             THIS CREDIT AGREEMENT (this “Agreement”) is made and entered into as of April 19, 2002, by and among ALLEGHENY ENERGY SUPPLY COMPANY, LLC, a Delaware limited liability company (the “Borrower”), the several banks and other financial institutions from time to time party hereto, BANK ONE, NA, as the issuer of Letters of Credit, and CITIBANK, N.A. (“Citibank”, in its capacity as Administrative Agent for the Lenders, the “Administrative Agent”).

W I T N E S S E T H:

             WHEREAS, the Borrower has requested that the Lenders establish a 3-year unsecured revolving credit facility in an amount up to $400,000,000 in favor of the Borrower, all of which may be used for general corporate purposes, including commercial paper backup, and the issuance of Letters of Credit.

             WHEREAS, subject to the terms and conditions of this Agreement, the Lenders severally, to the extent of their respective Commitments as defined herein, are willing to establish the requested revolving credit facility in favor of the Borrower.

             NOW, THEREFORE, in consideration of the premises and the mutual covenants herein contained, the Borrower, the Lenders, the Issuing Bank and the Administrative Agent agree as follows:

             In addition to the other terms defined herein, the following terms used herein shall have the meanings herein specified (to be equally applicable to both the singular and plural forms of the terms defined):

             “Adjusted LIBO Rate” shall mean, with respect to each Interest Period for a Eurodollar Borrowing, the rate per annum obtained by dividing (i) LIBOR for such Interest Period by (ii) a percentage equal to 1.00 minus the Eurodollar Reserve Percentage.

             “Administrative Questionnaire” shall mean, with respect to each Lender, an administrative questionnaire in the form prepared by the Administrative Agent and submitted to the Administrative Agent duly completed by such Lender.

             “Affiliate” shall mean, as to any Person, any other Person that directly, or indirectly through one or more intermediaries, Controls, is Controlled by, or is under common Control with, such Person. For purposes of this definition, “control” shall mean the power, directly or indirectly, either to (i) vote 5% or more of securities having ordinary voting power for the

2

election of directors (or persons performing similar functions) of a Person or (ii) direct or cause the direction of the management and policies of a Person, whether through the ability to exercise voting power, by contract or otherwise. The terms “controlling”, “controlled by”, and “under common control with” have meanings correlative thereto.

             “Aggregate Commitments” shall mean, collectively, all Commitments of all Lenders at any time outstanding. 

             “Applicable Lending Office” shall mean, for each Lender and for each Type of Loan, the “Lending Office” of such Lender (or an Affiliate of such Lender) designated for such Type of Loan in the Administrative Questionnaire submitted by such Lender or such other office of such Lender (or an Affiliate of such Lender) as such Lender may from time to time specify to the Administrative Agent and the Borrower as the office by which its Loans of such Type are to be made and maintained.

             “Applicable Margin” means, with respect to any Base Rate Loan and any Eurodollar Loan, at all times during which any Applicable Rating Level set forth below is in effect, the rate per annum (except as provided below) for such Loan set forth below next to such Applicable Rating Level.

	  	 	5	 	1.500%	 	1.000%	 
	  	 	6	 	1.625%	 	1.250%	 

A change in the Applicable Margin resulting from a change in the Applicable Rating Level shall become effective upon the date of announcement of a change in the Moody’s rating or the S&P rating that results in a change in the Applicable Rating Level. The Applicable Margin shall be calculated on a 360-day basis.

3

             “Applicable Rating Level” at any time shall be determined in accordance with the then applicable S&P rating and the then applicable Moody’s rating assigned to the senior unsecured long-term debt of the Borrower without third-party credit enhancement (the “Reference Ratings”) as follows:

	S&P Rating/Moody’s Rating		Applicable Rating Level	
	
		
	
	S&P Rating of at least A- and Moody’s Rating

   BBB and Moody’s Rating of 
   at least Baa2	 	3

	S&P Rating of at least 
   BB+ and Moody’s Rating of at 
   least Ba1	 	5	 
	Reference Ratings lower than

Each change in Citibank’s prime lending rate shall be effective from and including the date such change is publicly announced as being effective.

             “Withdrawal Liability” shall mean liability to a Multiemployer Plan in an amount in excess of $25,000,000 as a result of a complete or partial withdrawal from such Multiemployer Plan, as such terms are defined in Part I of Subtitle E of Title IV of ERISA.

SECTION 1.2. Classifications of Loans and Borrowings. 

             For purposes of this Agreement, Borrowings also may be classified and referred to by Type (e.g. “Eurodollar Borrowing”).

SECTION 1.3. Accounting Terms and Determination. 

             Unless otherwise defined or specified herein, all accounting terms used herein shall be interpreted, all accounting determinations hereunder shall be
made, and all financial statements required to be delivered hereunder shall be prepared, in accordance with GAAP as in effect from time to time, applied on a basis consistent with the most recent audited consolidated financial statement of the Borrower delivered pursuant to Section 5.1(a); provided, that if the
Borrower notifies the Administrative Agent that it wishes to amend any covenant in Article VI to eliminate the effect of any change in GAAP on the operation of such covenant (or if the Administrative Agent notifies the Borrower that the Required Lenders wish to amend Article VI for such purpose), then the Borrower’s compliance with such covenant shall be
determined on the basis of GAAP in effect immediately before the relevant change in GAAP became effective, until either such notice is withdrawn or such covenant is amended in a manner satisfactory to the Borrower and the Required Lenders.

SECTION 1.4. Terms Generally.

specified date, the word “from” means “from and including” and the word “to” means “to but excluding”. Unless the context requires otherwise (i) any definition of or reference to any agreement, instrument or other document herein shall be construed as referring to such agreement, instrument or
other document as it was originally executed or as it

Exhibits and Schedules to this Agreement and (v) all references to a specific time shall be construed to refer to the time in the city and state of the Administrative Agent’s principal office, unless otherwise indicated. 

ARTICLE II
AMOUNT AND TERMS OF THE COMMITMENTS

SECTION 2.1. General Description of Facility.

             Subject to and upon the terms and conditions herein set forth, (i) the Lenders hereby establish in favor of the Borrower a revolving credit facility pursuant to which the Lenders severally agree (to the extent of each Lender’s Commitment) to make Loans to the Borrower in an amount not to exceed the aggregate Commitments in accordance with Section 2.2, (ii) the Issuing Bank agrees to issue Letters of Credit in accordance with Section 2.20, and (iii) each Lender agrees to purchase a participation interest in the Letters of Credit pursuant to the terms and conditions hereof; provided, that in no event shall the aggregate principal amount of all outstanding Loans and the LC Exposure exceed at any time the Aggregate Commitments in effect at such time.

SECTION 2.2. Loans. 

             Subject to the terms and conditions set forth herein, each Lender severally agrees (to the extent of its Commitment) to make Loans to the Borrower ratably in proportion to its Pro Rata Share in an aggregate principal amount not exceeding such Lender’s Commitment. The Borrower shall be entitled to borrow, prepay and reborrow Loans in accordance with the terms and conditions of this Agreement; provided, that the Borrower may not borrow or reborrow if a Default or Event of Default has occurred and is continuing.

SECTION 2.3. Procedure for Borrowings. 

             The Borrower shall give the Administrative Agent written notice (or telephonic notice promptly confirmed in writing) of each Borrowing substantially in the form of Exhibit 2.3 attached hereto (a “Notice of Borrowing”) (x) by 11:00 a.m. on the requested date of a Base Rate Borrowing and (y) by 11:00 a.m. three Business Days prior to the requested date of a Eurodollar Borrowing. The Notice of Borrowing shall be irrevocable and shall specify: (i) the aggregate principal amount of such Borrowing, (ii) the date of such Borrowing (which shall be a Business Day), (iii) the Type of Loan comprising such Borrowing and (iv) in the case of a Eurodollar Borrowing, the duration of the initial Interest Period applicable thereto (subject to the provisions of the definition of Interest Period). Each Borrowing shall consist entirely of Base Rate Loans or
Eurodollar Loans, as the Borrower may request, until the Borrower elects a different interest rate option under Section 2.5. The aggregate principal amount of each Eurodollar Borrowing shall be 

20

not less than $5,000,000 or a larger multiple of $1,000,000, and the aggregate principal amount of each Base Rate Borrowing shall not be less than $1,000,000 or a larger multiple of $100,000. Promptly following the receipt of the Notice of Borrowing in accordance herewith, the Administrative Agent shall advise each Lender of the details thereof and the amount of such Lender’s Loan to be made as part of the requested Borrowing.

SECTION 2.4. Funding of Borrowings.

             Each Lender will make available the Loan to be made by it hereunder on the proposed date thereof by wire transfer in immediately available funds by 11:00 a.m. in the case of a Eurodollar Loan, or by 1:00 p.m. in the case of a Base Rate Loan, to the Administrative Agent at the Payment Office. If by (A) 5:00 p.m. on the Business Day preceding such proposed date in the case of a Eurodollar Loan or (B) 11:00 a.m. on such proposed date in the case of a Base Rate Loan, the Borrower has met all of the conditions precedent, set forth in Sections 3.1 and 3.2 of the Agreement, the Administrative Agent will make such Loans available to the Borrower by initiating a wire transfer by 12:00 noon in the case of a Eurodollar Loan, or by 2:00 p.m. in the case of a Base Rate Loan, on such proposed date to an account designated by the Borrower to the Administrative Agent.

             (a)   Unless the Administrative Agent shall have been notified by any Lender prior to (A) 5:00 p.m. one Business Day prior to the date of a Eurodollar Borrowing or (B) 12:00 noon on the date of a Base Rate Borrowing in which such Lender is participating that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such amount available to the Administrative Agent on such date, and the Administrative Agent, in reliance on such assumption, may make available to the Borrower on such date a corresponding amount. If such corresponding amount is not in fact made available to the Administrative Agent by such Lender on the date of such Borrowing, the Administrative Agent shall be entitled to recover such corresponding amount on demand from such
Lender together with interest at the Federal Funds Rate for up to two days and thereafter at the rate specified for such Borrowing. If such Lender does not pay such corresponding amount forthwith upon the Administrative Agent’s demand therefor, the Administrative Agent shall promptly notify the Borrower, and the Borrower shall immediately pay such corresponding amount to the Administrative Agent together with interest at the rate specified for such Borrowing. Nothing in this subsection shall be deemed to relieve any Lender from its obligation to fund its Pro Rata Share of any Borrowing hereunder or to prejudice any rights which the Borrower may have against any Lender as a result of any default by such Lender hereunder.

             (b)   All Borrowings shall be made by the Lenders on the basis of their respective Pro Rata Shares. No Lender shall be responsible for any default by any other Lender in its obligations hereunder, and each Lender shall be obligated to make its Loans provided to be made by it hereunder, regardless of the failure of any other Lender to make its Loans hereunder.

SECTION 2.5. Interest Elections.

             (a)   Each Borrowing initially shall be of the Type specified in the Notice of Borrowing, and in the case of a Eurodollar Borrowing, shall have an initial Interest Period as 

21

specified in such Notice of Borrowing. Thereafter, the Borrower may elect to convert such Borrowing into a different Type or to continue such Borrowing, and in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. At no time shall the total number of Eurodollar Borrowings outstanding exceed four. 

             (b)   To make an election pursuant to this Section, the Borrower shall give the Administrative Agent prior written notice (or telephonic notice promptly confirmed in writing) of each Borrowing (a “Notice of Conversion/Continuation”) that is to be converted or continued, as the case may be, (x) by 1:00 p.m. on the requested date of a conversion into a Base Rate Borrowing and (y) by 11:00 a.m. three Business Days prior to a continuation of or conversion into a Eurodollar Borrowing. Each such Notice of Conversion/Continuation shall be irrevocable and shall specify (i) the Borrowing to which such Notice of Continuation/Conversion applies and if different options are being elected with respect to different portions thereof, the portions thereof that are to be allocated to each resulting Borrowing (in which case the information to be
specified pursuant to clauses (iii) and (iv) shall be specified for each resulting Borrowing); (ii) the effective date of the election made pursuant to such Notice of Continuation/Conversion, which shall be a Business Day, (iii) whether the resulting Borrowing is to be a Base Rate Borrowing or a Eurodollar Borrowing; and (iv) if the resulting Borrowing is to be a Eurodollar Borrowing, the Interest Period applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of “Interest Period”. If any such Notice of Continuation/Conversion requests a Eurodollar Borrowing but does not specify an Interest Period, the Borrower shall be deemed to have selected an Interest Period of one month. The principal amount of any resulting Borrowing shall satisfy the minimum borrowing amount for Eurodollar Borrowings and Base Rate Borrowings set forth in Section 2.3.

             (c)   If, on the expiration of any Interest Period in respect of any Eurodollar Borrowing, the Borrower shall have failed to deliver a Notice of Conversion/Continuation, then, unless such Borrowing is repaid as provided herein, the Borrower shall be deemed to have elected to convert such Borrowing to a Base Rate Borrowing. No Borrowing may be converted into, or continued as, a Eurodollar Borrowing if a Default or an Event of Default has occurred and is continuing, unless the Administrative Agent and each of the Lenders shall have otherwise consented in writing. No conversion of any Eurodollar Loans shall be permitted except on the last day of the Interest Period in respect thereof. 

             (d)   Upon receipt of any Notice of Conversion/Continuation, the Administrative Agent shall promptly notify each Lender of the details thereof and of such Lender’s Pro Rata Share of each resulting Borrowing.

SECTION 2.6. Changes of Commitments.

             (a)   All Commitments hereunder shall terminate on the Termination Date.

             (b)   Upon at least three Business Days’ prior written notice (or telephonic notice promptly confirmed in writing) to the Administrative Agent (which notice shall be irrevocable), the 

22

Borrower may reduce the unused portion of the Commitments in part or terminate such Commitments in whole; provided, that (i) any partial reduction shall apply to reduce proportionately and permanently the Commitment of each Lender and (ii) any partial reduction pursuant to this Section 2.6 shall be in an amount of at least $5,000,000 and any larger multiple of $1,000,000. Any such reduction in the Aggregate Commitments shall result in a proportional reduction in the LC Commitment. Once terminated, a Commitment may not be reinstated.

             (c)   Increase of Commitments.

             (i)   Requests for Increase by Company. The Borrower may, for a period of 45 days after the date hereof, by notice to the Administrative Agent, propose that the aggregate amount of the Commitments be increased (each such proposed increase being a “Commitment Increase”), effective as of a date (the “Commitment Increase Date”) that shall be specified in such notice and that shall be prior to the Approved Termination Date; provided that 

             (A)   the proposed Commitment Increase in respect of the Commitment of either (i) any Increasing Lender or (ii) any Assuming Lender for each Commitment Increase Date shall be in the aggregate amount of $10,000,000 or a multiple of $1,000,000 in excess thereof, provided that the minimum amount of the Commitment of any Assuming Lender shall be $15,000,000,

             (B)   in no event shall the aggregate amount of the Commitments hereunder, and under the 364-Day Credit Agreement, dated as of the date hereof, among the Borrower, Allegheny Generating Company, the Lenders named therein, Citibank, as administrative agent, and Bank One, as issuer of letters of credit, at any time exceed $1,000,000,000,

             (C)   no
      Default shall have occurred and be continuing on such Commitment Increase
      Date or shall result from the proposed Commitment Increase, and

             (D)   the representations and warranties contained in Article IV shall be correct on and as of the Commitment Increase Date as if made on and as of such date.

The Administrative Agent shall notify the Lenders of a proposed Commitment Increase promptly upon its receipt of any notice from the Borrower with respect to such proposed Commitment Increase. It shall be in each Lender’s sole discretion whether to increase its Commitment hereunder in connection with any proposed Commitment Increase. No later than ten Business Days (or such longer period as the Borrower and the Administrative Agent shall agree) after its receipt of the Borrower’s notice proposing a Commitment Increase, each Lender that is willing to increase its Commitment hereunder (each such Lender being an “Increasing Lender”) shall deliver to the Administrative Agent a notice in which such Lender shall set forth the maximum increase in its Commitment to which such Lender is willing to agree, and the Administrative Agent shall promptly provide to
the Company a copy of such Increasing Lender’s notice. 

23

             (ii)   Acceptance of Commitment Increase by the Borrower. If agreement is reached prior to the relevant Commitment Increase Date with any Increasing Lenders and Assuming Lenders, if any, as to a Commitment Increase (the amount of which may be less than (subject to the limitation set forth in clause (i)(A) of this Section 2.6(c)) but not greater than that amount specified in the applicable notice from the Borrower), the Borrower shall deliver, no later than three Business Days prior to such Commitment Increase Date, a notice thereof in reasonable detail to the Administrative Agent (and the Administrative Agent shall give notice thereof to the Lenders, including any Assuming Lenders). The Assuming Lenders, if any, shall become Lenders hereunder as of such Commitment Increase Date, and the Commitments of any Increasing Lenders and such Assuming Lenders
shall be increased as of such Commitment Increase Date; provided that:

             (x)   the Administrative Agent shall have received on or prior to 9:00 a.m., New York City time, on such Commitment Increase Date a certificate of a duly authorized officer of the Borrower stating that each of the applicable conditions to such Commitment Increase set forth in this Section 2.6(c) has been satisfied;

             (y)   with respect to each Assuming Lender, the Administrative Agent shall have received, on or prior to 9:00 a.m., New York City time, on such Commitment Increase Date, an appropriate Assumption Agreement in substantially the form of Exhibit E, duly executed by such Assuming Lender and the Borrower; and

             (z)   each Increasing Lender shall have delivered to the Administrative Agent, on or prior to 9:00 a.m., New York City time, on such Commitment Increase Date, confirmation in writing satisfactory to the Administrative Agent as to its increased Commitment, with a copy of such confirmation to the Borrower.

             (iii)   Recordation. Upon receipt by the Administrative Agent of confirmation from a Lender that it is increasing its Commitment hereunder, together with the certificate referred to in clause (ii)(x) above, the Administrative Agent shall (A) record the information contained therein in the appropriate records maintained by the Administrative Agent and (B) give prompt notice thereof to the Borrower. Upon receipt by the Administrative Agent of an Assumption Agreement executed by an Assuming Lender, together with the certificate referred to in clause (ii)(x) above, the Administrative Agent shall, if such Assumption Agreement has been completed and is in substantially the form of Exhibit C, (x) accept such Assumption Agreement, (y) record the information contained therein in the appropriate records maintained by the Administrative
Agent and (z) give prompt notice thereof to the Borrower.

             (iv)   Adjustments of Borrowings upon Effectiveness of Increase. In the event that the Administrative Agent shall have received notice from the Borrower as to any agreement with respect to a Commitment Increase on or prior to the relevant Commitment Increase Date and the actions provided for in clauses (ii)(x) through (ii)(z) above shall have occurred by 9:00 a.m., New York City time, on such Commitment Increase Date, the Administrative Agent shall notify the Lenders (including any Assuming Lenders) of the occurrence of such Commitment Increase Date promptly on 

24

such date by facsimile transmission or electronic messaging system. On the date of such increase, the Borrower shall each prepay their respective then outstanding Loans (if any) in full, and shall simultaneously borrow new Loans hereunder in an amount equal to such prepayment, so that, after giving effect thereto, the Loans of the respective Lenders to each Borrower are held ratably by the Lenders in accordance with their respective Commitments (after giving effect to such Commitment Increases). Prepayments made under this clause (iv) shall not be subject to the notice requirements of Section 2.9.

SECTION 2.7. Repayment of Loans.

             The outstanding principal amount of all Loans shall be due and payable (together with accrued and unpaid interest thereon) on the Termination Date.

SECTION 2.8. Evidence of Indebtedness.

             (a)   Each Lender shall maintain in accordance with its usual practice appropriate records evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender from time to time, including the amounts of principal and interest payable thereon and paid to such Lender from time to time under this Agreement. The Administrative Agent shall maintain appropriate records in which shall be recorded (i) the Commitment, (ii) the amount of each Loan made thereunder by each Lender, the Type thereof and the Interest Period applicable thereto, (iii) the date of each continuation thereof pursuant to Section 2.5, (iv) the date of each conversion of all or a portion thereof to another Type pursuant to Section 2.5, (v) the date and amount of any principal or interest due and payable or to become due and payable from the Borrower to each
Lender hereunder in respect of such Loans and (vi) both the date and amount of any sum received by the Administrative Agent hereunder from the Borrower in respect of the Loans and each Lender’s Pro Rata Share thereof. The entries made in such records shall be prima facie evidence of the existence and amounts of the obligations of the Borrower therein recorded; provided, that the failure or delay of any Lender or the Administrative Agent in maintaining or making entries into any such record or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans (both principal and unpaid accrued interest) of such Lender in accordance with the terms of this Agreement.

             (b)   At the request of any Lender at any time, the Borrower agrees that it will execute and deliver to such Lender a note, in form and substance mutually acceptable to the Administrative Agent and the Borrower, payable to the order of such Lender.

SECTION 2.9. Optional Prepayments. 

             The Borrower shall have the right at any time and from time to time to prepay any Borrowing, in whole or in part, without premium or penalty, by giving irrevocable written notice (or telephonic notice promptly confirmed in writing) to the Administrative Agent no later than (i) in the case of prepayment of any Eurodollar Borrowing, 11:00 a.m. not less than three Business Days prior to any such prepayment, and (ii) in the case of any prepayment of any Base Rate Borrowing, by 11:00 a.m. on the date of such prepayment. Each such notice shall be irrevocable and shall specify the proposed date of such prepayment and the principal amount of each Borrowing or portion thereof to be prepaid. Upon receipt of any such notice, the Administrative 

25

Agent shall promptly notify each affected Lender of the contents thereof and of such Lender’s Pro Rata Share of any such prepayment. If such notice
is given, the aggregate amount specified in such notice shall be due and payable on the date designated in such notice, together with accrued interest to such date on the amount so prepaid in accordance with Section 2.10; provided, that if a Eurodollar Borrowing is prepaid on a date other than the last day of an Interest Period applicable thereto, the Borrower shall also pay all amounts required pursuant to Section 2.16. Each partial prepayment of any Loan shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type pursuant to Section 2.3. Each prepayment of a Borrowing shall be applied ratably to the Loans comprising such Borrowing. 

SECTION 2.10. Interest on Loans.

             (a)   The Borrower shall pay interest on each Eurodollar Loan at the Adjusted LIBO Rate for the applicable Interest Period in effect for such Loan plus the Applicable Margin in effect from time to time, and on each Base Rate Loan at the Base Rate plus the Applicable Margin in effect from time to time.

             (b)   While an Event of Default has occurred and is continuing or after acceleration, at the option of the Required Lenders, the Borrower shall pay interest (“Default Interest”) with respect to all Eurodollar Loans at the
rate otherwise applicable for the then current Interest Period plus an additional 2% per annum until the last day of such Interest Period, and thereafter, and with respect to all Base Rate Loans and all other Obligations hereunder (other than Loans), at an all in rate in effect for Base Rate Loans, plus an additional 2% per annum.

             (c)   Interest on the principal amount of all Loans shall accrue from and including the date such Loans are made to but excluding the date of any repayment thereof. Interest on all outstanding Base Rate Loans shall be payable quarterly in arrears on the last day of each fiscal quarter of the Borrower and on the Termination Date. Interest on all outstanding Eurodollar Loans shall be payable on the last day of each Interest Period applicable thereto, and on the Termination Date. Interest on any Loan that is converted into a Loan of another Type or that is repaid or prepaid shall be payable on the date of such conversion or on the date of any such repayment or prepayment (on the amount repaid or prepaid) thereof. All Default Interest shall be payable on demand.

             (d)   The Administrative Agent shall determine each interest rate applicable to the Loans hereunder and shall promptly notify the Borrower and the Lenders of such rate in writing (or by telephone, promptly confirmed in writing). Any such determination shall be conclusive and binding for all purposes, absent manifest error.

SECTION 2.11. Fees.

             (a)   The Borrower shall pay to the Administrative Agent for its own account fees in the amounts and at the times previously agreed upon by it in the Fee Letter. 

