Loans may be Base Rate Loans or Eurodollar Rate Loans, as further provided herein.

2.02 Borrowings, Conversions and Continuations of Loans.

(a) Each Borrowing, each conversion of Loans from one Type to the other, and each continuation of Eurodollar Rate Loans shall be made upon a Borrower’s irrevocable notice to the Administrative Agent, which may be given by telephone. Each such notice must be received by the Administrative Agent not later than 10:00 a.m. (i) three Business Days prior to the requested date of any Borrowing of, conversion to or continuation of Eurodollar Rate Loans or of any conversion of Eurodollar Rate Loans to Base Rate Loans and (ii) on the requested date of any Borrowing of Base Rate Loans. Each telephonic notice by the applicable Borrower pursuant to this Section 2.02(a) must be confirmed promptly by delivery to the Administrative Agent of a written 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 principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof. Except as provided in Section 2.03(c) and Section 2.04(c), each Borrowing of or conversion to Base Rate Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof.

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 applicable Borrower requests a Borrowing of, conversion to, or continuation of Eurodollar Rate Loans in any such Loan Notice, but fails to specify an Interest Period, such Borrower will be deemed to have specified an Interest Period of one month.

(b) Following receipt of a Loan Notice, the Administrative Agent shall promptly notify each Lender of the amount of its Applicable Percentage of the applicable Loans, and if no timely notice of a conversion or continuation is provided by the applicable Borrower, the Administrative Agent shall notify each Lender of the details of any automatic conversion to Base Rate Loans described in Section 2.02(a). In the case of a Borrowing, each Lender shall, through its applicable Lending Office, make the amount of its Loan available to the Administrative Agent in immediately available funds at the Administrative Agent’s Office not later than 1:00 p.m. on the Business Day specified in the applicable Loan Notice. Upon satisfaction of the applicable conditions set forth in Section 4.02 (and, if such Borrowing is the initial Credit Extension, Section 4.01), the Administrative Agent shall make all funds so received available to the applicable Borrower in like funds as received by the Administrative Agent either by (i) crediting an account of such Borrower on the books of Bank of America with the amount of such funds or (ii) wire transfer of such funds, in each case in accordance with instructions provided to (and reasonably acceptable to) the Administrative Agent by the applicable Borrower; provided, however, that if, on the date the Loan Notice with respect to such Borrowing is given by the applicable Borrower, there are L/C Borrowings outstanding pertaining to such Borrower, then the proceeds of the Borrowing shall be applied, first, to the payment in full of any such L/C Borrowings, and second, shall be made available to such Borrower as provided above.

(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. During the existence of any Event of Default under Sections 8.01(a), 8.01(f) or 8.01(g) (or, upon notice from the Administrative Agent to the Borrowers at the request of the Required Lenders, any other Event of Default), no Loans may be requested as, converted to or continued as Eurodollar Rate Loans.

(d) The Administrative Agent shall promptly notify the applicable Borrower and the Lenders of the interest rate applicable to any Interest Period for Eurodollar Rate Loans upon determination of such interest rate. At any time that Base Rate Loans are outstanding, the Administrative Agent shall notify the applicable Borrower and the Lenders of any change in Bank of America’s prime rate used in determining the Base Rate promptly following the public announcement of such change.

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

(f) The failure of any Lender to make any 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 any Loan to be made by such other Lender on the date of any Borrowing.

(B) the issuance of such Letter of Credit would violate one or more policies of the L/C Issuer, which are generally applicable to Letters of Credit issued by such L/C Issuer;

(C) except as otherwise agreed by the Administrative Agent and the L/C Issuer, such Letter of Credit is in an initial stated amount less than $100,000;

(D) such Letter of Credit is denominated in a currency other than Dollars;

(E) such Letter of Credit contains any provisions for automatic reinstatement of the stated amount after any drawing thereunder; or

(F) a default of any Lender’s obligations to fund under Section 2.03(c) exists or any Lender is at such time a Defaulting Lender hereunder, unless the L/C Issuer has entered into satisfactory arrangements with the Borrowers to eliminate the L/C Issuer’s risk with respect to such Lender.

(iv) The L/C Issuer shall not amend any Letter of Credit if the L/C Issuer would not be permitted at the time of such amendment to issue such Letter of Credit in its amended form under the terms hereof.

(v) 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.

(vi) The L/C Issuer shall act on behalf of the Lenders with respect to any Letters of Credit issued by it and the documents associated therewith, and the L/C Issuer shall have all of the benefits and immunities (A) provided to the Administrative Agent in ARTICLE IX with respect to any acts taken or omissions suffered by the L/C Issuer in connection with Letters of Credit issued by it or proposed to be issued by it and Issuer Documents pertaining to such Letters of Credit as fully as if the term “Administrative Agent” as used in ARTICLE IX included the L/C Issuer with respect to such acts or omissions, and (B) as additionally provided herein with respect to the L/C Issuer.

(b) Procedures for Issuance and Amendment of Letters of Credit.

(i) Each Letter of Credit shall be issued or amended, as the case may be, upon the request of the applicable 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 the applicable Borrower. Such Letter of Credit Application must be received by the L/C Issuer and the Administrative Agent not later than 11:00 a.m. at least one Business Day prior to the proposed issuance date or date of amendment, as the case may be. 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 the following: (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 require. 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 the following: (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 require. Additionally, the applicable Borrower shall furnish to the L/C Issuer and the Administrative Agent such other documents and information pertaining to such requested Letter of Credit issuance or amendment, including any Issuer Documents, as the L/C Issuer or the Administrative Agent may reasonably require.

(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 applicable Borrower and, if not, the L/C Issuer will provide the Administrative Agent with a copy thereof. Unless the L/C Issuer has received written notice from any Lender, the Administrative Agent or either Borrower, at least one Business Day prior to the requested date of issuance or amendment of the applicable Letter of Credit, that one or more of the applicable conditions contained in ARTICLE IV shall not then be satisfied, 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 applicable Borrower or enter into the applicable amendment, as the case may be, in each case in accordance with the L/C Issuer’s usual and customary business practices. 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 a risk participation in such Letter of Credit in an amount equal to the product of such Lender’s Applicable Percentage times the amount of such Letter of Credit.

(iii) 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 applicable Borrower and the Administrative Agent a true and complete copy of such Letter of Credit or amendment.

(iv) If a Borrower so requests in any applicable Letter of Credit Application, the L/C Issuer shall, subject to the other terms and conditions hereof, issue a Letter of Credit that has automatic extension provisions (each, an “Auto-Extension Letter of Credit”); provided that any such Auto-Extension Letter of Credit must permit the L/C Issuer to prevent any such extension 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 “Non-Extension 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, the applicable Borrower shall not be required to make a specific request to the L/C Issuer for any such automatic extension. Once an Auto-Extension 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 extension of such Letter of Credit at any time to an expiry date not later than the Letter of Credit Expiration Date; provided, however, that the L/C Issuer shall not permit any such extension if (A) the L/C Issuer has determined that it would not be permitted, or would have no obligation, at such time to issue such Letter of Credit in its revised form (as extended) under the terms hereof (by reason of the provisions of clause (ii) or (iii) of Section 2.03(a) or otherwise), or (B) it has received notice (which may be by telephone or in writing) on or before the day that is seven Business Days before the Non-Extension Notice Date (1) from the Administrative Agent that the Required Lenders have elected not to permit such extension or (2) from the Administrative Agent, any Lender or the applicable Borrower that one or more of the applicable conditions specified in Section 4.02 is not then satisfied, and in each such case directing the L/C Issuer not to permit such extension; provided, however, that the parties agrees that clauses (A) and (B) above set forth the only circumstances under which the L/C Issuer may not permit any such extension.

(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 applicable Borrower and the Administrative Agent thereof and shall state the date payment shall be made by the L/C Issuer under a Letter of Credit (each such date, an “Honor Date”). Not later than one Business Day after the Honor Date, the applicable Borrower shall reimburse the L/C Issuer through the Administrative Agent in an amount equal to the amount of such drawing. If the applicable Borrower fails to so reimburse the L/C Issuer by 11:00 a.m. on the Honor Date, the Administrative Agent shall promptly notify each Lender thereof, the amount of the unreimbursed drawing (the “Unreimbursed Amount”), and the amount of such Lender’s Applicable Percentage thereof. In such event, the applicable Borrower shall be deemed to have requested a 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 for the principal amount of Base Rate Loans, but subject to the amount of the unutilized portion of the Aggregate Commitments and the conditions set forth in Section 4.02 (other than the delivery of a 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 immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice.

(ii) Each Lender shall upon any notice pursuant to Section 2.03(c)(i) make funds available (and through its applicable Lending Office to the Administrative Agent may apply Cash Collateral provided for this purpose) for the account of the L/C Issuer at the Administrative Agent’s Office in an amount equal to its Applicable Percentage 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 applicable 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 Borrowing of Base Rate Loans because the conditions set forth in Section 4.02 cannot be satisfied or for any other reason, the applicable 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 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 Applicable Percentage of such amount shall be solely for the account of the L/C Issuer.

(v) Each Lender’s obligation to make 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, the Administrative Agent, a 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, however, that each Lender’s obligation to make Loans pursuant to this Section 2.03(c) is subject to the conditions set forth in Section 4.02 (other than delivery by the applicable Borrower of a Loan Notice). No such making of an L/C Advance shall relieve or otherwise impair the obligation of the applicable 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 greater of the Federal Funds Rate and a rate determined by the L/C Issuer in accordance with banking industry rules on interbank compensation. A certificate of the L/C Issuer submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this clause (vi) shall be conclusive absent manifest error.

(d) Repayment of Participations.

(i) 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), if 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 applicable Borrower or otherwise, including proceeds of Cash Collateral applied thereto by the Administrative Agent), the Administrative Agent will distribute to such Lender its Applicable Percentage 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(c)(i) is required to be returned under any of the circumstances described in Section 10.05 (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 Applicable Percentage 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 Federal Funds Rate from time to time in effect. The obligations of the Lenders under this clause shall survive the payment in full of the Obligations and the termination of this Agreement.

