 2.1.5. 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
understands and acknowledges that the historical financial information and forecasts regarding Semantix made available to Subscriber were based on financial information that is preliminary and subject to change based on the completion of the audit
of Semantix’s financial statements in accordance with International Financial Reporting Standards and the standards of the Public Company Accounting Oversight Board. Accordingly, Subscriber has sought such accounting, legal and tax advice as
Subscriber has considered necessary to make an informed investment decision. Subscriber acknowledges that Subscriber shall be responsible for any of Subscriber’s tax liabilities that may arise as a result of the transactions contemplated by
this Subscription Agreement, and that neither the Issuer, New Pubco nor Semantix has provided any tax advice or any other representation or guarantee regarding the tax consequences of the transactions contemplated by this Subscription Agreement.

 2.1.6. Alone, or together with any professional advisor(s), 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 Subscribed Shares. Subscriber acknowledges specifically that a possibility of total loss exists. 

2.1.7. 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 or any other securities laws of the United States or any other jurisdiction and that neither New Pubco or any other person is
required to register the Subscribed Shares except as set forth in Section 4 of this Subscription Agreement. Subscriber understands that the Subscribed Shares may not be resold, transferred, pledged or otherwise disposed of

solely outside the United States within the meaning of Regulation S under the Securities Act, (iii) pursuant to Rule 144 under the Securities Act (“Rule 144”), provided that all of the applicable conditions thereof (including

securities laws of the states and other jurisdictions of the United States and other applicable jurisdictions, and that the Subscribed Shares shall be subject to a legend to such effect (provided that such legends will be eligible for removal upon
compliance with the relevant resale provisions of Rule 144). Subscriber acknowledges that the Subscribed Shares will not be eligible for offer, resale, transfer, pledge or disposition pursuant to Rule 144A promulgated under the Securities Act.
Subscriber understands and agrees that the Subscribed Shares will be subject to the foregoing restrictions and, as a result, Subscriber may not be able to readily offer, resell, transfer, pledge or otherwise dispose the Subscribed Shares and may be

required to bear the financial risk of an investment in the Subscribed Shares for an indefinite period of time. Subscriber understands that it has been advised to consult independent legal
counsel prior to making any offer, resale, pledge or transfer of any of the Subscribed Shares. Subscriber has determined based on its own independent review and such professional advice as it deems appropriate that the Subscribed Shares are a
suitable investment for Subscriber, notwithstanding the substantial risks inherent in investing in or holding the Subscribed Shares. 

2.1.8. Subscriber understands, acknowledges and agrees that Subscriber is purchasing the Subscribed Shares directly from the
Issuer. Subscriber further acknowledges that there have been no representations, warranties, covenants or agreements made to Subscriber by the Issuer, New Pubco, Semantix, or any of their respective affiliates, control persons, officers, directors,
employees, agents or representatives, expressly or by implication, other than those representations, warranties, covenants and agreements expressly set forth in this Subscription Agreement. 

2.1.9. If Subscriber is or is acting on behalf of an employee benefit plan that is subject to Title I of the Employee
Retirement Income Security Act of 1974, as amended (“ERISA”), Subscriber represents and warrants that its acquisition and holding of the Subscribed Shares will not constitute or result in a
non-exempt prohibited transaction under Section 406 of ERISA, Section 4975 of the Internal Revenue Code of 1986, as amended (the “Code”), or any applicable other federal, state,
local, non-U.S. or other laws or regulations that are similar to such provisions of ERISA or the Code (collectively, “Similar Laws”). 

2.1.10. Subscriber acknowledges and agrees that Subscriber has received, reviewed and understood the offering materials made
available to it in connection with the Transactions and such information as Subscriber deems necessary in order to make an investment decision with respect to the Subscribed Shares, including such information regarding the Transactions and the
business of Semantix and its subsidiaries. In making its decision to purchase the Subscribed Shares, Subscriber represents that it has relied solely upon independent investigation made by Subscriber and the representations, warranties and covenants
of the Issuer and New Pubco contained in this Subscription Agreement. Without limiting the generality of the foregoing, Subscriber has not relied on any statements or other information provided by anyone, other than the representations, warranties,
covenants and agreements of the Issuer and New Pubco expressly set forth in this Subscription Agreement. Subscriber acknowledges and agrees that Subscriber has received access to and has had an adequate opportunity to review such information as
Subscriber deems necessary in order to make an investment decision with respect to the Subscribed Shares, including with respect to the Issuer, New Pubco, Semantix and the Transactions. Subscriber represents and agrees that Subscriber and
Subscriber’s professional advisor(s), if any, have had the full 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 and Semantix. Subscriber represents and warrants it is relying exclusively on its own sources of information, investment analysis and due diligence (including professional advice
you deem appropriate) with respect to the Transactions, the Subscribed Shares and the business, condition (financial and otherwise), management, operations, properties and prospects of the Issuer, New Pubco and Semantix including but not limited to
all business, legal, regulatory, accounting, credit and tax matters.

to the date hereof complied in all material respects with the applicable requirements of the Securities Act and the Exchange Act and the rules and regulations of the Commission promulgated thereunder. None of the SEC Documents filed under the
Exchange Act, contained, when filed or, if amended prior to the date of this Subscription Agreement, as of the date of such amendment with respect to those disclosures that are amended, any untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided that the Issuer makes no such representation or warranty


  
 11 












 
with respect to the registration statement on Form F-4 to be filed by the Issuer with respect to the Transactions or any other information relating to
Semantix or any of its affiliates included in any SEC Document or filed as an exhibit thereto. The Issuer has timely filed each report, statement, schedule, prospectus, and registration statement that the Issuer was required to file with the
Commission since its inception and through the date hereof. There are no material outstanding or unresolved comments in comment letters from the Commission staff with respect to any of the SEC Documents. 

