not later than 1:30 p.m. on the date that the requested Borrowing is to occur, or, if the requested Borrowing is to bear interest at a LIBO Rate, the close of business on the day that the request is received, the Agent will notify the Banks of the amount of the requested Borrowing, the amount of each Bank’s Advance with respect thereto, and, if applicable, the fact that the Borrower has elected a LIBO Rate and the Interest Period selected by the Borrower. Upon fulfillment of the applicable conditions set forth in Article III, each Bank shall remit its Percentage of the requested Borrowing to the Agent in immediately available funds. So long as a Bank receives notice of the requested Borrowing prior to 1:30 p.m. on the date that the requested Borrowing is to occur, or, if the requested Borrowing is to bear interest at a LIBO Rate, the close of business on the day that the request is received, that Bank will make its Advance with respect to that Borrowing available to the Agent by wire transfer of immediately available funds to the Agent not later than 4:00 p.m. on the date called for in such notice. Prior to the close of business on the day of the requested Borrowing, the Agent shall disburse such funds by crediting the same to the Borrower’s demand deposit account maintained with the Agent or in such other manner as the Agent and the Borrower may from time to time agree. The Agent shall have no obligation to disburse the requested Borrowing if any condition set forth in Article III has not been satisfied on the day of the requested Borrowing. Each Borrowing shall be in the amount of $1,000,000 or an integral multiple thereof; provided, however, that any portion of such Borrowing bearing interest at a LIBO Rate must be in the amount of $5,000,000 or an integral multiple of $1,000,000 greater than $5,000,000. The Borrower shall promptly confirm each telephonic request for an Advance by executing and delivering an appropriate confirmation certificate to the Agent. However, the Borrower shall be obligated to repay all Advances for which it actually received the moneys (including but not limited to all Advances the proceeds of which were deposited in any account of the Borrower) or in respect of which the Agent reasonably believed the person requesting the same to be authorized to do so, notwithstanding the fact that the person requesting the same was not in fact authorized so to do. Any request for an Advance shall be deemed to be a representation that the statements set forth in Section 3.2 are correct.

Section 2.3 Interest

   (a) The Notes shall bear interest on the unpaid principal amount thereof from the date thereof until paid as set forth in this Section 2.3.

   (b) Unless the Borrower elects a LIBO Rate pursuant to this Section, the principal balance of each Note shall bear interest at the Floating Rate.

   (c) At the election of the Borrower, which may be exercised from time to time, the Borrower may request in writing or by telephone that a LIBO Rate be applicable for the portion of the outstanding principal balance of the Notes (including any Advance requested or to be requested) and for the Interest Period indicated by the Borrower in its request. The portion of the outstanding balance of the Notes for which a LIBO Rate is requested (i) must be in the amount (as to all Notes combined) of $5,000,000 or an integral multiple of $1,000,000 greater than $5,000,000, and (ii) if

-14-

such request relates to Advances already outstanding, must, on the first day of the applicable Interest Period, either (1) bear interest at the Floating Rate, or (2) bear interest at a LIBO Rate with respect to which the Interest Period expires on such first day. In no event may the Borrower select an Interest Period extending beyond the then-applicable Maturity Date. A request for a LIBO Rate (i) must be received by the Agent before 10:00 a.m. on the day three Business Days before the first day of the proposed Interest Period (and the Agent shall give the Banks prompt notice thereof), and (ii) may not be rescinded by the Borrower after such request has been made. Subject to the terms and conditions set forth herein, the applicable LIBO Rate shall (subject to fluctuations in the applicable LIBO Rate Margin) be the interest rate applicable for the proposed Interest Period to the portion of the outstanding principal balance of the Note to which the LIBO Rate request related (and the remaining part of the principal balance of the Note, if any, shall continue to bear interest at the rate or rates previously applicable to such amounts). At the termination of such Interest Period, the interest rate applicable to the portion of the principal balance of the Note to which the LIBO Rate request was applicable shall revert to the Floating Rate unless a new LIBO Rate request is made by the Borrower in accordance with this Agreement. Notwithstanding anything to the contrary in this Section, (i) the Agent shall have no obligation to permit the application of a LIBO Rate for any Interest Period if any Bank, in its sole discretion, determines that deposits in amounts equal to the requested amount and maturing at the end of the proposed Interest Period are not readily available to such Bank from major banks in the London interbank market and (ii) without the consent of the Required Banks, the Agent will not permit the application of a LIBO Rate for any Interest Period if a Default or Event of Default has occurred and is continuing when the request for the LIBO Rate is made. Absent manifest error, the records of the Agent shall be conclusive evidence as to the amount of the Note bearing interest at a LIBO Rate, the applicable LIBO Rate and the date on which the Interest Period applicable to such LIBO Rate expires.

Section 2.4 Limitation of Outstandings.

In no event shall the aggregate Outstandings at any time prior to the Commitment Termination Date exceed the aggregate Commitment Amounts.

Section 2.5 Principal and Interest Payment Dates.

   (a) Interest. Interest accruing at the Floating Rate on the principal balance of the Notes shall be due and payable on the last day of each March, June, September and December and on the Maturity Date. Interest accruing at a LIBO Rate shall be due and payable on the last day of the applicable Interest Period or, if an Interest Period is in excess of three months, on the date that is three months after the beginning of the Interest Period and after each such interest payment date thereafter, and on the last day of the Interest Period and on the Maturity Date.

-15-

   (b) Principal. The principal balance of the Notes shall be due and payable in full on the Maturity Date.

Section 2.6 Level Status and Margins.

   (a) The Borrower’s Level Status shall be determined on the basis of the rating accorded the Reference Debt by S&P and Moody’s, in accordance with the following table:

If the ratings applied by S&P and Moody’s differ such that they do not fall within a single column in the table set forth above, (i) if the applicable columns are adjacent to each other, the Level Status in effect shall be based on the leftmost of the applicable columns, (ii) if the applicable columns are separated by a single column, the Level Status in effect shall be based on the column between those two columns, and (iii) if the applicable columns are separated by two or more columns, the Level Status in effect shall be based on the column to the immediate left of the rightmost applicable column.

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

-16-

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

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

Section 2.7 Letters of Credit.

   (a) The Borrower may from time to time , on or prior to the Commitment Termination Date, request that the Issuing Bank issue one or more irrevocable standby letters of credit (each, a “Letter of Credit”) for the account of the Borrower or any of its Subsidiaries. No Letter of Credit shall be issued if (i) the face amount of that Letter of Credit, together with the sum of the then-applicable L/C Amount and the aggregate principal balance of the Notes then outstanding, would exceed the aggregate Commitment Amounts, or (ii) the face amount of that Letter of Credit, together with the then-applicable L/C Amount, would exceed the L/C Sublimit.

