Item 1.01  Entry into a Material Definitive Agreement.

On December 31, 2009, TXCO Resources Inc. (the “Company”) and its subsidiaries TXCO Energy Corp., Texas Tar Sands Inc., Output Acquisition Corp., Opex Energy, LLC, Charro Energy, Inc., TXCO Drilling Corp., Eagle Pass Well Service, L.L.C., PPL Operating, Inc., Maverick Gas Marketing, Ltd., and Maverick-Dimmit Pipeline, Ltd. (collectively, “TXCO”), entered into a definitive Purchase and Sale Agreement (the “Agreement”) to sell a substantial portion of TXCO’s assets to Anadarko E&P Company LP for total consideration of the lesser of (i) $1 million more than the sum of the amounts sufficient to (a) repay TXCO’s lenders (including TXCO’s debtor-in-possession financing and revolver or term loan credit facilities), (b) pay all other creditors of TXCO in full, including interest thereon, and (c) pay any cure amounts of executory contracts to be assumed by Anadarko (other than Anadarko’s claims which will be waived at closing), or (ii) $310 million in cash, subject to customary purchase price adjustments.  The sale is expected to close before February 28, 2010, but the economic effective date of the sale will be January 1, 2010.

Under the terms of the Agreement, certain assets are excluded from the assets being purchased by Anadarko and will be retained by TXCO, including, among others, TXCO’s drilling rigs, offshore properties, Oklahoma properties, non-operated properties within the Williston Basin, non-operated properties in south Texas outside of Maverick, LaSalle, Zavala and Dimmit Counties, and its interests in the “Dexter Waterflood Unit”, the “Forrest WM B1U” and the “Vinton Dome.”

TXCO previously entered into a definitive Purchase and Sale Agreement (the “Newfield PSA”) on November 6, 2009, to sell the same assets covered by the Agreement to Newfield Exploration Company for total consideration of $223 million.  The board of directors of TXCO has determined that the Agreement constitutes a superior proposal to the Newfield PSA.  Accordingly, TXCO intends to seek the entry of an order of the Bankruptcy Court authorizing the transactions contemplated by the Agreement.  If the Bankruptcy Court authorizes the transactions contemplated by the Agreement, the Newfield PSA will be terminated.

TXCO filed voluntary petitions for relief under Chapter 11 of the U.S. Bankruptcy Code with the United States Bankruptcy Court for the Western District of Texas (the “Bankruptcy Court”) on May 17, 2009.  TXCO continues to operate its business as debtor-in-possession under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court.  As debtors-in-possession, TXCO may not engage in transactions outside the ordinary course of business without the prior approval of the Bankruptcy Court.  Accordingly, the consummation of the sale of assets to Anadarko contemplated by the Agreement is subject to the entry of a final order of the Bankruptcy Court authorizing the sale.  TXCO’s currently proposed Plan of Reorganization contemplated the potential submission of superior proposals to that contained in the Newfield PSA and TXCO intends to file a proposed amended plan of reorganization, to the extent necessary, incorporating the terms of the Agreement with the Bankruptcy Court.The Company currently does not expect that holders of the Company’s equity securities will receive any cash or other property in respect of such securities, and it is likely that such securities will be cancelled under the plan of reorganization.  Accordingly, the Company urges that extreme caution be exercised with respect to existing and future investments in any Company equity securities.

2

The Agreement contains customary representations, warranties, covenants, and indemnities of TXCO and Anadarko.  In addition to having to obtain the Bankruptcy Court’s approval, the completion of the sale of assets to Anadarko is subject to various customary conditions, including, among others, (i) subject to certain materiality qualifications, the accuracy of the representations and warranties made by Anadarko and TXCO, respectively, and compliance by Anadarko and TXCO with their respective obligations under the Agreement, (ii) the absence of any pending lawsuit, action, or other proceeding seeking to restrain or prohibit the consummation of the sale transaction, and (iii) the aggregate sum of all casualty and condemnation losses not exceeding 10% of the unadjusted purchase price.

