meeting or otherwise cause the Insider Shares to be counted as present thereat for the purpose of establishing a quorum; 
 b. vote (or

the proposals and any other matters necessary or reasonably requested by Parent for consummation of the Merger and the other transactions contemplated by the Plan of Merger; and

this Agreement. 
 2. Transfer of Shares. Except as otherwise contemplated by the Plan of Merger or this Agreement, each Insider
agrees that it shall not, directly or indirectly, (a) sell, assign, transfer (including by operation of law), create any lien or pledge, dispose of or otherwise encumber any of such Insider’s Insider Shares or otherwise agree to do any of
the foregoing, (b) deposit any of such Insider’s Insider Shares into a voting trust or enter into a voting agreement or arrangement or grant any proxy or power of attorney with respect thereto that is inconsistent with this Agreement or

 3. No
Solicitation of Transactions. Each Insider agrees not to directly or indirectly, through any officer, director, representative, agent or otherwise, (a) solicit, initiate or knowingly encourage (including by furnishing information) the

4. Representations and Warranties of the Insiders. Each Insider, severally and not jointly, hereby represents and warrants to Parent

which such Insider is subject or (iii) any change in the rights or obligations of any party under any contract legally binding upon such Insider, except, in the case of clause (ii) or (iii) directly above, for any such breach,

 Exhibit 10.3 

FORM OF SUBSCRIPTION AGREEMENT 

This SUBSCRIPTION AGREEMENT (this “Subscription Agreement”) is entered into on February 18, 2021, by and between
Kaleyra, Inc., a Delaware corporation (the “Company”), and [●] (“Subscriber”). 
 WHEREAS, the
Company has previously entered into that certain Agreement and Plan of Merger, dated as of February 18, 2021 (the “Merger Agreement”), among the Company, Volcano Merger Sub, Inc., a Delaware corporation and direct, wholly-owned
subsidiary of the Company (“Merger Sub”), Vivial Inc., a Delaware Corporation (“Vivial”) and GSO Special Situations Master Fund LP, an exempted limited partnership formed under the laws of the Cayman Islands, solely
in its capacity as the stockholder representative, providing for the combination of Merger Sub with and into Vivial, and the transactions contemplated by the Merger Agreement, the (“Transaction”); 

WHEREAS, concurrently with the execution of this Subscription Agreement, the Company is entering into Subscription Agreements with certain
investors (the “Notes Subscription Agreements”), pursuant to which such investors, upon the terms and subject to the conditions set forth in the Notes Subscription Agreements, shall purchase from the Company, and the Company shall
issue to such investors, up to $200,000,000 of unsecured promissory notes (“Notes”) convertible into shares of the Company’s common stock, par value $0.0001 per share (“Common Stock”), at an initial conversion
price of $16.875 in accordance with the terms thereof and an Indenture to be entered into on the Closing Date (as defined below) between the Company and Wilmington Trust, National Association, as trustee thereunder (such transactions the general
terms of which are as set forth in Exhibit A attached hereto, collectively, the “Notes Financing”), to be consummated concurrently with the Transaction; 

WHEREAS, in connection with the Transaction, Subscriber desires to subscribe for and purchase from the Company, immediately prior to, and
contingent on, the consummation of the Transaction, that number of shares of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), set forth on the signature page hereto (the “Subscribed
Shares”) for a purchase price of $12.50 per share (the “Per Share Price” and the aggregate of such Per Share Price for all Subscribed Shares being referred to herein as the “Purchase Price”), and the
Company desires to issue and sell to Subscriber the Subscribed Shares in consideration of the payment of the Purchase Price by or on behalf of Subscriber to the Company; and 

WHEREAS, on or prior to the Closing Date, the Company will enter into other subscription agreements (each, an “Other Subscription
Agreement”) with certain other institutional accredited investors (the “Other Subscribers”) (each of the Subscriber and each of the Other Subscribers, a “Subscriber”), which are on the same terms and
conditions as the terms and conditions of this Subscription Agreement, pursuant to which such Other Subscribers shall agree to purchase shares of Common Stock on the Closing Date. 

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions,
herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows: 
 1. Subscription.
Subject to the terms and conditions hereof, at the Closing (as defined below), Subscriber hereby agrees to subscribe for and purchase, and the Company hereby agrees to issue and sell to Subscriber, upon the payment of the Purchase Price, the
Subscribed Shares (such subscription and issuance, the “Subscription”). The Company hereby expressly covenants and agrees that the Purchase Price shall be used exclusively to fund the Company’s obligations in connection with
the Transaction. 
 2. Closing. 

a. Subject to the terms of this Subscription Agreement, the consummation of the Subscription contemplated hereby (the
“Closing”) shall occur on the closing date of the Transaction (the “Closing Date”) immediately prior to or concurrently with the consummation of the Transaction. 

 b. At least five (5) Business Days before the anticipated Closing Date,
the Company shall deliver written notice to Subscriber (the “Closing Notice”) specifying (i) the anticipated Closing Date and (ii) the wire instructions for delivery of the Purchase Price to the Company. No later than two
(2) Business Days after receiving the Closing Notice, Subscriber shall deliver to the Company such information as is reasonably requested in the Closing Notice in order for the Company to issue the Subscribed Shares to Subscriber. Subscriber
shall deliver to the Company, on or prior to 8:00 a.m. (Eastern time) (or as soon as practicable after the Company or its transfer agent delivers evidence of the issuance to Subscriber of the Subscribed Shares on and as of the Closing Date) on the
Closing Date the Purchase Price in cash via wire transfer to the account specified in the Closing Notice against (and concurrently with) delivery by the Company to Subscriber of (i) the Subscribed Shares in book entry form, free and clear of
any liens, encumbrances or other restrictions (other than those arising under this Subscription Agreement or state or federal securities laws), in the name of Subscriber (or its nominee in accordance with its delivery instructions) or to a custodian
designated by Subscriber, as applicable, and (ii) written notice from the Company or its transfer agent evidencing the issuance to Subscriber of the Subscribed Shares on and as of the Closing Date. In the event that the consummation of the
Transaction does not occur within seven (7) Business Days after the anticipated Closing Date specified in the Closing Notice, the Company shall promptly (but in no event later than ten (10) Business Days after the anticipated Closing Date
specified in the Closing Notice) return the funds so delivered by Subscriber to the Company by wire transfer in immediately available funds to the account specified by Subscriber. Unless this Subscription Agreement has been terminated pursuant to
Section 6, the failure of the Closing to occur on the anticipated Closing Date set forth in the Closing Notice shall not, on its own, terminate this Subscription Agreement or otherwise relieve any party of any of its
obligations hereunder. For the purposes of this Subscription Agreement, “Business Day” means any day other than Saturday, Sunday or any other day on which commercial banks in The City of New York are authorized or required by law to
remain closed; provided, however, for clarification, commercial banks shall not be deemed to be authorized or required by law to remain closed due to “stay at home”,
“shelter-in-place”, “non-essential employee” or any other similar orders or restrictions or the closure
of any physical branch locations at the direction of any governmental authority so long as the electronic funds transfer systems (including for wire transfers) of commercial banks in The City of New York generally are open for use by customers on
such day. 
 c. The Closing shall be subject to the satisfaction or valid waiver in writing (to the extent a valid waiver is
capable of being issued) by the Company, on the one hand, and the Subscriber, on the other, of the conditions that, on the Closing Date: 

(i) no suspension of the qualification of the Subscribed Shares for sale or trading on the NYSE American, or, to the
Company’s knowledge, initiation or threatening of any proceedings for any of such purposes, shall have occurred and the Subscribed Shares shall be approved and duly listed for trading on the NYSE American; 

(ii) all conditions precedent to the closing of the Transaction set forth in the Merger Agreement, including, without
limitation, the approval of the Company’s stockholders, shall have been satisfied or waived, as determined by the parties to the Merger Agreement, and the closing of the Transaction shall occur concurrently with or immediately following the
Closing; 
 (iii) no governmental authority shall have enacted, issued, promulgated, enforced or entered any judgment, order,
law, rule or regulation (whether temporary, preliminary or permanent) which is then in effect and has the effect of making consummation of the transactions contemplated hereby illegal or otherwise restraining, prohibiting or enjoining consummation
of the transactions contemplated hereby (except in the case of a governmental authority located outside the United States where such judgment, order, law, rule or regulation would not be reasonably expected to have a Company Material Adverse Effect
(as defined below)); and no such governmental authority shall have instituted or threatened in writing a proceeding seeking to impose any such restraint or prohibition (except in the case of a governmental authority located outside the United States
where such restraint or prohibition would not be reasonably expected to have a Company Material Adverse Effect); and 

