         "Trustee" has the meaning specified in the preamble of this Agreement.

         "UCC" means the Uniform Commercial Code as is in effect from time to
time in the State of New York and any other jurisdiction the laws of which
control the creation or perfection of security interests under the Security
Documents.

                                   ARTICLE II

                    SECURITY INTERESTS AND EXERCISE OF RIGHTS

         SECTION 2.1 Sharing; Priority of Security Interests.


         (a) Each Senior Party agrees that, (i) as among the Senior Parties, the
Security Interest of each Senior Party in any Collateral ranks and will rank
equally in priority with the Security Interest of the other Senior Parties in
the same Collateral and (ii) in respect of matters voted on by the Senior
Parties collectively, the Trustee shall vote all Bonds according to the votes of
a majority of Bondholders voting.

         (b) The priorities specified herein are applicable irrespective of any
statement in any Security Document or in any other agreement to the contrary,
the time or order or method of attachment or perfection of Liens, the time or
order of filing of financing statements or the giving or failure to give notice
of the acquisition or expected acquisition of purchase money or other security
interests.

         (c) The Company hereby covenants and agrees to cause each person
holding Senior Debt to become a party to this Agreement by executing a
Designation Letter and becoming a Senior Party hereunder.

         SECTION 2.2 Subordinated Debt.

         Notwithstanding any provision in any Transaction Document to the
contrary, the Senior Parties hereby agree that (i) the Subordinated Debt
Providers shall be entitled to share in the Collateral or any other payment,
security or guarantee from the Company or any of its Affiliates only to the
extent provided in, and only in accordance with, Articles III and IV and the
Terms of Subordination and (ii) the Subordinated Debt Providers shall not be
entitled to vote or take any actions pursuant to this Agreement or any other
Security Document, or take any other actions with respect to the Collateral
until such time as all of the Secured Obligations owing to all of the Senior
Parties have been satisfied in full. Each Subordinated Debt Provider agrees to
be bound by the Terms of Subordination and agrees that such Terms of
Subordination shall be explicitly incorporated into the Subordinated Loan
Agreement to which it is a party. Each party becoming a Subordinated Debt
Provider pursuant to a Designation Letter shall agree, in such Designation
Letter, to be bound by such Terms of Subordination.



                                       8


         SECTION 2.3 Exercise of Rights Under Security Documents.

         So long as any Secured Obligations remain outstanding, the following
provisions shall apply:

         (a) Subject to Section 5.2(e), if a Trigger Event shall have occurred
and be continuing, and only in such event, upon the written direction of the
Required Senior Parties contained in Senior Party Certificates, the Collateral
Agent, on behalf of the Trustee, the DSR LOC Provider, the CP LOC Provider and
any other Senior Party that is a party to this Agreement, as applicable, shall
be permitted and is hereby authorized to take any and all actions and to
exercise any and all rights, remedies and options which it may have under the
Security Documents or this Agreement; provided, however, that if the underlying
event which caused the Trigger Event is a Bankruptcy Event in respect of the
Company of which the Collateral Agent shall have received written notice, no
written request of the Required Senior Parties shall be required in order for
the Collateral Agent following such Trigger Event to take any and all actions
and to exercise any and all rights and remedies specified in the Security
Documents or this Agreement to be taken in such circumstances. Nothing contained
herein shall be construed as restricting the right of any Senior Party to cause
the acceleration, in accordance with the applicable Senior Document, of the
Senior Debt held by such Party, or in the case of the DSR LOC Provider and the
CP LOC Provider, to terminate the DSR Letter of Credit or CP Letter of Credit
(after giving any required notice to the beneficiary thereof), as the case may
be, or to terminate the ability of the Company to continue any DSR Loans (as
defined in the DSR LOC Reimbursement Agreement) as, or to convert DSR Loans to
Eurodollar Loans (as defined in the DSR LOC Reimbursement Agreement), or in the
case of the DSR LOC Provider, to terminate the ability of the Company to cause
the reinstatement of the DSR Letter of Credit.

         (b) The Senior Parties hereby agree to give each other and the
Collateral Agent written notice of the occurrence of an Event of Default and of
a Trigger Event as soon as practicable after the occurrence thereof; provided,
however, that the failure to provide such notice shall not limit or impair the
rights of the Senior Parties hereunder or under the Financing Documents.

         (c) Each Senior Party hereby acknowledges and agrees that all funds
held by the Trustee in accordance with Article 5 of the Indenture are held for
the benefit of the Bondholders and that the Trustee shall hold such funds solely
for the benefit of such Bondholders.

         (d) Each Senior Party hereby acknowledges and agrees that all funds
held in the Debt Service Reserve Account by the Collateral Agent in accordance
with this Agreement are held for the benefit of the Trustee (on behalf of the
Bondholders) and that the Collateral Agent shall hold such funds solely for the
benefit of such Persons.

         (e) Each Senior Party hereby acknowledges and agrees that any DSR
Letter of Credit held by the Collateral Agent in accordance with this Agreement
is held for the benefit of the Trustee (on behalf of the Bondholders) and for
the benefit of the DSR LOC Provider to the extent of its interest in such DSR
Letter of Credit and that the Collateral Agent shall hold such letter of credit
(and the proceeds thereof) solely for the benefit of such Persons.



                                       9


         (f) Each Senior Party hereby acknowledges and agrees that all funds
held in the DSR LOC Reimbursement Fund or the CP LOC Reimbursement Fund by the
Collateral Agent in accordance with this Agreement are held for the benefit of
the DSR LOC Provider or CP LOC Provider, as the case may be, and that the
Collateral Agent shall hold such funds solely for the benefit of such Persons.

         (g) Each Senior Party hereby acknowledges and agrees that the
Collateral Agent, subject to Section 5.2(c) and (e), shall administer the
Collateral in the manner contemplated by the Security Documents and this
Agreement and the Collateral Agent shall exercise, as directed by the Required
Senior Parties in Senior Party Certificates in accordance with Section 2.3(a)
such rights and remedies with respect to the Collateral (including the curing of
defaults under the Transaction Documents) as are granted to it under the
Security Documents, this Agreement and Applicable Law. No Senior Party and no
class or classes of Senior Parties shall have any right (i) to direct the
Collateral Agent to take any action in respect of the Collateral other than in
accordance with Section 2.3(a) or (ii) to take any action with respect to the
Collateral (A) independently of the Collateral Agent or (B) other than to direct
the Collateral Agent in writing to take action in accordance with Section
2.3(a); provided, however, that nothing in this Section 2.3(g) shall be deemed
to limit the ability of any Senior Party to take any action in accordance with
Section 2.3(i).

         (h) Each of the Company and each Senior Party covenants and agrees
that, upon the occurrence and during the continuation of a Trigger Event, the
Collateral Agent shall be entitled, as instructed by the Required Senior Parties
in Senior Party Certificates in accordance with Section 2.3(a), to give notices
or instructions that the Company would otherwise be entitled to give under this
Agreement.

         (i) From time to time during the continuation of a Trigger Event, the
Collateral Agent shall, as instructed by the Required Senior Parties in Senior
Party Certificates in accordance with Section 2.3(a), direct the Depositary Bank
to render an accounting of the current balance of each Project Account or other
amounts or funds administered by the Depositary Bank under this Agreement, and
the Depositary Bank agrees to render the same, subject to the terms, conditions
and protections contained in this Agreement.

         (j) The Company covenants and agrees that it shall not take any action
that would prohibit or impair the ability of the Collateral Agent from
participating in any objection to any foreclosure or similar proceeding
instituted by a junior lienor against the Company; provided, however, that
nothing in this Section 2.3(j) shall, or shall be deemed to, affect the
relationship among the Senior Parties or the relationship between the Senior
Parties and the Collateral Agent, nor shall anything in this Section 2.3(j)
affect any representation, warranty, covenant or agreement of any Senior Party
in this Agreement.

         (k) The Company covenants and agrees that it shall send to the
Collateral Agent on or before five (5) days prior to each Bond Payment Date an
Officer's Certificate signed by an Authorized Representative of the Company
setting forth (i) the names of each Senior Party as of the date of the
certificate, (ii) the principal amount of the Financing Liabilities owed to each
such



                                       10



Senior Party as of the date of the certificate and (iii) the unutilized
outstanding commitments of each Senior Party to extend credit to the Company as
of the date of the certificate, including, but not limited to, (A) the Stated
Amount of the DSR Letter of Credit and the CP Letter of Credit and (B) the
obligation of the DSR LOC Provider to issue the DSR Letter of Credit, to
reinstate the DSR Letter of Credit upon the reimbursement of drawings thereunder
and increase the amount of the DSR Letter of Credit from time to time by reason
of an increase in the DSRA Required Balance. The Collateral Agent shall be
entitled to rely on the information contained in such certificate.

         (l) Notwithstanding the foregoing provisions of this Article II, each
Senior Party individually shall be authorized to cure any default of the Company
under any Project Contract in accordance with the consent to assignment executed
in connection with such Project Contract; provided, however, that funds advanced
in connection with such cure shall not constitute Senior Debt unless such funds
would otherwise satisfy the requirements for the issuance of Senior Debt.

         (m) Each Senior Party hereby acknowledges and agrees that if (i) there
is an Event of Default under the Indenture and such Event of Default is not
caused directly or indirectly by a default or event of default under the Power
Purchase Agreement, (ii) the Collateral Agent receives the written request of
the Required Senior Parties specified in Section 2.3(a), and (iii) the Trustee
has been directed by the required Bondholders to declare the aggregate principal
amount of the Outstanding Bonds, all interest accrued and unpaid thereon and all
premium payable thereon in accordance with the terms of the Indenture
immediately due and payable, the Collateral Agent at the direction of the
Required Senior Parties shall notify the Power Purchaser in writing at the
address provided in the Power Purchase Agreement of the opportunity to purchase
the Facility for an amount equal to the greater of (x) the Fair Market Value of
the Facility and (y) all Financing Liabilities due and owing to the Senior
Parties and any Subordinated Debt Provider. If the Power Purchaser has not
within 90 days of the date of such notice provided the Collateral Agent with a
binding written notice of its intent to purchase the Facility for such amount,
the Collateral Agent shall no longer have any obligation under this paragraph.
If the Power Purchaser offers within such period to purchase the Facility for
such amount within 120 days after the expiration of such 90 day period, the
Collateral Agent shall take such actions as required to consummate such sale
promptly as directed by the Required Senior Parties in Senior Party
Certificates.

         SECTION 2.4 Rights of Senior Parties.

         The Senior Parties and the Collateral Agent (upon receipt of Senior
Party Certificates from the Required Senior Parties) may, at any time and from
time to time, without any consent of or notice to any Subordinated Debt
Providers, (i) amend in any manner any Security Document or any agreement under
which any of the Financing Liabilities is outstanding in accordance with the
terms thereof, (ii) sell, exchange, release, not perfect and otherwise deal with
any property at any time pledged, assigned or mortgaged to secure the Financing
Liabilities in accordance with the Security Documents, (iii) release anyone
liable in any manner under or in respect of the Financing Liabilities, (iv)
exercise or refrain from exercising any rights against the Company and



                                       11



others and (v) apply any sums from time to time received to payment or
satisfaction of the Financing Liabilities.

         SECTION 2.5 Certain Amendments.

         Notwithstanding anything to the contrary in this Agreement or any
Security Document, if any consent or direction of the Required Secured Parties
is necessary in order for the Collateral Agent to exercise any rights or
remedies under any of the Security Documents or this Agreement, or to amend,
modify or supplement, give any consent under, or waive any provision of, any of
the Security Documents or this Agreement, and if any such exercise of rights or
remedies, or any such amendment, modification, supplement, consent or waiver
(either alone or together with each then effective amendment, modification,
supplement, consent or waiver not previously approved in accordance with this
paragraph by the CP LOC Provider or the DSR LOC Provider, as the case may be)
could reasonably be expected to have a material adverse effect on the CP LOC
Provider or the DSR LOC Provider (which material adverse effect is materially
different from the effect with respect to other Senior Parties), the Collateral
Agent shall not accept such consent or direction from the Required Senior
Parties unless the CP LOC Provider or the DSR LOC Provider, as the case may be,
shall have received written notice of such proposed consent or direction at
least fifteen days prior to the effectiveness thereof, and the CP LOC Provider
or the DSR LOC Provider, as the case may be, shall have approved such amendment,
modification or supplement, consent or waiver (which approval shall not be
unreasonably withheld).

                                  ARTICLE III

                                    ACCOUNTS

         SECTION 3.1 Establishment of Project Accounts.

         The Collateral Agent hereby confirms that it has established with the
Depositary Bank at its office at the address listed in Section 7.4, New York,

         (i)    Construction Account;

         (ii)   Revenue Account;

         (iv)   Debt Service Reserve Account;

         (v)    DSR LOC Reimbursement Fund;

         (vi)   CP LOC Reimbursement Fund;

         (vii)  Restoration Account;



                                       12


         (viii) Major Maintenance Reserve Account;

         (ix)   Fuel Conversion Payment Volume Rebate Account;

         (x)    Subordinated Debt Account; and

         (xi)   Distribution Account.

         All amounts from time to time held in each Project Account shall be
held (a) in the name of the Collateral Agent subject to the lien and security
interest of the Collateral Agent for the benefit of the Senior Parties or
certain of them as set forth herein and (b) in the custody of the Depositary
Bank for and on behalf of the Collateral Agent for the purposes and on the terms
set forth in this Agreement. All such amounts shall constitute a part of the
Collateral and shall not constitute payment of any Indebtedness or any other
obligation of the Company until applied as hereinafter provided.

         SECTION 3.2 Investment of Funds in the Project Accounts.

