Upon receipt of any such notice the Administrative Agent shall promptly notify each Lender thereof.

(b) Any Eurodollar Loan may be continued as such upon the expiration of the then current Interest Period with respect thereto by the Borrower giving irrevocable notice to the Administrative Agent, in accordance with the applicable provisions of the term “Interest Period” set forth in Section 1.1, of the length of the next Interest Period to be applicable to such Loans, provided that no Eurodollar Loan hereunder may be continued as such when any Default or Event of Default has occurred and is continuing and the Administrative Agent has or the Required Lenders have determined in its or their sole discretion not to permit such continuations, and provided, further, that if the Borrower shall fail to give any required notice as described above in this paragraph or if such continuation is not permitted pursuant to the preceding proviso such Loans shall be automatically converted to Base Rate Loans on the last day of such then expiring Interest Period. Upon receipt of any such notice the Administrative Agent shall promptly notify each Lender thereof.

2.7. Inability to Determine Interest Rate. If prior to the first day of any Interest Period:

(a) the Administrative Agent shall have reasonably determined (which determination shall be conclusive and binding upon the Borrower) that, by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period, or

(b) the Administrative Agent shall have received notice from the Required Lenders that the Eurodollar Rate determined or to be determined for such Interest Period in good faith by such Required Lenders will not adequately and fairly reflect the cost to such Lenders (as conclusively certified by such Lenders) of making or maintaining their affected Loans during such Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the Borrower and the relevant Lenders as soon as practicable thereafter. If such notice is given, any Loans hereunder that were to have been converted on the first day of such Interest Period to Eurodollar Loans shall be continued as Base Rate Loans and (z) any outstanding Eurodollar Loans hereunder shall be converted, on the last day of the then-current Interest Period, to Base Rate Loans; provided that if the circumstances giving rise to such notice shall cease or otherwise become inapplicable to such Required Lenders, then such Required Lenders shall promptly give notice of such change in circumstances to the Administrative Agent and the Borrower. Until such notice has been withdrawn by the Administrative Agent, no further Eurodollar Loans hereunder shall be made or continued as such, nor shall the Borrower have the right to convert Loans hereunder to Eurodollar Loans.

In the event that Terra or any of its Subsidiaries (i) request that the Required Lenders consent to an amendment to Section 6.24(c) hereof to increase the amount of Debt permitted to be incurred by PLNL thereunder, (ii) such request is a bona fide, good faith proposal and the board of PLNL has authorized the making thereof; and (iii) the Required Lenders fail to consent to such request within 30 days of written request therefor, the Borrower may within 90 days of such failure to consent, prepay the Term Loans in whole in accordance with this Section 2.8 provided that the applicable prepayment premium with respect to such prepayment will be 50% of the prepayment premium that would otherwise have been payable.

2.9. Mandatory Prepayment. (a) In the event of any Asset Sale or casualty or condemnation of any Property of the Borrower or any of its Subsidiaries (including the Trinidad Interests or any part thereof) occurring prior to the Termination Date that results in Net Cash Proceeds in excess of $1,000,000 in the aggregate, or any prepayment required pursuant to Section 6.24, (x) the Borrower shall promptly notify the Administrative Agent of such proposed Asset Sale or such casualty or condemnation or receipt of proceeds of such Asset Sale, casualty or condemnation (including the amount of the estimated Net Cash Proceeds to be received by the Borrower or such Subsidiary in respect thereof) and (y) promptly upon receipt by the Borrower or such Subsidiary of the Net Cash Proceeds of such Asset Sale, casualty or condemnation, the Borrower shall deliver all of such Net Cash Proceeds in excess of $1,000,000 in the aggregate to the Administrative Agent for application to the then outstanding Loans and prepayment premium as set forth in Section 2.9(b) below. Nothing herein contained shall impair or otherwise affect the prohibitions against the disposition of Property or Asset Sales contained herein and in the Loan Documents. Any proceeds of an Asset Sale, casualty or condemnation in this Section 2.9(a) designated to pay actual taxes payable and costs of such Asset Sale, casualty or condemnation shall be held by the Administrative Agent in escrow until applied to such taxes and costs.

(b) Amounts to be applied in connection with prepayments made pursuant to paragraph (a) of this Section 2.9 shall be applied, pro rata such that if any mandatory prepayment notice is given or payment received: (i) at any time prior to the second anniversary of the Extension Date, an amount equal to 104.4% of the principal amount together with accrued and unpaid interest of the respective Term Loans shall be payable on the date specified therein or upon which payment is received; (ii) at any time after the second anniversary of the Extension Date but prior to the third anniversary of the Extension Date, 103.2% of the principal amount together with accrued and unpaid interest of the respective Term Loans shall be payable on the date specified therein or upon which payment is received; and (iii) at any time after the third anniversary of the Extension Date and prior to the Termination Date, 102.4% of the principal amount together with accrued and unpaid interest of the respective Term Loans shall be payable on the date specified therein or upon which payment is received, provided that, with respect to the first $25,000,000 of the Loans (in the aggregate and less any amounts prepaid at 101% of the principal amount

pursuant to the first proviso to Section 2.8) required at any time prior to the first anniversary of the Extension Date to be repaid pursuant to paragraph (a) of this Section 2.9, when a mandatory prepayment notice is given or payment received in respect thereof, an amount equal to 101% of the principal amount together with accrued and unpaid interest of the respective Term Loans shall be payable on the date specified therein or upon which payment is received.

2.10. Pro Rata Treatment, Etc. (a) Each borrowing by the Borrower from the Lenders hereunder, all payments and prepayments of principal and interest in respect of the Loans (except as provided in Section 2.14) and all payments of Fees (unless otherwise specified) shall be made pro rata among the Lenders in accordance with their respective Term Loan Percentages.

(b) All payments (including prepayments) by the Borrower hereunder and under the Notes (whether on account of principal, interest, fees or otherwise) shall be made without set off or counterclaim in Dollars in immediately available funds at the Funding Office by 2:00 P.M., New York City time, on the date on which such payment shall be due, provided that if any payment hereunder would become due and payable on a day other than a Business Day such payment shall become due and payable on the next succeeding Business Day and, with respect to payments of principal, interest thereon shall be payable at the then applicable rate during such extension.

(c) Unless the Administrative Agent shall have been notified in writing by the Borrower prior to the date of any payment due to be made by the Borrower hereunder that the Borrower will not make such payment to the Administrative Agent, the Administrative Agent may assume that the Borrower is making such payment, and the Administrative Agent may, but shall not be required to, in reliance upon such assumption, make available to the Lenders their respective pro rata shares of a corresponding amount. If such payment is not made to the Administrative Agent by the Borrower within three Business Days after such due date, the Administrative Agent shall be entitled to recover, on demand, from each Lender to which any amount which was made available pursuant to the preceding sentence, such amount with interest thereon at the rate per annum equal to the daily average Federal Funds Effective Rate. Nothing herein shall be deemed to limit the rights of the Administrative Agent or any Lender against the Borrower.

