As used herein, “Invention” means any discovery, improvement, innovation, idea, formula, or shop right (whether or not patentable, whether or not put into writing and whether or not put into practice) made, generated or conceived by Employee (whether alone or with others) while employed by the Company. For purposes of this Agreement, any discovery, improvement, innovation, idea, formula, or shop right (whether or not patentable, whether or not put into writing and whether or not put into practice) relating directly or indirectly to the business of the Company or to the Company’s actual or demonstrably anticipated business, research or development with respect to which Employee files a patent application within two years after termination of employment with the Company shall be presumed to be an Invention. As used herein, “Work of Authorship” means any original work of authorship within the purview of the copyright laws of the United States of America, and both the Company and Employee intend and agree that all Works of Authorship created by Employee in the course of his employment with the Company will be and shall constitute works made for hire within the meaning and purview of such copyright laws.

(b) Employee will execute and assign any and all applications, assignments, and other documents and will render all assistance which may be reasonably necessary for the Company to obtain patent, copyright, or any other form of intellectual property protection with respect to all Inventions and Works of Authorship in all countries and will cooperate with Syntroleum as reasonably necessary to enforce any such intellectual property protection.

9. Limited Covenants Against Competition; Non-Solicitation.

(a) Employee acknowledges that the services he is to render to the Company are of a special and unusual character with a unique value to the Company, the loss of which cannot adequately be compensated by damages in an action at law. In view of the unique value to the Company of the services of Employee and because of the confidential Trade Secret Information to be obtained by or disclosed to Employee, as set forth above, and as a material inducement to the Company to enter into this Agreement and to pay to Employee the compensation stated in Paragraph 2, Employee covenants and agrees that during the period of Employee’s employment within the Company and for a period of two years following termination of Employee’s employment with the Company for any reason, voluntarily or involuntarily, Employee will not directly or indirectly: (i) start or participate or assist (as a proprietor, partner, shareholder, lender, investor, director, employee, consultant, independent contractor or otherwise) in starting any Competing Business; (ii) assist (as a proprietor, partner, shareholder (except as a holder of 1% or less of the outstanding voting securities or income interest), lender, investor (except as a holder of 1% or less of the outstanding voting securities or income interest), director, employee, consultant, independent contractor or otherwise) any existing Competing Business in the design, development or manufacture of any Competing Product; (iii) sell or assist in the sale of any Competing Product to any person or organization with whom Employee had any contact while employed with the Company; (iv) directly or indirectly solicit for employment or employ any of the Company’s employees; or (v) become employed by a former employee of the Company. Because Syntroleum actively pursues opportunities throughout the world and is engaged in a world-wide oriented business the Employee acknowledges the reasonableness of having no geographic limitation hereunder.

(b) Employee further acknowledges that, while employed by the Company, he will have contact with and become aware of the Company’s customers and licensees and their respective representatives, including their names and addresses, specific needs and requirements, as well as leads and references to prospective customers and licensees. Employee further acknowledges that loss of such customers or licensees would cause the Company great and irreparable harm. Employee agrees that for a period of two years following termination of Employee’s employment with the Company for any reason, voluntarily or involuntarily, Employee will not directly or indirectly solicit, contact, call upon, communicate with or attempt to communicate with any customer or licensee, former customer or licensee, or prospective customer or licensee of the Company for the purpose of selling, installing, implementing, or modifying any Competing Product. This restriction shall apply only to any customer or licensee, former customer or licensee, or prospective customer or licensee of the Company with whom Employee had contact during the last two years of Employee’s employment with the Company.

(c) The Employee agrees that for as long as he is employed by the Company and for a period of two years after termination of Employee’s employment with the Company for any reason, voluntarily or involuntarily, Employee will not solicit, recruit, hire or attempt to solicit, recruit or hire, directly or by assisting others, any other employee of the Company.

