender Party’s commitment to make Loans or to issue or participate in Revolving Letters of Credit hereunder or to the issuance or maintenance of or participation in any Revolving Letters of Credit. A certificate as to such amounts submitted to the Borrower by such Lender Party shall be conclusive and binding for all purposes, absent manifest error. SECTION 2.11. Payments and Computations. (a) The Borrower shall make each payment hereunder and under the other Loan Documents, irrespective of any right of counterclaim or set-off (except as otherwise provided in Section 2.13), not later than 11:00 A.M. (New York City time) on the day when due in U.S. dollars to the Administrative Agent at the Administrative Agent’s Account in same day funds, with payments being received by the Administrative Agent after such time being deemed to have been received on the next succeeding Business Day. The Administrative Agent will promptly thereafter cause like funds to be distributed (i) if such payment by the Borrower is in respect of principal, interest, commitment fees or any other Obligation then payable hereunder and under the other Loan Documents to more than one Lender Party, to such Lender Parties for the account of their respective Lending Offices ratably in accordance with the amounts of such respective Obligations then payable to such Lender Parties and (ii) if such payment by the Borrower is in respect of any Obligation then payable hereunder to one Lender Party, to such Lender Party for the account of its Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Acceptance and recording of the information contained therein in the Register pursuant to Section 9.07(e), from and after the effective date of such Assignment and Acceptance, the Administrative Agent shall make all

51 payments hereunder and under the other Loan Documents in respect of the interest assigned thereby to the assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves. (b) The Borrower hereby authorizes each Lender Party and each of its Affiliates, if and to the extent payment owed to such Lender Party is not made when due hereunder or under the other Loan Documents to charge from time to time, to the fullest extent permitted by law, against any or all of the Borrower’s accounts with such Lender Party or such Affiliate any amount so due. (c) All computations of interest based on the Eurodollar Rate and of commitment fees, letter of credit fees and other fees and commissions shall be made by the Administrative Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest, fees or commissions are payable. Each determination by the Administrative Agent of an interest rate, fee or commission hereunder shall be conclusive and binding for all purposes, absent manifest error. (d) Whenever any payment hereunder or under the other Loan Documents shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or commitment or letter of credit fee or commission, as the case may be; provided, however, that, if such extension would cause payment of interest on or principal of Loans to be made in the next following calendar month, such payment shall be made on the preceding Business Day. (e) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to any Lender Party hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each such Lender Party on such due date an amount equal to the amount then due such Lender Party. If and to the extent the Borrower shall not have so made such payment in full to the Administrative Agent, each such Lender Party shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender Party together with interest thereon, for each day from the date such amount is distributed to such Lender Party until the date such Lender Party repays such amount to the Administrative Agent, at the Eurodollar Rate. (f) If the Administrative Agent receives funds for application to the Obligations of the Loan Parties under or in respect of the Loan Documents under circumstances for which the Loan Documents do not specify the Loans or the Facility to which, or the manner in which, such funds are to be applied, the Administrative Agent may, if no instructions with respect thereto are received from the Lender Parties upon request, but shall not be obligated to, elect to distribute such funds to each of the Lender Parties in accordance with such Lender Parties pro rata share of the sum of (i) the aggregate principal amount of all Loans outstanding at such time and (ii) the aggregate Available Amount of all Revolving Letters of Credit outstanding

52 at such time, in repayment or prepayment of such of the outstanding Loans or other Obligations then owing to such Lender Party, and, in the case of the Term B Facility, for application to such principal repayment installments thereof, as the Administrative Agent shall direct. (g) Notwithstanding any provision of this Agreement to the contrary, to the extent that this Agreement provides for advances or payments (or deemed advances or payments) to be made by or to the Revolving Credit Lenders ratably according to their Revolving Credit Commitments or according to their Pro Rata Shares, as between Xxxx Bank USA and Xxxx Bank, SSB, the Revolving Credit Lenders may allocate such advances and payments ratably according to their respective Unused Revolving Credit Commitments or in such other manner as Xxxx Bank USA and Xxxx Bank, SSB may agree without affecting in any manner the aggregate Revolving Credit Commitments available to the Borrower at any time. SECTION 2.12. Taxes. (a) Any and all payments by any Loan Party to or for the account of any Lender Party or any Agent hereunder or under any other Loan Document shall be made, in accordance with Section 2.11 or the applicable provisions of such other Loan Document, if any, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender Party and each Agent, taxes that are imposed on its overall net income by the United States and taxes that are imposed on its overall net income (and franchise taxes imposed in lieu thereof) by the state or foreign jurisdiction under the laws of which such Lender Party or such Agent, as the case may be, is organized (or any political subdivision thereof), has its Lending Office, has a permanent establishment or is engaged in business (other than the business that the Lender Party is engaged in solely by reason of the transactions contemplated by this Agreement), (y) any branch profits taxes imposed by the United States of America and (z) withholding taxes imposed under law in effect on the date hereof or at the time the Lender Party designates a new Lending Office, other than any new Lending Office designated at the written request of a Loan Party (in the case of a Lender Party that is not an Initial Lender, this clause (z) shall include taxes imposed under law in effect on the date such Lender Party becomes a Lender Party, except to the extent that the Lender’s predecessor would have been entitled to receive additional amounts under this Section 2.12(a)) and, in the case of each Lender Party, taxes that are imposed on its overall net income (and franchise taxes imposed in lieu thereof) by the state or foreign jurisdiction of such Lender Party’s Lending Office or any political subdivision thereof (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities in respect of payments hereunder or under any other Loan Document being hereinafter referred to as “Taxes”). If any Loan Party shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any other Loan Document to any Lender Party or any Agent, (i) the sum payable by such Loan Party shall be increased as may be necessary so that after such Loan Party and the Administrative Agent have made all required deductions (including deductions applicable to additional sums payable under this Section 2.12) such Lender Party or such Agent, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made, (ii) such Loan Party shall make all such deductions and (iii) such Loan Party shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law. (b) In addition, each Loan Party shall pay any present or future stamp, documentary, excise, property (including intangible property, but with regard to all property

