1

Executive Incentive Plan (“EIP”). Such investment shall be made by the Company applying not more than $50,000 from the Sign-on-Bonus (as specified in Section 4(b) below). In connection with the foregoing and as a condition to the purchase of such shares, Employee agrees to execute such documents and take such other action as may reasonably be required by Company or the Company’s parent, including, but not limited to, executing a subscription agreement in a form satisfactory to the Company’s parent and executing a counterpart to the Investor Stockholders Agreement, dated as of June 16, 2005, by and between the Company’s parent and the stockholders of the Company’s parent.

Section 4.                                           Compensation. Except as otherwise provided for herein, for all services to be performed by the Employee in any capacity hereunder, including without limitation any services as an officer, director, member of any committee, or any other duties assigned him, throughout the Employment Period the Company shall pay or provide Employee with the following, and Employee shall accept the same, as compensation for the performance of his undertakings and the services to be rendered by him:

(a)                                           Base Salary. Initially, Employee will be entitled to an annual salary of One Hundred Ninety Thousand Dollars ($190,000) (the “Base Salary”), which shall be paid in accordance with the Company’s policies and procedures. The Base Salary may not be reduced for any reason during the first two years of Employee’s employment with the Company unless the salaries of other comparable level executives with the Company are also reduced. Thereafter, the Employee’s base salary may be changed at annual intervals, based on Employee’s and Company’s performance, which may include, without limitation, participation in a period salary evaluation program on the same basis as other employees of the Company of similar position.

(b)                                           Sign on Bonus.

This advance payment shall also be forgiven if Employee is terminated without cause during the first year of this Agreement. Upon termination for cause within the first year of Employee’s employment with the Company, the Company may deduct from Employee’s paycheck(s) or other amounts owed Employee such advance payment (or any other advances previously made to Employee). To the extent that such deductions are insufficient to fully reimburse the Company, Employee shall be liable to the Company for the balance of the advances previously received.

(c)                                            Annual Incentive Compensation. Employee shall be provided target incentive compensation (either in cash, phantom stock, or Common Stock of the Company’s parent, as specified by the administrative committee of the Company’s Short-Term Incentive Plan (“STIP”)) pursuant to the terms and conditions of the STIP.

The first year incentives shall include sixty percent (60%) of Base Salary in cash, stock, or phantom stock

2

(g)                                            Vacation. An amount of paid vacation to which an employee with fifteen (15) years of service with the Company is entitled to receive under the Company’s vacation policy (a minimum of four weeks), and all paid holidays given by the Company to employees in Employee’s position, or similar positions.

Section 5.                                           Restrictions.

(a)                                           Acknowledgements. Employee acknowledges and agrees that: (1) during the term of Employee’s employment, because of the nature of Employee’s responsibilities and the resources provided by the Company, Employee will acquire valuable and confidential skills, information, trade secrets, and relationships with respect to the Company’s business practices

3

and operations; (2) Employee may develop on behalf of the Company a personal acquaintance and/or relationship with various persons, including, but not limited to, customers and suppliers, which acquaintances may constitute the Employee’s only contact with such persons, and, as a consequence of the foregoing, Employee will occupy a position of trust and confidence with respect to the Company’s affairs; (3) the Business involves the marketing and sale of the Company’s products and services to customers throughout the entire world, that the Company’s competitors, both in the United States and internationally, consist of both domestic and international businesses, and the services to be performed by Employee for the Company involve aspects of both the Company’s domestic and international business; (4) it would be impossible or impractical for Employee to perform his duties for the Company without access to the Company’s confidential and proprietary information and contact with persons that are valuable to the goodwill of the Company. Employee acknowledges that if he went to work for or otherwise performs services for a third party engaged in a business substantially similar to the Business, the disclosure by Employee to a third party of such confidential and proprietary information and/or the exploitation of such relationships would be inevitable.

(b)                                           Reasonableness. In view of the foregoing and in consideration of the remuneration to be paid to Employee, Employee agrees that it is reasonable and necessary for the protection of the goodwill and business of the Company that the Employee make the covenants contained in this Agreement regarding the conduct of Employee during and subsequent to Employee’s employment by the Company, and that the Company will suffer irreparable injury if Employee engages in conduct prohibited by this Agreement.

(c)                                            Non-Compete, (i) During the term of Employee’s employment by the Company, (ii) if Employee’s employment is terminated by Employee or by the Company with cause, then for a period of a period of two (2) years after such termination, or (iii) if Employee’s employment is terminated by the Company without cause prior to the expiration of the two (2) years following the Effective Date, then for a period of twelve (12) month after such termination: neither Employee, nor any other person or entity with Employee’s assistance, nor any entity in which Employee direcdy or indirectly has any interest of any kind (without limitation) shall anywhere in the world, directly or indirectly own, manage, operate, control, be employed by, solicit sales for, invest in, participate in, advise, consult with, or be connected with the ownership, management, operation, or control of any business which is engaged, in whole or in part, in the Business, or any business that is competitive therewith or any portion thereof, except for the exclusive benefit of the Company.

