ARTICLE 1. INTRODUCTION.

The Plan was adopted by the Board effective March 15, 1997. The purpose of the Plan is to promote the long-term success of the Company and the creation of stockholder value by (a) encouraging Employees, Outside Directors and Consultants to focus on critical long-range objectives, (b) encouraging the attraction and retention of Employees, Outside Directors and Consultants with exceptional qualifications and (c) linking Employees, Outside Directors and Consultants directly to stockholder interests through increased stock ownership. The Plan seeks to achieve this purpose by providing for Awards in the form of Restricted Shares or Options (which may constitute incentive stock options or nonstatutory stock options).

The Plan shall be governed by, and construed in accordance with, the laws of the State of Colorado (except their choice-of-law provisions).

ARTICLE 2. ADMINISTRATION.

2.1 Committee Composition. The Plan shall be administered by the Committee. The Committee shall consist exclusively of two or more directors of the Company, who shall be appointed by the Board. In addition, the composition of the Committee shall satisfy:

(a) Such requirements as the Securities and Exchange Commission may establish for administrators acting under plans intended to qualify for exemption under Rule 16b-3 (or its successor) under the Exchange Act; and

(b) Such requirements as the Internal Revenue Service may establish for outside directors acting under plans intended to qualify for exemption under section 162(m)(4)(C) of the Code.

The Board may also appoint one or more separate committees of the Board, each composed of one or more directors of the Company who need not satisfy the foregoing requirements, who may administer the Plan with respect to Employees and Consultants who are not considered officers or directors of the Company under section 16 of the Exchange Act, may grant Awards under the Plan to such Employees and Consultants and may determine all terms of such Awards.

2.2 Committee Responsibilities. The Committee shall (a) select the Employees, Outside Directors and Consultants who are to receive Awards under the Plan, (b) determine the type, number, vesting requirements and other features and conditions of such Awards, (c) interpret the Plan and (d) make all other decisions relating to the operation of the Plan. The Committee may adopt such rules or guidelines as it deems appropriate to implement the Plan. The Committee’s determinations under the Plan shall be final and binding on all persons.

ARTICLE 3. SHARES AVAILABLE FOR GRANTS.

3.1 Basic Limitation. Common Shares issued pursuant to the Plan may be authorized but unissued shares or treasury shares. The aggregate number of Options and Restricted Shares awarded under the Plan shall not exceed (a) 1,350,000 plus (b) the aggregate number of Common Shares remaining available for grants under the Predecessor Plans on March 15, 1997, plus (c) the additional Common Shares described in Sections 3.2 and 3.3. No additional grants shall be made under the Predecessor Plans after March 15, 1997. The limitation of this Section 3.1 shall be subject to adjustment pursuant to Article 9.

3.2 Annual Increase in Shares. As of January 1 of each year, commencing with the year 1998 and continuing through January 1, 2007, the aggregate number of Options and Restricted Shares that may be awarded under the Plan shall be increased by a number of Common Shares equal to the lesser of (a) 5% of the total number of Common Shares outstanding as of the next preceding December 3 1 or (b) 1,500,000. After the annual increase on January 1, 2007, there shall be no further annual increases under the Plan unless and until stockholder approval of such increase has been obtained.

3.3 Additional Shares. If Options granted under this Plan or under the Predecessor (Plans are forfeited or terminate for any other reason before being exercised, then the corresponding Common Shares shall become available for the grant of Options and Restricted Shares under this Plan. If Restricted Shares are forfeited, then the corresponding Common Shares shall again become available for the grant of NQOs and Restricted Shares under the Plan. The aggregate number of Common Shares that may be issued under the Plan upon the exercise of ISOs shall not be increased when Restricted Shares are forfeited.

ARTICLE 4. ELIGIBILITY.

4.1 Nonstatutory Stock Options and Restricted Shares. Only Employees, Outside Directors and Consultants shall be eligible for the grant of NQOs and Restricted Shares.