(e) Obligations Absolute. The obligation of a Borrower to reimburse the L/C Issuer for each drawing under such Borrower’s Letter of Credit and to repay such Borrower’s L/C Borrowing 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 Loan Document or any other agreement or instrument relating thereto;

(ii) the existence of any claim, counterclaim, setoff, defense or other right that such Borrower or any 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, except for such payments made as a result of the L/C Issuer’s gross negligence, willful misconduct or bad faith; 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; or

(v) 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 or any Subsidiary.

The applicable Borrower shall promptly examine a copy of each Letter of Credit 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 immediately notify the L/C Issuer. Such 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 agrees 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, the Administrative Agent, any related parties nor any correspondent, participant or assignee 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, willful misconduct or bad faith; or (iii) the due execution, effectiveness, validity or enforceability of any document or instrument related to any Letter of Credit or Issuer Document. 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, however, that this assumption is not intended to, and shall not, preclude the applicable Borrower from 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, the Administrative Agent, any of their respective Related Parties nor any correspondent, participant or assignee of the L/C Issuer, shall be liable or responsible for any of the matters described in clauses (i) through (v) of Section 2.03(e); provided, however, that anything in such clauses to the contrary notwithstanding, the applicable 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 it proves were caused by the L/C Issuer’s willful misconduct or gross negligence or the L/C Issuer’s willful 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) Applicability of ISP98. Unless otherwise expressly agreed by the L/C Issuer and the Borrowers when a Letter of Credit is issued (including any such agreement applicable to an Existing Letter of Credit), the rules of the ISP shall apply to each Letter of Credit.

(h) Letter of Credit Fees. Each Borrower shall be severally liable for, and shall pay to the Administrative Agent for the account of each Lender in accordance with its Applicable Percentage a letter of credit fee (the “Letter of Credit Fee”) for each such Borrower’s Letter of Credit equal to the Applicable Margin for Borrowings at the Eurodollar Rate times the daily amount available to be drawn under such Letter of Credit. For purposes of computing the daily amount available to be drawn under any Letter of Credit, the amount of such Letter of Credit shall be determined in accordance with Section 1.06. Letter of Credit Fees shall be (i) computed on a quarterly basis in arrears and (ii) 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 (or, in the case of Existing Letters of Credit, the Closing Date), on the Letter of Credit Expiration Date and thereafter on demand. If there is any change in the Applicable Margin for Borrowings at the Eurodollar Rate during any quarter, the daily amount available to be drawn under each Letter of Credit shall be computed and multiplied by the Applicable Margin for Borrowings at the Eurodollar Rate separately for each period during such quarter that such Applicable Margin for Borrowings at the Eurodollar Rate was in effect. Notwithstanding anything to the contrary contained herein, upon the request of the Required Lenders, while any Event of Default exists, all Letter of Credit Fees shall accrue at the Default Rate.

(i) Fronting Fee and Documentary and Processing Charges Payable to L/C Issuer. Each Borrower shall be severally liable for, and shall pay directly to the L/C Issuer for its own account a fronting fee with respect to each such Borrower’s Letter of Credit, at a rate equal to 0.125% per annum, computed on the daily amount available to be drawn under such Letter of Credit, payable quarterly in arrears as provided in the next sentence. Such fronting fee shall be due and payable on the tenth Business Day after the end of each March, June, September and December in respect of the most recently-ended quarterly period (or portion thereof, in the case of the first such payment), commencing with the first such date to occur after the issuance of such Letter of Credit (or, in the case of Existing Letters of Credit, the Closing Date), on the Letter of Credit Expiration Date and thereafter on demand. For purposes of computing the daily amount available to be drawn under any Letter of Credit, the amount of such Letter of Credit shall be determined in accordance with Section 1.06. In addition, each Borrower shall be severally liable for, and 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 and standard costs and charges are due and payable on demand and are nonrefundable.

(j) Conflict with Issuer Documents. In the event of any conflict between the terms hereof and the terms of any Issuer Document, the terms hereof shall control.

2.04 Swing Line Loans.

(a) The Swing Line. Subject to the terms and conditions set forth herein, the Swing Line Lender agrees, in reliance upon the agreements of the other Lenders set forth in this Section 2.04, to make loans in Dollars (each such loan, a “Swing Line Loan”) to the Borrowers severally from time to time on any Business Day during the Availability Period in an aggregate amount not to exceed at any time outstanding the amount of the Swing Line Sublimit,

notwithstanding the fact that such Swing Line Loans, when aggregated with the Applicable Percentage 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, however, that after giving effect to any Swing Line Loan, (i) the Total Outstandings shall not exceed the Aggregate Commitments, and (ii) the aggregate Outstanding Amount of the Loans of any Lender, plus such Lender’s Applicable Percentage of the Outstanding Amount of all L/C Obligations, plus such Lender’s Applicable Percentage of the Outstanding Amount of all Swing Line Loans shall not exceed such Lender’s Commitment, and provided, further, that the Borrowers shall not use the proceeds of any Swing Line Loan to refinance any outstanding Swing Line Loan. 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 bear interest at the Base Rate plus the Applicable Margin. 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 a risk participation in such Swing Line Loan in an amount equal to the product of such Lender’s Applicable Percentage times the amount of such Swing Line Loan.

(b) Borrowing Procedures. Each Swing Line Borrowing shall be made upon a 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 $5,000,000 or a whole multiple of $100,000 in excess thereof, and (ii) the requested borrowing date, which shall be a Business Day. Each telephonic notice by the applicable Borrower 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 such 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 the 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 ARTICLE IV 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 applicable Borrower at its office by crediting the account of such Borrower designated on the books of the Swing Line Lender in immediately available funds.

(i) The Swing Line Lender at any time in its sole and absolute discretion may request, on behalf of the applicable Borrower (which hereby irrevocably authorizes the Swing Line Lender to so request on its behalf), that each Lender make, through its applicable Lending Office, a Base Rate Loan in an amount equal to such Lender’s

Applicable Percentage of the amount of Swing Line Loans then outstanding. Such request shall be made in writing (which written request shall be deemed to be a Loan Notice for purposes hereof) and in accordance with the requirements of Section 2.02, 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 Commitments and the conditions set forth in Section 4.02. The Swing Line Lender shall furnish the applicable Borrower with a copy of the applicable Loan Notice promptly after delivering such notice to the Administrative Agent. Each Lender shall make an amount equal to its Applicable Percentage of the amount specified in such Loan Notice available to the Administrative Agent in immediately available funds (and the Administrative Agent may apply Cash Collateral available with respect to the applicable Swing Line Loan) 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 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 applicable 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 Borrowing in accordance with Section 2.04(c)(i), 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 the relevant Swing Line Loan and each 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 greater of the Federal Funds Rate and a rate determined by the Swing Line Lender in accordance with banking industry rules on interbank compensation. 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 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, a 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, however, that each Lender’s obligation to make Loans pursuant to this Section 2.04(c) is subject to the conditions set forth in Section 4.02. No such funding of risk participations shall relieve or otherwise impair the obligation of the applicable 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 Applicable Percentage 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 10.05 (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 Applicable Percentage 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 Federal Funds Rate. The Administrative Agent will make such demand upon the request of the Swing Line Lender. The obligations of the Lenders under this clause shall survive the payment in full of the Obligations and the termination of this Agreement.

(e) Interest for Account of Swing Line Lender. The Swing Line Lender shall be responsible for invoicing the applicable 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 Applicable Percentage of any Swing Line Loan, interest in respect of such Applicable Percentage shall be solely for the account of the Swing Line Lender.

(f) Payments Directly to Swing Line Lender. Each Borrower shall be severally liable for, and shall make all payments of principal and interest in respect of, the Swing Line Loans of such Borrower directly to the Swing Line Lender.

2.05 Prepayments.

(a) A Borrower may, upon notice to the Administrative Agent, at any time or from time to time voluntarily, prepay its Loans in whole or in part without premium or penalty; provided that (i) such notice must be received by the Administrative Agent not later than 10:00 a.m. (A) three Business Days prior to any date of prepayment of Eurodollar Rate Loans and (B) on the date of prepayment of Base Rate Loans; (ii) any prepayment of Eurodollar Rate Loans shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof; and (iii) any prepayment of Base Rate Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof or, in each case, if less, the entire principal amount thereof then outstanding. Each such notice shall specify the date and amount of such prepayment and the Type(s) of Loans to be prepaid. The Administrative Agent will promptly notify each Lender of its receipt of each such notice, and of the amount of such Lender’s Applicable Percentage of such prepayment. Such Borrower shall irrevocably 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 on the amount prepaid, together with any additional amounts required pursuant to Section 3.05. Each such prepayment shall be applied to the Loans of the Lenders in accordance with their respective Applicable Percentages.

(b) A 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 its Swing Line Loans in whole or in part without premium or penalty; provided that (i) such notice must be received by the Swing Line Lender and the Administrative Agent not later than 1:00 p.m. on the date of the prepayment, and (ii) any such prepayment shall be in a minimum principal amount of $100,000. Each such notice shall specify the date and amount of such prepayment. Such Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein.

(c) If for any reason the Total Outstandings at any time exceed the Aggregate Commitments then in effect, the applicable Borrower shall be liable for and shall immediately prepay its or their Loans, as applicable, and/or Cash Collateralize its or their L/C Obligations, as applicable, in an aggregate amount equal to such excess; provided, however, that the Borrowers shall not be required to Cash Collateralize the L/C Obligations pursuant to this Section 2.05(c), unless after the prepayment in full of the Loans and Swing Line Loans, the Total Outstandings exceed the Aggregate Commitments then in effect.

