(a) Requests for Registration. Subject to Section 2(e) below and the other terms and conditions of this
Agreement, commencing on the date that is one (1) year following the date hereof (or earlier if pursuant to Section 5.15 of the Merger Agreement or if authorized by the Company’s board of directors), each Holder may request
registration under the Securities Act of the resale of all or any portion of their Registrable Securities on Form S-1 or any similar long-form registration (“Long-Form Registrations”),
and each Holder may request registration under the Securities Act of the resale of all or any portion of their Registrable Securities on Form S-3 or any similar short-form registration (“Short-Form
Registrations”), if the Company is eligible to use such form. All registrations requested pursuant to this Section 2(a) are referred to herein as “Demand Registrations.” The Holder
making a Demand Registration may request that the registration be made pursuant to Rule 415 under the Securities Act (a “Shelf Registration”) and, if the Company is a WKSI at the time any request for a Demand Registration is
submitted to the Company, that such Shelf Registration be an automatic shelf registration statement (as defined in Rule 405 under the Securities Act) (an “Automatic Shelf Registration Statement”). Except to the

  
 5 

 
extent that Section 2(c) applies, promptly upon receipt of a request for a Demand Registration (but in no event more than five (5) Business Days thereafter), the
Company shall give written notice of the Demand Registration to all other Holders and, subject to the terms of Section 2(d), shall include in such Demand Registration (and in all related registrations and qualifications
under state blue sky laws and in any related underwriting) all Registrable Securities of each Holder with respect to which the Company has received a written request for inclusion therein within five (5) Business Days after the date the
Company’s notice was delivered. Notwithstanding the foregoing, other than delivery to each Holder of the written notice in accordance with this Section 2(a), the Company shall not be required to take any action that
would otherwise be required under this Section 2 if such action would violate Section 4(a) hereof or any similar provision contained in the underwriting agreement entered into in connection with
any underwritten Public Offering. 
 (b) Demand Registrations. The Holders, collectively as a group, shall be entitled to request no
more than three (3) Demand Registrations in which the Company shall pay all Registration Expenses, regardless of whether any registration statement is filed or any such Demand Registration is consummated. Demand Registrations shall be
Short-Form Registrations whenever the Company is permitted to use any applicable short form. At any time when the Company is eligible to use Form S-3 or another short form negotiation statement, the Company
shall use its reasonable best efforts to make Short-Form Registrations available for the sale of Registrable Securities. Notwithstanding anything in this Agreement to the contrary, the Company shall not be obligated to effect a Long-Form
Registration during any period in which it is permitted under the Securities Act to use Form S-3. 

(c) Shelf Registrations. 

(i) Subject to the availability of required financial information, as promptly as reasonably practicable, but in no event later
than forty-five (45) calendar days following the date of the closing of the Merger (the “Anticipated Filing Date”), the Company shall use its reasonable best efforts to file with the Securities and Exchange Commission a
registration statement under the Securities Act to permit the public resale of all of the Registerable Securities held by all Holders (and certain other equity securities of the Company) from time to time as permitted by Rule 415 under the
Securities Act (a “Shelf Registration Statement”). The Company, subject to Sections 2(d) and 8 hereof, shall include in such Shelf Registration (and in all related registrations and qualifications under state
blue sky laws) all Registrable Securities of each Holder; provided, however, that the Company shall not include in such Shelf Registration Statement the Registrable Securities of a Holder if (i) such Holder has provided notice to the
Company, no later than 15 calendar days after the closing of the Merger, that such Holder’s Registrable Securities shall not be included in such Shelf Registration Statement or (ii) the Company has not received such information reasonably
necessary about the Holder to include such Holder’s Registrable Securities in such Shelf Registration Statement, or has not received executed copies of documents reasonably requested by the Company in connection with such Shelf Registration
Statement, at least 10 calendar days before the Anticipated Filing Date (the “Shelf Registration Participation Deadline”). For the avoidance of doubt, the inclusion of a Holder’s Registerable Securities in the Shelf
Registration Statement and the effectiveness of such Shelf Registration shall not relieve any Holder of its obligations to comply with the restrictions contained in the Lock-Up Agreement, whether or not such

  
 6 

 
Shelf Registration Statement is declared effective prior to the expiration of the Lock-Up Term (as defined in the
Lock-Up Agreement). The Company shall use its reasonable best efforts to cause any Shelf Registration Statement to be declared effective under the Securities Act as soon as practicable after the initial filing
of such Shelf Registration Statement and, once effective, the Company shall use its reasonable best efforts to cause such Shelf Registration Statement to remain continuously effective, but for no time period longer than the period ending on the
earliest of (A) the date on which all Registrable Securities covered by such Shelf Registration Statement have been sold pursuant to the Shelf Registration Statement, (B) the date as of which there are no longer any Registrable Securities
covered by such Shelf Registration Statement in existence, and (C) the date on which all Registrable Securities are eligible to be sold in accordance with Rule 144 without regard to volume or manner of sale restrictions. Notwithstanding
anything to the contrary in Section 2(c)(ii), any Holder that is named as a selling securityholder in such Shelf Registration Statement may make a secondary resale under such Shelf Registration Statement without the consent
of the Holders representing a majority of the Registrable Securities or any other Holder if such resale does not require an amendment or a supplement to the Shelf Registration Statement. 

(ii) For so long as a Shelf Registration Statement is effective, the Holders shall have the right at any time or from time to
time to elect to offer and sell (including pursuant to an underwritten offering (an “Underwritten Takedown”)) Registrable Securities available for sale pursuant to such Shelf Registration Statement (“Shelf
Registrable Securities”) and the Company shall pay all Registration Expenses in connection therewith. The applicable Holders shall make such election by delivering to the Company a written request (a “Shelf Offering
Request”) for such offering (the “Shelf Offering”) specifying the number of Shelf Registrable Securities that such Holders desire to sell pursuant to such Shelf Offering. As promptly as practicable, but no later
than three (3) Business Days after receipt of a Shelf Offering Request, the Company shall give written notice (the “Shelf Offering Notice”) of such Shelf Offering Request to all other holders of Shelf Registrable
Securities. The Company, subject to Sections 2(d) and 8 hereof, shall include in such Shelf Offering (and in all related registrations and qualifications under state blue sky laws and in any related underwriting) the Shelf Registrable
Securities of any other Holder that shall have made a written request to the Company for inclusion in such Shelf Offering (which request shall specify the maximum number of Shelf Registrable Securities intended to be sold by such Holder in the Shelf
Offering) within two (2) Business Days after the receipt of the Shelf Offering Notice. The Company shall, as expeditiously as possible (and in any event within ten (10) days after the receipt of a Shelf Offering Request, unless a longer
period is agreed to by the Holders that made the Shelf Offering Request), use its reasonable best efforts to facilitate such Shelf Offering. 

