The Credits

SECTION 2.01 Commitments. Subject to the terms and conditions set forth herein, each Lender agrees to make Revolving Loans to the Borrowers from time to time during the Availability Period in an aggregate principal amount that will not cause (a) such Lender’s Revolving Credit Exposure to exceed such Lender’s Commitment, or (b) the Availability to be less than the Minimum Availability Amount, subject to the Administrative Agent’s authority to make Protective Advances pursuant to Section 2.05(d). Subject to the foregoing and within the foregoing limits, the Borrowers may borrow, repay (or prepay) and reborrow Revolving Loans, on and after the date hereof through the Availability Period, subject to the terms, provisions and limitations set forth herein.

SECTION 2.02 Loans and Borrowings.

(a) Each Revolving Loan (other than a Swingline Loan or Protective Advance) shall be made as part of a Borrowing consisting of Loans made by the Lenders ratably in accordance with their respective Commitments. The failure of any Lender to make any Revolving Loan required to be made by it shall not relieve any other Lender of its obligations hereunder; provided that the Commitments of the Lenders are several and no Lender shall be responsible for any other Lender’s failure to make Revolving Loans as required.

(b) Subject to Section 2.06, each Borrowing shall be comprised entirely of ABR Loans or Eurodollar Loans as the Borrowers may request in accordance herewith; provided that each Swingline Loan and each Protective Advance shall be an ABR Loan. Each Lender at its option may make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Eurodollar Loan; provided that any exercise of such option shall not affect the obligation of the Borrowers to repay such Loan in accordance with the terms of this Agreement.

(c) At the commencement of each Interest Period for any Eurodollar Borrowing, such Borrowing shall be in a minimum amount of $2,000,000 and an aggregate amount that is an integral multiple of $100,000. At the time that each ABR Borrowing (other than a Swingline Loan or Protective Advance) is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $100,000 and not less than $100,000 (except that the foregoing limitation shall not be applicable to the extent that the proceeds of such Borrowing are requested to be disbursed to the Borrowers’ controlled disbursement account maintained with the Administrative Agent); provided that an ABR Revolving Loan may be in an aggregate amount that is equal to the entire unused balance of the total Commitments or that is required to finance the reimbursement of an LC Disbursement as contemplated by Section 2.04(e) or to finance the reimbursement of a Swingline Loan as contemplated by Section 2.05(g). Borrowings of more than one Type may be outstanding at the same time; provided that there shall not at any time be more than a total of six (6) Eurodollar Borrowings outstanding.

(d) Notwithstanding any other provision of this Agreement, the Borrowers shall not be entitled to request, or to elect to convert or continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date.

SECTION 2.03 Requests for Borrowings. To request a Borrowing, the Borrowers shall notify the Administrative Agent of such request by writing, facsimile or telephone (a) in the case of a Eurodollar Borrowing, not later than 11:00 a.m., New York City time, three (3) Business Days before the date of the proposed Borrowing or (b) in the case of an ABR Borrowing, including an ABR Borrowing to finance the reimbursement of an LC Disbursement as contemplated by Section 2.04(e) or to finance the reimbursement of a Swingline Loan as contemplated by Section 2.05(g), not later than 11:00 a.m., New York City time, on the same Business Day of the proposed Borrowing; provided that notice of Borrowings for Swingline Loans shall be governed by Section 2.05(e). Each such Borrowing Request shall be irrevocable and if given by telephone shall be confirmed (except that no such confirmation will be required, unless requested by the Administrative Agent, to the extent the proceeds of such Borrowing are requested, or deemed to be requested, to be disbursed to Borrowers’ controlled disbursement account maintained with the Administrative Agent, in which event Borrowing and repayment procedures shall be in accordance with the cash management arrangements between the Borrowers and the Administrative Agent and as contemplated by Section 4.4(b) of the Security Agreement) promptly by writing or fax to the Administrative Agent of a written Borrowing Request in a form approved by the Administrative Agent and signed by an authorized signer of the Borrowers as set forth in the Facility Letter. Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.02:

(i) the aggregate amount of the requested Borrowing;

(ii) the date of such Borrowing, which shall be a Business Day;

(iii) whether such Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing;

(iv) in the case of a Eurodollar Borrowing, the initial Interest Period to be applicable thereto, which shall be a period contemplated by the definition of the term “Interest Period”; and

(v) the location and number of the Borrowers’ account to which funds are to be disbursed, which shall comply with the requirements of Section 2.05.

If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing, then the Borrowers shall be deemed to have selected an Interest Period of one (1) month’s duration. Promptly following receipt of a Borrowing Request in accordance with this Section, the Administrative Agent shall advise each applicable Lender of the details thereof and of the amount of such Lender’s Loan to be made as part of the requested Borrowing.

SECTION 2.04 Letters of Credit.

(a) General. Subject to the terms and conditions set forth herein, the Borrowers may request the issuance of Letters of Credit for the account of either Borrower or for the account of any Guarantor, in a form reasonably acceptable to the Administrative Agent and the Issuing Bank, at any time and from time to time during the Availability Period. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrowers to, or entered into by the Borrowers with, the Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control. If the Issuing Bank issues any Letter of Credit for the account of any Guarantor, each Borrower shall be jointly and severally liable to the Issuing Bank with respect to such Letter of Credit as if such Letter of Credit had been issued for the account of one of the Borrowers.

(b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrowers shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the Issuing Bank) to the Issuing Bank and the Administrative Agent (at least three (3) Business Days in advance of the requested date of issuance, amendment, renewal or extension) a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with paragraph (c) of this Section), the amount of such Letter of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If requested by the Issuing Bank, the Borrowers also shall submit a letter of credit application on the Issuing Bank’s standard form in connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit the Borrowers shall be deemed to represent and warrant that), after giving effect to such issuance, amendment, renewal or extension (i) the LC Exposure shall not exceed the LC Sublimit, and (ii) the Availability shall not be less than the Minimum Availability Amount.

(c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date one year after the date of issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension); provided that a Letter of Credit may provide that its expiration date shall be automatically extended (but not beyond the date specified in clause (ii) below) to a date not more than one year after the then outstanding expiration date unless, at least a specified number of days prior to such then existing expiration date, the Issuing Bank shall have given the beneficiary thereof notice, in a form that may be specified in such Letter of Credit, that such expiration date shall not be so extended, and (ii) the date that is five (5) Business Days prior to the Maturity Date.

(d) Participations. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from the Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of the Issuing Bank, such Lender’s Applicable Percentage of each LC Disbursement made by the Issuing Bank and not reimbursed by the Borrowers on the date due as provided in paragraph (e) of this Section, or of any reimbursement payment required to be refunded to the Borrowers for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(e) Reimbursement. If the Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the Borrowers shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 12:00 noon, New York City time, on the date that such LC Disbursement is made, if the Borrowers shall have received notice of such LC Disbursement prior to 10:00 a.m., New York City time, on such date, or, if such notice has not been received by the Borrowers prior to such time on such date, then not later than 12:00 noon, New York City time, on (i) the Business Day that the Borrowers receive such notice, if such notice is received prior to 10:00 a.m., New York City time, on the day of receipt, or (ii) the Business Day immediately following the day that the Borrowers receive such notice, if such notice is not received prior to such time on the date of receipt; provided that, (A) if such LC Disbursement is not less than $100,000, the Borrowers may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.03 that such payment be financed with an ABR Revolving Loan, or (B) the Borrowers may, subject to the conditions to borrowing Swingline Loans set forth in Section 2.05, request in accordance with Section 2.05 that such payment be financed with a Swingline Loan. If the Borrowers fail to make such payment when due, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrowers in respect thereof and such Lender’s Applicable Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Applicable Percentage of the payment then due from the Borrowers, in the same manner as provided in Section 2.05 with respect to Loans made by such Lender (and Section 2.05 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrowers pursuant to this paragraph, the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that Lenders have made payments pursuant to this paragraph to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse the Issuing Bank for any LC Disbursement (other than the funding of ABR Revolving Loans or Swingline Loans as contemplated above) shall not constitute a Loan and shall not relieve the Borrowers of their obligation to reimburse such LC Disbursement.

(f) Obligations Absolute. The Borrowers’ joint and several obligation to reimburse LC Disbursements as provided in paragraph (e) of this Section shall, to the fullest extent permitted under applicable law, be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect (other than under circumstances which constitute gross negligence or willful misconduct on the part of the Issuing Bank as finally determined by a court of competent jurisdiction), (iii) payment of the Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit (other than under circumstances which constitute gross negligence or willful misconduct on the part of the Issuing Bank as finally determined by a court of competent jurisdiction), or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrowers’ obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrowers to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrowers to the extent permitted by applicable law) suffered by the Borrowers that are caused by the Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(g) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrowers by telephone (confirmed by telecopy) of such demand for payment and whether the Issuing Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrowers of their obligation to reimburse the Issuing Bank and the Lenders with respect to any such LC Disbursement.

(h) Interim Interest. If the Issuing Bank shall make any LC Disbursement, then, unless the Borrowers shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrowers reimburse such LC Disbursement, at the rate per annum then applicable to ABR Loans; provided that, if the Borrowers fail to reimburse such LC Disbursement when due pursuant to paragraph (e) of this Section, then Section 2.11(d) shall apply. Interest accrued pursuant to this paragraph shall be for the account of the Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to paragraph (c) of this Section to reimburse the Issuing Bank shall be for the account of such Lender to the extent of such payment.

(i) Replacement of the Issuing Bank. The Issuing Bank may be replaced at any time by written agreement among the Borrowers, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement of the Issuing Bank. At the time any such replacement shall become effective, the Borrowers shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 2.10(b). From and after the effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or to such successor and all previous Issuing Banks, as the context shall require. After the replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit.

(j) Cash Collateralization. If any Event of Default shall occur and be continuing, on the Business Day that the Borrowers receive notice from the Administrative Agent or the Required Lenders (or, if the maturity of the Loans has been accelerated, Revolving Lenders with LC Exposure representing greater than 50% of the total LC Exposure) demanding the deposit of cash collateral pursuant to this paragraph, the Borrowers shall deposit in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Revolving Lenders (the “LC Collateral Account”), an amount in cash equal to 105% of the LC Exposure as of such date plus accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to any Borrower described in clause (h) or (i) of Section 7.01. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the Secured Obligations. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account and the Borrowers hereby grant the Administrative Agent a security interest in the LC Collateral Account. Other than any interest earned on such cash collateral while it is on deposit in the LC Collateral Account, such deposits shall not bear interest (it being understood that cash collateral on deposit in the LC Collateral Account may or may not bear interest, at the option and in the discretion of the Administrative Agent). Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrowers for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Revolving Lenders with LC Exposure representing greater than 50% of the total LC Exposure), be applied to satisfy other Secured Obligations. If the Borrowers are required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the Borrowers within three (3) Business Days after all Defaults in existence at such time have been cured or waived or the LC Exposure for which the cash collateral was posted has been eliminated. If cash collateral is required to satisfy the Borrowers’ obligations with respect to the LC Exposure, any amounts in excess of the amount required to satisfy such obligations shall be returned to the Borrowers within fifteen (15) Business Days after receipt by the Administrative Agent of the Borrowers’ request for a return of such excess amount.

(k) Treatment of Existing Letters of Credit. All Letters of Credit issued and outstanding under (and as defined in) the Existing Credit Agreement as of the Effective Date shall remain outstanding on the Effective Date and shall be continued and deemed to constitute “Letters of Credit” hereunder, and the Administrative Agent and the Lenders shall, on the Effective Date, take such actions, and make such adjustments among themselves, as shall be necessary so that the obligations to purchase risk participations in respect of such Letters of Credit are held hereunder pro rata by the Lenders in accordance with their Applicable Percentages.

SECTION 2.05 Funding of Borrowings.

(a) General. Each Lender shall make each Revolving Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 2:00 p.m., New York City time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders, provided that Swingline Loans shall be made as provided in Section 2.05(c) and Protective Advances shall be made as provided in Section 2.05(d). The Administrative Agent will make such Revolving Loans available to the Borrowers by promptly crediting the amount so received, in like funds, to an account of the Borrowers maintained with the Administrative Agent in New York City and designated by the Borrowers either one Business Day prior to the Effective Date or in the applicable Borrowing Request; provided that ABR Revolving Loans made to finance the reimbursement of (i) an LC Disbursement as provided in Section 2.04(e) shall be remitted by the Administrative Agent to the Issuing Bank and (ii) a Protective Advance shall be retained by the Administrative Agent.

(b) Administrative Agent’s Reliance on Lenders’ Commitments. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed time of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section and may, in reliance upon such assumption, make available to the Borrowers a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrowers severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrowers to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrowers, the interest rate applicable to ABR Loans, but without prejudice to any claim that the Borrowers may have against such Lender. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Revolving Loan included in such Borrowing.

(c) Swingline Loans. Notwithstanding anything to the contrary in this Agreement, subject to the terms and conditions set forth herein, the Swingline Lender may, in its discretion, agree to make advances (each, a “Swingline Loan”) to the Borrowers from time to time during the Availability Period, in an aggregate principal amount at any time outstanding that will not cause (i) the aggregate principal amount of outstanding Swingline Loans to exceed $15,000,000 or (ii) except as otherwise provided in Section 2.05(d), Availability to be less than the Minimum Availability Amount; provided that the Swingline Lender shall not be required to make a Swingline Loan to refinance an outstanding Swingline Loan. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrowers may borrow, prepay and reborrow Swingline Loans. All Swingline Loans shall be ABR Borrowings.

(d) Protective Advances. Notwithstanding anything to the contrary set forth herein, subject to the limitations set forth below, from time to time at any time on or after and during the continuance of an Event of Default or upon any other failure of a condition precedent to the funding of Loans or the issuance of Letters of Credit hereunder, the Administrative Agent is authorized by the Borrowers and the Lenders, in the Administrative Agent’s sole discretion (but shall have absolutely no obligation to), to make Loans to the Borrowers, on behalf of all Lenders, which the Administrative Agent, in its Permitted Discretion, deems necessary or desirable (i) to preserve or protect the Collateral, or any portion thereof, (ii) to enhance the likelihood of, or maximize the amount of, repayment of the Loans and other Obligations, or (iii) to pay any other amount chargeable to or required to be paid by the Borrowers pursuant to the terms of this Agreement, including payments of reimbursable expenses (including costs, fees, and expenses as described in Section 9.03) and other sums payable under the Financing Documents (any of such Loans are herein referred to as “Protective Advances”); provided that, the aggregate amount of Protective Advances outstanding at any time shall not at any time exceed the greater of (A) an amount equal to 5% of the aggregate Commitments of all of the Lenders or (B) $12,500,000; provided further that the aggregate amount of outstanding Protective Advances shall not cause (1) the aggregate Revolving Credit Exposure of all of the Lenders to exceed the aggregate Commitments or (2) the Revolving Credit Exposure of any Lender to exceed such Lender’s Commitment. Protective Advances may be made even if Availability would be less than the Minimum Availability Amount after giving effect to the making of any such Protective Advance (provided that no Protective Advance which causes Availability to be less than the Minimum Availability Amount may remain outstanding for more than 45 consecutive days). The Protective Advances shall be secured by the Liens in favor of the Administrative Agent in and to the Collateral and shall constitute Obligations hereunder. All Protective Advances shall be ABR Borrowings. The Administrative Agent’s authorization to make Protective Advances may be revoked at any time by the Required Lenders. Any such revocation must be in writing and shall become effective prospectively upon the Administrative Agent’s receipt thereof. At any time that there is sufficient Availability and the conditions precedent set forth in Section 4.02 have been satisfied, the Administrative Agent may request the Revolving Lenders to make a Revolving Loan to repay a Protective Advance. At any other time the Administrative Agent may require the Lenders to fund their risk participations described below in this Section 2.05(d). Upon the making of a Protective Advance by the Administrative Agent (whether before or after the occurrence of a Default), each Lender shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from the Administrative Agent without recourse or warranty, an undivided interest and participation in such Protective Advance in proportion to its Applicable Percentage. The Administrative Agent, at any time in its sole and absolute discretion, may require that each Lender fund its participation in the then outstanding principal amount of all Protective Advances by giving each Lender notice thereof. Upon the giving of such notice by the Administrative Agent, each Lender shall comply with its obligations under this paragraph by wire transfer of immediately available funds, in the same manner as provided in Section 2.05(b) with respect to Loans made by such Lender (and Section 2.05 shall apply, mutatis mutandis, to the payment obligations of the Lenders). From and after the date, if any, on which any Lender is required to fund its participation in any Protective Advance purchased hereunder, the Administrative Agent shall promptly distribute to such Lender, such Lender’s Applicable Percentage of all payments of principal and interest and all proceeds of Collateral received by the Administrative Agent in respect of such Protective Advance.

