“Acquiring Person” has the meaning set forth in Section 5.20.

“Additional JV Debt” means Debt incurred by Equistar after the Closing Date in connection with the admission into such Borrower Joint Venture of a new partner or member, as the case may be; provided that, at the time such Debt is incurred, such Borrower Joint Venture’s ratio of Debt to EBITDA, calculated on a pro forma basis (without giving effect to anticipated expense reductions or other synergies) for its then most recent fiscal year for which financial statements are available, does not exceed 2.25:1.00.

“Additional Secured Obligations” has the meaning set forth in the Security Agreement and the Pledge Agreement.

“Adjusted EBITDA” means, for any period, the sum of (i) the EBITDA of the Non-JV Group for such period, adjusted to exclude the effect of one time charges incurred by the Non-JV Group in connection with (A) a TDI Sale, (B) the payment required to be made by LCR in connection with the LCR Acquisition upon the termination of the crude oil supply agreement to which it is a party, in an aggregate amount not exceeding $176,250,000 and (C) other cash restructuring charges in an aggregate amount not exceeding $50,000,000, plus (ii) the Distributed Cash Flow of all Borrower Joint Ventures and non-wholly owned Subject Assets Transferees for such period.

As used herein, the term “control” means possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of a Person, whether through the ownership of voting securities, by contract or otherwise. No director or officer of the Borrower shall be considered an Affiliate solely by virtue of holding such position.

“Applicable Lending Office” means, with respect to any Lender, (i) in the case of its Base Rate Loans, its Domestic Lending Office and (ii) in the case of its Euro-Dollar Loans, its Euro-Dollar Lending Office.

“Applicable Margin” means, with respect to Loans of any Type and any Class at any time, the percentage rate per annum set forth below as the Margin with respect to Loans of such Type and Class which is applicable at such time; provided that the Applicable Margin on any date shall be the sum of the percentage so determined plus 2.00%, if on such date (i) an Event of Default exists and (ii) except in the case of an Event of Default under Section 6.01(a), 6.01(b), 6.01(h), or 6.01(i), the Administrative Agent shall have notified the Borrower at the request of the Required Lenders that this proviso shall be applicable.

A. Revolving Loans. The Applicable Margin for Euro-Dollar Revolving Loans and Base Rate Revolving Loans for any day are the respective percentages set forth in the chart below in the applicable row and column based upon the Status that exists on such day.

B. Initial Term Loans. The Applicable Margin for the Initial Term Loans shall be 1.00% for Base Rate Loans and 2.00% for Euro-Dollar Loans; provided that in the event any Incremental Term Loans are borrowed with Applicable Margins which exceed those specified above by more than 0.25% per annum, the Applicable Margin for the Initial Term Loans shall be increased so as to be exactly 0.25% per annum less than the Applicable Margins applicable to such Incremental Term Loans. For this purpose, front-end fees or original issue discount with respect to Incremental Term Loans shall be equated to additional margin on the basis of an assumed four-year average life to maturity (i.e., 1.00% in front-end fees and/or original issue discount equals 0.25% additional margin).

The Term Commitments shall terminate upon the making of the Initial Term Loans on the Closing Date (unless earlier terminated in accordance with the other provisions of this Agreement).

(c) Incremental Term Loans. Term Loans in an aggregate principal amount of up to $500,000,000 may be borrowed hereunder pursuant to one or more Term Loan Supplements and may share pari passu in the Collateral; provided that (i) Term Loan Lenders reasonably acceptable to the Administrative Agent are willing to provide such Term Loans, (ii) such Term Loans mature no earlier than August 16, 2014, (iii) the Net Cash Proceeds received from the incurrence of such Term Loans shall be used to redeem Senior Notes that mature

Unless the Administrative Agent determines that any applicable condition specified in Article 3 has not been satisfied, the Administrative Agent will make the funds so received from the Lenders available to the Borrower at the Administrative Agent’s aforesaid address.

(c) Unless the Administrative Agent shall have received notice from a Lender before the date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available to the Administrative Agent on the date of such Borrowing in accordance with Section 2.03(b) and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made such share available to the Administrative Agent, such Lender and the Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) if such amount is repaid by the Borrower, a rate per annum equal to the higher of the Federal Funds Rate and the interest rate applicable to such Borrowing pursuant to Section 2.05 and (ii) if such amount is repaid by such Lender, the Federal Funds Rate.

(b) Each Euro-Dollar Loan shall bear interest on the outstanding principal amount thereof, for each day during each Interest Period applicable thereto, at a rate per annum equal to the sum of the Applicable Margin for such day plus the London Interbank Offered Rate applicable to such Interest Period.

In the event that such rate is not available at such time for any reason, then the “London Interbank Offered Rate” applicable to such Interest Period shall be the rate at which dollar deposits of $5,000,000 and for a maturity comparable to such Interest Period are offered by the principal London office of the Administrative Agent in immediately available funds in the London interbank market at approximately 11:00 A.M., London time, two Euro-Dollar Business Days prior to the commencement of such Interest Period.

(c) Any overdue principal of or interest on any Euro-Dollar Loan shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the higher of (i) the sum of the Applicable Margin for such day plus the London Interbank Offered Rate applicable to such Loan on the day before such payment was due and (ii) the rate applicable to overdue Base Rate Loans of such Class for such day.

(i) if such Loans are Base Rate Loans, the Borrower may elect to convert such Loans to Euro-Dollar Loans as of any Euro-Dollar Business Day; and

(ii) if such Loans are Euro-Dollar Loans, the Borrower may elect to convert such Loans to Base Rate Loans as of any Domestic Business Day or elect to continue such Loans as Euro-Dollar Loans for an additional Interest Period, subject to Section 2.11 if any such conversion is effective on any day other than the last day of an Interest Period applicable to such Loans.

Each such election shall be made by delivering a notice (a “Notice of Interest Rate Election”) to the Administrative Agent not later than 11:30 A.M. (New York City time) on the third Euro-Dollar Business Day before the conversion or continuation selected in such notice is to be effective. A Notice of Interest Rate Election may, if it so specifies, apply to only a portion of the aggregate principal amount of the relevant Group of Loans; provided that (i) such portion is allocated ratably among the Loans comprising such Group and (ii) the portion to which such Notice applies, and the remaining portion to which it does not apply, are each at least $10,000,000 (unless such portion is comprised of Base Rate Loans). If no such notice is timely received before the end of an Interest Period for any Group of Euro-Dollar Loans, the Borrower shall be deemed to have elected that such Group of Loans be converted to Base Rate Loans at the end of such Interest Period.

(b) Each Notice of Interest Rate Election shall specify:

(ii) the date on which the conversion or continuation selected in such notice is to be effective, which shall comply with the applicable clause of subsection (a) above;

Each Interest Period specified in a Notice of Interest Rate Election shall comply with the provisions of the definition of Interest Period.

(c) Promptly after receiving a Notice of Interest Rate Election from the Borrower pursuant to subsection (a) above, the Administrative Agent shall notify each Lender of the contents thereof and such notice shall not thereafter be revocable by the Borrower.

(d) The Borrower shall not be entitled to elect to convert any Loans to, or continue any Loans for an additional Interest Period as, Euro-Dollar Loans if (i) the aggregate principal amount of any Group of Euro-Dollar Loans created or continued as a result of such election would be less than $10,000,000 or (ii) a Default shall exist when the Borrower delivers notice of such election to the Administrative Agent.

Such commitment fee shall accrue from and including the date hereof to but excluding the date of termination of the Revolving Commitments in their entirety.

(b) The Borrower shall pay to the Administrative Agent (i) for the account of the Revolving Lenders ratably a letter of credit fee accruing daily on the aggregate undrawn amount of all outstanding Letters of Credit at a rate per annum equal to the Applicable Margin for Revolving Euro-Dollar Loans for such day and (ii) for the account of each Issuing Bank a letter of credit fronting fee accruing daily on the aggregate amount then available for drawing under all Letters of Credit issued by such Issuing Bank at a rate per annum mutually agreed between the Borrower and such Issuing Bank from time to time.

The Administrative Agent will promptly distribute to each Lender its ratable share of each such payment received by the Administrative Agent for the account of the Lenders. Whenever any payment of principal of, or interest on, the Base Rate Loans, of Letter of Credit Liabilities or interest thereon or of fees hereunder shall be due on a day which is not a Domestic Business Day, the date for payment thereof shall be extended to the next succeeding Domestic Business Day.

(b) Unless the Borrower notifies the Administrative Agent before the date on which any payment is due to the Lenders hereunder 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 on such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent that the Borrower shall not have so made such payment, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate.

demand for any resulting loss or expense incurred by it (or by a Participant in the related Loan), including (without limitation) any loss incurred in obtaining, liquidating or employing deposits from third parties, but excluding loss of margin for the period after such payment or conversion or failure to borrow, prepay, convert or continue; provided that such Lender shall have delivered to the Borrower a certificate setting forth in reasonable detail the calculation of the amount of such loss or expense, which certificate shall be conclusive in the absence of manifest error.

