C.    Dishonesty, fraud, willful misconduct, unlawful discrimination or theft on the part of Executive (whether within the workplace or elsewhere);

D.    Executive’s using for his own benefit or the benefit of any third party any Confidential Information of Employer (as defined in Section 7.03 (Trade Secrets)), or its respective successors and assigns, or willfully or negligently divulging any such Confidential Information to third parties, without the prior written consent of the CEO or Board of Directors, or any violation by Executive of any of his obligations under Article VII hereof; and

ARTICLE VI

EXPENSE REIMBURSEMENT

Executive is authorized to incur reasonable business expenses in connection with the business of Employer, including expenditures for entertainment and travel. Subject to the requirements of this Article VI, Employer will reimburse Executive from time to time for all reasonable business expenses that are incurred and submitted for reimbursement in compliance with Employer’s policies and procedures.

ARTICLE VII

COVENANT NOT TO COMPETE, TRADE SECRETS, AND ASSIGNMENTS

Covenant Not to Compete

7.01    Executive recognizes and acknowledges that Employer is placing its confidence and trust in Executive. Executive shall have access to information, which enables Employer to be successful in its business. Some of the information may be confidential and constitute trade secrets; that information when combined with all other information regarding Employer constitutes proprietary information, the Executive’s unauthorized use of which could seriously affect the ability of Employer to do business. Executive, therefore, covenants and agrees that for a period beginning on the Effective Date and ending six (6) months after his last date of employment, Executive shall not:

A.    Either directly or indirectly engage in, or assist any person or entity to engage in, any business that is in direct or indirect competition with the Business of the Employer for which Executive performed services during the term hereof. As used in this Article VII, the term “Business of the Employer” shall include all business activities in which the Employer is now engaged, including, but not limited to, the design, manufacture, marketing and distribution by the Employer of various automation control products, and shall further include any other line of business in which the Employer is engaged on the last date of Executive’s employment.

B.    Attempt in any manner to solicit, on his own behalf or on behalf of any person or entity, Business from any Customer of Employer with whom, or with whose account, Executive had direct contact during his employment, or of whom Executive learned during his employment. For the purpose of this provision, “Business” shall mean the provision of products or services of the type that Employer has provided to such customer at any time during or after

5

Executive’s employment with Employer. For purpose of this Agreement, “Customer” shall mean any person or entity that, at any time during the last six (6) months of Executive’s employment, purchased goods or services from Employer, or that Employer actively pursued or specifically planned to pursue for the purpose of selling goods or services.

C.    Either directly or indirectly be or become a shareholder, joint venturer in or owner (in whole or in part) of or be a partner of or associated with or have any proprietary or financial interest in any firm, corporation, joint venture, partnership or association or other entity that is engaged in or is carrying on any business that is in direct or indirect competition with the Business of Employer.

D.    Executive hereby recognizes and acknowledges that the existing business area of Employer extends throughout the United States and therefore agrees that the covenants contained in this Section 7.01 shall be applicable in and throughout such area. Executive further warrants and represents that, because of his varied skill and abilities, he does not need to compete with the Business of Employer in the area described above, in order to make a living. Nothing in this Section will prevent Executive from owning less than five percent (5%) of the stock of any publicly traded corporation during the term hereof or after the termination of his employment as long as Executive is not a participant in the management or affairs of the corporation in a manner that would otherwise violate any prohibition contained in this Section.

Covenant Not to Solicit Employees

7.02    For one year following his last date of employment, Executive shall not either directly or indirectly solicit for employment or employ, either on his own behalf or on behalf or any other person or entity, any person who was employed by Employer at any time during the six (6) months prior to the last date of Executive’s employment with Employer except by general solicitation advertising.

Trade Secrets

7.03    Employer shall provide Executive with Confidential Information regarding Employer’s business. For the purpose of this provision, “Confidential Information” shall mean all information, in any form, owned, possessed or used by Employer, that is not generally available to the public (other than as the result of a breach by any person or entity of a contractual, statutory or common law duty of confidentiality), including but not limited to information pertaining to the financial condition of Employer, its products, processes, properties, assets, inventions, plans, proprietary rights, Customers, markets, technology, know-how, trade secrets, prospects, proposals, concepts and/or other aspects of the Business of Employer. Accordingly, Executive agrees that he will not, during or after the Term of his employment with Employer, disclose to any person or entity or use any such Confidential Information without the express consent of Employer.

Records

7.04    All files of customers and of Employer and all records of the accounts of customers, and any other records, memoranda, etc., relating in any manner whatsoever to Employer’s customers, product, the Business of Employer, the Confidential Information, suppliers or prospective customers or prospective suppliers of Employer, whether prepared by Executive or otherwise coming into his possession, shall be the exclusive property of Employer. All such files and records, both originals and copies, shall be immediately placed in the physical

6

possession of Employer on or before the last date of Executive’s employment with Employer or at any other time specified by the CEO or Board of Directors.

Breach

7.05    Executive hereby recognizes and acknowledges that irreparable injury or damage shall result to the Business of Employer in the event of a breach or threatened breach by Executive of any of the terms or provisions of this Article VII, and Executive therefore agrees that Employer shall be entitled to an injunction restraining Executive from engaging in any activity constituting such breach or threatened breach. Nothing contained herein shall be construed as prohibiting Employer from pursuing any other remedies available to Employer at law or in equity for such breach or threatened breach, including, but not limited to, the recovery of damages from Executive.

Survival

7.06    Notwithstanding the termination of the employment of Executive or the termination of this Agreement, the provisions of this Article VII shall survive and be binding upon Executive unless a written agreement that specifically refers to the termination of the obligations and covenants of this Article VII is executed by Employer.
