     5.1  Funding of Working Capital and Capital Contributions.

     (a)  The Office of the Interconnection shall attempt to obtain financing of
up to twenty-five percent (25%) of the approved annual operating budget of the
LLC adopted by the PJM Board pursuant to Section 7.5.2 of this Agreement to meet
the working capital needs of the LLC, which shall be limited to such working
capital needs that arise from timing in cash flows from interchange accounting,
tariff administration and payment of the operating costs of the Office of the
Interconnection.  Such financing, which shall be non-recourse to the Members of
the LLC and which shall be for a stated term without penalty for prepayment, may
be obtained by borrowing the amount required at market-based interest rates,
negotiated on an arm's length basis, (i) from a Member or Members or (ii) from a
commercial lender, supported, if necessary, by credit enhancements provided by a
Member or Members; provided, however, no Member shall be obligated to provide
such financing or credit enhancements.  The LLC shall make such filings and seek
such approvals as necessary in order for the principal, interest and fees
related to any such borrowing to be repaid through charges under the PJM Tariff
as appropriate under Schedule 3 of this Agreement.

written notice as provided in Section 18.18.2 of this Agreement.

the approved annual operating budget of the LLC, for working capital or
otherwise, as the PJM Board deems appropriate to fund the operations of the LLC,
in accordance with the general powers of the LLC under Section 3.2 to enter into
obligations of any kind to accomplish the purposes of the LLC.  Nor shall
anything in Section 5.1(a) and (b) in any way restrict the authority of the PJM
Board to authorize the LLC to grant to lenders such security interests or other
rights in assets or revenues received under the PJM Tariff with respect to the
costs of operating the LLC and the Office of the Interconnection and to take
such other actions as it deems necessary and appropriate to obtain such
financing in accordance with such general powers of the LLC under Section 3.2.

     5.2  Contributions to Association.

     All contributions prior to the Effective Date of the original Operating
Agreement of PJM Interconnection, L.L.C. of cash or other assets to the PJM
Interconnection Association by persons who are now or in the future may become
Members of the LLC shall be deemed contributions by such Members to the LLC.

     6.1  Tax Status.

     The LLC shall make all necessary filings under the applicable Treasury
Regulations to have the LLC taxed as a corporation.

accordance with Section 5.1 herein, the LLC shall request the Transmission
Owners to recover such working capital through charges under the PJM Tariff as
provided in Schedule 3 of this Agreement.  In the event all or a portion of the
working capital is recovered pursuant to the PJM Tariff, such amount(s) shall be
returned to the Members in accordance with their actual contributions.

               15.1.3    Payment of Bills.

               (a)       A Member shall make full and timely payment, in
accordance with the terms specified by the Office of the Interconnection, of all
bills rendered in connection with or arising under or from this Agreement, any
service or rate schedule, any tariff, or any services performed by the Office of
the Interconnection, notwithstanding any disputed amount, but any such payment
shall not be deemed a waiver of any right with respect to such dispute. With
respect to any payment that the LLC is required to make to a Member in
connection with or arising under this Agreement, any service or rate schedule,
or any tariff, the LLC shall have a right of setoff equal to any amount that the
Member is required to pay the LLC in connection with or arising under or from
this Agreement, any service or rate schedule, any tariff, or any services
performed by the Office of the Interconnection. Any Member that fails to make
full and timely payment to the LLC, or otherwise fails to meet its financial or
other obligations to a Member, the Office of the Interconnection or the LLC
under this Agreement, shall upon expiration of the 10 day period specified below
be in default. If the Office of the Interconnection concludes, upon its own
initiative or the recommendation of or complaint by the Members Committee or any
Member, that a Member is in breach of any obligation under this Agreement, the
Office of the Interconnection shall so notify such Member and inform all other
Members. The notified Member may remedy such asserted breach by: (i) paying all
amounts assertedly due, along with interest on such amounts calculated in
accordance with the methodology specified for interest on refunds in FERC's
regulations at 18 C.F.R. (S) 35.19a(a)(2)(iii); and (ii) demonstration to the
satisfaction of the Office of the Interconnection that the Member has taken
appropriate measures to meet any other obligation of which it was deemed to be
in breach; provided, however, that any such payment or demonstration may be
subject to a reservation of rights, if any, to subject such matter to the PJM
Dispute Resolution Procedures; and provided, further, that any such
determination by the Office of the Interconnection may be subject to review by
the PJM Board upon request of the Member involved or the Office of the
Interconnection. If a Member has not remedied a breach by the 10th business day
following receipt of the Office of the Interconnection's notice, or receipt of
the PJM Board's decision on review, if applicable, then the Member shall be in
default and, in addition to such other remedies as may be available to the LLC:

               i)        A defaulting Market Participant shall be precluded from
                         buying or selling energy in the PJM Interchange Energy
                         Market until the default is remedied as set forth
                         above;

               ii)       A defaulting Member shall not be entitled to
                         participate in the activities of any committee or other
                         body established by the Members Committee or the Office
                         of the Interconnection; and

               iii)      A defaulting Member shall not be entitled to vote on
                         the Members Committee or any other committee or other
                         body established pursuant to this Agreement.

     15.2      Enforcement of Obligations.

     If the Office of the Interconnection sends a notice to the PJM Board that a
Member has failed to perform an obligation under this Agreement, the PJM Board
shall initiate such action against such Member to enforce such obligation as the
PJM Board shall deem appropriate.  Subject to the procedures specified in
Section 15.1, a Member's failure to perform such obligation shall be deemed to
be a default under this Agreement.  In order to remedy a default, but without
limiting any rights the LLC may have against the defaulting Member, the PJM
Board may assess against, and collect from, the Members not in default, in
proportion to their Weighted Interest, an amount equal to the amount that the
defaulting Member has failed to pay to the Office of the Interconnection, along
with appropriate interest, but such assessment shall in no way relieve the
defaulting Member of its obligations, and shall confer upon the Members
Committee the right to recover the assessed amounts from the defaulting Member.
In addition to any amounts in default, the defaulting Member shall be liable to
the LLC for reasonable costs incurred in enforcing the defaulting Member's
obligations.

     15.3      Obligations to a Member in Default.

     The Members have no continuing obligation to provide the benefits of
interconnected operations to a Member in default.

     15.4      Obligations of a Member in Default.

     A Member found to be in default shall take all possible measures to
mitigate the continued impact of the default on the Members not in default,
including, but not limited to, loading its own generation to supply its own load
to the maximum extent possible.

     15.5      No Implied Waiver.

     A failure of a Member, the PJM Board, or the LLC to insist upon or enforce
strict performance of any of the provisions of this Agreement shall not be
construed as a waiver or relinquishment to any extent of such entity's right to
assert or rely upon any such provisions, rights and remedies in that or any
other instance; rather, the same shall be and remain in full force and effect.

     16.1      Members.

     (a)       As between the Members, except as may be otherwise agreed upon
between individual Members with respect to specified interconnections, each
Member will indemnify and hold harmless each of the other Members, and its
directors, officers, employees, agents, or representatives, of and from any and
all damages, losses, claims, demands, suits, recoveries, costs and expenses
(including all court costs and reasonable attorneys' fees), caused by reason of
bodily injury, death or damage to property of any third party, resulting from or
attributable to the fault, negligence or willful misconduct of such Member, its
directors, officers, employees, agents, or representatives, or resulting from,
arising out of, or in any way connected with the performance of its obligations
under this Agreement, excepting only, and to the extent, such cost, expense,
damage, liability or loss may be caused by the fault, negligence or willful
misconduct of any other Member. The duty to indemnify under this Agreement will
continue in full force and effect notwithstanding the expiration or termination
of this Agreement or the withdrawal of a Member from this Agreement, with
respect to any loss, liability, damage or other expense based on facts or
conditions which occurred prior to such termination or withdrawal.

     (b)       The amount of any indemnity payment arising hereunder shall be
reduced (including, without limitation, retroactively) by any insurance proceeds
or other amounts actually recovered by the Member seeking indemnification in
respect of the indemnified action, claim, demand, costs, damage or liability. If
any Member shall have received an indemnity payment for an action, claim,
demand, cost, damage or liability and shall subsequently actually receive
insurance proceeds or other amounts for such action, claim, demand, cost, damage
or liability, then such Member shall pay to the Member that made such indemnity
payment the lesser of the amount of such insurance proceeds or other amounts
actually received and retained or the net amount of the indemnity payments
actually received previously.

officers, employees and agents, and any representatives of the Members serving
on the Members Committee and any other committee created under Section 8 of this
Agreement (all such Board Members, officers, employees, agents and
representatives for purposes of this Section 16 being referred to as "LLC
Indemnified Parties"), of and from any and all actions, claims, demands, costs
(including consequential or indirect damages, economic losses and all court
costs and reasonable attorneys' fees) and liabilities to any third parties,
arising from, or in any way connected with, the performance of the LLC under
this Agreement, or the fact that such LLC Indemnified Party was serving in such
capacity, except to the extent that such action, claim, demand, cost or
liability results from the willful misconduct of any LLC Indemnified Party with
respect to participation in the misconduct. To the extent any dispute arises
between any Member and the LLC arising from, or in any way connected with, the
performance of the LLC under this Agreement, the Member and the LLC shall follow
the PJM Dispute Resolution Procedures. To the extent that any such action,
claim, demand, cost or liability arises from a Member's contractual or other
obligation to provide electric service directly or indirectly to said third
party, which obligation to provide service is limited by the terms of any
tariff, service agreement, franchise, statute, regulatory requirement, court
decision or other limiting provision, the Member designates the LLC and each LLC
Indemnified Party a beneficiary of said limitation.

     (b)       An LLC Indemnified Party shall not be personally liable for
monetary damages for any breach of fiduciary duty by such LLC Indemnified Party,
except that an LLC Indemnified Party shall be liable to the extent provided by
applicable law (i) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law, or (ii) for any
transaction from which the LLC Indemnified Party derived an improper personal
benefit. Notwithstanding (i) and (ii), indemnification shall be made in respect
of any claim, issue or matter as to which such person shall have been adjudged
to be liable to the LLC if and to the extent that the court in which such action
or suit was brought shall determine upon application that, despite the
adjudication of liability but in view of all the circumstances of the case, such
person is fairly and reasonably entitled to indemnity for such expenses which
such court shall deem proper. If applicable law is hereafter construed or
amended to authorize the further elimination or limitation of the liability of
LLC Indemnified Parties, then the liability of the LLC Indemnified Parties, in
addition to the limitation on personal liability provided herein, shall be
limited to the fullest extent permitted by law. No amendment to or repeal of
this section shall apply to or have any effect on the liability or alleged
liability of any LLC Indemnified Party or with respect to any acts or omissions
occurring prior to such amendment or repeal. The termination of any action, suit
or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo
contendere or its equivalent, shall not, of itself, create a presumption that
the person did not act in good faith and in a manner which such person
reasonably believed to be in or not opposed to the best interests of the LLC,
and with respect to any criminal action or proceeding, had reasonable cause to
believe that his or her conduct was unlawful.

     (c)       The LLC may pay expenses incurred by an LLC Indemnified Party in
defending a civil, criminal, administrative or investigative action, suit or
proceeding in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of such LLC
Indemnified Party to repay such amount if it shall ultimately be determined that
such LLC Indemnified Party is not entitled to be indemnified by the LLC as
authorized in this Section.

counsel to the LLC. If the PJM Board concludes that either or both of Sections

provisions of this Agreement shall continue in full force and effect and shall

or provisions which otherwise give effect to the original intent of the invalid,

far as reasonably practicable and to remedy the event, provided that no Member
shall be required by this provision to settle any strike or labor dispute.

     18.17  Confidentiality.

            18.17.1  Party Access.

            (a)   No Member shall have a right hereunder to receive or review
any documents, data or other information of another Member, including documents,
data or other information provided to the Office of the Interconnection, to the
extent such documents, data or information have been designated as confidential
pursuant to the procedures adopted by the Office of the Interconnection or to
the extent that they have been designated as confidential by such other Member;
provided, however, a Member may receive and review any composite documents, data
and other information that may be developed based on such confidential
documents, data or information if the composite does not disclose any individual
Member's confidential data or information.

            (b)   Except as may be provided in this Agreement or in the PJM Open
Access Transmission Tariff, the Office of the Interconnection shall not disclose
to its Members or to third parties, any documents, data, or other information of
a Member or entity applying for Membership, to the extent such documents, data,
or other information has been designated confidential pursuant to the procedures
adopted by the Office of the Interconnection or by such Member or entity
applying for membership; provided that nothing contained herein shall prohibit
the Office of the Interconnection from providing any such confidential
information to its agents, representatives, or contractors to the extent that
such person or entity is bound by an obligation to maintain such
confidentiality. The Office of the Interconnection shall collect and use
confidential information only in connection with its authority under this
Agreement and the Open Access Transmission Tariff and the retention of such
information shall be in accordance with PJM's data retention policies.

third party provided that the Member has delivered to the Office of the
Interconnection specific, written authorization for such release setting forth

the period of time for which such release shall be authorized. The Office of the
Interconnection shall limit the release of a Member's confidential data or
information to that specific authorization received from the Member. Nothing
herein shall prohibit a Member from withdrawing such authorization upon written
notice to the Office of the Interconnection who shall cease such release as soon

           18.17.2  Required Disclosure.

           (a)      Notwithstanding anything in the foregoing Section to the
contrary, and subject to the provisions of Section 18.17.3, if a Member or the
Office of the Interconnection is required by applicable law, or in the course of
administrative or judicial proceedings other than FERC proceedings or
investigations, to disclose to third parties other than the FERC or its staff,
information that is otherwise required to be maintained in confidence pursuant
to this Agreement, that Member or the Office of the Interconnection may make
disclosure of such information; provided, however, that as soon as the Member or
the Office of the Interconnection learns of the disclosure requirement and prior
to making disclosure, that Member or the Office of the Interconnection shall
notify the affected Member or Members of the requirement and the terms thereof
and the affected Member or Members may direct, at their sole discretion and
cost, any challenge to or defense against the disclosure requirement. The
disclosing Member and the Office of the Interconnection shall cooperate with
such affected Members to the maximum extent practicable to minimize the
disclosure of the information consistent with applicable law. Each Member and
the Office of the Interconnection shall cooperate with the affected Members to
obtain proprietary or confidential treatment of such information by the person
to whom such information is disclosed prior to any such disclosure.