         (a) Amounts deposited in the Project Accounts (and each subaccount
thereof) and each other account or fund created hereunder (unless expressly
stated otherwise), at the written request and direction of the Company, shall be
invested by the Collateral Agent in Permitted Investments. Such investments
shall mature in such amounts and not later than such times as may be necessary
to provide funds when needed to make payments from such funds as provided in
this Agreement. Net interest or gain received from such investments shall be
applied as provided in this Agreement.

         (b) So long as an outstanding balance shall remain in the Project
Accounts or any other account or fund created hereunder, the Collateral Agent
shall provide the Company, the DSR LOC Provider and the CP LOC Provider with
statements by the tenth (10th) Business Day of each month showing the amount of
all receipts, the net investment income or gain received and collected, all
disbursements and the amount then available as of the last Business Day of the
prior calendar month in the Project Accounts (and each subaccount thereof) and
each other account or fund created hereunder. The Depositary Bank agrees to
provide the Collateral Agent with such information as it may reasonably have
available to it in order to permit the Collateral Agent to provide such
statements in accordance with the requirements hereof.

         SECTION 3.3 Valuation and Sale of Investments.

         (a) Obligations purchased as an investment of funds in any Project
Account or any other separate account or fund created under the provisions
hereof shall be deemed at all times to be a part of such account or fund and,
unless otherwise specified herein, any profit realized from the liquidation of
such investment shall be credited to such Project Account or such other separate
account or fund created hereunder, and any loss resulting from the liquidation
of such investment shall be charged to the respective Project Account or such
other separate account or fund.



                                       13


         (b) The Collateral Agent shall determine the value of all investments
in any of the Project Accounts or the Bond Payment Account as of the last
Business Day of each month, with any deficit in any account balance to be funded
from Project Revenues in accordance with Section 3.3, and any investments valued
in excess of the amounts required to be on deposit in an account shall be
liquidated and the amount of such excess shall be deposited in the Revenue
Account for application in accordance with Section 3.10.

         (c) The Collateral Agent shall determine the value of all investments
in the Debt Service Reserve Account in accordance with Section 3.12.

         (d) In computing the amount of any funds in any Project Account, or
other separate account or fund created under the provisions hereof for any
purpose provided in this Agreement, obligations purchased as an investment of
funds therein shall be valued at the market value of such obligations, exclusive
of accrued interest; provided, however, that if there is no readily determinable
market value for such obligations, the value of such obligations shall be
determined with reference to the acquisition price of such obligations, plus
accrued but unpaid interest.

         (e) The Depositary Bank agrees to provide the Collateral Agent with
such information as it may reasonably have available to it in order to permit
the Collateral Agent to make such determinations and transfers as may be
required by this Section 3.3.

         SECTION 3.4 Possession of Accounts; Liquidation.

         (a) Each of the Project Accounts shall at all times be in the exclusive
possession of the Depositary Bank acting for and on behalf of the Collateral
Agent acting for and on behalf of the Senior Parties.

         (b) Notwithstanding any provision hereof to the contrary, if a Trigger
Event shall have occurred and be continuing, the Collateral Agent shall promptly
liquidate all amounts in the Project Accounts and all related investments and
distribute all such monies so received in accordance with Section 4.1.

         SECTION 3.5 The Depositary Bank; Limited Company Rights.

         (a) The Depositary Bank.

                  (i) Establishment of Securities Accounts. The Depositary Bank
         hereby agrees and confirms that (A) the Depositary Bank has established
         the Project Accounts as set forth in Section 3.1, (B) each Project
         Account is and will be maintained as a "securities account" (within the
         meaning of Section 8-501 of the UCC), (C) the Company is the
         "entitlement holder" (within the meaning of Section 8-102(a)(7) of the
         UCC) in respect of the "financial assets" (within the meaning of
         Section 8-102(a)(9) of the UCC) credited to the Project Accounts, (D)
         all property delivered to the Depositary Bank pursuant to the
         Transaction Documents or this Agreement will be held by the Depositary
         Bank and promptly credited to a Project Account by an appropriate entry
         in its records in accordance with this Agreement, (E) all "financial
         assets" (within the meaning of Section



                                       14







         8-102(a)(9) of the UCC) in registered form or payable to or to the
         order of and credited to any Project Account shall be registered in the
         name of, payable to or to the order of, or endorsed to, the Depositary
         Bank or in blank, or credited to another securities account maintained
         in the name of the Depositary Bank, and in no case will any financial
         asset credited to any Project Account be registered in the name of,
         payable to or to the order of, or endorsed to, the Company except to
         the extent the foregoing have been subsequently endorsed by the Company
         to the Depositary Bank or in blank and (F) the Depositary Bank shall
         not change the name or account number of any Project Account without
         the prior written consent of the Collateral Agent.

                  (ii) Financial Assets Election. The Depositary Bank agrees
         that each item of property (excluding cash, but including any security,
         instrument or obligation, share, participation, interest or other
         property whatsoever) credited to any Project Account shall be treated
         as a "financial asset" within the meaning of Section 8-102(a)(9) of the
         UCC.

                  (iii) Entitlement Orders. If at any time the Depositary Bank
         shall receive any "entitlement order" (within the meaning of Section
         8-102(a)(8) of the UCC) or any other order from the Collateral Agent
         acting in accordance with this Agreement directing the transfer or
         redemption of any financial asset relating to the Project Accounts, the
         Depositary Bank shall comply with such entitlement order or other order
         without further consent by the Company or any other Person. The parties
         hereto hereby agree that the Collateral Agent shall have "control"
         (within the meaning of Section 8-106(d) of the UCC) of the Company's
         "security entitlement" (within the meaning of Section 8-102(a)(17) of
         the UCC) with respect to the financial assets credited to the Project
         Accounts and the Company hereby disclaims any entitlement to claim
         "control" of such "security entitlement".

                  (iv) Subordination of Lien; Waiver of Set-off. If the
         Depositary Bank has or subsequently obtains by agreement, operation of
         law or otherwise a lien or security interest in any Project Account or
         any security entitlement credited thereto, the Depositary Bank agrees
         that such lien or security interest shall be subordinate to the lien
         and security interest of the Collateral Agent. The financial assets
         standing to the credit of the Project Accounts will not be subject to
         deduction, set-off, banker's lien, or any other right in favor of any
         Person other than the Collateral Agent in its capacity as such (except
         that the face amount of any checks which have been credited to any
         Project Account but are subsequently returned unpaid because of
         uncollected or insufficient funds).

                  (v) No Other Agreements. The Depositary Bank and the Company
         have not entered into any agreement with respect to the Project
         Accounts or any financial assets credited to any Project Account other
         than this Agreement and the other Security Documents. The Depositary
         Bank has not entered into any agreement with the Company or any other
         Person purporting to limit or condition the obligation of the
         Depositary Bank to comply with entitlement orders originated by the
         Collateral Agent in accordance with this Section 3.5. In the event of
         any conflict between this Section 3.5 or any other


                                       15


         Security Document or any other agreement now existing or hereafter
         entered into, the terms of this Section 3.5 shall prevail.

                  (vi) Notice of Adverse Claims. Except for the claims and
         interest of the Collateral Agent and the Company in each of the Project
         Accounts, the Depositary Bank does not know of any claim to, or
         interest in, any Project Account or in any financial asset credited
         thereto. If any Person asserts any lien, encumbrance or adverse claim
         (including any writ, garnishment, judgment, warrant of attachment,
         execution or similar process) against any Project Account or in any
         financial asset credited thereto, the Depositary Bank will promptly
         notify the Collateral Agent and the Company thereof.

                  (vii) Rights and Powers of the Collateral Agent. The rights
         and powers granted by the Collateral Agent to the Depositary Bank have
         been granted in order to perfect its lien and security interests in the
         Project Accounts, are powers coupled with an interest and will neither
         be affected by the bankruptcy of the Company nor the lapse of time.

                  (viii) Choice of Law. Both this Agreement and each Project
         Account (including all security entitlements relating thereto) shall be
         governed by the law of the State of New York. Regardless of any
         provision in any other agreement, for purposes of the UCC, the
         "securities intermediary's jurisdiction" of the Depositary Bank with
         respect to the Project Accounts is the State of New York.

         (b) Limited Company Rights. The Company shall not have any rights
against or to monies held in the Project Accounts, as third-party beneficiary or
otherwise or any right to direct the Depositary Bank or the Collateral Agent to
apply or transfer monies in any Project Account, except the right to receive or
make requisitions of monies held in the Project Accounts, as permitted by this
Agreement and to direct the investment of monies held in the Project Accounts as
permitted by Section 3.2. Except as expressly provided in this Agreement, in no
event shall any amounts or Permitted Investments deposited in or credited to any
Project Account be registered in the name of the Company, payable to the order
of the Company or specially endorsed to the Company except to the extent that
the foregoing have been specially endorsed to the Collateral Agent or in blank.

         SECTION 3.6 Advances.

         (a) Notwithstanding any other provision hereof to the contrary, the
Company may, by delivering an Officer's Certificate to the Collateral Agent,
withdraw funds on deposit in or credited to any of the Available Accounts
("Advances"); provided, however, that, at the time of the making of such
Advance, (i) no Default or Event of Default shall have occurred and be
continuing and the Officer's Certificate of the Company shall so certify and
(ii) the Company's obligations to repay such Advances shall be supported by
Acceptable Credit Support. The Collateral Agent may conclusively rely on such
Officer's Certificate certifying that all conditions for withdrawals from the
Available Accounts have been met.

         (b) The Company shall repay immediately or cause to be repaid any
Advances to the extent that the funds on deposit in such Available Accounts are,
on the Business Day next




                                       16



preceding the day on which such funds are to be withdrawn or transferred from
such Available Accounts pursuant to this Article III, insufficient to make the
necessary withdrawals and transfers. In addition, the Company shall cause to be
repaid immediately the aggregate amount of all Advances upon the occurrence of
(i) a default in the payment of principal of, premium, if any, or interest on
the Bonds or pursuant to the DSR LOC Reimbursement Agreement, the CP LOC
Reimbursement Agreement or any working capital facility, (ii) any Event of
Default, (iii) any default by an Acceptable Credit Provider in respect of its
obligations under its Acceptable Credit Support or (iv) the failure of the

such repayment is required to be made as directed by the Company in an Officer's
Certificate.

         (c) If an Advance is repaid but the Acceptable Credit Support in

of a written request of the Company, shall, and hereby is directed to, promptly
execute such documents and agreements as the Company may reasonably request in

continuing until the Collateral Agent determines that such Trigger Event is no
longer continuing or the Required Senior Parties give instructions to the
Collateral Agent as to application of funds.

                                       18

         SECTION 3.11 Operating and Maintenance Account.

         (a) The Operating and Maintenance Account shall be funded from funds

         SECTION 3.12 Debt Service Reserve Account.

         (a) The Company shall deliver, or cause to be delivered, to the
Collateral Agent the DSR Letter of Credit upon the earlier to occur of (i) the
Commercial Operation Date, (ii) the Guaranteed Completion Date, or (iii) the
Date Certain. The Collateral Agent shall hold the DSR Letter of Credit as
security agent for the Trustee and the DSR LOC Provider to the extent of its
interest therein. The Collateral Agent is hereby authorized to submit sight
drafts and other required documentation under the DSR Letter of Credit, in each
case, when and to the extent permitted under the DSR Letter of Credit and for
the purposes specified in this Section 3.12.

         (b) Upon the occurrence of the Commercial Operation Date, the Debt
Service Reserve Account, shall be funded, if necessary after taking into account
the Outstanding Amount of the DSR Letter of Credit, from monies available in the
Construction Account for such purpose in accordance with Section 3.9 in an
amount up to the DSRA Required Balance.



                                       22


         (c) Subsequent to the Commercial Operation Date, the Debt Service
Reserve Account shall be funded, if necessary, from monies transferred from the
Revenue Account as and when specified in Section 3.10.

         (d) Notwithstanding any other provision hereof to the contrary, when
determining (i) the amount, if any, required to be deposited (or the amount so
required to be deposited) into the Debt Service Reserve Account from time to
time or (ii) whether the Debt Service Reserve Account has deposited therein the
DSRA Required Balance, amounts on deposit in the Debt Service Reserve Account
shall be aggregated with the amount available to be drawn on the DSR Letter of
Credit.

         (e) When there are insufficient monies in the Bond Payment Account on
any Bond Payment Date to pay the interest or principal then due on the Bonds,
the Collateral Agent shall, upon receipt prior to such Bond Payment Date of an
Officer's Certificate of the Company and as directed on such certificate, in the
following order of priority: first, withdraw monies on deposit in the Debt
Service Reserve Account; and second, draw on the DSR Letter of Credit in
accordance with the terms and provisions thereof up to the amount available for
such purpose thereunder, in each case, to the extent necessary to make such
interest or principal payment on the Bonds and transfer such monies to the
Trustee for deposit in the Bond Payment Account for application against such
payment.

         (f) If the Collateral Agent receives a written notice from the Company
stating that there has been a reduction in the long-term debt rating of the DSR
LOC Provider below the Required Rating, or if a Responsible Officer of the
Collateral Agent otherwise becomes aware of such reduction, and the DSR Letter
of Credit has not been replaced within the time period specified therefor, the
Collateral Agent shall draw on the DSR Letter of Credit in the amount necessary
to fund the Debt Service Reserve Account up to the DSRA Required Balance (as
certified in an Officer's Certificate of the Company delivered to the Collateral
Agent, calculated without aggregating therewith the amount available to be drawn
under the DSR Letter of Credit but taking into account amounts then on deposit
in or credited to the Debt Service Reserve Account), whereupon the Collateral
Agent shall deposit the proceeds of such drawing in the Debt Service Reserve
Account, and the DSR Letter of Credit shall thereupon automatically terminate.
The Company shall give the notice specified in this Section 3.12(f) within three
(3) Business Days of its actual knowledge of the event giving rise to such
notice.

