There may be no more than six (6) different Interest Periods in effect at any one time; provided, for purposes of determining the number of Interest Periods in effect at any one time, all Base Rate Loans shall be deemed to have one and the same Interest Period.

(b) Notice to the Banks. The Administrative Agent shall give prompt telephonic or telecopy notice to each Bank of any notice from Borrower received pursuant to Section 2.5(a) above. The Administrative Agent shall give notice to Borrower and each Bank by like means of the interest rate applicable to each Borrowing of Eurodollar Loans.

Not later than 12:00 noon (New York time) on the date of any requested advance of a new Borrowing of Eurodollar Loans, and not later than 2:00 p.m. (New York time) on the date of any requested advance of a new Borrowing of Base Rate Loans, subject to Section 6 hereof, each Bank shall make available its Loan comprising part of such Borrowing in funds immediately available at the principal office of the Administrative Agent in New York, New York.

(e) Administrative Agent Reliance on Bank Funding. Unless the Administrative Agent shall have been notified by a Bank before the date on which such Bank is scheduled to make payment to the Administrative Agent of the proceeds of a Loan (which notice shall be effective upon receipt) that such Bank does not intend to make such payment, the Administrative Agent may assume that such Bank has made such payment when due and the Administrative Agent may in reliance upon such assumption (but shall not be required to) make available to Borrower the proceeds of the Loan to be made by such Bank and, if any Bank has not in fact made such payment to the Administrative Agent, such Bank shall, on demand, pay to the Administrative Agent the amount made available to Borrower attributable to such Bank together with interest thereon in respect of each day during the period commencing on the date such amount was made available to Borrower and ending on (but excluding) the date such Bank pays such amount to the Administrative Agent at a rate per annum equal to (i) from the date the related payment was made by the Administrative Agent to the date two (2) Business Days after payment by such Bank is due hereunder, the Federal Funds Rate for each such day and (ii) from the date two (2) Business Days after the date such payment is due from such Bank to the date such payment is made by such Bank, the Base Rate in effect for each such day. If such amount is not received from such Bank by the Administrative Agent immediately upon demand, Borrower will, on demand, repay to the Administrative Agent the proceeds of the Loan attributable to such Bank with interest thereon at a rate per annum equal to the interest rate applicable to the relevant Loan.

Section 2.10 The Notes

(a) Upon the request of any Bank, the Loans made to Borrower by such Bank shall be evidenced by a single promissory note of Borrower issued to such Bank in the form of Exhibit A hereto. Each such promissory note is hereinafter referred to as a “Note” and collectively such promissory notes are referred to as the “Notes.”

(b) Each Bank shall record on its books and records or on a schedule to its Note the amount of each Loan advanced, continued, or converted by it, all payments of principal and interest and the principal balance from time to time outstanding thereon, the type of such Loan, and, for any Eurodollar Loan, the Interest Period and the interest rate applicable thereto. The record thereof, whether shown on such books and records of a Bank or on a schedule to any Note, shall be prima facie evidence of the same; provided, however, the failure of any Bank to record any of the foregoing or any error in any such record shall not limit or otherwise affect the obligation of Borrower to repay all Loans made hereunder together with accrued interest thereon. At the request of any Bank and upon such Bank tendering to Borrower the Note to be replaced, Borrower shall furnish a new Note to such Bank to replace any outstanding Note, and at such time the first notation appearing on a schedule on the reverse side of, or attached to, such Note shall set forth the aggregate unpaid principal amount of all Loans, if any, then outstanding thereon.

(a) any payment (whether by acceleration or otherwise), prepayment or conversion of a Eurodollar Loan on a date other than the last day of its Interest Period,

(b) any failure (because of a failure to meet the conditions of Section 6 or otherwise) by Borrower to borrow or continue a Eurodollar Loan, or to convert a Base Rate Loan into a Eurodollar Loan, on the date specified in a notice given pursuant to Section 2.5(a) or established pursuant to Section 2.5(c) hereof,

(c) any failure by Borrower to make any payment or prepayment of principal on any Eurodollar Loan when due (whether by acceleration or otherwise), or

(d) any acceleration of the maturity of a Eurodollar Loan as a result of the occurrence of any Event of Default hereunder,

(e) then, upon the demand of such Bank, Borrower shall pay to such Bank such amount as will reimburse such Bank for such loss, cost or expense. If any Bank makes such a claim for compensation, it shall provide to Borrower, with a copy to the Administrative Agent, a certificate executed by an officer of such Bank setting forth the amount of such loss, cost or expense in reasonable detail (including an explanation of the basis for and the computation of such loss, cost or expense) and the amounts shown on such certificate if reasonably calculated shall be prima facie evidence of the amount of such loss, cost or expense.

Section 2.12 Commitments. Borrower shall have the right at any time and from time to time, upon three (3) Business Days prior written notice to the Administrative Agent, to terminate the Commitments without premium or penalty (other than as set forth in the Initial Bank Fee Letter), in whole or in part, any partial termination to be (i) in an amount not less than $5,000,000 and integral multiples of $1,000,000 in excess thereof, and (ii) allocated ratably among the Banks in proportion to their respective Percentages, provided that the Commitments may not be reduced to an amount less than the sum of the Loans then outstanding. The Administrative Agent shall give prompt notice to each Bank of any such termination of Commitments. Any termination of Commitments pursuant to this Section 2.12 may not be reinstated. Additionally, prior to the making of the Term Loan, the Commitments shall be reduced by an amount equal to the net proceeds received by Borrower or any of its Subsidiaries pursuant to (i) Asset Dispositions which, either individually or in the aggregate, exceed $75,000,000 (in which case all Net Cash Proceeds in excess of such amount received in connection therewith shall reduce the Commitments) and (ii) other capital markets transactions which are undertaken to consummate the Related Transactions; for purposes of clarification, it is hereby acknowledged and agreed the issuance of approximately 4,170,000 shares of common stock of Borrower on February 22, 2007 through a private placement shall not be considered a capital markets transactions undertaken to consummate the Related Transactions pursuant to the foregoing clause (ii). All mandatory reductions of the Commitments pursuant to the immediately preceding sentence shall reduce the Commitment of each Bank on a pro rata basis in accordance with their respective Percentages.

(a) Commitment Fee. From and after the Effective Date until the date of the first Borrowing, Borrower shall pay to the Administrative Agent for the ratable account of the Banks in accordance with their Percentages a commitment fee accruing at a rate per annum equal to the Commitment Fee Rate on the full amount of the Commitment.

SECTION 5. REPRESENTATIONS AND WARRANTIES.

The Borrower hereby represents and warranties to each Bank each of the following are true, correct, and complete, both before and after giving effect to the Related Transactions:

Section 5.1 Corporate Organization and Authority. Borrower is duly organized and existing in good standing under the laws of the state of South Dakota; has all necessary corporate power to carry on its present business; and is duly licensed or qualified and in good standing in each jurisdiction in which the nature of the business transacted by it or the nature of the Property owned or leased by it makes such licensing, qualification or good standing necessary and in which the failure to be so licensed, qualified or in good standing would have a Material Adverse Effect.

