SYNTROLEUM CORPORATION
2005 STOCK INCENTIVE PLAN
EMPLOYEE RESTRICTED STOCK AWARD AGREEMENT

THIS AGREEMENT (“Agreement”), made as of the 12th day of July 2007 (the “Grant Date”), evidences an award by Syntroleum Corporation, a Delaware corporation (the “Company”) to Karen L. Gallagher (the “Grantee”) pursuant to the 2005 Stock Incentive Plan (the “Plan”). Capitalized terms used and not otherwise defined herein shall have the meaning ascribed thereto in the Plan.

1. Grant of Restricted Stock Award. Effective as of the Grant Date, pursuant to Section 8 of the Plan, the Company has awarded to the Grantee a Restricted Stock Award with respect to one hundred sixty-five thousand (165,000) shares of Common Stock, subject to the conditions and restrictions set forth below and in the Plan (the “Restricted Stock”).

2. Restrictions. The Restricted Stock granted hereunder to the Grantee may not be sold, assigned, transferred, pledged or otherwise encumbered from the Grant Date until the date that the Grantee obtains a vested right to the shares (and the restrictions thereon terminate) in accordance with the provisions of this Section 2. Provided that the Grantee has been in continuous service as an employee since the Grant Date as of the date the relevant portion of the Restricted Shares are scheduled to vest and that Grantee has completed the probationary period set forth in her Employment Agreement dated June 13, 2007 and remains in the employment of the Company, the Grantee shall have a vested right to a number of shares, as described below, out of the Restricted Stock grant described in Section 1, above, upon the completion of each of the following events, as determined by the Nominating and Compensation Committee of the Company’s Board of Directors (the “Committee”) in its discretion:

(a)

upon the date of execution of definitive agreements for the provision of feedstock to and creation of a venture to construct and operate a plant of capacity to produce at least 3000 barrels per day of sales product (the “Plant”) with an entity acceptable to the Company, Grantee shall have a vested right to fifteen thousand (15,000) of the shares of Restricted Stock; and

(b)

upon the date of closing of the financing for the construction of the Plant, Grantee shall have a vested right to fifty thousand (50,000) of the shares of Restricted Stock; and

(c)

upon the date of the groundbreaking of the above Plant’s construction, Grantee shall have a vested right to an additional fifty thousand (50,000) of the shares of Restricted Stock; and

(d)

upon the date of completion of start-up operations and commencement of the Plant’s commercial operations, Grantee shall have a vested right to the remaining fifty thousand (50,000) of the shares of Restricted Stock.

Notwithstanding the foregoing:

(a)

Grantee shall have a vested right to all of the Restricted Stock upon a termination of Grantee’s service as an employee due to death, disability or retirement; and

(b)

Grantee shall have a vested right to all of the Restricted Stock upon a Change in Control

To the extent any of the shares of Restricted Stock have not vested as of June 11, 2017, such unvested shares shall be forfeited.

The period of time between the Grant Date and the date that the Grantee obtains a vested right to the Restricted Stock shall be referred to herein as the “Restricted Period” as to those shares. In the event that any day on which the Grantee would otherwise obtain a vested right to the Restricted Stock is a Saturday, Sunday or holiday, the Grantee shall instead obtain that vested right on the first business day immediately following such date. Authorized leaves of absence from the Company shall not constitute a termination of employment for purposes of this Agreement. For purposes of this Agreement, an authorized leave of absence shall be an absence while Grantee is on military leave, sick leave, or other bona fide leave of absence so long as Grantee’s right to employment with the Company is guaranteed by statute, contract, or company policy. Whether the Grantee’s employment terminates due to “disability” or “retirement” for purposes of this Agreement will be determined by the the “Committee” in its discretion.

3. Forfeiture. If Grantee’s employment terminates under circumstances other than those provided in Section 2 prior to all or a portion of the Restricted Stock having become vested pursuant to the provisions of Section 2, the Grantee shall forfeit all right to the Restricted Stock which has not yet vested as of the date of termination of employment. Such forfeiture shall apply to Beneficiaries (as defined below) as well as the Grantee.

4. Share Issuance. The Company will issue to Grantee stock certificates evidencing the shares of Restricted Stock, which certificates will be registered in the name of Grantee and will bear an appropriate legend referring to the terms, conditions, and restrictions applicable to the Restricted Stock, substantially in the following form:

The transferability of this certificate and the shares of Common Stock represented hereby are subject to the terms, conditions and restrictions (including forfeiture) contained in the Employee Restricted Stock Award Agreement, effective as of June 11, 2007, between Syntroleum Corporation and the registered owner hereof. Copies of such Agreement are on file in the offices of Syntroleum Corporation, 4322 South 49th West Avenue, Tulsa, Oklahoma, 74107

The certificates evidencing the shares of Restricted Stock shall be held in custody by the Company or, if specified by the Committee, by a third party custodian or trustee, until the restrictions on such shares shall have lapsed, and, as a condition of this award of Restricted Stock, the Grantee shall deliver a stock power, duly endorsed in blank, relating to the shares of Restricted Stock. Upon the vesting and expiration of the restrictions as to any portion of the Restricted Stock, the Company will cause a new certificate evidencing such number of shares of Common Stock to be delivered to the Grantee, or in the case of his death to his Beneficiary, free of the legend regarding transferability; provided that the Company shall not be obligated to issue any fractional shares of Common Stock.

