 Austerlitz Acquisition
Corporation I 
 1701 Village Center Circle 
 Las Vegas, NV

 Re:    Initial Public Offering 

Ladies and Gentlemen: 
 This letter (the “Letter
Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by and among Austerlitz Acquisition Corporation
I, a Cayman Islands exempted company (the “Company”) and Credit Suisse Securities (USA) LLC, J.P. Morgan Securities LLC and BofA Securities, Inc., as representatives (the “Representatives”) of the
several underwriters listed on Schedule I thereto (the “Underwriters”), relating to an underwritten initial public offering (the “IPO”) of the Company’s units (the
“Units”), each unit comprised of one Class A ordinary share of the Company, par value $0.0001 per share (the “Class A Ordinary Shares”), and one-fourth of one redeemable warrant, each whole warrant exercisable for one Class A Ordinary Share (each, a “Warrant”). Certain capitalized terms used herein are defined in
paragraph 10 hereof. 
 In order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the IPO, and in
recognition of the benefit that such IPO will confer upon the undersigned as a shareholder of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned hereby agrees
with the Company as follows: 
 1.    If the Company solicits approval of its shareholders of a Business Combination, the undersigned
will vote all shares beneficially owned by the undersigned, whether acquired before, in or after the IPO, in favor of such Business Combination. 

2.    In the event that the Company does not complete a Business Combination within the time period set forth in the Company’s
amended and restated memorandum and articles of association, as the same may be further amended from time to time (the “Charter”), the undersigned will, as promptly as possible, take all necessary actions to cause the Company
to (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible, but not more than 10 business days thereafter, redeem the IPO Shares, at a per-share price,
payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the Trust Account not previously released to the Company to pay its tax obligations, if any (less up to $100,000 of such net interest
to pay dissolution expenses), divided by the number of then outstanding IPO Shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if
any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors, dissolve and liquidate, subject in the cases of
clauses (ii) and (iii) to the Company’s obligations under Cayman Islands law to provide for claims of creditors and other requirements of applicable law. The undersigned 

 
hereby waives any and all right, title, interest or claim of any kind in or to any distribution of the Trust Account and any remaining net assets of the Company as a result of such liquidation
with respect to the Founder Shares or Alignment Shares owned by the undersigned. However, if the undersigned has acquired IPO Shares in or after the IPO, the undersigned will be entitled to liquidating distributions from the Trust Account with
respect to such IPO Shares in the event that the Company does not complete a Business Combination within the time period set forth in the Charter. The undersigned acknowledges and agrees that there will be no distribution from the Trust Account with
respect to any Warrants, all rights of which will terminate on the Company’s liquidation. 
 3.    The undersigned acknowledges and
agrees that prior to entering into a definitive agreement for a Business Combination with a target business that is affiliated with the undersigned or any other Insiders of the Company or their affiliates, such transaction must be approved by a
majority of the Company’s disinterested independent directors and the Company must obtain an opinion from an independent investment banking firm, or an independent accounting firm that such Business Combination is fair to the Company’s
unaffiliated shareholders from a financial point of view. 
 4.    There will be no restrictions on payments made to the undersigned,
including, but not limited to, the payments set forth in the Registration Statement adjacent to the caption “Prospectus Summary—The Offering—Payments to insiders.” However, prior to the completion of the Business Combination, the
Company shall not make any payments to the undersigned from the funds in the Trust Account. 
 5.    (a) The undersigned agrees not to
transfer, assign or sell (except to certain permitted transferees as described in the Registration Statement or herein) (the “Lockup”) any of its (1) Founder Shares until (a) one year after the completion of a
Business Combination, or (b) the date following the completion of the Company’s initial Business Combination on which the Company completes a liquidation, merger, share exchange or other similar transaction that results in all of the
Company’s shareholders having the right to exchange their Class A Ordinary Shares for cash, securities or other property, and (2) Alignment Shares and any Class A Ordinary Shares issued upon conversion thereof until the earlier
of: (a) their conversion into Class A Ordinary Shares; and (b) subsequent to the Company’s initial Business Combination, the date on which the Company completes a merger, share exchange, reorganization or other similar
transaction that results in both a change in control and all of the Company’s public shareholders having the right to exchange their ordinary shares for cash, securities or other property. Notwithstanding the foregoing, if the last reported
sale price of the Company’s Class A Ordinary Shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like)
for any 20 trading days within any 30-trading day period commencing at least 150 days after the completion of the Company’s initial Business Combination, the converted Class A Ordinary Shares will be
released from the Lockup. 
 (b)    Notwithstanding the provisions set forth in paragraphs 5(a) and 5(c), during the
period commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, the undersigned will not, without the prior written consent of the Representative pursuant to the Underwriting Agreement, (i) sell, offer
to sell, contract or agree to sell, hypothecate, pledge, hedge or otherwise dispose of or agree to dispose of (or enter into any transaction that is 

