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 4 Exhibit 10.5 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 with whom the Employee had contact during his employment with the Company.

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 Paragraphs 6, 7, 8 and 9 shall be 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. 5 Exhibit 10.5 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. In lieu thereof, or should a court refuse for any reason to grant equitable relief to prevent continuing breaches of the covenants in Paragraphs 6, 7, 8 and 9, the Company shall be entitled to liquidated damages equal to 100% of the gross amount derived by the breaching party from all transactions in breach of the restrictive covenants in this Agreement, it being impossible to ascertain or estimate the entire or exact cost, damage or injury which the Company may sustain by reason of the breach, and such sum is agreed on as compensation for the injury suffered by the Company, and not as a penalty. 13. Term and Termination. (a) The term of this Agreement shall be for an initial term of ____ 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 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 6 Exhibit 10.5 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 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 7 Exhibit 10.5 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, at any time after the first 12 months of this Agreement, Employee's employment is terminated by the Company for any reason other than pursuant to Paragraph 13(b)(v) or (vi), 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 salary for an additional period of ______ months. 14. Resignation Upon Termination. In the event of termination of this Agreement other than for death, Employee agrees to resign from all positions held in the Company, including without limitation any position as a director, officer, agent, trustee or consultant of the Company or any affiliate of the Company. 15. Notice to Subsequent Employers. For a period of two years after termination of Employee's employment with the Company for any reason, Employee will inform any new employer (before accepting employment) of the terms of this Agreement. 16. Obligations Unconditional. The obligations of the parties under this Agreement are unconditional and do not depend upon the performance of any agreements, duties, obligations, or terms outside this Agreement. 17. Waiver. A party's failure to insist on compliance or enforcement of any provision of this Agreement shall not affect the validity or enforceability or constitute a waiver of future enforcement of that provision or of any other provision of this Agreement by that party or any other party. 18. Governing Law. This Agreement shall in all respects be subject to, and governed by, the laws of the State of Oklahoma. 19. Severability. If for any reason any paragraph, term or provision of this Agreement is held to be invalid or unenforceable for any reason, such invalidity or unenforceability shall not affect any other provision hereof, and this Agreement shall be construed and enforced as if such provision had not been included herein and all other valid provisions herein shall remain in full force and effect. If for any reason the restrictions and covenants contained herein are held to cover a geographical area or be for a length of time which is unreasonable or unenforceable, or in any other way are construed to be too broad or to any extent invalid, then to the extent the same are or would be valid or enforceable 8 Exhibit 10.5 under applicable law, any court of competent jurisdiction shall construe and interpret or reform this Agreement to provide for a covenant having the maximum area, time or other provisions (not greater than those contained herein) as shall be valid and enforceable under such applicable law. 20. Jurisdiction. The Company and Employee intend to and hereby confer jurisdiction to enforce the provisions of this Agreement and any restrictive covenants contained herein upon the courts of any jurisdiction within the geographical scope of such covenants. If the courts of any one or more of such jurisdictions hold the provisions of this Agreement or any of the restrictive covenants contained herein unenforceable by reason of the breadth of such scope or otherwise, it is the intention of the Company and Employee that such determination not bar or in any way affect the Company's right to the relief provided herein in the courts of any other jurisdiction within the geographical scope of such covenants, as to breaches of such covenants as they relate to each jurisdiction being, for this purpose, severable into diverse and independent covenants. 21. Notice. Any and all notices required or permitted herein shall be deemed delivered if delivered personally or if mailed by registered or certified mail to the Company at its principal place of business and to Employee at the address hereinafter set forth following Employee's signature, or at such other address or addresses as either party may hereafter designate in writing to the other. 22.
