Each such notice shall be effective upon receipt by the Agent, shall be in writing or by telephone or telecopy transmission, shall specify the date and amount of such LIBO Rate Funding and the Interest Period therefor. The Interest Period applicable to each LIBO Rate Funding shall begin on a Business Day, and the amount of each LIBO Rate Funding shall be an integral multiple of $1,000,000 and not less than $25,000,000. Subject to the terms and conditions hereof, the principal amount specified by the Borrower in the applicable request for a LIBO Rate Funding shall bear interest from and including the first day of the Interest Period specified therein to but not including the last day of such Interest Period, at the LIBO Rate applicable thereto, determined as set forth herein, (subject to fluctuations in the applicable Margin). Unless the Borrower requests a new LIBO Rate Funding in accordance with the procedures set forth above, or prepays the principal of an outstanding LIBO Rate Funding at the expiration of an Interest Period, the Lenders shall automatically and without request of the Borrower convert each LIBO Rate Funding to a Floating Rate Funding on the last day of the relevant Interest Period.

(c) Setting of LIBO Rates. The applicable LIBO Rate for each Interest Period shall be determined by the Agent between the opening of business and 12:00 noon on the second Business Day prior to the beginning of such Interest Period, whereupon notice thereof (which may be by telephone) shall be given by the Agent to the Borrower and each Lender. Each such determination of the applicable LIBO Rate shall be conclusive and binding upon the parties hereto, in the absence of demonstrable error. The Agent, upon written request of the Borrower, shall deliver to the Borrower a statement showing the computations used by the Agent in determining the applicable LIBO Rate hereunder.

(d) Limitations on LIBO Rate Fundings. In no event shall more than 7 LIBO Rate Fundings be outstanding at any one time. In no event may the Borrower request a LIBO Rate Funding if, after giving effect to such LIBO Rate Funding, the Borrower would be required to prepay a LIBO Rate Funding in order to make any regularly scheduled principal payment.

Section 2.4 Principal and Interest Payment Dates.

(a) Interest. Interest accruing on Floating Rate Fundings shall be due and payable on the last day of each calendar quarter. Interest on any LIBO Rate Funding shall be due and payable on the last day of the applicable Interest Period or, if such Interest Period is in excess of three months, on the last day of each three-month period during such Interest Period and on the last day of such Interest Period.

(b) Principal. The Borrower shall pay the principal balance of the Notes in full on the Maturity Date.

Section 2.5 Level Status, Margins and Fee Rates.

(a) The Borrower’s Level Status shall be determined on the basis of the Applicable Ratings established by the Rating Agencies, in accordance with the following table:

	Level I	Level II	Level III	Level IV	Level V
S&P	A or better	A- or better, but less than A	BBB+ or better, but less than A-	BBB or better, but less than BBB+	Less than BBB
Moody’s	A2 or better	A3 or better, but less than A2	Baa1 or better, but less than A3	Baa2 or better, but less than Baa1	Less than Baa2
Fitch	A or better	A- or better, but less than A	BBB+ or better, but less than A-	BBB or better, but less than BBB+	Less than BBB

If the Applicable Ratings established by the Rating Agencies differ such that they do not fall within a single column in the table set forth above, the Borrower’s Level Status shall be determined as follows:

(i) If the Applicable Ratings applied by any two of the Rating Agencies are in the same column, the Borrower’s Level Status shall be determined by that column.

(ii) If the Applicable Ratings are each in separate columns, the highest and lowest columns shall be excluded, and the Borrower’s Level Status shall be determined by the remaining Applicable Rating.

(b) In making the determinations under paragraph (a):

(i) If any of the Rating Agencies changes the meaning or designation for its Applicable Ratings referenced in paragraph (a), the criteria for Level Status in the table in paragraph (a) shall be adjusted in such manner as the Required Lenders may reasonably determine to correspond with the applicable rating designations used by the applicable Rating Agency in effect on the date hereof.

(ii) If one of the Rating Agencies ceases to rate the Borrower’s long-term unsecured debt such that only two of the Rating Agencies are providing such Applicable Ratings, the Borrower’s Level Status shall be determined as follows:

(A) If the Applicable Ratings provided by both of the remaining Rating Agencies are in the same column, the Borrower’s Level Status shall be determined by that column.

(B) If the Applicable Ratings provided by the remaining Rating Agencies are in adjacent columns, the Borrower’s Level Status shall be based on the leftmost of the columns.

(C) If the Applicable Ratings provided by the remaining Rating Agencies are separated by one or more columns, the Borrower’s Level Status shall be based on the column to the immediate right of the leftmost applicable column.

Notwithstanding the foregoing, if the Applicable Rating established by either of the remaining Rating Agencies is in the rightmost column above, the Borrower shall be deemed to be at Level Status V.

(iii) If any two of the Rating Agencies ceases to establish its Applicable Rating, the Borrower shall be deemed to be at Level Status V.

(c) The Floating Rate Margin, LIBO Rate Margin and Facility Fee Rate at any time shall be determined from time to time on the basis of the Borrower’s Level Status, in accordance with the following table:

	Xxxxx X	Xxxxx XX	Xxxxx XXX	Xxxxx XX	Level V
Floating Rate Margin	0%	0%	0%	0%	0%
LIBO Rate Margin	0.200%	0.240%	0.305%	0.410%	0.600%
Facility Fee Rate	0.050%	0.060%	0.070%	0.090%	0.150%

(d) Upon the occurrence of any Default or Event of Default, and so long as such Default or Event of Default continues without written waiver thereof by the Lenders, a default increment equal to 200 basis points (2.00%) shall be added to the Floating Rate Margin and LIBO Rate Margin. Inclusion of such default increment shall not be deemed a waiver or excuse of any such Default or Event of Default.

Section 2.6 Fees.

(a) Facility Fee. The Borrower shall pay to the Agent, for the ratable benefit of the Lenders, a facility fee determined at an annual rate equal to the then-applicable Facility Fee Rate applied to the average aggregate Credit Exposure during such calendar quarter (or during such shorter period ending on the Maturity Date). The facility fee shall be due and payable quarterly in arrears on the last day of each calendar quarter, and on the Maturity Date. The facility fee shall accrue at all times, including at any time during which any condition in Article III has not been satisfied.

(b) Fee Letters. The Borrower shall pay to the Agent all fees required to be paid pursuant to any Fee Letters.