Section 2.12. Computation of Interest and Fees. Interest based on the Prime Rate hereunder shall be computed on the basis of a year of 365 days (or 366 days in a leap year) and paid for the actual number of days elapsed (including the first day but excluding the last day). All other interest and fees shall be computed on the basis of a year of 360 days and paid for the actual number of days elapsed (including the first day but excluding the last day).

Section 2.13. Notes. (a) If a Lender so requests in writing, the Borrower’s obligation to repay the Loans of such Lender shall be evidenced by a single Note payable to the order of such Lender for the account of its Applicable Lending Office.

(b) Each Lender may, by notice to the Borrower and the Administrative Agent, request that the Borrower’s obligation to repay such Lender’s Loans of a particular Type or Class be evidenced by a separate Note. Each such Note shall be in substantially the form of Exhibit A hereto with appropriate modifications to reflect the fact that it relates solely to Loans of the relevant Type or Class. Each reference in this Agreement to the “Note” of such Lender shall be deemed to refer to and include any or all of such Notes, as the context may require.

(c) Promptly after it receives any Lender’s Note pursuant to Article 3, the Administrative Agent shall forward such Note to such Lender. Each Lender shall record the date, amount, Class and Type of each Loan made by it and the date and amount of each payment of principal made by the Borrower with respect thereto, and may, if such Lender so elects in connection with any transfer or enforcement of its Note, endorse on the schedule forming a part thereof appropriate notations to evidence the foregoing information with respect to each such Loan then outstanding; provided that a Lender’s failure to make (or any error in making) any such recordation or endorsement shall not affect the Borrower’s obligations hereunder or under the Notes. Each Lender is hereby irrevocably authorized by the Borrower so to endorse its Note and to attach to and make a part of its Note a continuation of any such schedule as and when required.

Section 2.14. Registry. The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain a register (the “Register”) on which it will record the name and Commitment of each Lender, each Loan made by such Lender and each repayment of any Loan made by such Lender. With respect to

any Lender, the assignment or other transfer of the Commitments of such Lender and the rights to the principal of, and interest on, any Loan made and Note issued pursuant to this Agreement shall not be effective until such assignment or other transfer is recorded on the Register and otherwise complies with Section 9.06(c). Upon receipt of a properly executed and delivered Assignment and Assumption Agreement referred to in Section 9.06(c), the Administrative Agent shall accept such Assignment and Assumption Agreement and record such assignment or other transfer of all or part of any Commitments, Loans and Notes for a Lender on the Register. The Register shall be available at the offices where kept by the Administrative Agent for inspection by the Borrower and any Lender at any reasonable time upon reasonable prior notice to the Administrative Agent. Each Lender shall record on its internal records (including computerized systems) the foregoing information as to its own Commitments and Loans. Failure to make any such recordation, or any error in such recordation, shall not affect the obligations of any Obligor under the Loan Documents.

Section 2.15. Regulation D Compensation. If and so long as a reserve requirement of the type described in the definition of “Euro-Dollar Reserve Percentage” is prescribed by the Board of Governors of the Federal Reserve System (or any successor), each Lender subject to such requirement may require the Borrower to pay, contemporaneously with each payment of interest on each of such Lender’s Euro-Dollar Loans, additional interest on such Euro-Dollar Loan at a rate per annum determined by such Lender up to but not exceeding the excess of (i) (A) the applicable London Interbank Offered Rate divided by (B) one minus the Euro-Dollar Reserve Percentage over (ii) the applicable London Interbank Offered Rate. Any Lender wishing to require payment of such additional interest (x) shall so notify the Borrower and the Administrative Agent, in which case such additional interest on the Euro-Dollar Loans of such Lender shall be payable to such Lender at the place indicated in such notice with respect to each Interest Period commencing at least three Euro-Dollar Business Days after such Lender gives such notice and (y) shall notify the Borrower at least five Euro-Dollar Business Days before each date on which interest is payable on the Euro-Dollar Loans of the amount then due it under this Section. It is understood that (x) no additional interest is payable under this Section in respect of Euro-Dollar Loans not paid when due and (y) amounts claimed by any Lender under this Section shall be based on an assumed level of reserves maintained by it which is consistent with such Lender’s good faith estimate of the actual level at which the related reserves are required to be maintained by it over time.

Section 2.16. Letters of Credit. (a) Commitment to Issue Letters of Credit. (i) Subject to the terms and conditions hereof, and so long as no Stop Issuance Notice is in effect, each Issuing Bank agrees to issue Letters of Credit from time to time before the Letter of Credit Termination Date upon the request of the Borrower; provided that, immediately after each Letter of Credit is issued (i) the aggregate amount of the Revolving Outstandings shall not exceed the

aggregate amount of the Revolving Commitments and (ii) the aggregate amount of the Letter of Credit Liabilities shall not exceed $400,000,000. Upon the date of issuance by an Issuing Bank of a Letter of Credit, the Issuing Bank shall be deemed, without further action by any party hereto, to have sold to each Revolving Lender, and each Revolving Lender shall be deemed, without further action by any party hereto, to have purchased from the Issuing Bank, a participation in such Letter of Credit and the related Letter of Credit Liabilities in the proportion its respective Revolving Commitment bears to the aggregate Revolving Commitments.

(ii) On the Closing Date, without further action by any party hereto, each Issuing Bank that has issued an Existing Letter of Credit shall be deemed to have granted to each Revolving Lender, and each Revolving Lender shall be deemed to have acquired from such Issuing Bank, a participation in each Existing Letter of Credit and the related Letter of Credit Liabilities in the proportion its respective Revolving Commitment bears to the aggregate Revolving Commitments, all on the same terms and conditions as if such Existing Letters of Credit had been issued on the Closing Date pursuant to Section 2.16(a)(i).

(b) Method for Issuance; Terms; Extensions. (i) The Borrower shall give the Issuing Bank notice at least five Domestic Business Days (or such shorter notice as may be acceptable to the Issuing Bank in its discretion) prior to the requested issuance of a Letter of Credit specifying the date such Letter of Credit is to be issued, and describing the terms of such Letter of Credit and the nature of the transactions to be supported thereby (such notice, including any such notice given in connection with the extension of a Letter of Credit, a “Notice of Issuance”). Upon receipt of a Notice of Issuance, the Issuing Bank shall promptly notify the Administrative Agent, and the Administrative Agent shall promptly notify each Revolving Lender of the contents thereof and of the amount of such Lender’s participation in such Letter of Credit.

(ii) The issuance by the Issuing Bank of each Letter of Credit shall, in addition to the conditions precedent set forth in Section 3.02, be subject to the conditions precedent that such Letter of Credit shall be in such form and contain such terms as shall be reasonably satisfactory to the Issuing Bank and that the Borrower shall have executed and delivered such other instruments and agreements relating to such Letter of Credit as the Issuing Bank shall have reasonably requested. The Borrower shall also pay to the Issuing Bank for its own account issuance, drawing, amendment and extension charges in the amounts and at the times as agreed between the Borrower and the Issuing Bank.

(iii) The extension or renewal of any Letter of Credit shall be deemed to be an issuance of such Letter of Credit, and if any Letter of Credit contains a provision pursuant to which it is deemed to be extended

unless notice of termination is given by the Issuing Bank, the Issuing Bank shall timely give such notice of termination unless it has theretofore timely received a Notice of Issuance and the other conditions to issuance of a Letter of Credit have also theretofore been met with respect to such extension. No Letter of Credit shall have a term of more than one year; provided that a Letter of Credit may contain a provision pursuant to which it is deemed to be extended on an annual basis unless notice of termination is given by the Issuing Bank; provided further that no Letter of Credit shall have a term extending or be so extendible beyond the Letter of Credit Termination Date.

(c) Payments; Reimbursement Obligations. (i) Upon receipt from the beneficiary of any Letter of Credit of any notice of a drawing under such Letter of Credit, the Issuing Bank shall notify the Administrative Agent and the Administrative Agent shall promptly notify the Borrower and each other Revolving Lender as to the amount to be paid as a result of such demand or drawing and the payment date. The Borrower shall be irrevocably and unconditionally obligated forthwith to reimburse the Issuing Bank for any amounts paid by the Issuing Bank upon any drawing under any Letter of Credit, without presentment, demand, protest or other formalities of any kind.

(ii) All such amounts paid by the Issuing Bank and remaining unpaid by the Borrower (a “Reimbursement Obligation”) shall, if and to the extent that the amount of such Reimbursement Obligation would be permitted as a Borrowing pursuant to Section 3.02, and unless the Borrower otherwise instructs the Administrative Agent by not less than one Domestic Business Day’s prior notice, convert automatically to Revolving Base Rate Loans on the date such Reimbursement Obligation arises. The Administrative Agent shall, on behalf of the Borrower (which hereby irrevocably directs the Administrative Agent so to act on its behalf), give notice no later than 11:30 A.M. (New York City time) on such date requesting each Revolving Lender to make, and each Revolving Lender hereby agrees to make, a Revolving Base Rate Loan, in an amount equal to such Revolving Lender’s Revolving Credit Percentage of the Reimbursement Obligation with respect to which such notice relates. Each Revolving Lender shall make such Loan available to the Administrative Agent at its address specified in or pursuant to Section 9.01 in immediately available funds, not later than 1:00 P.M. (New York City time), on the date specified in such notice. The Administrative Agent shall pay the proceeds of such Revolving Loans to the Issuing Bank, which shall immediately apply such proceeds to repay the Reimbursement Obligation. All amounts not so repaid shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the rate applicable to Revolving Base Rate Loans for such day.