2.06 Termination or Reduction of Commitments. The Borrowers may, upon notice to the Administrative Agent, terminate the unutilized portion of the Aggregate Commitments, or from time to time permanently reduce the Aggregate Commitments; provided that (i) any such notice shall be received by the Administrative Agent not later than 10:00 a.m. on the date of termination or reduction, (ii) any such partial reduction shall be in an aggregate amount of $5,000,000 or any whole multiple of $1,000,000 in excess thereof, (iii) the Borrowers shall not terminate or reduce the Aggregate Commitments if, after giving effect thereto and to any concurrent prepayments hereunder, the Total Outstandings would exceed the Aggregate Commitments, and (iv) if, after giving effect to any reduction of the Aggregate Commitments, the Letter of Credit Sublimit or the Swing Line Sublimit exceeds the amount of the Aggregate Commitments, such sublimit shall be automatically reduced by the amount of any such excess. The Administrative Agent will promptly notify the Lenders of any such notice of termination or reduction of the Aggregate Commitments. Any reduction of the Aggregate Commitments shall be applied to the Commitment of each Lender according to its Applicable Percentage. All fees accrued until the effective date of any termination of the Aggregate Commitments shall be paid on the effective date of such termination.

2.07 Repayment of Loans. (a) Each Borrower shall be severally liable for, and shall repay to the Lenders on the Maturity Date for Loans of such Borrower, the Outstanding Amount of such Loans on such date.

(b) Each Borrower shall be severally liable for, and shall repay each Swing Line Loan of such Borrower, on the earlier to occur of (i) the date that is ten Business Days after such Swing Line Loan is made, if requested by the Administrative Agent on behalf of the Swing Line Lender and (ii) the Maturity Date.

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 Margin; (ii) each Base Rate Loan (other than Swing Line Loans) 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 Margin; 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 Margin.

(b) (i) If any amount of principal of any Loan or Swing Line Loan is not paid when due by the applicable Borrower (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, such amount shall thereafter bear interest at a fluctuating rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws.

(ii) If any amount (other than principal of any Loan or Swing Line Loan) payable by the applicable Borrower under any Loan Document is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, then, upon the request of the Required Lenders, such amount shall thereafter bear interest at a fluctuating rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws.

(iii) 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.

2.09 Fees. Each Borrower shall be severally liable for, and shall pay to the Administrative Agent for the account of each Lender, a non-refundable commitment fee calculated at the Applicable Commitment Fee Rate, times the actual daily amount of the undrawn Aggregate Commitment. Such commitment fee shall commence accruing on the Closing Date, 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. If there is any change in the Applicable Commitment Fee Rate during any quarter, the actual daily amount shall be computed and multiplied by the Applicable Commitment Fee Rate separately for each period during such quarter that such Applicable Commitment Fee Rate was in effect.

2.10 Computation of Interest and Fees. All computations of interest for Base Rate

Loans and Swing Line Loans, when the Base Rate is determined by Bank of America’s “prime rate”, shall be made on the basis of a year of 365 or 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 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 365-day year). Interest shall accrue on each Loan and each Swing Line Loan for the day on which the Loan or Swing Line Loan is made, and shall not accrue on a Loan or Swing Line Loan, or any portion thereof, for the day on which the Loan or Swing Line Loan or such portion is paid; provided that any Loan or Swing Line Loan that is repaid on the same day on which it is made shall, subject to Section 2.12(a), bear interest for one 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.

2.11 Evidence of Debt.

(a) The Credit Extensions made by each Lender shall be evidenced by one or more accounts or records maintained by such Lender and by the Administrative Agent in the ordinary course of business. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of a Borrower hereunder to pay any amount owing with respect to its 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 and shall be conclusive in the absence of manifest error. Upon the request of any Lender to a Borrower made through the Administrative Agent, such Borrower shall execute and deliver to such Lender (through the Administrative Agent) a Note, 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.

(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 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 by each Lender in its accounts pursuant to Section 2.11(a), shall be prima facie evidence of the amount of principal and interest due and payable or to become due and payable from a Borrower 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 any 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 such Borrower under this Agreement and the other Loan Documents.

2.12 Payments Generally; Administrative Agent’s Clawback.

(a) General. All payments to be made by a Borrower shall be made without condition or deduction for any counterclaim, defense, recoupment or setoff. Except as otherwise expressly provided herein, all payments by a Borrower 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 Applicable Percentage (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 2:00 p.m. shall be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue. If any payment to be made by a Borrower shall become due on a day other than a Business Day, 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.

(b) (i) Funding by Lenders; Presumption by Administrative Agent. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing of Eurodollar Rate Loans (or, in the case of any Borrowing of Base Rate Loans, prior to 12:00 noon on the date of such Borrowing) that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.02 (or, in the case of a Borrowing of Base Rate Loans, that such Lender has made such share available in accordance with and at the time required by Section 2.02) and may, in reliance upon such assumption, make available to the applicable Borrower a corresponding amount. In such event, if a Lender has not, in fact, made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the applicable Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount in immediately available funds, with interest thereon, for each day from and including the date such amount is made available to such Borrower to but excluding the date of payment to the Administrative Agent, at (A) in the case of a payment to be made by such Lender, the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation, plus any administrative, processing or similar fees customarily charged by the Administrative Agent in connection with the foregoing, and (B) in the case of a payment made by a Borrower, the interest rate applicable to Base Rate Loans. If such Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to such Borrower the amount of such interest paid by such Borrower for such period. If such Lender pays its share of the applicable Borrowing to the Administrative Agent, then the amount so paid shall constitute such Lender’s Loan included in such Borrowing. Any payment by a Borrower shall be without prejudice to any claim such Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent.

(ii) Payments by the Borrowers; Presumptions by Administrative Agent. Unless the Administrative Agent shall have received notice from the applicable Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the L/C Issuer hereunder that such Borrower will not make such

payment, the Administrative Agent may assume that such Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the L/C Issuer, as the case may be, the amount due. In such event, if such Borrower has not in fact made such payment, then each of the Lenders or the L/C Issuer, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or the L/C Issuer, in immediately available funds with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation plus any administrative, processing or similar fees customarily charged by the Administrative Agent in connection with the foregoing.

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

(c) Failure to Satisfy Conditions Precedent. 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 II, and such funds are not made available to the applicable Borrower by the Administrative Agent because the conditions to the applicable Credit Extension set forth in ARTICLE IV 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 promptly, without interest.

(d) Obligations of Lenders Several. The obligations of the Lenders hereunder to make Loans and to fund participations in Letters of Credit and Swing Line Loans and the obligations of the Lenders to make payments pursuant to Section 10.04(c) are several and not joint. The failure of any Lender to make any Loan, to fund any such participation or to make any payment under Section 10.04(c) 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, to purchase its participation or to make its payment under Section 10.04(c).

(e) Funding Source. 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.

2.13 Sharing of Payments by Lenders. If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of the Loans made by it, or the participations in L/C Obligations or in Swing Line Loans held by it, resulting in such Lender receiving payment of a proportion of the aggregate amount of such Loans or participations and accrued interest thereon greater than its pro rata share thereof as provided herein, then the Lender receiving such greater proportion shall (a) notify the Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans and subparticipations in L/C Obligations and Swing Line Loans of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and other amounts owing them, provided that:

(i) if any such participations or subparticipations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations or subparticipations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and

(ii) the provisions of this Section 2.13 shall not be construed to apply to (x) any payment made by a Borrower pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender), (y) the application of Cash Collateral provided for in Section 2.14 or (z) any payment obtained by a Lender as consideration for the assignment of, or sale of a participation in, any of its Loans or subparticipations in L/C Obligations or Swing Line Loans to any assignee or participant, other than to a Borrower or any of its Subsidiaries (as to which the provisions of this Section 2.13 shall apply).

Each Borrower consents to the foregoing and agrees, to the extent they may effectively do so under applicable Law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against its rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Borrower in the amount of such participation.

2.14 Cash Collateral.

(a) Certain Credit Support Events. At any time that there shall exist a Defaulting Lender, promptly upon the request of the Administrative Agent, the L/C Issuer or the Swing Line Lender, the applicable Borrower shall deliver to the Administrative Agent Cash Collateral in an amount sufficient to cover all Fronting Exposure (after giving effect to Section 2.15(a)(iv) and any Cash Collateral provided by the Defaulting Lender). In addition, 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, or (ii) if, as of the Letter of Credit Expiration Date, any L/C Obligation for any reason remains outstanding, the applicable Borrower shall, in each case, immediately Cash Collateralize the then Outstanding Amount of all its L/C Obligations. Section 2.05 and Section 8.02(c) set forth certain additional requirements to deliver Cash Collateral hereunder. For purposes of this Section 2.14, Section 2.05 and Section 8.02(c), “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 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). “Cash Collateral” shall have a meaning correlative to the foregoing and shall include the proceeds of such cash collateral and other credit support. Derivatives of such term have corresponding meanings. The applicable Borrower hereby grants to the Administrative Agent, for the benefit of the L/C Issuer and the Lenders, a security interest in all such cash, deposit accounts and all balances therein and all proceeds of the foregoing. Cash Collateral shall be maintained in blocked, non-interest bearing deposit accounts at Bank of America.

(b) Grant of Security Interest. All Cash Collateral (other than credit support not constituting funds subject to deposit) shall be maintained in blocked, non-interest bearing deposit accounts at Bank of America. The applicable Borrower, and to the extent provided by any Lender, such Lender, hereby grants to (and subjects to the control of) the Administrative Agent, for the benefit of the Administrative Agent, the L/C Issuer and the Lenders (including the Swing Line Lender), and agrees to maintain, a first priority security interest in all such cash, deposit accounts and all balances therein, and all other property so provided as collateral pursuant hereto, and in all proceeds of the foregoing, all as security for the obligations to which such Cash Collateral may be applied pursuant to Section 2.14(c). If at any time the Administrative Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Administrative Agent as herein provided, or that the total amount of such Cash Collateral is less than the applicable Fronting Exposure and other obligations secured thereby, the applicable Borrower or the relevant Defaulting Lender will, promptly upon demand by the Administrative Agent, pay or provide to the Administrative Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency.

