The Applicable Commitment Fee Rate and Applicable Margin shall be adjusted ten (10) Business Days after any change in ratings that would require such adjustment. For purposes of this definition, the Levels shall be defined and determined as follows:

Level I shall apply if the Borrower’s Long Term Debt Rating is BBB+ or better (S&P), Baa1 or better (Xxxxx’x) and BBB+ or better (Fitch).

Level II shall apply if the Borrower’s Long Term Debt Rating is BBB (S&P), Baa2 (Xxxxx’x) and BBB (Fitch), but no numerically lower Level applies.

Level III shall apply if the Borrower’s Long Term Debt Rating is BBB- (S&P), Baa3 (Moody’s) and BBB- (Fitch), but no numerically lower Level applies.

ARTICLE II TERMS OF LENDING AND ISSUANCE OF LETTERS OF CREDIT

Section 2.1 The Commitments and the Swing Line Loans. Subject to the terms and conditions hereof and in reliance upon the warranties of the Borrower herein:

(a) Subject to the terms and conditions hereof and in reliance upon the warranties of the Borrower herein, each Bank agrees, severally and not jointly, to make loans (each, a “Revolving Loan” and, collectively, the “Revolving Loans”) to the Borrower from time to time from the date hereof until the Termination Date, during which period the Borrower may repay and reborrow in accordance with the provisions hereof, provided, that the aggregate unpaid principal amount of any Bank’s Revolving Loans, its Percentage of Letter of Credit Obligations and its Percentage of Swing Line Loans shall not exceed such Bank’s Commitment and provided, further, that the total of all outstanding Revolving Loans, Letter of Credit Obligations and Swing Line Loans shall not exceed the aggregate Commitments of all Banks at any time. The Revolving Loans shall be made by the Banks on a pro rata basis, calculated for each Bank based on its Percentage.

(b) Upon request by the Borrower, the Swing Line Bank may, at its sole discretion, make loans (each a “Swing Line Loan” and, collectively, the “Swing Line Loans”) to the

Borrower from time to time from the date hereof until the Termination Date, provided, that the aggregate unpaid principal amount of the Swing Line Loans at any one time outstanding shall not exceed the Swing Line Guideline.

Section 2.2 Advance Options. The Revolving Loans shall be constituted of LIBOR Advances and/or Base Rate Advances, as shall be selected by the Borrower, except as otherwise provided herein. Any combination of types of Advances may be outstanding at the same time, except that the total number of outstanding LIBOR Advances shall not exceed eight (8) at any one time (or such greater number to which the Administrative Agent may from time to time agree). Each LIBOR Advance shall be in a minimum amount of $500,000. Each Base Rate Advance shall be in a minimum amount of $100,000. Swing Line Loans may be in any amount requested by the Borrower.

Section 2.3 Borrowing Procedures.

(a) Request by Borrower. Any request by the Borrower for a Loan shall be in writing, or by telephone promptly confirmed in writing, and must be given so as to be received by the Agent not later than:

(i) 1:00 p.m., Minneapolis time, on the date of the requested Loan, if the Loan shall be comprised of Base Rate Advances; or

(ii) 12:00 noon, Minneapolis time, three Business days prior to the date of the requested Revolving Loan, if the Revolving Loan shall be, or shall include, a LIBOR Advance.

Each request for a Loan shall specify (1) the borrowing date (which shall be a Business Day), (2) the amount of such Loan and the type or types of Advances comprising such Loan, and (3) if such Loan shall include LIBOR Advances, the initial Interest Periods for such Advances. The Swing Line Bank and the Borrower shall, from time to time, enter into mutually acceptable arrangements for requests for Swing Line Loans.

(b) Funding of Agent. The Agent shall promptly notify each other Bank of the receipt of such request, the matters specified therein, and of such Bank’s Percentage of the requested Revolving Loans. On the date of the requested Revolving Loans, each Bank shall provide its share of the requested Revolving Loans to the Agent in immediately available funds not later than 3:00 p.m., Minneapolis time. On the date of any requested Swing Line Loans, the Swing Line Bank shall provide the requested Swing Line Loan to the Agent in immediately available funds not later than 4:00 p.m., Minneapolis time. Unless the Agent determines that any applicable condition specified in Article VI has not been satisfied, the Agent will make the requested Loans available to the Borrower at the Agent’s principal office in Minneapolis, Minnesota in immediately available funds not later than 5:00 p.m. (Minneapolis time) on the lending date so requested, provided that the Agent shall not be required to make any amount of the requested Revolving Loans available to the Borrower unless the Agent shall have received such amount from the Banks, and provided, further, that unless the Agent shall have been notified in writing by a Bank prior to the time requested Revolving Loans shall be made hereunder that such

Bank does not intend to make its Percentage share of the requested Revolving Loans available to the Agent, the Agent may assume that such Bank has made such Percentage share available to the Agent and the Agent may in reliance on such assumption make Revolving Loans available to the Borrower a corresponding amount. In any case that the Agent has made a Revolving Loan to the Borrower on behalf of a Bank but has not received the amount of such Revolving Loan from such Bank by the time herein required, such Bank shall pay interest to the Agent on the amount so advanced at the overnight Federal Funds rate from the date of such Revolving Loan to the date funds are received by the Agent from such Bank, such interest to be payable with such remittance from such Bank of the principal amount of such Revolving Loan. If the Agent does not receive payment from such Bank by the next Business Day after the date of any Revolving Loan, the Agent shall be entitled to recover such Revolving Loan, with interest thereon at the rate then applicable to the such Revolving Loan, on demand, from the Borrower, without prejudice to the Agent’s and the Borrower’s rights against such Bank. If such Bank pays the Agent the amount herein required with interest at the overnight rate before the Agent has recovered from the Borrower, such Bank shall be entitled to the interest payable by the Borrower with respect to the Revolving Loan in question accruing from the date the Agent made such Revolving Loan.

Section 2.4 Continuation or Conversion of Loans. The Borrower may elect to (i) continue any outstanding LIBOR Advance from one Interest Period into a subsequent Interest Period to begin on the last day of the earlier Interest Period, or (ii) convert any outstanding Advance into another type of Advance (on the last day of an Interest Period only, in the instance of a LIBOR Advance), by giving the Agent notice in writing, or by telephone promptly confirmed in writing, given so as to be received by the Agent not later than:

(a) 1:00 p.m., Minneapolis time, on the date of the requested continuation or conversion, if the continuing or converted Advance shall be a Base Rate Advance; or

(b) 12:00 noon, Minneapolis time, three Business days prior to the date of the requested continuation or conversion, if the continuing or converted Advance shall be a LIBOR Advance.

Each notice of continuation or conversion of an Advance shall specify (i) the effective date of the continuation or conversion (which shall be a Business Day), (ii) the amount and the type or types of Advances following such continuation or conversion (subject to the limitation on amount set forth in Section 2.2), and (iii) for continuation as, or conversion into, LIBOR Advances, the Interest Periods for such Advances. Absent timely notice of continuation or conversion, following expiration of an Interest Period unless the LIBOR Advance is paid in full, the Agent may at any time thereafter convert the LIBOR Advance into a Base Rate Advance. Until such time as such Advance is converted into a Base Rate Advance by the Agent or the Borrower or is continued as a LIBOR Advance with a new Interest Period by notice by the Borrower as provided above, such Advance shall continue to accrue interest at a rate equal to the interest rate applicable during the expired Interest Period adjusted, however, to reflect changes in the Applicable Margin. No Advance shall be continued as, or converted into, a LIBOR Advance if the shortest Interest Period for such Advance may not transpire prior to the Termination Date or

if a Default or Event of Default shall exist and the Agent has given notice to the Borrower that no such continuations or conversions may be made.

Section 2.5 Evidence of Indebtedness.

(a) Each Bank and the Swing Line Bank shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Bank resulting from each Loan made by such Bank or Swing Line Bank, including the amounts of principal and interest payable and paid to such Bank or Swing Lien Bank from time to time hereunder.

(b) The Agent, acting for this purpose as an agent of the Borrower, shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Bank and the Swing Line Bank hereunder and (iii) the amount of any sum received by the Agent hereunder for the account of the Banks and the Swing Line Bank and each Bank’s and Swing Line Bank’s share thereof (the “Register”).

(c) The entries made in the accounts maintained pursuant to paragraph (a) or (b) of this Section 2.5 shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Bank, the Swing Line Bank or the Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement. The Borrower, the 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 or any Bank, at any reasonable time and from time to time upon reasonable prior notice.

(d) Any Bank or the Swing Line Bank may request that Loans made by it be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Bank or Swing Line Bank a Revolving Note payable to such Bank and its registered assigns or a Swing Line Note payable to the Swing Line Bank and its registered assigns.