(iii) To the extent the Reimbursement Obligation is not refunded by a Revolving Lender pursuant to clause (ii) above, such Revolving Lender will pay to the Administrative Agent, for the account of the Issuing Bank, immediately upon the Issuing Bank’s demand at any time during the period commencing after such Reimbursement Obligation arises until reimbursement therefor in full by the Borrower, an amount equal to such Revolving Lender’s ratable share of such Reimbursement Obligation (in proportion to its participation therein), together with interest on such amount for each day from the date of the Issuing Bank’s demand for such payment (or, if such demand is made after 1:00 P.M. (New York City time) on such date, from the next succeeding Domestic Business Day) to the date of payment by such Lender of such amount at a rate of interest per annum equal to the Federal Funds Rate for the first three Domestic Business Days after the date of such demand and thereafter at a rate per annum equal to the Base Rate for each additional day. The Issuing Bank will pay to each Revolving Lender ratably all amounts received from the Borrower for application in payment of its Reimbursement Obligations in respect of any Letter of Credit, but only to the extent such Revolving Lender has made payment to the Issuing Bank in respect of such Letter of Credit pursuant hereto; provided that in the event such payment received by the Issuing Bank is required to be returned, such Revolving Lender will return to the Issuing Bank any portion thereof previously distributed to it by the Issuing Bank.

(d) Obligations Absolute. The obligations of the Borrower and each Revolving Lender under subsection (c) above shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement, under all circumstances whatsoever, including without limitation the following circumstances:

(i) any lack of validity or enforceability of this Agreement or any Letter of Credit or any document related hereto or thereto;

(ii) any amendment or waiver of or any consent to departure from all or any of the provisions of this Agreement or any Letter of Credit or any document related hereto or thereto;

(iii) the use which may be made of the Letter of Credit by, or any acts or omission of, a beneficiary of a Letter of Credit (or any Person for whom the beneficiary may be acting);

(iv) the existence of any claim, set-off, defense or other rights that the Borrower may have at any time against a beneficiary of a Letter of Credit (or any Person for whom the beneficiary may be acting), any Lender (including the Issuing Bank) or any other Person, whether in connection with this Agreement or the Letter of Credit or any document related hereto or thereto or any unrelated transaction;

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

(vi) any other act or omission to act or delay of any kind by any Lender (including the Issuing Bank), the Administrative Agent or any other Person or any other event or circumstance whatsoever that might, but for the provisions of this subsection (vi), constitute a legal or equitable discharge of or defense to the Borrower’s or the Lender’s obligations hereunder.

(e) Indemnification; Expenses. (i) Borrower hereby indemnifies and holds harmless each Revolving Lender (including each Issuing Bank) and the Administrative Agent from and against any and all claims, damages, losses, liabilities, costs or expenses which it may reasonably incur in connection with a Letter of Credit issued pursuant to this Section 2.16.

(ii) None of the Revolving Lenders (including an Issuing Bank) nor the Administrative Agent nor any of their officers or directors or employees or agents shall be liable or responsible, by reason of or in connection with the execution and delivery or transfer of or payment or failure to pay under any Letter of Credit, including without limitation any of the circumstances enumerated in subsection (d) above; provided that the Borrower shall not be required to indemnify any Lender, or the Administrative Agent, for any claims, damages, losses, liabilities, costs or expenses, to the extent found by a court of competent jurisdiction to have been caused by the gross negligence or willful misconduct of such Person; and provided further that, notwithstanding Section 2.16(d), the Borrower and each Lender shall have a claim for direct (but not consequential) damage suffered by it, to the extent found by a court of competent jurisdiction to have been caused by (x) the willful misconduct or gross negligence of the Issuing Bank in determining whether a request presented under any Letter of Credit complied with the terms of such Letter of Credit or (y) the Issuing Bank’s failure to pay under any Letter of Credit after the presentation to it of a request strictly complying with the terms and conditions of the Letter of Credit.

(iii) Nothing in this subsection (e) is intended to limit the obligations of the Borrower under any other provision of this Agreement. To the extent the Borrower does not indemnify an Issuing Bank as required by this subsection, the Revolving Lenders agree to do so ratably in accordance with their Revolving Commitments.

Section 2.17. Swing Loans. (a) Swing Loan Commitment. During the Swing Credit Period, so long as no Stop Issuance Notice is in effect, the Swing Loan Lender agrees, on the terms and conditions set forth in this Agreement, to make Swing Loans to the Borrower pursuant to this subsection from time to time in amounts such that at any time (i) the aggregate principal amount of Swing Loans outstanding at such time does not exceed the Swing Loan Commitment and (ii) the aggregate amount of Revolving Outstandings at such time does not exceed the aggregate amount of the Revolving Commitments at such time. Each Borrowing under this Section shall be in a principal amount of $1,000,000 or any larger multiple of $500,000 (except that any such Borrowing may be in the amount of the Swing Loan Commitment available in accordance with the immediately preceding sentence). Within the foregoing limits, the Borrower may borrow under this subsection, prepay Swing Loans and reborrow at any time during the Swing Credit Period under this subsection.

(b) Swing Loan Borrowing Procedure. The Borrower shall give the Swing Loan Lender notice (a “Notice of Swing Loan Borrowing”), not later than 12:00 Noon (New York City time) on the date of each Swing Loan Borrowing, specifying the amount and the date of such Borrowing, which shall be a Euro-Dollar Business Day. Not later than 2:00 P.M. (New York City time) on the date of each Swing Loan Borrowing, the Swing Loan Lender shall, unless it determines that any applicable condition specified in Article 3 has not been satisfied, make available the amount of such Swing Loan Borrowing, in Federal or other funds immediately available in New York City, to the Borrower at the Swing Loan Lender’s address specified in or pursuant to Section 9.01.

(c) Interest. Each Swing Loan shall bear interest on the outstanding principal amount thereof, for each day during each Interest Period applicable thereto, at a rate per annum equal to the sum of the Applicable Margin for Revolving Euro-Dollar Loans for such day plus the New York Interbank Offered Rate applicable to such Interest Period. Interest for each Interest Period shall be payable on the last day thereof. Any overdue principal of or interest on any Swing Loan shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the sum of the Applicable Margin for Revolving Base Rate Loans for such day plus the Base Rate for such day.

The “New York Interbank Offered Rate” applicable to any Interest Period means the rate per annum at which deposits in Dollars are offered to the Swing Loan Lender in the New York interbank market at approximately 12:00 Noon (New York City time) on the first day of such Interest Period in an amount approximately equal to the principal amount of the Swing Loan to which such Interest Period is to apply and for a period of time comparable to such Interest Period.

(d) Optional Prepayment. The Borrower may prepay the Swing Loans in whole at any time, or from time to time in part in a principal amount of at least

$1,000,000, by giving notice of such prepayment to the Swing Loan Lender not later than 1:00 P.M. (New York City time) on the date of prepayment and paying the principal amount to be prepaid, together with accrued interest thereon to the date of prepayment, to the Swing Loan Lender.

(e) Mandatory Prepayment. On the date of each Revolving Borrowing pursuant to Section 2.01, the Administrative Agent shall apply the proceeds thereof to prepay all Swing Loans then outstanding, together with interest accrued thereon to the date of prepayment.

(f) Payments. All payments to the Swing Loan Lender under this Section 2.17 shall be made to it at its address specified in or pursuant to Section 9.01, in Federal or other funds immediately available in New York City, not later than 2:00 P.M. (New York City time) on the date of payment.

(g) Refunding Unpaid Swing Loans. If (x) the Swing Loans are not paid in full on their Maturity Date, (y) the Swing Loans become immediately due and payable pursuant to Article 6, or (z) the Swing Loan Lender (in its discretion) elects to exercise its rights under this subsection (g), the Administrative Agent shall (if requested to do so by the Swing Loan Lender), by notice to the Revolving Lenders (including the Swing Loan Lender, in its capacity as a Revolving Lender), require each Revolving Lender to pay to the Administrative Agent for the account of the Swing Loan Lender an amount equal to such Revolving Lender’s Revolving Credit Percentage of the aggregate unpaid principal amount of the Swing Loans then outstanding. Such notice shall specify the date on which such payments are to be made, which shall be the first Domestic Business Day after such notice is given. Not later than 12:00 Noon (New York City time) on the date so specified, each Revolving Lender shall pay the amount so notified to it to the Administrative Agent at its address specified in or pursuant to Section 9.01, in Federal or other funds immediately available in New York City. Promptly upon receipt thereof, the Administrative Agent shall remit such amounts to the Swing Loan Lender. The amount so paid by each Revolving Lender shall constitute a Revolving Base Rate Loan to the Borrower and shall be applied by the Swing Loan Lender to repay the outstanding Swing Loans.

