Restrictive Covenants. 10.1 Employee agrees that he will not, either during his employment or at any time after cessation of such employment, impart or disclose any of the Confidential Information to any person, firm or corporation other than Company, or use any of such Confidential Information, directly or indirectly for the Employee's own benefit or for the benefit of any person, firm or corporation other than Company or its affiliates. Employee's obligations under this Section 10.1 shall cease with respect to any such Confidential Information if such information (i) was already known to Employee at the time of disclosure, free of any obligation to keep it confidential, or (ii) was subsequently disclosed to Employee without breach of this Agreement by a third person who rightfully received and disclosed it without breaching any confidentiality obligation to the Company. It is also understood by the parties that Employee may be required to disclose Confidential Information (a) pursuant to subpoena or other court process, (b) at the express direction of any other authorized government agency or (c) otherwise as required by law or regulation. Disclosure of Confidential Information or any part thereof in such circumstances will not constitute a breach of the confidentiality provisions set forth in this Agreement, provided that Employee notifies Company in advance of any such disclosure and cooperates with Company in any efforts that Company may make to seek a protective order with respect to such disclosure. 10.2 In addition to the foregoing agreements relating to the Company's Confidential Information, during the term of this Agreement (including any renewals thereof) and during the term of the "Post-Employment Period" (as defined herein), Employee will not, without the 8 -8- Company's prior written consent, (i) solicit any of the employees of Company for the purpose of hiring or retaining any such employees, (ii) hire or retain or cause to be hired or retained any of the employees of Company or (iii) become involved in any manner, including without limitation as an officer, director, employee. consultant, representative, partner, owner or shareholder (except as a holder of less than a two percent (2%) equity interest in a public entity) in any business located in the United States which is in the business of inventing, developing, manufacturing, marketing, providing or selling products competitive with the products that the Company has developed, manufactured, marketed, produced or sold, or is in the process of developing (and reasonably expect to bring to market within one (1) year after the expiration of the Post-Employment Period or longer if required by the U.S. Food and Drug Administration clearance or approval process), manufacturing, marketing, producing or selling as of the date that Employee's employment terminates. For purposes of this Agreement, the term "PostEmployment Period" shall mean. the period commencing on the date that this Agreement is terminated for any reason and ending one (1) year from the date of such termination; provided, however, that in the event this Agreement expires or terminates for any reason prior to July 3, 1998, the restrictive provisions of this Section 10.9 shall not apply and there will be no "Post-Employment Period." 10.3 Employee agrees that all memoranda, lab books, notes, records, charts, formulae, specifications, lists and other documents made, compiled, received, held or used by Employee while employed by Company, concerning any phase of Company's business or its Confidential Information, shall be Company's property and shall be delivered by Employee to Company upon termination of Employee's employment or at any earlier time on the request of Company. 10.4 Employee acknowledges that given his access to information regarding Company, the provisions of this Section 10 are reasonable and necessary to protect Company's business. Employee further acknowledges that Employee has carefully reviewed the provisions of this Section 10, that Employee fully understands the economic consequences thereof, that Employee has assessed the respective advantages and disadvantages to Employee of entering into this Agreement and Employee has concluded that. in light of Employee's education, skills and abilities, the restrictions set forth in this Section 10 will not prevent Employee from earning a living after the termination of this Agreement. Employee agrees that each of the provisions of this Section 10, including, without limitation, the period of time, geographical area and types and scope of the restrictions on Employee's activities specified herein, are intended to be and shall be divisible. Employee further acknowledges that reasonableness of these provisions as an integral part of the terms of Employee's employment. If any provision of this Section 10 (including any sentence, clause or part thereof) shall be adjudicated to be invalid or unenforceable, such provision shall be deemed amended to delete therefrom the portion thus adjudicated to be invalid or unenforceable, such deletion to apply only with respect to the operation of such provision in the particular jurisdiction in which such adjudication is made. In addition, if any particular 9 -9- provision contained in this Agreement shall for any reason be held to be excessively broad as to duration, geographical scope, activity or subject, it shall be construed by limiting and reducing such provision as to such characteristic so that the provision is enforceable to the fullest extent compatible with the applicable law as it shall then appear. 10.5 As it would be very difficult to measure the damages which would result to Employer from a breach of any of the covenants contained in this Section 10 in the event of such a breach, Company shall have the right to have such covenants specifically enforced by a court of competent jurisdiction. Employee hereby recognizes and acknowledges that irreparable injury or damage shall result to the business of Company in the event of a breach or threatened breach by Employee of the terms and provisions of this Section 10. Therefore, Employee agrees that Company shall be entitled to an injunction restraining Employee from engaging in any activity constituting such breach or threatened breach. Nothing contained herein shall be construed as prohibiting Company from pursuing any other remedies available to Company at law or in equity for such breach or threatened breach, including, but not limited to, recovery of damages from Employee and, if Employee is still employed by Company, terminating the employment of Employee in accordance with the terms and provisions hereof. 10.6 Employee agrees that during his employment hereunder and for six (6) months thereafter, Employee will not attempt to solicit or induce any other employee of the Company to leave his or her employment with the Company or interfere with the business relationship between the Company and its suppliers or customers. 11.