Section 2.6 Funding Losses. In the event of (a) any failure of the Borrower to borrow, continue or convert a LIBOR Advance on a date specified in a notice thereof, or (b) any payment (including, without limitation, any payment pursuant to Section 4.2, 4.3 or 10.2), prepayment or conversion of any LIBOR Advance on a date other than the last day of the Interest Period for such Advance, the Borrower agrees to pay each Bank’s costs, expenses and Interest Differential (as determined by such Bank) incurred as a result of such event. The term “Interest Differential” shall mean that sum amount, not less than $0, equal to the financial loss incurred by each Bank resulting from such event, calculated as the difference between the amount of interest such Bank would have earned (from like investments in the Money Markets as of the first day of the Interest Period of the relevant Advance) had such event not occurred and the interest the Bank will actually earn (from like investments in the Money Markets as of the date of such event) as a result of the redeployment of funds from such event. Because of the short-term nature of this

facility, the Borrower agrees that the Interest Differential shall not be discounted to its present value. The term “Money Markets” refers to one or more wholesale funding markets available to the Banks, including negotiable certificates of deposit, commercial paper, LIBOR deposits, bank notes, federal funds and others. Such determinations by each Bank of shall be conclusive in the absence of manifest error.

Section 2.7 Refunding of Swing Line Loans.

(a) At any time permitted hereunder, the Borrower may request the Banks to make Revolving Loans which may be applied to repay the Swing Line Loans outstanding. Upon occurrence and during continuance of a Default or Event of Default, the Swing Line Bank may, on behalf of the Borrower (which hereby irrevocably directs the Swing Line Bank to act on its behalf), upon notice given by the Swing Line Bank no later than 12:00 noon, Minneapolis time, on the relevant refunding date, request each Bank to make, and each Bank hereby agrees to make, a Revolving Loan (which shall be a Base Rate Advance), in an amount equal to such Bank’s Percentage of the aggregate amount of the Swing Line Loans (the “Refunded Swing Line Loans”) outstanding on the date of such notice, to refund such Swing Line Loans. Each Bank shall make the amount of such Revolving Loan available to the Agent in immediately available funds, no later than 2:00 p.m., Minneapolis time, on the date of such notice. The proceeds of such Revolving Loans shall be distributed by the Agent to the Swing Line Bank and immediately applied by the Swing Line Bank to repay the Refunded Swing Line Loans.

(b) If, for any reason, Revolving Loans may not be (as determined by the Agent in its sole discretion), or are not, made pursuant to Section 2.7(a) to repay Swing Line Loans, then, effective on the date such Revolving Loans would otherwise have been made, each Bank severally, unconditionally and irrevocably agrees that it shall purchase a participating interest in such Swing Line Loans (“Unrefunded Swing Line Loans”) in an amount equal to the amount of Revolving Loans which would otherwise have been made by such Bank pursuant to Section 2.7(a). Each Bank will immediately transfer to the Agent, in immediately available funds, the amount of its participation (the “Swing Line Participation Amount”), and the proceeds of such participation shall be distributed by the Agent to the Swing Line Bank in such amount as will reduce the amount of the participating interest retained by the Swing Line Bank in its Swing Line Loans.

(c) Whenever, at any time after the Swing Line Bank has received from any Bank such Bank’s Swing Line Participation Amount, the Swing Line Bank receives any payment on account of the Swing Line Loans, the Swing Line Bank will distribute to such Bank its Swing Line Participation Amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Bank’s participating interest was outstanding and funded and, in the case of principal and interest payments, to reflect such Bank’s pro rata portion of such payment if such payment is not sufficient to pay the principal of and interest on all Swing Line Loans then due); provided, however, that in the event that such payment received by the Swing Line Bank is required to be returned, such Bank will return to the Swing Line Bank any portion thereof previously distributed to it by the Swing Line Bank.

(d) Each Bank’s obligation to make the Loans referred to in Section 2.7(a) and to purchase participating interests pursuant to Section 2.7(b) shall be absolute and unconditional and shall not be affected by any circumstance, including, without limitation, (i) any setoff, counterclaim, recoupment, defense or other right which such Bank or the Borrower may have against the Swing Line Bank, the Borrower or any other Person for any reason whatsoever; (ii) the occurrence and continuance of a Default or an Event of Default or the failure to satisfy any of the other conditions precedent specified in Article VI; (iii) any adverse change in the condition (financial or otherwise) of the Borrower; (iv) any breach of this Agreement or any other Loan Document by the Borrower or any Bank; or (v) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing.

Section 2.8 Letters of Credit.

(a) Letters of Credit. Subject to the terms and conditions of this Agreement, and on the condition that aggregate Letter of Credit Obligations shall never exceed the lesser of (i) $50,000,000 or (ii) the Commitments, and that the sum of Letter of Credit Obligations plus Loans shall never exceed the aggregate Commitments of all Banks, the Agent agrees to issue letters of credit for the account of the Borrower or any Subsidiary, as provided in Section 2.8(f), upon request by the Borrower to the Agent (such letters of credit as any of them may be amended, supplemented, extended or confirmed from time to time, along with letters of credit issued under the Existing Credit Agreement, being herein collectively called the “Letters of Credit”). No Letter of Credit shall expire later than the earlier to occur of (x) the fifth Business Day prior to the Termination Date and (y) one year after its issuance, provided that, that Letters of Credit may automatically extend absent notice of termination by the Agent; provided, further, that the expiry date of a Letter of Credit may be later than the fifth Business Day prior to the Termination Date if the Borrower has, on or before the fifth Business Day prior to the Termination Date, (i) posted cash collateral to the Agent on terms satisfactory to the Agent in an amount equal to 105% of the Letter of Credit Obligations with respect to such Letter of Credit to be held and applied in accordance with the terms of Section 10.3, (ii) delivered to the Agent a backstop letter of credit issued by a financial institution reasonably satisfactory to the Agent, or (iii) otherwise entered into an alternative arrangement reasonably satisfactory to the Agent with respect to such Letter of Credit. Upon the date of the issuance of a Letter of Credit, the Agent shall be deemed, without further action by any party hereto, to have sold to each Bank, and each Bank shall be deemed without further action by any party hereto, to have purchased from the Agent, a participation, in its Percentage, in such Letter of Credit and the related Letter of Credit Obligations.

(b) Purchase Unconditional. Each Bank’s purchase of a participating interest in a Letter of Credit pursuant to Section 2.8(a) shall be absolute and unconditional and shall not be affected by any circumstance, including, without limitation, (i) any setoff, counterclaim, recoupment, defense or other right which such Bank or the Borrower may have against the Agent, the Borrower or any other Person for any reason whatsoever; (ii) the occurrence or continuance of a Default or an Event of Default or the failure to satisfy any of the other conditions precedent in Article VI; (iii) any adverse change in the condition (financial or otherwise) of the Borrower; (iv) any breach of this Agreement or any other

Loan Document by the Borrower or any Bank; (v) the expiry date of any Letter of Credit occurring after such Bank’s Commitment has terminated; or (vi) any other circumstance, happening or event whatsoever, whether or not similar or any of the foregoing.

(i) Upon receipt of any request for a Letter of Credit, the Agent shall notify each Bank of the contents of such request and of such Bank’s Percentage of the amount of such proposed Letter of Credit.

(ii) No Letter of Credit may be issued if after giving effect thereto the Letter of Credit Obligations shall exceed $50,000,000 or if the sum of (A) the aggregate outstanding principal amount of Loans plus (B) the aggregate Letter of Credit Obligations would exceed the aggregate Commitments of all Banks. The Commitment of each Bank shall be deemed to be utilized for all purposes hereof in an amount equal to such Bank’s Percentage of the Letter of Credit Obligations.

(iii) Upon receipt from the beneficiary of any Letter of Credit of any demand for payment thereunder, Agent shall promptly notify the Borrower and each Bank as to the amount to be paid as a result of such demand and the payment date. If at any time the Agent shall have made a payment to a beneficiary of such Letter of Credit in respect of a drawing or in respect of an acceptance created in connection with a drawing under such Letter of Credit, each Bank will pay to Agent immediately upon demand by the Agent at any time during the period commencing after such payment until reimbursement thereof in full by the Borrower, an amount equal to such Bank’s Percentage of such payment, together with interest on such amount for each day from the date of demand for such payment (or, if such demand is made after 2:00 p.m. Minneapolis time on such date, from the next succeeding Business Day) to the date of payment by such Bank of such amount at a rate of interest per annum equal to the Federal Funds Effective Rate for such period.

(iv) The Borrower shall be irrevocably and unconditionally obligated forthwith to reimburse the Agent for any amount paid by the Agent upon any drawing under any Letter of Credit, without presentment, demand, protest or other formalities of any kind, all of which are hereby waived; provided that this paragraph shall not relieve the Agent or any Bank of any liability resulting from the gross negligence, bad faith or willful misconduct of the Agent or such Bank, or otherwise affect any defense or other right that the Borrower may have as a result of such gross negligence, bad faith or willful misconduct. Such reimbursement may, subject to satisfaction of the conditions in Article VI and to the available Commitment (after adjustment in the same to reflect the elimination of the corresponding Letter of Credit Obligation), be made by the borrowing of Loans. The Agent will pay to each Bank such Bank’s Percentage of all amounts received from the Borrower for application in payment, in whole or in part, of a Letter of Credit Obligation, but

only to the extent such Bank has made payment to the Agent in respect of such Letter of Credit pursuant to clause (iii) above.