TXCO has agreed not to solicit proposals relating to alternative acquisition transactions, provided, however, that TXCO may still (i) respond to inquiries and provide access to information to persons that TXCO determines may submit a superior proposal, and (ii) engage in negotiations or discussions with any person who makes an unsolicited acquisition proposal that is, or is reasonably likely to be, a superior proposal if TXCO determines that such negotiations or discussions are necessary in order to comply with applicable law.  The deadline for any person to submit an alternative acquisition proposal is 5:00 p.m. central time on January 6, 2010.  TXCO is required to provide Anadarko with notice by no later than January 13, 2010, if TXCO intends to pursue a superior proposal or alternative plan of reorganization.  Additionally, if TXCO elects to pursue a superior proposal or alternative plan of reorganization that is not ultimately consummated, TXCO has agreed to offer Anadarko a back-up bid option following the failure of the superior proposal or alternative plan of reorganization giving Anadarko the right to consummate the purchase of assets on substantially the same terms and conditions contemplated by the Agreement.  However, the back-up bid option offered to Anadarko is subordinate to the existing back-up bid option offered to Newfield under the terms of the Newfield PSA.

The Agreement also contains certain termination rights for each of Anadarko and TXCO, including, among others, the right of either party to terminate the Agreement if TXCO enters into or seeks Bankruptcy Court approval of a superior proposal or alternative plan of reorganization, and Anadarko’s right to terminate (i) if the Bankruptcy Court has not entered an order on or before January 31, 2010 authorizing the sale of the assets to Anadarko, and (ii) if an order of the Bankruptcy Court authorizing the sale of the assets to Anadarko is not final by February 15, 2010.  In addition, the Agreement will be deemed terminated upon the consummation of any superior proposal or alternative plan of reorganization.

The foregoing description of the Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Agreement, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.

The Agreement has been included to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual or financial information about TXCO or its subsidiaries and affiliates. The representations, warranties, and covenants contained in the Agreement were made only for purposes of that agreement and as of specific dates; were solely for the benefit of the parties to the Agreement; may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Agreement instead of establishing these matters as facts; and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors should not rely on the representations, warranties and covenants or any description thereof as characterizations of the actual state of facts or condition of TXCO or any of its subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations, warranties, and covenants may change after the date of the Agreement, which subsequent information may or may not be fully reflected in public disclosures by TXCO. The Agreement should not be read alone, but should instead be read in conjunction with the other information regarding TXCO that will be contained in, or incorporated by reference into, other filings that TXCO makes with the SEC.

3

Most of TXCO’s filings with the Bankruptcy Court are available to the public at the offices of the Clerk of the Bankruptcy Court or the Bankruptcy Court’s web site (http://www.txwb.uscourts.gov/) or may be obtained through private document retrieval services, or on the web site established by TXCO’s claims and noticing agent (http://cases.administarllc.com/txco). Information contained on, or that can be accessed through, such web sites or the Bankruptcy Court's web site is not part of this report.

Forward-Looking Statements

This Current Report on Form 8-K may contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended.  Statements by TXCO (which term, unless otherwise specified or the context otherwise requires, refers to TXCO Resources Inc. and its subsidiaries) of expectations, anticipations, beliefs, plans, intentions, targets, estimates, or projections and similar expressions relating to the future are forward-looking statements within the meaning of these laws.  Forward-looking statements in some cases can be identified by their being preceded by, followed by or containing words such as “estimate,” “plan,” “project,” “forecast,” “intend,” “expect,” “anticipate,” “believe,” “seek,” “target” and other similar expressions.  Forward-looking statements are based on assumptions and assessments made by TXCO’s management in light of their experience and their perception of historical trends, current conditions, expected future developments and other factors they believe to be appropriate.  Any forward-looking statements are not guarantees of TXCO’s future performance and are subject to risks and uncertainties that could cause actual results, developments and business decisions to differ materially from those contemplated by any forward-looking statements.  Except as required by law, TXCO undertakes no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise.