(iii) If the Holders wish to engage in an underwritten block trade, variable price reoffer or overnight underwritten offering,
in each case, by means of a Shelf Registration Statement (either through filing an Automatic Shelf Registration Statement or through a take-down from an already existing Shelf Registration Statement), then, notwithstanding the time periods set forth
in Section 2(c)(ii), such holders shall notify the Company not less than two (2) Business Days prior to the day such Shelf Offering is to 

  
 7 

 
commence. The Company shall promptly notify other Holders of such Shelf Offering, and such other Holders must elect whether or not to participate by the next Business Day (i.e., one
(1) Business Day prior to the day such Shelf Offering is scheduled to commence) (unless a longer period is agreed to by the holders of a majority of the Registrable Securities wishing to engage in the underwritten block trade), and the Company
shall as expeditiously as possible use its reasonable best efforts to facilitate such Shelf Offering (which may close as early as two (2) Business Days after the date it commences); provided that the Holders shall use commercially
reasonable efforts to work with the Company and the managing underwriters prior to making such request in order to facilitate preparation of the registration statement, prospectus and other offering documentation related to the Shelf Offering. 

(iv) The Company shall, at the request of Holders representing a majority of the Registrable Securities covered by a Shelf
Registration Statement, file any prospectus supplement or, if the applicable Shelf Registration Statement is an Automatic Shelf Registration Statement, any post-effective amendments and otherwise take any action necessary to include therein all
disclosure and language deemed necessary or advisable by such the Company to effect such Shelf Offering. 
 (d) Priority on Demand
Registrations and Shelf Offerings. The Company shall not include in any Demand Registration or Shelf Offering any securities that are not Registrable Securities without the prior written consent of Holders representing a majority of the
Registrable Securities included in such registration or offering. If a Demand Registration or a Shelf Offering is an underwritten offering and the managing underwriters advise the Company that in their opinion the number of securities requested to
be included in such Shelf Offering exceeds the number of securities that can be sold in such Shelf Offering without adversely affecting the marketability, proposed offering price, timing or method of distribution of the Shelf Offering, the Company
shall include in such registration or offering, as applicable, prior to the inclusion of any securities which are not Registrable Securities, the number of Registrable Securities requested by Holders to be included that, in the opinion of such
underwriters, can be sold without any such adverse effect, pro rata among the respective Holders thereof on the basis of the amount of Registrable Securities then owned by each such Holder that such Holder of Registrable Securities shall have
requested to be included therein. Alternatively, if the number of Registrable Securities which can be included on a Shelf Registration Statement is otherwise limited by Instruction I.B.6 to Form S-3 (or any
successor provision thereto), the Company shall include in such registration or offering, prior to the inclusion of any securities which are not Registrable Securities, the number of Registrable Securities requested to be included which can be
included on such Shelf Registration Statement in accordance with the requirements of Form S-3, pro rata among the respective Holders thereof on the basis of the amount of Registrable Securities owned by each
such Holder that such Holder of Registrable Securities shall have requested to be included therein. 

  
 8 

 (e) Restrictions on Demand Registration and Shelf Offerings. 

(i) The Company shall not be obligated to effect more than two (2) Demand Registrations in any calendar year, nor shall
the Company be obligated to effect a Demand Registration within ninety (90) days of a previous Demand Registration or a previous registration statement in which Registrable Securities were included and in which there was no reduction in the
number of Registrable securities requested to be included. The Company may postpone, for up to sixty (60) days from the date of any request, the filing or the effectiveness of a registration statement for a Demand Registration or suspend the
use of a prospectus that is part of a Shelf Registration Statement for up to sixty (60) days from the date of the Suspension Notice (as defined below) and therefore suspend sales of the Shelf Registrable Securities (such period, the
“Suspension Period”) by providing written notice to the Holders if (A) the Company determines in its reasonable good faith judgment that the offer or sale of Registrable Securities would reasonably be expected to have a
material adverse effect on any proposal or plan by the Company or any Subsidiary to engage in any material acquisition of assets or stock (other than in the ordinary course of business) or any material merger, consolidation, tender offer,
recapitalization, reorganization or other transaction involving the Company or any Subsidiary, or (B) upon advice of counsel, the sale of Registrable Securities pursuant to the registration statement would require disclosure of MNPI not
otherwise required to be disclosed under applicable law, and either (x) the Company has a bona fide business purpose for preserving the confidentiality of such transaction or (y) disclosure of such MNPI would have a material adverse effect
on the Company or the Company’s ability to consummate such transaction; provided that in such event, the Holders shall be entitled to withdraw such request for a Demand Registration or underwritten Shelf Offering and the Company shall
pay all Registration Expenses in connection with such Demand Registration or Shelf Offering. The Company may delay a Demand Registration hereunder only once in any twelve (12)-month period, except with the consent of the applicable Holders. 

(ii) In the case of an event that causes the Company to suspend the use of a Shelf Registration Statement as set forth in
paragraph (e)(i) above or pursuant to applicable subsections of Section 5(a)(vi) (a “Suspension Event”), the Company shall give a notice to the Holders of Registrable Securities registered for
resale pursuant to such Shelf Registration Statement (a “Suspension Notice”) to suspend sales of the Registrable Securities and such notice shall state generally the basis for the notice and that such suspension shall
continue only for so long as the Suspension Event or its effect is continuing. If the basis of such suspension is nondisclosure of MNPI, the Company shall not be required to disclose the subject matter of such MNPI to Holders. A Holder shall not
effect any sales of the Registrable Securities pursuant to such Shelf Registration Statement (or such filings) at any time after it has received a Suspension Notice from the Company and prior to receipt of an End of Suspension Notice (as defined
below). Each Holder agrees that it shall treat as confidential the receipt of the Suspension Notice and shall not disclose the existence of such Suspension Notice or use the information contained in such Suspension Notice without the prior consent
of the Company until such time as the information contained therein is or becomes available to the public generally, other than as a result of disclosure by a Holder in breach of the terms of this Agreement. Holders may recommence effecting sales of
the Registrable Securities pursuant to the Shelf Registration Statement (or such filings) following written notice to such effect (an “End of Suspension Notice”) from the Company, which End of Suspension Notice shall be given
by the Company to the Holders promptly following the conclusion of any Suspension Event. 

  
 9 

 (iii) Notwithstanding any provision herein to the contrary, if the Company
gives a Suspension Notice with respect to any Shelf Registration Statement pursuant to this Section 2(e), the Company agrees that it shall extend the period of time during which such Shelf Registration Statement shall be
maintained effective pursuant to this Agreement by the number of days during the period from the date of receipt by the holders of the Suspension Notice to and including the date of receipt by the holders of the End of Suspension Notice and provide
copies of any supplemented or amended prospectus necessary to resume sales, with respect to each Suspension Event. 
 (f) Selection of
Underwriters. Holders representing a majority of the Registrable Securities included in any Demand Registration or Underwritten Takedown shall have the right to select the investment banker(s) for such offering (including assignment of roles).
If any Shelf Offering is an underwritten offering, the Holders holding a majority of the Registrable Securities participating in such underwritten offering shall have the right to select the investment banker(s) for the offering relating to such
Shelf Offering (including assignment of roles). The Company represents and warrants that no investment bankers are entitled to any rights that would conflict with the rights of the Holders under this Section 2. 