  
 2 

 (iv) all conditions precedent to the closing of the Notes Financing set
forth in the Notes Subscription Agreements shall have been satisfied or waived, and the Closing shall occur concurrently with the closing of the Notes Financing. 

d. The obligation of the Company to consummate the Closing shall be subject to the satisfaction or valid waiver by the Company
of the additional conditions that, on the Closing Date: 
 (i) all representations and warranties of Subscriber contained in
this Subscription Agreement are true and correct in all material respects (other than representations and warranties that are qualified as to materiality or Subscriber Material Adverse Effect (as defined below), which representations and warranties
shall be true in all respects) at and as of the Closing Date (except for such representations and warranties with respect to a specified date, which shall be true and correct as of such specified date), and consummation of the Closing shall
constitute a reaffirmation by Subscriber of each of the representations and warranties of Subscriber contained in this Subscription Agreement as of the Closing (except for such representations and warranties with respect to a specified date, which
shall be true and correct as of such specified date); and 
 (ii) Subscriber shall have performed, satisfied and complied in
all material respects with all covenants, agreements and conditions required by this Subscription Agreement to be performed, satisfied or complied with by it at or prior to the Closing, except where the failure of such performance or compliance
would not or would not reasonably be expected to prevent, materially delay, or materially impair the ability of the Company to consummate the Closing. 

e. The obligation of Subscriber to consummate the Closing shall be subject to the satisfaction or valid waiver in writing by
Subscriber of the additional conditions that, on the Closing Date: 
 (i) all representations and warranties of the Company
contained in this Subscription Agreement are true and correct in all material respects (other than representations and warranties that are qualified as to materiality or Company Material Adverse Effect (as defined below), which representations and
warranties shall be true in all respects) at and as of the Closing Date, and consummation of the Closing shall constitute a reaffirmation by the Company of each of the representations and warranties of the Company contained in this Subscription
Agreement as of the Closing; 
 (ii) the Company shall have performed, satisfied and complied in all material respects with
all covenants, agreements and conditions required by this Subscription Agreement to be performed, satisfied or complied with by it at or prior to the Closing; 

(iii) there shall have been no amendment, waiver or modification to the Merger Agreement that materially and adversely affects
the Company or the Subscriber’s investment in the Company; 
 (iv) the Company shall not have entered into any Other
Subscription Agreement with a lower Per Share Price or other terms (economic or otherwise) more favorable to an Other Subscriber or investor than as set forth in this Subscription Agreement; and 

(v) there has not occurred any Company Material Adverse Effect (as defined below) or any Material Adverse Effect (as defined in
the Merger Agreement). 
 3. Company Representations and Warranties. For purposes of this Section 3,
the term “Company” shall refer to the Company as of the date hereof and, for purposes of only the representations contained in subsections (f), (i), (k) and (n) of this Section 3 and to the extent such
representations and warranties are made as of the Closing Date, the combined company after giving effect to the Transaction as of the Closing Date. The Company represents and warrants to Subscriber that: 

a. The Company (i) is duly organized, validly existing and in good standing under the laws of the State of Delaware,
(ii) has the requisite power and authority to own, lease and operate its properties, to carry on its business as it is now being conducted and to enter into and perform its obligations under this Subscription Agreement, and (iii) is duly
licensed or qualified to conduct its business and, if applicable, is in 

  
 3 

 
good standing under the laws of each jurisdiction (other than its jurisdiction of incorporation) in which the conduct of its business or the ownership of its properties or assets requires such
license or qualification, except, with respect to the foregoing clause (iii), where the failure to be in good standing would not reasonably be expected to have a Company Material Adverse Effect. For purposes of this Subscription Agreement, a
“Company Material Adverse Effect” means an event, effect or occurrence that, individually or in the aggregate, is or has a material adverse effect on the business or results of operations of the Company, taken as a whole;
provided, that the following shall not be taken into account in determining whether a “Company Material Adverse Effect” shall have occurred: (a) any global, international or national or any foreign or domestic regional
economic, financial, social or political conditions; (b) general economic conditions, including changes in any financial, debt, credit, currency, capital or banking markets or conditions (including any disruption thereof), in each case in the
United States or anywhere else in the world; (c) changes in interest, currency or exchange rates or the price of any commodity, security or market index; (d) changes in legal or regulatory conditions, including changes or proposed changes
in law or binding directives issued by any governmental entity, or any changes or proposed changes in GAAP or other accounting principles or requirements, or, in each case, any change or proposed change in standards, interpretations or enforcement
thereof, or the adoption of any new law or directive, or the rescission, expiration or retirement of any Law or directive; (e) changes in the industries in which the Company operates or ordinary course seasonal fluctuations in the business of
the Company that are of a magnitude consistent with past such seasonal fluctuations; (f) the occurrence, escalation, outbreak or worsening of any hostilities, war, police action, acts of terrorism or military conflicts, whether or not pursuant
to the declaration of an emergency or war; (g) the existence, occurrence or continuation of any force majeure events, including any earthquakes, floods, hurricanes, tropical storms, fires or other natural disasters, any national, international
or regional calamity, epidemic, pandemic or disease outbreak (including the COVID-19 virus); (h) any change in, or failure of the Company to meet, or the publication of any report regarding, any internal or
public projections, forecasts, budgets or estimates of or relating to the Company for any period, including with respect to revenue, earnings, cash flow or cash position; (i) the taking or not taking of any action to the extent required by this
Agreement; (j) compliance by the Company or any of its Subsidiaries with the express requirements of the terms of this Agreement, the Merger Agreement and the other transaction documents (as applicable), including the failure to take any action
restricted by this Agreement, the Merger Agreement or the other transaction documents; provided, however, that any event, occurrence, fact condition or change referred to in clauses (a) through (g) immediately above shall be taken
into account in determining whether a Company Material Adverse Effect has occurred or could reasonably be expected to occur to the extent that such event, occurrence, fact, condition or change has a disproportionate effect on the Company compared to
other participants in the industries in which the Company conducts its businesses, and provided, further, that the underlying causes of such instances set forth in clauses (a) through (j) may, if they are not otherwise excluded from the
definition of Company Material Adverse Effect, be taken into account in determining whether a Company Material Adverse Effect has occurred). 

b. The Subscribed Shares have been duly authorized and, when issued and delivered to Subscriber against full payment therefor
in accordance with the terms of this Subscription Agreement, will be validly issued, fully paid and non-assessable and will not have been issued in violation of any preemptive rights created under the
Company’s organizational documents or the laws of the State of Delaware. 
 c. The Subscribed Shares are not, and
following the Closing, will not be, subject to any Transfer Restriction. The term “Transfer Restriction” means any condition to or restriction on the ability of the Subscriber or any other holder of the Subscribed Shares to pledge, sell,
assign or otherwise transfer the Subscribed Shares under any organizational document, policy or agreement of, by or with the Company, but excluding the restrictions on transfer described in Section 4(e) of this Subscription Agreement with
respect to the status of the Subscribed Shares as “restricted securities” pending their registration for resale under the Securities Act of 1933, as amended (the “Securities Act”) in accordance with the terms of this
Subscription Agreement or their eligibility to be sold pursuant to Rule 144.

 d. This Subscription Agreement has been duly authorized, executed and
delivered by the Company, and assuming the due authorization, execution and delivery of the same by Subscriber, this Subscription Agreement shall constitute the valid and legally binding obligation of the Company, enforceable against the Company in
accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors generally and by the availability of equitable remedies. 

e. The execution and delivery of this Subscription Agreement, the issuance and sale of the Subscribed Shares and the compliance
by the Company with all of the provisions of this Subscription Agreement and the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a
default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of the Company pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or
other agreement or instrument to which the Company is a party or by which the Company is bound or to which any of the property or assets of the Company is subject; (ii) the organizational documents of the Company; or (iii) any statute or
any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over the Company or any of its properties that, in the case of clauses (i) and (iii), would reasonably be expected to
have a Company Material Adverse Effect or have a material adverse effect on the Company’s ability to consummate the transactions contemplated hereby, including the issuance and sale of the Subscribed Shares. 