  
 2 

 
designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the undersigned
or any affiliate of the undersigned or any person in privity with the undersigned or any affiliate of the undersigned), directly or indirectly, including the filing (or participation in the filing) of a registration statement with the Securities and
Exchange Commission (the “SEC”) in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of
1934, as amended, (the “Exchange Act”) and the rules and regulations of the SEC promulgated thereunder with respect to, any other Units, Class A Ordinary Shares, Founder Shares, Alignment Shares or Warrants or any
securities convertible into, or exercisable, or exchangeable for, Class A Ordinary Shares owned by it, him or her, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic
consequences of ownership of any Units, Class A Ordinary Shares, Founder Shares, Alignment Shares, Warrants or any securities convertible into, or exercisable, or exchangeable for, Class A Ordinary Shares owned by it, him or her, whether
any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction, including the filing of a registration statement, specified in clause (i) or
(ii). The provisions of this paragraph will not apply (i) to the transfer of Founder Shares or Alignment Shares to any independent director appointed or elected to the Company’s board of directors before or after the IPO or (ii) if
the release or waiver is effected solely to permit a transfer not for consideration and, in each case the transferee has agreed in writing to be bound by the same terms described in this Letter Agreement to the extent and for the duration that such
terms remain in effect at the time of the transfer. 
 (c)    The undersigned agrees that until the Company completes an
initial Business Combination, the undersigned’s Private Placement Warrants will be subject to the transfer restrictions described in the Private Placement Warrants Purchase Agreement relating to the undersigned’s Private Placement
Warrants. 
 (d)    Notwithstanding the provisions set forth in paragraphs 5(a) and (c), transfers, assignments and
sales by the undersigned of the Founder Shares, Alignment Shares, Private Placement Warrants and Class A Ordinary Shares issued or issuable upon the exercise of the Private Placement Warrants or conversion of the Founder Shares or Alignment
Shares are permitted (i) to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors, to Austerlitz Acquisition Sponsor, LP I, a Cayman Islands exempted limited partnership
(the “Sponsor”), any members or partners of the Sponsor or its affiliates, any affiliates of the Sponsor, or any employees of such affiliates; (ii) in the case of an individual, by gift to a member of the individual’s immediate
family or to a trust, the beneficiary of which is a member of one of the individual’s immediate family, an affiliate of such person or to a charitable organization; (iii) in the case of an individual, by virtue of laws of descent and
distribution upon death of the individual; (iv) in the case of an individual, pursuant to a qualified domestic relations order; (v) by private sales or transfers made in connection with the completion of the Business Combination at prices
no greater than the price at which the Founder Shares, Alignment Shares, Private Placement Warrants or Class A Ordinary Shares, as applicable, were originally purchased; (vi) by virtue of the Sponsor’s organizational documents upon
liquidation or dissolution of the Sponsor; (vii) to the Company for no value for cancellation in connection with the completion of the Business Combination; (viii) in the event of the Company’s liquidation prior to the completion of a
Business Combination; or (ix) in the event of completion of a liquidation, 

  
 3 

 
merger, share exchange or other similar transaction which results in all of the Company’s shareholders having the right to exchange their Class A Ordinary Shares for cash, securities or
other property subsequent to the completion of a Business Combination; provided, however, that in the case of clauses (i) through (vi) these permitted transferees must enter into a written agreement agreeing to be bound by the
restrictions herein. For the avoidance of doubt, the transfers of Founder Shares, Alignment Shares, Private Placement Warrants and Class A Ordinary Shares issued or issuable upon the exercise of the Private Placement Warrants or conversion of
the Founder Shares or Alignment Shares shall be permitted regardless of whether a filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made with respect to such transfers. 

(e)    The undersigned acknowledges and agrees that if, in order to complete any Business Combination, the holders of
Founder Shares, Alignment Shares or Private Placement Warrants are required to contribute back to the capital of the Company a portion of any such securities to be cancelled by the Company or transfer any such securities to third parties, the
undersigned will contribute back to the capital of the Company or transfer to such third parties, at no cost, a proportionate number of Founder Shares, Alignment Shares or Private Placement Warrants, as applicable, pro rata with the other holders of
Founder Shares, Alignment Shares or Private Placement Warrants, as applicable. 
 6.    (a) In order to minimize potential conflicts of
interest that may arise from multiple corporate affiliations, and subject to any existing or future fiduciary or contractual obligations the undersigned might have, the undersigned hereby agrees that until the earliest of the Company’s initial
Business Combination or liquidation, the undersigned shall present to the Company for its consideration, prior to presentation to any other entity, any target business that has a fair market value of at least 80% of the assets held in the Trust
Account (excluding the amount of deferred underwriting discounts held in trust and taxes payable on the interest earned on the trust account); provided that such target business is expressly presented to the undersigned solely in his or her capacity
as a director or officer of the Company and is an opportunity that the Company is able to complete on a reasonable basis. 

(b)    The undersigned hereby agrees and acknowledges that (i) each of the Underwriter and the Company would be
irreparably injured in the event of a breach of the obligations under paragraph 6(a) above, (ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching party shall
be entitled to injunctive relief, in addition to any other remedy that such party may have in law or in equity, in the event of such breach. 

7.    The undersigned agrees to be a director or officer of the Company, as applicable, until the earlier of the completion by the Company
of an initial Business Combination, the liquidation of the Company, or his or her removal, death or incapacity. In the event of the removal or resignation of the undersigned as a director or officer (as applicable), the undersigned agrees that he or
she will not, prior to the completion of the Business Combination, without the prior express written consent of the Company, (i) use for the benefit of the undersigned or to the detriment of the Company or (ii) disclose to any third party
(unless required by law or governmental authority), any information regarding a potential target of the Company that is not generally known by persons outside of the Company, the Sponsor or their respective affiliates. The undersigned’s
biographical information previously furnished to the Company and the Representative is true and accurate in 

  
 4 

 
all material respects, does not omit any material information with respect to the undersigned’s background and contains all of the information required to be disclosed pursuant to Item 401
of Regulation S-K, promulgated under the Securities Act of 1933, as amended. The undersigned’s FINRA Questionnaire previously furnished to the Company and the Representative is true and accurate in all
material respects. The undersigned represents and warrants that:

in, any legal action for, any injunction, cease-and-desist order or order or stipulation to desist or refrain from any act or practice relating to the offering of
securities in any jurisdiction; 
 (b)    He or she has never been convicted of or pleaded guilty to any crime
(i) involving any fraud or (ii) relating to any financial transaction or handling of funds of another person, or (iii) pertaining to any dealings in any securities and he is not currently a defendant in any such criminal proceeding;
and 
 (c)    He or she has never been suspended or expelled from membership in any securities or commodities exchange
or association or had a securities or commodities license or registration denied, suspended or revoked. 
 8.    The undersigned has
full right and power, without violating any agreement by which he or she is bound, to enter into this Letter Agreement and to serve as a director or officer of the Company, as applicable. 

