On February 18, 2014, WPX Energy, Inc. (the “Company” or “WPX Energy”) eliminated the position of Senior Vice President – Business Development and Land effective as of May 2, 2014 (the “Termination Date”). The position is currently held by Neal A. Buck, who will remain an employee of the Company at his current salary until the Termination Date, and will be responsible for such specific duties as may be assigned to him by the Company’s Chief Executive Officer.

In connection with its decision to eliminate the position of Senior Vice President – Business Development and Land, the Company has determined that certain severance arrangements for Mr. Buck are appropriate. Consequently, the Company and Mr. Buck have entered into a severance agreement, dated as of February 18, 2014 (the “Severance Agreement”), which is being filed as Exhibit 10.1 to this Current Report. The Severance Agreement provides that Mr. Buck will be entitled to (i) continued eligibility for payment under the Company’s 2013 Annual Incentive Plan, payable in 2014, and (ii) a severance payment of up to $250,000, depending on an assessment of Mr. Buck’s performance of the duties assigned to him. With respect to equity awards the Company has granted to Mr. Buck, (i) all stock options previously granted remain exercisable subject to the terms of the Company’s applicable equity incentive compensation plans (“Equity Plans”), (ii) all time-based restricted stock units shall become fully vested on the Termination Date subject to the terms of the Company’s applicable Equity Plans, and shall be payable within five days of October 31, 2014, and (iii) all performance-based restricted stock units shall become fully vested on a pro rata basis through the Termination Date subject to the terms of the Company’s applicable Equity Plans. All incentive compensation paid to Mr. Buck shall remain subject to the Company’s standard recoupment or “clawback” policy, as described in the Company’s most recent proxy statement to stockholders.

All payments to which Mr. Buck is entitled under the Severance Agreement are conditioned on his execution and delivery of a general release of claims against the Company. The Severance Agreement also includes a number of covenants to which Mr. Buck has agreed, including but not limited to (i) maintaining the confidentiality of proprietary Company information, (ii) non-competition in the business of exploration and production of oil and natural gas until October 31, 2014, (iii) non-solicitation of Company employees, and (iv) cooperation with the Company in the event of litigation against the Company by a third party.

The foregoing summary of the Severance Agreement is qualified in its entirety by reference to the full text of the Severance Agreement that is included in this Current Report as Exhibit 10.1 and is incorporated herein in its entirety.
