amounts such that the Total Outstandings of such Bank at any time shall not

an extension of the Termination Date on any Extension Date, it shall give
written notice to that effect to the Agent not less than 45 nor more than 60
days prior to such Extension Date, whereupon the Agent shall notify each of the
Banks of such notice. Each Bank will use its best efforts to respond to such
request, whether affirmatively or negatively, within 30 days. If all Banks
respond affirmatively (any Bank which does not respond being deemed to have
responded negatively), then, subject to receipt by the Agent prior to such
Extension Date of


<PAGE>


counterparts of an Extension Agreement in substantially the form of Exhibit H
duly completed and signed by all of the parties hereto, the Termination Date
shall be extended, effective on such Extension Date, for a period of one year to
the date stated in such Extension Agreement.

         SECTION 2.02. NOTICE OF BORROWING. (a) The relevant Borrower shall give
the Agent notice (a "NOTICE OF BORROWING") not later than 11:00 A.M. (New York
City time) on (x) the date of each Base Rate Borrowing and (y) the third
Euro-Dollar Business Day before each Euro-Dollar Borrowing, specifying:

                  (i) the date of such Borrowing, which shall be a Domestic
         Business Day in the case of a Base Rate Borrowing or a Euro-Dollar
         Business Day in the case of a Euro-Dollar Borrowing,

                  (ii) the aggregate amount of such Borrowing,

                  (iii) whether the Loans comprising such Borrowing are to bear
         interest initially at the Base Rate or a Euro-Dollar Rate, and

         the initial Interest Period applicable thereto, subject to the
         provisions of the definition of Interest Period.

         (b) Upon receipt of a Notice of Borrowing, the Agent shall promptly
notify each Bank of the contents thereof and of such Bank's ratable share of
such Borrowing and such Notice of Borrowing shall not thereafter be revocable by
any Borrower.

         (c) Not later than 2:00 P.M. (New York City time) on the date of each
Borrowing, each Bank shall (except as provided in subsection (d) of this
Section) make available its ratable share of such Borrowing, in Federal or other
funds immediately available in New York City, to the Agent at its address
referred to in Section 10.01. Unless the Agent determines that any applicable
condition specified in Article 3 has not been satisfied, the Agent will make the
funds so received from the Banks available to the Borrower requesting such
Borrowing at the Agent's aforesaid address.

         (d) If any Bank makes a new Loan hereunder to any Borrower on a day on
which such Borrower is to repay all or any part of an outstanding Loan from such
Bank, such Bank shall apply the proceeds of its new Loan to make such repayment
and only an amount equal to the difference (if any) between the amount being
borrowed and the amount being repaid shall be made available by such Bank to the
Agent as provided in


<PAGE>


subsection (c), or remitted by such Borrower to the Agent as provided in Section
2.12, as the case may be.

         (e) Unless the Agent shall have received notice from a Bank prior to
the date of any Borrowing that such Bank will not make available to the Agent
such Bank's share of such Borrowing, the Agent may assume that such Bank has
made such share available to the Agent on the date of such Borrowing in
accordance with subsections (c) and (d) of this Section 2.02 and the Agent may,
in reliance upon such assumption, make available to the Borrower requesting such
Borrowing on such date a corresponding amount. If and to the extent that such
Bank shall not have so made such share available to the Agent, such Bank and
such Borrower severally agree to repay to the Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
such amount is made available to such Borrower until the date such amount is
repaid to the Agent, at (i) in the case of such Borrower, a rate per annum equal
to the higher of the Federal Funds Rate and the interest rate applicable thereto
pursuant to Section 2.06 and (ii) in the case of such Bank, the Federal Funds
Rate. If such Bank shall repay to the Agent such corresponding amount, such
amount so repaid shall constitute such Bank's Loan included in such Borrowing
for purposes of this Agreement.

Subsidiaries, from time to time during the Revolving Credit Period. In addition,
and notwithstanding any reference in any Existing Letter of Credit to the
Existing Credit Facility, on and as of the Effective Date, each Existing Letter
of Credit shall be deemed to be a Letter of Credit and to have been issued on
the Effective Date (by the Fronting Bank that issued or was deemed to have
issued such Existing Letter of Credit under the Existing Credit Facility)
pursuant to this Section 2.03(a); PROVIDED, HOWEVER, that nothing in this
Section 2.03(a) shall extend, modify or otherwise affect the existing expiry

any party hereto, to have purchased from such Fronting Bank, a participation in
such Letter of Credit and the related Letter of Credit Liabilities, in the
amount required so that the participations of the Banks (including such Fronting
Bank's retained participation) therein shall be in proportion to their
respective Commitments.

         (c) REQUIRED TERMS. Each Letter of Credit (other than the Letter of
Credit identified on Schedule III) issued hereunder shall:

         five Letters of Credit may be issued with stated amounts less than
         $300,000 (or the equivalent thereof in an Alternative Currency) and (y)
         not more than the amount that would, after giving effect to the
         issuance thereof (and the related purchase and sale of participations
         therein pursuant to Section 2.03(b)) cause the Total Outstandings of
         any Bank to equal its Commitment; and

                  (iii) be in a form acceptable to the Fronting Bank.

         (d) NOTICE OF ISSUANCE. Except in the case of Existing Letters of
Credit, a Borrower may request that a Letter of Credit be issued by giving the
Agent and the Fronting Bank for such Letter of Credit a notice (a "NOTICE OF
ISSUANCE") at least two Domestic Business Days before such Letter of Credit is

         Borrower shall reimburse such Fronting Bank by paying such amount to
         the Agent not later than 12:00 noon, New York City time, on the day
         that such payment is made, if the Borrower receives notice of such
         payment before 10:00 A.M., New York City time, on such day, or if such

                  other circumstance or happening whatsoever, whether or not
                  similar to any of the foregoing.

         (g) PAYMENTS BY BANKS WITH RESPECT TO LETTERS OF CREDIT.

                  (i) Each Bank shall make available an amount equal to its
         ratable share of any Drawing under a Letter of Credit, in Federal or
         other funds immediately available in New York City, to the applicable
         Fronting Bank by 3:00 P.M. (New York City time) on the date on which
         the relevant Borrower is required to reimburse such Fronting Bank with
         respect to such Drawing pursuant to Section 2.03(f)(i), together with
         interest on such amount for the period from and including the date of
         such Drawing to but excluding the date upon which such amount is to be
         made available at the Federal Funds Rate on the date of such drawing,
         at such Fronting Bank's address referred to in Section 10.01; PROVIDED
         that each Bank's obligation shall be reduced by its pro rata share of
         any reimbursement theretofore paid by the relevant Borrower in respect
         of such Drawing pursuant to Section 2.03(f)(i). The applicable Fronting
         Bank shall notify each Bank of the amount of such Bank's obligation
         (which, in the case of any payment under an Alternative Currency Letter
         of Credit, shall be the Dollar Equivalent thereof) in respect of any
         drawing under a Letter of Credit not later than 1:30 P.M. (New York
         City time) on the day such payment by such Bank is due. Each Bank shall


<PAGE>


         be subrogated to the rights of the applicable Fronting Bank against the
         applicable Borrower to the extent such payment due from such Bank to
         such Fronting Bank is paid, plus interest thereon, from and including
         the day such amount is due from such Bank to such Fronting Bank to but
         excluding the day such Borrower makes payment to such Fronting Bank
         pursuant to Section 2.03(f)(i), whether before or after judgment, at a
         rate per annum equal to the sum of 2% plus the rate applicable to Base
         Rate Loans for such day. In the event that, on the date of any Drawing,
         (x) Total Outstandings exceeds the Maximum Outstanding Exposure (as
         defined in Section 2.16(a) below), (y) the applicable Fronting Bank is
         not reimbursed by the Borrowers on such date for the entire amount of
         such Drawing, and (z) the Banks, pursuant to the last sentence of
         subsection (iv) below, are not obligated to reimburse such Fronting
         Bank for the entire amount of such Drawing, the Agent shall, solely for
         purposes of determining the portion of such Drawing to be reimbursed by
         each Bank, (A) allocate the respective Commitments of the Banks to the
         Letter of Credit Liabilities of each Letter of Credit on such date on a
         pro rata basis (based upon (1) the proportion of the Commitments to the
         aggregate amount of the Letter of Credit Liabilities of all outstanding
         Letters of Credit and (2) each Bank's pro rata share of the
         Commitments), (B) based on such allocation, determine the reimbursement
         obligation of each Bank with respect to such Drawing and (C) promptly
         notify each Bank of the amount of its reimbursement obligation with
         respect to such Drawing.

                  (ii) If any Bank fails to pay any amount required pursuant to
         subsection (i) of this Section 2.03(g) on the date on which such
         payment is due, interest, payable on demand, shall accrue on such
         Bank's obligation to make such payment, for each day from and including
         the date such payment becomes due to but excluding the date such Bank
         makes such payment at a rate per annum equal to the Federal Funds Rate.
         Any payment made by any Bank after 3:00 P.M. (New York City time) on
         any Domestic Business Day shall be deemed for purposes of the preceding
         sentence to have been made on the next succeeding Domestic Business
         Day.

                  (iii) If the relevant Borrower shall reimburse a Fronting Bank
         for any drawing under a Letter of Credit after the Banks shall have
         made funds available to such Fronting Bank with respect to such drawing
         in accordance with subsection (i) of this Section 2.03(g), such
         Fronting Bank shall promptly upon receipt of such reimbursement
         distribute to each Bank its pro rata share thereof, including interest,
         to the extent received by such Fronting Bank.

                  (iv) The several obligations of the Banks to the Fronting
         Banks hereunder


<PAGE>


         shall be absolute, irrevocable and unconditional under any and all
         circumstances whatsoever and shall not be affected by any circumstance,
         including, without limitation, (1) any set-off, counterclaim,
         recoupment, defense or other right which any such Bank or any other
         Person may have against the Agent, any Fronting Bank or any other
         Person for any reason whatsoever; (2) the occurrence or continuance of
         a Default or an Event of Default or the termination of the Commitments
         or any Letter of Credit; (3) any adverse change in the condition
         (financial or otherwise) of any Obligor or any other Person; (4) any
         breach of any Financing Document by any party thereto; (5) the fact
         that any condition precedent to the issuance of, or the making of any
         payment under, any Letter of Credit was not in fact met; (6) any
         violation or asserted violation of law by any Bank or any affiliate
         thereof; or (7) to the extent permitted under applicable law, any other
         circumstance, happening or event whatsoever, whether or not similar to
         any of the foregoing. Each payment by each Bank to a Fronting Bank for
         its own account shall be made without any offset, abatement,
         withholding or reduction whatsoever. If a Fronting Bank is required at
         any time (whether before or after the Termination Date) to return to a
         Borrower or to a trustee, receiver, liquidator, custodian or other
         similar official any portion of the payments made by such Borrower to
         such Fronting Bank in payment of any Reimbursement Obligation or
         interest thereon upon the insolvency of such Borrower, or the
         commencement of any case or proceeding under any bankruptcy, insolvency
         or other similar law with respect to such Borrower, each Bank shall, on
         demand of such Fronting Bank, forthwith return to such Fronting Bank
         any amounts transferred to such Bank by such Fronting Bank in respect
         thereof pursuant to this subsection PLUS such Bank's pro rata share of
         any interest on such payments required to be paid to the Person
         recovering such payments PLUS interest on the amount so demanded from
         the day such demand is made, if such demand is made by 2:00 p.m. (New
         York City time), or from the next following Domestic Business Day, if
         such demand is made after 2:00 p.m., to but not including the day such
         amounts are returned by such Bank to such Fronting Bank at a rate per
         annum for each day equal to (A) the Federal Funds Rate for the day of
         such demand and (B) the Base Rate plus 1% for each day thereafter.
         Notwithstanding the foregoing or any other provision contained herein,
         in no event shall any Bank be obligated to make any payment to a
         Fronting Bank to the extent that such payment would cause such Bank's
         pro rata share of the Total Outstandings hereunder to exceed such
         Bank's Commitment; PROVIDED that the foregoing shall not affect the
         obligation of the Borrowers (which is absolute, unconditional and
         irrevocable) to reimburse each Fronting Bank for the entire amount of
         each payment made by such Fronting Bank under a Letter of Credit,
         including any amount thereof that is not paid by any Bank to such
         Fronting Bank (pursuant to this sentence or otherwise).


