nevertheless comply with the request, order, or directive of the Company pending
resolution of the dispute under Article 19. The Parties agree to cooperate in
good faith to expedite the resolution of any disputes arising under


                                       17


Sections 6.2 and 6.3.

6.4      If it appears to the Company at any time, in the reasonable exercise of
its judgment in accordance with Good Utility Practice, that the operation of the
Facility or any Interconnection Facility is adversely affecting or may adversely
affect the quality of service rendered by the Company (including transmission or

                    MAINTENANCE NOTIFICATION AND COORDINATION

7.1      The Power Producer shall maintain, at its own expense, the Power
Producer


                                       18


Interconnection Facilities and Protective Apparatus. The Company shall maintain
the Company Interconnection Facilities. The Power Producer shall reimburse the
Company for all actual and verifiable costs and expenses including, but not
limited to, overheads and applicable taxes directly associated with the
maintenance and operation of the Company Interconnection Facilities.

7.2      In accordance with Good Utility Practice, the Company may remove the
Interconnection Facilities from service as necessary, in the reasonable exercise
of the Company's judgment, to perform maintenance or testing or to install or
replace equipment on the Company Interconnection Facilities or the Transmission
System. Unless an Emergency exists or the risk of one in the Company's view is
imminent, the Company shall, if practical, give the Power Producer prior notice
of the removal. The Company shall use due diligence to restore the
Interconnection Facilities to service as promptly as practicable.

7.3      If the Company determines, in its sole judgment, that the Power
Producer is maintaining the Power Producer's Interconnection Facilities and
Protective Apparatus in a manner which may lead to an Emergency condition, the
Power Producer, within thirty (30) days of notification thereof from the
Company, shall take all reasonable steps to conform its maintenance practices to
the requirements of Good Utility Practice and this Agreement.

7.4      At any reasonable time upon advance notice, each Party shall permit the
representatives of the other Party access to the records for its interconnection
facilities in order to examine, inspect and test such records. In the event of
an Emergency, the Power Producer shall ensure that Company representatives have
immediate and unimpeded access to the Power Producer Interconnection Facilities
as necessary to address the Emergency in accordance with Good Utility Practice
working with the Power Producer. The Power Producer hereby grants to the Company


                                       19


the right to enter upon the Power Producer's property for such purposes.

                                    ARTICLE 8
                                REVENUE METERING

8.1      The Company shall utilize Revenue Meters to measure the electrical
energy on an hour-by-hour basis, or such shorter intervals as may be agreed
upon, at the Point of Interconnection in order to determine the transfer of
energy between the Parties.

8.2      All Revenue Meters shall be of advanced meter design that have an
internal recorder and a communications capability that the Company can utilize
to retrieve diagnostic messages, the recorded transfer of energy between the
Parties, and any other information deemed necessary by the Company. The Power
Producer may, at its sole cost and expense, install telemetering or other
communications equipment to retrieve such information as is deemed necessary by
the Power Producer.

8.3      The Parties shall agree that, if the Revenue Meters and analog
equipment and the Point of Interconnection are not at the same location
electrically, the metering data shall be adjusted, or the Revenue Meters shall
be compensated, as the Company shall deem appropriate, to record delivery of
electricity in a manner that accounts for the total (load plus no-load)
electrical energy losses occurring between the metering point and the Point of
Interconnection, both when the Power Producer is delivering energy to the
Company and when the Company is delivering station service energy to the
Facility, or for any other use.

8.4      In the event that the Company's Revenue Meters at any time fail to
register, or should their registration be so erratic so as to be meaningless,
the hourly energy transferred between the


                                       20


Parties shall be determined from the best information available, including, but
not limited to, the Power Producer's meters, operator's logs and real-time
communications data of the meter results.

8.5      If at any time, any Revenue Meters and analog equipment is found to be
inaccurate by a margin greater than that allowed under the applicable criteria,
rules, and standards, the Company shall cause the Revenue Meters and analog
equipment to be made accurate or replaced at the Power Producer's expense. Meter
readings for the period of inaccuracy shall be adjusted insofar as the extent of
the inaccuracy can be reasonably ascertained; provided, however, no adjustment
shall be made for meter readings made prior to the point in time halfway between
the time of the last test that showed the Revenue Meters and analog equipment in
question to be functioning accurately and the time the subsequent inaccuracy is
corrected, except by agreement of the Parties.

8.6      The Company shall read and report Revenue Meter data to the Power
Producer. The Power Producer shall have the right to read the Revenue Meters
upon reasonable notice to the Company.

8.7      The Parties shall each keep and maintain accurate and detailed records
relating to the Revenue Meters for a period of not less than seven (7) years.
Such records shall be made available for inspection by either Party or any
governmental agency having jurisdiction with respect thereto during normal
business hours upon reasonable notice.

8.8      The Company shall at the Power Producer's expense (i) install, own,
maintain, and repair and have the right to change the location of all Revenue
Meters, instrument transformers and appurtenances associated with the Revenue
Meters, and analog equipment (transducers and telemetry) and (ii) install, own,
maintain, and repair all additional or updated metering and


                                       21


associated equipment, as mutually agreed upon by the Parties, needed to update
its metering facilities, in accordance with Good Utility Practice.

8.9      The Company shall, at the Power Producer's expense, test all Revenue
Meters and analog equipment at such time as Company deems reasonably necessary
in accordance with all applicable regulatory requirements or standards. However,
all Revenue Meters and analog equipment shall be tested at least once every two
(2) years.

8.10     Upon written request by the Power Producer, the Company shall test
designated Revenue Meters and analog equipment more frequently than once every
two (2) years. In the event a test requested by the Power Producer establishes
such Revenue Meters to be registering inaccurately by more than one (1%) percent
of full scale, the cost of said test shall be borne by the Company. In all other
instances, the cost of any such test, regardless of which Party requests it or
the results thereof, shall be paid by the Power Producer.

