	 	4.	Total Number of Shares of Incentive Stock. 

 The number of shares of Incentive Stock
which (i) may be issued by the Corporation under this Plan pursuant to the exercise of Options granted hereunder and (ii) may be issued by the Corporation under this Plan pursuant to the exercise of Rights granted hereunder, shall not
exceed an aggregate of Thirty-One Million Eight Hundred Forty Six Thousand Three Hundred (31,846,300) shares, which amount may be increased only as provided in Section 9 hereof or by a resolution adopted by the Board of Directors and
approved by the 

  
 4 








 
stockholders holding at least a majority of the outstanding shares of capital stock of the Corporation entitled to vote thereon in accordance with the Corporation Law or Section 422 of the
Code within twelve (12) months after such adoption by the Board of Directors. Such shares of Incentive Stock may be issued out of the authorized and unissued or reacquired Common Stock of the Corporation. Any shares subject to an Option, Right
or portion thereof which expires or is terminated unexercised (unless by virtue of the exercise of an Option or Right granted in tandem therewith) as to such shares may again be subject to an Option or Right under this Plan. To the extent there
shall be any adjustment in the number of shares of Incentive Stock pursuant to the provisions of Section 9 hereof, the aforesaid aggregate number of shares which may be issued by the Corporation under this Plan shall be likewise adjusted. 

 

	 	5.	Grants and Awards. 

 (a) As soon as practicable after the Board of Directors determines
to award an Option or Right, the appropriate officer or officers of the Corporation shall give notice (written, electronic or oral) to such effect to each Eligible Person designated to be awarded an Option or Right, which notice shall be accompanied
by a copy or copies of the Stock Option Agreement or Restricted Stock Agreement (as applicable), if any, to be executed by such Eligible Person. The Board of Directors may delegate to the appropriate officer or officers of the Corporation the
authority to prepare, execute and deliver any Stock Option Agreement or Restricted Stock Agreement evidencing any Option or Right granted under this Plan; provided, however, that any such Stock Option Agreement or Restricted Stock
Agreement shall be consistent with the terms and conditions of this Plan. 
 (b) Upon receipt of the notice specified in Section 5(A)
hereof, an Eligible Person shall have an Option or Right (as the case may be). Such Eligible Person shall nonetheless become and be a Participant only after the due execution (by written or electronic means) and delivery by such Eligible Person and
the Corporation of a Stock Option Agreement or Restricted Stock Agreement (in such form and number as the officer or officers of the Corporation shall direct) by such date and time as shall be specified in such notice (unless waived by the
Corporation); provided, however, that the Board of Directors may determine in any instance that an Eligible Person shall become a Participant upon such Participant’s receipt of the notice specified in Section 5(A) hereof and
not require the execution and delivery of any Stock Option Agreement or Restricted Stock Agreement by any Eligible Person. 
 (c) For any
Option intended to qualify as an ISO, in whole or in part, (i) the Eligible Person shall then be an employee of the Corporation or a Parent or Subsidiary, as provided in the Code; (ii) the term during which such Option shall be in effect
shall not be greater than ten (10) years, except in the case of an Option granted to a Controlling Participant, in which case the term shall not be greater than five (5) years; (iii) the Exercise Price shall not be less than one
hundred percent (100%) of the Fair Market Value on the date that such Option is granted, except in the case of an Option granted to a Controlling Participant, in which case the Exercise Price shall not be less than one hundred ten percent
(110%) of the Fair Market Value on the date that such Option is granted; (iv) such Option shall be exercisable only by the Participant during his or her lifetime and shall be nontransferable by the Participant unless the Stock Option
Agreement permits such Option to be transferred by will or the laws of descent and distribution; and (v) such Option may be exercised up to ninety (90) days after the date of termination of


  
 5 








 
Participant’s employment (except for termination for cause or due to death), or for up to six (6) months if termination is due to Participant’s death. 

(d) The purchase price for each share of Restricted Stock, as determined by the Board of Directors, need not be the Fair Market Value thereof,
and may vary from one Participant to another. In addition, the terms and conditions on which shares of Restricted Stock may be purchased may vary from one Participant to another. In computing the purchase price of a share of Restricted Stock, the
Board of Directors may take into consideration, without limitation, the restrictions on transfer or other disposition imposed in the applicable Restricted Stock Agreement. 