(v) The Borrower’s obligation to reimburse the Agent for any amount paid by the Agent upon any drawing under any Letter of Credit shall be performed strictly in accordance with the terms of this Agreement and the applicable Letter of Credit Agreement under any and all circumstances whatsoever and irrespective of (A) any lack of validity or enforceability of any Letter of Credit, any Letter of Credit Agreement or this Agreement, or any term or provision therein, (B) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent, or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (C) payment by the Agent under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit, or (D) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this clause (v), constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Agent nor the Bank shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Agent; provided that the foregoing shall not be construed to excuse the Agent from liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by the Agent’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence, bad faith or willful misconduct on the part of the Agent (as finally determined by a court of competent jurisdiction), the Agent shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties hereto expressly agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of the Letter of Credit, the Agent may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(vi) The Borrower will pay to Agent for the account of each Bank (subject to Section 2.11 with respect to any Defaulting Bank) in accordance with its Percentage a letter of credit fee with respect to each Letter of Credit equal to an amount, calculated on the basis of daily amount available to be drawn on each Letter of Credit from time to time, in each case for the period from and including

the date of issuance of such Letter of Credit to and including the date of expiration or termination thereof at a per annum rate equal to the then-applicable Applicable Margin for LIBOR Advances, such fee to be due and payable quarterly, in arrears on the Payment Dates. The Agent will pay to each Bank (subject to Section 2.11 with respect to any Defaulting Bank), promptly after receiving any payment in respect of letter of credit fee referred to in this clause (vi), an amount equal to the product of such Bank’s Percentage times the amount of such fees. The Borrower shall also pay to Agent at the Principal Office for the account of the Agent a fronting fee of 0.25% of the face amount of the applicable Letter of Credit. At all times that the rate of interest provided in Section 3.1(d) shall apply to the Loans, the fee paid for the account of the Banks under this Section shall be increased by 2.00% per annum. All fees hereunder shall be computed on the basis of a year of 360 days and paid for the actual number of days elapsed.

(vii) The issuance by the Agent of each Letter of Credit shall be subject to the conditions precedent that the Borrower shall have executed and delivered such applications and other customary instruments and agreements relating to such Letter of Credit as the Agent shall have reasonably requested and are not inconsistent with the terms of this Agreement (the “Letter of Credit Agreements”). In the event of a conflict between the terms of this Agreement and the terms of any Letter of Credit Agreement (including the charging of any fees other than normal and customary reimbursable expenses), the terms hereof shall control.

(viii) In the event that any Letter of Credit remains outstanding after the Termination Date, the Borrower shall deliver, prior to the Termination Date, cash collateral to be held and applied in accordance with the terms of Section 10.3, or a backstop letter of credit issued by a financial institution reasonably satisfactory to the Agent, or otherwise entered into an alternative arrangement reasonably satisfactory to the Agent with respect to any outstanding Letters of Credit.

(d) Indemnification; Release. The Borrower hereby indemnifies and holds harmless the Agent and each Bank from and against any and all claims and damages, losses, liabilities, costs or expenses which the Agent or such Bank may incur (or which may be claimed against the Agent or such Bank by any Person whatsoever), regardless of whether caused in whole or in part by the negligence of any of the indemnified parties, in connection with the execution and delivery of any Letter of Credit or transfer of or payment or failure to pay under any Letter of Credit; provided that the Borrower shall not be required to indemnify any party seeking indemnification for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the extent, caused by (i) the gross negligence, bad faith or willful misconduct of the party seeking indemnification, or (ii) by the failure by the party seeking indemnification to pay under any Letter of Credit after the presentation to it of a request required to be paid under applicable law.

(e) Existing Letters of Credit. Letters of Credit previously issued by the Agent under the Existing Credit Agreement shall be deemed to be “Letters of Credit” for all purposes hereunder.

(f) Issuance of Letters of Credit for Account of Subsidiaries. Upon request of the Borrower, Letters of Credit may be issued for the account of Subsidiaries of the Borrower. In such event, the Borrower shall be deemed to have irrevocably guarantied payment of the obligations of each Subsidiary in respect of Letters of Credit issued for the account of such Subsidiary, and if requested by the Bank, the Borrower shall, together with such Subsidiary, enter into the Letter of Credit Agreement as co-applicant or guarantor, and shall execute and deliver such other instrument of guaranty as shall be required by the Agent.

Section 2.9 Increase to Commitments. The Borrower may, on up to two occasions, increase the Commitments hereunder, by giving notice to the Agent, specifying the dollar amount of the increase (which shall be in a minimum amount of $10,000,000 plus integral multiples of $5,000,000, and which shall not result in total aggregate Commitments hereunder in excess of $250,000,000); provided, however, that an increase in the Commitments hereunder may only be made at a time when no Default or Event of Default shall have occurred and be continuing. The Borrower may increase the Commitments by either increasing a Commitment with an existing Bank or obtaining a Commitment from a new financial institution, the selection of which shall require the consent of the Agent, not to be unreasonably withheld or delayed. The Borrower, the Agent and each Bank or other financial institution that is increasing its Commitment or extending a new Commitment shall enter into an amendment to this Agreement setting forth the amounts of the Commitments, as so increased, providing that any new financial institution extending a new Commitment shall be a Bank for all purposes under this Agreement and effecting such other changes as the Borrower and the Agent shall deem necessary or advisable in connection with such increase of the Commitments hereunder. No such amendment shall require the approval or consent of any Bank whose Commitment is not being increased and no Bank shall be required to increase its Commitment unless it shall so agree in writing. Upon the execution and delivery of such amendment as provided above, this Agreement shall be deemed to be amended accordingly and the Agent shall adjust the funded amount of the Advances of the Banks so that each Bank (including the Banks with new or increased Commitments) shall hold their respective Percentages (as amended by such amendment) of the Advances outstanding and the unfunded Commitments (and each Bank shall so fund any increased amount of Advances).

Section 2.10 Purpose of the Loans. The Loans shall be used (a) to refinance certain indebtedness of the Borrower, and (b) for purposes of funding working capital, capital expenditures, and other corporate purposes of the Borrower and its Subsidiaries.

Section 2.11 Defaulting Banks. Notwithstanding any provision of this Agreement to the contrary, if any Bank becomes a Defaulting Bank, then the following provisions shall apply for so long as such Bank is a Defaulting Bank (the “Default Period”):

(a) Commitment Fees. Such Defaulting Bank’s Commitment, outstanding Loans and Participation Interests shall be excluded for purposes of calculating the Commitment Fees

and Letter of Credit commissions payable to Banks, and such Defaulting Bank shall not be entitled to receive any Commitment Fee or Letter of Credit commission pursuant to Section 3.2 and Section 2.8(c)(vi), respectively, with respect to such Defaulting Bank’s Commitment and such fees with respect to such Defaulting Bank shall cease to accrue.

(b) Voting. Such Defaulting Bank shall be deemed not to be a “Bank” for purposes of voting on any matters and the Commitment, outstanding Loans and Participation Interests of such Defaulting Bank shall not be included in determining whether all Banks or the Required Banks have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 12.2).

(c) Prepayments. To the extent permitted by applicable law, until the end of the Default Period, any voluntary prepayment of the Loans shall, if Borrower so directs at the time of making such voluntary prepayment, be applied to the Loans of other Banks as if such Defaulting Bank had no Loans outstanding.

(d) Reallocation of Swing Line Loans and Letters of Credit. If any Swing Line Loans or Letters of Credit are outstanding at the time a Bank becomes a Defaulting Bank then:

(i) all or any part of such Defaulting Bank’s Participation Interests in such Swing Line Loans or Letters of Credit shall be reallocated among the non-Defaulting Banks in accordance with their respective Percentages but only to the extent (x) the sum of all non-Defaulting Banks’ Loans and Participation Interests plus such Defaulting Bank’s Loans and Participation Interests does not exceed the total of all non-Defaulting Banks’ Commitments and (y) the conditions set forth in Article VI are satisfied at such time; and

(ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrower shall within three (3) Business Days following notice by the Agent prepay such Defaulting Bank’s portion of the Swing Line Loans, or deliver collateral for such Defaulting Bank’s portion of drawings under Letters of Credit to be held as provided in Section 10.3 (to the extent not fully reallocated as provided in clause (i) above after giving effect to any partial reallocation thereunder), or enter into an alternative arrangement satisfactory to the Agent with respect to such Defaulting Bank’s portion of the Swing Line Loans or Letters of Credit.

(e) Application of Payments. Subject to application of voluntary prepayments as described in Section 2.11(c), any amount otherwise payable to a Defaulting Bank hereunder (whether on account of principal, interest, fees or otherwise and including any amount that would otherwise be payable to such Defaulting Bank pursuant to Sections 2.7(c), 2.8(c)(iv), 4.1, 4.2, 4.3, 4.4, 4.5 or 10.4) shall, in lieu of being distributed to such Defaulting Bank, be applied by the Agent (i) first, to the payment of any amounts owing by such Defaulting Bank to the Agent hereunder, (ii) second, pro rata, to the payment of any amounts owing by such Defaulting Bank to the Swing Line Bank hereunder, (iii) third, to the funding of any Loan or the funding of any Participation Interest in respect of which such Defaulting Bank has failed to fund its Percentage thereof

as required by this Agreement, as determined by the Agent, (iv) fourth, at the election of the Agent and the Borrower, either to (x) repay Borrower Obligations to the non-Defaulting Banks, in such order of application as the Agent shall designate, or (y) be held on account with the Agent as cash collateral for future funding obligations of the Defaulting Bank under this Agreement, (v) fifth, pro rata, to the payment of any amounts owing to the Borrower or the non-Defaulting Banks as a result of any judgment of a court of competent jurisdiction obtained by the Borrower or any Bank against such Defaulting Bank as a result of such Defaulting Bank’s breach of its obligations under this Agreement and (vi) sixth, to such Defaulting Bank or as otherwise directed by a court of competent jurisdiction.