53 taxes, only to the extent relating to property of a Loan Party) mortgage recording or similar taxes, charges or levies that arise from any payment made by such Loan Party hereunder or under any other Loan Documents or from the execution, delivery or registration of, performance under, or otherwise with respect to, this Agreement or the other Loan Documents (hereinafter referred to as “Other Taxes”). (c) The Loan Parties shall indemnify each Lender Party and each Agent for and hold them harmless against the full amount of Taxes and Other Taxes, and for the full amount of taxes of any kind imposed or asserted by any jurisdiction on amounts payable under this Section 2.12, imposed on or paid by such Lender Party or such Agent (as the case may be) and any liability (including penalties, additions to tax, interest and expenses) arising therefrom or with respect thereto. This indemnification shall be made within 30 days from the date such Lender Party or such Agent (as the case may be) makes written demand therefor. (d) Within 30 days after the date of any payment of Taxes, the appropriate Loan Party shall furnish to the Administrative Agent, at its address referred to in Section 9.02, the original or a certified copy of a receipt evidencing such payment, to the extent such a receipt is issued therefor, or other written proof of payment thereof that is reasonably satisfactory to the Administrative Agent. In the case of any payment hereunder or under the other Loan Documents by or on behalf of a Loan Party through an account or branch outside the United States or by or on behalf of a Loan Party by a payor that is not a United States person, if such Loan Party determines that no Taxes are payable in respect thereof, such Loan Party shall furnish, or shall cause such payor to furnish, to the Administrative Agent, at such address, an opinion of counsel acceptable to the Administrative Agent stating that such payment is exempt from Taxes. For purposes of subsections (d) and (e) of this Section 2.12, the terms “United States” and “United States person” shall have the meanings specified in Section 7701 of the Internal Revenue Code. (e) Each Lender Party organized under the laws of a jurisdiction outside the United States shall, on or prior to the date of its execution and delivery of this Agreement in the case of each Initial Lender Party and on the date of the Assignment and Acceptance pursuant to which it becomes a Lender Party in the case of each other Lender Party, and from time to time thereafter as reasonably requested in writing by the Borrower (but only so long thereafter as such Lender Party remains lawfully able to do so), provide each of the Administrative Agent and the Borrower with two original Internal Revenue Service Forms W-8BEN or W-8EC1 or (in the case of a Lender Party that has certified in writing to the Administrative Agent that it is not (i) a “bank” as defined in Section 881(c)(3)(A) of the Internal Revenue Code), (ii) a 10-percent shareholder (within the meaning of Section 871(h)(3)(B) of the Internal Revenue Code) of any Loan Party or (iii) a controlled foreign corporation related to any Loan Party (within the meaning of Section 864(d)(4) of the Internal Revenue Code), Internal Revenue Service Form W-8BEN, as appropriate, or any successor or other form prescribed by the Internal Revenue Service, certifying that such Lender Party is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to this Agreement or any other Loan Document or, in the case of a Lender Party that has certified that it is not a “bank” as described above, certifying that such Lender Party is a foreign corporation, partnership, estate or trust. As provided in Section 2.12(a), if the forms provided by a Lender Party at the time such Lender Party first becomes a party to this Agreement indicate a United States interest withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from Taxes unless and

54 until such Lender Party provides the appropriate forms certifying that a lesser rate applies, whereupon withholding tax at such lesser rate only shall be considered excluded from Taxes for periods governed by such forms; provided, however, that if, at the effective date of the Assignment and Acceptance pursuant to which a Lender Party becomes a party to this Agreement, the Lender Party assignor was entitled to payments under subsection (a) of this Section 2.12 in respect of United States withholding tax with respect to interest paid at such date, then, to such extent, the term Taxes shall include (in addition to withholding taxes that may be imposed in the future or other amounts otherwise includable in Taxes) United States withholding tax, if any, applicable with respect to the Lender Party assignee on such date. If any form or document referred to in this subsection (e) requires the disclosure of information, other than information necessary to compute the tax payable and information required on the date hereof by Internal Revenue Service Form W-8BEN or W-8EC1 or the related certificate described above, that the applicable Lender Party reasonably considers to be confidential, such Lender Party shall give notice thereof to the Borrower and shall not be obligated to include in such form or document such confidential information. (f) For any period with respect to which a Lender Party has failed to provide the Borrower with the appropriate form, certificate or other document described in subsection (e) above (other than if such failure is due to a change in law, or in the interpretation or application thereof, occurring after the date on which a form, certificate or other document originally was required to be provided or if such form, certificate or other document otherwise is not required under subsection (e) above), such Lender Party shall not be entitled to indemnification under subsection (a) or (c) of this Section 2.12 with respect to Taxes imposed by the United States by reason of such failure; provided, however, that should a Lender Party become subject to Taxes because of its failure to deliver a form, certificate or other document required hereunder, the Loan Parties shall take such steps as such Lender Party shall reasonably request, at the Lender Party’s sole expense and as long as the Loan Parties determine that such steps will not, in the reasonable judgment of the Loan Parties, be disadvantageous to the Loan Parties, to assist such Lender Party to recover such Taxes. (g) Any Lender Party claiming any additional amounts payable pursuant to this Section 2.12 agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Lending Office if the making of such a change would avoid the need for, or reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the reasonable judgment of such Lender Party, be otherwise disadvantageous to such Lender Party. In addition, if a Lender Party determines, in such Lender Party’s sole discretion, that it has received a refund or credit in respect of any Taxes or Other Taxes as to which it has been indemnified pursuant to Section 2.12(c), or with respect to which additional amounts have been paid pursuant to Section 2.12(a), such Lender Party shall pay to the Borrower an amount equal to such refund (but such amount in no event to exceed the amount of any indemnity payments made, or additional amounts paid, by the Borrower under this Section 2.12 with respect to the Taxes or Other Taxes giving rise to such refund) net of all out- of-pocket expenses of such Lender Party, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund), provided that the Borrower, upon the request of such Lender Party, shall agree to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to such Lender Party in the event such Lender Party subsequently determines that such refund or credit is

55 unavailable under applicable law or is otherwise required to repay such refund to such Governmental Authority. This paragraph shall not be construed to require a Lender Party to rearrange its tax affairs or to make available its tax returns (or any other information relating to its taxes that it deems confidential) to the Borrower or any other Person. SECTION 2.13. Sharing of Payments, Etc. If any Lender Party shall obtain at any time any payment (whether voluntary, involuntary, through the exercise of any right of set- off, or otherwise, other than as a result of an assignment pursuant to Section 9.07), (a) on account of Obligations due and payable to such Lender Party hereunder and under the other Loan Documents in excess of its ratable share (according to the proportion of the amount of such Obligations due and payable to such Lender Party, (ii) the aggregate amount of the Obligations due and payable to all Lender Parties hereunder and under the other Loan Documents at such time) of payments on account of the Obligations due and payable to all Lender Parties hereunder and under the other Loan Documents at such time obtained by all the Lender Parties at such time or (b) on account of Obligations owing (but not due and payable) to such Lender Party hereunder and under the other Loan Documents at such time in excess of its ratable share (according to the proportion of (i) the amount of such Obligations owing to such Lender Party at such time to (ii) the aggregate amount of the Obligations owing (but not due and payable) to all Lender Parties hereunder and under the other Loan Documents at such time) of payments on account of the Obligations owing (but not due and payable) to all Lender Parties hereunder and under the other Loan Documents at such time obtained by all of the Lender Parties at such time, such Lender Party shall forthwith purchase from the other Lender Parties such interests or participating interests in the Obligations as shall be necessary to cause such purchasing Lender Party to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender Party, such purchase from each other Lender Party shall be rescinded and such other Lender Party shall repay to the purchasing Lender Party the purchase price to the extent of such Lender Party’s ratable share (according to the proportion of (i) the purchase price paid to such Lender Party to (ii) the aggregate purchase price paid to all Lender Parties) of such recovery together with an amount equal to such Lender Party’s ratable share (according to the proportion of (i) the amount of such other Lender Party’s required repayment to (ii) the total amount so recovered from the purchasing Lender Party) of any interest or other amount paid or payable by the purchasing Lender Party in respect of the total amount so recovered.