(c) Application. Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under any of this Section 2.14 or Section 2.03, Section 2.04, Section 2.05, Section 2.15 or Section 8.02 in respect of Letters of Credit or Swing Line Loans shall be held and applied to the satisfaction of the specific L/C Obligations, Swing Line Loans, obligations to fund participations therein (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) and other obligations for which the Cash Collateral was so provided, prior to any other application of such property as may be provided for herein.

(d) Release. Cash Collateral (or the appropriate portion thereof) provided to reduce Fronting Exposure or other obligations shall be released promptly following (i) the elimination of the applicable Fronting Exposure or other obligations giving rise thereto (including by the termination of Defaulting Lender status of the applicable Lender (or, as appropriate, its assignee following compliance with Section 10.06(b)(vi))) or (ii) the Administrative Agent’s good faith determination that there exists excess Cash Collateral; provided, however, (x) that Cash Collateral furnished by or on behalf of a Loan Party shall not be released during the continuance of a Default or Event of Default (and following application as provided in this Section 2.14 may be otherwise applied in accordance with Section 8.03), and (y) the Person providing Cash Collateral and the L/C Issuer or Swing Line Lender, as applicable, may agree that Cash Collateral shall not be released but instead held to support future anticipated Fronting Exposure or other obligations.

2.15 Defaulting Lenders.

(a) Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as that Lender is no longer a Defaulting Lender, to the extent permitted by applicable Law:

(i) Waivers and Amendments. That Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in Section 10.01.

(ii) Reallocation of Payments. Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of that Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to ARTICLE VIII or otherwise, and including any amounts made available to the Administrative Agent by that Defaulting Lender pursuant to Section 10.08), shall be applied at such time or times as may be determined by the Administrative Agent (or, in the case of the fourth clause below, as requested by the applicable Borrower) as follows: first, to the payment of any amounts owing by that Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by that Defaulting Lender to the L/C Issuer or Swing Line Lender hereunder; third, if so determined by the Administrative Agent or requested by the L/C Issuer or Swing Line Lender, to be held as Cash Collateral for future funding obligations of that Defaulting Lender of any participation in any Swing Line Loan or Letter of Credit; fourth, as the applicable Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which that Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent and the applicable Borrower, to be held in a non-interest bearing deposit account and released in order to satisfy obligations of that Defaulting Lender to fund Loans under this Agreement; sixth, to the payment of any amounts owing to the Lenders, the L/C Issuer or Swing Line Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender, the L/C Issuer or Swing Line Lender against that Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the applicable Borrower as a result of any judgment of a court of competent jurisdiction obtained by the applicable Borrower against that Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to that Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans or L/C Borrowings in respect of which that Defaulting Lender has not fully funded its appropriate share and (y) such Loans or L/C Borrowings were made at a time when the conditions set forth in Section 4.02 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and L/C Borrowings owed to, all non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or L/C Borrowings owed to, that Defaulting Lender. Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 2.15(a)(iv) shall be deemed paid to and redirected by that Defaulting Lender, and each Lender irrevocably consents hereto.

(iii) Certain Fees. That Defaulting Lender (x) shall not be entitled to receive any commitment fee pursuant to Section 2.09 for any period during which that Lender is a Defaulting Lender (and the Borrowers shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender) and (y) shall be limited in its right to receive Letter of Credit Fees as provided in Section 2.03(h).

(iv) Reallocation of Applicable Percentages to Reduce Fronting Exposure. During any period in which there is a Defaulting Lender, for purposes of computing the amount of the obligation of each non-Defaulting Lender to acquire, refinance or fund participations in Letters of Credit or Swing Line Loans pursuant to Section 2.03 and Section 2.04, the “Applicable Percentage” of each non-Defaulting Lender shall be computed without giving effect to the Commitment of that Defaulting Lender; provided, that the aggregate obligation of each non-Defaulting Lender to acquire, refinance or fund participations in Letters of Credit and Swing Line Loans shall not exceed the positive difference, if any, of (x) the Commitment of that non-Defaulting Lender minus (y) the aggregate Outstanding Amount of the Loans of that Lender, and shall in no event exceed such non-Defaulting Lender’s Commitment.

(b) Defaulting Lender Cure. If the Borrowers, the Administrative Agent, Swing Line Lender and the L/C Issuer agree in writing in their sole discretion that a Defaulting Lender should no longer be deemed to be a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), that Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit and Swing Line Loans to be held on a pro rata basis by the Lenders in accordance with their Applicable Percentages (without giving effect to Section 2.15(a)(iv)), whereupon that Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of either Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

2.16 Gilead Ireland. The Parent may from time to time, upon not less than three Business Days’ notice from the Parent to the Administrative Agent (or such shorter period as may be agreed by the Administrative Agent in its sole discretion), terminate Gilead Ireland’s status as a Borrower hereunder; provided that there are no outstanding Loans payable by, or Letters of Credit issued for the account of, Gilead Ireland, or any other Obligations hereunder (other than contingent, unasserted indemnification obligations) of Gilead Ireland remaining unpaid or unsatisfied as of the effective date of such termination (and any such termination purporting to become effective while any outstanding Loans are payable by, or Letters of Credit have been issued for the account of, Gilead Ireland, or any other Obligations hereunder (other than contingent, unasserted indemnification obligations) of Gilead Ireland remaining unpaid or unsatisfied shall be null and void); provided further, that the Administrative Agent, the L/C Issuer, the Swing Line Lender and the other Lenders shall reasonably cooperate with Gilead Ireland to amend or replace any Letter of Credit in order to name the Parent as the applicant or account party with respect to any Letter of Credit issued for the account of Gilead Ireland. The Administrative Agent will promptly notify the Lenders of any such termination of Gilead Ireland's status as a Borrower.

ARTICLE III

TAXES, YIELD PROTECTION AND ILLEGALITY

3.01 Taxes.

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of either Borrower hereunder or under any other Loan Document shall be made free and clear of and without deduction or withholding for any Indemnified Taxes (including Other Taxes), provided that if any Indemnified Taxes (including any Other Taxes) are required by applicable Law to be withheld or deducted from such payments by either Borrower, then (i) the sum payable by the applicable Borrower shall be increased as necessary so that after making all required deductions or withholdings (including deductions or withholdings applicable to additional sums payable under this Section 3.01) each of the Administrative Agent, the applicable Lender or the L/C Issuer, as the case may be, receives an amount equal to the sum it would have received had no such deductions or withholdings been made, (ii) the applicable Borrower shall make such deductions or withholdings as required by Law and (iii) the applicable Borrower shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable Law.

(b) Payment of Other Taxes by the Borrowers. Without limiting the provisions of Section 3.01(a), the applicable Borrower shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with applicable Law.

(c) Indemnification by the Borrowers. Each Borrower severally agrees to indemnify the Administrative Agent, each Lender and the L/C Issuer, within ten days after demand therefor, for the full amount of any such Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 3.01) as are attributable to the Borrowings or Swing Line Borrowings of such Borrower paid by the Administrative Agent, such Lender or the L/C Issuer, as the case may be, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate setting forth in reasonable detail the basis for and calculation of the amount of such payment or liability delivered to the Parent by a Lender or the L/C Issuer (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender or the L/C Issuer, shall be conclusive absent manifest error.

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

(e) Status of Lenders. Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the Law of the jurisdiction in which a Borrower is resident for tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments hereunder or under any other Loan Document shall deliver to such Borrower (with a copy to the Administrative Agent), to the extent it is legally entitled to do so, at the time or times prescribed by applicable Law or reasonably requested by such Borrower or the Administrative Agent, such properly completed and executed documentation prescribed by applicable Law as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender to a Loan to a U.S. Borrower, if requested by such Borrower or the Administrative Agent, to the extent it is legally entitled to do so, shall deliver such other documentation prescribed by applicable Law or reasonably requested by such Borrower or the Administrative Agent as will enable such Borrower or the Administrative Agent to determine whether or not such Lender is subject to U.S. backup withholding or U.S. information reporting requirements.

Without limiting the generality of the foregoing, in the case of a Foreign Lender to a Loan to a U.S. Borrower, such Foreign Lender shall deliver to such U.S. Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender to such U.S. Borrower under this Agreement (and from time to time thereafter upon the request of such U.S. Borrower or the Administrative Agent or upon expiration), but only if such Foreign Lender is legally entitled to do so, whichever of the following is applicable:

(i) duly completed originals of Internal Revenue Service Form W-8BEN claiming eligibility for benefits of an income tax treaty to which the United States is a party,

(ii) duly completed originals of Internal Revenue Service Form W-8ECI,

(iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit H hereto and (y) duly completed originals of Internal Revenue Service Form W-8BEN, or

(iv) any other form prescribed by applicable Law as a basis for claiming exemption from or a reduction in United States Federal withholding tax duly completed together with such supplementary documentation as may be prescribed by applicable Law to permit such U.S. Borrower to determine the withholding or deduction required to be made.

(f) Treatment of Certain Refunds. If the Administrative Agent, any Lender or the L/C Issuer determines, in its sole discretion, exercised in good faith, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by a Borrower or with respect to which such Borrower has paid additional amounts pursuant to this Section 3.01, it shall pay to such Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by such Borrower under this Section 3.01 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent, such Lender or the L/C Issuer, as the case may be, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund), provided that such Borrower, upon the request of the Administrative Agent, such Lender or the L/C Issuer, agrees to repay the amount paid over to such Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent, such Lender or the L/C Issuer in the event the Administrative Agent, such Lender or the L/C Issuer is required to repay such refund to such Governmental Authority. This Section 3.01(f) shall not be construed to require the Administrative Agent, any Lender or the L/C Issuer to make available its tax returns (or any other information relating to its taxes that it deems confidential) to the Borrowers or any other Person.

