Liens other than Permitted Liens without any other liability or cost to the
Ground Sublessee, and (b) upon the request of the Ground Sublessor, execute,
acknowledge, and deliver a release (or termination) of the Ground Interest or
such portion thereof which release (or termination) shall be prepared by the
Ground Sublessor at the expense of, and in a form reasonably satisfactory to,

Interest relating to the Unit that is no longer subject to the Facility Lease,
as determined by the Ground Sublessor and the Ground Sublessee, each acting
reasonably (such portion, the "Non-Subleased Portion").  Any such termination

shall execute, acknowledge, and deliver a termination of the Site Sublease with
respect to the Ground Interest or such portion thereof, which termination shall
be prepared by the Ground Sublessee at its expense and in a form reasonably
satisfactory to the Ground Sublessor to be duly recorded at the Ground
Sublessee's expense with the Orange County Clerks Office, Orange County, New
York.

     Section 2.6.   Nonterminability.  Subject to Section 2.5 hereof, the Site
Sublease Term shall not be terminated nor shall any of the rights granted or
conveyed hereunder to the Ground Sublessee be extinguished, diminished, lost or
otherwise impaired, in whole or in part, by any circumstance of any character or
for any reason whatsoever, including any of the following: (a) any loss or
destruction of, or damage to, the Facility, any Component thereof or

property in which an interest is intended to be granted or conveyed by this Site
Sublease, (e) the insolvency, bankruptcy, reorganization or similar proceedings
by or against the Ground Sublessor, the Ground Sublessee or any other Person,

SECTION 3.  RENT FOR THE SUBLEASE OF GROUND INTEREST

     Section 3.1.   Rent. The Ground Sublessee agrees to pay as rent for the
sublease of the Ground Interest to the Ground Sublessor pursuant to this Site
Sublease the amount of rent payable under the Site Lease for the corresponding
period, which rent shall be paid on the dates set forth in the Site Lease,
except that if the Facility Lease is terminated with respect to a Unit pursuant
to Section 10 thereof and the Owner Lessor does not tender such Unit to the
Facility Lessee such that in accordance with Section 2.5 the Non-Subleased
Portion is leased to the Ground Sublessor pursuant to Section 2.1 of the Site
Lease but is not subleased to the Ground Sublessee pursuant to Section 2.1, rent
payable during the remainder of the Site Sublease Term for the Ground Interest
shall be the amount specified above multiplied by the Unit Percentage for the
Unit that continues to be subject to the Facility Lease.  Rent shall be prorated
for any partial period on the basis of the actual number of days in such period.

     Section 3.2.   Payment. The Ground Sublessor and the Ground Sublessee agree
that, during the Site Sublease Term, each payment of rent by the Ground
Sublessor, as lessee, for the lease of the Ground Interest pursuant to Section
3.1 of the Site Lease and each payment of rent by the Ground Sublessee for the
sublease of the Ground Interest pursuant to Section 3.1 hereof shall be offset,
and no amounts shall be payable by the Ground Sublessor or the Ground Sublessee
in respect thereof, except that if the Facility Lease is terminated with respect
to a Unit pursuant to Section 10 thereof and the Owner Lessor does not tender
such Unit to the Facility Lessee such that the Non-Subleased Portion is leased
to the Ground Sublessor pursuant to Section 2.1 of the Site Lease but is not
subleased to the Ground Sublessee pursuant to Section 2.1, the  portion of the
rent under the Site Lease equal to the Unit Percentage of the Unit that is no
longer subject to the Facility Lease shall not be offset but shall be paid by
the Ground Sublessor to the Ground Sublessee under the Site Lease.

SECTION 4.  QUIET ENJOYMENT IN FAVOR OF THE GROUND SUBLESSEE

     Section 4.1.   Ground Sublessee's Right of Quiet Enjoyment. The Ground
Sublessor warrants that it has full right and authority to sublease the Ground
Interest to the Ground Sublessee pursuant to the terms of this Site Sublease and
agrees that, notwithstanding any provision of any other Operative Document, so
long as the Site Sublease Term has not been terminated pursuant to the express
provisions of Section 2.5 hereof, neither the Ground Sublessor nor any Person
claiming by, through or under the Ground Sublessor shall, through its or their
own actions or inactions, interfere with or interrupt the quiet enjoyment of the
use, operation and possession by the Ground Sublessee of the subleasehold
interest in the Ground Interest subject to the terms hereof; provided, that the
Ground Sublessor's covenant does not relate to actions of the Lease Indenture
Trustee.

