Employee shall be entitled to twenty (20) days paid vacation for each full year of employment. ARTICLE II. DUTIES, NON-COMPETITION and NON-SOLICITATION 1. Employee agrees to serve in the position of Chief Executive officer, or such other position as the parties may hereafter agree during the term of this agreement, and to perform diligently and to the best of Employee's abilities the duties and services appertaining to such offices, as well as such additional duties and services appropriate to such office upon which the parties mutually may agree from time-to-time or as shall be designated by the Board of Directors. The Employee also agrees that his employment is subject to the current and future policies and procedures maintained and established by the Employer. The Employee shall devote the Employee's full productive time, best efforts, ability and attention to the business of the Employer and the performance of the Employee's duties. 2. Employee acknowledges and understands that from time to time the Employee's duties may require the Employee to work on-site at a non-company location. In such instance, the Employee agrees to comply with all of the policies, procedures and directives relevant to working at such non-company location. 3. Employee represents and admits that in the termination of the Employee's employment for any reason whatsoever, the Employee's experiences and capabilities are such that the Employee can obtain employment in business engaged in other lines and/or of a different nature, and that the enforcement of a remedy by way of injunction will not prevent the Employee from earning a livelihood. 4. Employee acknowledges that the Employee will receive special knowledge and specialized training from the Employer, included in which is the CONFIDENTIAL INFORMATION identified in Article III below. The Employee further acknowledges that training provided by the Employer and the CONFIDENTIAL INFORMATION is valuable to the Employer and, therefore, the Employer's investment in the training and the protection and 3 maintenance of the CONFIDENTIAL INFORMATION constitutes a legitimate interest to be protected by the Employer by the covenant not to compete, set forth in Article II of this Agreement. 5. Non-Competition. The Employee therefore agrees that for a period of one (1) year after the Employee shall cease to be employed by the Employer for any reason, the Employee shall not engage in any form of business which is competition with the Employer, including through the business of any person, company, firm, corporation, partnership, association, agency, or business, and particularly through a party known to the Employee to be an independent contract sales associate and/or customer of the Employer or with whom the Employee had contact during, or by reason of, the Employee's employment by the Employer. 6. Non-Solicitation. The Employee further agrees that for a period of one (1) year after the Employee shall cease to be employed by the Employer for any reason, the Employee will not, either directly or indirectly, through any person, firm, association or corporation with which the Employee, customer and/or independent contractor sales associate ("Subject Person") is now or may hereafter become associated with, solicit, cause, influence or induce any present or future Subject Person of the Employer or its affiliates to leave the employ or business relationship with the Employer or its affiliates to accept employment or a business relationship with the Employee or with such person, firm, association, or corporation with whom the Employee may then be affiliated. As set forth above, the Employee acknowledges that the foregoing non- competition and non-solicitation covenants are ancillary to or a part of an otherwise enforceable agreement, such being the general agreement of Employment and its related agreements concerning confidentiality and non-disclosure of CONFIDENTIAL INFORMATION and non-solicitation, at the time that this non- competition covenant is made, that the limitations as to time defined herein are reasonable and do not impose a greater restraint than is necessary to protect the goodwill or other business interests of the Employer, that the limitations as to geographic area defined herein are reasonable and do not impose a greater restraint than is necessary to protect the goodwill or other business interests of the Employer, and that the scope of activity to be restrained defined herein is reasonable and does not impose a greater restraint than is necessary to protect the good will or other business interests. 7. Employee agrees that in the highly competitive business in which the Employer is engaged, personal contact is of primary importance in securing new and retaining present Associates and customers. The Employee also agrees that the Employer has a legitimate interest in maintaining its relationships with its Associates and customers and that it would be unfair for the Employee to solicit the business of the Employer's Associates and customers and exploit the personal relationships the Employee develops with the Employer's Associates and customers by virtue of the Employee's access to the Employer's customers as a result of the Employee's employment by the Employer. 4 8. The foregoing covenants not to compete and solicit shall not be held invalid or unenforceable because of the scope or the territory or actions subject thereto or restricted thereby, or the period of time within which such Agreement is operative; but an award or decree in arbitration or any judgment of a court of competent jurisdiction, as the case may be, may define the maximum territory and actions subject thereto and restricted by this Article II and the period of time during which the Agreement is enforceable. Any alleged breach of other provisions of this Agreement asserted by the Employee shall not be a defense for the Employee to claims arising from the Employer's enforcement of the provisions of this paragraph. Should the Employee violate the non- competition, non-solicitation covenants of this Article II, then the period of time for these covenants shall automatically be extended for the period of time from which the Employee began such violation until the Employee permanently ceases such violation. 9. Irrespective of the term of employment under this Agreement, and in consideration of the promises specified in Article II of this Agreement, the Employer agrees as follows: a. To provide specialized training as specified herein; and b. To provide the Employee with access to the Employer's software and files, records, marketing procedures, processes, computer programs, compilations of information, records, Associate and client requirements, pricing techniques, lists, formulae, lists identifying Associates, partners, potential investors, methods of doing business and other CONFIDENTIAL INFORMATION which is regularly used in the operation of the business of the Employer. 10. Employee represents and warrants that the delivery and execution of this agreement will not cause a breach in the terms of any existing agreement to which he is a party nor interfere with any undertakings which he is bound to perform or refrain from under any such agreements. 11. Employee shall be bound by and abide by all employee and officer policies of the Company in effect during the term of his employment. 12. Employee acknowledges and agrees that he owes a fiduciary duty of loyalty, fidelity, and allegiance to act at all times in the best interests of Company. In keeping with these duties, Employee shall make full disclosure to Company of all business opportunities pertaining to Company's business and shall not appropriate for Employee's own benefit business opportunities concerning the subject matter of the fiduciary relationship. 13. Article II, Paragraphs 5 and 6 shall survive the execution, performance and/or termination of this Agreement, subject to the time and scope limitations set forth therein. 5 ARTICLE III.

During the course of the Employee's employment and training incident thereto the Employee will be or was given access to the Employer's CONFIDENTIAL INFORMATION concerning Products and the business operations of the Employer. 3.

The Employee recognizes that the Employee's position with the Employer is one of the highest trust and confidence by reason of the Employee's access to the CONFIDENTIAL INFORMATION and the Employee agrees to use the Employee's best efforts and will exercise utmost diligence to protect and safeguard the CONFIDENTIAL INFORMATION. In this respect, the Employee agrees that fulfilling the obligations of the Agreement is part of the Employee's job responsibilities with the Employer for which the Employee has been retained as an Employee and for which the Employee has received consideration therefor. 6.

The Employee agrees that, during the term of the Employee's employment with the Employer or upon termination thereof, and if requested by the Employer to do so, the Employee will sign an appropriate list of any and all CONFIDENTIAL INFORMATION of the Employer of which the Employee has knowledge or about which the Employee has acquired information. 9.