(g) Other Registration Rights. The Company represents and warrants that, after giving effect to the termination of the Prior Agreement
pursuant to Section 13, it is not a party to, or otherwise subject to, any other agreement granting registration rights to any other Person with respect to any securities of the Company. Except as provided in this
Agreement, the Company shall not grant to any Persons the right to request the Company or any Subsidiary to register any Capital Stock of the Company or of any Subsidiary, or any securities convertible or exchangeable into or exercisable for such
securities, without the prior written consent of the Controlling Holders; provided that the Company may grant rights to other Persons to participate in Piggyback Registrations so long as such rights are subordinate to the rights of the Holders with
respect to such Piggyback Registrations as set forth below. 
 (h) Revocation of Demand Notice or Shelf Offering Notice. At any time
prior to the effective date of the registration statement relating to a Demand Registration or the “pricing” of any Shelf Offering, the Holders that provided such Demand Registration or Shelf Offering Notice may revoke such Demand
Registration or Shelf Offering Notice on behalf of all Holders participating in such Demand Registration or Shelf Offering without liability to such Holders, in each case by providing written notice to the Company.

(i) pursuant to a Demand Registration, (ii) in connection with registrations on Form S-4 or S-8 promulgated by the Securities and Exchange Commission or any
successor or similar forms or (iii) a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of Registrable Securities) and the
registration form to be used may be used for the registration of the resale of Registrable Securities (a “Piggyback  

  
 10 

 
Registration”), the Company shall give prompt written notice (in any event within two (2) Business Days after its receipt of notice of any request for registration on
behalf of holders of the Company’s securities (other than under this Agreement)) to all Holders of its intention to effect such Piggyback Registration and, subject to the terms of Section 3(c) and
Section 3(d), shall include in such Piggyback Registration (and in all related registrations or qualifications under blue sky laws and in any related underwriting) all Registrable Securities of each Holder with respect to

requested to be included in such registration which, in the opinion of the underwriters, can be sold without any such adverse effect, pro rata among the Holders on the basis of the number of Registrable Securities then owned by each such Holder that
such Holder of Registrable Securities shall have requested to be included therein, (ii) second, the securities requested to be included therein by the initial holders requesting such registration which, in the opinion of the underwriters, can
be sold without any such adverse effect and (iii) third, other securities requested to be included in such registration which, in the opinion of the underwriters, can be sold without any such adverse effect.

sell, contract to sell, pledge or otherwise dispose of (including sales pursuant to Rule 144), directly or indirectly, any Capital Stock of the Company (including Capital Stock of the Company that may be deemed to be owned beneficially by such
holder in accordance with the rules and regulations of the Securities and Exchange Commission) (collectively, “Securities”), (ii) enter into a transaction which would have the same effect as described in clause
(i) above, (iii) enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences or ownership of any Securities, whether such transaction is to be settled by delivery of such
Securities, in cash or otherwise (each of (i), (ii) and (iii) above, a “Sale Transaction”), or (iv) publicly disclose the intention to enter into any Sale Transaction, commencing on the earlier of the
date on which the Company gives notice to the Holders that a preliminary prospectus has been circulated for such Public Offering or the “pricing” of such offering and continuing to the date that is ninety (90) days following the date
of the final prospectus for such Public Offering (or such shorter period that is required by the managing underwriter(s)) (the “Holdback Period”). 

(b) Exceptions. The foregoing holdback agreements in Section 4(a) shall not apply to a registration on Form S-8 or any successor or similar form or otherwise in connection with an employee benefit plan or in connection with any registration on Form S-4 or any successor or similar
form in connection with any type of acquisition transaction or exchange offer. 
 (c) The Company. The Company (i) shall not file
any registration statement for a Public Offering or cause any such registration statement to become effective, or effect any public sale or distribution of its equity securities, or any securities, options or rights convertible into or exchangeable
or exercisable for such securities, during any Holdback Period without the consent of Holders representing a majority of the Registrable Securities and (ii) shall use its reasonable best efforts to cause (A) each holder of at least five
percent (5%) (on a fully-diluted basis) of its shares of Common Stock, or any securities convertible into or exchangeable or exercisable for at least five percent (5%) (on a fully diluted basis) of its shares of Common Stock, and (B) each of
its directors and executive officers, to agree not to effect any Sale Transaction during any Holdback Period, except as part of such underwritten registration, if otherwise permitted, unless the managing underwriter(s) for such Public Offering
otherwise agree in writing. 
 Section 5. Registration Procedures. 

(a) Whenever the Holders have requested that any Registrable Securities be registered for resale pursuant to this Agreement or have initiated a
Shelf Offering, the Company shall use its reasonable best efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof, and pursuant thereto the Company shall as
expeditiously as reasonably practicable: 

  
 12 

 (i) in accordance with the Securities Act and all applicable rules and
regulations promulgated thereunder, prepare and file with the Securities and Exchange Commission a registration statement, and all amendments and supplements thereto and related prospectuses with respect to such Registrable Securities and use its
reasonable best efforts to cause such registration statement to become effective (provided that before filing a registration statement or prospectus or any amendments or supplements thereto, the Company shall furnish to the counsel selected by the
Holders representing a majority of the Registrable Securities covered by such registration statement copies of all such documents proposed to be filed, which documents shall be subject to review by such counsel); 

(ii) notify each Holder of (A) the issuance by the Securities and Exchange Commission of any stop order suspending the
effectiveness of any registration statement or the initiation of any proceedings for that purpose, (B) the receipt by the Company or its counsel of any notification with respect to the suspension of the qualification of the Registrable
Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose and (C) the effectiveness of each registration statement filed hereunder; 

(iii) prepare and file with the Securities and Exchange Commission such amendments and supplements to such registration
statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for a period ending when all of the securities covered by such registration statement have been disposed of in accordance
with the intended methods of distribution by the sellers thereof set forth in the prospectus included in such registration statement (but in any event not before the expiration of any longer period required under the Securities Act or, if such
registration statement relates to an underwritten Public Offering, such longer period as in the opinion of counsel for the underwriters a prospectus is required by law to be delivered in connection with sale of Registrable Securities by an
underwriter or dealer) and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement during such period in accordance with the intended methods of disposition by the
sellers thereof set forth in the prospectus included in such registration statement; 
 (iv) furnish to each seller of
Registrable Securities thereunder such number of copies of such registration statement, each amendment and supplement thereto, the prospectus included in such registration statement (including each preliminary prospectus), each Free Writing
Prospectus and such other documents as such seller may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller; 