For the avoidance of doubt, notwithstanding anything to the contrary in this Section 2.13 or otherwise, the Lender Parties shall not be entitled to receive or share in any fees paid by the Borrower pursuant to Section 2.08(c), which fees shall be solely for the account of the Revolving Credit Lenders (with respect to Section 2.08(c)(i)) and Revolving Issuing Bank (with respect to Section 2.08(c)(ii)).

No Agent shall have any duty to disclose any information obtained or received by it or any of its Affiliates relating to any Loan Party or any of its Subsidiaries to the extent such information was obtained or received in any capacity other than as such Agent. SECTION 7.04. Lender Party Credit Decision.

In the case of any investigation, litigation or proceeding giving rise to any Indemnified Costs, this Section 7.05 applies whether any such investigation, litigation or proceeding is brought by any Lender Party or any other Person. Each Agent is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and otherwise apply any and all amounts it receives pursuant to the Loan Documents to or for the credit or the account of any Lender Party against any and all obligations of such Lender Party to such Agent now or hereafter existing under this Section 7.05; provided that the foregoing sentence shall only apply if such Lender Party fails to promptly pay such obligation following such Agent’s written request for

90 payment; provided further that any obligation a Lender Party fails to promptly pay following the Agent’s written request for payment shall bear interest at the same rate as Default Interest and the Agent is authorized to set off against any such accrued interest in the manner described above. (b) Each Revolving Credit Lender severally agrees to indemnify the Revolving Issuing Bank (to the extent not promptly reimbursed by the Borrower) from and against such Lender Party’s ratable share (determined as provided below) of any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against such Revolving Issuing Bank in any way relating to or arising out of the Loan Documents or any action taken or omitted by such Revolving Issuing Bank under the Loan Documents; provided, however, that no Lender Party shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from such Revolving Issuing Bank’s gross negligence or willful misconduct as found in a final, non-appealable judgment by a court of competent jurisdiction. Without limitation of the foregoing, each Revolving Credit Lender agrees to reimburse the Revolving Issuing Bank promptly upon demand for its ratable share of any costs and expenses (including, without limitation, fees and expenses of counsel) payable by the Borrower under Section 9.04, to the extent that such Revolving Issuing Bank is not promptly reimbursed for such costs and expenses by the Borrower. (c) For purposes of Section 7.05(a), (i) each Lender Party’s ratable share of any amount shall be determined, at any time, according to the sum of (A) the aggregate principal amount of the Loans outstanding at such time and owing to such Lender Party, (B) in the case of any Revolving Credit Lender, such Revolving Credit Lender’s Unused Revolving Credit Commitments at such time and (C) in the case of any Revolving Credit Lender, such Revolving Credit Lender’s Pro Rata Shares of the aggregate Available Amount of all Revolving Letters of Credit outstanding at such time; and (ii) each Revolving Credit Lender’s ratable share of any amount shall be determined, at any time, according to the sum of (A) the aggregate principal amount of the Revolving Credit Loans outstanding at such time and owing to such Lender, (B) such Lender’s Pro Rata Shares of the aggregate Available Amount of all Revolving Letters of Credit outstanding at such time and (C) such Lender’s Unused Revolving Credit Commitments at such time; provided that the aggregate principal amount of Revolving Letter of Credit Loans owing to the Revolving Issuing Bank shall be considered to be owed to the Revolving Credit Lenders ratably in accordance with their respective Revolving Credit Commitments and Section 7.05(b). The failure of any Lender Party to reimburse any Agent or any Revolving Issuing Bank, as the case may be, promptly upon demand for its ratable share of any amount required to be paid by the Lender Parties to the such Agent or such Revolving Issuing Bank, as the case may be, as provided herein shall not relieve any other Lender Party of its obligation hereunder to reimburse such Agent or Revolving Issuing Bank, as the case may be, for its ratable share of such amount, but no Lender Party shall be responsible for the failure of any other Lender Party to reimburse such Agent or Revolving Issuing Bank, as the case may be, for such other Lender Party’s ratable share of such amount. Without prejudice to the survival of any other agreement of any Lender Party hereunder, the agreement and obligations of each Lender Party contained in this Section 7.05 shall survive the payment in full of principal, interest and all other amounts payable hereunder and under the other Loan Documents.

91 SECTION 7.06. Successor Administrative Agent. The Administrative Agent may resign as to any or all of the Facilities at any time by giving 15 days’ written notice thereof to the Lender Parties and the Borrower and may be removed at any time with or without cause by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the right, with (so long as no Event of Default has occurred and is continuing) the consent of the Borrower (not to be unreasonably withheld or delayed), to appoint a successor Administrative Agent as to such of the Facilities as to which the Administrative Agent has resigned or been removed. If no successor Administrative Agent shall have been so appointed by the Required Lenders, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s giving of notice of resignation or the Required Lenders’ removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lender Parties, appoint a successor Administrative Agent, which shall be a commercial bank organized under the laws of the United States or of any State thereof and having a combined capital and surplus of at least $500,000,000. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall succeed to and become vested with all the rights, powers, discretion, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations under the Loan Documents. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent as to less than all of the Facilities, such successor Administrative Agent shall succeed to and become vested with all the rights, powers, discretion, privileges and duties of the retiring Administrative Agent as to such Facilities, other than with respect to funds transfers and other similar aspects of the administration of Borrowings under such Facilities, issuance of Revolving Letters of Credit (notwithstanding any resignation as Administrative Agent with respect to the Revolving Letter of Credit Facility) and payments by the Borrower in respect of such Facilities, and the retiring Administrative Agent shall be discharged from its duties and obligations under this Agreement as to such Facilities, other than as aforesaid. If within 45 days after written notice is given of the retiring Administrative Agent’s resignation or removal under this Section 7.06 no successor Administrative Agent shall have been appointed and shall have accepted such appointment, then on such 45th day (a) the retiring Administrative Agent’s resignation or removal shall become effective, (b) the retiring Administrative Agent shall thereupon be discharged from its duties and obligations under the Loan Documents and (c) the Required Lenders shall thereafter perform all duties of the retiring Administrative Agent under the Loan Documents until such time, if any, as the Required Lenders appoint a successor Agent as provided above. After any retiring Administrative Agent’s resignation or removal hereunder as Administrative Agent as to any of the Facilities shall have become effective, the provisions of this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent as to such Facilities under this Agreement. SECTION 7.07. First Lien Collateral Agent. Each of the Administrative Agent and the Lender Parties hereby designates and appoints CLMG as First Lien Collateral Agent under this Agreement and the other Loan Documents and authorizes CLMG, in the capacity of First Lien Collateral Agent, to (A) execute, deliver and perform the obligations, if any, of the First Lien Collateral Agent, as applicable under this Agreement and each other Loan Document and (B) take such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such duties as are expressly delegated to the First Lien Collateral Agent by the terms of this Agreement and the other Loan Documents,

