1.

Confidential Information prepared or compiled by the Participant and/or the Company or furnished to the Participant during the Participant’s employment with the Company shall be the sole and exclusive property of the Company, and none of such Confidential Information or copies thereof, shall be retained by the Participant.  The Participant acknowledges that the Company does not voluntarily disclose Confidential Information, but rather takes precautions to prevent dissemination of Confidential Information beyond those employees such as the Participant entrusted with such information.  The Participant further acknowledges that the Confidential Information: (i) is entrusted to the Participant because of the Participant’s position with the Company; and (ii) is of such value and nature as to make it reasonable and necessary for the Participant to protect and preserve the confidentiality and secrecy of the Confidential Information.  The Participant acknowledges and agrees that the Confidential Information is a valuable, special, and a unique asset of the Company, the disclosure of which could cause substantial injury and loss of profits and goodwill to the Company.  While the Participant may not disclose any such Confidential Information, the Participant has the right to discuss wages, benefits or other terms and conditions

of employment.  Nothing in this Agreement, including the definition of “Confidential Information” above and the nondisclosure requirements in Section 1(b) is intended to restrict the Participant’s right to have such discussions. 

(i)

The Participant shall hold all Confidential Information in strict confidence.  The Participant shall not, during the period of the Participant’s employment or at any time thereafter, disclose to anyone, or publish, use for any purpose, exploit, or allow or assist another person to use, disclose or exploit, except for the benefit of the Company, without prior written authorization, any Confidential Information or part thereof, except as permitted:  (1) in the ordinary course of the Company’s business or the Participant’s work for the Company; or (2) by law.  The Participant shall use all reasonable precautions to assure that all Confidential Information is properly protected and kept from unauthorized persons.  Further, the Participant shall not directly or indirectly, use the Company’s Confidential Information or information regarding the names, contact information, skills and compensation of employees and contractors of the Company to: (1) call upon, solicit business from, attempt to conduct business with, conduct business with, interfere with or divert business away from any customer, client, vendor or supplier of the Company with whom or which the Company conducted business within the eighteen (18) months prior to the Participant’s termination from employment with the Company; and/or (2)  recruit, solicit, hire or attempt to recruit, solicit, or hire, directly or by assisting others, any persons employed by or associated with the Company.  The Participant agrees that the Participant shall take all steps necessary to safeguard all Confidential Information and prevent its wrongful use, disclosure, or dissemination of any other person or entity.  The Participant further agrees that in the event the Participant is subpoenaed, served with any legal process or notice or otherwise requested to produce or divulge, directly or indirectly, any Confidential Information by any entity, agency, or person in any formal or informal proceeding including, but not limited to, any interview, deposition, administrative or judicial hearing and/or trial, and upon the Participant’s receipt of such subpoena, process, notice or request, the Company requests that the Participant notify and deliver via overnight delivery service a copy of the subpoena, process, notice or other request to: the Company’s General Counsel at 6250 LBJ Freeway, Dallas, Texas 75240.

(ii)

The Participant shall immediately notify the Company’s General Counsel if the Participant learns of or suspects any unauthorized disclosure of Confidential Information concerning the Company.

(iii)

Subject to Section 1(b)(iv), the Participant agrees that the Participant shall not use or disclose any confidential or trade secret information belonging to any former employer or third party, and the Participant shall not bring onto the premises of the Company or onto any the Company property any

confidential or trade secret information belonging to any former employer or third party without such third parties’ consent.    

(iv)

During the Participant’s employment, the Company will receive from third parties their confidential and/or proprietary information, subject to a duty on the Company’s part to maintain the confidentiality of and to use such information only for certain limited purposes.  The Participant agrees to hold all such confidential or proprietary information in the strictest confidence and not to disclose it to any person or organization or to use it except as necessary in the course of the Participant’s employment with the Company and in accordance with the Company’s agreement with such third party.