         (g) If the Collateral Agent receives a written notice from the DSR LOC
Provider substantially in the form of Annex 2 to the DSR Letter of Credit,
stating that the DSR LOC Provider shall terminate the DSR Letter of Credit on
the date specified in such notice (which termination date shall be no sooner
than 60 days following the giving of such notice), the Collateral Agent shall,
within three (3) Business Days of receipt of such notice, draw on the DSR Letter
of Credit in an amount equal to the amount necessary to fund the Debt Service
Reserve Account up to the DSRA Required Balance (calculated without aggregating
therewith the amount available to be drawn under the DSR Letter of Credit),
whereupon the Collateral Agent shall deposit the proceeds of such drawing in the
Debt Service Reserve Account, and the DSR Letter of Credit shall thereupon
automatically terminate.



                                       23


         (h) If a Trigger Event shall have occurred and be continuing and the
Collateral Agent has received the written request of the Required Senior Parties
contained in Senior Party Certificates and such notice has not been rescinded,
then the Collateral Agent, upon receipt of an Officer's Certificate of the
Company setting forth the DSRA Required Balance (calculated without aggregating
therewith the amount available to be drawn under the DSR Letter of Credit),
shall draw on the DSR Letter of Credit in an amount equal to the amount
necessary to fund the Debt Service Reserve Account up to the DSRA Required
Balance (calculated as described in the immediately preceding parenthetical),
whereupon the Collateral Agent shall distribute the proceeds of such drawing,
together with other amounts available in the Debt Service Reserve Account, to
the Trustee, and the DSR Letter of Credit shall thereupon automatically
terminate. The failure of the Collateral Agent to receive the written request of
the Required Senior Parties contained in Senior Party Certificates shall not
limit the rights or obligations of the Collateral Agent otherwise provided for
herein.

         (i) If, subsequent to the Commercial Operation Date, monies transferred
to the DSR LOC Provider pursuant to Section 3.10(b) third are insufficient to
repay the interest on any DSR LOC Loans due or becoming due on the first day of
such month, the Collateral Agent, upon receipt of a certificate of an Authorized
Officer of the DSR LOC Provider notifying the Collateral Agent of the existence,
and setting forth the amount, of such shortfall, within two (2) Business Days of
receipt of such certificate shall draw on the DSR Letter of Credit in an amount
equal to the amount of such shortfall and transfer such amount to the DSR LOC
Provider in payment (in whole or part) of such interest on such DSR LOC Loans.
Notwithstanding the foregoing, in no event shall any draw on the DSR Letter of
Credit under this Section 3.12(i) individually or in the aggregate with all
other such draws less draws previously reimbursed exceed an amount (the
"Interest Portion") equal to six (6) months of interest on the Maximum Stated
Amount of the DSR Letter of Credit computed at a rate per annum equal to (x) 2%
plus (y) the three-month LIBOR rate as in effect two Business Days prior to the
date of issuance of the DSR Letter of Credit plus (z) 50 basis points; provided,
however, that to the extent amounts available to be drawn under the DSR Letter
of Credit have been reinstated due to reimbursement of prior draws on the DSR
Letter of Credit, draws on the DSR Letter of Credit under this Section 3.12(i)
may equal (in the aggregate with all other such draws) the sum of (x) the
Interest Portion plus (y) an amount equal to the aggregate amount of all
reinstatements of amounts available to be drawn under the DSR Letter of Credit
allocable to prior reimbursements of draws on the DSR Letter of Credit under
this Section 3.12(i) (such allocation shall be determined by multiplying the
aggregate amount of prior reimbursements of draws by a fraction, the numerator
of which is the aggregate amount of drawings under the DSR Letter of Credit
described in this paragraph and the denominator of which is the aggregate amount
of drawings under the DSR Letter of Credit for all purposes).

         (j) Unless the DSR Letter of Credit is not extended or replaced or
unless there has been a DSR LOC Event of Default all as described under the DSR
LOC Reimbursement Agreement, amounts available for drawing under the DSR Letter
of Credit shall be reinstated immediately to the extent of any reimbursement of
principal in respect of DSR LOC Loans (but not DSR LOC Term Loans or DSR Bonds).



                                       24


         (k) If the Company and the DSR LOC Provider shall agree to issue or
reinstate the DSR Letter of Credit in an amount that, when aggregated with cash
on deposit in the Debt Service Reserve Account, would exceed the DSRA Required
Balance (the amount of such excess being referred to hereinafter as the "Excess
Amount"), the Collateral Agent shall, within two (2) Business Days of receipt by
the Collateral Agent of (i) such reissued or reinstated DSR Letter of Credit and
(ii) an Officer's Certificate of the Company, transfer an amount equal to the
Excess Amount to the Revenue Account for application in accordance with clause
eleventh of Section 3.10; provided, that the amount of the DSR Letter of Credit
may not exceed the DSRA Required Balance.

         SECTION 3.13 Major Maintenance Reserve Account.

         (a) The Major Maintenance Reserve Account shall be funded (i) from
funds transferred by the Collateral Agent from the Construction Account pursuant
to Section 3.9 and (ii) on a monthly basis pursuant to Section 3.10. The Company
shall specify funding of the Major Maintenance Reserve Account in light of the
Annual Budget and taking into account expected costs of major maintenance,
including costs under the Maintenance Services Agreement not included as an
Operating and Maintenance Cost and major maintenance intervals.

         (b) Upon receipt by the Collateral Agent of an Officer's Certificate of
the Company detailing the amounts to be paid, the Collateral Agent shall
transfer funds in the Major Maintenance Reserve Account to the Company or to
whomsoever the Company directs for application to the payment of major
maintenance costs and expenses of the Facility that are not otherwise paid as
Operating and Maintenance Costs pursuant to Section 3.11.

         (c) If Project Revenues are insufficient to pay Operating and
Maintenance Expenses and debt service, the Company may, through the delivery of
an Officer's Certificate to that effect, direct the Collateral Agent to apply
funds in the Major Maintenance Reserve Account to the payment of Operating and
Maintenance Expenses and debt service.

         SECTION 3.14 Distribution Account.

         (a) The Distribution Account shall be funded from funds transferred
from the Revenue Account in accordance with Section 3.10.

         (b) On any date on which the conditions set forth below (the
"Distribution Conditions") are satisfied, funds on deposit in or credited to the
Distribution Account may be distributed to, or as directed by, the Company for
the payment of Affiliate Subordinated Debt, the making of distributions to the
holders of ownership interests in the Company or any other lawful purpose, upon
receipt by the Collateral Agent of an Officer's Certificate of the Company
requesting such a distribution and certifying that:

                  (i) all of the Project Accounts described in Section 3.10(b)
         and the Bond Payment Account shall be funded to their required levels;



                                       25


                  (ii) no (A) Default or Event of Default under the Indenture,
         (B) default or event of default under the DSR LOC Reimbursement
         Agreement, (C) default or event of default under any CP LOC
         Reimbursement Agreement or (D) default under any working capital
         arrangements, if any, shall have occurred and be continuing;

                  (iii) the Commercial Operation Date has occurred and at least
         one complete fiscal quarter thereafter has elapsed;

         as one period, is greater than or equal to 1.2 to 1 and (B) based on
         projections prepared by the Company on a reasonable basis, the
         projected Senior Debt Service Coverage Ratio for the succeeding four

         is to be made) (or, with respect to any date within the twelve
         (12)-month period prior to the end of the PPA Term, the number of
         complete fiscal quarters, if any, until the end of the PPA Term) is
         projected to be greater than or equal to 1.2 to 1; and

                  (v) if the requested distribution is to be made on or after

         respect to such period occurring prior to the end of the PPA Term) and
         (B) based on projections prepared by the Company on a reasonable basis,
         the projected Senior Debt Service Coverage Ratio for the succeeding
         eight (8) fiscal quarters (including the fiscal quarter in which such
         distribution is to be made) (or, with respect to any date within the
         twenty-four (24)-month period prior to the Final Maturity Date, the
         number of complete fiscal quarters, if any, until such Final Maturity
         Date), in each case measured as one period, is projected to be greater
         than or equal to 1.70 to 1 (or 1.2 to 1 with respect to such period
         occurring prior to the end of the PPA Term), each as certified by an
         authorized officer of the Company; provided, however, that,

                           (A) if distributions are blocked because the Company
                  fails to satisfy the conditions of clause (v)(B) above, then
                  in lieu of the coverage ratio test set forth in such clause,
                  the projected Senior Debt Service Coverage Ratio through the
                  Final Maturity Date, measured as one period, shall be 1.70 to
                  1 in order to satisfy such clause (v)(B) in respect of amounts
                  then on deposit in the Distribution Account;

                           (B) for purposes of calculating the projected Senior
                  Debt Service Coverage Ratios in clauses (v)(B) above, the

                  Forecast furnished to the Trustee, in each case, during the
                  relevant period of calculation or (y) if and to the extent
                  that electricity sales during the relevant period of
                  calculation are made pursuant to one or more power sales
                  agreements at prices other than prices which are by their
                  terms market prices, the electricity prices under such power
                  sales agreements and (2) for gas prices, either (x) the gas
                  prices forecasted in the most recent Independent Forecast
                  furnished to the Trustee, in each case, during the relevant
                  period of calculation or (y) if and to the extent that gas
                  purchases during the relevant period of calculation are made
                  pursuant to one or more gas purchase agreements at prices
                  other than prices which are by their terms market prices, the
                  gas prices under such gas purchase agreements;

                           (C) if, and to the extent that, (x) at least 75% of
                  the Facility Capacity is subject to one or more power sales
                  agreements on terms (other than pricing) substantially similar
                  to the Power Purchase Agreement (but excluding the provision
                  for gas to be supplied for fuel conversion services by the
                  Power Purchaser) or on commercially reasonable terms (other
                  than pricing) typical of power sales agreements entered into
                  at such time for the same term, in each case with a term of
                  not less than one (1) year during the relevant period of
                  calculation, and (y) at least 75% of the gas supply for the

                  term, in each case with a term of not less than one (1) year
                  during the relevant period of calculation (compliance with
                  such requirements to be certified by the Company), then clause
                  (v) above shall be deemed satisfied, if the Senior Debt
                  Service Coverage Ratio and the projected Senior Debt Service
                  Coverage Ratio referred to in such clause (v) are each equal
                  to or greater than 1.30 to 1 for the portions of the time
                  periods referred to in such clause (v) in which such
                  agreements were or are to be in effect, as certified by the
                  Company; and

                           (D) if amounts on deposit in or credited to the
                  Revenue Account are insufficient to make the transfers
                  described in priorities first through sixth in Section 3.10,
                  amounts on deposit in or credited to the Distribution Account
                  will be transferred to the Revenue Account to the extent
                  necessary and applied in accordance with Section 3.10.

         SECTION 3.15 Restoration Account.

         (a) All Casualty Proceeds and Eminent Domain Proceeds shall be
deposited into the Restoration Account. Subject to Sections 3.15(d) and (e), the
Collateral Agent shall apply the amounts in the Restoration Account as directed
in writing by the Company to the payment, or reimbursement to the extent the
same have been paid or satisfied by the Company, of the costs of rebuilding,
repair and restoration of the Facility or any part thereof that has been
affected by an Event of Loss or an Event of Eminent Domain.



                                       27


         (b) The Collateral Agent is hereby authorized to disburse from the
Restoration Account the amount required to be paid for the repair or replacement
of the Facility or any part thereof as specified in Section 3.15(a). The
Collateral Agent is hereby authorized and directed to issue its checks or
transfer funds electronically for each disbursement from the Restoration
Account, upon receipt of a Restoration Certificate signed by an Authorized
Representative of the Company and approved by the Independent Engineer;
provided, however, that no such approval of the Independent Engineer shall be
required if less than $5,000,000 is requested pursuant to such requisition or
requisitions in any one Fiscal Year. The Collateral Agent shall be entitled to
rely on all certifications and statements in such Restoration Certificate. The
Collateral Agent shall keep and maintain adequate records pertaining to the
Restoration Account and all disbursements therefrom and shall file an accounting
thereof with the Company and the Independent Engineer within three months
following the last business day of each Fiscal Year.

         (c) If an Event of Loss or an Event of Eminent Domain shall occur with
respect to any Collateral, the Company shall (i) diligently pursue all its
rights to compensation against any Person with respect to such Event of Loss or
Event of Eminent Domain, (ii) in the reasonable judgment of the Company,
compromise or settle any claim against any Person with respect to such Event of
Loss or Event of Eminent Domain and (iii) hold all amounts of Casualty Proceeds
or Eminent Domain Proceeds (including instruments) received in respect of any
Event of Loss or Event of Eminent Domain (after deducting all reasonable
expenses incurred by it in litigating, arbitrating, compromising or settling any
claims) in trust for the benefit of the Collateral Agent segregated from other
funds of the Company and will promptly transfer to the Collateral Agent for
deposit in the Restoration Account such Casualty Proceeds or Eminent Domain
Proceeds.

