date of this Subscription Agreement, neither the Issuer nor the Company is a party to or subject to the provisions of any outstanding or unsatisfied judgment, order, writ, injunction, decree or award of any governmental authority (except if
generally applicable without the Issuer being named therein) that would, individually or in the aggregate, reasonably be expected to have an Issuer Material Adverse Effect. 

2.2.16    Other than to the Placement Agents, no broker, finder, or other financial consultant has acted on
behalf of or at the direction of the Issuer in connection with this Subscription Agreement or the transactions contemplated hereby in such a way as to create any liability on Subscriber. 

2.2.17    Neither the Issuer nor 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 of the Securities Act) in connection with any offer or sale of the Shares, and 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. 
 2.2.18    Except as would not
reasonably be expected to have an Issuer Material Adverse Effect, (i) the Issuer and its subsidiaries own or possess valid and adequate rights to use any and all patents, patent applications, trademarks, service marks, trade names, trademark
registrations, service mark registrations, copyrights, licenses and know-how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential information, systems or procedures)
used in or necessary for the conduct of their respective businesses as presently conducted and as described and as proposed to be conducted, in the SEC Documents, (ii) the conduct of their respective businesses does not conflict in any material
respect with any such rights of others, and (iii) the Issuer and its subsidiaries have not received any written notice of any claim of infringement, misappropriation or violation of, or conflict with, any intellectual property right of others.

 2.2.19    Since its date of incorporation, neither the Issuer nor, to the Issuer’s knowledge, any
of its representatives, have directly or indirectly paid, offered or promised to pay, or authorized or ratified the payment, directly or indirectly, of any monies or anything of value to any national, provincial, municipal or other government
official or any political party or candidate for political office for the purpose of influencing any act or decision of such official or of any governmental authority to obtain or retain business, or direct business to any person or to secure any
other improper benefit or advantage in each case in violation in any material respect any Anti-Corruption Laws (as defined in the Merger Agreement). The Issuer (x) has instituted policies and procedures designed to ensure compliance with the
Anti-Corruption Laws and other anti-bribery, anti-corruption and anti-money laundering laws in each jurisdiction in which the
Issuer operates and (y) has maintained such policies and procedures in force. To the Issuer’s 

  
 10 












 
knowledge, no government official nor any of his or her immediate family members is an officer or director or owns any securities of the Issuer. Since its date of incorporation, neither the
Issuer nor, to the Issuer’s knowledge, any of its representatives, has, or is presently or has agreed to become, engaged in any conduct that violates in any material respect any applicable Anti-Corruption Laws. Since its date of incorporation,
to the Issuer’s knowledge, the Issuer is not conducting and has not conducted, directly or indirectly, any business (including, without limitation, sales, reselling, licensing or sub-licensing
arrangements, funding, making payments, procuring, insurance or otherwise providing assistance or support in connection with operations, business or any other activity) with or for the direct or indirect benefit of or on behalf of any Sanctioned
Person (as defined in the Merger Agreement), nor otherwise violated any applicable Sanction (as defined in the Merger Agreement) or Ex-Im Law (as defined in the Merger Agreement). 

2.2.20    As of the date hereof, all representations and warranties of the Company that are contained in
the Merger Agreement are true and correct in all material respects, to the knowledge of the Issuer after due inquiry. 

3.    Settlement Date and Delivery; Closing Conditions. 

3.1.1    The closing of the Subscription contemplated hereby (the “Closing”) is contingent
upon the substantially concurrent consummation of the Transactions and shall occur immediately prior to and is conditional upon the subsequent occurrence of, consummation of the Transactions. Upon written notice from (or on behalf of) the Issuer to
Subscriber (the “Closing Notice”) at least five (5) Business Days prior to the date that the Issuer reasonably expects all conditions to the closing of the Transactions to be satisfied or waived (the “Expected Closing
Date”), Subscriber shall deliver to the Issuer, no later than two (2) Business Days prior to the Expected Closing Date, (x) the Purchase Price for the Shares by wire transfer of United States dollars in immediately available funds
to the account specified by the Issuer in the Closing Notice, such funds to be held by the Issuer in escrow until the Closing and (y) such information as is reasonably requested in the Closing Notice in order for the Issuer to issue the Shares
to Subscriber, including the legal name of the person in whose name the Shares are to be issued and a duly completed and executed Internal Revenue Service Form W-9 or an appropriate duly completed and executed
Internal Revenue Service Form W-8. If the Transactions are not consummated on or prior to the fifth (5th) Business Day after the Expected Closing Date, the Issuer shall return the Purchase Price (which shall
not include, for the avoidance of doubt, the accrual of any interest) to Subscriber by wire transfer of United States dollars in immediately available funds to an account specified by Subscriber. Notwithstanding such return, Subscriber shall remain
obligated to redeliver funds representing the Purchase Price to the Issuer following the Issuer’s delivery to Subscriber of a new Closing Notice. At the Closing, the Issuer shall deliver to Subscriber (i) the Shares in book entry form,
free and clear of any liens or other restrictions whatsoever (other than those arising under state or federal securities laws or as set forth herein or in any other agreement between the Issuer and the Subscriber), in the name of Subscriber (or its
nominee in accordance with its delivery instructions) and (ii) as soon as reasonably practical following the Closing, a copy of the records of the Issuer’s transfer agent showing the Subscriber (or such nominee or custodian) as the owner
of the Shares on and as of the Closing. For purposes of this Subscription Agreement, “Business Day” means a day other than a Saturday, Sunday, or other day on which commercial banks in New York, New York are authorized or required
by law to close. Upon delivery in book-entry form of the Shares to the Subscriber (or its nominee, if applicable), the Purchase Price may be released from escrow. 

