(iv) such Letter of Credit is in form and substance acceptable to the Issuing Bank in its reasonable discretion;

(v) the Borrower has delivered to the Issuing Bank a completed and executed Letter of Credit Application and a completed Letter of Credit Request; and

(vi) such Letter of Credit is governed by the Uniform Customs and Practice for Documentary Credits (1993 Revision), International Chamber of Commerce Publication No. 500 or any successor to such publication. If the terms of any letter of credit application referred to in the foregoing clause (iv) conflicts with the terms of this Agreement, the terms of this Agreement shall control.

(b) Participations. Upon the date of any Issuance Event (including in the case of each Existing Letter of Credit, the deemed Issuance Event with respect thereto on the Closing Date), the Issuing Bank shall be deemed to have sold to each other Participant and each other Participant shall have been deemed to have purchased from the Issuing Bank a participation in the related Letter of Credit Obligations equal to such Participant’s Pro Rata Share at such date. In consideration and in furtherance of the foregoing, each Participant hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of the Issuing Bank, such Participant’s Pro Rata Share of each LC Disbursement pursuant to a Letter of Credit and not reimbursed by the Borrower (or, if applicable, another party pursuant to its obligations under any other Loan Document) forthwith on the date due as provided in Section 2.01(c). Each Participant acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of a Default or an Event of Default, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. The Issuing Bank shall promptly notify the Administrative

Agent upon receipt of any Letter of Credit Request and shall promptly deliver to the Administrative Agent copies of any such request together with copies of drafts (followed up by copies of the original) of the Letter of Credit or proposed Letter of Credit subject thereto. The Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Issuing Bank shall as promptly as possible give telephonic notification, confirmed by fax, to the Administrative Agent and the Borrower of such demand for payment and whether the Issuing Bank has made or will make disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank and the Participants with respect to any such LC Disbursement. The Administrative Agent shall promptly give each Participant notice thereof.

(c) Reimbursement. The Borrower hereby agrees to pay on demand to the Issuing Bank in respect of each Letter of Credit issued for its account an amount equal to any LC Disbursement in respect of such Letter of Credit. In the event the Issuing Bank makes a LC Disbursement pursuant to a request for draw presented under a Letter of Credit and such LC Disbursement is not promptly reimbursed by the Borrower on the next Business Day, the Issuing Bank shall give notice of such failure to pay to the Administrative Agent and the Participants, and each Participant shall promptly reimburse the Issuing Bank for such Participant’s Pro Rata Share of such LC Disbursement, and, in satisfaction of that obligation, hereby irrevocably authorizes the Administrative Agent to withdraw a portion of its Deposits in an amount equal to such Participant’s Pro Rata Share of such LC Disbursement and pay the same over to the Administrative Agent, and such reimbursement shall be deemed for all purposes of this Agreement to constitute a Borrowing comprised of Base Rate LC Advances to the Borrower from such Participant. The Deposit Bank hereby agrees to effect the withdrawal referred to in the immediately preceding sentence and all other withdrawals and payments requested by the Administrative Agent pursuant to, and in accordance with, the terms of this Agreement. The Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the Administrative Agent and the Participants to record and otherwise treat such payment under a Letter of Credit not immediately reimbursed by the Borrower as a Borrowing comprised of Base Rate LC Advances; provided that if the Acceleration Date shall have occurred prior to the reimbursement pursuant to this Section 2.01(c) of any LC Disbursement made, then no LC Advance shall be deemed to have been made and the Borrower will not be relieved of its Reimbursement Obligations with respect to such LC Disbursement. Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to this paragraph, the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that Participants have made payments pursuant to this paragraph to reimburse the Issuing Bank for LC Disbursement, then to such Participants and the Issuing Bank as their interests may appear (it being understood and agreed that any such payment to be made pursuant to this Section 2.01(c) to a Participant shall be made to the Administrative Agent for the account of such Participant and paid over to the Deposit Bank for deposit in the Deposit Account). In the event that any Reimbursement Obligation is not satisfied on the date on which the applicable LC Disbursement was made, the Borrower shall pay interest on the unpaid amount of such Reimbursement Obligation (i) if the Acceleration Date shall have occurred, at the rate payable under Section 2.07(d), payable on demand and (ii) if the Acceleration Date shall not have occurred, at the Deposit Rate then in effect, payable within two Business Days of receipt by the Borrower of request therefor.

(d) Obligations Unconditional. The obligations of the Borrower under this Agreement in respect of each Letter of Credit shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, notwithstanding the following circumstances:

(i) any lack of validity or enforceability of any Letter of Credit Documents, any Loan Document, or any term or provision therein;

(ii) any amendment or waiver of or any consent to departure from all or any of the provisions of any Letter of Credit Document or any Loan Document;

(iii) the existence of any claim, set-off, defense or other right which the Borrower, any other party guaranteeing, or otherwise obligated with, the Borrower, any subsidiary or other Affiliate thereof or any other Person may have at any time against any beneficiary or transferee of such Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), the Issuing Bank, any Participant or any other Person, whether in connection with this Agreement, any other Loan Document, the transactions contemplated in this Agreement or in any Letter of Credit Documents or any unrelated transaction;

(iv) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

(v) payment by the Issuing Bank under such Letter of Credit against presentation of a draft or certificate which does not strictly comply with the terms of such Letter of Credit; or

(vi) any other act or omission to act or delay of any kind of the Issuing Bank, the Administrative Agent the Participants or any other Person or any other event, circumstance or happening whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of the Borrower’s obligations hereunder.

Without limiting the generality of the foregoing, it is expressly understood and agreed that the absolute and unconditional obligation of the Borrower hereunder to reimburse each payment or disbursement made by an Issuing Bank pursuant to a Letter of Credit will not be excused by the gross negligence of the Issuing Bank.

(e) Liability of Issuing Bank. The Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its use of such Letter of Credit. Neither the Issuing Bank nor any of its officers or directors shall be liable or responsible for:

(i) the use which may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith;

(ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged;

(iii) payment by the Issuing Bank against presentation of documents which do not comply with the terms of a Letter of Credit; or

(iv) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit (including the Issuing Bank’s own negligence),

except that the Borrower shall have a claim against the Issuing Bank, and the Issuing Bank shall be liable to, and shall promptly pay to, the Borrower, to the extent of any direct, as opposed to consequential (claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law), damages suffered by the Borrower which the Borrower prove were caused by (A) the Issuing Bank’s willful misconduct or gross negligence in determining whether documents presented under a Letter of Credit strictly comply with the terms of such Letter of Credit, (B) in the event the Issuing Bank did not follow its own standard operating procedures in all material respects or (C) the Issuing Bank has honored a Letter of Credit in violation of, to its knowledge, applicable law or court order. It is understood that the Issuing Bank may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary and, in making any payment under any Letter of Credit (A) the Issuing Bank’s exclusive reliance on the documents presented to it under such Letter of Credit as to any and all matters set forth therein, including reliance on the amount of any draft presented under such Letter of Credit, whether or not the amount due to the beneficiary thereunder equals the amount of such draft and whether or not any document presented pursuant to such Letter of Credit proves to be insufficient in any respect, if such document on its face appears to be in order, and whether or not any other statement or any other document presented pursuant to such Letter of Credit proves to be forged or invalid or any statement therein proves to be inaccurate or untrue in any respect whatsoever and (B) any noncompliance in any immaterial respect of the documents presented under such Letter of Credit with the terms thereof shall, in each case, be deemed not to constitute willful misconduct or gross negligence of the Issuing Bank.

(c) If the Deposit Bank is not offering Dollar deposits (in the applicable amounts) in the London interbank market, or the Deposit Bank reasonably determines that adequate and fair means do not otherwise exist for ascertaining the Deposit Rate, then the Deposits (or such parts, as applicable) shall be invested so as to earn a return equal to the greater of the Federal Funds Effective Rate and a rate reasonably determined by the Deposit Bank in accordance with banking industry rules on interbank compensation and the Deposit Bank hereby agrees to pay such greater amount to each Participant on its Deposit.

(d) If any Advance is repaid by the Borrower, or if any LC Disbursement under a Letter of Credit that has been funded by the Participants from the Deposits as provided in Section 2.01(c) shall be reimbursed by the Borrower, on a day other than on the last day of a Deposit Period, the Administrative Agent shall, upon receipt thereof, pay over such amounts to the Deposit Bank which will invest such amounts in overnight or short-term cash equivalent investments until the end of the Deposit Period at the time in effect and the Borrower shall pay to the Deposit Bank, upon the Deposit Bank’s request therefor, the amount, if any, by which the interest which would have accrued on a like amount of Deposits through the end of the then-current Deposit Period shall exceed the interest earned through the investment of the amount so reimbursed for the period from the date of such reimbursement through the end of the applicable Deposit Period, as determined by the Deposit Bank (such determination shall, absent manifest error, be presumed correct and binding on all parties hereto).

Each Participant severally agrees, on the terms and conditions set forth in this Agreement, to make LC Advances to the Borrower as required by and in accordance with Section 2.01(c) during the period from the Closing Date to the Maturity Date (or, if earlier, the Acceleration Date) in an amount not to exceed such Participant’s Commitment.

(b) Revolving Advances.

(i) The Revolving Loan Lender agrees, on the terms and conditions set forth in this Agreement, to make Revolving Advances to the Borrower during the period from the Closing Date to the Maturity Date (or, if earlier, the Acceleration Date) in an amount not to exceed the Revolving Loan Sublimit. Each Revolving Advance shall be in an aggregate amount not less than $2,000,000 and in integral multiples of $1,000,000 in excess thereof. Within the Revolving Loan Sublimit, the Borrower may from time to time borrow, prepay pursuant to Section 2.08 and reborrow under this Section 2.03(b).

(ii) Each Revolving Advance shall be made pursuant to a Notice of Borrowing, given not later than (i) if such Advance is a Eurodollar Advance, 10:00 a.m. (New York time) on the third Business Day before the requested Borrowing Date and (ii) if such Advance is a Base Rate Advance, 10:00 a.m. (New York time) on the requested Borrowing Date, in each case to the Administrative Agent’s Applicable Lending Office. The Administrative Agent shall give to the Revolving Loan Lender and each Participant prompt notice on the day of receipt of a timely Notice of Borrowing. The Notice of Borrowing shall be in writing specifying (A) the Borrowing Date (which shall be a Business Day), (B) the requested Type of Revolving Advances, (C) the aggregate amount of such Borrowing, and (D) if such Borrowing is to be comprised of Eurodollar Advances, the requested Interest Period. After the Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Administrative Agent will promptly make such funds available to the Borrower not later than 2:00 p.m. (New York time) at such account as the Borrower shall specify in writing to the Administrative Agent.

(iii) Upon the date of any Revolving Advance, the Revolving Loan Lender shall be deemed to have sold to each other Participant and each other Participant shall have been deemed to have purchased from the Revolving Loan Lender a participation in the Obligations related to such Revolving Advance equal to such Participant’s Pro Rata Share at such date. Each Participant acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Revolving Advances is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of a Default or an Event of Default, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(iv) The Revolving Loan Lender at any time in its sole and absolute discretion may request that each Participant promptly reimburse the Revolving Loan Lender for such Participant’s Pro Rata Share of such Revolving Advance, and, in satisfaction of that obligation, hereby irrevocably authorizes the Administrative Agent to withdraw a portion of its Deposits (if any) in an amount equal to such Participant’s Pro Rata Share of such Revolving Advance and pay the same over to the Revolving Loan Lender. The Deposit Bank hereby agrees to effect the withdrawal referred to in the immediately preceding sentence and all other withdrawals and payments requested by the Revolving Loan Lender pursuant to, and in accordance with, the terms of this Agreement. Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to this paragraph, the Administrative Agent shall distribute such payment to the Revolving Loan Lender or, to the extent that Participants have made payments pursuant to this paragraph to reimburse the Revolving Loan Lender for Revolving Advances, then to such Participants and the Revolving Loan Lender as their interests may appear (it being understood and agreed that any such payment to be made pursuant to this Section 2.03(b) to a Participant shall be made to the Administrative Agent for the account of such Participant and paid over to the Deposit Bank for deposit in the Deposit Account). The Borrower shall pay interest on the unpaid amount of such Revolving Advance (i) if the Acceleration Date shall have occurred, at the rate payable under Section 2.07(d), payable on demand and (ii) if the Acceleration Date shall not have occurred, at the Deposit Rate then in effect, payable within two Business Days of receipt by the Borrower of request therefor.

(i) Request for Increase. Provided there exists no Default or Event of Default, upon notice to, and with the consent of, the Administrative Agent (which shall promptly notify the Participants), the Borrower may from time to time request an increase in the aggregate Commitments by an amount (for all such requests) not exceeding $50,000,000; provided that (A) any such request for an increase shall be in a minimum amount of $25,000,000, and (B) the Borrower may make a maximum of two such requests. At the time of sending such notice, the Borrower (in consultation with the Administrative Agent) shall specify the time period within which each Participant is requested to respond (which shall in no event be less than ten Business Days from the date of delivery of such notice to the Participants).

(ii) Participant Elections to Increase. Each Participant shall notify the Administrative Agent within such time period whether or not it agrees to increase its Commitment and, if so, whether by an amount equal to, greater than, or less than its Pro Rata Share of such requested increase. Any Participant not responding within such time period shall be deemed to have declined to increase its Commitment.

(iii) Notification by Administrative Agent; Additional Participants. The Administrative Agent shall notify the Borrower of the Participants’ responses to each request made hereunder. To achieve the full amount of a requested increase and subject to the approval of the Administrative Agent and the Issuing Bank (which approvals shall not be unreasonably withheld), the Borrower may also invite additional Eligible Assignees to become Participants pursuant to a joinder agreement in form and substance reasonably satisfactory to the Administrative Agent.

(iv) Effective Date and Allocations. If the aggregate Commitments are increased in accordance with this Section, the Administrative Agent and the Borrower shall determine the effective date (the “Increase Effective Date”) and the final allocation of such increase. The Administrative Agent shall promptly notify the Borrower and the Participants of the final allocation of such increase and the Increase Effective Date.

