Within the above limits, the Borrower may obtain Revolving Advances, prepay Revolving Advances in accordance with the terms hereof and reborrow Revolving Advances in accordance with the applicable terms and conditions of this Agreement.

(b)    Revolving Borrowing Procedures. Each Revolving Borrowing shall be funded by the Revolving Lenders as either an ABR Borrowing or a LIBOR Borrowing, as the Borrower shall specify in the related notice of proposed Borrowing. ABR Loans and LIBOR Loans may be outstanding at the same time. The principal amount of any Revolving Borrowing shall be in an amount equal to (i) $1,000,000 or a higher integral multiple of $500,000 if such Borrowing is funded as an ABR Borrowing, and (ii) $5,000,000 or a higher integral multiple of $1,000,000 if such Borrowing is funded as a LIBOR Borrowing. The Borrower shall give notice to the Administrative Agent of each proposed Revolving Borrowing not later than 12:00 noon on a Business Day that, in the case of an ABR Borrowing, is the proposed date of such Borrowing or, in the case of a Borrowing that is to bear interest initially at an Adjusted LIBO Rate, is at least 3 Business Days prior to the proposed date of such Borrowing. Each such notice shall be effective upon receipt by the Administrative Agent, shall be provided in writing or in such other manner as the Administrative Agent and the Borrower may agree (to be confirmed in writing by the Borrower if so requested by the Administrative Agent), and shall specify whether the Borrowing is to be an ABR Borrowing or a LIBOR Borrowing and, in the case of a LIBOR Borrowing, shall specify the Interest Period to be applicable thereto. Promptly upon receipt of such notice (but in no event later than 1:00 p.m. with respect to an ABR Borrowing, and the close of business, with respect to a LIBOR Borrowing, in each case on the Business Day of receipt of such notice), the Administrative Agent shall advise each Lender of the proposed Borrowing. Subject to satisfaction of the conditions precedent set forth in Article III with respect to such Borrowing, at or before 1:00 p.m. on the date of the requested Borrowing, each Revolving Lender shall provide the Administrative Agent at the principal office of the Administrative Agent in Charlotte, North Carolina (or such other office as the Administrative Agent may designate), with immediately available funds covering such Revolving Lender’s Revolving Percentage of such Borrowing. The

Administrative Agent shall pay over proceeds of such Borrowing to the Borrower, in immediately available funds, prior to the close of business on the date of the requested Borrowing.

(c)    Limitation. Notwithstanding any other provision of this Agreement to the contrary, no Borrowing shall be effected on any anniversary of this Agreement.

So long as no Default or Event of Default has occurred and is continuing, the Borrower may convert all or any part of any outstanding ABR Loan into a LIBOR Loan by giving notice to the Administrative Agent of such conversion not later than 9:00 a.m. on a Business Day that is at least 2 Business Days prior to the date of the requested conversion. Each such notice shall be irrevocable, shall be effective upon receipt by the Administrative Agent, shall be provided in writing or in such other manner as the Administrative Agent and the Borrower may agree (to be confirmed in writing by the Borrower if so requested by the Administrative Agent), shall specify the date and amount of such conversion, the total amount of the Loan to be so converted and the Interest Period therefor. Each conversion of a Loan shall be on a Business Day, and the aggregate amount of each such conversion of an ABR Loan to a LIBOR Loan shall be in an amount equal to $5,000,000 or a higher integral multiple of $1,000,000. The Administrative Agent shall promptly (but in no event later than the close of business on the day received) forward such notice to the applicable Lenders.

Unless the Borrower requests a new LIBOR Loan in accordance with the procedures set forth below, or prepays the principal of an outstanding LIBOR Loan at the expiration of an Interest Period, each Lender shall automatically and without request of the Borrower convert each LIBOR Loan to an ABR Loan on the last day of the relevant Interest Period. So long as no Default or Event of Default has occurred and is continuing, the Borrower may cause all or any part of any outstanding LIBOR Loan to continue as a LIBOR Loan after the end of the then applicable Interest Period by notifying the Administrative Agent not later than 9:00 a.m. on a Business Day that is at least 2 Business Days prior to the first day of the new Interest Period. Each such notice shall be irrevocable, effective when received by the Administrative Agents, shall be provided in writing or in such other manner as the Administrative Agent and the Borrower may agree (to be confirmed in writing by the Borrower if so requested by the Administrative Agent) and shall specify the first day of the applicable Interest Period, the amount of the expiring LIBOR Loan to be continued and the Interest Period therefor. The Administrative Agent shall promptly (but in no event later than the close of business on the day received) forward such notice to the applicable Lenders. Each new Interest Period shall begin on a Business Day and the amount of each LIBOR Loan shall be in an amount equal to $5,000,000 or a higher integral multiple of $1,000,000.

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

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

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

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

(c)    The Margins at any time shall be determined from time to time on the basis of the Borrower’s Level Status, in accordance with the following table:

The Borrower will pay interest on the unpaid principal amount of each Loan for the period commencing on the date of this Agreement until the unpaid principal amount thereof is paid in full, in accordance with the following:

(a)    ABR Loans. Subject to subsection (c) below, while any outstanding principal of a Loan constitutes an ABR Loan, the outstanding principal balance thereof shall bear interest at an annual rate at all times equal to the Adjusted Base Rate, plus the applicable Margin.

(b)    LIBOR Loans. Subject to subsection (c) below, while any outstanding principal of a Loan constitutes a LIBOR Loan, the outstanding principal balance thereof shall bear interest at an annual rate equal to the Adjusted LIBO Rate established with respect to such LIBOR Loan in accordance with Section 2.1, 2.2 or 2.3, plus the applicable Margin.

(c)    Default Rate. From and after the occurrence of any Event of Default under paragraph (a), (b), (g) or (h) of Section 7.1, and from and after written notice from the Administrative Agent (or the Required Lenders) to the Borrower following the occurrence of any other Event of Default, and continuing (in each case) thereafter until such Event of Default is cured or waived to the written satisfaction of the Required Lenders, the outstanding principal balance of each Loan shall bear interest, until paid in full, at an annual rate equal to the sum of (i) the interest rate otherwise in effect with respect to such outstanding principal and (ii) 200 basis points. In addition, all fees, indemnification obligations and other Obligations not paid when due hereunder shall bear interest, until paid in full, at an annual rate equal to the sum of (x) the Adjusted Base Rate, (y) the Margin then applicable to ABR Loans, and (z) 200 basis points (each rate described in this subsection (c) herein, a “Default Rate”).

(d)    Savings Clause. Notwithstanding anything in this Section 2.6 to the contrary, at no time shall the Borrower be obligated or required to pay interest on any Obligation at a rate which could subject any Lender to either civil or criminal liability as a result of being in excess of the maximum interest rate which the Borrower is permitted by applicable law, including all applicable usury laws and Authorizing Orders. If, under the terms of this Agreement or any other Loan Document, the Borrower is at any time required or obligated to pay interest on any Obligation at a rate in excess of such maximum rate, the applicable interest rate shall be deemed to be immediately reduced to such maximum rate and all previous payments in excess of the maximum rate shall be deemed to have been payments in reduction of principal and not on account of any interest thereon due hereunder. All sums paid or agreed to be paid to a Lender for the use, forbearance or retention of any Obligation, shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full stated term of the Obligation

to which such payment applies until payment in full so that the rate or amount of interest on account of any such Obligation does not exceed the maximum lawful rate of interest from time to time in effect and applicable to such Obligation for so long as the Obligation is outstanding.

The Borrower shall be obligated to repay all Advances under this Article II notwithstanding the failure of the Administrative Agent to receive from the Borrower any written request therefor or written confirmation thereof and notwithstanding the fact that the Person requesting the same was not in fact authorized to do so. Any request for a Credit Extension, whether written, telephonic, telecopy or otherwise, shall be deemed to be a representation by the Borrower that the statements set forth in Section 3.2 are correct as of the time of the request.

(a)    Interest. The Borrower shall pay accrued but unpaid interest on each Loan on each Interest Payment Date with respect to that Loan.

(b)    Revolving Facility Principal. The Borrower shall pay the principal balance of all Revolving Borrowings then outstanding in full on each Principal Payment Date.

(c)    Maintenance of Records. Each Lender shall maintain in accordance with its usual practice records evidencing the indebtedness of the Borrower to such Lender resulting from the Advances made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder. The Administrative Agent shall maintain in accordance with its usual practice the Register and such other records as it deems appropriate in which it shall record (i) the amount of each Advance hereunder, (ii) the amount of each Loan hereunder and, if applicable, the Interest Period with respect thereto, (iii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder, and (iv) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof. The entries made in the records maintained pursuant to this paragraph (c) shall be prima facie evidence of the matters recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such records or any error therein shall not in any manner affect the obligation of a Borrower to repay the Obligations in accordance with the terms of this Agreement.

(d)    Promissory Notes Optional. The Borrower’s obligation to repay the principal of and interest on the Advances made by each Lender shall be evidenced in the Register and shall, if requested by such Lender, also be evidenced by a Revolving Note, duly executed and delivered by the Borrower, with blanks appropriately completed, with respect to Revolving Advances made by such Lender.