2.11. Limitations on Eurodollar Tranches. Notwithstanding anything to the contrary in this Agreement, all borrowings, conversions and continuations of Eurodollar Loans and all selections of Interest Periods shall be in such amounts and be made pursuant to such elections so that, (a) after giving effect thereto, the aggregate principal amount of the Eurodollar Loans comprising each Eurodollar Tranche shall be equal to $1,000,000 or a whole multiple of $1,000,000 in excess thereof and (b) no more than six Eurodollar Tranches shall be outstanding at any one time.

2.12. Indemnity. The Borrower agrees to indemnify each Lender and the Administrative Agent for, and to hold each Lender and the Administrative Agent harmless from, any actual loss or expense that such Lender or Administrative Agent may sustain or incur as a consequence of (a) default by the Borrower in making a borrowing of, conversion into or continuation of Eurodollar Loans after the Borrower has given a notice requesting the same in accordance with the provisions of this Agreement, (b) default by the Borrower in making any prepayment of or conversion from Eurodollar Loans after the Borrower has given a notice thereof in accordance with the provisions of this Agreement or (c) the making of a prepayment of Eurodollar Loans on a day that is not the last day of an Interest Period with respect thereto. Such indemnification may include an amount equal to the excess, if any, of (i) the amount of interest that would have accrued on the amount so prepaid, or not so borrowed, converted or continued, for the period from the date of such prepayment or of such failure to borrow, convert or continue to the last day of such Interest Period (or, in the case of a failure to borrow, convert or continue, the Interest Period that would have commenced on the date of such failure) in each case at the

applicable rate of interest for such Loans provided for herein (excluding, however, the Applicable Margin included therein, if any) over (ii) the amount of interest (as reasonably determined by such Lender) that would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank eurodollar market. A certificate as to any amounts payable pursuant to this Section submitted to the Borrower by any Lender or Administrative Agent shall, to the extent permitted by applicable law, constitute prima facie evidence of the amounts claimed due. This covenant shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

2.13. Requirements of Law. (a) If the adoption of or any change in any Requirement of Law or in the interpretation or application thereof or compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority, in each case, made subsequent to the date hereof:

(i) shall subject any Lender to any tax of any kind whatsoever with respect to this Agreement or any Eurodollar Loan made by it or change the basis of taxation of payments to such Lender in respect thereof (except for Non-Excluded Taxes or Excluded Taxes covered by Section 2.14 and changes in the rate of tax on the overall net income of such Lender); or

(ii) shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of such Lender that is not otherwise included in the determination of the Eurodollar Rate; or

(iii) shall impose on such Lender any other condition; and the result of any of the foregoing is to increase the cost to such Lender, by an amount that such Lender deems to be material, of making, converting into, continuing or maintaining Eurodollar Loans or to reduce any amount receivable hereunder in respect thereof, then, in any such case, the Borrower shall promptly pay such Lender, upon its demand, any additional amounts necessary to compensate such Lender for such increased cost or reduced amount receivable. If any Lender becomes entitled to claim any additional amounts pursuant to this paragraph, it shall promptly notify the Borrower (with a copy to the Administrative Agent) of the event by reason of which it has become so entitled.

(b) If any Lender shall have determined that the adoption of or any change in any Requirement of Law regarding capital adequacy or in the interpretation or application thereof or compliance by such Lender or any corporation controlling such Lender with any request or directive regarding capital adequacy (whether or not having the force of law) from any Governmental Authority made subsequent to the date hereof shall have the effect of reducing the rate of return on such Lender’s or such corporation’s capital as a consequence of its obligations hereunder to a level below that which such Lender or such corporation could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s or such corporation’s policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, after submission by such Lender to the Borrower (with a copy to the Administrative Agent) of a written request therefor, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender or such corporation for such reduction.

(c) A certificate as to any additional amounts payable pursuant to this Section submitted by any Lender to the Borrower (with a copy to the Administrative Agent) shall be conclusive in the absence of manifest error. Notwithstanding anything to the contrary in this Section, the Borrower shall

not be required to compensate a Lender pursuant to this Section for any amounts incurred more than 180 days prior to the date that such Lender notifies the Borrower of such Lender’s intention to claim compensation therefor; provided that, if the circumstances giving rise to such claim have a retroactive effect, then such 180 days period shall be extended to include the period of such retroactive effect. The obligations of the Borrower pursuant to this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

2.14. Taxes. (a) All payments made by the Borrower under this Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority. If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Non-Excluded Taxes”) or Other Taxes are required to be withheld from any amounts payable to the Administrative Agent or any Lender hereunder, the amounts so payable to the Administrative Agent or such Lender shall be increased to the extent necessary to yield to the Administrative Agent or such Lender (after payment of all Non-Excluded Taxes and Other Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement, provided, however, that the Borrower shall not be required to increase any such amounts payable to any Lender with respect to any Excluded Taxes. “Excluded Taxes” are any Taxes (i) that are attributable to such Lender’s failure to comply with the requirements of paragraph (d) or (e) of this Section or (ii) that are United States withholding taxes imposed on amounts payable to such Lender at the time such Lender becomes a party to this Agreement, except to the extent that such Lender’s assignor (if any) was entitled, at the time of assignment, to receive additional amounts from the Borrower with respect to such Non-Excluded Taxes pursuant to this paragraph, or (iii) net income taxes, gross receipt taxes (imposed in lieu of net income taxes) and franchise taxes (imposed in lieu of net income taxes) imposed on the Administrative Agent or any Lender as a result of a present or former connection between the Administrative Agent or such Lender and the jurisdiction of the Governmental Authority imposing such tax or any political subdivision or taxing authority thereof or therein (other than any such connection arising solely from the Administrative Agent or such Lender having executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement or any other Loan Document).

(b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) Whenever any Non-Excluded Taxes or Other Taxes are payable by the Borrower, as promptly as possible thereafter the Borrower shall send to the Administrative Agent for its own account or for the account of the relevant Lender, as the case may be, a certified copy of an original official receipt received by the Borrower (or other evidence acceptable to the Administration Agent in its sole discretion) showing payment thereof. If the Borrower fails to pay any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent the required receipts or other required documentary evidence, the Borrower shall indemnify the Administrative Agent and the Lenders for any incremental taxes, interest or penalties that may become payable by the Administrative Agent or any Lender as a result of any such failure.