8.11     The Company shall give reasonable notice to the Power Producer of the
time when any Revenue Meters and analog equipment test shall take place, and the
Power Producer may have representatives present at said test. Any Revenue Meters
found to be inaccurate by more than one (1%) percent of full scale or defective
shall be adjusted, repaired or replaced, at the sole cost and expense of the
Power Producer.

8.12     The Company shall install, own, and maintain, at the Power Producer's
expense, equipment, except for associated telephone link(s) which shall be the
sole responsibility of the Power Producer, for real-time communications,
real-time reactive power, hourly MWh information, interval revenue data and such
other information as the Company or the PJM OI may require. The Power Producer
shall install, operate, maintain and repair, at its own expense, an


                                       22


operating telephone link(s) to provide information deemed necessary by the
Company or the PJM OI, or as reasonably deemed necessary by the Company, to
integrate operation of the Facility with the Transmission System.

                                    ARTICLE 9
                             LAND RIGHTS AND ACCESS

9.1      The Power Producer hereby grants, or confirms its prior grant to the
Company, for nominal consideration, all necessary rights of way, easements, and
licenses as the Company may require to install, operate, maintain, replace and
remove the Company's metering equipment and other Company Interconnection
Facilities, including adequate and continuing access rights to the Power
Producer's property for any purpose reasonably related to this Agreement. The
Power Producer hereby agrees to execute such grants, deeds, licenses,
instruments and other documents as the Company may require to enable it to
record such rights of way, easements and licenses.

                            LIABILITY AND DEDICATION

12.1     Nothing in this Agreement shall be construed to create any duty to,
standard of care with respect to, or any liability to any person not a Party to
this Agreement.

12.2     Neither the Company nor the Power Producer, nor their respective
officers, directors, partners, agents, employees, or Affiliates, shall be liable

                                 INDEMNIFICATION

13.1     The Power Producer shall indemnify, hold harmless and defend the
Company, and its Affiliates, as the case may be, and their respective officers,
directors, employees, agents, partners, subcontractors, invitees and successors,
from and against any and all claims, liabilities, costs,


                                       28


damages, losses, and expenses (including, without limitation, reasonable
attorney and expert fees, and disbursements incurred by the Company in any
action or proceeding between the Company and a third party, the Power Producer,
or any other party) for damage to property, injury to or death of any persons,
including the Company's employees or any third parties (collectively, "Company's
Damages"), to the extent caused wholly or in part by any act and/or omission,
negligent or otherwise, relating to the design, construction, ownership,
operation, or maintenance of the Facility, Power Producer Interconnection
Facilities and Protective Apparatus used in connection with this Agreement and
provided, however; that Power Producer, or its respective Affiliates, and
successors, and their respective officers, agents, directors, partners or
employees shall not be liable to the Company, its Affiliates, and successors,
and their respective agents, officers, directors, partners or employees for
incidental, special indirect or consequential damages of any nature connected
with or resulting from performance or non-performance of this Agreement. Company
hereto will furnish the Power Producer with written notification after the
Company becomes aware of any event or circumstances, or the threat thereof (but
in no event later than ten (10) days prior to the time any response is required
by law), which might give rise to such indemnification. At the Company's
request, the Power Producer shall defend (with counsel reasonably acceptable to
the Company) any suit asserting a claim covered by this indemnity and shall pay
all costs and expenses (including the cost of investigation and attorney's fees
and expenses) that may be incurred in enforcing this indemnity. The Company may,
at its own expense, retain separate counsel and participate in the defense of
any such suit or action.

13.2     The indemnity in Section 13.1 shall apply to all claims against the
Company including, but not limited to, all claims made or threatened by, or in
the name of or on behalf of the


                                       29


Company's employees for personal injuries (including death) which arise in the
course of their employment; provided, however that said indemnity shall not
apply to any liability ultimately determined to be based upon the negligence of
the Company. The Power Producer hereby waives any defense it may otherwise have
under applicable workers' compensation laws.

13.3     In addition to Sections 13.1 and 13.2 above, the Power Producer shall
indemnify, hold harmless and defend the Company from and against any and all
liability, loss, cost, damage and expense, associated with any and all Federal,
State and/or local tax liability, arising out of, resulting from or in
connection with Power Producer's payment (or failure to pay) to the Company, of
the costs associated with the purchase and installation of any portion of the
Company's Interconnection Facilities, Protective Apparatus and/or any and all
associated and/or related structures, equipment, facilities and devices in
performance of, pursuant to or in connection with this Agreement, including any
expense resulting from such payment being deemed to be a Contribution In Aid of
Construction ("CIAC") pursuant to U.S. Internal Revenue Service Notices 88-129
and 90-60 (and any future applicable U.S. Internal Revenue Service notices),
which Notices are incorporated by reference herein. The foregoing
indemnification obligations of the Power Producer shall not, however, apply with
respect to any of the equipment or facilities referred to immediately above
which the Company has included in its rate base and is collecting revenues from
its customers. The Parties expressly acknowledge and agree that Sections 13.1,
13.2 and 13.3 shall survive the termination or expiration of this Agreement.