(e) Swingline Loan Request. To request a Swingline Loan, the Borrowers shall notify the Swingline Lender of such request by telephone (confirmed by telecopy), not later than 1:00 p.m., New York City time, on the day of a proposed Swingline Loan. Each such notice shall be irrevocable and shall specify the requested date (which shall be a Business Day) and amount of the requested Swingline Loan. If, in its discretion, the Swingline Lender agrees to make any Swingline Loan requested by the Borrowers, the Swingline Lender shall make such Swingline Loan available to the Borrowers by remitting funds to an account of the Borrowers maintained with the Administrative Agent and designated by the Borrowers at the time of such request (or, in the case of a Swingline Loan made to finance the reimbursement of an LC Disbursement, by remittance to the Issuing Bank) by 2:00 p.m., New York City time, on the requested date of such Swingline Loan.

(f) Lender Participation. On the date a Swingline Loan is made by the Swingline Lender, the Swingline Lender shall be deemed without further action by any party hereto, to have sold to each Lender, and each Lender shall be deemed, without further action by any party hereto, to have purchased from the Swingline Lender, a risk participation to the extent of such Lender’s Applicable Percentage in the Swingline Loan so made, such participation to be funded in accordance with clause (g) of this Section 2.05.

(g) Repayment of Swingline Loans; Funding of Participation. The Borrowers jointly and severally promise to pay to the order of the Swingline Lender for its own account the outstanding principal amount of each Swingline Loan on the earliest of (i) the Maturity Date, (ii) the date which is seven (7) days after the Swingline Loan is made and (iii) the date after a Swingline Loan is made when any other Loan is made pursuant to a formal Borrowing Request under Section 2.03 (the earliest of such date with respect to a Swingline Loan herein, the “Swingline Maturity”). Subject to the other terms and conditions of this Agreement, the Borrowers may repay a Swingline Loan on its Swingline Maturity under clause (ii) above or at any time prior thereto by requesting another Loan in accordance with the terms hereof and with the proceeds of such other Loan payable to the Swingline Lender for its own account. The Administrative Agent, on behalf of the Swingline Lender, shall require that each Lender fund its participation in the then outstanding principal amount of all Swingline Loans on at least a weekly basis by giving each Lender notice thereof by facsimile, telephone or e-mail no later than 11:00 a.m. (New York City time) on the date of such required funding. Additionally, if the Borrowers shall not have repaid a Swingline Loan by 1:00 p.m. (New York City time) on the corresponding Swingline Maturity, the Swingline Lender will notify each Lender of the aggregate principal amount of the Swingline Loan which has not been repaid. Upon the giving of any notice by the Swingline Lender under either of the preceding two sentences, each Lender shall comply with its obligation under this paragraph by wire transfer of immediately available funds, in the same manner as provided in Section 2.05(b) with respect to Loans made by such Lender (and Section 2.05(b) shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Swingline Lender the amounts so received by it from the Lenders. Amounts funded by a Lender under this Section 2.05(g) shall be deemed to constitute ABR Revolving Loans hereunder.

(h) Participation Obligations Absolute; Failure to Fund Participation. The obligations of a Lender to fund its participation in the Swingline Loans and Protective Advances in accordance with the terms hereof shall be absolute, unconditional, and irrevocable and shall be performed strictly in accordance with the terms of the Financing Documents under all circumstances whatsoever, including without limitation, the following circumstances: (i) any lack of validity of any Financing Document; (ii) the existence of any Default; (iii) the existence of any claim, set-off, counterclaim, defenses, or other rights which such Lender, any Credit Party, or any other Person may have; (iv) the occurrence of any event that has or would reasonably be expected to have a Material Adverse Effect; (v) the failure of any condition to a Loan under Article IV to be satisfied; (vi) the fact that after giving effect to the funding of the participation Availability may be less than the Minimum Availability Amount; or (vii) any other circumstance whatsoever, whether or not similar to any of the foregoing. If a Lender fails to fund its participation in a Swingline Loan or Protective Advance as required hereby, such Lender shall remain obligated to pay to the Swingline Lender or the Administrative Agent, as applicable, the amount it failed to fund on demand together with interest thereon in respect of the period commencing on the date such amount should have been funded until the date the amount was actually funded at a rate per annum equal to the Federal Funds Effective Rate for such period and the Administrative Agent shall be entitled to offset against any and all sums to be paid to such Lender hereunder the amount due under this sentence. The Administrative Agent shall notify the Borrowers of any participations in any Swingline Loan acquired pursuant to this paragraph, and thereafter payments in respect of such Swingline Loan shall be made to the Administrative Agent and not to the Swingline Lender. Any amounts received by the Swingline Lender from the Borrowers (or other party on behalf of the Borrowers) in respect of a Swingline Loan after receipt by the Swingline Lender of the proceeds of a sale of participations therein shall be promptly remitted to the Administrative Agent; any such amounts received by the Administrative Agent shall be promptly remitted by the Administrative Agent to the Lenders that shall have made their payments pursuant to this paragraph and to the Swingline Lender, as their interests may appear. Any amounts received by the Administrative Agent in respect of a Protective Advance after receipt by the Administrative Agent of the proceeds of a sale of a participation therein shall be promptly remitted by the Administrative Agent to the Lenders that shall have made their payments pursuant to Section 2.05(d) and this Section 2.05(h). The purchase of participations in a Swingline Loan or Protective Advance pursuant to this paragraph shall not relieve the Borrowers of any default in the payment thereof.

SECTION 2.06 Interest Elections.

(a) Each Borrowing on the Effective Date shall be at the Alternate Base Rate and thereafter shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. The Borrowers may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section. The Borrowers may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. This Section shall not apply to Swingline Borrowings or Protective Advances which may not be converted or continued.

(b) To make an election pursuant to this Section, the Borrowers shall notify the Administrative Agent of such election in writing or by facsimile transmission or by telephone (confirmed in writing or by fax) by the time that a Borrowing Request would be required under Section 2.03 if the Borrowers were requesting a Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in a form approved by the Administrative Agent and signed by the Borrowers.

(c) Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.02;

(i) the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall be specified for each resulting Borrowing);

(ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

(iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

(iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”.

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrowers shall be deemed to have selected an Interest Period of one (1) month’s duration.

(d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each applicable Lender of the details thereof and of such Lender’s portion of each resulting Borrowing.

(e) If the Borrowers fail to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies Borrowers, then, so long as an Event of Default is continuing (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) each Eurodollar Borrowing, unless repaid as provided herein, shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

SECTION 2.07 Termination, Reduction and Increase of Commitments.

(a) Unless previously terminated, the Commitments shall terminate on the Maturity Date.

(b) The Borrowers may at any time terminate the Commitments upon (i) the payment in full of all outstanding Loans, together with accrued and unpaid interest thereon and on any Letters of Credit, (ii) the cancellation and return of all outstanding Letters of Credit (or alternatively, with respect to each such Letter of Credit, the furnishing to the Administrative Agent of a cash deposit (or at the discretion of the Administrative Agent a back up standby letter of credit satisfactory to the Administrative Agent) equal to 105% of the LC Exposure as of such date), (iii) the payment in full of the accrued and unpaid fees, (iv) the payment in full of all reimbursable expenses and other Obligations together with accrued and unpaid interest and (v) the furnishing to the Administrative Agent of a cash deposit (or at the discretion of the Administrative Agent a back up standby letter of credit satisfactory to the Administrative Agent) in connection with any Secured Obligations consisting of Banking Services Obligations or Noticed Swap Obligations, in each case, in such amounts as the Lenders (or Affiliates thereof) providing such Banking Services Obligations or Noticed Swap Obligations, as applicable, may require (as such amount shall be certified to the Administrative Agent in writing from such Lender or Affiliate)(unless such Banking Services Obligations or Noticed Swap Obligations, as applicable, are paid in full in cash and terminated in a manner reasonably satisfactory to such Lender or Affiliate)..

(c) The Borrowers may from time to time reduce the Commitments; provided that (i) each reduction of the Commitments shall be in an amount that is an integral multiple of $1,000,000 and not less than $5,000,000 and (ii) the Borrowers shall not reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.09, Availability would be less than the Minimum Availability Amount.

(d) The Borrowers shall notify the Administrative Agent of any election to terminate or reduce the Commitments under paragraphs (b) or (c) of this Section at least three (3) Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the applicable Lenders of the contents thereof. Each notice delivered by the Borrowers pursuant to this Section shall be irrevocable; provided that a notice of termination of the Commitments delivered by the Borrowers may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrowers (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Commitments shall be permanent. Each reduction of the Commitments shall be made ratably among the Lenders with Commitments in accordance with their respective Commitments.

(e) The Borrowers shall have the right to increase the aggregate Commitments by obtaining additional Commitments, either from one or more of the Lenders or another lending institution provided that (i) any such request for an increase shall be in a minimum amount of $15,000,000, (ii) the Borrowers may make a maximum of three (3) such requests, (iii) the aggregate amount of additional Commitments obtained under this Section 2.07(e) shall not exceed $125,000,000, (iv) the Administrative Agent has approved the identity of any such new Lender, such approval not to be unreasonably withheld or delayed, (v) any such new Lender assumes all of the rights and obligations of a “Lender” hereunder, and (vi) the procedure described in Section 2.07(f) have been satisfied.

(f) Any amendment hereto for such an increase or addition shall be in form and substance satisfactory to the Administrative Agent and shall only require the written signatures of the Administrative Agent, the Borrowers and the Lender(s) being added or increasing their Commitments, subject only to the approval of all Lenders if any such increase would cause the aggregate amount of the Commitment of all of the Lenders to exceed $350,000,000. As a condition precedent to such an increase, the Borrowers shall deliver to the Administrative Agent (i) a certificate of each Credit Party (in sufficient copies for each Lender) signed by an authorized officer of such Credit Party (A) certifying and attaching the resolutions adopted by such Credit Party approving or consenting to such increase, and (B) in the case of the Borrowers, certifying that, before and immediately after giving effect to such increase, (x) the representations and warranties contained in Article III and the other Financing Documents are true and correct in all material respects (except that such materiality qualifier shall not be applicable to any representations and warranties that already are qualified or modified by materiality in the text thereof) on and as of such date , except to the extent that such representations and warranties specifically refer to an earlier date, in which case they are true and correct as of such earlier date, and (y) no Default exists and (ii) such customary opinions, certificates and other documents as the Administrative Agent may reasonably request in connection therewith (but in any event, consistent with those opinions, certificates and other documents delivered on the Effective Date), all of which shall be in form and substance reasonably satisfactory to the Administrative Agent.

(g) Within a reasonable time after the effective date of any increase, the Administrative Agent shall, and is hereby authorized and directed to, revise Schedule 2.01 to reflect such increase and shall distribute such revised Schedule to each of the Lenders and the Borrowers, whereupon such revised Schedule shall replace the old Schedule 2.01 and become part of this Agreement. On the Business Day following any such increase, all outstanding ABR Borrowings shall be reallocated among the Lenders (including any newly added Lenders) in accordance with the Lenders’ respective revised Applicable Percentages. Eurodollar Borrowings shall not be reallocated among the Lenders prior to the expiration of the applicable Interest Period in effect at the time of any such increase.

SECTION 2.08 Repayment of Loans; Evidence of Debt.

(a) The Borrowers hereby jointly, severally and unconditionally promise to pay (i) to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Revolving Loan on the Maturity Date and (ii) to the Administrative Agent the then unpaid principal amount of each Protective Advance on the earlier of the Maturity Date and demand by the Administrative Agent. Swingline Loans shall be repaid as provided in Section 2.05(g).

(b) At all times during a Full Cash Dominion Period, on each Business Day, the Administrative Agent shall apply all funds credited to the Collection Account on such Business Day or the immediately preceding Business Day (at the discretion of the Administrative Agent, whether or not immediately available) as follows: (i) if no Event of Default shall have occurred and be continuing at such time, first to prepay any Protective Advances that may be outstanding, second to prepay pro rata the Revolving Loans (including Swing Line Loans), third to cash collateralize outstanding LC Exposure, but only if and to the extent cash collateralization is required pursuant to Section 2.04(j) or Section 2.18(c), and fourth the balance, if any, to the Borrowers’ general operating account; or (ii) if an Event of Default shall have occurred and be continuing at such time, in accordance with the provisions of Section 2.16(b).

(c) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrowers to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(d) The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrowers to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof.

(e) The entries made in the accounts maintained pursuant to paragraph (c) or (d) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrowers to repay the Loans in accordance with the terms of this Agreement. At the Borrowers’ request, the Administrative Agent shall provide a report of such accounts to the Borrowers and work in good faith to reconcile any discrepancies with the Borrowers.

(f) Prior to the Effective Date to the extent requested by a Lender, the Borrowers shall prepare, execute and deliver to such Lender a Revolving Credit Note in the principal amount of such Lender’s Commitment. Thereafter, the Loans evidenced by such promissory note, if any, and interest thereon shall at all times (including after assignment pursuant to Section 9.04) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns). Prior to the Effective Date to the extent requested by the Swingline Lender, the Borrowers shall prepare, execute and deliver to the Swingline Lender the Swingline Note to evidence the Swingline Loans. Each Lender that holds a promissory note issued pursuant to the Existing Credit Agreement shall deliver the original of such promissory note to the Administrative Agent for cancellation promptly following the Effective Date.

SECTION 2.09 Prepayment of Loans.

(a) Optional Prepayment. The Borrowers shall have the right at any time and from time to time to prepay any Loans in whole or in part, subject to the requirements of this Section and Section 2.14. Each optional prepayment of Loans shall be made ratably among the Loans of the Lenders (except that prepayments of Swingline Loans shall be made solely to the Swingline Lender), and such prepayments shall be made with respect to such Types of Loans as the Borrowers may specify by notice to the Administrative Agent at or before the time of such prepayment as provided in Section 2.09(d) below. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.11.