92 together with such other powers as are reasonably incidental thereto; provided, however, that the First Lien Collateral Agent shall not be required to take any action that exposes the First Lien Collateral Agent to personal liability or that is contrary to this Agreement or applicable law. Without limiting the generality of the foregoing, each of the Administrative Agent and the Lender Parties hereby authorizes and instructs CLMG, in the capacity of First Lien Collateral Agent, to execute and deliver the documents to be entered into by the First Lien Collateral Agent expressly mentioned in Section 3.01, and, without limiting any of the provisions of this Agreement, CLMG, in the capacity of First Lien Collateral Agent, shall continue to be bound by and entitled to all the benefits and protections afforded to the First Lien Collateral Agent under the Intercreditor Agreement, including Section 7 of the Intercreditor Agreement, as if fully set forth herein. ARTICLE VIII GUARANTY SECTION 8.01. Guaranty; Limitation of Liability. (a) Subject in the case of Athens to the Athens Cap Amount, each Guarantor, jointly and severally, hereby absolutely, unconditionally and irrevocably guarantees the punctual payment when due, whether at scheduled maturity or on any date of a required prepayment or by acceleration, demand or otherwise, of all Obligations of each other Loan Party now or hereafter existing under or in respect of the Loan Documents (including, without limitation, any extensions, modifications, substitutions, amendments or renewals of any or all of the foregoing Obligations), whether direct or indirect, absolute or contingent, and whether for principal, interest, premiums, fees, indemnities, contract causes of action, costs, expenses or otherwise (such Obligations being the “Guaranteed Obligations”), and agrees to pay any and all expenses (including, without limitation, reasonable fees and expenses of counsel) incurred by the Administrative Agent or any other Lender Party in enforcing any rights under this Guaranty or any other Loan Document. Without limiting the generality of the foregoing, subject in the case of Athens to the Athens Cap Amount, each Guarantor’s liability shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by any other Loan Party to any Lender Party under or in respect of the Loan Documents but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving such other Loan Party. (b) Each Guarantor, and by its acceptance of this Guaranty, the Administrative Agent and each other Lender Party, hereby confirms that it is the intention of all such Persons that this Guaranty and the obligations of each Guarantor hereunder not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar foreign, federal or state law to the extent applicable to this Guaranty and the obligations of each Guarantor hereunder. To effectuate the foregoing intention, the Administrative Agent, the other Lender Parties and the Guarantors hereby irrevocably agree that the obligations of each Guarantor under this Guaranty at any time shall be limited to the maximum amount as will result in the obligations of such Guarantor under this Guaranty not constituting a fraudulent transfer or conveyance.

93 (c) Subject in the case of Athens to the Athens Cap Amount, each Guarantor hereby unconditionally and irrevocably agrees that in the event any payment shall be required to be made to any Lender Party under this Guaranty or any other guaranty, such Guarantor will contribute, to the maximum extent permitted by law, such amounts to each other Guarantor and each other guarantor so as to maximize the aggregate amount paid to the Lender Parties under or in respect of the Loan Documents. SECTION 8.02. Guaranty Absolute. Subject in the case of Athens to the Athens Cap Amount, each Guarantor guarantees that the Guaranteed Obligations will be paid strictly in accordance with the terms of the Loan Documents, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of any Lender Party with respect thereto. The obligations of each Guarantor under or in respect of this Guaranty are independent of the Guaranteed Obligations or any other Obligations of any other Loan Party under or in respect of the Loan Documents, and a separate action or actions may be brought and prosecuted against each Guarantor to enforce this Guaranty, irrespective of whether any action is brought against the Borrower or any other Loan Party or whether the Borrower or any other Loan Party is joined in any such action or actions. The liability of each Guarantor under this Guaranty shall be irrevocable, absolute and unconditional irrespective of, and each Guarantor hereby irrevocably waives any defenses it may now have or hereafter acquire in any way relating to, any or all of the following: (a) any lack of validity or enforceability of any Loan Document or any agreement or instrument relating thereto; (b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Guaranteed Obligations or any other Obligations of any other Loan Party under or in respect of the Loan Documents, or any other amendment or waiver of or any consent to departure from any Loan Document, including, without limitation, any increase in the Guaranteed Obligations resulting from the extension of additional credit to any Loan Party or any of its Subsidiaries or otherwise; (c) any taking, exchange, release or non-perfection of any Collateral or any other collateral, or any taking, release or amendment or waiver of, or consent to departure from, any other guaranty, for all or any of the Guaranteed Obligations; (d) any manner of application of Collateral or any other collateral, or proceeds thereof, to all or any of the Guaranteed Obligations, or any manner of sale or other disposition of any Collateral or any other collateral for all or any of the Guaranteed Obligations or any other Obligations of any Loan Party under the Loan Documents or any other assets of any Loan Party or any of its Subsidiaries; (e) any change, restructuring or termination of the corporate structure or existence of any Loan Party or any of its Subsidiaries; (f) any failure of any Lender Party to disclose to any Loan Party any information relating to the business, condition (financial or otherwise), operations, performance,