f. Assuming the accuracy of the representations and warranties of the Subscriber, the Company is not required to obtain any
consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority, self-regulatory organization (including the NYSE American or other

consummate the Transaction as provided under the Merger Agreement, (v) the filing of notification under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, if applicable, and (vi) the failure of which to obtain would not be
reasonably expected to have a Company Material Adverse Effect or have a material adverse effect on the Company’s ability to consummate the transactions contemplated hereby, including the issuance and sale of the Subscribed Shares. 

g. As of their respective dates, all reports required to be filed by the Company with the United States Securities and Exchange
Commission (“Commission”) (the “SEC Reports”) complied in all material respects with the requirements of the Securities Act and the Securities Exchange Act of 1934, as amended (the “Exchange Act”),
and the rules and regulations of the Commission promulgated thereunder, and none of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in
order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The financial statements of the Company included in the SEC Reports comply in all material respects with applicable accounting
requirements and the rules and regulations of the Commission with respect thereto as in effect at the time of filing and fairly present in all material respects the financial position of the Company as of and for the dates thereof and the results of
operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, year-end audit adjustments. A copy of each SEC Report is available to the Subscriber via the
Commission’s EDGAR system. The Company has timely filed each report, statement, schedule, prospectus, and registration statement that the Company was required to file with the Commission since its initial registration of Common Stock with the
Commission.

Company consists of 100,000,000 shares of Common Stock and 1,000,000 shares of preferred stock, par value $0.0001 per share (“Preferred Shares”). As of the Closing Date (and immediately after the consummation of the

filings with the Commission. All (i) issued and outstanding Common Stock has been duly authorized and validly issued, is fully paid and non-assessable and is not subject to preemptive rights and
(ii) issued and outstanding Warrants and Rights constitute legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms. As of the date hereof, except as set forth above and pursuant
to the Other Subscription Agreements, the Note Subscription Agreements and the Merger Agreement, there are no outstanding options, warrants or other rights to subscribe for, purchase or acquire from the Company any Common Stock or other equity
interests in the Company (collectively, “Equity Interests”) or securities convertible into or exchangeable or exercisable for Equity Interests. As of the date hereof, the Company has no subsidiaries and does not own, directly
or indirectly, interests or investments (whether equity or debt) in any person, whether incorporated or unincorporated. There are no stockholder agreements, voting trusts or other agreements or understandings to which the Company is a party or
by which it is bound relating to the voting, transfer or registration of any Equity Interests, other than as contemplated by the Merger Agreement. There are no securities or instruments issued by or to which the Company is a party containing
anti-dilution or similar provisions that will be triggered by the issuance of (i) the Subscribed Shares, (ii) the shares to be issued pursuant to any Other Subscription Agreement, (iii) any Notes to be issued pursuant to the Notes
Subscription Agreements or (iv) any shares of Common Stock issuable upon conversion of any Notes to be issued pursuant to the Notes Subscription Agreements. 

i. Except for such matters as have not had and would not be reasonably expected to have a Company Material Adverse Effect or
have a material adverse effect on the Company’s ability to consummate the transactions contemplated hereby, including the issuance and sale of the Subscribed Shares, as of the date hereof, there is no (i) suit, action, proceeding,
investigation or arbitration before a governmental authority or arbitrator pending, or, to the knowledge of the Company, threatened in writing against the Company or (ii) judgment, decree, injunction, ruling or order of any governmental
authority or arbitrator outstanding against the Company. 
 j. The issued and outstanding shares of Common Stock are
registered pursuant to Section 12(b) of the Exchange Act, and are listed for trading on the NYSE American under the symbol “KLR”. There is no suit, action, proceeding or investigation pending or, to the knowledge of the Company,
threatened against the Company by the NYSE American or the Commission with respect to any intention by such entity to deregister the shares of Common Stock or prohibit or terminate the listing of the shares of Common Stock on the NYSE American. The
Company has taken no action that is designed to terminate the registration of the shares of Common Stock under the Exchange Act. 

k. Assuming the accuracy of Subscriber’s representations and warranties set forth in Section 4
of this Subscription Agreement, no registration under the Securities Act is required for the offer and sale of the Subscribed Shares by the Company to Subscriber and the Subscribed Shares are not being offered in a manner involving a public offering
under, or in a distribution in violation of, the Securities Act or any state securities laws.

any person acting on its behalf has engaged or will engage in any form of general solicitation or general advertising (within the meaning of Regulation D) in connection with any offer or sale of the Subscribed Shares.

 6 

 n. Except for such matters as have not had a Company Material Adverse
Effect, the Company is, and has been since its inception, in compliance with all state and federal laws applicable to the conduct of its business. The Company has not received any written, or to its knowledge, other communication from a governmental
entity that alleges that the Company is not in compliance with or is in default or violation of any applicable law, except where such non-compliance, default or violation would not be reasonably expected to
have, individually or in the aggregate, a Material Adverse Effect. Except for such matters as have not had and would not be reasonably expected to have, individually or in the aggregate, a Material Adverse Effect, there is no (i) action,
lawsuit, claim or other proceeding or investigation, in each case by or before any governmental authority pending, or, to the knowledge of the Company, threatened against the Company or (ii) judgment, decree, injunction, ruling or order of any
governmental entity or arbitrator outstanding against the Company. 
 o. The Company has not entered into any subscription
agreement, side letter or similar agreement with any investor in connection with such investor’s direct or indirect investment in the Company other than (i) the Merger Agreement, (ii) the Note Subscription Agreements, and

thereunder than the terms of this Subscription Agreement. 
 p. The Company has not disclosed to Subscriber information that
would constitute material non-public information as of the Closing Date other than the existence of the transactions contemplated hereby. 

q. Neither the Company nor, to the Company’s knowledge, Vivial has received a Paycheck Protection Program (PPP) loan under

Subscriber represents and warrants to the Company and the Placement Agent that: 
 a. Subscriber (i) is duly
organized, validly existing and in good standing under the laws of its jurisdiction of incorporation, and (ii) has the requisite power and authority to enter into and perform its obligations under this Subscription Agreement. 

b. This Subscription Agreement has been duly executed and delivered by Subscriber, and assuming the due authorization,
execution and delivery of the same by the Company, this Subscription Agreement shall constitute the valid and legally binding obligation of Subscriber, enforceable against Subscriber in accordance with its terms, except as such enforceability may be
limited by bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors generally and by the availability of equitable remedies. 

c. The execution and delivery of this Subscription Agreement, the purchase of the Subscribed Shares and the compliance by
Subscriber with all of the provisions of this Subscription Agreement and the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default
under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of Subscriber pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other
agreement or instrument to which Subscriber is a party or by which Subscriber is bound or to which any of the property or assets of Subscriber is subject; (ii) the organizational documents of Subscriber; or (iii) any statute or any
judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over Subscriber or any of its properties that, in the case of clauses (i) and (iii), would reasonably be expected to have
a Subscriber Material Adverse Effect. For purposes of this Subscription Agreement, a “Subscriber Material Adverse Effect” means an event, change, development, occurrence, condition or effect with respect to Subscriber that would
reasonably be expected to have a material adverse effect on Subscriber’s ability to consummate the transactions contemplated hereby, including the purchase of the Subscribed Shares. 