             (b)   The Borrower agrees to pay to the Administrative Agent for the account of each Lender a facility fee on each Lender’s Commitment, regardless of usage, from the date hereof in the case of each initial Lender and from the effective date specified in the Assignment and Acceptance pursuant to which it became a Lender in the case of each other Lender payable at a 

26

rate per annum equal to the Facility Fee Rate, until the Termination Date, payable on the last day of each March, June, September and December and on the Termination Date.

             (c)   The Borrower agrees to pay to the Administrative Agent for the account of each Lender a utilization fee on each Lender’s Commitment at any time the aggregate amount of all Extensions of Credit made hereunder exceeds 33% of the Aggregate Commitments. The utilization fee shall be payable at a rate per annum equal to the Utilization Fee Rate, payable on the last day of each March, June, September and December and on the Termination Date.

             (d)   The Borrower shall pay to the Administrative Agent for the account of each Lender (including, without limitation the Issuing Bank in its capacity as Lender) the LC Fee on each Lender’s Pro Rata Share of the average daily amount of the sum of the undrawn stated amounts of all Letters of Credit outstanding on each such day, from the date hereof until the later to occur of the Termination Date and the date that no Letters of Credit are outstanding, payable on the last day of each March, June, September and December and on the later to occur of the Termination Date and the date that no Letters of Credit are outstanding. In addition, the Borrower shall pay to the Administrative Agent for the account of the Issuing Bank (i) a fronting fee on the average daily amount of the sum of the undrawn amounts of all Letters of
Credit outstanding on each such day, from the date hereof until the later to occur of the Termination Date and the date that no Letters of Credit are outstanding, payable on the last day of each March, June, September and December and on such later date, at a rate equal to .15% per annum, and (ii) such documentary and processing charges in connection with the issuance, amendment, renewal or extension of, and each draw under, each Letter of Credit in accordance with the Issuing Bank’s standard schedule for such charges as in effect from time to time. 

SECTION 2.12. Computation of Interest and Fees.

             All computations of interest and fees hereunder shall be made on the basis of a year of 360 days for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or fees are payable (to the extent computed on the basis of days elapsed). Each determination by the Administrative Agent of an interest amount or fee hereunder shall be made in good faith and, except for manifest error, shall be final, conclusive and binding for all purposes. 

SECTION 2.13. Inability to Determine Interest Rates. 

             If prior to the commencement of any Interest Period for any Eurodollar Borrowing, 

             (i)   the Administrative Agent shall have determined (which determination shall be conclusive and binding upon the Borrower) that, by reason of circumstances affecting the relevant interbank market, adequate means do not exist for ascertaining LIBOR for such Interest Period, or 

             (ii)   the Administrative Agent shall have received notice from the Required Lenders that the Adjusted LIBO Rate does not adequately and fairly reflect the cost to such Lenders of making, funding or maintaining their Eurodollar Loans for such Interest Period,

27

the Administrative Agent shall give written notice (or telephonic notice, promptly confirmed in writing) to the Borrower and to the Lenders as soon as practicable thereafter. Until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) the obligations of the Lenders to make Eurodollar Loans or to continue or convert outstanding Loans as or into Eurodollar Loans shall be suspended and  (ii) all such affected Loans shall be converted into Base Rate Loans on the last day of the then current Interest Period applicable thereto unless the Borrower prepays such Loans in accordance with this Agreement. Unless the Borrower notifies the Administrative Agent at least one Business Day before the date of any Eurodollar Borrowing for which a Notice of Borrowing has previously been given that it elects not to borrow on such date, then such Borrowing shall be made as a Base Rate Borrowing. 

SECTION 2.14. Illegality. 

             If any Change in Law shall make it unlawful or impossible for any Lender to make, maintain or fund any Eurodollar Loan and such Lender shall so notify the Administrative Agent, the Administrative Agent shall promptly give notice thereof to the Borrower and the other Lenders, whereupon until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such suspension no longer exist, the obligation of such Lender to make Eurodollar Loans, or to continue or convert outstanding Loans as or into Eurodollar Loans, shall be suspended. In the case of the making of a Eurodollar Borrowing, such Lender’s Loan shall be made as a Base Rate Loan as part of the same Borrowing for the same Interest Period and if the affected Eurodollar Loan is then outstanding, such Loan shall be converted to a Base Rate Loan either (i) on the last day of the then current
Interest Period applicable to such Eurodollar Loan if such Lender may lawfully continue to maintain such Loan to such date or (ii) immediately if such Lender shall determine that it may not lawfully continue to maintain such Eurodollar Loan to such date. Notwithstanding the foregoing, the affected Lender shall, prior to giving such notice to the Administrative Agent, designate a different Applicable Lending Office if such designation would avoid the need for giving such notice and if such designation would not otherwise be disadvantageous to such Lender in the good faith exercise of its discretion.

SECTION 2.15. Increased Costs.

             (a)   If any Change in Law shall:

             (i)   impose, modify or deem applicable any reserve, special deposit or similar requirement that is not otherwise included in the determination of the Adjusted LIBO Rate hereunder against assets of, deposits with or for the account of, or credit extended by, any Lender or the Issuing Bank (each a “Claimant”) (except any such reserve requirement reflected in the Adjusted LIBO Rate); or 

             (ii)   impose
    on any Claimant or the eurodollar interbank market any other condition affecting
    this Agreement or any Eurodollar Loans or other Extension of Credit made by
    such Claimant, excluding any change in Excluded Taxes;

	and the result of the
    foregoing is to increase the cost to such Claimant of making, converting into, continuing or maintaining a Eurodollar Loan or other Extension of Credit or to increase the 

28

cost to such Claimant or to reduce the amount received or receivable by such Claimant hereunder (whether of principal, interest or any other amount), then the Borrower shall promptly pay, upon written notice from and demand by such Claimant on the Borrower (with a copy of such notice and demand to the Administrative Agent), to the Administrative Agent for the account of such Claimant, within five Business Days after the date of such notice and demand, additional amount or amounts sufficient to compensate such Claimant for such additional costs incurred or reduction suffered. 

             (b)   If any Claimant shall have determined that on or after the date of this Agreement any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Claimant’s capital (or on the capital of such Claimant’s parent corporation) as a consequence of its obligations hereunder to a level below that which such Claimant or such Claimant’s parent corporation could have achieved but for such Change in Law (taking into consideration such Claimant’s policies or the policies of such Claimant’s parent corporation with respect to capital adequacy) then, from time to time, within five Business Days after receipt by the Borrower of written demand by such Claimant (with a copy thereof to the Administrative Agent), the Borrower shall pay to such Claimant such additional amounts as will compensate such
Claimant or such Claimant’s parent corporation for any such reduction suffered. 

             (c)   A certificate of a Claimant setting forth the amount or amounts necessary to compensate such Claimant or such Claimant’s parent corporation, as the case may be, specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower (with a copy to the Administrative Agent) and shall be conclusive, absent manifest error. The Borrower shall pay any such Lender such amount or amounts within 10 days after receipt thereof.

             (d)   Failure or delay on the part of any Claimant to demand compensation pursuant to this Section shall not constitute a waiver of such Claimant’s right to demand such compensation.

SECTION 2.16. Funding Indemnity. 

             In the event of (i) the payment of any principal of a Eurodollar Loan other than on the last day of the Interest Period applicable thereto (including as a result of an Event of Default), (ii) the conversion or continuation of a Eurodollar Loan other than on the last day of the Interest Period applicable thereto, or (iii) the failure by the Borrower to borrow, prepay, convert or continue any Eurodollar Loan on the date specified in any applicable notice (regardless of whether such notice is withdrawn or revoked), or (iv) any repayment of all or any portion of any Eurodollar Borrowing other than on the last day of an Interest Period therefor as a result of a request by the Borrower for a Commitment Increase pursuant to Section 2.6(c) and a resulting adjustment of outstanding Borrowings as among Lenders under paragraph (iv) of such Section, then, in any such event, the Borrower
shall compensate each Lender, within five Business Days after written demand from such Lender, for any loss, cost or expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense shall be deemed to include an amount determined by such Lender to be the excess, if any, of (A) the amount of interest that would have accrued on the principal amount of such Eurodollar Loan if such event had not occurred at the Adjusted LIBO Rate applicable to such Eurodollar Loan for the period from the date of such event to the last day of the then current Interest Period therefor (or in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Eurodollar Loan) 

29

over (B) the amount of interest that would accrue on the principal amount of such Eurodollar Loan for the same period if the Adjusted LIBO Rate were set on the date such Eurodollar Loan was prepaid or converted or the date on which the Borrower failed to borrow, convert or
continue such  Eurodollar Loan. A certificate as to any additional amount payable under this Section 2.16 submitted to the Borrower by any Lender (with a copy to the Administrative Agent) shall be conclusive, absent manifest error.

SECTION 2.17. Taxes.

             (a)   Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided, that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent, the Issuing Bank or any Lender (as the case may be) shall receive an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

             (b)   In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

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

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

             (e)   Any Foreign Lender and if applicable, the Issuing Bank, that is entitled to an exemption from or reduction of withholding tax under the Code or any treaty to which the United States is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a 

30

reduced rate. Without limiting the generality of the foregoing, each Foreign Lender, or the Issuing Bank, agrees that it will deliver to the Administrative Agent, the Issuing Bank and the Borrower (or in the case of a Participant, to the Lender from which the related participation shall have been purchased), as appropriate,
two duly completed copies of (i) Internal Revenue Service Form W-8 ECI, or any successor form thereto, certifying that the payments received from the Borrower hereunder are effectively connected with such Foreign Lender’s or the Issuing Bank’s conduct of a trade or business in the United States; or (ii) Internal Revenue Service Form W-8 BEN, or any successor form thereto, certifying that such Foreign Lender or the Issuing Bank is entitled to benefits under an income tax treaty to which the United States is a party which reduces the rate of withholding tax on payments of interest; or (iii) Internal Revenue Service Form W-8 BEN, or any successor form prescribed by the Internal Revenue Service, together with a certificate (A) establishing that the payment to the Foreign Lender qualifies as “portfolio interest” exempt from U.S. withholding tax under Code section 871(h) or 881(c), and (B) stating that (1) the Foreign Lender or the Issuing Bank is not a bank for purposes of Code
section 881(c)(3)(A), or the obligation of the Borrower hereunder is not, with respect to such Foreign Lender or the Issuing Bank, a loan agreement entered into in the ordinary course of its trade or business, within the meaning of that section; (2) the Foreign Lender or the Issuing Bank is not a 10% shareholder of the Borrower within the meaning of Code section 871(h)(3) or 881(c)(3)(B); and (3) the Foreign Lender or the Issuing Bank is not a controlled foreign corporation that is related to the Borrower within the meaning of Code section 881(c)(3)(C); or (iv) such other Internal Revenue Service forms as may be applicable to the Foreign Lender, including Forms W-8 IMY or W-8 EXP. Each such Foreign Lender or the Issuing Bank shall deliver to the Borrower, the Issuing Bank and the Administrative Agent such forms on or before the date that it becomes a party to this Agreement (or in the case of a Participant, on or before the date such Participant purchases the related participation). In addition,
each such Foreign Lender shall deliver such forms promptly upon the obsolescence or invalidity of any form previously delivered by such Foreign Lender. Each such Foreign Lender shall promptly notify the Borrower, the Issuing Bank and the Administrative Agent at any time that it determines that it is no longer in a position to provide any previously delivered certificate to the Borrower (or any other form of certification adopted by the Internal Revenue Service for such purpose). 

SECTION 2.18. Payments Generally; Pro Rata Treatment; Sharing of Setoffs. 

             (a)   The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees or of amounts payable under Section 2.15, 2.16 or 2.17, or otherwise) prior to 12:00 noon, on the date when due, in immediately available funds, free and clear of any defenses, rights of setoff, counterclaim, or withholding or deduction of taxes. Any amounts received after such time on any date may be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at the Payment Office, except that payments pursuant to Sections 2.15, 2.16 and 2.17 and 10.3 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient
promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be made payable for the period of such extension. All payments hereunder shall be made in Dollars.

31

             (b)   If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties.

             (c)   If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or an account of the Borrower’s reimbursement obligations in respect of such Lender’s participation in an LC Disbursement that would result in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and such reimbursement obligations of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans; provided,
that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of setoff and counterclaim with respect to such participation as fully as
if such Lender were a direct creditor of the Borrower in the amount of such participation.

             (d)   Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders the amount or amounts due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate
determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

             (e)   If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.18(d) or 10.3(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid.

32

SECTION 2.19. Mitigation of Obligations. 

             If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the sole judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable under Section 2.15 or Section 2.17, as the case may be,  in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous  to such Lender. The Borrower hereby agrees to pay all costs and expenses incurred by any Lender in connection with such designation or assignment.

SECTION 2.20. Letters of Credit.

             (a)   The Issuing Bank, in reliance upon the agreements of the other Lenders pursuant to Section 2.20(d), agrees to issue, at the request of the Borrower, Letters of Credit for the account of the Borrower and to make LC Disbursements payable in accordance with the terms and conditions of Letters of Credit issued hereunder, all on the terms and conditions set forth herein; provided, that (i) each Letter of Credit shall expire no later than the date that is five Business Days prior to the Termination Date; (ii) each Letter of Credit shall be in a stated amount no
less than $100,000; and (iii) the Borrower may not request any Letter of Credit, if, after giving effect to such issuance the aggregate LC Exposure would exceed the LC Commitment. Upon the issuance of each Letter of Credit each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Issuing Bank without recourse a participation in such Letter of Credit equal to such Lender’s Pro Rata Share of the aggregate amount available to be drawn under such Letter of Credit. Each issuance of a Letter of Credit shall be deemed to utilize the Commitment of each Lender by an amount equal to the amount of such participation.

             (b)   To request the issuance of a Letter of Credit (or any amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall give the Issuing Bank and the Administrative Agent an irrevocable Request for Issuance by delivering such Request for Issuance to both the Issuing Bank and the Administrative Agent not later than 1:00 p.m. (Central time) one Business Day prior to the requested date of such issuance (or amendment, renewal or extension, as the case may be). In addition to the satisfaction of the conditions in Article III (the satisfaction of which the Issuing Bank shall have no duty to ascertain), the issuance of each Letter of Credit (or any amendment that increases the amount of a Letter of Credit) will be subject to the further conditions that such Letter of Credit shall be in such form and contain such terms as the Issuing Bank shall approve and
that the Borrower shall have executed and delivered to the Issuing Bank such application or reimbursement agreement, and/or such other instruments and agreements relating to such Letter of Credit, if any, as the Issuing Bank may have reasonably requested. In the event of any conflict between the terms of any such application, agreement or instrument and the terms of this Agreement, the terms of this Agreement shall control. At the request of the Borrower, any Letter of Credit may be issued designating a subsidiary of the Borrower as a nominal account party in respect of such Letter of Credit, but no such designation shall in any manner limit or impair, or relieve the Borrower of, the obligations of the Borrower 

33

hereunder and in respect of such Letter of Credit, it being understood and agreed that, as among the several parties to this Agreement, the Borrower shall at all times have all of the rights and be subject to all of the obligations, duties and responsibilities of an account party with respect
to each letter of Credit whether or not such Letter of Credit refers to the Borrower as the account party with respect to such Letter of Credit.

             (c)   Unless the Issuing Bank has received notice from the Administrative Agent on or before 1:00 p.m (Central time) on the requested date of such issuance (or amendment, renewal or extension, as the case may be) directing the Issuing Bank not to issue the Letter of Credit because such issuance (or amendment, renewal or extension, as the case may be) is not then permitted hereunder because of the limitations set forth in Section 2.20(a) or that one or more conditions specified in Article III are not then satisfied, then, subject to the terms and conditions of this Section 2.20, the Issuing Bank shall, on the requested date, issue such Letter of Credit (or amendment, renewal or extension, as the case may be) in accordance with the Issuing Bank’s usual and customary business practices, and provide notice and a copy thereof to the Administrative Agent.

             (d)   The Issuing Bank shall examine all documents purporting to represent a demand for payment under a Letter of Credit promptly following its receipt thereof. The responsibility of the Issuing Bank to the Borrower and each Lender shall be only to determine that the documents (including each demand for payment) delivered under each Letter of Credit in connection with such presentment shall be in conformity in all material respects with such Letter of Credit, and the Issuing Bank shall endeavor to exercise the same care in the issuance and administration of the Letters of Credit as it does with respect to letters of credit in which no participations are granted. The Issuing Bank shall promptly notify the Borrower and the Administrative Agent of each demand for payment under a Letter of Credit and whether the Issuing Bank has made or will make a LC Disbursement
thereunder; provided, that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank and the Lenders with respect to such LC Disbursement. The Borrower shall be irrevocably and unconditionally obligated to reimburse the Issuing Bank for any LC Disbursements paid by the Issuing Bank in respect of such drawing, without presentment, demand or other formalities of any kind. Unless the Borrower shall have notified the Issuing Bank and the Administrative Agent prior to 10:00 a.m. (Central time) on the Business Day immediately prior to the date on which such drawing is honored that the Borrower intends to reimburse the Issuing Bank for the amount of such drawing in funds other than from the proceeds of Loans, the Borrower shall be deemed to have timely given a Notice of Borrowing to the Administrative Agent requesting the Lenders to make a Base Rate Borrowing on the date on which such drawing is honored in an exact amount due to the
Issuing Bank; provided, that for purposes solely of such Borrowing, the conditions precedents set forth in Section 3.2 hereof shall not be applicable. The Administrative Agent shall notify the Lenders of such Borrowing in accordance with Section 2.3, and each Lender shall make the proceeds of its Base Rate Loan included in such Borrowing available to the Administrative Agent for the account of the Issuing Bank in accordance with Section 2.8. The proceeds of such Borrowing shall be applied directly by the Administrative Agent to reimburse the Issuing Bank for such LC Disbursement.

             (e)   If for any reason a Base Rate Borrowing may not be (as determined in the sole discretion of the Administrative Agent), or is not, made in accordance with the foregoing 

34

provisions, then each applicable Lender (other than the Issuing Bank) shall be obligated to fund the participation that such Lender purchased pursuant to subsection (a) in an amount equal to its Pro Rata Share of such LC Disbursement on and as of the date which such Base Rate Borrowing should have occurred. Each Lender’s obligation to fund its participation shall be absolute and unconditional and shall not be affected by any circumstance, including without limitation (i) any setoff, counterclaim, recoupment, defense or other right that such Lender or any other Person may have against any beneficiary of a Letter of Credit, the Issuing Bank or any other Person for any reason whatsoever, (ii) the
existence of a Default or an Event of Default or the termination of the Commitments, (iii) any adverse change in the condition (financial or otherwise) of the Borrower or any of its Subsidiaries, (iv) any breach of this Agreement by the Borrower or any other Lender, (v) any amendment, renewal or extension of any Letter of Credit or (vi) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. On the date that such participation is required to be funded, each Lender shall promptly transfer, in immediately available funds, the amount of its participation to the Administrative Agent for the account of the Issuing Bank. Whenever, at any time after the Issuing Bank has received from any such Lender the funds for its participation in a LC Disbursement, the Issuing Bank (or the Administrative Agent on its behalf) receives any payment on account thereof, the Administrative Agent or the Issuing Bank, as the case may be, will distribute to such Lender its Pro Rata
Share of such payment; provided, that if such payment is required to be returned for any reason to the Borrower making such payment or to a trustee, receiver, liquidator, custodian or similar official in any bankruptcy proceeding, such Lender will return to the Administrative Agent or the Issuing Bank any portion thereof previously distributed by the Administrative Agent or the Issuing Bank to it.

             (f)   To the extent that any Lender shall fail to pay any amount required to be paid pursuant to subsection (d) of this Section 2.20 on the due date therefor, such Lender shall pay interest to the Issuing Bank (through the Administrative Agent) on such amount from such due date to the date such payment is made at a rate per annum equal to the Federal Funds Rate; provided, that if such Lender shall fail to make such payment to the Issuing Bank within three Business Days of such due date, then, retroactively to the due date, such Lender shall be obligated to pay Default Interest on such amount.

             (g)   If any Event of Default shall occur and be continuing, on the Business Day that the Borrower receives notice from the Administrative Agent or the Required Lenders demanding the deposit of cash collateral pursuant to this paragraph, the Borrower shall deposit in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Issuing Bank and the Lenders, an amount in cash equal to the LC Exposure as of such date plus any accrued and unpaid fees thereon; provided, that the obligation to deposit such cash collateral shall  become effective immediately, and such deposit shall become immediately due and payable, without demand or notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower described in clause (g) or (h) of Section 8.1. Such deposit shall be held by the Administrative Agent as
collateral for the payment and performance of the obligations of the Borrower under this Agreement. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. The Borrower agrees to execute any documents and/or certificates to effectuate the intent of this paragraph. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent and at the Borrower’s 

35

risk and expense, such deposits shall not bear interest. Interest and profits, if any, on such investments shall accumulate in such account. Moneys in such account shall applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it had not been reimbursed and to the extent so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been
accelerated, with the consent of the Required Lenders, be applied to satisfy other obligations of the Borrower under this Agreement. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not so applied as aforesaid) shall be returned to the Borrower with three Business Days after all Events of Default have been cured or waived.

             (h)   Promptly following the end of each fiscal quarter, the Issuing Bank shall deliver (through the Administrative Agent) to each Lender and the Borrower a report describing the aggregate Letters of Credit outstanding at the end of such fiscal quarter. Upon the request of any Lender from time to time, the Issuing Bank shall deliver to such Lender any other information reasonably requested by such Lender with respect to each Letter of Credit then outstanding.

             (i)   The Borrower’s obligations to reimburse LC Disbursements hereunder shall be absolute, unconditional and irrevocable and shall be performed strictly in accordance with the terms of this Agreement under all circumstances whatsoever and irrespective of any of the following circumstances:

             (i)   Any lack of validity or enforceability of any Letter of Credit or this Agreement;

             (ii)   The existence of any claim, set-off, defense or other right which the Borrower or any Lender or any Subsidiary or Affiliate of the Borrower or any Lender may have at any time against a beneficiary or any transferee of any Letter of Credit (or any Persons or entities for whom any such beneficiary or transferee may be acting), any Lender (including the Issuing Bank) or any other Person, whether in connection with this Agreement or the Letter of Credit or any document related hereto or thereto or any unrelated transaction; 

             (iii)   Any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect;

             (iv)   Payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document to the Issuing Bank that does not comply with the terms of such Letter of Credit;

             (v)   Any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit;

             (vi)   Any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or 

36

equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder; or

             (vii)   The existence of a Default or an Event of Default.

             (j)   Each Letter of Credit shall be subject to (i) either (as selected by the Issuing Bank from time to time) (A) the Uniform Customs and Practices for Documentary Credits (1993 Revision), International Chamber of Commerce Publication No. 500, as the same may be amended from time to time, or (B) the International Standby Practices 1998 (ISP98), International Chamber of Commerce Publication No. 590, as the same may be amended from time to time, and (ii) to the extent not inconsistent therewith, the governing law of this Agreement set forth in Section 10.5.

             (k)   Neither the Administrative Agent, the Issuing Bank, the Lenders nor any Related Party of any of the foregoing shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to above), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided, that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrower to the extent of any direct damages (as opposed to
consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by either (x) the Issuing Bank’s gross negligence or willful misconduct (as finally determined by a court of competent jurisdiction) when determining whether drafts or other documents presented under a Letter of Credit comply with the terms thereof, or (y) the Issuing Bank’s failure to pay under any Letter of Credit after the presentation to it of a request strictly complying with the terms and conditions of such Letter of Credit. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented that appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice
or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

             (l)   The Borrower hereby agrees to indemnify and hold harmless each Lender, the Issuing Bank and the Administrative Agent, and their respective directors, officers, agents and employees from and against any and all claims and damages, losses, liabilities, costs or expenses which such Lender, the Issuing Bank or the Administrative Agent may incur (or that may be claimed against such Lender, the Issuing Bank or the Administrative Agent by any Person whatsoever) by reason of or in connection with the issuance, execution and delivery or transfer of or payment or failure to pay under any Letter of Credit or any actual or proposed use of any Letter of Credit, including, without
limitation, any claims, damages, losses, liabilities, costs or expenses which the Issuing Bank may incur by reason of or in connection with (i) the failure of any other Lender to fulfill or comply with its obligations to the Issuing Bank hereunder (but nothing herein contained shall affect any rights the Borrower may have against any defaulting 

37

Lender) or (ii) by reason of or on account of the Issuing Bank issuing any Letter of Credit that specifies that the term “Beneficiary” included therein includes any successor by operation of law of the named Beneficiary, but which Letter of Credit does not require that any drawing by any such successor Beneficiary be accompanied by a copy of a legal document, satisfactory to the Issuing Bank, evidencing the appointment of such successor Beneficiary; provided that the Borrower shall not be required to indemnify any Lender, the Issuing Bank or the Administrative Agent for any claims, damages, losses,
liabilities, costs or expenses to the extent, but only to the extent, caused by (x) the willful misconduct or gross negligence of the Issuing Bank (as finally determined by a court of competent jurisdiction) or (y) the Issuing Bank’s failure to pay under any Letter of Credit after the presentation to it of a request strictly complying with the terms and conditions of such Letter of Credit. Nothing in this Section 2.20(l) is intended to limit the obligations of the Borrower under any other provision of this Agreement.

