(b) If at any time any change in GAAP would affect the computation of any financial ratio set forth in any Loan Document, and either the Borrowers or the Required Lenders shall so request, the Administrative Agent and the Borrowers shall negotiate in good faith to amend such ratio to preserve the original intent thereof in light of such change in GAAP (subject to the approval of the Required Lenders and Borrowers); provided that, until so amended, (i) such ratio shall continue to be computed in accordance with GAAP prior to such change therein and (ii) the Borrowers shall provide to the Administrative Agent and the Lenders a written reconciliation in form and substance reasonably satisfactory to the Administrative Agent, between calculations of such ratio made before and after giving effect to such change in GAAP.

(c) Notwithstanding anything to the contrary contained herein, financial ratios and other financial calculations pursuant to this Agreement shall, following any Specified Transaction, be calculated on a Pro Forma Basis.

SECTION 1.04. Rounding. Any financial ratios required to be maintained by any Borrower pursuant to this Agreement (or required to be satisfied in order for a specific action to be permitted under this Agreement) shall be calculated by dividing the appropriate component by the other component, carrying the result to one place more than the number of places by which such ratio is expressed herein and rounding the result up or down to the nearest number (with a rounding-up if there is no nearest number).

SECTION 1.05. References to Agreements and Laws. Unless otherwise expressly provided herein, (a) references to Organization Documents, agreements (including the Loan Documents) and other contractual instruments shall be deemed to include all subsequent amendments, restatements, extensions, supplements and other modifications thereto, but only to the extent that such amendments, restatements, extensions, supplements and other modifications are not prohibited by any Loan Document; and (b) references to any Law shall include all statutory and regulatory provisions consolidating, amending, replacing, supplementing or interpreting such Law.

SECTION 1.06. Times of Day. Unless otherwise specified, all references herein to times of day shall be references to Eastern time (daylight or standard, as applicable).

SECTION 1.07. Timing of Payment or Performance. When the payment of any obligation or the performance of any covenant, duty or obligation is stated to be due or performance required on a day which is not a Business Day, the date of such payment (other than as described in the definition of Interest Period) or performance shall extend to the immediately succeeding Business Day and such extension of time shall be reflected in computing interest or fees, as the case may be.

ARTICLE 2

THE REVOLVING CREDIT COMMITMENTS AND CREDIT EXTENSIONS

SECTION 2.01. The Revolving Credit Loans. The Revolving Credit Borrowings. Subject to the terms and conditions set forth herein, each Lender severally agrees to make loans denominated in Dollars to any Borrower as elected by such Borrower pursuant to Section 2.02 (each such loan, a “Revolving Credit Loan”) from time to time, on any Business Day until the Maturity Date during the Revolving Credit Commitment Period, in an aggregate principal amount not to exceed at any time outstanding the amount of such Lender’s Revolving Credit Commitment; provided that (a) after giving effect to any Revolving Credit Borrowing, the aggregate Outstanding Amount of the Revolving Credit Loans of any Lender, plus the amount of such Lender’s Pro Rata Share of the Outstanding Amount of all L/C Obligations, plus such Lender’s Pro Rata Share of the Outstanding Amount of all Swing Line Loans, shall not exceed such Lender’s Revolving Credit Commitment, and (b) the amount of any Revolving Credit Loan to be made at any time shall not exceed Borrowing Availability at such time. Borrowing Availability may be reduced by Reserves and Lease Payment Reserves imposed by Agent in accordance with the provisions of Sections 2.15 and 2.16, as applicable. Within the limits of each Lender’s Revolving Credit Commitment, and subject to the other terms and conditions hereof (including as to Borrowing Availability), the Borrowers may borrow under this Section 2.01, prepay under Section 2.05, and reborrow under this Section 2.01. Revolving Credit Loans may be Base Rate Loans or Eurodollar Loans, as further provided herein; provided that all Revolving Credit Loans made by each of the Lenders pursuant to the same Borrowing shall, unless otherwise specifically provided herein, consist entirely of Revolving Credit Loans of the same Type.

Any provision of this Agreement to the contrary notwithstanding, at the request of Borrowers, in its discretion Administrative Agent may (but shall have absolutely no obligation to), make Revolving Credit Loans to the Borrowers on behalf of the Lenders, for the purpose of protecting or preserving the Collateral or any portion thereof, enhancing the likelihood of repayment of the Obligations or paying any other amount chargeable to borrower pursuant to the terms of this Agreement (including fees, costs and expenses described in Section 10.04), in amounts that cause the aggregate Outstanding Amount of the Revolving Credit Loans to exceed the Borrowing Base (less the Swing Line Loan) (any such excess aggregate Outstanding Amount of the Revolving Credit Loans are hereby collectively referred to as “Overadvances”); provided that (A) no such event or occurrence shall cause or constitute a waiver of the Administrative Agent’s, the Swing Line Lender’s or any Lender’s right to refuse to make

any further Overadvances, Swing Line Loans or Revolving Credit Loans, or incur any L/C Obligations, as the case may be, at any time that an Overadvance exists, and (B) no Overadvance shall result in a Default or Event of Default due to Borrowers’ failure to comply with Section 2.05(b) for so long as the Administrative Agent permits such Overadvance to remain outstanding, but solely with respect to the amount of such Overadvance. In addition, Overadvances may be made even if the conditions to lending set forth in Article 4 have not been met. All Overadvances shall constitute Base Rate Loans, shall bear interest at the Default Rate and shall be payable on the earlier of demand and the Termination Date. The authority of Administrative Agent to make Overadvances is limited to an aggregate amount of $10,000,000 at any time, shall not cause the Revolving Loan to exceed the Maximum Amount and may be revoked prospectively by a written notice to Administrative Agent signed by Required Lenders.

SECTION 2.02. Borrowings, Conversions and Continuations of Loans. (a) Each Revolving Credit Borrowing, each conversion of Revolving Credit Loans from one Type to the other, and each continuation of Eurodollar Rate Loans shall be made upon any Borrower’s irrevocable (except as provided in Section 3.02, Section 3.03 and Section 3.04 herein) notice to the Administrative Agent, which may be given by telephone. Each such notice must be received by the Administrative Agent (i) not later than 12:00 p.m. (noon) three (3) Business Days prior to the requested date of any Borrowing of Eurodollar Rate Loans, continuation of Eurodollar Rate Loans or any conversion of Base Rate Loans to Eurodollar Rate Loans, and (ii) not later than 12:00 p.m. (noon) on the requested date of any Borrowing of Base Rate Loans. Each telephonic notice by a Borrower pursuant to this Section 2.02(a) must be confirmed promptly by delivery to the Administrative Agent of a written Committed Loan Notice, appropriately completed and signed by a Responsible Officer of such Borrower. Each Borrowing of, conversion to or continuation of Eurodollar Rate Loans shall be in a minimum principal amount of $500,000 or a whole multiple of $250,000 in excess thereof. Except as provided in Section 2.03(c)(i) and Section 2.04(c)(i), each Borrowing of or conversion to Base Rate Loans shall be in a principal amount of $50,000 or a whole multiple of $50,000 in excess thereof. Each Committed Loan Notice (whether telephonic or written) shall specify (i) whether the relevant Borrower is requesting a Revolving Credit Borrowing, a conversion of Revolving Credit Loans from one Type to the other, or a continuation of Eurodollar Rate Loans, (ii) the requested date of the Borrowing, conversion or continuation, as the case may be (which shall be a Business Day), (iii) the principal amount of Loans to be borrowed, converted or continued, (iv) the Type of Loans to be borrowed or to which existing Revolving Credit Loans are to be converted, (v) if applicable, the duration of the Interest Period with respect thereto and (vi) the account of the relevant Borrower to be credited with the proceeds of such Borrowing. If, with respect to Loans denominated in Dollars the relevant Borrower fails to specify a Type of Loan in a Committed Loan Notice or fails to give a timely notice requesting a conversion or continuation, then the applicable Revolving Credit Loans shall be made as, or converted to, Base Rate Loans. Any such automatic conversion to Base Rate Loans shall be effective as of the last day of the Interest Period then in effect with respect to the applicable Eurodollar Rate Loans. If the relevant Borrower requests a Borrowing of, conversion to, or continuation of Eurodollar Rate Loans in any such Committed Loan Notice, but fails to specify an Interest Period, it will be deemed to have specified an Interest Period of one (1) month.

(b) Following receipt of a Committed Loan Notice, the Administrative Agent shall promptly notify each Appropriate Lender of the amount of its Pro Rata Share of the applicable Class of Loans, and if no timely notice of a conversion or continuation is provided by the relevant Borrower, the Administrative Agent shall notify each Lender of the details of any automatic conversion to Base Rate Loans or continuation described in Section 2.02(a). In the case of each Borrowing, each Appropriate Lender shall make the amount of its Loan available to the Administrative Agent in immediately available funds at the Administrative Agent’s Office not later than 12:00 p.m. (noon) on the Business Day specified in the applicable Committed Loan Notice. Upon satisfaction of the applicable conditions set forth in Section 4.02 (or, if such Borrowing is the initial Credit Extension, Section 4.01), the Administrative Agent shall make all funds so received available to the relevant Borrower in like funds as received by the

Administrative Agent by wire transfer of such funds in accordance with instructions provided to the Administrative Agent by such Borrower.

(c) Except as otherwise provided herein, a Eurodollar Rate Loan may be continued or converted only on the last day of an Interest Period for such Eurodollar Rate Loan unless the relevant Borrower pays the amount due, if any, under Section 3.05 in connection therewith. During the continuance of an Event of Default, the Administrative Agent or the Required Lenders may require that no Loans may be converted to or continued as Eurodollar Rate Loans.

(d) The Administrative Agent shall promptly notify the relevant Borrower and the Appropriate Lenders of the interest rate applicable to any Interest Period for Eurodollar Rate Loans upon determination of such interest rate. The determination of the Eurodollar Rate by the Administrative Agent shall be conclusive in the absence of manifest error. At any time that Base Rate Loans are outstanding, the Administrative Agent shall notify the relevant Borrower and the Appropriate Lenders of any change in the Administrative Agent’s prime rate used in determining the Base Rate promptly following the determination of such change.

(e) After giving effect to all Revolving Credit Borrowings, all conversions of Revolving Credit Loans from one Type to the other, and all continuations of Revolving Credit Loans as the same Type, there shall not be more than fifteen (15) Interest Periods in effect.

(f) The failure of any Lender to make the Loan to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its Loan on the date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Loan to be made by such other Lender on the date of any Borrowing.

SECTION 2.03. Letters of Credit. (a) The Letter of Credit Commitment. (i) Subject to the terms and conditions set forth herein, (A) the L/C Issuer agrees, in reliance upon the agreements of the other Lenders set forth in this Section 2.03, (1) from time to time on any Business Day during the period from the Closing Date until the Letter of Credit Expiration Date, to issue Letters of Credit denominated in Dollars for the account of the Borrowers (or any Restricted Subsidiary so long as a Borrower is a joint and several co-applicant, and references to a “Borrower” in this Section 2.03 shall be deemed to include reference to such Restricted Subsidiary) and to amend or renew Letters of Credit previously issued by it, in accordance with Section 2.03(b), and (2) to honor drafts under the Letters of Credit; and (B) the Lenders severally agree to participate in Letters of Credit issued for the account of the relevant Borrower; provided that the L/C Issuer shall not be obligated to make any L/C Credit Extension with respect to any Letter of Credit, and no Lender shall be obligated to participate in any Letter of Credit if, as of the date of such L/C Credit Extension, (x) the aggregate Outstanding Amount of the Revolving Credit Loans of any Lender, plus such Lender’s Amount of Pro Rata Share of the Outstanding Amount of all L/C Obligations, plus such Lender’s Pro Rata Share of the Outstanding Amount of all Swing Line Loans, would exceed such Lender’s Revolving Credit Commitment, or (y) the Outstanding Amount of the L/C Obligations would exceed the Letter of Credit Sublimit, or (z) the aggregate Outstanding Amount of the Revolving Credit Loans, plus the Outstanding Amount of all L/C Obligations, plus the Outstanding Amount of all Swing Line Loans, would exceed the Borrowing Base; provided further that the Initial L/C Issuer shall not be obligated to make any L/C Credit Extension with respect to any Letter of Credit, if, as of the date of such L/C Credit Extension, the Outstanding Amount of the L/C Obligations issued by the Initial L/C issuer would exceed $5,000,000. Within the foregoing limits, and subject to the terms and conditions hereof, the relevant Borrower’s ability to obtain Letters of Credit shall be fully revolving, and accordingly such Borrower may, during the foregoing period, obtain Letters of Credit to replace Letters of Credit that have expired or that have been drawn upon and reimbursed.

(ii) The L/C Issuer shall be under no obligation to issue any Letter of Credit if:

(A) any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain the L/C Issuer from issuing such Letter of Credit, or any Law applicable to the L/C Issuer or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over the L/C Issuer shall prohibit, or request that the L/C Issuer refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon the L/C Issuer with respect to such Letter of Credit any restriction, reserve or capital requirement (for which the L/C Issuer is not otherwise compensated hereunder) not in effect on the Closing Date, or shall impose upon the L/C Issuer any unreimbursed loss, cost or expense which was not applicable on the Closing Date and which, in each case, the L/C Issuer in good ▇▇▇▇▇ ▇▇▇▇▇ material to it;

(B) subject to Section 2.03(b)(iii), the expiry date of such requested Letter of Credit, prior to giving effect to any automatic renewal, would occur more than twelve months after the date of issuance or last renewal, unless the Required Lenders have approved such expiry date;

(C) the expiry date of such requested Letter of Credit would occur after the Letter of Credit Expiration Date, unless all the Lenders have approved such expiry date; or

(D) the issuance of such Letter of Credit would violate any Laws or one or more policies of the L/C Issuer.

(iii) The L/C Issuer shall be under no obligation to amend any Letter of Credit if (A) the L/C Issuer would have no obligation at such time to issue such Letter of Credit in its amended form under the terms hereof, or (B) the beneficiary of such Letter of Credit does not accept the proposed amendment to such Letter of Credit.

(b) Procedures for Issuance and Amendment of Letters of Credit; Auto-Renewal Letters of Credit. (i) Each Letter of Credit shall be issued or amended, as the case may be, upon the request of the relevant Borrower delivered to the L/C Issuer (with a copy to the Administrative Agent) in the form of a Letter of Credit Application, appropriately completed and signed by a Responsible Officer of such Borrower. Such Letter of Credit Application must be received by the L/C Issuer and the Administrative Agent not later than 1:00 p.m. at least two (2) days, or such shorter period as mutually agreed, prior to the proposed issuance date or date of amendment, as the case may be (provided that in each case the applicable Borrower has delivered a Letter of Credit Application, appropriately completed and signed by a Responsible Officer of such Borrower and has provided satisfactory language with respect to the applicable beneficiary of such Letter of Credit), or such later date and time as the L/C Issuer may agree in a particular instance in its sole discretion. In the case of a request for an initial issuance of a Letter of Credit, such Letter of Credit Application shall specify in form and detail reasonably satisfactory to the L/C Issuer: (A) the proposed issuance date of the requested Letter of Credit (which shall be a Business Day); (B) the amount thereof; (C) the expiry date thereof; (D) the name and address of the beneficiary thereof; (E) the documents to be presented by such beneficiary in case of any drawing thereunder; (F) the full text of any certificate to be presented by such beneficiary in case of any drawing thereunder; and (G) such other matters as the L/C Issuer may reasonably request. In the case of a request for an amendment of any outstanding Letter of Credit, such Letter of Credit Application shall specify in form and detail reasonably satisfactory to the L/C Issuer: (A) the Letter of Credit to be amended; (B) the proposed date

of amendment thereof (which shall be a Business Day); (C) the nature of the proposed amendment; and (D) such other matters as the L/C Issuer may reasonably request.

(ii) Promptly after receipt of any Letter of Credit Application, the L/C Issuer will confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has received a copy of such Letter of Credit Application from the relevant Borrower and, if not, the L/C Issuer will provide the Administrative Agent with a copy thereof. Upon receipt by the L/C Issuer of confirmation from the Administrative Agent that the requested issuance or amendment is permitted in accordance with the terms hereof (such confirmation to be promptly provided by the Administrative Agent), then, subject to the terms and conditions hereof, the L/C Issuer shall, on the requested date, issue a Letter of Credit for the account of the relevant Borrower or enter into the applicable amendment, as the case may be. Immediately upon the issuance of each Letter of Credit, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the L/C Issuer an unfunded risk participation in such Letter of Credit in an amount equal to the product of such Lender’s Pro Rata Share times the amount of such Letter of Credit.

