SECTION 2.3                EXECUTION AND AUTHENTICATION OF LESSOR NOTES

such Lessor Note such Person may not have been an authorized signatory of the
Owner Lessor. No Lessor Note shall be secured by or be entitled to any benefit

there appears thereon a certificate of authentication substantially in the form
set forth in Exhibit D to this Lease Indenture (or in the appropriate form
provided for in any supplement hereto executed pursuant to Section 2.6 hereof),

principal amounts specified in Schedule I to this Lease Indenture, upon a
written order of the Owner Lessor signed on its behalf by the Owner Manager. The
Lease Indenture Trustee shall authenticate and deliver Subsequent Lessor Notes,

Manager and satisfaction of the conditions specified in Section 2.6 hereof. Such
order shall specify the principal amount of the Subsequent Lessor Notes to be
authenticated and the date on which the original issue of Subsequent Lessor
Notes is to be authenticated.

SECTION 2.4                ISSUANCE AND TERMS OF THE INITIAL LESSOR NOTES

         (a) There shall be issued to the Lender the Initial Lessor Notes, dated

that is 1% per annum in excess of the rate then in effect.

SECTION 2.5                PAYMENTS FROM INDENTURE ESTATE ONLY; NO PERSONAL
                           LIABILITY OF THE OWNER PARTICIPANT SECURITY AGENT
                           OR THE LEASE INDENTURE TRUSTEE

                  Except as may otherwise specifically be provided in this Lease
Indenture or in the Participation Agreement, all payments to be made in respect
of the Lessor Notes or under this Lease Indenture shall be made only from the
Indenture Estate, and the Owner Lessor shall have no obligation for the payment
thereof except to the extent that there shall be sufficient income or proceeds
from the Indenture Estate to make such payments in accordance with the terms of
Section 3

                                        21


<Page>

hereof, and the Owner Participant shall not have any obligation for
payments in respect of the Lessor Notes or under this Lease Indenture. The Lease
Indenture Trustee, the Security Agent, each Noteholder and the issuer of the
Debt Service Reserve Letter of Credit, by its acceptance thereof, agrees that it
will look solely to the income and proceeds from the Indenture Estate to the
extent available for distribution to the Lease Indenture Trustee, the Security
Agent, or such Noteholder or the issuer of the Debt Service Reserve Letter of
Credit, as the case may be, as herein provided and that, except as expressly
provided in this Lease Indenture or the Participation Agreement, (x) none of the
Owner Participant, the Trust Company, the Security Agent, or the Lease Indenture
Trustee, or any Affiliate of any thereof, shall be personally liable to such
Noteholder or the issuer of the Debt Service Reserve Letter of Credit for any
amounts payable hereunder, under such Lessor Note or for any performance to be
rendered under any Indenture Estate Document or for any liability under any
Indenture Estate Document, and (y) such amounts shall be non-recourse to the
assets of each of the Owner Participant, the Security Agent, the Trust Company
or the Lease Indenture Trustee or the issuer of the Debt Service Reserve Letter
of Credit, or any Affiliate of any thereof. Without prejudice to the foregoing,
the Owner Lessor will duly and punctually pay or cause to be paid the principal
of, premium (including, without limitation, Make-Whole Premium), if any, and
interest on all Lessor Notes according to their terms and the terms of this
Lease Indenture. Nothing contained in this Section 2.5 limiting the liability of
the Owner Lessor shall derogate from the right of the Lease Indenture Trustee
the Security Agent, the Noteholders and the issuer of the Debt Service Reserve
Letter of Credit to proceed against the Indenture Estate to secure and enforce
all payments and obligations due hereunder and under the Indenture Estate
Documents and the Lessor Notes.

                  In furtherance of the foregoing, to the fullest extent
permitted by law, each Noteholder (and each assignee of such Person) and the
issuer of the Debt Service Reserve Letter of Credit, by their acceptance
thereof, agrees, as a condition to its being secured under this Lease Indenture,
that neither they nor the Lease Indenture Trustee will exercise any statutory
right to negate the agreements set forth in this Section 2.5.

                  Nothing herein contained shall be interpreted as affecting the
representations, warranties or agreements of the Owner Lessor expressly made set
forth in the Participation Agreement or the Lessor LLC Agreement.

SECTION 2.6                SUBSEQUENT LESSOR NOTES

         (a) The Owner Lessor may, subject to the conditions hereafter provided

the purpose of (i) providing funds for a Supplemental Financing pursuant to
Section 12.1 of the


                                        22

Participation Agreement (Subsequent Lessor Notes issued for such purpose, the
"ADDITIONAL LESSOR NOTES") or (ii) refinancing the Lessor Notes or other
Subsequent Lessor Notes pursuant to Section 12.2 of the Participation
Agreement (Subsequent Lessor Notes issued for such purpose, the "NEW LESSOR
NOTES").

         (b) Before any Subsequent Lessor Notes shall be issued under the
provisions of this Section 2.6, the Owner Lessor shall have delivered to the
Lease Indenture Trustee, not less than 5 (15 days in the case of New Lessor

proposed date of issuance of such Subsequent Lessor Notes, a request and
authorization to issue such Subsequent Lessor Notes, which request and

Subsequent Lessor Notes from the Lessor Notes theretofore issued, be dated their
respective dates of issuance, bear interest at such rates (which may be either
fixed or floating) as shall be agreed between the Facility Lessee and the Owner
Lessor, and shall be stated to be payable by their terms not later than the
latest date permitted therefore under Section 12.1 or 12.2 of the Participation
Agreement, as the case may be.

Subsequent Lessor Notes or the rate or rates of interest thereon, such
Subsequent Lessor Notes shall be on a parity with, and shall be entitled to the
same benefits and security of this Lease Indenture, and shall be subject to the
same terms hereof, as the other Lessor Notes issued pursuant to the terms
hereof.

         (d) The terms, provisions and designations of such Subsequent Lessor
Notes shall be set forth in a supplement to this Lease Indenture executed by the
Owner Lessor, the Lease Indenture Trustee and the Security Agent. Such
Subsequent Lessor Notes shall be executed, delivered and registered as provided
in this Lease Indenture, but before such Subsequent Lessor Notes shall be
delivered and registered there shall be delivered to the Lease Indenture Trustee
and the Security Agent, in addition to other documents and certificates required
by this Section 2.6, the following, all of which shall be dated as of the date
of the supplement to this Lease Indenture:

                  (i) a copy of such supplement (which shall include
         the form of such series of Subsequent Lessor Notes);

         such supplement, together with UCC lien searches, supplemental title
         reports, opinions, title insurance endorsements and such other evidence

         and such supplement provide a first-priority perfected lien and
         security interest, subject to Permitted Liens, in the Indenture Estate
         for the full amount of all Lessor Notes outstanding, including all
         Subsequent Lessor Notes described in such supplement and the issuer of
         the Debt Service Reserve Letter of Credit;

         Facility Lessee stating that (A) no Lease Default or Lease Event of
         Default has occurred and is continuing, (B) the conditions in respect
         of the issuance of such Subsequent Lessor Notes contained in this
         Section 2.6 have been satisfied, (C) the Basic Lease Rent and the
         Termination Value are calculated to be sufficient to pay all the
         outstanding Lessor Notes, after taking into account the issuance of
         such Subsequent Lessor Notes and any related prepayment of Lessor Notes
         theretofore outstanding and (D) all conditions to the Supplemental
         Financing or refinancing contained in Section 12.1 or 12.2 of the

         enforceable in accordance with their terms.

of 1939, as amended, and all Lessor Notes issued hereunder shall be endorsed
with a legend which shall read substantially as follows:

         THIS NOTE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AND

                  All Lessor Notes issued and outstanding hereunder shall rank
on a parity with each other and with the issuer of the Debt Service Reserve
Letter of Credit and shall as to each other be secured equally and ratably by
this Lease Indenture, without preference, priority or distinction of any thereof
over any other by reason of difference in time of issuance or otherwise.

SECTION 2.10               ACCEPTANCE OF THE LEASE INDENTURE TRUSTEE AND
                           APPOINTMENT OF THE SECURITY AGENT

                  (a) Each Noteholder, by its acceptance of a Lessor Note, shall

representatives hereby designates and appoints The Bank of New York as the
security agent for such Lease Indenture Secured Parties under the Lease
Indenture, and authorizes The Bank of New York in such capacity to take such
action on its


                                        25


<Page>

behalf under the provisions of the Lease Indenture and to exercise
such powers and perform such duties as are expressly delegated to it by the
terms of this Lease Indenture, together with such other powers as are incidental
thereto. Notwithstanding any provision to the contrary elsewhere in this Lease
Indenture, the Security Agent shall not have any duties or responsibilities,
except those expressly set forth herein, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Lease Indenture or otherwise exist against the Security Agent.

SECTION 2.11               REGISTRAR AND PAYING AGENT

         (a) The Owner Lessor shall maintain in the Borough of Manhattan, the
City of New York, an office or agency where Lessor Notes may be presented for
registration of transfer ("REGISTRAR") and an office or agency where Lessor
Notes may be presented for payment ("PAYING AGENT"). The Registrar shall keep a
register of the Lessor Notes and of their transfer. The Owner Lessor may appoint
one or more co-registrars and one or more additional paying agents. The term
Registrar includes any co-registrar and the term Paying Agent includes any
additional paying agent. The Owner Lessor may change any Paying Agent without
notice to any Noteholder. The Owner Lessor shall notify the Security Agent and
the Lease Indenture Trustee in writing of the name and address of any Agent not
a party to this Lease Indenture. If the Owner Lessor fails to appoint or
maintain another entity as Registrar or Paying Agent, the Lease Indenture
Trustee shall act as such.

         (b) The Owner Lessor initially appoints the Lease Indenture Trustee to
act as the Registrar and Paying Agent and to act as Custodian with respect to
the Lessor Notes.

         (c) The Security Agent shall deposit with the Lease Indenture Trustee
for as long as the Lessor Note Indenture is outstanding, (or to the Paying Agent
if applicable) a sum sufficient to pay such principal and interest, and premium,
if any, when so becoming due. The Owner Lessor shall require each Paying Agent
(other than the Lease Indenture Trustee) to agree in writing that the Paying
Agent shall hold in trust for the benefit of Noteholders or the Lease Indenture
Trustee all money held by the Paying Agent for the payment of principal of or
interest on the Lessor Notes and shall notify the Lease Indenture Trustee of any
default by the Security Agent in making any such payment.

SECTION 2.12               PAYING AGENT TO HOLD MONEY IN TRUST

                  The Owner Lessor shall require each Paying Agent other than
the Lease Indenture Trustee to agree in writing that the Paying Agent will hold
in trust for the benefit of Noteholders or issuer of the Debt Service Reserve
Letter of Credit,


                                        26


<Page>

if applicable, and all money held by the Paying Agent for the payment of
principal on, premium, if any, or interest on the Lessor Notes, and will
notify the Lease Indenture Trustee in writing of any default  by the
Security Agent in making any such payment. While any such default continues,
the Lease Indenture Trustee may require a Paying Agent to pay all money held
by it to the Lease Indenture Trustee. The Owner Lessor at any time may require
a Paying Agent to pay all money held by it to the Lease Indenture Trustee.
Upon payment over to the Lease Indenture Trustee, the Paying Agent shall have no
further liability for the money.