             (m)   Each Lender hereby agrees to indemnify, ratably in accordance with its Pro Rata Share, the Issuing Bank, its affiliates and their respective directors, officers, agents and employees (to the extent not reimbursed by the Borrower) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from such indemnitees’ gross negligence or willful misconduct or the Issuing Bank’s failure to pay under any Letter of Credit after the presentation to it of a request strictly complying with the terms and conditions of such Letter of Credit) that such indemnitees may suffer or incur in connection with this Section 2.20 or any action taken or omitted by such indemnitees hereunder.

ARTICLE III
CONDITIONS PRECEDENT TO EXTENSIONS OF CREDIT

SECTION 3.1. Conditions To Initial Extensions of Credit. 

             The obligations of the Lenders and the Issuing Bank to make Extensions of Credit shall not become effective until the date on which each of the following conditions is satisfied (or waived in accordance with Section 10.2).

             (a)   The Administrative Agent, the Lenders and the Issuing Bank shall have received all fees and other amounts due and payable on or prior to the date of the initial Extension of Credit, including reimbursement or payment of all out-of-pocket expenses (including reasonable fees, charges and disbursements of counsel to the Administrative Agent) required to be reimbursed or paid by the Borrower hereunder, under any other Loan Document and under the Fee Letter.

             (b)   The Administrative Agent (or its counsel) shall have received the following (each of which, unless otherwise specified, shall be dated on or as of a single date occurring on or before the date of the Initial Extension of Credit):

             (i)   a counterpart of this Agreement signed by or on behalf of each party hereto or written evidence satisfactory to the Administrative Agent (which may include a 

38

ARTICLE IV
REPRESENTATIONS AND WARRANTIES

             The Borrower represents and warrants to the Administrative Agent, the Issuing Bank and each Lender as follows:

SECTION 4.1. Existence; Power. 

             The Borrower and each of its Subsidiaries (i) is duly organized, validly existing and in good standing as a limited liability company or corporation under the laws of the jurisdiction of its organization, (ii) has all requisite power and authority to carry on its business as now 

40

conducted, and (iii) is duly qualified to do business, and is in good standing, in each jurisdiction where such qualification is required, except where a failure to be so qualified could not reasonably be expected to result in a Material Adverse Effect. 

SECTION 4.2. Organizational Power; Authorization. 

             The execution, delivery and performance by the Borrower of the Loan Documents are within the Borrower’s organizational powers and have been duly authorized by all necessary organizational, and if required, member action. This Agreement has been duly executed and delivered by the Borrower, and constitutes a valid and binding obligation of the Borrower, enforceable against it in accordance with its terms, except as may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, or similar laws affecting the enforcement of creditors’ rights generally and by general principles of equity.

SECTION 4.3. Governmental Approvals; No Conflicts. 

             The execution, delivery and performance by the Borrower of this Agreement, and of the other Loan Documents to which it is a party (i) do not require any consent or approval of, registration or filing with, or any action by, any Governmental Authority, except those as have been obtained or made and are in full force and effect, or where the failure to do so could not reasonably be expected to have a Material Adverse Effect, (ii) will not violate any applicable law, rule or regulation or the charter, certificate of formation, bylaws, limited liability company agreement, or other organizational documents of the Borrower or any of its Subsidiaries or any judgment, order or ruling of any Governmental Authority, (iii) will not violate or result in a default under any indenture, material agreement or other material instrument binding on the Borrower or any of its Subsidiaries or any of its assets
or give rise to a right thereunder to require any payment to be made by the Borrower or any of its Subsidiaries and (iv) will not result in the creation or imposition of any Lien on any asset of the Borrower or any of its Subsidiaries.

SECTION 4.4. Financial Statements. 

             The Borrower has furnished to each Lender the audited consolidated balance sheet of the Borrower and its Subsidiaries as of December 31, 2000 and December 31, 2001 and the related consolidated statements of income, shareholders’ equity and cash flows for the fiscal year then ended audited by PricewaterhouseCoopers. Such financial statements fairly present the consolidated financial condition of the Borrower and its Subsidiaries as of such dates and the consolidated results of operations for such periods in conformity with GAAP consistently applied, subject to year-end audit adjustments. Since December 31, 2001, there have been no changes with respect to the Borrower and its Subsidiaries that have had or could reasonably be expected to have, singly or in the aggregate, a Material Adverse Effect; provided, that changes in the Borrower’s trading positions arising in the
ordinary course of business shall be viewed in the aggregate rather than on an individual trading position basis.

SECTION 4.5. Litigation and Environmental Matters.

             (a)   No litigation, investigation or proceeding of or before any arbitrators or Governmental Authorities is pending against or, to the knowledge of the Borrower, threatened against or affecting the Borrower or any of its Subsidiaries (i) that would reasonably be expected 

41

to have a Material Adverse Effect or (ii) that in any manner draws into question the validity or enforceability of this Agreement or any other Loan Document.

             (b)   Except for the matters set forth on Schedule 4.5, neither the Borrower nor any of its Subsidiaries (i) has failed to comply with any Environmental Law or to obtain, maintain or comply with any permit, license or other approval required under any Environmental Law, (ii) has incurred or, to the knowledge of the Borrower, otherwise become subject to any Environmental Liability, (iii) has received notice of any claim with respect to any
Environmental Liability or (iv) knows of any potential claim for any Environmental Liability, in each case that could reasonably be expected to have a Material Adverse Effect.

SECTION 4.6. Compliance with Laws and Agreements. 

             The Borrower and each of its Subsidiaries is in compliance with (i) all applicable laws, rules, regulations, judgments and orders of any Governmental Authority, and (ii) all indentures, agreements or other instruments binding upon it or its properties, except where noncompliance would not have a Material Adverse Effect. 

SECTION 4.7. Investment Company Act, Etc. 

             Neither the Borrower nor any of its Subsidiaries is an “investment company” or is “controlled” by an “investment company”, as such terms are defined in, or subject to regulation under, the Investment Company Act of 1940, as amended. The Borrower is a “holding company” as defined in, or subject to regulation under, the Public Utility Holding Company Act of 1935, as amended (“PUHCA”). Under PUHCA, the Borrower is not prohibited from incurring the Indebtedness contemplated by this Agreement. The Borrower is not otherwise subject to any other regulatory scheme limiting its ability to incur debt. The Subsidiaries of the Borrower are not restricted or prohibited by any Requirement of Law from paying cash dividends or distributions to their shareholders from retained earnings. To the extent that the Borrower and its Subsidiaries
are subject to regulation under the Federal Power Act, the Borrower and its Subsidiaries have received all necessary approvals and made all necessary filings thereunder in connection with the execution, delivery and performance of this Agreement and the other Loan Documents.

SECTION 4.8. Taxes. 

             The Borrower and each Subsidiary of the Borrower and each other Person the taxes for which the Borrower or any Subsidiary could become liable have timely filed or caused to be filed all Federal income tax returns and all other material tax returns that are required to be filed by them, and have paid all taxes shown to be due and payable on such returns or on any assessments made against it or its property and all other taxes, fees or other charges imposed on it or any of its property by any Governmental Authority, except (i) to the extent the failure to do so would not have a Material Adverse Effect or (ii) where the same are currently being contested in good faith by appropriate proceedings and for which the Borrower or such Subsidiary, as the case may be, has set aside on its books adequate reserves in accordance with GAAP. As of the date hereof, the charges, accruals and reserves
on the books of the Borrower and its Subsidiaries in 

42

respect of such taxes are adequate, and no tax liabilities that could be materially in excess of the amount so provided are anticipated.

SECTION 4.9. Margin Regulations. 

             None of the proceeds of any of the Loans will be used for “purchasing” or “carrying” any “margin stock” with the respective meanings of each of such terms under Regulation U as now and from time to time hereafter in effect or for any purpose that violates the provisions of the applicable Margin Regulations. Neither the Borrower nor any of its Subsidiaries is engaged principally, or as one of its important activities, in the business of extending credit for the purpose of purchasing or carrying any “margin stock”.

SECTION 4.10. ERISA. 

             No ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other such ERISA Events for which liability is reasonably expected to occur, could reasonably be expected to result in a Material Adverse Effect. The present value of  all accumulated  benefit obligations under each Plan (based on the assumptions used for purposes of Statement of Financial Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed the fair market value of the assets of such Plan by more than $10,000,000, and the present value of all accumulated benefit obligations of all underfunded Plans (based on the assumptions used for purposes of Statement of Financial Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed the fair market value of the assets of all such
underfunded Plans by more than $10,000,000.

SECTION 4.11. Ownership of Property.

             (a)   The Borrower and each Subsidiary of the Borrower has good title to, or valid leasehold interests in, all of its real and personal property material to the operation of its business, free and clear of any Liens except Liens permitted under Section 7.2.

             (b)   The Borrower and its Subsidiaries owns, or is licensed, or otherwise has the right, to use, all patents, trademarks, service marks, tradenames, copyrights, franchises, licenses, and other intellectual property material to its business, and the use thereof by the Borrower and its Subsidiaries does not infringe on the rights of any other Person, except for any such infringements that, individually or in the aggregate, would not have a Material Adverse Effect. 

SECTION 4.12. Disclosure. 

             The Borrower has disclosed to the Lenders all matters known to it that could reasonably be expected to result in a Material Adverse Effect. None of the reports (including all reports that the Borrower is required to file with the SEC), financial statements, certificates or other information furnished in writing by or on behalf of the Borrower to the Administrative Agent or any Lender, or to the best knowledge of the Borrower otherwise provided to the Administrative Agent, the Issuing Bank or any Lender, in connection with the negotiation of this Agreement or any other Loan Document or delivered hereunder or thereunder (as modified or supplemented by any other information so furnished) contains any material misstatement of fact or omits to state 

43

any material fact necessary to make the statements therein, taken as a whole, in light of the circumstances under which they were made, not misleading,

SECTION 4.13. Labor Relations. 

             There are no strikes, lockouts or other material labor disputes or grievances against the Borrower or any of its Subsidiaries, or, to the Borrower’s knowledge, threatened against or affecting the Borrower or any of its Subsidiaries, and no significant unfair labor practice, charges or grievances are pending against the Borrower or any of its Subsidiaries, or to the Borrower’s knowledge, threatened against any of them before any Governmental Authority that could reasonably be expected to have a Material Adverse Effect. All payments due from the Borrower or any of its Subsidiaries pursuant to the provisions of any collective bargaining agreement have been paid or accrued as a liability on the books of the Borrower or any Subsidiary, except where the failure to do so could not reasonably be expected to have a Material Adverse Effect.

SECTION 4.14. Subsidiaries. 

             Schedule 4.14 sets forth the name of, the ownership interest of the Borrower in, the jurisdiction of incorporation or organization of, and the type of, each Subsidiary of the Borrower as of the date hereof.

SECTION 4.15. Pari Passu with Other Unsubordinated Unsecured Debt. 

             The Obligations constitute Indebtedness that is pari passu with all other unsubordinated unsecured Indebtedness of the Borrower.

The bank acting as the Administrative Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of business with the Borrower or any Subsidiary or Affiliate of the Borrower as if it were not the Administrative Agent hereunder.

SECTION 9.7. Successor Administrative Agent.

             (a)   No failure or delay by the Administrative Agent, the Issuing Bank or any Lender in exercising any right or power hereunder or any other Loan Document, and no course of dealing between the Borrower and the Administrative Agent, the Issuing Bank or any Lender, shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power or any abandonment or  discontinuance of steps to enforce such right or power, preclude any other or further exercise thereof or the exercise of any other right or power hereunder or thereunder. The rights and remedies of the Administrative Agent, the Issuing Bank and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies provided by law. No waiver of any provision of this Agreement or any other Loan Document or consent
to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such 

60

waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan shall not be construed as a waiver of any Default or Event of Default, regardless of whether the Administrative Agent, the Issuing Bank or any Lender may have had notice or knowledge of such Default or Event of Default at the time.

             (b)   No amendment or waiver of any provision of this Agreement or the other Loan Documents, nor consent to any departure by the Borrower therefrom, shall in any event be effective unless the same shall be in writing and signed by the Borrower and the Required Lenders or the Borrower and the Administrative Agent with the consent of the Required Lenders and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, that no amendment or waiver shall:  (i) increase the Commitment of any Lender without the written consent of such Lender; (ii) reduce the principal amount of any Loan or any reimbursement obligation in respect of a Letter of Credit or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender and, if
applicable the Issuing Bank, affected thereby; (iii) postpone the date fixed for any payment of any principal of, or interest on, any Loan or any reimbursement obligation in respect of a Letter of Credit or interest thereon or any fees hereunder or reduce the
amount of, waive or excuse any such payment, or postpone the scheduled date for the termination or reduction of any Commitment, or allow a Letter of Credit to have an expiry date subsequent to the Termination Date without the written consent of each Lender affected thereby, and, if applicable the Issuing Bank; (iv) change Section 2.18 (b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender and the Issuing Bank; (v) change any of the provisions of this Section or the definition of “Required Lenders” or any other provision  hereof specifying the number or percentage of Lenders that are required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the consent of each Lender; (vi) release any guarantor or limit the liability of any such guarantor under any guaranty agreement, without the written consent
of each Lender; (vii) release all or substantially all collateral (if any) securing any of the Obligations without the written consent of each Lender; (viii) affect the rights or duties of the Issuing Bank under this Agreement without the written consent of the Issuing Bank; provided further, that no such agreement shall amend, modify or otherwise affect the rights, duties or obligations of the Administrative Agent without the prior written consent of such Person; and provided further, that any waiver of, or amendment to, the definition of “Change of Control” shall require the consent of Lenders holding 66-2/3% or more of the aggregate outstanding Commitments at such time, or, if the Commitments have been terminated, the consent of Lenders holding 66-2/3% or more of the aggregate outstanding Loans and obligations to participate in LC Disbursements at such time. Notwithstanding the foregoing, any provision of this Agreement may be
amended by an agreement in writing entered into by the Borrower, the Required Lenders, the Issuing Bank and the Administrative Agent if (i) by the terms of such agreement the Commitment of each Lender not consenting to the amendment provided for therein shall terminate (but such Lender shall continue to be entitled to the benefits of Sections 2.15, 2.16, and 2.17 and 10.3) upon the effectiveness of such amendment and (ii) at the time such amendment becomes effective, each Lender not consenting thereto receives payment in full of principal of and interest accrued on each Loan made by it and all other amounts owing to it or accrued for its account under this Agreement and is released from its obligations hereunder.

61

SECTION 10.3. Expenses; Indemnification.

             (a)   The Borrower shall pay (i) all reasonable, out-of-pocket costs and expenses of the Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent and its Affiliates, in connection with the preparation and administration of the Loan Documents and any amendments, modifications or waivers thereof, and (ii) all out-of-pocket costs and expenses (including, without limitation, the fees, charges and disbursements of outside counsel and the allocated cost of inside counsel) incurred by the Administrative Agent, the Issuing Bank or any Lender in connection with the enforcement or protection of its rights after the occurrence of an Event of Default in connection with this Agreement, including its rights under this Section, or in connection with the Loans made, including all such
out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans.

             (b)   The Borrower shall indemnify the Administrative Agent, the Issuing Bank and each Lender, and each Related Party of any of the foregoing (each, an “Indemnitee”) against, and hold each of them harmless from, any and all losses, claims, damages, costs, expenses (including reasonable fees, time charges and expenses of attorneys for each Indemnitee) and liabilities of any Indemnitee arising out of or relating to any litigation, investigation or other proceeding (regardless of whether the Indemnitee is a party thereto and including any legal or other expenses incurred in connection with the investigation or defense of any such litigation or other proceeding) relating to or resulting from (i) the execution or delivery of this Agreement or any other agreement or instrument contemplated hereby, the performance by the parties hereto
of their respective obligations hereunder or the consummation of any of the transactions contemplated hereby, (ii) any Loan or any actual or intended use of the proceeds therefrom, (iii) the use by the Borrower or any Beneficiary of any Letter of Credit of such Letter of Credit, (iv) any actual or alleged presence or release of Hazardous Materials on or from any property owned by the Borrower or any Subsidiary of the Borrower or any Environmental Liability related to the Borrower or any Subsidiary of the Borrower, whether based on contract, tort or any other theory and (iv) any claim against the Administrative Agent or the Issuing Bank brought by a Lender or the Issuing Bank; provided, that the Borrower shall not be obligated to indemnify any Indemnitee for any of the foregoing arising out of such Indemnitee’s gross negligence or willful misconduct as determined by a court of competent jurisdiction in a final and nonappealable judgment. 

             (c)   The Borrower shall pay, and hold the Administrative Agent, the Issuing Bank and each of the Lenders harmless from and against, any and all present and future stamp, documentary, and other similar taxes with respect to this Agreement and any other Loan Documents, any collateral described therein, or any payments due
thereunder, and save the Administrative Agent and each Lender harmless from and against any and all liabilities with respect to or resulting from any delay or omission to pay such taxes.

             (d)   To the extent that the Borrower fails to pay any amount required to be paid to the Administrative Agent or the Issuing Bank under clauses (a), (b) or (c) hereof, each Lender severally agrees to pay to the Administrative Agent, such Lender’s Pro Rata Share (determined as of the time that the unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided, that the unreimbursed expense or indemnified payment, claim, damage, 

62

liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent or the Issuing Bank in its capacity as such.

             (e)   To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to actual or direct damages) arising out of, in connection with or as a result of, this Agreement or any agreement or instrument contemplated hereby, the transactions contemplated therein, any Loan or the use of proceeds thereof.

             (f)   All amounts due under this Section shall be payable promptly after written demand therefor. 

SECTION 10.4. Successors and Assigns.

             (a)   The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and
their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder (other than to an assignee expressly permitted or not restricted under Section 7.3 hereof) without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

             (b)   Any Lender may assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment, the Loans at the time owing to it and its interests in any other Extension of Credit); provided that (i) except in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans and rights to reimbursement under any LC Disbursement at the time owing to it or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund with respect to a Lender, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Administrative Agent)
shall not be less than $1,000,000, in the case of any assignment of a Loan or rights to reimbursement under an LC Disbursement, unless each of the Administrative Agent, the Issuing Bank and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consent (each such consent not to be unreasonably withheld or delayed), (ii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loan or rights to reimbursement under an LC Disbursement or the Commitment assigned, except that this clause (ii) shall not prohibit any Lender from assigning all or a portion of its rights and obligations among separate Commitments on a non pro rata basis, (iii) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Acceptance, together with a processing and recordation fee of $3,500, and the Eligible Assignee, if it shall not be a
Lender, shall deliver to the Administrative Agent an Administrative Questionnaire and (iv) such Lender has notified the Borrower of such assignment. Subject to 

63

acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Acceptance, the Eligible Assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.15, 2.16, 2.17 and 10.3. Any assignment or transfer
by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this
Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section.

             (c)   The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in New York, New York a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable
prior notice.

             (d)   Any Lender may, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans or rights to reimbursement under an LC Disbursement owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent, the Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or
instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver with respect to the following to the extent affecting such Participant: (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the date fixed for any payment of any principal of, or interest on, any Loan or interest thereon or any fees hereunder or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date for the termination or
reduction of any Commitment, without the written consent of each Lender affected thereby,  (iv) change Section 2.17(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) change any of the provisions of this Section or the definition 

64

of “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination  or grant any consent hereunder, without the consent of each Lender; (vi) release any guarantor or limit the liability of any such guarantor under any guaranty agreement without the written consent of each Lender except to the extent such release is expressly provided under the terms of such guaranty agreement; or (vii) release all or substantially all collateral (if any) securing any of the Obligations. Subject to paragraph (e) of this Section, the Borrower agrees that each Participant shall be entitled
to the benefits of Sections 2.15, 2.16, and 2.17 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.7 as though it were a Lender, provided such Participant agrees to be subject to Section 10.7 as though it were a Lender.

             (e)   Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPV”), identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Loan that such Granting initial Lender would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided, that (i) nothing herein shall constitute a commitment by any SPV to make any Loan and (ii) if an SPV elects not to exercise such option or otherwise fails to provide all or any part of any Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof. The making of a Loan by an SPV hereunder shall utilize the Commitment of the Granting
Lender to the same extent, and as if such Loan were made by such Granting Lender. Each party hereto hereby agrees that no SPV shall be liable for any indemnity or similar payment obligation under this Agreement (it being understood and agreed that the Granting Lender shall remain responsible for all of its obligations hereunder and shall protect and indemnify the Borrower, the Administrative Agent and the other Lenders for all liabilities, costs and expenses resulting from the acts and omissions of the SPV). 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 commercial paper or other senior indebtedness of any SPV, it will not institute against, or join any other person in instituting against, such SPV any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings
under the laws of the United States or any State. Notwithstanding anything to the contrary in this Section 10.4, any SPV may (i) with notice to, but without the prior written consent of, the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loans to the Granting Lender or to any financial institutions (consented to by the Borrower and the Administrative Agent) providing liquidity and/or credit support to or for the account of such SPV to support the funding or maintenance of Loans and (ii) disclose any non-public information relating to the Loans on a confidential basis in the manner set forth in Section 10.11.

             (f)   A Participant shall not be entitled to receive any greater payment under Section 2.15 and Section 2.17 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.17 unless the 

65

Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.17(e) as though it were a Lender. 

             (g)   Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

SECTION 10.5. Governing Law; Jurisdiction; Consent to Service of Process.

             (a)   This Agreement and the other Loan Documents shall be construed in accordance with and be governed by the law (without giving effect to the conflict of law principles thereof) of the State of  New York. 

             (b)   The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the United States District Court of the Southern District of New York, and of the Supreme Court of the State of New York sitting in New York County and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or any other Loan Document or the transactions contemplated hereby or thereby, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York state court or, to the extent permitted by applicable law, such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding
shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or any other Loan Document shall affect any right that the Administrative Agent  or any Lender may otherwise have to bring any action or proceeding  relating  to this Agreement or any other Loan Document against the Borrower or its properties in the courts of any jurisdiction.

             (c)   The Borrower irrevocably and unconditionally waives any objection which it may now or hereafter have to the laying of venue of any such suit, action or proceeding described in paragraph (b) of this Section and brought in any court referred to in paragraph (b) of this Section. Each of the parties hereto irrevocably waives, to the fullest extent permitted by applicable law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

             (d)   Each party to this Agreement irrevocably consents to the service of process in the manner provided for notices in Section 10.1. Nothing in this Agreement or in any other Loan Document will affect the right of any party hereto to serve process in any other manner permitted by law.

SECTION 10.6. WAIVER OF JURY TRIAL. 

             EACH PARTY HERETO IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF THIS 

66

AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES
HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

SECTION 10.7. Right of Setoff. 

