criminal), cost, suit, charge, expense (including reasonable attorneys fees) or
cause of action, arising from any damage to the PRODUCTION FACILITY resulting
from such reliance, except if such loss, damage, liability, cost, suit, charge,
expense or cause of action is the result of NIAGARA MOHAWK's willful misconduct
or gross negligence.

       2.3.4        NIAGARA MOHAWK reserves the right to operate the first means
of disconnect on the PRODUCER'S side of the INTERCONNECTION POINT in accordance
with GOOD UTILITY PRACTICE.

       2.3.5        Upon implementation of an ISO and at NIAGARA MOHAWK'S sole
discretion, the requirements, rules and regulations of the ISO may govern
requirements of ELECTRIC SYSTEM BULLETIN No. 756.

any right to transmit electricity over NIAGARA MOHAWK'S TRANSMISSION SYSTEM
other than through the INTERCONNECTION FACILITIES.

       2.5          NIAGARA MOHAWK shall use due diligence, in accordance with
GOOD UTILITY PRACTICE, to operate and maintain the INTERCONNECTION FACILITIES
and to have them available for the transmission of electricity. NIAGARA MOHAWK
shall consult with PRODUCER regarding the timing of scheduled maintenance of the
INTERCONNECTION FACILITY, which might reasonably be expected to affect
PRODUCER'S PRODUCTION FACILITY. NIAGARA MOHAWK shall, to the extent practicable,
schedule any maintenance to coincide with PRODUCER'S scheduled outage. NIAGARA
MOHAWK does not, however, guarantee or warrant uninterrupted availability of the
INTERCONNECTION FACILITIES or TRANSMISSION SYSTEM. Curtailment of deliveries
over the INTERCONNECTION FACILITIES or TRANSMISSION SYSTEM shall be governed by
the transmission agreement or agreements between NIAGARA MOHAWK and the
PRODUCER.

       2.6          PRODUCER hereby grants NIAGARA MOHAWK all necessary rights
of way, easements, and licenses as NIAGARA MOHAWK may reasonably require to
install, operate, maintain, replace and remove NIAGARA MOHAWK'S facilities,
including adequate and continuing rights of access to PRODUCER'S property for
any purpose reasonably related to this AGREEMENT. PRODUCER hereby agrees to
execute such grants, deeds, licenses, instruments or other documents as NIAGARA
MOHAWK may require to enable it to record such rights of way, easements and
licenses.

       2.7          NIAGARA MOHAWK hereby grants PRODUCER all necessary rights
of way, easements, and licenses as PRODUCER may reasonably require to install,
operate, maintain, replace and remove PRODUCER'S facilities, including adequate

right arising from NIAGARA MOHAWK'S ownership of the INTERCONNECTION FACILITY
which different or additional tax would not be required to be paid by NIAGARA
MOHAWK in the absence of this AGREEMENT and, with respect to such different or
additional tax, no obligation of PRODUCER to participate or pay would have
attached under the provisions of this AGREEMENT elsewhere than in this
paragraph, then in such event PRODUCER and NIAGARA MOHAWK shall agree upon an
equitable allocation of such different or additional tax.

the INTEREST RATE until date paid. Inadvertent overpayments shall

                                       15

be returned by NIAGARA MOHAWK upon request or deducted by NIAGARA MOHAWK from
subsequent payments, with interest accrued at the INTEREST RATE from the date
originally paid until the date paid or deducted.

       8.5          In the event that NIAGARA MOHAWK is the purchaser of power
from the PRODUCTION FACILITY, any outstanding invoices which the PRODUCER has
not paid to NIAGARA MOHAWK shall be deducted from the payments due PRODUCER by

       10.1         This AGREEMENT shall become effective as of the date first
above written (the "EFFECTIVE DATE"), subject to its approval or acceptance for
filing by the FERC, and shall continue in effect for ten (20) years.

       10.2         This AGREEMENT shall not merge with or be terminated or
superseded by any future agreement between the parties that does not
specifically so provide.

