To the extent the terms of this Agreement and the Sweep Documentation conflict, the terms of this Agreement shall control.

(b) Swing Loan Refunding. The Swing Line Lender may at any time, in its sole and absolute discretion, direct that the Swing Loans owing to it be refunded by delivering a notice to such effect to the Administrative Agent, specifying the aggregate principal amount thereof (a “Notice of Swing Loan Refunding”). Promptly upon receipt of a Notice of Swing Loan Refunding, the Administrative Agent shall give notice of the contents thereof to the Lenders with Revolving A Commitments and, unless an Event of Default specified in Section 8.01(h) in respect of the Borrowers have occurred, the Borrower Representative. Each such Notice of Swing Loan Refunding shall be deemed to constitute delivery by the Borrower Representative of a Notice of Borrowing requesting Revolving A Loans consisting of Base Rate Loans in the amount of the Swing Loans to which it relates. Each Lender with a Revolving A Commitment (including the Swing Line Lender) hereby unconditionally agrees (notwithstanding that any of the conditions specified in Section 4.02 or elsewhere in this Agreement shall not have been satisfied, but subject to the provisions of paragraph (d) below) to make a Revolving A Loan to the Borrowers in the amount of such Lender’s Revolving A Facility Percentage of the aggregate amount of the Swing Loans to which such Notice of Swing Loan Refunding relates. Each such Lender shall make the amount of such Revolving A Loan available to the Administrative Agent in immediately available funds at the Payment Office not later than 2:00 P.M. (local time at the Payment Office), if such notice is received by such Lender prior to 11:00 A.M. (local time at its domestic lending office), or not later than 2:00 P.M. (local time at the Payment Office) on the next Business Day, if such notice is received by such Lender after such time. The proceeds of such Revolving A Loans shall be made immediately available to the Swing Line Lender and applied by it to repay the principal amount of the Swing Loans to which such Notice of Swing Loan Refunding relates.

(c) Swing Loan Participation. If prior to the time a Revolving A Loan would otherwise have been made as provided above as a consequence of a Notice of Swing Loan

Refunding, any of the events specified in Section 8.01(h) shall have occurred in respect of the Borrowers or one or more of the Lenders with Revolving A Commitments shall determine that it is legally prohibited from making a Revolving A Loan under such circumstances, each Lender (other than the Swing Line Lender), or each Lender (other than such Swing Line Lender) so prohibited, as the case may be, shall, on the date such Revolving A Loan would have been made by it (the “Purchase Date”), purchase an undivided participating interest (a “Swing Loan Participation”) in the outstanding Swing Loans to which such Notice of Swing Loan Refunding relates, in an amount (the “Swing Loan Participation Amount”) equal to such Lender’s Revolving A Facility Percentage of such outstanding Swing Loans. On the Purchase Date, each such Lender or each such Lender so prohibited, as the case may be, shall pay to the Swing Line Lender, in immediately available funds, such Lender’s Swing Loan Participation Amount, and promptly upon receipt thereof the Swing Line Lender shall, if requested by such other Lender, deliver to such Lender a participation certificate, dated the date of the Swing Line Lender’s receipt of the funds from, and evidencing such Lender’s Swing Loan Participation in, such Swing Loans and its Swing Loan Participation Amount in respect thereof. If any amount required to be paid by a Lender to the Swing Line Lender pursuant to the above provisions in respect of any Swing Loan Participation is not paid on the date such payment is due, such Lender shall pay to the Swing Line Lender on demand interest on the amount not so paid at the overnight Federal Funds Effective Rate from the due date until such amount is paid in full. Whenever, at any time after the Swing Line Lender has received from any other Lender such Lender’s Swing Loan Participation Amount, the Swing Line Lender receives any payment from or on behalf of the Borrowers on account of the related Swing Loans, the Swing Line Lender will promptly distribute to such Lender its ratable share of such amount based on its Revolving A Facility Percentage of such amount on such date on account of its Swing Loan Participation (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s participating interest was outstanding and funded); provided, however, that if such payment received by the Swing Line Lender is required to be returned, such Lender will return to the Swing Line Lender any portion thereof previously distributed to it by the Swing Line Lender.