2.3. New Pubco’s Representations, Warranties and Agreements. To induce Subscriber to purchase the Subscribed Shares,
New Pubco hereby represents and warrants to Subscriber and agrees with Subscriber, as of the date hereof and as of the Closing Date, as follows: 

2.3.1. New Pubco has been duly incorporated and is validly existing and in good standing under the laws of the Cayman Islands,
with all requisite power and authority to own, lease and operate its properties and conduct its business as presently conducted and to enter into, deliver and perform its obligations under this Subscription Agreement. 

2.3.2. This Subscription Agreement has been duly authorized, validly executed and delivered by New Pubco and, assuming that
this Subscription Agreement constitutes the valid and binding obligation of the Subscriber, is the valid and binding obligation of New Pubco, and is enforceable against New Pubco in accordance with its terms, except as may be limited or otherwise
affected by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other laws relating to or affecting the rights of creditors generally and (ii) principles of equity, whether considered at law or equity. 

2.3.3. Assuming the accuracy of the Subscriber’s representations in Section 2.1 hereof and the Issuer’s
representations in Section 2.3 hereof, the execution, delivery and performance of this Subscription Agreement by New Pubco will not (i) 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 New Pubco pursuant to the terms of any indenture, mortgage, charge, deed of trust, loan agreement, lease,
license or other agreement or instrument to which New Pubco is a party or by which New Pubco is bound or to which any of the property or assets of New Pubco is subject, which would reasonably be expected to have a material adverse effect on New
Pubco’s ability to perform its obligations pursuant to this Subscription Agreement (a “New Pubco Material Adverse Effect”), (ii) result in any violation of the provisions of the organizational documents of New Pubco or
(iii) result in any violation of any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over New Pubco or any of its properties that would reasonably be
expected to have a New Pubco Material Adverse Effect. 

  
 12 












 2.3.4. Neither New Pubco, nor any person acting on its behalf has conducted
any general solicitation or general advertising, including methods described in section 502(c) of Regulation D under the Securities Act, in connection with the offer or sale of any of the Subscribed Shares and neither New Pubco, nor any person
acting on its behalf has offered any of the Subscribed Shares in a manner involving a public offering under, or in a distribution in violation of, the Securities Act or any state securities laws. 

2.3.5. As of the date of this Subscription Agreement and as of immediately prior to the Transactions, the authorized share
capital of New Pubco consists of 50,000 shares, $1.00 par value each. Except as set forth above and pursuant to the Other Subscription Agreements, the Business Combination Agreement, any other transaction agreement executed or to be executed in
connection therewith or as may occur as a result of the transactions contemplated hereby and thereby, there are no outstanding, and between the date hereof and the Closing, New Pubco will not issue, sell or cause to be outstanding any
(a) shares, equity interests or voting securities of New Pubco, (b) securities of New Pubco convertible into or exchangeable for shares or other equity interests or voting securities of New Pubco, (c) options, warrants or other rights
(including preemptive rights) or agreements, arrangements or commitments of any character, whether or not contingent, of New Pubco to subscribe for, purchase or acquire from any individual, entity or other person, and no obligation of New Pubco to
issue, any ordinary shares of New Pubco, or any other equity interests or voting securities in New Pubco or any securities convertible into or exchangeable or exercisable for such shares or other equity interests or voting securities,
(d) equity equivalents or other similar rights of or with respect to New Pubco, or (e) obligations of New Pubco to repurchase, redeem, or otherwise acquire any of the foregoing securities, shares, options, equity equivalents, interests or
rights. There are no shareholder agreements, voting trusts or other agreements or understandings to which New Pubco is a party or by which it is bound relating to the voting of any securities of New Pubco, other than as contemplated by the Business
Combination Agreement, or any other transaction agreement executed or to be executed in connection therewith or as may occur as a result of the transactions contemplated hereby and thereby. There are no securities or instruments issued by or to
which New Pubco is a party containing anti-dilution or similar provisions that have not been waived or annulled that will be triggered by the issuance of (i) the Subscribed Shares or (ii) the shares to be issued pursuant to any Other
Subscription Agreement that have not been or will not be validly waived on or prior to the closing of the Transactions. 

2.3.6. Except for such matters as would not reasonably be expected to have, individually or in the aggregate, a New Pubco
Material Adverse Effect, as of the date hereof there is no (i) suit, claim, action, or proceeding before any governmental authority or arbitrator pending or, to the knowledge of New Pubco, threatened, or (ii) unsatisfied judgment or any
open injunction of any governmental authority or arbitrator outstanding against New Pubco. 
 2.3.7. New Pubco is in
compliance with all applicable laws, except where such non-compliance would not reasonably be expected to have a New Pubco Material Adverse Effect. As of the date hereof, New Pubco has not received any written
communication from a governmental entity, exchange or self-regulatory organization that alleges that New Pubco 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, individually or in the aggregate, be reasonably expected to have a New Pubco Material Adverse Effect. 