(f) Remedy by Defaulting Bank. In the event that the Agent, the Borrower and the Swing Line Bank each agrees that a Defaulting Bank has adequately remedied all matters that caused such Bank to be a Defaulting Bank, then the Participation Interests of the Banks shall be readjusted to reflect the inclusion of such Bank’s Commitment and on such date such Bank shall purchase at par such of the Loans of the other Banks (other than Swing Line Loans) as the Agent shall determine may be necessary in order for such Bank to hold such Loans in accordance with its Percentage. In addition, at such time as a Defaulting Bank ceases to be a Defaulting Bank, the Agent shall cause any and all collateral delivered by the Borrower pursuant to Section 2.11(d)(ii) to be promptly released and returned to the Borrower, and there shall be no retroactive adjustment to or accrual of any Commitment Fees or Letter of Credit commissions that would otherwise have been payable to such Defaulting Bank during the Default Period if such Defaulting Bank had not been a Defaulting Bank.

(g) Non-exclusive Remedies. The rights and remedies against a Defaulting Bank under this Section 2.11 are in addition to other rights and remedies which Borrower may have against such Defaulting Bank with respect to any Funding Default and which the Agent or any Bank may have against such Defaulting Bank with respect to any Funding Default.

Section 2.12 Replacement of Banks. If the Agent or a Bank provides the Borrower with a notice pursuant to Section 5.1, 5.2 or 5.3 or if any Bank becomes a Defaulting Bank, then the Borrower may, at its sole expense and effort, upon notice to such Defaulting Bank and the Agent, require such Bank or Defaulting Bank to assign and delegate, without recourse, all of its interests, rights and obligations under this Agreement and the related Loan Documents to an assignee that shall assume such obligations (which assignee may be another Bank, if a Bank accepts such assignment), provided that:

(a) The Borrower shall have paid to the Agent the assignment fee specified in Section 12.3(b)(ii);

(b) Such Defaulting Bank shall have received payment of an amount equal to the outstanding principal of its Loans and its portion of the Swing Line Participation Amount, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts); and

Section 2.13 Authorized Representatives. The Borrower shall act hereunder through the Authorized Representatives designated from time to time and all notices and requests to be given and received by the Borrower, including requests for Loans and designation of amounts of Advances and Interest Periods, shall be given by and directed to such Authorized Representatives.

Section 2.14 Extensions of Commitments.

(a) The Borrower may from time to time, pursuant to the provisions of this Section 2.14, agree with one or more Banks holding Commitments to extend the termination date, and otherwise modify the terms of such Commitments or any portion thereof (including, without limitation, by increasing the interest rate or fees payable in respect of such Commitments or any portion thereof (each, such modification an “Extension”) pursuant to one or more written offers (each, an “Extension Offer”) made from time to time by the Borrower to all Banks, in each case on a pro rata basis (based on their respective Percentages) and on the same terms to each such Bank. In connection with each Extension, the Borrower will provide notification to the Agent (for distribution to the Banks), no later than 60 days prior to the Termination Date of the requested new termination date for the extended Commitments (each an “Extended Termination Date”) and the due date for Bank responses. In connection with any Extension, each Bank wishing to participate in such Extension shall, prior to such due date, provide the Agent with a written notice thereof in a form reasonably satisfactory to the Agent. Any Bank that does not respond to an Extension Offer by the applicable due date shall be deemed to have rejected such Extension.

(b) Each Extension shall be subject to the following:

(i) no Default or Event of Default shall have occurred and be continuing at the time any Extension Offer is delivered to the Banks or at the time of such Extension;

(ii) except as to interest rates, fees, termination date and increase to Commitments under Section 2.9 (which shall, subject to immediately clause (iii) below, be determined by the Borrower and set forth in the relevant Extension Offer), the Commitment of any Bank extended pursuant to any Extension shall have the same terms as the Commitments of the Banks that did not agree to the Extension Offer;

(iii) the final termination date of the Commitments to be extended pursuant to an Extension shall be later than the final termination date of the Commitments of the Banks that did not agree to the Extension Offer;

(iv) if the aggregate amount of Commitments in respect of which Banks shall have accepted an Extension Offer exceeds the maximum aggregate amount of Commitments offered to be extended by the Borrower pursuant to the relevant Extension Offer, then such Commitments shall be extended ratably up to such

maximum amount based on the relative Commitments of the Banks that accepted such Extension Offer;

(v) all documentation in respect of such Extension shall be consistent with the foregoing, and all written communications by the Borrower generally directed to the applicable Banks in connection therewith shall be in form and substance consistent with the foregoing and otherwise reasonably satisfactory to the Agent;

(vi) any applicable Minimum Extension Condition shall be satisfied; and

(vii) no Extension shall become effective unless, on the proposed effective date of such Extension, the conditions set forth in Section 6.2 shall be satisfied (with all references in such Section to a request for a Loan being deemed to be references to the Extension on the applicable date of such Extension), and the Agent shall have received a certificate to that effect dated the applicable date of such Extension and executed by an Authorized Representative of the Borrower.

(c) If at the time any Extension of Commitments (as so extended, “Current Extension Commitments”) becomes effective, there will be Commitments or Revolving Loans attributable to a prior Extension that will remain outstanding (collectively, the “Prior Extension Commitments”), then, if the interest rate spread applicable to any such Current Extension Commitments exceeds the interest rate spread applicable to such Prior Extension Commitments by more than 0.25%, then the interest rate spread applicable to such Prior Extension Commitments shall be increased so that it equals the interest rate spread applicable to the Current Extension Commitments (calculated as provided above).

(d) The consummation and effectiveness of any Extension will be subject to a condition set forth in the relevant Extension Offer (a “Minimum Extension Condition”) that a minimum amount be agreed to by the Banks subject to such Extension (to be determined in the Borrower’s discretion and specified in the relevant Extension Offer, but in no event less than $25,000,000, unless another amount is agreed to by the Agent). For the avoidance of doubt, it is understood and agreed that the provisions of Section 4.5 will not apply to Extensions of Commitments pursuant to Extension Offers made pursuant to and in accordance with the provisions of this Section 2.14, including to any payment of interest or fees in respect of any Commitments or Revolving Loans that have been made extended or made pursuant to an Extension at a rate or rates different from those paid or payable in respect of Commitments or Revolving Loans of Banks that did not extend their Commitments, in each case as is set forth in the relevant Extension Offer.

(e) The Banks hereby irrevocably authorize the Agent to enter into amendments (collectively, “Extension Amendments”) to this Agreement and the other Loan Documents as may be necessary in order establish new classes of Commitments and Revolving Loans created pursuant to an Extension, in each case on terms consistent with this Section 2.14. Notwithstanding the foregoing, the Agent shall have the right (but not the obligation) to seek the advice or concurrence of the Required Banks with respect to any matter contemplated by this Section 2.14 and, if the Agent seeks such advice or concurrence, the Agent shall be permitted to enter into such amendments with the

Borrower in accordance with any instructions received from such Required Banks and shall also be entitled to refrain from entering into such amendments with the Borrower unless and until it shall have received such advice or concurrence; provided, however, that whether or not there has been a request by the Agent for any such advice or concurrence, all such Extension Amendments entered into with the Borrower by the Agent hereunder shall be binding on the Banks. Without limiting the foregoing, in connection with any Extension, the Borrower and any Material Subsidiary shall execute such agreements, confirmations or other documentation as the Agent shall reasonably request to accomplish the purposes of this Section 2.14.

(f) In connection with any Extension, the Borrower shall provide the Agent at least 60 days’ (or such shorter period as may be agreed by the Administrative Agent) prior written notice thereof, and shall agree to such procedures, if any, as may be reasonably established by, or acceptable to, the Agent to accomplish the purposes of this Section 2.14.

Section 2.15 Tax Matters. No Person can become a Bank unless it is either a United States Person or an “exempt recipient” within the meaning of Treasury Regulations Section 1.6049-4(c) based on the indicators set forth therein, unless such Person represents and warrants to the Agent and the Borrower that it is entitled to receive interest payments without withholding or deduction of any taxes and executes and delivers to the Agent and the Borrower a United States Internal Revenue Service Form W8BEN, W8ECI, W-8 IMY and/or W-9 or any successor to either of such forms, as appropriate, properly completed a claiming complete exemption from withholding and deduction of all Federal Income Taxes. A “United States Person” means any citizen, national or resident of the United States, any corporation or other entity created or organized in or under the laws of the United States or any political subdivision hereof or any estate or trust, in each case that is not subject to withholding of United States Federal income taxes or other taxes on payment of interest, principal of fees hereunder.

ARTICLE III INTEREST AND FEES

a rate per annum equal to the greater of (i) 2.00% in excess of the rate applicable to the unpaid principal amount immediately before it became due, or (ii) 2.00% in excess of the Base Rate in effect from time to time.