(d) Obligations Unconditional. Each Lender’s obligation to make Revolving A Loans pursuant to Section 2.04(b) and/or to purchase Swing Loan Participations in connection with a Notice of Swing Loan Refunding shall be subject to the conditions that (i) such Lender shall have received a Notice of Swing Loan Refunding complying with the provisions hereof and (ii) at the time the Swing Loans that are the subject of such Notice of Swing Loan Refunding were made, the Swing Line Lender making the same had no actual written notice from another Lender that an Event of Default had occurred and was continuing, but otherwise shall be absolute and unconditional, shall be solely for the benefit of the Swing Line Lender that gives such Notice of Swing Loan Refunding, and shall not be affected by any circumstance, including, without limitation, (A) any set-off, counterclaim, recoupment, defense or other right that such Lender may have against any other Lender, any Loan Party, or any other Person, or any Loan Party may have against any Lender or other Person, as the case may be, for any reason whatsoever, (B) the occurrence or continuance of a Default or Event of Default, (C) any event or circumstance involving a Material Adverse Effect, (D) any breach of any Loan Document by any party thereto, or (E) any other circumstance, happening or event, whether or not similar to any of the foregoing.”

Subject to Section 2.05(c) below, each Letter of Credit shall have an expiry date (including any renewal periods) occurring not later than the earlier of (y) one year from the date of issuance thereof, or (z) 30 Business Days prior to the Revolving Facility Termination Date.

(b) LC Requests. Whenever the Borrowers desire that a Letter of Credit be issued for its account or the account of any eligible LC Obligor, the Borrower Representative shall give the Administrative Agent and the applicable LC Issuer written or telephonic notice (in the case of telephonic notice, promptly confirmed in writing if so requested by the Administrative Agent) which, if in the form of written notice, shall be substantially in the form of Exhibit B-3 (each such request, a “LC Request”), or transmit by electronic communication (if arrangements for doing so have been approved by the applicable LC Issuer), prior to 11:00 A.M. (local time at the Notice Office) at least three Business Days (or such shorter period as may be acceptable to the relevant LC Issuer) prior to the proposed date of issuance (which shall be a Business Day), which LC Request shall include such supporting documents that such LC Issuer customarily requires in connection therewith (including, in the case of a Letter of Credit for an account party other than a Borrower, an application for, and if applicable a reimbursement agreement with respect to, such Letter of Credit). In the event of any inconsistency between any of the terms or provisions of any LC Document and the terms and provisions of this Agreement respecting Letters of Credit, the terms and provisions of this Agreement shall control.

(c) Auto-Renewal Letters of Credit. If an LC Obligor so requests in any applicable LC Request, each LC Issuer shall agree to issue a Letter of Credit that has automatic renewal provisions; provided, however, that any Letter of Credit that has automatic renewal provisions must permit such LC Issuer to prevent any such renewal at least once in each twelve-month period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not later than a day in each such twelve-month period to be agreed upon at the time such Letter of Credit is issued. Once any such Letter of Credit that has automatic renewal provisions has been issued, the Lenders shall be deemed to have authorized (but may not require) such LC Issuer to permit the renewal of such Letter of Credit at any time to an expiry date not later than 30 Business Days prior to the Revolving Facility Termination Date; provided, however, that such LC Issuer shall not permit any such renewal if (i) such LC Issuer has determined that it would have no obligation at such time to issue such Letter of Credit in its renewed form under the terms hereof, or (ii) it has received notice (which may be by telephone or in writing) on or before the day that is two Business Days before the date that such LC Issuer is permitted to send a notice of non-renewal from the Administrative Agent, any Lender or the Borrower Representative that one or more of the applicable conditions specified in Section 4.02 is not then satisfied.

(d) Applicability of ISP98 and UCP. Unless otherwise expressly agreed by the applicable LC Issuer and the applicable LC Obligor, when a Letter of Credit is issued, (i) the rules of the “International Standby Practices 1998” published by the Institute of International Banking Law & Practice (or such later version thereof as may be in effect at the time of issuance) shall apply to each Standby Letter of Credit, and (ii) the rules of the Uniform Customs and Practice for Documentary Credits, as most recently published by the International Chamber of Commerce at the time of issuance (including the International Chamber of Commerce’s decision published by the Commission on Banking Technique and Practice on April 6, 1998 regarding the European single currency (euro)) shall apply to each Commercial Letter of Credit.

(e) Notice of LC Issuance. Each LC Issuer shall, on the date of each LC Issuance by it, give the Administrative Agent, each applicable Lender and the Borrower Representative written notice of such LC Issuance, accompanied by a copy to the Administrative Agent of the Letter of Credit or Letters of Credit issued by it. Each LC Issuer shall provide to the Administrative Agent a quarterly (or monthly if requested by any applicable Lender) summary describing each Letter of Credit issued by such LC Issuer and then outstanding and an identification for the relevant period of the daily aggregate LC Outstandings represented by Letters of Credit issued by such LC Issuer.