5. Beneficiary Designations. Pursuant to Section 10 of the Plan, the Grantee shall file with the Company on such form as may be prescribed by the Company, a designation of one or more beneficiaries and, if desired, one or more contingent beneficiaries (each referred to herein as a “Beneficiary”) to whom shares of Common Stock otherwise due the Grantee under the terms of this Agreement shall be distributed in the event of the death of the Grantee. The Grantee shall have the right to change the Beneficiary or Beneficiaries from time to time; provided, however, that any change shall not become effective until received in the Grantee’s handwriting by the Committee. If there is no effective Beneficiary designation on file at the time of the Grantee’s death, or if the designated Beneficiary or Beneficiaries have all predeceased such Grantee, the payment of any remaining benefits under this Agreement shall be made to the personal representative or executor of the Grantee’s estate. If one or more but not all the Beneficiaries have predeceased such Grantee, the benefits under this Agreement shall be paid according to the Grantee’s instructions in his designation of Beneficiaries. If the Grantee has not given instructions, or if the instructions are not clear, the benefits under this Agreement which would have been paid to the deceased Beneficiary or Beneficiaries will be paid to the personal representative or executor of Grantee’s estate.

6. Nonalienation of Benefits. Except as contemplated by Section 5 above, no right or benefit under this Agreement shall be subject to transfer, anticipation, alienation, sale, assignment, pledge, encumbrance or charge, whether voluntary, involuntary or by operation of law, and any attempt to transfer, anticipate, alienate, sell, assign, pledge, encumber or charge the same shall be void. No right or benefit hereunder shall in any manner be liable for or subject to any debts, contracts, liabilities or torts of the person entitled to such benefits. If the Grantee or the Grantee’s Beneficiary hereunder shall become bankrupt or attempt to transfer, anticipate, alienate, assign, sell, pledge, encumber or charge any right or benefit hereunder, other than as contemplated by Section 5 above, or if any creditor shall attempt to subject the same to a writ of garnishment, attachment, execution, sequestration or any other form of process or involuntary lien or seizure, then such right or benefit shall cease and terminate.

7. Prerequisites to Benefits. Neither the Grantee, nor any person claiming through the Grantee, shall have any right or interest in Restricted Stock awarded hereunder, unless and until all the terms, conditions and provisions of this Agreement and the Plan which affect the Grantee or such other person shall have been complied with as specified herein.

8. Issuance and Delivery of Shares. The Company shall not be obligated to issue or deliver any shares of Common Stock if counsel to the Company determines that such issuance or delivery would violate any applicable law or any rule or regulation of any United States governmental authority or any rule or regulation of, or agreement of the Company with, any securities exchange or association upon which the Common Stock is listed or quoted. If necessary to comply with any such law, rule, regulation or agreement, the Company shall in no event be obligated to take any affirmative action in order to cause the issuance or delivery of shares of Common Stock. If within 45 calendar days of vesting all or portion of the Restricted Stock the Company does not issue the Common Stock due Employee, Company shall pay to Employee, at Employee’s option, the equivalent value of the vested Restricted Stock. Equivalent cash values shall be calculated as the highest five day rolling average price from the vesting date to the vesting date plus 45 calendar days.

9. Rights as a Stockholder. During the period in which the restrictions provided herein are applicable to the Restricted Stock, the Grantee shall have the right to vote the shares of Restricted Stock and to receive any cash dividends paid with respect thereto unless and until forfeiture thereof. Any dividend or distribution payable with respect to shares of Restricted Stock that shall be paid or distributed in shares of Common Stock shall be subject to the same restrictions provided for herein, and the shares so paid or distributed shall be deemed Restricted Stock subject to all terms and conditions herein. Any dividend or distribution (other than cash or Common Stock) payable or distributable on shares of Restricted Stock, unless otherwise determined by the Committee, shall be subject to the terms and conditions of this Agreement to the same extent and in the same manner as the Restricted Stock is subject; provided that the Committee may make such modifications and additions to the terms and conditions (including restrictions on transfer and the conditions to the timing and degree of lapse of such restrictions) that shall become applicable to such dividend or distribution as the Committee may provide in its absolute discretion.

10. Taxes. The Company shall have the right to withhold an appropriate amount of cash or number of shares of Common Stock, or combination thereof, for payment of taxes or other amounts required by law or to take such action as may be necessary in the opinion of the Company to satisfy all obligations for withholding of taxes. Withholding may be satisfied by the transfer to the Company of shares of Common Stock theretofore owned by the Grantee, subject to such terms and conditions as the Committee shall prescribe.

11. Adjustments. As provided in the Plan, certain adjustments may be made to the Restricted Stock upon the occurrence of events or circumstances described in Section 19 of the Plan.