9.    The undersigned hereby waives any right to exercise redemption rights with respect to any of the Company’s ordinary shares
owned or to be owned by the undersigned, directly or indirectly, whether such shares be part of the Founder Shares, Alignment Shares or IPO Shares, and agrees not to seek redemption with respect to such shares (or sell such shares to the Company in
any tender offer) in connection with any shareholder vote to approve (x) a Business Combination or (y) an amendment to the Charter that would affect the substance or timing of the Company’s obligation to allow redemption in connection
with the Business Combination or to redeem 100% of the Class A Ordinary Shares if the Company has not completed a Business Combination within 24 months from the closing of the IPO. 

10.    The undersigned hereby agrees to not propose, or vote in favor of, an amendment to Article [●] of the Charter prior to the
completion of a Business Combination unless the Company provides public shareholders with the opportunity to redeem their Class A Ordinary Shares upon such approval in accordance with such Article [●] thereof. 

11.    This Letter Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York, without
giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. The undersigned hereby (i) agrees that any action, proceeding or claim against him arising out of or relating in
any way to this Letter Agreement shall be brought and enforced in the courts of the State of New York of the United States of America for the Southern District of New York, and irrevocably submits to such jurisdiction, which jurisdiction shall be
exclusive and (ii) waives any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum.

 12.    Each of the Sponsor and each Insider agree to return to the Company for
cancellation any Alignment Shares that it, he or she holds if such Alignment Shares have not converted into Class A Ordinary Shares nine years after the initial Business Combination.

 Exhibit 10.10 

FORWARD PURCHASE AGREEMENT 

This Forward Purchase Agreement (this “Agreement”) is entered into as of [●], 2021, by and between Austerlitz
Acquisition Corporation I, a Cayman Islands exempted limited company (the “Company”) and Cannae Holdings, Inc., a Delaware corporation (the “Purchaser”). 

WHEREAS, the Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization
or similar business combination with one or more businesses (a “Business Combination”); 
 WHEREAS, the Company has
confidentially submitted to the U.S. Securities and Exchange Commission (the “SEC”) a draft registration statement on Form S-1 (the “Registration Statement”) for its initial
public offering (“IPO”) of units (the “Public Units”) at a price of $10.00 per Public Unit, each comprised of one Class A ordinary share of the Company, par value $0.0001 per share (the
“Class A Share(s)”), and one-fourth of one redeemable warrant, where each whole redeemable warrant is exercisable to purchase one Class A Share at an exercise price of
$11.50 per share (the “Warrant(s)”). Only whole Warrants are exercisable. A holder of Warrants will not be able to exercise any fraction of a Warrant. The Company shall not issue fractional Warrants other than as part of the Public
Units. If, upon the detachment of the Warrants from the Public Units or otherwise, a holder of Warrants would be entitled to receive a fractional Warrant, the Company shall round down to the nearest whole number the number of Warrants to be issued
to such holder; 
 WHEREAS, following the closing of the IPO (the “IPO Closing”), the Company will seek to identify and
complete a Business Combination; and 
 WHEREAS, the parties wish to enter into this Agreement, pursuant to which immediately prior to the
closing of the Company’s initial Business Combination (the “Business Combination Closing”), the Company shall issue and sell, and the Purchaser shall purchase, on a private placement basis, 7,500,000 Class A Shares (the
“Forward Purchase Shares”) and 1,875,000 Warrants (the “Forward Purchase Warrants” and together with the Forward Purchase Shares, the “Forward Purchase Securities”) on the terms and conditions set
forth herein. 
 NOW, THEREFORE, in consideration of the premises, representations, warranties and the mutual covenants contained in this
Agreement, and for other good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the parties hereto agree as follows: 

1.    Sale and Purchase. 

(a)    Forward Purchase Securities. 

(i)    The Company shall issue and sell to the Purchaser, and the Purchaser shall purchase from the Company, the Forward
Purchase Shares and the Forward Purchase Warrants for an aggregate purchase price of $75,000,000 (the “FPS Purchase Price”). 

 (ii)    Each Forward Purchase Warrant will have the same terms as each
Warrant sold as part of the Public Units in the IPO (“Public Warrants”), and will be subject to the terms and conditions of the Warrant Agreement to be entered into between the Company and Continental Stock Transfer & Trust
Company, as Warrant Agent, in connection with the IPO (the “Warrant Agreement”). Each Forward Purchase Warrant will entitle the holder thereof to purchase one Class A Share at a price of $11.50 per share, subject to adjustment
as described in the Warrant Agreement, and only whole Forward Purchase Warrants will be exercisable. The Forward Purchase Warrants will become exercisable 30 days after the Business Combination Closing, and will expire five years after the Business
Combination Closing or earlier upon redemption or the liquidation of the Company, as described in the Warrant Agreement. 

