WITNESSETH:

WHEREAS, the Borrower has requested the Lenders severally to commit to lend to the Borrower up to $250,000,000 on a revolving basis for general corporate purposes, including, without limitation, for commercial paper back-up;

WHEREAS, the Lenders are willing to make such loans, on the terms and conditions provided herein;

NOW, THEREFORE, the parties agree as follows:

ARTICLE I

DEFINITIONS

Section 1.01 Definitions.

(a) Terms Generally. The definitions ascribed to terms in this Agreement apply equally to both the singular and plural forms of such terms. Whenever the context may require, any pronoun shall be deemed to include the corresponding masculine, feminine and neuter forms. The words “include”, “includes” and “including” shall be interpreted as if followed by the phrase “without limitation”. The phrase “individually or in the aggregate” shall be deemed general in scope and not to refer to any specific Section or clause of this Agreement. All references herein to Articles, Sections, Exhibits and Schedules shall be deemed references to Articles and Sections of, and Exhibits and Schedules to, this Agreement unless the context shall otherwise require. The table of contents, headings and captions herein shall not be given effect in interpreting or construing the provisions of this Agreement. Except as otherwise expressly provided herein, all references to “dollars” or “$” shall be deemed references to the lawful money of the United States of America.

(b) Accounting Terms. Except as otherwise expressly provided herein, the term “consolidated” and all other terms of an accounting nature shall be interpreted and construed in accordance with GAAP, as in effect from time to time; provided, however, that, for purposes of determining compliance with any covenant set forth in Article VII, such terms shall be construed in accordance with GAAP as in effect on the date of this Agreement, applied on a basis consistent with the construction thereof applied in preparing the Borrower’s audited financial statements referred to in Section 5.01(k). If there shall occur a change in GAAP which but for the foregoing proviso would affect the computation used to determine

compliance with any covenant set forth in Article VII, the Borrower and the Lenders agree to negotiate in good faith in an effort to agree upon an amendment to this Agreement that will permit compliance with such covenant to be determined by reference to GAAP as so changed while affording the Lenders the protection intended to be afforded by such covenant prior to such change (it being understood, however, that such covenant shall remain in full force and effect in accordance with its existing terms unless and until such amendment shall become effective).

Section 4.02 Method and Time of Payments; Sharing among Lenders.

(a) All funds received by the Administrative Agent for the account of the Lenders in respect of payments made by the Borrower under, or from any other Person on account of, any Credit Document shall be distributed forthwith by the Administrative Agent among the Lenders, in like funds as received, ratably in proportion to their respective interests therein. Each payment of Commitment Fees and each reduction of the Total Commitment shall be apportioned among the Lenders in proportion to each Lender’s Pro Rata Share.

(b) All payments by the Borrower hereunder shall be made without setoff or counterclaim to the Administrative Agent, for its account or for the account of the Lender or Lenders entitled thereto, as the case may be, in dollars and in immediately available funds at the office of the Administrative Agent prior to 3:00 P.M., New York time, on the date when due.

(c) Whenever any payment from the Borrower shall be due on a day that is not a Business Day, the date of payment thereof shall be extended to the next succeeding Business Day. If the date for any payment of principal is extended by operation of law or otherwise, interest thereon shall be payable for such extended time.

(d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment from the Borrower is due that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, but shall not be obligated to, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent that the Borrower shall not have so made such payment, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate.

(e) If any Lender shall receive from the Borrower or any other Person any amount owing under any Credit Document (whether received pursuant to the exercise of any right of set-off, banker’s lien, realization upon any security held for or appropriated to such obligation or otherwise) other than in proportion to such Lender’s ratable share thereof, then such Lender shall purchase from each other Lender a participating interest in so much of the other Lenders’ Loans as shall be necessary in order that each Lender shall share such payment with each of the other Lenders in proportion to each Lender’s ratable share; provided that nothing herein contained shall obligate any Lender to apply any set-off, banker’s lien or collateral security first to the obligations of the Borrower hereunder if the Borrower is obligated to such Lender pursuant to other loans or notes. If any purchasing Lender shall be required to return any excess payment received

by it, such participation shall be rescinded and the purchase price restored to the extent of such return, but without interest.

