1. Nature of the Option. The Option is intended to be an [Incentive/Nonstatutory] Option within the meaning of the Company's 2012 Equity Incentive Plan (the "Plan"). All capitalized terms used herein and not otherwise defined shall have the meanings ascribed thereto in the Plan, which provisions are incorporated into this Agreement by this reference. The Optionee confirms and acknowledges that the Optionee has received and reviewed a copy of the Plan.
2. Vesting and Exercise of Option. The Option shall vest and become exercisable during its term in accordance with the following provisions:

1. Vesting and Right of Exercise.

1. The Option shall vest and become exercisable with respect to [one-fourth of the Shares at the first anniversary of the Vesting Commencement Date (as set forth above) and as to one thirty-sixth of the remaining Shares subject to the Option at the end of each successive month thereafter until all of the Shares subject to the Option have vested], subject to the Optionee's continued employment or other association with the Company.
2. In the event of the Optionee's death, disability or other termination of employment or other association with the Company, the Option shall be exercisable in the manner and to the extent provided in Section 6.3 of the Plan.
3. No fraction of a Share shall be purchasable or deliverable upon exercise, but in the event any adjustment hereunder of the number of Shares covered by the Option shall cause such number to include a fraction of a Share, such number of Shares shall be adjusted to the nearest smaller whole number of Shares.

2. Method of Exercise. In order to exercise any portion of this Option which has vested, the Optionee shall notify the Company in writing of the election to exercise the Option and the number of Shares in respect of which the Option is being exercised, by executing and delivering the Notice of Exercise of Stock Option in the form attached hereto as Appendix I.

3. Restrictions on Exercise. This Option may only be exercised with respect any portion hereof which has vested in accordance with subsection (a) above. This Option may not be exercised if the issuance of the Shares upon such exercise or the method of payment of consideration for such Shares would constitute a violation of any applicable federal or state securities law or other law or regulation. Furthermore, the method and manner of payment of the Option Price will be subject to the rules under Part 221 of Title 12 of the Code of Federal Regulations as promulgated by the Federal Reserve Board if such rules apply to the Company at the date of exercise. As a condition to the exercise of this Option, the Company may require the Optionee to make any representation or warranty to the Company at the time of exercise of this Option as in the opinion of legal counsel for the Company may be required by any applicable law or regulation, including the execution and delivery of an appropriate representation statement.

3. Non-Transferability of Option. This Option may be exercised during the lifetime of the Optionee only by the Optionee and may not be transferred in any manner other than by will or by the laws of descent and distribution. The terms of this Option shall be binding upon the executors, administrators, heirs and successors of the Optionee.
4. Method of Payment. Payment of the aggregate Option Price shall be by any of the following, or a combination thereof, at the election of the Optionee:

1. cash;
2. check payable to the Company;
3. delivery to the Company of shares of Common Stock having a Market Value equal to the Option Price of the Shares to be purchased; or
4. surrender of the Option as to all or part of the Shares for which the Option is then exercisable in exchange for shares of Common Stock having an aggregate Market Value equal to the difference between (i) the aggregate Market Value of the surrendered portion of the Option and (ii) the aggregate Option Price for the surrendered portion of the Option.

If the Common Stock is traded on an established market, payment of the Option Price may also be made through and under the terms and conditions of any formal cashless exercise program authorized by the Company entailing the sale of Shares subject to the Option in a brokered transaction (other than to the Company).

5. Adjustment for Corporate Actions. If subsequent to the Grant Date the outstanding shares of Common Stock are increased, decreased, or exchanged for a different number or kind of shares or other securities, or if additional shares or new or different shares or other securities are distributed with respect to shares of Common Stock, as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, or other similar distribution with respect to such shares of Common Stock, an appropriate and proportionate adjustment will be made in (i) the number and kind of shares or other securities then subject to the Option and (ii) the exercise price for each share or other unit of any other securities then subject to the Option (without change in the aggregate Option Price as to which the Option remains exercisable).
6. Treatment of Option in a Corporate Transaction. In a Corporate Transaction, the Committee, in its sole and absolute discretion, may take any one or more of the following actions as to the Option:

1. Assumption and Substitution. Provide that the Option shall be assumed, or substantially equivalent rights shall be provided in substitution therefor, by the acquiring or succeeding entity (or an affiliate thereof).
2. Termination. Upon written notice to the Optionee, provide that the Option shall terminate immediately prior to the consummation of the Corporate Transaction unless exercised within a specified period following the date of such notice and that any portion of the Option not then exercisable will expire automatically upon consummation of the Corporate Transaction.
3. Acceleration of Vesting. Provide that the portion of the Option not already exercisable in full shall Accelerate with respect to all or a portion of the Shares for which the Option is not then exercisable prior to or upon the consummation of the Corporate Transaction
4. Cash Payment to Optionee. Provide for a cash payment, net of applicable tax withholdings, to be made to the Optionee equal to the excess, if any, of (A) the acquisition price times the number of Shares subject to the Option (to the extent the Option Price does not exceed the acquisition price) over (B) the aggregate Option Price for all such Shares subject to the Option, in exchange for the termination of the Option; provided, that if the acquisition price does not exceed the Option Price, the Committee may cancel the Option without the payment of any consideration therefor prior to or upon the Corporate Transaction. For this purpose, "acquisition price" means the amount of cash, and market value of any other consideration, received in payment for a share of Common Stock surrendered in a Corporate Transaction.
5. Conversion Upon Liquidation or Dissolution. Provide that, in connection with a liquidation or dissolution of the Company, the Option shall convert into the right to receive liquidation proceeds net of the Option Price and any applicable tax withholdings.
6. Any combination of the foregoing.

None of the foregoing shall apply, however, if specifically prohibited under applicable laws, or by the rules and regulations of any governing governmental agencies or national securities exchanges on which the Common Stock is listed. Nor shall any of the foregoing apply in the case of a Qualified Performance- Based Award except to the extent the foregoing would not interfere with the qualification of the grant of the Option under Section 162(m) of the Code.

7. Term of Option. This Option may not be exercised more than [ten (10)] years from the Grant Date set forth above, and may be exercised during such term only in accordance with the terms of this Agreement.
8. Not Employment Contract. Nothing in this Agreement shall confer upon the Optionee any right to continue in the employ of the Company or shall interfere with or restrict in any way the rights of the Company, which are hereby expressly reserved, to discharge the Optionee at any time for any reason whatsoever, with or without cause, subject to the provisions of applicable law.
9. Income Tax Withholding.

1. The Optionee authorizes the Company to withhold in accordance with applicable law from any compensation payable to him or her any taxes required to be withheld by federal, state or local laws as a result of the exercise of this Option.

2. Any adverse consequences incurred by an Optionee with respect to the use of shares of Common Stock to pay any part of the Option Price or of any tax in connection with the exercise of the Option, including, without limitation, any adverse tax consequences arising as a result of a disqualifying disposition within the meaning of Section 422 of the Code shall be the sole responsibility of the Optionee.

10. Community Property. Without prejudice to the actual rights of the spouses as between each other, for all purposes of this Agreement, the Optionee shall be treated as agent and attorney-in-fact for that interest held or claimed by the Optionee's spouse with respect to this Option and any Shares and the parties hereto shall act in all matters as if the Optionee was the sole owner of this Option and (following exercise) any such Shares. This appointment is coupled with an interest and is irrevocable.
11. Miscellaneous.