(h) Purchase of Participations in Swing Loans. If at the time Revolving Loans would have otherwise been made pursuant to Section 2.17(g), one of the events described in Section 6.01(h) or 6.01(i) with respect to the Borrower shall have occurred and be continuing or the Revolving Commitments shall have terminated, each Revolving Lender shall, on the date such Revolving Loans would have been made pursuant to the notice referred to in Section 2.17(g) (the “Refunding Date”), purchase an undivided participating interest in the relevant Swing Loan in an amount equal to such Revolving Lender’s Revolving Credit Percentage of the principal amount of such Swing Loan. On the Refunding Date, each Revolving Lender shall transfer to the Swing Loan Lender, in immediately available funds, such amount.

(i) Payments on Participated Swing Loans. Whenever, at any time after the Swing Loan Lender has received from any Revolving Lender such Revolving Lender’s payment pursuant to Section 2.17(h), the Swing Loan Lender receives any payment on account of the Swing Loan in which the Revolving Lenders have purchased participations pursuant to Section 2.17(h), the Swing Loan Lender will promptly distribute to each such Revolving Lender its ratable share of such payment (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Revolving Lender’s participating interest was outstanding and funded); provided that in the event that such payment received by the Swing Loan Lender is required to be returned, such Revolving Lender will return to the Swing Loan Lender any portion thereof previously distributed to it by the Swing Loan Lender.

(j) Obligations to Refund or Purchase Participations in Swing Loans Absolute. Each Revolving Lender’s obligation to transfer the amount of a Revolving Loan to the Swing Loan Lender as provided in Section 2.17(g) or to purchase a participating interest pursuant to Section 2.17(h) shall be absolute and unconditional and shall not be affected by any circumstance, including, without limitation, (i) any set-off, counterclaim, recoupment, defense or other right which such Revolving Lender, the Borrower or any other Person may have against the Swing Loan Lender or any other Person, (ii) the occurrence or continuance of a Default or an Event of Default or the termination or reduction of any Commitments, (iii) any adverse change in the condition (financial or otherwise) of the Borrower or any other Person, (iv) any breach of this Agreement by the Borrower, any other Lender or any other Person or (v) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing.

Section 2.18. Stop Issuance Notice. If the Required Banks determine at any time that the conditions set forth in Section 3.02 would not be satisfied in respect of a Revolving Borrowing at such time, then the Required Banks may request that the Administrative Agent issue a “Stop Issuance Notice”, and the Administrative Agent shall issue such notice to the Swing Loan Lender and to each Issuing Bank. Such Stop Issuance Notice shall be withdrawn upon a determination by the Required Banks that the circumstances giving rise thereto no longer exist. No Swing Loan shall be made and no Letter of Credit shall be issued while a Stop Issuance Notice is in effect. The Required Banks may request issuance of a Stop Issuance Notice only if there is a reasonable basis therefor, and shall consider reasonably and in good faith a request from the Borrower for withdrawal of the same on the basis that the conditions in Section 3.02 are satisfied; provided that the Administrative Agent, the Swing Loan Lender and the Issuing Banks may and shall conclusively rely on any Stop Issuance Notice while it remains in effect.

Except as reflected in the PBGC Settlement Agreement, no member of the ERISA Group has (i) sought a waiver of the minimum funding standard under Section 412 of the Internal Revenue Code in respect of any Plan, (ii) failed to make any contribution or payment to any Plan or Multiemployer Plan, or made any amendment to any Plan, which has resulted or could result in the imposition of a Lien or the posting of a bond or other security under ERISA or the Internal Revenue Code or (iii) incurred any liability under Title IV of ERISA other than a liability to the PBGC for premiums under Section 4007 of ERISA.

Section 4.07. Environmental Matters. In the ordinary course of its business, the Borrower conducts an ongoing review of the effect of Environmental Laws on the business, operations and properties of the Borrower and its Subsidiaries, in the course of which it identifies and evaluates associated liabilities and costs (including, without limitation, any capital or operating expenditures required for clean-up or closure of properties presently or previously owned, any capital or operating expenditures required to achieve or maintain compliance with environmental protection standards imposed by law or as a condition of any license, permit or contract, any related constraints on operating activities, including any periodic or permanent shutdown of any facility or reduction in the level of or change in the nature of operations conducted thereat, any costs or liabilities in connection with off-site disposal of wastes or Hazardous Substances and any actual or potential liabilities to third parties, including employees, and any related costs and expenses). On the basis of this review, the Borrower has reasonably concluded that such associated liabilities and costs, including the costs of complying with Environmental Laws, could not reasonably be expected to have a Material Adverse Effect.

Section 4.08. Taxes. The Borrower and its Subsidiaries (including, for purposes of this Section, the Borrower Joint Ventures) have filed all United States Federal income tax returns and all other material tax returns which are required to be filed by them and have paid or accrued all taxes shown to be due such returns or on any assessment received by the Borrower or any Subsidiary and required to be paid or accrued by it, except to the extent that any such taxes are being contested in good faith by appropriate proceedings.

Section 4.09. Subsidiaries. (a) Each of the Borrower’s Significant Subsidiaries (including, for purposes of this Section, the Borrower Joint Ventures) is duly organized, validly existing and, where applicable, in good standing under the laws of its jurisdiction of organization, and has the constitutive powers and all governmental licenses, authorizations, consents and approvals required to carry on its business as now conducted, except where the failure to have such licenses, consents, authorizations and approvals could not reasonably be expected to have a Material Adverse Effect. The Borrower has no Significant Subsidiaries which are not either Foreign Subsidiaries, JV Subsidiaries or, subject to Section 5.18(d)(v), Subsidiary Guarantors.

(b) Schedule 4.09 sets forth a correct list of each Subsidiary (including each Borrower Joint Venture) of the Borrower as of the Closing Date, separately identifying Significant Subsidiaries, Foreign Subsidiaries and JV Subsidiaries.

Section 4.10. No Regulatory Restrictions on Borrowing. No Obligor is (i) an “investment company” within the meaning of the Investment Company Act of 1940, as amended, or (ii) otherwise subject to any regulatory scheme (other than Regulation U) which restricts its ability to incur or guarantee debt.

Section 4.11. Full Disclosure. The financial and other information set forth in Borrower’s Form 10-K for the fiscal year ended December 31, 2005 and Form 10-Q for the fiscal quarter ended March 31, 2006 does not contain on the date hereof any material misstatement of fact or omit to state any material fact necessary to make the statements contained therein, in light of the circumstances under which they were made, not misleading; provided, however, to the extent any such information was based on or constituted a forecast or projection, the Borrower represents that it acted in good faith and utilized information available to it at the time such forecast or projection was prepared and assumptions believed by it to be reasonable in light of the then current and foreseeable business conditions of the Borrower and its Subsidiaries.

Section 5.03. Maintenance of Property; Insurance. (a) The Borrower will keep, and will cause each Subsidiary to keep, all property useful and necessary in its business in good working order and condition, ordinary wear and tear excepted, provided that no item of property need be so kept if the failure to keep it so individually or in the aggregate with all other items not so kept by the Borrower and its Subsidiaries could not reasonably be expected to have a Material Adverse Effect.

Section 5.19. Restrictions on Borrower Joint Ventures.

(ii) the Borrower and its Subsidiaries may create Asset Sale Liens on the Subject Assets;

(iii) any Liens arising under the Collateral Documents on the portion of the Subject Assets transferred to a Subject Assets Transferee or to an Acquiring Person will be released in accordance with the last sentence of Section 9.05(b); and

(iv) any Liens arising under the Collateral Documents on the Subject Assets not released in accordance with paragraph (iii) will be subordinate to any Asset Sale Lien on such Subject Assets.

(i) after giving effect to such Major Asset Sale, the Compliance Test and, in the case of an LCR Asset Sale, the LCR Compliance Test are met;

(ii) at the time of such Major Asset Sale and after giving effect thereto (on a pro forma basis for purposes of Section 5.11), no Default shall exist;

(iii) the sum of the gross cash proceeds received by the Borrower in respect of such Major Asset Sale plus the value of the interest of the Borrower in the Subject Assets Transferee (if any) after giving effect to such Major Asset Sale is not less than the value (as determined by the Board of Directors of the Borrower) of the portion of the Subject Assets transferred by the Borrower in connection with such Major Asset Sale;

(iv) the Borrower directly or indirectly is the operator of the Subject Assets in which it or a Subject Assets Transferee retains an interest; and

(c) No Subject Assets Transferee shall incur any Debt (other than (i) if such Subject Assets Transferee is a Subsidiary, Debt permitted to be incurred under Section 5.10(g) and (ii) if such Subject Assets Transferee is not a Subsidiary, Debt in an aggregate principal amount not to exceed (x) $50,000,000 less (y) the aggregate outstanding principal amount of Debt of Subsidiaries permitted solely by clause 5.10(g) at such time less (z) the aggregate outstanding principal amount of Debt secured by Liens permitted solely by clause 5.09(j) at such time).