         (d) If either an Event of Loss or an Event of Eminent Domain shall
occur, as soon as reasonably practicable but no later than the date of receipt
by the Company or the Collateral Agent of Eminent Domain Proceeds or Casualty
Proceeds, as the case may be, the Company shall make a reasonable good faith
determination as to whether (i) the Facility or any portion thereof can be
rebuilt, repaired or restored to permit operation of the Facility or a portion
thereof on a commercially feasible basis and (ii) the Casualty Proceeds or the
Eminent Domain Proceeds, as the case may be, together with any other amounts
that are available to the Company for such rebuilding, repair or restoration,
are sufficient to permit such rebuilding, repair or restoration of the Facility
or a portion thereof, including the making of all required payments of interest
and principal on the Company's Debt during such rebuilding, repair or
restoration. The determination of the Company shall be evidenced by a
Certificate as to Redemption filed with the Collateral Agent which, in the event
the Company determines that the Facility or a portion thereof can be rebuilt,
repaired or restored to permit operation thereof on a commercially feasible
basis and that the Casualty Proceeds or the Eminent Domain Proceeds, as the case
may be, together with any other amounts that are available to the Company for
such rebuilding, repair or restoration, are sufficient, shall also set forth a
reasonable good faith estimate by the Company of the total cost of such
rebuilding, repair or restoration. The Company shall deliver to the Collateral
Agent at the time it delivers the Certificate as to Redemption referred to above
a certificate of the Independent Engineer, dated the date of the Certificate as
to Redemption, stating that, based upon reasonable investigation and review of
the determination made by the



                                       28





Company, the Independent Engineer believes the determination and the estimate of
the total cost set forth in the Certificate as to Redemption to be reasonable.

         (e)      (i) If, following an Event of Loss or an Event of Eminent
         Domain, the determination is made pursuant to Section 3.15(d) above
         that the Facility cannot be rebuilt, repaired or restored to permit
         operation on a commercially feasible basis or that the Casualty
         Proceeds or the Eminent Domain Proceeds, together with any other
         amounts that are available to the Company for such rebuilding, repair
         or restoration, are not sufficient to permit such rebuilding, repair or
         restoration, all of the Casualty Proceeds or the Eminent Domain
         Proceeds, as the case may be, shall be distributed in accordance with
         Section 4.2(a).

                  (ii) If, following an Event of Loss or an Event of Eminent
         Domain, the determination is made pursuant to Section 3.15(d) above
         that the entire Facility can be rebuilt, repaired or restored to permit
         operation on a commercially feasible basis and that the Casualty
         Proceeds or the Eminent Domain Proceeds, together with any other
         amounts that are available to the Company for such rebuilding, repair
         or restoration, are sufficient to permit such rebuilding, repair or
         restoration, all of the Casualty Proceeds or the Eminent Domain
         Proceeds, as the case may be, together with such other amounts as are
         available to the Company for such rebuilding, repair or restoration,
         shall be deposited in the Restoration Account in accordance with
         Section 3.15(a) and applied in accordance with Section 3.15(b).

                  (iii) If, following an Event of Loss or an Event of Eminent
         Domain, the determination is made pursuant to Section 3.15(d) above
         that a portion of the Facility can be rebuilt, repaired or restored to
         permit operation on a commercially feasible basis and that the Casualty
         Proceeds or the Eminent Domain Proceeds, together with any other
         amounts that are available to the Company for such rebuilding, repair
         or restoration, are sufficient to permit such rebuilding, repair or
         restoration, (A) an amount equal to the estimate of the total cost of
         such rebuilding, repair or restoration set forth in the Certificate as
         to Redemption filed with the Collateral Agent pursuant to Section
         3.15(d) above shall be deposited in the Restoration Account in
         accordance with Section 3.15(a) and applied in accordance with Section
         3.15(b) and (B) the amount, if any, by which all of the Casualty
         Proceeds or the Eminent Domain Proceeds, as the case may be, exceed the
         estimate of the total cost shall be distributed in accordance with
         Section 4.2(a).

         (f) In the event the Company receives Casualty Proceeds or Eminent
Domain Proceeds, as the case may be, from an Event of Loss or an Event of
Eminent Domain that do not exceed in the aggregate $5,000,000 during any Fiscal
Year of the Company, the Company shall not have to comply with the provisions of
Sections 3.15(d) or (e) and the Casualty Proceeds or the Eminent Domain
Proceeds, as the case may be, shall be deposited in the Restoration Account in
accordance with Section 3.15(a) and applied in accordance with Section 3.15(b).



                                       29


         SECTION 3.16  Fuel Conversion Volume Rebate Account.

         (a) The Fuel Conversion Volume Rebate Account shall be funded from
funds transferred by the Collateral Agent from the Revenue Account as and when
specified in Section 3.10.

         (b) Upon receipt of an Officer's Certificate of the Company detailing
the amounts to be paid, funds in the Fuel Conversion Volume Rebate Account shall
be transferred to the Power Purchaser in accordance with Annex 1 to the Power
Purchase Agreement and as set forth in such Officer's Certificate within two (2)
Business Days of receipt of such Officer's Certificate.

         SECTION 3.17  Subordinated Debt Account.

         (a) The Subordinated Debt Account shall be funded from funds
transferred by the Collateral Agent from the Revenue Account as and when
specified in Section 3.10.

         (b) Upon receipt of an Officer's Certificate of the Company detailing
the amounts to be paid, funds in the Subordinated Debt Account shall be

         provided, that prior to any such distribution to the Trustee, the DSR
         LOC Provider or the CP LOC Provider, the Collateral Agent shall have
         received a certificate signed by an Authorized Representative of the
         Trustee, the DSR LOC Provider or the CP LOC Provider (as the case may
         be), in form and substance satisfactory to the Collateral Agent,
         setting forth the amount payable to the Trustee, the DSR LOC Provider
         or the CP LOC Provider (as the case may be) as of the date of such
         distribution;

         all Financing Liabilities owed to the

                                       30

         Providers by the Company under any Subordinated Loan Agreement;
         provided, that prior to any such distribution, the Collateral Agent

                  fourth, to the Company (or its successors or assigns) or to
         whomever may be lawfully entitled to receive the same or as a court of
         competent jurisdiction may direct, any surplus then remaining from such
         proceeds.

         (b) As used in this Section 4.1, "proceeds" of Collateral shall mean
cash, securities and other property realized in respect of, and distributions in
kind of, Collateral, including any thereof received under any reorganization,

Agent shall hold all proceeds of the Collateral received by it in connection
with such proceeding instituted by a junior lienor and not consolidated with any
action by the Collateral Agent on behalf of the Senior Parties pending
application of such proceeds by the Collateral Agent in accordance with the

         respectively, due and payable as of the date of such distribution;
         provided, that, prior to any such distribution to the Collateral Agent,
         the Trustee, the DSR LOC Provider or the CP LOC Provider, the
         Collateral Agent shall have received a certificate signed by an

                                       31



         Authorized Representative of the Trustee, the DSR LOC Provider or the
         CP LOC Provider (as the case may be), in form and substance
         satisfactory to the Collateral Agent, setting forth the amount payable
         to the Trustee, the DSR LOC Provider or the CP LOC Provider (as the

         Agent shall have received a certificate executed by an Authorized
         Representative of each such Senior Party, in form and substance
         reasonably satisfactory to the Collateral Agent, setting forth the

         equal to the unpaid amounts owed to or required to be deposited for the
         account of such Subordinated Debt Providers by the Company under any
         Subordinated Loan Agreement; provided, that prior to any such
         distribution, the Collateral Agent shall have received a certificate

         competent jurisdiction may direct, any surplus then remaining from such
         proceeds.

         (b) At the time the Collateral Agent is to make a distribution pursuant
to Section 4.2(a) paragraph second, the Collateral Agent shall deposit, with the
same priority as such distribution, ratably, into a separate trust account to be
maintained by the Collateral Agent an amount up to the maximum amount available
to be drawn under the DSR Letter of Credit (taking into account, without
duplication in the case of the DSR Letter of Credit, the maximum amount which
may become available to be drawn in the future by reason of an increase in the
DSRA Required Balance), and not represented by a DSR LOC Loan, DSR LOC Term Loan
or DSR Bond; provided, however, that if funds available are insufficient to make
all payments required under Section 4.2(a) paragraph second and the required
deposits provided for in this sentence, distribution of funds shall be made
ratably to the specified recipients. The Collateral Agent shall hold the funds
in such separate account until receipt of a written notice or notices from the
DSR LOC Provider (which such notice or notices shall be contemporaneously
delivered by the DSR LOC Provider to the other Senior Parties) executed by an
Authorized Representative of the DSR LOC Provider to the effect that either (i)
the Collateral Agent has made a drawing on the DSR Letter of Credit or (ii) the
DSR Letter of Credit has expired or terminated without a drawing being made
thereunder. Upon receipt of a notice specified in clause (i) of the preceding
sentence, the Collateral Agent shall distribute to the DSR LOC Provider that
proportionate share of the amount in the relevant separate account referred to
above, equal to such drawing's proportionate share of the DSR Letter of Credit
collateralized by such account. Upon receipt of a notice

                                       32



specified in clause (ii) of the second preceding sentence, the Collateral Agent
shall distribute from the relevant separate account (in accordance with Section
4.2(a) paragraphs second, third and fourth and without regard to this Section
4.2(b)) to the appropriate Persons an amount equal to the amount in such
separate account.

         (c) At the time the Collateral Agent is to make a distribution pursuant
to Section 4.2(a) paragraph second, the Collateral Agent shall deposit, with the
same priority as such distribution, ratably, into a separate trust account to be
maintained by the Collateral Agent an amount up to the amount available to be
drawn under the CP Letter of Credit (and not represented by a CP LOC Loan);
provided, however, that if funds available are insufficient to make all payments
required under Section 4.2(a) paragraph second and the required deposits
provided for in this sentence, distribution of funds shall be made ratably to
the specified recipients. The Collateral Agent shall hold the funds in such
separate account until receipt of a written notice or notices from the CP LOC
Provider (which such notice or notices shall be contemporaneously delivered by
the CP LOC Provider to the other Senior Parties) executed by an Authorized
Representative of the CP LOC Provider to the effect that either (i) the
Collateral Agent has made a drawing on the CP Letter of Credit or (ii) the CP
Letter of Credit has expired or terminated without a drawing being made
thereunder. Upon receipt of a notice specified in clause(i) of the preceding
sentence, the Collateral Agent shall distribute to the CP LOC Provider that
proportionate share of the amount in the relevant separate account referred to
above, equal to such drawing's proportionate share of the CP Letter of Credit
collateralized by such account. Upon receipt of a notice specified in clause(ii)
of the second preceding sentence, the Collateral Agent shall distribute from the
relevant separate account (in accordance with Section 4.2(a) paragraphs second,
third and fourth and without regard to this Section 4.2(c)) to the appropriate
Persons an amount equal to the amount in such separate account.

         (d) The Company and the Senior Parties hereby authorize the Collateral
Agent to establish the separate account described in Sections 4.2(b) and 4.2(c)
for the purposes specified in such Sections.

         (e) The DSR LOC Provider hereby covenants and agrees to use reasonable
efforts to send the written notice specified in clause (ii) of Section 4.2(b)
within three (3) Business Days following the termination or expiration of the
DSR Letter of Credit.

         (f) The CP LOC Provider hereby covenants and agrees to use reasonable
efforts to send the written notice specified in clause (ii) of Section 4.2(c)
within three (3) Business Days following the termination or expiration of the CP
Letter of Credit.

         SECTION 4.3   Application of Buy-Down Amounts.

         (a) All Buy-Down Amounts shall be deposited into a separate account
maintained by the Depositary Bank on behalf of the Collateral Agent pending
application in accordance with the remaining provisions of this Section 4.3.
Subject to the remaining provisions of this Section 4.3, the Collateral Agent
shall apply the amounts in such separate account to the payment, or
reimbursement to the extent the same have been paid or satisfied by the Company,
of the costs of modification, repair and replacement of that portion of the
Facility that requires modification,

                                       33




repair or replacement in order to remedy the circumstances giving rise to the
obligation of the Contractor to pay such Buy-Down Amounts.

         (b) The Collateral Agent is hereby authorized to disburse from such
separate account the amount required to be paid for the modification, repair or
replacement of that portion of the Facility that requires modification, repair
or replacement in order to remedy the circumstances giving rise to the
obligation of the Contractor to pay such Buy-Down Amounts as specified in
Section 4.3(a). The Collateral Agent is hereby authorized and directed to issue
its checks or transfer funds electronically for each disbursement from such
separate account, upon receipt of a Performance Enhancement Certificate signed
by an Authorized Representative of the Company and approved by the Independent
Engineer. The Collateral Agent shall be entitled to rely on all certifications
and statements in such Performance Enhancement Certificate. The Collateral Agent
shall keep and maintain adequate records pertaining to such separate account and
all disbursements therefrom and shall file an accounting thereof with the
Company and the Independent Engineer within three months following the last
business day of each Fiscal Year. Upon receipt of an Officer's Certificate of
the Company, confirmed by the Independent Engineer, certifying that all
modifications, repairs or replacements of that portion of the Facility that
requires modification, repair or replacement in order to remedy the
circumstances giving rise to the obligation of the Contractor to pay Buy-Down
Amounts have been completed, the Collateral Agent shall transfer all funds
remaining in such separate account to the Revenue Account for application in
accordance with Section 3.10(b); provided, that if such funds or a portion
thereof are deposited in the Distribution Account in accordance with Section
3.10(b) eleventh, the provisions of Section 3.14(b)(iv) and (v) shall not apply
in respect of such funds.