Some of the factors that may cause actual results, developments and business decisions to differ materially from those contemplated by any forward-looking statements include the following: the ability of TXCO to continue as a going concern; TXCO’s ability to satisfy the conditions for drawing on any existing debtor-in-possession financing and to obtain additional debtor-in-possession financing on an interim or final basis; the ability of TXCO to operate pursuant to the terms and conditions of any debtor-in-possession financing and any cash collateral order entered by the Bankruptcy Court in connection with TXCO’s bankruptcy cases; TXCO’s ability to obtain court approval with respect to motions in the chapter 11 cases prosecuted by TXCO from time to time; TXCO’s ability to develop, prosecute, confirm and consummate a plan of reorganization with respect to TXCO’s bankruptcy cases; risks associated with third parties seeking and obtaining court approval to terminate or shorten the exclusivity period that TXCO has to propose and confirm a plan of reorganization, for the appointment of a chapter 11 trustee or to convert TXCO’s bankruptcy cases to cases under chapter 7 of the U.S. Bankruptcy Code; TXCO’s ability to obtain and maintain normal terms with vendors and service providers; TXCO’s ability to maintain contracts that are critical to its operations; the potential adverse impact of TXCO’s bankruptcy cases on TXCO’s liquidity or results of operations; TXCO’s ability to fund and execute its business plan; TXCO’s ability to attract, motivate and retain key executives and employees; TXCO’s ability to attract and retain vendors and service providers, TXCO’s ability to obtain capital to fund TXCO’s working capital needs; the adequacy of TXCO’s liquidity and its ability to meet its cash commitments, working capital needs, lender and vendor obligations; general market conditions; adverse capital and credit market conditions; the costs and accidental risks inherent in exploring and developing new oil and natural gas reserves; the price for which such reserves and production can be sold; fluctuation in prices of oil and natural gas; the uncertainties inherent in estimating quantities of proved reserves and cash flows; competition; actions by third party co-owners in properties in which TXCO also owns an interest; acquisitions of properties and businesses; operating hazards; environmental concerns affecting the drilling of oil and natural gas wells; impairment of oil and natural gas properties due to depletion or other causes; and hedging decisions, including whether or not to hedge; TXCO’s ability to secure additional financing; and other risks referenced from time to time in TXCO’s filings with the Securities and Exchange Commission, including the risk factors listed in Part II, Item 1A, “Risk Factors” in TXCO’s Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2009, filed with the Securities and Exchange Commission on November 9, 2009. Similarly, these and other factors, including the terms of any reorganization plan ultimately confirmed, can affect the value of TXCO’s various pre-petition liabilities and TXCO Resources Inc.’s common stock and preferred stock.  No assurance can be given as to what values, if any, will be ascribed in the chapter 11 cases to each of these constituencies. Based on current discussions with TXCO’s debtor-in-possession lenders and other potential sponsors of a plan of reorganization, the Company currently does not expect that holders of the Company’s equity securities will receive any cash or other property in respect of such securities, and it is likely that such securities will be cancelled under the plan of reorganization.  Accordingly, TXCO urges that extreme caution be exercised with respect to existing and future investments in any of these pre-petition liabilities or equity securities.

Each adjustment to the Purchase Price described in Sections 2.3(a) through (f) shall be applied to the portion of the Purchase Price payable to the Sellers which owns the affected Asset.

Section 2.4            Allocation of Purchase Price.  Except as provided in Section 3.1(a), twenty (20) days prior to the Closing, Purchaser shall prepare and deliver to Sellers an allocation of the unadjusted Purchase Price among each of the Assets (the “Allocated Values”).  Any adjustments to the Purchase Price pursuant to Sections 2.3(a) through (f) shall be applied to the Allocated Values for the particular affected Assets.  Sellers and Purchaser will accept such Allocated Values for purposes of this Agreement only and the transactions contemplated hereby, but will otherwise make no representation or warranty as to the accuracy of such values.  Sellers and Purchaser agree that (i) the purchase and sale described herein is not a transaction subject to the provisions of section 1060 of the Internal Revenue Code of 1986, as amended (the “Code”), and (ii) the Allocated Values agreed for purposes of this Section 2.4 are not necessarily those that would be determined in accordance with the principles of section 1060 of the Code and the Treasury Regulations thereunder.

(a)         For purposes of this Article 10, the term “Indemnifying Person” when used in connection with particular Damages shall mean the Person or Persons having an obligation to indemnify another Person or Persons with respect to such Damages pursuant to this Article 10, and the term “Indemnified Person” when used in connection with particular Damages shall mean the Person or Persons having the right to be indemnified with respect to such Damages by another Person or Persons pursuant to this Article 10.

(b)         To make claim for indemnification under Section 10.1, an Indemnified Person shall notify the Indemnifying Person of its claim under this Section 10.2, including the specific details of and specific basis under this Agreement for its claim (the “Claim Notice”).  In the event that the claim for indemnification is based upon a claim by a third party against the Indemnified Person (a “Claim”), the Indemnified Person shall provide its Claim Notice promptly after the Indemnified Person has actual knowledge of the Claim and shall enclose a copy of all papers (if any) served with respect to the Claim; provided that the failure of any Indemnified Person to give notice of a Claim as provided in this Section 10.2 shall not relieve the Indemnifying Person of its obligations under Section 10.1 except to the extent such failure results in insufficient time being available to permit the Indemnifying Person to effectively defend against the Claim or otherwise prejudices the Indemnifying Person's ability to defend against the Claim.  In the event that the claim for indemnification is based upon an inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement which was inaccurate or breached.