  
 11 












 3.1.2    The obligations of the Issuer to consummate the
transactions contemplated hereunder are subject to the satisfaction (or waiver by the Issuer in writing) of the conditions that, at the Closing: 

(1)    all representations and warranties of the Subscriber contained in this Subscription Agreement shall
be true and correct in all material respects (other than representations and warranties that are qualified as to materiality which representations and warranties shall be true and correct in all respects) at and as of the Closing, and consummation
of the Closing shall constitute a reaffirmation by the Subscriber of each of the representations, warranties and agreements of such party contained in this Subscription Agreement as of the Closing; and 

(2)    Subscriber shall have performed or complied in all material respects with all agreements and
covenants required by this Subscription Agreement required to be performed or complied with at or prior to the Closing, except where the failure of such performance or compliance would not reasonably be expected to prevent, materially delay, or
materially impair the ability of the Subscriber to consummate the Closing. 
 3.1.3    The obligations of
the Subscriber to consummate the transactions contemplated hereunder are subject to the satisfaction (or waiver by the Subscriber in writing) of the conditions that, at the Closing: 

(1)    all representations and warranties of the Issuer contained in this Subscription Agreement shall be
true and correct in all material respects (other than representations and warranties that are qualified as to materiality or an Issuer Material Adverse Effect, which representations and warranties shall be true and correct in all respects) at and as
of the Closing, and consummation of the Closing shall constitute a reaffirmation of each of the applicable representations, warranties and agreements of the Issuer and the combined company contained in this Subscription Agreement as of the Closing;

 (2)    the Issuer shall have performed or complied in all material respects with all agreements and
covenants required by this Subscription Agreement required to be performed or complied with 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 Issuer to consummate the Closing; 
 (3)    no suspension
of the qualification of the Common Stock for offering or sale or trading in any jurisdiction, or initiation or threatening of any proceedings for any such purposes shall have occurred, and the Shares shall have been approved for listing on Nasdaq
(subject to official notice of issuance); and 
 (4)    the Merger Agreement shall not have been amended
to, and there shall have been no waiver or modification to the Merger Agreement that would, materially and adversely affect the undersigned relative to the economic benefits that the Subscriber would reasonably expect to receive under this
Subscription Agreement without the Subscriber’s prior written consent. 

  
 12 












 3.1.4    The obligations of each of the Issuer and the
Subscriber to consummate the transactions contemplated hereunder are subject to the satisfaction of the conditions that, at the Closing: 

(1)    no governmental authority of competent jurisdiction shall have enacted, issued, promulgated,
enforced or entered any law, rule, regulation, judgment, decree, executive order or award after the date hereof which is then in effect and has the effect of making the Subscription illegal or otherwise prohibiting consummation of the Subscription;

 (2)    all conditions precedent to the closing of the Transactions set forth in the Merger Agreement,
including all necessary approvals of the Issuer’s stockholders and regulatory approvals, if any, shall have been satisfied or waived as determined by the applicable parties to the Merger Agreement (other than those conditions that may only be
satisfied at the closing of the Transactions, but subject to the satisfaction or waiver of such conditions as of the closing of the Transactions); and 

(3)    the Transactions shall have been or will be consummated concurrently with the Closing. 