(iii)    The Company shall require the Purchaser to purchase the Forward Purchase Securities by delivering notice to the
Purchaser, at least ten (10) Business Days before the funding of the FPS Purchase Price to the Escrow Account (defined below), specifying the anticipated date of the Business Combination Closing and instructions for wiring the FPS Purchase
Price to an account of a third-party escrow agent (the “Escrow Account”) which shall be the Company’s transfer agent (the “Escrow Agent”) pursuant to an escrow agreement between the Company and the Escrow Agent
(the “Escrow Agreement”). At least two (2) Business Days before the anticipated date of the Business Combination Closing specified in such notice, the Purchaser shall deliver the FPS Purchase Price in cash via wire transfer to
the account specified in such notice, to be held in escrow pending the Business Combination Closing. If the Business Combination Closing does not occur within thirty (30) days after the Purchaser delivers the FPS Purchase Price to the Escrow
Agent, the Escrow Agreement will provide that the Escrow Agent shall automatically return to the Purchaser the FPS Purchase Price, provided that the return of the FPS Purchase Price placed in escrow shall not terminate the Agreement or
otherwise relieve either party of any of its obligations hereunder. For the purposes of this Agreement, “Business Day” means any day, other than a Saturday or a Sunday, that is neither a legal holiday nor a day on which banking
institutions are generally authorized or required by law or regulation to close in the City of New York, New York. 

(iv)    The closing of the sale of the Forward Purchase Securities (the “FPS Closing”) shall be held on
the same date and immediately prior to the Business Combination Closing (such date being referred to as the “Closing Date”). At the FPS Closing, the Company will issue to the Purchaser the Forward Purchase Securities, each
registered in the name of the Purchaser, against (and concurrently with) release of the FPS Purchase Price by the Escrow Agent to the Company. 

(b)    Delivery of Forward Purchase Securities. 

(i)    The Company shall register the Purchaser as the owner of the Forward Purchase Securities purchased by the Purchaser
hereunder (individually or collectively, the “Securities”) in the register of members of the Company and with the Company’s transfer agent by book entry on or promptly after (but in no event more than two (2) Business Days
after) the date of the FPS Closing. 

  
 2 

 (ii)    Each register and book entry for the Securities shall contain a
notation, and each certificate (if any) evidencing the Securities shall be stamped or otherwise imprinted with a legend, in substantially the following form: 

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF
ANY STATE OR OTHER JURISDICTION, AND MAY NOT BE TRANSFERRED IN VIOLATION OF SUCH ACT AND LAWS.” 
 (c)    Legend
Removal. If the Securities are eligible to be sold without restriction under, and without the Company being in compliance with the current public information requirements of, Rule 144 under the Securities Act of 1933, as amended (the
“Securities Act”), then at the Purchaser’s request, the Company will cause the Company’s transfer agent to remove the legend set forth in Section 1(b)(ii). In connection therewith, if required by
the Company’s transfer agent, the Company will promptly cause an opinion of counsel to be delivered to and maintained with its transfer agent, together with any other authorizations, certificates and directions required by the transfer agent
that authorize and direct the transfer agent to transfer such Securities without any such legend; provided, however, that the Company will not be required to deliver any such opinion, authorization or certificate or direction if it
reasonably believes that removal of the legend could result in or facilitate transfers of Securities in violation of applicable law. 

(d)    Registration Rights. The Purchaser shall have registration rights with respect to the Forward Purchase
Securities as set forth on Exhibit A (the “Registration Rights”). 

2.    Representations and Warranties of the Purchaser. The Purchaser represents and warrants to the Company
as follows, as of the date hereof: 
 (a)    Organization and Power. The Purchaser is duly organized, validly
existing, and in good standing under the laws of the jurisdiction of its formation and has all requisite power and authority to carry on its business as presently conducted and as proposed to be conducted. 

(b)    Authorization. The Purchaser has full power and authority to enter into this Agreement. This Agreement, when
executed and delivered by the Purchaser, will constitute the valid and legally binding obligation of the Purchaser, enforceable in accordance with its terms, except (a) as limited by applicable bankruptcy, insolvency, reorganization,
moratorium, fraudulent conveyance and any other laws of general application affecting enforcement of creditors’ rights generally, (b) as limited by laws relating to the availability of specific performance, injunctive relief or other
equitable remedies, or (c) to the extent the indemnification provisions contained in the Registration Rights may be limited by applicable federal or state securities laws. 

(c)    Governmental Consents and Filings. No consent, approval, order or authorization of, or registration,
qualification, designation, declaration or filing with, any federal, state or local governmental authority is required on the part of the Purchaser in connection with the consummation of the transactions contemplated by this Agreement. 

  
 3 

 (d)    Compliance with Other Instruments. The execution, delivery
and performance by the Purchaser of this Agreement and the consummation by the Purchaser of the transactions contemplated by this Agreement will not result in any violation or default (i) of any provisions of its organizational documents,
(ii) of any instrument, judgment, order, writ or decree to which it is a party or by which it is bound, (iii) under any note, indenture or mortgage to which it is a party or by which it is bound, (iv) under any lease, agreement,
contract or purchase order to which it is a party or by which it is bound or (v) of any provision of federal or state statute, rule or regulation applicable to the Purchaser, in each case (other than clause (i)), which would have a material
adverse effect on the Purchaser or its ability to consummate the transactions contemplated by this Agreement. 