(d) For purposes of this Section 5.20, the following terms have the following respective meanings:

“Acquiring Person” means a Person other than a Subject Assets Transferee which acquires (i) all or a portion of the Subject Assets or (ii) an interest in a Subject Assets Transferee in connection with a Major Asset Sale.

“Asset Sale Lien” means a Lien on the Subject Assets (including as a Lien for this purpose contractual rights with respect to the operation of the Subject Assets) arising in connection with a Major Asset Sale in favor of the Acquiring Person (or an affiliate thereof) which Lien does not secure any Debt.

“Major Asset Sale” means an Asset Sale designated by the Borrower by prior notice to the Administrative Agent as a Major Asset Sale, so long as in connection therewith (i) the conditions specified in subsection (b) are satisfied and (ii) the Borrower receives Net Cash Proceeds in an aggregate amount not less than $1,000,000,000 (which shall be deemed Net Cash Proceeds of such Major Asset Sale for purposes of any prepayment provisions set forth in a Term Loan Supplement). For this purpose (i) a transaction which produces substantially the same economic result as a sale of a partial interest in an asset, as might be achieved, for instance, through contractual arrangements allocating future revenues and costs attributable to the asset, shall be deemed an Asset Sale even though there may be no change in title to the asset or in the ownership of the Person which has title to the asset and (ii) a subsequent related transaction with the same Acquiring Person (or an Affiliate thereof) contemplated by the terms of the initial Major Asset Sale with such Person shall, for purposes of determining the applicability of and compliance with this Section, be deemed a single cumulative transaction.

“Subject Assets Transferee” means any Consolidated Subsidiary or Borrower Joint Venture which becomes the owner of the Subject Assets in connection with a Major Asset Sale.

(e) Nothing in this Section limits the ability of the Borrower and its Subsidiaries to sell assets (including Collateral) in compliance with Section 5.07 in transactions which do not constitute Major Asset Sales, and to obtain a release of Collateral pursuant to the last sentence of Section 9.05(b) in connection with any such sale.

ARTICLE 7

THE ADMINISTRATIVE AGENT

Section 7.01. Appointment and Authorization. Each Lender irrevocably appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under the Loan Documents as are delegated to the Administrative Agent by the terms hereof or thereof, together with all such powers as are reasonably incidental thereto.

Section 7.02. Administrative Agent and Affiliates. The financial institution serving as Administrative Agent shall have the same rights and powers under the Loan Documents as any other Lender and may exercise or refrain from exercising the same as though it were not the Administrative Agent, and such financial institution and its affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or affiliate of the Borrower as if it were not the Administrative Agent.

Section 7.03. Action by the Administrative Agent. The obligations of the Administrative Agent hereunder are only those expressly set forth herein. Without limiting the generality of the foregoing, the Administrative Agent shall not be required to take any action with respect to any Default, except, as expressly provided in Article 6.

Section 7.04. Consultation with Experts. The Administrative Agent may consult with legal counsel (who may be counsel for any Obligor), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts.

Section 7.05. Liability of Administrative Agent. None of the Administrative Agent, its affiliates, and the directors, officers, agents and employees of the Administrative Agent and its affiliates shall be liable for any action taken or not taken by it in connection herewith (i) with the consent or at the request of the Required Lenders (or such different number of Lenders as any provision hereof expressly requires for such consent or request) or (ii) in the absence of its own gross negligence or willful misconduct. None of the Administrative Agent, its affiliates, and the directors, officers, agents and employees of the Administrative Agent and its affiliates shall be responsible for or have any duty to ascertain, inquire into or verify (i) any statement, warranty or representation made in connection with this Agreement or any borrowing or issuance of a Letter of Credit hereunder; (ii) the performance or observance of any of the covenants or agreements of the Borrower; (iii) the satisfaction of any condition specified in Article 3, except receipt of items required to be delivered to the Administrative Agent; (iv) the validity, effectiveness or genuineness of any Loan Document or any other instrument or writing furnished in connection herewith or (v) the existence, validity or sufficiency of any Collateral. The Administrative Agent shall not incur any liability by acting in reliance upon any notice, consent, certificate, statement or other writing (which may be a bank wire, telex, facsimile or similar writing) believed by it to be genuine or to be signed by the proper party or parties. Without limiting the generality of the foregoing, the use of the term “agent” in this Agreement with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom and is intended to create or reflect only an administrative relationship between independent contracting parties.

Section 7.06. Indemnification. The Lenders shall, ratably in proportion to their Commitments, indemnify the Administrative Agent, its affiliates and the directors, officers, agents and employees of the Administrative Agent and its affiliates (to the extent not reimbursed by the Borrower) against any cost, expense (including counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from such indemnitees’ gross negligence or willful misconduct) that such indemnitees may suffer or incur in connection with this Agreement or any action taken or omitted by such indemnitees hereunder.

Section 7.07. Credit Decision. Each Lender acknowledges that it has, independently and without reliance on the Arranger, the Administrative Agent or any other Lender, and based on such documents and information as it has deemed

appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance on the Administrative Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking any action under this Agreement.

Section 7.08. Successor Administrative Agents. The Administrative Agent may resign at any time by giving notice thereof to the Lenders and the Borrower. Upon any such resignation, the Required Lenders shall have the right to appoint a successor for such resigning Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Required Lenders, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent gives notice of resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent, which shall be a commercial bank organized or licensed under the laws of the United States or of any State thereof and having a combined capital and surplus of at least $100,000,000. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. After any Administrative Agent’s resignation hereunder, the provisions of this Article shall inure to its benefit as to actions taken or omitted to be taken by it while it was an Administrative Agent.

Section 7.09. Administrative Agent’s Fees. The Borrower shall pay to the Administrative Agent for its own account fees in the amounts and at the times previously agreed upon in writing by the Borrower and the Administrative Agent.

ARTICLE 8

CHANGE IN CIRCUMSTANCES

Section 8.01. Basis for Determining Interest Rate Inadequate or Unfair. If on or before the first day of any Interest Period for any Euro-Dollar Loans of any Class:

(a) the Administrative Agent is advised by the Reference Lenders that deposits in dollars in the applicable amounts are not being offered to the Reference Lenders in the London interbank market for such Interest Period, or

(b) Lenders having at least 50% in aggregate amount of the Commitments of such Class (or, in the case of Term Lenders, holding at least 50% of the aggregate outstanding principal amount of the affected Class of Term Loans) advise the Administrative Agent that the London Interbank Offered Rate as determined by the Administrative Agent will not adequately and fairly reflect the cost to such Lenders of funding their Euro-Dollar Loans for such Interest Period,

the Administrative Agent shall forthwith give notice thereof to the Borrower and the Lenders, whereupon until the Administrative Agent notifies the Borrower that the circumstances giving rise to such suspension no longer exist, (i) the obligations of the Lenders to make Euro-Dollar Loans or to continue or convert outstanding Loans as or into Euro-Dollar Loans, as the case may be, shall be suspended and (ii) each outstanding Euro-Dollar Loan of the affected Class shall be converted into a Base Rate Loan on the last day of the then current Interest Period applicable thereto. Unless the Borrower notifies the Administrative Agent at least one Domestic Business Day before the date of any affected Borrowing for which a Notice of Borrowing has previously been given that it elects not to borrow on such date, such Borrowing shall instead be made as a Base Rate Borrowing.

Section 8.02. Illegality. If, after the date hereof, the adoption of any applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency (including without limitation the National Association of Insurance Commissioners (the “NAIC”)) charged with the interpretation or administration thereof, or compliance by any Lender (or its Euro-Dollar Lending Office) with any request or directive made or issued after the date hereof (whether or not having the force of law) of any such authority, central bank or comparable agency, shall make it unlawful or impossible for any Lender (or its Euro-Dollar Lending Office) to make, maintain or fund its Euro-Dollar Loans and such Lender shall so notify the Administrative Agent, the Administrative Agent shall forthwith give notice thereof to the other Lenders and the Borrower, whereupon until such Lender notifies the Borrower and the Administrative Agent that the circumstances giving rise to such suspension no longer exist, the obligation of such Lender to make Euro-Dollar Loans, or to convert outstanding Loans into Euro-Dollar Loans or continue outstanding Loans as Euro-Dollar Loans, shall be suspended. Before giving any notice to the Administrative Agent pursuant to this Section, such Lender shall designate a different Euro-Dollar Lending Office if such designation will avoid the need for giving such notice and will not, in the judgment of such Lender, be otherwise disadvantageous to such Lender. If such notice is given, each Euro-Dollar Loan of such Lender then outstanding shall be converted to a Base Rate Loan either (i) on the last day of the then current Interest Period applicable to such Euro-Dollar Loan if such Lender may lawfully continue to maintain and

fund such Loan as a Euro-Dollar Loan to such day or (ii) immediately if such Lender shall determine that it may not lawfully continue to maintain and fund such Loan as a Euro-Dollar Loan to such day. Interest and principal on any such Base Rate Loan shall be payable on the same dates as, and on a pro rata basis with, the interest and principal payable on the related Euro-Dollar Loans of the other Lenders.

