Subject to the terms and conditions set forth below and provided that the Closing Date occurs on or prior to the Expiration Date the Parties agree that the Contract shall be terminated effective as of 9:59 a.m. (Eastern time) on November 1, 2005 (the " Termination Date "), and each Party agrees to deliver to the other a certificate acknowledging that the Release is effective as of the Termination Date. The delivery of such certificates shall not be a condition to the termination of the Contract or to the obligation of the Parties to make the Termination Payment pursuant to Section 3.1(a), herein.

2.2 Termination of Agreement . This Agreement shall be effective as of the Effective Date. If the Closing Date does not occur on or prior to March 31, 2005 (or such later date as extended pursuant to Section 3.1(a) or by mutual written agreement of the Parties) (the " Expiration Date "), this Agreement shall terminate effective 12:01 a.m. Eastern time on the first Business Day following the Expiration Date, unless this Agreement is terminated earlier pursuant to Section 2.3(c), 3.2(a) or Section 3.2(b).

2.3 ProGas Covenants Pending Closing .

(a) Beginning on the Effective Date, ProGas shall use commercially reasonable efforts to obtain at its sole cost and expense, as promptly as practicable:

(d) If NEA terminates this Agreement by delivery of a termination notice in accordance with Section 2.3(c), this Agreement shall terminate as of the date of such notice and be of no further force and effect. In the event of such termination, the Contract shall continue in full force and effect, unamended and unaffected by virtue of this Agreement; provided, however, such termination shall not release either Party from any claims by the other Party that it did not use commercially reasonable efforts in connection with its obligations under Sections 2.3 or 2.4 as applicable.

(e) ProGas covenants and agrees that once any of the TCPL Consent, the Required Ballots or the Producer Approval is obtained, ProGas shall not take or consent to the taking of any action to rescind, cancel or abrogate the effectiveness or finality of the TCPL Consent, the Required Ballots or the Producer Approval.

(b) NEA covenants and agrees that once the NEA PPA Restructuring and the Corporate Approvals have been obtained in accordance with Section 2.4(a), NEA shall not take any action to rescind, cancel or abrogate the effectiveness or finality of the Corporate Approvals; provided, however, it is understood and agreed that the finality of the NEA PPA Restructuring shall be contingent upon receipt of the Corporate Approvals.

(c) Beginning on the Effective Date, NEA shall use commercially reasonable efforts and due diligence to consummate, at NEA's sole cost and expense, as promptly as practicable, the term restructuring of the four (4) power purchase agreements between NEA and certain utility subsidiaries of NSTAR Electric & Gas Corporation (" NSTAR ") (the " NEA PPA Restructuring ") on terms and conditions acceptable to NEA; provided however , if NEA notifies ProGas in writing that NEA has determined that the NEA PPA Restructuring cannot be consummated consistent with such acceptable terms and conditions, then NEA shall be released from any and all obligations under this Section 2.4(c) and shall have no liability hereunder to ProGas for failure to pursue a NEA PPA Restructuring.

The calculation of the NYMEX Final Price and the calculation of the Termination Payment by ProGas in accordance with Section 3.2 shall occur on the Business Day after NEA delivers the Closing Notice (the " Termination Payment Calculation Date "). The date upon which: (i) the conditions precedent set forth in Sections 2.5 and 2.6 have been satisfied, and, (ii) a final Termination Payment has been determined in accordance with Sections 3.2 and 3.4 and has been agreed to by ProGas and NEA or as otherwise determined in accordance with Section 3.2(a) or (b), shall be the closing date (or as otherwise mutually agreed to by the Parties) (the " Closing Date "). On the Termination Date, the Termination Payment shall be paid in accordance with Section 3.5 and the Parties shall execute and deliver the Release certificate as contemplated in Section 2.1.

(b) The Parties acknowledge and agree that the Closing Date will occur prior to the Termination Date and that nothing in this Agreement shall modify, relieve or excuse ProGas' or NEA's respective obligations to deliver, receive and pay for, the full Daily Contract Quantity of 12,507 MMBtus/day under the Contract through 9:59 a.m. (Eastern time) on the day following the Termination Date.