(v) Conditions to Effectiveness of Increase. As a condition precedent to such increase, the Borrower shall deliver to the Administrative Agent a certificate of the Borrower and each Guarantor dated as of the Increase Effective Date signed by a Responsible Officer of such Person (i) certifying and attaching the resolutions adopted by such Person approving or consenting to such increase, (ii) in the case of the Borrower, certifying that, before and after giving effect to such increase, (A) the representations and warranties contained in Article IV and the other Loan Documents are true and correct on and as of the Increase Effective Date, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they are true and correct as of such earlier date, and except that for purposes of this Section 2.03(c), the representations and warranties contained in Section 4.05 shall be deemed to refer to the most recent statements furnished pursuant to clauses (a) and (b), respectively, of Section 5.06, and (B) no Default exists. The Borrower shall prepay any Advances outstanding on the Increase Effective Date (and pay any additional amounts required pursuant to Section 2.09) to the extent necessary to keep the outstanding Advances ratable with any revised Pro Rata Shares arising from any nonratable increase in the Commitments under this Section.

(vi) Conflicting Provisions. This Section shall supersede any provisions in Sections 2.13 or 10.01 to the contrary.

(d) Interest Elections. Each LC Advance shall initially be deemed to be a single Borrowing of a Eurodollar LC Advance with an Interest Period ending on the last day of the Deposit Period then in effect. Thereafter, in order to elect to Convert or Continue Advances under this Section, the Borrower shall deliver an irrevocable Notice of Conversion or Continuation to the Administrative Agent at its Applicable Lending Office no later than (i) 10:00 a.m. (New York time) at least one Business Day in advance of such requested Conversion date in the case of a Conversion of a Eurodollar Advance to a Base Rate Advance or (ii) 10:00 a.m. (New York time) at least three Business Days in advance of such requested Conversion date in the case of a Conversion into or Continuation of a Eurodollar Advance to another Eurodollar Advance. Each such Notice of Conversion or Continuation shall be in writing or by telex, telecopier or telephone, confirmed promptly in writing specifying (A) the requested Conversion or Continuation date (which shall be a Business Day), (B) the amount, Class, and Type of the Advance to be Converted or Continued, (C) whether a Conversion or Continuation is requested, and if a Conversion, into what Type of Advance, and (D) in the case of a Conversion to, or a Continuation of, a Eurodollar Advance, the requested Interest Period. Promptly after receipt of a Notice of Conversion or Continuation under this paragraph, the Administrative Agent shall provide each Participant with a copy thereof and, in the case of a Conversion to or a

Continuation of a Eurodollar Advance, notify each Participant of the interest rate under Sections 2.07(a)(ii). Notwithstanding anything in this Agreement to the contrary, Conversions of Eurodollar Advances may only be made at the end of the applicable Interest Period for such Advances; provided, however, that Conversions of Base Rate Advances may be made at any time. The portion of Advances comprising part of the same Borrowing that are converted to Advances of another Type shall constitute a new Borrowing.

(e) Certain Limitations. Notwithstanding anything in paragraph (d) above:

(i) at no time shall there be more than four Interest Periods applicable to outstanding Eurodollar Advances;

(ii) if any Participant shall, at least one Business Day before the date of any requested Borrowing, notify the Administrative Agent that any Change in Law makes it unlawful for such Participant or any of its Applicable Lending Offices to perform its obligations under this Agreement to make Eurodollar Advances, or to fund or maintain Eurodollar Advances, the right of the Borrower to select Eurodollar Advances from such Participant for such Borrowing or for any subsequent Borrowing shall be suspended until such Participant shall notify the Administrative Agent that the circumstances causing such suspension no longer exist, and such Participant’s Advance for such Borrowing shall be a Base Rate Advance;

(iii) if the Administrative Agent is unable to determine the Eurodollar Rate for any requested Borrowing and the Administrative Agent gives telephonic or telecopy notice thereof to the Borrower as soon as practicable, the right of the Borrower to select Eurodollar Advances or for any subsequent Borrowing and the obligation of the Participants to make such Eurodollar Advances shall be suspended until the Administrative Agent shall notify the Borrower and the Participants that the circumstances causing such suspension no longer exist, and each Advance comprising such Borrowing shall be a Base Rate Advance;

(iv) if the Majority Participants shall, by 11:00 a.m. (New York time) at least one Business Day before the date of any requested Borrowing, notify the Administrative Agent that the Eurodollar Rate will not adequately reflect the cost to such Participants of making or funding their respective Eurodollar Advances and the Administrative Agent gives telephonic or telecopy notice thereof to the Borrower as soon as practicable, the right of the Borrower to select Eurodollar Advances for such Borrowing or for any subsequent Borrowing and the obligation of the Participants to make Eurodollar Advances shall be suspended until the Administrative Agent shall notify the Borrower and the Participants that the circumstances causing such suspension no longer exist, and each Advance comprising such Borrowing shall be a Base Rate Advance;

(v) if the Borrower shall fail to select the duration or Continuation of any Interest Period for any Eurodollar Advances in accordance with the provisions contained in the definition of “Interest Period” in Section 1.01 and paragraph (d) above or shall fail to deliver a Notice of Conversion or Continuation, the Administrative Agent will forthwith so notify the Borrower and the Participants and such Advances will be made available to the Borrower on the date of such Borrowing as Base Rate Advances or, if such Advance is an existing Eurodollar Advance, Convert into Base Rate Advances; and

(vi) no Advance may be Converted or Continued as a Eurodollar Advance at any time when a Default or an Event of Default has occurred and is continuing.

(f) Notices Irrevocable. Each Notice of Conversion or Continuation delivered by the Borrower shall be irrevocable and binding on the Borrower. In the case of any Borrowing which the related Notice of Conversion or Continuation specifies is to be comprised of Eurodollar Advances, the Borrower shall indemnify each Participant against any loss, out-of-pocket cost or expense actually incurred by such Participant as a result of any failure to fulfill on or before the date specified in such Notice of Conversion or Continuation for such Borrowing the applicable conditions set forth in Article III, including, without limitation, any loss, cost or expense actually incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Participant to fund the Advance to be made by such Participant as part of such Borrowing when such Advance, as a result of such failure, is not made on such date.

(g) Noteless Agreement; Evidence of Indebtedness.

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

(ii) The Administrative Agent shall also maintain accounts in which it will record (A) the amount of each Advance made hereunder, the Class and Type thereof and the Interest Period with respect thereto, (B) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Participant hereunder and (C) the amount of any sum received by the Administrative Agent hereunder from the Borrower and each Participant’s share thereof.

(iii) The entries maintained in the accounts maintained pursuant to paragraphs (i) and (ii) above shall be conclusive evidence of the existence and amounts of the Obligations therein recorded absent manifest error; provided, however, that the failure of the Administrative Agent or any Participant to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Obligations in accordance with their terms.

(iv) Any Participant may request that the Advances owing to such Participant be evidenced by a Note. In such event, the Borrower shall execute and deliver to such Participant a Note payable to the order of such Participant and its registered assigns. Thereafter, the Advances evidenced by such Note and interest thereon shall at all times (including after any assignment pursuant to Section 10.06) be represented by one or more Notes payable to the order of the payee named therein or any assignee pursuant to Section 10.06, except to the extent that any such Participant or assignee subsequently returns any such Note for cancellation and requests that such Advances once again be evidenced as described in paragraphs (i) and (ii) above.

Section 2.04 Fees.

(a) Agent’s Fees. The Borrower agrees to pay to the Administrative Agent and the Arranger the fees as separately agreed upon by the Borrower in the Fee Letter.

(b) Facility Fees. The Borrower agrees to pay to the Administrative Agent for the account of each Participant a facility fee (a “Facility Fee”) on the aggregate Commitments at a rate per annum equal to 5.00%. The Facility Fees payable pursuant to this clause (b) are due quarterly in arrears on or before the later of (i) the last Business Day of each March, June, September and December and (ii) five Business Days after receipt by the Borrower of an invoice therefor, commencing with the first such date to occur after the Closing Date, and on the Maturity Date. In the event that the Borrower obtains a rating from S&P and Moody’s greater than B and B2, respectively, then the Facility Fee rate per annum shall be automatically reduced to 2.75%.

(d) Letter of Credit Fees.

(i) The Borrower agrees to pay to the Issuing Bank a fronting fee equal to 0.125% per annum of the aggregate Commitments. In addition, the Borrower agrees to pay to the Issuing Bank a fronting fee for each Documentary Letter of Credit or Financial Letter of Credit equal to a percentage rate per annum to be agreed upon of the initial stated amount of such Letter of Credit (or, with respect to any subsequent increase to the stated amount of any such Letter of Credit, such increase in the stated amount). Such fee shall be based on the maximum amount available to be drawn from time to time under such Letter of Credit from the date of issuance of the Letter of Credit until its expiration date. Each such fee shall be payable quarterly in arrears on or before the later of (A) the last Business Day of each March, June, September and December and (B) five Business Days after receipt by the Borrower of an invoice therefor, commencing with the first such date to occur after the Closing Date, until the earlier of its expiration date or the Maturity Date. All such fees shall be computed on the basis of the actual number of days elapsed in a year of 360 days.

(ii) In addition, the Borrower agrees to pay to the Issuing Bank all customary transaction costs and fees charged by the Issuing Bank in connection with the issuance, amendment, renewal, extension, advising, confirmation or transfer of a Letter of Credit for the Borrower’s account, such costs and fees to be due and payable on the date specified by the Issuing Bank in the invoice for such costs and fees.

(e) Commitment Reduction Premium. If any Commitment reduction or termination pursuant to Section 2.05 occurs on or before the first anniversary of the Closing Date, then on the date of such Commitment reduction or termination the Borrower shall pay to the Administrative Agent for the account of the Participants a prepayment premium equal to 2.0% of the amount of such Commitment reduction or termination.

(f) Generally. All such fees shall be paid on the dates due, in immediately available Dollars to the Administrative Agent for distribution, if and as appropriate, among the Participants, except that the fees payable pursuant to Section 2.04(d)(i) and (ii) shall be paid directly to the Issuing Bank. Once paid, absent manifest error, none of these fees shall be refundable under any circumstances.

Section 2.05 Reduction of the Commitments.

(a) The Borrower shall have the right, upon at least five Business Days’ irrevocable notice to the Administrative Agent, to terminate in whole or reduce ratably in part the unused portion of the Commitments; provided that each partial reduction of Commitments shall be in the minimum aggregate amount of $5,000,000 and in integral multiples of $1,000,000 in excess thereof (or such lesser amount as may then be outstanding); and provided further that, except as otherwise provided in (b) and (c) below, the aggregate amount of the Commitments may not be reduced below the sum of the aggregate principal amount of the outstanding Advances and the Letter of Credit Exposure.

(b) The Commitments shall be reduced by the amount of each mandatory prepayment required to be made pursuant to Section 2.08(c)(iii) or (iv).

(c) To the extent that a Commitment reduction made in accordance with Section 2.05(a) or (b) would result in the Letter of Credit Exposure of any Participant exceeding such Participant’s Commitment, the Borrower shall reduce the Letter of Credit Exposure such that after giving effect to such reduction such excess has been eliminated. Such reductions shall be made to the extent necessary by first prepaying such Participant’s Advances outstanding at such time, and second depositing in the LC Cash Collateral Account an amount of cash equal to 105% of the remaining excess to be held by the Collateral Agent as collateral and applied to satisfy drawings under Letters of Credit as they occur. At the time of any reduction or termination of the Commitments of any Participant pursuant to this Section 2.05 or on the Maturity Date, the Administrative Agent shall request the Deposit Bank to withdraw from the Deposit Account and to pay the same over to it, and shall return to such Participant, the Participant’s Deposits in an aggregate amount equal to such reduction (or the amount of the Commitment being terminated) and the Deposit Bank agrees that it shall make such withdrawal. Any reduction or termination of the Commitments pursuant to this Section 2.05 shall be permanent, with no obligation of the Revolving Participants to reinstate such Commitments and the facility fees provided for in Section 2.04(b) shall thereafter be computed on the basis of the Commitments as so reduced. The Administrative Agent shall give each Participant prompt notice of any commitment reduction or termination.

Section 2.06 Repayment. The Borrower shall repay the outstanding principal amount of the Advances and any outstanding Reimbursement Obligations on the Maturity Date.

Section 2.07 Interest. The Borrower shall pay interest on the unpaid principal amount of each Advance made by each Participant to it from the date of such Advance until such principal amount shall be paid in full, at the following rates per annum:

(a) Advances.

(i) Base Rate Advances. If such Advance is a Base Rate Advance, a rate per annum equal to the Adjusted Base Rate minus 1.00%, payable in arrears on the last Business Day of each calendar quarter and on the date such Base Rate Advance shall be paid in full.

(ii) Eurodollar Advances. If such Advance is a Eurodollar Advance, a rate per annum equal to the Eurodollar Rate for such Interest Period, payable in arrears on the last day of such Interest Period, and, in the case of Interest Periods of greater than three months, on each Business Day which occurs at three month intervals from the first day of such Interest Period; provided that the Eurodollar Rate for Advances for the period commencing on the date on which such Advance was first deemed to have been made through the end of the then current Deposit Period shall equal the Deposit Rate for such period.

(b) Additional Interest on Eurodollar Advances. The Borrower shall pay to each Participant, so long as any such Participant shall be required under regulations of the Federal Reserve Board to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, additional interest on the unpaid principal amount of the Eurodollar Advances of such Participant, from the effective date of such Advance until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the Eurodollar Rate for the Interest Period for such Advance from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Participant for such Eurodollar Advances for such Interest Period, payable on each date on which interest is payable on such Advance. Such additional interest payable to any Participant shall be determined by such Participant and notified to the Borrower through the Administrative Agent (such notice to include the calculation of such additional interest, which calculation shall be conclusive absent manifest error, and be accompanied by any evidence indicating the need for such additional interest as the Borrower may reasonably request).