Section 8.03. Increased Cost and Reduced Return. (a) If after the date hereof, the adoption of any applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency (including without limitation the NAIC) charged with the interpretation or administration thereof, or compliance by any Lender (or its Applicable Lending Office) with any request or directive made or issued after the date hereof (whether or not having the force of law) of any such authority, central bank or comparable agency, shall impose, modify or deem applicable any reserve (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System, but excluding any such requirement with respect to which such Lender is entitled to compensation during the relevant Interest Period under Section 2.15), special deposit, insurance assessment or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (or its Applicable Lending Office) or shall impose on any Lender (or its Applicable Lending Office) or on the London interbank market any other condition affecting its Fixed Rate Loans, its Notes or its obligation to make Fixed Rate Loans or its obligations hereunder in respect of Letters of Credit and the result of any of the foregoing is to increase the cost to such Lender (or its Applicable Lending Office) of making or maintaining any Fixed Rate Loan, or of issuing or participating in any Letter of Credit, or to reduce the amount of any sum received or receivable by such Lender (or its Applicable Lending Office) under this Agreement or under its Note with respect thereto, by an amount deemed by such Lender to be material, then, within 15 days after demand by such Lender (with a copy to the Administrative Agent), the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such increased cost or reduction.

(b) If any Lender shall have determined that, after the date hereof, the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change in any such law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency (including without limitation the NAIC), which adoption, change, request or directive was effected after the date hereof, has or would have the effect of reducing the rate of return on capital of such Lender (or its Parent) as a consequence of such Lender’s

obligations hereunder to a level below that which such Lender (or its Parent) could have achieved but for such adoption, change, request or directive (taking into consideration its policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, within 15 days after demand by such Lender (with a copy to the Administrative Agent), the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender (or its Parent) for such reduction.

(c) Each Lender will promptly notify the Borrower and the Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Lender to compensation pursuant to this Section and will designate a different Applicable Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Lender, be otherwise disadvantageous to it. A certificate of any Lender claiming compensation under this Section and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error. In determining such amount, such Lender may use any reasonable averaging and attribution methods.

Section 8.04. Taxes. (a) For the purposes of this Section, the following terms have the following meanings:

“Taxes” means any and all present or future taxes, duties, levies, imposts, deductions, charges or withholdings with respect to any payment by the Borrower pursuant to this Agreement or under any Note, and all liabilities with respect thereto, excluding (the “Excluded Taxes”) (i) in the case of each Lender Party, taxes imposed on its net income, and franchise, capital or similar taxes (including branch profits taxes) imposed on it, by a jurisdiction under the laws of which (or of a political subdivision of which) it is organized or in which its principal executive office is located or in which its Applicable Lending Office is located and (ii) in the case of each Lender, any United States withholding tax imposed on such payment, but not excluding any portion of such tax that exceeds the United States withholding tax which would have been imposed on such a payment to such Lender under the laws and treaties in effect when such Lender first becomes a party to this Agreement if that Lender is in compliance with its obligations under Section 8.04(d).

“Other Taxes” means any present or future stamp or documentary taxes and any other excise or property taxes, or similar charges or levies, which arise from any payment made pursuant to this Agreement or under any Note or from the execution, delivery, registration or enforcement of, or otherwise with respect to, any Loan Document other than Taxes and Excluded Taxes.

(b) All payments by the Borrower to or for the account of any Lender Party hereunder or under any Note shall be made without deduction for any Taxes or Other Taxes; provided that, if the Borrower shall be required by law to deduct

any Taxes or Other Taxes from any such payment, (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) such Lender Party receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law and (iv) the Borrower shall promptly furnish to the Administrative Agent, at its address specified in or pursuant to Section 9.01, the original or a certified copy of a receipt evidencing payment thereof.

(c) The Borrower agrees to indemnify each Lender Party for the full amount of Taxes and Other Taxes (including, without limitation, any Taxes or Other Taxes imposed or asserted (whether or not correctly) by any jurisdiction on amounts payable under this Section) paid by such Lender Party and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. This indemnification shall be paid within 15 days after such Lender Party makes demand therefor.

(d) Each Lender Party organized under the laws of a jurisdiction outside the United States, (i) before it signs and delivers this Agreement in the case of each Lender Party listed on the signature pages hereof and before it becomes a Lender Party in the case of each other Lender Party, (ii) before it changes the country where its Applicable Lending Office is located, (iii) from time to time thereafter if requested in writing by the Borrower (but only so long as such Lender Party remains lawfully able to do so), and (iv) at the time or times prescribed by applicable law, shall provide each of the Borrower and the Administrative Agent with (x) Internal Revenue Service form W-8 ECI or W-8 BEN, as appropriate, or any successor form prescribed by the Internal Revenue Service, certifying that such Lender Party is entitled to benefits under an income tax treaty to which the United States is a party which exempts such Lender Party from United States withholding tax or reduces the rate of withholding tax on payments of interest for the account of such Lender Party or certifying that the income receivable by it pursuant to this Agreement is effectively connected with the conduct of a trade or business in the United States or (y) solely if such Lender is claiming exemption from United States withholding tax under Section 871(h) or 881(c) of the Internal Revenue Code with respect to payments of “portfolio interest”, a Form W-8, or any successor form prescribed by the Internal Revenue Service, and a certificate representing that such Lender is not a bank for purposes of Section 881(c) of the Internal Revenue Code, is not a 10-percent shareholder (within the meaning of Section 871(h)(3)(B) of the Internal Revenue Code) of the Borrower and is not a controlled foreign corporation related to the Borrower (within the meaning of Section 864(d)(4) of the Internal Revenue Code).

(e) For any period with respect to which a Lender Party has failed to provide the Borrower or the Administrative Agent with the appropriate form

referred to in Section 8.04(d) (unless such failure is due to a change in treaty, law or regulation occurring after the date on which such form originally was required to be provided), such Lender Party shall not be entitled to indemnification under Section 8.04(b) or 8.04(c) with respect to Taxes imposed by the United States; provided that if a Lender Party, that is otherwise exempt from or subject to a reduced rate of withholding tax, becomes subject to Taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps as such Lender Party shall reasonably request to assist such Lender Party to recover such Taxes.

(f) If the Borrower is required to pay additional amounts to or for the account of any Lender pursuant to this Section as a result of a change in law or treaty occurring after such Lender first became a party to this Agreement, then such Lender will, at the Borrower’s request, change the jurisdiction of its Applicable Lending Office if, in the judgment of such Lender, such change (i) will eliminate or reduce any such additional payment which may thereafter accrue and (ii) is not otherwise disadvantageous to such Lender.

Section 8.05. Base Rate Loans Substituted for Affected Euro-Dollar Loans. If (i) the obligation of any Lender to make, or to continue or convert outstanding Loans as or to, Euro-Dollar Loans has been suspended pursuant to Section 8.02 or (ii) any Lender has demanded compensation under Section 8.03 or 8.04 with respect to its Euro-Dollar Loans, and in any such case the Borrower shall, by at least five Euro-Dollar Business Days’ prior notice to such Lender through the Administrative Agent, have elected that the provisions of this Section shall apply to such Lender, then, unless and until such Lender notifies the Borrower that the circumstances giving rise to such suspension or demand for compensation no longer exist, all Loans which would otherwise be made by such Lender as (or continued as or converted to) Euro-Dollar Loans shall instead be Base Rate Loans on which interest and principal shall be payable contemporaneously with the related Euro-Dollar Loans of the other Lenders. If such Lender notifies the Borrower that the circumstances giving rise to such suspension or demand for compensation no longer exist, the principal amount of each such Base Rate Loan shall be converted into a Euro-Dollar Loan on the first day of the next succeeding Interest Period applicable to the related Euro-Dollar Loans of the other Lenders.

Section 8.06. Substitution of Bank. If (i) the obligation of any Lender to make or to convert or continue outstanding Loans as or into Euro-Dollar Loans has been suspended pursuant to Section 8.02, (ii) any Lender has demanded compensation under Section 8.03 or 8.04 or (iii) any Lender fails to execute and deliver any consent, amendment or waiver to this Agreement requested by the Borrower by the date specified by the Borrower (or gives the Borrower written notice prior to such date of its intention not to do so), the Borrower shall have the right to designate a substitute bank or banks (which may be one or more of the Lenders) reasonably mutually satisfactory to the Borrower and the Administrative

Agent (and, in the case of a Revolving Lender, the Issuing Banks) to purchase for cash, pursuant to an Assignment and Assumption Agreement in substantially the form of Exhibit D hereto, the outstanding Loans and Letter of Credit Liabilities of such Lender and assume the Commitment(s) of such Lender, without recourse to or warranty by, or expense to, such Lender, for a purchase price equal to the principal amount of all of such Lender’s outstanding Loans and Reimbursement Obligations plus any accrued but unpaid interest thereon and the accrued but unpaid fees for the account of such Lender hereunder plus such amount, if any, as would be payable pursuant to Section 2.11 if the outstanding Loans of such Lender were prepaid in their entirety on the date of consummation of such assignment.

