ARTICLE I.  Definitions

     A.   Unless otherwise specified in this Contract, the terms used herein
          shall have the same meanings as those used in the Steam Purchase
          Contract (as defined below).  Where the word "steam" is used in the
          relevant definition in the Steam Purchase Contract, for the purposes
          of this Contract, the word "electricity" shall be understood unless
          the context requires otherwise.
     B.   "JCP&L" shall mean Jersey Central Power & Light Company.
     C.   "Steam Purchase Contract" shall mean that certain Steam Purchase

ARTICLE V.  Operation of the Cogeneration Facility.
     A.   O'Brien has agreed with Du Pont in the Steam Purchase Contract to
operate the Facility to furnish steam to Du Pont.  In addition to the
commitments made in the Steam Purchase Contract, O'Brien agrees to the
further provisions in this Article V to allow O'Brien to supply NPI with
the electricity covered by this Contract.
     B.   O'Brien agrees to maintain the Facility with a capacity adequate
to deliver at least 9MW of electricity to NPI for resale to Du Pont on a
continuous basis.  To ensure this capacity, O'Brien will operate and
maintain the two Frame Six Combustion Turbine Combined Cycle Systems
installed in the Facility pursuant to Article V.B of the Du Pont Contract.
     C.   In the event O'Brien fails to supply NPI's electricity
requirements for a period of six consecutive months or, in the alternative,
if O'Brien notifies NPI that it can no longer meet such requirements,
O'Brien will immediately make available to NPI for NPI's or Du Pont's use
all equipment necessary for NPI to serve Du Pont from the 230kv system
until the service hereunder can be returned to the 34.5kv system or until
Du Pont finds other electric service acceptable to Du Pont.  O'Brien shall
obtain in its loan agreement any necessary waiver from its lender to permit
NPI to exercise the foregoing option.  Furthermore, O'Brien shall maintain
the two 13.8kv to 2.4kv transformers referred to in Article V.C of the Du
Pont Contract in such way that they can be replaced with 34.5kv to 2.4v
transformers and reconnected to the existing JCP&L feeders.  To the extent
JCP&L requires Du Pont to pay for this conversion, O'Brien agrees to
reimburse NPI for any contribution it is required to make toward the cost
of such conversion under Article V.C. of the Du Pont Contract.

ARTICLE VI.  Interconnection with Du Pont's Plant

     A.   O'Brien will be responsible for the maintenance of all equipment
and systems above the Point of Interconnection as shown on Exhibit "A" to
the Du Pont Contract.
     B.   O'Brien will provide any reasonable assistance and support
required by NPI to enable NPI to implement and further develop the written
operating procedures referred to in Article VI.B of the Du Pont Contract.

ARTICLE VII.  Service Interruptions
     A.   Subject to force majeure and normal maintenance requirements,
O'Brien agrees to provide a continuous supply of electricity to NPI at the
quantities and characteristics described in Article II hereof.
     B.   O'Brien agrees to consult with NPI and Du Pont on a regular basis
and to schedule, to the extent reasonably possible, all routine maintenance
of the electrical generating system to coincide with periods when Du Pont's
operations are shut down or Du Pont's electricity needs are reduced.
     C.   If for any reason other than force majeure O'Brien fails to
provide NPI with the contract amounts of electricity and replacement power
is not received by Du Pont from JCP&L due to the fault of O'Brien, O'Brien
will reimburse NPI for any liability to Du Pont or NPI suffers under
Article VII.C of the Du Pont Contract.

                                5

<PAGE>

ARTICLE VIII.  Priority of Service
     If at any time O'Brien is unable to supply the contract amounts of
electricity to both NPI and to JCP&L, it shall first supply NPI needs up to
the contractual amount before supplying any other customer for its
electricty.