13.4     Power Producer shall provide the Company with an Independent
Engineering Certification (i.e., the professional engineer's seal shall be
affixed), as specified in IRS Notice 88-129, attesting that the anticipated
power flows through the Interconnection Facilities to the Power


                                       30


Producer for the first ten years commencing with the taxable year in which the
Interconnection Facilities are placed in service, (or alternatively, for the
first nine years ignoring the year such facilities are placed in service) will
comprise no more than 5% of the projected total power flows over the
Interconnection Facilities. This engineering certification will be provided to
the Company within forty-five days of the execution of this Agreement. In the
event this certification is not provided to the Company, the Company retains the
right to include the tax gross-up in the final billing for the actual costs of
the Interconnection Facilities. In the event the 5% test, as specified in IRS
Notice 88-129, is exceeded during any measuring period, described in section
4(A) of Notice 88-129 (a "disqualifying event"), Power Producer agrees to make
the Company whole for any increase in the Company's Federal and State income tax
liabilities arising from this condition. This increase in the Company's Federal
and State income tax liabilities will be determined in accordance with the
requirements of IRS Notice 90-60, as amended or supplemented.

disposition of the Facility or any substantial portion thereof by the Power
Producer, or upon termination of the Agreement, or termination of any operation
at the Facility, the Power Producer hereby agrees to indemnify and hold harmless
the Company for any and all costs, expenses, liabilities and damages (including
reasonable attorneys' fees) for which the Company may be obligated in order to
comply with any applicable requirements of the federal, state, or local

                  Administration building
                  Workshop and store


The turbine generators will be nominally rated at 288MVA, 0.9 power factor
lagging and can operate at approximately 0.95 power factor leading (measured at
the generator), 16kV at 60Hz., 0.53 short circuit ratio, and 60 psi rated
hydrogen pressure.

The Facility will be capable of operation with a voltage range of +/- 5% on the
230kV system.

The Facility will be supplied with three generator start up transformers rated
at 300MVA, 16% impedance, with off line tap changing, and two auxiliary
transformers.

Interconnection with the GPU system will be via a 230kV single bus, single
breaker out door substation with two transmission lines.

The Facility has no black start capability.

                  with industry practice and as may be necessary for the Company
                  to comply with its applicable requirements. The Company will
                  advise the Power Producer of such requirements as in effect
                  from time to time. The Power Producer shall make such records
                  available to the Company for inspection and copying from time
                  to time as the Company may reasonably request.


IV.      NORMAL OPERATION REQUIREMENTS

         A.       Generator Governor Control

                  For any Facility engaged in parallel operation with the
                  Company, the Facility shall:

                  1.       Operate on automatic governor control, except for the
                           periods immediately before generating equipment is
                           being removed from service and immediately after it
                           has been placed in service, and

                  2.       Minimize governor outages during periods of
                           operation.

                  1.       The Power Producer shall obtain the Transmission
                           Operator's prior approval (i.e., at least 30
                           minutes), except that equipment may be disconnected
                           from the system without Company approval to prevent
                           injury to personnel or equipment damage. If for any
                           reason the disconnection occurs without prior Company
                           approval, the Power Producer shall immediately notify
                           the Transmission Operator as to the energy reduction
                           and the expected return time.

                  2.       In order to support the Transmission Operator's
                           responsibility to plan and operate the normal and
                           emergency operations of the transmission system, the
                           Power Producer shall keep the Transmission Operator
                           informed at all times of the Facility's availability
                           or any change(s) to its status.

                                       C5


         C.       Voltage and Reactive Control Procedures

                  1.       The Power Producer shall operate the Facility with
                           automatic voltage regulation equipment in service at
                           all times, except for outages of the regulator for
                           maintenance or equipment failure. Such operation will
                           normally involve a prescribed voltage limited to +/-
                           1% of schedule. The Power Producer, at the option of
                           the Company, shall operate the Facility either (i)
                           according to a predefined voltage schedule provided
                           by the Company or (ii) according to a reactive power
                           schedule as provided by the Company, consistent with
                           the Facility's generation capability and the
                           Company's electrical system. From time to time, the
                           Company may request alternate schedules consistent
                           with the Facility's generation capability and the
                           Company's electrical system.

                  2.       The Power Producer shall notify the Transmission
                           Operator prior to performing all voltage regulator
                           maintenance. The Power Producer shall notify the
                           Company of the outage with as much lead time as
                           possible. The Power Producer shall minimize the
                           duration of regulator equipment outages. The Power
                           Producer shall notify the Transmission Operator at
                           least 30 minutes prior to removing the voltage
                           regulator from service, or returning the voltage
                           regulator to service.

                  3.       The Power Producer may be requested by the Company to
                           deviate from prescribed voltage or reactive power
                           schedules if, in the Company's sole judgment,
                           conditions warrant such changes including, without
                           limitation, operating the Facility in the leading,
                           lagging, or unity power factor mode, but within the
                           capability of the machine.

                  4.       The Power Producer shall operate automatic voltage
                           regulation to a tolerance of +/- 1% of scheduled
                           voltage, except for regulator maintenance outages or
                           equipment failures, or conditions prevailing on the
                           system and/or the Power System which necessitate
                           other voltage levels.

                  5.       The Power Producer shall provide manual voltage
                           regulation to maintain the prescribed voltage
                           schedule or reactive power schedule during voltage
                           regulator equipment outages.

                  6.       Momentary voltage fluctuations shall be permitted,
                           provided that they neither disturb service provided
                           by the Company or the Power Producer on their
                           respective systems nor hinder the Company from
                           maintaining proper voltage conditions on their
                           respective systems.

         D.       Maintenance Scheduling

                  1.       The Power Producer shall provide the Company with at
                           least thirty (30) days prior written notice of its
                           intent to take a Generator Planned Outage


                                       C6


                           or Generator Maintenance Outage of the Facility,
                           including turbine, generator, and boiler overhauls or
                           inspections, testing, and nuclear refueling.

