 Exhibit 10.1 

BACKSTOP FACILITY AGREEMENT 

This Backstop Facility Agreement (this “Agreement”) is entered into as of May 10, 2021, by and among Austerlitz
Acquisition Corporation I, a Cayman Islands exempted company (the “Company”), and Cannae Holdings, Inc., a Delaware corporation (the “Purchaser”). Capitalized terms used but not defined in this Agreement shall have
the meaning ascribed to such terms in that certain Business Combination Agreement, dated as of the date hereof, by and among the Company, Wynn Interactive Ltd., an exempted company limited by shares incorporated in Bermuda (“Wave”),
and Wave Merger Sub Limited, an exempted company limited by shares incorporated in Bermuda and direct, wholly owned subsidiary of AAC (as amended, modified, supplemented or waived from time to time in accordance with its terms, the “Business
Combination Agreement”). 
 WHEREAS, in connection with the entry into the Business Combination Agreement, an allocation of up to
$690,000,000.00 of committed capital of the Purchaser has been made to subscribe for a number of AAC Class A Ordinary Shares equal to the number of AAC Class A Ordinary Shares that are properly redeemed in connection with the Special
Meeting, if any (the “AAC Shareholder Redemptions”); and 
 WHEREAS, the Purchaser is entering into this Agreement with the
Company, whereby at the BPS Closing under the Business Combination Agreement, the Purchaser will acquire AAC Class A Ordinary Shares and the Company will issue and sell such AAC Class A Ordinary Shares to the Purchaser, on a private
placement basis, solely to the extent necessary to fund AAC Shareholder Redemptions on a share for share basis and in the amount determined pursuant to Section 2(a)(i) hereof and subject to the limitations set forth herein (the
“Backstop Purchase Shares”). 
 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. Backstop Limit; Backstop Notice. 

(a) Backstop Limit. Notwithstanding anything to the contrary in this Agreement, the Purchaser shall never be required to pay a BPS
Purchase Price (as defined below) in connection with the AAC Shareholder Redemptions greater than $690,000,000.00 (the “Backstop Limit”). 

(b) Backstop Notice. On the date by which AAC Shareholder Redemptions are required to be made in accordance with the Company’s
amended and restated memorandum and articles of association, as they may be amended from time to time (the “Memorandum and Articles”) (which date is two (2) Business Days prior to the date of the Special Meeting), to the
extent the AAC Shareholder Redemptions is greater than zero (0), the Company shall (or, if the Company fails to deliver such notice, Wave shall be entitled to) deliver a written notice (the “Backstop Notice”) to the Purchaser (with
a copy to Wave) setting forth: 
  

 (i) the total number of AAC Class A Ordinary Shares subject to the AAC
Shareholder Redemptions (such number of AAC Class A Ordinary Shares, the “Subscription Amount”), 

(ii) the resulting BPS Purchase Price (as calculated in accordance with Section 2(a)(i)), which number shall in no event
be greater than the Backstop Limit, and 
 (iii) the Company’s wire instructions. 

Notwithstanding the forgoing, the “Subscription Amount” shall not include any AAC Class A Ordinary Shares subject to
the AAC Shareholder Redemptions that have been subsequently and validly withdrawn in accordance with the Company’s Memorandum and Articles and applicable Law. A Backstop Notice cannot be made, and the Company shall not be permitted to deliver a
Backstop Notice or cause the Purchaser to acquire any Backstop Purchase Shares, to the extent the Company has a Subscription Amount equal to zero (0). 

(c) For clarity, delivery of a Backstop Notice shall not be a condition to payment of the BPS Purchase Price, and any failure to deliver the
Backstop Notice as required by this Agreement shall not impair, release or otherwise modify or amend the Company’s or the Purchaser’s obligations hereunder. 

2. Sale and Purchase. 
 (a)
Backstop Purchase Shares. 
 (i) Subject to the terms and conditions hereof, the Company shall issue and sell to the
Purchaser, and the Purchaser shall purchase from the Company, a number of Backstop Purchase Shares equal to the Subscription Amount, for an aggregate purchase price equal to the product of (x) $10.00 multiplied by (y) the Subscription
Amount (such aggregate purchase price, the “BPS Purchase Price”). 
 (ii) The closing of the sale of the
Backstop Purchase Shares (the “BPS Closing”) shall be held on the Closing Date (immediately prior to the Closing and prior to the Domestication). At the BPS Closing, the Company will issue to the Purchaser the Backstop Purchase
Shares, registered in the name of the Purchaser, against (and concurrently with) the payment of the BPS Purchase Price to the Company by wire transfer of immediately available funds to the account notified to the Purchaser by the Company. 

