communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided, that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by the Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under any Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of the applicable Letter of Credit, the Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of the applicable Letter of Credit.

(f)            Disbursement Procedures. The Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under each Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether the Issuing Bank has made or will make an LC Disbursement thereunder; provided, that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank and the Lenders with respect to any such LC Disbursement.

(g)           Interim Interest. If the Issuing Bank shall make any LC Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC Disbursement, at the Alternate Base Rate; provided, that, if the Borrower fails to reimburse such LC Disbursement when due pursuant to paragraph (d) of this Section, the unpaid amount thereof shall bear interest, for each day from and including the date of such LC Disbursement to but excluding the date that the Borrower reimburses such LC Disbursement at a rate per annum equal to 2% plus the Alternate Base Rate. Interest accrued pursuant to this paragraph shall be for the account of the Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to paragraph (d) of this Section to reimburse the Issuing Bank shall be for the account of such Lender to the extent of such payment.

(h)           Cash Collateralization.

(i)            If any Event of Default shall occur and be continuing, on the Business Day that the Borrower receives notice from the Administrative Agent or the Required Lenders demanding the deposit of cash collateral pursuant to this paragraph, then the Borrower shall deposit in one or more accounts with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to the LC Exposure as of such date plus any accrued and unpaid interest thereon; provided, that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower described in clause (g) or (h) of Article VII. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the obligations of the Borrower under this Agreement (and, with respect cash collateral for the Initial Letter of Credit, subject to provisions in the Code related to the investment of monies pledged as security for tax-exempt bonds). The Administrative Agent shall have exclusive

19

dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time.

(ii)           If at any time the LC Exposure exceeds the aggregate Commitments, on the Business Day that the Borrower receives notice from the Administrative Agent or the Issuing Bank, then the Borrower shall immediately deposit in one or more accounts with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lender, an amount in cash equal to such excess. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the obligations of the Borrower under this Agreement. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time until such time as the LC Exposure does not exceed the aggregate Commitments.

Section 2.02           Termination of Commitments. Unless previously terminated, the Commitments shall terminate on the Maturity Date.

Section 2.03           Fees.

(a)           The Borrower agrees to pay (i) to the Administrative Agent for the account of each Lender a participation fee with respect to its participations in each Letter of Credit, which shall accrue at the rate of 0.75% per annum on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure, and (ii) to the Issuing Bank for its own account a fronting fee, which shall accrue at the rate of 0.125% per annum on the average daily amount of that portion of the LC Exposure attributable to the Issuing Bank (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure attributable to the Issuing Bank, as well as the Issuing Bank’s standard fees with respect to the issuance, amendment, renewal or extension of each Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees accrued through and including the last day of March, June, September and December of each year shall be payable on such last day, commencing on the first such date to occur after the Effective Date; provided, that all such fees shall be payable on the date on which the Commitments terminate and any such fees accruing after the date on which the Commitments terminate shall be payable on demand. Any other fees payable to the Issuing Bank pursuant to this paragraph shall be payable within 10 days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last).

20

(b)           The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately agreed upon between the Borrower and the Administrative Agent.

(c)           All fees payable hereunder shall be paid in Dollars on the dates due, in immediately available funds, to the Administrative Agent (or to the Issuing Bank, in the case of fees payable to it) for distribution, in the case of participation fees, to the Lenders. Fees paid shall not be refundable under any circumstances.

Section 2.04           Increased Costs.

(a)           If any Change in Law shall impose, modify or deem applicable any reserve, compulsory loan, insurance charge, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender or the Issuing Bank and the result of any of the foregoing shall be to increase the cost to such Lender or the Issuing Bank of participating in, issuing or maintaining any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender or the Issuing Bank hereunder, then the Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered.

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

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

(d)           Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation; provided, that the Borrower shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section for any increased costs or reductions incurred more than 270 days prior to the date that such Lender or the Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor; provided, further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof.

Section 2.05           Taxes.

(a)           Withholding Taxes; Gross-Up. Each payment by any Loan Party under any Loan Document shall be made without withholding for any Taxes, unless such withholding is required by law. If any Withholding Agent determines, in its sole discretion exercised in good faith, that

21

it is so required to withhold Taxes, then such Withholding Agent may so withhold and shall timely pay the full amount of withheld Taxes to the relevant Governmental Authority in accordance with applicable law. If such Taxes are Indemnified Taxes, then the amount payable by such Loan Party shall be increased as necessary so that net of such withholding (including withholding applicable to additional amounts payable under this Section) the applicable Recipient receives the amount it would have received had no such withholding been made.

(b)           Payment of Other Taxes by the Borrower. The Borrower shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c)           Evidence of Payment. As soon as practicable after any payment of Indemnified Taxes by any Loan Party to a Governmental Authority, such Loan Party shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(d)           Indemnification by the Loan Parties. The Loan Parties shall jointly and severally indemnify each Recipient for any Indemnified Taxes that are paid or payable by such Recipient in connection with any Loan Document (including amounts paid or payable under this Section 2.05(d) and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. The indemnity under this Section 2.05(d) shall be paid within 10 days after the Recipient delivers to any Loan Party a certificate stating the amount of any Indemnified Taxes so paid or payable by such Recipient or Beneficial Owner and describing the basis for the indemnification claim. Such certificate shall be conclusive of the amount so paid or payable absent manifest error. Such Recipient shall deliver a copy of such certificate to the Administrative Agent.

