The Administrative Agent is hereby authorized to charge the account of the Company maintained with the Administrative Agent (and/or its Affiliates) for each payment of principal, interest and fees as it becomes due hereunder.

2.10 Notes; Telephonic Notices. Each Bank is hereby authorized to record on the schedule attached to each of its Notes, or otherwise record in accordance with its usual practice, the date and amount of each of its Loans of the type evidenced by such Note; provided that neither the failure to so record nor any error in such recordation shall affect the Company’s obligations under any such Note. The Company hereby authorizes the Banks and the Administrative Agent to extend, convert or continue Advances, effect selections of Rate Options and transfer funds based on telephonic notices made by any person or persons the Administrative Agent or any Bank in good faith believes to be acting on behalf of the Company. The Company agrees to deliver promptly to the Administrative Agent a written confirmation, if such confirmation is requested by the Administrative Agent or any Bank, of each telephonic notice signed by a Responsible Officer. If the written confirmation differs in any material respect from the action taken by the Administrative Agent and the Banks, the records of the Administrative Agent and the Banks shall govern absent manifest error.

2.11 Interest Payment Dates; Interest and Fee Basis. Interest accrued on each Floating Rate Advance shall be payable on each Payment Date, commencing with the first such date to occur after the date hereof, and at maturity. Interest accrued on each Eurodollar Advance shall be payable on the last day of its applicable Interest Period, on any date on which the Eurodollar Advance is prepaid, whether by acceleration or otherwise, and at maturity. Interest accrued on each Eurodollar Advance having an Interest Period longer than three months shall also be payable on the last day of each three-month interval during such Interest Period. Interest and fees shall be calculated for actual days elapsed on the basis of a 360-day year, with the exception that interest on Floating Rate Advances shall be calculated on the basis of a 365 or 366 day year, as appropriate. Interest shall be payable for the day an Advance is made but not for the day of any payment on the amount paid if payment is received prior to noon (local time) at the place of payment. If any payment of principal of or interest on an Advance shall become due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and, in the case of a principal payment, such extension of time shall be included in computing interest in connection with such payment.

2.12 Notification of Advances, Interest Rates, Prepayments and Commitment Changes. Promptly after receipt thereof, the Administrative Agent will notify each Bank of the contents of each Aggregate Commitment reduction or increase notice, Borrowing Notice, Rate Option Notice and repayment notice received by it hereunder. The Administrative Agent will notify each Bank of the interest rate applicable to each Eurodollar Advance promptly upon determination of such interest rate and will give each Bank prompt notice of each change in the Alternate Base Rate.

2.13 Lending Installations. Each Bank may book its Loans at any Lending Installation selected by such Bank and may change its Lending Installation from time to time. All terms of this Agreement shall apply to any such Lending Installation and the Loans shall be deemed held by each Bank for the benefit of such Lending Installation. Each Bank may, by written or telex notice to the Administrative Agent and the Company, designate a Lending Installation through which Loans will be made by it and for whose account Loan payments are to be made.

2.14 Non-Receipt of Funds by the Administrative Agent. Unless the Company or a Bank, as the case may be, notifies the Administrative Agent prior to the date on which it is scheduled to make payment to the Administrative Agent of (i) in the case of a Bank, the proceeds of a Loan or (ii) in the case of the Company, a payment of principal, interest or fees to the Administrative Agent for the account of the Banks, that it does not intend to make such payment, the Administrative Agent may assume that such payment has been made. The Administrative Agent may, but shall not be obligated to, make the amount of such payment available to the intended recipient in reliance upon such assumption. If such Bank or the Company, as the case may be, has not in fact made such payment to the Administrative Agent, the recipient of such payment shall, on demand by the Administrative Agent, repay to the Administrative Agent the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Administrative Agent until the date the Administrative Agent recovers such amount at a rate per annum equal to (i) in the case of payment by a Bank, the Federal Funds Effective Rate for such day or (ii) in the case of payment by the Company, the interest rate applicable to the relevant Loan.

2.15 Replacement of Bank. If the Company is required pursuant to Section 3.01, 3.02 or 3.05 to make any additional payment to any Bank or if any Bank’s obligation to make or continue, or to convert Floating Rate Advances into, Eurodollar Advances shall be suspended pursuant to Section 3.03 (any Bank so affected, an “Affected Bank”), the Company may elect, if such amounts continue to be charged or such suspension is still effective, to replace such Affected Bank as a Bank party to this Agreement (unless such replacement would not reduce or eliminate such amounts or eliminate such suspension); provided that no Default or Event of Default shall have occurred and be continuing at the time of such replacement and such replacement would not result in the violation of any Requirement of Law by such Affected Bank; and provided, further, that, concurrently with such replacement, (A) another bank or other entity which is reasonably satisfactory to the Company and the Administrative Agent shall agree, as of such date, to purchase for cash the Advances and other Obligations due to such Affected Bank pursuant to an assignment substantially in the form of Exhibit F and to become a Bank for all purposes under this Agreement and to assume all obligations of such Affected Bank to be terminated as of such date and to comply with the requirements of Section 10.08 applicable to assignments (it being understood that such Affected Bank shall not be obligated to pay the processing fee described in Section 10.08(e)(ii) in connection with any such assignment) and (B) the Company shall pay to such Affected Bank in same day funds on the day of such replacement (1) all interest, fees and other amounts then accrued but unpaid to such Affected Bank by the Company hereunder to and including the date of termination, including without limitation payments due to such Affected Bank under Sections 3.01, 3.02 and 3.05, and (2) an amount, if any, equal to the payment which would have been due to such Bank on the day of such replacement under Section 3.04 had the Loans of such Affected Bank been prepaid on such date rather than sold to the replacement Bank.

2.16 Letters of Credit.

(a) Issuance. Each Issuer hereby agrees, on the terms and conditions set forth in this Agreement, to issue standby letters of credit (each a “Letter of Credit”) and to renew, extend, increase, decrease or otherwise modify Letters of Credit (“Modify,” and each such action a “Modification”) from time to time from and including the date of this Agreement and prior to the Termination Date upon the request of the Company; provided that immediately after each such Letter of Credit is issued (or, in the case of the Existing Letters of Credit, deemed issued hereunder) or Modified, (i) the aggregate amount of the outstanding Letter of Credit Obligations shall not exceed $75,000,000 (ii) the aggregate stated amount of Letters of Credit issued jointly for the account of the Company and Centennial International shall not exceed $50,000,000 and (iii) the Aggregate Outstanding Credit Exposure shall not exceed the Aggregate Commitment. No Letter of Credit shall have an expiry date later than the earlier of (x) one year after the issuance thereof and (y) five Business Days prior to the Termination Date.

(b) Participations. Upon the issuance or Modification by an Issuer of a Letter of Credit in accordance with this Section 2.16 (or, in the case of any Existing Letter of Credit, on the date hereof), such Issuer shall be deemed, without further action by any Person, to have unconditionally and irrevocably sold to each Bank, and each Bank shall be deemed, without further action by any Person, to have unconditionally and irrevocably purchased from such Issuer, a participation in such Letter of Credit (and each Modification thereof) and the related Letter of Credit Obligations in proportion to its Pro Rata Share.

