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, any Holder named therein. Subject to Sections 2.1.2 and 3.4 hereof, the Company shall maintain a Shelf in accordance with the terms hereof, and shall prepare and file with the Commission such amendments, including post-effective amendments, and supplements as may be necessary to keep a Shelf continuously effective, available for use by 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. In the event the Company files a Form S-1 Shelf, the Company shall use its commercially reasonable efforts to convert the Form S-1 Shelf (and any Subsequent Shelf Registration) to a Form S-3 Shelf as soon as reasonably practicable after the Company is eligible to use Form S-3.

2.1.2 Subsequent Shelf Registration. 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, subject to Section 3.4 hereof, 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”) registering the resale of all Registrable Securities under such Shelf (determined as of two Business Days prior to such filing), and pursuant to any method or combination of methods legally available to, and requested by, any Holder named therein. If a Subsequent Shelf Registration is filed, the Company shall use its commercially reasonable efforts to (i) cause such Subsequent Shelf Registration to become effective under the Securities Act as promptly as is reasonably practicable after the filing thereof (it being agreed that the Subsequent Shelf Registration shall be an automatic shelf registration statement (as defined in Rule 405 promulgated under the Securities Act) if the Company is a well-known seasoned issuer (as defined in Rule 405 promulgated under the Securities Act) at the most recent applicable eligibility determination date) and (ii) keep such Subsequent Shelf Registration continuously effective, available for use by 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. Any such Subsequent Shelf Registration shall be on Form S-3, to the extent that the Company is eligible to use such form. Otherwise, such Subsequent Shelf Registration shall be on another appropriate form.

Subject to Section 3.4 hereof, in the event that any Holder or Holders, collectively, hold Registrable Securities that are not registered for resale on a delayed or continuous basis, the Company, upon request of any such Holder or Holders, shall promptly use its commercially reasonable efforts to cause the resale of such Registrable Securities to be covered by either, at the Company’s option, any then-available Shelf (including by means of a post-effective amendment) or a Subsequent Shelf Registration and cause the same to become effective as soon as practicable after such filing and such Shelf or Subsequent Shelf Registration shall be subject to the terms hereof; provided, however, that (i) the Company shall only be required to cause such Registrable Securities to be covered if the total offering price thereof is reasonably expected to exceed, in the aggregate, $25 million and (ii) the Company shall only be required to register Registrable Securities pursuant to this Section 2.1.3 twice per calendar.

Following the expiration of the Founder Shares Lock-up Period, the BVF Lock-up Period, the New Holders Lock-up Period or the Private Placement Lock-up Period, as applicable, at any time and from time to time when an effective Shelf is on file with the Commission, any New Holder, Existing Holder, BVF or the Sponsor, or any combination thereof (any of the New Holders, Existing Holders, BVF or the Sponsor making such demand, a “Demanding Holder”) may request to sell all or any portion of its Registrable Securities in an Underwritten Offering or other coordinated offering that is registered pursuant to a Shelf (each, an “Underwritten Shelf Takedown”); provided that the Company shall only be obligated to effect an Underwritten Shelf Takedown if such offering shall include (a) 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, $25 million (the “Minimum Takedown Threshold”) or (b) if the Demanding Holders hold Registrable Securities with a total offering price reasonably expected to be less than the Minimum Takedown Threshold, all of the Registrable Securities held by a Demanding Holder. All requests for Underwritten Shelf Takedowns shall be made by giving written notice to the Company, which shall specify the approximate number of Registrable Securities proposed to be sold in the Underwritten Shelf Takedown. The Company shall have the right to select the Underwriters for such offering (which shall consist of one or more reputable nationally recognized investment banks), subject to the prior approval by the Demanding Holder(s) (which shall not be unreasonably withheld, conditioned or delayed). The New Holders and BVF, collectively, on the one hand, and the Existing Holders and the Sponsor, collectively, on the other hand, may each demand Underwritten Shelf Takedowns pursuant to this Section 2.1.4 (i) not more than three times in any 12-month period (the “Yearly Limit”) and (ii) not more than five times in the aggregate (the “Total Limit”). Notwithstanding anything to the contrary in this Agreement, the Company may effect any Underwritten Offering pursuant to any then-effective Registration Statement, including a Form S-3, which is then available for such offering.