(f) Reimbursement Obligations.

(i) The Borrowers hereby agree to reimburse (or cause any LC Obligor for whose account a Letter of Credit was issued to reimburse) each LC Issuer, by making payment directly to such LC Issuer in immediately available funds at the payment office of such LC Issuer, for any Unpaid Drawing with respect to any Letter of Credit immediately after, and in any event on the date on which, such LC Issuer notifies the Borrower Representative (or any such other LC Obligor for whose account such Letter of Credit was issued) of such payment or disbursement (which notice to the Borrower Representative (or such other LC Obligor) shall be delivered reasonably promptly after any such payment or disbursement), such payment to be made in Dollars, with interest on the amount so paid or disbursed by such LC Issuer, to the extent not reimbursed prior to 1:00 P.M. (local time at the payment office of the applicable LC Issuer) on the date of such payment or disbursement, from and including the date paid or disbursed to but not including the date such LC Issuer is reimbursed therefor at a rate per annum that shall be the rate then applicable to Revolving A Loans pursuant to Section 2.09(a)(i) that are Base Rate Loans or, if not reimbursed on the date of such payment or disbursement, at the Default Rate, any such interest also to be payable on demand. If by 11:00 A.M. on the Business Day immediately following notice to it of its obligation to make reimbursement in respect of an Unpaid Drawing, the Borrower Representative or the relevant LC Obligor has not made such reimbursement out of its available cash on hand or, in the case of a Borrower, a contemporaneous Borrowing of Revolving A Loans hereunder (if such Borrowing is otherwise available to the Borrowers), (x) the Borrower Representative will in each case be deemed to have given a Notice of Borrowing for Revolving A Loans that are Base Rate Loans in an aggregate principal amount sufficient to reimburse such Unpaid Drawing (and the Administrative Agent shall promptly give notice to the Lenders of such deemed Notice of Borrowing), (y) the Lenders shall, unless they are legally prohibited from doing so, make the Revolving A Loans contemplated by such deemed Notice of Borrowing (which Revolving A Loans shall be considered made under Section 2.02(a)), and (z) the proceeds of such Revolving A Loans shall be disbursed directly to the applicable LC Issuer to the extent necessary to effect such reimbursement and repayment of the Unpaid Drawing, with any excess proceeds to be made available to the Borrowers in accordance with the applicable provisions of this Agreement.

(ii) Obligations Absolute. Each LC Obligor’s obligation under this Section to reimburse each LC Issuer with respect to Unpaid Drawings (including, in each case, interest thereon) shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment that such LC Obligor may have or have had against such LC Issuer, the Administrative Agent or any Lender, including, without limitation, any defense based upon the failure of any drawing under a Letter of Credit to conform to the terms of the Letter of Credit or any non-application or misapplication by the beneficiary of the proceeds of such drawing; provided, however, that no LC Obligor shall be obligated to reimburse an LC Issuer for any wrongful payment made by such LC Issuer under a Letter of Credit as a result of acts or omissions constituting willful misconduct or gross negligence on the part of such LC Issuer.

(g) LC Participations.

(i) Immediately upon each LC Issuance, the LC Issuer of such Letter of Credit shall be deemed to have sold and transferred to each Lender with a Revolving A Commitment, and each such Lender (each an “LC Participant”) shall be deemed irrevocably and unconditionally to have purchased and received from such LC Issuer, without recourse or warranty, an undivided interest and participation (an “LC Participation”), to the extent of such Lender’s Revolving A Facility Percentage of the Stated Amount of such Letter of Credit in effect at such time of issuance, in such Letter of Credit, each substitute Letter of Credit, each drawing made thereunder, the obligations of any LC Obligor under this Agreement with respect thereto (although LC Fees relating thereto shall be payable directly to the Administrative Agent for the account of the Lenders as provided in Section 2.11 and the LC Participants shall have no right to receive any portion of any fees of the nature contemplated by Section 2.11(c) or Section 2.11(e)), the obligations of any LC Obligor under any LC Documents pertaining thereto, and any security for, or guaranty pertaining to, any of the foregoing.

(ii) In determining whether to pay under any Letter of Credit, an LC Issuer shall not have any obligation relative to the LC Participants other than to determine that any documents required to be delivered under such Letter of Credit have been delivered and that they appear to comply on their face with the requirements of such Letter of Credit. Any action taken or omitted to be taken by an LC Issuer under or in connection with any Letter of Credit, if taken or omitted in the absence of gross negligence or willful misconduct, shall not create for such LC Issuer any resulting liability.