  
 7 

 d. Subscriber (i) is a “qualified institutional buyer” (as
defined in Rule 144A under the Securities Act) or an institutional “accredited investor” (within the meaning of Rule 501(a)(1), (2), (3), (7), (8), (9) or (12) under the Securities Act) satisfying the applicable requirements set forth
on Annex A hereto and an “institutional account” as defined in FINRA Rule 4512(c), (ii) is acquiring the Subscribed Shares only for its own account and not for the account of others, or if Subscriber is subscribing for the Subscribed
Shares as a fiduciary or agent for one or more investor accounts, each owner of such account is a “qualified institutional buyer” or an institutional “accredited investor” and Subscriber has full investment discretion with
respect to each such account, and the full power and authority to make the acknowledgements, representations and agreements herein on behalf of each owner of each such account, and (iii) is not acquiring the Subscribed Shares with a view to, or
for offer or sale in connection with, any distribution thereof in violation of the Securities Act (and has provided the Company with the requested information on Annex A following the signature page hereto). Subscriber is not an entity formed for
the specific purpose of acquiring the Subscribed Shares. 
 e. Subscriber understands that the Subscribed Shares are being
offered in a transaction not involving any public offering within the meaning of the Securities Act and that the Subscribed Shares have not been registered under the Securities Act. Subscriber understands that the Subscribed Shares may not be
resold, transferred, pledged or otherwise disposed of by Subscriber absent an effective registration statement under the Securities Act, except (i) to the Company or a subsidiary thereof, (ii) following any sale of such Subscribed Shares
pursuant to Rule 144 of the Securities Act (“Rule 144”) (assuming the transferor is not an affiliate of the Company), (iii) pursuant to Rule 144 if such Subscribed Shares are eligible to be sold, assigned or transferred under Rule
144 (provided that, if the Subscribed Shares have not previously been de-legended, the Subscriber provides the Company with reasonable assurances that such Subscribed Shares are eligible for sale, assignment
or transfer under Rule 144 which assurances shall not require an opinion of Subscriber’s counsel), (iv) in connection with a sale, assignment or other transfer (other than under Rule 144), provided that the Subscriber provides the Company with
an opinion of counsel to the Subscriber, in a generally acceptable form, to the effect that such sale, assignment or transfer of the Subscribed Shares may be made without registration under the applicable requirements of the Securities Act or
(v) if the Securities Act legend below is not required under applicable requirements of the Securities Act (including, without limitation, controlling judicial interpretations and pronouncements issued by the Commission), and any book-entry
position or certificates representing the Subscribed Shares shall not contain a legend to such effect. Subscriber understands that it has been advised to consult legal counsel prior to making any offer, resale, pledge or transfer of any of the
Subscribed Shares. 
 Each book entry for the Subscribed Shares shall contain a notation, and each certificate (if any) evidencing the
Subscribed Shares shall be stamped or otherwise imprinted with a legend, in substantially the following form: 
 “THIS SECURITY AND THE
COMMON STOCK, IF ANY, ISSUABLE UPON CONVERSION OF THIS SECURITY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION, AND MAY NOT BE SOLD OR TRANSFERRED IN THE
ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM. NOTWITHSTANDING THE FOREGOING, THIS SECURITY AND THE COMMON STOCK, IF ANY, ISSUABLE UPON CONVERSION OF THIS SECURITY MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN
OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.” 
 Upon request of Subscriber, upon receipt by the Company of reasonable assurances
from Subscriber that the Subscribed Shares are eligible for sale, assignment or transfer under Rule 144 which assurances shall not require an opinion of Subscriber’s counsel, the Company shall promptly cause the legend to be removed from any
book-entry position or certificate evidencing the Subscribed Shares. 
 f. Subscriber understands and agrees that Subscriber
is purchasing the Subscribed Shares directly from the Company. Subscriber further acknowledges that there have not been, and Subscriber hereby agrees that 

  
 8 

 
it is not relying on, any representations, warranties, covenants or agreements made to Subscriber by the Company, any other party to the Transaction or any other person or entity (including the
Placement Agent), expressly or by implication, other than those representations, warranties, covenants and agreements of the Company set forth in this Subscription Agreement, and Subscriber is not relying on any representations, warranties or
covenants other than those expressly set forth herein. Subscriber acknowledges that certain information provided by the Company was based on projections, and such projections were prepared based on assumptions and estimates that are inherently
uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the projections. 

g. In making its decision to purchase the Subscribed Shares, Subscriber has relied solely upon independent investigation made
by Subscriber and upon the representations, warranties and covenants set forth herein. Subscriber acknowledges and agrees that Subscriber has received such information as Subscriber deems necessary in order to make an investment decision with
respect to the Subscribed Shares, including with respect to the Company and the Transaction. Without limiting the generality of the foregoing, Subscriber acknowledges that Subscriber has had an opportunity to review the Company’s filings with
the Commission. Subscriber represents and agrees that Subscriber and Subscriber’s professional advisor(s), if any, have had the opportunity to ask such questions, receive such answers and obtain such information as Subscriber and such
Subscriber’s professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the Subscribed Shares. Subscriber acknowledges and agrees that neither Oppenheimer & Co. Inc., acting as placement agent
to the Company (the “Placement Agent”), nor any affiliate of the Placement Agent has provided Subscriber with any information or advice with respect to the Subscribed Shares nor is such information or advice necessary or desired.
Neither the Placement Agent nor any of its affiliates has made or makes any representation as to the Company, Vivial, Merger Sub or the quality or value of the Subscribed Shares and the Placement Agent and any of its respective affiliates may have
acquired non-public information with respect to the Company, Vivial, or Merger Sub which Subscriber agrees need not be provided to it. In connection with the issuance of the Subscribed Shares to Subscriber,
neither the Placement Agent nor any of its affiliates has acted as a financial advisor or fiduciary to Subscriber. 
 h.
Subscriber became aware of this offering of the Subscribed Shares solely by means of direct contact between Subscriber and the Company or by means of contact from the Placement Agent, Vivial, Merger Sub and/or their respective advisors (including,
without limitation, attorneys, accountants, bankers, consultants and financial advisors), agents, control persons, representatives, affiliates, directors, officers, managers, members, and/or employees, and/or the representatives of such persons
(such parties referred to collectively as “Representatives”). The Subscribed Shares were offered to Subscriber solely by direct contact between Subscriber and the Company, the Placement Agent, Vivial, Merger Sub and/or their
respective Representatives. Subscriber acknowledges that it is not relying upon, and has not relied upon, any statement, representation or warranty made by any person or entity (including, without limitation, the Company, the Placement Agent,
Vivial, Merger Sub and/or their respective Representatives), other than the representations and warranties contained in this Subscription Agreement, in making its investment or decision to invest in the Company. Subscriber did not become aware of
this offering of the Subscribed Shares, nor were the Subscribed Shares offered to Subscriber, by any other means, and none of the Company, the Placement Agent, Vivial, Merger Sub or their respective Representatives acted as investment advisor,
broker or dealer to Subscriber. Subscriber acknowledges that the Company represents and warrants that the Subscribed Shares (i) were not offered by any form of general solicitation or general advertising and (ii) are not being offered in a
manner involving a public offering under, or in a distribution in violation of, the Securities Act, or any state securities laws. 

i. Subscriber acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the
Subscribed Shares. Subscriber has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Subscribed Shares, and Subscriber has had an opportunity to seek, and has
sought, such accounting, legal, business and 

  
 9 

 
tax advice as Subscriber has considered necessary to make an informed investment decision. Subscriber acknowledges that it (i) is a sophisticated investor, experienced in investing in
private equity transactions and capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities and (ii) has exercised independent judgment
in evaluating its participation in the purchase of the Subscribed Shares. 
 j. Alone, or together with any professional
advisor(s), Subscriber represents and acknowledges that Subscriber has adequately analyzed and fully considered the risks of an investment in the Subscribed Shares and determined that the Subscribed Shares are a suitable investment for Subscriber
and that Subscriber is able at this time and in the foreseeable future to bear the economic risk of a total loss of Subscriber’s investment in the Company. Subscriber acknowledges specifically that a possibility of total loss exists. 