SECTION 2.13               [RESERVED]

SECTION 2.14               REPLACEMENT LESSOR NOTES

                  If any mutilated Lessor Note is surrendered to the Lease
Indenture Trustee or the Owner Lessor and the Lease Indenture Trustee receives
evidence to its satisfaction of the destruction, loss or theft of any Lessor
Note, the Owner Lessor shall issue and the Lease Indenture Trustee, upon receipt
of an Authentication Order, shall authenticate a replacement Lessor Note and
deliver in lieu of such Lessor Note, a new Lessor Note, dated the same date as
such Lessor Note and of like tenor and principal amounts. If required by the
Lease Indenture Trustee or the Owner Lessor, an indemnity Lessor Note must be
supplied by the Noteholder that is sufficient in the judgment of the Lease
Indenture Trustee and the Owner Lessor to protect the Owner Lessor, the Lease
Indenture Trustee, any Agent and any authenticating agent from any loss that any
of them may suffer if a Lessor Note is replaced. The Owner Lessor and the Lease
Indenture Trustee may charge for their expenses in replacing a Lessor Note.

                  Every replacement Lessor Note is an additional obligation of
the Owner Lessor and shall be entitled to all of the benefits of this Lease
Indenture equally and proportionately with all other Lessor Notes duly issued
hereunder.

SECTION 2.15               OUTSTANDING LESSOR NOTES

                  The Lessor Notes outstanding at any time are all the Lessor
Notes authenticated by the Lease Indenture Trustee except for those canceled by
it, those delivered to it for cancellation, and those described in this Section
as not outstanding. Except as set forth in Section 2.16 hereof, a Lessor Note
does not cease to be outstanding because the Owner Lessor or an Affiliate of the
Owner Lessor holds the Lessor Note.

                                        27


<Page>

                  If a Lessor Note is replaced pursuant to Section 2.14 hereof,
it ceases to be outstanding unless the Lease Indenture Trustee receives proof
satisfactory to it that the replaced Lessor Note is held by a bona fide
purchaser.

                  If the principal amount of any Lessor Note is considered paid
under Section 5.1 hereof, it ceases to be outstanding and interest on it ceases
to accrue.

                  If the Paying Agent holds, on a redemption date or maturity
date, money sufficient to pay Lessor Notes payable on that date, then on and
after that date such Lessor Notes shall be deemed to be no longer outstanding
and shall cease to accrue interest.

SECTION 2.16               TREASURY LESSOR NOTES

                  In determining whether the Noteholders of the required
principal amount of Lessor Notes have concurred in any direction, waiver or
consent, Lessor Notes owned by the Owner Lessor, or by any Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with the Owner Lessor shall be considered as though not outstanding,
except that for the purposes of determining whether the Lease Indenture Trustee
shall be protected in relying on any such direction, waiver or consent, only
Lessor Notes that the Lease Indenture Trustee knows are so owned shall be so
disregarded.

SECTION 2.17               [RESERVED]

SECTION 2.18               CANCELLATION

                  The Owner Lessor at any time may deliver Lessor Notes to the
Lease Indenture Trustee for cancellation. The Registrar and Paying Agent shall
forward to the Lease Indenture Trustee any Lessor Notes surrendered to them for
registration of transfer, exchange or payment. The Lease Indenture Trustee and
no one else shall cancel all Lessor Notes surrendered for registration of
transfer, exchange, payment, replacement or cancellation and shall destroy
canceled Lessor Notes (subject to the record retention requirement of the
Exchange Act). Certification of the destruction of all canceled Lessor Notes
shall be delivered (at the expense of the Owner Lessor) to the Owner Lessor. The
Owner Lessor may not issue New Lessor Notes to replace Lessor Notes that it has
paid or that have been delivered to the Lease Indenture Trustee for
cancellation.

SECTION 2.19               DEFAULTED INTEREST

                  If the Owner Lessor defaults in a payment of interest on the
Lessor Notes, it shall pay the defaulted interest in any lawful manner plus, to
the extent lawful, interest payable on the defaulted


                                        28


<Page>

interest, to the Noteholders on a subsequent special record date, in each
case at the rate provided in the Lessor Notes and in Section 5.1 hereof. The
Owner Lessor shall notify the Security Agent and the Lease Indenture Trustee
in writing of the amount of defaulted interest proposed to be paid on each
Lessor Note and the date of the proposed payment. The Owner Lessor shall fix
or cause to be fixed each such special record date and payment date, PROVIDED

notify the Security Agent and the Lease Indenture Trustee of its intention to
assume all of the Lessor Notes in whole (but not in part) pursuant to and in
accordance with this Section 2.21. In the event of the occurrence of an
Assumption Event and provided each of the conditions set forth below have been
satisfied, all of the obligations and liabilities of the Owner Lessor under this
Lease Indenture and each Lessor Note shall be assumed by the Facility Lessee and

formality whatsoever from all obligations and liabilities under this Lease
Indenture and each Lessor Note:

         and be continuing after giving effect to such assumption;

                  (ii) the Lease Indenture Trustee shall have received a
         supplement to this Lease Indenture which shall, among other things, (A)
         confirm the release of the Owner Lessor thereby effected and (B)
         contain provisions appropriately amending this Lease Indenture: (1) to
         reflect the fact that the obligations of the Owner Lessor under this
         Lease Indenture have been assumed directly by the Facility Lessee, (2)
         to incorporate herein such provisions from the Facility Lease, the
         Facility Site Lease and the Participation Agreement as shall be
         appropriate, including covenants substantially identical to those set
         forth in the Facility Lease and (3) as otherwise necessary to reflect
         the foregoing provisions and preserve, protect and maintain the Lien on
         the Indenture Estate (such supplement, the "ASSUMPTION AGREEMENT");

                  (iii) the Lease Indenture Trustee shall have received an
         opinion of counsel to the Facility Lessee (with customary
         qualifications and limitations and otherwise reasonably satisfactory to
         the Lease Indenture Trustee), addressed to the Lease Indenture Trustee
         and the Noteholders of the Lessor Notes, to the effect that (A) the
         Assumption Agreement and each other instrument, document or agreement
         executed and delivered by the Facility Lessee in connection with the
         assumption contemplated by the Assumption Agreement (collectively, the
         "ASSUMPTION DOCUMENTS") have been duly authorized, executed and
         delivered by the Facility Lessee, (B) each Assumption Document and the
         assumption contemplated thereby do not contravene (1) the Organic
         Documents of the Facility Lessee, (2) any contractual obligation of the
         Facility Lessee or (3) Requirements of Law, (C) no Governmental
         Approval is necessary or required in connection with any Assumption
         with any Assumption Document or the assumption contemplated thereby
         (or, if any such Governmental Approval is necessary or required that
         the same has been duly obtained and is final and in full force and
         effect and any period for the filing of notice of rehearing or
         application for judicial review of the issuance of such Governmental
         Approval has expired without any such notice or application having been
         made), (D) each Assumption Document is a legal, valid and binding
         obligation of the Facility Lessee, enforceable in accordance with its
         terms (except as limited by bankruptcy, insolvency or similar laws of
         general application affecting the enforcement of creditors' rights
         generally and equitable principles), (E) unless the Facility Lessee has
         elected to provide to the Lease Indenture Trustee an indemnity against
         the risk that such assumption of the Lessor Notes will cause a Tax
         Event to occur as to any direct or indirect holder of a Lessor Note
         (including any holder of the Bonds), such Assumption Agreement and the
         assumption of the Notes thereunder shall not cause a Tax Event to occur
         as to any direct or indirect holder of any Lessor Note (including any
         Fundco Bondholders) and (F) the lien of this Lease Indenture will
         continue to be a first priority perfected lien on the Indenture Estate;

                  (iv) the Lease Indenture Trustee shall have received copies of
         all Governmental Approvals (if any) referred to in the opinion of
         counsel referred to in clause (iii) above;

                  (v) the Lease Indenture Trustee shall have received UCC lien
         searches, supplemental title reports, opinions and such other evidence
         as may reasonably be required by the Lease Indenture Trustee
         demonstrating that no impairment exists or will exist to the first
         priority perfected lien and security interest in the Undivided
         Interest; and

                  (vi) the Lease Indenture Trustee shall have received ratings
         letters from each of Moody's and S&P to the effect that the then
         existing rating of the Bonds will not be downgraded as a result of such
         assumption.

         (b) Notice of any assumption of the Lessor Notes shall be given by the
Lease Indenture Trustee to the Noteholders as promptly as practicable after the
Lease Indenture Trustee has received notice thereof in accordance with the first
sentence of section 2.21(a) hereof.

                  accrued but unpaid interest and premium, if any, thereon to
                  the date of distribution (as well as any interest on overdue

                  or amounts as shall be required to reimburse each such
                  Noteholder for any tax, expense, charge or other loss
                  (including, without limitation, all amounts to be expended at

                  Noteholder, liquidated or otherwise, upon such Lease Indenture
                  Event of Default shall be applied by such Noteholder in
                  reimbursement of such expenses; and

         respect of the "FINANCIAL ASSETS" (within the meaning of Section
         8-102(a)(9) of the UCC) credited to each Note Account, (D) all property
         delivered to the Security Agent pursuant to this Lease Indenture or any
         other Operative Document will be held by the Security Agent and
         promptly credited to each Note Account by an appropriate entry in its
         records in accordance with this Lease Indenture, (E) all "FINANCIAL
         ASSETS" (within the meaning of Section 8-102(a)(9) of the UCC) in
         registered form or payable to or to the order of and credited to each
         Note Account shall be registered in the name of, payable to or to the
         order of, or indorsed to, the Security Agent or in blank, or credited
         to another securities account maintained in the name of the Security
         Agent, and in no case will any financial asset credited to any of the
         Note Accounts be registered in the name of, payable to or to the order
         of, or indorsed to, the Owner Lessor except to the extent the foregoing
         have been subsequently indorsed by the Owner Lessor to the Account Bank
         or in blank and (F) the Security Agent shall not change the name or
         account number of the Security Agent's Account without the prior
         written consent of the Security Agent.

                  (ii) FINANCIAL ASSETS ELECTION. The Security Agent agrees that
         each item of property (including any security, instrument or
         obligation, share, participation, interest or other property
         whatsoever) credited to the Security Agent's Account shall be treated
         as a "FINANCIAL ASSET" within the meaning of Section 8-102(a)(9) of the
         UCC.

                  (iii) ENTITLEMENT ORDERS. Notwithstanding anything in this
         Lease Indenture to the contrary, if at any time the Security Agent
         shall receive any "ENTITLEMENT ORDER" (within the meaning of Section
         8-102(a)(8) of the UCC) or any other order directing the transfer or
         redemption of any financial asset relating to the Security Agent's
         Account, the Security Agent shall comply with such entitlement order or
         other order without further consent by the Owner Lessor or any other
         Person. The parties hereto hereby agree that the Security Agent shall
         have "CONTROL" (within the meaning of Section 8-106(d) of the UCC) of
         the Owner Lessor's "SECURITY ENTITLEMENTS"


                                      37

<Page>

         (within the meaning of Section 8-102(a)(17) of the UCC) with respect to
         the financial assets credited to the Security Agent's Account and the
         Owner Lessor hereby disclaims any entitlement to claim "CONTROL" of
         such "SECURITY ENTITLEMENTS". Unless a Lease Indenture Event of Default
         shall have occurred and is continuing, the Lease Indenture Trustee
         shall not deliver any entitlement order directing the transfer or
         redemption of any financial asset relating to the Security Agent's
         Account.