Section 5.2 Subsidiaries. Schedule 5.2 (as updated from time to time pursuant to Section 7.1) hereto identifies each Subsidiary of Borrower, the jurisdiction of organization, the percentage of issued and outstanding equity securities owned by the Borrower and its Subsidiaries and, if such percentage is not one hundred percent (100%) (excluding directors’ qualifying shares as required by law), a description of each class of its equity securities and the number of securities issued and outstanding. Each Subsidiary is duly organized and existing in good standing under the laws of the jurisdiction of its organization, has all necessary corporate or equivalent power to carry on its present business, and is duly licensed or qualified and in good standing in each jurisdiction in which the nature of the business transacted by it or the nature of the Property owned or leased by it makes such licensing or qualification necessary and in which the failure to be so licensed or qualified would have a Material Adverse Effect. All of the issued and outstanding securities of each Subsidiary owned directly or indirectly by Borrower are validly issued and outstanding and fully paid and nonassessable except as set forth on Schedule 5.2 hereto. All such securities owned by Borrower are owned beneficially, and of record, free of any Lien, except as permitted in Section 7.9.

Section 5.3 Corporate Authority and Validity of Obligations. Borrower has full right and authority to enter into this Agreement and the other Credit Documents to which it is a party, to make the borrowings herein provided for, to issue its Notes in evidence thereof and to perform all of its obligations under the Credit Documents to which it is a party. Each Credit Document to which it is a party has been duly authorized, executed and delivered by Borrower and constitutes valid and binding obligations of Borrower enforceable in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforceability of creditors’ rights generally and by equitable principles of general applicability (regardless of whether such enforceability is considered in a proceeding in equity or at law). No Credit Document, nor the performance or observance by Borrower of any of the matters or things therein provided for, contravenes any provision of law or any charter or by-law provision of Borrower or any material Contractual Obligation of or affecting Borrower or any of Borrower’s Properties or results in or requires the creation or imposition of any Lien on any of the Properties or revenues of Borrower.

Section 5.4 Financial Statements. All financial statements heretofore delivered to the Banks showing historical performance of Borrower for Borrower’s fiscal years ending on or before December 31, 2006, have been prepared in accordance generally accepted accounting principles applied on a basis consistent, except as otherwise noted therein, with that of the previous fiscal year. Solely in the event they were publicly filed with the SEC prior to the Effective Date, the unaudited financial statements for the fiscal period ended March 31, 2007 have been prepared in accordance generally accepted accounting principles applicable to interim financial statements applied on a basis consistent, except as otherwise noted therein, with the previous same fiscal period of Borrower in the prior fiscal year (subject to normal year-end adjustments). Each of such financial statements fairly presents on a consolidated basis the financial condition of Borrower and its Subsidiaries as of the dates thereof and the results of operations for the periods covered thereby. Borrower and its Subsidiaries have no material contingent liabilities other than those disclosed in such financial statements referred to in this Section 5.4 or in comments or footnotes thereto, or in any report supplementary thereto, heretofore furnished to the Banks. Since December 31, 2006, there has been no event or series of events which has resulted in, or reasonably could be expected to result in, a Material Adverse Effect.

Section 5.5 No Litigation; No Labor Controversies.

(a) Except as set forth on Schedule 5.5, there is no litigation or governmental proceeding pending, or to the knowledge of Borrower, threatened, against Borrower or any Subsidiary of Borrower in which there is a reasonable possibility of an adverse decision which, if adversely determined, could (individually or in the aggregate) have a Material Adverse Effect.

(b) Except as set forth on Schedule 5.5, there are no labor controversies pending or, to the best knowledge of Borrower, threatened against Borrower or any Subsidiary of Borrower which could (individually or in the aggregate) have a Material Adverse Effect.

Section 5.6 Taxes. Borrower and its Subsidiaries have filed all United States federal tax returns, and all other foreign, state, local and other tax returns, required to be filed and have paid all taxes due pursuant to such returns or pursuant to any assessment received by Borrower or any Subsidiary of Borrower, except such taxes, if any, as are being contested in good faith and for which adequate reserves have been provided. No notices of tax liens have been filed and no claims are being asserted concerning any such taxes, which liens or claims are material to the financial condition of Borrower or any of its Subsidiaries (individually or in the aggregate). The charges, accruals and reserves on the books of Borrower and its Subsidiaries for any taxes or other governmental charges are adequate and in conformance with GAAP.

Section 5.7 Approvals. No authorization, consent, approval, license, exemption, filing or registration with any court or governmental department, agency or instrumentality which have not already been obtained, nor any approval or consent of the stockholders of Borrower or any Subsidiary of Borrower or from any other Person, is necessary to the valid execution, delivery or performance by Borrower or any Subsidiary of Borrower of any Credit Document to which it is a party.

Section 5.8 ERISA. With respect to each Plan, Borrower and each other member of the Controlled Group has fulfilled its obligations under the minimum funding standards of and is in compliance in all material respects with the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and with the Code to the extent applicable to it and has not incurred any liability to the Pension Benefit Guaranty Corporation (“PBGC”) or a Plan under Title IV of ERISA other than a liability to the PBGC for premiums under Section 4007 of ERISA.

The proceeds of the Loans are to be used solely to (i) consummate the Related Transactions, and (ii) pay fees, costs and expenses incurred in connection therewith. Borrower will not use the proceeds of any Loan in a manner that violates any provision of Regulation U or X of the Board of Governors of the Federal Reserve System.

Section 5.11 Licenses and Authorizations; Compliance with Laws.

(a) Borrower and each of its Subsidiaries has all necessary licenses, permits and governmental authorizations to own and operate its Properties and to carry on its business as currently conducted and contemplated. Borrower and each of its Subsidiaries is in compliance with all applicable laws, regulations, ordinances and orders of any governmental or judicial authorities except for any such law, regulation, ordinance or order which, the failure to comply therewith, could not reasonably expected to have a Material Adverse Effect.

(b) In the ordinary course of its business, Borrower and each of its Subsidiaries conduct an ongoing review of the effect of Environmental and Health Laws on the Properties and all aspects of the business and operations of such Borrower and its Subsidiaries in the course of which such Borrower identifies and evaluates associated liabilities and costs (including, without limitation, any capital or operating expenditures required for clean-up or closure of Properties currently or previously owned, any capital or operating expenditures required to achieve or maintain compliance with standards imposed by law and any actual or potential liabilities to third parties, including employees or governmental entities, and any related costs and expenses). On the basis of this review, Borrower has reasonably concluded that Environmental and Health Laws are unlikely to have any Material Adverse Effect.

(c) Except as set forth on Schedule 5.11 (as amended from time to time in accordance with the provisions hereof), neither the Borrower nor any Subsidiary of Borrower has given, nor is it required to give, nor has it received, any notice, letter, citation, order, warning, complaint, inquiry, claim or demand to or from any governmental entity or in connection with any court proceeding which could reasonably have a Material Adverse Effect claiming that: (i) Borrower or any Subsidiary of Borrower has violated, or is about to violate, any Environmental and Health Law; (ii) there has been a release, or there is a threat of release, of Hazardous Materials from Borrower’s or any of its Subsidiary’s Property, facilities, equipment or vehicles; (iii) Borrower or any of its Subsidiary may be or is liable, in whole or in part, for the costs of cleaning up, remediating or responding to a release of Hazardous Materials; or (iv) any of Borrower’s or any of its Subsidiary’s Property or assets are subject to a Lien in favor of any governmental entity for any liability, costs or damages, under any Environmental and Health Law arising from, or costs incurred by such governmental entity in response to, a release of a Hazardous Materials.

Section 5.14 Full Disclosure. All information heretofore furnished by Borrower to the Administrative Agent or any Bank for purposes of or in connection with the Credit Documents or any transaction contemplated thereby is, and all such information hereafter furnished by Borrower to the Administrative Agent or any Bank will be, true and accurate in all material respects and not misleading.

