1. Definitions.  Except as expressly indicated herein, defined terms used in this Agreement have the meanings set forth in the Plan.    

2. Grant of RSUs.  Subject to the terms and conditions hereinafter set forth and the terms and conditions of the Plan, the Company, with the approval and at the direction of the Committee, hereby grants to the Participant the number of RSUs indicated above.

3. Vesting and Forfeiture of RSUs.

(a) Vesting of RSUs.  The RSUs subject to this Award shall be subject to the restrictions contained in this Agreement and subject to forfeiture to the Company unless and until the RSUs have vested in accordance with the terms and conditions of this Agreement.  Subject to the terms and conditions of this Agreement, the RSUs will vest in full on the Vesting Date indicated above or upon the Accelerated Vested Date (as defined herein) provided the Participant remains continuously employed by the Company from the Grant Date until the respective Vesting Date or Accelerated Vesting Date (as defined in Section 3(b) below).

(b) Acceleration of Vesting.  Notwithstanding the foregoing subparagraph (a), in the event that prior to the Vesting Date: (1) the Committee determines that the Participant’s employment was terminated as a result of the Participant's medically diagnosed permanent physical or mental inability to perform his or her duties as an employee of the Company (“Disability”), (2) the Participant’s employment terminates due to the Participant’s death, or (3) the Company undergoes a Change in Control, then all of the unvested RSUs will vest immediately upon the earliest of any such event to occur, if any.  Any vesting date described in this Section 3(b) shall be referred to herein as an “Accelerated Vesting Date.”

(c) Forfeiture.  In the event, in any case prior to the Vesting Date or any Accelerated Vesting Date, of (1) the Participant ceasing to provide services as an employee other than under circumstances that would result in an Accelerated Vesting Date, (2) Participant attempting to sell, assign, transfer or otherwise dispose of, or mortgage, pledge or otherwise encumber any unvested RSUs or (3) any unvested RSUs becoming subject to attachment or any similar involuntary process, then any unvested RSUs shall be forfeited by the Participant to the Company, and the Participant shall thereafter have no right, title or interest whatever in such RSUs.

(d) Effect of Vesting; Issuance of Unrestricted Stock.  The vested RSUs will be settled upon the first to occur of (i) the Vesting Date, (ii) the Participant’s “separation from service” as defined in Section 409A(a)(2)(A)(i) of the Code and the treasury regulations promulgated thereunder (a “Separation from Service”),  (iii) a Change in Control, and (iv) the Participant’s death (the “Settlement Date”).  Upon the Settlement Date and pursuant to the terms and conditions set forth in this Agreement, the Company will issue (subject to Sections 11 and 15 below) to the Participant a certificate or electronically transfer by book-entry the number of shares of Common Stock of the Company equal to the number of vested RSUs which are to be settled, which shares of Common Stock shall be free of any transfer or other restrictions arising under this Agreement.

4. Adjustment of RSUs.  The number of RSUs subject to this Award will automatically adjust to prevent accretion, or to protect against dilution, in the event of a change to the Company’s Common Stock resulting from a recapitalization, stock split, consolidation, spin-off, reorganization, or liquidation or other similar transactions and any transaction in which shares of Common Stock are changed into or exchanged for a different number or kind of shares of stock or other securities of the Company or another corporation as provided under Section 9 of the Plan.

5. No Rights as a Stockholder.  As of the Grant Date, the Participant shall have no rights as a stockholder of the Company with respect to the RSUs (including voting rights and the right to receive dividends and other distributions), except as otherwise specifically provided in this Agreement; provided that dividends and other distributions paid on the Common Stock shall be credited to the Participant in an amount equal to the amount that would have been payable or distributable to the Participant had the Common Stock underlying the RSUs been issued and outstanding as of the record date for such dividend or distribution, to be held by the Company on the Participant's behalf and made subject to the same vesting conditions applicable to the underlying RSUs.   At the time of delivery of the underlying shares of Common Stock, the Company shall distribute to the Participant in cash all dividends or distributions previously paid with respect to the RSUs that vested hereunder without interest.  In the event the Participant forfeits RSUs, the Participant shall also immediately forfeit any dividends or distributions held by the Company that are attributable to the Common Stock underlying such forfeited RSUs.

6. Non-Transferability of Award.  The RSUs shall not be assignable or transferable by the Participant prior to their vesting in accordance with Section 3 of this Agreement.  In addition, RSUs shall not be subject to attachment, execution or other similar process prior to vesting.

7. No Right to Continued Service.  The granting of the Award shall not be construed as granting to the Participant any right to continue services with the Company as an employee. 

8. Amendment of RSUs Award.  The Award or the terms of this Agreement may be amended by the Board or the Committee at any time (a) if the Board or the Committee determines, in its reasonable discretion, that amendment is necessary or advisable in the light of any addition to or change in the Code or in the regulations issued thereunder, or any federal or state securities law or other law or regulation, which change occurs after the Grant Date and by its terms applies to the Award; provided that, such amendment shall not materially and adversely affect the rights of the Participant hereunder; or (b) other than in the circumstances described in clause (a), with the consent of the Participant.

9. Notice.  Any notice to the Company provided for in this Agreement shall be addressed to the Company in care of its Secretary at its executive offices at 1401 Wynkoop, Suite 500, Denver, Colorado 80202, and any notice to the Participant shall be addressed to the Participant at the current address shown on the payroll records of the Company. Any notice shall be deemed to be duly given if and when properly addressed and posted by registered or certified mail, postage prepaid.

10. Beneficiary.  The Participant may file with the Board a written designation of a beneficiary on such form as may be prescribed by the Board and may, from time to time, amend or revoke such designation. If no designated beneficiary survives the Participant, the executor or administrator of the Participant’s estate shall be deemed to be the Participant’s beneficiary.

11. Tax Consequences and Withholding.  As of the Grant Date, or at any time thereafter as requested by the Company, the Participant hereby authorizes minimum required withholding from payroll and any other amounts payable to the Participant, and otherwise agrees to make adequate provision for, the minimum sums required to be withheld to satisfy the federal, state, local and foreign tax withholding obligations of the Company, if any, which arise in connection with the Award.  Unless the tax withholding obligations of the Company, if any, are satisfied, the Company shall have no obligation to issue a certificate or book-entry transfer for such shares.  The Participant acknowledges that s(he) is solely responsible for paying all taxes attributable to this Award.

12. Governing Plan Document.  The Award is subject to all the provisions of the Plan, the provisions of which are hereby made a part of this Agreement, and is further subject to all interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant to the Plan.