   (b) At least three days prior to the issuance of each Letter of Credit, the Borrower shall execute a letter of credit application and reimbursement agreement in the Issuing Bank’s standard form, as required by the Issuing Bank.

   (c) Each Letter of Credit shall be issued in a form acceptable to the Issuing Bank. Unless otherwise approved by all of the Banks, no Letter of Credit shall have an initial or any renewal term ending more than one year after the date of issuance.

   (d) A fee shall be due and payable to the Agent for the benefit of the Banks upon issuance of each Letter of Credit, computed at an annual rate equal to the LIBO Rate Margin applied to the undrawn face amount of that Letter of Credit outstanding from time to time, from and including the date of issuance of that Letter of Credit

-17-

until the expiration thereof, payable in arrears on the last day of each calendar quarter and on the Maturity Date and, if later, the expiration date of such Letter of Credit. In addition, the Borrower shall pay or reimburse the Issuing Bank for such normal and customary costs and expenses as are incurred or charged by the Issuing Bank in issuing, effecting payment under, amending or otherwise processing or administering any Letter of Credit.

   (e) The Borrower shall be irrevocably and unconditionally obligated to pay the amount of each draft drawn under any Letter of Credit (including any Letter of Credit issued for the account of a Subsidiary) to the Issuing Bank on demand (or, if demand is not earlier made, on the Commitment Termination Date), together with interest at the Floating Rate from the date that such draft is paid by the Issuing Bank until payment of such amount in full; provided that the Borrower shall not be precluded from asserting a claim against the Issuing Bank for direct (but not consequential) damages suffered by the Borrower to the extent caused by the gross negligence or willful misconduct of the Issuing Bank in determining whether a request presented under any Letter of Credit issued by it complied with the terms of such Letter of Credit. The Issuing Bank shall provide notice to the Borrower of payment of the draft within one Business Day of such payment. The Issuing Bank may (at its option) charge any deposit account maintained by the Borrower with the Issuing Bank for the amount of any draft drawn under a Letter of Credit.

   (f) Each Bank shall be deemed to hold a participation interest in each Letter of Credit equal to that Bank’s Percentage of the face amount of that Letter of Credit. If the Issuing Bank makes any payment pursuant to the terms of any Letter of Credit and is not promptly reimbursed, the Issuing Bank may request that each other Bank pay such Bank’s Percentage of the unreimbursed amount. Upon receipt of any such request prior to 1:30 p.m. on a Business Day, the recipient shall be unconditionally and irrevocably obligated to pay its Percentage of the unreimbursed amount to the Issuing Bank in immediately available funds prior to 3:00 p.m. on such date. Notices received after 1:30 p.m. shall be deemed to have been received on the following Business Day. If payment is not made by a Bank when due hereunder, interest on the unpaid amount shall accrue from and including the date of the Issuing Bank’s request to the date of payment at the Federal Funds Rate. After making any payment to the Issuing Bank under this subsection in connection with a particular Letter of Credit, a Bank shall be entitled to participate to the extent of its Percentage in the related reimbursements received by the Issuing Bank from the Borrower or otherwise. Upon receiving any such reimbursement, the Issuing Bank will distribute to each Bank its Percentage of such reimbursement. At the option of the Agent, payment by the Banks hereunder may be deemed an Advance in accordance with Section 2.1 and payable under the Notes.

   (g) Unless otherwise agreed by each Bank in writing, the Borrower shall deposit in the Cash Collateral Account, on the Commitment Termination Date, an

-18-

amount equal to the then-applicable L/C Amount, less the balance (if any) then outstanding in the Cash Collateral Account.

Section 2.8 Facility, Utilization and Term Loan Fees.

     (a) The Borrower shall pay to the Agent, for the benefit of the Banks, a facility fee at an annual rate equal to the then-applicable Facility Fee Rate applied to the aggregate Commitment Amounts outstanding hereunder from the date of this Agreement through the Maturity Date.

     (b) The Borrower shall pay to the Agent, for the benefit of the Banks, a utilization fee at an annual rate equal to the then-applicable Utilization Fee Rate applied to the average daily Outstandings. The Utilization Fee Rate in effect on any day shall be an annual rate determined on the basis of the Outstandings Percentage and Level Status on that day, in accordance with the following table:

     Notwithstanding the foregoing, if the Maturity Date is extended pursuant to Section 2.20, the applicable Utilization Fee Rate set forth in the rightmost column above will apply from and after the Commitment Termination Date, regardless of the Outstandings Percentage.

     (c) If the Maturity Date is extended pursuant to Section 2.20, the Borrower shall pay to the Agent, for the benefit of the Banks, a term loan fee as set forth in this Section. The term loan fee shall accrue from and after the Commitment Termination Date through payment of the Notes in full at an annual rate equal to the then-applicable Term Loan Fee Rate applied to the average daily outstanding principal amount of the Notes. The Term Loan Fee Rate in effect on any day shall be an annual rate determined on the basis of the Level Status on that day, in accordance with the following table:

-19-

     (d) The facility fee, utilization fee and term loan fee set forth in this Section shall be due and payable quarterly in arrears on the last day of each March, June, September and December. Any facility, utilization and term loan fees remaining unpaid on the Maturity Date shall be due and payable on that date.

Section 2.9 Other Fees.

The Borrower shall pay to the Agent (i) for the benefit of the Banks, the upfront fee set forth in the Fee Letters, and (ii) for the Agent’s own account and not for the benefit of the Banks, certain additional fees in the amounts set forth in the Fee Letters.

Section 2.10 Termination or Reduction of the Commitment.

The Borrower shall have the right at any time and from time to time upon three Business Days’ prior notice to the Agent (which shall promptly notify the Banks) permanently to terminate the Commitments in whole or permanently to reduce the Commitment Amounts in part, without penalty or premium, provided that (i) the Commitments may not be terminated while any Advance or L/C Amount remains outstanding, (ii) each partial reduction shall be in the aggregate amount of $5,000,000 or a multiple thereof, (iii) any partial reduction of the Commitment Amounts shall be pro rata as to each Bank in accordance with that Bank’s Percentage, and (iv) no reduction shall reduce the Commitment Amounts to an amount less than the sum of the aggregate Advances and the L/C Amount outstanding (after giving effect to any prepayments of Advances to be made on or prior to the effective date of such reduction) at the time.

Section 2.11 Voluntary Prepayments.