           (b)      Nothing in this Section 18.17 shall prohibit or otherwise
limit the Office of the Interconnection's use of information covered herein if
such information was: (i) previously known to the Office of the Interconnection
without an obligation of confidentiality; (ii) independently developed by or for
the Office of the Interconnection using nonconfidential information; (iii)
acquired by the Office of the Interconnection from a third party which is not,
to the Office of the Interconnection's knowledge, under an obligation of
confidence with respect to such information; (iv) which is or becomes publicly
available other than through a manner inconsistent with this Section 18.17. (c)
The Office of the Interconnection shall impose on any contractors retained to
provide technical support or otherwise to assist with the implementation or
administration of this Agreement or of the Open Access Transmission Tariff a
contractual duty of confidentiality consistent with this Agreement. A Member
shall not be obligated to provide confidential or proprietary information to any
contractor that does not assume such a duty of confidentiality, and the Office
of the Interconnection shall not provide any such information to any such
contractor without the express written permission of the Member providing the
information.

           (d)      Section 18.17.2(a) does not apply to disclosure of
information to the FERC or its staff.

resource shall receive payments or credits for energy or related services, or
for start-up and no-load fees, from the Office of the Interconnection on behalf
of the Market Buyers in accordance with Section 3 of this Schedule 1.
Alternatively, the Market Seller shall receive, in lieu of start-up and no-load
fees, its actual costs incurred, if any, up to a cap of the resource's start-up
cost, if the Office of the Interconnection cancels its selection of the resource
as a pool-scheduled resource and so notifies the Market Seller before the
resource is synchronized.

          (e)    Market Participants shall make available their pool-scheduled
resources to the Office of the Interconnection for coordinated operation to
supply the needs of the PJM Control Area for Operating Reserves.

          1.10.3 Self-scheduled Resources.

          Self-scheduled resources shall be governed by the following principles
and procedures.

          (a)    Each Generating Market Buyer shall use all reasonable efforts,
consistent with Good Utility Practice, not to self-schedule resources in excess
of its Equivalent Load.

          (b)    The offered prices of resources that are self-scheduled, or
otherwise not following the dispatch orders of the Office of the
Interconnection, shall not be considered by the Office of the Interconnection in
determining Locational Marginal Prices.

          (c)    Market Participants shall make available their self-scheduled
resources to the Office of the Interconnection for coordinated operation to
supply the needs of the PJM Control Area for Operating Reserves.

          1.10.8 Office of the Interconnection Responsibilities.

          (a)    The Office of the Interconnection shall use its best efforts to
determine (i) the least-cost means of satisfying the projected hourly
requirements for energy, Operating Reserves, and other ancillary services of the
Market Buyers, including the reliability requirements of the PJM Control Area,
of the Day-ahead Energy Market, and (ii) the least-cost means of satisfying the
Operating Reserve and other ancillary service requirements for any portion of
the load forecast of the Office of the Interconnection for the Operating Day in
excess of that scheduled in the Day-ahead Energy Market.  In making these
determinations, the Office of the Interconnection shall take into account:  (i)
the Office of the Interconnection's forecasts of PJM Interchange Energy Market
and PJM Control Area energy requirements, giving due consideration to the energy
requirement forecasts and purchase requests submitted by Market Buyers; (ii) the
offers submitted by Market Sellers; (iii) the availability of limited energy
resources; (iv) the capacity, location, and other relevant characteristics of
self-scheduled resources; (v) the objectives of the PJM Control Area for
Operating Reserves, as specified in the PJM Manuals; (vi) the requirements of
the PJM Control Area for Regulation and other ancillary services, as specified
in the PJM Manuals; (vii) the benefits of avoiding or minimizing transmission
constraint control operations, as specified in the PJM Manuals; and (viii) such
other factors as the Office of the Interconnection reasonably concludes are
relevant to the foregoing determination.  The Office of the Interconnection
shall develop a Day-ahead Energy Market based on the foregoing determination,
and shall determine the Day-ahead Prices resulting from such schedule.  The
Office of the Interconnection shall report the planned schedule for a hydropower
resource to the operator of that resource as necessary for plant safety and
security, and legal limitations on pond elevations.

          (b)    Not later than 4:00 p.m. of the day before each Operating Day,
or such earlier deadline as may be specified by the Office of the
Interconnection in the PJM Manuals, the Office of the Interconnection shall: (i)
post the aggregate Day-ahead Energy Market; (ii) post the Day-ahead Prices; and
(iii) inform the Market Sellers and Market Buyers of their scheduled injections
and withdrawals respectively.

          (c)    Following posting of the information specified in Section
1.10.8(b), the Office of the Interconnection shall revise its schedule of
generation resources to reflect updated projections of load, conditions
affecting electric system operations in the PJM Control Area, the availability
of and constraints on limited energy and other resources, transmission
constraints, and other relevant factors. The Office of the Interconnection shall
post on the PJM Open Access Same-time Information System at times specified in
the PJM Manuals a revised forecast of the location and duration of any expected
transmission congestion, and of the range of differences in Locational Marginal
Prices between major subareas of the PJM Control Area expected to result from
such transmission congestion.

Interconnection of the Locational Marginal Prices resulting from the Day-ahead
Energy Market, and subject to the right of the Office of the Interconnection to
schedule and dispatch pool-scheduled resources and to direct that schedules be
changed in an Emergency, a generation rebidding period shall exist from 4:00
p.m. to 6:00 p.m. on the day before each Operating Day. During the rebidding
period, Market Participants may submit revisions to generation offer data for
any generation resource that was not selected as a pool-scheduled resource in
the Day-ahead Energy Market. Adjustments to Day-ahead Energy Markets shall be
settled at the applicable Real-time Prices, and shall not affect the obligation
to pay or receive payment for the quantities of energy scheduled in the Day-
ahead Energy market at the applicable Day-ahead Prices.

          (b)    A Market Participant may adjust the schedule of a resource
under its dispatch control on an hour-to-hour basis beginning at 10:00 p.m. of
the day before each Operating Day, provided that the Office of the
Interconnection is notified not later than 60 minutes prior to the hour in which
the adjustment is to take effect, as follows:

          i)     A Generating Market Buyer may self-schedule any of its resource
                 increments, including hydropower resources, not previously
                 designated as self-scheduled and not selected as a pool-
                 scheduled resource in the Day-ahead Energy Market;

          ii)    A Market Participant may request the scheduling of a non-firm
                 bilateral transaction; or

          iii)   A Market Participant may request the scheduling of deliveries
                 or receipts of Spot Market Energy; or

          iv)    A Generating Market Buyer may remove from service a resource
                 increment, including a hydropower resource, that it had
                 previously designated as self-scheduled, provided that the
                 Office of the Interconnection shall have the option to schedule
                 energy from any such resource increment that is a Capacity
                 Resource at the price offered in the scheduling process, with
                 no obligation to pay any start-up fee.

          (c)    With respect to a pool-scheduled resource that is included in
the Day-ahead Energy Market, a Market Seller may not change or otherwise modify
its offer to sell energy.

          (d) An External Market Buyer may refuse delivery of some or all of the
energy it requested to purchase in the Day-ahead Energy Market by notifying the
Office of the Interconnection of the adjustment in deliveries not later than 60
minutes prior to the hour in which the adjustment is to take effect, but any
such adjustment shall not affect the obligation of the External Market Buyer to
pay for energy scheduled on its behalf in the Day-ahead Energy Market at the
applicable Day-ahead Prices.

          (a)    The Office of the Interconnection shall implement the dispatch
of energy from pool-scheduled resources with limited energy by direct request.
In implementing mandatory or economic use of limited energy resources, the
Office of the Interconnection shall use its best efforts to select the most
economic hours of operation for limited energy resources, in order to make
optimal use of such resources consistent with the dynamic load-following
requirements of the PJM Control Area and the availability of other resources to
the Office of the Interconnection.

          (b)    The Office of the Interconnection shall implement the dispatch
of energy from other pool-dispatched resource increments, including generation
increments from Capacity Resources the remaining increments of which are self-
scheduled, by sending appropriate signals and instructions to the entity
controlling such resources, in accordance with the PJM Manuals. Each Market
Seller shall ensure that the entity controlling a pool-dispatched resource
offered or made available by that Market Seller complies with the energy
dispatch signals and instructions transmitted by the Office of the
Interconnection.

                 1.11.3A  Maximum Generation Emergency.

          If the Office of the Interconnection declares a Maximum Generation
Emergency, all deliveries to load that is served by Point-to-Point Transmission
Service outside the PJM Control Area from Capacity Resources may be interrupted
in order to serve load in the PJM Control Area.

          1.11.4 Regulation

          (a)    A Market Buyer may satisfy its Regulation obligation from its
own resources capable of performing Regulation service, by contractual
arrangements with other Market Participants able to provide Regulation service,
or by purchases from the PJM Interchange Energy Market at the rates set forth in
Section 3.2.2.

          (b)    The Office of the Interconnection shall obtain Regulation
service from the least-cost alternatives available from either pool-scheduled or
self-scheduled resources as needed to meet PJM Control Area requirements not
otherwise satisfied by the Market Buyers. Resources offering to sell Regulation
shall be selected to provide Regulation on the basis of each resource's
regulation offer and the estimated opportunity cost of the resource providing
regulation and in accordance with the Office of the Interconnection's obligation
to minimize the total cost of energy, Operating Reserves, Regulation, and other
ancillary services. Estimated opportunity costs shall be determined by the
Office of the Interconnection on the basis of the expected value of the energy
sales that would be foregone or uneconomic energy that would be produced by the
resource in order to provide Regulation, in accordance with procedures specified
in the PJM Manuals. If the Office of the Interconnection is not able to
distinguish resources offering Regulation on the basis of their regulation
offers and estimated opportunity costs, resources shall be selected on the basis
of the quality of Regulation provided by the resource as determined by tests
administered by the Office of the Interconnection.

          (c)    The Office of the Interconnection shall dispatch resources for
Regulation by sending Regulation signals and instructions to resources from
which Regulation service has been offered by Market Sellers, in accordance with
the PJM Manuals. Market Sellers shall comply with Regulation dispatch signals
and instructions transmitted by the Office of the Interconnection and, in the
event of conflict, Regulation dispatch signals and instructions shall take
precedence over energy dispatch signals and instructions. Market Sellers shall
exert all reasonable efforts to operate, or ensure the operation of, their
resources supplying load in the PJM Control Area as close to desired output
levels as practical, consistent with Good Utility Practice.

          1.11.5 PJM Open Access Same-time Information System.

          The Office of the Interconnection shall update the information posted
on the PJM Open Access Same-time Information System to reflect its dispatch of

     1.12 Dynamic Scheduling.

     (a)  An entity that owns or controls a generating resource in the PJM
Control Area may electrically remove all or part of the generating resource's
output from the PJM Control Area through dynamic scheduling of the output to
load outside the PJM Control Area.  Such output shall not be available for
economic dispatch by the Office of the Interconnection.

     (b)  An entity requesting dynamic scheduling shall be responsible for
arranging for the provision of signal processing and communications from the
generator to the Office of the Interconnection and the other participating
control area and complying with any other procedures established by the Office
of the Interconnection regarding dynamic scheduling as set forth in the PJM
Manuals.

     (c)  An entity requesting dynamic scheduling shall be responsible for
reserving amounts of firm transmission service necessary to deliver the range of
the dynamic transfer and any required ancillary services.

           2.   CALCULATION OF LOCATIONAL MARGINAL PRICES

     2.1  Introduction.

     The Office of the Interconnection shall calculate the price of energy at
the load busses and generation busses in the PJM Control Area and at the
interface busses between the PJM Control Area and adjacent Control Areas on the
basis of Locational Marginal Prices.  Locational Marginal Prices determined in
accordance with this Section shall be calculated on a day-ahead basis for each
hour of the Day-ahead Energy Market, and every five minutes during the Operating
Day for the Real-time Energy Market.

     2.2  General.

     The Office of the Interconnection shall determine the least cost security-
constrained dispatch, which is the least costly means of serving load at
different locations in the PJM Control Area based on actual operating conditions
existing on the power grid and on the prices at which Market Sellers have
offered to supply energy in the PJM Interchange Energy Market.  Locational
Marginal Prices for the generation and load busses in the PJM Control Area,
including interconnections with other Control Areas, will be calculated based on
the actual economic dispatch and the prices of energy offers.  The process for
the determination of Locational Marginal Prices shall be as follows:

     (a)  To determine actual operating conditions on the power grid in the PJM
Control Area, the Office of the Interconnection shall use a computer model of
the interconnected grid that uses available metered inputs regarding generator
output, loads, and power flows to model remaining flows and conditions,
producing a consistent representation of power flows on the network.  The
computer model employed for this purpose, referred to as the State Estimator
program, is a standard industry tool and is described in Section 2.3 below.  It
will be used to obtain information regarding the output of generation supplying
energy to the PJM Control Area, loads at buses in the PJM Control Area,
transmission losses, and power flows on binding transmission constraints for use
in the calculation of Locational Marginal Prices.  Additional information used
in the calculation, including Dispatch Rates and real time schedules for
external transactions between PJM and other Control Areas, will be obtained from
the Office of the Interconnection's dispatchers.

     (b)  Using the prices at which energy is offered by Market Sellers to the
PJM Interchange Energy Market, the Office of the Interconnection shall determine
the offers of energy that will be considered in the calculation of Locational
Marginal Prices.  As described in Section 2.4 below, every offer of energy by a
Market Seller from a resource that is following economic dispatch instructions
of the Office of the Interconnection will be utilized in the calculation of
Locational Marginal Prices.

     (c)  Based on the system conditions on the PJM power grid, determined as
described in (a), and the eligible energy offers, determined as described in
(b), the Office of the Interconnection shall determine the least costly means of
obtaining energy to serve the next increment of load at each bus in the PJM
Control Area, in the manner described in Section 2.5 below.   The result of that
calculation shall be a set of Locational Marginal Prices based on the system
conditions at the time.