Each such notice, request or other communication shall be effective if given by facsimile, when transmitted to the facsimile number referred to in this Section and confirmation of receipt is received, or if given by any other means, when delivered at the address referred to in this Section; provided that notices to the Administrative Agent under Article 2 or Article 8 shall not be effective until received.

The Administrative Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it; provided that approval of such procedures may be limited to particular notices or communications.

(c) Notices by the Borrower pursuant to Article 2 shall be irrevocable; provided that, if a notice of optional or mandatory prepayment or termination or reduction of Commitments pursuant to Section 2.04, 2.08 or 2.09 is expressed to be contingent upon the consummation of an event or transaction, such notice may

be revoked by the Borrower, or the effective date thereof may be postponed by a period of up to 30 days, in the event such event or transaction is delayed or cancelled; provided further that in any such event (i) the Borrower shall give the applicable Lenders through the Administrative Agent not less than three Euro-Dollar Business Days’ notice of the ultimate effective date of any such notice and (ii) any such revocation or postponement of the effective date of a notice shall be subject to the rights of the Lenders under Section 2.11.

Section 9.02. No Waivers. No failure or delay by any Lender Party exercising any right, power or privilege hereunder or under any Note shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.

Section 9.03. Expenses; Indemnification. (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses of the Administrative Agent, including reasonable fees and disbursements of special counsel for the Administrative Agent, in connection with the preparation of the Loan Documents, any waiver or consent thereunder or any amendment thereof or any Default thereunder and (ii) if an Event of Default occurs, all out-of-pocket expenses incurred by each Lender Party, including the fees and disbursements of counsel, in connection with such Event of Default and collection, bankruptcy, insolvency and other enforcement proceedings resulting therefrom.

(b) The Borrower agrees to indemnify each Lender Party, their respective affiliates and the respective directors, officers, agents and employees of the foregoing (each an “Indemnitee”) and hold each Indemnitee harmless from and against any and all liabilities, losses, damages, costs and expenses of any kind (including without limitation reasonable expenses of investigation by engineers, environmental consultants and similar technical personnel), including, without limitation, the reasonable fees and disbursements of counsel, which may be incurred by such Indemnitee in connection with any investigative, administrative or judicial proceeding (whether or not such Indemnitee shall be designated a party thereto) brought or threatened relating to or arising out of any Loan Document or any actual or proposed use of any Commitments or any proceeds of Loans hereunder; provided that no Indemnitee shall have the right to be indemnified hereunder for (i) such Indemnitee’s own gross negligence or willful misconduct or (ii) liabilities, losses, damages, costs and expenses arising out of a proceeding in which such Indemnitee and the Borrower are adverse parties and in which the Borrower prevails on the merits, in each case as determined by a court of competent jurisdiction.

Section 9.04. Set-Offs. (a) If (i) an Event of Default has occurred and is continuing and Lenders holding more than 50% in aggregate unpaid principal amount of the Loans have requested the Administrative Agent to declare the

Loans to be immediately due and payable pursuant to Section 6.01, or (ii) the Loans have become immediately due and payable without notice as provided in Section 6.01, then each Lender is hereby authorized by the Borrower at any time and from time to time, to the extent permitted by applicable law, without notice to the Borrower (any such notice being expressly waived by the Borrower), to set off and apply all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender to or for the account of the Borrower against any obligations of the Borrower to such Lender now or hereafter existing under this Agreement, regardless of whether any such deposit or other obligation is then due and payable or is in the same currency or is booked or otherwise payable at the same office as the obligation against which it is set off and regardless of whether such Lender shall have made any demand for payment under this Agreement. Each Lender agrees promptly to notify the Borrower after any such set-off and application made by such Lender; provided that any failure to give such notice shall not affect the validity of such setoff and application. The rights of the Lenders under this subsection are in addition to any other rights and remedies which the Lenders may have.

(b) Each Lender agrees that if it shall, by exercising any right of set-off or counterclaim or otherwise, receive payment of a proportion of the aggregate amount of principal and interest then due with respect to the Loans and Letter of Credit Liabilities held by it which is greater than the proportion received by any other Lender in respect of the aggregate amount of principal and interest then due with respect to the Loans and Letter of Credit Liabilities held by such other Lender, the Lender receiving such proportionately greater payment shall purchase such participations in the Loans held by the other Lenders, and such other adjustments shall be made, as may be required so that all such payments of principal and interest with respect to the Loans and Letter of Credit Liabilities held by the Lenders shall be shared by the Lenders pro rata; provided that nothing in this Section shall impair the right of any Lender to exercise any right of set-off or counterclaim it may have and to apply the amount subject to such exercise to the payment of indebtedness of the Borrower other than its indebtedness in respect of the Loans; and provided further that this Section shall not require sharing by the Swing Loan Lender of amounts received in respect of Swing Loans pursuant to Section 2.17.

Section 9.05. Amendments and Waivers. (a) Any provision of this Agreement or the Notes may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by the Borrower and the Required Lenders (and, if the rights or duties of the Administrative Agent, any Issuing Bank or the Swing Loan Lender (in such capacities) are affected thereby, by it); provided that no such amendment or waiver shall:

(i) unless signed by each Lender affected thereby, (A) increase the Commitment of any Lender, (B) reduce the principal of or rate of interest on any Loan or the amount to be reimbursed in respect of any

Letter of Credit or any interest thereon or any fees with respect thereto, or (C) postpone the Maturity Date for any Loan or the date fixed for any scheduled payment of any principal of or interest on any Loan or for reimbursement in respect of any Letter of Credit or any interest thereon or fees with respect thereto or any fees payable with respect to the Revolving Commitments or for the termination of any Revolving Commitment, or (D) postpone the expiry date of any Letter of Credit to a date that is later than the Revolving Credit Termination Date,

(ii) unless signed by all the Lenders, change the percentage set forth in the definition of Required Lenders or this Section 9.05; or

(iii) unless signed by Revolving Lenders holding, in the aggregate, Revolving Credit Percentages of greater than 50%, waive any condition to any Borrowing of Revolving Loan or issuance of Letter of Credit.

(b) Any provision of the Collateral Documents or the Subsidiary Guarantee may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by each Obligor party thereto and the Administrative Agent with the consent of the Required Lenders; provided that no such amendment or waiver shall, unless signed by all the Lenders, effect or permit a release of all or substantially all of the Collateral, release all or substantially all of the value of the Subsidiary Guarantee or permit termination of the Subsidiary Guarantee as to all or substantially all of the Subsidiary Guarantors. Notwithstanding the foregoing, (i) the Subsidiary Guarantee shall be terminated as to one or more Subsidiary Guarantors and Collateral (but not the proceeds thereof) shall be released from the Lien of the Collateral Documents from time to time as necessary to effect any sale of assets, including the sale of a Subsidiary Guarantor, permitted by the Loan Documents, (ii) the Subsidiary Guarantee shall be terminated as to any Subsidiary Guarantor which shall have become a Subsidiary Guarantor solely by reason of Section 5.18(d)(i)(B) at such time as such Subsidiary Guarantor shall have disposed of, pursuant to a transaction permitted under the Loan Documents, all Collateral the ownership of which caused it to become a Subsidiary Guarantor and (iii) the Administrative Agent shall execute and deliver all release documents reasonably requested to evidence such release.

(c) Each Lender party hereto consents to the execution and delivery by the Administrative Agent of such amendments to the Collateral Documents as shall be necessary or desirable in order to permit any Senior Notes to be secured by the Collateral as contemplated by Section 5.09(g).

Section 9.06. Successors; Participations and Assignments. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, except that the Borrower may not assign or otherwise transfer any of its rights under this Agreement without the prior written consent of all the Lender Parties.

(b) Any Lender may at any time grant to one or more banks, institutions or other entities that regularly make, purchase or invest in bank loans (each a “Participant”) participating interests in its Commitments or any or all of its Loans and Letter of Credit Liabilities. If a Lender grants any such participating interest to a Participant, whether or not upon notice to the Borrower and the Administrative Agent, such Lender shall remain responsible for the performance of its obligations hereunder, and the Borrower and the Administrative Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement pursuant to which any Lender may grant such a participating interest shall provide that such Lender shall retain the sole right and responsibility to enforce the obligations of the Borrower hereunder including, without limitation, the right to approve any amendment, modification or waiver of any provision of this Agreement; provided that such participation agreement may provide that such Lender will not agree to any modification, amendment or waiver of this Agreement described in clauses (A) through (C) of Section 9.05(a)(i) without the consent of the Participant. The Borrower agrees that, subject to Section 9.06(e), each Participant shall, to the extent provided in its participation agreement, be entitled to the benefits of Section 2.15 and Article 8 with respect to its participating interest. An assignment or other transfer which is not permitted by Section 9.06(c) below shall be given effect for purposes of this Agreement only to the extent of a participating interest granted in accordance with this subsection.