4.    Registration Statement. 

4.1    The Issuer agrees that, prior to the Closing of the Transactions (the “Filing Date”), the Issuer
will file with the Commission (at the Issuer’s sole cost and expense) a registration statement (the “Registration Statement”) registering the resale of the Shares eligible for registration (the “Registrable
Securities”), and the Issuer shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof (such date, the “Effectiveness Date”);
provided, however, that the Issuer’s obligations to include the Registrable Securities in the Registration Statement are contingent upon Subscriber furnishing a completed and executed selling shareholders questionnaire in
customary form to the Issuer that contains the information required by Commission rules for a Registration Statement regarding Subscriber, the securities of the Issuer held by Subscriber, and the intended method of disposition of the Registrable
Securities to effect the registration of the Registrable Securities, and Subscriber shall execute such documents in connection with such registration as the Issuer may reasonably request that are customary of a selling stockholder in similar
situations, including providing that the Issuer shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement during any customary blackout or similar period or as permitted hereunder; provided that 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 Shares. Any failure by
the Issuer to file the Registration Statement by the Filing Date or to effect such Registration Statement by the Effectiveness Date shall not otherwise relieve the Issuer of its obligations to file or effect the Registration Statement as set forth
above in this Section 4. Unless required under applicable laws and Commission rules, in no event shall the Subscriber be identified as a statutory underwriter in the Registration Statement; provided, that if the Subscriber
is required to be so identified as a statutory underwriter in the Registration Statement, the Subscriber will have an opportunity to withdraw its Registrable Securities from the Registration Statement. 

4.2    In the case of the registration effected by the Issuer pursuant to this Subscription Agreement, the Issuer shall,
upon reasonable request, inform Subscriber as to the status of such registration. At its expense, the Issuer shall: 

  
 13 












 4.2.1    except for such times as the Issuer is
permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, use its commercially reasonable efforts to keep such registration, and any qualification, exemption, or compliance under state securities laws which
the Issuer determines to obtain, continuously effective with respect to Subscriber, and to keep the applicable Registration Statement or any subsequent shelf registration statement free of any material misstatements or omissions, until the earliest
of the following: (i) Subscriber ceases to hold any Registrable Securities; (ii) the date all Registrable Securities held by Subscriber may be sold without restriction under Rule 144, including without limitation, any volume and manner of
sale restrictions which may be applicable to affiliates under Rule 144 and without the requirement for the Issuer to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable) and
(iii) three years from the date of the effectiveness of the Registration Statement; 

4.2.2    advise Subscriber as expeditiously as reasonably possible (and not later than within three
(3) Business Days): 
 (a)    when a Registration Statement or any post-effective amendment thereto
has become effective; 
 (b)    after it shall receive notice or obtain knowledge thereof, of the
issuance by the Commission of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose; 

(c)    of the receipt by the Issuer of any notification with respect to the suspension of the
qualification of the Registrable Securities included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and 

(d)    subject to the provisions in this Subscription Agreement, of the occurrence of any event that
requires the making of any changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the
statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading. 

Notwithstanding anything to the contrary set forth herein, the Issuer shall not, when so advising Subscriber of such events, provide
Subscriber with any material, nonpublic information regarding the Issuer other than to the extent that providing notice to Subscriber of the occurrence of the events listed in (a) through (d) above may constitute material, nonpublic information
regarding the Issuer; Subscriber hereby consents to receipt of any material, non-public information with respect to the occurrence of the events listed in (a) through (d) above; 

4.2.3    use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of
any Registration Statement as soon as reasonably practicable; 
 4.2.4    upon the occurrence of any event contemplated
in Section 4.2.2(d), except for such times as the Issuer is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, the Issuer shall use its commercially
reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to 

  
 14 












 
such Registration Statement or a supplement to the related prospectus, or file any other required document, so that, as thereafter delivered to purchasers of the Registrable Securities included
therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and 

4.2.5    use its commercially reasonable efforts to cause all Shares to be listed on each securities
exchange or market, if any, on which the Issuer’s Common Stock is then listed. 
 4.3    Notwithstanding anything
to the contrary in this Subscription Agreement, if the Commission prevents the Issuer from including in the Registration Statement any or all of the Shares due to limitations on the use of Rule 415 of the Securities Act for the resale of the Shares
by the Subscriber, the Registration Statement shall register for resale such number of Shares which is equal to the maximum number of Shares as is permitted by the Commission. In such event, the number of Shares to be registered for each selling
stockholder named in the Registration Statement shall be reduced pro rata among all such selling stockholders and as promptly as practicable after being permitted to register additional Shares under Rule 415 under the Securities Act, the Issuer
shall use commercially reasonable efforts to amend the Registration Statement or file a new Registration Statement to register such Shares not included in the initial Registration Statement. 