             In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, each Lender shall have the right, at any time or from time to time upon the occurrence and during the continuance of an Event of Default, without prior notice to the Borrower, any such notice being expressly waived by the Borrower to the extent permitted by applicable law, to set off and apply against all deposits (general or special, time or demand, provisional or final) of the Borrower at any time held or other obligations at any time owing by such Lender to or for the credit or the account of the Borrower against any and all Obligations held by such Lender irrespective of whether such Lender shall have made demand hereunder and although such Obligations may be unmatured. Each Lender agrees to notify promptly the Administrative Agent and the Borrower after
any such setoff and any application made by such Lender; provided, that the failure to give such notice shall not affect the validity of such setoff and application. 

SECTION 10.8. Counterparts; Integration. 

             This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts (including by facsimile), and all of said counterparts taken together shall be deemed to constitute one and the same instrument. This Agreement, the Fee Letter, the other Loan Documents and the Administrative Agent Fee Letter constitute the entire agreement among the parties hereto and thereto regarding the subject matters hereof and thereof and supersede all prior agreements and understandings, oral or written, regarding such subject matters.

SECTION 10.9. Survival. 

             All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid and so long 

67

as the Commitments have not expired or terminated. The
provisions of Sections 2.15, 2.16, 2.17, and 10.3 and Article X shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Commitments or the termination of this Agreement or any provision hereof. All representations and warranties made herein, in the certificates, reports, notices, and other documents delivered pursuant to this Agreement shall survive the execution and delivery of this Agreement and the other Loan Documents, and the making of the Loans.

SECTION 10.10. Severability. 

             Any provision of this Agreement or any other Loan Document held to be illegal, invalid or unenforceable in any jurisdiction, shall, as to such jurisdiction, be ineffective to the extent of such illegality, invalidity or unenforceability without affecting the legality, validity or enforceability of  the remaining provisions hereof or thereof; and the illegality, invalidity or unenforceability of a particular provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

SECTION 10.11. Confidentiality. 

             Each of the Administrative Agent, the Issuing Bank and each Lender agrees to take normal and reasonable precautions to maintain the confidentiality of any information designated in writing as confidential and provided to it by the Borrower or any Subsidiary of the Borrower, except that unless otherwise agreed to in writing by such Lender, such information may be disclosed (i) to its Affiliates, to other Lenders and their respective Affiliates and to any actual or prospective assignee or Participant (provided that each such Person shall agree to be bound by the confidentiality provision of this Section 10.11) and any other Related Party of the Administrative Agent or any such
Lender, including without limitation accountants, legal counsel and other advisors, (ii) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (iii) to the extent requested by  any regulatory agency or authority, (iv) to the extent that such information becomes publicly available other than as a result of a breach of this Section, or which becomes available to the Administrative Agent, any Lender or any Related Party of any of the foregoing on a nonconfidential basis from a source other than the Borrower, (v) in connection with the exercise of any  remedy hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, or (vi) with the consent of the Borrower. Any Person required to maintain the confidentiality of any information as provided for in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same
degree of care to maintain the confidentiality of such information as such Person would accord its own confidential information.

SECTION 10.12. Waiver of Effect of Corporate Seal. 

             The Borrower represents and warrants that it is not required to affix its corporate seal to this Agreement or any other Loan Document pursuant to any requirement of law or regulation, and waives any shortening of the statute of limitations that may result from not affixing the corporate seal to this Agreement or such other Loan Documents.

ENVIRONMENTAL MATTERS

Clean Air Act Section 114 Letter. The United States Environmental Protection Agency (“USEPA”) has initiated investigation and enforcement actions against a number of electric utilities regarding the interpretation of routine maintenance and major modification of a facility which could trigger the applicability of New Source Performance Standards under the Clean Air Act. The Borrower, and one of its affiliates, has received a Section 114 letter from the USEPA on or about the third quarter of 2000 requiring it to provide records and information relevant to the operation and maintenance of ten electric generating facilities. The Borrower, and one of its affiliates, responded with the information requested. EPA has not yet responded to these submittals. While the Borrower, and one of its affiliates, cannot predict the outcome of this matter any future enforcement action settlement could result in material capital
expenditures or operating costs which may not be recouped by rate increases. For further information see “Environmental Issues” in the Allegheny Energy, Inc. Forms 10-K and 10-K/A filed on April 1, 2002 and April 9, 2002, respectively.

NOx Compliance. In response to an EPA NOx SIP call rule, the Borrower, and one of its affiliates, may be required to make significant reductions in its NOx emissions before May 2003 in Pennsylvania and Maryland and May 2004 in West Virginia. These reductions would require significant capital expenditures. For further information see “Environmental Issues” in the Allegheny Energy, Inc. Forms 10-K and 10-K/A filed on April 1, 2002 and April 9, 2002, respectively.

Mercury. USEPA has announced  plans to regulate mercury emissions from electric generating facilities in conjunction with, or shortly after, they complete further studies on the issue. The Borrower, and one of its affiliates, could be subject to additional emission control requirements on or before 2008, which could result in significant capital expenditures and operating costs.

Facility Operations and Releases. The Borrower, and one of its affiliates, owns and operates a number of active generation facilities with active coal combustion by-product disposal sites and processing operations, sedimentation ponds, coal piles, storage tanks (above and below ground), and other ancillary equipment necessary for operations. Some of these units have been owned or operated for many years and releases from some of these units may have occurred. the Borrower, and one of its affiliates, projects the need to site new disposal facilities within the next ten years which will involve significant capital expenditures and operating costs.

Open Consent Orders/Decrees. The Borrower is subject to two open consent orders: (i) Harrison Power Station Stormwater Consent Order (WVDEP, January 21, 2000, Order No. 4495), final evaluation November 13, 2003; and  (ii) R. Paul Smith Power Station (MDE, July 20, 1992) particulate testing for Unit 4, annually, and particulate testing for Unit 3, biannually.

Pleasants Power Station Stack Replacement. In order to comply with SO2 and particulate matter regulations and to maintain proper station operations the Borrower, and one of its affiliates, is conducting an engineering study for the construction of a new stack. Implementation of study results could result in significant capital expenditures and operating costs.

enhancement (the “Reference Ratings”) as follows:

      Rating		Applicable Rating

      Level

ARTICLE II
AMOUNT AND TERMS OF THE
COMMITMENTS

SECTION 2.1. General Description of
  Facility.

             Subject
to and upon the terms and conditions herein set forth, (i) the Lenders hereby
establish in favor of the Borrowers a revolving credit facility pursuant to
which the Lenders severally agree (to the extent of each Lender’s Commitment) to
make Loans to (x) AESC in an amount not to exceed the aggregate Commitments in
accordance with Section 2.2, and (y) AGC in an amount not to exceed $100,000,000
in accordance with Section 2.2; (ii) the Issuing Bank agrees to issue Letters of
Credit in accordance with Section 2.20; and (iii) each Lender agrees to purchase
a participation interest in the Letters of Credit pursuant to the terms and
conditions hereof; provided, that in no event shall the aggregate
principal amount of all outstanding Loans and the LC Exposure exceed at any time
the Aggregate Commitments in effect at such time.

SECTION 2.2. Loans. 

             Subject
to the terms and conditions set forth herein, each Lender severally agrees (to
the extent of such Lender’s Commitment) to make Loans to the Borrowers, ratably
in proportion to its Pro Rata Share, from the date hereof until the Termination
Date, (i) with respect to Loans made to AGC only, in an aggregate principal
amount not exceeding such Lender’s Pro Rata Share of $100,000,000 (the
“AGC Commitment Limit”) and (ii) with respect to Loans made to
AESC, in an aggregate principal amount not exceeding such Lender’s Commitment.
AESC and 

20

AGC shall be entitled to borrow, prepay and reborrow Loans in
accordance with the terms and conditions of this Agreement; provided, that
neither Borrower may borrow or reborrow if a Default or Event of Default has
occurred and is continuing. At no time shall the aggregate Extensions of Credit
exceed the Aggregate Commitments.

SECTION 2.3. Procedure for Borrowings.
  

             The
applicable Borrower shall give the Administrative Agent written notice (or
telephonic notice promptly confirmed in writing) of each Borrowing substantially
in the form of Exhibit 2.3 attached hereto (a “Notice of
Borrowing”) (x) by 11:00 a.m. on the requested date of a Base Rate
Borrowing and (y) by 11:00 a.m. three Business Days prior to the requested date
of a Eurodollar Borrowing. Each Notice of Borrowing shall be irrevocable and
shall specify: (i) the aggregate principal amount of such Borrowing, (ii) the
date of such Borrowing (which shall be a Business Day), (iii) the Type of Loan
comprising such Borrowing and (iv) in the case of a Eurodollar Borrowing, the
duration of the initial Interest Period applicable thereto (subject to the
provisions of the definition of Interest Period). Each Borrowing shall consist
entirely of Base Rate Loans or Eurodollar Loans, as the applicable Borrower may
request, until such Borrower elects a different interest rate option under
Section 2.5. The aggregate principal amount of each Eurodollar Borrowing shall
be not less than $5,000,000 or a larger multiple of $1,000,000, and the
aggregate principal amount of each Base Rate Borrowing shall not be less than
$1,000,000 or a larger multiple of $100,000. Promptly following the receipt of
the Notice of Borrowing in accordance herewith, the Administrative Agent shall
advise each Lender of the details thereof and the amount of such Lender’s Loan
to be made as part of the requested Borrowing.

SECTION 2.4. Funding of
  Borrowings.

             (a)   Each
Lender will make available the Loan to be made by it hereunder on the proposed
date thereof by wire transfer in immediately available funds by 11:00 a.m. in
the case of a Eurodollar Loan, or by 1:00 p.m. in the case of a Base Rate Loan,
to the Administrative Agent at the Payment Office. If by (A) 5:00 p.m. on the
Business Day preceding such proposed date in the case of a Eurodollar Loan or
(B) 11:00 a.m. on such proposed date in the case of a Base Rate Loan, the
applicable Borrower has met all of the conditions precedent, set forth in
Sections 3.1 and 3.2 of the Agreement, the Administrative Agent will make such
Loans available to such Borrower by initiating a wire transfer by 12:00 noon in
the case of a Eurodollar Loan, or by 2:00 p.m. in the case of a Base Rate Loan,
on such proposed date to an account designated by such Borrower to the
Administrative Agent.

             (b)   Unless
the Administrative Agent shall have been notified by any Lender prior to (A)
5:00 p.m. one Business Day prior to the date of a Eurodollar Borrowing or (B)
12:00 noon on the date of a Base Rate Borrowing in which such Lender is
participating that such Lender will not make available to the Administrative
Agent such Lender’s share of such Borrowing, the Administrative Agent may assume
that such Lender has made such amount available to the Administrative Agent on
such date, and the Administrative Agent, in reliance on such assumption,
may make available to the applicable Borrower on such
date a corresponding amount. If such corresponding amount is not in fact made
available to the Administrative Agent by such Lender on the date of such
Borrowing, the Administrative Agent shall be entitled to recover such
corresponding amount on demand from such Lender together with interest at the 

21

Federal Funds Rate for up to two days and thereafter at the rate specified for
such Borrowing. If such Lender does not pay such corresponding amount forthwith
upon the Administrative Agent’s demand therefor, the Administrative Agent shall
promptly notify the applicable Borrower, and such Borrower shall immediately pay
such corresponding amount to the Administrative Agent together with interest at
the rate specified for such Borrowing. Nothing in this subsection shall be
deemed to relieve any Lender from its obligation to fund its Pro Rata Share of
any Borrowing hereunder or to prejudice any rights which any Borrower may have
against any Lender as a result of any default by such Lender
hereunder.

             (c)   All
Borrowings shall be made by the Lenders on the basis of their respective Pro
Rata Shares. No Lender shall be responsible for any default by any other Lender
in its obligations hereunder, and each Lender shall be obligated to make its
Loans provided to be made by it hereunder, regardless of the failure of any
other Lender to make its Loans hereunder.

SECTION 2.5. Interest
  Elections.

             (a)   Each
Borrowing initially shall be of the Type specified in the Notice of Borrowing,
and in the case of a Eurodollar Borrowing, shall have an initial Interest Period
as specified in such Notice of Borrowing. Thereafter, the applicable Borrower
may elect to convert such Borrowing into a different Type or to continue such
Borrowing, and in the case of a Eurodollar Borrowing, may elect Interest Periods
therefor, all as provided in this Section. Such Borrower may elect different
options with respect to different portions of the affected Borrowing, in which
case each such portion shall be allocated ratably among the Lenders holding
Loans comprising such Borrowing, and the Loans comprising each such portion
shall be considered a separate Borrowing. At no time shall the total number of
Eurodollar Borrowings outstanding exceed four. 

             (b)   To
make an election pursuant to this Section, the applicable Borrower shall give
the Administrative Agent prior written notice (or telephonic notice promptly
confirmed in writing) of each Borrowing (a “Notice of
Conversion/Continuation”) that is to be converted or continued, as the
case may be, (x) by 1:00 p.m. on the requested date of a conversion into a Base
Rate Borrowing and (y) by 11:00 a.m. three Business Days prior to a continuation
of or conversion into a Eurodollar Borrowing. Each such Notice of
Conversion/Continuation shall be irrevocable and shall specify (i) the Borrowing
to which such Notice of Continuation/Conversion applies and if different options
are being elected with respect to different portions thereof, the portions
thereof that are to be allocated to each resulting Borrowing (in which case the
information to be specified pursuant to clauses (iii) and (iv) shall be
specified for each resulting Borrowing); (ii) the effective date of the election
made pursuant to such Notice of Continuation/Conversion, which shall be a
Business Day, (iii) whether the resulting Borrowing is to be a Base Rate
Borrowing or a Eurodollar Borrowing; and (iv) if the resulting Borrowing is to
be a Eurodollar Borrowing, the Interest Period applicable thereto after giving
effect to such election, which shall be a period contemplated by the definition
of “Interest Period”. If any such Notice of Continuation/Conversion requests a
Eurodollar Borrowing but does not specify an Interest Period, the applicable
Borrower shall be deemed to have selected an Interest Period of one month. The
principal amount of any resulting Borrowing shall satisfy the minimum borrowing
amount for Eurodollar Borrowings and Base Rate Borrowings set forth in Section
2.3.

22

             (c)   If,
on the expiration of any Interest Period in respect of any Eurodollar Borrowing,
the applicable Borrower shall have failed to deliver a Notice of
Conversion/Continuation, then, unless such Borrowing is repaid as provided
herein, such Borrower shall be deemed to have elected to convert such Borrowing
to a Base Rate Borrowing. No Borrowing may be converted into, or continued as, a
Eurodollar Borrowing if a Default or an Event of Default has occurred and is
continuing, unless the Administrative Agent and each of the Lenders shall have
otherwise consented in writing. No conversion of any Eurodollar Loans shall be
permitted except on the last day of the Interest Period in respect thereof.

             (d)   Upon
receipt of any Notice of Conversion/Continuation, the Administrative Agent shall
promptly notify each Lender of the details thereof and of such Lender’s Pro Rata
Share of each resulting Borrowing.

SECTION 2.6. Changes of
  Commitments.

             (a)   All
Commitments hereunder shall terminate on the Termination Date.

             (b)   Upon
at least three Business Days’ prior written notice (or telephonic notice
promptly confirmed in writing) to the Administrative Agent (which notice shall
be irrevocable), AESC (x) may reduce the unused portion of the Commitments
in part or terminate such Commitments in whole and (y) may reduce the
unused portion of the AGC Commitment Limit in part or terminate such AGC
Commitment Limit in whole; provided, that in the case of any reduction of
the Commitments under clause (x), (i) any partial reduction shall apply to
reduce proportionately and permanently the Commitment of each Lender and (ii)
any partial reduction pursuant to this Section 2.6 shall be in an amount of at
least $5,000,000 and any larger multiple of $1,000,000. Any reduction in the
Aggregate Commitments under clause (x) shall result in a proportional reduction
in the LC Commitment. Once terminated, a Commitment or the AGC Commitment Limit,
as the case may be, may not be reinstated.

             (c)   Increase
of Commitments.

             (i)   Requests
  for Increase by Company. AESC may, for a period of 45 days after the date
  hereof, by notice to the Administrative Agent, propose that the aggregate
  amount of the Commitments be increased (each such proposed increase being a
  “Commitment Increase”), effective as of a date (the
  “Commitment Increase Date”) that shall be specified in such
  notice and that shall be prior to the Approved Termination Date; provided
  that 

             (A)   the
    proposed Commitment Increase in respect of the Commitment of either
    (i) any Increasing Lender or (ii) any Assuming Lender for each
    Commitment Increase Date shall be in the aggregate amount of $10,000,000 or
    a multiple of $1,000,000 in excess thereof, provided that the minimum
    amount of the Commitment of any Assuming Lender shall be
    $15,000,000,

             (B)   in
    no event shall the aggregate amount of the Commitments hereunder, and under
    the 3-Year credit agreement, dated as of the date hereof, among AESC, the
    Lenders named therein, Citibank, as administrative agent, and Bank One, as
    issuer of letters of credit, at any time exceed
$1,000,000,000,

23

             (C)   no
    Default shall have occurred and be continuing on such Commitment Increase
    Date or shall result from the proposed Commitment Increase,
and

             (D)   the
    representations and warranties contained in Article IV shall be correct
    on and as of the Commitment Increase Date as if made on and as of such
    date.

The Administrative Agent shall notify the Lenders of
a proposed Commitment Increase promptly upon its receipt of any notice from AESC
with respect to such proposed Commitment Increase. It shall be in each Lender’s
sole discretion whether to increase its Commitment hereunder in connection with
any proposed Commitment Increase. No later than ten Business Days (or such
longer period as AESC and the Administrative Agent shall agree) after its
receipt of AESC’s notice proposing a Commitment Increase, each Lender that is
willing to increase its Commitment hereunder (each such Lender being an
“Increasing Lender”) shall deliver to the Administrative Agent a
notice in which such Lender shall set forth the maximum increase in its
Commitment to which such Lender is willing to agree, and the Administrative
Agent shall promptly provide to the Company a copy of such Increasing Lender’s
notice. 

             (ii)   Acceptance
  of Commitment Increase by AESC. If agreement is reached prior to the
  relevant Commitment Increase Date with any Increasing Lenders and Assuming
  Lenders, if any, as to a Commitment Increase (the amount of which may be less
  than (subject to the limitation set forth in clause (i)(A) of this
  Section 2.6(c)) but not greater than that amount specified in the applicable
  notice from AESC), AESC shall deliver, no later than three Business Days prior
  to such Commitment Increase Date, a notice thereof in reasonable detail to the
  Administrative Agent (and the Administrative Agent shall give notice thereof
  to the Lenders, including any Assuming Lenders). The Assuming Lenders, if any,
  shall become Lenders hereunder as of such Commitment Increase Date, and the
  Commitments of any Increasing Lenders and such Assuming Lenders shall be
  increased as of such Commitment Increase Date; provided
that:

             (x)
    the Administrative Agent shall have received on or prior to 9:00 a.m.,
    New York City time, on such Commitment Increase Date a certificate of a duly
    authorized officer of AESC stating that each of the applicable conditions to
    such Commitment Increase set forth in this Section 2.6(e) has been
    satisfied;

             (y)
    with respect to each Assuming Lender, the Administrative Agent shall have
    received, on or prior to 9:00 a.m., New York City time, on such
    Commitment Increase Date, an appropriate Assumption Agreement in
    substantially the form of Exhibit E, duly executed by such Assuming Lender
    and AESC; and

             (z)
    each Increasing Lender shall have delivered to the Administrative Agent, on
    or prior to 9:00 a.m., New York City time, on such Commitment Increase
    Date, confirmation in writing satisfactory to the Administrative Agent as to
    its increased Commitment, with a copy of such confirmation to
    AESC.

24

             (iii)   Recordation.
    Upon receipt by the Administrative Agent of confirmation from a Lender that
    it is increasing its Commitment hereunder, together with the certificate
    referred to in clause (ii)(x) above, the Administrative Agent shall (A)
    record the information contained therein in the appropriate records
    maintained by the Administrative Agent and (B) give prompt notice
    thereof to AESC. Upon receipt by the Administrative Agent of an Assumption
    Agreement executed by an Assuming Lender, together with the certificate
    referred to in clause (ii)(x) above, the Administrative Agent shall, if
    such Assumption Agreement has been completed and is in substantially the
    form of Exhibit C, (x) accept such Assumption Agreement,
    (y) record the information contained therein in the appropriate records
    maintained by the Administrative Agent and (z) give prompt notice
    thereof to AESC.

             (iv)   Adjustments
    of Borrowings upon Effectiveness of Increase. In the event that the
    Administrative Agent shall have received notice from AESC as to any
    agreement with respect to a Commitment Increase on or prior to the relevant
    Commitment Increase Date and the actions provided for in clauses (ii)(x)
    through (ii)(z) above shall have occurred by 9:00 a.m., New York City
    time, on such Commitment Increase Date, the Administrative Agent shall
    notify the Lenders (including any Assuming Lenders) of the occurrence of
    such Commitment Increase Date promptly on such date by facsimile
    transmission or electronic messaging system. On the date of such increase,
    the Borrowers shall each prepay their respective then outstanding Loans (if
    any) in full, and shall simultaneously borrow new Loans hereunder in an
    amount equal to such prepayment, so that, after giving effect thereto, the
    Loans of the respective Lenders to each Borrower are held ratably by the
    Lenders in accordance with their respective Commitments (after giving effect
    to such Commitment Increases). Prepayments made under this clause (iv) shall
    not be subject to the notice requirements of Section 2.9.

SECTION 2.7. Repayment of
  Loans.

             The
outstanding principal amount of all Loans shall be due and payable (together
with accrued and unpaid interest thereon) on the Termination Date.

SECTION 2.8. Evidence of
  Indebtedness.

             (a)   Each
Lender shall maintain in accordance with its usual practice appropriate records
evidencing the indebtedness of each Borrower to such Lender resulting from each
Loan made by such Lender from time to time, including the amounts of principal
and interest payable thereon and paid to such Lender from time to time under
this Agreement. The Administrative Agent shall maintain appropriate records in
which shall be recorded (i) the Commitment, (ii) the amount of each
Loan made thereunder by each Lender, the Type thereof and the Interest Period
applicable thereto, (iii) the date of each continuation thereof pursuant to
Section 2.5, (iv) the date of each conversion of all or a portion thereof to
another Type pursuant to Section 2.5, (v) the date and amount of any principal
or interest due and payable or to become due and payable from each Borrower to
each Lender hereunder in respect of such Loans and (vi) both the date and amount
of any sum received by the Administrative Agent hereunder from each Borrower in
respect of the Loans and each Lender’s Pro Rata Share thereof. The entries made
in such records shall be prima facie evidence of the existence and
amounts of the obligations of the applicable Borrower 

25

therein recorded;
provided, that the failure or delay of any Lender or the Administrative
Agent in maintaining or making entries into any such record or any error therein
shall not in any manner affect the obligation of the applicable Borrower to
repay the Loans (both principal and unpaid accrued interest) of such Lender in
accordance with the terms of this Agreement.

             (b)   At
the request of any Lender at any time, each Borrower agrees that it will execute
and deliver to such Lender a note, in form and substance mutually acceptable to
the Administrative Agent and the Borrower, payable to the order of such
Lender.

SECTION 2.9. Optional Prepayments.
  

             Each
Borrower shall have the right at any time and from time to time to prepay any
Borrowing, in whole or in part, without premium or penalty, by giving
irrevocable written notice (or telephonic notice promptly confirmed in writing)
to the Administrative Agent no later than (i) in the case of prepayment of any
Eurodollar Borrowing, 11:00 a.m. not less than three Business Days prior to any
such prepayment, and (ii) in the case of any prepayment of any Base Rate
Borrowing, by 11:00 a.m. on the date of such prepayment. Each such notice shall
be irrevocable and shall specify the proposed date of such prepayment and the
principal amount of each Borrowing or portion thereof to be prepaid. Upon
receipt of any such notice, the Administrative Agent shall promptly notify each
affected Lender of the contents thereof and of such Lender’s Pro Rata Share of
any such prepayment. If such notice is given, the aggregate amount specified in
such notice shall be due and payable on the date designated in such notice,
together with accrued interest to such date on the amount so prepaid in
accordance with Section 2.10; provided, that if a Eurodollar Borrowing is
prepaid on a date other than the last day of an Interest Period applicable
thereto, the applicable Borrower shall also pay all amounts required pursuant to
Section 2.16. Each partial prepayment of any Loan shall be in an amount that
would be permitted in the case of an advance of a Borrowing of the same Type
pursuant to Section 2.3. Each prepayment of a Borrowing shall be applied ratably
to the Loans comprising such Borrowing. 

