ASSIGNMENT
     THIS ASSIGNMENT (this “Assignment”) is executed and delivered by CMR ENERGY, L.P., a Texas limited partnership, and ARROW RIVER ENERGY, L.P., a Texas limited partnership (being collectively referred to as “CMR”), to THE EXPLORATION COMPANY OF DELAWARE, INC., a Delaware corporation (“TXCO”).
     WHEREAS, this Assignment is made and delivered pursuant to (i) that certain Purchase and Sale Agreement dated September 26, 2005 (the “Agreement”), by and between TXCO, as “Seller,” and ENCANA OIL & GAS (USA) INC., a Delaware corporation (“EnCana”), as “Buyer,” and (ii) that certain Purchase and Sale Agreement dated September 26, 2005, by and between CMR, as “Seller,” and EnCana, as “Buyer”; and
     WHEREAS, CMR desires to convey to TXCO, certain of CMR’s oil and gas rights in and to the Glen Rose Formation (as defined herein) save and except the Excluded Interests (hereinafter defined), and TXCO desires to accept such conveyance.
     NOW THEREFORE, subject to the terms and conditions of this Assignment, CMR, for valuable consideration, the receipt and sufficiency of which are hereby acknowledged, does by these presents ASSIGN, TRANSFER, SELL, CONVEY, SET OVER and DELIVER unto TXCO, all of CMR’s right, title and interest in and to the following, to the extent, and only to the extent, NOT included within the Excluded Assets (hereinafter defined) (collectively, the “Assets”):
All of the oil and gas leasehold interests described on Exhibit A attached hereto (the “Leases”), to the extent, and only to the extent, that said interests cover rights and production in and to the Glen Rose Formation. For purposes hereof, the “Glen Rose Formation” shall mean the stratigraphic equivalent of that certain interval located between 6130' and 8171' as shown on the electric log of the Union Producing Company - E. Halsell #1 (API 42 323 01126) located in Maverick County, Texas.
     CMR does hereby SAVE AND EXCEPT from this Assignment and RESERVE unto itself, its successors and assigns, the following wells, units, properties, interests and other assets (collectively, the “Excluded Assets”):
  (1)   the wells described on Exhibit B attached hereto (collectively, the “Excluded Wells”), and the Leases insofar, and only insofar, as the Leases are included within the units for such wells described on Exhibit G attached hereto (collectively, the “Excluded Units”); and

1

  (2)   an undivided twenty-two and one-half percent (22 1/2%) of eight-eighths (8/8ths) interest in and to the oil and gas leases described on Exhibit C attached hereto.
     TO HAVE AND TO HOLD all and singular the Assets, together with all rights, titles, interests, estates, remedies, powers and privileges thereunto appertaining unto TXCO and its successors and assigns forever, subject to the terms and conditions set forth herein. CMR hereby binds itself and its successors to warrant and forever defend, subject to the terms and conditions set forth herein, the Assets unto TXCO, its successors and assigns, against every person whomsoever lawfully claiming or to claim the same or any part thereof, by, through or under CMR, but not otherwise.
     Permitted Encumbrances. This Assignment is subject to all covenants, agreements, easements, rights-of-way, servitudes, encumbrances and other matters of record in the real property records of the counties in which the Assets are located, to the extent the same are valid and subsisting and affect all or any part of the Assets; provided, however, the Assets are being assigned by CMR to TXCO hereunder free and clear of all liens, mortgages, deeds of trusts, security interests, fixture filings and financing statements.
     Further Assurances. CMR and TXCO will execute and deliver to each other all other additional instruments, notices, assumptions, and other documents, and will do and take all such other acts and things, as TXCO reasonably may deem necessary, appropriate, or desirable (i) to more fully protect the rights of TXCO and its successors and assigns under this Assignment, (ii) to more fully transfer, assign, and deliver to TXCO and its successors and assigns the Assets or (iii) for the purpose of giving effect to, evidencing or giving notice of the transactions evidenced by this Assignment.
     Savings Clause. If there are prohibitions against or conditions to the conveyance of one or more portions of the Assets without the prior written consent of third parties that, if not satisfied, would result in a breach thereof by CMR or would give an outside party the right to terminate CMR’s or TXCO’s rights with respect to such Assets (any such prohibition or condition being herein called a “Restriction”), then notwithstanding anything herein to the contrary, the transfer of title to, or interest in, such portion of the Assets through this Assignment shall not become effective unless and until such Restrictions are satisfied or waived by the parties hereto, or becomes otherwise inoperable or unenforceable. To the extent complete legal and equitable title to such Assets is prohibited from being conveyed from CMR to TXCO until such Restrictions are obtained, CMR shall continue to hold bare legal title to such Assets as nominee for TXCO. As nominee, CMR shall not be authorized to take and shall not take any action with respect to such Assets except to the extent expressly authorized and directed in writing by TXCO. Further, CMR shall exercise all voting rights with respect to such Assets as directed by TXCO in writing. For purposes hereof, CMR and TXCO shall treat and deal with such Assets as if full legal and equitable title to such Assets had passed from CMR to TXCO at the Effective Time. When and if such Restriction is so satisfied, waived or removed, the assignment of such portion of the Assets as may be subject thereto shall become effective automatically as of the date of this Assignment, without further action on the part of CMR or TXCO, respectively. Notwithstanding the foregoing, in the event any restrictions on the transfer