(c) Audit Fees. Upon the occurrence of an Event of Default or at any time thereafter until such Event of Default is cured, the Borrower shall pay to the Agent, on written demand, reasonable fees charged by the Agent in connection with any audits or inspections by the Agent of any collateral or the operations or businesses of the Borrower, together with actual out-of-pocket costs and expenses incurred in conducting any such audit or inspection. All such audits and inspections shall be for the sole benefit of the Agent and the Lenders.

Section 2.7 Prepayments.

(a) Voluntary Prepayments. The Borrower from time to time may voluntarily prepay the Notes in whole or in part; provided that (i) prepayment of any Lender’s Note must be accompanied by pro rata prepayment of each other Lender’s Note, (ii) any prepayment of the full amount of any Note shall include accrued interest thereon, (iii) partial prepayment of any Floating Rate Funding shall be in an aggregate amount not less than $1,000,000, (iv) partial prepayment of any LIBO Rate Funding shall be in an aggregate amount not less than $5,000,000, and (v) any prepayment of any LIBO Rate Funding shall be made only upon three Business Days’ notice to the Agent.

(b) Mandatory Prepayment.

(i) Promptly following the receipt by the Borrower or any Subsidiary of proceeds from the sale by Centennial Energy Resources LLC or any other Subsidiary of the Capital Stock or assets of Centennial Power, Inc. or Colorado Energy Management, LLC, the Borrower shall prepay the Obligations in an amount equal to such proceeds; provided, however, that the aggregate amount required to be prepaid under this paragraph (i) shall not exceed the lesser of (A) $220,000,000, or (B) the then-outstanding Obligations.

(ii) Promptly following the receipt thereof, the Borrower shall prepay the Obligations in an amount equal to 100% of the net proceeds realized by the Borrower or Cascade DebtCo from (A) debt obligations incurred by the Borrower or Cascade DebtCo after the date hereof (other than hereunder), or (B) the issuance by the Borrower or Cascade DebtCo of Capital Stock; provided, however, that the aggregate amount required to be paid under this paragraph (ii) shall not exceed the then-outstanding Obligations.

(c) Application of Prepayments. So long as no Default or Event of Default has occurred and is continuing hereunder, all prepayments hereunder shall be applied in such order of application as the Borrower may direct in writing. In all other cases, all prepayments hereunder shall be applied in the following order:

(i) First, to the principal balance of the Notes.

(ii) Second, to accrued but unpaid interest on the Notes.

(iii) Third, to any remaining Obligations, in such order as the Agent may in its sole discretion designate.

Notwithstanding the foregoing, interest on any LIBO Rate Funding prepaid hereunder and any compensation due under Section 2.10 on account of prepayment of a LIBO Rate Funding shall be paid with the same priority as the related principal prepayment.

Section 2.8 Payments.

(a) Making of Payments. All payments of principal of and interest due under the Notes shall be made to the Agent at its principal office in Minneapolis, Minnesota, not later than 12:00 noon on the date due, in immediately available funds, and funds received after that hour shall be deemed to have been received by the Agent on the next following Business Day. The Borrower hereby authorizes the Agent to charge the Borrower’s demand deposit account maintained with the Agent for the amount of any such payment on its due date, all without receipt of any request for such charge, but the Lender’s failure to so charge such account shall in no way affect the obligation of the Borrower to make any such payment.

(b) Assumed Payments. Unless the Agent has been notified by a Lender or the Borrower prior to the date on which such Lender or the Borrower is scheduled to make payment to the Agent of (in the case of a Lender) its Percentage of the Term Loan or (in the case of the Borrower) a payment to the Agent for the account of one or more of the Lenders hereunder (such payment by a Lender or the Borrower (as the case may be) being herein called a “Required Payment”), which notice shall be effective upon receipt, that it does not intend to make the Required Payment to the Agent, the Agent may assume that the Required Payment has been made and may (but shall not be required to), in reliance upon such assumption, make the amount thereof available to the intended recipient on such date and, if such Lender or the Borrower (as the case may be) has not in fact made the Required Payment to the Agent, the recipient of such payment shall, on demand, repay to the Agent the amount so made available together with interest thereon for each day during the period commencing on the date such amount was so made available by the Agent until the date the Agent recovers such amount at a rate (i) equal to the Federal Funds Rate for such day, in the case of a Required Payment owing by a Lender, or (ii) equal to the applicable rate of interest as provided in this Agreement, in the case of a Required Payment owing by the Borrower.

(c) Setoff. The Borrower agrees that each Lender shall have all rights of setoff and bankers’ lien provided by applicable law, and in addition thereto, the Borrower agrees that if at any time any amount is due and owing by the Borrower under this Agreement to any Lender at a time when an Event of Default has occurred and is continuing hereunder, any Lender may apply any and all balances, credits, and deposits, accounts or moneys of the Borrower then or thereafter in the possession of that Lender (excluding, however, any trust or escrow accounts held by the Borrower for the benefit of any third party) to the payment thereof.

(d) Due Date Extension. If any payment of principal of or interest on any Floating Rate Funding or any fees payable hereunder falls due on a day which is not a Business Day, then such due date shall be extended to the next following Business Day, and (in the case of principal) additional interest shall accrue and be payable for the period of such extension.

(e) Application of Payments. Except as otherwise provided herein, so long as no Default or Event of Default has occurred and is continuing hereunder, each payment received from the Borrower shall be applied to such obligation as the Borrower shall specify by notice received by the Agent on or before the date of such payment, or in the absence of such notice, as the Required Lenders shall determine in their discretion. Except as otherwise provided herein, after the occurrence of a Default or Event of Default, the Lenders shall have the right to apply all payments received by the Lender from the Borrower as the Required Lenders may determine in their discretion. The Borrower agrees that the amount shown on the books and records of the Agent and the Lenders as being the principal balance of and interest on the Notes shall be conclusive absent demonstrable error.

Section 2.9 Increased Costs; Funding Exceptions.

