STOCKHOLDERS 

2.1    Place of Meetings. All meetings of stockholders shall be held at such place (if any) within or without the
State of Delaware as may be determined from time to time by the Board or, if not determined by the Board, by the Chairperson of the Board, the President or the Chief Executive Officer; provided that the Board may, in its sole discretion, determine
that any meeting of stockholders shall not be held at any place but shall be held solely by means of remote communication in accordance with Section 2.13. 

2.2    Annual Meeting. The annual meeting of stockholders for the election of directors and for the transaction of
such other business as may properly be brought before the meeting shall be held on a date to be fixed by the Board at a time to be fixed by the Board and stated in the notice of the meeting. 

2.3    Special Meetings. Subject to the Certificate of Incorporation, the rights of the holders of any series of
preferred stock then outstanding and to the requirements of applicable law, special meetings of the stockholders of the Corporation may be called only by the Board acting pursuant to a resolution adopted by a majority of the total number of
authorized directors (whether or not there exist any vacancies in previously authorized directorships at the time any such resolution is presented to the Board for adoption), the Chairperson of the Board, or the Chief Executive Officer and may not
be called by any other person or persons. Any business transacted at any special meeting of stockholders shall be limited to matters relating to the purpose or purposes stated in the notice of the meeting. 

2.4    Notice of Meetings. 

(a)    Written notice of each meeting of stockholders, whether annual or special, shall be given not less than 10 nor more
than 60 days before the date on which the meeting is to be held, to each stockholder entitled to vote at such meeting as of the record date fixed by the Board for determining the stockholders entitled to notice of the meeting, except as otherwise
provided herein or as required by law (meaning here and hereafter, as required from time to time by the Delaware General 

 
Corporation Law (the “DGCL”) or the Certificate of Incorporation. The notice of any meeting shall state the place, if any, date and hour of the meeting, and the means of
remote communication, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such meeting. The notice of a special meeting shall state, in addition, the purpose or purposes for which the meeting is called.

 (b)    Notice to stockholders shall be delivered in writing or in any other manner permitted by the DGCL. If mailed,
such notice shall be delivered by postage prepaid envelope directed to each stockholder at such stockholder’s address as it appears in the records of the Corporation and shall be deemed given when deposited in the United States mail. Notice
given by electronic transmission pursuant to this subsection shall be deemed given: (1) if by facsimile telecommunication, when directed to a facsimile telecommunication number at which the stockholder has consented to receive notice;
(2) if by electronic mail, when directed to an electronic mail address at which the stockholder has consented to receive notice; (3) if by posting on an electronic network together with separate notice to the stockholder of such specific
posting, upon the later of (A) such posting and (B) the giving of such separate notice; and (4) if by any other form of electronic transmission, when directed to the stockholder. An affidavit of the secretary or an assistant secretary
or of the transfer agent or other agent of the Corporation that the notice has been given by personal delivery, by mail, or by a form of electronic transmission shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

 (c)    Notice of any meeting of stockholders need not be given to any stockholder if waived by such stockholder
either in a writing signed by such stockholder or by electronic transmission, whether such waiver is given before or after such meeting is held. If such a waiver is given by electronic transmission, the electronic transmission must either set forth
or be submitted with information from which it can be determined that the electronic transmission was authorized by the stockholder. 

2.5    Voting List. The officer who has charge of the stock ledger of the Corporation shall prepare, at least 10
days before each meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting; the list shall reflect the stockholders entitled to vote as of the tenth day before the meeting date, arranged in alphabetical order for
each class of stock and showing the mailing address of each stockholder and the number of shares registered in the name of each stockholder. The Corporation shall not be required to include electronic mail addresses or other electronic contact
information on such list. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, for a period of at least 10 days prior to the meeting: (a) on a reasonably accessible electronic network, provided
that the information required to gain access to such list is provided with the notice of the meeting, (b) during ordinary business hours at the principal place of business of the Corporation or (c) in any other manner provided by law. If
the meeting is to be held at a place, the list shall be produced and kept at the time and place of the meeting during the whole time of the meeting, and may be examined by any stockholder who is present. If the meeting is to be held solely by means
of remote communication, such list shall also be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with
the notice of the meeting. The stock ledger shall be the only evidence as to the stockholders who are entitled to examine the list required by this Section 2.5 or to vote in person or by proxy at any meeting of stockholders. 

2.6    Quorum. Except as otherwise provided by law or these Bylaws, the holders of a majority of the shares of the
capital stock of the Corporation entitled to vote at the meeting, present in person or represented by proxy, shall constitute a quorum for the transaction of business. Where a separate class vote by a class or classes or series is required, a
majority of the shares of such class or classes or series present in person or represented by proxy shall constitute a quorum entitled to take action with respect to that vote on that matter. 

  
 2 

 2.7    Adjournments. Any meeting of stockholders may be adjourned
to any other time and to any other place at which a meeting of stockholders may be held under these Bylaws by the chairperson of the meeting or, in the absence of such person, by any officer entitled to preside at or to act as secretary of such
meeting, or by the holders of a majority of the shares of stock present or represented at the meeting and entitled to vote, although less than a quorum. When a meeting is adjourned to another place, date or time, written notice need not be given of
the adjourned meeting if the date, time and place, if any, thereof, and the means of remote communication, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such adjourned meeting, are announced at the
meeting at which the adjournment is taken; provided, however, that if the date of any adjourned meeting is more than 30 days after the date for which the meeting was originally noticed, or if the Board fixes a new record date for determining the
stockholders entitled to vote at the adjourned meeting in accordance with Section 5.5, written notice of the place, if any, date and time of the adjourned meeting and the means of remote communication, if any, by which stockholders and proxy
holders may be deemed to be present in person and vote at such adjourned meeting, shall be given in conformity herewith. At the adjourned meeting, the Corporation may transact any business which might have been transacted at the original meeting.

 2.8    Voting and Proxies. Each stockholder shall have one vote for each share of stock entitled to vote held
of record by such stockholder and a proportionate vote for each fractional share so held, unless otherwise provided by law or in the Certificate of Incorporation. Each stockholder of record entitled to vote at a meeting of stockholders may vote in
person or may authorize any other person or persons to vote or act for such stockholder by a written proxy executed by the stockholder or the stockholder’s authorized agent or by an electronic transmission permitted by law and delivered to the
Secretary of the Corporation. Any copy, facsimile transmission or other reliable reproduction of the writing or electronic transmission created pursuant to this section may be substituted or used in lieu of the original writing or electronic
transmission for any and all purposes for which the original writing or transmission could be used, provided that such copy, facsimile transmission or other reproduction shall be a complete reproduction of the entire original writing or electronic
transmission. 
 2.9    Action at Meeting. 

(a)    At any meeting of stockholders for the election of one or more directors at which a quorum is present, the election
shall be determined by a plurality of the votes cast by the stockholders entitled to vote at the election. 

(b)    All other matters shall be determined by a majority in voting power of the shares present in person or represented
by proxy and entitled to vote on the matter (or if there are two or more classes of stock entitled to vote as separate classes, then in the case of each such class, a majority of the shares of each such class present in person or represented by
proxy and entitled to vote on the matter shall decide such matter), provided that a quorum is present, except when a different vote is required by express provision of law, the Certificate of Incorporation or these Bylaws. 

(c)    All voting, including on the election of directors, but excepting where otherwise required by law, may be by a
voice vote; provided, that upon demand therefor by a stockholder entitled to vote or the stockholder’s proxy, a vote by ballot shall be taken. Each ballot shall state the name of the stockholder or proxy voting and such other information as may
be required under the procedure established for the meeting. The Corporation may, and to the extent required by law, shall, in advance of any meeting of stockholders, appoint one or more inspectors to act at the meeting and make a written report
thereof. The Corporation may designate one or more persons as an alternate inspector to 

  
 3 

 
replace any inspector who fails to act. If no inspector or alternate is able to act at a meeting of stockholders, the person presiding at the meeting may, and to the extent required by law,
shall, appoint one or more inspectors to act at the meeting. Each inspector, before entering upon the discharge of his duties, shall take and sign an oath to faithfully execute the duties of inspector with strict impartiality and according to the
best of his ability. 
 2.10    Stockholder Business (Other Than the Election of Directors). 

(a)    Only such business (other than nominations for election of directors, which is governed by Section 3.16 of
these Bylaws) shall be conducted as shall have been properly brought before an annual meeting. To be properly brought before an annual meeting, business must be either (i) specified in the notice of meeting (or any supplement thereto) given by
or at the direction of the Board, (ii) otherwise properly brought before the meeting by or at the direction of the Board, or (iii) otherwise properly brought before the meeting by a stockholder who (A) is a stockholder of record (and,
with respect to any beneficial owner, if different, on whose behalf such business is proposed, only if such beneficial owner is the beneficial owner of shares of the Corporation) both at the time of giving the notice provided for in this
Section 2.10 and at the time of the meeting, (B) is entitled to vote at the meeting and (C) has complied with the notice procedures set forth in this Section 2.10 as to such business. For any business to be properly brought
before an annual meeting by a stockholder (other than nominations for election of directors, which is governed by Section 3.16 of these Bylaws), it must be a proper matter for stockholder action under the DGCL, and the stockholder must have
given timely notice thereof in writing to the Secretary of the Corporation. To be timely, a stockholder’s notice shall be in writing and must be received at the Corporation’s principal executive offices not later than ninety (90) days
nor earlier than one hundred twenty (120) days prior to the first anniversary of the date of the preceding year’s annual meeting as first specified in the Corporation’s notice of meeting (without regard to any postponements or
adjournments of such meeting after such notice was first sent), provided, however, that if no annual meeting was held in the previous year or the date of the annual meeting is advanced by more than thirty (30) days, or delayed (other than as a
result of adjournment) by more than thirty (30) days from the anniversary of the previous year’s annual meeting, notice by the stockholder to be timely must be received not later than the close of business on the later of the ninetieth (90th) day prior to such annual meeting or the tenth (10th) day following the date on which public announcement of the date of such meeting is first
made. “Public announcement” for purposes hereof shall have the meaning set forth in Section 3.16(c) of these Bylaws. In no event shall the public announcement of an adjournment or postponement of an annual meeting
commence a new time period (or extend any time period) for the giving of a stockholder’s notice as described above. For business to be properly brought before a special meeting by a stockholder, the business must be limited to the purpose or
purposes set forth in a request under Section 2.3. 
 (b)    A stockholder’s notice to the Secretary of the
Corporation shall set forth (i) as to each matter the stockholder proposes to bring before the annual meeting, a brief description of the business desired to be brought before the annual meeting and the text of the proposal or business,
including the text of any resolutions proposed for consideration and in the event that such business includes a proposal to amend the Bylaws of the Corporation, the language of the proposed amendment, and (ii) as to the stockholder giving the
notice and the beneficial owner, if any, on whose behalf the proposal is being made, and any of their respective affiliates or associates (each within the meaning of Rule 12b-2 under the Securities Exchange
Act of 1934, as amended (the “Exchange Act”)) or others acting in concert therewith (each, a “Proposing Person”), (A) the name and address, as they appear on the Corporation’s books, of the
stockholder proposing such business and of any other Proposing Person, (B) the class or series and number of shares of the Corporation which are owned beneficially and of record by the stockholder and any other Proposing Person as of the date
of the notice, and a representation that the stockholder will notify the Corporation in writing within five (5) business days after the record 

  
 4 

 
date for voting at the meeting of the class or series and number of shares of the Corporation owned beneficially and of record by the stockholder and any other Proposing Person as of the record
date for voting at the meeting, (C) a representation that the stockholder intends to appear in person or by proxy at the meeting to propose the business specified in the notice, (D) any material interest of the stockholder and any other
Proposing Person in such business, (E) the following information regarding the ownership interests of the stockholder and any other Proposing Person which shall be supplemented in writing by the stockholder not later than ten (10) days
after the record date for voting at the meeting to disclose such interests as of such record date: (1) a description of any option, warrant, convertible security, stock appreciation right, or similar right with an exercise or conversion
privilege or a settlement payment or mechanism at a price related to any class or series of shares of the Corporation or with a value derived in whole or in part from the value of any class or series of shares of the Corporation, any derivative or
synthetic arrangement having the characteristics of a long position in any class or series of shares of the Corporation, or any contract, derivative, swap or other transaction or series of transactions designed to produce economic benefits and risks
that correspond substantially to the ownership of any class or series of shares of the Corporation, including due to the fact that the value of such contract, derivative, swap or other transaction or series of transactions is determined by reference
to the price, value or volatility of any class or series of shares of the Corporation, whether or not such instrument, contract or right shall be subject to settlement in the underlying class or series of shares of the Corporation, through the
delivery of cash or other property, or otherwise, and without regard to whether the stockholder of record or any other Proposing Person may have entered into transactions that hedge or mitigate the economic effect of such instrument, contract or
right (a “Derivative Instrument”) directly or indirectly owned beneficially by such stockholder or other Proposing Person, and any other direct or indirect opportunity to profit or share in any profit derived from any
increase or decrease in the value of shares of the Corporation; (2) a description of any proxy, contract, arrangement, understanding, or relationship pursuant to which such stockholder or other Proposing Person has a right to vote any shares of
any security of the Corporation; (3) a description of any agreement, arrangement, understanding, relationship or otherwise, including any repurchase or similar so-called “stock borrowing”
agreement or arrangement, engaged in, directly or indirectly, by such stockholder or other Proposing Person, the purpose or effect of which is to mitigate loss to, reduce the economic risk (of ownership or otherwise) of any class or series of the
shares of the Corporation by, manage the risk of share price changes for, or increase or decrease the voting power of, such stockholder or other Proposing Person with respect to any class or series of the shares of the Corporation, or which
provides, directly or indirectly, the opportunity to profit or share in any profit derived from any decrease in the price or value of any class or series of the shares of the Corporation (“Short Interests”); (4) a
description of any rights to dividends on the shares of the Corporation owned beneficially by such stockholder or other Proposing Person that are separated or separable from the underlying shares of the Corporation; (5) a description of any
proportionate interest in shares of the Corporation or Derivative Instruments held, directly or indirectly, by a general or limited partnership in which such stockholder or other Proposing Person is a general partner or, directly or indirectly,
beneficially owns an interest in a general partner; (6) a description of any performance-related fees (other than an asset-based fee) to which such stockholder or other Proposing Person is entitled based on any increase or decrease in the value
of shares of the Corporation or Derivative Instruments, if any, as of the date of such notice, including, without limitation, any such interests held by members of such stockholder’s or other Proposing Person’s immediate family sharing the
same household; (7) a description of any significant equity interests or any Derivative Instruments or Short Interests in any principal competitor of the Corporation held by such stockholder or other Proposing Person; and (8) a description
of any direct or indirect interest of such stockholder or other Proposing Person in any contract with the Corporation, any affiliate of the Corporation or any principal competitor of the Corporation (including, in any such case, any employment
agreement, collective bargaining agreement or consulting agreement), and (F) any other information relating to such stockholder or other Proposing Person, if any, that would be required to be disclosed in a proxy statement or other
filings required to be made in connection with solicitations of proxies for, as applicable, the proposal and/or for the election of directors in a contested election pursuant to Section 14 of the Exchange Act and the rules and regulations
promulgated thereunder. 

  
 5 

 (c)    Unless otherwise required by law, if the stockholder (or a
qualified representative of the stockholder) does not appear at the annual meeting of stockholders to present the proposed business, such proposed business shall not be transacted, notwithstanding that proxies in respect of such vote may have been
received by the Corporation. For purposes of this section, to be considered a qualified representative of the stockholder, a person must be a duly authorized officer, manager or partner of such stockholder or authorized by a writing executed by such
stockholder (or a reliable reproduction or electronic transmission of the writing) delivered to the Corporation prior to the making of such proposal at such meeting by such stockholder stating that such person is authorized to act for such
stockholder as proxy at the meeting of stockholders. 
 (d)    Notwithstanding the foregoing provisions of this
Section 2.10, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this Section 2.10; provided however, that any
references in this Section 2.10 to the Exchange Act or the rules and regulations promulgated thereunder are not intended to and shall not limit any requirements applicable to proposals as to any business to be considered pursuant to this
Section 2.10. Nothing in this Section 2.10 shall be deemed to affect any rights (i) of stockholders to request inclusion of proposals in the Corporation’s proxy statement pursuant to Rule
14a-8 under the Exchange Act or (ii) of the holders of any series of preferred stock if and to the extent provided for under law, the Certificate of Incorporation or these Bylaws. 

(e)    Notwithstanding any provisions to the contrary, the notice requirements set forth in subsections (a) and (b)
above shall be deemed satisfied by a stockholder if the stockholder has notified the Corporation of the stockholder’s intention to present a proposal at an annual meeting in compliance with applicable rules and regulations promulgated under the
Exchange Act and such stockholder’s proposal has been included in a proxy statement that has been prepared by the Corporation to solicit proxies for such annual meeting. 

2.11    Conduct of Business. At every meeting of the stockholders, the Chairperson of the Board, or, in his
absence, the Chief Executive Officer, or, in his absence, such other person as may be appointed by the Board, shall act as chairperson. The Secretary of the Corporation or a person designated by the chairperson of the meeting shall act as secretary
of the meeting. Unless otherwise approved by the chairperson of the meeting, attendance at the stockholders’ meeting is restricted to stockholders of record, persons authorized in accordance with Section 2.8 of these Bylaws to act by
proxy, and officers of the Corporation. 
 The chairperson of the meeting shall call the meeting to order, establish the agenda, and conduct
the business of the meeting in accordance therewith or, at the chairperson’s discretion, the business of the meeting may be conducted otherwise in accordance with the wishes of the stockholders in attendance. The date and time of the opening
and closing of the polls for each matter upon which the stockholders will vote at the meeting shall be announced at the meeting. 
 The
chairperson shall also conduct the meeting in an orderly manner, rule on the precedence of, and procedure on, motions and other procedural matters, and exercise discretion with respect to such procedural matters with fairness and good faith toward
all those entitled to take part. Without limiting the foregoing, the chairperson may (a) restrict attendance at any time to bona fide stockholders of record and their proxies and other persons in attendance at the invitation of the presiding
officer or Board, (b) restrict use of audio or video recording devices at the meeting, and (c) impose reasonable limits on the amount of time taken up at the meeting on discussion in general or on remarks by any one stockholder. Should any

  
 6 

 
person in attendance become unruly or obstruct the meeting proceedings, the chairperson shall have the power to have such person removed from the meeting. Notwithstanding anything in the Bylaws
to the contrary, no business shall be conducted at a meeting except in accordance with the procedures set forth in Section 2.10, this Section 2.11 and Section 3.16. The chairperson of the meeting, in addition to making any other
determinations that may be appropriate to the conduct of the meeting, shall have the power and duty to determine whether a nomination or any business proposed to be brought before the meeting was made or proposed, as the case may be, in accordance
with the provisions of Section 2.10, this Section 2.11 and Section 3.16, and if he should so determine that any proposed nomination or business is not in compliance with such sections, he shall so declare to the meeting that such
defective nomination or proposal shall be disregarded. 
 2.12    Stockholder Action Without Meeting. Any action
required or permitted to be taken by the stockholders of the Corporation must be effected at a duly called annual or special meeting of stockholders of the Corporation and may not be effected by any consent in writing by such stockholders; provided,
however, that any action required or permitted to be taken by the holders of preferred stock, voting separately as a series or separately as a class with one or more other such series, may be taken without a meeting, without prior notice and without
a vote, to the extent expressly so provided by the applicable certificate of designation relating to such series of preferred stock. 

2.13    Meetings by Remote Communication. If authorized by the Board, and subject to such guidelines and procedures
as the Board may adopt, stockholders and proxy holders not physically present at a meeting of stockholders may, by means of remote communication, participate in the meeting and be deemed present in person and vote at the meeting, whether such
meeting is to be held at a designated place or solely by means of remote communication, provided that (a) the Corporation shall implement reasonable measures to verify that each person deemed present and permitted to vote at the meeting by
means of remote communication is a stockholder or proxy holder, (b) the Corporation shall implement reasonable measures to provide such stockholders and proxy holders a reasonable opportunity to participate in the meeting and to vote on matters
submitted to the stockholders, including an opportunity to read or hear the proceedings of the meeting substantially concurrently with such proceedings, and (c) if any stockholder or proxy holder votes or takes other action at the meeting by
means of remote communication, a record of such vote or other action shall be maintained by the Corporation.

3.4    Resignations. Any director may resign at any time upon notice given in writing or by electronic transmission
to the Board, the Chairperson of the Board, the Chief Executive Officer of the Corporation or the Secretary. The resignation shall take effect at the time specified therein, and if no time is specified, at the time of its receipt. The acceptance of

3.6    Vacancies and Newly Created Directorships. Except as otherwise provided by applicable law, vacancies
occurring in any directorship (whether by death, resignation, retirement, disqualification, removal or other cause) and newly created directorships resulting from any increase in the number of directors shall be filled in accordance with the
Certificate of Incorporation. Any director elected to fill a vacancy or newly created directorship shall hold office until the next election of the class for which such director shall have been chosen and until his or her successor shall be duly
elected and qualified, or until his or her earlier death, resignation, retirement, disqualification or removal. 