The Borrower may prepay the Notes in whole or in part, without penalty or premium, at any time and from time to time; provided that (i) any prepayment by the Borrower hereunder shall be applied pro rata to the prepayment of each Bank’s Note, (ii) any prepayment of Notes shall include accrued interest on the portion of the principal balance prepaid, (iii) any prepayment of any portion of the principal balance of the Notes which, at the time of such prepayment, bears interest at a LIBO Rate shall be accompanied by compensation as

-20-

specified in Section 2.16(b), and (iv) each prepayment of the Notes (other than prepayment of the Notes in full) shall be in the principal amount of $1,000,000 or more, except that no prepayment of any portion of the Notes bearing interest at a LIBO Rate may be made in a principal amount less than $5,000,000. Each partial prepayment of principal on the Notes shall be applied, first, to that portion of such Notes bearing interest at the Floating Rate, and, second, to that portion of such Notes bearing interest at a LIBO Rate; provided that, so long as no Default or Event of Default has occurred and is continuing, the Borrower may direct such prepayment to be applied in an alternative order.

Section 2.12 Computation of Interest and Fees.

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

Section 2.13 Payments.

All payments of principal of and interest on the Notes, of L/C Amounts and of fees hereunder shall be made to the Agent in immediately available funds, without setoff or counterclaim. Payments received after noon on any day shall be deemed received on the next succeeding Business Day. The Borrower agrees that the amount shown on the books and records of each Bank as being the principal balance of that Bank’s Note, if any, shall be prima facie evidence of such principal balance. The Borrower hereby authorizes the Agent to charge against the Borrower’s account with the Agent an amount equal to the accrued interest and fees from time to time due and payable to the Agent and the Banks under the Notes or hereunder, or (at the Banks’ option) to effect a Borrowing in such amount, all without receipt of any request for such charge or Borrowing.

Section 2.14 Payment on Nonbusiness Days.

Whenever any payment to be made hereunder or under the Notes shall be stated to be due on a day other than a Business Day, such payment may be made on the next succeeding Business Day, and such extension of time shall in each case be included in the computation of payment of interest on such Note or the fees hereunder, as the case may be.

Section 2.15 Use of Advances and Letters of Credit.

The proceeds of each Borrowing, and each Letter of Credit, shall be used by the Borrower for its general corporate purposes (including commercial paper backup). Notwithstanding the foregoing, in no event shall the proceeds of any Borrowing or any Letter of Credit be used by the Borrower to finance the acquisition of 5% or more of any class of the capital stock of any corporation unless, prior to making such acquisition, the Borrower has obtained written approval for such acquisition from the board of directors of such corporation. The limitation set forth in the preceding sentence is in addition to, and not in lieu of, the restriction set forth in Section 4.9.

-21-

Section 2.16 Yield Protection; Funding Indemnification.

In addition to any interest payable on Advances made hereunder and any fees or other amounts payable hereunder, the Borrower agrees:

     (a) If at any time after the date hereof any adoption of or change in any applicable law, rule or regulation or the interpretation or administration thereof by any governmental authority (including, without limitation, Regulation D of the Federal Reserve Board):

     (b) The Borrower shall also compensate any Bank, upon written request by that Bank (which request shall set forth the basis for requesting such amounts), for all losses and expenses in respect of any interest or other consideration paid by that Bank to lenders of funds borrowed by it or deposited with it to maintain any portion of the

-22-

Section 2.17 Taxes.

     (a) All payments made by the Borrower to the Agent or any Bank (herein any “Payee”) under or in connection with this Agreement or the Notes shall be made without any setoff or other counterclaim, and free and clear of and without deduction for or on account of any present or future taxes now or hereafter imposed by any governmental or other authority, except to the extent that such deduction or withholding is compelled by law. As used herein, the term “Taxes” shall include all income, excise and other taxes of whatever nature (other than taxes based on or measured by the net income of the Payee (or franchise taxes in lieu thereof) and imposed by the government or other authority of the country, state or political subdivision in which such Payee is incorporated or in which its principal executive office or the office through which the Payee is acting is located (“Excluded Taxes”)) as well as all levies, imposts, duties, charges, or fees of whatever nature. If the Borrower is compelled by law to make any such deductions or withholdings it will:

-23-

     (b) If any Taxes otherwise payable by the Borrower pursuant to Section 2.17(a) are directly asserted against any Payee, such Payee may pay such Taxes and the Borrower promptly shall reimburse such Payee to the full extent otherwise required by such paragraph. The obligations of the Borrower under this Section 2.17 shall survive any termination of this Agreement. Each Bank by its execution of this Agreement represents (and each additional Bank by its execution of any Assignment Certificate pursuant to Section 8.10 shall be deemed to represent) to each other Bank, the Agent and the Borrower that if such Bank or additional Bank is organized under the laws of any jurisdiction other than the United States or any state thereof, such Bank or additional Bank has furnished to the Agent and the Borrower either U.S. Internal Revenue Service Form W-8BEN, or U.S. Internal Revenue Service Form W-8ECI, as applicable (wherein such Bank claims entitlement to complete exemption from U.S. Federal withholding tax on all interest payments hereunder).

     (c) The amount that the Borrower shall be required to pay to any Bank pursuant to Section 2.17(a) or 2.17(b) shall be reduced by the amount of any offsetting tax benefit which such Bank receives as a result of the Borrower’s payment to the relevant authorities as reasonably determined by such Bank; provided, however, that (i) such Bank shall be the sole judge of the amount of such tax benefit and the date on which it is received, (ii) no Bank shall be obliged to disclose information regarding its tax affairs or tax computations, (iii) nothing herein shall interfere with a Bank’s right to manage its tax affairs in whatever manner it sees fit, and (iv) if such Bank shall subsequently determine that it has lost the benefit of all or a portion of such tax benefit, the Borrower shall promptly remit to such Bank the amount certified by such Bank to be the amount necessary to restore such Bank to the position it would have been in if no payment had been made pursuant to this Section 2.17(c).

     (d) If the U.S. Internal Revenue Service or any other governmental authority of the United States or any other country or any political subdivision thereof asserts a claim that the Agent or the Borrower did not properly withhold tax from amounts paid to or for the account of any Bank (because the appropriate form was not delivered or properly completed, because such Bank failed to notify the Agent or the Borrower of a change in circumstances which rendered its exemption from withholding ineffective, or for any other reason), such Bank shall indemnify the Agent or the Borrower, as applicable, fully for all amounts paid, directly or indirectly, by the Agent or the Borrower, as applicable, as tax, withholding therefor, or otherwise, including penalties and interest, and including taxes imposed by any jurisdiction on amounts payable to the Agent or the Borrower, as applicable, under this subsection, together with all costs and expenses related thereto (including attorneys fees and time charges of attorneys for the Agent or the Borrower, as applicable, which attorneys may be employees of the Agent or the Borrower, as applicable). The obligations of the Bank under this Section 2.17(d) shall survive the payment of the Obligations and termination of this Agreement.

-24-

Section 2.18 Capital Adequacy.