Section 3.2 Commitment Fee. The Borrower shall (subject to Section 2.11 with respect to any Defaulting Bank) pay fees (the “Commitment Fees”) to the Agent for the account of the Banks (in according with their respective Percentages) in an amount determined by applying the Applicable Commitment Fee Rate per annum to the average daily unused amount of the Commitments (with the face amount of all Letters of Credit deemed usage for such purpose, but Swing Line Loans not deemed usage) of the Banks for the period from the date hereof to the Termination Date.

ARTICLE IV PAYMENTS, PREPAYMENTS, REDUCTION OR TERMINATION
OF THE CREDIT AND SETOFF

Section 4.1 Repayment. Principal of the Loans, together with all accrued and unpaid interest thereon, shall be due and payable on the Termination Date.

Section 4.2 Optional Prepayments. The Borrower may, upon at least one (1) Business Day’s (in the case of Base Rate Advances, or three (3) Business Days’ in the case of LIBOR Advances) prior written or telephonic notice received by the Bank, prepay the Loans, in whole or in part, at any time subject to the provisions of Section 2.6, without any other premium or penalty. In the event that the Loans are being refinanced, any such notice may be made contingent upon the closing of such refinancing. Any such prepayment must be accompanied by accrued and unpaid interest on the amount prepaid. Each partial prepayment shall be in an amount of $50,000 or an integral multiple thereof. Any prepayment of a LIBOR Advance shall be in an amount equal to the remaining entire principal balance of such Advance. In the event that the Loans are being refinanced, any such notice may be made contingent upon the closing of such refinancing.

Section 4.3 Optional Reduction or Termination of Commitment. The Borrower may, at any time, upon no less than one (1) Business Day prior written or telephonic notice received by the Agent, reduce the Commitment, with any such reduction in a minimum amount of $500,000 or an integral multiple thereof. In the event that the Loans are being refinanced, any such notice may be made contingent upon the closing of such refinancing. Upon any reduction in the Commitment pursuant to this Section, the Borrower shall pay to the Agent for the account of the

Banks the amount, if any, by which the aggregate unpaid principal amount of outstanding Loans plus the Letter of Credit Obligations exceeds the Commitment as so reduced. Amounts so paid cannot be reborrowed. The Borrower may, at any time, upon not less than one (1) Business Day prior written notice to the Agent, terminate the Commitment in its entirety. Upon termination of the Commitment pursuant to this Section, the Borrower shall pay to the Agent for the account of the Banks the full amount of all outstanding Loans, all accrued and unpaid interest thereon, all unpaid Commitment Fees accrued to the date of such termination and all other unpaid obligations of the Borrower to the Banks hereunder. All payment described in this Section is subject to the provisions of Section 2.6. Notwithstanding the foregoing, the Commitment may not be reduced to an amount below outstanding Letter of Credit Obligations, or terminated if Letters of Credit are outstanding (unless the Borrower has provided cash collateral or a backstop letter of credit issued by a financial institution reasonably satisfactory to the Agent, or otherwise entered into an alternative arrangement reasonably satisfactory to the Agent with respect to any outstanding Letters of Credit).

Section 4.4 Payments. Payments and prepayments of principal of, and interest on, the Notes and all fees, expenses and other obligations under the Loan Documents shall be made (subject only to required withholding by the Borrower in the case of non-compliance by a Bank with the requirements of Section 12.3(e)) without set-off or counterclaim in immediately available funds not later than 2:00 p.m., Minneapolis time, on the dates due at the main office of the Agent in Minneapolis, Minnesota, provided, however, that the Swing Line Bank and the Borrower shall enter into mutually acceptable arrangements for payment of the Swing Line Loans which may permit payment of the Swing Line Loans later than such time. Funds received on any day after such time shall be deemed to have been received on the next Business Day. The Agent shall promptly distribute in like funds to each Bank its Percentage share of each such payment of principal, interest and Commitment Fees. Subject to the definition of the term “Interest Period”, whenever any payment to be made hereunder or on the Notes shall be stated to be due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and such extension of time shall be included in the computation of any interest or fees. The Agent is authorized to debit the operating account of the Borrower designated by the Borrower for such purpose from time to time for all payments when due hereunder (provided that if such account shall not have sufficient available funds to pay interest when due, the Borrower shall pay such interest in immediately available funds).

Section 4.5 Proration of Payments. If any Bank or other holder of a Loan shall obtain any payment or other recovery (whether voluntary, involuntary, by application of offset, pursuant to the Material Subsidiary Guaranties or otherwise) on account of principal of, interest on, or fees with respect to any Loan, or payment of any Letter of Credit Obligations, in any case in excess of the share of payments and other recoveries of other Banks or holders, such Bank or other holder shall purchase from the other Banks or holders, in a manner to be specified by the Agent, such participations in the Loans held by such other Banks or holders as shall be necessary to cause such purchasing Bank or other holder to share the excess payment or other recovery ratably with each of such other Banks or holders; provided, however, that if all or any portion of the excess payment or other recovery is thereafter recovered from such purchasing Bank or holder, the purchase shall be rescinded and the purchase price restored to the extent of such recovery, but without interest.

ARTICLE V ADDITIONAL PROVISIONS RELATING TO LOANS

Section 5.1 Increased Costs. If, as a result of any change after the date hereof of any law, rule, regulation, treaty or directive or in the interpretation or administration thereof, or compliance by the Banks with any request or directive (whether or not having the force of law) from any court, central bank, governmental authority, agency or instrumentality, or comparable agency:

(a) any tax, duty or other charge with respect to any Loan, the Notes or the Commitments is imposed, modified or deemed applicable, or the basis of taxation of payments to any Bank of interest or principal of the Loans or of the Commitment Fees (other than taxes imposed on the overall net income of such Bank by the jurisdiction in which such Bank has its principal office) is changed;

(b) any reserve, special deposit, special assessment or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Bank (excluding any reserve or other requirement reflected in the calculation of LIBOR Rate (Reserve Adjusted)) is imposed, modified or deemed applicable;

(c) any increase in the amount of capital required or expected to be maintained by any Bank or any Person controlling such Bank is imposed, modified or deemed applicable as a consequence of this Agreement or the Loans made by such Bank; or

(d) any other condition (other than any condition relating to taxes, duties, or other charges as set forth in clause (a) above) affecting this Agreement or the Commitments is imposed on any Bank or the relevant funding markets;

and such Bank determines that, by reason thereof, the cost to such Bank of making or maintaining the Loans, issuing or participating in the Letters of Credit or extending its Commitment is increased, or the amount of any sum receivable by such Bank hereunder or under the Notes in respect of any Loan is reduced to a level below which such Bank could have achieved but for such change (taking into consideration such Bank’s policies with respect to capital adequacy);

then, the Borrower shall pay to such Bank upon demand such additional amount or amounts as will compensate such Bank (or the controlling Person in the instance of (c) above) for such additional costs or reduction (provided that the Banks have not been compensated for such additional cost or reduction in the calculation of the LIBOR Reserve Rate). Any Bank making such demand shall inform the Borrower of the basis for such demand, and provide a statement showing, in reasonable detail, calculation of the amount demanded. The Borrower will promptly notify such Bank if the Borrower does not agree to such Bank’s determination of any such amount. Any Bank’s reasonable determination of such amount shall be presumed correct, absent its manifest error or negligence in determining such amounts. In determining such amounts, the Banks may use any reasonable averaging, attribution and allocation methods. Notwithstanding the foregoing, no Bank shall charge the Borrower for additional amounts for such additional costs or reductions: (i) which additional amounts applied or accrued more than 90 days prior to the time that such Bank became aware of the event giving rise to such additional costs or

reductions; or (ii) unless such Bank is generally requiring payment under comparable provisions of its agreements with similarly situated borrowers.

Section 5.2 Deposits Unavailable or Interest Rate Unascertainable or Inadequate; Impracticability. If the Agent determines (which determination shall be conclusive and binding on the parties hereto), or in the case of Section 5.2(b), the Agent or the Required Banks determine, that:

(a) deposits of the necessary amount for the relevant Interest Period for any LIBOR Advance are not available in the relevant markets or that, by reason of circumstances affecting such market, adequate and reasonable means do not exist for ascertaining the LIBOR Interbank Rate for such Interest Period; or

(b) that the LIBOR Rate (Reserve Adjusted) will not adequately and fairly reflect the cost to the Banks of making, maintaining or funding the LIBOR Advance for a relevant Interest Period;

the Agent shall promptly give notice of such determination to the Borrower, and (i) any notice of a new LIBOR Advance previously given by the Borrower and not yet borrowed or converted shall be deemed to be a notice to make a Base Rate Advance, and (ii) the Borrower shall be obligated to either prepay in full any outstanding LIBOR Advances or convert any such LIBOR Advance to a Base Rate Advance, without premium or penalty on the last day of the current Interest Period with respect thereto.