94 properties or prospects of any other Loan Party now or hereafter known to such Lender Party (each Guarantor waiving any duty on the part of the Lender Parties to disclose such information); (g) the failure of any other Person to execute or deliver this Agreement or any other guaranty or agreement or the release or reduction of liability of any Guarantor or other guarantor or surety with respect to the Guaranteed Obligations; or (h) any other circumstance (including, without limitation, any statute of limitations) or any existence of or reliance on any representation by any Lender Party that might otherwise constitute a defense available to, or a discharge of, any Loan Party or any other guarantor or surety. This Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed Obligations is rescinded or must otherwise be returned by any Lender Party or any other Person upon the insolvency, bankruptcy or reorganization of the Borrower or any other Loan Party or otherwise, all as though such payment had not been made. SECTION 8.03. Waivers and Acknowledgments. (a) Each Guarantor hereby unconditionally and irrevocably waives promptness, diligence, notice of acceptance, presentment, demand for performance, notice of nonperformance, default, acceleration, protest or dishonor and any other notice with respect to any of the Guaranteed Obligations and this Guaranty and any requirement that any Lender Party protect, secure, perfect or insure any Lien or any property subject thereto or exhaust any right or take any action against any Loan Party or any other Person or any Collateral. (b) Each Guarantor hereby unconditionally and irrevocably waives any right to revoke this Guaranty and acknowledges that this Guaranty is continuing in nature and applies to all Guaranteed Obligations, whether existing now or in the future. (c) Each Guarantor hereby unconditionally and irrevocably waives (i) any defense arising by reason of any claim or defense based upon an election of remedies by any Lender Party that in any manner impairs, reduces, releases or otherwise adversely affects the subrogation, reimbursement, exoneration, contribution or indemnification rights of such Guarantor or other rights of such Guarantor to proceed against any of the other Loan Parties, any other guarantor or any other Person or any Collateral and (ii) any defense based on any right of set-off or counterclaim against or in respect of the obligations of such Guarantor hereunder. (d) Each Guarantor acknowledges that the First Lien Collateral Agent may, without notice to or demand upon such Guarantor and without affecting the liability of such Guarantor under this Guaranty, foreclose under any mortgage by nonjudicial sale, and each Guarantor hereby waives any defense to the recovery by the First Lien Collateral Agent and the other First Lien Secured Parties against such Guarantor of any deficiency after such nonjudicial sale and any defense or benefits that may be afforded by applicable law. (e) Each Guarantor hereby unconditionally and irrevocably waives any duty on the part of any Lender Party to disclose to such Guarantor any matter, fact or thing relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of any other Loan Party or any of its Subsidiaries now or hereafter known by such Lender Party.

95 (f) Each Guarantor acknowledges that it will receive substantial direct and indirect benefits from the financing arrangements contemplated by the Loan Documents and that the waivers set forth in Section 8.02 and this Section 8.03 are knowingly made in contemplation of such benefits. SECTION 8.04. Subrogation. Each Guarantor hereby unconditionally and irrevocably agrees not to exercise any rights that it may now have or hereafter acquire against the Borrower or any other Loan Party that arise from the existence, payment, performance or enforcement of such Guarantor’s obligations under or in respect of this Guaranty or any other Loan Document, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of any Lender Party against the Borrower, any other Loan Party or any Collateral, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from the Borrower or any other Loan Party directly or indirectly, in Cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right, unless and until all of the Guaranteed Obligations and all other amounts payable under this Guaranty shall have been paid in full in Cash, all Revolving Letters of Credit shall be expired or been terminated and the Commitments shall have expired or been terminated. If any amount shall be paid to any Guarantor in violation of the immediately preceding sentence at any time prior to the latest of (a) the payment in full in Cash of the Guaranteed Obligations and all other amounts payable under this Guaranty, (b) the Term B Maturity Date and (c) the latest date of expiration or termination of all Revolving Letters of Credit, such amount shall be received and held in trust for the benefit of the Lender Parties, shall be segregated from other property and funds of such Guarantor and shall forthwith be paid or delivered to the Administrative Agent in the same form as so received (with any necessary endorsement or assignment) to be credited and applied to the Guaranteed Obligations and all other amounts payable under this Guaranty, whether matured or unmatured, in accordance with the terms of the Loan Documents, or to be held as Collateral for any Guaranteed Obligations or other amounts payable under this Guaranty thereafter arising. If (i) any Guarantor shall make payment to any Lender Party of all or any part of the Guaranteed Obligations, (ii) all of the Guaranteed Obligations and all other amounts payable under this Guaranty shall have been paid in full in Cash, (iii) the Term B Maturity Date shall have occurred, and (c) all Revolving Letters of Credit shall have expired or been terminated, the Lender Parties will, at such Guarantor’s request and expense, execute and deliver to such Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to such Guarantor of an interest in the Guaranteed Obligations resulting from such payment made by such Guarantor pursuant to this Guaranty. SECTION 8.05. Subordination. Each Guarantor hereby subordinates any and all debts, liabilities and other obligations owed to such Guarantor by each other Loan Party (the “Subordinated Obligations”) to the Guaranteed Obligations to the extent and in the manner hereinafter set forth in this Section 8.05: (a) Prohibited Payments, Etc. Except during the continuance of any Event of Default, each Guarantor may receive regularly scheduled payments from any other Loan Party on account of the Subordinated Obligations in compliance with the Security Deposit Agreement. After the occurrence and during the continuance of any Event of Default, however, unless the

96 Required Lenders otherwise agree, no Guarantor shall demand, accept or take any action to collect any payment on account of the Subordinated Obligations other than to the extent payment of such Subordinated Obligations is permitted under the terms of the Security Deposit Agreement and the other Loan Documents. (b) Prior Payment of Guaranteed Obligations. In any proceeding under any Bankruptcy Law relating to any other Loan Party, each Guarantor agrees that the Lender Parties shall be entitled to receive payment in full in Cash of all Guaranteed Obligations (including all interest and expenses accruing after the commencement of a proceeding under any Bankruptcy Law, whether or not constituting an allowed claim in such proceeding (“Post-Petition Interest”)) before such Guarantor receives payment of any Subordinated Obligations. (c) Turn-Over. After the occurrence and during the continuance of any Default, each Guarantor shall, if the Administrative Agent so requests, collect, enforce and receive payments on account of the Subordinated Obligations as trustee for the Lender Parties and deliver such payments to the Administrative Agent on account of the Guaranteed Obligations (including all Post-Petition Interest), together with any necessary endorsements or other instruments of transfer, but without reducing or affecting in any manner the liability of such Guarantor under the other provisions of this Guaranty. (d) Administrative Agent Authorization. After the occurrence and during the continuance of any Default, the Administrative Agent is authorized and empowered (but without any obligation to so do), in its discretion, (i) in the name of each Guarantor, to collect and enforce, and to submit claims in respect of, the Subordinated Obligations and to apply any amounts received thereon to the Guaranteed Obligations (including any and all Post-Petition Interest), and (ii) to require each Guarantor (A) to collect and enforce, and to submit claims in respect of, the Subordinated Obligations and (B) to pay any amounts received on such obligations to the Administrative Agent for application to the Guaranteed Obligations (including any and all Post-Petition Interest). SECTION 8.06. Continuing Guaranty; Assignments. This Guaranty is a continuing guaranty and shall (a) remain in full force and effect until a Repayment Event has occurred, (b) be binding upon each Guarantor, its successors and assigns and (c) inure to the benefit of and be enforceable by the Lender Parties and their successors, transferees and assigns. Without limiting the generality of clause (c) of the immediately preceding sentence, any Lender Party may assign or otherwise transfer all or any portion of its rights and obligations under this Agreement (including, without limitation, all or any portion of its Commitments, the Loans owing to it and any Note or Notes held by it) to any other Person, and such other Person shall thereupon become vested with all the benefits in respect thereof granted to such Lender Party herein or otherwise, in each case as and to the extent provided in Section 9.07. No Guarantor shall have the right to assign its rights hereunder or any interest herein without the prior written consent of the Required Lenders, which consent may be granted or withheld in the Required Lenders’ sole and absolute discretion.

