        (a)    General.    In consideration of the payment of the Purchase Price, and in order to induce the Buyer to enter into this Agreement and to consummate the transactions contemplated hereby, Seller hereby covenants and agrees as follows:

          (i)  Without the prior written consent of the Buyer, the Seller shall not for a period of five (5) years from and after the Closing Date (A) directly or indirectly acquire or own in any manner any interest in any person, firm, partnership, corporation, association or other entity which engages or plans to engage in any business that competes with the Business as presently conducted anywhere in the world (the "Territory"), (B) be employed by or serve as an employee, agent, officer, director of, or as a consultant to, any person, firm, partnership,

corporation, association or other entity which engages or plans to engage in any business that competes with the Business as presently conducted within the Territory, or (C) utilize its special knowledge of the Business and its relationships with customers, suppliers and others to compete with the Business as presently conducted; provided, however, that nothing herein shall be deemed to prevent the Seller from acquiring through market purchases and owning, solely as an investment, less than three percent (3%) in the aggregate of the equity securities of any class of any issuer whose shares are registered under §12(b) or 12(g) of the Securities Exchange Act of 1934, as amended, and are listed or admitted for trading on any United States national securities exchange or are quoted on the National Association of Securities Dealers Automated Quotation System, or any similar system of automated dissemination of quotations of securities prices in common use, so long the Seller is not a member of any "control group" (within the meaning of the rules and regulations of the United States Securities and Exchange Commission) of any such issuer. The Seller acknowledges and agrees that the covenants provided for in this Article 7.7(a) are reasonable and necessary in terms of time, area and line of business to protect the Buyer's trade secrets. The Seller further acknowledges and agrees that such covenants are reasonable and necessary in terms of time, area and line of business to protect the Buyer's legitimate business interests, which include its interests in protecting the Buyer's (i) valuable confidential business information, (ii) substantial relationships with customers throughout the Territory, and (iii) customer goodwill associated with the ongoing Business. Seller expressly authorizes the enforcement of the covenants provided for in this Article 7.7(a) by (A) the Buyer and its subsidiaries, (B) the Buyer's permitted assigns, and (C) any successors to the Buyer's business. To the extent that the covenants provided for in this Article 7.8(a) may later be deemed by a court to be too broad to be enforced with respect to its duration or with respect to any particular activity or geographic area, the court making such determination shall have the power to reduce the duration or scope of the provision, and to add or delete specific words or phrases to or from the provision. The provision as modified shall then be enforced.

         (ii)  Without the prior consent of Buyer, the Seller shall not for a period of five (5) years from the Closing Date, directly or indirectly, for itself or for any other person, firm, corporation, partnership, association or other entity, (i) attempt to employ or enter into any contractual arrangement with any employee or former employee of the Buyer, unless such employee or former employee has not been employed by Buyer for a period of at least nine (9) months or unless terminated by Buyer for any reason, and/or (ii) call on or solicit any of the actual or targeted prospective customers or clients of the Business, nor shall the Seller make known the names and addresses of such customers or any information relating in any manner to the Business relationships with such customers. The parties hereby agree and acknowledge that the value of this Article 7.7 non-compete provision is One Hundred Fifty Thousand and 00/100 ($150,000.00).

        (iii)  The Seller shall not at any time divulge, communicate, use to the detriment of the Buyer or for the benefit of any other person or persons, or misuse in any way, any Confidential Information pertaining to the Business. Any confidential information or data now known by the Seller with respect to the Business shall be deemed a valuable, special and unique asset of the Buyer that is received by the Seller in confidence and as a fiduciary, and the Seller shall remain a fiduciary to the Buyer with respect to all of such information.

