Each request for Loans hereunder shall specify (i) the requested Loan Date, (ii) the aggregate amount of Loans to be made on such date which shall be in a minimum amount of $100,000 or, if more, an integral multiple thereof, provided, however, that Swing Line Loans may be in any amount requested by the Borrower, (iii) whether Revolving Loans are to be funded as Prime Rate Advances or LIBOR Advances (and, if such Revolving Loans are to be made with more than one applicable interest rate choice, specifying the amount to which each interest rate choice is applicable) and (iv) in the case of LIBOR Advances, the duration of the initial Interest Period applicable thereto. The Agent may rely on any telephone request for Loans hereunder which it believes in good faith to be genuine; and the Borrower hereby waives the right to dispute the Agent’s record of the terms of such telephone request absent manifest error.

2.2(d) The Agent shall promptly notify each other Bank of the receipt of such request, the matters specified therein, and of such Bank’s ratable share 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 2:00 p.m., Minneapolis time. Unless the Agent determines that any applicable condition specified in Article 3 has not been satisfied, the Agent will make available to the Borrower at the Agent’s principal office in Minneapolis, Minnesota in Immediately Available Funds not later than 2:00 p.m. (Minneapolis time) on the requested Loan Date the amount of the requested Revolving Loans. If the Agent does not receive funding from any Bank of its Revolving Percentage of any Revolving Loan 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 (or rates) then applicable to such Revolving Loan (but not including any funding losses with respect to such Revolving Loan that is a LIBOR Advance), on demand, from the Borrower, without prejudice to the Agent’s and the Borrower’s rights against such non-funding Bank. Such Bank’s obligations in respect of such funding are set forth in Section 2.30 hereof.

Section 2.3 Notes.

2.3(a) The Revolving Loans of each Bank shall be evidenced by a single Revolving Note payable to the order of such Bank in a principal amount equal to such Bank’s Revolving Commitment Amount originally in effect.

2.3(b) The Swing Line Loans of the Swing Line Bank shall be evidenced by a single Swing Line Note payable to the order of the Swing Line Bank in a principal amount equal to the Swing Line Commitment Amount originally in effect.

2.3(c) Each Bank shall enter in its ledgers and records the amount of each Loan, the various Advances made, converted or continued and the payments made thereon, and each Bank is authorized by the Borrower to enter on a schedule attached to its Note or Notes a record of such Loans, Advances and payments; provided, however that the failure by any Bank to make any such entry or any error in making such entry shall not limit or otherwise affect the obligation of the Borrower hereunder and on the Notes, and, in all events, the principal amounts owing by the Borrower in respect of the Notes shall be the aggregate amount of all Loans made by the Banks less all payments of principal thereof made by the Borrower.

Section 2.4 Conversions and Continuations. On the terms and subject to the limitations hereof, the Borrower shall have the option at any time and from time to time to convert all or any portion of the Revolving Loans into Prime Rate Advances or LIBOR Advances, or to continue a LIBOR Advance as such; provided, however that a LIBOR Advance may be converted or continued only on the last day of the Interest Period applicable thereto and no Advance may be converted to or continued as a LIBOR Advance if a Default or Event of Default has occurred and is continuing on the proposed date of continuation or conversion. Advances may be converted to, or continued as, LIBOR Advances only in integral multiples, as to the aggregate amount of the Advances of all Banks so converted or continued, of $100,000 or, if larger, in integral multiples of $100,000. The Borrower shall give the Agent written notice of any continuation or conversion of any Advances and such notice must be given so as to be received by the Agent not later than 12:00 noon (Minneapolis time) two Business Days prior to the requested date of conversion to, or continuation of, LIBOR Advances and on the date of the requested conversion to Prime Rate Advances. Each such notice shall specify (a) the amount to be continued or converted, (b) the date for the continuation or conversion (which must be (i) the last day of the preceding Interest Period for any continuation or conversion of LIBOR Advances, and (ii) a Business Day in the case of continuations as or conversions to LIBOR Advances and a Business Day in the case of conversions to Prime Rate Advances), and (c) in the case of conversions to or continuations as LIBOR Advances, the Interest Period applicable thereto. Any notice given by the Borrower under this Section shall be irrevocable. If the Borrower shall fail to

notify the Agent of the continuation of any LIBOR Advances within the time required by this Section, such Advances shall, on the last day of the Interest Period applicable thereto automatically be continued as LIBOR Advance of the same type and the same Interest Period if LIBOR Advances shall be available to the Borrower, otherwise such Advances shall be converted to Prime Rate Advances. All conversions and continuation of Advances must be made uniformly and ratably among the Banks (e.g., when continuing a two-month LIBOR Advance of one Bank to a three-month LIBOR Advance, the Borrower must simultaneously continue all two-month LIBOR Advances of all Banks having Interest Periods ending on the date of continuation as three-month LIBOR Advances.)

Section 2.5 Refunding of Swing Line Loans.

2.5(a) Swing Line Loans are only intended to be outstanding for a period of five (5) Business Days or less after the making thereof. To maintain compliance with this limitation, 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 then outstanding. If the Borrower shall not make such requests in a timely manner, or 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 direct 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 Prime Rate Advance), in an amount equal to such Bank’s Revolving 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 shall immediately be applied by the Swing Line Bank to repay the Refunded Swing Line Loans.

2.5(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 2.5(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 2.5(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.

2.5(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.

2.5(d) Each Bank’s obligation to make the Loans referred to in Section 2.5(a) and to purchase participating interests pursuant to Section 2.5(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 or continuance of a Default or an Event of Default or the failure to satisfy any of the other conditions precedent specified in Article 3; (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 2.6 Interest Rates, Interest Payments and Default Interest. Interest shall accrue and be payable on the Revolving Loans as follows:

2.6(a) Subject to paragraph (d) below, each LIBOR Advance shall bear interest on the unpaid principal amount thereof during the Interest Period applicable thereto at a rate per annum equal to the sum of (i) LIBOR (Reserve Adjusted) for such Interest Period, plus (ii) the Applicable Margin.

2.6(b) Subject to paragraph (d) below, each Prime Rate Advance shall bear interest on the unpaid principal amount thereof at a varying rate per annum equal to the sum of (i) the Prime Rate, plus or minus, as applicable, (ii) the Applicable Margin.

2.6(c) Subject to paragraph (d) below, each Daily Floating LIBOR Advance shall bear interest on the unpaid principal amount thereof at a varying rate per annum equal to the sum of (i) the Daily Floating LIBOR Rate, plus (ii) the Applicable Margin.

2.6(d) Upon the occurrence of any Event of Default, each Advance shall, at the option of the Required Banks, bear interest until paid in full (i) during the balance of any Interest Period applicable to such Advance, at a rate per annum equal to the sum of the rate applicable to such Advance during such Interest Period plus 2.00%, or (ii) otherwise, at a rate per annum equal to the Prime Rate plus 2.00%.

2.6(e) Interest shall be payable (i) with respect to each LIBOR Advance having an Interest Period of three months or less, on the last day of the Interest Period applicable thereto; (ii) with respect to any LIBOR Advance having an Interest Period greater than three months, on the last day of the Interest Period applicable thereto and on each day that would have been the last day of the Interest Period for such Advance had successive Interest Periods of three months duration been applicable to such Advance; (iii) with

respect to any Prime Rate Advance, on the last day of each month; (iv) with respect to all Advances, upon any permitted prepayment (on the amount prepaid); and (E) with respect to all Advances, on the Termination Date; provided that interest under Section 2.6(d) shall be payable on demand.

Section 2.7 Repayment. The unpaid principal amount of all Advances, together with all accrued and unpaid interest thereon, shall be due and payable on the Termination Date.

Section 2.8 Prepayments.

2.8(a) Mandatory Payments. If at any time a Borrowing Base Deficiency exists, the Borrower shall immediately pay on the principal of the Advances an amount equal to such Borrowing Base Deficiency. Any such payments shall be applied first against Prime Rate Advances and then to LIBOR Advances in order starting with the LIBOR Advances having the shortest time to the end of the applicable Interest Period. Amounts paid on the Advances under this paragraph (a) shall be for the account of each Bank in proportion to its share of outstanding Revolving Loans. If, after paying all outstanding Advances, a Borrowing Base Deficiency still exists, the Borrower shall pay into the Holding Account an amount equal to the amount of the remaining Borrowing Base Deficiency.