(a) Increased Costs on LIBO Rate Fundings. If Regulation D of the Board of Governors of the Federal Reserve System or after the date of this Agreement the adoption of any applicable law, rule or regulation, or any change in any existing law, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency, shall:

(i) subject that Lender to or cause the withdrawal or termination of any exemption previously granted to that Lender with respect to, any tax, duty or other charge with respect to its LIBO Rate Fundings or its obligation to make LIBO Rate Fundings, or shall change the basis of taxation of payments to that Lender of the principal of or interest under this Agreement in respect of its LIBO Rate Fundings or its obligation to make LIBO Rate Fundings (except for changes in the rate of tax on the overall net income of that Lender imposed by the jurisdictions in which that Lender’s principal executive office is located); or

(ii) impose, modify or deem applicable any reserve (including, without limitation, any reserve imposed by the Board of Governors of the Federal Reserve System, but excluding any reserve included in the determination of interest rates pursuant to Section 2.3), special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, that Lender; or

(iii) impose on that Lender any other condition affecting its making, maintaining or funding of its LIBO Rate Fundings or its obligation to make LIBO Rate Fundings;

and the result of any of the foregoing is to increase the cost to that Lender of making or maintaining any LIBO Rate Funding, or to reduce the amount of any sum received or receivable by that Lender under this Agreement or under its Notes with respect to a LIBO Rate Funding, then that Lender will notify the Borrower of such increased cost and within fifteen (15) days after demand by that Lender (which demand shall be accompanied by a statement setting forth the basis of such demand and representing that that Lender has made similar demand on one or more other commercial borrowers with revolving or term loans in excess of $1,000,000) the Borrower shall pay to that Lender such additional amount or amounts as will compensate that Lender for such increased cost or such reduction; provided, however, that no such increased cost or such reduction shall be payable by the Borrower for any period longer than ninety (90) days prior to the date on which notice thereof is delivered to the Borrower. Each Lender will promptly notify the Borrower of any event of which it has knowledge, occurring after the date hereof, which will entitle that Lender to compensation pursuant to this Section 2.9. If the Borrower receives notice from any Lender of any event which will entitle that Lender to compensation pursuant to this Section 2.9, the Borrower may prepay any then outstanding LIBO Rate Fundings or notify that Lender that any pending request for a LIBO Rate Funding shall be deemed to be a request for a Floating Rate Funding, in each case subject to the provisions of Section 2.10.

(b) Basis for Determining Interest Rate Inadequate or Unfair. If with respect to any Interest Period:

(i) any Lender determines that deposits in U.S. dollars (in the applicable amounts) are not being offered in the London interbank eurodollar market for such Interest Period; or

(ii) any Lender otherwise determines that by reason of circumstances affecting the London interbank eurodollar market adequate and reasonable means do not exist for ascertaining the applicable LIBO Rate; or

(iii) any Lender determines that the LIBO Rate as determined by the Agent will not adequately and fairly reflect the cost to that Lender of maintaining or funding a LIBO Rate Funding for such Interest Period, or that the making or funding of LIBO Rate Fundings has become impracticable as a result of an event occurring after the date of this Agreement which in the opinion of that Lender materially affects such LIBO Rate Fundings;

then that Lender shall promptly notify the Borrower and (A) upon the occurrence of any event described in the foregoing clause (i) the Borrower shall enter into good faith negotiations with that Lender in order to determine an alternate method to determine the LIBO Rate for that Lender, and during the pendency of such negotiations with that Lender, the Lenders shall be under no obligation to make any new LIBO Rate Fundings, and (B) upon the occurrence of any event described in the foregoing clauses (ii) or (iii), for so long as such circumstances shall continue, the Lenders shall be under no obligation to make any new LIBO Rate Fundings.

(c) Illegality. If any change in (including the adoption of any new) applicable laws or regulations, or any change in the interpretation of applicable laws or regulations by any governmental authority, central bank, comparable agency or any other regulatory body charged with the interpretation, implementation or administration thereof, or compliance by any Lender with any request or directive (whether or not having the force of law) of any such authority, central bank, comparable agency or other regulatory body, should make it or, in the good faith judgment of that Lender, shall raise a substantial question as to whether it is unlawful for that Lender to make, maintain or fund LIBO Rate Fundings, then (i) that Lender shall promptly notify the Borrower and the Agent, (ii) the obligation of the Lenders to make, maintain or convert into LIBO Rate Fundings shall, upon the effectiveness of such event, be suspended for the duration of such unlawfulness, and (iii) for the duration of such unlawfulness, any notice by the Borrower requesting the Lenders to make or convert into LIBO Rate Fundings shall be construed as a request to make or to continue making Floating Rate Fundings.

Section 2.10 Funding Losses.

Upon demand by any Lender (which demand shall be accompanied by a statement setting forth the basis for the calculations of the amount being claimed), the Borrower shall indemnify that Lender against any loss or expense which that Lender may have sustained or incurred (including, without limitation, any net loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by that Lender to fund or maintain LIBO Rate Fundings) or which that Lender may be deemed to have sustained or incurred, as reasonably determined by that Lender, (i) as a consequence of any failure by the Borrower to make any payment when due of any amount due hereunder in connection with any LIBO Rate Fundings, (ii) due to any failure of the Borrower to borrow or convert any LIBO Rate Fundings on a date specified therefor in a notice thereof or (iii) due to any payment or prepayment of any LIBO Rate Funding on a date other than the last day of the applicable Interest Period for such LIBO Rate Funding. For this purpose, all notices under Section 2.3(b) shall be deemed to be irrevocable.

Section 2.11 Discretion of Lenders as to Manner of Funding.

Notwithstanding any provision of this Agreement to the contrary, each Lender shall be entitled to fund and maintain all or any part of its LIBO Rate Fundings in any manner it deems fit, it being understood, however, that for the purposes of this Agreement (specifically including, without limitation, Section 2.10 hereof) all determinations hereunder shall be made as if that Lender had actually funded and maintained each LIBO Rate Funding during each Interest Period for such LIBO Rate Funding through the purchase of deposits having a maturity corresponding to such Interest Period and bearing an interest rate equal to the appropriate LIBO Rate for such Interest Period.

Section 2.12 Conclusiveness of Statements; Survival of Provisions.

Determinations and statements of any Lender pursuant to Sections 2.9 and 2.10 shall be conclusive absent demonstrable error. Without limiting the generality of the foregoing, the Borrower shall have no right to review any records of any Lender or its other customers to determine the accuracy of any statement by that Lender under Section 2.9(a) regarding that Lender’s demands upon other customers of that Lender. Each Lender may use reasonable averaging and attribution methods in determining compensation pursuant to such Sections 2.9 and 2.10 and the provisions of Sections 2.9 and 2.10 shall survive termination of this Agreement.

Section 2.13 Computation of Interest and Fees.

All interest determined at the Floating Rate will be calculated based on the actual days elapsed in a year of 365 or 366 days, as the case may be. All interest determined at the LIBO Rate and all fees hereunder shall be computed on the basis of actual number of days elapsed in a year of 360 days.

Section 2.14 Purpose of Term Loan.

The proceeds of the Term Loan shall be used to finance the Cascade Acquisition and pay related transactional costs.

Representations and Warranties

The Borrower represents and warrants to the Lenders as follows:

Section 4.1 Existence and Power.