(e)    Purchase Entirely for Own Account. This Agreement is made with the Purchaser in reliance upon the
Purchaser’s representation to the Company, which by the Purchaser’s execution of this Agreement, the Purchaser hereby confirms, that the Forward Purchase Securities to be acquired by the Purchaser will be acquired for investment for the
Purchaser’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that the Purchaser has no present intention of selling, granting any participation in, or otherwise distributing the
same in violation of law. By executing this Agreement, the Purchaser further represents that the Purchaser does not presently have any contract, undertaking, agreement or arrangement with any Person to sell, transfer or grant participations to such
Person or to any third Person, with respect to any of the Forward Purchase Securities. For purposes of this Agreement, “Person” means an individual, a limited liability company, a partnership, a joint venture, a corporation, a
trust, an unincorporated organization, any other entity or any government or any department or agency thereof. 

(f)    Disclosure of Information. The Purchaser has had an opportunity to discuss the Company’s business,
management, financial affairs and the terms and conditions of the offering of the Forward Purchase Securities, as well as the terms of the Company’s proposed IPO, with the Company’s management. 

(g)    Restricted Securities. The Purchaser understands that the offer and sale of the Forward Purchase Securities
to the Purchaser has not been, and will not be, registered under the Securities Act, by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the
investment intent and the accuracy of the Purchaser’s representations as expressed herein. The Purchaser understands that the Forward Purchase Securities are “restricted securities” under applicable U.S. federal and state securities
laws and that, pursuant to these laws, the Purchaser must hold the Forward Purchase Securities indefinitely unless they are registered with the SEC and qualified by state authorities, or an exemption from such registration and qualification
requirements is available. The Purchaser acknowledges that the Company has no obligation to register or qualify the Forward Purchase Securities, or any Class A Shares into which the Forward Purchase Securities may be converted into or exercised
for, for resale, except for the Registration Rights. The Purchaser further acknowledges that if an exemption from registration or qualification is available, it may be conditioned on various requirements including, but not limited to, the time

  
 4 

 
and manner of sale, the holding period for the Forward Purchase Securities, and on requirements relating to the Company which are outside of the Purchaser’s control, and which the Company is
under no obligation and may not be able to satisfy. The Purchaser acknowledges that the Company confidentially submitted the Registration Statement for its proposed IPO to the SEC for review. The Purchaser understands that the offering of the
Forward Purchase Securities is not, and is not intended to be, part of the IPO, and that the Purchaser will not be able to rely on the protection of Section 11 of the Securities Act with respect to such Forward Purchase Securities. 

(h)    No Public Market. The Purchaser understands that no public market now exists for the Securities, and that
the Company has made no assurances that a public market will ever exist for the Securities. 
 (i)    High Degree of
Risk. The Purchaser understands that its agreement to purchase the Securities involves a high degree of risk which could cause the Purchaser to lose all or part of its investment. 

(j)    Accredited Investor. The Purchaser is an “accredited investor” as defined in Rule 501(a) of

first make an offer of the New Equity Securities to the Purchaser in accordance with the following provisions of this Section 4: 

(a)    Offer Notice. 

(i)    The Company shall give written notice (the “Offering Notice”) to the Purchaser stating its
bona fide intention to offer the New Equity Securities and specifying the number of New Equity Securities and the material terms and conditions, including the price, pursuant to which the Company proposes to offer the New Equity Securities.

(b)    Exercise of Right of First Offer. 

(i)    Upon receipt of the Offering Notice, the Purchaser shall have until the end of the ROFO Notice Period to offer to
purchase all (but not less than all) of the New Equity Securities, by delivering a written notice (a “ROFO Offer Notice”) to the Company stating that it offers to purchase such New Equity Securities on the terms specified in the
Offering Notice. Any ROFO Offer Notice so delivered shall be binding upon delivery and irrevocable by the Purchaser. 

(ii)    If the Purchaser does not deliver a ROFO Offer Notice during the ROFO Notice Period, the Purchaser shall be
deemed to have waived all of the Purchaser’s rights to purchase the New Equity Securities offered pursuant to the Offering Notice under this Section 4, and the Company shall thereafter be free to sell or enter into an agreement to sell the
Purchaser’s New Equity Securities to any third party without any further obligation to the Purchaser pursuant to this Section 4 within the ninety (90) day period thereafter (and with respect to an agreement to sell, consummate such
sale at any time thereafter) on terms and conditions not more favorable to the third party than those set forth in the Offering Notice. If the Company does not sell or enter into an agreement to sell the Purchaser’s New Equity Securities within
such ninety (90) day period, the rights provided hereunder shall be deemed to be revived and the New Equity Securities shall not be offered to any third party unless first re-offered to the Purchaser in

“Excluded Securities” means Class B Shares (and Class A Shares for which such Class B Shares are convertible) issued to the Sponsor prior to the IPO, Class C Shares issued to the Sponsor prior to the IPO (and

same exercise price as the Warrants (the “Private Placement Warrants”), warrants issued upon the conversion of working capital loans to the Company to be made by the Sponsor or an affiliate thereof to finance transaction costs in
connection with an intended initial Business Combination (up to $1,500,000 of which may be convertible at the option of the lender into warrants of the post-Business Combination entity having the same terms as the Private Placement Warrants at a

Closing with the Purchaser.

contained herein, prior to the IPO, the Company will not issue or agree to issue any securities (other than Forward Purchase Securities in the amounts set forth in this Agreement, Private Placement Warrants and the securities to be issued in the

 (a)    Trust Account. 

