Item 1.01      Entry into a Material Definitive Agreement

     On October 26, 2004, the Board of Directors of Encore Acquisition Company, a Delaware corporation (“Encore”), approved indemnity agreements between Encore and its officers and directors (each an “indemnitee”). The indemnity agreements provide for indemnification by Encore of each indemnitee to the fullest extent permitted by Delaware law for claims relating to the indemnitee’s service as an officer or director, excluding any claim in which a judgment determines that the indemnitee personally gained financial profit or other advantage to which he was not legally entitled and acted in bad faith or was deliberately dishonest in a manner that was material to the claim. The agreements also provide for advancement of expenses relating to the indemnification obligations and obligate Encore to purchase and maintain liability insurance for each indemnitee’s acts as an officer or director.
