Such Shelf shall provide for the resale of the Registrable Securities included therein pursuant to any method or combination of methods legally available to, and requested by, the majority-in-interest of the Holders named therein. The Company shall maintain a Shelf in accordance with the terms hereof, and shall prepare and file with the SEC such amendments, including post-effective amendments, and supplements as may be necessary to keep a Shelf continuously effective, available for use to permit the Holders named therein to sell their Registrable Securities included therein and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities outstanding. In the event the Company files a Form F-1 Shelf, the Company shall use its commercially reasonable efforts to convert the Form F-1 Shelf (and any Subsequent Shelf Registration Statement) to a Form F-3 Shelf as soon as reasonably practicable after the Company is eligible to use Form F-3. The Company’s obligation under this Section 2.1, shall be subject to Section 3.5.

If any Shelf ceases to be effective under the Securities Act for any reason at any time while Registrable Securities are still outstanding, the Company shall use its commercially reasonable efforts to as promptly as is reasonably practicable cause such Shelf to again become effective under the Securities Act (including using its commercially reasonable efforts to obtain the prompt withdrawal of any order suspending the effectiveness of such Shelf), and shall use its commercially reasonable efforts to, as promptly as is reasonably practicable, amend such Shelf in a manner reasonably expected to result in the withdrawal of any order suspending the effectiveness of such Shelf or file an additional Registration Statement as a Shelf Registration (a “Subsequent Shelf Registration Statement”) registering the resale of all Registrable Securities (determined as of two (2) Business Days prior to such filing), and pursuant to any method or combination of methods legally available to, and requested by, a majority-in-interest of the Holders named therein. If a Subsequent Shelf Registration Statement is filed, the Company shall use its commercially reasonable efforts to (i) cause such Subsequent Shelf Registration Statement to become effective under the Securities Act as promptly as is reasonably practicable after the filing thereof and (ii) keep such Subsequent Shelf Registration Statement continuously effective, available for use to permit the Holders named therein to sell their Registrable Securities included therein and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities outstanding.

Otherwise, such Subsequent Shelf Registration Statement shall be on another appropriate form. The Company’s obligation under this Section 2.2, shall be subject to Section 3.5.

2.3 Request for Underwritten Offering.

2.3.1 Shelf Underwriting. Subject to Section 3.5.1, when an effective Shelf is on file with the SEC, any Demanding Holder may from time to time, following the expiration of any applicable Lock-Up Period, request in writing to sell all or any part of its Registrable Securities pursuant to an Underwritten Offering pursuant to the Registration Statement, which written request shall describe the number and type of securities to be included in such Registration and the intended method(s) of distribution thereof; provided that the Company shall only be obligated to effect an Underwritten Offering if such offering shall include Registrable Securities proposed to be sold by the Demanding Holder, either individually or together with other Demanding Holders, with a total offering price reasonably expected to exceed, in the aggregate, $75 million (the “Minimum Takedown Threshold”), net of all underwriting discounts and commissions. The Demanding Holder shall make such election by delivering to the Company a written request (an “Underwriting Request”) for such Underwritten Offering specifying the number of its Registrable Securities that the Demanding Holder desires to sell pursuant to such Underwritten Offering (the “Shelf Underwriting”). The Demanding Holder, after consultation with the Company, shall have the right to select the Underwriters for such offering (which shall consist of one or more reputable internationally recognized investment banks). The Demanding Holders may demand an aggregate of not more than eight (8) Shelf Underwritings pursuant to this Agreement (of which the Sponsor may demand not more than four (4)), and the Company is not obligated to effect (x) more than four (4) Shelf Underwritings in any twelve (12) month period (provided, that, the Sponsor may demand not more than two (2) Shelf Underwritings per year) or (y) a Shelf Underwriting within sixty (60) days after the closing of a prior Shelf Underwriting. The Company shall use its reasonable best efforts to effect such Shelf Underwriting, including the filing of any Prospectus supplement or any post-effective amendments and otherwise taking any action necessary to include therein all disclosure and language deemed necessary or advisable by the Demanding Holder to effect such Shelf Underwriting.

2.3.2 Reduction of Shelf Underwriting. If the managing Underwriter or Underwriters in a Shelf Underwriting, in good faith, advises the Company, the Demanding Holders and, if any, the Holders requesting piggyback rights pursuant to this Agreement with respect to such Shelf Underwriting (the “Requesting Holders”) in writing that the dollar amount or number of Registrable Securities that the Demanding Holders and the Requesting Holders (if any) desire to sell, taken together with all other Class A Ordinary Shares or other equity securities that the Company desires to sell and all other Class A Ordinary Shares or other equity securities, if any, that have been requested to be sold in the

