Section 3.02 Defend Title. This Deed of Trust is, and always will be kept, a direct first priority Lien upon the Collateral; provided that Permitted Liens may exist as provided in the Collateral Agency Agreement, but no intent to subordinate the priority of the Liens created hereby is intended or inferred by such existence.

If (i) an adverse claim be made against or a cloud develop upon the title to any part of the Collateral other than a Permitted Lien or (ii) any Person, including the holder of a Permitted Lien, shall challenge the priority or validity of the Liens created by this Deed of Trust, then the Mortgagor agrees to immediately defend against such adverse claim, take appropriate action to remove such cloud or subordinate such Permitted Lien, in each case, at the Mortgagor’s sole cost and expense. The Mortgagor further agrees that the Mortgagee may take such other action as it reasonably deems advisable to protect and preserve its interest in the Collateral, and in such event the Mortgagor will indemnify the Mortgagee against any and all cost, attorneys’ fees and other expenses which they may incur in defending against any such adverse claim or taking action to remove any such cloud.

Section 3.03 Not a Foreign Person. The Mortgagor is not a “foreign person” within the meaning of sections 1445 and 7701 of the Internal Revenue Code of 1986, as amended (i.e., the Mortgagor is not a non-resident alien, foreign corporation, foreign partnership, foreign trust or foreign estate as those terms are defined in such Code and any regulations promulgated thereunder).

The Mortgagor will not sell, lease, assign, transfer or otherwise dispose or abandon any of the Collateral before the Release Date except (i) for the sale, assignment, transfer and disposition of Hydrocarbons in the ordinary course of business, (ii) as consented to by a Dual-Vote Majority and/or (iii) as otherwise contemplated by this Deed of Trust.

Section 3.06 Failure to Perform. The Mortgagor agrees that if it fails to perform any act or to take any action which it is required to perform or take hereunder or pay any money which the Mortgagor is required to pay hereunder, the Mortgagee, in the Mortgagor’s name or its own name, may, but shall not be obligated to, perform or cause to perform such act or take such action or pay such money, and any expenses so incurred by it and any money so paid by it shall be a demand obligation owing by the Mortgagor to the Mortgagee, and the Mortgagee, upon making such payment, shall be subrogated to all of the rights of the Person receiving such payment.

The Mortgagor hereby irrevocably appoints the Trustee and the Mortgagee, with full power of substitution, to each be the Mortgagor’s attorney-in-fact and in the name and on behalf of the Mortgagor, at any time after the occurrence and during the continuance of an Event of Default, to execute and deliver any deeds, transfers, conveyances, assignments, assurances and notices which the Mortgagor ought to execute and deliver and

If the Trustee or the Mortgagee shall have given notice of sale hereunder, any successor or substitute trustee thereafter appointed may complete the sale and the conveyance of the property pursuant thereto.

Section 4.04 Judicial Foreclosure; Receivership. If any of the Secured Obligations shall become due and payable and shall not be promptly paid, the Mortgagee shall have the right and power to proceed by a suit or suits in equity or at law, whether for the specific performance of any covenant or agreement herein contained or in aid of the execution of any power herein granted, or for any foreclosure hereunder or for the sale of the Collateral under the judgment or decree of any court or courts of competent jurisdiction, or for the appointment of a receiver pending any foreclosure hereunder or the sale of the Collateral under the order of a court or courts of competent jurisdiction or under executory or other legal process, or for the enforcement of any other appropriate legal or equitable remedy. Any money advanced by the Mortgagee in connection with any such receivership shall be a demand obligation (which obligation the Mortgagor hereby expressly promises to pay) owing by the Mortgagor to the Mortgagee and shall bear interest from the date of making such advance by the Mortgagee until paid at the Default Rate.

Section 4.05 Foreclosure for Installments. The Mortgagee shall also have the option to proceed with foreclosure in satisfaction of any installments of the Secured Obligations which have not been paid when due either through the courts or by directing the Trustee to proceed with foreclosure in satisfaction of the matured but unpaid portion of the Secured Obligations as if under a full foreclosure, conducting the sale as herein provided and without declaring the entire principal balance and accrued interest and other Secured Obligations then due; such sale may be made subject to the unmatured portion of the Secured Obligations, and any such sale shall not in any manner affect the unmatured portion of the Secured Obligations, but as to such unmatured portion of the Secured Obligations this Deed of Trust shall remain in full force and effect just as though no sale had been made hereunder. It is further agreed that several sales may be made hereunder without exhausting the right of sale for any unmatured part of the Secured Obligations, it being the purpose hereof to provide for a foreclosure and sale of the security for any matured portion of the Secured Obligations without exhausting the power to foreclose and sell the Deed of Trust Property for any subsequently maturing portion of the Secured Obligations.

