AMENDMENT TO RESTRICTED STOCK AWARD AGREEMENT




THIS document is an amendment (the “Amendment”) to an existing restricted stock agreement dated
April 24, 2007 (the “Agreement”) between Syntroleum Corporation, (“Syntroleum”) and Gary Roth (the
“Grantee”) entered into pursuant to the 2005 Stock Incentive Plan (the “Plan”).



The existing terms and definitions in the Agreement and the Plan are confirmed and retained, except
that the number of shares of Restricted Stock subject to the Agreement as described in Section 2 of
the Agreement is adjusted and increased as described below. Additional shares of Restricted Stock
shall be issued to reflect the following changes in the Agreement (the “Additional Shares”).
Alternatively, new shares of Restricted Stock may be issued and the existing shares of Restricted
Stock canceled in order to reflect the changes provided for in this Amendment.



1. Grant of Restricted Stock Award. Effective as of the Grant Date, pursuant to
Section 8 of the Plan, the Company awarded to the Grantee a Restricted Stock Award with respect to
five hundred thousand (500,000) shares of Common Stock, subject to the conditions and restrictions
set forth below and in the Plan (the “Restricted Stock”). Effective as of the date of the
Amendment, the grant has been increased by 1 million shares (the “Additional Shares”) to 1.5
million shares of Restricted Stock as described below.



2. Restrictions. The Restricted Stock granted 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 shares of Restricted
Stock are scheduled to vest, 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 certified to the Board of Directors by 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 3,000 barrels per day of sales product (the “Plant”), Grantee
shall have a vested right to one hundred thousand (100,000) shares of Restricted
Stock; and