(c) Usury Recapture. In the event the rate of interest chargeable under this Agreement at any time (calculated after giving affect to all items charged which constitute “interest” under applicable laws, including fees and margin amounts, if applicable) is greater than the Maximum Rate, the unpaid principal amount of the Advances shall bear interest at the Maximum Rate until the total amount of interest paid or accrued on the Advances equals the amount of interest which would have been paid or accrued on the Advances if the stated rates of interest set forth in this Agreement had at all times been in effect.

In the event, upon payment in full of the Advances, the total amount of interest paid or accrued under the terms of this Agreement and the Advances is less than the total amount of interest which would have been paid or accrued if the rates of interest set forth in this Agreement had, at all times, been in effect, then the Borrower shall, to the extent permitted by applicable law, pay the Administrative Agent for the account of the Participants an amount equal to the difference between (i) the lesser of (A) the amount of interest which would have been charged on its Advances if the Maximum Rate had, at all times, been in effect and (B) the amount of interest which would have accrued on its Advances if the rates of interest set forth in this Agreement had at all times been in effect and (ii) the amount of interest actually paid under this Agreement on its Advances.

In the event the Participants ever receive, collect or apply as interest any sum in excess of the Maximum Rate, such excess amount shall, to the extent permitted by law, be applied to the reduction of the principal balance of the Advances, and if no such principal is then outstanding, such excess or part thereof remaining shall be paid to the Borrower.

In determining whether the interest contracted for, charged, or received by a Participant 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.

(d) Default Interest. Upon the occurrence and during the continuance of an Event of Default, the Borrower shall on demand from time to time pay interest, to the extent permitted by law, on any outstanding amounts to but excluding the date of actual payment (after as well as before judgment) (a) with respect to any amount of principal of any Advance, at the rate otherwise applicable to such Advance pursuant to this Section 2.07 plus 2.00% per annum and (b) in all other cases, at a rate per annum (computed on the basis of the actual number of days elapsed over a year of 365 or 366 days, as the case may be, when determined by reference to the Prime Rate and over a year of 360 days at all other times) equal to the rate that would be applicable to a Base Rate Advance plus 2.00%.

Section 2.08 Prepayments.

(a) Right to Prepay. The Borrower shall have no right to prepay any principal amount of any Advance except as provided in this Section 2.08.

(b) Optional. The Borrower may elect to prepay, in whole or in part, any of the Advances owing by it to the Participants, after giving prior written notice of such election by (i) 10:00 a.m. (New York time) at least three Business Days before such prepayment date in the case of Borrowings which are comprised of Eurodollar Advances, and (ii) 10:00 a.m. (New York time) on or before the Business Day of such prepayment, in case of Borrowings which are comprised of Base Rate Advances, in each case to the Administrative Agent stating the proposed date and aggregate principal amount of such prepayment. If any such notice is given, the Administrative Agent shall give prompt notice thereof to each Participant and the Borrower shall prepay LC Advances comprising part of the same Borrowing in whole or ratably in part in an aggregate principal amount equal to the amount specified in such notice, together with accrued and unpaid interest to the date of such prepayment on the principal amount prepaid and amounts, if any, required to be paid pursuant to Section 2.09 as a result of such prepayment being made on such date; provided, however, that each partial prepayment shall be in an aggregate principal amount not less than $5,000,000 and in integral multiples of $1,000,000 in excess thereof (or such lesser amount as may then be outstanding).

(i) Deficiency. On any date on which the sum of the Advances and the Letter of Credit Exposure with respect to Documentary Letters of Credit and Financial Letters of Credit is greater than the Revolving Loan Sublimit, the Borrower agrees to make a mandatory prepayment of the Advances, together with accrued and unpaid interest to the date of such prepayment on the principal amount prepaid and amounts, if any, required to be paid pursuant to Section 2.09 as a result of such prepayment being made on such date, in the amount of such deficiency, or if the Advances have been repaid in full, make deposits into the LC Cash Collateral Account in the remaining amount of such deficiency to provide cash collateral for the Letter of Credit Exposure with respect to such Documentary Letters of Credit and Financial Letters of Credit to the extent of such excess.

(ii) Reduction of Commitments. On the date of each reduction of the aggregate Commitments pursuant to Section 2.05, the Borrower agrees to make a prepayment in respect of the outstanding amount of the Advances, or if the Advances have been repaid in full, make deposits into the LC Cash Collateral Account to provide cash collateral for the Letter of Credit Exposure to the extent, if any, that the aggregate unpaid principal amount of all LC Advances plus the Letter of Credit Exposure exceeds the Commitments, as so reduced.

(iii) Asset Dispositions. If any Loan Party or any of its Subsidiaries shall at any time or from time to time:

(A) make or agree to make an Asset Disposition (other than an Asset Disposition directly resulting from the discontinuance of the Nigerian Operations); or

(B) suffer an Event of Loss;

then (A) the Borrower shall promptly notify the Administrative Agent of such proposed Asset Disposition or Event of Loss (including the amount of the estimated Net Proceeds to be received by any Loan Party and/or any of its Subsidiaries in respect thereof) and (B) promptly upon receipt by such Loan Party and/or any of its Subsidiaries of the Net Proceeds of such Asset Disposition or Event of Loss (unless such Loan Party has delivered a Notice of Reinvestment to the Administrative Agent and made a Qualified Investment on or before the Reinvestment Prepayment Date), the Borrower shall deliver, or cause to be delivered, such Net Proceeds to the Administrative Agent for distribution to the Participants as a prepayment of the Advances, with a corresponding reduction of the Commitments, together with accrued and unpaid interest to the date of such prepayment on the principal amount prepaid and amounts, if any, required to be paid pursuant to Section 2.09 as a result of such prepayment being made on such date, or if the Advances have been repaid in full, make deposits into the LC Cash Collateral Account in the remaining amount of such excess to provide cash collateral for the Aggregate Letter of Credit Exposure; provided, however, that notwithstanding the foregoing, in the case of any Net Proceeds constituting the Reinvestment Deferred Amount with respect to a Reinvestment Event, the Borrower shall repay the Advances in an amount equal to the Reinvestment Prepayment Amount applicable to such Reinvestment Event, if any, on the Reinvestment Prepayment Date with respect to such Reinvestment Event if the applicable Loan Party fails to make a Qualified Investment.

(iv) Debt Issuance. Promptly upon the receipt by any Loan Party or any of their respective Subsidiaries of the Net Debt Proceeds, the Borrower shall deliver, or cause to be delivered, to the Administrative Agent an amount equal to 100% of such Net Debt Proceeds for application to the Advances, with a corresponding reduction of the Commitments, together with accrued interest to the date of such prepayment on the principal amount prepaid and amounts, if any, required to be paid pursuant to Section 2.09 as a result of such prepayment being made on such date, or if the LC Advances have been repaid in full, make deposits into the LC Cash Collateral Account in the remaining amount of such excess to provide cash collateral for the Letter of Credit Exposure.

(v) Clean Down Period. At least once before each anniversary of the Closing Date, during the term of this Agreement, the Borrower agrees to make a prepayment in respect of the outstanding amount of the Revolving Advances so that there shall be a period of ten (10) consecutive Business Days during which there are no Advances outstanding and no Advances will be made.

(vi) Application of Prepayments. Each prepayment pursuant to this Section 2.08(c) shall be accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.09 as a result of such prepayment being made on such date. Notwithstanding the foregoing, any Participant may elect, by notice to the Administrative Agent by telephone (confirmed by telecopy) at least one Business Day prior to the prepayment date, to decline all or any portion of any prepayment of its Advances pursuant to Section 2.08 above, in which case the aggregate amount of the prepayment that would have been applied to prepay such Advances but was so declined shall be returned to the Borrower.

(d) Illegality. If any Participant shall notify the Administrative Agent and the Borrower that any Change in Law makes it unlawful for such Participant or its Applicable Lending Office to perform its obligations under this Agreement or to make or maintain Eurodollar Advances then outstanding hereunder, the Borrower shall, no later than 10:00 a.m. (New York time) (i) (A) if not prohibited by any Legal Requirement to maintain such Eurodollar Advances for the duration of the Interest Period, on the last day of the Interest Period for each outstanding Eurodollar Advance or (B) if prohibited by any Legal Requirement to maintain such Eurodollar Advances for the duration of the Interest Period, on the second Business Day following its receipt of such notice, prepay all Eurodollar Advances of all of the Participants then outstanding, together with accrued and unpaid interest on the principal amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.09 as a result of such prepayment being made on such date, (ii) each Participant shall simultaneously make a Base Rate Advance or, if not otherwise prohibited, make an Eurodollar Advance in an amount equal to the aggregate principal amount of the affected Eurodollar Advances, and (iii) the right of the Borrower to select Eurodollar Advances shall be suspended until such Participant shall notify Administrative Agent that the circumstances causing such suspension no longer exist. Each Participant agrees to use commercially reasonable efforts (consistent with its internal policies and subject to legal and regulatory restrictions) to designate a different Applicable

Lending Office if the making of such designation would avoid the effect of this paragraph and would not, in the reasonable judgment of such Participant, be otherwise disadvantageous to such Participant.

(e) Ratable Payments; Effect of Notice. Each payment of any Advance pursuant to this Section 2.08 or any other provision of this Agreement shall be made in a manner such that all LC Advances comprising part of the same Borrowing are paid in whole or ratably in part. All notices given pursuant to this Section 2.08 shall be irrevocable and binding upon the Borrower.

Section 2.09 Funding Losses. If (a) any payment of principal of any Eurodollar Advance is made other than on the last day of the Interest Period for such Advance as a result of any payment pursuant to Section 2.08 or the acceleration of the maturity of the Advances pursuant to Article VII or (b) if the Borrower fails to make a principal or interest payment with respect to any Eurodollar Advance on the date such payment is due and payable, the Borrower shall, within three Business Days of any written demand sent by any Participant to the Borrower through the Administrative Agent, pay to Administrative Agent for the account of such Participant any amounts (without duplication of any other amounts payable in respect of breakage costs) required to compensate such Participant for any additional losses, out-of-pocket costs or expenses which it may reasonably incur as a result of such payment or nonpayment, including, without limitation, any loss, cost or expense actually incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Participant to fund or maintain such Advance. A certificate of any Participant setting forth any amount or amounts that such Participant is entitled to receive pursuant to this Section shall be delivered to the Borrower and shall be conclusive absent manifest error.

Section 2.10 Increased Costs.

(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 Participant (except any reserve requirement reflected in the Eurodollar Rate Reserve Percentage), or the Issuing Bank;

(ii) subject any Participant or the Issuing Bank 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 Advance made by it, or change the basis of taxation of payments to such Participant or the Issuing Bank in respect thereof (except for Indemnified Taxes or Other Taxes covered by Section 2.12 and the imposition of, or any change in the rate of, any Excluded Tax payable by such Participant or the Issuing Bank); or

(iii) impose on any Participant, the Issuing Bank, or the London interbank market any other condition, cost or expense affecting this Agreement or Eurodollar Advances made by such Participant, the Issuing Bank, or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Participant of making or maintaining any Eurodollar Advance (or of maintaining its obligation to make any such Advance), or to increase the cost to such Participant or the Issuing Bank 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 Participant or the Issuing Bank (whether of principal, interest or any other amount) then, upon request of such Participant or the Issuing Bank, the Borrower will pay to such Participant or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Participant or the Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered.

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

(c) Certificates for Reimbursement. A certificate of a Participant or the Issuing Bank setting forth the amount or amounts necessary to compensate such Participant or the Issuing Bank or any of their respective holding companies, as the case may be, as specified in paragraph (a) or (b) of this Section and delivered to the Borrower shall be conclusive absent manifest error. The Borrower shall pay such Participant or the Issuing Bank, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Delay in Requests. Failure or delay on the part of any Participant or the Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Participant’s or the Issuing Bank’s right to demand such compensation, provided that the Borrower shall not be required to compensate a Participant or the Issuing Bank pursuant to this Section for any increased costs incurred or reductions suffered more than nine months prior to the date that such Participant or the Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Participant’s or the Issuing Bank’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 nine-month period referred to above shall be extended to include the period of retroactive effect thereof).

Section 2.11 Payments and Computations.

(a) Payment Procedures. The Borrower shall make each payment under this Agreement not later than 12:00 noon (New York time) on the day when due to the Administrative Agent at the Administrative Agent’s Applicable Lending Office in immediately available funds. Each Advance shall be repaid and each payment of interest thereon shall be paid in Dollars. All payments shall be made without setoff, deduction, or counterclaim. The Administrative Agent will promptly thereafter, and in any event prior to the close of business on the day any timely payment is made, cause to be distributed like funds relating to the payment of principal, interest or fees ratably to the Participants (other than amounts payable solely to the Administrative Agent, or a specific Participant pursuant to Section 2.04(b), 2.09, 2.10 or 2.12, but after taking into account payments effected pursuant to Section 10.04) in accordance with each Participant’s Pro Rata Share to the Participants for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Participant to such Participant for the account of its Applicable Lending Offices, in each case to be applied in accordance with the terms of this Agreement or, in the case of Advances funded by Participants from Deposits, the Administrative Agent shall deposit same in the Deposit Account in accordance with Section 2.02(d).

(b) Computations. All computations of interest based on the Prime Rate shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Federal Funds Effective Rate or the Eurodollar Rate and of fees shall be made by the Administrative Agent, on the basis of a year of 360 days, in each case for the actual number of days (including the first day, but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Administrative Agent of an interest rate shall be conclusive and binding for all purposes, absent manifest error.

(c) Non-Business Day Payments. Whenever any payment shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be.

(d) Agent Reliance. Unless the Administrative Agent shall have received written notice from the Borrower prior to the date on which any payment is due to the Participants that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Participant on such date an amount equal to the amount then due to such Participant. If and to the extent the Borrower shall not have so made such payment in full to Administrative Agent, each Participant shall repay to the Administrative Agent forthwith on demand such amount distributed to such Participant, together with interest thereon, for each day from the date such amount is distributed to such Participant until the date such Participant repays such amount to the Administrative Agent, at the greater of the Federal Funds Effective Rate for such day and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

Section 2.12 Taxes.

