6

under applicable laws for any information disclosed under such order or at the election of Employer, cooperate with Employer’s effort to obtain such confidential treatment.

(b)                                 Non-Compete.  During the Employment Term and for one (1) year immediately following a termination of employment for any reason, Executive shall not, without the prior written consent of the Employer, participate or engage in, directly or indirectly (as an owner, partner, employee, officer, director, independent contractor, consultant, advisor or in any other capacity calling for the rendition of services, advice, or acts of management, operation or control) any business for an individual or entity whose principal business involves coal mining or coal marketing in the following regions: Central Appalachia, Northern Appalachia, Illinois Basin, Western Colorado, and any other region in which the Employer or any of the Employer’s subsidiaries conduct business.

(c)                                  Non-Solicitation.  During the Employment Term and for two (2) years immediately following a termination of Employment for any reason, Executive shall not, without the prior written consent of the Employer, solicit or induce any then-existing employee of the Employer or any of its subsidiaries or affiliates to leave employment with the Employer or any of its subsidiaries or affiliates, or contact any then-existing customer or vendor under contract with the Employer or any of its affiliates or subsidiaries for the purpose of obtaining business similar to that engaged in, or received (as appropriate), by the Employer or any of its affiliates or subsidiaries.

(f)                                    Remedies.  Executive acknowledges that the protections of the Employer set forth in this Section 8 are fair and reasonable, and that any violation of such protections would cause serious and irreparable harm and damage to the Employer and its subsidiaries and affiliates.  Executive agrees that remedies at law for a breach or threatened breach of the provisions of this Section 8 would be inadequate and, therefore, the Employer shall be entitled, in addition to any other available remedies (including money damages), without posting a bond, to equitable relief in the form of specific performance, temporary restraining order, temporary or permanent injunction, or any other equitable remedy that may be then available.

(g)                                 Limitation.  The terms of this Section 8 are intended to limit disclosure and competition by the Executive to the maximum extent permitted by law.  If the duration, scope, or nature of any limitation or restriction imposed by any provision of this Section 8 is

7

finally determined by any court or tribunal of competent jurisdiction to be in excess of what is valid and enforceable under applicable law, such provision shall be construed to cover only that duration, scope or activity that is valid and enforceable.  Executive hereby acknowledges that this Section 8 shall be given the construction which renders its provisions valid and enforceable to the maximum extent, not exceeding its express terms, possible under applicable law.

10.                                 Representations of Executive.  Executive hereby represents to the Employer that Executive has full lawful right to enter into this Agreement and carry out Executive’s duties hereunder, and that performance of Executive’s obligations hereunder will not constitute a breach of or default under any employment, confidentiality, non-competition or other agreement.  Executive further represents to the Employer that Executive is not listed in the Office of Surface Mining’s Applicant Violator System database.  Executive shall provide prompt notice to the Employer of Executive’s first employment subsequent to a termination of employment.