(iii) If the relevant Borrower so requests in any applicable Letter of Credit Application, the L/C Issuer may, in its sole and absolute discretion, agree to issue a Letter of Credit that has automatic renewal provisions (each, an “Auto-Renewal Letter of Credit”); provided that any such Auto-Renewal Letter of Credit must permit the L/C Issuer to prevent any such renewal at least once in each twelve month period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not later than a day (the “Nonrenewal Notice Date”) in each such twelve month period to be agreed upon at the time such Letter of Credit is issued. Unless otherwise directed by the L/C Issuer, no Borrower shall be required to make a specific request to the L/C Issuer for any such renewal. Once an Auto-Renewal Letter of Credit has been issued, the Lenders shall be deemed to have authorized (but may not require) the L/C Issuer to permit the renewal of such Letter of Credit at any time to an expiry date not later than the Letter of Credit Expiration Date; provided that the L/C Issuer shall not permit any such renewal if (A) the L/C Issuer has determined that it would have no obligation at such time to issue such Letter of Credit in its renewed form under the terms hereof (by reason of the provisions of Section 2.03(a)(ii) or otherwise), or (B) it has received notice (which may be by telephone or in writing) on or before the day that is five (5) Business Days before the Nonrenewal Notice Date (1) from the Administrative Agent that the Required Lenders have elected not to permit such renewal or (2) from the Administrative Agent, any Lender or any Borrower that one or more of the applicable conditions specified in Section 4.02 is not then satisfied.

(iv) Promptly after its delivery of any Letter of Credit or any amendment to a Letter of Credit to an advising bank with respect thereto or to the beneficiary thereof, the L/C Issuer will also deliver to the relevant Borrower and the Administrative Agent a true and complete copy of such Letter of Credit or amendment.

(c) Drawings and Reimbursements; Funding of Participations. (i) Upon receipt from the beneficiary of any Letter of Credit of any notice of a drawing under such Letter of Credit, the L/C Issuer shall notify the relevant Borrower and the Administrative Agent thereof. Not later than 12:00 p.m. (noon) on the Business Day immediately following any payment by the L/C Issuer under a Letter of Credit (each such date, an “Honor Date”), the relevant Borrower shall reimburse the L/C Issuer through the Administrative Agent in an amount equal to the amount of such drawing (with interest, if not on the same date). If any Borrower fails to so reimburse the L/C Issuer by such time, the Administrative Agent shall promptly notify each Lender of the Honor Date, the amount of the unreimbursed drawing (the

“Unreimbursed Amount”), and the amount of such Lender’s Pro Rata Share thereof. In such event, the relevant Borrower shall be deemed to have requested a Revolving Credit Borrowing of Base Rate Loans to be disbursed on the Honor Date in an amount equal to the Unreimbursed Amount, without regard to the minimum and multiples specified in Section 2.02(a) for the principal amount of Base Rate Loans but subject to the amount of the unutilized portion of the Revolving Credit Commitments and the conditions set forth in Section 4.02 (other than the delivery of a Committed Loan Notice). Any notice given by the L/C Issuer or the Administrative Agent pursuant to this Section 2.03(c)(i) may be given by telephone if promptly confirmed in writing; provided that the lack of a prompt confirmation shall not affect the conclusiveness or binding effect of such notice.

(ii) Each Lender (including the Lender acting as the L/C Issuer) shall upon any notice pursuant to Section 2.03(c)(i) make funds available to the Administrative Agent for the account of the L/C Issuer, in Dollars, at the Administrative Agent’s Office in an amount equal to its Pro Rata Share of the Unreimbursed Amount not later than 1:00 p.m. on the Business Day specified in such notice by the Administrative Agent, whereupon, subject to the provisions of Section 2.03(c)(iii), each Lender that so makes funds available shall be deemed to have made a Base Rate Loan to the relevant Borrower in such amount. The Administrative Agent shall remit the funds so received to the L/C Issuer.

(iii) With respect to any Unreimbursed Amount that is not fully refinanced by a Revolving Credit Borrowing of Base Rate Loans because the conditions set forth in Section 4.02 cannot be satisfied or for any other reason, or if a reimbursement to the L/C Issuer shall be required to be returned or disgorged for any reason (including by reason of the commencement of a proceeding of the type described in Section 8.01(f)), the relevant Borrower shall be deemed to have incurred from the L/C Issuer an L/C Borrowing in the amount of the Unreimbursed Amount that is not so refinanced, which L/C Borrowing shall be due and payable on demand (together with interest) and shall bear interest at the Default Rate. In such event, each Lender’s payment to the Administrative Agent for the account of the L/C Issuer pursuant to Section 2.03(c)(ii) shall be deemed payment in respect of its participation in such L/C Borrowing and shall constitute an L/C Advance from such Lender in satisfaction of its participation obligation under this Section 2.03.

(iv) Until each Lender funds its Revolving Credit Loan or L/C Advance pursuant to this Section 2.03(c) to reimburse the L/C Issuer for any amount drawn under any Letter of Credit, interest in respect of such Lender’s Pro Rata Share of such amount shall be solely for the account of the L/C Issuer.

(v) Each Lender’s obligation to make Revolving Credit Loans or L/C Advances to reimburse the L/C Issuer for amounts drawn under Letters of Credit, as contemplated by this Section 2.03(c), shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against the L/C Issuer, any Borrower or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided that each Lender’s obligation to make Revolving Credit Loans pursuant to this Section 2.03(c) is subject to the conditions set forth in Section 4.02 (other than delivery by the relevant Borrower of a Committed Loan Notice). No such making of an L/C Advance shall relieve or otherwise impair the obligation of the relevant Borrower to reimburse the L/C Issuer for the amount of any payment made by the L/C Issuer under any Letter of Credit, together with interest as provided herein.

(vi) If any Lender fails to make available to the Administrative Agent for the account of the L/C Issuer any amount required to be paid by such Lender pursuant to the foregoing

provisions of this Section 2.03(c) by the time specified in Section 2.03(c)(ii), the L/C Issuer shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the L/C Issuer at a rate per annum equal to the applicable Federal Funds Rate from time to time in effect. A certificate of the L/C Issuer submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this Section 2.03(c)(vi) shall be conclusive absent manifest error.

(d) Repayment of Participations. (i) If, at any time after the L/C Issuer has made a payment under any Letter of Credit and has received from any Lender such Lender’s L/C Advance in respect of such payment in accordance with Section 2.03(c), the Administrative Agent receives for the account of the L/C Issuer any payment in respect of the related Unreimbursed Amount or interest thereon (whether directly from the relevant Borrower or otherwise, including proceeds of Cash Collateral applied thereto by the Administrative Agent), the Administrative Agent will distribute to such Lender its Pro Rata Share thereof (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s L/C Advance was outstanding) in the same funds as those received by the Administrative Agent.

(ii) If any payment received by the Administrative Agent for the account of the L/C Issuer pursuant to Section 2.03(d)(i) is required to be returned under any of the circumstances described in Section 10.06 (including pursuant to any settlement entered into by the L/C Issuer in its discretion), each Lender shall pay to the Administrative Agent for the account of the L/C Issuer its Pro Rata Share thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned by such Lender, at a rate per annum equal to the applicable Federal Funds Rate from time to time in effect.

(e) Obligations Absolute. The obligation of each Borrower to reimburse the L/C Issuer for each drawing under each Letter of Credit issued for its account and to repay each L/C Borrowing relating to any Letter of Credit issued for its account shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including the following:

(i) any lack of validity or enforceability of such Letter of Credit, this Agreement, or any other agreement or instrument relating thereto;

(ii) the existence of any claim, counterclaim, setoff, defense or other right that such Borrower or the applicable other Borrower or applicable Restricted Subsidiary may have at any time against any beneficiary or any transferee of such Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), the L/C Issuer or any other Person, whether in connection with this Agreement, the transactions contemplated hereby or by such Letter of Credit or any agreement or instrument relating thereto, or any unrelated transaction;

(iii) any draft, demand, certificate or other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; or any loss or delay in the transmission or otherwise of any document required in order to make a drawing under such Letter of Credit;

(iv) any payment by the L/C Issuer under such Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of such Letter of Credit; or any payment made by the L/C Issuer under such Letter of Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of creditors, liquidator,

receiver or other representative of or successor to any beneficiary or any transferee of such Letter of Credit, including any arising in connection with any proceeding under any Debtor Relief Law;

(v) any exchange, release or nonperfection of any Collateral, or any release or amendment or waiver of or consent to departure from the Guaranty or any other guarantee, for all or any of the Obligations of such Borrower in respect of such Letter of Credit; or

(vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, including any other circumstance that might otherwise constitute a defense available to, or a discharge of, such Borrower;

provided that the foregoing shall not excuse the L/C Issuer from liability to such Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are waived by such Borrower to the extent permitted by applicable Law) suffered by such Borrower that are determined by a nonappealable judgment of a court of competent jurisdiction to have been caused by the L/C Issuer’s gross negligence, bad faith or willful misconduct when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. Each Borrower shall promptly examine a copy of each Letter of Credit issued for its account and each amendment thereto that is delivered to it and, in the event of any claim of noncompliance with such Borrower’s instructions or other irregularity, such Borrower will promptly notify the L/C Issuer. Each Borrower shall be conclusively deemed to have waived any such claim against the L/C Issuer and its correspondents unless such notice is given as aforesaid.

(f) Role of L/C Issuer. Each Lender and each Borrower agree that, in paying any drawing under a Letter of Credit, the L/C Issuer shall not have any responsibility to obtain any document (other than any sight draft, certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the authority of the Person executing or delivering any such document. None of the L/C Issuer, any Agent-Related Person nor any of the respective correspondents, participants or assignees of the L/C Issuer shall be liable to any Lender for (i) any action taken or omitted in connection herewith at the request or with the approval of the Lenders or the Required Lenders, as applicable; (ii) any action taken or omitted in the absence of gross negligence or willful misconduct; or (iii) the due execution, effectiveness, validity or enforceability of any document or instrument related to any Letter of Credit or Letter of Credit Application. Each Borrower hereby assumes all risks of the acts or omissions of any beneficiary or transferee with respect to its use of any Letter of Credit; provided that this assumption is not intended to, and shall not, preclude such Borrower’s pursuing such rights and remedies as it may have against the beneficiary or transferee at Law or under any other agreement. None of the L/C Issuer, any Agent-Related Person, nor any of the respective correspondents, participants or assignees of the L/C Issuer, shall be liable or responsible for any of the matters described in clauses (i) through (vi) of Section 2.03(e); provided that anything in such clauses to the contrary notwithstanding, each relevant Borrower may have a claim against the L/C Issuer, and the L/C Issuer may be liable to such Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential or exemplary, damages suffered by such Borrower which such Borrower proves were caused by the L/C Issuer’s willful misconduct, bad faith or gross negligence or the L/C Issuer’s willful or grossly negligent or bad faith failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit. In furtherance and not in limitation of the foregoing, the L/C Issuer may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and the L/C Issuer shall not be responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason.

(g) Cash Collateral. Upon the request of the Administrative Agent, (i) if the L/C Issuer has honored any full or partial drawing request under any Letter of Credit and such drawing has resulted in an L/C Borrowing and the conditions set forth in Section 4.02 to a Revolving Credit Borrowing cannot then be met, or (ii) if, as of the Letter of Credit Expiration Date, any Letter of Credit may for any reason remain outstanding and partially or wholly undrawn, the relevant Borrower shall promptly Cash Collateralize (x) in the case of clause (i), 100% and (y) in the case of clause (ii), 103%, in each case, the then Outstanding Amount of all L/C Obligations (such Outstanding Amount to be determined as of the date of such L/C Borrowing or the Letter of Credit Expiration Date, as the case may be) or, in the case of clause (ii), provide a back to back letter of credit in a face amount at least equal to 103% of the then undrawn amount of such Letter of Credit from an issuer and in form and substance reasonably satisfactory to the L/C Issuer in its reasonable discretion. Any Letter of Credit that is so Cash Collateralized or in respect of which such a back-to-back letter of credit shall have been issued shall be deemed no longer outstanding for purposes of this Agreement. For purposes hereof, “Cash Collateralize” means to pledge and deposit with or deliver to the Administrative Agent, for the benefit of the L/C Issuer and the Lenders, as collateral for the L/C Obligations, cash or deposit account balances (“Cash Collateral”) pursuant to documentation in form and substance reasonably satisfactory to the Administrative Agent and the L/C Issuer (which documents are hereby consented to by the Lenders). Derivatives of such term have corresponding meanings. Cash Collateral shall be maintained in deposit accounts designated by the Administrative Agent and which is under the sole dominion and control of the Administrative Agent and shall be deposited in an interest-bearing account. If at any time the Administrative Agent determines that any funds held as Cash Collateral are subject to any right or claim of any Person other than the Administrative Agent or claims of the depositary bank arising by operation of law or that the total amount of such funds is less than the amount required by the first sentence of this clause (g), the relevant Borrower will, forthwith upon demand by the Administrative Agent, pay to the Administrative Agent, as additional funds to be deposited and held in the deposit accounts designated by the Administrative Agent as aforesaid, an amount equal to the excess of (x) 100% or 103%, as applicable, of such aggregate Outstanding Amount over (y) the total amount of funds, if any, then held as Cash Collateral that the Administrative Agent reasonably determines to be free and clear of any such right and claim. Upon the drawing of any Letter of Credit for which funds are on deposit as Cash Collateral, such funds shall be applied, to the extent permitted under applicable Law, to reimburse the L/C Issuer. To the extent the amount of any Cash Collateral exceeds 100% or 103%, as applicable, of the then Outstanding Amount of such L/C Obligations and so long as no Event of Default has occurred and is continuing, the excess shall be refunded to the relevant Borrower.

(h) Applicability of ISP98 and UCP. Unless otherwise expressly agreed by the L/C Issuer and the relevant Borrower when a Letter of Credit is issued, (i) the rules of the “International Standby Practices 1998” published by the Institute of International Banking Law & Practice (or such later version thereof as may be in effect at the time of issuance) (excluding Rule 3.14) shall apply to each standby Letter of Credit, and (ii) the rules of the Uniform Customs and Practice for Documentary Credits, as most recently published by the International Chamber of Commerce at the time of issuance shall apply to each commercial Letter of Credit.

(i) Letter of Credit Fees. Each Borrower shall pay to the Administrative Agent for the account of each Lender in accordance with its Pro Rata Share a Letter of Credit fee for each Letter of Credit issued for the account of such Borrower equal to the Applicable Rate times the daily maximum amount then available to be drawn under such Letter of Credit. Such letter of credit fees shall be computed on a quarterly basis in arrears. Such letter of credit fees shall be due and payable on the last Business Day of each March, June, September and December, commencing with the first such date to occur after the issuance of such Letter of Credit, on the Letter of Credit Expiration Date and thereafter on demand. If there is any change in the Applicable Rate during any quarter, the daily maximum amount of

each Letter of Credit shall be computed and multiplied by the Applicable Rate separately for each period during such quarter that such Applicable Rate was in effect.

(j) Fronting Fee and Documentary and Processing Charges Payable to L/C Issuer. Each Borrower shall pay directly to the L/C Issuer for its own account a fronting fee with respect to each Letter of Credit issued for the account of such Borrower equal to 0.25% per annum of the daily maximum amount then available to be drawn under such Letter of Credit. Such fronting fees shall be computed on a quarterly basis in arrears. Such fronting fees shall be due and payable on the last Business Day of each March, June, September and December, commencing with the first such date to occur after the issuance of such Letter of Credit, on the Letter of Credit Expiration Date and thereafter on demand. In addition, each Borrower shall pay directly to the L/C Issuer for its own account the customary issuance, presentation, amendment and other processing fees, and other standard costs and charges, of the L/C Issuer relating to letters of credit as from time to time in effect. Such customary fees not related to the fronting fee and standard costs and charges are due and payable within five (5) Business Days of written demand by the L/C Issuer setting forth in reasonable detail such costs and charges and are nonrefundable.

(k) Conflict with Letter of Credit Application. In the event of any conflict between the terms hereof and the terms of any Letter of Credit Application, the terms of this Agreement shall control.