  
 13 












 2.3.8. New Pubco 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 or other person in connection with the execution, delivery
and performance by New Pubco of this Subscription Agreement (including, without limitation, the issuance of the Subscribed Shares), other than (i) filings with the Commission, (ii) filings required by applicable state securities laws,
(iii) filings required in accordance with Section 4, (iv) those required by the Nasdaq, (v) filings required to consummate the Transactions as provided under the Business Combination Agreement, and
(vi) filings, the failure of which to obtain would not be reasonably be expected to have, individually or in the aggregate, a New Pubco Material Adverse Effect. 

2.3.9. No broker, finder or other financial consultant has acted on behalf of New Pubco in connection with this Subscription
Agreement or the transactions contemplated hereby in such a way as to create any liability on Subscriber. 
 3. Settlement Date and
Delivery. 
 3.1. Closing. The closing of the Subscription contemplated hereby (the “Closing”) shall occur on the
date of, and substantially concurrently with, the consummation of the Transactions (the date of the Closing, the “Closing Date”). Upon delivery of 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 (the “Expected Closing Date”), upon satisfaction (or, if
applicable, waiver) of the conditions set forth in this Section 3, Subscriber shall deliver to the Issuer, the Purchase Price for the Subscribed Shares, no later than three (3) Business Days prior to the Expected
Closing Date 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. Prior to or at the Closing,
Subscriber shall deliver to the Issuer, or New Pubco, as the case may be, a duly completed and executed Internal Revenue Service Form W-9 or appropriate Form W-8. If the
Transactions are not consummated within three (3) Business Days after the Expected Closing Date, the Issuer shall promptly (but no later than three (3) Business Days thereafter) return or cause the return of the Purchase Price to
Subscriber by wire transfer of United States dollars in immediately available funds to an account specified by Subscriber, and any book-entries for the Subscribed Shares shall be deemed repurchased and cancelled. Notwithstanding such return,
(i) a failure to close on the Expected Closing Date shall not, by itself, be deemed to be a failure of any of the conditions to Closing set forth in this Section 3 to be satisfied or waived on or prior to the Closing
Date, and (ii) unless and until this Subscription Agreement is terminated in accordance with Section 5 hereof, such return of funds shall not terminate this Subscription Agreement or relieve Subscriber of its
obligation to purchase the Subscribed Shares at the Closing upon delivery by the Issuer of a subsequent Closing Notice and Subscriber shall remain obligated (A) to redeliver funds to the Issuer following the Issuer’s delivery to Subscriber
of a new Closing Notice and (B) to consummate the Closing upon satisfaction of the conditions set forth in this Section 3. For purposes of this Subscription Agreement, “Business Day” means any day
that, in New York, New York, São Paulo, Brazil, and in the Cayman Islands is neither a legal holiday nor a day on which banking institutions are generally authorized or required by law or regulation to close. 

  
 14 












 3.2. Conditions to Closing of the Issuer and New Pubco. 

The Issuer’s obligations to sell and issue the Subscribed Shares at the Closing are subject to the fulfillment or (to the extent
permitted by applicable law) waiver by the Issuer and New Pubco, on or prior to the Closing Date, of each of the following conditions: 

3.2.1. Representations and Warranties Correct. The representations and warranties made by Subscriber in
Section 2.1 hereof shall be true and correct in all material respects when made (other than representations and warranties that are qualified as to materiality or Subscriber Material Adverse Effect, which
representations and warranties shall be true and correct in all respects), and shall be true and correct in all material respects on and as of the Closing Date (unless they specifically speak as of another date in which case they shall be true and
correct in all material respects as of such date) (other than representations and warranties that are qualified as to materiality or Subscriber Material Adverse Effect, which representations and warranties shall be true in all respects) with the
same force and effect as if they had been made on and as of said date, but in each case without giving effect to consummation of the Transactions. 

3.2.2. Compliance with Covenants. Subscriber shall have wired the Purchase Price in accordance with
Section 3.1 of this Subscription Agreement and otherwise have performed, satisfied and complied in all material respects with the covenants, agreements and conditions required by this Subscription Agreement to be performed,
satisfied or complied with by Subscriber at or prior to the Closing. 
 3.2.3. Closing of the Transactions. All
conditions precedent to each of the Issuer’s and Semantix’s obligations to consummate, or cause to be consummated, the Transactions set forth in the Business Combination Agreement shall have been satisfied or waived by the party entitled
to the benefit thereof under the Business Combination Agreement (other than those conditions that (x) may only be satisfied at the consummation of the Transactions (including to the extent that any such condition is dependent upon the
consummation of the purchase and sale of the Subscribed Shares pursuant to this Subscription Agreement and the Other Subscription Agreements), but subject to satisfaction or waiver by such party of such conditions as of the consummation of the
Transactions, or (y) will be satisfied by the Closing and the closing of the transactions contemplated by the Other Subscription Agreements). 

3.2.4. Legality. There shall not be in force any order, judgment, injunction by or with any governmental authority,
statute, rule or regulation enjoining or prohibiting the consummation of the Subscription. 
  