4.2 Incentive Stock Options. Only Employees who are common-law employees of the Company, a Parent or a Subsidiary shall be eligible for the grant of ISOs. In addition, an Employee who owns more than 10% of the total combined voting power of all classes of outstanding stock of the Company or any of its Parents or Subsidiaries shall not be eligible for the grant of an IS0 unless the requirements set forth in section 422(c)(6) of the Code are satisfied.

ARTICLE 5. OPTIONS.

5.1 Stock Option Agreement. Each grant of an Option under the Plan shall be evidenced by a Stock Option Agreement between the Optionee and the Company. Such Option shall be subject to all applicable terms of the Plan and may be subject to any other terms that are not inconsistent with the Plan. The Stock Option Agreement shall specify whether the Option is an IS0 or an NQO. The provisions of the various Stock Option Agreements entered into under the Plan need not be identical. Options may be granted in

consideration of a cash payment or in consideration of a reduction in the Optionee’s other compensation. A Stock Option Agreement may provide that a new Option will be granted automatically to the Optionee when he or she exercises a prior Option and pays the Exercise Price in the form described in Section 6.2.

5.2 Number of Shares. Each Stock Option Agreement shall specify the number of Common Shares subject to the Option and shall provide for the adjustment of such number in accordance with Article 9. Options granted to any Optionee in a single fiscal year of the Company shall not cover more than 500,000 Common Shares, except that Options granted to a new Employee in the fiscal year of the Company in which his or her service as an Employee first commences shall not cover more than one million Common Shares. The limitations set forth in the preceding sentence shall be subject to adjustment in accordance with Article 9.

5.3 Exercise Price. Each Stock Option Agreement shall specify the Exercise Price; provided that the Exercise Price under an IS0 shall in no event be less than 100% of the Fair Market Value of a Common Share on the date of grant and the Exercise Price under an NQO shall in no event be less than 85% of the Fair Market Value of a Common Share on the date of grant. In the case of an NQO, a Stock Option Agreement may specify an Exercise Price that varies in accordance with a predetermined formula while the NQO is outstanding.

5.4 Exercisability and Term. Each Stock Option Agreement shall specify the date when all or any installment of the Option is to become exercisable. The Stock Option Agreement shall also specify the term of the Option; provided that the term of an IS0 shall in no event exceed 10 years from the date of grant. A Stock Option Agreement may provide for accelerated exercisability in the event of the Optionee’s death, disability or retirement or other events and may provide for expiration prior to the end of its term in the event of the termination of the Optionee’s service. NQOs may also be awarded in combination with Restricted Shares, and such an Award may provide that the NQOs will not be exercisable unless the related Restricted Shares are forfeited.

5.5 Effect of Change in Control. The Committee may determine, at the time of granting an Option or thereafter, that such Option shall become exercisable as to all or part of the Common Shares subject to such Option in the event that a Change in Control occurs with respect to the Company, subject to the following limitations:

(a) In the case of an ISO, the acceleration of exercisability shall not occur without the Optionee’s written consent.

(b) If the Company and the other party to the transaction constituting a Change in Control agree that such transaction is to be treated as a “pooling of interests” for financial reporting purposes, and if such transaction in fact is so treated, then the acceleration of exercisability shall not occur to the extent that the surviving entity’s independent public accountants determine in good faith that such acceleration would preclude the use of “pooling of interests” accounting.

5.6 Modification or Assumption of Options. Within the limitations of the Plan, the Committee may modify, extend or assume outstanding options or may accept the cancellation of outstanding options (whether granted by the Company or by another issuer) in return for the grant of new options for the same or a different number of shares and at the same or a different exercise price. The foregoing notwithstanding, no modification of an Option shall, without the consent of the Optionee, alter or impair his or her rights or obligations under such Option.

5.7 Buyout Provisions. The Committee may at any time (a) offer to buy out for a payment in cash or cash equivalents an Option previously granted or (b) authorize an Optionee to elect to cash out an Option previously granted, in either case at such time and based upon such terms and conditions as the Committee shall establish.

ARTICLE 6. PAYMENT FOR OPTION SHARES.