Shelf Underwriting pursuant to separate written contractual piggy-back registration rights held by any other Holder, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Shelf Underwriting without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”), then the Company shall include in the Shelf Underwriting, before including any Class A Ordinary Shares or other equity securities proposed to be sold by the Company or by other holders of Class A Ordinary Shares or other equity securities, the Registrable Securities of (i) first, the Demanding Holders that can be sold without exceeding the Maximum Number of Securities (pro rata based on the respective number of Registrable Securities that each Demanding Holder has requested be included in such Shelf Underwriting and the aggregate number of Registrable Securities that all of the Demanding Holders have requested be included in such Shelf Underwriting), (ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), the Requesting Holders (if any) (pro rata based on the respective number of Registrable Securities that each Requesting Holder (if any) has requested be included in such Shelf Underwriting and the aggregate number of Registrable Securities that all of the Requesting Holders have requested be included in such Shelf Underwriting) that can be sold without exceeding the Maximum Number of Securities and (iii) third, to the extent the Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii), any other equity securities requested to be sold in the Shelf Underwriting (pro rata based on the respective number of equity securities requested to be included in such Shelf Underwriting).

2.3.3 Withdrawal. Prior to the filing of the applicable “red xxxxxxx” Prospectus or Prospectus supplement used for marketing the Shelf Underwriting, the majority-in-interest of the Demanding Holders shall have the right to withdraw from the Shelf Underwriting for any or no reason whatsoever upon written notification (a “Withdrawal Notice”) to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from the Shelf Underwriting; provided that the Sponsor or Ambipar Parent may elect to have the Company continue a Shelf Underwriting if the Minimum Takedown Threshold would still be satisfied by the Registrable Securities proposed to be sold in the Shelf Underwriting by such Holders or any of their respective Permitted Transferees, as applicable. If withdrawn, the demand for the Shelf Underwriting shall constitute a demand for the Shelf Underwriting by the Demanding Holder for purposes of Section 2.3.1, unless the Demanding Holder reimburses the Company for all Registration Expenses with respect to the Shelf Underwriting (or, if there are any other Holders participating in the Shelf Underwriting, a pro rata portion of such Registration Expenses based on the respective number of Registrable Securities that the Demanding Holder has requested be included in the Shelf Underwriting); provided that, if the Sponsor or Ambipar Parent elects to continue a Shelf Underwriting pursuant to the proviso in the immediately preceding sentence, such Shelf Underwriting shall instead count as a Shelf Underwriting demanded by the Sponsor or Ambipar Parent, as applicable, for purposes of Section 2.3.1. Following the receipt of any Withdrawal Notice, the Company shall promptly forward such Withdrawal Notice to any other Holders that had elected to participate in such Shelf Underwriting. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with the Shelf Underwriting prior to its withdrawal under this Section 2.3.3.

2.3.4 Piggyback Rights. If any Demanding Holder proposes to conduct a Shelf Underwriting pursuant to Section 2.3.1 then the Company shall give written notice of such proposed offering to all of the Holders of Registrable Securities as soon as practicable but not less than five (5) days before the applicable “red xxxxxxx” prospectus or prospectus supplement used for marketing such Underwritten Offering, which notice shall (a) describe the number and type of securities to be included in such Underwritten Offering, the intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters in such offering, and (b) offer to all of the Holders of Registrable Securities the opportunity to include in such offering such number of Registrable Securities as such Holders may request in writing within five (5) days after receipt of such written notice (such registered offering, a “Piggyback Registration”). Subject to Section 2.3.2, the Company shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and, if applicable, shall use its commercially reasonable efforts to cause the managing Underwriter or Underwriters of such Piggyback Registration to permit the Registrable Securities requested by the Holders pursuant to this Section 2.3.4 to be included therein on the same terms and conditions as any similar securities of the Company included in such registered offering and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. The inclusion of any Holder’s Registrable Securities in a Piggyback Registration shall be subject to such Holder’s agreement to enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Shelf Underwriting. For avoidance of doubt, this Section 2.3.4 shall not apply to a Block Trade or Other Coordinated Offering.

2.3.5 Market Stand-off. In connection with any Underwritten Offering of equity securities of the Company, if requested by the managing Underwriters, each Holder that is (a) an executive officer, (b) a director or (c) a Holder in excess of five percent (5%) of the outstanding Ordinary Shares (and for which it is customary for such a Holder to agree to a lock-up) agrees that it shall not Transfer any Class A Ordinary Shares or other equity securities of the Company (other than those included in such offering pursuant to this Agreement), without the prior written consent of the Underwriters, during the ninety (90)-day period (or such shorter time agreed to by the managing Underwriters) beginning on the date of pricing of such offering, except as expressly permitted by such lock-up agreement or in the event the managing Underwriters otherwise agree by written consent. Each such Holder agrees to execute a customary lock-up agreement in favor of the Underwriters to such effect (in each case on substantially the same terms and conditions as all such Holders).