     2.3  Determination of System Conditions Using the State Estimator.

     Power system operations, including, but not limited to, the determination
of the least costly means of serving load, depend upon the availability of a
complete and consistent representation of generator outputs, loads, and power
flows on the network.  In calculating Locational Marginal Prices, the Office of
the Interconnection shall obtain a complete and consistent description of
conditions on the electric network in the PJM Control Area by using the most
recent power flow solution produced by the State Estimator, which is also used
by the Office of the Interconnection for other functions within power system
operations.  The State Estimator is a standard industry tool that produces a
power flow model based on available real-time metering information, information
regarding the current status of lines, generators, transformers, and other
equipment, bus load distribution factors, and a representation of the electric
network, to provide a complete description of system conditions, including
conditions at busses for which real-time information is unavailable.   The
current version of the State Estimator includes over 1600 busses in the PJM
Control Area, as well as interface busses with adjacent Control Areas.  The
Office of the Interconnection shall obtain a State Estimator solution every five
minutes, which shall provide the megawatt output of generators and the loads at
busses in the PJM Control Area, transmission line losses, and actual flows or
loadings on constrained transmission facilities.  External transactions between
PJM and other Control Areas shall be included in the Locational Marginal Price
calculation on the basis of the real time transaction schedules implemented by
the Office of the Interconnection's dispatcher.

     2.4  Determination of Energy Offers Used in Calculating Real-time Prices.

     (a)  During the Operating Day, real-time Locational Marginal Prices derived
in accordance with this Section shall be determined every five minutes and
integrated hourly values of such determinations shall be the basis of sales and
purchases of energy in the Real-time Energy Market and of Transmission
Congestion Charges under the PJM Tariff not covered by the Day-ahead Energy
Market.

     (b)  To determine the energy offers submitted to the PJM Interchange Energy
Market that shall be used during the Operating Day to calculate the Real-time
Prices, the Office of the Interconnection shall determine which resources are
following its economic dispatch instructions.  A resource will be considered to
be following economic dispatch instructions and shall be included in the
calculation of Real-time Prices if:

          i)     the applicable price bid by a Market Seller for energy from the
                 resource is less than or equal to the Dispatch Rate for the
                 area of the PJM Control Area in which the resource is located;
                 or

          ii)    the resource is specifically requested to operate by the Office
                 of the Interconnection's dispatcher.

     (c)  In determining whether a resource satisfies the condition described in
(b), the Office of the Interconnection will determine the bid price associated
with an energy offer by comparing the actual megawatt output of the resource
with the Market Seller's offer price curve.  Because of practical generator
response limitations, a resource whose megawatt output is not ten percent more
than the megawatt level specified on the offer price curve for the applicable
Dispatch Rate shall be deemed to be following economic dispatch instructions,
but the energy price offer used in the calculation of Real-time Prices shall not
exceed the applicable Dispatch Rate.  Units that must be run for local area
protection shall not be considered in the calculation of Real-time Prices.

     2.5  Calculation of Real-time Prices.

     (a)  The Office of the Interconnection shall determine the least costly
means of obtaining energy to serve the next increment of load at each bus in the
PJM Control Area represented in the State Estimator and each interface bus
between the PJM Control Area and an adjacent Control Area, based on the system
conditions described by the most recent power flow solution produced by the
State Estimator program and the energy offers that are the basis for the Day-
ahead Energy Market, or that are determined to be eligible for consideration
under Section 2.4 in connection with the real-time dispatch, as applicable.
This calculation shall be made by applying an incremental linear optimization
method to minimize energy costs, given actual system conditions, a set of energy
offers, and any binding transmission constraints that may exist.  In performing
this calculation, the Office of the Interconnection shall calculate the cost of
serving an increment of load at each bus from each resource associated with an
eligible energy offer as the sum of:  (1) the price at which the Market Seller
has offered to supply an additional increment of energy from the resource, and
(2) the effect on transmission congestion costs (whether positive or negative)
associated with increasing the output of the resource, based on the effect of
increased generation from that resource on transmission line loadings.  The
energy offer or offers that can serve an increment of load at a bus at the
lowest cost, calculated in this manner, shall determine the Real-time Price at
that bus.

     (b)  During the Operating Day, the calculation set forth in (a) shall be
performed every five minutes, using the Office of the Interconnection's
Locational Marginal Price program, producing a set of Real-time Prices based on
system conditions during the preceding interval.  The prices produced at five-
minute intervals during an hour will be integrated to determine the Real-time
Prices for that hour.

     2.6  Calculation of Day-ahead Prices.

     For the Day-ahead Energy Market, day-ahead Locational Marginal Prices shall
be determined on the basis of the least-cost, security-constrained dispatch,
model flows and system conditions resulting from the load specifications, offers
for generation, dispatchable load, Increment Bids, Decrement Bids, and bilateral
transactions submitted to the Office of the Interconnection and scheduled in the
Day-ahead Energy Market.  Such prices shall be determined in accordance with the
provisions of this Section applicable to the Day-ahead Energy Market and shall
be the basis for purchases and sales of energy and Transmission Congestion
Charges resulting from the Day-ahead Energy Market.  This calculation shall be
made for each hour in the Day-ahead Energy Market by applying a linear
optimization method to minimize energy costs, given scheduled system conditions,
scheduled transmission outages, and any transmission limitations that may exist.
In performing this calculation, the Office of the Interconnection shall
calculate the cost of serving an increment of load at each bus from each
resource associated with an eligible energy offer as the sum of: (1) the price
at which the Market Seller has offered to supply an additional increment of
energy from the resource, and (2) the effect on transmission congestion costs
(whether positive or negative) associated with increasing the output of the
resource, based on the effect of increased generation from that resource on
transmission line loadings.  The energy offer or offers that can serve an
increment of load at a bus at the lowest cost, calculated in this manner, shall
determine the Day-ahead Price at that bus.

     2.7  Performance Evaluation.

     The Office of the Interconnection shall undertake an evaluation of the
foregoing procedures for the determination of Locational Marginal Prices, as
well as the procedures for determining and allocating Fixed Transmission Rights
and associated Transmission Congestion Charges and Credits, not less often than
every two years, in accordance with the PJM Manuals.  To the extent practical,
the Office of the Interconnection shall retain all data needed to perform
comparisons and other analyses of locational marginal pricing.  The Office of
the Interconnection shall report the results of its evaluation to the Market
Participants, along with its recommendations, if any, for changes in the
procedures.

                          3.   ACCOUNTING AND BILLING

     3.1  Introduction.

     This schedule sets forth the accounting and billing principles and
procedures for the purchase and sale of services on the PJM Interchange Energy
Market and for the operation of the PJM Control Area.

     3.2  Market Buyers.

          3.2.1  Spot Market Energy.

          (b)    Generating Market Buyers shall be paid for all energy scheduled
to be delivered at the PJM Interchange Energy Market in the Day-ahead Energy
Market at the Day-ahead Prices applicable to each relevant generation bus.

          (c)    At the end of each hour during an Operating Day, the Office of
the Interconnection shall calculate the load payment at each Market Buyer's load
bus to be charged at Real-time Prices determined by the product of the hourly
Real-time Price at the relevant bus times the Market Buyer's megawatts of load
at the bus in the hour in excess of the load scheduled to be served at that bus
in the hour in the Day-ahead Energy Market. To the extent that the load actually
served at a load bus is less than the load scheduled to be served at that bus in
the Day-ahead Energy Market, the Market Buyer shall be credited for the
difference at the Real-time Price for the load bus at the time of the shortfall.
The megawatts of load at each load bus shall be the sum of the megawatts of load
for that bus of that Market Buyer as determined by the State Estimator, plus an
allocated share of transmission losses, plus any megawatts of that Market
Buyer's bilateral sales to purchasers outside the PJM Control Area attributable
to that bus. The total load charge for each Market Buyer shall be the sum, for
each of a Market Buyer's load buses, of the charges at Day-ahead Prices
determined in accordance with the Day-ahead Energy Market as specified in
Section 1.10.1a plus the charges at Real-time Prices determined as specified
herein, net of any credits specified herein for each of the Market Buyer's load
buses.

          (d)    At the end of each hour during an Operating Day, the Office of
the Interconnection shall calculate the generation revenue at each Generating
Market Buyer's generation bus to be paid at Real-time Prices, determined by the
product of the hourly Real-time Price at the relevant bus times the Generating
Market Buyer's megawatts of generation at such generation bus in the hour, as
determined by the State Estimator, in excess of the energy scheduled to be
injected at that bus in that hour in the Day-ahead Energy Market. To the extent
that the energy actually injected at the generation bus is less than the energy
scheduled to be injected at that bus in the Day-ahead Energy Market, the
Generating Market Buyer shall be debited for the difference at the Real-time
Price for the generation bus at the time of the shortfall. The megawatts of
generation at each generation bus shall be the sum of the megawatts of
generation for that bus of that Generating Market Buyer as determined by the
State Estimator, plus any megawatts of bilateral purchases of that Generating
Market Buyer from sellers outside the PJM Control Area attributable to that bus.
The total generation revenue for each Generating Market Buyer shall be the sum,
for each of the Generating Market Buyer's generation busses, of the revenues at
Day-ahead Prices determined in accordance with the Day-ahead Energy Market as
specified in Section 1.10.1A plus the revenues at Real-time Prices determined as
specified herein, net of any debits specified herein for each of the Market
Buyer's generation buses.

          (e)    At the end of each hour during an Operating Day, the Office of
the Interconnection shall calculate a net bill for each Market Buyer, determined
as the difference between its total load charges and its total generation
revenue. The portions of the net bill attributable to net hourly PJM Interchange
and to Transmission Congestion Charges in the Day-ahead Energy Market and the
Real-time Energy Market shall be determined as set forth in this Section and in
Section 5.1.3.

          (f)    At the end of each hour during an Operating Day, the Office of
the Interconnection shall calculate the total amount of net hourly PJM
Interchange for each Market Buyer, including Generating Market Buyers, in
accordance with the PJM Manuals. For Internal Market Buyers that are Load
Serving Entities or purchasing on behalf of Load Serving Entities, this
calculation shall include determination of the net energy flows from: (i) tie
lines; (ii) any generation resource the output of which is controlled by the
Market Buyer but delivered to it over another entity's Transmission Facilities;
(iii) any generation resource the output of which is controlled by another
entity but which is directly interconnected with the Market Buyer's transmission
system; (iv) deliveries pursuant to bilateral energy sales; (v) receipts
pursuant to bilateral energy purchases; (vi) the Market Buyer's allocated share
of energy purchased from another Control Area in connection with a Minimum
Generation Emergency in such other Control Area as specified in Section
3.2.6(c); and (vii) an adjustment to account for the day-ahead PJM Interchange,
calculated as the difference between scheduled withdrawals and injections by
that Market Buyer in the Day-ahead Energy Market. For Electric Distributors that
report hourly net energy flows from metered tie lines, this calculation also
shall include 500 kV transmission losses and Inadvertent Interchange allocated
to the Electric Distributor and shall exclude the energy delivered to load of
other Network Customers and Transmission Customers. For External Market Buyers
and Internal Market Buyers that are not Load Serving Entities or purchasing on
behalf of Load Serving Entities, this calculation shall determine the energy
scheduled hourly for delivery to the Market Buyer net of the amounts scheduled
by the External Market Buyer in the Day-ahead Energy Market.

          (g)    The Office of the Interconnection shall calculate Locational
Marginal Prices in the form of Day-ahead Prices and Real-time Prices for each
load and generation bus in the PJM Control Area, in accordance with Section 2 of
this Schedule.

          (h)    An Internal Market Buyer shall be charged for Spot Market
Energy purchases to the extent of its hourly net purchases from the PJM
Interchange Energy Market, determined as specified in Section 3.2.1(f) above. An
External Market Buyer shall be charged for its Spot Market Energy purchases
based on the energy delivered to it, determined as specified in Section 3.2.1(f)
above. The Office of the Interconnection shall calculate an hourly weighted
average Real-time Price for each such Market Buyer, based on the hourly average
of the Market Buyer's Real-time Prices at each bus weighted by the Market
Buyer's load deviations at the bus. The total charge shall be determined by the
product of the hourly net amount of PJM Interchange Purchases times the hourly
weighted-average Real-time Price for that Market Buyer.

          (i)    A Generating Market Buyer shall be credited as a Market Seller
for sales of Spot Market Energy to the extent of its hourly net sales into the
PJM Interchange Energy Market, determined as specified in Section 3.2.1(f)
above. The Office of the Interconnection shall calculate an hourly weighted
average Real-time Price for each such Market Seller, based on the hourly average
of the Market Sellers Real-time Prices at each bus weighted by the Market
Buyer's generation deviations at each bus. The total credit shall be determined
by the product of the hourly net amount of PJM Interchange Sales times the
hourly weighted average Real-time Price for that Market Seller.

          3.2.2  Regulation.

          (a)    Each Internal Market Buyer that is a Load Serving Entity shall
have an hourly Regulation objective equal to its pro rata share of the PJM
Control Area Regulation requirements for the hour, based on the Market Buyer's
total load in the PJM Control Area for the hour.  An Internal Market Buyer that
does not meet its hourly Regulation obligation shall be charged for Regulation
dispatched by the Office of the Interconnection to meet such obligation at the
Regulation market-clearing price determined in accordance with paragraph (c) of
this section, plus the amounts, if any, described in paragraph (f) of this
section.

          (b)    A Generating Market Buyer supplying Regulation at the direction
of the Office of the Interconnection in excess of its hourly Regulation
obligation shall be credited for each increment of such Regulation at the higher
of (i) the Regulation market-clearing price or (ii) the sum of the regulation
offer and the unit-specific opportunity cost of the resource supplying the
increment of Regulation, as determined by the Office of the Interconnection in
accordance with procedures specified in the PJM Manuals.

          (c)    The Regulation market-clearing price shall be determined at a
time to be determined by the Office of the Interconnection which shall be no
earlier than the day before the Operating Day and the market-clearing price each
hour shall be equal to the highest sum of a resource's Regulation offer plus its
estimated unit-specific opportunity costs from among the resources selected to
provide Regulation.

          (d)    In determining the Regulation market-clearing price, the
estimated unit-specific opportunity costs of a resource offering to sell
Regulation each hour shall be equal to the product of (i) the deviation of the
set point of the resource that is expected to be required in order to provide
Regulation from the resource's expected output level if it had been dispatched
in economic merit order times (ii) the absolute value of the difference between
the expected Locational Marginal Price at the generation bus for the resource
and the offer price for energy from the resource (at the megawatt level of the
Regulation set point for the resource) in the PJM Interchange Energy Market.