2.8(b) Other Mandatory Prepayments. If at any time Total Outstandings exceed the Aggregate Revolving Commitment Amounts, the Borrower shall immediately repay to the Agent for the account of the Banks the amount of such excess. Any such payments shall be applied first against Prime Rate Advances and then to LIBOR Advances in order starting with the LIBOR Advances having the shortest time to the end of the applicable Interest Period. If, after payment of all outstanding Advances, the Total Outstandings still exceed the Aggregate Revolving Commitment Amounts, the remaining amount paid by the Borrower shall be placed in the Holding Account.

2.8(c) Optional Prepayments. The Borrower may prepay Prime Rate Advances, in whole or in part, at any time, without premium or penalty. Any such prepayment must be accompanied by accrued and unpaid interest on the amount prepaid. Each partial prepayment shall be in an aggregate amount for all the Banks of $100,000 or an integral multiple thereof. Except upon an acceleration following an Event of Default or upon termination of the Revolving Commitments in whole or as required under Sections 2.8(a) or (b), the Borrower may pay LIBOR Advances only on the last day of the Interest Period applicable thereto. Amounts paid (unless following an acceleration or upon termination of the Revolving Commitments in whole) or prepaid on Advances under this paragraph (c) may be reborrowed upon the terms and subject to the conditions and limitations of this Agreement. Amounts paid or prepaid on the Advances under this paragraph (c) shall be for the account of each Bank in proportion to its share of outstanding Revolving Loans.

Part B — Terms of the Letter of Credit Facility

Section 2.9 Letters of Credit. Upon the terms and subject to the conditions of this Agreement, the Agent agrees to issue Letters of Credit for the account of the Borrower from time

to time between the Closing Date and the Termination Date in such amounts as the Borrower shall request up to an aggregate amount at any time outstanding not exceeding the Letter of Credit Sublimit; provided that no Letter of Credit will be issued in any amount which, after giving effect to such issuance, would cause Total Outstandings to exceed the lesser of (a) the Aggregate Revolving Commitment Amounts, or (b) the Borrowing Base.

Section 2.10 Procedures for Letters of Credit. Each request for a Letter of Credit shall be made by the Borrower in writing, by telex, facsimile transmission or electronic conveyance received by the Agent by 2:00 p.m., Minneapolis time, on a Business Day which is not less than one Business Day preceding the requested date of issuance (which shall also be a Business Day). Each request for a Letter of Credit shall be deemed a representation by the Borrower that on the date of issuance of such Letter of Credit and after giving effect thereto the applicable conditions specified in Article 3 have been and will be satisfied. The Agent may require that such request be made on such letter of credit application and reimbursement agreement form as the Agent may from time to time specify, along with satisfactory evidence of the authority and incumbency of the officials of the Borrower making such request. The Agent shall promptly notify the other Banks of the receipt of the request and the matters specified therein. On the date of each issuance of a Letter of Credit the Agent shall send notice to the other Banks of such issuance, accompanied by a copy of the Letter or Letters of Credit so issued.

Section 2.11 Terms of Letters of Credit. Letters of Credit shall be issued in support of obligations of the Borrower. All Letters of Credit must expire not later than the Business Day preceding the Termination Date. No Letter of Credit may have a term longer than twelve months (except for standard “evergreen” Letters of Credit containing automatic extension provisions in form acceptable to the Agent).

Section 2.12 Agreement to Repay Letter of Credit Drawings. If the Agent has received documents purporting to draw under a Letter of Credit that the Agent believes conform to the requirements of the Letter of Credit, it shall honor such drawing and provide Borrower with a notice of such drawing. If the Agent has received documents purporting to draw under a Letter of Credit that the Agent believes does not conform to the requirements of the Letter of Credit, it shall notify the Borrower of such fact and, if Agent nevertheless is authorized to honor such draw by the Borrower, the Agent may honor such nonconforming draw, provided, however, if a Default has occurred and is continuing, the Agent may do so only with the consent of all of the Banks. The Borrower shall reimburse the Agent by 9:30 a.m. (Minneapolis time) on the day on which such drawing is to be paid in Immediately Available Funds in an amount equal to the amount of such drawing. Any amount by which the Borrower has failed to reimburse the Agent for the full amount of such drawing by 10:00 a.m. on the date on which the Agent in its notice indicated that it would pay such drawing, until reimbursed from the proceeds of Loans pursuant to Section 2.14 or out of funds available in the Holding Account, is an “Unpaid Drawing.”

Section 2.13 Obligations Absolute. The obligation of the Borrower under Section 2.12 to repay the Agent for any amount drawn on any Letter of Credit and to repay the Banks for any Revolving Loans made under Section 2.16 to cover Unpaid Drawings shall be absolute, unconditional and irrevocable, shall continue for so long as any Letter of Credit is outstanding notwithstanding any termination of this Agreement, and shall be paid strictly in accordance with

the terms of this Agreement, under all circumstances whatsoever, including without limitation the following circumstances:

2.13(a) Any lack of validity or enforceability of any Letter of Credit;

2.13(b) The existence of any claim, setoff, defense or other right which the Borrower may have or claim at any time against any beneficiary, transferee or holder of any Letter of Credit (or any Person for whom any such beneficiary, transferee or holder may be acting), the Agent or any Bank or any other Person, whether in connection with a Letter of Credit, this Agreement, the transactions contemplated hereby, or any unrelated transaction; or

2.13(c) Any statement or any other document presented under any Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect whatsoever.

Neither the Agent nor any Bank nor officers, directors or employees of any thereof shall be liable or responsible for, and the obligations of the Borrower to the Agent and the Banks shall not be impaired by:

(i) The use which may be made of any Letter of Credit or for any acts or omissions of any beneficiary, transferee or holder thereof in connection therewith;

(ii) The validity, sufficiency or genuineness of documents, or of any endorsements thereon, even if such documents or endorsements should, in fact, prove to be in any or all respects invalid, insufficient, fraudulent or forged;

(iii) The acceptance by the Agent of documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary; or

(iv) Any other action of the Agent in making or failing to make payment under any Letter of Credit if in good faith and in conformity with U.S. or foreign laws, regulations or customs applicable thereto.

Notwithstanding the foregoing, the Borrower shall have a claim against the Agent, and the Agent shall be liable to the Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential, damages suffered by the Borrower which the Borrower proves were caused by the Agent’s willful misconduct or gross negligence in determining whether documents presented under any Letter of Credit comply with the terms thereof.

Section 2.14 Existing Letters of Credit. The Existing Letters of Credit shall be deemed for all purposes to have been issued under this Agreement and shall constitute “Letters of Credit” under this Agreement.

Part C — General

Section 2.15 Optional Reduction of Revolving Commitment Amounts or Termination of Revolving Commitments. The Borrower may, at any time, upon not less than two Business Days prior written notice to the Agent, reduce the Revolving Commitment Amounts, ratably, with any such reduction in a minimum aggregate amount for all the Banks of $1,000,000, or, if more, in an integral multiple of $1,000,000; provided, however, that the Borrower may not at any time reduce the Aggregate Revolving Commitment Amounts below the Total Outstandings. The Borrower may, at any time when there are no Letters of Credit outstanding, upon not less than two Business Days prior written notice to the Agent, terminate the Revolving Commitments in their entirety. Upon termination of the Revolving Commitments pursuant to this Section, the Borrower shall pay to the Agent for the account of the Banks the full amount of all outstanding Advances, all accrued and unpaid interest thereon, all unpaid Revolving Commitment Fees accrued to the date of such termination, any indemnities payable with respect to Advances pursuant to Section 2.27 and all other unpaid obligations of the Borrower to the Agent and the Banks hereunder.