  
 15 












 3.3. Conditions to Closing of Subscriber. 

Subscriber’s obligation to purchase the Subscribed Shares at the Closing is subject to the fulfillment or (to the extent permitted by
applicable law) written waiver by Subscriber, on or prior to the Closing Date, of each of the following conditions: 
 3.3.1.
Representations and Warranties Correct. The representations and warranties made by the Issuer in Section 2.2 and New Pubco in Section 2.3 hereof shall be true and correct in all
material respects when made (other than representations and warranties that are qualified as to materiality or Issuer Material Adverse Effect or New Pubco Material Adverse Effect, as the case may be, which representations and warranties shall be
true and correct in all respects), and shall be true and correct in all material respects on and as of the Closing Date (unless they specifically speak as of another date in which case they shall be true and correct in all material respects as of
such date) (other than representations and warranties that are qualified as to materiality or Issuer Material Adverse Effect or New Pubco Material Adverse Effect, as the case may be, which representations and warranties shall be true and correct in
all respects) with the same force and effect as if they had been made on and as of said date, but in each case without giving effect to consummation of the Transactions. 

3.3.2. Compliance with Covenants. The Issuer and New Pubco shall have performed, satisfied and complied in all material
respects with the covenants, agreements and conditions required by this Subscription Agreement to be performed, satisfied or complied with by the Issuer or New Pubco 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 or New Pubco to consummate the Closing. 

3.3.3. Closing of the Transactions. All conditions precedent to the consummation of the Transactions set forth in the
Business Combination Agreement shall have been satisfied or waived by the party entitled to the benefit thereof under the Business Combination Agreement (other than those conditions that (x) may only be satisfied at the consummation of the
Transactions (including to the extent that any such condition is dependent upon the consummation of the purchase and sale of the Subscribed Shares pursuant to this Subscription Agreement and the Other Subscription Agreements), but subject to
satisfaction or waiver by such party of such conditions as of the consummation of the Transactions, or (y) will be satisfied by the Closing and the closing of the transactions contemplated by the Other Subscription Agreements). 

3.3.4. Legality. There shall not be in force any order, judgment, injunction, decree, writ, stipulation, determination
or award, in each case, entered by or with any governmental authority, statute, rule or regulation enjoining or prohibiting consummation of the transactions contemplated by this Subscription Agreement or the Transactions 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 result in an Issuer Material Adverse Effect or New Pubco Material Adverse Effect, as the case may be). 

  
 16 












 3.3.5. Listing. No suspension of the qualification of the Ordinary
Shares for offering or sale or trading on the Nasdaq shall have occurred, and the Subscribed Shares shall be approved for listing on the Nasdaq, subject to official notice of issuance. 

4. Registration Statement. 

4.1. New Pubco will use its commercially reasonable efforts to, within thirty (30) calendar days after the consummation of
the Transactions (the “Filing Date”), submit or file with the Commission a registration statement (the “Registration Statement”) registering the resale of the Subscribed Shares acquired by Subscriber pursuant to
this Subscription Agreement which are eligible for registration (determined as of two (2) Business Days prior to such submission or filing) (the “Registrable Securities”), and New Pubco shall use its commercially reasonable
efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) the 60th calendar day (or 90th calendar day if the Commission notifies New Pubco that it will
“review” the Registration Statement) following the Filing Date and (ii) the 10th Business Day after the date New Pubco is notified (orally or in writing, whichever is earlier) by the Commission that the Registration Statement will not
be “reviewed” or will not be subject to further review (such earlier date, the “Effectiveness Date”); provided, however, that if such day falls on a Saturday, Sunday or other day that the Commission is closed for business,
the Effectiveness Date shall be extended to the next Business Day on which the Commission is open for business; provided, further, that New Pubco’s obligations to include the Registrable Securities in the Registration Statement are contingent
upon Subscriber furnishing in writing to New Pubco such information as shall be reasonably requested by New Pubco to effect the registration of the Registrable Securities, including a completed and executed selling shareholders questionnaire in
customary form to New Pubco that contains the information required by Commission rules for a Registration Statement regarding Subscriber, the securities of the New Pubco held by Subscriber and the intended method of disposition of the Registrable
Securities (which shall be limited to non-underwritten public offerings) to effect the registration of the Registrable Securities, and Subscriber shall execute such documents in connection with such
registration as New Pubco may reasonably request that are customary of a selling stockholder in similar situations, including providing that New Pubco shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement,
if applicable, during any customary blackout or similar period or as permitted hereunder; provided, that 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 Registrable Securities. For purposes of clarification, any failure by New Pubco to file the Registration Statement by the Filing Date or to effect such
Registration Statement by the Effectiveness Date shall not otherwise relieve New Pubco of its obligations to file or effect the Registration Statement as set forth above in this Section 4. For purposes of this
Section 4, Registrable Securities shall include, as of any date of determination, the Subscribed Shares and any other equity security of New Pubco issued or issuable with respect to the Subscribed Shares by way of
share split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event or otherwise. In no event shall Subscriber be identified as a statutory underwriter in the Registration Statement unless requested by the
Commission. Notwithstanding the foregoing, if the Commission prevents New Pubco from including any or all of the Subscribed Shares proposed to be registered for resale under the 

  
 17 












 
Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the Subscribed Shares by the applicable shareholders or otherwise, (i) such
Registration Statement shall register for resale such number of Subscribed Shares which is equal to the maximum number of Subscribed Shares as is permitted by the Commission and (ii) the number of Subscribed Shares to be registered for each
selling shareholder named in the Registration Statement shall be reduced pro rata among all such selling shareholders; and as promptly as practicable after being permitted to register additional Subscribed Shares under Rule 415 under the Securities
Act, New Pubco shall amend the Registration Statement or file a new Registration Statement to register such Subscribed Shares not included in the initial Registration Statement and shall use commercially reasonable efforts to have such amendment or
Registration Statement to become effective as promptly as practicable. 
 4.2. At its expense New Pubco shall: 

