FORM OF STOCK AWARD

AGREEMENT FOR EMPLOYEES UNDER THE

XTO ENERGY INC. 2004 STOCK INCENTIVE PLAN,

AS AMENDED AND RESTATED AS OF MAY 20, 2008

THIS AGREEMENT is entered into this 17th day of November, 2009, between XTO Energy Inc., a Delaware corporation (the “Company”), and              (“Grantee”), pursuant to the provisions of the XTO Energy Inc. 2004 Stock Incentive Plan, as Amended and Restated as of May 20, 2008 (the “Plan”). The Compensation Committee of the Board of Directors of the Company (the “Committee”) has determined that Grantee is eligible to be a participant in the Plan and, to carry out its purposes, has this day authorized the grant, pursuant to the Plan, of the stock award set forth below to Grantee.

NOW, THEREFORE, in consideration of the mutual covenants herein contained, the parties do hereby agree as follows:

1. Grant of Stock Award. Subject to all of the terms, conditions and provisions of the Plan and of this Agreement, the Company hereby grants to Grantee under Section 10 of the Plan              shares of the common stock of the Company, par value one cent ($0.01) per share (the “Common Stock”), which shares will consist of authorized but unissued shares or issued shares reacquired by the Company. Such shares are being issued as a stock award in the form of performance shares under the Plan.

2. Vesting. Fifty percent (50%) of the performance shares granted herein will vest when the Common Stock closes on the New York Stock Exchange at or above each of the following levels: $50.00 and $55.00 per share; provided, however, that if prior to the performance shares granted herein vesting as a result of the Common Stock’s closing at or above one or both price levels, the Company announces that it has entered into a definitive agreement with respect to any transaction that could result in a Change in Control (as defined in the Plan) in which the Company is not the surviving public company, the unvested performances shares shall not, except as provided below, vest as a result of any closing prices of the Common Stock on any trading day from and after such announcement. In the event of any such Change in Control, the unvested performance shares shall vest on the earlier of the first anniversary of the closing of the transaction resulting in the Change in Control or on the first trading day on which the Common Stock closes at or above the applicable price levels after two full trading days following the announcement that the definitive agreement relating to the Change in Control transaction has been terminated. If the Common Stock is not listed on the New York Stock Exchange, then any reference in this Agreement to the New York Stock Exchange will be deemed to be the principal securities market on which the Common Stock is traded or quoted.

3. Grantee’s Agreement. Grantee expressly and specifically agrees that:

4. Term. Any performance shares which remain unvested on the seventh anniversary of the date of this Agreement will be canceled, will not vest, and will be returned to the Company.

5. Death or Disability. Upon death of Grantee, or upon termination of Grantee’s employment by reason of permanent disability (as determined by the Committee), all unvested performance shares granted herein will immediately vest.

6. Other Terms, Conditions and Provisions. As noted above, just as with all other Awards granted to Grantee under the Plan, the performance shares herein granted by the Company to Grantee are granted subject to all of the terms, conditions and provisions of the Plan, including without limitation the Committee discretion reserved in the adjustment provisions of Sections 5(f) and 19 of the Plan. Grantee

hereby acknowledges receipt of a copy of the Plan and Plan prospectus and hereby consents to receive any updates to the Plan or Plan prospectus electronically. The parties agree that the entire text of the Plan is incorporated by reference as if copied herein. Reference is made to the Plan for a full description of the rights of Grantee and the limitations thereon set forth in the terms, conditions and provisions of the Plan applicable to the performance shares granted herein. If any of the provisions of this Agreement or of the Management Plan, the Employee Plan or any other compensation or insurance plan of the Company vary from or are in conflict with the Plan, the provisions of the Plan will be controlling.

7. Non-Transferability. The performance shares granted herein are not transferable or assignable by Grantee.

8. Rights as a Stockholder. Grantee will have the voting, dividend, and other rights of stockholders of the Company prior to and upon vesting of the performance shares. If the performance shares are canceled, all such rights will then be canceled.

9. No Employment Commitment. Grantee acknowledges that neither the grant of performance shares nor the execution of this Agreement by the Company will be interpreted or construed as imposing upon the Company any obligation to retain Grantee’s services for any stated period of time, which employment will continue to be at the pleasure of the Company at such compensation as it determines, unless otherwise provided in a written employment agreement signed by the Company and Grantee.

IN WITNESS WHEREOF, this Agreement is executed and entered into effective on the day and year first above expressed.
