Interest Payment under the Amended and Restated Credit Agreement

On August 31, 2011, Cano Petroleum, Inc., a Delaware corporation (“Cano”), failed to make the required payment of interest in the amount of $130,579.51 under its Amended and Restated Credit Agreement (“ARCA”).  The failure to make such payment of interest constitutes an Event of Default under the ARCA and Cano’s Subordinated Credit Agreement (the “SCA”), for which the lenders under the ARCA and the SCA may terminate their obligation to extend credit to Cano and declare all amounts payable under the ARCA and the SCA due and payable in full.  Cano has not received any notice from the lenders with respect to the exercise of their respective rights, including any right to accelerate the amounts payable by Cano.

Redemption of Series D Convertible Preferred Stock

As a result of the defaults described above and the other defaults previously described in Cano’s filings with the Securities and Exchange Commission, Cano will not redeem its Series D Convertible Preferred Stock, no par value per share (“Preferred Stock”), on September 6, 2011 as provided for in the Certificate of Designations, Preferences and Rights of Preferred Stock (the “Certificate of Designations”).  The subordination provisions contained in the Certificate of Designations prohibit Cano from redeeming Preferred Stock while Cano is in default under the ARCA.