If any Bank determines at any time that its Return has been reduced as a result of any Capital Adequacy Rule Change, that Bank may require the Borrower to pay it the amount necessary to restore its Return to what it would have been had there been no Capital Adequacy Rule Change. For purposes of this Section:

     (a) “Return”, for any period, means the percentage determined by dividing (i) the sum of interest and ongoing fees earned by a Bank under this Agreement during such period, by (ii) the average capital that Bank or its holding company is required to maintain during such period as a result of its being a party to this Agreement, as determined by that Bank based upon its total capital requirements and a reasonable attribution formula that takes account of the Capital Adequacy Rules then in effect. Return may be calculated for each calendar quarter and for the shorter period between the end of a calendar quarter and the date of termination in whole of this Agreement.

     (b) “Capital Adequacy Rule” means any law, rule, regulation or guideline regarding capital adequacy that applies to any Bank, or the interpretation thereof by any governmental or regulatory authority. Capital Adequacy Rules include rules requiring financial institutions to maintain total capital in amounts based upon percentages of outstanding loans, binding loan commitments and letters of credit.

     (c) “Capital Adequacy Rule Change” means any change in any Capital Adequacy Rule occurring after the date of this Agreement, but the term does not include any changes in applicable requirements that at the date hereof are scheduled to take place under the existing Capital Adequacy Rules or any increases in the capital that any Bank is required to maintain to the extent that the increases are required due to a regulatory authority’s assessment of the financial condition of that Bank.

     (d) “Bank” includes (but is not limited to) the Banks, as defined elsewhere in this Agreement; any participant in the loans made hereunder (to the extent provided in Section 8.11 only); and any bank holding company with respect to any of the foregoing.

The initial notice sent by a Bank shall be sent as promptly as practicable after that Bank learns that its Return has been reduced, shall include a demand for payment of the amount necessary to restore that Bank’s Return for the quarter in which the notice is sent and, if applicable, the preceding quarter, and shall state in reasonable detail the cause for the reduction in its Return and its calculation of the amount of such reduction. Thereafter, that Bank may send a new notice with respect to each calendar quarter setting forth the calculation of the reduced Return for that quarter and including a demand for payment of the amount necessary to restore its Return for that quarter. In such event, the Borrower shall pay the Bank such amount within 30 days after demand by such Bank. A Bank’s calculation in any such notice shall be conclusive and binding absent demonstrable error. A Bank shall not make demand hereunder unless that Bank is generally imposing such increased costs on its

-25-

similarly situated customers. No Bank may demand any compensation hereunder more than 45 days following the end of the quarter for which compensation is sought.

Section 2.19 Mandatory Assignment of Bank’s Interest.

If any Bank delivers to the Borrower a demand for compensation pursuant to Section 2.16(a), a demand for payment pursuant to Section 2.17 or 2.18 or if at any time the long-term unenhanced credit rating of any Bank falls below Baa2 from Moody’s or below BBB from S&P or if such Bank is no longer rated by S&P or Moody’s, the Borrower may (so long as no Default or Event of Default has occurred and is continuing) at its expense require such Bank to assign, in whole and in accordance with Section 8.10 (including the execution of an Assignment Certificate and all other applicable documents, and the payment of any fees required under Section 8.10), all of its rights and obligations hereunder and under such Bank’s Note, including but not limited to such Bank’s Commitment, to an Eligible Lender identified by the Borrower and willing to become a Bank hereunder. Such Bank may be an existing Bank hereunder. Notwithstanding the foregoing, the Borrower may not compel the resignation of any Bank as the Agent except as provided in Section 8.9.

Section 2.20 Extension of Maturity Date.

Not earlier than the 10th Business Day prior to the Commitment Termination Date and not later than the 3rd Business Day prior to the Commitment Termination Date, the Borrower may, upon notice to the Agent (who shall promptly notify the Banks), request a one year extension of the Maturity Date. So long as no Default or Event of Default exists at the time of such request or at any time thereafter through the Commitment Termination Date, the Maturity Date shall be automatically extended to the first anniversary of the Commitment Termination Date if the Borrower makes such request. Extension of the Maturity Date shall not extend the Commitment Termination Date.

Upon the occurrence of an Event of Default or at any time thereafter until such Event of Default is waived by the Required Banks or cured, the Agent may, with the consent of the Required Banks, and shall, upon the request of the Required Banks, exercise any or all of the following rights and remedies:

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

     (b) The 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) If any Letter of Credit remains outstanding, the Agent may, by notice to the Borrower, require the Borrower to deposit in the Cash Collateral Account immediately available funds equal to the aggregate face amount of all such outstanding Letters of Credit (less any amounts then on deposit in the Cash Collateral Account).

     (d) The Banks may, without notice to the Borrower and without further action, apply any and all money owing by any Bank to the Borrower to the payment of the Notes then outstanding, including interest accrued thereon, and of all other sums then owing by the Borrower hereunder. For purposes of this paragraph (d), “Bank” means the Banks, as defined elsewhere in this Agreement, and any participant in the loans made hereunder; provided, however, that each such participant, by exercising its rights under this paragraph (d), agrees that it shall be obligated under Section 8.4 with respect to such payment as if it were a Bank for purposes of that Section.

-42-

     (e) The Agent may exercise and enforce all rights and remedies available to it in respect of the Cash Collateral Account.

     (f) The Agent and the Banks 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(j) hereof (whether or not such Event of Default also arises under Section 7.1(i) hereof), the Commitments shall terminate and 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.

Section 7.3 Pledge of Cash Collateral Account.

The Borrower hereby pledges, and grants the Agent, as agent for the Banks, including the Issuing Bank, a security interest in, all sums held in the Cash Collateral Account from time to time and all proceeds thereof as security for the payment of all amounts due and to become due from the Borrower to the Issuing Bank, the Agent and/or the Banks pursuant to this Agreement, including but not limited to both principal of and interest on the Notes and all renewals, extensions and modifications thereof and any notes issued in substitution therefor, and specifically including the Borrower’s obligation to reimburse the Issuing Bank for any amount drawn under any Letter of Credit, whether such reimbursement obligation arises directly under this Agreement or under a separate reimbursement agreement. Upon request of the Borrower, the Agent shall permit the Borrower to withdraw from the Cash Collateral Account, so long as no Default or Event of Default then exists, the lesser of (i) the Excess Balance (as defined below), or (ii) the balance of the Cash Collateral Account. If a Default or Event of Default then exists, the Agent shall, upon the request of the Borrower, apply the Excess Balance to the payment of the Obligations; provided further that if there are no Obligations (other than Letters of Credit) outstanding, the Agent shall, upon request of the Borrower, release to the Borrower an amount by which the balance in the Cash Collateral Account exceeds 110% of the L/C Amount. As used herein, “Excess Balance” means (A) after the Commitment Termination Date, the amount by which the balance of the Cash Collateral Account exceeds the L/C Amount, and (B) prior to the Commitment Termination Date, the balance of the Cash Collateral Account. The Agent shall have full control of the Cash Collateral Account, and, except as set forth above, the Borrower shall have no right to withdraw the funds maintained in the Cash Collateral Account.