(c) Notice. Subject to Section 2.16(a), the Company shall give the applicable Issuer notice prior to 10:00 a.m. (Minneapolis time) at least three Business Days (or such lesser period of time as such Issuer may agree in its sole discretion) prior to the proposed date of issuance or Modification of each Letter of Credit (other than an Existing Letter of Credit), (i) specifying the beneficiary, the proposed date of issuance (or Modification) and the expiry date of such Letter of Credit, (ii) describing the proposed terms of such Letter of Credit and the nature of the transactions proposed to be supported thereby and (iii) if such Letter of Credit is to be issued jointly for the account of the Company and Centennial International, confirming that, after giving effect to the issuance of such Letter of Credit, the Company is in compliance with the last sentence of Section 7.13. Upon receipt of such notice, such Issuer shall promptly notify the Administrative Agent, and the Administrative Agent shall promptly notify each Bank, of the contents thereof and of the amount of such Bank’s participation in such proposed Letter of Credit. The issuance or Modification by an Issuer of any Letter of Credit shall, in addition to the conditions precedent set forth in Article IV (the satisfaction of which such Issuer shall have no duty to ascertain, it being understood, however, that such Issuer shall not issue any Letter of Credit if it has received written notice from the Company, the Administrative Agent or any Bank that any such conditions precedent have not been satisfied), be subject to the conditions precedent that such Letter of Credit shall be satisfactory to such Issuer and that the Company shall have executed and delivered such application agreement and/or such other instruments and agreements relating to such Letter of Credit as such Issuer shall have reasonably requested (each a “Letter of Credit Application”). In the event of any conflict between the terms of this Agreement and the terms of any Letter of Credit Application, the terms of this Agreement shall control.

(d) Letter of Credit Fees. The Company shall pay to the Administrative Agent, for the account of the Banks ratably in accordance with their respective Pro Rata Shares, with respect to each Letter of Credit, a letter of credit fee (the “Letter of Credit Fee”) at a per annum rate equal to the Applicable Amount in effect from time to time on the maximum undrawn amount which may at any time thereafter be available under such Letter of Credit, such fee to be payable in arrears on each Payment Date, on the Termination Date and thereafter on demand. The Company shall also pay to each Issuer for its own account (x) a fronting fee in the amount agreed to by such Issuer and the Company from time to time, with such fee to be payable in arrears on each Payment Date, and (y) documentary and processing charges in connection with the issuance or Modification of and draws under the applicable Letters of Credit in accordance with such Issuer’s standard schedule for such charges as in effect from time to time.

(e) Administration; Reimbursement by Banks. Upon receipt from the beneficiary of any Letter of Credit of any demand for payment under such Letter of Credit, the applicable Issuer shall notify the Administrative Agent and the Administrative Agent shall promptly notify the Company and each other Bank as to the amount to be paid by such Issuer as a result of such demand and the proposed payment date (the “Letter of Credit Payment Date”). The responsibility of any Issuer to the Company and each Bank shall be only to determine that the documents delivered under each applicable Letter of Credit in connection with a demand for payment are in conformity in all material respects with such Letter of Credit. Each Issuer shall endeavor to exercise the same care in its issuance and administration of Letters of Credit as it does with respect to letters of credit in which no participations are granted, it being understood that in the absence of any gross negligence or willful misconduct by such Issuer, each Bank shall be unconditionally and irrevocably obligated, without regard to the occurrence of any Default or any condition precedent whatsoever, to reimburse such Issuer on demand for (i) such Bank’s Pro Rata Share of the amount of each payment made by such Issuer under each Letter of Credit to the extent such amount is not reimbursed by the Company pursuant to Section 2.16(f) below, plus (ii) interest on the foregoing amount, for each day from the date of the applicable payment by such Issuer to the date on which such Issuer is reimbursed by such Bank for its Pro Rata Share thereof, at a rate per annum equal to the Federal Funds Effective Rate or, beginning on third Business Day after demand for such amount by such Issuer, the rate applicable to Floating Rate Advances.

(f) Reimbursement by Company. The Company shall be irrevocably and unconditionally obligated to reimburse each Issuer on or before the applicable Letter of Credit Payment Date for any amount to be paid by such Issuer upon any drawing under any Letter of Credit, without presentment, demand, protest or other formalities of any kind; provided that the Company shall not be precluded from asserting any claim for direct (but not consequential) damages suffered by the Company to the extent, but only to the extent, caused by (i) the willful misconduct or gross negligence of such Issuer in determining whether a request presented under any Letter of Credit complied with the terms of such Letter of Credit or (ii) such Issuer’s failure to pay under any Letter of Credit after the presentation to it of a request strictly complying with the terms and conditions of such Letter of Credit. All such amounts paid by the applicable Issuer and remaining unpaid by the Company shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the sum of 2% plus the rate applicable to Floating Rate Advances. Each Issuer will pay to each Bank ratably in accordance with its Pro Rata Share all amounts received by it from the Company for application in payment, in whole or in part, of the Reimbursement Obligation in respect of any Letter of Credit issued by such Issuer, but only to the extent such Bank made payment to such Issuer in respect of such Letter of Credit pursuant to Section 2.16(e).

(g) Obligations Absolute. The Company’s obligations under this Section 2.16 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment which the Company may have or have had against the applicable Issuer, any Bank or any beneficiary of a Letter of Credit. The Company further agrees with each Issuer and the Banks that no Issuer or Bank shall be responsible for, and the Company’s Reimbursement Obligation in respect of any Letter of Credit shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, fraudulent or forged, or any dispute between or among the Company, any of its Affiliates, the beneficiary of any Letter of Credit or any financing institution or other party to whom any Letter of Credit may be transferred or any claims or defenses whatsoever of the Company or of any of its Affiliates against the beneficiary of any Letter of Credit or any such transferee. No Issuer shall be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit. The Company agrees that any action taken or omitted by the applicable Issuer or any Bank under or in connection with any Letter of Credit and the related drafts and documents, if done without gross negligence or willful misconduct, shall be binding upon the Company and shall not put such Issuer or any Bank under any liability to the Company. Nothing in this Section 2.16(g) is intended to limit the right of the Company to make a claim against the applicable Issuer for damages as contemplated by the proviso to the first sentence of Section 2.16(f).

(h) Actions of Issuer. Each Issuer shall be entitled to rely, and shall be fully protected in relying, upon any Letter of Credit, draft, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, facsimile, telex or teletype message, statement, order or other document believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel, independent accountants and other experts selected by such Issuer. Each Issuer shall be fully justified in failing or refusing to take any action under this Agreement unless it shall first have received such advice or concurrence of the Majority Banks as it reasonably deems appropriate or it shall first be indemnified to its reasonable satisfaction by the Banks against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. Notwithstanding any other provision of this Section 2.16, each Issuer shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement in accordance with a request of the Majority Banks, and such request and any action taken or failure to act pursuant thereto shall be binding upon the Banks and any future holder of a participation in any applicable Letter of Credit.