ARTICLE IX.  Standby Power
     A.   O'Brien will compensate NPI for any amount that NPI pays Du Pont
under Article IX.A of the Du Pont Contract.
     B.   O'Brien guarantees to NPI that the bill paid by Du Pontn to JCP&L
will be capped at the then current General Service Primary Rate defined in
Article IV of the Du Pont Contract.
     C.   If at any time O'Brien's performance hereunder effects NPI's
performance under the Electricity Purchase Contract such that JCP&L, in
accordance with its Standby Tariff and other applicable rules, requires Du
Pont to sign a firm power contract in order to continue receiving power,
and O'Brien terminates the Du Pont Contract, NPI shall have the right to
terminate its obligation to purchase electricity from O'Brien, effective as
of the same date that Du Pont terminates the Du Pont Contract.  Such
termination shall not affect Du Pont's or NPI's right or O'Brien's
obligation to continue the electrical interconnection parts of this
Contract, and O'Brien will take all reasonable steps to assure
uninterrupted electrical service from JCP&L to Du Pont.

                                6

<PAGE>

     D.   If JCP&L's tariffs or the rules of the New Jersey Board of Public
Utilities change so that Du Pont cannot receive the equivalent of firm
power without signing a new contract with JCP&L, and Du Pont exercises the
right contained in Article IX.C of the Du Pont Contract to reduce purchases
from NPI to the extent power is purchased from JCP&L under such new
contract, NPI may make a corresponding reduction in its purchases from
O'Brien hereunder.
ARTICLE X.  Metering.
     A.   O'Brien will own, operate, and maintain all necessary meters and
associated equipment, including, without limitation, generation metering
and telemetering equipment, utilized for measuring energy deliveries and
for determining NPI payments to O'Brien.  The metering point will be at the
point as shown on Exhibit "A" to the Du Pont Contract.  O'Brien will
provide Du Pont with such access and other reasonable assistance Du Pont
requires should Du Pont decide to install check meters as provided in
Article X.A of the Du Pont Contract.
     B.   O'Brien shall permit Du Pont employees and NPI's employees to
enter upon its leased premises at any reasonable time for the purpose of
inspecting and/or testing or witnessing the testing of the accuracy of the
metering equipment.
     C.   O'Brien shall (and shall permit Du Pont to) inspect, test, and
calibrate their respective equipment at regular intervals of not more than
one (1) year, as agreed between the parties, and any inaccuracy in the
O'Brien meters disclosed by such tests shall be promptly corrected.
O'Brien shall allow Du Pont any required access to enable Du Pont to
promptly correct inaccurate Du Pont meters disclosed by such tests.
O'Brien, NPI and Du Pont shall have the right to have any meter tested at
any time at its expense.  Representatives of teh other party

                                7

and of Du Pont shall be afforded a reasonable opportunity to be present at
all meter inspections and tests.  If at any time a meter is found
inaccurate by more than 1% an adjustment shall be made in settlements
between the parties to compensate for the effect of such inaccuracy over a
preceding period of thirty (30) days from removal or testing of the meter
or over any shorter period during which such inaccuracy may be determined
to have existed.  It at any time a meter should fail to register or its
registration should be so erratic as to be meaningless, the quantities such
meter was intended to record shall be determined from check meters, if
available, or otherwise from the best obtainable data.

ARTICLE XI.  Billings, Credits and Payments
     At the time that it would have billed Du Pont under the Du Pont
Contract, O'Brien will prepare a monthly bill and bill NPI for the
electricity purchased by NPI during the previous month.  Each invoice will
include all necessary information for calculation of the payment pursuant
to Article IV hereof, and credit NPI each month for any credits due to Du
Pont under Article XI of the Du Pont Contract.  Payment shall be made by
NPI contemporaneously with each receipt of payment by NPI from Du Pont
pursuant to the Du Pont Contract.  Should NPI fail to pay any invoice
within thirty (30) days after receipt, O'Brien, in addition to collecting
the interest set out herein, may pursue any viable remedy at law or in
equity.