2.4 Block Trades; Other Coordinated Offerings.

2.4.1 Notwithstanding any other provision of this Section 2, but subject to Section 3.4, at any time and from time to time when an applicable Lock-Up Period is not in effect and when an effective Shelf is on file with the SEC, if any Demanding Holder wishes to engage in (i) an underwritten registered offering not involving a “roadshow,” an offer commonly known as a “block trade” (a “Block Trade”), or (ii) an “at the market” or similar registered offering through a broker, sales agent or distribution agent, whether as agent or principal (an “Other Coordinated Offering”), in each case, (x) with a total offering price, either individually or together with other Demanding Holders, reasonably expected to exceed $50 million in the aggregate or (y) with respect to all remaining Registrable Securities held by the Demanding Holder, then such Demanding Holder only needs to notify the Company of the Block Trade or Other Coordinated Offering at least ten (10) business days prior to the day such offering is to commence and the Company shall use its commercially reasonable efforts to facilitate such Block Trade or Other Coordinated Offering; provided that the Demanding Holders representing a majority-in-interest of the Registrable Securities wishing to engage in the Block Trade or Other Coordinated Offering shall use commercially reasonable efforts to work with the Company and any Underwriters, brokers, sales agents or placement agents prior to making such request in order to facilitate preparation of the registration statement, prospectus and other offering documentation related to the Block Trade or Other Coordinated Offering.

2.4.2 Prior to the filing of the applicable “red xxxxxxx” prospectus or prospectus supplement used in connection with a Block Trade or Other Coordinated Offering, a majority-in-interest of the Demanding Holders initiating such Block Trade or Other Coordinated Offering shall have the right to submit a Withdrawal Notice to the Company, the Underwriter or Underwriters (if any) and any brokers, sales agents or placement agents (if any) of their intention to withdraw from such Block Trade or Other Coordinated Offering. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a Block Trade or Other Coordinated Offering prior to its withdrawal under this Section 2.4.2.

2.4.3 Notwithstanding anything to the contrary in this Agreement, Section 2.3.4 shall not apply to a Block Trade or Other Coordinated Offering initiated by a Demanding Holder pursuant to this Agreement.

2.4.4 The Demanding Holder in a Block Trade, or Other Coordinated Offering or Demanding Holders representing a majority-in-interest of the Registrable Securities wishing to engage in the Block Trade or Other Coordinated Offering, shall have the right to select the Underwriters and any brokers, sales agents or placement agents (if any) for such Block Trade or Other Coordinated Offering (in each case, which shall consist of one or more reputable nationally recognized investment banks).

2.4.5 A Demanding Holder in the aggregate may demand no more than four (4) Block Trades or Other Coordinated Offerings pursuant to this Section 2.4 in any twelve (12) month period. For the avoidance of doubt, any Block Trade or Other Coordinated Offering effected pursuant to this Section 2.4 shall not be counted as a demand for a Shelf Underwriting pursuant to Section 2.3.1 hereof.

3. Company Procedures

3.1 General Procedures. In connection with any Shelf and/or Underwritten Offering, the Company shall use its commercially reasonable efforts to effect such Registration to permit the sale of such Registrable Securities in accordance with the intended plan of distribution thereof, and pursuant thereto the Company shall, as soon as reasonably practicable:

3.1.1 prepare and file with the SEC as soon as practicable a Registration Statement with respect to such Registrable Securities and use its commercially reasonable efforts to cause such Registration Statement to become effective and remain effective until all Registrable Securities have ceased to be Registrable Securities;

3.1.2 prepare and file with the SEC such amendments and post-effective amendments to the Registration Statement, and such supplements to the Prospectus, as may be reasonably requested by any Holder or any Underwriter of Registrable Securities or as may be required by the rules, regulations or instructions applicable to the registration form used by the Company or by the Securities Act or rules and regulations thereunder to keep the Registration Statement effective until all Registrable Securities covered by such Registration Statement are sold in accordance with the intended plan of distribution set forth in such Registration Statement or supplement to the Prospectus;

3.1.3 at least two (2) Business Days prior to filing a Registration Statement or Prospectus, or any amendment or supplement thereto, furnish without charge to the Underwriters, if any, and the Holders of Registrable Securities included in such Registration, and such Holders’ legal counsel, if any, copies of such Registration Statement as proposed to be filed, each amendment and supplement to such Registration Statement (in each case including all exhibits thereto and documents incorporated by reference therein), the Prospectus included in such Registration Statement (including each preliminary Prospectus), and such other documents as the Underwriters and the Holders of Registrable Securities included in such Registration or the legal counsel for any such Holders may request in order to facilitate the disposition of the Registrable Securities owned by such Holders; provided that in no event shall the Company be required to delay or postpone the filing of such Registration Statement or Prospectus as a result of or in connection with such Holders’ review;