(b) Delivery of Backstop Purchase Shares. 

(i) The Company shall register the Purchaser as the owner of the Backstop Purchase Shares purchased by the Purchaser hereunder
(individually or collectively, the “Securities”) in the register of stockholders 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 BPS Closing. 

  
 2 

 (ii) In addition to any notation or legend required under the Investor
Rights Agreement or the Registration Rights Agreement, each register and book entry for the Backstop Purchase Shares purchased by the Purchaser hereunder shall contain a notation, and each certificate (if any) evidencing the Backstop Purchase Shares
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. Subject to any restrictions in the Registration Rights Agreement or Investor
Rights Agreement, if the Backstop Purchase Shares are eligible to be sold without restriction under Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”), then at the Purchaser’s request, the Company
will, at its sole expense, cause the Company’s transfer agent to remove the legend set forth in Section 2(b)(ii) hereof. In connection therewith, if required by the Company’s transfer agent, the Company will promptly cause an opinion
of counsel to be delivered to 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 Backstop Purchase Shares 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 reasonably be expected to result in
or facilitate transfers of Backstop Purchase Shares in violation of applicable law or if the Purchaser has not provided such information, documents or certificates as the Company’s counsel reasonably requests in connection with the legal
opinion referred to above. 
 (d) Registration Rights. The Purchaser shall have registration rights to the extent set forth in the
Registration Rights Agreement that will be entered into by and among AAC, Cannae, the Sponsor and certain other parties thereto in connection with the consummation of the Transactions (the “Registration Rights”). Concurrently with
the BPS Closing, the Purchaser shall deliver to Wave and the Company a duly executed counterpart to each of the Registration Rights Agreement and the Investor Rights Agreement. 

(e) Placement Fee. As part of Purchaser’s obligation to allocate committed capital under this Agreement, the Company agrees
(contingent on Purchaser’s payment in full of the BPS Purchase Price) to pay the Purchaser a placement fee equal to $3,450,000 (the “Placement Fee”). The Placement Fee shall be paid in full at the Closing. The Company and the
Purchaser each acknowledge and agree that the Placement Fee shall constitute Transaction Expenses pursuant to the terms of the Business Combination Agreement. Purchaser shall deliver wire instructions to the Company for the Placement Fee at least
two (2) Business Days prior to the BPS Closing. 
 (f) Equitable Adjustments. If, between the date of this Agreement and the BPS
Closing, the AAC Class A Ordinary Shares shall have been changed into a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, reorganization, recapitalization, split, combination
or exchange of shares, or any similar event shall have occurred, then any number, value (including dollar value) or amount contained herein which is based upon the number of AAC Class A Ordinary Shares will be appropriately adjusted to
provide to the Purchaser the same economic effect as contemplated by this Agreement prior to such event.

 3. Representations and Warranties of the Purchaser. The Purchaser represents and
warrants to each of the Company and Wave as follows: 
 (a) Organization and Power. The Purchaser is duly organized, validly existing,
and in good standing under the laws of the jurisdiction of its formation (if the concept of “good standing” is a recognized concept in such jurisdiction) 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, the Investor Rights Agreement and the Registration Rights Agreement (collectively, the “Purchaser Agreements”). The Purchaser Agreements, when executed and delivered by the Purchaser, will constitute the valid and legally
binding obligation of the Purchaser, enforceable in accordance with their respective 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 applicable 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 Agreement 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 the Purchaser Agreements. 
 (d) Compliance with Other
Instruments. The execution, delivery and performance by the Purchaser of the Purchaser Agreements and the consummation by the Purchaser of the transactions contemplated by the Purchaser Agreements will not result in any violation or default
(i) of any provisions of its organizational documents, if applicable, (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 Law 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 Purchaser Transactions). 
 (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
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 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. 