If the managing Underwriter or Underwriters in an Underwritten Shelf Takedown, in good faith, advises the Company, the Demanding Holder(s) and the Holders requesting piggy back rights pursuant to this Agreement with respect to such Underwritten Shelf Takedown (the “Requesting Holders”) (if any) in writing that the dollar amount or number of Registrable Securities that the Demanding Holder(s) 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 such Underwritten Offering pursuant to separate written contractual piggy-back registration rights held by any other stockholders who desire to sell, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten Offering 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 such Underwritten Offering, 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 the Demanding Holders and the Requesting Holders (if any) (pro rata based on the respective number of Registrable Securities that each Demanding Holder and Requesting Holder (if any) has requested be included in such Underwritten Shelf Takedown and the aggregate number of Registrable Securities that the Demanding Holders and Requesting Holders (if any) have requested be included in such Underwritten Shelf Takedown) that can be sold without exceeding the Maximum Number of Securities.

2.1.6 Underwritten Shelf Takedown Withdrawal. Prior to the filing of the applicable “red xxxxxxx” prospectus or prospectus supplement used for marketing such Underwritten Shelf Takedown, a majority-in-interest of the Demanding Holders initiating an Underwritten Shelf Takedown shall have the right to withdraw from such Underwritten Shelf Takedown 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 such Underwritten Shelf Takedown; provided that any other Demanding Holder(s) may elect to have the Company continue an Underwritten Shelf Takedown if the Minimum Takedown Threshold would still be satisfied by the Registrable Securities proposed to be sold in the Underwritten Shelf Takedown by the Demanding Holder(s). If withdrawn, a demand for an Underwritten Shelf Takedown shall constitute a demand for an Underwritten Shelf Takedown by the withdrawing Demanding Holder for purposes of Section 2.1.4 hereof and shall count toward the Yearly Limit and the Total Limit, unless either (i) the Demanding Holder(s) making the withdrawal has not previously withdrawn any Underwritten Shelf Takedown or (ii) the Demanding Holder(s) making the withdrawal reimburses the Company for all Registration Expenses with respect to such Underwritten Shelf Takedown (or, if there is more than one Demanding Holder, a pro rata portion of such Registration Expenses based on the respective number of Registrable Securities that each Demanding Holder has requested be included in such Underwritten Shelf Takedown); provided that, if any other Demanding Holder(s) elects to continue an Underwritten Shelf Takedown pursuant to the proviso in the immediately preceding sentence, such Underwritten Shelf Takedown shall instead count as an Underwritten Shelf Takedown demanded by the Demanding Holders for purposes of Section 2.1.4 hereof and shall count toward the Yearly Limit and the Total Limit. Following the receipt of any Withdrawal Notice, the Company shall promptly forward such Withdrawal Notice to any other Demanding Holders and Requesting Holders. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a Shelf Takedown prior to its withdrawal under this Section 2.1.6, other than if a Demanding Holder elects to pay such Registration Expenses pursuant to clause (ii) of the second sentence of this Section 2.1.6.

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 Underwritten Offering by the Company. For the avoidance of doubt, the notice periods set forth in this Section 2.2.1 shall not apply to an Underwritten Shelf Takedown conducted in accordance with Section 2.1.4 or Block Trades conducted in accordance with Section 2.4.

2.2.2 Reduction of Piggyback Registration. If the managing Underwriter or Underwriters in an Underwritten Offering that is to be a Piggyback Registration, in good faith, advise(s) the Company and the Holders of Registrable Securities participating in the Piggyback Registration in writing that the dollar amount or number of Class A ordinary shares or other equity securities that the Company or the Demanding Holders desire to sell, taken together with (i) the number of Class A ordinary shares or other equity securities, if any, as to which Registration or a registered offering has been demanded pursuant to separate written contractual arrangements with persons or entities other than the Holders of Registrable Securities hereunder, (ii) the Registrable Securities as to which Registration has been requested pursuant to Section 2.2.1 and (iii) the number of Class A ordinary shares or other equity securities, if any, as to which Registration or a registered offering has been requested pursuant to separate written contractual piggy-back registration rights of persons or entities other than the Holders of Registrable Securities hereunder, exceeds the Maximum Number of Securities, then:

(a) if the Registration or registered offering is undertaken for the Company’s account, the Company shall include in any such Registration or registered offering (A) first, the number of Class A ordinary shares or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to Section 2.2.1 hereof, pro rata, based on the respective number of Registrable Securities that each Holder has requested be included in such Underwritten Offering and the aggregate number of Registrable Securities that the Holders have requested to be included in such Underwritten Offering, which can be sold without exceeding the Maximum Number of Securities; and (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the number of Class A ordinary shares or other equity securities, if any, as to which Registration or a registered offering has been requested pursuant to separate written contractual piggy-back registration rights of persons or entities other than the Holders of Registrable Securities hereunder, which can be sold without exceeding the Maximum Number of Securities;

(b) if the Registration or registered offering is pursuant to a request by persons or entities other than the Holders of Registrable Securities, then the Company shall include in any such Registration or registered offering (A) first, the number of Class A ordinary shares or other equity securities, if any, of such requesting persons or entities, other than the Holders of Registrable Securities, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to Section 2.2.1 hereof, pro rata, based on the respective number of Registrable Securities that each Holder has requested be included in such Underwritten Offering and the aggregate number of Registrable Securities that the Holders have requested to be included in such Underwritten Offering, which can be sold without exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the number of Class A ordinary shares or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C), the number of Class A ordinary shares or other equity securities, if any, as to which Registration or a registered offering has been requested pursuant to separate written contractual piggy-back registration rights of such persons or entities other than the Holders of Registrable Securities hereunder, which can be sold without exceeding the Maximum Number of Securities; and

(c) if the Registration or registered offering is pursuant to a request by Holder(s) of Registrable Securities pursuant to Section 2.1 hereof, then the Company shall include in any such Registration or registered offering securities in the priority set forth in Section 2.1.5 hereof.

2.2.3 Piggyback Registration Withdrawal. Any Holder of Registrable Securities (other than a Demanding Holder, whose right to withdraw from an Underwritten Shelf Takedown, and related obligations, shall be governed by Section 2.1.6 hereof) shall have the right to withdraw from a Piggyback Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of his, her or its intention to withdraw from such Piggyback Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Piggyback Registration or, in the case of a Piggyback Registration pursuant to a Shelf Registration, the filing of the applicable “red xxxxxxx” prospectus or prospectus supplement with respect to such Piggyback Registration used for marketing such transaction. The Company (whether on its own good faith determination or as the result of a request for withdrawal by persons or entities pursuant to separate written contractual obligations) may withdraw a Registration Statement filed with the Commission in connection with a Piggyback Registration at any time prior to the effectiveness of such Registration Statement. Notwithstanding anything to the contrary in this Agreement (other than Section 2.1.6 hereof), the Company shall be responsible for the Registration Expenses incurred in connection with the Piggyback Registration prior to its withdrawal under this Section 2.2.3.

2.2.4 Unlimited Piggyback Registration Rights. For purposes of clarity, subject to Section 2.1.6 hereof, any Piggyback Registration effected pursuant to Section 2.2 hereof shall not be counted as a demand for an Underwritten Shelf Takedown under Section 2.1.4 hereof and shall not count toward the Yearly Limit or the Total Limit.

2.3 Market Stand-off. In connection with any Underwritten Offering of equity securities of the Company (other than a Block Trade) or any Company-initiated Registration for the account of the Company (subject to the Company’s compliance with Section 2.2 hereof), each Holder that is an executive officer, director or Holder in excess of 5% of the then-outstanding Class A ordinary shares (calculated, in the case of each New Holder, as if all of its Class C ordinary shares and Retained Company Shares are exchanged for Class A ordinary shares) 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 Company, during the 90-day period (or such shorter time agreed to by the managing Underwriters) beginning on the date of pricing of such offering (the “Underwritten Lock-up Period”), except as expressly permitted by such lock-up agreement or in the event the Underwriters managing the offering otherwise consent in writing. Each 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 the Company’s directors and executive officers or the other stockholders of the Company). The Company will not be obligated to undertake an Underwritten Shelf Takedown during any Underwritten Lock-up Period binding on the Holders, nor will the Company be obligated to include in any Piggyback Registration any Registrable Securities that are then subject to a “lock-up” agreement.