(b) Mandatory Prepayments. The Borrowers shall be obligated to prepay the Loans as follows:

(i) Overadvances. Except as otherwise expressly provided in Section 2.05(d), if, at any time, Availability shall be less than the Minimum Availability Amount, the Borrowers shall prepay Revolving Loans or Swingline Loans in an aggregate amount necessary to cause Availability to be greater than or equal to the Minimum Availability Amount, and such prepayment shall be applied in accordance with Section 2.09(c). Notwithstanding the foregoing provisions of this paragraph, if at any time the Borrowers are required to make a prepayment under this paragraph the Borrowers would incur breakage costs under Section 2.14 as a result of LIBOR Loans being prepaid other than on the last day of an Interest Period applicable thereto, the Borrowers may cause an amount equal to such required prepayment to be deposited into a cash collateral account with the Administrative Agent as provided in Section 2.14.

(ii) Asset Sales and Casualty Events. Within three (3) Business Days of the receipt by any Credit Party or any Restricted Subsidiary of any Net Proceeds from the sale or other disposition (including those arising from a Casualty Event) of any assets of the Credit Parties or any of their Restricted Subsidiaries (other than dispositions permitted pursuant to Sections 6.03(c)(i),(ii), (ix) or (xii)), the Borrowers shall make a mandatory prepayment of the Loans in an amount equal to 100% of the Net Proceeds received, any prepayment to be applied in accordance with Section 2.09(c), provided that so long as no Full Cash Dominion Period is in effect at the time of the receipt of such Net Proceeds, no prepayment on account of any asset sale or disposition shall be required under this clause (ii).

(iii) Sale of Equity. Within three (3) Business Days of the receipt by any Credit Party or any Restricted Subsidiary of any Net Proceeds of the consummation of the issuance of any Equity Interests of Holdings or any Restricted Subsidiary (other than (A) the issuance of any Equity Interest in connection with any incentive plans available to officers, directors or employees of Holdings or any of its Subsidiaries, (B) the issuance of any Equity Interests by any Subsidiary to Holdings or any other Subsidiary or (C) the issuance of any Equity Interest to sellers in connection with a Permitted Acquisition), the Borrowers shall make a mandatory prepayment of the Loans in an amount equal to 100% of the Net Proceeds received, any prepayment to be applied in accordance with Section 2.09(c), provided that so long as no Full Cash Dominion Period is in effect at the time of the receipt of the proceeds of such issuance, no prepayment on account of the issuance of any such Equity Interests shall be required under this clause (iii).

(iv) Incurrence of Indebtedness. Within three (3) Business Days of the receipt by any Credit Party or any Restricted Subsidiary of any Net Proceeds of the consummation of the issuance of any debt securities or other Indebtedness for borrowed money of Holdings or any Restricted Subsidiary (other than Indebtedness permitted pursuant to clauses 6.01(a) through (h), (l), (m), (n) or (o)), the Borrowers shall make a mandatory prepayment of the Loans in an amount equal to 100% of the Net Proceeds received, any prepayment to be applied in accordance with Section 2.09(c), provided that so long as no Full Cash Dominion Period is in effect at the time of the receipt of the proceeds of such issuance, no prepayment on account of the issuance of any such debt securities or Indebtedness shall be required under this clause (iv).

(c) Application of Mandatory Prepayments. In the event of any mandatory prepayment pursuant to Section 2.09(b), such prepayment shall be accompanied by accrued interest to the extent required by Section 2.11 and shall be applied, (i) first, as a payment of accrued and unpaid interest on any Protective Advances, (ii) second, as a payment of the outstanding principal amount of any Protective Advances, (iii) third, as a pro rata payment of accrued and unpaid interest on Swingline Loans, (iv) fourth, as a pro rata payment of the outstanding principal amount of the Swingline Loans, (v) fifth, as a pro rata payment of accrued and unpaid interest on the Revolving Loans (other than Swingline Loans), (vi) sixth, as a pro rata payment of the outstanding principal amount, of the Revolving Loans (other than Swingline Loans), and (vii) seventh, to the repayment of any other Obligations of the Borrowers to the Administrative Agent and the Lenders which are then due and outstanding.

(d) Notice of Prepayment. The Borrowers shall notify the Administrative Agent by telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 12:00 noon, New York City time three (3) Business Days before the date of prepayment, (ii) in the case of prepayment of an ABR Revolving Borrowing, not later than 12:00 noon, New York City time, one Business Day before the date of prepayment, and (iii) in the case of a prepayment of a Swingline Loan, not later than 1:00 p.m., New York City time, on the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided that, if a notice of prepayment is given under the circumstances in which a conditional notice of termination of the Commitments is permitted as contemplated by Section 2.07, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.07. Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the applicable Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.02 (except that the foregoing shall not be applicable (i) to the extent that the payment is made from the operation of Borrowers’ controlled disbursement account maintained with the Administrative Agent, (ii) to a prepayment in full of the aggregate principal amount of a Borrowing then outstanding or (iii) to the extent necessary to apply fully the required amount of a mandatory prepayment).

SECTION 2.10 Fees.

(a) The Borrowers agree to pay to the Administrative Agent for the account of each Lender a commitment fee (the “Revolving Credit Commitment Fee”), which shall accrue at the Applicable Commitment Rate on the average of the daily amount of the unused Commitment of such Lender during the period from and including the Effective Date to but excluding the date on which such Commitment terminates. Accrued Revolving Credit Commitment Fees shall be payable quarterly in arrears on the first Business Day of January, April, July and October of each year and on the date on which the Commitments terminate, commencing on the first such date to occur after the date hereof. All Revolving Credit Commitment Fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). For purposes of computing Revolving Credit Commitment Fees, a Commitment of a Lender shall be deemed to be used to the extent of the outstanding Revolving Loans, Swingline Loans and LC Exposure of such Lender.

(b) The Borrowers agree to pay to the Administrative Agent for the account of each Lender a participation fee with respect to its participation in Letters of Credit, which shall accrue for each day during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure, at a rate per annum equal to the Applicable Margin with respect to interest on Eurodollar Loans for such day, in each case multiplied by the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure, as well as a fronting fee to the Issuing Bank at a rate of 0.125% per annum on the face amount of each Letter of Credit payable in advance and the Issuing Bank’s standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees accrued through and including the last day of each calendar month shall be payable on the first Business Day of each calendar month following such last day, commencing on the first such date to occur after the Effective Date; provided that all such fees shall be payable on the date on which the Commitments terminate and any such fees accruing after the date on which the Commitments terminate shall be payable on demand. Any other fees payable to the Issuing Bank pursuant to this paragraph shall be payable to the Issuing Bank on demand. All participation and fronting fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(c) The Borrowers agree to pay to the Administrative Agent and each Joint Lead Arranger, for its own account, fees in the amounts and at the times separately agreed upon in writing between the Borrowers and the Administrative Agent or Joint Lead Arranger, as applicable.

(d) All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent (or to the Issuing Bank, in the case of fees payable to it) for distribution, in the case of commitment fees and participation fees, to the Lenders. Absent any error in the calculation thereof, fees paid shall not be refundable under any circumstances.

SECTION 2.11 Interest.

(a) The Loans comprising each ABR Borrowing (including each Swingline Loan) shall bear interest for each day on which any principal of such Loans remains outstanding at the Alternate Base Rate for such day plus the Applicable Margin for such day.

(b) The Loans comprising each Eurodollar Borrowing shall bear interest for each day during each Interest Period applicable thereto at the Adjusted LIBO Rate for such Interest Period plus the Applicable Margin for such day.

(c) Each Protective Advance shall bear interest at the Alternate Base Rate plus the Applicable Margin for Revolving Loans plus 2%.

(d) Notwithstanding the foregoing, (i) during the period when any Event of Default of the type described in Section 7.01(g) or (h) shall have occurred and be continuing, (A) all Loans shall automatically and without notice to the Borrowers bear interest at 2% plus the rate otherwise applicable to such Loans as provided in the preceding paragraphs of this Section and (B) in the case of any other amount outstanding hereunder, such amount shall automatically and without notice to the Borrowers accrue at 2% plus the rate applicable to such fee or other obligation as provided and (ii) if there shall occur and be continuing any Event of Default (other than an Event of Default described in Section 7.01(g) or (h)), following written notice delivered to the Borrowers by the Administrative Agent at the request of the Required Lenders (which notice may be revoked at the option of the Required Lenders notwithstanding any provision of Section 9.02 requiring the consent of “each Lender directly affected thereby” for reductions in interest rates), (A) all Loans shall bear interest at 2% plus the rate otherwise applicable to such Loans as provided in the preceding paragraphs of this Section during the period beginning on the date such Event of Default first occurred and ending on the date such Event of Default is cured or waived and (B) in the case of any other amount outstanding hereunder, such amount shall accrue at 2% plus the rate applicable to such fee or other obligation as provided during the period beginning on the date such Event of Default first occurred and ending on the date such Event of Default is cured or waived.

(e) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan, on the Maturity Date and, upon termination of the Commitments; provided that (i) interest accrued pursuant to paragraph (c) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Eurodollar Loan, accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Eurodollar Loan shall be payable on the effective date of such conversion.

(f) All interest hereunder shall be computed on the basis of a year of 360 days for Eurodollar Loans (and for ABR Loans based on the Adjusted LIBO Rate) and 365/366 days for ABR Loans (including Swingline Loans but excluding ABR Loans based on the Adjusted LIBO Rate), and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

SECTION 2.12 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

(a) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate, for such Interest Period; or

(b) the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrowers and the Lenders by telephone or telecopy, as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrowers and the Lenders that the circumstances giving rise to such notice no longer exist (which notification shall be made promptly after the Administrative Agent obtains knowledge of the cessation of such circumstances), (i) any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective and (ii) if any Borrowing Request or Interest Election Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR Borrowing.

SECTION 2.13 Increased Costs.

(a) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate) or the Issuing Bank; or

(ii) impose on any Lender or the Issuing Bank or the London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender or any Letter of Credit or participation therein (other than with respect to Indemnified Taxes or Other Taxes, which shall be governed by Section 2.15 and Excluded Taxes);

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Eurodollar Loan) or to increase the cost to such Lender or the Issuing Bank of participating in, issuing or maintaining any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender or the Issuing Bank hereunder (whether of principal, interest or otherwise with respect to its Eurodollar Loans or its maintenance of, or participation in, Letters of Credit), then the Borrowers will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered.

(b) If any Lender or the Issuing Bank determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or the Issuing Bank’s capital or on the capital of such Lender’s or the Issuing Bank’s holding company, if any, as a consequence of this Agreement or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the Issuing Bank, to a level below that which such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or the Issuing Bank’s policies and the policies of such Lender’s or the Issuing Bank’s holding company with respect to capital adequacy), then from time to time the Borrowers will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company for any such reduction suffered.

(c) A certificate of a Lender or the Issuing Bank setting forth in reasonable detail the calculation of the amount or amounts necessary to compensate such Lender or the Issuing Bank or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrowers and shall be conclusive absent manifest error. The Borrowers shall pay such Lender or the Issuing Bank, as the case may be, the amount shown as due on any such certificate on demand.

(d) Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation; provided that the Borrowers shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section for any increased costs or reductions incurred more than 270 days prior to the date that such Lender or the Issuing Bank, as the case may be, notifies the Borrowers of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof.

SECTION 2.14 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.09(d) and is revoked in accordance therewith) or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrowers pursuant to Section 2.17, then, in any such event, the Borrowers shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market. A certificate of any Lender setting forth in reasonable detail any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrowers and shall be conclusive absent manifest error. The Borrowers shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof. Notwithstanding the foregoing, the Borrowers shall not be required to make any prepayment of a Eurodollar Borrowing pursuant to Section 2.09(b) until the last day of the Interest Period with respect thereto so long as an amount equal to such prepayment is deposited by the Borrowers into a cash collateral account with the Administrative Agent and applied to such prepayment on the last day of such Interest Period.

SECTION 2.15 Taxes.

(a) Any and all payments by or on account of any obligation of the Borrowers hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrowers shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent, Lender or Issuing Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrowers shall make such deductions and (iii) the Borrowers shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) In addition, the Borrowers shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) The Borrowers shall jointly and severally indemnify the Administrative Agent, each Lender and the Issuing Bank, within ten (10) days after written demand therefor, for (i) the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or the Issuing Bank, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrowers hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority and (ii) any and all losses, claims, damages, liabilities and related expenses arising out of, in connection with or as a result of the failure of the Borrowers to deliver to the Administrative Agent the required receipts or other required documentary evidence with respect to a payment made by the Borrowers for Taxes pursuant to this Section 2.15. A certificate setting forth and explaining in reasonable detail the amount of such payment or liability delivered to the Borrowers by a Lender or the Issuing Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive absent manifest error.

(d) Each Lender and Issuing Bank shall indemnify the Borrowers and the Administrative Agent, within 10 days after written demand therefor, for the full amount of any Taxes described in clause (c) of the definition of “Excluded Taxes” that are imposed on amounts paid to such Lender or Issuing Bank by the Borrowers or the Administrative Agent on or with respect to any payment by or on account of any obligation of any Borrower under any Financing Document and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the applicable Lender or Issuing Bank by the Borrowers or the Administrative Agent shall be conclusive absent manifest error. The Borrowers or the Administrative Agent, as applicable, shall notify the applicable Lender or Issuing Bank of the incurrence or assertion of such liability within a reasonable time after the incurrence or assertion. Each Lender and Issuing Bank hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender or Issuing Bank, as the case may be, under this Agreement or any other Financing Document against any amount due to the Administrative Agent under this Section 2.15(d).

(e) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrowers to a Governmental Authority, the Borrowers shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(f) Any Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which a Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to such Borrower (with a copy to the Administrative Agent), such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate. Any Foreign Lender shall provide the Administrative Agent and the relevant Borrower with two properly completed and executed originals of each of the following, as applicable: (i) Forms W-8ECI (claiming exemption from U.S. withholding tax because the income is effectively connected with a U.S. trade or business), W-8BEN (claiming exemption from, or a reduction of, U.S. withholding tax under an income tax treaty) and/or W-8IMY, or any successor forms, (ii) in the case of a Foreign Lender claiming exemption under Sections 871(h) or 881(c) of the Code, Form W-8BEN (claiming exemption from U.S. withholding tax under the portfolio interest exemption) or any successor form and a certificate in form and substance acceptable to the Administrative Agent that such Foreign Lender is not (1) a “bank” within the meaning of Section 881(c)(3)(A) of the Code, (2) a “10 percent shareholder” of any of the Borrowers within the meaning of Section 881(c)(3)(B) of the Code or (3) a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code or (C) any other applicable document prescribed by the IRS certifying as to the entitlement of such Foreign Lender to such exemption from United States withholding tax or reduced rate with respect to all payments to be made to such Foreign Lender under the Finance Documents. Each U.S. Lender shall provide the Administrative Agent and the Borrowers two properly completed and executed originals of Form W-9 or any successor form. The forms to be delivered pursuant to this Section 2.15(f) shall be provided upon execution and delivery of this Agreement, at the time or times prescribed by applicable law, promptly upon reasonable demand by Administrative Agent or the Borrowers and promptly upon learning that such forms have become obsolete or ineffective.

(g) If the Administrative Agent or a Lender determines, in its sole good faith discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrowers or with respect to which the Borrowers have paid additional amounts pursuant to Section 2.15, it shall pay over such refund to the Borrowers (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrowers under this Section 2.15 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided that the Borrowers, upon the request of the Administrative Agent or such Lender, agree to repay the amount paid over to the Borrowers (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event that the Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. This section shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or other information relating to its taxes which it deems confidential) to the Borrowers or any other Person.