SECTION 2.04. Swing Line Loans. (a) The Swing Line. Subject to the terms and conditions set forth herein, the Swing Line Lender agrees to make loans (each such loan, a “Swing Line Loan”) to each Borrower from time to time on any Business Day (other than the Closing Date) during the Revolving Credit Commitment Period in an aggregate amount not to exceed at any time outstanding the least of (i) the amount of the Swing Line Sublimit, and (ii) the lesser of the Revolving Credit Commitment and the Borrowing Base, in each case, less the outstanding balance of the Revolving Credit Loans and outstanding L/C Obligations at such time, notwithstanding the fact that such Swing Line Loans, when aggregated with the Pro Rata Share of the Outstanding Amount of Loans and L/C Obligations of the Lender acting as Swing Line Lender, may exceed the amount of such Lender’s Commitment; provided that after giving effect to any Swing Line Loan, the aggregate Outstanding Amount of the Revolving Credit Loans of any Lender, plus such Lender’s Pro Rata Share of the Outstanding Amount of all L/C Obligations, plus such Lender’s Pro Rata Share of the amount of the Outstanding Amount of all Swing Line Loans shall not exceed such Lender’s Revolving Credit Commitment; provided further that (x) no Borrower shall use the proceeds of any Swing Line Loan to refinance any outstanding Swing Line Loan, and (y) the aggregate principal amount of the Swing Line Loans outstanding to the Borrowers shall not exceed at any time the Borrowing Base less the Revolving Credit Loans and the Outstanding Amount of all L/C Obligations outstanding to the Borrowers. Within the foregoing limits, and subject to the other terms and conditions hereof, the Borrowers may borrow under this Section 2.04, prepay under Section 2.05, and reborrow under this Section 2.04. Each Swing Line Loan shall be a Base Rate Loan. Swing Line Loans shall only be denominated in Dollars. Immediately upon the making of a Swing Line Loan, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Swing Line Lender an unfunded risk participation in such Swing Line Loan in an amount equal to the product of such Lender’s Pro Rata Share times the amount of such Swing Line Loan.

(b) Borrowing Procedures. Each Swing Line Borrowing shall be made upon the relevant Borrower’s irrevocable notice to the Swing Line Lender and the Administrative Agent, which may be given by telephone. Each such notice must be received by the Swing Line Lender and the Administrative Agent not later than 1:00 p.m. on the requested borrowing date, and shall specify (i) the amount to be borrowed, which shall be a minimum of $100,000 (ii) the requested borrowing date, which shall be a Business Day and (iii) the account of the relevant Borrower to be credited with the proceeds of such Swing Line Borrowing. Each such telephonic notice must be confirmed promptly by delivery to the

Swing Line Lender and the Administrative Agent of a written Swing Line Loan Notice, appropriately completed and signed by a Responsible Officer of the relevant Borrower. Promptly after receipt by the Swing Line Lender of any telephonic Swing Line Loan Notice, the Swing Line Lender will confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has also received such Swing Line Loan Notice and, if not, the Swing Line Lender will notify the Administrative Agent (by telephone or in writing) of the contents thereof. Unless the Swing Line Lender has received notice (by telephone or in writing) from the Administrative Agent (including at the request of any Lender) prior to 2:00 p.m. on the date of such proposed Swing Line Borrowing (A) directing the Swing Line Lender not to make such Swing Line Loan as a result of the limitations set forth in the first proviso to the first sentence of Section 2.04(a), or (B) that one or more of the applicable conditions specified in Section 4.02 is not then satisfied, then, subject to the terms and conditions hereof, the Swing Line Lender will, not later than 3:00 p.m. on the borrowing date specified in such Swing Line Loan Notice, make the amount of its Swing Line Loan available to the relevant Borrower.

(c) Refinancing of Swing Line Loans. (i) The Swing Line Lender at any time in its sole and absolute discretion may request, but no less frequently than weekly, on behalf of the relevant Borrower (each of which hereby irrevocably authorizes the Swing Line Lender to so request on its behalf), that each Lender make a Base Rate Loan in an amount equal to such Lender’s Pro Rata Share of the amount of Swing Line Loans then outstanding. Each such request shall be made in writing (which written request shall be deemed to be a Committed Loan Notice for purposes hereof) and in accordance with the requirements of Section 2.02(a), without regard to the minimum and multiples specified therein for the principal amount of Base Rate Loans, but subject to the unutilized portion of the aggregate Revolving Credit Commitments and the conditions set forth in Section 4.02. The Swing Line Lender shall furnish the relevant Borrower with a copy of the applicable Committed Loan Notice promptly after delivering such notice to the Administrative Agent. Each Lender shall make an amount equal to its Pro Rata Share of the amount specified in such Committed Loan Notice available to the Administrative Agent in immediately available funds for the account of the Swing Line Lender at the Administrative Agent’s Office not later than 1:00 p.m. on the day specified in such Committed Loan Notice, whereupon, subject to Section 2.04(c)(ii), each Lender that so makes funds available shall be deemed to have made a Base Rate Loan to the relevant Borrower in such amount. The Administrative Agent shall remit the funds so received to the Swing Line Lender.

(ii) If for any reason any Swing Line Loan cannot be refinanced by such a Revolving Credit Borrowing in accordance with Section 2.04(c)(i), or if a reimbursement to the Swing Line Lender shall be required to be returned or disgorged for any reason (including by reason of the commencement of a proceeding of the type described in Section 8.01(f)), the request for Base Rate Loans submitted by the Swing Line Lender as set forth herein shall be deemed to be a request by the Swing Line Lender that each of the Lenders fund its risk participation in such Swing Line Loan and each such Lender’s payment to the Administrative Agent for the account of the Swing Line Lender pursuant to Section 2.04(c)(i) shall be deemed payment in respect of such participation.

(iii) If any Lender fails to make available to the Administrative Agent for the account of the Swing Line Lender any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.04(c) by the time specified in Section 2.04(c)(i), the Swing Line Lender shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the Swing Line Lender at a rate per annum equal to the applicable Federal Funds Rate from time to time in effect. A certificate of the Swing Line Lender submitted to any Lender (through the Administrative Agent)

with respect to any amounts owing under this clause (iii) shall be conclusive absent manifest error.

(iv) Each Lender’s obligation to make Revolving Credit Loans or to purchase and fund risk participations in Swing Line Loans pursuant to this Section 2.04(c) shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against the Swing Line Lender, any Borrower or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided that each Lender’s obligation to make Revolving Credit Loans pursuant to this Section 2.04(c) is subject to the conditions set forth in Section 4.02 (other than delivery by a Borrower of a Committed Loan Notice). No such funding of risk participations shall relieve or otherwise impair the obligation of the relevant Borrower to repay Swing Line Loans, together with interest as provided herein.

(d) Repayment of Participations. (i) At any time after any Lender has purchased and funded a risk participation in a Swing Line Loan, if the Swing Line Lender receives any payment on account of such Swing Line Loan, the Swing Line Lender will distribute to such Lender its Pro Rata Share of such payment (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s risk participation was funded) in the same funds as those received by the Swing Line Lender.

(ii) If any payment received by the Swing Line Lender in respect of principal or interest on any Swing Line Loan is required to be returned by the Swing Line Lender under any of the circumstances described in Section 10.06 (including pursuant to any settlement entered into by the Swing Line Lender in its discretion), each Lender shall pay to the Swing Line Lender its Pro Rata Share thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned, at a rate per annum equal to the applicable Federal Funds Rate. The Administrative Agent will make such demand upon the request of the Swing Line Lender.

(e) Interest for Account of Swing Line Lender. The Swing Line Lender shall be responsible for invoicing the relevant Borrower for interest on the Swing Line Loans. Until each Lender funds its Base Rate Loan or risk participation pursuant to this Section 2.04 to refinance such Lender’s Pro Rata Share of any Swing Line Loan, interest in respect of such Pro Rata Share shall be solely for the account of the Swing Line Lender.

(f) Payments Directly to Swing Line Lender. The relevant Borrower shall make all payments of principal and interest in respect of the Swing Line Loans directly to the Swing Line Lender.

SECTION 2.05. Prepayments. (a) Optional. (i) Any Borrower may, upon notice to the Administrative Agent, at any time or from time to time voluntarily prepay Loans made to such Borrower, in each case, in whole or in part without premium or penalty; provided that (A) such notice must be received by the Administrative Agent not later than 12:00 p.m. (noon) (1) three (3) Business Days prior to any date of prepayment of Eurodollar Rate Loans and (2) on the date of prepayment of Base Rate Loans; (B) any prepayment of Eurodollar Rate Loans shall be in a principal amount of $500,000 or a whole multiple of $250,000 in excess thereof or, if less, the entire principal amount thereof then outstanding; and (C) any prepayment of Base Rate Loans shall be in a principal amount of $50,000 or a whole multiple of $50,000 in excess thereof or, if less, the entire principal amount thereof then outstanding. Each such notice shall specify the date and amount of such prepayment and the Class(es) and Type(s) of Loans to be prepaid. The Administrative Agent will promptly notify each Appropriate

Lender of its receipt of each such notice, and of the amount of such Lender’s Pro Rata Share of such prepayment. If such notice is given by a Borrower, such Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein. Any prepayment of a Eurodollar Rate Loan shall be accompanied by all accrued interest thereon, together with any additional amounts required pursuant to Section 3.05. Each prepayment made by a Borrower in respect of a particular Facility shall be paid to the Administrative Agent for the account of (and to be promptly disbursed to) the Appropriate Lenders in accordance with their respective Pro Rata Shares.

(ii) Either Borrower may, upon notice to the Swing Line Lender (with a copy to the Administrative Agent), at any time or from time to time, voluntarily prepay Swing Line Loans in whole or in part without premium or penalty; provided that (1) such notice must be received by the Swing Line Lender and the Administrative Agent not later than 12:00 p.m. (noon) on the date of the prepayment, and (2) any such prepayment shall be in a minimum principal amount of $100,000 or, if less, the entire principal amount thereof then outstanding. Each such notice shall specify the date and amount of such prepayment. If such notice is given by either Borrower, such Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein.

(iii) Notwithstanding anything to the contrary contained in this Agreement, any relevant Borrower may rescind any notice of prepayment under Section 2.05(a)(i) or Section 2.05(a)(ii) if such prepayment would have resulted from a refinancing of all of the Facilities, which refinancing shall not be consummated or shall otherwise be delayed.

(b) Mandatory. (i) If for any reason the aggregate Outstanding Amount of the Revolving Credit Loans, the L/C Obligations and Swing Line Loans at any time exceeds the aggregate Revolving Credit Commitments then in effect, the Borrowers shall promptly prepay Revolving Credit Loans or Swing Line Loans and/or Cash Collateralize the L/C Obligations in an aggregate amount equal to such excess; provided that the Borrowers shall not be required to Cash Collateralize the L/C Obligations pursuant to this Section 2.05(b)(ii) unless after the prepayment in full of the Revolving Credit Loans and Swing Line Loans such aggregate Outstanding Amount exceeds such aggregate Revolving Credit Commitments then in effect.

(ii) If on any date on which a Borrowing Base Certificate or a Alternative Borrowing Base, as the case may be, is delivered pursuant to Section 6.01(e), the aggregate outstanding balance of the Revolving Credit Loans, the L/C Obligations and the Swing Line Loans exceeds the Borrowing Base, as calculated therein, the Borrowers shall, no later than the Business Day immediately following the date of delivery of such Borrowing Base Certificate or Alternative Borrowing Base, as applicable, prepay the Revolving Credit Loans or Swing Line Loans and/or Cash Collateralize the L/C Obligations in an aggregate amount equal to such excess; provided that the Borrowers shall not be required to Cash Collateralize the L/C Obligations pursuant to this Section 2.05(b)(ii) unless after the prepayment in full of the Revolving Credit Loans and Swing Line Loans such aggregate Outstanding Amount exceeds such aggregate Borrowing Base then in effect.

(iii) Funding Losses, Etc. All prepayments under this Section 2.05 shall be made together with, in the case of any such prepayment of a Eurodollar Rate Loan on a date other than the last day of an Interest Period therefor, any amounts owing in respect of such Eurodollar Rate Loan, pursuant to Section 3.05. Notwithstanding any of the other provisions of Section 2.05(b), so long as no Event of Default shall have occurred and be continuing, if any prepayment of Eurodollar Rate Loans is required to be made under this Section 2.05(b), other than on the last day of the Interest Period therefor, the Borrowers may, in their sole discretion, deposit the amount

of any such prepayment otherwise required to be made thereunder into a Cash Collateral Account until the last day of such Interest Period, at which time the Administrative Agent shall be authorized (without any further action by or notice to or from such Borrowers or any other Loan Party) to apply such amount to the prepayment of such Loans in accordance with this Section 2.05(b). Upon the occurrence and during the continuance of any Event of Default, the Administrative Agent shall also be authorized (without any further action by or notice to or from a Borrower or any other Loan Party) to apply such amount to the prepayment of the outstanding Loans in accordance with this Section 2.05(b).

SECTION 2.06. Termination or Reduction of Revolving Credit Commitments. (a) Optional. The Borrowers may, upon written notice to the Administrative Agent, terminate all or any portion of the unused Revolving Credit Commitments under the Revolving Credit Facility; provided that (i) any such notice shall be received by the Administrative Agent three (3) Business Days prior to the date of termination or reduction, (ii) any such partial reduction shall be in an aggregate amount (A) of $1,000,000 or any whole multiple of $100,000 in excess thereof or (B) equal to the entire remaining amount of the Revolving Credit Commitments and (iii) if, after giving effect to any reduction of the Revolving Credit Commitments, (1) the Letter of Credit Sublimit or the Swing Line Sublimit, as the case may be, exceeds the amount of the Revolving Credit Commitments, such sublimit shall be automatically reduced by the amount of such excess. The amount of any such Revolving Credit Commitment reduction shall not be applied to the Letter of Credit Sublimit or the Swing Line Sublimit unless otherwise specified by the Borrowers. Notwithstanding the foregoing, the Borrowers may rescind or postpone any notice of termination of the Revolving Credit Commitments if such termination would have resulted from a refinancing of all of the Facilities, which refinancing shall not be consummated or otherwise shall be delayed.

(b) Application of Revolving Credit Commitment Reductions; Payment of Fees. The Administrative Agent will promptly notify the Appropriate Lenders of any termination or reduction of unused portions of the Letter of Credit Sublimit or the Swing Line Sublimit or the unused Revolving Credit Commitments of any Class under this Section 2.06. Upon any reduction of unused Revolving Credit Commitments of any Class, the Revolving Credit Commitment of each Lender of such Class shall be reduced by such Lender’s Pro Rata Share of the amount by which such Revolving Credit Commitments are reduced (other than the termination of the Revolving Credit Commitment of any Lender as provided in Section 3.07). All commitment fees accrued until the effective date of any termination of the Aggregate Commitments of any Class shall be paid to the Appropriate Lenders on the effective date of such termination.

SECTION 2.07. Repayment of Loans. (a) Revolving Credit Loans. Each Borrower shall repay to the Administrative Agent for the ratable account of the applicable Lenders on the Maturity Date for the Revolving Credit Facility the aggregate principal amount of all of its Revolving Credit Loans outstanding on such date.

(b) Swing Line Loans. Each Borrower shall repay the aggregate principal amount of all of its Swing Line Loans on the Maturity Date for the Revolving Credit Facility.

(c) Additional Revolving Credit Loans. The relevant Borrower shall repay the aggregate amount of any Additional Revolving Credit Loans to the Administrative Agent on the maturity date to be agreed by such Borrower and the relevant Additional Lenders.

SECTION 2.08. Interest. (a) Subject to the provisions of Section 2.08(b), (i) each Eurodollar Rate Loan shall bear interest on the outstanding principal amount thereof for each Interest Period at a rate per annum equal to the Eurodollar Rate for such Interest Period plus the Applicable Rate;

(ii) each Base Rate Loan shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to the Base Rate plus the Applicable Rate; and (iii) each Swing Line Loan shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to the Base Rate plus the Applicable Rate for Revolving Credit Loans.

(b) While any Event of Default set forth in Section 8.01(a) exists, each Borrower shall pay interest on the overdue principal amount of all of its outstanding Obligations hereunder at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws. Accrued and unpaid interest on past due amounts (including interest on past due interest) shall be due and payable upon demand.

(c) Interest on each Loan shall be due and payable in arrears on each Interest Payment Date applicable thereto and at such other times as may be specified herein. Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment, and before and after the commencement of any proceeding under any Debtor Relief Law.