Section 4.03 Compensation for Losses.

(a) If (i) the Borrower makes a prepayment, or a Conversion Date occurs, other than on the last day of the relevant Interest Period, (ii) the Borrower fails to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto, (iii) the Borrower revokes any Borrowing Request for Eurodollar Loans, (iv) Eurodollar Loans (or portions thereof) are converted into ABR Loans pursuant to Section 4.05 at any time other than at the end of an Interest Period or (v) Loans (or portions thereof) shall become or be declared to be due prior to the scheduled maturity thereof, then the Borrower shall pay to each Lender an amount that will compensate such Lender for any loss (other than lost profit) or premium or penalty incurred by such Lender as a result of such prepayment, conversion, declaration or revocation in respect of funds obtained for the purpose of making or maintaining such Lender’s Eurodollar Loans, or any portion thereof. Such compensation shall include an amount equal to the excess, if any, of (i) the amount of interest which would have accrued on the amount so paid or prepaid, or not borrowed or converted, for the period from the date of such payment or prepayment or conversion or failure to borrow to the last day of such Interest Period (or, in the case of a failure to borrow, the Interest Period that would have commenced on the date of such failure to borrow) in each case at the applicable rate of interest for such Eurodollar Loan provided for herein (excluding, however, any Applicable Margin included therein) over (ii) the amount of interest (as reasonably determined by such Lender) which would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the London interbank deposit market.

(b) In connection with a demand for payment pursuant to this Section 4.03, a Lender shall provide to the Borrower, with a copy to the Administrative Agent, a certificate, signed by an officer of such Lender, setting forth in reasonable detail the amount required to be paid by the Borrower to such Lender and the computations made by such Lender to determine such amount. In the absence of manifest error, such certificate shall be conclusive as to the amount so required to be paid.

Section 4.04 Withholding and Additional Costs.

(a) Withholding. (i) To the extent permitted by law, all payments under this Agreement and under the Revolving Credit Notes (including payments of principal and interest) shall be payable to each Lender free and clear of any and all present and future taxes, levies, imposts, duties, deductions, withholdings, fees, liabilities and similar charges other than Excluded Taxes (collectively, “Taxes”). If any Taxes are required to be withheld or deducted from any amount payable under this Agreement, then the amount payable under this Agreement shall be increased to the amount which, after deduction from such increased amount of all Taxes required to be withheld or deducted therefrom, will yield to such

Lender the amount stated to be payable under this Agreement. The Borrower shall also hold each Lender harmless and indemnify it for any stamp or other taxes with respect to the preparation, execution, delivery, recording, performance or enforcement of the Credit Documents (all of which shall be included within “Taxes”). If any of the Taxes specified in this Section 4.04(a) are paid by any Lender, the Borrower shall, upon demand of such Lender, promptly reimburse such Lender for such payments, together with any interest, penalties and expenses incurred in connection therewith. The Borrower shall deliver to the Administrative Agent certificates or other valid vouchers for all Taxes or other charges deducted from or paid with respect to payments made by the Borrower hereunder. Notwithstanding the foregoing, the Borrower shall be entitled, to the extent required to do so by law, to deduct or withhold (and shall not be required to make payments as otherwise required by this Section 4.04 on account of such deductions or withholdings) income or other similar taxes imposed by the United States of America from interest, fees or other amounts payable hereunder for the account of any Lender other than a Lender (A) that is a U.S. Person for U.S. federal income tax purposes or (B) that has the Prescribed Forms on file with the Borrower for the applicable year to the extent deduction or withholding of such taxes is not required as a result of such filing of such Prescribed Forms; provided that, if the Borrower shall so deduct or withhold any such taxes, the Borrower shall provide a statement to the Administrative Agent and such Lender, setting forth the amount of such taxes so deducted or withheld, the applicable rate and any other information or documentation which such Lender may reasonably request for assisting such Lender to obtain any allowable credits or deductions for the taxes so deducted or withheld in the jurisdiction or jurisdictions in which such Lender is subject to tax.

