(a)    Subject to Paragraph 3, this Option shall become exercisable in three cumulative annual installments, as follows:

provided, however, that the Participant must be in continuous Employment from the Grant Date through the applicable date of exercisability of each installment in order for the applicable portion of the Option to become exercisable with respect to additional shares of Common Stock on such date. If the Employment of the Participant is terminated for any reason other than death or Retirement, any Option Shares that are not exercisable as of the date of such termination of Employment shall be forfeited to the Corporation.

This Award is conditioned upon and subject to the Participant accepting the Award by signing and delivering to the Corporation this Award Agreement, or otherwise electronically accepting the Award in such manner as the Committee may in its discretion determine, no later than 11 months after the Grant Date. If the Participant does not timely accept this Award, all of the Participant’s rights under the Option shall be forfeited and the Award shall be canceled.

6.    Conditions Precedent. This Paragraph 6 shall apply to this Award notwithstanding any other provision of this Award Agreement to the contrary. The Participant’s services to the Corporation and its Subsidiaries are unique, extraordinary and essential to the business of the Corporation and its Subsidiaries, particularly in view of the Participant’s access to the Corporation’s or its Subsidiaries’ confidential information and trade secrets. Accordingly, in consideration of this Award Agreement and by accepting this Award, the Participant agrees that in order to otherwise vest in any right to any portion of the Option under Paragraph 2, the Participant must satisfy the following conditions to and including the vesting date for each applicable annual installment or other applicable portion of the Option under the vesting provisions in Paragraph 2:

(a)    The Participant agrees that the Participant will not, without the prior written approval of the Board, at any time during the term of the Participant’s Employment and for a period of one year following the date on which the Participant’s Employment terminates (the “Restricted Period”), directly or indirectly, serve as an officer, director, owner, contractor, consultant, or employee of any the following organizations (or any of their respective subsidiaries or divisions): BP plc, Chevron Corporation; ExxonMobil Corporation, HollyFrontier Corporation; PBF Energy Inc.; Phillips 66; Valero Energy Corporation; Buckeye Partners, L.P.; DCP Midstream Partners, L.P; Enterprise Product Partners; Gas; Genesis Energy, L.P. ; Holly Energy Partners L.P.; Magellan Midstream Partners, L.P.; Phillips 66 Partners, L.P.; Plains All American Pipeline L.P.; Western Gas Equity Partners, or otherwise engage in any business activity directly or indirectly competitive with the business of the Corporation or any of its Subsidiaries as in effect from time to time.

(b)    The Participant agrees that during the term of the Participant’s Employment and for a period of one year following the date on which the Participant’s Employment terminates, the Participant will not, alone or in conjunction with another party, hire, solicit for hire, aid in or facilitate the hire, or cause to be hired, either as an employee, contractor or consultant, any individual who is currently engaged, or was engaged at any time during the six month period prior such event, as an employee, contractor or consultant of the Corporation or any of its Subsidiaries.

(c)    The Participant agrees that the Participant may not, either during the Participant’s Employment or thereafter, make or encourage others to make any public statement or release any information or otherwise engage in any conduct that is intended to, or reasonably could be foreseen to, embarrass, criticize or harm the reputation or goodwill of the Corporation or any of its Subsidiaries, or any of their employees, directors or shareholders; provided that this shall not preclude the Participant from reporting to the Corporation’s management or directors or to the government or a regulator conduct the Participant believes to be in violation of the law or the Corporation’s Code of Business Conduct or responding truthfully to questions or requests for information to the government, a regulator or in a court of law in connection with a legal or regulatory investigation or proceeding.

(d)    The Participant agrees and understands that the Corporation and its Subsidiaries own and/or control information and material which is not generally available to third parties and which the Corporation or its Subsidiaries consider confidential, including, without limitation, methods, products, processes, customer lists, trade secrets and other information applicable to its business and that it may from time to time acquire, improve or produce additional methods, products, processes, customers lists, trade secrets and other information (collectively, the “Confidential Information”). The Participant acknowledges that each element of the Confidential Information constitutes a unique and valuable asset of the Corporation and its Subsidiaries, and that certain items of the Confidential Information have been acquired from third parties upon the express condition that such items would not be disclosed to the Corporation or a Subsidiary and the officers and agents thereof other than in the ordinary course of business. The Participant acknowledges that disclosure of the Confidential Information to and/or use by anyone other than in the Corporation’s or its Subsidiaries’ ordinary course of business would result in irreparable and continuing damage to the Corporation and its Subsidiaries. Accordingly, the Participant agrees to hold the Confidential Information in the strictest secrecy, and covenants that, during the term of the Participant’s Employment or at any time thereafter, the Participant will not, without the prior written consent of the Board, directly or indirectly, allow any element of the Confidential Information to be disclosed, published or used, nor permit the Confidential Information to be discussed, published or used, either by Participant or by any third parties, except in effecting the Participant’s duties for the Corporation and its Subsidiaries in the ordinary course of business.

(e)    The Participant agrees that in addition to the forfeiture provisions otherwise provided for in this Award Agreement, upon the Participant’s failure to satisfy in any respect of any of the conditions described in Paragraphs 6(a), (b), (c) or (d), any unvested and unexercised portion of the Option provided for under this Award at the time of such breach shall be forfeited, and the rights of the Participant and the obligations of the Corporation under this Award Agreement shall be satisfied in full, in each case to the extent permitted by applicable law.