SECTION 2.09. Fees. In addition to certain fees described in Section 2.03(i) and Section 2.03(j):

(a) Revolving Credit Commitment Fee. The Borrowers shall pay to the Administrative Agent for the account of each Lender in accordance with its Pro Rata Share, a commitment fee (each, a “Revolving Credit Commitment Fee” and, collectively, the “Revolving Credit Commitment Fees”) equal to the Applicable Commitment Fee Rate times the actual daily amount by which the aggregate Revolving Credit Commitments exceed the sum of (i) the Outstanding Amount of Revolving Credit Loans (exclusive of any Swing Line Loans) and (ii) the Outstanding Amount of L/C Obligations; provided that any Revolving Credit Commitment Fee accrued with respect to the Revolving Credit Commitment of a Defaulting Lender during the period prior to the time such Lender became a Defaulting Lender and unpaid at such time shall not be payable by the Borrowers so long as such Lender shall be a Defaulting Lender except to the extent that such Revolving Credit Commitment Fee shall otherwise have been due and payable by the Borrowers prior to such time; and provided further that no Revolving Credit Commitment Fee shall accrue on the Revolving Credit Commitment of a Defaulting Lender so long as such Lender shall be a Defaulting Lender. The Revolving Credit Commitment Fees shall accrue at all times from the date hereof until the Maturity Date for the Revolving Credit Facility, including at any time during which one or more of the conditions in Article 4 is not met, and shall be due and payable quarterly in arrears on the last Business Day of each March, June, September and December, commencing with the first such date to occur after the Closing Date, and on the Maturity Date for the Revolving Credit Facility. The Revolving Credit Commitment Fees shall be calculated quarterly in arrears, and if there is any change in the Applicable Rate during any quarter, the actual daily amount shall be computed and multiplied by the Applicable Rate separately for each period during such quarter that such Applicable Rate was in effect.

(b) Other Fees. The Borrowers shall pay or cause to be paid to the Agents such fees as shall have been separately agreed upon in writing in the amounts and at the times so specified. Such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever (except as expressly agreed between the Borrowers and the applicable Agent).

SECTION 2.10. Computation of Interest and Fees. All computations of interest for Base Rate Loans when the Base Rate is determined by reference to the “Prime Rate” as published by Bloomberg Professional Service Page Prime shall be made on the basis of a year of three hundred and sixty-five (365) or three hundred and sixty-six (366) days, as the case may be, and actual days elapsed.

All other computations of fees and interest shall be made on the basis of a three hundred and sixty (360) day year and actual days elapsed (which results in more fees or interest, as applicable, being paid than if computed on the basis of a three hundred and sixty-five (365) day year). Interest shall accrue on each Loan for the day on which the Loan is made, and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid; provided that any Loan that is repaid on the same day on which it is made shall, subject to Section 2.12(a), bear interest for one (1) day. Each determination by the Administrative Agent of an interest rate or fee hereunder shall be conclusive and binding for all purposes, absent manifest error.

SECTION 2.11. Evidence of Indebtedness. (a) The Credit Extensions made by each Lender shall be evidenced by one or more accounts or records maintained by such Lender and evidenced by one or more entries in the Register maintained by the Administrative Agent, acting solely for purposes of Treasury Regulation Section 5f.103-1(c), as agent for the Borrowers, in each case in the ordinary course of business. The accounts or records maintained by the Administrative Agent and each Lender shall be prima facie evidence absent manifest error of the amount of the Credit Extensions made by the Lenders to the Borrowers and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrowers hereunder to pay any amount owing with respect to the Obligations. In the event of any conflict between the accounts and records maintained by any Lender and the accounts and records of the Administrative Agent in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. Upon the request of any Lender made through the Administrative Agent, the relevant Borrowers shall execute and deliver to such Lender (through the Administrative Agent) a Note payable to such Lender, which shall evidence such Lender’s Loans in addition to such accounts or records. Each Lender may attach schedules to its Note and endorse thereon the date, Type (if applicable), amount and maturity of its Loans and payments with respect thereto. Each Borrower and each Lender agrees from time to time after the occurrence and during the continuance of an Event of Default under Section 8.01(f) or Section 8.01(g)(i) to execute and deliver to the Administrative Agent all such Notes or other promissory notes and other instruments and documents as the Administrative Agent shall reasonably request to evidence and confirm the respective interests and obligations of the Lenders after giving effect to any exchange of Lenders’ interests pursuant to arrangements relating thereto among the Lenders, and each Lender agrees to surrender any Notes or other promissory notes originally received by it in connection with its Loans hereunder to the Administrative Agent against delivery of any Notes or other promissory notes so executed and delivered.

(b) In addition to the accounts and records referred to in Section 2.11(a), each Lender and the Administrative Agent shall maintain in accordance with its usual practice accounts or records and, in the case of the Administrative Agent, entries in the Register, evidencing the purchases and sales by such Lender of participations in Letters of Credit and Swing Line Loans. In the event of any conflict between the accounts and records maintained by the Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error.

(c) Entries made in good faith by the Administrative Agent in the Register pursuant to Section 2.11(a) and Section 2.11(b), and by each Lender in its account or accounts pursuant to Section 2.11(a) and Section 2.11(b), shall be prima facie evidence of the amount of principal and interest due and payable or to become due and payable from the Borrowers to, in the case of the Register, each Lender and, in the case of such account or accounts, such Lender, under this Agreement and the other Loan Documents, absent manifest error; provided that the failure of the Administrative Agent or such Lender to make an entry, or any finding that an entry is incorrect, in the Register or such account or accounts shall not limit or otherwise affect the obligations of the Borrowers under this Agreement and the other Loan Documents.

SECTION 2.12. Payments Generally. (a) All payments to be made by the Borrowers shall be made without condition or deduction for any counterclaim, defense, recoupment or setoff. Except as otherwise expressly provided herein, all payments by the Borrowers hereunder shall be made to the Administrative Agent, for the account of the respective Lenders to which such payment is owed, at the Administrative Agent’s Office in Dollars and in immediately available funds not later than 2:00 p.m. on the date specified herein. The Administrative Agent will promptly distribute to each Lender its Pro Rata Share (or other applicable share as provided herein) of such payment in like funds as received by wire transfer to such Lender’s Lending Office. All payments received by the Administrative Agent after 4:00 p.m. shall be deemed received on the next succeeding Business Day in the Administrative Agent’s sole discretion and any applicable interest or fee shall continue to accrue to the extent applicable.

(b) If any payment to be made by any Borrower shall come due on a day other than a Business Day in relation to such Borrower, payment shall be made on the next following Business Day, and such extension of time shall be reflected in computing interest or fees, as the case may be; provided that, if such extension would cause payment of interest on or principal of Eurodollar Rate Loans to be made in the next succeeding calendar month, such payment shall be made on the immediately preceding Business Day.

(c) Unless any Borrower or any Lender has notified the Administrative Agent, prior to the date any payment is required to be made by it to the Administrative Agent hereunder, that such Borrower or such Lender, as the case may be, will not make such payment, the Administrative Agent may assume that such Borrower or such Lender, as the case may be, has timely made such payment and may (but shall not be so required to), in reliance thereon, make available a corresponding amount to the Person entitled thereto. If and to the extent that such payment was not in fact made to the Administrative Agent in immediately available funds, then:

(i) if any Borrower failed to make such payment, each Lender shall forthwith on demand repay to the Administrative Agent the portion of such assumed payment that was made available to such Lender in immediately available funds, together with interest thereon in respect of each day from and including the date such amount was made available by the Administrative Agent to such Lender to the date such amount is repaid to the Administrative Agent in immediately available funds at the applicable Federal Funds Rate from time to time in effect; and

(ii) if any Lender failed to make such payment, such Lender shall forthwith on demand pay to the Administrative Agent the amount thereof in immediately available funds, together with interest thereon for the period from the date such amount was made available by the Administrative Agent to the relevant Borrower to the date such amount is recovered by the Administrative Agent (the “Compensation Period”) at a rate per annum equal to the applicable Federal Funds Rate from time to time in effect. When such Lender makes payment to the Administrative Agent (together with all accrued interest thereon), then such payment amount (excluding the amount of any interest which may have accrued and been paid in respect of such late payment) shall constitute such Lender’s Loan included in the applicable Borrowing. If such Lender does not pay such amount forthwith upon the Administrative Agent’s demand therefor, the Administrative Agent may make a demand therefor upon the relevant Borrower, and the relevant Borrower shall pay such amount to the Administrative Agent, together with interest thereon for the Compensation Period at a rate per annum equal to the rate of interest applicable to the applicable Borrowing. Nothing herein shall be deemed to relieve any Lender from its obligation to fulfill its Revolving Credit Commitment or to prejudice any rights which the Administrative Agent or any Borrower may have against any Lender as a result of any default by such Lender hereunder.

A notice of the Administrative Agent to any Lender or any relevant Borrower with respect to any amount owing under this Section 2.12(c) shall be conclusive, absent manifest error.

(d) If any Lender makes available to the Administrative Agent funds for any Loan to be made by such Lender as provided in the foregoing provisions of this Article 2, and such funds are not made available to the relevant Borrower by the Administrative Agent because the conditions to the applicable Credit Extension set forth in Article 4 are not satisfied or waived in accordance with the terms hereof, the Administrative Agent shall return such funds (in like funds as received from such Lender) to such Lender, without interest.

(e) The obligations of the Lenders hereunder to make Loans and to fund participations in Letters of Credit and Swing Line Loans are several and not joint. The failure of any Lender to make any Loan or to fund any such participation on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its Loan or purchase its participation.

(f) Nothing herein shall be deemed to obligate any Lender to obtain the funds for any Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for any Loan in any particular place or manner.

(g) Whenever any payment received by the Administrative Agent under this Agreement or any of the other Loan Documents is insufficient to pay in full all amounts due and payable to the Administrative Agent and the Lenders under or in respect of this Agreement and the other Loan Documents on any date, such payment shall be distributed by the Administrative Agent and applied by the Administrative Agent and the Lenders in the order of priority set forth in Section 8.03. If the Administrative Agent receives funds for application to the Obligations of the Loan Parties under or in respect of the Loan Documents under circumstances for which the Loan Documents do not specify the manner in which such funds are to be applied, the Administrative Agent may, but shall not be obligated to, elect to distribute such funds to each of the Lenders in accordance with such Lender’s Pro Rata Share of the sum of (i) the Outstanding Amount of all Loans outstanding at such time and (ii) the Outstanding Amount of all L/C Obligations outstanding at such time, in repayment or prepayment of such of the outstanding Loans or other Obligations then owing to such Lender. In the absence of a specific determination by the Administrative Agent, payments shall be applied to amounts then due and payable in the following order: (i) to fees, expenses of the Agents reimbursable hereunder and Indemnified Liabilities of the Agents hereunder, (ii) to interest on the Swing Line Loans, (iii) to principal payments on the Swing Line Loans, (iv) to interest on the Revolving Credit Loans, (v) to principal payments on the Revolving Credit Loans and to provide Cash Collateralize L/C Obligations, ratably to the aggregate combined principal amount of the Revolving Credit Loans and outstanding L/C Obligations, and (vi) to all other Obligations, including expenses of Lenders hereunder to the extent reimburseable under Section 10.04 and all Indemnified Liabilities of Lenders.

SECTION 2.13. Sharing of Payments. If, other than as expressly provided elsewhere herein, any Lender shall obtain on account of the Loans made by it, or the participations in L/C Obligations or in Swing Line Loans held by it, any payment (whether voluntary, involuntary, through the exercise of any right of setoff, or otherwise) in excess of its ratable share (or other share contemplated hereunder) thereof, such Lender shall immediately (a) notify the Administrative Agent of such fact, and (b) purchase from the other Lenders such participations in the Loans made by them and/or such subparticipations in the participations in L/C Obligations or Swing Line Loans held by them, as the case may be, as shall be necessary to cause such purchasing Lender to share the excess payment in respect of such Loans or such participations, as the case may be, pro rata with each of them; provided that if all or any portion of such excess payment is thereafter recovered from the purchasing Lender under any of the

circumstances described in Section 10.06 (including pursuant to any settlement entered into by the purchasing Lender in its discretion), such purchase shall to that extent be rescinded and each other Lender shall repay to the purchasing Lender the purchase price paid therefor, together with an amount equal to such paying Lender’s ratable share (according to the proportion of (i) the amount of such paying Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered, without further interest thereon. Each Borrower agrees that any Lender so purchasing a participation from another Lender may, to the fullest extent permitted by Law, exercise all its rights of payment (including the right of setoff, but subject to Section 10.09) with respect to such participation as fully as if such Lender were the direct creditor of such Borrower in the amount of such participation. The Administrative Agent will keep records (which shall be conclusive and binding in the absence of manifest error) of participations purchased under this Section 2.13 and will in each case notify the Lenders following any such purchases or repayments. Each Lender that purchases a participation pursuant to this Section 2.13 shall from and after such purchase have the right to give all notices, requests, demands, directions and other communications under this Agreement with respect to the portion of the Obligations purchased to the same extent as though the purchasing Lender were the original owner of the Obligations purchased.

SECTION 2.14. Increase in Revolving Credit Commitments. (a) Upon notice to the Administrative Agent, at any time after the Closing Date, the Borrowers may request Additional Revolving Credit Commitments; provided that (i) after giving effect to any such addition, the aggregate amount of Additional Revolving Credit Commitments that have been added pursuant to this Section 2.14 shall not exceed $50,000,000, (ii) any such addition shall be in an aggregate amount of $15,000,000 or any whole multiple of $1,000,000 in excess thereof, (iii) the final maturity date of any Additional Revolving Credit Loans shall be no earlier than the Maturity Date for the Revolving Credit Loans, and (iv) such Additional Revolving Credit Commitments shall be first offered to the then existing Lenders, which shall have a right of first refusal (but not an obligation) to increase their revolving Credit Commitments by a pro rata amount, and any such lenders which become party hereto which are not then Lenders shall be subject to the approval of the Administrative Agent and the Borrowers (such approval not to be unreasonably withheld).

(b) If any Additional Revolving Credit Commitments are added in accordance with this Section 2.14, the Administrative Agent and the applicable Borrower shall determine the effective date (the “Additional Commitments Effective Date”) and the final amount of such addition. The Administrative Agent shall promptly notify the applicable Borrower and the Lenders (which may include Persons reasonably acceptable to the Administrative Agent and the applicable Borrower that were not Lenders prior to the Additional Commitments Effective Date) of the final amount of such addition and the Additional Commitments Effective Date. As a condition precedent to such addition, the Borrowers shall deliver to the Administrative Agent a certificate of the Borrowers dated as of the Additional Commitments Effective Date signed by a Responsible Officer of each Borrower certifying that, before and after giving effect to such increase, (i) the representations and warranties contained in Article 5 and the other Loan Documents are true and correct in all material respects on and as of the Additional Commitments Effective Date, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they shall have been true and correct in all material respects as of such earlier date, and except that for purposes of this Section 2.14(b), the representations and warranties contained in Section 5.05(a) and Section 5.05(b) shall be deemed to refer to the most recent financial statements furnished pursuant to subsections (a) and (b), respectively, of Section 6.01, (ii) no Default or Event of Default exists immediately before or immediately after giving effect to such addition, (iii) UHS and its Restricted Subsidiaries shall be in Pro Forma Compliance with the financial covenant set forth in Section 7.11 as of (A) the Additional Commitments Effective Date and (B) the last day of the most recently ended determination period after giving Pro Forma Effect to such Additional Revolving Credit

Commitment, as applicable, the making of Additional Revolving Credit Loans, as the case may be, in respect thereof and any Investment or Disposition to be consummated in connection therewith. On each Additional Commitments Effective Date, each applicable Lender, Eligible Assignee or other Person which is providing an Additional Revolving Credit Commitment shall become a “Lender”, as applicable, for all purposes of this Agreement and the other Loan Documents.

(c) Any other terms of and documentation entered into in respect of any Additional Revolving Credit Commitments provided, in each case pursuant to this Section 2.14, to the extent not consistent with the Revolving Credit Commitments, as the case may be, shall be reasonably satisfactory to the Administrative Agent. Any Additional Revolving Credit Commitments, as applicable, made or provided pursuant to this Section 2.14 shall be evidenced by one or more entries in the Register maintained by the Administrative Agent in accordance with the provisions set forth in Section 2.11.

(d) This Section 2.14 shall supersede any provisions in Section 10.01 to the contrary. Notwithstanding any other provision of any Loan Document, the Loan Documents may be amended by the Administrative Agent and the Loan Parties, if necessary, to provide for terms applicable to each Additional Revolving Credit Commitment.

