                                 CAPACITY SUPPLY

     3.1 ICAP Designation. The Supplier shall take all actions necessary on its
         ----------------
part to satisfy any requirements necessary for the certification of the Internal
ACAP Resources, and, if it so elects pursuant to the next sentence, the
pre-certification of the External ACAP Resources, in each case as qualified
capacity resources in accordance with the PJM West Protocols. The Supplier may
elect to pre-certify an amount of megawatts, up to and including 1300 megawatts
(such amount, the "Elected Amount"), of capacity from the External ACAP
Resources by delivering a written notice of the same to DLC no later than the
date that is forty-five (45) days following the date first above written, which
notice shall include the Elected Amount. The Supplier shall take all actions
necessary to designate under the PJM West Protocols, on behalf of DLC and as
DLC's agent for such purpose, beginning on the Effective Date and continuing
through the term of this Agreement (i) such generating units as Supplier may
designate that qualify as ICAP units within PJM West and have an aggregate net
demonstrated capacity of at least the Required Level of megawatts or (ii) to the
extent the aggregate net demonstrated capacity of such units does not equal at
least the Required Level of megawatts, such of Supplier's generating units at
the Internal ACAP Resources as is necessary to bring the aggregate net
demonstrated capacity of all units designated hereunder to at least the Required
Level of megawatts (all such units designated hereunder, the "Designated ICAP
Units") in any case such that DLC is deemed to have satisfied the conditions of
any Alternative Deficiency Charges resulting from such designation hereunder.
The Supplier shall be responsible for all costs, under the PJM West Protocols or
otherwise, associated with satisfying the obligations contained in this Section
3.1.

     3.2 ACAP Designation and Supply. Beginning on the calendar day immediately
         ---------------------------
preceding the Effective Date and continuing through the term of this Agreement,
on a daily basis: (i) DLC shall deliver to the Supplier, no later than three
hours prior to the close of the ACAP market then set by the PJM West Protocols,
the DLC Zone Hourly Forecasts, including the DLC Zone Daily Peak Forecast, for
the following calendar day, (ii) the Supplier shall deliver to DLC (and, on
DLC's behalf, to

                                       8
<PAGE>

FE), no later than two hours prior to the close of the ACAP market then set by
the PJM West Protocols, notice of the FE Swap Percentage that the Supplier has
set for the following calendar day, and (iii) the Supplier shall, on DLC's
behalf and as DLC's agent for such purpose, designate under the PJM West
Protocols, no later than the hour then set by the PJM West Protocols for the
close of ACAP market, from Supplier ACAP Resources an amount of ACAP equal to
the Supplier ACAP Obligation for the following calendar day and shall be
responsible for all costs, under the PJM West Protocols or otherwise, associated
therewith. The Parties agree that in designating ACAP from Supplier ACAP
Resources on a particular day, the Supplier shall, on DLC's behalf and as DLC's
agent for such purpose, (i) designate under the PJM West Protocols ACAP from the
Designated ICAP Units in an amount equal to the ACAP Insurance Amount (to the
extent such amount of ACAP is physically available from the Designated ICAP
Units on such day), and (ii) bid into the ACAP market under the PJM West
Protocols all available ACAP from Designated ICAP Units in excess of the ACAP
Insurance Amount. The Parties further agree to cooperate in good faith to
establish a process pursuant to which the Supplier, in satisfying its
obligations to deliver the Supplier ACAP Obligation, may, on DLC's behalf and as
DLC's agent for such purpose, enter into ACAP market transactions under the PJM
West Protocols to purchase an amount of ACAP to meet the unsupplied balance, if
any, of the Supplier ACAP Obligation (or if the PJM West Protocols do not permit
the Supplier to act as DLC's agent for such purposes, a process pursuant to
which the Supplier and DLC will cooperate to enter into such ACAP market
transactions), provided that the Supplier shall be responsible for all costs
associated with all such ACAP market transactions (such costs, the "ACAP Market
Transaction Costs"), which ACAP Market Transaction Costs shall be immediately
due and payable to DLC and, as such, shall be included as a component of
"Supplier Charges" imposed on the Supplier under the POLR II Agreement, as
contemplated by the POLR II Amendments. The Parties agree that "ACAP Market
Transaction Costs" shall also include all costs associated with ACAP market
transactions executed on DLC's behalf by PJM West under the PJM West Protocols,
including any buy bids thereunder, to secure the ACAP necessary to supply any
portion of the Supplier ACAP Obligation. In addition, the Parties shall use
their best efforts to certify the Interruptible Service (as defined under the
POLR Agreement and the POLR II Agreement) as "Qualified Interruptible Load"
under the PJM West Protocols for the purpose of inclusion as an "Available
Capacity Resource" under the PJM West Protocols.

     3.3 ACAP Deficiencies. Beginning on the Effective Date and continuing
         -----------------
through the term of this Agreement, if on any calendar day there is a Supplier
ACAP Deficiency, the Supplier shall be responsible for any charges assessed to
or imposed on DLC under the PJM West Protocols (or charges incurred by DLC on
behalf of EGSs under the PJM West Protocols) in respect of any such Supplier
ACAP Deficiency (such charges, the "Supplier ACAP Deficiency Charges"), which
Supplier ACAP Deficiency Charges shall be immediately due and payable to DLC and
included as a component of "Supplier Charges" imposed on the Supplier under the
POLR II Agreement, as contemplated by the POLR II Amendments; provided, however,
that any Supplier ACAP Deficiency Charges shall take into account, so that the
Supplier is entitled to the benefit of, up to the amount of the Supplier ACAP
Obligation, any Alternative Deficiency Charges resulting from and to the extent
of any ACAP Insurance

                                       9
<PAGE>

Amount, so long as the Supplier has complied with its obligations contained in
Sections 3.1 and 3.2 hereof. The Parties agree that "Supplier ACAP Deficiency
Charges" shall also include all charges assessed to or imposed on DLC under the
PJM West Protocols (or charges incurred by DLC on behalf of EGSs under the PJM
West Protocols) as a result of the Supplier's failure to designate as ACAP or
bid into the ACAP market, in either case as may be required under the PJM West
Protocols, the full amount of available ACAP of the Designated ICAP Units.

     3.4 Payment for ACAP. Beginning on the twentieth day after the end of the
         ----------------
calendar month during which the Effective Date occurs (or if such day is not a
Business Day, then on the next succeeding Business Day), and continuing monthly
on the tenth day after the end of each successive calendar month (or if such day
is not a Business Day, then on the next succeeding Business Day) through the
term of this Agreement, DLC shall pay to the Supplier the ACAP Supply Payment
for the preceding calendar month. The Parties recognize and agree that they
shall, as necessary, pro rate on a daily basis the ACAP Supply Payment for the
month during which the Effective Date occurs to account, and pay the Supplier
only, for the number of days during such month that the Supplier was obligated
to deliver the Supplier ACAP Obligation hereunder.

     3.5 Taxes. The payment of any local, state and federal taxes, fees, and
         -----
levies ("Governmental Charges") imposed on or with respect to the Supplier's
delivery of the Supplier ACAP Obligation shall be the responsibility of the
Supplier.

     3.6 Payments and Payment Disputes. Except as may otherwise be provided in
         -----------------------------
this Agreement, beginning on the Effective Date and continuing on each Business
Day thereafter through the term of this Agreement, all payments then due under
this Agreement shall be made to the Party owed such payment by electronic
transmission to the bank account designated by such Party in Section 12.3
hereof. All such payments shall be denominated and paid in U.S. dollars. The
Parties shall use their good faith best efforts to resolve all disputes relating
to payments hereunder pursuant to the dispute resolution provisions of Article
VII of this Agreement.

     3.7 Survival of Payment Obligations. Notwithstanding any other provision of
         -------------------------------
this Agreement to the contrary, the payment provisions of this Article III, and
the rights and obligations of the Parties thereunder, shall survive the
expiration of the term or the termination of this Agreement for the purpose of
satisfying the rights and obligations of the Parties that arose or accrued prior
to such termination or expiration relating to the payment of the ACAP Supply
Payments, Supplier ACAP Deficiency Charges and ACAP Market Transaction Costs.

     3.8 Fixed Transmission Rights and Network Resource Designations. Beginning
         -----------------------------------------------------------
on the Effective Date and continuing through the term of this Agreement, upon
receipt of written notice from the Supplier requesting such transfer, DLC shall
transfer to the Supplier its rights to those "Fixed Transmission Rights", if
any, under the PJM West Protocols that are associated, from time to time, with
such amount of megawatts as are designated from the Supplier's resources as
"Network Resources" under the PJM West Protocols. In addition, beginning on the
Effective Date and

                                       10
<PAGE>

continuing through the term of this Agreement, DLC, at the Supplier's request,
shall, as permitted under the PJM West Protocols, designate such amount of
megawatts as the Supplier may elect from its resources as "Network Resources"
under the PJM West Protocols.

                                   ARTICLE IV

Toward that end, in connection with the execution and delivery of this
Agreement, the Parties, on even date herewith, shall execute and deliver the
Ancillary Services Agreement.

     4.4 Amended Connection Agreements. The Parties recognize and agree that

the form attached hereto as Exhibit 2, forms an integral part of this Agreement
and forms a part of the consideration for the obligations of the Parties

                                    ARTICLE V
                                  FORCE MAJEURE

     5.1 Force Majeure. Notwithstanding anything in this Agreement to the
         -------------
contrary, neither Party shall be liable in damages, or otherwise responsible to
the other Party, for its failure to perform or observe any of its obligations
under this Agreement if and only to the extent that it is unable to so perform
or is prevented from performing by an event of Force Majeure; provided, however,
that to the extent that the Supplier fails to deliver the Supplier ACAP
Obligation in accordance with Section 3.2 hereof, whether as a result of an
event of Force Majeure or for any other reason, the provisions of Section 3.3
hereof shall apply to such failure. The Parties recognize and agree that an
event of Force Majeure will not relieve any Party of its obligation to make
payments when due hereunder.

     5.2 Definition of Force Majeure. The term "Force Majeure" as used herein
         ---------------------------
means those causes beyond the reasonable control of the Party affected that, by
the exercise of reasonable diligence, including Good Utility Practice, such

God, labor dispute (including a strike), act of the public enemy, war, civil
disturbance, insurrection, riot, fire (unless resulting from the fault or
negligence of the Party asserting Force Majeure), storm or flood, lightning,
explosion (unless resulting from the fault or negligence of the Party asserting
Force Majeure), order, government decree or rule, regulation or restriction
imposed by governmental, military or lawfully-established civilian authorities,
or any other cause of a similar nature beyond such Party's reasonable control.
Events that cause a change in the market value of capacity or otherwise affect
the Supplier's or DLC's cost of performance under this Agreement or that are
otherwise covered by Section 6.2(b) of this Agreement shall not be considered
Force Majeure events.

     5.3 Force Majeure Procedures. Upon the occurrence of an event of Force
         ------------------------
Majeure, the Party affected by such event shall (a) provide prompt written
notice of such Force Majeure event to the other Party, including an estimation
of its expected duration and the probable impact on the performance of its
obligations hereunder; (b) exercise all reasonable efforts in accordance with
Good Utility Practice to continue to perform its obligations under this
Agreement; (c) expeditiously take action to correct or cure the event or
condition excusing performance, provided, however, that settlement of labor
disputes will be completely within the sole discretion of the Party affected by
such labor dispute; (d) exercise all reasonable efforts to mitigate or limit
damages to the other Party; and (e) provide prompt notice to the other Party of
the cessation of the event or condition giving rise to its excuse from
performance. Any obligation under this Agreement shall be suspended only to the

inability of performance caused by such Force Majeure event but for no longer
period.

                                   ARTICLE VI
                             DEFAULT AND TERMINATION

     6.1 Event of Default. Unless excused by Force Majeure, each of the
         ----------------
following events shall be considered an Event of Default:

          (a) The material breach by either Party of any agreement, covenant or
obligation under this Agreement; provided that such breach is not caused by the
material breach of the other Party, and provided further that, if such breach is
curable, a default shall not occur until the Party in breach has failed to cure
such breach within thirty (30) days after receipt of written notice thereof by
the non-defaulting Party;

          (b) The discovery that any representation or warranty made by a Party
hereunder was false or misleading in any material respect when made that is not
cured within thirty (30) days and which has a material adverse effect on the
ability of the Party making such representation or warranty to perform its
obligations hereunder;

          (c) The filing of an involuntary petition in bankruptcy against either
Party or the appointment of a receiver or liquidator or trustee for either Party
or of any substantial part of the property of a Party, provided that if such
Party is working diligently to have such petition, receiver, liquidator or
trustee stayed, dismissed or discharged, a default shall not occur unless such
petition, receiver, liquidator or trustee is not stayed, dismissed or discharged
within thirty (30) days ;

          (d) The entry of a decree adjudicating a Party or any substantial part
of the property of a Party bankrupt or insolvent, provided that if such Party is
working diligently to have such decree discharged or stayed, a default shall not
occur unless such decree is continued undischarged and unstayed for a period of
thirty (30) days;

                                       13
<PAGE>

          (e) The filing of a voluntary petition in bankruptcy under any
provision of any federal or state bankruptcy law by a Party or against it;

          (f) The failure of either Party to pay the other Party undisputed
amounts owed within ten (10) days after receiving written notice from such Party
that any such amount is overdue;

          (g) A default by the Supplier on its indebtedness to third parties,
resulting in obligations of the Supplier in an amount of $50,000,000 or more
being accelerated;

     6.2 Termination.
         -----------

          (a) Upon the occurrence of an Event of Default, the non-defaulting
Party may terminate this Agreement by providing one hundred eighty (180) days'
written notice to the defaulting Party of a specified date of termination;
provided, however, that upon the occurrence of an Event of Default specified in
Section 6.1 (c), (d) and (e) hereof, the non-defaulting Party may terminate this
Agreement by delivering to the defaulting Party a written notice of termination,
which termination shall be effective upon the defaulting Party's receipt of such
notice. The non-defaulting Party may exercise all such rights and remedies as
may be available to it to recover damages caused by such Event of Default.

          (b) Following the Effective Date, if:

          (i) the PUC issues an order modifying the Retail Tariff Changes
     (together with such changes thereto as may have been acceptable to DLC on
     or prior to the Effective Date) in a manner that materially impairs DLC's
     ability to recover from its customers the amounts paid to the Supplier
     under this Agreement,

          (ii) either (x) the PUC issues an order modifying the Supplier Tariff
     Changes (together with such changes thereto as may have been acceptable to
     the Parties on or prior to the Effective Date), (y) the FERC issues an
     order or (z) the PJM West Protocols or FE Protocols are modified, in any
     such case, in a manner that affects the rights or obligations of a Party
     respecting matters under this Agreement so as to cause such Party a
     Material Adverse Effect (but specifically excluding from this clause (ii)
     any order or modification as a result of which DLC is no longer able to
     satisfy its capacity obligations under the PJM West Protocols by supplying
     ACAP), or

          (iii) DLC is no longer able to satisfy its capacity obligations under
     the PJM West Protocols by supplying ACAP,

then, the affected Party may deliver written notice of the occurrence of any
such event(s) to the other Party (such notice, a "Renegotiation Notice").
Promptly after the delivery and receipt of a Renegotiation Notice, the Parties
shall, in good faith, attempt to negotiate

                                       14
<PAGE>

a mutually satisfactory amendment to this Agreement to restore the respective
rights and obligations of the Parties under this Agreement as they existed
immediately prior to such event(s) or to achieve another mutually satisfactory
result. If within thirty (30) days following the delivery of any such
Renegotiation Notice that notices an event described in clause (i), (ii) or
(iii) hereof the Parties fail to agree upon any such amendment, the affected
Party may then terminate the Agreement by providing the other Party with one
hundred eighty (180) days' prior written notice of such termination. Any
amendment to this Agreement negotiated as a result of a Renegotiation Notice
shall be deemed to be retroactively effective to the date on which the event(s)
described in such Renegotiation Notice occurred; provided, however, that if
following any such event, the order giving rise to such event is no longer in
effect (or is modified in a manner described in clause (i), (ii) or (iii)
hereof) by virtue of a decision by a Governmental Authority or governing body
that has become final and non-appealable, then any such amendment shall be of no
further force and effect and this Agreement shall be read so as not to include
such amendment (and in the event such order is modified in a manner described in
clause (i), (ii) or (iii) hereof, the Parties may deliver a Renegotiation Notice
with respect thereto as otherwise contemplated hereunder). Upon any termination
pursuant to this Section 6.2(b), neither Party shall have any further liability
to the other Party under this Agreement, except for any obligations that arose
or accrued prior to the effective date of such termination.

          (c) If, following the Effective Date, the FE Capacity Agreement is
terminated, DLC shall immediately so notify the Supplier and then as of the date
on which the FE Capacity Agreement's termination is effective, this Agreement
shall be amended so that: (i) the Supplier shall continue to be obligated to
supply ICAP as contemplated by Section 3.1 hereof, (ii) in lieu of supplying the
Supplier ACAP Obligation, the Supplier shall, on DLC's behalf and as DLC's agent
for such purpose, supply on each calendar day the lesser of (x) an amount of
ACAP equal to the Required Level of megawatts of net capacity or (y) an amount
of ACAP equal to the amount of ACAP then required by PJM West for the DLC Zone
for such calendar day under the PJM West Protocols, (iii) the Supplier shall be
responsible for any charges assessed to or imposed on DLC, or incurred by DLC on
behalf of EGSs, under the PJM West Protocols for the Supplier's failure to
supply ICAP and ACAP as contemplated by this Agreement as modified by this
Section 6.2(c), and (iv) the Supplier shall continue to receive the ACAP Supply
Payment. In addition, if, following the Effective Date, the FE Capacity
Agreement is terminated, following such termination and continuing until the
termination or the expiration of the POLR II Agreement, DLC shall, beginning
with the next monthly payment of the ACAP Supply Payment, increase the amount of
the monthly ACAP Supply Payment by an additional $750,000.

