AGREEMENT

This Agreement dated as of October 14, 2002, is by and between EXCO Resources, Inc., a Texas corporation (the "Company") and Xxxxxxx X. Xxxxxx ("Xx. Xxxxxx"), along with any person or entity who executes a joinder agreement as provided below (each, a "Joinder Party").

1. Introduction. On August 6, 2002, Xx. Xxxxxx, the Chairman of the Board and Chief Executive Officer of the Company, submitted to the Board of Directors of the Company a preliminary proposal to acquire all of the outstanding shares of capital stock of the Company, subject to certain conditions (the "Initial Proposal"). In light of Xx. Xxxxxx'x position as an executive officer and director of the Company, a special committee of the Board of Directors was formed on August 15, 2002 (the "Special Committee") to exercise the powers of the Board of Directors with respect to the Initial Proposal and any alternative proposals.

Xx. Xxxxxx has advised the Special Committee that, in connection with obtaining financing for the Initial Proposal, he intends to form the Xxxxxx Group (as defined below) that would include other members of management and shareholders of the Company, and which would be considered a "person" within the meaning of Part 13 of the Texas Business Corporations Act (the "TBCA"). The acquisition by the Xxxxxx Group of beneficial ownership of voting shares of the Company representing 20% or more of the outstanding voting shares of the Company, will result in the Xxxxxx Group and each of its members being considered an "affiliated shareholder" within the meaning of Part 13 of the TBCA. Xx. Xxxxxx requested that the Special Committee and the Board of Directors of the Company adopt resolutions and take such other actions as may be necessary to render the special shareholder vote required by Article 13.03A(2) of the TBCA inapplicable to any business combination between the Company and any entity formed to pursue the Initial Proposal (the "Approval").

After consultation and consideration, the Special Committee has determined that it is in the best interests of the shareholders of the Company to (a) solicit alternative proposals from other bidders related to the sale of the Company or its assets (each, a "Proposal") and (b) grant the Approval in order to encourage the Xxxxxx Group to submit a definitive proposal (each such proposal, a "Xxxxxx Group Proposal") that, if approved by the Special Committee could be presented to the shareholders of the Company for their approval upon receipt of the same shareholder vote as would be required to approve a competing Proposal, provided that Xx. Xxxxxx and certain other members of any group of which he is a member agree to take or refrain from taking certain actions, as set forth herein. For purposes of this Agreement, the "Xxxxxx Group" shall have the meaning given to such term in the resolutions of the Special Committee and the Board of Directors of the Company granting the Approval.

2. Representations by Xx. Xxxxxx. Xx. Xxxxxx hereby represents and warrants to the Company as follows:

(a) Share Ownership. Neither Xx. Xxxxxx nor any group of which he has at any time been a member is an "affiliated shareholder" of the Company or an "affiliate" or "associate" of an "affiliated shareholder," in each case within the meaning of Part 13 of the TBCA. As of the date hereof, Xx. Xxxxxx is not a member of any group (within the meaning of Part 13 of the TBCA) with respect to the voting shares of the Company.

(b) Capacity; Enforceability. Xx. Xxxxxx has the power and capacity to execute, deliver and perform his obligations under this Agreement. This Agreement constitutes the legal, valid and binding obligation of Xx. Xxxxxx, enforceable against him in accordance with its terms.

(c) No Conflict. The execution and delivery of this Agreement by Xx. Xxxxxx and his performance of his obligations hereunder will not conflict with or constitute a breach or default under, any contract, agreement, arrangement or understanding to which he is a party or by which he is bound.

3. Covenants and Agreements of Xx. Xxxxxx and the Joinder Parties. In consideration of the granting of the Approval by the Special Committee and the Board of Directors of the Company, Xx. Xxxxxx and each Joinder Party hereby covenants and agrees with the Company as follows:

(a) No Voting Agreement. Neither Xx. Xxxxxx nor any Joinder Party shall (i) enter into or consent to any agreement, arrangement or understanding (whether written or verbal, express or implied, by proxy or otherwise) with any other person or entity, or any group (other than any proxy or consent solicited by or on behalf of the Special Committee), relating to the voting of any shares of capital stock of the Company beneficially owned by him with respect to any Proposal other than a Xxxxxx Group Proposal, that is approved by the Special Committee (a "Competing Proposal"), including any agreement, arrangement or understanding to vote against, oppose, or abstain from voting on, any Competing Proposal (whether at a meeting or by written consent in lieu of a meeting) or to attend, or refrain from attending, any meeting of shareholders at which a Competing Proposal is to be acted upon or (ii) directly or indirectly, encourage or solicit votes with respect to any Competing Proposal.

(b) Withdrawal; Disbandment of Group. Xx. Xxxxxx and each Joinder Party shall submit the Xxxxxx Group Proposal to the Special Committee only in accordance with bid procedures established by the Special Committee's financial advisor. In the event the requisite shareholder approval is obtained for a Competing Proposal or the Special Committee abandons efforts to seek Proposals, Xx. Xxxxxx and the Joinder Parties shall, no later than seven business days after receipt of written notice from the Special Committee of such approval or abandonment, take all actions necessary to disband the Xxxxxx Group and file an amendment to the Xxxxxx Group's Schedule 13D, which shall reflect the disbandment of the Xxxxxx Group. The Company, Xx. Xxxxxx and each Joinder Party hereby acknowledge and agree that upon such disbanding of the Xxxxxx Group, the Xxxxxx Group shall no longer exist as a "person" for purposes of Part 13 of the TBCA and that, therefore, no person or entity may thereafter be deemed an "affiliate" or "associate" of the Xxxxxx Group. If, subsequent to the Xxxxxx Group beneficially owning 20% of the outstanding voting shares, changes in beneficial ownership result in the Xxxxxx Group dropping below 20%, then neither Xx. Xxxxxx nor any Joinder Party shall acquire beneficial ownership of voting shares of the Company exceeding 20% of the outstanding voting shares without another written approval by the Board of Directors of the Company or the Special Committee.

(c) Joinder. Any person or entity that becomes a member of the Xxxxxx Group and who was at the time of the Initial Proposal, or who is or becomes an officer, director or employee of the Company, shall concurrently agree to be bound by the terms of this Agreement and will confirm such person's understanding that it is bound by the Confidentiality Agreement dated September 12, 2002, between the Company and Xx. Xxxxxx (the "Confidentiality Agreement"), by executing a Joinder Agreement substantially in the form annexed hereto as Exhibit A (the "Joinder Agreement"). Further, each entity formed or used in connection with the Initial Proposal or any Xxxxxx Group Proposal, including any entity formed to be a constituent to any business combination with the Company, shall, concurrently with its formation or before any such use, agree to be bound by the terms of this Agreement and the Confidentiality Agreement by executing a Joinder Agreement.

(d) Filing of Reports. Xx. Xxxxxx shall timely make all filings with the Securities and Exchange Commission required by Section 13 of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (the "1934 Act") regarding the voting shares of the Company beneficially owned by Xx. Xxxxxx and any group (within the meaning of the 0000 Xxx) of which he is a member, and the information set forth therein shall be true, correct and complete in all material respects.