                  2.       The Power Producer shall provide the Company with at
                           least thirty (30) days prior written notice of its
                           intent to test Protective Apparatus associated with
                           Power Producer Interconnection Facilities, including
                           circuit breakers, relays and auxiliary equipment.
                           Company personnel may observe such testing.

                  3.       The Power Producer shall notify the Transmission
                           Operator of its intent to remove electrical equipment
                           from service by 10:00 a.m. five (5) working days
                           prior to, and again 30 minutes before the Generator
                           Planned Outage or Generator Maintenance Outage
                           begins. The Transmission Operator may request the
                           Power Producer to delay or reschedule the Generator
                           Planned Outage or Generator Maintenance Outage if
                           system reliability conditions warrant.

                  To the extent practical, the Company shall provide to the
                  Power Producer not less than one week advance notice of its
                  intention to perform planned maintenance on its facilities
                  that may affect the Facility's operations. The Company shall
                  notify the Power Producer when any changes occur.

         E.       Power Producer Generator Forced Outages

                  The Power Producer may remove any of its equipment from
                  service without prior notification to the Transmission
                  Operator due to a Generator Forced Outage. However, if the
                  Power Producer has advance knowledge of a Generator Forced
                  Outage, the Power Producer shall notify the Transmission
                  Operator with as much lead time as practical. For reliability
                  reasons the Power Producer shall notify the Transmission
                  Operator as soon as reasonably possible of the following:

                  -        the starting time of the Generator Forced Outage
                  -        the energy reduction resulting (or expected to
                           result) from the Generator Forced Outage
                  -        the estimated time the equipment incurring the
                           Generator Forced Outage is expected to return to
                           service
                  -        the time the Power Producer equipment is actually
                           returned to service.

         F.       Facility Equipment and Contract Data

                  In order to ensure that all Company personnel responsible for
                  the design and operation of the Company's system affected by
                  the Facility are familiar with its equipment configurations,
                  capabilities and operating parameters, the Company may from
                  time to time request, and the Power Producer shall provide in
                  a timely manner to the Company, detailed information about the
                  type, nature, and operating characteristics of the Facility

                                       C7


V.       EMERGENCY OPERATION REQUIREMENTS

         The Power Producer and Company shall maintain communications and
         contact during all Company or PJM emergency operations.

         A.       System Emergency Conditions

                  During an Emergency, as determined/declared by the Company or
                  the PJM OI, the Power Producer shall respond as promptly as
                  possible to all directives from the Transmission Operator with
                  respect to all matters affecting the operation of the Facility
                  including, without limitation, the following:

                  a.       Thermal overload of electrical circuits (actual or
                           contingency)

                  b.       High or low voltage conditions (actual or
                           contingency)

                  The Transmission Operator may also direct the Power Producer
                  to (i) adjust (increase or decrease) the Facility energy
                  and/or reactive output (ii) connect or disconnect the Facility
                  from the Company's electrical system and/or (iii) deviate from
                  the prescribed voltage or reactive schedules. If safety or
                  system reliability conditions warrant, the Transmission
                  Operator may isolate the Facility from the Company's
                  electrical system without prior notice to the Power Producer
                  or upon such notice as is possible under the circumstances.
                  The Transmission Operator shall advise the Power Producer as
                  soon as possible of any forced outages of the Company's
                  electrical system which affect the Facility's operations.

                  When the Transmission Operator has determined that the
                  emergency conditions have been alleviated, he/she shall inform
                  the Power Producer and allow the Facility to return to normal
                  operations consistent with Good Utility Practice.

                  In order to safely and rapidly restore the Transmission System
                  following an outage of any or all of that system, a Facility
                  that has been isolated from the Company's electrical system
                  shall be allowed to reconnect only under the direction of the
                  Transmission Operator. In all cases, the Facility shall be
                  made ready to return to service and provide energy to the
                  Company as soon as possible.

                  Unless the Company requests a manual adjustment, the Power
                  Producer shall maintain the Facility automatic voltage
                  regulator in service during an Emergency.

                  The Power Producer shall participate in any voltage reduction
                  declared by the Company at any time, and operate the Facility
                  at the voltage level then requested by the Transmission
                  Operator.

                          Interconnection Requirements


                                       D1


                                  GPU ENERGY'S

                          SYSTEM PROTECTION AND CONTROL

                          INTERCONNECTION REQUIREMENTS

                           Revised: November 17, 1997


A.       Definitions

         GPU Energy - The trade name used individually and collectively by the
         three operating electric utilities in the GPU System (i.e., Jersey
         Central Power and Light Company, Metropolitan Edison Company, and
         Pennsylvania Electric Company).

         GPU System - The transmission and distribution facilities owned by GPU
         Energy.

         Generation Facility - A facility for generating electricity which is
         connected to the GPU system.

         Generation - The electrical energy being produced by: rotating
         generators driven by steam turbines, internal combustion engines,
         hydraulic turbines, windmills, etc; fuel cells, photovoltaic or battery
         arrays with a DC or AC inverter; or any other electric generating
         device.

         Power Producer - The owner or operator of the Generation Facility.

B.       Objectives

         This document was prepared to assist GPU Energy engineers and Power
         Producers when planning protection and control requirements for
         interconnection between GPU Energy and the Generation Facility.

         To ensure all proposed installations are handled uniformly and to
         minimize the possibility of misinterpreting GPU Energy / /s
         requirements, this document outlines the minimum protection
         requirements for the safe and effective operation of this
         interconnection, and provides technical and administrative guidelines.

C.       General Policy

         The minimum protection requirements stated in this document are
         intended to achieve the following goals:

         -        Insure the safety of the general public and GPU Energy
                  personnel.

         -        Minimize the possible damage to the property of the general
                  public, GPU Energy , GPU Energy customers, and neighboring
                  utility systems.

