SCHEDULE   I





1.          The Client agrees to defend, indemnify, and hold the Firm and its successors, agents and employees harmless from and against any losses, claims, damages, or liabilities (including, without limitation, court costs and reasonable attorneys fees) to which the Firm and its successors, agents and employees may be come subject insofar as the same arises from an action which alleges or is based upon the alleged untrue statement of a material fact, or omission of a material fact, or any other violation of applicable securities or other laws, irrespective of the role or concurrent negligence of the Firm and its successors, agents and employees, by the Client or its officers, directors, agents, employees, and controlling persons and to reimburse the Firm for any legal or other expenses reasonably incurred by it in connection with
investigating, settling, or defending any action or claim in connection therewith (including, without limitation, court costs and reasonable attorneys fees); provided, however, that the Client shall not be liable in any such case to the extent that any such loss, claim, damage, or liability is found in a final judgment of a court of competent jurisdiction to have resulted from the Firms gross negligence or bad faith in performing his services hereunder. If for any reason the foregoing indemnification is unavailable to us or insufficient to hold us harmless, then you shall contribute to the amount paid or payable by us as a result of such loss, claim, damage, or liability in such proportion as is appropriate to reflect not only the relative benefits received by you on the one hand and us on the other hand but also the relative fault of you and us, as well as any relevant equitable considerations.



2.         With respect to the foregoing Paragraph 1 of the indemnification, the Client agrees that the Firm and its successors, agents and employees shall not be deemed to have been grossly negligent for reasonably relying upon any written untrue statement or alleged omission of a material fact necessary to make the statements, in light of the circumstances in which made, not misleading, contained in or omitted from any information provided to the Firm by or on behalf of the Client (including, without limitation of the generality of the foregoing, any accountant or attorney employed or retained by the Client).



3.         The Client agrees to reimburse to the Firm at Houston, Texas within ten days after presentation of any statement by the Firm, all reasonable expenses(including, without limitation of the generality of the foregoing, fees and expenses of attorneys selected by the Firm but who are not unacceptable to the Client) incurred in connection with any testimony he or his employees are required to give (in court, before a regulatory agency, by deposition, or otherwise) in any regulatory or court proceeding (including depositions), whether or not the Firm is a party, and which related directly or indirectly to the proposed Project.



4.         The Firm agrees that, in the event any action (with respect to which indemnity or reimbursement from the Client may be sought by the Firm on account of agreements contained herein) shall be brought or threatened against the Firm, prompt notice will be given to the Client in writing of such action, together with a copy of all papers served on, or received by, the Firm in connection with such action; provided that failure to give such notice shall not affect the Firms

right under these indemnification provisions, unless, and only to the extent that, such failure results in the Clients forfeiture of substantive rights or defenses. If such an event occurs, the Client shall assume the defense of such action, including the employment of counsel and the payment of all expenses, the Firm and his heirs, successors, agents and employees shall have the right to employ separate counsel in any such action and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the Firm, his heirs, successors, agents and employees unless (a) the employment thereof has been specifically authorized by the Client in writing; (b) the Client has failed to assume the defense and employ counsel; or (c) the named parties or parties threatened to be named, to any such action (including any impeded parties or parties threatened to be impeded)
include both the Firm, his heirs, successors, agents and employees and the Client and the Firm, his heirs, successors, agents and/or employees, have been advised by such counsel that there may be one or more legal defenses available to it/them which are different from or additional to those available to the Client (in which cases the Firm, and his heirs, successors, agents and employees shall have the right to employ his/their own counsel and in such cases any reasonable fees and expenses of such counsel shall be paid by the Client).
