5.2 Non-Competition Provisions.

(a)       For a period of five (5) years commencing on the Closing Date (the "Restricted Period"), the Seller shall not, and shall not permit any of its or his Affiliates to, directly or indirectly, (i) engage in or assist others in engaging in the Restricted Business in the Territory; (ii) have an interest in any Person that engages directly or indirectly in the Restricted Business in the Territory in any capacity, including as a partner, shareholder, member, employee, principal, agent, trustee or consultant; or (iii) intentionally interfere in any material respect with the business relationships (whether formed prior to or after the date of this Agreement) between the Company and customers or suppliers of the Company.

(d)       The Seller acknowledges that the restrictions are all a part of the Personal Goodwill transferred to the Buyer which the Seller has been adequately compensated that a breach or threatened breach of this Section 5.2 would give rise to irreparable harm to the Buyer, for which monetary damages would not be an adequate remedy, and hereby agrees that in the event of a breach or a threatened breach by the Seller of any such obligations, the Buyer shall, in addition to any and all other rights and remedies that may be available to it in respect of such breach, be entitled to equitable relief, including a temporary restraining order, an injunction, specific performance and any other relief that may be available from a court of competent jurisdiction (without any requirement to post bond).

(e)       The Seller acknowledges that the restrictions contained in this Section 5.2 are reasonable and necessary to protect the legitimate interests of the Buyer and constitute a material inducement to the Buyer to enter into this Agreement and consummate the transactions contemplated by this Agreement. In the event that any covenant contained in this Section 5.2 should ever be adjudicated to exceed the time, geographic, product or service, or other limitations permitted by applicable law in any jurisdiction, then any court is expressly empowered to reform such covenant, and such covenant shall be deemed reformed, in such jurisdiction to the maximum time, geographic, product or service, or other limitations permitted by applicable law. The covenants contained in this Section 5.2 and each provision hereof are severable and distinct covenants and provisions. The invalidity or unenforceability of any such covenant or provision as written shall not invalidate or render unenforceable the remaining covenants or provisions hereof, and any such invalidity or unenforceability in any jurisdiction shall not invalidate or render unenforceable such covenant or provision in any other jurisdiction.
