         NOW, THEREFORE, in consideration of the foregoing premises, the mutual
agreements herein contained, and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

                                     NOTICE

The Facility Lessee acknowledges the following with respect to disposal of
materials on the Facility Site:

o        Asbestos insulation and other asbestos containing materials have been
         disposed in the active Stage II on-site ash disposal landfill (Parcel
         A) (pursuant to PaDEP solid waste permit #300876). Additional
         information regarding the quantities and locations within the landfill
         of such disposal is in the possession of the PaDEP.

o        Wastewater treatment sludges which may contain hazardous substances
         were removed during cleaning of the various on-site wastewater
         impoundments and disposed of in either Stage I or Stage II of the
         on-site ash disposal landfill (Parcel A) (PaDEP solid waste permit
         #300876) via blending with fly ash and bottom ash, prior to final
         placement and compaction. Filling of the Stage I portion of the
         landfill has been completed. Similar materials generated at the Seward
         Generating Station have been land-filled in the Stage II on-site ash
         disposal landfill. Concentrations of metals have been detected in the
         soils and groundwater in this area.

o        Bottom Ash which may contain hazardous substances has been utilized at
         the site for the construction of roadways and structural fills in low
         lying areas. These areas include, but are not limited to, the outside
         storage area west of the Unit #2 crane bay (Parcel B), the area around
         the ash haul contractor buildings (Parcel C), the outside storage area
         south of the coal yard office and rotary car dumper (Parcel D), the
         outside storage and parking area southwest of the coal pile and inside
         the drainage ditch (Parcel E), the area north of the intake clarifier
         (Parcel F), and the truck parking area west of the main sub yard
         (Parcel G).

o        Four unlined active ash ponds (also known as station filter ponds or
         wastewater storage impoundments) (Parcel H) have been used for the
         storage of high and low pH waste waters prior to final treatment, and
         as a collection point for various chemical spills of sulfuric acids and
         caustic soda (all of the spills were subsequently remediated).

o        The electric generation and transmission equipment at the site has, at
         times, included equipment with dielectric fluids which contained
         polychlorinated biphenyls (PCBs). Spillage of these fluids may have
         occurred in these areas (Parcels T-Sub, T-1 and T-2). Soil sampling in
         the substation area (Parcel T-Sub) did not detect concentrations of
         PCBs.

                            Conemaugh Facility Lease
                                        2
<PAGE>   7

o        Spills of used oils have occurred at or near the mobile and stationary
         operating equipment and storage tanks associated with the electric
         generating facility, including, but not limited to, air compressors,
         fans, mills, and seal oil systems. The spills were remediated utilizing
         one or more of the following collection methods: oil absorbent
         materials, bulk collection of free oils, or mechanical removal of
         residual materials including soils and water. Residual materials were
         generally disposed through either off-site disposal services or
         incineration in the utility boilers. The Phase I Environmental
         Assessment specifically noted evidence of staining on the concrete pad
         in the Used Oil Storage area near the aboveground waste oil storage
         tanks.

o        Cooling tower waters which may have contained hazardous substances,
         including sodium hypochlorite and bromide, were discharged to the
         Cooling Tower Desilting Basin.

o        On February 6, 1978, a bushing failure on the 1C Main Transformer
         caused 11,250 gallons of transformer oil containing concentrations of
         approximately 1 part per million of PCBs to be spilled into the gravel
         pit below the transformer (Parcel T-2). Residual materials were removed
         and disposed off-site.

o        On June 18, 1986, 8000 gallons of transformer oil containing
         concentrations of approximately .5 parts per million of PCBs was
         spilled in Parcel T-2 as a result of a fire and subsequent rupture of
         the "C" Main Transformer (EPA reference #3HW22). The bulk of the
         spilled oil was captured in emergency containment tanks, but some
         material was discharged into the Conemaugh River. Oil booms were
         utilized to contain and remove free liquids and affected soils were
         excavated and disposed off-site.

o        In April and October of 1991, spills of electro hydraulic control (EHC)
         fluid in the station basement area resulted in small amounts of the
         material reaching the active ash ponds. (Parcel H). EHC fluid is
         heavier than water and should have been integrated into the ponds'
         sludge materials that were subsequently disposed in the Stage II
         portion of the on-site ash disposal landfill (Parcel A).

o        Fly ash and bottom ash which may contain hazardous substances were
         disposed of in impoundments, now closed. (Parcel J).

o        In June of 1996, approximately 7300 gallons of Sodium Hypochlorite and
         1000 gallons of Sodium Bromide were spilled in the vicinity of the Unit
         #1 Cooling Tower Bleach pump (Parcel K). Affected soils were removed
         and disposed of in the Stage II portion of the on-site ash disposal
         landfill.

o        In August of 1999, approximately 20 gallons of Sodium Hypochlorite and
         1000 gallons of Sodium Bromide were spilled in the vicinity near the #
         2 cooling tower bleach tank (Parcel K). Liquid spilled materials were
         recovered and placed in the cooling tower system. Visually contaminated
         soils were excavated for off site disposal. Details of the spill were
         reported to the PADEP in a Notification of Reportable Release Form
         submitted on August 26, 1999.

<PAGE>   8

o        In June of 2000, approximately 25 gallons of biocide were spilled in
         the vicinity of the # 1 cooling tower (Parcel K). Liquid spilled
         materials were recovered and placed in the cooling tower system.
         Visually contaminated soils were excavated for off site disposal.
         Details of the spill were reported to the PADEP in a Notification of
         Reportable Release Form submitted on June 5, 2000.

o        In June of 2000, less than 50 gallons of Sodium Hypochlorite were
         spilled near the # 1 cooling tower bleach tank (Parcel K). Liquid
         spilled materials were recovered and placed in the cooling tower
         system. Details of the spill were reported to the PADEP in a
         Notification of Reportable Release Form submitted on July 6, 2000.

o        Groundwater sampling in the area of the coal pile runoff ditch detected
         concentrations of metals and sulfates.

o        Herbicides have been used to control the growth of vegetation across
         the site at various times including, but not limited to, the areas
         within the main fuel oil storage tanks' spill containment in the Main
         Oil Tank area and the substation area (Parcel T-Sub) and underneath the
         transmission lines.

3.3(a), the Allocated Rent calculated pursuant to this Section 3.3(b) shall
represent and be the amount of Periodic Lease Rent for which the Facility Lessee
becomes liable on account of the use of the Facility Interest for each calendar
year included in whole or in part of the Lease Term.

                  (c) The allocation of Periodic Lease Rent to each Rent Payment
Period as provided in Section 3.3(b) constitutes a specific allocation of fixed
rent within the meaning of Treasury Regulation 1.467-1(c)(2)(ii) with the effect
that the Owner Lessor and the Facility Lessee, on any federal income tax returns
filed by them (or on any return on which their income

                            Conemaugh Facility Lease
                                       5

is included), shall accrue the amounts of rental income and rental expense,
respectively, set forth for each Rent Payment Period set forth on Schedule 1-B.
The difference between the cumulative amount of Periodic Lease Rent paid by the
Facility Lessee (as set forth in paragraph (a) of this Section 3.3) and the
cumulative amount of Periodic Lease Rent allocated (as set forth in paragraph
(b) of this Section 3.3), shall be considered the amount of the "Section 467
Loan" as set forth on Schedule 1-C hereof. If the Section 467 Loan balance is
positive, such amount ("Lessor Section 467 Loan Balance") represents a loan from
the Facility Lessee to the Owner Lessor; if the Section 467 Loan Balance is
negative, such amount ("Lessee Section 467 Loan Balance") represents a loan from
the Owner Lessor to the Facility Lessee. If there shall be a Lessor Section 467
Loan Balance, the Owner Lessor shall deduct interest expense and the Facility
Lessee shall accrue interest income in an amount equal to the amount set forth
for such Rent Payment Period on Schedule 1-C ("Lessor Section 467 Interest"). If
there shall be a Lessee Section 467 Loan Balance, the Owner Lessor shall accrue
interest income and the Facility Lessor shall deduct interest expense in an
amount equal to the amount set forth for such Rent Payment Period on Schedule
1-C ("Lessee Section 467 Interest"). In no event shall any principal or interest
on any Section 467 Loan be separately payable; all Section 467 Loan principal
and interest is already included as part of Periodic Lease Rent and Termination
Value and is payable as a portion of the amounts set forth under the heading
"Periodic Lease Rent" on Schedule 1-A or under the heading "Termination Value"
on Schedule 2.

         Section 3.4 Supplemental Lease Rent. The Facility Lessee also agrees to
pay to the Owner Lessor, or to any other Person entitled thereto as expressly
provided herein or in any other Operative Document, as appropriate, any and all
Supplemental Lease Rent (including any Make Whole Premium or Change of Control
Premium, if any), promptly as the same shall become due and owing, or where no
due date is specified, promptly after demand by the Person entitled thereto, and
in the event of any failure on the part of the Facility Lessee to pay any
Supplemental Lease Rent, the Owner Lessor shall have all rights, powers and
remedies provided for herein or by law or equity or otherwise for the failure to
pay Periodic Lease Rent. The Facility Lessee will also pay as Supplemental Lease
Rent, to the extent permitted by Applicable Law, an amount equal to interest at
the applicable Overdue Rate on any part of any payment of Periodic Lease Rent
not paid when due for any period for which the same shall be overdue and on any
Supplemental Lease Rent not paid when due (whether on demand or otherwise) for
the period from such due date until the same shall be paid. The Facility Lessee
also agrees to pay as Supplemental Lease Rent an amount equal to any amount of
Make Whole Premium and Change of Control Premium required to be paid pursuant to
the Lease Indenture or any Note. All Supplemental Lease Rent to be paid pursuant
to this Section 3.4 shall be payable in the manner set forth in Section 3.6.

         Section 3.5 Adjustment of Lease Schedules.

                  (a) Periodic Lease Rent, Allocated Rent, Lessor Section 467
Loan Balance, Lessee Section 467 Loan Balance, Lessor Section 467 Interest,
Lessee Section 467 Interest and Termination Value (collectively, the "Adjustment
Items") shall be adjusted, either upward or downward, to reflect: (i) the effect
of any refunding or refinancing of the Lease Debt and Notes (including without
limitation, the principal amount, amortization and interest rates) issued
pursuant to Section 2.12 of the Lease Indenture in connection with a refinancing
of the Notes pursuant to Section 12.2 of the Participation Agreement; (ii) the
financing of Modifications to

                            Conemaugh Facility Lease
                                       6
<PAGE>   11

the Facility pursuant to Section 12.1 of the Participation Agreement (including
without limitation the issuance of Additional Lessor Notes pursuant to Section
2.12 of the Lease Indenture in connection therewith) or (iii) the correction of
any manifest error in the mathematical computation of the Adjustment Items.

                  (b) In the event the Registration Statement is not effective
or the Exchange Offer has not been consummated within 270 days of the Initial
Purchaser's request therefor (collectively, "Registration Delay"), the Owner
Lessor and the Facility Lessee will institute an alternative rent schedule (the
"Alternative Rent Schedule") to replace Schedules 1-A, 1-B and 1-C attached
hereto and an alternative termination value schedule (the "Alternative
Termination Value Schedule") to replace Schedule 2 attached hereto. The
Alternative Rent Schedule will require amounts of Periodic Lease Rent during the
Basic Lease Term ("Alternative Rent") to be paid that equal the sum of the
Periodic Lease Rent that would have been paid absent a Registration Delay and an
amount equal to the increased amounts paid pursuant to the Notes because of the
Registration Delay ("Additional Amount"). The Alternative Termination Value
Schedule will reflect the increase on any Termination Date of such Additional
Amount. The Alternative Rent Schedule will allocate the Additional Amount over
the Basic Lease Term in accordance with the rules of Section 467 of the Code
then in effect and in a manner that preserves the Owner Participant's Expected
Return. At the commencement of any Registration Delay, the Alternative Rent
Schedule and Alternative Termination Value Schedule will be based on the
assumption that the Additional Amount applies for the term of the Notes. In the
event the Additional Amount terminates prior to the term of the Notes, such
schedules will be revised to reflect the actual amounts of Additional Amount
paid. It is the intent of the Owner Lessor and the Facility Lessee that the
options set forth in this Section 3.5(b) constitute alternative rent schedules
as contemplated under Treasury Regulation 1.467-1(h)(3)(v).

                  (c) Any adjustments pursuant to this Section 3.5 shall be
calculated (i) first, to maintain the Owner Participant's Expected Return, and
(ii) second, at the option of the Facility Lessee, (A) to minimize the average
annual Periodic Lease Rent over the Basic Lease Term for the Facility Lessee's
GAAP accounting purposes, (B) to minimize to the extent possible, the net
present value, discounted at the Discount Rate, compounded on a semi-annual
basis to the date of the termination, of Periodic Lease Rent and/or (C) to
maintain operating lease treatment for the Facility Lessee; provided that no
such adjustment shall require the Owner Participant to record a loss as of the
date such adjustment is made or shall change the Owner Participant's book
earnings for the year in which such adjustment is made and each of the
succeeding four years by more than plus or minus 5% without the consent of the
Owner Participant.

                  (d) Anything herein or in any other Operative Document to the
contrary notwithstanding, Periodic Lease Rent payable on any Rent Payment Date,
whether or not adjusted in accordance with this Section 3.5, shall, in the
aggregate, be in an amount at least sufficient to pay in full principal and
interest payable on the Notes on such Rent Payment Date. Anything herein or in
any other Operative Document to the contrary notwithstanding, Termination Values
(excluding the Equity Portion of Termination Value) payable on any date under
this Facility Lease, whether or not adjusted in accordance with this Section
3.5, shall in the aggregate, together with all other Rent due and owing on such
date, exclusive of any portion thereof that is an Excepted Payment, be in an
amount at least sufficient to pay in full the

                            Conemaugh Facility Lease
                                        7
<PAGE>   12

principal of, premium (other than premium, if any, payable by the Owner Lessor
pursuant to Section 14), if any, and accrued interest on the Notes payable on
such date.

                  (e) Notwithstanding anything herein to the contrary, the
Facility Lessee shall be permitted to defer the Equity Portion of Periodic Lease
Rent and the Equity Portion of Termination Value (or the Equity Portion of a
Qualifying Cash Bid) with respect to the Facility Interest by such amounts and
to such dates as shall be permitted under Section 5.4 of the Tax Indemnity
Agreement; provided, that if Termination Value should become due in connection
with an exercise of remedies following a Lease Event of Default, any such
deferred Rent shall become due and payable.

                  (f) Termination Value shall be adjusted to the extent required
under Section 8 of the Tax Indemnity Agreement.

                  (g) Any adjustment pursuant to this Section 3.5 shall
initially be computed by the Owner Participant or the Equity Investor using the
same method of computation, Tax Assumptions and Pricing Assumptions originally
used (other than those that have changed as the result of the event giving rise
to the adjustment) in the calculation of the Adjustment Items as of the Closing
Date, and shall be subject to the verification procedure described in this
Section 3.5(g) and in compliance with Section 467 of the Code (as in effect at
the date of such adjustment), but only to the extent the original transaction
complied therewith. Once computed, the results of such computation shall
promptly be delivered by the Owner Participant to the Facility Lessee. Within 30
days after the receipt of the results of any such adjustment, the Facility
Lessee may request that a nationally recognized firm of accountants or lease
advisors selected by the Owner Participant and reasonably satisfactory to the
Facility Lessee (the "Verifier") verify, on a confidential basis, after
consultation with the Owner Participant and the Facility Lessee, the accuracy of
such adjustment in accordance with this Section 3.5. The Owner Participant and
the Facility Lessee hereby agree, subject to the execution by the Verifier of an
appropriate confidentiality agreement, to provide the Verifier with all
information and materials (other than the income tax returns or accounting
records of the Equity Investor, the Equity Subsidiary Holding Company, the
Equity Subsidiary or the Owner Participant) as shall be necessary in connection
therewith. Each of the Owner Participant, the Owner Lessor, the Equity Investor
and the Facility Lessee shall have the right to communicate with the Verifier
and submit supporting information and data. If the Verifier confirms that such
adjustment is in accordance with this Section 3.5, it shall so certify to the
Facility Lessee, the Owner Lessor and the Owner Participant and such
certification shall be final, binding and conclusive on the Facility Lessee, the
Owner Participant and the Owner Lessor. If the Verifier concludes that such
adjustment is not in accordance with this Section 3.5, and the adjustments to
the Adjustment Items calculated by the Verifier are different from those
calculated by the Owner Participant, then it shall so certify to the Facility
Lessee, the Owner Lessor and the Owner Participant and the Verifier's
calculation shall be final, binding and conclusive on the Facility Lessee, the
Owner Lessor and the Owner Participant. If the Facility Lessee does not request
verification of any adjustment within the period specified above, the
computation provided by the Owner Participant shall be final, binding and
conclusive on the Facility Lessee, the Owner Lessor and the Owner Participant.
The final determination of any adjustment hereunder shall be set forth in an
amendment to this Facility Lease, executed and delivered by the Owner Lessor and
the Facility Lessee and consented to by the Owner Participant; provided,
however, that any omission to

                            Conemaugh Facility Lease
                                       8
<PAGE>   13

execute and deliver such amendment shall not affect the validity and
effectiveness of any such adjustment. The reasonable fees, costs and expenses of
the Verifier in verifying an adjustment pursuant to this Section 3.5 shall be
paid by the Facility Lessee; provided, however, that, in the event that such
Verifier determines that the present value of Periodic Lease Rent to be made
under this Facility Lease as calculated by the Owner Participant is greater than
the present value of the correct Periodic Lease Rent as certified by the
Verifier, in each case, discounted semi-annually at the Discount Rate, by more
than seven basis points, then such expenses of the Verifier shall be paid by the
Owner Participant. Notwithstanding anything herein to the contrary, the sole
responsibility of the Verifier shall be to verify the calculations hereunder and
matters of interpretation of this Facility Lease or any other Operative Document
shall not be within the scope of the Verifier's responsibilities.