Interest accruing on the Loans, and all Facility Fees and other fees described in Section 2.10, shall be computed on the basis of the actual number of days elapsed in a year of 360 days; provided, however, that interest accruing from time to time on ABR Loans bearing interest determined by reference to the Base Rate shall be computed on the basis of the actual number of days elapsed in a year of 365 or 366 days, as the case may be.

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

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

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

The proceeds of the initial Borrowing hereunder shall be used to pay in full all obligations of the Borrower outstanding under the Existing Credit Facility, if any. The proceeds of each other Credit Extension (including the initial Borrowing, if no obligations described in the preceding sentence are outstanding on the date thereof) shall be used solely (i) to pay the Borrower’s obligations under (A) its commercial paper program, (B) other short-term credit facilities, and (C) maturing long-term obligations, and (ii) for the general corporate purposes of the Borrower in the ordinary course of business.

The Borrower from time to time may voluntarily prepay the Loans in whole or in part; provided, however, that (i) any prepayment of the Revolving Facility shall be applied against outstanding Revolving Loans of the Lenders participating in such facility pro rata according to each Lender’s Percentage of the Revolving Facility, (ii) each prepayment of the Loans shall be made to the Administrative Agent not later than 1:00 p.m. on a Business Day, and funds received after that hour shall be deemed to have been received by the Administrative Agent on the next following Business Day, (iii) each partial prepayment of LIBOR Loans shall be accompanied by accrued interest on such partial prepayment through the date of prepayment and additional compensation, if any, calculated in accordance with Section 2.19, (iv) each partial prepayment of LIBOR Loans shall be in an aggregate amount equal to $5,000,000 or more and, after application of any such prepayment, shall not result in a LIBOR Loan remaining outstanding in an amount less than $5,000,000, and (v) each partial prepayment of ABR Loans shall be in an aggregate amount equal to $1,000,000 or a higher integral multiple of $500,000, unless (in either case) the aggregate outstanding balance of all Loans under the Facility being prepaid is less than such minimum Loan amount, in which event any such prepayment may be in such lesser amount. Unless otherwise provided in this Agreement or the other Loan Documents, prepayments from the Borrower of principal within any Facility above shall be applied first to the principal of ABR Loans and then to the principal of LIBOR Loans (and, among such LIBOR Loans, first to those with the earliest expiring Interest Periods).

The Borrower, from time to time upon not less than 5 Business Days’ prior written notice to the Administrative Agent, may permanently reduce the Aggregate Revolving Commitment Amount; provided, however, that no such reduction shall reduce the Aggregate Revolving Commitment Amount to an amount less than the Aggregate Revolving Facility Outstanding Amount. Any such voluntary reduction shall be pro rata as to all Revolving Commitments according to each Revolving Lender’s Revolving Percentage and shall be in an aggregate amount equal to $5,000,000 or a higher integral multiple of $1,000,000. Each such reduction in the Aggregate Revolving Commitment Amount shall constitute a corresponding reduction in the Maximum Aggregate Revolving Facility Amount. The Borrower at any time prior to the Revolving Commitment Termination Date may terminate the Revolving Commitments by (i) providing to the Administrative Agent not less than 5 Business Days’ prior written notice of its intention to so terminate the Revolving Commitments and (ii) making payment in full of all Revolving Loans and all other monetary Obligations. A notice of termination of the Revolving Commitments delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, and such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied; provided, however, that the Borrower shall be responsible for all reasonable out-of-pocket costs and expenses of the Administrative Agent and the Lenders caused by the revocation of such notice of termination in accordance with Sections 2.19 and 9.4.

(a)    Request to Increase. Following the date hereof, and provided no Event of Default has occurred and is continuing, the Borrower may, with the consent of and in coordination with the Administrative Agent and each Lender increasing its Revolving Commitment (including any Eligible Assignee that has not been a Lender but becomes a Lender in connection therewith) as to all of the matters set forth below in this Section 2.14, from time to time propose to increase the Aggregate Revolving Commitment Amount by increasing the Revolving Commitments of one or more Lenders or by obtaining a Revolving Commitment from an Eligible Assignee that will become a Lender. The aggregate principal amount of each increase to the Aggregate Revolving Commitment Amount made pursuant to this Section 2.14 (the amount of any such increase, the “Increased Commitment Amount”) shall be equal to an integral multiple of $5,000,000. No such increase shall cause the Aggregate Revolving Commitment Amount to exceed the Maximum Aggregate Revolving Facility Amount. No more than two increases in the Aggregate Revolving Commitment Amount may be effected pursuant to this Section 2.14. No Lender shall be obligated to increase its Revolving Commitment as a result of any such request by the Borrower, but no Lender (other than the Administrative Agent, in that capacity) shall have any right to object to the allocation of any Increased Commitment Amount among the other Lenders (including any Person who will become a Lender in connection therewith).

(b)    Conditions Precedent. Any increase in the Aggregate Revolving Commitment Amount under this Section 2.14 shall become effective upon the receipt by the Administrative Agent of:

Agreement and to be bound by all the terms and provisions hereof. Any such amendment, modification or joinder may provide that interest or Facility Fees with respect to any Increased Commitment Amount will accrue at the rates set forth herein or at a higher rate.

(c)    Adjustments. On the effective date of any Increased Commitment Amount, the Borrower shall, in coordination with the Administrative Agent, repay the outstanding Advances of certain Lenders, and incur additional Advances from certain other Lenders, in each case to the extent necessary so that all of the Lenders participate in each outstanding Loan ratably on the basis of their respective Revolving Commitments (after giving effect to any increase in the Aggregate Revolving Commitment Amount pursuant to this Section 2.14). The Borrower shall be obligated to pay to the applicable Lenders any costs of the type referred to in Section 2.19 in connection with any such repayment.

(d)    Conflicts with Other Provisions. This Section 2.14 shall supersede any provisions in Section 9.2 to the contrary.

(a)    Making of Payments. All payments of principal of and interest due hereunder shall be made to the Administrative Agent for the account of the applicable Lenders pro rata according to their respective Percentages of the applicable Facility. All payments of fees pursuant to Section 2.10 shall be made to the Administrative Agent for the account of the Administrative Agent or the Lenders, as specified in Section 2.10. All payments hereunder shall be made to the Administrative Agent at its office in Charlotte, North Carolina (or such other office as the Administrative Agent may designate) not later than 2:00 p.m. on the date due, in immediately available funds, without setoff or counterclaim, and funds received after that hour shall be deemed to have been received on the next following Business Day. The Borrower hereby authorizes the Administrative Agent to charge the Borrower’s demand deposit account maintained with the Administrative Agent (or with any other Lender) for the amount of any Obligation on its due date, but the Administrative Agent’s failure to so charge any such account shall in no way affect the obligation of the Borrower to make any such payment. The Administrative Agent shall remit to each Lender in immediately available funds on the same Business Day as received by the Administrative Agent its share of all such payments received by

the Administrative Agent for the account of such Lender. All payments under Sections 2.16, 2.17 or 2.19 shall be made by the Borrower directly to the Lender entitled thereto.

(b)    Effect of Payments. Each payment by the Borrower to the Administrative Agent for the account of any Lender pursuant to this Agreement shall be deemed to constitute payment by the Borrower directly to such Lender, provided, however, that in the event any such payment by the Borrower to the Administrative Agent is required to be returned to the Borrower for any reason whatsoever, then the Borrower’s obligation to such Lender with respect to such payment shall be deemed to be automatically reinstated.

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

(d)    Due Date Extension. Subject to subsection (b) of the definition of “Interest Period” with respect to LIBOR Loans, if any payment of principal of or interest on any Loan or any fees payable hereunder falls due on a day which is not a Business Day, then such due date shall be extended to the next following Business Day, and (in the case of principal) additional interest shall accrue and be payable for the period of such extension.

(e)    Application of Payments. Except as otherwise provided herein (including as set forth in Section 7.4), (i) so long as no Default or Event of Default has occurred and is continuing hereunder, each payment received from the Borrower shall be applied to such Obligations as the Borrower shall specify by notice to be received by the Administrative Agent on or before the date of such payment; and (ii) in the absence of such notice and in any event during the continuance of any Default or Event of Default, payments received from the Borrower shall be applied, first, to payment of that portion of the Obligations then due and owing constituting fees, indemnities, expenses and other amounts, including attorney fees, payable to the Administrative Agent in its capacity as such; second, to pay fees then due and owing under Section 2.10; third, to pay interest then due and owing with respect to the Loans; fourth, to pay principal of the Revolving Loans; and fifth, to the payment of any other Obligations in such order as the Administrative Agent shall determine in its discretion.

(a)    Increased Costs Generally. If any Change in Law shall:

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any LIBOR Loan (or of maintaining its obligation to make any such Loan), or to reduce the amount of any sum received or receivable by such Lender hereunder (whether of principal, interest or any other amount) then, upon request of such Lender, the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered.

(b)    Capital Requirements. If any Lender determines that any Change in Law affecting such Lender or any lending office of such Lender or such Lender’s holding company, if any, regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made such Lender, to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered.

(c)    Certificates for Reimbursement. A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section and delivered to the Borrower shall be conclusive absent demonstrable error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 Business Days after receipt thereof.