4.2.1. except for such times as New Pubco 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 New Pubco 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 New Pubco to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable), and (iii) two (2) years from the date of effectiveness of the Registration
Statement. The period of time during which New Pubco is required hereunder to keep a Registration Statement effective is referred to herein as the “Registration Period”; 

4.2.2. during the Registration Period, use its best efforts to advise Subscriber as promptly as practicable: 

(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 New Pubco 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 

  
 18 












 (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, New Pubco shall not, when so advising Subscriber of such events described in
Section 4.2.2 above, provide Subscriber with any material, nonpublic information regarding New Pubco other than to the extent that providing notice to Subscriber of the occurrence of the events listed in (a) through
(d) above constitutes material, nonpublic information regarding New Pubco; 
 4.2.3. during the Registration Period, 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. during the Registration Period, upon the occurrence of any event contemplated in
Section 4.2.2(d), except for such times as New Pubco is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, New Pubco shall use its commercially
reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to 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. during the Registration Period, use its commercially reasonable efforts to cause all
Subscribed Shares to be listed on each securities exchange or market, if any, on which New Pubco’s ordinary shares are then listed. 

4.3. Notwithstanding anything to the contrary in this Subscription Agreement, New Pubco 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 (i) as New Pubco may determine to be necessary in connection with
(a) the preparation and filing of a post-effective amendment to the Registration Statement following the filing of New Pubco’s Annual Report on Form 20-F or (b) 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, or (ii) if the filing, effectiveness or continued use of any Registration
Statement would require New Pubco to make any public disclosure of material non-public information, which disclosure, in the good faith determination of the board of directors of New Pubco, after consultation
with counsel to New Pubco (a) would not be required to be made at such time if the Registration Statement were not being filed, (b) New Pubco has a bona fide business purpose for not making such information public, or (c) would be
seriously detrimental to New Pubco and the majority of New Pubco’s board of directors conclude as a result that it is essential to defer such filing or (iii) if such delay or suspension arises out of, or is a result of, or is related to
any statement or communication that 

  
 19 












 
relates to changes to historical accounting policies of New Pubco in connection with any order, directive, guideline, comment or recommendation from the Commission that is applicable to
New Pubco or other accounting matters, or any related disclosure or other matters (each such circumstance, a “Suspension Event”); provided, however, that New Pubco may not delay or suspend the Registration Statement on
more than three (3) occasions or for more than ninety (90) consecutive calendar days, or more than one hundred twenty (120) total calendar days, in each case during any twelve-month period. Upon receipt of any written notice from New
Pubco 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
(i) it will immediately discontinue offers and sales of the Registrable Securities 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 New Pubco 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 New
Pubco 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 New Pubco except as required by law. If so directed by New Pubco, Subscriber will
deliver to New Pubco or, in Subscriber’s sole discretion destroy, all copies of the prospectus covering the Registrable Securities 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. 
 4.4. Subscriber may deliver written notice (including via email in accordance
with Section 6.2) (an “Opt-Out Notice”) to New Pubco requesting that Subscriber not receive notices from New Pubco otherwise required
by Section 4.3; provided, however, that Subscriber may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from Subscriber (unless subsequently revoked), (i) New Pubco shall not deliver any such notices to Subscriber and Subscriber shall no longer be entitled to the rights associated with
any such notice and (ii) each time prior to Subscriber’s intended use of an effective Registration Statement, Subscriber will notify New Pubco in writing at least two (2) business days in advance of such intended use, and if a notice
of a Suspension Event was previously delivered (or would have been delivered but for the provisions of this Section 4.4) and the related suspension period remains in effect, New Pubco will so notify Subscriber, within
two (2) business days of Subscriber’s notification to New Pubco, by delivering to Subscriber a copy of such previous notice of Suspension Event, and thereafter will provide Subscriber with the related notice of the conclusion of such
Suspension Event immediately upon its availability.

 4.5. The parties agree that: 

4.5.1. New Pubco shall indemnify and hold harmless, to the extent permitted by law, Subscriber (to the extent a seller under
the Registration Statement), its officers, directors, agents, partners, members, managers, shareholders, and investment advisers and each person who controls such Subscriber (within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act), from and against any and all losses, claims, damages, liabilities and reasonable and documented out-of-pocket costs and expenses
(including, without limitation, any reasonable and documented outside attorneys’ fees of one (1) law firm) (collectively, “Losses”), that arise out of or are based upon any untrue or alleged untrue statement of material
fact contained in any Registration Statement (or incorporated by reference therein), prospectus included in any Registration Statement or preliminary prospectus or any amendment thereof or supplement thereto 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, except insofar as the same are caused by or contained in any information furnished in writing to New Pubco by or on behalf of Subscriber expressly for use therein or Subscriber has omitted a material fact from such
information; provided, however, that the indemnification contained in this Section 4.5 shall not apply to amounts paid in settlement of any Losses if such settlement is effected without the consent of New Pubco
(which consent shall not be unreasonably withheld, conditioned or delayed), nor shall New Pubco 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 Subscriber, (B) in connection with any failure of such person to deliver or cause to be delivered a prospectus made available by New Pubco in a timely manner, (C) as a result of offers or sales effected by
or on behalf of any person by means of a “free writing prospectus” (as defined in Rule 405 under the Securities Act) that was not authorized in writing by New Pubco, or (D) in connection with any offers or sales effected by or on
behalf of Subscriber in violation of Section 4.3 hereof. New Pubco 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 4 of which New Pubco is aware. 
 4.5.2. In connection with any
Registration Statement in which the Subscriber is participating, the Subscriber shall furnish (or cause to be furnished) to New Pubco in writing such information as New Pubco reasonably requests for use in connection with any such Registration
Statement or prospectus, and Subscriber agrees, severally and not jointly with any person that is a party to the Other Subscription Agreements, to indemnify and hold harmless, to the extent permitted by law, New Pubco, its directors, officers,
agents, partners, members, managers, shareholders, and advisers and agents and each person who controls New Pubco (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act) against any and all Losses that
arise out of or are based upon any untrue or alleged untrue statement of material fact contained in any Registration Statement, prospectus included in any Registration Statement or preliminary prospectus or any amendment thereof or supplement
thereto or arising out of or relating to any omission of 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, but only to the extent that such untrue statement or omission is contained in (or not contained in, in the case of an omission) any information or affidavit