2.4 Block Trades.

2.4.1 Notwithstanding any other provisions of this Agreement, but subject to Section 3.4, if a Demanding Holder desires to effect a Block Trade, with a total offering price reasonably expected to exceed, in the aggregate, either (x) the Minimum Takedown Threshold or (y) all remaining Registrable Securities held by such Demanding Holder, then notwithstanding the time periods provided for in Section ‎2.2.1, such Demanding Holder only needs to notify the Company of the Block Trade at least three (3) business days prior to the day such offering is to commence and the Company shall as promptly as is reasonably practicable, use its commercially reasonable efforts to facilitate such Block Trade; provided that the Demanding Holder wishing to engage in the Block Trade shall use its commercially reasonable efforts to work with the Company and any Underwriters or placement agents or sales agents prior to making such request in order to facilitate preparation of the registration statement, prospectus and other offering documentation related to such Block Trade.

2.4.2 Prior to the filing of the applicable “red xxxxxxx” prospectus or prospectus supplement used in connection with a Block Trade, the Demanding Holder that initiated such Block Trade shall have the right to submit a Withdrawal Notice to the Company and the Underwriter or Underwriters or placement agents or sales agents (if any) of their intention to withdraw from such Block Trade. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a block trade prior to its withdrawal under this Section ‎2.4.2 in the first instance of any such withdrawal; provided, that the Holder shall be responsible for the Registration Expenses incurred in connection with a block trade prior to any subsequent withdrawal under this Section 2.4.2.

2.4.3 Notwithstanding anything to the contrary in this Agreement, Section ‎2.2 hereof shall not apply to a Block Trade initiated by a Demanding Holder pursuant to this Agreement.

2.4.4 The Demanding Holder wishing to engage in a Block Trade shall have the right to select the Underwriters, placement agents or sales agents (if any) for such Block Trade (which shall consist of one or more reputable nationally recognized investment banks), provided, that such selection shall be subject to the consent of the Company, which consent shall not be unreasonably withheld, conditioned or delayed.

2.4.5 A Holder in the aggregate may demand no more than two Block Trades pursuant to this Section 2.4 in any 12-month period. For the avoidance of doubt, any Block Trade effected pursuant to this Section 2.4 shall not be counted as a demand for an Underwritten Shelf Takedown pursuant to Section 2.14 hereof.

Article III
COMPANY PROCEDURES

3.1 General Procedures. In connection with any Shelf and/or Shelf Takedown, 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 expeditiously as possible:

3.1.2 prepare and file with the Commission such amendments and post-effective amendments to the Registration Statement, and such supplements to the Prospectus, as may be reasonably requested by any Holder that holds at least 5% percent of the Registrable Securities registered on such Registration Statement 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 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, 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;

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 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 authorities or securities exchanges, including the applicable Nasdaq Stock Market, 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 or automated quotation system on which similar securities issued by the Company are then listed;

3.1.6 provide a transfer agent and registrar 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, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the Commission suspending the effectiveness of such Registration Statement or the initiation or threatening of any 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 at least three days (or in the case of a Block Trade, at least one day) prior to the filing of any Registration Statement or Prospectus or any amendment or supplement to such Registration Statement or Prospectus (or such shorter period of time as may be necessary in order to comply with the Securities Act, the Exchange Act and the rules and regulations promulgated under the Securities Act or Exchange Act, as applicable), furnish a copy thereof to each seller of such Registrable Securities or its counsel (excluding any exhibits thereto and any filing made under the Exchange Act that is to be incorporated by reference therein);

3.1.9 notify the Holders 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 3.4 hereof;

3.1.10 in the event of an Underwritten Offering, a Block Trade or other coordinated offering that is registered pursuant to a Registration Statement, permit a representative of the Holders (such representative to be selected by a majority-in-interest of the participating Holders), the Underwriters or other financial institutions facilitating such Underwritten Offering, Block Trade or other coordinated offering that is registered pursuant to a Registration Statement, if any, and any attorney or accountant retained by such Holders or Underwriter 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, attorney or accountant in connection with the Registration; provided, however, that such representatives or Underwriters enter into a confidentiality agreement, in form and substance reasonably satisfactory to the Company, prior to the release or disclosure of any such information;