SECTION 2.16 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a) The Borrowers shall make each payment required to be made by the Borrowers hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.13, 2.14 or 2.15, or otherwise) prior to 12:00 noon, New York City time, on the date when due, in immediately available funds, without set-off or counterclaim. All payments made in respect of the Loans shall be made for the account of the Lenders pro rata in accordance with each Lender’s Applicable Percentage. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices at 270 Park Avenue, New York, New York, except payments to be made directly to the Issuing Bank as expressly provided herein and except that payments pursuant to Sections 2.13, 2.14, 2.15 and 9.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension; provided that, in the case of any prepayment of principal of or interest on any Eurodollar Loan, if such next succeeding Business Day would fall in the next calendar month, the date for payment shall instead be the next preceding Business Day. All payments hereunder shall be made in dollars.

(b) Any proceeds of Collateral received by the Administrative Agent (i) not constituting either (A) a specific payment of principal, interest, fees or other sum payable under the Financing Documents (which shall be applied as specified by the Borrowers), (B) a mandatory prepayment (which shall be applied in accordance with Section 2.09) or (C) amounts to be applied from the Collection Account during a Full Cash Dominion Period (which shall be applied in accordance with Section 2.08(b)) or (ii) after an Event of Default has occurred and is continuing and (A) the Administrative Agent so elects, (B) the Required Lenders so direct or (C) the Loans are accelerated pursuant to Section 7.02, such funds shall be applied ratably (based upon the Administrative Agent’s and each Lender’s interest in the aggregate outstanding Secured Obligations described in each of categories first through tenth described below) first, to pay any fees, indemnities, or expense reimbursements including amounts then due to the Administrative Agent and the Issuing Bank from the Borrowers (other than in connection with Banking Services Obligations or Swap Obligations), second, to pay any fees or expense reimbursements then due to the Lenders from the Borrowers (other than in connection with Banking Services Obligations or Swap Obligations), third, to pay interest due in respect of the Protective Advances, fourth, to pay the principal of the Protective Advances, fifth, to pay interest then due and payable on the Loans (other than the Protective Advances) ratably, sixth, to prepay principal on the Loans (other than the Protective Advances) and unreimbursed LC Disbursements ratably, seventh, to pay an amount to the Administrative Agent equal to 105% of the aggregate undrawn face amount of all outstanding Letters of Credit and the aggregate amount of any unpaid LC Disbursements, to be held as cash collateral for such Obligations, but only to the extent required to be cash collateralized at such time pursuant to Section 2.04(j) or Section 2.18(c), eighth, to payment of any amounts owing with respect to Secured Obligations consisting of Banking Services Obligations and Noticed Swap Obligations (based on the amounts then certified by the Lender or Affiliate thereof providing the applicable Banking Services or party to the applicable Swap Agreement to the Administrative Agent to be due and payable to such Lender or Affiliate with respect thereto), ninth, to payment of any amounts owing with respect to Secured Obligations consisting of Swap Obligations (other than Noticed Swap Obligations) (based on the amounts then certified by the Lender or Affiliate thereof party to the applicable Swap Agreement to the Administrative Agent to be due and payable to such Lender or Affiliate with respect thereto), tenth, the payment of any other Secured Obligation due to the Administrative Agent or any Lender by the Borrowers, and eleventh, any excess to be returned to the Borrowers. Notwithstanding anything to the contrary contained in this Agreement, unless so directed by the Borrowers, or unless an Event of Default has occurred and is continuing, neither the Administrative Agent nor any Lender shall apply any payment which it receives to any Eurodollar Loan, except (a) on the expiration date of the Interest Period applicable to any such Eurodollar Loan or (b) in the event, and only to the extent, that there are no outstanding ABR Loans and, in any such event, the Borrowers shall pay the break funding payment required in accordance with Section 2.14. The Administrative Agent and the Lenders shall have the continuing and exclusive right to apply and reverse and reapply any and all such proceeds and payments to any portion of the Secured Obligations.

(c) At the election of the Administrative Agent, all payments of principal, interest, LC Disbursements, fees, premiums, reimbursable expenses (including, without limitation, all reimbursement for fees and expenses pursuant to Section 9.03), and other sums payable under the Financing Documents, may be paid from the proceeds of Borrowings made hereunder as such payments become due hereunder whether made following a request by the Borrowers pursuant to Section 2.03 or a deemed request as provided in this Section or may be deducted from any deposit account of any Borrower maintained with the Administrative Agent (other than an escrow account or other account for segregated funds). Each Borrower hereby irrevocably authorizes (i) the Administrative Agent to make a Borrowing for the purpose of paying each payment of principal, interest and fees as it becomes due hereunder or any other amount due under the Financing Documents and agrees that all such amounts charged shall constitute Loans (including Swingline Loans) and that all such Borrowings shall be deemed to have been requested pursuant to Sections 2.03 or 2.05, as applicable, and (ii) the Administrative Agent to charge any deposit account of any Borrower maintained with the Administrative Agent (other than an escrow account or other account for segregated funds) for each payment of principal, interest and fees as it becomes due hereunder or any other amount due under the Financing Documents.

(d) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Revolving Loans or participations in LC Disbursements or Swingline Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and Swingline Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Revolving Loans and participations in LC Disbursements and Swingline Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Revolving Loans and participations in LC Disbursements and Swingline Loans; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrowers pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Credit Parties or any of their Affiliates (as to which the provisions of this paragraph shall apply). The Borrowers consent to the foregoing and agree, to the extent the Borrowers may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrowers rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrowers in the amount of such participation.

(e) Unless the Administrative Agent shall have received notice from the Borrowers prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the Issuing Bank hereunder that the Borrowers will not make such payment, the Administrative Agent may assume that the Borrowers have made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount due. In such event, if the Borrowers have not in fact made such payment, then each of the Lenders or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(f) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.04(d) or (e), 2.05(b) or 2.16(c), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid; application of any such amounts shall be made in such order as may be determined by the Administrative Agent in its discretion. Until such Lender’s unsatisfied obligations are fully paid, such Lender shall be excluded from any determination of Required Lenders under this Agreement.

SECTION 2.17 Mitigation Obligations; Replacement of Lenders

(a) If any Lender requests compensation under Section 2.13, or if the Borrowers are required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.15, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.13 or 2.15, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrowers hereby agree to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment

(b) If any Lender requests compensation under Section 2.13, or if the Borrowers are required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.15, or if any Lender becomes a Defaulting Lender, or if any Lender fails to approve an amendment or waiver to this Agreement requiring its consent, which amendment or waiver is approved by the Required Lenders, then the Borrowers may, at their sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.04), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrowers, shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Revolving Loans and participations in LC Disbursements and Swingline Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrowers (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.13 or payments required to be made pursuant to Section 2.15, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrowers to require such assignment and delegation cease to apply.

SECTION 2.18 Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

(a) fees shall cease to accrue on the unused portion of the Commitment of such Defaulting Lender pursuant to Section 2.10(a);

(b) the Commitment and Revolving Credit Exposure of such Defaulting Lender shall not be included in determining whether all Lenders or the Required Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 9.02), provided that any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender which affects such Defaulting Lender differently than other affected Lenders shall require the consent of such Defaulting Lender; provided, further, that in no event shall the commitment of a Defaulting Lender be increased or extended beyond the Maturity Date without the consent of such Defaulting Lender;

(c) if at the time a Lender becomes a Defaulting Lender, such Lender has any Swingline Exposure or LC Exposure, then:

(i) all or any part of such Swingline Exposure and LC Exposure shall be reallocated among the non-Defaulting Lenders in accordance with their respective Applicable Percentages but only to the extent (x) the sum of all non-Defaulting Lenders’ Revolving Credit Exposures plus such Defaulting Lender’s Swingline Exposure and LC Exposure does not exceed the total of all non-Defaulting Lenders’ Revolving Commitments and (y) the conditions set forth in Section 4.02 are satisfied at such time; and

(ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrowers shall within one (1) Business Day following notice by the Administrative Agent, without prejudice to any rights or remedies of the Borrowers against such Defaulting Lender, (x) first, prepay such Swingline Exposure and (y) second, cash collateralize such Defaulting Lender’s LC Exposure (after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 2.04(j) for so long as such LC Exposure is outstanding;

(iii) if the Borrowers cash collateralize any portion of such Defaulting Lender’s LC Exposure pursuant to Section 2.18(c)(ii), the Borrowers shall not be required to pay any fees to such Defaulting Lender pursuant to Section 2.10(b) with respect to such Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized;

(iv) if the LC Exposure of the non-Defaulting Lenders is reallocated pursuant to Section 2.18(c), then the fees payable to the Lenders pursuant to Section 2.10(a) and Section 2.10(b) shall be adjusted in accordance with such non-Defaulting Lenders’ Applicable Percentages; or

(v) if any Defaulting Lender’s LC Exposure is neither cash collateralized nor reallocated pursuant to Section 2.18(c), then, without prejudice to any rights or remedies of the Issuing Bank or any Lender hereunder, all letter of credit fees payable under Section 2.10(b) with respect to such Defaulting Lender’s LC Exposure shall be payable to the Issuing Bank until such LC Exposure is cash collateralized and/or reallocated;

(d) The Swingline Lender shall not be required to fund any Swingline Loan and the Issuing Bank shall not be required to issue, amend or increase any Letter of Credit, unless it is satisfied that the related exposure will be 100% covered by the Commitments of the non-Defaulting Lenders and/or cash collateral will be provided by the Borrowers in accordance with Section 2.18(c), and participating interests in any such newly issued or increased Letter of Credit or newly made Swingline Loan shall be allocated among non-Defaulting Lenders in a manner consistent with Section 2.18(c)(i) (and Defaulting Lenders shall not participate therein); and

(e) in the event and on the date that each of the Administrative Agent, the Borrowers, the Issuing Bank and the Swingline Lender agrees that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the Swingline Exposure and LC Exposure of the other Lenders shall be readjusted to reflect the inclusion of such Lender’s Commitment and on such date such Lender shall purchase at par such of the Loans of the other Lenders (other than Swingline Loans) as the Administrative Agent shall determine may be necessary in order for such Lender to hold such Loans in accordance with its Applicable Percentage.

SECTION 2.19 Returned Payments. If after receipt of any payment which is applied to the payment of all or any part of the Obligations, the Administrative Agent or any Lender is for any reason (other than under circumstances which constitute gross negligence or willful misconduct on the part of the Administrative Agent or such Lender as determined by a court of competent jurisdiction) compelled to surrender such payment or proceeds to any Person because such payment or application of proceeds is invalidated, declared fraudulent, set aside, determined to be void or voidable as a preference, impermissible setoff, or a diversion of trust funds, or for any other reason, then the Obligations or part thereof intended to be satisfied shall be revived and continued and this Agreement shall continue in full force as if such payment or proceeds had not been received by the Administrative Agent or such Lender. The provisions of this Section 2.19 shall be and remain effective notwithstanding any contrary action which may have been taken by the Administrative Agent or any Lender in reliance upon such payment or application of proceeds. The provisions of this Section 2.19 shall survive the termination of this Agreement.

ARTICLE III.

Representations and Warranties

The Borrowers represent and warrant to the Lenders and the Administrative Agent that:

SECTION 3.01 Existence and Power. Each Credit Party is a corporation organized, validly existing and in good standing under the laws of the State of Delaware, and has all necessary powers required to carry on its business as now conducted and, except where the failure to do so would not be reasonably expected to result in a Material Adverse Effect, is qualified to do business in, and is in good standing in, every jurisdiction where such qualification is required.

SECTION 3.02 Corporate and Governmental Authorization; No Contravention. The execution, delivery and performance by each Credit Party of the Financing Documents to which it is a party are within its corporate powers, have been duly authorized by all necessary corporate action, require no action by or in respect of, or filing with, any Governmental Authority (except as contemplated by the Security Agreement) and do not contravene, or constitute a default under, any provision of applicable law or regulation or of its charter or bylaws or of any agreement, judgment, injunction, order, decree or other instrument binding upon each (except for any such breach or default which would not reasonably be expected to have a Material Adverse Effect) or result in the creation or imposition of any Lien on any asset of the Credit Parties or any of their Restricted Subsidiaries (except the Liens in favor of the Administrative Agent under the Security Agreement).

SECTION 3.03 Binding Effect. This Agreement and the other Financing Documents to which each Credit Party is a party constitute valid and binding agreements of such Credit Party, in each case enforceable in accordance with their respective terms, except as the enforceability thereof may be limited by bankruptcy, insolvency, reorganization or moratorium or other similar laws relating to the enforcement of creditors’ rights generally and by general equitable principles.

SECTION 3.04 Financial Information.

(a) The Borrowers have heretofore furnished to the Administrative Agent (i) consolidated financial statements of Holdings and its Subsidiaries for the fiscal years ended December 31, 2007 and December 31, 2008, audited by PriceWaterhouseCoopers LLP, independent public accountants, and (ii) management prepared consolidated financial statements of Holdings and its Subsidiaries for the fiscal quarters ended March 31, 2009, June 30, 2009 and September 30, 2009. Such financial statements present fairly in all material respects the financial condition and results of operations of Holdings and its Subsidiaries as of the dates and for the periods indicated in accordance with GAAP consistently applied (except, in the case of quarterly financial statements, for the presentation of footnotes and for applicable normal year-end audit adjustments).

(b) The Borrowers have heretofore furnished to the Administrative Agent monthly for the 2010, 2011 and 2012 fiscal years, projected consolidated income statements, balance sheets and cash flows of Holdings and its Subsidiaries, all in form and substance reasonably satisfactory to the Lenders in their good faith judgment, all such projections disclosing all assumptions made by Holdings and its Subsidiaries in formulating such projections and giving effect to the Transactions. The projections have been prepared on the basis of the assumptions stated therein, and reflect as of the Effective Date the good faith estimate of Holdings and its Subsidiaries of the results of operations and other information projected therein, provided that no representation is made that the assumptions will prove to be correct or that such projections will be realized, it being understood that projections are subject to significant uncertainties.

(c) Since September 30, 2009, no event, change or condition has occurred that has had, or could reasonably be expected to have, a Material Adverse Effect.

SECTION 3.05 Litigation. There is no action, suit or proceeding pending against, or to the knowledge of the Borrowers threatened against or affecting, Holdings or any of its Subsidiaries before any arbitrator or any Governmental Authority, that (a) except for the Disclosed Matters, would reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect, or (b) which would in any material respect draw into question the enforceability against the Credit Parties of any of the Financing Documents, taken as a whole.

SECTION 3.06 Compliance with ERISA. Each of Holdings and its Subsidiaries and each ERISA Affiliate has fulfilled its obligations under the minimum funding standards of ERISA and the Code with respect to each Plan and is in compliance in all material respects with the presently applicable provisions of ERISA and the Code with respect to each Plan, and has not incurred any liability under Title IV of ERISA (i) to the PBGC other than a liability to the PBGC for premiums under Section 4007 of ERISA or (ii) in respect of a Multiemployer Plan which has not been discharged in full when due.

SECTION 3.07 Taxes. Each of Holdings and its Subsidiaries has filed all applicable United States Federal income tax returns and all other material tax returns which are required to be filed by it and has paid all taxes stated to be due in such returns or pursuant to any assessment received by it, except for (a) taxes the amount, applicability or validity of which is being contested in good faith by appropriate proceedings and (b) such returns or taxes which, if not filed or paid, would not constitute a Material Adverse Effect. The charges, accruals and reserves on the books of Holdings and its Subsidiaries in respect of taxes or other similar governmental charges, additions to taxes and any penalties and interest thereon are, in the opinion of the Borrowers, adequate.

