WITNESSETH:

WHEREAS, Sellers collectively own a 50% partnership interest in Iroquois Gas Transmission System, L.P., a Delaware limited partnership ("Iroquois"), comprising a 21% limited partner interest owned by TCPL, a 4% limited partner interest owned by TCIL, and a 25% general partner interest owned by TCIL;

WHEREAS, Buyer desires to purchase and acquire, and Sellers desire to sell and assign, a 49.34% partnership interest in Iroquois, comprising the entire 21% limited partner interest held by TCPL, the entire 25% general partner interest held by TCIL, and a 3.34% limited partner interest held by TCIL (collectively, the "Iroquois Interest") pursuant to the terms and conditions set forth in this Agreement;

WHEREAS, concurrently with the execution of this Agreement, Sellers and Buyer are entering into an Option Agreement that provides, among other things, that Buyer has the option to acquire TCIL's remaining 0.66% limited partner interest in Iroquois, on the terms and subject to the conditions set forth therein;

WHEREAS, the Conflicts Committee (the "Conflicts Committee") of the Board of Directors of the General Partner (as defined herein) has (i) received an opinion of Evercore Group L.L.C., the financial advisor to the Conflicts Committee (the "Partnership Financial Advisor"), that the aggregate consideration to be paid by the Partnership (as defined herein) in connection with the transactions contemplated hereby and under the PNGTS Agreement (as defined herein) is fair to the Partnership and its common unitholders (other than the General Partner (as defined herein) and its Affiliates (as defined herein)) from a financial point of view, (ii) determined that the Transaction Agreements (as defined herein) and the transactions contemplated thereby are fair and reasonable to, and in the best interests of, the MLP and the common unitholders of the MLP (other than the General Partner and its Affiliates), (iii) granted "Special Approval" with respect to the transactions contemplated by the Transactions Agreements on the terms and conditions set forth therein, and (iv) recommended that the Board of Directors of the General Partner approve the Transaction Agreements and the transactions contemplated thereby; and

WHEREAS, the Board of Directors of the General Partner has approved the Transaction Agreements and transactions contemplated thereby.

NOW, THEREFORE, in consideration of the premises and the mutual covenants herein, and for other good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, the Parties, intending to be legally bound, hereby agree as follows:

ARTICLE I
SALE AND PURCHASE

Section 1.01 Agreement to Sell and to Purchase Iroquois Interest.

At the Closing, and on the terms and subject to the conditions set forth in this Agreement, Sellers shall sell, assign and deliver to Buyer, and Buyer shall purchase and accept from Sellers, the Iroquois Interest.

Section 1.02 Purchase Price.

The purchase price to be paid by Buyer to Sellers for the Iroquois Interest (the "Purchase Price") shall equal the Closing Payment, as adjusted in accordance with Section 1.03.

Section 1.03 Working Capital Adjustment.

(a) Within ninety (90) days after the Closing, Sellers shall prepare and deliver to Buyer a written statement (the "Working Capital Adjustment Statement"), together with supporting work papers with respect to the calculation of the amounts set forth therein, which reflects the Working Capital as of the Effective Time for Iroquois. Buyer agrees to cooperate with Sellers in connection with the preparation of the Working Capital Adjustment Statement and related information, and shall provide to Sellers and Sellers' representatives such books, records and information relating to Iroquois during normal business hours, as may be reasonably requested from time to time by Sellers or their representatives, to the extent Buyer has access thereto.

(b) Buyer may dispute the Working Capital Adjustment Statement and the items reflected therein; provided, however, that Buyer shall notify Sellers in writing of any disputed amounts, and provide a reasonably detailed description of the basis of such dispute, within ninety (90) days after Buyer's receipt of the Working Capital Adjustment Statement. In the event of such a dispute, the Parties shall attempt to reconcile their differences and any resolution by them as to any disputed amounts shall be final, binding and conclusive on the Parties. If the Parties are unable to reach a resolution of any such differences within ninety (90) days after Sellers' receipt of Buyer's written notice of dispute, the Parties shall submit the amounts remaining in dispute for determination and resolution to the Independent Accounting Firm, which shall be instructed to determine and report to the Parties, within ninety (90) days after such submission, a resolution of such remaining disputed amounts, and such resolution shall be final, binding and conclusive on the Parties with respect to the remaining amounts disputed. The Independent Accounting Firm shall only resolve the disputed amounts by choosing the amounts submitted by Buyer or Sellers or amounts in between. The fees and disbursements of the Independent Accounting Firm shall be shared as to 50% by Buyer, on the

(c) one hand, and 50% by Sellers, on the other hand. For the avoidance of doubt, the Working Capital Adjustment Statement and the amounts reflected thereon shall be deemed to be modified to the extent of any changes thereto that become final, binding and conclusive on the Parties based on mutual agreement or a determination of the Independent Accounting Firm in accordance with this Section 1.03(b).