Section 2.16 Loans to Cover Unpaid Drawings. Whenever any Unpaid Drawing exists for which there are not then funds in the Holding Account to cover the same, the Agent shall give the other Banks notice to that effect, specifying the amount thereof, in which event each Bank is authorized (and the Borrower does here so authorize each Bank) to, and shall, make a Revolving Loan (as a Prime Rate Advance) to the Borrower in an amount equal to such Bank’s Revolving Percentage of the amount of the Unpaid Drawing. The Agent shall notify each Bank by 11:00 a.m. (Minneapolis time) on the date such Unpaid Drawing occurs of the amount of the Revolving Loan to be made by such Bank. Notices received after such time shall be deemed to have been received on the next Business Day. Each Bank shall then make such Revolving Loan (regardless of noncompliance with the applicable conditions precedent specified in Article 3 hereof and regardless of whether an Event of Default then exists) and each Bank shall provide the Agent with the proceeds of such Revolving Loan in Immediately Available Funds, at the office of the Agent, not later than 2:00 p.m. (Minneapolis time) on the day on which such Bank received such notice (or, in the case of notices received after 11:00 a.m., Minneapolis time, is deemed to have received such notice). The Agent shall apply the proceeds of such Revolving Loans directly to reimburse itself for such Unpaid Drawing. If any portion of any such amount paid to the Agent should be recovered by or on behalf of the Borrower from the Agent in bankruptcy, by assignment for the benefit of creditors or otherwise, the loss of the amount so recovered shall be ratably shared between and among the Banks in the manner contemplated by Section 8.10 hereof. If at the time the Banks make funds available to the Agent pursuant to the provisions of this Section, the applicable conditions precedent specified in Article 3 shall not have been satisfied, the Borrower shall pay to the Agent for the account of the Banks interest on the funds so advanced at a floating rate per annum equal to the sum of the Prime Rate plus two percent (2.00%). If for any reason any Bank is unable to make a Revolving Loan to the Borrower to reimburse the Agent for an Unpaid Drawing, then such Bank shall immediately purchase from the Agent a risk participation in such Unpaid Drawing, at par, in an amount equal to such Bank’s Revolving Percentage of the Unpaid Drawing.

Section 2.17 Revolving Commitment Fee. The Borrower shall pay to the Agent for the account of each Bank fees (the “Revolving Commitment Fees”) in an amount determined by

applying the Applicable Commitment Fee Percentage to the average daily Unused Revolving Commitment of such Bank for the period from the Closing Date to the Termination Date. Such Revolving Commitment Fees are payable in arrears quarterly on the last day of each fiscal quarter and on the Termination Date.

Section 2.18 Letter of Credit Fees, Letter of Credit Default Fees and Administrative Fees. For each Letter of Credit issued, the Borrower shall pay to the Agent for the account of the Banks, in advance payable on the date of issuance, a fee (a “Letter of Credit Fee”) in an amount determined by applying the Applicable Margin for LIBOR Advances to the original face amount of the Letter of Credit for the period from the date of issuance to the scheduled expiration date of such Letter of Credit. In addition, upon occurrence of any Event of Default, the Borrower shall pay to the Agent for the account of the Banks a fee in an amount determined by applying the rate of 2.00% per annum (the “Letter of Credit Default Fee”) to the face amount of the Letter of Credit for the period from the date of such Event of Default to the scheduled expiration date of such Letter of Credit. In addition to the Letter of Credit Fee, the Borrower shall pay to the Agent, on demand, all issuance, amendment, drawing and other fees regularly charged by the Agent to its letter of credit customers and all out-of-pocket expenses incurred by the Agent in connection with the issuance, amendment, administration or payment of any Letter of Credit, and a fronting fee for each Letter of Credit issued equal to 0.125% of the stated amount of the Letter of Credit as of the date of issuance.

Section 2.19 Agent’s Fee. The Borrower shall pay fees to the Agent for its own account in amounts and at times provided in the Agent’s Fee Letter.

Section 2.20 Computation. Revolving Commitment Fees, Letter of Credit Fees, Letter of Credit Default Fees and interest on Advances shall be computed on the basis of actual days elapsed (or, in the case of Letter of Credit Fees which are paid in advance, actual days to elapse) and a year of 360 days, provided, that interest that is determined with reference to the Prime Rate shall be computed on the basis of actual days elapsed and a year of 365 or 366 days.

Section 2.21 Payments. Payments and prepayments of principal of, and interest on, the Notes and all fees, expenses and other obligations under this Agreement payable to the Agent or the Banks shall be made without setoff or counterclaim in Immediately Available Funds not later than 1:00 p.m. (Minneapolis time) on the dates called for under this Agreement and the Notes to the Agent at its main office in Minneapolis, Minnesota. Funds received after such time shall be deemed to have been received on the next Business Day. The Agent will promptly distribute in like funds to each Bank its ratable share of each such payment of principal, interest, Revolving Commitment Fees and Letter of Credit Fees received, by the Agent for the account of the Banks. 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, in the case of a payment of principal, shall be included in the computation of any interest on such principal payment.

Section 2.22 Use of Loan Proceeds. The proceeds of the Loans shall be used for the Borrower’s general business and working capital purposes in a manner not in conflict with any of the Borrower’s covenants in this Agreement.

Section 2.23 Interest Rate Not Ascertainable, Etc. If, on or prior to the date for determining LIBOR (Reserve Adjusted) in respect of the Interest Period for any LIBOR Advance, any Bank determines (which determination shall be conclusive and binding, absent error) that:

2.23(a) deposits in dollars (in the applicable amount) are not being made available to such Bank in the relevant market for such Interest Period, or

2.23(b) LIBOR (Reserve Adjusted) will not adequately and fairly reflect the cost to such Bank of funding or maintaining LIBOR Advances for such Interest Period,

such Bank shall forthwith give notice to the Borrower and the other Banks of such determination, whereupon the obligation of such Bank to make or continue, or to convert any Advances to, LIBOR Advances shall be suspended until such Bank notifies the Borrower and the Agent that the circumstances giving rise to such suspension no longer exist. While any such suspension continues, all further Advances by such Bank shall be made as Prime Rate Advances. No such suspension shall affect the interest rate then in effect during the applicable Interest Period for any LIBOR Advance outstanding at the time such suspension is imposed.

Section 2.24 Increased Cost. If any Regulatory Change:

2.24(a) shall subject any Bank (or its Applicable Lending Office) to any tax, duty or other charge with respect to its LIBOR Advances, its Note or its obligation to make LIBOR Advances or shall change the basis of taxation of payment to any Bank (or its Applicable Lending Office) of the principal of or interest on its LIBOR Advances or any other amounts due under this Agreement in respect of its LIBOR Advances or its obligation to make LIBOR Advances (except for changes in the rate of tax on the overall net income of such Bank or its Applicable Lending Office imposed by the jurisdiction in which such Bank’s principal office or Applicable Lending Office is located); or

2.24(b) shall impose, modify or deem applicable any reserve, special deposit or similar requirement (including, without limitation, any such requirement imposed by the Board, but excluding with respect to any LIBOR Advance any such requirement to the extent included in calculating the applicable LIBOR (Reserve Adjusted)) against assets of, deposits with or for the account of, or credit extended by, any Bank’s Applicable Lending Office or against Letters of Credit issued by the Agent or shall impose on any Bank (or its Applicable Lending Office) or the interbank eurodollar market any other condition affecting its LIBOR Advances, its Note or its obligation to make LIBOR Advances or affecting any Letter of Credit;

and the result of any of the foregoing is to increase the cost to such Bank (or its Applicable Lending Office) of making or maintaining any LIBOR Advance or issuing or maintaining any Letter of Credit, or to reduce the amount of any sum received or receivable by such Bank (or its Applicable Lending Office) under this Agreement or under its Note, then, within 30 days after demand by such Bank (with a copy to the Agent), the Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank for such increased cost or reduction. Each Bank will promptly notify the Borrower and the Agent of any event of which it

has knowledge, occurring after the date hereof, which will entitle such Bank to compensation pursuant to this Section and will designate a different Applicable Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Bank, be otherwise disadvantageous to such Bank. If any Bank fails to give such notice within 45 days after it obtains knowledge of such an event, such Bank shall, with respect to compensation payable pursuant to this Section, only be entitled to payment under this Section for costs incurred from and after the date 45 days prior to the date that such Bank does give such notice. A certificate of any Bank claiming compensation under this Section, setting forth the additional amount or amounts to be paid to it hereunder and stating in reasonable detail the basis for the charge and the method of computation, shall be conclusive in the absence of error. In determining such amount, any Bank may use any reasonable averaging and attribution methods. Failure on the part of any Bank to demand compensation for any increased costs or reduction in amounts received or receivable with respect to any Interest Period shall not constitute a waiver of such Bank’s rights to demand compensation for any increased costs or reduction in amounts received or receivable in any subsequent Interest Period. Each of the Banks agrees that, as promptly as practicable after becoming aware of the occurrence of an event or the existence of a condition that would entitle such Bank to receive payments under this Section 2.24, it will, to the extent not inconsistent with the internal policies of such Bank and any applicable legal or regulatory restrictions, take reasonable measures to reduce any additional amounts that would otherwise be payable to such Bank pursuant to this Section 2.24.