<PAGE>


         (h) LETTER OF CREDIT COMMISSION; ISSUANCE FEE.

                  (i) LETTER OF CREDIT COMMISSION. Each Borrower agrees to pay
         to the Agent a letter of credit commission with respect to each Letter
         of Credit issued at its request or for its account, computed for each
         day from and including the date of issuance of such Letter of Credit to
         but excluding the last day a drawing is available under such Letter of
         Credit (the "LETTER OF CREDIT TERMINATION DATE"), at the Letter of
         Credit Commission Rate on the aggregate amount available for drawing
         under such Letter of Credit from time to time (whether or not any
         conditions to drawing can then be met), such fee to be for the account
         of the Banks ratably in proportion to their Total Exposures. Such fee
         shall be payable quarterly in arrears on the last Domestic Business Day
         of each January, April, July and October and upon the Termination Date.

                  (ii) ISSUANCE FEE. Each Borrower shall pay to each Fronting
         Bank for its own account such fees with respect to each Letter of
         Credit issued by such Fronting Bank for the account of such Borrower as
         shall have been agreed between such Borrower and such Fronting Bank.

                  (iii) LIMITED LIABILITY OF THE FRONTING BANK. As between a
         Fronting Bank, on the one hand, and a Borrower, on the other, such
         Borrower assumes all risks of any acts or omissions of the beneficiary
         and any transferee of any Letter of Credit with respect to its use of
         such Letter of Credit. Neither Fronting Bank nor any of their
         respective employees, officers or directors shall be liable or
         responsible for: (a) the use which may be made of any Letter of Credit
         or for any acts or omissions of any beneficiary or transferee in
         connection therewith, (b) the validity, sufficiency or genuineness of
         documents, or of any endorsement(s) thereon, even if such documents
         should in fact prove to be in any or all respects invalid,
         insufficient, fraudulent or forged, (c) payment by the Fronting Bank
         against presentation of documents which do not comply with the terms of
         any Letter of Credit, including failure of any documents to bear any
         reference or adequate reference to such Letter of Credit, or (d) any
         other circumstance whatsoever in making or failing to make payment
         under any Letter of Credit; PROVIDED that such Borrower shall have a
         claim against the applicable Fronting Bank, and such Fronting Bank
         shall be liable to such Borrower, to the extent, but only to the
         extent, of any direct, as opposed to consequential or special, damages
         suffered by


<PAGE>


         such Borrower which are found in a final, unappealable judgment of a
         court of competent jurisdiction to have been caused by (i) such
         Fronting Bank's willful misconduct or gross negligence in determining
         whether documents presented under any Letter of Credit comply with the
         terms thereof or (ii) such Fronting Bank's willful failure to pay, or
         gross negligence resulting in a failure to pay, any drawing after the
         presentation to it by the beneficiary (or any transferee of the Letter
         of Credit) of a draft and other required documentation strictly
         complying with the terms and conditions of the Letter of Credit. In
         furtherance and not in limitation of the foregoing, a Fronting Bank may
         accept documents that appear on their face to be in order, without
         responsibility for further investigation.

                  (iv) FRONTING BANKS AND AFFILIATES. Each Fronting Bank shall
         have the same rights and powers under the Financing Documents as any
         other Bank and may exercise or refrain from exercising the same as
         though they were not Fronting Banks (in each case to the extent such
         Fronting Bank is also a Bank), and the Fronting Banks and their
         respective affiliates may accept deposits from, lend money to, and
         generally engage in any kind of business with AES or any Subsidiary or
         affiliate of AES as if they were not Fronting Banks hereunder.

         SECTION 2.04. NOTES. (a) Each Bank may, by notice to a Borrower and the
Agent, request that its Loans to each Borrower be evidenced by a single Note
payable to the order of such Bank for the account of its Applicable Lending
Office in an amount equal to the aggregate unpaid principal amount of such
Bank's Loans to such Borrower.

         (b) Each Bank may, by notice to a Borrower and the Agent, request that
its Loans to such Borrower of a particular type be evidenced by a separate Note
of such Borrower in an amount equal to the aggregate unpaid principal amount of
such Loans. Each such Note shall be in substantially the form of Exhibit A
hereto with appropriate modifications to reflect the fact that it evidences
solely Loans of the relevant type. Each reference in this Agreement to a "Note"
or the "Notes" of such Bank shall be deemed to refer to and include any or all
of such Notes, as the context may require.

         (c) Upon receipt of a Bank's Note pursuant to Section 3.01(b) and
3.02(a), the Agent shall forward such Note to such Bank. Each Bank shall record
the date, amount, type and maturity of each Loan made by it to each Borrower and
the date and amount of each payment of principal made with respect thereto, and
may, if such Bank so elects in connection with any transfer or enforcement of
its Note of any Borrower, endorse on the schedule forming a part thereof
appropriate notations to evidence the foregoing information with respect to each
such Loan to such Borrower then outstanding; PROVIDED that the failure of any
Bank to make any such recordation or endorsement shall not affect


<PAGE>


the obligations of any Obligor under the Financing Documents. Each Bank is
hereby irrevocably authorized by each Borrower so to endorse its Notes and to
attach to and make a part of any Note a continuation of any such schedule as and
when required.

         SECTION 2.05. MATURITY OF LOANS. Each Loan shall mature, and the
principal amount thereof shall be due and payable (together with interest
accrued thereon), on the Termination Date.

         SECTION 2.06. INTEREST RATES. (a) Each Base Rate Loan shall bear
interest on the outstanding principal amount thereof, for each day from the date
such Loan is made until it becomes due, at a rate per annum equal to the Base
Rate for such day. Such interest shall be payable quarterly in arrears on each
Quarterly Payment Date. Any overdue principal of or interest on any Base Rate
Loan shall bear interest, payable on demand, for each day until paid at a rate
per annum equal to the sum of 2% plus the rate otherwise applicable to Base Rate
Loans for such day.

         (b) Each Euro-Dollar Loan shall bear interest on the outstanding
principal amount thereof, for each day during each Interest Period applicable
thereto, at a rate per annum equal to the sum of the Euro-Dollar Margin for such
day plus the Adjusted London Interbank Offered Rate applicable to such Interest
Period. Such interest shall be payable for each Interest Period on the last day
thereof and, if such Interest Period is longer than three months, at intervals
of three months after the first day thereof.

         "EURO-DOLLAR MARGIN" means a rate per annum determined in accordance
with the annexed Pricing Schedule.

         The "ADJUSTED LONDON INTERBANK OFFERED RATE" applicable to any Interest
Period means a rate per annum equal to the quotient obtained (rounded upward, if
necessary, to the next higher 1/100th of 1%) by dividing (i) the applicable
London Interbank Offered Rate by (ii) 1.00 minus the Euro-Dollar Reserve
Percentage.

         The "LONDON INTERBANK OFFERED RATE" applicable to any Interest Period
means the average (rounded upward, if necessary, to the next higher 1/16th of
1%) of the respective rates per annum at which deposits in dollars are offered
to each of the Reference Banks in the London interbank market at approximately
11:00 A.M. (London time) two Business Days before the first day of such Interest
Period in an amount approximately equal to the principal amount of the
Euro-Dollar Loan of such Reference Bank to which such Interest Period is to
apply and for a period of time comparable to


<PAGE>


such Interest Period.

         "EURO-DOLLAR RESERVE PERCENTAGE" means for any day that percentage
(expressed as a decimal) which is in effect on such day, as prescribed by the
Board of Governors of the Federal Reserve System (or any successor) for
determining the maximum reserve requirement for a member bank of the Federal
Reserve System in New York City with deposits exceeding five billion dollars in
respect of "Eurocurrency liabilities" (or in respect of any other category of
liabilities which includes deposits by reference to which the interest rate on
Euro-Dollar Loans is determined or any category of extensions of credit or other
assets which includes loans by a non-United States office of any Bank to United
States residents). The Adjusted London Interbank Offered Rate shall be adjusted
automatically on and as of the effective date of any change in the Euro-Dollar
Reserve Percentage.

         (c) Any overdue principal of or interest on any Euro-Dollar Loan shall
bear interest, payable on demand, for each day from and including the date
payment thereof was due to but excluding the date of actual payment, at a rate
per annum equal to the higher of (i) the sum of 2% plus the Euro-Dollar Margin
for such day plus the Adjusted London Interbank Offered Rate applicable to such
Loan and (ii) the sum of 2% plus the Euro-Dollar Margin for such day plus the
quotient obtained (rounded upward, if necessary, to the next higher 1/100th of
1%) by dividing (x) the average (rounded upward, if necessary, to the next
higher 1/16th of 1%) of the respective rates per annum at which one day (or, if
such amount due remains unpaid more than three Euro-Dollar Business Days, then
for such other period of time not longer than three months as the Agent may
select) deposits in dollars in an amount approximately equal to such overdue
payment due to each of the Reference Banks are offered to such Reference Bank in
the London interbank market for the applicable period determined as provided
above by (y) 1.00 minus the Euro-Dollar Reserve Percentage (or, if the
circumstances described in clause (a) or (b) of Section 8.01 shall exist, at a
rate per annum equal to the sum of 2% plus the rate applicable to Base Rate
Loans for such day).

         (d) The Agent shall determine each interest rate applicable to the
Loans hereunder. The Agent shall give prompt notice to the applicable Borrower
and the participating Banks of each rate of interest so determined, and its
determination thereof shall be conclusive in the absence of manifest error.

         (e) Each Reference Bank agrees to use its best efforts to furnish
quotations to the Agent as contemplated by this Section. If any Reference Bank
does not furnish a timely quotation, the Agent shall determine the relevant
interest rate on the basis of the quotation


<PAGE>


or quotations furnished by the remaining Reference Bank or Banks or, if none of
such quotations is available on a timely basis, the provisions of Section 8.01
shall apply.

         SECTION 2.07. METHOD OF ELECTING INTEREST RATES. (a) The Loans included
in each Borrowing shall bear interest initially at the type of rate specified by
the applicable Borrower in the applicable Notice of Borrowing. Thereafter, the
applicable Borrower may from time to time elect to change or continue the type
of interest rate borne by each Group of Loans (subject to Section 2.07(d) and
the provisions of Article 8), as follows:

                  (i) if such Loans are Base Rate Loans, the applicable Borrower
         may elect to convert such Loans to Euro-Dollar Loans as of any
         Euro-Dollar Business Day;

                  (ii) if such Loans are Euro-Dollar Loans, the applicable
         Borrower may elect to convert such Loans to Base Rate Loans as of any
         Domestic Business Day or elect to continue such Loans as Euro-Dollar
         Loans for an additional Interest Period, subject to Section 2.13 if any
         such conversion is effective on any day other than the last day of an
         Interest Period applicable to such Loans.