k. Subscriber understands and agrees that no federal or state agency has passed upon or endorsed the merits of the offering of
the Subscribed Shares or made any findings or determination as to the fairness of this investment. 
 l. Subscriber is not
(i) a person or entity named on the List of Specially Designated Nationals and Blocked Persons administered by the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) or in any Executive Order issued by
the President of the United States and administered by OFAC, or a person or entity prohibited by any OFAC sanctions program, or a person or entity whose property and interests in property subject to U.S. jurisdiction are otherwise blocked under any
U.S. laws, Executive Orders or regulations, (ii) a person or entity listed on the Sectoral Sanctions Identifications (“SSI”) List maintained by OFAC or otherwise determined by OFAC to be subject to one or more of the Directives
issued under Executive Order 13662 of March 20, 2014, or on any other of the OFAC Consolidated Sanctions Lists, (iii) an entity owned, directly or indirectly, individually or in the aggregate, 50 percent or more by one or more persons
described in subsections (i) or (ii), (iv) a person or entity named on the U.S. Department of Commerce, Bureau of Industry and Security (“BIS”) Denied Persons List, Entity List, or Unverified List (“BIS
Lists”) (collectively with (i) through (iv), a “Restricted Person”) or (v) a non-U.S. shell bank or providing banking services indirectly to a
non-U.S. shell bank. Subscriber agrees to provide law enforcement agencies, if requested thereby, such records as required by applicable law, provided that Subscriber is permitted to do so under applicable
law. Subscriber represents that if it is a financial institution subject to the Bank Secrecy Act (31 U.S.C. Section 5311 et seq.), as amended by the USA PATRIOT Act of 2001 and its implementing regulations (collectively, the
“BSA/PATRIOT Act”), that Subscriber maintains policies and procedures reasonably designed to comply with applicable obligations under the BSA/PATRIOT Act. Subscriber also represents that, to the extent required, it maintains
policies and procedures reasonably designed for the screening of its investors against the OFAC and BIS sanctions programs, including for Restricted Persons, and otherwise to ensure compliance with all applicable sanctions and embargo laws,
statutes, and regulations. Subscriber further represents and warrants that, to the extent required, it maintains policies and procedures reasonably designed to ensure that the funds held by Subscriber and used to purchase the Subscribed Shares were
legally derived. 
 m. Subscriber does not have, as of the date hereof, and during the
30-day period immediately prior to the date hereof Subscriber has not entered into, any “put equivalent position” as such term is defined in Rule 16a-1 under
the Exchange Act or short sale positions with respect to the securities of the Company. Notwithstanding the foregoing, (i) nothing herein shall prohibit other entities under common management with Subscriber that have no knowledge of this
Subscription Agreement or of Subscriber’s participation in the transactions contemplated by this Subscription Agreement (including Subscriber’s controlled affiliates and/or affiliates) from entering into any “short sales” and
(ii) in the case of a Subscriber that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of Subscriber’s assets and the portfolio managers have no direct knowledge of the investment decisions
made by the portfolio managers managing other portions of Subscriber’s assets, the representation set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to
purchase the Subscribed Shares covered by this Subscription Agreement. It is expressly understood and agreed that for all purposes of this Subscription Agreement, and without implication that the 

  
 10 

 
contrary would otherwise be true, neither transactions nor purchases nor sales shall include the location and/or reservation of borrowable shares of Common Stock. 

n. If Subscriber is an employee benefit plan that is subject to Title I of ERISA, a plan, an individual retirement account or
other arrangement that is subject to Section 4975 of the Code or an employee benefit plan that is a governmental plan (as defined in Section 3(32) of ERISA), a church plan (as defined in Section 3(33) of ERISA), a non-U.S. plan (as described in Section 4(b)(4) of ERISA) or other plan that is not subject to the foregoing but may be subject to provisions under any other federal, state, local,
non-U.S. or other laws or regulations that are similar to such provisions of ERISA or the Internal Revenue Code of 1986, as amended, or an entity whose underlying assets are considered to include “plan
assets” of any such plan, account or arrangement (each, a “Plan”) subject to the fiduciary or prohibited transaction provisions of ERISA or Section 4975 of the Code, the Subscriber represents and warrants that neither the
Company, nor any of its respective affiliates (the “Transaction Parties”) has acted as the Plan’s fiduciary, or has been relied on for advice, with respect to its decision to acquire and hold the Subscribed Shares, and none of
the Transaction Parties shall at any time be relied upon as the Plan’s fiduciary with respect to any decision to acquire, continue to hold or transfer the Subscribed Shares. 

o. Subscriber at the Closing will have sufficient funds to pay the Purchase Price pursuant to
Section 2(b) of this Subscription Agreement. 
 p. Subscriber has not received any disclosure or
offering document from the Placement Agent in connection with the offer and sale of the Subscribed Shares. In connection with the issue and purchase of the Subscribed Shares, the Placement Agent has not acted as the Subscriber’s financial
advisor or fiduciary. 
 q. Subscriber agrees that, notwithstanding Section 7(i) of this
Subscription Agreement, the Placement Agent, Vivial and Merger Sub may rely upon the representations and warranties made by Subscriber to the Company in this Subscription Agreement. 

r. No foreign person (as defined in 31 C.F.R. Part 800.224) in which the national or subnational governments of a single
foreign state have a substantial interest (as defined in 31 C.F.R. Part 800.244) will acquire a substantial interest in the Company as a result of the purchase by and sale of the Subscribed Shares hereunder such that a declaration to the Committee
on Foreign Investment in the United States would be mandatory under 31 C.F.R. Part 800.401, and no foreign person will have control (as defined in 31 C.F.R. Part 800.208) over the Company from and after the Closing as a result of the purchase and
sale of the Subscribed Shares hereunder. 
 s. Except as expressly disclosed in a Schedule 13D or Schedule 13G (or amendments
thereto) filed by Subscriber with the Commission with respect to the beneficial ownership of the Company’s Common Stock prior to the date hereof, Subscriber is not currently (and at all times through Closing will refrain from being or becoming)
a member of a “group” (within the meaning of Section 13(d)(3) or Section 14(d)(2) of the Exchange Act or any successor provision) acting for the purpose of acquiring, holding or disposing of equity securities of the Company
(within the meaning of Rule 13d-5(b)(1) under the Exchange Act). 
 t. Except for the
representations and warranties contained in this Section 4, Subscriber makes no express or implied representation or warranty, and Subscriber hereby disclaims any such representation or warranty with respect to the execution and delivery of
this Subscription Agreement and the consummation of the transactions contemplated herein. 
 5. Registration of Subscribed Shares.

 a. The Company agrees that, prior to the Closing Date (the “Filing Deadline”), the Company will file with
the Commission (at the Company’s sole cost and expense) a registration statement (the “Registration Statement”) registering the resale of all of the Subscribed Shares, and the Company shall use its commercially reasonable
efforts to have the Registration Statement declared effective upon the Closing, but no later than the 60th calendar day (or 90th calendar day
if the Commission notifies the Company that it will “review” the Registration Statement) following the Filing Deadline (such date, the “Effectiveness Date”); 

  
 11 

 
provided, however, that the Company’s obligations to include the Subscribed Shares in the Registration Statement are contingent upon Subscriber furnishing in writing to the Company such
information regarding Subscriber, the securities of the Company held by Subscriber and the intended method of disposition of the Subscribed Shares as shall be reasonably requested by the Company to effect the registration of the Subscribed Shares,
and shall execute such documents in connection with such registration as the Company may reasonably request that are customary of a selling stockholder in similar situations. For the avoidance of doubt, the Subscriber shall not in connection with
the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer the Subscribed Shares. The Company will use its
commercially reasonable efforts to maintain the continuous effectiveness of the Registration Statement, and to be supplemented and amended to the extent necessary to ensure that such Registration Statement is available or, if not available, that
another registration statement is available for the resale of the Subscribed Shares, until the earliest of (i) the date on which the Subscribed Shares may be resold without volume or manner of sale limitations pursuant to Rule 144
promulgated under the Securities Act, (ii) the date on which such Subscribed Shares have actually been sold and (iii) the date which is two years after the Closing. For purposes of clarification, any failure by the Company to file the
Registration Statement by the Filing Deadline or to effect such Registration Statement by the Effectiveness Date shall not otherwise relieve the Company of its obligations to file or effect the Registration Statement set forth in this
Section 5. 
 b. Notwithstanding anything to the contrary in this Subscription Agreement, the
Company shall be entitled to delay or postpone the effectiveness of the Registration Statement, and from time to time to require any Subscriber not to sell under the Registration Statement or to suspend the effectiveness thereof, if the negotiation
or consummation of a transaction by the Company or its subsidiaries is pending or an event has occurred, which negotiation, consummation or event, the Company’s board of directors reasonably believes, upon the advice of external legal counsel,
would require additional disclosure by the Company in the Registration Statement of material information that the Company has a bona fide business purpose for keeping confidential and the non-disclosure of
which in the Registration Statement would be expected, in the reasonable determination of the Company’s board of directors, upon the advice of external legal counsel, to cause the Registration Statement to fail to comply with applicable
disclosure requirements (each such circumstance, a “Suspension Event”); provided, however, that the Company may not delay or suspend the Registration Statement on more than two occasions or for more than sixty (60) consecutive
calendar days, or more than ninety (90) total calendar days, in each case during any twelve-month period. Upon receipt of any written notice from the Company of the happening of any Suspension Event (which notice shall not contain material non-public information) during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a
material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the prospectus) not misleading, Subscriber agrees
that (i) it will immediately discontinue offers and sales of the Subscribed Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until Subscriber receives copies of a supplemental
or amended prospectus (which the Company agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by the
Company that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by the Company unless otherwise required by law or subpoena. If so directed by the
Company, Subscriber will deliver to the Company or, in Subscriber’s sole discretion destroy, all copies of the prospectus covering the Subscribed Shares in Subscriber’s possession; provided, however, that this obligation to deliver or
destroy all copies of the prospectus covering the Subscribed Shares shall not apply (i) to the extent Subscriber is required to retain a copy of such prospectus (a) in order to comply with applicable legal, regulatory, self-regulatory or
professional requirements or (b) in accordance with a bona fide pre-existing document retention policy or (ii) to copies stored electronically on archival servers as a result of automatic data back-up. Notwithstanding anything to the contrary, the Company shall cause its transfer agent to deliver unlegended shares of Common Stock to a transferee of the 