  
 13 

 (v) if applicable, use reasonable best efforts to register or qualify such
Registrable Securities under such other securities or blue sky laws of such jurisdictions as any seller reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate
the disposition in such jurisdictions of the Registrable Securities owned by such seller (provided that the Company shall not be required to (A) qualify generally to do business in any jurisdiction where it would not otherwise be required to
qualify but for this subparagraph or (B) subject itself to taxation in any such jurisdiction); 
 (vi) notify each
seller of such Registrable Securities (A) promptly after it receives notice thereof, of the date and time when such registration statement and each post-effective amendment thereto has become effective or a prospectus or supplement to any
prospectus relating to a registration statement has been filed and when any registration or qualification has become effective under a state securities or blue sky law or any exemption thereunder has been obtained, (B) promptly after receipt
thereof, of any written comments by the Securities and Exchange Commission, or any request by the Securities and Exchange Commission or other federal or state governmental authority for amendments or supplements to such registration statement or
such prospectus, or for additional information (whether before or after the effective date of the registration statement) or any other correspondence with the Securities and Exchange Commission relating to, or which may affect, the registration and
(C) at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in such registration statement contains an untrue statement of a
material fact or omits any fact necessary to make the statements therein not misleading, and, subject to Section 2(e), at the request of any such seller, the Company shall use its best efforts to prepare a supplement or
amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not contain an untrue statement of a material fact or omit to state any fact necessary to make the statements
therein not misleading; 
 (vii) use reasonable best efforts to cause all such Registrable Securities to be listed on each
securities exchange on which similar securities issued by the Company are then listed and, if not so listed, to be listed on a securities exchange and, without limiting the generality of the foregoing, to arrange for at least two (2) market
makers to register as such with respect to such Registrable Securities with FINRA; 
 (viii) use reasonable best efforts to
provide a transfer agent, registrar and CUSIP number for all such Registrable Securities not later than the effective date of such registration statement; 

(ix) enter into and perform such customary agreements (including underwriting agreements in customary form), which may include
indemnification provisions in favor of underwriters and other Persons in addition to the provisions of Section 7 hereof, make such representations and warranties to the Holders registering the resale of securities and the
underwriters or agents, if any, in form, substance and scope as are customarily made by issuers in underwritten public offerings similar to the offering then being undertaken, and take all such other actions as the Holders representing a majority of
the Registrable Securities being sold or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities; 

  
 14 

 (x) make available for inspection by any seller of Registrable Securities,
any underwriter participating in any disposition pursuant to such registration statement and any attorney, accountant or other agent retained by any such seller or underwriter, all financial and other records, pertinent corporate and business
documents and properties of the Company as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause the Company’s officers, directors, employees, agents, representatives and independent accountants
to make themselves available to discuss the business of the Company and to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such registration statement; 

(xi) use reasonable best efforts to ensure that any Free Writing Prospectus utilized in connection with any Demand Registration
or Piggyback Registration hereunder complies in all material respects with the Securities Act, is filed in accordance with the Securities Act to the extent required thereby, is retained in accordance with the Securities Act to the extent required
thereby and, when taken together with the related prospectus, shall not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were
made, not misleading; 
 (xii) otherwise use reasonable best efforts to comply with all applicable rules and regulations of
the Securities and Exchange Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve months beginning with the first day of the Company’s first full
calendar quarter after the effective date of the registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158; 

(xiii) to the extent that a Holder, in its reasonable judgment, might be deemed to be an underwriter of any Registrable
Securities or a controlling person of the Company, permit such Holder to participate in the preparation of such registration or comparable statement and allow such Holder to provide language for insertion therein, in form and substance reasonably
satisfactory to the Company, which in the reasonable judgment of such Holder and its counsel should be included; 
 (xiv) in
the event of the issuance of any stop order suspending the effectiveness of a registration statement, or the issuance of any order suspending or preventing the use of any related prospectus or suspending the qualification of any Common Stock
included in such registration statement for sale in any jurisdiction, use reasonable best efforts promptly to obtain the withdrawal of such order; 

(xv) use reasonable best efforts to cause such Registrable Securities covered by such registration statement to be registered
with or approved by such other governmental agencies or authorities as may be necessary to enable the sellers thereof to consummate the disposition of such Registrable Securities; 

  
 15 

 (xvi) cooperate with the Holders of Registrable Securities covered by such
registration statement and the managing underwriter(s) or agent(s), if any, to facilitate the timely preparation and delivery of book entry evidence or certificates (not bearing any restrictive legends) representing the Registrable Securities to be
sold under the registration statement and enable such Registrable Securities to be in such denominations and registered in such names as the managing underwriter, or agent, if any, or such Holders may request; 

(xvii) cooperate with each Holder of Registrable Securities covered by such registration statement and each underwriter or
agent participating in the disposition of such Registrable Securities and their respective counsel in connection with any filings required to be made with FINRA; 

(xviii) use reasonable best efforts to make available the executive officers of the Company to participate with the Holders of
Registrable Securities covered by such registration statement and any underwriters in any “road shows” or other selling efforts that may be reasonably requested by the Holders in connection with the methods of distribution for the
Registrable Securities; 
 (xix) in the case of any underwritten Public Offering, use its reasonable best efforts to obtain
one or more comfort letters from the Company’s independent certified public accountants (and, if necessary, any other independent certified public accountants or independent auditors of any Subsidiary of the Company or any business acquired by
the Company for which financial statements and financial data are, or are required to be, included in the registration statement) in customary form and covering such matters of the type customarily covered by comfort letters as the Holders
representing a majority of the Registrable Securities being sold reasonably request; 
 (xx) in the case of any underwritten
Public Offering, use its reasonable best efforts to provide a legal opinion of the Company’s outside counsel, dated the date of the closing under the underwriting agreement in customary form and covering such matters of the type customarily
covered by legal opinions of such nature, which opinion shall be addressed to the underwriters and the Holders of such Registrable Securities being sold; 

(xxi) if the Company files an Automatic Shelf Registration Statement covering any Registrable Securities, use its reasonable
best efforts to remain a WKSI (and not become an ineligible issuer (as defined in Rule 405 under the Securities Act)) during the period during which such Automatic Shelf Registration Statement is required to remain effective and, if WKSI status is
lost, to file an amendment to the Automatic Shelf Registration Statement to convert it into a form on which the Company is then permitted to use to register the resale of securities; 

(xxii) if the Company does not pay the filing fee covering the Registrable Securities at the time an Automatic Shelf
Registration Statement is filed, pay such fee at such time or times as the Registrable Securities are to be sold; 

  
 16 

 (xxiii) if an Automatic Shelf Registration Statement has been outstanding
for at least three (3) years, at the end of the third year, file a new Automatic Shelf Registration Statement covering the Registrable Securities, and, if at any time when the Company is required to
re-evaluate its WKSI status the Company determines that it is not a WKSI, use its reasonable best efforts to refile the Shelf Registration Statement on Form S-3 and, if
such form is not available, Form S-1 and keep such registration statement effective during the period during which such registration statement is required to be kept effective in accordance with this
Agreement; 
 (xxiv) provide all such other certificates, letters, opinions and other requested documents customarily
provided in public offerings similar to the offering then being undertaken; and 
 (xxv) take all such other reasonable
actions as are reasonably necessary or advisable in order to expedite or facilitate the disposition of such Registrable Securities in accordance with the terms of this Agreement. 

(b) If the Company files any Automatic Shelf Registration Statement for the benefit of the holders of any of its securities other than the
Holders, and the Holders do not request that their Registrable Securities be included in such Shelf Registration Statement, the Company agrees that, once it is eligible to rely on Rule 430B, at the request of the Holders holding a majority of the
Registrable Securities, it shall include in such Automatic Shelf Registration Statement such disclosures as may be required by Rule 430B in order to ensure that the Holders’ Registrable Securities may be added to such Shelf Registration
Statement at a later time through the filing of a prospectus supplement rather than a post-effective amendment. 
 (c) Any officer of the
Company who is a Holder agrees that if and for so long as he or she is employed by the Company or any Subsidiary thereof, he or she shall participate in the sale process in a manner customary and reasonable for persons in like positions and
consistent with his or her other duties with the Company and in accordance with applicable law, including the preparation of the registration statement and the preparation and presentation of any road shows. 