(i)    The Purchaser hereby acknowledges that it is aware that the Company will establish a trust account (the

right, title, interest or claim of any kind (“Claim”) to, or to any monies in, the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account that it may have now or in the future, except for
redemption and liquidation rights, if any, the Purchaser may have in respect of any Class A Shares held by it. In the event the Purchaser has any Claim against the Company under this Agreement, the Purchaser shall pursue such Claim solely

Class A Shares it is required to vote hereunder in favor of a Proposed Business Combination, the Purchaser hereby grants hereunder to the Company and any representative designated by the Company without further action by the Purchaser a limited
irrevocable power of attorney to effect such vote on behalf of the Purchaser, which power of attorney shall be deemed to be coupled with an interest.

 (j)    Jurisdiction. The parties (i) hereby
irrevocably and unconditionally submit to the jurisdiction of the state courts of New York and to the jurisdiction of the United States District Court for the Southern District of New York for the purpose of any suit, action or other proceeding
arising out of or based upon this Agreement, (b) agree not to commence any suit, action or other proceeding arising out of or based upon this Agreement except in state courts of New York or the United States District Court for the Southern

courts, that its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement or the subject
matter hereof may not be enforced in or by such court. 
 (k)    Waiver of Jury Trial. The parties hereto hereby
waive any right to a jury trial in connection with any litigation pursuant to this Agreement and the transactions contemplated hereby.

material economic or non-economic provision of this Agreement applicable to the Purchaser, which shall in each case also require the written consent of the Purchaser. 

(m)    Severability. The provisions of this Agreement will be deemed severable and the invalidity or
unenforceability of any provision will not affect the validity or enforceability of the other provisions hereof; provided that if any provision of this Agreement, as applied to any party hereto or to any circumstance, is adjudged by a
governmental authority, arbitrator, or mediator not to be enforceable in accordance with its terms, the parties hereto agree 

  
 15 

 
that the governmental authority, arbitrator, or mediator making such determination will have the power to modify the provision in a manner consistent with its objectives such that it is
enforceable, and/or to delete specific words or phrases, and in its reduced form, such provision will then be enforceable and will be enforced. 

(n)    Expenses. The Company will bear its own and the Purchaser’s costs and expenses incurred in connection
with the preparation, execution and performance of this Agreement and the consummation of the transactions contemplated hereby, including all fees and expenses of agents, representatives, financial advisors, legal counsel and accountants. The

negotiation and drafting of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise favoring or
disfavoring any party hereto because of the authorship of any provision of this Agreement. Any reference to any federal, state, local, or foreign law will be deemed also to refer to law as amended and all rules and regulations promulgated
thereunder, unless the context requires otherwise. The words “include,” “includes,” and “including” will be deemed to be followed by “without limitation.” Pronouns in masculine,
feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words “this Agreement,”
“herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly so limited. The
parties hereto intend that each representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect, the fact that
there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that such party
hereto is in breach of the first representation, warranty, or covenant. 
 (p)    Waiver. No waiver by any party
hereto of any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, may be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect
in any way any rights arising because of any prior or subsequent occurrence. 
 (q)    Confidentiality. Except as
may be required by law, regulation or applicable stock exchange listing requirements, unless and until the transactions contemplated hereby and the terms hereof are publicly announced or otherwise publicly disclosed by the Company, the parties
hereto shall keep confidential and shall not publicly disclose the existence or terms of this Agreement. 

(r)    Specific Performance. The Purchaser agrees that irreparable damage may occur in the event any provision of
this Agreement was not performed by the Purchaser in accordance with the terms hereof and that the Company shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or equity.

 (s)    Most Favored Nations. The Company hereby represents and
warrants that as of the date hereof, and covenants and agrees that after the date hereof, none of the agreements with any other Person for the purchase of Class A Shares or Warrants include or will include terms, rights or other benefits that
are more favorable, in any material respect, to such other Person than the terms, rights and benefits in favor of the Purchaser under this Agreement, and the Company will not amend any of the terms, rights or benefits in, or waive any material
obligation under, any of the agreements with such other Person unless, in any such case, the Purchaser has been offered in writing the opportunity to concurrently receive the benefits of all such terms, rights and benefits or waiver. The Purchaser
shall notify the Company in writing, within ten (10) days after the date it has been offered the opportunity to receive the benefit of such terms, rights, benefits or waiver, of its election to receive any such term, right, benefit or waiver so
offered.