Section 2.25 Illegality. If any Regulatory Change shall make it unlawful or impossible for any Bank to make, maintain or fund any LIBOR Advances, such Bank shall notify the Borrower and the Agent, whereupon the obligation of such Bank to make or continue, or to convert any Advances to, LIBOR Advances shall be suspended until such Bank notifies the Borrower and the Agent that the circumstances giving rise to such suspension no longer exist. Before giving any such notice, such Bank shall designate a different Applicable Lending Office if such designation will avoid the need for giving such notice and will not, in the judgment of such Bank, be otherwise disadvantageous to such Bank. If such Bank determines that it may not lawfully continue to maintain any LIBOR Advances to the end of the applicable Interest Periods, all of the affected Advances shall be automatically converted to Prime Rate Advances as of the date of such Bank’s notice, and upon such conversion the Borrower shall indemnify such Bank in accordance with Section 2.27.

Section 2.26 Capital Adequacy. In the event that any Regulatory Change reduces or shall have the effect of reducing the rate of return on any Bank’s capital or the capital of its parent corporation (by an amount such Bank deems material) as a consequence of its Revolving Commitment and/or Advances and/or any Letters of Credit or any Bank’s obligations to make Advances to cover Letters of Credit to a level below that which such Bank or its parent corporation could have achieved but for such Regulatory Change (taking into account such Bank’s policies and the policies of its parent corporation with respect to capital adequacy), then the Borrower shall, within 30 days after written notice and demand from such Bank (with a copy to the Agent), pay to such Bank additional amounts sufficient to compensate such Bank or its parent corporation for such reduction. If any Bank fails to give such notice within 45 days after it obtains knowledge of such an event, such Bank shall, with respect to compensation payable pursuant to this Section, only be entitled to payment under this Section for diminished returns as a result of such reduction for the period from and after the date 45 days prior to the date that such

Bank does give such notice. Any determination by such Bank under this Section and any certificate as to the amount of such reduction given to the Borrower by such Bank shall be final, conclusive and binding for all purposes, absent error. Each of the Banks agrees that, as promptly as practicable after becoming aware of the occurrence of an event or the existence of a condition that would entitle such Bank to receive payments under this Section 2.26, it will, to the extent not inconsistent with the internal policies of such Bank and any applicable legal or regulatory restrictions, take reasonable measures to reduce any additional amounts that would otherwise be payable to such Bank pursuant to this Section 2.26.

Section 2.27 Funding Losses; LIBOR Advances. The Borrower shall compensate each Bank, upon its written request, for all losses, expenses and liabilities (including any interest paid by such Bank to lenders of funds borrowed by it to make or carry LIBOR Advances to the extent not recovered by such Bank in connection with the re-employment of such funds and including loss of anticipated profits) which such Bank may sustain: (i) if for any reason, other than a default by such Bank, a funding of a LIBOR Advance does not occur on the date specified therefor in the Borrower’s request or notice as to such Advance under Section 2.2 or 2.4, or (ii) if, for whatever reason (including, but not limited to, acceleration of the maturity of Advances following an Event of Default), any repayment of a LIBOR Advance, or a conversion pursuant to Section 2.4 or Section 2.25, occurs on any day other than the last day of the Interest Period applicable thereto. A Bank’s request for compensation shall set forth the basis for the amount requested and shall be final, conclusive and binding, absent error.

Section 2.28 Discretion of Banks as to Manner of Funding. Each Bank shall be entitled to fund and maintain its funding of LIBOR Advances in any manner it may elect, it being understood, however, that for the purposes of this Agreement all determinations hereunder (including, but not limited to, determinations under Section 2.27) shall be made as if such Bank had actually funded and maintained each LIBOR Advances during the Interest Period for such Advance through the purchase of deposits having a maturity corresponding to the last day of the Interest Period and bearing an interest rate equal to LIBOR for such Interest Period.

Section 2.29 Accordion Feature. The Borrower may, from time to time, increase the Aggregate Revolving Commitment Amount hereunder, by giving notice to the Agent, specifying the dollar amount of the increase (which shall be in an integral multiple of $5,000,000, and which shall not result in the Aggregate Revolving Commitment Amount hereunder exceeding $100,000,000); provided, however, that an increase in the Aggregate Revolving Commitment Amount 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 Aggregate Revolving Commitment Amount by either increasing a Revolving Commitment Amount with an existing Bank or obtaining a Revolving Commitment from a new financial institution, the selection of which shall require the consent of the Agent, not to be unreasonably withheld. The Borrower, the Agent and each Bank or other financial institution that is increasing its Revolving Commitment Amount or extending a new Revolving Commitment shall enter into an amendment to this Agreement setting forth the amounts of the Revolving Commitment Amount, as so increased, providing that any new financial institution extending a new Revolving Commitment shall be a Bank for all purposes under this Agreement. No such amendment shall require the approval or consent of any Bank whose Revolving Commitment Amount is not being increased and no Bank shall be required to increase its Revolving Commitment Amount 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 Revolving Loans of the Banks so that each Bank (including the Banks with new or increased Revolving Commitment) shall hold their respective Revolving Percentages (as amended by such amendment) of the Revolving Loans outstanding and the unfunded Revolving Commitment Amount (and each Bank shall so fund any increased amount of Advances), and shall participate in the Letter of Credit obligations and have obligations to participate in Unrefunded Swing Line Loans in their respective Revolving Percentages (as amended by such amendment).

Section 2.30 Late Funding by Banks. If 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, or if a Bank is required to fund a Swing Line Participation Amount under Section 2.5(b) or a risk participation in an Unpaid Drawing under Section 2.16 and fails to so fund by the time herein required, such Bank shall pay interest to the Agent on the amount so advanced at the overnight Federal Funds Rate (or if such funds are received by the Agent more than five (5) Business Days after such required funding interest at the rate then applicable to Revolving Loans) from the date of such funding requirement 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 amount of such funding. If such Bank pays the Agent the amount herein required with interest as provided above, such Bank shall be entitled to the interest payable by the Borrower with respect to the Revolving Loan, Swing Line Loan or Letter of Credit in question accruing during the period from the relevant funding by the Agent through funding by such Bank.

REPRESENTATIONS AND WARRANTIES

To induce the Banks to enter into this Agreement and to make Loans hereunder and to induce the Agent to issue Letters of Credit, the Borrower represents and warrants to the Banks:

Section 4.1 Organization, Standing, Etc. The Borrower is a corporation duly incorporated and validly existing and in good standing under the laws of the jurisdiction of its incorporation and has all requisite corporate power and authority to carry on its business as now conducted, to enter into this Agreement and to issue the Notes and to perform its obligations under the Loan Documents. Each Subsidiary is a corporation or a limited liability company duly

incorporated or organized and validly existing and in good standing under the laws of the jurisdiction of its incorporation or organization and has all requisite power and authority to carry on its business as now conducted. Each of the Borrower and the Subsidiaries (a) holds all certificates of authority, licenses and permits necessary to carry on its business as presently conducted in each jurisdiction in which it is carrying on such business, except where the failure to hold such certificates, licenses or permits would not have a material adverse effect on the business, operations, property, assets or condition, financial or otherwise, of the Borrower and the Subsidiaries taken as a whole, and (b) is duly qualified and in good standing or good status as a foreign corporation or limited liability company 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 the failure so to qualify would permanently preclude the Borrower or such Subsidiary from enforcing its rights with respect to any assets or expose the Borrower or such Subsidiary to any liability, which in either case would be material to the Borrower and the Subsidiaries taken as a whole.

