Item 1.01               Entry into a Material Definitive Agreement.

On September 29, 2009, Cano Petroleum, Inc. (the “Company” or “Cano”) and Resaca Exploitation, Inc., a Texas corporation (“Resaca”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among the Company, Resaca and Resaca Acquisition Sub, Inc., a Delaware corporation and wholly-owned subsidiary of Resaca (“Merger Sub”), pursuant to which Merger Sub will be merged with and into the Company (the “Merger”) and the Company will become a wholly-owned subsidiary of Resaca.  The Merger Agreement was attached as Exhibit 2.1 to the Company’s current report on Form 8-K filed with the Securities Exchange Commission on October 1, 2009.

The Company entered into Stock Voting Agreements with the following holders (collectively, the “Preferred Holders”) of Cano’s Series D Convertible Preferred Stock (the “Preferred Stock”) on the dates as follows: Trapeze Capital Corp. on Behalf of Managed Accounts on October 15, 2009, Trapeze Asset Management Inc. on Behalf of Managed Accounts on October 15, 2009, Kellogg Capital Markets LLC on October 15, 2009, Investcorp Interlachen Multi-Strategy Master Fund Limited on October 16, 2009, and O’Connor Pipes Corporate Strategies Master Limited on October 20, 2009.  As previously reported, the Company also entered into a Stock Voting Agreement with D. E. Shaw Laminar Portfolios, L.L.C. (“D. E. Shaw”) on September 29, 2009.  In the aggregate, the Preferred Holders and D. E. Shaw own approximately 75% of the Preferred Stock.  Each Stock Voting Agreement contains the same terms and provides, among other things, that each of the Preferred Holders will vote all its shares of Company stock (a) in favor of an amendment to the Certificate of Designations, Preferences and Rights of Series D Convertible Preferred Stock of the Company (the “Series D Amendment”), (b) in favor of adoption of the Merger Agreement, and (c) in accordance with the recommendation of the Board of Directors of the Company in connection with any Target Acquisition Proposal (as such term is defined in the Merger Agreement).  The Series D Amendment generally provides that the holders of Preferred Stock shall have no rights arising from the proposed Merger with Resaca (including any right to require the Company to redeem their shares of Preferred Stock) other than the right to receive the merger consideration specified in the Merger Agreement.  To be effective, the Series D Amendment must be approved by the holders of a majority of the shares of Preferred Stock, voting as a separate class, and by the holders of a majority of the shares of the Company’s common stock, voting as a separate class, and then filed by the Company with the Secretary of State of Delaware.

On October 20, 2009, the Company entered into a Stock Voting Agreement with S. Jeffrey Johnson, Cano’s Chief Executive Officer and a member of the Company’s board of directors, which provides, among other things, that Mr. Johnson will vote all of his shares of Company stock in favor of the Series D Amendment.   Mr. Johnson owns approximately 3.7% of the Preferred Stock. The Preferred Holders, D. E. Shaw and Mr. Johnson collectively own approximately 78.7% of the Preferred Stock.

Each of the Preferred Holders and Mr. Johnson also agreed to deliver an irrevocable proxy to the Company and not to transfer any of their shares of Company stock during the terms of their respective Stock Voting Agreements.  The Stock Voting Agreements will terminate on the earlier of (a) the effective time of the Merger, (b) the termination of the Merger Agreement in accordance with its terms, (c) any amendment, modification or supplement to the Merger Agreement or any waiver by any party thereto that is adverse to the interests of the applicable Preferred Holder or Mr. Johnson without the prior written consent of such Preferred Holder or Mr. Johnson, as applicable, and (d) the failure of Resaca to assume certain of the Company’s obligations with respect to the Preferred Stock.

The form of Stock Voting Agreement entered into by the Preferred Holders is filed herewith as Exhibit 10.1 and is incorporated herein by reference. The form of Stock Voting Agreement entered into by Mr. Johnson is filed herewith as Exhibit 10.2 and is incorporated herein by reference. The foregoing description of the Stock Voting Agreements and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the forms of Stock Voting Agreement.