(e)           Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent for any Taxes (but, in the case of any Indemnified Taxes, only to the extent that any Loan Party has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Loan Parties to do so) attributable to such Lender that are paid or payable by the Administrative Agent in connection with any Loan Document and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. The indemnity under this Section 2.05(e) shall be paid within 10 days after the Administrative Agent or the applicable Loan Party (as applicable) delivers to the applicable Lender a certificate stating the amount of Taxes so paid or payable by the Administrative Agent or the applicable Loan Party (as applicable). Such certificate shall be conclusive of the amount so paid or payable absent manifest error.

(f)            Status of Lenders.

(i)            Any Lender that is entitled to an exemption from, or reduction of, any applicable withholding Tax with respect to any payments under any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without, or at a reduced rate of, withholding. In addition, any Lender, if requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to any withholding (including backup withholding) or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion,

22

execution and submission of such documentation (other than such documentation set forth in Section 2.05(f)(ii)(A) through (E) below and Section 2.05(f)(iii) below) shall not be required if in the Lender’s judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender. Upon the reasonable request of such Borrower or the Administrative Agent, any Lender shall update any form or certification previously delivered pursuant to this Section 2.05(f). If any form or certification previously delivered pursuant to this Section expires or becomes obsolete or inaccurate in any respect with respect to a Lender, such Lender shall promptly (and in any event within 10 days after such expiration, obsolescence or inaccuracy) notify such Borrower and the Administrative Agent in writing of such expiration, obsolescence or inaccuracy and update the form or certification if it is legally eligible to do so.

(ii)           Without limiting the generality of the foregoing, if the Borrower is a U.S. Person, any Lender with respect to such Borrower shall, if it is legally eligible to do so, deliver to such Borrower and the Administrative Agent (in such number of copies reasonably requested by such Borrower and the Administrative Agent) on or prior to the date on which such Lender becomes a party hereto, duly completed and executed copies of whichever of the following is applicable:

(A)          in the case of a Lender that is a U.S. Person, IRS Form W-9 certifying that such Lender is exempt from U.S. Federal backup withholding tax;

(B)           in the case of a Non-U.S. Lender claiming the benefits of an income tax treaty to which the United States is a party (1) with respect to payments of interest under any Loan Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. Federal withholding Tax pursuant to the “interest” article of such tax treaty and (2) with respect to any other applicable payments under this Agreement, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. Federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(C)           in the case of a Non-U.S. Lender for whom payments under this Agreement constitute income that is effectively connected with such Lender’s conduct of a trade or business in the United States, IRS Form W-8ECI;

(D)          in the case of a Non-U.S. Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code both (1) IRS Form W-8BEN and (2) a certificate substantially in the form of Exhibit E (a “U.S. Tax Certificate”) to the effect that such Lender is not (a) a “bank” within the meaning of Section 881(c)(3)(A) of the Code, (b) a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code (c) a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code and (d) conducting a trade or business in the United States with which the relevant interest payments are effectively connected;

(E)           in the case of a Non-U.S. Lender that is not the beneficial owner of payments made under this Agreement (including a partnership or a participating Lender) (1) an IRS Form W-8IMY on behalf of itself and (2) the relevant forms prescribed in clauses (A), (B), (C), (D) and (F) of this paragraph (f)(ii) that would be required of each such beneficial owner or partner of such partnership if such beneficial owner or partner were a Lender; provided, however, that if the Lender is a partnership and one or more of its partners are claiming the exemption for portfolio interest under Section 881(c) of the Code, such Lender may provide a U.S. Tax Certificate on behalf of such partners; or

(F)           any other form prescribed by law as a basis for claiming exemption from, or a reduction of, U.S. Federal withholding Tax together with such supplementary

23

documentation necessary to enable the Borrower or the Administrative Agent to determine the amount of Tax (if any) required by law to be withheld.

(iii)          If a payment made to a Lender under this Agreement or any other Loan Document would be subject to U.S. Federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Withholding Agent, at the time or times prescribed by law and at such time or times reasonably requested by the Withholding Agent, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Withholding Agent as may be necessary for the Withholding Agent to comply with its obligations under FATCA, to determine that such Lender has complied with such Lender’s obligations under FATCA and, as necessary, to determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 2.05(f)(iii), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(g)           Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 2.05 (including additional amounts paid pursuant to this Section 2.05), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including any Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid such indemnified party pursuant to the previous sentence (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything herein to the contrary in this Section 2.05(g), in no event will any indemnified party be required to pay any amount to any indemnifying party pursuant to this Section 2.05(g) if such payment would place such indemnified party in a less favorable position (on a net after-Tax basis) than such indemnified party would have been in if the indemnification payments or additional amounts giving rise to such refund had never been paid. This Section 2.05(g).shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes which it deems confidential) to the indemnifying party or any other Person.

(h)           Issuing Bank. For purposes of Section 2.05(e) and (f), the term “Lender” includes any Issuing Bank and any other recipient of any payment to be made by or on account of any obligation of the Borrower hereunder.

Section 2.06           Pro Rata Treatment; Sharing of Set-offs. (a) The Borrower shall make each payment required to be made by it hereunder (whether of fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.04 or Section 2.05, or otherwise) on the date when due, in Dollars in immediately available funds, without set-off or counterclaim, to the account of the Administrative Agent as designated in writing from time to time by the Administrative Agent to the Borrower and Lenders for such purpose, prior to 12:00 noon, New York City time. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent, except payments to be made directly to the Issuing Bank as expressly provided herein and except that payments pursuant to Section 2.04, Section 2.05, and Section 10.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person in like funds to the appropriate recipient, for the account

24

of its applicable Lending Office, promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in Dollars.