4.4    Notwithstanding anything to the contrary in this Subscription Agreement, the Issuer shall be entitled to delay or
postpone the effectiveness of the Registration Statement, and from time to time to require Subscriber not to sell under the Registration Statement or to suspend the effectiveness thereof, if it determines that in order for the Registration Statement
not to contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements contained therein not misleading, (i) an amendment thereto would be needed to include information that would at that time
not otherwise be required in a current, quarterly, or annual report under the Exchange Act, (ii) the negotiation or consummation of a transaction by Issuer or its subsidiaries is pending or an event has occurred, which negotiation, consummation
or event Issuer’s board of directors reasonably believes would require additional disclosure by Issuer in the Registration Statement of material information that the Issuer 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 Issuer’s board of directors to cause the Registration Statement to fail to comply with
applicable disclosure requirements or (iii) in the good faith judgment of the majority of the Issuer’s board of directors, such filing or effectiveness or use of such Registration Statement, would be seriously detrimental to the Issuer and
the majority of the Issuer’s board of directors concludes as a result that it is essential to defer such filing (each such circumstance, a “Suspension Event”); provided, however, that the Issuer may not delay or
suspend the Registration Statement on more than three (3) occasions or for more than sixty (60) consecutive calendar days, or more than ninety (90) total calendar days, in each case during any twelve (12) month period. Upon
receipt of any written notice from the Issuer of the happening of any Suspension Event 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 (a) it will immediately discontinue offers and sales of the Shares under the Registration Statement until Subscriber receives copies of a supplemental or amended prospectus (which the Issuer 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 Issuer that it may resume such offers and sales, and
(b) it will maintain the confidentiality of any information included in such written notice delivered by the Issuer as required by law. If so directed by the Issuer, Subscriber will deliver to the Issuer or, in Subscriber’s sole discretion
destroy, all copies of the prospectus covering the 

  
 15 












 
Shares in Subscriber’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Shares shall not apply (1) 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 (2) to copies stored electronically on archival servers as a result of automatic data back-up. 

5.    Termination. Except for the provisions of this Section 5 and
Section 6, which shall survive any termination hereunder, 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 earliest to occur of (i) the Merger Agreement is validly terminated in accordance with its terms, (ii) upon the mutual written agreement of the Company and
each of the parties hereto to terminate this Subscription Agreement and (iii) the date that is nine (9) months from the date hereof, if the Closing has not occurred by such date or, if the Merger Agreement Termination Date (as defined in
the Merger Agreement) is extended by the parties thereto, twelve (12) months from the date hereof; provided, that nothing herein will relieve any party from liability for any willful breach hereof 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 Issuer shall promptly notify Subscriber of the termination of the Merger Agreement promptly after the
termination of such agreement (if applicable), and any monies paid by the Subscriber to the Issuer in connection herewith shall promptly (and in any event within two (2) Business Days) following a termination be returned to the Subscriber
without any deduction for or on account of any tax withholding, charges or set-off, in each case, to the extent permitted by law. 

6.    Miscellaneous. 

6.1    Further Assurances. The parties hereto shall execute and deliver such additional documents and take such additional
actions as the parties reasonably may deem to be practical and necessary in order, or cause to be taken, all things necessary, proper or advisable to consummate the Subscription as contemplated by this Subscription Agreement on the terms and
conditions described herein no later than immediately prior to the Closing. 
 6.1.1    Subscriber
acknowledges that the Issuer, the Company, and others will rely on the acknowledgments, understandings, agreements, representations, and warranties made by Subscriber contained in this Subscription Agreement. Prior to the Closing, Subscriber agrees
to promptly notify the Issuer and the Company if any of the acknowledgments, understandings, agreements, representations, and warranties set forth herein are no longer accurate in all material respects. 

6.1.2    Each of the Issuer, Subscriber, and the Company is entitled to rely upon this Subscription
Agreement and 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. 

6.1.3    The Issuer may request from Subscriber such additional information as the Issuer may reasonably
deem necessary to evaluate the eligibility of Subscriber to acquire the Shares, and Subscriber shall promptly 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 the Issuer expressly agrees to keep any such information provided by the Subscriber confidential, except as required by the applicable securities laws or pursuant to proceedings of regulatory authorities. 