SECTION 2.10. Interest on
  Loans.

             (a)   Each
Borrower shall pay interest on each Eurodollar Loan made to such Borrower at the
Adjusted LIBO Rate for the applicable Interest Period in effect for such Loan
plus the Applicable Margin in effect from time to time, and on each Base
Rate Loan at the Base Rate plus the Applicable Margin in effect from time
to time.

             (b)   While
an Event of Default has occurred and is continuing or after acceleration, at the
option of the Required Lenders, each Borrower shall pay interest (“Default
Interest”) with respect to all Eurodollar Loans made to such Borrower at
the rate otherwise applicable for the then current Interest Period plus an
additional 2% per annum until the last day of such Interest Period, and
thereafter, and with respect to all Base Rate Loans and all other Obligations
hereunder (other than Loans), at an all in rate in effect for Base Rate Loans,
plus an additional 2% per annum.

             (c)   Interest
on the principal amount of all Loans shall accrue from and including the date
such Loans are made to but excluding the date of any repayment thereof. Interest
on all 

26

outstanding Base Rate Loans shall be payable quarterly in arrears on the
last day of each fiscal quarter of AESC and on the Termination Date. Interest on
all outstanding Eurodollar Loans shall be payable on the last day of each
Interest Period applicable thereto, and on the Termination Date. Interest on any
Loan that is converted into a Loan of another Type or that is repaid or prepaid
shall be payable on the date of such conversion or on the date of any such
repayment or prepayment (on the amount repaid or prepaid) thereof. All Default
Interest shall be payable on demand.

             (d)   The
Administrative Agent shall determine each interest rate applicable to the Loans
hereunder and shall promptly notify AESC and the Lenders of such rate in writing
(or by telephone, promptly confirmed in writing). Any such determination shall
be conclusive and binding for all purposes, absent manifest error.

SECTION 2.11. Fees.

             (a)   AESC
shall pay to the Administrative Agent for its own account fees in the amounts
and at the times previously agreed upon by it in the Fee Letter. 

             (b)   AESC
shall pay to the Administrative Agent for the account of each Lender a facility
fee on each Lender’s Commitment, regardless of usage, from the date hereof in
the case of each initial Lender and from the effective date specified in the
Assignment and Acceptance pursuant to which it became a Lender in the case of
each other Lender payable at a rate per annum equal to the Facility Fee Rate,
until the Termination Date, payable on the last day of each March, June,
September and December and on the Termination Date.

             (c)   AESC
shall pay to the Administrative Agent for the account of each Lender a
utilization fee on each Lender’s Commitment at any time the aggregate amount of
all Extensions of Credit made hereunder exceeds 33% of the Aggregate
Commitments. The utilization fee shall be payable at a rate per annum equal to
the Utilization Fee Rate, payable on the last day of each March, June, September
and December and on the Termination Date.

             (d)   AESC
shall pay to the Administrative Agent for the account of each Lender (including,
without limitation the Issuing Bank in its capacity as Lender) the LC Fee on
each Lender’s Pro Rata Share of the average daily amount of the sum of the
undrawn stated amounts of all Letters of Credit outstanding on each such day,
from the date hereof until the later to occur of the Termination Date and the
date that no Letters of Credit are outstanding, payable on the last day of each
March, June, September and December and on the later to occur of the Termination
Date and the date that no Letters of Credit are outstanding. In addition, AESC
shall pay to the Administrative Agent for the account of the Issuing Bank (i) a
fronting fee on the average daily amount of the sum of the undrawn amounts of
all Letters of Credit outstanding on each such day, from the date hereof until
the later to occur of the Termination Date and the date that no Letters of
Credit are outstanding, payable on the last day of each March, June, September
and December and on such later date, at a rate equal to .15% per annum, and (ii)
such documentary and processing charges in connection with the issuance,
amendment, renewal or extension of, and each draw under, each Letter of Credit
in accordance with the Issuing Bank’s standard schedule for such charges as in
effect from time to time. 

27

SECTION 2.12. Computation of Interest and
  Fees.

             All
computations of interest and fees hereunder shall be made on the basis of a year
of 360 days for the actual number of days (including the first day but excluding
the last day) occurring in the period for which such interest or fees are
payable (to the extent computed on the basis of days elapsed). Each
determination by the Administrative Agent of an interest amount or fee hereunder
shall be made in good faith and, except for manifest error, shall be final,
conclusive and binding for all purposes. 

SECTION 2.13. Inability to Determine Interest
  Rates. 

             If
prior to the commencement of any Interest Period for any Eurodollar Borrowing,

             (i)   the
  Administrative Agent shall have determined (which determination shall be
  conclusive and binding upon each Borrower) that, by reason of circumstances
  affecting the relevant interbank market, adequate means do not exist for
  ascertaining LIBOR for such Interest Period, or 

             (ii)   the
  Administrative Agent shall have received notice from the Required Lenders that
  the Adjusted LIBO Rate does not adequately and fairly reflect the cost to such
  Lenders of making, funding or maintaining their Eurodollar Loans for such
  Interest Period,

the Administrative Agent shall give written notice
(or telephonic notice, promptly confirmed in writing) to AESC and to the Lenders
as soon as practicable thereafter. Until the Administrative Agent shall notify
AESC and the Lenders that the circumstances giving rise to such notice no longer
exist, (i) the obligations of the Lenders to make Eurodollar Loans or to
continue or convert outstanding Loans as or into Eurodollar Loans shall be
suspended and (ii) all such affected Loans shall be converted into Base Rate
Loans on the last day of the then current Interest Period applicable thereto
unless the applicable Borrower prepays such Loans in accordance with this
Agreement. Unless the applicable Borrower notifies the Administrative Agent at
least one Business Day before the date of any Eurodollar Borrowing for which a
Notice of Borrowing has previously been given that it elects not to borrow on
such date, then such Borrowing shall be made as a Base Rate Borrowing.

SECTION 2.14. Illegality.

             If
any Change in Law shall make it unlawful or impossible for any Lender to make,
maintain or fund any Eurodollar Loan and such Lender shall so notify the
Administrative Agent, the Administrative Agent shall promptly give notice
thereof to AESC and the other Lenders, whereupon until such Lender notifies the
Administrative Agent and AESC that the circumstances giving rise to such
suspension no longer exist, the obligation of such Lender to make Eurodollar
Loans, or to continue or convert outstanding Loans as or into Eurodollar Loans,
shall be suspended. In the case of the making of a Eurodollar Borrowing, such
Lender’s Loan shall be made as a Base Rate Loan as part of the same Borrowing
for the same Interest Period and if the affected Eurodollar Loan is then
outstanding, such Loan shall be converted to a Base Rate Loan either (i) on the
last day of the then current Interest Period applicable to such Eurodollar Loan if such
Lender may lawfully continue to maintain such Loan to such date or (ii)
immediately if 

28

such Lender shall determine that it may not lawfully continue to
maintain such Eurodollar Loan to such date. Notwithstanding the foregoing, the
affected Lender shall, prior to giving such notice to the Administrative Agent,
designate a different Applicable Lending Office if such designation would avoid
the need for giving such notice and if such designation would not otherwise be
disadvantageous to such Lender in the good faith exercise of its
discretion.

SECTION 2.15. Increased
  Costs.

             (a)   If
any Change in Law shall:

             (i)   impose,
  modify or deem applicable any reserve, special deposit or similar requirement
  that is not otherwise included in the determination of the Adjusted LIBO Rate
  hereunder against assets of, deposits with or for the account of, or credit
  extended by, any Lender or the Issuing Bank (each a “Claimant”)
  (except any such reserve requirement reflected in the Adjusted LIBO Rate); or
  

             (ii)   impose
  on any Claimant or the eurodollar interbank market any other condition
  affecting this Agreement or any Eurodollar Loans or other Extension of Credit
  made by such Claimant, excluding any change in Excluded Taxes;

and the result of the foregoing is to increase the
cost to such Claimant of making, converting into, continuing or maintaining a
Eurodollar Loan or other Extension of Credit or to increase the cost to such
Claimant or to reduce the amount received or receivable by such Claimant
hereunder (whether of principal, interest or any other amount), then the
applicable Borrower shall promptly pay, upon written notice from and demand by
such Claimant on such Borrower (with a copy of such notice and demand to the
Administrative Agent), to the Administrative Agent for the account of such
Claimant, within five Business Days after the date of such notice and demand,
additional amount or amounts sufficient to compensate such Claimant for such
additional costs incurred or reduction suffered. 

             (b)   If
any Claimant shall have determined that on or after the date of this Agreement
any Change in Law regarding capital requirements has or would have the effect of
reducing the rate of return on such Claimant’s capital (or on the capital of
such Claimant’s parent corporation) as a consequence of its obligations
hereunder to a level below that which such Claimant or such Claimant’s parent
corporation could have achieved but for such Change in Law (taking into
consideration such Claimant’s policies or the policies of such Claimant’s parent
corporation with respect to capital adequacy) then, from time to time, within
five Business Days after receipt by the applicable Borrower of written demand by
such Claimant (with a copy thereof to the Administrative Agent), such Borrower
shall pay to such Claimant such additional amounts as will compensate such
Claimant or such Claimant’s parent corporation for any such reduction suffered.

             (c)   A
certificate of a Claimant setting forth the amount or amounts necessary to
compensate such Claimant or such Claimant’s parent corporation, as the case may
be, specified in paragraph (a) or (b) of this Section shall be delivered to the
applicable Borrower (with a copy to the Administrative Agent) and shall be
conclusive, absent manifest error. Such Borrower shall pay any such Lender such
amount or amounts within 10 days after receipt thereof.

29

             (d)   Failure
or delay on the part of any Claimant to demand compensation pursuant to this
Section shall not constitute a waiver of such Claimant’s right to demand such
compensation.

SECTION 2.16. Funding Indemnity.
  

             In
the event of (i) the payment of any principal of a Eurodollar Loan other than on
the last day of the Interest Period applicable thereto (including as a result of
an Event of Default), (ii) the conversion or continuation of a Eurodollar Loan
other than on the last day of the Interest Period applicable thereto, (iii) the
failure by any Borrower to borrow, prepay, convert or continue any Eurodollar
Loan on the date specified in any applicable notice (regardless of whether such
notice is withdrawn or revoked), or (iv) any repayment of all or any portion of
any Eurodollar Borrowing other than on the last day of an Interest Period
therefor as a result of a request by the Borrower for a Commitment Increase
pursuant to Section 2.6(c) and a resulting adjustment of outstanding Borrowings
as among Lenders under paragraph (iv) of such Section, then, in any such event,
such Borrower shall compensate each Lender, within five Business Days after
written demand from such Lender, for any loss, cost or expense attributable to
such event. In the case of a Eurodollar Loan, such loss, cost or expense shall
be deemed to include an amount determined by such Lender to be the
excess, if any, of (A) the amount of interest that would have accrued on the
principal amount of such Eurodollar Loan if such event had not occurred at the
Adjusted LIBO Rate applicable to such Eurodollar Loan for the period from the
date of such event to the last day of the then current Interest Period therefor
(or in the case of a failure to borrow, convert or continue, for the period that
would have been the Interest Period for such Eurodollar Loan) over (B) the
amount of interest that would accrue on the principal amount of such Eurodollar
Loan for the same period if the Adjusted LIBO Rate were set on the date such
Eurodollar Loan was prepaid or converted or the date on which such Borrower
failed to borrow, convert or continue such Eurodollar Loan. A certificate as to
any additional amount payable under this Section 2.16 submitted to such Borrower
by any Lender (with a copy to the Administrative Agent) shall be conclusive,
absent manifest error.

SECTION 2.17. Taxes.

             (a)   Any
and all payments by or on account of any obligation of each Borrower hereunder
shall be made free and clear of and without deduction for any Indemnified Taxes
or Other Taxes; provided, that if any Borrower shall be required to
deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum
payable shall be increased as necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section) the Administrative Agent, the Issuing Bank or any Lender (as the
case may be) shall receive an amount equal to the sum it would have received had
no such deductions been made, (ii) such Borrower shall make such deductions and
(iii) such Borrower shall pay the full amount deducted to the relevant
Governmental Authority in accordance with applicable law.

             (b)   In
addition, each Borrower shall pay any Other Taxes to the relevant Governmental
Authority in accordance with applicable law.

             (c)   The
applicable Borrower shall indemnify the Administrative Agent, the Issuing Bank
and each Lender, within five Business Days after written demand therefor, for
the full 

30

amount of any Indemnified Taxes or Other Taxes paid by the
Administrative Agent, the Issuing Bank or such Lender, as the case may be, not
otherwise paid by such Borrower, on or with respect to any payment by or on
account of any obligation of such Borrower hereunder (including Indemnified
Taxes or Other Taxes imposed or asserted on or attributable to amounts payable
under this Section) and any penalties, interest and reasonable expenses arising
therefrom or with respect thereto, whether or not such Indemnified Taxes or
Other Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority. A certificate as to the amount of such payment or
liability delivered to the applicable Borrower by a Lender, the Issuing Bank or
by the Administrative Agent on its own behalf or on behalf of a Lender, shall be
conclusive absent manifest error.

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

             (e)   Any
Foreign Lender and if applicable, the Issuing Bank, that is entitled to an
exemption from or reduction of withholding tax under the Code or any treaty to
which the United States is a party, with respect to payments under this
Agreement shall deliver to AESC (with a copy to the Administrative Agent), at
the time or times prescribed by applicable law, such properly completed and
executed documentation prescribed by applicable law or reasonably requested by
any Borrower as will permit such payments to be made without withholding or at a
reduced rate. Without limiting the generality of the foregoing, each Foreign
Lender, or the Issuing Bank, agrees that it will deliver to the Administrative
Agent, the Issuing Bank and AESC (or in the case of a Participant, to the Lender
from which the related participation shall have been purchased), as appropriate,
two duly completed copies of (i) Internal Revenue Service Form W-8 ECI, or any
successor form thereto, certifying that the payments received from any Borrower
hereunder are effectively connected with such Foreign Lender’s or the Issuing
Bank’s conduct of a trade or business in the United States; or (ii) Internal
Revenue Service Form W-8 BEN, or any successor form thereto, certifying that
such Foreign Lender or the Issuing Bank is entitled to benefits under an income
tax treaty to which the United States is a party which reduces the rate of
withholding tax on payments of interest; or (iii) Internal Revenue Service Form
W-8 BEN, or any successor form prescribed by the Internal Revenue Service,
together with a certificate (A) establishing that the payment to the Foreign
Lender qualifies as “portfolio interest” exempt from U.S. withholding tax under
Code section 871(h) or 881(c), and (B) stating that (1) the Foreign Lender or
the Issuing Bank is not a bank for purposes of Code section 881(c)(3)(A), or the
obligation of any Borrower hereunder is not, with respect to such Foreign Lender
or the Issuing Bank, a loan agreement entered into in the ordinary course of its
trade or business, within the meaning of that section; (2)
the Foreign Lender or the Issuing Bank is not a 10% shareholder of either
Borrower within the meaning of Code section 871(h)(3) or 881(c)(3)(B); and (3)
the Foreign Lender or the Issuing Bank is not a controlled foreign corporation
that is related to either Borrower within the meaning of Code section
881(c)(3)(C); or (iv) such other Internal Revenue Service forms as may be
applicable to the Foreign Lender, including Forms W-8 IMY or W-8 EXP. Each such
Foreign Lender or the Issuing Bank shall deliver to AESC, the Issuing Bank and
the Administrative Agent such forms on or before the date that it becomes a
party to this Agreement (or in the case of a Participant, on or before the date
such Participant purchases the 

31

related participation). In addition, each such
Foreign Lender shall deliver such forms promptly upon the obsolescence or
invalidity of any form previously delivered by such Foreign Lender. Each such
Foreign Lender shall promptly notify AESC, the Issuing Bank and the
Administrative Agent at any time that it determines that it is no longer in a
position to provide any previously delivered certificate to AESC (or any other
form of certification adopted by the Internal Revenue Service for such purpose).

SECTION 2.18. Payments Generally; Pro Rata
  Treatment; Sharing of Setoffs. 

             (a)   Each
Borrower shall make each payment required to be made by it hereunder (whether of
principal, interest, fees or of amounts payable under Section 2.15, 2.16 or
2.17, or otherwise) prior to 12:00 noon, on the date when due, in immediately
available funds, free and clear of any defenses, rights of setoff, counterclaim,
or withholding or deduction of taxes. Any amounts received after such time on
any date may be deemed to have been received on the next succeeding Business Day
for purposes of calculating interest thereon. All such payments shall be made to
the Administrative Agent at the Payment Office, except that payments pursuant to
Sections 2.15, 2.16 and 2.17 and 11.3 shall be made directly to the Persons
entitled thereto. The Administrative Agent shall distribute any such payments
received by it for the account of any other Person to the appropriate recipient
promptly following receipt thereof. If any payment hereunder shall be due on a
day that is not a Business Day, the date for payment shall be extended to the
next succeeding Business Day, and, in the case of any payment accruing interest,
interest thereon shall be made payable for the period of such extension. All
payments hereunder shall be made in Dollars.

             (b)   If
at any time insufficient funds are received by and available to the
Administrative Agent to pay fully all amounts of principal, interest and fees
then due hereunder, such funds shall be applied (i) first, towards payment of
interest and fees then due hereunder, ratably among the parties entitled thereto
in accordance with the amounts of interest and fees then due to such parties,
and (ii) second, towards payment of principal ratably among the parties entitled
thereto in accordance with the amounts of principal then due to such
parties.

             (c)   If
any Lender shall, by exercising any right of setoff or counterclaim or
otherwise, obtain payment in respect of any principal of or interest on any of
its Loans or an account of a Borrower’s reimbursement obligations in respect of
such Lender’s participation in an LC Disbursement, that would result in such
Lender receiving payment of a greater proportion of the aggregate amount of its
Loans and accrued interest thereon than the proportion received by any other
Lender, then the Lender receiving such greater proportion shall purchase (for
cash at face value) participations in the Loans and such reimbursement
obligations of other Lenders to the extent necessary so that the benefit of all
such payments shall be shared by the Lenders ratably in accordance with the
aggregate amount of principal of and accrued interest on their respective Loans;
provided, that (i) if any such participations are purchased and all or
any portion of the payment giving rise thereto is recovered, such participations
shall be rescinded and the purchase price restored to the extent of such
recovery, without interest, and (ii) the provisions of this paragraph shall not
be construed to apply to any payment made by any Borrower pursuant to and in
accordance with the express terms of this Agreement or any payment obtained by a
Lender as consideration for the assignment of or sale of a participation in any
of its Loans to any assignee or participant, other than to any Borrower or any
Subsidiary or Affiliate thereof (as to which the 

32

provisions of this paragraph
shall apply). Each Borrower consents to the foregoing and agrees, to the extent
it may effectively do so under applicable law, that any Lender acquiring a
participation pursuant to the foregoing arrangements may exercise against such
Borrower rights of setoff and counterclaim with respect to such participation as
fully as if such Lender were a direct creditor of such Borrower in the amount of
such participation.

             (d)   Unless
the Administrative Agent shall have received notice from any Borrower prior to
the date on which any payment is due to the Administrative Agent for the account
of the Lenders hereunder that such Borrower will not make such payment, the
Administrative Agent may assume that such Borrower has made such payment on such
date in accordance herewith and may, in reliance upon such assumption,
distribute to the Lenders the amount or amounts due. In such event, if such
Borrower has not in fact made such payment, then each of the Lenders severally
agrees to repay to the Administrative Agent forthwith on demand the amount so
distributed to such Lender with interest thereon, for each day from and
including the date such amount is distributed to it to but excluding the date of
payment to the Administrative Agent, at the greater of the Federal Funds
Effective Rate and a rate determined by the Administrative Agent in accordance
with banking industry rules on interbank compensation.

             (e)   If
any Lender shall fail to make any payment required to be made by it pursuant to
Section 2.18(d) or 11.3(d), then the Administrative Agent may, in its discretion
(notwithstanding any contrary provision hereof), apply any amounts thereafter
received by the Administrative Agent for the account of such Lender to satisfy
such Lender’s obligations under such Sections until all such unsatisfied
obligations are fully paid.

SECTION 2.19. Mitigation of Obligations.
  

             If
any Lender requests compensation under Section 2.15, or if either Borrower is
required to pay any additional amount to any Lender or any Governmental
Authority for the account of any Lender pursuant to Section 2.17, then such
Lender shall use reasonable efforts to designate a different lending office for
funding or booking its Loans hereunder or to assign its rights and obligations
hereunder to another of its offices, branches or affiliates, if, in the sole
judgment of such Lender, such designation or assignment (i) would eliminate or
reduce amounts payable under Section 2.15 or Section 2.17, as the case may be,
in the future and (ii) would not subject such Lender to any unreimbursed cost or
expense and would not otherwise be disadvantageous to such Lender. The Borrowers
hereby agree to pay all costs and expenses incurred by any Lender in connection
with such designation or assignment.

SECTION 2.20. Letters of
  Credit.

             (a)   The
Issuing Bank, in reliance upon the agreements of the other Lenders pursuant to
Section 2.20(d), agrees to issue, at the request of either Borrower, Letters of
Credit for the account of such Borrower and to make LC Disbursements payable in
accordance with the terms and conditions of Letters of Credit issued hereunder,
all on the terms and conditions set forth herein; provided, that (i) each Letter
of Credit shall expire no later than the date that is five Business Days prior
to the Termination Date; (ii) each Letter of Credit shall be in a stated amount
no less than $100,000; (iii) no Borrower may request any Letter of Credit, if,
after giving effect to such issuance the aggregate LC Exposure would exceed the
LC Commitment; (iv) AGC 

33

may not request any Letter of Credit that would result
in the Extensions of Credit made to it to exceed the AGC Commitment Limit; and
(v) no Borrower may request any Letter of Credit that would cause the aggregate
amount of all Extensions of Credit to exceed the Aggregate Commitments. Upon the
issuance of each Letter of Credit each Lender shall be deemed to, and hereby
irrevocably and unconditionally agrees to, purchase from the Issuing Bank
without recourse a participation in such Letter of Credit equal to such Lender’s
Pro Rata Share of the aggregate amount available to be drawn under such Letter
of Credit. Each issuance of a Letter of Credit shall be deemed to utilize the
Commitment of each Lender by an amount equal to the amount of such
participation.

             (b)   To
request the issuance of a Letter of Credit (or any amendment, renewal or
extension of an outstanding Letter of Credit), the applicable Borrower shall
give the Issuing Bank and the Administrative Agent an irrevocable Request for
Issuance by delivering such Request for Issuance to both the Issuing Bank and
the Administrative Agent not later than 1:00 p.m. (Central time) one Business
Day prior to the requested date of such issuance (or amendment, renewal or
extension, as the case may be). In addition to the satisfaction of the
conditions in Article III (the satisfaction of which the Issuing Bank shall have
no duty to ascertain), the issuance of each Letter of Credit (or any amendment
that increases the amount of a Letter of Credit) will be subject to the further
conditions that such Letter of Credit shall be in such form and contain such
terms as the Issuing Bank shall approve and that the applicable Borrower shall
have executed and delivered to the Issuing Bank such application or
reimbursement agreement, and/or such other instruments and agreements relating
to such Letter of Credit, if any, as the Issuing Bank may have reasonably
requested. In the event of any conflict between the terms of any such
application, agreement or instrument and the terms of this Agreement, the terms
of this Agreement shall control. At the request of any Borrower, any Letter of
Credit may be issued designating a subsidiary of such Borrower as a nominal
account party in respect of such Letter of Credit, but no such designation shall
in any manner limit or impair, or relieve such Borrower of, the obligations of
such Borrower, hereunder or of AESC under Article VIII and in respect of such
Letter of Credit, it being understood and agreed that, as among the several
parties to this Agreement, the applicable Borrower shall at all times have all
of the rights and be subject to all of the obligations, duties and
responsibilities of an account party with respect to each letter of Credit
whether or not such Letter of Credit refers to such Borrower as the account
party with respect to such Letter of Credit.