(b)           If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties.

(c)           If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any participations in LC Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its participations in LC Disbursements than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of participations in LC Disbursements; provided, that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in LC Disbursements to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(d)           Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the Issuing Bank hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or the Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(e)           If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.01(c) or (d), or Section 2.06(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid.

25

Section 2.07           Reduction of Letter of Credit by Amendment. The Initial Letter of Credit supports payment of the Bonds. If, from time to time, the Beneficiary and the Borrower desire to reduce the amount of the Initial Letter of Credit, the Borrower and the Beneficiary shall send a written notice to the Issuing Bank requesting that the Initial Letter of Credit be amended and specifying the amount by which the face amount of the Initial Letter of Credit shall be reduced and the date on which such amendment shall be effective. Upon receipt of such written notice, the Issuing Bank shall amend the Initial Letter of Credit to reduce its face amount. If the requested amendment reduces the Initial Letter of Credit to zero, the original Initial Letter of Credit shall be returned to the Issuing Bank and shall be canceled.

Section 2.08           Mitigation Obligations; Replacement of Lenders. (a) If any Lender requests compensation under Section 2.04, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.05, then such Lender shall use reasonable efforts to designate a different lending office for booking its Commitments hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.04 or Section 2.05, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b)           If any Lender requests compensation under Section 2.04, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.05, or if any Lender defaults in its obligation to acquire participations hereunder, then the Borrower may, at its sole expense and effort (including the payment by the Borrower of the fee specified in Section 10.04(b)(ii)(C)), upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 10.04), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided, that (i) the Borrower shall have received the prior written consent of the Administrative Agent (and, if a Commitment is being assigned, the Issuing Bank), which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.04 or payments required to be made pursuant to Section 2.05, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

ARTICLE VIII
MLP Guarantee

Section 8.01                                MLP Guarantee.

(a)                                  The MLP, to the maximum extent permitted by applicable law, (i) absolutely, unconditionally and irrevocably, guarantees to the Administrative Agent for the ratable benefit of the Guaranteed Creditors and their respective successors, endorsees, transferees and assigns, the prompt and complete payment and performance by the Borrower when due (whether at the stated maturity, by acceleration or otherwise) of the Borrower Obligations and (ii) indemnifies and holds harmless each Guaranteed Creditor from, and agrees to pay to such Guaranteed Creditor, all reasonable costs and expenses (including reasonable counsel fees and expenses) incurred by such Guaranteed Creditor in enforcing any of its rights under the guarantee contained in this Section 8.01. The MLP agrees that notwithstanding any stay, injunction or other prohibition preventing the payment by the Borrower of all or any portion of the Borrower Obligations and notwithstanding that all or any portion of the Borrower Obligations may be unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving the Borrower, to the maximum extent permitted by applicable law, such Borrower Obligations shall nevertheless be due and payable by the MLP for the purposes of this guarantee at the time such Borrower Obligations would by payable by the Borrower under the provisions of this Agreement. Notwithstanding the foregoing, any enforcement of this guarantee with respect to the rights of any Guaranteed Creditor shall be accomplished by the Administrative Agent acting on behalf of such Guaranteed Creditor. The guarantee contained in this Section 8.01 is a guarantee of payment and not collection, and the liability of the MLP is primary and not secondary. Anything to the contrary

43

notwithstanding, the maximum liability of the MLP under the guarantee provided for in this Article VIII shall in no event exceed the amount which can be guaranteed by the MLP under applicable federal and state laws relating to insolvency of debtors (after giving effect to any right of contribution provided for herein or in any other Loan Document).

(b)                                 The MLP agrees that if the maturity of the Borrower Obligations is accelerated by bankruptcy or otherwise, such maturity shall also be deemed accelerated for the purpose of this guarantee without demand or notice to the MLP. The guarantee contained in this Section 8.01 is a continuing guarantee and shall remain in full force and effect until all the Borrower Obligations and the obligations of the MLP under the guarantee contained in this Section 8.01 shall have been satisfied by payment in full in cash, no Letter of Credit shall be outstanding 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 Borrower Obligations.

(c)                                  No payment made by the Borrower, the MLP, any other guarantor or any other Person or received or collected by any Guaranteed Creditor from the Borrower, the MLP, 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 Borrower Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of the MLP hereunder which shall, notwithstanding any such payment (other than any payment made by the Borrower or MLP in respect of the Borrower Obligations or any payment received or collected from the Borrower or MLP in respect of the Borrower Obligations), remain liable for the Borrower Obligations until, subject to Section 8.05, the Borrower Obligations are paid in full in cash, no Letter of Credit shall be outstanding and the Commitments are terminated.

Section 8.02                                Subrogation. The MLP shall be subrogated to all the rights of any Guaranteed Creditor against the Borrower in respect of any amounts paid by the MLP pursuant to the provisions of the guarantee contained in Section 8.01; provided, however, that the MLP shall not be entitled to enforce or to receive any payments arising out of, or based upon, such right of subrogation with respect to any of the Borrower Obligations, nor shall the MLP seek or be entitled to seek any contribution or reimbursement from the Borrower or any other Guarantor (or any other guarantor) in respect of payments made by the MLP hereunder, until all of the Borrower Obligations and the Guarantees thereof shall have been indefeasibly paid in full in cash or discharged. A director, officer, employee or stockholder, as such, of the MLP shall not have any liability for any obligations of the MLP under the guarantee contained in Section 8.01 or any claim based on, in respect of or by reason of such obligations or their creation.