Section 5.3 Changes in Law Rendering LIBOR Advances Unlawful. If at any time due to the adoption of any law, rule, regulation, treaty or directive, or any change therein or in the interpretation or administration thereof by any court, central bank, governmental authority, agency or instrumentality, or comparable agency charged with the interpretation or administration thereof, or for any other reason arising subsequent to the date of this Agreement, it shall become unlawful or impossible for any Bank to make or fund any LIBOR Advance, the obligation of such Bank to provide such Advance shall, upon the happening of such event, forthwith be suspended for the duration of such illegality or impossibility. If any such event shall make it unlawful or impossible for the Bank to continue any LIBOR Advance previously made by it hereunder, such Bank shall, upon the happening of such event, notify the Agent and the Borrower thereof in writing, and the Borrower shall, at the time notified by such Bank, either convert each such unlawful Advance to a Base Rate Advance or repay such Advance in full, together with accrued interest thereon, subject to the provisions of Section 2.6.

Section 5.4 Discretion of the Banks as to Manner of Funding. Notwithstanding any provision of this Agreement to the contrary, each Bank shall be entitled to fund and maintain its funding of all or any part of the Loans in any manner it elects; it being understood, however, that for purposes of this Agreement, all determinations hereunder shall be made as if the Banks had actually funded and maintained each LIBOR Advance during the Interest Period for such Advance through the purchase of deposits having a term corresponding to such Interest Period and bearing an interest rate equal to the LIBOR Interbank Rate for such Interest Period (whether or not any Bank shall have granted any participations in such Advances).

ARTICLE VII REPRESENTATIONS AND WARRANTIES

To induce the Agent and the Banks to enter into this Agreement, to grant the Commitments and to make Loans hereunder, the Borrower represents and warrants to the Agent and the Banks:

Section 7.1 Organization, Standing, Etc. The Borrower and each of its corporate Material Subsidiaries are corporations duly incorporated and validly existing and in good standing under the laws of the jurisdiction of their respective incorporation and have all requisite corporate power and authority to carry on their respective businesses as now conducted, to (in the instance of the Borrower) enter into the Loan Documents and to perform its obligations under the Loan Documents. The Borrower and each of the Material Subsidiaries are duly qualified and in good standing as a foreign corporation in each jurisdiction in which the character of the properties owned, leased or operated by it or the business conducted by it makes such qualification necessary, and failure to so qualify or remain in good standing would constitute an Adverse Event.

Section 7.2 Authorization and Validity. The execution, delivery and performance by the Borrower of the Loan Documents have been duly authorized by all necessary corporate action by the Borrower, and the Loan Documents constitute the legal, valid and binding obligations of the Borrower, enforceable against the Borrower in accordance with their respective terms, subject to limitations as to enforceability which might result from bankruptcy, insolvency, moratorium and other similar laws affecting creditors’ rights generally and subject to limitations on the availability of equitable remedies.

Section 7.3 No Conflict; No Default. The execution, delivery and performance by the Borrower of the Loan Documents will not (a) violate any provision of any law, statute, rule or regulation or any order, writ, judgment, injunction, decree, determination or award of any court, governmental agency or arbitrator presently in effect having applicability to the Borrower, (b) violate or contravene any provisions of the Articles (or Certificate) of Incorporation or by-laws of the Borrower, or (c) result in a breach of or constitute a default under any indenture, loan or credit agreement or any other agreement, lease or instrument to which the Borrower is a party or by which it or any of its properties may be bound or result in the creation of any Lien on any asset of the Borrower or any Material Subsidiary, which in any such case under subsection (a) or (c) would reasonably constitute an Adverse Event. Neither the Borrower nor any Material Subsidiary is in default under or in violation of any such law, statute, rule or regulation, order, writ, judgment, injunction, decree, determination or award or any such indenture, loan or credit agreement or other agreement, lease or instrument in any case in which the consequences of such default or violation would constitute an Adverse Event. No Default or Event of Default has occurred and is continuing.

Section 7.4 Government Consent. No order, consent, approval, license, authorization or validation of, or filing, recording or registration with, or exemption by, any governmental or public body or authority is required on the part of the Borrower to authorize, or is required in connection with the execution, delivery and performance of, or the legality, validity, binding effect or enforceability of, the Loan Documents, except for such orders, consents, approvals, licenses, authorizations, validations, filings, recordings, registrations or exemptions as have been made or obtained and are in full force and effect.

Section 7.5 Financial Statements and Condition. The Borrower’s audited consolidated financial statements as of December 31, 2009, and the Borrower’s unaudited quarterly financial statements as at March 31, 2010, as heretofore furnished to the Banks, have been prepared in accordance with GAAP on a consistent basis (except, in the case of the unaudited quarterly financial statements, for the absence of footnotes and for year-end audit adjustments) and fairly present in all material respects the financial condition of the Borrower and the Subsidiaries, taken as a consolidated enterprise, as at such dates and the results of their operations for the fiscal year then ended. As of the dates of such consolidated financial statements, neither the Borrower nor any Material Subsidiary had any material obligation, contingent liability, liability for taxes or long term lease obligation which is not reflected in such consolidated financial statements or in the notes thereto. Since December 31, 2009, no Adverse Event has occurred.

Section 7.6 Litigation and Contingent Liabilities. Except as described in Schedule 7.6, there are no actions, suits or proceedings pending or, to the knowledge of the Borrower, threatened against or affecting the Borrower or any Material Subsidiary or any of their properties before any court or arbitrator, or any governmental department, board, agency or other instrumentality which, if determined adversely to the Borrower or such Material Subsidiary, would constitute an Adverse Event. Except as described in Schedule 7.6, neither the Borrower nor any Material Subsidiary has any contingent liabilities which are material to the Borrower and the Subsidiaries as a consolidated enterprise.

Section 7.7 Compliance. The Borrower and the Material Subsidiaries are in material compliance with all statutes and governmental rules and regulations applicable to them, except where noncompliance thereof would not constitute an Adverse Event.

In the event the Borrower defaults in the payment of any Letter of Credit Obligations, the proceeds of the cash collateral account shall be applied to the payment thereof. The Borrower acknowledges and agrees that the Banks would not have an adequate remedy at law for failure by the Borrower to pay immediately to the Agent the amount provided under this Section, and that the Agent shall, on behalf of the Banks, have the right to require the Borrower to perform specifically such undertaking whether or not any of the Letter of Credit Obligations are due and payable. Upon the failure of the Borrower to make any payment required under this Section, the Agent, on behalf of the Banks, may proceed to use all remedies available at law or equity to enforce the obligation of the Borrower to pay or reimburse the Agent.

Each Bank agrees to promptly notify the Borrower and the Agent after any such setoff and application made by such Bank; provided that the failure to give such notice shall not affect the validity of such setoff and application.

No failure on the part of the Banks or the holder of the Notes to exercise and no delay in exercising any power or right hereunder or under any other Loan Document shall operate as a waiver thereof; nor shall any single or partial exercise of any power or right preclude any other or further exercise thereof or the exercise of any other power or right. The remedies herein and in any other instrument, document or agreement delivered or to be delivered to the Banks hereunder or in connection herewith are cumulative and not exclusive of any remedies provided by law. No notice to or demand on the Borrower not required hereunder or under the Notes shall in any event entitle the Borrower to any other or further notice or demand in similar or other circumstances or constitute a waiver of the right of the Banks or the holder of the Notes to any other or further action in any circumstances without notice or demand.

Section 12.2 Amendments, Etc. No amendment or waiver of any provision of this Agreement, nor consent to any departure by the Borrower therefrom, shall in any event be effective unless the same shall be in writing and signed by the Borrower and the Agent upon direction of the Required Banks (subject to Section 2.11 with respect to any Defaulting Bank) and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided that Agent may, with the consent of Borrower only, amend, modify or supplement this Agreement to cure any ambiguity, omission, defect or inconsistency, so long as such amendment, modification or supplement does not materially and adversely affect the rights of any Bank; provided further, however, that no amendment, waiver or consent shall, unless agreed to by the Agent and each of the Banks directly affected thereby (subject to Section 2.11 with respect to any Defaulting Bank):

(a) increase the amounts of or extend the terms of the Commitments of such Bank (it being understood that a waiver or modification of any condition precedent, covenant, Default, Event of Default, mandatory prepayment or mandatory reduction of the Commitments shall not constitute an extension or increase of any Commitment of any Bank);

(c) postpone any date fixed for any payment of principal of, or interest on, the Notes of such Bank, or any fees or other amounts payable hereunder to such Bank;

(a) Assignments. Each Bank shall have the right, subject to the further provisions of this Sections 12.3, to sell or assign all or any part of its Commitments, Loans, Notes, and other rights and obligations under this Agreement and related documents (such transfer, an “Assignment”) to any commercial lender, other financial institution or other entity other than the Borrower or one of its Subsidiaries or affiliates (an “Assignee”). Upon such Assignment becoming effective as provided in Section 12.3(b), the assigning Bank shall be relieved from the portion of its Commitment, obligations to indemnify the Agent and other obligations hereunder to the extent assumed and undertaken by the Assignee, and to such extent the Assignee shall have the rights and obligations of a “Bank” hereunder. Notwithstanding the foregoing, unless otherwise consented to by the Borrower and the Agent, each Assignment shall be in the initial principal amount of not less than $10,000,000 in the aggregate for all Loans and Commitments assigned, or an integral multiple of $1,000,000 if above such amount. Each Assignment shall be documented by an agreement between the assigning Bank and the Assignee (an “Assignment and Assumption Agreement”) substantially in the form of Exhibit E attached hereto.