(d)    Delay in Requests. Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s right to demand such compensation, provided that the Borrower shall not be required to compensate a Lender pursuant to this Section for any increased costs incurred or reductions suffered more than three months prior to the date that such Lender notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the three-month period referred to above shall be extended to include the period of retroactive effect thereof).

(a)    Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower hereunder or under any other Loan Document shall be made free and

clear of and without reduction or withholding for any Indemnified Taxes or Other Taxes, provided that if the Borrower shall be required by applicable law to deduct any Indemnified Taxes (including any Other Taxes) from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Lender Party entitled thereto receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions, and (iii) the Borrower shall timely pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b)    Payment of Other Taxes by the Borrower. Without limiting the provisions of paragraph (a) above, the Borrower shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c)    Indemnification by the Borrower. The Borrower shall indemnify each Lender Party within 10 Business Days after demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by such Lender Party, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender Party (with a copy to the Administrative Agent) shall be conclusive absent manifest error.

(d)    Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e)    Status of Lenders. Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is resident for tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments hereunder or under any other Loan Document shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements.

(f)    Treatment of Certain Refunds. If any Lender Party determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section, it shall pay to the Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of such Lender Party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund), provided that the Borrower, upon the request of a Lender Party will repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to such Lender Party

in the event such Lender Party is required to repay such refund to such Governmental Authority. This paragraph shall not be construed to require any Lender Party to make available its tax returns (or any other information relating to its taxes that it deems confidential) to the Borrower or any other Person.

If at any time:

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

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

(c)    any Lender determines that the Adjusted LIBO Rate as determined by the Administrative Agent will not adequately and fairly reflect the cost to that Lender of maintaining or funding its Loans, or that the making or funding of Loans based on the Adjusted LIBO Rate has become impracticable as a result of an event occurring after the date of this Agreement that in the opinion of that Lender materially affects such Loans; or

(d)    any Change in Law or any change in the interpretation of applicable laws or regulations by any governmental authority, central bank, comparable agency or any other regulatory body charged with the interpretation, implementation or administration thereof, or compliance by a Lender with any request or directive (whether or not having the force of law) of any such authority, central bank, comparable agency or other regulatory body, should make it or, in the good faith judgment of the affected Lender, shall raise a substantial question as to whether it is unlawful for such Lender to make, maintain or fund LIBOR Loans,

then (i) the affected Lender shall promptly notify the Borrower and the Administrative Agent, (ii) the obligation of the affected Lender to make or continue any LIBOR Loan, or to convert any Loan into a LIBOR Loan shall, upon the effectiveness of such event, be suspended for the duration of such condition, (iii) for the duration of such condition, any notice by the Borrower pursuant to Section 2.1, 2.2 or 2.3 requesting the affected Lender to make any LIBOR Loan, to continue any LIBOR Loan or to convert any Revolving ABR Loan into a LIBOR Loan shall be construed as a request to make (or continue) such Loan as an ABR Loan, and (iv) at the option of such Lender, the Adjusted Base Rate shall be determined without reference to the Floating LIBO Rate.

The Borrower hereby agrees that upon demand by any Lender (which demand shall be accompanied by a written statement setting forth the basis for the calculations of the amount being claimed) the Borrower will indemnify such Lender against any loss or expense which such Lender may have sustained or incurred (including any net loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund or maintain LIBOR Loans) or which such Lender may be deemed to have sustained or incurred, as reasonably determined by such Lender, (i) as a consequence of any failure by the Borrower to make any payment when due of any amount due hereunder in connection with any LIBOR Loans, (ii) due to any failure of the Borrower to borrow or convert any LIBOR Loans on a date specified therefor in a notice thereof or (iii) due to any payment or prepayment of any LIBOR Loan on a date other than the last day of the applicable Interest Period for such LIBOR Loan. For this purpose, all notices under Sections 2.1, 2.2 and 2.3 shall be deemed to be irrevocable.

Each Lender, if it so elects, may fulfill its agreements hereunder with respect to any LIBOR Loan by causing a foreign branch or affiliate of such Lender to make such LIBOR Loan; provided, that in such event the obligation of the Borrower to repay such LIBOR Loan shall nevertheless be to such Lender and such LIBOR Loan shall be deemed held by such Lender for the account of such branch or affiliate.

Notwithstanding any provision of this Agreement to the contrary, each Lender shall be entitled to fund and maintain all or any part of its LIBOR Loans in any manner it deems fit, it being understood, however, that for the purposes of this Agreement (including Section 2.19 hereof) all determinations hereunder shall be made as if each Lender had actually funded and maintained each LIBOR Loan during each Interest Period for such LIBOR Loan through the purchase of deposits having a maturity corresponding to such Interest Period and bearing an interest rate equal to the appropriate Adjusted LIBO Rate for such Interest Period.

Determinations and statements of a Lender pursuant to Section 2.16, 2.17, 2.18 or 2.19 shall be conclusive absent demonstrable error. Each Lender may use reasonable averaging and attribution methods in determining compensation pursuant to such Sections 2.16, 2.17 and 2.19 and the provisions of Sections 2.16, 2.17 and 2.19 shall survive termination of this Agreement.

The obligations of each Lender Party hereunder are the several obligations of such Lender Party, and no Lender Party shall be responsible for the obligations of any other Lender Party hereunder, nor will the failure by any Lender Party to perform any of its obligations hereunder relieve any other Lender Party from the performance of its obligations hereunder. Nothing contained in this Agreement, and no action taken by any Lender Party pursuant hereto or in connection herewith or pursuant to or in connection with the Loan Documents shall be deemed to constitute the Lender Parties as a partnership, association, joint venture, or other entity.

(a)    Defaulting Lender Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by applicable law:

of Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; third, if so determined by the Administrative Agent and the Borrower, to be held in a deposit account and released pro rata in order to satisfy such Defaulting Lender’s potential future funding obligations with respect to Loans under this Agreement; fourth, to the payment of any amounts owing to the Lenders as a result of any judgment of a court of competent jurisdiction obtained by any Lender against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; fifth, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender's breach of its obligations under this Agreement; and sixth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Loans were made at a time when the conditions set forth in Section 3.2 were satisfied or waived, such payment shall be applied solely to pay the Loans of all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of such Defaulting Lender until such time as all Loans are held by the Lenders pro rata in accordance with the Commitments under the applicable Facility. Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender pursuant to this Section 2.24(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(b)    Defaulting Lender Cure. If the Borrower and the Administrative Agent agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein, that Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans to be held pro rata by the Lenders in accordance with the Commitments under the applicable Facility, whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

The obligation of the Lenders to effect any Borrowing is subject to the condition precedent that each Lender shall have received on or before the day of the first Borrowing all of the following, each dated (unless otherwise indicated) as of the date hereof, in form and substance satisfactory to each Lender:

(a)    The Notes, properly executed on behalf of the Borrower.

(b)    A certificate of the secretary of the Borrower (i) certifying that the execution, delivery and performance of the Loan Documents and other documents contemplated hereunder to which such corporation is a party have been duly approved by all necessary action of the Board of Directors of the Borrower, and attaching true and correct copies of the applicable resolutions granting such approval, (ii) certifying that attached to such certificate are true and correct copies of the articles of incorporation and bylaws of the Borrower and all Authorizing Orders, together with such copies, and (iii) certifying the names of the officers of the Borrower that are authorized to sign the Loan Documents and other documents contemplated hereunder, including requests for Borrowings, together with the true signatures of such officers. The Lenders may conclusively rely on such certificate until they shall receive a further certificate of the Secretary or Assistant Secretary of the Borrower canceling or amending the prior certificate and submitting the signatures of the officers named in such further certificate.

(c)    Certificates of good standing of the Borrower, dated not more than ten days before such date.

(d)    A signed copies of an opinion of Paul K. Sandness, general counsel for the Borrower, substantially in the form of Exhibit E-1, and the opinion of Cohen Tauber Spievack & Wagner P.C., special counsel to the Borrower, substantially in the form of Exhibit E-2, each addressed to the Lenders.

(e)    All fees required to be paid as of the date hereof pursuant to this Agreement or any Fee Letter.

The obligation of the Lenders to effect any Borrowing shall be subject to the further conditions precedent that on the date of such Borrowing:

(a)    the representations and warranties contained in Article IV (other than Section 4.6) are correct on and as of the date of such Borrowing as though made on and as of such date, except to the extent that such representations and warranties relate solely to an earlier date;

(b)    the Borrower has delivered to the Administrative Agent an opinion in the form of Exhibit F hereto, duly executed by the general counsel or associate general counsel of the Borrower; and

(c)    no event has occurred and is continuing, or would result from such Borrowing, which constitutes a Default or an Event of Default.