         Each such election shall be made by delivering a notice (a "NOTICE OF
INTEREST RATE ELECTION") to the Agent not later than 11:00 A.M. (New York City
time) on the third Euro-Dollar Business Day before the conversion or
continuation selected in such notice is to be effective (unless the relevant
Loans are to be converted from Euro-Dollar Loans to Base Rate Loans, in which
case such notice shall be delivered to the Agent not later than 11:00 A.M. (New
York City time) on the date such conversion is to be effective). A Notice of
Interest Rate Election may, if it so specifies, apply to only a portion of the
aggregate principal amount of the relevant Group of Loans; PROVIDED that (i)
such portion is allocated ratably among the Loans comprising such Group and (ii)
the portion to which such Notice applies, and the remaining portion to which it
does not apply, are each at least $5,000,000 (unless such portion is comprised
of Base Rate Loans). If no such notice is timely received before the end of an
Interest Period for any Group of Euro-Dollar Loans, the applicable Borrower
shall be deemed to have elected that such Group of Loans be converted to Base
Rate Loans at the end of such Interest Period.

         (b) Each Notice of Interest Rate Election shall specify:

                  (i) the Group of Loans (or portion thereof) to which such
         notice applies;

                  (ii) the date on which the conversion or continuation selected
         in such


<PAGE>


         notice is to be effective, which shall comply with the applicable
         clause of Section 2.07(a) above;

                  (iii) if the Loans comprising such Group are to be converted,
         the new type of Loans and, if the Loans resulting from such conversion
         are to be Euro-Dollar Loans, the duration of the next succeeding
         Interest Period applicable thereto; and

                  (iv) if such Loans are to be continued as Euro-Dollar Loans
         for an additional Interest Period, the duration of such additional
         Interest Period.

         Each Interest Period specified in a Notice of Interest Rate Election
shall comply with the provisions of the definition of Interest Period.

         (c) Promptly after receiving a Notice of Interest Rate Election from a
Borrower pursuant to Section 2.07(a) above, the Agent shall notify each Bank of
the contents thereof and such notice shall not thereafter be revocable by any
Borrower.

         (d) A Borrower shall not be entitled to elect to convert any Loans to,
or continue any Loans for an additional Interest Period as, Euro-Dollar Loans if
(i) the aggregate principal amount of any Group of Euro-Dollar Loans created or
continued as a result of such election would be less than $5,000,000 or (ii) a
Default shall have occurred and be continuing when the Borrower delivers notice
of such election to the Agent.

         (e) If any Loan is converted to a different type of Loan, the
applicable Borrower shall pay, on the date of such conversion, the interest
accrued to such date on the principal amount being converted.

         SECTION 2.08. COMMITMENT FEES. AES shall pay to the Agent, for the
account of the Banks ratably in proportion to their Commitments, a commitment
fee at the Commitment Fee Rate on the daily amount by which the aggregate amount
of the Commitments exceeds the aggregate Total Outstandings. Such commitment fee
shall accrue from and including the Effective Date to but excluding the
Termination Date (or earlier date of termination of the Commitments in their
entirety). Accrued commitment fees under this Section 2.08 shall be payable
quarterly in arrears on each March 31, June 30, September 30 and December 31 and
upon the date of termination of the Commitments in their entirety. For this
purpose, "COMMITMENT FEE RATE" means a rate per annum determined in accordance
with the annexed Pricing Schedule.


<PAGE>


         SECTION 2.09. TERMINATION OR REDUCTION OF COMMITMENTS.

         (a) OPTIONAL. AES may, upon at least three Domestic Business Days'
notice to the Agent, (i) terminate the Commitments in their entirety at any
time, if no Loans or Letters of Credit are outstanding at such time or (ii)
ratably reduce from time to time by an aggregate amount of $5,000,000 or any
larger multiple thereof, the aggregate amount of the Commitments in excess of
the aggregate Total Outstandings.

         (b) MANDATORY. (i) SCHEDULED TERMINATION. The Commitments shall
terminate on the Termination Date, and any Loans and Reimbursement Obligations
then outstanding (together with accrued interest thereon) shall be due and
payable on such date.

         (ii) NET CASH PROCEEDS OF ASSET DISPOSITIONS. In the event that AES or
any of its Subsidiaries shall at any time, or from time to time, receive any Net
Cash Proceeds of any Asset Disposition, the Commitments of the Banks shall,
unless the Required Banks otherwise agree, be ratably reduced by such amounts
and at such times as may be required to avoid any requirement that all or any
portion of such Net Cash Proceeds be applied to repay, prepay, repurchase or
defease any Debt of AES that is subordinated in right of payment to the Debt of
AES under the Financing Documents.

         (c) REDUCTIONS PERMANENT. All reductions of the Commitments pursuant to
this Section 2.09 shall be permanent.

         SECTION 2.10. MANDATORY REPAYMENTS OF THE LOANS AND CASH
COLLATERALIZATION OF LETTERS OF CREDIT. If on any date, after giving effect to
the reductions in the Commitments pursuant to Section 2.09, the aggregate Total
Outstandings exceed the aggregate Commitments, the Borrowers shall be jointly
and severally obligated to apply an amount equal to such excess to prepay the
Loans or cash collateralize Letters of Credit, or both. Amounts to be applied
pursuant to the preceding sentence shall be applied first to repay the principal
amount of the Borrowings then outstanding until all such Borrowings shall have
been repaid in full, and if any excess then remains such excess shall be
deposited with the Agent in the Cash Collateral Account to be held, applied or
released for application as provided in Section 2.15 and Section 2.16. The
particular Borrowings to be repaid shall be as designated by AES (or, failing
such designation, as the Agent may determine). Each repayment shall be applied
to repay ratably the Loans of the several Banks included in such Borrowings.
Each payment of principal shall be made together with interest accrued on the
amount repaid to the date of payment.

         SECTION 2.11. OPTIONAL PREPAYMENT OF THE LOANS. (a) Subject in the case
of any


<PAGE>


Euro-Dollar Borrowing to Section 2.13, the Borrowers may, upon at least one
Domestic Business Day's notice to the Agent, prepay any Group of Base Rate Loans
or upon at least three Euro-Dollar Business Days' notice to the Agent, prepay
any Group of Euro-Dollar Loans, in each case in whole at any time, or from time
to time in part in amounts aggregating $5,000,000 or any larger multiple of
$1,000,000, by paying the principal amount to be prepaid together with accrued
interest thereon to the date of prepayment. Each such optional prepayment shall
be applied to prepay ratably the Loans of the several Banks included in such
Group of Loans.

         (b) Upon receipt of a notice of prepayment pursuant to this Section,
the Agent shall promptly notify each Bank of the contents thereof and of such
Bank's ratable share of such prepayment and such notice shall not thereafter be
revocable by any Borrower.

         SECTION 2.12. GENERAL PROVISIONS AS TO PAYMENTS. (a) The Borrowers
shall make each payment of principal of, and interest on, the Loans and
Reimbursement Obligations and of fees hereunder, not later than 12:00 Noon (New
York City time) on the date when due, in Federal or other funds immediately
available in New York City, without set-off, counterclaim or other deduction, to
the Agent at its address referred to in Section 10.01. The Agent will promptly
distribute to each Bank its ratable share of each such payment received by the
Agent for the account of the Banks. Whenever any payment of principal of, or
interest on, the Base Rate Loans or Reimbursement Obligations or of fees shall
be due on a day which is not a Domestic Business Day, the date for payment
thereof shall be extended to the next succeeding Domestic Business Day. Whenever
any payment of principal of, or interest on, the Euro-Dollar Loans shall be due
on a day which is not a Euro-Dollar Business Day, the date for payment thereof
shall be extended to the next succeeding Euro-Dollar Business Day unless such
Euro-Dollar Business Day falls in another calendar month, in which case the date
for payment thereof shall be the next preceding Euro-Dollar Business Day. If the
date for any payment of principal is extended by operation of law or otherwise,
interest thereon shall be payable for such extended time.

         (b) Unless the Agent shall have received notice from a Borrower prior
to the date on which any payment is due from such Borrower to the Banks
hereunder that such Borrower will not make such payment in full, the Agent may
assume that such Borrower has made such payment in full to the Agent on such
date and the Agent may, in reliance upon such assumption, cause to be
distributed to each Bank on such due date an amount equal to the amount then due
such Bank. If and to the extent that such Borrower shall not have so made such
payment, each Bank shall repay to the Agent forthwith on demand


<PAGE>


such amount distributed to such Bank together with interest thereon, for each
day from the date such amount is distributed to such Bank until the date such
Bank repays such amount to the Agent, at the Federal Funds Rate.

         SECTION 2.13. FUNDING LOSSES. If a Borrower makes any payment of
principal with respect to any Euro-Dollar Loan or any Euro-Dollar Loan is
converted to a Base Rate Loan (pursuant to Article 2, 6 or 8 or otherwise) on
any day other than the last day of an Interest Period applicable thereto, or the
last day of an applicable period fixed pursuant to Section 2.06(c), or if a
Borrower fails to borrow, prepay, convert or continue any Euro-Dollar Loans
after notice has been given to any Bank in accordance with Section 2.02(b),
2.07(c) or 2.11(b), such Borrower shall reimburse each Bank within 15 days after
demand for any resulting loss or expense incurred by it (or by an existing or
prospective Participant in the related Loan), including (without limitation) any
loss incurred in obtaining, liquidating or employing deposits from third
parties, but excluding loss of margin for the period after such payment or
conversion or failure to borrow, prepay, convert or continue; PROVIDED that such
Bank shall have delivered to such Borrower a certificate as to the amount of
such loss or expense, which certificate shall be conclusive in the absence of
manifest error.

         SECTION 2.14. COMPUTATION OF INTEREST AND FEES. Interest based on the
Base Rate hereunder shall be computed on the basis of a year of 365 days (or 366
days in a leap year) and paid for the actual number of days elapsed (including
the first day but excluding the last day). All other interest and fees shall be
computed on the basis of a year of 360 days and paid for the actual number of
days elapsed (including the first day but excluding the last day).

         SECTION 2.15. CASH COLLATERAL ACCOUNT. (a) All amounts required to be
deposited as cash collateral with the Agent pursuant to Section 2.10, 2.16 or
Section 6.03 shall be deposited in a cash collateral account (the "CASH
COLLATERAL ACCOUNT") established by the Borrowers with the Agent, to be held,
applied or released for application as provided in this Section 2.15 and Section
2.16.

         (b) If and when any portion of the Letter of Credit Liabilities on
which any deposit of cash collateral was based (the "RELEVANT CONTINGENT
EXPOSURE") shall become fixed (a "DIRECT EXPOSURE") as a result of the payment
by a Fronting Bank of a draft presented under any relevant Letter of Credit
(including any such payment under an Alternative Currency Letter of Credit for
which the relevant Fronting Bank, as a result of fluctuations in currency
exchange rates, is not reimbursed in full by the Banks), the amount of such
Direct Exposure (but not more than the amount in the Cash Collateral


<PAGE>


Account at the time) shall be withdrawn by the Agent from the Cash Collateral
Account and shall be paid to the relevant Fronting Bank to be applied against
such Direct Exposure and the Relevant Contingent Exposure shall thereupon be
reduced by such amount.