  
 16 












 6.1.4    Subscriber shall pay all of its own expenses in
connection with this Subscription Agreement and the transactions contemplated herein. 
 6.1.5    Each of
Subscriber and the Issuer shall take, or cause to be taken, all actions and do, or cause to be done, all things necessary, proper, or advisable to consummate the transactions contemplated by this Subscription Agreement on the terms and conditions

 6.3    Entire Agreement. 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, including any commitment letter entered into relating to the
subject matter hereof. 
 6.4    Modifications; Amendments; Waivers. This Subscription Agreement may not be
amended, modified, supplemented, or waived (i) except by an instrument in writing, signed by the party against whom enforcement of such amendment, modification, supplement, or waiver is sought and (ii) without the prior written consent of
the Company. No failure or delay of either party in exercising any right or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to
enforce such right or power, or any course of conduct, preclude any other or further exercise thereto or the exercise of any other right or power. 

6.5    Assignment. Neither this Subscription Agreement nor any rights, interests, or obligations that may accrue to
the parties hereunder (including Subscriber’s rights to purchase the Shares) may be transferred or assigned without the prior written consent of each of the Company and the other party hereto (other than the Shares acquired hereunder and then
only in accordance with this Subscription Agreement). 
 6.6    Benefit. 

6.6.1    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 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. The parties hereto agree that each of the Company and its subsidiaries are express third-party beneficiaries
(the “Beneficiaries”) of this Subscription Agreement. Each of the parties hereto acknowledge and agree that (i) each of the Beneficiaries 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 the Issuer to cause, or directly
cause, Subscriber to fund the Purchase Price and cause the Closing to occur substantially concurrently with the Transactions, and (ii) without in any way limiting the foregoing, the Company is an express-third party beneficiary of Sections
3 (Closing), 5, (Termination), 6.1 (Further Assurances), 6.4 (Modifications and Amendments), 6.5 (Assignment), 6.11 (Remedies) and 7.2 (Cleansing Statement;
Disclosure ) and 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 its rights referenced therein. Each party
hereto further agrees that each of the Beneficiaries is an express third-party beneficiary of this Section 6.6 and that none of the parties hereto or any of the Beneficiaries 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 6.6.1, and each party hereto irrevocably waives any right it may have to require the obtaining,
furnishing, or posting of any such bond of similar instrument. 

  
 18 












 6.6.2    Each of the Issuer and Subscriber acknowledges
and agrees that (i) this Subscription Agreement is being entered into in order to induce each of the parties to the Merger Agreement to execute and deliver the Merger Agreement and without the representations, warranties, covenants, and
agreements of the Issuer and Subscriber hereunder, the Company would not enter into the Merger Agreement, and (ii) each representation, warranty, covenant, and agreement of the Issuer and Subscriber hereunder is being made also for the benefit
of the Company and the Beneficiaries. 
 6.6.3    Each of the Issuer and Subscriber further acknowledge
and agree that the Placement Agents s are third-party beneficiaries of the representations and warranties of the Issuer and Subscriber contained in this Subscription Agreement. 

6.7    Governing Law. This Subscription Agreement, and any claim or cause of action hereunder based upon, arising
out of or related to this Subscription Agreement (whether based on law, in equity, in contract, in tort, or any other theory) or the negotiation, execution, performance, or enforcement of this Subscription Agreement, shall be governed by and
construed in accordance with the internal laws of the State of Delaware, including its statute of limitations, without giving effect to principles or rules of conflicts of law thereof to the extent they would require or permit the application of
laws or statute of limitations of another jurisdiction. 
 6.8    Consent to Jurisdiction; Waiver of Jury Trial.
Each of the parties irrevocably consents to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware; provided, that if subject matter jurisdiction over the matter that is the subject of the legal proceeding is
vested exclusively in the U.S. federal courts, such legal proceeding shall be heard in the U.S. District Court for the District of Delaware (together with the Court of Chancery of the State of Delaware, the “Chosen Courts”), in
connection with any matter based upon or arising out of this Subscription Agreement. Each party hereby waives, and shall not assert as a defense in any legal dispute, that (i) such person is not personally subject to the jurisdiction of the
Chosen Courts for any reason, (ii) such legal proceeding may not be brought or is not maintainable in the Chosen Courts, (iii) such person’s property is exempt or immune from execution, (iv) such legal proceeding is brought in an
inconvenient forum, or (v) the venue of such legal proceeding is improper. Each party hereby consents to service of process in any such proceeding in any manner permitted by Delaware law, further consents to service of process by nationally
recognized overnight courier service guaranteeing overnight delivery, or by registered or certified mail, return receipt requested, at its address specified pursuant to Section 6.2, and waives and covenants not to assert or
plead any objection which they might otherwise have to such manner of service of process. Notwithstanding the foregoing in this Section 6.8, a party may commence any action, claim, cause of action, or suit in a court other
than the Chosen Courts solely for the purpose of enforcing an order or judgment issued by the Chosen Courts. TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW WHICH CANNOT BE WAIVED, EACH OF THE PARTIES WAIVES ANY RIGHT TO TRIAL BY JURY ON ANY CLAIMS
OR COUNTERCLAIMS ASSERTED IN ANY LEGAL DISPUTE RELATING TO THIS SUBSCRIPTION AGREEMENT WHETHER NOW EXISTING OR HEREAFTER ARISING. IF THE SUBJECT MATTER OF ANY SUCH LEGAL DISPUTE IS ONE IN WHICH THE WAIVER OF JURY TRIAL IS PROHIBITED, NO PARTY SHALL
ASSERT IN SUCH LEGAL DISPUTE A NONCOMPULSORY COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS SUBSCRIPTION AGREEMENT. FURTHERMORE, NO PARTY SHALL SEEK TO CONSOLIDATE ANY SUCH LEGAL DISPUTE WITH A SEPARATE ACTION OR OTHER LEGAL PROCEEDING IN WHICH A
JURY TRIAL CANNOT BE WAIVED. 
 6.9    Severability. If any provision of this Subscription Agreement shall be
invalid, illegal, or unenforceable, the validity, legality, or enforceability of the remaining provisions of this 