3.1.4 prior to any public offering of Registrable Securities, use its commercially reasonable efforts to (i) register or qualify the Registrable Securities covered by the Registration Statement under such securities or “blue sky” laws of such jurisdictions in the United States as the Holders of Registrable Securities included in such Registration Statement (in light of their intended plan of distribution) may reasonably request (or provide evidence satisfactory to such Holders that the Registrable Securities are exempt from such registration or qualification) and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to be registered with or approved by such other Governmental Entities as may be necessary by virtue of the business and operations of the Company and do any and all other acts and things that may be necessary or advisable to enable the Holders of Registrable Securities included in such Registration Statement to consummate the disposition of such Registrable Securities in such jurisdictions; provided, however, that the Company shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify or take any action to which it would be subject to general service of process or taxation in any such jurisdiction where it is not then otherwise so subject;

3.1.5 cause all such Registrable Securities to be listed on each national securities exchange on which similar securities issued by the Company are then listed;

3.1.6 provide a transfer agent or warrant agent, as applicable, registrar and a CUSIP number for all such Registrable Securities no later than the effective date of such Registration Statement;

3.1.7 advise each seller of such Registrable Securities, within five (5) Business Days after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the SEC suspending the effectiveness of such Registration Statement or the initiation or threatening of any Legal Proceeding for such purpose and promptly use its commercially reasonable efforts to prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued;

3.1.8 notify the Holders, within five (5) Business Days, at any time when a Prospectus relating to such Registration Statement is required to be delivered under the Securities Act, of the happening of any event as a result of which the Prospectus included in such Registration Statement, as then in effect, includes a Misstatement, and then to correct such Misstatement as set forth in Section 3.5;

3.1.9 in the event of an Underwritten Offering, in each of the following cases to the extent customary for a transaction of its type, permit the Sponsor, Ambipar Parent, the Underwriters or other financial institutions facilitating such Underwritten Offering, if any, and any attorney, consultant or accountant retained by the Sponsor, Ambipar Parent or Underwriters to participate, at each such Person’s own expense, in the preparation of the Registration Statement, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such representative, Underwriter, financial institution, attorney, consultant or accountant in connection with the Underwritten Offering; provided, however, that such representatives, Underwriters or financial institutions agree to confidentiality arrangements in form and substance reasonably satisfactory to the Company, prior to the release or disclosure of any such information;

3.1.10 in the event of an Underwritten Offering, permit the Sponsor and Ambipar Parent, as applicable, to rely on any comfort letter from the Company’s independent registered public accounting firms provided to the managing Underwriter of such offering;

3.1.11 in the event of an Underwritten Offering, on the date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion and negative assurance letter, dated such date, of counsel representing the Company for the purposes of the Underwritten Offering, addressed to the Underwriters, if any, covering such legal matters with respect to the Underwritten Offering in respect of which such opinion is being given as the Underwriter may reasonably request and as are customarily included in such opinions and negative assurance letters;

3.1.12 in the event of any Underwritten Offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing Underwriter of such offering;

3.1.13 in the event of any Underwritten Offering, use its commercially reasonable efforts to make available senior executives of the Company to participate in customary “road show” presentations that may be reasonably requested by the Underwriter in such Underwritten Offering; and

3.1.14 otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the participating Holders, consistent with the terms of this Agreement, in connection with such Registration.

3.2 Registration Expenses. The Registration Expenses of all Registrations shall be borne by the Company. It is acknowledged by the Holders that the Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters’ commissions and discounts, brokerage fees, Underwriter marketing costs and, other than as set forth in the definition of “Registration Expenses,” all reasonable and documented fees and expenses of any legal counsel representing the Holders (as well as of any attorney, consultants or consultant retained by the Holders under Section 3.1.9 or otherwise).

3.3 Share Distributions. In connection with any Shelf, if the Company shall receive a request from a Holder included therein to effectuate a pro rata in-kind distribution or other similar Transfer for no consideration of such Registrable Securities pursuant to such Registration to its members, partners or shareholders, as the case may be, then the Company shall deliver or cause to be delivered to the transfer agent and registrar for the Registrable Securities an opinion of counsel to the Company reasonably acceptable to such transfer agent and registrar that any legend referring to the Securities Act may be removed upon such distribution or other Transfer of such Registrable Securities pursuant to such Registration; provided that the distributee or transferee of such Registrable Securities is not and has not been for the preceding ninety (90) calendar days an affiliate of the Company (as defined in Rule 405 promulgated under the Securities Act). The Company’s obligations hereunder are conditioned upon the receipt of a representation letter reasonably acceptable to the Company from such Holder regarding such proposed pro rata in-kind distribution or other similar Transfer for no consideration of such Registrable Securities.

