Service shall be subject to the Company Reacquisition Right (as defined in Section 4.1) immediately upon the termination of Grantee’s Service; and

(a) if Grantee is an employee at the time of Vesting, withhold, on behalf of Grantee, the Federal Insurance Contributions Act tax imposed
pursuant to Sections 3101 and 3121(v)(2) of the Code on the Vested Units (the “FICA Amount”). In addition, the Company shall pay Grantee an amount equal to the sum of (A) the FICA Amount, plus (B) a tax gross-up
payment (computed at the highest applicable marginal rate) in an amount that, after payment of all federal, state, and local income and employment taxes, results in the Grantee’s receipt and retention, on an after-tax basis, of an amount equal
to all federal, state, and local taxes payable by Grantee on the FICA Amount. 
 (b) if Grantee is a director or consultant at the time of
Vesting, pay Grantee an amount equal to the sum of (A) the taxes imposed pursuant to Section 1401 of the Code on the Vested Units that are treated as “self-employment income” (as defined in Section 1402(b) of the Code), plus
(B) a tax gross-up payment (computed at the highest applicable marginal rate) in an amount that, after payment of all federal, state, and local income and employment taxes, results in the Grantee’s receipt and retention, on an after-tax
basis, of an amount equal to all federal, state, and local taxes payable by Grantee on the amount specified in Section 3.5(b)(A). 
 The Company shall
make any payments due to Grantee pursuant to this Section 3.5 within 24 hours of the Vesting of any Units by wire transfer to the account designated by Grantee. 

3.6 Federal Excise Tax Under Section 4999 of the Code. 

(a) Excess Parachute Payment. If any acceleration of vesting pursuant to the Award and any other payment or benefit
(collectively, the “Payments”) received or to be received by the Grantee 

  
 4 

 
would, but for this Section, subject the Grantee to any excise tax pursuant to Section 4999 of the Code or any similar or successor provision (the “Excise
Tax”) due to the characterization of such acceleration of vesting, payment or benefit as an “excess parachute payment” under Section 280G of the Code, then the aggregate amount of the Payments will be either fully
payable or reduced to the largest portion of the Payments that would result in no portion of the Payments (after reduction) being subject to the Excise Tax, whichever results in the Grantee receiving the greatest amount of Payments, on an after-tax
basis (accounting for federal, state, and local income taxes and the Excise Tax), even if some or all of the Payments are subject to the Excise Tax. Any reduction in the Payments required by this Section will be made in the following order:
(i) reduction of cash payments; (ii) reduction of accelerated vesting of equity awards other than stock options; (iii) reduction of accelerated vesting of stock options; and (iv) reduction of other benefits paid or provided to
the Grantee. In the event that acceleration of vesting of equity awards is to be reduced, such acceleration of vesting will be cancelled in the reverse order of the date of grant of the Grantee’s equity awards. If two or more equity awards are
granted on the same date, each award will be reduced on a pro-rata basis. 
 (b) Determination by Tax Firm. No later than the
date of the occurrence of any event that might reasonably be anticipated to result in an “excess parachute payment” to the Grantee, the Company shall request a determination in writing by the professional firm engaged by the Company for
general tax purposes, or, if the tax firm so engaged by the Company is serving as accountant or auditor for the acquiror, the Company will appoint a nationally recognized tax firm to make the determinations required by this Section. (the
“Tax Firm”). As soon as practicable thereafter, the Tax Firm shall determine and report to the Company and the Grantee the amount of such acceleration of vesting, payments and benefits to be reduced, if any. For
the purposes of such determination, the Tax Firm may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and the Grantee shall furnish to the Tax Firm such information and
documents as the Tax Firm may reasonably request in order to make its required determination. The Company shall bear all fees and expenses the Tax Firm charge in connection with its services contemplated by this Section. 

4. COMPANY REACQUISITION RIGHT. 

4.1 Grant of Company Reacquisition Right. In the event that the Grantee’s Service terminates for any reason, the Grantee shall
forfeit and the Company shall automatically reacquire all Units for which the applicable Service Condition or Performance Condition has not been satisfied as of the time of such termination in accordance with Section 3 (the
“Unvested Units”), and the Grantee shall not be entitled to any payment therefor (the “Company Reacquisition Right”). 

4.2 Dividends, Distributions and Adjustments. Upon the occurrence of a dividend or distribution to the stockholders of
the Company paid in shares of Stock or other property, or any other adjustment upon a change in the capital structure of the Company as described in Section 7, any and all new, substituted or additional securities or other property to which the
Grantee is entitled by reason of the Grantee’s ownership of Unvested Units shall be immediately subject to the Company Reacquisition Right and included in the terms “Units” and “Unvested Units” for all purposes of the
Company Reacquisition Right with the same force and effect as the Unvested Units immediately prior to the dividend, distribution or adjustment, as the case may be. For purposes of determining the number of Units for which the applicable Service

from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance of any shares subject to this Agreement shall relieve the Company of any liability in respect of
the failure to issue such shares as to which such requisite authority shall not have been obtained. As a condition to the settlement of the Units, the Company may require the Grantee to satisfy any qualifications that may be necessary or
appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company.