(ii) Each Lender that is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) agrees to deliver to the Borrower and the Administrative Agent on or prior to the Effective Date, or in the case of a Lender that is an assignee or transferee of an interest under this Agreement pursuant to Section 10.03 (unless the respective Lender was already a Lender hereunder immediately prior to such assignment or transfer), on the date of such assignment or transfer to such Lender, (i) if the Lender is a “bank” within the meaning of Section 881(c)(3)(A) of the Code, two accurate and complete original signed copies of Internal Revenue Service Form W-8BEN or Form W-8ECI (or successor forms) certifying such Lender’s entitlement to a complete exemption from United States withholding tax with respect to payments to be made under this Agreement and under any Revolving Credit Note, or (ii) if the Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, either Internal Revenue Service Form W-8BEN or Form W-8ECI as set forth in clause (i) above, or (x) a certificate in substantially the form of Schedule II (any such certificate, a “Schedule II Certificate”) and (y) two accurate and complete original signed copies of Internal Revenue Service Form W-8BEN (or successor form) certifying such Lender’s entitlement to an exemption from United States withholding tax with respect to payments of interest to be made under this Agreement and under any Revolving Credit Note. In addition, each Lender agrees that it will deliver upon the Borrower’s request updated versions of the foregoing, as applicable, whenever the

previous certification has become obsolete or inaccurate in any material respect, together with such other forms as may be required in order to confirm or establish the entitlement of such Lender to a continued exemption from or reduction in United States withholding tax with respect to payments under this Agreement and any Revolving Credit Note. Notwithstanding anything to the contrary contained in Section 4.04(a), but subject to the immediately succeeding sentence, (x) the Borrower shall be entitled, to the extent it is required to do so by law, to deduct or withhold Taxes imposed by the United States (or any political subdivision or taxing authority thereof or therein) from interest, fees or other amounts payable hereunder for the account of any Lender which is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) for U.S. federal income tax purposes to the extent that such Lender has not provided to the Borrower U.S. Internal Revenue Service Forms that establish a complete exemption from such deduction or withholding and (y) the Borrower shall not be obligated pursuant to Section 4.04(a) hereof to gross-up payments to be made to a Lender in respect of Taxes imposed by the United States if (I) such Lender has not provided to the Borrower the Internal Revenue Service Forms required to be provided to the Borrower pursuant to this Section 4.04(b) or (II) in the case of a payment, other than interest, to a Lender described in clause (ii) above, to the extent that such Forms do not establish a complete exemption from withholding of such Taxes. Notwithstanding anything to the contrary contained in the preceding sentence or elsewhere in this Section 4.04, the Borrower agrees to pay additional amounts and to indemnify each Lender in the manner set forth in Section 4.04(a) (without regard to the identity of the jurisdiction requiring the deduction or withholding) in respect of any amounts deducted or withheld by it as described in the immediately preceding sentence as a result of any changes after the Effective Date in any applicable law, treaty, governmental rule, regulation, guideline or order, or in the interpretation thereof, relating to the deducting or withholding of Taxes.

(b) Additional Costs. Subject to Sections 4.04(c), (d) and (e):

(i) Without duplication of any amounts payable described in Section 3.03(c) or 4.03 (a), if after the date hereof, any change in any law or regulation or in the interpretation thereof by any court or administrative or Governmental Authority charged with the administration thereof or the enactment of any law or regulation shall either (1) impose, modify or deem applicable any reserve, special deposit or similar requirement against any Lender’s Commitment or Loans or (2) impose on any Lender (or such Lender’s Applicable Lending Office) any other condition regarding this Agreement, its Commitment or the Loans and the result of any event referred to in clause (1) or (2) shall be to increase the cost to such Lender (or such Lender’s Applicable Lending Office) of maintaining its Commitment or any Eurodollar Loans made by such Lender (which increase in cost shall be calculated in accordance with such Lender’s reasonable averaging and attribution methods) by an amount which such Lender deems to be material, then, upon demand by such Lender, the Borrower shall pay to such Lender, on demand, an amount equal to such increase in cost; and

(ii) Without duplication of any amounts payable described in Section 3.03(c) or 4.03(a), if any Lender shall have determined that the adoption of any applicable law, rule, regulation or guideline regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, (including any such adoption or change made prior to the date hereof but not effective until after the date hereof) or compliance by such Lender (or such Lender’s Applicable Lending Office) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on capital for such Lender (or such Lender’s Applicable Lending Office) or any corporation controlling such Lender as a consequence of its obligations under this Agreement to a level below that which such Lender (or such Lender’s Applicable Lending Office) or such corporation could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s (or such Lender’s Applicable Lending Office) or such corporation’s policies with respect to capital adequacy), then from time to time, upon demand by such Lender, then the Borrower shall pay to such Lender, on demand, such additional amount or amounts as will compensate such Lender (or such Lender’s Applicable Lending Office) or such corporation for such reduction.

