(a) In consideration of the Company entering into this Agreement with the Manager, the Manager hereby agrees, for so long as the Manager is employed by the Company or one of its Affiliates and for a period of six (6) months after the date of termination of the Manager's employment (the "Noncompete Period"), that the Manager shall not (i) directly or indirectly, as an employee, agent, manager, director, officer, stockholder, partner or otherwise, own, manage, operate, control, be employed by, participate in or be connected in any manner whatsoever with the ownership, management, operation or control of any business in competition with the principal business activities in which the Company is engaged, or has material plans to engage in, at the time of the termination of the manager's employment, (ii) solicit from any company, or any division, department or subsidiary of any company, or any individual employed by any of the foregoing, any business relating to services similar to the services which were performed by the Company relating to the Company's principal business activities, its joint venturers or affiliates for such company during the Manager's employment by the Company or its Affiliates or (iii) request or cause any company to cancel or terminate any business relationship with the Company, its joint venturers or affiliates, or directly or indirectly solicit or otherwise cause any employee to terminate such employee's relationship with the Company, its joint venturers or affiliates. At the Company's option, the Noncompete Period may be extended for an additional three (3) month period (the "Noncompete Extension Period") if within one month of the termination of the Noncompete Period the Company gives the Manager notice of such extension and the Company pays the Manager an amount equal to one-fourth the Manager's annual base salary as of the date of termination of employment. Such amount shall be paid in installments in a manner consistent with the then current salary payment policies of the Company. At the Company's option, the Noncompete Extension Period may be extended for an additional three (3) month period pursuant to the provisions of the two preceding sentences. For purposes of this Section 23, "principal business activities" of the Company shall mean those business activities of the Company pursuant to which the Company has derived during the preceding twelve month period, or reasonably expects to derive within twelve months of the termination of the Manager's employment, ten percent (10%) or more of its consolidated revenues. 18 (b) The manager shall promptly and fully disclose to the Company, and with all Necessary detail for development, marketing; sale and installation, any and all know-how, discoveries, inventions, improvements, ideas, writings, formulae, processes and methods (whether copyrightable, patentable or otherwise) made, received, conceived, acquired or written by the Manager (whether or not at the request or upon the suggestion of the Company) during the term of the Manager's employment, solely or jointly with others, in or relating to any activities of the Company or an affiliate known to the Manager as a consequence of the Manager's employment (collectively referred to herein as the "Subject Matter"). (c) The Manager hereby assigns and transfers, and agrees to assign and transfer, to the Company, all right, title and interest in and to the Subject Matter, and the Manager further agrees' to execute, acknowledge and deliver all such further papers, including applications for copyrights and patents, as may be necessary to obtain copyrights or patents for any thereof in any and all countries and to vest title thereto to the Company. The Manager shall assist the Company in obtaining such copyrights or patents during the period of this Agreement and any time thereafter and to testify in any prosecution or litigation involving any of the Subject Matter. (d) The Manager shall not, during the period of this Agreement, or at any time thereafter, directly or indirectly, disclose or permit to be known, to any person, f inn or cooperation, any trade-secrets or confidential information acquired by him during the course of or as an incident to the employment hereunder, relating to the Company, its officers or directors, any company which the Manager has knowledge of or dealt with in the course of his employment by the Company, or any joint venture or affiliate of the Company, or in which any of the foregoing has a beneficial interest, including, but not limited to, the business affairs of each of the foregoing. Such confidential information shall include, but is not limited to, the Subject Matter as well as information relating to agreements, research, methods, writings, manuals, developments, marketing and any other document embodying such confidential information. Confidential information shall not include any information that (i) is in the public domain other than by reason of a breach hereof; or (ii) was in the possession of the Manager at the time of the disclosure; or (iii) was obtained by the Manager in good faith from a third party entitled to disclose it; or (iv) was required to be disclosed by a court of competent jurisdiction or a governmental authority with authority over the Company, in which case the Manager shall use the Manager's best efforts, prior to such disclosure, to give timely notice of such requirement to the Board of Directors of the Company which shall have the right to object to such disclosure or seek confidential treatment of the confidential information. (e) All names of actual or potential clients which have been solicited or are on any mailing lists, rolodex, files or directories in the possession or under the control of the Manager (whether in written, electronic or other formats), and all information and documents relating to the Company or its joint venturers or affiliates, shall be the-exclusive property of the Company and the Manager shall use the Manager's best efforts to prevent any publication or disclosure thereof. Upon termination of the Manager's employment with the Company, all names of actual or potential customers, documents, records, reports, writings and other similar documents containing confidential information, or trade-secrets including copies thereof, then in the Manager's possession or control shall be promptly returned to the Company. 19 (f) Notwithstanding clauses (a) and (d) above, if at any time a court holds that the restrictions stated in such clauses (a) and (d) are unreasonable or otherwise unenforceable under circumstances then existing, the parties hereto agree that the maximum period, scope or geographic area determined to be reasonable under such circumstances by such court will be substituted for the stated period, scope or area. The Manager and the Company recognize that the services to be rendered by the Manager are of a special, unique, unusual, extraordinary and intellectual character involving a high degree of skill and having a peculiar value, the loss of which may cause the Company immediate and irreparable harm which cannot be adequately compensated in damages. In the event of a breach or threatened breach by the Manager of this Agreement, the Manager consents that the Company shall be entitled to injunctive relief, both preliminary and permanent, without bond, and the Manager will not raise the defense that the Company has an adequate remedy at law. In addition, the Company shall be entitled to any other legal or equitable remedies as may be available under law.