             (c)   Unless
the Issuing Bank has received notice from the Administrative Agent on or before
1:00 p.m (Central time) on the requested date of such issuance (or amendment,
renewal or extension, as the case may be) directing the Issuing Bank not to
issue the Letter of Credit because such issuance (or amendment, renewal or
extension, as the case may be) is not then permitted hereunder because of the
limitations set forth in Section 2.20(a) or that one or more conditions
specified in Article III are not then satisfied, then, subject to the terms and
conditions of this Section 2.20, the Issuing Bank shall, on the requested date,
issue such Letter of Credit (or amendment, renewal or extension, as the case may
be) in accordance with the Issuing Bank’s usual and customary business
practices, and provide notice and a copy thereof to the Administrative
Agent.

             (d)   The
Issuing Bank shall examine all documents purporting to represent a demand for
payment under a Letter of Credit promptly following its receipt thereof. The
responsibility of 

34

the Issuing Bank to the applicable Borrower and each Lender
shall be only to determine that the documents (including each demand for
payment) delivered under each Letter of Credit in connection with such
presentment shall be in conformity in all material respects with such Letter of
Credit, and the Issuing Bank shall endeavor to exercise the same care in the
issuance and administration of the Letters of Credit as it does with respect to
letters of credit in which no participations are granted. The Issuing Bank shall
promptly notify the applicable Borrower and the Administrative Agent of each
demand for payment under a Letter of Credit and whether the Issuing Bank has
made or will make a LC Disbursement thereunder; provided, that any
failure to give or delay in giving such notice shall not relieve the applicable
Borrower of its obligation to reimburse the Issuing Bank and the Lenders with
respect to such LC Disbursement. Such Borrower shall be irrevocably and
unconditionally obligated to reimburse the Issuing Bank for any LC Disbursements
paid by the Issuing Bank in respect of such drawing, without presentment, demand
or other formalities of any kind. Unless such Borrower shall have notified the
Issuing Bank and the Administrative Agent prior to 10:00 a.m. (Central time) on
the Business Day immediately prior to the date on which such drawing is honored
that such Borrower intends to reimburse the Issuing Bank for the amount of such
drawing in funds other than from the proceeds of Loans, such Borrower shall be
deemed to have timely given a Notice of Borrowing to the Administrative Agent
requesting the Lenders to make a Base Rate Borrowing on the date on which such
drawing is honored in an exact amount due to the Issuing Bank; provided,
that for purposes solely of such Borrowing, the conditions precedents set forth
in Section 3.2 hereof shall not be applicable. The Administrative Agent shall
notify the Lenders of such Borrowing in accordance with Section 2.3, and each
Lender shall make the proceeds of its Base Rate Loan included in such Borrowing
available to the Administrative Agent for the account of the Issuing Bank in
accordance with Section 2.8. The proceeds of such Borrowing shall be applied
directly by the Administrative Agent to reimburse the Issuing Bank for such LC
Disbursement.

             (e)   If
for any reason a Base Rate Borrowing may not be (as determined in the sole
discretion of the Administrative Agent), or is not, made in accordance with the
foregoing provisions, then each applicable Lender (other than the Issuing Bank)
shall be obligated to fund the participation that such Lender purchased pursuant
to subsection (a) in an amount equal to its Pro Rata Share of such LC
Disbursement on and as of the date which such Base Rate Borrowing should have
occurred. Each Lender’s obligation to fund its participation shall be absolute
and unconditional and shall not be affected by any circumstance, including
without limitation (i) any setoff, counterclaim, recoupment, defense or other
right that such Lender or any other Person may have against any beneficiary of a
Letter of Credit, the Issuing Bank or any other Person for any reason
whatsoever, (ii) the existence of a Default or an Event of Default or the
termination of the Commitments, (iii) any adverse change in the condition
(financial or otherwise) of any Borrower or any of its Subsidiaries, (iv) any
breach of this Agreement by any Borrower or any other Lender, (v) any amendment,
renewal or extension of any Letter of Credit or (vi) any other circumstance,
happening or event whatsoever, whether or not similar to any of the foregoing.
On the date that such participation is required to be funded, each Lender shall
promptly transfer, in immediately available funds, the amount of its
participation to the Administrative Agent for the account of the Issuing Bank.
Whenever, at any time after the Issuing Bank has received from any such Lender
the funds for its participation in a LC Disbursement, the Issuing Bank (or the
Administrative Agent on its behalf) receives any payment on account thereof, the
Administrative Agent or the Issuing Bank, as the case may be, will distribute to
such Lender its Pro Rata Share of such payment; provided, that if such
payment is required to be returned for any reason to any 

35

Borrower making such
payment or to a trustee, receiver, liquidator, custodian or similar official in
any bankruptcy proceeding, such Lender will return to the Administrative Agent
or the Issuing Bank any portion thereof previously distributed by the
Administrative Agent or the Issuing Bank to it.

             (f)   To
the extent that any Lender shall fail to pay any amount required to be paid
pursuant to subsection (d) of this Section 2.20 on the due date therefor,
such Lender shall pay interest to the Issuing Bank (through the Administrative
Agent) on such amount from such due date to the date such payment is made at a
rate per annum equal to the Federal Funds Rate; provided,
that if such Lender shall fail to make such payment to the Issuing Bank within
three Business Days of such due date, then, retroactively to the due date, such
Lender shall be obligated to pay Default Interest on such amount.

             (g)   If
any Event of Default shall occur and be continuing, on the Business Day that any
Borrower receives notice from the Administrative Agent or the Required Lenders
demanding the deposit of cash collateral pursuant to this paragraph, such
Borrower shall deposit in an account with the Administrative Agent, in the name
of the Administrative Agent and for the benefit of the Issuing Bank and the
Lenders, an amount in cash equal to the LC Exposure as of such date plus any
accrued and unpaid fees thereon; provided, that the obligation to deposit
such cash collateral shall become effective immediately, and such deposit shall
become immediately due and payable, without demand or notice of any kind, upon
the occurrence of any Event of Default with respect to any Borrower described in
clause (g) or (h) of Section 9.1. Such deposit shall be held by the
Administrative Agent as collateral for the payment and performance of the
obligations of such Borrower under this Agreement. The Administrative Agent
shall have exclusive dominion and control, including the exclusive right of
withdrawal, over such account. Each Borrower agrees to execute any documents
and/or certificates to effectuate the intent of this paragraph. Other than any
interest earned on the investment of such deposits, which investments shall be
made at the option and sole discretion of the Administrative Agent and at the
Borrowers’ risk and expense, such deposits shall not bear interest. Interest and
profits, if any, on such investments shall accumulate in such account. Moneys in
such account shall applied by the Administrative Agent to reimburse the Issuing
Bank for LC Disbursements for which it had not been reimbursed and to the extent
so applied, shall be held for the satisfaction of the reimbursement obligations
of the applicable Borrower for the LC Exposure at such time or, if the maturity
of the Loans has been accelerated, with the consent of the Required Lenders, be
applied to satisfy other obligations of the applicable Borrower under this
Agreement. If any Borrower is required to provide an amount of cash collateral
hereunder as a result of the occurrence of an Event of Default, such amount (to
the extent not so applied as aforesaid) shall be returned to such Borrower with
three Business Days after all Events of Default have been cured or
waived.

             (h)   Promptly
following the end of each fiscal quarter, the Issuing Bank shall deliver
(through the Administrative Agent) to each Lender and the applicable Borrower a
report describing the aggregate Letters of Credit outstanding at the end of such
fiscal quarter. Upon the request of any Lender from time to time, the Issuing
Bank shall deliver to such Lender any other information reasonably requested by
such Lender with respect to each Letter of Credit then outstanding.

36

             (i)   The
Borrowers’ obligations to reimburse LC Disbursements hereunder shall be
absolute, unconditional and irrevocable and shall be performed strictly in
accordance with the terms of this Agreement under all circumstances whatsoever
and irrespective of any of the following circumstances:

             (i)   Any
  lack of validity or enforceability of any Letter of Credit or this
  Agreement;

             (ii)   The
  existence of any claim, set-off, defense or other right which any Borrower or
  any Lender or any Subsidiary or Affiliate of any Borrower or any Lender may
  have at any time against a beneficiary or any transferee of any Letter of
  Credit (or any Persons or entities for whom any such beneficiary or transferee
  may be acting), any Lender (including the Issuing Bank) or any other Person,
  whether in connection with this Agreement or the Letter of Credit or any
  document related hereto or thereto or any unrelated transaction;

             (iii)   Any
  draft or other document presented under a Letter of Credit proving to be
  forged, fraudulent or invalid in any respect or any statement therein being
  untrue or inaccurate in any respect;

             (iv)   Payment
  by the Issuing Bank under a Letter of Credit against presentation of a draft
  or other document to the Issuing Bank that does not comply with the terms of
  such Letter of Credit;

             (v)   Any
  error, omission, interruption or delay in transmission, dispatch or delivery
  of any message or advice, however transmitted, in connection with any Letter
  of Credit;

             (vi)   Any
  other event or circumstance whatsoever, whether or not similar to any of the
  foregoing, that might, but for the provisions of this Section, constitute a
  legal or equitable discharge of, or provide a right of setoff against, either
  Borrower’s obligations hereunder; or

             (vii)   The
  existence of a Default or an Event of Default.

             (j)   Each
Letter of Credit shall be subject to (i) either (as selected by the Issuing Bank
from time to time) (A) the Uniform Customs and Practices for Documentary Credits
(1993 Revision), International Chamber of Commerce Publication No. 500, as the
same may be amended from time to time, or (B) the International Standby
Practices 1998 (ISP98), International Chamber of Commerce Publication No. 590,
as the same may be amended from time to time, and (ii) to the extent not
inconsistent therewith, the governing law of this Agreement set forth in Section
11.5.

             (k)   Neither
the Administrative Agent, the Issuing Bank, the Lenders nor any Related Party of
any of the foregoing shall have any liability or responsibility by reason of or
in connection with the issuance or transfer of any Letter of Credit or any
payment or failure to make any payment thereunder (irrespective of any of the
circumstances referred to above), or any error, omission, interruption, loss or
delay in transmission or delivery of any draft, notice or 

37

other communication
under or relating to any Letter of Credit (including any document required to
make a drawing thereunder), any error in interpretation of technical terms or
any consequence arising from causes beyond the control of the Issuing Bank;
provided, that the foregoing shall not be construed to excuse the Issuing
Bank from liability to any Borrower to the extent of any direct damages (as
opposed to consequential damages, claims in respect of which are hereby waived
by the Borrower to the extent permitted by applicable law) suffered by such
Borrower that are caused by either (x) the Issuing Bank’s gross negligence or
willful misconduct (as finally determined by a court of competent jurisdiction)
when determining whether drafts or other documents presented under a Letter of
Credit comply with the terms thereof, or (y) the Issuing Bank’s failure to pay
under any Letter of Credit after the presentation to it of a request strictly
complying with the terms and conditions of such Letter of Credit. In furtherance
of the foregoing and without limiting the generality thereof, the parties agree
that, with respect to documents presented that appear on their face to be in
substantial compliance with the terms of a Letter of Credit, the Issuing Bank
may, in its sole discretion, either accept and make payment upon such documents
without responsibility for further investigation, regardless of any notice or
information to the contrary, or refuse to accept and make payment upon such
documents if such documents are not in strict compliance with the terms of such
Letter of Credit.

             (l)   AESC
hereby agrees to indemnify and hold harmless each Lender, the Issuing Bank and
the Administrative Agent, and their respective directors, officers, agents and
employees from and against any and all claims and damages, losses, liabilities,
costs or expenses which such Lender, the Issuing Bank or the Administrative
Agent may incur (or that may be claimed against such Lender, the Issuing Bank or
the Administrative Agent by any Person whatsoever) by reason of or in connection
with the issuance, execution and delivery or transfer of or payment or failure
to pay under any Letter of Credit or any actual or proposed use of any Letter of
Credit, including, without limitation, any claims, damages, losses, liabilities,
costs or expenses which the Issuing Bank may incur by reason of or in connection
with (i) the failure of any other Lender to fulfill or comply with its
obligations to the Issuing Bank hereunder (but nothing herein contained shall
affect any rights AESC may have against any defaulting Lender) or (ii) by
reason of or on account of the Issuing Bank issuing any Letter of Credit that
specifies that the term “Beneficiary” included therein includes any successor by
operation of law of the named Beneficiary, but which Letter of Credit does not
require that any drawing by any such successor Beneficiary be accompanied by a
copy of a legal document, satisfactory to the Issuing Bank, evidencing the
appointment of such successor Beneficiary; provided that AESC shall not
be required to indemnify any Lender, the Issuing Bank or the Administrative
Agent for any claims, damages, losses, liabilities, costs or expenses to the
extent, but only to the extent, caused by (x) the willful misconduct or gross
negligence of the Issuing Bank (as finally determined by a court of competent
jurisdiction) or (y) the Issuing Bank’s failure to pay under any Letter of
Credit after the presentation to it of a request strictly complying with the
terms and conditions of such Letter of Credit. Nothing in this Section 2.20(l)
is intended to limit the obligations of AESC under any other provision of this
Agreement.

             (m)   Each
Lender hereby agrees to indemnify, ratably in accordance with its Pro Rata
Share, the Issuing Bank, its affiliates and their respective directors,
officers, agents and employees (to the extent not reimbursed by AESC) against
any cost, expense (including reasonable counsel fees and disbursements), claim,
demand, action, loss or liability (except such as result from such indemnitees’
gross negligence or willful misconduct or the Issuing Bank’s 

38

failure to pay
under any Letter of Credit after the presentation to it of a request strictly
complying with the terms and conditions of such Letter of Credit) that such
Findemnitees may suffer or incur in connection with this Section 2.20 or any
action taken or omitted by such indemnitees hereunder.

SECTION 2.21. Extension of Termination
  Date

             (a)   If
the Approved Termination Date has been extended to the 364th day after the date
of this Agreement, as contemplated by the definition of “Approved
Termination Date,” then at least 45 but not more than 60 days prior to the then applicable Approved
Termination Date, AESC may, by delivering a written notice to the Administrative
Agent (with such notice being irrevocable), and subject to the conditions set
forth in this Section, request that the Approved Termination Date be extended
for a period of 364 days, commencing on the Approved Termination Date then in
effect. The Administrative Agent shall notify each Lender of such request
promptly upon its receipt of such notice and shall request that each Lender
respond to such request by notifying the Administrative Agent in writing of its
consent to (with such consent being irrevocable), or rejection of, the requested
extension no earlier than 30 but no later than 20 days preceding the then
applicable Termination Date (or if such day is not a Business Day, the next
preceding Business Day). The Agent shall notify AESC in writing, of the Lenders’
decisions no later than 15 days prior to such Approved Termination Date. If any
Lender shall not have consented to the requested extension within the time
period specified in the preceding sentence, such Lender shall be deemed to have
rejected such request. 

             (b)   Subject
to subsection (c) below, the extension requested under subsection (a) above
shall be effective on the Approved Termination Date (the “Extension
Date”) if (i) on such date no Default shall have occurred and be
continuing or would occur as a result of such extension, (ii) Lenders
having Commitments representing not less than 51% of the Commitments of all
Lenders shall have consented in writing to such extension as provided in
subsection (a) above (such Lenders, collectively, the “Consenting
Lenders”), and (iii) on or prior to the proposed Extension Date
shall have delivered to the Administrative Agent (A) a certificate of a
duly authorized officer of each Borrower, dated such date, as to the accuracy,
both before and after giving effect to such proposed extension, of the
representations and warranties set forth in Article IV and as to the
absence, both before and after giving effect to such proposed extension, of any
Default, (B) certified copies of all corporate and governmental approvals,
if any, required to be obtained by each Borrower in connection with such
extension and (C) an opinion or opinions of counsel to AESC as to such
matters as the Administrative Agent or any Lender, through the Administrative
Agent, may reasonably request.

             (c)   Subject
to satisfaction of the conditions set forth in subsection (b) above, the
Commitment of each Consenting Lender shall be extended for a period of 364 days
commencing on the Extension Date. The Commitment of any Lender that rejected or
was deemed to have rejected the Borrower’s request to extend the Termination
Date (such Lenders, collectively, the “Declining Lenders”) shall
automatically terminate on the Extension Date, and AESC shall repay on the
Extension Date in full on such date all Advances extended by such Declining
Lender and all other amounts payable to such Declining Lender under this
Agreement.

39

             (d)   If
the extension requested pursuant to 2.21(a) has been granted and the conditions
set forth in 2.21(b) have been met, AESC may, for a period of 45 days following
the Extension Date, accept Commitments from Eligible Assignees (each, a
“New Lender”) in an amount not greater than the sum of
(i) the Commitments of all Declining Lenders plus (ii) the aggregate
amount of all decreases in the Commitments of the Consenting Lenders.

             (e)   Each
New Lender shall deliver a signature page hereto indicating that it is bound by
the terms hereof and setting forth its Commitment hereunder. Such new signature
page shall constitute a part hereof upon acceptance by the Administrative
Agent.

             (f)   Each
Consenting Lender and each New Lender will be deemed to have consented to an
amendment that replaces all references in this Agreement to AESC’s audited
financial statements for the fiscal year ended December 31, 2001 (as such
references may be further amended) with references to AESC’s audited year-end
financial statements most recently delivered to the Lenders under this
Agreement.

               (a)   at
  the time of and immediately after giving effect to such Extension of Credit,

               (c)   the

             Each
Extension of Credit (as well as each submission of a request for an Extension of

applicable Borrower on the date thereof as to the matters specified in
paragraphs (a) and (b) of this Section 3.2.

             All

the Administrative Agent.

ARTICLE IV
REPRESENTATIONS AND
WARRANTIES

             Each
Borrower represents and warrants to the Administrative Agent, the Issuing Bank
and each Lender as follows:

SECTION 4.1. Existence; Power.
  

             Each
Borrower and each of its Subsidiaries (i) is duly organized, validly existing
and in good standing as a limited liability company or corporation under the
laws of the jurisdiction of its organization, (ii) has all requisite power and
authority to carry on its business as now conducted, and (iii) is duly qualified
to do business, and is in good standing, in each jurisdiction where such
qualification is required, except where a failure to be so qualified could not
reasonably be expected to result in a Material Adverse Effect. 

42

SECTION 4.2. Organizational Power;
  Authorization. 

             The
execution, delivery and performance by each Borrower of the Loan Documents are
within such Borrower’s organizational powers and have been duly authorized by
all necessary organizational, and if required, member action. This Agreement has
been duly executed and delivered by such Borrower, and constitutes a valid and
binding obligation of the Borrowers, enforceable against them in accordance with
its terms, except as may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, or similar laws affecting the enforcement of
creditors’ rights generally and by general principles of equity.

SECTION 4.3. Governmental Approvals; No
  Conflicts. 

             The
execution, delivery and performance by each Borrower of this Agreement, and of
the other Loan Documents to which it is a party (i) do not require any consent
or approval of, registration or filing with, or any action by, any Governmental
Authority, except those as have been obtained or made and are in full force and
effect, or where the failure to do so could not reasonably be expected to have a
Material Adverse Effect, (ii) will not violate any applicable law, rule or
regulation or the charter, certificate of formation, bylaws, limited liability
company agreement, or other organizational documents of any Borrower or any of
its Subsidiaries or any judgment, order or ruling of any Governmental Authority,
(iii) will not violate or result in a default under any indenture, material
agreement or other material instrument binding on any Borrower or any of its
Subsidiaries or any of its assets or give rise to a right thereunder to require any
payment to be made by any Borrower or any of its Subsidiaries and (iv) will not
result in the creation or imposition of any Lien on any asset of any Borrower or
any of its Subsidiaries.

SECTION 4.4. Financial Statements.
  

             AESC
has furnished to each Lender the audited consolidated balance sheet of AESC and
its Subsidiaries as of December 31, 2000 and December 31, 2001 and the related
consolidated statements of income, shareholders’ equity and cash flows for the
fiscal year then ended audited by PricewaterhouseCoopers. Such financial
statements fairly present the consolidated financial condition of AESC and its
Subsidiaries as of such dates and the consolidated results of operations for
such periods in conformity with GAAP consistently applied, subject to year-end
audit adjustments. Since December 31, 2001, there have been no changes with
respect to AESC and its Subsidiaries that have had or could reasonably be
expected to have, singly or in the aggregate, a Material Adverse Effect;
provided, that changes in AESC’s trading positions arising in the
ordinary course of business shall be viewed in the aggregate rather than on an
individual trading position basis.

SECTION 4.5. Litigation and Environmental
  Matters.

               (a)   No
  litigation, investigation or proceeding of or before any arbitrators or
  Governmental Authorities is pending against or, to the knowledge of any
  Borrower, threatened against or affecting AESC or any of its Subsidiaries (i)
  that would reasonably be expected to have a Material Adverse Effect or (ii)
  that in any manner draws into question the validity or enforceability of this
  Agreement or any other Loan Document.

  

43

               (b)   Except
  for the matters set forth on Schedule 4.5, neither Borrower nor any of its
  Subsidiaries (i) has failed to comply with any Environmental Law or to obtain,
  maintain or comply with any permit, license or other approval required under
  any Environmental Law, (ii) has incurred or, to the knowledge of any Borrower,
  otherwise become subject to any Environmental Liability, (iii) has received
  notice of any claim with respect to any Environmental Liability or (iv) knows
  of any potential claim for any Environmental Liability, in each case that
  could reasonably be expected to have a Material Adverse Effect.

SECTION 4.6. Compliance with Laws and
  Agreements. 

             Each
Borrower and each of its Subsidiaries is in compliance with (i) all applicable
laws, rules, regulations, judgments and orders of any Governmental Authority,
and (ii) all indentures, agreements or other instruments binding upon it or its
properties, except where noncompliance would not have a Material Adverse Effect.

SECTION 4.7. Investment Company Act, Etc.
  

             Neither
AESC nor any of its Subsidiaries is an “investment company” or is “controlled”
by an “investment company”, as such terms are defined in, or subject to
regulation under, the Investment Company Act of 1940, as amended. Neither
Borrower is a “holding company” as defined in, or subject to regulation under,
the Public Utility Holding Company Act of 1935, as amended
(“PUHCA”). Under PUHCA, neither Borrower is prohibited from
incurring the Indebtedness contemplated by this Agreement. Neither Borrower is
otherwise subject to any other regulatory scheme limiting its ability to incur
debt. The Subsidiaries of each Borrower are not restricted or prohibited by any
Requirement of Law from paying cash dividends or distributions to their
shareholders from retained earnings. To the extent that any Borrower and its
Subsidiaries is subject to regulation under the Federal Power Act, such Borrower
and its Subsidiaries have received all necessary approvals and made all
necessary filings thereunder in connection with the execution, delivery and
performance of this Agreement and the other Loan Documents.

SECTION 4.8. Taxes. 

             Each
Borrower and its Subsidiaries and each other Person the taxes for which such
Borrower or any Subsidiary could become liable have timely filed or caused to be
filed all Federal income tax returns and all other material tax returns that are
required to be filed by them, and have paid all taxes shown to be due and
payable on such returns or on any assessments made against it or its property
and all other taxes, fees or other charges imposed on it or any of its property
by any Governmental Authority, except (i) to the extent the failure to do so
would not have a Material Adverse Effect or (ii) where the same
are currently being contested in good faith by appropriate proceedings and for
which such Borrower or such Subsidiary, as the case may be, has set aside on its
books adequate reserves in accordance with GAAP. As of the date hereof, the
charges, accruals and reserves on the books of such Borrower and its
Subsidiaries in respect of such taxes are adequate, and no tax liabilities that
could be materially in excess of the amount so provided are
anticipated.

44

SECTION 4.9. Margin Regulations.
  

             None
of the proceeds of any of the Loans will be used for “purchasing” or “carrying”
any “margin stock” with the respective meanings of each of such terms under
Regulation U as now and from time to time hereafter in effect or for any purpose
that violates the provisions of the applicable Margin Regulations. Neither
Borrower nor any of its Subsidiaries is engaged principally, or as one of its
important activities, in the business of extending credit for the purpose of
purchasing or carrying any “margin stock”.