(d)                                           No Raiding. In addition, (i) during the term of Employee’s employment by the Company, (ii) if Employee’s employment is terminated by Employee or by the Company with cause, then for a period of a period of two (2) years after such termination, or (iii) if Employee’s employment is terminated by the Company without cause prior to the expiration of the two (2) years following the Effective Date, then for a period of twelve (12) month after such termination: neither the Employee nor any person or entity with his assistance nor any entity which the Employee or any person with his assistance or any person who he directly or indirectly controls shall, directly or indirectly, (1) solicit or take any action to induce any employee to quit or terminate their employment with the Company or the Company’s affiliates, or (2) employ as an

4

employee, independent contractor, consultant, or in any other position, any person who was an employee of the Company or the Company’s affiliates during the aforementioned period.

(e)                                            Confidentiality. Without the express written consent of the Company, Employee shall not at any time (either during or after the termination of the term of Employee’s employment) use (other than for the benefit of the Company) or disclose to any other business entity proprietary or confidential information concerning the Company, the Company’s parent’s, or any of their affiliates, or the Company’s, the Company’s parent, or any of their affiliates’ trade secrets or inventions of which Employee has gained knowledge during his employment with the Company. This paragraph shall not apply to any such information that: (1) Employee is required to disclose by law; (2) has been otherwise disseminated, disclosed, or made available to the public; (3) was obtained after his employment with the Company ended and from some source other than the Company, which source was under no obligation of confidentiality.

(f)                                             Effect of Breach. Employee agrees that a breach of this Section 5 cannot adequately be compensated by money damages and, therefore, the Company shall be entitled, in addition to any other right or remedy available to it (including, but not limited to, an action for damages), to an injunction restraining such breach or a threatened breach and to specific performance of such provisions, and Employee hereby consents to the issuance of such injunction and to the ordering of specific performance, without the requirement of the Company to post a bond or other security.

(g)                                            Other Rights Preserved. Nothing in this Section eliminates or diminishes rights which the Company may have with respect to the subject matter hereof under other agreements, the governing statutes, or under provisions of law, equity, or otherwise. Without limiting the foregoing, this section does not limit any rights the Company may have under any agreement with Employee regarding trade secrets and confidential information.

(a)                                           Without Cause. At any time at the election of either Employee or the Company for any reason or no reason, without cause, but subject to the provisions of this Agreement. It is expressly understood that Employee’s employment is strictly “at will.”

(a)                                           If Employee’s employment is terminated (i) by Employee, or (ii) by the Company for Cause, the Company shall pay Employee’s compensation only through the last day of the Employment Period (less any amounts the Company may off-set or deduct as specified in this Agreement), and, except as may otherwise be expressly provided in this Agreement or in any Benefit Plan, the Company shall have no further obligation to Employee.

(b)                                           If Employee’s employment is terminated by the Company prior to the expiration of two (2) years following the Effective Date for any reason other than Cause and for so long as Employee is not in breach of his continuing obligations under Section 5, the Company shall (i) continue to pay Employee an amount equal to his Base Salary in effect immediately prior to the termination of his employment for a period of twelve (12) months (less any amounts the Company may off-set or deduct as specified in this Agreement), and (ii) pay the costs of COBRA medical and dental benefits coverage which are offered to Employee after termination for a period of twelve (12) months.

(a)                                           No Conflicts. Employee represents and warrants to the Company that Employee is under no duty (whether contractual, fiduciary, or otherwise) that would prevent, restrict, or limit Employee from fully performing all duties and services for the Company, and the performance of such duties and services shall not conflict with any other agreement or obligation to which Employee is bound.

(b)                                           No Hardship. Employee represents and acknowledges that Employee’s experience and/or abilities are such that observance of the covenants contained in this Agreement will not cause Employee any undue hardship nor will they unreasonably interfere with Employee’s ability to earn a livelihood.

(a)                                           Mediation. Employee and the Company agree to submit, prior to arbitration, all unsettled claims, disputes, controversies, and other matters in question between them arising out of or relating to this Agreement (including but not limited to any claim that the Agreement or

6

any of its provisions is invalid, illegal, or otherwise voidable or void) or the dealings or relationship between Employee and the Company (“Disputes”) to mediation in Wichita, Kansas and in accordance with the Commercial Mediation Rules of the American Arbitration Association currently in effect.

The mediator shall be disqualified as a witness, consultant, expert, or counsel for either party with respect to the matters in Dispute and any related matters. The Company and Employee shall pay their respective attorneys’ fee and other costs associated with the mediation, and the Company and Employee shall equally bear the costs and fees of the mediator. If a Dispute cannot be resolved through mediation within ninety (90) days of being submitted to mediation, the parties agree to submit the Dispute to arbitration.