(a) The Borrower agrees to pay on demand (i) all costs and expenses of each Agent and Revolving Issuing Bank in connection with the preparation, execution, delivery, administration, modification and amendment of, or any consent or waiver under, the Loan Documents (including, without limitation, (A) all due diligence, collateral review, syndication, transportation, computer, duplication, appraisal, audit, insurance, consultant, search, filing and recording fees and expenses and (B) the reasonable fees and expenses of counsel for each Agent with respect thereto, with respect to advising such Agent or Revolving Issuing Bank, as the case may be, as to its rights and responsibilities, or the perfection, protection or preservation of rights or interests, under the Loan Documents, with respect to negotiations with any Loan Party or with other creditors of any Loan Party or any of its Subsidiaries arising out of any Default or any events or circumstances that may give rise to a Default and with respect to presenting claims in or otherwise participating in or monitoring any bankruptcy, insolvency or other similar proceeding involving creditors’ rights generally and any proceeding ancillary thereto) and (ii) all costs and expenses of each Agent and each Lender Party in connection with the enforcement of the Loan Documents, whether in any action, suit or litigation, or any bankruptcy, insolvency or other similar proceeding affecting creditors’ rights generally (including, without limitation, the reasonable fees and expenses of counsel for the Administrative Agent and each Lender Party with respect thereto). (b) The Borrower agrees to indemnify, defend and save and hold harmless each Agent, each Lender Party and each of their Affiliates and their respective officers, directors, employees, trustees, agents and advisors (each, an “Indemnified Party”) from and against, and shall pay on demand, any and all claims, damages, losses, liabilities and expenses (including, without limitation, reasonable fees and expenses of counsel) that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or by reason of (including, without limitation, in connection with any investigation, litigation or proceeding or preparation of a defense in connection therewith) (i) the Facilities, the actual or proposed use of the proceeds of the Loans or the Revolving Letters of Credit, the Loan Documents or any of the transactions contemplated thereby or (ii) the actual or alleged presence of Hazardous Materials on any property of any Loan Party or any of its Subsidiaries or any Environmental Action relating in any way to any Loan Party or any of its Subsidiaries, except to the extent such claim, damage, loss, liability or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party’s gross negligence or willful misconduct. In the case of an investigation, litigation or other proceeding to which the indemnity in this Section 9.04(b) applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by any Loan Party, its directors, shareholders or creditors, any Indemnified Party or any other Person, whether or not any Indemnified Party is otherwise a party thereto and whether or not the transactions contemplated thereby are consummated. The Borrower also agrees not to assert any claim against any Agent, any Lender Party or any of their Affiliates, or any of their respective officers, directors, employees, trustees, agents and advisors, on any theory of liability, for special, indirect, consequential or punitive damages arising out of or otherwise relating to the Facilities, the actual or proposed use of the proceeds of the Loans or the Revolving Letters of Credit, the Loan Documents or any of the transactions contemplated by the Loan Documents. (c) If any payment of principal of any Loan is made by the Borrower to or for the account of a Lender Party other than on the last day of the Interest Period for such Loan as a

102 result of a payment pursuant to Section 2.06, acceleration of the maturity of the Loans pursuant to Section 6.01 or for any other reason, or if the Borrower fails to make any payment or prepayment of a Loan for which a notice of prepayment has been given or that is otherwise required to be made, whether pursuant to Section 2.04, 2.06 or 6.01 or otherwise, the Borrower shall, upon demand by such Lender Party (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender Party any amounts required to compensate such Lender Party for any additional losses, costs or expenses that it may reasonably incur as a result of such payment or such failure to pay or prepay, as the case may be, including, without limitation, any loss (excluding loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender Party to fund or maintain such Loan. (d) If any Loan Party fails to pay when due any costs, expenses or other amounts payable by it under any Loan Document, including, without limitation, fees and expenses of counsel and indemnities, such amount may be paid on behalf of such Loan Party by the Administrative Agent or any Lender Party, in its sole discretion. (e) Without prejudice to the survival of any other agreement of any Loan Party hereunder or under any other Loan Document, the agreements and obligations of the Borrower contained in Sections 2.10 and 2.12 and this Section 9.04 shall survive the payment in full of principal, interest and all other amounts payable hereunder and under any of the other Loan Documents. SECTION 9.05. Right of Set-off. Upon (a) the occurrence and during the continuance of any Event of Default and (b) the making of the request or the granting of the consent specified by Section 6.01 to authorize the Administrative Agent to declare the Loans due and payable pursuant to the provisions of Section 6.01, each Agent and each Lender Party and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and otherwise apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Agent, such Lender Party or such Affiliate to or for the credit or the account of the Borrower against any and all of the Obligations of the Borrower now or hereafter existing under the Loan Documents, irrespective of whether such Agent or such Lender Party shall have made any demand under this Agreement and although such Obligations may be unmatured. Each Agent and each Lender Party agrees promptly to notify the Borrower after any such set-off and application; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Agent and each Lender Party and their respective Affiliates under this Section are in addition to other rights and remedies (including, without limitation, other rights of set-off) that such Agent, such Lender Party and their respective Affiliates may have. SECTION 9.06. Binding Effect. This Agreement shall become effective when it shall have been executed by the Borrower and each Agent and the Administrative Agent shall have been notified by each initial Lender Party that such initial Lender Party has executed it and thereafter shall be binding upon and inure to the benefit of the Borrower, each Agent and each Lender Party and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of

103 each Lender Party. This Agreement is intended to be solely for the benefit of the parties hereto and is not intended to confer any benefits upon, or create any rights in favor of, any person other than the parties hereto. SECTION 9.07. Assignments and Participations. (a) Each Lender Party may assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment or Commitments, the Loans owing to it, and the Note or Notes held by it); provided, however, that (i) each such assignment shall be of a uniform, and not a varying, percentage of all rights and obligations under and in respect of any or all Facilities, (ii) except in the case of an assignment to a Person that, immediately prior to such assignment, was a Lender Party, an Affiliate of any Lender Party or an Approved Fund of any Lender Party or an assignment of all of a Lender Party’s rights and obligations under this Agreement, the aggregate amount of the Commitments being assigned to such Eligible Assignee pursuant to such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be less than $2,000,000 (or such lesser amount as shall be approved by the Administrative Agent and, so long as no Default shall have occurred and be continuing at the time of effectiveness of such assignment, the Borrower), (iii) each such assignment shall be to an Eligible Assignee, (iv) no such assignments shall be permitted without the written consent of the Administrative Agent, which consent shall not be unreasonably withheld and (v) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, together with any Note or Notes (if any) subject to such assignment. (b) [Reserved]. (c) [Reserved]. (d) Upon such execution, delivery, acceptance and recording, from and after the effective date specified in such Assignment and Acceptance, (i) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a Lender or Revolving Issuing Bank, as the case may be, hereunder and (ii) the Lender or Revolving Issuing Bank assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights (other than its rights under Sections 2.10, 2.12 and 9.04 to the extent any claim thereunder relates to an event arising prior to such assignment) and be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of the remaining portion of an assigning Lender’s or Revolving Issuing Bank’s rights and obligations under this Agreement, such Lender or Revolving Issuing Bank shall cease to be a party hereto). (e) By executing and delivering an Assignment and Acceptance, each Lender Party assignor thereunder and each assignee thereunder confirm to and agree with each other and the other parties thereto and hereto as follows: (i) other than as provided in such Assignment and Acceptance, such assigning Lender Party makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with any Loan Document or the execution, legality, validity, enforceability,