(g) FATCA Compliance. If a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the relevant Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by such Borrower or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by such Borrower or the Administrative Agent as may be necessary for such Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 3.01(g), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

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, or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or to take deposits of, Dollars in the London interbank market, then, on notice thereof by such Lender to the applicable Borrower through the Administrative Agent, (i) any obligation of such Lender to make or continue Eurodollar Rate Loans or to convert Base Rate Loans to Eurodollar Rate Loans shall be suspended, and (ii) if such notice asserts the illegality of such Lender making or maintaining Base Rate Loans the interest rate on which is determined by reference to the Eurodollar Rate component of the Base Rate, the interest rate on which Base Rate Loans of such Lender shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to the Eurodollar Rate component of the Base Rate, in each case until such Lender notifies the Administrative Agent and the applicable Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, (x) the applicable Borrower shall, upon demand from such Lender (with a copy to the Administrative Agent), be severally liable for, and shall prepay or, if applicable, convert all such Borrower’s Eurodollar Rate Loans of such Lender to Base Rate Loans (the interest rate on which Base Rate Loans of such Lender shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to the Eurodollar Rate component of the Base Rate), 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 and (y) if such notice asserts the illegality of such Lender determining or charging interest rates based upon the Eurodollar Rate, the Administrative Agent shall during the period of such suspension compute the Base Rate applicable to such Lender without reference to the Eurodollar Rate component thereof until the Administrative is advised in writing by such Lender that it is no longer illegal for such Lender to determine or charge interest rates based upon the Eurodollar Rate. Upon any such prepayment or conversion, the applicable Borrower shall also be severally liable for, and shall pay accrued interest on the amount so prepaid or converted.

3.03 Inability to Determine Rates. If the Required Lenders determine that for any reason in connection with any request for a Eurodollar Rate Loan or a conversion to or continuation thereof by the applicable Borrower that (a) Dollar deposits are not being offered to banks in the London interbank eurodollar market for the applicable amount and Interest Period of such Eurodollar Rate Loan, (b) 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 (c) 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, the Administrative Agent will promptly so notify the applicable Borrower and each Lender. Thereafter, (x) the obligation of the Lenders to make or maintain Eurodollar Rate Loans shall be suspended, and (y) in the event of a determination described in the preceding sentence with respect to the Eurodollar Rate component of the Base Rate, the utilization of the Eurodollar Rate component in determining the Base Rate shall be suspended, in each case until the Administrative Agent (upon the instruction of the Required Lenders) revokes such notice. Upon receipt of such notice, the applicable 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.

3.04 Increased Costs; Reserves on Eurodollar Rate Loans.

(a) Increased Costs Generally. If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement reflected in the Eurodollar Rate) or the L/C Issuer;

(ii) subject any Lender or the L/C Issuer to any Tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any participation in a Letter of Credit or any Eurodollar Rate Loan made by it, or change the basis of taxation of payments to such Lender or the L/C Issuer in respect thereof (except for Indemnified Taxes or Other Taxes covered by Section 3.01 and the imposition of, or any change in the rate of, any Excluded Tax payable by such Lender or the L/C Issuer); or

(iii) impose on any Lender or the L/C Issuer or the London interbank market any other condition, cost or expense affecting this Agreement or Eurodollar Rate Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Rate Loan (or of maintaining its obligation to make any such Loan), or to increase the cost to such Lender or the L/C Issuer of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender or the L/C Issuer hereunder (whether of principal, interest or any other amount) then, upon request of such Lender or the L/C Issuer, the applicable Borrower shall be severally liable for, and shall pay to such Lender or the L/C Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or the L/C Issuer, as the case may be, for such additional costs incurred or reduction suffered.

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

(c) Certificates for Reimbursement. A certificate of a Lender or the L/C Issuer setting forth the amount or amounts necessary to compensate such Lender or the L/C Issuer or its holding company, as the case may be, as specified in Sections 3.04(a) or 3.04(b) and delivered to the applicable Borrower (with a copy to the Administrative Agent) shall be conclusive absent manifest error. The applicable Borrower shall be severally liable for, and shall pay such Lender or the L/C Issuer, as the case may be, the amount shown as due on any such certificate within 30 days after receipt thereof.

(d) Delay in Requests. Failure or delay on the part of any Lender or the L/C Issuer to demand compensation pursuant to the foregoing provisions of this Section 3.04 shall not constitute a waiver of such Lender’s or the L/C Issuer’s right to demand such compensation, provided that the applicable Borrower shall not be required to compensate a Lender or the L/C Issuer pursuant to the foregoing provisions of this Section 3.04 for any increased costs incurred or reductions suffered more than six months prior to the date that such Lender or the L/C Issuer, as the case may be, notifies the applicable Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the L/C Issuer’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the six-month period referred to above shall be extended to include the period of retroactive effect thereof).

3.05 Compensation for Losses. Upon demand of any Lender (with a copy to the Administrative Agent) from time to time, the applicable Borrower shall be severally liable for, and shall promptly compensate such Lender for and hold such Lender harmless from any reasonable loss (other than lost profits), cost or expense incurred by it as a result of:

(a) any continuation, conversion, payment or prepayment of any such Borrower’s Loan other than a Base Rate Loan or Swing Line 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);

(b) any failure by such 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; or

(c) any assignment of a Eurodollar Rate Loan on a day other than the last day of the Interest Period therefor as a result of a request by such Borrower pursuant to Section 10.13;

including any reasonable 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. The applicable Borrower shall be severally liable for, and shall pay any reasonable and customary administrative fees charged by such Lender in connection with the foregoing.

For purposes of calculating amounts payable by the applicable Borrower to the Lenders under this Section 3.05, each Lender shall be deemed to have funded each such Borrower’s 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.

3.06 Mitigation Obligations; Replacement of Lenders.

(a) Designation of a Different Lending Office. If any Lender requests compensation under Section 3.04, or a Borrower is required to pay any additional amount to any Lender, the L/C Issuer or any Governmental Authority for the account of any Lender or the L/C Issuer pursuant to Section 3.01, or if any Lender gives a notice pursuant to Section 3.02, then such Lender or the L/C Issuer, as applicable, shall use reasonable efforts to designate a different Lending Office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender or the L/C Issuer, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 3.01 or Section 3.04, as the case may be, in the future, or eliminate the need for the notice pursuant to Section 3.02, as applicable, and (ii) in each case, would not subject such Lender or the L/C Issuer, as the case may be, to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender or the L/C Issuer, as the case may be. The applicable Borrower severally agrees to pay all reasonable costs and expenses incurred by any Lender or the L/C Issuer in connection with any such designation or assignment.

(b) Replacement of Lenders. If any Lender requests compensation under Section 3.04, or if a Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.01, such Borrower may replace such Lender in accordance with Section 10.13.

3.07 Survival. All of the Borrowers’ obligations under this ARTICLE III shall survive termination of the Aggregate Commitments, repayment of all other Obligations hereunder and resignation of the Administrative Agent.

The provisions of this ARTICLE IX are solely for the benefit of the Administrative Agent, the Lenders and the L/C Issuer, and the Borrowers shall not have rights as a third party beneficiary of any of such provisions.

9.02 Rights as a Lender. The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor to, or in any other advisory capacity for, and generally engage in any kind of business with, the Borrowers or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

9.03 Exculpatory Provisions.

The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents. Without limiting the generality of the foregoing, the Administrative Agent:

(a) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing;

(b) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents), provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or applicable Law; and

The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Section 10.01 and Section 8.02) or (ii) in the absence of its own gross negligence, willful misconduct or bad faith. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until notice describing such Default is given to the Administrative Agent by a Borrower, a Lender or the L/C Issuer.

The Administrative Agent shall not be responsible for, or have any duty to ascertain or inquire into, (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in ARTICLE IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or the L/C Issuer, the Administrative Agent may presume that such condition is satisfactory to such Lender or the L/C Issuer unless the Administrative Agent shall have received notice to the contrary from such Lender or the L/C Issuer prior to the making of such Loan or the issuance of such Letter of Credit. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrowers), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

If no such successor administrative agent shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may on behalf of the Lenders and the L/C Issuer, appoint a successor administrative agent meeting the qualifications set forth above; provided that if the Administrative Agent shall notify the Borrowers and the Lenders that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (1) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents and (2) all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender and the L/C Issuer directly, until such time as the Required Lenders appoint a successor administrative agent as provided for above in this Section 9.06.

9.07 Non-Reliance on Administrative Agent and Other Lenders. Each Lender and the L/C Issuer acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement.

9.09 Administrative Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to either Borrower, the Administrative Agent (irrespective of whether the principal of any Loan, Swing Line Loan or L/C Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on either Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise:

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, Swing Line Loans, L/C Obligations and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders, the L/C Issuer and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the L/C Issuer and the Administrative Agent and their respective agents and counsel and all other amounts due to the Lenders, the L/C Issuer and the Administrative Agent under Section 2.09 and Section 10.04) allowed in such judicial proceeding; and

Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender or the L/C Issuer any plan of

reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender or the L/C Issuer or to authorize the Administrative Agent to vote in respect of the claim of any Lender or the L/C Issuer in any such proceeding.

9.10 Withholding. To the extent required by any applicable Laws, the Administrative Agent may withhold from any payment to any Lender an amount equivalent to any applicable withholding Tax. If any payment has been made to any Lender by the Administrative Agent without the applicable withholding Tax being withheld from such payment and the Administrative Agent has paid over the applicable withholding Tax to the IRS or any other Governmental Authority, or the IRS or any other Governmental Authority asserts a claim that the Administrative Agent did not properly withhold Tax from amounts paid to or for the account of any Lender because the appropriate form was not delivered or was not properly executed or because such Lender failed to notify the Administrative Agent of a change in circumstance which rendered the exemption from, or reduction of, withholding Tax ineffective or for any other reason, such Lender shall indemnify the Administrative Agent fully for all amounts paid, directly or indirectly, by the Administrative Agent as Tax or otherwise, including any penalties or interest and together with all expenses (including legal expenses, allocated internal costs and out-of-pocket expenses) incurred.