         (c) Interest and other payments and distributions made on or with
respect to the cash collateral held by the Agent shall be for the account of the
Borrowers and shall constitute cash collateral to be held by the Agent or
returned to the Borrowers in accordance with subsection (b) of this Section
2.15; PROVIDED that the Agent shall have no obligation to invest any cash
collateral on behalf of the Borrowers or any other Person. Beyond the exercise
of reasonable care in the custody thereof, the Agent shall have no duty as to
any cash collateral in its possession or control or in the possession or control
of any agent or bailee or any income thereon or as to the preservation of rights
against prior parties or any other rights pertaining thereto. The Agent shall be
deemed to have exercised reasonable care in the custody and preservation of the
cash collateral in its possession if the cash collateral is accorded treatment
substantially equal to that which it accords its own property, and shall not be
liable or responsible for any loss or damage to any of the cash collateral, or
for any diminution in the value thereof, by reason of the act or omission of any
agent or bailee selected by the Agent in good faith. All expenses and
liabilities incurred by the Agent in connection with taking, holding and
disposing of any cash collateral (including customary custody and similar fees
with respect to any cash collateral held directly by the Agent) shall be paid by
AES from time to time upon demand. Upon a Default, the Agent shall be entitled
to apply (and, at the request of the Required Banks but subject to applicable
law, shall apply) cash collateral or the proceeds thereof to payment of any such
expenses, liabilities and fees.

         SECTION 2.16. COMPUTATIONS OF OUTSTANDINGS; DETERMINATION OF AVAILABLE
AMOUNT OF ALTERNATIVE CURRENCY LETTERS OF CREDIT. (a) Whenever reference is made
in this Agreement to the Total Outstandings on any date under this Agreement,
such reference shall refer to Total Outstandings on such date after giving
effect to all Extensions of Credit to be made on such date. For purposes of
calculating the Total Outstandings on any date of determination, the aggregate
Available Amount in respect of all Alternative Currency Letters of Credit shall
be deemed to equal the amount thereof most recently reported to the Agent
pursuant to subsection (b) below. At no time shall the Total Outstandings under
this Agreement exceed the sum of (i) the aggregate amount of the Commitments,
PLUS (ii) the Cash Collateral Account (such sum being referred to herein as the
"MAXIMUM OUTSTANDING EXPOSURE"). References to the unused portion of the
Commitments shall refer to the excess, if any, of the Commitments over the Total
Outstandings; and references to the unused portion of any Bank's Commitment
shall refer


<PAGE>


to such Bank's pro rata share of the unused Commitments.

         (b) Each Fronting Bank that issues an Alternative Currency Letter of
Credit shall (i) on the first Domestic Business Day of each calendar month,
deliver to the Agent a schedule listing (A) each outstanding Alternative
Currency Letter of Credit issued by such Fronting Bank, (B) the maximum
aggregate amount available to be drawn under each such Alternative Currency
Letter of Credit at any time on or after such date (denominated in the
applicable Alternative Currency, assuming the compliance with and satisfaction
of all conditions for Drawing enumerated therein) and (C) the equivalent in
Dollars of such amount (as determined by such Fronting Bank on the basis of
exchange rates available to or otherwise used by such Fronting Bank), together
with the applicable exchange rate utilized by such Fronting Bank and the source
thereof (it being agreed and understood that such applicable exchange rate may
be adjusted by a reasonable and customary volatility factor as agreed by AES and
such Fronting Bank), (ii) on the date of issuance of any Alternative Currency
Letter of Credit (including, if any Alternative Currency Letters of Credit are
issued or deemed issued on the Closing Date, on the Closing Date), deliver to
the Agent a schedule listing the information described in clauses (B) and (C)
above, (iii) on the date of any increase or decrease in the Available Amount of
any Alternative Currency Letter of Credit (other than any increase or decrease
attributable solely to currency exchange rate fluctuations), deliver to the
Agent a schedule listing the information described in clauses (B) and (C) above
after giving effect to such increase or decrease (as the case may be), and (iv)
not later than one Domestic Business Day after its receipt of a written request
therefor from the Agent or any Bank, deliver to the Agent a schedule listing the
information described in clauses (A), (B) and (C) above. The Agent shall
promptly after its receipt thereof deliver a copy of each such schedule to the
Borrowers and the Banks. For all purposes under this Agreement, unless otherwise
expressly set forth herein, the Available Amount in respect of each Alternative
Currency Letter of Credit shall be deemed to equal, on any date of
determination, the Dollar Equivalent thereof as most recently reported to the
Agent by the relevant Fronting Bank pursuant to this subsection (b).

         (c) If, on (i) the date that any schedule is delivered by a Fronting
Bank to the Agent pursuant to subsection (b) above, (ii) any date, after giving
effect to reduction in the Commitments, or (iii) any other date, Total
Outstandings on such date (calculated pursuant to subsection (a) and (b) above)
exceeds the Maximum Outstanding Exposure, then within two Domestic Business Days
thereafter the Borrower shall be obligated to deposit cash collateral with the
Agent in the Cash Collateral Account in an amount equal


<PAGE>


to such excess to be held, applied or released for application as provided in
Section 2.15.

         (d) If at any time the Maximum Outstanding Exposure exceeds the Total
Outstandings hereunder, the Borrower may provide a written notice to the Agent
requesting the Agent to withdraw such excess amount from the Cash Collateral
Account and pay such amount to the Borrower, and, provided that no Default shall
have occurred and be continuing, the Agent shall promptly undertake such actions
in accordance with the instructions of the Borrower. If a Default shall have
occurred and be continuing, the Agent shall not take any of the foregoing
actions and, if and when requested by the Required Banks, the amounts held in
the Cash Collateral Account shall be withdrawn by the Agent, and the proceeds
thereof shall be applied by the Agent FIRST to repay the Total Outstandings and
other due and unpaid amounts required to be paid by the Borrower hereunder and
SECOND, so long as no Loans or Letters of Credit are then outstanding, any
remaining amounts shall be paid to the Borrower.

         SECTION 2.17. ALTERNATIVE CURRENCY LETTER OF CREDIT ISSUANCES. It is
understood that, if Letters of Credit are issued in an Alternative Currency, a
circumstance may arise where the United States dollars ("dollars") needed to
reimburse a Fronting Bank may exceed the unused Commitments of the Banks and the
amounts on deposit in the Cash Collateral Account available for that purpose.
This situation could occur if an Alternative Currency exchange rate between the
currency of a Letter of Credit issuance and dollars changes between the date of
issuance of, and the date of funding a Drawing on, an Alternative Currency
Letter of Credit (or funding a deposit to the Cash Collateral Account to cover
issuances in excess of Commitments) so that more dollars are needed to purchase
the Alternative Currency on the date of funding of the Drawing on an Alternative
Currency Letter of Credit (or funding a deposit to the Cash Collateral Account)
than would have been needed to fund a Drawing made on the issuance date of such
Letter of Credit (I.E., the currency of issuance has appreciated against the
dollar between the date of issuance and the date of funding or cash collateral
deposit). In such a circumstance, the Fronting Banks agree as follows: (i) Any
shortfall of Commitments to purchase participations in Letter of Credit Drawings
shall be allocated PRO RATA among the Fronting Banks who have issued Alternative
Currency Letters of Credit for which the currency of issuance has appreciated
against the dollar ("ADVERSE ALTERNATIVE CURRENCY LETTERS OF CREDIT"). The
PRO RATA allocation shall be based on the Dollar Equivalent of the face amount
of each Adverse Alternative Currency Letter of Credit, measured at the issuance
date of each such Adverse Alternative Currency Letter of Credit. Commitments
shall not be used to purchase participations in Adverse Alternative Currency
Letters of Credit to the extent that use of those Commitments covers any
increase in the Dollar Equivalent of an Adverse Alternative Letter of Credit
since the date of issuance of the Letter of Credit if following such purchase
remaining unused Commitments are


<PAGE>


insufficient to purchase participations in the remaining outstanding Letters of
Credit. (ii) Amounts deposited in the Cash Collateral Account shall be allocated
FIRST to cover shortfalls to the extent existing on the last date of actual
deposit to the Cash Collateral Account, or if later, the most recent date of
determination pursuant to Section 2.16(b), and SECOND to any additional
shortfalls (allocated PRO RATA among such shortfalls); PROVIDED, funds on
deposit in the Cash Collateral Account, if any, may not be applied to fund a
Drawing on an Adverse Alternative Currency Letter of Credit to the extent those
funds have been allocated to cover an exposure existing on the last date of
deposit to the Cash Collateral Account if following the application a previously
covered exposure is left without cash collateral.

<PAGE>


                         REPRESENTATIONS AND WARRANTIES

         AES represents and warrants that:

         SECTION 4.01. CORPORATE EXISTENCE AND POWER. Each Obligor is a
corporation (or limited liability company, as applicable) duly incorporated (or
formed, as applicable), validly existing and in good standing under the laws of
the State of Delaware (or, in the case of any AES Finance Subsidiary, its
jurisdiction of incorporation), and has all corporate or other organizational
powers and all material governmental licenses, authorizations, consents and
approvals required to carry on its business as now conducted.

         SECTION 4.02. CORPORATE AND GOVERNMENTAL AUTHORIZATION; NO
CONTRAVENTION. The execution, delivery and performance by each Obligor of the
Financing Documents to which it is a party are within such Obligor's corporate
or other organizational powers, have been duly authorized by all necessary
corporate or other organizational action, require no action by or in respect of,
or filing with, any governmental body, agency or official and do not contravene,
or constitute a default under, any provision of applicable law or regulation or
of the certificate of incorporation (or certificate of formation, as applicable)
or by-laws (or other organizational documents, as applicable) of such Obligor or
of any agreement, judgment, injunction, order, decree or other instrument
binding upon AES or any of its Subsidiaries or result in the creation or
imposition of any Lien on any asset of AES or of any Material AES Entity.

         SECTION 4.03. COMPLIANCE WITH LAWS. AES and each of its Subsidiaries
are in compliance, in all material respects, with all applicable laws,
ordinances, rules, regulations, and requirements of governmental authorities
(including, without limitation, Environmental Laws and ERISA and the rules and
regulations thereunder).

         SECTION 4.04. BINDING EFFECT. This Agreement constitutes a valid and
binding agreement of each Borrower and each other Financing Document, when
executed and delivered in accordance with this Agreement, will constitute a
valid and binding obligation of each Obligor that is a party thereto, in each
case enforceable in accordance with its terms.

         SECTION 4.05. FINANCIAL INFORMATION.


<PAGE>


         (a) The consolidated balance sheet of AES and its Consolidated
Subsidiaries as of December 31, 1999 and the related consolidated statements of
operations and cash flows for the fiscal year then ended, reported on by
Deloitte & Touche and set forth in the AES 1999 Form 10-K, a copy of which has
been delivered to each of the Banks, fairly present, in conformity with
generally accepted accounting principles, the consolidated financial position of
AES and its Consolidated Subsidiaries as of such date and their consolidated
results of operations and cash flows for such fiscal year.

         (b) Since December 31, 1999 there has been no material adverse change
in the business, financial position, results of operations or prospects of AES
and its Consolidated Subsidiaries, considered as a whole.

         SECTION 4.06. LITIGATION. Except as disclosed in the AES 1999 Form
10-K, there is no action, suit or proceeding pending against, or to the
knowledge of AES threatened against or affecting, AES or any of its Subsidiaries
before any court or arbitrator or any governmental body, agency or official in
which there is a reasonable possibility of an adverse decision which could
materially adversely affect the business, consolidated financial position or
consolidated results of operations of AES and its Consolidated Subsidiaries or
which in any manner draws into question the validity of any Financing Document.

