Incentive Stock Option. An Option intended to meet the requirements of, and that qualifies for, favorable federal income tax treatment under, Section 422 of the Code, and is so designated.

To the extent required to comply with Code section 422, in no event shall any person be granted Incentive Stock Options to the extent that the Shares covered by such options (and any Incentive Stock Options granted under any other plans of the Company and its Subsidiaries) that may be exercised for the first time by such person in any calendar year have an aggregate Fair Market Value in excess of $100,000. For this purpose, the Fair Market Value of the Shares shall be determined as of the dates on which the Incentive Stock Options are granted. It is intended that the limitation on Incentive Stock Options provided in this subsection be the maximum limitation on options which may be considered Incentive Stock Options under the Code, and this subsection shall be construed and applied in accordance with Code section 422.

Non-Incentive Stock Option. The Option is not intended to be an “incentive stock option” within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”).

Limitations on Incentive Stock Options. Notwithstanding anything in this Agreement (or in any Award Agreement evidencing the grant of an Option hereunder) to the contrary, Incentive Stock Options shall be transferable only to the extent permitted by Section 422 of the Internal Revenue Code and the treasury regulations thereunder without affecting the Option’s qualification under [Section 422] as an Incentive Stock Option.

Incentive Stock Option; Disqualifying Disposition. Although this Option is intended to qualify as an incentive stock option under the Internal Revenue Code of 1986 (the “Code”), the Company makes no representation as to the tax treatment upon exercise of this Option or sale or other disposition of the shares covered by this Option, and the Holder is advised to consult a personal tax advisor. Upon a Disqualifying Disposition of shares received upon exercise of this Option, the Holder will forfeit the favorable income tax treatment otherwise available with respect to the exercise of this Option. A “Disqualifying Disposition” shall have the meaning specified in Section 421(b) of the Code; as of the date of grant of this Option a Disqualifying Disposition is any disposition (including any sale) of such shares before the later of # the second anniversary of the date of grant of this Option and # the first anniversary of the date on which the Holder acquired such shares by exercising this Option, provided that such holding period requirements terminate upon the death of the Holder. The Holder shall notify the Company in writing immediately upon making a Disqualifying Disposition of any shares of Common Stock received pursuant to the exercise of this Option, and shall provide the Company with any information that the Company shall request concerning any such Disqualifying Disposition.

Grant as Incentive Stock Option. This option is intended to qualify as an incentive stock option under Section 422 of the Internal Revenue Code of 1986, as amended, and the regulations thereunder (the “Code”).

Stock Incentive. A recommendation will be submitted to the board of directors of the Company to grant you options to acquire 33,360 shares of common stock, with a strike price equal to the fair market value of the Company’s common stock on the day of the grant. The stock options will be subject to the terms of the Company’s Amended and Restated 2008 Stock Incentive Plan (the “Equity Plan”) and a stock option grant document. Vesting will occur over a four-year period with a one-year cliff (25% vested after 12 months with 2.083% vesting at the end of each month thereafter). Notwithstanding the foregoing, in the event that the Company closes a Series C financing transaction or there is a Sale Event (as defined in the Equity Plan), then the one-year cliff vesting shall not apply, and you shall vest monthly in your award starting on the first full month following your date of hire. In addition, upon a Sale Event you shall immediately accelerate in your vesting such that 50% of your then unvested shares shall accelerate and vest as of the Sale Event.

OTHER PROVISIONS. The Stock Option Agreement authorized under the Plan shall contain such other provisions, including without limitation restrictions upon the exercise of the Option, as the Board of Directors of the Company shall deem advisable. Any Incentive Stock Option Agreement shall contain such limitations and restrictions upon the exercise of the Incentive Stock Options as shall be necessary in order that such Option will be an Incentive Stock Option as defined in Section 422A of the Internal Revenue Code of 1986, as amended.

Price. Except for the limitations on Incentive Stock Options set forth below, the price at which each Share covered by an Option may be purchased shall be determined in each case by the Administrator and set forth in the Award Agreement. In no event shall the Exercise Price for each Share covered by an Option be less than the Fair Market Value of the Stock on the date the Option is granted. Further, the Exercise Price for each Share covered by an Incentive Stock Option granted to an Employee who then owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or any parent or subsidiary corporation of the Company must be at least 110% of the Fair Market Value of the Stock subject to the Incentive Stock Option on the date the Option is granted.

Incentive Stock Options. Notwithstanding the foregoing and, subject to adjustment as provided in [Section 15], the maximum number of Shares that may be issued upon the exercise of Incentive Stock Options will equal the aggregate Share number stated in Section 3(a), plus, to the extent allowable under Section 422 of the Code and the Treasury Regulations promulgated thereunder, any Shares that become available for issuance under the Plan pursuant to Section 3(b).