         (c) As soon as reasonably practicable following receipt by the Company
or the Collateral Agent of Buy-Down Amounts, the Company shall make a reasonable
good faith determination as to whether (i) it is technically feasible to modify,
repair or replace that portion of the Facility that requires modification,
repair or replacement in order to remedy the circumstances giving rise to the
obligation of the Contractor to pay such Buy-Down Amounts, (ii) the Buy-Down
Amounts, together with any other amounts that are available to the Company for
such modification, repair or replacement, are sufficient to permit such
modification, repair or replacement, including the making of all required
payments of interest and principal on the Company's Debt during such
modification, repair or replacement, (iii) the projected average Senior Debt
Service Coverage Ratio (after giving effect to such modification, repair or
replacement and the application of the Buy-Down Amounts to accomplish the same)
during the PPA Term (taken as one period) and the Post-PPA Period (taken as one
period) is equal to or greater than the projected average Senior Debt Service
Coverage Ratio set forth in the base case projections for each such period set
forth in the final offering circular dated on or before the Closing Date
relating to the Bonds and (iv) the projected minimum Senior Debt Service
Coverage Ratio (after giving effect to such modification, repair or replacement
and the application of the Buy-Down Amounts to accomplish the same) during the
PPA Term and the Post-PPA Period is equal to or greater than the projected
minimum Senior Debt Service Coverage Ratio set forth in the base case
projections for each such period set forth in the final offering circular dated
on or before the Closing Date relating to the Bonds. The determination of the
Company shall be evidenced by an Officer's Certificate (together with such
supporting detail

                                       34



as the Collateral Agent or the Independent Engineer may reasonably request)
filed with the Collateral Agent which, in the event the Company determines that
such portion of the Facility can be modified, repaired or replaced and that the
other statements set forth in clauses (ii)-(iv) of this Section 4.3(c) are true,
shall also set forth a reasonable good faith estimate by the Company of the
total cost of such modification, repair or replacement. The Company shall
deliver to the Collateral Agent at the time it delivers the Officer's
Certificate referred to above a certificate of the Independent Engineer, dated
the date of the Officer's Certificate, stating that, based upon reasonable
investigation and review of the determinations, assumptions, conclusions and
estimates of costs made by the Company, the Independent Engineer believes the
determinations, assumptions, conclusions and estimates of costs set forth in the
Officer's Certificate to be reasonable.

         (d) If the Company cannot provide the Officer's Certificate referred to
in Section 4.3(c) to permit the application of Buy-Down Amounts toward the
modification, repair or replacement of that portion of the Facility or the
Independent Engineer fails to confirm such Officer's Certificate as required by
Section 4.3(c), all of the Buy-Down Amounts received by the Company or the
Collateral Agent shall be distributed in accordance with Section 4.3(e).

         (e) All Buy-Down Amounts to be distributed pursuant to this Section
4.3(e) shall be distributed by the Collateral Agent, ratably (based on the
amount owing to the specified recipient), to (i) the Trustee in respect of the
amount of the Outstanding Bonds for redemption of Bonds in accordance with the
Indenture, (ii) the DSR LOC Provider in respect of the outstanding amount of DSR
LOC Loans, DSR LOC Term Loans or DSR LOC Bonds and (iii) the CP LOC Provider in
respect of the outstanding amount of any CP LOC Loans.

         (f) At the time the Collateral Agent is to make a distribution pursuant
to Section 4.3(e), the Collateral Agent shall deposit into a separate trust
account to be maintained by the Collateral Agent an amount up to the amount
available to be drawn under the DSR Letter of Credit (taking into account,
without duplication, in the case of the DSR Letter of Credit, the maximum amount
which may become available to be drawn in the future by reason of an increase in
the DSRA Required Balance), and not represented by a DSR LOC Loan, DSR LOC Term
Loan or DSR Bond; provided, however, that if funds available are insufficient to
make all payments required under Section 4.2(a) paragraph second and the
required deposits provided for in this sentence, distribution of funds shall be
made ratably to the specified recipients. The Collateral Agent shall hold the
funds in such separate account until receipt of a written notice or notices from
the DSR LOC Provider (which such notice or notices shall be contemporaneously
delivered by the DSR LOC Provider to the other Senior Parties) executed by an
Authorized Representative of the DSR LOC Provider to the effect that either (i)
the Collateral Agent has made a drawing on the DSR Letter of Credit or (ii) the
DSR Letter of Credit has expired or terminated without a drawing being made
thereunder. Upon receipt of a notice specified in clause (i) above, the
Collateral Agent shall distribute to the DSR LOC Provider that proportionate
share of the amount in the relevant separate account referred to above, equal to
such drawing's proportionate share of the DSR Letter of Credit collateralized by
such account. Upon receipt of a notice specified in clause (ii) above, the
Collateral Agent shall distribute from

                                       35





the relevant separate account to the Trustee an amount equal to the amount in
such separate account.

         (g) At the time the Collateral Agent is to make a distribution pursuant
to Section 4.3(e), the Collateral Agent shall deposit into a separate trust
account to be maintained by the Collateral Agent an amount available to be drawn
under the CP Letter of Credit (and not represented by a CP LOC Loan); provided,
however, that if funds available are insufficient to make all payments required
under Section 4.2(a) paragraph second and the required deposits provided for in
this sentence, distribution of funds shall be made ratably to the specified
recipients. The Collateral Agent shall hold the funds in such separate account
until receipt of a written notice or notices from the CP LOC Provider (which
such notice or notices shall be contemporaneously delivered by the CP LOC
Provider to the other Senior Parties) executed by an Authorized Representative
of the CP LOC Provider to the effect that either (i) the Collateral Agent has
made a drawing on the CP Letter of Credit or (ii) the CP Letter of Credit has
expired or terminated without a drawing being made thereunder. Upon receipt of a
notice specified in clause (i) above, the Collateral Agent shall distribute to
the CP LOC Provider that proportionate share of the amount in the relevant
separate account referred to above, equal to such drawing's proportionate share
of the CP Letter of Credit collateralized by such account. Upon receipt of a
notice specified in clause (ii) above, the Collateral Agent shall distribute
from the relevant separate account to the Trustee an amount equal to the amount
in such separate account.

                                   ARTICLE V

                        COLLATERAL AGENT; DEPOSITARY BANK

         SECTION 5.1   Appointment and Duties of Collateral Agent and Depositary
                       Bank.

         (a) The Senior Parties hereby designate and appoint IBJ Whitehall Bank
& Trust Company to act as the Collateral Agent under the Security Documents and
this Agreement, and each of the Senior Parties hereby authorizes IBJ Whitehall
Bank & Trust Company, as the Collateral Agent, to take such actions on its
behalf under the provisions of the Security Documents and this Agreement and to
exercise such powers and perform such duties as are expressly delegated to the
Collateral Agent by the terms of the Security Documents and this Agreement,
together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in the Security
Documents and this Agreement, the Collateral Agent shall not have any duties or
responsibilities, except those expressly set forth in the Security Documents and
this Agreement, or any discretionary or fiduciary duties or responsibilities
with any Senior Party under this Agreement or any other Security Documents, and
no implied covenants, functions or responsibilities shall be read into the
Security Documents, this Agreement or otherwise exist against the Collateral
Agent. The Collateral Agent shall not be liable for any action taken or omitted
to be taken by it hereunder or under any Security Document, or in connection
herewith or therewith, or in connection with the Collateral, unless caused by
its gross negligence or willful misconduct.

                                       36



         (b) The Collateral Agent and each other Senior Party hereby designate
and appoint IBJ Whitehall Bank & Trust Company to act as the Depositary Bank
under this Agreement, and the Depositary Bank hereby agrees to act as
"securities intermediary" (within the meaning of Section 8-102(a)(14) of the
UCC) with respect to the Project Accounts. The Company hereby acknowledges that
the Depositary Bank shall act as securities intermediary with respect to the
Project Accounts and pursuant to this Agreement. The Depositary Bank shall not
have any duties or responsibilities except those expressly set forth in this
Agreement.

         (c) The Collateral Agent will give notice to the Senior Parties of any
action taken, or notices received, hereunder or under any Security Document;
notice of action taken shall be given prior to the taking of such action unless
the Collateral Agent determines that to do so would be detrimental to the
interest of the Senior Parties, in which event such notice shall be given
promptly after the taking of such action.

         (d) The Senior Parties agree that all liens and security interests in
the Collateral securing the Secured Obligations shall be held in the name of the
Collateral Agent and administered by and through the Collateral Agent and in
accordance with this Agreement and the other Security Documents. If, as of the
date hereof, or at any time in the future, any Senior Party at any time holds a
lien or security interest on any Collateral in its own name, it agrees to assign
it, without warranty or recourse, to the Collateral Agent (to be held by the
Collateral Agent as the collateral agent for the Senior Parties). The Collateral
Agent shall hold its security interests in and liens on the Collateral for the
benefit of the Senior Parties as provided herein and in the Security Documents.

         (e) Notwithstanding anything to the contrary in this Agreement or any
Security Document, the Collateral Agent shall not be required to exercise any
rights or remedies under any of the Security Documents or this Agreement or give
any consent under any of the Security Documents or this Agreement or enter into
any agreement amending, modifying, supplementing or waiving any provision of any
Security Document unless it shall have been directed to do so in Senior Party
Certificates of the Required Senior Parties.

         SECTION 5.2   Rights of Collateral Agent.

         (a) The Collateral Agent may execute any of its duties under the
Security Documents or this Agreement by or through agents or attorneys-in-fact
and shall be entitled to advice of counsel concerning all matters pertaining to
such duties.

         (b) Neither the Collateral Agent nor any of its officers, directors,
employees, agents, attorneys-in-fact or affiliates shall be (i) liable for any
action lawfully taken or omitted to be taken by it under or in connection with
any Security Document or this Agreement (except for its gross negligence or
willful misconduct) or (ii) responsible in any manner to any of the Senior
Parties for any recitals, statements, representations or warranties made in any
Security Document or this Agreement or in any certificate, report, statement or
other document referred to or provided for in, or received by the Collateral
Agent under or in connection with, any Security Document or this Agreement or
for the value, validity, effectiveness, genuineness, enforceability or
sufficiency of the Security Documents or this Agreement or for any failure of
the Company or

                                       37



any other Person to perform their obligations thereunder. The Collateral Agent
shall not be under any obligation to any Senior Party or any other Person to
ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, any Security Document or this
Agreement, or to inspect the properties, books or records of the Company.

         (c) The Collateral Agent shall be entitled to rely, and shall be fully
protected in relying, upon any note, writing, resolution, request, direction,
certificate, notice, consent, affidavit, letter, cablegram, telegram, telecopy,
telex or teletype message, statement, order or other document or conversation
believed by it to be genuine and correct and to have been signed, sent or made
by the proper Person or Persons and/or upon advice and/or statements of legal
counsel (including, without limitation, counsel to the Company), independent
accountants and other experts selected by the Collateral Agent. In connection
with any request or direction of the Required Senior Parties, the Collateral
Agent shall be entitled to rely, and shall be fully protected in relying on any
Senior Party Certificate delivered by a Senior Party; provided, however, that in
the event the Collateral Agent receives conflicting directions contained in
Senior Party Certificates representing two or more groups of Required Senior
Parties, the Collateral Agent shall act in accordance with directions contained
in Senior Party Certificates representing the greatest percentage of the
Combined Exposure. The Collateral Agent shall be fully justified in failing or
refusing to take any action under any Security Document or this Agreement (i) if
such action would, in the opinion of the Collateral Agent (which may be based on
the opinion of legal counsel), be contrary to law or the terms of this Agreement
or the other Security Documents, (ii) if such action is not specifically
provided for in such Security Document or this Agreement or it shall not have
received any such advice or concurrence of the Required Senior Parties as it
deems appropriate, (iii) if, in connection with the taking of any such action
hereunder or under any Security Document that would constitute an exercise of
remedies under such Security Document or this Agreement, it shall not first be
indemnified to its satisfaction by the Senior Parties (other than the Trustee in
its individual capacity and the Collateral Agent) against any and all risk of
nonpayment, liability and expense which may be incurred by it by reason of
taking or continuing to take any such action or (iv) if, notwithstanding
anything to the contrary contained in Section 5.2(e), in connection with the
taking of any such action that would constitute a payment due under any
Transaction Document, it shall not first have received from the Senior Parties
funds equal to the amount payable. The Collateral Agent shall in all cases be
fully protected in acting, or in refraining from acting, under any Security
Document or this Agreement in accordance with a request of the Required Senior
Parties contained in Senior Party Certificates, and such request and any action
taken or failure to act pursuant thereto shall be binding upon all the Senior
Parties.

         (d) If, with respect to a proposed action to be taken by it, the
Collateral Agent shall determine in good faith that the provisions of any
Security Document or this Agreement relating to the functions or
responsibilities or discretionary powers of the Collateral Agent are or may be
ambiguous or inconsistent, the Collateral Agent shall notify the Senior Parties,
identifying the proposed action, and may decline either to perform such function
or responsibility or to take the action requested unless it has received the
written confirmation of the Required Senior Parties executed by Authorized
Representatives of such Persons that the Required Senior Parties concur in the
circumstances that the action proposed to be taken by the Collateral Agent is
consistent

                                       38



with the terms of this Agreement or such Security Document or is otherwise
appropriate. The Collateral Agent shall be fully protected in acting or
refraining from acting upon the confirmation of the Required Senior Parties in
this respect, and such confirmation shall be binding upon the Collateral Agent
and the other Senior Parties.