(d) Each Lender (or Transferee) that is not a “U.S. Person” as defined in Section 7701(a)(30) of the Code (a “Non-U.S. Lender”) shall deliver to the Borrower and the Administrative Agent (or, in the case of a Participant, to the Lender from which the related participation shall have been purchased) two copies of either U.S. Internal Revenue Service Form W-8BEN or Form W-8ECI, or, in the case of a Non-U.S. Lender claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest”, a statement substantially in the form to be supplied by the Administrative Agent and a Form W-8BEN, or any subsequent versions

thereof or successors thereto, properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or a reduced rate of, U.S. federal withholding tax on all payments by the Borrower under this Agreement and the other Loan Documents. Such forms shall be delivered by each Non-U.S. Lender on or before the date it becomes a party to this Agreement (or, in the case of any Participant, on or before the date such Participant purchases the related participation). In addition, each Non-U.S. Lender shall deliver such forms promptly upon the obsolescence or invalidity of any form previously delivered by such Non-U.S. Lender. Each Non-U.S. Lender shall promptly notify the Borrower at any time it determines that it is no longer in a position to provide any previously delivered certificate to the Borrower (or any other form of certification adopted by the U.S. taxing authorities for such purpose). Notwithstanding any other provision of this paragraph, a Non-U.S. Lender shall not be required to deliver any form pursuant to this paragraph that such Non-U.S. Lender is not legally able to deliver.

(e) If the Administrative Agent or any Lender determines, in its good faith discretion, that it has received a refund of any Non-Excluded Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 2.14, it shall pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 2.14 with respect to the Non-Excluded Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided that the Borrower, upon the request of the Administrative Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. This paragraph shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person.

(f) The agreements in this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

2.15. Change of Lending Office. Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 2.13 or 2.14(a) with respect to such Lender, it will, if requested by the Borrower, use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Loans affected by such event with the object of avoiding the consequences of such event; provided that such designation is made on terms that, in the good faith judgment of such Lender, cause such Lender and its lending office(s) to suffer no economic, legal or regulatory disadvantage, and provided, further, that nothing in this Section shall affect or postpone any of the obligations of the Borrower or the rights of any Lender pursuant to Section 2.13 or 2.14(a).

2.16. Fees. (a) The Borrower agrees to pay to the Administrative Agent the fees in the amounts and on the dates from time to time agreed to in writing by the Borrower and the Administrative Agent.

(b) The Borrower agrees to pay on the Extension Date the fees set forth in the Amendment Letter.

2.17. Nature of Fees. All Fees shall be paid on the dates due, in immediately available funds, to the Administrative Agent (for the respective accounts of the Administrative Agent, the Joint

Lead Arrangers and the Lenders), as provided herein. Once paid, none of the Fees shall be refundable under any circumstances.

2.18. Priority and Liens. (a) The Borrower and each MCC Guarantor hereby covenant, represent and warrant that the Obligations of the Borrower and each MCC Guarantor hereunder and under the other Loan Documents were and as of the Extension Date continue to be, secured by a perfected first priority lien on all property of the Debtors, subject to Permitted Liens.

(b) As to all Collateral, including without limitation, all cash, Cash Equivalents and real property the title to which is held by any of the Borrower or any MCC Guarantor, or the possession of which is held by the Borrower or any MCC Guarantor in the form of a leasehold interest, such Loan Party hereby as of the date of entry of the Interim Order assigns and conveys as security, grants a security interest in, hypothecates, mortgages, pledges and sets over unto the Administrative Agent all of the right, title and interest of the Borrower and such MCC Guarantor in all of such Collateral, including without limitation, all cash, Cash Equivalents – MCC and owned real property and in all such leasehold interests, together in each case with all of the right, title and interest of the Borrower and such MCC Guarantor in and to all buildings, improvements, and fixtures related thereto, any lease or sublease thereof, all general intangibles relating thereto and all proceeds thereof to the extent constituting Collateral. The Borrower and each MCC Guarantor acknowledge that, pursuant to the Orders, the Liens granted in favor of the Administrative Agent (on behalf of the Lenders) in all of the Collateral were perfected without the recordation of any Uniform Commercial Code financing statements, notices of Lien or other instruments of mortgage or assignment. The Borrower and each MCC Guarantor further agree that (a) the Administrative Agent shall have the rights and remedies set forth in Section 10 in respect of the Collateral and (b) on the Extension Date the Borrower and each of the MCC Guarantors shall enter into separate security agreements, pledge agreements and fee and leasehold (if any) mortgages with respect to such Collateral on terms reasonably satisfactory to the Administrative Agent.

2.19. No Discharge; Survival of Claims. The Borrower and each MCC Guarantor agrees that its Obligations arising hereunder were not discharged by the entry of the Confirmation Order (and each of the Borrower and each MCC Guarantor, pursuant to Section 1141(d)(4) of the Bankruptcy Code, hereby waives any such discharge) and the Liens granted to the Administrative Agent pursuant to the Orders and described in Section 2.18 shall not be affected in any manner by the entry of a Confirmation Order.

The Administrative Agent may execute any of its duties under this Agreement and the other Loan Documents by or through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Administrative Agent shall not be responsible for the negligence or misconduct of any agents or attorneys-in-fact selected by it with reasonable care. The Administrative Agent shall be entitled to advice and opinion of legal counsel concerning all matters pertaining to the duties of the agencies hereby created.

8.3. Exculpatory Provisions. Neither the Administrative Agent nor any of their respective officers, directors, employees, agents, attorneys-in-fact or affiliates shall be (i) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Loan Document (except to the extent that any of the foregoing are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from its or such Person’s own gross negligence or willful misconduct) or (ii) responsible in any manner to any of the Lenders for any recitals, statements, representations or warranties made by any Loan Party or any officer thereof contained in this Agreement or any other Loan Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Agents under or in connection with, this Agreement or any other Loan Document or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or for any failure of any Loan Party a party thereto to perform its obligations hereunder or thereunder. The Administrative Agent shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of any Loan Party.

8.4. Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any instrument, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including counsel to the Borrower), independent accountants and other experts reasonably selected by the Administrative Agent. The Administrative Agent may deem and treat the payee of any Note as the owner thereof for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders (or, if so specified by this Agreement, all Lenders) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Required Lenders (or, if so specified by this Agreement, all Lenders), and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Loans.

8.5. Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default unless the Administrative Agent has received notice from a Lender, or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default”. In the event that the Administrative Agent receives such a notice, the Administrative Agent shall give notice thereof to the Lenders. The Administrative Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders (or, if so specified by this Agreement, all Lenders); provided

that unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders.

8.6. Non-Reliance on Agent and Other Lenders. Each Lender expressly acknowledges that neither the Administrative Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or affiliates have made any representations or warranties to it and that no act by the Administrative Agent hereafter taken, including any review of the affairs of the Borrower and its Subsidiaries or any affiliate of the Borrower and its Subsidiaries, shall be deemed to constitute any representation or warranty by the Administrative Agent to any Lender. Each Lender represents to the Administrative Agent that it has, independently and without reliance upon the Administrative Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the Borrower and its Subsidiaries and their affiliates and made its own decision to make its Loans hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon 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 analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Loan Parties and their affiliates. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent hereunder, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of the Borrower and its Subsidiaries or any affiliate of the Borrower and its Subsidiaries that may come into the possession of the Administration Agent or any of its officers, directors, employees, agents, attorneys-in-fact or affiliates.