3.7    Regular Meetings. Regular meetings of the Board may be held without notice at such time and place, either
within or without the State of Delaware, as shall be determined from time to time by the Board; provided that any director who is absent when such a determination is made shall be given notice of the determination. A regular meeting of the
Board may be held without notice immediately after and at the same place as the annual meeting of stockholders. 

3.8    Special Meetings. Special meetings of the Board may be called by the Chairperson of the Board, the Chief
Executive Officer, the President or a majority of the directors then in office and may be held at any time and place, within or without the State of Delaware.

message system at least 24 hours in advance of the meeting, (b) sending a facsimile to such director’s last known facsimile number, or delivering written notice by hand to such director’s last known business or home address, at least

3.12    Action at Meeting. At any meeting of the Board at which a quorum is present, the vote of a majority of
those present shall be sufficient to take any action, unless a different vote is specified by law, the Certificate of Incorporation or these Bylaws. 

3.13    Action by Written Consent. Any action required or permitted to be taken at any meeting of the Board or of
any committee of the Board may be taken without a meeting if all members of the Board or committee, as the case may be, consent to the action in writing or by electronic transmission, and the writings or electronic transmissions are filed with the
minutes of proceedings of the Board or committee. Such filing shall be in paper form if the minutes are maintained in paper form and shall be in electronic form if the minutes are maintained in electronic form. 

3.14    Committees. The Board may designate one or more committees, each committee to consist of one or more of the
directors of the Corporation, with such lawfully delegated powers and duties as it therefor confers; provided that, the committee membership of each committee designated by the Board will comply with the applicable rules of the exchange on
which any securities of the Corporation are listed. The Board may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. In the absence or
disqualification of a member of a committee, the member or members of the committee present at any meeting and not disqualified from voting, whether or not such member or members constitute a quorum, may unanimously appoint another member of the
Board to act at the meeting in the place of any such absent or disqualified member. Any such committee, to the extent provided in the resolution of the Board and subject to the provisions of the DGCL, shall have and may exercise all the powers and
authority of the Board in the management of the business and affairs of the Corporation and may authorize the seal of the Corporation to be affixed to all papers which may require it. Each such committee shall keep minutes and make such reports as
the Board may from time to time request. Except as the Board may otherwise determine, any committee may make rules for the conduct of its business, but unless otherwise provided by such rules, its business shall be conducted as nearly as possible in
the same manner as is provided in these Bylaws for the Board. Unless otherwise provided in the Certificate of Incorporation, these Bylaws or the resolutions of the Board designating the committee, a committee may create one or more subcommittees,
each subcommittee consists of one or more members of the committee, and delegate to a subcommittee any or all of the powers and authority of the committee. 

3.15    Compensation of Directors. Directors may be paid such compensation for their services and such
reimbursement for expenses of attendance at meetings as the Board may from time to time determine. No such payment shall preclude any director from serving the Corporation or any of its parent or subsidiary Corporations in any other capacity and
receiving compensation for such service. 
 3.16    Nomination of Director Candidates. 

(a)    Subject to the rights of holders of any class or series of preferred stock then outstanding, nominations for the
election of directors at an annual meeting may be made by (i) the Board or a duly authorized committee thereof or (ii) by any stockholder of the Corporation who is a stockholder of record at the time of giving the notice provided for in
paragraphs (b) and (c) of this Section 3.16, who is entitled to vote at the meeting and who complies with the procedures set forth in this Section 3.16.

(90) days nor earlier than one hundred twenty (120) days prior to the first anniversary of the date of the preceding year’s annual meeting as first specified in the Corporation’s notice of meeting (without regard to any
postponements or adjournments of such meeting after such notice was first sent), provided, however, that if no annual meeting was held in the previous year or the date of the annual meeting is advanced by more than thirty (30) days or delayed
(other than as a result of adjournment) by more than thirty (30) days from the first anniversary of the previous year’s annual meeting, notice by the stockholder to be timely must be received not later than the close of business on the
later of the ninetieth (90th) day prior to such annual meeting or the tenth (10th) day following the date on which public announcement of the

Person as of the record date for voting at the meeting, (iii) a representation that the stockholder intends to appear in person or by proxy at the meeting to nominate the nominee specified in the notice, (iv) the following information
regarding the ownership interests of the stockholder and any other Nominating Person, which shall be supplemented in writing by the stockholder not later than ten (10) days after the record date for notice of the meeting to disclose such
interests as of such record date: (A) a description of any Derivative Instrument directly or indirectly owned beneficially by such stockholder or other Nominating Person, and any other direct or indirect opportunity to profit or share in any
profit derived from any increase or decrease in the value of shares of the Corporation; (B) a description of any proxy, contract, arrangement, understanding, or relationship pursuant to which such stockholder or other Nominating Person has a
right to vote any shares of any security of the Corporation; (C) a description of any Short Interests in any securities of the Corporation directly or indirectly owned beneficially by such stockholder or other Nominating Person; (D) a
description of any rights to dividends on the shares of the Corporation owned beneficially by such stockholder or other Nominating Person that are separated or separable from the underlying shares of the Corporation; (E) a description of any
proportionate interest in shares of the Corporation or Derivative Instruments held, directly or indirectly, by a general or limited partnership in which such stockholder or other Nominating Person is a general partner or, directly or indirectly,
beneficially owns an interest in a general partner; (F) a description of any performance-related fees (other than an asset-based fee) to which such stockholder or other Nominating Person is entitled based on any increase or decrease in the

(naming such person or persons) pursuant to which the nomination or nominations are to be made by the stockholder, (vi) a description of all direct and indirect compensation and other
material monetary agreements, arrangements and understandings during the past three years, and any other material relationships, between or among such stockholder and any other Nominating Person, on the one hand, and each nominee, and his respective
affiliates and associates, or others acting in concert therewith, on the other hand, including, without limitation all information that would be required to be disclosed pursuant to Rule 404 promulgated under Regulation S-K if the stockholder and any Nominating Person, if any, or any affiliate or associate thereof or person acting in concert therewith, were the “registrant” for purposes of such rule and the nominee were a
director or executive officer of such registrant, (vii) such other information regarding each nominee as would be required to be included in a proxy statement filed pursuant to the proxy rules of the SEC, had the nominee been nominated, or
intended to be nominated, by the Board, and (viii) the signed consent of each nominee to serve as a director of the Corporation if so elected. In no event shall the public announcement of an adjournment or postponement of an annual meeting
commence a new time period (or extend any time period) for the giving of a stockholder’s notice as described above. Notwithstanding the second sentence of this Section 3.16(b), in the event that the number of directors to be elected at an
annual meeting is increased and there is no public announcement by the Corporation naming the nominees for the additional directorships at least 100 days prior to the one-year anniversary of the date of the
preceding year’s annual meeting as first specified in the Corporation’s notice of meeting (without regard to any postponements or adjournments of such meeting after such notice was first sent), a stockholder’s notice required by this
Section 3.16(b) shall also be considered timely, but only with respect to nominees for the additional directorships, if it shall be delivered to the Secretary at the principal executive offices of the Corporation not later than the close of
business on the 10th day following the day on which such public announcement is first made by the Corporation. 

(c)    Subject to the rights of holders of any class or series of preferred stock then outstanding, nominations of persons
for election to the Board may be made at a special meeting of stockholders at which directors are to be elected pursuant to the Corporation’s notice of meeting (i) by or at the direction of the Board or a committee thereof or (ii) by
any stockholder who complies with the notice procedures set forth in this Section 3.16 and who is a stockholder of record at the time such notice is delivered to the Secretary of the Corporation. In the event the Corporation calls a special
meeting of stockholders for the purpose of electing one or more directors to the Board, any such stockholder may nominate a person or persons (as the case may be), for election to such position(s) as are specified in the Corporation’s notice of
meeting, if the stockholder’s notice as required by Section 3.12(a) is delivered to the Secretary at the principal executive offices of the Corporation not earlier than ninety (90) days prior to such special meeting and not later than
the close of business on the later of the sixtieth (60th) day prior to such special meeting or the tenth (10th) day following the day on which
public announcement is first made of the date of the special meeting and of the nominees proposed by the Board to be elected at such meeting. In no event shall the public announcement of an adjournment or postponement of a special meeting commence a
new time period (or extend any time period) for the giving of a stockholder’s notice as described above. 

(d)    For purposes of these Bylaws, “public announcement” shall mean disclosure in a press
release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed or furnished by the Corporation with the SEC pursuant to Section 13, 14 or 15(d) of the Exchange Act. 

(e)    Only those persons who are nominated in accordance with the procedures set forth in this section shall be eligible
for election as directors at any meeting of stockholders. The Chairperson of the Board or Secretary may, if the facts warrant, determine that a notice received by the Corporation relating to a nomination proposed to be made does not satisfy the
requirements of this Section 3.16 (including if the stockholder does not provide the updated information required under Section 3.16(b) to 

  
 11 

 
the Corporation within five (5) business days following the record date for the meeting), and if it be so determined, shall so declare and any such nomination shall not be introduced at such
meeting of stockholders, notwithstanding that proxies in respect of such vote may have been received. The chairperson of the meeting shall have the power and duty to determine whether a nomination brought before the meeting was made in accordance
with the procedures set forth in this section, and, if any nomination is not in compliance with this section (including if the stockholder does not provide the updated information required under Section 3.16(b) to the Corporation within five
(5) business days following the record date for the meeting), to declare that such defective nomination shall be disregarded, notwithstanding that proxies in respect of such vote may have been received. Unless otherwise required by law, if the
stockholder (or a qualified representative of the stockholder) does not appear at the annual meeting or a special meeting of stockholders of the Corporation to present a nomination, such nomination shall be disregarded, notwithstanding that proxies
in respect of such vote may have been received by the Corporation. For purposes of this Section 3.16, to be considered a qualified representative of the stockholder, a person must be a duly authorized officer, manager or partner of such
stockholder or authorized by a writing executed by such stockholder (or a reliable reproduction or electronic transmission of the writing) delivered to the Corporation prior to the making of such nomination at such meeting by such stockholder
stating that such person is authorized to act for such stockholder as proxy at the meeting of stockholders. 

(f)    Notwithstanding the foregoing provisions of this Section 3.16, a stockholder shall also comply with all
applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this Section 3.16; provided however, that any references in this Section 3.16 to the Exchange Act or the rules
promulgated thereunder are not intended to and shall not limit any requirements applicable to nominations to be considered pursuant to this Section 3.16. Nothing in this Section 3.16 shall be deemed to affect any rights of the holders of
any series of preferred stock if and to the extent provided for under law, the Certificate of Incorporation or these Bylaws. 

3.17    Reliance on Books and Records. A member of the Board, or a member of any committee designated by the Board
shall, in the performance of such members’ duties, be fully protected in relying in good faith upon records of the Corporation and upon such information, opinions, reports or statements presented to the Corporation by any of the
Corporation’s officers or employees, or committees of the Board, or by any other person as to matters the member reasonably believes are within such other person’s professional or expert competence and who has been selected with reasonable
care by or on behalf of the Corporation.

part of any unissued balance of the authorized capital stock of the Corporation or the whole or any part of any unissued balance of the authorized capital stock of the Corporation held in its treasury may be issued, sold, transferred or otherwise
disposed of by vote of the Board in such manner, for such consideration and on such terms as the Board may determine. 

5.2    Stock Certificates. The shares of stock of the Corporation shall be represented by certificates, provided
that the Board may provide by resolution or resolutions that some or all of any class or series of stock of the Corporation shall be uncertificated shares; provided, however, that no such resolution shall apply to shares represented by a certificate
until such certificate is surrendered to the Corporation. Every holder of stock of the Corporation represented by certificates, and, upon written request to the Corporation’s transfer agent or registrar, any holder of uncertificated shares,
shall be entitled to have a certificate, in such form as may be prescribed by law and by the Board, certifying the number and class of shares of stock owned by such stockholder in the Corporation. Each such certificate shall be signed by, or in the
name of the Corporation by, the Chairperson or Vice Chairperson, if any, of the Board, or the President or a Vice President, and the Treasurer or an Assistant Treasurer, or the Secretary or an Assistant Secretary of the Corporation. Any or all of
the signatures on the certificate may be a facsimile. 
 Each certificate for shares of stock which are subject to any restriction on
transfer pursuant to the Certificate of Incorporation, the Bylaws, applicable securities laws or any agreement among any number of stockholders or among such holders and the Corporation shall have conspicuously noted on the face or back of the
certificate either the full text of the restriction or a statement of the existence of such restriction. 

  
 14 

 5.3    Transfers. Except as otherwise established by rules and
regulations adopted by the Board, and subject to applicable law, shares of stock may be transferred on the books of the Corporation: (i) in the case of shares represented by a certificate, by the surrender to the Corporation or its transfer
agent of the certificate representing such shares properly endorsed or accompanied by a written assignment or power of attorney properly executed, and with such proof of authority or authenticity of signature as the Corporation or its transfer agent
may reasonably require; and (ii) in the case of uncertificated shares, upon the receipt of proper transfer instructions from the registered owner thereof. Except as may be otherwise required by law, the Certificate of Incorporation or the
Bylaws, the Corporation shall be entitled to treat the record holder of stock as shown on its books as the owner of such stock for all purposes, including the payment of dividends and the right to vote with respect to such stock, regardless of any
transfer, pledge or other disposition of such stock until the shares have been transferred on the books of the Corporation in accordance with the requirements of these Bylaws. 

5.4    Lost, Stolen or Destroyed Certificates. The Corporation may issue a new certificate in place of any
previously issued certificate alleged to have been lost, stolen, or destroyed, or it may issue uncertificated shares if the shares represented by such certificate have been designated as uncertificated shares in accordance with Section 5.2,
upon such terms and conditions as the Board may prescribe, including the presentation of reasonable evidence of such loss, theft or destruction and the giving of such indemnity as the Board may require for the protection of the Corporation or any
transfer agent or registrar. 
 5.5    Record Dates. The Board may fix in advance a record date for the
determination of the stockholders entitled to vote at any meeting of stockholders. Such record date shall not precede the date on which the resolution fixing the record date is adopted and shall not be more than 60 nor less than 10 days before the
date of such meeting. 
 If no record date is fixed by the Board, the record date for determining the stockholders entitled to notice of or
to vote at a meeting of stockholders shall be the close of business on the day before the date on which notice is given, or, if notice is waived, the close of business on the day before the date on which the meeting is held. 

A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the
meeting; provided, however, that the Board may fix a new record date for the determination of stockholders entitled to vote at the adjourned meeting, and in such case shall also fix as the record date for stockholders entitled to notice of such
adjourned meeting the same or an earlier date as that fixed for the determination of stockholders entitled to vote in accordance with the foregoing provisions. 

The Board may fix in advance a record date (a) for the determination of stockholders entitled to receive payment of any dividend or other
distribution or allotment of any rights in respect of any change, concession or exchange of stock, or (b) for the purpose of any other lawful action. Any such record date shall not precede the date on which the resolution fixing the record date
is adopted and shall not be more than 60 days prior to the action to which such record date relates. If no record date is fixed by the Board, the record date for determining stockholders entitled to express consent to corporate action in writing
without a meeting when no prior action by the Board is necessary shall be the date on which the first written consent is expressed. The record date for determining stockholders for any other purpose shall be the close of business on the day on which
the Board adopts the resolution relating to such purpose.

Corporation may possess by reason of this Corporation’s ownership of securities in such other Corporation or other organization. 

6.4    Evidence of Authority. A certificate by the Secretary, or an Assistant Secretary, or a temporary Secretary,
as to any action taken by the stockholders, directors, a committee or any officer or representative of the Corporation shall as to all persons who rely on the certificate in good faith be conclusive evidence of such action.

deemed to refer to the Certificate of Incorporation of the Corporation, as amended and in effect from time to time.

 ARTICLE VIII 

INDEMNIFICATION OF DIRECTORS AND OFFICERS 

8.1    Right to Indemnification. Each person who was or is made a party or is threatened to be made a party to or
is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (“proceeding”), by reason of the fact that such person or a person of whom he or she is the

  
 17 

 
legal representative, is or was a director or officer of the Corporation or is or was serving at the request of the Corporation as a director or officer of another Corporation, or as a
controlling person of a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, whether the basis of such proceeding is alleged action in an official capacity as a director or officer, or in
any other capacity while serving as a director or officer, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended (but, in the case of any such
amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than such law permitted the Corporation to provide prior to such amendment) against all expenses, liability and loss reasonably
incurred or suffered by such person in connection therewith and such indemnification shall continue as to a person who has ceased to be a director or officer and shall inure to the benefit of his heirs, executors and administrators; provided, that
except as provided in Section 8.2 of this Article VIII, the Corporation shall indemnify any such person seeking indemnity in connection with a proceeding (or part thereof) initiated by such person only if (a) such indemnification is
expressly required to be made by law, (b) the proceeding (or part thereof) was authorized by the Board, (c) such indemnification is provided by the Corporation, in its sole discretion, pursuant to the powers vested in the Corporation under
the DGCL, or (d) the proceeding (or part thereof) is brought to establish or enforce a right to indemnification or advancement under an indemnity agreement or any other statute or law or otherwise as required under Section 145 of the DGCL.
The rights hereunder shall be contract rights and shall include the right to be paid reasonable expenses and attorneys’ fees incurred in defending any such proceeding in advance of its final disposition; provided, that the payment of such
expenses incurred by a director or officer of the Corporation in his capacity as a director or officer (and not in any other capacity in which service was or is tendered by such person while a director or officer, including, without limitation,
service to an employee benefit plan) in advance of the final disposition of such proceeding, shall be made only upon delivery to the Corporation of an undertaking, by or on behalf of such director or officer, to repay all amounts so advanced if it
should be determined ultimately by final judicial decision from which there is no further right to appeal that such director or officer is not entitled to be indemnified under this section or otherwise. 

8.2    Right of Claimant to Bring Suit. If a claim under Section 8.1 is not paid in full by the Corporation
within sixty (60) days after a written claim has been received by the Corporation, or twenty (20) days in the case of a claim for advancement of expenses, the claimant may at any time thereafter bring suit against the Corporation to
recover the unpaid amount of the claim and, if such suit is not frivolous or brought in bad faith, the claimant shall be entitled to be paid also the expense of prosecuting such claim. It shall be a defense to any such action (other than an action
brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the required undertaking, if any, has been tendered to this Corporation) that the claimant has not met the standards of conduct
which make it permissible under the DGCL for the Corporation to indemnify the claimant for the amount claimed. Neither the failure of the Corporation (including its Board, independent legal counsel, or its stockholders) to have made a determination
prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because the claimant has met the applicable standard of conduct set forth in the DGCL, nor an actual determination by the Corporation
(including its Board, independent legal counsel or its stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that claimant has not met the applicable standard of
conduct. In any suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such expenses upon a final judicial decision from which there is no further
right to appeal that the indemnitee has not met any applicable standard for indemnification set forth in the DGCL. In any suit brought by the indemnitee to enforce a right to indemnification or to an advancement of expenses hereunder, or brought by
the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the burden of proving that the indemnitee is not entitled to be indemnified, or to such advancement of expenses, shall be on the Corporation. 

  
 18 

 8.3    Indemnification of Employees and Agents. The Corporation
may, to the extent authorized from time to time by the Board, grant rights to indemnification, and to the advancement of related expenses, to any employee or agent of the Corporation to the fullest extent of the provisions of this Article VIII with
respect to the indemnification of and advancement of expenses to directors and officers of the Corporation. 

8.4    Non-Exclusivity of Rights. The rights conferred on any person in
this Article VIII shall not be exclusive of any other right which such persons may have or hereafter acquire under any statute, provision of the Certificate of Incorporation, Bylaw, agreement, vote of stockholders or disinterested directors or
otherwise. 
 8.5    Indemnification Contracts. The Board is authorized to enter into a contract with any
director, officer, employee or agent of the Corporation, or any person serving at the request of the Corporation as a director, officer, employee or agent of another Corporation, partnership, joint venture, trust or other enterprise, including
employee benefit plans, providing for indemnification rights equivalent to or, if the Board so determines, greater than, those provided for in this Article VIII. 

8.6    Insurance. The Corporation shall maintain insurance to the extent reasonably available, at its expense, to
protect itself and any such director, officer, employee or agent of the Corporation or another Corporation, partnership, joint venture, trust or other enterprise against any such expense, liability or loss, whether or not the Corporation would have
the power to indemnify such person against such expense, liability or loss under the DGCL. 
 8.7    Effect of
Amendment. Any amendment, repeal or modification of any provision of this Article VIII shall not adversely affect any right or protection of an indemnitee or his successor in respect of any act or omission occurring prior to such amendment,
repeal or modification. 
 8.8    Reliance. Persons who after the date of the adoption of this provision become
or remain directors or officers of the Corporation or who, while a director or officer of the Corporation, become or remain a director, officer, employee or agent of a subsidiary, shall be conclusively presumed to have relied on the rights to
indemnity, advance of expenses and other rights contained in this Article VIII in entering into or continuing such service. The rights to indemnification and to the advance of expenses conferred in this Article VIII shall apply to claims
made against an indemnitee arising out of acts or omissions which occurred or occur both prior and subsequent to the adoption hereof.