SECTION 4.10. ERISA. 

             No
ERISA Event has occurred or is reasonably expected to occur that, when taken
together with all other such ERISA Events for which liability is reasonably
expected to occur, could reasonably be expected to result in a Material Adverse
Effect. The present value of all accumulated benefit obligations under each Plan
(based on the assumptions used for purposes of Statement of Financial Standards
No. 87) did not, as of the date of the most recent financial statements
reflecting such amounts, exceed the fair market value of the assets of such Plan
by more than $10,000,000, and the present value of all accumulated benefit
obligations of all underfunded Plans (based on the assumptions used for purposes
of Statement of Financial Standards No. 87) did not, as of the date of the most
recent financial statements reflecting such amounts, exceed the fair market
value of the assets of all such underfunded Plans by more than
$10,000,000.

SECTION 4.11. Ownership of
  Property.

             (a)   Each
Borrower and its Subsidiaries has good title to, or valid leasehold interests
in, all of its real and personal property material to the operation of its
business, free and clear of any Liens except Liens permitted under Section
7.2.

             (b)   Each
Borrower and its Subsidiaries owns, or is licensed, or otherwise has the right,
to use, all patents, trademarks, service marks, tradenames, copyrights,
franchises, licenses, and other intellectual property material to its business,
and the use thereof by each Borrower and its Subsidiaries does not infringe on
the rights of any other Person, except for any such infringements that,
individually or in the aggregate, would not have a Material Adverse Effect.

SECTION 4.12. Disclosure.

             Each
Borrower has disclosed to the Lenders all matters known to it that could
reasonably be expected to result in a Material Adverse Effect. None of the
reports (including all reports that any Borrower is required to file with the
SEC), financial statements, certificates or other information furnished in
writing by or on behalf of any Borrower to the Administrative Agent or any
Lender, or to the best knowledge of any Borrower otherwise provided to the
Administrative Agent, the Issuing Bank or any Lender, in connection with the
negotiation of this Agreement or any other Loan Document or delivered hereunder
or thereunder (as modified or supplemented by any other information so
furnished) contains any material misstatement of fact or omits to state any
material fact necessary to make the statements therein, taken as a whole, in
light of the circumstances under which they were made, not
misleading,

45

SECTION 4.13. Labor Relations.
  

             There
are no strikes, lockouts or other material labor disputes or grievances against
either Borrower or any of its Subsidiaries, or, to either Borrower’s knowledge,
threatened against or affecting either Borrower or any of its Subsidiaries, and
no significant unfair labor practice, charges or grievances are pending against
either Borrower or any of its Subsidiaries, or to either Borrower’s knowledge,
threatened against any of them before any Governmental Authority that could
reasonably be expected to have a Material Adverse Effect. All payments due from
either Borrower or any of its Subsidiaries pursuant to the provisions of any
collective bargaining agreement have been paid or accrued as a liability on the books of such
Borrower or such Subsidiary, except where the failure to do so could not
reasonably be expected to have a Material Adverse Effect.

SECTION 4.14. Subsidiaries.
  

             Schedule
4.14 sets forth the name of, the ownership interest of each Borrower in, the
jurisdiction of incorporation or organization of, and the type of, each
Subsidiary of each Borrower as of the date hereof.

SECTION 4.15. Pari Passu with Other
  Unsubordinated Unsecured Debt.

Lenders under this Agreement and the other Loan Documents, and (ii) the due
and punctual performance of all covenants, agreements, obligations and
liabilities of AGC under or pursuant to this Agreement and the other Loan
Documents; (all the monetary and other obligations referred to in the preceding
clauses (i) and (ii) being collectively called the “Guarantied
Obligations”). AESC further agrees that the Guarantied Obligations may
be modified, extended or renewed, in whole or in part, without notice to or
further assent from it, and that it will remain bound upon its guaranty
notwithstanding any extension or renewal of any Guarantied Obligation, subject
to the provisions of Section 11.2.

SECTION 8.2. Guarantied Obligations Not
  Waived.

             To
the fullest extent permitted by applicable law, AESC waives presentment to,
demand of payment from and protest to AGC of any of the Guarantied Obligations,
and also waives notice of acceptance of its guaranty and notice of protest for
nonpayment. To the fullest extent permitted by applicable law, the obligations
of AESC under this Article VIII shall not be affected by (i) the failure of
the Administrative Agent, the Issuing Bank or any Lender to assert any claim or
demand or to enforce or exercise any right or remedy against either Borrower
under the provisions of this Agreement, any other Loan Document or otherwise,
(ii) any rescission, waiver, amendment or modification of, or any release
from any of the terms or provisions of, this Agreement, any other Loan Document
or any other agreement, or (iii) the failure to perfect any security
interest in, or the release of, any of the security held by or on behalf of the
Administrative Agent or any Lender.

SECTION 8.3. Guaranty of
  Payment.

             AESC
further agrees that its guaranty constitutes a guaranty of payment when due and
not of collection, and waives any right to require that any resort be had by the
Administrative 

56

Agent or any Lender to any of the security held for payment of
the Guarantied Obligations or to any balance of any deposit account or credit on
the books of the Administrative Agent or any Lender in favor of either Borrower
or any other Person.

SECTION 8.4. No Discharge or Diminishment of
  Guaranty.

             The
obligations of AESC under this Article VIII shall not be subject to any
reduction, limitation, impairment or termination for any reason (other than the
indefeasible payment in full in cash of the Guarantied Obligations), including
any claim of waiver, release, surrender, alteration or compromise of any of the
Guarantied Obligations, and shall not be subject to any defense or setoff,
counterclaim, recoupment or termination whatsoever by reason of the invalidity,
illegality or unenforceability of the Guarantied Obligations or otherwise.
Without limiting the generality of the foregoing, the obligations of AESC under
this Article VIII shall not be discharged or impaired or otherwise affected by
the failure of the Administrative Agent or any Lender to assert any claim or
demand or to enforce any remedy under this Agreement, any other Loan Document or
any other agreement, by any waiver or modification of any provision of any
thereof, by any default, failure or delay, willful or otherwise, in the
performance of the Guarantied Obligations, or by any other act or omission that
may or might in any manner or to any extent vary the risk of AESC or that would
otherwise operate as a discharge of a guarantor as a matter of law or equity
(other than the indefeasible payment in full in cash of all the Guarantied
Obligations).

SECTION 8.5. Defenses of AESC
  Waived.

             To
the fullest extent permitted by applicable law, AESC waives any defense based on
or arising out of any defense of AGC or the unenforceability of the Guarantied
Obligations or any part thereof from any cause, or the cessation from any cause
of the liability of AGC, other than the final and indefeasible payment in full
in cash of the Guarantied Obligations. The Administrative Agent and the Lenders
may, at their election, foreclose on any security held by one or more of them by
one or more judicial or nonjudicial sales, accept an assignment of any such
security in lieu of foreclosure, compromise or adjust any part of the Guarantied
Obligations, without affecting or impairing in any way the liability of AESC
under this Article VIII except to the extent the Guarantied Obligations have
been fully, finally and indefeasibly paid in cash. Pursuant to applicable law,
AESC waives any defense arising out of any such election even though such
election operates, pursuant to applicable law, to impair or to extinguish any
right of reimbursement or subrogation or other right or remedy of AESC against
AGC or any other guarantor, or any security.

SECTION 8.6.
Subordination.

             Upon
payment by AESC of any sums to the Administrative Agent, all rights of AESC
against AGC arising as a result thereof by way of right of subrogation,
contribution, reimbursement, indemnity or otherwise shall in all respects be
subordinate and junior in right of payment to the prior indefeasible payment in
full in cash of all the Guarantied Obligations. If any amount shall erroneously
be paid to AESC on account of (i) such subrogation, contribution, reimbursement,
indemnity or similar right or (ii) any such indebtedness, such amount shall be
held in trust for the benefit of the Administrative Agent and the Lenders and
shall forthwith be 

57

paid to the Administrative Agent to be credited against the
payment of the Guarantied Obligations, whether matured or unmatured, in
accordance with the terms of the Loan Documents.

SECTION 8.7.
Information.

             AESC
assumes all responsibility for being and keeping itself informed of the
financial condition and assets of AGC, and of all other circumstances bearing
upon the risk of nonpayment of the Guarantied Obligations and the nature, scope
and extent of the risks that AESC assumes and incurs hereunder, and agrees
neither the Administrative Agent nor any Lender will have any duty to advise
AESC of information known to it or any of them regarding such circumstances or
risks.

SECTION 8.8.
Termination.

             The
guaranties made hereunder (i) shall terminate when all the Guarantied
Obligations have been paid in full in cash and the Lenders and the Issuing Bank
have no further commitment to make Extensions of Credit under this Agreement and
(ii) shall continue to be effective or be reinstated, as the case may be,
if at any time payment, or any part thereof, of any Guarantied Obligation is
rescinded or must otherwise be restored by the Administrative Agent, the Issuing
Bank or any Lender upon the bankruptcy or reorganization of AGC. In connection
with the foregoing, the Administrative Agent shall execute and deliver to AESC
or AESC’s designee, at AESC’s expense, any documents or instruments that AESC
shall reasonably request from time to time to evidence such termination and
release.

ARTICLE IX

DEFAULT

SECTION 9.1. Events of
  Default.

             If
any of the following events (each an “Event of Default”) shall
occur:

  Borrower shall fail to pay any principal of any Loan (or the Guarantor shall
  fail to make any such payment in the Guarantied Obligations) or any

  fixed for prepayment or otherwise; or

  unremedied for a period of three Business Days; or

               (c)   any
  representation or warranty made or deemed made by or on behalf of any Borrower

  certificate, report, financial statement or other document submitted to the
  Administrative Agent, the Issuing Bank or the Lenders by any 

58

  Borrower or any representative of any Borrower pursuant to or in connection with this
  Agreement or any other Loan Document shall prove to be incorrect in any
  material respect when made or deemed made or submitted; or

               (d)   (i) AESC
  shall fail to observe or perform any covenant or agreement contained in
  Section 5.1, 5.2(a) or 5.3 (with respect to the existence of AESC and its
  Subsidiaries) or Article VI, VII or VIII (other than in respect of payment of
  an amount described in Section 8.1) or (ii) AGC shall fail to observe or

  for 30 days after the earlier of (i) any officer of the Borrower becomes aware
  of such failure, or (ii) notice thereof shall have been given to AESC by the
  Administrative Agent, or any Lender; or

               (f)   any
  Borrower or any Subsidiary of any Borrower (whether as primary obligor or as

  interest on any Material Indebtedness that is outstanding, when and as the
  same shall become due and payable (whether at scheduled maturity, required
  prepayment, acceleration, demand or otherwise), and such failure shall
  continue after the applicable grace period, if any, specified in the agreement
  or instrument evidencing such Indebtedness; or any other event shall occur or
  condition shall exist under any agreement or instrument relating to such
  Indebtedness and shall continue after the applicable grace period, if any,
  specified in such agreement or instrument, if the effect of such event or
  condition is to accelerate, or permit the acceleration of, the maturity of
  such Indebtedness; or any such Indebtedness shall be declared to be due and
  payable; or required to be prepaid or redeemed (other than by a regularly
  scheduled required prepayment or redemption), purchased or defeased, or any
  offer to prepay, redeem, purchase or defease such Indebtedness shall be
  required to be made, in each case prior to the stated maturity thereof;
  or

               (g)   any
  Borrower or any Subsidiary of any Borrower shall (i) commence a voluntary case

  any substantial part of its property, (ii) consent to the institution of, or
  fail to contest in a timely and appropriate manner, any proceeding or petition
  described in clause (i) of this Section, (iii) apply for or consent to the
  appointment of a custodian, trustee, receiver, liquidator or other similar
  official for such Borrower or any such Subsidiary of such Borrower or for a
  substantial part of its assets, (iv) file an answer admitting the material

  involuntary proceeding shall be commenced or an involuntary petition shall be
  filed seeking (i) liquidation, reorganization or other relief in respect of
  any Borrower or any Subsidiary of any Borrower or its debts, or any
  substantial part of its assets, under any federal, state or foreign
  bankruptcy, insolvency or other similar law now or hereafter in effect or (ii)
  the appointment of a custodian, trustee, receiver, liquidator or other similar
  official for any Borrower

  

59

  or any Subsidiary of any Borrower or for a
  substantial part of its assets, and in any such case, such proceeding or
  petition shall remain undismissed for a period of 60 days or an order or
  decree approving or ordering any of the foregoing shall be entered;
  or

               (i)   any

ARTICLE X
THE ADMINISTRATIVE
AGENT

SECTION 10.1. Appointment of Administrative
  Agent. 

             Each
Lender irrevocably appoints Citibank, N.A. as the Administrative Agent and
authorizes it to take such actions on its behalf and to exercise such powers as
are delegated to the Administrative Agent under this Agreement and the other
Loan Documents, together with all such actions and powers that are reasonably
incidental thereto. The Administrative Agent may perform any of its duties
hereunder by or through any one or more subagents appointed by the
Administrative Agent. The Administrative Agent and any such subagent may perform
any and all of its duties and exercise its rights and powers through their
respective Related Parties. The exculpatory provisions set forth in this Article
shall apply to any such subagent and the Related Parties of the Administrative
Agent and any such subagent and shall apply to their respective activities in
connection with the syndication of the credit facility provided for herein as
well as activities as Administrative Agent.

SECTION 10.2. Nature of Duties of
  Administrative Agent. 

             The
Administrative Agent shall not have any duties or obligations except those
expressly set forth in this Agreement and the other Loan Documents. Without
limiting the generality of the foregoing, (a) the Administrative Agent shall not
be subject to any fiduciary or other implied duties, regardless of whether a
Default or an Event of Default has occurred and is continuing, (b) the
Administrative Agent shall not have any duty to take any discretionary action or
exercise any discretionary powers, except those discretionary rights and powers
expressly contemplated by the Loan Documents that the Administrative Agent is
required to exercise in writing by the Required Lenders (or such other number or
percentage of the Lenders as shall be necessary under the circumstances as
provided in Section 11.2), and (c) except as expressly set forth in the Loan
Documents, the Administrative Agent shall not have any duty to disclose, and
shall not be liable for the failure to disclose, any information relating to any
Borrower or any of its Subsidiaries that is communicated to or obtained by the
Administrative Agent or any of its Affiliates in any capacity. The
Administrative Agent shall not be liable for any action taken or not taken by it
with the consent or at the request of the Required Lenders (or such other number
or percentage of the Lenders as shall be necessary under the circumstances as
provided in Section 11.2) or in the absence of its own gross negligence or
willful misconduct. The Administrative Agent shall not be deemed to have
knowledge of any Default or Event of Default unless and until written notice
thereof is given to the Administrative Agent by a Borrower, the Issuing Bank or
any Lender, and the Administrative Agent shall not be responsible for or have
any duty to ascertain or inquire into (i) any statement, warranty or
representation made in or in connection with any Loan Document, (ii) the
contents of any certificate, report or other document delivered hereunder or
thereunder or in connection herewith or therewith, (iii) the performance or
observance of any of the covenants, agreements, or other terms and conditions

61

set forth in any Loan Document, (iv) the validity, enforceability, effectiveness
or genuineness of any Loan Document or any other agreement, instrument or
document, or (v) the satisfaction of any condition set forth in Article III or
elsewhere in any Loan Document, other than to confirm receipt of items expressly
required to be delivered to the Administrative Agent.

SECTION 10.3. Lack of Reliance on the
  Administrative Agent. 

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

SECTION 10.4. Certain Rights of the
  Administrative Agent. 

             If
the Administrative Agent shall request instructions from the Required Lenders
with respect to any action or actions (including the failure to act) in
connection with this Agreement, the Administrative Agent shall be entitled to
refrain from such act or taking such act, unless and until it shall have
received instructions from such Lenders; and the Administrative Agent shall not
incur liability to any Person by reason of so refraining. Without limiting the
foregoing, no Lender shall have any right of action whatsoever against the
Administrative Agent as a result of the Administrative Agent acting or
refraining from acting hereunder in accordance with the instructions of the
Required Lenders where required by the terms of this Agreement.

SECTION 10.5. Reliance by Administrative
  Agent. 

             The
Administrative Agent shall be entitled to rely upon, and shall not incur any
liability for relying upon, any notice, request, certificate, consent,
statement, instrument, document or other writing believed by it to be genuine
and to have been signed, sent or made by the proper Person. The Administrative
Agent may also rely upon any statement made to it orally or by telephone and
believed by it in good faith to be made by the proper Person and shall not incur
any liability for relying thereon. The Administrative Agent may consult with
legal counsel (including counsel for the Borrowers), independent public
accountants and other experts selected by it and shall not be liable for any
action taken or not taken by it in good faith in accordance with the advice of
such counsel, accountants or experts.

SECTION 10.6. The Administrative Agent in its
  Individual Capacity. 

             The
bank serving as the Administrative Agent shall have the same rights and powers
under this Agreement and any other Loan Document in its capacity as a Lender as
any other Lender and may exercise or refrain from exercising the same as though
it were not the Administrative Agent; and the terms “Lenders” and “Required
Lenders”, or any similar terms shall, unless the context clearly otherwise
indicates, include the Administrative Agent in its individual capacity. The bank
acting as the Administrative Agent and its Affiliates may accept deposits from,
lend money to, and generally engage in any kind of business with any Borrower 

62

or
any Subsidiary or Affiliate of any Borrower as if it were not the Administrative
Agent hereunder.

SECTION 10.7. Successor Administrative
  Agent.

             (a)   The
Administrative Agent may resign at any time by giving notice thereof to the
Lenders, the Issuing Bank and AESC. Upon any such resignation, the Required
Lenders shall have the right to appoint a successor Administrative Agent,
subject to the approval by AESC provided that no Default or Event of
Default shall exist at such time. If no successor Administrative Agent shall
have been so appointed, and shall have accepted such appointment within 30 days
after the retiring Administrative Agent gives notice of resignation, then the
retiring Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, which shall be a commercial bank organized under the laws
of the United States of America or any state thereof or a bank which maintains
an office in the United States, having a combined capital and surplus of at
least $500,000,000.

             (b)   Upon
the acceptance of its appointment as the Administrative Agent hereunder by a
successor, such successor Administrative Agent shall thereupon succeed to and
become vested with all the rights, powers, privileges and duties of the retiring
Administrative Agent, and the retiring Administrative Agent shall be discharged
from its duties and obligations under this Agreement and the other Loan
Documents. If within 45 days after written notice is given of the retiring
Administrative Agent’s resignation under this Section 11.7 no successor
Administrative Agent shall have been appointed and shall have accepted such
appointment, then on such 45th day (i) the retiring Administrative Agent’s
resignation shall become effective, (ii) the retiring Administrative Agent shall
thereupon be discharged from its duties and obligations under the Loan Documents
and (iii) the Required Lenders shall thereafter perform all duties of the
retiring Administrative Agent under the Loan Documents until such time as the
Required Lenders appoint a successor Administrative Agent as provided above.
After any retiring Administrative Agent’s resignation hereunder, the provisions
of this Article X shall continue in effect for the benefit of such retiring
Administrative Agent and its representatives and agents in respect of any
actions taken or not taken by any of them while it was serving as the
Administrative Agent. 

SECTION 10.8. Authorization to Execute other
  Loan Documents. 

             Each
Lender and the Issuing Bank hereby authorizes the Administrative Agent to
execute on behalf of all Lenders and the Issuing Bank all Loan Documents other
than this Agreement and the Letters of Credit.

(including any facsimile, electronic transmission or any information on a
computer disk or similar medium which may be reduced to writing), or any
telephonic or other oral message or instruction (including, without limitation,
any oral waiver of any discrepancy with respect to any time), that such party
believes in good faith to have been received from an authorized officer,
employee or representative of any Borrower, and the Administrative Agent, the
Issuing Bank and the Lenders shall not be liable for any action taken in good
faith with respect to any writing, message or instruction from an unauthorized
person. Notwithstanding the foregoing, the Administrative Agent, the Issuing
Bank and the Lenders are not obligated to recognize the authenticity of any
request for the issuance of a Letter of Credit or to make a Borrowing hereunder
that is not evidenced to its satisfaction by a writing originally signed by a
person any Borrower has certified is authorized to act for such Borrower
hereunder or by a message or instruction authenticated to the satisfaction of
such Administrative Agent, the Issuing Bank or such Lender. 

SECTION 11.2. Waiver;
  Amendments.

             (a)   No
failure or delay by the Administrative Agent, the Issuing Bank or any Lender in
exercising any right or power hereunder or any other Loan Document, and no
course of dealing between any Borrower and the Administrative Agent, the Issuing Bank or any Lender,
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such right or power or any abandonment or discontinuance of steps to enforce
such right or power, preclude any other or further exercise thereof or the
exercise of any other right or power hereunder or thereunder. The rights and
remedies of the Administrative Agent, the Issuing Bank and the Lenders hereunder
and under the other Loan Documents are cumulative and are not exclusive of any
rights or remedies provided by law. No waiver of any provision of this Agreement
or any other Loan Document or consent to any departure by any Borrower therefrom
shall in any event be effective unless the same shall be permitted by paragraph
(b) of this Section, and then such waiver or consent shall be effective only in
the specific instance and for the purpose for which given. Without limiting the
generality of the foregoing, the making of a Loan shall not be construed as a
waiver of any Default or Event of Default, regardless of whether the
Administrative Agent, the Issuing Bank or any Lender may have had notice or
knowledge of such Default or Event of Default at the time.

             (b)   No
amendment or waiver of any provision of this Agreement or the other Loan
Documents, nor consent to any departure by any Borrower therefrom, shall in any
event be effective unless the same shall be in writing and signed by such
Borrower and the Required Lenders or such Borrower and the Administrative Agent
with the consent of the Required Lenders and then such waiver or consent shall
be effective only in the specific instance and for the specific purpose for
which given; provided, that no amendment or waiver shall: (i) increase
the Commitment of any Lender without the written consent of such Lender; (ii)
reduce the principal amount of any Loan or any reimbursement obligation in
respect of a Letter of Credit or reduce the rate of interest thereon, or reduce
any fees payable hereunder, without the written consent of each Lender and, if
applicable the Issuing Bank, affected thereby; (iii) postpone the date fixed for
any payment of any principal of, or interest on, any Loan or any reimbursement
obligation in respect of a Letter of Credit or interest thereon or any fees
hereunder or reduce the amount of, waive or excuse any such payment, or postpone
the scheduled date for the 

65

termination or reduction of any Commitment, or allow
a Letter of Credit to have an expiry date subsequent to the Termination Date
without the written consent of each Lender affected thereby, and, if applicable
the Issuing Bank; (iv) change Section 2.18 (b) or (c) in a manner that would
alter the pro rata sharing of payments required thereby, without the written
consent of each Lender and the Issuing Bank; (v) change any of the provisions of
this Section or the definition of “Required Lenders” or any other provision
hereof specifying the number or percentage of Lenders that are required to
waive, amend or modify any rights hereunder or make any determination or grant
any consent hereunder, without the consent of each Lender; (vi) release any
guarantor or limit the liability of any such guarantor under any guaranty
agreement, without the written consent of each Lender; (vii) release all or
substantially all collateral (if any) securing any of the Obligations without
the written consent of each Lender; (viii) affect the rights or duties of
the Issuing Bank under this Agreement without the written consent of the Issuing
Bank; provided further, that no such agreement shall amend, modify
or otherwise affect the rights, duties or obligations of the Administrative
Agent without the prior written consent of such Person; and provided further,
that any waiver of, or amendment to, the definition of “Change of Control”
shall require the consent of Lenders holding 66-2/3% or more of the aggregate
outstanding Commitments at such time, or, if the Commitments have been
terminated, the consent of Lenders holding 66-2/3% or more of the aggregate
outstanding Loans and obligations to participate in LC Disbursements at such
time. Notwithstanding the foregoing, any provision of this Agreement may be
amended by an agreement in writing entered into by the Borrowers, the Required
Lenders, the Issuing Bank and the Administrative Agent if (i) by the terms
of such agreement the Commitment of each Lender not consenting to the amendment
provided for therein shall terminate (but such Lender shall continue to be
entitled to the benefits of Sections 2.15, 2.16, and 2.17 and 11.3) upon
the effectiveness of such amendment and (ii) at the time such amendment
becomes effective, each Lender not consenting thereto receives payment in full
of principal of and interest accrued on each Loan made by it and all other
amounts owing to it or accrued for its account under this Agreement and is
released from its obligations hereunder.