(d) Within five (5) Business Days after the earliest to occur of (i) a mutual written agreement of the Parties with respect to the Working Capital Adjustment Statement (ii) the termination of the ninety (90) day period described in Section 1.03(b) if Buyer does not provide a notice of dispute within such period as provided therein and (iii) the final determination of all such disputed amounts in accordance with Section 1.03(b) (the "Working Capital Adjustment Period"), (A) if Working Capital as of the Effective Time exceeds the Estimated Working Capital, Buyer shall pay Sellers 49.34% of the amount of such excess, and (B) if Working Capital as of the Effective Time is less than the Estimated Working Capital, Sellers shall pay to Buyer 49.34% of the amount of such deficiency. All payments made pursuant to the previous sentence shall be paid together with interest thereon at a rate of 2.5% per annum, calculated daily, for the period commencing on the Effective Time through the date of payment, in cash by wire transfer of immediately available funds.

(e)

(i) Notwithstanding the foregoing, if the Distribution Agreement has not been executed by all parties thereto on or before the Closing Date, the Estimated Surplus Cash will be excluded from the calculation of Estimated Working Capital for purposes of determining the Closing Payment, and (subject to clause (ii), below) Actual Surplus Cash will be excluded from the calculation of Working Capital for purposes of determining the excess amount (if any) that Buyer would otherwise be required to pay within the period described in Section 1.03(c).

(ii) If, after the Closing Date but before the end of the Working Capital Adjustment Period, the Distribution Agreement is executed by all parties thereto, then an amount equal to Actual Surplus Cash will be included in the calculation of Working Capital for purposes of determining the amount of any payment to be made by Sellers or Buyer, as applicable, pursuant to Section 1.03(c).

(iii) In the event the Distribution Agreement is executed after the Working Capital Adjustment Period, then within 30 days of the execution of the Distribution Agreement, Buyer shall pay to Sellers an amount equal to 49.34% of the Actual Surplus Cash.

(iv) If the Distribution Agreement has not been executed by the parties prior to the fifth anniversary of the Closing Date, then on such date Buyer shall pay to Sellers an amount equal to 49.34% of the Actual Surplus Cash.

(v) All payments made pursuant to this Section 1.03(d) shall be paid together with interest thereon at a rate of 2.5% per annum, calculated daily, for the period commencing on the Closing Date through the date of payment, in cash by wire transfer of immediately available funds.

(b) Claims. An Indemnified Party that seeks indemnification under this Article VI for a Loss and Expense that does not arise out of a Third Party Claim (such claim for indemnification being referred to herein as a "Claim") shall promptly notify the Indemnifying Party of such Claim in writing. Such notice shall be a condition precedent to any liability of the Indemnifying Party for such Claim under this Article VI, and such notice shall describe the Claim in reasonable detail and shall indicate the amount (estimated if necessary) of the Loss and Expense that has been or may be sustained by the Indemnified Party.

(c) Third Party Claims. In the event that any of the Indemnified Parties is made or threatened to be made a defendant in or party to any action or proceeding, judicial or administrative, instituted by any third party, the liabilities for which, or the costs or expenses of which, are or would be a Loss and Expense for which the Indemnified Party is entitled to indemnification hereunder (any such third party action or proceeding being referred to herein as a "Third Party Claim"), the Notifying Party shall give the Indemnifying Party notice in writing, within ten (10) calendar days after learning of such Third Party Claim. The failure to timely give such notice shall not affect any Indemnified Party's ability to seek reimbursement except to the extent such failure adversely affects the Indemnifying Party's ability to defend successfully a Third Party Claim or such notice is given after the expiration of the applicable survival period set forth in Section 6.01.

Such contest and defense shall be conducted by competent counsel employed by the Indemnifying Party and reasonably acceptable to the Notifying Party. The Notifying Party shall be entitled at any time, at its own cost and expense (which expense shall not constitute a Loss and Expense) to participate in such contest and defense and to be represented by attorneys of its or their own choosing. If the Notifying Party elects to participate in such defense, the Notifying Party shall cooperate with the Indemnifying Party in the conduct of such defense. Neither the Notifying Party nor the

(d) Indemnifying Party may concede, settle or compromise any Third Party Claim without the consent of the other Party, which consent shall not be unreasonably withheld or delayed. Subject to the preceding sentence, in the event the Indemnifying Party fails to contest and defend a Third Party Claim, the Notifying Party shall be entitled to contest and defend such Third Party Claim in such manner and on such terms as the Notifying Party may deem appropriate, and the Indemnifying Party shall be liable for the Loss and Expense of the Notifying Party in accordance with the provisions of this Article VI.

Section 6.05 Limitations.

The foregoing limitations shall not apply to any Loss and Expense (A) resulting from or arising out of a breach of a Fundamental Representation, or (B) relating to Seller Taxes.

(c) Maximum Indemnification Liability of Sellers.