Board or the Company is delegated shall be indemnified by the Company against all reasonable expenses, including attorneys’ fees, actually and necessarily incurred in connection with the defense of any action, suit or proceeding, or in
connection with any appeal therein, to which they or any of them may be a party by reason of any action taken or failure to act under or in connection with the Plan, or any right granted hereunder, and against all amounts paid by them in settlement
thereof (provided such settlement is approved by independent legal counsel selected by the Company) or paid by them in satisfaction of a judgment in any such action, suit or proceeding, except in relation to matters as to which it shall be adjudged
in such action, suit or proceeding that such person is liable for gross negligence, bad faith or intentional misconduct in duties; provided, however, that within sixty (60) days after the institution of such action, suit or proceeding, such
person shall offer to the Company, in writing, the opportunity at its own expense to handle and defend the same. 
  

	 	4.	 SHARES SUBJECT TO PLAN.

 4.1 Maximum Number of Shares Issuable. Subject to adjustment as provided in Sections 4.3 and 4.4, the maximum
aggregate number of shares of Stock that may be issued under the Plan shall be 55,919,269 and shall consist of authorized but unissued or reacquired shares of Stock or any combination thereof. 

4.2 [INTENTIONALLY OMITTED] 

  
 8 

 4.3 Adjustments for Changes in Capital Structure. Subject to any
required action by the stockholders of the Company and the requirements of Sections 409A and 424 of the Code to the extent applicable, in the event of any change in the Stock effected without receipt of consideration by the Company, whether through
merger, consolidation, reorganization, reincorporation, recapitalization, reclassification, stock dividend, stock split, reverse stock split, split-up, split-off, spin-off, combination of shares, exchange of shares, or similar change in the capital
structure of the Company, or in the event of payment of a dividend or distribution to the stockholders of the Company in a form other than Stock (excepting regular, periodic cash dividends) that has a material effect on the Fair Market Value of
shares of Stock, appropriate and proportionate adjustments shall be made in the number and kind of shares subject to the Plan and to any outstanding Awards, in the ISO Share Limit set forth in Section 5.3(a), and in the exercise or purchase
price per share under any outstanding Awards in order to prevent dilution or enlargement of Participants’ rights under the Plan. 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.” If a majority of the shares which are of the same class as the shares that are subject to outstanding Awards are exchanged for, converted into, or otherwise become (whether or not
pursuant to an Ownership Change Event) shares of another corporation (the “New Shares”), the Board may unilaterally amend the outstanding Awards to provide that such Awards are for New Shares. In the event of any such amendment, the
number of shares subject to, and the exercise or purchase price per share of, the outstanding Awards shall be adjusted in a fair and equitable manner as determined by the Board, in its discretion. Any fractional share resulting from an adjustment
pursuant to this Section shall be rounded down to the nearest whole number, and the exercise or purchase price per share shall be rounded up to the nearest whole cent. In no event may the exercise or purchase price, if any, under any Award be
decreased to an amount less than the par value, if any, of the stock subject to the Award. Such adjustments shall be determined by the Board, and its determination shall be final, binding and conclusive. 

4.4 Assumption or Substitution of Awards. The Board may, without affecting the number of shares of Stock available pursuant to
Section 4.1, authorize the issuance or assumption of benefits under this Plan in connection with any merger, consolidation, acquisition of property or stock, or reorganization upon such terms and conditions as it may deem appropriate, subject
to compliance with Section 409A and any other applicable provisions of the Code. 
  

	 	5.	 ELIGIBILITY, PARTICIPATION AND OPTION
LIMITATIONS. 

 5.1 Persons Eligible for Awards. Awards may be granted only to
Employees, Consultants and Directors. 
 5.2 Participation in the Plan. Awards are granted solely at the discretion of the Board.
Eligible persons may be granted more than one Award. However, eligibility in accordance with this Section shall not entitle any person to be granted an Award, or, having been granted an Award, to be granted an additional Award. 

  
 9 

 5.3 Incentive Stock Option Limitations. 

(a) Maximum Number of Shares Issuable Pursuant to Incentive Stock Options. Subject to Section 4.1 and
adjustment as provided in Sections 4.3 and 4.4, the maximum aggregate number of shares of Stock that may be issued under the Plan pursuant to the exercise of Incentive Stock Options shall not exceed 55,919,269 shares (the “ISO
Share Limit”). The maximum aggregate number of shares of Stock that may be issued under the Plan pursuant to all Awards other than Incentive Stock Options shall be the number of shares determined in accordance with
Section 4.1, subject to adjustment as provided in Sections 4.3 and 4.4. 
 (b) Persons Eligible. An Incentive Stock
Option may be granted only to a person who, on the effective date of grant, is an Employee. Any person who is not an Employee on the effective date of the grant of an Option to such person may be granted only a Nonstatutory Stock Option. 

(c) Fair Market Value Limitation. To the extent that options designated as Incentive Stock Options (granted under all stock
plans of the Participating Company Group, including the Plan) become exercisable by a Participant for the first time during any calendar year for stock having a Fair Market Value greater than One Hundred Thousand Dollars ($100,000), the portion of
such options which exceeds such amount shall be treated as Nonstatutory Stock Options. For purposes of this Section, options designated as Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair
Market Value of stock shall be determined as of the time the option with respect to such stock is granted. If the Code is amended to provide for a limitation different from that set forth in this Section, such different limitation shall be deemed
incorporated herein effective as of the date and with respect to such Options as required or permitted by such amendment to the Code. If an Option is treated as an Incentive Stock Option in part and as a Nonstatutory Stock Option in part by reason
of the limitation set forth in this Section, the Participant may designate which portion of such Option the Participant is exercising. In the absence of such designation, the Participant shall be deemed to have exercised the Incentive Stock Option
portion of the Option first. Upon exercise of the Option, shares issued pursuant to each such portion shall be separately identified. 
  

	 	6.	 STOCK OPTIONS. 

Options shall be evidenced by Award Agreements specifying the number of shares of Stock covered thereby, in such form as the Board shall
establish. Such Award Agreements may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the following terms and conditions: 

6.1 Exercise Price. The exercise price for each Option shall be established in the discretion of the Board; provided,
however, that (a) the exercise price per share for an Option shall be not less than the Fair Market Value of a share of Stock on the effective date of grant of the Option and (b) no Incentive Stock Option granted to a Ten Percent
Stockholder shall have an exercise price per share less than one hundred ten percent (110%) of the Fair Market Value of a share of Stock on the effective date of grant of the Option. Notwithstanding the foregoing, an Option (whether an
Incentive Stock Option or a Nonstatutory Stock Option) may be granted with an exercise price lower than the minimum exercise price set forth above if such Option is granted pursuant to an assumption or substitution for another option in a manner
that would qualify under the provisions of Section 409A or Section 424(a) of the Code, as applicable. 

  
 10 

 6.2 Exercisability and Term of Options. Options shall be exercisable
at such time or times, or upon such event or events, and subject to such terms, conditions, performance criteria and restrictions as shall be determined by the Board and set forth in the Award Agreement evidencing such Option; provided, however,
that (a) no Option shall be exercisable after the expiration of ten (10) years after the effective date of grant of such Option, (b) no Incentive Stock Option granted to a Ten Percent Stockholder shall be exercisable after the
expiration of five (5) years after the effective date of grant of such Option, and (c) no Option granted to an Employee who is a non-exempt employee for purposes of the United States Fair Labor Standards Act of 1938, as amended, shall be
first exercisable until at least six (6) months following the date of grant of such Option (except in the event of such Employee’s death, disability or retirement, upon a Change in Control, or as otherwise permitted by the Worker Economic
Opportunity Act). Subject to the foregoing, unless otherwise specified by the Board in the grant of an Option, each Option shall terminate ten (10) years after the effective date of grant of the Option, unless earlier terminated in accordance
with its provisions. 
 6.3 Payment of Exercise Price. 

(a) Forms of Consideration Authorized. Except as otherwise provided below, payment of the exercise price for the number of
shares of Stock being purchased pursuant to any Option shall be made (i) in cash, by check or in cash equivalent, (ii) if permitted by the Company and subject to the limitations contained in Section 6.3(b), by means of (1) a
Stock Tender Exercise, (2) a Cashless Exercise or (3) a Net Exercise; (iii) by such other consideration as may be approved by the Board from time to time to the extent permitted by applicable law, or (iv) by any combination
thereof. The Board may at any time or from time to time grant Options which do not permit all of the foregoing forms of consideration to be used in payment of the exercise price or which otherwise restrict one or more forms of consideration. 

(b) Limitations on Forms of Consideration. 

(i) Stock Tender Exercise. A “Stock Tender Exercise” means the delivery of a properly executed
exercise notice accompanied by a Participant’s tender to the Company, or attestation to the ownership, in a form acceptable to the Company of whole shares of Stock having a Fair Market Value that does not exceed the aggregate exercise price for
the shares with respect to which the Option is exercised. A Stock Tender Exercise shall not be permitted if it would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock.
If required by the Company, an Option may not be exercised by tender to the Company, or attestation to the ownership, of shares of Stock unless such shares either have been owned by the Participant for a period of time required by the Company (and
not used for another option exercise by attestation during such period) or were not acquired, directly or indirectly, from the Company. 

(ii) Cashless Exercise. A Cashless Exercise shall be permitted only upon the class of shares subject to the Option becoming publicly
traded in an established securities market. A “Cashless Exercise” means the delivery of a properly executed exercise 

  
 11 

 
notice together with irrevocable instructions to a broker providing for the assignment to the Company of the proceeds of a sale or loan with respect to some or all of the shares being acquired
upon the exercise of the Option (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board of Governors of the United States Federal Reserve System). The Company
reserves, at any and all times, the right, in the Company’s sole and absolute discretion, to establish, decline to approve or terminate any program or procedures for the exercise of Options by means of a Cashless Exercise, including with
respect to one or more Participants specified by the Company notwithstanding that such program or procedures may be available to other Participants. 

(iii) Net Exercise. A “Net Exercise” means the delivery of a properly executed exercise notice
followed by a procedure pursuant to which (1) the Company will reduce the number of shares otherwise issuable to a Participant upon the exercise of an Option by the largest whole number of shares having a Fair Market Value that does not exceed
the aggregate exercise price for the shares with respect to which the Option is exercised, and (2) the Participant shall pay to the Company in cash the remaining balance of such aggregate exercise price not satisfied by such reduction in the
number of whole shares to be issued. 
 6.4 Effect of Termination of Service. 

(a) Option Exercisability. Subject to earlier termination of the Option as otherwise provided by this Plan and unless a
longer exercise period is provided by the Board, an Option shall terminate immediately upon the Participant’s termination of Service to the extent that it is then unvested and shall be exercisable after the Participant’s termination of
Service to the extent it is then vested only during the applicable time period determined in accordance with this Section and thereafter shall terminate: 

(i) Disability. If the Participant’s Service terminates because of the Disability of the Participant, the Option, to the extent
unexercised and exercisable for vested shares on the date on which the Participant’s Service terminated, may be exercised by the Participant (or the Participant’s guardian or legal representative) at any time prior to the expiration of
twelve (12) months (or such longer or shorter period provided by the Award Agreement) after the date on which the Participant’s Service terminated, but in any event no later than the date of expiration of the Option’s term as set
forth in the Award Agreement evidencing such Option (the “Option Expiration Date”). 
 (ii)
Death. If the Participant’s Service terminates because of the death of the Participant, the Option, to the extent unexercised and exercisable for vested shares on the date on which the Participant’s Service terminated, may be
exercised by the Participant’s legal representative or other person who acquired the right to exercise the Option by reason of the Participant’s death at any time prior to the expiration of twelve (12) months (or such longer or
shorter period provided by the Award Agreement) after the date on which the Participant’s Service terminated, but in any event no later than the Option Expiration Date. The Participant’s Service shall be deemed to have terminated on
account of death if the Participant dies within thirty (30) days (or such longer period provided by the Board) after the Participant’s termination of Service. 

  
 12 

 (iii) Termination for Cause. Notwithstanding any other provision of the Plan to the
contrary, if the Participant’s Service is terminated for Cause, the Option shall terminate in its entirety and cease to be exercisable immediately upon such termination of Service. 

(iv) Other Termination of Service. If the Participant’s Service terminates for any reason, except Disability, death or Cause, the
Option, to the extent unexercised and exercisable for vested shares on the date on which the Participant’s Service terminated, may be exercised by the Participant at any time prior to the expiration of three (3) months (or such longer or
shorter period provided by the Award Agreement) after the date on which the Participant’s Service terminated, but in any event no later than the Option Expiration Date. 

(b) Extension if Exercise Prevented by Law. Notwithstanding the foregoing other than termination of Service for Cause,
if the exercise of an Option within the applicable time periods set forth in Section 6.4(a) is prevented by the provisions of Section 12 below, the Option shall remain exercisable until the later of (i) thirty (30) days after the
date such exercise first would no longer be prevented by such provisions or (ii) the end of the applicable time period under Section 6.4(a), but in any event no later than the Option Expiration Date. 

6.5 Transferability of Options. During the lifetime of the Participant, an Option shall be exercisable only by the Participant or the
Participant’s guardian or legal representative. An Option shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Participant or the
Participant’s beneficiary, except transfer by will or by the laws of descent and distribution; provided, however, that to the extent permitted by the Board, in its discretion, and set forth in the Award Agreement evidencing such Option, an
Option shall be assignable or transferable subject to the applicable limitations, if any, described in Rule 701 under the Securities Act and the General Instructions to Form S-8 Registration Statement under the Securities Act or, in the case of an
Incentive Stock Option, only as permitted by applicable regulations under Section 421 of the Code in a manner that does not disqualify such Option as an Incentive Stock Option. Notwithstanding the foregoing, for so long as the Company is
relying on the exemption provided by Rule 12h-1(f) under the Exchange Act, no Option or, prior to its exercise, the shares to be issued upon the exercise of the Option, shall be transferred except in compliance with the restrictions on transfer
under Rule 12h-1(f) (including the requirement under such rule that any permitted transferee may not further transfer the Option) or be made subject to any short position, “put equivalent position” or “call equivalent position”
by the Participant, as such terms are defined in Rule 16a-1 of the Exchange Act. 
  

	 	7.	 RESTRICTED STOCK AWARDS. 

Restricted Stock Awards shall be evidenced by Award Agreements specifying whether the Award is a Restricted Stock Bonus or a Restricted Stock
Purchase Right and the number of shares of Stock subject to the Award, in such form as the Board shall establish. Such Award Agreements may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the
following terms and conditions: 
 7.1 Types of Restricted Stock Awards Authorized. Restricted Stock Awards may be granted in the
form of either a Restricted Stock Bonus or a Restricted Stock Purchase Right. Restricted Stock Awards may be granted upon such conditions as the Board shall determine, including, without limitation, upon the attainment of one or more performance
goals. 

  
 13 

 7.2 Purchase Price. The purchase price for shares of Stock issuable under each
Restricted Stock Purchase Right shall be established by the Board in its discretion. No monetary payment (other than applicable tax withholding) shall be required as a condition of receiving shares of Stock pursuant to a Restricted Stock Bonus, the
consideration for which shall be services actually rendered to a Participating Company or for its benefit. Notwithstanding the foregoing, if required by applicable state corporate law, the Participant shall furnish consideration in the form of cash
or past services rendered to a Participating Company or for its benefit having a value not less than the par value of the shares of Stock subject to a Restricted Stock Award. 

7.3 Purchase Period. A Restricted Stock Purchase Right shall be exercisable within a period established by the Board, which shall in
no event exceed thirty (30) days from the effective date of the grant of the Restricted Stock Purchase Right. 
 7.4 Payment of
Purchase Price. Except as otherwise provided below, payment of the purchase price for the number of shares of Stock being purchased pursuant to any Restricted Stock Purchase Right shall be made (a) in cash, by check or in cash equivalent,
(b) by such other consideration as may be approved by the Board from time to time to the extent permitted by applicable law, or (c) by any combination thereof. 

7.5 Vesting and Restrictions on Transfer. Shares issued pursuant to any Restricted Stock Award may (but need not) be made subject to
Vesting Conditions based upon the satisfaction of such Service requirements, conditions, restrictions or performance criteria, as shall be established by the Board and set forth in the Award Agreement evidencing such Award. During any period in
which shares acquired pursuant to a Restricted Stock Award remain subject to Vesting Conditions, such shares may not be sold, exchanged, transferred, pledged, assigned or otherwise disposed of other than pursuant to an Ownership Change Event or as
provided in Section 7.8. The Board, in its discretion, may provide in any Award Agreement evidencing a Restricted Stock Award that, if the satisfaction of Vesting Conditions with respect to any shares subject to such Restricted Stock Award
would otherwise occur on a day on which the sale of such shares would violate the provisions of the Trading Compliance Policy, then satisfaction of the Vesting Conditions automatically shall be determined on the next trading day on which the sale of
such shares would not violate the Trading Compliance Policy. Upon request by the Company, each Participant shall execute any agreement evidencing such transfer restrictions prior to the receipt of shares of Stock hereunder and shall promptly present
to the Company any and all certificates representing shares of Stock acquired hereunder for the placement on such certificates of appropriate legends evidencing any such transfer restrictions. 

7.6 Voting Rights; Dividends and Distributions. Except as provided in this Section, Section 7.5 and any Award Agreement, during
any period in which shares acquired pursuant to a Restricted Stock Award remain subject to Vesting Conditions, the Participant shall have all of the rights of a stockholder of the Company holding shares of Stock, including the

  
 14 

 
right to vote such shares and to receive all dividends and other distributions paid with respect to such shares; provided, however, that if so determined by the Board and provided by the Award
Agreement, such dividends and distributions shall be subject to the same Vesting Conditions as the shares subject to the Restricted Stock Award with respect to which such dividends or distributions were paid, and otherwise shall be paid no later
than the end of the calendar year in which such dividends or distributions are paid to stockholders (or, if later, the 15th day of the third month following the date such dividends or distributions are paid to stockholders). In the event of a
dividend or distribution paid in shares of Stock or other property or any other adjustment made upon a change in the capital structure of the Company as described in Section 4.3, any and all new, substituted or additional securities or other
property (other than regular, periodic cash dividends) to which the Participant is entitled by reason of the Participant’s Restricted Stock Award shall be immediately subject to the same Vesting Conditions as the shares subject to the
Restricted Stock Award with respect to which such dividends or distributions were paid or adjustments were made. 
 7.7 Effect of
Termination of Service. Unless otherwise provided by the Board in the Award Agreement evidencing a Restricted Stock Award, if a Participant’s Service terminates for any reason, whether voluntary or involuntary (including the
Participant’s death or disability), then (a) the Company shall have the option to repurchase for the purchase price paid by the Participant any shares acquired by the Participant pursuant to a Restricted Stock Purchase Right which remain
subject to Vesting Conditions as of the date of the Participant’s termination of Service and (b) the Participant shall forfeit to the Company any shares acquired by the Participant pursuant to a Restricted Stock Bonus which remain subject
to Vesting Conditions as of the date of the Participant’s termination of Service. The Company shall have the right to assign at any time any repurchase right it may have, whether or not such right is then exercisable, to one or more persons as
may be selected by the Company. 
 7.8 Nontransferability of Restricted Stock Award Rights. Rights to acquire shares of Stock
pursuant to a Restricted Stock Award shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance or garnishment by creditors of the Participant or the Participant’s beneficiary,
except transfer by will or the laws of descent and distribution. All rights with respect to a Restricted Stock Award granted to a Participant hereunder shall be exercisable during his or her lifetime only by such Participant or the
Participant’s guardian or legal representative. 
  

	 	8.	 RESTRICTED STOCK UNITS. 

Restricted Stock Unit Awards shall be evidenced by Award Agreements specifying the number of Restricted Stock Units subject to the Award, in
such form as the Board shall establish. Award Agreements evidencing Restricted Stock Units may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the following terms and conditions: 

8.1 Grant of Restricted Stock Unit Awards. Restricted Stock Unit Awards may be granted upon such conditions as the Board shall
determine, including, without limitation, upon the attainment of one or more performance goals established by the Board. 

