          (b) Authorization; No Breach. The execution, delivery and performance of this Agreement has been duly authorized by such Seller. This Agreement constitutes a valid and binding obligation of such Seller, enforceable in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium, or other laws affecting creditors’ rights generally and limitations on the availability of equitable remedies. The execution and delivery by such Seller of this Agreement, and the fulfillment of and compliance with the terms hereof by such Seller, do not and shall not conflict with or result in a breach of the terms, conditions or provisions of, or require any authorization, consent, approval, exemption or other action by or notice to any court or administrative or governmental body pursuant to, its limited liability company operating agreement or any material law, statute, rule or regulation to which such Seller is subject, or any material agreement, instrument, order, judgment or decree to which such Seller is subject, except where any such condition would not have a material adverse effect on such Seller or its ability to perform its obligations hereunder. Such Seller has full right, power and authority to sell, assign, transfer and deliver the Repurchased Securities to be sold by such Seller hereunder.

          (c) Information. Such Seller has had an opportunity to ask questions and receive answers concerning the terms and conditions of the repurchase of Shares and Warrants pursuant hereto and has had full access to such other information concerning the Company and its subsidiaries as it has requested.

          (a) Authorization; No Breach. The execution, delivery and performance of this Agreement has been duly authorized by the Company. This Agreement constitutes a valid and binding obligation of the Company, enforceable in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium, or other laws affecting creditors’ rights generally

and limitations on the availability of equitable remedies. The execution and delivery by the Company of this Agreement, and the fulfillment of and compliance with the respective terms hereof by the Company, do not and shall not conflict with or result in a breach of the terms, conditions or provisions of, or require any authorization, consent, approval, exemption or other action by or notice to any court or administrative or governmental body pursuant to, its certificate of incorporation or bylaws or any material law, statute, rule or regulation to which the Company is subject, or any material agreement, instrument, order, judgment or decree to which the Company or any subsidiary is subject, except where any such condition would not have a material adverse effect on the Company or its ability to perform its obligations hereunder.

7.      Termination. In the event that the FERC approval is not obtained within the time periods prescribed in the Purchase/Placement Agreement and the Common Stock sold pursuant thereto is redeemed by the Company, then this Agreement shall terminate automatically and the Company shall promptly thereafter return all certificates representing Shares and/or Warrants to the holders thereof. Upon termination, this Agreement will forthwith become void and there will be no liability on the part of any party hereto to any other party hereto or its stockholders or directors or officers in respect thereof, except that the provisions of this Section 7 shall continue in full force and effect.

8.      General Provisions.

          (a) Survival of Representations. All representations and warranties contained herein or made in writing by any party in connection herewith shall survive the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby, regardless of any investigation made by a party or on its behalf.

          (b) Expenses. The parties will each pay their own costs and expenses (including attorneys’ fees and expenses) incurred in connection with the preparation, negotiation and consummation of this Agreement and the transactions contemplated hereby.

          (c) Severability. Whenever possible, each provision of this Agreement will 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 will not affect any other provision or any other jurisdiction, but this Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

          (d) Counterparts. This Agreement may be executed simultaneously in two or more counterparts, any one of which need not contain the signatures of more than one party, but all such counterparts taken together shall constitute one and the same Agreement.

          (e) Successors and Assigns. Except as otherwise provided herein, this Agreement shall bind and inure to the benefit of and be enforceable by any of the parties hereto and their respective successors and assigns (including subsequent holders of Shares).

          (f) Descriptive Headings; Interpretation. The descriptive headings of this Agreement are inserted for convenience only and do not constitute a part of this Agreement. The use of the word “including” in this Agreement shall be by way of example rather than by limitation.

          (g) Choice of Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to any choice of law or conflict of law rules or

provisions (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

          (h) WAIVER OF TRIAL BY JURY. EACH OF THE PARTIES TO THIS AGREEMENT IRREVOCABLY AND UNCONDITIONALLY WAIVERS THE RIGHT TO A TRIAL BY JURY IN ANY ACTION, SUIT OR PROCEEDING ARISING OUT OF, CONNECTION WITH OR RELATING TO THIS AGREEMENT, THE MATTERS CONTEMPLATED HEREBY, OR THE ACTIONS OF THE PARTIES IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT OF THIS AGREEMENT.

          (i) Remedies. Each of the parties to this Agreement will be entitled to enforce its rights under this Agreement specifically, to recover damages and costs (including attorneys’ fees) caused by any breach of any provision of this Agreement and to exercise all other rights existing in its favor. The parties hereto agree and acknowledge that money damages may not be an adequate remedy for any breach of the provisions of this Agreement and that any party in its sole discretion may apply to any court of competent jurisdiction (without posting any bond or deposit) for specific performance and/or other injunctive relief in order to enforce or prevent any violations of the provisions of this Agreement.

          (j) Amendment and Waiver. The provisions of this Agreement may be amended and waived only with the prior written consent of the parties hereto.