        (b)    Injunction.    It is recognized and hereby acknowledged by the parties hereto that a breach or violation by the Seller of any or all of the covenants and agreements contained in this Article 7.7 may cause irreparable harm and damage to Buyer in a monetary amount which may be virtually impossible to ascertain. As a result, the Seller recognizes and hereby acknowledges that Buyer shall be entitled to an injunction from any court of competent jurisdiction enjoining and restraining any breach or violation of any or all of the covenants and agreements contained in this Article 7.7 by the Seller and/or its associates, affiliates, partners or agents, either directly or indirectly, and that such right to injunction shall be cumulative and in addition to whatever other

rights or remedies the Buyer may possess hereunder, at law or in equity. Nothing contained in this Article 7.7 shall be construed to prevent Buyer from seeking and recovering from the Seller damages sustained by it as a result of any breach or violation by such entity or person of any of the covenants or agreements contained herein.

        ARTICLE 7.8    Delivery of Property Received by Seller and Buyer After Closing.    From and after the Closing, Buyer shall have the right and authority to collect, for the account of Buyer, all items which shall be transferred or are intended to be transferred to Buyer as part of the Assets as provided in this Agreement, and to endorse with the name of the Seller any checks or drafts received on account of any such Assets. The Seller agrees that it will transfer or deliver to Buyer, promptly after the receipt thereof, any cash or other property which the Seller receives after the Closing Date in respect of any claims, contracts, licenses, leases, commitments, sales orders, purchase orders, or any other items transferred or intended to be transferred to Buyer as part of the Assets under this Agreement. Buyer agrees that it will transfer or deliver to Seller, promptly after the receipt thereof, any cash or other property which the Buyer receives after the Closing Date in respect of any claims, contracts, licenses, leases, commitments, sales orders, purchase orders, or any other items not transferred or not intended to be transferred to Buyer as part of the Assets under this Agreement.

        ARTICLE 7.9    Buyer Appointed Attorney for the Seller.    Effective at the Closing Date, the Seller hereby constitutes and appoints Buyer, and Buyer's successors and assigns, its true and lawful attorney, in the name of either Buyer or the Seller (as Buyer shall determine in its sole discretion) but for the benefit and at the expense of Buyer (except as otherwise herein provided), (a) to institute and prosecute all proceedings which Buyer may deem proper in order to collect, assert or enforce any claim, right or title of any kind in or to the Assets as provided for in this Agreement; (b) to defend or compromise any and all actions, suits or proceedings in respect of any of the Assets, and to do all such acts and things in relation thereto as Buyer shall reasonably deem advisable; and (c) to take all action which Buyer may reasonably deem proper in order to provide for Buyer the benefits under any of the Assets where any required consent of another party to the sale or assignment thereof to Buyer pursuant to this Agreement shall not have been obtained after notice to Seller. The Seller acknowledges that the foregoing powers are coupled with an interest and shall be irrevocable. Buyer shall be entitled to retain for its own account any amounts respecting the Assets collected pursuant to the foregoing powers, including any amounts payable as interest in respect thereof.

        ARTICLE 7.10    Assignment of Contracts.    Prior to Closing, Seller shall obtain the consent of customers to assign the Assumed Contracts to Buyer in those Assumed Contracts which require such consent. At the option of Buyer, and notwithstanding anything in this Agreement to the contrary, this Agreement shall not constitute an assignment of any claim, contract, license, franchise, lease, commitment, sales order, sales contract, supply contract, service agreement, purchase order or purchase commitment if an attempted assignment thereof without the consent of a third party thereto would constitute a breach thereof or in any way adversely affect the rights of Buyer thereunder. If such consent is not obtained, or if any attempt at an assignment thereof would be ineffective or would affect the rights of the Seller thereunder so that Buyer would not in fact receive all such rights, the Seller shall cooperate with Buyer to the extent necessary to provide for Buyer the benefits under such claim, contract, license, franchise, lease, commitment, sales order, sales contract, supply contract, service agreement, purchase order or purchase commitment, including enforcement for the benefit of Buyer, at Buyer's expense, of any and all rights of the Seller against a third party thereto arising out of the breach or cancellation by such third party or otherwise.
