Confidential Information Richard A.

Activity Against Company's Interest For the period of the employment of Richard A. Sandberg as Consultant to the President of the Company and for a period of two years after the termination of that employment, Richard A. Sandberg will not engage or otherwise be involved, either directly or indirectly, in the recruitment of the Company's employees or take any other action ad-verse to the management of the Company. Notwithstanding the foregoing, the parties agree that Richard A.

Non Competition Richard A. Sandberg will not compete with any business activity of the Company during his employment with the Company and for a period of two years after the termination of that employment.

Sandberg's employment with the Company terminates. The obligation in this paragraph shall not be violated by Richard A. Sandberg's ownership of shares of stock in a corporation involved in such activities provided such shares are publicly traded, Richard A. Sandberg owns less than two percent of the total number of issued and outstanding shares and Richard A. Sandberg is not otherwise connected with or active in, the business of such corporation. The parties recognize that the Company's business is carried on by telephone and from time to time in person in each of the 50 States of the United States of America and therefore that Richard A. Sandberg's Agreement not to compete must apply in all such 50 States. 14. Remedies For Breach Of Certain Covenants The parties acknowledge that because Richard A. Sandberg has been an officer and director of the Company and as such was and remains conversant with and had access to, the business, affairs, records, trade secrets, customers and customer lists, suppliers, supplier lists, patents, technical know-how, chemicals, devices, sales or distribution agents and representatives, sales or distribution agents and representatives lists, and other con-fidential and proprietary information of the Company, his compliance with Sections 10, 11, 12 and 13 of this Agreement is necessary to protect the goodwill and other proprietary interests of the Company and a breach of said covenants and agreements in this Agreement will result in continuing and irreparable damage to the Company for which there will be no adequate remedy at law. Therefore, the parties acknowledge that in the event of a breach of Richard A. Sandberg's commitments in Sections 10, 11, 12 or 13 of this Agreement, the Company shall be entitled, if it so elects, to institute and prosecute proceedings in any court of competent jurisdiction either in law or in equity to obtain damages for any breach of this Agreement and/or to enforce the specific performance thereof by Richard A. Sandberg and/or to enjoin Richard A. Sandberg from retaining Company property, using confidential Company information, competing with the Company or soliciting or recruiting its employees or otherwise acting against the Company's interests. 15. Release And Waiver Richard A. Sandberg, on behalf of himself, his executors, administrators and assigns, hereby releases the Company, its affiliates, and their respective directors, officers, agents, employees, benefit plans, fiduciaries and administrators of such benefit plans and their successors and assigns (hereinafter "Released Parties") from any and all claims or causes of action of any kind, other than vested rights under benefit plans or claims to enforce this Agreement, arising on or before the effective date of this Agreement, which Richard A. Sandberg has, had or may have against any of them, whether or not now known, including but not limited to, any claims arising from Richard A.

Covenant Not To Sue Richard A. Sandberg on behalf of himself, his heirs, executors, administrators and assigns, further agrees never directly or indirectly to commence or prosecute, or to permit or advise to be commenced or prosecuted, any action, proceeding, or charge against any Released Party, in any state or federal court, administrative agency or arbitral forum with respect to any matter other than to enforce this Agreement, whether or not now known, for any claim whatsoever (including but not limited to, any claim arising from Richard A. Sandberg's employment or officership with the Company, or the termination thereof) based upon any act, transaction, practice, conduct, or omission that occurred prior to the effective date of this Agreement, which he now has, or claims to have, or which at any time heretofore had, or which at any time hereafter may have. This covenant includes but is not limited to, rights under the Age Discrimination in Employment Act or any other federal, state, or local laws prohibiting age, race, sex, national origin, religion, or other forms of discrimination, claims for breach of contract or promissory estoppel or tort, and claims growing out of any legal restrictions on the Company's right to terminate its employees or officers. 17. Non Admission The parties recognize and agree that this Agreement does not and shall not constitute an admission of liability or wrongdoing by Richard A. Sandberg or the Company or its present or former affiliates, directors, officers, agents, employees. 18. No Abridgment of Indemnification Nothing in this Agreement is intended to limit or abridge any indemnification the Company would otherwise provide Richard A. Sandberg of and from any claims based on his actions as an officer or director of the Company. 19. Intent To Be Enforced As Fully As Possible In the event that any of the terms or provisions of this Agreement shall violate any statutory provision or may be otherwise unlawful or inoperative, it is the intent of the parties that this Agreement operate and be of full force and effect insofar as it does not violate said statutory provisions or is otherwise lawful and that this Agreement be carried out as far as possible in a manner consistent with its intent. 20. Litigation Costs In the event Richard A. Sandberg does not exercise his rights to revoke this Agreement in accordance with Section 24 and files a claim, lawsuit or complaint against the Company in any court or governmental agency with respect to the claims released under this Agreement, Richard A. Sandberg shall be liable for all costs and expenses including legal fees, incurred by any Released Party in defense of that action. 21. Voluntariness Richard A. Sandberg represents that he has carefully read and completely understands this Agreement and that he has entered into this Agreement voluntarily after having had an opportunity to consult with his legal advisors, which he has been encouraged to do in writing by the Company. (Attachment A) 22. Time To Review Richard A. Sandberg acknowledges that he has been advised he has 21 days to review the waivers and releases contained in this Agreement if he so chooses. 23. Adequacy Of Consideration Richard A. Sandberg acknowledges that the commitments, waivers and releases he gives in this Agreement are in exchange for valuable consideration to which he is not otherwise entitled. 24. Revocation Option Richard A. Sandberg shall have seven (7) days after the execution of this Agreement to revoke the waivers and releases in this Agreement and the Agreement shall not be effective unless and until those seven (7) days have lapsed without Richard A. Sandberg so revoking. 25.