         -        Minimize adverse conditions on the GPU System.

         -        Permit the Power Producer to operate its generating equipment
                  in parallel with the GPU System in a safe and reliable manner.


                                       D2


         In order to achieve these goals, certain protective devices (relays,
         circuit breakers, etc.) must be installed to promptly disconnect the
         Generating Facilities from the GPU System whenever a fault or
         abnormality occurs. The determination of what type of protective
         devices are required depends primarily on three (3) major factors:

         1)       The type and size of the Generation Facility.

         2)       The location of the Generation Facility on the GPU System.

         3)       The manner in which the installation will operate.

         In addition to the protective devices, certain modifications and/or
         additions may be required to be made to the GPU System due to the
         addition and/or modification of the Generation Facility. Each request
         will be handled individually, and the final determination of the
         protective devices, modifications, and/or additions required will be
         made by GPU Energy. Any modifications to the GPU Energy distribution or
         transmission systems necessitated by these changes to the Generation
         Facility will be specified, purchased, and installed by GPU Energy at
         the expense of the Power Producer.

         GPU Energy will work with the Power Producer to achieve an installation
         which meets the requirements of both the Power Producer and GPU Energy.

         GPU Energy cannot assume any responsibility for protection of the
         Generation Facility's generating equipment, or any portion of the
         Generation Facility's equipment. The Power Producer is solely
         responsible for protecting its equipment in such a manner that faults,
         imbalances or other disturbances on the GPU System do not cause damage
         to the Generation Facility's equipment.

         It is the responsibility of the Power Producer to comply with all
         applicable Federal, State, and Local Regulatory Agencies and all
         electrical and safety codes. Further, the Power Producer may be
         required, in GPU Energy?s sole and exclusive judgement, to retrofit its
         interconnection protection systems due to obsolescence, operational
         problems, enhancements in microprocessor/solid state technology leading
         to improved sensitivity, modifications to the GPU system or the
         Generation Facility, and in accordance with the most recently published
         industry standards and practices.

         Any interconnection of a Generation Facility to the GPU System must not
         impair the quality and quantity of transmission or distribution service
         available to its customers, create reliability problems, or interfere
         with the operation and economic dispatch of power sources in which GPU
         Energy has entitlement or with GPU Energy?s ability to carry out its
         obligations under pre-existing agreements.

         A Generation Facility will not be permitted to be connected to the GPU
         Energy low voltage (< 1 kV) looped network system.

         A GPU Energy controlled disconnecting device is required on the GPU
         Energy side of all Generation Facility interties.

         A Generation Facility's disconnecting device used to isolate the
         facility's generation from the GPU System shall be blocked from closing
         in on a de-energized utility circuit.

         The Power Producer is responsible for properly synchronizing its
         generation with the GPU System.

D.       Review Process

         In order to process all Power Producer requests in an efficient and
         con-sistent manner, the following Review Process for Protection
         Requirements must be followed.

         1.       Preliminary Protection Requirements Review

                  The GPU Energy System Relay and Control Engineering Department
                  will have primary responsibility for


                                       D3


                  the review and comment of all required protection design and
                  associated settings.

                  The following information shall be supplied to GPU Energy :

                  a)       Detailed One-Line Diagram of entire Generation
                           Facility system.

                  b)       A potential schematic of Generation Facility.

                  c)       A current schematic of Generation Facility.

                  d)       A control schematic of Generation Facility.

                  e)       A connection diagram indicating all external
                           connections to individual components of the
                           protective scheme.

                  f)       A three-line diagram of Generation Facility.

                  g)       Instruction manuals for all protective equipment.
                           Component specifications and internal wiring diagrams
                           shall be included if not provided in manuals.

                  h)       All protective equipment ratings.

                           circuit breakers, current transformers, voltage
                           transformers, and any other major equipment or
                           special items.

                  k)       Specific setting information on all the Generation
                           Facility's protective relays associated with the
                           generator protection and generator step-up
                           transformer protection or auxiliary transformer
                           protection.

         One set of all the above information is required. GPU Energy may in its
         discretion require that meeting(s) be held between GPU System Relay and
         Control Engineering personnel and the Power Producer's Consulting
         Engineer, Contractor, etc. during this process.


         Upon completion of the Preliminary Protection Requirements Review
         process, the Power Producer's representative will be notified of any
         modifications and/or additions, required to the GPU System or to the
         Generation Facility. The Power Producer's representative shall also be
         notified by GPU Energy that the Preliminary Protection Requirements
         Review process is to be accomplished in a timely manner and that it
         must represent an as accurate as possible determination of protection
         requirements, however the Power Producer's representative shall be
         notified that the information submitted will be subject to change
         modification and/or addition by GPU Energy, in its sole and exclusive
         discretion.

2.       Final Protection Requirements Review

         The Final Protection Requirements Review process will proceed in the
         same manner as the Preliminary Protection Requirements Review process
         outlined in Section D-1 above.

         The information identified in Section D-1, including any modifications
         and/or additions made by GPU Energy during the Preliminary Protection
         Requirements Review process, will be required in triplicate. The
         Instruction manuals for all protective equipment required pursuant to
         Section D.1.(g) must contain at least one vendor original copy. All
         information supplied for this review process shall be Final\As-Built
         submittal information.

         Upon GPU Energy's completion of its initial review of the Power
         Producer's final submittal, the Power Producer's representative will be
         notified of any final modifications and/or additions required to the
         GPU System or to the Generation Facility. Upon the Generation
         Facility's satisfactory completion, as determined by GPU Energy in its
         sole and exclusive judgement, of any required final modifications
         and/or additions, GPU Energy will notify the Power Producer's
         representative that the Final Protection Requirements Review process
         has been completed.