ARTICLE VIII
The Agent

Section 8.1 Authorization.

Each Bank and the holder of each Note irrevocably appoints and authorizes the Agent to act on behalf of such Bank or holder to the extent provided herein or in any document or

-43-

instrument delivered hereunder or in connection herewith, and to take such other action as may be reasonably incidental thereto.

Section 8.2 Distribution of Payments and Proceeds.

     (a) After deduction of any costs of collection as hereinafter provided, the Agent shall remit to each Bank that Bank’s Percentage of all payments of principal, interest, Letter of Credit fees payable under Section 2.7(d) and facility, utilization, and term loan fees payable under Section 2.8 that are received by the Agent under the Loan Documents. Each Bank’s interest in the Loan Documents shall be payable solely from payments, collections and proceeds actually received by the Agent under the Loan Documents; and the Agent’s only liability to the Banks hereunder shall be to account for each Bank’s Percentage of such payments, collections and proceeds in accordance with this Agreement. If the Agent is ever required for any reason to refund any such payments, collections or proceeds, each Bank will refund to the Agent, upon demand, its Percentage of such payments, collections or proceeds, together with its Percentage of interest or penalties, if any, payable by the Agent in connection with such refund. The Agent may, in its sole discretion, make payment to the Banks in anticipation of receipt of payment from the Borrower. If the Agent fails to receive any such anticipated payment from the Borrower, each Bank shall promptly refund to the Agent, upon demand, any such payment made to it in anticipation of payment from the Borrower, together with interest for each day on such amount until so refunded at a rate equal to the Federal Funds Rate for each such date.

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

Section 8.3 Expenses.

All payments, collections and proceeds received or effected by the Agent may be applied, first, to pay or reimburse the Agent for all costs, expenses, damages and liabilities at any time incurred by or imposed upon the Agent in connection with this Agreement or any other Loan Document (including but not limited to all reasonable attorney’s fees, foreclosure expenses and advances made to protect the security of collateral, if any, but excluding any costs, expenses, damages or liabilities arising from the gross negligence or willful misconduct of the Agent). If the Agent does not receive payments, collections or proceeds

-44-

from the Borrower or its properties sufficient to cover any such costs, expenses, damages or liabilities within 30 days after their incurrence or imposition, each Bank shall, upon demand, remit to the Agent its Percentage of the difference between (i) such costs, expenses, damages and liabilities, and (ii) such payments, collections and proceeds.

Section 8.4 Payments Received Directly by Banks.

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

Section 8.5 Indemnification.

The Agent shall not be required to do any act hereunder or under any other document or instrument delivered hereunder or in connection herewith, or to prosecute or defend any suit in respect of this Agreement or the Notes or any documents or instrument delivered hereunder or in connection herewith unless indemnified to its satisfaction by the holders of the Notes against loss, cost, liability and expense (other than any such loss, cost, liability or expense attributable to the Agent’s own gross negligence or willful misconduct). If any indemnity furnished to the Agent for any purpose shall, in the opinion of the Agent, be insufficient or become impaired, the Agent may call for additional indemnity and not commence or cease to do the acts indemnified against until such additional indemnity is furnished.

Section 8.6 Exculpation.

     (a) The Agent shall be entitled to rely upon advice of counsel concerning legal matters, and upon this Agreement, any Loan Document and any schedule, certificate, statement, report, notice or other writing which it in good faith believes to be genuine or to have been presented by a proper person. Neither the Agent nor any of its directors, officers, employees or agents shall (a) be responsible for any recitals, representations or warranties contained in, or for the execution, validity, genuineness, effectiveness or enforceability of this Agreement, any Loan Document, or any other instrument or document delivered hereunder or in connection herewith, (b) be responsible for the validity, genuineness, perfection, effectiveness, enforceability, existence, value or enforcement of any collateral security, (c) be under any duty to inquire into or pass upon any of the foregoing matters, or to make any inquiry concerning the performance by the Borrower or any other obligor of its obligations, or (d) in any event, be liable as such for any action taken or omitted by it or them, except

-45-

for its or their own gross negligence or willful misconduct. The appointment of Wells Fargo as Agent hereunder shall in no way impair or affect any of the rights and powers of, or impose any duties or obligations upon, Wells Fargo in its individual capacity.

     (b) The term, “agent”, is used herein in reference to the Agent merely as a matter of custom. It is intended to reflect only an administrative relationship between the Agent and the Banks, in each case as independent contracting parties. However, the obligations of the Agent shall be limited to those expressly set forth herein. In no event shall the use of such term create or imply any fiduciary relationship or any other obligation arising under the general law of agency, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against the Agent.

Section 8.7 Agent and Affiliates.

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

Section 8.8 Credit Investigation.

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

Section 8.9 Resignation.

The Agent may resign as such at any time upon at least 30 days’ prior notice to the Borrower and the Banks. In the event of any resignation of the Agent, the Required Banks shall as promptly as practicable appoint a Bank as a successor Agent; provided, however, that so long as no Default or Event of Default has occurred and is continuing at such time, no such successor Agent may be appointed without the prior written consent of the Borrower. If no such successor Agent shall have been so appointed by the Required Banks and shall have accepted such appointment within 30 days after the resigning Agent’s giving of notice of resignation, then the resigning Agent may, on behalf of the Banks, appoint a Bank as a successor Agent, which shall be a commercial bank organized under the laws of the United States of America or of any State thereof. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon be entitled to receive from the prior Agent such documents of transfer and assignment as such successor Agent

-46-

may reasonably request and the resigning Agent shall be discharged from its duties and obligations under this Agreement. After any resignation pursuant to this Section, the provisions of this Section shall inure to the benefit of the retiring Agent as to any actions taken or omitted to be taken by it while it was an Agent hereunder.

Section 8.10 Assignments.

     (a) Any Bank may, at any time, assign a portion of its Notes and Commitment to an Eligible Lender (an “Applicant”) on any date (the “Adjustment Date”) selected by such Bank, subject to the terms and provisions of this Section 8.10. The aggregate principal amount of the Note and Commitment so assigned in any assignment shall be not less than $5,000,000, and the assigning Bank shall retain at least $5,000,000 of such Note and Commitment for its own account; provided, however, that the foregoing restriction shall not apply to a Bank assigning its entire Note and Commitment to the Applicant. Any Bank proposing an assignment hereunder shall give notice of such assignment to the Agent and the Borrower at least ten Business Days prior to such assignment (unless the Agent consents to a shorter period of time). Such notice shall specify the identity of such Applicant and the Percentage which it proposes that such Applicant acquire (which Percentage shall be the same for the Commitment and the Note held by the assigning Bank). Any assignment hereunder may be made only with the prior written consent of the Agent and the Borrower; provided, however, that (i) in no event shall such consent be unreasonably withheld, and (ii) the consent of the Borrower shall not be required if a Default or Event of Default has occurred and is continuing at the time of such assignment.