The Borrower is a corporation duly incorporated, validly existing and in good standing under the laws of Delaware, and is duly licensed or qualified to transact business in all jurisdictions where the character of the property owned or leased or the nature of the business transacted by it makes such licensing or qualification necessary, except where the failure to be so licensed or qualified (i) will not permanently preclude the Borrower from maintaining any material action in any such jurisdiction even though such action arose in whole or in part during the period of such failure, and (ii) will not result in any other Material Adverse Effect. The Borrower has all requisite power and authority, corporate or otherwise, to conduct its business, to own its properties and to execute and deliver, and to perform all of its obligations under, the Loan Documents.

Section 4.2 Authorization of Borrowing; No Conflict as to Law or Agreements.

The execution, delivery and performance by the Borrower of the Loan Documents and the borrowing hereunder have been duly authorized by all necessary corporate action and by all necessary public utilities commissions and any other regulatory bodies having jurisdiction over the Borrower, and do not and will not (i) require any consent or approval of the stockholders of the Borrower, or any authorization, consent or approval by any governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign, other than Authorizing Orders set forth in Schedule 4.2 that have been obtained and copies of which have been delivered to the Agent pursuant to Section 3.1, (ii) violate any provision of any law, rule or regulation (including, without limitation, Regulation X of the Board of Governors of the Federal Reserve System) or of any order, writ, injunction or decree presently in effect having applicability to the Borrower or of the articles of incorporation or bylaws of the Borrower, (iii) result in a breach of or constitute a default under any indenture or loan or credit agreement or any other agreement, lease or instrument to which the Borrower is a party or by which it or its properties may be bound or affected, or (iv) result in, or require, the creation or imposition of any Lien or other charge or encumbrance of any nature (other than those in favor of the Agent to secure one or more of the Obligations) upon or with respect to any of the properties now owned or hereafter acquired by the Borrower.

Section 4.3 Legal Agreements.

This Agreement and the other Loan Documents constitute the legal, valid and binding obligations of the Borrower enforceable against the Borrower in accordance with their respective terms, except to the extent that such enforcement may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors’ rights generally or by general equitable principles.

Section 4.4 Subsidiaries.

Schedule 4.4 hereto is a complete and correct list of all present Subsidiaries and of the percentage of the ownership of the Borrower or any other Subsidiary in each case as of the date of this Agreement. Except as otherwise indicated in that Schedule, all shares of each Subsidiary owned by the Borrower or by any such other Subsidiary are validly issued and fully paid and nonassessable.

Section 4.5 Financial Condition.

The Borrower has heretofore furnished to the Lenders its audited consolidated financial statement as of December 31, 2006, and its unaudited interim financial statement as of March 31, 2007. Those financial statements fairly present the financial condition of the Borrower and its Subsidiaries on the dates thereof and the results of their operations and cash flows for the periods then ended, and were prepared in accordance with GAAP, except as expressly noted therein.

Section 4.6 Adverse Change.

There has been no material adverse change in the business, properties or condition (financial or otherwise) of the Borrower since the date of the latest financial statement referred to in Section 4.5.

Section 4.7 Litigation.

Except as set forth in the Borrower’s Annual Report on Form 10-K for the year ended December 31, 2006, or in any document subsequently filed pursuant to Section 13, 14 or 15(d) of the Exchange Act, there are no actions, suits or proceedings pending or, to the knowledge of the Borrower, threatened against or affecting the Borrower or the properties of the Borrower, before any court or governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign, which, if determined adversely to the Borrower, would have a Material Adverse Effect.

Section 4.8 Environmental Matters.

The Borrower 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 Borrower 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, exclusive of Environmental Claims as set forth in the Borrower’s Annual Report on Form 10-K for the year ended December 31, 2006, or in any document subsequently filed pursuant to Section 13, 14 or 15(d) of the Exchange Act.

Section 4.9 Regulation U.

The Borrower is not engaged in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulation U of the Board of Governors of the Federal Reserve System), and no part of the proceeds of the Term Loan will be used to purchase or carry any margin stock or to extend credit to others for the purpose of purchasing or carrying any margin stock.

Section 4.10 Taxes.

The Borrower has filed all federal and other tax returns and reports required to be filed, and has paid all federal and other taxes, assessments, fees and other governmental charges levied or imposed upon it or its properties, income or assets otherwise due and payable, except those which are being contested in good faith by appropriate proceedings and for which adequate reserves have been provided in accordance with GAAP and except those the failure to file or pay which would not have a Material Adverse Effect. There is no proposed tax assessment against the Borrower that would, if made, have a Material Adverse Effect.

Section 4.11 Titles and Liens.

To the Borrower’s knowledge, without having undertaken any search of real property records for this purpose, the Borrower has good and sufficient title to, or valid leasehold interests in, all real property necessary or used in the ordinary conduct of its business, and good title to all other property and assets reflected in the Borrower’s most recent consolidated financial statements provided to the Lenders as owned by the Borrower, except for such defects in title as could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect and other than any sold, as permitted by Section 6.4. As of the date of this Agreement, the property of the Borrower is subject to no Liens other than a permitted pursuant to Section 6.1.

Section 4.12 Intellectual Property.

The Borrower owns or is licensed or otherwise has 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 its business, 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 Borrower, no slogan or other advertising device, product, process, method, substance, part or other material now employed, or now contemplated to be employed, by the Borrower 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 Borrower, proposed, which, in either case, could reasonably be expected to have a Material Adverse Effect.

Section 4.13 ERISA.

(a) Each Plan is in compliance in all material respects with ERISA, the Code and other applicable federal or state law. Each Plan which is intended to qualify under Section 401(a) of the Code has received a favorable determination letter from the Internal Revenue Service and, to the best knowledge of the Borrower, nothing has occurred which would or could reasonably be expected to cause the loss of such qualification of any such Plan or related trust.

(b) There are no pending or, to the best knowledge of the Borrower, threatened claims (other than routine claims for benefits in the ordinary course), actions or lawsuits, or action by any governmental authority, with respect to any Plan which has resulted or could reasonably be expected to result in a Material Adverse Effect. To the best knowledge of the Borrower, there has been no prohibited transaction within the meaning of Section 4975 of the Code or Section 406 ERISA or other material violation of the fiduciary responsibility rules with respect to any Plan which has resulted or could reasonably be expected to result in a Material Adverse Effect.

(c) No Reportable Event has occurred or is reasonably expected to occur with respect to any Pension Plan.