          (d) If the POLR II Agreement is terminated, then the Parties shall
negotiate in good faith such amendments to this Agreement as shall be necessary
to (i) provide that all payments due DLC under this Agreement are to be invoiced
by DLC and paid by the Supplier to DLC on a weekly basis, and all payments due
either Party under the Ancillary Services Agreement are to be invoiced by DLC
and paid and/or offset by the appropriate Party, as necessary, on a monthly
basis, in each case with subsequent monthly settlement statements of account
(and any related payments) and monthly true-

                                       15
<PAGE>

up statements of account (and any related payments), to be delivered (and paid)
in a manner that is substantially similar to those invoices and statements of
account (and any related payments) contemplated by the POLR II Agreement as
amended by the POLR II Agreement Amendments attached hereto, (ii) provide that
the Supplier shall post, supplement and replace letter(s) of credit in favor of
DLC, and that DLC may draw on any such letter(s) of credit, in such amounts and
in circumstances that are substantially similar to those contemplated by the
POLR II Agreement as amended by the POLR II Agreement Amendments attached
hereto, and (iii) provide DLC with remedies in the event that the Supplier fails
to post, supplement or replace any such letter(s) of credit that are
substantially similar to those contemplated by the POLR II Agreement as amended
by the POLR II Agreement Amendments attached hereto.

     6.3 Additional Remedies. The Supplier acknowledges and specifically agrees
         -------------------
that its obligations under this Agreement are essential to ensure the
reliability of the DLC Zone; that breach of the Supplier's obligations may
result in irreparable harm and damage to DLC which cannot adequately be
compensated by a monetary award; and that, as a consequence thereof, DLC shall,
in addition to any other remedy to which DLC may be entitled by reason of the
Supplier's breach of this Agreement, be entitled to seek and obtain temporary,
preliminary and permanent injunctive relief from any court or Governmental
Authority of competent jurisdiction restraining the Supplier from committing or
continuing any breach of this Agreement.

     6.4 Reimbursement for Replacement Costs.
         -----------------------------------

          (a) Upon the termination of this Agreement pursuant to Section 6.2(a)
hereof as a result of any Event of Default, other than those Events of Default
specified in Sections 6.1(c), (d) and (e) hereof, the defaulting Party shall be
liable to the non-defaulting Party for all losses and costs reasonably incurred
by the non-defaulting Party as a direct result of the defaulting Party's Event
of Default, including all reasonable costs associated with replacing the
obligations of the defaulting Party hereunder.

          (b) Upon the termination of this Agreement pursuant to Section 6.2(a)
hereof as a result of an Event of Default specified in Sections 6.1(c), (d) and
(e) hereof, the defaulting Party shall be liable to the non-defaulting Party for
all of the non-defaulting Party's Losses (as defined in the next sentence) as a
result thereof. For purposes of this Section 6.4(b), "Losses" means an amount
that the non-defaulting Party, or its agent, determines in good faith and in a
commercially reasonable manner to be the total losses and costs, net of gains,
that the non-defaulting Party has and/or would incur in replacing the
obligations of the defaulting Party for the remaining term of this Agreement.
The non-defaulting Party, or its agent, may determine such Losses by using
pricing or other valuation models and by reference to information available to
it internally or supplied by one or more third parties (including, without
limitation, dealers, information vendors and other sources of market
information), which information may include, without limitation, quotations
(either firm or indicative) of relevant rates, prices, yields, yield curves,
volatilities, spreads or other relevant market data in the relevant

                                       16
<PAGE>

markets. The defaulting Party shall pay an amount equal to the Losses to the
non-defaulting Party within thirty (30) days after the defaulting Party receives
written notice from the non-defaulting Party of such amount.

          (c) In addition to the foregoing amounts, the defaulting Party shall
be liable for reasonable administrative and legal expenses incurred by the
non-defaulting Party as a result of the defaulting Party's Event of Default. The
Parties expressly agree that the obligations of each Party under this Section
6.4 shall survive and continue in full force following any termination of this
Agreement pursuant to Section 6.2(a) hereof.

                                  ARTICLE VII
                               DISPUTE RESOLUTION

     7.1 Disputes. A Party with a claim or dispute under this Agreement shall
         --------
submit to the other Party a notification of such claim or dispute within sixty
(60) days of the date on which the Party knew of the occurrence of the
circumstances that gave rise to the claim or the question or issue in dispute,
and shall provide the Administration Committee (as defined in the POLR II
Agreement) with a copy of such notification. Any such notification shall be in
writing and shall include a concise statement of the claim or the issue or
question in dispute, a statement of the relevant facts and documentation to
support the claim. The Administration Committee (as defined in the POLR II
Agreement) shall use its good faith best efforts to resolve the claim or dispute
within thirty (30) days after its receipt of a notification specifying the
claim, issue or question in dispute. If the Administration Committee (as defined
in the POLR II Agreement) is unable to do so, the Parties shall refer the claim
or dispute to their respective senior management. Subject to Section 7.4 hereof,
if, after using their good faith best efforts to resolve the dispute, the
Parties' senior management cannot resolve the dispute within thirty (30) days,
the Parties may, if they both so agree in writing, utilize the alternative
dispute resolution procedures set forth below in Sections 7.2 and 7.3 hereof.

     7.2 Arbitration. Any arbitration initiated under this Agreement shall be
         -----------
conducted before a single neutral arbitrator appointed by the Parties within
thirty (30) days of receipt by respondent of the demand for arbitration. If the
Parties are unable to agree on an arbitrator, such arbitrator shall be appointed
by the American Arbitration Association. Unless the Parties agree otherwise, the
arbitrator shall be an attorney or retired judge with at least fifteen (15)
years of experience and shall not have any current or past substantial business
or financial relationships with any Party to the arbitration. In addition, if
possible, the arbitrator shall have significant system operations experience in
the electric industry. Unless otherwise agreed, the arbitration shall be
conducted in accordance with the American Arbitration Association's Commercial
Arbitration Rules, then in effect, in Pittsburgh, Pennsylvania. Any arbitration
proceedings, decision or award rendered hereunder and the validity, effect and
interpretation of this arbitration agreement shall be governed by the Federal
Arbitration Act of the United States, 9 U.S.C. Sections 1 et seq.

     7.3 Arbitration Terms. The arbitration shall, if possible, be concluded not
         -----------------
later that six (6) months after the date that it is initiated. The arbitrator
shall be authorized only to interpret and apply the provisions of this Agreement
or any related agreements entered into under this Agreement and shall have no
power to modify or change any of the above in any manner. The arbitrator shall
have no authority to award punitive or multiple damages or any damages
inconsistent with this Agreement. The arbitrator shall, within thirty (30) days
of the conclusion of any hearing, unless such time is extended by agreement of
the Parties, notify the Parties in writing of his or her decision, stating his
or her reasons for such decision and separately listing his or her findings of
fact and conclusions of law. The decision of the arbitrator rendered in such a
proceeding shall be final and binding on the Parties. Judgment on any award made
by the arbitrator may be entered in any court having jurisdiction.

     7.4 FERC Jurisdiction. Notwithstanding any other provision of this
         -----------------
Agreement to the contrary, nothing in this Agreement shall preclude, or be
construed to preclude, any Party from filing a petition or complaint with FERC
with respect to any arbitrable claim over which FERC has jurisdiction. In such a
case, the other Party may request FERC to reject or to waive jurisdiction. If
FERC rejects or waives jurisdiction with respect to all or a portion of such
claim, the portion of such claim not so accepted by FERC may be resolved through
arbitration, as provided in this Agreement. To the extent that FERC asserts or
accepts jurisdiction over such claim, the decision, findings of fact or order of
FERC shall be final and binding, subject to judicial review under the Federal
Power Act, and any arbitration proceedings that may have commenced with respect
to such claim prior to the assertion or acceptance of jurisdiction by FERC shall
be terminated.

facilities and other assets associated with the Asset Sale (as defined in the
POLR Agreement and the POLR II Agreement), including upon or pursuant to the
exercise of remedies under such financing or refinancing, or by way of
assignments, transfers, conveyances of dispositions in lieu thereof; provided,
however, that no such assignment or disposition shall relieve or in any way
discharge the Supplier or any such permitted assignee from the performance of
the duties and obligations of the Supplier under this Agreement. DLC agrees to
execute and deliver such documents as may be reasonably necessary to accomplish
any such assignment, transfer, conveyance, pledge or disposition of rights
hereunder for purposes of such

                                       18

materially altered, amended, diminished or otherwise impaired thereby.

     8.2 Release of Rights and Obligations. No assignment (including a merger,
         ---------------------------------
consolidation or sale of all or substantially all of the assets of the
Supplier), transfer, conveyance, pledge or disposition of rights, interests,
duties or obligations under this Agreement by a Party shall relieve that Party
from liability and financial responsibility for the performance thereof after
any such transfer, assignment, conveyance, pledge or disposition unless and
until (i) the transferee or assignee shall agree in writing to assume the
obligations and duties of that Party under this Agreement and (ii) the
non-assigning Party has consented in writing to such assumption and to a release
of the assigning Party from such liability, such consent not to be unreasonably
conditioned, delayed or withheld.

          ---------------------
the Supplier, its parent, its Affiliates, and its and their successors,
officers, directors, employees, shareholders, agents, contractors,

demands, suits, obligations, payments, liabilities, costs, losses, judgments,
damages and expenses (including the costs and expenses of any and all actions,
suits, proceedings, assessments, judgments, settlements, and compromises
relating thereto, reasonable attorneys' and expert fees and reasonable
disbursements in connection therewith) for damage to property, injury to or
death of any Person, including the Supplier's employees, DLC's employees and
their Affiliates' employees, or any third parties, to the extent caused wholly
or in part by any act or omission, negligent or otherwise, by DLC or its
officers, directors, employees, agents, contractors, subcontractors and invitees
arising out of or connected with DLC's performance or breach of this Agreement,
or the exercise by DLC of its rights hereunder. In furtherance of the foregoing
indemnification and not by way of limitation thereof, DLC hereby waives any
defense it otherwise might have under applicable workers' compensation laws.

     10.2 Supplier's Indemnification. The Supplier shall indemnify, hold
          --------------------------
harmless and defend DLC, its parent, Affiliates, and its and their successors,
officers, directors, employees, shareholders, agents, contractors,
subcontractors, invitees and successors, from and against any and all claims,
demands, suits, obligations, payments, liabilities, costs, losses, judgments,
damages and expenses (including the costs and expenses of any and all actions,
suits, proceedings, assessments, judgments, settlements, and compromises

commencement of the event or circumstance giving rise to the claim. Such notice
shall describe the claim in reasonable detail, and shall indicate the amount
(estimated if necessary) of the claim that has been, or may be sustained by,
said Party. To the extent that the other Party will have been actually and
materially prejudiced as a result of the failure to provide such notice, such
notice will be a condition precedent to any liability of the other Party under

POLR Supplier shall pay to DLC, in accordance with the billing procedures set
forth in Article VII of this Agreement, the following amounts, as applicable:

               (a) DLC POLR Energy Imbalance. If the POLR Supplier fails to
                   -------------------------
deliver to the DLC Zone the DLC POLR Supply Amount for such hour, the POLR
Supplier shall in the event of an under-delivery, pay to DLC an amount of
dollars equal to the charge under the PJM West Protocols applicable to an
under-delivery of an amount of Energy equal to the DLC POLR Energy Imbalance,
and in the event of an over-delivery, receive a credit from DLC in an amount of
dollars equal to the credit under the PJM West Protocols applicable to an
over-delivery of an amount of Energy equal to the DLC POLR Energy Imbalance (net
of any costs DLC incurs in disposing of such Energy). For the avoidance of
doubt, the POLR Supplier's delivery of Energy to the DLC Zone in any given hour
shall first be allocated to the DLC POLR Supply Amount under this Agreement and
then to the DLC POLR Supply Amount under the POLR II Agreement. In addition, if
the POLR Supplier's failure to deliver the POLR Supply Amount in accordance with
Section 4.1 hereof causes DLC to Shed Load during any hour, the POLR Supplier
shall pay to DLC, in addition to any amounts otherwise due hereunder, $1,000 per
megawatt-hour of Shed Load attributable to such failure plus any out-of-pocket
costs incurred by DLC as the result of claims, penalties, repairs, expenses or
other damages resulting from such Shed Load; provided, however, that if during
any such hour (x) the POLR Supplier delivers the full output of all of its
operable generation (e.g., all generation in the DLC Control Area and the FE
Control Area that is not on forced or planned outage and/or forced or planned
curtailments) to the DLC Control Area and, to the extent applicable under this
Agreement, the FE Control Area (and delivers to DLC a certificate executed by a
duly authorized officer of the POLR Supplier to such effect) and nevertheless
fails to deliver the POLR Supply Amount and (y) DLC is unable to procure
alternative sources of Energy in the market sufficient to compensate for the

                                       6
<PAGE>

POLR Supplier's under-delivery, then the POLR Supplier shall pay to DLC, in
addition to any amounts otherwise due hereunder, but in lieu of the $1,000 per
megawatt-hour of Shed Load described above, $100 per megawatt-hour of Shed Load
attributable to such failure plus any of the aforementioned out-of-pocket costs
incurred by DLC. For purposes of this Section 4.3(a), DLC shall determine the
amount of such Shed Load using Good Utility Practice.

               (b) FE POLR Energy Imbalance. If the POLR Supplier fails to
                   ------------------------
deliver to the FE Control Area the FE POLR Supply Amount for such hour, the POLR
Supplier shall in the event of an under-delivery, pay to DLC an amount of
dollars equal to the FE Charge applicable to an under-delivery of an amount of
Energy equal to the FE POLR Energy Imbalance, and in the event of an
over-delivery, receive a credit from DLC in an amount of dollars equal to the FE
Credit applicable to an over-delivery of an amount of Energy equal to the FE
POLR Energy Imbalance (net of any costs DLC incurs in disposing of such Energy).
For the avoidance of doubt, the POLR Supplier's delivery of Energy to the FE
Control Area in any given hour shall first be allocated to the FE POLR Supply
Amount under this Agreement and then to the FE POLR Supply Amount under the POLR
II Agreement.

               (c) Reserved.
                   --------

     Section 4.3 is hereby amended by adding the following new Section 4.3(f)

Violation Charges. On a daily basis, no later than the prevailing time deadline
in the PJM West Protocols for internal transactions, the POLR Supplier shall
have completed any E-schedules contemplated by Section 5.2 hereof in respect of
the DLC POLR Supply Amounts for the preceding calendar day and shall deliver to
DLC an FE Tally Sheet in respect of the FE POLR Supply Amounts for the preceding
calendar day. The Parties recognize and agree that POLR Energy Imbalance is
comprised of FE POLR Energy Imbalance and DLC POLR Energy Imbalance and that
separate Supply Violation Charges shall be calculated for any FE POLR Energy
Imbalance and any DLC POLR Energy Imbalance.

          Supply Amount and (y) DLC is unable to procure alternative sources of
          Energy in the market sufficient to compensate for the POLR Supplier's
          under-delivery, then the POLR Supplier shall pay to DLC, in addition
          to any amounts otherwise due hereunder, but in lieu of the $1,000 per
          megawatt-hour of Shed Load described above, $100 per megawatt-hour of
          Shed Load attributable to such failure plus any of the aforementioned
          out-of-pocket costs incurred by DLC. For purposes of this Section

                   -------------------

               (a) In addition to any other right to offset against payments to
          the POLR Supplier under this Agreement, DLC shall have the right to
          offset any amounts the POLR Supplier owes DLC pursuant to Sections
          7.2, 7.3 and 7.4 hereof (except for such amounts reasonably disputed
          by the POLR Supplier) against the amounts owed by DLC pursuant to
          Section 7.1 hereof. In doing so, on any particular day, if an amount
          is owing to DLC pursuant to Section 7.2, Section 7.3 or Section 7.4
          hereof,

                                       18
<PAGE>

          DLC may retain such portion of the Net Billed Generation Revenue
          otherwise owing to the POLR Supplier under Section 7.1 hereof for such
          day as an offset in satisfaction thereof; if any such amount owing to
          DLC exceeds the Net Billed Generation Revenue otherwise owing to the
          POLR Supplier under Section 7.1 hereof for such day, DLC may retain
          such Net Billed Generation Revenue as an offset and withhold further
          payments of Net Billed Generation Revenue otherwise owing to the POLR
          Supplier under Section 7.1 hereof as an offset until the amount owing
          to DLC pursuant to Sections 7.2, 7.3 and 7.4 has been fully recovered
          by DLC.

               (b) In addition to the right to offset set forth in Section
          7.5(a), if, on any day after reviewing the E-schedules described in
          Section 5.3 hereof attributable to the immediately preceding calendar
          day, DLC determines that the Preliminary Supplier Charges for such day
          exceed $5 million, such Preliminary Supplier Charges shall become
          immediately due from the POLR Supplier and payable to DLC as an
          offset. In such an instance, DLC may retain such portion of the Net
          Billed Generation Revenue otherwise owing to the POLR Supplier under
          Section 7.1 hereof for such day equal to such Preliminary Supplier
          Charges as an offset in satisfaction thereof; if any such Preliminary
          Supplier Charges owing to DLC exceeds the Net Billed Generation
          Revenue otherwise owing to the POLR Supplier under Section 7.1 hereof
          for such day, DLC may retain such Net Billed Generation Revenue as an
          offset and withhold further payments of Net Billed Generation Revenue
          otherwise owing to the POLR Supplier under Section 7.1 hereof as an
          offset until the amount of such Preliminary Supplier Charges has been
          fully recovered by DLC.

               7.6 Right to Immediate Payment and to Draw on Letter of Credit.
                   ----------------------------------------------------------
          In addition to the rights to offset under Section 7.5 hereof, DLC
          shall further have the right to immediate payment from the POLR
          Supplier, and to draw upon the letter(s) of credit posted by the POLR
          Supplier under the terms of this Agreement, in the amounts and under
          the circumstances provided below:

               (a) If at any time Preliminary Supplier Charges or Supplier
          Charges in an amount in excess of $30 million are then due from the
          POLR Supplier and payable to DLC under the terms of this Agreement and
          the POLR II Agreement (as defined under the Capacity Agreement), DLC
          shall provide notice of the same to the POLR Supplier and, upon
          receipt thereof, the POLR Supplier shall make immediate payment to DLC
          of the dollar amount of such Preliminary Supplier Charges or Supplier
          Charges, as the case may be, in immediately available funds to the
          bank account designated by DLC in Section 15.3 hereof.