(d) The Company may require each Holder requesting, or electing to participate in, any registration to furnish the Company such information
regarding such Holder and the intended method(s) of distribution of such Registrable Securities as the Company may from time to time reasonably request in writing. 

Section 6. Registration Expenses. 

(a) The Company’s Obligation. All expenses incident to the Company’s performance of or compliance with this Agreement
(including, without limitation, (i) all registration, qualification and filing fees (including filings with the Securities and Exchange Commission and FINRA and the reasonable fees and disbursements of counsel for the underwriters in connection
with FINRA qualification of the Registrable Securities) (which shall not exceed $10,000 for each public offering, unless otherwise agreed by the Company), (ii) fees and expenses of compliance with securities or blue sky laws (including
reasonable fees and disbursements of counsel for the underwriters in connection with blue sky qualification of the Registrable Securities) (which shall not exceed $10,000 for each public offering, unless otherwise agreed by the Company),
(iii) printing expenses (including expenses of printing certificates (if any) for Registrable 

  
 17 

 
Securities in a form eligible for deposit with The Depositary Trust Company and of printing prospectuses if the printing of prospectuses is requested by the managing underwriter(s) or by the
Holders representing a majority of the Registrable Securities included in such registration), (iv) messenger, telephone and delivery expenses, (v) fees and disbursements of custodians, (vi) any other reasonable fees and disbursements
of underwriters customarily paid by issuers or sellers of securities (excluding underwriting discounts and commissions), (vii) fees and expenses of the transfer agent and registrar of the Company’s Common Stock and (viii) fees and
disbursements of counsel for the Company and all independent certified public accountants (including the expenses of any special audit and comfort letters required by or incident to such performance) and other Persons retained by the Company) (all
such expenses being herein called “Registration Expenses”), shall be borne by the Company, and the Company shall, in any event, pay its internal expenses (including, without limitation, all salaries and expenses of its
officers and employees performing legal or accounting duties), the expense of any annual audit or quarterly review, the expense of any liability insurance and the expenses and fees for listing the securities to be registered on each securities
exchange on which similar securities issued by the Company are then listed or quotation of the Registrable Securities on any inter-dealer quotation system. Each Person that sells securities pursuant to a Demand Registration or Piggyback Registration
hereunder shall bear and pay all underwriting discounts and commissions applicable to the securities sold for such Person’s account. 

(b) Counsel Fees and Disbursements. In connection with each Demand Registration, each Piggyback Registration and each Shelf Offering
that is an underwritten Public Offering, the Company shall reimburse the Holders of Registrable Securities included in such registration for the reasonable fees and disbursements of (i) one counsel chosen by the Holders representing a majority
of the Registrable Securities included in such registration and (ii) each additional counsel retained by any Holder for the purpose of rendering an opinion on behalf of such Holder in connection with any Demand Registration, Piggyback
Registration or Shelf Offering that is an underwritten Public Offering, but only to the extent that counsel referred to in clause (i) is unable or unwilling to render an opinion on behalf of such Holder. 

(c) Security Holders. To the extent any expenses are not required to be paid by the Company, each holder of securities included in any
registration hereunder shall pay those expenses allocable to the registration of such Holder’s securities so included in proportion to the aggregate selling price of the securities to be so registered. 

Section 7. Indemnification and Contribution. 

(a) By the Company. The Company shall indemnify and hold harmless, to the extent permitted by law, each Holder, such Holder’s
officers, directors, managers, employees, agents, brokers, dealers and representatives, and each Person who controls such Holder (within the meaning of the Securities Act) (the “Holder Indemnified Parties”)
against all losses, claims, actions, damages, liabilities and expenses (including with respect to actions or proceedings, whether commenced or threatened, and including reasonable attorney fees and expenses) caused by, resulting from, arising out
of, based upon or related to any of the following statements, omissions or violations (each a “Violation”) by the Company: (i) any untrue or alleged untrue statement of material fact contained in (A) any
registration statement, prospectus, preliminary prospectus or Free Writing Prospectus, or any amendment thereof or supplement thereto or (B) any 

  
 18 

 
application or other document or communication (in this Section 7, collectively called an “application”) executed by or on behalf of the Company
or based upon written information furnished by or on behalf of the Company filed in any jurisdiction in order to qualify any securities covered by such registration under the securities laws thereof, (ii) any omission or alleged omission of a
material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) any violation or alleged violation by the Company of the Securities Act or any other similar federal or state securities laws or any
rule or regulation promulgated thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance. In addition, the Company will reimburse such Holder
Indemnified Party for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such losses. Notwithstanding the foregoing, the Company shall not be liable in any such case to the extent that any
such losses result from, arise out of, are based upon, or relate to an untrue statement or alleged untrue statement, or omission or alleged omission, made in such registration statement, any such prospectus, preliminary prospectus or Free Writing
Prospectus or any amendment or supplement thereto, or in any application, in reliance upon, and in conformity with, written information prepared and furnished in writing to the Company by such Holder Indemnified Party expressly for use therein or by
such Holder Indemnified Party’s failure to deliver a copy of the registration statement or prospectus or any amendments or supplements thereto after the Company has furnished such Holder Indemnified Party with a sufficient number of copies of
the same. In connection with an underwritten offering, the Company shall indemnify such underwriters, their officers and directors, and each Person who controls such underwriters (within the meaning of the Securities Act) to the same extent as
provided above with respect to the indemnification of the Holder Indemnified Parties. 
 (b) By Each Holder. In connection with any
registration statement in which a Holder is participating, each such Holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such registration statement or
prospectus and, to the extent permitted by law, shall indemnify the Company, its officers, directors, managers, employees, agents and representatives, and each Person who controls the Company (within the meaning of the Securities Act) against any
losses, claims, damages, liabilities and expenses resulting from any untrue or alleged untrue statement of material fact contained in the registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or
any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit
so furnished in writing by such Holder expressly for use in such registration statement; provided that the obligation to indemnify shall be individual, not joint and several, for each Holder and shall be limited to the net amount of proceeds
received by such Holder from the sale of Registrable Securities pursuant to such registration statement. 
 (c) Claim Procedure. Any
Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall impair any
Person’s right to indemnification hereunder only to the extent such failure has prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and
indemnifying parties may exist with respect to such claim, permit such 

  
 19 

 
indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to
any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld, conditioned or delayed). An indemnifying party who is not entitled to, or elects not to, assume the defense of a
claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest
may exist between such indemnified party and any other of such indemnified parties with respect to such claim. In such instance, the conflicted indemnified parties shall have a right to retain one separate counsel, chosen by the Holders representing
a majority of the Registrable Securities included in the registration if such Holders are indemnified parties, at the expense of the indemnifying party. 