         Section 3.6 Manner of Payments. All Rent (whether Periodic Lease Rent,
Renewal Lease Rent or Supplemental Lease Rent) shall be paid by the Facility
Lessee in Dollars in immediately available funds to the recipient not later than
10:30 a.m. (New York City time) on the date due. All Rent payable to the Owner
Lessor (other than Excepted Payments) shall be paid by the Facility Lessee to
the Owner Lessor at its account at Wilmington Trust Company (ABA #031-100-092
Account No. 52441-0 Attention: Bill Hines), or to such other place as the Owner
Lessor shall notify the Facility Lessee in writing; provided, however, that so
long as the Lien of the Lease Indenture has not been discharged, the Owner
Lessor hereby irrevocably directs (it being agreed and understood that such
direction shall be deemed to have been revoked after the Lien of the Lease
Indenture shall have been fully discharged in accordance with its terms), and
the Facility Lessee agrees, that all payments of Rent (other than Excepted
Payments) payable to the Owner Lessor shall be paid by wire transfer directly to
the Lease Indenture Trustee's Account or to such other place as the Lease
Indenture Trustee shall notify the Facility Lessee in writing pursuant to the
Lease Indenture. Payments constituting Excepted Payments shall be made to the
Person entitled thereto at the address for such Person set forth in the
Participation Agreement, or to such other place as such Person shall notify the
Facility Lessee in writing.

                  (a) Without waiving any claim the Facility Lessee may have
against any manufacturer, vendor or contractor, THE FACILITY LESSEE ACKNOWLEDGES
AND AGREES SOLELY FOR THE BENEFIT OF THE OWNER LESSOR AND THE OWNER PARTICIPANT
THAT (i) THE FACILITY AND EACH COMPONENT THEREOF ARE OF A SIZE, DESIGN, CAPACITY
AND MANUFACTURE ACCEPTABLE TO THE FACILITY LESSEE, (ii) THE FACILITY LESSEE IS
SATISFIED THAT THE FACILITY AND EACH COMPONENT THEREOF ARE SUITABLE FOR THEIR
RESPECTIVE PURPOSES, (iii) NEITHER THE OWNER LESSOR NOR THE OWNER PARTICIPANT IS
A MANUFACTURER OR A DEALER IN PROPERTY OF SUCH KIND, (iv) THE FACILITY INTEREST

INCLUDING (1) ZONING REGULATIONS, (2) ENVIRONMENTAL LAWS OR (3) BUILDING
RESTRICTIONS, AND IN THE STATE AND CONDITION OF EVERY PART THEREOF WHEN THE SAME
FIRST BECAME SUBJECT TO THIS FACILITY LEASE WITHOUT REPRESENTATION OR WARRANTY
OF ANY KIND BY THE OWNER LESSOR OR THE OWNER PARTICIPANT AND (v) THE OWNER
LESSOR LEASES FOR THE BASIC LEASE TERM AND THE RENEWAL LEASE TERMS, IF ANY,
SPECIFIED HEREIN AND THE FACILITY LESSEE TAKES THE FACILITY INTEREST UNDER THIS
FACILITY LEASE "AS-IS", "WHERE-IS" AND "WITH ALL FAULTS", AND THE FACILITY
LESSEE ACKNOWLEDGES THAT NEITHER THE OWNER LESSOR NOR THE OWNER PARTICIPANT
MAKES NOR SHALL BE DEEMED TO HAVE MADE, AND EACH EXPRESSLY DISCLAIMS, ANY AND
ALL RIGHTS, CLAIMS, WARRANTIES OR REPRESENTATIONS, EITHER EXPRESS OR IMPLIED, AS
TO THE VALUE, CONDITION, FITNESS FOR ANY PARTICULAR PURPOSE, DESIGN, OPERATION,
OR MERCHANTABILITY THEREOF OR AS TO THE TITLE OF THE FACILITY, THE QUALITY OF
THE MATERIAL OR WORKMANSHIP THEREOF OR CONFORMITY THEREOF TO SPECIFICATIONS,
FREEDOM FROM PATENT, COPYRIGHT OR TRADEMARK INFRINGEMENT, THE ABSENCE OF ANY
LATENT OR OTHER DEFECT, WHETHER OR NOT DISCOVERABLE, OR AS TO THE ABSENCE OF ANY
OBLIGATIONS BASED ON STRICT LIABILITY IN TORT OR ANY OTHER EXPRESS OR IMPLIED
REPRESENTATION OR WARRANTY WHATSOEVER WITH RESPECT THERETO, except that the
Owner Lessor represents and warrants that on the Closing Date, the Facility
Interest will be free of Owner Lessor's Liens. It is agreed that all such risks,
as between the Owner Lessor and the Owner Participant on the one hand and the
Facility Lessee on the other hand are to be borne by the Facility Lessee with
respect to acts, occurrences or omissions during the Facility Lease Term.
Neither the Owner Lessor nor the Owner Participant shall have any responsibility
or liability to the Facility Lessee or any other Person with respect to any of
the following: (x) any liability, loss or damage caused or alleged to be caused
directly or indirectly by the Facility or any Component or by any inadequacy
thereof or deficiency or defect therein or by any other circumstances in
connection therewith; (y) the use, operation or performance of the Facility or
any Component thereof or any risks relating thereto; or (z) the delivery,
operation, servicing, maintenance, repair, improvement, replacement or
decommissioning of the Facility or any Component thereof. The provisions of this
paragraph (a) of this Section 4.1 have been negotiated, and, except to the
extent otherwise expressly stated, the foregoing provisions are intended to be a
complete exclusion and negation of any representations or warranties of the
Owner Lessor, express or implied, with respect to the Facility or any Components
thereof or the Facility Interest that may arise pursuant to any Applicable Law
now or hereafter in effect, or otherwise.

                  (b) During the Facility Lease Term, so long as no Lease Event
of Default shall have occurred and be continuing, the Owner Lessor hereby
appoints irrevocably and constitutes the Facility Lessee its agent and
attorney-in-fact, coupled with an interest, to assert and enforce, from time to
time, in the name and for the account of the Owner Lessor and the Facility
Lessee, as their interests may appear, but in all cases at the sole cost and
expense of the Facility Lessee, whatever claims and rights the Owner Lessor may
have in respect of the Facility or any Component thereof, or the Facility
Interest against any manufacturer, vendor or contractor, or

under any express or implied warranties relating to the Facility or any
Component thereof, or the Facility Interest.

         Section 4.2 Quiet Enjoyment. So long as no Lease Event of Default has
occurred and is continuing, the Facility Lessee's quiet enjoyment of the
Facility Interest will not be disturbed by the Owner Lessor or any party acting
by, through or under the Owner Lessor. Without limiting any right or remedies
under the Owners Agreement, the right of the Other Facility Owners of the
Facility to quiet enjoyment, if any, will not be disturbed by the Owner Lessor
or any party acting by, through or under the Owner Lessor.

                                    SECTION 5

                           RETURN OF FACILITY INTEREST

         Section 5.1 Return. Upon expiration or termination of this Facility
Lease (other than a termination pursuant to Section 10 or, if the Facility
Interest is being transferred to the Facility Lessee, Sections 13 or 14), the
Facility Lessee, at its own expense, shall return the Facility Interest
(together with an undivided interest equal to the Owner Lessor's Percentage in
all Modifications to the Facility which shall have vested in the Owner Lessor
pursuant to the first sentence of Section 8.3) to the Owner Lessor or any
permitted transferee or assignee of the Owner Lessor by surrendering the
Facility Interest into the possession of the Owner Lessor or such transferee or
assignee at the location of the Facility on the Facility Site. In connection
with such return, the Facility Lessee shall (a) assign, to the extent permitted
by Applicable Law and not already assigned to the Owner Lessor, a corresponding
undivided interest equal to the Owner Lessor's Percentage in, and shall
cooperate with all reasonable requests of the Owner Participant, the Owner
Lessor or a permitted transferee or assignee of either of such parties for
purposes of obtaining, or enabling the Owner Participant, the Owner Lessor or
such transferees or assignees to obtain, any and all material Governmental
Approvals and licenses, permits, approvals and consents of any Governmental
Entities or other Persons that are or will be required to be obtained by the
Owner Participant, the Owner Lessor or such transferee or assignee in connection
with the use, operation or maintenance of the Facility Interest on or after such
return in compliance with the Owners Agreement, agreements and contracts
permitted by Section 5.21 of the Participation Agreement and Applicable Law
including, without limitation, any fuel supply, interconnection, power purchase
or other agreements with respect to the Facility Interest; and (b) provide the
Owner Lessor or a permitted transferee or assignee of the Owner Lessor copies of
all documents, instruments, plans, maps, specifications, manuals, drawings and
other documentary materials relating to the installation, maintenance,
operation, construction, design, modification and repair of the Facility, as
shall be in the Facility Lessee's possession and shall be reasonably appropriate
or necessary for the continued operation of the Facility. Upon such return, the
right to use the Facility Interest granted hereunder for the benefit of the
Facility Lessee shall cease and terminate.

         Section 5.2 Condition Upon Return. At the time of a return of the
Facility Interest by the Facility Lessee pursuant to Section 5.1 (other than a
return pursuant to Section 13 or 14), the following conditions shall be complied
with, all at the Facility Lessee's sole cost and expense:

                            Conemaugh Facility Lease
                                       11
<PAGE>   16

                  (a) the Facility will be in at least as good condition as if
it had been maintained, repaired and operated during the Facility Lease Term in
compliance with the provisions of this Facility Lease (including, without
limitation, the provisions of Section 7), ordinary wear and tear excepted, and
there shall be no deferred maintenance in respect of the Facility;

                  (b) the Facility Interest shall be free and clear of all Liens
other than Permitted Liens set forth in clauses (ii), (iii), (iv), (vi), (viii)
and (ix) of the definition thereof; provided, however, that nothing in this
Section 5.2(b) shall limit the obligations of the Facility Lessee under Section
10.1 of the Participation Agreement;

                  (c) the Facility shall have at least the capability and
functional ability, as certified by an independent professional engineer
selected pursuant to the Independent Engineer Selection Procedure, to generate
electricity, on a continuous basis in normal commercial operating conditions,
substantially at the ratings for which it was designed after taking into account
all Modifications to the Facility made in accordance with this Facility Lease
(ordinary wear and tear excepted);

                  (d) the Facility shall be in material compliance with all
requirements of manufacturers required for the maintenance in full force and
effect of any material warranty then in effect with respect to the Facility;

                  (e) no Component of the Facility shall be a temporary
Component and any replacement Component of the Facility shall satisfy the
standards of Section 7.2; and

                  (f) the Facility Lessee, at the request of the Owner Lessor,
shall sell pursuant to Section 8.3 (subject to all existing encumbrances) to the
Owner Lessor (or its designee or transferee) all Optional Modifications which
are Severable Modifications or an undivided interest in such Optional
Modifications which are Severable Modifications made to the Facility which are
owned by the Facility Lessee (other than Severable Modifications referred to in
the first sentence of Section 8.3).

                  In addition to the foregoing conditions, the Facility Lessee,
or an Affiliate thereof, shall enter into an agreement or other arrangements
reasonably acceptable to the Owner Lessor, which arrangements, however, shall
not be a condition precedent to the return of the Facility Interest (the
"Support Arrangements") to provide the Owner Lessor with the Support Services;
provided, that the Facility Lessee shall be bound to provide Support Services
only to the extent the Facility Lessee or any domestic, unregulated Affiliate
thereof is capable of providing such services and is either in the business of
providing such Support Services to others or performing such Support Services on
its own behalf, and only to the extent that such services cannot reasonably and
timely be obtained by the Owner Lessor or its Affiliates from third parties.
Support Arrangements shall provide for the provision of Support Services during
and after the expiration of this Facility Lease, and will provide for fair
market value compensation from time to time to be paid to the Facility Lessee,
or an Affiliate thereof, for the performance of such Support Services,
periodically in advance on no less than on an annual basis, for such rights and
the performance of other services and all such arrangements shall terminate upon
expiration or early termination of the Site Lease Term or at the Owner Lessor's
option. Within 180 days after

                            Conemaugh Facility Lease
                                       12
<PAGE>   17

the expiration or termination of this Facility Lease, the Owner Lessor shall
notify the Facility Lessee of the material elements of the Support Services that
the Owner Lessor desires the Facility Lessee, or its Affiliate, to continue to
perform. Following such notice, the Facility Lessee and the Owner Lessor shall
negotiate in good faith the terms of the fair market value, performance
standards, compensation and other terms of such specified Support Services,
including the circumstances under which the Facility Lessee and its Affiliates
shall be released of any further obligation to provide such Support Services,
and enter into contracts for the performance of the Support Services upon any
such negotiated terms. Other than the Support Services covered by such
contracts, the Facility Lessee will have no further obligation to provide
Support Services.

         Section 5.3 Environmental Reports. In connection with the return of the
Facility Interest pursuant to Section 5.2, the Facility Lessee shall, at its own
expense, provide the Owner Lessor and the Owner Participant and, so long as the
Lien of the Lease Indenture shall not have been terminated or discharged, the
Lease Indenture Trustee (a) not later than 180 days prior to the later of the
Expiration Date or the last day of the last Renewal Lease Term elected by the
Facility Lessee, or (b) in connection with any return pursuant to Section 17, as
promptly as possible after a request therefor by the Owner Lessor, the Owner
Participant or, so long as the Lien of the Lease Indenture shall not have been
terminated or discharged, the Lease Indenture Trustee, a phase I environmental
survey, which shall be expanded to a phase II environmental survey if, as a
result of the phase I survey, facts are revealed that would reasonably
necessitate a phase II survey, prepared by a reputable environmental consulting
firm (selected by the Facility Lessee and reasonably acceptable to the Owner
Participant) as to the environmental condition of the Facility and the Facility
Site and the compliance or non-compliance with applicable Environmental Laws and
the presence or absence of Environmental Conditions, in form and scope
reasonably satisfactory to the Owner Participant. The provisions of such surveys
shall not relieve the Facility Lessee of liability with respect to Environmental
Conditions, known or unknown, in respect of the Facility Interest or the
Facility Site and the Facility Lessee will take any and all actions necessary to
ensure that the Facility Interest and the Facility Site comply with all such
Environmental Laws. If such survey shall indicate that the Facility Interest or
the Facility Site is not then in compliance with then applicable Environmental
Laws, the Facility Lessee shall, within 90 days of the Owner Lessor having
received such survey, provide the Owner Participant and, so long as the Lien of
the Lease Indenture shall not have been terminated or discharged, the Lease
Indenture Trustee, with a remediation or compliance plan designed to ensure that
the Facility Interest and the Facility Site will be brought into compliance with
applicable Environmental Laws and all material Environmental Conditions
recommended for correction in such survey will be corrected as promptly as is
reasonably practical and without materially adversely affecting the continued
operation of such Facility. The Facility Lessee shall at its expense perform
such cleanup or remediation and achieve compliance as soon as reasonably
practicable. The obligations of the Facility Lessee set forth in this Section
5.3 shall survive the termination of this Facility Lease and the expiration of
the Facility Lease Term.

                                      LIENS

         The Facility Lessee covenants that it will not directly or indirectly
create, incur, assume or suffer to exist any Lien on or with respect to the
Facility Interest, the Facility Site or any Component, or any interest therein
or in, to or on its interest in this Facility Lease or its interest in any other
Operative Document, except Permitted Liens, and the Facility Lessee shall
promptly notify the Owner Lessor of the imposition of any such Lien of which the
Facility Lessee is aware and shall promptly, at its own expense, take such
action as may be necessary to fully discharge or release any Lien. The Facility
Lessee shall defend the Owner Lessor from and against all claims to the Owner
Lessor's title to the Facility Interest or any portion thereof (except for Owner
Lessor's Liens, Owner Participant's Liens and Permitted Encumbrances).

