                                   ARTICLE II
                           AGREEMENT TO INTERCONNECT
                    DESCRIPTION OF INTERCONNECTION FACILITY

2.1    NIAGARA MOHAWK and PRODUCER agree to remain interconnected in accordance
       with the terms agreed to herein.

2.2    NIAGARA MOHAWK and PRODUCER shall be interconnected by means of the
       INTERCONNECTION FACILITY, which NIAGARA MOHAWK shall operate, own and
       maintain, at the PRODUCER's expense.

2.3    The PRODUCTION FAC1LITY shall include all facilities and equipment on the
       PRODUCER's side of the INTERCONNECTION POINT as indicated on Exhibit A.
       PRODUCER agrees that the installation of the electrical equipment and the
       operation of the PRODUCTION FACILITY must meet or exceed the requirements
       of NIAGARA MOHAWK'S ELECTRIC SYSTEM BULLETIN No. 756. Notwithstanding the
       foregoing, NIAGARA MOHAWK acknowledges and agrees to the following
       limitations for the existing PRODUCTION FACILITY as it pertains to
       NIAGARA MOHAWK'S ELECTRIC SYSTEM BULLETIN No. 756:

       2.3.1  If at the date of this AGREEMENT the PRODUCTION FACILITY does not
              conform to NIAGARA MOHAWK'S ELECTRIC SYSTEM BULLETIN No. 756, 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 AGREEMENT unless otherwise mutually agreed upon by
              both parties.


                                       4
   6


       2.3.2  The parties agree that it is the intent of this AGREEMENT to
              require the PRODUCER'S PRODUCTION FACILITY to conform to ELECTRIC
              SYSTEM BULLETIN No. 756 and therefore, agree that as additions,
              modifications and replacements to PRODUCER'S PRODUCTION FACILITY
              are implemented, the additions, modifications and replacements
              will conform to ELECTRIC SYSTEM BULLETIN No. 756. If the PRODUCER
              upgrades the system protection or upgrades technology employed at
              the PRODUCTION FACILITY (for example, but not limited to,
              repowering), if in NIAGARA MOHAWK'S reasonable discretion, it is
              necessary for safety, such portion of the PRODUCER'S PRODUCTION
              FACILITY, as is necessary, will be 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 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. PRODUCER reserves the right
              to operate the circuit breakers on NIAGARA MOHAWK'S side of the
              INTERCONNECTION POINT for synchronization and disconnection of
              Generators 63, 64, 65 and 66 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.

2.4    PRODUCER recognizes that neither this AGREEMENT nor the PRODUCER'S
       financial support of the INTERCONNECTION FACILITIES


                                       5
   7


       confers upon it 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 and continuing rights of access to NIAGARA MOHAWK'S property for
       any purpose reasonably related to this AGREEMENT. NIAGARA MOHAWK hereby
       agrees to execute such grants, deeds, licenses, instruments or other
       documents as PRODUCER may require to enable it to record such rights of
       way, easements and licenses.

       at PRODUCER's expense, any such new section as part of the
       INTERCONNECTION FACILITY, and PRODUCER shall reimburse NIAGARA MOHAWK for
       all costs of operating and maintenance expenses for any new section of
       the INTERCONNECTION FACILITY in accordance with Article VIII.

4.10   PRODUCER acknowledges and agrees that NIAGARA MOHAWK reserves the rights
       and ability to deliver ELECTRICITY to all customers. If, during the term
       of this AGREEMENT, NIAGARA MOHAWK determines that it is necessary to
       relocate or rearrange the INTERCONNECTION POINT, in order to permit
       NIAGARA MOHAWK access or to deliver electricity to its customers or new
       customers, so that a change is required to a section of the
       INTERCONNECTION FACILITY, NIAGARA MOHAWK shall put forth its best efforts
       to give the PRODUCER no less than one (1) year's written notice of such
       relocation or rearrangement and shall use all reasonable efforts to defer
       such relocation or rearrangement until the INTERCONNECTION FACILITY can
       be reconfigured so that service to PRODUCER may continue without
       interruption. Such relocation or rearrangement as referenced in this
       paragraph 4.10 shall be at NIAGARA MOHAWK's or the customer(s)' expense.

4.11   If PRODUCER plans any unit retirements to the PRODUCTION FACILITY,
       PRODUCER shall put forth its best efforts to give NIAGARA MOHAWK
       reasonable notice. NIAGARA MOHAWK and PRODUCER shall amend this AGREEMENT
       to reflect such unit retirements including but not limited to adjustments
       to Article VIII of this AGREEMENT.