(c) Any Lender may at any time assign to one or more banks, other institutions or other entities that regularly make, purchase or invest in bank loans (each an “Assignee”) all, or a proportionate part of all, of its Commitment of any Class or its Loans and Letter of Credit Liabilities of any Class and such Assignee shall assume such rights and obligations, pursuant to an Assignment and Assumption Agreement substantially in the form of Exhibit D hereto signed by such Assignee and such transferor Lender, with (and subject to) the subscribed consent of the Borrower (which shall not be unreasonably withheld or unreasonably delayed) and the Administrative Agent (and, in the case of a Revolving Commitment, the Issuing Banks); provided that (i) after giving effect to any proposed assignment, unless each of the Borrower and the Administrative Agent otherwise consent, (A) the Credit Exposure of a transferor Lender (or in the case of a transferor Lender that is a fund, the aggregate Credit Exposure of such Lender and its Related Funds) shall be equal to $0 or at least $5,000,000 if the transferor is a Revolving Lender, and (B) the amount of the Credit Exposure of a transferor Lender subject to such assignment shall be at least equal to (x) $5,000,000 if the Assignee is a Revolving Lender or (y) $1,000,000 if the Assignee is a Term Lender, unless in either case the proposed Assignee is an affiliate of such transferor Lender, an Approved Fund or was a Lender

immediately before such assignment, (ii) if an Event of Default shall have occurred and be continuing, no such consent of the Borrower shall be required and (iii) no consent of the Borrower or the Administrative Agent shall be required for an assignment of any Term Loan to a Lender, an Affiliate of a Lender or an Approved Fund. When such instrument has been signed and delivered by the parties thereto and recorded as provided in Section 2.14, and such Assignee has paid to such transferor Lender the purchase price agreed between them, such Assignee shall be a Lender party to this Agreement and shall have all the rights and obligations of a Lender with a Commitment and/or Loans as set forth in such instrument of assumption, and the transferor Lender shall be released from its obligations hereunder to a corresponding extent, and no further consent or action by any party shall be required. Upon the consummation of any assignment pursuant to this subsection, the transferor Lender, the Administrative Agent and the Borrower shall make appropriate arrangements so that, if required, a new Note is issued to the Assignee. In connection with any such assignment (other than an assignment to which the Administrative Agent or any affiliate of the Administrative Agent is a party), the transferor Lender shall pay to the Administrative Agent an administrative fee for processing such assignment in the amount of $3,500. If the Assignee is not incorporated under the laws of the United States or a State thereof, it shall deliver to the Borrower and the Administrative Agent certification as to exemption from deduction or withholding of taxes in accordance with Section 8.04(d). The Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire in which the Assignee designates one or more credit contacts to whom all syndicate-level information (which may contain material non-public information about the Borrower, its Subsidiaries and Affiliates or their respective securities) will be made available and who may receive such information in accordance with the assignee’s compliance procedures and applicable laws, including Federal and state securities laws.

(d) Any Lender 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 Lender, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(e) No Assignee, Participant or other transferee of any Lender’s rights shall be entitled to receive any greater payment under Section 8.03 or 8.04 than such Lender would have been entitled to receive with respect to the rights transferred, unless such transfer is made with the Borrower’s prior written consent or by reason of the provisions of Section 8.02, 8.03 or 8.04 requiring such Lender to designate a different Applicable Lending Office under certain circumstances.

Section 9.07. Designated Lenders. (a) Subject to the provisions of this Section 9.07(a), any Lender may from time to time elect to designate an Eligible Designee to provide all or a portion of the Loans to be made by such Lender pursuant to this Agreement; provided that such designation shall not be effective unless the Borrower and the Administrative Agent consent thereto. When a Lender and its Eligible Designee shall have signed a designation agreement substantially in the form of Exhibit E hereto and the Borrower and the Administrative Agent shall have signed their respective consents thereto, such Eligible Designee shall become a Designated Lender for purposes of this Agreement. The Designating Lender shall thereafter have the right to permit such Designated Lender to provide all or a portion of the loans to be made by such Designating Lender pursuant to Section 2.01 and the making of such Loans or portions thereof shall satisfy the obligation of the Designating Lender to the same extent, and as if, such Loans or portion thereof were made by the Designating Lender. As to any Loans or portion thereof made by it, each Designated Lender shall have all the rights that a Lender making such Loans or portion thereof would have had under this Agreement and otherwise; provided that (x) its voting rights under this Agreement shall be exercised solely by its Designating Lender and (y) its Designating Lender shall remain solely responsible to the other parties hereto for the performance of its obligations under this Agreement, including its obligations in respect of the Loans or portion thereof made by it. No additional Note shall be required to evidence Loans or portions thereof made by a Designated Lender; and the Designating Lender shall be deemed to hold its Note as agent for its Designated Lender to the extent of the Loans or portion thereof funded by such Designated Lender. Each Designating Lender shall act as Administrative Agent for its Designated Lender and give and receive notices and other communications on its behalf. Any payments for the account of any Designated Lender shall be paid to its Designating Lender as Administrative Agent for such Designated Lender and neither the Borrower nor the Administrative Agent shall be responsible for any Designating Lender’s application of such payments. In addition, any Designated Lender may (i) with notice to, but without the prior written consent of, the Borrower or the Administrative Agent, assign all or portions of its interest in any Loans to its Designating Lender or to any financial institutions consented to by the Borrower and the Administrative Agent providing liquidity and/or credit facilities to or for the account of such Designated Lender to support the funding of Loans or portions thereof made by such Designated Lender and (ii) disclose on a confidential basis any non-public information relating to its Loans or portions thereof to any rating agency, commercial paper dealer or provider of any guarantee, surety, credit or liquidity enhancement to such Designated Lender.

(b) Each party to this Agreement agrees that it will not institute against, or join any other Person in instituting against, any Designated Lender any bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding or other proceeding under any federal or state bankruptcy or similar law, for one

year and a day after all outstanding senior indebtedness of such Designated Lender is paid in full. The Designating Lender for each Designated Lender agrees to indemnify, save, and hold harmless each other party hereto for any loss, cost, damage and expense arising out of its inability to institute any such proceeding against such Designated Lender. This Section 9.07(b) shall survive the termination of this Agreement.

Section 9.08. No Reliance on Margin Stock. Each of the Lenders represents to the Administrative Agent and each of the other Lenders that it in good faith is not relying upon any Margin Stock as collateral in the extension or maintenance of the credit provided for in this Agreement.

Section 9.09. Governing Law; Submission to Jurisdiction. This Agreement and each Note shall be governed by, and construed and interpreted in accordance with, the laws of the State of New York. To the extent permitted by applicable law, the Borrower hereby submits to the nonexclusive jurisdiction of the United States District Court for the Southern District of New York and of any New York State court sitting in New York City for purposes of all legal proceedings arising out of or relating to this Agreement or the transactions contemplated hereby. The Borrower irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of the venue of any such proceeding brought in such a court and any claim that any such proceeding brought in such a court has been brought in an inconvenient forum.

Section 9.10. Counterparts; Effectiveness. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective on the date that the Administrative Agent shall have received counterparts hereof signed by each of the parties hereto (or, in the case of any party as to which an executed counterpart shall not have been received, receipt by the Administrative Agent in the form satisfactory to it of facsimile or other written confirmation from such party of execution of a counterpart hereof by such party).

Section 9.11. WAIVER OF JURY TRIAL. TO THE EXTENT PERMITTED BY APPLICABLE LAW, EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

(iii) (A) the funds to be used by it for any Loan or Letter of Credit Liability or interest therein which constitutes, under the Internal Revenue Code or ERISA, the assets of any ERISA Plan are invested in an investment fund which is managed by a “Qualified Professional Asset Manager” as such term is defined in Prohibited Transaction Class Exemption 84-14 issued by the U.S. Department of Labor, and (B) such Loan or Letter of Credit Liability or interest therein is and the subsequent holding of the Note or any agreement related thereto shall at all times thereafter be, exempt under Prohibited Transaction Class Exemption 84-14 to the fullest extent provided therein;

(iv) the assets to be used by it constitute the assets of an investment company registered under the Investment Company Act of 1940; or

(b) Representations of Transferees. Each Person that becomes an Assignee or Participant hereunder shall be deemed to make, effective upon the acceptance of any assignment of an interest hereunder or the entering into of any participation agreement contemplated in Section 9.06(b), the representations and warranties set forth in Section 9.12(a). Such deemed representation shall be

effective against, and binding on, such Assignee or Participant to the same extent as if such Assignee or Participant had executed an original counterpart of this Agreement.

(c) Additional ERISA Representations.