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

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

(c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent, each Participant and the Issuing Bank, within 10 days after demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by the Administrative Agent, such Participant or the Issuing Bank, 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 as to the amount of such payment or liability delivered to the Borrower by a Participant or the Issuing Bank (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Participant or the Issuing Bank, 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 Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Status of Participants. Any Foreign Participant that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the 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 the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by the 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 Participant or the Issuing Bank if requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Participant or the Issuing Bank is subject to backup withholding or information reporting requirements.

Without limiting the generality of the foregoing, in the event that the Borrower is resident for tax purposes in the United States of America, any Foreign Participant shall deliver to the 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 Participant becomes a Participant under this Agreement (and from time to time thereafter upon the request of the Borrower or the Administrative Agent, but only if such Foreign Participant is legally entitled to do so), whichever of the following is applicable:

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

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

(iii) in the case of a Foreign Participant claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code, (x) a certificate to the effect that such Foreign Participant is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of the Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code and (y) two duly completed copies 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 the Borrower to determine the withholding or deduction required to be made.

(f) Treatment of Certain Refunds. If the Administrative Agent, a Participant or the Issuing Bank determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower have paid additional amounts pursuant to this Section, it shall pay to the Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 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 Participant or the Issuing Bank, 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 the Borrower, upon the request of the Administrative Agent, such Participant or the Issuing Bank, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent, such Participant or the Issuing Bank in the event the Administrative Agent, such Participant or the Issuing Bank is required to repay such refund to such Governmental Authority. This paragraph shall not be construed to require the Administrative Agent, any Participant or the Issuing Bank to make available its tax returns (or any other information relating to its taxes that it deems confidential) to the Borrower or any other Person.

Section 2.13 Sharing of Payments, Etc. If any Participant shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest

on any of its Advances or other obligations hereunder resulting in such Participant’s receiving payment of a proportion of the aggregate amount of its Advances and accrued interest thereon or other such obligations greater than its Pro Rata Share, then the Participant receiving such greater proportion shall (a) notify the Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the Advances and such other obligations of the other Participants, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Participants ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Advances and other amounts owing them, provided that: (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and (ii) the provisions of this paragraph shall not be construed to apply to (x) any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or (y) any payment obtained by a Participant as consideration for the assignment of or sale of a participation in any of its Advances or participations in Letters of Credit to any assignee or participant, other than to the Borrower or any Subsidiary thereof (as to which the provisions of this paragraph shall apply). Each Loan Party consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Participant acquiring a participation pursuant to the foregoing arrangements may exercise against each Loan Party rights of setoff and counterclaim with respect to such participation as fully as if such Participant were a direct creditor of each Loan Party in the amount of such participation.

Section 2.14 Applicable Lending Offices. Each Participant may book its Advances at any Applicable Lending Office selected by such Participant and may change its Applicable Lending Office from time to time. All terms of this Agreement shall apply to any such Applicable Lending Office and the Advances shall be deemed held by each Participant for the benefit of such Applicable Lending Office. Each Participant may, by written notice to the Administrative Agent and the Borrower designate replacement or additional Applicable Lending Offices through which Advances will be made by it and for whose account repayments are to be made.

Section 2.15 Replacement of Participants. If a Participant (a “Non-Consenting Participant”) refuses to consent to an amendment, modification or waiver of this Agreement that, pursuant to Section 10.01, requires consent of each Participant affected thereby (any such Participant, a “Subject Participant”), so long as (a) no Event of Default shall have occurred and be continuing and the Borrower has obtained a commitment from another Participant or an Eligible Assignee to purchase at par the Subject Participant’s Advances and assume the Subject Participant’s Commitments and all other obligations of the Subject Participant hereunder and (b) such Participant is not an Issuing Bank with respect to any Letters of Credit outstanding (unless all such Letters of Credit are terminated or arrangements acceptable to such Issuing Bank (such as a “back-to-back” letter of credit) are made), the Borrower may require the Subject Participant to assign all of its Advances and Commitments to such other Participant, Participants, Eligible Assignee or Eligible Assignees pursuant to the provisions of Section 10.06; provided that, prior to or concurrently with such replacement, (i) the Subject Participant shall have received payment in full of all principal, interest, fees and other amounts (including all amounts under Sections 2.10 and/or 2.12 (if applicable)) through such date of replacement, plus the amount of, and interest accrued with respect to, any Deposit of such Participant and a release from its obligations under the Loan Documents, (ii) all of the requirements for such assignment contained in Section

10.06, including, without limitation, the consent of Administrative Agent (if required) and the receipt by Administrative Agent of an executed Assignment and Acceptance executed by the assignee (Administrative Agent being hereby authorized to execute any Assignment and Acceptance on behalf of a Subject Participant relating to the assignment of Advances and Commitments of such Subject Participant) and other supporting documents, have been fulfilled, (iii) in the event such Subject Participant is a Non-Consenting Participant, each assignee shall consent, at the time of such assignment, to each matter in respect of which such Subject Participant was a Non-Consenting Participant and (iv) no more than 25% of the aggregate Commitments can be assigned to such other Participants or Eligible Assignees pursuant to this Section 2.15 at any one time.

Section 7.07 Letters of Credit.

(a) If any Event of Default shall occur and be continuing, on the Business Day on which the Borrower receives notice from the Collateral Agent demanding the deposit of cash collateral pursuant to this paragraph, the Borrower agrees to deposit into the LC Cash Collateral Account, an amount in Dollars in cash equal to 105% of the Letter of Credit Exposure for all Participants; provided that the obligation to deposit such amount will become effective immediately, and such deposit will become immediately due and payable, without demand or other notice of any kind, upon the occurrence of the Acceleration Date. Each such deposit pursuant to this paragraph shall be held by the Collateral Agent as collateral for the payment and performance of the obligations of the Borrower with respect to Letters of Credit under Section 2.01. The Collateral Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Moneys in such account shall be applied by the Collateral Agent to reimburse the Issuing Bank for LC Disbursements made by it with respect to Letters of Credit for which the Issuing Bank has not been reimbursed pursuant to Section 2.01 and, to the extent not so applied, shall be held to satisfy drawings under Letters of Credit as they occur. If the Borrower is required to deposit an amount in the LC Cash Collateral Account as a result of the occurrence of an Event of Default (and the Acceleration Date shall not have occurred), such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default have been cured or waived. If at any time either (x) the amount of cash held in the LC Cash Collateral Account exceeds 105% of the Letter of Credit Exposure for all Participants or (y) any cash remains on deposit in the LC Cash Collateral Account after all Letters of Credit have either been fully drawn or expired, then such excess or remaining amount shall be (A) if the Acceleration Date shall have occurred or Event of Default shall be continuing, applied to the other Obligations, if any, in the order set forth in Section 7.06 above and (B) otherwise, returned to the Borrower.

(b) On the Acceleration Date, the Administrative Agent shall request the Deposit Bank to withdraw from the Deposit Account and to pay same over to it, and shall return to each Participant such Participant’s Deposits in an amount equal to the amount by which such Participant’s Commitments at such time exceeds such Participant’s Letter of Credit Exposure at

such time. If on such date the Issuing Bank has made LC Disbursements in respect of Letters of Credit for which the Issuing Bank has not been reimbursed pursuant to Section 2.01(c) or by application of amounts held in the LC Cash Collateral Account pursuant to Section 7.07(a), the Administrative Agent shall request the Deposit Bank to withdraw a portion of each Participant’s Deposits (if any) in an amount equal to such Participant’s Pro Rata Share of such unreimbursed LC Disbursements and deliver such amount to the Issuing Bank in satisfaction of the obligations of the respective Participants under Section 2.01(c) (but not the Borrower’s Reimbursement Obligation under Section 2.01(c), which obligation shall only be satisfied by payment by the Borrower to the Administrative Agent for application in accordance with Section 2.01(c) or by application of amounts held in the LC Cash Collateral Account as set forth in Section 7.07(a) above). The Administrative Agent shall then request the Deposit Bank to withdraw all amounts remaining in the Deposit Account and deposit same in a new separate account or accounts for each applicable Participant maintained with the Collateral Agent (each a “LC Reserve Account”). The Administrative Agent shall deposit in each Participant’s LC Reserve Account such Participant’s Pro Rata Share of the amounts received from the Deposit Account as provided above. The Collateral Agent shall have sole dominion and control over each LC Reserve Account, and the amounts deposited in each LC Reserve Account shall be held in such LC Reserve Account until withdrawn as provided in paragraph (c), (d), or (e) below. The Collateral Agent shall maintain records enabling it to determine the amounts paid over to it and deposited in the LC Reserve Accounts in respect of each Letter of Credit and the amounts on deposit in respect of each Letter of Credit attributable to each Participant’s Pro Rata Share. The amounts held in each Participant’s LC Reserve Account shall be held as a reserve against the LC Exposures, shall be the property of such Participant, shall not constitute a loan to or give rise to any claim of or against any Loan Party and shall not give rise to any obligation on the part of any Loan Party to pay interest to such Participant, it being agreed that the reimbursement obligations in respect of Letters of Credit shall arise only at such times as drawings are made thereunder, as provided in Section 2.01.

(c) In the event that after the Acceleration Date any drawing shall be made in respect of a Letter of Credit which is not immediately reimbursed by the Borrower (including by application of amounts held in the LC Cash Collateral Account pursuant to Section 7.07(a)), the Collateral Agent shall, at the request of the Issuing Bank, withdraw from the LC Reserve Account of each Participant any amounts, up to the amount of such Participant’s Pro Rata Share of such drawing deposited in respect of such Letter of Credit and remaining on deposit and deliver such amounts to the Issuing Bank in satisfaction of the obligation of the respective Participants under Section 2.01(c) (but not the Borrower’s Reimbursement Obligation under Section 2.01(c), which obligation shall only be satisfied by payment by the Borrower to the Administrative Agent for application in accordance with Section 2.01(c) or by application of amounts held as cash collateral as set forth in Section 7.07(a) above).

(d) In the event that after the Acceleration Date any Letter of Credit shall expire undrawn, the Collateral Agent shall withdraw from the LC Reserve Account of each Participant the amount remaining on deposit therein in respect of such Letter of Credit and distribute such amount to such Participant.

(e) With the prior written approval of the Collateral Agent and the Issuing Bank, any Participant may withdraw the amount held in its LC Reserve Account. Any Participant making

such a withdrawal shall be unconditionally obligated, in the event there shall subsequently be a drawing under any Letter of Credit, to pay over to the Collateral Agent, for the account of the Issuing Bank on demand, its Pro Rata Share of such drawing or payment.

(f) Pending the withdrawal by any Participant of any amounts from its LC Reserve Accounts as contemplated by the above paragraphs, the Collateral Agent will, at the direction of such Participant and subject to such rules as the Collateral Agent may prescribe for the avoidance of inconvenience, invest such amounts. Each Participant that has not withdrawn all of the amounts in its LC Reserve Accounts as provided in paragraph (e) above shall have the right, at intervals reasonably specified by the Collateral Agent, to withdraw the earnings on investments so made by the Collateral Agent with amounts remaining in its LC Reserve Accounts and to retain such earnings for its own account.

ARTICLE VIII

THE GUARANTY

Section 8.01 Liabilities Guaranteed. Each Guarantor hereby, joint and severally, irrevocably and unconditionally guarantees the prompt payment at maturity of the Obligations.

Section 8.02 Nature of Guaranty. This guaranty is an absolute, irrevocable, completed and continuing guaranty of payment and not a guaranty of collection, and no notice of the Obligations or any extension of credit already or hereafter contracted by or extended to the Borrower need be given to any Guarantor. This guaranty may not be revoked by any Guarantor and shall continue to be effective with respect to the Obligations arising or created after any attempted revocation by such Guarantor and shall remain in full force and effect until the Obligations are paid in full and the Commitments are terminated, notwithstanding that from time to time prior thereto no Obligations may be outstanding. The Borrower and the Participants may modify, alter, rearrange, extend for any period and/or renew from time to time, the Obligations, and the Participants may waive any Default or Events of Default without notice to any Guarantor and in such event each Guarantor will remain fully bound hereunder on the Obligations. This guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of the Obligations is rescinded or must otherwise be returned by any of the Participants upon the insolvency, bankruptcy or reorganization of the Borrower or otherwise, all as though such payment had not been made. This guaranty may be enforced by the Administrative Agent, the Participants and any subsequent holder of any of the Obligations and shall not be discharged by the assignment or negotiation of all or part of the Obligations. Each Guarantor hereby expressly waives presentment, demand, notice of non-payment, protest and notice of protest and dishonor, notice of Default or Event of Default, and also notice of acceptance of this guaranty, acceptance on the part of the Participants being conclusively presumed by the Participants’ request for this guaranty and the Guarantors’ being party to this Agreement.

Section 8.03 Agent’s Rights. Each Guarantor authorizes the Administrative Agent, without notice or demand and without affecting any Guarantor’s liability hereunder, to take and hold security for the payment of its obligations under this Article VIII and/or the Obligations, and exchange, enforce, waive and release any such security; and to apply such security and direct the order or manner of sale thereof as the Administrative Agent in its discretion may determine,

and to obtain a guaranty of the Obligations from any one or more Persons and at any time or times to enforce, waive, rearrange, modify, limit or release any of such other Persons from their obligations under such guaranties.

Section 8.04 Guarantor’s Waivers.

(a) General. Each Guarantor waives any right to require any of the Participants to (i) proceed against the Borrower or any other person liable on the Obligations, (ii) enforce any of their rights against any other guarantor of the Obligations, (iii) proceed or enforce any of their rights against or exhaust any security given to secure the Obligations, (iv) have the Borrower joined with any Guarantor in any suit arising out of this Article VIII and/or the Obligations, or (v) pursue any other remedy in the Participants’ powers whatsoever. It is agreed between the Guarantors and the Participants that the foregoing waivers are of the essence of the transaction contemplated by this Agreement and the other Loan Documents and that, but for this Guaranty and such waivers, the Participants would not extend or continue to extend credit under this Agreement. The Participants shall not be required to mitigate damages or take any action to reduce, collect or enforce the Obligations. Guarantor waives any defense arising by reason of any disability, lack of corporate authority or power, or other defense of the Borrower or any other guarantor of the Obligations, and shall remain liable hereon regardless of whether the Borrower or any other guarantor be found not liable thereon for any reason. Whether and when to exercise any of the remedies of the Participants under any of the Loan Documents shall be in the sole and absolute discretion of the Administrative Agent, and no delay by the Administrative Agent in enforcing any remedy, including delay in conducting a foreclosure sale, shall be a defense to any Guarantor’s liability under this Article VIII.