       5.1.4  If, at any time, any metering equipment is found to be inaccurate
              by more than the limits defined in 16 NYCRR Part 92 as may be
              amended from time to time, NIAGARA MOHAWK shall cause such
              metering equipment to be made accurate or replaced at PRODUCER'S
              expense. Meter readings for the period of inaccuracy shall be
              adjusted so far as the same can be reasonably ascertained;
              provided, however, no adjustment prior to the beginning of the
              preceding month shall be made except by agreement of the parties.
              Each party shall comply with any reasonable request of the other
              concerning the sealing of meters, the presence of a representative
              of the other party when the seals are broken and the tests are

       5.1.6  Within sixty (60) days of the closing of the sale of the
              PRODUCTION FACILITY by NIAGARA MOHAWK, NIAGARA MOHAWK will take
              all necessary actions to bring the PRODUCTION FACILITY and the
              INTERCONNECTION FACILITY into full compliance with the
              requirements and specifications set forth in Sections 5.1.1
              through 5.1.5. Upon written certification by NIAGARA MOHAWK that
              the PRODUCTION FACILITY and INTERCONNECTION FACILITY are in
              compliance with Sections 5.1.1 through 5.1.5 then all subsequent
              compliance shall be PRODUCER'S responsibility.

5.2    LOSSES

       5.2.1  If the metering equipment and the DELIVERY POINT are not at the
              same location, the metering equipment shall record delivery of
              electricity in a manner that accounts for losses occurring between
              the metering point and the DELIVERY POINT. If the metering
              equipment does not have the capability of accounting for said
              losses, then either party may install metering equipment to
              account for said losses or the meter readings shall be multiplied
              by a loss factor to be mutually agreed to between NIAGARA MOHAWK
              and PRODUCER on the EFFECTIVE DATE to account for said losses
              between the metering point and the DELIVERY POINT. The metering
              point, DELIVERY POINT, associated equipment and distance between
              the metering point and the DELIVERY POINT shall be specified in
              Exhibit A.

5.3    REACTIVE POWER SUPPORT

       5.3.1  PRODUCER is required to provide reactive capability to regulate
              and maintain system voltage at the DELIVERY POINT in conformance

5.4    OPERATING FREQUENCY

5.4.1  PRODUCER is responsible for the proper coordination of any applied
       under/over frequency generator tripping as per 756, Appendix C, Section
       II, A, 2.7. If the PRODUCTION FACILITY elects to employ under frequency
       generator tripping protection, then the under frequency relay set point
       MUST be on or below the under frequency curve referred to in 756,
       Appendix C, Section IV, A., 3.0, Exhibit C-1. Similarly, if the
       PRODUCTION FACILITY elects to employ over frequency generator tripping
       protection, then the over frequency relay set point MUST be on or above
       the over frequency curve referred to in 756, Appendix C, Section IV, A.,
       3.0, Exhibit C-1. If the PRODUCTION FACILITY decides that, after
       consultation with NIAGARA MOHAWK, it cannot meet the under frequency
       -tripping set point limitation referred to in Exhibit C-1, then PRODUCER
       shall agree to fund the cost incurred by NIAGARA MOHAWK to install and
       maintain compensatory load shedding equipment required by the NYSRC. If
       the PRODUCER decides that it cannot meet the over frequency tripping set
       point limitation referred to in Exhibit C-1, PRODUCER shall consult with
       NIAGARA MOHAWK and NIAGARA MOHAWK will notify PRODUCER of any
       consequences associated with that decision.

5.5    OPERATING VOLTAGE

       5.5.1  PRODUCER is expected to adhere to the operating voltage
              performance referred to in 756 Appendix C, Section II, B, 2.2 and
              756 Appendix C, Section IV, B. PRODUCER is responsible for the
              proper coordination of any applied under/over voltage generator
              tripping as per 756, Appendix C, Section II, A, 2.7. If the
              PRODUCER elects to employ over voltage or under voltage
              protection, then the over voltage and under voltage relay settings
              shall be reviewed and approved by NIAGARA MOHAWK.

5.6    ISLANDING

       5.6.1  With reference to 756, Appendix C, Section II, A, 2.4, NIAGARA
              MOHAWK reserves the right to require, allow or prevent the
              ISLANDING of PRODUCER'S generation depending upon the

              tax); provided, however, that NIAGARA MOHAWK and PRODUCER shall
              agree upon an equitable allocation of any such taxes between the
              parties. If any form of tax, other than income or excess profits
              tax, under any present or future federal, state or other law
              different from or in addition to the taxes for which participation
              in or payment by PRODUCER is provided herein or elsewhere in this
              AGREEMENT, should be levied or assessed against or incurred by
              NIAGARA MOHAWK with respect to any property or property 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.

       8.2.8  NIAGARA MOHAWK agrees to cooperate with PRODUCER in attempting to
              minimize costs under this Article, provided PRODUCER reimburses
              NIAGARA MOHAWK for all costs incurred by NIAGARA MOHAWK in
              connection with such cooperation, including reasonable attorneys
              fees, and provided further that PRODUCER shall indemnify, defend,
              and save harmless NIAGARA MOHAWK its agents and employees, against
              any and all penalties, judgments, fines civil or criminal, or
              other costs that may be imposed by any governmental authority as a
              result of actions undertaken at the specific request or
              concurrence of the PRODUCER.