         SECTION 4.07. COMPLIANCE WITH ERISA. Each member of the ERISA Group has
fulfilled its obligations under the minimum funding standards of ERISA and the
Internal Revenue Code with respect to each Plan and is in compliance in all
material respects with the currently applicable provisions of ERISA and the
Internal Revenue Code with respect to each Plan. No member of the ERISA Group
has (i) sought a waiver of the minimum funding standard under Section 412 of the
Internal Revenue Code in respect of any Plan, (ii) failed to make any
contribution or payment to any Plan or Multiemployer Plan or in respect of any
Benefit Arrangement, or made any amendment to any Plan or Benefit Arrangement,
which has resulted or could result in the imposition of a Lien or the posting of
a bond or other security under ERISA or the Internal Revenue Code or (iii)
incurred any liability in excess of $100,000 under Title IV of ERISA other than
a liability to the PBGC for premiums under Section 4007 of ERISA.

         SECTION 4.08. ENVIRONMENTAL MATTERS.

         (a) In the ordinary course of its business, each of AES and its
Subsidiaries conducts an ongoing review of the effect of Environmental Laws on
the business, operations and properties of AES or such Subsidiary, in the course
of which it identifies and evaluates associated liabilities and costs
(including, without limitation, any capital or


<PAGE>


operating expenditures required for clean-up or closure of properties presently
or previously owned, any capital or operating expenditures required for
investigation, to achieve or maintain compliance with environmental protection
standards imposed by Environmental Laws or as a condition of any license, permit
or contract, any related constraints on operating activities, including any
periodic or permanent shutdown of any facility or reduction in the level of or
change in the nature of operations conducted thereat, any costs or liabilities
in connection with off-site disposal of wastes or Hazardous Substances by AES or
its Subsidiaries, and any actual or potential liabilities to third parties,
including employees, and any related costs and expenses). On the basis of this
review, AES has reasonably concluded that such associated liabilities and costs,
including the costs of compliance with Environmental Laws, are unlikely to have
a material adverse effect on the business, financial condition, results of
operations or prospects of AES and its Consolidated Subsidiaries, considered as
a whole.

         (b) There are no facts, circumstances or conditions that are reasonably
likely to result in liabilities arising under Environmental Laws that could have
a material adverse effect on the business, financial conditions, results of
operations or prospects of AES and its Consolidated Subsidiaries, considered as
a whole.

         SECTION 4.09. TAXES. United States Federal income tax returns of AES
and its Subsidiaries have been examined and closed through the fiscal year ended
December 31, 1986. AES and its Subsidiaries have filed all United States Federal
income tax returns and AES and all Material AES Entities have filed all other
material tax returns which are required to be filed by them and have paid all
taxes due as indicated on such returns or pursuant to any assessment received by
AES or any Subsidiary or any Material AES Entity other than any such taxes that
are being diligently contested in good faith through appropriate proceedings and
for which adequate reserves have been established in accordance with generally
accepted accounting principals. The charges, accruals and reserves on the books
of AES, its Subsidiaries and all Material AES Entities in respect of taxes or
other governmental charges are, in the opinion of AES, adequate.

         SECTION 4.10. MATERIAL AES ENTITIES. Each Material AES Entity is a
corporation (or limited liability company, as applicable) duly incorporated (or
formed, as applicable), validly existing and (other than any Material AES Entity
that is not incorporated under the laws of the United States or any political
subdivision thereof) in good standing under the laws of its jurisdiction of
incorporation (or jurisdiction of formation, as applicable). Each Material AES
Entity has all corporate or other organizational powers and all


<PAGE>


material governmental licenses, authorization, consents and approvals required
to carry on its business as proposed to be conducted and has all governmental
licenses, authorizations, consents and approvals required to have been obtained
prior to the date hereof and which are material to the operation of its business
as proposed to be conducted, except to the extent that the failure to obtain any
such license, authorization, consent or approval, individually or in the
aggregate, could not reasonably be expected to have a material adverse effect
upon the business, financial condition, operations, property and prospects of
AES and its Consolidated Subsidiaries, taken as a whole.

         SECTION 4.11. NOT AN INVESTMENT COMPANY. None of the Obligors is an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended.

         SECTION 4.12. PUBLIC UTILITY HOLDING COMPANY ACT. Neither AES nor any
of its Subsidiaries is subject to regulation as a "holding company" or a

any transaction in connection with any joint enterprise or other joint
arrangement with, any Affiliate; PROVIDED, HOWEVER, that the foregoing

any lawful dividend so long as, after giving effect thereto, no Default shall
have occurred and be continuing, (b) AES or any Subsidiary of AES from making
sales to or purchases from any Affiliate and, in connection therewith, extending
credit or making payments, or from making payments for services rendered by any

apply in a similar transaction with a Person not an Affiliate, (c) AES or any
Subsidiary of AES from making payments of principal, interest and premium on any
Debt of AES or such Subsidiary held by an Affiliate if the terms of such Debt
are substantially as favorable to AES or such Subsidiary as the terms which

which was not an Affiliate and (d) AES or any Subsidiary of AES from
participating in, or effecting any transaction in connection with, any joint
enterprise or other joint arrangement with any Affiliate if AES or such
Subsidiary participates in the ordinary course of its business and on a basis no
less advantageous than the basis on which such Affiliate participates. The
provisions of this Section 5.17 shall not apply to (i) transactions between AES
or any of its Subsidiaries, on the one hand, and any employee of AES or any of
its Subsidiaries, on the other hand, that are approved by the Board of Directors

interests in Power Projects and unrelated businesses, so long as:

                  (I) each such Intermediate Holding Company's direct and
         indirect interest in any Power Project or unrelated business shall be
         limited to the ownership of Capital Stock or Debt obligations of a
         Person with a direct or indirect interest in such Power Project or
         unrelated business;

                  (II) no Lien shall exist upon any asset of any Intermediate

         (B) AES Electric may make Investments in Power Projects owned by NIGEN

                                    ARTICLE 7

                                    THE AGENT

         SECTION 7.01. APPOINTMENT AND AUTHORIZATION. Each Bank irrevocably
appoints and authorizes the Agent to take such action as agent on its behalf and
to exercise such powers under the Financing Documents as are delegated to the
Agent by the terms thereof, together with all such powers as are reasonably
incidental thereto.

         SECTION 7.02. AGENT AND AFFILIATES. Citibank, N.A. shall have the same
rights and powers under the Financing Documents as any other Bank and may
exercise or refrain from exercising the same as though it were not the Agent,
and Citibank, N.A. and its affiliates may accept deposits from, lend money to,
and generally engage in any kind of business with AES or any Subsidiary or
affiliate of AES as if it were not the Agent under the Financing Documents.

         SECTION 7.03. ACTION BY AGENT. The obligations of the Agent under the
Financing Documents are only those expressly set forth therein. Without limiting
the generality of the foregoing, the Agent shall not be required to take any
action with respect to any Default, except as expressly provided in Article 6.

         SECTION 7.04. CONSULTATION WITH EXPERTS. The Agent may consult with
legal counsel (who may be counsel for any Borrower), independent public
accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken by it in good faith in accordance with the
advice of such counsel, accountants or experts.

         SECTION 7.05. LIABILITY OF AGENT. Neither the Agent nor any of its
affiliates nor any of their respective directors, officers, agents or employees
shall be liable for any action taken or not taken by it in connection herewith
(i) with the consent or at the request of the Required Banks or (ii) in the
absence of its own gross negligence or willful misconduct. Neither the Agent nor
any of its affiliates nor any of their respective directors, officers, agents or
employees shall be responsible for or have any duty to ascertain, inquire into
or verify (i) any statement, warranty or representation made in connection with
the Financing Documents or any Extension of Credit hereunder; (ii) the
performance or observance of any of the covenants or agreements of any Obligor;
(iii) the satisfaction of


<PAGE>


any condition specified in Article 3, except receipt of items required to be
delivered to the Agent; or (iv) the validity, effectiveness or genuineness of
the Financing Documents or any other instrument or writing furnished in
connection therewith. The Agent shall not incur any liability by acting in
reliance upon any notice, consent, certificate, statement or other writing
(which may be a bank wire, telex, facsimile transmission or similar writing)
believed by it to be genuine or to be signed by the proper party or parties.

         SECTION 7.06. INDEMNIFICATION. Each Bank shall, ratably in accordance
with its Commitment, indemnify the Agent, and each Fronting Bank, each of their
respective affiliates and the respective directors, officers, agents and
employees of any of them (to the extent not reimbursed by the Obligors) against
any cost, expense (including counsel fees and disbursements), claim, demand,
action, loss or liability (except such as result from such indemnitees' gross
negligence or willful misconduct) that such indemnitees may suffer or incur in
connection with the Financing Documents or any action taken or omitted by such
indemnitees thereunder.

         SECTION 7.07. CREDIT DECISION. Each Bank acknowledges that it has,
independently and without reliance upon the Agent, any Fronting Bank or any
other Bank, 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 Bank also acknowledges that it will, independently and without
reliance upon the Agent, any Fronting Bank or any other Bank, 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 any action under this
Agreement.

         SECTION 7.08. SUCCESSOR AGENT. The Agent may resign at any time by
giving notice thereof to the Banks and the Borrowers. Upon any such resignation,
the Required Banks shall have the right to appoint a successor Agent. If no
successor Agent shall have been so appointed by the Required Banks, and shall
have accepted such appointment, within 30 days after the retiring Agent gives
notice of resignation, then the retiring Agent may, on behalf of the Banks,
appoint a successor Agent, which shall be a commercial bank organized or
licensed under the laws of the United States of America or of any State thereof
and having a combined capital and surplus of at least $ 100,000,000. Upon the
acceptance of its appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the rights
and duties of the retiring Agent, and the retiring Agent shall be discharged
from its duties and obligations hereunder. After any retiring Agent's
resignation hereunder as Agent, the provisions of


<PAGE>


this Article shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was Agent.

         SECTION 7.09. AGENT'S FEE. AES shall pay to the Agent for its own
account fees in the amounts and at the times previously agreed upon between AES
and the Agent.

                                    ARTICLE 8

                             CHANGE IN CIRCUMSTANCES

         SECTION 8.01. BASIS FOR DETERMINING INTEREST RATE INADEQUATE OR UNFAIR.
If on or prior to the first day of any Interest Period for any Euro-Dollar
Borrowing:

         (a) the Agent is advised by the Reference Banks that deposits in
dollars (in the applicable amounts) are not being offered to the Reference Banks
in the relevant market for such Interest Period, or

         (b) Banks having 50% or more of the aggregate amount of the Commitments
advise the Agent that the Adjusted London Interbank Offered Rate as determined
by the Agent will not adequately and fairly reflect the cost to such Banks of
funding their Euro-Dollar Loans for such Interest Period,

         the Agent shall forthwith give notice thereof to the Borrowers and the
Banks, whereupon until the Agent notifies the Borrowers that the circumstances
giving rise to such suspension no longer exist, (i) the obligations of the Banks
to make Euro-Dollar Loans, or to continue or convert outstanding Loans as or
into Euro-Dollar Loans, shall be suspended and (ii) each outstanding Euro-Dollar
Loan shall be converted into a Base Rate Loan on the last day of the then
current Interest Period applicable thereto. Unless a Borrower notifies the Agent
at least two Domestic Business Days before the date of any Euro-Dollar Borrowing
for which a Notice of Borrowing has previously been given that it elects not to
borrow on such date such Borrowing shall instead be made as a Base Rate
Borrowing.

