A transfer of shares of stock of the Company from IMS to an affiliated company, subsidiary or spin-off entity of IMS, or the reduction in ownership of capital stock of the Company by IMS by means of a spin-off of such shares to IMS stockholders or sales of shares into the public market, shall not alone be deemed to meet the requirements of clause (8)(e)(i) hereof.

Executive agrees that he will not disclose or use at any time, either during or after the Employment period, any Confidential Information without the written consent of the Board of Directors of the Company. Executive agrees to deliver to the Company at the end of the Employment period, or at any other time that the Company may request, all memoranda, notes, plans, records, documentation and other materials (and copies thereof) containing Confidential Information relating to the business of the Company and its subsidiaries, no matter where such material is located and no matter what form the material may be in, which Executive may then possess or have under his control. If requested by the Company, Executive shall provide to the Company written confirmation that all such materials have been delivered to the Company or have been destroyed. Executive shall take all appropriate steps to safeguard Confidential Information and to protect it against disclosure, misuse, espionage, loss and theft. (b) "Confidential Information" shall mean information which is not generally known to the public and which is used, developed, or obtained by the Company or its subsidiaries relating to the businesses of any of the Company and its subsidiaries or the business of any customer thereof including, but not limited to: products or services; fees, costs and pricing structure; designs; analyses; formulae; drawings; photographs; reports; computer software, including operating systems, applications, program listings, flow charts, manuals and documentation; databases; accounting and business methods; inventions and new developments and methods, whether patentable or unpatentable and whether or not reduced to practice; all copyrightable works; the customers of any of the Company and its subsidiaries and the Confidential Information of any customer thereof; and all similar and related information in whatever form. Confidential Information shall not include any information which (i) was rightfully known by Executive prior to the Employment Period; (ii) is publicly disclosed by law or in response to an order of a court or governmental agency; (iii) becomes publicly available through no fault of Executive or (iv) has been published in a form generally available to the public prior to the date upon which Executive proposes to disclose such information. Information shall not be deemed to have been published merely because individual portions of the information have been separately published, but only if all the material features comprising such information have been published in combination. 10. Inventions and Patents. In the event that Executive, as a part of Executive's activities on behalf of the Company, generates, authors or contributes to any invention, new development or method, whether or not patentable and whether or not reduced to practice, any copyrightable work, any trade secret, any other Confidential Information, or any information that gives any of the Company and its subsidiaries an advantage over any competitor, or similar or related developments or information related to the present or future business of any of the Company and its subsidiaries (collectively "Developments and Information"), Executive acknowledges that all Developments and Information are the exclusive property of the Company. Executive hereby assigns to the Company, its nominees, successors or assigns, all rights, title and interest to Developments and Information. Executive shall cooperate with the Company's Board of Directors to protect the interests of the Company and its subsidiaries in Developments and Information. Executive shall execute and file any document related to any Developments and Information requested by the Company's Board of Directors including applications, 8 powers of attorney, assignments or other instruments which the Company's Board of Directors deems necessary to apply for any patent, copyright or other proprietary right in any and all countries or to convey any right, title or interest therein to any of the Company's nominees, successors or assigns. 11. No Conflicts. (a) Executive agrees that in his individual capacity he will not enter into any agreement, arrangement or understanding, whether written or oral, with any supplier, contractor, distributor, wholesaler, sales representative, representative group or customer, relating to the business of the Company or any of its subsidiaries, without the express written consent of the Board of Directors of the Company. (b) As long as Executive is employed by the Company or any of its subsidiaries, Executive agrees that he will not, except with the express written consent of the Board of Directors of the Company, become engaged in, render services for, or permit his name to be used in connection with, any business other than the business of the Company, any of its subsidiaries or any corporation or partnership in which the Company or any of its subsidiaries have an equity interest. 12. Non-Competition Agreement. (a) Executive acknowledges that his services are of a special, unique and extraordinary value to the Company and that he has access to the Company's trade secrets, Confidential Information and strategic plans of the most valuable nature. Accordingly, Executive agrees that for the period of three (3) years following the Termination Date, Executive shall not directly or indirectly own, manage, control, participate in, consult with, render services for, or in any manner engage in any business competing with the businesses of the Company or any of its subsidiaries as such businesses exist or are in process of development on the Termination Date, including without limitation the publication of periodic research and analysis of the information technology industries. Nothing herein shall prohibit Executive from being a passive owner of not more than 1% of the outstanding stock of any class of a corporation which is publicly traded, so long as Executive has no active participation in the business of such corporation. (b) In addition, for a period of three (3) years commencing on the Termination Date, Executive shall not (i) induce or attempt to induce any employee of the Company or any subsidiary to leave the employ of the Company or such subsidiary, or in any way interfere with the relationship between the Company or any subsidiary and any employee thereof, (ii) hire directly or through another entity any person who was an employee of the Company or any subsidiary at any time during the Employment Period, or (iii) induce or attempt to induce any customer, supplier, licensee or other business relation of the Company or any subsidiary to cease doing business with the Company or such subsidiary, or in any way interfere with the relationship between any such customer, supplier, licensee or business relation and the Company or any subsidiary. (c) Executive agrees that these restrictions on competition and solicitation shall be deemed to be a series of separate covenants not-to-compete and a series of separate non-solicitation covenants for each month within the specified periods, separate covenants not-to-compete and non- 9 solicitation covenants for each state within the United States and each country in the world, and separate covenants not-to-compete for each area of competition. If any court of competent jurisdiction shall determine any of the foregoing covenants to be unenforceable with respect to the term thereof or the scope of the subject matter or geography covered thereby, such remaining covenants shall nonetheless be enforceable by such court against such other party or parties or upon such shorter term or within such lesser scope as may be determined by the court to be enforceable. (d) Because Executive's services are unique and because Executive has access to Confidential Information and strategic plans of the Company of the most valuable nature, the parties agree that the covenants contained in this Section 12 are necessary to protect the value of the business of the Company and that a breach of any such covenant would result in irreparable and continuing damage for which there would be no adequate remedy at law. The parties agree therefore that in the event of a breach or threatened breach of this Agreement, the Company or its successors or assigns may, in addition to other rights and remedies existing in their favor, apply to any court of competent jurisdiction for specific performance and/or injunctive or other relief in order to enforce, or prevent any violations of, the provisions hereof. 13.