                  (iv) SUBORDINATION OF LIEN; WAIVER OF SET-OFF. In the event
         that the Security Agent has or subsequently obtains by agreement,
         operation of law or otherwise a lien or security interest in the
         Security Agent's Account or any security entitlement credited thereto,
         the Security Agent agrees that such lien or security interest shall be
         subordinate to the lien and security interest of the Security Agent for
         the benefit of the Lease Indenture Secured Parties. The financial
         assets standing to the credit of the Lease Indemnitee's Lease Indenture
         Trustee's Account will not be subject to deduction, set-off, banker's
         lien, or any other right in favor of any Person other than the Security
         Agent for the benefit of the Lease Indenture Secured Parties (except
         for the face amount of any checks which have been credited to the Note
         Accounts but are subsequently returned unpaid because of uncollected or
         insufficient funds).

                  (v) NO OTHER AGREEMENTS. The Security Bank and the Owner
         Lessor have not entered into any agreement with respect to the Note
         Accounts or any financial assets credited to the Note Accounts other
         than this Lease Indenture. The Security Agent has not entered into any
         agreement with the Owner Lessor or any other Person purporting to limit
         or condition the obligation of the Security Agent to comply with
         entitlement orders originated by the Security Agent in accordance with
         Section 3.8(a)(iii) hereof. In the event of any conflict between this
         Section 3.8 or any other agreement now existing or hereafter entered
         into, the terms of this Section 3.8 shall prevail.

                  (vi) NOTICE OF ADVERSE CLAIMS. Except for the claims and
         interest of the Security Agent for the benefit of the Lease Indenture
         Secured Parties and the Owner Lessor in the Note Accounts, the Security
         Agent does not know of any claim to, or interest in, the Note Accounts
         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
         the Note Accounts or in any financial asset credited thereto, the
         Security Agent will promptly notify the Security Agent and the Owner
         Lessor in writing thereof.

                  (vii) RIGHTS AND POWERS OF THE SECURITY AGENT. The rights and
         powers granted by the Lease Indenture Secured Parties to the Security
         Agent have been granted in order to perfect its lien and security
         interests in the Security Agent's Account, are powers coupled with an
         interest and will neither be affected by the bankruptcy of the Owner
         Lessor nor the lapse of time.

         (b) LIMITED RIGHTS OF THE OWNER LESSOR. The Owner Lessor shall not have
any rights against or to monies held in the Note Accounts, as third party
beneficiary or otherwise, or any right to direct the Security Agent or the
Security Agent to apply or transfer monies in the Note Accounts, except the
right to receive or make requisitions of monies held by the Security Agent and
to direct investments of monies as provided in Section 3.10 hereof, as provided
in this Lease Indenture. Except as provided in this Lease Indenture, in no event
shall any amounts or Cash Equivalent Investments deposited in or credited to the
Note Accounts be registered in the name of the Owner Lessor, payable to the
order of the Owner Lessor or specially indorsed to the Owner Lessor except to
the extent that the foregoing have been specially indorsed to the Security Agent
or in blank.

SECTION 3.9           EXERCISE OF POWERS; INSTRUCTIONS OF REQUIRED LEASE
                      INDENTURE SECURED PARTIES.

                  (a) All of the powers, remedies and rights of the Security
Agent set forth in or contemplated by this Agreement may be exercised by the
Security Agent as though set forth in full herein, and all of the powers,
remedies and rights of the Security Agent and the Lease Indenture Secured
Parties as set forth herein.

                  (b) Following the delivery of a direction of acceleration
under Section 7.4 hereof to the Security Agent, during any Event of Default, the
Required Lease Indenture Secured Parties may deliver a "NOTICE OF ACTION" to the
Security Agent directing the Security Agent to exercise one or more of the
rights and remedies available to the Security Agent under this Lease Indenture.
The Security Agent shall deliver to each Lease Indenture Secured Party a copy of
such Notice of Action promptly after receipt thereof. The Security Agent shall
exercise the rights and remedies and take the other actions described in such
Notice of Action at the time or times specified in such Notice of Action.

                  (c) All Proceeds of the Indenture Estate received by the
Security Agent from the exercise of its rights and remedies under this Lease
Indenture shall be applied as set forth in Article 3 hereof.

SECTION 3.10               INVESTMENT OF AMOUNTS HELD BY LEASE INDENTURE
                           TRUSTEE.

                  Any amounts held by the Security Agent pursuant to the
proviso to clause "SECOND" of Section 3.1 hereof, pursuant to Section 3.2 or
Section 3.3 hereof, or pursuant to Section 10 or 11 of the Facility Lease
shall be invested by the Security Agent from time to time in Permitted
Investments identified in written instructions to the Security Agent from the
Owner Lessor, at the expense of the Owner Lessor, if such investments are
reasonably available. Unless otherwise expressly provided in this Lease
Indenture, any income realized as a result of any such investment, net of the
Security Agent's reasonable fees and expenses in making such investment,
shall be held and applied by the Security Agent in the same manner as the
principal amount of such investment is to be applied, and any losses, net of
earnings and such reasonable fees and expenses, shall be charged against the
principal amount invested. The Security Agent shall not be liable for any
loss resulting from any investment required to be made by it under this Lease
Indenture other than by reason of its willful misconduct or gross negligence
as determined by a court of competent jurisdiction in receiving, handling or
disbursing funds, and any such investment may be sold (without regard to its
maturity) by the Security Agent without instructions whenever it reasonably
believes such sale is necessary to make a distribution required by this Lease
Indenture.

                            REDEMPTION AND PREPAYMENT

SECTION 4.1                NOTICES TO LEASE INDENTURE TRUSTEE

                  If the Owner Lessor elects to redeem Lessor Notes pursuant
to the redemption provisions of Section 4.7 or 4.8 hereof, it shall furnish
to the Lease Indenture Trustee, the Security Agent, and for so long as the
Bonds are outstanding, the Bondholder Trustee at least 30 days but not more
than 60 days before a redemption date, an Officer's Certificate setting forth
(i) the clause of this Lease Indenture pursuant to which the redemption shall
occur, (ii) the redemption date, (iii) the principal amount of Lessor Notes
to be redeemed and (iv) the redemption price.

SECTION 4.2                SELECTION OF LESSOR NOTES TO BE REDEEMED

                  If less than all of the Lessor Notes are to be redeemed at
any time, the Lease Indenture Trustee shall select the Lessor Notes to be
redeemed among the Noteholders of the Lessor Notes in compliance with the
requirements of the principal national securities exchange, if any, on which
the Lessor Notes are listed or, if the Lessor Notes are not so listed, on a
PRO RATA basis, by lot or in accordance with any other method the Lease
Indenture Trustee considers fair and appropriate. In the

                                     40

<Page>

event of partial redemption by lot, the particular Lessor Notes to be
redeemed shall be selected, unless otherwise provided herein, not less than
30 nor more than 60 days prior to the redemption date by the Lease Indenture
Trustee from the outstanding Lessor Notes not previously called for
redemption.

                  The Lease Indenture Trustee shall promptly notify the Owner
Lessor and the Security Agent of the Lessor Notes selected for redemption
and, in the case of any Lessor Note selected for partial redemption, the
principal amount thereof to be redeemed. Lessor Notes and portions of Lessor
Notes selected shall be in amounts of $100,000 or whole multiples of $1,000
in excess thereof; except that if all of the Lessor Notes of a Noteholder are
to be redeemed, the entire outstanding amount of Lessor Notes held by such
Noteholder, even if not in the amount of $100,000 or a multiple of $1,000 in
excess thereof, shall be redeemed. Except as provided in the preceding
sentence, provisions of this Lease Indenture that apply to Lessor Notes
called for redemption also apply to portions of Lessor Notes called for
redemption.

SECTION 4.3                NOTICE OF REDEMPTION

                  At least 30 days but not more than 60 days before a
redemption date, the Owner Lessor shall mail or cause to be mailed, by first
class mail, a notice of redemption to each Noteholder whose Lessor Notes are
to be redeemed at its registered address and, for as long as the Bonds are
outstanding, the Bondholder Trustee and each holder of the Bonds
corresponding to the tenor and the principal amount of the Lessor Notes being
redeemed.

                  The notice shall identify the Lessor Notes to be redeemed
and shall state:

         (a)      the redemption date;

         (b)      the redemption price;

         (c) if any Lessor Note is being redeemed in part, the portion of the
principal amount of such Lessor Note to be redeemed and that, after the
redemption date upon surrender of such Lessor Note, a new Lessor Note or
Lessor Notes in principal amount equal to the unredeemed portion shall be
issued upon cancellation of the original Lessor Note;

         (d)      the name and address of the Paying Agent;

         (e)      that Lessor Notes called for redemption must be surrendered
to the Paying Agent to collect the redemption price;

                                     41

<Page>

         (f) that, unless the Owner Lessor defaults in making such redemption
payment, interest on Lessor Notes called for redemption ceases to accrue on
and after the redemption date;

         (g)      the paragraph of the Lessor Notes and/or Section of this
Lease Indenture pursuant to which the Lessor Notes called for redemption are
being redeemed; and

         (h) that no representation is made as to the correctness or accuracy
of the CUSIP number, if any, listed in such notice or printed on the Lessor
Notes.

                  At the Owner Lessor's request, the Lease Indenture Trustee
shall give the notice of redemption in the Owner Lessor's name and at its
expense; PROVIDED, HOWEVER, that the Owner Lessor shall have delivered to the
Lease Indenture Trustee, at least 45 days prior to the redemption date (or
such shorter time period acceptable to the Lease Indenture Trustee), an
Officer's Certificate requesting that the Lease Indenture Trustee give such
notice and setting forth the information to be stated in such notice as
provided in the preceding paragraph.

SECTION 4.4                EFFECT OF NOTICE OF REDEMPTION

                  Once notice of redemption is mailed in accordance with
Section 4.3 hereof, Lessor Notes (and the Bonds corresponding to the tenor
and principal amount of such Lessor Notes) called for redemption become
irrevocably due and payable on the redemption date at the redemption price. A
notice of redemption may not be conditional.

SECTION 4.5                DEPOSIT OF REDEMPTION PRICE

                  One Business Day prior to the redemption date, the Security
Agent shall deposit with the Lease Indenture Trustee or with the Paying Agent
into the Lessor Notes Payment Account money sufficient to pay the redemption
price of and accrued interest on all Lessor Notes to be redeemed on that
date. The Lease Indenture Trustee or the Paying Agent shall promptly return
to the Owner Lessor any money deposited with the Lease Indenture Trustee or
the Paying Agent by the Owner Lessor in excess of the amounts necessary to
pay the redemption price of, and accrued interest on, all Lessor Notes to be
redeemed.

                  If the Owner Lessor complies with the provisions of the
preceding paragraph, on and after the redemption date, interest shall cease
to accrue on the Lessor Notes or the portions of Lessor Notes called for
redemption. If a Lessor Note is redeemed on or after an interest record date
but on or prior to the related interest payment date, then any accrued and
unpaid interest shall be paid to the Person in whose name such Lessor Note
was registered at the close of business on such record

                                     42

<Page>

date. If any Lessor Note called for redemption shall not be so paid upon
surrender for redemption because of the failure of the Owner Lessor to comply
with the preceding paragraph, interest shall be paid on the unpaid principal,
from the redemption date until such principal is paid, and to the extent
lawful on any interest not paid on such unpaid principal, in each case at the
rate provided in the Lessor Notes and in Section 5.1 hereof.