Section 5.15 Solvency. Borrower and each of its Subsidiaries, individually and on a consolidated basis, is Solvent

Section 5.16 Related Transactions. At the time the Banks extend the Term Loan to the Borrower in accordance with the terms of this Agreement, the only remaining condition precedent to consummation of each of the transactions contemplated by the Related Agreements in all material respects pursuant to the provisions of the Related Agreements shall be the making of such Term Loan. The consummation of the Related Transactions will be in compliance in all material respects with all applicable provisions of law.

Section 5.17 Certain Other Representations and Warranties

As of the Initial Loan Date (and, unless such representations and warranties are made only prior to or on the Initial Loan Date, any other date on which representations and warranties are otherwise remade or deemed remade hereunder), each of the representations and warranties contained in the Related Transaction Documents is true and correct. The Borrower agrees that, by this reference, such representations and warranties made in the Related Transaction Documents, without limiting any of the representations and warranties otherwise contained herein or in any other Credit Document, hereby are incorporated herein, mutatis mutandis, for the benefit of Administrative Agent and each Bank.

SECTION 9. CHANGE IN CIRCUMSTANCES.

Section 9.1 Change of Law. Notwithstanding any other provisions of this Agreement or any Note, if at any time after the date hereof any change in applicable law or regulation or in the interpretation thereof makes it unlawful for any Bank to make or continue to maintain Eurodollar Loans or to perform its obligations as contemplated hereby, such Bank shall promptly give notice thereof to Borrower and such Bank’s obligations to make or maintain Eurodollar Loans under this Agreement shall terminate until it is no longer unlawful for such Bank to make or maintain Eurodollar Loans. Borrower shall prepay on demand the outstanding principal amount of any such affected Eurodollar Loans, together with all interest accrued thereon at a rate per annum equal to the interest rate applicable to such Loan; provided, however, subject to all of the terms and conditions of this Agreement, Borrower may then elect to borrow the principal amount of the affected Eurodollar Loans from such Bank by means of Base Rate Loans from such Bank, which Base Rate Loans shall not be made ratably by the Banks but only from such affected Bank.

Section 9.2 Unavailability of Deposits or Inability to Ascertain, or Inadequacy of, LIBOR. If on or prior to the first day of any Interest Period for any Borrowing of Eurodollar Loans:

(a) the Administrative Agent determines that deposits in U.S. Dollars (in the applicable amounts) are not being offered to major banks in the eurodollar interbank market for such Interest Period, or that by reason of circumstances affecting the interbank eurodollar market adequate and reasonable means do not exist for ascertaining the applicable LIBOR, or

(b) Banks having more than thirty three percent (33%) or more of the aggregate amount of the Commitments reasonably determine and so advise the Administrative Agent that LIBOR as reasonably determined by the Administrative Agent will not adequately and fairly reflect the cost to such Banks or Bank of funding their or its Eurodollar Loans or Loan for such Interest Period,

then the Administrative Agent shall forthwith give notice thereof to Borrower and the Banks, whereupon until the Administrative Agent notifies Borrower that the circumstances giving rise to such suspension no longer exist, the obligations of the Banks or of the relevant Bank to make Eurodollar Loans shall be suspended.

Section 9.3 Increased Cost and Reduced Return.

(a) If, on or after the date hereof, the adoption of any applicable law, rule or regulation, or any change therein, 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 Bank (or its Lending Office) with any request or directive (whether or not having the force of law but, if not having the force of law, compliance with which is customary in the relevant jurisdiction) of any such authority, central bank or comparable agency:

(i) shall subject any Bank (or its Lending Office) to any tax, duty or other charge with respect to its Eurodollar Loans, its Notes or its participation in any thereof or its obligation to make Eurodollar Loans or to participate therein, or shall change the basis of taxation of payments to any Bank (or its Lending Office) of the principal of or interest on its Eurodollar Loans or participations therein or any other amounts due under this Agreement in respect of its Eurodollar Loans or participations therein or its obligation to make Eurodollar Loans or acquire participations therein (except for changes in the rate of tax on the overall net income or profits of such Bank or its Lending Office imposed by the jurisdiction in which such Bank or its lending office is incorporated in which such Bank’s principal executive office or Lending Office is located); or

(ii) shall impose, modify or deem applicable any reserve, special deposit or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System, but excluding with respect to any Eurodollar Loans any such requirement included in an applicable Eurodollar Reserve Percentage) against assets of, deposits with or for the account of, or credit extended by, any Bank (or its Lending Office) or shall impose on any Bank (or its Lending Office) or on the interbank market any other condition affecting its Eurodollar Loans, its Notes or its participation in any thereof or its obligation to make Eurodollar Loans or to participate therein;

and the result of any of the foregoing is to increase the cost to such Bank (or its Lending Office) of making or maintaining any Eurodollar Loan or participating therein, or to reduce the amount of any sum received or receivable by such Bank (or its Lending Office) under this Agreement or under its Notes with respect thereto, by an amount deemed by such Bank to be material, then, within fifteen (15) days after demand by such Bank (with a copy to the Administrative Agent), Borrower shall be obligated to pay to such Bank such additional amount or amounts as will compensate such Bank for such increased cost or reduction. In the event any law, rule, regulation or interpretation described above is revoked, declared invalid or inapplicable or is otherwise rescinded, and as a result thereof a Bank is determined to be entitled to a refund from the applicable authority for any amount or amounts which were paid or reimbursed by Borrower to such Bank hereunder, such Bank shall refund such amount or amounts to Borrower without interest.

(b) If, after the date hereof, any Bank or the Administrative Agent shall have determined that the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change therein (including, without limitation, any revision in the Final Risk-Based Capital Guidelines of the Board of Governors of the Federal Reserve System (12 CFR Part 208, Appendix A; 00 XXX Xxxx 000, Xxxxxxxx X) or of the Office of the Comptroller of the Currency (12 CFR Part 3, Appendix A), or in any other applicable capital rules heretofore adopted and issued by any governmental authority), 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 Bank (or its Lending Office) with any request or directive regarding capital adequacy (whether or not having the force of law but, if not having the force of law, compliance with which is customary in the applicable jurisdiction) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on such Bank’s capital, or on the capital of any corporation controlling such Bank, as a consequence of its obligations hereunder to a level below that which such Bank could have achieved but for such adoption, change or compliance (taking into consideration such Bank’s policies with respect to capital adequacy) by an amount deemed by such Bank to be material, then from time to time, within fifteen (15) days after demand by such Bank (with a copy to the Administrative Agent), Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank for such reduction.

(c) Each Bank that determines to seek compensation under this Section 9.3 shall notify Borrower and the Administrative Agent of the circumstances that entitle the Bank to such compensation pursuant to this Section 9.3 and will designate a different Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole judgment of such Bank, be otherwise disadvantageous to such Bank. A certificate of any Bank claiming compensation under this Section 9.3 and setting forth the additional amount or amounts to be paid to it hereunder submitted to Borrower and the Administrative Agent by such Bank in good faith shall be prima facie evidence of the amount of such compensation. In determining such amount, such Bank may use any reasonable averaging and attribution methods.

Section 9.4 Lending Offices. Each Bank may, at its option, elect to make its Loans hereunder at the branch, office or affiliate specified on the appropriate signature page hereof or in the assignment agreement which any assignee bank executes pursuant to Section 11.12 hereof (each a “Lending Office”) for each type of Loan available hereunder or at such other of its branches, offices or affiliates as it may from time to time elect and designate in a written notice to Borrower and the Administrative Agent, so long as such election does not increase costs or other amounts payable by Borrower to such Bank hereunder.