“effected without receipt of consideration by the Company.” Any and all new, substituted or additional securities or other property (other than regular, periodic cash dividends paid on Stock pursuant to the Company’s dividend policy)
to which the Grantee is entitled by reason of ownership of Units acquired pursuant to this Agreement will be immediately subject to the provisions of this Agreement on the same basis as all Units originally acquired hereunder. Any fractional Unit or

 2.4 Termination of the Award. The Award shall terminate upon the first to occur of (a) the final
settlement of all Vested Units in accordance with Section 5 (including a final settlement upon the termination or cessation of Grantee’s Services) or (b) the Expiration Date if settlement has not occurred on or before the Expiration
Date. 
  

	 	3.	VESTING OF UNITS. 

3.1 Satisfaction of Service Condition. Except as provided by Section 3.2 below and subject to the Grantee’s continuous
Service through the applicable date set forth in the table below, the Service Condition will be satisfied in accordance with the following schedule: 
  

			
	 Service Date
	  	Percentage of Units
	 March 15, 2014
	  	25%
	 March 15, 2015
	  	25%
	 March 15, 2016
	  	50%

 3.2 Vesting Upon Change in Control or upon Termination Without Cause or Due to Death, Complete Disability
or Good Reason. Upon the Occurrence of a Change in Control, the Service Condition will be satisfied with respect to one-hundred percent (100%) of the Total Number of Units effective as of the date of such Change in Control. If the
Grantee’s Service is involuntarily terminated by the Company for any reason other than Cause or the Grantee’s Service terminates as a result of the Grantee’s death or Complete Disability or Grantee terminates his Service for Good
Reason, then the Service Condition will be satisfied with respect to one-hundred percent (100%) of the Total Number of Units effective as of the date of 

  
 3 

 
such termination of Service. If the Grantee voluntarily terminates his Service without Good Reason, there shall be no acceleration of the Service Condition. 

3.3 Effect of Termination of Service. Subject to the vesting provisions in Sections 3.1 and 3.2 above, upon the termination of
Grantee’s Service (whether by the Company or by Grantee and whether for Cause or for any or no reason), then: 
 (i) all Units for
which the Service Condition has not been satisfied as of the date of such termination of Service shall be subject to the Company Reacquisition Right (as defined in Section 4.1) immediately upon the termination of Grantee’s Service;
and 
 (ii) all Units for which the Service Condition has been satisfied as of the date of such termination of Service (including as
a result of Section 3.2) shall not be subject to the Company Reacquisition Right, but instead shall remain Vested Units. 
 3.4
Payments Upon Vesting. Upon the Vesting of any Units pursuant to Section 3.1 or 3.2 above, the Company shall: 
 (i) if Grantee
is an employee at the time of Vesting, withhold, on behalf of Grantee, the Federal Insurance Contributions Act tax imposed pursuant to Sections 3101 and 3121(v)(2) of the Code on the Vested Units (the “FICA Amount”). In
addition, the Company shall pay Grantee an amount equal to the sum of (A) the FICA Amount, plus (B) a tax gross-up payment (computed at the highest applicable marginal rate) in an amount that, after payment of all federal, state, and local
income and employment taxes, results in the Grantee’s receipt and retention, on an after-tax basis, of an amount equal to all federal, state, and local taxes payable by Grantee on the FICA Amount. 