E.       Design Consideration

         1.       Automatic Reclosing

                  The need for automatic reclosing modifications is directed
                  towards protection of the GPU System and the equipment of GPU
                  Energy customers from potential damage. It is the Power
                  Producer's responsibility to evaluate the potential effect of
                  GPU Energy's reclosing practices on its generator and to
                  provide suitable protection.

                  GPU Energy normally provides automatic multiple shot reclosing
                  with no intentional time delay on the first shot on all
                  distribution line circuit breakers. Additionally, automatic
                  sectionalizing for faults is provided on the distribution
                  system with electronic and hydraulic reclosers that reclose in
                  approximately 2 seconds following a trip operation. To protect
                  both GPU Energy and GPU Energy customers' equipment from
                  possible damage due to out-of-phase reclosing, the substation
                  distribution line circuit breaker and the line reclosers may
                  have to be modified, at the expense of the Power Producer,
                  with voltage check relays unless the size and characteristics
                  of the generator indicate that immediate reclosing would not
                  be hazardous to the GPU System. These relays will block
                  reclosing until the parallel generation on a line or line
                  section is de-energized.

                  Lines operated at 34.5 kV Delta and above also utilize
                  multi-shot automatic reclosing with the first shot delayed
                  approximately 20 cycles. Reclosing logic for these lines must
                  be modified, at the expense of the Power Producer, to include
                  synchronism checking.

         2.       Protection Requirements

                  Typical protection is illustrated in Appendix A Figures 1 and
                  2 inclusive.

                  The design of the Isolation and Fault Protection shall be
                  based upon a single failure philosophy, i.e., the failure of
                  any single component shall not render the protection
                  inoperative.

                  Isolation and fault protective relays shall be purchased,
                  installed and owned by the Power Producer. The required fault
                  and isolation protection shall be utility grade and conform to
                  the most recent ANSI Standard C37.90. Only solid
                  state/microprocessor based relay models are acceptable.

                  Isolation Protection

                  All relay settings associated with the Isolation Protection
                  shall be specified by GPU Energy.

                  GPU Energy shall have exclusive control and access to the
                  Isolation Protection.

                  a)       Undervoltage (27) with Time Delay (62). Relay to be
                           set at approximately 90% of nominal voltage (108
                           secondary volts on a 120 volt base). Time delay to be
                           set at approximately 2.0 seconds in order to provide
                           coordination with motor starting and system faults.

                  b)       Overvoltage (59) with Time Delay (62). Relay to be
                           set at approximately 110% of nominal voltage (132
                           secondary volts on a 120 volt base). Time delay to be
                           set at approximately 2.0 seconds to over-ride relay
                           response to transients and external fault clearing
                           which may cause nuisance operations.

                  c)       Overfrequency (81O). Relay to be set at 60.5 Hertz
                           with no intentional time delay in its operation.


                                       D5


                  d)       Underfrequency (81U) with Time Delay (62). Relay to
                           be set at 57.5 Hertz with a 5.0 second time delay.
                           This setting is necessary in order to coordinate with
                           GPU Energy 's system loadshedding underfrequency
                           relaying. GPU Energy , as a member of the
                           Pennsylvania- New Jersey-Maryland Interconnection
                           (PJM) agreement, has agreed to trip generators
                           connected to its system at a frequency of 57.5 Hertz
                           after a delay of 5.0 seconds. Therefore, the Power
                           Producer must also comply with this agreement. The
                           Power Producer is responsible to insure that setting
                           is compatible with all equipment purchased, installed
                           and operated at the Generation Facility.

                  Fault Protection

                  Generation Facility's fault protection shall coordinate with
                  GPU System protective devices for faults. All fault protection
                  settings are to be specified by the Power Producer and
                  approved by GPU Energy for coordination purposes only.

                  e)       Out-of-Step Relaying (21 ZOS). Relays maybe required
                           to isolate the generator from the GPU System during
                           unstable conditions. The need for out-of-step
                           relaying will be based on the results of stability
                           studies. The Power Producer will be responsible for
                           providing the appropriate relay and settings.

                  f)       Synchronism Check (25). A synchronism check relay
                           will be required on all breakers that may be used to
                           synchronize the generator to the system. The
                           synchronism check relay shall be capable of being set
                           for an angular difference of 10-60 degrees and have
                           an internal timer function allowing a time delay
                           setting between 0.5-5 seconds. The relay chosen must
                           also have an optional hot-bus dead-line; dead-bus
                           hot-line accessory.

                  g)       Non-directional phase overcurrent (50/51),
                           non-directional ground overcurrent (50/51G), and
                           non-directional neutral overcurrent (51N) relays.
                           Where high-side of transformer (GPU System side) is
                           connected to the GPU System via a device other than a
                           fuse, the above mentioned protective relays are
                           required. Current transformers for the 50/51 and
                           50/51G relays shall be located on the high-side of
                           the transformers protective device (breaker, circuit
                           switcher, etc.) If high-side grounding of the
                           transformer is provided, the 51N relay shall be
                           connected to a current transformer installed in the
                           neutral connection of the transformer.

                  h)       Voltage controlled time overcurrent relays (51V). In
                           applications where the Generation Facility is
                           interconnected to GPU Energy's distribution system
                           (34.5 kV Wye and below), voltage - controlled time
                           overcurrent relays must be provided. These relays
                           shall be connected to current transformers located on
                           the generator or its associated breaker. These relays
                           shall receive potential from the generator voltage
                           transformers.

                  i)       System backup impedance (21) relay(s). In
                           applications where the Generation Facility is
                           interconnected to GPU Energy's transmission system
                           (34.5 kV Delta and above), an impedance relay must be
                           provided as a backup function to clear faults on the
                           GPU Energy System. This relay(s) shall be connected
                           to current transformers located on the generator or
                           its associated breaker. These relays shall receive
                           potential from the generator voltage transformers. An
                           external timer (0.1 - 5.0 sec) must be provided if
                           not provided internal to the impedance relay design.
                           Time delay will be typically set between 1.0 and 2.0
                           seconds.