3.1.11 obtain a “cold comfort” letter from the Company’s independent registered public accountants in the event of an Underwritten Offering, a Block Trade or other coordinated offering that is registered pursuant to a Registration Statement, in customary form and covering such matters of the type customarily covered by “cold comfort” letters as the managing Underwriter or other similar type of sales agent, placement agent or Underwriter may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating Holders;

3.1.12 in the event of an Underwritten Offering, a Block Trade or other coordinated offering that is registered pursuant to a Registration Statement, 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 such Registration, addressed to the placement agent or sales agent, if any, and the Underwriters, if any, covering such legal matters with respect to the Registration in respect of which such opinion is being given as the placement agent, sales agent, or Underwriter may reasonably request and as are customarily included in such opinions and negative assurance letters;

3.1.13 in the event of any Underwritten Offering, Block Trade or other coordinated offering that is registered pursuant to a Registration Statement, enter into and perform its obligations under an underwriting agreement, sales agreement or placement agreement, in usual and customary form, with the managing Underwriter, sales agent or placement agent of such offering;

3.1.14 make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least 12 months beginning with the first day of the Company’s first full calendar quarter after the effective date of the Registration Statement which satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any successor rule thereto);

3.1.15 with respect to an Underwritten Offering pursuant to Section 2.1.4 hereof, 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

3.1.16 otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the Holders participating in such Registration, in connection with such Registration.

Notwithstanding the foregoing, the Company shall not be required to provide any documents or information to an Underwriter or other sales agent or placement agent if such Underwriter or other sales agent or placement agent has not then been named with respect to the applicable Underwritten Offering or other coordinated offering that is registered pursuant to a Registration Statement.

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’ or agents’ commissions and discounts, brokerage fees, Underwriter marketing costs and, other than as set forth in the definition of “Registration Expenses,” all reasonable fees and expenses of any legal counsel representing the Holders, in each case pro rata based on the number of Registrable Securities that such Holders have sold in such Registration.

3.3 Requirements for Participation in Underwritten Offerings. Notwithstanding anything in this Agreement to the contrary, if any Holder does not timely provide the Company with its requested Holder Information (as defined below), 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. No person may participate in any Underwritten Offering or other coordinated offering for equity securities of the Company pursuant to a Registration initiated by the Company hereunder unless such person (i) agrees to sell such person’s securities on the basis provided in any arrangements approved by the Company and (ii) timely completes and executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting or other agreements and other customary documents as may be reasonably required under the terms of such arrangements. The exclusion of a Holder’s Registrable Securities as a result of this Section 3.3 shall not affect the registration of the other Registrable Securities to be included in such Registration.

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

3.4.1 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 he, she or 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 practicable after the time of such notice), or until he, she or it is advised in writing by the Company that the use of the Prospectus may be resumed.

3.4.2 Subject to Section 3.4.4, if the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would (i) require the Company to make an Adverse Disclosure, (ii) require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control or (iii) in the good faith judgment of the majority of the Board, 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 be required to 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 3.4.2, 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.

3.4.3 Subject to Section 3.4.4, if (i) during the period starting with the date 60 days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date 120 days after the effective date of, a Company-initiated Registration, and provided that the Company continues to actively employ, in good faith, all commercially reasonable efforts to maintain the effectiveness of the applicable Shelf, or (ii) if, pursuant to Section 2.1.4 hereof, Holders have requested an Underwritten Shelf Takedown and the Company and such Holders are unable to obtain the commitment of underwriters to firmly underwrite such offering, then, in each case, the Company may, upon giving prompt written notice of such action to the Holders, delay any other registered offering pursuant to Section 2.1.4 hereof.

3.4.4 The right to delay or suspend any filing, initial effectiveness or continued use of a Registration Statement pursuant to Section 3.4.2 or a registered offering pursuant to Section 3.4.3 shall be exercised by the Company, in the aggregate, not more than two (2) times or for more than sixty (60) consecutive calendar days, or for more than one hundred and twenty (120) total calendar days, in each case during any 12-month period.