Section 4.2 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 this Agreement constitutes, and the Notes and other Loan Documents when executed will 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 4.3 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 provision of the Certificate of Incorporation or bylaws 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 in which the consequences of such default or violation could have a material adverse effect on the business, operations, properties, assets or condition (financial or otherwise) of the Borrower and its Subsidiaries taken as a whole, or result in the creation of any Lien thereunder. Neither the Borrower nor any 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 could have a material adverse effect on the business, operations, properties, assets or condition (financial or otherwise) of the Borrower and its Subsidiaries taken as a whole.

Section 4.4 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 or its Subsidiaries 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.

Section 4.5 Financial Statements and Condition. The Borrower’s audited consolidated financial statements as at December 31, 2005 and its unaudited financial statements as at June 30, 2006, as heretofore furnished to the Banks, have been prepared in accordance with GAAP on a consistent basis (except for the absence of footnotes and subject to year-end audit adjustments as to the interim statements) and fairly present the financial condition of the Borrower and its Subsidiaries as at such dates and the results of their operations and changes in financial position for the respective periods then ended. As of the dates of such financial statements, neither the Borrower nor any Subsidiary had any material obligation, contingent liability, liability for taxes or long-term lease obligation which is not reflected in such financial statements or in the notes thereto. Since December 31, 2005, there has been no material adverse change in the business, operations, property, assets or condition, financial or otherwise, of the Borrower and its Subsidiaries taken as a whole.

Section 4.6 Litigation. There are no actions, suits or proceedings pending or, to the knowledge of the Borrower, threatened against or affecting the Borrower or any 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 Subsidiary, could reasonably be expected to have a material adverse effect on the business, operations, property or condition (financial or otherwise) of the Borrower and the Subsidiaries taken as a whole or on the ability of the Borrower or any Subsidiary to perform its obligations under the Loan Documents.

Section 4.7 Environmental, Health and Safety Laws. There does not exist any violation by the Borrower or any Subsidiary of any applicable federal, state or local law, rule or regulation or order of any government, governmental department, board, agency or other instrumentality relating to environmental, pollution, health or safety matters which could reasonably be expected to impose a material liability on the Borrower or a Subsidiary or to require a material expenditure by the Borrower or such Subsidiary to cure. Neither the Borrower nor any Subsidiary has received any notice to the effect that any part of its operations or properties is not in material compliance with any such law, rule, regulation or order or notice that it or its property is the subject of any governmental investigation evaluating whether any remedial action is needed to respond to any release of any toxic or hazardous waste or substance into the environment, which non-compliance or remedial action could reasonably be expected to have a material adverse effect on the business, operations, properties, assets or condition (financial or otherwise) of the Borrower and its Subsidiaries taken as a whole. The Borrower does not have knowledge that it or its property or any Subsidiary or the property of any Subsidiary will become subject to environmental laws or regulations during the term of this Agreement, compliance with which could reasonably be expected to require Capital Expenditures which would have a material adverse effect on the business, operations, properties, assets or condition (financial or otherwise) of the Borrower and its Subsidiaries taken as a whole.

Section 4.8 ERISA. Each Plan is in substantial compliance with all applicable requirements of ERISA and the Code and with all material applicable rulings and regulations issued under the provisions of ERISA and the Code setting forth those requirements. No Reportable Event has occurred and is continuing with respect to any Plan. All of the minimum funding standards applicable to such Plans have been satisfied and there exists no event or condition which would reasonably be expected to result in the institution of proceedings to

terminate any Plan under Section 4042 of ERISA. With respect to each Plan subject to Title IV of ERISA, as of the most recent valuation date for such Plan, the present value (determined on the basis of reasonable assumptions employed by the independent actuary for such Plan and previously furnished in writing to the Banks) of such Plan’s accumulated benefit obligations did not exceed the fair market value of such Plan’s assets by more than $50,000.

Section 4.9 Federal Reserve Regulations. Neither the Borrower nor any Subsidiary is engaged principally or as one of its important activities in the business of extending credit for the purpose of purchasing or carrying margin stock (as defined in Regulation U of the Board). The value of all margin stock owned by the Borrower does not constitute more than 25% of the value of the assets of the Borrower.

Section 4.10 Title to Property; Leases; Liens; Subordination. Each of the Borrower and the Subsidiaries has (a) good and marketable title to its real properties and (b) good and sufficient title to, or valid, subsisting and enforceable leasehold interest in, its other material properties, including all real properties, other properties and assets, referred to as owned by the Borrower and its Subsidiaries in the most recent financial statement referred to in Section 4.5 (other than property disposed of since the date of such financial statements except as allowed under Section 6.2). None of such properties is subject to a Lien, except as allowed under Section 6.14. The Borrower has not subordinated any of its rights under any obligation owing to it to the rights of any other person.

Section 4.11 Taxes. Each of the Borrower and the Subsidiaries has filed all federal, state and local tax returns required to be filed and has paid or made provision for the payment of all taxes due and payable pursuant to such returns and pursuant to any assessments made against it or any of its property and all other taxes, fees and other charges imposed on it or any of its property by any governmental authority (other than taxes, fees or charges the amount or validity of which is currently being contested in good faith by appropriate proceedings and with respect to which reserves in accordance with GAAP have been provided on the books of the Borrower). No tax Liens have been filed and no material claims are being asserted with respect to any such taxes, fees or charges. The charges, accruals and reserves on the books of the Borrower in respect of taxes and other governmental charges are adequate and the Borrower knows of no proposed material tax assessment against it or any Subsidiary or any basis therefor.

Section 4.12 Trademarks, Patents. Each of the Borrower and the Subsidiaries possesses or has the right to use all of the patents, trademarks, trade names, service marks and copyrights, and applications therefor, and all technology, know-how, processes, methods and designs used in or necessary for the conduct of its business, without known conflict with the rights of others.

Section 4.13 Burdensome Restrictions. Neither the Borrower nor any Subsidiary is a party to or otherwise bound by any indenture, loan or credit agreement or any lease or other agreement or instrument or subject to any charter, corporate or partnership restriction which would foreseeably have a material adverse effect on the business, properties, assets, operations or condition (financial or otherwise) of the Borrower or such Subsidiary or on the ability of the Borrower or any Subsidiary to carry out its obligations under any Loan Document.

Section 4.14 Force Majeure. Since the date of the most recent financial statement referred to in Section 4.5, the business, properties and other assets of the Borrower and the Subsidiaries have not been materially and adversely affected in any way as the result of any fire or other casualty, strike, lockout, or other labor trouble, embargo, sabotage, confiscation, condemnation, riot, civil disturbance, activity of armed forces or act of God.

Section 4.15 Investment Company Act. Neither the Borrower nor any Subsidiary is an “investment company” or a company “controlled” by an investment company within the meaning of the Investment Company Act of 1940, as amended.

Section 4.16 Retirement Benefits. Except as required under Section 4980B of the Code, Section 601 of ERISA or applicable state law, neither the Borrower nor any Subsidiary is obligated to provide post-retirement medical or insurance benefits with respect to employees or former employees in an aggregate amount exceeding $50,000.

Section 4.17 Subsidiaries. The Borrower’s Subsidiaries are listed on Schedule 4.17.

ARTICLE 8

THE AGENT

The following provisions shall govern the relationship of the Agent with the Banks.

Section 8.1 Appointment and Authorization. Each Bank appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such respective powers under the Loan Documents as are delegated to the Agent by the terms thereof, together with such powers as are reasonably incidental thereto. Neither the Agent nor any of its directors, officers or employees shall be liable for any action taken or omitted to be taken by it under or in connection with the Loan Documents, except for its own gross negligence or willful misconduct. The Agent shall act as an independent contractor in performing its obligations as Agent hereunder and nothing herein contained shall be deemed to create any fiduciary relationship among or between the Agent, the Borrower or the Banks.