8.7. Indemnification. The Lenders agree to indemnify the Administrative Agent in its capacity as such (to the extent not reimbursed by the Borrower and without limiting the obligation of the Borrower to do so), ratably according to their respective Aggregate Exposure Percentages in effect on the date on which indemnification is sought under this Section (or, if indemnification is sought after the date upon which the Commitments shall have terminated and the Loans shall have been paid in full, ratably in accordance with such Aggregate Exposure Percentages immediately prior to such date), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (whether before or after the payment of the Loans) be imposed on, incurred by or asserted against the Administrative Agent in any way relating to or arising out of, the Commitments, this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the Administrative Agent under or in connection with any of the foregoing, including without limitation, any action taken under Section 11.1(c) hereof; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements that are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the Administrative Agent’s gross negligence or willful misconduct. The agreements in this Section shall survive the payment of the Loans and all other amounts payable hereunder.

8.8. Agent in Its Individual Capacity. The Administrative Agent and its affiliates may make loans to, accept deposits from and generally engage in any kind of business with any Loan Party as though the Administrative Agent were not an Administrative Agent. With respect to its Loans made or renewed by it, the Administrative Agent shall have the same rights and powers under this

Agreement and the other Loan Documents as any Lender and may exercise the same as though it were not an Agent, and the terms “Lender” and “Lenders” shall include the Administrative Agent in its individual capacity.

8.9. Successor Administrative Agent. The Administrative Agent may resign as Administrative Agent upon 10 days’ notice to the Lenders and the Borrower. If the Administrative Agent shall resign as Administrative Agent under this Agreement and the other Loan Documents, then the Required Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall (unless an Event of Default shall have occurred and be continuing) be subject to approval by the Borrower (which approval shall not be unreasonably withheld or delayed and provided that the approval of the Borrower is not required for any Lender that was a Lender on the Extension Date), whereupon such successor agent shall succeed to the rights, powers and duties of the Administrative Agent, and the term “Administrative Agent” shall mean such successor agent effective upon such appointment and approval, and the former Administrative Agent’s rights, powers and duties as Administrative Agent shall be terminated, without any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement or any holders of the Loans. If no successor agent has accepted appointment as Administrative Agent by the date that is 10 days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective, and the Lenders shall assume and perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above. After any retiring Administrative Agent’s resignation as Administrative Agent, the provisions of this Section 8 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement and the other Loan Documents.

8.10. Replacement of Agent. The Required Lenders may request by notice to the Administrative Agent and the Borrower that the Administrative Agent resign. Upon receipt of any such notice the Administrative Agent shall resign, effective 10 days after receipt of such notice, as Administrative Agent under this Agreement and the other Loan Documents, and the Required Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall (unless an Event of Default shall have occurred and be continuing) be subject to approval by the Borrower (which approval shall not be unreasonably withheld or delayed and provided that the approval of the Borrower shall not be required for any Lender that was a Lender on the Extension Date), whereupon such successor agent shall succeed to the rights, powers and duties of the Administrative Agent, and the term “Administrative Agent” shall mean such successor agent effective upon such appointment and approval, and the former Administrative Agent’s rights, powers and duties as Administrative Agent shall be terminated, without any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement or any holders of the Loans. If no successor agent has accepted appointment as Administrative Agent by the date that is 10 days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective, and the Lenders shall assume and perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above. After any retiring Administrative Agent’s resignation as Administrative Agent, the provisions of this Section 8 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement and the other Loan Documents.

8.11. Duration of Agency. The agency established by Section 8.1 hereof shall continue, and Sections 8.1 through and including Section 8.13 shall remain in full force and effect, until the Notes and all other amounts due hereunder and thereunder shall have been paid in full and the Lenders’ commitments to extend credit to or for the benefit of the Borrower shall have terminated or expired.

8.12. Collateral Security. The Administrative Agent will hold, administer and manage any Collateral pledged from time to time hereunder either in its own name or as Administrative Agent, but each Lender shall hold a direct, undivided pro-rata beneficial interest therein, on the basis of its proportionate interest in the secured obligations, by reason of and as evidenced by this Agreement and the other Loan Documents.

8.13. Enforcement by the Administrative Agent. All rights of action under this Agreement and under the Notes and all rights to the Collateral hereunder may be enforced by the Administrative Agent and any suit or proceeding instituted by the Administrative Agent in furtherance of such enforcement shall be brought in its name as Administrative Agent without the necessity of joining as plaintiffs or defendants any other Lenders, and the recovery of any judgment shall be for the benefit of Lenders subject to the expenses of the Administrative Agent.

SECTION 9

GUARANTEE

9.1. Guarantee. (a) Each of the Guarantors hereby, jointly and severally, unconditionally and irrevocably, guarantees to the Administrative Agent, for the ratable benefit of the Lenders and their respective successors, indorsees, transferees and assigns permitted hereunder, the prompt and complete payment and performance by the Borrower when due (whether at the stated maturity, by acceleration or otherwise) of the Obligations.

(b) Anything herein or in any other Loan Document to the contrary notwithstanding, the maximum liability of each Guarantor under this Section 9.1 and under the other Loan Documents shall in no event exceed the amount which is permitted under applicable federal and state laws relating to the insolvency of debtors (after giving effect to the right of contribution established in Section 9.2).

(c) Each Guarantor agrees that the Obligations may at any time and from time to time exceed the amount of the liability of such Guarantor hereunder without impairing the guarantee contained in this Section 9 or affecting the rights and remedies of the Administrative Agent or any Lender hereunder.

(d) The guarantee contained in this Section 9 shall remain in full force and effect until all the Obligations and the obligations of each Guarantor under the guarantee contained in this Section 9 shall have been satisfied by payment in full and the Commitments shall be terminated, notwithstanding that from time to time during the term of this Agreement the Borrower may be free from any Obligations.

(e) No payment made by the Borrower, any of the Guarantors, any other guarantor or any other Person or received or collected by the Administrative Agent or any Lender from the Borrower, any of the Guarantors, any other guarantor or any other Person by virtue of any action or proceeding or any set-off or appropriation or application at any time or from time to time in reduction of or in payment of the Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of any Guarantor hereunder which shall, notwithstanding any such payment (other than any payment made by such Guarantor in respect of the Obligations or any payment received or collected from such Guarantor in respect of the Obligations), remain liable for the Obligations up to the maximum liability of such Guarantor hereunder until the Obligations are paid in full and the Commitments are terminated.