SECTION 11.3. Expenses;
  Indemnification.

             (a)   AESC
shall pay (i) all reasonable, out-of-pocket costs and expenses of the
Administrative Agent and its Affiliates, including the reasonable fees, charges
and disbursements of counsel for the Administrative Agent and its Affiliates, in
connection with the preparation and administration of the Loan Documents and any
amendments, modifications or waivers thereof, and (ii) all out-of-pocket costs
and expenses (including, without limitation, the fees, charges and disbursements
of outside counsel and the allocated cost of inside counsel) incurred by the
Administrative Agent, the Issuing Bank or any Lender in connection with the
enforcement or protection of its rights after the occurrence of an Event of
Default in connection with this Agreement, including its rights under this
Section, or in connection with the Loans made,
including all such out-of-pocket expenses incurred during any workout,
restructuring or negotiations in respect of such Loans.

             (b)   AESC
shall indemnify the Administrative Agent, the Issuing Bank and each Lender, and
each Related Party of any of the foregoing (each, an “Indemnitee”)
against, and hold each of them harmless from, any and all losses, claims,
damages, costs, expenses (including reasonable fees, time charges and expenses
of attorneys for each Indemnitee) and liabilities of 

66

any Indemnitee arising out
of or relating to any litigation, investigation or other proceeding (regardless
of whether the Indemnitee is a party thereto and including any legal or other
expenses incurred in connection with the investigation or defense of any such
litigation or other proceeding) relating to or resulting from (i) the execution
or delivery of this Agreement or any other agreement or instrument contemplated
hereby, the performance by the parties hereto of their respective obligations
hereunder or the consummation of any of the transactions contemplated hereby,
(ii) any Loan or any actual or intended use of the proceeds therefrom,
(iii) the use by any Borrower or any Beneficiary of any Letter of Credit of
such Letter of Credit, (iv) any actual or alleged presence or release of
Hazardous Materials on or from any property owned by any Borrower or any
Subsidiary of any Borrower or any Environmental Liability related to any
Borrower or any Subsidiary of any Borrower, whether based on contract, tort or
any other theory and (iv) any claim against the Administrative Agent or the
Issuing Bank brought by a Lender or the Issuing Bank; provided, that AESC
shall not be obligated to indemnify any Indemnitee for any of the foregoing
arising out of such Indemnitee’s gross negligence or willful misconduct as
determined by a court of competent jurisdiction in a final and nonappealable
judgment. 

             (c)   AESC
shall pay, and hold the Administrative Agent, the Issuing Bank and each of the
Lenders harmless from and against, any and all present and future stamp,
documentary, and other similar taxes with respect to this Agreement and any
other Loan Documents, any collateral described therein, or any payments due
thereunder, and save the Administrative Agent and each Lender harmless from and
against any and all liabilities with respect to or resulting from any delay or
omission to pay such taxes.

             (d)   To
the extent that AESC fails to pay any amount required to be paid to the
Administrative Agent or the Issuing Bank under clauses (a), (b) or (c) hereof,
each Lender severally agrees to pay to the Administrative Agent, such Lender’s
Pro Rata Share (determined as of the time that the unreimbursed expense or
indemnity payment is sought) of such unpaid amount; provided, that the
unreimbursed expense or indemnified payment, claim, damage, liability or related
expense, as the case may be, was incurred by or asserted against the
Administrative Agent or the Issuing Bank in its capacity as such.

             (e)   To
the extent permitted by applicable law, AESC shall not assert, and hereby
waives, any claim against any Indemnitee, on any theory of liability, for
special, indirect, consequential or punitive damages (as opposed to actual or
direct damages) arising out of, in connection with or as a result of, this
Agreement or any agreement or instrument contemplated hereby, the transactions
contemplated therein, any Loan or the use of proceeds thereof.

             (f)   All
amounts due under this Section shall be payable promptly after written demand
therefor. 

SECTION 11.4. Successors and
  Assigns.

             (a)   The
provisions of this Agreement shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and assigns permitted hereby,
except that no Borrower may assign or otherwise transfer any of its rights or
obligations hereunder (other than to an assignee expressly permitted or not
restricted under Section 7.3 hereof) without the prior 

67

written consent of each
Lender (and any attempted assignment or transfer by the Borrower without such
consent shall be null and void). Nothing in this Agreement, expressed or
implied, shall be construed to confer upon any Person (other than the parties
hereto, their respective successors and assigns permitted hereby and, to the
extent expressly contemplated hereby, the Related Parties of each of the
Administrative Agent and the Lenders) any legal or equitable right, remedy or
claim under or by reason of this Agreement.

             (b)   Any
Lender may assign to one or more Eligible Assignees all or a portion of its
rights and obligations under this Agreement (including all or a portion of its
Commitment, the Loans at the time owing to it and its interests in any other
Extension of Credit); provided that (i) except in the case of an
assignment of the entire remaining amount of the assigning Lender’s Commitment
and the Loans and rights to reimbursement under any LC Disbursement at the time
owing to it or in the case of an assignment to a Lender, an Affiliate of a
Lender or an Approved Fund with respect to a Lender, the aggregate amount of the
Commitment (which for this purpose includes Loans outstanding thereunder) of the assigning Lender
subject to each such assignment (determined as of the date the Assignment and
Acceptance with respect to such assignment is delivered to the Administrative
Agent) shall not be less than $1,000,000, in the case of any assignment of a
Loan or rights to reimbursement under an LC Disbursement, unless each of the
Administrative Agent, the Issuing Bank and, so long as no Event of Default has
occurred and is continuing, the Borrowers otherwise consent (each such consent
not to be unreasonably withheld or delayed), (ii) each partial assignment shall
be made as an assignment of a proportionate part of all the assigning Lender’s
rights and obligations under this Agreement with respect to the Loan or rights
to reimbursement under an LC Disbursement or the Commitment assigned, except
that this clause (ii) shall not prohibit any Lender from assigning all or a
portion of its rights and obligations among separate Commitments on a non pro
rata basis, (iii) the parties to each assignment shall execute and deliver to
the Administrative Agent an Assignment and Acceptance, together with a
processing and recordation fee of $3,500, and the Eligible Assignee, if it shall
not be a Lender, shall deliver to the Administrative Agent an Administrative
Questionnaire and (iv) such Lender has notified AESC of such assignment. Subject
to acceptance and recording thereof by the Administrative Agent pursuant to
paragraph (c) of this Section, from and after the effective date specified in
each Assignment and Acceptance, the Eligible Assignee thereunder shall be a
party hereto and, to the extent of the interest assigned by such Assignment and
Acceptance, have the rights and obligations of a Lender under this Agreement,
and the assigning Lender thereunder shall, to the extent of the interest
assigned by such Assignment and Acceptance, be released from its obligations
under this Agreement (and, in the case of an Assignment and Acceptance covering
all of the assigning Lender’s rights and obligations under this Agreement, such
Lender shall cease to be a party hereto but shall continue to be entitled to the
benefits of Sections 2.15, 2.16, 2.17 and 11.3. Any assignment or transfer by a
Lender of rights or obligations under this Agreement that does not comply with
this paragraph shall be treated for purposes of this Agreement as a sale by such
Lender of a participation in such rights and obligations in accordance with
paragraph (d) of this Section.

             (c)   The
Administrative Agent, acting solely for this purpose as an agent of AESC, shall
maintain at one of its offices in New York, New York a copy of each Assignment
and Acceptance delivered to it and a register for the recordation of the names
and addresses of the Lenders, and the Commitments of, and principal amount of
the Loans owing to, each Lender pursuant to the terms hereof from time to time
(the “Register”). The entries in the Register shall 

68

be conclusive,
and the Borrowers, the Administrative Agent and the Lenders may treat each
Person whose name is recorded in the Register pursuant to the terms hereof as a
Lender hereunder for all purposes of this Agreement, notwithstanding notice to
the contrary. The Register shall be available for inspection by AESC and any
Lender, at any reasonable time and from time to time upon reasonable prior
notice.

             (d)   Any
Lender may, without the consent of, or notice to, any Borrower or the
Administrative Agent, sell participations to one or more banks or other entities
(a “Participant”) in all or a portion of such Lender’s rights
and/or obligations under this Agreement (including all or a portion of its
Commitment and/or the Loans or rights to reimbursement under an LC Disbursement
owing to it); provided that (i) such Lender’s obligations under this
Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations
and (iii) each Borrower, the Administrative Agent, the Issuing Bank and the
other Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender’s rights and obligations under this Agreement. Any
agreement or instrument pursuant to which a Lender sells such a participation
shall provide that such Lender shall retain the sole right to enforce this
Agreement and to approve any amendment, modification or waiver of any provision
of this Agreement; provided that such agreement or instrument may provide
that such Lender will not, without the consent of the Participant, agree to any
amendment, modification or waiver with respect to the following to the extent
affecting such Participant: (i) increase the Commitment of any Lender without
the written consent of such Lender, (ii) reduce the principal amount of any Loan
or reduce the rate of interest thereon, or reduce any fees payable hereunder,
without the written consent of each Lender affected thereby, (iii) postpone the
date fixed for any payment of any principal of, or interest on, any Loan or
interest thereon or any fees hereunder or reduce the amount of, waive or excuse
any such payment, or postpone the scheduled date for the termination or
reduction of any Commitment, without the written consent of each Lender affected
thereby, (iv) change Section 2.17(b) or (c) in a manner that would alter the pro
rata sharing of payments required thereby, without the written consent of each
Lender, (v) change any of the provisions of this Section or the definition of
“Required Lenders” or any other provision hereof specifying the number or
percentage of Lenders required to waive, amend or modify any rights hereunder or
make any determination or grant any consent hereunder, without the consent of
each Lender; (vi) release any guarantor or limit the liability of any such
guarantor under any guaranty agreement without the written consent of each
Lender except to the extent such release is expressly provided under the terms
of such guaranty agreement; or (vii) release all or substantially all collateral
(if any) securing any of the Obligations. Subject to paragraph (e) of this
Section, each Borrower agrees that each Participant shall be entitled to the
benefits of Sections 2.15, 2.16, and 2.17 to the same extent as
if it were a Lender and had acquired its interest by assignment pursuant to
paragraph (b) of this Section. To the extent permitted by law, each Participant
also shall be entitled to the benefits of Section 11.7 as though it were a
Lender, provided such Participant agrees to be subject to Section 11.7 as though
it were a Lender.

             (e)   Notwithstanding
anything to the contrary contained herein, any Lender (a “Granting
Lender”) may grant to a special purpose funding vehicle (an
“SPV”), identified as such in writing from time to time by the
Granting Lender to the Administrative Agent and AESC, the option to provide to
the Borrowers all or any part of any Loan that such Granting initial Lender
would otherwise be obligated to make to the Borrowers pursuant to this 

69

Agreement; provided, that (i) nothing herein shall constitute a
commitment by any SPV to make any Loan and (ii) if an SPV elects not to exercise
such option or otherwise fails to provide all or any part of any Loan, the
Granting Lender shall be obligated to make such Loan pursuant to the terms
hereof. The making of a Loan by an SPV hereunder shall utilize the Commitment of
the Granting Lender to the same extent, and as if such Loan were made by such
Granting Lender. Each party hereto hereby agrees that no SPV shall be liable for
any indemnity or similar payment obligation under this Agreement (it being
understood and agreed that the Granting Lender shall remain responsible for all
of its obligations hereunder and shall protect and indemnify each Borrower, the
Administrative Agent and the other Lenders for all liabilities, costs and
expenses resulting from the acts and omissions of the SPV). 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 commercial paper or other
senior indebtedness of any SPV, it will not institute against, or join any other
person in instituting against, such SPV any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceedings under the laws of the United
States or any State. Notwithstanding anything to the contrary in this Section
11.4, any SPV may (i) with notice to, but without the prior written consent of,
AESC and the Administrative Agent and without paying any processing fee
therefor, assign all or a portion of its interests in any Loans to the Granting
Lender or to any financial institutions (consented to by AESC and the
Administrative Agent) providing liquidity and/or credit support to or for the
account of such SPV to support the funding or maintenance of Loans and (ii)
disclose any non-public information relating to the Loans on a confidential
basis in the manner set forth in Section 11.11.

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

             (g)   Any
Lender may at any time pledge or assign a security interest in all or any
portion of its rights under this Agreement to secure obligations of such Lender,
including without limitation any pledge or assignment to secure obligations to a
Federal Reserve Bank; provided that no such pledge or assignment of a
security interest shall release a Lender from any of its obligations hereunder
or substitute any such pledgee or assignee for such Lender as a party
hereto.

SECTION 11.5. Governing Law; Jurisdiction;
  Consent to Service of Process.

             (a)   This
Agreement and the other Loan Documents shall be construed in accordance with and
be governed by the law (without giving effect to the conflict of law principles
thereof) of the State of New York. 

             (b)   Each
Borrower hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of the United States District Court
of the Southern 

70

District of New York, and of the Supreme Court of the State of
New York sitting in New York County and any appellate court from any thereof, in
any action or proceeding arising out of or relating to this Agreement or any
other Loan Document or the transactions contemplated hereby or thereby, or for
recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in such New York state
court or, to the extent permitted by applicable law, such Federal court. Each of
the parties hereto agrees that a final judgment in any such action or proceeding
shall be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law. Nothing in this Agreement or
any other Loan Document shall affect any right that the Administrative Agent or
any Lender may otherwise have to bring any action or proceeding
relating to this Agreement or any other Loan Document against any Borrower or
its properties in the courts of any jurisdiction.

             (c)   Each
Borrower irrevocably and unconditionally waives any objection which it may now
or hereafter have to the laying of venue of any such suit, action or proceeding
described in paragraph (b) of this Section and brought in any court referred to
in paragraph (b) of this Section. Each of the parties hereto irrevocably waives,
to the fullest extent permitted by applicable law, the defense of an
inconvenient forum to the maintenance of such action or proceeding in any such
court.

             (d)   Each
party to this Agreement irrevocably consents to the service of process in the
manner provided for notices in Section 11.1. Nothing in this Agreement or in any
other Loan Document will affect the right of any party hereto to serve process
in any other manner permitted by law.

SECTION 11.6. WAIVER OF JURY TRIAL.
  

             EACH
PARTY HERETO IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE
LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY
OR INDIRECTLY ARISING OUT OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR
ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT
OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT
SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE
FOREGOING WAIVER, AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE
BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG
OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

SECTION 11.7. Right of Setoff.
  

             In
addition to any rights now or hereafter granted under applicable law and not by
way of limitation of any such rights, each Lender shall have the right, at any
time or from time to time upon the occurrence and during the continuance of an
Event of Default, without prior notice to any Borrower, any such notice being
expressly waived by such Borrower to the extent permitted 

71

by applicable law, to
set off and apply against all deposits (general or special, time or demand,
provisional or final) of any Borrower at any time held or other obligations at
any time owing by such Lender to or for the credit or the account of such
Borrower against any and all Obligations held by such Lender irrespective of
whether such Lender shall have made demand hereunder and although such
Obligations may be unmatured. Each Lender agrees to notify promptly the
Administrative Agent and the applicable Borrower after any such setoff and any
application made by such Lender; provided, that the failure to give such
notice shall not affect the validity of such setoff and application. 

SECTION 11.8. Counterparts; Integration.
  

             This
Agreement may be executed by one or more of the parties to this Agreement on any
number of separate counterparts (including by facsimile), and all of said
counterparts taken together shall be deemed to constitute one and the same
instrument. This Agreement, the Fee Letter, the other Loan Documents and the
Administrative Agent Fee Letter constitute the entire agreement among the
parties hereto and thereto regarding the subject matters hereof and thereof and
supersede all prior agreements and understandings, oral or written, regarding
such subject matters.

SECTION 11.9. Survival.

             All
covenants, agreements, representations and warranties made by either Borrower
herein and in the certificates or other instruments delivered in connection with
or pursuant to this Agreement shall be considered to have been relied upon by
the other parties hereto and shall survive the execution and delivery of this
Agreement and the making of any Loans, regardless of any investigation made by
any such other party or on its behalf and notwithstanding that the
Administrative Agent or any Lender may have had notice or knowledge of any
Default or incorrect representation or warranty at the time any credit is
extended hereunder, and shall continue in full force and effect as long as the
principal of or any accrued interest on any Loan or any fee or any other amount
payable under this Agreement is outstanding and unpaid and so long as the
Commitments have not expired or terminated. The provisions of Sections 2.15, 2.16, 2.17, and 11.3 and
Article X shall survive and remain in full force and effect regardless of the
consummation of the transactions contemplated hereby, the repayment of the
Loans, the expiration or termination of the Commitments or the termination of
this Agreement or any provision hereof. All representations and warranties made
herein, in the certificates, reports, notices, and other documents delivered
pursuant to this Agreement shall survive the execution and delivery of this
Agreement and the other Loan Documents, and the making of the Loans.

SECTION 11.10. Severability.
  

             Any
provision of this Agreement or any other Loan Document held to be illegal,
invalid or unenforceable in any jurisdiction, shall, as to such jurisdiction, be
ineffective to the extent of such illegality, invalidity or unenforceability
without affecting the legality, validity or enforceability of the remaining
provisions hereof or thereof; and the illegality, invalidity or unenforceability
of a particular provision in a particular jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

72

SECTION 11.11. Confidentiality.
  

             Each
of the Administrative Agent, the Issuing Bank and each Lender agrees to take
normal and reasonable precautions to maintain the confidentiality of any
information designated in writing as confidential and provided to it by any
Borrower or any Subsidiary of such Borrower, except that unless otherwise agreed
to in writing by such Lender, such information may be disclosed (i) to its
Affiliates, to other Lenders and their respective Affiliates and to any actual
or prospective assignee or Participant (provided that each such Person
shall agree to be bound by the confidentiality provision of this Section 11.11)
and any other Related Party of the Administrative Agent or any such Lender,
including without limitation accountants, legal counsel and other advisors, (ii)
to the extent required by applicable laws or regulations or by any subpoena or
similar legal process, (iii) to the extent requested by any regulatory agency or
authority, (iv) to the extent that such information becomes publicly available
other than as a result of a breach of this Section, or which becomes available
to the Administrative Agent, any Lender or any Related Party of any of the
foregoing on a nonconfidential basis from a source other than any Borrower, (v)
in connection with the exercise of any remedy hereunder or any suit, action or
proceeding relating to this Agreement or the enforcement of rights hereunder, or
(vi) with the consent of any Borrower. Any Person required to maintain the
confidentiality of any information as provided for in this Section shall be
considered to have complied with its obligation to do so if such Person has
exercised the same degree of care to maintain the confidentiality of such
information as such Person would accord its own confidential
information.

SECTION 11.12. Waiver of Effect of Corporate
  Seal. 

             Each
Borrower represents and warrants that it is not required to affix its corporate
seal to this Agreement or any other Loan Document pursuant to any requirement of
law or regulation, and waives any shortening of the statute of limitations that
may result from not affixing the corporate seal to this Agreement or such other
Loan Documents.

SCHEDULE 4.5

ENVIRONMENTAL MATTERS

Clean Air Act Section 114 Letter. The United States
Environmental Protection Agency (“USEPA”) has initiated investigation and
enforcement actions against a number of electric utilities regarding the
interpretation of routine maintenance and major modification of a facility which
could trigger the applicability of New Source Performance Standards under the
Clean Air Act. AESC, and one of its affiliates, has received a Section 114
letter from the USEPA on or about the third quarter of 2000 requiring it to
provide records and information relevant to the operation and maintenance of ten
electric generating facilities. AESC, and one of its affiliates, responded with
the information requested. EPA has not yet responded to these submittals. While
AESC, and one of its affiliates, cannot predict the outcome of this matter any
future enforcement action settlement could result in material capital
expenditures or operating costs which may not be recouped by rate increases. For
further information see “Environmental Issues” in the Allegheny Energy, Inc.
Forms 10-K and 10-K/A filed on April 1, 2002 and
April 9, 2002, respectively.

NOx Compliance. In response to an EPA NOx SIP call
rule, AESC, and one of its affiliates, may be required to make significant
reductions in its NOx emissions before May 2003 in Pennsylvania and Maryland and
May 2004 in West Virginia. These reductions would require significant capital
expenditures. For further information see “Environmental Issues” in the
Allegheny Energy, Inc. Forms 10-K and 10-K/A filed on April 1, 2002
and April 9, 2002, respectively.

Mercury. USEPA has announced plans to regulate
mercury emissions from electric generating facilities in conjunction with, or
shortly after, they complete further studies on the issue. AESC, and one of its
affiliates, could be subject to additional emission control requirements on or
before 2008, which could result in significant capital expenditures and
operating costs.

Facility Operations and Releases. AESC, and one of
its affiliates, owns and operates a number of active generation facilities with
active coal combustion by-product disposal sites and processing operations,
sedimentation ponds, coal piles, storage tanks (above and below ground), and
other ancillary equipment necessary for operations. Some of these units have
been owned or operated for many years and releases from some of these units may
have occurred. AESC, and one of its affiliates, projects the need to site new
disposal facilities within the next ten years which will involve significant
capital expenditures and operating costs.

Open Consent Orders/Decrees. AESC is subject to two
open consent orders: (i) Harrison Power Station Stormwater Consent Order (WVDEP,
January 21, 2000, Order No. 4495), final evaluation November 13, 2003; and (ii)
R. Paul Smith Power Station (MDE, July 20, 1992) particulate testing
for Unit 4, annually, and particulate testing for Unit 3, biannually.

Pleasants Power Station Stack Replacement. In order
to comply with SO2 and particulate matter regulations and to maintain proper
station operations AESC, and one of its affiliates, is conducting an engineering
study for the construction of a new stack. Implementation of study results could
result in significant capital expenditures and operating costs.

Ladies and Gentlemen:

             We
make reference to the Credit Agreement (the “Credit Agreement”)

             The
Borrowers and _______________ (the “Assuming Lender”) each hereby
agree as follows:

             1.   The
  Assuming Lender proposes to become an Assuming Lender pursuant to Section
  2.6(c) of the Credit Agreement and, in that connection, hereby agrees with the
  Administrative Agent and the Borrowers that it shall become a Lender for all
  purposes of the Credit Agreement on the applicable Commitment Increase Date.
  

             2.   The
  Assuming Lender (a) confirms that it has received a copy of the Credit
  Agreement, together with copies of the financial statements referred to in
  Section 4.4 thereof and such other documents and information as it has
  deemed appropriate to make its own credit analysis and decision to enter into
  this Assumption Agreement; (b) agrees that it will, independently and
  without reliance upon the Administrative Agent, the Issuing Bank or any other
  Lender and based on such documents and information as it shall deem
  appropriate at the time, continue to make its own credit decisions in taking
  or not taking action under the Credit Agreement; (c) appoints and
  authorizes the Administrative Agent to take such action as agent on its behalf
  and to exercise such powers and discretion under the Credit Agreement as are
  delegated to the Administrative Agent by the terms thereof, together with such
  powers and discretion as are reasonably incidental thereto; and (d) agrees
  that it will perform in accordance with their terms all of the obligations
  that by the terms of the Credit Agreement are required to be performed by it
  as a Lender.

             3.   Following
  the execution hereof, this Assumption Agreement will be delivered to the
  Administrative Agent for acceptance and recording by the Administrative Agent.
  The effective date for this Assumption Agreement (the “Effective
  Date”) shall be the applicable Commitment Increase Date.

             4.   Upon
  satisfaction of the applicable conditions set forth in Section 2.6(c) of the
  Credit Agreement and upon such acceptance and recording by the Administrative
  Agent, as of the Effective Date, the Assuming Lender shall be a party to the
  Credit Agreement and have all of the rights and obligations of a Lender
  thereunder.