3.2 Calculation of Termination Payment . The " Base Termination Payment " shall be equal to (1) negative nine million five hundred thousand U.S. dollars (-US$9,500,000) plus (2) the product of negative twenty-eight million two hundred thousand U.S. dollars (-US$28,200,000) times the NYMEX Price Differential. An example of this calculation is shown on Appendix B .

(a) NEA shall have no obligation to make an NEA Termination Payment to ProGas and, as such, the NEA Payment Cap is zero U.S. dollars (US$0) (the " NEA Payment Cap "); provided, however, if the Base Termination Payment is a positive number, then NEA may elect to pay to ProGas the NEA Termination Payment, which shall be an amount equal to the Base Termination Payment. If the Base Termination Payment exceeds the NEA Payment Cap, then:

(1) ProGas shall notify NEA, concurrently with providing documentation of its calculation of the amounts in Section 3.2(a) above, as to whether ProGas elects to accept payment of the NEA Termination Payment in the amount of the NEA Payment Cap, or

(2) If ProGas' notice provided for in Section 3.2(a)(1) states that ProGas declines to accept the election described in Section 3.2(a)(1), then within one (1) Business Day of receipt of such notice, NEA shall notify ProGas as to whether NEA agrees to waive the NEA Payment Cap and pay to ProGas the NEA Termination Payment in the amount of the Base Termination Payment.

If ProGas declines to accept its election under Section 3.2(a)(1) and NEA declines to exercise its election under Section 3.2(a)(2), then the Parties shall enter good-faith negotiations, for a period not to exceed two (2) Business Days from the date NEA declines to exercise its waiver provided for in Section 3.2(a)2, during which time the Parties shall seek to arrive at a mutually acceptable NEA Termination Payment. Notwithstanding the Parties' agreement to negotiate in good faith, NEA shall not be obligated to make any NEA Termination Payment exceeding the NEA Payment Cap unless NEA agrees to make such a payment in its sole discretion. If the Parties' good faith negotiations do not result in a mutually acceptable NEA Termination Payment within two (2) Business Days, then this Agreement shall terminate unless the parties mutually agree to extend the period for good faith negotiations.

(b) If the Base Termination Payment is a negative number, then ProGas shall pay to NEA the ProGas Termination Payment, which shall be an amount equal to the Base Termination Payment multiplied by negative one (-1), but in no event in excess of twenty-five million U.S. Dollars (US$25,000,000)] (the " ProGas Payment Cap "); provided, however, if the Base Termination Payment exceeds the ProGas Payment Cap, then:

(1) ProGas shall notify NEA, concurrently with providing documentation of its calculation of the amounts in Section 3.2(b) above, of whether ProGas agrees to waive the ProGas Payment Cap and pay to NEA the ProGas Termination Payment in the amount of the Base Termination Payment, or

(2) If ProGas' notice provided for in Section 3.2(b)(1) states that ProGas declines to accept the election described in Section 3.2(b)(1), then within one (1) Business Day of receipt of such notice, NEA shall notify ProGas as to whether NEA elects to accept payment of the ProGas Termination Payment in the amount of the ProGas Payment Cap.

If ProGas declines to exercise its election under Section 3.2(b)(1) and NEA declines to accept its election under Section 3.2(b)(2), the Parties shall enter good-faith negotiations, for a period not to exceed two (2) Business Days from the date ProGas declines to exercise its waiver provided for in Section 3.2(b)2, during which time the Parties shall seek to arrive at a mutually acceptable ProGas Termination Payment. Notwithstanding the Parties' agreement to negotiate in good faith, ProGas shall not be obligated to make any ProGas Termination Payment exceeding the ProGas Payment Cap unless ProGas agrees to make such a payment in its sole discretion. If the Parties' good faith negotiations do not result in a mutually acceptable ProGas Termination Payment, within two (2) Business Days, then this Agreement shall terminate unless the parties mutually agree to extend period for good faith negotiations.