  
 19 












 
Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect. 

6.10    No Waiver of Rights, Powers, and Remedies. No failure or delay by a party hereto in exercising any right,
power, or remedy under this Subscription Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power, or remedy of such party. No single or partial exercise of any right, power, or remedy under
this Subscription Agreement by a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power, or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right,
power, or remedy hereunder. The election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Subscription
Agreement shall entitle the party receiving such notice or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further
action in any circumstances without such notice or demand. 
 6.11    Remedies. 

6.11.1    The parties agree that the Issuer and the Beneficiaries would suffer irreparable damage if this
Subscription Agreement was not performed or the Closing is not consummated in accordance with its specific terms or was otherwise breached and that money damages or other legal remedies would not be an adequate remedy for any such damage. It is
accordingly agreed that the Issuer and each of the Beneficiaries shall be entitled to equitable relief, including in the form of an injunction or injunctions, to prevent breaches or threatened breaches of this Subscription Agreement and to enforce
specifically the terms and provisions of this Subscription Agreement in an appropriate court of competent jurisdiction as set forth in Section 6.8, this being in addition to any other remedy to which any party is entitled
at law or in equity, including money damages. The right to specific enforcement shall include the right of the Issuer and each of the Beneficiaries to cause the parties hereto to cause the transactions contemplated hereby to be consummated on the
terms and subject to the conditions and limitations set forth in this Subscription Agreement (including, for the avoidance of doubt, the right to directly enforce each of the covenants and agreements of Subscriber under this Subscription Agreement).
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
Section 6.11 is unenforceable, invalid, contrary to applicable law, or inequitable for any reason, and (iii) to waive any defenses in any action for specific performance, including the defense that a remedy at law
would be adequate. In connection with any Action for which any of the Beneficiaries is being granted an award of money damages, each of the Issuer and Subscriber agrees that such damages, to the extent payable by such party, shall include, without
limitation, damages related to the cash consideration that is or was to be paid to the Company and any Pre-Closing Holder under the Merger Agreement and/or in connection with this Subscription Agreement and
such damages are not limited to an award of out-of-pocket fees and expenses related to the Merger Agreement and/or this Subscription Agreement. 

6.11.2    The parties acknowledge and agree that this Section 6.11 is an integral
part of the transactions contemplated hereby and without that right, the parties hereto would not have entered into this Subscription Agreement. 

6.11.3    In any dispute arising out of or related to this Subscription Agreement, or any other agreement,
document, instrument, or certificate contemplated hereby, or any 

  
 20 












 
transactions contemplated hereby or thereby, the applicable adjudicating body shall award to the prevailing party, if any, the reasonable and documented out-of-pocket 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. 

6.12    Survival of Representations and Warranties. All representations and warranties made by the parties hereto
in this Subscription Agreement shall survive the Closing. For the avoidance of doubt, if for any reason the Closing does not occur prior to the consummation of the Transactions, all representations, warranties, covenants, and agreements of the
parties hereunder shall survive the consummation of the Transactions and remain in full force and effect. 

6.13    Headings and Captions. The headings and captions of the various subdivisions of this Subscription Agreement
are for convenience of reference only and shall in no way modify or affect the meaning or construction of any of the terms or provisions hereof. 