3.4 Requirements for Participation in Registration Statement in Offerings. Notwithstanding anything in this Agreement to the contrary, if any Holder does not provide the Company with its requested Holder Information, the Company may exclude such Holder’s Registrable Securities from the applicable Registration Statement or Prospectus if the Company determines, based on the advice of counsel, that such information is necessary to effect the Registration and such Holder continues thereafter to withhold such information. Notwithstanding anything in this Agreement, the exclusion of a Holder’s Registrable Securities as a result of this Section 3.4 shall not affect the Registration of the other Registrable Securities to be included in such Registration.

3.5 Suspension of Sales; Adverse Disclosure; Restrictions on Registration Rights.

3.5.1 Upon receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, each of the Holders shall forthwith discontinue disposition of Registrable Securities until it has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as reasonably practicable after the time of such notice), or until it is advised in writing by the Company that the use of the Prospectus may be resumed.

3.5.2 Subject to Section 3.5.3, if the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would (a) require the Company to make an Adverse Disclosure, (b) require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control, or (c) in the good faith judgment of the majority of the Board, upon the advice of external legal counsel, be seriously detrimental to the Company and the majority of the Board concludes as a result that it is essential to defer such filing, initial effectiveness or continued use at such time, the Company may, upon giving prompt written notice of such action to the Holders (which notice shall not specify the nature of the event giving rise to such delay or suspension), delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time determined in good faith by the Company to be necessary for such purpose. In the event the Company exercises its rights under this Section 3.5.2, the Holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable Securities until such Holder receives written notice from the Company that such sales or offers of Registrable Securities may be resumed, and in each case maintain the confidentiality of such notice and its contents.

3.5.3 The right to delay or suspend any filing, initial effectiveness or continued use of a Registration Statement pursuant to Section 3.5.2 shall be exercised by the Company, in the aggregate, for not more than three (3) occasions, for not more than ninety (90) consecutive calendar days or for not more than one hundred and fifty (150) total calendar days, in each case, during any twelve (12)-month period.

3.6 Reporting Obligations. As long as any Registrable Securities remain outstanding, the Company, at all times while it shall be a reporting company under the Exchange Act, shall use reasonable efforts to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings; provided that any documents publicly filed or furnished with the SEC pursuant to the Electronic Data Gathering, Analysis and Retrieval System shall be deemed to have been furnished or delivered to the Holders pursuant to this Section 3.6. The Company further covenants that it shall use reasonable efforts to take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell Class A Ordinary Shares held by such Holder without Registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule then in effect).

4. Indemnification and Contribution

4.1 The Company agrees to indemnify, to the extent permitted by law, each participating Holder, its directors, officers, partners, managers, members, investment advisors, employees, shareholders and each Person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and reasonable and documented out of pocket expenses (including, without limitation, reasonable and documented outside attorneys’ fees of one (1) law firm) arising from, in connection with, or relating to any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of a Prospectus, in the light of the circumstances under which they were made) not misleading, except insofar as the same are caused by or contained in any information so furnished in writing to the Company or on behalf of such Holder expressly for use therein or such Holder has omitted a material fact from such information or otherwise violated the Securities Act, Exchange Act or any state securities law or any other law, rule or regulation thereunder; provided, however, that the indemnification contained in this Section 4.1 shall not apply to amounts paid in settlement of any losses, claims, damages, liabilities and out of pocket expenses if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld, conditioned or delayed), nor shall the Company be liable for any losses, claims, damages, liabilities and out of pocket expenses to the extent they arise out of or are based upon a violation which occurs (A) in connection with any failure of such Holder to deliver or cause to be delivered a Prospectus made available by the Company in a timely manner, (B) 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 the Company, or (C) in connection with any offers or sales effected by or on behalf of a Holder in violation of Section 3.5.1 hereof.

4.2 In connection with any Registration Statement in which a Holder is participating, such Holder shall furnish (or cause to be furnished) to the Company in writing such information as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus (the “Holder Information”) and, to the extent permitted by law, shall indemnify the Company, its directors, officers and agents and each Person who controls the Company (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and reasonable and documented out of pocket expenses (including, without limitation, reasonable outside attorneys’ fees of one (1) law firm) arising from, in connection with, or relating to any untrue or alleged untrue statement of material fact contained or incorporated by reference in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of a Prospectus, in the 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 so furnished in writing by or on behalf of such Holder expressly for use therein; provided, however, that the obligation to indemnify shall be several, not joint, among such Holders, and the liability of each such Holder shall be in proportion to and limited to the net proceeds received by such Holder from the sale of Registrable Securities giving rise to such indemnification obligation.

4.3 Any Person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any Person’s right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld, conditioned or delayed). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one (1) outside counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) 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 Legal Proceeding.

4.4 The indemnification provided for under this Section 4 shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and shall survive the Transfer of Registrable Securities.

4.5 If the indemnification provided under this Section 4 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses 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, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations; provided, however, that the liability of the Holder shall be limited to the net proceeds received by such Holder from the sale of Registrable Securities giving rise to such indemnification obligation. 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 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 Section 4.1, Section 4.2 and Section 4.3 above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any Legal 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.