         SECTION 8.02. ILLEGALITY. If, on or after the date of this Agreement,
the adoption of any applicable law, rule or regulation, or any change in any
applicable law, rule or regulation, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by any Bank (or its Euro-Dollar Lending Office) with any request or directive
(whether or not having the force of law) of


<PAGE>


any such authority, central bank or comparable agency shall make it unlawful or
impossible for any Bank (or its Euro-Dollar Lending Office) to make, maintain or
fund its Euro-Dollar Loans to any Borrower and such Bank shall so notify the
Agent, the Agent shall forthwith give notice thereof to the other Banks and AES,
whereupon until such Bank notifies AES and the Agent that the circumstances
giving rise to such suspension no longer exist, the obligation of such Bank to
make Euro-Dollar Loans to such Borrower, or to convert outstanding Loans into
Euro-Dollar Loans or continue outstanding Loans as Euro-Dollar Loans, shall be
suspended. Before giving any notice to the Agent pursuant to this Section, such
Bank shall designate a different Euro-Dollar Lending Office if such designation
will avoid the need for giving such notice and will not, in the judgment of such
Bank, be otherwise disadvantageous to such Bank. If such notice is given, each
Euro-Dollar Loan of such Bank then outstanding shall be converted to a Base Rate
Loan either (i) on the last day of the then current Interest Period applicable
to such Euro-Dollar Loan if such Bank may lawfully continue to maintain and fund
such Loan as a Euro-Dollar Loan to such day or (ii) immediately if such Bank
shall determine that it may not lawfully continue to maintain and fund such Loan
as a Euro-Dollar Loan to such day. Interest and principal on any such Base Rate
Loan shall be payable on the same dates as, and on a pro rata basis with, the
interest and principal payable on the related Euro-Dollar Loans of the other
Banks.

         SECTION 8.03. INCREASED COST AND REDUCED RETURN. (a) If on or after the
date hereof, the adoption of any applicable law, rule or regulation, or any
change in any applicable law, rule or regulation, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by any Bank (or its Applicable Lending Office) or any
Fronting Bank (any Bank (or its Applicable Lending Office) and any Fronting Bank
being referred to in this Section 8.03 as a "CREDIT PARTY") with any request or
directive (whether or not having the force of law) of any such authority,
central bank or comparable agency shall impose, modify or deem applicable any
reserve (including, without limitation, any such requirement imposed by the
Board of Governors of the Federal Reserve System, but excluding with respect to
any Euro-Dollar Loan any such requirement included in an applicable Euro-Dollar
Reserve Percentage), special deposit, insurance assessment or similar
requirement against assets of, deposits with or for the account of, or credit
extended by, any Credit Party or shall impose on any Credit Party or on the
London interbank market any other condition affecting its Euro-Dollar Loans, its
Note or Notes, the Letters of Credit or its participation therein or its
obligation to make Euro-Dollar Loans or to issue Letters of Credit or to
participate therein and the


<PAGE>


result of any of the foregoing is to increase the cost to such Credit Party of
making or maintaining any Euro-Dollar Loan or issuing any Letter of Credit or
participating therein, or to reduce the amount of any sum received or receivable
by such Credit Party under this Agreement or under its Note or Notes with
respect thereto, by an amount deemed by such Credit Party to be material, then,
within 15 days after demand by such Credit Party (with a copy to the Agent), AES
shall pay to such Credit Party such additional amount or amounts as will
compensate such Credit Party for such increased cost or reduction.

         (b) If any Credit Party shall have determined that, after the date
hereof, the adoption of any applicable law, rule or regulation regarding capital
adequacy, or any change in any such law, rule or regulation, or any change in
the interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or any request or directive regarding capital adequacy
(whether or not having the force of law) of any such authority, central bank or
comparable agency, has or would have the effect of reducing the rate of return
on capital of such Credit Party (or its Parent) as a consequence of such Credit
Party's obligations hereunder to a level below that which such Credit Party (or
its Parent) could have achieved but for such adoption, change, request or
directive (taking into consideration its policies with respect to capital
adequacy) by an amount deemed by such Credit Party to be material, then from
time to time, within 15 days after demand by such Credit Party (with a copy to
the Agent), AES shall pay to such Credit Party such additional amount or amounts
as will compensate such Credit Party (or its Parent) for such reduction.

         (c) Each Credit Party will promptly notify AES and the Agent of any
event of which it has knowledge, occurring after the date hereof, which will
entitle such Credit Party to compensation pursuant to this Section and will
designate a different Applicable Lending Office if such designation will avoid
the need for, or reduce the amount of, such compensation and will not, in the
judgment of such Credit Party, be otherwise disadvantageous to such Credit
Party. A certificate of any Credit Party claiming compensation under this
Section and setting forth the additional amount or amounts to be paid to it
hereunder shall be conclusive in the absence of manifest error. In determining
such amount, such Credit Party may use any reasonable averaging and attribution
methods.

         SECTION 8.04. TAXES. (a) Any and all payments by any Borrower to or for
the account of any Bank, any Fronting Bank or the Agent hereunder or under any
other Financing Document shall be made free and clear of and without deduction
for any and all present or future taxes, duties, levies, imposts, deductions,
charges or withholdings, and all liabilities with respect thereto, excluding, in
the case of each Bank, each Fronting


<PAGE>


Bank and the Agent, taxes imposed on its income (including branch profit taxes),
franchise and similar taxes and other taxes imposed on it that, in any such
case, would not have been imposed but for a material connection between such
Bank, such Fronting Bank or the Agent (as the case may be) and the jurisdiction
imposing such taxes (other than a material connection arising by reason of this
Agreement or any other Financing Document or the receipt of payments made
hereunder or thereunder) (all such non-excluded taxes, duties, levies, imposts,
deductions, charges, withholdings and liabilities being hereinafter referred to
as "TAXES"). If any Borrower shall be required by law to deduct any Taxes from
or in respect of any sum payable hereunder or under any other Financing Document
to any Bank, any Fronting Bank or the Agent, (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 8.04) such
Bank, such Fronting Bank or the Agent (as the case may be) receives an amount
equal to the sum it would have received had no such deductions been made, (ii)
such Borrower shall make such deductions, (iii) such Borrower shall pay the full
amount deducted to the relevant taxation authority or other authority in
accordance with applicable law and (iv) such Borrower shall furnish to the
Agent, at its address referred to in Section 10.01, the original or a certified
copy of a receipt evidencing payment thereof.

         (b) In addition, each Borrower agrees to pay any present or future
stamp or documentary taxes and any other excise or property taxes, or charges or
similar levies which arise from any payment made by it hereunder or under any
Note or from the execution or delivery of, or otherwise with respect to, this
Agreement or any other Financing Document (hereinafter referred to as "OTHER
TAXES").

         (c) Each Borrower agrees to indemnify each Bank, each Fronting Bank and
the Agent for the full amount of Taxes or Other Taxes (including, without
limitation, any Taxes or Other Taxes imposed or asserted by any jurisdiction on
amounts payable under this Section 8.04) paid by such Bank, such Fronting Bank
or the Agent (as the case may be) and any liability (including penalties,
interest and expenses) arising therefrom or with respect thereto. This
indemnification shall be made within 15 days from the date such Bank, such
Fronting Bank or the Agent (as the case may be) makes demand therefor.

         (d) Each Bank organized under the laws of a jurisdiction outside the
United States, on or prior to the date of its execution and delivery of this
Agreement in the case of each Bank listed on the signature pages hereof and on
or prior to the date on which it becomes a Bank in the case of each other Bank,
and from time to time thereafter if requested in writing by AES (but only so
long as such Bank remains lawfully able to do so), shall provide AES with two
duly completed and accurate copies of Internal Revenue


<PAGE>


Service form 1001 or 4224, as appropriate, or any successor form prescribed by
the Internal Revenue Service, certifying that such 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 certifying that the
income receivable pursuant to this Agreement is effectively connected with the
conduct of a trade or business in the United States. If the form provided by a
Bank at the time such Bank first becomes a party to this Agreement indicates a
United States interest withholding tax rate in excess of zero, withholding tax
at such rate shall be considered excluded from "Taxes" as defined in Section
8.04(a).

         (e) For any period with respect to which a Bank has failed to provide
AES with the appropriate form pursuant to Section 8.04(d) (unless such failure
is due to a change in treaty, law or regulation occurring subsequent to the date
on which a form originally was required to be provided), such Bank shall not be
entitled to indemnification under Section 8.04(a) with respect to Taxes imposed
by the United States; PROVIDED, HOWEVER, that should a Bank, which is otherwise
exempt from or subject to a reduced rate of withholding tax, become subject to
Taxes because of its failure to deliver a form required hereunder, the Borrowers
shall take such steps as such Bank shall reasonably request to assist such Bank
to recover such Taxes.

         (f) If any Borrower is required to pay additional amounts to or for the
account of any Bank pursuant to this Section 8.04, then such Bank will change
the jurisdiction of its Applicable Lending Office so as to eliminate or reduce
any such additional payment which may thereafter accrue if such change, in the
judgment of such Bank, is not otherwise disadvantageous to such Bank.

         (g) Each Bank, each Fronting Bank and the Agent agrees that it will
promptly (within 30 days) after receiving notice thereof from any taxing
authority, notify AES of the assertion of any liability by such taxing authority
with respect to Taxes or Other Taxes; PROVIDED, that the failure to give such
notice shall not relieve AES of its obligations under this Section 8.04 except
to the extent that AES has been prejudiced by such failure and except that AES
shall not be liable for penalties, interest or expenses accruing after such 30
day period until such time as it receives the notice contemplated above, after
which time it shall be liable for interest, penalties and expenses accruing
after such receipt.

         (h) If any Bank, a Fronting Bank or the Agent shall receive a credit or
refund from


<PAGE>


a taxing authority (as a result of any error in the imposition of Tax or Other
Tax by such taxing authority) with respect to and actually resulting from an
amount of such Taxes or Other Taxes paid by a Borrower pursuant to subsection
(a) or (c) above, such Bank, such Fronting Bank or the Agent shall promptly pay
to AES the amount so received (without interest thereon, whether or not
received).

         SECTION 8.05. BASE RATE LOANS SUBSTITUTED FOR AFFECTED EURO-DOLLAR
LOANS. If (i) the obligation of any Bank to make, or to continue or to convert
outstanding Loans as or to, Euro-Dollar Loans to any Borrower has been suspended
pursuant to Section 8.02 or (ii) any Bank has demanded compensation under
Section 8.03 or 8.04 with respect to its Euro-Dollar Loans to any Borrower and
such Borrower shall, by at least five Euro-Dollar Business Days' prior notice to
such Bank through the Agent, have elected that the provisions of this Section
shall apply to such Bank, then, unless and until such Bank notifies AES that the
circumstances giving rise to such suspension or demand for compensation no
longer exist, all Loans to such Borrower which would otherwise be made by such
Bank as (or continued or converted to) Euro-Dollar Loans shall be made instead
as Base Rate Loans (on which interest and principal shall be payable
contemporaneously with the related Euro-Dollar Loans of the other Banks). If
such Bank notifies such Borrower that the circumstances giving rise to such
suspension or demand for compensation no longer exist, the principal amount of
each such Base Rate Loan shall be converted into a Euro-Dollar Loan on the first
day of the next succeeding Interest Period applicable to the related Euro-Dollar
Loans of the other Banks.