               (b) If, within ten (10) days following notice to the POLR
          Supplier given by DLC pursuant to Section 7.6(a), DLC has not received

                                       19
<PAGE>

          payment in full of the Preliminary Supplier Charges or Supplier
          Charges so noticed, then DLC has the right to draw upon the letter(s)
          of credit posted by the POLR Supplier under the terms of this
          Agreement in an amount up to, but not exceeding, any portion of such
          Preliminary Supplier Charges or Supplier Charges then unpaid by the
          POLR Supplier, and if DLC draws upon such letter(s) of credit, such
          letter(s) of credit are insufficient to pay to DLC such Preliminary
          Supplier Charges or Supplier Charges and the POLR Supplier fails to
          replace such letter(s) of credit with letter(s) of credit in such
          amounts as are sufficient to pay to DLC such Preliminary Supplier
          Charges or Supplier Charges, then DLC shall also have the right to
          terminate this Agreement upon ten (10) days written notice to the POLR
          Supplier.

          Section 7.9 shall be amended and restated in its entirety as follows:

          expiration of this Agreement.

               (b) In addition to the foregoing and notwithstanding any other
provision of this Section 15.13 to the contrary, in the event, and only in the
event, that the FE Capacity Agreement is terminated but the Capacity Agreement
is not terminated, this Agreement shall be further amended as set forth below

     modification of the Generation Rates (other than (x) as contemplated by the
     Retail Tariff Changes (as defined under the Capacity Agreement) together
     with such changes to the Retail Tariff Changes as may have been acceptable
     to DLC on or prior to the Capacity Agreement Effective Date, and (y) a
     request by DLC for a change in the PJM West Surcharge), unless the Parties
     shall mutually agree otherwise.

     Sections 4.3(a), (b) and (c) are hereby amended and restated in their
entirety as follows:

          4.3 POLR Energy Imbalance and Supply Violation Charges. For any hour
              --------------------------------------------------
during which there is DLC POLR Energy Imbalance or FE POLR Energy Imbalance, the
POLR Supplier shall pay to DLC, in accordance with the billing procedures set
forth in Article VII of this Agreement, the following amounts, as applicable:

               (a) DLC POLR Energy Imbalance. If the POLR Supplier fails to
                   -------------------------
deliver to the DLC Zone the DLC POLR Supply Amount for such hour, the POLR
Supplier shall in the event of an under-delivery, pay to DLC an amount of
dollars equal to the charge under the PJM West Protocols applicable to an
under-delivery of an amount of Energy equal to the DLC POLR Energy Imbalance,
and in the event of an over-delivery, receive a credit from DLC in an amount of
dollars equal to the credit under the PJM West Protocols applicable to an
over-delivery of an amount of Energy equal to the DLC POLR Energy Imbalance (net
of any costs DLC incurs in disposing of such Energy). For the avoidance of
doubt, the POLR Supplier's delivery of Energy to the DLC Zone in any given hour
shall first be allocated to the DLC POLR Supply Amount under the POLR I
Agreement and then to the DLC POLR Supply Amount under this Agreement. In
addition, if the POLR Supplier's failure to deliver the POLR Supply Amount in
accordance with Section 4.1 hereof causes DLC to Shed Load during any hour, the
POLR Supplier shall pay to DLC, in addition to any amounts otherwise due
hereunder, $1,000 per megawatt-hour of Shed Load attributable to such failure
plus any out-of-pocket costs incurred by DLC as the result of claims, penalties,
repairs, expenses or other damages resulting from such Shed Load; provided,
however, that if during any such hour (x) the POLR Supplier delivers the full
output of all of its operable generation (e.g., all generation in the DLC
Control Area and the FE Control Area that is not on forced or planned outage
and/or forced or planned curtailments) to the DLC Control Area and, to the
extent applicable under this Agreement, the FE Control Area (and delivers to

                                       7
<PAGE>

DLC a certificate executed by a duly authorized officer of the POLR Supplier to
such effect) and nevertheless fails to deliver the POLR Supply Amount and (y)
DLC is unable to procure alternative sources of Energy in the market sufficient
to compensate for the POLR Supplier's under-delivery, then the POLR Supplier
shall pay to DLC, in addition to any amounts otherwise due hereunder, but in
lieu of the $1,000 per megawatt-hour of Shed Load described above, $100 per
megawatt-hour of Shed Load attributable to such failure plus any of the
aforementioned out-of-pocket costs incurred by DLC. For purposes of this Section
4.3(a), DLC shall determine the amount of such Shed Load using Good Utility
Practice.

               (b) FE POLR Energy Imbalance. If the POLR Supplier fails to
                   ------------------------
deliver to the FE Control Area the FE POLR Supply Amount for such hour, the POLR
Supplier shall in the event of an under-delivery, pay to DLC an amount of
dollars equal to the FE Charge applicable to an under-delivery of an amount of
Energy equal to the FE POLR Energy Imbalance, and in the event of an
over-delivery, receive a credit from DLC in an amount of dollars equal to the FE
Credit applicable to an over-delivery of an amount of Energy equal to the FE
POLR Energy Imbalance (net of any costs DLC incurs in disposing of such Energy).
For the avoidance of doubt, the POLR Supplier's delivery of Energy to the FE
Control Area in any given hour shall first be allocated to the FE POLR Supply
Amount under the POLR I Agreement and then to the FE POLR Supply Amount under
this Agreement.

               (c) Reserved.
                   --------

     Section 4.3 is hereby amended by adding the following new Sections 4.3(f)
and (g) thereto:

               (f) The Parties will cooperate in good faith to establish a
mechanism, at no cost to DLC, to provide the POLR Supplier and FE with a means
to Dynamically Schedule Energy between the FE Control Area and PJM West.

               (g) If, in any hour, the sum of the actual POLR Supply Amount (as
defined in the POLR I Agreement) and the actual POLR Supply Amount hereunder is
less than the FE Swap Amount, then DLC shall pay to the POLR Supplier an amount
of dollars equal to the then applicable hourly locational marginal price under
the PJM West Protocols multiplied by the positive difference, if any, between
(x) the amount of Energy delivered by the POLR Supplier to the FE Control Area
during such hour pursuant to the POLR I Agreement and this Agreement and (y) the
actual POLR Supply Amount (as defined in the POLR I Agreement) for such hour
plus the actual POLR Supply Amount hereunder for such hour.

later than three hours prior to the close of the ACAP market then set by the PJM
West Protocols, the POLR Supply Forecasts and the DLC Zone Hourly Forecasts for
the following calendar day. DLC shall provide updates to the POLR Supply
Forecasts and DLC Zone Hourly Forecasts delivered to the POLR Supplier by
delivering to the POLR Supplier a real-time POLR Supply Forecast and DLC Zone
Hourly Forecast for each hour.

               (b) In addition, DLC shall deliver to the POLR Supplier, as often
as is practicable but in no event later than the end of each month, a report
listing known changes in the POLR Supply Amount, as well as any know changes to
the Schedules attached hereto, which changes shall be incorporated into and
become a part of the Schedules to which they relate, subject, however, to the
prior consent of the POLR Supplier to such changes to such Schedules if such
consent is required under this Agreement.

          5.2 Scheduling. On a daily basis, the POLR Supplier shall schedule,
              ----------
pursuant to the FE Protocols, the FE POLR Supply Amounts. On a daily basis, the
POLR Supplier shall schedule, pursuant to the PJM West Protocols, the DLC POLR
Supply Amounts, provided, that any portion of any DLC POLR Supply Amount not
scheduled on a day-ahead basis shall be scheduled, pursuant to the PJM West
Protocols, by the POLR Supplier using day-after E-schedules according to such
rules and procedures as may be then required by the PJM West Protocols. DLC
shall provide the POLR Supplier with a copy of any Dispatch Notice issued
pursuant to the DLC Must-Run Agreements at the same time such Dispatch Notice is
given to the owner(s) of the Cheswick and/or Elrama generating plants. Within
two (2) hours of receipt of any such Dispatch Notice, the POLR Supplier shall
submit to PJM West (with a copy provided simultaneously to DLC of) a revised
schedule incorporating the DLC Must-Run Purchases referenced in such Dispatch
Notice.

          5.3 Reconciliation. Any POLR Energy Imbalance shall be hourly energy
              --------------
imbalance attributable to the POLR Supplier for purposes of calculating Supply
Violation Charges. On a daily basis, no later than the prevailing time deadline
in the PJM West Protocols for internal transactions, the POLR Supplier shall
have completed any E-schedules contemplated by Section 5.2 hereof in respect of
the DLC POLR Supply Amounts for the preceding calendar day and shall deliver to
DLC an FE Tally Sheet in respect of the FE POLR Supply Amounts for the preceding
calendar day. The Parties recognize and agree that POLR Energy Imbalance is
comprised of FE POLR Energy Imbalance and DLC POLR Energy Imbalance and that
separate Supply Violation Charges shall be calculated for any FE POLR Energy
Imbalance and any DLC POLR Energy Imbalance.

thereto:

          (d) In addition to any amounts paid by DLC to the POLR Supplier
pursuant to the foregoing provisions, during the term of the Ancillary Services
Agreement, DLC shall pay to the POLR Supplier all RRRAS Payment Amounts (as

Ancillary Services Agreement by summing the RRRAS Payment Amounts for each day
of a particular calendar month on the twentieth calendar following the last day
of such calendar month and increasing the amount of the Net Billed Generation
Revenue to be paid to the POLR Supplier on such calendar day pursuant to Section
7.1(a) hereof by an amount of dollars equal to such summed RRRAS Payment
Amounts.

     Sections 7.2, 7.3, 7,4, 7.5 and 7.6 are hereby amended and restated in
their entirety as follows:

          7.2 Weekly Invoicing of Preliminary Supplier Charges. DLC shall, on

          7.5 DLC Right to Offset.
              -------------------

               (a) In addition to any other right to offset against payments to
the POLR Supplier under this Agreement, DLC shall have the right to offset any
amounts the POLR Supplier owes DLC pursuant to Sections 7.2, 7.3 and 7.4 hereof
(except for such amounts reasonably disputed by the POLR Supplier) against the
amounts owed by DLC pursuant to Section 7.1 hereof. In doing so, on any
particular day, if an amount is owing to DLC pursuant to Section 7.2, Section
7.3 or Section 7.4 hereof, DLC may retain such portion of the Net Billed
Generation Revenue otherwise owing to the POLR Supplier under Section 7.1 hereof
for such day as an offset in satisfaction thereof; if any such amount owing to
DLC exceeds the Net Billed Generation Revenue otherwise owing to the POLR
Supplier under Section 7.1 hereof for such day, DLC may retain such Net Billed
Generation Revenue as an offset and withhold further payments of Net Billed
Generation Revenue otherwise owing to the POLR Supplier under Section 7.1 hereof
as an offset until the amount owing to DLC pursuant to Sections 7.2, 7.3 and 7.4
has been fully recovered by DLC.

               (b) In addition to the right to offset set forth in Section
7.5(a), if, on any day after reviewing the E-schedules and FE Tally Sheet
described in Section 5.3 hereof attributable to the immediately preceding
calendar day, DLC determines that the Preliminary Supplier Charges for such day
exceed $5 million, such Preliminary Supplier Charges shall become immediately
due from the POLR Supplier and payable to DLC as an offset. In such an instance,
DLC may retain such portion of the Net Billed Generation Revenue otherwise owing
to the POLR Supplier under Section 7.1 hereof for such day equal to such
Preliminary Supplier Charges as an offset in satisfaction thereof; if any such
Preliminary Supplier Charges owing to DLC exceeds the Net Billed Generation
Revenue otherwise owing to the POLR Supplier under Section 7.1 hereof for such
day, DLC may retain such Net Billed Generation Revenue as an offset and withhold
further payments of Net Billed Generation Revenue otherwise owing to the POLR
Supplier under Section 7.1 hereof as an offset until the amount of such
Preliminary Supplier Charges has been fully recovered by DLC.

          7.6 Right to Immediate Payment and to Draw on Letter of Credit. In
              ----------------------------------------------------------
addition to the rights to offset under Section 7.5 hereof, DLC shall further
have the right to immediate payment from the POLR Supplier, and to draw upon the
letter(s) of credit posted by the POLR Supplier under the terms of this
Agreement, in the amounts and under the circumstances provided below:

               (a) If at any time Preliminary Supplier Charges or Supplier
Charges in an amount in excess of $30 million are then due from the POLR
Supplier and payable to DLC under the terms of this Agreement and the POLR
Agreement, DLC shall provide notice of the same to the POLR Supplier and, upon
receipt thereof, the POLR Supplier shall make immediate payment to DLC of the
dollar amount of such Preliminary Supplier Charges or Supplier Charges, as the
case may be, in immediately available funds to the bank account designated by
DLC in Section 15.3 hereof.

               (b) If, within ten (10) days following notice to the POLR
Supplier given by DLC pursuant to Section 7.6(a), DLC has not received payment
in full of the Preliminary Supplier Charges or Supplier Charges so noticed, then
DLC has the right to draw upon the letter(s) of credit posted by the POLR
Supplier under the terms of this Agreement in an amount up to, but not
exceeding, any portion of such Preliminary Supplier Charges or Supplier Charges
then unpaid by the POLR Supplier, and if DLC draws upon such letter(s) of
credit, such letter(s) of credit are insufficient to pay to DLC such Preliminary
Supplier Charges or Supplier Charges and the POLR Supplier fails to replace such
letter(s) of credit with letter(s) of credit in such amounts as are sufficient
to pay to DLC such Preliminary Supplier Charges or Supplier Charges, DLC shall
also have the right to terminate this Agreement upon ten (10) days written
notice to the POLR Supplier.

     Section 7.9 is hereby amended and restated in its entirety as follows:

expiration relating to the POLR Supply Service provided through the date of
termination or expiration of this Agreement.

     Section 9.2(c) is hereby amended and restated in its entirety as follows:

          (c) Following the earliest Rate Class Effective Date hereunder, if:

          (i) the PUC issues an order requiring a change that will directly or
          indirectly reduce or increase the Generation Rates (other than as
          contemplated by the Capacity Agreement) or that will result in any
          other material change to the Retail Tariff, in a manner that adversely
          affects the

                                       12
<PAGE>

          rights or obligations of a Party respecting matters under this
          Agreement so as to cause such Party a Material Adverse Effect,

          (ii) the PUC issues an order requiring a change to the Supplier Tariff
          (other than as contemplated by the Capacity Agreement) in a manner
          that adversely affects the rights or obligations of a Party respecting
          matters under this Agreement so as to cause such Party a Material
          Adverse Effect,

          (iii) the FERC issues an order requiring a change (other than changes
          to Schedule 9B to the OATT) in a manner that adversely affects the
          rights or obligations of a Party respecting matters under this
          Agreement so as to cause such Party a Material Adverse Effect,

          (iv) there is any change in the rates of any Governmental Charges
          imposed on or with respect to the Parties rights or obligations
          hereunder, or in the manner in which any such Governmental Charges are
          imposed, in either case in a manner that adversely affects the rights
          or obligations of a Party respecting matters under this Agreement so
          as to cause such Party a Material Adverse Effect, or

          (v) the PJM West Protocols or FE Protocols are modified in a manner
          that affects the rights and obligations of a Party respecting matters
          under this Agreement so as to cause such Party a Material Adverse
          Effect,

then, the affected Party may deliver written notice of the occurrence of any
such event(s) to the other Party (such notice, a "Renegotiation Notice").
Promptly after the delivery and receipt of a Renegotiation Notice, the Parties
shall, in good faith, attempt to negotiate a mutually satisfactory amendment to
this Agreement to restore the respective rights and obligations of the Parties
under this Agreement as they existed immediately prior to such event(s) or to
achieve another mutually satisfactory result. If within thirty (30) days
following the delivery of any such Renegotiation Notice the Parties fail to
agree upon any such amendment, the affected Party may then terminate the
Agreement by providing the other Party with fifteen (15) days' prior written
notice of such termination. Any amendment to this Agreement negotiated as a
result of a Renegotiation Notice shall be deemed to be retroactively effective
to the date on which the event(s) described in such Renegotiation Notice
occurred; provided, however, that if following any such event, the order giving
rise to such event is no longer in effect (or is modified in a manner described
in clause (i), (ii) or (iii) hereof) by virtue of a decision by a Governmental
Authority that has become final and non-appealable, then any such amendment
shall be of no further force and effect and this Agreement shall be read so as
not to include such amendment (and in the event such order is modified in a
manner described in clause (i), (ii) or (iii) hereof, the Parties may deliver a
Renegotiation Notice with respect thereto as otherwise contemplated hereunder).
Upon any termination pursuant to this Section 9.2(c), neither Party shall have
any further liability to the other Party under this Agreement, except for any
obligations that arose or accrued prior to the effective date of such
termination.