                                    SECTION 7

                     MAINTENANCE; REPLACEMENTS OF COMPONENTS

         Section 7.1 Maintenance. The Facility Lessee, at its own cost and
expense, will exercise all rights, powers, elections and options available to it
or any of its Affiliates under the Owners Agreement to (a) cause the Facility to
be maintained in good condition, repair and working order, ordinary wear and
tear excepted, and in any event, in all material respects (i) in accordance with
Prudent Industry Practice, (ii) in compliance with all Applicable Law, including
without limitation all Environmental Laws and safety laws, unless such
noncompliance could not reasonably be expected to result in a Material Adverse
Effect or involve any (1) danger of foreclosure, sale, forfeiture or loss of, or
imposition of a lien on, the Facility, the Facility Interest or the Facility
Site or the impairment of the use, operation or maintenance of the Facility or
the Facility Site in any material respect, or (2) risk of criminal liability
being incurred by the Equity Investor, the Equity Subsidiary Holding Company,
the Equity Subsidiary, the Owner Participant, the Owner Lessor, the Lessor
Manager, the Lease Indenture Trustee or the Pass Through Trustee or any of their
Affiliates or (3) material risk of the occurrence of any material adverse effect
being incurred by the Equity Investor, the Equity Subsidiary Holding Company,
the Equity Subsidiary, the Owner Participant, the Owner Lessor, the Lessor
Manager, the Lease Indenture Trustee or the Pass Through Trustee, and (iii) in
accordance with the terms of all insurance policies required to be maintained
pursuant to Section 11, and (b) cause to be made all necessary repairs,
renewals, replacements, betterments and improvements thereof, all as in the
reasonable judgment of the Facility Lessee may be necessary so that the Facility
Interest may be operated in accordance with the Operative Documents, provided,
however, that such obligation hereunder shall be limited to the exercise of all
rights, powers, elections and options available to the Facility Lessee or any of
its Affiliates under the Owners Agreement.

         Section 7.2 Replacement of Components. In the ordinary course of
maintenance, service, repair or testing of the Facility or any Component, the
Facility Lessee or the Operator, at its own cost and expense, may remove or
cause or permit to be removed from the Facility any Component; provided,
however, that the Facility Lessee shall exercise all rights, powers, elections
and options available to it or any of its Affiliates under the Owners Agreement
to (a) cause such Component to be replaced by a replacement Component which
shall be free and

                            Conemaugh Facility Lease
                                       14
<PAGE>   19

clear of all Liens (except Permitted Liens) and in as good operating condition
as the Component replaced, assuming that the Component replaced was maintained
in accordance with this Facility Lease, and assuming the Facility shall then be
in the condition required to have been maintained by the terms of this Facility
Lease (each such replacement Component being herein referred to as a
"Replacement Component") and (b) cause such replacement to be performed in a
manner which does not diminish the current or residual value, remaining useful
life or utility of the Facility by more than a de minimis amount below the then
current or residual value, the remaining useful life or the utility thereof
immediately prior to such replacement or cause the Facility to become
"limited-use" property within the meaning of Rev. Proc. 75-28, 1975-1 C.B. 752
or Rev. Proc. 76-30, 1976-2 C.B. 647; provided, further, that the Facility
Lessee's obligations hereunder shall be limited to its exercise of all rights,
powers, elections and options available to it or any of its Affiliates under the
Owners Agreement. An undivided interest equal to the Owner Lessor's Percentage
in each Component of the Facility which is subject to this Facility Lease, at
any time removed from the Facility, shall remain subject to this Facility Lease,
wherever located, until such time as such Component shall be replaced by a
Replacement Component which has been incorporated in the Facility and which
meets the requirements for Replacement Components specified above. Immediately
upon any Replacement Component becoming incorporated in the Facility, without
further act (and at no cost to the Owner Lessor and with no adjustment to the
Purchase Price or Periodic Lease Rent or Allocated Rent), (i) the replaced
Component shall no longer be subject to this Facility Lease, (ii) title to the
Owner Lessor's undivided interest equal to the Owner Lessor's Percentage in the
removed Component (to the extent part of the Facility Interest) shall thereupon
vest in the Facility Lessee or such other Person as shall be designated by the
Facility Lessee, free and clear of all rights of the Owner Lessor and the Lease
Indenture Trustee, and (iii) title to an undivided interest equal to the Owner
Lessor's Percentage in the Replacement Component shall thereupon vest with the
Owner Lessor and such undivided interest shall (x) become subject to this
Facility Lease and, so long as the Lien of the Lease Indenture shall not have
been terminated or discharged, the Lien of the Lease Indenture, and (y) be
deemed a part of the Facility and the Facility Interest for all purposes of this
Facility Lease. Notwithstanding anything in this Section 7.2 or elsewhere in
this Facility Lease to the contrary, but subject to the Owners Agreement, if the
Facility Lessee has determined that a Component is surplus or obsolete, it shall
have the right to remove such Component without replacing it; provided, that no
such Component may be so removed without being replaced if such removal would
diminish the current or residual value, remaining useful life or utility of the
Facility or the Facility Interest by more than a de minimis amount below the
current or residual value, the remaining useful life or the utility thereof
immediately prior to such removal, assuming the Facility Interest shall then be
in the condition required to have been maintained by the terms of this Facility
Lease or cause the Facility to become "limited use" property within the meaning
of Rev. Proc. 75-28, 1975-1 C.B. 752 or Rev. Proc. 76-30, 1976-2 C.B. 647.

         Section 7.3 Environmental Matters. The Facility Lessee will, at its own
expense, exercise all rights, powers, elections and options available to it or
any of its Affiliates under the Owners Agreement to:

                  (a) comply with all Environmental Laws applicable to the
Facility or the Facility Site, except for those the failure to comply with could
not reasonably be expected to have a Material Adverse Effect or involve any (1)
danger of foreclosure, sale, forfeiture or loss

Facility Site or the impairment of the use, operation or maintenance of the

liability being incurred by the Equity Investor, the Equity Subsidiary Holding
Company, the Equity Subsidiary, the Owner Participant, the Owner Lessor, the
Lessor Manager, the Lease Indenture Trustee or the Pass Through Trustee or any
of their Affiliates or (3) material risk of the occurrence of any material
adverse effect being incurred by the Equity Investor, the Equity Subsidiary
Holding Company, the Equity Subsidiary, the Owner Participant, the Owner Lessor,
the Lessor Manager, the Lease Indenture Trustee or the Pass Through Trustee, and
as between the Owner Lessor and the Facility Lessee, the Facility Lessee shall
have the sole responsibility for any and all costs and expenses associated with
such compliance;

                  (b) obtain, comply and maintain all necessary Governmental
Approvals required under any applicable Environmental Law, in connection with
the use, operation and maintenance of the Facility and the Facility Site except
for those the failure to comply with could not reasonably be expected to have a
Material Adverse Effect or involve any (1) danger of foreclosure, sale,
forfeiture or loss of, or imposition of a lien on, the Facility, the Facility
Interest or the Facility Site or the impairment of the use, operation or
maintenance of the Facility or the Facility Site in any material respect, or (2)
risk of criminal liability being incurred by the Equity Investor, the Equity
Subsidiary Holding Company, the Equity Subsidiary, the Owner Participant, the
Owner Lessor, the Lessor Manager, the Lease Indenture Trustee or the Pass
Through Trustee or any of their Affiliates or (3) material risk of the
occurrence of any material adverse effect being incurred by the Equity Investor,
the Equity Subsidiary Holding Company, the Equity Subsidiary, the Owner
Participant, the Owner Lessor, the Lessor Manager, the Lease Indenture Trustee
or the Pass Through Trustee;

                  (c) conduct and complete, at no cost and expense to the Owner
Participant or the Owner Lessor, any investigation, study, sampling, monitoring
and testing and undertake any cleanup, removal, remedial, corrective,
mitigation, response or other action necessary or advisable to abate, correct,
remove and clean up the Facility or the Facility Site, to the extent required by
and in compliance with applicable Environmental Laws, except for those the
failure to comply with could not reasonably be expected to have a Material
Adverse Effect or involve any (1) danger of foreclosure, sale, forfeiture or
loss of, or imposition of a lien on, the Facility, the Facility Interest or the
Facility Site or the impairment of the use, operation or maintenance of the
Facility or the Facility Site in any material respect, or (2) risk of criminal
liability being incurred by the Equity Investor, the Equity Subsidiary Holding
Company, the Equity Subsidiary, the Owner Participant, the Owner Lessor, the
Lessor Manager, the Lease Indenture Trustee or the Pass Through Trustee or any
of their Affiliates or (3) material risk of the occurrence of any material
adverse effect being incurred by the Equity Investor, the Equity Subsidiary
Holding Company, the Equity Subsidiary, the Owner Participant, the Owner Lessor,
the Lessor Manager, the Lease Indenture Trustee or the Pass Through Trustee; and

                  (d) as soon as possible and in any event within fifteen
Business Days of the Facility Lessee obtaining Actual Knowledge thereof, provide
the Owner Lessor with written notice of, and copies of all written
communications relating to, any pending or threatened material claim arising
from a violation of or liability under any Environmental Law involving the
Facility or the Facility Site that could be expected to have a Material Adverse
Effect or involve

Subsidiary, the Owner Participant, the Owner Lessor, the Lessor Manager, the
Lease Indenture Trustee or the Pass Through Trustee or any of their Affiliates
or (3) material risk of the occurrence of any material adverse effect being
incurred by the Equity Investor, the Equity Subsidiary Holding Company, the
Equity Subsidiary, the Owner Participant, the Owner Lessor, the Lessor Manager,
the Lease Indenture Trustee or the Pass Through Trustee. To the extent possible,
all such notices shall describe in reasonable detail the nature of the claim,
and the Facility Lessee's plans for responding to such claim.

                                    SECTION 8

                                  MODIFICATIONS

         Section 8.1 Required Modifications. The Facility Lessee, at its own
cost and expense, shall exercise all rights, powers, elections and options
available to it or any of its Affiliates under the Owners Agreement to make or
cause or permit to be made all Modifications to the Facility as they relate to
the Facility Interest as are required by Applicable Law (each, a "Required
Modification"); provided, however, that the Facility Lessee may, in good faith
and by appropriate proceedings, diligently contest the validity or application
of any Applicable Laws in any reasonable manner which does not involve any (i)
danger of foreclosure, sale, forfeiture or loss of any part of the Facility
Interest or the impairment of the use, operation or maintenance of the Facility
in any material respect, (ii) any risk of criminal liability asserted against
the Owner Lessor, the Owner Participant, the Equity Subsidiary Holding Company,
the Equity Subsidiary, the Equity Investor or any of their respective
Affiliates, or (iii) material risk of the occurrence of any material adverse
effect being incurred by the Owner Participant, the Owner Lessor, the Equity
Subsidiary, the Equity Subsidiary Holding Company, the Equity Investor, the
Lease Indenture Trustee or the Pass Through Trustee including, without
limitation, subjecting any such Person to regulation as a public utility under
Applicable Law; provided further, that no such contest may extend beyond the
expiration or earlier termination of this Facility Lease.

         Section 8.2 Optional Modifications. The Facility Lessee at any time
may, at its own cost and expense, subject to the Owners Agreement, make or cause
or permit to be made any Modification to the Facility as the Facility Lessee
considers desirable in the proper conduct of its business (any such non-Required
Modification being referred to as an "Optional Modification"); provided that the
Facility Lessee shall exercise all rights, powers, elections and options
available to it or any of its Affiliates under the Owners Agreement to prevent
any Optional Modification from being made to the Facility that would diminish by
more than a de minimis amount the current or residual value, remaining useful
life or utility of the Facility below the current or residual value, remaining
useful life or utility of the Facility immediately prior to such Optional
Modification assuming the Facility was then in the condition required to be
maintained by the terms of this Facility Lease, or cause the Facility to become
"limited use" property, within the meaning of Rev. Proc. 75-28, 1975-1 C.B. 752
or Rev. Proc. 76-30, 1976-2 C.B. 647.

         Section 8.3 Title to Modifications. Title to an undivided interest
equal to the Owner Lessor's Percentage in (a) all Required Modifications, (b)
all Nonseverable Modifications and (c) all Modifications financed by the Owner
Lessor by an Additional Equity Investment or a Supplemental Financing pursuant
to Section 12.1 of the Participation Agreement shall (at no cost to the Owner
Lessor and with no adjustment to the Purchase Price or, except as provided
herein, Periodic Lease Rent, Renewal Lease Rent or Allocated Rent) immediately
vest in the Owner Lessor, and such undivided interest shall immediately (i)
become subject to this Facility Lease and, so long as the Lien of the Lease
Indenture shall not have been terminated or discharged, the Lien of the Lease
Indenture, and (ii) be deemed part of the Facility Interest for all purposes of
this Facility Lease. The Facility Lessee, at its own cost and expense, shall
take such steps as the Owner Lessor and, so long as the Lien of the Lease
Indenture shall not have been terminated or discharged, the Lease Indenture
Trustee may reasonably require from time to time to confirm that title in such
undivided interest has vested in the Owner Lessor and that such undivided
interest is subject to this Facility Lease and, so long as the Lien of the Lease
Indenture shall not have been terminated or discharged, the Lien of the Lease
Indenture. No interest in any Optional Modification which is a Severable
Modification (other than Severable Modifications which are financed by the Owner
Lessor by an Additional Equity Investment or a Supplemental Financing pursuant
to Section 12.1 of the Participation Agreement) shall vest in the Owner Lessor
or become subject to this Facility Lease or the Lien of the Lease Indenture;
provided, however, that if the Facility Lessee shall, at its cost and expense,
cause such Optional Modifications which are Severable Modifications to be made
to the Facility, the Owner Lessor shall have the right, immediately prior to the
return of the Facility Interest to the Owner Lessor hereunder, to purchase an
undivided interest equal to the Owner Lessor's Percentage in any such Optional
Modifications which are Severable Modifications. The purchase price for such
undivided interest shall be the then Fair Market Sales Value of such undivided
interest. If the Owner Lessor does not elect to purchase such Optional
Modifications which are Severable Modifications, the Facility Lessee may, to the
extent permitted by the Owners Agreement, remove such Modifications at the end
of the Facility Lease Term and the Facility Lessee shall repair any damage to
the Facility and the Facility Site caused by such removal, all at the Facility
Lessee's cost and expense; provided, however, that such removal shall not (i)
diminish the value, remaining useful life or utility of the Facility by more
than a de minimis amount assuming the Facility would have been at the time of
removal in the condition required to be maintained by the terms of this Facility
Lease, or (ii) cause the Facility to become "limited use" property, within the
meaning of Rev. Proc. 75-28, 1975-1 C.B. 752 or Rev. Proc. 76-30, 1976-2 C.B.
647. If the Facility Lessee shall have failed to remove any Optional
Modifications which are Severable Modifications as above provided prior to the
return of the Facility Interest to the Owner Lessor hereunder, title to an
undivided interest equal to the Owner Lessor's Percentage in such Modifications
shall (at no cost to the Owner Lessor) vest in the Owner Lessor.

                                    SECTION 9

                                    NET LEASE

         This Facility Lease is a "net lease" and the Facility Lessee's
obligation to make all Rent payments payable hereunder or other payments under
the Operative Documents (and all amounts, including Termination Value, following
termination of this Facility Lease) shall be absolute and unconditional under
any and all circumstances, and shall not be terminated,

extinguished, diminished, lost or otherwise impaired by any circumstance of any
character, including by (i) any setoff, counterclaim, recoupment, defense or
other right which the Facility Lessee may have against the Owner Lessor, the
Owner Participant, the Equity Subsidiary, the Equity Investor, the Pass Through
Trustee, the Lease Indenture Trustee or any other Person, including any claim as
a result of any breach by any of said parties of any covenant or provision in
this Facility Lease or any other Operative Document, (ii) any lack or invalidity
of title or any defect in the title, condition, design, operation,
merchantability or fitness for use of the Facility or any Component thereof, or
any eviction by paramount title or otherwise, or any unavailability of the
Facility, the Facility Site, any Component thereof, any other portion of the
Facility Interest, or any part thereof, (iii) any loss or destruction of, or
damage to, the Facility or any Component thereof or interruption or cessation in
the use or possession thereof or any part thereof by the Facility Lessee for any
reason whatsoever and of whatever duration, (iv) the condemnation,
requisitioning, expropriation, seizure or other taking of title to or use of the
Facility Site, the Facility, any Component thereof, or any other portion of the
Facility Interest by any Governmental Entity or otherwise, (v) the invalidity or
unenforceability or lack of due authorization or other infirmity of this
Facility Lease or any other Operative Document, (vi) the lack of right, power or
authority of the Owner Lessor to enter into this Facility Lease or any other
Operative Document, (vii) any ineligibility of the Facility or any Component
thereof for any particular use, whether or not due to any failure of the
Facility Lessee to comply with any Applicable Law, (viii) any event of "force
majeure" or any frustration, (ix) any legal requirement similar or dissimilar to
the foregoing, any present or future law to the contrary notwithstanding, (x)
any insolvency, bankruptcy, reorganization or similar proceeding by or against
the Facility Lessee or any other Person, (xi) any Lien of any Person with
respect to the Facility Site, the Facility, any Component thereof, any other
portion of the Facility Interest or any part thereof, or (xii) any other cause,
whether similar or dissimilar to the foregoing, any present or future law
notwithstanding, except as expressly set forth herein or in any other Operative
Document, it being the intention of the parties hereto that all Rent (and all
amounts, including Termination Value, following termination of this Facility
Lease) payable by the Facility Lessee hereunder shall continue to be payable in
all events in the manner and at times provided for herein. Such Rent (and all
amounts, including Termination Value, following termination of this Facility
Lease) shall not be subject to any abatement and the payments thereof shall not
be subject to any setoff or reduction for any reason whatsoever, including any
present or future claims of the Facility Lessee or any other Person against the
Owner Lessor or any other Person under this Facility Lease or otherwise. To the
extent permitted by Applicable Law, the Facility Lessee hereby waives any and
all rights which it may now have or which at any time hereafter may be conferred
upon it, by statute or otherwise, to terminate, cancel, quit or surrender this
Facility Lease with respect to the Facility Interest except in accordance with
Sections 10, 13, 14 or 15. If for any reason whatsoever this Facility Lease
shall be terminated in whole or in part by operation of law or otherwise, except
as specifically provided herein, the Facility Lessee nonetheless agrees, to the
extent permitted by Applicable Law, to pay to the Owner Lessor an amount equal
to each installment of Periodic Lease Rent, Renewal Lease Rent and all
Supplemental Lease Rent due and owing, at the time such payment would have
become due and payable in accordance with the terms hereof had this Facility
Lease not been so terminated. Nothing contained herein shall be construed to
waive any claim which the Facility Lessee might have under any of the Operative
Documents or otherwise or to limit the right of the Facility Lessee to

make any claim it might have against the Owner Lessor or any other Person or to
pursue such claim in such manner as the Facility Lessee shall deem appropriate.

