Item 6.

Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

The 11,000,000 shares of Common Stock held by Mr. Pickens are subject to a registration rights agreement, the terms of which are summarized below:

Overview. All of the shares of Common Stock that were issued in exchange for shares of EXCO Holdings Inc. when EXCO Holdings Inc. was merged with and into the Issuer on February 14, 2006 (50,000,000 shares total) are subject to the First Amended and Restated Registration Rights Agreement (the “Registration Rights Agreement”). On June 22, 2007, BP EXCO Holdings II LP transferred all of its 12,804,833 shares of Common Stock to Mr. Pickens. In connection with such transfer, Mr. Pickens became a party to the Registration Rights Agreement by entering into that certain Joinder Agreement to the Registration Rights Agreement dated June 22, 2007. The Registration Rights Agreement entitles the stockholders that are parties thereto to certain rights with respect to the registration of shares of Common Stock for resale under the Securities Act.

Registrations. Pursuant to the Registration Rights Agreement, after the IPO, all holders of unregistered shares of Common Stock who are subject to the Registration Rights Agreement can require the Issuer to register their shares in certain circumstances. In addition, at any time that the Issuer files a registration statement registering other shares, the holders of shares subject to the Registration Rights Agreement can require that the Issuer include their shares in such registration statement, subject to certain exceptions.

At any time on or after 180 days after the completion of the IPO, any holder of unregistered shares of the Common Stock who is party to the Registration Rights Agreement may request that the Issuer register up to one-third of the holder’s registrable securities in a resale registration statement. At any time on or after 365 days after the completion of the IPO, any holder of registrable securities may again require the Issuer to register up to an additional one-third of the holder’s registrable securities initially covered by the Registration Rights Agreement in the same manner as the initial resale registration was made. A similar demand right will be invocable by any holder with respect to its remaining registrable securities commencing 540 days after completion of the IPO. Upon any such request for registration, the Issuer would then be required to give notice of the requested registration to all other holders of registrable securities to allow such other holders to register up to one-third of their registrable securities on the same registration statement. Following the IPO, the Issuer may request in writing that J.P. Morgan Securities Inc. waive the registration waiting periods and registration volume limitations on resale registrations described in this paragraph. Upon or without such a request, J.P. Morgan Securities Inc., in its sole discretion and based upon its evaluation of market conditions, the historical trading activity and liquidity of the Common Stock and other considerations it deems relevant, may waive continued application of the registration waiting periods and registration volume limitations described in this paragraph. The Issuer requested that J.P. Morgan Securities Inc. waive the waiting period for the last one-third tranche of restricted shares with the effect of permitting us to register both the second and third tranche of restricted shares after February 14, 2007. On January 11, 2007, J.P. Morgan Securities Inc. granted this waiver. The Issuer’s Registration Statement on Form S-3 (No. 333-142361) filed with the Securities and Exchange Commission on April 25, 2007 covers the resale of all restricted shares subject to the Registration Rights Agreement.

If the Issuer at any time or from time to time proposes to register any of its securities under the Securities Act, other than in an initial public offering or registrations on Form S-4 or Form S-8, then all holders, or all former holders, of registrable securities, if such shares have not been previously registered, will be entitled to piggyback registration rights, allowing them to have their shares included in the registration. These piggyback registrations are subject to delay or termination of the registration in certain circumstances.

Postponements and limitations. Under certain circumstances, the Issuer may postpone a registration if its board of directors determines in good faith that effecting such a registration or continuing the disposition of Common Stock would have a material adverse effect on the Issuer, or would not be in the Issuer’s best interests. Furthermore, the underwriters of the registration may, subject to certain limitations, limit the number of shares included in the registration.

Founders common stock. The Registration Rights Agreement provides, until the third anniversary of the Registration Rights Agreement, that certain holders of the Common Stock, who originally purchased shares of common stock of EXCO Holdings II, Inc. (which was merged with and into EXCO Holdings Inc. on October 3, 2005) issued prior to October 3, 2005, or the “founders,” may only sell their Common Stock pursuant to an effective registration statement covering the resale of such founder’s shares and may not sell their shares pursuant to Rule 144 or any other exemption from registration or otherwise.

Amendments and waivers. The provisions of the Registration Rights Agreement may not be amended, terminated or waived without the written consent of the Issuer, holders of a majority of the shares then held by the outside investors and holders of a majority of the shares then held by the management investors.

Holdback arrangements. Upon entering into the Registration Rights Agreement, each holder of registrable securities agreed that, at the request of the sole or lead managing underwriter in an underwritten offering, it would not make any short sale of, loan, grant any option for the purchase of or effect any public sale or distribution, including a sale pursuant to Rule 144 under the Securities Act, of any registrable securities during the five days prior to, and the time period (up to 90 days) requested by the underwriter following an underwritten offering. The holders of registrable securities will be subject to these restrictions for 180 days following the effective date of the registration statement filed with respect to the IPO.

As part of the compensation arrangements for the board of directors of EXCO Holdings Inc., on October 5, 2005, Mr. Pickens was granted an option to acquire 50,000 shares of common stock of EXCO Holdings Inc. at an exercise price of $7.50 per share pursuant to a Nonqualified Stock Option Agreement. The option expires on October 5, 2015. The option vests in four equal annual installments, beginning on October 5, 2005. In connection with the merger of EXCO Holdings Inc. with and into the Issuer, the Issuer assumed the Nonqualified Stock Option Agreement, and the option to purchase shares of common stock of EXCO Holdings Inc. became an option to purchase an equal number of shares of common stock of the Issuer. All other terms of the Nonqualified Stock Option Agreement remain the same.

Except for the Registration Rights Agreement, the Joinder to the Registration Rights Agreement, the Nonqualified Stock Option Agreement and the Joint Filing Agreement attached hereto, there are no contracts, arrangements, understandings or relationships between the Filing Person and any other person with respect to the securities of the Issuer.