The Borrower represents and warrants to the Lenders as follows:

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

The execution, delivery and performance by the Borrower of the Loan Documents, and the borrowings from time to time hereunder, have been duly authorized by all necessary corporate action and by all necessary public utilities commissions and any other regulatory bodies having jurisdiction over the Borrower (except as noted in Schedule 4.2 to the Agreement with respect to Borrowings made after December 31, 2011), and do not and will not (i) require any consent or approval of the stockholders of the Borrower, or any authorization, consent or approval by any governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign, other than Authorizing Orders set forth in Schedule 4.2 that (except as noted therein with respect to Borrowings made after December 31, 2011) have been obtained and copies of which have been delivered to the Administrative Agent pursuant to Section 3.1, (ii) violate any provision of any law, rule or regulation (including, without limitation, Regulation T, U or X of the Board of Governors of the Federal Reserve System) or of any order, writ, injunction or decree presently in effect having applicability to the Borrower or of the articles of incorporation or bylaws of the Borrower, (iii) result in a breach of or constitute a default under any indenture or loan or credit agreement or any other agreement, lease or instrument to which the Borrower is a party or by which it or its properties may be bound or affected, or (iv) result in, or require, the creation or imposition of any Lien or other charge or encumbrance of any nature (other than those in favor of the Administrative Agent to secure one or more of the Obligations) upon or with respect to any of the properties now owned or hereafter acquired by the Borrower.

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

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

The Borrower has furnished to the Lenders its audited consolidated financial statement as of December 31, 2010, and its unaudited interim financial statement as of March 31, 2011. Those financial statements fairly present the financial condition of the Borrower and its Subsidiaries on the dates thereof and the results of their operations and cash flows for the periods then ended, and were prepared in accordance with GAAP, except as expressly noted therein.

There has been no material adverse change in the business, properties or condition (financial or otherwise) of the Borrower since December 31, 2010.

Except as set forth in the Borrower’s Annual Report on Form 10-K for the year ended December 31, 2010, or in any document subsequently filed pursuant to Section 13, 14 or 15(d) of the Exchange Act, there are no actions, suits or proceedings pending or, to the knowledge of the Borrower, threatened against or affecting the Borrower or the properties of the Borrower, before any court or governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign, which, if determined adversely to the Borrower, would have a Material Adverse Effect.

The Borrower conducts in the ordinary course of business a review of the effect of existing Environmental Laws and existing Environmental Claims on its business, operations and properties and, as a result thereof, the Borrower has reasonably concluded that such Environmental Laws and Environmental Claims could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, exclusive of Environmental Claims as set forth in the Borrower’s Annual Report on Form 10-K for the year ended December 31, 2010, or in any document subsequently filed pursuant to Section 13, 14 or 15(d) of the Exchange Act.

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). No part of the proceeds of any Credit Extension will be used directly or indirectly for any purpose that violates, or that would require any Lender to make any filings in accordance with, the provisions of Regulation T, U or X of the Board of Governors of the Federal Reserve System as now and from time to time hereafter in effect.

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

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

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

Each of the Borrower and its ERISA Affiliates is in compliance in all material respects with the applicable provisions of ERISA and the Code and published interpretations thereunder, except for any such failure that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. No ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other such ERISA Events for which liability is reasonably expected to occur, could reasonably be expected to result in a Material Adverse Effect.

So long as any Note shall remain unpaid or the Facility shall be outstanding, the Borrower will comply with the following requirements, unless the Required Lenders shall otherwise consent in writing:

The Borrower will deliver to each Lender:

(a)    As soon as available, and in any event within 90 days after the end of each fiscal year of the Borrower, a copy of the annual audit report of the Borrower and its Subsidiaries prepared on a consolidated basis with an unqualified opinion of independent certified public accountants selected by the Borrower and acceptable to the Required Lenders, which annual report shall include the consolidated balance sheets of the Borrower and its Subsidiaries as of the end of such fiscal year and the related consolidated statements of income, common stockholders’ equity and cash flows of the Borrower and its Subsidiaries for the fiscal year then ended, all in reasonable detail and all prepared in accordance with GAAP.

(b)    As soon as available, and in any event within 120 days after the end of each fiscal year of the Borrower:

(c)    As soon as available and in any event within 45 days after the end of each fiscal quarter of the Borrower, a copy of (A) the unaudited consolidated balance sheets of the Borrower and its Subsidiaries as of the end of such quarter, (B) the related unaudited consolidated statements of income for such quarter, and (C) the related unaudited consolidated statements of income and cash flows of the Borrower and its Subsidiaries for the year to date, all in reasonable detail and prepared in accordance with GAAP, subject to year‑end audit adjustments.

(d)    As soon as available and in any event within 60 days after the end of each fiscal quarter of the Borrower, a copy of (A) the unaudited nonconsolidated balance sheets of the Borrower at the end of such quarter, (B) the related unaudited nonconsolidated statements of income for such quarter, and (C) the related unaudited nonconsolidated statements of income, retained earnings and cash flows of the Borrower for the year to date, all in reasonable detail and prepared in accordance with GAAP, subject to year-end adjustments.

(e)    Concurrently with the delivery of any financial statements under paragraph (a), (b), (c) or (d), a Compliance Certificate, duly executed by the chief financial officer of the Borrower.

(i)    Promptly upon becoming available, copies of any reports or applications filed by the Borrower with any governmental body if such reports indicate any material change in the business, operations, affairs or condition of the Borrower, or if copies thereof are requested by any Lender.

(j)    Immediately after the commencement thereof, notice in writing of all litigation and of all proceedings before any governmental or regulatory agency affecting the Borrower of

the type described in Section 4.7 or which seek a monetary recovery against the Borrower in excess of $10,000,000.

(k)    As promptly as practicable (but in any event not later than 5 Business Days) after an officer of the Borrower obtains knowledge of the occurrence of any Default or Event of Default, notice of such occurrence, together with a detailed statement by a responsible officer of the Borrower of the steps being taken by the Borrower to cure the effect of such event.

(l)    Promptly upon becoming aware of an ERISA Event, a written notice specifying the nature thereof, what action the Borrower has taken, is taking or proposes to take with respect thereto, and, when known, any action taken or threatened by the Internal Revenue Service, the PBGC or the Department of Labor with respect thereto.

(m)    Promptly upon (i) the adoption of any Pension Plan, or (ii) the adoption of any amendment to a Pension Plan, if such amendment results in a material increase in contributions or Unfunded Pension Liability, written notice specifying the nature thereof.

(n)    Upon request of any Lender, copies of the most recent annual report (Form 5500 Series), including any supporting schedules, filed by the Borrower or any ERISA Affiliate with the Internal Revenue Service with respect to any Plan.

(o)    Such information (in addition to that specified elsewhere in this Section) respecting the financial condition and results of operations of the Borrower as any Lender may from time to time reasonably request.

The Borrower will keep accurate books of record and account for itself in which true and complete entries will be made in accordance with GAAP and, upon request of any Lender, will give any representative of that Lender access to, and permit such representative to examine, copy or make extracts from, any and all books, records and documents in its possession, to inspect any of its properties and to discuss its affairs, finances and accounts with any of its principal officers, all at such times during normal business hours and as often as any Lender may reasonably request.

The Borrower will comply with the requirements of applicable laws and regulations, except any law and regulation (i) the compliance with which is contested in good faith or the subject of a bona fide dispute, and (ii) the noncompliance with which would not have a Material Adverse Effect. In addition, and without limiting the foregoing sentence, the Borrower shall (i) ensure, and cause each Subsidiary to ensure, that no Person who owns a controlling interest in or otherwise controls the Borrower or any Subsidiary is or shall be listed on the Specially Designated Nationals and Blocked Person List or other similar lists maintained by the Office of Foreign Assets Control (“OFAC”), the Department of the Treasury or included in any Executive Orders, (ii) not use or permit the use of any Credit Extension to violate any of the foreign asset control regulations of OFAC or any enabling statute or Executive Order relating thereto, and (iii) comply, and cause each Subsidiary to comply, with all applicable Bank Secrecy Act laws and regulations, as amended, and with the Uniting And Strengthening America By Providing Appropriate Tools Required To Intercept And Obstruct Terrorism Act (USA Patriot Act of 2001).

The Borrower will pay or discharge, when due, (a) all taxes, assessments and governmental charges levied or imposed upon it or upon its income or profits, or upon any properties belonging to it, prior to the

date on which penalties attach thereto, (b) all federal, state and local taxes required to be withheld by it, and (c) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a Lien or charge upon any properties of the Borrower; provided, that the Borrower shall not be required to pay any such tax, assessment, charge or claim so long as (x) the amount, applicability or validity of such tax, assessment, charge or claim is being contested in good faith by appropriate proceedings or is the subject of a bona fide dispute, and (y) the Borrower has provided adequate reserves therefor in accordance with GAAP, except (with respect to any of the foregoing) to the extent that the failure to do so could not reasonably be expected to have a Material Adverse Effect.

Subject to transactions permitted by Sections 6.4, the Borrower shall maintain and preserve all its property which is used or useful in its business in good working order and condition, ordinary wear and tear excepted, except to the extent that noncompliance would not have a Material Adverse Effect.

The Borrower shall maintain with financially sound and reputable independent insurers, insurance with respect to its properties and business against loss or damage of the kinds customarily insured against by Persons engaged in the same or similar business, of such types and in such amounts (including deductibles, co-insurance and self-insurance, if adequate reserves are maintained with respect thereto) as are customarily carried under similar circumstances by such other Persons, except to the extent that noncompliance would not have a Material Adverse Effect, and the Borrower will furnish any Lender upon request full information as to the insurance carried within 15 Business Days.

