6. NON-DISCLOSURE

(a) Confidential Information. By virtue of his employment with the Company, the Executive will have access to confidential, proprietary, and highly sensitive information relating to the business of the Company and which is a valuable, competitive and unique asset of the Company (“Confidential Information”), the confidentiality of which is essential to the Company’s ability to differentiate its products and services. Such Confidential Information includes all information which relates to the business of the Company, which is or has been disclosed to the Executive orally or in writing by the Company or obtained by virtue of work performed for the Company, is or was developed by the Company, and is not generally available to or known by individuals or entities within the industry in which the Company is or may become engaged or readily accessible by independent investigation. The Confidential Information sought to be protected includes, without limitation, information pertaining to: (i) the identities of customers and clients with which or whom the Company does or seeks to do business, as well as the point of contact persons and decision-makers at these customers and clients, including their names, addresses, e-mail addresses and positions; (ii) the past or present purchasing history and the past and/or current job requirements of each past and/or existing customer and client; (iii) the volume of business and the nature of the business relationship between the Company and its customers and clients; (iv) the pricing of the Company’s services, including any deviations from its standard pricing for particular customers and clients; (v) the Company’s business plans and strategy, including customer or client assignments and rearrangements, sales and administrative staff expansions, marketing and sales plans and strategy, proposed adjustments in compensation of sales personnel, revenue, expense and profit projections, industry analyses, and any proposed or actual implemented technology changes; (vi) information regarding the Company’s employees, including their identities, skills, talents, knowledge, experience, and compensation; (vii) the Company’s financial results and business condition; and (viii) computer programs and software developed by the Company and tailored to the Company’s needs by its employees, independent contractors, consultants or vendors; (ix) information relating to the Company’s architects, designers, contractors, or persons likely to become architects, designers, or contractors; (x) any past or present merchandise or supply sources in the future; (xi) technical and non-technical information including patent, copyright, trade secret, proprietary information, methods, ideas, concepts, designs, inventions, know-how, processes, software programs, software source documents and formulae related to the current, future and proposed products and services of the Company including research, experimental work, development, design details and specifications and engineering, financial statements, forecasts, plans (whether business, strategic, marketing or other), client lists, prospective client lists, sales data, sales analysis, equipment and other assets, prices, costs, sources of supplies, pricing methods, personnel, marketing research, and business relationships, whether or not marked “Confidential” or “Proprietary”. Confidential Information may be contained on the Company’s computer network, in computerized documents or files, or in any written or printed documents, including any written reports summarizing such information.

(b) Non-Disclosure of Confidential Information. The Executive acknowledges that the Company’s Confidential Information will be disclosed to

37

the Executive throughout his employment at the Company in order to enable the Executive to perform his duties for the Company. The Executive further acknowledges that, prior to his employment at the Company, Executive was either unfamiliar with the Company’s Confidential Information or Executive developed such Confidential Information for the benefit of the Company and was otherwise compensated for such services outside of the terms of this Agreement. Finally, Executive acknowledges that the unauthorized disclosure of Confidential Information could place the Company at a competitive disadvantage. Consequently, Executive agrees (i) not to use, publish, disclose or divulge, directly or indirectly, at any time, any Confidential Information for his own benefit and for the benefit of any person, entity, or corporation other than the Company, to any person who is not a current employee of the Company, without the express, written consent of the Company and except in the performance of the duties assigned to him by the Company; (ii) not to make copies of Confidential Information without the prior written consent of the Company; (iii) to take reasonable precautions to protect against the inadvertent disclosure of such Confidential Information or theft or misappropriation by others; and (iv) not to use such Confidential Information except in connection with the specific duties of the Executive in connection with his employment.

(c) Notwithstanding the foregoing, the confidentiality and nondisclosure provisions contained herein with respect to any portion of the Confidential Information shall terminate when the Executive can document that the Confidential Information:

(i) was in the public domain at the same time it was communicated to the Executive by the Company;

(ii) entered the public domain subsequent to the time it was communicated to the Executive by the Company through no fault of the Executive;

(iii) was in the Executive’s possession free of any obligation of confidence at the time it was communicated to the Executive by the Company;

(iv) was rightfully communicated to the Executive free of any obligation of confidence subsequent to the time it was communicated to the Executive by the Company;

(v) was developed by the Executive independently of and without any reference to any information communicated to the Executive by the Company; or

(vi) Was communicated in response to a valid subpoena or order by a court or by a governmental body, provided that the Executive complies with the provisions of Section 6(e) below.