 Exhibit A 

Registration Rights 

1.    Within thirty (30) days after the Business Combination Closing, the Company shall use reasonable best efforts
(i) to file a registration statement on Form S-3, or any similar short-form registration statement which may be available at such time, or if the Company is ineligible to use Form S-3, on Form S-1 (including any successor registration statement covering the resale of the Registrable Securities a “Resale Shelf”) of (x) the
Class A Shares and Warrants (and underlying Class A Shares) comprising the Forward Purchase Securities, (y) any other Class A Shares that may be acquired by the Purchaser after the date of this Agreement, including any time after
the Business Combination Closing, and (z) any other equity security of the Company issued or issuable with respect to the securities referred to in clauses (x) and (y) by way of a share capitalization or share split or in connection with a
combination of shares, recapitalization, merger, consolidation or reorganization (collectively, the “Registrable Securities”) pursuant to Rule 415 under the Securities Act; provided that in the event the Company files a
Resale Shelf on Form S-1, the Company shall convert the Form S-1 to a Form S-3 as soon as practicable after the Company is
eligible to use Form S-3, (ii) to cause the Resale Shelf to be declared effective under the Securities Act promptly thereafter and (iii) to maintain the effectiveness of such Resale Shelf with respect to
the Purchaser’s Registrable Securities until the earliest of (A) the date on which the Purchaser or its assignee ceases to hold Registrable Securities covered by such Resale Shelf, (B) the date all of the Purchaser’s Registrable
Securities covered by the Resale Shelf can be sold publicly without restriction or limitation (including without volume or manner of sale restrictions) under Rule 144 under the Securities Act and without the requirement to be in compliance with Rule
144(c)(1) under the Securities Act. 
 2.    In the event the Company is prohibited by applicable rule, regulation or
interpretation by the staff (“Staff”) of the Securities and Exchange Commission (“SEC”) from registering all of the Registrable Securities on the Resale Shelf or the Staff requires that the Purchaser be specifically
identified as an “underwriter” in order to permit such registration statement to become effective, and such Purchaser does not consent in writing to being so named as an underwriter in such registration statement, the number of Registrable
Securities to be registered on the Resale Shelf will be reduced on a pro rata basis among all the holders of Registrable Securities to be so included, unless otherwise required by the Staff, so that the number of Registrable Securities to be
registered is permitted by Staff and such Purchaser is not required to be named as an “underwriter”; provided, that any Registrable Securities not registered due to this paragraph 2 shall thereafter as soon as allowed by the SEC
guidance be registered to the extent the prohibition no longer is applicable. 
 3.    If at any time the Company
proposes to file a registration statement (a “Registration Statement”) on its own behalf, or on behalf of any other Persons who have registration rights (“Other Holders”), relating to an underwritten offering of
ordinary shares (a “Company Offering”), then the Company will provide the Purchaser (the “Piggyback Holder”) with notice in writing (an “Offer Notice”) at least five (5) Business Days prior to
such filing, which Offer Notice will offer to include in the Registration Statement a minimum of 1,000,000 “Registrable Securities” (as defined under the Piggyback Holder’s agreement governing registration rights) of the Piggyback
Holder (collectively “Piggyback Securities”). Within five 

  
 A-1 

 
(5) Business Days (or, in the case of an Offer Notice delivered to the Purchaser in connection with an Underwritten Shelf Takedown (as described below), within three (3) Business Days) after
receiving the Offer Notice, the Piggyback Holder may make a written request (a “Piggyback Request”) to the Company to include some or all of the Piggyback Holder’s Registrable Securities in the Registration Statement. If the
underwriter(s) for any Company Offering advise the Company that marketing factors require a limitation on the number of securities that may be included in the Company Offering, the number of securities to be so included shall be allocated as
follows: (i) first, to the Company and the Other Holders, if any; and (ii) second, to the Piggyback Holder based on the pro rata percentage of Piggyback Securities held by the Piggyback Holder and requested to be included in the Company
Offering. 
 4.    At any time during which the Company has an effective Resale Shelf with respect to the
Purchaser’s Registrable Securities, the Purchaser may make a written request (which request shall specify the intended method of disposition thereof) (a “Shelf Takedown Request”) to the Company to effect a sale, of all or a
portion of the Purchaser’s Registrable Securities that are covered by the Resale Shelf, and the Company shall use commercially reasonable efforts to file a prospectus supplement (a “Shelf Takedown Prospectus Supplement”) for
such purpose as soon as reasonably practicable following receipt of a Shelf Takedown Request. The Purchaser may request that any such sale be conducted as an underwritten public offering (an “Underwritten Shelf Takedown”). 

5.    The determination of whether any offering of Registrable Securities pursuant to the Resale Shelf or a Shelf Takedown
Prospectus Supplement will be an underwritten offering shall be made in the sole discretion of the Purchaser, after consultation with the Company, and the Purchaser shall have the right, after consultation with the Company, to determine the plan of
distribution, including the price at which the Registrable Securities are to be sold and the underwriting commissions, discounts and fees (and the Requesting Holders shall not have the right to make any determinations other than whether they wish to
include their Requesting Holder Securities in the prospectus supplement). The Purchaser shall select the investment banker or bankers and managers to administer the offering, including the lead managing underwriter (provided that such investment
banker or bankers and managers shall be reasonably satisfactory to the Company). 
 6.    In connection with any
underwritten offering, the Company shall enter into such customary agreements and take all such other actions in connection therewith (including those requested by the Purchaser) in order to facilitate the disposition of such Registrable Securities
as are reasonably necessary or required, and in such connection enter into a customary underwriting agreement that provides for customary opinions, comfort letters and officer’s certificates and other customary deliverables and make management
and its own accountants available for any due diligence sessions and make management reasonably available for a road show. 

7.    The Company shall pay all fees and expenses incident to the performance of or compliance with its obligation to
prepare, file and maintain the Resale Shelf (including the fees of its counsel and accountants). The Company shall also pay all Registration Expenses. For purposes of this paragraph 7, “Registration Expenses” shall mean the out-of-pocket expenses of a Company Offering or Underwritten Shelf Takedown, including, without limitation, the following: (i) all registration and filing fees (including
fees with respect to filings required to be 

  
 A-2 

 
made with FINRA) and any securities exchange on which the Registrable Securities are then listed; (ii) fees and expenses of compliance with securities or blue sky laws (including reasonable
fees and disbursements of counsel for the underwriters in connection with blue sky qualifications of the Registrable Securities); (iii) printing, messenger, telephone and delivery expenses; (iv) reasonable fees and disbursements of counsel for
the Company; (v) reasonable fees and disbursements of all independent registered public accountants of the Company incurred specifically in connection with such Underwritten Shelf Takedown; and (vi) reasonable fees and expenses of one
legal counsel selected by the holders of a majority of the Registrable Securities, who will represent all the selling shareholders. 