     (b) Subject to the prior written consent of the Agent and the Borrower (if applicable), to confirm the status of an Applicant as a party to this Agreement and to evidence the assignment of the applicable portion of the assigning Bank’s Commitment and Notes in accordance herewith:

-47-

Upon the execution and delivery of such Assignment Certificate and such Notes, (a) this Agreement shall deemed to be amended to the extent, and only to the extent, necessary to reflect the addition of such Additional Bank and the resulting adjustment of Percentages arising therefrom, (b) the assigning Bank shall be relieved of all obligations hereunder to the extent of the reduction of all obligations hereunder and to the extent of the reduction of such Bank’s Percentage, and (c) the Additional Bank shall become a party hereto and shall be entitled to all rights, benefits and privileges accorded to a Bank herein and in each other document or instrument executed pursuant hereto and subject to all obligations of a Bank hereunder, including the right to approve or disapprove actions which, in accordance with the terms hereof, require the approval of the Required Banks or all Banks, and the obligations to make Advances hereunder. In the case of an assignment covering all of the assigning Bank’s rights, benefits and obligations under this Agreement, such Bank shall cease to be a Bank hereunder but shall continue to be entitled to the benefits of, and subject to, those provisions of this Agreement and the other Loan Documents which survive payment of the Obligations and termination of the Loan Documents.

     (c) In order to facilitate the addition of Additional Banks hereto, the Borrower shall (subject to the written agreement of any prospective Additional Bank to be subject to the confidentiality provisions of Section 8.13) provide all reasonable assistance requested by each Bank and the Agent relating thereto, which shall not require undue effort or expense on the part of the Borrower, including, without limitation, the furnishing of such written materials and financial information regarding the Borrower as any Bank or the Agent may reasonably request, and the participation by officers of the Borrower in a meeting or teleconference call with any Applicant upon the reasonable request upon reasonable notice of any Bank or the Agent.

     (d) Notwithstanding any other provision hereof:

-48-

provided, however, that any partial sale, assignment, transfer or negotiation pursuant to this Section shall be pro rata as to all of the Commitment, Note and Advances transferred.

     (e) Simultaneous with any assignment under this Section, the Bank making such assignment shall pay the Agent a transfer fee in the amount of $3,500.

     (f) Notwithstanding anything to the contrary contained herein, any Bank (a “Granting Bank”) may grant to a special purpose funding vehicle (an “SPC”) of such Granting Bank, identified as such in writing from time to time by the Granting Bank to the Agent and the Borrower, the option to provide to the Borrower all or any part of any Advance that such Granting Bank would otherwise be obligated to make to the applicable Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Advance, (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Advance, the Granting Bank shall be obligated to make such Advance pursuant to the terms hereof, (iii) such Granting Bank’s other obligations under this Agreement shall remain unchanged, (iv) such Granting Bank shall remain solely responsible to the other parties hereto for the performance of such obligations, and (v) the Borrower, the Agent and the other Banks shall continue to deal solely and directly with such Granting Bank in connection with such Granting Bank’s rights and obligations under this Agreement (including any rights and obligations assigned to such SPC). The making of an Advance by an SPC hereunder shall be deemed to utilize the Commitment of the applicable Granting Bank to the same extent, and as if, such Advance were made by such Granting Bank. Each party hereto hereby agrees that no

-49-

SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the applicable Granting Bank). All notices hereunder to any Granting Bank or the related SPC, and all payments in respect of the Obligations due to such Granting Bank or the related SPC, shall be made to such Granting Bank. In addition, each Granting Bank shall vote as a Bank hereunder without giving effect to any assignment under this paragraph (f), and no SPC shall have any vote as a Bank under this Agreement for any purpose. In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding senior indebtedness of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary contained in this Section 8.10, any SPC may (i) with notice to, but without the prior written consent of, the Borrower or the Agent and without paying any transfer fee therefor, assign all or a portion of its interests in its right to repayment of any Advances to its Granting Bank or to any financial institutions providing liquidity and/or credit support to or for the account of such SPC to fund the Advances made by such SPC or to support the securities (if any) issued by such SPC to fund such Advances and (ii) disclose on a confidential basis, to the extent such disclosure would be permitted under Section 8.13 as if such SPC were a Bank, any non-public information relating to its Advances to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. No amendment to this paragraph (f) that affects the rights of an SPC that has made an advance hereunder shall be effective without the consent of such SPC.

     (g) Notwithstanding any other provision of this Agreement, any Bank may at any time create a security interest in all or any portion of its rights under this Agreement and that Bank’s Note in favor of any Federal Reserve Bank in accordance with Regulation A of the Board of Governors of the Federal Reserve System.

-50-

Section 8.11 Participations

Each Bank may grant participations in a portion of its Notes, Letter of Credit participations and Commitments to any Eligible Lender, upon prior written notice to the Agent but without the consent of the Agent or the Borrower. No holder of any such participation, other than an Affiliate of such Bank, shall be entitled to require such Bank to take or omit to take any action hereunder, except that such Bank may agree with such participant that such Bank will not, without such participant’s consent, agree to any action described in paragraph (a) of Section 9.2. No Bank shall, as between the Borrower and such Bank, be relieved of any of its obligations hereunder as a result of any such granting of a participation. The Borrower hereby acknowledges and agrees that any participant described in this Section will, for purposes of Sections 2.16, 2.17 and 2.18 only, be considered to be a Bank hereunder (provided that such participant shall not be entitled to receive any more than the Bank selling such participation would have received had such sale not taken place).

Section 8.12 Limitation on Assignments and Participations.

Except as set forth in Sections 8.10 and 8.11, no Bank may assign any of its rights or obligations under, or grant any participation in, any Loan Document or Commitment.

Section 8.13 Disclosure of Information.

The Agent and the Banks 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 and its Subsidiaries to the Agent or the Banks pursuant to or in connection with the Loan Documents (the “Disclosed Information”). Notwithstanding the foregoing, the Agent and each Bank may disclose Disclosed Information (i) to the Agent or any other Bank; (ii) to any Affiliate of any Bank in connection with the transactions contemplated hereby, provided that such Affiliate has been informed of the confidential nature of such information; (iii) to legal counsel, accountants and other professional advisors to the Agent or such Bank; (iv) to any regulatory body having jurisdiction over any Bank or the Agent or any holding company thereof; (v) 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; (vi) to the extent such Disclosed Information (A) becomes publicly available other than as a result of a breach of this Agreement, (B) becomes available to the Agent or such Bank on a non-confidential basis from a source other than the Borrower or a Subsidiary, or (C) was available to the Agent or such Bank on a non-confidential basis prior to its disclosure to the Agent or such Bank by the Borrower or a Subsidiary; (vii) to the extent the Borrower or such Subsidiary shall have consented to such disclosure in writing; (viii) to the extent reasonably deemed necessary by the Agent or any Bank in the enforcement of the remedies of the Agent and the Banks provided under the Loan Documents; or (ix) 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

-51-

assignee or participant substantially the same obligations as are imposed on the Agent and the Banks under this Section 8.13.