(b) In addition to the waivers contained in Section 8.04(a) hereof, the Guarantors waive, and agree that they shall not at any time insist upon, plead or in any manner whatsoever claim or take the benefit or advantage of, any appraisal, valuation, stay, extension, marshaling of assets or redemption laws, or exemption, whether now or at any time hereafter in force, which may delay, prevent or otherwise affect the performance by the Guarantors of their obligations under, or the enforcement by any Agent or the Participants of, this Guaranty. The Guarantors hereby waive diligence, presentment and demand (whether for nonpayment or protest or of acceptance, maturity, extension of time, change in nature or form of the Obligations, acceptance of further security, release of further security, composition or agreement arrived at as to the amount of, or the terms of, the Obligations, notice of adverse change in the Borrower’s financial condition or any other fact which might materially increase the risk to the Guarantors) with respect to any of the Obligations or all other demands whatsoever and waive the benefit of all provisions of law which are or might be in conflict with the terms of this Article VIII. The Guarantors, jointly and severally, represent, warrant and agree that, as of the date of this Guaranty, their obligations under this Guaranty are not subject to any offsets or defenses of any kind against any Agent, the Participants, the Borrower or any other Person that executes a Loan Document. The Guarantors further jointly and severally agree that their obligations under this Guaranty shall not be subject to any counterclaims, offsets or defenses of any kind which may arise in the future against any Agent, the Participants, the Borrower or any other Person that executes a Loan Document.

(c) Subrogation. Until the Obligations have been paid in full, each Guarantor waives all rights of subrogation or reimbursement against the Borrower, whether arising by contract or operation of law (including, without limitation, any such right arising under any federal, state or other applicable bankruptcy or insolvency laws) and waives any right to enforce any remedy which the Participants now have or may hereafter have against the Borrower, and waives any benefit or any right to participate in any security now or hereafter held by the Administrative Agent or any Participant.

Section 8.05 Maturity of Obligations, Payment. Each Guarantor agrees that if the maturity of any of the Obligations is accelerated by bankruptcy or otherwise, such maturity shall also be deemed accelerated for the purpose of this Article VIII without demand or notice to any Guarantor. Each Guarantor will, forthwith upon notice from the Administrative Agent, jointly and severally pay to the Administrative Agent the amount due and unpaid by the Borrower and guaranteed hereby. The failure of the Administrative Agent to give this notice shall not in any way release any Guarantor hereunder.

Section 8.06 Agent’s Expenses. If any Guarantor fails to pay the Obligations after notice from the Administrative Agent of the Borrower’s failure to pay any Obligations at maturity, and if the Administrative Agent obtains the services of an attorney for collection of amounts owing by any Guarantor hereunder, or obtaining advice of counsel in respect of any of their rights under this Article VIII, or if suit is filed to enforce this Article VIII, or if proceedings are had in any bankruptcy, probate, receivership or other judicial proceedings for the establishment or collection of any amount owing by any Guarantor hereunder, or if any amount owing by any Guarantor hereunder is collected through such proceedings, each Guarantor jointly and severally agrees to pay to the Administrative Agent the Administrative Agent’s reasonable attorneys’ fees.

Section 8.07 Liability. It is expressly agreed that the liability of each Guarantor for the payment of the Obligations guaranteed hereby shall be primary and not secondary.

Section 8.08 Events and Circumstances Not Reducing or Discharging any Guarantor’s Obligations.

(i) The Participants shall first be entitled to receive payment in full in cash of the Obligations before the Borrower or any Guarantor is entitled to receive any payment on account of the Guarantor Claims.

(ii) Any payment or distribution of assets of any Loan Party of any kind or character, whether in cash, property or securities, to which the Borrower or any Guarantor would be entitled except for the provisions of this Section 8.09(c), shall be paid by the liquidating trustee or agent or other Person making such payment or distribution directly to the Participants, to the extent necessary to make payment in full of all Obligations remaining unpaid after giving effect to any concurrent payment or distribution or provisions therefor to the Participants.

(d) No right of the Participants or any other present or future holders of any Obligations to enforce the subordination provisions herein shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of any Loan Party or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Borrower or any Guarantor with the terms hereof, regardless of any knowledge thereof which any such holder may have or be otherwise charged with.

Section 8.10 Claims in Bankruptcy. In the event of receivership, bankruptcy, reorganization, arrangement, debtor’s relief, or other insolvency proceedings involving the Borrower or any Subsidiary of the Borrower, as debtor, the Participants shall have the right to prove their claim in any proceeding, so as to establish their rights hereunder and receive directly from the receiver, trustee or other court custodian, dividends and payments which would otherwise be payable upon Guarantor Claims. Each Guarantor hereby assigns such dividends and payments to the Participants. Should the Administrative Agent or any Participant receive, for application upon the Obligations, any such dividend or payment which is otherwise payable to any Guarantor, and which, as between the Borrower or any Subsidiary of the Borrower and any Guarantor, shall constitute a credit upon the Guarantor Claims, then upon payment in full of the Obligations, such Guarantor shall become subrogated to the rights of the Participants to the extent that such payments to the Participants on the Guarantor Claims have contributed toward the liquidation of the Obligations, and such subrogation shall be with respect to that proportion of the Obligations which would have been unpaid if the Administrative Agent or a Participant had not received dividends or payments upon the Guarantor Claims.

Section 8.11 Payments Held in Trust. In the event that notwithstanding Sections 8.09 and 8.10 above, any Guarantor should receive any funds, payments, claims or distributions which is prohibited by such Sections, such Guarantor agrees to hold in trust for the Participants an amount equal to the amount of all funds, payments, claims or distributions so received, and

agrees that it shall have absolutely no dominion over the amount of such funds, payments, claims or distributions except to pay them promptly to the Administrative Agent, and each Guarantor covenants promptly to pay the same to the Administrative Agent.

Section 8.12 Benefit of Guaranty. The provisions of this Article VIII are for the benefit of the Participants, their successors, and their permitted transferees, endorsees and assigns. In the event all or any part of the Obligations are transferred, endorsed or assigned by the Participants, as the case may be, to any Person or Persons in accordance with the terms of this Agreement, any reference to the “Participants” herein, as the case may be, shall be deemed to refer equally to such Person or Persons.

Section 8.13 Reinstatement. This Article VIII shall remain in full force and effect and continue to be effective in the event any petition is filed by or against the Borrower, any Guarantor or any other Loan Party for liquidation or reorganization, in the event that any of them becomes insolvent or makes an assignment for the benefit of creditors or in the event a receiver, trustee or similar Person is appointed for all or any significant part of any of their assets, and shall continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Obligations, or any part thereof, is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by the Participants, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Obligations shall be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

Section 8.14 Liens Subordinate. Each Guarantor agrees that any liens, security interests, judgment liens, charges or other encumbrances upon the Borrower’s or any Subsidiary of the Borrower’s assets securing payment of the Guarantor Claims shall be and remain inferior and subordinate to any liens, security interests, judgment liens, charges or other encumbrances upon the Borrower’s or any Subsidiary of the Borrower’s assets securing payment of the Obligations, regardless of whether such encumbrances in favor of any Guarantor, the Administrative Agent or the Participants presently exist or are hereafter created or attach.

Section 8.15 Guarantor’s Enforcement Rights. Without the prior written consent of the Participants, no Guarantor shall (a) exercise or enforce any creditor’s right it may have against the Borrower or any Subsidiary of the Borrower, or (b) foreclose, repossess, sequester or otherwise take steps or institute any action or proceeding (judicial or otherwise, including without limitation the commencement of or joinder in any liquidation, bankruptcy, rearrangement, debtor’s relief or insolvency proceeding) to enforce any lien, mortgages, deeds of trust, security interest, collateral rights, judgments or other encumbrances on assets of the Borrower or any Subsidiary of the Borrower held by Guarantor.

Section 8.16 Limitation. It is the intention of the Guarantors and each Secured Party that the amount of the Obligations guaranteed by each Guarantor shall be in, but not in excess of, the maximum amount permitted by fraudulent conveyance, fraudulent transfer and similar Legal Requirement applicable to such Guarantor. Accordingly, notwithstanding anything to the contrary contained in this Article VIII or in any other agreement or instrument executed in connection with the payment of any of the Obligations guaranteed hereby, the amount of the

Obligations guaranteed by a Guarantor under this Article VIII shall be limited to an aggregate amount equal to the largest amount that would not render such Guarantor’s obligations hereunder subject to avoidance under Section 548 of the United States Bankruptcy Code or any comparable provision of any other applicable law.

Section 8.17 Contribution Rights.

(a) To the extent that any payment is made under this Guaranty (a “Guarantor Payment”), by a Guarantor, which Guarantor Payment, taking into account all other Guarantor Payments then previously or concurrently made by all other Guarantors, exceeds the amount which such Guarantor would otherwise have paid if each Guarantor had paid the aggregate Obligations satisfied by such Guarantor Payment in the same proportion that such Guarantor’s Allocable Amount (as defined below) (in effect immediately prior to such Guarantor Payment) bore to the aggregate Allocable Amounts of all of the Guarantors in effect immediately prior to the making of such Guarantor Payment, then, following the date on which the Obligations shall be paid and satisfied in full and each Guarantor shall have performed all of its obligations hereunder, such Guarantor shall be entitled to receive contribution and indemnification payments from, and be reimbursed by, each of the other Guarantors for the amount of such excess, pro rata based upon their respective Allocable Amounts in effect immediately prior to such Guarantor Payment.

(b) As of any date of determination, the “Allocable Amount” of any Guarantor shall be equal to the maximum amount of the claim which could then be recovered from such Guarantor under this Guaranty without rendering such claim voidable or avoidable under Section 548 of Chapter 11 of the Bankruptcy Code or under any applicable state Uniform Fraudulent Transfer Act, Uniform Fraudulent Conveyance Act or similar statute or common law.

(c) This Section 8.17 is intended only to define the relative rights of the Guarantors and nothing set forth in this Section 8.17 is intended to or shall impair the obligations of the Guarantors, jointly and severally, to pay any amounts as and when the same shall become due and payable in accordance with the terms of this Guaranty.

(d) The rights of the parties under this Section 8.17 shall be exercisable upon the date the Obligations shall be paid and satisfied in full and each Guarantor shall have performed all of its obligations hereunder.

(e) The parties hereto acknowledge that the right of contribution and indemnification hereunder shall constitute assets of any Guarantor to which such contribution and indemnification is owing.

Section 8.18 Release of Guarantors. Upon the sale or disposition of any Guarantor pursuant to the terms of this Agreement to any Person other than the Borrower or any other Guarantor, the Administrative Agent shall, at the Borrower’ expense, execute and deliver to such Guarantor such documents as such Guarantor shall reasonably require and take any other actions reasonably required to evidence or effect the release of such Guarantor from this Agreement and the other Loan Documents.

Either Agent or the Issuing Bank may consult with legal counsel (who may be counsel for a Loan Party), 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.

Section 9.06 Resignation of an Agent, the Issuing Bank or the Revolving Loan Lender.

(a) An Agent may resign at any time by giving prior written notice thereof to the Participants and the Borrower, such resignation to be effective upon the appointment of a successor Administrative Agent, Collateral Agent or Deposit Bank or, if no successor Administrative Agent, Collateral Agent or Deposit Bank has been appointed, 45 days after the retiring Agent gives notice of its intention to resign. Upon any such resignation, the Majority Participants shall have the right to appoint, on behalf of the Borrower and the Participants, a successor Administrative Agent, Collateral Agent or Deposit Bank. If no successor Administrative Agent, Collateral Agent or Deposit Bank shall have been so appointed by the Majority Participants within 30 days after the resigning Agent’s giving notice of its intention to resign, then the resigning Agent may appoint, on behalf of the Borrower and the Participants, a successor Agent. If the Administrative Agent has resigned and no successor Administrative Agent has been appointed, the Majority Participants may perform all the duties of the Administrative Agent hereunder and the Borrower shall make all payments in respect of the Obligations to the applicable Participant and for all other purposes shall deal directly with the Majority Participants until such successor Administrative Agent shall have been appointed as provided herein. No successor Agent shall be deemed to be appointed hereunder until such successor Agent has accepted the appointment or, in the case of a successor Collateral Agent, upon the execution and filing or recording of such financing statements, or amendments thereto, and such amendments or supplements to the Security Documents, and such other instruments or notices, as may be necessary or desirable, or as the Majority Participants may request, in order to continue the perfection of the Liens granted or purported to be granted by the Security Documents. No successor Deposit Bank shall be deemed appointed until arrangements satisfactory to the Issuing Bank and the Majority Participants with respect to the custody and management of the Deposit Account have been entered into.

Upon the effectiveness of the resignation of the Administrative Agent, Collateral Agent or Deposit Bank, the resigning Agent shall be discharged from its duties and obligations hereunder and under the Credit Documents. After the effectiveness of the resignation of an Agent, the provisions of this Article IX shall continue in effect for the benefit of such Agent in respect of any actions taken or omitted to be taken by it while it was acting as an Agent hereunder and under the other Loan Documents.

No successor Issuing Bank shall be deemed to be appointed hereunder until such successor Issuing Bank has accepted the appointment. Any such successor Issuing Bank shall be a commercial bank having capital and retained earnings of at least $500,000,000 unless such requirement is waived by the Majority Participants and the Borrower.

After the effectiveness of the resignation of the Issuing Bank, the provisions of this Article IX shall continue in effect for the benefit of the Issuing Bank in respect of any actions taken or omitted to be taken by it while it was acting as the Issuing Bank hereunder and under the other Loan Documents.