(c) Lending Office Designations. Before making any demand for payment pursuant to this Section 4.04, each Lender shall, if possible, designate a different Applicable Lending Office if such designation will avoid the need for giving such notice and will not, in the judgment of such Lender, be otherwise disadvantageous to such Lender.

(d) Certificate, Etc. In connection with any demand for payment pursuant to this Section 4.04, a Lender shall provide to the Borrower, with a copy to the Administrative Agent, a certificate, signed by an officer of such Lender, setting forth in reasonable detail the basis for such demand, the amount required to be paid by the Borrower to such Lender the computations made by such Lender to determine such amount.

(e) Limitations. The Borrower shall not be obligated to compensate a Lender for any amount under Section 4.04(b) (i) and (ii) arising or occurring more than 90 days prior to the date on which an office of such Lender primarily responsible for the administration of this Agreement obtains actual knowledge that such Lender is entitled to such compensation.

Section 4.05 Funding Impracticable.

If at any time any Lender shall have determined in good faith (which determination shall be conclusive) that the making or maintenance of all or any part of such Lender’s Eurodollar Loans has been made impracticable or unlawful

because of compliance by such Lender in good faith with any law or guideline or interpretation or administration thereof by any Governmental Authority charged with the interpretation or administration thereof or with any request or directive of such body (whether or not having the effect of law) or because U.S. dollar deposits in the amount and requested maturity of such Eurodollar Loans are not available to such Lender in the London Eurodollar interbank market, then the Administrative Agent, upon notification to it of such determination by such Lender, shall forthwith advise the other Lenders and the Borrower thereof. Upon such date as shall be specified in such notice and until such time as the Administrative Agent, upon notification to it by such Lender, shall notify the Borrower and the other Lenders that the circumstances specified by it in such notice no longer apply, (i) notwithstanding any other provision of this Agreement, such Eurodollar Loans shall, automatically and without requirement of further notice, or any payment pursuant to Section 4.03 or 4.04, by the Borrower, be converted to ABR Loans, and (ii) the obligation of such Lender to make or continue Eurodollar Loans shall be suspended, and, if the Borrower shall request in a Borrowing Request or Conversion Request that the Lenders make a Eurodollar Loan, the Loan requested to be made by such Lender shall instead be made as an ABR Loan.

Section 4.06 Expenses; Indemnity.

(a) The Borrower agrees to pay all reasonable out-of-pocket expenses incurred by the Administrative Agent or any Lender (including reasonable fees and disbursements of counsel) in connection with the enforcement of, and the protection of their respective rights under, any provision of any Credit Document or any amendment or supplement to this Agreement.

(b) The Borrower agrees to indemnify the Administrative Agent, BNY Capital Markets, Inc. and each of the Lenders and their respective directors, officers, employees and agents (each, an “Indemnitee”) against, and to hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including counsel fees and expenses, incurred by or asserted against any Indemnitee arising out of, in any way connected with, or as a result of (i) the execution or delivery of any Credit Document or any agreement or instrument contemplated by any Credit Document, the performance by the parties thereto of their respective obligations under any Credit Document or the consummation of the transactions contemplated by any Credit Document, (ii) the use of the proceeds of the Loans or (iii) any claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not 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 are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee.

(c) All amounts due under this Section 4.06 shall be payable in immediately available funds upon written demand therefor.

Section 4.07 Survival.

The provisions of Sections 4.03, 4.04, 4.06 and 9.06, shall remain operative and in full force and effect regardless of the expiration of the term of this Agreement, the consummation of the transactions contemplated hereby, the repayment of any of the Loans, the reduction or termination of any Commitments, the invalidity or unenforceability of any term or provision of any Credit Document, or any investigation made by or on behalf of the Lenders.

