EXHIBIT A

GENERAL TERMS AND CONDITIONS

The terms and conditions of the award of shares of restricted common stock, $0.0001 par value per share, of the Company (the “Restricted Shares”) made to the Recipient, as set forth on the cover page of this Agreement, and subject to the terms and conditions set forth in the 2013 Stock Incentive Plan (the “Plan”) are as follows:

1. Issuance of Restricted Shares.

(a) The Restricted Shares are issued to the Recipient, effective as of the Agreement Date (as set forth on the Notice of Grant), in consideration of services rendered and to be rendered by the Recipient to the Company.

(b) The Restricted Shares will initially be issued by the Company in book entry form only, in the name of the Recipient. Following the vesting of any Restricted Shares pursuant to Section 2 below, the Company shall, if requested by the Recipient, issue and deliver to the Recipient a certificate representing the vested Restricted Shares. The Recipient agrees that the Restricted Shares shall be subject to the forfeiture provisions set forth in Section 3 of this Agreement and the restrictions on transfer set forth in Section 4 of this Agreement

2. Vesting Schedule. The Restricted Shares shall vest in accordance with Vesting Table set forth in the Notice of Grant (the “Vesting Table”). Any fractional number of Restricted Shares resulting from the application of the percentages in the Vesting Table shall be rounded down to the nearest whole number of Restricted Shares.

Notwithstanding the foregoing, upon the consummation of a Change in Control Event, the then remaining unvested Restricted Shares shall immediately become fully vested and free from all forfeiture restrictions. “Change In Control Event” is defined in Exhibit B.

3. Forfeiture of Unvested Restricted Shares Upon Termination.

In the event that the Recipient ceases to be employed by or provide services to the Company or such other entity the service providers of which are eligible to receive an award under the Plan (each such entity, a “Participating Entity”) for any reason or no reason, with or without cause, all of the Restricted Shares that are unvested as of the time of such termination shall be forfeited immediately and automatically to the Company, without the payment of any consideration to the Recipient, effective as of such termination. The Recipient shall have no further rights with respect to any Restricted Shares that are so forfeited. If the Recipient is employed by or providing services to a Participating Entity, any references in this Agreement to employment with or services to the Company shall instead be deemed to refer to employment with or services to such Participating Entity.

4. Restrictions on Transfer. The Recipient shall not sell, assign, transfer, pledge, hypothecate or otherwise encumber, by operation of law or otherwise (collectively “transfer”) any Restricted Shares, or any interest therein, until such Restricted Shares have vested, except that the Recipient may transfer such Restricted Shares to or for the benefit of any immediate family member, family trust or other entity established for the benefit of the Recipient and/or an immediate family member thereof if the Company would be eligible to use a Form S-8 under the Securities Act for the registration of the sale of the Restricted Shares to such proposed transferee, provided that the Company shall not be required to recognize any such permitted transfer until such time as such permitted transferee shall, as a condition to the transfer, deliver to the Company a written instrument in form and substance satisfactory to the Company confirming that such transferee shall be bound by all of the terms and conditions of this Agreement. The Company shall not be required to (i) transfer on its books any of the Restricted Shares which have been transferred in violation of any of the provisions of this Agreement or (ii) treat as owner of such Restricted Shares or to pay dividends to any transferee to whom such Restricted Shares have been transferred in violation of any of the provisions of this Agreement.

5. Restrictive Legends.

The book entry account reflecting the issuance of the Restricted Shares in the name of the Recipient shall bear a legend or other notation upon substantially the following terms:

“These shares of stock are subject to forfeiture provisions and restrictions on transfer set forth in a certain Restricted Stock Agreement between the corporation and the registered owner of these shares (or his or her predecessor in interest), and such Agreement is available for inspection without charge at the office of the Secretary of the corporation.”

6. Rights as a Shareholder.

Except as otherwise provided in this Agreement, for so long as the Recipient is the registered owner of the Restricted Shares, the Recipient shall have all rights as a shareholder with respect to the Restricted Shares, whether vested or unvested, including, without limitation, rights to vote the Restricted Shares and act in respect of the Restricted Shares at any meeting of shareholders; provided that the payment of dividends on unvested Restricted Shares shall be deferred until such time as the shares vest.

7. Tax Matters.

(a) Acknowledgments; Section 83(b) Election. The Recipient acknowledges that he or she is responsible for obtaining the advice of the Recipient’s own tax advisors with respect to the acquisition of the Restricted Shares and the Recipient is relying solely on such advisors and not on any statements or representations of the Company or any of its agents with respect to the tax consequences relating to the Restricted Shares. The Recipient understands that the Recipient (and not the Company) shall be responsible for the Recipient’s tax liability that may arise in connection with the acquisition, vesting and/or disposition of the Restricted Shares. The Recipient understands that it may be beneficial in many circumstances to elect to be taxed at the time the Restricted Shares are granted by the Company rather than when and as the Restricted Shares vest by filing an election under Section 83(b) of the Internal Revenue Code of

1986 (the “Code”) with the Internal Revenue Service within 30 days from the date of grant by the Company. In the event the Recipient chooses to make an election under Section 83(b) of the Code, the Recipient shall deliver a copy of such election to the Company within 2 days of filing the election with the Internal Revenue Service.

THE RECIPIENT ACKNOWLEDGES THAT IT IS SOLELY THE RECIPIENT’S RESPONSIBILITY AND NOT THE COMPANY’S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b) OF THE CODE, EVEN IF THE RECIPIENT REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE THIS FILING ON THE RECIPIENT’S BEHALF.

8. Miscellaneous.

(a) Authority of Board. In making any decisions or taking any actions with respect to the matters covered by this Agreement, the Company’s Board of Directors (the “Board”) or any one or more of the committees or subcommittees of the Board to which the Board delegates its powers in accordance with the terms of the Plan shall have all of the authority and discretion, and shall be subject to all of the protections, provided for in the Plan. All decisions and actions by the Board or any one or more of its committees or subcommittees to which its powers have been delegated with respect to this Agreement shall be made in its discretion and shall be final and binding on the Recipient.

(b) No Right to Continued Service. The Recipient acknowledges and agrees that, notwithstanding the fact that the vesting of the Restricted Shares is contingent upon his or her continued employment by or service to the Company, this Agreement does not constitute an express or implied promise of continued employment or service or confer upon the Recipient any rights with respect to continued employment by or service to the Company.

(c) Governing Law. This Agreement shall be construed, interpreted and enforced in accordance with the internal laws of the State of Delaware, without regard to any applicable conflicts of law provisions.

(d) Recipient’s Acknowledgments. The Recipient acknowledges that he or she has read this Agreement, has received and read the Plan, and understands the terms and conditions of this Agreement and the Plan.