5. Transfer Restrictions.

5.1 Lock-Up.

5.1.1 Except as otherwise approved in writing by the Company and Opportunity in their sole discretion, each Holder and each Director Holder (each a “Lock-up Holder”) severally, and not jointly, agrees with the Company not to effect any Transfer, or make a public announcement of any intention to effect such Transfer, of any Lock-Up Securities (as defined below) Beneficially Owned or otherwise held by such Person during the Lock-Up Period (as defined below); provided, that such prohibition shall not apply to Transfers permitted pursuant to Section 5.2. The “Lock-Up Period” means, (i) in the case of each Holder and its Permitted Transferees, the period commencing on the Closing Date and ending on the third anniversary of the Closing Date, and (ii) in the case of each Director Holder and its Permitted Transferees, the period commencing on the Closing Date and ending on the first anniversary of the Closing Date. The “Lock-Up Securities” means, for any Lock-Up Holder, as the case may be, the Ordinary Shares and Private Placement Warrants Beneficially Owned or otherwise held by such Lock-Up Holder immediately following the Closing, including any Class A Ordinary Shares acquired as the result of the vesting of the Restricted Stock Units and, in the case of Xxxxxxxx, the Restricted Stock Units.

5.1.2 During the Lock-Up Period, any purported Transfer of Lock-Up Securities not in accordance with this Agreement shall be null and void, and the Company shall refuse to recognize any such Transfer for any purpose.

5.1.3 Each Lock-up Holder acknowledges and agrees that, notwithstanding anything to the contrary contained in this Agreement, the Lock-Up Securities Beneficially Owned or otherwise held by such Lock-up Holder shall remain subject to any restrictions on Transfer under applicable securities Laws of any Governmental Entity, including all applicable holding periods under the Securities Act and other rules of the SEC.

5.2 Permitted Transfers. Notwithstanding anything to the contrary contained in this Agreement, during the Lock-Up Period, a Lock-up Holder may Transfer, without the consent of the Company and Opportunity, any of such Lock-up Holder’s Lock-Up Securities to (i) any of such Lock-up Holder’s Permitted Transferees, upon written notice to the Company, or (ii) (a) in the case of an individual, by virtue of Laws of descent and distribution upon death of the individual; (b) in the case of an individual, pursuant to a qualified domestic relations order; or (c) pursuant to any liquidation, merger, share exchange or other similar transaction (other than the Mergers) which results in all of the Company’s shareholders having the right to exchange their Ordinary Shares or other equity securities of the Company for cash, securities or other property; provided, that in connection with any Transfer of such Lock-Up Securities pursuant to clause (ii) above, (x) the restrictions and obligations contained in Section 5.1 and this Section 5.2 will continue to apply to such Lock-Up Securities (including any other securities acquired in exchange therefor) after any Transfer of such Lock-Up Securities and such Transferee shall agree to be bound by such restrictions and obligations by executing and delivering a joinder agreement substantially in the form attached as Exhibit A or such other form as is reasonably acceptable to the Company, and (y) the Transferee of such Lock-Up Securities shall have no rights under this Agreement, unless, for the avoidance of doubt, such Transferee is a Permitted Transferee in accordance with this Agreement. Any Transferee of Lock-Up Securities who is a Permitted Transferee of the Transferor pursuant to this Section 5.2 shall be required, at the time of and as a condition to such Transfer, to become a party to this Agreement by executing and delivering a joinder agreement substantially in the form attached as Exhibit A or such other form as is reasonably acceptable to the Company, whereupon such Transferee will be treated as a party (with the same rights and obligations as the Transferor) for all purposes of this Agreement. Notwithstanding the foregoing provisions of this Section 5.2, a Lock-up Holder may not make a Transfer to a Permitted Transferee if such Transfer has as a purpose the avoidance of or is otherwise undertaken in contemplation of avoiding the restrictions on Transfers in this Agreement (it being understood that the purpose of this provision includes prohibiting the Transfer to a Permitted Transferee (A) that has been formed to facilitate a material change with respect to who or which entities Beneficially Own the underlying Lock-Up Securities, or (B) followed by a change in the relationship between such Lock-up Holder and such Permitted Transferee (or a change of control of such Lock-up Holder or Permitted Transferee) after the Transfer with a result and effect that such Lock-up Holder has indirectly made a Transfer of Lock-Up Securities by using a Permitted Transferee, which Transfer would not have been directly permitted under this Section 5 had such change in such relationship occurred prior to such Transfer).

5.3 Legends. Each Lock-up Holder agrees that its Lock-up Securities shall include customary transfer legends on any certificates reflecting the restrictions on Transfer set forth in this Section 5; provided, that at the time that any time such restrictions on Transfer lapse pursuant to this Section 5, the Company shall remove any such legends, share transfer restrictions, stop transfer orders or similar restrictions with respect to the applicable Lock-up Securities held by such Lock-up Holder, as the case may be.