(e) In the event that the Corporation or any Parent or Subsidiary assumes an option granted by another entity, which option is to be covered by
this Plan and upon the exercise of which shares of Incentive Stock are to be issued, the terms and conditions of such option shall remain unchanged (except the exercise price and the number and nature of shares issuable upon exercise thereof, which
shall be adjusted appropriately in accordance with the Code, and references to such other entity, which shall be deemed to refer to the Corporation). In the event that the Board of Directors elects to grant an Option or Right under this Plan to
replace an option or right granted by another entity (rather than assume such option or right), the holder of such option shall be eligible to receive such replacement Option or Right, which may be granted with a similarly-adjusted Exercise Price.

  

	 	6.	Exercise and Termination of Options and Rights. 

 (a) Unless the applicable Stock Option
Agreement provides otherwise, any Option granted pursuant to this Plan to any employee of the Corporation or any Parent or Subsidiary shall cease vesting upon the termination of such employee’s employment with such entity. An Option of a
Participant may be exercised during the period such Option is in effect and as set forth herein and in the Stock Option Agreement, and only if compliance with all applicable federal and state securities laws can be effected. An Option may be
exercised only by (i) the Participant’s completion, execution and delivery to the Corporation of a notice (written or electronic) of such Participant’s exercise of such Option and an “investment letter” (if required by the
Corporation) as supplied by the Corporation and (ii) the payment to the Corporation of the aggregate Exercise Price, in accordance with Section 6(C) hereof and the Stock Option Agreement, for the shares of Incentive Stock to be purchased
pursuant to such exercise (as shall be specified by such Participant in such notice). Except as otherwise specifically provided by a duly executed Stock Option Agreement or unless waived by the Board of Directors, an Option or any of the rights
thereunder may be exercised by such Participant only, and may not be transferred or assigned, voluntarily, involuntarily or by operation of law (including, without limitation, the laws of bankruptcy, intestacy, descent and distribution and
succession). 
 (b) A Right of a Participant may be exercised during the period such Right is in effect and as set forth herein and in the
Restricted Stock Agreement, and only if compliance with all applicable federal and state securities laws can be effected. A Right may be exercised only by the Participant’s completion, execution and delivery to the Corporation of a notice
(written or electronic) of such Participant’s exercise of such Right (if such exercise is not simultaneous with the execution of the applicable Restricted Stock Agreement) and an 

  
 6 








 
“investment letter” (in each case if required by the Corporation) as supplied by the Corporation. Except as otherwise specifically provided by a duly executed Restricted Stock Agreement
or unless waived by the Board of Directors, a Right or any of the rights thereunder may be exercised by such Participant only, and may not be transferred or assigned, voluntarily, involuntarily or by operation of law (including, without limitation,
the laws of bankruptcy, intestacy, descent and distribution and succession). 
 (c) Payment by each Participant for the shares of Incentive
Stock or Restricted Stock purchased hereunder upon the exercise of an Option or a Right shall be made in accordance with the terms of the applicable Stock Option Agreement or Restricted Stock Agreement executed by such Participant. 

(d) The Board of Directors at any time or from time to time may offer to buy out for a payment in cash or Incentive Stock all or a portion of
an outstanding Option held by a Participant, based on such terms and conditions as the Board of Directors shall establish and communicate to the Participant at the time that such offer is made. The Board of Directors may provide for the surrender of
all or any portion of an Option in satisfaction of specified obligations of a Participant, including tax withholding obligations. 
 (e) As a
condition to the exercise of any Option (for non-cash consideration), the Corporation shall have the right to require that the Participant (or the recipient of any shares of Incentive Stock or non-cash consideration) remit to the Corporation or any
Parent or Subsidiary an amount calculated by the Corporation to be sufficient to satisfy applicable federal, state, foreign or local withholding tax requirements prior to the delivery of any stock certificate evidencing shares of Incentive Stock or
other form of non-cash consideration; in lieu thereof, the Participant may satisfy applicable withholding tax requirements by electing to have the Corporation withhold from the Incentive Stock issuable upon exercise of an Option a number of whole
shares having a Fair Market Value (determined on the date that the amount of tax to be withheld is to be fixed) at least equal to the aggregate amount required to be withheld. Whenever any payments are to be made in cash, the Corporation shall be
entitled, in its sole discretion, to deduct from such payment such amount calculated by the Corporation to be sufficient to satisfy applicable federal, state, foreign or local withholding tax requirements thereon. 