Section 9.5 Discretion of Bank as to Manner of Funding. Notwithstanding any other provision of this Agreement, each Bank shall be entitled to fund and maintain its funding of all or any part of its Loans in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if each Bank had actually funded and maintained each Eurodollar Loan through the purchase of deposits in the eurodollar interbank market having a maturity corresponding to such Loan’s Interest Period and bearing an interest rate equal to LIBOR for such Interest Period.

SECTION 10. THE AGENT.

Section 10.1 Appointment and Authorization of Administrative Agent. Each Bank hereby appoints ABN AMRO Bank N.V. as the Administrative Agent under the Credit Documents and hereby authorizes the Administrative Agent to take such action as Administrative Agent on its behalf and to exercise such powers under the Credit Documents as are delegated to the Administrative Agent by the terms thereof, together with such powers as are reasonably incidental thereto. The Administrative Agent shall have no duties or responsibilities except those expressly set forth in this Agreement and the Credit Documents. The duties of the Administrative Agent shall be mechanical and administrative in nature; the Administrative Agent shall not have by reason of this Agreement or any other Credit Document a fiduciary relationship in respect of any Bank, the holder of any Note or any other Person; and nothing in this Agreement or any other Credit Document, expressed or implied, is intended to or shall be so construed as to impose upon the Administrative Agent any obligations in respect of this Agreement or any other Credit Document except as expressly set forth herein or therein.

Section 10.2 Administrative Agent and its Affiliates. The Administrative Agent shall have the same rights and powers under this Agreement and the other Credit Documents as any other Bank and may exercise or refrain from exercising the same as though it were not the Administrative Agent, and the Administrative Agent and its affiliates may accept deposits from, lend money to, and generally engage in any kind of business with Borrower or any Affiliate of Borrower as if it were not the Administrative Agent under the Credit Documents.

Section 10.3 Action by Administrative Agent. If the Administrative Agent receives from Borrower a written notice of an Event of Default pursuant to Section 7.6(c)(i) hereof, the Administrative Agent shall promptly give each of the Banks written notice thereof. The obligations of the Administrative Agent under the Credit Documents are only those expressly set forth therein. Without limiting the generality of the foregoing, the Administrative Agent shall not be required to take any action hereunder with respect to any Default or Event of Default, except as expressly provided in Sections 8.2 and 8.3. In no event, however, shall the Administrative Agent be required to take any action in violation of applicable law or of any provision of any Credit Document, and the Administrative Agent shall in all cases be fully justified in failing or refusing to act hereunder or under any other Credit Document unless it shall be first indemnified to its reasonable satisfaction by the Banks against any and all costs, expense, and liability which may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall be entitled to assume that no Default or Event of Default exists unless notified to the contrary in writing by a Bank or Borrower. In all cases in which this Agreement and the other Credit Documents do not require the Administrative Agent to take certain actions, the Administrative Agent shall be fully justified in using its discretion in failing to take or in taking any action hereunder and thereunder.

Section 10.4 Consultation with Experts. The Administrative Agent may consult with legal counsel, independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts.

Section 10.5 Liability of Administrative Agent; Credit Decision. Neither the Administrative Agent nor any of its directors, officers, agents, or employees shall be liable for any action taken or not taken by it in connection with the Credit Documents (i) with the consent or at the request of the Required Banks or (ii) in the absence of its own gross negligence or willful misconduct. 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 (i) any statement, warranty or representation made in connection with this Agreement, any other Credit Document or any Borrowing; (ii) the performance or observance of any of the covenants or agreements of Borrower or any other party contained herein or in any other Credit Document; (iii) the satisfaction of any condition specified in Section 6 hereof; or (iv) the validity, effectiveness, genuineness, enforceability, perfection, value, worth or collectibility hereof or of any other Credit Document or of any other documents or writing furnished in connection with any Credit Document; and the Administrative Agent makes no representation of any kind or character with respect to any such matter mentioned in this sentence. The Administrative Agent may execute any of its duties under any of the Credit Documents by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Banks, Borrower, or any other Person for the default or misconduct of any such agents or attorneys-in-fact selected with reasonable care. The Administrative Agent shall not incur any liability by acting in reliance upon any notice, consent, certificate, other document or statement (whether written or oral) believed by it to be genuine or to be sent by the proper party or parties. In particular and without limiting any of the foregoing, the Administrative Agent shall have no responsibility for confirming the accuracy of any Compliance Certificate or other document or instrument received by it under the Credit Documents. The Administrative Agent may treat the payee of any Note as the holder thereof until written notice of transfer shall have been filed with the Administrative Agent signed by such payee in form satisfactory to the Administrative Agent. Each Bank acknowledges that it has independently and without reliance on the Administrative Agent or any other Bank, and based upon such information, investigations and inquiries as it deems appropriate, made its own credit analysis and decision to extend credit to Borrower in the manner set forth in the Credit Documents. It shall be the responsibility of each Bank to keep itself informed as to the creditworthiness of Borrower and any other relevant Person, and the Administrative Agent shall have no liability to any Bank with respect thereto.

Section 10.6 Indemnity. The Banks shall ratably, in accordance with their respective Percentages, indemnify and hold the Administrative Agent, and its directors, officers, employees, agents and representatives harmless from and against any liabilities, losses, costs or expenses suffered or incurred by it under any Credit Document or in connection with the transactions contemplated thereby, regardless of when asserted or arising, except to the extent the Administrative Agent is promptly reimbursed for the same by Borrower and except to the extent that any event giving rise to a claim was caused by the gross negligence or willful misconduct of the party seeking to be indemnified. The obligations of the Banks under this Section 10.6 shall survive termination of this Agreement.

Section 10.7 Resignation of Administrative Agent and Successor Administrative Agent. The Administrative Agent may resign at any time by giving written notice thereof to the Banks and Borrower. Upon any such resignation of the Administrative Agent, the Required Banks shall have the right to appoint a successor Administrative Agent with the consent of Borrower. If no successor Administrative Agent shall have been so appointed by the Required Banks, and shall have accepted such appointment, within thirty (30) days after the retiring Administrative Agent’s giving of notice of resignation, then the retiring Administrative Agent may, on behalf of the Banks, appoint a successor Administrative Agent, which shall be any Bank hereunder or any commercial bank organized under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $200,000,000. Upon the acceptance of its appointment as the Administrative Agent hereunder, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights and duties of the retiring or removed Administrative Agent under the Credit Documents, and the retiring Administrative Agent shall be discharged from its duties and obligations thereunder. After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this Section 10 and all protective provisions of the other Credit Documents shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent.

SECTION 11. MISCELLANEOUS.

Section 11.1 Withholding Taxes.