6.1 General Rule. The entire Exercise Price of Common Shares issued upon exercise of Options shall be payable in cash or cash equivalents at the time when such Common Shares are purchased, except as follows:

(a) In the case of an IS0 granted under the Plan, payment shall be made only pursuant to the express provisions of the applicable Stock Option Agreement. The Stock Option Agreement may specify that payment may be made in any form(s) described in this Article 6.

(b) In the case of an NQO, the Committee may at any time accept payment in any form(s) described in this Article 6.

6.2 Surrender of Stock. To the extent that this Section 6.2 is applicable, all or any part of the Exercise Price may be paid by surrendering, Common Shares that are already owned by the Optionee. Such Common Shares shall be valued at their Fair Market Value on the date when the new Common Shares are purchased under the Plan. The Optionee shall not surrender, Common Shares in payment of the Exercise Price if such action would cause the Company to recognize compensation expense (or additional compensation expense) with respect to the Option for financial reporting purposes.

6.3 Exercise/Sale. To the extent that this Section 6.3 is applicable, all or any part of the Exercise Price and any withholding taxes may be paid by delivering (on a form prescribed by the Company) an irrevocable direction to a securities broker approved by the Company to sell all or part of the Common Shares being purchased under the Plan and to deliver all or part of the sales proceeds to the Company.

6.5 Promissory Note. To the extent that this Section 6.5 is applicable, all or any part of the Exercise Price and any withholding taxes may be paid by delivering (on a form prescribed by the Company) a full-recourse promissory note; provided that the par value of the Common Shares being purchased under the Plan shall be paid in cash or cash equivalents.

8.2 Payment for Awards. To the extent that an Award is granted in the form of newly issued Restricted Shares, the Award recipient, as a condition to the grant of such Award, shall be required to pay the Company in cash or cash equivalents an amount equal to the par value of such Restricted Shares. To the extent that an Award is granted in the form of Restricted Shares from the Company’s treasury, no cash consideration shall be required of the Award recipients. Any amount not paid in cash may be paid with a full recourse promissory note.

8.3 Vesting Conditions. Each Award of Restricted Shares may or may not be subject to vesting. Vesting shall occur, in full or in installments, upon satisfaction of the conditions specified in the Stock Award Agreement. A Stock Award Agreement may provide for accelerated vesting in the event of the Participant’s death, disability or retirement or other events. The Committee may determine, at the time of granting Restricted Shares or thereafter, that all or part of such Restricted Shares shall become vested in the event that a Change in Control occurs with respect to the Company, except as provided in the next following sentence. If the Company and the other party to the transaction constituting a Change in Control agree that such transaction is to be treated as a “pooling of interests” for financial reporting purposes, and if such transaction in fact is so treated, then the acceleration of vesting shall not occur to the extent that the surviving entity’s independent public accountants determine in good faith that such acceleration would preclude the use of “pooling of interests” accounting.

8.4 Voting and Dividend Rights. The holders of Restricted Shares awarded under the Plan shall have the same voting, dividend and other rights as the Company’s other stockholders. A Stock Award Agreement, however, may require that the holders of Restricted Shares invest any cash dividends received in additional Restricted Shares. Such additional Restricted Shares shall be subject to the same conditions and restrictions as the Award with respect to which the dividends were paid.

ARTICLE 9. PROTECTION AGAINST DILUTION.

9.1 Adjustments. In the event of a subdivision of the outstanding Common Shares, a declaration of a dividend payable in Common Shares, a declaration of a dividend payable in a form other than Common Shares in an amount that has a material effect on the price of Common Shares, a combination or consolidation of the outstanding Common Shares (by reclassification or otherwise) into a lesser number of Common Shares, a recapitalization, a spin-off or a similar occurrence, the Committee shall make such adjustments as it, in its sole discretion, deems appropriate in one or more of (a) the number of Options and Restricted Shares available for future Awards under Article 3, (b) the limitations set forth in Section 5.2, (c) the number of Common Shares covered by each outstanding Option or (d) the Exercise Price under each outstanding Option.

9.3 Reorganizations.