Subject to transactions permitted by Section 6.4, the Borrower shall (iv) preserve and maintain in full force and effect its corporate existence and good standing under the laws of its state or jurisdiction of incorporation; (v) preserve and maintain in full force and effect all governmental rights, privileges, qualifications, permits, licenses and franchises necessary or desirable in the normal conduct of its business; and (vi) preserve its business organization and goodwill; and (vii) preserve or renew all of its registered patents, trademarks, trade names and service marks; except, in each case, to the extent that failure to do so does not have a Material Adverse Effect.

So long as any Note shall remain unpaid or the Facility shall be outstanding, the Borrower agrees that, without the prior written consent of the Required Lenders:

The Borrower will not create, incur or suffer to exist any Lien in, of or on the property of the Borrower, except:

(a)    Liens for taxes, assessments of governmental charges or levies on its property if the same shall not at the time be delinquent or thereafter can be paid without penalty, or are being contested in good faith and by appropriate proceedings.

(b)    Liens imposed by law, such as carriers’, warehousemen’s and mechanics’ liens and other similar liens arising in the ordinary course of business which secure payment of

obligations not yet due and payable or remaining payable without penalty or which are being contested in good faith by appropriate proceedings.

(c)    Liens arising out of pledges or deposits under worker’s compensation laws, unemployment insurance, old age pensions, or other social security or retirement benefits, or similar legislation.

(d)    Utility easements, buildings restrictions and such other encumbrances or charges against real property as are of a nature generally existing with respect to properties of a similar character and which do not in any material way affect the marketability of the same or interference with the use thereof in the business of the Borrower.

(e)    Purchase money Liens upon or in any property acquired or held by the Borrower in the ordinary course of business, provided that (i) no such Lien is created later than the 90th day following the acquisition or completion of construction of such property by the Borrower, and (ii) no such Lien extends or shall extend to or cover any property of the Borrower other than the property then being acquired, fixed improvements then or thereafter erected thereon and improvements and modifications thereto necessary to maintain such properties in working order.

(f)    Liens incurred or deposits made in the ordinary course of business to secure (or to obtain letters of credit that secure) the performance of tenders, statutory obligations, surety bonds, appeal bonds, bids, leases (other than Capitalized Leases), performance bonds, purchase, construction or sales contracts and other similar obligations, in each case not incurred or made in connection with the incurrence of any Obligation.

(g)    Liens resulting from judgments, unless such judgments are not bonded or otherwise discharged within 60 days; are not stayed pending appeal or otherwise being appropriately contested in good faith; or are not discharged within 45 days after expiration of any such stay.

(h)    Liens created under or in connection with the Indenture as such Indenture exists on the date hereof, without regard to any waiver, amendment, modification or restatement thereof.

(i)    Liens permitted under the Indenture as such Indenture exists on the date hereof, without regard to any waiver, amendment, modification or restatement thereof.

(j)    Liens on any property of the Borrower (other than those described in subsection (e)) securing any indebtedness for borrowed money in existence on the date hereof and listed in Schedule 6.1 hereto.

(l)    Any governmental authority or other administrative or legal authority having regulatory jurisdiction over the Borrower takes any action which has a Material Adverse Effect on the Borrower.

Upon the occurrence of an Event of Default or at any time thereafter until such Event of Default is cured to the written satisfaction of the Required Lenders, the Administrative Agent may, with the consent of the Required Lenders, and shall, at the request of the Required Lenders, exercise any or all of the following rights and remedies:

(a)    The Administrative Agent may, by notice to the Borrower, declare the Facility to be terminated, whereupon the same shall forthwith terminate.

(b)    The Administrative Agent may, by notice to the Borrower, declare the entire unpaid principal amount of the Notes then outstanding, all interest accrued and unpaid thereon, and all other amounts payable under this Agreement to be forthwith due and payable, whereupon the Notes, all such accrued interest and all such amounts shall become and be forthwith due and payable, without presentment, demand, protest or further notice of any kind, all of which are hereby expressly waived by the Borrower.

(c)    The Lenders may exercise any other rights and remedies available to them by law or agreement.

Notwithstanding the foregoing, upon the occurrence of an Event of Default described in Section 7.1(g) or 7.1(h) hereof, the entire unpaid principal amount of the Notes then outstanding, all interest accrued and unpaid thereon, and all other amounts payable under this Agreement shall be immediately due and payable without presentment, demand, protest or notice of any kind.

If an Event of Default shall have occurred and shall be continuing, each Lender Party and each of their Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Lender Party or any such Affiliate to or for the credit or the account of the Borrower against any and all of the obligations of the Borrower now or hereafter existing under this Agreement or any other Loan Document to such Lender Party or any such Affiliate, irrespective of whether or not such Lender Party shall have made any demand under this Agreement or any other Loan Document and although such obligations of the Borrower may be contingent or unmatured or are owed to a branch or office of such Lender Party different from the branch or office holding such deposit or obligated on such indebtedness. The rights of each Lender Party and its Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender Party or its Affiliates may have.

If all or any portion of the Obligations have been accelerated or the Administrative Agent has exercised any remedy set forth in this Agreement or any other Loan Document, all payments received by the Lenders upon the Obligations and all net proceeds from the enforcement of the Obligations shall be applied in the following order:

(a)    first, to payment of that portion of the Obligations constituting fees, indemnities, expenses and other amounts, including attorney fees, payable to the Administrative Agent in its capacity as such;

(b)    second, to payment of that portion of the Obligations constituting fees, indemnities and other amounts (other than principal and interest) payable to the Lenders under the Loan Documents, including attorney fees (ratably among the Lenders in proportion to the respective amounts described in this clause payable to them);

(c)    third, to payment of that portion of the Obligations constituting accrued and unpaid interest on the Loans (ratably among the Lender Parties in proportion to the respective amounts described in this clause payable to them);

(d)    fourth, to payment of that portion of the Obligations constituting unpaid principal of the Advances and Hedging Obligations owed to a Lender Hedge Counterparty (ratably among the Lender Parties and Lender Hedge Counterparties in proportion to the respective amounts described in this clause held by them);

(e)    fifth, to the remaining Obligations (ratably among the Lender Parties in proportion to the respective amounts described in this clause held by them); and

(f)    last, the balance, if any, after all of the Obligations have been indefeasibly paid in full, to the Borrower or as otherwise required by applicable law.

Each of the Lenders hereby irrevocably appoints Wells Fargo to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of the Administrative Agent and the Lenders, and the Borrower shall have no rights (as a third party beneficiary or otherwise) of any of such provisions. The use of the term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties.

The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent. The term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

(a)    The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Administrative Agent:

(b)    The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 9.2 and 7.2) or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and nonappealable judgment. The Administrative Agent shall be deemed not to have knowledge of any Default or Event of Default unless and until notice describing such Default or Event of Default is given to the Administrative Agent by the Borrower or a Lender.

(c)    The Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default or Event of Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article III or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan that by its terms must be fulfilled to the satisfaction of a Lender, the Administrative Agent may presume that such condition is satisfactory to such Lender unless the Administrative Agent shall have received notice to the contrary from such Lender prior to the making of such Loan. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub‑agents appointed by the Administrative Agent. The Administrative Agent and any such sub‑agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub‑agent and to the Related Parties of the Administrative Agent and any such sub‑agent, and shall apply to their activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and non appealable judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub‑agents.

(a)    The Administrative Agent may at any time give notice of its resignation to the Lenders and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of any such bank with an office in the United States. If no such successor has been so appointed by the Required Lenders and has accepted such appointment within 45 days after the retiring Administrative Agent gives notice of its resignation (or such earlier day as shall be agreed by the Required Lenders) (the “Resignation Effective Date”), then the retiring Administrative Agent may (but shall not be obligated to) on behalf of the Lenders appoint a successor Administrative Agent meeting the qualifications set forth above. Whether or not a successor has been appointed, such resignation shall become effective in accordance with such notice on the Resignation Effective Date.

(b)    If the Person serving as Administrative Agent is a Defaulting Lender pursuant to clause (d) of the definition thereof, the Required Lenders may, to the extent permitted by applicable law, by notice in writing to the Borrower and such Person remove such Person as Administrative Agent and, in consultation with the Borrower, appoint a successor. If no such successor has been so appointed by the Required Lenders and has accepted such appointment within 30 days (or such earlier day as shall be agreed by the Required Lenders) (the “Removal Effective Date”), then such removal shall nonetheless become effective in accordance with such notice on the Removal Effective Date.

(c)    With effect from the Resignation Effective Date or the Removal Effective Date (as applicable), (1) the retiring or removed Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Administrative Agent on behalf of the Lenders under any of the Loan Documents, the retiring or removed Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed), and (2) all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender directly, until such time as the Required Lenders appoint a successor Administrative Agent as provided for above. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring or removed Administrative Agent, and the retiring or removed Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring or removed Administrative Agent’s resignation or removal hereunder and under the other Loan Documents, the provisions of this Article and Section 9.4 shall continue in effect for the benefit of such retiring or removed Administrative Agent, its sub‑agents and their Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring or removed Administrative Agent was acting as Administrative Agent.

Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

Anything herein to the contrary notwithstanding, none of the Persons listed on the cover page hereof as “joint lead arranger,” “syndication agent” or “joint lead bookrunner” shall have any powers, duties, obligations or responsibilities under this Agreement or any of the other Loan Documents, except in any capacity, as applicable, as the Administrative Agent or a Lender.