3.5 Reporting Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to use commercially 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 Section 13(a) or 15(d) of the Exchange Act. The Company further covenants that it shall take such further action as any Holder may reasonably request, to the extent required from time to time to enable such Holder to sell Registrable Securities held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144.

Article IV
INDEMNIFICATION AND CONTRIBUTION

4.1 Indemnification.

4.1.1 The Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers and directors and each person or entity who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and reasonable out-of-pocket expenses (including, without limitation, reasonable outside attorneys’ fees) caused by any untrue or alleged untrue statement of material fact contained in 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 not misleading, except insofar as the same are caused by or contained in any information or affidavit so furnished in writing to the Company by such Holder expressly for use therein. The Company shall indemnify the Underwriters, their officers and directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to the indemnification of the Holder.

4.1.2 In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish (or cause to be furnished) to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus (the “Holder Information”) and, to the extent permitted by law, shall indemnify the Company, its directors, officers and agents and each person or entity who controls the Company (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and reasonable out-of-pocket expenses (including, without limitation, reasonable outside attorneys’ fees) caused by any untrue or alleged untrue statement of material fact contained in 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 not misleading, but only to the extent that such untrue statement is contained in (or not contained in, in the case of an omission) any information or affidavit so furnished in writing by such Holder expressly for use therein; provided, however, that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriters, their officers, directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company.

4.1.3 Any person or entity entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s or entity’s right to indemnification hereunder to the extent such failure has not materially 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). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement 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.

4.1.4 The indemnification provided for under this Agreement 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 or entity of such indemnified party and shall survive the transfer of securities. The Company and each Holder of Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Holder’s indemnification is unavailable for any reason.

4.1.5 If the indemnification provided under Section 4.1 hereof from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and out-of-pocket 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 out-of-pocket 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. 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; provided, however, that the liability of any Holder under this Section 4.1.5 shall be limited to the amount of the net proceeds received by such Holder in such offering giving rise to such liability. 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 4.1.1, 4.1.2 and 4.1.3 hereof, any legal or other fees, charges or out-of-pocket expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.1.5 were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in this Section 4.1.5. No person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 4.1.5 from any person or entity who was not guilty of such fraudulent misrepresentation.

Article V

5.3 Termination of Existing Lock-up. With respect to the Sponsor and the Existing Holders, the lock-up provisions in this Article V shall supersede the lock-up provisions contained in Section 7 of the Insider Letter, which provision in Section 7 of the Insider Letter shall be of no further force or effect.

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.

6.10 Additional Holders; Joinder. In addition to persons or entities who may become Holders pursuant to Section 6.2 hereof, subject to the prior written consent of the Sponsor, each Existing Holder, and each New Holder (in each case, so long as such Holder and its Affiliates hold, in the aggregate, at least 5% of the outstanding Class A ordinary shares of the Company (calculated, in the case of each New Holder as if all of its Class C ordinary shares and Retained Company Shares are exchanged for Class A ordinary shares)), the Company may make any person or entity who acquires Class A ordinary shares or rights to acquire Class A ordinary shares after the date hereof a party to this Agreement (each such person or entity, an “Additional Holder”) by obtaining an executed joinder to this Agreement from such Additional Holder in the form of Exhibit A attached hereto (a “Joinder”). Such Joinder shall specify the rights and obligations of the applicable Additional Holder under this Agreement.

Accordingly, if any particular provision of this Agreement shall be adjudicated by a court of competent jurisdiction to be invalid, prohibited or unenforceable for any reason, such provision, as to such jurisdiction, shall be ineffective, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction. Notwithstanding the foregoing, if such provision could be more narrowly drawn so as not to be invalid, prohibited or unenforceable in such jurisdiction, it shall, as to such jurisdiction, be so narrowly drawn, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction.

6.12 Entire Agreement; Restatement. This Agreement constitutes the full and entire agreement and understanding between the parties with respect to the subject matter hereof and supersedes all prior agreements and understandings relating to such subject matter. Upon the Closing, the Original RRA shall no longer be of any force or effect.