(d) Contribution. If the indemnification provided for in this Section 7 is held by a court of competent
jurisdiction to be unavailable to, or is insufficient to hold harmless, an indemnified party or is otherwise unenforceable with respect to any loss, claim, damage, liability or action referred to herein, then the indemnifying party shall contribute
to the amounts paid or payable by such indemnified party as a result of such loss, claim, damage, liability or action in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified
party on the other hand in connection with the statements or omissions which resulted in such loss, claim, damage, liability or action as well as any other relevant equitable considerations; provided that the maximum amount of liability in respect
of such contribution shall be limited, in the case of each seller of Registrable Securities, to an amount equal to the net proceeds actually received by such seller from the sale of Registrable Securities effected pursuant to such registration. The
relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to
information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it
would not be just or equitable if the contribution pursuant to this Section 7(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account such equitable
considerations. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or expenses referred to herein shall be deemed to include any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending against any action or claim which is the subject hereof. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who is not guilty of such fraudulent misrepresentation. 
 (e) Release. No indemnifying party shall,
except with the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement that does not include as an unconditional term thereof giving by the claimant or plaintiff to such indemnified party of a release
from all liability in respect to such claim or litigation. Notwithstanding anything to the contrary in this Section 7, an indemnifying party shall not be liable for any amounts paid in settlement of any loss, claim, damage,
liability, or action if such settlement is effected without the consent of the indemnifying party, such consent not to be unreasonably withheld, conditioned or delayed. 

  
 20 

 (f) Non-exclusive Remedy; Survival. The
indemnification and contribution provided for under this Agreement shall be in addition to any other rights to indemnification or contribution that any indemnified party may have pursuant to law or contract and shall remain in full force and effect
regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and shall survive the transfer of Registrable Securities and the termination or expiration of this
Agreement. 
 Section 8. Underwritten Registrations. 

(a) Participation. No Person may participate in any Public Offering hereunder which is underwritten unless such Person (i) agrees
to sell such Person’s securities in accordance with the applicable prospectus included in a registration statement and on the basis provided in any underwriting arrangements approved by the Person or Persons entitled hereunder to approve such
arrangements (including, without limitation, pursuant to any over-allotment or “green shoe” option requested by the underwriters; provided that no Holder shall be required to sell more than the number of Registrable Securities such
Holder has requested to include) and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements; provided that
no Holder included in any underwritten registration shall be required to make any representations or warranties to the Company or the underwriters (other than representations and warranties regarding such Holder and such Holder’s intended
method of distribution) or to undertake any indemnification obligations to the Company or the underwriters with respect thereto that are materially more burdensome than those provided in Section 7 or those provided by the
other Holders participating in such underwritten registration. Each Holder shall execute and deliver such other agreements as may be reasonably requested by the Company and the managing underwriter(s) that are consistent with such Holder’s
obligations under Section 4, Section 5 and this Section 8(a) or that are necessary to give further effect thereto. To the extent that any such agreement is entered into
pursuant to, and consistent with, Section 4 and this Section 8(a), the respective rights and obligations created under such agreement shall supersede the respective rights and obligations of the
Holders, the Company and the underwriters created pursuant to this Section 8(a). 
 (b) Price and Underwriting
Discounts. In the case of an underwritten Demand Registration or Underwritten Takedown requested by Holders pursuant to this Agreement, the price, underwriting discount and other financial terms of the related underwriting agreement for the
Registrable Securities shall be determined by the Holders representing a majority of the Registrable Securities included in such underwritten offering. 

(c) Suspended Distributions. Each Person that is participating in any registration under this Agreement, upon receipt of any notice from
the Company of the happening of any event of the kind described in Section 5(a)(vi)(B) or (C), shall immediately discontinue the disposition of its Registrable Securities pursuant to the registration statement until
such Person’s receipt of the copies of a supplemented or amended prospectus as contemplated by Section 5(a)(vi). 

  
 21 

 Section 9. Additional Parties; Joinder. The Company may make any Person who acquires Common
Stock or rights to acquire Common Stock from the Company after the date hereof a party to this Agreement (each such Person, an “Additional Holder”) and to succeed to all of the rights and obligations of a Holder under this
Agreement by obtaining an executed joinder to this Agreement from such Additional Holder in the form of Exhibit A attached hereto (a “Joinder”). Upon the execution and delivery of a Joinder by such Additional Holder,
the Common Stock of the Company acquired by such Additional Holder or to which such Additional Holder has the right to acquire (the “Acquired Common”) shall be Registrable Securities to the extent provided herein, such
Additional Holder shall be a Holder under this Agreement with respect to the Acquired Common, and the Company shall add such Additional Holder’s name and address to the Schedule of Holders and circulate such information to the parties to this
Agreement. 
 Section 10. Current Public Information. At all times after the Company has filed a registration statement with the Securities and
Exchange Commission pursuant to the requirements of either the Securities Act or the Exchange Act, the Company shall file all reports required to be filed by it under the Securities Act and the Exchange Act and shall take such further action as any
Holder may reasonably request, all to the extent required to enable such Holders to sell Registrable Securities pursuant to Rule 144. Upon request, the Company shall deliver to any Holder a written statement as to whether it has complied with such
requirements. 
 Section 11. Subsidiary Public Offering. If, after an initial Public Offering of the Capital Stock of one of its Subsidiaries
(including the Company), the Company distributes securities of such Subsidiary to its equityholders, then the rights and obligations of the Company pursuant to this Agreement shall apply, mutatis mutandis, to such Subsidiary, and the Company
shall cause such Subsidiary to comply with such Subsidiary’s obligations under this Agreement. 
 Section 12. MNPI Provisions. 

(a) Each Holder acknowledges that (i) the provisions of this Agreement that require communications by the Company or other Holders to such
Holder may result in such Holder and its Representatives (as defined below) acquiring MNPI (which may include, solely by way of illustration, the fact that an offering of the Company’s securities is pending or the number of Company securities
or the identity of the selling Holders), and (ii) there is no limitation on the duration of time that such Holder and its Representatives may be in possession of MNPI and no requirement that the Company or other Holders make any public
disclosure to cause such information to cease to be MNPI; provided that the Company will use reasonable best efforts to promptly notify each Holder if any proposed registration or offering for which a notice has been delivered pursuant to
this Agreement has been terminated or aborted. 
 (b) Each Holder agrees that it will maintain the confidentiality of such MNPI and, to the
extent such Holder is not a natural person, such confidential treatment shall be in accordance with procedures adopted by it in good faith to protect confidential information of third parties delivered to such Holder
(“Policies”); provided that a Holder may deliver or disclose MNPI to (i) its directors, officers, employees, agents, attorneys, affiliates and financial and other advisors (collectively, the
“Representatives”), but solely to the extent such disclosure reasonably relates to its evaluation of exercise of its rights under this Agreement and the sale of any Registrable Securities in connection with the subject of the
notice, (ii) any federal or state regulatory authority 

