(a) Ten (10) years from the date of this Agreement;

(b) The expiration of three (3) calendar months from the date on which Optionee’s Continuous Status as an Employee or Consultant is terminated (except by reason of Optionee’s disability, or Optionee’s death);

(c) The expiration of one (1) year from the date on which Optionee’s Continuous Status as an Employee or Consultant is terminated by reason of Optionee’s disability or Optionee’s death; or

ARTICLE 3. REPRESENTATIONS OF OPTIONEE

In connection with the grant of the Option and the purchase of any Option Shares under the provisions of this Agreement, Optionee hereby represents and warrants to the Company as follows:

Section 3.1 In General. Optionee has either:

(a) a pre-existing business or personal relationship with the Company or one or more of its officers, directors or controlling persons, or

(b) by reason of Optionee’s business or financial experience (or the business or financial experience of Optionee’s professional advisors who are unaffiliated with and who are not compensated by the Company or any affiliate or selling agent of the Company, directly or indirectly), Optionee could be reasonably assumed to have the capacity to evaluate the merits and risks of an investment in the Company and the Option Shares and to protect Optionee’s own interests in connection with the acquisition of the Option Rights and the purchase of Option Shares.

Section 3.2 The Plan. Optionee has received a copy of the Plan and has read and understood the Plan.

Section 3.3 Investment Intent; Capacity to Protect Interests.

(a) Optionee will be acquiring the Option Rights hereunder and, upon exercise of such Option Rights, will be acquiring Option Shares, only for Optionee’s own account for investment and not with a view to or for sale in connection with any distribution of the Option Rights or Option Shares or any portion thereof.

(b) Optionee will only be acquiring such Option Rights or Option Shares without any present intention of selling, offering to sell or otherwise disposing of or distributing the Option Rights or Option Shares or any portion thereof in any transaction other than a transaction exempt from registration under the 1933 Act

(c) The entire legal and beneficial interest of the Option Rights and Option Shares being purchased are, and will be, held for Optionee’s account only, and neither in whole or in part for any other person.

Section 3.4 Resident. Optionee’s principal residence is as set forth beneath Optionee’s signature to this Agreement.

Section 3.5 Information Concerning Company.

(a) Prior to the date of this Agreement, Optionee has discussed the Company and its plans, operations and financial condition with the Company’s officers and has received all such information as Optionee has deemed necessary and appropriate to enable Optionee to evaluate the financial risk inherent in this Agreement and Optionee has received satisfactory and complete information concerning the business and financial condition of the Company in response to all inquiries in respect thereof.

Page 3 of 9

(b) Prior to the exercise of any Option Rights hereunder, Optionee will have discussed the Company and its plans, operations and financial condition with the Company’s officers and will have received all such information as Optionee deems necessary and appropriate to enable Optionee to evaluate the financial risk inherent in making an investment in the Option Shares, and Optionee will have received satisfactory and complete information concerning the business and financial condition of the Company in response to all inquiries in respect thereof.

Section 3.6 Economic Risk. Optionee realizes that the purchase of Option Shares will be a highly speculative investment and involves a high degree of risk, and Optionee will not acquire any Option Shares unless Optionee is able, without impairing his or her financial condition, to hold the Option Shares for an indefinite period of time and to suffer a complete loss of Optionee’s investment.

Section 3.7 Restricted Securities. Optionee understands and acknowledges that:

(a) The sale of the Option Shares will not have been registered under the 1933 Act, and the Option Shares must be held indefinitely unless subsequently registered under the 1933 Act or an exemption from such registration is available (such as Rule 144 or the resale provisions of Rule 701 under the 1933 Act) and the Company is under no obligation to register the Option Shares;

(b) The share certificate(s) representing the Option Shares will be stamped with the legends specified in this Agreement or under applicable law; and

(c) The Company will make a notation in its records of the aforementioned restrictions on transfer and legends.