In case of the pendency of any proceeding under any Debtor Relief Law or any other judicial proceeding relative to the Borrower, the Administrative Agent (irrespective of whether the principal of any Obligation is then due and payable and irrespective of whether the Administrative Agent has made any demand on the Borrower) shall be entitled and empowered (but not obligated), by intervention in such proceeding or otherwise:

(a)    to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lender Parties (including any claim for the reasonable compensation, expenses, disbursements and advances of

the Lender Parties and their respective agents and counsel and all other amounts due the Lender Parties under Sections 2.10 and 9.4) allowed in such judicial proceeding; and

(b)    to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender Party to make such payments to the Administrative Agent and, in the event that the Administrative Agent consents to the making of such payments directly to the Lender Parties, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Sections 2.10 and 9.4.

(a)    Each Lender Party hereby irrevocably authorizes the Administrative Agent to act as collateral agent of and for such Lender Party for purposes of holding, perfecting and disposing of collateral under the Loan Documents and appoints the Administrative Agent as nominal beneficiary or nominal secured party, as the case may be, under the Loan Documents and all related UCC financing statements. Without limiting the foregoing, the Lenders irrevocably authorize the Administrative Agent, at its option and in its discretion,

Upon request by the Administrative Agent at any time, the Required Lenders will confirm in writing the Administrative Agent’s authority to release or subordinate its interest in particular types or items of property, or to release any guarantor from its obligations pursuant to this Section 8.10.

(b)    The Administrative Agent shall not be responsible for or have a duty to ascertain or inquire into any representation or warranty regarding the existence, value or collectability of any collateral, the existence, priority or perfection of the Administrative Agent’s Lien thereon, or any certificate prepared by the Borrower in connection therewith, nor shall the Administrative Agent be responsible or liable to any Lender Party for any failure to monitor or maintain any portion of the collateral.

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

No amendment or waiver of any provision of any Loan Document or consent to any departure by the Borrower therefrom shall be effective unless the same shall be in writing and signed by the Required Lenders (or by the Administrative Agent with the consent or at the request of the Required Lenders), and, if the rights or duties of the Administrative Agent are affected thereby, by the Administrative Agent. Notwithstanding the foregoing, no amendment, modification, termination, waiver or consent shall do any of the following unless the same shall be in writing and signed by the Administrative Agent and each Lender affected thereby (and, as to clauses (d) and (f) hereof, all Lenders shall be deemed affected): (a) change the amount of any Commitment (except as permitted in accordance with Section 2.13, 2.14 or 9.6(b)), (b) reduce the amount of any principal, interest fees or other amounts payable to a Lender under any Loan Document, (c) postpone any date fixed for, or reduce the amount of, any payment of principal, interest, fees or other amounts payable to a Lender under any Loan Document, (d) change the definition of “Required Lenders,” (e) amend Section 7.4 in a manner that would alter the ratable sharing of payments provided thereby, or (f) amend this Section 9.2 or any other provision of this Agreement requiring the consent or other action of the Required Lenders or any particular Lender. Notwithstanding anything to the contrary herein, no Lender who is at the time a Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or consent hereunder, except that (y) the Commitment of such Lender may not be increased or extended without the consent of such Lender, and (z) without the consent of all Defaulting Lenders, no amendment may be effected that has an adverse impact on the Defaulting Lenders (as a class) that is materially different than the impact of such amendment on the Non-Defaulting Lenders. Any waiver shall be effective only in the specific instance and for the specific purpose for which given. No notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances.

(a)    Use of Platform to Distribute Communications. The Administrative Agent may make any material delivered by the Borrower to the Administrative Agent, as well as any amendments, waivers, consents, and other written information, documents, instruments and other materials relating to the Borrower, or any of its Subsidiaries, or any other materials or matters relating to any Loan Documents, or any of the transactions contemplated hereby or thereby (collectively, the “Communications”) available to the Lender Parties by posting such notices on an electronic delivery system such as IntraLinks or a substantially similar electronic system (the “Platform”). The Platform is provided “as is” and “as available,” and neither the Administrative Agent nor any of its Affiliates warrants the accuracy, completeness, timeliness, sufficiency, or sequencing of the Communications posted on the Platform. The Administrative Agent and its Affiliates expressly disclaim with respect to the Platform any liability for errors in transmission, incorrect or incomplete downloading, delays in posting or delivery, or problems accessing the

Communications posted on the Platform. No warranty of any kind, express, implied or statutory, including any warranty of merchantability, fitness for a particular purpose, non-infringement of third party rights or freedom from viruses or other code defects, is made by the Administrative Agent or any of its Affiliates in connection with the Platform.

(b)    Notice by Electronic Means. Each Lender agrees (i) on or before the date it becomes a party to this Agreement, to notify the Administrative Agent in writing of the e-mail addresses to which a notice under this Agreement (herein, a “Notice”) may be sent to it and from time to time thereafter to ensure that the Administrative Agent has on record an effective e-mail address for it, and (ii) that any Notice may be sent to such e-mail addresses. Each Lender agrees that an e‑mail message notice to it (as provided in the previous sentence) specifying that any Communication has been posted to the Platform shall for purposes of this Agreement constitute effective delivery to such Lender of such information, documents or other materials comprising such Communication.

(c)    Notices By Other Means. Except as otherwise expressly provided herein, all notices, requests, demands and other communications provided for under the Loan Documents shall be in writing (including facsimile transmission or email) and shall be sent to the applicable party at its address, e-mail address or facsimile number set forth on Exhibit A or on any Administrative Questionnaire, or as to each party, at such other address, e-mail address or facsimile number as shall be designated by such party in a written notice to the other party complying as to delivery with the terms of this Section 9.3. All such notices, requests, demands and other communications shall be effective (i) when received, if sent by facsimile, email, hand delivery or overnight courier, or (ii) three Business Days after the date when sent by registered or certified mail, postage prepaid; provided, however, that notices or requests to the Administrative Agent or any Lender pursuant to any of the provisions of Article II shall not be effective until received by the Administrative Agent or such Lender.

(a)    Costs and Expenses. The Borrower shall pay (i) all reasonable out‑of‑pocket expenses incurred by the Administrative Agent and its Affiliates (including the reasonable fees, charges and disbursements of counsel for the Administrative Agent), in connection with the preparation, negotiation, execution, delivery and administration of this Agreement and the other Loan Documents or any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated) and (ii) all out‑of‑pocket expenses incurred by the Administrative Agent or any Lender (including the fees, charges and disbursements of any counsel for the Administrative Agent or any Lender and specifically including allocated costs of in-house counsel if not duplication of the services of outside counsel) in connection with the enforcement or protection of its rights (A) in connection with this Agreement and the other Loan Documents, including its rights under this Section 9.4, or (B) in connection with the Obligations, including all such out‑of‑pocket expenses incurred during any workout, restructuring or negotiations in respect of the Obligations.

(b)    Indemnification by the Borrower. The Borrower shall indemnify each Lender Party and each Affiliate of any Lender Party (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses (including the fees, charges and disbursements of any counsel for any Indemnitee and specifically including allocated costs of in-house counsel if not duplication of the services of outside counsel) incurred by any Indemnitee or asserted against any Indemnitee by any third party or the Borrower arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, any other Loan Document or any agreement or

instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or thereunder or the consummation of the transactions contemplated hereby or thereby, (ii) the Loans or the use or proposed use of the proceeds therefrom, (iii) any actual or alleged presence or release of Hazardous Substances on or from any property owned or operated by the Borrower or its Subsidiaries, or any liability arising from any alleged breach of Environmental Laws related in any way to the Borrower or its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory, whether brought by a third party or by the Borrower, and regardless of whether any Indemnitee is a party thereto, provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the negligence or willful misconduct of such Indemnitee or (y) result from a claim brought by the Borrower against an Indemnitee for breach of such Indemnitee’s obligations hereunder or under any other Loan Document, if the Borrower has obtained a final and nonappealable judgment in its favor on such claim as determined by a court of competent jurisdiction.

(c)    Reimbursement by Lenders. To the extent that the Borrower for any reason fails to indefeasibly pay any amount required under paragraph (a) or (b) of this Section 9.4 to be paid by it to the Administrative Agent (or any sub-agent thereof), or any Affiliate of any of the foregoing, each Lender severally agrees to pay to the Administrative Agent (or any such sub-agent) or such Affiliate, as the case may be, such Lender’s Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount, provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent (or any such sub-agent) in its capacity as such, or against any Affiliate of any of the foregoing acting for the Administrative Agent (or any such sub-agent) in connection with such capacity. The obligations of the Lenders under this paragraph (c) are subject to the provisions of Section 2.23.

(d)    Waiver of Consequential Damages, Etc. To the fullest extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, the Loans or the use of the proceeds thereof. No Indemnitee referred to in paragraph (b) above shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby.

(e)    Payments. All amounts due under this Section 9.4 shall be payable promptly after demand therefor.

(f)    Survival. The agreements in this Section 9.4 shall survive the resignation of the Administrative Agent, the replacement of any Lender, the termination in full of all of the Commitments and the payment, satisfaction or discharge in full of all the other Obligations.