SECTION 3.08 Environmental Compliance. Except as described in the Disclosed Matters: (a) Holdings and its Subsidiaries have obtained and are in compliance with all permits, certificates, approvals, licenses and other authorizations (“Permits”) which are required under Environmental Laws and necessary for their operations, except for such failures to obtain or comply with such Permits as would not have a Material Adverse Effect; (b) no notice, citation, summons, complaint, or enforcement action has been issued, and, to the best knowledge of Borrowers, no investigation is pending, concerning any alleged failure of Holdings or any Subsidiary to have a required Permit, any alleged violation of Environmental Law or a Permit by Holdings or any Subsidiary, or any use, generation, treatment, storage, disposal or release of a Hazardous Material by Holdings or any Subsidiary or Predecessor, except for such event or events as would not individually or in the aggregate have a Material Adverse Effect; (c) to the best knowledge of Borrowers, neither Holdings nor any of its Subsidiaries nor its Predecessor has used, generated, transported, stored, disposed, discharged, released or threatened to release any Hazardous Materials on, from or under the Real Property which would result in a violation of or liability under Environmental Law, except for such violations or liabilities as would not, individually or in the aggregate, constitute a Material Adverse Effect or be materially adverse to the interests of the Lenders; (d) to the best knowledge of Borrowers, no condition exists on the Real Property that violates or creates liability under the Environmental Laws which would individually or in the aggregate, constitute a Material Adverse Effect; and (e) there are no Liens under Environmental Laws on the interests of any Credit Party in any Real Property, and no governmental actions have been taken, or to Borrowers’ knowledge are pending, which could subject such property to such Liens. Notwithstanding anything to the contrary herein, no representation or warranty is made by the Borrowers under this Section 3.08 as to any environmental conditions or activities of Predecessor, or any violation or liability resulting therefrom, to the extent that the United States Government has assumed responsibility for such condition, activity, violation or liability.

SECTION 3.09 Properties.

(a) As of the Effective Date, each of Holdings and its Restricted Subsidiaries has good title to, or valid leasehold interests in, all its real and personal property reflected on the balance sheet described in Section 3.04(a) (other than assets which are the subject of a Capital Lease Obligation), except for (i) minor defects in title that do not interfere with its ability to conduct its business as currently conducted or to utilize such properties for their intended purposes and (ii) uranium inventory and other property owned by Customers of the Credit Parties and other third parties for which a corresponding liability in favor of such Customers or third parties is reflected in such balance sheet.

(b) Except to the extent set forth on Schedule 3.09(b), each of Holdings and its Restricted Subsidiaries owns, or is licensed to use, all trademarks, trade names, copyrights, patents and other intellectual property material to its business, and the use thereof by Holdings and its Restricted Subsidiaries does not infringe upon the rights of any other Person, except for any such infringements that, individually or in the aggregate, would not reasonably be expected to result in a Material Adverse Effect.

SECTION 3.10 Compliance with Laws and Agreements. Each of Holdings and its Subsidiaries is in compliance with all laws, regulations and orders of any Governmental Authority applicable to it or its property (except for Environmental Laws which are the subject of Section 3.08), except where the failure to do so, individually or in the aggregate, would not reasonably be expected to result in a Material Adverse Effect. Each of Holdings and its Restricted Subsidiaries is in compliance with all indentures, agreements and other instruments binding upon it or its property, and has all material governmental licenses, authorizations, consents and approvals required to carry on its business as now conducted, except where the failure to do so, individually or in the aggregate, would not reasonably be expected to result in a Material Adverse Effect.

SECTION 3.11 Investment and Holding Company Status. Neither Holdings nor any of its Restricted Subsidiaries is (a) an “investment company” as defined in, or subject to regulation under, the Investment Company Act of 1940 or (b) a “holding company” as defined in, or subject to regulation under, the Public Utility Holding Company Act of 1935.

SECTION 3.12 Full Disclosure. All written information (including electronic communications) furnished at or prior to the Effective Date by the Borrowers to the Administrative Agent or any Lender for purposes of or in connection with this Agreement or any of the Transactions (including information deemed delivered if otherwise in Holdings’ filings with the Securities and Exchange Commission and available on its website) is, taken as whole and in light of the circumstances under which such information is furnished, true and accurate in all material respects on the date as of which such information is furnished, and true and accurate in all material respects on the date as of which such information is stated or certified. It is understood that the foregoing is limited to the extent that (i) projections have been made in good faith by the management of Holdings and its Restricted Subsidiaries and in the view of management of Holdings and its Restricted Subsidiaries are based upon assumptions believed to be reasonable in light of all information known to management as of the Effective Date, and (ii) no representation or warranty is made as to whether the projected results will be realized, it being understood that projections are subject to significant uncertainties.

SECTION 3.13 Security Interest. The Security Agreement creates and grants to the Administrative Agent, for its own benefit and for the benefit of the Lenders, legal, valid and perfected first priority (except as permitted pursuant to Section 6.02 hereof) Liens in the Collateral identified therein. Such Collateral is not subject to any other Liens whatsoever, except Liens permitted by Section 6.02 hereof.

SECTION 3.14 Solvency.

(a) Immediately after the consummation of the Transactions to occur on the Effective Date, (i) the fair value of the assets of the Credit Parties, taken as a whole, at a fair valuation, will exceed their debts and liabilities, subordinated, contingent or otherwise; (ii) the present fair saleable value of the property of the Credit Parties, taken as a whole, will be greater than the amount that will be required to pay the probable liability of their debts and other liabilities, subordinated, contingent or otherwise, as such debts and other liabilities become absolute and matured; (iii) the Credit Parties, taken as a whole, will be able to pay their debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured; and (iv) the Credit Parties, taken as a whole, will not have unreasonably small capital with which to conduct their business in which they are engaged as such business is now conducted and is proposed to be conducted after the Effective Date.

(b) Neither Borrower intends to, or believes that it or any other Credit Party will, incur debts beyond its ability to pay such debts as they mature, taking into account the timing of and amounts of cash to be received by it or any other Credit Party and the timing of the amounts of cash to be payable on or in respect of its Indebtedness or the Indebtedness of any other Credit Party.

(c) Neither Borrower believes that final judgments against Holdings or any Restricted Subsidiary in actions for money damages presently pending will be rendered at a time when, or in an amount such that, they will be unable to satisfy any such judgments promptly in accordance with their terms (taking into account the maximum reasonable amount of such judgments in any such actions and the earliest reasonable time at which such judgments might be rendered). The cash flow of Holdings and its consolidated Restricted Subsidiaries, after taking into account all other anticipated uses of the cash of Holdings and its consolidated Restricted Subsidiaries (including the payments on or in respect of debt referred to in paragraph (b) of this Section), will at all times be sufficient to pay all such judgments promptly in accordance with their terms.

SECTION 3.15 Employee Matters. There are no strikes, slowdowns, work stoppages or controversies pending or, to the knowledge of the Borrowers, threatened between any Credit Party and its employees, other than employee grievances arising in the ordinary course of business, none of which would have, either individually or in the aggregate, a Material Adverse Effect. The hours worked by and payments made to employees of the Credit Parties have not been in violation of the Fair Labor Standards Act, or any other applicable Federal, state, local or foreign law dealing with such matters, except, in each case, as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. All material payments due from any Credit Party, or for which any claim may be made against any Credit Party, on account of wages, vacation pay and employee health and welfare insurance and other benefits, have been paid or accrued as a liability on the books of such Credit Party.

SECTION 3.16 Use of Proceeds. The proceeds of the Loans made and Letters of Credit issued under this Agreement shall be used by the Borrowers for working capital needs, and for general corporate purposes in the ordinary course of business, of the Credit Parties and their Subsidiaries (including Permitted Acquisitions and capital expenditures and ACP Expenditures permitted hereunder), and to refinance certain existing Indebtedness, including, without limitation, under the Existing Credit Agreement.

SECTION 3.17 Subsidiaries. Schedule 3.17 sets forth, as of the Effective Date, all Subsidiaries. The authorized, issued and outstanding Equity Interests in each Subsidiary consists, on the date hereof, of the Equity Interests described on Schedule 3.17.

SECTION 3.18 Insurance. Schedule 3.18 sets forth a description of all insurance maintained by or on behalf of the Credit Parties and their Restricted Subsidiaries as of the Effective Date. As of the Effective Date, all premiums due and payable prior to the Effective Date in respect of such insurance have been paid. The Borrowers believe that the insurance maintained by or on behalf of the Credit Parties and their Restricted Subsidiaries is adequate.

SECTION 3.19 Foreign Assets Control Regulations, etc.. Neither the making of the Loans to, or issuance of Letters of Credit on behalf of, the Borrowers nor the use of the proceeds thereof will violate the Trading with the Enemy Act, as amended, or any of the foreign assets control regulations of the United States Treasury Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling legislation or executive order relating thereto. Without limiting the foregoing, neither the Borrowers nor any of their Subsidiaries or Affiliates (a) is or will become a Person whose property or interests in property are blocked pursuant to Section 1 of Executive Order 13224 of September 23, 2001 Blocking Property and Prohibiting Transactions With Persons Who Commit, Threaten to Commit, or Support Terrorism (66 Fed. Reg. 49079 (2001)) or (b) engages or will engage in any dealings or transactions, or be otherwise associated, with any such Person. The Borrowers and their Subsidiaries and Affiliates are in compliance, in all material respects, with the Uniting And Strengthening America By Providing Appropriate Tools Required To Intercept And Obstruct Terrorism (USA Patriot Act of 2001). No part of the proceeds of the Loans or Letters of Credit will be used, directly or indirectly, in violation in any material respect of the United States Foreign Corrupt Practices Act of 1977, as amended. No Credit Party is engaged in or has engaged in any course of conduct that would reasonably be expected to subject any of their respective properties to any Lien, seizure or other forfeiture under any criminal law, racketeer influenced and corrupt organizations law or other similar laws. None of the Credit Parties or any of their respective Subsidiaries is named on the list of Specially Designated Nationals and Blocked Persons maintained by the United States Department of Treasury Office of Foreign Assets Control.

SECTION 3.20 Material Agreements. All material agreements and contracts to which any Credit Party is a party or is bound as of the date of this Agreement are disclosed in Holdings’ filings with the Securities and Exchange Commission.

SECTION 5.04 Inspection of Property, Books and Records. The Borrowers will keep, and will cause each Restricted Subsidiary to keep, proper books of record and account reflecting their business and activities; and will permit, and will cause each Restricted Subsidiary to permit, upon reasonable notice, representatives of any Lender at such Lender’s expense to visit and inspect any of their respective properties, to examine and make abstracts from any of their respective books and records and to discuss their respective affairs, finances and accounts with their respective officers, senior employees and independent public accountants, all during normal business hours and as often as may reasonably be desired (but not so as to materially interfere with the business of the Borrowers or any of their Restricted Subsidiaries); provided that the Borrowers may, at their option, have one or more employees or representatives present at any such inspection, examination or discussion; provided, further, that each of the foregoing shall be subject to compliance with applicable laws and the Borrowers and their Restricted Subsidiaries shall not be obligated to provide any information that is “classified” for reasons of national security or foreign policy, or otherwise restricted from disclosure under applicable laws or agreements. At the Borrowers’ expense, the Administrative Agent (a) shall have the right to audit, up to two times each fiscal year (provided that (x) if a Default or Event of Default shall have occurred and be continuing, the Administrative Agent shall have the right to conduct audits as often as the Administrative Agent may request in the exercise of its Permitted Discretion and (y) if Availability shall fall below an amount equal to the greater of (1) 20% of the aggregate Commitments of all of the Lenders or (2) $60,000,000, then, during the period from the date that Availability fell below such amount and continuing until the ninetieth (90^th) consecutive day on which Availability exceeds the greater of (1) 20% of the aggregate Commitments of all of the Lenders or (2) $60,000,000, the Administrative Agent shall have the right to conduct audits as often as the Administrative Agent may request in the exercise of its Permitted Discretion), the existence and condition of the Collateral and to review compliance with the Financing Documents, (b) shall have the right to retain an inventory appraiser to appraise the inventory Collateral once each fiscal year (provided that, if a Default or Event of Default shall have occurred and be continuing, the Administrative Agent shall have the right to retain appraisers to appraise the inventory Collateral as often as the Administrative Agent may request in the exercise of its Permitted Discretion) and (c) shall have the right to obtain independent reports regarding the uranium markets, including, spot market value information.

SECTION 5.06 Environmental Matters. The Borrowers will keep and maintain, and will cause their Subsidiaries to keep and maintain, all Real Property and each portion thereof in compliance in all material respects with all applicable Environmental Laws and, except for the Disclosed Matters, promptly notify the Administrative Agent in writing (attaching a copy of any pertinent written material) of (a) any and all material compliance enforcement, cleanup, removal or other governmental or regulatory actions instituted, completed or threatened in writing against the Borrowers or their Subsidiaries by a Governmental Authority pursuant to any applicable Environmental Laws; (b) any and all material claims made or threatened in writing by any Person against Borrowers relating to damage, contribution, cost recovery, compensation, loss or injury resulting from any Hazardous Materials; (c) discovery by any senior officer (vice president or above) of a Borrower or any Subsidiary of any material occurrence or condition on any Real Property or real property adjoining or in the vicinity of such Real Property that would reasonably be expected to cause the interests of any Credit Party in such Real Property or any part thereof to be subject to any restrictions on the ownership, occupancy, transferability or use of such Real Property by any Credit Party or create material liability on the part of any Credit Party under any applicable Environmental Laws; (d) any proceeding for the suspension or termination of a Permit required under Environmental Laws for the operation of the business of the Credit Parties; or (e) any part of the interests of any Credit Party in any Real Property that is or will be subject to a lien imposed under Environmental Law.

SECTION 5.08 Security Interests.

(a) if at any time during the Fixed Charge Applicable Period the Borrowers are required to provide monthly financial statements to the Lenders pursuant to Section 5.01(c), the Fixed Charge Coverage Ratio shall be calculated at the end of each calendar month for the period of twelve consecutive months then most recently ended; and

(b) a breach of the Fixed Charge Coverage Ratio when so tested during a Fixed Charge Applicable Period shall not be cured by a subsequent increase of Availability above the applicable limit set forth above.