Section 8.03                                Amendments, etc. with respect to the Borrower Obligations. The MLP shall remain obligated hereunder notwithstanding that, without any reservation of rights against the MLP and without notice to or further assent by the MLP, any demand for payment of any of the Borrower Obligations made by any Guaranteed Creditor may be rescinded by such Guaranteed Creditor and any of the Borrower Obligations continued, and the Borrower 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 any Guaranteed Creditor, and any Loan Document and any other document executed and delivered in connection 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 any Guaranteed Creditor for the payment of the Borrower Obligations may be sold, exchanged, waived, surrendered or released. Except as required by applicable law, no Guaranteed Creditor shall have any obligation to protect, secure, perfect or insure any

44

Lien at any time held by it as security for the Borrower Obligations or for the guarantee contained in Section 8.01 or any property subject thereto.

Section 8.04                                Guarantee Absolute and Unconditional. To the fullest extent permitted by applicable law, the MLP hereby (a) waives diligence, presentment, demand of payment, notice of intent to accelerate, notice of acceleration, notice of acceptance, filing of claims with a court in the event of the merger, insolvency or bankruptcy of the Borrower or the MLP, and all demands and notices whatsoever, (b) acknowledges that any agreement, instrument or document evidencing the MLP Obligations may be transferred and that the benefit of its obligations hereunder shall extend to each holder of any agreement, instrument or document evidencing the MLP Obligations without notice to them and (c) covenants that the MLP Obligations will not be discharged except by complete performance thereof. The MLP further agrees that to the fullest extent permitted by applicable law, if at any time all or any part of any payment theretofore applied by any Person to any of the MLP Obligations is, or must be, rescinded or returned for any reason whatsoever, including without limitation, the insolvency, bankruptcy or reorganization of the MLP, such MLP Obligations shall, to the extent that such payment is or must be rescinded or returned, be deemed to have continued in existence notwithstanding such application, and the MLP Obligations shall continue to be effective or be reinstated, as the case may be, as though such application had not been made.

To the fullest extent permitted by applicable law, the obligations of the MLP under this guarantee shall be as aforesaid full, irrevocable, unconditional and absolute and shall not be impaired, modified, discharged, released or limited by any occurrence or condition whatsoever, including, without limitation, (i) any compromise, settlement, release, waiver, renewal, extension, indulgence or modification of, or any change in, any of the obligations and liabilities of the Borrower or the MLP contained in any of the Borrower Obligations or this Agreement, (ii) any impairment, modification, release or limitation of the liability of the Borrower, the MLP or any of their estates in bankruptcy, or any remedy for the enforcement thereof, resulting from the operation of any present or future provision of any applicable bankruptcy law, as amended, or other statute or from the decision of any court, (iii) the assertion or exercise by the Borrower or the MLP of any rights or remedies under any of the Borrower Obligations or this Agreement or their delay in or failure to assert or exercise any such rights or remedies, (iv) the assignment or the purported assignment of any property as security for any of the Borrower Obligations, including all or any part of the rights of the Borrower or the MLP under this Agreement, (v) the extension of the time for payment by the Borrower or the MLP of any payments or other sums or any part thereof owing or payable under any of the terms and provisions of any of the Borrower Obligations or this Agreement or of the time for performance by the Borrower or the MLP of any other obligations under or arising out of any such terms and provisions or the extension or the renewal of any thereof, (vi) the modification or amendment (whether material or otherwise) of any duty, agreement or obligation of the Borrower or the MLP set forth in this Agreement, (vii) the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially all of the assets, marshaling of assets and liabilities, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment of, or other similar proceeding affecting, the Borrower or any of the MLP or any of their respective assets, or the disaffirmance of any of the Borrower Obligations, or this Agreement in any such proceeding, (viii) the release or discharge of the Borrower or the MLP from the performance or observance of any agreement, covenant, term or condition contained in any of such instruments by operation of law, (ix) the unenforceability of any of the Borrower Obligations or this Agreement, (x) any change in the name, business, capital structure, corporate existence, or ownership of the Borrower or the MLP or any other person or entity liable on the obligations guaranteed hereby, (xi) the existence of any collateral or other guaranty, or any exchange, release or non-perfection of any collateral or other guaranty, or (xii) any other circumstance which might otherwise constitute a defense available to, or a legal or equitable discharge of, a surety or the MLP.

45

Section 8.05                                Reinstatement. To the maximum extent permitted by applicable law, the guarantee contained in Section 8.01 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 Borrower Obligations is rescinded or must otherwise be restored or returned by any Guaranteed Creditor upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Borrower or the MLP, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Borrower or the MLP or any substantial part of its property, or otherwise, all as though such payments had not been made.

Section 8.06                                Payments. The MLP hereby guarantees that payments hereunder will be paid to the Administrative Agent without set-off or counterclaim and without deduction for any taxes and in immediately available funds and in the relevant currency at the Administrative Agent’s payment office at the address provided in Section 10.01 of this Agreement.