  
 21 












 
so furnished in writing by or on behalf of such Subscriber expressly for use therein; provided, however, that the indemnification contained in this
Section 4.5 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).
Notwithstanding anything to the contrary herein, in no event shall the liability of Subscriber be greater in amount than the dollar amount of the net proceeds received by Subscriber upon the sale of the Subscribed Shares purchased pursuant to this
Subscription Agreement giving rise to such indemnification obligation. 
 4.5.3. Any person entitled to indemnification
herein shall (1) 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 right to indemnification
hereunder to the extent such failure has not prejudiced the indemnifying party) and (2) 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
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 legal
counsel to any indemnified party a conflict of interest exists 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 (which
consent shall not be unreasonably withheld, conditioned or delayed), 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) or which settlement includes a statement or admission of fault and culpability on the part of such indemnified party or which does not 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. 

4.5.4. The indemnification provided for under this Subscription Agreement shall remain in full force and effect regardless of
any investigation made by or on behalf of the indemnified party and shall survive the transfer of the Subscribed Shares purchased pursuant to this Subscription Agreement. 

4.5.5. If the indemnification provided under this Section 4.5 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. The relative fault of the
indemnifying party and indemnified party shall be determined by reference to, 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 

  
 22 












 
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 or other liabilities referred to above shall be deemed to
include, subject to the limitations set forth in Sections 4.5.1, 4.5.2 and 4.5.3 above, 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 4.5 from any person who was not guilty of such fraudulent
misrepresentation. In no event shall the liability of Subscriber be greater in amount than the dollar amount of the net proceeds received by Subscriber upon the sale of the Registrable Securities giving rise to such contribution obligation. 

5. 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 earliest to occur of (i) such date and time as the Business Combination Agreement is validly terminated in
accordance with its terms, (ii) upon the mutual written agreement of each of the parties hereto to terminate this Subscription Agreement and (iii) nine months from the date hereof if the Closing has not occurred; 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 notify Subscriber of the termination of the Business Combination Agreement reasonably promptly after the termination of such agreement. 

6. Miscellaneous. 
 6.1.
Further Assurances. At the Closing, the parties hereto shall execute and deliver such additional documents to the extent contemplated by this Subscription Agreement and take such additional actions as the parties reasonably may deem to be
practical and necessary in order to consummate the Subscription as contemplated by this Subscription Agreement. 
 6.1.1.
Subscriber acknowledges that the Issuer and New Pubco 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 New Pubco if any of the acknowledgments, understandings, agreements, representations and warranties made by Subscriber set forth herein are no longer accurate in all material respects. The Issuer and New Pubco
acknowledge that Subscriber will rely on the acknowledgments, understandings, agreements, representations and warranties made by the Issuer and New Pubco contained in this Subscription Agreement. The Subscriber acknowledges and agrees that the
purchase by the Subscriber of Subscribed Shares will constitute a reaffirmation of the acknowledgments, understandings, agreements, representations and warranties herein by Subscriber as of the time of such purchase. 

  
 23 












 6.1.2. Each of the Issuer, New Pubco and the Subscriber 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 or New Pubco may request from Subscriber such additional information as the Issuer or New Pubco may
reasonably deem necessary to evaluate the eligibility of Subscriber to acquire the Subscribed Shares and in connection with the inclusion of the Shares in the Registration Statement, and Subscriber shall provide such information as may be reasonably
requested, to the extent within Subscriber’s possession and control or otherwise readily available to Subscriber, provided that the Issuer and New Pubco agree to keep confidential any such information provided by Subscriber, except as may be
required by applicable law, rule, regulation or in connection with any legal proceeding or regulatory request. Subscriber acknowledges that Issuer and New Pubco may file a copy of this Subscription Agreement with the SEC as an exhibit to a current
or periodic report or a registration statement of Issuer and New Pubco. 
 6.1.4. Each of Subscriber, the Issuer and New
Pubco shall pay all of its own respective expenses in connection with this Subscription Agreement and the transactions contemplated herein (it being agreed that all expenses related to the Registration Statement are for the account of New Pubco to
the extent provided in Section 4). 
 6.1.5. Each of Subscriber, the Issuer and New Pubco 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 described therein prior to the consummation of the
Transactions. 
 6.1.6. Until the Closing or the earlier termination of this Agreement, neither the Issuer nor the New Pubco
shall enter into Other Subscription Agreements that have the effect of establishing rights or otherwise benefitting Other Subscribers in a manner more favorable in any material respect to such Other Subscribers than the rights and benefits
established in favor of the Subscriber as set forth herein, unless, in any such case, the Subscriber has been offered such rights and benefits. 

