2.         Definition of "Fair Market Value". For purposes of this Agreement, the "Fair Market Value" of the Shareholder's Shares means the amount that would be received by the Shareholder pursuant to the Corporation 's Amended and Restated Certificate of Incorporation if the Corporation was liquidated and dissolved and its sole assets at the time of such liquidation and di ssolution consisted of cash in an amount equal to the amount which a hypothetical willing buyer would pay a hypothetical willing seller(s) in cash for one hundred percent (I 00%) of the then outstanding capital stock of the Corporation, with all in-the-money options and warrants for capital stock having been exercised in accordance with their respective terms, in an arm's-length transaction, with neither buyer nor seller(s) being under any undue pressure to complete the transaction, and with all parties having equal access to, and accurate knowledge of, all material facts.

3.         Delivery of the Shares. Thirty (30) days after the delivery of a Notice of Exercise (the "Date of Transfer"), the Shares referenced therein will be transferred to the Corporation without the need for further action on the part of any party to this Agreement, regardless of whether there is then pending any arbitration or dispute as to the proper amount of the purchase price for the Shares referenced in the Notice of Exercise, and the then acting Secretary of the Corporation shall reflect the transfer on the books of the Corporation. On or before the Date of Transfer, the Shareholder shall physically deliver to the then acting Secretary of the Corporation any and all share certificates that represent ownership of any of the Shareholder's Shares to be transferred pursuant to the Notice of Exercise. The Shareholder hereby irrevocably appoints the then acting Secretary of the Corporation as his attorney-in-fact to effect the transfer of the Shares contemplated by this Agreement, without the need for further action on the part of the Shareholder.

4.         Payment of Purchase Price. The purchase price for any Shares purchased pursuant to the terms and provisions of this Agreement shall be paid to the Shareholder by the Corporation delivering a promissory note (the "Note") to the Shareholder on or before the Date of Transfer. The Note shall bear interest at the Applicable Federal Rate (short-term), as published by the Internal Revenue Service, in effect as of the Date of Transfer. Interest shall accrue from the Date of Transfer and shall be paid on an annual basis upon each anniversary of the Date of Transfer, until such time as a final payment of principal is made, whereupon all accrued but unpaid interest shall become due. Principal payments on the Note shall be due as follows: ten percent (10%) at the Date of Transfer, ten percent (10%) at the six (6) month anniversary of the Date of Transfer, twenty percent (20%) at the one (I) year anniversary of the Date of Transfer, forty percent (40%) at the two (2) year anniversary of the Date of Transfer, and the remainder at the three (3) year anniversary of the Date of Transfer. The Corporation may, in its sole discretion, prepay the Note in whole or in part at any time without penalty.

5.         Arbitration. If the Shareholder delivers a Notice of Alternative Valuation within the fifteen (15) day period set forth in Section I (d) above, and the Corporation of such Notice of Alternative Valuation does not expressly accept the proposed purchase price stated in the Notice of Alternative Valuation within five (5) business days after delivery, then the Shareholder shall have the right to commence arbitration. Arbitration must be commenced within sixty (60) days after the Date of Transfer. Arbitration shall be conducted in Denver, Colorado, in accordance with the Commercial Arbitration Rules of the American Arbitration Association (expedited procedures) then in effect. There shall be three (3) arbitrators, all of whom shall be neutral, and at least one (1) of whom shall be an attorney who has been licensed to practice law in the State of Colorado for at least ten (10) years. The arbitrators shall have the authority to exclude evidence found to be irrelevant, redundant, or prejudicial beyond its probative value, and shall be authorized and directed to exercise that authority consistently for the purpose of expediting the proceeding. The arbitration shall be conducted as a "baseball style'· arbitration, in which the arbitrators will only consider the two proposed purchase prices set forth in the Notice of Exercise and the Notice of Alternative Valuation, and in which the arbitrators shall be required to determine which one of the two proposed purchase prices is closest to the Fair Market Value of the Shares. The proposed purchase price that the arbitrators identify as being closest to the Fair Market Value of the Shares will be the purchase price for the purchase, sale, and transfer of the Shares under the Purchase Option and. for any other appropriate purpose. will be the Fair Market Value of the Shares as of the date of termination of the Shareholder's employment with the Corporation. The arbitrators may order specific performance, preliminary and final injunctive relief, and other equitable relief. The award of the arbitrators may be entered and enforced in any court of competent jurisdiction. Should the arbitrators accept the valuation originally presented in the Notice of Exercise, then the Shareholder shall be liable for all of the costs of arbitration, including the fees of the arbitrators and the reasonable attorney's fees of the Corporation incurred in connection therewith. Any dispute or controversy arising under or in connection with this Agreement, other than one involving a determination of the fair market value of the Shareholder's Shares, shall be finally settled and determined by binding arbitration in Denver, Colorado, under the same rules and procedures as those stated in this Section 5, except that the provision regarding "baseball style" arbitration shall not apply.

6.         Termination of Agreement. This Agreement shall terminate on the occurrence of any one or more of the following events: (i) the cessation of business by the Corporation, (ii) the bankruptcy, receivership, or assignment for the benefit of creditors of all of the assets of the Corporation, (iii ) the dissolution of the Corporation, (iv) the signing of a written agreement by the Shareholder and the Corporation which expressly terminates this Agreement, or (v) when the Corporation is no longer a private entity, e.g., there is a public market for its securities.

7.         Amendment. This Agreement may only be amended by written agreement of the Shareholder and the Corporation.

8.         Binding Effect. This Agreement shall be binding upon the Shareholder and his respective heirs and legal representatives and upon the Corporation and its successors and assigns.

9.         Choice of Law. This Agreement shall be construed m accordance with the internal laws, and not the conflict of law rules, of Colorado.

11.       Employment by Subsidiary. If the Shareholder ceases to be employed by the Corporation because he becomes an employee of a wholly-owned subsidiary of the Corporation, the term "Corporation" as used in this Agreement shall refer to such wholly-owned subsidiary.