          (e)    In determining the credit under subsection (b) to a Generating
Market Buyer selected to provide Regulation and that actively follows the Office
of the Interconnection's Regulation signals and instructions, the unit-specific
opportunity cost of a resource shall be determined for each hour that the Office
of the Interconnection requires a resource to provide Regulation and shall be
equal to the product of (i) the deviation of the resource's output necessary to
follow the Office of the Interconnection's Regulation signals from the
resource's expected output level if it had been dispatched in economic merit
order times (ii) the absolute value of the difference between the Locational
Marginal Price at the generation bus for the resource and the offer price for
energy from the resource (at the megawatt level of the Regulation set point for
the resource) in the PJM Interchange Energy Market.

          (f)    Any amounts credited for Regulation in an hour in excess of the
Regulation market-clearing price in that hour shall be allocated and charged to
each Internal Market Buyer that does not meet its hourly Regulation obligation
in proportion to its purchases of Regulation in megawatt-hours during that hour.

on the basis of the resource's scheduled output, shall be compared to the total
value of that resource's Spot Market Energy as determined by the Day-ahead
Energy Market and the Day-ahead Prices applicable to the relevant generation bus
in the Day-ahead Energy Market. Except as provided in Section 3.2.3(n), if the
total offered price summed over all hours exceeds the total value summed over
all hours, the difference shall be credited to the Market Seller.

          (c)    The sum of the foregoing credits calculated in accordance with
Section 3.2.3(b) plus any unallocated charges from Section 3.2.3(h) and 5.1.7,
shall be the cost of Operating Reserves in the Day-ahead Energy Market.

          (d)    The cost of Operating Reserves in the Day-ahead Energy Market
shall be allocated and charged to each Market Participant in proportion to the
sum of its (i) scheduled load and accepted Decrement Bids in the Day-ahead
Energy Market in megawatt-hours for that Operating Day; and (ii) scheduled
energy sales in the Day-ahead Energy Market from within the PJM Control Area to
load outside the PJM Control Area in megawatt-hours for that Operating Day, but
not including its bilateral transactions that are dynamically scheduled to load
outside the PJM Control Area pursuant to Section 1.12.

          (e)    At the end of each Operating Day, the following determination
shall be made for each synchronized pool-scheduled resource of each Market
Seller that operates as requested by the Office of the Interconnection and that
is not committed solely for the purpose of providing spinning reserves: the
total offered price for start-up and no-load fees and Spot Market Energy,
determined on the basis of the lesser of the resource's (i) hourly output as
determined by the State Estimator, or (ii) requested output as determined by the
PJM dispatch. The total offered price shall be compared to the total value of
that resource's energy in the Day-ahead Energy Market plus any credit or charge
for quantity deviations, at PJM dispatch direction, from the Day-ahead Energy
Market during the Operating Day. Except as provided in Section 3.2.3(m), if the
total offered price exceeds the total value, the difference less any credit as
determined pursuant to Section 3.2.3(b) and less any amounts credited for
Regulation in excess of the Regulation offer plus the resources opportunity
cost, shall be credited to the Market Seller.

          (f)     A Market Seller's pool scheduled resource the output of which
is reduced or suspended at the request of the Office of the Interconnection for
the purpose of maintaining reliability within the PJM Control Area, shall be
credited in an amount equal to (PAG - AG) x LT x (ULMP - UB) where:

          PAG equals the actual generation of the unit for the five minute
          period preceding the request;

including the bus at each point of interconnection between the PJM Control Area
and each adjacent Control Area, in accordance with Section 2 of this Schedule.

          (d)       A Market Seller shall be credited for Real-time sales of
Spot Market Energy to the extent of its hourly net deliveries to the PJM Control
Area of energy in excess of amounts scheduled in the Day-ahead Energy Market
from the Market Seller's resources. For pool External Resources, the Office of
the Interconnection shall model, based on an appropriate flow analysis, the
hourly amounts delivered from each such resource to the corresponding interface
point between the PJM Control Area and adjacent Control Areas. The total real-
time generation revenues for each Market Seller shall be the sum of its credits
determined by the product of (i) the hourly net amount of energy delivered to
the PJM Control Area at the applicable generation or interface bus in excess of
the amount scheduled to be delivered in that hour at that bus in the Day-ahead
Energy Market from each of the Market Seller's resources, times (ii) the hourly
Real-time Price at that bus. To the extent that the energy actually injected at
a generation or interface bus in any hour is less than the energy scheduled to
be injected at that bus in the Day-ahead Energy Market, the Market Seller shall
be debited for the difference at the Real-time Price for the applicable bus at
the time of the shortfall times the amount of the shortfall. The total
generation revenue for each Market Seller shall be the sum, for each of the
Market Seller's generation or interface buses, of the revenues at Day-ahead
Prices determined in accordance with the Day-ahead Energy Market as specified in
Section 3.3.1(a) plus the revenues at Real-time Prices determined as specified
herein, net of any debits specified herein for each of the Market Seller's
generation or interface buses.

pursuant to a written agreement with the LLC to sell energy on a comparable
basis to the PJM Control Area, and (ii) only to the extent consistent with the
maintenance of reliability in the PJM Control Area.  The Office of the
Interconnection may decline to make such sales to a Control Area that the Office
of the Interconnection determines does not have in place and implement Emergency
procedures that are comparable to those followed in the PJM Control Area.  If
the Office of the Interconnection sells energy to an interconnected Control Area
as necessary to alleviate or end an Emergency in that Control Area, such energy
shall be sold at 150% of the Real-time Price at the bus or busses at the border
of the PJM Control Area at which such energy is delivered.

          3.5.2  Operating Margin Sales.

          The extent appropriate in accordance with Good Utility Practice, the
Office of the Interconnection may sell Operating Margin to an interconnected
Control Area as requested to alleviate an operating contingency resulting from
the affect of the purchasing Control Area's operations on the dispatch of
resources in the PJM Control Area.  Such sales shall be made only to Control

          3.6.3  500 kV Meter Errors.

          Billing cycle accounting for 500 kV transmission losses shall be
adjusted to account for errors in meters on 500 kV Transmission Facilities.

          3.6.4  Meter Corrections Between Control Areas.

          An error between accounted for and metered interchange between a Party
in the PJM Control Area and an entity in another Control Area shall be corrected
by adjusting the hourly meter readings.  If this is not practical, the error
shall be accounted for by a correction at the end of the billing cycle.  The
Market Participant with ties to such other Control Area experiencing the error
shall account for the full amount of the discrepancy and an appropriate debit or
credit shall be applied equally among all Market Buyers.  The Office of the
Interconnection will adjust the actual interchange between the PJM Control Area
and the other Control Area to maintain a proper record of inadvertent energy
flow.  Meter corrections on the 500 kV system between the PJM Control Area and
other Control Areas shall be accounted for through the internal 500 kV system
meter error allocation at the end of the billing cycle.

          3.6.5  Meter Correction Data.

          Meter error data shall be submitted to the Office of the
Interconnection not later than noon on the second working day of the Office of
the Interconnection after the end of the billing cycle applicable to the meter
correction.

     5.   CALCULATION OF TRANSMISSION CONGESTION CHARGES AND
                             CREDITS

          5.1  Transmission Congestion Charge Calculation.

               5.1.1     Calculation by Office of the Interconnection.

               When the transmission system is operating under constrained
conditions, the Office of the Interconnection shall calculate Transmission
Congestion Charges for each Network Service User, the PJM Interchange Energy
Market, and each Transmission Customer.

               5.1.2     General.

               The basis for the Transmission Congestion Charges shall be the
differences in the Locational Marginal Prices between points of delivery and
points of receipt, as determined in accordance with Section 2 of this Schedule.

               5.1.3     Network Service User Calculation.

               Each Network Service User shall be charged for the increased cost
of energy incurred by it during each constrained hour to deliver the output of
its firm Capacity Resources or other owned or contracted for resources, its firm
bilateral purchases, and its non-firm bilateral purchases as to which it has
elected to pay Transmission Congestion Charges. The Transmission Congestion
Charge for deliveries from each such source shall be the Network Service User's
hourly net bill less its hourly net PJM Interchange payments or sales as
determined in accordance with Section 3.2.1 or Sections 3.3 and 3.3.1 of this
Schedule.

          5.1.4     Transmission Customer Calculation.

          Each Transmission Customer using Firm Point-to-Point Transmission
Service (as defined in the PJM Tariff), and each Transmission Customer using
Non-Firm Point-to-Point Transmission Service (as defined in the PJM Tariff) that
has elected to pay Transmission Congestion Charges, shall be charged for the
increased cost of energy during constrained hours for the delivery of energy
using Point-to-Point Transmission Service.  Except as specified in this
subsection, a Transmission Congestion Charge shall be assessed for transmission
use scheduled in the Day-ahead Energy Market, calculated as the amount to be
delivered multiplied by the difference between the Day-ahead Price at the
delivery point or PJM Control Area boundary delivery interface and the Day-ahead
Price at the source point or PJM Control Area boundary source interface.
Transmission Congestion Charges shall be assessed for real-time transmission use
in excess of the amounts scheduled for each hour in the Day-ahead Energy Market,
calculated as the excess amount multiplied by the difference between the Real-
time Price at the delivery point or PJM Control Area boundary delivery
interface, and the Real-time Price at the source point or PJM Control Area
boundary source interface.  A Transmission Customer shall be credited for
Transmission Congestion Charges for real-time transmission use falling below the
amounts scheduled for each hour in the Day-ahead Energy Market, calculated as
the shortfall amount multiplied by the difference between the Real-time Price at
the delivery point or PJM Control Area boundary delivery interface, and the
Real-time Price at the source point or PJM Control Area boundary source
interface.  Real-time deviations from the Point-to-Point Transmission Service
scheduled in the Day-ahead Energy Market shall be determined by the lesser of
the real-time injection or withdrawal associated with such transmission service.
The Transmission Congestion Charge for Market Sellers using point-to-point
transmission service for deliveries out of the PJM Control Area from generating
resources within the PJM Control Area shall be the amount of its net bill less
the Market Seller's net hourly PJM Interchange payments or sales as determined
in accordance with Section 3.3 of this Schedule.

          5.1.5     Operating Margin Customer Calculation.

          Each Control Area purchasing Operating Margin shall be assessed
Transmission Congestion Charges for any the increase in the cost of energy
resulting from the provision of Operating Margin.  The Transmission Congestion
Charge shall be the amount of Operating Margin purchased in an hour multiplied
by the difference in the Real-time Price at what would be the delivery interface
and the Real-time Price at what would be the source interface, if the operating
contingency that was the basis for the purchase of Operating Margin had occurred
in that hour.  Operating Margin may be allocated among multiple source and
delivery interfaces in accordance with an applicable load flow study.

          5.1.6     Transmission Loading Relief Customer Calculation.

     (a)  Each Transmission Loading Relief Customer shall be assessed
Transmission Congestion Charges for any increase in the cost of energy in the
PJM Control Area resulting from its energy schedules over contract paths outside
the PJM Control Area during Transmission Loading Relief.

     (b) The Transmission Congestion Charge shall be the total amount of energy
specified in such energy schedules multiplied by the difference between a
Locational Marginal Price calculated by the Office of the Interconnection for
the energy schedule source location specified in the NERC Interchange
Distribution Calculator and a Locational Marginal Price calculated by the Office
of the Interconnection for the energy schedule sink location specified in the
NERC Interchange Distribution Calculator.  Transmission Congestion Charges that
are less than zero shall be set equal to zero for Transmission Loading Relief
Customers.

     (c) The Office of the Interconnection will determine the Locational
Marginal Prices at the energy schedule source and sink locations external to PJM
with reference to and based solely on the prices of energy in the PJM Control
Area and at the interface buses between the PJM Control Area and adjacent
Control Areas and the system conditions and actual power flow distributions as
described by the PJM State Estimator program.  The Office of the Interconnection
will determine the Locational Marginal Prices at the external energy schedule
source and sink locations and the resulting Congestion Charge based on the
portion of the energy schedule that flows through the PJM Control Area as
reflected by the flow distributions from the PJM State Estimator program.

          5.1.7     Total Transmission Congestion Charges.

          The total Transmission Congestion Charges collected by the Office of
the Interconnection each hour will be the aggregate net amounts determined as
specified in this Schedule.  The Office of the Interconnection shall collect
Transmission Congestion Charges for each hour the transmission system operates
under constrained conditions.

     5.2  Transmission Congestion Credit Calculation.

          5.2.1     Eligibility.

          (a)       Except as provided in Section 5.2.1(b), each holder of a
Fixed Transmission Right shall receive as a Transmission Congestion Credit a
proportional share of the total Transmission Congestion Charges collected for
each constrained hour.

          (b)       If a holder of a Fixed Transmission Right between specified
delivery and receipt buses acquired the Fixed Transmission Right in a Fixed
Transmission Rights Auction (the procedures for which are set forth in Part 7 of
this Schedule 1) and (i) had an Increment Bid and/or Decrement Bid that was
accepted by the Office of the Interconnection for an applicable hour in the Day-
ahead Energy Market for delivery or receipt at or near delivery or receipt buses
of the Fixed Transmission Right; and (ii) the result of the acceptance of such
Increment Bid or Decrement Bid is that the difference in locational marginal
prices in the Day-ahead Energy Market between such delivery and receipt buses is
greater than the difference in locational marginal prices between such delivery
and receipt buses in the Real-time Energy Market, then the Market Participant
shall not receive any Transmission Congestion Credit, associated with such Fixed
Transmission Right in such hour, in excess of one divided by the number of hours
in the applicable month multiplied by the amount that the Market Participant
paid for the Fixed Transmission Right in the Fixed Transmission Rights Auction.

          (b)       Subject to the provisions of Section B of Attachment K of
the PJM Tariff, on an annual basis by such deadline established by the Office of
the Interconnection, each Network Service User shall designate a subset of its
Network Resources for which Fixed Transmission Rights will be assigned. Fixed
Transmission Rights shall be assigned for each Network Resource in a number of
megawatts equal to or less than the installed capacity summer megawatt rating of
each designated Network Resource, determined at the PJM Control Area
transmission bus at which the designated Network Resource is connected. Each
Fixed Transmission Right shall be to the aggregate load busses of the Network
Service User in a Zone or, with respect to Non-Zone Network Load, to the border
of the PJM Control Area. The sum of each Network Service User's assigned Fixed
Transmission Rights for a Zone must be equal to or less than the Network Service
User's peak load for that Zone as determined under Section 34.1 of the Tariff.
The sum of each Network Service User's Fixed Transmission Rights for Non-Zone
Network Load must be equal to or less than the Network Service User's
transmission responsibility for Non-Zone Network Load as determined under
Section 34.1 of the Tariff.