SECTION 2.15. Eligible Accounts and Eligible Unbilled Accounts. All of the Accounts owned by Borrowers and their Subsidiaries and reflected in the most recent Borrowing Base Certificate (to the extent required to be reflected pursuant to Section 6.01(e)) delivered by Borrowers to Administrative Agent shall be “Eligible Accounts” or, as applicable, “Eligible Unbilled Accounts” for purposes of this Agreement, except any Account to which any of the exclusionary criteria set forth below applies.

ARTICLE 3

TAXES, INCREASED COSTS PROTECTION AND ILLEGALITY

SECTION 3.01. Taxes. (a) Except as provided in this Section 3.01, any and all payments by any Borrower to or for the account of any Agent or any Lender under any Loan Document shall be made free and clear of and without deduction for any and all present or future taxes, duties, levies, imposts, deductions, assessments, fees, withholdings or similar charges, and all liabilities (including additions to tax, penalties and interest) with respect thereto, excluding, in the case of each Agent and each Lender, (i) taxes imposed on or measured by its net income and franchise (and similar) taxes imposed on it in lieu of net income taxes, by the United States and the jurisdiction (or any political subdivision thereof) under the Laws of which such Agent or such Lender, as the case may be, is organized or in which its principal office is located or in the case of any Lender, in which its Lending Office is

located, and (ii) any branch profits tax imposed by the United States, and all liabilities (including additions to tax, penalties and interest) with respect thereto (all such non-excluded taxes, duties, levies, imposts, deductions, assessments, fees, withholdings or similar charges, and liabilities being hereinafter referred to as “Taxes”). If any Borrower shall be required by any Laws to deduct any Taxes from or in respect of any sum payable under any Loan Document to any Agent or any Lender, (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 3.01), each of such Agent and such Lender receives an amount equal to the sum it would have received had no such deductions been made, (ii) such Borrower shall make such deductions, (iii) such Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable Laws, and (iv) within thirty (30) days after the date of such payment, such Borrower shall furnish to such Agent or Lender (as the case may be) the original or a certified copy of a receipt evidencing payment thereof to the extent such a receipt is issued therefor, or other written proof of payment thereof that is reasonably satisfactory to the Administrative Agent; provided that no Borrower shall be obligated to make any such payment to any Agent or any Lender (as the case may be) in respect of penalties, interest and other liabilities attributable to Taxes or Other Taxes if and to the extent that such penalties, interest and other liabilities are attributable to the gross negligence or willful misconduct of such Agent or such Lender (as the case may be); provided further that if any Borrower reasonably believes that such taxes were not correctly or legally asserted by any Agent or Any Lender, such Agent or such Lender, as the case may be, will use reasonable efforts to cooperate with the Borrowers to obtain a refund of such taxes so long as such efforts would not, in the sole determination of the Agent or such Lender (as the case may be) result in any additional costs, expenses or risks or be otherwise disadvantageous to it.

(b) In addition, each Borrower agrees to pay any and all present or future stamp, court or documentary taxes and any other excise, property, intangible or mortgage recording taxes or charges or similar levies which arise from any payment made under any Loan Document or from the execution, delivery, performance, enforcement or registration of, or otherwise with respect to, any Loan Document (hereinafter referred to as “Other Taxes”).

(c) Each Borrower agrees to indemnify each Agent and each Lender for (i) the full amount of Taxes and Other Taxes(including any Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this Section 3.01) paid by such Agent and such Lender, and (ii) any liability (including additions to tax, penalties, interest and expenses) arising therefrom or with respect thereto, in each case whether or not such Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority; provided that such Agent or Lender, as the case may be, provides such Borrower with a written statement thereof setting forth in reasonable detail the basis and calculation of such amounts. Payment under this Section 3.01(c) shall be made within thirty (30) days after the date such Lender or such Agent makes a written demand therefor. Notwithstanding anything contained in this Section 3.01 to the contrary, the Borrowers shall be under no obligation to any Agent or any Lender with respect to any additional amounts described in subsections (a), (b) and (c) of this Section 3.01 to the extent incurred prior to the one hundred-eightieth (180th) day preceding the date on which the Borrowers received notice by such Agent or such Lender of such additional amounts, unless the requirement resulting in such additional amounts becomes effective during such 180 day period and retroactively applies to a date occurring prior to such 180 day period, in which case the Borrowers shall be responsible for all such additional amounts described in subsections (a), (b) and (c) of this Section 3.01 from and after such date of effectiveness.

(d) No Borrower shall be required pursuant to this Section 3.01 to pay any additional amount to, or to indemnify, any Lender or Agent, as the case may be, to the extent that such Lender or such Agent becomes subject to Taxes subsequent to the Closing Date (or, if later, the date such Lender or Agent becomes a party to this Agreement) as a result of a change in the place of organization of such Lender or

Agent or a change in the Lending Office of such Lender, except to the extent that any such change is requested or required in writing by any Borrower (and provided that nothing in this clause (d) shall be construed as relieving any Borrower from any obligation to make such payments or indemnification in the event of a change in Lending Office or place of organization that precedes a change in Law to the extent such Taxes result from a change in Law).

(e) If a Lender or an Agent is subject to United States withholding tax at a rate in excess of zero percent at the time such Lender or such Agent, as the case may be, first becomes a party to this Agreement, withholding tax at such rate (or at a lesser rate to which such Lender or Agent is entitled under an applicable treaty) at such time shall be considered excluded from Taxes; provided that, if at the date of the Assignment and Assumption pursuant to which a Lender becomes a party to this Agreement, the Lender assignor was entitled to payments under clause (a) of this Section 3.01 in respect of United States withholding tax with respect to interest paid at such date, then, to such extent, the term Taxes shall include (in addition to withholding taxes that may be imposed in the future or other amounts otherwise includable in Taxes) United States withholding tax, if any, applicable with respect to the Lender assignee on such date. Any Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located or any treaty to which the Netherlands is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the appropriate Agent), at the reasonable written request of the Borrower, 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; provided that such Lender is legally entitled to complete, execute and deliver such documentation and in such Lender’s judgment such completion, execution or delivery would not materially prejudice the legal position of such Lender; and provided further, that if any form or document referred to in this Section 3.01 requires the disclosure of information, other than information necessary to compute the tax payable and information required on the date hereof by the relevant taxing authority, that the applicable Lender or Agent considers to be confidential, such Lender or Agent shall give notice thereof to the Borrower and shall not be obligated to include in such form or document such confidential information.

(f) If any Lender or Agent shall become aware that it is entitled to receive a refund in respect of amounts paid by any Borrower pursuant to this Section 3.01, which refund in the good faith judgment of such Lender or Agent is allocable to such payment, it shall promptly notify such Borrower of the availability of such refund and shall, within thirty (30) days thereafter, apply for such refund; provided that in the sole judgment of the Lender or Agent, applying for such refund would not cause such Person to suffer any material economic, legal or regulatory disadvantage. If any Lender or Agent receives a refund in respect of any Taxes or Other Taxes as to which indemnification or additional amounts have been paid to it by any Borrower pursuant to this Section 3.01, it shall promptly remit such refund (including any interest included in such refund) to such Borrower (to the extent that it determines that it can do so without prejudice to the retention of the refund), net of all reasonable out-of-pocket expenses of the Lender or Agent, as the case may be; provided that such Borrower, upon the request of the Lender or Agent, as the case may be, agrees promptly to return such refund to such party in the event such party is required to repay such refund to the relevant taxing authority. Such Lender or Agent, as the case may be, shall, at such Borrower’s request, provide such Borrower with a copy of any notice of assessment or other evidence of the requirement to repay such refund received from the relevant taxing authority (provided that such Lender or Agent may delete any information therein that such Lender or Agent deems confidential). Nothing herein contained shall interfere with the right of a Lender or Agent to arrange its tax affairs in whatever manner it thinks fit nor oblige any Lender or Agent to claim any tax refund or to disclose any information relating to its tax affairs or any computations in respect thereof or require any Lender or Agent to do anything that would prejudice its ability to benefit from any other refunds, credits, reliefs, remissions or repayments to which it may be entitled.

(g) Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 3.01(a) or Section 3.01(c) with respect to such Lender it will, if requested by the relevant Borrower, use commercially reasonable efforts (subject to such Lender’s overall internal policies of general application and legal and regulatory restrictions) to avoid the consequences of such event, including to designate another Lending Office for any Loan or Letter of Credit affected by such event; provided that such efforts are made on terms that, in the reasonable judgment of such Lender, cause such Lender and its Lending Office(s) to suffer no material economic, legal or regulatory disadvantage, and provided further that nothing in this Section 3.01(g) shall affect or postpone any of the Obligations of any Borrower or the rights of the Lender pursuant to Section 3.01(a) and Section 3.01(c).

SECTION 3.02. Illegality. If any Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund Eurodollar Rate Loans or to determine or charge interest rates based upon the Eurodollar Rate, then, on notice thereof by such Lender to the Borrowers through the Administrative Agent, any obligation of such Lender to make Eurodollar Rate Loans or continue Eurodollar Rate Loans or to convert Base Rate Loans to Eurodollar Rate Loans shall be suspended until such Lender notifies the Administrative Agent and the Borrowers that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, each such Borrower (i) may revoke any pending request for a Borrowing of, conversion to, or continuation of Eurodollar Rate Loans or (ii) shall, upon demand from such Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert all Eurodollar Rate Loans of such Lender to Base Rate Loans, either on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such Eurodollar Rate Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such Eurodollar Rate Loans. Upon any such prepayment or conversion, each such Borrower shall also pay accrued interest on the amount so prepaid or converted. Each Lender agrees to designate a different Lending Office if such designation will avoid the need for such notice and will not, in the good faith judgment of such Lender, otherwise be materially disadvantageous to such Lender.

SECTION 3.03. Inability to Determine Rates. If the Required Lenders determine that for any reason adequate and reasonable means do not exist for determining the Eurodollar Rate for any requested Interest Period with respect to a proposed Eurodollar Rate Loan or that the Eurodollar Rate for any requested Interest Period with respect to a proposed Eurodollar Rate Loan does not adequately and fairly reflect the cost to such Lenders of funding such Loan, or that Dollar deposits are not being offered to banks in the London interbank eurodollar market for the applicable amount and the Interest Period of such Eurodollar Rate Loan the Administrative Agent will promptly so notify each Borrower and each Lender. Thereafter, the obligation of the Lenders to make or maintain Eurodollar Rate Loans shall be suspended until the Administrative Agent (upon the instruction of the Required Lenders) revokes such notice. Upon receipt of such notice, each Borrower may revoke any pending request for a Borrowing of, conversion to or continuation of Eurodollar Rate Loans or, failing that, will be deemed to have converted such request into a request for a Borrowing of Base Rate Loans in the amount specified therein.

SECTION 3.04. Increased Cost and Reduced Return; Capital Adequacy; Reserves on Eurodollar Rate Loans. (a) If any Lender reasonably determines in good faith that as a result of the introduction of or any change in or in the interpretation of any Law, in each case after the date hereof, or such Lender’s compliance therewith, there shall be any increase in the cost to such Lender of agreeing to make or making, funding or maintaining Eurodollar Rate Loans or (as the case may be) issuing or participating in Letters of Credit, or a reduction in the amount received or receivable by such Lender in connection with any of the foregoing (excluding for purposes of this Section 3.04(a) any such increased costs or reduction in amount resulting from (i) taxes (as to which Section 3.01 shall govern), (ii) changes in the basis of taxation of overall net income or overall gross income (including branch profits), and franchise (and similar) taxes imposed in lieu of net income taxes, by the United States or any foreign

jurisdiction or any political subdivision of either thereof under the Laws of which such Lender is organized or maintains a Lending Office and (iii) reserve requirements contemplated by Section 3.04(c), then from time to time each such Borrower (A) may revoke any pending request for a Borrowing of Eurodollar Rate Loans conversion to or continuation of Eurodollar Rate Loans or (B) within thirty (30) days after written demand by such Lender setting forth in reasonable detail such increased costs or reduction (with a copy of such demand to the Administrative Agent given in accordance with Section 3.06), the relevant Borrower shall pay to such Lender such additional amounts as will compensate such Lender for such increased cost or reduction.

(b) If any Lender reasonably determines in good faith that the introduction of any Law regarding capital adequacy or any change therein or in the interpretation thereof, in each case after the date hereof, or compliance by such Lender (or its Lending Office) therewith, has the effect of reducing the rate of return on the capital of such Lender or any corporation controlling such Lender as a consequence of such Lender’s obligations hereunder (taking into consideration its policies with respect to capital adequacy and such Lender’s desired return on capital), then from time to time (i) each such Borrower may revoke any pending request for a Borrowing of, conversion to or continuation of Eurodollar Rate Loans, (ii) within thirty (30) days after written demand by such Lender setting forth in reasonable detail the charge and the calculation of such reduced rate of return (with a copy of such demand to the Administrative Agent given in accordance with Section 3.06), the relevant Borrower shall pay to such Lender such additional amounts as will compensate such Lender for such reduction.

(c) Each Borrower shall pay to each Lender, (i) as long as such Lender shall be required to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency funds or deposits (currently known as “Eurocurrency liabilities”), additional interest on the unpaid principal amount of each Eurodollar Rate Loan equal to the actual costs of such reserves allocated to such Loan by such Lender (as determined by such Lender in good faith, which determination shall be conclusive in the absence of manifest error), and (ii) as long as such Lender shall be required to comply with any reserve ratio requirement or analogous requirement of any other central banking or financial regulatory authority imposed in respect of the maintenance of the Revolving Credit Commitments or the funding of the Eurodollar Rate Loans such additional costs (expressed as a percentage per annum and rounded upwards, if necessary, to the nearest five decimal places) equal to the actual costs allocated to such Revolving Credit Commitment or Loan by such Lender (as determined by such Lender in good faith, which determination shall be conclusive absent manifest error) which in each case shall be due and payable on each date on which interest is payable on such Loan; provided such Borrower shall have received at least thirty (30) days’ prior notice (with a copy to the Administrative Agent) of such additional interest or cost from such Lender. If a Lender fails to give notice thirty (30) days prior to the relevant Interest Payment Date, such additional interest or cost shall be due and payable thirty (30) days from receipt of such notice.

(d) No Borrower shall be required to compensate a Lender pursuant to Section 3.04(a), Section 3.04(b) or Section 3.04(c) for any such increased cost or reduction incurred more than ninety (90) days prior to the date that such Lender demands, or notifies such Borrower of its intention to demand, compensation therefor; provided that, if the circumstance giving rise to such increased cost or reduction is retroactive, then such 90-day period referred to above shall be extended to include the period of retroactive effect thereof.

(e) If any Lender requests compensation under this Section 3.04, then such Lender will, if requested by the relevant Borrower, use commercially reasonable efforts to designate another Lending Office for any Loan or Letter of Credit affected by such event; provided that such efforts are made on terms that, in the reasonable judgment of such Lender, cause such Lender and its Lending Office(s) to suffer no material economic, legal or regulatory disadvantage, and provided further that nothing in this

Section 3.04(e) shall affect or postpone any of the Obligations of any Borrower or the rights of such Lender pursuant to Section 3.04(a), Section 3.04(b), Section 3.04(c) or Section 3.04(d).

SECTION 3.05. Funding Losses. Upon demand of any Lender from time to time, each Borrower shall promptly compensate such Lender for and hold such Lender harmless from any loss, cost or expense incurred by it as a result of:

(a) any continuation, conversion, payment or prepayment of any Loan other than a Base Rate Loan on a day other than the last day of the Interest Period for such Loan (whether voluntary, mandatory, automatic, by reason of acceleration, or otherwise); or

(b) any failure by any Borrower (for a reason other than the failure of such Lender to make a Loan) to prepay, borrow, continue or convert any Loan other than a Base Rate Loan on the date or in the amount notified by such Borrower;

including any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Loan or from fees payable to terminate the deposits from which such funds were obtained.

For purposes of calculating amounts payable by a Borrower to the Lenders under this Section 3.05, each Lender shall be deemed to have funded each Eurodollar Rate Loan made by it at the Eurodollar Rate for such Loan by a matching deposit or other borrowing in the London interbank eurodollar market for a comparable amount and for a comparable period, whether or not such Eurodollar Rate Loan was in fact so funded.