SECTION 4.6                LESSOR NOTES REDEEMED IN PART

                  Upon surrender of a Lessor Note that is redeemed in part,
the Owner Lessor shall issue and, upon receipt of an Authentication Order,
the Lease Indenture Trustee shall authenticate for the Noteholder at the
expense of the Owner Lessor a new Lessor Note equal in principal amount to
the unredeemed portion of the Lessor Note surrendered.

SECTION 4.7                OPTIONAL REDEMPTION

                  The Lessor Notes shall be subject to optional redemption at
any time at a Redemption Price equal to the outstanding principal amount of
the Lessor Notes to be redeemed plus all accrued and unpaid interest thereon
to the Redemption Date, plus the Make-Whole Premium, if any.

SECTION 4.8                MANDATORY REDEMPTION

                  The Lessor Notes will be subject to mandatory redemption
upon the occurrence of a Recovery Event with respect to the Facility, other
than with respect to amounts received by the Owner Lessor in connection with
a Recovery Event for which the Facility Lessee elects to restore or replace
the asset or assets in respect of which such Recovery Event occurred and a
Reinvestment Notice is provided by the Facility Lessee to the Owner
Participant, the Collateral Agent and the Lease Indenture Trustee within 45
days of such Recovery Event (provided that, with respect to any Recovery
Event of $50 million or more, the Independent Engineer shall have certified
as to the reasonableness, in light of Prudent Industry Practice, of the
Facility Lessee's repair and replacement plans as set forth in the Facility
Lessee's Reinvestment Notice relating to such Recovery Event). Any mandatory
redemption of the Lessor Notes will be without premium or penalty at a
Redemption Price equal to the unpaid principal amount thereof plus accrued and
unpaid interest thereon to the Redemption Date.

SECTION 5.1                PAYMENT OF LESSOR NOTES

                  The Owner Lessor hereby covenants and agrees as follows:

         (a) The Owner Lessor will duly and punctually pay the principal of

under the Lessor Notes and this Lease Indenture in accordance with the terms
hereof and thereof and all amounts payable by it to the Lease Indenture
Trustee, the Noteholders and the issuer of the Debt Service Reserve Letter of
Credit under any other Operative Document. Principal, premium, if any, and
interest shall be considered paid on the date due if the Security Agent holds

direction of the Owner Lessor, in immediately available funds and designated
for and sufficient to pay all principal, premium, if any, and interest then
due;

         (b) The Owner Lessor shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Code) on overdue principal at

on the Lessor Notes to the extent lawful; it shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Code) on
overdue installments of interest (without regard to any applicable grace
period) at the same rate to the extent lawful.

Indenture Default, the Owner Lessor will give prompt written notice of such
Lease Indenture Event of Default or Lease Indenture Default to the Facility
Lessee, the Owner Participant, the Lease Indenture Trustee (and the Lease
Indenture Trustee shall thereupon promptly deliver a copy of such notice to
each Noteholder and the Security Agent); and

                  (i) in the event that an Authorized Officer of the Owner
         Lessor shall have actual knowledge of an Event of Loss, then, to the
         extent that the Facility Lessee is not required, pursuant to the
         Facility Lease, to give notice of such event to the Lease Indenture
         Trustee and the Security Agent, the Owner Lessor will give prompt
         written notice of such Event of Loss to the Lease Indenture Trustee
         (and the Lease Indenture Trustee shall thereupon promptly deliver a
         copy of such notice to each Noteholder) and the Security Agent; and

                                     44

<Page>

                  (ii) the Owner Lessor will furnish to the Lease Indenture
         Trustee and the Security Agent true and correct duplicates or copies of
         all reports, notices, requests, demands, certificates, financial
         statements and other instruments furnished to the Owner Lessor under
         the Facility Lease, to the extent that the same shall not have been (or
         are not required to be) furnished to the Lease Indenture Trustee, the
         Noteholders, or the Security Agent pursuant to the Facility Lease or
         the Participation Agreement.

         (d) Except as contemplated by the Operative Documents, the Owner
Lessor will not incur any Indebtedness or engage in any business activity
except with the prior written consent of the Lease Indenture Trustee and
acting on the instructions of the Required Holders.

SECTION 5.2                STAY, EXTENSION AND USURY LAWS

                  The Owner Lessor covenants (to the extent that it may
lawfully do so) that it shall not at any time insist upon, plead, or in any
manner whatsoever claim or take the benefit or advantage of, any stay,
extension or usury law wherever enacted, now or at any time hereafter in
force, that may affect the covenants or the performance of this Lease
Indenture; and the Owner Lessor (to the extent that it may lawfully do so)
hereby expressly waives all benefit or advantage of any such law, and
covenants that it shall not, by resort to any such law, hinder, delay or
impede the execution of any power herein granted to the Security Agent or the
Lease Indenture Trustee, but shall suffer and permit the execution of every
such power as though no such law had been enacted.

SECTION 5.3                PAYMENTS FOR CONSENT

                  The Owner Lessor shall not directly or indirectly, pay or
cause to be paid any consideration, whether by way of interest, fee or
otherwise, to any Noteholder for or as an inducement to any consent, waiver
or amendment of any of the terms or provisions of this Lease Indenture or the
Lessor Notes unless such consideration is offered to be paid or is paid to
all Noteholders of the Lessor Notes that consent, waive or agree to amend in
the time frame set forth in the solicitation documents relating to such
consent, waiver or agreement.

SECTION 5.4                DEBT SERVICE RESERVE ACCOUNT

                  The Owner Lessor shall establish and, so long as any Lessor

payment is made pursuant to Section 6.9 of the Participation Agreement, the
Debt Service Reserve Amount on such date of determination will be 100% of the
projected debt service on

                                     45

the Lessor Notes for the succeeding six-month period, and may be satisfied by
one or a combination of the following: (i) cash or (ii) a letter of credit
issued by a bank or trust company that constitutes Acceptable Credit Support.
Withdrawal of funds from the Debt Service Reserve Account or a draw on the
letter of credit issued pursuant to this Section 5.4 following a Lease Event
of Default remitting from failure to pay any Basic Lease Rent or Supplemental
Lease Rent when due, shall be deemed to be an exercise of the Owner Lessor of
its rights under Section 7.2 hereof (other than clause (i) of the last
proviso of the last sentence of Section 7.2). Any deposit made by the Owner
Lessor into the Debt Service Reserve Account and any re-instatement of the
Debt Service Reserve Letter of Credit other than in connection with the
payment by the Facility Lessee of the related overdue Rent shall be deemed to
be an exercise by the Owner Lessor of its rights under Section 7.2 hereof for
purposes of clause (i) of the last proviso of the last sentence of Section
7.2.

about or be effected by operation of law or pursuant to or in compliance with
any judgment, decree or order of any court or any order, rule or regulation
of any Governmental Authority):

         (a) any Lease Event of Default (other than with respect to (x) a
Rent Default Event, (y) Excepted Payments unless the Facility Lease has been
declared in default by the Owner Lessor or (z) the failure of the Facility
Lessee to maintain insurance in the amounts and on the terms set forth in the
Operative Documents so long as the insurance actually maintained by the
Facility Lessee is in accordance with Prudent Industry Practice and such
Lease Event of Default is waived by the Owner Lessor and the
Owner Participant) shall have occurred and be continuing; or

         (b) default of the Owner Lessor for 15 days in the payment when due any
(i) payment of principal of, premium (including, without limitation, Make-Whole
Premium), if any, or interest on, or any scheduled fees within fifteen days
after the same shall become due or (ii) other amounts due and payable by the
Owner Lessor under or with respect to, any Lessor Note and such failure shall
continue for thirty days after receipt by the Owner Lessor of written demand
therefore from the Security Agent; or

                                    46

         (c) any material representation or warranty made by the Owner
Participant or the Owner Lessor in this Lease Indenture or in any other
Operative Document to which it is a party shall prove to have been inaccurate
when made or deemed made in any material respect or by any OP Guarantor in
its OP Guaranty (provided the OP Guaranty shall not have been terminated or
released), as the case may be, and such misrepresentation or breach of
warranty remains material and shall not have been corrected within a period
of 30 days following written notice thereof being given to the Owner Lessor
and the Owner Participant or such OP Guarantor, as the case may be, by any
Noteholder (through the Lease Indenture Trustee); PROVIDED that, if such
misrepresentation or breach of warranty is capable of correction but cannot
with diligence be corrected within such 30-day period, such failure will not
constitute a Lease Indenture Event of Default so long as the party whose
representation or warranty was inaccurate promptly institutes corrective
action within such 30-day period and diligently pursues such corrective
action (but in no event shall the total period permitted to correct such
misrepresentation or breach of warranty extend beyond 120 days from the date
such notice was provided), or

         (d) any failure (i) by the Owner Lessor to observe, perform or
comply with the provisions of any material covenant or obligation of the
Owner Lessor contained in this Lease Indenture or in any Operative Document
to which it is a party (other than as provided in clause (a) above) in any
material respect or (ii) by the Owner Participant to observe or perform any
material covenant or obligation of the Owner Participant contained in any
Operative Document (other than the Tax Indemnity Agreement) to which it is a
party or (iii) by any OP Guarantor to observe or any material covenant or
obligation of such OP Guarantor contained in any OP Guaranty (provided the OP
Guaranty shall not have been terminated or released); and such covenant
remains material and such failure shall not have been cured within a period
of 30 days following written notice thereof being given to the Owner Lessor
and the Owner Participant, as the case may be, by any Noteholder (through the
Lease Indenture Trustee); PROVIDED that, if such failure is capable of cure
but cannot with diligence be cured within such 30-day period, such failure
will not constitute a Lease Indenture Event of Default so long as the party
failing to observe or perform such covenant promptly institutes corrective
action within such 30-day period and diligently pursues such corrective
action (but in no event shall the total period permitted to cure such failure
extend beyond 180 days from the date such notice was provided);

         (e) the Owner Participant, any OP Guarantor (provided the OP
Guaranty shall not have been terminated or released) or the Owner Lessor
shall (i) voluntarily commence any proceeding or file any petition seeking
relief under Bankruptcy Code or any other federal, state or foreign
bankruptcy, insolvency or similar law, (ii) consent to the institution of, or
fail to controvert in a timely and appropriate manner, any such proceeding or
the filing of any such petition, (iii) apply for or consent to the

appointment of a receiver, trustee, custodian, sequestrator or similar
official for the Owner Lessor, such OP Guarantor (provided the OP Guaranty
shall not have been terminated or released) the Owner Participant or any
substantial part of the property of any of the foregoing, (iv) file an answer
admitting the material allegations of a petition filed against it in any such
proceeding, (v) make a general assignment for the benefit of creditors, (vi)
become unable, admit in writing its inability or fail generally to pay its
debts as they become due, or (vii) take corporate action for the purpose of
effecting any of the foregoing; or

         (f) an involuntary proceeding is commenced or an involuntary
petition is filed in a court of competent jurisdiction seeking (i) relief in
respect of the Owner Participant, any OP Guarantor (provided the OP Guaranty
shall not have been terminated or released) or the Owner Lessor under
Bankruptcy Code or any other federal, state or foreign bankruptcy, insolvency
or similar law now or hereafter in effect, (ii) the appointment of a
receiver, Lease Indenture Trustee, custodian, sequestrator or similar
official for the Owner Participant, such OP Guarantor (provided the OP
Guaranty shall not have been terminated or released) or the Owner Lessor or
any substantial part of the property of the foregoing or (iii) the winding-up
or liquidation of the Owner Participant, such OP Guarantor (provided the OP
Guaranty shall not have been terminated or released) or the Owner Lessor and
such proceeding or petition continues undismissed for 60 days or an order or
decree approving or ordering any of the foregoing continues unstayed and in
effect for 60 days.

