Capitalized terms used and not defined in this Agreement will have the meaning set forth in the Plan.

The Stock Options granted under this Award Agreement are not intended to be Incentive Stock Options covered by Section 422 of the Code except to the extent the Notice of Grant expressly states that the Stock Options are intended to be Incentive Stock Options.

2. Incorporation of the 2012 Incentive Plan. The Stock Options have been granted pursuant to the provisions of the Company’s 2012 Equity Incentive Plan, and the terms and definitions of the 2012 Equity Incentive Plan are incorporated into this Award Agreement by reference and made a part of this Award Agreement. The Employee acknowledges receipt of a copy of the 2012 Equity Incentive Plan.

3. Purchase Price. The price per share to be paid by the Employee for the shares purchased pursuant to these Stock Options (the “Exercise Price”) shall be as specified in the Notice of Grant. This Exercise Price shall be an amount not less than the Fair Market Value of a share of Common Stock as of the Date of Grant (as defined in the Plan and specified in the Notice of Grant), or not less than 110% of the Fair Market Value of a share of Common Stock if the Stock Options are Incentive Stock Options and Employee is a 10-percent shareholder described in Section 5.3.2 of the 2012 Equity Incentive Plan).

4. Exercise Terms. The Stock Options shall become vested and exercisable in the amounts and at the time(s) described in vesting schedule set forth in the Notice of Grant. The Stock Options shall become vested and exercisable only if the Employee continues to be employed by the Company through the vesting dates set forth in the vesting schedule in Notice of Grant.

The Employee must exercise the Stock Options for at least 100 shares, or, if less the full number of shares shown as Purchasable Shares in the vesting schedule in the Notice of Grant as to which the Stock Options remain unexercised.

If the Stock Options are not exercised with respect to all or any part of the shares subject to the Stock Options prior to the expiration date specified in the Notice of Grant (which shall be no later than ten (10) years from the date of grant), the Stock Options shall expire and any shares with respect to which the Stock Options were not exercised shall no longer be Purchasable Shares subject to the Stock Options.

No Stock Options shall be transferable by an Employee other than by will or the laws of descent and distribution or, in the case of non-Incentive Stock Options, pursuant to a Qualified Domestic Relations Order or as otherwise permitted pursuant to Section 11.7 of the 2012 Equity Incentive Plan. During the lifetime of an Employee, the Stock Options shall be exercisable only by such Employee (or by such Employee’s guardian or legal representative, should one be appointed).

6. Notice of Exercise of Option. The Stock Options may be exercised by the Employee, or by the Employee’s administrators, executors or personal representatives, by a written notice signed by the Employee, or by such administrators, executors or personal representatives, and delivered or mailed to the Company to the attention of the President, Chief Executive Officer or such other officer as the President or Chief Executive Officer may designate. Any such notice shall:

(a) specify the number of shares of Common Stock which the Employee or the Employee’s administrators, executors or personal representatives, as the case may be, then elects to purchase hereunder,

(b) contain such information as may be reasonably required pursuant to Section 11 below, and

(c) be accompanied by (i) a certified or cashier’s check or, if acceptable to the Committee, a recourse note payable to the Company in payment of the total Exercise Price applicable to such shares as provided herein, (ii) shares of Common Stock owned by the Employee and duly endorsed or accompanied by stock transfer powers having a Fair Market Value equal to the total Exercise Price applicable to such shares purchased under this Agreement, (iii) shares otherwise issuable upon exercise of the Stock Options having a Fair Market Value

equal to the total Exercise Price applicable to such shares purchased under this Agreement or (iv) a certified or cashier’s check or, if acceptable to the Committee, a recourse note payable to the Company, accompanied by the number of shares of Common Stock whose Fair Market Value when added to the amount of the check or note equals the total Exercise Price applicable to the shares being purchased under this Agreement.

Upon receipt of any such notice and accompanying payment, and subject to the terms hereof, the Company agrees to issue to the Employee or the Employee’s administrators, executors or personal representatives, as the case may be, stock certificates for the number of shares specified in such notice registered in the name of the person exercising the Stock Options.

7. Tax Withholding. Whenever the Employee exercises any portion of the Stock Options, the Company shall notify the Employee of the amount of tax (if any) which must be withheld by the Company under all applicable federal, state and local tax laws. The Employee agrees to make arrangements with the Company with respect to each exercise of the Stock Options to (a) remit the required amount to the Company, (b) authorize the Company to withhold a portion of the shares of Common Stock otherwise issuable upon the exercise with a value equal to such tax, (c) authorize the deduction of such amounts from the Employee’s regular salary payments, or (d) otherwise satisfy the applicable tax withholding requirement in a manner satisfactory to the Company.

8. Issuance of Stock Certificates for Shares. The stock certificates for any shares of Common Stock issuable to the Employee upon exercise of the Stock Options shall be delivered to the Employee (or to the person to whom the rights of the Employee shall have passed by will or the laws of descent and distribution) as promptly after the date of exercise as is feasible, but not before the Employee has paid the option price for such shares and made arrangements for any tax withholding, as required by Section 7.

9. Termination of Employment.

(b) Except as specified in the Notice of Grant for the Stock Options attached hereto, in the event of a termination of the Employee’s employment that is either (i) for Cause or (ii) voluntarily initiated on the part of the Employee and without the written consent of the Company, the Stock Options, to the extent not previously exercised, shall terminate immediately and shall not thereafter be or become exercisable.

(c) Unless and to the extent otherwise provided in the Notice of Grant, in the event of the retirement of the Employee at the normal retirement date as prescribed from time to time by the Company, the Employee shall continue to have the right to exercise any Stock Options for shares which were Purchasable Shares under the vesting schedule in the Notice of Grant at the date of the Employee’s retirement at any time within ninety (90) days after the date of retirement.

If the Employee was an employee of the Company at the time of death, any unvested rights to acquire shares pursuant to the Stock Options shall immediately vest and the Stock Options may be so exercised to the extent of the number of shares that were Purchasable Shares under the vesting schedule in the Notice of Grant at the date of death. If the Employee’s employment terminated prior to his or her death, the Stock Options may be exercised only to the extent of the number of shares covered by the Stock Options which were Purchasable Shares under the vesting schedule in the Notice of Grant at the date of such termination.

The Employee acknowledges that the issuance of capital stock of the Company is subject to limitations imposed by federal and state law, and the Employee hereby agrees that the Company shall not be obligated to issue any shares of Common Stock upon an attempted exercise of this Stock Options that would cause the Company to violate law or any rule, regulation, order or consent decree of any regulatory authority (including without limitation the SEC) having jurisdiction over the affairs of the Company. The Employee agrees that he or she will provide the Company with such information as is reasonably requested by the Company or its counsel to determine whether the issuance of Common Stock complies with the provisions described by this Section 11.