9.2. Right of Contribution. Each Subsidiary Guarantor hereby agrees that to the extent that a Subsidiary Guarantor shall have paid more than its proportionate share of any payment made

hereunder, such Subsidiary Guarantor shall be entitled to seek and receive contribution from and against any other Subsidiary Guarantor hereunder which has not paid its proportionate share of such payment. Each Subsidiary Guarantor’s right of contribution shall be subject to the terms and conditions of Section 9.3. The provisions of this Section 9.2 shall in no respect limit the obligations and liabilities of any Subsidiary Guarantor to the Administrative Agent and the Lenders, and each Subsidiary Guarantor shall remain liable to the Administrative Agent and the Lenders for the full amount guaranteed by such Subsidiary Guarantor hereunder.

9.3. Subrogation. Notwithstanding any payment made by any Guarantor hereunder or any set-off or application of funds of any Guarantor by the Administrative Agent or any Lender, no Guarantor shall be entitled to be subrogated to any of the rights of the Administrative Agent or any Lender against the Borrower or any other Guarantor or any collateral security or guarantee or right of offset held by the Administrative Agent or any Lender for the payment of the Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the Borrower or any other Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Administrative Agent and the Lenders by the Borrower on account of the Obligations are paid in full and the Commitments are terminated. Upon payment in full of the Obligations and termination of the Commitments, each Guarantor shall be subrogated to the rights of the Administrative Agent and the Lenders to the extent of any payment made by such Guarantor hereunder. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the Obligations shall not have been paid in full, such amount shall be held by such Guarantor in trust for the Administrative Agent and the Lenders, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Administrative Agent in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Administrative Agent, if required), to be applied against the Obligations, whether matured or unmatured, in accordance with the terms of this Agreement.

9.4. Amendments, etc. with respect to the Obligations. Each Guarantor shall remain obligated hereunder notwithstanding that, without any reservation of rights against any Guarantor and without notice to or further assent by any Guarantor, any demand for payment of any of the Obligations made by the Administrative Agent or any Lender may be rescinded by the Administrative Agent or such Lender and any of the Obligations continued, and the Obligations, or the liability of any other Person upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Administrative Agent or any Lender, and this Agreement and the other Loan Documents and any other documents executed and delivered in connection herewith or therewith may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent (or the Required Lenders or all Lenders, as the case may be) may deem advisable from time to time, and any collateral security, guarantee or right of offset at any time held by the Administrative Agent or any Lender for the payment of the Obligations may be sold, exchanged, waived, surrendered or released. Neither the Administrative Agent nor any Lender shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Obligations or for the guarantee contained in this Section 9 or any property subject thereto.

9.5. Guarantee Absolute and Unconditional. Each Guarantor waives any and all notice of the creation, renewal, extension or accrual of any of the Obligations and notice of or proof of reliance by the Administrative Agent or any Lender upon the guarantee contained in this Section 9 or acceptance of the guarantee contained in this Section 9; the Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended or waived, in reliance upon the guarantee contained in this Section 9; and all dealings between the Borrower and any of the Guarantors, on the one hand, and the Administrative Agent and the Lenders, on the other hand, likewise shall be conclusively presumed to have been had or consummated in reliance upon the

guarantee contained in this Section 9. Each Guarantor waives diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon the Borrower or any of the Guarantors with respect to the Obligations. Each Guarantor understands and agrees that the guarantee contained in this Section 9 shall be construed as a continuing, absolute and unconditional guarantee of payment without regard to (a) the validity or enforceability of this Agreement or any other Loan Document, any of the Obligations or any other collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by the Administrative Agent or any Lender, (b) any defense, set-off or counterclaim (other than a defense of payment or performance) which may at any time be available to or be asserted by the Borrower or any other Person against the Administrative Agent or any Lender, (c) any change in the corporate existence or structure of the Borrower or any other Person or any change in any law, regulation or order (including the Orders) affecting the Obligations, or (d) any other circumstance whatsoever (with or without notice to or knowledge of the Borrower or such Guarantor) which constitutes, or might be construed to constitute, an equitable or legal discharge of the Borrower for the Obligations, or of such Guarantor under the guarantee contained in this Section 9, in bankruptcy or in any other instance other than payment in full and indefeasible discharge and satisfaction of all Obligations. When making any demand hereunder or otherwise pursuing its rights and remedies hereunder against any Guarantor, the Administrative Agent or any Lender may, but shall be under no obligation to, make a similar demand on or otherwise pursue such rights and remedies as it may have against the Borrower, any other Guarantor or any other Person or against any collateral security or guarantee for the Obligations or any right of offset with respect thereto, and any failure by the Administrative Agent or any Lender to make any such demand, to pursue such other rights or remedies or to collect any payments from the Borrower, any other Guarantor or any other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of the Borrower, any other Guarantor or any other Person or any such collateral security, guarantee or right of offset, shall not relieve any Guarantor of any obligation or liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of the Administrative Agent or any Lender against any Guarantor. For the purposes hereof “demand” shall include the commencement and continuance of any legal proceedings.

9.6. Reinstatement. The guarantee contained in this Section 9 shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Obligations is rescinded or must otherwise be restored or returned by the Administrative Agent or any Lender upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of any Loan Party, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, any Loan Party or any substantial part of its property, or otherwise, all as though such payments had not been made.

9.7. Payments. Each Guarantor hereby guarantees that payments hereunder will be paid to the Administrative Agent without set-off or counterclaim in Dollars at the Funding Office.

SECTION 10

REMEDIES; APPLICATION OF PROCEEDS

10.1. Remedies; Obtaining the Collateral Upon Default. Upon the occurrence of the occurrence and continuation of any Event of Default, the Administrative Agent, in addition to any rights now or hereafter existing under applicable law shall have all rights as a secured creditor under the Uniform Commercial Code in all relevant jurisdictions and may:

(i) forthwith cause the same to be moved to the place or places so designated by the Administrative Agent and there delivered to the Administrative Agent,

(ii) store and keep any Collateral so delivered to the Administrative Agent at such place or places pending further action by the Administrative Agent, and

(iii) while the Collateral shall be so stored and kept, provide such guards and maintenance services as shall be necessary to protect the same and to preserve and maintain them in good condition ordinary wear and tear excepted;

it being understood that the Borrower’s and each MCC Guarantor’s obligation so to deliver the Collateral is of the essence of this Agreement and that, accordingly, the Administrative Agent shall be entitled to a decree requiring specific performance by the Borrower or such MCC Guarantor of such obligation.

10.2. Intentionally Deleted

10.3. Application of Proceeds. (a) Notwithstanding anything to the contrary contained in this Agreement or any other Loan Document but subject to the terms of the Intercreditor Agreements, (i) if the Administrative Agent takes action under clause (i) or (ii) of Section 7 upon the occurrence and during the continuance of an Event of Default, any payment by any Loan Party on account of principal of and interest on the Loans and any proceeds arising out of any realization (including after foreclosure) upon the Collateral shall be applied as follows: first, to the payment in full of all costs and out-of-pocket expenses (including without limitation, reasonable attorneys’ fees and disbursements) paid or incurred by the Administrative Agent or any of the Lenders in connection with any such realization upon the Collateral and in satisfaction and payment of any Cash Management Obligations and Hedging Agreement Obligations, and second to the payment in full of the Term Loans pro rata in accordance with the respective Term Loans outstanding to the Term Loan Lenders (including any accrued and unpaid interest, and any fees and other Obligations in respect thereof) and (ii) any payments or distributions of any kind or character, whether in cash, property or securities, made by any Loan Party or otherwise in a manner inconsistent with clause (i) of this Section 10.3(a) shall be held in trust and paid over or delivered to the Administrative Agent so that the priorities and requirements set forth in such clause (i) are satisfied.

