(the "Act"), for the regulation and management of the Company.

1.      Name.    The name of the limited liability company is Toro Partner LLC (the "Company").

4.      Principal Office.    The principal office of the Company (at which the books and records of the Company shall be maintained) shall be at such place as the Board of Managers may designate, which need not be in the State of Delaware. The Company may have such other offices as the Board of Managers may designate.

5.      Member.

     (a)      The term "Member" as used in this Agreement means Upstate Energy, in its capacity as a member (as defined in the Act) of the Company, and any person hereafter admitted to the Company as a member, but such term does not include any person who has ceased to be a member of the Company. The name and the mailing address of the initial Member is as follows:

	Upstate Energy Inc.
	▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇
	▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇

6.      Powers.    The Company shall have the power and authority to take any and all actions necessary, appropriate, proper, advisable, convenient or incidental to or for the furtherance of the purposes set forth in Section 2, including any and all powers set forth in the Act.

7.      Term.    The term of the Company commenced on the date of the filing of the Certificate of Formation in the Office of the Secretary of the State of Delaware and shall be perpetual, unless it is dissolved sooner as a result of: (a) the written election of the Member, (b) the entry of a decree of judicial dissolution under Section 18-802 of the Act, or (c) the occurrence of an event that causes there to be no members of the Company, unless the Company is continued in accordance with the Act.

9.      Distributions.      The Company shall make cash distributions to the Member at such times and in such amounts as may be determined by the Board of Managers. The Company may make non-cash distributions to the Member at such times and in such forms as may be determined by the Board of Managers. Notwithstanding any other provision of this Agreement, neither the Company, nor the Manager on behalf of the Company, shall make a distribution to the Member if such distribution would violate the Act or other applicable law.

10.      Management.    Subject to the provisions of the Act and any limitations in this Agreement as to action to be authorized or approved by the Member, all management powers over the business and affairs of the Company shall be exclusively vested in a board of managers (the "Board of Managers"), comprised of a number of individuals (not less than 2) (each, a "Manager") determined by the Member and each of whom shall be appointed by the Member. Collectively, the Managers shall constitute "managers" of the Company within the meaning of the Act. The Board of Managers may delegate certain of its powers to officers (the "Officers"), who shall be agents of the Company. Except as otherwise specifically provided in this Agreement, the authority and functions of the Board of Managers and of the Officers shall be identical to the authority and functions of the board of directors and officers, respectively, of a corporation organized under the Delaware General Corporation Law. Thus, except as otherwise specifically provided in this Agreement, the business and affairs of the Company shall be managed under the direction of the Board of Managers, and the day-to-day activities of the Company shall be conducted on the Company's behalf by the Officers. In addition to the powers that now or hereafter may be granted to managers under the Act and to all other powers granted under any other provision of this Agreement, the Board of Managers (subject to Section 11 of this Agreement) and the Officers (subject to Section 12 of this Agreement and the direction of the Board of Managers) shall have full power and authority to do all things on such terms as they, in their sole discretion, may deem necessary or appropriate to conduct, or cause to be conducted, the business and affairs of the Company. The Member, by virtue of its status of a member of the Company, shall not have any management power over the business and affairs of the Company or actual or apparent authority to enter into contracts on behalf of, or to otherwise bind, the Company.

11.      Board of Managers.

     (a)      Election and Removal of Managers.    Upon election by the Member, each Manager shall hold office until death, disability, resignation or removal at any time at the pleasure of the Member. If a vacancy occurs on the Board of Managers, the Member shall elect a successor so that the Board of Managers remains fully constituted at all times.

     (b)      Meetings and Approval Requirements.

          (i)      Regular Meetings.    Regular meetings of the Board of Managers shall be held as the Board of Managers may determine and, if so determined, no notice thereof need be given. Special meetings of the Board of Managers shall be held at the written request of any Manager.

          (ii)      Telephonic Meetings.    Any meeting of the Board of Managers may be held by conference telephone call or through similar communications equipment by means of which all persons participating in the meeting are able to hear each other.

In the case of actions taken at a meeting, the affirmative vote of at least a majority of the Managers present in person or by electronic means, as the case may be, and voting at a duly held meeting of the Board of Managers where a quorum is present shall be necessary for any action of the Board of Managers.

          (vi)      Written Consents.    Any action required or permitted to be taken at a meeting of the Board of Managers may be taken without a meeting, without prior notice and without a vote if a consent or consents in writing, setting forth the action so taken, shall be signed by at least a majority of the Managers. Such consents shall be filed with the minutes of the proceedings of the Board of Managers.

          (vii)      Compensation and Reimbursement.    Except as determined by the Board of Managers, no compensation or fees shall be paid by the Company to any individual for serving as a Manager.