This Agreement and the other Loan Documents may be executed in any number of counterparts, each of which when so executed and delivered shall be deemed to be an original and all of which counterparts of

this Agreement or such other Loan Document, as the case may be, taken together, shall constitute but one and the same instrument.

(a)    Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender, and no Lender may assign or otherwise transfer any of its rights or obligations hereunder, except (i) to an assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of paragraph (d) of this Section or (iii) by way of pledge or assignment of a Lien subject to the restrictions of paragraph (f) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, express or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in paragraph (d) of this Section and, to the extent expressly contemplated hereby, the Affiliates of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b)    Assignments by Lenders. Any Lender may at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitments and the Loans at the time owing to it); provided that any such assignment shall be subject to the following conditions:

withheld or delayed) shall be required unless (x) a Default or Event of Default has occurred and is continuing at the time of such assignment, or (y) such assignment is to a Lender; provided that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within 5 Business Days after having received notice thereof.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the

interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 2.16, 9.4(a) and 9.4(b) with respect to facts and circumstances occurring prior to the effective date of such assignment; provided, that except to the extent otherwise expressly agreed by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section.

(c)    Register. The Borrower hereby designates the Administrative Agent to serve as the Borrower’s agent, solely for purposes of this Section 9.6(c), to maintain a register (the “Register”) on which it will record the Commitments from time to time of each of the Lenders, the Loans made by each of the Lenders and each repayment in respect of the principal amount of the Loans of each Lender. Failure to make any such recordation, or any error in such recordation, shall not affect the Borrower’s obligations in respect of such Loans. With respect to any Lender, the transfer of any Commitment of such Lender and the rights to the principal of, and interest on, any Loan shall not be effective until such transfer is recorded on the Register maintained by the Administrative Agent with respect to ownership of such Commitment and Loans and prior to such recordation all amounts owing to the transferor with respect to such Commitment and Loans shall remain owing to the transferor. The registration of assignment or transfer of all or part of any Commitment or Loan shall be recorded by the Administrative Agent on the Register only upon the acceptance by the Administrative Agent of a properly executed and delivered Assignment and Assumption Agreement pursuant to Section 9.6(b). Coincident with the delivery of such an Assignment and Assumption Agreement to the Administrative Agent for acceptance and registration of assignment or transfer of all or part of a Loan, or as soon thereafter as practicable, the assigning or transferor Lender shall surrender the Note (if any) evidencing such Commitment, and thereupon one or more new Notes in the same aggregate principal amount shall be issued to the assigning or transferor Lender and/or the new Lender at the request of any such Lender. The Borrower agrees to indemnify the Administrative Agent from and against any and all losses, claims, damages and liabilities of whatsoever nature which may be imposed on, asserted against or incurred by the Administrative Agent in performing its duties under this Section 9.6(c).

(d)    Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural person, the Borrower, or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver that would (i) forgive any indebtedness of the Borrower under this Agreement or the Notes, (ii) agree to reduce the rate of interest charged under this Agreement, or (iii) agree to extend the final maturity of any

indebtedness evidenced by the Notes, except as expressly provided by the terms of the Loan Documents, in each case to the extent that such amendment, modification or waiver would affect such Participant. Subject to paragraph (e) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.16 and 2.17 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 7.3 as though it were a Lender, provided such Participant agrees to be subject to Section 9.7 as though it were a Lender.

(e)    Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Sections 2.16 and 2.17 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.17 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.17(e) as though it were a Lender.

(f)    Certain Pledges. Any Lender may at any time pledge or assign a Lien in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or other obligations hereunder resulting in such Lender’s receiving payment of a proportion of the aggregate amount of its Loans and accrued interest thereon or other such obligations greater than its pro rata share thereof as provided herein, then the Lender receiving such greater proportion shall (a) notify the Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans and such other obligations of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and other amounts owing them, provided that:

The Administrative Agent and the Lenders shall keep confidential (and cause their respective officers, directors, employees, agents and representatives to keep confidential) all information, materials and documents furnished by the Borrower, the Administrative Agent or the Lenders (the “Disclosed Information”). Notwithstanding the foregoing, the Administrative Agent and each Lender may disclose Disclosed Information (i) to the Administrative Agent, any other Lender or any Affiliate of any Lender; (ii) to legal counsel, accountants and other professional advisors to the Administrative Agent or such Lender; (iii) to any regulatory body having jurisdiction over any Lender or the Administrative Agent; (iv) to the extent required by applicable laws and regulations or by any subpoena or similar legal process, or requested by any governmental agency or authority; (v) to the extent such Disclosed Information (A) becomes publicly available other than as a result of a breach of this Agreement, (B) becomes available to the Administrative Agent or such Lender on a non-confidential basis from a source other than the Borrower or a Subsidiary, or (C) was available to the Administrative Agent or such Lender on a non-confidential basis prior to its disclosure to the Administrative Agent or such Lender by the Borrower or a Subsidiary; (vi) to the extent the Borrower or such Subsidiary shall have consented to such disclosure in

writing; (vii) to the extent reasonably deemed necessary by the Administrative Agent or any Lender in the enforcement of the remedies of the Administrative Agent and the Lenders provided under the Loan Documents; or (viii) in connection with any potential assignment or participation in the interest granted hereunder, provided that any such potential assignee or participant shall have executed a confidentiality agreement imposing on such potential assignee or participant substantially the same obligations as are imposed on the Administrative Agent and the Lenders under this Section 9.8.

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

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

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

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

If at any time from and after the effective date of this Agreement, the Borrower shall enter into any trust indenture, credit agreement or other agreement for, relating to, or amending any terms or conditions applicable to any unsecured indebtedness in an amount not less than $15,000,000, the Borrower shall promptly so advise the Administrative Agent. Thereupon, if the Required Lenders shall determine that such trust indenture, credit agreement or other agreement includes covenants reasonably determined by the Required Lenders to be more restrictive than those set forth in Articles V and VI, or defaults reasonably determined by the Required Lenders to be less favorable to the Borrower than those set forth

in Article VII, and shall request by notice to the Borrower, the Borrower shall enter into an amendment to this Agreement providing for substantially the same such covenants and defaults as those provided for in such trust indenture, credit agreement or other agreement, to the extent required and as may be selected by the Required Lenders, such amendment to remain in effect for the entire duration of the term to maturity of such indebtedness (to and including the date to which the same may be extended); provided, however, that if any such trust indenture, credit agreement or other agreement shall be modified, supplemented, amended or terminated so as to modify, amend or eliminate such trust indenture or other agreement or any such covenant, term, condition or default so made a part of this Agreement, then, the Borrower shall give the Administrative Agent and the Lenders prompt notice thereof and such modification, supplement or amendment shall operate to modify, amend or eliminate such covenants, term, condition or default as so made a part of this Agreement. Notwithstanding the foregoing, in no event shall this Section 9.14 be construed so as to require the Borrower at any time to grant any Lien in favor of the Administrative Agent or the Lenders hereunder.

Upon execution and delivery of this Agreement by each of the parties hereto and satisfaction of the conditions precedent set forth in Section 3.1, (i) the Existing Credit Facility shall be deemed terminated, and (ii) no Lender (as defined in the Existing Credit Agreement) shall have any further obligation with respect to the Existing Credit Facility. Notwithstanding the foregoing, the Borrower shall continue to have the obligation to pay any principal, interest, fees and other amounts remaining unpaid under the Existing Credit Facility, and the Lenders shall have no obligation to effect any Borrowing hereunder until such amounts have been paid in full or unless such amounts are paid in full by the proceeds of the first Borrowing hereunder.

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

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their respective officers thereunto duly authorized as of the date first above written.

For value received, MDU Resources Group, Inc., a Delaware corporation (the “Borrower”), promises to pay to the order of ________________________________ (the “Lender”), at such place as the Administrative Agent under the Credit Agreement defined below may from time to time designate in writing, in lawful money of the United States of America and in immediately available funds, the principal sum of _____________________________ ($_____________________________), or so much thereof as is advanced by the Lender to the Borrower pursuant to Section 2.1 of the Credit Agreement dated May 26, 2011 among the Borrower, Wells Fargo Bank, National Association, as Administrative Agent (in such capacity, the “Administrative Agent”), and various Lenders, including the Lender (together with all amendments, modifications and restatements thereof, the “Credit Agreement”), and to pay interest on the principal balance of this Note outstanding from time to time at the rate or rates determined pursuant to the Credit Agreement.

Wells Fargo Bank, National Association, as

Administrative Agent and as a Lender,

and the Other Financial Institutions Listed on

Schedule A Hereto

I am the General Counsel of MDU Resources Group, Inc., a Delaware corporation (the “Company”), and in such capacity, I am familiar with (a) the negotiation, preparation, execution and delivery of that certain Credit Agreement, dated as of May 26, 2011 (the “Agreement”), by and among the Company, the several financial institutions from time to time party thereto, and Wells Fargo Bank, National Association, as Administrative Agent, and (b) the negotiation, preparation, execution and delivery of the other Loan Documents listed on Schedule B hereto (together with the Agreement, the “Loan Documents”). This opinion is furnished to you pursuant to Section 3.1(d) of the Agreement and at the instruction of the Company. All capitalized terms used but not otherwise defined herein have the meanings ascribed thereto in the Agreement.