ARTICLE IX
The Administrative Agent

Each of the Lenders and the Issuing Bank hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof, together with such actions and powers as are reasonably incidental thereto.

The bank serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent, and such bank 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 other Affiliate thereof as if it were not the Administrative Agent hereunder.

The Administrative Agent shall not have any duties or obligations except those expressly set forth herein. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that the Administrative Agent is required to exercise in writing as directed by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 10.02), and (c) except as expressly set forth herein, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 10.02) or in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement, (ii) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

46

The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any time by notifying the Lenders, the Issuing Bank and the Borrower. Upon any such resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent which shall be a Lender and a commercial bank with an office in New York, New York and having a combined capital and surplus of at least $500,000,000, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article and Section 10.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

Each Lender acknowledges 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 credit analysis and decision to enter into this Agreement. Each Lender also acknowledges 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 from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any related agreement or any document furnished hereunder or thereunder.

Section 10.02                          Waivers; Amendments. (a) No failure or delay by the Administrative Agent, the Issuing Bank or any Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the Issuing Bank and the Lenders hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have. Upon the occurrence of any Event of Default, the Administrative Agent or Issuing Bank may pursue any of their respective rights and remedies under any Loan Document or any Series 2010 Bond Document, as well as any other remedies available at law or in equity.   No waiver of any provision of this Agreement or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the issuance of any Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any Lender or the Issuing Bank may have had notice or knowledge of such Default at the time.

(b)                                 Neither this Agreement nor the Subsidiary Guaranty nor any provision hereof or thereof may be waived, amended or modified (except as expressly set forth herein or therein) except

48

pursuant to an agreement or agreements in writing entered into by the Borrower, the MLP and the Required Lenders or by the Borrower, the MLP and the Administrative Agent with the consent of the Required Lenders; provided, that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the amount of any LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the scheduled date of payment of the amount of any LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.06(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) waive or amend Section 4.01, Article VIII or release the MLP from its obligations hereunder or release any other Guarantor from a Subsidiary Guaranty (except as expressly set forth in the Subsidiary Guaranty) without the written consent of each Lender or (vi) change any of the provisions of this Section or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender; provided, further, that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, the Issuing Bank hereunder without the prior written consent of the Administrative Agent or the Issuing Bank, as the case may be. No later than three Business Days after the effectiveness of any amendment, consent or waiver under or in connection with the Revolving Credit Agreement, the Administrative Agent, the Issuing Bank and the Lenders shall enter into a substantially similar instrument with the Borrower and the MLP to the extent the provisions in the Revolving Credit Agreement which have been amended, consented to, or waived, are contained in this Agreement.

Section 10.03                          Expenses; Indemnity; Damage Waiver. (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of this Agreement or any amendments, modifications or waivers of the provisions hereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing Bank in connection with the issuance, amendment, renewal or extension of each Letter of Credit or any demand for payment thereunder and (iii) all out-of-pocket expenses incurred by the Administrative Agent, the Issuing Bank or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent, the Issuing Bank or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement or any Loan Document, including its rights under this Section, or in connection with any Letter of Credit issued hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of any Letter of Credit.

(b)                                 The Borrower shall indemnify the Administrative Agent, the Issuing Bank and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an Indemnitee) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) each Letter of Credit or the use of the proceeds therefrom (including any refusal by the Issuing Bank to honor a demand for payment under any Letter of Credit issued by it if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or

49

operated by the Borrower or any of its Subsidiaries, or any Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided, that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee.

(c)                                  To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent or the Issuing Bank under paragraph (a) or (b) of this Section (and without limiting the Borrower’s obligation to do so), each Lender severally agrees to pay to the Administrative Agent or the Issuing Bank, as the case may be, such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided, that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent or the Issuing Bank in its capacity as such.

(d)                                 To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Transactions, the Letter of Credit or the use of the proceeds thereof.

(e)                                  All amounts due under this Section shall be payable not later than 5 Business Days after written demand therefor.

Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues a Letter of Credit), Participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(A)                              the Borrower; provided, that no consent of the Borrower shall be required for an assignment to a Lender, an Affiliate of a Lender, or, if an Event of Default has occurred and is continuing, any other assignee;

(A)                              except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s Commitment of any Class, the amount of the Commitment of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 unless each of the Borrower and the Administrative Agent otherwise consent; provided, that no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing;

(B)                                each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement;

(C)                                the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; and

(D)                               the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

(iii)                               Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Section 2.05 and Section 10.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 10.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section.

(iv)                              The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and the amount of the LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the Register). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, the Issuing Bank and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, the Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v)                                 Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in

51

paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register; provided, that if either the assigning Lender or the assignee shall have failed to make any payment required to be made by it pursuant to Section 2.06(d) or Section 10.03(c), the Administrative Agent shall have no obligation to accept such Assignment and Assumption and record the information therein in the Register unless and until such payment shall have been made in full, together with all accrued interest thereon. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(c)                                  (i) Any Lender may, without the consent of the Borrower, the Administrative Agent, or the Issuing Bank, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment); provided, that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrower, the Administrative Agent, the Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided, that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 10.02(b) that affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Section 2.04 or Section 2.05 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.08 as though it were a Lender; provided such Participant agrees to be subject to Section 2.06(c) as though it were a Lender.