  
 12 

 
Subscriber in connection with any sale of Subscribed Shares with respect to which the Subscriber has entered into a contract for sale, prior to the Subscriber’s receipt of the notice of a
Suspension Event and for which the Subscriber has not yet settled. 
 c. The Company shall, notwithstanding any termination
of this Subscription Agreement, indemnify, defend and hold harmless Subscriber (to the extent a seller under the Registration Statement), and its officers, directors and agents, and each person who controls Subscriber (within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act) to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable
external attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon (i) any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any
prospectus included in the Registration Statement or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to state a material fact
required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, or (ii) any
violation or alleged violation by the Company of the Securities Act, Exchange Act or any state securities law or any rule or regulation thereunder, in connection with the performance of its obligations under this Section 5,
except to the extent, but only to the extent, that such untrue statements, alleged untrue statements, omissions or alleged omissions are based upon information regarding Subscriber furnished in writing to the Company by Subscriber expressly for use
therein or Subscriber has omitted a material fact from such information or otherwise violated the Securities Act, Exchange Act or any state securities law or any rule or regulation thereunder; provided, however, that the indemnification contained in
this Section 5 shall not apply to amounts paid in settlement of any Losses if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld, conditioned or delayed), nor
shall the Company be liable for any Losses to the extent they arise out of or are based upon a violation which occurs (A) in reliance upon and in conformity with written information furnished by a Subscriber, (B) in connection with any
failure of such person to deliver or cause to be delivered a prospectus made available by the Company in a timely manner, (C) as a result of offers or sales effected by or on behalf of any person by means of a freewriting prospectus (as defined
in Rule 405) that was not authorized in writing by the Company, or (D) in connection with any offers or sales effected by or on behalf of a Subscriber in violation of Section 5(b) of this Subscription Agreement. The
Company shall notify Subscriber promptly of the institution, threat or assertion of any proceeding arising from or in connection with the transactions contemplated by this Section 5 of which the Company is aware. Such
indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive the transfer of the Subscribed Shares by Subscriber. 

d. If the total number of shares of Common Stock that the Subscriber and any other person(s) intend to include in an
underwritten offering exceeds the number of shares of Common Stock that can be sold in an underwritten offering without being likely to have an adverse effect on the price, timing or distribution of shares of the Common Stock offered or the market
for the shares of Common Stock, then the shares of Common Stock to be included in such offering shall include the number of shares of Common Stock that the managing underwriter of the offering advises the Company can be sold without having such
adverse effect, with such number to be allocated (i) first, to the Company or other party or parties requesting or initiating such registration or to any other holder of securities of the Company having rights of registration pursuant to an
existing registration rights agreement and (ii) second, by the Subscriber who has requested participation in such underwritten offering and by the other holders of shares of Common Stock with registration rights entitling them to participate in
such underwritten offering, allocated among the Subscriber, the Other Subscribers and other holders pro rata on the basis of the number of shares of Common Stock proposed to be sold by each applicable holder in such underwritten offering (based, for
each such participant, on the percentage derived by dividing (x) the number of shares of Common Stock proposed to be sold by such participant in such underwritten offering by (y) the aggregate number of shares of Common Stock proposed to
be sold by all participants in such underwritten offering) or in such manner as they may agree. 

  
 13 

 e. Subscriber shall, severally and not jointly with any Other Subscriber,
indemnify and hold harmless the Company, its directors, officers, agents and employees, and each person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), to the fullest
extent permitted by applicable law, from and against all Losses, as incurred, arising out of or based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any prospectus included in the Registration
Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make
the statements therein (in the case of any prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading to the extent, but only to the extent, that such untrue statements or
omissions are based upon information regarding Subscriber furnished in writing to the Company by Subscriber expressly for use therein; provided, however, that the indemnification contained in this Section 5 shall not apply
to amounts paid in settlement of any Losses if such settlement is effected without the consent of Subscriber (which consent shall not be unreasonably withheld, conditioned or delayed). In no event shall the liability of any Subscriber be greater in
amount than the dollar amount of the net proceeds received by Subscriber upon the sale of the Subscribed Shares giving rise to such indemnification obligation. Subscriber shall notify the Company promptly of the institution, threat or assertion of
any proceeding arising from or in connection with the transactions contemplated by this Section 5 of which Subscriber is aware of which Subscriber shall seek indemnification under this Subscription Agreement; provided that
the failure by Subscriber to give such notice shall not relieve the Company of its indemnification obligations hereunder, except to the extent that the failure to give such notice is materially prejudicial to the Company’s ability to
defend such claim or litigation. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive the transfer of the Subscribed Shares by Subscriber. 

f. Any person or entity entitled to indemnification herein 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 not impair any person’s or entity’s right to indemnification hereunder to the extent such failure has not 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 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. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so
paid by the indemnifying party pursuant to the terms of such settlement), which settlement shall not include a statement or admission of fault and culpability on the part of such indemnified party, and which settlement shall include as an
unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation. 

g. If the indemnification provided under this Section 5 from the indemnifying party is unavailable or
insufficient to hold harmless an indemnified party in respect of any Losses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a
result of such Losses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations; provided, however, that the liability of the
Subscriber shall be limited to the net proceeds received by Subscriber from the sale of Subscribed Shares giving rise to such indemnification obligation. The relative fault of the indemnifying party and indemnified party shall be determined by
reference to, 

  
 14 

 
among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by (or
not made by, in the case of an omission), or relates to information supplied by (or not supplied by, in the case of an omission), such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative
intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the Losses shall be deemed to include, subject to the limitations set forth in this Section 5, any
legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be
entitled to contribution pursuant to this Section 5(g) from any person or entity who was not guilty of such fraudulent misrepresentation. 

h. For purposes of this Section 5 of this Subscription Agreement, (i) “Subscribed Shares” shall mean, as of any
date of determination, the Subscribed Shares (as defined in the recitals to this Subscription Agreement) and any other equity security issued or issuable with respect to the Subscribed Shares by way of share split, dividend, distribution,
recapitalization, merger, exchange, or replacement, and (ii) “Subscriber” shall include any affiliate of the Subscriber to which the rights under this Section 5 shall have been duly assigned. 

6. Termination. This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and
obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earlier to occur of (a) such date and time as the Merger Agreement is terminated in accordance with its
terms, (b) upon the mutual written agreement of the Company and the Subscriber to terminate this Subscription Agreement, (c) if, on the Closing Date of the Transaction, any of the conditions to Closing set forth in
Section 2 of this Subscription Agreement have not been satisfied as of the time required hereunder to be so satisfied or waived (to the extent a valid waiver is capable of being issued) by the party entitled to grant such
waiver and, as a result thereof, the transactions contemplated by this Subscription Agreement are not consummated, or (d) 11:59 p.m. prevailing Eastern time on July 31, 2021 (the “Outside Date”) if the Closing shall not have
occurred prior to such time; provided, that nothing herein will relieve any party from liability for any willful breach hereof (including, for the avoidance of doubt, Subscriber’s or the Company’s willful breach of
Section 2(c) of this Subscription Agreement with respect to its representations, warranties and covenants as of the date of the Closing) prior to the time of termination, and each party will be entitled to any remedies at
law or in equity to recover losses, liabilities or damages arising from such breach. The Company shall notify Subscriber of the termination of the Merger Agreement promptly after the termination thereof. 