         (g) If Owner Lessor shall give any notice pursuant to 42 Pa.C.S.
Section 8143(c) or otherwise to terminate the operation of this Mortgage as
security for future advances or future obligations made or incurred after the
date the Lease Indenture Secured Parties receive such notice, or Owner Lessor
shall take any other similar action for the purpose of limiting or attempting
to limit the operation of this Mortgage as such security; or

SECTION 7.2                CERTAIN RIGHTS TO CURE

         In the event of any Lease Event of Default in the payment of any
installment of Basic Lease Rent or Supplemental Lease Rent (other than with
respect to Excepted Payments) due under the Facility Lease, the Owner Lessor
or the Owner Participant may, but shall not be obligated to, within ten
Business Days, (but with respect to Basic Lease Rent default in no event more
than 15 days after the related Rent Payment Date) after receipt by the Owner
Lessor and Owner Participant of written notice of


                                    48
<Page>

the occurrence of such Lease Default or Lease Event of Default, without the
consent or concurrence of the Security Agent, the Lease Indenture Trustee or
any Noteholder, pay, as provided in Section 2.11 hereof, for application in
accordance with Section 3.1 hereof, the principal of, interest on and other
amounts payable under or in respect of, the Lessor Notes as shall then be due
and payable on the Lessor Notes (without giving effect to any acceleration
pursuant to Section 7.3 hereof). If any other Lease Default or other Lease
Event of Default occurs and the Owner Lessor shall have been furnished (by or
for the account of the Owner Participant) with all funds necessary for
remedying such Lease Default or Lease Event of Default, the Owner Participant
may, within ten Business Days after the earlier of (a) receipt by the Owner
Participant of written notice of or (b) the Owner Participant acquiring
actual knowledge of the occurrence of such Lease Event of Default, without
the consent or concurrence of the Security Agent, the Lease Indenture Trustee
or any Noteholder, instruct the Owner Lessor to exercise the Owner Lessor's
rights under Section 20 of the Facility Lease to perform such obligation on
behalf of the Facility Lessee. Solely for the purpose of determining whether
there exists a Lease Indenture Event of Default, (a) any payment by the Owner
Participant or the Owner Lessor pursuant to, and in compliance with, the
first sentence of this Section 7.2 shall be deemed to remedy (for purposes of
this Lease Indenture) any Lease Default or Lease Event of Default in the
payment of installments of Basic Lease Rent theretofore due and payable and
to remedy any default by the Owner Lessor in the payment of any amount due
and payable under the Lessor Notes or hereunder, and (b) any performance by
the Owner Lessor of any obligation of the Facility Lessee under the Facility
Lease pursuant to, and in compliance with, the second sentence of this
Section 7.2 shall be deemed to remedy (for purposes of this Lease Indenture)
any Lease Default or Lease Event of Default to the same extent that like
performance by the Facility Lessee itself would have remedied such Lease
Event of Default (but any such payment or performance shall not relieve the
Facility Lessee of its duty to pay all Rent and perform all of its
obligations pursuant to the Facility Lease). If, on the basis specified in
the preceding sentence, such Lease Default or Lease Event of Default shall
have been remedied, then any determination that the Facility Lease, and any
declaration pursuant to this Lease Indenture that the Lessor Notes are due
and payable or that a Lease Indenture Default or Lease Indenture Event of
Default exists hereunder, based upon such Lease Default or Lease Event of
Default, shall be deemed to be rescinded, and the Owner Participant shall (to
the extent of any such payments made by or for the account of the Owner
Lessor) be subrogated to the rights of the Noteholders hereunder to receive
such payment of Rent from the Facility Lessee (and the payment of interest on
account of such Rent from the Facility Lessee being overdue), and shall be
entitled, so long as no other Lease Indenture Event of Default shall have
occurred or would result therefrom, to receive and retain such payment from
the Facility Lessee; provided, however, that the Owner Participant shall not,
so long as this Lease Indenture shall not have terminated,

                                    49

<Page>

otherwise attempt to recover any such amount paid by it or for its account on
behalf of the Facility Lessee pursuant to this Section 7.2 except by
demanding of the Facility Lessee payment of such amount or by commencing an
action at law and obtaining and enforcing a judgment against the Facility
Lessee for the payment of such amount or taking appropriate action in a
pending action at law against the Facility Lessee and the Owner Participant
will not obtain any Lien on any part of the Indenture Estate on account of
such payment nor will any claim of the Owner Participant against the Facility
Lessee or any other party for the repayment thereof impair the prior right
and security interest of the Lease Indenture Secured Parties in and to the
Indenture Estate, as the case may be; provided, further, however, that

                  (i) this Section 7.2 shall not apply with respect to any cure
         of any default in the payment of Basic Lease Rent if such cure shall
         have previously been effected with respect to (A) four (4) consecutive
         payments of Basic Lease Rent immediately preceding the date of such
         default, or (B) more than eight (8) payments of Basic Lease Rent;

                  (ii) neither the Owner Lessor nor the Owner Participant shall
         (without a Notice of Action) have the right to cure any Lease Event of
         Default except as specified in this Section 7.2; and

                  (iii) until the expiration of the period during which the
         Owner Lessor shall be entitled to exercise rights under the first and
         second sentence of this Section 7.2 with respect to any failure by the
         Facility Lessee referred to therein, neither the Lease Indenture
         Trustee and the Security Agent nor any Lease Indenture Secured Party
         shall take or commence any action it would otherwise be entitled to
         take or commence as a result of such failure by the Facility Lessee,
         whether under this Section 7 or Section 17 of the Facility Lease or
         otherwise.

SECTION 7.3                ACCELERATION

                  If any Lease Indenture Event of Default (other than a Lease
Indenture Event of Default specified in clause (e) or (f) of Section 7.1 hereof
with respect to the Owner Lessor) occurs and is continuing, the Security Agent
may, and upon written direction of the Noteholders of at least 33-1/3% (in the
case of any Lease Indenture Event of Default specified in clause (b) of Section
7.1 hereof) or 50% (in the case of any other Lease Indenture Event of Default)
in principal amount of the then outstanding Lessor Notes shall, declare, by
written notice to the Owner Lessor, all the Lessor Notes to be due and payable
immediately. Notwithstanding the foregoing, if a Lease Indenture Event of
Default specified in clause, (e) or (f) of Section 7.1 hereof occurs with
respect to the Owner Lessor, all outstanding Lessor Notes shall be due and
payable without further action or notice. Noteholders may


                                      50
<Page>

not enforce this Lease Indenture or the Lessor Notes except as provided in
this Lease Indenture. The Lease Indenture Trustee may withhold from
Noteholders a notice of any continuing Lease Indenture Default or Lease
Indenture Event of Default (except a Lease Indenture Default or Lease
Indenture Event of Default relating to the payment of principal or interest)
if it determines that withholding notice is in their best interest. The
Noteholders of 66 2/3% in aggregate principal amount of the then outstanding
Lessor Notes by notice to the Security Agent may on behalf of all Noteholders
rescind an acceleration and its consequences if the rescission would not
conflict with any judgment or decree and if all existing Lease Indenture
Events of Lease Indenture Default (except nonpayment of principal, interest
or premium that has become due solely because of the acceleration) have been
cured or waived.

                  The Noteholders of a majority (or 66 2/3% in case of a Lease
Indenture Event of Default triggered by the Lease Event of Lease Indenture
Default specified in clause (d)(i) of the Facility Lease, for non-compliance
with SECTION 6.1 of the Participation Agreement) in aggregate principal amount
of the Lessor Notes then outstanding by notice to the Lease Indenture Trustee
may on behalf of the Noteholders of all of the Lessor Notes waive any existing
Lease Indenture Lease Indenture Default or Lease Indenture Event of Default and
its consequences under this Lease Indenture except (i) a continuing Lease
Indenture Default or Lease Indenture Event of Default in the payment of
principal of, premium, if any, or interest on, the Lessor Notes (including in
connection with an offer to purchase) and (ii) a Lease Indenture Event of
Default specified in clause (e) or (f) of Section 7.1 hereof.

SECTION 7.4                OTHER REMEDIES

         (a) If a Lease Indenture Event of Default shall have occurred and so
long as the same shall be continuing unremedied the Security Agent may, if
not precluded by law or otherwise, exercise any or all of the rights and
powers and pursue any and all remedies available to collect the payment of
principal, premium, if any, or interest on the Lessor Notes including the
remedies pursuant to this Section 7.4 and shall have and may exercise all of
the rights and remedies of a secured party under any and all applicable law,
rule or regulation. It is understood and agreed that if a Lease Indenture
Event of Default has occurred and is continuing by virtue of one or more
Lease Events of Default the Security Agent shall not exercise foreclosure
remedies under this Lease Indenture without exercising material remedies
seeking to dispossess the Lessee under the Lease, unless exercising such
remedies under the Facility Lease shall be prohibited at the time by law,
governmental authority or court order, in which case the Security Agent shall
not exercise foreclosure remedies under the Lease Indenture until the
expiration of a period of one year from the commencement of such prohibition.
For the avoidance of doubt, it is expressly understood and agreed that the
above-described inability of the Security Agent to

                                      51
<Page>


exercise any right or remedy under the Facility Lease shall not prevent the
Security Agent from exercising any of its other rights, powers and remedies
under this Lease Indenture.

         (b) Both the Owner Lessor, the Lease Indenture Trustee and the
Security Agent irrevocably agree for the benefit of the Facility Lessee that
neither of them will exercise any remedies on account of a Lease Event of
Default resulting from a Rent Default Event other than (x) the Owner Lessor
may at any time a Rent Default Event has occurred and is continuing, exercise
the remedy set forth in Section 17.1(g) of the Facility Lease and (y) upon
the Rent Default Remedy Date, the Owner Lessor may declare the Facility Lease
in default and the Owner Lessor, or if the Lien of this Lease Indenture has
not terminated, the Security Agent may exercise all remedies. The Owner
Lessor and the Security Agent irrevocably agree that the Facility Lessee is a
third party beneficiary of the remedies set forth in SECTION 7.4 hereof.

SECTION 7.5                TAKING POSSESSION OF INDENTURE ESTATE

         (a) Subject to the rights of the Owner Lessor and the Owner
Participant under Sections 7.2 and 2.21 hereof, and unless a Lease Indenture
Event of Default shall have occurred and be continuing and the Lessor Notes
shall have been accelerated (and any such acceleration has not been
rescinded) pursuant to Section 7.3 hereof, upon a Notice of Action , the
Owner Lessor shall promptly execute and deliver or cause to be delivered to
the Security Agent such instruments and other documents as the Required Lease
Indenture Secured Parties may deem necessary or advisable to enable the
Security Agent at such time or times and place or places as the Security
Agent (acting upon a Notice of Action) may specify, to obtain possession of
all or any part of the Indenture Estate to which the Lease Indenture Secured
Parties shall at the time be entitled hereunder. If the Owner Lessor shall
for any reason fail to execute and deliver or cause to be delivered such
instruments and documents after such request by the Security Agent , the
Security Agent (acting upon a Notice of Action) may (i) obtain a judgment
conferring on the Security Agent the right to immediate possession and
requiring the Owner Lessor to execute and deliver or cause to be delivered
such instruments and documents to the Security Agent and the Owner Lessor
hereby specifically consents to the entry of such judgment to the fullest
extent it may lawfully do so, and (ii) to the extent permitted by law, pursue
all or part of such Indenture Estate, as applicable, wherever it may be
found, subject to Article XI of the Participation Agreement and Section 4.2
of the Facility Lease, if applicable. All expenses (including those of the
Security Agent) of obtaining such judgment or of pursuing, searching for and
taking such property shall, until paid, be secured by the Lien of this
Indenture.