Section 8.5 U.S. Bank and Affiliates. With respect to its Commitments and the Loans made by it, U.S. Bank shall have the same rights and powers under the Loan Documents as any other Bank and may exercise the same as though it were not the Agent consistent with the terms thereof, and U.S. Bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower as if it were not the Agent.

Section 8.6 Action by Agent. Except as may otherwise be expressly stated in this Agreement, the Agent shall be entitled to use its discretion with respect to exercising or refraining from exercising any rights which may be vested in it by, or with respect to taking or refraining from taking any action or actions which it may be able to take under or in respect of, the Loan Documents. The Agent shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Required Banks, and such instructions shall be binding upon all holders of Notes; provided, however, that the Agent shall not be required to take any action which exposes the Agent to personal liability or which is contrary to the Loan Documents or applicable law. The Agent shall incur no liability under or in respect of any of the Loan Documents by acting upon any notice, consent, certificate,

warranty or other paper or instrument believed by it to be genuine or authentic or to be signed by the proper party or parties and to be consistent with the terms of this Agreement.

Section 8.7 Credit Analysis. Each Bank has made, and shall continue to make, its own independent investigation or evaluation of the operations, business, property and condition, financial and otherwise, of the Borrower in connection with entering into this Agreement and has made its own appraisal of the creditworthiness of the Borrower. Except as explicitly provided herein, the Agent has no duty or responsibility, either initially or on a continuing basis, to provide any Bank with any credit or other information with respect to such operations, business, property, condition or creditworthiness, whether such information comes into its possession on or before the first Event of Default or at any time thereafter.

Section 8.8 Notices of Event of Default, Etc. In the event that the Agent shall have acquired actual knowledge of any Event of Default or Default, the Agent shall promptly give notice thereof to the Banks.

Section 8.9 Indemnification. Each Bank agrees to indemnify the Agent, as Agent (to the extent not reimbursed by the Borrower), ratably according to such Bank’s share of the aggregate Revolving Commitment Amounts from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on or incurred by the Agent in any way relating to or arising out of the Loan Documents or any action taken or omitted by the Agent under the Loan Documents, provided that no Bank shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Agent’s gross negligence or willful misconduct. No payment by any Bank under this Section shall relieve the Borrower of any of its obligations under this Agreement.

Section 8.10 Payments and Collections. All funds received by the Agent in respect of any payments made by the Borrower on the Notes, Revolving Commitment Fees or Letter of Credit Fees shall be distributed forthwith by the Agent among the Banks, in like currency and funds as received, ratably according to each Bank’s Revolving Percentage (except for payments of the Swing Line Notes, which shall be paid to the Swing Line Bank). After any Event of Default has occurred, all funds received by the Agent, whether as payments by the Borrower or as realization on collateral, shall (except as may otherwise be required by law) be distributed by the Agent in the following order: (a) first to the Agent or any Bank who has incurred unreimbursed costs of collection with respect to any Obligations hereunder, ratably to the Agent and each Bank in the proportion that the costs incurred by the Agent or such Bank bear to the total of all such costs incurred by the Agent and all Banks; (b) next to the Agent for the account of the Banks (in accordance with their respective Revolving Percentages) for application on the Revolving Notes; (c) next to the Agent for the account of the Banks (in accordance with their respective Revolving Percentages) for any unpaid Revolving Commitment Fees or Letter of Credit Fees owing by the Borrower hereunder; and (d) last to the Agent to be held in the Holding Account to cover any outstanding Letters of Credit, provided, however, that if any Bank shall not have funded its Swing Line Participation Amount, as provided in Section 2.5(b), or funded a required purchase of a risk participation in an Unpaid Drawing as provided in Section 2.16, any

amounts otherwise payable to such Bank in accordance with this Section shall be applied to such funding requirements prior to any payment being made to such Bank.

Section 8.11 Sharing of Payments. If any Bank shall receive and retain any payment, voluntary or involuntary, whether by setoff, application of deposit balance or security, or otherwise, in respect of Indebtedness under this Agreement or the Revolving Notes in excess of such Bank’s share thereof as determined under this Agreement, then such Bank shall purchase from the other Banks for cash and at face value and without recourse, such participation in the Revolving Notes held by such other Banks as shall be necessary to cause such excess payment to be shared ratably as aforesaid with such other Banks; provided, that if such excess payment or part thereof is thereafter recovered from such purchasing Bank, the related purchases from the other Banks shall be rescinded ratably and the purchase price restored as to the portion of such excess payment so recovered, but without interest. Subject to the participation purchase obligation above, each Bank agrees to exercise any and all rights of setoff, counterclaim or banker’s lien first fully against any Revolving Notes and participations therein held by such Bank, next to any other Indebtedness of the Borrower to such Bank arising under or pursuant to this Agreement and to any participations held by such Bank in Indebtedness of the Borrower arising under or pursuant to this Agreement, and only then to any other Indebtedness of the Borrower to such Bank.

Section 8.12 Resignation. If at any time U.S. Bank shall deem it advisable, in its sole discretion, it may submit to each of the Banks and the Borrower a written notification of its resignation as Agent under this Agreement, such resignation to be effective upon the appointment of a successor Agent, but in no event later than 30 days from the date of such notice.

(The Agent may enter into amendments or modifications of, and grant consents and waivers to departure from the provisions of, those Loan Documents to which the Banks are not signatories without the Banks joining therein, provided the Agent has first obtained the separate prior written consent to such amendment, modification, consent or waiver from the Required Banks.)

Whether or not the transactions contemplated hereby are consummated, the Borrower agrees to reimburse the Agent upon demand for all reasonable out-of-pocket expenses paid or incurred by the Agent (including filing and recording costs and fees and expenses of counsel to the Agent) in connection with the negotiation, preparation, approval, review, execution, delivery, administration, amendment, modification and interpretation of this Agreement and the other Loan Documents and any commitment letters relating thereto. The Borrower shall also reimburse the Agent and each Bank upon demand for all reasonable out-of-pocket expenses (including expenses of legal counsel) paid or incurred by the Agent or any Bank in connection with the collection and enforcement of this Agreement and any other Loan Document. The obligations of the Borrower under this Section shall survive any termination of this Agreement.

Section 9.3 Waivers, etc. No failure on the part of the Agent or the holder of a Note 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 the other Loan Documents provided are cumulative and not exclusive of any remedies provided by law.

Section 9.4 Notices. Except when telephonic notice is expressly authorized by this Agreement, any notice or other communication to any party in connection with this Agreement shall be in writing and shall be sent by manual delivery, facsimile transmission, overnight courier or United States mail (postage prepaid) addressed to such party at the address specified on the signature page hereof, or at such other address as such party shall have specified to the other party hereto in writing. All periods of notice shall be measured from the date of delivery thereof if manually delivered, from the date of sending thereof if sent by facsimile transmission, from

the first Business Day after the date of sending if sent by overnight courier, or from four days after the date of mailing if mailed; provided, however, that any notice to the Agent or any Bank under Article 2 hereof shall be deemed to have been given only when received by the Agent or such Bank.

Section 9.5 Taxes. The Borrower agrees to pay, and save the Agent and the Banks harmless from all liability for, any stamp or other taxes which may be payable with respect to the execution or delivery of this Agreement or the issuance of the Notes, which obligation of the Borrower shall survive the termination of this Agreement.

