8.3Conduct of Indemnification Proceedings.Promptly after receipt by any Indemnified Person of notice of any demand, claim or circumstances which would or might give rise to a claim or the commencement of any action, proceeding or investigation in respect of which indemnity may be sought pursuant to Section 8.2, such Indemnified Person shall promptly notify the Companies in writing and the Companies shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Person, and shall assume the payment of all fees and expenses; provided, however,that the failure of any Indemnified Person so to notify the Companies shall not relieve the Companies of its obligations hereunder except to the extent that the Companies are materially prejudiced by such failure to notify.  In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless: (i) such Company and the Indemnified Person shall have mutually agreed to the retention of such counsel; or (ii) in the reasonable judgment of counsel to such Indemnified Person representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them.  The Companies shall not be liable for any settlement of any proceeding effected without its written consent, which consent shall not be unreasonably withheld, but if settled with such consent, or if there be a final judgment for the plaintiff, the Companies shall indemnify and hold harmless such Indemnified Person from and against any loss or liability (to the extent stated above) by reason of such settlement or judgment.  Without the prior written consent of the Indemnified Person, which consent shall not be unreasonably withheld, the Companies shall not affect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Person from all liability arising out of such proceeding.

9.11Further Assurances.  The parties hereto shall execute and deliver all such further instruments and documents and take all such other actions as may reasonably be required to carry out the transactions contemplated hereby and to evidence the fulfillment of the agreements herein contained.

9.12Governing Law; Consent to Jurisdiction; Waiver of Jury Trial; Damages.

(a)This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of Texas without regard to the choice of law principles thereof.  Each of the parties hereto irrevocably submits to the exclusive jurisdiction of the courts of the State of Texas located in Harris County and the United States District Court for the Southern District of Texas for the purpose of any suit, action, proceeding or judgment relating to or arising out of this Agreement and the transactions contemplated hereby.  Service of process in connection with any such suit, action or proceeding may be served on each party hereto anywhere in the world by the same methods as are specified for the giving of notices under this Agreement.  Each of the parties hereto irrevocably consents to the jurisdiction of any such court in any such suit, action or proceeding and to the laying of venue in such court.  Each party hereto irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.

(b)THE COMPANIES, THE ADMINISRATIVE AGENT AND EACH INVESTOR EXPRESSLY AND IRREVOCABLY WAIVE, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY ACTION AGAINST ANOTHER PARTY, ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES.

9.13Remedies Cumulative.  No failure or delay on the part of the Administrative Agent or the Investors in exercising any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy.  The remedies provided for herein and in the other Transaction Documents are cumulative and are not exclusive of any remedies that may be available to the Administrative Agent or the Investors at law, in equity or otherwise.

9.14Usury Savings.  Specific reference is made to Section 15 of each Note.

9.15Effect of Conversion.  Notwithstanding anything herein or in any other Transaction Document to the contrary, if any Investor converts the entire amount of the indebtedness owed to it under its Note pursuant to the terms of its Note, or such indebtedness is otherwise converted pursuant to the terms of any other Transaction Document, then (i) upon such conversion, the indebtedness under such Note shall be paid and satisfied in full, (ii) such Investor will be deemed to no longer be a party to any of the Transaction Documents or retain any rights thereunder (except for rights that survive termination, including indemnity rights), and (iii) the Administrative Agent shall no longer act as Administrative Agent, including under and pursuant to the Intercreditor Agreement, for such Investor for any purpose.  For avoidance of doubt, any Investor may convert some, but not all, of the indebtedness owed to it under its Note pursuant to the terms of its Note and continue to remain a party to, and without affecting the enforceability of, the Transaction Documents to which such Investor is a party.

9.16Reinstatement.  Notwithstanding anything in any Transaction Document to the contrary, if at any time, any Pledge Agreement, the ancillary documents related thereto, any attendant rights and benefits thereto or thereunder or the Collateral thereunder (collectively, the “Pledge and Collateral Rights”), on the one hand, or any Assignment, the ancillary documents related thereto or any attendant property rights and benefits thereunder (collectively, the “Assignment and Ownership Rights”), on the other hand, are revoked, rescinded, invalidated, or are otherwise determined to be null and void or must otherwise be restored or returned to Gulf, as determined by a court of competent jurisdiction under any applicable law, then (i) with respect to any such determination with regard to any Pledge and Collateral Rights, and without the need of any action, consent or approval by the Companies, the Administrative Agent or any Investor, the Assignment and Ownership Rights and any other Transaction Documents related thereto (including, without limitation, the Purchase Agreement, the Notes and the Guaranties) shall be fully and automatically reinstated, and all Assignment and Ownership Rights and such Transaction Documents shall be in full force and effect, and (ii) with respect to any such determination with regard to any Assignment and Ownership Rights, and without the need of any action, consent or approval by the Companies, the Administrative Agent or any Investor, the Pledge and Collateral Rights and any other Transaction Documents related thereto (including, without limitation, the Purchase Agreement, the Notes and the Guaranties) shall be fully and automatically reinstated and all Pledge and Collateral Rights and such Transaction Documents shall be in full force and effect.  In the event that any of the foregoing documents are deemed to be reinstated after any such document has been terminated and released by the Administrative Agent, the termination and release shall be deemed not to have occurred, and such documents shall be reinstated and shall be in full force and effect as if such documents had never been terminated or released.  If any of the foregoing documents have been returned to any Company, such Company shall promptly deliver such documents to the Administrative Agent and the Investors or the Administrative Agent may provide such Company with a copy of such documents and such Company shall promptly execute and deliver a copy of any such documents to the Administrative Agent.

9.17Investor Decisions.  Each Investor acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Investor and based on the Companies’ financial statements and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the other Transaction Documents.  Each Investor also acknowledges that it shall, independently and without reliance upon the Administrative Agent or any other Investor and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Transaction Documents.  For avoidance of doubt, each Investor further acknowledges that it has, to the extent it deems necessary, independently and without reliance upon legal counsel for the Administrative Agent or any other Investor, obtained its own legal counsel regarding the Transaction Documents and transactions related thereto.

9.18Controlling Agreement.  With respect solely to the relative rights and obligations of the Administrative Agent and the Investors, and not with respect to any right or obligation of the Companies under any Transaction Document, in the event of any conflict between the provisions of this Agreement and the provisions of the Intercreditor Agreement, the provisions of the Intercreditor Agreement shall govern and control.