The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided by Law.

(b) Notwithstanding anything to the contrary contained herein or in any other Loan Document, the authority to enforce rights and remedies hereunder and under the other Loan Documents against the Loan Parties or any of them shall be vested exclusively in, and all actions and proceedings at law in connection with such enforcement shall be instituted and maintained exclusively by, the Administrative Agent in accordance with Section 8.02 for the benefit of all the Lenders and the L/C Issuer; provided, however, that the foregoing shall not prohibit (a) the Administrative Agent from exercising on its own behalf the rights and remedies that inure to its benefit (solely in its capacity as Administrative Agent) hereunder and under the other Loan Documents, (b) the L/C Issuer or the Swing Line Lender from exercising the rights and remedies that inure to its benefit (solely in its capacity as L/C Issuer or Swing Line Lender, as the case may be) hereunder and under the other Loan Documents, (c) any Lender from exercising setoff rights in accordance with Section 10.08 (subject to the terms of Section 2.13) or (d) any Lender from filing proofs of claim or appearing and filing pleadings on its own behalf during the pendency of a proceeding relative to any Loan Party under any Debtor Relief Law; and provided, further, that if at any time there is no Person acting as Administrative Agent hereunder and under the other Loan Documents, then (i) the Required Lenders shall have the rights otherwise ascribed to the Administrative Agent pursuant to Section 8.02 and (ii) in addition to the matters set forth in clauses (b), (c) and (d) of the preceding proviso and subject to Section 2.13, any Lender may, with the consent of the Required Lenders, enforce any rights and remedies available to it and as authorized by the Required Lenders.

10.04 Expenses; Indemnity; Damage Waiver.

(a) Costs and Expenses. Each Borrower shall severally be liable to pay (i) all reasonable, invoiced out-of-pocket expenses incurred by the Administrative Agent and its Affiliates (including (a) the reasonable, invoiced out-of-pocket fees, charges and disbursements of one primary counsel for the Administrative Agent (and additional counsel for any actual or reasonably perceived conflict of interest and, if reasonably necessary, one special or regulatory counsel in multiple jurisdictions or one local counsel in each relevant jurisdiction (but no other counsels)) and (b) reasonable invoiced out-of-pocket due diligence expenses), in connection with the syndication of the credit facility provided for herein, the preparation, negotiation, execution, delivery and administration of this Agreement and the other Loan Documents or any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions

contemplated hereby or thereby shall be consummated; provided that the fees, charges and disbursement of the Administrative Agent and its Affiliates and their counsel with respect to the preparation, negotiation and delivery of the Loan Documents in connection with the Transaction shall be limited as set forth in the Commitment Letter), and (ii) all reasonable out-of-pocket expenses incurred by the L/C Issuer in connection with the issuance, amendment, renewal or extension of any Letter of Credit of such Borrower or any demand for payment thereunder and (iii) all reasonable out-of-pocket expenses incurred by the Administrative Agent, any Lender or the L/C Issuer, (including the reasonable, invoiced fees, charges and disbursements of one primary counsel for the Administrative Agent, the L/C Issuer, the Arrangers and the Lenders (and additional counsel for any actual or reasonably perceived conflict of interest and, if reasonably necessary, one special or regulatory counsel in multiple jurisdictions or one local counsel in each relevant jurisdiction (but no other counsels)) in connection with the enforcement or protection of its rights (a) in connection with this Agreement and the other Loan Documents, including its rights under this Section 10.04, or (b) in connection with the Loans or Swing Line Loans made or Letters of Credit issued hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans, Swing Line Loans or Letters of Credit.

(b) Indemnification by the Borrowers. Each Borrower will severally indemnify the Administrative Agent (and any sub-agent thereof), each Lender, the L/C Issuer and each Related Party of any of the foregoing Persons and their respective successors and assigns (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, such Borrower’s ratable share of any and all losses, claims, damages, liabilities and reasonable invoiced out-of-pocket expenses (including the reasonable invoiced out-of-pocket fees, disbursements and other charges of one outside counsel to all Indemnitees (and additional counsel for any actual or reasonably perceived conflict of interest and, to the extent reasonably necessary, one special or regulatory counsel in multiple jurisdictions and one local counsel in each relevant jurisdiction (but no other counsels))) incurred by any Indemnitee or asserted against any Indemnitee by any third party or by either Borrower arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or thereunder, the consummation of the transactions contemplated hereby or thereby, or, in the case of the Administrative Agent (and any sub-agent thereof) and its Related Parties only, the administration of this Agreement and the other Loan Documents (including in respect of any matters addressed in Section 3.01), (ii) any 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), (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by either Borrower or any of their respective Subsidiaries, or any Environmental Liability related in any way to either Borrower or any of their respective Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory, whether brought by a third party or by either Borrower, its equityholders or creditors, or an Indemnitee, and regardless of whether any Indemnitee is a party thereto, in all cases, whether or not caused by or arising, in whole or in part, out of the comparative, contributory or sole negligence of the Indemnitee; provided that such indemnity shall not, as to any Indemnitee,

be available to the extent that such losses, claims, damages, liabilities or reasonable invoiced out-of-pocket expenses (x) are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the (a) gross negligence, willful misconduct or bad faith of such Indemnitee or (b) a material breach of the obligations of such Indemnitee under the Loan Documents or (y) arises from any dispute solely among Indemnitees (other than claims against any Indemnitee in its capacity or in fulfilling its role as an Administrative Agent or arranger under this Agreement) other than as a result of any act or omission by either Borrower or any of their respective Affiliates. Neither Borrower shall, without the prior written consent of the relevant Indemnitee (which consent shall not be unreasonably withheld), effect any settlement of any pending or threatened investigation, litigation or proceeding against an Indemnitee in respect of which indemnity could have been sought hereunder by such Indemnitee unless (i) such settlement includes an unconditional release of such Indemnitee from all liability or claims that are the subject matter of such investigation, litigation or proceeding and (ii) does not include any statement as to any admission of fault. This Section 10.04(b) shall not apply with respect to Taxes other than any Taxes that represent losses, claims, damages, etc. arising from any non-Tax claim.

(c) Reimbursement by Lenders. To the extent that a Borrower for any reason fails to indefeasibly pay any amount required under Sections 10.04(a) or 10.04(b) to be paid by it to the Administrative Agent (or any sub-agent thereof), the L/C Issuer or any Related Party thereof, each Lender severally agrees to pay to the Administrative Agent (or any such sub-agent), the L/C Issuer or such Related Party, as the case may be, such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent (or any such sub-agent) or the L/C Issuer in its capacity as such, or against any Related Party of any of the foregoing acting for the Administrative Agent (or any such sub-agent) or L/C Issuer in connection with such capacity. The obligations of the Lenders under this Section 10.04(c) are subject to the provisions of Section 2.12(d).

(d) Waiver of Consequential Damages, Etc. To the fullest extent permitted by applicable Law, no party hereto may assert, and hereby waives, any claim against any Indemnitee, on any theory of liability (whether direct or indirect, in contract or tort or otherwise), for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan or Letter of Credit or the use of the proceeds thereof; provided that the foregoing shall not limit in any manner whatsoever the Borrowers’ indemnification obligations hereunder to the extent such damages are required to be indemnified against pursuant to Section 10.04(b). No Indemnitee referred to in Section 10.04(b) shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby, except for direct, actual damages, to the extent such damages are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence, bad faith or willful misconduct of such Indemnitee.

(e) Payments. All amounts due under this Section 10.04 shall be payable promptly after demand therefor.

(f) Survival. The agreements in this Section 10.04 shall survive the resignation of the Administrative Agent and the L/C Issuer, the replacement of any Lender, the termination of the Aggregate Commitments and the repayment, satisfaction or discharge of all the other Obligations.

10.05 Payments Set Aside. To the extent that any payment by or on behalf of the Borrowers is made to the Administrative Agent or any Lender or the Administrative Agent, the L/C Issuer 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 the Administrative Agent, the L/C Issuer 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 and the L/C Issuer severally agrees to pay to the Administrative Agent upon demand its applicable share (without duplication) of any amount so recovered from or repaid by the Administrative 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 Federal Funds Rate from time to time in effect. The obligation of the Lenders and the L/C Issuer under clause (b) of the preceding sentence shall survive the payment in full of the Obligations and the termination of this Agreement.

10.06 Successors and Assigns.

(a) Successors and Assigns Generally. 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 the Borrowers may not assign or otherwise transfer any of their rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of Section 10.06(b), (ii) by way of participation in accordance with the provisions of Section 10.06(d), or (iii) by way of pledge or assignment of a security interest subject to the restrictions of Section 10.06(f) (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 10.06(b) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the L/C Issuer and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Assignments by Lenders. Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans (including for purposes of this Section 10.06(b), participations in L/C Obligations and in Swing Line Loans) at the time owing to it); provided that any such assignment shall be subject to the following conditions:

(i) Minimum Amounts.