(c) The Revolving Loan Lender may resign at any time by giving prior written notice thereof to the Participants and the Borrower, such resignation to be effective upon the appointment of a successor Revolving Loan Lender. Upon any such resignation, the Majority Participants shall have the right to appoint, on behalf of the Borrower and the Participants and after consultation with the Borrower, a successor Revolving Loan Lender.

Section 9.07 Non-Reliance on Administrative Agent and Other Participants. Each Participant and the Issuing Bank acknowledges that it has, independently and without reliance upon any Agent or any other Participant 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.

THE PARTICIPANTS SEVERALLY AGREE TO INDEMNIFY UPON DEMAND THE ADMINISTRATIVE AGENT, THE COLLATERAL AGENT, THE DEPOSIT BANK, THE REVOLVING LOAN LENDER, THE ISSUING BANK AND EACH RELATED PARTY OF ANY OF THE FOREGOING (TO THE EXTENT NOT REIMBURSED BY THE LOAN PARTIES), ACCORDING TO THEIR RESPECTIVE PRO RATA SHARES, AND HOLD HARMLESS SUCH INDEMNITEE FROM AND AGAINST ANY AND ALL INDEMNIFIED LIABILITIES IN ALL CASES, WHETHER OR NOT CAUSED BY OR ARISING, IN WHOLE OR IN PART, OUT OF THE NEGLIGENCE OF ANY RELATED PARTY; PROVIDED, HOWEVER THAT NO PARTICIPANT SHALL BE LIABLE FOR (A) THE PAYMENT TO ANY INDEMNITEE FOR ANY PORTION OF SUCH INDEMNIFIED LIABILITIES TO THE EXTENT DETERMINED IN A FINAL, NONAPPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED FROM SUCH INDEMNITEE’S OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT AND (B) CLAIMS MADE OR LEGAL PROCEEDINGS COMMENCED AGAINST SUCH INDEMNITEE BY ANY SECURITY HOLDER OR CREDITOR THEREOF ARISING OUT OF AND BASED ON RIGHTS AFFORDED ANY SUCH SECURITY HOLDER OR CREDITOR SOLELY IN ITS CAPACITY AS SUCH; PROVIDED FURTHER, HOWEVER, THAT NO ACTION TAKEN IN ACCORDANCE WITH THE DIRECTIONS OF THE MAJORITY PARTICIPANTS SHALL BE DEEMED TO CONSTITUTE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT FOR PURPOSES OF THIS SECTION.

THE UNDERTAKING IN THIS SECTION SHALL SURVIVE TERMINATION OF THE COMMITMENTS, THE PAYMENT OF ALL OTHER OBLIGATIONS AND THE RESIGNATION OF THE ADMINISTRATIVE AGENT OR THE COLLATERAL AGENT.

Section 9.09 Collateral and Guaranty Matters.

(a) The Participants irrevocably authorize the Collateral Agent, at its option and in its discretion, without the necessity of any notice to or further consent from the Secured Parties:

(i) to release any Lien on any property granted to or held by the Collateral Agent under any Security Document (i) upon termination of the Commitments and payment in full of all Obligations (other than contingent indemnification obligations) and the expiration or termination of all Letters of Credit, (ii) that is sold or to be sold as part of or in connection with any sale permitted hereunder or under any other Loan Document, or (iii) subject to Section 10.01, if approved, authorized or ratified in writing by the Majority Participants;

(ii) to take any actions with respect to any Collateral or Security Documents which may be necessary to perfect and maintain Acceptable Security Interests in and Liens upon the Collateral granted pursuant to the Security Documents; and

(b) Upon the request of the Collateral Agent at any time, the Participants will confirm in writing the Collateral Agent’s authority to release particular types or items of Collateral pursuant to this Section 9.09.

(c) Each Loan Party hereby irrevocably appoints the Collateral Agent as such Loan Party’s attorney-in-fact, with full authority to, after the occurrence and during the continuance of an Event of Default, act for such Loan Party and in the name of such Loan Party to, in the Collateral Agent’s discretion upon the occurrence and during the continuance of an Event of Default, (i) file one or more financing or continuation statements, and amendments thereto, relative to all or any part of the Collateral without the signature of such Loan Party where permitted by law, (ii) to receive, endorse, and collect any drafts or other instruments, documents, and chattel paper which are part of the Collateral, (iii) to ask, demand, collect, sue for, recover, compromise, receive, and give acquittance and receipts for moneys due and to become due under or in respect of any of the Collateral, (iv) to file any claims or take any action or institute any proceedings which the Collateral Agent may reasonably deem necessary or desirable for the collection of any of the Collateral or otherwise to enforce the rights of the Collateral Agent with respect to any of the Collateral and (v) if any Loan Party fails to perform any covenant contained in this Agreement or the other Security Documents after the expiration of any applicable grace periods, the Collateral Agent may itself perform, or cause performance of, such covenant, and such Loan Party shall pay for the expenses of the Collateral Agent incurred in connection therewith in accordance with Section 10.04. The power of attorney granted hereby is coupled with an interest and is irrevocable.

(d) The powers conferred on the Collateral Agent under this Agreement and the other Security Documents are solely to protect its interest in the Collateral and shall not impose any duty upon it to exercise any such powers. Beyond the safe custody thereof, the Collateral Agent

and each Participant shall have no duty with respect to any Collateral in its possession or control (or in the possession or control of any agent or bailee) or with respect to any income thereon or the preservation of rights against prior parties or any other rights pertaining thereto. The Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which the Collateral Agent accords its own property. None of the Administrative Agent, the Collateral Agent or any Participant shall be liable or responsible for any loss or damage to any of the Collateral, or for any diminution in the value thereof, by reason of the act or omission of any warehouseman, carrier, forwarding agency, consignee, broker or other agent or bailee selected by Borrower or selected by the Administrative Agent or the Collateral Agent in good faith.

Section 10.06 Successors and Assigns.

(a) Generally. The terms and provisions of this Agreement and the other Loan Documents shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that no Loan Party may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Participant and no Participant may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of subsection (b) of this Section, (ii) by way of participation in accordance with the provisions of subsection (d) of this Section, (iii) by way of pledge or assignment of a security interest subject to the restrictions of subsection (f) or (h) of this Section, or (iv) to an SPC in accordance with the provisions of subsection (g) of this Section (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 subsection (d) of this Section and, to the extent expressly contemplated hereby, the Indemnitees) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Assignments by Participants. Any Participant may assign to one or more Eligible Assignees all or any portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitments, the Advances and Deposits owing to it, and participations in Letter of Credit Obligations) at the time owing to it; provided, however, that

(i) except in the case of an assignment of the entire remaining amount of the assigning Participant’s Commitment and the Advances and Deposits owing to it or in the case of an assignment to a Participant or an Affiliate of a Participant or an Approved Fund with respect to a Participant, the aggregate amount of the Commitments and Advances of such Participant being assigned pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall not be less than $1,000,000;

(ii) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording in the Register, an Assignment and Acceptance; and

(iii) each Eligible Assignee (other than an Eligible Assignee that is a Participant or an Affiliate of a Participant) shall pay to the Administrative Agent a $3,500 processing and recording fee; provided, however that only one such fee shall be payable in the event of contemporaneous assignments to or by two or more Approved Funds.

Upon such execution, delivery, acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Acceptance, (A) the Eligible Assignee thereunder shall be a party hereto for all purposes and, to the extent that rights and obligations hereunder have been assigned to it

104

pursuant to such Assignment and Acceptance, have the rights and obligations of a Participant hereunder and (B) such assigning Participant thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of such Participant’s rights and obligations under this Agreement, such Participant shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 2.10, 2.12, 10.04 and 10.05 with respect to facts and circumstances occurring prior to the effective date of such assignment). Any assignment or transfer by a Participant of rights or obligations under this Agreement that does not comply with this subsection shall be treated for purposes of this Agreement as a sale by such Participant of a participation in such rights and obligations in accordance with subsection (d) of this Section.

(c) Register. The Administrative Agent shall maintain at its Applicable Lending Office a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the Participants and the Commitments of, and principal amount of the Advances and Deposits owing to, each Participant from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and each of the Loan Parties, the Administrative Agent, the Issuing Bank, and the Participants may treat each Person whose name is recorded in the Register as a Participant hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Participant at any reasonable time and from time to time upon reasonable prior notice.

(d) Participations. Any Participant may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Sub-Participant”) in all or a portion of such Participant’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Advances and Deposits (including such Participant’s participations in Letter of Credit Obligations) owing to it); provided that (i) such Participant’s obligations under this Agreement shall remain unchanged, (ii) such Participant shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the other Participants shall continue to deal solely and directly with such Participant in connection with such Participant’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Participant sells such a participation shall provide that such Participant 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 Participant will not, without the consent of the Sub-Participant, agree to any amendment, waiver or other modification described in the first proviso to Section 10.01 that directly affects such Sub-Participant. Subject to subsection (e) of this Section, the Borrower agrees that each Sub-Participant shall be entitled to the benefits of Sections 2.09, 2.10, 2.12, 10.04 and 10.05 to the same extent as if it were a Participant and had acquired its interest by assignment pursuant to subsection (b) of this Section. To the extent permitted by law, each Sub-Participant also shall be entitled to the benefits of Section 7.05 as though it were a Participant, provided such Sub-Participant agrees to be subject to Section 2.13 as though it were a Participant.

105

(e) A Sub-Participant shall not be entitled to receive any greater payment under Section 2.09 or 2.11 than the applicable Participant would have been entitled to receive with respect to the participation sold to such Sub-Participant, unless the sale of the participation to such Sub-Participant is made with the Borrower’ prior written consent. A Sub-Participant that would be a Foreign Participant if it were a Participant shall not be entitled to the benefits of Section 2.12 unless the Borrower are notified of the participation sold to such Sub-Participant and such Sub-Participant agrees, for the benefit of the Borrower, to comply with Section 2.12(e) as though it were a Participant.

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

(g) Notwithstanding anything to the contrary contained herein, any Participant (a “Granting Participant”) may grant to a special purpose funding vehicle identified as such in writing from time to time by the Granting Participant to the Administrative Agent and the Borrower (an “SPC”) the option to provide all or any part of any Advance or Deposit that such Granting Participant would otherwise be obligated to make pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to fund any Advance or Deposit, and (ii) if a SPC elects not to exercise such option or otherwise fails to make all or any part of such Advance or Deposit, the Granting Participant shall be obligated to make such Advance pursuant to the terms hereof. Each party hereto hereby agrees that (i) neither the grant to any SPC nor the exercise by any SPC of such option shall increase the costs or expenses or otherwise increase or change the obligations of the Borrower under this Agreement, (ii) no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Participant would be liable, and (iii) the Granting Participant shall for all purposes, including the approval of any amendment, waiver or other modification of any provision of any Loan Document, remain the lender of record hereunder. The making of an Advance or Deposit by a SPC hereunder shall utilize the Commitment of the Granting Participant to the same extent, and as if, such Advance or Deposit were made by such Granting Participant. In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior debt of any SPC, it will not institute against, or join any other Person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency, or liquidation proceeding under the laws of the United States or any State thereof. Notwithstanding anything to the contrary contained herein, any SPC may (i) with notice to, but without prior consent of the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or any portion of its right to receive payment with respect to any Advance to the Granting Participant and (ii) disclose on a confidential basis any non-public information relating to its funding of Advances to any rating agency, commercial paper dealer or provider of any surety or Guarantee or credit or liquidity enhancement to such SPC.

(h) Notwithstanding anything to the contrary contained herein, any Participant that is a Fund may create a security interest in all or any portion of the Advances owing to it and the

106

Note, if any, held by it to the trustee for holders of obligations owed, or securities issued, by such Fund as security for such obligations or securities, provided that unless and until such trustee actually becomes a Participant in compliance with the other provisions of this Section 10.06, (i) no such pledge shall release the pledging Participant from any of its obligations under the Loan Documents and (ii) such trustee shall not be entitled to exercise any of the rights of a Participant under the Loan Documents even though such trustee may have acquired ownership rights with respect to the pledged interest through foreclosure or otherwise.

Section 10.07 Confidentiality. Each of the Agents, the Issuing Bank and the Participants agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party hereto, (e) 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, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of, pledgee under Section 10.06(f) or Sub-Participant in, or any prospective assignee of, pledgee under Section 10.06(f) or Sub-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 Borrower and its obligations, (g) with the consent of the Borrower or (h) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section or (y) becomes available to the Administrative Agent or any Participant on a nonconfidential basis from a source other than the Borrower. For purposes of this Section, “Information” means all information received from any Loan Party relating to any Loan Party or any of their respective businesses, other than any such information that is available to an Agent, the Issuing Bank or any Participant on a nonconfidential basis prior to disclosure by any Loan Party, provided that, in the case of information received from a Loan Party after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

Section 10.08 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

Such representations and warranties have been or will be relied upon by the Agents,

107

the Issuing Bank and each Participant, regardless of any investigation made by any Agent, the Issuing Bank or any Participant or on their behalf and notwithstanding that any Agent, the Issuing Bank or any Participant may have had notice or knowledge of any Default at the time of any Advance, and shall continue in full force and effect as long as any Advance or any other Obligation hereunder shall remain unpaid or unsatisfied or any Letter of Credit shall remain outstanding.

Section 10.10 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.

Section 10.11 [Reserved].

Section 10.12 Governing Law. This Agreement and each of the other Loan Documents shall be governed by and construed in accordance with the laws of the State of New York and the applicable laws of the United States of America.

No Pledgor shall approve any amendment or modification of any of the Pledged Collateral unless it shall have given at least ten Business Days’ prior written notice (or such lesser period as may be agreed by the Collateral Agent in writing) to the Collateral Agent and such amendment or modification would not be materially adverse to the interests of the Secured Parties.

Exhibit H – Page 6

Section 5. Remedies upon Default. If any Event of Default shall have occurred and be continuing:

(a) UCC Remedies. To the extent permitted by law, the Collateral Agent may (and at the request of the Majority Participants shall) exercise in respect of the Pledged Collateral, in addition to other rights and remedies provided for in this Pledge Agreement or otherwise available to it, all the rights and remedies of a secured party under the UCC (whether or not the UCC applies to the affected Pledged Collateral). This Pledge Agreement shall not be construed to authorize the Collateral Agent to take any action prohibited by the UCC or to constitute a waiver by the Pledgor of any right that the UCC does not permit the Pledgor to waive.