Section 4.08 Substitution of a Lender.

Notwithstanding anything to the contrary contained herein, if any Lender shall request compensation pursuant to Section 4.04(b)(i) and (ii) then, in each case, the Borrower may require that such Lender transfer all of its right, title and interest under this Agreement and such Lender’s Revolving Credit Notes to one or more of the other Lenders or any other lender identified by the Borrower and reasonably acceptable to the Administrative Agent (a “Substitute Lender”) which is willing to assume all of the obligations of such Lender, for consideration equal to the outstanding principal amount of such Lender’s Loans, together with interest thereon to the date of such transfer and all other amounts payable under the Credit Documents to such Lender on or prior to the date of such transfer (including, without limitation, any fees accrued hereunder and any amounts which would be payable under Section 4.03 as if all of such Lender’s Loans were being prepaid in full on such date). Subject to the execution and delivery of new notes, an Assignment and Acceptance, and such other documents as such Lender may reasonably require, such Substitute Lender shall be a “Lender” for all purposes hereunder. Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements of the Borrower contained in Sections 4.04 and 4.06 (without duplication of any payments made to such Lender by the Borrower or the Substitute Lender) shall survive for the benefit of any Lender replaced under this Section 4.08 with respect to the time prior to such replacement.

(i) Title to Properties.

with GAAP, and (b) those levied or imposed on Subsidiaries other than Significant Subsidiaries the nonpayment of which would not, in the aggregate, have a Material Adverse Effect. To the best knowledge of the Borrower, there is no proposed tax assessment against the Borrower or any of its Subsidiaries which would, if the assessment were made, have a Material Adverse Effect.

(k) Financial Condition.

The audited consolidated balance sheet of the Borrower as of December 31, 2003 and the related consolidated statements of income, changes in shareholders’ equity and cash flows for the period then ended, copies of which have been furnished to the Administrative Agent and the Lenders, fairly present the consolidated financial condition of the Borrower and its consolidated Subsidiaries as of, and the results of its operations and cash flows for, the period then ended, applied on a consistent basis.

(l) Environmental Matters.

(iii) None of the Borrower, any of its Subsidiaries or any of their present Property or operations is subject to any outstanding written order from or agreement with any Governmental Authority or other Person, nor subject to any judicial or docketed administrative proceeding, respecting any Environmental Law, Environmental Claim or Hazardous Material which would have a Material Adverse Effect.

(iv) There are no conditions or circumstances which may give rise to any Environmental Claim arising from the operations of the Borrower or its Subsidiaries which would have a Material Adverse Effect.

applicable Environmental Laws or (y) that are leaking or disposing of Hazardous Materials offsite and (ii) the Borrower and its Subsidiaries have notified all of their employees of the existence, if any, of any health hazard arising from the conditions of their employment and have met all notification requirements under Title III of CERCLA or any other Environmental Law.

(n) Labor Relations.

(p) Full Disclosure. None of the representations or warranties made by the Borrower in this Agreement as of the date of such representations and warranties, and none of the statements contained in any certificate furnished by or on behalf of the Borrower in connection with this Agreement contains any untrue statement of a material fact or omits any material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances under which they are made, not misleading.

(q) Compliance with Applicable Laws. Neither the Borrower nor any Subsidiary is in default with respect to any judgment, order, writ, injunction, decree or decision of any Governmental Authority which default would have a Material Adverse Effect. The Borrower and each Subsidiary is complying in all material respects with all applicable statutes and regulations, including ERISA and applicable occupational, safety and health and other labor laws, of all Governmental Authorities, a violation of which would have a Material Adverse Effect.

(r) Ranking. The Obligations of the Borrower to the Lenders to be undertaken under the Credit Documents will rank senior to or pari passu with other Unsecured Debt of the Borrower.

Section 5.02 Survival.

All representations and warranties made by the Borrower in this Agreement, and in the certificates or other instruments prepared or delivered in connection with or pursuant to this Agreement, shall (i) be considered to have been relied upon by the Lenders, (ii) survive the making of Loans regardless of any investigation made by, or on behalf of, the Lenders, and (iii) continue in full force and effect as long as the Commitments have not been terminated and, thereafter, so long as any Loan, fee or other amount payable hereunder remains unpaid.