Section 9.6 Successors and Assigns; Disposition of Loans; Transferees. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, except that the Borrower may not assign its rights or delegate its obligations hereunder or under any other Loan Documents without the prior written consent of all the Banks. Each Bank may at any time sell, assign, transfer, grant participations in, or otherwise dispose of any portion (in a minimum amount of $10,000,000) of its Revolving Commitments, the Revolving Loans and/or Advances (each such interest so disposed of being herein called a “Transferred Interest”) to banks or other financial institutions (“Transferees”); provided, however, that a Bank may dispose of a Transferred Interest only with the consents of the Agent and the Borrower (which consents shall not be unreasonably withheld) and only upon payment to the Agent by the Banks party to such disposition of a processing and recording fee in the amount of $3,000 for each party. Notwithstanding the preceding sentence, a Bank may dispose of a Transferred Interest without consent of the borrower if an Event of Default has occurred and is continuing. The Borrower agrees that each Transferee shall be entitled to the benefits of this Agreement with respect to its Transferred Interest and that each Transferee may exercise any and all rights of banker’s Lien, setoff and counterclaim as if such Transferee were a direct lender to the Borrower. If any Bank makes any assignment to a Transferee, then upon notice to the Borrower such Transferee, to the extent of such assignment (unless otherwise provided therein), shall become a “Bank” hereunder and shall have all the rights and obligations of such Bank hereunder and such Bank shall be released from its duties and obligations under this Agreement to the extent of such assignment. Notwithstanding the sale by any Bank of any participation hereunder, (a) no participant shall be deemed to be or have the rights and obligations of a Bank hereunder except that any participant shall have a right of setoff under Section 7.3 as if it were such Bank and the amount of its participation were owing directly to such participant by the Borrower and (b) such Bank shall not in connection with selling any such participation condition such Bank’s rights in connection with consenting to amendments or granting waivers concerning any matter under any Loan Document upon obtaining the consent of such participant other than on matters relating to (i) any reduction in the amount of any principal of, or the amount of or rate of interest on, any Revolving Note or Advance in which such participation is sold, (ii) any postponement of the date fixed for any payment of principal of or interest on any Revolving Note or Advance in which such participation is sold, or (iii) the release of any guaranty. No Bank shall be permitted to enter into any assignment or participation with any Transferee who is not a United States Person unless such Transferee represents and warrants to such Bank that, as at the date of such assignment of participation, it is entitled to receive interest payments without withholding or deduction of any taxes and such Transferee executes and delivers to such Bank on or before the date of execution and delivery of documentation of such participation or assignment, a United States Internal Revenue Service Form W8-BEN or W-8ECI,

or any successor to either of such forms, as appropriate, properly completed and 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 or fees hereunder.

Section 9.7 Confidentiality of Information. The Agent and each Bank shall use reasonable efforts to assure that information about the Borrower and its operations, affairs and financial condition, not generally disclosed to the public or to trade and other creditors, which is furnished to the Agent or such Bank pursuant to the provisions hereof is used only for the purposes of this Agreement and any other relationship between any Bank and the Borrower and shall not be divulged to any Person other than the Banks, their Affiliates and their respective officers, directors, employees and agents, except: (a) to their attorneys and accountants, (b) in connection with the enforcement of the rights of the Banks hereunder and under the Notes or otherwise in connection with applicable litigation, (c) in connection with assignments and participations and the solicitation of prospective assignees and participants referred to in the immediately preceding Section, and (d) as may otherwise be required or requested by any regulatory authority having jurisdiction over any Bank or by any applicable law, rule, regulation or judicial process, the opinion of such Bank’s counsel concerning the making of such disclosure to be binding on the parties hereto. No Bank shall incur any liability to the Borrower by reason of any disclosure permitted by this Section 9.7.

Section 9.8 Governing Law and Construction. THE VALIDITY, CONSTRUCTION AND ENFORCEABILITY OF THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY THE INTERNAL LAWS OF THE STATE OF MINNESOTA, WITHOUT GIVING EFFECT TO CONFLICT OF LAWS PRINCIPLES THEREOF, BUT GIVING EFFECT TO FEDERAL LAWS OF THE UNITED STATES APPLICABLE TO NATIONAL BANKS. Whenever possible, each provision of this Agreement and the other Loan Documents and any other statement, instrument or transaction contemplated hereby or thereby or relating hereto or thereto shall be interpreted in such manner as to be effective and valid under such applicable law, but, if any provision of this Agreement, the other Loan Documents or any other statement, instrument or transaction contemplated hereby or thereby or relating hereto or thereto shall be held to be prohibited or invalid under such applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement, the other Loan Documents or any other statement, instrument or transaction contemplated hereby or thereby or relating hereto or thereto.

Section 9.9 Consent to jurisdiction. AT THE OPTION OF THE AGENT, THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS MAY BE ENFORCED IN ANY FEDERAL COURT OR MINNESOTA STATE COURT SITTING IN HENNEPIN COUNTY, MINNESOTA; AND THE BORROWER CONSENTS TO THE JURISDICTION AND VENUE OF ANY SUCH COURT AND WAIVES ANY ARGUMENT THAT VENUE IN SUCH FORUMS IS NOT CONVENIENT. IN THE EVENT THE BORROWER COMMENCES ANY ACTION IN ANOTHER JURISDICTION OR VENUE UNDER ANY TORT OR CONTRACT THEORY ARISING

DIRECTLY OR INDIRECTLY FROM THE RELATIONSHIP CREATED BY THIS AGREEMENT, THE AGENT AT ITS OPTION SHALL BE ENTITLED TO HAVE THE CASE TRANSFERRED TO ONE OF THE JURISDICTIONS AND VENUES ABOVE-DESCRIBED, OR IF SUCH TRANSFER CANNOT BE ACCOMPLISHED UNDER APPLICABLE LAW, TO HAVE SUCH CASE DISMISSED WITHOUT PREJUDICE.

Section 9.10 Waiver of Jury Trial. EACH OF THE BORROWER, THE AGENT AND THE BANKS IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

Section 9.12 Indemnification. The Borrower hereby agrees to defend, protect, indemnify and hold harmless the Agent and the Banks and their respective Affiliates and the directors, officers, employees, attorneys and agents of the Agent and the Banks and their respective Affiliates (each of the foregoing being an “Indemnitee” and all of the foregoing being collectively the “Indemnitees”) from and against any and all claims, actions, damages, liabilities, judgments, costs and expenses (including all reasonable fees and disbursements of counsel which may be incurred in the investigation or defense of any matter) imposed upon, incurred by or asserted against any Indemnitee, whether direct, indirect or consequential and whether based on any federal, state, local or foreign laws or regulations (including securities laws, environmental laws, commercial laws and regulations), under common law or on equitable cause, or on contract or otherwise:

(a) by reason of, relating to or in connection with the execution, delivery, performance or enforcement of any Loan Document, any commitments relating thereto, or any transaction contemplated by any Loan Document; or

(b) by reason of, relating to or in connection with any credit extended or used under the Loan Documents or any act done or omitted by any Person, or the exercise of any rights or remedies thereunder, including the acquisition of any collateral by the Banks by way of foreclosure of the Lien thereon, deed or bill of sale in lieu of such foreclosure or otherwise;

provided, however, that the Borrower shall not be liable to any Indemnitee for any portion of such claims, damages, liabilities and expenses resulting from such Indemnitee’s gross negligence

or willful misconduct. In the event this indemnity is unenforceable as a matter of law as to a particular matter or consequence referred to herein, it shall be enforceable to the full extent permitted by law.

This indemnification applies, without limitation, to any act, omission, event or circumstance existing or occurring on or prior to the later of the Termination Date or the date of payment in full of the Obligations, including specifically Obligations arising under clause (b) of this Section. The indemnification provisions set forth above shall be in addition to any liability the Borrower may otherwise have. Without prejudice to the survival of any other obligation of the Borrower hereunder the indemnities and obligations of the Borrower contained in this Section shall survive the payment in full of the other Obligations.

Section 9.17 Patriot Act. Each Bank hereby notifies the Borrower that pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Bank to identify the Borrower in accordance with the Patriot Act.

Form of Legal Opinion

August 31, 2006

To the Financial Institutions

Party to the Credit Agreement

Referred to Below

and U.S. Bank National Association, as Agent

800 Nicollet Mall

Mail Code BC-MN-H03

Minneapolis, Minnesota 55402

Ladies and Gentlemen:

We have acted as counsel to Marten Transport, Ltd., a Delaware corporation, as the borrower (the “Borrower”), in connection with its execution, delivery, and performance under the following documents:

(i) that certain Credit Agreement, dated as of August 31, 2006, entered into by and among the Borrower, the lenders party thereto (the “Banks”), and U.S. Bank National Association, as agent (the “Agent”) for the Banks (the “Credit Agreement”);

(ii) those certain Revolving Notes, each dated as of August 31, 2006, made by the Borrower in favor of each of the Banks (the “Revolving Notes”);

(iii) that certain Swing Line Note, dated as of August 31, 2006, made by the Borrower in favor of the Agent (the “Swing Line Note”); and

(iv) that certain fee letter agreement, dated as of August 31, 2006, entered into by and between the Borrower and the Agent (the “Fee Letter”).