(a) Payments Free of Withholding. Subject to Section 11.1 (b) hereof, each payment by Borrower under this Agreement or the other Credit Documents shall be made without withholding for or on account of any present or future taxes (other than overall net income taxes on the recipient). If any such withholding is so required, Borrower shall make the withholding, pay the amount withheld to the appropriate governmental authority before penalties attach thereto or interest accrues thereon and forthwith pay such additional amount as may be necessary to ensure that the net amount actually received by each Bank and the Administrative Agent free and clear of such taxes (including such taxes on such additional amount) is equal to the amount which that Bank or the Administrative Agent (as the case may be) would have received had such withholding not been made. If the Administrative Agent or any Bank pays any amount in respect of any such taxes, penalties or interest Borrower shall reimburse the Administrative Agent or that Bank for that payment on demand in the currency in which such payment was made. If Borrower pay any such taxes, penalties or interest, they shall deliver official tax receipts evidencing that payment or certified copies thereof to the Bank or Administrative Agent on whose account such withholding was made (with a copy to the Administrative Agent if not the recipient of the original) on or before the thirtieth day after payment. If any Bank or the Administrative Agent determines it has received or been granted a credit against or relief or remission for, or repayment of, any taxes paid or payable by it because of any taxes, penalties or interest paid by Borrower and evidenced by such a tax receipt, such Bank or Administrative Agent shall, to the extent it can do so without prejudice to the retention of the amount of such credit, relief, remission or repayment, pay to Borrower such amount as such Bank or Administrative Agent determines is attributable to such deduction or withholding and which will leave such Bank or Administrative Agent (after such payment) in no better or worse position than it would have been in if Borrower had not been required to make such deduction or withholding. Nothing in this Agreement shall interfere with the right of each Bank and the Administrative Agent to arrange its tax affairs in whatever manner it thinks fit nor obligate any Bank or the Administrative Agent to disclose any information relating to its tax affairs or any computations in connection with such taxes.

(b) U.S. Withholding Tax Exemptions. Each Bank that is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) shall submit to Borrower and the Administrative Agent on or before the date of the Initial Loan Date two duly completed and signed copies of either Form W8BEN (relating to such Bank and entitling it to a complete exemption from withholding under the Code on all amounts to be received by such Bank, including fees, pursuant to the Credit Documents and the Loans) or Form W8ECI (relating to all amounts to be received by such Bank, including fees, pursuant to the Credit Documents and the Loans) of the United States Internal Revenue Service. Thereafter and from time to time, each Bank shall submit to Borrower and the Administrative Agent such additional duly completed and signed copies of one or the other of such Forms (or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities) as may be (i) requested by Borrower in a written notice, directly or through the Administrative Agent, to such Bank and (ii) required under then current United States law or regulations to avoid or reduce United States withholding taxes on payments in respect of all amounts to be received by such Bank, including fees, pursuant to the Credit Documents or the Loans.

(c) Inability of Bank to Submit Forms. If any Bank determines, as a result of any change in applicable law, regulation or treaty, or in any official application or interpretation thereof, that it is unable to submit to Borrower or Administrative Agent any form or certificate that such Bank is obligated to submit pursuant to subsection (b) of this Section 11.1 or that such Bank is required to withdraw or cancel any such form or certificate previously submitted or any such form or certificate otherwise becomes ineffective or inaccurate, such Bank shall promptly notify Borrower and Administrative Agent of such fact and the Bank shall to that extent not be obligated to provide any such form or certificate and will be entitled to withdraw or cancel any affected form or certificate, as applicable.

Section 11.2 No Waiver of Rights. No delay or failure on the part of the Administrative Agent or any Bank or on the part of the holder or holders of any Note in the exercise of any power or right under any Credit Document shall operate as a waiver thereof, nor as an acquiescence in any default, nor shall any single or partial exercise thereof preclude any other or further exercise of any other power or right, and the rights and remedies hereunder of the Administrative Agent, the Banks and the holder or holders of any Notes are cumulative to, and not exclusive of, any rights or remedies which any of them would otherwise have.

Section 11.3 Non-Business Day. If any payment of principal or interest on any Loan or of any other Obligation shall fall due on a day which is not a Business Day, interest or fees (as applicable) at the rate, if any, such Loan or other Obligation bears for the period prior to maturity shall continue to accrue on such Obligation from the stated due date thereof to and including the next succeeding Business Day, on which the same shall be payable.

Section 11.4 Documentary Taxes. Borrower agrees that it will pay any documentary, stamp or similar taxes payable in respect to any Credit Document, including interest and penalties, in the event any such taxes are assessed, irrespective of when such assessment is made and whether or not any credit is then in use or available hereunder.

Section 11.5 Survival of Representations. All representations and warranties made herein or in certificates given pursuant hereto shall survive the execution and delivery of this Agreement and the other Credit Documents, and shall continue in full force and effect with respect to the date as of which they were made as long as any credit is in use or available hereunder.

Section 11.6 Survival of Indemnities. All indemnities and all other provisions relative to reimbursement to the Banks of amounts sufficient to protect the yield of the Banks with respect to the Loans, including, but not limited to, Section 2.11, Section 9.3 and Section 11.13 hereof, shall survive the termination of this Agreement and the other Credit Documents and the payment of the Loans and all other Obligations.

Section 11.7 Set-Off.

(a) In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, upon the occurrence of any Event of Default, each Bank and each subsequent holder of any Note is hereby authorized by Borrower at any time or from time to time, without notice to Borrower or to any other Person, any such notice being hereby expressly waived, to set off and to appropriate and to apply any and all deposits (general or special, including, but not limited to, Indebtedness evidenced by certificates of deposit, whether matured or unmatured, or otherwise fully matured, and in whatever currency denominated) and any other Indebtedness at any time held or owing by that Bank or that subsequent holder to or for the credit or the account of Borrower, whether or not matured, against and on account of the obligations and liabilities of Borrower to that Bank or that subsequent holder under the Credit Documents, including, but not limited to, all claims of any nature or description arising out of or connected with the Credit Documents, irrespective of whether or not (a) that Bank or that subsequent holder shall have made any demand hereunder or (b) the principal of or the interest on the Loans or Notes and other amounts due hereunder shall have become due and payable pursuant to Section 8 and although said obligations and liabilities, or any of them, may be contingent or unmatured.

(b) Each Bank agrees with each other Bank a party hereto that if such Bank shall receive and retain any payment, whether by set-off or application of deposit balances or otherwise, on any of the Loans in excess of its ratable share of payments on all such obligations then outstanding to the Banks, then such Bank shall purchase for cash at face value, but without recourse, ratably from each of the other Banks such amount of the Loans or participations therein, held by each such other Banks (or interest therein) as shall be necessary to cause such Bank to share such excess payment ratably with all the other Banks; provided, however, that if any such purchase is made by any Bank, and if such excess payment or part thereof is thereafter recovered from such purchasing Bank, the related purchases from the other Banks shall be rescinded ratably and the purchase price restored as to the portion of such excess payment so recovered, but without interest.

Section 11.8 Notices. Except as otherwise specified herein, all notices under the Credit Documents shall be in writing (including facsimile or other electronic communication) and shall be given to a party hereunder at its address or facsimile number set forth below or such other address or facsimile number as such party may hereafter specify by notice to the Administrative Agent and Borrower, given by courier, by United States certified or registered mail, or by other telecommunication device capable of creating a written record of such notice and its receipt.

Delivery of an executed counterpart hereof via facsimile or electronic means shall for all purposes be as effective as delivery of an original counterpart.

Section 11.10 Successors and Assigns.