(A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

(B) in the case of any assignment not described in Section 10.06(b)(i)(A), the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment, determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date, shall not be less than $5,000,000 and $1,000,000 increments in excess thereof, unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Parent on behalf of itself and Gilead Ireland otherwise consents (each such consent not to be unreasonably withheld or delayed); provided, however, that concurrent assignments to members of an Assignee Group and concurrent assignments from members of an Assignee Group to a single Eligible Assignee (or to an Eligible Assignee and members of its Assignee Group) will be treated as a single assignment for purposes of determining whether such minimum amount has been met;

(ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loans or the Commitment assigned, except that this clause (ii) shall not apply to the Swing Line Lender’s rights and obligations in respect of Swing Line Loans;

(iii) Required Consents. No consent shall be required for any assignment except to the extent required by Section 10.06(b)(i) and, in addition:

(A) the consent of the Parent on behalf of itself and Gilead Ireland (such consent not to be unreasonably withheld or delayed) shall be required unless (1) an Event of Default has occurred and is continuing at the time of such assignment or (2) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund;

(B) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required for assignments in respect of any Commitment or, if the Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment, determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date, if such assignment is to a Person that is not a Lender with a Commitment in respect of the applicable facility, an Affiliate of such Lender or an Approved Fund with respect to such Lender;

(C) the consent of the L/C Issuer (such consent not to be unreasonably withheld or delayed) shall be required for any assignment that increases the obligation of the assignee to participate in exposure under one or more Letters of Credit (whether or not then outstanding); and

(D) the consent of the Swing Line Lender (such consent not to be unreasonably withheld or delayed) shall be required for any assignment.

(iv) Assignment and Assumption. The parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee payable by the assignor or assignee as agreed to between such parties in the amount of $3,500; provided, however, that the Administrative Agent may, in its sole discretion, elect to waive such processing and recordation fee in the case of any assignment. The assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

(v) No Assignment to Certain Persons. No such assignment shall be made (A) to the Borrowers or any of the Borrowers’ respective Affiliates or Subsidiaries or (B) to any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (B) or (C) to a natural person.

(vi) Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Parent and the Administrative Agent, the applicable pro rata share of Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent or any Lender hereunder (and interest accrued thereon) and (y) acquire (and fund as appropriate) its full pro rata share of all Loans and participations in Letters of Credit and Swing Line Loans in accordance with its Applicable Percentage. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable Law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to Section 10.06(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 and Section 10.04 with respect to facts and circumstances occurring prior to the effective date of such assignment. Upon request, each 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 Section 10.06(b) shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 10.06(d).

(c) Register. 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 Commitments of, and principal amounts (and stated interest) of the Loans and L/C Obligations 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 Administrative Agent 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. In addition, the Administrative Agent shall maintain on the Register information regarding the designation, and revocation of designation, of any Lender as a Defaulting Lender. The Register shall be available for inspection by the Borrowers and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrowers or the Administrative Agent, sell participations to any Person (other than a natural person, a Defaulting Lender or the Borrowers or any of the Borrowers’ Affiliates or Subsidiaries) (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 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 Administrative Agent, the Lenders and the L/C Issuer shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, waiver or other modification described in the first proviso to Section 10.01 that directly affects such Participant. Subject to Section 10.06(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 10.06(b). To the extent permitted by Law, each Participant also shall be entitled to the benefits of Section 10.08 as though it were a Lender; provided such Participant agrees to be subject to Section 2.13 as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrowers, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other rights or obligations under the Loan Documents (each such register, a “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of any Participant Register to any Person (including the identity of any Participant or any information relating to a Participant’s interest in any Loans made hereunder or other rights or obligations under any Loan Document) except to the extent that such disclosure is necessary to establish that such Loan or other right or obligation is in registered form under Section 5f.103-1(c) of the U.S. Treasury Regulations. The entries in a Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes hereunder notwithstanding any notice to the contrary.

(e) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Section 3.01 or Section 3.04 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 Borrowers’ prior written consent. A Participant that would be a Foreign Lender if it were a Lender 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 such Borrower, to comply with Section 3.01(e) as though it were a Lender.

(f) Certain Pledges. 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.

(g) Electronic Execution of Assignments. The words “execution,” “signed,” “signature,” and words of like import in any Assignment and Assumption shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable Law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state Laws based on the Uniform Electronic Transactions Act.

(h) Resignation as L/C Issuer or Swing Line Lender after Assignment. Notwithstanding anything to the contrary contained herein, if at any time Bank of America assigns all of its Commitment and Loans pursuant to Section 10.06(b), Bank of America may, (i) upon 30 days’ notice to the Borrowers and the Lenders, resign as L/C Issuer and/or (ii) upon 30 days’ notice to the Borrowers, resign as Swing Line Lender. In the event of any such resignation as L/C Issuer or Swing Line Lender, the Borrowers shall be entitled to appoint from among the Lenders a successor L/C Issuer or Swing Line Lender hereunder; provided, however, that no failure by the Borrowers to appoint any such successor shall affect the resignation of Bank of America as L/C Issuer or Swing Line Lender, as the case may be. If Bank of America resigns as L/C Issuer, it shall retain all the rights, powers, privileges and duties of the L/C Issuer hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as 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 Bank of America 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). Upon the appointment of a successor L/C Issuer and/or Swing Line Lender, (a) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring L/C Issuer or Swing Line Lender, as the case may be, and (b) the successor L/C Issuer shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to Bank of America to effectively assume the obligations of Bank of America with respect to such Letters of Credit.

10.07 Treatment of Certain Information; Confidentiality. Each of the Administrative Agent, the Lenders and the L/C Issuer agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its and its Affiliates’ respective partners, directors, officers, employees, agents, advisors and representatives (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority purporting to have jurisdiction over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners) or required by applicable Law or regulations or by any subpoena or similar legal process (in which case the Administrative Agent and the Lenders agree to inform the Borrowers promptly thereof (unless prohibited by law, rule or regulation and except in connection with any order or request as part of a regulatory examination or other regulatory request)), (c) to any other party hereto, (d) 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, (e) subject to an agreement containing provisions not less restrictive than those of this Section 10.07, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrowers and their respective obligations, (f) with the prior written consent of the Borrowers or (g) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section 10.07 or (y) becomes available to the Administrative Agent, any Lender, the L/C Issuer or any of their respective Affiliates on a nonconfidential basis from a source other than the Borrowers or any of their Subsidiaries or Affiliates.

For purposes of this Section 10.07, “Information” means all information received from either Borrower or any Subsidiary relating to such Borrower or any Subsidiary or any of their respective businesses, other than any such information that is available to the Administrative Agent, any Lender or the L/C Issuer on a nonconfidential basis prior to disclosure by either Borrower or any Subsidiary. Any Person required to maintain the confidentiality of Information as provided in this Section 10.07 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

Each of the Administrative Agent, the Lenders and the L/C Issuer acknowledges that (a) the Information may include material non-public information concerning the Borrowers or any of their Subsidiaries, (b) it has developed compliance procedures regarding the use of material non-public information and (c) it will handle such material non-public information in accordance with applicable Law, including Federal and state securities Laws.

10.08 Right of Setoff. If an Event of Default under Section 8.01(a) or an acceleration of the Loans shall have occurred and be continuing with respect to a Borrower, each Lender, the L/C Issuer and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable Law, to setoff and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) of such Borrower at any time held and other obligations (in whatever currency) at any time owing by such Lender, the L/C Issuer or any such Affiliate to or for the credit or the account of such Borrower against any and all of the obligations of such Borrower now or hereafter existing under this Agreement or any other Loan Document to such Lender or the L/C Issuer, irrespective of whether or not such Lender or the L/C Issuer shall have made any demand under this Agreement or any other Loan Document and although such obligations of such Borrower may be contingent or unmatured or are owed to a branch or office of such Lender or the L/C Issuer different from the branch or office holding such deposit or obligated on such indebtedness; provided, that in the event that any Defaulting Lender shall exercise any such right of setoff, (x) all amounts so set off shall be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Section 2.15 and, pending such payment, shall be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Administrative Agent and the Lenders, and (y) the Defaulting Lender shall provide promptly to the Administrative Agent a statement describing in reasonable detail the Obligations owing to such Defaulting Lender as to which it exercised such right of setoff. The rights of each Lender and their respective Affiliates under this Section 10.08 are in addition to other rights and remedies (including other rights of setoff) that such Lender, the L/C Issuer or their respective Affiliates may have. Each Lender and the L/C Issuer agrees to notify the Borrower and the Administrative Agent promptly after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such setoff and application.

10.09 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 the Administrative 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 applicable Borrower. In determining whether the interest contracted for, charged, or received by the Administrative 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.

10.10 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and the other Loan Documents constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

10.11 Survival of Representations and Warranties. All representations and warranties made hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or in connection herewith or therewith shall survive the execution and delivery hereof and thereof. Such representations and warranties have been or will be relied upon by the Administrative Agent and each Lender, regardless of any investigation made by the Administrative Agent or any Lender or on their behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default at the time of any Credit Extension, and shall continue in full force and effect as long as any Loan or any other Obligation hereunder shall remain unpaid or unsatisfied or any Letter of Credit shall remain outstanding.

10.12 Severability. If any provision of this Agreement or the other Loan Documents is held to be illegal, invalid or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this Agreement and the other Loan Documents shall not be affected or impaired thereby and (b) the parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions. The invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. Without limiting the foregoing provisions of this Section 10.02, if and to the extent that the enforceability of any provisions in this Agreement relating to Defaulting Lenders shall be limited by Debtor Relief Laws, as determined in good faith by the Administrative Agent, the L/C Issuer or the Swing Line Lender, as applicable, then such provisions shall be deemed to be in effect only to the extent not so limited.

10.13 Replacement of Lenders. If any Lender requests compensation under Section 3.04, or if a Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.01, or if any Lender is a Defaulting Lender, then the Borrowers may, at their sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 10.06), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that:

(a) each Borrower shall have paid to the Administrative Agent fifty percent (50%) of the assignment fee specified in Section 10.06(b)(iv);

(b) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and L/C Advances, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 3.01, Section 3.04 or Section 3.05) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrowers (in the case of all other amounts);

(c) in the case of any such assignment resulting from a claim for compensation under Section 3.04 or payments required to be made pursuant to Section 3.01, such assignment will result in a reduction in such compensation or payments thereafter; and

(d) such assignment does not conflict with applicable Laws.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrowers to require such assignment and delegation cease to apply.