(c) If the Base Termination Payment is equal to zero, neither Party shall be obligated to make payment of a Termination Payment, and the Parties shall consummate the Closing as provided hereunder (subject to satisfaction of any remaining conditions precedent).

3.3 [RESERVED]

3.4 Determination of NYMEX Henry Hub Gas Prices . The monthly NYMEX Henry Hub Gas Prices used to calculate the NYMEX Reference Price have been determined and are set forth in Appendix A . The NYMEX Henry Hub Gas Prices used to determine the NYMEX Final Price shall be calculated as of the Termination Payment Calculation Date and shall be determined consistent with the methodology used to determine the NYMEX Reference Price as shown on Appendix A and as described below:

(a) Use of Visible Market .

(1) For each month in the Calculation Period for which Published Values exist, the NYMEX Henry Hub Gas Price shall be the Published Values for that month;

(2) For each month in the Calculation Period for which Published Values are not available, the Parties shall negotiate in good faith to agree upon stipulated values for the NYMEX Henry Hub Gas Price for such month. If the Parties cannot so agree within two (2) hours, then ProGas shall obtain, as promptly as commercially practicable and to the extent reasonably available, at least two (2) Broker Quotes for each NYMEX Henry Hub Gas Price for those months during the Calculation Period for which Published Values are not available and shall provide to NEA copies of all data, quotes and other information provided by the OTC Brokers in connection with such Broker Quotes. If Broker Quotes do not specify monthly prices for any given month during the Calculation Period, but do include Calendar Year Swap Spreads, then beginning with the first month for which no Published Value is available, the NYMEX Henry Hub Gas Price for such month shall be calculated as the sum of (i) the NYMEX Henry Hub Gas Price for the same month during the previous year plus (ii) the Calendar Year Swap Spread (such amount, the " Swap Spread-Derived Price " and such calculation, the " Swap Spread-Derived Price Calculation "). "Calendar Year Swap Spread" means the value quoted by an OTC Broker as a differential to the price of the Henry Hub natural gas futures contract for a given month and year. This calculation shall be repeated for any "stub" year (i.e., any year for which fewer than 12 months of monthly prices are available) until such year has a stipulated NYMEX Henry Hub Gas Price for each month during such year. The Swap Spread-Derived Price Calculation shall continue to be used, to the extent available, for subsequent monthly prices by adding the correlative year's Calendar Year Swap Spread for any given month to price for the same month during the prior year. For example, if the last month for which a Published Value is available is May 2009, then the June 2009 NYMEX Henry Hub Gas Price shall equal the June 2008 value plus the Calendar Year Swap Spread for June 2009. If Calendar Year Swap Spreads are not available for a given year and if any later Broker Quote provides the NYMEX Henry Hub Gas Price on a calendar year basis, then the monthly NYMEX Henry Hub Gas Price during each month of such calendar year for the annual Broker Quote shall be deemed to be the calendar year NYMEX Henry Hub Gas Price contained in the Broker Quote. All Broker Quotes obtained pursuant to this section shall be averaged, and Broker Quotes for any given NYMEX Henry Hub Gas Price (or Swap Spread-Derived Price) that are no greater than 105%, and no less than 95%, of the average of the Broker Quotes obtained for such NYMEX Henry Hub Gas Price (or Swap Spread-Derived Price) shall be " Eligible Broker Quotes " and all other Broker Quotes shall be disregarded for the purposes of this section. The arithmetic average of the Eligible Broker Quotes obtained for each NYMEX Henry Hub Gas Price for each month (or year or Swap Spread-Derived Price) shall be the NYMEX Henry Hub Gas Price for such month (or year or Swap Spread-Derived Price) for purposes of calculating the NYMEX Final Price.

(b) Absence of a Visible Market for Certain NYMEX Henry Hub Gas Prices . If neither Published Values nor Eligible Broker Quotes are available to determin