(d) Survival of Executive’s Obligations. Executive understands and agrees that his obligations under this Section shall survive the termination of this Agreement and/or his employment with the Company. Executive further

38

understands and agrees that his obligations under this Section are in addition to, and not in limitation or preemption of, all other obligations of confidentiality which he may have to the Company under general legal or equitable principles, or other policies implemented by the Company.

(e) Certain Disclosures. In the event that the Executive receives a request to disclose all or any part of the Confidential Information under the terms of a subpoena or order issued by a court or by a governmental body, the Executive agrees (i) to notify the Company immediately of the existence, terms, and circumstances surrounding such request, (ii) to consult with the Executive on the advisability of taking legal available steps to resist or narrow such request, and (iii) if disclosure of such Confidential Information is required to prevent the Executive from being held in contempt or subject to other penalty, to furnish only such portion of the Confidential Information as, in the opinion of counsel to the Executive, it is legally compelled to disclose and to exercise its best efforts to obtain an order or other reliable assurance that confidential treatment will be accorded to the disclosed Confidential Information.

7. RETURN OF COMPANY PROPERTY

Executive acknowledges that all memoranda, notes, correspondence, databases, computer discs, computer files, computer equipment and/or accessories, pagers, telephones, passwords or pass codes, records, reports, manuals, books, papers, letters, CD Roms, keys, Internet database access codes, client profile data, job orders, client and customer lists, contracts, software programs, information and records, drafts of instructions, guides and manuals, and other documentation (whether in draft or final form), and other sales, financial or technological information relating to the Company’s business, and any and all other documents containing Confidential Information furnished to Executive by any representative of the Company or otherwise acquired or developed by him in connection with his association with the Company (collectively, “Recipient Materials”) shall at all times be the property of the Company. Within twenty-four (24) hours of the termination of his employment for any reason, Executive will return to the Company any Recipient Materials which are in his possession, custody or control.

8. NON-SOLICITATION OF CUSTOMERS/CLIENTS

(a) Access to Confidential Information. Executive acknowledges that the special relationship of trust and confidence between him, the Company, and its clients and customers creates a high risk and opportunity for Executive to misappropriate the relationship and goodwill existing between the Company and its clients and customers. Executive further acknowledges and agrees that it is fair and reasonable for the Company to take steps to protect itself from the risk of such misappropriation. Executive further acknowledges that, at the outset of his employment with the Company and/or throughout his employment with the Company, Executive has been or will be provided with access to and informed of the Company’s Confidential Information, which will enable him to benefit from the Company’s goodwill and know-how.

(b) Inevitable Disclosure. Executive acknowledges that it would be inevitable in the performance of his duties as a director, officer, employee, investor, agent or consultant of any person, association, entity, or company which

39

competes with the Company, or which intends to or may compete with the Company, to disclose and/or use the Company’s Confidential Information, as well as to misappropriate the Company’s goodwill and know-how, to or for the benefit of such other person, association, entity, or company. Executive also acknowledges that, in exchange for the execution of the non-solicitation restriction set forth in this Section 8(b), he has received substantial, valuable consideration, including the consideration set forth in Sections 3 and 5 above. Executive further acknowledges and agrees that this consideration constitutes fair and adequate consideration for the execution of the non-solicitation restriction set forth in this Section.

