NOW, THEREFORE, in consideration of the promises and of the mutual commitments and obligations hereinafter set forth, the parties hereto hereby agree as follows: 2 SECTION 1. Definitions. As used herein, the following terms shall have the following meanings: "Auction" means the attempted sale of a Facility or Facilities pursuant to which the owner of the Facility or Facilities has stated or announced that it intends to have or is having discussions, for the purpose of soliciting a bid or bids, with respect to such sale of the Facility or Facilities, or interests therein with more than one potential buyer. "Affiliate" shall mean, with respect to any Person, any other Person directly or indirectly controlling or controlled by or under direct or indirect common control with such specified Person. "Facility" means an electric generating facility in the United States or Canada that, at the time of any purchase or attempted purchase, is either fully constructed or has, or has previously had, commercial operations. "Greenfield Project" means a project to construct a new electric generating facility in the United States or Canada when the interest to be acquired is acquired prior to one hundred thirty five (135) days after the date of commercial operation. "IPO" means an underwritten offering or series of underwritten offerings pursuant to which the common stock, par value $.01 per share ("Common Stock") of the Company, becomes registered under Section 12 of the Securities Exchange Act of 1934, as amended (the "Exchange Act") (a) in which either (i) the Common Stock issued in such IPO constitutes at least 20% of the Common Stock or (ii) the gross proceeds to the Company and any selling stockholders, in the aggregate, is at least $75 million before deducting underwriting discounts, commissions and offering expenses and (b) which results in the Common Stock being held by at least 500 holders of record within the meaning of Rule 12g5-1 under the Exchange Act. "Negotiated Transaction" shall have the meaning set forth in Section 4. "Person" means any individual, corporation, limited liability company, limited or general partnership, joint venture, association, joint-stock company, trust, unincorporated organization, other entity or government or any agency or political subdivisions thereof. SECTION 2. Term. The term of this Agreement shall be from the date hereof until the earlier to occur of (i) the closing of an IPO, (ii) six months after the date on which all TEPCO International Group representatives or nominees have ceased to hold any of the following positions of the Company: director, observer, officer or employee, (iii) the liquidation of the Company, and (iv) five years after the date hereof. SECTION 3. Auctions. With respect to a Facility which is the subject of an Auction, the TEPCO International Group shall be prohibited from bidding, and shall - 2 - 3 not bid, or take any steps with the seller of the Facility or any other third party to materially further the acquisition of such Facility, or any interest therein ("Acquisition Actions"), unless the Company provides the TEPCO International Group with prior written notice that the TEPCO International Group may take Acquisition Actions with respect to such Facility (the "Granting Notice"). Any Granting Notice shall be given by the Company in the sole discretion of the Company and under no circumstance shall the Company be under an obligation to provide a Granting Notice. If the Company provides to the TEPCO International Group a Granting Notice with respect to a Facility, the TEPCO International Group may take any and all Acquisition Actions with respect to such Facility. The Company may, but shall be under no obligation to, proceed with Acquisition Actions with respect to a Facility for which it did not provide a Granting Notice. SECTION 4. Negotiated Transactions. If the TEPCO International Group wishes to take Acquisition Actions with respect to a Facility (the "Subject Facility") which is not the subject of an Auction (any transaction, or attempted transaction, to acquire any such Facility, or an interest therein, is referred to as a "Negotiated Transaction"): (i) the TEPCO International Group shall provide, in good faith, taking into account all relevant facts and circumstances, the Company with written notice (a "Facility Notice") including (a) the identity of the Subject Facility, (b) a statement that the TEPCO International Group, subject to this Section 4, intends to take Acquisition Actions to purchase such Subject Facility, or an interest therein, and (c) a statement that the TEPCO International Group believes it has a reasonable probability of acquiring such Subject Facility, or an interest therein, in such Negotiated Transaction. The Company shall provide a written response (a "Response") to any and all Facility Notices, which Response shall indicate whether or not the Company intends to take Acquisition Actions with respect to the purchase of the Subject Facility, or an interest therein (a Response stating that the Company does not have such intention is referred to as a "No Intention Response"). Such Response shall be given in good faith, taking into account all relevant facts and circumstances, within sufficient time (a "Response Period") to allow the TEPCO International Group, if a No Intention Response is given, to pursue, on a commercially reasonable basis, the purchase of such Subject Facility, or an interest therein, in the Negotiated Transaction. Prior to the receipt of a Response to a Facility Notice, the TEPCO International Group shall take no Acquisition Actions with respect to the Subject Facility. (ii) In the event the Company indicates in a Response that it intends to take Acquisition Actions with respect to the purchase of the Subject Facility, or an interest therein, through a Negotiated Transaction (a "Positive Response"), the TEPCO International Group shall be precluded from taking any Acquisition Actions with respect to the Subject Facility; provided, however, that in the event that the Company, after - 3 - 4 initially giving a Positive Response with respect to the purchase of such Subject Facility, or an interest therein, subsequently decides not to pursue such purchase, the Company shall promptly provide a No Intention Response to the TEPCO International Group with respect to such Subject Facility. If the Company gives a No Intention Response, the TEPCO International Group shall have the right to take Acquisition Actions with respect to the purchase of the Subject Facility, or an interest therein. (iii) In the event that, during negotiations with respect to a Negotiated Transaction, the seller of the Subject Facility commences an Auction, the provisions of Section 3 shall apply to such Subject Facility, and the TEPCO International Group shall immediately terminate any Acquisition Actions with respect to such Subject Facility unless a Granting Notice is given with respect to such Subject Facility. SECTION 5. Excluded Assets. Notwithstanding the foregoing, the TEPCO International Group shall have the right to take Acquisition Actions, with respect to (i) any interest in an existing Facility owned by the TEPCO International Group as of the date of this Agreement, (ii) to a Greenfield Project and (iii) any interest in a Facility in which TEPCO International and a Person identified in a separate letter between the Company and TEPCO International dated the date hereof, have a joint investment, whether before or after the date of this Agreement.

Amendment and Waiver. No modification, amendment or waiver of any provision of this Agreement shall be effective against any party unless such modification, amendment or waiver is approved in writing by such party.

SECTION 9. Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or any other jurisdiction, but this Agreement shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.