(c)

Return of the Company Property.  Upon the termination of the Participant’s employment for any reason, the Participant shall immediately return and deliver to the Company any and all property, including, without limitation, Confidential Information, software, devices, data, reports, proposals, lists, correspondence, materials, equipment, computers, hard drives, papers, books, records, documents, memoranda, manuals, e-mail, electronic or magnetic recordings or data, including all copies thereof, books of account, drawings, prints, plans, and the like which belong to the Company or which relate to the Company’s business and which are in the Participant’s possession, custody or control, whether prepared by the Participant or others.  If at any time after termination of the Participant’s employment, for any reason, the Participant determines that the Participant has any Confidential Information in the Participant’s possession or control, the Participant shall immediately return to the Company all such Confidential Information in the Participant’s possession or control, including all copies and portions thereof.  Further, the Participant shall not retain any property, including, without limitation, Confidential Information, data, information, or documents, belonging to the Company or any copies thereof (in electronic or hard copy format).  

2.

Non-Solicitation.  In Section 1, the Company promised to provide the Participant certain Confidential Information.  The Participant recognizes and agrees that:  (i) the Company has devoted a considerable amount of time, effort, and expense to develop its Confidential Information and business goodwill; (ii) the Company’s Confidential Information and business goodwill are valuable assets to the Company; and (iii) any unauthorized use or disclosure of the Confidential Information would cause irreparable harm to the Company for which there is no adequate remedy at law, including damage to the Company’s business goodwill.  To protect the Confidential Information and business goodwill of the Company, the Participant agrees to the following restrictive covenants.

(a)

Non-Solicitation.  The Participant agrees that, as part of the Participant’s employment or association with the Company, the Participant will become familiar with the salary, pay scale, capabilities, experiences, skill and desires of the Company’s employees and consultants.  For these reasons, the Participant agrees that to protect the Company’s Confidential Information, legitimate business interests, and business goodwill, it is necessary to enter into the

following restrictive covenant.  The Participant agrees that, during the Participant’s employment and for a period of twelve (12) months following the date on which the Participant’s employment with the Company terminates for any reason (“Restrictive Covenant Period”), the Participant, whether directly or indirectly, shall not recruit, solicit, hire or attempt to recruit, solicit, or hire, directly or by assisting others, any persons employed by or associated with the Company, nor shall the Participant contact or communicate with any such persons for the purpose of inducing such persons to terminate their employment or association with the Company.  For purposes of this paragraph, the “persons” covered by this prohibition include current employees and persons who were employed by the Company within twelve (12) months of the time of the attempted recruiting, solicitation, or hiring.   

(b)

Remedies.  The Participant acknowledges that the restrictions contained in Section 1 and Section 2, in view of the nature of the Company’s business, are reasonable and necessary to protect their legitimate business interests, business goodwill and reputation, and that any violation of these restrictions would result in irreparable injury and continuing damage to the Company, and that money damages would not be a sufficient remedy to the Company for any such breach or threatened breach.  Therefore, the Participant agrees that the Company shall be entitled to a temporary restraining order and injunctive relief restraining the Participant from the commission of any breach or threatened breach of Section 1 or Section 2, without the necessity of establishing irreparable harm or the posting of a bond, and to recover from the Participant damages incurred by the Company as a result of the breach, as well as the Company’s attorneys’ fees, costs and expenses related to any breach or threatened breach of this Agreement and enforcement of this Agreement.  Nothing contained in this Agreement shall be construed as prohibiting the Company from pursuing any other remedies available to it for any breach or threatened breach, including, without limitation, the recovery of money damages, attorneys’ fees, and costs.  The existence of any claim or cause of action by the Participant against the Company, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of the restrictive covenants contained in Section 1 or Section 2, or preclude injunctive relief.

(c)

Tolling. If the Participant violates any of the restrictions contained in this Section 2, the Restrictive Covenant Period shall be suspended and shall not run in favor of the Participant until such time that the Participant cures the violation to the satisfaction of the Company; the period of time in which the Participant is in breach shall be added to the Restrictive Covenant Period.

(d)

Notice.  If the Participant, in the future, seeks or is offered employment, or any other position or capacity with another company or entity, the Participant agrees to inform each new employer or entity, before accepting employment, of the existence of the restrictions in Section 1 and Section 2. The Company shall be entitled to advise such person or subsequent employer of the provisions of Section 1 and Section 2 and to otherwise deal with such person to ensure that the provisions of Section 1 and Section 2 are enforced and duly discharged.