(d) The aggregate Unfunded Pension Liability for all Pension Plans (calculated based on the most recent actuarial report for each Pension Plan) does not exceed $25,000,000.

ARTICLE VIII

The Agent

Section 8.1 Authorization.

Each Lender and the holder of each Note irrevocably appoints and authorizes the Agent to act on behalf of such Lender or holder to the extent provided herein or in any document or instrument delivered hereunder or in connection herewith, and to take such other action as may be reasonably incidental thereto. In furtherance of the foregoing, and not in limitation thereof, each Lender irrevocably (i) authorizes the Agent to execute and deliver and perform its obligations under this Agreement and each of the Loan Documents to which the Agent is a party, and to exercise all rights, powers and remedies that the Agent may have hereunder or thereunder, (ii) appoints the Agent as nominal beneficiary or nominal secured party, as the case may be, under the Loan Documents and all related UCC-1 financing statements, and (iii) authorizes the Agent to act as agent of and for such Lender for purposes of holding, perfecting and disposing of any collateral under the Loan Documents. As to any matters not expressly provided for by this Agreement or the Loan Documents, the Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Required Lenders or, if so required pursuant to Section 9.2, upon the instructions of all Lenders; provided, however, that except for action expressly required of the Agent hereunder, the Agent shall in all cases be fully justified in failing or refusing to act hereunder unless it shall be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action, and the Agent shall not in any event be required to take any action which is contrary to this Agreement, the Loan Documents or applicable law. The Agent shall not have a fiduciary relationship in respect of the Borrower or any Lender by reason of this Agreement.

Section 8.2 Distribution of Payments and Proceeds.

(a) After deduction of any costs of collection, as provided in this Agreement and the other Loan Documents, and any fee payable to the Agent in its capacity as such under this Agreement, any Fee Letter or any other agreement, the Agent shall remit to each Lender that Lender’s Percentage of all payments of principal and interest and of all fees and other amounts payable hereunder for the benefit of the Lenders that are received by the Agent under the Loan Documents. Each Lender’s interest in the Loan Documents shall be payable solely from payments, collections and proceeds actually received by the Agent under the Loan Documents; and the Agent’s only liability to the Lenders hereunder shall be to account for each Lender’s Percentage of such payments, collections and proceeds in accordance with this Agreement. If the Agent is ever required for any reason to refund any such payments, collections or proceeds, each Lender will refund to the Agent, upon demand, its Percentage of such payments, collections or proceeds, together with its Percentage of interest or penalties, if any, payable by the Agent in connection with such refund.

(b) Notwithstanding the foregoing, if any Lender has wrongfully refused to fund its Percentage of the Term Loan as required hereunder, or if the principal balance of any Lender’s Note is for any other reason less than its Percentage of the aggregate principal balances of the Notes then outstanding, the Agent may remit all payments received by it to the other Lenders until such payments have reduced the aggregate amounts owed by the Borrower to the extent that the aggregate amount owing to such Lender hereunder is equal to its Percentage of the aggregate amount owing to all of the Lenders hereunder. The provisions of this paragraph are intended only to set forth certain rules for the application of payments, proceeds and collections in the event that a Lender has breached its obligations hereunder and shall not be deemed to excuse any Lender from such obligations.

Section 8.3 Expenses.

All payments, collections and proceeds received or effected by the Agent may be applied, first, to pay or reimburse the Agent for all costs, expenses, damages and liabilities at any time incurred by or imposed upon the Agent in connection with this Agreement or any other Loan Document (including but not limited to all reasonable attorney’s fees, foreclosure expenses and advances made to protect the security of any collateral). If the Agent does not receive payments, collections or proceeds sufficient to cover any such costs, expenses, damages or liabilities within 30 days after their incurrence or imposition, each Lender shall, upon demand, remit to the Agent its Percentage of the difference between (i) such costs, expenses, damages and liabilities, and (ii) such payments, collections and proceeds, together with interest on such amount for each day following the thirtieth day after demand therefor until so remitted at a rate equal to the Federal Funds Rate for each such day.

Section 8.4 Payments Received Directly by Lenders.

If any Lender or other holder of a Note shall obtain any payment or other recovery (whether voluntary, involuntary, by application of offset or otherwise) on account of the Obligations other than through distributions made in accordance with Section 8.2, such Lender or holder shall promptly give notice of such fact to the Agent and shall purchase from the other Lenders or holders such participations in the Obligations held by them as shall be necessary to cause the purchasing Lender or holder to share the excess payment or other recovery ratably with each of them; provided, however, that if all or any portion of the excess payment or other recovery is thereafter recovered from such purchasing Lender or holder, the purchase shall be rescinded and the purchasing Lender restored to the extent of such recovery (but without interest thereon).

Section 8.5 Indemnification.

Each Lender severally (but not jointly) hereby agrees to indemnify and hold harmless the Agent, as well as the Agent’s agents, employees, officers and directors, ratably according to their respective Percentages from and against any and all losses, liabilities (including liabilities for penalties), actions, suits, judgment, demands, damages, costs, disbursements, or expenses (including attorneys’ fees and expenses) of any kind or nature whatsoever, which are imposed on, incurred by, or asserted against the Agent or its agents, employees, officers or directors in any way relating to or arising out of this Agreement or the Loan Documents, or as a result of any action taken or omitted to be taken by the Agent; provided, however, that no Lender shall be liable for any portion of any such losses, liabilities (including liabilities for penalties), actions, suits, judgments, demands, damages, costs disbursements, or expenses resulting from the gross negligence or willful misconduct of the Agent. Notwithstanding any other provision of the Loan Documents, the Agent shall in all cases be fully justified in failing or refusing to act hereunder unless it shall be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action.

Section 8.6 Exculpation.

The Agent shall not be liable for any action taken or omitted to be taken by the Agent in connection with this Agreement or the Loan Documents, except for its own gross negligence or willful misconduct. The Agent shall be entitled to rely upon advice of counsel concerning legal matters, the advice of independent public accountants with respect to accounting matters and advice of other experts as to any other matters, and upon this Agreement, any Loan Document and any schedule, certificate, statement, report, notice or other writing which it believes to be genuine or to have been presented by a proper person. Neither the Agent nor any of its directors, officers, employees or agents shall (a) be responsible for any recitals, representations or warranties contained in, or for the execution, validity, genuineness, effectiveness or enforceability of this Agreement, any Loan Document, or any other instrument or document delivered hereunder or in connection herewith, (b) be responsible for the validity, genuineness, perfection, effectiveness, enforceability, existence, value or enforcement of any collateral security, (c) be under any duty to inquire into or pass upon any of the foregoing matters, or to make any inquiry concerning the performance by the Borrower or any other obligor of its obligations, or (d) in any event, be liable as such for any action taken or omitted by it or them, except for its or their own gross negligence or willful misconduct. The agency hereby created shall in no way impair or affect any of the rights and powers of, or impose any duties or obligations upon, the Agent in its individual capacity.