(c)         If the Indemnifying Person admits its obligation to indemnify the Indemnified Person, it shall have the right and obligation to diligently defend, at its sole cost and expense, the Claim.  The Indemnifying Person shall have full control of such defense and proceedings, including any compromise or settlement thereof.  If requested by the Indemnifying Person, the Indemnified Person agrees to cooperate in contesting any Claim which the Indemnifying Person elects to contest (provided, however, that the Indemnified Person shall not be required to bring any counterclaim or cross-complaint against any Person).  The Indemnified Person may at its own expense participate in, but not control, any defense or settlement of any Claim controlled by the Indemnifying Person pursuant to this Section 10.2(d).  An Indemnifying Person shall not, without the written consent of the Indemnified Person, settle any Claim or consent to the entry of any judgment with respect thereto which (i) does not result in a final resolution of the Indemnified Person's liability with respect to the Claim (including, in the case of a settlement, an unconditional written release of the Indemnified Person) or (ii) may materially and adversely affect the Indemnified Person (other than as a result of money damages covered by the indemnity).

-33-

(d)        If the Indemnifying Person does not admit its obligation or admits its obligation but fails to diligently defend or settle the Claim, then the Indemnified Person shall have the right to defend against the Claim (at the sole cost and expense of the Indemnifying Person, if the Indemnified Person is entitled to indemnification hereunder), with counsel of the Indemnified Person's choosing, subject to the right of the Indemnifying Person to admit its obligation and assume the defense of the Claim at any time prior to settlement or final determination thereof.  If the Indemnifying Person has not yet admitted its obligation to provide indemnification with respect to a Claim, the Indemnified Person shall send written notice to the Indemnifying Person of any proposed settlement and the Indemnifying Person shall have the option for 10 days following receipt of such notice to (i) admit in writing its obligation to provide indemnification with respect to the Claim and (ii) if its obligation is so admitted, reject, in its reasonable judgment, the proposed settlement.  If the Indemnified Person settles any Claim over the objection of the Indemnifying Person after the Indemnifying Person has timely admitted its obligation in writing and assumed the defense of the Claim, the Indemnified Person shall be deemed to have waived any right to indemnity therefor.

Section 10.3          Limitation on Actions.  Notwithstanding the remaining provisions hereof, the provisions of this Article 10 are subject to the following:

(a)         The representations and warranties of the Parties set forth in this Agreement or any certificate or other instrument delivered pursuant hereto, as well as the covenants and agreements set forth herein or therein that are contemplated to be performed prior to the Closing, shall survive the Closing for a period of one hundred eighty (180) days after the Closing (unless a shorter period is expressly provided within the applicable section).  The covenants and agreements set forth herein or therein that are contemplated to be performed after the Closing, shall survive the Closing without time limit except as may otherwise be expressly provided herein or therein.  Representations, warranties, covenants and agreements shall be of no further force and effect after the date of their expiration, provided that there shall be no termination of any bona fide claim asserted pursuant to this Agreement with respect to such a representation, warranty, covenant or agreement prior to its expiration date.

(b)         The indemnities in Sections 10.1(a)(ii), 10.1(a)(iii) and 10.1(b) shall terminate as of the date that is one hundred eighty (180) days after the Closing, except in each case as to matters for which a specific written claim for indemnity has been delivered to the Indemnifying Person on or before such termination date.  The indemnities in Section 10.1(a)(i) shall continue without time limit.

(d)         The maximum aggregate amount for which Sellers may be liable for indemnification under Section 10.1 shall be limited to Two Million Dollars ($2,000,000).

(e)         The amount of any Damages for which an Indemnified Person is entitled to indemnity under this Article 10 shall be reduced by the amount of insurance proceeds realized by the Indemnified Person or its Affiliates with respect to such Damages (net of any collection costs, and excluding the proceeds of any insurance policy issued or underwritten by the Indemnified Person or its Affiliates).

(f)         In no event shall the Purchaser have any obligation hereunder to indemnify any Seller who does not actually convey any portion of the Assets to Purchaser under this Agreement or otherwise have any direct or indirect interest in any portion of the Assets.  Likewise, no Seller who does not actually convey any portion of the Assets to Purchaser under this Agreement or otherwise have any direct or indirect interest in any portion of the Assets shall have any obligation hereunder to indemnify the Purchaser.  Upon the request of any Party hereto, the Parties agree to enter into any amendment to this Agreement reasonably necessary to remove any Seller who does not actually convey any portion of the Assets to Purchaser under this Agreement or otherwise have any direct or indirect interest in any portion of the Assets as a Party to this Agreement.