6.2. Notices. Any notice or communication required or permitted hereunder shall be in writing and either delivered personally, emailed
or sent by overnight mail via a reputable overnight carrier, or sent by certified or registered mail, postage prepaid, and shall be deemed to be given and received (i) when so delivered personally, (ii) when sent, with no mail
undeliverable or other rejection notice, if sent by email, or (iii) three (3) Business Days after the date of mailing to the address below or to such other address or addresses as such person may hereafter designate by notice given hereunder,
provided that such mail must be sent by FedEx or other internationally recognized overnight delivery service:

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 and Amendments. This Subscription Agreement may not be amended, modified, supplemented or waived except by an
instrument in writing, signed by the party against whom enforcement of such amendment, modification, supplement or waiver is sought (and, and in those cases where the New Pubco’s consent is required, also signed by Semantix). 

  
 26 












 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 Subscribed Shares) may be transferred or assigned without the prior written consent of the Issuer and New Pubco; provided that Subscriber’s
rights and obligations hereunder may be assigned to (i) any affiliate or manager, as applicable of the Subscriber or (i) one or more funds or accounts managed by the same investment manager as Subscriber, without the prior consent of the
Issuer and New Pubco, provided that such assignee(s) agrees in writing to be bound by the terms hereof, and upon such assignment by a Subscriber, the assignee(s) shall become Subscriber hereunder and have the rights and obligations and be deemed to
make the representations and warranties of Subscriber provided for herein to the extent of such assignment; provided further that, no assignment shall relieve the assigning party of any of its obligations hereunder, including any
assignment to any fund or account managed by the same investment manager as Subscriber. 
 6.6. Benefit. 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. This Subscription Agreement shall not
confer rights or remedies upon any person other than the parties hereto and their respective successors and assigns. 
 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 laws of the State of Delaware, without giving effect to the principles of conflicts of law thereof. 

6.8. Arbitration. (a) Any disputes arising out or related to this Agreement, including the existence,
validity, interpretation, or performance of this Agreement or the transactions contemplated by this Agreement, shall be settled as far as possible by negotiations between the parties. If the parties cannot agree on an amicable settlement within
thirty (30) days from written notice of a dispute by one party to the other party, any disputes shall be submitted for decision and final resolution to arbitration, under the Rules of Arbitration of the International Chamber of Commerce then in
effect (the “Rules”). 
 (b) The arbitration tribunal shall be composed of three (3) neutral and impartial arbitrators, appointed pursuant to
the Rules. The claimant shall appoint one arbitrator, the respondent shall appoint one arbitrator, and the two party-appointed arbitrators shall choose a third arbitrator within thirty (30) days of the appointment of the respondent’s
arbitrator, who shall serve as president of the tribunal thus composed. If the parties fail to appoint an arbitrator within the time periods provided in the Rules, or if the two party-appointed arbitrators fail to appoint a third arbitrator
within the thirty (30)-day period provided above, then the arbitrator(s) shall be appointed by the Court of Arbitration of the International Chamber of Commerce upon the request of the arbitrators and/or
either of the parties. 

  
 27 












 (c) The seat of arbitration shall be New York City, unless the parties otherwise agree in
writing. The official arbitration language shall be English. Each of the parties agrees that notice as provided in Section 6.2 of this Agreement shall constitute sufficient service of process and the parties further
waive any argument that such service is insufficient. 
 (d) The arbitration decision shall be final and binding upon both parties and the
parties agree that any award granted pursuant to such decision may be entered forthwith in any court of competent jurisdiction.
 (e) The
costs of the arbitration, including fees of the arbitrators, shall be borne equally by the parties, but the arbitral tribunal shall be empowered to include in its award a determination regarding the allocation of the costs of the arbitration,
including any legal fees, among the parties. 
 (f) The arbitration and all information and materials obtained or produced in the arbitration
shall be confidential. 
 (g) Nothing in this Section shall prevent a party from seeking provisional, interim, or conservatory measures from
any court of competent jurisdiction prior to the appointment of the arbitral tribunal if any such party believes in good faith that it will suffer irreparable injury. Any such request by a party to a court for provisional, interim, or conservatory
measures shall not be deemed incompatible with the agreement to arbitrate or a waiver of the right to arbitrate. Without prejudice to such provisional, interim, or conservatory measures as may be available from any court, the arbitral tribunal shall
have full authority to grant provisional, interim, and conservatory remedies and to direct the parties to request that any court modify or vacate any temporary or preliminary relief issued by such court, and to award damages for the failure of any
party to respect the arbitral tribunal’s orders to that effect. 
 6.9. [Intentionally Omitted.] 

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

6.11. 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. 

  
 28 












 6.12. Remedies. 

6.12.1. The parties agree that irreparable damage would occur if this Subscription Agreement is not performed or the Closing is
not consummated in accordance with its specific terms or is 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 parties hereto 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 parties hereto to cause the other 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. 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 6.12 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. 
 6.12.2. The parties acknowledge and agree that this Section 6.12 is an integral
part of the transactions contemplated hereby and without that right, the parties hereto would not have entered into this Subscription Agreement. 