Section 8.14 Titles.

The Persons identified on the title page as “Syndication Agent” and “Co-Lead Arrangers” shall have no right, power, obligation or liability under this Agreement or any other Loan Document on account of such identification other than those applicable to such Persons in their capacity (if any) as Banks. Each Bank acknowledges that it has not relied, and will not rely, on any Person so identified in deciding to enter into this Agreement or in taking or omitting any action hereunder.

ARTICLE IX
Miscellaneous

Section 9.1 No Waiver; Cumulative Remedies.

No failure or delay on the part of the Banks in exercising any right, power or remedy under the Loan Documents shall operate as a waiver thereof; nor shall any Bank’s acceptance of payments while any Default or Event of Default is outstanding operate as a waiver of such Default or Event of Default, or any right, power or remedy under the Loan Documents; nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy under the Loan Documents.

If and to the extent that the foregoing indemnity may be unenforceable for any reason, the Borrower hereby agrees to make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law. All obligations provided for in this Section shall survive any termination of this Agreement. Notwithstanding the foregoing, the Borrower shall not be obligated to indemnify any Indemnitee in respect of any Indemnified Liabilities arising as a result of the Issuing Bank’s failure to pay any Letter of Credit after the presentation to it of a request strictly complying with the terms and conditions of such Letter of Credit.

Section 9.6 Execution in Counterparts.

The following notification is provided to the Borrower pursuant to Section 326 of the USA Patriot Act of 2001, 31 U.S.C. Section 5318:

IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW ACCOUNT. To help the government of the United States of America fight the funding of terrorism and money laundering activities, Federal law requires all financial institutions to obtain, verify, and record information that identifies each Person that opens an account, including any deposit account, treasury management account, loan, other extension of credit, or other financial services product. Accordingly, when the Borrower opens an account, the Agent and the Banks will ask for the Borrower’s name, tax identification number, business address, and other information that will allow the Agent and the Banks to identify the Borrower. The Agent and the Banks may also ask to see the Borrower’s legal organizational documents or other identifying documents.

Section 9.16 Nonliability of Banks.

The relationship between the Borrower on the one hand and the Banks, the Issuing Bank and the Agent on the other hand shall be solely that of borrower and lender.

OPINION LETTER

[See Attached]

[Opinion of Gary Johnson]

May 14, 2004

To the Persons identified on
Schedule I hereto

Ladies and Gentlemen:

     I am the Vice President and General Counsel of Northern States Power Company (the “Borrower”) and have represented the Borrower in connection with the execution and delivery by the Borrower of the Credit Agreement dated as of May 14, 2004 (the “Credit Agreement”) by and between the Borrower, Wells Fargo Bank, National Association, as administrative agent (in such capacity, the “Agent”) and the financial institutions which are party thereto (the “Banks”). This opinion is delivered to you pursuant to Section 3.1(f) of the Credit Agreement. Capitalized terms used herein and not otherwise defined herein have the meanings assigned to such terms in the Credit Agreement.

     In rendering this opinion, I have examined the articles of incorporation and bylaws of the Borrower and its Subsidiaries, the Loan Documents, and have made such further investigation and examined such further documents as I deemed necessary to render an informed opinion on the matters hereinafter set forth. I have assumed: (a) the genuineness of the signatures on all documents and instruments (other than the signatures of the officers of Borrower), the authenticity of all documents submitted as originals, the conformity to originals of all documents submitted as photostatic or certified copies, and the accuracy and completeness of all corporate records made available to me by the Borrower; (b) that each of the parties (other than the Borrower) to the Loan Documents has the legal capacity, power and authority required for it to enter into the Loan Documents to which it is a party, and to perform its respective obligations thereunder; (c) that all such parties (except with respect to the Borrower) have received any corporate or other authorization required by any applicable charter, by-law, law or regulation; (d) the due execution and delivery of the Loan Documents by each of the parties thereto (other than the Borrower); and (e) that the Loan Documents constitute the legal, valid and binding obligations of the respective parties thereto, other than the Borrower.

     I am qualified to practice law in the State of Minnesota and do not purport to be expert on and express no opinion with respect to any laws other than the laws of the State of Minnesota.

     Based on such examination and investigation, it is my opinion that:

May 14, 2004
Page 7

     1. Each of the Borrower and its Subsidiaries is a corporation duly incorporated, validly existing and in good standing under the laws of the state of its incorporation, 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 or such Subsidiary from maintaining any material action in any such domestic 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 Change.

     2. Each of the Borrower and its Subsidiaries has all requisite corporate power and authority to conduct its business as described in the Borrower’s Annual Report on Form 10-K for the year ended December 31, 2003 filed with the SEC and to own its properties. The Borrower has all requisite corporate power and authority to execute, deliver, and perform its obligations under the Loan Documents.

     3. The Loan Documents have been duly and validly executed and delivered by the Borrower and constitute the Borrower’s legal, valid and binding obligations, enforceable in accordance with their respective terms (including in the case of the Notes against claims of usury), except (i) 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, (ii) to the extent that the indemnification provisions of the Loan Documents may be held to be unenforceable by applicable provisions of securities laws or public policy, and (iii) that I express no opinion as to the perfection or priority of any security interest purported to be created under the Loan Documents.

     4. The execution, delivery and performance by the Borrower of the Loan Documents, the borrowings from time to time thereunder and the consummation of the transactions therein contemplated, have been duly authorized by all necessary corporate action and do not and will not (i) require any consent or approval of the stockholders of the Borrower, or any authorization, consent, approval, order, filing, registration or qualification by any governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign, other than (A) those consents and approvals described in Schedule 4.2 to the Credit Agreement, which consents and approvals have been obtained and remain in full force and effect, (B) those filings, if any, required to perfect the security interests created under the Loan Documents and (C) any filings or approvals that may be required under state securities laws, (ii) violate any provision of any law, rule or regulation 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 material agreement, lease or instrument to which the Borrower is a party or by which it or its properties may be bound, or (iv) result in, or require, the creation or imposition of any Lien or other charge or encumbrance of any nature (other than the Liens created under the Loan Documents) upon or with respect to any of the properties now owned or hereafter acquired by the Borrower, except, in the case of clause (ii) or (iii), any such breach, violation or default which would not, individually or in the aggregate, result in a Material Adverse Change.

May 14, 2004
Page 8

     5. To the best of my knowledge, except as set forth in Schedule 4.7 to the Credit Agreement, there are no actions, suits or proceedings pending or overtly threatened against the Borrower or the properties of the Borrower before any court or governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign, which could reasonably be expected to effect a Material Adverse Change.