                                   SECTION 10

                                 EVENTS OF LOSS

         Section 10.1 Occurrence of Events of Loss. The Owner Participant or the
Owner Lessor will promptly notify the Facility Lessee of any event of which it
is aware that, upon election of the Owner Participant, would result in a
Regulatory Event of Loss; provided, however, that the failure to provide such
notice shall not result in any liability with respect to the Owner Participant
or the Owner Lessor and shall not in any way relieve the Facility Lessee of any
of its obligations under this Facility Lease, including the obligations under
this Section 10. If an Event of Loss described in clauses (a) or (b) of the
definition of Event of Loss shall occur, then no later than nine months
following such occurrence the Facility Lessee shall notify the Owner Lessor, the
Owner Participant 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
Trustee in writing of its election to either (a) rebuild or replace the Facility
in accordance with the Operative Documents and the Owners Agreement so that the
Facility shall have a current and residual value, remaining useful life and
utility at least equal to that of the Facility prior to such Event of Loss,
assuming the Facility was in the condition and repair required to be maintained
by this Facility Lease or (b) terminate this Facility Lease with respect to the
Facility Interest and purchase the Facility Interest from the Owner Lessor by
paying to the Owner Lessor an amount equal to the applicable Termination Value
and paying to the parties entitled thereto all other amounts payable pursuant to
Section 10.2. The Facility Lessee may elect the option provided in clause (b) of
the preceding sentence regardless of whether the Facility is to be rebuilt or
replaced. If the Facility Lessee fails to make an election as provided above, an
Event of Loss shall be deemed to occur as of the end of the nine month period
referred to in the second sentence of this Section 10.1 and the Facility Lessee
will be deemed to have made the election to terminate this Facility Lease with
respect to the Facility Interest and purchase the Facility Interest from the
Owner Lessor by paying to the Owner Lessor an amount equal to the applicable
Termination Value and paying to the parties entitled thereto all other amounts
payable pursuant to Section 10.2.

         Section 10.2 Payment of Termination Value; Termination of Periodic
Lease Rent.

                  (a) If any of (x) an Event of Loss described in clause (a) or
(b) of the definition of Event of Loss shall have occurred and the Facility
Lessee shall elect not to rebuild or replace the Facility pursuant to Section
10.1(a), (y) an Event of Loss shall be deemed to occur pursuant to the last
sentence of Section 10.1, or (z) an Event of Loss described in clause (c) or (d)
of the definition of Event of Loss shall occur, then, in the case of clause (x),
on the next Termination Date after the Facility Lessee's notice of its election
referred to in the second sentence of Section 10.1, in the case of clause (y),
on the next Termination Date, after the occurrence of a deemed Event of Loss
pursuant to the last sentence of Section 10.1 or, in the case of clause (z), on
the next Termination Date occurring at least three months after the occurrence
of such Event of Loss or, if earlier, at least one month after receipt of
insurance proceeds in respect of such Event of Loss the Facility Lessee shall
pay to the Owner Lessor (A) the

                            Conemaugh Facility Lease
                                       20
<PAGE>   25

Termination Value determined as of the relevant Termination Date, plus (B) all
amounts of Supplemental Lease Rent (including all documented out-of-pocket costs
and expenses of the Owner Lessor, the Owner Participant, the Lease Indenture
Trustee, the Equity Investor, the Equity Subsidiary Holding Company, the Equity
Subsidiary and the Pass Through Trustee, and all sales, use, value added and
other Taxes required to be indemnified by the Facility Lessee pursuant to
Section 10.2 of the Participation Agreement associated with the exercise of the
termination option pursuant to this Section 10.2) due and payable or unpaid or
accrued on or prior to such Termination Date, plus (C) any unpaid Periodic Lease
Rent due before (but not on) such Termination Date. On the date the Facility
Lessee is required to pay Termination Value pursuant to this Section 10.2, the
balance of the Lessor Section 467 Loan Balance or the Lessee Section 467 Loan
Balance (as the case may be) shall be reduced to zero and shall be fully
discharged for all purposes.

                  (b) Concurrently with the payment of all sums required to be
paid pursuant to this Section 10.2, (i) Periodic Lease Rent or Renewal Lease
Rent, as applicable, shall cease to accrue, (ii) the Facility Lessee's
obligations under Sections 6, 7, 8, 11 and 12 shall terminate, (iii) the
Facility Lessee shall cease to have any other liability to the Owner Lessor, the
Owner Participant and its Affiliates with respect to the Facility Interest
except for Supplemental Lease Rent and other obligations (including those under
Sections 10.1 and 10.2 of the Participation Agreement and under the Tax
Indemnity Agreement) surviving pursuant to the express provisions of any
Operative Document, (iv) the Owner Lessor shall pay the outstanding principal
and accrued interest on the Notes (excluding any Make Whole Premium, if any, due
and payable) pursuant to Section 2.10(a) of the Lease Indenture, (v) this
Facility Lease shall terminate, (vi) the Owner Lessor shall transfer (by an
appropriate instrument of transfer in form and substance reasonably satisfactory
to the Owner Lessor and prepared and recorded by and at the expense of the
Facility Lessee) all of its right, title and interest in and to the Owner
Lessor's Interest to the Facility Lessee, on an "as is", "where is" and "with
all faults" basis, without representations or warranties other than a warranty
as to the absence of Owner Lessor's Liens and a warranty of the Owner
Participant as to the absence of Owner Participant's Liens; and (vii) the Owner
Lessor shall execute and deliver appropriate releases and other documents or
instruments necessary or desirable to effect the foregoing, all to be prepared,
filed and recorded (as appropriate) at the cost and expense of the Facility
Lessee.

                  (c) Notwithstanding the foregoing provisions of paragraphs (a)
and (b) of this Section 10.2, in the case of a Regulatory Event of Loss, if (i)
the Facility Lessee shall have executed and delivered an assumption agreement to
assume the Notes as permitted by and in accordance with Section 2.10(b) of the
Lease Indenture, (ii) all other conditions contained in Section 2.10(b) of the
Lease Indenture shall have been satisfied, and (iii) no Significant Lease
Default or Lease Event of Default shall have occurred and be continuing after
giving effect to such assumption, then, the obligation of the Facility Lessee to
pay Termination Value with respect to the Facility Interest shall be reduced by
the outstanding principal amount and accrued interest of the Notes so assumed by
the Facility Lessee, and the Owner Lessor shall have no obligation to prepay the
outstanding principal and accrued interest on the Notes. On the date the
Facility Lessee is required to pay such amount pursuant to this Section 10.2(c),
the balance of the Lessor Section 467 Loan Balance or the Lessee Section 467
Loan Balance (as the case may be) shall be reduced to zero and shall be fully
discharged for all purposes.

                  (d) Any payments received at any time by the Owner Lessor, the
Lease Indenture Trustee or the Facility Lessee from any Governmental Entity as a
result of the occurrence of an Event of Loss described in clause (c) of the
definition of Event of Loss or from insurance proceeds as a result of the
occurrence of an Event of Loss described in clause (a) or (b) of the definition
of Event of Loss shall be applied as follows:

                  (i) all such payments received at any time by the Facility
         Lessee shall be promptly paid to the Owner Lessor or if the Lien of the
         Lease Indenture shall not have been terminated or discharged, to the
         Lease Indenture Trustee, for application pursuant to the following
         provisions of this Section 10.2, except that so long as no Significant
         Lease Default or Lease Event of Default shall have occurred and be
         continuing (other than Lease Events of Default arising as a result of
         such Event of Loss), the Facility Lessee may retain any amounts that
         the Owner Lessor would at the time be obligated to pay to the Facility
         Lessee as reimbursement under the provisions of paragraph (ii) below;

                  (ii) so much of such payments as shall not exceed the amount
         required to be paid by the Facility Lessee pursuant to paragraph (a) of
         this Section 10.2 shall be applied in reduction of the Facility
         Lessee's obligation to pay such amount if not already paid by the
         Facility Lessee or, if already paid by the Facility Lessee, shall, so
         long as no Significant Lease Default or Lease Event of Default (other
         than Lease Events of Default arising as a result of such Event of Loss)
         shall have occurred and be continuing, be applied to reimburse the
         Facility Lessee for its payment of such amount; and

                  (iii) the balance, if any, of such payments remaining
         thereafter shall be apportioned between the Owner Lessor and the
         Facility Lessee as their respective interests may appear.

         Notwithstanding the foregoing, if the Facility Lessee shall have
elected to rebuild or replace the Facility pursuant to Section 10.1(a), any
insurance proceeds received by the Owner Lessor, the Lease Indenture Trustee or
the Facility Lessee as a result of the occurrence of an Event of Loss described
in clause (a) or (b) of the definition of Event of Loss shall be applied as
provided in Section 11.7.

         Section 10.3 Rebuild or Replace. The Facility Lessee's right to rebuild
or replace any Facility pursuant to clause (a) of Section 10.1 shall be subject
to the fulfillment, at the Facility Lessee's sole cost and expense, in addition
to the conditions contained in said clause (a), of the following conditions:

                  (a) no Lease Event of Default shall have occurred and be
continuing;

                  (b) on the date the Facility Lessee shall give notice pursuant
to Section 10.1(a) of its election to rebuild or replace the Facility in
accordance with this Section 10.3, either (i) the Owner Participant shall have
received an opinion reasonably satisfactory to it from Skadden, Arps, Slate,
Meagher & Flom (Illinois) or its affiliates, or from a nationally recognized tax
counsel selected by the Owner Participant and reasonably acceptable to the
Facility Lessee, to the effect that such rebuilding would not result in any
unindemnified tax consequences (determined based on the indemnification
provisions contained in the Operative

Documents) to the Owner Participant, (ii) an indemnity against such risk in form
and substance reasonably satisfactory to the Owner Participant from or
guaranteed by an entity that meets the Minimum Credit Rating, or (iii) any other
indemnity arrangements against such risk satisfactory to the Owner Participant;

                  (c) on the date the Facility Lessee shall give notice pursuant
to Section 10.1(a) of its election to rebuild or replace the Facility in
accordance with this Section 10.3, the Facility Lessee shall deliver to the
Owner Participant and, so long as the Lien of the Lease Indenture shall not have
been terminated or discharged, the Lease Indenture Trustee (i) a report of the
Engineering Consultant, or such other independent engineer reasonably
satisfactory to the Owner Participant and, so long as the Lien of the Lease
Indenture shall not have been terminated or discharged, the Lease Indenture
Trustee, to the effect that the rebuilding or replacement of the Facility is
technologically feasible and economically viable and that such rebuilding or
replacement can be completed by a date that is 36 months prior to the end of the
Basic Lease Term or 12 months prior to the expiration of any Renewal Lease Term
then in effect or which has been elected by the Facility Lessee, and (ii) an
appraisal of an Independent Appraiser reasonably acceptable to the Owner
Participant, and, so long as the Lien of the Lease Indenture shall not have been
terminated or discharged, the Lease Indenture Trustee to the effect that the
Facility will, after completion of rebuilding or replacement, have at least the
same value, residual value, utility and useful life as the Facility immediately
prior to the Event of Loss, assuming the Facility was then in the condition
required to have been maintained by the terms of this Facility Lease and such
rebuilding or replacement will not result in the Facility being "limited use"
property within the meaning of Rev. Proc. 75-28, 1975-1 C.B. 752 or Rev. Proc.
76-30, 1976-2 C.B. 647;

                  (d) on the date the Facility Lessee shall give notice pursuant
to Section 10.1(a) of its election to rebuild or replace the Facility in
accordance with this Section 10.3, the Facility Lessee shall demonstrate to the
reasonable satisfaction of the Owner Participant and, so long as the Lien of the
Lease Indenture shall not have been terminated or discharged, the Lease
Indenture Trustee, that it will have adequate financial resources, from
insurance proceeds or otherwise, to complete such rebuilding or replacement;

                  (e) on the date the Facility Lessee shall give notice pursuant
to Section 10.1(a) of its election to rebuild or replace the Facility in
accordance with this Section 10.3, the Facility Lessee shall deliver an
Officer's Certificate of the Facility Lessee to the effect that it reasonably
believes that it will have sufficient funds available to continue to pay
Periodic Lease Rent or Renewal Lease Rent, as the case may be, while the
Facility is being rebuilt;

                  (f) the Facility Lessee shall cause the rebuilding or
replacement of the Facility to commence as soon as practicable after notifying
the Owner Lessor 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
Trustee pursuant to Section 10.1(a), of its election to rebuild or replace the
Facility, and in all events within 24 months of the occurrence of the event that
caused such Event of Loss and will cause work on such rebuilding or replacement
to proceed diligently thereafter. As the rebuilding or replacement of the
Facility progresses, title to an undivided interest equal to the Owner Lessor's
Percentage in the rebuilt or replacement Facility shall vest in

the Owner Lessor and such undivided interest shall become subject to this
Facility Lease and, so long as the Lien of the Lease Indenture shall not have
been terminated or discharged, the Lien of the Lease Indenture and be deemed a
part of the Facility Interest for all purposes of this Facility Lease,
automatically and without any further act by any Person; and

                  (g) on the date of the completion of such rebuilding or
replacement of the Facility (the "Rebuilding Closing Date"), the following
documents shall be duly authorized, executed and delivered and, if appropriate,
filed for recordation by the respective party or parties thereto and shall be in
full force and effect, and an executed counterpart of each thereto shall be
delivered to the Owner Lessor, the Owner Participant and, so long as the Lien of
the Lease Indenture shall not have been terminated or discharged, the Lease
Indenture Trustee: (i) supplements to this Facility Lease subjecting an
undivided interest equal to the Owner Lessor's Percentage in the rebuilt or
replacement Facility to this Facility Lease (with no change in Purchase Price or
the Periodic Lease Rent or Allocated Rent or Renewal Lease Rent as a result of
such rebuilding or replacement), (ii) so long as the Lien of the Lease Indenture
shall not have been terminated or discharged, supplements to the Lease Indenture
subjecting such undivided interests in the rebuilt or replacement facilities to
the Lien of the Lease Indenture, (iii) such recordings and filings as may be
reasonably requested by the Owner Participant and so long as the Lien of the
Lease Indenture shall not have been terminated or discharged, the Lease
Indenture Trustee to be made or filed, (iv) an opinion of counsel of the
Facility Lessee, such counsel and such opinion to be reasonably satisfactory to
the Owner Participant and, so long as the Lien of the Lease Indenture shall not
have been terminated or discharged, the Lease Indenture Trustee to the effect
that (A) the supplements to this Facility Lease required by clause (i) above
constitute effective instruments for subjecting such undivided interests in the
rebuilt or replacement facilities to this Facility Lease, (B) the supplements to
the Lease Indenture required by clause (ii) above, if any, constitute effective
instruments for subjecting such undivided interests in the rebuilt or
replacement facilities to the Lien of the Lease Indenture, and (C) all filings
and other action necessary to perfect and protect the Owner Lessor's and, if
applicable, the Lease Indenture Trustee's interest in such undivided interests
in the rebuilt or replacement facilities have been accomplished, (v) an
appraisal by an Independent Appraiser, certifying that the Facility as so
rebuilt or replaced has a current and residual value, remaining useful life and
utility at least equal to the current and residual value, remaining useful life
and utility of the Facility immediately prior to the Event of Loss giving rise
to such repair or replacement (assuming the Facility was in the condition and
repair required to be maintained by the terms of this Facility Lease and such
rebuilding or replacement has not resulted in the Facility being "limited use"
property within the meaning of Rev. Proc. 75-28, 1975 C.B. 752 or Rev. Proc.
76-30, 1976-2 C.B. 647), (vi) a report by an independent engineer certifying
that such Facility as so rebuilt or replaced is in a state of repair and
condition required by this Facility Lease, (vii) an Officer's Certificate of the
Facility Lessee certifying as to compliance with this Section 10.3 and that no
Event of Default shall have occurred and be continuing as a result of the
rebuild or replacement, and (viii) satisfactory evidence as to the compliance

rebuilt or replaced.