  
 15 

 8.2 Purchase Price. No monetary payment (other than applicable tax withholding, if
any) shall be required as a condition of receiving a Restricted Stock Unit Award, the consideration for which shall be services actually rendered to a Participating Company or for its benefit. Notwithstanding the foregoing, if required by applicable
state corporate law, the Participant shall furnish consideration in the form of cash or past services rendered to a Participating Company or for its benefit having a value not less than the par value of the shares of Stock issued upon settlement of
the Restricted Stock Unit Award. 
 8.3 Vesting. Restricted Stock Unit Awards may (but need not) be made subject to Vesting
Conditions based upon the satisfaction of such Service requirements, conditions, restrictions or performance criteria as shall be established by the Board and set forth in the Award Agreement evidencing such Award. The Board, in its discretion, may
provide in any Award Agreement evidencing a Restricted Stock Unit Award that, if the satisfaction of Vesting Conditions with respect to any shares subject to the Award would otherwise occur on a day on which the sale of such shares would violate the
provisions of the Trading Compliance Policy, then the satisfaction of the Vesting Conditions automatically shall be determined on the first to occur of (a) the next trading day on which the sale of such shares would not violate the Trading
Compliance Policy or (b) the last day of the calendar year in which the original vesting date occurred. 
 8.4 Voting Rights,
Dividend Equivalent Rights and Distributions. Participants shall have no voting rights with respect to shares of Stock represented by Restricted Stock Units until the date of the issuance of such shares (as evidenced by the appropriate entry on
the books of the Company or of a duly authorized transfer agent of the Company). However, the Board, in its discretion, may provide in the Award Agreement evidencing any Restricted Stock Unit Award that the Participant shall be entitled to Dividend
Equivalent Rights with respect to the payment of cash dividends on Stock during the period beginning on the date such Award is granted and ending, with respect to each share subject to the Award, on the earlier of the date the Award is settled or
the date on which it is terminated. Dividend Equivalent Rights, if any, shall be paid by crediting the Participant with a cash amount or with additional whole Restricted Stock Units as of the date of payment of such cash dividends on Stock, as
determined by the Board. The number of additional Restricted Stock Units (rounded to the nearest whole number), if any, to be credited shall be determined by dividing (a) the amount of cash dividends paid on the dividend payment date with
respect to the number of shares of Stock represented by the Restricted Stock Units previously credited to the Participant by (b) the Fair Market Value per share of Stock on such date. Such cash amount or additional Restricted Stock Units shall
be subject to the same terms and conditions and shall be settled in the same manner and at the same time as the Restricted Stock Units originally subject to the Restricted Stock Unit Award. In the event of a dividend or distribution paid in shares
of Stock or other property or any other adjustment made upon a change in the capital structure of the Company as described in Section 4.3, appropriate adjustments shall be made in the Participant’s Restricted Stock Unit Award so that it
represents the right to receive upon settlement any and all new, substituted or additional securities or other property (other than regular, periodic cash dividends) to which the Participant would be entitled by reason of the shares of Stock
issuable upon settlement of the Award, and all such new, substituted or additional securities or other property shall be immediately subject to the same Vesting Conditions as are applicable to the Award. 

  
 16 

 8.5 Effect of Termination of Service. Unless otherwise provided by the Board and set
forth in the Award Agreement evidencing a Restricted Stock Unit Award, if a Participant’s Service terminates for any reason, whether voluntary or involuntary (including the Participant’s death or disability), then the Participant shall
forfeit to the Company any Restricted Stock Units pursuant to the Award which remain subject to Vesting Conditions as of the date of the Participant’s termination of Service. 

8.6 Settlement of Restricted Stock Unit Awards. The Company shall issue to a Participant on the date on which Restricted Stock Units
subject to the Participant’s Restricted Stock Unit Award vest or on such other date determined by the Board in compliance with Section 409A, if applicable, and set forth in the Award Agreement one (1) share of Stock (and/or any other
new, substituted or additional securities or other property pursuant to an adjustment described in Section 8.4) for each Restricted Stock Unit then becoming vested or otherwise to be settled on such date, subject to the withholding of
applicable taxes, if any. If permitted by the Board, the Participant may elect, consistent with the requirements of Section 409A, to defer receipt of all or any portion of the shares of Stock or other property otherwise issuable to the
Participant pursuant to this Section, and such deferred issuance date(s) and amount(s) elected by the Participant shall be set forth in the Award Agreement. Notwithstanding the foregoing, the Board, in its discretion, may provide for settlement of
any Restricted Stock Unit Award by payment to the Participant in cash of an amount equal to the Fair Market Value on the payment date of the shares of Stock or other property otherwise issuable to the Participant pursuant to this Section. 

8.7 Nontransferability of Restricted Stock Unit Awards. The right to receive shares pursuant to a Restricted Stock Unit Award shall
not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Participant or the Participant’s beneficiary, except transfer by will or by the laws of
descent and distribution. For so long as the Company is relying on an order of the United States Securities and Exchange Commission (the “SEC”) under Section 12(h) of the Exchange Act or a no-action
position of the Staff of the SEC relieving the Company from registration under Section 12(g) of the Exchange Act of the Units and the shares of Stock subject thereto, no Restricted Stock Unit Award, or prior to its settlement, shares of Stock
underlying such Award, shall be transferred except in compliance with the restrictions on transfer under Rule 12h-1(f) under the Exchange Act that would apply were the Restricted Stock Units subject to such rule (including the requirement under such
rule that any permitted transferee may not further transfer the securities) or be made subject to any short position, “put equivalent position” or “call equivalent position” by the Participant, as such terms are defined in Rule
16a-1 under the Exchange Act. All rights with respect to a Restricted Stock Unit Award granted to a Participant hereunder shall be exercisable during his or her lifetime only by such Participant or the Participant’s guardian or legal
representative. 
  

	 	9.	 STANDARD FORMS OF AWARD
AGREEMENTS. 

 9.1 Award Agreements. Each Award shall comply with and be subject
to the terms and conditions set forth in the appropriate form of Award Agreement approved by the Board and as amended from time to time. No Award or purported Award shall be a valid and binding obligation of the Company unless evidenced by a fully
executed Award Agreement, which execution may be evidenced by electronic means. 

  
 17 

 9.2 Authority to Vary Terms. The Board shall have the authority from
time to time to vary the terms of any standard form of Award Agreement either in connection with the grant or amendment of an individual Award or in connection with the authorization of a new standard form or forms; provided, however, that the terms
and conditions of any such new, revised or amended standard form or forms of Award Agreement are not inconsistent with the terms of the Plan. 
  

	 	10.	 CHANGE IN CONTROL. 

10.1 Effect of Change in Control on Awards. Subject to the requirements and limitations of Section 409A, if
applicable, the Board may provide for any one or more of the following: 
 (a) Accelerated Vesting. In its discretion, the
Board may provide in the grant of any Award or at any other time may take action it deems appropriate to provide for acceleration of the exercisability, vesting and/or settlement in connection with a Change in Control of each or any outstanding
Award or portion thereof and shares acquired pursuant thereto upon such conditions, including termination of the Participant’s Service prior to, upon, or following the Change in Control, and to such extent as the Board determines. 

(b) Assumption, Continuation or Substitution of Awards. In the event of a Change in Control, the surviving, continuing,
successor, or purchasing corporation or other business entity or parent thereof, as the case may be (the “Acquiror”), may, without the consent of any Participant, assume or continue the Company’s rights and
obligations under each or any Award or portion thereof outstanding immediately prior to the Change in Control or substitute for each or any such outstanding Award or portion thereof a substantially equivalent award with respect to the
Acquiror’s stock. For purposes of this Section, if so determined by the Board, in its discretion, an Award or any portion thereof shall be deemed assumed if, following the Change in Control, the Award confers the right to receive, subject to
the terms and conditions of the Plan and the applicable Award Agreement, for each share of Stock subject to such portion of the Award immediately prior to the Change in Control, the consideration (whether stock, cash, other securities or property or
a combination thereof) to which a holder of a share of Stock on the effective date of the Change in Control was entitled (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the
outstanding shares of Stock); provided, however, that if such consideration is not solely common stock of the Acquiror, the Board may, with the consent of the Acquiror, provide for the consideration to be received upon the exercise or settlement of
the Award, for each share of Stock subject to the Award, solely common stock of the Acquiror equal in Fair Market Value to the per share consideration received by holders of Stock pursuant to the Change in Control. If any portion of such
consideration may be received by holders of Stock pursuant to the Change in Control on a contingent or delayed basis, the Board may, in its discretion, determine such Fair Market Value per share as of the time of the Change in Control on the basis
of the Board’s good faith estimate of the present value of the probable future payment of such consideration. Any Award or portion thereof which is neither assumed or continued by the Acquiror in connection with the Change in

  
 18 

 
Control nor exercised as of the time of consummation of the Change in Control shall terminate and cease to be outstanding effective as of the time of consummation of the Change in Control.
Notwithstanding the foregoing, shares acquired upon exercise of an Award prior to the Change in Control and any consideration received pursuant to the Change in Control with respect to such shares shall continue to be subject to all applicable
provisions of the Award Agreement evidencing such Award except as otherwise provided in such Award Agreement. 
 (c) Cash-Out of
Outstanding Awards. The Board may, in its discretion and without the consent of any Participant, determine that, upon the occurrence of a Change in Control, each or any Award or portion thereof outstanding immediately prior to the Change in
Control and not previously exercised or settled shall be canceled in exchange for a payment with respect to each vested share (and each unvested share, if so determined by the Board) of Stock subject to such canceled Award in (i) cash,
(ii) stock of the Company or of a corporation or other business entity a party to the Change in Control, or (iii) other property which, in any such case, shall be in an amount having a Fair Market Value equal to the Fair Market Value of
the consideration to be paid per share of Stock in the Change in Control, reduced (but not below zero) by the exercise or purchase price per share, if any, under such Award. If any portion of such consideration may be received by holders of Stock
pursuant to the Change in Control on a contingent or delayed basis, the Board may, in its sole discretion, determine such Fair Market Value per share as of the time of the Change in Control on the basis of the Board’s good faith estimate of the
present value of the probable amount of future payment of such consideration. In the event such determination is made by the Board, an Award having an exercise or purchase price per share equal to or greater than the Fair Market Value of the
consideration to be paid per share of Stock in the Change in Control may be canceled without payment of consideration to the holder thereof. Payment pursuant to this Section (reduced by applicable withholding taxes, if any) shall be made to
Participants in respect of the vested portions of their canceled Awards as soon as practicable following the date of the Change in Control and in respect of the unvested portions of their canceled Awards in accordance with the vesting schedules
applicable to such Awards. 
 10.2 Federal Excise Tax Under Section 4999 of the Code. 

(a) Excess Parachute Payment. If any acceleration of vesting pursuant to an Award and any other payment or benefit received or
to be received by a Participant would subject the Participant to any excise tax pursuant to Section 4999 of the Code due to the characterization of such acceleration of vesting, payment or benefit as an “excess parachute payment”
under Section 280G of the Code, then, provided such election would not subject the Participant to taxation under Section 409A, the Participant may elect to reduce the amount of any acceleration of vesting called for under the Award in
order to avoid such characterization. 
 (b) Determination by Tax Firm. To aid the Participant in making any election called
for under Section 10.2(a), 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 Participant as described in Section 10.2(a), 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 

  
 19 

 
“Tax Firm”). As soon as practicable thereafter, the Tax Firm shall determine and report to the Company and the Participant the amount of such acceleration of
vesting, payments and benefits which would produce the greatest after-tax benefit to the Participant. 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 Participant 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. 
  

	 	11.	 TAX WITHHOLDING. 

11.1 Tax Withholding in General. The Company shall have the right to deduct from any and all payments made under the Plan, or to
require the Participant, through payroll withholding, cash payment or otherwise, to make adequate provision for, the federal, state, local and foreign taxes (including social insurance), if any, required by law to be withheld by any Participating
Company with respect to an Award or the shares acquired pursuant thereto. The Company shall have no obligation to deliver shares of Stock, to release shares of Stock from an escrow established pursuant to an Award Agreement, or to make any payment
in cash under the Plan until the Participating Company Group’s tax withholding obligations have been satisfied by the Participant. 

11.2 Withholding in or Directed Sale of Shares. The Company shall have the right, but not the obligation, to deduct from the shares of
Stock issuable to a Participant upon the exercise, vesting or settlement of an Award, or to accept from the Participant the tender of, a number of whole shares of Stock having a Fair Market Value, as determined by the Company, equal to all or any
part of the tax withholding obligations of any Participating Company. The Fair Market Value of any shares of Stock withheld or tendered to satisfy any such tax withholding obligations shall not exceed the amount determined by the applicable minimum
statutory withholding rates. The Company may require a Participant to direct a broker, upon the vesting, exercise or settlement of an Award, to sell a portion of the shares subject to the Award determined by the Company in its discretion to be
sufficient to cover the tax withholding obligations of any Participating Company and to remit an amount equal to such tax withholding obligations to the Participating Company in cash. 

 

	 	12.	 COMPLIANCE WITH SECTION 409A. 

12.1 In General. The Plan and all Awards granted hereunder are intended to comply with, or otherwise be exempt from, Section 409A.
The Plan and all Awards granted under the Plan shall be administered, interpreted, and construed in a manner consistent with Section 409A, as determined by the Company in good faith, to the extent necessary to avoid the imposition of additional
taxes under Section 409A(a)(1)(B) of the Code. It is intended that any election, payment or benefit which is made or provided pursuant to or in connection with any Award that may result in deferred compensation within the meaning of
Section 409A shall comply in all respects with the applicable requirements of Section 409A.  

  
 20 

 12.2 Certain Limitations. With respect to any Award that is subject to
Section 409A, the following shall apply, as applicable: 
 (a) Notwithstanding anything to the contrary in the Plan or any Award
Agreement, to the extent required to avoid tax penalties under Section 409A, amounts that would otherwise be payable and benefits that would otherwise be provided pursuant to the Plan on account of, and during the six (6) month period
immediately following, the Participant’s termination of Service shall instead be paid on the first payroll date after the six-month anniversary of the Participant’s separation from service (or the Participant’s death, if earlier).

 (b) Neither any Participant nor the Company shall take any action to accelerate or delay the payment of any amount or benefits under an
Award in any manner which would not be in compliance with Section 409A. 
 (c) Notwithstanding anything to the contrary in the Plan or
any Award Agreement, to the extent that any amount constituting deferred compensation subject to Section 409A would become payable under the Plan by reason of a Change in Control, such amount shall become payable only if the event constituting
the Change in Control would also constitute a change in ownership or effective control of the Company or a change in the ownership of a substantial portion of the assets of the Company within the meaning of Section 409A. Any Award which
constitutes deferred compensation subject to Section 409A and which would vest and otherwise become payable upon a Change in Control as a result of the failure of the Acquiror to assume, continue or substitute for such Award in accordance with
Section 10.1(b) shall vest to the extent provided by such Award but shall be converted automatically at the effective time of such Change in Control into a right to receive, in cash on the date or dates such award would have been settled in
accordance with its then existing settlement schedule, an amount or amounts equal in the aggregate to the intrinsic value of the Award at the time of the Change in Control. 

(d) Should any provision of the Plan, any Award Agreement, or any other agreement or arrangement contemplated by the Plan be found not to
comply with, or otherwise be exempt from, the provisions of Section 409A, such provision shall be modified and given effect (retroactively if necessary), in the sole discretion of the Board, and without the consent of the holder of the Award,
in such manner as the Board determines to be necessary or appropriate to comply with, or to effectuate an exemption from, Section 409A. 

(e) Notwithstanding the foregoing, neither the Company nor the Board shall have any obligation to take any action to prevent the assessment
of any tax or penalty on any Participant under Section 409A, and neither the Company nor the Board will have any liability to any Participant for such tax or penalty. 
  

	 	13.	 COMPLIANCE WITH SECURITIES LAW.

 The grant of Awards and the issuance of shares of Stock pursuant to any Award shall be subject to compliance with all
applicable requirements of federal, state and foreign law with respect to such securities and the requirements of any stock exchange or market system upon which the Stock may then be listed. In addition, no Award may be exercised or shares issued
pursuant to an Award unless (a) a registration statement under the Securities Act shall at the time of such exercise or issuance be in effect with respect to the shares issuable pursuant to the Award or (b) in the opinion of legal counsel
to the Company, the shares issuable pursuant to 

  
 21 

 
the Award may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. Except as otherwise determined by the Board, the Company
intends that securities issued pursuant to the Plan be exempt from requirements of registration of such securities pursuant to the exemptions afforded by Rule 701 promulgated under the Securities Act or any other applicable exemptions, and the Plan
shall be so construed. 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 and sale of any shares hereunder
shall relieve the Company of any liability in respect of the failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a condition to issuance of any Stock, the Company may require the Participant 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. 

 

	 	14.	 AMENDMENT OR TERMINATION OF
PLAN. 

 The Board may amend, suspend or terminate the Plan at any time. However, without the approval
of the Company’s stockholders, there shall be (a) no increase in the maximum aggregate number of shares of Stock that may be issued under the Plan (except by operation of the provisions of Sections 4.3 and 4.4), (b) no change in the
class of persons eligible to receive Incentive Stock Options, and (c) no other amendment of the Plan that would require approval of the Company’s stockholders under any applicable law, regulation or rule, including the rules of any stock
exchange or quotation system upon which the Stock may then be listed or quoted. No amendment, suspension or termination of the Plan shall affect any then outstanding Award unless expressly provided by the Board. Except as provided by the next
sentence, no amendment, suspension or termination of the Plan may have a materially adverse effect on any then outstanding Award without the consent of the Participant. Notwithstanding any other provision of the Plan or any Award Agreement to the
contrary, the Board may, in its sole and absolute discretion and without the consent of any Participant, amend the Plan or any Award Agreement, to take effect retroactively or otherwise, as it deems necessary or advisable for the purpose of
conforming the Plan or such Award Agreement to any present or future law, regulation or rule applicable to the Plan, including, but not limited to, Section 409A. 
  

	 	15.	 MISCELLANEOUS PROVISIONS. 

15.1 Restrictions on Transfer of Shares.  

(a) Shares issued under the Plan may be subject to a right of first refusal, one or more repurchase options, or other conditions and
restrictions as determined by the Board in its discretion at the time the Award is granted. The Company shall have the right to assign at any time any repurchase right it may have, whether or not such right is then exercisable, to one or more
persons as may be selected by the Company. Upon request by the Company, each Participant shall execute any agreement evidencing such transfer restrictions prior to the receipt of shares of Stock hereunder and shall promptly present to the Company
any and all certificates representing shares of Stock acquired hereunder for the placement on such certificates of appropriate legends evidencing any such transfer restrictions. 

  
 22 

 (b) Notwithstanding the provisions of any Award Agreement to the contrary, at any time
prior to the date on which the Stock is listed on a national securities exchange (as such term is used in the Exchange Act) or is traded on the over-the-counter market and prices therefore are published daily on business days in a recognized
financial journal, the Board may prohibit any Participant who acquires shares of Stock pursuant to the Plan or any transferee of such Participant from selling, transferring, assigning, pledging, or otherwise disposing of or encumbering any such
shares (each, a “Transfer”) without the prior written consent of the Board. The Board may withhold consent to any Transfer for any reason, including without limitation any Transfer (i) to any individual or
entity identified by the Company as a potential competitor or considered by the Company to be unfriendly, or (ii) if such Transfer increases the risk of the Company having a class of security held of record by such number of persons as would
require the Company to register any class of securities under the Exchange Act; or (iii) if such Transfer would result in the loss of any federal or state securities law exemption relied upon by the Company in connection with the initial
issuance of such shares or the issuance of any other securities; or (iv) if such Transfer is facilitated in any manner by any public posting, message board, trading portal, Internet site, or similar method of communication, including without
limitation any trading portal or Internet site intended to facilitate secondary transfers of securities; or (v) if such Transfer is to be effected in a brokered transaction; or (vi) if such Transfer would be of less than all of the shares
of Stock then held by the stockholder and its affiliates or is to be made to more than a single transferee. 
 15.2 Forfeiture
Events. The Board may determine that the Participant’s rights, payments, and benefits with respect to an Award shall be subject to reduction, cancellation, forfeiture, or recoupment upon the occurrence of specified events, in addition to
any otherwise applicable vesting or performance conditions of an Award. Such events may include, but shall not be limited to, termination of Service for Cause, any act by a Participant, whether before or after termination of Service, that would
constitute Cause for termination of Service, or any accounting restatement due to material noncompliance of the Company with any financial reporting requirements of securities laws as a result of which, and to the extent that, such reduction,
cancellation, forfeiture, or recoupment is required by applicable securities laws. 
 15.3 Provision of Information. The Company
shall deliver to each Participant such disclosures as are required in accordance with Rule 701 under the Securities Act. Notwithstanding the foregoing, at any time the Company is relying on the exemption provided by Rule 12h-1(f) under the Exchange
Act, the Company shall provide to the applicable Participants the information described in Securities Act Rules 701(e)(3), (4) and (5) by a method allowed under Rule 12h-1(f)(1)(vi) and in accordance with the requirements of Rule
12h-1(f)(1)(vi), provided that the Participant agrees to keep the information confidential until the Company becomes subject to the reporting requirements of Section 13 or Section 15(d) of the Exchange Act. 

15.4 Rights as Employee, Consultant or Director. No person, even though eligible pursuant to Section 5, shall have a right to be
selected as a Participant, or, having been so selected, to be selected again as a Participant. Nothing in the Plan or any Award granted under the Plan shall confer on any Participant a right to remain an Employee, Consultant or Director or interfere
with or limit in any way any right of a Participating Company to terminate the Participant’s Service at any time. To the extent that an Employee of a Participating Company 

  
 23 

 
other than the Company receives an Award under the Plan, that Award shall in no event be understood or interpreted to mean that the Company is the Employee’s employer or that the Employee
has an employment relationship with the Company. 
 15.5 Rights as a Stockholder. A Participant shall have no rights as a
stockholder with respect to any shares covered by an Award until the date of the issuance of such shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall
be made for dividends, distributions or other rights for which the record date is prior to the date such shares are issued, except as provided in Section 4.3 or another provision of the Plan. 