F.       CONTROL SYSTEMS

         The Power Producer has the option to use either an AC or DC control
         system, as described below.

         1.       AC SYSTEM


                                       D6


                  The AC control system supply must use 60 Hz power derived from
                  the GPU Energy line. The system must be designed to be
                  fail-safe and the failure of any single component must result
                  in a trip of the generator breaker.

                  NOTE: In AC powered schemes, the generator breaker will
                  probably be a contactor. In such cases, a latching contactor
                  is not acceptable. The AC System shall use continuously
                  energized auxiliary relays with contacts arranged to trip the
                  generator circuit breaker whenever the relays drop out. If a
                  molded case circuit breaker (or equal) is used, it must be
                  equipped with an undervoltage trip option.

                  All installations must isolate (trip) the generator in such a
                  manner that:

                                   a manual operation


                                           or

                  a time-delayed automatic synchro-check or voltage

                  check supervised operation

                  is required to close the generator or point-of-contact breaker
                  (contactor) after the GPU Energy source has returned to
                  normal.

                  Under no circumstances is the generator contactor (breaker) to
                  close immediately upon restoration of the GPU Energy source.

                  A white lamp should be provided to monitor the AC source and
                  shall have a nameplate.

         2.       DC SYSTEM

                  This system must use a battery of 48 or 125 VDC to supply
                  tripping energy to the generator circuit breaker.

                  All such installations must isolate (trip) the generator in
                  such a manner that:

                                   a manual operation

                                           or

                  a time-delayed automatic synchro-check or voltage

                  check supervised operation

                  is required to close the generator or point-of-contact breaker
                  (contactor) after the GPU Energy source has returned to
                  normal.

                  Under no circumstances is the generator contactor (breaker) to
                  close immediately upon restoration of the GPU Energy source.

                  An amber or yellow lamp shall provided to monitor the DC
                  source and shall have a nameplate.

G.       TARGETS

         All protective relays shall be equipped with targets that indicate
         operation. These targets are to be arranged in the


                                       D7


         control circuit to operate only when the associated relays trip the
         generator or point-of-contact circuit breaker.

H.       REMOTE TERMINAL UNIT (RTU)

         For all Generation Facility installations, a Remote Terminal Unit (RTU)
         will be purchased and installed by GPU Energy at the expense of the
         Power Producer. This RTU will utilize the CDC II protocol and provide
         the necessary point counts required by the Energy Management System
         (EMS) of GPU Energy to operate and monitor the generation and
         interconnection facilites at the Generation Facility site. Point count
         will include, but not be limited to, analog, MWH, control, and status.

         The Power Producer will provide an indoor weather controlled location
         to mount an RTU and supply a four (4) wire data telephone circuit in
         order for the RTU to communicate with the GPU Energy EMS. Furthermore,
         a telephone and telephone circuit must be provided in the location of
         the RTU in order that GPU Energy personnel may communicate with the
         distribution or transmission operator for installation and maintenance
         purposes.

         If necessary, provisions shall be made at the bottom of each enclosure
         to allow all cables to be wired to the RTU. The Power Producer must
         also supply the power necessary for the RTU. The supply power can be,
         but not limited to, 125 VDC, 120 VAC, and 48 VDC.

I.       GROUNDING

         Neutral and ground are not to be confused. All current and potential
         neutrals are to be isolated from all other circuits. Each neutral is to
         be grounded at one point only. The preferred grounding location will be
         at the protective relay cabinet, on the internal side of the States
         links.

J.       WIRING

         All wiring must agree exactly with schematics and wiring drawings.

         All wires must be anchored to the cabinet or bundled when running
         between devices. Bundling is permitted but all wiring must be
         traceable. Wiring must be installed so that it can be visually traced
         and checked. Use of conduit, or equal, wire trough is generally
         acceptable but must be verified with GPU Energy.

         Wiring shall be installed so as to avoid damage to the cable and its
         insulation. Movement of the hinged panel shall not damage the cable or
         its insulation or cause stress to the termination points on the panel
         or on the door.

         Wiring and device location shall not prevent the removal of any
         equipment, block access to equipment for inspection and maintenance,
         nor block spare space in the cabinet.

         All equipment shall be mounted and wired in such a manner that no
         energized terminals or connections are exposed or accessible to
         personnel with the hinged relay panel in a closed position.

         Any protective relay not equipped with internal isolation device must
         be connected through an external test device (i.e., ABB FT-1 or sliding
         link terminal blocks as determined and approved by GPU Energy .)

         All incoming and outgoing cables/conductors will terminate on sliding
         link terminal blocks located in the protective relay cabinet.



                                       D8


         Terminal blocks shall be the States Company Type NT or equivalent.

         The incoming side shall have one (1) nut, for mounting incoming cables.

         The internal panel side shall have double nuts for mounting of internal
         wires and marker tags. Marker tags should carry wire or cable conductor
         identification.

         Terminal blocks shall be mounted such that the connections and lines
         are accessible and not blocked by projecting equipment.

         Terminal blocks shall be mounted a minimum of 6" from side walls and
         adjacent equipment and a minimum of 4" above the bottom of the housing.

         Terminal blocks shall be mounted such that the sliding link:

                  Falls closed when loosened, if mounted in horizontal rows;

                  Moves toward the front of the cabinet when opened, if mounted
                  in vertical rows on side panels;

                  Moves away from the panel centerline when opened, if mounted
                  on the rear panel.