          (c)       Each Transmission Customer receiving firm Point-to-Point
Transmission Service shall be assigned Fixed Transmission Rights; provided,
however, that a Transmission Customer may notify the Office of Interconnection
that it does not wish to receive any FTRs or wishes to receive FTRs only for
certain Point or Points of Receipt and Point or Points of Delivery, in which
event no FTRs or such reduced amount of FTRs shall be issued to the Transmission
Customer.  The Fixed Transmission Right for each instance of Point-to-Point
Transmission Service shall be a number of megawatts equal to the megawatts of
firm service being provided between the receipt and delivery points as to which
the Transmission Customer has firm Point-to-Point Transmission Service.

          (d)       A Fixed Transmission Right, or the right to Transmission
Congestion Credits attributable to a Fixed Transmission Right, may be sold or
otherwise transferred by agreement, subject to compliance with such procedures
as may be established by the Office of the Interconnection for verification of
the rights of the purchaser or transferee.

          5.2.3     Target Allocation for Network Service Users.

          A target allocation of Transmission Congestion Credits for each
Network Service User shall be determined for each of its Fixed Transmission
Rights.  Each Fixed Transmission Right shall be multiplied by the percent of the
Network Service User's annual peak load assigned to each load bus multiplied by
the difference calculated as the Network Service User's load bus Day-ahead Price
minus the generation bus Day-ahead Price of the Network Resource associated with
the Fixed Transmission Right.  The total target allocation for each Fixed
Transmission Right is the sum of the target allocations for each load bus.  The
total target allocation for each Network Service User for each hour is the sum
of the total target allocations for each of the Network Service User's Fixed
Transmission Rights.

          5.2.4     Target Allocation for other Holders.

          A target allocation of Transmission Congestion Credits for each
Transmission Customer or entity holding an FTR acquired by other means shall be
determined for each Fixed Transmission Right.  Each Fixed Transmission Right
shall be multiplied by the Day-ahead Price differences for the receipt and
delivery points associated with the Fixed Transmission Right, calculated as the
Day-ahead Price at the delivery point(s) minus the Locational Marginal Price at
the receipt point(s).  The total target allocation for the Transmission Customer
for each hour shall be the sum of the target allocations associated with all of
the Transmission Customer's Fixed Transmission Rights.

          5.2.5     Calculation of Transmission Congestion Credits.

          (a)       The total of all the target allocations determined as
specified above shall be compared to the total Transmission Congestion Charges
in each hour resulting from both the Day-ahead Energy Market and the Real-time
Energy Market. If the total of the target allocations is less than the total of
the Transmission Congestion Charges, the Transmission Congestion Credit for each
Network Service User and Transmission Customer shall be equal to its target
allocation. All remaining Transmission Congestion Charges shall be distributed
as described below in Section 5.2.6 "Distribution of Excess Congestion Charges."

          (b)       If the total of the target allocations is greater than the
total Transmission Congestion Charges for the hour resulting from both the Day-
ahead Energy Market and the Real-time Energy Market, each holder of Fixed
Transmission Rights shall be assigned a share of the total Transmission
Congestion Charges in proportion to its target allocations.

          5.2.6     Distribution of Excess Congestion Charges.

          (a)       Excess Transmission Congestion Charges accumulated in a
month shall be distributed to each holder of Fixed Transmission Rights in
proportion to, but not more than, any deficiency in the share of Transmission
Congestion Charges received by the holder during that month as compared to its
total target allocations for the month.

          (b)       After the excess Transmission Congestion Charge distribution
described in Section 5.2.6(a) is performed, any excess Transmission Congestion
Charges remaining at the end of a month shall be distributed to each holder of
Fixed Transmission Rights in proportion to, but not more than, any deficiency in
the share of Transmission Congestion Charges received by the holder during the
current calendar year, including previously distributed excess Transmission
Congestion Charges, as compared to its total target allocation for the calendar
year.
          (c)       Any excess Transmission Congestion Charges remaining at the
end of a calendar year shall be distributed to Network Service Users and
Transmission Customers purchasing Firm Point-to-Point Transmission Service in
proportion to their Demand Charges for Network Service and their charges for
Reserved Capacity for Firm Point-to-Point Transmission Service.

          6.        "MUST-RUN" FOR RELIABILITY GENERATION

     6.1  Introduction.

     The following procedures shall apply to any generation resource subject to
the dispatch of the Office of the Interconnection that (a) is a generation
resource for which construction commenced before July 9, 1996, and (b) as a
result of transmission constraints, the Office of the Interconnection
determines, in the exercise of Good Utility Practice, must be run in order to
maintain the reliability of service in the PJM Control Area.  The provisions of
this Schedule shall otherwise apply to the scheduling, dispatch, operation and
accounting treatment of such resources, to the extent not inconsistent with the
provisions of this Section 6.

     6.2  Identification of Facility Outages.

     Not later than one hour prior to the deadline specified in Section 1.10.1
of this Schedule, the Office of the Interconnection shall identify on the PJM
Open Access Same-Time Information System any facility outage or other system
condition which it has determined may give rise to a transmission constraint
that may require, in order to maintain system reliability, the dispatch of one
or more generation resources that otherwise would not be dispatched based on the
merits of their offers to the PJM Interchange Energy Market.

     6.3  Dispatch for Local Reliability.

          6.3.1     Request and Dispatch.

          In addition to the dispatch of generation by the Office of the
Interconnection to maintain reliability on transmission facilities directly
monitored by it, a Member that owns or leases with rights equivalent to
ownership Transmission Facilities as defined in this Agreement or the
Transmission Owners Agreement and that operates a local control center in
accordance with Section 11.3.3 of this Agreement or a Market Operations Center
in accordance with Section 1.7.5 of this Schedule, may request the Office of the

monitored by the Office of the Interconnection, subject to the rules and
procedures in Section 6.3.2.  The Office of the Interconnection shall dispatch
generation to maintain reliability on such Transmission Facilities by
incorporating the facilities in the State Estimator program described in Section
2.3 as set forth below, unless the Office of the Interconnection determines that
such dispatch would adversely affect reliability in the PJM Control Area or
would otherwise not be in accordance with Good Utility Practice.

          6.3.2     Designation of Facilities.

          The following rules and procedures shall apply to a Member request
that the Office of the Interconnection dispatch generation on one or more
Transmission Facilities that are not then directly monitored by the Office of
the Interconnection.

     a)   The Transmission Facilities that are the subject of the request must
          be among the facilities that comprise the Transmission System under
          the PJM Tariff;

     b)   The Member shall provide modeling information for such Transmission
          Facilities and provide sufficient telemetry to the Office of the
          Interconnection such that power flows are observable by the State
          Estimator program described in Section 2.3; provided, however, that if
          an unreliable constrained condition exists and time does not permit
          such modeling and telemetry, the Member and the Office of the
          Interconnection may agree to use a representative surrogate for such
          Transmission Facilities in order to allocate the costs of the dispatch
          of generation using Locational Marginal Prices to maintain reliability
          on such Transmission Facilities, provided further that the Member
          shall expeditiously provide the modeling data and install the
          necessary facilities to incorporate the Transmission Facilities into
          the State Estimator program;

     c)   The request shall constitute a request that such Transmission
          Facilities become and remain monitored by the Office of the
          Interconnection and subject to its dispatch control for a period of
          not less than ninety (90) days;

     d)   The Member shall comply with all other operating procedures
          established by the Office of the Interconnection regarding dispatch
          for local reliability as set forth in the PJM Manuals.

     6.4  Price Caps.

          6.4.1     Applicability.

          (a)       Except as specified below, if in the day-ahead schedule
determined by the Office of the Interconnection in accordance with Sections
1.10.8(a) and (b) of this Schedule any generation resource may be dispatched out
of economic merit order to maintain system reliability as a result of limits on
transmission capability, the prices for energy offered by such resource shall be
capped at the levels specified below. If the Office of the Interconnection is
able to do so, such prices shall be capped only during each hour when the
transmission limit affects the schedule of the affected resource, and otherwise
shall be capped for the entire Operating Day. The energy prices as capped shall
be used to determine any Locational Marginal Price affected by the price of such
resource.

Locational Marginal Price affected by the price of such resource.

          (c)       Generation resources subject to a price cap shall be paid
for energy at the applicable Locational Marginal Price.

          (d)       Price caps shall not be applicable to generation resources
used to relieve the Western, Central and Eastern reactive limits in the PJM
Control Area. In addition, price caps shall not be applicable to generation
resources used to relieve any other transmission limit as to which the FERC has
authorized the use of market based rates.

          6.4.2     Level.

          The price cap shall be one of the amounts specified below, as
specified in advance by the market Seller for the affected unit:

          (i)       The weighted average Locational Marginal Price at the
     generation bus at which energy from the capped resource was delivered
     during a specified number of hours during which the resource was dispatched
     for energy in economic merit order, the specified number of hours to be
     determined by the Office of the Interconnection and to be a number of hours
     sufficient to result in a price cap that reflects reasonably
     contemporaneous competitive market conditions for that unit;

          (ii)      The incremental operating cost of the generation resource as
                    determined in accordance with Schedule 2 of this Agreement
                    and the PJM Manuals, plus 10% of such costs; or

          (iii)     An amount determined by agreement between the Office of the
                    Interconnection and the Market Seller.

First Revised Rate Schedule FERC No. 24

          7.1.1     Auction Period and Scope of Auctions.

          The period covered by an auction shall be the one-month period next
following the date that the auction is conducted.  The Office of the
Interconnection shall offer for sale in the auction any remaining Fixed
Transmission Rights capability for the month after taking into account all of
the Fixed Transmission Rights already outstanding at the time of the auction.
In addition, any holder of a Fixed Transmission Right for the period covered by
an auction may offer such Fixed Transmission Right for sale in such auction.
Each monthly auction will consist of a separate auction for on-peak Fixed
Transmission Rights and a separate auction for off-peak Fixed Transmission
Rights.  Market Participants may bid for and acquire any number of Fixed
Transmission Rights, provided that all Fixed Transmission Rights awarded are
simultaneously feasible with each other and with all Fixed Transmission Rights
outstanding at the time of the auction and not sold into the auction.

          7.1.2     Frequency and Time of Auctions.

          Fixed Transmission Rights auctions shall be held monthly.  The bid and
offer period shall open at 12:00 midnight (Eastern Prevailing Time) on the
fifteenth (15th) business day preceding the month for which Fixed Transmission
Rights are being auctioned and shall close at 12:00 midnight (Eastern Prevailing
Time) on the tenth (10th) business day preceding the month for which Fixed
Transmission Rights are being auctioned.

          7.1.3     Duration of Fixed Transmission Rights.

          Each Fixed Transmission Right acquired in a Fixed Transmission Rights
auction shall entitle the holder to credits of Transmission Congestion Charges
for the one-month period for which the Fixed Transmission Rights were auctioned.

     7.2  Fixed Transmission Rights Characteristics.

          7.2.1     Reconfiguration of Fixed Transmission Rights.

          Through an appropriate linear programming model, the Office of the
Interconnection shall reconfigure the Fixed Transmission Rights offered or
otherwise available for sale in any auction to maximize the value to the bidders
of the Fixed Transmission Rights sold, provided that any Fixed Transmission
Rights acquired at auction shall be simultaneously feasible in combination with
those Fixed Transmission Rights outstanding at the time of the auction and not
sold in the auction.  The linear programming model shall, while respecting
transmission constraints and the maximum MW quantities of the bids and offers,
select the set of simultaneously feasible Fixed Transmission Rights with the
highest net total auction value as determined by the bids of buyers and taking
into account the reservation prices of the sellers.

          7.2.2     Specified Buses.

          Auction bids for Fixed Transmission Rights may specify any combination
of receipt and delivery buses represented in the State Estimator model for which
the Office of the Interconnection calculates and posts Locational Marginal
Prices.  Auction bids may specify receipt and delivery points from locations
outside of the PJM Control Area to locations inside the PJM Control Area, from
locations within the PJM Control Area to locations outside of the PJM Control
Area, or to and from locations within the PJM Control Area.

          7.2.3     Transmission Congestion Charges.

          Fixed Transmission Rights, whether acquired at auction or otherwise,
shall entitle holders thereof to credits only for Transmission Congestion
Charges, and shall not confer a right to credits for payments arising from or
relating to transmission congestion made to any entity other than the Office of
the Interconnection.

     7.3  Auction Procedures.

          7.3.1     Role of the Office of the Interconnection.

          Fixed Transmission Rights auctions shall be conducted by the Office of
the Interconnection in accordance with standards and procedures set forth in the
PJM Manuals, such standards and procedures to be consistent with the
requirements of this Schedule.

          7.3.2     Notice of Offer.

          A holder of a Fixed Transmission Right wishing to offer the Fixed
Transmission Right for sale shall notify the Office of the Interconnection of
any Fixed Transmission Rights to be offered.  Each Fixed Transmission Right sold
in an auction shall, at the end of the period for which the Fixed Transmission
Rights were auctioned, revert to the offering holder or the entity to which the
offering holder has transferred such Fixed Transmission Right, subject to the
term of the Fixed Transmission Right itself and to the right of such holder or
transferee to offer the Fixed Transmission Right in the next or any subsequent
auction during the term of the Fixed Transmission Right.

          7.3.3     Pending Applications for Firm Service.

          (a)       Prior to the start of each auction bidding period, the
Office of the Interconnection shall exert reasonable effort to complete its
review of pending applications for Network Transmission Service and Firm Point-
to-Point Transmission Service and to ascertain the corresponding Fixed
Transmission Rights to be assigned to the entities receiving such service,
subject to compliance with all applicable deadlines and other procedures by the
applicant. Fixed Transmission Rights so assigned shall be included in the
simultaneous feasibility test performed by the Office of the Interconnection for
the auction.

          (b)       Fixed Transmission Rights may be assigned to entities
requesting Network Transmission Service or Firm Point-to-Point Transmission
Service only if such Fixed Transmission Rights are simultaneously feasible with
all outstanding Fixed Transmission Rights, including Fixed Transmission Rights
effective for the then-current auction period. If an assignment of Fixed
Transmission Rights pursuant to a pending application for Network Transmission
Service or Firm Point-to-Point Transmission Service cannot be completed prior to
an auction, Fixed Transmission Rights attributable to such transmission service
shall not be assigned for the then-current auction period. If a Fixed
Transmission Right cannot be assigned for this reason, the applicant may
withdraw its application, or request that the Fixed Transmission Right be
assigned effective with the start of the next auction period.