                                      52
<Page>


         (b) Upon every such taking of possession in connection with a Lease
Event of Default, the Security Agent (acting upon a Notice of Action) may,
from time to time at the expense of the Indenture Estate, make all such
expenditures for maintenance, insurance, repairs, replacements, alterations,
additions and improvements to and of the Indenture Estate as the Required
Lease Indenture Secured Parties may deem proper. In each such case, the
Security Agent (acting upon a Notice of Action) or its designee shall have
the right to maintain, use, operate, store, lease, control or manage the
Indenture Estate and to carry on the business and to exercise all rights and
powers of the Owner Lessor relating to the Indenture Estate, as the Required
Lease Indenture Secured Parties shall deem best, including the right to enter
into any and all such agreements with respect to the maintenance, insurance,
use, operation, storage, leasing, control, management or disposition of the
Indenture Estate or any part thereof as the Required Lease Indenture Secured
Parties may determine; and the Security Agent shall be entitled to collect
and receive directly all tolls, rents (including Rent), revenues, issues,
income, products and profits constituting part of the Indenture Estate and
every part thereof, except Excepted Payments, without prejudice, however, to
the right of the Security Agent under any provision of this Lease Indenture
to collect and receive all cash held by, or required to be deposited with,
the Security Agent hereunder. Such tolls, rents (including Rent), revenues,
issues, income, products and profits shall be applied to pay the expenses of
use, operation, storage, subleasing, control, management or disposition of
the Indenture Estate and of conducting the business thereof, and of all
maintenance, repairs, replacements, alterations, additions and improvements,
and to make all payments which the Security Agent may be required or may
elect (acting upon a Notice of Action) to make, if any, for taxes,
assessments, insurance or other proper charges upon the Indenture Estate or
any part thereof (including the employment of engineers and accountants to
examine, inspect and make reports upon the properties and books and records
of the Owner Lessor), and all other payments which the Security Agent may be
required or authorized to make under any provision of this Lease Indenture,
as well as reasonable compensation for the services of the Lease Indenture
Trustee and the Security Agent, and of all Persons properly engaged and
employed by the Lease Indenture Trustee and the Security Agent.

SECTION 7.6                WAIVER OF PAST LEASE INDENTURE DEFAULTS

                  Upon any waiver of any existing Lease Indenture Default or
Lease Indenture Event of Default pursuant to the second paragraph of Section
7.3, such Lease Indenture Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured for every
purpose of this Lease Indenture; but no such waiver shall extend to any
subsequent or other Lease Indenture Default or impair any right consequent
thereon.

                                      53

SECTION 7.7                CONTROL BY MAJORITY

                  The Required Lease Indenture Secured Parties may direct the
time, method and place of conducting any proceeding for exercising any remedy
available to the Security Agent or exercising any trust or power conferred on
it. However, the Security Agent may refuse to follow any direction that
conflicts with law or this Lease Indenture or that the Security Agent
determines may be unduly prejudicial to the rights of other Noteholders or
the issuer of the Debt Service Reserve Letter of Credit or that may involve
the Security Agent in personal liability. The Security Agent e may take any
other action consistent with this Lease Indenture relating to any such
direction.

SECTION 7.8                [RESERVED]

SECTION 7.9                RIGHTS OF HOLDERS OF LESSOR NOTES TO RECEIVE PAYMENT

                  Notwithstanding any other provision of this Lease Indenture
but subject to Section 2.5, the right of any Noteholder, which is absolute
and unconditional, to receive payment of principal, premium, if any, and
interest on the Lessor Note, on or after the respective due dates expressed
in the Lessor Note (including in connection with an offer to purchase), or to
bring suit for the enforcement of any such payment on or after such
respective dates, or the obligation of the Owner Lessor, which is also
absolute and unconditional, to pay the principal of, premium, if any, and
interest on the Lessor Note to such Noteholder at the time and place set
forth in the Lessor Note, shall not be impaired or affected without the
consent of such Noteholder.

SECTION 7.10               COLLECTION SUIT BY LEASE INDENTURE TRUSTEE

                  If a Lease Indenture Event of Default specified in Section
6.1(a) occurs and is continuing, the Security Agent is authorized to recover
judgment in its own name and as Lease Indenture Trustee of an express trust
against the Owner Lessor for the whole amount of principal of, premium, if any,
and interest remaining unpaid on the Lessor Notes and interest on overdue
principal and, to the extent lawful, interest and such further amount as shall
be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, fees, expenses, disbursements and advances of the
Security Agent, its agents and counsel.

SECTION 7.11               [RESERVED]

                           UNDER THE FACILITY LEASE

                  Notwithstanding any other provision of any Operative
Document, so long as the Facility Lease shall not have been declared (or
deemed to have been declared) in default, the Security Agent shall not take
or cause to be taken any action contrary to the right of the Facility Lessee
under the Facility Lease, including its rights, as between the Facility
Lessee and the Owner Lessor, to quiet use and possession of the Undivided
Interest under the Facility Lease.

                   LEASE INDENTURE TRUSTEE AND SECURITY AGENT

SECTION 8.1                DUTIES OF LEASE INDENTURE TRUSTEE AND SECURITY AGENT

         (a) If a Lease Indenture Event of Default has occurred and is
continuing, the Security Agent and the Lease Indenture Trustee shall exercise
such of the rights and powers vested in it by this Lease Indenture, and use the
same degree of care and skill in its exercise as a prudent man would exercise or
use under the circumstances in the conduct of his own affairs.

         (b)      Except during the continuance of a Lease Indenture Event of
Default:

                  (i) the duties of each of the Lease Indenture Trustee and the
         Security Agent shall be determined solely by the express provisions of
         this Lease Indenture and the Lease Indenture Trustee and the Security
         Agent need perform only those duties that are specifically set forth in
         this Lease Indenture and no others, and no implied covenants or
         obligations shall be read into this Lease Indenture against the Lease
         Indenture Trustee or the Security Agent; and

                  (ii) in the absence of bad faith on its part, the Lease
         Indenture Trustee or the Security Agent may conclusively rely, as to
         the truth of the statements and the correctness of the opinions
         expressed therein, upon certificates or opinions furnished to the

         Lease Indenture Trustee or the Security Agent and conforming to the
         requirements of this Lease Indenture. However, the Lease Indenture
         Trustee and the Security Agent shall examine the certificates and
         opinions to determine whether or not they conform to the requirements
         of this Lease Indenture.

         (c) The Lease Indenture Trustee nor the Security Agent may not be
relieved from liabilities for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that:

<Page>


                  (i)  this paragraph does not limit the effect of paragraph
         (b) of this Section;

                  (ii) the Lease Indenture Trustee nor the Security Agent shall
         not be liable for any error of judgment made in good faith by a
         Responsible Officer, unless it is proved that the Lease Indenture
         Trustee or the Security Agent was negligent in ascertaining the
         pertinent facts; and

                  (iii) [the Lease Indenture Trustee and the Security Agent
         shall not be liable with respect to any action it takes or omits to
         take in good faith in accordance with a direction received by it
         pursuant to Section 7.7 hereof.]

         (d) Whether or not therein expressly so provided, every provision of
this Lease Indenture that in any way relates to the Lease Indenture Trustee or
the Security Agent is subject to paragraphs (a), (b), (c), (e) and (f) of this
Section.

         (e) No provision of this Lease Indenture shall require the Lease
Indenture Trustee nor the Security Agent to expend or risk its own funds or
incur any liability. The Lease Indenture Trustee and the Security Agent shall
be under no obligation to exercise any of its rights and powers under this
Lease Indenture at the request or direction of any Noteholders, unless such
Noteholder shall have offered and, if requested, provided to the Lease
Indenture Trustee security and indemnity satisfactory to it against any loss,

    SUPPLEMENTS AND AMENDMENTS TO THIS LEASE INDENTURE AND OTHER DOCUMENTS

SECTION 10.1      WITHOUT CONSENT OF NOTEHOLDERS OR REQUIRED NOTEHOLDERS.

                  Subject to the provisions of the Participation Agreement, at
any time and from time to time, the Owner Lessor (but only on the written
request of the Owner Participant) and the Lease Indenture Trustee may enter into
any indenture or indentures supplemental hereto or execute any amendment,
modification, supplement, waiver or consent with respect to any other Operative
Document, without the consent of the Noteholders or the Required Lease Indenture
Secured Parties for one or more of the following purposes:

                  (i) to correct, confirm or amplify the description of any
         property at any time subject to the Lien on the Indenture Estate or to
         convey, transfer, assign, mortgage or pledge any property or assets to
         the Security Agent as security for the Lessor Notes;

                  (ii) to evidence the succession of another corporation as
         Owner Manager or the appointment of a co-manager in accordance with
         the terms of the Lessor LLC Agreement;

                  (iii) to add to the covenants of the Owner Lessor for the
         benefit of the Lease Indenture Secured Parties such further covenants,
         restrictions, conditions or provisions as the Owner Lessor and the
         Security Agent shall consider to be for the protection of the
         Noteholders of any series, and to make the occurrence, or the
         occurrence and continuance, of a default in complying
         with any such additional covenant, restriction, condition or provision
         a Lease Indenture Event of Default permitting the enforcement of all or
         any of the several remedies provided in this Lease Indenture as herein
         set forth; in respect of any such additional covenant, restriction,
         condition or provision, such supplement may provide for a particular
         period of grace after default (which period may be shorter or longer
         than that allowed in the case of other defaults) or may provide for
         an immediate enforcement upon such a Lease


                                      66
<Page>

         Indenture Event of Default or may limit the remedies available to the
         Security Agent upon such a Lease Indenture Event of Default or may
         limit the right of the Required Lease Indenture Secured Parties to
         waive such a Lease Indenture Event of Default;

                  (iv) to cure any ambiguity or to correct or supplement any
         provision contained herein or in any supplement which may be defective
         or inconsistent with any other provision contained herein or in any
         supplement, or to add or modify such other provisions or agreements
         herein or in any other Operative Documents, in each case as the Owner
         Lessor may deem necessary or desirable, with respect to matters or
         questions arising under this Lease Indenture; provided that no such
         action shall, in the reasonable judgment of the Security Agent,
         materially adversely affect the interests of the Lease Indenture
         Secured Parties of any series;

                  (v) to provide for any evidence of the creation and issuance
         of any Subsequent Lessor Notes of any series pursuant to, and subject
         to the conditions of, Section 2.6 and to establish the form and terms
         of such Subsequent Lessor Notes;