Section 8.7 Agent and Affiliates.

The Agent shall have the same rights and powers hereunder in its individual capacity as any other Lender, and may exercise or refrain from exercising the same as though it were not the Agent, and the Agent and its affiliates may accept deposits from and generally engage in any kind of business with the Borrower as fully as if the Agent were not the Agent hereunder.

Section 8.8 Credit Investigation.

Each Lender acknowledges that it has made such inquiries and taken such care on its own behalf as would have been the case had its obligations hereunder been incurred and its Percentage of the Term Loan made directly by such Lender to the Borrower without the intervention of the Agent or any other Lender. Each Lender agrees and acknowledges that the Agent makes no representations or warranties about the creditworthiness of the Borrower or any other party to this Agreement or with respect to the legality, validity, sufficiency or enforceability of this Agreement, any Loan Document, or any other instrument or document delivered hereunder or in connection herewith.

Section 8.9 Resignation and Assignment of Agent.

(a) The Agent may resign as such at any time upon at least 30 days’ prior notice to the Borrower and the Lenders. In the event of any resignation of the Agent, the Required Lenders shall as promptly as practicable appoint a successor Agent. If no such successor Agent shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the resigning Agent’s giving of notice of resignation, then the resigning Agent may, on behalf of the Lenders, appoint a successor Agent, which shall be a commercial bank organized under the laws of the United States of America or of any State thereof. Any such successor Agent shall have capital and retained earnings of at least $100,000,000.

(b) The Agent may, without the consent of the Borrower or the other Lenders, assign its rights and obligations as Agent hereunder and under the other Loan Documents to its parent or to any wholly owned subsidiary of its parent, and upon such assignment, the former Agent shall be deemed to have retired, and such wholly owned subsidiary shall be deemed to be a successor Agent. Any such successor Agent shall have capital and retained earnings of at least $100,000,000.

(c) Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon be entitled to receive from the prior Agent such documents of transfer and assignment as such successor Agent may reasonably request and the resigning or assigning Agent shall be discharged from its duties and obligations under this Agreement. After any resignation or assignment pursuant to this Section, the provisions of this Section shall inure to the benefit of the retiring Agent as to any actions taken or omitted to be taken by it while it was acting as Agent hereunder.

Section 8.10 Defaults.

The Agent shall not be deemed to have knowledge of the occurrence of a Default or an Event of Default unless the Agent has received notice from a Lender or the Borrower specifying the occurrence of such Default or Event of Default. In the event that the Agent receives such a notice of the occurrence of a Default or an Event of Default, the Agent shall give prompt notice thereof to the Lenders. The Agent shall (subject to Section 8.5 hereof) take such actions with respect to such Default as shall be directed by the Required Lenders; provided that, unless and until the Agent shall have received such directions, the Agent may take any action, or refrain from taking any action, with respect to such Default as it shall deem advisable in the best interest of the Lenders.

Section 8.11 Obligations Several.

The obligations of each Lender hereunder are the several obligations of such Lender, and neither any Lender nor the Agent shall be responsible for the obligations of any other Lender hereunder, nor will the failure by the Agent or any Lender to perform any of its obligations hereunder relieve the Agent or any other Lender from the performance of its respective obligations hereunder. Nothing contained in this Agreement, and no action taken by any Lender or the Agent pursuant hereto or in connection herewith or pursuant to or in connection with the Loan Documents shall be deemed to constitute the Lenders, together or with or without the Agent, as a partnership, association, joint venture, or other entity.

ARTICLE IX

Miscellaneous

Section 9.1 No Waiver; Cumulative Remedies.

No failure or delay on the part of the Lenders in exercising any right, power or remedy under the Loan Documents shall operate as a waiver thereof; nor shall any Lender’s acceptance of payments while any Default or Event of Default is outstanding operate as a waiver of such Default or Event of Default, or any right, power or remedy under the Loan Documents; nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy under the Loan Documents. The remedies provided in the Loan Documents are cumulative and not exclusive of any remedies provided by law.

Section 9.2 Amendments, Etc.

No amendment or waiver of any provision of any Loan Document or consent to any departure by the Borrower therefrom shall be effective unless the same shall be in writing and signed by the Required Lenders (or by the Agent with the consent or at the request of the Required Lenders), and any such waiver shall be effective only in the specific instance and for the specific purpose for which given. No notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances.

Notwithstanding the foregoing:

(a) No such amendment or waiver shall be effective to do any of the following unless signed by each of the Lenders (or by the Agent with the consent or at the request of each of the Lenders):

(i) Increase the Commitment Amount of any Lender or extend the Term Loan Funding Deadline.

(ii) Permit the Borrower to assign its rights under this Agreement.

(iii) Amend this Section, the definition of “Required Lenders” in Section 1.1, or any provision herein providing for consent or other action by all Lenders.

(b) No such amendment or waiver shall be effective to do any of the following unless signed by each of the Lenders affected thereby (or by the Agent with the consent or at the request of each of such Lenders):

(i) Forgive any indebtedness of the Borrower arising under this Agreement or the Notes, or reduce the rate of interest or any fees charged under this Agreement or the Notes.

(ii) Postpone or delay any date fixed by this Agreement or any other Loan Document for any payment of principal, interest, facility fees or other material amounts due to the Lenders (or any of them) hereunder or under any other Loan Document.

(c) No amendment, waiver or consent shall affect the rights or duties of the Agent under this Agreement or any other Loan Document unless in writing and signed by the Agent.

(d) No amendment, modification or (except as provided elsewhere herein) termination of this Agreement or waiver of any rights of the Borrower or obligations of any Lender or the Agent hereunder shall be effective unless the Borrower shall have consented thereto in writing.

Section 9.3 Notice.

Except as otherwise expressly provided herein, all notices and other communications hereunder shall be in writing and shall be (i) personally delivered, (ii) transmitted by registered mail, postage prepaid, (iii) sent by Federal Express or similar expedited delivery service, or (iv) transmitted by telecopy, in each case addressed to the party to whom notice is being given at its address or telecopier number (as the case may be) as set forth in Exhibit A or in any applicable Assignment Certificate; or, as to each party, at such other address or telecopier number as may hereafter be designated in a notice by that party to the other party complying with the terms of this Section. All such notices or other communications shall be deemed to have been given on (i) the date received if delivered personally or by mail, (ii) the date of receipt, if delivered by Federal Express or similar expedited delivery service, or (iii) the date of transmission if delivered by telecopy, except that notices or requests to the Agent or any Lender pursuant to any of the provisions of Article II shall not be effective until received.