         (e) The Collateral Agent shall not be deemed to have actual,
constructive, direct or indirect knowledge or notice of the occurrence of any
default or Event of Default or any other event unless and until a Responsible
Officer of the Collateral Agent has received a written notice or a certificate
from an Authorized Representative of a Senior Party or the Company stating that
a default or an Event of Default has occurred. The Collateral Agent shall have
no obligation whatsoever either prior to or after receiving such notice or
certificate to inquire whether a default or an Event of Default has in fact
occurred and shall be entitled to rely conclusively, and shall be fully
protected in so relying, on any notice or certificate so furnished to it. No
provision of this Agreement or any other Security Document shall require the
Collateral Agent to expend or risk its own funds or otherwise incur any
financial liability in the performance of any of its duties hereunder or under
any Security Document or the exercise of any of its rights or powers, if it
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability including an advance of funds
necessary to take the action requested is not reasonably assured to it, except
that in respect of any potential environmental liability or the taking of title
to any real property, the Collateral Agent may decline to act unless it receives
indemnity satisfactory to it in its sole discretion, including, but not limited
to, an advance of funds necessary to take the action requested. If the
Collateral Agent receives such a notice of the occurrence of any Event of
Default, the Collateral Agent shall give notice thereof to the Senior Parties.
The Senior Parties shall provide evidence of satisfactory indemnity to the
Collateral Agent for any action directed by the Required Senior Parties
including, but not limited to, an advance of funds necessary to take the action
requested. The Collateral Agent shall take such action with respect to such
Event of Default as so requested pursuant to Section 2.3(a) subject, however, to
the third sentence of this Section 5.2(e).

         (f) The Company will pay upon demand to the Collateral Agent the amount
of any and all reasonable fees and out-of-pocket expenses, including the
reasonable fees and expenses of its counsel (and any one local counsel) and of
any experts and agents, which the Collateral Agent may incur in connection with
(i) the administration of this Agreement and the other Security Documents, (ii)
the custody or preservation of, or the sale of, collection from, or other
realization upon, any of the Collateral, (iii) the exercise or enforcement
(whether through negotiations, legal proceedings or otherwise) of any of the
rights of the Collateral Agent or the Senior Parties hereunder or under the
other Security Documents or (iv) the failure by the Company to perform or
observe any of the provisions hereof or of any of the other Security Documents.
The provision of this Section 5.2(f) shall survive the expiration or earlier
termination of this Agreement.

         SECTION 5.3   Lack of Reliance on the Collateral Agent.

         Each of the Senior Parties expressly acknowledges that neither the
Collateral Agent nor any of its officers, directors, employees, agents or
attorneys-in-fact has made any representations

                                       39



or warranties to it and that no act by the Collateral Agent hereafter taken,
including, without limitation, any review of the Facility or of the affairs of
the Company, shall be deemed to constitute any representation or warranty by the
Collateral Agent to any Senior Party. Each Senior Party (other than the Trustee)
represents to the Collateral Agent that it has, independently and without
reliance upon the Collateral Agent or any other Senior Party, and based on such
documents and information as it has deemed appropriate, made its own appraisal
of and investigation into the business, operations, property, financial and
other condition and creditworthiness of the Facility and the Company. Each
Senior Party (other than the Trustee) also represents that it will,
independently and without reliance upon the Collateral Agent or any other Senior
Party, and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit analysis, appraisals and decisions
in taking or not taking action under this Agreement, and to make such
investigation as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of the
Facility and the Company. Except for notices, reports and other documents
expressly required to be furnished to the Senior Parties by the Collateral Agent
hereunder, the Collateral Agent shall not have any duty or responsibility to
provide any Senior Party with any credit or other information concerning the
business, operations, property, financial and other condition or
creditworthiness of the Facility and the Company which may come into the
possession of the Collateral Agent or any of its officers, directors, employees,
agents or attorneys-in-fact.

         SECTION 5.4   Indemnification.

         (a) The Senior Parties (other than the Collateral Agent) severally
agree to indemnify the Collateral Agent in its capacity as such and in its
individual capacity (to the extent not reimbursed by the Company and without
limiting the obligation of the Company to do so), ratably according to the
aggregate amounts of their respective Secured Obligations on the date the
activities giving rise to the Collateral Agent's demand for indemnification
occurred, from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind whatsoever which may at any time be imposed on, incurred by or
asserted against the Collateral Agent in its capacity as such and in its
individual capacity in any way relating to or arising out of the Security
Documents or this Agreement, or the performance of its duties as Collateral
Agent hereunder or thereunder or any action taken or omitted by the Collateral
Agent in its capacity as such under or in connection with any of the foregoing
(including, but not limited to, any claim that the Collateral Agent is the owner
or operator of the Facility and liable as such pursuant to the Comprehensive
Environmental Response, Compensation and Liability Act or any other
Environmental Requirement); provided, that the Senior Parties shall not be
liable for the payment of any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
to the extent that any of the foregoing result from the Collateral Agent's gross
negligence or willful misconduct. The agreements in this Section 5.4 shall
survive the payment or satisfaction in full of the Secured Obligations or any
other termination of this Agreement.

         (b) The Company agrees to indemnify the Collateral Agent and each
Senior Party from and against any and all claims, losses and liabilities growing
out of or resulting from (i) any

                                       40


Security Document or this Agreement (including, without limitation, enforcement
of such Security Document, but excluding any such claims, losses or liabilities
resulting from the Collateral Agent's or such Senior Party's gross negligence or
willful misconduct) or (ii) any refund or adjustment of any amount paid or
payable to the Collateral Agent or any Senior Party under or in respect of any
Transaction Document or any other Collateral, or any interest thereon, which may
be ordered or otherwise required by any Person. The agreements under this
Section 5.4(b) shall survive the payment in full of any secured obligation or
termination of this Agreement or any other Security Document.

         SECTION 5.5   Resignation of the Collateral Agent or Depositary Bank.

         (a) Either of the Collateral Agent or Depositary Bank may resign its
appointment hereunder at any time without providing any reason therefor by
giving not less than 60 days' prior written notice to that effect to each of the
other parties hereto, provided that no such resignation pursuant to this Section
5.5 or removal pursuant to Section 5.6 shall be effective until:

                  (i) a successor for the Collateral Agent or Depositary Bank is
         appointed in accordance with (and subject to) the succeeding provisions
         of this Section 5.5;

                  (ii) the resigning or removed Collateral Agent or Depositary
         Bank has transferred to its successor all of its rights and obligations
         in its capacity as Collateral Agent or Depositary Bank under this
         Agreement and the other Transaction Documents; and

                  (iii) the successor Collateral Agent or Depositary Bank has
         executed and delivered an agreement to be bound by the terms hereof and
         the other Transaction Documents and perform all duties required of the
         Collateral Agent or Depositary Bank hereunder and under the other
         Transaction Documents.

         (b) If the Collateral Agent or Depositary Bank has given notice of its
resignation pursuant to this Section 5.5 or if the Required Senior Parties give
the Collateral Agent, or the Collateral Agent gives the Depositary Bank, notice
of removal pursuant to Section 5.6, then a successor to the Collateral Agent or
Depositary Bank may be appointed by the Required Senior Parties during the
period of such notice but, if no such successor is so appointed within sixty
(60) days after the above notice, the Collateral Agent or Depositary Bank may
appoint such a successor which (i) is authorized under the laws of its
jurisdiction of formation to exercise corporation trust powers, (ii) shall have
a combined capital and surplus of at least U.S.$250,000,000 and (iii) shall be
acceptable to the Required Senior Parties (provided, that if the Required Senior
Parties do not confirm such acceptance or reject such appointee in writing
within thirty (30) days following selection of such successor by the Collateral
Agent or Depositary Bank, then they shall be deemed to have given acceptance
thereof and such successor shall be deemed appointed as the Collateral Agent or
Depositary Bank hereunder by and on behalf of the Senior Parties).

                                       41



         (c) If a successor to the Collateral Agent or Depositary Bank is
appointed under the provisions of clauses (a) or (b) above, then:

                  (i) the predecessor Collateral Agent or Depositary Bank shall
         be discharged from any further obligation hereunder (but without
         prejudice to any accrued liabilities);

                  (ii) the predecessor Collateral Agent or Depositary Bank's
         resignation pursuant to this Section 5.5 or removal pursuant to Section
         5.6 notwithstanding, the provisions of this Agreement shall inure to
         its benefit as to any actions taken or omitted to be taken by it under
         this Agreement and the other Transaction Documents while it was acting
         as the Collateral Agent or Depositary Bank; and

                  (iii) the successor Collateral Agent or Depositary Bank and
         each of the other parties hereto shall have the same rights and
         obligations amongst themselves as they would have had if such successor
         Collateral Agent or Depositary Bank had been an original party hereto.

         SECTION 5.6   Removal of the Collateral Agent or Depositary Bank.

         The Required Senior Parties may remove the Collateral Agent from its
appointment hereunder, and the Collateral Agent may remove the Depositary Bank
hereunder, in each case with or without cause by giving not less than 60 days'
prior written notice to that effect to the Collateral Agent (or to the
Depositary Bank, as the case may be); provided, that no such removal shall be
effective until a successor for the Collateral Agent (or the Depositary Bank, as
the case may be) is appointed in accordance with Section 5.5.

         SECTION 5.7   Merger, Conversion, Consolidation or Succession to
                       Business.

         Any corporation or bank into which the Collateral Agent may be merged
or converted or with which it may be consolidated, or any corporation or bank
resulting from any merger, conversion or consolidation to which the Collateral
Agent shall be a party, or any corporation or bank succeeding to all or
substantially all of the corporate trust business of the Collateral Agent, shall
be the successor of the Collateral Agent hereunder, provided such corporation or
bank shall be otherwise qualified and eligible under this Article V, without the
execution or filing of any paper or any further act on the part of any of the
parties hereto.

         SECTION 5.8   Power of Attorney.

         Each Senior Party (other than the Collateral Agent) hereby gives a
power of attorney, coupled with an interest, to the Collateral Agent and
appoints, makes, constitutes and designates the Collateral Agent its true and
lawful attorney-in-fact, subject to Section 5.1, to consent on its behalf under
the Security Documents and the other Transaction Documents to which the
Collateral Agent is a party to the extent that the consent of the Required
Senior Parties (whether or not acting through the Collateral Agent) is required
under any agreement and upon the instructions of the Required Senior Parties
acting pursuant to this Agreement, and to take such actions on its behalf under
the provisions of such agreements as are reasonably incidental thereto,

                                       42



to execute and deliver in the name of and on behalf of, or in its own name, as

         to do business in the Commonwealth of Pennsylvania and in each other
         jurisdiction where the character of its properties or the nature of its
         activities makes such qualification necessary, except to the extent any
         failure could not reasonably be expected to have a Material Adverse
         Effect. The Company has all requisite power and authority to own and
         operate the property it purports to own and to carry on its business as
         now being conducted and as proposed to be conducted in respect of the

         Agreement nor the consummation of any of the transactions contemplated
         hereby nor performance of or compliance with the terms and conditions

         of any Liens (other than Permitted Liens) on any of the Collateral
         under, or results in the acceleration of, any obligation.

                  (v) Other than as set forth in the Indenture, there are no
         actions, suits or proceedings at law or in equity or by or before any
         Governmental Authority now pending against the Company or, to the best
         of the Company's knowledge, threatened against the Company or any
         property or other assets or rights of the Company or with respect to
         this Agreement that would reasonably be expected to have a Material
         Adverse Effect.

         hereinafter defined) to which it is a party.

                  (ii) It has all necessary corporate power to execute, deliver

         or which questions the validity, binding effect or enforceability
         hereof or of the Senior Documents, any action to be taken pursuant

                                       48



Act) or (ii) any Affiliate of the Company or any incorporators, officers,
directors or employees thereof, and no judgment for any deficiency upon the
obligations of the Company under this Agreement or any other Financing Document,
for the payment of the principal of or premium, if any, or interest on any
Financing Liability, or any part thereof, or for any claim based thereon or

         SECTION 7.14  Replacement and/or Removal of Independent Engineer;
                       Payment of Independent Engineer.

         The Company shall in accordance with Section 1 of the Independent
Engineer Agreement, have the right to replace the then current Independent
Engineer at the expiration of the then current term of the Independent Engineer
Agreement and shall appoint a successor Independent Engineer from the engineers
listed on Exhibit 7.14. The Collateral Agent shall, upon receipt of a written
request contained in Senior Party Certificates of the Required Senior Parties,
remove the Independent Engineer if at any time the Independent Engineer becomes
incapable of acting or is, or is reasonably likely to be, adjudged bankrupt or
insolvent or a receiver is appointed for, or any public officer shall take
charge or control of, the Independent Engineer or its property or its affairs
for the purpose of rehabilitation, conservation or liquidation, and shall
appoint a successor Independent Engineer from those engineers then listed on
Exhibit 7.14. Within thirty (30) days of receipt by the Collateral Agent of a
written notification from the Company to the effect that the Independent
Engineer has failed to carry out its obligations in a timely manner, the
Collateral Agent shall, unless directed in Senior Party Certificates of the
Required Senior Parties not to do so, remove the Independent Engineer and
appoint a successor Independent Engineer from those engineers then listed on
Exhibit 7.14. The Company shall pay for all services performed by the
Independent Engineer and its reasonable costs and expenses related thereto.

         SECTION 7.15  Third-Party Engineer Dispute Resolution.

         (a) If the Company and the Independent Engineer are in dispute in
respect of a notice, plan, report, certificate or budget and they are unable to
resolve the dispute within seven (7) days of the Independent Engineer expressing
its disagreement with such notice, plan, report, certificate or budget, a single
independent engineer (the "Third-Party Engineer") shall be designated to
consider and decide the issues raised by such dispute. The selection of such
Third-Party Engineer shall be made from the list of engineers described below,
the initial version of which is attached as Exhibit 7.14. The Company, as the
case may be, shall designate the Third-Party Engineer from such list not later
than the third (3rd) day following the expiration of the seven (7)

                                       49



day period described above and such designation shall become effective in three
(3) days. Within three (3) days of the designation of a Third-Party Engineer,
each of the Company and the Independent Engineer shall submit to the Third-Party
Engineer a notice setting forth in detail such Person's position in respect of
the issues in dispute. Such notice shall include supporting documentation, if
appropriate.