ARTICLE X

EVIDENCE OF LOANS; TRANSFERS

Section 10.01 Evidence of Loans; Revolving Credit Notes.

The Borrower’s obligation to repay the Loans shall be evidenced by Revolving Credit Notes, one such payable to the order of each Lender. The Revolving Credit Note of each Lender shall (i) be in the principal amount of such Lender’s Commitment, (ii) be dated the Effective Date and (iii) be stated to mature on the Termination Date and bear interest from its

date until maturity on the principal balance (from time to time outstanding thereunder) payable at the rates and in the manner provided herein. Each Lender is authorized to indicate upon the grid attached to its Revolving Credit Note all Loans made by it pursuant to this Agreement, interest elections and payments of principal and interest thereon. Such notations shall be presumptive, absent manifest error, as to the aggregate unpaid principal amount of all Loans made by such Lender, and interest due thereon, but the failure by any Lender to make such notations or the inaccuracy or incompleteness of any such notations shall not affect the obligations of the Borrower hereunder or under the Revolving Credit Notes.

Section 10.02 Participations.

Any Lender may at any time grant to one or more financial institutions (each a “Participant”) participating interests in its Commitment or any or all of its Loans. In the event of any such grant by a Lender of a participating interest to a Participant, whether or not upon notice to the Borrower and the Administrative Agent, such Lender shall remain responsible for the performance of its obligations hereunder, and, except to the extent such participating interest has been granted pursuant to Section 4.02(e), the Borrower and the Administrative Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement pursuant to which any Lender may grant such a participating interest shall provide that such Lender shall retain the sole right and responsibility to enforce the obligations of the Borrower hereunder including the right to approve any amendment, modification or waiver of any provision of this Agreement; provided, that such participation agreement may provide that such Lender will not agree to any modification, amendment or waiver of this Agreement described in clauses (i) through (vi), inclusive, of Section 11.06 without the consent of the Participant.

Section 10.03 Assignments.

(a) Any Lender may at any time assign to one or more financial institutions (each an “Assignee”) all, or a proportionate part of all, of its rights and obligations under this Agreement, and such Assignee shall assume such rights and obligations, pursuant to an instrument, in substantially the form of Exhibit E (an “Assignment and Acceptance”), executed by such Assignee and such transferring Lender, with (and subject to) the signed consent of the Borrower and the Administrative Agent (which consents shall not be unreasonably withheld); provided, that the foregoing consent requirement shall not be applicable in the case of an assignment or other transfer by any Lender to an affiliate of such Lender, to another Lender or to a Federal Reserve Bank provided further, that any consent of the Borrower otherwise required under this Section shall not be required if an Event of Default has occurred and is continuing. Upon execution and delivery of an Assignment and Acceptance and payment by such Assignee to such transferring Lender of an amount equal to the purchase price agreed between such transferring Lender and such Assignee and payment by the transferring

Lender or the Assignee of an assignment fee of $3,500 to the Administrative Agent, such Assignee shall be a Lender party to this Agreement and shall have all the rights and obligations of a Lender with a Commitment as set forth in such Assignment and Acceptance, and the transferring Lender shall be released from its obligations hereunder to a corresponding extent, and no further consent or action by any party shall be required.

(b) No Assignee of any transferring Lender’s rights shall be entitled to receive any greater payment under Section 4.03 or 4.04 than such Lender would have been entitled to receive with respect to the rights transferred, unless such transfer is made with the Borrower’s prior written consent or by reason of the provisions of Section 4.04(c) requiring such transferring Lender to designate a different Applicable Lending Office under certain circumstances or at a time when the circumstances giving rise to such payment did not exist.

Section 10.04 Certain Pledges.

Notwithstanding any other provision in this Agreement, any Lender may at any time create a security interest in, or pledge, all or any portion of its rights under this Agreement and any Revolving Credit Note held by it in favor of any Federal Reserve Bank in accordance with Federal Reserve Board Regulation A (or any successor provision) or U.S. Treasury Regulation 31 C.F.R. § 203.14 (or any successor provision), and such Federal Reserve Bank may enforce such pledge or security interest in any manner permitted under applicable law.