Section 9.4 Costs and Expenses.

The Borrower agrees to pay on demand all reasonable costs and expenses incurred by the Agent in connection with the negotiation, preparation, execution, administration, amendment or enforcement of the Loan Documents and the other instruments and documents to be delivered hereunder and thereunder, including the reasonable fees and out-of-pocket expenses of counsel for any Lender with respect thereto, whether paid to outside counsel or allocated to the Agent by in-house counsel.

Section 9.5 Indemnification by Borrower.

The Borrower hereby agrees to indemnify the Agent and the Lenders and each officer, director, employee and agent thereof (herein individually each called an “Indemnitee” and collectively called the “Indemnitees”) from and against any and all losses, claims, damages, reasonable expenses (including, without limitation, reasonable attorneys’ fees) and liabilities incurred by an Indemnitee in connection with or arising out of the execution or delivery of this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or the use of the proceeds of the Term Loan (including but not limited to any such loss, claim, damage, expense or liability arising out of any claim in which it is alleged that any Environmental Law has been breached with respect to any activity or property of the Borrower), except to the extent that such loss, claim, damage, expense or liability was incurred as a result of the gross negligence or willful misconduct of the applicable Indemnitee. All obligations provided for in this Section shall survive any termination of this Agreement.

Section 9.6 Execution in Counterparts.

This Agreement and the other Loan Documents may be executed in any number of counterparts, each of which when so executed and delivered shall be deemed to be an original and all of which counterparts of this Agreement or such other Loan Document, as the case may be, taken together, shall constitute but one and the same instrument.

Section 9.7 Binding Effect; Assignment and Participations.

(a) Generally. The Loan Documents shall be binding upon and inure to the benefit of the Borrower and the Lenders and their respective successors and assigns, except that (i) the Borrower shall not have the right to assign its rights thereunder or any interest therein without the prior written consent of each of the Lenders, and (ii) except as set forth in this Section 9.7, no Lender may assign or grant any participation in any of its rights or obligations under any Loan Document.

(b) Participations. Any Lender may, at any time, grant participations in a portion of its Note and Commitment to any institutional investor on any date selected by such Lender. Any Lender proposing a participation hereunder shall give notice of such participation to the Agent at least ten Business Days prior to such participation (unless the Agent consents to a shorter period of time). Such notice shall specify the identity of the proposed purchaser of the participation and the amount of the proposed participation. No such partial participation shall be permitted if the principal amount thereof would be less than $5,000,000. No holder of any such participation, other than an affiliate of such Lender, shall be entitled to require such Lender to take or omit to take any action hereunder, except that such Lender may agree with such participant that such Lender will not, without such participant’s consent, (i) forgive any indebtedness of the Borrower under this Agreement or the Notes, (ii) agree to reduce the rate of interest charged under this Agreement, or (iii) agree to extend the final maturity of any indebtedness evidenced by the Notes, except as expressly provided by the terms of the Loan Documents. No Lender shall, as between the Borrower and such Lender, be relieved of any of its obligations hereunder as a result of any such granting of a participation. The Borrower hereby acknowledges and agrees that any participant described in this Section will, for purposes of Section 2.9, be considered to be a Lender hereunder (provided that such participant shall not be entitled to receive any more than the Lender selling such participation would have received had such sale not taken place) and may rely on, and possess all rights under, any opinions, certificates, or other instruments or documents delivered under or in connection with any Loan Document (it being understood that each opinion delivered hereunder speaks only as of the date thereof).

(c) Assignments. Any Lender may, at any time, assign a portion of its Note and Commitment to an Eligible Lender (an “Applicant”) on any date (the “Adjustment Date”) selected by such Lender. Any Lender proposing an assignment hereunder shall give notice of such assignment to the Agent at least ten Business Days prior to such assignment (unless the Agent consents to a shorter period of time). Such notice shall specify the identity of such Applicant and the Percentage which it proposes that such Applicant acquire (which Percentage shall be the same for the Commitment and the Note held by the assigning Lender). No such partial assignment shall be permitted if, immediately after giving effect to such assignment, either the Credit Exposure of the Applicant or the Credit Exposure of the assigning Lender would be less than $5,000,000. The notice of assignment shall contain a representation by the Applicant to the effect that none of the consideration used to make the purchase of the Note and Commitment under the applicable assignment agreement constitutes “plan assets” as defined under ERISA and that the rights and interests of the Applicant in and under the Loan Documents will not be “plan assets” under ERISA. Any Lender making an assignment under this Section shall pay the Agent a transfer fee in the amount of $3,500 simultaneously with such assignment.

(d) Consents. Any assignment hereunder may be made, and any participation granted, only with the prior written consent of the Agent and the Borrower; provided, however, that (i) in no event shall such consent be unreasonably withheld, (ii) the consent of the Borrower shall not be required if any Default or Event of Default has occurred and is continuing at the time of such assignment or grant of participation, (iii) no such consent of the Borrower and the Agent shall be required for the assignment by any Lender of, or grant of a participation in, all or any part of its Commitment and Note to one or more other Persons that are Lenders immediately prior to such assignment, and (iv) no such consent of the Borrower and the Agent shall be required for the assignment by any Lender of, or grant of a participation in, all or any part of its Commitment and Note to one or more affiliates of such Lender, provided that, unless consented to by the Borrower and the Agent (which consent shall not be unreasonably withheld), no such assignment under this clause (iv) shall relieve the transferring Lender from its obligations hereunder.

(e) Assignment Certificate and Notes. To confirm the status of each Additional Lender as a party to this Agreement and to evidence the assignment in accordance herewith:

(i) the Borrower, such Lender, such Applicant, and the Agent shall, on or before the Adjustment Date, execute and deliver to the Agent an Assignment Certificate in substantially the form of Exhibit D (an “Assignment Certificate”) (provided that the assignment will be effective without the signature of the Borrower or the Agent to the extent that the consent of the Borrower or the Agent, as the case may be, is not required hereunder); and

(ii) the Borrower will, at its own expense, execute and deliver to the Additional Lender a new Note, payable to the order of the Additional Lender in an amount corresponding to the applicable interest in the assigning Lender’s rights and obligations acquired by such Applicant pursuant to such assignment, and, if the assigning Lender has retained interests in such rights and obligations, a new Note, payable to the order of that Lender in an amount corresponding to such retained interests. Such new Notes shall be in an aggregate principal amount equal to the aggregate principal amount of the applicable Note to be replaced by such new Notes, shall be dated the effective date of such assignment and shall otherwise be in the form of the Note to be replaced thereby. Such new Notes shall be issued in substitution for, but not in satisfaction or payment of, the Notes being replaced thereby.

