Employee hereby agrees that, during the Term, he shall not, directly or indirectly, as employee, agent, consultant, stockholder, director, co-partner or in any other individual or representative capacity, own, operate, manage, control, engage in, invest in or participate in any manner in, act as a consultant or advisor to, render services for (alone or in association with any person, firm, corporation or entity), or otherwise assist any person or entity that engages in or owns, invests in, operates, manages or controls any venture or enterprise that competes in the Business anywhere in the world (the "Territory"); provided, however, that nothing contained herein shall be construed to prevent Employee from investing in the stock of any competing corporation listed on a national securities exchange or traded in the over-the-counter market, but only if Employee is not involved in the business of said corporation and if Employee does not own more than an aggregate of two (2%) percent of the stock of such corporation. 2.3 NON-SOLICITATION. Without limiting the generality of the provisions of Section 2.2 above, Employee hereby agrees that during the Term he will not, directly or indirectly, solicit (or participate as employee, agent, consultant, stockholder, director, partner or in any other individual or representative capacity in any business which solicits), business from any person, firm, corporation or other entity that is a customer of the Company at the time of such solicitation, or from any successor in interest to any such person, firm, corporation or other entity, for the purpose of securing business or contracts relating to the Business. 2.4 INTERFERENCE WITH RELATIONSHIPS. During the Term, Employee shall not, directly or indirectly, as employee, agent, consultant, stockholder, director, co-partner or in any other individual or representative capacity: (a) employ or engage, or solicit for employment or engagement, any person employed or engaged by the Company, or otherwise seek to influence or alter any such person's relationship with the Company, or (b) solicit or encourage any customer of the Company to terminate or otherwise alter his, her or its relationship with the Company. 6 -7- 3.

The court in each case shall reduce the time period and/or Territory to permissible duration or size. 5. REMEDIES. Employee acknowledges and agrees that the covenants set forth in the Agreement are reasonable and necessary for the protection of the Company's business interests, that irreparable injury will result to the Company if Employee breaches any of the terms of said covenants, and that in the event of Employee's actual or threatened breach of any such covenant, the Company will have no adequate remedy at law. Employee accordingly agrees that in the event of any actual or threatened breach by him of any of the covenants contained herein, the Company shall be entitled to immediate temporary injunctive and other equitable relief, without bond and without 7 the necessity of showing actual monetary damages, subject to hearing as soon thereafter as possible. Nothing contained herein shall be construed as prohibiting the Company from pursuing any other remedies available to it for such breach or threatened breach, including the recovery of any damages which it is able to prove. 6. CONDITION OF EMPLOYMENT. The Company shall have no obligation to retain the Employee in its employ as a result of this Agreement, there shall be no inference as to the length of employment implied hereby, and the Company reserves the same rights to terminate the employment of the Employee as existed prior to the date hereof. 7. MISCELLANEOUS. This Agreement sets forth the entire agreement and understanding of the parties hereto with respect to the subject matter hereof and supersedes any other agreements between the parties, written or oral, relating to the subject matter hereof. No amendment or modification of this Agreement and no waiver by any party of the breach of any covenant contained herein shall be binding unless executed in writing by the party against whom enforcement of such amendment, modification or waiver is sought. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original without production of the others. This Agreement shall be governed by and construed in accordance with the laws of the State of Tennessee, without regard to its choice of law provisions. In the event any provision or portion of any provision of this Agreement is held invalid or unenforceable by a court of competent jurisdiction as applied to any fact or circumstance, the remaining provisions and portions of this Agreement and the same provision as applied to any other fact or circumstance shall not be affected or impaired thereby, and shall remain valid and enforceable.