(b) Effectiveness of Assignments. An Assignment shall become effective hereunder when all of the following shall have occurred: (i) the Agent and the Borrower (or, following occurrence and during continuance of an Event of Default, the Agent only and not the Borrower) shall consent to such Assignment (which consent shall not be unreasonably withheld), by either written notice of such consent or by executing and delivering such Assignments, provided that no such consents shall be required for an assignment to one of the Banks or an affiliate of a Bank or an Approved Fund, (ii) either the assigning Bank or the Assignee shall have paid a processing fee of $3,500 to the

Agent for its own account (unless waived by the Agent), (iii) the Assignee shall have submitted the Assignment and Assumption Agreement to the Agent with a copy for the Borrower, and shall have provided to the Agent information the Agent shall have reasonably requested to make payments to the Assignee, (iv) the assigning Bank and the Agent shall have agreed upon a date upon which the Assignment shall become effective, and (v) the Agent shall have recorded such Assignment in the Register; provided that assignments pursuant to Section 2.12 shall not require the signature or agreement of the assigning Bank to become effective, and any processing fee in connection with such assignments may be paid by the Borrower.

Any assignment or transfer by a Bank of rights or obligations under this Agreement that does not comply with clauses 12.3(a) and (b) 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 Section 12.3(c).

(c) Participations. Each Bank shall have the right, subject to the further provisions of this Section 12.3, to grant or sell a participation in all or any part of its Loans, Notes and Commitments (a “Participation”) to any commercial lender, other financial institution or other entity (a “Participant”) without the consent of the Borrower, the Agent of any other party hereto. The Borrower agrees that if amounts outstanding under this agreement and the Notes are due and unpaid, or shall have been declared or shall have become due and payable upon the occurrence and during the continuance of an Event of Default, each Participant shall be deemed to have the right of setoff in respect of its Participation in amounts owing under this Agreement and any Note to the same extent as if the amount of its Participation were owing directly to it as a Bank under this agreement or any note; provided, that such right of setoff shall be subject to the obligation of such Participant to share with the Banks, and the Banks agree to share with such Participant, as provided in Section 4.5. The Borrower also agrees that each Participant shall be entitled to the benefits of Article V with respect to its Participation, provided, that no Participant shall be entitled to receive any greater amount pursuant to such Sections than the transferor Bank would have been entitled to receive in respect of the amount of the Participation transferred by such transferor Bank to such Participant had no such transfer occurred.

GUARANTY
(Joint and Several)

FOR VALUE RECEIVED and in consideration of entry by the Banks (as defined in the Second Amended and Restated Credit Agreement) and U.S. BANK NATIONAL ASSOCIATION, as agent for the Banks (in such capacity, together with it successors and assigns, called the “Agent”) into that certain Second Amended and Restated Credit Agreement, dated as of May 4, 2010 (as thereafter amended, modified, extended, renewed, restated or replaced from time to time called the “Second Amended and Restated Credit Agreement”) among the Banks, the Agent and OTTER TAIL CORPORATION, a Minnesota corporation (hereinafter called the “Debtor”), the undersigned corporations (the “Guarantors”) hereby JOINTLY AND SEVERALLY unconditionally guarantee the full and prompt payment when due, whether by acceleration or otherwise, and at all times thereafter, of all obligations of the Debtor to the Banks or the Agent under the Second Amended and Restated Credit Agreement, each Note issued thereunder, and each other Loan Document (as defined therein), including without limitation all future advances, and all obligations to reimburse the Agent for drawings under all Letters of Credit, and all of such obligations that arise after the filing of a petition by or against the Debtor under the Bankruptcy Code, even if the obligations do not accrue because of the automatic stay under Bankruptcy Code Section 362 or otherwise (all such obligations being hereinafter collectively called the “Liabilities”), and the Guarantors further jointly and severally agree to pay all expenses (including attorneys’ fees and legal expenses) paid or incurred by the Banks or Agent in endeavoring to collect the Liabilities, or any part thereof, and in enforcing this guaranty.

The Guarantors agree that, in the event of the dissolution or insolvency of the Debtor or any Guarantor, or the inability of the Debtor or any Guarantor to pay debts as they mature, or an assignment by the Debtor or any Guarantor for the benefit of creditors, or the institution of any proceeding by or against the Debtor or the Guarantor alleging that the Debtor or any Guarantor is insolvent or unable to pay debts as they mature, and if such event shall occur at a time when any of the Liabilities may not then be due and payable, the Guarantors will pay to the Agent forthwith the full amount which would be payable hereunder by the Guarantors if all Liabilities were then due and payable.

In addition to, and without limitation of, any rights of the Agent and the Banks under applicable law, if any Event of Default occurs and is continuing under the Second Amended and Restated Credit Agreement, upon written direction by the Agent to such effect any and all deposits (including all account balances, whether provisional or final and whether or not collected or available) and any other Indebtedness (as defined in the Second Amended and Restated Credit Agreement) at any time held or owing by the Agent or any Bank to or for the credit or account of any Guarantor may be offset and applied toward the payment of the Liabilities and all obligations of the Guarantors hereunder, whether or not the Liabilities and all obligations of the Guarantors hereunder, or any part thereof, shall then be due.

This guaranty shall in all respects be a continuing, absolute and unconditional guaranty, and shall remain in full force and effect (notwithstanding, without limitation, the dissolution of

any Guarantor or that at any time or from time to time all Liabilities may have been paid in full). This guaranty is a guaranty of payment and performance and not merely a guaranty of collection.

The Guarantors further agree that, if at any time all or any part of any payment theretofore applied by the Agent or the Banks to any of the Liabilities is or must be rescinded or returned by the Agent or the Banks for any reason whatsoever (including, without limitation, the insolvency, bankruptcy or reorganization of the Debtor), such Liabilities shall, for the purposes of this guaranty, to the extent that such payment is or must be rescinded or returned, be deemed to have continued in existence, notwithstanding such application by the Agent or the Banks, and this guaranty shall continue to be effective or be reinstated, as the case may be, as to such Liabilities, all as though such application by the Agent or the Banks had not been made.

The Agent and the Banks may, from time to time, at their sole discretion and without notice to any Guarantor, take any or all of the following actions: (a) be granted a security interest in any property to secure any of the Liabilities or the Guaranty Obligations, (b) retain or obtain the primary or secondary obligation of any obligor or obligors, in addition to the Guarantors, with respect to any of the Liabilities, (c) extend or renew for one or more periods (whether or not longer than the original period), alter or exchange any of the Liabilities, or release or compromise any obligation of any nature of any other obligor with respect to any of the Liabilities, (d) release its security interest in, or surrender, release or permit any substitution or exchange for, all or any part of any property securing any of the Liabilities or any obligation hereunder, or extend or renew for one or more periods (whether or not longer than the original period) or release, compromise, alter or exchange any obligations of any nature of any obligor with respect to any such property, and (e) resort to any Guarantor for payment of any of the Liabilities, whether or not the Agent and the Banks (i) shall have resorted to any property securing any of the Liabilities or (ii) shall have proceeded against any other obligor primarily or secondarily obligated with respect to any of the Liabilities including without limitation any other Guarantor (all of the actions referred to in preceding clauses (i) and (ii) being hereby expressly waived by each Guarantor).

Any amounts received by the Agent and the Banks from whatsoever source on account of the Liabilities may be applied by it toward the payment of such of the Liabilities, and in such order of application, as the Agent may from time to time elect.

Until such time as this guaranty shall have been discontinued and the Agent and the Banks shall have received payment of the full amount of all Liabilities and of all obligations of the Guarantors hereunder, no payment made by or for the account of the Guarantors pursuant to this guaranty shall entitle the Guarantors by subrogation or otherwise to any payment by the Debtor or from or out of any property of the Debtor and the Guarantors shall not exercise any right or remedy against the Debtor or any property of the Debtor by reason of any performance by the Guarantors of this guaranty.

The Guarantors hereby expressly waive: (a) notice of the acceptance by the Agent or the Banks of this guaranty, (b) notice of the existence or creation or non-payment of all or any of the Liabilities, (c) presentment, demand, notice of dishonor, protest, and all other notices whatsoever, and (d) all diligence in collection or protection of or realization upon the Liabilities

or any part thereof, any obligation hereunder, or any security for, or guaranty of, any of the foregoing.

Each Bank may from time to time without notice to the Guarantors, assign or transfer its Percentage (as defined in the Second Amended and Restated Credit Agreement) or any or all of the Liabilities or any interest therein; and, notwithstanding any such assignment or transfer or any subsequent assignment or transfer thereof, such Liabilities shall be and remain Liabilities for the purposes of this guaranty, and each and every immediate and successive assignee or transferee of any of the Liabilities or of any interest therein shall, to the extent of the interest of such assignee or transferee in the Liabilities, be entitled to the benefits of this guaranty to the same extent as if such assignee or transferee were such Bank.

Unless the Agent shall otherwise consent in writing, the Agent shall have the sole right to enforce this Guaranty, as Agent as provided in the Second Amended and Restated Credit Agreement, for the benefit of the Agent and the Banks (including any transferee, as provided in the prior paragraph).

Each Guarantor hereby warrants to the Agent and the Banks that such Guarantor now has, and will continue to have independent means of obtaining information concerning the affairs, financial condition and business of the Debtor. Neither the Agent nor the Bank shall have any duty or responsibility to provide the Guarantors with any credit or other information concerning the affairs, financial condition or business of the Debtor which may come into the Agent’s or the Bank’s possession.