5.4 Compliance with Laws. Notwithstanding any other provision of this Agreement, each Lock-up Holder agrees that it will comply with the Securities Act and other applicable Laws in connection with any Transfer by such Lock-up Holder of any equity securities of the Company Beneficially Owned or otherwise held by such Lock-up Holder.

6. Executive Committee.

6.1 The parties hereto agree to cause the Board to establish an advisory executive committee which shall be available to advise the Board on Company matters related to strategy, capital allocation, operations, mergers and acquisitions and subsequent integrations (the “Executive Committee”). The Executive Committee shall be comprised of up to four (4) members. For as long as Opportunity is entitled under the terms of the Articles to appoint a member of the Board and effectively appoints such member of the Board, Opportunity shall be entitled to designate one (1) member of the Executive Committee. For so long as the Sponsor is entitled under the terms of the Articles to appoint a member of the Board and effectively appoints such member of the Board, the Sponsor shall be entitled to designate one (1) member of the Executive Committee. For so long as Ambipar Parent is entitled under the terms of the Articles to appoint a member of the Board and effectively appoints such member of the Board, Ambipar Parent shall be entitled to designate two (2) members of the Executive Committee. In the event that any of Opportunity, Sponsor or Ambipar Parent ceases to be entitled to designate a member to the Executive Committee pursuant to the terms hereof, the Board shall be entitled to designate such member at its discretion.

6.2 The Executive Committee shall meet, preferably, once every month. The Executive Committee shall adopt decisions and recommendations by majority vote of its members; provided that the decisions and recommendations of the Executive Committee shall, under no circumstances, have any binding effect on the Board or the Company, and shall serve an advisory purpose only.

7. Miscellaneous.

7.1 Confidentiality. Each Holder, Director Holder and the Company agree that any information obtained pursuant to this Agreement (including any information about any proposed Registration or offering pursuant to Section 2) will not be disclosed or used for any purpose other than the exercise of rights under this Agreement provided that any such information may be disclosed on a confidential basis to its directors, officers, employees, representatives and legal counsel or as required by Law.

7.2 Further Assurances. Each of the parties hereto shall perform such further acts and execute such further documents as may reasonably be necessary to carry out and give full effect to the provisions of this Agreement and the intentions of the parties as reflected thereby.

7.3 Governing Law. NOTWITHSTANDING THE PLACE WHERE THIS AGREEMENT MAY BE EXECUTED BY ANY OF THE PARTIES HERETO, THE PARTIES EXPRESSLY AGREE THAT (1) THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED UNDER THE LAWS OF THE STATE OF NEW YORK AND (2) THE VENUE FOR ANY ACTION TAKEN WITH RESPECT TO THIS AGREEMENT SHALL BE ANY New York state court sitting in the CITY OF NEW YORK, borough of Manhattan, or, if, under applicable Law, exclusive jurisdiction is vested in the federal courts, the United States District Court for the Southern District of New York (and appellate courts thereof).

7.4 Waiver of Jury Trial. EACH PARTY HERETO ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND, THEREFORE, EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT TO ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

7.5 Successors and Assigns; Assignment.

7.5.1 Except as otherwise expressly set forth in this Agreement, the provisions hereof shall inure to the benefit of, and be binding upon, the successors, assigns, heirs, executors, and administrators of the parties hereto.

7.5.2 None of the rights, privileges, or obligations set forth in, arising under, or created by this Agreement may be assigned or Transferred without the prior consent in writing of each party to this Agreement, with the exception of assignments and transfers from a Lock-up Holder to any of its Permitted Transferees.

7.5.3 Notwithstanding anything in this Section 7.5, (a) any Permitted Transferee shall, in connection with their assignment or transfer of Ordinary Shares, execute a Joinder Agreement to be entered into between the Company and such Permitted Transferee at the time of the applicable Transfer, pursuant to which such Permitted Transferee shall be deemed to be a party to this Agreement, and (b) any other Person Beneficially Owning or otherwise holding any Registrable Securities may, at the Company’s request, execute a Joinder Agreement with the Company, pursuant to which such Person shall be deemed to be a party to this Agreement. Failure to comply with this Section 7.5.3 shall relieve the Company of its obligations under this Agreement with respect to such Permitted Transferee. Unless otherwise noted in the applicable Joinder Agreement, each Permitted Transferee of a Holder shall be deemed a Holder.

7.6 Amendment and Waiver. Any term of this Agreement may be amended and the observance of any term hereof may be waived (either prospectively or retroactively and either generally or in a particular instance) with the written consent of the Company and the Holders holding a majority-in-interest of the Registrable Securities; provided, however, that notwithstanding the foregoing, any amendment hereto or waiver hereof that adversely affects one Holder or a group of Holders, or one Lock-up Holder or group of Lock-up Holders, solely in its or their capacity as a Beneficial Owner or holder equity securities of the Company, in a manner that is materially different from the other Holders or Lock-up Holders (in such capacity) shall require the consent of each Holder or Lock-up Holders so affected.