(i) Indemnification. The Company agrees to indemnify and hold harmless each Bank, the applicable Issuer and the Administrative Agent, and their respective directors, officers, agents and employees, from and against any and all claims and damages, losses, liabilities, costs or expenses which such Bank, such Issuer or the Administrative Agent may incur (or which may be claimed against such Bank, such Issuer or the Administrative Agent by any Person whatsoever) by reason of or in connection with the issuance, execution and delivery or transfer of or payment or failure to pay under any Letter of Credit or any actual or proposed use of any Letter of Credit, including any claims, damages, losses, liabilities, costs or expenses which such Issuer may incur by reason of or in connection with (i) the failure of any other Bank to fulfill or comply with its obligations to such Issuer hereunder (but nothing herein contained shall affect any right the Company may have against any defaulting Bank) or (ii) by reason of or on account of such Issuer issuing any Letter of Credit which specifies that the term “Beneficiary” therein includes any successor by operation of law of the named Beneficiary, but which Letter of Credit does not require that any drawing by any such successor Beneficiary be accompanied by a copy of a legal document, satisfactory to such Issuer, evidencing the appointment of such successor Beneficiary; provided that the Company shall not be required to indemnify any Bank, the applicable Issuer or the Administrative Agent for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the extent, caused by (x) the willful misconduct or gross negligence of such Issuer in determining whether a request presented under any Letter of Credit issued by such Issuer complied with the terms of such Letter of Credit or (y) such Issuer’s failure to pay under any Letter of Credit after the presentation to it of a request strictly complying with the terms and conditions of such Letter of Credit. Nothing in this Section 2.16(i) is intended to limit the obligations of the Company under any other provision of this Agreement.

(j) Banks’ Indemnification. Each Bank shall, ratably in accordance with its Pro Rata Share, indemnify each applicable Issuer and its affiliates and their respective directors, officers, agents and employees (to the extent not reimbursed by the Company) against any cost, expense (including reasonable counsel fees and charges), claim, demand, action, loss or liability (except such as result from such indemnitees’ gross negligence or willful misconduct or such Issuer’s failure to pay under any Letter of Credit after the presentation to it of a request strictly complying with the terms and conditions of such Letter of Credit) that such indemnitees may suffer or incur in connection with this Section 2.16 or any action taken or omitted by such indemnitees hereunder.

(k) LC Collateral Account. The Company agrees that it will establish on the Termination Date (or on such earlier date as may be required pursuant to Section 8.02), and thereafter maintain so long as any Letter of Credit is outstanding or any amount is payable to any Issuer or the Banks in respect of any Letter of Credit, a special collateral account pursuant to arrangements satisfactory to the Administrative Agent (the “LC Collateral Account”) at the Administrative Agent’s office at the address specified pursuant to Section 10.02, in the name of the Company but under the sole dominion and control of the Administrative Agent, for the benefit of the Banks, and in which the Company shall have no interest other than as set forth in Section 8.02. The Company hereby pledges, assigns and grants to the Administrative Agent, on behalf of and for the ratable benefit of the Banks and the Issuers, a security interest in all of the Company’s right, title and interest in and to all funds which may from time to time be on deposit in the LC Collateral Account, to secure the prompt and complete payment and performance of the Obligations. The Administrative Agent will invest any funds on deposit from time to time in the LC Collateral Account in certificates of deposit of U.S. Bank having a maturity not exceeding 30 days. If funds are deposited in the LC Collateral Account pursuant to this Section 2.16(k) and the provisions of Section 8.02 are not applicable, then the Administrative Agent shall release from the LC Collateral Account to the Company, upon the expiration or termination of, or any reduction in the amount available under, any Letter of Credit, an amount equal to the excess (if any) of all funds in the LC Collateral Account over the Letter of Credit Obligations.

(l) Rights as a Bank. In its capacity as a Bank, each Issuer shall have the same rights and obligations as any other Bank.

ARTICLE III

YIELD PROTECTION; TAXES

3.01 Yield Protection. If, on or after the date of this Agreement, the adoption of any law or any governmental or quasi-governmental rule, regulation, policy, guideline or directive (whether or not having the force of law), or any change in the interpretation or administration thereof by any governmental or quasi-governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank, any applicable Lending Installation or any Issuer with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency:

(a) subjects any Bank, any applicable Lending Installation or any Issuer to any Taxes, or changes the basis of taxation of payments (other than with respect to Excluded Taxes) to any Bank in respect of its Eurodollar Loans or Letters of Credit or participations therein, or

(b) imposes or increases or deems applicable any reserve, assessment, insurance charge, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Bank, any applicable Lending Installation or any Issuer (other than reserves and assessments taken into account in determining the interest rate applicable to Eurodollar Advances), or

(c) imposes any other condition the result of which is to increase the cost to any Bank, any applicable Lending Installation or any Issuer of making, funding or maintaining its Eurodollar Loans or of issuing or participating in Letters of Credit or reduces any amount receivable by any Bank or any applicable Lending Installation in connection with Letters of Credit or Eurodollar Loans, or requires any Bank, any applicable Lending Installation or any Issuer to make any payment calculated by reference to the amount of Letters of Credit or Eurodollar Loans held or interest received by it, by an amount deemed material by such Bank or such Issuer, as the case may be, and the result of any of the foregoing is to increase the cost to such Bank, the applicable Lending Installation or any Issuer of making or maintaining its Eurodollar Loans, Letters of Credit or Commitment or to reduce the return received by such Bank, the applicable Lending Installation or such Issuer in connection with such Eurodollar Loans, Letters of Credit or Commitment, then, within 15 days of demand by such Bank or such Issuer, the Company shall pay such Bank or such Issuer such additional amount or amounts as will compensate such Bank or such Issuer for such increased cost or reduction in amount received.

3.02 Changes in Capital Adequacy Regulations. If any Bank or any Issuer determines the amount of capital required or expected to be maintained by such Bank, any Lending Installation of such Bank, such Issuer or any corporation controlling such Bank or such Issuer is increased as a result of a Change, then, within 15 days of demand by such Bank or such Issuer, the Company shall pay such Bank or such Issuer the amount necessary to compensate for any shortfall in the rate of return on the portion of such increased capital which such Bank or such Issuer determines is attributable to this Agreement, its Loans, its Letters of Credit (or participations therein) or its Commitment to make Loans or to issue or participate in Letters of Credit hereunder (after taking into account such Bank’s policies as to capital adequacy). “Change” means (a) any change after the date of this Agreement in the Risk-Based Capital Guidelines or (b) any adoption of or change in any other law, governmental or quasi-governmental rule, regulation, policy, guideline, interpretation, or directive (whether or not having the force of law) after the date of this Agreement which affects the amount of capital required or expected to be maintained by any Bank, any Lending Installation, any Issuer or any corporation controlling any Bank or any Issuer. “Risk-Based Capital Guidelines” means (a) the risk-based capital guidelines in effect in the United States on the date of this Agreement, including transition rules, and (b) the corresponding capital regulations promulgated by regulatory authorities outside the United States implementing the July 1988 report of the Basle Committee on Banking Regulation and Supervisory Practices Entitled “International Convergence of Capital Measurements and Capital Standards,” including transition rules, and any amendments to such regulations adopted prior to the date of this Agreement.

3.03 Availability of Types of Advances. If (a) any Bank determines that maintenance of its Eurodollar Loans at a suitable Lending Installation would violate any applicable law, rule, regulation, or directive, whether or not having the force of law, or (b) if the Majority Banks determine that (i) deposits of a type and maturity appropriate to match fund Eurodollar Advances are not available or (ii) the interest rate applicable to Eurodollar Advances does not accurately reflect the cost of making or maintaining Eurodollar Advances, then the Administrative Agent shall suspend the availability of Eurodollar Advances and, in the case of clause (a) only, require any affected Eurodollar Advances to be repaid or converted to Floating Rate Advances, subject to the payment of any funding indemnification amounts required by Section 3.04.