15.6 Delivery of Title to Shares. Subject to any governing rules or regulations, the Company shall issue or cause to be issued the
shares of Stock acquired pursuant to an Award and shall deliver such shares to or for the benefit of the Participant by means of one or more of the following: (a) by delivering to the Participant evidence of book entry shares of Stock credited
to the account of the Participant, (b) by depositing such shares of Stock for the benefit of the Participant with any broker with which the Participant has an account relationship, or (c) by delivering such shares of Stock to the
Participant in certificate form. 
 15.7 Fractional Shares. The Company shall not be required to issue fractional shares upon the
exercise or settlement of any Award. 
 15.8 Retirement and Welfare Plans. Neither Awards made under this Plan nor shares of Stock
or cash paid pursuant to such Awards may be included as “compensation” for purposes of computing the benefits payable to any Participant under any Participating Company’s retirement plans (both qualified and non-qualified) or welfare
benefit plans unless such other plan expressly provides that such compensation shall be taken into account in computing a Participant’s benefits. 

15.9 Severability. If any one or more of the provisions (or any part thereof) of this Plan shall be held invalid, illegal or
unenforceable in any respect, such provision shall be modified so as to make it valid, legal and enforceable, and the validity, legality and enforceability of the remaining provisions (or any part thereof) of the Plan shall not in any way be
affected or impaired thereby. 
 15.10 No Constraint on Corporate Action. Nothing in this Plan shall be construed to:
(a) limit, impair, or otherwise affect the Company’s or another Participating Company’s right or power to make adjustments, reclassifications, reorganizations, or changes of its capital or business structure, or to merge or
consolidate, or dissolve, liquidate, sell, or transfer all or any part of its business or assets; or (b) limit the right or power of the Company or another Participating Company to take any action which such entity deems to be necessary or
appropriate. 
 15.11 Unfunded Obligation. Participants shall have the status of general unsecured creditors of the Company. Any
amounts payable to Participants pursuant to the Plan shall be considered unfunded and unsecured obligations for all purposes, including, without limitation, Title I of the United States Employee Retirement Income Security Act of 1974. No

  
 24 

 
Participating Company shall be required to segregate any monies from its general funds, or to create any trusts, or establish any special accounts with respect to such obligations. The Company
shall retain at all times beneficial ownership of any investments, including trust investments, which the Company may make to fulfill its payment obligations hereunder. Any investments or the creation or maintenance of any trust or any Participant
account shall not create or constitute a trust or fiduciary relationship between the Board or any Participating Company and a Participant, or otherwise create any vested or beneficial interest in any Participant or the Participant’s creditors
in any assets of any Participating Company. The Participants shall have no claim against any Participating Company for any changes in the value of any assets which may be invested or reinvested by the Company with respect to the Plan. 

15.12 Choice of Law. Except to the extent governed by applicable federal law, the validity, interpretation, construction and
performance of the Plan and each Award Agreement shall be governed by the laws of the State of Texas, without regard to its conflict of law rules. 

15.13 Stockholder Approval. The Plan or any increase in the maximum aggregate number of shares of Stock issuable thereunder as
provided in Section 4.1 (the “Authorized Shares”) shall be approved by a majority of the outstanding securities of the Company entitled to vote within a period beginning twelve (12) months before and ending
twelve (12) months after the date of adoption thereof by the Board. Awards granted prior to security holder approval of the Plan or in excess of the Authorized Shares previously approved by the security holders shall become exercisable no
earlier than the date of security holder approval of the Plan or such increase in the Authorized Shares, as the case may be, and such Awards shall be rescinded if such security holder approval is not received in the manner described in the preceding
sentence. 
 IN WITNESS WHEREOF, the undersigned Secretary of the Company certifies that the foregoing sets forth the BigCommerce Holdings,
Inc. Amended and Restated 2013 Stock Plan as duly adopted by the Board on December 19, 2019.

 THE SECURITIES WHICH ARE THE SUBJECT OF THIS AGREEMENT HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW
TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISPOSITION MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT
REQUIRED UNDER THE SECURITIES ACT OF 1933. 
 BIGCOMMERCE HOLDINGS, INC. 

STOCK OPTION AGREEMENT 

(U.S. Participant; Immediately Exercisable; with Drag Along Rights) 

BigCommerce Holdings, Inc. has granted to the Participant named in the Notice of Grant of Stock Option (the “Grant
Notice”) to which this Stock Option Agreement (the “Option Agreement”) is attached an option (the “Option”) to purchase certain shares of Stock upon the
terms and conditions set forth in the Grant Notice and this Option Agreement. The Option has been granted pursuant to and shall in all respects be subject to the terms and conditions of the BigCommerce Holdings, Inc. 2013 Stock Plan (the
“Plan”), as amended to the Date of Grant, the provisions of which are incorporated herein by reference. By signing the Grant Notice, the Participant: (a) acknowledges receipt of, and represents that the
Participant has read and is familiar with, the Grant Notice, this Option Agreement and the Plan, (b) accepts the Option subject to all of the terms and conditions of the Grant Notice, this Option Agreement and the Plan, and (c) agrees to
accept as binding, conclusive and final all decisions or interpretations of the Board upon any questions arising under the Grant Notice, this Option Agreement or the Plan. 

1. DEFINITIONS AND CONSTRUCTION. 

1.1 Definitions. Unless otherwise defined herein, capitalized terms shall have the meanings assigned to such terms in the
Grant Notice or the Plan. 
 1.2 Construction. Captions and titles contained herein are for convenience only and shall
not affect the meaning or interpretation of any provision of this Option Agreement. Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular. Use of the term “or” is
not intended to be exclusive, unless the context clearly requires otherwise. 
 2. TAX
CONSEQUENCES. 
 2.1 Tax Status of Option. This
Option is intended to have the tax status designated in the Grant Notice. 
 (a) Incentive Stock Option. If the Grant
Notice so designates, this Option is intended to be an Incentive Stock Option within the meaning of Section 422(b) of the Code, but the Company does not represent or warrant that this Option qualifies as such. The Participant should consult
with the Participant’s own tax advisor regarding the tax effects of this Option and the requirements necessary to obtain favorable income tax treatment under 

  
 1 

 
Section 422 of the Code, including, but not limited to, holding period requirements. (NOTE TO PARTICIPANT: If the Option is exercised more than three (3) months after the date on which
you cease to be an Employee (other than by reason of your death or permanent and total disability as defined in Section 22(e)(3) of the Code), the Option will be treated as a Nonstatutory Stock Option and not as an Incentive Stock Option to the
extent required by Section 422 of the Code.) 
 (b) Nonstatutory Stock Option. If the Grant Notice so designates, this
Option is intended to be a Nonstatutory Stock Option and shall not be treated as an Incentive Stock Option within the meaning of Section 422(b) of the Code. 

2.2 Election under Section 83(b) of the Code. If the Participant exercises this Option to purchase shares of Stock
that are both nontransferable and subject to a substantial risk of forfeiture, the Participant understands that the Participant should consult with the Participant’s tax advisor regarding the advisability of filing with the Internal Revenue
Service an election under Section 83(b) of the Code, which must be filed no later than thirty (30) days after the date on which the Participant exercises the Option. Shares acquired upon exercise of the Option are nontransferable and
subject to a substantial risk of forfeiture if they are unvested and are subject to a right of the Company to repurchase such shares at the Participant’s original purchase price if the Participant’s Service terminates. Failure to file an
election under Section 83(b), if appropriate, may result in adverse tax consequences to the Participant. However, an election under Section 83(b) may, under certain circumstances, result in adverse tax consequences to the Participant. The
Participant acknowledges that the Participant has been advised to consult with a tax advisor prior to the exercise of the Option regarding the tax consequences to the Participant of the exercise of the Option and the effect of filing or not filing
an election under Section 83(b). AN ELECTION UNDER SECTION 83(b) MUST BE FILED, IF AT ALL, WITHIN 30 DAYS AFTER THE DATE ON WHICH THE PARTICIPANT PURCHASES SHARES. THIS TIME PERIOD CANNOT BE EXTENDED. THE PARTICIPANT ACKNOWLEDGES THAT TIMELY
FILING OF A SECTION 83(b) ELECTION, IF APPROPRIATE, IS THE PARTICIPANT’S SOLE RESPONSIBILITY, EVEN IF THE PARTICIPANT REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO FILE SUCH ELECTION ON HIS OR HER BEHALF. 

2.3 Notice to Company. The Participant will notify the Company in writing if the Participant files an election pursuant to
Section 83(b) of the Code. The Company intends, in the event it does not receive from the Participant evidence of such filing, to claim a tax deduction for any amount which would otherwise be taxable to the Participant in the absence of such an
election. 
 2.4 ISO Fair Market Value Limitation. If the Grant Notice designates this Option as an Incentive Stock Option,
then to the extent that the Option (together with all Incentive Stock Options granted to the Participant under all stock option plans of the Participating Company Group, including the Plan) becomes exercisable for the first time during any calendar
year for shares having a Fair Market Value greater than One Hundred Thousand Dollars ($100,000), the portion of such options which exceeds such amount will be treated as Nonstatutory Stock Options. For purposes of this Section, options designated as
Incentive Stock Options are taken into account in the order in which they were granted, and the Fair Market 

  
 2 

 
Value of stock is determined as of the time the option with respect to such stock is granted. If the Code is amended to provide for a different limitation from that set forth in this Section,
such different limitation shall be deemed incorporated herein effective as of the date required or permitted by such amendment to the Code. If the Option is treated as an Incentive Stock Option in part and as a Nonstatutory Stock Option in part by
reason of the limitation set forth in this Section, the Participant may designate which portion of such Option the Participant is exercising. In the absence of such designation, the Participant shall be deemed to have exercised the Incentive Stock
Option portion of the Option first. Separate certificates representing each such portion shall be issued upon the exercise of the Option. (NOTE TO PARTICIPANT: If the aggregate Exercise Price of the Option (that is, the Exercise Price multiplied by
the Number of Option Shares) plus the aggregate exercise price of any other Incentive Stock Options you hold (whether granted pursuant to the Plan or any other stock option plan of the Participating Company Group) is greater than $100,000, you
should contact the Chief Financial Officer of the Company to ascertain whether the entire Option qualifies as an Incentive Stock Option.) 

3. ADMINISTRATION. 

All questions of interpretation concerning the Grant Notice, this Option Agreement, the Plan or any other form of agreement or other document
employed by the Company in the administration of the Plan or the Option shall be determined by the Board. All such determinations by the Board shall be final, binding and conclusive upon all persons having an interest in the Option, unless
fraudulent or made in bad faith. Any and all actions, decisions and determinations taken or made by the Board in the exercise of its discretion pursuant to the Plan or the Option or other agreement thereunder (other than determining questions of
interpretation pursuant to the preceding sentence) shall be final, binding and conclusive upon all persons having an interest in the Option. Any Officer shall have the authority to act on behalf of the Company with respect to any matter, right,
obligation, or election which is the responsibility of or which is allocated to the Company herein, provided the Officer has apparent authority with respect to such matter, right, obligation, or election. 

4. EXERCISE OF THE
OPTION. 
 4.1 Right to Exercise. Except as otherwise provided
herein, the Option shall be exercisable on and after the Date of Grant and prior to the termination of the Option (as provided in Section 6) in an amount not to exceed the total Number of Option Shares less the number of shares previously
acquired upon exercise of the Option, subject to the Company’s repurchase rights set forth in Sections 11, 12 and 13 and the Drag Along Rights set forth in Section 14. In no event shall the Option be exercisable for more shares than the
Number of Option Shares, as adjusted pursuant to Section 9, or for fewer than one hundred (100) shares (or such lesser number of shares remaining subject to the Option). 

4.2 Method of Exercise. Exercise of the Option shall be by means of electronic or written notice (the
“Exercise Notice”) in a form authorized by the Company. An electronic Exercise Notice must be digitally signed or authenticated by the Participant in such manner as required by the notice and transmitted to the
Company or an authorized representative of the Company (including a third-party administrator designated by the Company). In the event that the Participant is not authorized or is unable to provide an electronic Exercise Notice, the

  
 3 

 
Option shall be exercised by a written Exercise Notice addressed to the Company, which shall be signed by the Participant and delivered in person, by certified or registered mail, return receipt
requested, by confirmed facsimile transmission, or by such other means as the Company may permit, to the Company, or an authorized representative of the Company (including a third-party administrator designated by the Company). Each Exercise Notice,
whether electronic or written, must state the Participant’s election to exercise the Option, the number of whole shares of Stock for which the Option is being exercised and such other representations and agreements as to the Participant’s
investment intent with respect to such shares as may be required pursuant to the provisions of this Option Agreement. Further, each Exercise Notice must be received by the Company prior to the termination of the Option as set forth in Section 6
and must be accompanied by (a) full payment of the aggregate Exercise Price for the number of shares of Stock being purchased and (b) if the Option is exercised with respect to any Unvested Shares (as defined in Section 11.1), an
Assignment Separate from Certificate duly endorsed (with date and number of shares blank) in the form attached to the Grant Notice. The Option shall be deemed to be exercised upon receipt by the Company of such electronic or written Exercise Notice,
the aggregate Exercise Price and, if required hereby, such duly endorsed Assignment Separate from Certificate. 
 4.3 Payment of Exercise
Price. 
 (a) Forms of Consideration Authorized. Except as otherwise provided below, payment of the aggregate
Exercise Price for the number of shares of Stock for which the Option is being exercised shall be made (i) in cash, by check or in cash equivalent, (ii) if permitted by the Company and subject to the limitations contained in
Section 4.3(b), by means of (1) a Stock Tender Exercise, (2) a Cashless Exercise or (3) a Net-Exercise; or (iii) by any combination of the foregoing. 

(b) Limitations on Forms of Consideration. The Company reserves, at any and all times, the right, in the Company’s sole and
absolute discretion, to establish, decline to approve or terminate any program or procedure providing for payment of the Exercise Price through any of the means described below, including with respect to the Participant notwithstanding that such
program or procedures may be available to others. 
 (i) Stock Tender Exercise. A “Stock Tender
Exercise” means the delivery of a properly executed Exercise Notice accompanied by (1) the Participant’s tender to the Company, or attestation to the ownership, in a form acceptable to the Company of whole shares of
Stock having a Fair Market Value that does not exceed the aggregate Exercise Price for the shares with respect to which the Option is exercised, and (2) the Participant’s payment to the Company in cash of the remaining balance of such
aggregate Exercise Price not satisfied by such shares’ Fair Market Value. A Stock Tender Exercise shall not be permitted if it would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the
Company’s stock. If required by the Company, the Option may not be exercised by tender to the Company, or attestation to the ownership, of shares of Stock unless such shares either have been owned by the Participant for a period of time
required by the Company (and not used for another option exercise by attestation during such period) or were not acquired, directly or indirectly, from the Company. 

  
 4 

 (ii) Cashless Exercise. A Cashless Exercise shall be permitted only upon the class
of shares subject to the Option becoming publicly traded in an established securities market. A “Cashless Exercise” means the delivery of a properly executed Exercise Notice together with irrevocable
instructions to a broker in a form acceptable to the Company providing for the assignment to the Company of the proceeds of a sale or loan with respect to shares of Stock acquired upon the exercise of the Option in an amount not less than the
aggregate Exercise Price for such shares (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board of Governors of the Federal Reserve System). 

(iii) Net-Exercise. A
“Net-Exercise” means the delivery of a properly executed Exercise Notice electing a procedure pursuant to which (1) the Company will reduce the number of shares
otherwise issuable to the Participant upon the exercise of the Option by the largest whole number of shares having a Fair Market Value that does not exceed the aggregate Exercise Price for the shares with respect to which the Option is exercised,
and (2) the Participant shall pay to the Company in cash the remaining balance of such aggregate Exercise Price not satisfied by such reduction in the number of whole shares to be issued. Following a
Net-Exercise, the number of shares remaining subject to the Option, if any, shall be reduced by the sum of (1) the net number of shares issued to the Participant upon such exercise, and (2) the
number of shares deducted by the Company for payment of the aggregate Exercise Price. 
 4.4 Tax Withholding. 

(a) In General. At the time the Option is exercised, in whole or in part, or at any time thereafter as requested by a
Participating Company, the Participant hereby authorizes withholding from payroll and any other amounts payable to the Participant, and otherwise agrees to make adequate provision for any sums required to satisfy the federal, state, local and
foreign tax (including any social insurance) withholding obligations of the Participating Company Group, if any, which arise in connection with the Option. The Company shall have no obligation to deliver shares of Stock until the tax withholding
obligations of the Participating Company Group have been satisfied by the Participant. 
 (b) Withholding in or Directed Sale of
Shares. The Company shall have the right, but not the obligation, to require the Participant to satisfy all or any portion of a Participating Company’s tax withholding obligations upon exercise of the Option by deducting from the
shares of Stock otherwise issuable to the Participant upon such exercise a number of whole shares having a fair market value, as determined by the Company as of the date of exercise, not in excess of the amount of such tax withholding obligations
determined by the applicable minimum statutory withholding rates. The Company may require the Participant to direct a broker, upon the exercise of the Option, to sell a portion of the shares subject to the Option determined by the Company in its
discretion to be sufficient to cover the tax withholding obligations of any Participating Company and to remit an amount equal to such tax withholding obligations to the Company in cash. 

  
 5 

 4.5 Beneficial Ownership of Shares; Certificate Registration. The
Participant hereby authorizes the Company, in its sole discretion, to deposit the shares acquired pursuant to the exercise of the Option with the Company’s transfer agent, including any successor transfer agent, to be held in book entry form
during the term of the Escrow pursuant to Section 16. Furthermore, the Participant hereby authorizes the Company, in its sole discretion, to deposit, following the term of the Escrow, for the benefit of the Participant with any broker with
which the Participant has an account relationship of which the Company has notice any or all such shares which are no longer subject to the Escrow. Except as provided by the foregoing, a certificate for the shares shall be registered in the name of
the Participant, or, if applicable, in the names of the heirs of the Participant. 
 4.6 Restrictions on Grant of the Option and Issuance
of Shares. The grant of the Option and the issuance of shares of Stock upon exercise of the Option shall be subject to compliance with all applicable requirements of federal, state or foreign law with respect to such securities.
The Option may not be exercised if the issuance of shares of Stock upon exercise 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. In addition, the Option may not be exercised unless (i) a registration statement under the Securities Act shall at the time of exercise of the Option be in effect with respect to the shares
issuable upon exercise of the Option or (ii) in the opinion of legal counsel to the Company, the shares issuable upon exercise of the Option may be issued in accordance with the terms of an applicable exemption from the registration
requirements of the Securities Act. THE PARTICIPANT IS CAUTIONED THAT THE OPTION MAY NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED. ACCORDINGLY, THE PARTICIPANT MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED EVEN THOUGH THE
OPTION IS VESTED. 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 and sale of any shares subject to the
Option shall relieve the Company of any liability in respect of the failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a condition to the exercise of the Option, the Company may require the
Participant 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. 

4.7 Fractional Shares. The Company shall not be required to issue fractional shares upon the exercise of the Option. 

5. NONTRANSFERABILITY OF THE
OPTION. 
 During the lifetime of the Participant, the Option shall be
exercisable only by the Participant or the Participant’s guardian or legal representative. The Option shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by
creditors of the Participant or the Participant’s beneficiary, except transfer by will or by the laws of descent and distribution. Following the death of the Participant, the Option, to the extent provided in Section 7, may be exercised by
the Participant’s legal representative or by any person empowered to do so under the deceased Participant’s will or under the then applicable laws of descent and distribution. Notwithstanding the foregoing, for so long as the Company is
relying on the exemption provided by Rule 12h-1(f) under the Exchange Act, the Option and, prior to its exercise, the shares to be issued upon the exercise of the Option, shall not be transferred except in
compliance with the restrictions on transfer under Rule 12h-1(f) (including the requirement under such rule that any permitted transferee may not further transfer the Option) or be made subject to any short
position, “put equivalent position” or “call equivalent position” by the Participant, as such terms are defined in Rule 16a-1 of the Exchange Act. 

  
 6 

 6. TERMINATION OF THE
OPTION. 
 The Option shall terminate and may no longer be exercised after
the first to occur of (a) the close of business on the Option Expiration Date, (b) the close of business on the last date for exercising the Option following termination of the Participant’s Service as described in Section 7, or
(c) a Change in Control to the extent provided in Section 8. 
 7. EFFECT OF
TERMINATION OF SERVICE. 
 7.1 Option
Exercisability. The Option shall terminate immediately upon the Participant’s termination of Service to the extent that it is then unvested and shall be exercisable after the Participant’s termination of Service to the extent it is
then vested only during the applicable time period as determined below and thereafter shall terminate. 
 (a)
Disability. If the Participant’s Service terminates because of the Disability of the Participant, the Option, to the extent unexercised and exercisable for Vested Shares on the date on which the Participant’s Service
terminated, may be exercised by the Participant (or the Participant’s guardian or legal representative) at any time prior to the expiration of one hundred eighty (180) days after the date on which the Participant’s Service terminated,
but in any event no later than the Option Expiration Date. 
 (b) Death. If the Participant’s Service terminates
because of the death of the Participant, the Option, to the extent unexercised and exercisable for Vested Shares on the date on which the Participant’s Service terminated, may be exercised by the Participant’s legal representative or other
person who acquired the right to exercise the Option by reason of the Participant’s death at any time prior to the expiration of one hundred eighty (180) days after the date on which the Participant’s Service terminated, but in any
event no later than the Option Expiration Date. The Participant’s Service shall be deemed to have terminated on account of death if the Participant dies within ninety (90) days after the Participant’s termination of Service. 