(b) It is understood that the Loan Parties shall remain liable to the extent of any deficiency between the amount of the proceeds of the Collateral and the amount of the Obligations.

10.4. WAIVER OF CLAIMS. EXCEPT AS OTHERWISE PROVIDED IN THIS AGREEMENT, THE BORROWER AND THE GUARANTORS HEREBY WAIVE, TO THE EXTENT PERMITTED BY APPLICABLE LAW:

(A) NOTICE AND JUDICIAL HEARING IN CONNECTION WITH THE ADMINISTRATIVE AGENT’S TAKING POSSESSION OF ANY OF THE COLLATERAL, INCLUDING WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING FOR ANY PREJUDGMENT REMEDY OR REMEDIES AND ANY SUCH RIGHT WHICH THE BORROWER OR ANY GUARANTOR WOULD OTHERWISE HAVE UNDER ANY REQUIREMENT OF LAW;

(B) ALL DAMAGES OCCASIONED BY SUCH TAKING OF POSSESSION EXCEPT ANY DAMAGES WHICH ARE THE DIRECT RESULT OF THE ADMINISTRATIVE AGENT’S OR ANY LENDER’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT;

(D) ALL RIGHTS OF REDEMPTION, APPRAISEMENT, VALUATION, STAY, EXTENSION OR MORATORIUM NOW OR HEREAFTER IN FORCE UNDER ANY APPLICABLE LAW IN ORDER TO PREVENT OR DELAY THE ENFORCEMENT OF THIS AGREEMENT OR THE ABSOLUTE SALE OF THE COLLATERAL OR ANY PORTION THEREOF, AND EACH LOAN PARTY, FOR ITSELF AND ALL WHO MAY CLAIM UNDER IT, INSOFAR AS IT OR THEY NOW OR HEREAFTER LAWFULLY MAY, HEREBY WAIVES THE BENEFIT OF ALL SUCH LAWS.

10.5. Remedies Cumulative. Each and every right, power and remedy hereby specifically given to the Administrative Agent and the Lenders shall be in addition to every other right, power and remedy specifically given under this Agreement or the other Loan Documents or now or hereafter existing at law or in equity, or by statute and each and every right, power and remedy whether specifically herein given or otherwise existing may be exercised from time to time or simultaneously and as often and in such order as may be deemed expedient by the Administrative Agent or any Lender. All such rights, powers and remedies shall be cumulative and the exercise or the beginning of exercise of one shall not be deemed a waiver of the right to exercise of any other or others. No delay or omission of the Administrative Agent or any Lender in the exercise of any such right, power or remedy and no renewal or extension of any of the Obligations shall impair any such right, power or remedy or shall be construed to be a waiver of any Default or Event of Default or an acquiescence therein.

10.6. Discontinuance of Proceedings. In case the Administrative Agent shall have instituted any proceeding to enforce any right, power or remedy under this Agreement by foreclosure, sale, entry or otherwise, and such proceeding shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Administrative Agent, then and in every such case the Borrower, the Administrative Agent and each holder of any of the Obligations shall be restored to their former positions and rights hereunder with respect to the Collateral subject to the Liens granted under the Loan Documents and the Orders, and all rights, remedies and powers of the Administrative Agent and the Lenders shall continue as if no such proceeding had been instituted.

10.7. Attorney. (a) Each Loan Party hereby irrevocably constitutes and appoints the Administrative Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of such Loan Party and in the name of such Loan Party or in its own name, for the purpose of carrying out the terms of this Agreement, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Agreement. The Administrative Agent agrees that it will not exercise any rights under the power of attorney provided for in this Section 10.7(a) unless an Event of Default shall have occurred and be continuing.

(d) Each Loan Party as a grantor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof.

SECTION 11

MISCELLANEOUS

11.1. Amendments and Waivers. (a) None of this Agreement, any Note, any other Loan Document, nor any terms hereof or thereof may be amended, supplemented or modified except in accordance with the provisions of this Section 11.1. The Required Lenders may, or, with the written consent of the Required Lenders, the Administrative Agent may, from time to time, (I) enter into with the Loan Parties written amendments, supplements or modifications hereto, to the Notes and to the other Loan Documents for the purpose of adding any provisions to this Agreement, the Notes or the other Loan Documents or changing in any manner the rights of the Lenders or of the Loan Parties hereunder or thereunder or (II) waive, on such terms and conditions as the Required Lenders or the Administrative Agent, as the case may be, may specify in such instrument, any of the requirements of this Agreement, the Notes or the other Loan Documents or any Default or Event of Default and its consequences; provided, however, that no such waiver and no such amendment, supplement or modification shall (w) reduce the amount or extend the scheduled date of maturity of any Loan or other Extension of Credit or Note, or reduce the stated rate of any interest or fee payable hereunder (provided, however, that only the consent of the Required Lenders shall be necessary for the waiver of payment of default interest) or extend the scheduled date of any payment thereof or increase the amount or extend the expiration date of any Lender’s Commitment, in each case without the consent of each Lender directly affected thereby, (x) without the consent of all the Lenders, (i) amend, modify or waive any provision of this Section 11.1 or any other provision of any Section hereof expressly requiring the consent of all the Lenders, (ii) reduce the percentage specified in the definition of Required Lenders, (iii) release all or substantially all of the Collateral for the Obligations or (iv) consent to the assignment or transfer by any Loan Party of any of its rights and obligations under this Agreement and the other Loan Documents, or (y) amend, modify or waive any provision of Section 8 without the written consent of the Administrative Agent. Any such

waiver and any such amendment, supplement or modification shall apply equally to each of the Lenders and shall be binding upon the Loan Parties, the Lenders, the Administrative Agent and all future holders of the Notes. In the case of any waiver, the Loan Parties, the Lenders and the Administrative Agent shall be restored to their former position and rights hereunder and under the outstanding Notes and any other Loan Documents, and any Default or Event of Default waived shall be deemed to have not occurred or to be cured and not continuing, as the parties may agree; but no such waiver shall extend to any subsequent or other Default or Event of Default, or impair any right consequent thereon.