SECTION 3.06. Matters Applicable to Requests for Compensation. (a) Any Agent or any Lender claiming compensation under this Article 3 shall deliver a certificate to the applicable Borrower setting forth in reasonable detail the additional amount or amounts to be paid to it hereunder, which shall be conclusive in the absence of manifest error. In determining such amount, such Agent or such Lender may use any reasonable averaging and attribution methods.

(b) With respect to any Lender’s claim for compensation under Section 3.02, Section 3.03 or Section 3.04, no Borrower shall be required to compensate such Lender for any amount incurred more than ninety (90) days prior to the date that such Lender notifies the relevant Borrower of the event that gives rise to such claim; provided that, if the circumstance giving rise to such increased cost or reduction is retroactive, then such 90-day period referred to above shall be extended to include the period of retroactive effect thereof. If any Lender requests compensation by a Borrower under Section 3.04, such Borrower may, by notice to such Lender (with a copy to the Administrative Agent), suspend the obligation of such Lender to make or continue Eurodollar Rate Loans from one Interest Period to another, or to convert Base Rate Loans into Eurodollar Rate Loans, until the event or condition giving rise to such request ceases to be in effect (in which case the provisions of Section 3.06(c) shall be applicable); provided that such suspension shall not affect the right of such Lender to receive the compensation so requested.

(c) If the obligation of any Lender to make or continue any Eurodollar Rate Loan from one Interest Period to another, or to convert Base Rate Loans into Eurodollar Rate Loans shall be suspended pursuant to Section 3.06(b) hereof, such Lender’s Eurodollar Rate Loans shall be automatically converted into Base Rate Loans on the last day(s) of the then current Interest Period(s) for such Eurodollar Rate Loans (or, in the case of an immediate conversion required by Section 3.02, on such earlier date as required by Law) and, unless and until such Lender gives notice as provided below that the circumstances specified in Section 3.01, Section 3.02, Section 3.03 or Section 3.04 hereof that gave rise to such conversion no longer exist:

(i) to the extent that such Lender’s Eurodollar Rate Loans have been so converted, all payments and prepayments of principal that would otherwise be applied to such Lender’s Eurodollar Rate Loans shall be applied instead to its Base Rate Loans; and

(ii) all Loans that would otherwise be made or continued as Eurodollar Rate Loans from one Interest Period to another by such Lender shall be made or continued instead as Base Rate Loans, and all Base Rate Loans of such Lender that would otherwise be converted into Eurodollar Rate Loans shall remain as Base Rate Loans.

(d) If any Lender gives notice to a Borrower (with a copy to the Administrative Agent) that the circumstances specified in Section 3.01, Section 3.02, Section 3.03 or Section 3.04 hereof that gave rise to the conversion of such Lender’s Eurodollar Rate Loans pursuant to this Section 3.06 no longer exist (which such Lender agrees to do promptly upon such circumstances ceasing to exist) at a time when Eurodollar Rate Loans made by other Lenders are outstanding, such Lender’s Base Rate Loans shall be automatically converted irrespective of whether such conversion results in greater than twenty-five (25) Interest Periods being outstanding under this Agreement, on the first day(s) of the next succeeding Interest Period(s) for such outstanding Eurodollar Rate Loans, to the extent necessary so that, after giving effect thereto, all Loans held by the Lenders holding Eurodollar Rate Loans and by such Lender are held pro rata (as to principal amounts, interest rate basis, and Interest Periods) in accordance with their respective Revolving Credit Commitments.

SECTION 3.07. Replacement of Lenders Under Certain Circumstances. (a) If at any time (x) any Borrower becomes obligated to pay additional amounts or indemnity payments described in Section 3.01 or Section 3.04 as a result of any condition described in such Sections or any Lender ceases to make Eurodollar Rate Loans as a result of any condition described in Section 3.02 or Section 3.04, (y) any Lender becomes a Defaulting Lender or (z) any Lender becomes a Non Consenting Lender, then such Borrower may, on five (5) Business Days’ prior written notice to the Administrative Agent and such Lender, replace such Lender (in its capacity as a Lender under the applicable Facility, if the underlying matter in respect of which such Lender has become a Non-Consenting Lender relates to a certain Class of Loans or Revolving Credit Commitments) by causing such Lender to (and such Lender shall be obligated to) assign pursuant to Section 10.07(b) (with the assignment fee to be paid by such Borrower in such instance) all of its rights and obligations under this Agreement (in respect of the applicable Class of Loans or Revolving Credit Commitments if the underlying matter in respect of which such Lender has become a Non-Consenting Lender relates to a certain Class of Loans or Revolving Credit Commitments) to one or more Eligible Assignees; provided that (A) in the case of any Eligible Assignees in respect of Non-Consenting Lenders, the replacement Lender shall agree to the consent, waiver or amendment to which the Non-Consenting Lender did not agree and (B) neither the Administrative Agent nor any Lender shall have any obligation to any Borrower to find a replacement Lender or other such Person.

(b) Any Lender being replaced pursuant to Section 3.07(a) above shall (i) execute and deliver an Assignment and Assumption with respect to such Lender’s Revolving Credit Commitment and outstanding Loans of the applicable Class and, if applicable, participations in L/C Obligations and Swing Line Loans, and (ii) deliver any Notes evidencing such Loans to the relevant Borrower or the Administrative Agent. Pursuant to such Assignment and Assumption, (i) the assignee Lender shall acquire all or a portion, as the case may be, of the assigning Lender’s Revolving Credit Commitment and outstanding Loans of the applicable Class and, if applicable, participations in L/C Obligations and Swing Line Loans, (ii) all obligations of the Borrowers owing to the assigning Lender relating to the Loans and participations so assigned shall be paid in full by the assignee Lender to such assigning Lender concurrently with such assignment and assumption and (iii) upon such payment and, if so requested by the assignee Lender, delivery to the assignee Lender of the appropriate Note or Notes executed by the

relevant Borrower, the assignee Lender shall become a Lender hereunder and the assigning Lender shall cease to constitute a Lender hereunder with respect to such assigned Loans, Revolving Credit Commitments and participations, except with respect to indemnification provisions under this Agreement, which shall survive as to such assigning Lender.

(c) Notwithstanding anything to the contrary contained above, (i) the Lender that acts as the L/C Issuer may not be replaced hereunder at any time that it has any Letter of Credit outstanding hereunder unless arrangements reasonably satisfactory to such L/C Issuer (including the furnishing of a back-up standby letter of credit in form and substance, and issued by an issuer reasonably satisfactory to such L/C Issuer or the depositing of cash collateral into a cash collateral account in amounts and pursuant to arrangements reasonably satisfactory to such L/C Issuer) have been made with respect to such outstanding Letter of Credit and (ii) the Lender that acts as the Administrative Agent may not be replaced in such capacity hereunder except in accordance with the terms of Section 9.06.

(d) In the event that (i) the Borrowers or the Administrative Agent has requested the Lenders to consent to a departure or waiver of any provisions of the Loan Documents or to agree to any amendment thereto, (ii) the consent, waiver or amendment in question requires the agreement of all affected Lenders in accordance with the terms of Section 10.01 or all the Lenders with respect to a certain Class of Loans or Revolving Credit Commitments and (iii) the Required Lenders have agreed to such consent, waiver or amendment, then any Lender who does not agree to such consent, waiver or amendment shall be deemed a “Non-Consenting Lender.”

SECTION 3.08. Survival. All of the Borrowers’ obligations under this Article 3 shall survive termination of the Aggregate Commitments and repayment of all other Obligations hereunder.

(c) require that the Borrowers Cash Collateralize the L/C Obligations (in an amount equal to the then Outstanding Amount thereof); and

(d) exercise on behalf of itself and the Lenders all rights and remedies available to it and the Lenders under the Loan Documents or applicable Law;

Second, to the payment in full of the Unfunded Advances/Participations (the amounts so applied to be distributed between or among the Administrative Agent, the Swing Line Lender and any L/C Issuer pro rata in accordance with the amounts of Unfunded Advances/Participations owed to them on the date of any distribution);

Third, to payment of that portion of the Obligations constituting fees, indemnities and other amounts (other than principal and interest) payable to the Lenders and any L/C Issuer (including Attorney Costs payable under Section 10.05 and amounts payable under Article 3), ratably among them in proportion to the amounts described in this clause Third payable to them;

Fifth, ratably to (a) the Administrative Agent for the account of the L/C Issuer, to Cash Collateralize that portion of L/C Obligations comprised of the aggregate undrawn amount of Letters of Credit and (b) to payment of that portion of the Obligations constituting unpaid principal of the Loans, ratably among the Secured Parties in proportion to the respective amounts described in this clause Fifth held by them;

Sixth, to the payment of the Secured Hedge Obligations, the Cash Management Obligations and all other Obligations of the Loan Parties that are due and payable to the Administrative Agent and the other Secured Parties on such date, ratably based upon the respective aggregate amounts of all such Obligations owing to the Administrative Agent and the other Secured Parties on such date; and

Last, the balance, if any, after all of the Obligations (other than contingent indemnification obligations not then due and payable and Letters of Credit that are cash collateralized on terms reasonably satisfactory to the applicable L/C Issuer) have been paid in full, to the Borrowers or as otherwise required by Law.

Subject to Section 2.03(c), amounts used to Cash Collateralize the aggregate undrawn amount of Letters of Credit pursuant to clause Fifth (b) above shall be applied to satisfy drawings under such Letters of Credit as they occur. If any amount remains on deposit as Cash Collateral after all Letters of Credit have either been fully drawn or expired, such remaining amount shall be applied to the other Obligations, if any, in the order set forth above and, if no Obligations remain outstanding, delivered to the Borrowers.

ARTICLE 9

ADMINISTRATIVE AGENT AND OTHER AGENTS

SECTION 9.01. Authorization and Action. (a) Each Lender (in its capacities as a Lender, a Swing Line Lender (if applicable), an Issuing Bank (if applicable) and on behalf of itself and its Affiliates as potential Hedge Banks) hereby appoints and authorizes each Agent to take such action as agent on its behalf and to exercise such powers and discretion under this Agreement and the other Loan Documents as are delegated to such Agent by the terms hereof and thereof, together with such powers and discretion as are reasonably incidental thereto. As to any matters not expressly provided for by the Loan Documents (including, without limitation, enforcement or collection of the Loans), no Agent shall be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Required Lenders, and such instructions shall be binding upon all Lenders, all Hedge Banks and all holders of Notes; provided, however, that, whether or not expressly provided fro in this Agreement or the other Loan Documents, no Agent shall be required to take any action that exposes or which such Agent reasonably believes exposes such Agent to personal liability or that is contrary to this Agreement or applicable law. Each Agent agrees to give to each Lender prompt notice of each notice given to it by the Borrowers pursuant to the terms of this Agreement.

(b) In furtherance of the foregoing, each Lender (in its capacities as a Lender, a Swing Line Lender (if applicable), an Issuing Bank (if applicable) and on behalf of itself and its Affiliates as potential Hedge Banks) hereby appoints and authorizes the Collateral Agent to act as the agent of such Lender for purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any of the Loan Parties to secure any of the Secured Obligations, together with such powers and discretion as are reasonably incidental thereto. In this connection, the Collateral Agent (and any Supplemental Collateral Agents appointed by the Collateral Agent pursuant to Section 9.01(c) for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the Collateral Documents, or for exercising any rights or remedies thereunder at the direction of the Collateral Agent), shall be entitled to the benefits of this Article 9 (including, without limitation, Section 9.05 as though any such Supplemental Collateral Agents were an “Agent” under the Loan Documents) as if set forth in full herein with respect thereto.

(c) Any Agent may execute any of its duties under this Agreement or any other Loan Document (including for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the Collateral Documents or of exercising any rights and remedies thereunder at the direction of the Collateral Agent) by or through agents, employees or attorneys-in-fact and shall be entitled to advice of counsel and other consultants or experts concerning all matters pertaining to such duties. The Collateral Agent may also from time to time, when the Collateral Agent deems it to be necessary or desirable, appoint one or more trustees, co-trustees, collateral co-agents, collateral subagents or attorneys-in-fact (each, a “Supplemental Collateral Agent”) with respect to all or any part of the Collateral; provided, however, that no such Supplemental Collateral Agent shall be authorized to take any action with respect to any Collateral unless and except to the extent expressly authorized in writing by the Collateral Agent. Should any instrument in writing from the Borrowers or any other Loan Party be required by any Supplemental Collateral Agent so appointed by the Collateral Agent to more fully or certainly vest in and confirm to such Supplemental Collateral Agent such rights, powers, privileges and duties, the Borrowers shall, or shall cause such Loan Party to, execute, acknowledge and deliver any and all such instruments promptly upon request by the Collateral Agent. If any Supplemental Collateral Agent, or successor thereto, shall die, become incapable of acting, resign or be removed, all rights, powers, privileges and duties of such Supplemental Collateral Agent, to the extent permitted by law, shall automatically vest in and be exercised by the Collateral Agent until the appointment of a new

109

Supplemental Collateral Agent. No Agent shall be responsible for the negligence or misconduct of any agent, attorney-in-fact or Supplemental Collateral Agent that it selects in accordance with the foregoing provisions of this Section 9.01(c) in the absence of such Agent’s gross negligence, bad faith or willful misconduct.

SECTION 9.02. Agents’ Reliance, Etc. Neither any Agent nor any of their respective directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with the Loan Documents, except for its or their own gross negligence, bad faith or willful misconduct. Without limitation of the generality of the foregoing, each Agent: (a) may consult with legal counsel (including counsel for any Loan Party), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (b) makes no warranty or representation to any Lender and shall not be responsible to any Lender for any statements, warranties or representations (whether written or oral) made in or in connection with the Loan Documents; (c) shall not have any duty to ascertain or to inquire as to the performance, observance or satisfaction of any of the terms, covenants or conditions of any Loan Document on the part of any Loan Party or the existence at any time of any Default under the Loan Documents or to inspect the property (including the books and records) of any Loan Party; (d) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the perfection or priority of any lien or security interest created or purported to be created under or in connection with, any Loan Document or any other instrument or document furnished pursuant thereto; and (e) shall incur no liability under or in respect of any Loan Document by acting upon any notice, consent, certificate or other instrument or writing (which may be by telegram or telecopy) believed by it to be genuine and signed or sent by the proper party or parties.

SECTION 9.03. ▇▇▇▇▇▇▇ ▇▇▇▇▇ Capital, a division of ▇▇▇▇▇▇▇ ▇▇▇▇▇ Business Financial Services, Inc. and Affiliates. With respect to its Revolving Credit Commitments, the Loans made by it and any Notes issued to it, ML Capital shall have the same rights and powers under the Loan Documents as any other Lender and may exercise the same as though it was not an Agent; and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include ML Capital in its individual capacities. ML Capital and its affiliates may accept deposits from, lend money to, act as trustee under indentures of, accept investment banking engagements from and generally engage in any kind of business with, any Loan Party, any of its Subsidiaries and any Person that may do business with or own securities of any Loan Party or any such Subsidiary, all as if ML Capital was not an Agent and without any duty to account therefor to the Lenders. No Agent shall have any duty to disclose any information obtained or received by it or any of its Affiliates relating to any Loan Party or any of its Subsidiaries to the extent such information was obtained or received in any capacity other than as such Agent.

SECTION 9.04. Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon any Agent or any other Lender and based on the financial statements referred to in Section 5.01 and such other 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 any Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement.

SECTION 9.05. Indemnification. (a) Each Lender severally agrees to indemnify each Agent (to the extent not promptly reimbursed by the Borrowers) from and against such Lender’s ratable share (determined as provided below) of any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever

110

that may be imposed on, incurred by, or asserted against such Agent in any way relating to or arising out of the Loan Documents or any action taken or omitted by such Agent under the Loan Documents (collectively, the “Indemnified Costs”); provided, however, that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from such Agent’s gross negligence or willful misconduct as found in a final, non-appealable judgment by a court of competent jurisdiction. Without limitation of the foregoing, each Lender agrees to reimburse each Agent promptly upon demand for its ratable share of any costs and expenses (including, without limitation, reasonable fees and expenses of counsel) payable by the Borrowers under Section 10.04, to the extent that such Agent is not promptly reimbursed for such costs and expenses by the Borrowers. In the case of any investigation, litigation or proceeding giving rise to any Indemnified Costs, this Section 9.05 applies whether any such investigation, litigation or proceeding is brought by any Lender or any other Person.