7.7 Other Registration Rights. Other than the PIPE Investors who have registration rights with respect to their PIPE Shares and the Ambipar Parent PIPE Shares pursuant to their respective Subscription Agreements, the Company represents and warrants that no Person, other than a Holder, has any right to require the Company to register any securities of the Company for sale or to include such securities of the Company in any Registration Statement filed by the Company for the sale of securities for its own account or for the account of any other Person following the Closing Date. Further, the Company represents and warrants that this Agreement supersedes any other registration rights agreement or agreement with similar terms and conditions and in the event of a conflict between any such agreement or agreements and this Agreement, the terms of this Agreement shall prevail.

7.8 Termination. This Agreement will automatically terminate upon the earlier to occur of (i) the tenth (10^th) anniversary of the date of this Agreement, (ii) any acquisition of the Company, including by way of merger or consolidation, after the Closing, as a result of which the Registrable Securities, are converted into the right to receive consideration consisting solely of cash or other property other than securities listed on a national securities exchange registered under Section 6 of the Exchange Act, (iii) with respect to any Holder, on the date that such Holder no longer holds any Registrable Securities or (iv) with respect to any Lock-up Holder (in such capacity and in respect of the transfer restrictions pursuant to Section 5 hereof) on the expiration of the Lock-up Period.

7.9 Holder Information. Each Holder agrees, if requested in writing, to represent to the Company the total number of Registrable Securities, held by such Holder in order for the Company to make determinations hereunder.

7.10 Notices. All notices and other communications required or permitted hereunder to be given to a party to this Agreement shall be in writing and shall be mailed by registered mail, postage prepaid, or otherwise delivered by electronic mail, hand or by messenger, addressed to such party’s address as set forth in the shareholders register maintained by the Company or at such other address with respect to a party as such party shall notify each other party in writing as above provided.

No failure or delay of a 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 thereof or the exercise of any other right or power. Any waiver, permit, consent, or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. The rights and remedies of the parties hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have hereunder.

7.12 Severability. In the event that any term, provision, covenant or restriction of this Agreement, or the application thereof, is held to be illegal, invalid or unenforceable under any present or future Legal Requirement: (i) such provision will be fully severable; (ii) this Agreement will be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part hereof; (iii) the remaining provisions of this Agreement will remain in full force and effect and will not be affected by the illegal, invalid or unenforceable provision or by its severance herefrom; and (iv) in lieu of such illegal, invalid or unenforceable provision, there will be added automatically as a part of this Agreement a legal, valid and enforceable provision as similar in terms of such illegal, invalid or unenforceable provision as may be possible.

7.13 Counterparts; Electronic Execution. This Agreement may be executed in multiple counterparts (including by facsimile or electronic transmission (including .pdf file, .jpeg file, Adobe Sign, or DocuSign)), all of which shall be considered one and the same document and shall become effective when one or more counterparts have been signed by each of the parties hereto and delivered to the other parties, it being understood that all parties need not sign the same counterpart. Delivery by electronic transmission to counsel for the other parties of a counterpart executed by a party shall be deemed to meet the requirements of the previous sentence.

7.14 Aggregation of Shares. All Ordinary Shares held by affiliated Persons shall be aggregated together for the purpose of determining the availability of any rights under this Agreement.

7.15 No Third-Party Beneficiaries. Except as expressly provided in this Agreement, this Agreement (including the documents and instruments referred to herein) is not intended to confer on any Persons other than the parties hereto any rights, remedies, obligations or liabilities hereunder.

7.16 Mutual Drafting. This 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.

7.17 Effectiveness; Entire Agreement; Restatement. This Agreement shall become effective as of the Closing and prior thereto shall be of no force or effect. If the Business Combination Agreement is terminated in accordance with its terms prior to the Closing, this Agreement shall automatically terminate and be of no force or effect. Upon Closing (i) this Agreement shall constitute the full and entire agreement and understanding between the parties with respect to the subject matter hereof and supersedes all and any prior agreements and understandings relating to such subject matter, (ii) each of the SPAC and the SPAC Holders agrees that this Agreement shall supersede and replace in its entirety the terms and conditions of the SPAC RRA and (iii) the SPAC RRA shall no longer be of any force or effect.

7.18 Adjustments. If, and as often as, there are any changes in the Registrable Securities by way of share split, share dividend, combination or reclassification, or through merger, consolidation, reorganization, recapitalization or sale, or by any other means, appropriate adjustment shall be made in the provisions of this Agreement, as may be required, so that the rights, privileges, duties and obligations hereunder shall continue with respect to the Registrable Securities as so changed.
