PAR PETROLUEM CORPORATION

NAV UNITS PLAN

1. Purpose of the Plan

The purpose of the Par Petroleum Corporation NAV Units Plan (the “Plan”) is to further the long-term growth in Net Asset Value of Par Petroleum Corporation (the “Company”) by offering long-term incentives in addition to current compensation to those Employees of the Company and the Company’s Affiliates who will be largely responsible for such growth of the Company and the Company’s Affiliates. Terms not defined in the text of this Plan shall have the meaning as provided in the Par Petroleum 2012 Long Term Incentive Plan (effective December 20, 2012) (the “Incentive Plan”) or as specifically provided in Appendix A. In addition, any payments or shares issued hereunder shall be subject to the terms of the Incentive Plan provided that no acceleration of payment or vesting shall occur unless it is specified in this Plan.

2. Administration of the Plan

The Plan shall be administered by the compensation committee of the board of directors of the Company (the “Committee”). The Committee shall have exclusive power to select the Employees to be granted Awards of Units, to determine the number of Units to be granted to each Employee selected, to determine the time or times when Units will be granted, to determine the Base Amount and Net Asset Value, to determine the time or times, and the conditions, subject to which any Awards may become payable and to determine all other terms and conditions of Awards and to interpret and construe the Plan and provide any omitted terms of this Plan. Decisions and determinations by the Committee shall be final and binding upon all persons, including Participants and other Employees. The Committee shall have the authority to establish and revise rules and regulations relating to the Plan, and to make any other determinations that it believes necessary or advisable for the administration of the Plan.

3. Participation

Participants in the Plan shall be selected by the Committee in its sole discretion from Employees. An Employee may be granted more than one Award of Units under this Plan.

4. Award of Units; Voting Rights

Awards under this Plan shall be granted to a Participant in the form of Units, which shall be credited to an Account to be maintained for such Participant. There shall be no separate fund or trust for the Account or any Awards of Units under this Plan and all Accounts shall be subject to the Company’s creditors claims. The Participant shall have no right to the Account or any right to transfer the Account. Each Unit shall have a value as described in Section 8 hereof. An Award of Units shall not entitle the recipient to hold or exercise any voting rights, rights to dividends or any other rights of a stockholder of the Company or any Company Affiliate.

5. Time of Grants of Awards

This Plan shall be effective for all grants of Units on or after June 12, 2014 when the Plan is approved by Board. The Committee may grant Awards of Units at any time in its sole discretion.

6. Right to Payment for Units

No Units will be vested and payable and no transfer of an Award can be made until the earlier of a Change in Control or March 1, 2016. If a Participant’s employment or other Service with the Company or a Company Affiliate is terminated for any reason after the Grant Date (as defined below) and prior to the earlier of a Change in Control or March 1, 2016, then such Participant shall not be entitled to any payment hereunder and such Participant’s interest in any and all Units shall be void and terminated.

7. Form and Timing of Payment

Units will be paid within 60 days of the earlier of a Change in Control or March 1, 2016, and amounts payable in connection with a Change in Control shall be cash, but amounts paid on March 1, 2016 maybe paid in cash or Stock as determined by the Committee in its sole discretion. The amount to be paid shall be calculated in accordance with Section 8 and will not include any interest, dividends or earnings of any kind.

8. Value of Units

The value of one Unit shall be equal to the Net Asset Value, as determined by the Committee in its sole discretion, minus the Base Amount.

The computation of the value of any Unit shall be made by the Committee, in its sole discretion and the Committee’s computation of Base Amount and value of a Unit, if any, shall be conclusive and binding on all parties (including each Participant).

9. Vesting

An Award will only be payable and become vested if the Participant is continuously in Service with the Company or a Company Affiliate from the date of the grant of the Award as specified in the Award (“Grant Date”) through the earlier of a Change in Control or March 1, 2016.

10. No Guarantee of Employment or Service

The Award of Units pursuant hereto shall not confer upon the Participant any right to employment or other Service with the Company or a Company Affiliate, nor shall it interfere with any right the Company or a Company Affiliate would otherwise have to terminate such Participant’s employment or other service at any time, with or without Cause.

The Award shall not entitled the Participant to become a stockholder, or to otherwise hold or exercise any voting rights, right to distributions, or other rights of a stockholder.

11. Termination or Amendment of Units Award

In addition to termination by forfeiture as a result of termination of Service prior to vesting, the Committee may terminate or amend an Award with the written consent of a Participant holding such Award granted to him or her under the Plan; provided, however, that the Participant’s written consent will not be required if the amendment is for the purposes of compliance with Code Section 409A or other applicable law. In the event Units are forfeited in accordance with the Plan or the Award, all rights of the former holder of such terminated Units in respect of such terminated Units Award shall terminate.