     Capacity Agreement pursuant to Section 6.2(b) thereof, then upon receiving
     such written notice from DLC, the POLR Supplier may, by written notice to
     DLC, designate the effective date of the termination of the Capacity
     Agreement as the termination date of this Agreement. Any such notice to DLC
     must be given, if at all, within ninety (90) days following the POLR
     Supplier's receipt of DLC's notice of the termination of the Capacity
     Agreement. Upon any termination pursuant to this Section 9.2(c), neither

          in Article VII of this Agreement, the following amounts, as
          applicable:

               (a) POLR Energy Imbalance. If the POLR Supplier fails to deliver
                   ---------------------
          to the DLC Zone the POLR Supply Amount for such hour, the POLR
          Supplier shall in the event of an under-delivery, pay to DLC an amount

          Protocols applicable to an over-delivery of an amount of Energy equal
          to the POLR Energy Imbalance (net of any costs DLC incurs in disposing
          of such Energy). For the avoidance of doubt, the POLR Supplier's
          delivery of Energy to the DLC Zone in any given hour shall first be
          allocated to the POLR Supply Amount under the POLR I Agreement and

          the POLR Supplier's failure to deliver the POLR Supply Amount in
          accordance with Section 4.1 hereof causes DLC to Shed Load during any

          DLC as the result of claims, penalties, repairs, expenses or other
          damages resulting from such Shed Load; provided, however, that if
          during any such hour (x) the POLR

          that is not on forced or planned outage and/or forced or planned
          curtailments) to the DLC Control Area (and delivers to DLC a
          certificate executed by a duly authorized officer of the POLR Supplier
          to such effect) and nevertheless fails to deliver the POLR Supply
          Amount and (y) DLC is unable to procure alternative sources of Energy
          in the market sufficient to compensate for the POLR Supplier's
          under-delivery, then the POLR Supplier shall pay to DLC, in addition
          to any amounts otherwise due hereunder, but in lieu of the $1,000 per
          megawatt-hour of Shed Load described above, $100 per megawatt-hour of
          Shed Load attributable to such failure plus any of the aforementioned
          out-of-pocket costs incurred by DLC. For purposes of this Section

          by the PJM West Protocols, the POLR Supply Forecasts and the DLC Zone
          Hourly Forecasts, as applicable, for the following calendar day. DLC
          shall provide updates to the POLR Supply Forecasts and the DLC Zone
          Hourly Forecasts, as applicable, delivered to the POLR Supplier by
          delivering to the POLR Supplier a real-time POLR Supply Forecast and

          immediately due from DLC and netted against any payments owing to DLC
          on such statement of account with any excess amount payable to the
          POLR Supplier by increasing by the amount of any such excess the
          amount of Net Billed Generation Revenue to be paid to the POLR
          Supplier under Section 7.1 hereof on the day that the statement of
          account reflecting such excess is rendered.

               (a) In addition to any other right to offset against payments to
          the POLR Supplier under this Agreement, DLC shall have the right to
          offset any amounts the POLR Supplier owes DLC pursuant to Sections
          7.2, 7.3 and 7.4 hereof (except for such amounts reasonably disputed
          by the POLR Supplier) against the amounts owed by DLC pursuant to
          Section 7.1 hereof. In doing so, on any particular day, if an amount
          is owing to DLC pursuant to Section 7.2, Section 7.3 or Section 7.4
          hereof, DLC may retain such portion of the Net Billed Generation
          Revenue otherwise owing to the POLR Supplier under Section 7.1 hereof
          for such day as an offset in satisfaction thereof; if any such amount
          owing to DLC exceeds the Net Billed Generation Revenue otherwise owing
          to the POLR Supplier under Section 7.1 hereof for such day, DLC may
          retain such Net Billed Generation Revenue as an offset and withhold
          further payments of Net Billed Generation Revenue otherwise owing to
          the POLR Supplier under Section 7.1 hereof as an offset until the
          amount owing to DLC pursuant to Sections 7.2, 7.3 and 7.4 has been
          fully recovered by DLC.

               (b) In addition to the right to offset set forth in Section
          7.5(a), if, on any day after reviewing the E-schedules described in
          Section 5.3 hereof attributable to the immediately preceding calendar
          day, DLC determines that the Preliminary Supplier Charges for such day
          exceed $5 million, such Preliminary Supplier Charges shall become
          immediately due from the POLR Supplier and payable to DLC as an
          offset. In such an instance, DLC may retain such portion of the Net
          Billed Generation Revenue otherwise owing to the POLR Supplier under
          Section 7.1 hereof for such day equal to such Preliminary Supplier
          Charges as an offset in satisfaction thereof; if any such Preliminary
          Supplier Charges owing to DLC exceeds the Net Billed Generation
          Revenue otherwise owing to the POLR Supplier under Section 7.1 hereof
          for such day, DLC may retain such Net Billed Generation Revenue as an
          offset and withhold further payments of Net Billed Generation Revenue
          otherwise owing to the POLR Supplier under Section 7.1 hereof as an
          offset until the amount of such Preliminary Supplier Charges has been
          fully recovered by DLC.

               7.6 Right to Immediate Payment and to Draw on Letter of Credit.
                   -----------------------------------------------------------
          In addition to the rights to offset under Section 7.5 hereof, DLC
          shall further have the right to immediate payment from the POLR
          Supplier, and to draw upon the letter(s) of credit posted by the POLR
          Supplier under the terms of this Agreement, in the amounts and under
          the circumstances provided below:

               (a) If at any time Preliminary Supplier Charges or Supplier
          Charges in an amount in excess of $30 million are then due from the
          POLR Supplier and payable to DLC under the terms of this Agreement and
          the POLR Agreement, DLC shall provide notice of the same to the POLR
          Supplier and, upon receipt thereof, the POLR Supplier shall make

                                       24
<PAGE>

          immediate payment to DLC of the dollar amount of such Preliminary
          Supplier Charges or Supplier Charges, as the case may be, in
          immediately available funds to the bank account designated by DLC in
          Section 15.3 hereof.

               (b) If, within ten (10) days following notice to the POLR
          Supplier given by DLC pursuant to Section 7.6(a), DLC has not received
          payment in full of the Preliminary Supplier Charges or Supplier
          Charges so noticed, then DLC has the right to draw upon the letter(s)
          of credit posted by the POLR Supplier under the terms of this
          Agreement in an amount up to, but not exceeding, any portion of such
          Preliminary Supplier Charges or Supplier Charges then unpaid by the
          POLR Supplier, and if DLC draws upon such letter(s) of credit, such
          letter(s) of credit are insufficient to pay to DLC such Preliminary
          Supplier Charges or Supplier Charges and the POLR Supplier fails to
          replace such letter(s) of credit with letter(s) of credit in such
          amounts as are sufficient to pay to DLC such Preliminary Supplier
          Charges or Supplier Charges, DLC shall also have the right to
          terminate this Agreement upon ten (10) days written notice to the POLR
          Supplier.

          Section 7.9 shall be amended and restated in its entirety as follows:

               7.9 Survival. Notwithstanding any other provision of this
                   --------
          Agreement to the contrary, the provisions of this Article VII, and the
          rights and obligations of the Parties hereunder, shall survive the
          expiration of the term or the termination of this Agreement for the
          purpose of satisfying the rights and obligations of the Parties that
          arose or accrued prior to such termination or expiration relating to
          the POLR Supply Service provided through the date of termination or
          expiration of this Agreement.

          Section 9.2(c) shall be amended and restated in its entirety as
     follows:

          (c) Following the earliest Rate Class Effective Date hereunder, if:

          (i) the PUC issues an order requiring a change that will directly or
          indirectly reduce or increase the Generation Rates (other than as
          contemplated by the Capacity Agreement when initially executed) or
          that will result in any other material change to the Retail Tariff, in
          a manner that adversely affects the rights or obligations of a Party
          respecting matters under this Agreement so as to cause such Party a
          Material Adverse Effect,

          (ii) the PUC issues an order requiring a change to the Supplier Tariff
          (other than as contemplated by the Capacity Agreement when initially

                                       25
<PAGE>

          executed) in a manner that adversely affects the rights or obligations
          of a Party respecting matters under this Agreement so as to cause such
          Party a Material Adverse Effect,

          (iii) the FERC issues an order requiring a change (other than changes
          to Schedule 9B to the OATT) in a manner that adversely affects the
          rights or obligations of a Party respecting matters under this
          Agreement so as to cause such Party a Material Adverse Effect,

          (iv) there is any change in the rates of any Governmental Charges
          imposed on or with respect to the Parties rights or obligations
          hereunder, or in the manner in which any such Governmental Charges are
          imposed, in either case in a manner that adversely affects the rights
          or obligations of a Party respecting matters under this Agreement so
          as to cause such Party a Material Adverse Effect, or

          (v) the PJM West Protocols or FE Protocols are modified in a manner
          that affects the rights and obligations of a Party respecting matters
          under this Agreement so as to cause such Party a Material Adverse
          Effect,

          then, the affected Party may deliver written notice of the occurrence
          of any such event(s) to the other Party (such notice, a "Renegotiation
          Notice"). Promptly after the delivery and receipt of a Renegotiation
          Notice, the Parties shall, in good faith, attempt to negotiate a
          mutually satisfactory amendment to this Agreement to restore the
          respective rights and obligations of the Parties under this Agreement
          as they existed immediately prior to such event(s) or to achieve
          another mutually satisfactory result. If within thirty (30) days
          following the delivery of any such Renegotiation Notice the Parties
          fail to agree upon any such amendment, the affected Party may then
          terminate the Agreement by providing the other Party with fifteen (15)
          days' prior written notice of such termination. Any amendment to this
          Agreement negotiated as a result of a Renegotiation Notice shall be
          deemed to be retroactively effective to the date on which the event(s)
          described in such Renegotiation Notice occurred; provided, however,
          that if following any such event, the order giving rise to such event
          is no longer in effect (or is modified in a manner described in clause
          (i), (ii) or (iii) hereof) by virtue of a decision by a Governmental
          Authority that has become final and non-appealable, then any such
          amendment shall be of no further force and effect and this Agreement
          shall be read so as not to include such amendment (and in the event
          such order is modified in a manner described in clause (i), (ii) or
          (iii) hereof, the Parties may deliver a Renegotiation Notice with
          respect thereto as otherwise contemplated hereunder). Upon any
          termination pursuant to this Section 9.2(c), neither Party shall have
          any further liability to the other Party under this Agreement, except
          for any obligations that arose or accrued prior to the effective date
          of such termination.

          (b) In addition to the foregoing and notwithstanding any other
provision of this Section 15.13 to the contrary, in the event, and only in the
event, that the FE Capacity Agreement is terminated but the Capacity Agreement
is not terminated, this Agreement shall be further amended as set forth below
(provided, however, that immediately upon the termination of the Capacity
Agreement all such further amendments to this Agreement shall be of no further
force or effect and this Agreement shall be read so as not to include any such
further amendments):

          Section 1.1 shall be further amended by restating the following
          definition in its entirety to read as follows:

          "Supplier Charges" means any charges to the POLR Supplier under this
           ----------------
          Agreement, any charges to the POLR Supplier as the "Supplier" under
          the Capacity Agreement, and any charges to the POLR Supplier as the
          "POLR Supplier" under the Ancillary Services Agreement, including
          Supply Violation Charges, Transmission Congestion Charges, ACAP Market
          Transaction Costs (as defined under the Capacity Agreement), Supplier
          ACAP Deficiency Charges (as defined under the Capacity Agreement),
          RRRAS Charge Amounts (as defined under the Ancillary Services
          Agreement, including any negative EGS RRRAS Imbalance Amount described
          thereunder), and shall include any adjustments necessary to account
          for DLC's costs in purchasing Energy for Passthrough Power under the
          Interruptible Service, the payment for which shall be the
          responsibility of the POLR Supplier, and the revenues received by DLC
          from Interruptible Service customers for the incremental charges for
          Energy related to the amount of Passthrough Power actually supplied to
          such customers, which revenues shall be credited to the POLR Supplier
          to the extent such revenues have not been otherwise included in the
          Billed Generation Revenue attributable to such Passthrough Power.

          Section 1.1 shall be further amended to add the following additional
          definitions:

          "Ancillary Services Agreement" means that certain Amended and Restated

           ---------------------------------
          defined in the Capacity Agreement.

                                       27
<PAGE>

          The last sentence of Section 4.2(j) shall be further amended and
          restated in its entirety as follows:

          In addition, DLC agrees to refrain from filing with the PUC any
          request for modification of the Generation Rates (other than (x) as
          contemplated by the Retail Tariff Changes (as defined under the
          Capacity Agreement) together with such changes to the Retail Tariff
          Changes as may have been acceptable to DLC on or prior to the Capacity
          Agreement Effective Date, and (y) a request by DLC for a change in the
          PJM West Surcharge), unless the Parties shall mutually agree
          otherwise.

          (c) Finally, for the avoidance of doubt, and notwithstanding any other
provision of this Section 15.13 to the contrary, in the event that the
conditions to the effectiveness of Section 15.14 of this Agreement have been
satisfied prior to the satisfaction of the conditions to the effectiveness of
this Section 15.13, and subsequent thereto the FE Capacity Agreement is
terminated, then the amendments made pursuant to Section 15.14 of this Agreement
shall be of no further force or effect and this Agreement shall be read so as to
exclude therefrom, for all purposes whatsoever, such amendments, and the
provisions of Section 15.13(a) shall be the sole effective amendments to this
Agreement pursuant to this Article XV.

               15.14 Effect of Termination of Capacity Agreement Only. In the
                     ------------------------------------------------
event that the Capacity Agreement is terminated but the FE Capacity Agreement is
not terminated, this Agreement shall be amended as follows:

          Section 1.1 shall be amended by restating the following definition in
          its entirety:

          "FE Swap Percentage" means sixty-five percent (65%).
           ------------------

          Section 1.1 shall be further amended by amending the definition of
          "Net Billed Generation Revenue" such that clause (ii) of the first
          sentence of such definition is restated to read as follows:

          (ii) DLC's costs attributable to Ancillary Services (except for energy

          termination or expiration of the Ancillary Services Agreement, the
          costs for RRRAS (as defined under the Ancillary Services Agreement)
          are calculated using the rates set forth in Schedule 9B to the OATT as
          in effect on the date of the Ancillary Services Agreement and the
          costs for any other Ancillary Services (except for energy imbalance)
          are calculated using the rates set

                                       28
<PAGE>

          forth in Schedule 9B to the OATT then in effect, and provided further
          that following the termination or expiration of the Ancillary Services
          Agreement, the costs attributable to all Ancillary Services (except
          for energy imbalance) shall be calculated using the rates then set
          forth in Schedule 9B to the OATT then in effect).

          Section 1.1 shall be amended by adding the following definition
          thereto:

          "Congestion Payment" means, beginning only after the effective date of
           ------------------

          date of the termination of the Capacity Agreement occurs) as an
          additional amount that is due and payable to the POLR Supplier
          pursuant to Section 7.3 hereof. The Parties recognize and agree that
          no Congestion Payment is required while the Capacity Agreement remains
          in effect.

          Section 7.3 shall be amended and restated in its entirety to read as
     follows:

               7.3 Monthly Settlement Statement of Account for Preliminary

          Supplier Charges. DLC shall, within ten (10) days following the end of

          each calendar month, provide a statement of account to the POLR
          Supplier setting forth all Preliminary Supplier Charges invoiced
          during the immediately preceding calendar month and adjusting such
          Preliminary Supplier Charges, as necessary, based on the information
          then available to DLC. Payments owing to DLC reflected on any
          statement of account rendered pursuant to this Section 7.3 shall be
          immediately due from the POLR Supplier and payable to DLC by offset
          pursuant to Section 7.5. Credits owing to the POLR Supplier reflected
          on any statement of account rendered pursuant to this Section 7.3, or
          any amounts payable to the POLR Supplier as a Congestion Payment as of
          such date, shall be immediately due from DLC and netted against any
          payments owing to DLC on such statement of account with any excess
          amount payable to the POLR Supplier by increasing by the amount of any
          such excess the amount of Net Billed Generation Revenue to be paid to
          the POLR Supplier under Section 7.1 hereof on the day that the

 2/ Any revenues collected under this rider are subject to the state tax
-
adjustment under Rider 10.

On an annual basis, or such more frequent basis as the Company may from time to
time select, the Company will adjust any Grid Management, Start-Up, and Other
Charges used to calculate the PJM West Surcharge as may be necessary to fully
reconcile revenues collected from customers and costs for start-up and operating
costs and similar fees imposed on the Company by joining PJM West (and to
account for any additional payment then required to be made by the Company to
its POLR Supplier pursuant to the Pennsylvania Public Utility Commission
authorization of              at page    ). Such adjustments shall take into
                 ------------         ---

Charges used to calculate the PJM West Surcharge.

Every adjustment made pursuant to the above paragraph shall be submitted to the
Commission annually, or on such more frequent basis as the Company may from time
to time select, and if any such adjusted PJM West Surcharge is less than the one
then in effect the Company will, and if any such adjusted PJM West Surcharge is
more than the one then in effect the Company may, accompany such adjustment with
a Tariff or supplement to reflect such adjusted PJM West Surcharge, the
effective date of which, shall be ten (10) days after the filing of the Tariff
or supplement reflecting such adjusted PJM West Surcharge.

                                   SCHEDULE 4
                             SUPPLIER TARIFF CHANGES

                    Proposed New Provision in Supplier Tariff
                    -----------------------------------------

(a) The RRRAS Charge Amount for an EGS for a day shall be that share of the
daily charges assessed by PJM to DLC for the provision of Reactive Supply and
Voltage Control from Generation Sources Service, Regulation and Frequency
Response Service, Operating Reserve - Spinning Reserve Service, and Operating
Reserve - Supplemental Reserve Service attributable to the EGS' share of DLC
Zone load.

(b) If an EGS schedules or bids load into PJM on a day-ahead basis in an amount
equivalent in each hour to the DLC Zone forecast for the EGS for that day, then
the RRRAS Charge Amounts for the EGS load for that day shall be the sole
responsibility of DLC;

(c) Alternatively, if an EGS schedules or bids load into PJM on a day-ahead
basis in an amount that differs in any hour from the DLC Zone forecast for the
EGS for that day, then the RRRAS Charge Amounts for the EGS load related to the
DLC Zone forecast for that day shall be the responsibility of DLC, while the EGS
shall be responsible for any imbalances due to EGS schedules or bids differing
from the DLC Zone forecast. These charges (or credits) shall be calculated
pursuant to sub-section (d) below.

(d) The amount for which the EGS is responsible or that the EGS is credited
shall be the "EGS RRRAS Imbalance Amount." The EGS RRRAS Imbalance Amount will
be calculated hourly.

