 4. Offering Periods. The Plan shall be implemented by consecutive Offering Periods with a new Offering Period commencing on the first Trading Day on or after May 1 and November 1 of each year, or on

future offerings without stockholder approval if such change is announced prior to the scheduled beginning of the first Offering Period to be affected thereafter. 
 5. Participation. An Employee who is eligible to participate in the Plan pursuant to Section 3 may become a participant by (i) submitting to the Company’s payroll office (or its designee), on or
before a date prescribed by the Administrator prior to an applicable Enrollment Date, a properly completed subscription agreement authorizing payroll deductions in the form provided by the Administrator for such purpose, or (ii) following an
electronic or other enrollment procedure prescribed by the Administrator. 
 6. Payroll Deductions. 
 (a) At the time a participant enrolls in the Plan pursuant to Section 5, he or she shall elect to have payroll deductions made on each payday during
the Offering Period in an amount not exceeding 15% of the Compensation which he or she receives on each such payday. 
 (b) Payroll
deductions authorized by a participant shall commence on the first payday following the Enrollment Date and shall end on the last payday in the Offering Period to which such authorization is applicable, unless sooner terminated by the participant as
provided in Section 10. 
 (c) All payroll deductions made for a participant shall be credited to his or her account under the Plan and
shall be withheld in whole percentages only. A participant may not make any additional payments into such account. 
 (d) A participant may
discontinue his or her participation in the Plan as provided in Section 10, or may change the rate of his or her payroll deductions during the Offering Period by (i) properly completing and submitting to the Company’s payroll office
(or its designee), on or 

  

 -4- 

 
before a date prescribed by the Administrator prior to an applicable Exercise Date, a new subscription agreement authorizing the change in payroll deduction
rate in the form provided by the Administrator for such purpose, or (ii) following an electronic or other procedure prescribed by the Administrator; provided, however, that a participant may only make one payroll deduction change during each
Offering Period. If a participant has not followed such procedures to change the rate of payroll deductions, the rate of his or her payroll deductions shall continue at the originally elected rate throughout the Offering Period and future Offering
Periods (unless terminated as provided in Section 10). The Administrator may, in its sole discretion, limit the nature and/or number of payroll deduction rate changes that may be made by participants during any Offering Period. Any change in
payroll deduction rate made pursuant to this Section 6(d) shall be effective as of the first full payroll period following five (5) business days after the date on which the change is made by the participant (unless the Administrator, in
its sole discretion, elects to process a given change in payroll deduction rate more quickly). 
 (e) Notwithstanding the foregoing, to the
extent necessary to comply with Section 423(b)(8) of the Code and Section 3(b), a participant’s payroll deductions may be decreased to zero percent (0%) at any time during an Offering Period. Payroll deductions shall recommence at the
rate originally elected by the participant effective as of the beginning of the first Offering Period which is scheduled to end in the following calendar year, unless terminated by the participant as provided in Section 10. 
 (f) At the time the option is exercised, in whole or in part, or at the time some or all of the Company’s Common Stock issued under the Plan is
disposed of, the participant must make adequate provision for the Company’s federal, state, or other tax withholding obligations, if any, which arise upon the exercise of the option or the disposition of the Common Stock. At any time, the
Company may, but shall not be obligated to, withhold from the participant’s compensation the amount necessary for the Company to meet applicable withholding obligations, including any withholding required to make available to the Company any
tax deductions or benefits attributable to the sale or early disposition of Common Stock by the Employee. 
 7. Grant of Option. On
the Enrollment Date of each Offering Period, each Employee participating in such Offering Period shall be granted an option to purchase on the Exercise Date of such Offering Period (at the applicable Purchase Price) up to a number of shares of
Common Stock determined by dividing such participant’s payroll deductions accumulated prior to such Exercise Date and retained in the participant’s account as of the Exercise Date by the applicable Purchase Price; provided that in no event
shall a participant be permitted to purchase during each Offering Period more than 2,500 shares of Common Stock (subject to any adjustment pursuant to Section 19), and provided further that such purchase shall be subject to the limitations set
forth in Sections 3(b) and 13. The Employee may accept the grant of such option by electing to participate in the Plan in accordance with the requirements of Section 5. The Administrator may, for future Offering Periods, increase or decrease,
in its absolute discretion, the maximum number of shares of Common Stock that a participant may purchase during each Offering Period. Exercise of the option shall occur as provided in Section 8, unless the participant has withdrawn pursuant to
Section 10. The option shall expire on the last day of the Offering Period. 
  