3.04 Funding Indemnification. If any payment of a Eurodollar Advance occurs on a date which is not the last day of the applicable Interest Period, whether because of acceleration, prepayment or otherwise, or a Eurodollar Advance is not made on the date specified by the Company for any reason other than default by the Banks, the Company will indemnify each Bank for any loss or cost incurred by it resulting therefrom, including, without limitation, any loss or cost in liquidating or employing deposits acquired to fund or maintain such Eurodollar Advance.

3.05 Taxes. (a) All payments by the Company to or for the account of any Bank, any Issuer or the Administrative Agent hereunder or under any Note shall be made free and clear of and without deduction for any and all Taxes. If the Company shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder to any Bank, any Issuer or the Administrative Agent, (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 3.05) such Bank, such Issuer or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Company shall make such deductions, (iii) the Company shall pay the full amount deducted to the relevant authority in accordance with applicable law and (iv) the Company shall furnish to the Administrative Agent the original copy of a receipt evidencing payment thereof within 30 days after such payment is made.

(b) In addition, the Company hereby agrees to pay any present or future stamp or documentary taxes and any other excise or property taxes, charges or similar levies which arise from any payment made hereunder, under any Note or under any Letter of Credit Application or from the execution or delivery of, or otherwise with respect to, this Agreement, any Note or any Letter of Credit Application (“Other Taxes”).

(c) The Company hereby agrees to indemnify the Administrative Agent, each Bank and each Issuer for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed on amounts payable under this Section 3.05) paid by the Administrative Agent, such Bank or such Issuer and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. Payments due under this indemnification shall be made within 30 days of the date the Administrative Agent, such Bank or such Issuer makes demand therefor pursuant to Section 3.06.

(d) Each Bank that is not incorporated under the laws of the United States or a state thereof (each a “Non-U.S. Bank”) agrees that it will, not more than ten Business Days after the date of this Agreement, (i) deliver to each of the Company and the Administrative Agent two duly completed copies of IRS Form W-8BEN or W-8ECI, certifying in either case that such Bank is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, and (ii) deliver to each of the Company and the Administrative Agent an IRS Form W-8ECI or W-9, as the case may be, and certify that it is entitled to an exemption from United States backup withholding tax. Each Non-U.S. Bank further undertakes to deliver to each of the Company and the Administrative Agent (x) renewals or additional copies of each such form (or any successor form) on or before the date that such form expires or becomes obsolete, and (y) after the occurrence of any event requiring a change in the most recent forms so delivered by it, such additional forms or amendments thereto as may be reasonably requested by the Company or the Administrative Agent. All forms or amendments described in the preceding sentence shall certify that such Bank is entitled to receive payments under this Agreement without deduction or withholding of any United States Federal income taxes, unless an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Bank from duly completing and delivering any such form or amendment with respect to it and such Bank advises the Company and the Administrative Agent that it is not capable of receiving payments without any deduction or withholding of United States Federal income tax.

(e) For any period during which a Non-U.S. Bank has failed to provide the Company with an appropriate form pursuant to clause (d) above (unless such failure is due to a change in treaty, law or regulation, or any change in the interpretation or administration thereof by any governmental authority, occurring subsequent to the date on which a form originally was required to be provided), such Non-U.S. Bank shall not be entitled to indemnification under this Section 3.05 with respect to Taxes imposed by the United States; provided that, should a Non-U.S. Bank which is otherwise exempt from or subject to a reduced rate of withholding tax become subject to Taxes because of its failure to deliver a form required under clause (d) above, the Company shall take such steps as such Non-U.S. Bank shall reasonably request to assist such Non-U.S. Bank to recover such Taxes.

(f) Any Bank that is entitled to an exemption from or reduction of withholding tax with respect to payments under this Agreement or any Note pursuant to the law of any relevant jurisdiction or any treaty shall deliver to the Company (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate.

(g) If the IRS or any other governmental authority of the United States or any other country or any political subdivision thereof asserts a claim that the Administrative Agent did not properly withhold tax from amounts paid to or for the account of any Bank (because the appropriate form was not delivered or properly completed, because such Bank failed to notify the Administrative Agent of a change in circumstances which rendered its exemption from withholding ineffective, or for any other reason), such Bank shall indemnify the Administrative Agent fully for all amounts paid, directly or indirectly, by the Administrative Agent as tax, withholding therefor, or otherwise, including penalties and interest, and including taxes imposed by any jurisdiction on amounts payable to the Administrative Agent under this subsection, together with all costs and expenses related thereto (including attorneys fees and time charges of attorneys for the Administrative Agent, which attorneys may be employees of the Administrative Agent). The obligations of the Banks under this Section 3.05(g) shall survive the payment of the Obligations and termination of this Agreement.

3.06 Bank Statements; Survival of Indemnity. To the extent reasonably possible, each Bank shall designate an alternate Lending Installation with respect to its Eurodollar Loans to reduce any liability of the Company to such Bank under Sections 3.01, 3.02 and 3.05 or to avoid the unavailability of Eurodollar Advances under Section 3.03, so long as such designation is not, in the judgment of such Bank, disadvantageous to such Bank. Each Bank or each Issuer, as applicable, shall deliver a written statement of such Bank or such Issuer to the Company (with a copy to the Administrative Agent) as to the amount due, if any, under Section 3.01, 3.02, 3.04 or 3.05. Such written statement shall set forth in reasonable detail the calculations upon which such Bank or such Issuer determined such amount and shall be final, conclusive and binding on the Company in the absence of manifest error. Determination of amounts payable under such Sections in connection with a Eurodollar Loan shall be calculated as though each Bank funded its Eurodollar Loan through the purchase of a deposit of the type and maturity corresponding to the deposit used as a reference in determining the Eurodollar Rate applicable to such Loan, whether in fact that is the case or not. Unless otherwise provided herein, the amount specified in the written statement of any Bank or any Issuer shall be payable on demand after receipt by the Company of such written statement. The obligations of the Company under Sections 3.01, 3.02, 3.04 and 3.05 shall survive payment of the Obligations and termination of this Agreement.

5.05 Litigation; Environmental Claims. Except as set forth in the Company’s financial statements dated June 30, 2005, there are, as of the Execution Date, no actions, suits, proceedings, claims (including Environmental Claims) or disputes pending, or, to the knowledge of the Company, threatened, at law, in equity, in arbitration or by or before any Governmental Authority, against the Company, or its Subsidiaries or any of their respective properties which: (a) purport to affect or pertain to this Agreement or any other Loan Document, or any of the transactions contemplated hereby or thereby; or (b) if determined adversely to the Company or its Subsidiaries, would reasonably be expected to have a Material Adverse Effect.

(f) Neither the Company nor any ERISA Affiliate has transferred any Unfunded Pension Liability to any Person or otherwise engaged in a transaction that could be subject to Section 4069 of ERISA.

(g) Neither the Company nor any ERISA Affiliate has incurred nor reasonably expects to incur, any liability (and no event has occurred which, with the giving of notice under Section 4219 of ERISA, would result in such liability) under Section 4201 or 4243 of ERISA with respect to a Multiemployer Plan.

5.08 Use of Proceeds; Margin Regulations. The proceeds of the Loans are to be used solely for the purposes set forth in and permitted by Section 6.11 and Section 7.06.

Margin Stock constitutes less than 25% of the value of those assets of the Company and its Subsidiaries which are subject to any limitation on sale, pledge or other restriction hereunder.

5.09 Title to Properties.

There is no proposed tax assessment against the Company or any Subsidiary that would, if made, have a Material Adverse Effect.