         Whether or not the transactions contemplated by this Section 10.3 are
consummated, the Facility Lessee agrees to pay or reimburse, on an After-Tax
Basis, any costs or expenses (including reasonable legal fees and expenses)
incurred by the Owner Lessor, the Owner

Participant, the Equity Investor, the Lease Indenture Trustee and the Pass
Through Trustee in connection with the transactions contemplated by this Section
10.3.

         Section 10.4 Application of Payments Not Relating to an Event of Loss.

                  (a) In the event that during the Facility Lease Term title to,
or the use of all or any portion of, the Facility Interest is requisitioned or
taken by or pursuant to a request of any Governmental Entity under the power of
eminent domain or otherwise for a period which does not constitute an Event of
Loss, the Facility Lessee's obligation to pay all installments of Periodic Lease
Rent or Renewal Lease Rent with respect to the Facility Interest shall continue
for the duration of such requisitioning or taking. The Facility Lessee shall be
entitled to receive and retain for its own account all sums payable for any such
period by such Governmental Entity as compensation for such requisition or
taking of possession. Any amount referred to in this Section 10.4(a) which is
payable to the Facility Lessee shall not be paid to the Facility Lessee, or if
it has been previously paid directly to the Facility Lessee, shall not be
retained by the Facility Lessee, if at the time of such payment a Significant
Lease Default or Lease Event of Default shall have occurred and be continuing,
but shall be paid to and held by the Owner Lessor or, so long as the Lien of the
Lease Indenture shall not have been terminated or discharged, the Lease
Indenture Trustee as security for the obligations of the Facility Lessee under
this Facility Lease, and at such time as there shall not be continuing any such
Significant Lease Default or Lease Event of Default, such amount shall be paid
to the Facility Lessee.

                  (b) Any insurance proceeds with respect to the Facility
Interest received at any time by the Owner Lessor, the Lease Indenture Trustee
or the Facility Lessee under any of the insurance policies required to be
maintained by the Facility Lessee under Section 11 as a result of any damage to
the Facility or any part thereof which does not constitute an Event of Loss
shall be applied as follows: (i) in accordance with Section 11.7; and (ii) the
balance, if any, of such insurance proceeds remaining thereafter shall be paid
to the Facility Lessee.

                                   SECTION 11

                                    INSURANCE

         Section 11.1 Property Insurance. Subject to Section 11.6, the Facility
Lessee will maintain (or cause to be maintained) all risk property insurance
customarily carried by prudent operators of coal-fired electric generating
facilities of comparable size and risk of the Facility, and against loss or
damage from such causes as are customarily insured against, which includes
coverage for boiler and machinery coverage to cover mechanical breakdown and
business interruption and, in any case, subject to availability on commercially
reasonable terms, in an amount equal to the Facility Lessee's portion of the
Maximum Probable Loss of the Facility (as adjusted pursuant to Section 11.3(e)),
subject to a deductible, as respects the Facility Lessee's interest, not to
exceed $2,500,000 per occurrence for property damage, except $5,000,000 per
occurrence in respect of boiler and machinery coverage and a 60-day waiting
period for business interruption or such other higher amounts customarily
maintained by prudent operators of coal-fired electric generating facilities of
comparable size and risk of the Facility.

         Section 11.2 Liability Insurance. Subject to Section 11.6, the Facility
Lessee will maintain (or cause to be maintained) commercial general liability
insurance, including contractual liability coverage and sudden and accidental
pollution liability coverage, and commercial automobile liability insurance,
insuring against claims for bodily injury (including death) and property damage
to third parties arising out of the ownership, operation, maintenance, condition
and use of the Facility and the Facility Site, with limits of not less than
$50,000,000 per occurrence and in the annual aggregate scaled proportionately to
the Facility Lessee's interest with a deductible not to exceed $2,500,000 per
occurrence as respects the Facility Lessee's interest or such other higher
amount customarily maintained by prudent operators of coal-fired electric
generating facilities of comparable size and risk of the Facility. The Facility
Lessee will periodically review the liability insurance maintained by it or on
its behalf and will, if necessary, revise such coverage and limits (including
deductibles) in order that the liability insurance maintained by it or on its
behalf is consistent with that maintained by prudent operators of similar
facilities of comparable size and risk to the Facility; provided that the
Facility Lessee may not (except as permitted by Section 11.6 below) increase
deductibles above or decrease coverage or limits below the requirements set
forth herein without the written consent of the Owner Lessor, which such consent
shall not be unreasonably withheld. Such liability insurance may be purchased
either in a single limit or in combination with a general and an excess policy.

         Section 11.3 Provisions with Respect to Insurance.

                  (a) In respect of the insurance required to be maintained or
caused to be maintained by the Facility Lessee under this Section 11, the
Facility Lessee will, or will use reasonable efforts in respect of insurance
that it does not directly effect, but for which it has benefit, subject to
Section 11.6 below, (i) place the insurance maintained pursuant to this Section
11.3 with companies having an A.M. Best rating of at least "A-" or, if not so
rated, of comparable financial strength, (ii) except in the case of any
insurance issued pursuant to Section 11.1, name the Owner Lessor, the Lessor
Manager (both in its individual capacity and as manager), the Owner Participant,
the Equity Investor, the Equity Subsidiary Holding Company, the Equity
Subsidiary, the Lease Indenture Trustee and the Pass Through Trustee as
additional insureds, as their interests may appear, (iii) in the case of
insurance issued pursuant to Section 11.1, name the Owner Lessor, the Lessor
Manager (both in its individual capacity and as manager), the Owner Participant,
the Equity Investor, the Equity Subsidiary Holding Company, the Equity
Subsidiary, the Lease Indenture Trustee and the Pass Through Trustee as
additional named insured and/or loss payees, as appropriate, (iv) cause the
insurance companies to agree to waive all claims for premiums from, and all
subrogation rights against, the Owner Lessor, the Lessor Manager, the Owner
Participant, the Equity Investor, the Equity Subsidiary Holding Company, the
Equity Subsidiary, the Lease Indenture Trustee and the Pass Through Trustee, and
(v) cause such insurance to be primary without right of contribution of any
other insurance carried by or on behalf of the Owner Lessor, the Owner
Participant, the Equity Investor, the Equity Subsidiary Holding Company, the
Equity Subsidiary, the Lease Indenture Trustee and the Pass Through Trustee with
respect to their respective interests in the Facility and the Facility Site.

                  (b) The Facility Lessee will, subject to Section 11.6 below,
use its reasonable efforts to provide that the respective interests of the Owner
Lessor, the Owner Participant, the Equity Subsidiary, the Equity Subsidiary
Holding Company, the Equity Investor, the Lease

                            Conemaugh Facility Lease
                                       26

Indenture Trustee and the Pass Through Trustee shall not be invalidated by any
act or neglect of the Facility Lessee, or any breach or violation by the
Facility Lessee of any warranties, declarations or conditions contained in the
property insurance policies or by the use of the Facility for purposes more
hazardous than permitted by such policies. Additionally, the Facility Lessee
will, subject to Section 11.6 below, use its reasonable efforts to provide that
the liability insurance policies required to be maintained hereunder shall be
endorsed to provide that, inasmuch as the policies are written to cover more
than one insured, all terms, conditions, insuring agreements and endorsements,
with the exception of limits of liability, shall operate in the manner as if
there were a separate policy covering each insured. The Facility Lessee shall,
at its own expense, make or cause to be made all proofs of loss and take all
other steps necessary to collect the proceeds of such insurance.

                  (c) All of the insurance policies required by this Section 11
may cover other operations, facilities and properties of the Facility Lessee or
Reliant or its Affiliates as long as the limits of insurance available to the
Facility are not less than the requirements set forth herein.

                  (d) Claims and losses, if any, under any insurance policies
required to be carried under this Section 11 shall be adjusted with the
insurance companies, including the filing of appropriate proceedings, by,
subject to the Owners Agreement, the Facility Lessee.

                  (e) The Maximum Probable Loss will be adjusted (i) within 60
days after the close of each fiscal quarter during which the cumulative cost of
Modifications (other than Severable Modifications that are not Required
Modifications) to the Facility Interest exceeds an additional 10% of the
Purchase Price since the most recent adjustment of the Maximum Probable Loss
pursuant to this Section 11.3(e) and (ii) on each fifth anniversary of the most
recent adjustment of Maximum Probable Loss pursuant to this Section 11.3(e);
provided, that the first such adjustment shall occur no later than the fifth
anniversary of the Closing Date. Such adjustment shall be based on an analysis,
at the Facility Lessee's expense, of an independent insurance expert from a
nationally recognized insurance brokerage firm selected by the Facility Lessee
and reasonably acceptable to the Owner Lessor. As soon as practicable after any
such adjustment, the Facility Lessee shall, subject to the terms of this Section
11, cause the its property insurance policies to carry coverage of at least the
adjusted Maximum Probable Loss.

         Section 11.4 Reports. Within 10 Business Days after expiration and
renewal of any insurance policy required to be maintained pursuant to this
Section 11, the Facility Lessee shall provide the Owner Lessor, the Equity
Investor, the Owner Participant, and as long as the Lien of the Lease Indenture
shall not have been terminated or discharged, the Lease Indenture Trustee and
the Pass Through Trustee certificates from insurance brokers or carriers to the
effect that such policy is in effect and in the case of policies maintained
pursuant to Section 11.1 and 11.2, indicating their status as additional
insureds, loss payees or additional named insured as required pursuant to
Section 11.3(a). Such insurance certificates shall provide for at least 45 days'
prior written notice (10 days for non-payment of premium) to the Owner Lessor,
the Equity Investor, the Owner Participant, the Lease Indenture Trustee and the
Pass Through Trustee, in the event of cancellation, or non-renewal, by the
insurance carriers, of such policies and the procedure for payment of insurance
proceeds upon the occurrence of a Significant Lease Default or Lease Event of
Default or upon the occurrence of an Event of Loss as specified in Section 11.7.
Each year the Facility Lessee shall furnish an Officer's Certificate of the
Facility Lessee certifying that

                            Conemaugh Facility Lease
                                       27
<PAGE>   32

all premiums in respect of such policies are current and that such coverage is
in compliance with all insurance requirements set forth in this Section 11.

         Section 11.5 Additional Insurance by Owner Lessor At any time the Owner
Lessor (either directly or in the name of the Owner Participant, the Equity
Subsidiary, the Equity Subsidiary Holding Company or the Equity Investor) or the
Lease Indenture Trustee may at its own expense and for its own account carry
insurance with respect to its respective interest in the Facility Interest,
provided that such insurance does not in any way interfere with the Facility
Lessee's ability to obtain insurance with respect to the Facility Interest
described in this Section 11. Any insurance payments received from policies
maintained by the Owner Lessor, the Equity Subsidiary, the Equity Subsidiary
Holding Company, the Equity Investor or the Lease Indenture Trustee pursuant to
the previous sentence shall be retained by such Person, without reducing or
otherwise affecting the Facility Lessee's obligations hereunder.

         Section 11.6 Amendment of Requirements.

                  (a) If any insurance required to be maintained by the Facility
Lessee pursuant to this Section 11 (including the limits or deductibles or any
other terms under policies for such insurance) ceases to be available on a
commercially reasonable basis, the Facility Lessee shall provide written notice
to the Owner Lessor and, so long as the Lien of the Lease Indenture shall not
have been terminated or discharged, the Lease Indenture Trustee accompanied by a
letter from the Facility Lessee's insurance broker stating that such insurance
is unavailable on a commercially reasonable basis. Such notice shall be given
not less than thirty (30) days prior to the scheduled date for renewal of any
such policy. Upon receipt of such notice by the Owner Lessor, the Owner Lessor
and the Facility Lessee shall immediately enter into good faith negotiations in
order to obtain an alternative to such insurance.

                  (b) In the event that the Owner Lessor and the Facility Lessee
cannot reach a resolution acceptable to both parties within ten (10) days, the
Owner Lessor and the Facility Lessee shall make arrangements for the formation
of an insurance panel consisting of the Facility Lessee's insurance advisor (or
broker), the Owner Lessor's insurance advisor (or broker) and an independent
insurance expert from a nationally recognized insurance brokerage firm, chosen
by the Facility Lessee and reasonably acceptable to the Owner Lessor. Such
independent expert shall conduct a separate review of the relevant insurance
requirements of this Section 11 and the market for such insurance at the time,
giving due consideration to the representations of both insurance advisors, and
upon conclusion of such review shall issue a written report stating whether such
insurance is available or unavailable on a commercially reasonable basis.

                  (c) If the insurance expert concludes that such insurance is
not available on a commercially reasonable basis, the insurance expert shall
provide a written recommendation (which shall include the amount and type of
insurance which is available upon a commercially reasonable basis) not less than
fifteen (15) days before the date for renewal of such insurance. The Facility
Lessee shall, prior to the expiration of the insurance then in effect, obtain
the insurance required by this Section 11 that is available on a commercially
reasonable basis. If the senior unsecured long-term debt rating of the Facility
Lessee shall be rated at least BBB- by S&P and Baa3 by Moody's at the time of
renewal, the recommendation of the insurance expert shall be conclusive and
binding upon the Facility Lessee and the Facility Lessee shall, for the

                            Conemaugh Facility Lease
                                       28
<PAGE>   33

immediately succeeding one (1) year policy period, only be required to carry the
insurance required by this Section 11 that the expert has certified is available
on a commercially reasonable basis.

                  (d) If the senior unsecured long-term debt of the Facility
Lessee is below BBB- by S&P and Baa3 by Moody's at such time of renewal and in
the Owner Participant's reasonable judgment, keeping the insurance coverage at
the level that is available on a commercially reasonable basis could reasonably
be expected to result in a Material Adverse Effect or involve any material risk
of the occurrence of any material adverse effect being incurred by the Equity
Investor, the Equity Subsidiary Holding Company, the Equity Subsidiary, the
Owner Participant, the Owner Lessor, the Lessor Manager, the Lease Indenture or
the Pass Through Trustee, then the Facility Lessee shall (a) comply with this
Section 11 without regard to this Section 11.6 or (b) obtain the insurance that
is available on a commercially reasonable basis and provide collateral or credit
support for the difference of a type and in an amount satisfactory to the Owner
Participant. For the purposes of this Section 11.6, insurance will be considered
"not available on a commercially reasonable basis" if it is not obtainable or
obtainable only at excessive costs or other unreasonable terms which are not
justified in terms of the risk to be insured and is generally not being carried
by or applicable to projects or operations similar to the Facility because of
such excessive costs or other unreasonable terms.

                  (e) All reasonable fees, costs and expenses associated with
the insurance panel (including the review by the insurance expert) shall be for
the sole account of the Facility Lessee.

         Section 11.7 Application of Insurance Proceeds.

                  (a) So long as no Significant Lease Default or Lease Event of
Default shall have occurred and be continuing, all insurance proceeds with
respect to the Facility Interest on account of any damage to or destruction of
the Facility or any part thereof (in each case less the actual costs, fees and
expenses incurred in the collection thereof) other than proceeds arising out of
an Event of Loss, shall be paid to and retained by the Facility Lessee for
application in repair or replacement of the affected property or other purpose
as determined by the Facility Lessee. Promptly after receiving Actual Knowledge
that a Significant Lease Default or Lease Event of Default shall have occurred
and be continuing, the Facility Lessee shall notify the insurer under any
property insurance policy providing coverage of the Facility Interest of the
existence of such Significant Lease Default or Lease Event of Default. The
Facility Lessee shall not have the exclusive right to provide such notice to any
such insurer respecting the Facility Interest. The Owner Lessor, the Owner
Participant and, so long as the Lien of the Lease Indenture shall not have been
terminated or discharged, the Lease Indenture Trustee shall have the right, but
not the obligation, to notify the insurer under any such property insurance
policy of the occurrence of any Significant Lease Default or Lease Event of
Default. After receipt of any such notification, each such insurer shall pay the
proceeds of any property insurance policies to the Owner Lessor or, if the Lien
of the Lease Indenture shall not have been terminated or discharged, the Lease
Indenture Trustee.

                  (b) Within 30 days after receiving Actual Knowledge that an
Event of Loss has occurred, the Facility Lessee shall notify the insurer under
any property insurance policy

providing coverage for such Event of Loss, the Lease Indenture Trustee so long
as the Lien of the Lease Indenture shall not have been terminated or discharged,
and the Owner Lessor of the occurrence of such Event of Loss. Each of the
Facility Lessee, the Owner Lessor and the Lease Indenture Trustee, as
applicable, shall provide any necessary endorsements and otherwise cooperate in
the processing of any related claims or proceeds in accordance with the terms of
this Section 11.

                  (c) Any payment under any policy of insurance maintained
pursuant to this Section 11 arising out of an Event of Loss in respect of
physical damage to property shall be made jointly to the Facility Lessee and to
the Lease Indenture Trustee so long as the Lien of the Lease Indenture shall not
have been terminated or discharged, or otherwise to the Facility Lessee and the
Owner Lessor.