2

of any of the Assets which are not waived, released, satisfied or expired as of the date hereof are waived, released, satisfied or expired after the date hereof, CMR covenants to promptly execute and deliver an assignment of such Assets in form and substance substantially similar to this Assignment as reasonably requested by TXCO.
     Disclaimer of Warranties. THIS ASSIGNMENT IS BEING MADE ON AN “AS IS, WHERE IS AND WITH ALL FAULTS” BASIS, AND TXCO ACKNOWLEDGES THAT CMR HAS NOT MADE, AND, EXCEPT FOR THE TITLE WARRANTIES CONTAINED HEREIN, IS NOT MAKING, ANY REPRESENTATIONS OR WARRANTIES OF ANY KIND, NATURE OR DESCRIPTION, EXPRESSED OR IMPLIED, WITH RESPECT TO THE ASSETS, INCLUDING, WITHOUT LIMITATION, THE CONDITION OR WORKMANSHIP OF THE ASSETS OR THEIR MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE, AND CMR EXPRESSLY DISCLAIMS AND TXCO EXPRESSLY WAIVES ANY AND ALL SUCH WARRANTIES. TXCO ACKNOWLEDGES THAT IT HAS PERFORMED ITS OWN INSPECTIONS OF THE ASSETS AND IT IS RELYING ON SUCH INSPECTIONS AND NOT RELYING UPON ANY ORAL REPRESENTATIONS, WARRANTIES, PROMISES OR AGREEMENTS BY CMR OR ANY OFFICER, MANAGER, REPRESENTATIVE, ATTORNEY, OR AGENT OF CMR. TXCO AND CMR EACH HAVE BEEN REPRESENTED BY ITS OWN RESPECTIVE LEGAL COUNSEL IN THE PREPARATION OF THIS ASSIGNMENT AND THE NEGOTIATION OF ITS TERMS.
     Production; Taxes; Costs. All Hydrocarbons produced prior to the Effective Time (irrespective of whether payment for the same has been made or received) which are attributable to the Assets shall belong to CMR, and all such Hydrocarbons produced from and after the Effective Time shall belong to TXCO. All ad valorem, property, production, severance and similar taxes and assessments relative to the Assets shall be apportioned and prorated between TXCO and CMR as of the Effective Time, so that CMR shall bear such taxes and assessments prior to the Effective Time and TXCO shall be charged for all such taxes and assessments after the Effective Time. All costs and expenses with respect to the Assets which relate to the period prior to the Effective Time shall be the obligation of and be paid by CMR, and all costs and expenses with respect to the Assets which relate to the period after the Effective Time shall be the obligation of and be paid by TXCO. In connection with the execution and delivery of this Assignment, TXCO and CMR have executed a preliminary settlement statement allocating revenues, expenses, and taxes attributable to the Assets between TXCO and CMR, which allocation was based on the best information then available to them. On or before December 31, 2005, TXCO and CMR will make any adjustments and payments to each other as are necessary to reflect any new information that becomes available after preparation of the preliminary settlement statement. In connection with the foregoing settlement statement, each party shall have the right, upon reasonable notice and during normal business hours, to audit the books and records of the other party to determine compliance with this paragraph.
     Successors and Assigns. This Assignment shall be binding upon and inure to the benefit of the respective successors and permitted assigns of each of CMR and TXCO.
     Substitution and Subrogation. This Assignment is made with full substitution and subrogation of TXCO in and to all covenants and warranties by others not affiliated with CMR

3

heretofore given or made in respect of the Assets or any part thereof to or for the benefit of CMR.
     Counterparts. This Assignment may be executed in any number of counterparts and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same Assignment.
     IN WITNESS WHEREOF, the parties hereto have caused this Assignment to be duly executed effective, for all purposes, at 7:00 a.m. (in the locale where the Assets are located) on September 1, 2005 (the “Effective Time”).