     Section 4.2.   Conveyances Pursuant to the Site Lease. Sales, grants of
leases or easements and conveyances of portions of the Facility Site, rights of
way, easements or leasehold interests made or reserved by the Ground Sublessee
in accordance with Sections 4.2 or 4.3 of the Site Lease shall not constitute a
breach of the Ground Sublessee's right of quiet enjoyment under this Site
Sublease. In light of the nature of the Released Property to be sold, granted,
released, leased or conveyed, either (x) this Site Sublease shall be subject to
the interest created in connection with the Released Property or (y) the
Released Property shall no longer be a part of

                                       5
<PAGE>

the Ground Interest and shall automatically be deemed to be subject to or
released from the effect of this Site Sublease and any Lien on the Ground
Interest or otherwise under this Site Sublease, in either case, without the
necessity of the execution, delivery or recording of any further instrument
whatsoever. Any grant, sublease, assignment, encumbrance or conveyance by the
Ground Sublessor of its rights, title or interest under this Site Sublease shall
not constitute a breach of the Ground Sublessee's right of quiet enjoyment under
this Site Sublease; provided that such grant, sublease, assignment, encumbrance
or conveyance expressly provides that the Ground Sublessor's interest under this
Site Sublease is subject to the Ground Sublessee's release rights set forth in
Section 4.2 and 4.3 of the Site Lease, that any Released Property shall
automatically be deemed to be released from the effect of any such grant,
sublease, assignment, encumbrance or conveyance without the necessity of the
execution, delivery or recording of any further instrument whatsoever, and that
the other party to such grant, sublease, assignment, encumbrance or conveyance
shall, at the request and expense of the Ground Sublessee, execute and deliver
such documents and instruments as may be reasonably requested by the Ground
Sublessee to evidence the foregoing.

SECTION 5.  USE OF GROUND INTEREST

     Section 5.1.   Use. The Ground Sublessee's rights hereunder to use the
Ground Interest during the Site Sublease Term shall be limited to the right of
the Ground Sublessee to use (a) the Facility Site in connection with the use,
operation, maintenance, repair, upgrade, improvement, alteration, removal,
restoration and modification of the Facility in accordance with the terms of the
Operative Documents, which shall include the right to construct, install,
operate, use, repair and relocate facilities, equipment and/or structures on or
under the Facility Site, including buildings, roads, paths, walkways, sanitary
sewers, storm drains, water, gas and/or oil mains, waste disposal systems,
electric power lines, transmission lines, telephone, television and
telecommunication lines, fire protection systems, safety sensor and monitoring
systems and utility lines and systems, all as are reasonably necessary or
advisable for the commercial operation of the Facility; (b) the Cross Easement
Rights in connection with the use and operation of the Facility; (c) the
Retained Power and Control Lines for the continued transmitting and/or
distributing of electrical and related service to and from the Facility; (d) the
Dock Facilities and the Railroad Tracks for the delivery and unloading of coal,
oil, other commodities and equipment for the Facility and, in the case of the
Railroad Tracks the temporary storage of railcars used or to be used for
delivery of such commodities and equipment, and (e) the Retained Oil Pipeline
for delivery of oil to the Facility; provided, that the Ground Sublessee may not
relocate or expand any easement or any facility relating thereto except as
expressly provided in Section 2.1(a) or as permitted under the Site Lease.

     Section 5.2.   Compliance with Environmental Laws. The Ground Sublessee
will comply with all Environmental Laws of any Governmental Entity having
jurisdiction as the same pertain to the Facility Site, unless such noncompliance
(A) is not reasonably likely to have a Material Adverse Effect or involve any
danger of foreclosure, sale, forfeiture or loss of, or imposition of a Lien on,
the Facility or the impairment of the use, operation or maintenance of the
Facility in any material respect, and (B) could not result in any criminal
liability being incurred by, or could not reasonably be expected to have any
material adverse effect on the interests of, the Owner Participant or the Ground
Sublessor.

     The Ground Sublessee expressly agrees that the Ground Sublessee shall not
transfer the Ground Interest except as part of the Ground Sublessee's transfer
of the Facility Lessee's Interest pursuant to the Operative Documents.  The
Ground Sublessor acknowledges that the Ground Sublessee shall have the right to
sublease or assign the Ground Interest to a Person that is a sublessee or
assignee of the Facility in accordance with Section 19 of the Facility Lease or
Section 13.2 of the Participation Agreement.