(ii) if Grantee is a director or consultant at the time of Vesting, pay Grantee an amount equal to the sum of (A) the taxes imposed
pursuant to Section 1401 of the Code on the Vested Units that are treated as “self-employment income” (as defined in Section 1402(b) of the Code), plus (B) a tax gross-up payment (computed at the highest applicable marginal
rate) in an amount that, after payment of all federal, state, and local income and employment taxes, results in the Grantee’s receipt and retention, on an after-tax basis, of an amount equal to all federal, state, and local taxes payable by
Grantee on the amount specified in Section 3.4(ii)(A). 
 The Company shall make any payments due to Grantee pursuant to this Section 3.4 within
24 hours of the Vesting of any Units by wire transfer to the account designated by Grantee. 
 3.5 Federal Excise Tax Under
Section 4999 of the Code. 
 (a) Excess Parachute Payment. If any acceleration of vesting pursuant to the Award and
any other payment or benefit (collectively, the “Payments”) received or to be received by the Grantee would, but for this Section, subject the Grantee to any excise tax pursuant to Section 4999 of the Code
or any similar or successor provision (the “Excise Tax”) due to the characterization of such acceleration of vesting, payment or benefit as an “excess parachute payment” under Section 280G of the
Code, then the aggregate amount of the Payments will be either fully payable or reduced to the largest portion of the Payments that would result in no portion of the Payments (after reduction) being subject to the Excise Tax, whichever results in
the Grantee receiving the greatest amount of Payments, on an after-tax basis (accounting for federal, state, and local income taxes and the Excise Tax), even if some or all of the Payments are subject to the Excise Tax. Any reduction in the Payments
required by this Section will be made in the following order: (i) reduction of cash payments; (ii) reduction of accelerated vesting of equity awards other than stock options; (iii) reduction of accelerated vesting of stock options;
and (iv) reduction of other benefits paid or provided to the Grantee. In the event that acceleration of vesting of equity awards is to be reduced, such acceleration of vesting will be cancelled in the reverse order of the date of grant of the
Grantee’s equity awards. If two or more equity awards are granted on the same date, each award will be reduced on a pro-rata basis. 

  
 4 

 (b) Determination by Tax Firm. No later than the date of the occurrence of any
event that might reasonably be anticipated to result in an “excess parachute payment” to the Grantee, the Company shall request a determination in writing by the professional firm engaged by the Company for general tax purposes, or, if the
tax firm so engaged by the Company is serving as accountant or auditor for the acquiror, the Company will appoint a nationally recognized tax firm to make the determinations required by this Section. (the “Tax
Firm”). As soon as practicable thereafter, the Tax Firm shall determine and report to the Company and the Grantee the amount of such acceleration of vesting, payments and benefits to be reduced, if any. For the purposes of such
determination, the Tax Firm may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and the Grantee shall furnish to the Tax Firm such information and documents as the Tax Firm
may reasonably request in order to make its required determination. The Company shall bear all fees and expenses the Tax Firm charge in connection with its services contemplated by this Section. 

 

	 	4.	COMPANY REACQUISITION RIGHT. 

4.1 Grant of Company Reacquisition Right. In the event that the Grantee’s Service terminates for any reason, the Grantee shall
forfeit and the Company shall automatically reacquire all Units for which the Service Condition has not been satisfied as of the time of such termination in accordance with Section 3 (the “Unvested Units”),
and the Grantee shall not be entitled to any payment therefor (the “Company Reacquisition Right”). 
 4.2
Dividends, Distributions and Adjustments. Upon the occurrence of a dividend or distribution to the stockholders of the Company paid in shares of Stock or other property, or any other adjustment upon a change in the capital
structure of the Company as described in Section 7, any and all new, substituted or additional securities or other property to which the Grantee is entitled by reason of the Grantee’s ownership of Unvested Units shall be immediately
subject to the Company Reacquisition Right and included in the terms “Units” and “Unvested Units” for all purposes of the Company Reacquisition Right with the same force and effect as the Unvested Units immediately prior to the
dividend, distribution or adjustment, as the case may be. For purposes of determining the number of Units for which the Service Condition has been satisfied following a dividend, distribution or adjustment, credited Service shall include all Service
with any corporation which is a Participating Company at the time the Service is rendered, whether or not such corporation is a Participating Company both before and after any such event.

respect to such securities. No shares of Stock may be issued hereunder if the issuance of such shares would constitute a violation of any applicable federal, state or foreign securities laws or other law or regulations or the requirements of any
stock exchange or market system upon which the Stock may then be listed. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the
lawful issuance of any shares subject to this Agreement shall relieve the Company of any liability in respect of the failure to issue such shares as to which such requisite authority shall not have been obtained. As a condition to the settlement of
the Units, the Company may require the Grantee to satisfy any qualifications that may be 

  
 5 

 
necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company.

a sale with respect to some or all of the shares being acquired upon settlement of Units. 
 6.3 Withholding in Shares. The Company
shall, upon request by the Grantee, allow Grantee to satisfy all or any portion of a Participating Company’s tax withholding obligations by having the Company deduct from the shares of Stock otherwise deliverable to the Grantee in settlement of
the Units a number of whole shares having a fair market value, as determined by the Company as of the date on which the tax withholding obligations arise, not in excess of the amount of such tax withholding obligations determined by the applicable
minimum statutory withholding rates.

shall be made in the number of Units subject to this Agreement and/or the number and kind of shares or other property to be issued in settlement of the Units, in order to prevent dilution or enlargement of the Grantee’s rights under this
Agreement. For purposes of the foregoing, conversion of any convertible securities of the Company shall not be treated as “effected without receipt of consideration by the Company.” Any and all new, substituted or additional securities or
other property (other than regular, periodic cash dividends paid on Stock pursuant to the Company’s dividend policy) to which the Grantee is entitled by reason of ownership of Units acquired pursuant to this Agreement will be immediately
subject to the provisions of this Agreement on the same basis as all Units originally acquired hereunder. Any fractional Unit or share resulting from an 

  
 6 

 
adjustment pursuant to this Section shall be rounded down to the nearest whole number. Such adjustments shall be determined by the Board, and its determination shall be final, binding and
conclusive.

following such separation from 

  
 7 

 
service. All such amounts that would, but for this Section, become payable prior to the Delayed Payment Date will be accumulated and paid on the Delayed Payment Date.