104 genuineness, sufficiency or value of, or the perfection or priority of any lien or security interest created or purported to be created under or in connection with, any Loan Document or any other instrument or document furnished pursuant thereto; (ii) such assigning Lender Party makes no representation or warranty and assumes no responsibility with respect to the financial condition of any Loan Party or the performance or observance by any Loan Party of any of its obligations under any Loan Document or any other instrument or document furnished pursuant thereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in Section 4.01 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon any Agent, such assigning Lender Party or any other Lender Party and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes each Agent to take such action as agent on its behalf and to exercise such powers and discretion under the Loan Documents as are delegated to such Agent by the terms hereof and thereof, together with such powers and discretion as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations that by the terms of this Agreement are required to be performed by it as a Lender or Revolving Issuing Bank, as the case may be. (f) The Administrative Agent, acting for this purpose (but only for this purpose) as the agent of the Borrower, shall maintain at its address referred to in Section 9.02 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the Lender Parties and the Commitment under each Facility of, and principal amount of the Loans owing under each Facility to, each Lender Party from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Agents and the Lender Parties shall treat each Person whose name is recorded in the Register as a Lender Party hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Agent or any Lender Party at any reasonable time and from time to time upon reasonable prior notice. (g) Upon its receipt of an Assignment and Acceptance executed by an assigning Lender Party and an assignee, together with any Note or Notes (if any) subject to such assignment, the Administrative Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of Exhibit C hereto, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrower and each other Agent. In the case of any assignment by a Lender, within five Business Days after its receipt of such notice, the Borrower, at its own expense, shall execute and deliver to the Administrative Agent in exchange for the surrendered Note or Notes (if any) an amended and restated Note (which shall be marked “Amended and Restated”) to the order of such Eligible Assignee in an amount equal to the Commitment assumed by it under each Facility pursuant to such Assignment and Acceptance and, if any assigning Lender that had a Note or Notes prior to such assignment has retained a Commitment hereunder under such Facility, an amended and restated Note to the order of such assigning Lender in an amount equal to the Commitment retained by it hereunder. Such amended and restated Note or Notes shall be

105 dated the effective date of such Assignment and Acceptance and shall otherwise be in substantially the form of Exhibit A-1 or A-2 hereto, as the case may be. (h) Each Lender Party may sell participations to one or more Persons (other than any Loan Party or any of its Affiliates) in or to all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitments, the Loans owing to it and the Note or Notes (if any) held by it); provided, however, that (i) such Lender’s obligations under this Agreement (including, without limitation, its Commitments) shall remain unchanged, (ii) such Lender Party’s shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender Party shall remain the holder of any such Note for all purposes of this Agreement, (iv) the Borrower, the Agents and the other Lender Parties shall continue to deal solely and directly with such Lender Party in connection with such Lender Party’s rights and obligations under this Agreement and (v) no participant under any such participation shall have any right to approve any amendment or waiver of any provision of any Loan Document, or any consent to any departure by any Loan Party therefrom. (i) Any Lender Party may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 9.07, disclose to the assignee or participant or proposed assignee or participant any information relating to the Borrower furnished to such Lender Party by or on behalf of the Borrower; provided, however, that, prior to any such disclosure, the assignee or participant or proposed assignee or participant shall agree to preserve the confidentiality of any Confidential Information received by it from such Lender Party. (j) Notwithstanding any other provision set forth in this Agreement, any Lender Party may at any time create a security interest in all or any portion of its rights under this Agreement (including, without limitation, the Loans owing to it and the Note or Notes (if any) held by it) in favor of any Federal Reserve Bank or Federal Home Loan Bank in accordance with Regulation A of the Board of Governors of the Federal Reserve System or similar laws and regulations relating to the Federal Home Loan Banks. (k) Notwithstanding anything to the contrary contained herein, any Lender that is a Fund may, without the consent of the Borrower or any other Person, create a security interest in all or any portion of the Loans owing to it and any Note or Notes held by it to the trustee for holders of obligations owed, or securities issued, by such Fund as security for such obligations or securities; provided that, unless and until such trustee actually becomes a Lender in compliance with the other provisions of this Section 9.07, (i) no such pledge shall release the pledging Lender from any of its obligations under the Loan Documents and (ii) such trustee shall not be entitled to exercise any of the rights of a Lender under the Loan Documents even though such trustee may have acquired ownership rights with respect to the pledged interest through foreclosure or otherwise. (l) Notwithstanding anything to the contrary contained herein, any Lender Party (a “Granting Lender”) may grant to a special purpose funding vehicle identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower (an “SPC”) the option to provide all or any part of any Loan that such Granting Lender would

106 otherwise be obligated to make pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to fund any Loan and (ii) if an SPC elects not to exercise such option or otherwise fails to make all or any part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof. The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender. Each party hereto hereby agrees that (i) no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Lender Party would be liable, (ii) no SPC shall be entitled to the benefits of Sections 2.10 and 2.12 (or any other increased costs protection provision) and (iii) the Granting Lender shall for all purposes, including, without limitation, the approval of any amendment or waiver of any provision of any Loan Document, remain the Lender Party of record hereunder. In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior Debt of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding under the laws of the United States or any State thereof. Notwithstanding anything to the contrary contained in this Agreement, any SPC may (i) with notice to, but without prior consent of, the Borrower and the Administrative Agent and with the payment of a processing fee of $500, assign all or any portion of its interest in any Loan to the Granting Lender and (ii) disclose on a confidential basis any non-public information relating to its funding of Loans to any rating agency, commercial paper dealer or provider of any surety or guarantee or credit or liquidity enhancement to such SPC. This subsection (l) may not be amended without the prior written consent of each Granting Lender, all or any part of whose Loans are being funded by the SPC at the time of such amendment. SECTION 9.08. Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery by telecopier of an executed counterpart of a signature page to this Agreement shall be effective as delivery of an original executed counterpart of this Agreement. SECTION 9.09. No Liability of the Revolving Issuing Banks. The Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any Revolving Letter of Credit with respect to its use of such Revolving Letter of Credit. Neither any Revolving Issuing Bank nor any of its officers or directors shall be liable or responsible for: (a) the use that may be made of any Revolving Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith; (b) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; (c) payment by such Revolving Issuing Bank against presentation of documents that do not comply with the terms of a Revolving Letter of Credit, including failure of any documents to bear any reference or adequate reference to the Revolving Letter of Credit; or (d) any other circumstances whatsoever in making or failing to make payment under any Revolving Letter of Credit, except that the Borrower shall have a claim against such Revolving Issuing Bank, and such Revolving Issuing Bank shall be liable to the Borrower, to the extent of any direct, but not consequential, damages suffered by the Borrower that the Borrower proves were caused by (i) such Revolving Issuing Bank’s willful misconduct