No delay on the part of the Agent or any Bank in the exercise of any right or remedy shall operate as a waiver thereof, and no single or partial exercise by the Agent or any Bank of any right or remedy shall preclude other or further exercise thereof or the exercise of any other right or remedy; nor shall any modification or waiver of any of the provisions of this guaranty be binding upon the Agent or any Bank except as expressly set forth in a writing duly signed and delivered on behalf of the Agent and the Required Banks (as defined in the Second Amended and Restated Credit Agreement). No action of the Agent or the Banks permitted hereunder shall in any way affect or impair the rights of the Agent or the Banks and the obligations of the Guarantors under this guaranty. For the purposes of this guaranty, Liabilities shall include all obligations of the Debtor to the Agent or the Banks specified as Liabilities, notwithstanding any right or power of the Debtor or anyone else to assert any claim or defense as to the invalidity or unenforceability of any such obligation, and no such claim or defense shall affect or impair the obligations of the Guarantors hereunder, and shall specifically include, without limitation, any and all interest, fees or commissions included in the Liabilities and accruing or payable after the commencement of any bankruptcy or insolvency proceedings, notwithstanding any provision or rule of law which might restrict the rights of the Bank to collect such obligations from the Debtor. The obligations of the Guarantors under this guaranty shall be absolute and unconditional irrespective of any circumstance whatsoever which might constitute a legal or equitable discharge or defense of any Guarantor. The Guarantors hereby acknowledge that there are no conditions to the effectiveness of this guaranty.

This guaranty shall be binding upon each Guarantor, and upon the successors and assigns of each Guarantor.

Agreement described herein

U.S. Bank National Association
Bank of America, N.A.
JPMorgan Chase Bank, N.A.
KeyBank National Association
Xxxxx Fargo Bank, National Association
Bank of the West
Union Bank of California, N.A.

Ladies and Gentlemen:

I have acted as counsel to Otter Tail Corporation, a Minnesota corporation (the “Company”), in connection with entry by the Company into that certain Second Amended and Restated Credit Agreement, dated as of May 4, 2010, among the Company, the Banks, as defined therein, and U.S. Bank National Association, as Agent (the “Second Amended and Restated Credit Agreement”), and to the Material Subsidiaries, as defined in the Second Amended and Restated Credit Agreement (the “Material Subsidiaries”), in connection with entry by the Material Subsidiaries into that certain Material Subsidiary Guaranty, dated as of May 4, 2010 (the “Material Subsidiary Guaranty”). This opinion is being delivered to you pursuant to Section 6.1 of the Second Amended and Restated Credit Agreement. Capitalized terms used herein, except as otherwise specifically defined herein, are used with the same meaning as defined in the Second Amended and Restated Credit Agreement.

In connection with this opinion, I have examined the following documents:

(a) The Articles or Certificate of Incorporation of the Company and each Material Subsidiary;

(b) The Bylaws of the Company and each Material Subsidiary;

(d) An executed copy of the Second Amended and Restated Credit Agreement and the Material Subsidiary Guaranty.

I also have examined such other documents and reviewed such questions of law as I have considered necessary and appropriate for the purposes of this opinion.

In rendering my opinions set forth below, I have assumed the authenticity of all documents submitted to me as originals, the genuineness of all signatures (other than the signatures of officers of the Company and each Material Subsidiary) and the conformity to authentic originals of all documents submitted to me as copies. I also have assumed the legal capacity for all purposes relevant hereto of all natural persons (other than officers of the Company and each Material Subsidiary) and, with respect to all parties to agreements or instruments relevant hereto other than the Company and each Material Subsidiary, that such parties had the requisite power and authority (corporate or otherwise) to execute, deliver and perform such agreements or instruments, that such agreements or instruments have been duly authorized by all requisite action (corporate or otherwise), executed and delivered by such parties and that such agreements or instruments are the valid, binding and enforceable obligations of such parties. As to questions of fact material to my opinion, I have relied upon representations and certificates of officers and other employees of the Company and each Material Subsidiary (known by me to have authority to make such representations and certifications on behalf of the Company and each Material Subsidiary) and certificates of public officials.

Based on the foregoing, I am of the opinion that:

(i) The Company is and each Material Subsidiary is a corporation duly organized, validly existing and in good standing under the laws of the state of its incorporation, and each is duly qualified and in good standing as a foreign corporation in all other jurisdictions in which its respective present operations or properties require such qualification, except where failure so to qualify or to be in good standing would not constitute an Adverse Event.

(ii) The Company and each Material Subsidiary each has full corporate power and authority to (a) own and operate its properties and assets and carry on its business as presently conducted, as described with respect to the Company in Otter Tail Corporation’s Annual Report or Form 10-K for the year ended December 31, 20[_], and (b) enter into and perform its obligations under the Loan Documents to which it is a party.

(iii) The execution and delivery by each of the Company and each Material Subsidiary of the Loan Documents to which it is a party, the borrowing by the Company under the Second Amended and Restated Credit Agreement, and the performance by each of the Company and each Material Subsidiary of its respective obligations under the Loan Documents to which it is a party have been duly authorized by all necessary corporate action, and the Loan Documents have been duly executed and delivered on behalf of the Company and each Material Subsidiary, as applicable and constitute valid and binding obligations of the Company and each Material Subsidiary, as applicable, enforceable in accordance with their respective terms.

(iv) There is no provision in (a) the Company’s or any Material Subsidiary’s Articles or Certificate of Incorporation or Bylaws, (b) any indenture, mortgage, contract or agreement to which the Company or any Material Subsidiary is a party or by which the Company or any Material Subsidiary or its respective properties are bound, (c) any law, statute, rule or regulation or (d) any writ, order or decision of any court or governmental instrumentality binding on the Company or any Material Subsidiary which would be contravened by the execution, delivery or performance by the Company or any Material Subsidiary of the Loan Documents to

which it is a party, except in the case of clauses (b) and (d) for any such contravention which would not constitute an Adverse Event.

(v) There are no actions, suits or proceedings pending or, to the best of my knowledge, threatened against the Company or any Material Subsidiary before any court or arbitrator or by or before any administrative agency or government authority, which, if adversely determined, could reasonably be expected to constitute an Adverse Event.

The opinion set forth in paragraph (iii) above is subject to the following qualifications and exceptions:

	(i)		The opinion set forth in paragraph (iii) above is subject to the effect of any applicable bankruptcy, insolvency, reorganization, arrangement, moratorium, fraudulent transfer, statutes of limitation or other similar laws and judicial decisions affecting or relating to the rights of creditors generally.

	(ii)		The opinion set forth in paragraph (iii) above is subject to the effect of general principles of equity, including without limitation, concepts of materiality, reasonableness, good faith and fair dealing, estoppel, election of remedies and other similar doctrines affecting the enforceability of agreements generally (regardless of whether considered in a proceeding in equity or at law). In addition, the availability of specific performance, injunctive relief, the appointment of a receiver or other equitable remedies is subject to the discretion of the tribunal before which any proceeding therefor may be brought.

	(iii)		I express no opinion as to the enforceability of provisions in the Loan Documents to the extent they contain obligations of the Company or any Material Subsidiary to pay any prepayment premium, default interest rate or other form of liquidated damages if the payment of such premium, interest rate or damages may be construed as unreasonable in relation to the actual damages or disproportionate to actual damages suffered by the party claiming such amounts as a result of such prepayment or default.

	(iv)		I express no opinion (A) as to the validity, binding effect or enforceability of (1) any provision of the Loan Documents related to choice of law, forum selection or submission to jurisdiction (including, without limitation, any express or implied waiver of any objection to venue in any court or of any objection that a court is an inconvenient forum), (2) waivers by the Company or any Material Subsidiary of any statutory or constitutional rights or remedies, (3) terms which excuse any person or entity from liability for such person’s or entity’s negligence or willful misconduct, or (4) cumulative remedies to the extent such cumulative remedies purport to compensate, or would have the effect of compensating, the party entitled to the benefits thereof in an amount in excess of the actual loss suffered by such party; or (B) as to compliance or the effect of noncompliance by you with any state or federal laws or regulations applicable to you in connection with the transactions described in the Loan Documents.

(v)

The opinion set forth in paragraph (iii) above with respect to the Material Subsidiary Guaranty is subject to the defenses available to a guarantor under applicable law, but the waivers of such defenses set forth in the Material Subsidiary Guaranty are enforceable, subject to the other exceptions set forth herein.

I draw your attention to the fact that, under certain circumstances, the enforceability of terms to the effect that provisions may not be waived or modified except in writing may be limited.

The opinions expressed above are limited to the laws of the States of Minnesota and North Dakota and the federal laws of the United States and, with respect to my opinion in paragraphs (i), (ii) and (iv) only, the following corporate laws: the Arizona Business Corporation Act, the Delaware General Corporation Law, the Idaho Business Corporation Act, and the General and Business Corporation Law of Missouri. I express no opinion as to the laws of any other jurisdiction.

The foregoing opinions are being furnished to you solely for your benefit and may not be relied upon by, nor may copies be delivered to, any other person without my prior written consent.


	Very truly yours,

	Xxxxxx X. Xxxxx