       10.3         In the event PRODUCER abandons the PRODUCTION FACILITY;
becomes insolvent; or assigns or sublets this AGREEMENT in a manner inconsistent
with this AGREEMENT, or is violating any of the material conditions, terms,
obligations, or covenants of this AGREEMENT, NIAGARA MOHAWK may terminate this
AGREEMENT. Before instituting proceedings before FERC to terminate the
AGREEMENT, NIAGARA MOHAWK must give PRODUCER written notice of the reasons for
termination. If within a period of thirty (30) days of such notice PRODUCER
cures the default or breach cited by NIAGARA MOHAWK in such notice, to the
reasonable satisfaction of NIAGARA MOHAWK, and shall have complied with the
provisions of this AGREEMENT, such notice shall become null and void and of no
effect. Notwithstanding the foregoing, NIAGARA MOHAWK and PRODUCER may
terminate this AGREEMENT upon mutual agreement set forth in writing; provided,
however that the requesting party provides at least sixty (60) days written
notice of intent to terminate.

8.4 of this AGREEMENT between NIAGARA MOHAWK and the PRODUCER, NIAGARA MOHAWK
will not apply to remove the INTERCONNECTION FACILITIES from service or to
terminate transmission service thereon as long as the PRODUCER: (i) continues to
make all payments not in dispute and (ii) pays into an independent escrow
account the portion of the invoice in dispute, pending resolution of such
dispute. If the PRODUCER fails to meet these two requirements, then a default
shall be deemed to exist, to which the procedures set forth in this section for
the disconnection of the INTERCONNECTION FACILITIES from service shall apply.

       10.5         Termination of this AGREEMENT shall not relieve PRODUCER of
any of its liabilities and obligations arising hereunder prior to the date
termination becomes effective, and NIAGARA MOHAWK may take whatever judicial or
administrative actions as appear necessary or desirable to enforce its rights
hereunder. The rights specified herein are not exclusive and

                                       17
<PAGE>   19

shall be in addition to all other remedies available to NIAGARA MOHAWK, either
at law or in equity, for default or breach of any provision of this AGREEMENT.

but was built in accordance with GOOD UTILITY PRACTICE and does not present any
adverse impact on NIAGARA MOHAWK 's TRANSMISSION SYSTEM as determined by NIAGARA
MOHAWK in its reasonable discretion, then it is not the intent of this AGREEMENT
to cause the PRODUCER's PRODUCTION FACILITY to immediately upgrade to full
compliance with ELECTRIC SYSTEM BULLETIN No. 756. Any upgrades required to
protect NIAGARA MOHAWK's TRANSMISSION SYSTEM from adverse impacts Will be listed
in Exhibit B and must be completed within ninety (90) days of signing this

necessary for safety, such portion of the PRODUCER's PRODUCTION FACILITY, as is
necessary, will bc brought into full compliance with the requirements of
ELECTRIC SYSTEM BULLETIN No. 756, at that time.

               2.3.3    If PRODUCER relies on NIAGARA MOHAWK's system
protection equipment and practices for protection of PRODUCTION FACILITY
equipment, PRODUCER agrees to indemnify, defend, and save NIAGARA MOHAWK, its
agents and employees, harmless from, and against any loss, damage, liability
(civil or criminal), cost, suit, charge, expense (including reasonable attorneys
fe:s) or cause of action, arising from any damage to the PRODUCTION FACILITY
resulting from such reliance, except if such loss, damage, liability, cost,
suit, charge, expense or cause of action is the result of NIAGARA MOHAWK's
willful misconduct or gross negligence.

               2.3.4    Upon implementation of an ISO and at NIAGARA MOHAWK's
sole discretion, the requirements, rules and regulations of the ISO may govern
requirements of ELECTRIC SYSTEM BULLETIN No. 756.

schedule any maintenance to coincide with PRODUCER's scheduled outage. NIAGARA
MOHAWK does not, however, guarantee or warrant uninterrupted availability of the
INTERCONNECTION FACILITIES or TRANSMISSION SYSTEM. Curtailment of deliveries
over the INTERCONNECTION FACILITIES or TRANSMISSION SYSTEM shall be governed by
the transmission agreement or agreements between NIAGARA MOHAWK and the PRODUCER