107 or gross negligence as determined in a final, non-appealable judgment by a court of competent jurisdiction in determining whether documents presented under any Revolving Letter of Credit comply with the terms of the Revolving Letter of Credit or (ii) such Revolving Issuing Bank’s willful failure to make lawful payment under a Revolving Letter of Credit after the presentation to it of a draft and certificates strictly complying with the terms and conditions of the Revolving Letter of Credit. In furtherance and not in limitation of the foregoing, such Revolving Issuing Bank may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary and, in connection therewith, shall adhere to Uniform Customs and Practice for Documentary Credits as in effect as at the time of the Revolving Letter of Credit Issuance Date. SECTION 9.10. Confidentiality. Neither any Agent nor any Lender Party shall disclose any Confidential Information to any Person without the consent of the Borrower, other than (a) to such Agent’s or such Lender Party’s Affiliates and their officers, directors, employees, trustees, agents and advisors and to actual or prospective Eligible Assignees and participants, and then only on a confidential basis, (b) as required by any law, rule or regulation or judicial process, (c) as requested or required by any state, Federal or foreign authority or examiner (including the National Association of Insurance Commissioners or any similar organization or quasi-regulatory authority) regulating such Lender Party, (d) to any rating agency when required by it, provided that, prior to any such disclosure, such rating agency shall undertake to preserve the confidentiality of any Confidential Information relating to the Loan Parties received by it from such Lender Party, (e) in connection with any litigation or proceeding to which such Agent or such Lender Party or any of its Affiliates may be a party or (f) in connection with the exercise of any right or remedy under this Agreement or any other Loan Document. SECTION 9.11. Marshalling; Payments Set Aside. Neither any Agent nor any Lender Party shall be under any obligation to marshal any assets in favor of any Loan Party or any other Person or against or in payment of any or all of the Obligations. To the extent that any Loan Party makes a payment or payments to the Administrative Agent or the Lender Parties (or to Administrative Agent, on behalf of the Lender Parties), or any Agent or Lender Party enforces any security interests or exercise its rights of setoff, and such payment or payments or the proceeds of such enforcement or setoff or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside and/or required to be repaid to a trustee, receiver or any other party under any bankruptcy law, any other state or federal law, common law or any equitable cause, then, to the extent of such recovery, the obligation or part thereof originally intended to be satisfied, and all Liens, rights and remedies therefor or related thereto, shall be revived and continued in full force and effect as if such payment or payments had not been made or such enforcement or setoff had not occurred. SECTION 9.12. Patriot Act Notice. Each Lender Party and each Agent (for itself and not on behalf of any Lender Party) hereby notifies the Loan Parties that pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies each Loan Party, which information includes the name and address of such Loan Party and other information that will allow such Lender Party or such Agent, as applicable, to identify such Loan Party in accordance with the Patriot Act. The Borrower shall, and shall cause each of its Subsidiaries to, provide such information and take such actions as are reasonably requested by

108 any Agent or any Lender Party in order to assist the Agents and the Lender Parties in maintaining compliance with the Patriot Act. SECTION 9.13. Jurisdiction, Etc. (a) Each of the parties hereto hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any New York State court or Federal court of the United States of America sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or any of the other Loan Documents to which it is a party, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York State court or, to the fullest extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Except as provided in Section 9.17, nothing in this Agreement shall affect any right that any party may otherwise have to bring any action or proceeding relating to this Agreement or any of the other Loan Documents in the courts of any jurisdiction. (b) Each of the parties hereto irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any of the other Loan Documents to which it is a party in any New York State or Federal court. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. SECTION 9.14. Governing Law. This Agreement and the Notes shall be governed by, and construed in accordance with, the laws of the State of New York. SECTION 9.15. Waiver of Jury Trial. Each of the Borrower, the Agents and the Lender Parties irrevocably waives all right to trial by jury in any action, proceeding or counterclaim (whether based on contract, tort or otherwise) arising out of or relating to any of the Loan Documents, the Loans, the Revolving Letters of Credit or the actions of any Agent or any Lender Party in the negotiation, administration, performance or enforcement thereof. SECTION 9.16. Limitation on Liability. TO THE EXTENT PERMITTED BY APPLICABLE LAW, AND NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS: (A) NONE OF THE ADMINISTRATIVE AGENT, THE LENDER PARTIES OR ANY INDEMNIFIED PARTY SHALL BE LIABLE TO ANY PARTY FOR ANY INDIRECT, SPECIAL, PUNITIVE OR CONSEQUENTIAL DAMAGES IN CONNECTION WITH THEIR RESPECTIVE ACTIVITIES RELATED TO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS, THE TRANSACTIONS CONTEMPLATED THEREBY, THE TERM B LOAN, THE REVOLVING CREDIT LOANS, THE REVOLVING LETTER OF CREDIT LOANS OR OTHERWISE IN CONNECTION WITH THE FOREGOING; (B) WITHOUT LIMITING THE FOREGOING, NONE OF THE ADMINISTRATIVE AGENT, THE LENDER PARTIES OR ANY INDEMNIFIED PARTY SHALL BE SUBJECT TO ANY EQUITABLE REMEDY OR

109 RELIEF, INCLUDING SPECIFIC PERFORMANCE OR INJUNCTION ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS, OR THE TRANSACTIONS CONTEMPLATED THEREBY; (C) NONE OF THE ADMINISTRATIVE AGENT, THE LENDER PARTIES OR ANY INDEMNIFIED PARTY SHALL HAVE ANY LIABILITY TO THE LOAN PARTIES, FOR DAMAGES OR OTHERWISE, ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS, OR THE TRANSACTIONS CONTEMPLATED THEREBY UNTIL THE EFFECTIVE DATE HAS OCCURRED; AND (D) IN NO EVENT SHALL LENDERS’ LIABILITY TO THE LOAN PARTIES FOR FAILURE TO FUND ANY REVOLVING CREDIT LOAN EXCEED ACTUAL DIRECT DAMAGES INCURRED BY THE LOAN PARTIES OF UP TO $20,000,000 IN THE AGGREGATE.