                  (d) All proceeds of insurance paid to the Facility Lessee and
the Lease Indenture Trustee or the Owner Lessor, as the case may be, other than
such proceeds paid in connection with an Event of Loss as to which the Facility
Lessee has elected (or has been deemed to have elected) to pay Termination Value
shall be paid over to the Facility Lessee by such Person upon (i) delivery by
the Facility Lessee to the Owner Lessor and the Lease Indenture Trustee, if
applicable, of an Officer's Certificate (a) describing in reasonable detail the
nature and cost of such repair or restoration and the actual expenditures
theretofore made in connection therewith and (b) certifying that the sum
requested is a proper item request and has been paid, or is then due and
payable, by the Facility Lessee and (ii) receipt by the Owner Lessor and the
Lease Indenture Trustee, if applicable, of evidence satisfactory to each of
them, in their reasonable judgments that such proceeds, together with funds of
the Facility Lessee available for the purposes will be sufficient to complete
such repair and restoration of the Facility Interest or portion thereof.
Proceeds of property insurance in connection with an Event of Loss as to which
the Facility Lessee has agreed to pay Termination Value pursuant to Section 10,
shall be applied by the Lease Indenture Trustee or the Owner Lessor on the
relevant Termination Date to the payment of such Termination Value.

                  (e) Notwithstanding the foregoing provisions of this Section
11 or Section 10, so long as a Significant Lease Default or Lease Event of
Default shall have occurred and be continuing, the proceeds of any insurance
required to be maintained pursuant to Section 11.1 that would otherwise be
payable to or for the account of, or that would otherwise be retained by, the
Facility Lessee pursuant to this Section 11 or Section 10.2(d) will be held as
security for the obligations of the Facility Lessee under this Facility Lease by
the Owner Lessor or, so long as the Lien of the Lease Indenture shall not have
been terminated or discharged, the Lease Indenture Trustee and, at such time
thereafter as no Significant Lease Default or Lease Event of Default shall be
continuing, such amount shall be paid promptly to the Facility Lessee.

                                   SECTION 12

                                   INSPECTION

         During the Facility Lease Term, each of the Owner Participant, the
Owner Lessor, the Equity Investor, 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 Trustee and each of their

respective representatives may, during normal business hours, on reasonable
notice to the Facility Lessee and at their own risk and expense (except, at the
expense but not risk, of the Facility Lessee when a Significant Lease Default or
a Lease Event of Default has occurred and is continuing), inspect the Facility
and the records with respect to the operations and maintenance thereof, in the
Facility Lessee's custody or to which the Facility Lessee 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 twelve-month period, and the respective
representatives of the Owner Lessor, the Owner Participant and the Equity
Investor shall coordinate such inspections so that they occur simultaneously;
provided, further, however, that any such Person may make more than one
inspection during the last eighteen months of the Facility Lease Term unless the
Facility Lessee has exercised its option under Section 15 to renew this Facility
Lease beyond such eighteen month period. Any such inspection will be conducted
in accordance with the Owners Agreement and will not unreasonably interfere with
the operation or maintenance of the Facility or the conduct by the Facility
Lessee of its business and will be in accordance with the Facility Lessee's and
the Operator's safety and insurance programs. In no event shall the Owner
Lessor, the Owner Participant, the Equity Investor, 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.

                                   SECTION 13

                    TERMINATION OPTION FOR BURDENSOME EVENTS

         Section 13.1 Election to Terminate. No later than 12 months after the
date the Facility Lessee receives notice or Actual Knowledge of either of the
events specified below, the Facility Lessee shall have the right, at its option,
upon written notice (the "Burdensome Termination Notice") to the Owner Lessor,
the Owner Participant, 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 Trustee, to terminate this Facility Lease in accordance with Section
13.2 on the Termination Date specified in such notice (which shall be a date
which is not less than 30 days nor more than 60 days after the date of such
notice) or such later Termination Date as may be necessary for the Facility
Lessee to obtain such consents and approvals required for the Facility Lessee to
comply with its obligations under this Section 13 (but in no event to exceed 12
months) if:

                  (a) as a result of change in Applicable Law, it shall have
become illegal for the Facility Lessee to continue this Facility Lease or for
the Facility Lessee to make payments under this Facility Lease or any other
Operative Document, and the transactions contemplated by the Operative Documents
cannot be restructured to comply with such change in law in a manner reasonably
acceptable to the Facility Lessee, the Owner Participant, the Owner Lessor, 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 Trustee; or

                  (b) one or more events outside the control of the Facility
Lessee or any Subsidiary thereof shall have occurred which will, or can
reasonably be expected to, give rise to an obligation by the Facility Lessee to
pay or indemnify in respect of the Tax Indemnity

                            Conemaugh Facility Lease
                                       31

Agreement or Section 10.1 or 10.2 of the Participation Agreement; provided,
however, that (i) such payment or indemnity obligation (and the underlying cost
or Tax) can be avoided in whole or in part if this Facility Lease is terminated
and the Owner Lessor sells the Owner Lessor's Interest to the Facility Lessee
and (ii) the amount of such avoided payments would exceed (on a present value
basis, discounted at the Discount Rate, compounded on an annual basis to the
date of the termination) three percent of the Purchase Price; and provided,
further, that no such termination option shall exist if the applicable
indemnitee shall waive its right to, or the Owner Participant shall arrange for
payment of (without reimbursement by the Facility Lessee or any guarantor of the
Facility Lessee, or any Affiliate of either thereof), amounts of indemnification
payments under the Tax Indemnity Agreement or Section 10.1 or 10.2 of the
Participation Agreement in excess of such amount as to cause such avoided
payments, computed in accordance with the preceding proviso, not to exceed three
percent of the Purchase Price.

If the Facility Lessee does not give the Burdensome Termination Notice within
twelve months of the date the Facility Lessee receives notice or Actual
Knowledge of an event or condition described above, the Facility Lessee shall
lose its right to terminate this Facility Lease pursuant to this Section 13.1 as
a result of such event or condition.

         Section 13.2 Solicitation of Qualifying Cash Bids; Payments Upon
Termination. In connection with the delivery of a Burdensome Termination Notice,
the Facility Lessee may, but shall be under no obligation to, make an offer,
which offer shall be open for acceptance for not less than 10 days, to purchase
the Owner Lessor's Interest on the Termination Date set forth in the Burdensome
Termination Notice for cash in an amount at least equal to the Termination Value
on such Termination Date (or such later Termination Date as permitted under
Section 13.1), on an "as is", "where is" and "with all faults" basis without any
representation, other than by the Owner Lessor that the Owner Lessor's Interest
is free of Owner Lessor's Liens and a warranty of the Owner Participant as to
the absence of Owner Participant's Liens (any such offer by the Facility Lessee,
a "Qualifying Cash Bid"). Upon receipt of a Burdensome Termination Notice, the
Owner Lessor may, but shall be under no obligation to, sell the Owner Lessor's
Interest. If the Facility Lessee makes a Qualifying Cash Bid and the Owner
Lessor accepts such offer (which acceptance shall be deemed to have occurred
unless the Owner Lessor rejects such offer in writing prior to the expiration
date of such offer), the Facility Lessee shall pay the Owner Lessor on the
Termination Date (a) the amount of such Qualifying Cash Bid plus (b) all amounts
due and payable under Section 13.3 (but shall have no obligation to pay
Termination Value). If the Owner Lessor (x) rejects a Qualifying Cash Bid from
the Facility Lessee, or (y) if no Qualifying Cash Bid is offered, elects in
writing to retain the Owner Lessor's Interest, the Facility Lessee shall pay to
the Owner Lessor on the Termination Date all amounts due and payable under
Section 13.3 (but shall have no obligation to pay Termination Value). Unless
this Facility Lease is to continue as described below, on the Termination Date
specified in the Burdensome Termination Notice (or such later Termination Date
as permitted under Section 13.1), the balance of the Lessor Section 467 Loan
Balance or the Lessee Section 467 Loan Balance (as the case may be) shall be
reduced to zero and shall be fully discharged for all purposes. Any transfer in
connection with this Section 13 shall be subject to the Owners Agreement. If,
within 10 days of the Termination Date set forth in the Burdensome Termination
Notice, the Owner Lessor does not (1) receive a Qualifying Cash Bid from the
Facility Lessee, or (2) elect in writing to retain the Owner Lessor's Interest,
this Facility Lease shall continue, the Facility Lessee shall lose its right to
terminate this Facility Lease for such burdensome event, and

                                       32
<PAGE>   37

any and all rights that the Owner Lessor had immediately prior to the receipt of
the Burdensome Termination Notice shall remain in full force and effect in all
respects.

         Section 13.3 Procedure for Exercise of Termination Option. If the
Facility Lessee shall have exercised its option to terminate the Facility Lease
under Section 13.1, on the Termination Date specified in the Burdensome
Termination Notice (or such later Termination Date as permitted under Section
13.1), the Facility Lessee shall, subject to the last sentence of Section 13.2,
pay to the Owner Lessor (a) all amounts of Supplemental Lease Rent (including
all reasonable out-of-pocket costs and expenses of the Owner Lessor, the Owner
Participant, the Lease Indenture Trustee and the Pass Through Trustee, all
sales, use, value added and other Taxes required to be indemnified by the
Facility Lessee pursuant to Section 10.2 of the Participation Agreement
associated with the exercise of the termination option pursuant to this Section
13 and all indemnity amounts) due and payable or unpaid or accrued on or prior
to the Termination Date, and (b) any other payment obligation of the Facility
Lessee under the Operative Documents (other than Periodic Lease Rent or Renewal
Lease Rent due on or after the Termination Date) due and payable or unpaid or
accrued before such Termination Date, but the Facility Lessee shall not be
required to pay Termination Value. All Rent payments under Section 13.2 and this
Section 13.3 shall, to the extent required by Section 3.6, be made to the Lease
Indenture Trustee. Concurrently with the payment of all sums specified in
Section 13.2 and this Section 13.3 (i) Periodic Lease Rent, or Renewal Lease
Rent, as the case may be, shall cease to accrue, (ii) the Facility Lessee shall
cease to have any liability to the Owner Lessor with respect to the Facility
Interest, except for Supplemental Lease Rent and other obligations (including
those under Sections 10.1 and 10.2 of the Participation Agreement and the Tax
Indemnity Agreement) surviving pursuant to the express terms of any Operative
Document, (iii) unless the Facility Lessee assumes the Notes pursuant to Section
13.4, the Owner Lessor shall pay the outstanding principal and accrued interest
on the Notes (excluding any Make Whole Premium, if any, due and payable)
pursuant to Section 2.10(a) of the Lease Indenture, (iv) this Facility Lease
shall terminate, (v) in connection with any sale of the Owner Lessor's Interest
pursuant to Section 13.2, the Owner Lessor shall transfer (by an appropriate
instrument of transfer in form and substance reasonably satisfactory to the
Owner Lessor and prepared by and at the expense of the Facility Lessee) all of
its right, title and interest in and to the Owner Lessor's Interest to the
Facility Lessee or its designee on an "as is", "where is" and "with all faults"
basis, without representations or warranties other than a warranty as to the
absence of Owner Lessor's Liens and a warranty of the Owner Participant as to
the absence of Owner Participant's Liens, and (vi) the Owner Lessor shall
execute and deliver appropriate releases and other documents or instruments
necessary or desirable to effect the foregoing, all to be prepared, filed and
recorded (as appropriate) at the cost and expense of the Facility Lessee. It
shall be a condition of the termination of this Facility Lease pursuant to this
Section 13 that the Facility Lessee shall pay all amounts it is obligated to pay
under Section 13.2 and this Section 13.3. If the Facility Lessee fails to
consummate the termination option under this Section 13 after giving notice of
its intention to do so, (A) this Facility Lease shall continue, (B) such failure
to consummate shall not constitute a default under this Facility Lease, and (C)
unless such failure is a consequence of a failure of the Owner Lessor or Owner
Participant to fulfill their obligations under this Section 13, the Facility
Lessee will lose its right to terminate this Facility Lease pursuant to this
Section 13 as a result of such event or condition during the remainder of the
Facility Lease Term, but the Facility Lessee shall in any event (without
relieving the Owner Lessor of any liability hereunder) pay the amounts set forth
in clause (a) above. Anything to the

<PAGE>   38

contrary in this Section 13 notwithstanding, the Facility Lessee and the Owner
Lessor agree for the benefit of the Lease Indenture Trustee (without relieving
the Owner Lessor of any liability hereunder) that, so long as the Lien of the
Lease Indenture shall not have been terminated or discharged, no termination
pursuant to this Section 13 shall be effective (regardless of whether the Owner
Lessor shall elect to retain or sell the Facility Interest in connection with
such proposed termination) unless and until the Facility Lessee shall have
assumed the Notes pursuant to Section 13.4 or the Owner Lessor shall have paid
all outstanding principal and accrued interest on the Notes and all other
amounts due under the Lease Indenture on the proposed Termination Date.

         Section 13.4 Assumption of the Notes. Notwithstanding the foregoing
provisions of Section 13.2 (except for the provision relating to the reduction
and discharge of the Lessor Section 467 Loan Balance or the Lessee Section 467
Loan Balance), if (a) the Facility Lessee submits a Qualifying Cash Bid, and the
Owner Lessor accepts such Qualifying Cash Bid and the Facility Lessee shall
purchase the Facility Interest pursuant to this Section 13, (b) the Facility
Lessee shall have executed and delivered an assumption agreement to assume the
Notes as permitted by and in accordance with Section 2.10(b) of the Lease
Indenture, (c) all other conditions contained in such Section 2.10(b) shall have
been satisfied, and (d) no Significant Lease Default or Lease Event of Default
shall have occurred and be continuing after giving effect to such assumption,
then (x) the obligation of the Facility Lessee to pay the purchase price set
forth in its Qualifying Cash Bid shall be satisfied to the extent the
outstanding principal amount of and accrued interest on the Notes is so assumed
by the Facility Lessee and (y) the Owner Lessor shall have no further obligation
to prepay the outstanding principal and accrued interest on the Notes.

                                   SECTION 14

           TERMINATION FOR OBSOLESCENCE; PARTIAL RELEASE OF INTERESTS

         Section 14.1 Termination. Upon at least six months' prior written
notice to the Owner Lessor, the Owner Participant and, so long as the Lien of
the Lease Indenture has not been terminated or discharged, the Lease Indenture
Trustee and the Pass Through Trustee (which notice shall be accompanied by a
certification by the management committee or other governing body of the
Facility Lessee as to one or more of the matters described in clause (a) and (b)
below and an Officer's Certificate setting forth in reasonable detail the basis
on which it is exercising this termination option), the Facility Lessee shall
have the option, so long as no Lease Event of Default shall have occurred and be
continuing, to terminate this Facility Lease with respect to the Facility
Interest on any Termination Date occurring on or after the sixth anniversary of
the Closing Date (the date of termination selected by the Facility Lessee being
the "Obsolescence Termination Date") which proposed Obsolescence Termination
Date shall be set forth in the notice on the terms and conditions set forth in
this Section 14 if:

                  (a) the Facility Interest is economically or technologically
         obsolete, as a result of (i) a change in Applicable Law, regulation or
         tariff of general application, or (ii) imposition by the FERC or any
         other Governmental Entity having or claiming jurisdiction over the
         Facility Lessee or the Facility Interest of any conditions or
         requirements (including, without limitation, requiring significant
         capital improvements to

                            Conemaugh Facility Lease

<PAGE>   39

         the Facility) upon the availability, continued effectiveness or renewal
         of any Governmental Approval required for the ownership or operation of
         the Facility Interest; or

                  (b) the Facility Interest is otherwise economically or
         technologically obsolete or the Facility Interest is surplus to the
         Facility Lessee's needs or is no longer useful in its trade or
         business, as determined by the management committee or other governing
         body of the Facility Lessee in good faith, including, without
         limitation, as a result of (x) a change in the markets for the
         wholesale purchase and/or sale of energy or (y) any material abrogation
         of power purchase or sale agreements or any other reason.

         Section 14.2 Solicitation of Offers. If the Facility Lessee shall give
the Owner Lessor notice pursuant to Section 14.1 and the Owner Lessor shall not
have elected to retain the Owner Lessor's Interest pursuant to Section 14.3, the
Facility Lessee shall, (i) as non-exclusive agent for the Owner Lessor, use
commercially reasonable efforts to obtain bids from third parties which are not
Affiliates of the Facility Lessee and subject (to the extent applicable to such
transfer) to any right of first refusal contained in the Owner Agreements, sell
the Owner Lessor's Interest on the Obsolescence Termination Date, and (ii)
covenant that it will not sell the Owner Lessor's Interest to itself or an
Affiliate or any third party with whom the Facility Lessee or an Affiliate
thereof has an arrangement to use or operate the Facility Interest to generate
power for the benefit of the Facility Lessee or any Affiliate thereof after the
termination of this Facility Lease. All of the proceeds of any such sale will be
for the account of the Owner Lessor; provided that so long as the Lien of the
Lease Indenture shall not have been terminated or discharged, the proceeds of
such sale shall be paid directly to the Lease Indenture Trustee. The Owner
Lessor shall also have the right but not the obligation, to obtain bids for the
sale of such Owner Lessor's Interest either directly or through agents other
than the Facility Lessee. At least 120 days prior to the Obsolescence
Termination Date, the Facility Lessee shall certify to the Owner Lessor and the
Lease Indenture Trustee each bid or offer, the amount and terms thereof and the
name and address of the party (which shall not be the Facility Lessee, any
Affiliate or any third party with whom it or an Affiliate has an arrangement to
use or operate the Facility to generate power for the benefit of the Facility
Lessee or such Affiliate after the termination of this Facility Lease with
respect to the Facility Interest) submitting such bid or offer.