(b) Each Lender severally agrees to indemnify the Issuing Bank (to the extent not promptly reimbursed by the Borrowers) from and against such Lender’s ratable share (determined as provided below) of any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Issuing Bank in any way relating to or arising out of the Letters of Credit or the Loan Documents or any action taken or omitted by the Issuing Bank under the Letters of Credit or the Loan Documents; provided, however, that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Issuing Bank’s gross negligence or willful misconduct as found in a final, non-appealable judgment by a court of competent jurisdiction. Without limitation of the foregoing, each Lender agrees to reimburse the Issuing Bank promptly upon demand for its ratable share of any costs and expenses (including, without limitation, reasonable fees and expenses of counsel) payable by the Borrowers under Section 9.04, to the extent that the Issuing Bank is not promptly reimbursed for such costs and expenses by the Borrowers.

(c) For purposes of this Section 9.05, each Lender’s respective ratable share of any amount shall be determined, at any time, according to the sum of (i) the aggregate principal amount of the Loans outstanding at such time and owing to such Lender, (ii) such Lender’s Pro Rata Share of the aggregate available amount of all Letters of Credit outstanding at such time, and (iii) such Lender’s unused Revolving Credit Commitments at such time; provided that the aggregate principal amount of Swing Line Loans owing to the Swing Line Lender and of Letter of Credit Loans owing to the Issuing Bank shall be considered to be owed to the Lenders ratably in accordance with their respective Revolving Credit Commitments. The failure of any Lender to reimburse any Agent or the Issuing Bank, as the case may be, promptly upon demand for its ratable share of any amount required to be paid by the Lenders to such Agent or the Issuing Bank, as the case may be, as provided herein shall not relieve any other Lender of its obligation hereunder to reimburse such Agent or the Issuing Bank, as the case may be, for its ratable share of such amount, but no Lender shall be responsible for the failure of any other Lender to reimburse such Agent or the Issuing Bank, as the case may be, for such other Lender’s ratable share of such amount. Without prejudice to the survival of any other agreement of any Lender hereunder, the agreement and obligations of each Lender contained in this Section 9.05 shall survive the payment in full of principal, interest and all other amounts payable hereunder and under the other Loan Documents.

SECTION 9.06. Successor Agents. Any Agent may resign as to any or all of the Facilities at any time by giving written notice thereof to the Lenders and the Borrowers and may be removed as to all of the Facilities at any time with or without cause by the Required Lenders; provided, however, that any removal of the Administrative Agent will not be effective until it or its Affiliate has also been replaced as Collateral Agent, Swing Line Lender and Issuing Bank and discharged from all of its obligations in respect thereof. Upon any such resignation or removal, the Required Lenders shall have

111

the right (with the consent of the Borrowers, so long as no Event of Default under Section 8.01(a) or (f) has occurred or is continuing) to appoint a successor Agent as to such of the Facilities as to which such Agent has resigned or been removed. If no successor Agent shall have been so appointed by the Required Lenders (or, so long as no Event of Default Section 8.01(a) or (f) has occurred or is continuing, consented to by the Borrowers), and shall have accepted such appointment, within 30 days after the retiring Agent’s giving of notice of resignation or the Required Lenders’ removal of the retiring Agent, then the retiring Agent may, on behalf of the Lenders, appoint a successor Agent, which shall be a commercial bank organized under the laws of the United States or of any State thereof and having a combined capital and surplus of at least $250,000,000. Upon the acceptance of any appointment as Agent hereunder by a successor Agent as to all of the Facilities and, in the case of a successor Collateral Agent, upon the execution and filing or recording of such financing statements, or amendments thereto, and such amendments or supplements to the Mortgages, and such other instruments or notices, as may be necessary or desirable, or as the Required Lenders may reasonably request, in order to continue the perfection of the Liens granted or purported to be granted by the Collateral Documents, such successor Agent shall succeed to and become vested with all the rights, powers, discretion, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations under the Loan Documents. Upon the acceptance of any appointment as Agent hereunder by a successor Agent as to less than all of the Facilities and, in the case of a successor Collateral Agent, upon the execution and filing or recording of such financing statements, or amendments thereto, and such amendments or supplements to the Mortgages, and such other instruments or notices, as may be reasonably necessary or desirable, or as the Required Lenders may request, in order to continue the perfection of the Liens granted or purported to be granted by the Collateral Documents, such successor Agent shall succeed to and become vested with all the rights, powers, discretion, privileges and duties of the retiring Agent as to such Facilities, other than with respect to funds transfers and other similar aspects of the administration of Borrowings under such Facilities, issuances of Letters of Credit (notwithstanding any resignation as Agent with respect to the Letter of Credit Facility) and payments by the Borrowers in respect of such Facilities, and the retiring Administrative Agent shall be discharged from its duties and obligations under this Agreement as to such Facilities, other than as aforesaid. If within 45 days after written notice is given of the retiring Agent’s resignation or removal under this Section 9.06 no successor Agent shall have been appointed and shall have accepted such appointment, then on such 45th day (a) the retiring Agent’s resignation or removal shall become effective, (b) the retiring Agent shall thereupon be discharged from its duties and obligations under the Loan Documents and (c) the Required Lenders shall thereafter perform all duties of the retiring Agent under the Loan Documents until such time, if any, as the Required Lenders appoint a successor Agent as provided above. After any retiring Agent’s resignation or removal hereunder as Agent as to any of the Facilities shall have become effective, the provisions of this Article 9 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent as to such Facilities under this Agreement.

SECTION 9.07. Other Agents; Arrangers and Managers. None of the Lenders or other Persons identified on the facing page or signature pages of this Agreement as a “syndication agent,” “documentation agent,” “bookrunner,” or “lead arranger” shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than to the extent expressly set forth herein and, in the case of such Lenders, those applicable to all Lenders as such. Without limiting the foregoing, none of the Lenders or other Persons so identified shall have or be deemed to have any fiduciary relationship with any Lender. Each Lender acknowledges that it has not relied, and will not rely, on any of the Lenders or other Persons so identified in deciding to enter into this Agreement or in taking or not taking action hereunder.

SECTION 9.08. Intercreditor Agreement. Each of the Lenders and each L/C Issuer hereby acknowledges that it has received and reviewed the Intercreditor Agreement and agrees to be bound by the terms thereof. Each Lender and L/C Issuer (and each Person that becomes a Lender or L/C Issuer hereunder pursuant to Section 10.07) hereby (a) acknowledges that ML Capital is acting under

112

the Intercreditor Agreement in its capacity as the Collateral Agent and ▇▇▇▇▇ Fargo Bank, National Association is acting under the Intercreditor Agreement in its capacity as the Second Lien Collateral Agent and (b) waives any conflict of interest, now contemplated or arising hereafter, in connection therewith and agrees not to assert against ML Capital any claims, causes of action, damages or liabilities of whatever kind or nature relating thereto. Each Lender and each L/C Issuer (and each Person that becomes a Lender or L/C Issuer hereunder pursuant to Section 10.07) hereby authorizes and directs ML Capital to enter into the Intercreditor Agreement on behalf of such Lender or L/C Issuer and agrees that ML Capital, in its capacity thereunder, may take such actions on its behalf as is contemplated by the terms of the Intercreditor Agreement.

Notwithstanding anything to the contrary herein, no Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or consent hereunder, except that the Revolving Credit Commitment of such Lender may not be increased or extended without the consent of such Lender (it being understood that any Revolving Credit Commitments or Loans held or deemed held by any Defaulting Lender shall be excluded from a vote of the Lenders hereunder requiring any consent of the Lenders).

Notwithstanding anything to the contrary contained in Section 10.01, in the event that the Borrowers request that this Agreement be modified or amended in a manner that would require the unanimous consent of all of the Lenders and such modification or amendment is agreed to by the Required Lenders, then with the consent of the Borrowers and the Required Lenders, the Borrowers and the Required Lenders shall be permitted to amend the Agreement without the consent of the Non-Consenting Lenders to provide for the termination of the Revolving Credit Commitment of each Non-Consenting Lender at the election of the Borrowers and the Required Lenders, (b) the addition to this Agreement of one or more other financial institutions (each of which shall be an Eligible Assignee), or an increase in the Revolving Credit Commitment of one or more of the Required Lenders (with the written consent thereof), so that the total Revolving Credit Commitment after giving effect to such amendment shall be in the same amount as the total Revolving Credit Commitment immediately before giving effect to such amendment, (c) if any Loans are outstanding at the time of such amendment, the making of such additional Loans by such new financial institutions or Required Lender or Lenders, as the case may be, as may be necessary to repay in full with accrued interest and fees, at par, the outstanding Loans of the Non-Consenting Lenders immediately before giving effect to such amendment and (d) such other modifications to this Agreement as may be appropriate to effect the foregoing clauses (a), (b) and (c).

Further, notwithstanding anything to the contrary contained in Section 10.01, if within thirty (30) days following the Closing Date, the Administrative Agent and the Borrowers shall have jointly identified an obvious error or any error or omission of a technical or immaterial nature, in each case, in any provision of the Loan Documents, then the Administrative Agent and the Borrowers shall be permitted to

114

amend such provision and such amendment shall become effective without any further action or consent of any other party to any Loan Document if the same is not objected to in writing by the Required Lenders within five (5) Business Days following receipt of notice thereof.

SECTION 10.02. Notices and Other Communications; Facsimile Copies. (a) General. Unless otherwise expressly provided herein, all notices and other communications provided for hereunder or any other Loan Document shall be in writing (including by facsimile transmission). All such written notices shall be mailed, faxed or delivered to the applicable address, facsimile number or (subject to Section 10.02(c)) electronic mail address, and all notices and other communications expressly permitted hereunder to be given by telephone shall be made to the applicable telephone number, as follows:

(i) if to any Borrower, any Guarantor, the Administrative Agent, the L/C Issuer or the Swing Line Lender, to the address, facsimile number, electronic mail address or telephone number specified for such Person on Schedule 10.02 or to such other address, facsimile number, electronic mail address or telephone number as shall be designated by such party in a notice to the other parties; and

(ii) if to any other Lender, to the address, facsimile number, electronic mail address or telephone number specified in its Administrative Questionnaire or to such other address, facsimile number, electronic mail address or telephone number as shall be designated by such party in a notice to the relevant Borrower, the Administrative Agent, the L/C Issuer and the Swing Line Lender.

All such notices and other communications shall be deemed to be given or made upon the earlier to occur of (i) actual receipt by the relevant party hereto and (ii) (A) if delivered by hand or by courier, when signed for by or on behalf of the relevant party hereto; (B) if delivered by mail, four (4) Business Days after deposit in the mails, postage prepaid; (C) if delivered by facsimile, when sent and receipt has been confirmed; and (D) if delivered by electronic mail (which form of delivery is subject to the provisions of Section 10.02(c)), when delivered; provided that notices and other communications to the Administrative Agent, the L/C Issuer and the Swing Line Lender pursuant to Article 2 shall not be effective until actually received by such Person. In no event shall a voice mail message be effective as a notice, communication or confirmation hereunder.

(b) Effectiveness of Facsimile Documents and Signatures. Loan Documents may be transmitted and/or signed by facsimile. The effectiveness of any such documents and signatures shall, subject to applicable Law, have the same force and effect as manually signed originals and shall be binding on all Loan Parties, the Agents and the Lenders. The Administrative Agent may also require that any such documents and signatures be confirmed by a manually signed original thereof; provided that the failure to request or deliver the same shall not limit the effectiveness of any facsimile document or signature.

(c) Reliance by Agents and Lenders. The Administrative Agent and the Lenders shall be entitled to rely and act upon any notices (including telephonic Committed Loan Notices and Swing Line Loan Notices) purportedly given by or on behalf of any Borrower even if (i) such notices were not made in a manner specified herein, were incomplete or were not preceded or followed by any other form of notice specified herein, or (ii) the terms thereof, as understood by the recipient, varied from any confirmation thereof. The Borrowers shall indemnify each Agent-Related Person and each Lender from all actual losses, costs, expenses and liabilities resulting from the reliance by such Person on each notice purportedly given by or on behalf of any Borrower in the absence of gross negligence, bad faith or willful misconduct.

115

SECTION 10.03. No Waiver; Cumulative Remedies. No failure by any Lender or the Administrative Agent to exercise, and no delay by any such Person in exercising, any right, remedy, power or privilege hereunder or under any other Loan Document shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges herein provided, and provided under each other Loan Document, are cumulative and not exclusive of any rights, remedies, powers and privileges provided by Law.

SECTION 10.04. Attorney Costs, Expenses and Taxes. The Borrowers agree upon and following the Closing Date (a) to pay or reimburse the Administrative Agent for all reasonable out-of-pocket costs and expenses incurred in connection with the preparation, negotiation, syndication and execution of this Agreement and the other Loan Documents, and any amendment, waiver, consent or other modification of the provisions hereof and thereof, and the consummation and administration of the transactions contemplated hereby and thereby, including all Attorney Costs of one attorney for all Lenders and the Administrative Agent (which shall be Shearman & Sterling LLP) and such other local counsel in each foreign jurisdiction as agreed between the Administrative Agent and the Borrowers, and (b) to pay or reimburse the Administrative Agent and each Lender for all reasonable out-of-pocket costs and expenses incurred in connection with the enforcement of any rights or remedies under this Agreement or the other Loan Documents (including all such costs and expenses incurred during any legal proceeding, including any proceeding under any Debtor Relief Law), including all Attorney Costs of counsel (which counsel shall be limited as provided in Section 10.05). The foregoing costs and expenses shall include all reasonable search, filing, recording, title insurance and appraisal charges and fees and taxes related thereto, and other reasonable out-of-pocket expenses incurred by any Agent. All amounts due under this Section 10.04 shall be paid promptly (but in any event within 30 days) following receipt by the Borrowers of an invoice relating thereto setting forth such expenses in reasonable detail. The agreements in this Section 10.04 shall survive the termination of the Aggregate Commitments and repayment of all other Obligations. If any Loan Party fails to pay when due any costs, expenses or other amounts payable by it hereunder or under any Loan Document, such amount may be paid on behalf of such Loan Party by the Administrative Agent or any Lender, in its sole discretion.

SECTION 10.05. Indemnification by the Borrowers. The Borrowers shall indemnify and hold harmless each Agent-Related Person, each Lender, each L/C Issuer and their respective Affiliates, directors, officers, employees, counsel, agents, attorneys-in-fact, trustees and advisors (collectively the “Indemnitees”) from and against any and all liabilities, obligations, actual losses, actual damages, penalties, claims, demands, actions, judgments, suits, reasonable costs, reasonable expenses and reasonable disbursements (including Attorney Costs (which shall be limited to one (1) counsel to the Administrative Agent and the Lenders (exclusive of one local counsel to the Administrative Agent and the Lenders in each appropriate jurisdiction), unless (x) the interests of the Administrative Agent and the Lenders are sufficiently divergent, in which case one (1) additional counsel may be appointed and (y) if the interests of any Lender or group of Lenders (other than all of the Lenders) are distinctly or disproportionately affected, one (1) additional counsel for such Lender or group of Lenders in the case of clause (a) below)) of any kind or nature whatsoever which may at any time be imposed on, incurred by or asserted against any such Indemnitee in any way relating to or arising out of or in connection with (a) the execution, delivery, enforcement, performance or administration of any Loan Document or any other agreement, letter or instrument delivered in connection with the transactions contemplated thereby or the consummation of the transactions contemplated thereby, (b) any Revolving Credit Commitment, Loan or Letter of Credit or the use or proposed use of the proceeds therefrom (including any refusal by the L/C Issuer 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), or (c) any actual or alleged presence or release of Hazardous Materials on or from any property currently or formerly owned or operated by any Borrower, any Subsidiary or any other Loan Party, or any

116

Environmental Liability related in any way to any Borrower, any Subsidiary or any other Loan Party, or (d) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory (including any investigation of, preparation for, or defense of any pending or threatened claim, investigation, litigation or proceeding) and regardless of whether any Indemnitee is a party thereto (and regardless of whether such matter is instituted by a third party or by any Borrower or any other Loan Party) (all the foregoing, collectively, the “Indemnified Liabilities”), in all cases, whether or not caused by or arising, in whole or in part, out of the negligence of the Indemnitee; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such liabilities, obligations, losses, damages, penalties, claims, demands, actions, judgments, suits, costs, expenses or disbursements (x) have been determined in the final judgment of a court of competent jurisdiction to have resulted from the gross negligence, bad faith or willful misconduct of any Indemnitee or any of its directors, officers or employees or a material breach of the Loan Documents by any Indemnitee or (y) arise from claims of any of the Lenders solely against one or more Lenders (and not by one or more Lenders against the Administrative Agent or one or more of the other Agents) that have not resulted from the action, inaction, participation or contribution of any Borrower or their respective Subsidiaries or other Affiliates or any of their respective officers, directors, stockholders, partners, members, employees, agents, representatives or advisors. No Indemnitee shall be liable for any damages arising from the use by others of any information or other materials obtained through IntraLinks or other similar information transmission systems in connection with this Agreement, nor shall any Indemnitee or any Loan Party have any liability for any special, punitive, indirect or consequential damages relating to this Agreement or any other Loan Document or arising out of its activities in connection herewith or therewith (whether before or after the Closing Date). In the case of an investigation, litigation or other proceeding to which the indemnity in this Section 10.05 applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by any Loan Party, its directors, shareholders or creditors or an Indemnitee or any other Person, whether or not any Indemnitee is otherwise a party thereto and whether or not any of the transactions contemplated hereunder or under any of the other Loan Documents is consummated. All amounts due under this Section 10.05 shall be paid promptly (but in any event within thirty (30) days) after written demand therefor; provided, however, that such Indemnitee shall promptly refund such amount to the extent that there is a final judicial or arbitral determination that such Indemnitee was not entitled to indemnification or contribution rights with respect to such payment pursuant to the express terms of this Section 10.05. The agreements in this Section 10.05 shall survive the resignation of the Administrative Agent, the replacement of any Lender, the termination of the Aggregate Commitments and the repayment, satisfaction or discharge of all the other Obligations.

