3. Non-Solicitation. During the Non-Competition Period, Seller shall not, and shall cause its Subsidiaries (other than the Transferred Subsidiaries) not to, (a) directly or indirectly, hire, engage or employ (as an employee, consultant or otherwise) any New Buyer Employee or other employees of Buyer other than any of the independent contractors set forth on Schedule I attached hereto (collectively, “Buyer Employees”), (b) through any director or officer of Seller, directly or indirectly, solicit for employment or the engagement of services of any Buyer Employee or induce or attempt to induce any Buyer Employee to leave his or her employment with Buyer, or in any way intentionally interfere with the employment relationship between any Buyer Employee and Buyer or any Affiliate of Buyer, in each case for the purpose of employing or engaging the services of such Buyer Employee or soliciting such Buyer Employee to become an employee or consultant of Seller or its Subsidiaries or any other Person; provided, however, that nothing herein shall preclude Seller from employing or soliciting any Buyer Employee (i) who independently responds to any public advertisement or general solicitation (such as a newspaper advertisement or internet posting) not specifically targeting such Buyer Employee or (ii) following the termination of such Buyer Employee’s employment with Buyer for any reason, provided, that Seller has not induced such Buyer Employee to terminate his or her employment in breach of Seller’s obligations hereunder, or (c) take any action or attempt to take any action with the intent of impairing any material relationship, contractual or otherwise, between the Buyer and any customer, supplier, consultant, independent contractor, distributor or reseller.

4. Confidentiality. The parties agree that the terms of the confidentiality provisions of Section 9.5 of the Purchase Agreement are incorporated herein as if fully set forth herein.

5. Reasonableness of Restrictions. Seller acknowledges and agrees that the restrictive covenants contained herein are necessary for the protection of the business investment by Buyer in the acquisition of the Acquired Assets pursuant to the Purchase Agreement and are reasonable in terms of time, geographic area, scope and content.

6. Severability. Any term or provision of this Agreement that a court deems invalid or unenforceable in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any

term or provision hereof is invalid or unenforceable, Buyer and Seller agree that the body making the determination of invalidity or unenforceability shall have the power to reduce the scope, duration or area of the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified after the expiration of the time within which the judgment may be appealed.

7. Remedies. Each of Buyer and Seller acknowledges and agrees that the other party would be damaged irreparably in the event any of the provisions of this Agreement are not performed in accordance with their specific terms or otherwise are breached, and that money damages or other legal remedies would not be an adequate remedy for any such damages. It is accordingly agreed that (i) the parties shall be entitled to (in a court of competent jurisdiction as set forth in Section 13) an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, without bond or other security being required, this being in addition to any remedy to which they are entitled under this Agreement, and (ii) the right of specific enforcement is an integral part of the transactions contemplated by this Agreement and without that right, neither Seller nor Buyer would have entered into this Agreement. Each of Seller and Buyer acknowledges and agrees that each Party shall be entitled to monetary damages for a willful or intentional breach of this Agreement. In no event shall any party be responsible and liable for any monetary damages or other amounts under this Agreement that are special, indirect, incidental, consequential, exemplary or punitive damages.

Each of Buyer and Seller (a) submits to the exclusive jurisdiction of the Court of Chancery of the State of Delaware (or any other federal or state court in the State of Delaware if it is determined that the Court of Chancery does not have jurisdiction over such action) in any action or proceeding arising out of or relating to this Agreement, (b) agrees that all claims in respect of such action or proceeding may be heard and determined only in any such court and (c) agrees not to bring any action or proceeding arising out of or relating to this Agreement in any other court.

Either party may make service on the other party by sending or delivering a copy of the process to the party to be served at the address and in the manner provided for the giving of notices in Section 12.