                  (vi) to effect an assumption of the Lessor Notes, as permitted
         by Section 2.21; provided that the supplemental indenture entered into
         to effect such assumption shall contain all of the covenants applicable
         to the Facility Lessee contained in the Facility Lease and the
         Participation Agreement for the benefit of the Lease Indenture Trustee,
         the Security Agent or the Lease Indenture Secured Parties, such that
         the Facility Lessee's obligations contained therein, to the extent they
         are applicable, will continue to be in full force and effect in the
         event the Facility Lease is terminated;

                  (vii) to evidence and provide for the removal of the Lease
         Indenture Trustee or Security Agent or the acceptance of appointment
         hereunder by a successor Lease Indenture Trustee or Security Agent with
         respect to the Lessor Notes as provided in Section 8.8;

                  (viii) to grant or confer upon the Lease Indenture Trustee or
         the Security Agent for the benefit of the Lease Indenture Secured
         Parties any additional rights, remedies, powers, authority or security
         which may be lawfully granted or conferred upon the Lease Indenture
         Trustee or the Security Agent and which are not contrary to or
         inconsistent with this Lease Indenture;

                  (ix) subject to Section 10.2 with respect to the provisions of
         the Indenture Estate Documents referred to therein, to effect any other


                                      67
<Page>

         amendment, modification, supplement, waiver or consent with respect to
         any Indenture Estate Document; provided that no such action shall, in
         the judgment of the Security Agent, materially and adversely affect the
         interests of the Lease Indenture Secured Parties; PROVIDED, HOWEVER,
         that no such amendment, modification, supplement, waiver or consent
         contemplated by this Section 10.1 shall, without the consent of the
         Required Lease Indenture Secured Parties, modify the provisions of
         Sections [5.4, 5.12, 6.1, 6.2, 6.3, 6,4, 6.7 or 6.8] of the
         Participation Agreement or Sections [20.1, 23.4(b), 23.4(c) or 23.4(d)]
         of the Facility Lease (other than any amendment, modification,
         supplement, waiver or consent having no adverse effect on the interests
         of the Lease Indenture Secured Parties).

                  (x) The Security Agent and the Lease Indenture Trustee is
         hereby authorized to join with the Owner Lessor in the execution of any
         such supplement, to make any further appropriate agreements and
         stipulations which may be therein contained and to accept the
         conveyance, transfer, assignment, mortgage or pledge of any property or
         assets thereunder, but the Security Agent and the Lease Indenture
         Trustee shall not be obligated to enter into any such supplement which
         affects the Lease Indenture Trustee's or the Security Agent's own
         rights, duties or immunities under this Lease Indenture or otherwise.

SECTION 10.2      WITH CONSENT OF REQUIRED NOTEHOLDERS; LIMITATIONS.

                  Subject to the provisions of the Participation Agreement, at
any time and from time to time, (i) the Owner Lessor (but only on the written
request of the Owner Participant) and the Security Agent and the Lease Indenture
Trustee (but only if so directed upon a Notice of Action to the extent that the
same is not expressly permitted by Section 10.1), may execute a supplement or
amendment hereto for the purpose of adding provisions to, or changing or
eliminating provisions of, this Lease Indenture as specified in such request,

written amendment of or supplement to any Indenture Estate Document as may be
specified in such request and (iii) the Owner Lessor shall not revoke or
otherwise terminate the Lessor LLC Agreement or, if such amendment or supplement

any Lease Indenture Secured Parties, amend or supplement the Lessor LLC
Agreement; provided, however, that, without the consent of each Lease Indenture
Secured Party affected, except with respect to Excepted Payments, no such
amendment of or supplement to any Indenture Estate Document, and no waiver or


                                      68

         make any Lessor Note payable in money other than that stated on the
         Lessor Notes,

                  (iii) alter or modify the provisions of Section 3 hereof with
         respect to the manner of payment or the order of priorities in which
         distribution thereunder shall be made as between the Noteholders, the
         issuer of the Debt Service Reserve Letter of Credit and the Owner
         Lessor or the Owner Participant, or waive a Lease Indenture Event of
         Default in the payment of principal of, premium, if any, or interest on
         the Lessor Notes (except a rescission of acceleration of the Lessor
         Notes by the Noteholders of at least 66 2/3% in aggregate principal
         amount of then outstanding Lessor Notes and a waiver of the payment
         default that resulted from such acceleration),

                  (iv) reduce the amount (except as to any amount as shall be
         sufficient to pay the aggregate principal of, make-whole premium, if
         any, and interest on, all outstanding Lessor Notes) or extend the time

         Facility Lessee will be released from its obligation to pay Basic Lease
         Rent and Termination Value,

                  (vi) except in connection with Section 10.1(vi), release the

<Page>

         material portion of the Indenture Estate ranking equally or prior to

                       provisions.

SECTION 10.3               DOCUMENTS FURNISHED TO NOTEHOLDERS.

                  Promptly after the execution by the Owner Lessor, the Security
Agent or the Lease Indenture Trustee of any document entered into pursuant to
Sections 10.1 and 10.2, the Lease Indenture Trustee shall furnish a copy thereof
to the Noteholders but the failure of the Lease Indenture Trustee to deliver
such conformed copy, or the failure of the Noteholders to receive such conformed
copies, shall not impair or affect the validity of such document.

SECTION 10.4               LEASE INDENTURE TRUSTEE AND SECURITY AGENT PROTECTED.

                  Notwithstanding anything to the contrary contained herein, if,
in the opinion of the Lease Indenture Trustee or the Security Agent, any
document required to be executed by it pursuant to Sections 10.1 and 10.2
adversely affects any right, duty, immunity or indemnity of or in favor of the
Lease Indenture Trustee or the Security Agent under any Indenture Estate
Document or under any other Operative Document, the Lease Indenture Trustee or
the Security Agent may in its discretion decline to execute such document unless
the Person or Persons requesting any related action shall provide an indemnity
that is reasonably satisfactory to the Lease Indenture Trustee or the Security
Agent.

SECTION 10.5               REVOCATION AND EFFECT OF CONSENTS

                  Until an amendment, supplement or waiver becomes effective, a
consent to it by a Lease Indenture Secured Party is a continuing consent by the
Lease Indenture Secured Party, even if notation of the consent is not made on
any Lessor Note. However, any such Lease Indenture Secured Party may revoke the
consent if the Security Agent receives written notice of revocation before the
date the waiver, supplement or amendment becomes effective. An amendment,
supplement or waiver


                                      70
<Page>


becomes effective in accordance with its terms and thereafter binds every
Lease Indenture Secured Party.

SECTION 10.6               NOTATION ON OR EXCHANGE OF LESSOR NOTES

                  The Lease Indenture Trustee may place an appropriate notation
about an amendment, supplement or waiver on any Lessor Note thereafter
authenticated. The Owner Lessor in exchange for all Lessor Notes may issue and
the Lease Indenture Trustee shall, upon receipt of an Authentication Order,
authenticate new Lessor Notes that reflect the amendment, supplement or waiver.

                  Failure to make the appropriate notation or issue a new Lessor
Note shall not affect the validity and effect of such amendment, supplement or
waiver.

SECTION 10.7               LEASE INDENTURE TRUSTEE TO SIGN AMENDMENTS, ETC

                  The Lease Indenture Trustee and the Security Agent shall sign
any amended or supplemental Lease Indenture authorized pursuant to this Article
Nine if the amendment or supplement does not adversely affect the rights,
duties, liabilities or immunities of the Lease Indenture Trustee or the Security
Agent. The Owner Lessor may not sign an amendment or supplemental Lease
Indenture until the Board of Managers approves it. In executing any amended or
supplemental indenture, the Lease Indenture Trustee and the Security Agent shall
be entitled to receive and (subject to Section 8.1 hereof) shall be fully
protected in relying upon, in addition to the documents required by Section 12.4
hereof, an Officer's Certificate and an Opinion of Counsel stating that the
execution of such amended or supplemental indenture is authorized or permitted
by this Lease Indenture.

                                   ARTICLE XI
                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

SECTION 11.1               OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT
                           DEFEASANCE

                  The Owner Lessor may, at its option and at any time, elect to
have either Section 11.2 or 11.3 hereof be applied to all outstanding Lessor
Notes upon compliance with the conditions set forth below in this Article 11.

SECTION 11.2               LEGAL DEFEASANCE AND DISCHARGE

                  Upon the Owner Lessor's exercise under Section 11.1 hereof of
the option applicable to this Section 11.2, the Owner Lessor shall, subject to
the satisfaction of the conditions set forth in Section 11.4 hereof, be deemed
to have


                                       71
<Page>


been discharged from its obligations with respect to all outstanding Lessor
Notes on the date the conditions set forth below are satisfied (hereinafter,
"LEGAL DEFEASANCE"). For this purpose, Legal Defeasance means that the Owner
Lessor shall be deemed to have paid and discharged the entire Indebtedness
represented by the Debt Service Reserve Letter of Credit and by the
outstanding Lessor Notes, which shall thereafter be deemed to be
"OUTSTANDING" only for the purposes of Section 11.5 hereof and the other
Sections of this Lease Indenture referred to in (a) and (b) below, and to
have satisfied all its other obligations under such Lessor Notes and this
Lease Indenture (and the Lease Indenture Trustee or the Security Agent, as
applicable, on demand of and at the expense of the Owner Lessor, shall
execute proper instruments acknowledging the same), except for the following
provisions which shall survive until otherwise terminated or discharged
hereunder: (a) the rights of Noteholders of outstanding Lessor Notes to
receive solely from the trust fund described in Section 11.4 hereof, and as
more fully set forth in such Section, payments in respect of the principal
of, premium, if any, and interest on such Lessor Notes when such payments are
due, (b) the Owner Lessor's obligations with respect to such Lessor Notes
under Article 2 hereof, (c) the rights, powers, trusts, duties and immunities
of the Security Agent, the Lease Indenture Trustee and any Agent hereunder
and the Owner Lessor's obligations in connection therewith, including,
without limitation, Article 8 and Section 11.5 and 11.7 hereunder, and (d)
this Article 11. Subject to compliance with this Article 11, the Owner Lessor
may exercise its option under this Section 11.2 notwithstanding the prior
exercise of its option under Section 11.3 hereof.

SECTION 11.3               COVENANT DEFEASANCE

                  Upon the Owner Lessor's exercise under Section 11.1 hereof of
the option applicable to this Section 11.3, the Owner Lessor shall, subject to
the satisfaction of the conditions set forth in Section 11.4 hereof, be released
from its obligations under the material covenants contained herein with respect
to the outstanding Lessor Notes on and after the date the conditions set forth
in Section 11.4 are satisfied (hereinafter, "COVENANT DEFEASANCE"), and the
Lessor Notes shall thereafter be deemed not "outstanding" for the purposes of
any direction, waiver, consent or declaration or act of Noteholders (and the
consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "OUTSTANDING" for all other purposes hereunder (it being
understood that such Lessor Notes shall not be deemed outstanding for accounting
purposes). For this purpose, Covenant Defeasance means that, with respect to the
outstanding Lessor Notes or any outstanding amounts due under the Debt Service
Reserve Letter of Credit, the Owner Lessor may omit to comply with and shall
have no liability in respect of any term, condition or limitation set forth in
any such covenant, whether directly or indirectly, by reason of any reference
elsewhere herein to any such covenant or by reason of any reference in any such
covenant to any other provision herein or in any other


                                      72
<Page>


document and such omission to comply shall not constitute a Lease Indenture
Default or a Lease Indenture Event of Default under Section 7.1 hereof, but,
except as specified above, the remainder of this Lease Indenture and such
Lessor Notes shall be unaffected thereby. In addition, upon the Owner
Lessor's exercise under Section 11.1 hereof of the option applicable to this
Section 11.3 hereof, subject to the satisfaction of the conditions set forth
in Section 11.4 hereof, Section 7.1(a) hereof shall not constitute a Lease
Indenture Event of Default.