 -5- 

 8. Exercise of Option. 
 (a) Unless a participant withdraws from the Plan as provided in Section 10, his or her option for the purchase of shares of Common Stock shall be
exercised automatically on the Exercise Date, and the maximum number of full shares subject to option shall be purchased for such participant at the applicable Purchase Price with the accumulated payroll deductions in his or her account. No
fractional shares of Common Stock shall be purchased; any payroll deductions accumulated in a participant’s account which are not sufficient to purchase a full share shall be retained in the participant’s account for the subsequent
Offering Period, subject to earlier withdrawal by the participant as provided in Section 10. Any other monies left over in a participant’s account after the Exercise Date shall be returned to the participant. During a participant’s
lifetime, a participant’s option to purchase shares hereunder is exercisable only by him or her. 
 (b) Notwithstanding any contrary
Plan provision, if the Administrator determines that, on a given Exercise Date, the number of shares of Common Stock with respect to which options are to be exercised may exceed (i) the number of shares of Common Stock that were available for
sale under the Plan on the Enrollment Date of the applicable Offering Period, or (ii) the number of shares of Common Stock available for sale under the Plan on such Exercise Date, the Administrator may in its sole discretion (x) provide
that the Company shall make a pro rata allocation of the shares of Common Stock available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as shall be practicable and as it shall determine in its sole
discretion to be equitable among all participants exercising options to purchase Common Stock on such Exercise Date, and continue all Offering Periods then in effect, or (y) provide that the Company shall make a pro rata allocation of the
shares of Common Stock available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as shall be practicable and as it shall determine in its sole discretion to be equitable among all participants exercising
options to purchase Common Stock on such Exercise Date, and terminate any or all Offering Periods then in effect pursuant to Section 20. The Company may make pro rata allocation of the shares of Common Stock available on the Enrollment Date of
any applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional shares of Common Stock for issuance under the Plan by the Company’s shareholders subsequent to such Enrollment Date. 

9. Delivery. As soon as administratively practicable after each Exercise Date on which a purchase of shares of Common Stock occurs, the Company
shall arrange the delivery to each participant, as appropriate, the shares purchased upon exercise of his or her option in a form determined by the Administrator (in its sole discretion) and pursuant to rules established by the Administrator. No
participant shall have any voting, dividend, or other shareholder rights with respect to shares of Common Stock subject to any option granted under the Plan until such shares have been purchased and delivered to the participant as provided in this
Section 9. 
 10. Withdrawal. 
 (a) Under procedures established by the Administrator, a participant may withdraw all but not less than all the payroll deductions credited to his or her account and not yet used to exercise his or her option under
the Plan at any time by (i) submitting to the Company’s payroll office (or its designee) a written notice of withdrawal in the form prescribed by the 

  

