AGREEMENT

1.Covenants Not to Compete or Interfere.



---





2.No Employment Contract; Termination.This Agreement is not an employment contract and by execution hereof the
parties do not intend to create an employment contract. This Agreement does not effect the Employee's rights under his existing employment contract.

3.Injunctive Relief; Damages.Upon a breach or threatened breach by Employee of any of the provisions of this
Agreement, the Company shall be entitled to an injunction restraining Employee from such breach without posting a bond. Nothing herein shall be construed as prohibiting the Company from pursuing any
other remedies for such breach or threatened breach, including recovery of damages from Employee.

4.Attorney's Fees.In any action to enforce any of the provisions of this Agreement, the prevailing party shall
be entitled to reasonable attorneys' fees and costs of investigation and litigation.

5.Severability.It is the desire and intent of the parties that the provisions of this Agreement shall be
enforced to the fullest extent permissible under the law. Accordingly, if any provision of this Agreement shall prove to be invalid or unenforceable, the remainder of this Agreement shall not be
affected thereby, and in lieu of each provision of this Agreement that is illegal, invalid or unenforceable, there shall be added as a part of this Agreement a provision as similar in terms to such
illegal, invalid or unenforceable provision as may be possible and be legal, valid and enforceable. In the event that a court finds any portion of Section 1 to be overly broad, and therefore
unenforceable, the parties intend that the court shall modify such portion of paragraph 1 to reflect the maximum restraint allowable, and shall enforce this Agreement and the covenants herein
as so modified.

6.Entire Agreement; Governing Law.This Agreement embodies the entire Agreement between the parties concerning
the subject matter hereof and replaces and supersedes any prior or contemporaneous negotiations, oral representations, agreements or understandings among or attributable to the parties hereto. The
provisions of this Agreement shall not limit or otherwise affect Employee's obligations under the provisions of any agreement with the Company with respect to the nondisclosure of the Company's
confidential information. This Agreement and all performances hereunder shall be governed by and construed in accordance with the laws of the State of Colorado.

7.Arbitration.If a dispute arises between the Employer and the Employee as to the interpretation of this
Agreement, the Employer and the Employee agree to submit the matter to binding arbitration in accordance with the Center for Public Resources Rules for Non-Administered Arbitration of
Business Disputes, as modified herein, by a sole arbitrator, in Denver, Colorado, selected in accordance with the provisions of Section 7(b). The arbitration shall be governed by the United
States Arbitration Act, 9 U.S.C. § 1-16, and judgment upon the award rendered by the arbitrator may be entered by any court having jurisdiction thereof.

8.Waiver of Jury Trial.Employee and the Company hereby agree to waive their respective rights to a jury trial
of any claim or cause of action based upon or arising out of this Agreement. The scope of this waiver is intended to be all encompassing of any and all disputes that may be filed in any court and that
relate to the subject matter of this Agreement, including without limitation, contract claims, tort claims, breach of duty claims, and all other common law and statutory claims. Employee and the
Company warrant and represent that each has reviewed this waiver with its legal counsel and that each knowingly and voluntarily waives its jury trial rights following consultation with legal counsel.
In the event of litigation, this Agreement may be filed as a written consent to a trial by the court.

9.Amendments; Waiver.This Agreement may not be altered or amended, and no right hereunder may be waived,
except by an instrument executed by each of the parties hereto. No waiver of any term, provision, or condition of this Agreement, in any one or more instances, shall be deemed to be or construed as a
further or continuing waiver of any such term, provision or condition or as a waiver of any other term, provision or condition of this Agreement.

10.Assignment.The Company may assign its rights and obligations under this Agreement to any subsidiary or
affiliate of the Company or to any acquirer of substantially all of the business of the Company, and all covenants and Agreements hereunder shall inure to the benefit of and be enforceable by or
against any such assignee. Neither the Agreement nor any rights or duties hereunder may be assigned or delegated by Employee.

11.Binding Effect.Except as otherwise provided herein, this Agreement shall be binding upon and shall inure to
the benefit of the parties hereto and their respective legal representatives, heirs, successors and assigns.