  
 22 

 
having jurisdiction over such Holder, (iii) any Person if necessary to effect compliance with any law, rule, regulation or order applicable to such Holder, (iv) in response to any
subpoena or other legal process, or (v) in connection with any litigation to which such Holder is a party; provided, further, that in the case of clause (i), the recipients of such MNPI are subject to the Policies or agree
to hold confidential the MNPI in a manner substantially consistent with the terms of this Section 12 and that in the case of clauses (ii) through (v), such disclosure is required by law and such Holder promptly
notifies the Company of such disclosure to the extent such Holder is legally permitted to give such notice. 
 (c) Each Holder, by its
execution of a counterpart to this Agreement or of a Joinder, hereby acknowledges that it is aware that the U.S. securities laws prohibit any Person who has MNPI about a company from purchasing or selling, directly or indirectly, securities of such
company (including entering into hedge transactions involving such securities), or from communicating such information to any other Person under circumstances in which it is reasonably foreseeable that such Person is likely to purchase or sell such
securities. 
 (d) Each Holder shall have the right, at any time and from time to time (including after receiving information regarding any
potential Public Offering), to elect not to receive any notice that the Company or any other Holders otherwise are required to deliver pursuant to this Agreement by delivering to the Company a written statement signed by such Holder that it does not
want to receive any notices hereunder (an “Opt-Out Request”); in which case and notwithstanding anything to the contrary in this Agreement the Company and other Holders shall not be
required to, and shall not, deliver any notice or other information required to be provided to Holders hereunder to the extent that the Company or such other Holders reasonably expect would result in a Holder acquiring MNPI. An Opt-Out Request may state a date on which it expires or, if no such date is specified, shall remain in effect indefinitely. A Holder who previously has given the Company an
Opt-Out Request may revoke such request at any time, and there shall be no limit on the ability of a Holder to issue and revoke subsequent Opt-Out Requests;
provided that each Holder shall use commercially reasonable efforts to minimize the administrative burden on the Company arising in connection with any such Opt-Out Requests. 

Section 13. Termination of Prior Agreement. The Company and the Holders party to the Prior Agreement hereby agree that the Prior Agreement shall
be terminated and of no further force and effect as of the effectiveness of this Agreement. This Agreement replaces and supersedes the terms of the Prior Agreement. 

Section 14. General Provisions. 
 (a)
Amendments and Waivers. Except as otherwise provided herein, the provisions of this Agreement may be amended, modified or waived only with the prior written consent of the Company and Holders representing a majority of the Registrable
Securities; provided that no such amendment, modification or waiver that would adversely affect a Holder in a manner that is different from any other Holder (provided that the accession by any Additional Holder to this Agreement
pursuant to Section 9 shall not be deemed to adversely affect any Holder), shall be effective against such Holder without the prior written consent of such Holder. The failure or delay of any Person to enforce any of the
provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such Person thereafter to enforce 

  
 23 

 
each and every provision of this Agreement in accordance with its terms. A waiver or consent to or of any breach or default by any Person in the performance by that Person of his, her or its
obligations under this Agreement shall not be deemed to be a consent or waiver to or of any other breach or default in the performance by that Person of the same or any other obligations of that Person under this Agreement. 

(b) Remedies. The parties to this Agreement and their successors and assigns shall be entitled to enforce their rights under this
Agreement specifically (without posting a bond or other security), to recover damages caused by reason of any breach of any provision of this Agreement and to exercise all other rights existing in their favor. The parties hereto and their successors
and assigns agree and acknowledge that a breach of this Agreement would cause irreparable harm and money damages would not be an adequate remedy for any such breach and that, in addition to any other rights and remedies existing hereunder, any party
shall be entitled to specific performance and/or other injunctive relief from any court of law or equity of competent jurisdiction (without posting any bond or other security) in order to enforce or prevent violation of the provisions of this
Agreement. 
 (c) Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be
effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited, invalid, illegal or unenforceable in any respect under any applicable law or regulation in any jurisdiction, such prohibition, invalidity,
illegality or unenforceability shall not affect the validity, legality or enforceability of any other provision of this Agreement in such jurisdiction or in any other jurisdiction, but this Agreement shall be reformed, construed and enforced in such
jurisdiction as if such prohibited, invalid, illegal or unenforceable provision had never been contained herein. 
 (d) Entire
Agreement. Except as otherwise provided herein, this Agreement contains the complete agreement and understanding among the parties hereto with respect to the subject matter hereof and supersedes and preempts any prior understandings, agreements
or representations by or among the parties hereto, written or oral, which may have related to the subject matter hereof in any way. 
 (e)
Successors and Assigns. The rights to cause the Company to register Registrable Securities under this Agreement may be transferred or assigned by each Holder to one or more transferees or assignees of Registrable Securities; provided, that
any such transferee or assignee is an Affiliate of, and after such transfer or assignment continues to be an Affiliate of, such Holder and that each such transferee or assignee assumes in writing responsibility for its portion of the obligations of
such transferring Holder under this Agreement. This Agreement shall bind and inure to the benefit and be enforceable by the Company and its successors and assigns and the Holders and their respective successors and assigns (whether so expressed or
not). In addition, whether or not any express assignment has been made, the provisions of this Agreement which are for the benefit Holders are also for the benefit of, and enforceable by, any subsequent or successor Holder. 

  
 24 

 (f) Notices. Any notice, demand or other communication to be given under or by reason
of the provisions of this Agreement shall be in writing and shall be deemed to have been given or delivered (i) when delivered personally to the recipient, (ii) when sent by confirmed electronic mail if sent during normal business hours of

Section 2. Lock-Up. 

(a) Each Holder hereby agrees that it will not Transfer any Shares or interest therein beneficially owned or owned of record by such Holder

(i) twelve (12) months after the consummation of the Merger; (ii) the date following the consummation of the Merger on which the Company consummates a liquidation, merger, stock exchange or other similar transaction that results in all of
the Company’s stockholders having the right to exchange such stockholders’ Shares for (or having their Shares converted into) cash, securities or other property (or the right to receive any of the foregoing), other than any holding company
reorganization or a transaction that is intended solely to effect a redomestication; and (iii) the date upon which the reported closing price of the Shares equals or exceeds $15.00 per share (as adjusted for stock splits, stock dividends,
reorganizations, recapitalizations and the like) for any twenty (20) trading days within any thirty (30)-trading day period commencing at least one hundred fifty (150) days following the Merger closing (the “Price
Condition”). Notwithstanding the foregoing, no holder may Transfer any Lock-Up Shares for which the Lock-Up Term has terminated as a result of the
satisfaction of the Price Condition until the Shelf Registration Statement (as defined in the Registration Rights Agreement) is declared effective by the U.S. Securities and Exchange Commission. 