SECTION 11.4               CONDITIONS TO LEGAL OR COVENANT DEFEASANCE

                  The following shall be the conditions to the application of
either Section 11.2 or 11.3 hereof to the outstanding Lessor Notes or any
outstanding amounts due under the Debt Service Reserve Letter of Credit, as
applicable:

In order to exercise either Legal Defeasance or Covenant Defeasance:

         (a) the Owner Lessor must irrevocably deposit with the Security Agent
in the Security Agent's Account, in trust, for the benefit of the Noteholders
(or the issuer of the Debt Service Reserve Letter of Credit if applicable), cash
in United States dollars, non-callable Government Securities, or a combination
thereof, in such amounts as will be sufficient, in the opinion of a nationally
recognized firm of independent public accountants, to pay the principal of,
premium, if any, and interest on the outstanding Lessor Notes on the stated
maturity or on the applicable redemption date, as the case may be, and the Owner
Lessor must specify whether the Lessor Notes are being defeased to maturity or
to a particular redemption date and any amount outstanding under the Debt
Service Reserve Letter of Credit;

         (b) in the case of an election under Section 11.2 hereof, the Owner
Lessor shall have delivered to the Lease Indenture Trustee an Opinion of Counsel
in the United States reasonably acceptable to the Lease Indenture Trustee
confirming that (A) the Owner Lessor has received from, or there has been
published by, the Internal Revenue Service a ruling or (B) since the date of
this Lease Indenture, there has been a change in the applicable federal income
tax law, in either case to the effect that, and based thereon such Opinion of
Counsel shall confirm that, the Noteholders of the outstanding Lessor Notes will
not recognize income, gain or loss for federal income tax purposes as a result
of such Legal Defeasance and will be subject to federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if
such Legal Defeasance had not occurred;

         (c) in the case of an election under Section 11.3 hereof, the Owner
Lessor shall have delivered to the Lease Indenture Trustee an Opinion of Counsel
in the United States reasonably acceptable to the Lease Indenture Trustee
confirming that, subject to customary assumptions and exclusions, the
Noteholders of the outstanding


                                      73
<Page>


Lessor Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Covenant Defeasance and will be subject to
federal income tax on the same amounts, in the same manner and at the same
times as would have been the case if such Covenant Defeasance had not
occurred;

         (d) no Lease Indenture Default or Lease Indenture Event of Default
shall have occurred and be continuing on the date of such deposit (other than a
Lease Indenture Default or an Event of Lease Indenture Default resulting from
the borrowing of funds to be applied to such deposit) or insofar as Sections
7.1(e) or 7.1(f) hereof are concerned, at any time in the period ending on the
91st day after the date of deposit;

         (e) such Legal Defeasance or Covenant Defeasance shall not result in a
breach or violation of, or constitute a Lease Indenture Default under, any
material agreement or instrument (other than this Lease Indenture or any other
Financing Document) to which the Owner Lessor is a party or by which the Owner
Lessor is bound;

         (f) the Owner Lessor shall have delivered to the Security Agent an
Opinion of Counsel to the effect that (subject to customary qualifications and
assumptions) after the 91st day following the deposit, the trust funds will not
be subject to the effect of any applicable bankruptcy, insolvency,
reorganization or similar laws affecting creditors' rights generally;

         (g) the Owner Lessor shall have delivered to the Security Agent an
Officer's Certificate stating that the deposit was not made by the Owner Lessor
with the intent of preferring the Noteholders or the issuer of the Debt Service
Reserve Letter of Credit over any other creditors of the Owner Lessor or with
the intent of defeating, hindering, delaying or defrauding creditors of the
Owner Lessor or others; and

         (h) the Owner Lessor shall have delivered to the Lease Indenture
Trustee and the Security Agent an Officer's Certificate and an Opinion of
Counsel, each stating that, subject to customary assumptions and exclusions, all
conditions precedent provided for or relating to the Legal Defeasance or the
Covenant Defeasance have been complied with.

SECTION 11.5               DEPOSITED MONEY AND GOVERNMENT SECURITIES TO BE HELD
                           IN TRUST; OTHER MISCELLANEOUS PROVISIONS

in respect of the outstanding Lessor Notes or outstanding amounts due under
the Debt Service Reserve Letter of Credit shall be held in trust and applied
by the Security Agent, in accordance with the provisions of such Lessor Notes
and this Lease Indenture, to the payment, either directly or through any
Paying Agent [(including the Owner Lessor acting as Paying Agent)], to the
Noteholders of such Lessor Notes of all sums due and to become due thereon in
respect of principal, premium, if any, and interest, but such money need not
be segregated from other funds except to the extent required by law or the
issuer of the Debt Service Reserve Letter of Credit.

                  The Owner Lessor agrees to pay and indemnify the Lease
Indenture Trustee and the Security Agent against any tax, fee or other charge
imposed on or assessed against the cash or non-callable Government Securities
deposited pursuant to Section 11.4 hereof or the principal and interest received
in respect thereof other than any such tax, fee or other charge which by law is
for the account of the Noteholders of the outstanding Lessor Notes.

                  Anything in this Article 11 to the contrary notwithstanding,
the Lease Indenture Trustee or the Security Agent shall deliver or pay to the
Owner Lessor from time to time upon the request of the Owner Lessor any money or
non-callable Government Securities held by it as provided in Section 11.4 hereof
which, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the Lease
Indenture Trustee (which may be the opinion delivered under Section 11.4(a)
hereof), are in excess of the amount thereof that would then be required to be
deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

SECTION 11.6               REPAYMENT TO OWNER LESSOR

                  Any money deposited with the Security Agent or any Paying

principal of, premium, if any, or interest on any Lessor Note and remaining
unclaimed for two years after such principal, and premium, if any, or interest
has become due and payable shall be paid to the Owner Lessor on its request or
(if then held by the Owner Lessor) shall be discharged from such trust; and the
Noteholder of such Lessor Note shall thereafter, as a secured creditor, look
only to the Owner Lessor for payment thereof, and all liability of the Security
Agent or such Paying Agent with respect to such trust money, and all liability
of the Owner Lessor as trustee thereof, shall thereupon cease; PROVIDED,
HOWEVER, that the Security Agent or such Paying Agent, before being required
to make any such repayment, may at the expense of the Owner Lessor cause to be
published once, in The New York Times and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30


                                      75
<Page>


days from the date of such notification or publication, any unclaimed balance
of such money then remaining will be repaid to the Owner Lessor.

SECTION 11.7               REINSTATEMENT

                  If the Security Agent or Paying Agent is unable to apply any
United States dollars or non-callable Government Securities in accordance with
Section 11.2 or 11.3 hereof, as the case may be, by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, then the Owner Lessor's obligations
under this Lease Indenture and the Lessor Notes shall be revived and reinstated
as though no deposit had occurred pursuant to Section 11.2 or 11.3 hereof until
such time as the Security Agent or Paying Agent is permitted by such court or
governmental authority to apply all such money in accordance with Section 11.2
or 11.3 hereof, as the case may be; PROVIDED, HOWEVER, that, if the Owner Lessor
makes any payment of principal of, premium, if any, or interest on any Lessor
Note following the reinstatement of its obligations, the Owner Lessor shall be
subrogated to the rights of the Noteholders of such Lessor Notes to receive such
payment from the money held by the Security Agent or Paying Agent.

Affiliate of the Owner Lessor, as such, shall have any liability for any
obligations of the Owner Lessor under the Lessor Notes, this Lease Indenture or

their creation. Each Noteholder of Lessor Notes by accepting a Lessor Note
waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Lessor Notes. Such waiver may not be effective
to waive liabilities under the federal securities laws and it is the view of the
Commission that such a waiver is against public policy.

interpret this Lease Indenture.

                  All agreements of the Owner Lessor in this Lease Indenture and

Indenture Trustee and the Security Agent in this Lease Indenture shall bind its
successors.

SECTION 12.8               SEVERABILITY

                  In case any provision in this Lease Indenture or in the Lessor

entity acting as Owner Manager under the Lessor LLC Agreement) be personally
liable for or on account of any of the statements, representations,
warranties, covenants or obligations stated to be those of the Owner Lessor
or the Owner Manager hereunder, all such liability, if any, being expressly
waived by the parties hereto and any Person claiming by, through, or under
such party; PROVIDED, HOWEVER, that the Trust Company (or any such successor
Owner Manager) shall be personally liable hereunder for its own gross
negligence or willful misconduct or for its breach of its covenants,
representations and warranties contained herein, to the extent covenanted or
made in its individual capacity.

Indenture.

agrees that each payment of principal and interest or other amounts received
by it hereunder shall be applied, first, to the payment of interest on this

principal amount, as requested by the holder hereof surrendering the same.

                  Except as otherwise provided in Section 2.11 of the Lease
Indenture, prior to the due presentment for registration of transfer of this
Lessor Note, the Owner Lessor and the Lease Indenture Trustee shall deem and
treat the Person in whose name this Lessor Note is registered on the register
as the absolute owner and holder hereof for the purpose of receiving payment
of all amounts payable with respect to this Lessor Note and for all other
purposes whether or not this Lessor Note is overdue, and neither the Owner
Lessor nor any holder hereof shall be affected by any notice to the contrary.
All payments made on this Lessor Note in accordance with the provisions of

and neither the Lease Indenture Trustee nor the Owner Lessor shall have any
liability in respect of such payment.

                  This Lessor Note is subject to redemption solely as
required by Sections 4.7 and 4.8 of the Lease Indenture, to purchase by the
Owner Lessor or the Owner Participant as provided in Section ___ of the
Indenture and to assumption by the Facility Lessee in accordance with Section
2.21 of the Lease Indenture. If at any time a Lease Indenture Event of
Default shall have occurred and be continuing, this Lessor Note may, subject
to certain rights of the Owner Lessor and Owner Participant contained or
referred to in the Lease Indenture, be declared, and under certain
circumstances shall automatically be deemed to be declared, due and payable,
all upon the conditions, in the manner and with the effect provided in the
Lease Indenture.

                  By its acceptance hereof, the holder of this Lessor Note
agrees that the Owner Manager is executing this Lessor Note on behalf of the
Owner Lessor solely in its capacity as Owner Manager under the Lessor LLC
Agreement and not in its individual capacity and in no case shall the Trust
Company (or any entity acting as Owner Manager under the Lessor LLC
Agreement) be personally liable in respect of the obligations stated to be
those of the Owner Lessor or the Owner Participant hereunder.

                  In circumstances set forth in Section 2.21 of the
Indenture, the obligations of the Owner Lessor under this Lessor Note may,
subject to the conditions set forth in Section 2.21 of the Lease Indenture,
be assumed in whole by the Facility Lessee in accordance with Section 2.21 of
the Lease Indenture, in which case the Owner Lessor shall be released and
discharged from all such obligations. In connection with such an assumption,
the holder of this Lessor Note may be required to exchange this Lessor Note
for a new Lessor Note evidencing such assumption.

                  THIS LESSOR NOTE SHALL IN ALL RESPECTS BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE, WITH THE LAWS OF THE STATE OF NEW YORK.