8.    The Company may suspend the use of a prospectus included in the Resale Shelf by furnishing to the Purchaser a
written notice (“Suspension Notice”) stating that in the good faith judgment of the Company, it would be either (i) prohibited by the Company’s insider trading policy (as if the Purchaser were covered by such policy) or
(ii) materially detrimental to the Company and its shareholders for such prospectus to be used at such time. The Company’s right to suspend the use of such prospectus under clause (ii) of the preceding sentence may be exercised for a
period of not more than sixty (60) days after the date of such notice to the Purchaser; provided such period may be extended for an additional thirty (30) days with the consent of a majority-in-interest of the holders of Registrable Securities covered by the Resale Shelf, which consent shall not be unreasonably withheld; provided further, that such right to suspend the use of a
prospectus shall be exercised by the Company not more than once in any twelve (12) month period. A holder of Registrable Securities shall not effect any sales of Registrable Securities pursuant to the Resale Shelf at any time after it has
received a Suspension Notice from the Company and prior to receipt of an End of Suspension Notice (as defined below). The holders may recommence effecting sales of the Registrable Securities pursuant to the Resale Shelf following further written
notice to such effect (an “End of Suspension Notice”) from the Company to the holders. The Company shall act in good faith to permit any suspension period contemplated by this paragraph to be concluded as promptly as reasonably
practicable. 
 9.    The Purchaser agrees that, except as required by applicable law, the Purchaser shall treat as
confidential the receipt of any Suspension Notice (provided that in no event shall such notice contain any material nonpublic information of the Company) hereunder and shall not disclose or use the information contained in such Suspension
Notice without the prior written consent of the Company until such time as the information contained therein is or becomes public, other than as a result of disclosure by a holder of Registrable Securities in breach of the terms of this Agreement.

 10.    The Company shall indemnify and hold harmless the Purchaser, its directors and officers, partners, members,
managers, employees, agents, and representatives of such Purchaser and each person, if any, who controls the Purchaser within the meaning of the Securities Act and the Exchange Act and any agent thereof (collectively, “Indemnified
Persons”), to the fullest extent permitted by applicable law, from and against any losses, claims, damages, liabilities, joint or several, costs (including reasonable costs of preparation and reasonable attorneys’ fees) and expenses,
judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Indemnified Person may be involved,
or is threatened to be involved, as a party or otherwise, under the Securities Act or otherwise (collectively, “Losses”), promptly 

  
 A-3 

 
as incurred, arising out of, based upon or resulting from any untrue statement or alleged untrue statement of any material fact contained in the Resale Shelf (or any amendment or supplement
thereto), the related prospectus, or any amendment or supplement thereto, or arise out of, are based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances in which they were made, not misleading; provided, however, that the Company shall not be liable in any such case or to any Indemnified Person to the extent that any such Loss arises
out of, is based upon or results from an untrue statement or alleged untrue statement or omission or alleged omission or so made in reliance upon or in conformity with information furnished by or on behalf of such Indemnified Person in writing
specifically for use in the preparation of the Resale Shelf, the related prospectus, or any amendment or supplement thereto. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such
Indemnified Person, and shall survive the transfer of such securities by the Purchaser. 
 11.    The Company’s
obligation under paragraph (1) of this Exhibit A is subject to the Purchaser’s furnishing to the Company in writing such information as the Company reasonably requests for use in connection with the Resale Shelf, the related prospectus, or
any amendment or supplement thereto. The Purchaser shall indemnify the Company, its officers, directors, managers, employees, agents and representatives, and each person who controls the Company (within the meaning of the Securities Act) against any
losses, claims, damages, liabilities and expenses resulting from any untrue statement or alleged untrue statement of material fact contained in the Resale Shelf, the related prospectus, or any amendment 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 or omission is contained in any information so furnished in writing by
such Purchaser expressly for inclusion in such document; provided that the obligation to indemnify shall be individual, not joint and several, for each Purchaser and shall be limited to the net amount of proceeds received by such Purchaser
from the sale of Registrable Securities pursuant to the Resale Shelf. 
 12.    The Company shall cooperate with the
Purchaser, to the extent the Registrable Securities become freely tradable, to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legend) representing the Registrable Securities to be offered pursuant to a
Resale Shelf and enable such certificates to be in such denominations or amounts, as the case may be, as the Purchaser may reasonably request and registered in such names as the Purchaser may request. 

13.    If requested by the Purchaser, the Company shall as soon as practicable, subject to any Suspension Notice,
(i) incorporate in a prospectus supplement or post-effective amendment such information as the Purchaser reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including, without limitation,
information with respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering; (ii) make all required
filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment; and (iii) supplement or make amendments to any Registration
Statement if reasonably requested by the Purchaser holding any Registrable Securities. 

  
 A-4 

 14.    As long as the Purchaser shall own Registrable Securities, the
Company, at all times while it shall be reporting under the Exchange Act, covenants 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 Purchaser with true and complete copies of all such filings, unless filed through the SEC’s EDGAR system. The Company further covenants that it shall
take such further action as the Purchaser may reasonably request, all to the extent required from time to time, to enable the Purchaser to sell the Class A Shares and Warrants held by the Purchaser without registration under the Securities Act
within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act, including providing any legal opinions. Upon the request of the Purchaser, the Company shall deliver to the Purchaser a written certification of a
duly authorized officer as to whether it has complied with such requirements. 
 15.    The rights, duties and
obligations of the Purchaser under this Exhibit A may be assigned or delegated by the Purchaser in conjunction with and to the extent of any permitted transfer or assignment of Registrable Securities by the Purchaser to any permitted transferee or
assignee.