The EGS RRRAS Imbalance Amount will be calculated in each hour as follows:

Definitions
-----------

For each hour, the following quantities and prices will be used to determine the
EGS RRRAS Imbalance Amount:

     DLC DA = DLCs Day-Ahead Forecast for the EGS in MWhs
     EGS DA = EGS Day-Ahead Energy Schedule for the in MWhs
     EGS RT = EGS Real-Time Energy Usage in MWhs
     DA ASP = PJM West Day-ahead Operating ReservesPrice in $/MWhs
     RT ASP = PJM West Balancing Operating Reserves Price in $/MWhs

     RRRAS IBA = EGS RRRAS Imbalance Amount in $

Calculation (Each Hour)
-----------------------

i) If EGS DA = DLC DA

     Then RRRAS IBA = 0
<PAGE>

ii) If EGS DA is greater than or less than the DLC DA, then the RRRAS IBA shall
be the sum of the following payments and/or credits in each hour:

1. Difference between the EGS RT and DLC DA
-------------------------------------------

     .    If the EGS RT is greater than the DLC DA, then the EGS shall receive a
          credit for that difference between the EGS RT and DLC DA at the RT
          ASP.

     .    If the DLC DA is greater than the EGS RT, then the EGS shall receive a
          credit for that difference between the DLC DA and the EGS RT at the RT
          ASP.

2. Differences between the EGS DA and EGS RT
--------------------------------------------

     .    If the EGS RT is greater than the EGS DA, then the EGS shall pay an
          imbalance charge for that difference between the EGS RT and EGS DA at
          the RT ASP.

     .    If the EGS DA is greater than the EGS RT, then the EGS shall pay an
          imbalance charge for that difference between the EGS DA and the EGS RT
          at the RT ASP.

3. Difference between the EGS DA and DLC DA
-------------------------------------------

     .    If the EGS DA is greater than the DLC DA then the EGS shall pay an
                           ------
          imbalance charge for that difference at the DA ASP

     .    If the EGS DA is less than the DLC DA, then the EGS shall receive a
                           ----
          credit for that difference at the DA ASP
          -----

Example - EGS DA > DLC DA

<PAGE>

Example - EGS DA * DLC DA

* = Less than

                                    [GRAPHIC]

(e)  DLC shall bill or credit the EGS monthly for each day's EGS RRRAS Imbalance
     Amount. These imbalance charges or credits will be in addition to any
     ancillary service charges billed to an EGS under DLC's schedule 9A.

(f)  The EGS shall grant DLC access to their day-ahead schedule information for
     the purposes of calculating the RRRAS imbalance amount.

<PAGE>

     term of this Agreement an amount of RRRAS necessary to serve, as determined
     by the PJM West Protocols, the DLC Zone. The POLR Supplier shall either
     obtain the quantity of RRRAS necessary to serve the DLC Zone or supply such
     quantity from the POLR Supplier's owned resources, in either case only in
     accordance with the PJM West Protocols.

3.2  Designated Agent. In coordination with the POLR Supplier, DLC will take
     ----------------
     such actions as PJM requires to permit the POLR Supplier to be DLC's
     Designated Agent in PJM, if necessary, for the purpose of supplying RRRAS
     to DLC and/or obtaining RRRAS from PJM for DLC in accordance with this
     Agreement.

3.4  Other Services. The POLR Supplier shall have no obligation under this
     --------------
     Agreement to provide Energy Imbalance service or Scheduling, System Control
     and Dispatch service to DLC.

     4 Payment and Charges

4.1  Payment for RRRAS. Provided that the POLR Supplier has complied with its
     -----------------
     obligations hereunder, the purchase price for all amounts of RRRAS
     purchased by DLC pursuant to this Agreement for a particular day shall be
     the RRRAS Payment Amount for such day. All RRRAS Payment Amounts due and
     payable hereunder shall be paid by DLC to the POLR Supplier on a monthly
     basis by summing the RRRAS Payment Amounts for each day of a particular
     calendar month on the twentieth calendar day following the last day of such
     calendar month and increasing the amount of Net Billed Generation Revenue
     (as defined under the POLR II Agreement) to be paid to the POLR Supplier on
     such calendar day by the amount of dollars equal to such summed RRRAS
     Payment Amounts. If the POLR II Agreement (as defined under the Capacity
     Agreement) is terminated, then the Parties shall negotiate in good faith
     such amendments to the Capacity Agreement as shall be necessary to provide
     that all payments due either Party hereunder are to be invoiced by DLC and
     paid and/or offset by the appropriate Party, as necessary, on a monthly
     basis, under the terms of the Capacity Agreement, as contemplated by
     Section 6.2(d) of the Capacity Agreement. If the POLR II Agreement (as
     defined under the Capacity Agreement) and the Capacity Agreement are
     terminated then the Parties shall negotiate in good faith such amendments
     to this Agreement as shall be necessary to provide that all payments due
     either Party hereunder are to be invoiced by DLC and paid

                                       9
<PAGE>

     and/or offset by the appropriate Party, as necessary, on a monthly basis,
     under the terms of this Agreement.

4.2  Charges Associated with RRRAS. The POLR Supplier shall be responsible for
     -----------------------------
     all charges associated with RRRAS incurred by DLC under the PJM West
     Protocols beginning on the Effective Date until the termination of this
     Agreement and shall pay to DLC on each day beginning on the Effective Date
     through the termination of this Agreement an amount of dollars equal to the
     amount of such charges then incurred by DLC (each such amount, an "RRRAS
     Charge Amount"), which RRRAS Charge Amounts shall be immediately due and
     payable by the POLR Supplier to DLC as a Supplier Charge (as defined under
     the POLR II Agreement) pursuant to the terms of the POLR II Agreement. The
     Parties agree that the RRRAS Charge Amount shall include all charges
     assessed to or imposed on DLC under the PJM West Protocols, including any
     penalties, as a result of the POLR Supplier's failure to supply DLC with
     the necessary quantity of RRRAS. The Parties also agree that the POLR
     Supplier shall be responsible, at POLR Supplier's cost, for any heightened
     RRRAS obligations imposed upon DLC as a result of the POLR Supplier's
     failure to supply DLC with the necessary quantity of RRRAS.

4.3  Supplier Tariff Changes. DLC will use its best efforts to cause revisions
     -----------------------
     to the Duquesne Light Company Electric Generation Supplier Tariff (together
     with such changes thereto as are acceptable to the Parties hereto), as set
     forth on Schedule 4 to the Capacity Agreement, to be accepted by the PUC.
     Notwithstanding anything in Schedule 4 to the Capacity Agreement to the
     contrary, and for the avoidance of doubt, the Parties recognize and agree
     that the POLR Supplier will responsible for the charges identified in
     Schedule 4 to the Capacity Agreement as the responsibility of DLC, and that
     the POLR Supplier will be entitled to receive the payments identified in
     Schedule 4 to the Capacity Agreement as payable to DLC, which charges or
     credits shall be paid by or credited to the POLR Supplier as part of the
     RRRAS Charge Amount set forth in Section 4.2.

4.4  Adjustment to RRRAS Payment Amount and RRRAS Charge Amount. The EGS RRRAS
     ----------------------------------------------------------
     Imbalance Amount (as defined in Schedule 4 to the Capacity Agreement) as
     calculated for an EGS and billed to the EGS monthly, if positive, shall be
     added to the RRRAS Payment Amount due and payable hereunder by DLC to the
     POLR Supplier three (3) business days after such EGS RRRAS Imbalance Amount
     is received from an EGS; provided, however, that DLC will pursue collection
     of the EGS RRRAS Imbalance Amount pursuant to the procedures available to
     DLC under DLC's Electric

                                       10
<PAGE>

     Generation Supplier Coordination Tariff. If the EGS RRRAS Imbalance Amount
     for an EGS is negative, credits associated therewith shall be charged to
     the POLR Supplier as RRRAS Charge Amounts pursuant to Section 4.2 hereof.

4.5  No Change. The rates for service specified herein shall remain in effect
     ---------
     for the term of this Agreement, and shall not be subject to change through
     application to the FERC pursuant to the provisions of Section 205 of the
     Federal Power Act or otherwise absent the agreement of both Parties hereto.

     5    Scheduling

5.1  Communication. The DLC dispatch office shall maintain communication with
     -------------
     the POLR Supplier's dispatch office as needed.

5.2  Good Utility Practice. Each Party agrees to adhere to Good Utility Practice
     ---------------------
     and to specifically adhere to the applicable operating policies, criteria
     and/or guidelines of PJM, NERC, ECAR and all other regional or subregional
     requirements.

     6    Force Majeure

6.1  Force Majeure. Notwithstanding anything in this Agreement to the contrary,
     -------------
     neither Party shall be liable in damages, or otherwise responsible to the
     other Party, for its failure to perform or observe any of its obligations
     under this Agreement if and only to the extent that it is unable to so
     perform or is prevented from performing by an event of Force Majeure;
     provided, however, that to the extent that the POLR Supplier fails to
     supply RRRAS in accordance with Section 3.1 hereof, whether as a result of
     an event of Force Majeure or for any other reason, the provisions of
     Section 4.2 hereof shall apply to such failure. The Parties recognize and
     agree that an event of Force Majeure will not relieve any Party of its
     obligation to make payments when due hereunder.

6.2  Definition of Force Majeure. The term "Force Majeure" as used herein means
     ---------------------------
     those causes beyond the reasonable control of the Party affected that, by
     the exercise of reasonable diligence, including Good Utility Practice, such
     Party is unable to prevent, avoid, mitigate, or overcome, including an act
     of God, labor dispute (including a strike), act of the public enemy, war,
     civil disturbance, insurrection, riot, fire (unless resulting from the
     fault or negligence of the Party asserting Force Majeure), storm or flood,
     lightning, explosion (unless resulting from the fault or negligence of the
     Party asserting

                                       11
<PAGE>

     Force Majeure), order, government decree or rule, regulation or restriction
     imposed by governmental, military or lawfully-established civilian
     authorities, or any other cause of a similar nature beyond such Party's
     reasonable control. Events that cause a change in the market value of
     Energy, the POLR Supplier's generation costs or otherwise affect the POLR
     Supplier's cost of performance under this Agreement shall not be considered
     Force Majeure events.

6.3  Force Majeure Procedures. Upon the occurrence of an event of Force Majeure,
     ------------------------
     the Party affected by such event shall (a) provide prompt written notice of
     such Force Majeure event to the other Party, including an estimation of its
     expected duration and the probable impact on the performance of its
     obligations hereunder; (b) exercise all reasonable efforts in accordance
     with Good Utility Practice to continue to perform its obligations under
     this Agreement; (c) expeditiously take action to correct or cure the event
     or condition excusing performance, provided, however, that settlement of
     labor disputes will be completely within the sole discretion of the Party
     affected by such labor dispute; (d) exercise all reasonable efforts to
     mitigate or limit damages to the other Party; and (e) provide prompt notice
     to the other Party of the cessation of the event or condition giving rise
     to its excuse from performance. Any obligation under this Agreement shall
     be suspended only to the extent caused by such Force Majeure event and only
     during the continuance of any inability of performance caused by such Force
     Majeure event but for no longer period.

     7    Default, Renegotiation and Termination

7.1  Event of Default. Unless excused by Force Majeure, each of the following
     ----------------
     events shall be considered an Event of Default:

     (a)  The material breach by either Party of any agreement, covenant or
          obligation under this Agreement; provided that such breach is not
          caused by the material breach of the other Party, and provided further
          that, if such breach is curable, a default shall not occur until the
          Party in breach has failed to cure such breach within thirty (30) days
          after receipt of written notice thereof by the non-defaulting Party;

     (b)  The discovery that any representation or warranty made by a Party
          hereunder was false or misleading in any material respect when made
          that is not cured within thirty (30) days and which has a material
          adverse effect on the ability of the Party making such representation
          or warranty to perform its obligations hereunder;

                                       12
<PAGE>

     (c)  The filing of an involuntary petition in bankruptcy against either
          Party or the appointment of a receiver or liquidator or trustee for
          either Party or of any substantial part of the property of a Party,
          provided that if such Party is working diligently to have such
          petition, receiver, liquidator or trustee stayed, dismissed or
          discharged, a default shall not occur unless such petition, receiver,
          liquidator or trustee is not stayed, dismissed or discharged within
          thirty (30) days;

     (d)  The entry of a decree adjudicating a Party or any substantial part of
          the property of a Party bankrupt or insolvent, provided that if such
          Party is working diligently to have such decree discharged or stayed,
          a default shall not occur unless such decree is continued undischarged
          and unstayed for a period of thirty (30) days;

     (e)  The filing of a voluntary petition in bankruptcy under any provision
          of any federal or state bankruptcy law by a Party or against it; or

     (f)  The failure of a Party to pay the other Party undisputed amounts owed
          within ten (10) days after receiving written notice from a Party that
          any such amount is overdue.

7.2  Termination.
     -----------

          (a)  Upon the occurrence of an Event of Default, the non-defaulting
               Party may terminate this Agreement by providing one hundred
               twenty (120) days' written notice to the defaulting Party of a
               specified date of termination; provided, however, that upon the
               occurrence of an Event of Default specified in Section 7.1 (c),
               (d) and (e) hereof, the non-defaulting Party may terminate this
               Agreement by delivering to the defaulting Party a written notice
               of termination, which termination shall be effective upon the
               defaulting Party's receipt of such notice. The non-defaulting
               Party may exercise all such rights and remedies as may be
               available to it to recover damages caused by such Event of
               Default.
          (b)  Following the Effective Date, if:
               (i) the PUC issues an order modifying the Retail Tariff Changes
               (together with such changes thereto as may have been acceptable
               to DLC on or prior to the Effective Date) in a manner that
               materially impairs DLC's ability to recover from its customers
               the amounts paid to the POLR Supplier under this Agreement,

                                       13
<PAGE>

               (ii) either (x) the PUC issues an order modifying the Supplier
               Tariff Changes (together with such changes thereto as may have
               been acceptable to the Parties on or prior to the Effective
               Date), (y) the FERC issues an order or (z) the PJM West Protocols
               are modified, in any such case, in a manner that affects the
               rights or obligations of a Party respecting matters under this
               Agreement so as to cause such Party a Material Adverse Effect, or
               (iii) the Capacity Agreement is terminated,
          then, the affected Party may deliver written notice of the occurrence
     of any such event(s) to the other Party (such notice, a "Renegotiation
     Notice"). Promptly after the delivery and receipt of a Renegotiation
     Notice, the Parties shall, in good faith, attempt to negotiate a mutually
     satisfactory amendment to this Agreement to restore the respective rights
     and obligations of the Parties under this Agreement as they existed
     immediately prior to such event(s) or to achieve another mutually
     satisfactory result. If within thirty (30) days following the delivery of
     any such Renegotiation Notice that notices an event described in clause
     (i), (ii) or (iii) hereof the Parties fail to agree upon any such
     amendment, the affected Party may then terminate the Agreement by providing
     the other Party with one hundred twenty (120) days' prior written notice of
     such termination. Any amendment to this Agreement negotiated as a result of
     a Renegotiation Notice shall be deemed to be retroactively effective to the
     date on which the event(s) described in such Renegotiation Notice occurred;
     provided, however, that if following any such event, the order giving rise
     to such event is no longer in effect (or is modified in a manner described
     in clause (i) or (ii) hereof) by virtue of a decision by a Governmental
     Authority or governing body that has become final and non-appealable, then
     any such amendment shall be of no further force and effect and this
     Agreement shall be read so as not to include such amendment (and in the
     event such order is modified in a manner described in clause (i) or (ii)
     hereof, the Parties may deliver a Renegotiation Notice with respect thereto
     as otherwise contemplated hereunder). Upon any termination pursuant to this
     Section 7.2(b), neither Party shall have any further liability to the other
     Party under this Agreement, except for any obligations that arose or
     accrued prior to the effective date of such termination.

7.3  Additional Remedies. The POLR Supplier acknowledges and specifically agrees
     -------------------
     that its obligations under this Agreement are essential to ensure the
     reliability of the DLC Zone; that breach of the POLR Supplier's obligations
     may result in irreparable harm and damage to DLC which cannot adequately be
     compensated by a monetary award; and that, as a consequence thereof, DLC
     shall, in addition to any other remedy to which DLC may be entitled by

                                       14
<PAGE>

     reason of the POLR Supplier's breach of this Agreement, be entitled to seek
     and obtain temporary, preliminary and permanent injunctive relief from any
     court or Governmental Authority of competent jurisdiction restraining the
     POLR Supplier from committing or continuing any breach of this Agreement.

     8    Indemnification

8.1  DLC's Indemnification. DLC shall indemnify, hold harmless and defend the
     ---------------------
     POLR Supplier, its parent, its Affiliates, and its and their successors,
     officers, directors, employees, shareholders, agents, contractors,
     subcontractors, invitees and successors, from and against any and all
     claims, demands, suits, obligations, payments, liabilities, costs, losses,
     judgments, damages and expenses (including the costs and expenses of any
     and all actions, suits, proceedings, assessments, judgments, settlements,
     and compromises relating thereto, reasonable attorneys' and expert fees and
     reasonable disbursements in connection therewith) for damage to property,
     injury to or death of any Person, including the POLR Supplier's employees,
     DLC's employees and their Affiliates' employees, or any third parties, to
     the extent caused wholly or in part by any act or omission, negligent or
     otherwise, by DLC or its officers, directors, employees, agents,
     contractors, subcontractors and invitees arising out of or connected with
     DLC's performance or breach of this Agreement, or the exercise by DLC of
     its rights hereunder. In furtherance of the foregoing indemnification and
     not by way of limitation thereof, DLC hereby waives any defense it
     otherwise might have under applicable workers' compensation laws.

8.2  POLR Supplier's Indemnification. The POLR Supplier shall indemnify, hold
     -------------------------------
     harmless and defend DLC, its parent, Affiliates, and its and their
     successors, officers, directors, employees, shareholders, agents,
     contractors, subcontractors, invitees and successors, from and against any
     and all claims, demands, suits, obligations, payments, liabilities, costs,
     losses, judgments, damages and expenses (including the costs and expenses
     of any and all actions, suits, proceedings, assessments, judgments,
     settlements, and compromises relating thereto reasonable attorneys' and
     expert fees and reasonable disbursements in connection therewith) for
     damage to property, injury to or death of any Person, including DLC's
     employees, the POLR Supplier's employees and their Affiliates' employees,
     or any third parties, to the extent caused wholly or in part by any act or
     omission, negligent or otherwise, by the POLR Supplier or its officers,
     directors, employees, agents, contractors, subcontractors and invitees
     arising out of or connected with the POLR Supplier's performance or breach
     of this Agreement, or the exercise by the POLR Supplier of its rights
     hereunder. In furtherance of the foregoing

                                       15
<PAGE>

     indemnification and not by way of limitation thereof, the POLR Supplier
     hereby waives any defense it otherwise might have under applicable workers'
     compensation laws.