	 	12.	REPRESENTATIONS AND WARRANTIES OF GRANTEE. 

In connection with the acquisition of securities pursuant to this Agreement, the Grantee hereby agrees, represents and warrants as follows:

 12.1 Investment Intent. The Grantee is acquiring shares of Stock pursuant to this Agreement solely for the Grantee’s own
account for investment and not with a view to or for sale in connection with any distribution of the shares or any portion thereof and not with any present intention of selling, offering to sell or otherwise disposing of or distributing the shares
or any portion thereof in any transaction other than a transaction exempt from registration under the Securities Act. The Grantee further represents that the entire legal and beneficial interest of the shares is being acquired, and will be held, for
the account of the Grantee only and neither in whole nor in part for any other person. 
 12.2 Absence of Solicitation. The Grantee
was not presented with or solicited by any form of general solicitation or general advertising, including, but not limited to, any advertisement, article, notice, or 

  
 8 

 
other communication published in any newspaper, magazine, or similar media, or broadcast over television, radio or similar communications media, or presented at any seminar or meeting whose
attendees have been invited by any general solicitation or general advertising. 
 12.3 Capacity to Protect Interests. The Grantee
has either (a) a preexisting personal or business relationship with the Company or any of its officers, directors, or controlling persons, consisting of personal or business contacts of a nature and duration to enable the Grantee to be aware of
the character, business acumen and general business and financial circumstances of the person with whom such relationship exists, or (b) such knowledge and experience in financial and business matters (or has relied on the financial and
business knowledge and experience of the Grantee’s professional advisor who is unaffiliated with and who is not, directly or indirectly, compensated by the Company or any affiliate or selling agent of the Company) as to make the Grantee capable
of evaluating the merits and risks of the investment in shares acquired pursuant to this Agreement and to protect the Grantee’s own interests in the transaction, or (c) both such relationship and such knowledge and experience. 

12.4 Restricted Securities. The Grantee understands and acknowledges that: 

(a) The issuance to Grantee of shares pursuant to this Agreement has not been registered under the Securities Act, and the shares must be
held indefinitely unless a transfer of the shares is subsequently registered under the Securities Act or an exemption from such registration is available, and that the Company is under no obligation to register the shares; and 

(b) The Company will make a notation in its records of the aforementioned restrictions on transfer and legends. 

12.5 Disposition Under Rule 144. The Grantee understands that if the shares acquired pursuant to this Agreement are not registered
prior to the Company’s issuance of such shares, the share will be restricted securities within the meaning of Rule 144 promulgated under the Securities Act (“Rule 144”). In addition, Grantee understands that he is
an “affiliate” for purposes of Rule 144, and as such, remains subject to the “affiliate” restrictions set forth in Rule 144. As a result, Grantee understands and agrees that any future transfers of the Stock must be
conducted in compliance with Rule 144. 
 12.6 Reliance by Company. The Grantee understands that the shares acquired pursuant to this
Agreement have not been registered under the Securities Act or under applicable state securities laws by reason of specific exemptions therefrom, which exemptions may depend upon, among other things, the bona fide nature of the Grantee’s
representations as expressed herein. The Grantee understands that the Company is relying on the Grantee’s representations and warrants that the Company is entitled to rely on such representations and that such reliance is reasonable. 

 

	 	13.	MISCELLANEOUS PROVISIONS. 

 13.1
Termination or Amendment. The Board may terminate or amend this Agreement at any time; provided, however, no such termination or amendment may adversely affect the Grantee’s rights under this Agreement without the consent of the Grantee
unless such termination or amendment is necessary to comply with applicable law or government regulation, including, but not limited to, Section 409A of the Code. No amendment or addition to this Agreement shall be effective unless in writing.

 13.2 Nontransferability of Units. Prior to the issuance of shares of Stock on the applicable Settlement Date, neither this
Agreement nor any Units subject to this Agreement shall be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Grantee or the Grantee’s beneficiary,
except transfer by will or by the laws of descent and distribution. All rights with respect to this Agreement shall be exercisable during the Grantee’s lifetime only by the Grantee or the Grantee’s guardian or legal representative.