Section 3.8 Disposition under the 1933 Act. Optionee understands that the Option Shares will be restricted securities within the meaning of Rule 144 promulgated under the 1933 Act; that the exemption from registration under Rule 144 will not be available in any event for at least one (1) year from the date of purchase of the Option Shares (unless Rule 701 promulgated under the 1933 Act is available), and even then will not be available unless (a) a public trading market then exists for the Common Stock of the Company, (b) adequate information concerning the Company is then available to the public, and (c) other terms and conditions of Rule 144 are complied with; and that any sale of the Option Shares may be made only in limited amounts in accordance with such terms and conditions. Optionee further understands that the resale provisions of Rule 701, if available, will not apply until ninety (90) days after the Company becomes subject to the reporting obligations under the 1934 Act. There can be no assurance that the requirements of Rule 144 or Rule 701 will be met, or that the stock will ever be saleable.

Section 3.9 Further Limitations on Disposition. Without in any way limiting Optionee’s representations set forth above, Optionee further agrees that Optionee shall in no event make any disposition of all or any portion of the Option Shares unless and until:

(a) The Option Shares proposed to be transferred shall no longer be subject to the restrictions set forth in Articles 4, 5, 6 and 7 of this Agreement.

(b) One of the following conditions is satisfied:

(i) There is then in effect a Registration Statement under the 1933 Act covering such proposed disposition and such disposition is made in accordance with said Registration Statement.

(ii) The resale provisions of Rule 701 or Rule 144 are available in the opinion of counsel to the Company.

(iii) Optionee shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition; Optionee shall have furnished the Company with an opinion of Optionee’s counsel to the effect that such disposition will not require registration of such Option Shares under the 1933 Act; and such opinion of Optionee’s counsel shall have been concurred with by counsel for the Company and the Company shall have advised Optionee of such concurrence.

Section 3.10 Valuation of Common Stock. Optionee understands that the Board of Directors of the Company has, in good faith, attempted to set the option exercise price for the Option Shares at the fair market value of the

Page 4 of 9

Option Shares as of the date of the grant of the Option. Optionee understands, however, that the Company can give no assurances that such option exercise price is in fact the fair market value of the Option Shares as of the date of the grant of the Option (or as of any other date) and that it is possible that, with the benefit of hindsight, the Internal Revenue Service could successfully assert that the fair market value of the Option Shares on the date of the grant of the Option is in excess of the option exercise price. Such a determination could have adverse income tax consequence on Optionee consisting of, among other things:

(a) The loss of the benefits of treatment as “incentive stock options” under Section 422 of the Code.

(b) Upon exercise of the Option, the treatment of the difference between the fair market value of the Option Shares as of the date of exercise over the option exercise price as ordinary income of Optionee, resulting in the imposition of additional income taxes.

(c) The additional taxes (and interest) due would be payable by Optionee, and there is no provision for the Company to reimburse Optionee for that tax liability, and Optionee assumes all responsibility for such potential tax liability.

ARTICLE 4. MARKET STANDOFF

The provisions of this Article 4 shall be effective only after Optionee (or Optionee’s Representative) has exercised the Option in accordance with the provisions of this Agreement:

Section 4.1 Market Standoff. If so requested by the Company or any representative of the underwriters in connection with any registration of the offering of any securities of the Company under the 1933 Act, Optionee shall not sell or otherwise transfer any of the Restricted Shares or other securities of the Company during the 180-day period following the effective date of a registration statement of the Company filed under the 1933 Act; provided, however, that such restriction shall only apply to the first registration statement of the Company to become effective under the 1933 Act which includes securities to be sold on behalf of the Company to the public in an underwritten public offering (an “IPO”). The Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such 180-day period.

Section 4.2 Termination. The provisions of this Article 4 shall terminate upon the occurrence of a Major Transaction (other than an IPO, in which case, the provisions of this Article 4 shall survive the IPO for 180 days as provided above).

Page 5 of 9

(b) the aggregate fair market value of the Restricted Shares being repurchased as of the date of the termination of Optionee’s employment with or consultancy to the Company (or any Parent or Subsidiary of the Company).

Section  5.3 Closing.