6.14    Counterparts. This Subscription Agreement may be executed in one or more counterparts, all of which when
taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other parties, it being understood that the parties need not sign the same counterpart. In
the event that any signature is delivered by facsimile transmission, email, or any other form of electronic delivery, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed)
with the same force and effect as if such signature page were an original thereof. 
 6.15    Construction. The
words “include,” “includes,” and “including” will be deemed to be followed by “without limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include
any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words “this Subscription Agreement,” “herein,”
“hereof,” “hereby,” “hereunder,” and words of similar import refer to this Subscription Agreement as a whole and not to any particular subdivision unless expressly so limited. The parties hereto
intend that each representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists
another representation, warranty, or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that such party hereto is in
breach of the first representation, warranty, or covenant. All references in this Subscription Agreement to numbers of shares, per share amounts, and purchase prices shall be appropriately adjusted to reflect any stock split, stock dividend, stock
combination, recapitalization, or the like occurring after the date hereof. 
 6.16    Mutual Drafting. This
Subscription Agreement is the joint product of the parties hereto and each provision hereof has been subject to the mutual consultation, negotiation, and agreement of the parties and shall not be construed for or against any party hereto. 

7.    Cleansing Statement; Disclosure. 

  
 21 












 7.1    The Issuer 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 (1) or more press releases or file with the Commission a Current Report on Form 8-K (collectively the
“Disclosure Document”) disclosing all material terms of the transactions contemplated hereby and by the Other Subscription Agreements and the Transactions and any other material, nonpublic information that the Issuer, the Company, any of
their respective subsidiaries or any of their respective officers, directors, employees, affiliates or agents has provided to the Subscriber at any time prior to the filing of such Disclosure Document. As of immediately following the filing of the
Disclosure Document, to the knowledge of the Issuer, the Subscriber shall not be in possession of any material, non-public information received from the Issuer, the Company, any of their respective
subsidiaries or any of their respective officers, directors, employees, affiliates or agents that is not disclosed in the Disclosure Document or in prior filings with the Commission. In addition, effective upon the filing of the Disclosure Document,
the Issuer acknowledges and agrees that any and all confidentiality obligations under any agreement, whether written or oral, between the Issuer or any of its agents, on the one hand, and the Subscriber or any of its affiliates, on the other hand,
shall terminate and be of no further force or effect. 
 7.2    Subscriber hereby consents to the publication and
disclosure in (i) the Form 8-K filed by the Issuer with the Commission in connection with the execution and delivery of the Merger Agreement, the Proxy Statement, or any other filing with the Commission
pursuant to applicable securities laws, in each case, as and (ii) to the extent required by the federal securities laws or, exchange rules, the Commission or any other securities authorities, and (ii) any other filings, documents or
communications provided by the Issuer or the Company to any governmental authority or to securityholders of the Issuer, in each case, as and to the extent required by applicable law or the Commission or any other governmental authority, 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 Issuer and/or the Company, a copy
of this Subscription Agreement. Subscriber will promptly provide any information reasonably requested by the Issuer and/ or the Company for any regulatory application or filing made or approval sought in connection with the Transactions (including
filings with the Commission). Notwithstanding anything in this Subscription Agreement to the contrary, the Issuer shall not (and shall cause the Company not to), without the prior written consent of the Subscriber, publicly disclose the name of the
Subscriber or any of its affiliates or advisers, or include the name of the Subscriber or any of its affiliates or advisers, in any press release or marketing materials. 

8.    Trust Account Waiver. Subscriber acknowledges that the Issuer has established a trust account containing the
proceeds of its initial public offering and from certain private placements (collectively, with interest accrued from time to time thereon, the “Trust Account”). Subscriber agrees that (i) it has no right, title, interest, or
claim of any kind in or to any monies held in the Trust Account, and (ii) it shall have no right of set-off or any right, title, interest, or claim of any kind (“Claim”) to, or to any
monies in, the Trust Account, in each case in connection with this Subscription Agreement, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account that it may have in connection with this Subscription Agreement;
provided, however, that nothing in this Section 8 shall be deemed to limit Subscriber’s right, title, interest, or claim to the Trust Account by virtue of such Subscriber’s record or beneficial
ownership of securities of the Issuer acquired by any means other than pursuant to this Subscription Agreement, including any redemption right with respect to any such securities of the Issuer. In the event Subscriber has any Claim against the
Issuer under this Subscription Agreement, Subscriber shall pursue such Claim solely against the Issuer and its assets outside the Trust Account and not against the property or any monies in the Trust Account. Subscriber agrees and acknowledges that
such waiver is material to this Subscription Agreement and has been specifically relied upon by the Issuer to induce the Issuer to enter into this Subscription Agreement and Subscriber further intends and understands such waiver to be valid,
binding, and enforceable under applicable law. In the 