 -6- 

 
Administrator for such purpose, or (ii) following an electronic or other withdrawal procedure prescribed by the Administrator. All of the
participant’s payroll deductions credited to his or her account shall be paid to such participant as promptly as practicable after the effective date of his or her withdrawal and such participant’s option for the Offering Period shall be
automatically terminated, and no further payroll deductions for the purchase of shares shall be made for such Offering Period. If a participant withdraws from an Offering Period, payroll deductions shall not resume at the beginning of the succeeding
Offering Period unless the participant re-enrolls in the Plan in accordance with the provisions of Section 5. 
 (b) A
participant’s withdrawal from an Offering Period shall not have any effect upon his or her eligibility to participate in any similar plan which may hereafter be adopted by the Company or in succeeding Offering Periods which commence after the
termination of the Offering Period from which the participant withdraws. 
 11. Termination of Employment. Upon a participant’s
ceasing to be an Employee, for any reason, he or she shall be deemed to have elected to withdraw from the Plan and the payroll deductions credited to such participant’s account during the Offering Period but not yet used to purchase shares of
Common Stock under the Plan shall be returned to such participant or, in the case of his or her death, to the person or persons entitled thereto under Section 15, and such participant’s option shall be automatically terminated. The
preceding sentence notwithstanding, a participant who receives payment in lieu of notice of termination of employment shall be treated as continuing to be an Employee for the participant’s customary number of hours per week of employment during
the period in which the participant is subject to such payment in lieu of notice. 
 12. Interest. No interest shall accrue on the
payroll deductions of a participant in the Plan. 
 13. Stock. 
 (a) Subject to adjustment upon changes in capitalization of the Company as provided in Section 19, the maximum number of shares of Common Stock which
shall be made available for sale under the Plan shall be 200,000 shares of Common Stock plus an annual increase to be added on the first day of the Company’s fiscal year beginning in fiscal year 2005, equal to the lesser of (i) 600,000
shares of Common Stock, (ii) 2% of the outstanding shares of Common Stock on such date or (iii) an amount determined by the Board. 
 (b) Shares of Common Stock to be delivered to a participant under the Plan shall be registered in the name of the participant or in the name of the participant and his or her spouse. 
 14. Administration. The Board or a committee of members of the Board who shall be appointed from time to time by, and shall serve at the pleasure
of, the Board, shall administer the Plan. The Administrator shall have full and exclusive discretionary authority to construe, interpret and apply the terms of the Plan, to determine eligibility, to adjudicate all disputed claims filed under the
Plan and to establish such procedures that it deems necessary for administration of the Plan (including, without limitation, to adopt such procedures and sub-plans as are necessary or appropriate to permit the participation in the Plan by employees
who are foreign nationals or employed outside the United States). The Administrator, in its sole discretion and on such terms and 

  

 -7- 

 
conditions as it may provide, may delegate to one or more individuals all or any part of its authority and powers under the Plan. Every finding, decision and
determination made by the Administrator (or its designee) shall, to the full extent permitted by law, be final and binding upon all parties. 
 15. Designation of Beneficiary. 
 (a) A participant may designate a beneficiary who is to receive any shares of Common Stock
and cash, if any, from the participant’s account under the Plan in the event of such participant’s death subsequent to an Exercise Date on which the option is exercised but prior to delivery to such participant of such shares and cash. In
addition, a participant may designate a beneficiary who is to receive any cash from the participant’s account under the Plan in the event of such participant’s death prior to exercise of the option. If a participant is married and the
designated beneficiary is not the spouse, spousal consent shall be required for such designation to be effective. 
 (b) Such designation of
beneficiary may be changed by the participant at any time. In the event of the death of a participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such participant’s death, the Company shall
deliver such shares and/or cash to the executor or administrator of the estate of the participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares
and/or cash to the spouse or to any one or more dependents or relatives of the participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate. 
 (c) All beneficiary designations under this Section 15 shall be made in such form and manner as the Administrator may prescribe from time to time.

 16. Transferability. Neither payroll deductions credited to a participant’s account nor any rights with regard to the exercise
of an option or to receive shares of Common Stock under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as provided in Section 15) by the
participant. Any such attempt at assignment, transfer, pledge or other disposition shall be without effect, except that the Company may treat such act as an election to withdraw from an Offering Period in accordance with Section 10. 

17. Use of Funds. All payroll deductions received or held by the Company under the Plan may be used by the Company for any corporate purpose,
and the Company shall not be obligated to segregate such payroll deductions. Until shares of Common Stock are issued under the Plan (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the
Company), a participant shall only have the rights of an unsecured creditor with respect to such shares. 
 18. Reports. Individual
accounts shall be maintained for each participant in the Plan. Statements of account shall be given to participating Employees at least annually, which statements shall set forth the amounts of payroll deductions, the Purchase Price, the number of
shares of Common Stock purchased and the remaining cash balance, if any. 
  