Capitalized terms used herein but not otherwise defined herein shall have the respective meanings ascribed to such terms in the Credit Agreement.

We have examined originals, or copies certified or otherwise identified to our satisfaction, of (i) the Credit Agreement; (ii) the Revolving Notes; (iii) the Swing Line Note; and (iv) the Fee Letter (the aforementioned documents are collectively referred to herein as the “Loan Documents”).

In rendering our opinions herein, we have examined the certificate of incorporation and bylaws of the Borrower as in effect on the date hereof. We also have examined such certificates of public officials, including certain certificates of good standing and certificates relating to foreign qualifications, corporate documents and records and other certificates, opinions and instruments, and have made such other investigation, as we have deemed necessary in connection with this opinion. As to questions of fact relevant to this opinion, without any independent investigation or verification, we have relied upon, and assumed the accuracy of, the representations and warranties of each party as to factual matters thereto and have relied upon certificates of officers of the Borrower and written statements of certain public officials.

In rendering this opinion, we have assumed:

(a) the genuineness of all signatures, the legal capacity of all natural Persons, the authenticity of all documents submitted to us as originals and the conformity to originals of all documents submitted to us as certified or photostatic copies; and

(b) that each of the Loan Documents has been duly executed and delivered by each of the parties thereto other than the Borrower, and that each of such parties other than the Borrower has the corporate power and authority to enter into and perform such Loan Documents.

We also wish to advise you of the following:

A. We are specifically providing no opinion regarding whether (1) franchise, income, sales, gross receipts, profits or other like taxes are payable in the State of Minnesota by any party that may seek to enforce the Loan Documents against the Borrower (an “Enforcing Party”) under Minnesota law or in Minnesota courts; or (2) an Enforcing Party is required to file a business activity report pursuant to Minnesota Statutes Section 290.371 (“Business Activity Report”). Failure to comply with the Business Activity Report requirement, if applicable, prevents an out-of-state entity from using the courts in Minnesota for all contracts executed at any time before the end of the period for which the entity failed to file such required report and the entity does not have cause of action on which it may bring suit in the State of Minnesota. If the entity subsequently files the report and pays all taxes, interest and civil penalties due, the courts in which the issues arise must excuse non-compliance with the Business Activity Report filing requirement.

B. No foreign corporation may transact business in the State of Minnesota unless it holds a Certificate of Authority to do so. Without excluding other activities which may not constitute transacting business in the State of Minnesota, a foreign corporation shall not be considered to be transacting business in the State of Minnesota solely by reason of the corporation making, participating in or investing in loans or creating, as borrower or lender, or otherwise acquiring indebtedness or mortgage or other security interests in real or personal property or securing or collecting its debts or enforcing any rights in property securing them. Hence, to the extent that the actions of a lender are limited strictly to the above, it will not be necessary for the lender to qualify as a foreign corporation and obtain a Certificate of Authority. The statutory exception to the necessity to qualify does not go to a corporation whose other activities in the State of Minnesota would require qualification.

Upon the basis of the foregoing, we are of the opinion that, under applicable law in effect on the date of this opinion:

1. The Borrower is a corporation duly organized, validly existing, and in good standing under the laws of the State of Delaware. The Borrower is duly qualified to do business and is in good standing or good status as a foreign corporation in each jurisdiction set forth on Exhibit A hereto.

2. The Borrower has full corporate power and authority to own and operate its properties and assets, carry on its business as presently conducted, and enter into and perform its obligations under the Loan Documents.

3. The execution and delivery of the Loan Documents, the performance by the Borrower of its obligations under the Loan Documents, and the borrowing by the Borrower under the Credit Agreement, have been duly authorized by all necessary corporate action, and each of the Loan Documents have been duly executed and delivered by the Borrower, and each of such Loan Documents constitutes the valid and binding obligation of the Borrower, enforceable in accordance with its respective terms.

4. The execution and delivery by the Borrower of the Loan Documents and the performance by the Borrower of its obligations under such Loan Documents, each in accordance with its respective terms, do not conflict with the Certificate of Incorporation or the Bylaws of the Borrower. The execution and delivery by the Borrower of the Loan Documents and the performance by the Borrower of its obligations under such Loan Documents, each in accordance with its terms, do not constitute a violation of or a default under any material contract or other material agreement or instrument to which the Borrower is a party that is listed as an exhibit to the Borrower’s Annual Report on Form 10-K for the year ended December 31, 2005 (except that we express no opinion with respect to compliance with financial covenants or tests).

5. The execution and delivery by the Borrower of the Loan Documents and the performance by the Borrower of its obligations under such Loan Documents, each in accordance with its terms, do not violate any provision of applicable law, statute, rule, or regulation (other than state securities and blue sky laws, as to which we express no opinion and except that any right to indemnity and contribution may be limited by federal and state securities laws and public policy considerations) that we, based on our experience, recognize as applicable to the Borrower in a transaction of this type.

6. The execution and delivery by the Borrower of the Loan Documents and the performance by the Borrower of its obligations under such Loan Documents, each in accordance with its terms, do not, to our knowledge, contravene any writ, order or decree of any governmental instrumentality that has jurisdiction over the Borrower.

7. To our knowledge, there are no actions, suits, or proceedings pending or overtly threatened in writing against the Borrower before any court or arbitrator or by or before any administrative agency or governmental authority, which, if adversely determined, could reasonably be expected to have a material adverse effect on the business or operations of the Borrower.

8. No consent or approval of any governmental instrumentality, which has not been obtained or taken and is not in full force and effect, is required in connection with (i) the execution or performance of any of the Loan Documents by the Borrower, or (ii) any borrowings that may be requested from time to time by the Borrower pursuant to the terms of the Credit Agreement except as may be required to be made or obtained by the Banks or the Agent as a result of their involvement in the transactions contemplated by the Loan Documents.

9. The Borrower is not an “investment company” or a company “controlled” by an “investment company,” as such terms are defined in the Investment Company Act of 1940, as amended.

10. To our knowledge, the Borrower is not engaged in the business of extending credit for the purpose of purchasing or carrying margin stock within the meaning of Regulation U of the Board of Governors of the Federal Reserve System, and, to our knowledge, no portion of the proceeds of the Loans will be used (i) to purchase or carry margin stock or (ii) to extend credit to others for the purpose of purchasing or carrying any margin stock.

The opinions set forth above are subject to the following qualifications:

a. The opinions expressed herein are based upon and limited to matters governed by: (i) the laws of the State of Minnesota, (ii) the corporate laws of the State of Delaware, and (iii) the federal laws of the United States of America. We assume no responsibility as to the applicability thereto, or the effect thereon, and we expressly exclude from this opinion, the laws of any other jurisdiction.

b. The enforceability of the Loan Documents against the Borrower may be limited by bankruptcy, insolvency, fraudulent conveyance, fraudulent transfer, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and by general equitable principles (regardless of whether enforcement is sought in equity or at law), including, without limitation, principles regarding good faith and fair dealing. In addition, we express no opinion as to the enforceability of (i) provisions relating to the availability of specific remedies or relief, including indemnification and contribution, or the release or waiver of any remedies or rights or time periods in which claims are required to be asserted, (ii) provisions that allow cumulative remedies, late charges or default interest, or (iii) provisions relating to choice of forum.

c. Where we render an opinion based upon factual matters “known to us,” “to our knowledge,” “to the best of our knowledge” or similar language, it is based solely upon inquiries of this firm’s attorneys who have worked on the above described transactions, an examination of documents made available to us by the Borrower, and inquiries of officers of the Borrower. We have relied on written statements of officers of the Borrower covering certain of such matters.

The opinions set forth herein are solely for your benefit and the benefit of your legal counsel, assignees and participants, and you and your counsel, assignees, participants, and agents of the foregoing hereby are authorized to rely on such opinions. The opinions set forth herein may not be relied upon by, and copies of such opinion may not be delivered to, any other person without the prior written consent of the undersigned. This opinion is given only as of the date hereof and we expressly disclaim any duty to update the statements made herein.

Very truly yours,