                                    ARTICLE 9

                                    GUARANTY

         SECTION 9.01. THE GUARANTY. Subject, in the case of any AES Finance
Subsidiary, to the provisions of Section 9.07, each Guarantor hereby
unconditionally guarantees the full and punctual payment (whether at stated
maturity, upon acceleration or otherwise) of the principal of and interest on
each Note issued by the applicable Borrower pursuant to this Agreement, and the
full and punctual payment of all other amounts payable by such Borrower under
this Agreement. Upon failure by a Borrower to pay punctually any such amount,
the applicable Guarantor shall, subject, in the case of any AES Finance
Subsidiary, to the provisions of Section 9.07, forthwith on demand pay the
amount not so paid at the place and in the manner specified in this Agreement.
Without limiting the generality of the foregoing, each Guarantor's liability
hereunder shall extend to all amounts which constitute part of the obligations
guaranteed by it hereunder and would be owed by a Borrower hereunder but for the
fact that they are unenforceable or not


<PAGE>

allowable due to the existence of a bankruptcy, reorganization or similar
proceeding involving such Borrower.

         SECTION 9.02. GUARANTY UNCONDITIONAL. The obligations of each Guarantor
hereunder shall be unconditional and absolute and, without limiting the
generality of the foregoing, shall not be released, discharged or otherwise
affected by:

                  (i) any extension, renewal, settlement, compromise, waiver or
         release in respect of any obligation of any other Obligor under any
         Financing Document, by operation of law or otherwise;

                  (ii) any modification or amendment of or supplement to any
         Financing Document;

                  (iii) any release, impairment, non-perfection or invalidity of
         any direct or indirect security for any obligation of any other Obligor
         under any Financing Document;

                  (iv) any change in the corporate existence, structure or
         ownership of any Obligor, or any insolvency, bankruptcy, reorganization
         or other similar proceeding affecting any other Obligor or its assets
         or any resulting release or discharge of any obligation of any other
         Obligor contained in any Financing Document;

                  (v) the existence of any claim, set-off or other rights which
         such Guarantor may have at any time against any other Obligor, the
         Agent, any Fronting Bank, any Bank or any other Person, whether in
         connection herewith or with any unrelated transactions; PROVIDED that
         nothing herein shall prevent the assertion of any such claim by
         separate suit or compulsory counterclaim;

                  (vi) any invalidity or unenforceability relating to or against
         any other Obligor for any reason of any Financing Document, or any
         provision of applicable law or regulation purporting to prohibit the
         payment by any other Obligor of the principal of or interest on any
         Note or any other amount payable by it under any Financing Document; or

                  (vii) any other act or omission to act or delay of any kind by
         any Obligor,


<PAGE>


         the Agent, any Fronting Bank, any Bank or any other Person or any other
         circumstance whatsoever which might, but for the provisions of this
         paragraph, constitute a legal or equitable discharge of or defense to a
         Guarantor's obligations hereunder.

         SECTION 9.03. DISCHARGE ONLY UPON PAYMENT IN FULL, REINSTATEMENT IN
CERTAIN CIRCUMSTANCES. Each Guarantor's obligations hereunder shall remain in
full force and effect until the Commitments shall have terminated, the principal
of and interest on the Notes and all other amounts payable by any Obligor under
any Financing Document shall have been paid in full and all Letters of Credit
shall have expired or been terminated. If at any time any payment of principal
of or interest on any Note or any other amount payable by any Borrower under any
Financing Document is rescinded or must be otherwise restored or returned upon
the insolvency, bankruptcy or reorganization of such Borrower or otherwise, the
applicable Guarantor's obligations hereunder with respect to such payment shall
be reinstated at such time as though such payment had been due but not made at
such time.

         SECTION 9.04. WAIVER BY THE GUARANTORS. Each Guarantor irrevocably
waives acceptance hereof, presentment, demand, protest and any notice not
provided for herein, as well as any requirement that at any time any action be
taken by any Person against the applicable Borrower or any other Person.

         SECTION 9.05. SUBROGATION. Upon making any payment with respect to a
Borrower under this Article 9, the applicable Guarantor shall be subrogated to
the rights of the payee against such Borrower with respect to such payment;
PROVIDED that neither Guarantor shall enforce any payment by way of subrogation
until all amounts of principal of and interest on the Notes and all other
amounts payable by any Borrower under any Financing Document shall have been
paid in full.

         SECTION 9.06. STAY OF ACCELERATION. In the event that acceleration of
the time for payment of any amount payable by a Borrower under any Financing
Document is stayed upon insolvency, bankruptcy or reorganization of such
Borrower, all such amounts otherwise subject to acceleration under the terms of
this Agreement shall nonetheless be payable by the applicable Guarantor
hereunder forthwith on demand by the Agent made at the request of the requisite
proportion of the Banks specified in Article 6 of this Agreement.

         SECTION 9.07. LIMITATION OF LIABILITY. The obligations of any AES
Finance Subsidiary under this Article 9 shall be limited to an aggregate amount
equal to the


<PAGE>


         largest amount that would not render its obligations under this Article
         9 subject to avoidance under Section 548 of the Bankruptcy Code or any
         comparable provisions of any applicable state law.

                                   ARTICLE 10

                                  MISCELLANEOUS

         SECTION 10.01. NOTICES. All notices, requests and other communications
to any party hereunder shall be in writing (including bank wire, telex,
facsimile transmission or similar writing) and shall be given to such party: (w)
in the case of AES, any Fronting Bank or the Agent, at its address or telex or
facsimile transmission number set forth on the signature pages hereof, (x) in
the case of any AES Finance Subsidiary, in care of AES at the address or telex
or facsimile transmission number of AES set forth on the signature pages hereof,
(y) in the case of any Bank, at its address or telex or facsimile transmission
number set forth in its Administrative Questionnaire or (z) in the case of any
party, at such other address or telex or facsimile transmission number as such
party may hereafter specify for the purpose by notice to the Agent, the Fronting
Banks and AES. Each such notice, request or other communication shall be
effective (i) if given by telex, when such telex is transmitted to the telex
number specified in or pursuant to this Section and the appropriate answerback
is received, (ii) if given by mail, 72 hours after such communication is
deposited in the mails with first class postage prepaid, addressed as aforesaid
or (iii) if given by any other means, when delivered at the address specified in
or pursuant to this Section; PROVIDED that notices to the Agent or a Fronting
Bank under Article 2 or Article 8 shall not be effective until received.

         SECTION 10.02. NO WAIVERS. No failure or delay by the Agent, any
Fronting Bank or any Bank in exercising any right, power or privilege hereunder
or under any other Financing Document shall operate as a waiver thereof nor
shall any single or partial exercise thereof preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. The
rights and remedies herein provided shall be cumulative and not exclusive of any
rights or remedies provided by law.

         SECTION 10.03. EXPENSES; INDEMNIFICATION. (a) AES shall pay (i) all
out-of-pocket expenses of the Agent, including reasonable fees and disbursements
of special counsel for the Agent, in connection with the preparation and
administration of this Agreement and the other Financing Documents, any waiver
or consent hereunder or any amendment hereof or any Default or alleged Default
hereunder and (ii) if an Event of Default occurs, all out-of-pocket expenses
incurred by the Agent, each Fronting Bank and each Bank,


<PAGE>


including (without duplication) the fees and disbursements of outside counsel
and the allocated cost of inside counsel, in connection with such Event of
Default and collection, bankruptcy, insolvency and other enforcement proceedings
resulting therefrom.

         (b) AES agrees to indemnify the Agent, each Fronting Bank and each
Bank, their respective affiliates and the respective directors, officers, agents
and employees of the foregoing (each an "INDEMNITEE") and hold each Indemnitee
harmless from and against any and all liabilities, losses, damages, costs and
expenses of any kind, including, without limitation, the reasonable fees and
disbursements of counsel, which may be incurred by such Indemnitee in connection
with any investigative, administrative or judicial proceeding (whether or not
such Indemnitee shall be designated a party thereto) brought or threatened
relating to or arising out of the Financing Documents or any actual or proposed
use of proceeds of Loans or Letters of Credit hereunder or the issuance or
deemed issuance of any Letter of Credit hereunder; PROVIDED that no Indemnitee
shall have the right to be indemnified hereunder for such Indemnitee's own gross
negligence or willful misconduct as determined by a court of competent
jurisdiction.

         SECTION 10.04. SHARING OF SET-OFFS. Each Bank agrees that if it shall,
by exercising any right of set-off or counterclaim or otherwise, receive payment
of a proportion of the aggregate amount due with respect to the Total
Outstandings of such Bank which is greater than the proportion received by any
other Bank in respect of the aggregate amount due with respect to the Total
Outstandings of such other Bank, the Bank receiving such proportionately greater
payment shall purchase such Participations in the Total Outstandings of the
other Banks, and such other adjustments shall be made, as may be required so
that all such payments with respect to the Total Outstandings of the Banks shall
be shared by the Banks pro rata; PROVIDED that nothing in this Section shall
impair the right of any Bank to exercise any right of set-off or counterclaim it
may have and to apply the amount subject to such exercise to the payment of
indebtedness of a Borrower other than its indebtedness in respect of the Total
Outstandings of any Bank. Each Borrower agrees, to the fullest extent it may
effectively do so under applicable law, that any holder of a participation in a
Note or in any Letter of Credit Liability, whether or not acquired pursuant to
the foregoing arrangements, may exercise rights of set-off or counterclaim and
other rights with respect to such participation as fully as if such holder of a
participation were a direct creditor of such Borrower in the amount of such
participation.

         SECTION 10.05. AMENDMENTS AND WAIVERS. Any provision of this Agreement
or any


<PAGE>


other Financing Document may be amended or waived if, but only if, such
amendment or waiver is in writing and is signed by each Borrower, each Fronting
Bank and the Required Banks (and, if the rights or duties of the Agent are
affected thereby, by the Agent); PROVIDED that no such amendment or waiver
shall, unless signed by all the Banks, (i) increase or decrease the Commitment
of any Bank (except for a ratable decrease in Commitments of all Banks) or
subject any Bank to any additional obligation, (ii) reduce the principal of or
rate of interest on any Loan or Reimbursement Obligation or any fees hereunder,
(iii) postpone the date fixed for any payment of principal of or interest on any
Loan or Reimbursement Obligation or any fees hereunder or for any reduction or
termination of any Commitment, (iv) change the percentage of the Commitments or
of the Total Exposures, or the number of Banks, which shall be required for the
Banks or any of them to take any action under this Section or any other
provision of this Agreement or any other Financing Document, or (v) release
either Subsidiary Guarantor from its obligations under Section 2 of the
Subsidiary Guaranty or any Guarantor from its obligations under Article 9
hereof.

         SECTION 10.06. 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, except that no Borrower may assign
or otherwise transfer any of its rights under this Agreement without the prior
written consent of all Banks.