7. Miscellaneous. 

a. All notices, requests, demands, claims, and other communications hereunder shall be in writing. Any notice, request, demand,
claim, or other communication hereunder shall be deemed duly given (i) when delivered personally to the recipient, (ii) when sent by electronic mail, on the date of transmission to such recipient; provided, that such notice, request,
demand, claim or other communication is also sent to the recipient pursuant to clauses (i), (iii) or (iv) of this Section 7(a), (iii) one Business Day after being sent to the recipient by reputable overnight courier
service (charges prepaid), or (iv) four (4) Business Days after being mailed to the recipient by certified or registered mail, return receipt requested and postage prepaid, and, in each case, addressed to the intended recipient at its address
specified on the signature page hereof or to such electronic mail address or address as subsequently modified by written notice given in accordance with this Section 7(a). 

b. Subscriber acknowledges that the Company and the Placement Agent will rely on the acknowledgments, understandings,
agreements, representations and warranties contained in this Subscription Agreement. Prior to the Closing, Subscriber agrees to promptly notify the Company and the Placement Agent if it becomes aware that any of the acknowledgments, understandings,
agreements, representations and warranties of Subscriber set forth herein are no longer accurate in all material respects. 

  
 15 

 
The Company acknowledges that Subscriber and others (including Placement Agent) will rely on the acknowledgments, understandings, agreements, representations and warranties contained in this
Subscription Agreement. Prior to the Closing, the Company agrees to promptly notify Subscriber if it becomes aware that any of the acknowledgments, understandings, agreements, representations and warranties of the Company set forth herein are no
longer accurate in all material respects. 
 c. Each of the Company and Subscriber is irrevocably authorized to produce this
Subscription Agreement or a copy hereof to any interested party in any administrative or legal proceeding or official inquiry with respect to the matters covered hereby. 

d. Each party hereto shall pay all of its own expenses in connection with this Subscription Agreement and the transactions
contemplated herein. 
 e. Neither this Subscription Agreement nor any rights that may accrue to Subscriber hereunder (other
than the Subscribed Shares acquired hereunder, if any) may be transferred or assigned. Neither this Subscription Agreement nor any rights that may accrue to the Company hereunder may be transferred or assigned (provided, that, for the avoidance of
doubt, the Company may transfer the Subscription Agreement and its rights hereunder solely in connection with the consummation of the Transaction). Notwithstanding the foregoing, Subscriber may assign its rights and obligations under this
Subscription Agreement: (i) to one or more of its affiliates (including other investment funds or accounts managed or advised by the investment manager who acts on behalf of the Subscriber or affiliate) or, (ii) with the Company’s
prior written consent, to another person, provided that no such assignment shall relieve Subscriber of its obligations hereunder if any such assignee fails to perform such obligations, unless the Company has given its prior written consent to such
relief and such assignee agrees in writing to be bound by the terms hereof. 
 f. All the agreements, representations and
warranties made by each party hereto in this Subscription Agreement shall survive the Closing. 
 g. The Company may request
from Subscriber such additional information as the Company may reasonably deem necessary to evaluate the eligibility of Subscriber to acquire the Subscribed Shares, and Subscriber shall provide such information as may be reasonably requested, to the
extent readily available and to the extent consistent with its internal policies and procedures provided that Company agrees to keep any such information provided by Subscriber confidential. 

h. This Subscription Agreement may not be amended, modified, waived or terminated except by an instrument in writing, signed by
the party against whom enforcement of such modification, waiver, or termination is sought. No consideration (other than reimbursement of legal fees) shall be offered or paid to any Person to amend or consent to a waiver or modification of any
provision of this Subscription Agreement or any Other Subscription Agreement unless the same consideration also is offered to all of the parties thereto (as the case may be). From the date hereof and until the Closing, the Company shall not be
permitted to receive any consideration from any Other Subscriber that is not otherwise contemplated in such Other Subscription Agreement as in effect as of the date hereof in order to, directly or indirectly, induce the Company or any Subsidiary
(i) to treat such Other Subscriber in a manner that is more favorable than the Subscriber, or (ii) to treat the Subscriber in a manner that is less favorable than any Other Subscriber; provided, however, that the determination of whether
the Subscriber has been treated more or less favorably than any Other Subscriber shall disregard any other securities (other than the Subscribed Shares) of the Company purchased by the Subscriber or Other Subscriber, respectively. 

i. This Subscription Agreement constitutes the entire agreement, and supersedes all other prior agreements, understandings,
representations and warranties, both written and oral, among the parties, with respect to the subject matter hereof, except that any confidentiality agreement with respect to Subscriber or its affiliates shall remain in full force and effect. 

j. Benefit 

(i) Except as otherwise provided herein, this Subscription Agreement shall be binding upon, and inure to the benefit of the
parties hereto and their heirs, executors, administrators, successors, legal 

  
 16 

 
representatives, and permitted assigns, and the agreements, representations, warranties, covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon, such
heirs, executors, administrators, successors, legal representatives and permitted assigns. 
 (ii) The parties hereto agree
that the Placement Agent is an express third-party beneficiary of its express rights in Section 3, Section 4, Section 7(h) and this Section 7(j)
of this Subscription Agreement. Each of the parties hereto shall be entitled to seek and obtain equitable relief, without proof of actual damages, including an injunction or injunctions or order for specific performance to prevent breaches of this
Subscription Agreement and to enforce specifically the terms and provisions of this Subscription Agreement to cause Subscriber to fund the Purchase Price and cause the Closing to occur if the conditions in Section 2(c) this
Subscription Agreement have been satisfied or, to the extent permitted by applicable law, waived. Each party hereto further agrees that the none of the parties hereto or the Placement Agent shall be required to obtain, furnish or post any bond or
similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 7(j), and each party hereto irrevocably waives any right it may have to require the obtaining, furnishing or
posting of any such bond or similar instrument. 
 k. If any provision of this Subscription Agreement shall be invalid,
illegal or unenforceable, the validity, legality or enforceability of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect so long as this
Subscription Agreement as so modified continues to express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question
does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations
to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s). Prior to or at the Closing, Subscriber shall
deliver to the Company a duly completed and executed Internal Revenue Service Form W-9 or appropriate Form W-8. 

l. This Subscription Agreement may be executed and delivered in one or more counterparts (including by facsimile or electronic
mail (including .pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com) or other transmission method) and by different parties in separate counterparts, with the same effect as if all parties
hereto had signed the same document. All counterparts so executed and delivered shall be construed together and shall constitute one and the same agreement. 

m. Remedies. 

(i) The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Subscription
Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Subscription Agreement and to
enforce specifically the terms and provisions of this Subscription Agreement, this being in addition to any other remedy to which such party is entitled at law, in equity, in contract, in tort or otherwise. 