 -8- 

 19. Adjustments, Dissolution, Liquidation or Change of Control. 
 (a) Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Common Stock, other securities, or other
property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Common Stock or other securities of the Company, or other change in the corporate
structure of the Company affecting the Common Stock such that an adjustment is determined by the Administrator (in its sole discretion) to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to
be made available under the Plan, then the Administrator shall, in such manner as it may deem equitable, adjust the number and class of Common Stock which may be delivered under the Plan, the Purchase Price per share and the number of shares of
Common Stock covered by each option under the Plan which has not yet been exercised, and the numerical limits of Sections 7 and 13. 
 (b)
Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Offering Period then in progress shall be shortened by setting a new Exercise Date (the “New Exercise Date”), and shall
terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the Board. The New Exercise Date shall be before the date of the Company’s proposed dissolution or liquidation. The Board
shall notify each participant in writing, at least ten (10) business days prior to the New Exercise Date, that the Exercise Date for the participant’s option has been changed to the New Exercise Date and that the participant’s option
shall be exercised automatically on the New Exercise Date, unless prior to such date the participant has withdrawn from the Offering Period as provided in Section 10. 
 (c) Change of Control. In the event of a Change of Control, each outstanding option shall be assumed or an equivalent option substituted by the successor corporation or a Parent or Subsidiary of the successor
corporation. In the event that the successor corporation refuses to assume or substitute for the option, any Offering Periods then in progress shall be shortened by setting a new Exercise Date (the “New Exercise Date”) and shall end on the
New Exercise Date. The New Exercise Date shall be before the date of the Company’s proposed Change of Control. The Board shall notify each participant in writing, at least ten (10) business days prior to the New Exercise Date, that the
Exercise Date for the participant’s option has been changed to the New Exercise Date and that the participant’s option shall be exercised automatically on the New Exercise Date, unless prior to such date the participant has withdrawn from
the Offering Period as provided in Section 10. 
 20. Amendment or Termination. 
 (a) The Administrator may at any time and for any reason terminate or amend the Plan. Except as provided in Section 19, no such termination can
affect options previously granted under the Plan, provided that an Offering Period may be terminated by the Administrator on any Exercise Date if the Administrator determines that the termination or suspension of the Plan is in the best interests of
the Company and its stockholders. Except as provided in Section 19 and this Section 20, no amendment may make any change in any option theretofore granted which adversely affects the rights of any participant. To the extent necessary to
comply with Section 423 of the Code (or any successor rule or provision or any other applicable law, regulation or stock exchange rule), the Company shall obtain stockholder approval in such a manner and to such a degree as required.

  

 -9- 

 (b) Without stockholder consent and without regard to whether any participant rights may be considered to
have been “adversely affected,” the Administrator shall be entitled to change the Offering Periods, limit the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to
amounts withheld in a currency other than U.S. dollars, permit payroll withholding in excess of the amount designated by a participant in order to adjust for delays or mistakes in the Company’s processing of properly completed withholding
elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock for each participant properly correspond with amounts withheld from the
participant’s Compensation, and establish such other limitations or procedures as the Administrator determines in its sole discretion advisable which are consistent with the Plan. 
 (c) In the event the Administrator determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the
Board may, in its discretion and, to the extent necessary or desirable, modify or amend the Plan to reduce or eliminate such accounting consequence including, but not limited to: 
 (i) altering the Purchase Price for any Offering Period including an Offering Period underway at the time of the change in Purchase Price; 

(ii) shortening any Offering Period so that Offering Period ends on a new Exercise Date, including an Offering Period underway at the time of the
Board action; and 
 (iii) allocating shares. 
 Such modifications or amendments shall not require stockholder approval or the consent of any Plan participants. 
 21.
Notices. All notices or other communications by a participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received in the form specified by the Company at the location, or by the person,
designated by the Company for the receipt thereof. 
 22. Conditions Upon Issuance of Shares. Shares of Common Stock shall not be
issued with respect to an option under the Plan unless the exercise of such option and the issuance and delivery of such shares pursuant thereto shall comply with all applicable provisions of law, domestic or foreign, including, without limitation,
the Securities Act of 1933, as amended, including the rules and regulations promulgated thereunder, the Exchange Act and the requirements of any stock exchange upon which the shares may then be listed, and shall be further subject to the approval of
counsel for the Company with respect to such compliance. 
 As a condition to the exercise of an option, the Company may require the person
exercising such option to represent and warrant at the time of any such exercise that the shares are being purchased only for investment and without any present intention to sell or distribute such shares if, in the opinion of counsel for the
Company, such a representation is required by any of the aforementioned applicable provisions of law. 
  