(c) Termination for Cause. Notwithstanding any other provision of this Option Agreement, if the Participant’s Service is
terminated for Cause, the Option shall terminate in its entirety and cease to be exercisable immediately upon such termination of Service. 

(d) Other Termination of Service. If the Participant’s Service terminates for any reason, except Disability, death
or Cause, the Option, to the extent unexercised and exercisable for Vested Shares by the Participant on the date on which the Participant’s Service terminated, may be exercised by the Participant at any time prior to the expiration of ninety
(90) days after the date on which the Participant’s Service terminated, but in any event no later than the Option Expiration Date. 

  
 7 

 7.2 Extension if Exercise Prevented by Law. Notwithstanding the
foregoing other than termination of the Participant’s Service for Cause, if the exercise of the Option within the applicable time periods set forth in Section 7.1 is prevented by the provisions of Section 4.6, the Option shall remain
exercisable until the later of (a) thirty (30) days after the date such exercise first would no longer be prevented by such provisions or (b) the end of the applicable time period under Section 7.1, but in any event no later than
the Option Expiration Date. 
 8. EFFECT OF CHANGE IN
CONTROL. 
 In the event that there is both a Change of Control, except to
the extent that the Board determines to settle the Option in accordance with Section 10.1(c) of the Plan, the surviving, continuing, successor, or purchasing corporation or other business entity or parent thereof, as the case may be (the
“Acquiror”), may, without the consent of the Participant, assume or continue in full force and effect the Company’s rights and obligations under all or any portion of the Option or substitute for all or any
portion of the Option a substantially equivalent option for the Acquiror’s stock. For purposes of this Section, the Option or any portion thereof shall be deemed assumed if, following the Change in Control, the Option confers the right to
receive, subject to the terms and conditions of the Plan and this Option Agreement, for each share of Stock subject to such portion of the Option immediately prior to the Change in Control, the consideration (whether stock, cash, other securities or
property or a combination thereof) to which a holder of a share of Stock on the effective date of the Change in Control was entitled (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a
majority of the outstanding shares of Stock); provided, however, that if such consideration is not solely common stock of the Acquiror, the Board may, with the consent of the Acquiror, provide for the consideration to be received upon the exercise
of the Option for each share of Stock to consist solely of common stock of the Acquiror equal in Fair Market Value to the per share consideration received by holders of Stock pursuant to the Change in Control. If any portion of such consideration
may be received by holders of Stock pursuant to the Change in Control on a contingent or delayed basis, the Board may, in its discretion, determine such Fair Market Value per share as of the time of the Change in Control on the basis of the
Board’s good faith estimate of the present value of the probable future payment of such consideration. The Option shall terminate and cease to be outstanding effective as of the time of consummation of the Change in Control to the extent that
the Option is neither assumed or continued by the Acquiror in connection with the Change in Control nor exercised as of the time of the Change in Control. Notwithstanding the foregoing, shares acquired upon exercise of the Option prior to the Change
in Control and any consideration received pursuant to the Change in Control with respect to such shares shall continue to be subject to all applicable provisions of this Option Agreement except as otherwise provided herein. 

9. ADJUSTMENTS FOR CHANGES IN CAPITAL
STRUCTURE. 
 Subject to any required action by the stockholders of the
Company and the requirements of Sections 409A and 424 of the Code to the extent applicable, in the event of any change in the Stock effected without receipt of consideration by the Company, whether through merger, consolidation, reorganization,
reincorporation, recapitalization, reclassification, stock dividend, stock split, reverse stock split, split-up, split-off,
spin-off, combination of shares, exchange of shares, or similar change in the capital structure of the Company, or in the event of payment of a 

  
 8 

 
dividend or distribution to the stockholders of the Company in a form other than Stock (excepting normal cash dividends) that has a material effect on the Fair Market Value of shares of Stock,
appropriate and proportionate adjustments shall be made in the number, Exercise Price and kind of shares subject to the Option, in order to prevent dilution or enlargement of the Participant’s rights under the Option. 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 fractional share resulting from an adjustment pursuant to this Section shall be
rounded down to the nearest whole number, and the Exercise Price shall be rounded up to the nearest whole cent. In no event may the Exercise Price be decreased to an amount less than the par value, if any, of the stock subject to the Option. Such
adjustments shall be determined by the Board, and its determination shall be final, binding and conclusive. 
 10.
RIGHTS AS A STOCKHOLDER, DIRECTOR, EMPLOYEE OR CONSULTANT. 

The Participant shall have no rights as a stockholder with respect to any shares covered by the Option until the date of the issuance of the
shares for which the Option has been exercised (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for
which the record date is prior to the date the shares are issued, except as provided in Section 9. If the Participant is an Employee, the Participant understands and acknowledges that, except as otherwise provided in a separate, written
employment agreement between a Participating Company and the Participant, the Participant’s employment is “at will” and is for no specified term. Nothing in this Option Agreement shall confer upon the Participant any right to continue
in the Service of a Participating Company or interfere in any way with any right of the Participating Company Group to terminate the Participant’s Service as a Director, an Employee or Consultant, as the case may be, at any time. 

11. UNVESTED SHARE REPURCHASE
OPTION. 
 11.1 Grant of Unvested Share Repurchase
Option. In the event the Participant’s Service is terminated for any reason or no reason, with or without cause, or, if the Participant, the Participant’s legal representative, or other holder of shares
acquired pursuant to this Agreement, attempts to sell, exchange, transfer, pledge, or otherwise dispose of (other than pursuant to an Ownership Change Event) any Unvested Shares, as defined in Section 11.2 below (the “Unvested
Shares”), the Company shall have the right to repurchase the Unvested Shares under the terms and subject to the conditions set forth in this Section 11 (the “Unvested Share Repurchase
Option”). 
 11.2 Unvested Shares Defined. The “Unvested
Shares” shall mean, on any given date, the number of shares of Stock acquired upon exercise of the Option which exceed the Vested Shares determined as of such date. 

11.3 Exercise of Unvested Share Repurchase Option. The Company may exercise the Unvested Share Repurchase Option by
written notice to the Participant within one (1) year after (a) termination of the Participant’s Service or (b) the Company has received notice of the attempted disposition of Unvested Shares. If the Company fails to give notice
within such one-year period, the Unvested Share Repurchase Option shall terminate unless the Company and 

  
 9 

 
the Participant have extended the time for the exercise of the Unvested Share Repurchase Option. Notwithstanding the preceding sentence, the period during which the Company may exercise the
Unvested Share Repurchase Option shall terminate no sooner than the completion of a period of six (6) months following the date on which the Participant acquired the Unvested Shares upon exercise of the Option. The Unvested Share Repurchase
Option must be exercised, if at all, for all of the Unvested Shares, except as the Company and the Participant otherwise agree. 
 11.4
Payment for Shares and Return of Shares to Company. The purchase price per share being repurchased by the Company (the “Repurchase Price”) shall be an amount equal to the lesser of
(a) the Participant’s original cost per share, as adjusted pursuant to Section 9, and (b) the Fair Market Value per share as of the date of repurchase. The Company shall pay the aggregate Repurchase Price to the Participant in
cash, by promissory note, or a combination thereof within fifteen (15) days after the date of the written notice to the Participant of the Company’s exercise of the Unvested Share Repurchase Option. For purposes of the foregoing,
cancellation of any purchase money indebtedness of the Participant to any Participating Company for the shares shall be treated as payment to the Participant in cash to the extent of the unpaid principal and any accrued interest canceled. Any such
promissory note will provide for substantially equal installments, payable at least annually, over a period not to exceed five years and will accrue simple interest at the applicable Federal mid-term rate in
effect under Section 1274(d) of the Code as of the repurchase date. The shares being repurchased shall be delivered to the Company by the Participant at the same time as the delivery of the Repurchase Price to the Participant. 

11.5 Assignment of Unvested Share Repurchase Option. The Company shall have the right to assign the Unvested Share
Repurchase Option at any time, whether or not such option is then exercisable, to one or more persons as may be selected by the Company. 

11.6 Ownership Change Event. Upon the occurrence of an Ownership Change Event, any and all new, substituted or additional
securities or other property to which the Participant is entitled by reason of the Participant’s ownership of Unvested Shares shall be immediately subject to the Unvested Share Repurchase Option and included in the terms “Stock” and
“Unvested Shares” for all purposes of the Unvested Share Repurchase Option with the same force and effect as the Unvested Shares immediately prior to the Ownership Change Event. While the aggregate Repurchase Price shall remain the same
after such Ownership Change Event, the Repurchase Price per Unvested Share upon exercise of the Unvested Share Repurchase Option following such Ownership Change Event shall be adjusted as appropriate. 

12. RIGHT OF FIRST
REFUSAL. 
 12.1 Grant of Right of First Refusal.
Except as provided in Section 12.7 and Section 20 below, in the event the Participant, the Participant’s legal representative, or other holder of shares acquired upon exercise of the Option proposes to sell, exchange, transfer,
pledge, or otherwise dispose of any Vested Shares (the “Transfer Shares”) to any person or entity, including, without limitation, any stockholder of a Participating Company, the Company shall have the right to
repurchase the Transfer Shares under the terms and subject to the conditions set forth in this Section 12 (the “Right of First Refusal”). 

  
 10 

 12.2 Notice of Proposed Transfer. Prior to any proposed transfer of the
Transfer Shares, the Participant shall deliver written notice (the “Transfer Notice”) to the Company describing fully the proposed transfer, including the number of Transfer Shares, the name and address of the
proposed transferee (the “Proposed Transferee”) and, if the transfer is voluntary, the proposed transfer price, and containing such information necessary to show the bona fide nature of the proposed transfer. In
the event of a bona fide gift or involuntary transfer, the proposed transfer price shall be deemed to be the Fair Market Value of the Transfer Shares, as determined by the Board in good faith. If the Participant proposes to transfer any Transfer
Shares to more than one Proposed Transferee, the Participant shall provide a separate Transfer Notice for the proposed transfer to each Proposed Transferee. The Transfer Notice shall be signed by both the Participant and the Proposed Transferee and
must constitute a binding commitment of the Participant and the Proposed Transferee for the transfer of the Transfer Shares to the Proposed Transferee subject only to the Right of First Refusal. 

12.3 Bona Fide Transfer. If the Company determines that the information provided by the Participant in the Transfer Notice
is insufficient to establish the bona fide nature of a proposed voluntary transfer, the Company shall give the Participant written notice of the Participant’s failure to comply with the procedure described in this Section 12, and the
Participant shall have no right to transfer the Transfer Shares without first complying with the procedure described in this Section 12. The Participant shall not be permitted to transfer the Transfer Shares if the proposed transfer is not bona
fide. 
 12.4 Exercise of Right of First Refusal. If the Company determines the proposed transfer to be bona fide, the
Company shall have the right to purchase all, but not less than all, of the Transfer Shares (except as the Company and the Participant otherwise agree) at the purchase price and on the terms set forth in the Transfer Notice by delivery to the
Participant of a notice of exercise of the Right of First Refusal within thirty (30) days after the date the Transfer Notice is delivered to the Company. The Company’s exercise or failure to exercise the Right of First Refusal with respect
to any proposed transfer described in a Transfer Notice shall not affect the Company’s right to exercise the Right of First Refusal with respect to any proposed transfer described in any other Transfer Notice, whether or not such other Transfer
Notice is issued by the Participant or issued by a person other than the Participant with respect to a proposed transfer to the same Proposed Transferee. If the Company exercises the Right of First Refusal, the Company and the Participant shall
thereupon consummate the sale of the Transfer Shares to the Company on the terms set forth in the Transfer Notice within sixty (60) days after the date the Transfer Notice is delivered to the Company (unless a longer period is offered by the
Proposed Transferee); provided, however, that in the event the Transfer Notice provides for the payment for the Transfer Shares other than in cash, the Company shall have the option of paying for the Transfer Shares by the present value cash
equivalent of the consideration described in the Transfer Notice as reasonably determined by the Company. For purposes of the foregoing, cancellation of any indebtedness of the Participant to any Participating Company shall be treated as payment to
the Participant in cash to the extent of the unpaid principal and any accrued interest canceled. Notwithstanding anything contained in this Section to the contrary, the period during which the Company may exercise the Right of First Refusal and
consummate the purchase of the Transfer Shares from the Participant shall terminate no sooner than the completion of a period of eight (8) months following the date on which the Participant acquired the Transfer Shares upon exercise of the
Option. 

  
 11 

 12.5 Failure to Exercise Right of First Refusal. If the Company fails
to exercise the Right of First Refusal in full (or to such lesser extent as the Company and the Participant otherwise agree) within the period specified in Section 12.4 above, the Participant may conclude a transfer to the Proposed Transferee
of the Transfer Shares on the terms and conditions described in the Transfer Notice, provided such transfer occurs not later than ninety (90) days following delivery to the Company of the Transfer Notice or, if applicable, following the end of
the period described in the last sentence of Section 12.4. The Company shall have the right to demand further assurances from the Participant and the Proposed Transferee (in a form satisfactory to the Company) that the transfer of the Transfer
Shares was actually carried out on the terms and conditions described in the Transfer Notice. No Transfer Shares shall be transferred on the books of the Company until the Company has received such assurances, if so demanded, and has approved the
proposed transfer as bona fide. Any proposed transfer on terms and conditions different from those described in the Transfer Notice, as well as any subsequent proposed transfer by the Participant, shall again be subject to the Right of First Refusal
and shall require compliance by the Participant with the procedure described in this Section 12. 
 12.6 Transferees of Transfer
Shares. All transferees of the Transfer Shares or any interest therein, other than the Company, shall be required as a condition of such transfer to agree in writing (in a form satisfactory to the Company) that such transferee
shall receive and hold such Transfer Shares or interest therein subject to all of the terms and conditions of this Option Agreement, including this Section 12 providing for the Right of First Refusal with respect to any subsequent transfer. Any
sale or transfer of any shares acquired upon exercise of the Option shall be void unless the provisions of this Section 12 are met. 

12.7 Transfers Not Subject to Right of First Refusal. The Right of First Refusal shall not apply to any transfer or
exchange of the shares acquired upon exercise of the Option if such transfer or exchange is in connection with an Ownership Change Event. If the consideration received pursuant to such transfer or exchange consists of stock of a Participating
Company, such consideration shall remain subject to the Right of First Refusal unless the provisions of Section 12.9 below result in a termination of the Right of First Refusal. 

12.8 Assignment of Right of First Refusal. The Company shall have the right to assign the Right of First Refusal at any
time, whether or not there has been an attempted transfer, to one or more persons as may be selected by the Company. 
 12.9 Early
Termination of Right of First Refusal. The other provisions of this Option Agreement notwithstanding, the Right of First Refusal shall terminate and be of no further force and effect upon (a) the occurrence of a Change in
Control, unless the Acquiror assumes the Company’s rights and obligations under the Option or substitutes a substantially equivalent option for the Acquiror’s stock for the Option, or (b) the existence of a public market for the class
of shares subject to the Right of First Refusal. A “public market” shall be deemed to exist if (i) such stock is listed on a national securities exchange (as that term is used in the Exchange Act) or
(ii) such stock is traded on the over-the-counter market and prices therefor are published daily on business days in a recognized financial journal. 

  
 12 

 13. VESTED SHARE REPURCHASE
OPTION. 
 13.1 Grant of Vested Share Repurchase Option. Except as provided in Section 13.4
below, in the event of the occurrence of any Repurchase Event, as defined below, the Company shall have the right to repurchase the shares acquired by the Participant pursuant to the Option (the “Repurchase
Shares”) under the terms and subject to the conditions set forth in this Section 13 (the “Vested Share Repurchase Option”). Each of the following events shall
constitute a “Repurchase Event”: 
 (a) Termination of the Participant’s Service with the
Participating Company Group for any reason or no reason, with or without cause, including death or Disability. The Repurchase Period, as defined below, shall commence on the date of termination of the Participant’s Service. 

(b) The Participant, the Participant’s legal representative, or other holder of shares acquired upon exercise of the Option attempts to
sell, exchange, transfer, pledge, or otherwise dispose of any Repurchase Shares without complying with the provisions of Section 12. The Repurchase Period, as defined below, shall commence on the date the Company receives actual notice of such
attempted sale, exchange, transfer, pledge or other disposition. 
 (c) The receivership, bankruptcy or other creditor’s proceeding
regarding the Participant or the taking of any of the Participant’s shares of Stock by legal process, such as a levy of execution. The Repurchase Period, as defined below, shall commence on the date the Company receives actual notice of the
commencement of pendency of the receivership, bankruptcy or other creditor’s proceeding or the date of such taking, as the case may be. The Fair Market Value of the Repurchase Shares shall be determined as of the last day of the month preceding
the month in which the proceeding involved commenced or the taking occurred. 
 13.2 Exercise of Vested Share Repurchase Option. The
Company may exercise the Vested Share Repurchase Option by written notice to the Participant, the Participant’s legal representative, or other holder of the Repurchase Shares, as the case may be, during the Repurchase Period. The
“Repurchase Period” shall be the period commencing at the time set forth in Section 13.1 above and ending on the later of (a) the date ninety (90) days after the commencement of the Repurchase
Period or (b) the date nine (9) months after the Option is last exercised. If the Company fails to give notice during the Repurchase Period, the Vested Share Repurchase Option shall terminate (unless the Company and the Participant have
extended the time for the exercise of the Vested Share Repurchase Option) unless and until there is a subsequent Repurchase Event. Notwithstanding a termination of the Vested Share Repurchase Option, the remaining provisions of this Option Agreement
shall remain in full force and effect, including, without limitation, the Right of First Refusal set forth in Section 12. If there is a subsequent Repurchase Event, the Vested Share Repurchase Option shall again become exercisable as provided
in this Section 13. The Vested Share Repurchase Option must be exercised, if at all, for all of the Repurchase Shares, except as the Company and the Participant otherwise agree. 

  
 13 

 13.3 Payment for Repurchase Shares. The repurchase price per share being repurchased
by the Company pursuant to the Vested Share Repurchase Option shall be an amount equal to the Fair Market Value of the shares determined as of the date of the Repurchase Event (except as otherwise provided in Section 13.1(c) above) by the Board
in good faith. Payment by the Company to the Participant shall be made in cash, by promissory note, or a combination thereof on or before the last day of the Repurchase Period. For purposes of the foregoing, cancellation of any indebtedness of the
Participant to the Company shall be treated as payment to the Participant in cash to the extent of the unpaid principal and any accrued interest canceled. Any such promissory note will provide for substantially equal installments, payable at least
annually, over a period not to exceed five years and will accrue simple interest at the applicable Federal mid-term rate in effect under Section 1274(d) of the Code as of the repurchase date. The shares
being repurchased shall be delivered to the Company by the Participant at the same time as the delivery of the Repurchase Price to the Participant. 

13.4 Transfers Not Subject to Vested Share Repurchase Option. The Vested Share Repurchase Option shall not apply to any transfer or
exchange of shares acquired upon exercise of the Option if such transfer or exchange is in connection with an Ownership Change Event. If the consideration received pursuant to such transfer or exchange consists of stock of a Participating Company,
such consideration will remain subject to the Vested Share Repurchase Option unless the provisions of Section 13.6 below result in a termination of the Vested Share Repurchase Option. Furthermore, the Vested Share Repurchase Option shall not
apply to a transfer to the Participant’s ancestors, descendants, or spouse or to a custodian or trustee solely for the benefit of the Participant or the Participant’s ancestors, descendants, or spouse; provided, however, that such
transferee shall agree in writing (in a form satisfactory to the Company) to receive and hold the shares transferred to the transferee subject to all the terms and conditions of this Option Agreement, including this Section 13 providing for a
Vested Share Repurchase Option with respect to any subsequent transfer. 
 13.5 Assignment of Vested Share Repurchase Option. The
Company shall have the right to assign the Vested Share Repurchase Option at any time, whether or not such option is then exercisable, to one or more persons as may be selected by the Company. 

13.6 Early Termination of Vested Share Repurchase Option. The other provisions of this Option Agreement notwithstanding, the Vested
Share Repurchase Option shall terminate and be of no further force and effect upon (a) the occurrence of a Change in Control, unless the Acquiring Corporation assumes or continues the Company’s rights and obligations under the Option or
substitutes a substantially equivalent option for the Acquiring Corporation’s stock for the Option, or (b) the existence of a public market, as defined in Section 12.9, for the class of shares subject to the Vested Share Repurchase
Option. 
 14. DRAG ALONG RIGHTS. 

14.1 Applicable Shares. The Participant agrees that any shares acquired upon exercise of the Option, including all shares issued in
respect of any shares acquired upon exercise of the Option by way of stock split, stock dividend and the like (the “Applicable Shares”) will be subject to, and must be voted in accordance with, the provisions of this
Section 14. 

