Restricted Stock Unit Agreement

EXHIBIT A

GENERAL TERMS AND CONDITIONS

The terms and conditions of the award of the right to receive shares of common stock, $0.0001 par value per share, of the Company (the “Common Stock”) made to the Recipient (the “Restricted Stock Units”), as set forth on the cover page of this Agreement, are as follows. This Restricted Stock Unit Agreement shall be subject to, and shall incorporate the terms and conditions of the 2013 Stock Incentive Plan (the “Plan”) as if the Restricted Stock Units were granted pursuant thereto, provided that, to the extent that there is an inconsistency between the Plan and this Agreement, this Agreement shall prevail.

1. Issuance of Restricted Stock Units.

(a) The Restricted Stock Units are granted to the Recipient, effective as of the Agreement Date (as set forth on the Notice of Grant), in consideration of employment and other services rendered and to be rendered by the Recipient to the Company. Each Restricted Stock Unit represents the right to receive one share of Common Stock, subject to the terms and conditions set forth in the cover page of this Agreement, these terms and conditions and the Plan.

(b) The Recipient agrees that the Restricted Stock Units 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; Delivery. The Restricted Stock Units shall vest in accordance with Vesting Table set forth in the Notice of Grant (the “Vesting Table”). Any fractional number of Restricted Stock Units resulting from the application of the percentages in the Vesting Table shall be rounded down to the nearest whole number of Restricted Stock Units. For the avoidance of doubt, 41.6667% of the Restricted Stock Units are vested as of the Agreement Date.

Notwithstanding the foregoing, if within the one-year period following a Change in Control Event, the Recipient’s employment with the Company is terminated by the Company without Cause or by the Recipient for Good Reason, then all remaining unvested Restricted Stock Units shall become fully vested and free from all forfeiture restrictions as of the date of such termination. “Change In Control Event”, “Cause” and “Good Reason” are defined in Exhibit B.

The Common Stock represented by vested Restricted Stock Units shall be delivered to the Recipient upon the earliest to occur of: (i) October 30, 2016; (ii) 30 days following the death of the Recipient; (iii) 30 days following the Recipient becoming disabled within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended and the guidance issued thereunder (“Section 409A”); (iv) upon the closing of a “change in control event” within the meaning of Section 409A and (v) three days following the Recipient’s “separation from service” within the meaning of Section 409A; provided that, solely to the extent that the Common Stock

is delivered to the Recipient upon the Recipient’s separation from service, the shares of Common Stock shall not be delivered until the date that is six months plus one day following such separation from service to the extent required to avoid adverse taxation under Section 409A. Except as set forth in the preceding sentence, neither the Company nor the Recipient may accelerate or defer delivery of the Common Stock unless specifically permitted or required by Section 409A. When delivered, the Common Stock will initially be issued by the Company in book entry form only, in the name of the Recipient. Following such delivery, the Company shall, if requested by the Recipient, issue and deliver to the Recipient a certificate representing the vested Common Stock.

3. Forfeiture of Unvested Restricted Stock Units Upon Service Termination.

In the event that the Recipient ceases to be an employee of 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 Stock Units that are unvested as of the time of such service termination shall be forfeited immediately and automatically to the Company, without the payment of any consideration to the Recipient, effective as of such termination of service. The Recipient shall have no further rights with respect to any Restricted Stock Units that are so forfeited. If the Recipient is providing service to a Participating Entity, any references in this Agreement to service with the Company shall instead be deemed to refer to service with 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 Stock Units, or any interest therein, until such Restricted Stock Units have vested and the Common Stock represented by such Units has been delivered pursuant to Section 2 hereof.

5. Rights as a Shareholder.

The Recipient shall have no rights as a shareholder with respect to the Restricted Stock Units until the Common Stock represented by such Units is delivered to the Recipient, except that to the extent that any dividends are paid with respect to the Common Stock represented by such Restricted Stock Units, whether vested or unvested, prior to delivery of the Common Stock pursuant to Section 2 hereof, such dividends shall accrue for the benefit of the Recipient and shall be paid to the Recipient at the time that the Common Stock is delivered to the Recipient pursuant to Section 2 hereof.

6. Tax Matters.

(a) Acknowledgments; No 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 grant of the Restricted Stock Units 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 Stock Units. 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 Stock Units and the Common Stock represented thereby. The Recipient understands that no election under Section 83(b) of the Internal Revenue Code of 1986 (the “Code”) is available with respect to the Restricted Stock Units.

(b) Withholding. The Recipient acknowledges and agrees that the Company has the right to deduct from payments of any kind otherwise due to the Recipient the amount of any withholding taxes required to be withheld with respect to the actions contemplated by this Agreement in any manner permitted by the Plan.

7. Agreement in Connection with Initial Public Offering. The Recipient agrees, in connection with the initial underwritten public offering of the Common Stock pursuant to a registration statement under the Securities Act, (i) not to (a) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any other securities of the Company convertible into or exercisable or exchangeable for shares of Common Stock or (b) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of shares of Common Stock or other securities of the Company, whether any transaction described in clause (a) or (b) is to be settled by delivery of securities, in cash or otherwise, during the period beginning on the date of the filing of such registration statement with the Securities and Exchange Commission and ending 180 days after the date of the final prospectus relating to the offering (plus up to an additional 34 days to the extent requested by the managing underwriters for such offering in order to address Rule 2711(f) of the National Association of Securities Dealers, Inc. or any similar successor provision), 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 Company may impose stop-transfer instructions with respect to the shares of Common Stock or other securities subject to the foregoing restriction until the end of the “lock-up” period.

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 Stock Units is contingent upon his or her continued service with the Company, this Agreement does not constitute an express or implied promise of continued service or confer upon the Recipient any rights with respect to continued service by 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.