(ii) Each of the parties hereto shall be entitled to seek and obtain equitable relief, without proof of actual damages,
including an injunction or injunctions or order for specific performance to prevent breaches of this Subscription Agreement and to enforce specifically the terms and provisions of this Subscription Agreement to cause Subscriber to fund the Purchase
Price and cause the Closing to occur if the conditions in Section 2(c) this Subscription Agreement have been satisfied or, to the extent permitted by applicable law, waived. The parties hereto further agree (i) to
waive any requirement for the security or posting of any bond in connection with any such equitable remedy, (ii) not to assert that a remedy of specific enforcement pursuant to this paragraph (m) is unenforceable, invalid, contrary to
applicable law or inequitable for any reason and (iii) to waive any defenses in any action for specific 

  
 17 

 
performance, including the defense that a remedy at law would be adequate. In any dispute arising out of or related to this Subscription Agreement, or any other agreement, document, instrument or
certificate contemplated hereby, or any transactions contemplated hereby or thereby, the applicable adjudicating body shall award to the prevailing party, if any, the costs and attorneys’ fees reasonably incurred by the prevailing party in
connection with the dispute and the enforcement of its rights under this Subscription Agreement or any other agreement, document, instrument or certificate contemplated hereby and, if the adjudicating body determines a party to be the prevailing
party under circumstances where the prevailing party won on some but not all of the claims and counterclaims, the adjudicating body may award the prevailing party an appropriate percentage of the costs and attorneys’ fees reasonably incurred by
the prevailing party in connection with the adjudication and the enforcement of its rights under this Subscription Agreement or any other agreement, document, instrument or certificate contemplated hereby or thereby. 

n. This Subscription Agreement shall be governed by, and construed in accordance with, the laws of the State of New York,
without regard to the principles of conflicts of laws that would otherwise require the application of the law of any other state. 

o. EACH PARTY HEREBY WAIVES ITS RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING
OUT OR RELATED TO THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY IN ANY ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY OR ANY AFFILIATE OF ANY OTHER SUCH PARTY, WHETHER WITH
RESPECT TO CONTRACT CLAIMS, TORT CLAIMS OR OTHERWISE. THE PARTIES AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A
TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS SUBSCRIPTION AGREEMENT OR ANY PROVISION HEREOF. THIS WAIVER
SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS SUBSCRIPTION AGREEMENT. 
 p.
The parties agree that all disputes, legal actions, suits and proceedings arising out of or relating to this Subscription Agreement must be brought exclusively in the state courts of New York or in the federal courts located in the state and county
of New York (collectively the “Designated Courts”). Each party hereby consents and submits to the exclusive jurisdiction of the Designated Courts. No legal action, suit or proceeding with respect to this subscription agreement may
be brought in any other forum. Each party hereby irrevocably waives all claims of immunity from jurisdiction and any objection which such party may now or hereafter have to the laying of venue of any suit, action or proceeding in any Designated
Court, including any right to object on the basis that any dispute, action, suit or proceeding brought in the Designated Courts has been brought in an improper or inconvenient forum or venue. Each of the parties also agrees that delivery of any
process, summons, notice or document to a party hereof in compliance with Section 7(a) of this Subscription Agreement shall be effective service of process for any action, suit or proceeding in a Designated Court with
respect to any matters to which the parties have submitted to jurisdiction as set forth above. 
 q. This Subscription
Agreement may only be enforced against, and any claim, action, suit or other legal proceeding based upon, arising out of, or related to this Subscription Agreement, or the negotiation, execution or performance of this Subscription Agreement, may
only be brought against the entities that are expressly named as parties hereto and then only with respect to the specific obligations set forth herein with respect to such party. No past, present or future director, officer, employee, incorporator,
manager, member, partner, stockholder, affiliate, agent, attorney or other representative of any party hereto or of any affiliate of any party hereto, or any of their successors or permitted assigns, shall have any liability for any obligations

  
 18 

 
or liabilities of any party hereto under this Subscription Agreement or for any claim, action, suit or other legal proceeding based on, in respect of or by reason of the transactions contemplated
hereby. 
 r. The Company shall, by 9:00 a.m., New York City time, on the first (1st) business day immediately following the
date of this Subscription Agreement, issue one or more press releases or file with the Commission a Current Report on Form 8-K (collectively, the “Disclosure Document”) disclosing, to the
extent not previously publicly disclosed, all material terms of the transactions contemplated hereby, the Transaction and any other material, nonpublic information that the Company has provided to Subscriber at any time prior to the filing of the
Disclosure Document. From and after the issuance of the Disclosure Document, Subscriber shall not be in possession of any material, non-public information received from the Company or any of its officers,
directors or employees or the Placement Agent. In addition, effective upon the filing of the Disclosure Document, the Company acknowledges and agrees that any and all confidentiality or similar obligations under any agreement, whether written or
oral, between the Company, any of its Subsidiaries or any of their respective officers, directors, affiliates, employees or agents, on the one hand, and Subscriber or any of its affiliates, on the other hand, shall terminate. Notwithstanding the
foregoing, the Company shall not publicly disclose the name of Subscriber or any affiliate or investment advisor of Subscriber, or include the name of Subscriber or any affiliate or investment advisor of Subscriber in any press release or in any
filing with the Commission or any regulatory agency or trading market, without the prior written consent (including by e-mail) of Subscriber, except as required by the federal securities laws, rules or
regulations and to the extent such disclosure is required by other laws, rules or regulations, at the request of the staff of the Commission or regulatory agency or under New York Stock Exchange regulations, in which case the Company shall provide
Subscriber with prior written notice (including by e-mail) of such permitted disclosure, and shall reasonably consult with Subscriber regarding such disclosure. Subject to the limitations of Section 8(a)
hereof, Subscriber hereby consents to the publication and disclosure in (x) any Form 8-K filed by the Company with the Commission in any filing with the Commission made in connection with the Merger
Agreement and the Transaction, including any proxy statement, prospectus or registration statement related thereto or any other filing with the Commission pursuant to applicable securities laws, and (y) any other documents or communications,
including press-releases, provided by the Company in connection with the Transaction, of Subscriber’s name and identity and the nature of Subscriber’s commitments, arrangements and understandings under and relating to this Subscription
Agreement and, if deemed required or appropriate by the Company, a copy of this Subscription Agreement. 
 s. The obligations
of Subscriber under this Subscription Agreement and the Other Subscribers under each Other Subscription Agreement, respectively, are several and not joint, and the Subscriber shall not be responsible in any way for the performance of the obligations
of any Other Subscriber under any Other Subscription Agreement. Nothing contained herein or in any Other Subscription Agreement, and no action taken by Subscriber or any Other Subscriber pursuant hereto or thereto, shall be deemed to constitute the
Subscriber and the Other Subscribers as, and the Company acknowledges that the Subscriber and the Other Subscribers do not so constitute, a partnership, an association, a joint venture or any other kind of group or entity, or create a presumption
that the Subscriber and the Other Subscribers are in any way acting in concert or as a group or entity, and the Company shall not assert any such claim with respect to such obligations or the transactions contemplated by this Subscription Agreement
or any Other Subscription Agreement or any matters, and the Company acknowledges that the Subscriber and the Other Subscribers are not acting in concert or as a group, and the Company shall not assert any such claim, with respect to such obligations
or the transactions contemplated by the Transaction Documents. The decision of the Subscriber to purchase Subscribed Shares pursuant to this Subscription Agreement has been made by the Subscriber independently of any Other Subscriber. The Subscriber
acknowledges that no Other Subscriber has acted as agent for the Subscriber in connection with the Subscriber making its investment hereunder and that no Other Subscriber will be acting as agent of the Subscriber in connection with monitoring the
Subscriber’s investment in the Subscribed Shares or enforcing its rights under this Subscription Agreement. The Company the Subscriber confirm that Subscriber has independently participated with the Company and its Subsidiaries in the
negotiation of the transaction contemplated hereby with the advice of its own counsel 

  
 19 

 
and advisors. Subscriber shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Subscription Agreement, and it shall not
be necessary for any Other Subscriber to be joined as an additional party in any proceeding for such purpose. 
 8. Additional Agreements.

 a. Neither the Company nor any of its affiliates and subsidiaries (if any) (collectively, the “Company
Group”) shall identify, or permit any of its employees, agents or representatives to identify, the Subscriber (whether in connection with the Company or in the Subscriber’s capacity as an investor in the Company) in any written or oral
public communications or issue any press release or other disclosure of the Subscriber’s name or the name of any of its affiliates, or any derivative of any of the foregoing names (collectively, the “Investor Names”), in each
case except (i) the Registration Statement, (ii) as authorized in writing by the Subscriber in each such instance (electronic mail to suffice) or (iii) as required by applicable law, legal process or regulatory request
(“Applicable Law”); provided, that such disclosing member of the Company Group as soon as practicable notifies the Subscriber of such requirement (except where prohibited by Applicable Law ) so that the Subscriber (or its applicable
affiliate) may seek a protective order or other appropriate remedy prior to such disclosure. Notwithstanding the foregoing, the Company may make disclosures to an auditor or governmental or regulatory authority pursuant to any routine investigation,
inspection, examination or inquiry without providing the Subscriber with any notification thereof, unless the Subscriber is the subject of any such investigation, inspection, examination or inquiry (in which case the preceding sentence shall
govern).