     6. The Minnesota Public Utilities Commission has issued its order (the “MPUC Order”) authorizing the incurrence by the Borrower the Advances under the Credit Agreement. The MPUC Order is in full force and effect on the date hereof.

     This opinion is rendered only with respect to the laws and the regulations which are in effect as of the date hereof. I assume no responsibility for updating this opinion to take into account any event, action, interpretation or change of law occurring subsequent to the date hereof that may affect the validity of any of the opinions expressed herein.

     The foregoing opinion is furnished solely for the benefit of the addressees hereof and their successors and assigns, in connection with the Loan Documents and the transactions contemplated thereby, and may not be relied upon by, and copies may not be delivered to, any other person or be used for any other purpose without my prior written consent. I hereby consent to reliance hereon by any future assignee of the Bank’s interests under the Credit Agreement as expressly permitted by Section 8.10 of the Credit Agreement; provided that such Bank has notified such assignee that this opinion speaks only as of the date hereof and to its addressees and that I have no responsibility or obligation to update this opinion, to consider its applicability or correctness to other than its addressees, or to take into account changes in law, facts or any other development of which I may later become aware.

Very truly yours,

[Opinion of Jones Day]

May 14, 2004

The Persons identified
on Schedule I hereto

Ladies and Gentlemen:

     We have acted as special counsel for Northern States Power Company, a Minnesota corporation (the “Borrower”), in connection with the Credit Agreement dated as of May 14, 2004 (the “Credit Agreement”) by and between the Borrower, Wells Fargo Bank, National Association, as administrative agent (in such capacity, the “Agent”), and the financial institutions which are party thereto (the “Banks”). This opinion is delivered to you pursuant to Section 3.1(f) of the Credit Agreement. Capitalized terms used herein and not otherwise defined herein have the meanings assigned to such terms in the Credit Agreement. With your permission, all assumptions and statements of reliance herein have been made without any independent investigation or verification on our part except to the extent, if any, otherwise expressly stated, and we express no opinion with respect to the subject matter or accuracy of the assumptions or items upon which we have relied.

     In connection with the opinions expressed herein, we have examined such documents, records and matters of law as we have deemed necessary for the purposes of this opinion. We have examined, among other documents, (i) a copy of the Credit Agreement and (ii) the form of Note attached as Exhibit B to the Credit Agreement (the “Note”). The Credit Agreement and the Notes issued thereunder are referred to herein collectively as the “Documents”. In all such examinations, we have assumed the legal capacity of all natural persons executing documents, the genuineness of all signatures, the authenticity of original and certified documents and the conformity to original or certified copies of all copies submitted to us as conformed or reproduction copies. As to various questions of fact relevant to the opinions expressed herein, we have relied upon, and assume the accuracy of, representations and warranties contained in the Documents and certificates and oral or written statements and other information of or from representatives of the Borrower and others and assume compliance on the part of the Borrower and each other party to the Documents with their covenants and agreements contained therein. With respect to the opinion expressed in paragraphs (a) and (b) below, our opinions are limited (x) to our actual knowledge of the specially regulated business activities and properties of the Borrower, based upon review of the Annual Report on Form 10-K for the fiscal year ended December 31, 2003 and the Form 10-Q for the quarter ended March 31, 2004, each as filed by the Borrower with the Securities and Exchange Commission, but without any additional investigation

May 14, 2004
Page 3

or verification on our part and (y) to our review of only those laws and regulations that, in our experience, are normally applicable to transactions of the type contemplated by the Credit Agreement.

Based upon the foregoing, and subject to the limitations, qualifications and assumptions set forth herein, we are of the opinion that:

     (a) Assuming that the execution and delivery of the Documents and the making of Advances thereunder by the Borrower have been, or will be as of the date of the making thereof, duly authorized and approved by an order of the Minnesota Public Utilities Commission, no approval, authorization, consent or order of any public board or body under the laws of the United States of America is legally required in connection with the execution and delivery of the Documents and the incurrence of the Obligations thereunder and the repayment thereof by the Borrower.

     (b) Based upon the assumption set forth in paragraph (a) above, the execution and delivery of the Documents by the Borrower and the performance by the Borrower of its obligations thereunder do not violate any present law, or present regulation of any governmental agency or authority, of the United States of America applicable to the Borrower or its property, including, without limitation, the Public Utility Holding Company Act of 1935, as amended (the “Holding Company Act”).

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

     (d) The Borrower is a “public utility” and a “subsidiary company” of a “holding company”, as such terms are defined in the Holding Company Act.

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

     1. To the extent it may be relevant to the opinions expressed herein, we have assumed that the parties to the Documents (other than the Borrower) have the power to enter into and perform such documents and to consummate the transactions contemplated thereby and that such documents have been duly authorized, executed and delivered by, and constitute legal, valid and binding obligations of, such parties.

     2. For purposes of our opinions above, we have assumed that (i) the Borrower is a corporation validly existing and in good standing in its jurisdiction of organization, (ii) the Borrower has all requisite power and authority, and has obtained all requisite corporate,

May 14, 2004
Page 4

shareholder, board, and third party authorizations, consents and approvals, (iii) except to the extent of our opinion in paragraph (a) above, the Borrower has obtained all requisite governmental authorizations, consents and approvals, and made all requisite filings and registrations, necessary to execute, deliver and perform the Documents, (iv) except to the extent of our opinion in paragraph (b) above, the execution, delivery and performance of the Documents by the Borrower will not violate or conflict with any law, rule, regulation, order, decree, judgment, instrument or agreement binding upon or applicable to the Borrower or its properties, and (v) the Documents to which the Borrower is a party have been duly executed and delivered by it.

     3. We express no opinion herein with respect to any law, rule or regulation as to tax or securities matters or as to any matters relating to ERISA.

The opinions expressed herein are limited to the federal laws of the United States.

     We express no opinion as to the compliance or noncompliance, or the effect of the compliance or noncompliance, of each of the addressees or any other person or entity with any state or federal laws or regulations applicable to each of them by reason of their status as or affiliation with a federally insured depository institution. Our opinions are limited to those expressly set forth herein, and we express no opinions by implication.

     The opinions expressed herein are solely for the benefit of the addressees hereof in connection with the transaction referred to herein and may not be relied on by such addressees for any other purpose or in any manner or for any purpose by any other person or entity; provided, however, that this opinion may be relied upon by any Additional Bank that becomes a Bank pursuant to the terms of the Credit Agreement to the extent that the addressees hereto may rely on it. This opinion speaks only as of the date hereof and to its addressees and we have no responsibility or obligation to update this opinion, to consider its applicability or correctness to other than its addressees, or to take into account changes in law, facts or any other development of which we may later become aware.