5.11 Financial Condition. (a) The audited consolidated and consolidating financial statements of the Company and its Subsidiaries dated December 31, 2004 and the unaudited consolidated and consolidating financial statements of the Company and its Subsidiaries dated June 30, 2005, and the related consolidated and consolidating statements of income or operations, shareholders’ equity and cash flows for the fiscal periods ended on such dates:

(ii) fairly present the financial condition of the Company and its Subsidiaries as of the dates thereof and results of operations for the periods covered thereby; and

The Company conducts in the ordinary course of business a review of the effect of existing Environmental Laws and existing Environmental Claims on its business, operations and properties, and as a result thereof the Company has reasonably concluded that such Environmental Laws and Environmental Claims could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

5.13 Regulated Entities. None of the Company, any Person controlling the Company, or any Subsidiary, is required to register as an “Investment Company” within the meaning of the Investment Company Act of 1940. The Company is not subject to regulation under the Public Utility Holding Company Act of 1935, the Federal Power Act, the Interstate Commerce Act, any state public utilities code, or any other Federal or state statute or regulation limiting its ability to incur Indebtedness.

5.14 Copyrights, Patents, Trademarks and Licenses, etc. The Company or its Subsidiaries own or are licensed or otherwise have the right to use all of the patents, trademarks, service marks, trade names, copyrights, contractual franchises, authorizations and other rights that are reasonably necessary for the operation of their respective businesses, without conflict with the rights of any other Person, except to the extent that noncompliance would not have a Material Adverse Effect. To the knowledge of the Company, no slogan or other advertising device, product, process, method, substance, part or other material now employed, or now contemplated to be employed, by the Company or any Subsidiary infringes upon any rights held by any other Person, except to the extent that noncompliance would not have a Material Adverse Effect. No claim or litigation regarding any of the foregoing is pending or threatened, and no patent, invention, device, application, principle or any statute, law, rule, regulation, standard or code is pending or, to the knowledge of the Company, proposed, which, in either case, could reasonably be expected to have a Material Adverse Effect.

None of the representations or warranties made by the Company or any Subsidiary in the Loan Documents as of the date such representations and warranties are made or deemed made, and none of the statements contained in any exhibit, report, statement or certificate furnished by or on behalf of the Company or any Subsidiary in connection with the Loan Documents contains any untrue statement of a material fact or omits any material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances under which they are made, not misleading as of the time when made or delivered. It is understood that any financial projections contained in any of the aforementioned materials represent projections based on various assumptions that the Company believes in good faith are reasonable in light of the circumstances and that any such projection of future results of operations may or may not occur and no assurance can be given that any such projected results will be achieved.

5.19 Senior Debt. The Obligations shall be at least pari passu with all other senior unsecured debt of the Company.

THE ADMINISTRATIVE AGENT

(a) U.S. Bank is hereby appointed by each of the Banks as its contractual representative (herein referred to as the “Administrative Agent”) hereunder and under each other Loan Document, and each of the Banks irrevocably authorizes the Administrative Agent to act as the contractual representative of such Bank with the rights and duties expressly set forth herein and in the other Loan Documents. The Administrative Agent agrees to act as such contractual representative upon the express conditions contained in this Article IX. Notwithstanding the use of the defined term “Administrative Agent,” it is expressly understood and agreed that the Administrative Agent shall not have any fiduciary responsibilities to any Bank by reason of this Agreement or any other Loan Document and that the Administrative Agent is merely acting as the contractual representative of the Banks with only those duties as are expressly set forth in this Agreement and the other Loan Documents. In its capacity as the Banks’ contractual representative, the Administrative Agent (i) does not hereby assume any fiduciary duties to any of the Banks, (ii) is a “representative” of the Banks within the meaning of Section 9-102 of the Uniform Commercial Code and (iii) is acting as an independent contractor, the rights and duties of which are limited to those expressly set forth in this Agreement and the other Loan Documents. Each of the Banks hereby agrees to assert no claim against the Administrative Agent on any agency theory or any other theory of liability for breach of fiduciary duty, all of which claims each Bank hereby waives.

(b) Each Issuer shall act on behalf of the Banks with respect to any Letter of Credit issued by it and the documents associated therewith. Each Issuer shall have all of the benefits and immunities provided to the Administrative Agent in this Article IX with respect to any acts taken or omissions suffered by such Issuer in connection with Letters of Credit issued by it or proposed to be issued by it and the applications and agreements for letters of credit pertaining to such Letters of Credit as fully as if the term “Administrative Agent”, as used in this Article IX, included such Issuer with respect to such acts or omissions and as additionally provided in this Agreement with respect to such Issuer.

9.02 Powers. The Administrative Agent shall have and may exercise such powers under the Loan Documents as are specifically delegated to the Administrative Agent by the terms of each thereof, together with such powers as are reasonably incidental thereto. The Administrative Agent shall have no implied duties to the Banks, or any obligation to the Banks to take any action thereunder except any action specifically provided by the Loan Documents to be taken by the Administrative Agent.

9.03 General Immunity. Neither the Administrative Agent nor any of its directors, officers, agents or employees shall be liable to the Company or any Bank for any action taken or omitted to be taken by it or them hereunder or under any other Loan Document or in connection herewith or therewith except to the extent such action or inaction is determined in a final non-appealable judgment by a court of competent jurisdiction to have arisen from the gross negligence or willful misconduct of such Person.

9.04 No Responsibility for Loans, Recitals, etc. Neither the Administrative Agent nor any of its directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into, or verify (a) any statement, warranty or representation made in connection with any Loan Document or any borrowing hereunder; (b) the performance or observance of any of the covenants or agreements of any obligor under any Loan Document, including, without limitation, any agreement by an obligor to furnish information directly to each Bank; (c) the satisfaction of any condition specified in Article IV, except receipt of items required to be delivered solely to the Administrative Agent; (d) the existence or possible existence of any Default or Event of Default; (e) the validity, enforceability, effectiveness, sufficiency or genuineness of any Loan Document or any other instrument or writing furnished in connection therewith; (f) the value, sufficiency, creation, perfection or priority of any Lien in any collateral security; or (g) the financial condition of the Company or any guarantor of any of the Obligations or of any of the Company’s or any such guarantor’s respective Subsidiaries. The Administrative Agent shall have no duty to disclose to the Banks information that is not required to be furnished by the Company to the Administrative Agent at such time, but is voluntarily furnished by the Company to the Administrative Agent (either in its capacity as Administrative Agent or in its individual capacity).

9.05 Action on Instructions of Banks. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder and under any other Loan Document in accordance with written instructions signed by the Majority Banks, and such instructions and any action taken or failure to act pursuant thereto shall be binding on all of the Banks. The Banks hereby acknowledge that the Administrative Agent shall be under no duty to take any discretionary action permitted to be taken by it pursuant to the provisions of this Agreement or any other Loan Document unless it shall be requested in writing to do so by the Majority Banks. The Administrative Agent shall be fully justified in failing or refusing to take any action hereunder and under any other Loan Document unless it shall first be indemnified to its satisfaction by the Banks pro rata against any and all liability, cost and expense that it may incur by reason of taking or continuing to take any such action.