(d) As used in this Agreement, (i) “Competing Business” means any person, entity or organization other than the Company which is engaged in or is about to become engaged in the design, manufacture or sale of a Competing Product, (ii) “Competing Product” means any product (including, without limitation, any chemical formula or process) which is or may be marketed in competition with any product marketed or under development by the Company at any time, and (iii) “contact” means interaction between Employee and a customer or licensee, former customer or licensee, or prospective customer or licensee of the Company, which takes place to further any business relationship; or performing services for the customer or licensee, former customer or licensee, or prospective customer or licensee on behalf of the Company.

10. Reasonableness of Restrictions.

(a) Employee expressly acknowledges that he has carefully read and considered the provisions of Paragraphs 6, 7, 8 and 9, and, having done so, agrees that the restrictions set forth in these Paragraphs, including, but not limited to, the time periods and geographic areas of restriction are fair and reasonable and are reasonably required for the protection of the interests of the Company and its officers, directors, shareholders and other employees.

(b) In the event that, notwithstanding the foregoing, any of the provisions of Xxxxxxxxxx 0, 0, 0 xxx 0 xxxxx xx held to be invalid or unenforceable, the remaining provisions thereof shall nevertheless continue to be valid and enforceable as though the invalid or unenforceable parts had not been included therein. In the event that any provision of Paragraphs 6, 7, 8 and 9 relating to the time period and/or the areas of restriction and/or related aspects shall be declared by a court of competent jurisdiction to exceed the maximum restrictiveness such court deems reasonable and enforceable, the time period and/or areas of restriction and/or related aspects deemed reasonable and enforceable by the court shall become and thereafter be the maximum restriction in such regard, and the restriction shall remain enforceable to the fullest extent deemed reasonable by such court.

11. Requests for Clarification. In the event Employee is uncertain as to the meaning of any provision of this Agreement or its application to any particular information, item or activity, Employee will inquire in writing to the Company, specifying any areas of uncertainty. The Company will respond in writing within a reasonable time and will endeavor to clarify any areas of uncertainty, including such things as whether it considers particular information to be its Trade Secret Information or whether it considers any particular activity or employment to be in violation of this Agreement.

12. Remedies. In the event of a breach or threatened breach of any of the covenants in Paragraphs 6, 7, 8 and 9, the Company shall have the right to seek monetary damages and equitable relief, including specific performance by means of an injunction against Employee or against Employee’s partners, agents, representatives, servants, employers, employees, family members and/or any and all persons acting directly or indirectly by or with him, to prevent or restrain any such breach.

13. Term and Termination.

(a) The term of this Agreement shall be for an initial term of 12 months from the effective date hereof, unless sooner terminated as provided herein, and shall thereafter be automatically renewed for successive terms of 12 months each unless sooner terminated as provided herein.

(b) Employment of Employee under this Agreement may be terminated:

(i) by the Company upon the death of Employee.

(ii) by the Company if Employee becomes disabled. For the purposes of this Agreement, Employee will be deemed disabled if he (i) has been declared legally incompetent by a final court decree (the date of such decree being deemed to be the date on which the disability occurred), or (ii) receives disability insurance benefits from any disability income insurance policy maintained by the Company for a period of three consecutive months, or (iii) has been found to be disabled pursuant to a disability determination. A “disability determination” means a finding that Employee, because of a medically determinable disease, injury, or other mental or physical disability, is unable to perform substantially all of his regular duties to the Company and that such

Syntroleum Employment Agreement

CONFIDENTIAL

disability is determined or reasonably expected to last at least six months. The disability determination shall be based upon the written opinion of the physician regularly attending Employee whose disability is in question. If the Company disagrees with the opinion of this physician (the “First Physician”), it may engage, at its own expense, another physician of its choice (the “Second Physician”) to examine Employee. If the First and Second Physicians agree in writing that Employee is or is not disabled, their written opinion shall, except as otherwise set forth in this subsection, be conclusive on the issue of disability. If the First and Second Physicians disagree on the disability of Employee, they shall choose a third consulting physician (whose expense shall be borne by the Company), and the written opinion of a majority of these three physicians shall, except as otherwise provided in this subsection, be conclusive as to Employee’s disability. The date of any written opinion conclusively finding Employee to be disabled is the date on which the disability will be deemed to have occurred. If there is a conclusive finding that Employee is not totally disabled, the Company shall have the right to request additional disability determinations provided it agrees to pay all the expenses of the disability determinations and does not request an additional disability determination more frequently than once every three months. In connection with any disability determination, Employee hereby consents to any required medical examination, and agrees to furnish any medical information requested by any examining physician and to waive any applicable physician-patient privilege that may arise because of such examination. All physicians except the First Physician must be board-certified in the specialty most closely related to the nature of the disability alleged to exist.