(a) Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign any of its rights or obligations under any Credit Document unless such assignation occurs in connection with a merger or acquisition by Borrower which is otherwise permitted under the terms of this Agreement and the appropriate Credit Documents, if applicable, and Borrower obtains the prior written consent of all of the Banks, which consent shall be in form and substance satisfactory to the Administrative Agent. No Bank may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of paragraph (d) of this Section or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in paragraph (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Banks) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Assignments by Banks. Any Bank may at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that

(i) except in the case of an assignment (x) of the entire remaining amount of the assigning Bank’s Commitment and the Loans at the time owing to it or (y) to a Bank or an Affiliate of a Bank or an Approved Fund with respect to a Bank, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loan of the assigning Bank subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $5,000,000, unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower, otherwise consents (neither such consent not to be unreasonably withheld or delayed);

(ii) each such assignment (other than assignments by a Bank to another Bank or an Affiliate of or an Approved Fund with respect to a Bank) shall be subject to the consent of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower (neither such consent to be unreasonably withheld or delayed);

(iii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Bank’s rights and obligations under this Agreement with respect to the Loan or the Commitment assigned;

(iv) any assignment of a Commitment must be approved by the Administrative Agent unless the Person that is the proposed assignee is itself a Bank with a Commitment (whether or not the proposed assignee would otherwise qualify as an Eligible Assignee); and

(v) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500, and the Eligible Assignee, if it shall not be a Bank, shall deliver to the Administrative Agent an Administrative Questionnaire.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Bank under this Agreement, and the assigning Bank thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Bank’s rights and obligations under this Agreement, such Bank shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 9.3 and 9.4 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Bank of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Bank of a participation in such rights and obligations in accordance with paragraph (d) of this Section. The Borrower shall execute and deliver to the assignee a Note upon written request from such assignee. The assignor shall promptly return to the Borrower its Note if after giving effect to such assignment such assignor has no Commitment and no Obligations are owing to such assignor.

(c) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in Chicago, Illinois a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Banks, and the Commitments of, and principal amounts of the Loans owing to, each Bank pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Banks may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Bank hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Bank, at any reasonable time and from time to time upon reasonable prior notice.

(d) Participations. Any Bank may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Bank’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Bank’s obligations under this Agreement shall remain unchanged, (ii) such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the other Banks shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under this Agreement.

(e) Any agreement or instrument pursuant to which a Bank sells such a participation shall provide that such Bank shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Bank will not, without the consent of the Participant, agree to any amendment, modification or waiver of the type described in Section 11.11(i) that affects such Participant. Subject to paragraph (e) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 9.3 and 9.4 to the same extent as if it were a Bank and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.7(a) as though it were a Bank, provided such Participant agrees to be subject to Section 11.7(b) as though it were a Bank.

(f) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Sections 9.3 and 9.4 than the applicable Bank would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Bank if it were a Bank shall not be entitled to the benefits of Section 9.4 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 9.4 as though it were a Bank.

(g) Certain Pledges. Any Bank may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Bank, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Bank from any of its obligations hereunder or substitute any such pledgee or assignee for such Bank as a party hereto.

(h) Certain Funding Arrangements. Notwithstanding anything to the contrary contained herein, any Bank (a “Granting Bank”) may grant to a special purpose funding vehicle which is an Affiliate of such Bank (a “SPC”), identified as such in writing from time to time by the Granting Bank to the Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Loan that such Granting Bank would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Loan, and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Bank shall be obligated to make such Loan pursuant to the terms hereof. The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Bank to the same extent, and as if, such Loan were made by such Granting Bank. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Bank). In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary contained in this Section 11.10, any SPC may (i) with notice to, but without the prior written consent of, the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loans to the Granting Bank or to any financial institutions (consented to by the Borrower and Administrative Agent) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Loans and (ii) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. This section may not be amended without the written consent of the SPC.

(i) Farm Credit System. Notwithstanding anything in this Section to the contrary, any bank that is a member of the Farm Credit System that: (x) has purchased a participation in the minimum amount of $10,000,000 on or after the Effective Date, (y) is, by written notice to the Borrower and the Administrative Agent ("Voting Participant Notification"), designated by the selling Bank as being entitled to be accorded the rights of a Voting Participant hereunder (any bank that is a member of the Farm Credit System so designated being called a "Voting Participant") and (z) receives the prior written consent of the Borrower and the Administrative Agent to become a Voting Participant, shall be entitled to vote (and the voting rights of the selling Bank shall be correspondingly reduced), on a dollar for dollar basis, as if such participant were a Bank, on any matter requiring or allowing a Bank to provide or withhold its consent, or to otherwise vote on any proposed action. To be effective, each Voting Participant Notification shall, with respect to any Voting Participant: (i) state the full name, as well as all contact information required of an Assignee as set forth in Exhibit D hereto and (ii) state the dollar amount of the participation purchased. The Borrower and the Administrative Agent shall be entitled to conclusively rely on information contained in notices delivered pursuant to this paragraph.

Section 11.11 Amendments. Any provision of the Credit Documents may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by (a) Borrower, (b) the Required Banks, and (c) if the rights or duties of the Administrative Agent are affected thereby, the Administrative Agent; provided that:

(i) no amendment or waiver pursuant to this Section. 11.11 shall (A) increase, decrease or extend any Commitment of any Bank without the consent of such Bank or (B) reduce the amount of or postpone any fixed date for payment of any principal of or interest on any Loan or of any fee or other Obligation payable hereunder without the consent of each Bank; and

(ii) no amendment or waiver pursuant to this Section 11.11 shall, unless signed by each Bank, change this Section 11.11, or the definition of Required Banks, or affect the number of Banks required to take any action under the Credit Documents.

Anything in this Agreement to the contrary notwithstanding, if at any time when the conditions precedent set forth in Section 6.2 hereof to any Loan hereunder are satisfied, any Bank shall fail to fulfill its obligations to make such Loan (any such Bank, a “Defaulting Bank”) then, for so long as such failure shall continue, the Defaulting Bank shall (unless Borrower, the Administrative Agent and the Required Banks (determined as if the Defaulting Bank were not a Bank hereunder) shall otherwise consent in writing) be deemed for all purposes related to amendments, modifications, waivers or consents under this Agreement (other than amendments or waivers referred to in clause (i) and (ii) above) to have no Loans or Commitments and shall not be treated as a Bank hereunder when performing the computation of the Required Banks. To the extent the Administrative Agent receives any payments or other amounts for the account of a Defaulting Bank such Defaulting Bank shall be deemed to have requested that the Administrative Agent use such payment or other amount to fulfill its obligations to make such Loan.

Section 11.12 Headings. Section headings used in this Agreement are for reference only and shall not affect the construction of this Agreement.

Section 11.13 Legal Fees, Other Costs and Indemnification. Borrower agrees to pay all reasonable costs and expenses of the Administrative Agent and each Co-Arranger (in their respective roles as Banks hereunder) in connection with the preparation and negotiation of the Credit Documents (including past and future reasonable out-of-pocket expenses incurred by the Administrative Agent and each Co-Arranger (in their respective roles as Banks hereunder) in connection with the syndication of the transaction), including without limitation, the reasonable fees and disbursements of counsel to the Administrative Agent and Co-Arranger (in their respective roles as Banks hereunder), in connection with the preparation and execution of the Credit Documents, and any amendment, waiver or consent related hereto, whether or not the transactions contemplated herein are consummated. Borrower further agrees to indemnify each Bank, the Administrative Agent and their respective directors, agents, officers and employees, against all losses, claims, damages, penalties, judgments, liabilities and expenses (including, without limitation, all expenses of litigation or preparation therefor, whether or not the indemnified Person is a party thereto) which any of them may incur or reasonably pay arising out of or relating to any Credit Document (including any relating to a misrepresentation by Borrower under any Credit Document) or any of the transactions contemplated thereby or the direct or indirect application or proposed application of the proceeds of any Loan, other than those which arise from the gross negligence or willful misconduct of the party claiming indemnification. Borrower, upon demand by any of the Administrative Agent or a Bank at any time, shall reimburse the Administrative Agent or such Bank for any reasonable legal or other expenses (including allocable fees and expenses of in-house counsel) incurred in connection with investigating or defending against any of the foregoing except if the same is directly due to the gross negligence or willful misconduct of the party to be indemnified, provided that with respect to legal costs and expenses incurred in connection with the enforcement of the Banks rights hereunder or any work-out or similar situation, Borrower shall only be obligated to pay the legal fees of the Administrative Agent and each Co-Arranger (in their respective roles as Banks hereunder) and not of any other Bank. Solely for purposes of this Section 11.13, in the event a Co-Arranger is not a Bank but an Affiliate of such Co-Arranger is a Bank hereunder, such Affiliate shall be deemed such a Co-Arranger under this Section 11.13.