  
 4 

 (f) Disclosure of Information. The Purchaser has had an opportunity to discuss the
Company’s existing and planned or expected business, management, financial affairs and the terms and conditions of the sale of the Securities with the Company’s management. In making its decision to purchase the Securities, the Purchaser
represents that it has relied solely upon its own independent investigation and the Company’s representations, warranties and agreements herein. The Purchaser acknowledges and agrees that it has received and has had an adequate opportunity to
review such financial and other information as it deems necessary in order to make an investment decision with respect to the Securities and made its own assessment and is satisfied concerning the relevant tax and other economic considerations
relevant to its investment in the Securities. Without limiting the generality of the foregoing, the Purchaser acknowledges that it has reviewed the documents provided to it by the Company. The Purchaser represents and agrees that it and its
professional advisor(s), if any, have had the full opportunity to ask such questions, receive such answers and obtain such information as the Purchaser and its professional advisor(s), if any, have deemed necessary to make an investment decision
with respect to the Securities. The Purchaser acknowledges that the information provided to it is preliminary and subject to change, and that any changes to such information, including, without limitation, any changes based on updated information or
changes in terms of the Transactions, shall in no way affect such its obligation to purchase the Securities hereunder. 
 (g) Restricted
Securities. The Purchaser understands that the sale of the 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 Securities are “restricted securities”
under applicable U.S. federal and state securities laws and that, pursuant to these laws, the Purchaser must hold the 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 Securities for resale, except pursuant to 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 and manner of sale, the holding period for the Securities, and 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 filed a Registration Statement on Form
S-1 to consummate its initial public offering with the SEC (the “IPO”). The Purchaser understands that the sale of the Securities hereunder 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 sale of the Securities. 

  
 5 

 (h) 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. 
 (i) Accredited
Investor. The Purchaser is an “accredited investor” as defined in Rule 501(a) of Regulation D promulgated under the Securities Act. 

(j) No General Solicitation. Neither the Purchaser, nor any of its officers, directors, employees, agents, stockholders or partners has
either directly or indirectly, including, through a broker or finder (i) to its knowledge, engaged in any general solicitation, or (ii) published any advertisement in connection with the sale of the Securities. 

(k) Residence. The principal place of business of the Purchaser is the office located at the address of the Purchaser set forth in
Section 8(a) below. 
 (l) Non-Public Information. The Purchaser acknowledges its
obligations under applicable securities laws with respect to the treatment of material non-public information relating to the Company. 

(m) Adequacy of Financing. The Purchaser has, or will have at the BPS Closing, available to it sufficient immediately available funds to
satisfy its obligations under this Agreement. 
 (n) Affiliation of Certain FINRA Members. The Purchaser is neither a person
associated nor affiliated with any underwriter of the IPO of the Company or, to its actual knowledge, any other member of the Financial Industry Regulatory Authority (“FINRA”) that participated in the IPO of the Company. 

(o) Absence of Litigation. There is no Action before or by any Governmental Authority pending or, to the knowledge of the Purchaser,
threatened against or affecting the Purchaser or any of the Purchaser’s officers or directors, whether of a civil or criminal nature or otherwise, in their capacities as such. 

(p) No Other Representations and Warranties; Non-Reliance. Except for the specific
representations and warranties contained in this Section 3 and in any certificate or agreement delivered pursuant hereto, none of the Purchaser nor any person acting on behalf of the Purchaser nor any of the Purchaser’s Affiliates (the
“Purchaser Parties”) has made, makes or shall be deemed to make any other express or implied representation or warranty with respect to the sale and purchase of the Securities, and the Purchaser Parties disclaim any such
representation or warranty. Except for the specific representations and warranties expressly made by the Company in Section 4 of this Agreement and in any certificate or agreement delivered pursuant hereto, the Purchaser Parties specifically
disclaim that they are relying upon any other representations or warranties that may have been made by the Company, any person on behalf of the Company or any of the Company’s Affiliates (collectively, the “Company Parties”).
Notwithstanding anything to the contrary in this Agreement, nothing in this Section 3(p) shall limit any claim or cause of action (or recovery in connection therewith) with respect to fraud. The Purchaser Parties separately specifically
disclaim that they are relying upon any representations or warranties that may have been made by Wave, any person on behalf of Wave or any of the Wave’s Affiliates (including Wynn Resorts, Limited).

Account”). The Purchaser agrees that (i) it has no right, title, interest or claim of any kind in or to any monies held in the Trust Account, and (ii) it shall have no right of set-off or
any right, title, interest or claim of any kind (“Claim”) to, or to any monies in, the Trust Account, in each case in connection with this Agreement, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account
that it may have in connection with this Agreement; provided, however, that nothing in this Section 5(a) shall be deemed to limit the Purchaser’s right, title, interest or claim to the Trust Account by virtue of the

stockholders, whether in the form of monetary damages or injunctive relief, the Purchaser, as applicable, shall be obligated to pay to the Company all of the Company’s legal fees and costs in connection with any such action in the event that

pledges (other than pledges in the ordinary course of business as part of prime brokerage arrangements), forward sale contracts, options, puts, calls, swaps and similar arrangements (including on a total return basis), and sales and other

 (b) Entire Agreement. This Agreement, the other Transaction Agreements and the
Confidentiality Agreement constitute the entire agreement, relating to the transactions contemplated hereby and supersede any other agreements, whether written or oral, that may have been made or entered into by or among any of the parties hereto
(and Wave) relating to the transactions contemplated hereby. No representations, warranties, covenants, understandings, agreements, oral or otherwise, relating to the transactions contemplated by this Agreement exist between the parties hereto (and
Wave) except as expressly set forth or referenced in this Agreement, the other Transaction Agreements and the Confidentiality Agreement. 