  
 14 

 14.2 Obligations of Participant. In the event that the Board approves and recommends
an Ownership Change Event, the Participant hereby agrees to: 
 (a) consent to, vote all Applicable Shares for and raise no objections to,
the Ownership Change Event; 
 (b) sell all Applicable Shares on the terms and conditions approved by the Board, provided that such
terms do not provide that the Participant would receive less than the amount that would be distributed to such Participant in the event the proceeds of the Ownership Change Event were distributed in accordance with the Company’s Certificate of
Incorporation then in effect; and 
 (c) take all necessary and desirable actions in connection with the consummation of the Ownership
Change Event, including the execution of such agreements and such instruments and other actions reasonably necessary to provide the representations, warranties, indemnities, covenants, conditions, non-compete
agreements, escrow agreements and other provisions and agreements relating to the Ownership Change. 
 14.3 Transfer of Applicable
Shares. This Section 14 shall be binding upon the successors in interest to any of the Applicable Shares. The Company shall not register the transfer of any of the Applicable Shares or issue a new certificate representing any of the
Applicable Shares unless and until the transferee shall have executed an adoption agreement, pursuant to which such person agrees to be bound by the terms of this Section 14 as and to the same extent as if he, she or it were an original party
hereto. Any transfer of shares in contravention of the foregoing shall be void ab initio. 
 14.4 Irrevocable Proxy. To
insure the performance of the Participant with the provisions set forth in this Section 14, the Participant hereby appoints the Company, or its designee, as his, her, or its true and lawful proxy and attorney-in-fact, with full power of substitution and resubstitution, to vote all Applicable Shares owned or held by such Participant, subject to the provisions of this Section 14, upon any matter
presented to the stockholders of the Company, if (and only if) such Participant fails to comply with the provisions of this Section 14. The proxies and powers granted by the Participant pursuant to the preceding sentence are coupled with an
interest and are given to secure the performance of such Participant’s commitments under this Section 14. Such proxies shall be irrevocable for the term of this Section 14 and shall survive the death, incompetency, disability,
dissolution or winding up of such Participant. 
 14.5 Specific Enforcement. It is agreed and understood that monetary damages would
not adequately compensate the Company for the breach of this Section 14 by the Participant, that this Section 14 shall be specifically enforceable, and that any breach or threatened breach of this Section 14 shall be the proper
subject of a temporary or permanent injunction or restraining order. Further, the Participant waives any claim or defense that there is an adequate remedy at law for such breach or threatened breach. 

  
 15 

 15. STOCK DISTRIBUTIONS SUBJECT
TO OPTION AGREEMENT. 
 If, from time to
time, there is any stock dividend, stock split or other change, as described in Section 9, in the character or amount of any of the outstanding stock of the corporation the stock of which is subject to the provisions of this Option Agreement,
then in such event any and all new, substituted or additional securities to which the Participant is entitled by reason of the Participant’s ownership of the shares acquired upon exercise of the Option shall be immediately subject to the
Unvested Share Repurchase Option, the Right of First Refusal, the Vested Share Repurchase Option and the Drag Along Rights with the same force and effect as the shares subject to the Unvested Share Repurchase Option, the Right of First Refusal, the
Vested Share Repurchase Option and the Drag Along Rights immediately before such event. 
 16.
ESCROW. 
 16.1 Appointment of Agent. To ensure that shares
subject to the Unvested Share Repurchase Option will be available for repurchase, the Participant and the Company hereby appoint the Secretary of the Company, or any other person designated by the Company, as their agent and as attorney-in-fact for the Participant (the “Agent”) to hold any and all Unvested Shares and to sell, assign and transfer to the Company
any such Unvested Shares repurchased by the Company pursuant to the Unvested Share Repurchase Option. The Participant understands that appointment of the Agent is a material inducement to make this Agreement and that such appointment is coupled with
an interest and is irrevocable. The Agent shall not be personally liable for any act the Agent may do or omit to do hereunder as escrow agent, agent for the Company, or attorney in fact for the Participant while acting in good faith and in the
exercise of the Agent’s own good judgment, and any act done or omitted by the Agent pursuant to the advice of the Agent’s own attorneys shall be conclusive evidence of such good faith. The Agent may rely upon any letter, notice or other
document executed by any signature purporting to be genuine and may resign at any time. 
 16.2 Establishment of Escrow.
The Participant authorizes the Company to deposit the Unvested Shares with the Company’s transfer agent to be held in book entry form, as provided by Section 4.5, and the Participant agrees to deliver to and deposit with the Agent each
certificate, if any, evidencing the Unvested Shares and an Assignment Separate from Certificate with respect to such book entry shares and each such certificate duly endorsed (with date and number of shares blank) in the form attached to this
Agreement, to be held by the Agent under the terms and conditions of this Section (the “Escrow”). Upon the occurrence of an Ownership Change Event, a dividend or distribution to the stockholders of the Company
paid in shares of Stock or other property (other than regular, periodic dividends paid on Stock pursuant to the Company’s dividend policy), or any other adjustment upon a change in the capital structure of the Company, as described in
Section 9, any and all new, substituted or additional securities or other property to which the Participant is entitled by reason of his or her ownership of the shares that remain, following such Ownership Change Event, dividend, distribution
or change described in Section 9, subject to the Unvested Share Repurchase Option shall be immediately subject to the Escrow to the same extent as the shares immediately before such event. The Company shall bear the expenses of the Escrow. 

  
 16 

 16.3 Delivery of Shares to Participant. The Escrow shall continue with
respect to any shares for so long as such shares remain subject to the Unvested Share Repurchase Option. Upon termination of the Unvested Share Repurchase Option with respect to shares, the Company shall so notify the Agent and direct the Agent to
deliver such number of shares to the Participant. As soon as practicable after receipt of such notice, the Agent shall cause to be delivered to the Participant the shares specified by such notice, and the Escrow shall terminate with respect to such
shares. 
 16.4 Notices and Payments. In the event the shares and any other property held in escrow are subject to the
Company’s exercise of the Unvested Share Repurchase Option, the Right of First Refusal, the Vested Share Repurchase Option or the Drag Along Rights, the notices required to be given to the Participant shall be given to the Agent, and any
payment required to be given to the Participant shall be given to the Agent. Within thirty (30) days after payment by the Company, the Agent shall deliver the shares and any other property which the Company has purchased to the Company and
shall deliver the payment received from the Company to the Participant. 
 17. NOTICE OF
SALES UPON DISQUALIFYING DISPOSITION. 

The Participant shall dispose of the shares acquired pursuant to the Option only in accordance with the provisions of this Option Agreement. In
addition, if the Grant Notice designates this Option as an Incentive Stock Option, the Participant shall (a) promptly notify the Chief Financial Officer of the Company if the Participant disposes of any of the shares acquired pursuant to
the Option within one (1) year after the date the Participant exercises all or part of the Option or within two (2) years after the Date of Grant and (b) provide the Company with a description of the circumstances of such disposition.
Until such time as the Participant disposes of such shares in a manner consistent with the provisions of this Option Agreement, unless otherwise expressly authorized by the Company, the Participant shall hold all shares acquired pursuant to the
Option in the Participant’s name (and not in the name of any nominee) for the one-year period immediately after the exercise of the Option and the two-year period
immediately after Date of Grant. At any time during the one-year or two-year periods set forth above, the Company may place a legend on any certificate representing
shares acquired pursuant to the Option requesting the transfer agent for the Company’s stock to notify the Company of any such transfers. The obligation of the Participant to notify the Company of any such transfer shall continue
notwithstanding that a legend has been placed on the certificate pursuant to the preceding sentence. 
 18.
LEGENDS. 
 The Company may at any time place legends referencing
the Unvested Share Repurchase Option, the Right of First Refusal, the Vested Share Repurchase Option, the Drag Along Rights and any applicable federal, state or foreign securities law restrictions on all certificates representing shares of stock
subject to the provisions of this Option Agreement. The Participant shall, at the request of the Company, promptly present to the Company any and all certificates representing shares acquired pursuant to the Option in the possession of the
Participant in order to carry out the provisions of this Section. Unless otherwise specified by the Company, legends placed on such certificates may include, but shall not be limited to, the following: 

  
 17 

 18.1 “THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN ACCORDANCE WITH RULE 144 OR RULE 701
UNDER THE ACT, OR THE COMPANY RECEIVES AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH
ACT.” 
 18.2 “THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND REPURCHASE OPTIONS IN
FAVOR OF THE CORPORATION OR ITS ASSIGNEE SET FORTH IN AN AGREEMENT BETWEEN THE CORPORATION AND THE REGISTERED HOLDER, OR SUCH HOLDER’’S PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THIS CORPORATION.”

 18.3 “THE SHARES EVIDENCED BY THIS CERTIFICATE WERE ISSUED BY THE CORPORATION TO THE REGISTERED HOLDER UPON EXERCISE OF AN INCENTIVE
STOCK OPTION AS DEFINED IN SECTION 422 OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (“ISO”). IN ORDER TO OBTAIN THE PREFERENTIAL TAX TREATMENT AFFORDED TO ISOs, THE SHARES SHOULD NOT BE TRANSFERRED PRIOR TO 150869INSERT
DISQUALIFYING DISPOSITION DATE HERE]. SHOULD THE REGISTERED HOLDER ELECT TO TRANSFER ANY OF THE SHARES PRIOR TO THIS DATE AND FOREGO ISO TAX TREATMENT, THE TRANSFER AGENT FOR THE SHARES SHALL NOTIFY THE CORPORATION IMMEDIATELY. THE REGISTERED
HOLDER SHALL HOLD ALL SHARES PURCHASED UNDER THE INCENTIVE STOCK OPTION IN THE REGISTERED HOLDER’S NAME (AND NOT IN THE NAME OF ANY NOMINEE) PRIOR TO THIS DATE OR UNTIL TRANSFERRED AS DESCRIBED ABOVE.” 

19. LOCK-UP
AGREEMENT. 
 The Participant hereby agrees that in the event of any
underwritten public offering of stock, including an initial public offering of stock, made by the Company pursuant to an effective registration statement filed under the Securities Act, the Participant shall not offer, sell, contract to sell,
pledge, hypothecate, grant any option to purchase or make any short sale of, or otherwise dispose of any shares of stock of the Company or any rights to acquire stock of the Company for such period of time from and after the effective date of such
registration statement as may be established by the underwriter for such public offering; provided, however, that such period of time shall not exceed one hundred eighty (180) days from the effective date of the registration statement to be
filed in connection with such public offering; provided, further, however, that such one hundred eighty (180) day period may be extended for an additional period, not to exceed twenty (20) days, upon the request of the
Company or the underwriter to accommodate regulatory restrictions on (i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions, including but not limited to, the restrictions
contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor 

  
 18 

 
provisions or amendments thereto). The foregoing limitation shall not apply to shares registered in the public offering under the Securities Act. The Participant hereby agrees to enter into any
agreement reasonably required by the underwriters to implement the foregoing within a reasonable timeframe if so requested by the Company. 

20. RESTRICTIONS ON TRANSFER OF
SHARES. 
 At any time prior to the existence of a public market for the
Stock, the Board may prohibit the Participant and any transferee of such Participant from selling, transferring, assigning, pledging, or otherwise disposing of or encumbering any shares acquired pursuant to the Option (each, a
“Transfer”) without the prior written consent of the Board. The Board may withhold consent for any reason, including without limitation any Transfer (i) to any individual or entity identified by the Company
as a potential competitor or considered by the Company to be unfriendly, or (ii) if such Transfer increases the risk of the Company having a class of security held of record by such number of persons as would require the Company to register any
class of securities under the Exchange Act; or (iii) if such Transfer would result in the loss of any federal or state securities law exemption relied upon by the Company in connection with the initial issuance of such shares or the issuance of
any other securities; or (iv) if such Transfer is facilitated in any manner by any public posting, message board, trading portal, Internet site, or similar method of communication, including without limitation any trading portal or Internet
site intended to facilitate secondary transfers of securities; or (v) if such Transfer is to be effected in a brokered transaction; or (vi) if such Transfer would be of less than all of the shares of Stock then held by the stockholder and
its affiliates or is to be made to more than a single transferee. No shares acquired upon exercise of the Option may be sold, exchanged, transferred (including, without limitation, any transfer to a nominee or agent of the Participant), assigned,
pledged, hypothecated or otherwise disposed of, including by operation of law in any manner which violates any of the provisions of this Option Agreement, and, except pursuant to an Ownership Change Event, until the date on which such shares become
Vested Shares, and any such attempted disposition shall be void. The Company shall not be required (a) to transfer on its books any shares which will have been transferred in violation of any of the provisions set forth in this Option Agreement
or (b) to treat as owner of such shares or to accord the right to vote as such owner or to pay dividends to any transferee to whom such shares will have been so transferred. 

21. MISCELLANEOUS PROVISIONS. 

21.1 Termination or Amendment. The Board may terminate or amend the Plan or the Option at any time; provided, however, that except as
provided in Section 8 in connection with a Change in Control, no such termination or amendment may adversely affect the Option or any unexercised portion hereof without the consent of the Participant unless such termination or amendment is
necessary to comply with any applicable law or government regulation, including, but not limited to Section 409A of the Code. No amendment or addition to this Option Agreement shall be effective unless in writing. 

  
 19 

 21.2 Compliance with Section 409A. The Company intends that income
realized by the Participant pursuant to the Plan and this Option Agreement will not be subject to taxation under Section 409A of the Code. The provisions of the Plan and this Option Agreement shall be interpreted and construed in favor of
satisfying any applicable requirements of Section 409A of the Code. The Company, in its reasonable discretion, may amend (including retroactively) the Plan and this Agreement in order to conform to the applicable requirements of
Section 409A of the Code, including amendments to facilitate the Participant’s ability to avoid taxation under Section 409A of the Code. However, the preceding provisions shall not be construed as a guarantee by the Company of any
particular tax result for income realized by the Participant pursuant to the Plan or this Option Agreement. In any event, and except for the responsibilities of the Company set forth in Section 4.4, no Participating Company shall be
responsible for the payment of any applicable taxes incurred by the Participant on income realized by the Participant pursuant to the Plan or this Option Agreement. 

21.3 Further Instruments. The parties hereto agree to execute such further instruments and to take such further action as may reasonably
be necessary to carry out the intent of this Option Agreement. 
 21.4 Binding Effect. This Option Agreement shall inure to the
benefit of the successors and assigns of the Company and, subject to the restrictions on transfer set forth herein, be binding upon the Participant and the Participant’s heirs, executors, administrators, successors and assigns. 

21.5 Delivery of Documents and Notices. Any document relating to participation in the Plan, or any notice required or permitted
hereunder shall be given in writing and shall be deemed effectively given (except to the extent that this Option Agreement provides for effectiveness only upon actual receipt of such notice) upon personal delivery, electronic delivery at the e-mail address, if any, provided for the Participant by a Participating Company, or, upon deposit in the U.S. Post Office or foreign postal service, by registered or certified mail, or with a nationally recognized
overnight courier service, with postage and fees prepaid, addressed to the other party at the address of such party set forth in the Grant Notice or at such other address as such party may designate in writing from time to time to the other party.

 (a) Description of Electronic Delivery. The Plan documents, which may include but do not necessarily include: the
Plan, the Grant Notice, this Option Agreement, and any reports of the Company provided generally to the Company’s stockholders, may be delivered to the Participant electronically. In addition, if permitted by the Company, the Participant may
deliver electronically the Grant Notice and Exercise Notice called for by Section 4.2 to the Company or to such third party involved in administering the Plan as the Company may designate from time to time. Such means of electronic delivery may
include but do not necessarily include the delivery of a link to a Company intranet or the Internet site of a third party involved in administering the Plan, the delivery of the document via e-mail or such
other means of electronic delivery specified by the Company. 
 (b) Consent to Electronic Delivery. The Participant acknowledges that
the Participant has read Section 21.5(a) of this Option Agreement and consents to the electronic delivery of the Plan documents and, if permitted by the Company, the delivery of the Grant Notice, Exercise Notice and notices in connection with
the Escrow, as described in Section 21.5(a). The Participant acknowledges that he or she may receive from the Company a paper copy of any documents delivered electronically at no cost to the Participant by contacting

  
 20 

 
the Company by telephone or in writing. The Participant further acknowledges that the Participant will be provided with a paper copy of any documents if the attempted electronic delivery of such
documents fails. Similarly, the Participant understands that the Participant must provide the Company or any designated third party administrator with a paper copy of any documents if the attempted electronic delivery of such documents fails. The
Participant may revoke his or her consent to the electronic delivery of documents described in Section 21.5(a) or may change the electronic mail address to which such documents are to be delivered (if Participant has provided an electronic mail
address) at any time by notifying the Company of such revoked consent or revised e-mail address by telephone, postal service or electronic mail. Finally, the Participant understands that he or she is not
required to consent to electronic delivery of documents described in Section 21.5(a). 
 21.6 Integrated Agreement. The Grant
Notice, this Option Agreement and the Plan, together with any employment, service or other agreement with the Participant and a Participating Company referring to the Option, shall constitute the entire understanding and agreement of the Participant
and the Participating Company Group with respect to the subject matter contained herein or therein and supersede any prior agreements, understandings, restrictions, representations, or warranties among the Participant and the Participating Company
Group with respect to such subject matter. To the extent contemplated herein or therein, the provisions of the Grant Notice, the Option Agreement and the Plan shall survive any exercise of the Option and shall remain in full force and effect. 

21.7 Applicable Law. This Option Agreement shall be governed by the laws of the State of Texas as such laws are applied to agreements
between Texas residents entered into and to be performed entirely within the State of Texas. 
 21.8 Counterparts. The Grant Notice

 6. Notice of Disqualifying Disposition. If the Option is an Incentive Stock Option, I
agree that I will promptly notify the Chief Financial Officer of the Company if I transfer any of the Shares within one (1) year from the date I exercise all or part of the Option or within two (2) years of the Date of Grant. 

7. Binding Effect. I agree that the Shares are being acquired in accordance with and subject to the terms, provisions and
conditions of the Grant Notice, the Option Agreement, including the Unvested Share Repurchase Option, the Right of First Refusal, the Vested Share Repurchase Option and the Drag Along Rights set forth therein, and the Plan, to all of which I hereby
expressly assent. This Agreement shall inure to the benefit of and be binding upon my heirs, executors, administrators, successors and assigns. If required by the Company, I agree to deposit the certificate(s) evidencing the Shares, along with a
blank stock assignment separate from certificate executed by me, with an escrow agent designated by the Company, to be held pursuant to the escrow provisions contained in the Option Agreement. 

8. Transfer. I understand and acknowledge that the Shares have not been registered under the Securities Act of 1933, as
amended (the “Securities Act”), and that consequently the Shares must be held indefinitely unless they are subsequently registered under the Securities Act, an exemption from such registration is available, or
they are sold in accordance with Rule 144 or Rule 701 under the Securities Act. I further understand and acknowledge that the Company is under no obligation to register the Shares. I understand that the certificate or certificates
evidencing the Shares will be imprinted with legends which prohibit the transfer of the Shares unless they are registered or such registration is not required in the opinion of legal counsel satisfactory to the Company. 

9. Election Under Section 83(b) of the Code. I understand and acknowledge that if
I am exercising the Option to purchase Unvested Shares (i.e., shares that remain subject to the Company’s Unvested Share Repurchase Option), that I should consult with my tax advisor regarding the advisability of filing with the Internal
Revenue Service an election under Section 83(b) of the Code, which must be filed, if at all, no later than thirty (30) days after the date on which I exercise the Option. I acknowledge that I have been advised to consult with a tax advisor
prior to the exercise of the Option regarding the tax consequences to me of exercising the Option and filing or not filing an election under Section 83(b). AN ELECTION UNDER SECTION 83(b) MUST BE FILED, IF AT ALL, WITHIN 30 DAYS AFTER THE
DATE ON WHICH I PURCHASE SHARES. THIS TIME PERIOD CANNOT BE EXTENDED. I ACKNOWLEDGE THAT TIMELY FILING OF A SECTION 83(b) ELECTION, IF APPROPRIATE, IS MY SOLE RESPONSIBILITY, EVEN IF I REQUEST THE COMPANY OR ITS REPRESENTATIVES TO FILE SUCH
ELECTION ON MY BEHALF. 
 I am aware that Rule 144 under the Securities Act, which permits limited public resale of securities acquired
in a nonpublic offering, is not currently available with respect to the Shares and, in any event, is available only if certain conditions are satisfied. I understand that any sale of the Shares that might be made in reliance upon Rule 144 may
only be made in limited amounts in accordance with the terms and conditions of such rule and that a copy of Rule 144 will be delivered to me upon request.

 I understand that I am purchasing the Shares pursuant to the terms of the Plan, the Grant
Notice and my Option Agreement, copies of which I have received and carefully read and understand.

 BIGCOMMERCE HOLDINGS, INC. 

NOTICE OF GRANT OF STOCK OPTION 

(U.S. PARTICIPANT; IMMEDIATELY EXERCISABLE) 

The Participant has been granted an option (the “Option”) to purchase certain shares of Stock of BigCommerce Holdings,
Inc. pursuant to the BigCommerce Holdings, Inc. 2013 Stock Plan (the “Plan”), as follows: 
  

					
	Participant:	  	            
		
	Date of Grant:	  	            
		
	Number of Option Shares:	  	        , subject to adjustment as provided by the Option Agreement.
		