(b) Dividends and Other Rights.

(i) All rights of Pledgor to exercise the voting and other consensual rights which it would otherwise be entitled to exercise pursuant to Section 2(d)(i) may be exercised by the Collateral Agent if the Collateral Agent so elects and gives written notice of such election to Pledgor and all rights of Pledgor to receive the dividends and other distributions on or in respect of the Pledged Collateral and the proceeds of sale of the Pledged Collateral which it would otherwise be authorized to receive and retain pursuant to Section 2(d)(ii) shall cease at such time as such written notice is deemed effective pursuant to the provisions of the Credit Agreement related to effectiveness of notices.

(ii) All dividends and other distributions on or in respect of the Pledged Collateral and the proceeds of sale of the Pledged Collateral that are thereafter received by Pledgor shall be received in trust for the benefit of the Collateral Agent, shall be segregated from other funds of Pledgor, and shall be promptly paid over to the Collateral Agent as Pledged Collateral in the same form as so received (with any necessary endorsement).

(c) Sale of Pledged Collateral. The Collateral Agent may sell all or part of the Pledged Collateral at public or private sale, at any of the Collateral Agent’s offices or elsewhere, for cash, on credit, or for future delivery, and upon such other terms as the Collateral Agent may deem commercially reasonable in accordance with applicable laws. Each Pledgor agrees that to the extent permitted by law such sales may be made without notice. If notice is required by law, each Pledgor hereby deems 10 days’ advance notice of the time and place of any public sale or the time after which any private sale is to be made reasonable notification, recognizing that if the Pledged Collateral threatens to decline speedily in value or is of a type customarily sold on a recognized market shorter notice may be reasonable. The Collateral Agent shall not be obligated to make any sale of the Pledged Collateral regardless of notice of sale having been given. The Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the

Exhibit H – Page 7

time and place to which it was so adjourned. Each Pledgor shall cooperate fully with the Collateral Agent in all respects in selling or realizing upon all or any part of the Pledged Collateral. In addition, each Pledgor shall fully comply with federal and state securities laws and take such actions as may be necessary to permit the Collateral Agent to sell or otherwise dispose of any securities representing the Pledged Collateral in compliance with such laws.

(d) Exempt Sale. If, in the opinion of the Collateral Agent, there is any question that a public or semipublic sale or distribution of any Pledged Collateral will violate any state or federal securities law, the Collateral Agent in its discretion (i) may offer and sell securities privately to purchasers who will agree to take them for investment purposes and not with a view to distribution and who will agree to the imposition of restrictive legends on any certificates representing the security, or (ii) may sell such securities in an intrastate offering under Section 3(a)(11) of the Securities Act of 1933, as amended, and no sale so made in good faith by the Collateral Agent shall be deemed to be not “commercially reasonable” solely because so made. Each Pledgor shall cooperate fully with the Collateral Agent in all reasonable respects in selling or realizing upon all or any part of the Pledged Collateral.

(e) Application of Collateral. The proceeds of any sale, or other realization upon all or any part of the Collateral pledged by each Pledgor shall be applied by the Collateral Agent as set forth in Section 7.06 of the Credit Agreement.

(f) Cumulative Remedies. Each right, power and remedy herein specifically granted to the Collateral Agent or otherwise available to it shall be cumulative, and shall be in addition to every other right, power and remedy herein specifically given or now or hereafter existing at law, in equity, or otherwise, and each such right, power and remedy, whether specifically granted herein or otherwise existing, may be exercised at any time and from time to time as often and in such order as may be deemed expedient by the Collateral Agent in its sole discretion. No failure on the part of the Collateral Agent to exercise, and no delay in exercising, and no course of dealing with respect to, any such right, power or remedy, shall operate as a waiver thereof, nor shall any single or partial exercise of any such rights, power or remedy preclude any other or further exercise thereof or the exercise of any other right.

Section 6. Collateral Agent as Attorney-in-Fact for Pledgors.

(a) Collateral Agent Appointed Attorney-in-Fact. Each Pledgor hereby irrevocably appoints the Collateral Agent as such Pledgor’s attorney-in-fact, with full authority after the occurrence and during the continuance of an Event of Default to act for such Pledgor and in the name of such Pledgor, and, in the Collateral Agent’s discretion, subject to such Pledgor’s revocable rights specified in Section 2(d), to take any action and to execute any instrument which the Collateral Agent may deem necessary or advisable to accomplish the purposes of this Pledge Agreement, including, without limitation, to receive, indorse, and collect all instruments made payable to the Pledgor representing the proceeds of the sale of the Pledged Collateral, or any distribution in respect of the Pledged Collateral and to give full discharge for the same. EACH

Exhibit H – Page 8

PLEDGOR HEREBY ACKNOWLEDGES, CONSENTS AND AGREES THAT THE POWER OF ATTORNEY GRANTED PURSUANT TO THIS SECTION IS IRREVOCABLE AND COUPLED WITH AN INTEREST.

(b) Collateral Agent May Perform. The Collateral Agent may from time to time, at its option and expense, perform any act which any Pledgor agrees hereunder to perform and which such Pledgor shall fail to perform after being requested in writing so to perform (it being understood that no such request need be given after the occurrence and during the continuance of any Event of Default and after notice thereof by the Collateral Agent to such Pledgor) and the Collateral Agent may from time to time take any other action which the Collateral Agent reasonably deems necessary for the maintenance, preservation or protection of any of the Pledged Collateral or of its security interest therein. The Collateral Agent shall be obligated to provide notice to such Pledgor of any action taken hereunder by telecopy or by registered mail.

(c) Collateral Agent Has No Duty. The powers conferred on the Collateral Agent hereunder are solely to protect its interest in the Pledged Collateral and shall not impose any duty on it to exercise any such powers. Except for reasonable care of any Pledged Collateral in its possession and the accounting for moneys actually received by it hereunder, the Collateral Agent shall have no duty as to any Pledged Collateral or responsibility for taking any necessary steps to preserve rights against prior parties or any other rights pertaining to any Pledged Collateral.

(d) Reasonable Care. The Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Pledged Collateral in its possession if the Pledged Collateral is accorded treatment substantially equal to that which the Collateral Agent accords its own property, it being understood that the Collateral Agent shall have no responsibility for (i) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders, or other matters relative to any Pledged Collateral, whether or not the Collateral Agent has or is deemed to have knowledge of such matters, or (ii) taking any necessary steps to preserve rights against any parties with respect to any Pledged Collateral.

Section 7. Miscellaneous.

(a) Expenses. Each Pledgor will upon demand pay to the Collateral Agent for its benefit and the benefit of the Secured Parties the amount of any reasonable out-of-pocket expenses, including the reasonable fees and disbursements of its counsel and of any experts, which the Collateral Agent and the Secured Parties may incur in connection with (i) the custody, preservation, use, or operation of, or the sale, collection, or other realization of, any of the Pledged Collateral, (ii) the exercise or enforcement of any of the rights of the Collateral Agent or any Secured Party hereunder, and (iii) the failure by any Pledgor to perform or observe any of the provisions hereof.

(b) Amendments, Etc. No amendment or waiver of any provision of this Pledge Agreement nor consent to any departure by any Pledgor herefrom shall be effective unless made in writing and authenticated by the Borrower, each Pledgor

Exhibit H – Page 9

affected thereby and the Collateral Agent. In addition, no such amendment or waiver shall be effective unless given or entered into with the necessary approvals of either the Majority Participants or all Participants as required under the terms of the Credit Agreement. Any such waiver or consent, whether by the Collateral Agent or the Collateral Agent and the Participants shall be effective only in the specific instance and for the specific purpose for which given.

(c) Addresses for Notices. All notices and other communications provided for hereunder shall be in the manner and to the addresses set forth in the Credit Agreement.

(d) Continuing Security Interest; Transfer of Interest. This Pledge Agreement shall create a continuing security interest in the Pledged Collateral and, unless expressly released by the Collateral Agent, shall (i) remain in full force and effect until the Secured Obligations (including all Letter of Credit Obligations) are fully satisfied, all Letters of Credit have terminated or expired, all obligations of the Issuing Bank and the Participants in respect of Letters of Credit have terminated or expired and the Commitments have terminated or expired, (ii) be binding upon the Pledgors, the Collateral Agent, the Secured Parties and their successors and assigns, and (iii) inure, together with the rights and remedies of the Collateral Agent hereunder, to the benefit of and be binding upon, the Collateral Agent, the Secured Parties and their respective successors, transferees, and assigns. Upon the payment in full and termination of the Secured Obligations, the security interest granted hereby shall terminate and all rights to the Pledged Collateral shall revert to the Pledgors to the extent such Pledged Collateral shall not have been sold or otherwise applied pursuant to the terms hereof. Without limiting the generality of the foregoing clause, when any Participant assigns or otherwise transfers any interest held by it under the Credit Agreement or other Loan Document to any other Person pursuant to the terms of the Credit Agreement or other Loan Document, that other Person shall thereupon become vested with all the benefits held by such Participant under this Pledge Agreement. Upon any such termination, the Collateral Agent will, at the Borrower’s expense, deliver all Pledged Collateral to the Borrower, execute and deliver to the Borrower such documents as the Borrower shall reasonably request and take any other actions reasonably requested to evidence or effect such termination.

(e) Waivers. Each Pledgor hereby waives:

(i) promptness, diligence, notice of acceptance, and any other notice with respect to any of the Secured Obligations and this Pledge Agreement;

(ii) any requirement that the Collateral Agent or any Secured Party protect, secure, perfect, or insure any Lien or any Property subject thereto or exhaust any right or take any action against any Pledgor or any other Person or any collateral; and

(iii) any duty on the part of the Collateral Agent to disclose to any Pledgor any matter, fact, or thing relating to the business, operation, or condition of such Pledgor and its respective assets now known or hereafter known by such Person.

Exhibit H – Page 10

(f) Severability. Wherever possible each provision of this Pledge Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Pledge Agreement shall be prohibited by or invalid under such law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Pledge Agreement.

(g) Choice of Law. This Pledge Agreement shall be governed by and construed and enforced in accordance with the laws of the state of New York, except to the extent that the validity or perfection of the security interests hereunder, or remedies hereunder, in respect of any particular Collateral are governed by the laws of a jurisdiction other than the state of New York.

(h) Counterparts. For the convenience of the parties, this Pledge Agreement may be executed in multiple counterparts, each of which for all purposes shall be deemed to be an original, and all such counterparts shall together constitute but one and the same Pledge Agreement.

(i) Reinstatement. If, at any time after the Secured Obligations (including all Letter of Credit Obligations) are fully satisfied, all Letters of Credit have terminated or expired, all obligations of the Issuing Bank and the Participants in respect of Letters of Credit have terminated or expired, the Commitments have terminated or expired and the termination of the Collateral Agent’s security interest, any payments on the Secured Obligations previously made by any Pledgor or any other Person must be disgorged by the Collateral Agent for any reason whatsoever, including, without limitation, the insolvency, bankruptcy or reorganization of such Pledgor or such Person, this Pledge Agreement and the Collateral Agent’s security interests herein shall be reinstated as to all disgorged payments as though such payments had not been made, and such Pledgor shall sign and deliver to the Collateral Agent all documents, and shall do such other acts and things, as may be necessary to reinstate and perfect the Collateral Agent’s security interest.

Such Grantor hereby ratifies each such financing statement and any and all financing statements filed prior to the date hereof by the Collateral Agent. Each Grantor’s jurisdiction of organization or incorporation is set forth on Schedule II hereto, and each Grantor will not change such jurisdiction of organization or incorporation unless it has taken such action (if any) as is necessary to cause the security interest of the Collateral Agent in the Collateral to continue to be perfected and has given thirty (30) days’ prior written notice thereof to the Collateral Agent. Any new jurisdiction of organization shall be within the United States of America for all Grantors which are currently organized in the United States of America.

(a) Further Documentation; Pledge of Instruments. At any time and from time to time, upon the written request of the Collateral Agent, and at the sole expense of such Grantor, such Grantor will promptly and duly execute and deliver any and all such further instruments, documents and agreements and take such further action as the Collateral Agent may reasonably deem desirable to obtain the full benefits of this Security Agreement and of the rights and powers herein granted, including, without limitation using its reasonable efforts to secure all consents and approvals necessary or appropriate for the assignment to the Collateral Agent of any License or Contract held by such Grantor or in which such Grantor has any rights not heretofore assigned, the filing of any financing or continuation statements under the UCC with respect to the liens and security interests granted hereby, transferring Collateral to the Collateral Agent’s possession (if a security interest in such Collateral can be perfected only by possession), placing the interest of the Collateral Agent as lienholder on the certificate of title of any vehicle and using its best efforts to obtain waivers of liens from landlords and mortgagees. Such Grantor hereby irrevocably makes, constitutes and appoints the Collateral Agent (and all Persons designated by the Collateral Agent for that purpose) as such Grantor’s true and lawful attorney, effective upon the failure or refusal of such Grantor, upon the Collateral Agent’s request, to execute and/or deliver to the Collateral Agent any financing statement, continuation statement, instrument, document, or agreement which the Collateral Agent may reasonably deem desirable to obtain the full benefits of this Security Agreement and of the rights and powers granted hereunder (herein, “Supplemental Documentation”), to sign such Grantor’s name on any such Supplemental Documentation and to deliver any such Supplemental Documentation to such Person as the Collateral Agent, in its sole discretion, shall elect. Such Grantor also hereby authorizes the Collateral Agent to file any financing or continuation statement relating to the Collateral without the signature of such Grantor to the extent permitted by applicable law. Such Grantor agrees that a carbon, photographic, photostatic, or other reproduction of this Security Agreement or of a financing statement is sufficient as a financing statement and may be filed by the Collateral Agent in any filing office.