9.06 Employment of Agents and Counsel. The Administrative Agent may execute any of its duties as Administrative Agent hereunder and under any other Loan Document by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Banks, except as to money or securities received by it or its authorized agents, for the default or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care. The Administrative Agent shall be entitled to advice of counsel concerning the contractual arrangement between the Administrative Agent and the Banks and all matters pertaining to the Administrative Agent’s duties hereunder and under any other Loan Document.

9.07 Reliance on Documents; Counsel. The Administrative Agent shall be entitled to rely upon any Note, notice, consent, certificate, affidavit, letter, telegram, statement, paper or document believed by it to be genuine and correct and to have been signed or sent by the proper person or persons, and, in respect to legal matters, upon the opinion of counsel selected by the Administrative Agent, which counsel may be employees of the Administrative Agent. For purposes of determining compliance with the conditions specified in Section 4.01, each Bank that has executed this Agreement shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter either sent by the Administrative Agent to such Bank for consent, approval, acceptance or satisfaction, or required thereunder to be consented to or approved by or acceptable or satisfactory to the Bank.

9.08 Administrative Agent’s Reimbursement and Indemnification. The Banks agree to reimburse and indemnify the Administrative Agent ratably in proportion to their respective Commitments (or, if the Commitments have been terminated, in proportion to their Commitments immediately prior to such termination) (i) for any amounts not reimbursed by the Company for which the Administrative Agent is entitled to reimbursement by the Company under the Loan Documents, (ii) for any other expenses incurred by the Administrative Agent on behalf of the Banks, in connection with the preparation, execution, delivery, administration and enforcement of the Loan Documents (including, without limitation, for any expenses incurred by the Administrative Agent in connection with any dispute between the Administrative Agent and any Bank or between two or more of the Banks) and (iii) for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Administrative Agent in any way relating to or arising out of the Loan Documents or any other document delivered in connection therewith or the transactions contemplated thereby (including, without limitation, for any such amounts incurred by or asserted against the Administrative Agent in connection with any dispute between the Administrative Agent and any Bank or between two or more of the Banks), or the enforcement of any of the terms of the Loan Documents or of any such other documents; provided that (i) no Bank shall be liable for any of the foregoing to the extent any of the foregoing is found in a final non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Administrative Agent and (ii) any indemnification required pursuant to Section 3.05(g) shall, notwithstanding the provisions of this Section 9.08, be paid by the relevant Bank in accordance with the provisions thereof. The obligations of the Banks under this Section 9.08 shall survive payment of the Obligations and termination of this Agreement.

9.09 Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder, except with respect to a Default or Event of Default arising from the non-payment of principal, interest or fees required to be paid to the Administrative Agent for the account of the Banks, unless the Administrative Agent has received written notice from a Bank or the Company referring to this Agreement describing such Default or Event of Default and stating that such notice is a “notice of default”. If the Administrative Agent receives such a notice, the Administrative Agent shall give prompt notice thereof to the Banks.

9.10 Rights as a Bank. If the Administrative Agent is a Bank, the Administrative Agent shall have the same rights and powers hereunder and under any other Loan Document with respect to its Commitment and its Loans as any Bank and may exercise the same as though it were not the Administrative Agent, and the term “Bank” or “Banks” shall, at any time when the Administrative Agent is a Bank, unless the context otherwise indicates, include the Administrative Agent in its individual capacity. The Administrative Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of trust, debt, equity or other transaction, in addition to those contemplated by this Agreement or any other Loan Document, with the Company or any of its Affiliates in which the Company or such Affiliates is not restricted hereby from engaging with any other Person. The Administrative Agent, in its individual capacity, is not obligated to remain a Bank.

9.11 Bank Credit Decision. Each Bank acknowledges that it has, independently and without reliance upon the Administrative Agent, any Co-Lead Arranger, any Issuer or any other Bank and based on the financial statements prepared by the Company and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the other Loan Documents. Each Bank also acknowledges that it will, independently and without reliance upon the Administrative Agent, any Co-Lead Arranger, any Issuer or any other Bank and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Loan Documents.

9.12 Successor Administrative Agent. The Administrative Agent may resign at any time by giving written notice thereof to the Banks and the Company, such resignation to be effective upon the appointment of a successor Administrative Agent or, if no successor Administrative Agent has been appointed, 45 days after the retiring Administrative Agent gives notice of its intention to resign. The Administrative Agent may be removed at any time with or without cause by written notice received by the Administrative Agent from the Majority Banks, such removal to be effective on the date specified by the Majority Banks; provided that the Administrative Agent may not be removed unless the Administrative Agent (in its individual capacity) and any affiliate thereof acting as Issuer is relieved of all of its duties as Issuer pursuant to documentation reasonably satisfactory to such Person on or prior to the date of such removal. Upon any such resignation or removal, the Majority Banks shall have the right to appoint, on behalf of the Company and the Banks, a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Majority Banks within thirty days after the resigning Administrative Agent’s giving notice of its intention to resign, then the resigning Administrative Agent may appoint, on behalf of the Company and the Banks, a successor Administrative Agent. Notwithstanding the previous sentence, the Administrative Agent may at any time without the consent of the Company or any Bank, appoint any of its Affiliates which is a commercial bank as a successor Administrative Agent hereunder. If the Administrative Agent has resigned or been removed and no successor Administrative Agent has been appointed, the Banks may perform all the duties of the Administrative Agent hereunder and the Company shall make all payments in respect of the Obligations to the applicable Bank and for all other purposes shall deal directly with the Banks. No successor Administrative Agent shall be deemed to be appointed hereunder until such successor Administrative Agent has accepted the appointment. Any such successor Administrative Agent shall be a commercial bank having capital and retained earnings of at least $100,000,000. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the resigning or removed Administrative Agent. Upon the effectiveness of the resignation or removal of the Administrative Agent, the resigning or removed Administrative Agent shall be discharged from its duties and obligations hereunder and under the Loan Documents. After the effectiveness of the resignation or removal of an Administrative Agent, the provisions of this Article IX shall continue in effect for the benefit of such Administrative Agent in respect of any actions taken or omitted to be taken by it while it was acting as the Administrative Agent hereunder and under the other Loan Documents. If there is a successor to the Administrative Agent by merger, or the Administrative Agent assigns its duties and obligations to an Affiliate pursuant to this Section 9.12, then the term “Prime Rate” as used in this Agreement shall mean the prime rate, base rate or other analogous rate of the new Administrative Agent.

9.13 Administrative Agent’s and Co-Lead Arrangers’ Fees. The Company agrees to pay to the Administrative Agent and to the Co-Lead Arrangers, for their respective accounts, the fees agreed to by the Company, the Administrative Agent and the Co-Lead Arrangers pursuant to the letter agreement dated August 26, 2005, or as otherwise agreed from time to time.

9.14 Delegation to Affiliates. The Company and the Banks agree that the Administrative Agent may delegate any of its duties under this Agreement to any of its Affiliates. Any such Affiliate (and such Affiliate’s directors, officers, agents and employees) which performs duties in connection with this Agreement shall be entitled to the same benefits of the indemnification, waiver and other protective provisions to which the Administrative Agent is entitled under Articles VIII and IX.

9.15 Other Agents. No Co-Syndication Agent or Co-Documentation Agent shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Banks as such. Without limiting the foregoing, no Co-Syndication Agent or Co-Documentation Agent shall have or be deemed to have a fiduciary relationship with any Bank. Each Bank hereby makes the same acknowledgments with respect to each Co-Syndication Agent and Co-Documentation Agent as it makes with respect to the Administrative Agent in Section 9.11.