SECTION 10.06. Payments Set Aside. To the extent that any payment by or on behalf of any Borrower is made to any Agent or any Lender, or any Agent or any Lender exercises its right of setoff, and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by such Agent or such Lender in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any Debtor Relief Law or otherwise, then (a) to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not occurred, and (b) each Lender severally agrees to pay to the Administrative Agent upon demand its applicable share of any amount so recovered from or repaid by any Agent, plus interest thereon from the date of such demand to the date such payment is made at a rate per annum equal to the applicable Federal Funds Rate from time to time in effect.

SECTION 10.07. 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, except that no Borrower may assign or otherwise transfer any of its rights or

117

obligations hereunder without the prior written consent of each Lender and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of Section 10.07(b), (ii) by way of participation in accordance with the provisions of Section 10.07(d), (iii) by way of pledge or assignment of a security interest subject to the restrictions of Section 10.07(f) or Section 10.07(h), as the case may be, or (iv) to an SPC in accordance with the provisions of Section 10.07(g) (and any other attempted assignment or transfer by any party hereto shall be null and void). 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, Participants to the extent provided in Section 10.07(d) and, to the extent expressly contemplated hereby, the Indemnitees) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Any Lender may at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Revolving Credit Commitment and the Loans (including for purposes of this Section 10.07(b), participations in L/C Obligations and in Swing Line Loans) at the time owing to it); provided that (i) except in the case of an assignment of the entire remaining amount of the assigning Lender’s Revolving Credit Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, the aggregate amount of the Revolving Credit Commitment (which for this purpose includes Loans outstanding thereunder) or, if the applicable Revolving Credit Commitment is not then in effect, the outstanding principal balance of the Loan 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 $1,000,000, in the case of any assignment in respect of the Revolving Credit Facility; (ii) except in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund (but subject to clause (iv) below), each of the Administrative Agent and, so long as no Event of Default in respect of Section 8.01(a), Section 8.01(f) or Section 8.01(g)(i) has occurred and is continuing and except for assignments in connection with the exchange of Lenders’ interests pursuant to arrangements relating thereto among the Lenders following the date on which either any Event of Default referred to in Section 8.01(f) or Section 8.01(g)(i) shall have occurred and be continuing in respect of any Borrower or the Loans shall have been declared immediately due and payable pursuant to Section 8.02, each Borrower consents to such assignment (each such consent not to be unreasonably withheld or delayed); (iii) any assignment must be approved by the Administrative Agent, the L/C Issuer and the Swing Line Lender (each such consent not to be unreasonably withheld or delayed); (v) the parties (other than the relevant Borrower unless its consent to such assignment is required hereunder) to each assignment shall (A) execute and deliver to the Administrative Agent an Assignment and Assumption via an electronic settlement system acceptable to the Administrative Agent (which initially may be ClearPar, LLC) or (B) manually execute and deliver to the Administrative Agent an Assignment and Assumption; and (vi) the assigning Lender shall deliver any Notes evidencing such Loans to the relevant Borrower or the Administrative Agent. Subject to acceptance and recording thereof by the Administrative Agent pursuant to Section 10.07(c), from and after the effective date specified in each Assignment and Assumption, the Eligible Assignee thereunder shall be a party to this Agreement 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 Section 3.01, Section 3.04, Section 3.05, Section 10.04 and Section 10.05 with respect to facts and circumstances occurring prior to the effective date of such assignment). Upon request, and the surrender by the assigning Lender of its Note, the relevant Borrower (at its expense) shall execute and deliver a Note to the assignee Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this clause (b) shall be

118

treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 10.07(d).

(c) The Administrative Agent, acting solely for this purpose as an agent of the Borrowers, shall maintain at the Administrative Agent’s Office 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 Revolving Credit Commitments of, and principal amounts (and related interest amounts) of the Loans, L/C Obligations (specifying the Unreimbursed Amounts), L/C Borrowings and amounts due under Section 2.03, owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, absent manifest error, and the Borrowers, the Agents and the Lenders shall 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 any Borrower, any Agent and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(d) Any Lender may at any time, without the consent of, or notice to, any Borrower or the Administrative Agent, sell participations to any Person (other than a natural person) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Revolving Credit Commitment and/or the Loans (including such Lender’s participations in L/C Obligations and/or Swing Line Loans) owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrowers, the Agents 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 the other Loan Documents and to approve any amendment, modification or waiver of any provision of this Agreement or the other Loan Documents; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, waiver or other modification described in the first proviso to Section 10.01 that directly affects such Participant. Subject to Section 10.07(e), the Borrowers agree that each Participant shall be entitled to the benefits of Section 3.01, Section 3.04 and Section 3.05 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 10.07(b) and such Participant agrees to be bound by such Sections and Section 3.06. To the extent permitted by Law, each Participant also shall be entitled to the benefits of Section 10.09 as though it were a Lender; provided that such Participant agrees to be subject to Section 2.13 as though it were a Lender.

(e) A Participant shall not be entitled to receive any greater payment under Section 3.01, Section 3.04 or Section 3.05 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 relevant Borrower’s prior written consent and such Participant complies with Section 3.01, Section 3.06 and Section 10.15 as if such Participant were a Lender under Section 10.15. A Participant shall not be entitled to the benefits of Section 3.01 unless the relevant Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the relevant Borrower, to comply with Section 3.01, Section 3.06 and Section 10.15 as though it were a Lender.

(f) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement (including under its Note, if any) to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

119

(g) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the relevant Borrower (an “SPC”) the option to provide all or any part of any Loan that such Granting Lender would otherwise be obligated to make pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to fund any Loan, and (ii) if an SPC elects not to exercise such option or otherwise fails to make all or any part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof. Each party hereto hereby agrees that (i) neither the grant to any SPC nor the exercise by any SPC of such option shall increase the costs or expenses or otherwise increase or change the obligations of the relevant Borrower under this Agreement (including its obligations under Section 3.01, Section 3.04 or Section 3.05), (ii) no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Lender would be liable, and (iii) the Granting Lender shall for all purposes, including the approval of any amendment, waiver or other modification of any provision of any Loan Document, remain the lender of record hereunder. The making of a Loan by an SPC hereunder shall utilize the Revolving Credit Commitment of the Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender. Notwithstanding anything to the contrary contained herein, any SPC may (i) with notice to, but without prior consent of the relevant Borrower and the Administrative Agent, assign all or any portion of its right to receive payment with respect to any Loan to the Granting Lender and (ii) disclose on a confidential basis any non-public information relating to its funding of Loans to any rating agency, commercial paper dealer or provider of any surety or Guarantee or credit or liquidity enhancement to such SPC.

(h) Notwithstanding anything to the contrary contained herein, any Lender that is a Fund may, without the consent of or notice to the Administrative Agent or any Borrower, create a security interest in all or any portion of the Loans owing to it and the Note, if any, held by it to the trustee for holders of obligations owed, or securities issued, by such Fund as security for such obligations or securities; provided that unless and until such trustee actually becomes a Lender in compliance with the other provisions of this Section 10.07, (i) no such pledge shall release the pledging Lender from any of its obligations under the Loan Documents and, (ii) such trustee shall not be entitled to exercise any of the rights of a Lender under the Loan Documents even though such trustee may have acquired ownership rights with respect to the pledged interest through foreclosure or otherwise (unless such trustee is an Eligible Assignee which has complied with the requirements of Section 10.07(b)).

(i) Notwithstanding anything to the contrary contained herein, any L/C Issuer or the Swing Line Lender may, upon thirty (30) days’ notice to the Borrowers and the Lenders, resign as a L/C Issuer and/or the Swing Line Lender; provided that on or prior to the expiration of such 30-day period with respect to such L/C Issuer’s resignation as a L/C Issuer, such L/C Issuer shall have identified a successor L/C Issuer reasonably acceptable to the Borrowers willing to accept its appointment as a successor L/C Issuer. In the event of any such resignation as a L/C Issuer or the Swing Line Lender, the Borrowers shall be entitled to appoint from among the Lenders willing to accept such appointment a successor L/C Issuer or Swing Line Lender hereunder; provided that no failure by the Borrowers to appoint any such successor shall affect the resignation of such L/C Issuer as a L/C Issuer or the Swing Line Lender, as the case may be, except as expressly provided above. If any L/C Issuer resigns as a L/C Issuer, it shall retain all the rights and obligations of a L/C Issuer hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as a L/C Issuer and all L/C Obligations with respect thereto (including the right to require the Lenders to make Base Rate Loans or fund risk participations in Unreimbursed Amounts pursuant to Section 2.03(c)). If the Swing Line Lender resigns as Swing Line Lender, it shall retain all the rights of the Swing Line Lender provided for hereunder with respect to Swing Line Loans made by it and outstanding as of the effective date of such resignation, including the right to require the Lenders to make Base Rate Loans or fund risk participations in outstanding Swing Line Loans pursuant to Section 2.04(c).

120

SECTION 10.08. Confidentiality. Each of the Agents and the Lenders agrees to maintain the confidentiality of the Information, except that Information may be disclosed (a) to it and its Affiliates’ directors, officers, employees, trustees and agents, including accountants, legal counsel 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 in accordance with this Section 10.08); (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; (provided that the Agent or Lender that discloses any Information pursuant to this clause (c) shall provide the Loan Parties prompt notice of such disclosure to the extent permitted by applicable Law so that such Loan Parties may seek an appropriate protective order or other appropriate remedy); (d) to any other party to this Agreement; (e) subject to an agreement containing provisions no less restrictive than those of this Section 10.08 (or as may otherwise be reasonably acceptable to the Loan Parties), to any Eligible Assignee of or Participant in, or any prospective Eligible Assignee of or Participant in, any of its rights or obligations under this Agreement; (f) with the specific prior written consent of the Responsible Officers of the applicable Loan Party; (g) to the extent such Information becomes publicly available other than as a result of a breach of this Section 10.08; (h) to any state, Federal or foreign authority or examiner (including the National Association of Insurance Commissioners or any other similar organization) regulating any Lender; (i) to any rating agency when required by it (it being understood that, prior to any such disclosure, such rating agency shall undertake to preserve the confidentiality of any Information relating to the Loan Parties received by it from such Lender in accordance herewith); (j) in connection with the exercise of any remedies hereunder or under any other Loan Document or any action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder to the extent reasonably necessary in connection with such enforcement or (k) to any direct or indirect contractual counterparty in swap agreements or such contractual counterparty’s professional advisor (so long as such contractual counterparty or professional advisor to such contractual counterparty agrees to be bound by the provisions of this Section 10.08). In addition, the Agents and the Lenders may disclose the existence of this Agreement and information about this Agreement to market data collectors, similar service providers to the lending industry, and service providers to the Agents and the Lenders in connection with the administration and management of this Agreement, the other Loan Documents, the Revolving Credit Commitments, and the Credit Extensions. For the purposes of this Section 10.08, “Information” means all information received from any Loan Party relating to any Loan Party or its business, other than any such information that is publicly available to any Agent or any Lender on a non-confidential basis prior to disclosure by any Loan Party other than as a result of a breach of this Section 10.08.

SECTION 10.09. Setoff. In addition to any rights and remedies of the Lenders provided by Law, upon the occurrence and during the continuance of any Event of Default, after obtaining the prior written consent of the Administrative Agent, each Lender is authorized at any time and from time to time, without prior notice to the Borrowers or any other Loan Party, any such notice being waived by each of the Borrowers (on its own behalf and on behalf of each Loan Party) 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 by, and other Indebtedness at any time owing by, such Lender to or for the credit or the account of the respective Loan Parties against any and all Obligations owing to such Lender hereunder or under any other Loan Document, now or hereafter existing, irrespective of whether or not such Agent or such Lender shall have made demand under this Agreement or any other Loan Document and although such Obligations may be contingent or unmatured. Each Lender agrees promptly to notify the Borrowers and the Administrative Agent after any such set off and application made by such Lender; provided that the failure to give such notice shall not affect the validity of such setoff and application. The rights of the Administrative Agent and each Lender under this Section 10.09 are in addition to other rights and remedies (including, without limitation, other rights of setoff) that the Administrative Agent and such Lender may have.

121

SECTION 10.10. Interest Rate Limitation. Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by applicable Law (the “Maximum Rate”). If any Agent or any Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such unpaid principal, refunded to the Borrowers. In determining whether the interest contracted for, charged, or received by an Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by applicable Law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Obligations hereunder.

SECTION 10.11. Counterparts. This Agreement and each other Loan Document may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Delivery by telecopier or “pdf” of an executed counterpart of a signature page to this Agreement and each other Loan Document shall be effective as delivery of an original executed counterpart of this Agreement and such other Loan Document.

(ii) Each Non-US Lender, to the extent it does not act or ceases to act for its own account with respect to any portion of any sums paid or payable to such Non-US Lender under any of the Loan Documents (for example, in the case of a typical participation by such Non-US Lender), shall deliver to the Borrowers and the Administrative Agent on the date when such Non-US Lender ceases to act for its own account with respect to any portion of any such sums paid or payable, and at such other times as may be necessary in the determination of the Borrowers or the Administrative Agent (in either case, in the reasonable exercise of its discretion), (A) two duly signed, properly completed copies of the forms or statements required to be provided by such Non-US Lender as set forth above, to establish the portion of any such sums paid or payable with respect to which such Non-US Lender acts for its own account that is not subject to United States withholding tax, and (B) two duly signed, properly completed copies of IRS Form W-8IMY (or any successor thereto), together with any information such Non-US Lender chooses to transmit with such form, and any other certificate or statement of exemption required under the Code, to establish that such Non-US Lender is not acting for its own account with respect to a portion of any such sums payable to such Non-US Lender.

(iii) If any form or document referred to in this Section 10.15 requires the disclosure of information, other than information necessary to compute the tax payable and information required on the date hereof by Internal Revenue Service, that the applicable Non-US Lender reasonably considers to be confidential, such Lender shall give notice thereof to the Borrowers and shall not be obligated to include in such form or document such confidential information.

123

(iv) The Borrowers shall not be required to pay any additional amount or any indemnity payment under Section 3.01 to (A) any Non-US Lender with respect to any Taxes required to be deducted or withheld on the basis of the information, certificates or statements of exemption such Lender transmits pursuant to this Section 10.15(a), or (B) any Non-US Lender with respect to any Taxes required to the deducted or withheld by reason of such Non-US Lender’s failure to satisfy the foregoing provisions of this Section 10.15(a), with respect to Taxes required to be deducted or withheld by reason of such US Lender’s failure; provided that if such Lender shall have satisfied the requirement of this Section 10.15(a) on the date such Lender became a Lender to the Borrowers or ceased to act for its own account with respect to any payment under any of the Loan Documents, nothing in this Section 10.15(a) shall relieve the Borrowers of their obligation to pay any amounts pursuant to Section 3.01 if such Lender’s failure to satisfy the provisions of Section 10.15(a) is reasonably the result of any change in any applicable Law, treaty or governmental rule, regulation or order, or any change in the interpretation, administration or application thereof.

(v) The Administrative Agent may deduct and withhold any taxes required by any Laws to be deducted and withheld from any payment under any of the Loan Documents.