Section 4.06 Separate Sales. The Collateral may be sold in one or more parcels and to the extent permitted by applicable law in such manner and order as the Mortgagee, in its sole discretion, may elect, it being expressly understood and agreed that the right of sale arising out of any Event of Default shall not be exhausted by any one or more sales.

Section 4.07 Possession of Deed of Trust Property. If an Event of Default shall have occurred and be continuing, then, to the extent permitted by applicable law, the Mortgagee shall have the right and power to enter into and upon and take possession of all or any part of the Collateral in the possession of the Mortgagor, its successors or assigns, or its or their agents or servants, and may exclude the Mortgagor, its successors or assigns, and all persons claiming under the Mortgagor, and its or their agents or servants wholly or partly therefrom; and, holding the same, the Mortgagee may use, administer, manage, operate and control the Collateral and conduct the business thereof to the same extent as the Mortgagor, its successors or assigns, might at the time do and may exercise all rights and powers of the Mortgagor, in the name, place and stead of the Mortgagor, or otherwise as the Mortgagee shall deem best. All costs, expenses and liabilities of every character incurred by the Mortgagee in administering, managing, operating, and controlling the Deed of Trust Property shall constitute a demand obligation (which obligation the Mortgagor hereby expressly promises to pay) owing by the Mortgagor to the Mortgagee and shall bear interest from the date of demand on Mortgagor therefor until paid at the Default Rate.

- 9 -

Section 4.08 Remedies Cumulative, Concurrent and Nonexclusive. Every right, power, privilege and remedy herein given to the Trustee or the Mortgagee shall be cumulative and in addition to every other right, power and remedy herein specifically given or now or hereafter existing in equity, at law or by statute. Each and every right, power, privilege and remedy whether specifically herein given or otherwise existing may be exercised from time to time and so often and in such order as may be deemed expedient by the Mortgagee, and the exercise, or the beginning of the exercise, or the abandonment, of any such right, power, privilege or remedy shall not be deemed a waiver of the right to exercise, at the same time or thereafter any other right, power, privilege or remedy. No delay or omission by the Trustee or Mortgagee or any other Secured Person in the exercise of any right, power or remedy shall impair any such right, power, privilege or remedy or operate as a waiver thereof or of any other right, power, privilege or remedy then or thereafter existing.

Section 4.09 Discontinuance of Proceedings. If the Trustee or the Mortgagee shall have proceeded to invoke any right, remedy or recourse permitted hereunder or under any Secured Document or available at law and shall thereafter elect to discontinue or abandon same for any reason, then it shall have the unqualified right so to do and, in such an event, the parties shall be restored to their former positions with respect to the Secured Obligations, this Deed of Trust, the Collateral Agency Agreement, the Collateral and otherwise, and the rights, remedies, recourses and powers of the Trustee and the Mortgagee, as applicable, shall continue as if same had never been invoked.

Section 4.10 No Release of Obligations. Neither the Mortgagor nor any other Person hereafter obligated for payment of all or any part of the Secured Obligations shall be relieved of such obligation by reason of: the failure of any Person so obligated to foreclose the Lien of this Deed of Trust or to enforce any provision hereunder or under the Collateral Agency Agreement or any other Secured Document; the release, regardless of consideration, of the Collateral or any portion thereof or interest therein or the addition of any other property to the Collateral; or by any other act or occurrence save and except upon the occurrence of the Release Date.

Section 4.11 Release of and Resort to Collateral. The Mortgagee may release, regardless of consideration, any part of the Collateral without, as to the remainder, in any way impairing, affecting, subordinating or releasing the Lien created in or evidenced by this Deed of Trust or its stature as a first and prior Lien in and to the Collateral and without in any way releasing or diminishing the liability of any Person liable for the repayment of the Secured Obligations. For payment of the Secured Obligations, the Mortgagee may resort to any other security therefor held by the Mortgagee or the Trustee in such order and manner as the Mortgagee may elect.