 

	 	7.	Costs and Expenses. 

 All costs and expenses with respect to the adoption,
implementation, interpretation and administration of this Plan shall be borne by the Corporation; provided, however, that, except as otherwise specifically provided in this Plan or the applicable Stock Option Agreement or Restricted
Stock Agreement between the Corporation and a Participant, the Corporation shall not be obligated to pay any costs or expenses (including legal fees) incurred by any Participant in connection with any Stock Option Agreement, Restricted Stock
Agreement, this Plan or any Option, Right, Restricted Stock or Incentive Stock held by any Participant. 

  
 7 









	 	8.	No Prior Right of Award. 

 Nothing in this Plan shall be deemed to give any director,
officer or employee of, or advisor or consultant to, the Corporation or any Parent or Subsidiary, or such person’s legal representatives or assigns, or any other person or entity claiming under or through such person, any contract or other
right to participate in the benefits of this Plan. Nothing in this Plan shall be construed as constituting a commitment, guarantee, agreement or understanding of any kind or nature that the Corporation or any Parent or Subsidiary shall continue to
employ, retain or engage any person (whether or not a Participant). This Plan shall not affect in any way the right of the Corporation and any Parent or Subsidiary to terminate the employment or engagement of any person (whether or not a
Participant) at any time and for any reason whatsoever and to remove any person (whether or not a Participant) from any position as a director or officer. No change of a Participant’s duties as an employee of the Corporation or any Parent or
Subsidiary shall result in a modification of the terms of any rights of such Participant under this Plan or any Stock Option Agreement or Restricted Stock Agreement executed by such Participant. 

 

	 	9.	Changes in Capital Structure. 

 Subject to any required action by the stockholders of the
Corporation and the provisions of the Corporation Law, the number of shares of: 
 (i) Incentive Stock represented by the unexercised
portion of an Option or Right; and 
 (ii) Incentive Stock which has been authorized or reserved for issuance hereunder (whether such shares
are unissued, reacquired or subject to an Option or Right that expired, was cancelled, surrendered or terminated unexercised as to such shares), 
 as well
as the Exercise Price under the unexercised portion of an Option and the purchase price of a share of Restricted Stock represented by the unexercised portion of a Right, shall be proportionately adjusted for (a) each stock split, reverse split,
stock dividend, division, combination, recapitalization or reclassification of any of the shares of Common Stock of the Corporation and (b) each dividend declared by the Board of Directors and payable in shares of Common Stock of the
Corporation. 
  

	 	10.	Plan History; Amendment or Termination of Plan. 

 Except as otherwise provided herein or
as required by law, this Plan may be amended or terminated in whole or in part by the Board of Directors (in its sole discretion), but no such action shall adversely affect or alter any right or obligation with respect to any Option, Right, Stock
Option Agreement or Restricted Stock Agreement then in effect, except to the extent that any such action shall be required or desirable (in the opinion of the Corporation or its counsel) so that any Option intended to qualify as an ISO complies with
the Code or any rule or regulation promulgated or proposed thereunder. This Plan was originally adopted in 2005. The Plan subsequently was amended in 2009. Effective April 7 2016, the Plan is amended and restated, subject to approval by the
stockholders of the Corporation, such that it is effective for one (1) year from December 31, 2015 (such anniversary, the “Restatement Termination Date”). The Plan shall terminate on the Restatement Termination Date. 

  
 8 









	 	11.	Voting. 

 The Common Stock received upon the exercise of any Option or the purchase of
Restricted Stock shall have equal voting rights as other outstanding shares of Common Stock on all matters where such vote is permitted by applicable law. 
  

	 	12.	Burden and Benefit. 

 The terms and provisions of this Plan shall be binding upon, and
shall inure to the benefit of, each Participant and such Participant’s executors and administrators, estate, heirs and personal and legal representatives. 
  

	 	13.	Headings. 

 The headings and other captions contained in this Plan are for convenience of
reference only and shall not be used in interpreting, construing or enforcing any of the provisions of this Plan. 
  

	 	14.	Interpretation. 

 Notwithstanding any provision of this Plan or any provision of any
Stock Option Agreement evidencing an Option that is intended, in whole or in part, to qualify as an ISO, this Plan and each such Stock Option Agreement are intended to comply with all requirements for qualification under the Code and with any rule
or regulation promulgated or proposed thereunder, and shall be interpreted and construed in a manner which is consistent with this Plan and each such Stock Option Agreement being so qualified. 

 

	 	15.	Governing Law. 

 This Plan shall be governed by, and construed in accordance with, the
substantive laws of the State of Delaware (other than provisions thereof relating to conflicts of law and choice of law), except to the extent that such law is preempted by Federal law.