         (b) Any Bank other than a Conduit Lender may at any time grant to one
or more banks or other institutions (each a "PARTICIPANT") participating
interests in its Commitment or any or all of its Loans or participating
interests in Letter of Credit Liabilities. In the event of any such grant by a
Bank of a participating interest to a Participant, whether or not upon notice to
the Borrowers, the Fronting Banks and the Agent, such Bank shall remain
responsible for the performance of its obligations hereunder, and the Borrowers,
the Fronting Bank and the Agent shall continue to deal solely and directly with
such Bank in connection with such Bank's rights and obligations under this
Agreement. Any agreement pursuant to which any Bank may grant such a
participating interest shall provide that such Bank shall retain the sole right
and responsibility to enforce the obligations of the Borrowers hereunder
including, without limitation, the right to approve any amendment, modification
or waiver of any provision of this Agreement or any other Financing Document;
PROVIDED that such participation agreement may provide that such Bank will not
agree to any modification, amendment or waiver of this Agreement described in
clause (i), (ii), (iii) or (v) of Section 10.05 without the consent of the
Participant. The Borrowers agree that each Participant shall, to the extent
provided in its participation agreement, be entitled to the benefits of Article
8 with respect to its participating interest. An assignment or other transfer
which is not permitted


<PAGE>


by subsection (c) or (d) below shall be given effect for purposes of this
Agreement only to the extent of a participating interest granted in accordance
with this subsection (b).

         (c) Any Bank other than a Conduit Lender may at any time assign to one
or more banks or other institutions (each an "ASSIGNEE") all, or a proportionate
part (equivalent to an initial Commitment of not less than $5,000,000) of all,
of its rights and obligations under this Agreement and the other Financing
Documents, and such Assignee shall assume such rights and obligations, pursuant
to an Assignment and Assumption Agreement in substantially the form of Exhibit G
hereto executed by such Assignee and such transferor Bank, with (and subject to)
the subscribed consent of AES (which shall not be unreasonably withheld but
which shall not be required if an Event of Default shall have occurred and is
continuing),the Fronting Banks and the Agent; PROVIDED that if an Assignee is an
affiliate of such transferor Bank, no such consent shall be required. Upon
execution and delivery of such instrument and payment by such Assignee to such
transferor Bank of an amount equal to the purchase price agreed between such
transferor Bank and such Assignee, such Assignee shall be a Bank party to this
Agreement and shall have all the rights and obligations of a Bank with a
Commitment as set forth in such instrument of assumption, and the transferor
Bank shall be released from its obligations hereunder to a corresponding extent,
and no further consent or action by any party shall be required. Upon the
consummation of any assignment pursuant to this subsection (c), the transferor
Bank, the Agent and the Borrowers shall make appropriate arrangements so that,
if required, new Notes are issued to the Assignee. In connection with any such
assignment, the transferor Bank or Assignee shall pay to the Agent an
administrative fee for processing such assignment in the amount of $3,000. If
the Assignee is not incorporated under the laws of the United States of America
or a state thereof, it shall deliver to AES and the Agent certification as to
exemption from deduction or withholding of any United States federal income
taxes in accordance with Section 8.04. Notwithstanding the foregoing, any
Conduit Lender may assign at any time to its designating Bank hereunder without
the consent of the Borrower or the Agent any or all of the Loans it may have
funded hereunder and pursuant to its designation agreement and without regard to
the limitations set forth in the first sentence of this Section 10.06(c).

         (d) Any Bank may at any time assign all or any portion of its rights
under this Agreement and the other Financing Documents to a Federal Reserve
Bank. No such assignment shall release the transferor Bank from its obligations
hereunder.

         (e) No Assignee, Participant or other transferee of any Bank's rights
shall be


<PAGE>


entitled to receive any greater payment under Section 8.03 or 8.04 than such
Bank would have been entitled to receive with respect to the rights transferred,
unless such transfer is made with AES's prior written consent or by reason of
the provisions of Section 8.02, 8.03 or 8.04 requiring such Bank to designate a
different Applicable Lending Office under certain circumstances or at a time
when the circumstances giving rise to such greater payment did not exist.

         (f) Each of the Borrower, the Agent and each Lender hereby confirms
that it will not institute against a Conduit Lender or join any other Person in
instituting against a Conduit Lender any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceeding under any state bankruptcy or
similar law, for one year and one day after the payment in full of the latest
maturing commercial paper note issued by such Conduit Lender; PROVIDED, however,
that each Bank designating any Conduit Lender hereby agrees to indemnify, save
and hold harmless each other party hereto for any loss, cost, damage or expense
arising out of its inability to institute such a proceeding against such Conduit
Lender during such period of forbearance.

         SECTION 10.07. COLLATERAL. Each of the Banks represents to the Agent
and each of the other Banks that it in good faith is not relying upon any
"margin stock" (as defined in Regulation U or Regulation G) as collateral in the
extension or maintenance of the credit provided for in this Agreement.

         SECTION 10.08. GOVERNING LAW; SUBMISSION TO JURISDICTION. This
Agreement and the other Financing Documents shall be governed by and construed
in accordance with the laws of the State of New York. Each Borrower hereby
submits to the nonexclusive jurisdiction of the United States District Court for
the Southern District of New York and of any New York State court sitting in New
York City for purposes of all legal proceedings arising out of or relating to
this Agreement and the other Financing Documents or the transactions
contemplated hereby. Each Borrower irrevocably waives, to the fullest extent
permitted by law, any objection which it may now or hereafter have to the laying
of the venue of any such proceeding brought in such a court and any claim that
any such proceeding brought in such a court has been brought in an inconvenient
forum.

         SECTION 10.09. COUNTERPARTS; INTEGRATION; EFFECTIVENESS. This Agreement
may be signed in any number of counterparts, each of which shall be an original,
with the same effect as if the signatures thereto and hereto were upon the same
instrument. This Agreement and the other Financing Documents constitute the
entire agreement and understanding among the parties hereto and supersede any
and all prior agreements and understandings, oral or written, relating to the
subject matter hereof. This Agreement


<PAGE>


shall become effective upon receipt by the Agent of counterparts hereof signed
by each of the parties hereto, other than any AES Finance Subsidiary (or, in the
case of any such party as to which an executed counterpart shall not have been
received, receipt by the Agent in form satisfactory to it of telegraphic, telex,
facsimile transmission or other written confirmation from such party of
execution of a counterpart hereof by such party).

         SECTION 10.10. CONFIDENTIALITY. The Agent and each Bank agrees to keep
confidential all non-public information provided to it by AES pursuant to this
Agreement that is designated by AES as confidential; PROVIDED that nothing
herein shall prevent the Agent or any Bank from disclosing any such information
(a) to the Agent, any other Bank or any affiliate of any Bank, (b) to any (i)
actual or prospective transferee, or (ii) Derivatives Obligations counterparty
(or such contractual counterparty's professional advisor), in each case that
agrees to comply with the provisions of this Section, (c) to its employees,
directors, agents, attorneys, accountants and other professional advisors or
those of any of its affiliates, (d) upon the request or demand of any
governmental authority, (e) in response to any order of any court or other
governmental authority or as may otherwise be required pursuant to any
requirement of law, (f) if required to do so in connection with any litigation
or similar proceeding, (g) that has been publicly disclosed, (h) to the National
Association of Insurance Commissioners or any similar organization or any
nationally recognized rating agency that requires access to information about a
Bank's investment portfolio in connection with ratings issued with respect to
such Bank, or (i) in connection with the exercise of any remedy hereunder or
under any other Financing Documents.

         SECTION 10.11. WAIVER OF JURY TRIAL. EACH OF THE BORROWERS, THE
FRONTING BANKS, THE AGENT AND THE BANKS HEREBY IRREVOCABLY WAIVES ANY AND ALL
RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO
THIS AGREEMENT OR THE OTHER FINANCING DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED
HEREBY OR THEREBY.

         SECTION 10.12. SEVERABILITY; MODIFICATION TO CONFORM TO LAW. It is the
intention of the parties that this Agreement be enforceable to the fullest
extent permissible under applicable law, but that the unenforceability (or
modification to conform to such law) of any provision or provisions hereof shall
not render unenforceable, or impair, the remainder hereof. If any provision of
this Agreement shall be held invalid or unenforceable in whole or in part in any
jurisdiction, this Agreement shall, as to such jurisdiction, be deemed amended
to modify or delete, as necessary, the offending provision or provisions and to
alter the bounds thereof in order to render it or them valid and enforceable to
the maximum extent permitted by applicable law, without in any


<PAGE>


manner affecting the validity or enforceability of such provision or provisions
in any other jurisdiction or the remaining provisions hereof in any
jurisdiction.

         SECTION 10.13. APPOINTMENT OF AGENT FOR SERVICE OF PROCESS. Each AES
Finance Subsidiary hereby irrevocably designates, appoints, authorizes and
empowers as its agent for service of process CT Corporation System, at its
offices currently located at 111 Eighth Avenue, 13th Floor, New York, New York
10011, to accept and acknowledge for and on behalf of such AES Finance
Subsidiary service of any and all process, notices or other documents that may
be served in any suit, action or proceeding relating to any Financing Document
in any New York State or Federal court sitting in The State of New York.

         SECTION 10.14. JUDGMENT CURRENCY. If for the purposes of enforcing the
obligations of any Borrower hereunder it is necessary to convert a sum due from
such Person in U.S. dollars ("DOLLARS") into another currency, the parties
hereto agree, to the fullest extent that they may effectively do so, that the
rate of exchange used shall be that at which in accordance with normal banking
procedures the Agent, the Fronting Banks and the Banks could purchase dollars
with such currency at or about 11:00 A.M. (New York City time) on the Domestic
Business Day preceding that on which final judgment is given. The obligations in
respect of any sum due to the Agent, the Fronting Banks and the Banks hereunder
shall, notwithstanding any adjudication expressed in a currency other than
dollars, be discharged only to the extent that on the Domestic Business Day
following receipt by the Agent, the Fronting Banks and the Banks of any sum
adjudged to be so due in such other currency the Agent, the Fronting Banks and
the Banks may in accordance with normal banking procedures purchase dollars with
such other currency; if the amount of dollars so purchased is less than the sum
originally due to the Agent, the Fronting Banks and the Banks in dollars, each
Borrower agrees, to the fullest extent that it may effectively do so, as a
separate obligation and notwithstanding any such adjudication, to indemnify the
Agent, the Fronting Banks and the Banks against such loss, and if the amount of
dollars so purchased exceeds the sum originally due to the Agent, the Fronting
Banks and the Banks, it shall remit such excess to the applicable Borrower.

<PAGE>


Status, Level II Status and Level III Status exists.

         "Level V Status" exists at any date if, at such date, no other Status
exists.

         "Moody's" means Moody's Investors Service, Inc.

         "S&P" means Standard & Poor's Ratings Services.

         "Status" refers to the determination which of Level I Status, Level II
Status, Level III Status, Level IV Status or Level V Status exists at any date.

         The credit ratings to be utilized for purposes of this Schedule are
those assigned to the senior unsecured long-term debt securities of AES
(including, if no senior unsecured long-term debt securities of AES are
outstanding, any such ratings that Moody's or S&P has explicitly stated may be
implied from the ratings it has assigned to AES's outstanding subordinated
unsecured long-term debt securities or, if Moody's or S&P has not explicitly
stated any such implied rating, the rating that is two (including, for this
purpose, "pluses" and "minuses" and "1", "2" and "3" as separate ratings)
ratings above the rating assigned to the subordinated long-term debt securities
of AES by Moody's or S&P, as the case may be) without third-party credit
enhancement, and any rating assigned to any other debt security of AES shall be
disregarded. The rating in effect at any date is that in effect at the close of
business on such date.

         Notwithstanding the foregoing, the Base Rate Margin and the Euro-Dollar
Margin for any date shall be 2.00% over the otherwise applicable rate if an
Event of Default has occurred and is continuing on such date.