8.3  Indemnification Procedures. Any Party seeking indemnification under this
     --------------------------
     Agreement shall give the other Party notice of such claim promptly but in
     any event on or before the earlier of the fifteenth (15th) day after the
     Party's actual knowledge of such claim or action or the ninetieth (90th)
     day from commencement of the event or circumstance giving rise to the
     claim. Such notice shall describe the claim in reasonable detail, and shall
     indicate the amount (estimated if necessary) of the claim that has been, or
     may be sustained by, said Party. To the extent that the other Party will
     have been actually and materially prejudiced as a result of the failure to
     provide such notice, such notice will be a condition precedent to any
     liability of the other Party under the indemnification provisions contained
     in this Agreement. Neither Party may settle or compromise any claim for
     which indemnification is sought under this Agreement without the prior
     consent of the other Party, provided that such consent shall not be
     unreasonably withheld or delayed.

8.4  Survival. The indemnification obligations of each Party under this Article
     --------
     for acts or occurrences that occur prior to expiration, termination, or
     cancellation of this Agreement shall survive and continue in full force and
     effect regardless of whether this Agreement expires or terminates, or is
     canceled, surrendered or completed. Such indemnification obligations shall
     not be limited in any way by any limitation on insurance, by the amount or
     types of damages, or by any compensation or benefits payable by the Parties
     under worker's compensation acts, disability benefit acts or other employee
     acts, or otherwise.

     9 Dispute Resolution

9.1  Disputes. A Party with a claim or dispute under this Agreement shall submit
     --------
     to the other Party a notification of such claim or dispute within sixty
     (60) days of the date on which the Party knew, or should have known, of the
     occurrence of the circumstances that gave rise to the claim or the question
     or issue in dispute, and shall provide the Administration Committee (as
     defined in the POLR II Agreement) with a copy of such notification. Any
     such notification shall be in writing and shall include a concise statement
     of the claim or the issue or question in dispute, a statement of the
     relevant facts and documentation to support the claim. The Administration
     Committee (as defined in the POLR II Agreement) shall use its good faith
     best efforts to resolve the claim or dispute within thirty (30) days after
     its receipt of a

                                       16
<PAGE>

          notification specifying the claim, issue or question in dispute. If
          the Administration Committee (as defined in the POLR II Agreement) is
          unable to do so, the Parties shall refer the claim or dispute to their
          respective senior management. Subject to Section 7.4 hereof, if, after
          using their good faith best efforts to resolve the dispute, the
          Parties' senior management cannot resolve the dispute within thirty
          (30) days, the Parties may, if they both so agree in writing, utilize
          the alternative dispute resolution procedures set forth below in
          Sections 7.2 and 7.3 hereof.

     9.2  Arbitration. Any arbitration initiated under this Agreement shall be
          -----------
          conducted before a single neutral arbitrator appointed by the Parties
          within thirty (30) days of receipt by respondent of the demand for
          arbitration. If the Parties are unable to agree on an arbitrator, such
          arbitrator shall be appointed by the American Arbitration Association.
          Unless the Parties agree otherwise, the arbitrator shall be an
          attorney or retired judge with at least fifteen (15) years of
          experience and shall not have any current or past substantial business
          or financial relationships with any Party to the arbitration. In
          addition, if possible, the arbitrator shall have significant system
          operations experience in the electric industry. Unless otherwise
          agreed, the arbitration shall be conducted in accordance with the
          American Arbitration Association's Commercial Arbitration Rules, then
          in effect, in Pittsburgh, Pennsylvania. Any arbitration proceedings,
          decision or award rendered hereunder and the validity, effect and
          interpretation of this arbitration agreement shall be governed by the
          Federal Arbitration Act of the United States, 9 U.S.C. Sections 1 et
          seq.

     9.3  Arbitration Terms. The arbitration shall, if possible, be concluded
          -----------------
          not later than six (6) months after the date that it is initiated. The
          arbitrator shall be authorized only to interpret and apply the
          provisions of this Agreement or any related agreements entered into
          under this Agreement and shall have no power to modify or change any
          of the above in any manner. The arbitrator shall have no authority to
          award punitive or multiple damages or any damages inconsistent with
          this Agreement. The arbitrator shall, within thirty (30) days of the
          conclusion of any hearing, unless such time is extended by agreement
          of the Parties, notify the Parties in writing of his or her decision,
          stating his or her reasons for such decision and separately listing
          his or her findings of fact and conclusions of law. The decision of
          the arbitrator rendered in such a proceeding shall be final and
          binding on the Parties. Judgment on any award made by the arbitrator
          may be entered in any court having jurisdiction.

                                       17
<PAGE>

     9.4  FERC Jurisdiction. Notwithstanding any other provision of this
          -----------------
          Agreement to the contrary, nothing in this Agreement shall preclude,
          or be construed to preclude, any Party from filing a petition or
          complaint with FERC with respect to any arbitrable claim over which
          FERC has jurisdiction. In such a case, the other Party may request
          FERC to reject or to waive jurisdiction. If FERC rejects or waives
          jurisdiction with respect to all or a portion of such claim, the
          portion of such claim not so accepted by FERC may be resolved through
          arbitration, as provided in this Agreement. To the extent that FERC
          asserts or accepts jurisdiction over such claim, the decision,
          findings of fact or order of FERC shall be final and binding, subject
          to judicial review under the Federal Power Act, and any arbitration
          proceedings that may have commenced with respect to such claim prior
          to the assertion or acceptance of jurisdiction by FERC shall be
          terminated.

          10 Confidentiality

     10.1 Generally.
          ---------

     (a)  Each Party (i) shall maintain the confidentiality of all information
          provided to it by the other Party under the terms of this Agreement,
          (ii) shall not disclose such information to third parties (other than
          its Affiliates, advisors, and parties prospectively providing
          financing and risk management) without the prior written consent of
          the other Party, unless otherwise provided hereunder, and (iii) agrees
          to use such information only for such purposes and in such manner as
          is contemplated by the terms of this Agreement. Notwithstanding the
          foregoing, each Party shall be permitted to use any information
          provided to it by the other Party under the terms of this Agreement in
          support of any claim or counterclaim respecting an alleged breach of
          such other Party's obligations under this Agreement.
     (b)  Upon the other Party's prior written approval (which shall not be
          unreasonably withheld), either Party may provide information provided
          to it by the other Party under the terms of this Agreement to the PUC,
          FERC or other Governmental Authority with jurisdiction, as may be
          necessary, to obtain required regulatory approvals or to comply
          generally with any applicable Law. In such an instance, the disclosing

               maintenance of its Connection Equipment in accordance with Good
               Utility Practice or this Amended Agreement, DLC shall give
               Generating Company written notice to take corrective action. Such
               written notice shall be provided by DLC as soon as practicable
               upon such determination. If Generating Company fails to initiate
               corrective action promptly, and in no event later than seven (7)
               days after the delivery of such notification, and if in DLC's
               reasonable judgment leaving Generating Company's facilities
               connected with the Transmission System would create an Emergency
               Condition, DLC may, with as much prior oral notification to
               Generating Company as practicable, open the connection between
               Generating Company and DLC until appropriate corrective actions
               have been completed by Generating Company, as verified by DLC.
               Any such interruption as permitted by this paragraph shall not
               constitute an event of Force Majeure. DLC's judgment with regard
               to an interruption of service under this paragraph shall be made
               pursuant to Good Utility Practice and subject to Section 3.1
               hereto. In the case of such interruption, DLC shall immediately
               confer with Generating Company regarding the conditions causing
               such interruption and its recommendation concerning timely
               correction thereof.

                                        -35-
<PAGE>

               Both Parties shall act promptly to correct the condition leading
               to such interruption and to restore the connection.

          (b)  If Generating Company reasonably determines that (i) any of DLC's
               Connection Equipment fails to perform in a manner consistent with
               Good Utility Practice or this Agreement, or (ii) DLC has failed
               to perform proper testing or maintenance of its Connection
               Equipment in accordance with Good Utility Practice or this
               Amended Agreement, Generating Company shall give DLC written
               notice to take corrective action. Such written notice shall be
               provided by Generating Company as soon as practicable upon such
               determination. If DLC fails to initiate corrective action
               promptly, and in no event later than seven (7) days after the
               delivery of the notification, and if in Generating Company's
               reasonable judgment leaving the Transmission System connected
               with Generating Company's facilities would create an Emergency
               Condition, Generating Company may, with as much prior oral
               notification to DLC as practicable, open the connection between
               Generating Company and DLC, as verified by Generating Company.
               Any such interruption as permitted by this paragraph shall not
               constitute an event of Force Majeure. Generating Company's
               judgment with regard to this interruption of service under this
               paragraph shall be made pursuant to Good Utility Practice. In the
               case of such interruption, Generating Company shall immediately
               confer with DLC regarding the conditions causing such
               interruption and its recommendation concerning timely correction
               thereof. Both Parties shall act promptly to correct the condition
               leading to such interruption and to restore the connection.

     any requirement of any Governmental Authority, NERC, ECAR, PJM or any
     successor of any of them, regarding the right of DLC to require reduced or
     increased generation of the Units in the event of an Emergency Condition.
     In addition, and without limiting the generality of the foregoing,
     Generating Company shall operate its facilities to mitigate an Emergency
     Condition when requested by DLC or PJM. Such operation may call for full or
     partial interruption of the Connection Equipment either by manual or
     automatic means. Notification of Emergency Conditions shall be completed in
     accordance with the notification requirements set forth in Article 9.

3.9  Generating Company shall, at its expense, maintain real-time communications

5.2  Meter and related equipment shall be as follows:

                                      -39-
<PAGE>

     (a)  Each generating unit connected to the Transmission System shall have
          revenue quality metering facilities installed to provide direct
          readings of the Unit's bi-directional net real and reactive power and
          energy output. The metering instrument transformers used to measure
          the Unit's net output shall be installed on or compensated to the high
          side (transmission voltage side) of the generator step-up transformer,
          unless otherwise agreed by the Parties.

     (b)  All plant auxiliary power transformers (non-generator step-down
          transformers) and lines directly connected to the Transmission System
          shall have metering facilities installed to provide bi-directional
          real and reactive power and energy flow. Metering instrument
          transformers shall be connected to or compensated to the high side

          must be capable of providing the minimum data mutually agreed by the
          Parties.

5.3  Notwithstanding Section 5.2, Generating Company and DLC agree that, if the
     metering facilities and the Connection Point are not at the same physical
     location, the metering data shall be compensated, as mutually agreed by the
     Parties, to record delivery of electricity in a manner that accounts for
     the total (load plus no-load) electrical energy losses occurring between
     the metering points and the Connection Points when the Units are delivering
     energy to the Transmission System, when DLC is delivering station service
     electricity to Generating Company for the Units, or for any other use.

5.4  Remote data acquisition of the Unit's meters shall be performed by polling
     of an RTU by System Control's Energy Management System computer at a scan
     rate to be reasonably determined by DLC. The data collected shall include
     the bi-directional instantaneous values of megawatts and megavars and
     bi-directional accumulated megawatthours and megavarhours for each Unit,
     and such other data as may be mutually agreed by the Parties. System
     Control may adopt such measures as are necessary for security of the
     metering facilities and data.

5.5  Generating Company shall provide reasonable access, in accordance with

5.6  Unless otherwise mutually agreed, all meters shall be sealed, and the seals
     shall be broken only by Qualified Personnel of Generating Company upon
     occasions when the meters are to be inspected, tested, adjusted or
     recalibrated in accordance with Good Utility Practice and in the presence
     of duly authorized Qualified Personnel of DLC.

5.7  All metering equipment installed pursuant to this Article 5 shall be
     routinely tested by Generating Company in accordance with Good Utility
     Practice. DLC may request one meter testing for each meter annually at no
     cost to DLC. DLC may request any number of additional meter tests and
     compensate the Generating Company for the actual cost to test the meters.
     DLC may make unannounced inspections to conduct its own test of the meters,
     provided that the Generating Company will be allowed to observe such tests.
     If the metering facilities are found not to be accurate or are otherwise
     defective, they shall be repaired, adjusted, or replaced by Generating
     Company, and meter readings for the period of inaccuracy shall be corrected
     so far as corrections can be reasonably ascertained.

5.8  Generating Company shall maintain and make available for review by DLC in a
     timely manner records of all meter tests and maintenance conducted pursuant
     to this Article 5.

     in accordance with Section 27.8.

12.4 The rate of interest on any amount not paid when due shall be equal to the
     Interest Rate in effect at the time such amount became due. Interest on
     delinquent amounts shall be calculated from the due date of the bill to the
     date of payment. When payments are made by mail, bills shall be considered
     as having been paid on the date of receipt by the other Party. Nothing
     contained in this Article is intended to limit either Party's remedies
     under Article 21 of this Amended Agreement.

12.5 Payment of an invoice shall not relieve the paying Party from any
     responsibilities or obligations it has under this Amended Agreement, nor
     shall such payment constitute a waiver of any claims arising hereunder.

12.6 If all or part of any bill is disputed by a Party, that Party shall
     promptly pay the amount that is not disputed and provide the other Party a
     reasonably detailed written explanation of the basis for the Dispute
     pursuant to Article 25. The disputed amount shall be paid into an
     independent escrow account pending resolution of the Dispute, at which time
     the prevailing Party shall be entitled to receive the disputed amount, as
     finally determined to be payable, along with interest accrued at the
     Interest Rate through the date on which payment is made, within ten (10)
     business days of such resolution.

12.7 Within two (2) years following a calendar year, during normal business
     hours, Generating Company and DLC shall have the right to audit each
     other's accounts and records pertaining to transactions under this Amended
     Agreement that occurred during such calendar year at the offices where such
     accounts and records are maintained; provided that the audit shall be
     limited to those portions of such accounts and records that reasonably
     relate to the services provided to the other Party under this Amended
     Agreement for said calendar year. The Party being audited shall be entitled
     to review the audit report and any supporting materials. To the extent that
     audited information includes Confidential Information, the auditing Party
     shall keep all such information confidential pursuant to Article 20 and
     FERC Order Nos. 888 and 889, and any successors thereto.

          Governmental Authorities applicable to Generating Company's compliance
          with this Amended Agreement.

14.3 Representations of Both Parties. The representations and warranties in
     -------------------------------
     Sections 14.1.4 and 14.2.4 shall continue in full force and effect for the
     Term of this Amended Agreement.

     ARTICLE 15 Force Majeure

15.1 Notwithstanding anything in this Amended Agreement to the contrary, neither
     Generating Company nor DLC shall be liable in damages, or otherwise
     responsible to the other Party, for its failure to perform or observe any
     of its obligations under this Amended Agreement, if and only to the extent
     that it is unable to so perform or is prevented from performing by an event
     of Force Majeure. An event of Force Majeure does not relieve any Party of
     its obligation to make timely payments hereunder.

15.2 The term "Force Majeure" as used herein means those causes beyond the
     reasonable control of the Party affected, which by the exercise of
     reasonable diligence, including Good Utility Practice, that Party is unable
     to prevent, avoid, mitigate, or overcome, including the following: any act
     of God, labor dispute (including a strike), act of the public enemy, war,
     civil disturbance, insurrection, riot, fire, storm or flood, lightning,
     explosion, order, government decree or rule, regulation or restriction
     imposed by governmental, military or lawfully-established civilian
     authorities, or any other cause of a similar nature beyond a Party's
     reasonable control that prevents performance under this Amended Agreement.
     Neither the cost to maintain the Facility or the Transmission System nor
     any mechanical or electrical breakdown or failure of machinery or plant
     owned or operated by Generating Company or DLC due to normal wear and tear
     on such machinery or plant or due to the manner in which such machinery or
     plant has been operated shall be deemed an event of Force Majeure.

15.3 Each Party shall have the obligation to operate in accordance with Good
     Utility Practice at all times and to use Due Diligence to overcome and
     remove any cause of failure to perform.

15.4 If a Party relies on the occurrence of an event or condition described
     above as a basis for being excused from performance of its obligation under
     this Amended Agreement, then the Party relying on the event or condition
     shall: (i) provide prompt

                                      -52-
<PAGE>

     written notice of such Force Majeure event to the other Party, giving an
     estimate of its expected duration and the probable impact on the
     performance of its obligations hereunder; (ii) exercise all reasonable
     efforts to continue to perform its obligations under this Amended
     Agreement; (iii) expeditiously take action to correct or cure the event or
     condition excusing performance; provided, however, that settlement of
     strikes or other labor disputes will be completely within the sole
     discretion of the Party affected by such strike or labor dispute; (iv)
     exercise all reasonable efforts to mitigate or limit damages to the other
     Party; and (v) provide prompt notice to the other Party of the cessation of
     the event or condition giving rise to its excuse from performance. All
     performance obligations hereunder shall be extended by a period equal to
     the period of inability to perform caused by such Force Majeure event.

15.5 If a Party responding to a Force Majeure event has the ability to obtain,
     for additional expenditures, expedited material deliveries or labor
     production which would allow a response to the event in a manner that is
     above and beyond Good Utility Practice, such a response could shorten the
     duration of the event, and a shorter duration of the event could lessen the
     economic hardship of the other Party, the Party responding to the event
     may, at its discretion, present the other Party with the option of funding
     the expenditures for expediting material deliveries or labor production in
     an effort to reduce the duration of the event and economic hardship. Each
     such opportunity will be negotiated on a case-by-case basis by the Parties.