If the amount of the Agreement Currency so purchased is greater than the sum originally due to the Administrative Agent or any Lender in such currency, the

Administrative Agent or such Lender, as the case may be, agrees to return the amount of any excess to such Borrower (or to any other Person who may be entitled thereto under applicable law).

Without limiting the generality of the foregoing, Guarantor’s Obligations hereunder shall extend to all amounts that constitute part of the Guaranteed Obligations that would be owed by the Borrower to any Credit Party under or in respect of the Loan Documents but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving the Borrower.

Section 2.02 Guaranty Absolute. Guarantor guarantees that the Guaranteed Obligations will be paid strictly in accordance with the terms of the Loan Documents, to the fullest extent permitted by Law now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of any Credit Party with respect thereto. The Obligations of Guarantor under or in respect of this Agreement are independent of the Guaranteed Obligations, and a separate action or actions may be brought and prosecuted against Guarantor to enforce this Agreement, irrespective of whether any action is brought against the Borrower or whether the Borrower is joined in any such action or actions.

(c) any taking, release, subordination or amendment or waiver of, or consent to departure from, any other guarantee (if any), for all or any of the Guaranteed Obligations;

F-3

(d) any change, restructuring or termination of the corporate structure or existence of the Parent or any of its Subsidiaries or any insolvency, bankruptcy, reorganization or other similar proceeding under Debtor Relief Laws affecting the Parent, the Borrower or their assets or any resulting release or discharge of any Guaranteed Obligation;

(e) the existence of any claim, setoff or other right which Guarantor may have at any time against the Borrower, the Administrative Agent, any Lender or any other Person, whether in connection herewith or any unrelated transaction;

(f) any provision of applicable Law purporting to prohibit the payment or performance by the Parent or the Borrower of any of the Obligations of such Person;

(g) any failure of any Credit Party to disclose to the Parent or the Borrower any information relating to the business, financial condition, operations, performance, properties or prospects of the Parent or the Borrower now or hereafter known to such Credit Party (Guarantor waives any duty on the part of the Credit Parties to disclose such information);

(h) the failure of any other Person to execute or deliver any other guarantee or agreement or the release or reduction of liability of Guarantor or other guarantor (if any) or surety (if any) with respect to the Guaranteed Obligations; or

(i) any other circumstance (including, without limitation, any statute of limitations) or any existence of or reliance on any representation by any Credit Party that might otherwise constitute a legal or equitable discharge or defense available to, or a discharge of, the Parent, the Borrower or any other guarantor or surety.

(a) Guarantor hereby unconditionally and irrevocably waives, to the extent permitted by applicable Law, promptness, diligence, notice of acceptance, presentment, demand for performance, notice of nonperformance, default, acceleration, protest or dishonor and any other notice with respect to any of the Guaranteed Obligations and this Agreement and any requirement that any Credit Party protect, secure, perfect or insure any Lien or any property subject thereto or exhaust any right or take any action against the Borrower or any other Person.

(e) Guarantor acknowledges that it will receive substantial direct and indirect benefits from the financing arrangements contemplated by the Loan Documents and that the waivers set forth in Section 2.02 and this Section 2.03 are knowingly made in contemplation of such benefits.

Section 2.04 Subordination. (a) Guarantor hereby unconditionally and irrevocably agrees not to exercise any rights that it may now have or hereafter acquire against the Borrower or any other insider guarantor (if any) that arise from the existence, payment, performance or enforcement of Guarantor’s Obligations under or in respect of this Agreement or any other Loan Document, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution (pursuant to Section 2.01(c) or otherwise) or indemnification and any right to participate in any claim or remedy of any Credit Party against the Borrower, Guarantor or any other insider guarantor (if any) whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from the Borrower or any other insider guarantor (if any), directly or indirectly, in cash or other property or by setoff or in any other manner, payment or security on account of such claim, remedy or right without the prior written consent of the Administrative Agent, unless and until the Termination Date has occurred.

(b) Guarantor hereby agrees that any and all debts, liabilities and other obligations owed to it by the Borrower, including pursuant to Section 2.01(c) (collectively, the “Subordinated Obligations”), are hereby subordinated to the prior payment in full in cash of the Obligations of the Borrower under the Loan Documents to the extent and in the manner hereinafter set forth in this Section 2.04(b):

(A) Except during the continuance of an Event of Default (including the commencement and continuation of any proceeding under any Debtor Relief Law relating to the Borrower), Guarantor may receive regularly scheduled payments from the Borrower on account of the Subordinated Obligations. After the occurrence and during the continuance of any Event of Default (including the commencement and continuation of any proceeding under any Debtor Relief Law relating to the Borrower), however, unless the Administrative Agent otherwise agrees in writing, Guarantor shall not demand, accept or take any action to collect any payment on account of the Subordinated Obligations.

(B) In any proceeding under any Debtor Relief Law relating to the Borrower, Guarantor agrees that, unless the Administrative Agent otherwise agrees in writing, the Credit Parties shall be entitled to receive payment in full in cash of all Obligations (including all interest and expenses accruing after the commencement of a proceeding under any Debtor Relief Law, whether or not constituting an allowed claim in such proceeding (“Post Petition Interest”)) of the Borrower before Guarantor receives payment of any Subordinated Obligations of the Borrower.

F-5

(C) After the occurrence and during the continuance of any Event of Default (including the commencement and continuation of any proceeding under any Debtor Relief Law relating to the Borrower), Guarantor shall, if the Administrative Agent so requests, collect, enforce and receive payments on account of any Subordinated Obligations due to Guarantor from the Borrower as trustee for the Credit Parties and deliver such payments to the Administrative Agent for application to the Guaranteed Obligations (including all Post Petition Interest), together with any necessary endorsements or other instruments of transfer, but without reducing or affecting in any manner the liability of Guarantor under the other provisions of this Agreement.

(D) After the occurrence and during the continuance of any Event of Default (including the commencement and continuation of any proceeding under any Debtor Relief Law relating to the Borrower), the Administrative Agent is authorized and empowered (but without any obligation to so do), in its discretion, (A) in the name of Guarantor, to collect and enforce, and to submit claims in respect of, Subordinated Obligations due to Guarantor and to apply any amounts received thereon to the Guaranteed Obligations (including any and all Post Petition Interest), and (B) to require Guarantor (1) to collect and enforce, and to submit claims in respect of, Subordinated Obligations due to Guarantor and (2) to pay any amounts received on such obligations to the Administrative Agent for application to the Guaranteed Obligations (including any and all Post Petition Interest).

(c) If any amount shall be paid to Guarantor in violation of this Section 2.04 at any time prior to the Termination Date, such amount shall be received and held in trust for the benefit of the Credit Parties, shall be segregated from other property and funds of Guarantor and shall forthwith be paid or delivered to the Administrative Agent in the same form as so received (with any necessary endorsement or assignment) to be credited and applied to the Guaranteed Obligations and all other amounts payable under this Agreement, whether matured or unmatured, in accordance with the terms of the Loan Documents.

(d) If the Termination Date shall have occurred, the Administrative Agent will, at Guarantor’s request and expense, execute and deliver to Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to Guarantor of an interest in the Guaranteed Obligations resulting from any payment made by Guarantor pursuant to this Agreement.

Section 2.05 Payments Free and Clear of Taxes, Etc. (a) Any and all payments made by or on account of Guarantor under or in respect of this Agreement or any other Loan Document shall be made, in accordance with Section 3.01 of the Credit Agreement, free and clear of and without deduction or withholding for any Indemnified Taxes (including Other Taxes); provided that if any Indemnified Taxes (including Other Taxes) are required by applicable Law to be withheld or deducted from such payments, then (i) the sum payable by Guarantor shall be increased as necessary so that after making all required deductions or withholdings (including deductions or withholdings applicable to additional sums payable under this Section 2.05), each of the Administrative Agent or applicable Lender, as the case may be, receives an amount equal to the sum it would have received had no such deductions or withholdings been required to be made, (ii) Guarantor shall make such deductions or withholdings as required by Law and (iii) Guarantor shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable Law.

F-6

(b) Without limiting the provisions of subsection (a) above, Guarantor shall timely pay any Other Taxes that arise from any payment made by or on behalf of Guarantor under or in respect of this Agreement or from the execution, delivery, performance, enforcement or registration of, or otherwise with respect to, this Agreement to the relevant Governmental Authority in accordance with applicable Law.

(c) Guarantor shall indemnify the Administrative Agent and each Lender within ten days after demand therefor, for the full amount of Indemnified Taxes or Other Taxes (including any Indemnified Taxes or Other Taxes imposed or asserted or attributable to amounts payable under this Section 2.05) paid by the Administrative Agent or such Lender, as the case may be, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate setting forth in reasonable detail the basis for and calculation of the amount of such payment or liability delivered to Guarantor by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

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

(d) Without prejudice to the survival of any of the other agreements of Guarantor under this Agreement or any of the other Loan Documents, the agreements and obligations of Guarantor contained in Section 2.01(a) (with respect to enforcement expenses), the last sentence of Section 2.02, Section 2.05 and this Section 5.04 shall survive the payment in full of the Guaranteed Obligations and all of the other amounts payable under this Agreement.

G-1

(iii) the Company has not, does not intend to, and does not believe (nor should it reasonably believe) that it will, incur debts or liabilities beyond the Company’s ability to pay such debts and liabilities as they become due (whether at maturity or otherwise);

(iv) the Company does not have unreasonably small capital with which to conduct the businesses in which it is engaged as such businesses are now conducted (and reflected in the Projections) and are proposed to be conducted following the Tender Offer Closing Date; and

(v) the Company is “solvent” within the meaning given to that term and similar terms under the Bankruptcy Code and applicable laws relating to fraudulent transfers and conveyances.

G-2

IN WITNESS WHEREOF, the undersigned has executed this Solvency Certificate as of the date first above written, solely in his/her capacity as the Chief Financial Officer of the Borrower and not in his/her individual capacity.