To the extent Collateral Agent perfects its security interest in the Nigerian Operations and related assets, the Collateral Agent shall, upon the consumation of a sale of such assets permitted hereunder and under the Credit Agreement, provide a release of the same to Grantor upon the reasonable request of Grantor. All approvals to be delivered under this subsection (d) shall be delivered within five (5) Business Days after Collateral Agent’s receipt of notice of said proposed sale and any release shall be provided to an escrow or closing agent, if applicable, at or prior to closing provided Collateral Agent is given at least five (5) Business Days advance notice of said closing date.

(f) Continuous Perfection. Such Grantor will not change its name, identity or corporate structure in any manner which might make any financing or continuation statement filed in connection herewith seriously misleading within the meaning of Section 9-506 of the UCC (or any other then applicable provision of the UCC) unless such Grantor shall have given the Collateral Agent at least thirty (30) days’ prior written notice thereof and shall have taken all action (or made arrangements to take such action substantially simultaneously with such change if it is impossible to take such action in advance) necessary or reasonably requested by the Collateral Agent to amend such financing statement or continuation statement so that it is not seriously misleading.

(b) The Collateral Agent agrees that, except upon the occurrence and during the continuation of an Event of Default, it will not exercise the power of attorney or any rights granted to the Collateral Agent pursuant to this Section 8 except for the rights granted under clause (ii) of paragraph (a) above. Each Grantor hereby ratifies, to the extent permitted by law, all that said attorneys shall lawfully do or cause to be done by virtue hereof. THE POWER OF ATTORNEY GRANTED PURSUANT TO THIS SECTION 8 IS A POWER COUPLED WITH AN INTEREST AND SHALL BE IRREVOCABLE.

(c) The powers conferred on the Collateral Agent hereunder are solely to protect the Collateral Agent’s interests in the Collateral and shall not impose any duty upon it to exercise any such powers. The Collateral Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers and neither it nor any of its affiliates, officers, directors, employees or agents shall be responsible to any Grantor for any act or failure to act, except for its own gross negligence or willful misconduct.

(d) Each Grantor also authorizes the Collateral Agent, at any time and from time to time upon the occurrence and during the continuation of any Event of Default, (i) to communicate in its own name with any party to any Contract with regard to the assignment of the right, title and interest of such Grantor in and under the Contracts hereunder and other matters relating thereto and (ii) to execute, in connection with the sale provided for in Section 10 hereof, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral.

Section 9. Performance by the Collateral Agent of Grantor’s Obligations. If any Grantor fails to perform or comply with any of its agreements contained herein and the Collateral Agent, as provided for by the terms of this Security Agreement, shall itself perform or comply, or otherwise cause performance or compliance, with such agreement, the reasonable expenses of the Collateral Agent incurred in connection with such performance or compliance, together with interest thereon at the rate then in effect in respect of Base Rate Advances, shall be payable by each Grantor to the Collateral Agent on demand and shall constitute Secured Obligations secured hereby.

Exhibit I – Page 16

Section 10. Remedies and Rights Upon Default. (a) If an Event of Default shall occur and be continuing, the Collateral Agent may exercise in addition to all other rights and remedies granted to it in this Security Agreement and in any other instrument or agreement securing, evidencing or relating to the Secured Obligations, all rights and remedies of a secured party under the UCC. Without limiting the generality of the foregoing, each Grantor expressly agrees that in any such event the Collateral Agent, without demand of performance or other demand, advertisement or notice of any kind (except the notice specified below of time and place of public or private sale) to or upon such Grantor or any other person (all and each of which demands, advertisements and/or notices are hereby expressly waived to the maximum extent permitted by the UCC and other applicable law), may forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give an option or options to purchase, or sell or otherwise dispose of and deliver said Collateral (or contract to do so), or any part thereof, in one or more parcels at public or private sale or sales, at any exchange or broker’s board or at any of the Collateral Agent’s offices or elsewhere at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Collateral Agent shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of said Collateral so sold, free of any right or equity of redemption, which equity of redemption each Grantor hereby releases. Each Grantor further agrees, at the Collateral Agent’s request, to assemble the Collateral and make it available to the Collateral Agent at places which the Collateral Agent shall reasonably select, whether at such Grantor’s premises or elsewhere. The Collateral Agent shall have no obligation to clean-up or prepare the Collateral for sale. The Collateral Agent shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, as provided in Section 7.06 of the Credit Agreement. Each Grantor shall remain liable for any deficiency remaining unpaid after such application, and only after so paying over such net proceeds and after the payment by the Collateral Agent of any other amount required by any provision of law, including Sections 9-610 and 9-615 of the UCC, need the Collateral Agent account for the surplus, if any, to any Grantor. To the maximum extent permitted by applicable law, Grantor waives all claims, damages, and demands against the Collateral Agent arising out of the repossession, retention or sale of the Collateral except such as arise out of the gross negligence or willful misconduct of the Collateral Agent. Each Grantor agrees that the Collateral Agent need not give more than ten (10) days’ notice (which notification shall be deemed given when mailed or delivered on an overnight basis, postage prepaid, addressed to such Grantor at its address for notices referred to in Section 14 hereof) of the time and place of any public sale or of the time after which a private sale may take place and that such notice is reasonable notification of such matters. The Collateral Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and any such sale may, without further notice, be made at the time and place to which it was adjourned. Each Grantor agrees that it would not be commercially unreasonable for the Collateral Agent to dispose of the Collateral or any portion thereof by using Internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capability of doing so, or that match buyers and sellers of assets.

Exhibit I – Page 17

(b) Each Grantor also agrees to pay all reasonable costs of the Collateral Agent, including, without limitation, attorneys’ fees, incurred in connection with the enforcement of any of its rights and remedies hereunder.

(c) Each Grantor hereby waives presentment, demand, protest or any notice (to the maximum extent permitted by applicable law) of any kind in connection with this Security Agreement or any Collateral, except for any notices which are expressly required to be given under the Credit Agreement or hereunder.

(d) The Collateral Agent may sell the Collateral without giving any warranties as to the Collateral. The Collateral Agent may disclaim or modify any warranties of title or the like. This procedure will not be considered to adversely affect the commercial reasonableness of any sale of the Collateral.

(e) The Collateral Agent and its agents may enter upon and occupy any real property owned or leased by any Grantor in order to exercise any of the Collateral Agent’s rights and remedies under this Agreement, without any obligation to such Grantor in respect of such entry or occupation.

(f) The Collateral Agent may comply with any applicable Requirement of Law in connection with a disposition of the Collateral or any part thereof and such compliance will not be considered adversely to affect any sale of the Collateral or any part thereof.

(g) The Collateral Agent shall have no duty to marshal any of the Collateral.

(h) If the Collateral Agent sells any of the Collateral on credit, the Grantor will be credited only with cash payments actually made by the purchaser and received by the Collateral Agent and applied to the indebtedness of the purchaser. In the event the purchaser fails to pay for the Collateral, the Collateral Agent may resell the Collateral and the Grantor shall be credited with the proceeds of sale.

(i) Each Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of Collateral are insufficient to pay in full the Secured Obligations.

Section 11. Grant of License to Use Patent and Trademark Collateral. For the purpose of enabling the Collateral Agent to exercise rights and remedies under Section 10 hereof at such time as the Collateral Agent, without regard to this Section 11, shall be lawfully entitled to exercise such rights and remedies, each Grantor hereby grants to the Collateral Agent an irrevocable, non-exclusive license (exercisable without payment of royalty or other compensation to such Grantor) to use, license or sublicense any Patent or Trademark, now owned or hereafter acquired by such Grantor, and wherever the same may be located, and including, without limitation, in such license reasonable access to all media in which any of the licensed items may be recorded or stored and to all computer and automatic machinery software and programs used for the compilation or printout thereof.

Section 12. Limitation on the Collateral Agent’s Duty in Respect of Collateral. The Collateral Agent shall not have any duty as to any Collateral in its possession or control or in the possession or control of any agent or nominee of it or any income thereon or as to the

Exhibit I – Page 18

preservation of rights against prior parties or any other rights pertaining thereto, except that the Collateral Agent shall use reasonable care with respect to the Collateral in its possession or under its control. The Collateral Agent shall account to each Grantor for any moneys received by it in respect of any foreclosure on or disposition of the Collateral.

Section 13. Term of Agreement; Reinstatement. This Agreement and the security interests granted hereunder shall remain in full force and effect until the Secured Obligations (including all Letter of Credit Obligations) are fully satisfied, all Letters of Credit have terminated or expired, all obligations of the Issuing Bank and the Participants in respect of Letters of Credit have terminated or expired and the Commitments have terminated or expired (except for any Obligations designated under the Credit Agreement as surviving the payment of all other Obligations or any termination of the Credit Agreement). Further, this Agreement shall remain in full force and effect and continue to be effective should any petition be filed by or against any Grantor for liquidation or reorganization, should any Grantor become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of any Grantor’s assets, and shall continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Secured Obligations, or any part thereof, is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee of the Secured Obligations, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Secured Obligations shall be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

Section 14. Notices. Except as otherwise provided herein, whenever it is provided herein that any notice, demand, request, consent, approval, declaration or other communication shall or may be given to or served upon any of the parties by any other party, or whenever any of the parties desires to give or serve upon any other party any other communication with respect to this Security Agreement, each such notice, demand, request, consent, approval, declaration or other communication shall be in writing and shall be delivered in the manner and to the addresses set forth in Section 10.02 of the Credit Agreement.

Section 15. Severability. Any provision of this Security Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

Section 16. No Waiver; Cumulative Remedies. The Collateral Agent shall not by any act, delay, omission or otherwise be deemed to have waived any of its rights or remedies hereunder, and no waiver shall be valid unless in writing, signed by the Collateral Agent, and then only to the extent therein set forth. A waiver by the Collateral Agent of any right or remedy hereunder on any one occasion shall not, unless and except to the extent (if any) otherwise expressly provided therein, be construed as a bar to any right or remedy which the Collateral Agent would otherwise have had on any future occasion. No failure to exercise nor any delay in exercising on the part of the Collateral Agent, any right, power or privilege hereunder, shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or

Exhibit I – Page 19

privilege hereunder preclude any other or future exercise thereof or the exercise of any other right, power or privilege. The rights and remedies hereunder provided are cumulative and may be exercised singly or concurrently, and are not exclusive of any rights and remedies provided by law.

Section 17. Successor and Assigns; Governing Law.

(a) This Security Agreement and all obligations of each Grantor hereunder shall be binding upon the successors and assigns of each Grantor, and shall, together with the rights and remedies of the Collateral Agent hereunder, inure to the benefit of the Collateral Agent, the Secured Parties and their respective successors and assigns; provided, however, that none of the Grantors may assign or delegate any of their rights or obligations under this Security Agreement without the prior written consent of the Collateral Agent. No sales of participations, other sales, assignments, transfers or other dispositions of any agreement governing or instrument evidencing the Secured Obligations or any portion thereof or interest therein shall in any manner affect the security interest granted to the Collateral Agent hereunder.

(b) THIS SECURITY AGREEMENT SHALL BE GOVERNED BY, AND BE CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, EXCEPT AS OTHERWISE SET FORTH IN THE DEFINITION OF “UCC” CONTAINED HEREIN.

Section 18. Use and Protection of Patent and Trademark Collateral. Notwithstanding anything to the contrary contained herein, unless an Event of Default has occurred and is continuing, the Collateral Agent shall from time to time execute and deliver, upon the written request of any Grantor, any and all instruments, certificates or other documents, in the form so requested, necessary or appropriate in the judgment of Grantor to permit Grantor to continue to exploit, license, use, enjoy and protect the Patents and Trademarks.

Section 19. Further Indemnification. EACH GRANTOR AGREES TO PAY, AND TO SAVE THE COLLATERAL AGENT HARMLESS FROM, ANY AND ALL LIABILITIES WITH RESPECT TO, OR RESULTING FROM ANY DELAY IN PAYING, ANY AND ALL EXCISE, SALES OR OTHER SIMILAR TAXES WHICH MAY BE PAYABLE OR DETERMINED TO BE PAYABLE WITH RESPECT TO ANY OF THE COLLATERAL OR IN CONNECTION WITH ANY OF THE TRANSACTIONS CONTEMPLATED BY THIS SECURITY AGREEMENT.

Section 20. Subagents. Anything contained herein to the contrary notwithstanding, the Collateral Agent may from time to time, when the Collateral Agent deems it to be necessary, appoint one or more subagents (each a “Subagent”) for the Collateral Agent hereunder with respect to all or any part of the Collateral. In the event that the Collateral Agent so appoints any Subagent with respect to any Collateral, (a) the assignment and pledge of such Collateral and the security interest granted in such Collateral by each Grantor hereunder shall be deemed for purposes of this Agreement to have been made to such Subagent, in addition to the Collateral Agent, for the benefit of the Collateral Agent and the Secured Parties, as security for the Secured Obligations, (b) such Subagent shall automatically be vested, in addition to the Collateral Agent, with all rights, powers, privileges, interests and remedies of the Collateral Agent hereunder with

Exhibit I – Page 20

respect to such Collateral, and (c) the term “Agent,” when used herein in relation to any rights, powers, privileges, interests and remedies of the Collateral Agent with respect to such Collateral, shall include such Subagent; provided, however, that no such Subagent shall be authorized to take any action with respect to any such Collateral unless and except to the extend expressly authorized in writing by the Collateral Agent.

Section 21. Amendments, Etc. No amendment or waiver of any provision of this Security Agreement nor consent to any departure by any Grantor herefrom shall be effective unless made in writing and authenticated by the Borrower, each Grantor affected thereby and the Collateral Agent. In addition, no such amendment or waiver shall be effective unless given or entered into with the necessary approvals of either the Majority Participants or all Participants as required under the terms of the Credit Agreement. Any such waiver or consent, whether by the Collateral Agent or the Collateral Agent and the Participants shall be effective only in the specific instance and for the specific purpose for which given.

Section 22. Integration. THIS WRITTEN AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT OF THE GRANTORS AND THE COLLATERAL AGENT WITH RESPECT TO THE SUBJECT MATTER HEREOF, AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.