Section 11.14 Entire Agreement. The Credit Documents constitute the entire understanding of the parties thereto with respect to the subject matter thereof and any prior or contemporaneous agreements, whether written or oral, with respect thereto are superseded thereby.

Section 11.15 Construction. The parties hereto acknowledge and agree that neither this Agreement nor the other Credit Documents shall be construed more favorably in favor of one than the other based upon which party drafted the same, it being acknowledged that all parties hereto contributed substantially to the negotiation of this Agreement and the other Credit Documents.

Section 11.16 Governing Law. This Agreement and the other Credit Documents, and the rights and duties of the parties hereto, shall be construed and determined in accordance with the internal laws of the State of New York.

BORROWER IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. BORROWER HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO ANY CREDIT DOCUMENT OR THE TRANSACTIONS CONTEMPLATED THEREBY.

Section 11.18 Replacement of Bank. Each Bank agrees that, upon the occurrence of any event set forth in Sections 9.1, 9.3 and 11.1, such Bank will use reasonable efforts to book and maintain its Loans through a different Lending Office or to transfer its Loans to an Affiliate with the objective of avoiding or minimizing the consequences of such event; provided that such booking or transfer is not otherwise disadvantageous to such Bank as determined by such Bank in its sole and absolute discretion. If any Bank has demanded to be paid additional amounts pursuant to Sections 9.1, 9.3 and 11.1, and the payment of such additional amounts are, and are likely to continue to be, more onerous in the reasonable judgment of Borrower than with respect to the other Banks, then Borrower shall have the right at any time when no Default or Event of Default shall have occurred and be continuing to seek one or more financial institutions which are not Affiliates of Borrower (each, a “Replacement Bank”) to purchase with the written consent of the Administrative Agent (which consent shall not be (x) required if such proposed Replacement Bank is already a Bank, or an Affiliate of a Bank, or (y) unreasonably delayed or withheld) the outstanding Loans and Commitments of such Bank (the “Affected Bank”), and if Borrower locate a Replacement Bank, the Affected Bank shall, upon

i.	prior written notice to the Administrative Agent,

ii.

(i) payment to the Affected Bank of the purchase price agreed between it and the Replacement Bank (or, failing such agreement, a purchase price in the amount of the outstanding principal amount of the Affected Bank’s Loans and accrued interest thereon to the date of payment) by the Replacement Bank plus (ii) payment by Borrower of all Obligations (other than principal and interest with respect to Loans) then due to the Affected Bank or accrued for its account hereunder or under any other Loan Document,

iii.	satisfaction of the provisions set forth in Section 11.10, and

iv.	payment by Borrower to the Affected Bank and the Administrative Agent of all reasonable out-of-pocket expenses in connection with such assignment and assumption (including the recordation fee described in Section 11.10),

assign and delegate all its rights and obligations under this Agreement and any other Credit Document to which it is a party (including its outstanding Loans) to the Replacement Bank (such assignment to be made without recourse, representation or warranty), and the Replacement Bank shall assume such rights and obligations, whereupon the Replacement Bank shall in accordance with Section 11.10 become a party to each Credit Document to which the Affected Bank is a party and shall have the rights and obligations of a Bank thereunder and the Affected Bank shall be released from its obligations hereunder and each other Credit Document to the extent of such assignment and delegation.

Section 11.19 Confidentiality. The Administrative Agent and the Banks shall hold all non-public information provided to them by Borrower pursuant to or in connection with this Agreement in accordance with their customary procedures for handling confidential information of this nature, but may make disclosure to any of their examiners, regulators, Affiliates, outside auditors, counsel and other professional advisors in connection with this Agreement or any other Credit Document or as reasonably required by any potential bona fide transferee, participant or assignee, or in connection with the exercise of remedies under a Credit Document, or to any direct or indirect contractual counterparty in swap agreements or such contractual counterparty’s professional advisor (so long as such contractual counterparty or professional advisor to such contractual counterparty agrees to be bound by the provisions of this Section 11.19), or to any nationally recognized rating agency that requires access to information about a Bank’s investment portfolio in connection with ratings issued with respect to such Bank, or as requested by any governmental agency or representative thereof or pursuant to legal process; provided, however, that unless specifically prohibited by applicable law or court order, the Administrative Agent and each Bank shall use reasonable efforts to promptly notify Borrower of any request by any governmental agency or representative thereof (other than any such request in connection with an examination of the financial condition of the Administrative Agent or such Bank by such governmental agency) for disclosure of any such non-public information and, where practicable, prior to disclosure of such information. Prior to any such disclosure pursuant to this Section 11.19, the Administrative Agent and each Bank shall require any such bona fide transferee, participant and assignee receiving a disclosure of non-public information to agree, for the benefit of Borrower, in writing to be bound by this Section 11.19; and to require such Person to require any other Person to whom such Person discloses such non-public information to be similarly bound by this Section 11.19.

Notwithstanding anything herein to the contrary, “confidential information” shall not include, and the Administrative Agent and each Bank may disclose to any and all persons, without limitation of any kind, any information with respect to the U.S. federal income tax treatment and U.S. federal income 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 or such Bank relating to such tax treatment and tax structure.

Section 11.20 Rights and Liabilities of Syndication Agents, Sole Bookrunner and Co-Arrangers.

SCHEDULE 5.5

LITIGATION AND LABOR CONTROVERSIES

1. Grizzly Gulch Fire

On June 29, 2002, a forest fire began near Deadwood, South Dakota. Before being contained more than eight days later, the fire consumed over 10,000 acres of public and private land, mostly consisting of rugged forested areas. The fire destroyed approximately 7 homes, and 15 outbuildings. On July 16, 2002, the State of South Dakota announced the results of its investigation of the cause and origin of the fire. The State asserted that the fire was caused by tree encroachment into and contact with a transmission line owned and maintained by Black Hills Power, Inc. (“BHP”).

The State of South Dakota and the United States of America commenced litigation against BHP in the United States District Court, District of South Dakota, Western Division. The Complaint sought recovery of damages for alleged injury to timber, fire suppression and rehabilitation costs. A claim for treble damages was asserted with respect to the claim for injury to timber. On August 25, 2006, the U.S. District Court approved a full and final settlement of all governmental claims relating to the Grizzly Gulch Fire. The settlement agreement provided for the release and dismissal of all claims against BHP. For its part, BHP does not admit liability for the fire, but agreed to make payments as follows: (1) Payment of $2.3 million dollars to the State of South Dakota; (2) Payment of $1 million dollars to the State’s “Special Emergency Disaster Revenue Fund”; and (3) Payment of $3.6 million dollars to the United States Government.