(c) Non-Solicitation of Customers. Ancillary to the enforceable promises set forth in this Agreement including, without limitation, the promises contained in Sections 3, 6 and 7, as well as to protect the vital interests described in those Sections, Executive agrees that, while he is employed by the Company and for a period of twelve (12) months following the termination of his employment with the Company, regardless of the reason for such termination, Executive will not, without the prior written consent of the Company, directly or indirectly, alone or for his own account, or as owner, partner, investor, member, trustee, officer, director, shareholder, employee, consultant, distributor, advisor, representative or agent of any partnership, joint venture, corporation, trust, or other business organization or entity, (i) contact, solicit sales of, or sell, deliver or place any product, service or system of the kind and character sold, provided, distributed or placed by Executive on behalf of the Company to any person, association, corporation or other business organization or entity that Executive contacted, solicited, called upon, or served, or that he directed others to solicit, call upon, or serve, on behalf of the Company, during his employment at the Company; or (ii) contact, solicit, or seek to divert the business or patronage of any person, association, corporation, or other business organization or entity with whom or which Executive had business relations on behalf of the Company or with whom or which he met or communicated, or with whom or which he directed others to meet or communicate, for the purpose of offering to sell or place or solicit for sale or placement any product, service, or system of the kind and character sold, provided or distributed by him, on behalf of the Company, during his employment at the Company.

(d) Reasonable Restrictions. Executive agrees that the restriction set forth above is ancillary to an otherwise enforceable agreement, is supported by independent valuable consideration, and that the limitations as to time, geographical area, and scope of activity to be restrained by this Section are reasonable and acceptable, and do not impose any greater restraint than is reasonably necessary to protect the goodwill and other business interests of the Company. Executive agrees that if, at some later date, a court of competent jurisdiction determines that the non-solicitation agreement set forth in this Section does not meet the criteria set forth in Tex. Bus. & Comm. Code Ann. 15.50(2), this Section may be reformed by the court and enforced to the maximum extent permitted under Texas law.

(e) Breach. If Executive is found to have violated any of the provisions of this Section, Executive agrees that the restrictive period of each covenant so

40

violated shall be extended by a period of time equal to the period of such violation by him. Executive understands that his obligations under this Section shall survive the termination of his employment with the Company and shall not be assignable by him.

9. NON-SOLICITATION OF EMPLOYEES AND CONSULTANTS

Executive acknowledges that, as part of his employment or association with the Company, he will become familiar with the salary, pay scale, capabilities, experiences, skill and desires of the Company’s employees. In order to protect the confidentiality of such information, Executive agrees that, for a period of twelve (12) months following the termination of his employment with the Company, whether such termination occurs at the insistence of Executive or the Company, Executive shall not recruit, hire, solicit, or attempt to recruit, hire or solicit, directly or by assisting others, any other employees or consultants employed by or associated with the Company, nor shall he contact or communicate with any other employees or consultants of the Company for the purpose of inducing other employees or consultants to terminate their employment or association with the Company. For purposes of this covenant, “other employees or consultants” shall refer to permanent employees, temporary employees, or consultants who were employed by, doing business with, or associated with the Company within six (6) months of the time of the attempted recruiting, hiring or solicitation. Executive’s obligations under this Section 9 shall survive the termination of this Agreement and Executive’s employment with the Company.

10. REMEDIES

In the event that Executive violates any of the provisions set forth in Sections 6, 7, 8, or 9 of this Agreement, he acknowledges that the Company will suffer immediate and irreparable harm which cannot be accurately calculated in monetary damages. Consequently, Executive acknowledges and agrees that the Company shall be entitled to immediate injunctive relief, either by temporary or permanent injunction, to prevent such a violation. Executive further acknowledges and agrees that this injunctive relief shall be in addition to any other legal or equitable relief, including monetary damages, to which the Company would be entitled.

(d) Obligation to Assign Inventions to the Company. The Executive shall not be obligated to assign to the Company any Invention made by him during the Relationship or after termination of this Agreement which does not relate to any business or activity in which the Company is or may become engaged, except that the Executive is so obligated if the same relates to or is based on Confidential Information to which the Executive shall have had access during and by virtue of his employment or arises out of work assigned to him by the Company; nor shall the Executive be obligated to assign any Inventions which relate to or would be useful in any business or activities in which the Company is engaged if such Invention was conceived and reduced by practice by the Executive prior to this Agreement with the Company, provided that all such Inventions are listed on Exhibit A attached hereto and made known to the Company.