          7.3.4     On-Peak and Off-Peak Periods.

          The Office of the Interconnection will conduct separate auctions
simultaneously for on-peak and off-peak periods.  On-Peak Fixed Transmission
Rights shall cover the periods from 7:00 a.m. up to the hour ending at 11:00
p.m. on Mondays through Fridays, except holidays as defined in the PJM Manuals.
Off-Peak Fixed Transmission Rights shall cover the periods from 11:00 p.m. up to
the hour ending 7:00 a.m. on Mondays through Fridays and all hours on Saturdays,
Sundays, and holidays as defined in the PJM Manuals.  Each bid shall specify
whether it is for an on-peak or off-peak period.

          7.3.5     Offers and Bids.

          (a)       Offers to sell and bids to purchase Fixed Transmission
Rights shall be submitted during the period set forth in Section 7.1.2, and
shall be in the form specified by the Office of the Interconnection in
accordance with the requirements set forth below.

          (b)       Offers to sell shall identify the specific Fixed
Transmission Right, by megawatt quantity and receipt and delivery points,
offered for sale. An offer to sell a specified megawatt quantity of Fixed
Transmission Rights shall constitute an offer to sell a quantity of Fixed
Transmission Rights equal to or less than the specified quantity. An offer to
sell may not specify a minimum quantity being offered. Each offer may specify a
reservation price, below which the offeror does not wish to sell the Fixed
Transmission Right. Offers submitted by entities holding rights to Fixed
Transmission Rights acquired other than by assignment in connection with
reservations of Network Transmission Service or Firm Point-to-Point Transmission
Service shall be subject to such reasonable standards for the verification of
the rights of the offeror as may be established by the Office of the
Interconnection. Offers shall be subject to such reasonable standards for the
creditworthiness of the offeror or for the posting of security for performance
as the Office of the Interconnection shall establish.

          (c)       Bids to purchase shall specify the megawatt quantity, price
per megawatt, and receipt and delivery points of the Fixed Transmission Right
that the bidder wishes to purchase. A bid to purchase a specified megawatt
quantity of Fixed Transmission Rights shall constitute a bid to purchase a
quantity of Fixed Transmission Rights equal to or less than the specified
quantity. A bid to purchase may not specify a minimum quantity that the bidder
wishes to purchase. A bid may specify as receipt or delivery points any bus for
which the Office of the Interconnection calculates and posts Locational Marginal
Prices in accordance with Section 2 of this Schedule and may include Fixed
Transmission Rights for which the associated Transmission Congestion Credits may
have negative values. Bids shall be subject to such reasonable standards for the
creditworthiness of the bidder or for the posting of security for performance as
the Office of the Interconnection shall establish.

          (d)       Bids and offers shall be specified to the nearest tenth of a
megawatt and shall be greater than zero.

          7.3.6     Determination of Winning Bids and Clearing Price.

          (a)       At the close of the bidding period each month, the Office of
the Interconnection will create a base Fixed Transmission Rights power flow
model that includes all outstanding Fixed Transmission Rights that have been
approved and confirmed for any portion of the month for which the auction was
conducted and that were not offered for sale in the auction. The base Fixed
Transmission Rights model also will include estimated uncompensated parallel
flows into each interface point of the PJM Control Area and estimated scheduled
transmission outages.

          (b)       In accordance with the requirements of Section 7.4 of this
Schedule and subject to all applicable transmission constraints and reliability
requirements, the Office of the Interconnection shall determine the simultaneous
feasibility of all outstanding Fixed Transmission Rights not offered for sale in
the auction and of all Fixed Transmission Rights that could be awarded in the
auction for which bids were submitted.  The winning bids shall be determined
from an appropriate linear programming model that, while respecting transmission
constraints and the maximum MW quantities of the bids and offers, selects the
set of simultaneously feasible Fixed Transmission Rights with the highest net
total auction value as determined by the bids of buyers and taking into account
the reservation prices of the sellers.  In the event that there are two or more
identical bids for the selected Fixed Transmission Rights and there are
insufficient Fixed Transmission Rights to accommodate all of the identical bids,
then each such bidder will receive a pro rata share of the Fixed Transmission
Rights that can be awarded.

          (c)       Fixed Transmission Rights shall be sold at the market-
clearing price for Fixed Transmission Rights between specified pairs of receipt
and delivery points, as determined by the bid value of the marginal Fixed
Transmission Right that could not be awarded because it would not be
simultaneously feasible. The linear programming model shall determine the
clearing prices of all Fixed Transmission Rights paths based on the bid value of
the marginal Fixed Transmission Rights, which are those Fixed Transmission
Rights with the highest bid values that could not be awarded fully because they
were not simultaneously feasible, and based on the flow sensitivities of each
Fixed Transmission Rights path relative to the marginal Fixed Transmission
Rights paths flow sensitivities on the binding transmission constraints.

          7.3.7     Announcement of Winners and Prices.

          Within two (2) business days after the close of an auction, the Office
of the Interconnection shall post the winning bidders, the megawatt quantity,
and the receipt and delivery points for each Fixed Transmission Right awarded in
the auction and the price at which each Fixed Transmission Right was awarded.
Results of the on-peak auction and off-peak auction will be posted separately.
The Office of the Interconnection shall not disclose the price specified in any
bid to purchase or the reservation price specified in any offer to sell.

          7.3.8     Auction Settlements.

          All buyers and sellers of Fixed Transmission Rights between the same
points of receipt and delivery shall pay or be paid the market-clearing price,
as determined in the auction, for such Fixed Transmission Rights.

          7.3.9     Allocation of Auction Revenues.

          All auction revenues, net of payments to entities selling Fixed
Transmission Rights into the auction, shall be allocated among the Regional
Transmission Owners in proportion to their respective transmission revenue
requirements.

     7.4  Simultaneous Feasibility.

     The Office of the Interconnection shall make the simultaneous feasibility
determinations specified herein using appropriate powerflow models of
contingency-constrained dispatch.  Such determinations shall take into account
outages of both individual generation units and transmission facilities and
shall be based on reasonable assumptions about the configuration and
availability of transmission capability during the period covered by the auction
that are not inconsistent with the determination of the deliverability of
Capacity Resources under the Reliability Assurance Agreement.  The goal of the
simultaneous feasibility determination shall be to ensure that there are
sufficient revenues from Transmission Congestion Charges to satisfy all Fixed
Transmission Rights obligations for the auction period under expected
conditions.

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

     (a)  Each Market Participant obligated to sell operating capacity on the
PJM Interchange Energy Market at cost-based rates shall include the following
components or their equivalent in the determination of costs for operating
capacity supplied to or from the Interconnection:

     (1)  Boilers
          -------
          Firing-up cost;
          No-load cost during period of operation;
          Peak-prepared-for maintenance cost;
          Incremental labor cost; and
          Other incremental operating costs.
     (2)  Machines
          --------
          Starting cost from cold to synchronized operation;
          No-load cost during period of operation;
          Incremental labor cost; and
          Other incremental operating costs.

     (b)  Each Member obligated to sell energy on the PJM Interchange Energy
Market at cost-based rates shall include the following components or their
equivalent in the determination of costs for energy supplied to the
Interconnection:

          Incremental fuel cost;
          Incremental maintenance cost;
          Incremental labor cost; and
          Other incremental operating costs.

     (c)  All fuel costs shall employ the marginal fuel price experienced by the
Member.

     (d)  The PJM Board, upon consideration of the advice and recommendations of
the Members Committee, shall from time to time define in detail the method of
determining the costs entering into the said components, and the Members shall
adhere to such definitions in the preparation of incremental costs used on the
Interconnection.

                            SCHEDULE 2 -- EXHIBIT A
                            ----------    ---------
                 EXPLANATION OF THE TREATMENT OF THE COSTS OF
                 --------------------------------------------
                              EMISSION ALLOWANCES
                              -------------------

     The cost of emission allowances is included in "Other Incremental Operating
Costs" pursuant to Schedule 2. The replacement cost of emission allowances will
be used to recover the cost of emission allowances consumed as a result of
producing energy for the Interconnection.

Index
-----

     Consistent with definitions promulgated by the PJM Board upon consideration
of the advice and recommendations of the Members Committee under Schedule 2,
each Member subject to Schedule 2 will determine and provide to the
Interconnection its replacement cost of emission allowances, such cost to be an
amount not exceeding the market price index published by Cantor-Fitzgerald
Environmental Brokerage Services ("EBS"), or a PJM Board approved index in the
event that EBS should cease publication of such index.  As with all other
components of cost required for accounting under this Agreement, each Member
subject to Schedule 2 will use the same replacement cost of emissions
allowances, so determined, as it uses for coordinating operation of its
generating facilities hereunder.

     For each Member subject to Schedule 2, the cost of emissions allowances is
included in the cost of energy supplied to or received from the Interconnection.

Payment
-------

     The Members subject to Schedule 2 waive the right of payment-in-kind for
emission allowances for transactions wholly between the parties.  Cash payments
for emission allowances consumed in providing energy for the Interconnection
shall be incorporated into and conducted pursuant to the billing procedures for
energy prescribed by this Agreement.

Calculation of Emission Allowance Amount and Cost
-------------------------------------------------

     Pursuant to the letter from the PJM Interconnection to FERC dated June 26,
1995, the calculation of an annual average for the cost of emission allowances,
described below, is required due to the profile of the PJM physical system and
PJM Energy Management software system.  Approximately five hundred and forty
generating units comprise the PJM system, of which 9 units are Phase I units.
Current real-time operational software and hardware tools used in the
transaction of energy do not identify individual units, and therefore do not
identify Phase I units. (The pool has contracted with a vendor to supply a new
Energy Management System to be installed over the next several years.)  It is
currently not possible for system operators to provide actual individual unit
emission allowance costs in real time transaction quotations.

     An average emission allowance cost based on a standard production cost
study case will be used to calculate the average cost of emission allowances for
each pool megawatt produced.  This cost for the current year is less than 0.2
dollars per megawatt-hour.

     In summary, for the above-mentioned reasons, it is not practical nor cost
effective to provide actual individual emission allowance costs in real-time
transaction quotations.  Therefore, the annual average method is proposed.

     The Emission Allowances (Tons of SO\\2\\)associated with a transaction will
be calculated by multiplying the magnitude of a transaction (MWhr) by an
Emissions per MWHr Factor (Tons of SO\\2\\ per MWhr):

   Emission             Transaction       Emissions
   Allowances           =    Magnitude    x     per MWhr
   Used                                         Factor
   (Tons of S0\\2\\)         (MWhr)       (Tons of S0\\2\\ per MWhr)

     The Emissions per MWHr Factor will be calculated by dividing the forecast
annual emissions from all Phase I units (Tons of S0\\2\\) by the Forecast Annual
Total PJM Energy Production (MWhr):

          Emissions
          per MWhr   =    Forecast Annual Phase I Unit Emissions (Tons of
                          -----------------------------------------------
          S0\\2\\)
          --------
          Factor     Forecast Annual Total PJM Energy Production
          (MWhr)
          (Tons of S0\\2\\
          per MWhr)

     Likewise, the cost (Dollars) of the Emission Allowances for a transaction
will be calculated by multiplying the transaction magnitude (MWhr) by a Charge
per MWhr Factor (Dollars per MWHr).

Cost of Emission        Transaction              Charge
Allowances Used         =      Magnitude    x    per MWhr Factor
(Dollars)                      (MWhr)                  (Dollars per MWhr)


     The Charge per MWhr Factor will be calculated by multiplying, for each
Member subject to Schedule 2, its Forecast Annual Emissions (Tons of S0\\2\\)by
its respective Emissions Allowance Replacement Cost (Dollars per Ton of S0\\2\\)
to yield each the forecasted annual cost of emissions (Dollars).  Then, the
total of forecasted annual cost of emissions for each Member subject to Schedule
2 is divided by the Forecast Annual Total PJM Energy Production (MWhr) to
determine the Charge per MWHr Factor (Dollars per MWHr).

          Charge per
          MWhr Factor     =        (sum of) (A x B)   ,    where:
                                            -------
                 C
          A = Member's Forecasted Annual Emissions, (Tons of S0\\2\\)
          B = Emission Allowance Replacement Cost, (Dollars per Ton of SO\\2\\,

          C = Forecast Annual PJM Energy Production, (MWhr)

     1.1  Alternate Dispute Resolution Committee.

     "Alternate Dispute Resolution Committee" shall mean the Committee
established pursuant to Section 5 of this Schedule.

     1.2  MAAC Dispute Resolution Committee.

     "MAAC Dispute Resolution Committee" shall mean the committee established by

     2.1  Common and Uniform Procedures.

     The PJM Dispute Resolution Procedures are intended to establish common and
uniform procedures for resolving disputes arising under the Related PJM
Agreements. To the extent any of the foregoing agreements or the PJM Tariff
contain dispute resolution provisions expressly applicable to disputes arising
thereunder, however, this Agreement shall not supplant such provisions, which
shall apply according to their terms.

     2.2  Interpretation.

     To the extent permitted by applicable law, the PJM Dispute Resolution
Procedures are to be interpreted to effectuate the objectives set forth in
Section 2.1.  To the extent permitted by these PJM Dispute Resolution
Procedures, the Alternate Dispute Resolution Committee shall coordinate with the
MAAC Dispute Resolution Committee, where appropriate, in order to conserve
administrative resources and to avoid duplication of dispute resolution
staffing.

                         3.   NEGOTIATION AND MEDIATION

     3.1  When Required.

     The parties to a dispute shall undertake good-faith negotiations to resolve
any dispute as to a matter governed by one of the Related PJM Agreements.  Each
party to a dispute shall designate an executive with authority to resolve the
matter in dispute to participate in such negotiations.  Any dispute as to a
matter governed by one of the Related PJM Agreements that has not been resolved
through good-faith negotiation shall be subject to non-binding mediation prior
to the initiation of arbitral, regulatory, judicial, or other dispute resolution
proceedings as may be appropriate as provided by these PJM Dispute Resolution
Procedures.

