SECTION 1. ESTABLISHMENT AND PURPOSE.

The purpose of the Plan is to offer selected persons an opportunity to acquire a proprietary interest in the success of the Company, or to increase such interest, by purchasing Shares of the Company’s Stock. The Plan provides both for the direct award or sale of Shares and for the grant of Options to purchase Shares. Options granted under the Plan may include Nonstatutory Options as well as ISOs intended to qualify under Section 422 of the Code.

Capitalized terms are defined in Section 12.

SECTION 2. ADMINISTRATION.

(a) Committees of the Board of Directors . The Plan may be administered by one or more Committees. Each Committee shall consist of one or more members of the Board of Directors who have been appointed by the Board of Directors. Each Committee shall have such authority and be responsible for such functions as the Board of Directors has assigned to it. If no Committee has been appointed, the entire Board of Directors shall administer the Plan. Any reference to the Board of Directors in the Plan shall be construed as a reference to the Committee (if any) to whom the Board of Directors has assigned a particular function.

(b) Authority of the Board of Directors . Subject to the provisions of the Plan, the Board of Directors shall have full authority and discretion to take any actions it deems necessary or advisable for the administration of the Plan. All decisions, interpretations and other actions of the Board of Directors shall be final and binding on all Purchasers, all Optionees and all persons deriving their rights from a Purchaser or Optionee.

SECTION 3. ELIGIBILITY.

(a) General Rule . Only Employees, Outside Directors and Consultants shall be eligible for the grant of Nonstatutory Options or the direct award or sale of Shares. Only Employees shall be eligible for the grant of ISOs.

(b) Ten-Percent Stockholders . A person who owns more than 10% of the total combined voting power of all classes of outstanding stock of the Company, its Parent or any of its Subsidiaries shall not be eligible for designation as an Optionee or Purchaser unless (i) the Exercise Price is at least 110% of the Fair Market Value of a Share on the date of grant, (ii) the Purchase Price (if any) is at least 100% of the Fair Market Value of a Share and (iii) in the case of an ISO, such ISO by its terms is not exercisable after the expiration of five years from the date of grant. For purposes of this Subsection (b), in determining stock ownership, the attribution rules of Section 424(d) of the Code shall be applied.

SECTION 4. STOCK SUBJECT TO PLAN.

(a) Basic Limitation . Not more than 15,168,031 ¹ Shares may be issued under the Plan (subject to Subsection (b) below and Section 8) plus 1,681,623 shares of Series A-1 Preferred Stock. ² The number of Shares that are subject to Options or other rights outstanding at any time under the Plan shall not exceed the number of Shares that then remain available for issuance under the Plan. The Company, during the term of the Plan, shall at all times reserve and keep available sufficient Shares to satisfy the requirements of the Plan. Shares offered under the Plan may be authorized but unissued Shares or treasury Shares.

(b) Additional Shares . In the event that Shares previously issued under the Plan are reacquired by the Company pursuant to a forfeiture provision, right of repurchase or right of first refusal, such Shares shall be added to the number of Shares then available for issuance under the Plan. However, the aggregate number of Shares issued upon the exercise of ISOs (including Shares reacquired by the Company) shall in no event exceed 200% of the number specified in Subsection (a) above. In the event that an outstanding Option or other right for any reason expires or is canceled, the Shares allocable to the unexercised portion of such Option or other right shall not reduce the number of Shares available for issuance under the Plan.

SECTION 5. TERMS AND CONDITIONS OF AWARDS OR SALES.

(a) Stock Purchase Agreement . Each award or sale of Shares under the Plan (other than upon exercise of an Option) shall be evidenced by a Stock Purchase Agreement between the Purchaser and the Company. Such award or sale shall be subject to all applicable terms and conditions of the Plan and may be subject to any other terms and conditions which are not inconsistent with the Plan and which the Board of Directors deems appropriate for inclusion in a Stock Purchase Agreement. The provisions of the various Stock Purchase Agreements entered into under the Plan need not be identical.