All matters relating to arbitration will be governed by the federal Arbitration Act (9 U.S.C. §§ 1 et. seq.) and not by any state arbitration law. The arbitrator will have the right to award or include in his award any relief which he deems proper under the circumstances, including, without limitation, money damages (with interest on unpaid amounts from the date due), specific performance, injunctive relief, and of this Agreement, reasonable attorneys’ fees and costs, provided that the arbitrator will not have the right to amend or modify the terms of this Agreement. The award and decision of the arbitrator will be conclusive and binding upon all parties hereto, and judgment upon the award may be entered in any court of competent jurisdiction. Except as specified above, the Company and Employee shall pay their respective attorneys’ fee and other costs associated with the arbitration, and the Company and Employee shall equally bear the costs and fees of the arbitrator.

(c)                                            Confidentiality. Employee and the Company agree that they will not disclose, or permit those acting on their behalf to disclose, any aspect of the proceedings under Section 9(a) and Section 9(b), including but not limited to the resolution or the existence or amount of any award, to any person, firm, organization, or entity of any character or nature, unless divulged (i) to an agency of the federal or state government, (ii) pursuant to a court order, (iii) pursuant to a requirement of law, (iv) pursuant to prior written consent of the Company or Employee, or (v) pursuant to a legal proceeding to enforce a settlement agreement or arbitration award. This provision is not intended to prohibit nor does it prohibit Employee’s or the Company’s disclosures of the terms of any settlement or arbitration award to their attorney(s), accountant(s), financial advisor(s), or family members, provided that they comply with the provisions of this paragraph.

(d)                                           Injunctions. Notwithstanding anything to the contrary contained in this Section 9, the Company and Employee shall have the right in a proper case to obtain temporary restraining orders and temporary or preliminary injunctive relief from a court of competent jurisdiction; provided, however, that the Company and Employee must contemporaneously

7

submit the Disputes for non-binding mediation under Section 9(a) and then for arbitration under Section 9(b) on the merits as provided herein if such Disputes cannot be resolved through mediation.

Section 10.                                    General.

This Agreement shall be binding upon and shall inure to the benefit of the Company, its successors and assigns, and Employee and shall be enforceable by them and Employee’s heirs, legatees, legal personal representatives. If Employee dies during the term of this Agreement, the obligation to pay salary and provide benefits shall immediately cease; and, absent actual notice of any probate proceeding, the Company shall pay any compensation due for the period preceding Employee’s death to the following person(s) in order of preference: (i) spouse of Employee; (ii) children of Employee eighteen years of age and over, in equal shares; (iii) father, mother, sisters, and brothers, in equal shares; or (d) the person to whom funeral expenses are due.

No provisions of this Agreement may be modified, waived, or discharged unless such waiver, modification, or discharge is agreed to in a writing signed by Employee and an appropriate officer of the Company empowered to sign the same by the Board of Directors of the Company. No waiver by either party at any time of any breach by the party of, or compliance with, any condition or provision of this Agreement to be performed by the other party shall be deemed a waiver of similar or dissimilar provisions or

8

conditions at the same time or at any prior to subsequent time. The validity, inteipretation, construction, and performance of this Agreement shall be governed by the laws of the State of Kansas; provided, however, that the corporate law of the state of incorporation of the Company’s parent shall govern issues related to the issuance of shares of its Common Stock. Except as provided in Section 9, any action brought to enforce or interpret this Agreement shall be maintained exclusively in the state and federal courts located in Wichita, Kansas.

(d)                                           Interpretation. The headings contained herein are for reference purposes only and shall not in any way affect the meaning or interpretation of any provision of this Agreement. No provision of this Agreement shall be interpreted for or against any party hereto on the basis that such party was the draftsman of such provision; and no presumption or burden of proof shall arise disfavoring or favoring any party by virtue of the authorship of any of the provisions of this Agreement.

(e)                                            Counterparts. The Company and Employee may execute this Agreement in any number of counterparts, each of which shall be deemed to be an original but all of which shall constitute but one instrument. In proving this Agreement, it shall not be necessary to produce or account for more than one such counterpart.

(f)                                             Invalidity of Provisions. If a court of competent jurisdiction shall declare that any provision of this Agreement is invalid, illegal, or unenforceable in any respect, and if the rights and obligations of the Parties to this Agreement will not be materially and adversely affected thereby, in lieu of such illegal, invalid, or unenforceable provision the court may add as a part of this Agreement a legal, valid, and enforceable provision as similar in terms to such illegal, invalid, or unenforceable provision as is possible. If such court cannot so substitute or declines to so substitute for such invalid, illegal, or unenforceable provision, (i) such provision will be fully severable; (ii) this Agreement will be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part hereof; and (iii) the remaining provisions of this Agreement will remain in full force and effect and not be affected by the illegal, invalid, or unenforceable provision or by its severance herefrom. The covenants contained in this Agreement shall each be construed to be a separate agreement independent of any other provision of this Agreement, and the existence of any claim or cause of action of Employee against the Company, predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of any of said covenants.

(g)                                            Entire Agreement. This Agreement (together with the documents expressly referenced herein) constitutes the entire agreement between the parties, supersedes in all respects any prior agreement between the Company and Employee and may not be changed except by a writing duly executed and delivered by the Company and Employee in the same manner as this Agreement.