         Section 14.3 Right of Owner Lessor to Retain the Owner Lessor's
Interest. The Owner Lessor may irrevocably elect to retain, rather than sell,
the Owner Lessor's Interest by giving notice to the Facility Lessee at least 90
days prior to the Obsolescence Termination Date. If the Owner Lessor elects to
retain such Owner Lessor's Interest pursuant to this Section 14.3, on the
Obsolescence Termination Date the Facility Lessee shall pay to the Owner Lessor
(a) all Supplemental Lease Rent (including all reasonable out-of-pocket costs
and expenses of the Owner Lessor, the Owner Participant, the Lease Indenture
Trustee and the Pass Through Trustee (excluding the fees and costs of any broker
unless engaged by the Facility Lessee on the Owner Lessor's behalf) and all
sales, use, value added and other Taxes required to be indemnified by the
Facility Lessee pursuant to Section 10.2 of the Participation Agreement
associated with the exercise of the termination option pursuant to this Section
14.3 due and payable on such Obsolescence Termination Date) and (b) any other
payment obligation of the Facility Lessee under the Operative Documents (other
than Periodic Lease Rent or Renewal Lease Rent due on or after but not before
the Obsolescence Termination Date) due and unpaid on the Obsolescence

Termination Date and any amounts due and unpaid or unpaid or accrued on the
Obsolescence Termination Date under any other Operative Document, but shall not
be required to pay Termination Value with respect to the Facility Interest.
Unless this Facility Lease continues pursuant to Section 14.5, on the
Obsolescence Termination Date, the balance of the Lessor Section 467 Loan
Balance or the Lessee Section 467 Loan Balance (as the case may be) shall be
reduced to zero and shall be fully discharged for all purposes. Concurrently
with the payment of all sums required to be paid pursuant to this Section 14.3,
(i) Periodic Lease Rent or Renewal Lease Rent, as the case may be, shall cease
to accrue, (ii) the Facility Lessee's obligations under Sections 6, 7, 8, 11 and
12 shall terminate, (iii) the Facility Lessee shall cease to have any other
liability hereunder to the Owner Lessor, except for Supplemental Lease Rent and
other obligations (including those under Sections 10.1 and 10.2 of the
Participation Agreement and the Tax Indemnity Agreement) surviving pursuant to
the express terms of any Operative Document, (iv) the Owner Lessor shall pay the
outstanding principal and accrued interest on the Notes pursuant to Section
2.10(a) of the Lease Indenture, (v) this Facility Lease shall terminate, (vi)
the Facility Lessee will return the Owner Lessor's Interest to the Owner Lessor
in accordance with Section 5.1, and (vii) the Owner Lessor shall execute and
deliver appropriate releases and other documents or instruments necessary or
desirable to effect the foregoing, all to be prepaid, filed and recorded (as
appropriate) at the cost and expense of the Facility Lessee. It shall be a
condition to the termination of this Facility Lease pursuant to this Section
14.3 that the Facility Lessee shall pay all amounts that it is obligated to pay
under this Section 14.3.

         Section 14.4 Procedure for Exercise of Termination Option. If the Owner
Lessor has not elected to retain the Owner Lessor's Interest with respect to the
Facility Interest in accordance with Section 14.3 , on the Obsolescence
Termination Date the Owner Lessor shall sell the Owner Lessor's Interest to the
bidder or bidders (which shall not be the Facility Lessee, an Affiliate thereof
or any third party with whom the Facility Lessee or an Affiliate thereof has an
arrangement to use or operate the Facility Interest to generate power for the
benefit of the Facility Lessee or any such Affiliate after the termination of
this Facility Lease), that shall have submitted the highest cash bid or bids
with respect to the Owner Lessor's Interest, and the Facility Lessee shall
certify to the Owner Lessor, the Owner Participant and, so long as the Lien of
the Lease Indenture shall not have been terminated or discharged, the Lease
Indenture Trustee that such buyer is not the Facility Lessee, any Affiliate
thereof or any third party with whom it or an Affiliate has an arrangement to
use or operate the Facility to generate power for the benefit of the Facility
Lessee or such Affiliate after the termination of this Facility Lease. On the
Obsolescence Termination Date, the Facility Lessee shall pay to the Owner Lessor
(a) the excess, if any, of Termination Value determined as of such Obsolescence
Termination Date over the proceeds from the sale of the Owner Lessor's Interest
paid to or retained by the Owner Lessor, (b) any other payment obligation of the
Facility Lessee under the Operative Documents (other than Periodic Lease Rent or
Renewal Lease Rent due on or after, but not before, the Obsolescence Termination
Date) due and unpaid or accrued and unpaid on the Obsolescence Termination Date
and any amounts due and unpaid on the Obsolescence Termination Date under any
Operative Document, (c) all amounts of Supplemental Lease Rent (including all
reasonable out-of-pocket costs and expenses of the Owner Lessor, the Owner
Participant, the Lease Indenture Trustee and the Pass Through Trustee (excluding
the fees and costs of any broker unless engaged by the Facility Lessee on the
Owner Lessor's behalf) and all sales, use, value added and other Taxes required
to be indemnified by the Facility Lessee pursuant to Section 10.2 of the
Participation Agreement) due and payable on such Obsolescence Termination Date,
plus

<PAGE>   41

(d) any premium due on the Notes. Unless this Facility Lease continues pursuant
to Section 14.5, on the Obsolescence Termination Date, the balance of the Lessor
Section 467 Loan Balance or the Lessee Section 467 Loan Balance (as the case may
be) shall be reduced to zero and shall be fully discharged for all purposes.
Concurrently with the payment of all sums required to be paid pursuant to this
Section 14.4, (i) Periodic Lease Rent or Renewal Lease Rent, as the case may be,
shall cease to accrue, (ii) the Facility Lessee's obligations under Sections 6,
7, 8, 11 and 12 shall terminate, (iii) the Facility Lessee shall cease to have
any other liability hereunder to the Owner Lessor, except for Supplemental Lease
Rent and other obligations (including Sections 10.1 and 10.2 of the
Participation Agreement and the Tax Indemnity Agreement) surviving pursuant to
the express terms of any Operative Document, (iv) the Owner Lessor will pay the
outstanding principal and accrued interest on the Notes (but excluding any Make
Whole Premium) pursuant to Section 2.10 of the Lease Indenture, (v) this
Facility Lease shall terminate, (vi) the Owner Lessor will transfer (by an
appropriate instrument of transfer in form and substance reasonably satisfactory
to the Owner Lessor and prepared and recorded by and at the expense of the
Facility Lessee) the Owner Lessor's Interest under this Section 14.4, to the
purchaser on an "as is", "where is" and "with all faults" basis, without
representations or warranties other than a warranty as to the absence of Owner
Lessor's Liens and a warranty from the Owner Participant as to the absence of
Owner Participant's Liens, and (vii) the Owner Lessor shall execute and deliver
appropriate releases and other documents or instruments necessary or desirable
to effect the foregoing, all to be prepaid, filed and recorded (as appropriate)
at the cost and expense of the Facility Lessee. Unless the Owner Lessor shall
have elected to retain the Owner Lessor's Interest pursuant to Section 14.3 or
the Owner Lessor with the consent of the Facility Lessee shall have entered into
a legally binding contract to sell the Owner Lessor's Interest, the Facility
Lessee may, at its election, revoke its notice of termination on at least 30
days' prior notice to the Owner Lessor, the Owner Participant 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 Trustee in which event this
Facility Lease shall continue with respect to the Facility Interest; provided,
however, that the Facility Lessee shall not be permitted to re-initiate a notice
to terminate pursuant to Section 14.1 more than once in any five year period.
The Owner Lessor shall be under no duty to solicit bids, to inquire into the
efforts of the Facility Lessee to obtain bids or otherwise take any action in
arranging any such sale of the Owner Lessor's Interest other than, if the Owner
Lessor has not elected to retain the Owner Lessor's Interest, to transfer the
Owner Lessor's Interest in accordance with clause (vi) of this Section 14.4. It
shall be a condition of the Owner Lessor's obligation to consummate a sale of
the Owner Lessor's Interest that the Facility Lessee shall pay all amounts it is
obligated to pay under this Section 14.4. If no sale shall occur on the
Obsolescence Termination Date, the notice of termination shall be deemed revoked
and this Facility Lease shall continue with respect to the Facility Interest in
full force and effect in accordance with its terms (without prejudice to the
Facility Lessee's right to exercise its rights under this Section 14).

         Section 14.5 Certain Conditions to Termination. Anything to the
contrary in this Section 14 notwithstanding, the Facility Lessee and the Owner
Lessor agree for the benefit of the Lease Indenture Trustee (without relieving
the Owner Lessor of any liability hereunder) that, so long as the Lien of the
Lease Indenture shall not have been terminated or discharged, no termination
pursuant to this Section 14 shall be effective and the Facility Lessee's rights
and obligations under this Facility Lease shall remain in full force and effect
in all respects (regardless of whether the Owner Lessor shall elect to retain or
sell the Owner Lessor's Interest

in connection with such proposed termination) unless and until the Owner Lessor
shall have paid all outstanding principal and accrued interest on the Notes and
all other amounts due under the Lease Indenture as of such proposed date of
termination, excluding any Make Whole Premium.

         Section 14.6 Partial Release of Interest; Further Assurances The
Facility Lessee shall be entitled to obtain a release of a portion of the
Facility Site or Facility Interest (the "Released Interest") in the event that
the Facility Lessee shall have delivered to the Owner Lessor and the Owner
Participant (i) a certificate of the Engineering Consultant certifying that (A)
the Released Interest (taking into account any Released Interest Related Rights)
is not necessary for the operation of the Facility in accordance with Prudent
Industry Practice and (B) the release of the Released Interest (taking into
account any Released Interest Related Rights) will not diminish the current
value, residual value, utility or remaining useful life of the Facility by more
than a de minimis amount, and (ii) an Officer's Certificate of the Facility
Lessee certifying that (x) the release of the Released Interest (taking into
account any Released Interest Related Rights) will not cause the Facility to
become "limited use" property, within the meaning of Rev. Proc. 75-28, 1975-1
C.B. 752 or Rev. Proc. 76-30, 1976-2 C.B. 647 and (y) no Significant Lease
Default or Lease Event of Default has occurred and is continuing.

                  (b) In addition, the Facility Lessee shall be entitled to
obtain a release of a portion of the Facility Interest that is obsolete or not
necessary or useful in the operation of the Facility Interest in accordance with
Prudent Industry Practice (the "Surplus Released Interest") in the event that
the Facility Lessee shall have delivered to the Owner Lessor and the Owner
Participant a certificate of the Facility Lessee certifying that the Surplus
Released Interest is surplus or obsolete and not necessary for the operation of
the Facility in accordance with Prudent Industry Practice and such Surplus
Released Interest will be scrapped.

                  (c) Subject to Section 14.6(a), with respect to any Released
Interest, the Owner Lessor shall execute and deliver and take such other action
as the Facility Lessee may reasonably request to grant to the Facility Lessee or
its designee, easements, appurtances, covenants, and other similar rights and
interests as the Facility Lessee may reasonably request in connection with any
ownership, maintenance, subdivision or operation of any Released Interest or
improvements or operations located on or in respect of such Released Interest
(the "Released Interest Related Rights"); provided that no such Released
Interest Related Rights shall materially and adversely affect the Equity
Investor, the Equity Subsidiary Holding Company, the Equity Subsidiary, the
Owner Participant, the Owner Lessor or the Lease Indenture Trustee or any of
their Affiliates.

                  (d) In connection therewith, the Owner Lessor and the Owner
Participant shall execute and deliver, at the sole cost and expense of the
Facility Lessee, such releases, discharges, conveyances and other documents as
may be reasonably requested by the Facility Lessee to effect such release and to
convey and transfer title to such Released Interest or Surplus Released Interest
to the Facility Lessee.

of the Site Lease and Sublease). Unless the Facility Lessee shall have
irrevocably elected to renew this Facility Lease for a Wintergreen Renewal Lease
Term pursuant to Sections 15.1 or 15.2 (it being understood that the exercise by
the Facility Lessee of its right to renew this Facility Lease at the end of the
Basic Lease Term or at the end of the First Wintergreen Renewal Lease Term
pursuant to Sections 15.1 or 15.2, respectively, shall not impair its right to
renew this Facility Lease at any time thereafter pursuant to this Section 15.3),

Default shall have occurred and be continuing on any such notice date or on the

Renewal Lease Term shall be equal to the lesser of (i) the Fair Market Rental
Value of the Facility Interest (as determined, in the case of the First
Wintergreen Renewal Lease Term, not more

                            Conemaugh Facility Lease

than 36 months prior to the end of the Basic Lease Term, and in the case of the
Second Wintergreen Renewal Lease Term, not more than 36 months prior to the end
of the First Wintergreen Renewal Lease Term), and (ii) 50% of the average
Periodic Lease Rent during the Basic Lease Term. The average Periodic Lease Rent
during the Basic Lease Term shall be determined without regard to: (x) any
amount attributable to adjustments to Periodic Lease Rent pursuant to Section
3.5(a)(i), (y) unless the applicable Modifications were financed by an
Additional Equity Investment, Section 3.5(a)(ii), and (z) any Additional Amounts
attributable to alternative rent schedules instituted pursuant to Section
3.5(b).

                  (b) Renewal Lease Rent payable on each Rent Payment Date
during the initial FMV Renewal Lease Term shall be equal to 101% of the Fair
Market Rental Value of the Facility Interest determined not more than 36 months
prior to the commencement of such FMV Renewal Lease Term; provided, however,
that if, on or prior to the commencement of any FMV Renewal Lease Term, the
Owner Lessor and the Facility Lessee agree or, in the absence of such agreement,
if the Facility Lessee shall provide the Owner Participant with an opinion of
counsel reasonably satisfactory to the Owner Participant (as to matters of form,
substance and authorship) or with a private letter ruling, in each case to the
effect that the Renewal Lease Rent for a FMV Renewal Lease Term may be set at
the Fair Market Rental Value without resulting in adverse Federal income tax
consequences to the Owner Participant under Section 467 of the Code, the Renewal
Lease Rent for the remainder of any current and for any subsequent FMV Renewal
Lease Term will be equal to 100% of the Fair Market Rental Value of the Facility
Interest.

         Section 15.5 Determination of Fair Market Rental Value. The Fair Market
Rental Value of the Facility Interest as of the commencement of any Renewal
Lease Term shall be determined by agreement of the Owner Lessor and the Facility
Lessee within six months after receipt by the Owner Lessor of the tentative
notice from the Facility Lessee of its election to renew pursuant to Section
15.1, 15.2 or 15.3 (but not more than 36 months before the commencement of such
Renewal Lease Term) or, if they shall fail to agree within such six month
period, shall be determined by an appraisal conducted pursuant to the Appraisal
Procedure by an Independent Appraiser. The appraiser's fees and expenses shall
be borne by the Facility Lessee.

         Section 15.6 Termination Value During Renewal Lease Terms. The amounts
which are payable during any Renewal Lease Term in respect of Termination Value
shall be determined on the basis of the Fair Market Sales Value of the Facility
Interest as of the commencement of such Renewal Lease Term, amortized on a
straight-line basis over such Renewal Lease Term to the projected Fair Market
Sales Value of the Facility as of the expiration of such Renewal Lease Term, as
such Fair Market Sales Value in each case is determined prior to the
commencement of such Renewal Lease Term, plus any amount of Renewal Lease Rent
accrued and unpaid to the date of termination. In determining Fair Market Sales
Value for any Renewal Lease Term, effect shall be given to the encumbrance on
the Facility Interest of any Renewal Lease Term available or in force.