8.4    Billing Disputes. If PRODUCER, in good faith, disputes an invoice,
       PRODUCER shall immediately notify NIAGARA MOHAWK of the basis for the
       dispute and pay the portion of such statement conceded to be correct no
       later than the due date. Consistent with Section 10.4 herein, if any
       amount withheld under dispute by PRODUCER is ultimately determined (under
       terms herein) to be due to NIAGARA MOHAWK, said funds held in escrow
       shall be paid to NIAGARA MOHAWK within one (1) Business Day of such
       determination along with interest accrued at the INTEREST RATE until date
       paid. Inadvertent overpayments shall 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 NIAGARA MOHAWK.

9.2    Either party may change its address for notices by notice to the other in
       the manner provided above.

9.3    Notwithstanding paragraph 9.1, any notice hereunder, with respect to a
       system emergency or other occurrence requiring prompt attention, may be
       made by telephone provided that such notice is confirmed in writing
       promptly thereafter.

9.4    These representatives as noted in paragraph 9.1 or their designees shall
       be authorized to act on behalf of the parties, and their instructions,
       requests, and decisions will be binding upon the parties as to all
       matters pertaining to this AGREEMENT and the performance of the parties
       hereunder. Only these representatives shall have the authority to commit
       funds or make binding obligations on behalf of the parties. These
       representatives shall be responsible for tracking work, costs, schedules
       and all other matters related to this AGREEMENT, and to the performance
       of any third parties.


                                   ARTICLE X
                              TERM AND TERMINATION

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 twenty (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.


                                       21
   23


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.

10.4   In the event of a billing dispute as set forth in Section 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 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.

10.6   In the event of termination of this AGREEMENT in accordance with Article
       X, NIAGARA MOHAWK will physically disconnect the PRODUCTION FACILITY from
       the TRANSMISSION SYSTEM and at NIAGARA MO-

       INTERCONNECTION FACILITY equipment.

                                 FORCE MAJEURE

11.1   Neither party shall be considered to be in default or breach hereunder,
       and shall be excused from performance hereunder, if and to the extent
       that it shall be delayed in or prevented from performing or carrying out
       any provisions of this AGREEMENT by reason of storm, flood, lightning
       strikes, earthquake, fire, ice, snow, epidemic, war, invasion, riot,
       civil disturbance, sabotage, explosion, insurrection, military or usurped
       power, strikes, stoppage of labor, labor dispute, failure of contractors
       or suppliers of material, action of any court or governmental authority,
       or any civil or military authority de facto or de jure, change in law,
       act of God or the public enemy, or any other cause beyond either party's
       control; including, without limitation, disconnection or limited
       operation of NIAGARA MOHAWK'S electric system, unscheduled repairs or
       maintenance, fuel or energy shortages, or equipment breakdown.

11.2   The party claiming force majeure shall use due diligence to resume
       performance or the provision of service hereunder as soon as practicable.

11.3   Neither party shall be liable to the other party for or on account of any
       loss, damage, injury or expense, including, but not limited to, special,
       indirect and consequential damages, resulting from or arising out of such
       delay or inability to perform.

                          RELATIONSHIP OF THE PARTIES

       employee, principal agent, or any other business association, with

       purport to act as the other party's agent or legal empowered
       representative for any purpose whatsoever.

12.3   Neither party shall be liable to any third party in any way for any
       engagement, obligation, commitment, contract, representation or for any
       negligent act or omission to act of the other party, except as expressly
       provided for herein.

12.4   The rights and obligations of the parties shall be limited to those
       expressly set forth herein.

13.1   No person or party shall have any rights or interests, direct or
       indirect, in this AGREEMENT or the services or facilities to be provided
       hereunder, or both, except the parties, theft successors, and authorized
       assigns.

       person or party as a third-party beneficiary to this AGREEMENT or to the
       services or facilities to be provided hereunder, or both.

13.3   PRODUCER may assign or collaterally assign this AGREEMENT to lenders, or
       any financial institution participating in financing PRODUCER's
       INTERCONNECTION FACILITY or property acquisition, or to any partnerships
       created to operate PRODUCER's facilities, or to any other parties,
       including affiliates or partnerships, upon prior written notification to
       NIAGARA MOHAWK

13.4   PRODUCER agrees to reimburse NIAGARA MOHAWK for costs and expenses
       (including reasonable fees and expenses of NIAGARA MOHAWK'S counsel)
       incurred in connection with NIAGARA MOHAWK'S review, execution and
       delivery of instruments, agreements or documents necessary in connection
       with the PRODUCER'S assignment, transfer, sale or


                                       24
   26

       AGREEMENT.

13.7   PRODUCER shall not make any assignment unless and until its successor in
       interest has agreed to undertake the obligations accepted by PRODUCER
       herein, and has provided written assurances to NIAGARA MOHAWK of
       continued performance and protection against liability upon assignment.

13.8   Assignment contrary to the provisions of this AGREEMENT shall make
       PRODUCER the indemnitor of NIAGARA MOHAWK and its successors, against any
       liabilities and costs, including reasonable attorneys fees as to which
       PRODUCER'S transferee fails to indemnify, defend, and hold harmless

       charge, expense (including reasonable attorneys fees) or cause of action,
       whether unconditionally certain or otherwise, incurred by NIAGARA MOHAWK