	Exercise Price:	  	$
		
	Initial Vesting Date:	  	
		
	Option Expiration Date:	  	The date ten (10) years after the Date of Grant
		
	Tax Status of Option:	  	 Stock Option.

		
	Vested Shares:	  	Except as provided in the Stock Option Agreement, the number of Vested Shares (disregarding any resulting fractional share) as of any date is determined by multiplying the Number of Option Shares by the
“Vested Ratio” determined as of such date as follows:
			
	 	  	 	  	Vested Ratio
			
		  	Prior to Initial Vesting Date	  	0
			
		  	On Initial Vesting Date, provided the Participant’s Service has not terminated prior to such date	  	1/4
			
		  	Plus	  	
			
		  	For each additional full month of the Participant’s continuous Service from Initial Vesting Date until the Vested Ratio equals 1/1, an additional	  	1/48

 The Exercise Price represents an amount the Company believes to be no less than the fair market value of a share of Stock as
of the Date of Grant, determined in good faith in compliance with the requirements of Section 409A of the Code. However, there is no guarantee that the Internal Revenue Service will agree with the Company’s determination. A subsequent IRS
determination that the Exercise Price is less than such fair market value could result in adverse tax consequences to the Participant. By signing below, the Participant agrees that the Company, its directors, officers and shareholders shall not be
held liable for any tax, penalty, interest or cost incurred by the Participant as a result of such determination by the IRS. The Participant is urged to consult with his or her own tax advisor regarding the tax consequences of the Option, including
the application of Section 409A. 
 By their signatures below, the Company and the Participant agree that the Option is governed by this Grant Notice
and by the provisions of the Plan and the Stock Option Agreement, both of which are attached to and made a part of this document. The Participant acknowledges receipt of copies of the Plan and the Stock Option Agreement, represents that the
Participant has read and is familiar with their provisions, and hereby accepts the Option subject to all of their terms and conditions.

3.2 No Monetary Payment Required. The Participant is not required to make any monetary payment (other than applicable tax withholding,
if any) as a condition to receiving the Units or Shares issued upon settlement of the Units, the consideration for which shall be past services actually rendered or future services to be rendered to the Participating Company Group or for its
benefit. Notwithstanding the foregoing, if required by applicable law, the Participant shall furnish consideration in the form of cash or past services rendered to the Participating Company Group or for its benefit having a value not less than the
par value of the Shares issued upon settlement of the Units. 

  
 2

purposes of determining the number of Vested Units following an Ownership Change Event, credited Service shall include all Service with any entity which is a member of the Participating Company Group at the time the Service is rendered, whether or
not such entity is a member of the Participating Company Group both before and after the Ownership Change Event.

Condition with respect to all or a portion of the Units. 
 5. SETTLEMENT OF THE
AWARD. 
 5.1 Issuance of Shares. Subject to the
provisions of Section 5.3 below, the Company shall issue one (1) Share to the Participant on the Settlement Date for each Vested Unit to be settled on such date. Shares issued in settlement of Units shall not be subject to any restriction
on transfer other than any such restriction as may be required pursuant to Section 5.3, Section 6 or the Company’s Trading Compliance Policy. 

5.2 Beneficial Ownership of Shares; Certificate Registration. The Participant hereby authorizes the Company, in its sole
discretion, to deposit any or all Shares acquired by the Participant pursuant to the settlement of the Award with the Company’s transfer agent, including any successor transfer agent, to be held in book entry form, or to deposit such Shares for
the benefit of the Participant with any broker with which the Participant has an account relationship of which the Company has notice. Except as provided by the foregoing, a certificate for the Shares acquired by the Participant shall be registered
in the name of the Participant, or, if applicable, in the names of the heirs of the Participant. 
 5.3 Restrictions on Grant of the Award
and Issuance of Shares. The grant of the Award and issuance of Shares upon settlement of the Award shall be subject to compliance with all applicable requirements of federal, state or foreign law with respect to such securities. No
Shares 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 Shares may then be 

  
 3 

 
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 securities subject to the Award shall relieve the Company of any liability in respect of the failure to issue such securities as to which such requisite authority shall not have been obtained. As a condition to the settlement of the
Award, the Company may require the Participant 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. 
 5.4 Fractional Shares. The Company shall not be required to issue fractional Shares upon
the settlement of the Award. 
 6. TAX WITHHOLDING.

 6.1 In General. At the time the Grant Notice is executed, or at any time thereafter as requested by a member of the Participating
Company Group, the Participant hereby authorizes withholding from payroll and any other amounts payable to the Participant, and otherwise agrees to make adequate provision for, any sums required to satisfy the federal, state, local and foreign tax
(including any social insurance) withholding obligations of the Participating Company Group, if any, which arise in connection with the Award, the vesting of Units or the issuance of Shares in settlement thereof. The Company shall have no obligation
to deliver Shares until the tax withholding obligations of the Participating Company Group have been satisfied by the Participant. 
 6.2
Assignment of Sale Proceeds. Subject to compliance with applicable law and the Company’s Trading Compliance Policy, if permitted by the Company, the Participant may satisfy the Participating Company Group’s tax withholding
obligations in accordance with procedures established by the Company providing for delivery by the Participant to the Company or a broker approved by the Company of properly executed instructions, in a form approved by the Company, providing for the
assignment to the Company of the proceeds of 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 have the right, but not the obligation, to require the Participant to satisfy all or any portion of the Participating Company Group’s tax withholding obligations by deducting from the Shares
otherwise deliverable to the Participant in settlement of the Award 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. 
 7. EFFECT
OF CHANGE IN CONTROL. 
 In
the event of a Change in Control, the treatment of the Award will be governed by Section 10 of the Plan and any applicable provisions of the Grant Notice. 

  
 4 

 8. RIGHT OF FIRST
REFUSAL. 
 8.1 Grant of Right of First Refusal. Except as provided
in Section 8.7, in the event the Participant, the Participant’s legal representative, or other holder of Shares acquired upon settlement of the Award proposes to sell, exchange, transfer, pledge, or otherwise dispose of any such Shares
(the “Transfer Shares”) to any person or entity, including, without limitation, any stockholder of a Participating Company, the Company shall have the right to repurchase the Transfer Shares under the terms and
subject to the conditions set forth in this Section (the “Right of First Refusal”). 
 8.2 Notice of
Proposed Transfer. Prior to any proposed transfer of the Transfer Shares, the Participant shall deliver written notice (the “Transfer Notice”) to the Company describing fully the proposed transfer, including
the number of Transfer Shares, the name and address of the proposed transferee (the “Proposed Transferee”) and, if the transfer is voluntary, the proposed transfer price, and containing such information
necessary to show the bona fide nature of the proposed transfer. In the event of a bona fide gift or involuntary transfer, the proposed transfer price shall be deemed to be the Fair Market Value of the Transfer Shares, as determined by the Board in
good faith. If the Participant proposes to transfer any Transfer Shares to more than one Proposed Transferee, the Participant shall provide a separate Transfer Notice for the proposed transfer to each Proposed Transferee. The Transfer Notice shall
be signed by both the Participant and the Proposed Transferee and must constitute a binding commitment of the Participant and the Proposed Transferee for the transfer of the Transfer Shares to the Proposed Transferee subject only to the Right of
First Refusal. 
 8.3 Bona Fide Transfer. If the Company determines that the information provided by the Participant in the Transfer
Notice is insufficient to establish the bona fide nature of a proposed voluntary transfer, the Company shall give the Participant written notice of the Participant’s failure to comply with the procedure described in this Section 8, and the
Participant shall have no right to transfer the Transfer Shares without first complying with the procedure described in this Section 8. The Participant shall not be permitted to transfer the Transfer Shares if the proposed transfer is not bona
fide. 
 8.4 Exercise of Right of First Refusal. If the Company determines the proposed transfer to be bona fide, the Company shall
have the right to purchase all, but not less than all, of the Transfer Shares (except as the Company and the Participant otherwise agree) at the purchase price and on the terms set forth in the Transfer Notice by delivery to the Participant of a
notice of exercise of the Right of First Refusal within thirty (30) days after the date the Transfer Notice is delivered to the Company. The Company’s exercise or failure to exercise the Right of First Refusal with respect to any proposed
transfer described in a Transfer Notice shall not affect the Company’s right to exercise the Right of First Refusal with respect to any proposed transfer described in any other Transfer Notice, whether or not such other Transfer Notice is
issued by the Participant or issued by a person other than the Participant with respect to a proposed transfer to the same Proposed Transferee. If the Company exercises the Right of First Refusal, the Company and the Participant shall thereupon
consummate the sale of the Transfer Shares to the Company on the terms set forth in the Transfer Notice within sixty (60) days after the date the Transfer Notice is delivered to the Company (unless a longer period is offered by the Proposed
Transferee); provided, however, that in the event the Transfer Notice provides for the 

  
 5 

 
payment for the Transfer Shares other than in cash, the Company shall have the option of paying for the Transfer Shares by the present value cash equivalent of the consideration described in the
Transfer Notice as reasonably determined by the Company. For purposes of the foregoing, cancellation of any indebtedness of the Participant to any member of the Participating Company Group shall be treated as payment to the Participant in cash to
the extent of the unpaid principal and any accrued interest canceled. Notwithstanding anything contained in this Section to the contrary, the period during which the Company may exercise the Right of First Refusal and consummate the purchase of the
Transfer Shares from the Participant shall terminate no sooner than the completion of a period of eight (8) months following the date on which the Participant acquired the Transfer Shares. 

8.5 Failure to Exercise Right of First Refusal. If the Company fails to exercise the Right of First Refusal in full (or to such lesser
extent as the Company and the Participant otherwise agree) within the period specified in Section 8.4, the Participant may conclude a transfer to the Proposed Transferee of the Transfer Shares on the terms and conditions described in the
Transfer Notice, provided such transfer occurs not later than ninety (90) days following delivery to the Company of the Transfer Notice or, if applicable, following the end of the period described in the last sentence of Section 8.4. The
Company shall have the right to demand further assurances from the Participant and the Proposed Transferee (in a form satisfactory to the Company) that the transfer of the Transfer Shares was actually carried out on the terms and conditions
described in the Transfer Notice. No Transfer Shares shall be transferred on the books of the Company until the Company has received such assurances, if so demanded, and has approved the proposed transfer as bona fide. Any proposed transfer on terms
and conditions different from those described in the Transfer Notice, as well as any subsequent proposed transfer by the Participant, shall again be subject to the Right of First Refusal and shall require compliance by the Participant with the
procedure described in this Section. 
 8.6 Transferees of Transfer Shares. All transferees of the Transfer Shares or any interest
therein, other than the Company, shall be required as a condition of such transfer to agree in writing (in a form satisfactory to the Company) that such transferee shall receive and hold such Transfer Shares or interest therein subject to all of the
terms and conditions of this Agreement, including this Section 8 providing for the Right of First Refusal with respect to any subsequent transfer. Any sale or transfer of any Shares shall be void unless the provisions of this Section are met.

 8.7 Transfers Not Subject to Right of First Refusal. The Right of First Refusal shall not apply to any transfer or exchange of the
Shares if such transfer or exchange is in connection with an Ownership Change Event. If the consideration received pursuant to such transfer or exchange consists of Shares of a member of the Participating Company Group, such consideration shall
remain subject to the Right of First Refusal unless the provisions of Section 8.9 result in a termination of the Right of First Refusal. 

8.8 Assignment of Right of First Refusal. The Company shall have the right to assign the Right of First Refusal at any time, whether or
not there has been an attempted transfer, to one or more persons as may be selected by the Company. 

  
 6 

 8.9 Early Termination of Right of First Refusal. The other provisions of this
Agreement notwithstanding, the Right of First Refusal shall terminate and be of no further force and effect upon the existence of a public market for the class of shares subject to the Right of First Refusal. A “public
market” shall be deemed to exist if (i) such shares are listed on a national securities exchange (as that term is used in the Exchange Act) or (ii) such shares are traded on the over-the-counter market and prices therefor are published daily on business days in a recognized financial journal. 

9. ADJUSTMENTS FOR CHANGES IN CAPITAL
STRUCTURE. 
 In the event of a change in the capital structure of the
Company, this Section 9 will be governed by Section 4.4 of the Plan. 
 10. RIGHTS AS
A STOCKHOLDER, DIRECTOR, EMPLOYEE OR CONSULTANT. 

The Participant shall have no rights as a stockholder with respect to any Shares which may be issued in settlement of this Award until the date
of the issuance of such Shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record
date is prior to the date the shares are issued, except as provided in Section 9. If the Participant is an employee, the Participant understands and acknowledges that, except as otherwise provided in a separate, written employment agreement
between a member of the Participating Company Group and the Participant, the Participant’s employment is “at will” and is for no specified term. Nothing in this Agreement shall confer upon the Participant any right to continue in the
Service of a member of the Participating Company Group or interfere in any way with any right of a member of the Participating Company Group to terminate the Participant’s Service at any time. 

11. LEGENDS. 

The Company may at any time place legends referencing the Right of First Refusal and any applicable federal, state or foreign securities law
restrictions on all certificates representing Shares issued pursuant to this Agreement. The Participant shall, at the request of the Company, promptly present to the Company any and all certificates representing Shares acquired pursuant to this
Award in the possession of the Participant in order to carry out the provisions of this Section. Unless otherwise specified by the Company, legends placed on such certificates may include, but shall not be limited to, the following: 

11.1 “THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN ACCORDANCE WITH RULE 144 OR RULE 701 UNDER THE ACT, OR THE COMPANY RECEIVES AN OPINION
OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.” 

  
 7 

 11.2 “THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON
TRANSFER AND REPURCHASE OPTIONS IN FAVOR OF THE CORPORATION OR ITS ASSIGNEE SET FORTH IN AN AGREEMENT BETWEEN THE CORPORATION AND THE REGISTERED HOLDER, OR SUCH HOLDER’S PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL
OFFICE OF THIS CORPORATION.” 
 12. COMPLIANCE WITH
SECTION 409A. 
 It is intended
that any election, payment or benefit which is made or provided pursuant to or in connection with this Award that may result in nonqualified deferred compensation within the meaning of Section 409A shall comply in all respects with the
applicable requirements of Section 409A (including applicable regulations or other administrative guidance thereunder, as determined by the Board in good faith) to avoid the unfavorable tax consequences provided therein for non-compliance and the Award shall be so construed. In connection with effecting such compliance with Section 409A, the following shall apply: 

12.1 Separation from Service; Required Delay in Payment to Specified Employee. Notwithstanding anything set forth herein to the
contrary, no amount payable pursuant to this Agreement on account of the Participant’s termination of Service which constitutes a “deferral of compensation” within the meaning of the Treasury Regulations issued pursuant to
Section 409A of the Code (the “Section 409A Regulations”) shall be paid unless and until the Participant has incurred a “separation from service” within the
meaning of the Section 409A Regulations. Furthermore, to the extent that the Participant is a “specified employee” within the meaning of the Section 409A Regulations as of the date of the Participant’s separation from
service, no amount that constitutes a deferral of compensation which is payable on account of the Participant’s separation from service shall be paid to the Participant before the date (the “Delayed Payment
Date”) which is the first day of the seventh month after the date of the Participant’s separation from service or, if earlier, the date of the Participant’s death following such separation from 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. 

12.2 Other Changes in Time of Payment. Neither the Participant nor the Company shall take any action to accelerate or delay the payment
of any benefits under this Agreement in any manner which would not be in compliance with the Section 409A Regulations. 
 12.3
Amendments to Comply with Section 409A; Indemnification. Notwithstanding any other provision of this Agreement to the contrary, the Company is authorized to amend this Agreement, to void or amend any election made by the
Participant under this Agreement and/or to delay the payment of any monies and/or provision of any benefits in such manner as may be determined by the Company, in its discretion, to be necessary or appropriate to comply with the Section 409A
Regulations without prior notice to or consent of the Participant. The Participant hereby releases and holds harmless the Company, its directors, officers and stockholders from any and all claims that may arise from or relate to any tax liability,
penalties, interest, costs, fees or other liability incurred by the Participant in connection with the Award, including as a result of the application of Section 409A. 

  
 8 

 12.4 Advice of Independent Tax Advisor. The Company has not obtained a tax ruling or
other confirmation from the Internal Revenue Service with regard to the application of Section 409A to the Award, and the Company does not represent or warrant that this Agreement will avoid adverse tax consequences to the Participant,
including as a result of the application of Section 409A to the Award. The Participant hereby acknowledges that he or she has been advised to seek the advice of his or her own independent tax advisor prior to entering into this Agreement and is
not relying upon any representations of the Company or any of its agents as to the effect of or the advisability of entering into this Agreement. 

13. LOCK-UP
AGREEMENT. 
 The Participant hereby agrees that in the event of any
underwritten public offering of Shares, including an initial public offering of Shares, made by the Company pursuant to an effective registration statement filed under the Securities Act, the Participant shall not offer, sell, contract to sell,
pledge, hypothecate, grant any option to purchase or make any short sale of, or otherwise dispose of any Shares of the Company or any rights to acquire Shares of the Company for such period of time from and after the effective date of such
registration statement as may be established by the underwriter for such public offering; provided, however, that such period of time may not exceed one hundred eighty (180) days from the effective date of the registration statement to be filed
in connection with such public offering; or, upon the request of the Company or the underwriter, such longer period as necessary to permit compliance with FINRA Rule 2241 or any successor provisions or amendments thereto. The foregoing limitation
will not apply to Shares registered in the public offering under the Securities Act. The Participant hereby agrees to enter into any agreement reasonably required by the underwriters to implement the foregoing within a reasonable timeframe if so
requested by the Company. 
 14. RESTRICTIONS ON TRANSFER OF
SHARES. 
 At any time prior to the existence of a public market for the
Shares, the Board may prohibit the Participant and any transferee of such Participant from selling, transferring, assigning, pledging, or otherwise disposing of or encumbering any Shares acquired pursuant to the Award (each, a
“Transfer”) without the prior written consent of the Board. The Board may withhold consent for any reason, including without limitation any Transfer (i) to any individual or entity identified by the Company
as a potential competitor or considered by the Company to be unfriendly, or (ii) if such Transfer increases the risk of the Company having a class of security held of record by such number of persons as would require the Company to register any
class of securities under the Exchange Act; or (iii) if such Transfer would result in the loss of any federal or state securities law exemption relied upon by the Company in connection with the initial issuance of such Shares or the issuance of
any other securities; or (iv) if such Transfer is facilitated in any manner by any public posting, message board, trading portal, Internet site, or similar method of communication, including without limitation any trading portal or Internet
site intended to facilitate secondary transfers of securities; or (v) if such Transfer is to be effected in a brokered transaction; or (vi) if such Transfer would be of less than all of the Shares then held by the stockholder and its
affiliates or is to be made to more than a single transferee. No Shares

acquired pursuant to this Award may be sold, exchanged, transferred (including, without limitation, any transfer to a nominee or agent of the Participant), assigned, pledged, hypothecated or
otherwise disposed of, including by operation of law in any manner which violates any of the provisions of this Agreement, and any such attempted disposition shall be void. The Company shall not be required (a) to transfer on its books any
Shares which will have been transferred in violation of any of the provisions set forth in this Agreement or (b) to treat as owner of such Shares or to accord the right to vote as such owner or to pay dividends to any transferee to whom such
Shares will have been so transferred. 
 15. MISCELLANEOUS
PROVISIONS. 
 15.1 Termination or Amendment. The Board may
terminate or amend the Plan or this Agreement at any time; provided, however, that except as provided in Section 7 in connection with a Change in Control, no such termination or amendment may have a materially adverse effect on the
Participant’s rights under this Agreement without the consent of the Participant unless such termination or amendment is necessary to comply with applicable law or government regulation, including, but not limited to, Section 409A. No
amendment or addition to this Agreement shall be effective unless in writing. 
 15.2 Nontransferability of the Award. Prior to the
issuance of Shares on the applicable Settlement Date, neither this Award nor any Units subject to this Award shall be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by
creditors of the Participant or the Participant’s beneficiary, except transfer by will or by the laws of descent and distribution and, for so long as the Company is relying on an order of the Securities and Exchange Commission (the
“SEC”) under Section 12(h) of the Exchange Act or a no-action position of the Staff of the SEC relieving the Company from registration under Section 12(g) of the
Exchange Act of the Units and the Shares subject thereto, the restrictions on transfer provided by Rule 12h-1(f) under the Exchange Act that would apply were the Units subject to such rule (including the
requirement under such rule that any permitted transferee may not further transfer the Units). No Units subject to this Award, or the Shares underlying such Units, shall, prior to the settlement of the Units, be subject to any short position,
“put equivalent position” or “call equivalent position” by the Participant, as such terms are defined in Rule 16a-1 under the Exchange Act, until the Company becomes subject to
Section 13 or Section 15(d) of the Exchange Act or is no longer relying on such SEC order or SEC Staff no action position. All rights with respect to the Award shall be exercisable during the Participant’s lifetime only by the
Participant or the Participant’s guardian or legal representative.