6.13. Survival of Representations and Warranties and Covenants. All representations and warranties made by the parties hereto, and all
covenants and other agreements of the parties hereto, in this Subscription Agreement shall survive the Closing until the expiration of any statute of limitations pursuant to applicable law or in accordance with their respective terms, if a shorter
period. 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. 
 6.14. 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. 

6.15. 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 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. 

  
 29 












 6.16. 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. 
 6.17. 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. 

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 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 or New Pubco or their respective officers, directors, employees or agents have provided to Subscriber
prior to the filing of the Disclosure Document in connection with the investment contemplated by this Agreement. Upon the issuance of the Disclosure Document, to the actual knowledge of the Issuer and New Pubco, Subscriber shall not be in possession
of any material, non-public information received from the Issuer, New Pubco or any of their respective officers, directors, employees or agents in connection with the investment contemplated by this Agreement,
and Subscriber shall no longer be subject to any confidentiality or similar obligations under any current agreement, whether written or oral, with the Issuer or New Pubco, relating to the transactions contemplated by this Subscription Agreement.

 7.2. The Issuer and the New Pubco shall not (and shall cause their respective officers, directors, employees and agents not to) publicly
disclose the name of Subscriber or any affiliate or investment adviser of Subscriber, or include the name of Subscriber or any affiliate or investment adviser of Subscriber without the prior written consent (including by e-mail) of Subscriber (i) in any press release or marketing materials, or (ii) in any filing with the Commission or any regulatory agency or trading market, which approval shall not be


  
 30 












 
unreasonably withheld or conditioned; provided that no consent pursuant to this Section 7.2 shall be required to the extent any proposed release or statement is
substantially equivalent to the information that has previously been made public without breach of the obligation under this Section 7.2. The restriction in this Section 7.2 shall not apply to the
extent the disclosure is 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
regulations of Nasdaq, in which case the Issuer or New Pubco, as applicable, shall provide Subscriber with prior written notice (including by e-mail) of such permitted disclosure, and shall reasonably consult
with Subscriber regarding such disclosure. 
 8. Trust Account Waiver. In addition to the waiver of Semantix pursuant to
Section 7.7 of the Business Combination Agreement, and notwithstanding anything to the contrary set forth herein, each of the Issuer and 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”). Each of the Issuer and 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 past, present or future 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, but not limited to, any redemption right with respect to any such securities of the Issuer, except to the
extent that Subscriber has otherwise agreed in writing with the Issuer not to exercise such redemption right. 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. 

9. Non-Reliance. Subscriber acknowledges that it is not relying upon, and has not relied upon,
any statement, representation or warranty made by any person, firm or corporation, other than the representations and warranties of the Issuer and New Pubco expressly set forth in this Subscription Agreement, in making its investment or decision to
invest in the Subscribed Shares. Subscriber agrees that none of (i) any Other Subscriber pursuant to this Subscription Agreement or any other agreement related to the private placement of shares of the Issuer’s capital stock (including the
controlling persons, officers, directors, partners, agents or employees of any such Other Subscriber), (ii) any party to the Business Combination Agreement (other than the Issuer or New Pubco), or (iii) any affiliates, or any control persons,
officers, directors, employees, partners, agents or representatives of any of the Issuer, New Pubco or any other party to the Business Combination Agreement shall be liable (including without limitation, for or with respect to any losses, claims,
damages, obligations, penalties, judgments, awards, liabilities, costs, expenses or disbursements incurred by the Subscriber or any other person or entity), 

  
 31 












 
whether in contract, tort or otherwise, or have any liability or obligation, to Subscriber or any person claiming through Subscriber, related to the private placement of the Subscribed Shares,
the negotiation hereof or the subject matter hereof, or the transactions contemplated hereby, for any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase of the Subscribed Shares. Nothing
contained herein or in any Other Subscription Agreement, and no action taken by the Subscriber or any Other Subscriber pursuant hereto or thereto, shall be deemed to constitute the Subscriber and Other Subscribers as a partnership, an association, a
joint venture or any other kind of entity, or create a presumption that the Subscriber and Other Subscriber s are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated hereby. 

10. Restrictive Legend. If the Subscribed Shares are eligible to be sold without restriction under, and without the New Pubco being in
compliance with the current public information requirements of, Rule 144 under the Securities Act, then at Subscriber’s request in connection with the sale of such Subscribed Shares, and subject to Subscriber’s execution of customary
representation letters, New Pubco will (A) provide all documentation and instruction required for the transfer agent for the Subscribed Shares (the “Transfer Agent”) and (B) reasonably cooperate with the Transfer Agent
(including, if required by the Transfer Agent, delivering an opinion of New Pubco’s counsel in a form reasonably acceptable to the Transfer Agent) to remove any remaining restrictive legend set forth on such Subscribed Shares that are the
subject of the Subscriber’s request; provided that, notwithstanding the foregoing, New Pubco 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. 
 11. Massachusetts Business
Trust. If Subscriber is a Massachusetts Business Trust, a copy of the Agreement and Declaration of Trust of Subscriber or any affiliate thereof is on file with the Secretary of State of the Commonwealth of Massachusetts and notice is hereby
given that the Subscription Agreement is executed on behalf of the trustees of Subscriber or any affiliate thereof as trustees and not individually and that the obligations of the Subscription Agreement are not binding on any of the trustees,
officers or stockholders of Subscriber or any affiliate thereof individually but are binding only upon Subscriber or any affiliate thereof and its assets and property.