 -10- 

 23. Term of Plan. The Plan shall become effective upon the earlier to occur of its adoption by the
Board or its approval by the stockholders of the Company. It shall continue in effect for a term of twenty (20) years, unless sooner terminated under Section 20. 
 24. Automatic Transfer to Low Price Offering Period. To the extent permitted by any applicable laws, regulations, or stock exchange rules if the
Fair Market Value of the Common Stock on any Exercise Date in an Offering Period is lower than the Fair Market Value of the Common Stock on the Enrollment Date of such Offering Period, then all participants in such Offering Period shall be
automatically withdrawn from such Offering Period immediately after the exercise of their option on such Exercise Date and automatically re-enrolled in the immediately following Offering Period.

	6.	 I understand that if I dispose of any shares received by me pursuant to the Plan within 2 years after the Offering Date (the first day of the Offering Period during

 ARTICLE 10 
 CONFIDENTIALITY 
 Section 10.1. Confidentiality. Each Party (the “Receiving Party”) shall maintain in confidence all Confidential Information
of the other Party (each a “Disclosing Party”) (i) for a period of fifteen (15) years after the date of disclosure for information received in the course of performance under this Agreement, (ii) for a period of
fifteen (15) years after the date of disclosure for information already in the possession of such Party, but in each case, not to exceed five (5) years after termination of this Agreement. Subject to Section 10.2, Marathon shall not
disclose such Confidential Information to any third party except (i) banks, lenders or their representatives, project partners or potential project partners, governmental or quasi-governmental authorities, and national oil companies under
conditions of written confidentiality consistent with the confidentiality terms of this Agreement, (ii) to those of its Personnel and Development Partners who reasonably require such Confidential Information in connection with such Party’s
activities as contemplated by this Agreement. In maintaining the confidentiality of Confidential Information of the other Party, the Receiving Party shall exercise the same degree 

  

 12 

 
of care that it exercises with its own confidential information, and in no event less than a reasonable degree of care. Each Party shall ensure that each of
its Personnel and Development Partners holds in confidence and makes no use of the Confidential Information of the other Party for any purpose other than those permitted under this Agreement or otherwise required by law. Notwithstanding anything to
the contrary herein, each sublicensee of Marathon under Section 3.4 shall be bound by the confidentiality provisions hereof (i) for a period of fifteen (15) years after the date of disclosure by the disclosing Party for information
received in the course of performance under this Agreement, (ii) for a period of fifteen (15) years after the date of disclosure by the disclosing Party for information already in the possession of the other Party Syntroleum acknowledges
that the mere fact that Marathon Personnel are in the possession of Confidential Information and are working with a third party shall be insufficient to prove a breach of confidentiality. Proof of a breach shall require proof of an actual improper
disclosure. 
 Section 10.2. Disclosure to Development Partners. Notwithstanding the foregoing, Marathon shall not disclose
Listed Confidential Information to any Competitors of Syntroleum. 
 Section 10.3. Exceptions to Confidentiality. The obligation
of confidentiality contained in this Agreement shall not apply to the extent that (i) the Receiving Party is required to disclose information by order or regulation of a governmental agency, stock exchange, or a court of competent jurisdiction;
provided, however, that (a) the Receiving Party shall promptly notify the disclosing Party of such order or regulation (when legally permissible) and shall not make any such disclosure without first notifying the Disclosing Party and allowing
the Disclosing Party a reasonable opportunity to seek injunctive relief from (or a protective order with respect to) the obligation to make such disclosure, and (b) such disclosure shall not affect the confidential nature of the information
unless and until an exception in (ii) below applies; or (ii) the Receiving Party can demonstrate that (a) the disclosed information was at the time of such disclosure to the Receiving Party already in (or thereafter enters) the public
domain other than as a result of a breach of an obligation of confidentiality to the Disclosing Party; (b) the disclosed information was rightfully known to the Receiving Party prior to the date of disclosure to the Receiving Party;
(c) the disclosed information was received by the Receiving Party on an unrestricted basis from a source unrelated to the Disclosing Party and not under a duty of confidentiality to the Disclosing Party; or (d) the disclosed information
was independently developed by the Receiving Party without the benefit of any Confidential Information of the Disclosing Party. Specific aspects or details of Confidential Information shall not be deemed to be within the public domain or possession
of the Receiving Party merely because the Confidential Information is embraced by general disclosures in the public domain or possession of the Receiving Party. In addition, any combination of Confidential Information shall not be considered in the
public domain or possession of the Receiving Party merely because individual elements thereof are in the public domain or possession of the Receiving Party unless the combination and its principles are in the public domain or possession of the
Receiving Party.
