On January 13, 2011, EXCO Resources, Inc. (“EXCO”) issued a press release reporting its year-end 2010 proved reserves. A copy of this press release is being furnished as Exhibit 99.1 to this report.

On January 12, 2011, EXCO and the Special Committee of the Board of Directors (“Special Committee”) entered into an agreement (the “Confidentiality Agreement”) with Douglas Miller containing customary confidentiality and standstill provisions. The standstill provisions prohibit Mr. Miller from, among other things, acquiring additional shares of EXCO common stock, entering into agreements regarding or soliciting proxies in connection with an acquisition of EXCO and seeking to influence the management of EXCO in connection with such an acquisition. In addition, the Confidentiality Agreement prohibits Mr. Miller from entering into agreements preventing EXCO shareholders from voting in favor of or tendering their shares in other offers to acquire EXCO or preventing financing sources from providing financing to other parties in connection with an acquisition of EXCO. The Confidentiality Agreement also limits the parties with whom Mr. Miller can enter into financing arrangements. The Special Committee expects to enter into similar agreements with other parties interested in exploring a possible acquisition of EXCO. The foregoing description of the Confidentiality Agreement is not complete and is qualified in its entirety by reference to the full text of the Confidentiality Agreement, a copy of which is filed herewith as Exhibit 99.2 and is incorporated by reference herein.