(ii)                                  A Participant shall not be entitled to receive any greater payment under Section 2.04 or Section 2.05 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.05 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.05(e) as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as an agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interests) of which Participant’s interest in the loans are after obligations under the Loan Documents (the “Participant Register”). Any such Participant Register shall be available for inspection by the Administrative Agent at any reasonable time and from time to time upon reasonable prior notice, provided, that the applicable Lender shall have no obligation to share such Participant Register to the Borrower except to the extent such disclosure is necessary to establish that such loan, commitment, letter of credit or other obligations is in required form to establish that such loan, commitment, letter of credit or other obligation is in required form under Section 5f.103-1(c) of the Treasury regulations. The entries in the Participant Register shall be conclusive, absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such Participant for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent shall have no responsibility to maintain a Participant Register.

(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

52

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.

Section 10.05                          Survival. All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the issuance of each Letter of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Section 2.04, Section 2.05 and Section 10.03 and Article IX shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the expiration or termination of each Letter of Credit and the Commitments or the termination of this Agreement or any provision hereof.

Section 10.06                          Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement, the other Loan Documents and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other required parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy or email transmission shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 10.07                          Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

Section 10.08                          Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower or the MLP against any of and all the obligations of the Borrower or the MLP now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

Section 10.09                          Governing Law; Jurisdiction; Consent to Service of Process. (a) This Agreement shall be construed in accordance with and governed by the law of the State of New York.

Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that the Administrative Agent, the Issuing Bank or any Lender may otherwise have to bring any action or proceeding relating to this Agreement against the Borrower or its properties in the courts of any jurisdiction.

(c)                                  The Borrower and the MLP each hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in paragraph (b) of this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d)                                 Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 10.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

EACH PARTY HERETO (a) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (b) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

OPINION OF COUNSEL FOR THE BORROWER AND THE MLP

June 5, 2012

To the Issuing Bank, Lenders and the Administrative

Agent Referred to Below

c/o Mizuho Corporate Bank, Ltd., as

Issuing Bank and Administrative Agent

1251 Avenue of the Americas

New York, New York 10020

Ladies and Gentlemen:

[I/We] have acted as counsel for NuStar Logistics, L.P. (the “Borrower”) and NuStar Energy L.P. (the “MLP” and each of the Subsidiaries of the MLP listed on Annex I hereto (the “Subsidiary Guarantors” and, together with the Borrower, the “Loan Parties”), in connection with the Letter of Credit Agreement dated as of June 5, 2012 (the “Reimbursement Agreement”), among the Borrower, the MLP, the banks and other financial institutions identified therein as Lenders, Mizuho Corporate Bank, Ltd., as Issuing Bank and Administrative Agent, and the other Loan Documents identified below. This opinion is being furnished to you pursuant to Section 4.01(b) of the Reimbursement Agreement. Unless otherwise defined herein, terms defined in the Reimbursement Agreement and used herein shall have the meanings given to them in the Reimbursement Agreement.

In that connection, we have examined executed copies of the Reimbursement Agreement and the Subsidiary Guaranty Agreement dated as of even date herewith made by each of the Guarantors (as defined therein) in favor of the Administrative Agent (the “Subsidiary Guaranty” and, together with the Reimbursement Agreement, the “Loan Documents”).

In addition, [I, or individuals under my direction,/We] have examined originals or copies, certified or otherwise identified to [my/our] satisfaction, of such documents, corporate records, certificates of public officials and other instruments and have conducted such other investigations of fact and law as [I/we] have deemed necessary or advisable for purposes of this opinion.

Upon the basis of the foregoing, [I am/we are] of the opinion that:

1.                                       The Loan Documents constitute the legal, valid and binding obligations of the Loan Parties party thereto, enforceable against such Loan Parties under the law of the State of New York in accordance with their respective terms.

2.                                       In a case properly argued and presented, a Texas court or a Federal court sitting in Texas and applying Texas conflict of law principles, as set out in Chapter 271 of the Texas Business and Commerce Code, would give effect to the provisions of the Reimbursement Agreement and the Subsidiary Guaranty selecting New York law as governing, and would apply the substantive laws of the State of New York in construing the Reimbursement Agreement and the Subsidiary Guaranty.

3.                                       Under the circumstances contemplated by the Reimbursement Agreement, the issuance of the Initial Letter of Credit and the extensions of credit to the Borrower under the Reimbursement Agreement will not violate Section 7 of the Securities Exchange Act of 1934, as amended, or any

1

regulation issued pursuant thereto, including without limitation, the provisions of Regulation T, U or X of the Board of Governors of the Federal Reserve System.

4.                                       No Loan Party is an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

5.                                       The Borrower (a) is a limited partnership duly formed and validly existing under the laws of the State of Delaware and (b) has the limited partnership power and authority to (i) own property and conduct the business in which it is currently engaged and in which it proposes, as of the date hereof, to be engaged after the date hereof, (ii) make, deliver and perform the Loan Documents to which it is a party in accordance with the terms and provisions thereof and (iii) incur the obligations under the Reimbursement Agreement.

7.                                       Each Subsidiary Guarantor (a) is a limited partnership, corporation or limited liability company validly existing under the laws of the jurisdiction of its formation as described on Annex I hereto and (b) has the limited partnership, corporate or limited liability company power and authority to make, deliver and perform the Subsidiary Guaranty in accordance with the terms and provisions thereof.