Upon the execution and delivery of such Assignment Certificate and such Notes, (a) this Agreement shall be deemed to be amended to the extent, and only to the extent, necessary to reflect the addition of such Additional Lender and the resulting adjustment of Percentages arising therefrom, (b) the assigning Lender shall be relieved of all obligations hereunder to the extent of the reduction of all obligations hereunder and to the extent of the reduction of such Lender’s Percentage, and (c) the Additional Lender shall become a party hereto and shall be entitled to all rights, benefits and privileges accorded to a Lender herein and in each other document or instrument executed pursuant hereto and subject to all obligations of a Lender hereunder, including the right to approve or disapprove actions which, in accordance with the terms hereof, require the approval of the Required Lenders or all Lenders, and, if the Term Loan has not yet been made, the obligation to advance its Percentage of the Term Loan hereunder.

(f) Federal Reserve Bank Security Interests. Notwithstanding the foregoing, each Lender may at any time grant a security interest in all or any portion of its rights under this Agreement and that Lender’s Note in favor of any Federal Reserve Bank in accordance with Regulation A of the Board of Governors of the Federal Reserve System.

(g) Borrower Cooperation. In order to facilitate the addition of Additional Lenders hereto, the Borrower shall cooperate fully with each Lender and the Agent in connection therewith and shall provide all reasonable assistance requested by each Lender and the Agent relating thereto, including, without limitation, the furnishing of such written materials and financial information regarding the Borrower as any Lender or the Agent may reasonably request, the execution of such documents as any Lender or the Agent may reasonably request with respect thereto, and the participation by officers of the Borrower in a meeting or teleconference call with any Applicant upon the reasonable request of any Lender or the Agent.

Section 9.8 Disclosure of Information.

The Agent and the Lenders shall keep confidential (and cause their respective officers, directors, employees, agents and representatives to keep confidential) all information, materials and documents furnished by the Borrower, the Agent or the Lenders (the “Disclosed Information”). Notwithstanding the foregoing, the Agent and each Lender may disclose Disclosed Information (i) to the Agent, any other Lender or any Affiliate of any Lender; (ii) to legal counsel, accountants and other professional advisors to the Agent or such Lender; (iii) to any regulatory body having jurisdiction over any Lender or the Agent; (iv) to the extent required by applicable laws and regulations or by any subpoena or similar legal process, or requested by any governmental agency or authority; (v) to the extent such Disclosed Information (A) becomes publicly available other than as a result of a breach of this Agreement, (B) becomes available to the Agent or such Lender on a non-confidential basis from a source other than the Borrower or a Subsidiary, or (C) was available to the Agent or such Lender on a non-confidential basis prior to its disclosure to the Agent or such Lender by the Borrower or a Subsidiary; (vi) to the extent the Borrower or such Subsidiary shall have consented to such disclosure in writing; (vii) to the extent reasonably deemed necessary by the Agent or any Lender in the enforcement of the remedies of the Agent and the Lenders provided under the Loan Documents; or (viii) in connection with any potential assignment or participation in the interest granted hereunder, provided that any such potential assignee or participant shall have executed a confidentiality agreement imposing on such potential assignee or participant substantially the same obligations as are imposed on the Agent and the Lenders under this Section 9.8.

Section 9.9 Governing Law.

The Loan Documents shall be governed by, and construed in accordance with, the laws of the State of New York.

Section 9.10 Consent to Jurisdiction.

Each of the Borrower, the Agent and the Lenders irrevocably (i) agrees that any suit, action or other legal proceeding arising out of or relating to this Agreement or any other Loan Document shall be brought in a court of record in Hennepin County in the State of Minnesota or in the courts of the United States located in such State, (ii) consents to the jurisdiction of each such court in any suit, action or proceeding, (iii) waives any objection which it may have to the laying of venue of any such suit, action or proceeding in any such courts and any claim that any such suit, action or proceeding has been brought in an inconvenient forum, and (iv) agrees that a final judgment in any such suit, 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 after all appeals have been exhausted.

Section 9.11 Waiver of Jury Trial.

THE BORROWER, THE AGENT AND THE LENDERS HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH THIS AGREEMENT AND THE NOTES OR THE RELATIONSHIPS ESTABLISHED HEREUNDER.

Section 9.12 Severability of Provisions.

Any provision of this Agreement which is prohibited or unenforceable shall be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof.

Section 9.13 Prior Agreements.

This Agreement and the other Loan Documents and related documents described herein restate and supersede in their entirety any and all prior agreements and understandings, oral or written, between the Lenders and the Borrower.

Section 9.14 Other Financing.

If at any time from and after the effective date of this Agreement, the Borrower shall enter into any trust indenture, credit agreement or other agreement for, relating to, or amending any terms or conditions applicable to any unsecured indebtedness in an amount not less than $15,000,000, the Borrower shall promptly so advise the Agent. Thereupon, if the Required Lenders shall determine that such trust indenture, credit agreement or other agreement includes covenants or defaults reasonably determined by the Required Lenders to be more restrictive than those provided for in Articles V and VI and shall request by notice to the Borrower, the Borrower shall enter into an amendment to this Agreement providing for substantially the same such covenants and defaults as those provided for in such trust indenture, credit agreement or other agreement, to the extent required and as may be selected by the Required Lenders, such amendment to remain in effect for the entire duration of the term to maturity of such indebtedness (to and including the date to which the same may be extended); provided, however, that if any such trust indenture, credit agreement or other agreement shall be modified, supplemented, amended or terminated so as to modify, amend or eliminate such trust indenture or other agreement or any such covenant, term, condition or default so made a part of this Agreement, then, the Borrower shall give the Agent and the Lenders prompt notice thereof and such modification, supplement or amendment shall operate to modify, amend or eliminate such covenants, term, condition or default as so made a part of this Agreement. Notwithstanding the foregoing, in no event shall this Section 9.14 be construed so as to require the Borrower at any time to grant any Lien in favor of the Agent or the Lenders hereunder.

Section 9.15 Headings.

Article and Section headings in this Agreement are included herein for convenience of reference only and shall not constitute a part of this Agreement for any other purpose.