10.05 Expenses; Indemnification. (i) The Company shall reimburse the Administrative Agent and the Co-Lead Arrangers for any reasonable costs, internal charges and out-of-pocket expenses (including attorneys’ fees and time charges of attorneys for the Administrative Agent, which attorneys may be employees of the Administrative Agent) paid or incurred by the Administrative Agent or the Co-Lead Arrangers in connection with the preparation, negotiation, execution, delivery, syndication, distribution (including, without limitation, via the internet), review, amendment, modification, and administration of the Loan Documents. The Company also agrees to reimburse the Administrative Agent, each Co-Lead Arranger, each Issuer and each Bank for any costs, internal charges and out-of-pocket expenses (including attorneys’ fees and time charges of attorneys for the Administrative Agent, such Co-Lead Arranger or such Bank) paid or incurred by the Administrative Agent, such Co-Lead Arranger, such Issuer or such Bank in connection with the collection and enforcement of the Loan Documents.

None of the Administrative Agent, the Banks or the Issuers shall be under any obligation to xxxxxxxx any assets in favor of the Company or any other Person or against or in payment of any or all of the Obligations.

The parties to this Agreement acknowledge that clause (ii) of this Section 10.07 relates only to absolute assignments and does not prohibit assignments creating security interests, including, without limitation, (x) any pledge or assignment by any Bank of all or any portion of its rights under this Agreement and any Note to a Federal Reserve Bank or (y) in the case of a Bank which is a fund, any pledge or assignment of all or any portion of its rights under this Agreement and any Note to its trustee in support of its obligations to its trustee; provided that no such pledge or assignment creating a security interest shall release the transferor Bank from its obligations hereunder unless and until the parties thereto have complied with the provisions of Section 10.08. The Administrative Agent may treat the Person which made any Loan or which holds any Note as the owner thereof for all purposes hereof unless and until such Person complies with Section 10.08; provided that the Administrative Agent may in its discretion (but shall not be required to) follow instructions from the Person which made any Loan or which holds any Note to direct payments relating to such Loan or Note to another Person. Any assignee of the rights to any Loan or any Note agrees by acceptance of such assignment to be bound by all the terms and provisions of the Loan Documents. Any request, authority or consent of any Person, who at the time of making such request or giving such authority or consent is the owner of the rights to any Loan (whether or not a Note has been issued in evidence thereof), shall be conclusive and binding on any subsequent holder or assignee of the rights to such Loan.

10.08 Participations; Assignments, etc. (a) Permitted Participants; Effect. Any Bank may, in the ordinary course of its business and in accordance with applicable law, at any time sell to one or more banks or other entities (“Participants”) participating interests in any Loan owing to such Bank, any Note held by such Bank, any Commitment of such Bank or any other interest of such Bank under the Loan Documents. Upon any such sale by a Bank of participating interests to a Participant, such Bank’s obligations under the Loan Documents shall remain unchanged, such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations, such Bank shall remain the owner of its Loans and the holder of any Note issued to it in evidence thereof for all purposes under the Loan Documents, all amounts payable by the Company under this Agreement shall be determined as if such Bank had not sold such participating interests, and the Company and the Administrative Agent shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under the Loan Documents.

(b) Voting Rights. Each Bank shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Loan Documents other than any amendment, modification or waiver which requires the unanimous consent of all Banks under Section 10.01.

(c) Benefit of Setoff. The Company agrees that each Participant shall be deemed to have the right of setoff provided in Section 10.10 in respect of its participating interest in amounts owing under the Loan Documents to the same extent as if the amount of its participating interest were owing directly to it as a Bank under the Loan Documents; provided that each Bank shall retain the right of setoff provided in Section 10.10 with respect to the amount of participating interests sold to each Participant. The Banks agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 10.10, agrees to share with each Bank, any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in accordance with Section 10.10 as if each Participant were a Bank.

(d) Permitted Assignments. Any Bank may, in the ordinary course of its business and in accordance with applicable law, at any time assign to one or more Eligible Assignees (“Purchasers”) all or any part of its rights and obligations under the Loan Documents. Any assignment shall be made pursuant to a document substantially in the form of Exhibit F or in such other form as may be agreed to by the parties thereto. The consent of the Company and the Administrative Agent shall be required prior to an assignment becoming effective with respect to a Purchaser which is not a Bank or an Affiliate thereof; provided that if a Default or an Event of Default has occurred and is continuing, the consent of the Company shall not be required. Such consent shall not be unreasonably withheld or delayed. Each such assignment with respect to a Purchaser which is not a Bank or an Affiliate thereof shall (unless each of the Company and the Administrative Agent otherwise consents) be in an amount not less than the lesser of (i) $5,000,000 or (ii) the remaining amount of the assigning Bank’s Commitment (calculated as at the date of such assignment) or outstanding Loans (if such Commitment has been terminated).

(e) Effect; Effective Date. Upon (i) delivery to the Administrative Agent of a notice of assignment, substantially in the form attached as Annex I to Exhibit F (a “Notice of Assignment”), together with any consents required by Section 10.08(d), and (ii) payment of a $4,000 fee to the Administrative Agent for processing such assignment, such assignment shall become effective on the effective date specified in such Notice of Assignment. The Notice of Assignment shall contain a representation by the Purchaser to the effect that none of the consideration used to make the purchase of the Commitment and Loans under the applicable assignment agreement constitutes “plan assets” as defined under ERISA and that the rights and interests of the Purchaser in and under the Loan Documents will not be “plan assets” under ERISA. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Bank party to this Agreement and any other Loan Document executed by or on behalf of the Banks and shall have all the rights and obligations of a Bank under the Loan Documents, to the same extent as if it were an original party hereto, and no further consent or action by the Company, the Banks or the Administrative Agent shall be required to release the transferor Bank with respect to the percentage of the Aggregate Commitment and Loans assigned to such Purchaser. Upon the consummation of any assignment to a Purchaser pursuant to this Section 10.08(e), the transferor Bank, the Administrative Agent and the Company shall, if the transferor Bank or the Purchaser desires that its Loans be evidenced by Notes, make appropriate arrangements so that new Notes or, as appropriate, replacement Notes are issued to such transferor Bank and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser, in each case in principal amounts reflecting their respective Commitments, as adjusted pursuant to such assignment.

(f) Dissemination of Information. The Company authorizes each Bank to disclose to any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (each a “Transferee”) and any prospective Transferee any and all information in such Bank’s possession concerning the creditworthiness of the Company and its Subsidiaries; provided that each Transferee and prospective Transferee agrees to be bound by Section 10.09 of this Agreement.

(g) Tax Treatment. If any interest in any Loan Document is transferred to any Transferee which is organized under the laws of any jurisdiction other than the United States or any State thereof, the transferor Bank shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 3.05(d).