     ARTICLE 16 Liability

16.1 Except to the extent of the other Party's negligence or willful misconduct
     (or that of its employees, agents, contractors, subcontractors or
     invitees), each Party shall be responsible for all physical damage to or
     destruction of the property, equipment and/or facilities owned by it and
     its Affiliates, regardless of who brings the claim and regardless of who
     caused the damage, and shall not seek recovery or reimbursement from the
     other Party for such damage; but in any such case DLC and Generating
     Company will exercise Due Diligence to remove the cause of any disability
     at the earliest practicable time.

16.2 To the fullest extent permitted by law and notwithstanding other provisions
     of this Amended Agreement, in no event shall DLC, its Affiliates, or any of
     their respective officers, directors, employees, agents, successors or
     assigns be liable to Generating Company, whether in contract, warranty,
     tort, negligence, strict liability, or otherwise, for special, indirect,
     incidental, multiple, consequential (including, without limitation,
     replacement power costs, lost profits or revenues, and lost business
     opportunities), or punitive damages, related to or resulting from
     performance or nonperformance of this

                                      -53-
<PAGE>

     Amended Agreement or any activity associated with or arising out of this
     Amended Agreement.

16.3 To the fullest extent permitted by law and notwithstanding other provisions
     of this Amended Agreement, in no event shall Generating Company, its
     Affiliates, or any of their respective officers, directors, employees,
     agents, successors or assigns be liable to DLC, whether in contract,
     warranty, tort, negligence, strict liability, or otherwise, for special,
     indirect, incidental, multiple, consequential (including, without
     limitation, replacement power costs, lost profits or revenues, and lost
     business opportunities), or punitive damages, related to or resulting from
     performance or nonperformance of this Amended Agreement or any activity
     associated with or arising out of this Amended Agreement.

16.4 No Party shall be liable to another Party for any action that it takes in
     responding to an Emergency Condition, so long as such action is made in
     good faith, is consistent with Good Utility Practice, and is not contrary
     to the directives of PJM with respect to such Emergency Condition.

16.5 The provisions of this Article 16 shall survive termination, cancellation,
     suspension, completion or expiration of this Amended Agreement.

     ARTICLE 17 Indemnification

17.1 Generating Company's Indemnification. Subject to the provisions of Sections
     ------------------------------------
     16.1, 16.2 and 16.3, Generating Company shall indemnify, hold harmless and
     defend DLC, its parent, its Affiliates, and its and their successors,
     officers, directors, employees, shareholders, agents, contractors,
     subcontractors, invitees and successors, from and against any and all
     claims, demands, suits, obligations, payments, liabilities, costs, losses,
     judgments, damages and expenses (including the reasonable costs and
     expenses of any and all actions, suits, proceedings, assessments,
     judgments, settlements, and compromises relating thereto, reasonable
     attorneys' and expert fees and reasonable disbursements in connection
     therewith) for damage to property, injury to or death of any person,
     including DLC's employees, Generating Company's employees and their
     Affiliates' employees, or any third parties, to the extent caused wholly or
     in part by any act or omission, negligent or otherwise, by Generating
     Company or its officers, directors, employees, agents, contractors,
     subcontractors and invitees arising out of or connected with Generating
     Company's performance or breach of this Amended Agreement, or the exercise
     by Generating Company of its rights hereunder. In furtherance of the
     foregoing

                                      -54-
<PAGE>

     indemnification and not by way of limitation thereof, Generating Company
     hereby waives any defense it otherwise might have under applicable workers'
     compensation laws.

     17.2 DLC's Indemnification. Subject to the provisions of Sections 16.1,
          ---------------------
          16.2 and 16.3 DLC shall indemnify, hold harmless and defend Generating
          Company, its parent, Affiliates, and successors, and their officers,
          directors, employees, shareholders, agents, contractors,
          subcontractors, invitees and successors, from and against any and all
          claims, demands, suits, obligations, payments, liabilities, costs,
          losses, judgments, damages and expenses (including the reasonable
          costs and expenses of any and all actions, suits, proceedings,
          assessments, judgments, settlements, and compromises relating thereto
          reasonable attorneys' and expert fees and reasonable disbursements in
          connection therewith) for damage to property, injury to or death of
          any person, including Generating Company's employees, DLC's employees
          and their Affiliates' employees, or any third parties, to the extent
          caused wholly or in part by any act or omission, negligent or
          otherwise, by DLC or its officers, directors, employees, agents,
          contractors, subcontractors and invitees arising out of or connected
          with DLC's performance or breach of this Amended Agreement, or the
          exercise by DLC of its rights hereunder. In furtherance of the
          foregoing indemnification and not by way of limitation thereof, DLC
          hereby waives any defense it otherwise might have under applicable
          workers' compensation laws.

     17.3 Indemnification Procedures. Any Party seeking indemnification under
          --------------------------
          this Amended Agreement shall give the other Party notice of such claim
          promptly but in any event on or before the earlier of the tenth (10th)
          day after the Party's actual knowledge of such claim or action or the
          ninetieth (90th) day from commencement of the event or circumstance
          giving rise to the claim. Such notice shall describe the claim in
          reasonable detail, and shall indicate the amount (estimated if
          necessary) of the claim that has been, or may be sustained by, said
          Party. To the extent that the other Party will have been actually and
          materially prejudiced as a result of the failure to provide such
          notice, such notice will be a condition precedent to any liability of
          the other Party under the provisions for indemnification contained in
          this Amended Agreement. Neither Party may settle or compromise any
          claim for which indemnification is sought under this Amended Agreement
          without the prior consent of the other Party; provided, however, said
          consent shall not be unreasonably withheld or delayed.

     ARTICLE 18 Insurance

                                      -55-
<PAGE>

18.1 The Parties agree to maintain, at their own cost and expense, fire,
     liability, worker's compensation, and other forms of insurance relating to
     their property and facilities in the manner, and amounts, and for the
     durations set forth in Exhibit 2 to this Amended Agreement, as both Parties
     may, from time-to-time, agree to amend. Each Party may require the other
     Party to maintain coverage for five years on all policies written on a
     "claims made" basis.

18.2 Every contract of insurance providing the coverages required in Exhibit 2
     shall include provisions or endorsements (i) stating that such insurance is
     primary insurance with respect to the interest of the other Party and that
     any insurance maintained by the other Party is excess and not contributory
     insurance required hereunder, and (ii) providing that no reduction,
     cancellation or expiration of the policy shall be effective until ninety
     (90) days from the date written notice thereof is actually received by the
     other Party. Upon a Party's receipt of any notice of reduction,
     cancellation or expiration, that Party shall immediately provide written
     notice thereof to the other Party.

18.3 Each Party and its Affiliates shall be named as additional insureds on the
     general liability insurance policies of the other Party set forth in
     Exhibit 2 as their interests may appear with respect to this Amended

     Date during the term of this Amended Agreement, each Party shall provide to
     the other Party, properly executed and current certificates of insurance
     with respect to all insurance policies required to be maintained by such
     Party under this Amended Agreement. Certificates of insurance shall provide
     the following information:

          (a)  Name of insurance company, policy number and expiration date.

          (b)  The coverage required and the limits on each, including the
               amount of deductibles or self-insured retentions, which shall be
               for the account of the Party maintaining such policy.

          (c)  A statement indicating that the other Party shall receive at
               least thirty (30) days prior written notice of cancellation or
               expiration of a policy, or reduction of liability limits with
               respect to a policy, and

          (d)  A statement indicating that the other Party and its Affiliates
               have been named as additional insureds.

                                      -56-
<PAGE>

18.5 At a Party's request, in addition to the foregoing certifications, the
     other Party shall deliver to the first Party a copy of each insurance
     policy, certified as a true copy by an authorized representative of the
     issuing insurance company.

18.6 Each Party shall have the right to inspect the original policies of
     insurance applicable to this Amended Agreement at the other Party's place
     of business during regular business hours.

     ARTICLE 19 Several Obligations

19.  Except where specifically stated in this Amended Agreement to be otherwise,
     the duties, obligations and liabilities of the Parties are intended to be
     several and not joint or collective. Nothing contained in this Amended
     Agreement shall ever be construed to create an association, trust,
     partnership, or joint venture or to impose a trust or partnership duty,
     obligation or liability or agency relationship on or with regard to either
     Party. Each Party shall be individually and severally liable for its own
     obligations under this Amended Agreement.

     ARTICLE 20 Confidentiality

20.1 Certain information provided by each Party (the "Disclosing Party") to the
     other Party (the "Receiving Party") pursuant to the provisions of this
     Agreement may be considered confidential and/or proprietary ("Confidential
     Information"). To be considered confidential, such information must be
     clearly marked "Confidential Information." If disclosed orally, such
     information shall be clearly identified as confidential and such status
     shall be promptly thereafter confirmed in writing.

20.2 The Receiving Party agrees not to disclose Confidential Information to any
     third party not a Representative of the Receiving Party absent advance
     written consent of the Disclosing Party, except as may be necessary to
     enforce the terms of this Amended Agreement, provided that the Receiving
     Party uses reasonable efforts to maintain the confidentiality of such
     information in any proceeding or suit to enforce this Amended Agreement.
     The Receiving Party further agrees that, with respect to Confidential
     Information, it shall (a) restrict disclosure of Confidential Information
     solely to its Representatives on a need-to-know basis; and (b) advise those
     Representatives of their obligations with respect to the Confidential
     Information.

20.3 Confidential Information shall not be deemed to include information which:

                                      -57-
<PAGE>

          (a)  is or becomes generally available to the public other than as a
               result of a disclosure by the Receiving Party;

          (b)  was available to the Receiving Party on a non-confidential basis
               prior to its disclosure by the Disclosing Party; or

          (c)  becomes available to the Receiving Party on a non-confidential
               basis from a person other than the Disclosing Party or its
               Representative who is not otherwise bound by a confidentiality
               agreement with Disclosing Party or its Representative, or is
               otherwise not under any obligation to Disclosing Party or its
               Representative not to disclose the information to the Receiving
               Party.

20.4 The Receiving Party shall treat any Confidential Information with at least
     the same degree of care regarding its secrecy and confidentiality as the
     Receiving Party's similar information is treated within the Receiving
     Party's organization. The Receiving Party shall notify the Disclosing Party
     of any unauthorized disclosure to third parties that the Receiving Party
     discovers, and Receiving Party shall endeavor to prevent further such
     disclosures. Receiving Party will be responsible for any breach of the
     terms of this Article 20 by Receiving Party's Representatives.

20.5 In the event that Receiving Party is requested, pursuant to or as required
     by applicable law or regulation, by legal process, to disclose any
     Confidential Information, the Receiving Party shall provide the Disclosing
     Party with prompt notice of such request or requirement in order to enable
     Disclosing Party to seek an appropriate protective order or other remedy;
     and to consult with Disclosing Party with respect to Disclosing Party
     taking steps to resist or narrow the scope of such request or legal
     process. The Receiving Party agrees not to oppose any action by the
     Disclosing Party to obtain a protective order or other appropriate remedy.
     In the event that no such protective order or other remedy is obtained, the
     Receiving Party shall furnish only that portion of the Confidential
     Information which the Receiving Party is advised by counsel is legally
     required. In any such event, Receiving Party shall use its commercially
     reasonable efforts to ensure that all Confidential Information so disclosed
     will be accorded confidential treatment.

20.6 The Parties agree that remedies at law may be inadequate to protect each
     other in the event of a breach of this Article 20, and the Receiving Party
     hereby in advance agrees that the Disclosing Party shall be entitled to
     seek and obtain, without proof of actual damages, temporary, preliminary
     and permanent injunctive relief from any court or Governmental Authority of
     competent jurisdiction restraining Receiving Party from committing or
     continuing any breach of this Article 20.

20.7 The confidentiality obligations of each Party under this Article 20 shall
     continue in full force and effect for a period of two (2) years following
     the termination of this Amended Agreement.

     ARTICLE 21 Remedies

21.1 In the event that either Party (the "Delinquent Party") fails to make full
     payment of the undisputed portion of any invoice rendered under this
     Amended Agreement on or before the due date, the other Party (the
     "Non-Delinquent Party") shall give the Delinquent Party notice in writing
     of such delinquency, and the Delinquent Party will have thirty (30)
     business days from the date of its receipt of such written notice to cure
     such delinquency. In the event the Delinquent Party fails to make full
     payment of the delinquent amount (including interest accrued at the
     Interest Rate) within such 30-day period, the Delinquent Party will be in
     default. In the event of a default by Generating Company, DLC shall have
     the right to apply to the FERC to terminate service under this Amended
     Agreement.

21.2 If either Party fails to fulfill obligations under this Amended Agreement
     (in such event, a "Defaulting Party") and such failure could adversely
     affect the use, operation, or economic benefit of the Transmission System
     or Generating Company's Facilities, including without limitation the
     Connection Equipment, or the regional network, the other Party (the
     "Non-Defaulting Party"), following thirty (30) days' prior written notice
     (which specifies the nature of such failure in reasonable detail) to the
     Defaulting Party (except in cases of emergencies in which case only such
     notice as shall be reasonably practicable in the circumstances), the
     Defaulting Party shall be deemed in default, and the Non-Defaulting Party
     may, but shall not be obligated to, apply to the FERC to terminate service
     under this Amended Agreement.

21.3 The enumeration of the foregoing remedies shall not be deemed to be a
     waiver of any other remedies at law or in equity to which the
     Non-Delinquent Party or the Non-Defaulting Party is legally entitled.

     ARTICLE 22 Term

22.1 This Agreement shall become effective as of the Effective Date (as defined
     under the Capacity Agreement) and shall continue in full force and effect
     as long as the Facilities are connected to the Transmission System, unless
     modified by written agreement of the Parties (such period, the "Term").

22.2 For Connection Service and voltage and reactive control requirements set
     forth in Articles 2, 3, and 4:

          (a)  if (i) FERC, any state or state regulatory commission, implements
               a change in any law, regulation, rule or practice, or (ii) DLC or
               PJM upon approval of FERC, implements a change in any regulation,
               rule or practice, which change materially affects or is
               reasonably expected to materially affect DLC's provision of
               Connection Service to Generating Company or voltage and reactive
               control requirements set forth in Articles 2, 3 and 4, the
               Parties shall negotiate in good faith to determine the
               amendments, if any, to this Amended Agreement necessary to
               conform the terms of Connection Service or voltage or reactive
               control requirements to such change, and DLC shall file such
               amendments with the FERC; provided that in negotiating such
               amendments the Parties shall attempt, in good faith, to preserve,
               to the extent reasonably possible, the bargain initially struck
               in this Amended Agreement; and provided further that no such
               amendment shall require any payment to be made by Generating
               Company to DLC for the connection of the Units to the
               Transmission System in existence on the Auction Closing Date; and

          (b)  in addition, on a mutually convenient date after the date hereof
               and thereafter as requested by either Party during the Term of
               this Amended Agreement, the Parties shall meet to discuss the
               impact on the terms of Connection Service of any changes in the
               OATT, or any rule or practice of NERC, ECAR, PJM, or any other
               regulatory agency.

22.3 The applicable provisions of this Amended Agreement shall continue in
     effect after cancellation or termination hereof to the extent necessary to
     provide for final billings, billing adjustments and payments pertaining to
     liability and indemnification obligations arising from acts or events that
     occurred while this Amended Agreement was in effect.

     ARTICLE 23 Assignment/Change in Corporate Identity

23.1 Neither this Amended Agreement nor any of the rights, interests, or
     obligations hereunder shall be assigned, except to an Affiliate or
     successor of DLC that owns or operates all or any portion of the
     Transmission System (including an independent system operator or
     independent transmission company), or to an Affiliate of Generating Company
     that owns the Facilities or any subsequent purchaser of any of the
     Facilities, by any Party hereto, including by operation of law, without the
     prior written consent of the

                                      -60-
<PAGE>

     other Party, said consent not to be unreasonably withheld. Any assignment
     of this Amended Agreement in violation of the foregoing shall be, at the
     option of the non-assigning Party, void.

          (a)  Notwithstanding the foregoing, Generating Company or its
               permitted assignee may assign, transfer, pledge or otherwise
               dispose of its rights and interests hereunder to a trustee,
               lending institution, or any Person for the purposes of financing
               or refinancing the Facility, including upon or pursuant to the
               exercise of remedies under such financing or refinancing, or by
               way of assignments, transfers, conveyances of dispositions in
               lieu thereof; provided, however, that no such assignment or
               disposition shall relieve or in any way discharge Generating
               Company or such permitted assignee from the performance of its
               duties and obligations under this Amended Agreement. DLC agrees
               to execute and deliver such documents as may be reasonably
               necessary to accomplish any such assignment, transfer,
               conveyance, pledge or disposition of rights hereunder for
               purposes of the financing or refinancing of the Facility, so long
               as DLC's rights under this Amended Agreement are not thereby
               materially altered, amended, diminished or otherwise impaired.

          (b)  Notwithstanding the foregoing, Generating Company may assign its
               obligations hereunder in order to facilitate Generating Company
               obtaining or maintaining exempt wholesale generator status so
               long as Generating Company provides written notice to DLC of any
               such assignment.

          (c)  Notwithstanding the foregoing, either Party may assign this
               Amended Agreement to a successor to all or substantially all of
               the assets of such Party by way of merger, consolidation, sale or
               otherwise, provided such successor assumes and becomes liable for
               all of such Party's duties and obligations hereunder.

23.2 No assignment or transfer of rights or obligations under this Amended
     Agreement by Generating Company shall relieve Generating Company from full
     liability and financial responsibility for the performance thereof after
     any such transfer or assignment unless and until the transferee or assignee
     shall agree in writing to assume the obligations and duties of Generating
     Company under this Amended Agreement and DLC has consented in writing to
     such assumption; said consent not to be unreasonably withheld.
     Notwithstanding the foregoing, an assignment by the Generating Company to
     an Affiliate as contemplated in Section 23.1 shall relieve the Generating
     Company from full liability and financial responsibility, effective on the
     date that Affiliate assumes ownership of the Facilities.

                                      -61-
<PAGE>

23.3 Except as set forth in Section 23.1 above, no assignment or transfer of
     rights or obligations under this Amended Agreement by DLC shall relieve DLC
     from full liability and financial responsibility for the performance
     thereof after any such transfer or assignment unless and until the
     transferee or assignee shall agree in writing to assume the obligations and
     duties of DLC under this Amended Agreement and Generating Company has
     consented in writing to such assumption; said consent not to be
     unreasonably withheld.