SECTION 7.   LIENS

     The Ground Sublessee agrees that it will not, directly or indirectly,
create, incur, assume or suffer to exist any Lien on or with respect to the
Ground Interest or the Facility Site other than Permitted Liens, and the Ground
Sublessee shall promptly notify the Ground Sublessor of the imposition of any
such Lien of which the Ground Sublessee is aware and shall promptly, at its own
expense, take such action as may be necessary to fully discharge or release any
such Lien.

SECTION 8.   SEVERANCE

     The Facility, Components, Replacement Components, all equipment at any time
acquired by the Ground Sublessor and located on the Facility Site and each part
thereof have been severed from the Facility Site and from title thereto, shall
be considered as personal property, and even though attached or affixed to or
installed upon the Facility Site, as the case may be, shall not be considered to
become fixtures or a part of the Facility Site. The Ground Sublessor waives any
rights it may have under the laws of the State of New York or otherwise to any
Lien upon, or right of attachment (other than a leasehold interest in or right
to use, as the case may be) with respect to, the Retained Power and Control
Lines, the Retained Oil Pipelines, the Railroad Tracks or the Dock Facilities or
any part thereof.

SECTION 9.   NONMERGER

     The reversionary interest of the Ground Sublessee in the Ground Interest
shall not merge into any interest in the Ground Interest conveyed by this Site
Sublease even if such reversionary interest and such interest leased are at any
time vested in or held directly or indirectly by the same Person, but this Site
Sublease shall nonetheless remain in full force and effect in accordance with
its terms notwithstanding such vesting or holding unless and until the Person
holding such interests shall execute an instrument effecting such merger and
shall duly record such instrument.  No such instrument of merger shall be
executed and recorded unless and until the Lien of the Lease Indenture on the
Indenture Estate has been discharged in accordance with the terms thereof.

SECTION 10.  SECURITY FOR OWNER LESSOR'S OBLIGATION UNDER
             LESSOR NOTE

     In order to secure the Notes, the Ground Sublessor will, by the Lease
Indenture, assign and grant a Lien to the Lease Indenture Trustee in and to all
of the Ground Sublessor's right, title and interest in, to and under the Site
Lease, this Site Sublease and the Ground Interest (other than Excepted Payments
and Excepted Rights).  The Ground Sublessee hereby consents to such

                                       7
<PAGE>

assignment and creation of such Lien and any sale arising from or in connection
with the exercise of remedies and acknowledges receipt of copies of the Lease
Indenture, it being understood that such consent shall not affect any
requirement or absence of any requirement for any consent under any other
circumstances. Unless and until the Ground Sublessee shall have received written
notice from the Lease Indenture Trustee that the Lien of the Lease Indenture has
been fully released, the Lease Indenture Trustee under the Lease Indenture shall
have the rights of the Ground Sublessor under this Site Sublease to the extent
set forth in and subject in each case to the exceptions set forth in the Lease
Indenture.

SECTION 11.  INSPECTION

     During the Site Sublease Term, each of the Owner Participant, the Ground
Sublessor, and, so long as the Lien of the Lease Indenture shall not have been
terminated or discharged, the Lease Indenture Trustee and the Pass Through
Trustees and the respective representatives of such Persons may, during normal
business hours, on reasonable notice to the Ground Sublessee and at their own
risk and expense (except, at the expense but not risk, of the Ground Sublessee
when a Significant Lease Default or a Lease Event of Default has occurred and is
continuing), inspect the Facility Site, and the records with respect to the
operations and maintenance thereof, in the Ground Sublessee's custody or to
which the Ground Sublessee has Access; provided, however, that so long as no
Significant Lease Default or Lease Event of Default shall have occurred and be
continuing, each such Person shall only be entitled to make one inspection in
any 12-month period, provided, further, however, that any such Person may make
more than one inspection during the last 18 months of the Site Sublease Term
unless the Ground Sublessee has exercised its option under Section 15 of the
Facility Lease to renew the Facility Lease and thereby extending the Site
Sublease Term beyond such 18-month period.  Any such inspection will not
unreasonably interfere with the operation or maintenance of the Facility, or the
conduct by the Ground Sublessee of its business and will be in accordance with
the Ground Sublessee's safety and insurance programs.  In no event shall any of
the Ground Sublessor, the Owner Participant, the Lease Indenture Trustee or the
Pass Through Trustee have any duty or obligation to make any such inspection and
such Persons shall not incur any liability or obligation by reason of not making
any such inspection.