(b) Duration of Offers and Nontransferability of Rights . Any right to acquire Shares under the Plan (other than an Option) shall automatically expire if not exercised by the Purchaser within 30 days after the grant of such right was communicated to the Purchaser by the Company. Such right shall not be transferable and shall be exercisable only by the Purchaser to whom such right was granted.

(c) Purchase Price . The Purchase Price of Shares to be offered under the Plan shall not be less than 85% of the Fair Market Value of such Shares, and a higher percentage may be required by Section 3(b). Subject to the preceding sentence, the Board of Directors shall determine the Purchase Price at its sole discretion. The Purchase Price shall be payable in a form described in Section 7.

2

(d) Withholding Taxes . As a condition to the purchase of Shares, the Purchaser shall make such arrangements as the Board of Directors may require for the satisfaction of any federal, state, local or foreign withholding tax obligations that may arise in connection with such purchase.

(e) Restrictions on Transfer of Shares and Minimum Vesting . Any Shares awarded or sold under the Plan shall be subject to such special forfeiture conditions, rights of repurchase, rights of first refusal and other transfer restrictions as the Board of Directors may determine. Such restrictions shall be set forth in the applicable Stock Purchase Agreement and shall apply in addition to any restrictions that may apply to holders of Shares generally. In the case of a Purchaser who is not an officer of the Company, an Outside Director or a Consultant:

(i) Any right to repurchase the Purchaser’s Shares at the original Purchase Price (if any) upon termination of the Purchaser’s Service shall lapse at least as rapidly as 20% per year over the five-year period commencing on the date of the award or sale of the Shares;

(ii) Any such right may be exercised only for cash or for cancellation of indebtedness incurred in purchasing the Shares; and

(iii) Any such right may be exercised only within 90 days after the termination of the Purchaser’s Service.

SECTION 6. TERMS AND CONDITIONS OF OPTIONS.

(a) 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. The Option shall be subject to all applicable terms and conditions of the Plan and may be subject to any other terms and conditions which are not inconsistent with the Plan and which the Board of Directors deems appropriate for inclusion in a Stock Option Agreement. The provisions of the various Stock Option Agreements entered into under the Plan need not be identical.

(b) Number of Shares . Each Stock Option Agreement shall specify the number of Shares that are subject to the Option and shall provide for the adjustment of such number in accordance with Section 8. The Stock Option Agreement shall also specify whether the Option is an ISO or a Nonstatutory Option.

(c) Exercise Price . Each Stock Option Agreement shall specify the Exercise Price. The Exercise Price of an ISO shall not be less than 100% of the Fair Market Value of a Share on the date of grant, and a higher percentage may be required by Section 3(b). The Exercise Price of a Nonstatutory Option shall not be less than 85% of the Fair Market Value of a Share on the date of grant, and a higher percentage may be required by Section 3(b). Subject to the preceding two sentences, the Exercise Price under any Option shall be determined by the Board of Directors at its sole discretion. The Exercise Price shall be payable in a form described in Section 7.

(d) Exercisability . Each Stock Option Agreement shall specify the date when all or any installment of the Option is to become exercisable. No Option shall be exercisable unless the Optionee has delivered an executed copy of the Stock Option Agreement to the Company. In the case of an Optionee who is not an officer of the Company, an Outside Director or a Consultant, an Option shall become exercisable at least as rapidly as 20% per year over the five-year period commencing on the date of grant. Subject to the preceding sentence, the Board of Directors shall determine the exercisability provisions of the Stock Option Agreement at its sole discretion.

(e) Accelerated Exercisability . Unless the applicable Stock Option Agreement provides otherwise, all of an Optionee’s Options shall become exercisable in full if (i) the Company is subject to a Change in Control before the Optionee’s Service terminates, (ii) such Options do not remain outstanding, (iii) such Options are not assumed by the surviving corporation or its parent and (iv) the surviving corporation or its parent does not substitute options with substantially the same terms for such Options.