8.                                       The execution, delivery and performance of the Reimbursement Agreement by the Borrower and the MLP, and of the Subsidiary Guaranty by each Subsidiary Guarantor, and the obligations incurred by the Borrower under the Reimbursement Agreement, have been duly authorized by all necessary actions on behalf of the Loan Parties and each other Person whose authorization is relevant to, or constitutes, authorization on behalf of either Loan Party.

9.                                       The Loan Documents have been duly executed and delivered on behalf of the Loan Parties, as applicable.

10.                                 No approvals or consents of any governmental authority of the State of Texas or the United States of America or other consents or approvals by any other Person which have not been obtained on or prior to the date hereof are required (a) in connection with the participation by the Loan Parties in connection with the transactions under the Loan Documents or the execution, delivery and performance by any Loan Party of the Loan Documents to which it is a party, or (b) for the validity and enforceability of the Loan Documents and the exercise by the Administrative Agent, Issuing Bank, and Lenders of their respective rights and remedies thereunder.

11.                                 The execution, delivery and performance by the Loan Parties of the Loan Documents will not (a) violate any provision of the Partnership Agreement (Borrower), the Partnership Agreement (MLP), or the certificate of incorporation, bylaws, partnership agreement or limited liability company agreement, as applicable, of any Subsidiary Guarantor, (b) result in the breach of, or constitute a default under, any indenture or loan or credit agreement or any other material agreement, lease or instrument, known to me after due inquiry, to which any of the Loan Parties is a party or by which its properties may be bound, (c) result in, or require, the creation or imposition of any Lien on any of its properties or revenues pursuant to any requirement of law, rule regulation or order of any governmental authority of the State of Texas or the United States of America or material contractual obligation binding upon any

2

Loan Party, or (d) result in any violation by any Loan Party of any applicable law of the State of Texas or the United States of America.

12.                                 The Borrower is not subject to regulation under any statute or regulation of the State of Texas or the United States of America that limits its ability to incur indebtedness.

13.                                 To my knowledge (having made due inquiry with respect thereto), except as disclosed in the Reimbursement Agreement, no litigation, investigation or proceeding of or before any arbitrator or governmental authority is pending or threatened by or against any Loan Party or against any of the properties or revenues of either (a) with respect to the Loan Documents or any of the transactions contemplated thereby or (b) which, if adversely determined, could reasonably be expected to have a Material Adverse Effect.

(c)                                  Each Guarantor agrees that the Borrower 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 2 or affecting the rights and remedies of the Administrative Agent or any Lender hereunder.

(d)                                 The guarantee contained in this Section 2.1 shall remain in full force and effect until all the Borrower Obligations and the obligations of each Guarantor under the guarantee contained in this Section 2.1 shall have been satisfied by indefeasible payment in full in cash, no Letter of Credit shall be outstanding and the Commitments shall be terminated, notwithstanding that from time to time during the term of the Reimbursement Agreement the Borrower may be free from any Borrower Obligations.

The provisions of this Section 2.2 shall in no respect limit the obligations and liabilities of any Guarantor to the Administrative Agent and the Lenders, and each Guarantor shall remain liable to the Administrative Agent and the Lenders for the full amount guaranteed by such Guarantor hereunder.

2.3                                 No 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 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 Borrower Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the Borrower or any other Guarantor (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 Borrower Obligations are indefeasibly paid in full in cash, no Letter of Credit shall be outstanding and the Commitments are terminated. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the Borrower Obligations shall not have been paid in full in cash, 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 Borrower Obligations, whether matured or unmatured, in such order as the Administrative Agent may determine.

2.4                                 Amendments, etc. with respect to the Borrower 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 Borrower Obligations made by the Administrative Agent or any Lender may be rescinded by the Administrative Agent or such Lender and any of the Borrower Obligations continued, and the Borrower 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 the Reimbursement Agreement and the other Loan Documents and any other documents executed and delivered in connection 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 Borrower 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 Borrower Obligations or for the guarantee contained in this Section 2 or any property subject thereto.

2.5                                 Guarantee Absolute and Unconditional. Each Guarantor waives any and all notice of the creation, renewal, extension or accrual of any of the Borrower Obligations and notice of or proof of reliance by the Administrative Agent or any Lender upon the guarantee contained in this Section 2 or acceptance of the guarantee contained in this Section 2; the Borrower 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 2; and all dealings between the Borrower

Administrative Agent or any Lender to comply with any provision of applicable law in enforcing any security interest in or lien upon any such property, including any failure of the Administrative Agent or any Lender to dispose of any such property in a commercially reasonable manner, (p) any dealing whatsoever with the Borrower or other Person or any security, whether negligently or not, or any failure to do so, (q) any defense based upon or arising out any bankruptcy, insolvency, reorganization, moratorium, arrangement, readjustment of debt, liquidation or dissolution proceeding commenced by or against the Borrower or any other Person, including any discharge of, or bar against collecting, any of the Borrower Obligations, in or as a result of any such proceeding, (r) or any other act or omission to act or delay of any kind by the Borrower, the Administrative Agent, any Lender, any Guarantor or any other Person or any other circumstance whatsoever, whether similar or dissimilar to the foregoing, which might, but for the provisions of this Section 2.5, constitute a legal or equitable discharge, limitation or reduction of such Guarantor’s obligations hereunder (other than the indefeasible payment in full in cash of all of the Borrower Obligations). The foregoing provisions apply (and the foregoing waivers will be effective) even if the effect of any action (or failure to take any action) by the Administrative Agent or any Lender is to destroy or diminish a Guarantor’s subrogation rights, such Guarantor’s right to proceed against the Borrower for reimbursement, such Guarantor’s right to recover contribution from any other Guarantor or any other right or remedy. 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 Borrower 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.