         (b) The Third-Party Engineer shall complete all proceedings and issue
his decision with regard to the issues in dispute as promptly as reasonably
possible, but in any event within ten (10) days of the date on which he is
designated as the Third-Party Engineer unless the Third-Party Engineer
reasonably determines that additional time is required in order to give adequate
consideration to the issues raised. In such case the Third-Party Engineer shall
state in writing his reasons for believing that additional time is needed and
shall specify the additional period required, which such period shall not exceed
ten (10) days without the Company's agreement.

         (c) If the Third-Party Engineer determines that the position set forth
in the Independent Engineer's notice is correct, it shall so state and shall
state the corrective actions to be taken by the Company. In such case, the
Company shall promptly take such actions. The Company shall thereafter bear all
costs which may arise from actions taken pursuant to the Third-Party Engineer's
decision. If the Third-Party Engineer determines that the position set forth in
the Independent Engineer's notice is not correct, it shall so state and shall
state the appropriate actions to be taken by the Company. In such case, the
Company shall take such actions and for purposes of the Financing Documents, the
Independent Engineer and the Collateral Agent shall be deemed to have approved,
confirmed, concurred in or consented to the notice, plan, report, certificate or
budget in dispute. The decision of the Third-Party Engineer shall be final and
non-appealable. The Company shall bear all reasonable costs incurred by the
Third-Party Engineer in connection with this dispute resolution mechanism.

         (d) The Third-Party Engineer shall be chosen from the list of qualified
engineers set forth in Exhibit 7.14. Such list shall be used by the Collateral
Agent (upon written direction of the Required Senior Parties) to choose a
successor Independent Engineer as well. At any time either the Company or the
Collateral Agent (upon written direction of the Required Senior Parties) may
remove a particular engineer from the list by obtaining the other Person's
reasonable consent to such removal. However, neither the Company nor the
Collateral Agent may remove a name or names from the list if such removal would
leave the list without at least two (2) names, unless, concurrently therewith,
the Company and the Collateral Agent (upon direction of the Required Senior
Parties) reasonably agree to the addition of one (1) or more names to such list.

         (e) During January of each year, each of the Company and the Collateral
Agent (upon direction of the Required Senior Parties) shall review the current
list of Third-Party Engineers and give notice to the other of any proposed
additions to the list and any intended deletions. Intended deletions shall
automatically become effective forty-five (45) days after notice is received by
the other Person unless written objection is made by such other Person within
thirty (30) days and provided that such deletions do not leave the list without
at least two (2) names. Proposed additions to the list shall automatically
become effective thirty forty-five (45) after

                                   EXHIBIT 2.2

                             TERMS OF SUBORDINATION


         Reference is made herein to a certain Collateral Agency and
Intercreditor Agreement, dated as of June 1, 1999 (as amended and in effect from
time to time, the "Collateral Agency Agreement"), entered into among IBJ
Whitehall Bank & Trust Company, as Collateral Agent (in such capacity, together
with its successors and permitted assigns in such capacity, the "Collateral
Agent"), IBJ Whitehall Bank & Trust Company, (in such capacity, together with
its successors and permitted assigns in such capacity, the "Depositary Bank "),
IBJ Whitehall Bank & Trust Company, as Trustee under the Indenture named
therein, on its own behalf and on behalf of the Bondholders described therein
(in such capacity, together with its successors and permitted assigns in such
capacity, the "Trustee"), the other Senior Parties identified therein, the
Subordinated Debt Providers referred to therein, and AES Ironwood, L.L.C. (the
"Company"). Capitalized terms used but not defined herein shall have the
respective meanings ascribed thereto in the Collateral Agency Agreement, the
terms of which are incorporated herein.

         (i) Subordination of Subordinated Obligations. The Company, for itself
and its successors and assigns, covenants and agrees, and each Subordinated Debt
Provider that has entered into these Terms of Subordination set forth in this
annex or appendix (the "Terms of Subordination"), who then through the
incorporation of these terms into an executed agreement or otherwise, on its own
behalf and on behalf of each subsequent holder of the Subordinated Obligations
(defined below), likewise covenants and agrees, that, to the extent and in the
manner set forth in these Terms of Subordination, the Subordinated Debt, whether
of principal of and interest and premium (including any Make-Whole Premium) or
prepayment or liquidation penalty (if any) on the Subordinated Debt and fees and
expenses incurred in enforcement of the same (collectively, the "Subordinated
Obligations"), are hereby expressly made subordinate and subject in right of
payment to the prior payment in full in cash of all obligations in respect of
Senior Debt, whether of principal, interest or premium (including any Make-Whole
Premium), if any, and fees and expenses incurred in the enforcement of the same
and the fees, expenses and indemnities to be paid to the Collateral Agent and
the Depositary Bank pursuant to the Collateral Agency Agreement (collectively,
the "Senior Obligations"); provided, however, that nothing in these Terms of
Subordination shall be deemed to prohibit any Subordinated Debt Provider from
receiving payments in accordance with the terms of the Collateral Agency
Agreement, including but not limited to Section 3.10 and Article IV thereof.

         (ii) Payment of Proceeds Upon Dissolution. In the event of (i) any
insolvency or bankruptcy case or proceeding, or any receivership, liquidation,
reorganization or other similar case or proceeding in connection therewith,
relative to the Company or to its creditors, as such, or to its assets, or (ii)
any liquidation, dissolution or other winding up of the Company, whether
voluntary or involuntary and whether or not involving insolvency or bankruptcy,
or (iii) any assignment for the benefit of creditors or any other marshalling of
assets and liabilities of the Company, then and in any such event:

                                    2.2 - 1



                  (A) the Senior Parties shall be entitled to receive payment in
         full in cash of all amounts due or to become due on or in respect of
         all Senior Obligations, or provision shall be made for such payment,
         before any Subordinated Debt Provider shall be entitled to receive any
         payment of the Subordinated Obligations;

                  (B) any payment or distribution of assets of the Company of
         any kind or character, whether in cash, property or securities, by
         set-off or otherwise, to which any Subordinated Party would be entitled
         but for the provisions of these Terms of Subordination, including any
         such payment or distribution that may be payable or deliverable by
         reason of the payment of any other indebtedness of the Company being
         subordinated to the payment of the Subordinated Obligations, shall be
         paid by the liquidating trustee or agent or other Person making such
         payment or distribution, whether a trustee in bankruptcy, a receiver or
         liquidating trustee or otherwise, to the Collateral Agent for
         distribution in accordance with the terms of the Collateral Agency
         Agreement.

                  (C) if, notwithstanding the foregoing provisions of this
         clause (ii) of these Terms of Subordination, any Subordinated Debt
         Provider shall have received, before all Senior Obligations are paid in
         full in cash or payment thereof provided for, any such payment or
         distribution of assets of the Company of any kind or character, whether
         in cash, property or securities, including any such payment or
         distribution arising out of the exercise by any Subordinated Debt
         Provider of a right of set-off or counterclaim and any such payment or
         distribution received by reason of any other indebtedness of the
         Company being subordinated to the Subordinated Obligations, then, and
         in such event, such payment or distribution shall be held in trust for
         the benefit of, and shall be immediately paid over or delivered to, the
         Collateral Agent for distribution in accordance with the terms of the
         Collateral Agency Agreement; and

                  (D) if any Subordinated Debt Provider shall have failed to
         file claims or proofs of claim with respect to the Subordinated
         Obligations earlier than [15] days prior to the deadline for any such
         filing, the Subordinated Debt Provider shall execute and deliver to the
         Senior Parties such powers of attorney, assignments or other
         instruments as the Required Senior Parties may reasonably request to
         file such claims or proofs of claim.

         The consolidation of the Company with, or the merger of the Company
into, another entity or the liquidation or dissolution of the Company following
the conveyance or transfer of its properties and assets substantially as an
entirety to another entity upon the terms and conditions set forth in the
Indenture or the correlative provisions of any other Financing Document shall
not be deemed a dissolution, winding up, liquidation, reorganization, assignment
for the benefit of creditors or marshalling of assets and liabilities of the
Company for purposes of these Terms of Subordination if the entity formed by
such consolidation or into which the Company is merged or the entity that
acquires by conveyance or transfer such properties and assets substantially as
an entirety, as the case may be, shall, as a part of such consolidation, merger,
conveyance or transfer, comply with the conditions set forth in the Indenture or
such correlative provisions of any other Financing Document.

                                    2.2 - 2



         (iii) No Payment. Each Subordinated Debt Provider hereby agrees that,
unless and until the Senior Obligations shall have been paid in full in cash,
(i) no payment on account of the Subordinated Obligations or any judgment with
respect thereto (and no payment on account of the purchase or redemption or
other acquisition of the Subordinated Obligations) shall be made by the Company
or by the Collateral Agent or the Depositary Bank on behalf of the Company and
(ii) no Subordinated Debt Provider shall (A) ask, demand, sue for, take or
receive from the Company, by set-off or in any other manner, or (B) seek any
other remedy allowed at law or in equity against the Company for breach of the
Company's obligations under the instruments representing such Subordinated
Obligations, provided that nothing herein shall be deemed to prohibit payment of
any of the Subordinated Obligations on any day that, under the terms thereof, is
a scheduled payment date to the extent expressly permitted by Section 3.10 of
the Collateral Agency Agreement and the correlative provisions of any other
Financing Document and solely to the extent of available funds.

         In the event that, notwithstanding the foregoing provisions of this
clause (iii) of these Terms of Subordination, any Subordinated Debt Provider
shall have received any payment prohibited by the foregoing provisions of this
clause (iii) including, without limitation, any such payment arising out of the
exercise by any Subordinated Debt Provider of a right of set-off or counterclaim
and any such payment received by reason of other indebtedness of the Company
being subordinated to the Subordinated Obligations, then, and in any such event,
such payment shall be held in trust for the benefit of, and shall be immediately
paid over or delivered to, the Collateral Agent for application in accordance
with the Collateral Agency Agreement.

         The provisions of this clause (iii) of these Terms of Subordination
shall not alter the rights of the Senior Parties under the provisions of clause
(ii) of these Terms of Subordination.

         (iv) Subrogation. Subject to the payment in full in cash of all Senior
Obligations, the Subordinated Debt Providers shall be subrogated (equally and
ratably with the holders of all indebtedness of the Company that by its express
terms is subordinated to Senior Obligations of the Company to the same extent as
the Subordinated Obligations are subordinated and that is entitled to like
rights of subrogation) to the rights of the Senior Parties to receive payments
and distributions of cash, property and securities applicable to the Senior
Obligations until the Subordinated Obligations shall be paid in full in cash.
For purposes of such subrogation, no payments or distributions to the Senior
Parties of any such, property or securities to which any Subordinated Debt
Provider would be entitled except for the provisions of these Terms of
Subordination, and no payments over pursuant to the provisions of these Terms of
Subordination to the Senior Parties by any Subordinated Debt Providers, shall be
deemed to be a payment or distribution by the Company to or on account of the
Senior Obligations.

         (v) Provisions Solely to Define Relative Rights. The provisions of
these Terms of Subordination are and are intended solely for the purpose of
defining the relative rights of the Subordinated Debt Providers on the one hand
and the Senior Parties and the Collateral Agent on the other hand. Nothing
contained in these Terms of Subordination or elsewhere in any of the Financing
Documents relating to the Subordinated Obligations is intended to or shall:

                                    2.2 - 3



                  (A) affect, as among the Company, its creditors other than the
         Senior Parties and the Subordinated Debt Providers, the obligation of
         the Company to pay to the Subordinated Debt Providers, the Subordinated
         Obligations as and when the same shall become due and payable in
         accordance with their terms;

                  (B) affect the relative rights against the Company of the
         Subordinated Debt Providers and creditors of the Company other than the
         Senior Parties;

                  (C) vitiate the occurrence of an "Event of Default" under the
         Indenture or the correlative provisions of any other Financing Document
         to the extent that any failure to make a payment of principal of, or
         interest on, any Subordinated Obligations by reason of the conditions
         specified in clause (ii) or (iii) of these Terms of Subordination would
         otherwise constitute such an Event of Default; or

                  (D) prevent any Subordinated Debt Provider from exercising all
         remedies otherwise permitted by Applicable Law upon default under any
         of the Financing Documents relating to the Subordinated Obligations,
         subject to the rights, if any, under these Terms of Subordination of
         the Senior Parties, (i) in the event of any proceeding, dissolution,
         liquidation or other winding up, assignment for the benefit of
         creditors or other marshalling of assets and liabilities of the Company
         referred to in clause (ii) of these Terms of Subordination, to receive,
         pursuant to and in accordance with such clause (ii), cash, property and
         securities otherwise payable or deliverable to the Subordinated Debt
         Providers, or (ii) under the conditions specified in clause (iii) of
         these Terms of Subordination, to prevent any payment or action
         prohibited by such clause (iii).

         (vi) No Waiver of Subordination Provisions. No right of any present or
future Senior Party or the Collateral Agent to enforce subordination as herein
provided shall at any time in any way be prejudiced or impaired by any act or
failure to act on the part of the Company or by any act or failure to act, in
good faith, by such Senior Party, or by any non-compliance by the Company with
the terms, provisions and covenants of these Terms of Subordination, regardless
of any knowledge thereof such Senior Party may have or be otherwise charged
with.