SECTION 6.11 ACP Expenditures. Notwithstanding anything to the contrary set forth in this Agreement, the Borrowers shall not permit the aggregate amount of all ACP Expenditures (other than ACP Expenditures made with ACP Specified Grant Proceeds) made by the Credit Parties and their Restricted Subsidiaries from and after the Effective Date to exceed the sum of (1) an amount equal to (x) the ACP Expenditures Base Amount minus (y) the aggregate amount of Investments made in reliance on Section 6.04(q) plus (2) the ACP Net Equity Financing Proceeds (the “Aggregate ACP Expenditures Amount”), provided that the amount of ACP Expenditures attributable to Guarantees under clause (a) of the definition of “ACP Expenditures” at any time shall be limited to the maximum liability at such time of any Borrower or Restricted Subsidiary acting as guarantor thereunder for the payment of guaranteed obligations and, if and as such liability is reduced or increased with the passage of time or otherwise, the portion of ACP Expenditures attributable to such Guarantee shall be reduced or increased, as applicable, in a corresponding amount, it being understood that once such liability is eliminated, the Guarantee will no longer count against any applicable limit on ACP Expenditures hereunder, provided further that

(a) if Availability shall fall below (or, after giving pro forma effect to any ACP Expenditure and the financing thereof, would fall below) an amount equal $75,000,000 (an “ACP Expenditure Reduction Event”):

(i) the aggregate amount of all ACP Expenditures (other than ACP Expenditures made with ACP Specified Grant Proceeds) made during all ACP Expenditure Reduction Periods over the term of this Agreement shall not exceed the lesser of (A) the Aggregate ACP Expenditures Amount less all ACP Expenditures made prior to the date of the proposed ACP Expenditure and (B) $25,000,000; and

(ii) (A) the aggregate amount of ACP Expenditures (other than ACP Expenditures made with ACP Specified Grant Proceeds) that may be made in any calendar month during an ACP Expenditure Reduction Period shall not exceed the lesser of (x) $5,000,000 and (y) the aggregate amount of ACP Expenditures permitted under clause (a)(i) above and (B) the Borrowers shall provide a written certification to the Administrative Agent and the Lenders of the use and purpose of such ACP Expenditure in reasonable detail during such ACP Expenditure Reduction Period; and

(b) no such ACP Expenditures (other than ACP Expenditures made with ACP Specified Grant Proceeds) shall be permitted if an Event of Default has occurred and is continuing or would result therefrom.

For the avoidance of doubt, the parties hereto acknowledge and agree that nothing in this Section 6.11 or in any other provision of any Financing Document shall restrict the ability of the Credit Parties and their Restricted Subsidiaries to transfer, contribute, spend, invest or otherwise dispose of ACP Specified Grant Proceeds for activities related to the American Centrifuge Project.

SECTION 7.03 Performance by the Administrative Agent. If, upon the occurrence and during the continuance of any Event of Default and upon not less than seven (7) days prior written notice by the Administrative Agent to the Borrowers, any Credit Party shall fail to perform any covenant or agreement in accordance with the terms of the Financing Documents, the Administrative Agent may, at the direction of Required Lenders, perform or attempt to perform such covenant or agreement on behalf of the applicable Credit Party. In such event, the Borrowers shall, at the request of the Administrative Agent, promptly pay any amount expended by the Administrative Agent or the Lenders in connection with such performance or attempted performance to the Administrative Agent, together with interest thereon at the applicable default rate from and including the date of such expenditure to but excluding the date such expenditure is paid in full. Notwithstanding the foregoing, it is expressly agreed that neither the Administrative Agent nor any Lender shall have any liability or responsibility for the performance of any obligation of any Credit Party under any Financing Document. The Administrative Agent may be obligated to pay certain amounts to the financial institutions party to the cash management and control agreements executed pursuant hereto from time to time, including without limitations, fees owed to such financial institutions arising from their lock box and other deposit account services and amounts sufficient to reimburse such financial institutions for the amount of any item deposited in the related account which is returned unpaid. In the event either the Administrative Agent is required to pay any such amounts, the Administrative Agent shall notify the Borrowers and Borrowers shall promptly pay any amount so expended by the Administrative Agent to the Administrative Agent together with interest at the applicable default rate from and including the date of such expenditure to but excluding the date that such expenditure is paid in full. Amounts due and unpaid under this Section 7.03 may be funded as Swingline Loans or Revolving Loans subject to the applicable terms and conditions of this Agreement.

Each of the Lenders and the Issuing Bank hereby irrevocably appoints the Administrative Agent as its agent both as administrative agent and collateral agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof and the other Financing Documents, together with such actions and powers as are reasonably incidental thereto.

The bank serving as the Administrative Agent hereunder and under the other Financing Documents shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrowers or their Subsidiaries or other Affiliates thereof as if it were not the Administrative Agent hereunder.

The Administrative Agent shall not have any duties or obligations except those expressly set forth herein or in the other Financing Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or thereby that the Administrative Agent is required to exercise in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02), and (c) except as expressly set forth herein, the Administrative Agent shall not have any duty to disclose, and shall not be liable for any failure to disclose, any information relating to the Borrowers or any of their Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02) or in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Borrowers or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement, (ii) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument or document, (v) the creation, perfection or priority of Liens on the Collateral or the existence of the Collateral or (vi) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrowers), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

The Administrative Agent may perform any and all of its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

With respect to the release of Collateral, the Lenders hereby irrevocably authorize the Administrative Agent, at its option and in its discretion, to release any Lien granted to or held by the Administrative Agent upon any property covered by this Agreement or the other Financing Documents (i) upon termination or expiration of the Commitments, the payment and satisfaction of all obligations arising with respect to the Loans, all fees and expenses, the expiration or termination of all the Letters of Credit and the reimbursement of all LC Disbursements; or (ii) constituting property being sold or disposed of in compliance with the provisions of the Financing Documents (and the Administrative Agent may rely in good faith conclusively on any certificate stating that the property is being sold or disposed of in compliance with the provisions of the Financing Documents, without further inquiry); provided, however, that (x) the Administrative Agent shall not be required to execute any release on terms which, in the Administrative Agent’s opinion, would expose the Administrative Agent to liability or create any obligation or entail any consequence other than the release of such Liens without recourse or warranty, and (y) such release shall not in any manner discharge, affect or impair any Liens upon all interests retained, all of which shall continue to constitute part of the property covered by the Financing Documents.

With respect to perfecting security interests in Collateral which, in accordance with Article 9 of the Uniform Commercial Code or any comparable provision of any Lien perfection statute in any applicable jurisdiction, can be perfected only by possession, each Lender hereby appoints each other Lender its agent for the purpose of perfecting such interest. Should any Lender (other than the Administrative Agent) obtain possession of any such Collateral, such Lender shall notify the Administrative Agent, and, promptly upon the Administrative Agent’s request, shall deliver such Collateral to the Administrative Agent or in accordance with the Administrative Agent’s instructions. Each Lender agrees that it will not have any right individually to enforce or seek to enforce this Agreement or any other Financing Document or to realize upon any Collateral for the Loans, it being understood and agreed that such rights and remedies may be exercised only by or with the approval of the Administrative Agent.

In the event that a petition seeking relief under Title 11 of the United States Code or any other Federal, state or foreign bankruptcy, insolvency, liquidation or similar law is filed by or against any Credit Party or any other Person obligated under the Financing Document, the Administrative Agent is authorized, to the fullest extent permitted by applicable law, to file a proof of claim on behalf of itself and the Lenders in such proceeding for the total amount of obligations owed by such Person. With respect to any such proof of claim which the Administrative Agent may file, each Lender acknowledges that without reliance on such proof of claim, such Lender shall make its own evaluation as to whether an individual proof of claim must be filed in respect of such obligations owed to such Lender and, if so, take the steps necessary to prepare and timely file such individual claim.

Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any time by notifying the Lenders, the Issuing Bank and the Borrowers. Upon any such resignation, the Required Lenders shall have the right, in consultation with the Borrowers, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent which shall be a commercial bank, or an Affiliate of any such commercial bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrowers to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrowers and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article, Section 2.15(d) and Section 9.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any related agreement or any document furnished hereunder or thereunder. Each Lender acknowledges the potential conflict of interest of each other Lender as a result of Lenders holding disproportionate interests in the Loans, and expressly consents to and waives any claim based upon such conflict of interest.

Each Lender and Issuing Bank hereby agrees that (a) it has requested a copy of each Report prepared by or on behalf of the Administrative Agent; (b) the Administrative Agent (i) makes no representation or warranty, express or implied, as to the completeness or accuracy of any Report or any of the information contained therein or any inaccuracy or omission contained in or relating to a Report and (ii) shall not be liable for any information contained in any Report; (c) the Reports are not comprehensive audits or examinations, and that any Person performing any field examination will inspect only specific information regarding the Credit Parties and will rely significantly upon the Credit Parties’ books and records, as well as on representations of the Credit Parties’ personnel and that the Administrative Agent undertakes no obligation to update, correct or supplement the Reports; (d) it will keep all Reports confidential and strictly for its internal use, and it will not share the Report with any Credit Party or any other Person except as otherwise permitted pursuant to this Agreement; and (e) without limiting the generality of any other indemnification provision contained in this Agreement, it will pay and protect, and indemnify, defend, and hold the Administrative Agent and any such other Person preparing a Report harmless from and against, the claims, actions, proceedings, damages, costs, expenses, and other amounts (including reasonable attorney fees) incurred by as the direct or indirect result of any third parties who might obtain all or part of any Report through the indemnifying Lender.

The parties hereto agree that the titles Joint Book Manager, Joint Lead Arranger, Syndication Agent and Documentation Agent are honorary and confer no duties upon such agents except as a Lender hereunder, provided that the Joint Book Managers, Joint Lead Arrangers, Syndication Agent and Documentation Agent shall be entitled to the rights and benefits specifically provided for herein.

SECTION 9.02 Waivers; Amendments.

(a) No failure or delay by the Administrative Agent, the Issuing Bank or any Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the Issuing Bank and the Lenders hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of any Financing Document or consent to any departure by the Borrowers there from shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any Lender or the Issuing Bank may have had notice or knowledge of such Default at the time.

(b) Neither this Agreement nor any other Financing Document nor any provision hereof or thereof may be waived, amended or modified except (i) in the case of this Agreement, pursuant to an agreement or agreements in writing entered into by the Borrowers and the Required Lenders or by the Borrowers and the Administrative Agent with the consent of the Required Lenders or (ii) in the case of any other Financing Document, except as otherwise expressly provided therein, pursuant to an agreement or agreements in writing entered into by the Administrative Agent and the Credit Party or Credit Parties that are party thereto, with the consent of the Required Lenders; provided that no such agreement pursuant to clause (i) and/or clause (ii) above shall (A) increase the Commitment of any Lender without the written consent of such Lender or increase the aggregate amount of the Commitments (except as otherwise permitted under Section 2.07) without the consent of each Lender, (B) reduce the principal amount of any Loan, Note or LC Disbursement or reduce the rate of interest thereon (other than the determination not to charge an increased rate of interest after an Event of Default) (it being agreed that changes to Availability Percentage or any component definitions thereof shall not constitute a reduction in the rate of interest), or reduce any fees payable hereunder, without the written consent of each Lender directly affected thereby, (C) postpone the Maturity Date or the scheduled date of payment of the principal amount of any Loan (other than pursuant to Section 2.09(b) hereof) or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender directly affected thereby, (D) change Sections 2.16(b) or 2.16(d) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender directly affected thereby, (E) increase the advance rates set forth in the definition of Borrowing Base (except that this provision will not restrict the authority of the Administrative Agent to impose or remove reserves on the Borrowing Base), or add new categories of eligible assets to, or broaden the criteria for inclusion of eligible assets in, the Borrowing Base, in each case, in a manner that would have the effect of increasing the Borrowing Base or Availability by more than a de minimis amount, without the written consent of each Lender, (F) increase the maximum permitted LC Exposure, increase the maximum amount of Protective Advances that may be outstanding at any time, release all or a material portion of the Collateral (other than any ACP Property in accordance with the terms hereof), release any Guarantor constituting a Material Subsidiary (or any Collateral consisting of Equity Interests in any Guarantor which is a Material Subsidiary), subordinate the Liens of the Administrative Agent, or with respect to any other Indebtedness of the Borrowers cause the Liens of the Administrative Agent to be pari passu with the Liens securing such other Indebtedness, in each case, with respect to all or substantially all of the Collateral (other than the Indebtedness permitted to be incurred pursuant to Section 2.07 or other Indebtedness that is permitted to be outstanding pursuant to Section 6.01), or subordinate the repayment of all or any substantial part of the Obligations to the repayment of any other Indebtedness, without the written consent of each Lender or (G) change any of the provisions of this Section or the definition of “Required Lenders” or “Protective Advances” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender; provided, further, that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, the Swingline Lender or the Issuing Bank hereunder without the prior written consent of the Administrative Agent, the Swingline Lender or the Issuing Bank, as the case may be.

(c) If, in connection with any proposed amendment, waiver or consent requiring the consent of “each Lender” or “each Lender directly affected thereby,” the consent of the Required Lenders is obtained, but the consent of other necessary Lenders is not obtained (any such Lender whose consent is necessary but not obtained being referred to herein as a “Non-Consenting Lender”), then the Borrowers may elect to replace a Non-Consenting Lender as a Lender party to this Agreement within one hundred fifty (150) days thereafter, provided that, concurrently with such replacement, (i) another bank or other entity which is reasonably satisfactory to the Borrowers and the Administrative Agent shall agree, as of such date, to purchase for cash the Loans and other Obligations due to the Non-Consenting Lender pursuant to an Assignment and Assumption and to become a Lender for all purposes under this Agreement and to assume all obligations of the Non-Consenting Lender to be terminated as of such date and to comply with the requirements of clause (b) of Section 9.04, and (ii) the Borrowers shall pay to such Non-Consenting Lender in same day funds on the day of such replacement (1) all interest, fees and other amounts then accrued but unpaid to such Non-Consenting Lender by the Borrowers hereunder to and including the date of termination, including without limitation payments due to such Non-Consenting Lender under Sections 2.13 and 2.15, and (2) an amount, if any, equal to the payment which would have been due to such Lender on the day of such replacement under Section 2.14 had the Loans of such Non-Consenting Lender been prepaid on such date rather than sold to the replacement Lender.

SECTION 9.03 Expenses; Indemnity; Damage Waiver.

(a) The Borrowers shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and the Syndication Agent and their respective Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent and the Syndication Agent, in connection with the syndication and distribution (including without limitation, via the internet or through a service such as Intralinks) of the credit facilities provided for herein and the preparation and negotiation of the Financing Documents (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the administration of the Financing Documents or any amendments, modifications or waivers of the provisions of the Financing Documents (whether or not the transactions contemplated hereby or thereby shall be consummated), (iii) all reasonable out-of-pocket expenses incurred by the Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder and (iv) during the continuance of a Default, all out-of-pocket expenses incurred by the Administrative Agent, the Issuing Bank or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent, the Issuing Bank or any Lender, in connection with the enforcement, collection or protection of its rights in connection with the Financing Documents, including its rights under this Section, or in connection with the Loans made or Letters of Credit issued hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit. Expenses being reimbursed by the Borrowers under this Section include, subject to the limitations set forth in this Agreement, without limiting the generality of the foregoing, reasonable costs and expenses incurred in connection with:

(i) appraisals and insurance reviews;

(ii) field examinations and the preparation of Reports based on the fees charged by a third party retained by the Administrative Agent or the internally allocated fees for each Person employed by the Administrative Agent with respect to each field examination; provided that that up to two field examinations will be conducted each year unless (x) a Default or Event of Default shall have occurred and be continuing (in which case there shall be no limitation on the number or frequency of field examinations) or (y) Availability shall fall below an amount equal to the greater of (1) 20% of the aggregate Commitments of all of the Lenders or (2) $60,000,000 (in which case, during the period from the date that Availability fell below such amount and continuing until the ninetieth (90^th) consecutive day on which Availability exceeds the greater of (1) 20% of the aggregate Commitments of all of the Lenders or (2) $60,000,000, there shall be no limitation on the number or frequency of field examinations);

(iii) background checks regarding senior management and/or key investors, as deemed necessary or appropriate in the Permitted Discretion of the Administrative Agent;

(iv) taxes, fees and other charges (other than Excluded Taxes) for (A) lien and title searches and title insurance and (B) recording mortgages, filing financing statements and continuations, and other actions reasonably necessary to perfect, protect, and continue the Administrative Agent’s Liens;

(v) sums paid or incurred to take any action required of any Credit Party under the Financing Documents that such Credit Party fails to pay or take; and

(vi) forwarding loan proceeds, collecting checks and other items of payment, and establishing and maintaining the accounts and lock boxes, and costs and expenses of preserving and protecting the Collateral.