2.6                                 Reinstatement. The guarantee contained in this Section 2 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 Borrower 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 the Borrower or any Guarantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Borrower or any Guarantor or any substantial part of its property, or otherwise, all as though such payments had not been made.

2.7                                 Payments. Each Guarantor hereby guarantees that payments hereunder will be paid to the Administrative Agent without set-off or counterclaim and without deduction for any taxes and in immediately available funds and in dollars at the Administrative Agent’s payment office as provided in Section 2.06 of the Reimbursement Agreement.

Section 3                                               REPRESENTATIONS AND WARRANTIES

To induce the Administrative Agent and the Lenders to enter into the Reimbursement Agreement, to induce the Issuing Bank to issue the Initial Letter of Credit, and to induce the Lenders to make their respective extensions of credit thereunder, each Guarantor hereby represents and warrants to the Administrative Agent and each Lender that:

6

3.1                                 Representations in Reimbursement Agreement. In the case of each Guarantor, the representations and warranties relating to subsidiaries of the Borrower and the MLP set forth in Article III of the Reimbursement Agreement, each of which is hereby incorporated herein by reference and shall apply mutatis mutandis, are true and correct, and the Administrative Agent and each Lender shall be entitled to rely on each of them as if they were fully set forth herein. Each Guarantor also represents and warrants that it is Solvent and that it is a Subsidiary of the MLP.

Section 4                                               COVENANTS

Each Guarantor covenants and agrees with the Administrative Agent and the Lenders that, from and after the date of this Agreement until the Obligations shall have been indefeasibly paid in full in cash, no Letter of Credit shall be outstanding and the Commitments shall have terminated, in the case of each Guarantor, such Guarantor shall take, or shall refrain from taking, as the case may be, each action that is necessary to be taken or not taken, as the case may be, so that no Default or Event of Default is caused by the failure to take such action or to refrain from taking such action by such Guarantor or any of its Subsidiaries.

Section 5                                               THE ADMINISTRATIVE AGENT

5.1                                 Authority of Administrative Agent. Each Guarantor acknowledges that the rights and responsibilities of the Administrative Agent under this Agreement with respect to any action taken by the Administrative Agent or the exercise or non-exercise by the Administrative Agent of any option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Agreement shall, as between the Administrative Agent and the Lenders, be governed by the Reimbursement Agreement and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Administrative Agent and the Guarantors, the Administrative Agent shall be conclusively presumed to be acting as agent for the Lenders with full and valid authority so to act or refrain from acting, and no Guarantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

Section 6                                               MISCELLANEOUS

6.1                                 Amendments in Writing. None of the terms or provisions of this Agreement may be waived, amended, supplemented or otherwise modified except in accordance with Section 10.02 of the Reimbursement Agreement.

6.2                                 Notices. All notices, requests and demands to or upon the Administrative Agent or any Guarantor hereunder shall be effected in the manner provided for in Section 10.01 of the Reimbursement Agreement; provided that any such notice, request or demand to or upon any Guarantor shall be addressed to such Guarantor at its notice address set forth on Schedule 1.

6.3                                 No Waiver by Course of Conduct; Cumulative Remedies. Neither the Administrative Agent nor any Lender shall by any act (except by a written instrument pursuant to Section 6.1), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default. No failure to exercise, nor any delay in exercising, on the part of the Administrative Agent or any Lender, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Administrative Agent or any Lender of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Administrative Agent or such Lender would

7

otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law.

6.4                                 Enforcement Expenses; Indemnification.

(a)                                  Each Guarantor agrees to pay or reimburse each Lender and the Administrative Agent for all its costs and expenses incurred in collecting against such Guarantor under the guarantee contained in Section 2 or otherwise enforcing or preserving any rights under this Agreement and which such Guarantor is a party, including, without limitation, the reasonable fees and disbursements of counsel (including the allocated fees and expenses of in-house counsel) to each Lender and of counsel to the Administrative Agent.

(b)                                 Each Guarantor agrees to pay, and to save the Administrative Agent and the Lenders harmless from, any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Agreement to the same extent the Borrower would be required to do so pursuant to Section 10.03 of the Reimbursement Agreement.

(c)                                  The agreements in this Section 6.4 shall survive repayment of the Obligations and all other amounts payable under the Reimbursement Agreement and the other Loan Documents.

6.5                                 Successors and Assigns.

A set of the copies of this Agreement signed by all the parties shall be lodged with the Borrower and the Administrative Agent. Delivery of an executed counterpart of a signature page of this Agreement by telecopy or facsimile shall be effective as delivery of a manually executed counterpart of this Agreement.

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

6.8                                 Integration. This Agreement and the other Loan Documents represent the entire agreement of the Guarantors, the Administrative Agent and the Lenders with respect to the subject matter hereof and thereof, and there are no promises, undertakings, representations or warranties by the Administrative Agent or any Lender relative to subject matter hereof and thereof not expressly set forth or referred to herein.

6.9                                 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK AND TO THE EXTENT CONTROLLING, LAWS OF THE UNITED STATES OF AMERICA.

(d)                                 agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction; and

(e)                                  waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this Section 6.10 any special, exemplary, punitive or consequential damages.