While the governmental case was pending, a number of private claims for damages arising out of the Grizzly Gulch Fire were filed in Xxxxxxxx County Circuit Court, South Dakota. Counsel for these litigants agreed to a stay of the proceedings pending the resolution of governmental claims. As a result of the settlement of the governmental cases, the private claims are now proceeding through discovery. No trial date or other scheduling order has been set for these matters. Additional claims could be asserted for alleged loss of habitat and aesthetics or for assistance to private landowners, but those currently on file are listed below. None of these claims, individually or in the aggregate, are expected to have a material impact on the Company’s consolidated financial position or results of operations.

2. Earn-Out Litigation

On August 13, 2004, Xxxxxx X. Xxxxxxxx and other individuals identified at “Stockholders” under an Agreement and Plan of Merger dated July 7, 2000, commenced litigation against Black Hills Corporation in United States District Court, Northeastern District of Illinois, Eastern Division (the “Litigation”). The Litigation concerns the Company’s performance of its obligations under the “Earn-Out” provisions of the Agreement and Plan of Merger. Under these provisions, the Stockholders, who are former owners of Indeck Capital, Inc., were entitled to receive “contingent merger consideration” for a period of four years following the merger of Indeck Capital with Black Hills Energy Capital, Inc. (“BHEC”). The Stockholders allege that Black Hills failed to meet its obligation to produce documentation for its calculation of the contingent merger consideration, and in addition, failed to issue stock compensation in the full amount due to them. Black Hills denies these allegations and contends that it has fully and in good faith performed all of its obligations under the Agreement and Plan of Merger.

In addition, Black Hills contended that the Agreement and Plan of Merger provides for mandatory arbitration as a medium for resolution of all disputes relating to the payment of contingent merger consideration. Black Hills filed a Motion to Dismiss or Stay the Litigation, along with an order compelling the Stockholders to pursue their claims in arbitration. On July 7, 2005, the U.S. District Court entered its order compelling arbitration of two issues relating to the Earn Out calculation, but held that two other issues (inter-company interest allocations and capitalization of BHEC) would remain subject to determination through the Litigation. The court declined to stay the Litigation on those two issues and consequently, this dispute will be resolved in parallel proceedings. The discovery deadline currently provides for the completion of discovery in early 2007. No trial date has been set.

On October 6, 2006, the Court granted Plaintiffs’ Motion to Amend the Complaint to add two new claims, and re-characterize others. Under the Amended Complaint, a count for breach of contract was withdrawn and replaced by similar allegations under a theory of breach of the covenant of good faith and fair dealing. The first new count seeks damages for alleged destruction or “spoliation” of corporate records relating to the Earn Out process and obligation. The second claim asserts damages for alleged fraud, and seeks recovery against current and former officers of the Company, as well as the Company itself. The fraud theory alleges that if a written promissory note was not executed to evidence inter-company loans, the debt represented by those transactions would be “non-existent”, and representations by the Company to the contrary would be fraudulent. The Company hired separate counsel for the individual defendants and filed a Motion to Dismiss the Amended Complaint.

On March 12, 2007, the Court granted the Company’s Motion to Dismiss, in part. First, the Court dismissed Counts 1 and 5 of the Amended Complaint. Count 1 included all claims of fraud against individual defendants. Those individuals were not named in other counts of the Amended Complaint, so they are dismissed as parties to the lawsuit. Count 5 asserted a claim for breach of the covenant of good faith and fair dealing relating to the alleged destruction of evidence. The Court approved the amendment of the complaint on other theories. The Company expects to file Motions for Summary Judgment on these remaining claims.

A status hearing is set for late June, 2007, at which time we expect the Court to set a trial date, if Motions for Summary Judgment are denied in whole or in part.

The parties retained an arbitrator who will direct the process and decide the issues in arbitration, according to the procedure stated in the Merger Agreement. No process or time schedule for the arbitration has been established. The outcome of this matter is uncertain, as is the amount of contingent merger consideration that could be awarded following arbitration and/or litigation.

3. California Price Reporting and Anti-Trust Litigation

On August 17, 2006, Enserco Energy Inc. was served as an additional defendant in sixteen lawsuits pending in San Diego Superior Court, in the State of California. The plaintiffs are purported natural gas customers who initially filed separate lawsuits in various California superior courts. These lawsuits have been pending against other marketers, traders, transporters and sellers of natural gas since as early as 2004, and have been coordinated in the San Diego Superior Court with numerous other natural gas actions under the heading, “In re Natural Gas Anti-Trust Cases I, II, III, IV, and V. Plaintiffs allege that beginning at least by the summer of 2000, defendants, including Enserco, used various practices to manipulate natural gas prices in California in violation of the Xxxxxxxxxx Act and other California state laws. The plaintiffs assert certain wrongful conduct on the part of other defendants which is not asserted against Enserco. They allege manipulation of prices by Enserco through reporting of transactions to industry trade publications. No specific amount of damages is alleged. In January the trial court granted Enserco’s Motion to Dismiss the Complaints based upon the statue of limitations and other defenses, and allowed plaintiffs to file an Amended Complaint against Enserco, which they did on February 5, 2007. Enserco filed a Motion to Dismiss the Amended Complaint on grounds similar to those asserted as to the original Complaint. A hearing on that Motion is set for June 5, 2007, at which time we expect to receive a ruling. If the Motion is denied, Enserco intends to vigorously defend these lawsuits. While the Company cannot predict the final timing or outcome of these actions, they are not expected to have a material impact on the Company’s consolidated financial position or results of operations.

4.	Las Vegas Cogeneration Limited Partnership/Nevada Power Company Arbitration

On March 16, 2007, Nevada Power Company filed a Demand for Arbitration pursuant to a Power Purchase Agreement dated May 27, 1992, (the “Agreement”) between Nevada Power and Las Vegas Cogeneration Limited Partnership (“LVC”). Nevada Power asserts that LVC is in breach of its obligation under the Agreement to maintain a “reliable fuel supply throughout the term of the Power Contract.” Nevada Power also asserts that LVC failed to deliver the amounts of energy and capacity required by the Agreement. The relief Nevada Power requests include: (1) A Determination and Order requiring LVC to provide reasonable assurance of its ability to supply fuel to the facility for the full remaining term of the Agreement; (2) A Determination and Order that LVC has breached the Agreement relating to fuel supply requirements, and therefore finding that Nevada Power is relieved of its obligation to purchase power under the Agreement; (3) A Determination and Order concerning the energy and capacity delivery requirements of the Agreement; and (4) A Determination and Order that LVC breached the performance requirements of the Agreement during the winter season of 2005-2006, and providing an award of damages incurred by Nevada Power by reason of the alleged breach.

LVC denies all these claims and filed its response to the Demand for Arbitration, asserting the following defenses: (1) That Nevada Power failed to honor its contractual obligation to properly negotiate in good faith before filing the demand for arbitration; (2) That LVC has complied with its obligations relating to fuel supply and transportation; (3) That LVC has fulfilled its obligations to deliver energy and capacity to Nevada Power, and did not breach the Agreement during the winter season of 2005-2006, when substantial mechanical problems required an extended outage to perform redesign and repair of generation equipment; (4) That numerous other affirmative defenses preclude Nevada Power from receiving the relief requested.

The arbitration demand was filed with the American Arbitration Association, pursuant to its Commercial Arbitration Rules. The parties are in the process of selecting an arbitrator, who will establish the process and schedule for determination of this dispute. While the Company cannot predict the final timing or outcome of this action, it is not expected to have a material impact on the Company’s consolidated financial position or results of operations.
