|2.5  Eminent Domain.  In the event the Facility or the Facility Siteis to be taken in condemnation or expropriation proceedings or by exercise of any right of eminent domain, then this Agreement shall automatically terminate as of the date the condemning authority or the authority exercising its right of eminent domain takes possession or control of the Facility.

|3.8  Metering.  NEA shall maintain such metering as may be necessary pursuant to this Agreement and the Steam Agreement. Such metering shall be inspected and tested for accuracy as either party may reasonably elect and the party requesting the test shall bear the cost of such testing. All such inspection and testing shall be in accordance with applicable guidelines set forth by the National Bureau of Standards or other testing agency acceptable to BOC. If any meter is found to be inaccurate by more than two percent (2%), any billings based on such meter shall be adjusted to offset such inaccuracy with respect to only those deliveries made during the shorter of thirty (30) days prior to such test or the last half of the period of time since the last meter test. In addition to the foregoing, BOC may install, maintain and calibrate check meters at its sole expense.

NEA shall not be required to operate the NEA Plant solely to furnish Power to BOC, but at all times that NEA is providing Power at the NEA Plant, NEA must deliver sufficient Power to operate the Facility.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
|4.2  Power Specifications.  BOC may reject Power delivered to BOC under this Agreement to the Delivery Point if such Power is not of the same quality of Power as currently supplied to the Facility and such rejected Power shall be deemed as not having been delivered or made available for purposes of Sections 15.3 and 15.4.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
|4.3  Rentals.  For each month of the Operating Period, NEA shall bill BOC and BOC shall pay NEA the Base Rent and Additional Rent defined in the rent schedule set forth in Section I of Exhibit F. NEA shall submit a monthly invoice to BOC, on or before the 5th of each month, covering all Rents and other sums, if any, applicable to such month as well as all any rent applicable during the prior month not covered by the prior invoice. Such invoices shall be on a net cash basis, payable by BOC within twenty-five (25) days after receipt thereof. If for any reason the Facility is not operating and Power, Steam and Flue Gas are available (a "Facility Outage"), then BOC will continue to pay Base Rent, provided that if in any calendar year the number of hours of Facility Outage exceed 48, any Base Rent paid with respect to any Facility Outage hour after the 48th hour (prorated on an hourly basis) shall be applied as a credit by the end of the following calendar year on a dollar for dollar basis against Additional Rents for up to a total of two hundred forty (240) credit hours over a calendar year.

Upon the termination of this Agreement, the receiving party shall: (i) promptly return all Confidential Information of the disclosing party to it, whether in written or electronic form, and neither receiving party nor any of its employees shall retain any copies, extracts, or other reproductions thereof, in whole or in part, in any form whatsoever; and (ii) take reasonable steps to assure that all documents, memoranda, notes, and other writings or electronic records prepared by it which include or reflect any Confidential Information belonging to the disclosing party and cannot be returned pursuant to (i) above, are destroyed.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
|10.3  Irreparable Harm.  Receiving party recognizes that disclosing party and its Affiliates, if relevant, may suffer irreparable harm as a result of the unauthorized disclosure, reproduction or use of any Confidential Information and that monetary damages will be inadequate to compensate disclosing party for such breach. Therefore, receiving party agrees that in the event of any failure to comply with the provisions of this Section, disclosing party shall be entitled to seek a preliminary injunction, and any other equitable relief in order to protect and recover the Confidential Information.

All rights in inventions, designs and other intellectual property created or developed solely by BOC during the Operating Period with respect to the Facility shall be vested in BOC and NEA shall have a non-exclusive, royalty-free license to use such inventions, designs and other intellectual property at the Facility as necessary. BOC will notify NEA when it becomes aware of the creation or development of any such intellectual property.

|13.2  Notice and Defense.  In the event an Indemnitee seeks to be indemnified hereunder, it shall promptly notify the Indemnifying Party in writing of the facts and circumstances upon which any such Claim is based; provided that the failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder. The Indemnifying Party shall defend each Claim which is less than or equal to the amounts set forth in Section 13.3 with counsel of its sole choice and shall have the sole authority to settle or compromise the same. As long as the Indemnifying Party defends a Claim, the party bringing the Claim shall not be responsible for the fees of attorneys retained separately by it. Upon the Indemnifying Party's request, Indemnitee shall cooperate with the Indemnifying Party in the defense of each Claim with such cooperation including providing information necessary to answer interrogatories, producing requested documents and making employees available as witnesses at oral deposition and/or trial.

If a party is unable to perform any obligation in this Agreement because of Force Majeure, then, subject to Section 4.3, the obligations of that party shall be suspended to the extent and for the period of such Force Majeure condition, provided that: (i) the suspension of performance is of no greater scope and of no longer duration than is required by the Force Majeure event; (ii) the affected party uses reasonable endeavors to avoid and reduce the effects of the Force Majeure event, and to resume performance of its obligations; (iii) the affected party gives prompt written notice to the other party setting out the nature of the event of Force Majeure, the impact it will have on performance, and its expected duration, and provides status updates whenever there is any significant change.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
|15.3  Shortfall.  Each time that a Shortfall occurs for forty-eight (48) consecutive hours or more the Base Rent for the month shall be abated by an amount equal to the monthly Base Rent times the quotient obtained by dividing the number of hours a Shortfall existed minus 48 by the number of hours in the month. The abatement of the Base Rent shall be BOC's sole remedy for any failure by NEA to generate or deliver Power or Flue Gas to BOC and NEA shall not be in default hereunder for such failure if the Base Rent is abated.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
|15.4  Excused Performance.  BOC's performance under this Agreement of its obligations to take Power shall be excused for any period of time when the NEA Plant is operating only one gas turbine and it is operating on fuel oil or when the NEA plant is operating both gas turbines on fuel oil ("Oil Operations"). Such an event would prevent NEA from providing Flue Gas to the Facility from a gas turbine operating on natural gas and any monthly Base Rent due hereunder shall be abated by an amount equal to the Base Rent for the affected month times the quotient obtained by dividing the number of hours of Oil Operations within the month by the total number of hours in the month.

