(e) The following transactions shall be exempt from the provisions of this Section 4:

(i) any transfer of Shares to or for the benefit of any spouse, child or grandchild of the Participant, or to a trust for their benefit;

(f) The Company may assign its rights to purchase Offered Shares in any particular transaction under this Section 4 to one or more persons or entities.

- 3 -

(g) The provisions of this Section 4 shall terminate upon the earlier of the following events:

(i) the closing of the sale of shares of Common Stock in an underwritten public offering pursuant to an effective registration statement filed by the Company under the Securities Act; or

(ii) the sale of all or substantially all of the capital stock, assets or business of the Company, by merger, consolidation, sale of assets or otherwise (other than a merger or consolidation in which all or substantially all of the individuals and entities who were beneficial owners of the Common Stock immediately prior to such transaction beneficially own, directly or indirectly, more than 75% of the outstanding securities entitled to vote generally in the election of directors of the resulting, surviving or acquiring corporation in such transaction).

(h) The Company shall not be required (a) to transfer on its books any of the Shares which shall have been sold or transferred in violation of any of the provisions set forth in this Section 4, or (b) to treat as owner of such Shares or to pay dividends to any transferee to whom any such Shares shall have been so sold or transferred.

5. Agreement in Connection with Public Offering.

The Participant agrees, in connection with the initial underwritten public offering of the Company’s securities pursuant to a registration statement under the Securities Act, (i) not to sell, make short sale of, loan, grant any options for the purchase of, or otherwise dispose of any shares of Common Stock held by the Participant (other than those shares included in the offering) without the prior written consent of the Company or the underwriters managing such initial underwritten public offering of the Company’s securities for a period of 180 days from the effective date of such registration statement, and (ii) to execute any agreement reflecting clause (i) above as may be requested by the Company or the managing underwriters at the time of such offering.

The aggregate purchase price for the Shares shall be paid by the Participant by check payable to the order of the Company or such other method as may be acceptable to the Company. Upon receipt of payment by the Company for the Shares, the Company shall issue to the Participant one or more certificates in the name of the Participant for that number of Shares purchased by the Participant. The Participant agrees that the Shares shall be subject to the Purchase Option set forth in Section 2 of this Agreement and the restrictions on transfer set forth in Section 4 of this Agreement.

2. Purchase Option.

(a) In the event that the Participant ceases to be an employee, or officer or director of, or consultant or advisor to, the Company or any parent or subsidiary of the Company (an “Eligible Participant”) as defined in Section 424(e) or (f) of the Internal Revenue Code of 1986, as amended, and any regulations promulgated thereunder (the “Code”) for any reason or no reason, with or without cause, prior to , [final vesting date under option agreement], the Company shall have the right and option (the “Purchase Option”) to purchase from the Participant, for a sum equal to the Option Price per share, any shares then subject to the Purchase Option. All of the Shares shall be subject to the Purchase Option prior to , [the end of the first quarter following vesting commencement date]. thereafter, at the end of each quarter, one sixteenth (1/16) of such Shares shall no longer be subject to the Purchase Option until such time as all of such Shares are no longer subject to the Purchase Option.

(b) In the event that the Participant ceases to be an Eligible Participant by reason of death or permanent and total disability (within the meaning of Section 22(e)(3) of the Code), the Purchase Option shall lapse as to all of the Unvested Shares for which the Purchase Option would have otherwise become exercisable.

3. Exercise of Purchase Option and Closing.

(a) The Company may exercise the Purchase Option by delivering or mailing

to the Participant (or his estate), in accordance with Section 13, within 90 days after the Participant ceases to be an Eligible Participant, a written notice of exercise of the Purchase Option.

If and to the extent the Purchase Option is not so exercised by the giving of such a notice within such 90-day period, the Purchase Option shall automatically expire and terminate effective upon the expiration of such 90-day period.

(b) Within 10 days after the Participant’s receipt of the Company’s notice of the exercise of the Purchase Option pursuant to subsection (a) above, the Participant (or his estate or any escrow agent) shall tender to the Company at its principal offices the certificate or certificates representing the Shares which the Company has elected to purchase, duly endorsed in blank by the Participant or with duly endorsed stock powers attached thereto, all in form suitable for the transfer of such Shares to the Company.