(iii) If an LC Issuer makes any payment under any Letter of Credit and the applicable LC Obligor shall not have reimbursed such amount in full to such LC Issuer pursuant to Section 2.05(f), such LC Issuer shall promptly notify the Administrative Agent, and the Administrative Agent shall promptly notify each LC Participant of such failure, and each LC Participant shall promptly and unconditionally pay to the Administrative Agent for the account of such LC Issuer, the amount of such LC Participant’s Revolving A Facility Percentage of such payment in Dollars and in same-day funds; provided, however, that no LC Participant shall be obligated to pay to the Administrative Agent its Revolving A Facility Percentage of such unreimbursed amount for any wrongful payment made by such LC Issuer under a Letter of Credit as a result of acts or omissions constituting willful misconduct or gross negligence on the part of such LC Issuer. If the Administrative Agent so notifies any LC Participant required to fund a payment under a Letter of Credit prior to 11:00 A.M. (local time at its Notice Office) on any Business Day, such LC Participant shall make available to the Administrative Agent for the account of the relevant LC Issuer such LC Participant’s Revolving A Facility Percentage of the amount of such payment on such Business Day in same-day funds. If and to the extent such LC Participant shall not have

so made its Revolving A Facility Percentage of the amount of such payment available to the Administrative Agent for the account of the relevant LC Issuer, such LC Participant agrees to pay to the Administrative Agent for the account of such LC Issuer, forthwith on demand, such amount, together with interest thereon, for each day from such date until the date such amount is paid to the Administrative Agent for the account of such LC Issuer at the Federal Funds Effective Rate. The failure of any LC Participant to make available to the Administrative Agent for the account of the relevant LC Issuer its Revolving A Facility Percentage of any payment under any Letter of Credit shall not relieve any other LC Participant of its obligation hereunder to make available to the Administrative Agent for the account of such LC Issuer its Revolving A Facility Percentage of any payment under any Letter of Credit on the date required, as specified above, but no LC Participant shall be responsible for the failure of any other LC Participant to make available to the Administrative Agent for the account of such LC Issuer such other LC Participant’s Revolving A Facility Percentage of any such payment.

(iv) Whenever an LC Issuer receives a payment of a reimbursement obligation as to which the Administrative Agent has received for the account of such LC Issuer any payments from the LC Participants pursuant to subpart (iii) above, such LC Issuer shall pay to the Administrative Agent and the Administrative Agent shall promptly pay to each LC Participant that has paid its Revolving A Facility Percentage thereof, in same-day funds, an amount equal to such LC Participant’s Revolving A Facility Percentage of the principal amount thereof and interest thereon accruing after the purchase of the respective LC Participations, as and to the extent so received.

(v) The obligations of the LC Participants to make payments to the Administrative Agent for the account of each LC Issuer with respect to Letters of Credit shall be irrevocable and not subject to counterclaim, set-off or other defense or any other qualification or exception whatsoever and shall be made in accordance with the terms and conditions of this Agreement under all circumstances, including, without limitation, any of the following circumstances:

(A) any lack of validity or enforceability of this Agreement or any of the other Loan Documents;

(B) the existence of any claim, set-off defense or other right that any LC Obligor may have at any time against a beneficiary named in a Letter of Credit, any transferee of any Letter of Credit (or any Person for whom any such transferee may be acting), the Administrative Agent, any LC Issuer, any Lender, or other Person, whether in connection with this Agreement, any Letter of Credit, the transactions contemplated herein or any unrelated transactions (including any underlying transaction between the applicable LC Obligor and the beneficiary named in any such Letter of Credit), other than any claim that the applicable LC Obligor may have against any applicable LC Issuer for gross negligence or willful misconduct of such LC Issuer in making payment under any applicable Letter of Credit;

(C) any draft, certificate or other document presented under the 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;

(D) the surrender or impairment of any security for the performance or observance of any of the terms of any of the Loan Documents; or

(E) the occurrence of any Default or Event of Default.

(vi) To the extent any LC Issuer is not indemnified by the Borrowers or any LC Obligor, the LC Participants will reimburse and indemnify such LC Issuer, in proportion to their respective Revolving A Facility Percentages, for and against any and all liabilities, obligations, losses, damages, penalties, claims, actions, judgments, costs, expenses or disbursements of whatsoever kind or nature that may be imposed on, asserted against or incurred by such LC Issuer in performing its respective duties in any way related to or arising out of LC Issuances by it; provided, however, that no LC Participants shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, claims, actions, judgments, costs, expenses or disbursements resulting from such LC Issuer’s gross negligence or willful misconduct.”
