7. Director Covenants.

(a) Unauthorized Disclosure. The Director agrees and understands that in the Director’s position with the Company, the Director has been and will be exposed to and receive information relating to the confidential affairs of the Company, including, but not limited to, technical information, business and marketing plans, strategies, customer information, other information concerning the Company’s products, promotions, development, financing, expansion plans, business policies and practices, and other forms of information considered by the Company to be confidential and in the nature of trade secrets. The Director agrees that during the Directorship Term and thereafter, the Director will keep such information confidential and will not disclose such information, either directly or indirectly, to any third person or entity without the prior written consent of the Company; provided, however, that (i) the Director shall have no such obligation to the extent such information is or becomes publicly known or generally known in the Company’s industry other than as a result of the Director’s breach of her obligations hereunder and (ii) the Director may, after giving prior notice to the Company to the extent practicable under the circumstances, disclose such information to the extent required by applicable laws or governmental regulations or judicial or regulatory process.

(c) Non-Compete. Subject to the applicable provisions of this Agreement, the Director shall not, so long as he is a member of the Board and for a period of 12 months following termination of this Agreement for whatever reason, directly or indirectly as owner, partner, joint venture, stockholder, employee, broker, agent principal, corporate officer, director, licensor or in any other capacity whatsoever, engage in, become financially interested in, be employed by, or have any connection with any business or venture that is engaged in any activities involving services or products which compete, directly or indirectly, with the services or products provided or proposed to be provided by the Company or its subsidiaries or affiliates; provided, however, that the Director may own securities of any public corporation which is engaged in such business but in an amount not to exceed at any one time, three (3%) percent of any class of stock or securities of such company, so long as the Director has no active role in the publicly owned company as director, employee, consultant or otherwise.

(d) Insider Trading Guidelines. Director agrees to execute the Company’s Insider Trading Guidelines in the form previously approved by the Board.

(e) Remedies. The Director agrees that any breach of the terms of this Section 7 would result in irreparable injury and damage to the Company for which the Company would have no adequate remedy at law; the Director therefore also agrees that in the event of said breach or any threat of breach, the Company shall be entitled to an immediate injunction and restraining order to prevent such breach and/or threatened breach and/or continued breach by the Director and/or any and all entities acting for and/or with the Director, without having to prove damages, in addition to any other remedies to which the Company may be entitled at law or in equity. The terms of this paragraph shall not prevent the Company from pursuing any other available remedies for any breach or threatened breach hereof, including but not limited to the recovery of damages from the Director. The Director acknowledges that the Company would not have entered into this Agreement had the Director not agreed to the provisions of this Section 7.

The provisions of this Section 7 shall survive any termination of the Directorship Term, and the existence of any claim or cause of action by the Director against the Company, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of the covenants and agreements of this Section 7.

8. Indemnification. The Company agrees to indemnify the Director for her activities as a director of the Company to the fullest extent permitted by law, and to cover the Director under a directors and officers liability insurance obtained by the Company. Further, the Company and the Director agree to enter into an indemnification agreement substantially in the form of agreement entered into by the Company and its other Board members.

9. Non-Waiver of Rights. The failure to enforce at any time the provisions of this Agreement or to require at any time performance by the other party of any of the provisions hereof shall in no way be construed to be a waiver of such provisions or to affect either the validity of this Agreement or any part hereof, or the right of either party to enforce each and every provision in accordance with its terms. No waiver by either party hereto of any breach by the other party hereto of any provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions at that time or at any prior or subsequent time.