(b) Notwithstanding anything to the contrary contained in Section 11.1(a), in the event that the Borrower requests that this Agreement be modified or amended in a manner which would require the unanimous consent of all of the Lenders and such modification or amendment is agreed to by the Supermajority Lenders, then with the consent of the Borrower and the Supermajority Lenders, the Borrower and the Supermajority Lenders shall be permitted to amend the Agreement without the consent of the Lender or Lenders which did not agree to the modification or amendment requested by the Borrower (such Lender or Lenders, the “Minority Banks”) to provide for (w) the termination of the Commitment of each of the Minority Banks, (x) the addition to this Agreement of one or more other financial institutions (each of which shall be an Eligible Assignee), or an increase in the Commitment of one or more of the Supermajority Lenders, so that the aggregate of the Commitments after giving effect to such amendment shall be in the same amount as the aggregate of the Commitments immediately before giving effect to such amendment, (y) if any Loans are outstanding at the time of such amendment, the making of such additional Loans by such new financial institutions or Supermajority Lender or Lenders, as the case may be, as may be necessary to repay in full the outstanding Loans of the Minority Banks immediately before giving effect to such amendment and (z) such other modifications to this Agreement as may be appropriate.

(c) In the event that the Requisite Lenders (as defined in the Terra Credit Facility) and the borrowers under the Terra Credit Facility enter into any amendment, waiver or consent in respect of the Terra Credit Facility, then, if in the reasonable judgment of the Administrative Agent such amendment, waiver or consent does not directly or indirectly in any material respect impact the Borrower, the MCC Guarantors or the Trinidad Interests, such amendment, waiver or consent shall, by this reference, apply automatically to any comparable provision of this Agreement without the consent of any Lender and without any action by the Administrative Agent or any Lender.

No Indemnitee shall be liable for any damages (other than damages arising from the gross negligence and willful misconduct of such Indemnitee) arising from the use by unauthorized persons of Information or other materials sent through electronic, telecommunications or other information transmission systems that are intercepted by such persons or for any special, indirect, consequential or punitive damages in connection with this Agreement, the Loan Documents or any of the Loans made hereunder. Without limiting the foregoing, and to the extent permitted by applicable law, each Loan Party agrees not to assert and to cause its Subsidiaries not to assert, and hereby waives and agrees to cause its Subsidiaries so to waive, all rights for contribution or any other rights of recovery with respect to all claims, demands, penalties, fines, liabilities, settlements, damages, costs and expenses of whatever kind or nature, under or related to Environmental Laws, that any of them might have by statute or otherwise against any Indemnitee.

The agreements in this Section shall survive repayment of the Loans and all other amounts payable hereunder.

11.6. Successors and Assigns; Participations; Purchasing Lenders. (a) This Agreement shall be binding upon and inure to the benefit of the Loan Parties, the Lenders, the Administrative Agent all future holders of the Notes and their respective successors and assigns, except that neither the Borrower nor any Guarantor may assign or transfer any of its rights or obligations under this Agreement without the prior written consent of each Lender.

(b) Any Lender may, at its sole cost and expense, without notice to or consent of the Administrative Agent and the Borrower, in the ordinary course of its lending business and in accordance with applicable law, at any time sell to one or more banks or other entities (“Participants”) participating interests in any Loan owing to such Lender, any Note held by such Lender, any Commitment of such Lender or any other interest of such Lender hereunder and under the other Loan Documents. In the event of any such sale by a Lender of a participating interest to a Participant, such Lender’s obligations under this Agreement to the other parties to this Agreement shall remain unchanged, such Lender shall remain solely responsible for the performance thereof, such Lender shall remain the holder of any such Note for all purposes under this Agreement and the other Loan Documents, 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 and the other Loan Documents. No Lender shall grant any participation under which the Participant shall have the right to require such Lender to take or omit to take any action hereunder or approve any amendment to or waiver of this Agreement or the Notes or any other Loan Document, except to the extent such amendment or waiver would: (i) extend the final maturity date of, or extend any date for payment of any principal, interest or fees applicable to, the Loans, or Commitments in which such Participant is participating, (ii) reduce the interest rate or the amount of principal or fees applicable to the Loans in which such Participant is participating or (iii) release any Lien on all or substantially all of the Collateral. The Borrower agrees that if amounts outstanding under this Agreement and the Notes are due or unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each Participant shall be deemed to have the right of set off in respect of its participating interest in amounts owing under this Agreement and any Note to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement or any Note, provided that, in purchasing such participating interest, such Participant shall be deemed to have agreed to share with the Lenders the proceeds thereof as provided in Section 11.7(a) as fully as if it were a Lender hereunder. The Borrower also agrees that each Participant shall be entitled to the benefits of Sections 2.10 and 2.11 with respect to its participation in the Commitments and the Loans outstanding from time to time as if it were a Lender; and provided that the Participant and the transferor Lender shall not be entitled to receive in the aggregate any greater amount pursuant to such subsections than the transferor Lender would have been entitled to receive in respect of the amount of the participation transferred by such transferor Lender to such Participant had no such transfer occurred.

(c) Any Lender may, in the ordinary course of its business of making or investing in loans and in accordance with applicable law, at any time sell to any Lender or to one or more Eligible Assignees (each a “Purchasing Lender”) all or any part of its rights and obligations under this Agreement and the Notes pursuant to an Assignment and Acceptance, substantially in the form of Exhibit E, executed by such Purchasing Lender, such transferor Lender (and, in the case of a Purchasing Lender that is not then a Lender, by the Administrative Agent) and delivered to the Administrative Agent for its acceptance and recording in the Register; provided that (i) other than in the case of a sale to a Purchasing Lender that is an Affiliate of the transferor Lender or to another Lender, or to an Affiliate or Related Fund of any Lender (collectively, a “Related Party Transfer”), the consent of the Administrative Agent shall be required (which consent shall not be unreasonably withheld or delayed), (ii) other than in the case of a Related Party Transfer the consent of the Borrower shall be required (which consent shall not be unreasonably withheld or delayed), unless an Event of Default shall have occurred and is continuing, (iii) if such Purchasing Lender is not then a Lender, such sale must be to either (A) a commercial bank having total assets in excess of $5,000,000,000, (B) a finance company, insurance company or other financial

