Capitalized terms not defined below shall have the meanings set forth in the Plan.

Authorized Party means the person who is authorized to approve an Award, exercise discretion or take action under the Administrative Procedure for the Restricted Stock Program and pursuant to the Program. With regard to Senior Officers, the Committee is the Authorized Party. With regard to other Employees, the Chief Executive Officer, acting as the Special Equity Award Committee of the Board of Directors of the Company, is the Authorized Party, although the Committee may act concurrently as the Authorized Party.

Award means any Restricted Stock Units granted to an Employee pursuant to such applicable terms, conditions, and limitations as the Authorized Party may establish in order to fulfill the objectives of the Program.

Change of Control has the meaning set forth in Attachment A to these Terms and Conditions.

Committee means the Human Resources and Compensation Committee of the Board of Directors of the Company, or any successor committee to it.

Company means ConocoPhillips, a Delaware corporation.

Designated Date means the date set forth on the Employee’s Award Summary as the Designated Date.

Disability means a disability for which the employee in question has been determined to be entitled to either (i) benefits under the applicable plan of long-term disability of the Company or its subsidiaries or (ii) disability benefits under the Social Security Act. In the absence of any such determination, the Authorized Party may make a determination that the employee has a Disability.

Fair Market Value means, as of a particular date, the mean between the highest and lowest sales price per share of such Stock on the consolidated transaction reporting system for the principal national securities exchange on which shares of Stock are listed on that date, or, if there shall have been no such sale so reported on that date, on the next preceding date on which such a sale was so reported, or, at the discretion of the Committee, the price prevailing on the exchange at a designated time.

Grant Price means the Fair Market Value for one share of Stock as of the date of the grant of an Award. Grant price is not adjusted for any restrictions applicable to the Award.

Layoff means an applicable Termination of Employment due to layoff under the ConocoPhillips Severance Pay Plan, the ConocoPhillips Executive Severance Plan, or the ConocoPhillips Key Employee Change in Control Severance Plan, or layoff or redundancy under any similar layoff or redundancy plan which the Company or its subsidiaries may adopt from time to time. If all or any portion of the benefits under the redundancy or layoff plan are contingent on the employee’s signing a general release of liability, such Termination shall not be considered as a “Layoff” for purposes of this Award unless the employee executes and does not revoke a general release of liability, acceptable to the Company, under the terms of such layoff or redundancy plan. In order to be considered a layoff for purposes of this Award, the Termination of Employment must also be considered a Separation from Service.

Participating Company includes ConocoPhillips and its 100% owned subsidiaries, including both those directly owned and those owned through subsidiaries, whose participation has been approved by the Authorized Party.

(b) such Person or any of such Person’s Affiliates and Associates, directly or indirectly, has the right or obligation to acquire such securities (whether such right or obligation is exercisable or effective immediately or only after the passage of time or the occurrence of an event) pursuant to any agreement, arrangement or understanding (whether or not in writing) or upon the exercise of conversion rights, exchange rights, other rights, warrants or options, or otherwise; provided, however, that a Person shall not be deemed the Beneficial Owner of, or to “beneficially own,” (i) securities tendered pursuant to a tender or exchange offer made by such Person or any of such Person’s Affiliates or Associates until such tendered securities are accepted for purchase or exchange or (ii) securities issuable upon exercise of Exempt Rights; or

(c) such Person or any of such Person’s Affiliates or Associates (i) has any agreement, arrangement or understanding (whether or not in writing) with any other Person (or any Affiliate or Associate thereof) that beneficially owns such securities for the purpose of acquiring, holding, voting (except as set forth in the proviso to subsection (a) of this definition) or disposing of such securities or (ii) is a member of a group (as that term is used in Rule 13d-5(b) of the General Rules and Regulations under the Exchange Act) that includes any other Person that beneficially owns such securities;