10.09 Confidentiality. Each Bank agrees to take and to cause its Affiliates to take normal and reasonable precautions and exercise due care to maintain the confidentiality of all information identified as “confidential” or “secret” by the Company and provided to it by the Company or any Subsidiary, or by the Administrative Agent on the Company’s or such Subsidiary’s behalf, under this Agreement or any other Loan Document, and neither it nor any of its Affiliates shall use any such information other than in connection with or in enforcement of this Agreement and the other Loan Documents or in connection with other business now or hereafter existing or contemplated with the Company or any Subsidiary; except to the extent such information (i) was or becomes generally available to the public other than as a result of disclosure by the Bank, or (ii) was or becomes available on a non-confidential basis from a source other than the Company, provided that such source is not bound by a confidentiality agreement with the Company known to the Bank; provided that any Bank may disclose such information (A) at the request or pursuant to any requirement of any Governmental Authority to which the Bank is subject or in connection with an examination of such Bank by any such authority; (B) pursuant to subpoena or other court process; (C) when required to do so in accordance with the provisions of any applicable Requirement of Law; (D) to the extent reasonably required in connection with any litigation or proceeding to which the Administrative Agent, any Bank or their respective Affiliates may be party; (E) to the extent reasonably required in connection with the exercise of any remedy hereunder or under any other Loan Document; (F) to such Bank’s independent auditors and other professional advisors; (G) to any Participant or Assignee, actual or potential, provided that such Person agrees in writing to keep such information confidential to the same extent required of the Banks hereunder; (H) as to any Bank or its Affiliate, as expressly permitted under the terms of any other document or agreement regarding confidentiality to which the Company or any Subsidiary is party or is deemed party with such Bank or such Affiliate; and (I) to its Affiliates. Notwithstanding anything herein to the contrary, the Administrative Agent, each Issuer and each Bank may disclose to any Person, without limitation of any kind, the U.S. tax treatment and tax structure of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analyses) that are provided to the Administrative Agent, any Issuer or any Bank relating to such U.S. tax treatment and tax structure.

10.10 Set-off; Ratable Payments. In addition to, and without limitation of, any rights of the Banks under applicable law, if any Event of Default occurs and is continuing, any and all deposits (including all account balances, whether provisional or final and whether or not collected or available) and any other Indebtedness at any time held or owing by any Bank or any Affiliate of any Bank to or for the credit or account of the Company may be offset and applied toward the payment of the Obligations owing to such Bank, whether or not the Obligations, or any part hereof, shall then be due. If any Bank, whether by setoff or otherwise, has payment made to it upon its Loans or its participations in Letters of Credit (other than payments received pursuant to Section 3.01, 3.02, 3.04 or 3.05 and payments made to any Issuer in respect of Reimbursement Obligations so long as the Banks have not funded their participations therein) in a greater proportion than that received by any other Bank, such Bank agrees, promptly upon demand, to purchase a portion of the Outstanding Credit Exposures held by the other Banks so that after such purchase each Bank will hold its Pro Rata Share of the Aggregate Outstanding Credit Exposure. If any Bank, whether in connection with setoff or amounts which might be subject to setoff or otherwise, receives collateral or other protection for its Obligations or such amounts which may be subject to setoff, such Bank agrees, promptly upon demand, to take such action necessary such that all Banks share in the benefits of such collateral ratably in accordance with their respective Pro Rata Shares. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made.

10.11 Automatic Debits of Fees. With respect to any facility fee, utilization fee, agency fee, arrangement fee, or other fee, or any other cost or expense (including Attorney Costs) due and payable to the Administrative Agent, U.S. Bank or any Co-Lead Arranger under the Loan Documents, the Company hereby irrevocably authorizes the Administrative Agent and/or U.S. Bank to debit any deposit account of the Company with Administrative Agent and/or U.S. Bank in an amount such that the aggregate amount debited from all such deposit accounts does not exceed such fee or other reasonable cost or expense. If there are insufficient funds in such deposit accounts to cover the amount of the fee or other cost or expense then due, such debits will be reversed (in whole or in part, in the Administrative Agent’s and/or U.S. Bank’s sole discretion) and such amount not debited shall be deemed to be unpaid. No such debit under this Section shall be deemed a set-off.

10.12 Notification of Addresses, Lending Installations, Etc. Each Bank shall notify the Administrative Agent in writing of any changes in the address to which notices to the Bank should be directed, of addresses of any Lending Installation, of payment instructions in respect of all payments to be made to it hereunder and of such other administrative information as the Administrative Agent shall reasonably request.

10.13 Counterparts. This Agreement may be executed in any number of separate counterparts, each of which, when so executed, shall be deemed an original, and all of such counterparts taken together shall be deemed to constitute but one and the same instrument.

10.14 Severability. The illegality or unenforceability of any provision of this Agreement or any instrument or agreement required hereunder shall not in any way affect or impair the legality or enforceability of the remaining provisions of this Agreement or any instrument or agreement required hereunder.

10.15 GOVERNING LAW AND JURISDICTION. (A) THE LOAN DOCUMENTS (OTHER THAN THOSE CONTAINING A CONTRARY EXPRESS CHOICE OF LAW PROVISION) SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAW OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW (OTHER THAN TITLE 14 OF ARTICLE 5 OF THE NEW YORK GENERAL OBLIGATIONS LAW); PROVIDED THAT THE ADMINISTRATIVE AGENT AND THE BANKS SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

(B) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF NEW YORK, AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH OF THE COMPANY, THE ADMINISTRATIVE AGENT, EACH ISSUER AND EACH BANK CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE COURTS. EACH OF THE COMPANY, THE ADMINISTRATIVE AGENT, EACH ISSUER AND EACH BANK IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF THIS AGREEMENT OR ANY DOCUMENT RELATED HERETO. THE COMPANY, THE ADMINISTRATIVE AGENT, EACH ISSUER AND THE BANKS EACH WAIVE PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS PERMITTED BY NEW YORK LAW.

(C) NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE ADMINISTRATIVE AGENT, ANY ISSUER OR ANY BANK TO BRING PROCEEDINGS AGAINST THE COMPANY IN THE COURTS OF ANY OTHER JURISDICTION. ANY JUDICIAL PROCEEDING BY THE COMPANY AGAINST THE ADMINISTRATIVE AGENT, ANY ISSUER OR ANY BANK OR ANY AFFILIATE OF THE ADMINISTRATIVE AGENT, ANY ISSUER OR ANY BANK INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT SHALL BE BROUGHT ONLY IN A COURT IN NEW YORK, NEW YORK.

10.16 WAIVER OF JURY TRIAL. THE COMPANY, THE BANKS, THE ISSUERS AND THE ADMINISTRATIVE AGENT EACH WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF OR RELATED TO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS, OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, IN ANY ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY OF THE PARTIES AGAINST ANY OTHER PARTY OR ANY AGENT-RELATED PERSON, PARTICIPANT OR ASSIGNEE, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS, OR OTHERWISE. THE COMPANY, THE BANKS, THE ISSUERS AND THE ADMINISTRATIVE AGENT EACH AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS OR ANY PROVISION HEREOF OR THEREOF. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

10.17 Entire Agreement. This Agreement, together with the other Loan Documents, embodies the entire agreement and understanding among the Company, the Banks, the Issuers and the Administrative Agent, and supersedes all prior or contemporaneous agreements and understandings of such Persons, verbal or written, relating to the subject matter hereof and thereof (other than the Fee Letter).

10.18 Survival of Representations. All representations and warranties of the Company contained in this Agreement shall survive the making of the Credit Extensions herein contemplated.

10.19 Governmental Regulation. Anything contained in this Agreement to the contrary notwithstanding, no Bank shall be obligated to extend credit to the Company in violation of any limitation or prohibition provided by any applicable statute or regulation.

10.20 Numbers of Documents. All statements, notices, closing documents, and requests hereunder shall be furnished to the Administrative Agent with sufficient counterparts so that the Administrative Agent may furnish one to each of the Banks.

10.21 Nonliability of Banks.