         Without in any way limiting the generality of the foregoing paragraph,
the occurrence of any one or more of the following (without the consent of or
notice to any Subordinated Debt Provider), shall not cause any Senior Party to
incur any responsibility to any Subordinated Debt Provider or the obligations
hereunder of any Subordinated Debt Provider to the Senior Parties:

                  (A) at any time or from time to time, the time for any
         performance of or compliance with any Subordinated Obligation or any
         Senior Obligation shall be extended, or such performance or compliance
         shall be waived;

                  (B) any of the acts mentioned in any of the provisions of any
         of the Collateral Agency Agreement, the Indenture, any other
         Transaction Document, any other Financing Document or any other
         agreement or instrument referred to herein or therein shall be done or
         omitted;

                                    2.2 - 4



                  (C) the maturity of any Subordinated Obligation or Senior
         Obligation shall be accelerated, or any Subordinated Obligation or any
         Senior Obligation shall be modified, supplemented or amended in any
         respect, or any right under any of the Collateral Agency Agreement, the
         Indenture, any other Transaction Document, any other Financing Document
         or any other agreement or instrument referred to herein or therein
         shall be waived or any other guarantee of any Subordinated Obligation
         or any Senior Obligation or any security therefor shall be released or
         exchanged in whole or in part or otherwise dealt with; or

                  (D) any lien or security interest granted to, or in favor of,
         the Collateral Agent, the Depositary Bank or any Senior Party as
         security for any Subordinated Obligation or any Senior Obligation shall
         fail to be perfected.

         (vii) Notice to Subordinated Debt Providers. The Company shall give
prompt written notice to each Subordinated Debt Provider of any fact known to
the Company that would prohibit the making of any payment to it in respect of
the Subordinated Obligations. Notwithstanding the provisions of these Terms of
Subordination, no Subordinated Debt Provider shall be charged with knowledge of
the existence of any facts that would prohibit the making of any payment to it
in respect of the Subordinated Obligations, unless and until such Subordinated
Debt Provider shall have received written notice thereof from the Company or a
Senior Party or from any trustee, fiduciary or agent therefor; and, prior to the
receipt of any such written notice, each Subordinated Debt Provider shall be
entitled in all respects to assume that no such facts exist.

         Each Subordinated Debt Provider shall be entitled to rely on the
delivery to it of a written notice by a Person representing itself to be a
Senior Party (or a trustee, fiduciary or agent therefor) or the Collateral Agent
to establish that such notice has been given by a Senior Party (or a trustee,
fiduciary or agent therefor).

         (viii) Reliance on Judicial Order or Certificate of Liquidation Agent.
Upon any payment or distribution of assets of the Company referred to in these
Terms of Subordination, the Subordinated Debt Providers shall be entitled to
rely upon any order or decree entered by any court of competent jurisdiction in
which such insolvency, bankruptcy, receivership, liquidation, reorganization,
dissolution, winding up or similar case or proceeding is pending, or a
certificate of the trustee in bankruptcy, receiver, liquidating trustee,
custodian, assignee for the benefit of creditors, agent or other Person making
such payment or distribution, delivered to the Subordinated Debt Providers, for
the purpose of ascertaining the Persons entitled to participate in such payment
or distribution, the Senior Parties and other indebtedness of the Company, the
amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to these Terms of
Subordination.

         (ix) Specific Performance. Each of the Senior Parties may demand
specific performance of these terms of subordination, whether or not the Company
shall have complied with any of the provisions hereof applicable to them at any
time when the Subordinated Debt Provider shall have failed to comply with any of
such provisions applicable to it. The

                                    2.2 - 5



Subordinated Debt Providers hereby irrevocably waive any defense based on the
adequacy of a remedy at law, which might be asserted as a bar to such remedy of
specific performance.

         (x) Participation of Subordinated Debt Providers. So long as any of the
Senior Obligations shall remain unpaid or otherwise unsatisfied, no Subordinated
Debt Provider shall commence or join with any creditor other than the Collateral
Agent in commencing any proceeding referred to above for the payment of any
amounts which otherwise would be payable or deliverable upon or with respect to
the Subordinated Obligations.

         (xi) Survival. The obligations of the Company under these Terms of
Subordination shall survive the repayment of the Subordinated Obligations.

         (xii) Headings. The section headings appearing herein are included
solely for convenience of reference and are not intended to affect the
interpretation of any provision of these Terms of Subordination.

                                FORM OF GUARANTY


         GUARANTY (this "Guaranty"), made and delivered as of ___________, ____
by THE AES CORPORATION, a Delaware corporation (the "Guarantor").

                                    RECITALS


         A. AES Ironwood, L.L.C. (the "Company"), a Delaware limited liability
company and an indirect subsidiary of Guarantor (the "Guaranteed Party"),
certain parties providing financing to the Company (the "Financing Parties") and
IBJ Whitehall Bank & Trust Company, as Collateral Agent on behalf of the
Financing Parties, have entered into a Collateral Agency and Intercreditor
Agreement, dated as of June 1, 1999 (as the same may be amended, supplemented or
otherwise modified from time to time, the ("Collateral Agency Agreement").

         B. Section 3.6 of the Collateral Agency Agreement provides that the
Company may from time to time under certain circumstances and upon certain
conditions, one of which is the provision of this Guaranty to the Guaranteed
Party, withdraw monies on deposit in, or credited to, any of the Available
Accounts.

         C. The Guarantor is entering into this Guaranty in order to support the
repayment obligations of the Company under Section 3.6 of the Collateral Agency
Agreement for the Advance made on [INSERT DATE] in the amount of $[INSERT
AMOUNT] (the "Guaranteed Obligations").

                                    AGREEMENT

         In consideration of the foregoing and of other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
Guarantor hereby agrees for the benefit of the Guaranteed Party as follows:

         SECTION 1. Definitions. Unless otherwise defined herein, all terms used
herein which are defined in the Collateral Agency Agreement shall have their
respective meanings as therein defined.

         SECTION 2. Guaranty. The Guarantor hereby unconditionally and
irrevocably guarantees, as the primary obligor and not merely as surety, to and
for the benefit of the Guaranteed Party, punctual and full payment by the
Company of the Guaranteed Obligations as and when the same shall become due and
payable in accordance with the terms of the Collateral Agency Agreement. The
guaranty contained herein is an absolute, unconditional, present and continuing
guaranty of payment, and not of collection, is in no way conditioned or
contingent upon any attempt to collect from or enforce payment by the Company or
upon any other event, contingency or circumstance whatsoever, and shall be
binding upon and against the Guarantor without regard to the validity or
enforceability of the Collateral Agency Agreement. If, for any reason
whatsoever, the Company shall fail or be unable duly, punctually and fully to
pay any

                                    3.6(a)-1



Guaranteed Obligation as and when the same shall become due and payable, the
Guarantor shall forthwith pay or cause to be paid such Guaranteed Obligation
to the Guaranteed Party. Such amount will not be paid out of funds or other
assets of the Company.

         SECTION 3. Obligations Absolute and Unconditional, Continuing, Etc. The
Guarantor agrees that the obligations of the Guarantor set forth in this
Guaranty shall be direct obligations of the Guarantor, and such obligations
shall be absolute and unconditional, shall not be subject to any counterclaim,
set-off, deduction, diminution, abatement, recoupment, suspension, deferment,
reduction or defense (other than full and strict compliance by the Guarantor
with its obligations hereunder) based upon any claim the Guarantor or any other
Person may have against the Guaranteed Party, the Company or any other Person,
and shall remain in full force and effect without regard to, and shall not be
released, discharged or in any way affected or impaired by, any circumstance or
condition whatsoever (other than full and strict compliance by the Guarantor
with its obligations hereunder), whether or not the Guarantor shall have any
knowledge or notice thereof, including, without limitation: (i) any amendment or
modification of or supplement to or other change in the Collateral Agency
Agreement or any other Financing Document; (ii) any failure, omission or delay
on the part of the Company or the Guaranteed Party to conform or comply with any
term of the Collateral Agency Agreement; (iii) any waiver, consent, extension,
indulgence, compromise, release or other action or inaction under or in respect
of the Collateral Agency Agreement or any other Financing Document or any
obligation or liability of the Company or the Guaranteed Party, or any exercise
or non-exercise of any right, remedy, power or privilege under or in respect of
any such instrument or agreement or any such obligation or liability; (iv) any
bankruptcy, insolvency, reorganization, arrangement, readjustment, liquidation
or similar proceeding with respect to the Company or the Guaranteed Party or any
of their respective properties, or any action taken by any Guaranteed Party or
receiver or by any court in any such proceeding; (v) any discharge, termination,
cancellation, frustration, irregularity, invalidity or unenforceability, in
whole or in part, of the Collateral Agency Agreement or any other Financing
Document or any term or provision thereof; (vi) any merger or consolidation of
the Company or the Guarantor into or with any other corporation or any sale,
lease or transfer of all or any of the assets of the Company or the Guarantor to
any other Person; (vii) any change in the ownership of the Company; (viii) to
the extent as may be waived under Applicable Law, the benefit of all principles
or provisions of law, statutory or otherwise, which may be in conflict with the
terms hereof; (ix) the occurrence of any condition affecting (adversely or
otherwise) the value of the Guarantor's or the Company's property; or (x) to the
extent permitted under Applicable Law, any other occurrence or circumstance
whatsoever, whether similar or dissimilar to the foregoing, which might
otherwise constitute a legal or equitable defense or discharge of the
liabilities of a guarantor or surety or which might otherwise limit recourse
under this Guaranty against the Guarantor. The obligations of the Guarantor set
forth herein constitute the full recourse obligations of the Guarantor
enforceable against it to the full extent of all its assets and properties.
Without limiting the generality of the foregoing, the Guarantor agrees that (a)
repeated and successive demands may be made and recoveries may be had hereunder
as and when, from time to time, the Company shall default under or fail to
comply with the terms of Section 3.6 of the Collateral Agency Agreement and that
notwithstanding the recovery hereunder for or in respect of any given default or
failure to so comply by the Company under the Collateral Agency Agreement, this
Guaranty shall remain in force and effect and shall apply to each and

                                    3.6(a)-2



every subsequent default, and (b) if any Guaranteed Obligation is paid by the
Company, and thereafter all or any part of such payment is recovered from the
Guaranteed Party upon the insolvency, bankruptcy or reorganization of the
Company, the liability of the Guarantor hereunder with respect to such
Guaranteed Obligation so paid and recovered shall, notwithstanding any prior
release or termination hereof, continue and remain in full force and effect, or
shall be reinstated, as the case may be, as if, to the extent of such recovery,
such payment had not been made. If (x) an event permitting the exercise of
remedies under the Collateral Agency Agreement shall at any time have occurred
and be continuing and (y) such exercise, or any consequences thereof provided in
the Collateral Agency Agreement shall at any time be prevented by reason of the
pendency against the Company of a case or proceeding under any bankruptcy or
insolvency law, the Guarantor agrees that, solely for purposes of this Guaranty
and its obligations hereunder, the Collateral Agency Agreement shall be deemed
to have been declared in default and all amounts thereunder shall be deemed to
be due and payable, with all the attendant consequences as provided in the
Collateral Agency Agreement as if declaration of default and the consequence
thereof had been accomplished in accordance with the terms thereof, and the
Guarantor shall forthwith pay any amounts guaranteed hereunder.

         SECTION 4. Waiver of Demands, Notices, Etc. The Guarantor hereby
unconditionally waives, to the extent permitted by Applicable Law, (i) notice of
any of the matters referred to in the first sentence of Section 3 hereof; (ii)
all notices which may be required by statute, rule of law or otherwise, now or
hereafter in effect, to preserve any rights against the Guarantor hereunder,
including, without limitation, any demand, proof or notice of non-payment of any
Guaranteed Obligation; (iii) any right to the enforcement, assertion or exercise
of any right, remedy, power or privilege under or in respect of the Collateral
Agency Agreement; (iv) notice of acceptance of this Guaranty, demand, protest,
presentment, notice of default and any requirement of diligence; (v) any
requirement to exhaust any remedies or to mitigate any damages resulting from
default by the Company under the Collateral Agency Agreement; (vi) the benefit
of any and all Applicable Laws which are or might be in conflict with the terms
of this Guaranty; and (vii) any other circumstance whatsoever which might
otherwise constitute a legal or equitable discharge, release or defense of a
guarantor or surety, or which might otherwise limit recourse under this Guaranty
against the Guarantor.

         SECTION 5. Subrogation. The Guarantor shall be subrogated to all rights
of the Guaranteed Party in respect of any amounts paid by the Guarantor pursuant
to the provisions of this Guaranty; provided, however, that the Guarantor shall
be entitled to enforce, or to receive any payments arising out of or based upon,
such right of subrogation only after all of the Guaranteed Obligations and any
other payment obligations under the Financing Documents have been paid in full.
Without prejudice to the rights set forth in the preceding sentence, the
Guarantor acknowledges and agrees that no proper payment by the Guarantor under
this Guaranty shall give rise to (i) any claim by the Guarantor against the
Guaranteed Party or (ii) any indebtedness of the Guaranteed Party.

         SECTION 6. Certain Rights and Powers of Guaranteed Party. The
Guaranteed Party shall have all of the rights and remedies available under
Applicable Law and may proceed by appropriate court action to enforce the terms
hereof and to recover damages for the breach

                                    3.6(a)-3



hereof. Each and every remedy of the Guaranteed Party shall, to the extent
permitted by law, be cumulative and shall be in addition to any other remedy now
or hereafter existing at law or in equity. At the option of the Guaranteed Party
and upon notice to the Guarantor, the Guarantor may be joined in any action or
proceeding commenced by such Guaranteed Party against the Company in respect of
any Guaranteed Obligation, and recovery may be had against the Guarantor in such
action or proceeding or in any independent action or proceeding against the
Guarantor, without any requirement that such Guaranteed Party first assert,
prosecute or exhaust any remedy or claim against the Company.

         SECTION 7. Representations, Warranties. The Guarantor represents and
warrants to the Guaranteed Party, on and as of the date hereof:

         (h) There is no action, suit or proceeding pending or, to the knowledge