(iii) by the Company when Employee reaches mandatory retirement age under any retirement policy applicable to all executive officers adopted by the Company.

(iv) by mutual agreement of Employee and the Company.

(v) by the Company upon the dissolution and liquidation of the Company (other than as part of a reorganization, merger, consolidation or sale of all or substantially all of the assets of the Company whereby the business of the Company is continued).

(vi) by the Company for just cause at any time upon written notice. For purposes of this Agreement, “just cause” shall mean any one or more of the following: (A) Employee’s material breach of his obligations, duties and responsibilities under any term or provision of this Agreement, which breach remains uncured for a period of five days after written notice by the Company to Employee; (B) Employee’s failure to adhere to the reasonable standards of performance prescribed by the Company; (C) Employee’s act of insubordination to the Company’s Board of Directors; (D) Employee’s gross negligence or willful misconduct in the performance of his duties under this Agreement; (E) Employee’s dishonesty, fraud, misappropriation or embezzlement in the course of, related to or connected with the business of the Company; (F) Employee’s conviction of a felony; or (G) Employee’s failure (after written notice to Employee of such failure and Employee not correcting such failure within five days of such notice) to devote his time, attention and best efforts to the business of the Company as provided in this Agreement.

(vii) by either the Company or Employee upon 60 days written notice.

(c) Any termination of Employee’s employment, either by the Company or Employee, shall be communicated by a written notice of termination to the other party.

(d) If Employee’s employment is terminated pursuant to the terms of this Agreement for any reason, Employee shall be entitled to all arrearages of salary and expenses up to and including the date of termination but shall not be entitled to further compensation. Provided, that if, Employee’s employment is terminated by the Company for any reason other than Employee’s death, disability or retirement, the Company’s dissolution or just cause as provided in Paragraphs 13(b)(i), (ii), (iii), (v) or (vi), respectively, Employee shall be entitled to and the Company shall pay Employee all arrearages of salary and expenses up to and including the date of termination and, in addition, Employee’s monthly base salary for an additional period of 24 months.

(e) Upon expiration of the term of this Agreement or upon earlier termination of this Agreement, Employee shall deliver all Trade Secret Information of the Company to an authorized representative of the Company, and the non-disclosure provisions of Paragraph 6 shall survive such expiration or termination and shall remain in full force and effect for a period of 15 years from such expiration or termination.

14. Change of Control.

(a) In the event of a Change of Control of the Company and (i) during the one-year period immediately following any Change of Control, the Company terminates Employee’s employment for any reason other than Employee’s death, disability, retirement or just cause as provided in Paragraphs 13(b)(i), (ii), (iii) and (vi), respectively, (ii) the Employee terminates his employment for Good Reason, or (iii) during the Window Period the Company or Employee terminates Employee’s employment for any reason, then the Company or its successor shall pay Employee his full base salary in effect at the time of the notice of termination through the date of termination, and in lieu of any further salary payments for periods subsequent to the date of termination, the Company or its successor shall pay Employee as severance pay an amount equal to two times Employee’s full base salary in effect on the date of termination payable in 24 equal monthly installments beginning on the first day of the first calendar month following the date of Employee’s termination and continuing on the first day of each month thereafter until paid.

(b) Anything in this Agreement to the contrary notwithstanding, if a Change of Control occurs and if the Employee’s employment with the Company is terminated prior to the date on which the Change of Control occurs, and if it is reasonably demonstrated by the Employee that such termination of employment (i) was at the request of a third party who has taken steps reasonably calculated to effect the Change of Control or (ii) otherwise arose in connection with or anticipation of the Change of Control, then for all purposes of this Agreement, the “Change of Control” shall be deemed to have occurred on the date immediately prior to the date of such termination of employment.