|16.2  Early Termination For Default.  This Agreement or any or all of the services to be provided hereunder may be terminated by either party (the "non-defaulting party") if any of the following events ("Events of Default") occur by or with respect to the other party (the "defaulting party"): (i) the defaulting party commits a material breach of any of its obligations hereunder (including a failure to make payment when due) and, subject to Section 22, fails to cure such breach within thirty (30) days of receipt of written notice from the non-defaulting party; (ii) any insolvency of the defaulting party, any filing of a petition in bankruptcy by or against the defaulting party, any appointment of a receiver for the defaulting party, or any assignment for the benefit of the defaulting party's creditors; provided, however, that in the case of any involuntary bankruptcy proceeding such right to terminate shall only become effective if the proceeding is not dismissed within sixty (60) days after the filing thereof; or (iii) the Steam Agreement or both flue gas agreements are terminateddue to a default by the defaulting party. Upon any Event of Default, in addition to its right to terminate this Agreement, a party may pursue any remedy available at law or in equity. In addition, if the Steam Agreement is terminated for any reason other than a default hereunder, this Agreement shall automatically terminate.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
|16.3  Special Termination Events.

For purposes of this Section "Special Termination Events" means (1) any Force Majeure event that results in any shutdown of the NEA Plant which lasts longer than three (3) months, (2) any renegotiation or termination of any of NEA's power sales agreements that either reduce the amount of Power available to BOC and required to operate the Facility or results or is expected to result in more than four (4) Shortfalls occurring over a one (1) month period, (3) the elimination of the requirement that NEA maintain the "qualifying facility" certification of the NEA Plant in order to comply with its power sales agreements, financing agreements or any applicable Legal Requirements, (4) any Major Repair or Replacement which exceeds or is expected to exceed a total cost to BOC of US$750,000 per calendar year, or a series of such Major Repairs or Replacements exceeding or expected to exceed a total of US$5,000,000 in the aggregate over the term of the Agreement net insurance recovery or any contributions made by NEA, (5) any Major Repair or Replacement to Front End Equipment, preventing operation of the Facility, that takes longer than three (3) months to repair or replace or (6) BOC's failure to take delivery of sufficient Steam as defined in Section 3 of the Steam Agreement over a twelve (12) month calendar period during the Operating Period or if NEA provides written notice to BOC on the last business day of August in each calendar year which indicates the amount of Steam required to be purchased by BOC thereunder and any forecasts related thereto over the remaining term of the calendar year to maintain NEA's "qualifying facility" certification and following such written notice, BOC fails to provide and follow a reasonable remediation plan to ensure consumption of such Steam prior to December 31st. Upon a Special Termination Event relating to (1), (2), (3) or, if NEA is unwilling to make its share of the contributions per (4) above, NEA shall pay BOC an amount equal to the Unamortized Capital Investment as of the date of termination within thirty (30) days after receiving from BOC an invoice therefore, together with supporting documentation.
|16.4  No Release.  Termination shall not release either party from any obligation or liability incurred prior to the date of termination. In all other respects, the rights and obligations of the parties to this Agreement which expressly or by implication come into or continue in force after the date of termination or expiration of this Agreement shall survive termination or expiration. Neither party shall have any liability to the other party for terminating the Agreement pursuant to this Section 16 except for termination pursuant to Section 16.2, 16.3 or as provided in Section 3.3.

|In the event that a party to this Agreement has reasonable grounds to believe that the other party hereto has failed or may fail to fulfill any obligation hereunder, or that its expectation of receiving due performance under this Agreement may be impaired, such party will promptly notify the other party in writing of the substance of its belief. The party receiving such notice must respond in writing within thirty (30) days of receipt of such notice and either provide evidence that the condition has been cured, or provide an explanation of why it believes that its performance is in accordance with the terms of this Agreement, and also specify three (3) dates, all of which must be within thirty (30) days from the date of its response, for a meeting to resolve the dispute. The claiming party will then select one (1) of the three (3) dates, and a dispute resolution meeting will be held. If the parties cannot, in good faith discussions, resolve their dispute, they will submit the dispute to senior executives representing each party who are authorized to resolve such dispute, respectively. Any resolution upon which these executives may agree will be final and binding on the parties. If said dispute cannot be settled within thirty (30) days after the initial request for a senior executive level meeting, the parties will attempt in good faith to resolve the dispute by mediation. The parties shall agree upon a neutral mediator chosen from the Center of Public Resources Judicial Panel to mediate efforts to arrive at a settlement. If the dispute has not been resolved pursuant to the aforesaid mediation procedure within sixty (60) days of the commencement of such procedure or if the parties do not agree to pursue mediation within sixty (60) days of the initial request for meeting, each party shall be free to pursue all its legal remedies.