  
 22 












 
event Subscriber, in connection with this Subscription Agreement, commences any action or proceeding which seeks, in whole or in part, relief against the funds held in the Trust Account or
distributions therefrom or any of the Issuer’s stockholders, whether in the form of monetary damages or injunctive relief, Subscriber shall be obligated to pay to the Issuer all of its legal fees and costs in connection with any such action in
the event that the Issuer prevails in such action or proceeding. 
 9.    Waiver of Sovereign Immunity. With
respect to the liability of Subscriber to perform its obligations under this Agreement, with respect to itself or its property, Subscriber: 

9.1    agrees that, for purposes of the doctrine of sovereign immunity, the execution, delivery, and performance by it of
this Agreement constitutes private and commercial acts done for private and commercial purposes; 
 9.2    agrees that,
should any proceedings be brought against it or its assets in any jurisdiction in relation to this Agreement or any transaction contemplated by this Agreement in accordance with the terms hereof, Subscriber is not entitled to any immunity on the
basis of sovereignty in respect of its obligations under this Agreement, and no immunity from such proceedings (including, without limitation, immunity from service of process from suit, from the jurisdiction of any court, from an order or
injunction of such court, or the enforcement of same against its assets) shall be claimed by or on behalf of such party or with respect to its assets; 

9.3    waives, in any such proceedings, to the fullest extent permitted by law, any right of immunity which it or any of
its assets now has or may acquire in the future in any jurisdiction; 
 9.4    subject to the terms and conditions
hereof, consents generally in respect of the enforcement of any judgment or award against it in any such proceedings to the giving of any relief or the issue of any process in any jurisdiction in connection with such proceedings (including, without
limitation, pre-judgment attachment, post judgment attachment, the making, enforcement, or execution against or in respect of any assets whatsoever irrespective of their use or intended use of any order or
judgment that may be made or given in connection therewith); and 
 9.5    specifies that, for the purposes of this
provision, “assets” shall be taken as excluding “premises of the mission” as defined in the Vienna Convention on Diplomatic Relations signed at Vienna, April 18, 1961, “consular premises” as defined in the Vienna
Convention on Consular Relations signed in 1963, and military property or military assets or property of the Subscriber.]1 

10.    Rule 144. From and after such time as the benefits of Rule 144 promulgated under the Securities Act or any
other similar rule or regulation of the Commission that may allow Subscriber to sell securities of the Issuer to the public without registration are available to holders of the Issuer’s common stock and for so long as the Subscriber holds
Shares, the Issuer agrees to use commercially reasonable efforts to: 
 10.1.1    make and keep public
information available, as those terms are understood and defined in Rule 144; 
 10.1.2    file with the
Commission in a timely manner all reports and other documents required of the Issuer under the Securities Act and the Exchange Act so long as the Issuer remains subject to such requirements and the filing of such reports and other documents is
required for the applicable provisions of Rule 144; and 
  

	1 	 Note to Draft: To be included for all sovereign wealth or similar investors. 



  
 23 












 10.1.3    furnish to Subscriber, promptly upon
Subscriber’s reasonable request, (i) a written statement by the Issuer, if true, that it has complied with the reporting requirements of Rule 144, the Securities Act, and the Exchange Act, (ii) a copy of the most recent annual or
quarterly report of the Issuer and such other reports and documents so filed by the Issuer, and (iii) such other information as may be reasonably requested to permit Subscriber to sell such securities pursuant to Rule 144 without registration.

 If in the opinion of counsel to the Issuer, it is then permissible to remove the restrictive legend from the Shares pursuant to Rule 144
under the Securities Act, then at Subscriber’s request, the Issuer will request its transfer agent to remove the legend set forth in Section 2.1.6. In connection therewith, if reasonably required by the Issuer’s
transfer agent, the Issuer will, at Issuer’s sole expense, reasonably promptly cause an opinion of counsel to be delivered to and maintained with its transfer agent, together with any other authorizations, certificates, and directions required
by the transfer agent from the Issuer or Subscriber that authorize and direct the transfer agent remove the restrictive legend from such Shares; provided, that, notwithstanding the foregoing, the Issuer will not be required to deliver any
such opinion, authorization, certificate, or direction if it reasonably believes that removal of the legend could result in or facilitate transfers of securities in violation of applicable law.