     3.2  Procedures.

          3.2.1   Initiation.

          If a dispute that is subject to the mediation procedures specified
herein has not been resolved through good-faith negotiation, a party to the
dispute shall notify the Alternate Dispute Resolution Committee in writing of
the existence and nature of the dispute prior to commencing any other form of
proceeding for resolution of the dispute.  The Alternate Dispute Resolution
Committee shall have ten calendar days from the date it first receives
notification of the existence of a dispute from any of the parties to the
dispute in which to distribute to the parties a list of mediators.

          3.2.2   Selection of Mediator.

          The Chair of the Alternate Dispute Resolution Committee shall
distribute to the parties by facsimile or other electronic means a list
containing the names of seven mediators with mediation experience, or with
technical or business experience in the electric power industry, or both, as it
shall deem appropriate to the dispute.  The Chair of the Alternate Dispute
Resolution Committee may draw from the lists of mediators maintained by the MAAC
Dispute Resolution Committee, as the Chair shall deem appropriate.  The persons
on the proposed list of mediators shall have no official, financial, or personal
conflict of interest with respect to the issues in controversy, unless the
interest is fully disclosed in writing to all participants in the mediation
process and all such participants waive in writing any objection to the
interest.  The parties shall alternate in striking names from the list with the
last name on the list becoming the mediator.  The determination of which party
shall have the first strike off the list shall be determined by lot.  The
parties shall have ten calendar days to complete the mediator selection process,
unless the time is extended by mutual agreement.

          3.2.3   Advisory Mediator.

          If the Alternate Dispute Resolution Committee deems it appropriate, it
shall distribute two lists, one containing the names of seven mediators with
mediation experience, and one containing the names of seven mediators with
technical or business experience in the electric power industry.  In connection
with circulating the foregoing lists, the Alternate Dispute Resolution Committee
shall specify one of the lists as containing the proposed mediators, and the
other as a list of proposed advisors to assist the mediator in resolving the
dispute.  The parties shall then utilize the alternative strike procedure set
forth above until one name remains on each list, with the last named persons
serving as the mediator and advisor.

          3.2.4     Mediation Process.

          The disputing parties shall attempt in good faith to resolve their
dispute in accordance with procedures and a timetable established by the
mediator.  In furtherance of the mediation efforts, the mediator may:

          (a) Require the parties to meet for face-to-face discussions, with or
without the mediator;

          (b) Act as an intermediary between the disputing parties;

          (c) Require the disputing parties to submit written statements of
issues and positions;

          (d) If requested by the disputing parties at any time in the mediation
process, provide a written recommendation on resolution of the dispute
including, if requested, the assessment by the mediator of the merits of the
principal positions being advanced by each of the disputing parties; and

          (e) Adopt, when appropriate, the Center for Public Resources Model ADR
Procedures for the Meditation of Business Disputes (as revised from time to
time) to the extent such Procedures are not inconsistent with any rule,
standard, or procedure adopted by the Alternate Dispute Resolution Committee or
with any provision of this Agreement.

          3.2.5     Mediator's Assessment.

          (a) If a resolution of the dispute is not reached by the thirtieth day
after the appointment of the mediator or such later date as may be agreed to by
the parties, if not previously requested to do so the mediator shall promptly
provide the disputing parties with a written, confidential, non-binding
recommendation on resolution of the dispute, including the assessment by the
mediator of the merits of the principal positions being advanced by each of the
disputing parties.  The recommendation may incorporate or append, if and as the
mediator may deem appropriate, any recommendations or any assessment of the
positions of the parties by the advisor, if any.  Upon request, the mediator
shall provide any additional recommendations or assessments the mediator shall
deem appropriate.

          (b) At a time and place specified by the mediator after delivery of
the foregoing recommendation, the disputing parties shall meet in a good faith
attempt to resolve the dispute in light of the recommendation of the mediator.
Each disputing party shall be represented at the meeting by a person with
authority to settle the dispute, along with such other persons as each disputing
party shall deem appropriate.  If the disputing parties are unable to resolve
the dispute at or in connection with this meeting, then: (i) any disputing party
may commence such arbitral, judicial, regulatory or other proceedings as may be
appropriate as provided in the PJM Dispute Resolution Procedures; and (ii) the
recommendation of the mediator, and any statements made by any party in the
mediation process, shall have no further force or effect, and shall not be
admissible for any purpose, in any subsequent arbitral, administrative,
judicial, or other proceeding.

     3.3  Costs.

     Except as specified in Section 4.13, the costs of the time, expenses, and
other charges of the mediator and any advisor, and of the mediation process,
shall be borne by the parties to the dispute, with each side in a mediated
matter bearing one-half of such costs, and each party bearing its own costs and
attorney's fees incurred in connection with the mediation.

                               4.   ARBITRATION

     4.1  When Required.

     Any dispute as to a matter: (i) governed by one of the Related PJM
Agreements that has not been resolved through the mediation procedures specified
herein, (ii) involving a claim that one or more of the parties owes or is owed a
sum of money, and (iii) the amount in controversy is less than $1,000,000.00,
shall be subject to binding arbitration in accordance with the procedures
specified herein.  If the parties so agree, any other disputes as to a matter
governed by a Related PJM Agreement may be submitted to binding arbitration in
accordance with the procedures specified herein.

     4.2  Binding Decision.

     Except as specified in Section 4.1, the resolution by arbitration of any
dispute under this Agreement shall not be binding.

     4.3  Initiation.

     A party or parties to a dispute which is subject to the arbitration
procedures specified herein shall send a written demand for arbitration to the
Chair of the Alternate Dispute Resolution Committee with a copy to the other
party or parties to the dispute.  The demand for arbitration shall state each
claim for which arbitration is being demanded, the relief being sought, a brief
summary of the grounds for such relief and the basis for the claim, and shall
identify all other parties to the dispute.

     4.4  Selection of Arbitrator(s).

     The parties to a dispute for which arbitration has been demanded may agree
on any person to serve as a single arbitrator, or shall endeavor in good faith
to agree on a single arbitrator from a list of arbitrators prepared for the
dispute by the Alternate Dispute Resolution Committee and delivered to the
parties by facsimile or other electronic means promptly after receipt by the
Alternate Dispute Resolution Committee of a demand for arbitration.  The
Alternate Dispute Resolution Committee may draw from the lists of arbitrators
maintained by the MAAC Dispute Resolution Committee, as the Alternate Dispute
Resolution Committee deems appropriate.  If the parties are unable to agree on a
single arbitrator by the fourteenth day following delivery of the foregoing list
of arbitrators or such other date as agreed to by the parties, then not later
than the end of the seventh business day thereafter the party or parties
demanding arbitration on the one hand, and the party or parties responding to
the demand for arbitration on the other, shall each designate an arbitrator from
a list for the dispute prepared by the Alternate Dispute Resolution Committee.
The arbitrators so chosen shall then choose a third arbitrator.

     4.5  Procedures.

     The Alternate Dispute Resolution Committee shall compile and make available
to the arbitrator(s) and the parties standard procedures for the arbitration of
disputes, which procedures (i) shall include provision, upon good cause shown,
for intervention or other participation in the proceeding by any party whose
interests may be affected by its outcome, (ii) shall conform to the requirements
specified in these PJM Dispute Resolution Procedures, and (iii) may be modified
or adopted for use in a particular proceeding as the arbitrator(s) deem
appropriate.  To the extent deemed appropriate by the Alternate Dispute
Resolution Committee, the procedures adopted by the Alternate Dispute Resolution
Committee shall be based on the American Arbitration Association Rules, to the
extent such Rules are not inconsistent with any rule, standard or procedure
adopted by the Alternate Dispute Resolution Committee, or with any provision of
these PJM Dispute Resolution Procedures.  Upon selection of the arbitrator(s),
arbitration shall go forward in accordance with applicable procedures.

     4.6  Summary Disposition and Interim Measures.

          4.6.1   Lack of Good Faith Basis.

          The procedures for arbitration of a dispute shall provide a means for
summary disposition of a demand for arbitration, or a response to a demand for
arbitration, that in the reasoned opinion of the arbitrator(s) does not have a
good faith basis in either law or fact.  If the arbitrator(s) determine(s) that
a demand for arbitration or response to a demand for arbitration does not have a
good faith basis in either law or fact, the arbitrator(s) shall have discretion
to award the costs of the time, expenses, and other charges of the arbitrator(s)
to the prevailing party.

          4.6.2   Discovery Limits.

          The procedures for the arbitration of a dispute shall provide a means
for summary disposition without discovery of facts if there is no dispute as to
any material fact, or with such limited discovery as the arbitrator(s) shall
determine is reasonably likely to lead to the prompt resolution of any disputed
issue of material fact.

          4.6.3   Interim Decision.

          The procedures for the arbitration of a dispute shall permit any party
to a dispute to request the arbitrator(s) to render a written interim decision
requiring that any action or decision that is the subject of a dispute not be
put into effect, or imposing such other interim measures as the arbitrator(s)
deem necessary or appropriate, to preserve the rights and obligations secured by
any of the Related PJM Agreements during the pendency of the arbitration
proceeding.  The parties shall be bound by such written decision pending the
outcome of the arbitration proceeding.

     4.7  Discovery of Facts.

          4.7.1   Discovery Procedures.

          The procedures for the arbitration of a dispute shall include adequate
provision for the discovery of relevant facts, including the taking of testimony
under oath, production of documents and other things, and inspection of land and
tangible items.  The nature and extent of such discovery shall be determined as
provided herein and shall take into account (i) the complexity of the dispute,
(ii) the extent to which facts are disputed, and (iii) the amount in
controversy.  The forms and methods for taking such discovery shall be as
described in the Federal Rules of Civil Procedure, except as modified by the
procedures established by the Alternate Dispute Resolution Committee, the
arbitrator(s) or agreement of the parties.

          4.7.2     Procedures Arbitrator.

          The sole arbitrator, or the arbitrator selected by the arbitrators
chosen by the parties, as the case may be (such arbitrator being hereafter
referred to as the "Procedures Arbitrator"), shall be responsible for
establishing the timing, amount, and means of discovery, and for resolving
discovery and other pre-hearing disagreement.  If a dispute involves contested
issues of fact, promptly after the selection of the arbitrator(s) the Procedures
Arbitrator shall convene a meeting of the parties for the purpose of
establishing a schedule and plan of discovery and other pre-hearing actions.

     4.8  Evidentiary Hearing.

     The procedures for the arbitration of a dispute shall provide for an
evidentiary hearing, with provision for the cross-examination of witnesses,
unless all parties consent to the resolution of the matter on the basis of a
written record.  The forms and methods for taking evidence shall be as described
in the Federal Rules of Evidence, except as modified by the procedures
established by the Alternate Dispute Resolution Committee, the arbitrator(s) or
agreement of the parties.  The arbitrator(s) may require such written or other
submissions from the parties as shall be deemed appropriate, including
submission of the direct testimony of witnesses in written form.  The
arbitrator(s) may exclude any evidence that is irrelevant, immaterial, unduly
repetitious or prejudicial, or privileged.  Any party or parties may arrange for
the preparation of a record of the hearing, and shall pay the costs thereof.
Such party or parties shall have no obligation to provide or agree to the
provision of a copy of the record of the hearing to any party that does not pay
an equal share of the cost of the record.  At the request of any party, the
arbitrator(s) shall determine a fair and equitable allocation of the costs of
the preparation of a record between or among the parties to the proceeding
willing to share such costs.

     4.9  Confidentiality.

          4.9.1   Designation.

          Any document or other information obtained in the course of an
arbitral proceeding and not otherwise available to the receiving party,
including any such information contained in documents or other means of
recording information created during the course of the proceeding, may be
designated "Confidential" by the producing party.  The party producing documents
or other information marked "Confidential" shall have twenty days from the
production of such material to submit a request to the Procedures Arbitrator to
establish such requirements for the protection of such documents or other
information designated as "Confidential" as may be reasonable and necessary to
protect the confidentiality and commercial value of such information and the
rights of the parties, which requirements shall be binding on all parties to the
dispute.  Prior to the decision of the Procedures Arbitrator on a request for
confidential treatment, documents or other information designated as
"Confidential" shall not be used by the receiving party or parties, or the
arbitrator(s), or anyone working for or on behalf of any of the foregoing, for
any purpose other than the arbitration proceeding, and shall not be disclosed in
any form to any person not involved in the arbitration proceeding without the
prior written consent of the party producing the information or as permitted by
the Procedures Arbitrator.

          4.9.2   Compulsory Disclosure.

          Any party receiving a request or demand for disclosure, whether by
compulsory process, discovery request, or otherwise, of documents or information
obtained in the course of an arbitration proceeding that have been designated
"Confidential" and that are subject to a non-disclosure requirement under these
PJM Dispute Resolution Procedures or a decision of the Procedures Arbitrator,
shall immediately inform the party from which the information was obtained, and
shall take all reasonable steps, short of incurring sanctions or other
penalties, to afford the person or entity from which the information was
obtained an opportunity to protect the information from disclosure.  Any party
disclosing information in violation of these PJM Dispute Resolution Procedures
or requirements established by the Procedures Arbitrator shall thereby waive any
right to introduce or otherwise use such information in any judicial,
regulatory, or other legal or dispute resolution proceeding, including the
proceeding in which the information was obtained.

          4.9.3   Public Information.

          Nothing in the Related PJM Agreements shall preclude the use of
documents or information properly obtained outside of an arbitral proceeding, or
otherwise public, for any legitimate purpose, notwithstanding that the
information was also obtained in the course of the arbitral proceeding.

     4.10  Timetable.

     Promptly after the selection of the arbitrator(s), the arbitrator(s) shall
set a date for the issuance of the arbitral decision, which shall be not later
than eight months (or such earlier date as may be agreed to by the parties to
the dispute) from the date of the selection of the arbitrator(s), with other
dates, including the dates for an evidentiary hearing or other final submissions
of evidence, set in light of this date.  The date for the evidentiary hearing or
other final submission of evidence shall not be changed absent extraordinary
circumstances.  The arbitrator(s) shall have the power to impose sanctions,
including dismissal of the proceeding for dilatory tactics or undue delay in
completing the arbitral proceedings.

     4.11  Advisory Interpretations.

     Except as to matters subject to decision in the arbitration proceeding, the
arbitrator(s) may request as may be appropriate from any committee or
subcommittee established under a Related PJM Agreement or by the Office of the
Interconnection, an interpretation of any Related PJM Agreements, or of any
standard, requirement, procedure, tariff, Schedule, principle, plan or other
criterion or policy established by any committee or subcommittee.  Except to the
extent that the Office of the Interconnection is itself a party to a dispute,
the arbitrator(s) may request the advice of the Office of the Interconnection
with respect to any matter relating to a responsibility of the Office of the
Interconnection under the Agreement or with respect to any of the Related PJM
Agreements, or to the PJM Manuals.  Any such interpretation or advice shall not
relieve the arbitrator(s) of responsibility for resolving the dispute or
deciding the arbitration proceeding in accordance with the standards specified
herein.