                                EVENTS OF DEFAULT

         The following events shall constitute a "Lease Event of Default"
hereunder (whether any such event shall be voluntary or involuntary or come
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 Entity):

                  (a) the Facility Lessee shall fail to make any payment of
Periodic Lease Rent, Renewal Lease Rent or Termination Value after the same
shall have become due and such failure shall have continued (taking into account
application of the proceeds of any Qualifying Credit Support) for five (5)
Business Days after the same shall have become due; or

                  (b) the Facility Lessee shall fail to make any other payment
under the Operative Documents, including any payment of Supplemental Lease Rent
(other than Excepted Payments, unless the Owner Participant shall have declared
a default with respect thereto, or Termination Value) after the same shall have
become due and such failure shall have continued unremedied for a period of 30
days after receipt by the Facility Lessee of written notice of such failure from
the Owner Participant, the Owner Lessor, the Lease Indenture Trustee or the Pass
Through Trustee; or

                  (c) the Facility Lessee shall fail to observe or perform its
obligation to maintain (or cause to be maintained) insurance in the amounts and
on the terms set forth in Section 11; or

                  (d) the Facility Lessee or any Subsidiary Guarantor (or any
other guarantor of the Facility Lessee's obligations hereunder) shall fail to
perform or observe any covenant, obligation or agreement to be performed or
observed by it (or such guarantor) under this Facility Lease or any other
Operative Document (other than any covenant, obligation or agreement contained
in the Tax Indemnity Agreement or any covenant, obligation or agreement referred
to in clauses (a), (b), (c), (e), (k), (l) or (p) of this Section 16) in any
material respect, which failure shall continue unremedied for 30 days after
receipt by the Facility Lessee of written notice thereof from the Owner
Participant, the Owner Lessor, the Lease Indenture Trustee or any Pass Through
Trustee; provided, however, that if such condition cannot be remedied within
such 30-day period, then the period within which to remedy such condition shall
be extended up to an additional 180 days, so long as the Facility Lessee
diligently pursues such remedy and such condition is reasonably capable of being
remedied within such additional 180-day period and the continuation of such
failure during the period of such extension would not have a Material Adverse
Effect; provided, further, that in the case of the Facility Lessee's obligation
set forth in clause (a)(ii) of Section 7.1, if, to the extent and for so long as
a test, challenge, appeal or proceeding shall be prosecuted in good faith by the
Facility Lessee, the failure by the Facility Lessee to comply with such
requirement shall not constitute a Lease Event of Default if such test,
challenge, appeal or proceeding shall not involve any (i) danger of foreclosure,
sale, forfeiture or loss of any part of the Facility Interest or the impairment
of the use, operation or maintenance of the Facility in any material respect,
(ii) risk of criminal liability asserted against the Owner Lessor, the Owner
Participant, the Equity Subsidiary Holding Company, the Equity Subsidiary, the
Equity Investor or any of their respective Affiliates, or (iii) material risk of
the occurrence of any material adverse effect being incurred by the Owner
Participant, the Owner Lessor, the Equity Subsidiary, the Equity

Subsidiary Holding Company, the Equity Investor, the Lease Indenture Trustee or
the Pass Through Trustee including, without limitation, subjecting the Owner
Participant or the Owner Lessor to regulation as a public utility under
Applicable Law; and provided, further, that in the case of the Facility Lessee's
obligation set forth in clause (a)(ii) of Section 7.1, if the noncompliance is
not a type that can be immediately remedied, the failure to comply shall not be
a Lease Event of Default if the Facility Lessee is taking all reasonable action
to remedy such noncompliance and if, but only if, such noncompliance shall not
involve any danger described in clause (i), (ii) or (iii) of the preceding
proviso; and provided, further, such noncompliance, or such test, challenge,
appeal or proceeding to review shall not extend beyond the date 36 months prior
to the scheduled expiration of the Basic Lease Term or any Renewal Lease Term
then in effect or elected by the Facility Lessee; or

                  (e) to the extent such covenants are in effect, the Facility

set forth in Sections 5.3, 5.4, 5.5, 5.6, to the extent such covenant relates to
liens in respect of borrowed money, 5.7, or 5.12 of the Participation Agreement,
so long as such covenants remain in effect, in each case, within 30 days after
the occurrence thereof; or

                  (f) any representation or warranty made by the Facility Lessee
or any Subsidiary Guarantor in the Operative Documents (other than a Tax
Representation) or in the certificate delivered by the Facility Lessee at the
Closing pursuant to Section 4.1(g) of the Participation Agreement shall prove to
have been incorrect in any material respect when made and continues to be
material and unremedied for a period of 30 days after receipt by the Facility
Lessee of written notice thereof; provided, however, that if such condition
cannot be remedied within such 30-day period, then the period within which to
remedy such condition shall be extended up to an additional 120 days, so long as
the Facility Lessee diligently pursues such remedy and such condition is
reasonably capable of being remedied within such additional 120-day period, and
the continuation of such condition during the period of such extension would not
have a Material Adverse Effect; or

                  (g) the Facility Lessee or any Subsidiary Guarantor that is a
Significant Subsidiary shall (i) commence a voluntary case or other proceeding
seeking relief under the Bankruptcy Code or liquidation, reorganization or other

         Section 17.1 Remedies for Lease Event of Default. Upon the occurrence
of any Lease Event of Default and at any time thereafter so long as the same
shall be continuing, the Owner Lessor may, at its option, declare this Facility
Lease to be in default by written notice to the Facility Lessee (provided that
upon the occurrence of a Lease Event of Default described in paragraph (g) or
(h) of Section 16, this Facility Lease shall automatically be deemed to be in
default without the need for giving any notice) and at any time thereafter, so
long as the Facility Lessee shall not have remedied all outstanding Lease Events
of Default, the Owner Lessor may do one or more of the following as the Owner
Lessor in its sole discretion shall elect, to the extent permitted by, and
subject to compliance with any mandatory requirements of, Applicable Law then in
effect:

                  (a) proceed by appropriate court action or actions, either at
law or in equity, to enforce performance by the Facility Lessee at the Facility
Lessee's sole cost and expense, of the applicable covenants and terms of this
Facility Lease or to recover damages for breach thereof;

                  (b) by notice in writing to the Facility Lessee, terminate
this Facility Lease whereupon all right of the Facility Lessee to the possession
and use of the Facility Interest under this Facility Lease shall absolutely
cease and terminate but the Facility Lessee shall remain liable as hereinafter
provided; and thereupon, the Owner Lessor may demand that the Facility Lessee,
and the Facility Lessee shall, upon written demand of the Owner Lessor and at
the Facility Lessee's expense, forthwith return possession of the Facility
Interest to the Owner Lessor, in the manner and condition required by, and
otherwise in accordance with all of the provisions of Section 5 except those
provisions relating to periods of notice; and the Owner Lessor may thenceforth
hold, possess and enjoy the same free from any right of the Facility Lessee, or
its successor or assigns, to use the Facility Interest for any purpose whatever
and on the date of such termination, the balance of the Lessor Section 467 Loan
Balance or the Lessee Section 467 Loan Balance (as the case may be) shall be
reduced to zero and shall be fully discharged for all purposes;

                  (c) sell the Owner Lessor's Interest at public or private
sale, as the Owner Lessor may determine, free and clear of any rights of the
Facility Lessee under this Facility Lease and without any duty to account to the
Facility Lessee with respect to such sale or for the proceeds thereof (except to
the extent required by paragraph (f) below if the Owner Lessor elects to
exercise its rights under said paragraph and by Applicable Law), in which event
the Facility Lessee's obligation to pay Periodic Lease Rent or Renewal Lease
Rent hereunder due for any periods subsequent to the date of such sale shall
terminate (except to the extent that Periodic Lease Rent or Renewal Lease Rent
is to be included in computations under paragraph (e) or (f) below if the Owner
Lessor elects to exercise its rights under said paragraphs), and on the date of
such sale, the balance of the Lessor Section 467 Loan Balance or the Lessee
Section 467 Loan Balance (as the case may be) shall be reduced to zero and shall
be fully discharged for all purposes;

                  (d) hold, keep idle or lease to others the Owner Lessor's
Interest as the Owner Lessor in its sole discretion may determine, free and
clear of any rights of the Facility Lessee under this Facility Lease and without
any duty to account to the Facility Lessee with respect to such action or
inaction or for any proceeds with respect thereto, except that the Facility
Lessee's obligation to pay Periodic Lease Rent or Renewal Lease Rent with
respect to the Facility Interest due for any periods subsequent to the date upon
which the Facility Lessee shall have been deprived of possession and use of the
Facility Interest pursuant to this Section 17 shall be reduced by the net
proceeds, if any, received by the Owner Lessor from leasing the Facility
Interest to any Person other than the Facility Lessee;

                  (e) whether or not the Owner Lessor shall have exercised, or
shall thereafter at any time exercise, any of its rights under paragraph (b)
above with respect to the Facility Interest, the Owner Lessor, by written notice
to the Facility Lessee specifying a Termination Date that shall be not earlier
than 10 days after the date of such notice, may demand that the Facility Lessee
pay to the Owner Lessor, and the Facility Lessee shall pay to the Owner Lessor,
on the Termination Date specified in such notice, any due and unpaid or accrued
and unpaid Periodic Lease Rent or Renewal Lease Rent due before the Termination
Date, any Supplemental Lease Rent due and payable as of the payment date
specified in such notice, plus as liquidated damages for loss of a bargain and
not as a penalty (in lieu of the Periodic Lease Rent or Renewal Lease Rent due
for any periods subsequent to the date of such sale), (i) an amount equal to the
excess, if any, of the Termination Value computed as of the Termination Date
specified in such notice over the Fair Market Sales Value of the Owner Lessor's
Interest as of the Termination Date specified in such notice, or (ii) an amount
equal to the excess, if any, of Termination Value computed as of the Termination
Date specified in such notice over the Fair Market Rental Value of the Owner
Lessor's Interest until the end of the Basic Lease Term or the then current
Renewal Lease Term, after discounting such Fair Market Rental Value semiannually
to present value as of the Termination Date specified in such notice at a rate
equal to the Lease Debt Rate, or (iii) an amount equal to the Termination Value
computed as of the Termination Date specified in such notice and, upon payment
of such Termination Value by the Facility Lessee pursuant to the clause (iii)
and all other Rent then due and unpaid or accrued and unpaid by the Facility
Lessee, the Owner Lessor will forthwith transfer to the Facility Lessee (or its
designee) in accordance with this Section 17.1(e) on an "as is", "where is" and
"with all faults" basis, without representation or warranty other than a
warranty as to the absence of Owner Lessor's Liens accompanied by a warranty of
the Owner Participant as to the absence of Owner Participant's Liens, all of its
interest in the Owner Lessor's Interest and execute, acknowledge and deliver,
and record and file (as appropriate) appropriate releases, including a release
of the Lien of the Lease Indenture, and all other documents or instructions
necessary or desirable to effect the foregoing all in form and substance
reasonably satisfactory to the Owner Lessor and at the cost and expense of the
Facility Lessee, and upon payment of such amounts under either clauses (i) and
(ii) of this paragraph (e), this Facility Lease, and the Facility Lessee's
obligation to pay Periodic Lease Rent or Renewal Lease Rent hereunder due for
any periods subsequent to the date of such payment shall terminate; provided
that on the Termination Date specified above, the balance of the Lessor Section
467 Loan Balance or the Lessee Section 467 Loan Balance (as the case may be)
shall be reduced to zero and shall be fully discharged for all purposes; and

                  (f) if the Owner Lessor shall have sold the Owner Lessor's
Interest pursuant to paragraph (c) above, the Owner Lessor may, if it shall so
elect, demand that the Facility

Lessee pay to the Owner Lessor, and the Facility Lessee shall pay to the Owner
Lessor, as liquidated damages for loss of a bargain and not as a penalty (in
lieu of the Periodic Lease Rent or Renewal Lease Rent due for any periods
subsequent to the date of such sale), an amount equal to (i) any unpaid Periodic
Lease Rent or Renewal Lease Rent due or accrued and unpaid before the date of
such sale, plus (ii) the amount, if any, by which Termination Value computed as
of the Termination Date next preceding the date of such sale or, if such sale
occurs on a Rent Payment Date or a Termination Date then computed as of such
date, exceeds the net proceeds of such sale, and, upon payment of such amount,
this Facility Lease and the Facility Lessee's obligation to pay Periodic Lease
Rent or Renewal Lease Rent for any periods subsequent to the date of such
payment shall terminate.

         In addition, the Facility Lessee shall be liable, except as otherwise
provided above, for (i) any and all unpaid Periodic Lease Rent or Renewal Lease
Rent due hereunder before or during the exercise of any of the foregoing
remedies, (ii) in the case of a Lease Event of Default described in Section
16(j), any Change of Control Premium payable under Section 4.2(a) of the Lease
Indenture, and (iii) on an After-Tax Basis, for legal fees and other costs and
expenses incurred by reason of the occurrence of any Lease Event of Default or
the exercise of the Owner Lessor's remedies with respect thereto, including the
repayment in full of any costs and expenses necessary to be expended in
connection with the return of the Facility Interest in accordance with Section
5, including, any costs and expenses incurred by the Owner Lessor, the Owner
Participant, the Lease Indenture Trustee or the Pass Through Trustee in
connection with retaking constructive possession of, or in repairing, the
Facility Interest in order to cause it to be in compliance with all maintenance
standards imposed by this Facility Lease.

         Section 17.2 Cumulative Remedies. The remedies in this Facility Lease
provided in favor of the Owner Lessor shall not be deemed exclusive, but shall
be cumulative and shall be in addition to all other remedies in its favor
existing at law or in equity; and the exercise or beginning of exercise by the
Owner Lessor of any one or more of such remedies shall not preclude the
simultaneous or later exercise by the Owner Lessor of any or all of such other
remedies. To the extent permitted by Applicable Law, the Facility Lessee hereby
waives any rights now or hereafter conferred by statute or otherwise which may
require the Owner Lessor to sell, lease or otherwise use the Facility Interest
or any Component thereof in mitigation of the Owner Lessor's damages as set
forth in this Section 17 or which may otherwise limit or modify any of the Owner
Lessor's rights and remedies in this Section 17.

         Section 17.3 No Delay or Omission to be Construed as Waiver. No delay
or omission to exercise any right, power or remedy accruing to the Owner Lessor
upon any breach or default by the Facility Lessee under this Facility Lease
shall impair any such right, power or remedy of the Owner Lessor, nor shall any
such delay or omission be construed as a waiver of any breach or default, or of
any similar breach or default hereafter occurring; nor shall any waiver of a
single breach or default be deemed a waiver of any subsequent breach or default.

               SECURITY INTEREST AND INVESTMENT OF SECURITY FUNDS.

         Any moneys received by the Owner Lessor or the Lease Indenture Trustee
pursuant to Section 10.2(d) or 11.7 shall, until paid to the Facility Lessee as
provided in accordance with such Sections, be held by the Owner Lessor or the
Lease Indenture Trustee, as the case may be, as security for the Facility
Lessee's obligations under this Facility Lease and be invested in Cash
Equivalents by the Owner Lessor or the Lease Indenture Trustee, as the case may
be, at the sole risk of the Facility Lessee, from time to time as directed in
writing by the Facility Lessee if such investments are reasonably available for
purchase. Any gain (including interest received) realized as the result of any
such Cash Equivalent (net of any fees, commissions, taxes and other expenses, if
any, incurred in connection with such Cash Equivalent) shall be applied or
remitted to the Facility Lessee in the same manner as the principal invested.

                                   SECTION 19

                       FACILITY LESSEE'S RIGHT TO SUBLEASE

                  (b) the Owner Lessor, the Owner Participant, and so long as
the Lien of the Lease Indenture shall not have been terminated or discharged,

this Facility Lease) and is expressly subject and subordinate to this Facility
Lease;

                  (d) all terms and conditions of this Facility Lease and the

                  (f) the sublease prohibits further assignment or subletting;

                  (g) the sublease requires the sublessee to operate and

                  (h) the Owner Participant shall have received either (A) a
favorable legal opinion of its tax counsel satisfactory to the Owner Participant
to the effect that such sublease creates no unindemnified tax risk (determined
based on the indemnification provisions contained in the Operative Documents) to
the Owner Participant, (B) an indemnity against such risks in form and substance
reasonably satisfactory to the Owner Participant from or guaranteed by an entity

title and interest in, to and under this Facility Lease, and grant a security
interest in favor of the Lease Indenture Trustee in all of the Owner Lessor's
right, title and interest in and to the Facility Interest (other than Excepted
Payments and Excepted Rights). The Facility Lessee hereby consents to such
assignment and to the creation of such Lien and security interest and
acknowledges receipt of copies of the Lease Indenture, it being understood that
such consent shall not affect any requirement or the absence of any requirement
for any consent of the Facility Lessee under any other circumstances. Unless and
until the Facility Lessee shall have received written notice from the Lease
Indenture Trustee that the Lien of the Lease Indenture has been fully
terminated, the Lease Indenture Trustee shall have the right to exercise the
rights of the Owner Lessor under this Facility Lease to the extent set forth in

THE EXTENT, IF ANY, THAT THIS FACILITY LEASE CONSTITUTES CHATTEL PAPER (AS SUCH
TERM IS DEFINED IN THE UNIFORM COMMERCIAL CODE AS IN EFFECT IN ANY APPLICABLE
JURISDICTION), NO SECURITY INTEREST IN THIS FACILITY LEASE MAY BE CREATED
THROUGH THE TRANSFER OR POSSESSION OF ANY COUNTERPART HEREOF OTHER THAN THE
ORIGINAL COUNTERPART, WHICH SHALL BE IDENTIFIED AS THE COUNTERPART CONTAINING
THE RECEIPT THEREFOR EXECUTED BY THE LEASE INDENTURE TRUSTEE ON THE SIGNATURE

                          WAIVER OF RIGHT TO PARTITION

         So long as the Facility or any part thereof as originally constructed,
reconstructed or added to is used or useful for the generation of electrical
power and energy, or until expiration, termination or surrender of this Facility
Lease in accordance with the terms of this Facility Lease or the other Operative
Documents, whichever first occurs, and in each case not to extend beyond the
period permitted by Applicable Law, each of the Owner Lessor and the Facility
Lessee waives its right to partition, whether by partition in kind or sale and
division of the proceeds thereof, the Facility, any interest therein or portion
thereof, including the Facility Interest or any portion thereof and agrees that
it will not resort to any action at law or in equity to so partition and further
waives the benefit of all laws that may now or hereafter authorize such
partition. All instruments of conveyance which effect, evidence or vest the
ownership interest of the Owner Lessor in the Facility Interest, including the
Deed and Bill of Sale shall contain this waiver of right to partition.