         There shall be a minimum of 10% or 2, whichever is greater, spare
         terminals included in the cabinet for modifications.

         Pressure type connections with insulated sleeves shall be used.

         Ring tongue lugs which completely encircle the screw or the stud shall
         be used.

         The crimping tool must be one approved by the Manufacturer for use on
         the connector.

         No soldered terminals or connections shall be used.

         THIS AGREEMENT ("Installation Agreement"), entered into the ______ day
of ____________, 19_____, between Metropolitan Edison Company d/b/a GPU Energy,
(hereinafter referred to as the "Company") and AES Ironwood, L.L.C.,
(hereinafter referred to as "Power Producer"), collectively "Parties".

                                    RECITALS

         WHEREAS, Power Producer desires to build the Ironwood power plant and
interconnect with the Transmission System; and

         WHEREAS, the Company is willing to design, furnish, install and own
certain facilities required to interconnect Power Producer's Facility with the
Transmission System, as more fully defined and described in the Generation
Facility Transmission Interconnection Agreement between the Parties ("Company
Interconnection Facilities").

         WHEREAS, Power Producer has placed a high priority on the Schedule of
Work and desires that the Company accept Bonus/Liquidated Damages provisions
relating to this Installation Agreement.

         WHEREAS, the Company is willing to accept Bonus/Liquidated Damages
provisions relating to this Installation Agreement.

         NOW, THEREFORE, in consideration of the mutual representations,
covenants, promises and agreements hereinafter set forth, the Parties hereto,
intending to be legally bound, hereby covenant and agree as follows:





                                       E1


ARTICLE I - SCOPE OF WORK

         The Company shall, in accordance with the provisions set forth herein,
provide all labor, supervision, materials and equipment necessary to perform the
interconnection installation as more fully described in Attachment I, attached
hereto and made a part hereof, entitled "Scope of Work".

ARTICLE II - SCHEDULE OF WORK

         The Company shall use reasonable efforts to perform the Scope of Work
on a timely basis in accordance with the schedule set forth in Attachment II,
which is attached hereto and made a part hereof, entitled "Schedule of Work".

ARTICLE III - PAYMENT

         Power Producer shall pay the Company for the actual costs of all
services performed by the Company, as specified in Attachment I - Scope of Work.
Costs shall include, but not be limited to, all labor charges, expenses,
materials and equipment charges, subcontractor costs, overheads and all
applicable permits, fees and sales, use or any other taxes.

         Power Producer shall provide an advanced payment of $1,500,000.00 at
the time this Installation Agreement is executed. This amount shall be used by
the Company during the execution of the work first to offset AFUDC charges, then
to offset the final invoiced costs.

         The Company shall submit monthly invoices for work performed. Each
invoice shall include supporting documentation and shall state the dates of
performance covered by the


                                       E2


invoice. Invoices in the final stages of the project will be adjusted to credit
for the application of advance payment.

         Terms of payment shall be Net 30 days from the date of invoice
issuance. Interest shall be assessed on payments received after their due date
at the interest rate applied to prime commercial loans then in effect at the
main office of Citibank N.A., located in New York, N.Y. or its successor,
calculated from the due date to the date of payment.

         Power Producer may, at any time, assign its payment obligations
hereunder to the purchaser of the output of the Ironwood facility. Power
Producer shall provide the Company with such notice of such assignment,
identifying the assignee. Following receipt of such notice, the Company shall
direct its invoices under this Installation Agreement to the assignee with a
copy to Power Producer. No such assignment, however, shall release or in any way
discharge Power Producer from the performance of its obligations (including any
or all payment obligations) under this Installation Agreement.

ARTICLE IV - BONUS/LIQUIDATED DAMAGES

         If the actual completion date for Phase 1 varies from the date shown in
the Schedule of Work Attachment II, the following provisions shall apply:

         1. If the actual completion date is later than the scheduled completion
date, the Company will pay Power Producer Liquidated Damages in the amount of
$5,000.00 per day for each day by which the Phase 1 work is not complete for up
to and including 42 days delay (August 11, 2000).

         2. If the actual completion date is earlier than the scheduled
completion date, Power Producer will pay the Company a Bonus for early
completion in the amount of $5,000.00 per day for each day by which the Phase 1
work is completed early, for up to and including 30 days early


                                       E3


(May 31, 2000). It is understood by the Parties that the Company will utilize
overtime from time to time during the installation of the Interconnection
Facilities for the purpose of properly scheduling the work. Examples of this are
the use of overtime when working in active substations as required to minimize
the duration of substation outages or to complete work activities which are
better completed in one day rather than extending the work into a second day. It
is also understood by the parties that overtime is not intended to be used
purely for the benefit of accelerating schedule to achieve the Bonus. If
overtime is used for this purpose, the premium portion of overtime cost will be
deducted from the Bonus amount.


         If it becomes apparent at any time that the Company will not complete
the Phase 1 work within 42 days after the scheduled completion date, and the
Company cannot within 30 days (of the delay becoming known) propose a recovery
plan reasonably acceptable to Power Producer, then Power Producer shall have
step in rights to complete the work in accordance with Company's specifications
and pursuant to Good Utility Practice, provided that Power Producer can
demonstrate that they could complete more quickly than the Company.

         In further consideration of agreement to the Bonus/Liquidated Damages
provisions above and to an earlier agreement that the Company would proceed with
engineering before execution of the Installation Agreement and set the
completion date for Phase 1 work at June 30, 2000, Power Producer will pay the
Company for the work undertaken by the Company prior to December 17, 1998 in the
amount of $40,000. This payment shall be due within 30 days of signing this
Installation Agreement.



                                       E4
