ARTICLE 5

TRADE SECRETS AND CONFIDENTIAL INFORMATION

5.01        During the term of Zinn’s employment, the Company will provide Zinn access to, so she may become familiar with, various trade secrets and other confidential or proprietary information of the Company, train her in the use of same, and provide associates a working environment in which she can contribute toward enhancing same and upgrading her general knowledge.  Trade secrets, proprietary information and confidential information encompass, without limitation, anything which is owned by the Company and is regularly used in the operation of the business of the Company to obtain a competitive advantage over the Company’s competitors who do not know, have access to, or utilize such information or trade secrets.  Proprietary information further includes, but is not limited to, records, files, documents, bulletins, publications, manuals, financial data and information concerning and the identity of customers, prospects and suppliers.  Trade secrets further include, but are not limited to, specifications, software programs, both the source code and the object code, documentation, flow charts, diagrams, schematics, data, data bases, and business and production methods and techniques.

Zinn recognizes that if she breaches this agreement and discloses confidential information or trade secrets of the Company or any of its affiliates or subsidiaries, the Company will suffer substantial, irreparable and continuing injuries, damages and costs attendant thereto.  Further, recognizing that money damages may not provide adequate relief, Zinn agrees that, in the event that she breaches or threatens to breach this Agreement, the Company shall be entitled to a preliminary or permanent injunction in order to prevent the continuation of such harm and, as liquidated damages, Zinn shall forfeit all payments made pursuant to this Agreement from the date the Agreement was breached and any payments that are or may be due pursuant to this Agreement, as well as any rights or benefits, including health insurance benefits.

5.03        Zinn and the Company acknowledge and agree that the fact that the Parties have entered into this Agreement and the terms of this Agreement are confidential.  Neither of the Parties may therefore disclose the terms of this Agreement to others, except as necessary with regard to the filing of income taxes and other necessary documents or as required by law, or pursuant to a subpoena or court order, unless such disclosure has been approved by the other Party’s written permission.

ARTICLE 6

NON-COMPETITION AGREEMENT

Zinn agrees that upon her termination of employment from the Company, for a period of two (2) years, she will not engage or participate, directly or indirectly, in competition with the Company or any of its affiliates or subsidiaries without the prior written consent of the Company which consent shall not be unreasonably withheld.  This Agreement shall prohibit Zinn from, among other things, attempts to serve or assist others in serving the Company’s present or potential customers.  Zinn further agrees that she will never at any time after executing this Agreement, assist any person or entity in buying, merging with or acquiring the Company unless the Company consents in writing.

7.03        The Company and Zinn recognize and agree that the damages to the Company for violation of Articles 5,6 and 7 may be difficult, if not impossible to ascertain, and therefore the Parties hereby agree that in the event Zinn breaches these Articles 5, 6, and 7, the Company shall be entitled to liquidated damages for such breach which shall be forfeiture and reimbursement by Zinn of all amounts paid to Zinn from the time of the breach, received by Zinn from Company pursuant to this