Section 4.12 Waiver of Redemption, Notice and Marshalling of Assets, Etc. To the fullest extent permitted by law, the Mortgagor hereby irrevocably and unconditionally waives and releases all benefits that might accrue to the Mortgagor by virtue of any present or future moratorium law or other law exempting the Collateral from attachment, levy or sale on execution or providing for any appraisement, valuation, stay of execution, exemption from civil process, redemption or extension of time for payment; all notices of any Event of Default or of the Mortgagee’s or any other Secured Person’s intention to accelerate the Secured Obligations or of any election to exercise or any actual exercise of any right, remedy or recourse provided for hereunder or under any Secured Document or available at law; and any

- 10 -

right to a marshalling of assets or a sale in inverse order of alienation. If any law referred to in this Deed of Trust and now in force, of which the Mortgagor or its successor or successors might take advantage despite the provisions hereof, shall hereafter be repealed or cease to be in force, such law shall thereafter be deemed not to constitute any part of the contract herein contained or to preclude the operation or application of the provisions hereof. If the laws of any state which provides for a redemption period do not permit the redemption period to be waived, the redemption period shall be specifically reduced to the minimum amount of time allowable by statute.

Section 4.13 Application of Proceeds. The proceeds of any foreclosure sale of the Collateral or any part thereof and all other monies received in any other proceedings for the enforcement hereof shall be applied:

(a) First, to the payment of all reasonable expenses incurred by the Trustee or the Mortgagee incident to the enforcement of this Deed of Trust, the Collateral Agency Agreement or any Secured Document to collect any portion of the Secured Obligations (including, without limiting the generality of the foregoing, expenses of any entry or taking of possession, of any sale, of advertisement thereof, and of conveyances, and court costs, compensation of agents and employees, legal fees and a reasonable commission to the Trustee acting, if applicable), and to the payment of all other reasonable charges, expenses, liabilities and advances incurred or made by the Trustee or the Mortgagee under this Deed of Trust or in executing any trust or power hereunder; and

THE TRUSTEE

Section 5.01 Duties, Rights, and Powers of Trustee. The Trustee shall have no duty to see to any recording, filing or registration of this Deed of Trust or any other instrument in addition or supplemental thereto, or to give any notice thereof, or to see to the payment of or be under any duty in respect of any tax or assessment or other governmental charge which may be levied or assessed on the Collateral, or any part thereof, or against the Mortgagor, or to see to the performance or observance by the Mortgagor of any of the covenants and agreements contained herein. The Trustee shall not be responsible for the execution, acknowledgment or validity of this Deed of Trust or of any instrument in addition or supplemental hereto or for the sufficiency of the security purported to be created hereby, and makes no representation in respect thereof or in respect of the rights of the Mortgagee. The Trustee shall have the right to consult with counsel upon any matters arising hereunder and shall be fully protected in relying as to legal matters on the advice of counsel. The Trustee shall not incur any personal liability hereunder except for the Trustee’s own gross negligence or willful misconduct; and the Trustee shall have the right to rely on any instrument, document or signature authorizing or supporting any action taken or proposed to be taken by him hereunder, believed by him in good faith to be genuine.

Section 5.02 Successor Trustee. The Trustee may resign by written notice addressed to the Mortgagee or be removed at any time with or without cause by an instrument in writing duly executed on behalf of the Mortgagee. In case of the death, resignation or removal of the Trustee, a successor may be appointed by the Mortgagee by instrument of substitution complying with any applicable Governmental Requirements, or, in the absence of any such requirement, without formality other than appointment and designation in writing. Written notice of such appointment and designation shall be given by the Mortgagee to the Mortgagor, but the validity of any such appointment shall not be impaired or affected by failure to give such notice or by any defect therein. Such appointment and designation shall be full evidence of the right and authority to make the same and of all the facts therein recited. Upon the making of any such appointment and designation, this Deed of Trust shall vest in the successor, and the successor shall thereupon succeed to, all of the rights, powers, privileges, immunities and duties hereby conferred upon the Trustee named herein, and one such appointment and designation shall not exhaust the right to appoint and designate an additional successor but such right may be exercised repeatedly until the Release Date. To facilitate the administration of the duties hereunder, the Mortgagee may appoint multiple trustees to serve in such capacity or in such jurisdictions as the Mortgagee may designate.

Section 5.03 Retention of Moneys. All moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated in any manner from any other moneys (except to the extent required by law) and the Trustee shall be under no liability for interest on any moneys received by him hereunder.