23.4 If either Party terminates its existence as a corporate entity by merger,
     acquisition, sale, consolidation or otherwise, or if all or substantially
     all of such Party's assets are transferred to another person or business
     entity, without complying with Sections 23.2 and 23.3 above, the other
     Party shall have the right, enforceable in a court of competent
     jurisdiction, to enjoin the first Party's successor from using the property
     in any manner that interferes with, impedes, or restricts such other
     Party's ability to carry out its ongoing business operations, rights and
     obligations.

23.5 This Amended Agreement and all of the provisions hereof are binding upon,
     and inure to the benefit of, the Parties and their respective successors
     and permitted assigns.

     ARTICLE 24 Subcontractors

24.1 Nothing in this Amended Agreement shall prevent the Parties from utilizing
     the services of subcontractors as they deem appropriate; provided, however,
     the Parties agree that, where applicable, all said subcontractors shall
     comply with the terms and conditions of this Amended Agreement.

24.2 The creation of any subcontract relationship shall not relieve the hiring
     Party of any of its obligations under this Amended Agreement. Each Party
     shall be fully responsible to the other Party for the acts and/or omissions
     of any subcontractor it hires as if no subcontract had been made. Any
     obligation imposed by this Amended Agreement upon the Parties, where
     applicable, shall be equally binding upon and shall be construed as having
     application to any subcontractor.

24.3 Each Party shall be liable for, indemnify, and hold harmless the other
     Party, its Affiliates and their officers, directors, employees, agents,
     servants and assigns from and against any and all claims, demands, or
     actions from the first-mentioned Party's subcontractors, and shall pay all
     costs, expenses and legal fees associated therewith and all judgments,
     decrees and awards rendered therein.

                                      -62-
<PAGE>

24.4 No subcontractor is intended to be or shall be deemed a third-party
     beneficiary of this Amended Agreement.

24.5 To the extent of the responsibility and liability Generating Company has
     agreed to assume in Article 16 above, and to the fullest extent permitted
     by law, Generating Company shall require its subcontractors to indemnify
     and hold harmless and defend DLC, its parent and Affiliates and their
     respective officers, directors, employees, agents and assigns from and
     against any and all claims and/or liability for damage to property, injury
     to or death of any person, including DLC's employees, Generating Company's
     employees and their respective Affiliates' employees, or any other
     liability incurred by DLC or its parent or Affiliates including all
     expenses, legal or otherwise, to the extent caused by any act or omission,
     negligent or otherwise, by said subcontractor and/or its officers,
     directors, employees, agents and assigns arising out of or connected with
     the operation of DLC's and its Affiliates' or Generating Company's and its
     Affiliates' facilities, equipment and property described in this Amended
     Agreement, regardless of whether caused in part by a Party indemnified
     hereunder.

24.6 To the extent of the responsibility and liability DLC has agreed to assume
     in Article 16 above, and to the fullest extent permitted by law, DLC shall
     require its subcontractors to indemnify and hold harmless and defend
     Generating Company, its parent and Affiliates and their respective
     officers, directors, employees, agents and assigns from and against any and
     all claims and/or liability for damage to property, injury to or death of
     any person, including DLC's employees, Generating Company's employees and
     their respective Affiliates' employees, or any other liability incurred by
     Generating Company or its parent or Affiliates including all expenses,
     legal or otherwise, to the extent caused by any act or omission, negligent
     or otherwise, by said subcontractor and/or its officers, directors,
     employees, agents and assigns arising out of or connected with the
     operation of DLC's and its Affiliates' or Generating Company's and its
     Affiliates' facilities, equipment and property described in this Amended
     Agreement, regardless of whether caused in part by a Party indemnified
     hereunder.

24.7 The obligations under this Article 24 shall not be limited in any way by
     any limitation on subcontractor's insurance.

24.8 Each Party shall require its subcontractors to comply with all federal and
     state laws regarding insurance requirements and shall maintain standard and
     ordinary insurance coverages.

     ARTICLE 25 Dispute Resolution

                                      -63-
<PAGE>

25.1 Any claim or dispute which either Party may have against the other arising
     out of or relating to this Amended Agreement or the breach, termination or
     validity thereof (any such claim or dispute, a "Dispute") shall be
     submitted in writing to the other Party. The submission of any Dispute
     shall include a concise statement of the question or issue in dispute,
     together with a statement listing the relevant facts and documentation that
     support the claim. In the event that Representatives of DLC and Generating
     Company are unable in good faith to satisfactorily resolve their
     disagreement within thirty (30) days from the receipt of notice of the
     Dispute, either Party may by written notice to the other refer the Dispute
     to their respective senior management.

25.2 If any Dispute arising hereunder is not resolved within thirty (30) days
     after notice thereof to the other Party, either Party may demand in writing
     the submission of the Dispute to binding arbitration in Pittsburgh,
     Pennsylvania. Any arbitration initiated under this Amended Agreement shall
     be conducted before a single neutral arbitrator appointed by the Parties
     within thirty (30) days of receipt by respondent of the demand for
     arbitration. If the Parties are unable to agree on an arbitrator, such
     arbitrator shall be appointed by the American Arbitration Association.
     Unless the Parties agree otherwise, the arbitrator shall be an attorney or
     retired judge with at least fifteen (15) years of experience, and shall not
     have any current or past substantial business or financial relationships
     with any Party to the arbitration. If possible, the arbitrator shall have
     experience in the electric utility industry. Unless otherwise agreed, the
     arbitration shall be conducted in accordance with the American Arbitration
     Association's Commercial Arbitration Rules then in effect. Any arbitration
     proceedings, decision or award rendered hereunder and the validity, effect
     and interpretation of this arbitration agreement shall be governed by the
     Federal Arbitration Act of the United States, 9 U.S.C. Sections 1 et seq.

25.3 The arbitration shall, if possible, be concluded not later than six (6)
     months after the date that it is initiated. The arbitrator shall be
     authorized only to interpret and apply the provisions of this Amended
     Agreement or any related agreements entered into under this Amended
     Agreement and shall have no power to modify or change any of the above in
     any manner. The arbitrator shall have no authority to award punitive or
     multiple damages or any damages inconsistent with this Amended Agreement.
     The arbitrator shall within thirty (30) days of the conclusion of the
     hearing, unless such time is extended by agreement of all Parties, notify
     the Parties in writing of his or her decision, stating his or her reasons
     for such decision and separately listing his or her findings of fact and
     conclusions of law. The decision of the arbitrator rendered in such a
     proceeding shall be final and binding on the Parties. Judgment on the award
     may be entered upon it in any court having jurisdiction.

                                      -64-
<PAGE>

25.4 Nothing in this Amended Agreement shall preclude, or be construed to
     preclude, any Party from filing a petition or complaint with FERC with
     respect to any arbitrable claim over which FERC has jurisdiction. In such
     case, the other Party may request FERC to reject or to waive jurisdiction.
     If FERC rejects or waives jurisdiction with respect to all or a portion of
     the claim, the portion of the claim not so accepted by FERC shall be
     resolved through arbitration, as provided in this Amended Agreement. To the
     extent that FERC asserts or accepts jurisdiction over the claim, the
     decision, finding of fact or order of FERC shall be final and binding,
     subject to judicial review under the Federal Power Act, and any arbitration
     proceedings that may have commenced with respect to the claim prior to the
     assertion or acceptance of jurisdiction by FERC shall be terminated. Each
     of the Parties hereto irrevocably waives its right to a jury trial with
     respect to any action or claim arising out of any dispute in connection
     with this Amended Agreement or the transactions contemplated hereby.

     ARTICLE 26 Additional Cost Responsibilities

     26.  If Generating Company requests an upgrade to the Transmission System,
          Generating Company will be responsible for its share of the cost of
          the upgrade pursuant to the OATT.

     ARTICLE 27 Miscellaneous Provisions

27.1 This Amended Agreement shall constitute the entire agreement between the
     Parties hereto relating to the subject matter hereof, and all previous
     agreements, discussions, communications, and correspondence with respect to
     the subject matter hereof not set forth in this Amended Agreement are of no
     force and effect.

27.2 In the event that it is deemed necessary to amend this Amended Agreement,
     the Parties will attempt to agree upon such amendment and will submit such
     mutually agreed upon amendment(s) to the FERC for filing and acceptance.
     However, either Party shall have the right at any time to propose an
     amendment to the provisions of this Amended Agreement relating to the
     amount that Party charges the other Party to provide service under this
     Amended Agreement by filing an amendment with the FERC and serving such
     amendment on the other Party. Such an amendment shall become effective as a
     change of rate under Section 205 of the Federal Power Act upon acceptance
     by FERC. Notwithstanding the above, no application will be made to FERC by
     DLC to recover any costs associated with the connection of the Units to the
     Transmission System in existence on the Auction Closing Date.

<PAGE>

27.3 No failure or delay on the part of DLC or Generating Company in exercising
     any of its rights under this Amended Agreement, no partial exercise by
     either Party of any of its rights under this Amended Agreement, and no
     course of dealing between the Parties shall constitute a waiver of the
     rights of either Party under this Amended Agreement. Any waiver shall be
     effective only by a written instrument signed by the Party granting such
     waiver, and such shall not operate as a waiver of, or estoppel with respect
     to, any subsequent failure to comply therewith.

27.4 Nothing in this Amended Agreement, express or implied, is intended to
     confer on any other person except the Parties hereto any rights, interests,
     obligations or remedies hereunder.

27.5 In the event that any clause or provision of this Amended Agreement or any
     part hereof shall be held to be invalid, void, or unenforceable by any
     court or governmental authority of competent jurisdiction, said holding or
     action shall be strictly construed and shall not affect the validity or
     effect of any other provision hereof, and the Parties shall endeavor in
     good faith to replace such invalid or unenforceable provisions with a valid
     and enforceable provision which achieves the purposes intended by the
     Parties to the greatest extent permitted by law.

27.6 The Parties hereto agree to execute and deliver promptly, at the expense of
     the Party requesting such action, any and all other and further
     instruments, documents and information which may be reasonably requested in
     order to effectuate the transactions contemplated hereby. The Parties agree
     to cooperate and assist each other in acquiring any regulatory approval
     necessary to effectuate this Amended Agreement.

27.7 The Article and section headings herein are inserted for convenience only
     and are not to be construed as part of the terms hereof or used in the
     interpretation of this Amended Agreement.

27.8 In the event an ambiguity or question of intent or interpretation arises,
     this Amended Agreement shall be construed as if drafted jointly by the
     Parties and no presumption or burden of proof shall arise favoring or
     disfavoring any Party by virtue of authorship of any of the provisions of
     this Amended Agreement. Any reference to any federal, state, local, or
     foreign statute or law shall be deemed also to refer to all rules and
     regulations promulgated thereunder, unless the context requires otherwise.
     The word "including" in this Amended Agreement shall mean including without
     limitation.

               partnership power and authority to own, lease and operate its
               properties and to carry on its business as presently conducted or
               contemplated. Orion Midwest is duly qualified and in good
               standing as a foreign corporation authorized to transact business
               and to own and lease property in each jurisdiction in which the
               nature of the business conducted by it or the character or
               location of the properties owned or leased by it requires such
               qualification. Orion Midwest is not in violation of any term of
               its certificate of

                                      -9-

               judgment, decree, order, statute, rule or governmental regulation
               applicable to it, which would have a material adverse effect on
               DLC.

          7.1.2 Authorization and Validity of Agreement. Orion Midwest has the
                ---------------------------------------
               full partnership power and authority to execute and deliver this
               Agreement, to perform its obligations hereunder and to consummate

               performance of this Agreement, the performance of the obligations
               hereunder and the consummation of the transactions contemplated
               hereby have been duly authorized by all necessary partnership
               action of Orion Midwest. This Agreement has been duly executed
               and delivered by Orion Midwest and constitutes a valid and
               binding obligation of Orion Midwest, enforceable against it in
               accordance with its terms, except that the enforcement hereof and
               thereof may be limited by bankruptcy, insolvency, reorganization,
               moratorium or other similar laws now or hereafter in effect
               relating to creditors rights generally and general principles of
               equity (regardless of whether enforceability is considered in a
               proceeding at law or in equity).

          7.1.3 Government and Third-Party Approvals. Except for those already
                ------------------------------------
               obtained or made, no consent, approval or authorization of or
               filing, registration or qualification with any Governmental
               Authority or any Person (including any Third Party) is required
               by or with respect to Orion Midwest in connection with the
               execution, delivery or performance of this Agreement by Orion
               Midwest and the consummation of the transactions contemplated
               hereby.

                -----------------------------------
               performance of this Agreement will not (i) conflict with or

               to which Orion Midwest is a party or by which Orion Midwest or
               any of its assets may be bound, except for such defaults (or
               rights of termination, cancellation or acceleration) as to which
               requisite waivers or consents have been obtained or that would
               not, individually or in the aggregate, create a material adverse
               effect on DLC; or (iii) constitute violations of any law,
               regulation,

               corporation authorized to transact business and to own and lease
               property in each jurisdiction in which the nature of the business
               conducted by it or the character or location of the properties
               owned or leased by it requires such qualification. DLC is not in
               violation of any term of its certificate of incorporation or
               by-laws, as amended through and including the Effective Date, or
               any agreement, instrument, judgment, decree, order, statute, rule
               or governmental regulation applicable to it, which would have a
               Material Adverse Effect on Orion Midwest.

               hereunder and the consummation of the transactions contemplated
               hereby have been duly authorized by all necessary corporate
               action of DLC. This Agreement has been duly executed and
               delivered by DLC and constitutes a valid and binding obligation
               of DLC, enforceable against it in accordance with its terms,
               except that the enforcement hereof and thereof may be limited by

               similar laws now or hereafter in effect relating to creditors
               rights generally and general principles of equity (regardless of
               whether enforceability is considered in a proceeding at law or in
               equity).

               death of persons or for loss or claims for loss of or damage to

     9.3 Co-operation Regarding Claims. If any Party (in such capacity an
         -----------------------------
"Indemnified Party") receives notice or has knowledge of any Loss that may
 -----------------
result in a claim for indemnification by such Indemnified Party against the
other Party (in such capacity, an "Indemnifying Party") pursuant to this Article
                                   ------------------
IX, such Indemnified Party shall as promptly as possible give the Indemnifying
Party notice of such Loss, including a reasonably detailed description of the
facts and circumstances relating to such Loss, and a complete copy of all
notices, pleadings and other papers related thereto, and in reasonable detail
the basis for its potential claim for indemnification with respect thereto;
provided, that failure promptly to give such notice or to provide such
information and documents shall not relieve the Indemnifying Party from the
obligation hereunder to respond to or to defend the Indemnified Party against
such Loss unless such failure shall materially diminish the ability of the
Indemnifying Party to respond to such claim or to defend the Indemnified Party.
The Indemnifying Party, upon its acknowledgment in writing of its obligation to
indemnify the Indemnified Party, shall be entitled to assume the defense or to
represent the interests of the Indemnified Party seeking indemnification in
respect of such Loss, which shall include the right to select and direct legal
counsel and other consultants as acceptable to the other Party, appear in
proceedings on behalf of such Indemnified Party and to propose, accept or reject
offers of settlement, all at its sole cost; provided, that no such settlement
shall be made without the consent of the Indemnified Party (which consent shall
not be unreasonably withheld); provided, further, that if any such settlement is
reasonably likely to involve injunctive, equitable or prospective relief or
materially and adversely to affect the Indemnified Party's business or
operations other than as a result of money damages or other money payments, then
the Indemnified Party shall be entitled to take control of the defense and
investigation of such Loss, to employ and engage legal counsel and other
consultants of its own choice to handle and defend the same, and to compromise
or settle such claim, all at the Indemnifying Party's cost, risk and expense;
and provided, further that if the Loss is settled without the Indemnifying
Party's consent (which consent shall not be unreasonably withheld), the
Indemnified Party shall be deemed to have waived all rights hereunder against
the Indemnifying Party for damages arising out of such Loss. Nothing herein
shall prevent an Indemnified Party from retaining its own legal counsel and
other consultants and participating in its own defense at its own cost and
expense. The Parties shall cooperate with each other in any notifications to
insurers.

          ---------------------------
          means those causes beyond the reasonable control of the Party

          Good Utility Practice, such Party is unable to prevent, avoid,
          mitigate or overcome, including the following: any act of God, labor
          dispute (including a strike), act of the public enemy, war, civil
          disturbance, insurrection, riot, fire, storm or flood, lightning,
          explosion, order, government decree or rule, regulation or restriction

     10.2 Limitation of Liability. Notwithstanding anything in this Agreement to
          -----------------------
          the contrary, neither DLC nor Orion Midwest shall be liable in
          damages, or otherwise responsible to each other, for its failure to
          perform or observe any of its obligations under this Agreement, if and
          only to the extent that it is unable to perform or is prevented from
          performing by an event of Force Majeure during its continuance,
          provided that the Party affected by such event has taken all
          reasonable precautions and exercised due care to avoid the effect of
          such event on such Party's ability to perform or observe its
          obligations under this Agreement.

     10.3 Force Majeure Procedures. Upon the occurrence of an event of Force
          ------------------------
          Majeure, the Party affected by such event shall: (a) provide prompt
          written notice of such Force Majeure event to the other Party,
          including an estimation of its expected duration and the probable
          impact on the performance of its obligations hereunder; (b) exercise
          all reasonably efforts in accordance with Good Utility Practice to
          continue to perform its obligations under this Agreement; (c)
          expeditiously take action to correct or cure the event or condition
          excusing performance, provided, however, that settlement of labor
          disputes will be completely within the sole discretion of the Party
          affected by such labor dispute; (d) exercise all reasonable efforts to
          mitigate or limit damages to the other Party; and (e) provide prompt
          notice to the other Party of the cessation of the event or condition
          giving rise to its excuse from performance. Any obligation under this
          Agreement shall be suspended only to the extent caused by such Force
          Majeure event and only during the continuance of any inability of
          performance caused by such Force Majeure event but for no longer
          period.