All of the foregoing costs and expenses may be charged to the Borrowers as Revolving Loans or to another deposit account, all as described in Section 2.16(c).

(b) The Borrowers shall jointly and severally indemnify the Administrative Agent the Joint Lead Arrangers, the Issuing Bank and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the reasonable fees, charges and disbursements of any counsel for any Indemnitee (other than Indemnified Taxes and Other Taxes for which indemnification shall be made pursuant to Section 2.15 and Excluded Taxes), incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or Letter of Credit or the use of the proceeds there from (including any refusal by the Issuing Bank to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Borrowers or any of their Subsidiaries, or any Environmental Liability related in any way to the Borrowers or any of their Subsidiaries or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claim, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee.

(c) To the extent that the Borrowers fail to pay any amount required to be paid by it to the Administrative Agent, the Issuing Bank or the Swingline Lender under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Administrative Agent, the Issuing Bank or the Swingline Lender, as the case may be, such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent, the Issuing Bank or the Swingline Lender in its capacity as such.

(d) To the extent permitted by applicable law, the Borrowers shall not assert, and hereby waive, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof.

(e) All amounts due under this Section shall be payable promptly after written demand therefor and may be funded as Swingline Loans or Revolving Loans in accordance with the applicable terms and conditions of this Agreement.

SECTION 9.04 Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), except that (i) the Borrowers may not assign or otherwise transfer any of their rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrowers without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including an Affiliate of the Issuing Bank that issues any Letter of Credit) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld or delayed) of the Administrative Agent, the Issuing Bank and the Borrowers, provided that no consent of the Borrowers shall be required (x) for an assignment to an assignee that is a Lender, an Affiliate of a Lender or an Approved Fund immediately prior to giving effect to such assignment or (y) if an Event of Default has occurred and is continuing .

(ii) Assignments shall be subject to the following additional conditions:

(A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund, or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $10,000,000 unless the Borrowers and the Administrative Agent otherwise consent;

(B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement;

(C) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; and

(D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.13, 2.14, 2.15 and 9.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 9.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section.

(iv) The Administrative Agent, acting for this purpose as an agent of the Borrowers, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrowers, the Administrative Agent, the Issuing Bank and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrowers, the Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section, any Note or Notes subject to such assignment and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register, provided that if either the assigning Lender or the assignee shall have failed to make any payment required to be made by it pursuant to Section 2.04(d) or (e), 2.05, 2.15(d), 2.16(d) or 9.03(c), the Administrative Agent shall have no obligation to accept such Assignment and Assumption and record the information therein in the Register unless and until such payment shall have been made in full, together with all accrued interest thereon. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph. Upon notice to the Borrowers, to the extent requested by assignee and, if applicable, the assigning Lender, at the Borrowers’ expense, the Borrowers shall execute and deliver to the Administrative Agent in exchange for such surrendered Notes, new Notes to the order of the assignee in an amount equal to the portion of the Commitments assumed by it pursuant to such Assignment and Assumption and, if the assigning Lender has retained any Commitment hereunder, new Notes to the order of the assigning Lender in an amount equal to the Commitment retained by it hereunder.

(c) (i) Any Lender may, without the consent of the Borrowers, the Administrative Agent or the Issuing Bank, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitments and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrowers, the Administrative Agent, the Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 9.02(b) that affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrowers agree, to the fullest extent permitted under applicable law, that each Participant shall be entitled to the benefits of Sections 2.13, 2.14 and 2.15 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.16(d) as though it were a Lender.

(ii) A Participant shall not be entitled to receive any greater payment under Section 2.13 or 2.15 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant shall not be entitled to the benefits of Section 2.15 unless the Borrowers are notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrowers, to comply with Section 2.15(f) as though it were a Lender.

(d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement and the Notes issued to such Lender to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

SECTION 9.05 Survival. All covenants, agreements, representations and warranties made by the Borrowers herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and the issuance of any Letters of Credit regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Sections 2.13, 2.14, 2.15, 9.03 and 9.12 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or any provision hereof.

SECTION 9.06 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement, the other Financing Documents and any separate letter agreements with respect to fees payable to the Administrative Agent or the Joint Lead Arrangers constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

SECTION 9.07 Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof, and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

SECTION 9.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of any Borrower or its Restricted Subsidiaries against any of and all the obligations of the Borrowers or their Restricted Subsidiaries now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The applicable Lender shall notify the Borrowers and the Administrative Agent of each set-off or application, provided that any failure to give or any delay in giving such notice shall not affect the validity of any such set-off or application under this Section. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

SECTION 9.09 GOVERNING LAW; Jurisdiction; Consent to Service of Process.

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.

(d) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

SECTION 9.12 Confidentiality. Each of the Administrative Agent, the Issuing Bank and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’(involved in the extension of credit to the Borrowers) directors, officers, employees and agents, including accountants, rating agencies, portfolio management servicers, legal counsel, service providers and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement, (g) with the written consent of the Borrowers or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis from a source other than the Borrowers or any Subsidiary. In addition, each of the Administrative Agent, the Issuing Bank and the Lenders agrees that it will not, without the prior written consent of the Borrowers, reference the Borrowers or the Transactions in any advertisement, including any tombstones. In addition, each Lender, Agent and Issuing Bank may disclose the existence of this Agreement and the information about this Agreement to market data collectors and similar service providers to the lending industry, in each case, to the extent such information has been disclosed in Holdings’ periodic filings with the Securities and Exchange Commission or to the extent the Borrowers have given their prior written consent (such consent not to be unreasonably withheld or delayed). For the purposes of this Section, “Information” means all information received from the Borrowers or any of their Subsidiaries relating to the Borrowers or any of their Subsidiaries or their businesses, other than any such information that is available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by the Borrowers or any of their Subsidiaries; provided that, in the case of information received from the Borrowers or any of their Subsidiaries after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information. Notwithstanding anything herein to the contrary, each of the Administrative Agent, the Issuing Bank and the Lenders agrees that any information relating to the Credit Parties’ Customers or their contracts with its Customers shall not be disclosed to any Person (other than legal counsel) without Borrowers’ express written consent.

EACH LENDER ACKNOWLEDGES THAT INFORMATION AS DEFINED IN SECTION 9.12 FURNISHED TO IT PURSUANT TO THIS AGREEMENT MAY INCLUDE MATERIAL NON-PUBLIC INFORMATION CONCERNING HOLDINGS AND ITS AFFILIATES AND THEIR RELATED PARTIES OR THEIR RESPECTIVE SECURITIES, AND CONFIRMS THAT IT HAS DEVELOPED COMPLIANCE PROCEDURES REGARDING THE USE OF MATERIAL NON-PUBLIC INFORMATION AND THAT IT WILL HANDLE SUCH MATERIAL NON-PUBLIC INFORMATION IN ACCORDANCE WITH THOSE PROCEDURES AND APPLICABLE LAW, INCLUDING FEDERAL AND STATE SECURITIES LAWS.

ALL INFORMATION, INCLUDING REQUESTS FOR WAIVERS AND AMENDMENTS, FURNISHED BY THE BORROWERS OR THE ADMINISTRATIVE AGENT PURSUANT TO, OR IN THE COURSE OF ADMINISTERING, THIS AGREEMENT WILL BE SYNDICATE-LEVEL INFORMATION, WHICH MAY CONTAIN MATERIAL NON-PUBLIC INFORMATION ABOUT HOLDINGS, THE CREDIT PARTIES AND THEIR RELATED PARTIES OR THEIR RESPECTIVE SECURITIES. ACCORDINGLY, EACH LENDER REPRESENTS TO THE BORROWERS AND THE ADMINISTRATIVE AGENT THAT IT HAS IDENTIFIED IN ITS ADMINISTRATIVE QUESTIONNAIRE A CREDIT CONTACT WHO MAY RECEIVE INFORMATION THAT MAY CONTAIN MATERIAL NON-PUBLIC INFORMATION IN ACCORDANCE WITH ITS COMPLIANCE PROCEDURES AND APPLICABLE LAW, INCLUDING FEDERAL AND STATE SECURITIES LAWS.

SECTION 9.13 Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender.

SECTION 9.14 Subordination by Credit Parties. Each Borrower, individually and on behalf of each other Credit Party, hereby agrees that all present and future Indebtedness of any Credit Party to another Credit Party (“Intercompany Indebtedness”) shall be subordinate and junior in right of payment and priority to the Loans and all other obligations of the Borrowers and the other Credit Parties to the Administrative Agent and the Lenders, and each Borrower, individually and on behalf of each other Credit Party, agrees not to, during the existence of a Default, make, demand, accept or receive any payment in respect of any present or future Intercompany Indebtedness, including, without limitation, any payment received through the exercise of any right of setoff, counterclaim or cross claim, or any collateral therefor, unless and until such time as the Loans and all other obligations of the Borrowers and the other Credit Parties to the Administrative Agent and the Lenders shall have been indefeasibly paid in full. So long as no Default shall have occurred and be continuing and no Default shall be immediately caused thereby and such Intercompany Indebtedness is permitted by the terms of this Agreement, the Credit Parties may make and receive such payments in respect of any present or future Intercompany Indebtedness as shall be customary in the ordinary course of the Credit Parties’ business. Without in any way limiting the foregoing, in the event of any insolvency or bankruptcy proceedings, or any receivership, liquidation, reorganization, dissolution or other similar proceedings relative to any Credit Party or to its businesses, properties or assets, the Lenders shall be entitled to receive payment in full of the Loans and all other obligations of the Borrowers and the other Credit Parties to the Administrative Agent and the Lenders before any Credit Party shall be entitled to receive any payment in respect of any present or future Intercompany Indebtedness.

SECTION 9.15 USA Patriot Act. Each Lender hereby notifies the Credit Parties that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”), such Lender is required to obtain, verify and record information that identifies the Credit Parties, which information includes the name and address of each Credit Party and other information that will allow such Lender to identify such Credit Party in accordance with the Patriot Act.

SECTION 9.16 Qualifications Regarding Credit Party Disclosures. Notwithstanding anything to the contrary set forth herein, in no event shall any Credit Party be required to provide in any exhibit or schedule hereto, or in response to any disclosure required hereunder or any under Financing Document (including any annex, exhibit or schedule thereto), any information that is “classified” for reasons of national security or foreign policy under applicable laws, and each of the Credit Parties’ representations and warranties hereunder and thereunder and the annexes, exhibits and schedules hereto and thereto are so qualified.

SECTION 9.17 Restatement. As of the date hereof, the terms conditions, agreements, covenants, representations and warranties set forth in the Existing Credit Agreement are hereby amended, restated, replaced and superseded in their entirety by this Agreement, provided that nothing herein shall impair or adversely affect the continuation of the liability and obligations of the Credit Parties under the Existing Credit Agreement as amended hereby and nothing herein shall be construed to constitute payment of, or impair, limit, cancel or extinguish, or constitute a novation in respect of, the Indebtedness and other obligations and liabilities of the Credit Parties evidenced by or arising under the Existing Credit Agreement or the other Existing Financing Documents as amended hereby (it being understood, however, that accrued interest and fees under the Existing Credit Agreement are being paid by the Borrowers on the Effective Date in accordance with Section 4.01(p)), and the liens and security interests in favor of the Administrative Agent securing such Indebtedness and other obligations and liabilities, which shall not in any manner be impaired, limited, terminated, waived or released, except as expressly provided herein or in the other Financing Documents. Notwithstanding the foregoing, each party hereto acknowledges and agrees that non-compliance with any provision of the Existing Credit Agreement or the other Existing Financing Documents, if any, prior to the Effective Date is hereby waived.

and

The Lenders identified on the attached Schedule A

Ladies and Gentlemen:

We have acted as special counsel to USEC Inc., a Delaware corporation (“Holdings”), United States Enrichment Corporation, a Delaware corporation (“Enrichment,” and together with Holdings, each a “Borrower,” and collectively, the “Borrowers”), and NAC International Inc., a Delaware corporation (“NAC”), in connection with the Second Amended and Restated Revolving Credit Agreement, dated as of February [      ], 2010 (the “Credit Agreement”), among the Borrowers, JPMorgan Chase Bank, N.A., as administrative and collateral agent for the Lenders (in such capacity, “Agent”), the Lenders from time to time party thereto, and the arrangers, book managers and other agents named therein. We are providing this opinion to you pursuant to Section 4.01(b) of the Credit Agreement, at the request of you and the Opinion Parties (as defined below). Except as otherwise indicated, capitalized terms used in this opinion and defined in the Credit Agreement will have the meanings given in the Credit Agreement. Holdings, Enrichment and NAC are referred to herein collectively as the “Opinion Parties” and individually as an “Opinion Party.”

In our capacity as such counsel, we have examined originals or copies of the following documents (each dated as of the date hereof), such documents numbered 1 through 3 collectively referred to herein as the “Loan Documents”:

In our capacity as such counsel, we have also examined unfiled copies of the UCC-1 Financing Statements attached hereto as Schedule B naming (a) Holdings as debtor and Agent as secured party, which we understand will be filed with the Delaware Filing Office (as defined below) (the “Delaware UCC-1 Financing Statement – Holdings”), (b) Enrichment as debtor and Agent as Secured Party, which we understand will be filed with the Delaware Filing Office (the “Delaware UCC-1 Financing Statement – Enrichment”), and (c) NAC as debtor and Agent as Secured Party, which we understand will be filed with the Delaware Filing Office (the “Delaware UCC-1 Financing Statement – NAC” and together with the Delaware UCC-1 Financing Statement – Holding and, Delaware UCC-1 Financing Statement – Enrichment, the “Delaware UCC-1 Financing Statements”).

As to relevant factual matters, we have relied upon, among other things, the Opinion Parties’ factual representations in the Officer’s Certificates, without any investigation with respect to the truth and accuracy thereof. In addition, we have obtained and relied upon those certificates of public officials we considered appropriate.

We have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity with originals of all documents submitted to us as copies. To the extent the Opinion Parties’ obligations depend on the enforceability of the Loan Documents against the other parties thereto, we have assumed that the Loan Documents are enforceable against such other parties.

On the basis of such examination, our reliance upon the assumptions in this opinion and our consideration of those questions of law we considered relevant, and subject to the limitations and qualifications in this opinion, we are of the opinion that:

1. Each Opinion Party is a corporation validly existing and, based solely upon our review of good standing certificates received from the Delaware Secretary of State dated February 9, 2010 (with respect to Holdings and Enrichment) and February 1, 2010 (with respect to NAC), in good standing under the laws of the State of Delaware, with corporate power to (i) own its properties and assets, and (ii) enter into the Loan Documents to which it is a party and perform its obligations under the Loan Documents to which it is a party.

2. The execution, delivery and performance by each Opinion Party of the Loan Documents to which it is a party have been duly authorized by all necessary corporate action on the part of such Opinion Party, and such Loan Documents have been duly executed and delivered by such Opinion Party.