     4.12  Decisions.

     The arbitrator(s) shall issue a written decision, including findings of
fact and the legal basis for the decision.  The arbitral decision shall be based
on (i) the evidence in the record, (ii) the terms of the Related PJM Agreements,
as applicable, (iii) applicable United States federal and state law, including
the Federal Power Act and any applicable FERC regulations and decisions, and
international treaties or agreements as applicable, and (iv) relevant decisions
in previous arbitration proceedings.  The arbitrator(s) shall have no authority
to revise or alter any provision of the Related PJM Agreements.  Any arbitral
decision issued pursuant to these PJM Dispute Resolution Procedures that affects
matters subject to the jurisdiction of FERC under Section 205 of the Federal
Power Act shall be filed with FERC.

     4.13  Costs.

     Unless the arbitrator(s) shall decide otherwise, the costs of the time,
expenses, and other charges of the arbitrator(s) shall be borne by the parties
to the dispute, with each side on an arbitrated issue bearing its pro-rata share
of such costs, and each party to an arbitral proceeding shall bear its own costs
and fees.  The arbitrator(s) may award all or a portion of the costs of the
time, expenses, and other charges of the arbitrator(s), the costs of
arbitration, attorney's fees, and the costs of mediation, if any, to any party
that substantially prevails on an issue determined by the arbitrator(s) to have
been raised without a substantial basis.

     4.14  Enforcement.

     If the decision of the arbitrator(s) is binding, the judgment may be
entered on such arbitral award by any court having jurisdiction thereof;
provided, however, that within one year of the issuance of the arbitral decision
any party affected thereby may request FERC or any other federal, state,
regulatory or judicial authority having jurisdiction to vacate, modify, or take
such other action as may be appropriate with respect to any arbitral decision
that is based upon an error of law, or is contrary to the statutes, rules, or
regulations administered or applied by such authority.  Any party making or
responding to, or intervening in proceedings resulting from, any such request,
shall request the authority to adopt the resolution, if not clearly erroneous,
of any issue of fact expressly or necessarily decided in the arbitral
proceeding, whether or not the party participated in the arbitral proceeding.

     5.1   Membership.

     1.1  Application.

     The obligations of this Schedule apply to each Member that is an Electric
Distributor, whether or not that Member participates in the Electric Distributor
sector on the Members Committee or meets the eligibility requirements for any
other sector of the Members Committee.

     1.2  Obligations.

     Each Electric Distributor shall install or contractually arrange for
underfrequency relays to interrupt at least 30 percent of its peak load with 10
percent of the load interrupted at each of three frequency levels: 59.3 Hz, 58.9
Hz and 58.5 Hz. Upon the request of the Reliability Committee, each Electric
Distributor shall document that it has complied with the requirement for
underfrequency load shedding relays.

                       2.   UNDERFREQUENCY RELAY CHARGES

     If an Electric Distributor is determined to not have the required
underfrequency relays, it shall pay an underfrequency relay charge of:

          Charge = D x R x 365

               where

          D = the amount, in megawatts, the Electric Distributor is deficient;
              and

          R = the daily rate per megawatt, which shall be based on the annual
              carrying charges for a new combustion turbine generator, installed
              and connected to the transmission system, which daily deficiency
              rate as of the Effective Date shall be $58.400/per kilowatt-year
              or $160 per megawatt-day.

               3.   DISTRIBUTION OF UNDERFREQUENCY RELAY CHARGES

     3.1  Share of Charges.

     Each Electric Distributor that has complied with the requirements for
underfrequency relays imposed by this Agreement during a Planning Period,
without incurring an underfrequency relay charge, shall share in any
underfrequency relay charges paid by any other Electric Distributor that has
failed to satisfy said obligation during such Planning Period. Such shares shall
be in proportion to the number of megawatts of a Electric Distributor's load in
the most recently completed month at the time of the peak for the PJM Control
Area during that month rounded to the next higher whole megawatt, as established
initially on the Effective Date and as updated at the beginning of each month
thereafter.

     3.2  Allocation by the Office of the Interconnection.

     In the event all of the Electric Distributors have incurred underfrequency
relay charges during a Planning Period, the underfrequency relay charges shall
be distributed among the Electric Distributors on an equitable basis as
determined by the Office of the Interconnection.

in the case of a Capacity Resource located outside of the PJM Control Area, the
Party shall pay 365 times the daily deficiency rate per megawatt set forth in
Section A of Schedule 11 of the Reliability Assurance Agreement.

          6.1.2     Market-based Offers.

          A Market Seller that is authorized by FERC to sell electric generating

          6.1.3     Availability of Capacity Credits for Sale.

          i)        The Office of the Interconnection shall determine the
                    maximum megawatts of Capacity Credits each Market Seller may

                    of the availability of megawatts of capacity from: (a)

                    during which Buy Bids and Sell Offers are accepted for each
                    market. To enable the Office of the Interconnection to make
                    this determination, no bilateral transactions for capacity
                    or Capacity Credits applicable to the period covered by a
                    PJM Capacity Credit Market will be processed from the
                    beginning of the period for submission of Sell Offers and
                    Buy Bids for that market until completion of the clearing
                    determination for that market. Processing of such bilateral
                    transactions will recommence once all sales for that market
                    are deemed final as specified below .

          iii)      In order for a bilateral transaction for the purchase and
                    sale of a Capacity Credit to be processed by the Office of

                    notify the Office of the Interconnection of the transfer of
                    the Capacity Credit from the seller to the buyer in
                    accordance with procedures established by the Office of the
                    Interconnection.

with the specified deadline for PJM Daily Capacity Credit Markets, a PJM Daily
Capacity Credit Market will be conducted each business day.  Each such PJM Daily
Capacity Credit Market will clear Sell Offers and Buy Bids for Capacity Credits
for use the next business day, and for each of any intervening weekend days or
Holidays.

          6.4.2     PJM Monthly Capacity Credit Markets.

          Following the submission of Sell Offers and Buy Bids in accordance
with the specified deadline for PJM Monthly Capacity Credit Markets, a PJM
Monthly Capacity Credit Market will be conducted.  Each such PJM Monthly
Capacity Credit Market will clear Sell Offers and Buy Bids for Capacity Credits
for use in each of the following twelve months.

     6.5  Market Clearing Procedures.

     i)   For purposes of the rank ordering and market clearing procedures
          described below, the Office of the Interconnection will: (a) evaluate
          all Sell Offers for a Fixed Block at the same price as one Sell Offer
          for a Fixed Block, with the quantity equal to the total quantity of
          the equally-priced Sell Offers; (b) evaluate all Sell Offers for an
          Up-To Block at the same price as one Sell Offer for an Up-to Block,
          with the quantity equal to the total quantity of the equally-priced
          Sell Offers; (c) evaluate all Buy Bids for a Fixed Block at the same
          price as one Buy Bid for a Fixed Block, with the quantity equal to the
          total quantity of the equally-priced Buy Bids; and (d) evaluate all
          Buy Bids for an Up-To Block at the same price as one Buy Bid for an
          Up-to Block, with the quantity equal to the total quantity of the
          equally-priced Buy Bids.

     ii)  The Office of the Interconnection will rank order all Sell Offers and
          Buy Bids by price. Sell Offers will be ranked by lowest price first
          and then ranked in ascending price order. Buy Bids will be ranked by
          highest price first and then ranked in descending price order. Sell
          Offers or Buy Bids for Fixed Blocks will be given priority in the rank
          order relative to Sell Offers or Buy Bids for Up-To Blocks of equal
          price.

     iii) For purposes of the market clearing procedures described below, the
          Office of the Interconnection will not split or pro-rate: (a) a Sell
          Offer for a Fixed Block; (b) a combined set of Sell Offers deemed a
          single Sell Offer for a Fixed Block as specified above; (c) a Buy Bid
          for a Fixed Block; or (d) a combined set of Buy Bids deemed a single
          Buy Bid for a Fixed Block as specified above.

     iv)  The Office of the Interconnection will determine the largest quantity
          of Sell Offers and Buy Bids for which the price of the marginal Sell
          Offer is equal to or less than the price of the marginal Buy Bid. If
          the marginal Sell Offer and the marginal Buy Bid are both for Up-to
          Blocks, or if either or both are for Fixed Blocks that can be
          satisfied without splitting or pro rating any such Fixed Block, the
          market will clear at price specified in the marginal Sell Offer.

     v)   If either the marginal Sell Offer or the marginal Buy Bid (including
          Sell Offers or Buy Bids that are combined as specified above) is for a
          Fixed Block that could not be purchased or sold in full, then that
          Sell Offer or Buy Bid will be removed from the rank order and the
          market clearing price redetermined as specified above. If both the
          marginal Sell Offer and the marginal Buy Bid (including Sell Offers or
          Buy Bids that are combined as specified above) are for Fixed Blocks
          that could not be purchased or sold in full, then both blocks will be
          removed from the rank order and the market clearing price redetermined
          as specified above.

     vi)  If a marginal Sell Offer or Buy Bid is a combination of Sell Offers or
          Buy Bids deemed to be a single Sell Offer or Buy Bid for an Up-To
          Block as specified above, the quantity purchased or sold will be
          allocated among the combined Sell Offers or Buy Bids in proportion to
          the quantities offered in each of the combined Sell Offers or Buy
          Bids.

     vii) If all Sell Offers remaining in the rank order are at prices higher
          than the highest price of any Buy Bid remaining in the rank order, the
          market will be cleared with no transactions, and a market clearing
          price will not be determined.

     6.6  Settlement Procedures.

     Upon determination of the market clearing price as specified above:  (a)
all Sell Offers at a price equal to or less than the market clearing price and
not removed from the rank ordering and for which there is sufficient Buy Bid
demand at or above the market clearing price will be deemed sold at the market
clearing price, and all Buy Bids at a price equal to or greater than the market
clearing price and not removed from the rank ordering and for which there is
sufficient Sell Offer supply at or below the market clearing price will be
deemed satisfied at the market clearing price, with any Up-To Blocks split and
pro-rated as may be appropriate; and (b) the accounts of Market Sellers and
Market Buyers will be credited or debited accordingly.  The foregoing
determinations shall be made, and all sales and purchases shall be deemed final,
as of specified times, as designated by the Office of the Interconnection, on
the day on which each PJM Capacity Market is conducted.

     6.7  Billing.

     The Office of the Interconnection shall prepare a billing statement for
each Market Participant in accordance with the charges and credits specified in
this Schedule, and showing the net amount to be paid or received by each Market
Participant.  Billing statements for PJM Daily Capacity Markets shall be
rendered following the end of each month for Capacity Credits bought and sold in
the month just ended.  Billing statements for PJM Monthly Capacity Credit
Markets shall be rendered following the end of the month for which the Capacity
Credit applies.  Billing statements shall provide sufficient detail, as
specified in the PJM Manuals, to allow verification of the billing amounts and
completion of the Market Participant's internal accounting.  Payment of
statements shall be made in accordance with the Agreement.

     6.8  Time Standard.

     All deadlines for the submission or withdrawal of Sell Offers or Buy Bids,
or for other purposes specified in this Schedule, shall be determined by the
time observed in the Eastern time zone.

                       7.   EFFECTIVE DATE AND TRANSITION

     7.1  Effective Date.

     The Capacity Credit Market Implementation Date shall be October 15, 1998,
or as soon thereafter as the Office of the Interconnection can initiate trading
in the PJM Capacity Credit Market.

     7.2  Transition Provisions.

     To the extent that the Office of the Interconnection is not able to
administer a PJM Capacity Credit Market in accordance with the standards and
procedures specified above at the Capacity Credit Market Implementation Date,
the Office of the Interconnection shall implement the foregoing standards and
procedures if and to the extent practicable.  The Office of the Interconnection
shall thereafter conform to each of the standards and procedures specified above
as soon as practicable.

     7.3  Capacity Credit.

     Prior to the effective date of the provisions for Unforced Capacity under
the Reliability Assurance Agreement, "Capacity Credit" shall mean an entitlement
to a specified number of megawatts of Capacity from a Capacity Resource for the
purpose of satisfying a capacity obligation imposed under the Reliability
Assurance Agreement, and deficiency charges shall be determined in accordance
with the then-current Reliability Assurance Agreement.

     7.4  Mandatory Sell Offers and Buy Bids.

     For the Daily Capacity Credit Markets conducted with respect to the
Operating Days between January 1, 1999 and May 31, 2001, there shall be the
following mandatory Sell Offers and Buy Bids:

     i)   Any Member that owns or has contracted for Capacity Credits or
          Capacity Resources shall be required to make Sell Offers in each Daily
          Capacity Credit Market to the full extent of the megawatts of capacity
          that it has available to sell in excess of its capacity obligations
          imposed under the Reliability Assurance Agreement and other
          contractual obligations to sell capacity, as determined in accordance
          with Section 6.1.3, as of the beginning of the period during which Buy
          Bids and Sell Offers are accepted. To the extent that any such
          megawatts of capacity available to a Member are not contained in such
          Sell Offers, PJM automatically will place for that Member a Sell Offer
          of an Up-To Block for such remaining amounts of capacity at a price of
          zero.

     ii)  A party to the Reliability Assurance Agreement shall be required to
          make Buy Bids in each Daily Capacity Credit Market for the amount of
          capacity that, as of the beginning of the period during which Buy Bids
          and Sell Offers are accepted, it lacks for purposes of meeting its
          capacity obligations imposed under the Reliability Assurance Agreement
          for the Operating Day covered by the Daily Capacity Credit Market. To
          the extent that a party to the Reliability Assurance Agreement does
          not place such Buy Bids, PJM automatically will place for that party a
          Buy Bid of an Up-To Block that, when added to its other Buy Bids,
          would meet its capacity obligations imposed under the Reliability
          Assurance Agreement, at a price equal to the then-current deficiency
          charge under the Reliability Assurance Agreement.

     iii) A party shall have only one position, either excess of or deficient of
          capacity obligations imposed under the Reliability Assurance
          Agreement, as determined by the Office of the Interconnection.