(b) Notwithstanding the foregoing restrictions on Transfer set forth in Section 2(a), each Holder may: 

(i) Transfer its Lock-Up Shares (A) to any of its officers or directors, any Affiliate or family
member of any of its officers or directors, as applicable, (B) in the case of an individual, as a gift to such Person’s immediate family or to a trust, the beneficiary of which is a member of such Person’s immediate family, an
Affiliate of such Person or to a charitable organization; (C) in the case of an individual, by virtue of laws of descent and distribution upon death of such Person; or (D) in the case of an individual, pursuant to a qualified domestic
relations order); 

  
 3 

 (ii) Transfer its Lock-Up Shares to any Permitted
Transferee; 
 (iii) Transfer any shares of Common Stock or other securities convertible into or exercisable or exchangeable for Common Stock
acquired in open market transactions after the effective time of the Merger; provided, however, that no such transaction is required to be, or is, publicly announced (whether on Form 4, Form 5 or otherwise, other than a required filing
on Schedule 13F, 13 D, 13D/A, 13G or 13G/A) during the Lock-Up Term; 
 (iv) exercise any options or
warrants to purchase shares of Common Stock (which exercises may be effected on a cashless basis to the extent the instruments representing such options or warrants permit exercises on a cashless basis); provided, however, that such
Holder shall otherwise comply with any restrictions on Transfer applicable to such underlying shares of Common Stock; 
 (v) Transfer any
shares of Common Stock issuable upon exercise of any options that expire during the Lock-Up Term to the Company to satisfy tax withholding obligations as permitted by the compensation committee of the board of
directors of the Company in its discretion pursuant to the Company’s equity incentive plans or arrangements; 
 (vi) Transfer its Lock-Up Shares or other securities convertible into or exercisable or exchangeable for Common Stock to the Company pursuant to any contractual arrangement in effect at the effective time of the Merger that provides
for the repurchase by the Company of the Holder’s Lock-Up Shares or other securities in connection with the termination of such Holder’s service to the Company; 

(vii) Transfer its Lock-Up Shares in transactions approved by the board of directors of the Company in
its discretion to satisfy any U.S. federal, state, or local income tax obligations of such Holder (or its direct or indirect owners) arising from a change in the Code, or the Regulations after the date on which the Merger Agreement was executed by
the parties, and such change prevents the Merger from qualifying as a “reorganization” pursuant to Section 368 of the Code (and the Merger does not qualify for similar tax-free treatment
pursuant to any successor or other provision of the Code or Regulations taking into account such changes); and 
 (viii) Transfer any shares
of Common Stock or other securities acquired as part of the PIPE Investment (as defined in the Merger Agreement) or issued in exchange for, or on conversion or exercise of, any securities issued as part of the PIPE Investment; 

provided, however, that in the case of any Transfer or distribution pursuant to Subsections 2(b)(i) and (ii), (x) in each case
such transferees must enter into a written agreement agreeing to be bound by this Agreement, including the restrictions on Transfer set forth in Section 2(a) and (y) in the case of the foregoing clause (ii), such
Permitted Transferee agrees to promptly Transfer such Lock-Up Shares back to such Holder if such Permitted Transferee ceases to be a Permitted Transferee for any reason prior to the date such Lock-Up Shares becomes freely transferable. Furthermore, Section 2(a) shall not apply to the entry, by such Holder, at any time after the effective time of the Merger, of any trading plan
providing for the sale of shares of Common Stock by such Holder, 

  
 4 

 
which trading plan meets the requirements of Rule 10b5-1(c) under the Securities Exchange Act of 1934, as it may be amended from time to time;
provided, however, that such plan does not provide for, or permit, the sale of any Common Stock during the Lock-Up Term and no public announcement or filing is voluntarily made or required
regarding such plan during the Lock-Up Term. 
 (c) Each of the Holders acknowledges and agrees that
any purported Transfer of Lock-Up Shares in violation of this Agreement shall be null and void ab initio, and the Company shall not be required to register any such purported Transfer. 

Section 3. General Provisions. 
 (a)
Amendments and Waivers. The provisions of this Agreement may be amended, modified or waived only with the prior written consent of the Company and Holders representing a majority of the Lock-Up Shares;
provided that (i) no such amendment, modification or waiver that would adversely affect a Holder in a manner that is different from any other Holder shall be effective against such Holder without the prior written consent of such Holder
and (ii) if any amendment, modification, waiver or release of this Agreement provides any Holder with rights superior to the rights provided to other Holders, such amendment, modification or waiver shall provide such rights to all Holders of Lock-Up Shares, except in the case of (A) waivers granted to a Holder, in the Company’s discretion, necessary to allow a requesting Holder to sell Lock-Up Shares
having a market value, based on the average closing price of the Common Stock on the New York Stock Exchange (or such other market on which the Common Stock is then-listed or quoted) for the three (3) days immediately preceding such proposed
sale, of not more than $500,000, in the aggregate for all such sales by such Holder during the Lock-Up Term, or (B) a waiver or release of any Holder is for the purpose of enabling such Holder to
participate in an Underwritten Takedown (as defined in the Registration Rights Agreement) in which all Holders with similar rights are similarly granted waivers and permitted to participate, provided, that, such waiver or release granted to
each Holder will be solely for the purpose of enabling such Holder to participate in such Underwritten Takedown. The failure or delay of any Person to enforce any of the provisions of this Agreement shall in no way be construed as a waiver of such
provisions and shall not affect the right of such Person thereafter to enforce each and every provision of this Agreement in accordance with its terms. A waiver or consent to or of any breach or default by any Person in the performance by that
Person of his, her or its obligations under this Agreement shall not be deemed to be a consent or waiver to or of any other breach or default in the performance by that Person of the same or any other obligations of that Person under this Agreement.

 (b) Remedies. The parties to this Agreement and their successors and assigns shall be entitled to enforce their rights under this
Agreement specifically (without posting a bond or other security), to recover damages caused by reason of any breach of any provision of this Agreement and to exercise all other rights existing in their favor. The parties hereto and their successors
and assigns agree and acknowledge that a breach of this Agreement would cause irreparable harm and money damages would not be an adequate remedy for any such breach and that, in addition to any other rights and remedies existing hereunder, any party
shall be entitled to specific performance and/or other injunctive relief from any court of law or equity of competent jurisdiction (without posting any bond or other security) in order to enforce or prevent violation of the provisions of this
Agreement. 

  
 5 

 (c) Severability. Whenever possible, each provision of this Agreement shall be
interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited, invalid, illegal or unenforceable in any respect under any applicable law or regulation in any
jurisdiction, such prohibition, invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of any other provision of this Agreement in such jurisdiction or in any other jurisdiction, but this Agreement shall
be reformed, construed and enforced in such jurisdiction as if such prohibited, invalid, illegal or unenforceable provision had never been contained herein. 

(d) Entire Agreement. Except as otherwise provided herein, this Agreement contains the complete agreement and understanding among the
parties hereto with respect to the subject matter hereof and supersedes and preempts any prior understandings, agreements or representations by or among the parties hereto, written or oral, which may have related to the subject matter hereof in any
way. 
 (e) Successors and Assigns. This Agreement shall bind and inure to the benefit and be enforceable by the Company and its
successors and assigns and the Holders and their respective successors and assigns (whether so expressed or not). In addition, whether or not any express assignment has been made, the provisions of this Agreement which are for the benefit Holders
are also for the benefit of, and enforceable by, any subsequent or successor Holder. 
 (f) Notices. Any notice, demand or other
communication to be given under or by reason of the provisions of this Agreement shall be in writing and shall be deemed to have been given or delivered (i) when delivered personally to the recipient, (ii) when sent by confirmed electronic
mail if sent during normal business hours of the recipient but, if not, then on the next Business Day, (iii) one Business Day after it is sent to the recipient by reputable overnight courier service (charges prepaid) or (iv) three Business