institution or fund which is regularly engaged in the making of, purchasing or investing in, loans and having total assets in excess of $100,000,000 or (C) such other Person approved by the Administrative Agent and the Borrower (which approval shall not be unreasonably withheld or delayed) (each, an “Eligible Assignee”) and (iv) if such sale is not to another Lender, Related Fund or Affiliate of any Lender, or does not involve all of the transferor Lender’s rights and obligations under this Agreement, (A) the amount of the rights and obligations so sold shall, unless otherwise agreed to in writing by the Administrative Agent, not be less than $5,000,000 (or the entire amount of its rights and obligations if less than $5,000,0000) and in each case to be an entity which is not an entity that has filed for relief under the Bankruptcy Code or is a financially distressed company and (B) after giving effect to such assignment, the Commitment of each of the transferor Lender and the transferee Lender shall be at least $5,000,000, or such lesser amount agreed to by the Administrative Agent and the Borrower. Upon such execution, delivery, acceptance and recording of an Assignment and Acceptance, from and after the effective date of such transfer determined pursuant to and as defined in such Assignment and Acceptance, (x) the Purchasing Lender thereunder shall be a party hereto and, to the extent provided in such Assignment and Acceptance, have the rights and obligations of a Lender hereunder with a Commitment as set forth therein, and (y) the transferor Lender thereunder shall, to the extent provided in such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of a Assignment and Acceptance covering all or the remaining portion of a transferor Lender’s rights and obligations under this Agreement, such transferor Lender shall cease to be a party hereto). Such Assignment and Acceptance shall be deemed to amend this Agreement (including Schedule 1.1A hereof) to the extent, and only to the extent, necessary to reflect the addition of such Purchasing Lender and the resulting adjustment of the Commitment of each of the transferor Lender and the Purchasing Lender arising from the purchase by such Purchasing Lender of all or a portion of the rights and obligations of such transferor Lender under this Agreement and the Notes. To the extent requested in writing by the transferor Lender or the Purchasing Lender on or prior to the effective date of such transfer determined pursuant to such Assignment and Acceptance, the Borrower, at its own expense, shall execute and deliver to the Administrative Agent in exchange for the Note of the transferor Lender a new Note to the order of such Purchasing Lender in an amount equal to the Commitment assumed by it pursuant to such Assignment and Acceptance and, if the transferor Lender has retained a Commitment hereunder, a new Note to the order of the transferor Lender in an amount equal to the Commitment retained by it hereunder. Such new Notes shall be dated the Closing Date and shall otherwise be in the form of the Note replaced thereby. To the extent the transferor Lender requested a Note pursuant to Section 2.5(e), the Note surrendered by the transferor Lender shall be returned by the Administrative Agent to the Borrower marked “cancelled”.

(d) The Administrative Agent, acting on behalf of the Borrower, shall maintain at its address referred to in Section 11.2 a copy of each Assignment and Acceptance delivered to it and a register (the “Register”) for the recordation of the names and addresses of the Lenders and the Commitment of, and principal amount of the Loans owing to, each Lender from time to time. The entries in the Register shall be presumptive evidence, in the absence of manifest error, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register as the owner of the Loans recorded therein for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice. Any assignment of any Loan whether or not evidenced by a Note shall be effective only upon appropriate entries with respect thereto being made in the Register (and each Note shall expressly so provide). Any assignment or transfer of all or part of a Loan evidenced by a Note shall be registered on the Register only upon surrender for registration of assignment or transfer of the Note evidencing such Loan, accompanied by a duly executed Assignment and Acceptance, and thereupon one or more new Notes in the same aggregate principal amount shall be issued to the designated Purchasing Lender and the old Notes shall be returned by the Administrative Agent to the Borrower marked “cancelled”.

(e) Upon its receipt of an Assignment and Acceptance executed by a transferor Lender and a Purchasing Lender (and, in the case of a Purchasing Lender that is not then a Lender, by the Administrative Agent and the Borrower to the extent required under paragraph (c) above) together with payment to the Administrative Agent of a registration and processing fee of $3,500, the Administrative Agent shall (i) promptly accept such Assignment and Acceptance, (ii) on the effective date of such transfer determined pursuant thereto record the information contained therein in the Register and (iii) give notice of such acceptance and recordation to the Lenders and the Borrower.

(f) Subject to Section 11.12, the Borrower authorizes each Lender to disclose to any Participant or Purchasing Lender (each, a “Transferee”) and any prospective Transferee (in each case which agrees to comply with the provisions of Section 11.12 hereof) any and all financial information in such Lender’s possession concerning the Borrower and its Affiliates which has been delivered to such Lender by or on behalf of the Borrower pursuant to this Agreement or any other Loan Document or which has been delivered to such Lender by or on behalf of the Borrower in connection with such Lender’s credit evaluation of the Borrower and its Affiliates prior to becoming a party to this Agreement.

(g) Nothing herein shall prohibit any Lender from pledging or assigning any Note to any Federal Reserve Bank in accordance with applicable law. In the case of any Lender that is a fund that invests in bank loans, such Lender may, without the consent of the Borrower or the Administrative Agent, assign or pledge all or any portion of its Notes or any other instrument evidencing its rights as a Lender under this Agreement to any trustee for, or any other representative of, holders of obligations owed or securities issued, by such fund, as security for such obligations or securities; provided that any foreclosure or similar action by such trustee or representative shall be subject to the provisions of this Section 11.6 concerning assignments.

11.7. Adjustments; Set-off. (a) If any Lender (a “Benefited Lender”) shall at any time receive any payment of all or part of its Aggregate Outstandings, or interest thereon, or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set-off or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in respect of such other Lender’s Aggregate Outstandings, or interest thereon, such Benefited Lender shall purchase for cash from the other Lenders a participating interest in such portion of each such other Lender’s Loans owing to it, or shall provide such other Lenders with the benefits of any such payment or collateral, or the proceeds thereof, as shall be necessary to cause such Benefited Lender to share the excess payment or benefits of such payment or collateral or proceeds ratably with each of the Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such Benefited Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest.

(b) Notwithstanding any other rights and remedies of the Lenders provided by law, each Lender, or Affiliate of such Lender shall have the right upon the occurrence and during the continuance of an Event of Default to set-off and apply against the Obligations, whether matured or unmatured, of the Loan Parties under this Agreement, the Notes or any other Loan Document, any amount owing from such Lender or Affiliate to any Loan Party at or at any time after, the happening of any Event of Default.

11.11. Intentionally Deleted.

11.12. Confidentiality. Each Lender agrees to keep confidential all non-public information provided to it by any Loan Party pursuant to this Agreement; provided that nothing herein shall prevent any Lender from disclosing any such information (a) to the Administrative Agent or any other Lender, (b) to any Transferee or prospective Transferee which agrees to comply with the provisions of this subsection, (c) to its employees, directors, agents, attorneys, accountants and other professional advisors that agree to comply with the provisions of this Section, (d) upon the request or demand, or in accordance with the requirements (including reporting requirements), of any Governmental Authority having jurisdiction over such Lender, provided that such Lender shall provide notice to the Borrower of such request or demand (e) in response to any court or other Governmental Authority or as may otherwise be required pursuant to any Requirement of Law, (f) which has been publicly disclosed other than in breach of this Agreement, (g) in connection with the exercise of any remedy hereunder, (h) which was available to the Administrative Agent or such Lender prior to its disclosure to the Administrative Agent or such Lender, as the case may be, by such Loan Party or (i) to any direct or indirect contractual counterparty in any swap, hedge or similar agreement (or to any such contractual counterparty’s professional advisor), so long as such contractual counterparty (or such professional advisor) agrees to be bound by the provisions of this Section 11.12.

11.13. Integration. This Agreement and the other Loan Documents represent the entire agreement of the Borrower, the Guarantors, the Administrative Agent, the Joint Lead Arrangers and the