3. Each Loan Document to which an Opinion Party is a party constitutes the legally valid and binding obligation of such Opinion Party, enforceable against such Opinion Party in accordance with its terms, except as may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or affecting creditors’ rights generally (including, without limitation, fraudulent conveyance laws), the effect of Article Tenth of the Certificate of Incorporation of Holdings, and by general principles of equity, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance or injunctive relief, regardless of whether considered in a proceeding in equity or at law.

4. The execution and delivery by each Opinion Party of the Loan Documents to which it is a party do not, and each such Opinion Party’s performance of its obligations under such Loan Documents will not, violate such Opinion Party’s certificate of incorporation or bylaws.

5. The execution and delivery by each Opinion Party of the Loan Documents to which it is a party do not, and such Opinion Party’s performance of its obligations under such Loan Documents will not (i) breach or otherwise violate any existing obligation of or restriction on such Opinion Party under any order, judgment or decree of any New York or federal court or governmental authority binding on such Opinion Party identified in the Officer’s Certificates, or (ii) violate the current General Corporation Law of the State of Delaware or any current New York or federal statute, rule or regulation that we have, in the exercise of customary professional diligence, recognized as applicable to such Opinion Party or to transactions of the type contemplated by the Loan Documents.

6. No order, consent, permit or approval of, or filing with, any New York or federal governmental authority that we have, in the exercise of customary professional diligence, recognized as applicable to any Opinion Party or to transactions of the type contemplated by the Loan Documents is required on the part of any such Opinion Party for the execution and delivery of, and performance of its obligations under, the Loan Documents to which it is a party, except for (i) with respect to the performance of its obligations under the Loan Documents, routine informational filings required by applicable law, (ii) filings to perfect security interests and liens contemplated by the Loan Documents, (iii) with respect to the performance of its obligations under the Loan Documents, filings required to maintain the existence of such Opinion Party in good standing in applicable jurisdictions, (iv) with respect to the performance of its obligations under the Loan Documents, filings that may be required to perfect security interests and liens in connection with the Deferred Interests (as defined in the Security Agreement) and (v) with respect to the performance of its obligations under the Loan Documents, future filings in the ordinary course of business to comply with generally applicable regulatory or other laws or regulations applicable to such Opinion Party.

7. The Security Agreement is effective to create in favor of Agent as security for the Secured Obligations (as defined in the Security Agreement) a security interest in that Collateral (as defined in the Security Agreement) of the Opinion Parties in which a security interest may be created under Article 9 of the Uniform Commercial Code as in effect in the State of New York (the “Code”).

8. Upon the filing of the Delaware UCC-1 Financing Statements with the Secretary of State of the State of Delaware (the “Delaware Filing Office”), Agent will have a perfected security interest in the interest of the Opinion Parties in the Collateral (as defined in the Security Agreement) in which a security interest may be perfected under Delaware Article 9 (as defined below) by the filing of a financing statement in the State of Delaware.

9. The Security Agreement is effective to create under the Code in favor of Agent a security interest in the Certificated Securities (as defined below) identified on Annex A to the Security Agreement. Assuming (i) prior delivery of the certificates representing such Certificated Securities to Agent (and assuming such delivery occurred in New York), effectively endorsed to Agent or in blank, and (ii) that, following such delivery to Agent, such Certificated Securities have continued to be held by Agent in New York and, as of the date hereof, are held by Agent in New York, Agent has a perfected security interest in such Certificated Securities, free of adverse claims. For purposes of this paragraph 9, “Certificated Securities” means “certificated securities” as defined in Section 8-102 of the Code.

10. No Opinion Party is an “investment company” required to register under the Investment Company Act of 1940, as amended.

The opinions expressed above are subject to the following additional limitations, qualifications and exceptions:

(a) Our opinions in paragraph 3 above as to enforceability of the Loan Documents are subject to:

(i) public policy considerations, statutes or court decisions that may limit the rights of a party to obtain indemnification against its own negligence, willful misconduct or unlawful conduct;

(ii) the unenforceability under certain circumstances of broadly or vaguely stated waivers or waivers of rights granted by law where the waivers are against public policy or prohibited by law;

(iii) the unenforceability under certain circumstances of provisions imposing penalties, liquidated damages or other economic remedies;

(iv) the unenforceability under certain circumstances of provisions appointing one party as trustee for an adverse party or provisions for the appointment of a receiver; and

(v) the unenforceability of any provision purporting to release or require a release of future claims against the Agent or any Lender.

(b) We express no opinion as to the effect of non-compliance by you with any state or federal laws or regulations applicable to the transactions contemplated by the Loan Documents because of the nature of your business.

(c) We express no opinion as to any provision of any Loan Document insofar as it purports to grant a right of setoff in respect of any Opinion Party’s assets to any person other than a creditor of such Opinion Party.

(d) We advise you that any provision of any Loan Document which provides for exclusive jurisdiction of the courts of any particular State and federal courts sitting in such State may not be binding on the courts in the forums selected or excluded. We further advise you that, to the extent any opinion relates to the enforceability of New York choice of forum provisions of the Loan Documents, such provisions may not be binding on the federal courts sitting in the State of New York (or any federal appellate court).

(e) Our opinion in paragraph 3 is subject to the qualification that certain rights, remedies, waivers and other provisions of the Security Agreement may not be enforceable, but such unenforceability will not, subject to the other exceptions, qualifications and limitations set forth herein, render the Security Agreement invalid as a whole or substantially interfere with the substantial realization of the principal benefits or security, or both, that the Security Agreement purport to provide (except for the economic consequences of procedural or other delay).

(f) For purposes of the opinions expressed in paragraphs 4, 5 and 6, we have assumed that the Opinion Parties will not in the future take any discretionary action (including a decision not to act) permitted by the Loan Documents that would cause the performance of the Loan Documents to constitute a violation or breach of or default under the certificate of incorporation or by-laws of any Opinion Party or any order, judgment, or decree referred to in clause (i) of paragraph 3 or to violate the General Corporation Law of the State of Delaware or any New York or federal statute, rule or regulation, or to require an order, consent, approval or permit to be obtained from a New York or federal governmental authority.

(g) We express no opinion regarding any provision of any Loan Document that purports to permit Agent or any other person to sell or otherwise dispose of any collateral subject thereto except in compliance with the Code, any other applicable federal and state laws and any agreement governing such collateral, or to impose on Agent standards of care of collateral in Agent’s possession other than as provided in Section 9-207 of the Code. We advise you that federal and state securities laws may limit the right to transfer or dispose of collateral that may constitute securities under such laws.

(h) We express no opinion with respect to any goods which are accessions to, or commingled with, other goods to the extent that the security interest is limited by Section 9-335 or 9-336 of the Code.

(i) We express no opinion regarding the validity or perfection of the security interest as it relates to the Deferred Interests (as defined in the Security Agreement).

(A) a default in the payment when due (whether at the maturity thereof, or upon acceleration of maturity or otherwise and without giving effect to any applicable grace periods) of all or any portion of the Senior Indebtedness (whether of principal, interest or any other amount with respect thereto) shall have occurred, and such default shall not have been cured or waived in accordance with the terms of the Senior Debt Documents; or

(ii) Borrowers or any Senior Guarantor may resume payments (and may make any payments missed due to the application of Section X(c)(i)) in respect of the Subordinated Obligations or any judgment with respect thereto:

(A) in the case of a default referred to in clause (A) of Section X(c)(i), upon a cure or waiver thereof in accordance with the terms of the Senior Debt Documents; or

(B) in the case of an Event of Default or Events of Default referred to in clause (B) of Section X(c)(i), upon the earlier to occur of (x) the cure or waiver of all such Events of Default in accordance with the terms of the Senior Debt Documents, or (y) the expiration of such period of 180 days.

(iii) Following any acceleration of the maturity of any Senior Indebtedness and as long as such acceleration shall continue unrescinded and unannulled, such Senior Indebtedness shall first be paid in full, or provision for such payment shall be made in a manner reasonably satisfactory to the holders of the Senior Indebtedness, and all letters of credit issued under or in connection with the Senior Debt Documents shall first be fully cash collateralized, before any payment is made on account of or applied on the Subordinated Obligations.

(iv) Borrowers or any Senior Guarantor shall give prompt written notice to the Holder of (i) any default in respect of Senior Indebtedness referred to in Section X(c)(i)(A) and (ii) any notice of the type described in Section X(c)(i)(B) from the Senior Agent.

(r) When Distribution Must Be Paid Over. In the event that Holder shall receive any payment or distribution of assets that Holder is not entitled to receive or retain under the provisions of this Note, Holder shall hold any amount so received in trust for the holders of Senior Indebtedness, shall segregate such assets from other assets held by Holder and shall forthwith turn over such payment or distribution (without liability for interest thereon) to the Senior Agent on behalf of the holders of Senior Indebtedness in the form received (with any necessary endorsement) to be applied to the payment of the Senior Indebtedness and, following the payment in full of the Senior Indebtedness, to be held as cash collateral for all letters of credit issued under or in connection with the Senior Debt Documents. Notwithstanding the foregoing, if Holder receives a payment from any Borrower or any Senior Guarantor prior to receiving notice that such payment is restricted under the terms of Section X(c)(i) above, Holder may retain such payment.

(s) Exercise of Remedies. So long as any Senior Indebtedness is outstanding (including any loans, any letters of credit or any commitments to extend credit under the Senior Debt Documents), Holder (solely in its capacity as a holder of this Note) shall not exercise any rights or remedies with respect to an Event of Default under this Note, including, without limitation, any action (i) to demand or sue for collection of amounts payable hereunder, (ii) to accelerate the principal of this Note, or (iii) to commence, or join with any other creditor (other than the holder of a majority in principal amount of the Senior Indebtedness) in commencing, any proceeding in connection with or premised on the occurrence of a Bankruptcy Event prior to the earlier of

(A) the payment in full of all Senior Indebtedness, the expiration or cash collateralization in full of all letters of credit issued under or in connection with the Senior Debt Documents and the termination of all commitments to extend credit under the Senior Debt Documents;

(B) the initiation of a proceeding (other than a proceeding prohibited by clause (iii) of this Section X(e)) in connection with or premised upon the occurrence of a Bankruptcy Event;

(C) the expiration of 180 days immediately following the receipt by the Senior Agent of notice of the occurrence of such Event of Default from the Holder, and

(D) the acceleration of the maturity of the Senior Indebtedness;

provided however, that if, with respect to (B) and (D) above, such proceeding or acceleration, respectively, is rescinded, or with respect to (C) above, during such 180-day period such Event of Default has been cured or waived, the prohibition against taking the actions described in this Section X(e) shall automatically be reinstated as of the date of the rescission, cure or waiver, as applicable. In all events, unless an event described in clause (A), (B) or (D) above has occurred and not been rescinded, the Holder shall give thirty (30) days’ prior written notice to the Senior Agent before taking any action described in this Section X(e), which notice shall describe with specificity the action that the Holder in good faith intends to take.

(t) Acceleration of Payment of Note. If this Note is declared due and payable prior to the Maturity Date under this Note, no direct or indirect payment that is due solely by reason of such declaration shall be made, nor shall application be made of any distribution of assets of any Borrower or any Senior Guarantor (whether by set off or in any other manner, including, without limitation, from or by way of collateral) to the payment, purchase or other acquisition or retirement of this Note, unless, in either case, (i) all amounts due or to become due on or in respect of the Senior Indebtedness (including with respect to any outstanding letters of credit) shall have been previously paid in full, (ii) all letters of credit issued under or in connection with the Senior Debt Documents have terminated or expired or been cash collateralized in full and (iii) all commitments to extend credit under the Senior Credit Agreement shall have been terminated.

(u) Proceedings Against Borrowers and Senior Guarantors. So long as any Senior Indebtedness is outstanding (including any loans, letters of credit or any commitments to extend credit under the Senior Debt Documents), Holder (solely in its capacity as a holder of this Note) shall not commence any bankruptcy, insolvency, reorganization or other similar proceeding against any Borrower or any Senior Guarantor.

(v) Amending Senior Indebtedness. Any holder of Senior Indebtedness may, at any time and from time to time, without the consent of or notice to Holder (i) modify or amend the terms of the Senior Indebtedness, (ii) sell, exchange, release, fail to perfect a lien on or a security interest in or otherwise in any manner deal with or apply any property pledged or mortgaged to secure, or otherwise securing, Senior Indebtedness, (iii) release any Senior Guarantor or any other person liable in any manner for the Senior Indebtedness, (iv) exercise or refrain from exercising any rights against any Borrower, any Senior Guarantor or any other person, (v) apply any sums by whomever paid or however realized to the payment of the Senior Indebtedness or (vi) take any other action that might be deemed to impair in anyway the rights of Holder. Any and all of such actions may be taken by the holders of Senior Indebtedness without incurring responsibility to Holder and without impairing or releasing the obligations of Holder to the holders of Senior Indebtedness.

(w) Certain Rights in Bankruptcy. Holder hereby irrevocably authorizes and empowers each holder of Senior Indebtedness (and its representative or representatives) to demand, sue for, collect and receive all payments and distributions under the terms of this Note, to file and prove all claims (including claims in bankruptcy) relating to this Note, to exercise any right to vote arising with respect to this Note and any claims hereunder in any bankruptcy, insolvency or similar proceeding and take any and all other actions in the name of Holder (solely in its capacity as a holder of this Note), as such holder of Senior Indebtedness determines to be necessary or appropriate.

(x) Subrogation. No payment or distribution to any holder of Senior Indebtedness pursuant to the provisions of this Note shall entitle Holder to exercise any right of subrogation in respect thereof until (i)(x) all Senior Indebtedness shall have been paid in full, (y) all letters of credit issued under or in connection with the Senior Debt Documents have terminated or expired or been cash collateralized in full and (z) all commitments to extend credit under the Senior Debt Documents shall have been terminated or (ii) all holders of Senior Indebtedness have consented in writing to the taking of such action.

(y) Relative Rights. The provisions of this Section X are for the benefit of the holders of Senior Indebtedness (and their successors and assigns) and shall be enforceable by them directly against Holder. Holder acknowledges and agrees that any breach of the provisions of this Section X will cause irreparable harm for which the payment of monetary damages may be inadequate. For this reason, Holder agrees that, in addition to any remedies at law or equity to which a holder of Senior Indebtedness may be entitled, a holder of Senior Indebtedness will be entitled to an injunction or other equitable relief to prevent breaches of the provisions of this Section X and/or to compel specific performance of such provisions. The provisions of this Section X shall continue to be effective or be reinstated, as the case may be, if at any time any payment of the Senior Indebtedness is rescinded or must otherwise be returned by any holder of Senior Indebtedness upon the occurrence of a Bankruptcy Event or otherwise, all as though such payment had not been made. The provisions of this Section X are not intended to impair and shall not impair as between Borrowers or any Senior Guarantor and Holder, the obligation of Borrowers or any Senior Guarantor, which is absolute and unconditional, to pay Holder all amounts owing under this Note in accordance with its terms.

(z) Reliance on Orders and Decrees. Subject to the provisions of Section X(d) hereof, upon any payment or distribution of assets of any Borrower or any Senior Guarantor, whether in cash, property, securities or otherwise, Holder shall be entitled to rely upon any order or decree entered by any court of competent jurisdiction in which any insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution, winding up or similar case or proceeding is pending, or a certificate of the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit of creditors, agent or other person making such payment or distribution, delivered to Holder for the purpose of ascertaining the persons entitled to participate in such payment or distribution, the holders of Senior Indebtedness, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Section X.