For the purpose of rendering the opinions contained herein, I have examined and reviewed the Agreement and the other Loan Documents. I have also examined the originals, or copies certified to my satisfaction, of the Restated Certificate of Incorporation and By-Laws of the Company, resolutions adopted by the Board of Directors of the Company authorizing the execution, delivery and performance by the Company of the Agreement and the other Loan Documents, and such other corporate records of the Company and agreements, instruments and other documents as I have deemed necessary as a basis for the opinions expressed below. In my examination, I have assumed the genuineness of all signatures, other than the signatures of the Company on the Loan Documents to which it is a party, the legal capacity of natural persons, the authenticity of all documents submitted to me as originals and the conformity with original documents of all documents submitted to me as certified or photostatic copies. I have also assumed, with your consent, the due execution and delivery, pursuant to due authorization, of the Agreement by all parties thereto other than the Company and the validity and binding effect of the Agreement upon such parties.

As to any facts that I did not independently establish or verify, I have relied without independent investigation upon statements, representations and certificates of officers of the Company and as to the matters addressed therein, upon certificates or communications from public officials. As used herein, the phrase “to my knowledge” with respect to the existence or absence of facts is intended to signify that, while I have made no specific inquiry or other independent examination to determine the existence or absence of such facts, no factual information has come to my attention which causes me to believe that such facts are not accurate.

Based on and subject to the foregoing and upon such investigation as I have deemed necessary, and subject to the qualifications set forth below, it is my opinion that:

1.    The Company is a corporation duly incorporated, validly existing and in good standing under the laws of Delaware.

2.    The Company is duly qualified as a foreign corporation to transact business and is in good standing in Minnesota, Montana, North Dakota and South Dakota, and is not required, whether

by reason of ownership or leasing of property or the conduct of its business, to be qualified in any other jurisdiction, except where the failure so to qualify or to be in good standing would not result in a Material Adverse Effect.

3.    The Company has the corporate power and authority to execute, deliver and perform its obligations under the Agreement and the other Loan Documents applicable to it, and has all requisite corporate power and authority, licenses and permits to own its assets and to carry on its business as currently conducted and as contemplated to be conducted by the Agreement.

4.    The execution, delivery and performance by the Company of the Agreement and each of the other Loan Documents to which it is a party have been duly authorized by all necessary corporate action and by all necessary public utility commissions and other regulatory bodies having jurisdiction over the Company (except as noted in Schedule 4.2 of the Agreement with respect to Borrowings made after December 13, 2012), and each of the Agreement and the other Loan Documents has been duly executed and delivered by the Company.

5.    The execution, delivery and performance by the Company of the Agreement and of the other Loan Documents to which it is a party do not and will not (a) require any consent or approval of the stockholders of the Company or any authorization, consent or approval by any governmental department, commission, board, bureau, agency or instrumentality, other than Authorizing Orders set forth in Schedule 4.2 to the Agreement that (except as noted therein with respect to Borrowings made after December 13, 2012) have been obtained and are in full force and effect, (b) violate any provision of any law, rule or regulation or any order, writ, injunction or decree presently in effect having applicability to the Company or the Restated Certificate of Incorporation or By-Laws of the Company, (c) result in a breach of or constitute a default under any indenture or loan or credit agreement or any other agreement, lease or instrument to which the Company is a party or by which its properties may be bound or affected, or (d) except as provided therein, result in, or require, the creation or imposition of any Lien or other charge or encumbrance of any nature upon or with respect to any of its properties.

6.    Except as set forth in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010, or in any document subsequently filed by the Company pursuant to Section 13, 14 or 15(d) of the Exchange Act, there are no actions, suits or proceedings pending or, to my knowledge, threatened against or affecting the Company or the properties of the Company before any court or governmental department, commission, board, bureau, agency or instrumentality, which, if determined adversely to the Company, would have a Material Adverse Effect.

The opinions expressed herein are limited to the laws of the State of North Dakota and the General Corporation Law of the State of Delaware. I am a member of the Minnesota and North Dakota Bars and do not hold myself out as an expert on the laws of the States of Montana, South Dakota or Wyoming, but have made a study through counsel located in such jurisdictions or otherwise of the laws of such jurisdictions insofar as such laws are involved in the conclusions expressed in this opinion. Insofar as the opinions expressed herein relate to the General Corporation Law of the State of Delaware, or the federal laws of the United States of America, I have relied with your consent on the opinion, of even date herewith, of Cohen Tauber Spievack & Wagner P.C.

This opinion is intended solely for your use and is rendered solely in connection with the Agreement and the other Loan Documents, and without my written consent may not be (a) relied upon by you for any other purpose, or (b) relied upon by any other person or entity for any purpose, except that Cohen Tauber Spievack & Wagner P.C., special counsel to the Company, may rely on the opinions expressed herein in rendering to you their opinion of even date herewith. The opinions expressed above are limited to the law and facts in effect on the date hereof. I disclaim any obligation to advise you of

facts, circumstances, events or developments which hereafter may be brought to my attention and which might alter, affect or modify the opinions expressed herein.

I hereby consent to reliance by the Administrative Agent and the Lenders now or hereafter parties to the Agreement on the opinions expressed herein.

Administrative Agent and as a Lender,

Schedule A Hereto

We have acted as special counsel for MDU Resources Group, Inc., a Delaware corporation (the “Company”), in connection with (a) the negotiation, preparation, execution and delivery of that certain Credit Agreement, dated as of May 26, 2011 (the “Agreement”), by and among the Company, the several financial institutions from time to time party thereto, and Wells Fargo Bank, National Association, as Administrative Agent, and (b) the negotiation, preparation, execution and delivery of the other Loan Documents listed on Schedule B hereto (together with the Agreement, the “Loan Documents”). This opinion is furnished to you pursuant to Section 3.1(d) of the Agreement and at the instruction of the Company. All capitalized terms used but not otherwise defined herein have the meanings ascribed thereto in the Agreement.

For the purpose of rendering the opinions contained herein, we have examined and reviewed the Agreement and the other Loan Documents. We have also examined the originals, or copies certified to our satisfaction, of the Restated Certificate of Incorporation and By-Laws of the Company, resolutions adopted by the Board of Directors of the Company authorizing the execution, delivery and performance by the Company of the Agreement and the other Loan Documents, and such other corporate records of the Company and agreements, instruments and other documents as we have deemed necessary as a basis for the opinions expressed below. In our examination, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals and the conformity with original documents of all documents submitted to us as certified or photostatic copies. We have also assumed, with your consent, the due execution and delivery, pursuant to due authorization, of the Agreement by all parties thereto other than the Company and the validity and binding effect of the Agreement upon such parties. As to any facts that we did not independently establish or verify, we have relied without independent investigation upon statements, representations and certificates of officers of the Company and as to the matters addressed therein, upon certificates or communications from public officials.

Based on and subject to the foregoing and upon such investigation as we have deemed necessary, and subject to the qualifications set forth below, it is our opinion that:

___________, 200__

Wells Fargo Bank, National Association, as

Administrative Agent

Ladies and Gentlemen:

I am [Associate] General Counsel to MDU Resources Group, Inc., a Delaware corporation (the “Borrower”), and have represented the Borrower in connection with its execution and delivery of the Credit Agreement among the Borrower, Wells Fargo Bank, National Association, as Administrative Agent, and the other financial institutions party thereto, dated as of May 26, 2011 (the “Agreement”), and in connection with the request of the Borrower under the Agreement for a borrowing in the principal amount of $___________ to be effected on ___________, 200__ (the “Borrowing”). This opinion is being delivered to the Administrative Agent pursuant to Section 3.2(b) of the Agreement. All capitalized terms used and not otherwise defined herein have the meanings ascribed thereto in the Agreement.

I have examined the Loan Documents and such other matters of fact and law that I have deemed necessary in order to render this opinion. In such examination, I have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to me as originals, the conformity to original documents of all documents submitted to me as certified or photostatic copies, and the authenticity of such latter documents.

Based upon the foregoing, it is my opinion that:

1.    The Borrowing has been duly authorized by the Borrower’s Board of Directors pursuant to resolutions adopted thereby on ____________, which authority remains in full force and effect on the date hereof.

2.    No authorization, consent or approval by any governmental department, commission, board, bureau, agency or instrumentality, other than the Authorizing Orders which have been obtained and are in full force and effect and copies of which Authorizing Orders have been delivered to the Administrative Agent, is required in connection with the Borrowing.

3.    Without limiting the generality of the foregoing, the Borrowing complies with all applicable requirements of each applicable resolution of the Borrower’s Board of Directors and each applicable Authorizing Order, including but not limited to any applicable limitation on the aggregate amount of short-term or long-term debt that the Borrower may have outstanding at any one time and any limitation on the rate of interest that may be applicable thereto.

I am a member of the North Dakota Bar and do not hold myself out as an expert on the laws of any other state, but I have made a study of the laws of such states insofar as such laws are involved in the conclusions stated in this opinion.

This opinion is rendered to you in connection with the above-described transaction. This opinion may not be relied upon by you for any other purpose, or relied upon by or furnished to any other person, firm or corporation without my prior written consent.

Very truly yours,