(c) No Third Party Beneficiaries. This Agreement shall be binding on, and inure solely to the benefit of, the parties hereto and their
respective successors and assigns, and nothing set forth in this Agreement is intended to, or shall be construed to confer upon or give any Person, other than the parties hereto and their respective successors and permitted assigns, any benefits,
rights or remedies under or by reason of, or any rights to enforce or cause the Company to enforce, this Agreement; provided, however, that each of the Company and the Purchaser agrees that Wave is a intended third party beneficiary of
this Agreement (including Sections 1(b), 2(d), 3, 6, 7(a) and 8) and may directly enforce each of the covenants and agreements of the Purchaser and the Company under this Agreement. 

(d) Successors. All of the terms, agreements, covenants, representations, warranties, and conditions of this Agreement are binding upon,
and inure to the benefit of and are enforceable by, the parties hereto and their respective successors and permitted assigns. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their
respective successors and permitted assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement (including Sections 8(c) and 8(q)). 

(e) Assignments. Except as otherwise specifically provided herein, no party hereto may assign either this Agreement or any of its
rights, interests, or obligations hereunder without the prior written consent of the other party and Wave; provided, however, that no consent of the Company or Wave shall be required if such assignment or delegation is to a controlled
Affiliate of Purchaser and such Affiliate executes the Registration Rights Agreement and Investor Rights Agreement in accordance with Section 2(d); provided, further, that no such assignment or delegation shall relieve the
Purchaser of its obligations hereunder (including its obligation to purchase the Backstop Purchase Shares and pay the BPS Purchase Price) and the Company and Wave shall be entitled to pursue all rights and remedies against the Purchaser subject to
the terms and conditions hereof. Any purported assignment or assumption of this Agreement or any right or obligation hereunder in contravention of this Section 8(e) shall be void ab initio. 

(f) Counterparts. This Agreement may be executed in one or more counterparts, all of which when taken together shall be considered one
and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other parties, it being understood that the parties need not sign the same counterpart. 

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

  
 13 

 (h) Governing Law. This Agreement, and any claim or cause of action hereunder based
upon, arising out of or related to this Agreement (whether based on law, in equity, in contract, in tort or any other theory) or the negotiation, execution, performance or enforcement of this Agreement, shall be governed by and construed in
accordance with the laws of the State of Delaware, without giving effect to the principles of conflicts of law thereof. 
 (i) Consent to
Jurisdiction; Waiver of Jury Trial. Each of the parties irrevocably consents to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware, provided that if subject matter jurisdiction over the matter that is the
subject of the legal proceeding is vested exclusively in the U.S. federal courts, such legal proceeding shall be heard in the U.S. District Court for the District of Delaware (together with the Court of Chancery of the State of Delaware,
“Chosen Courts”), in connection with any matter based upon or arising out of this Agreement. Each party hereby waives, and shall not assert as a defense in any legal dispute, that (i) such person is not personally subject to
the jurisdiction of the Chosen Courts for any reason, (ii) such legal proceeding may not be brought or is not maintainable in the Chosen Courts, (iii) such person’s property is exempt or immune from execution, (iv) such legal
proceeding is brought in an inconvenient forum or (v) the venue of such legal proceeding is improper. Each party hereby consents to service of process in any such proceeding in any manner permitted by Delaware law, further consents to service
of process by nationally recognized overnight courier service guaranteeing overnight delivery, or by registered or certified mail, return receipt requested, at its address specified pursuant to Section 8(a) and waives and covenants not to
assert or plead any objection which they might otherwise have to such manner of service of process. Notwithstanding the foregoing in this Section 8(i), a party may commence any action, claim, cause of action or suit in a court other than the
Chosen Courts solely for the purpose of enforcing an order or judgment issued by the Chosen Courts. TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW WHICH CANNOT BE WAIVED, EACH OF THE PARTIES WAIVES ANY RIGHT TO TRIAL BY JURY ON ANY CLAIMS OR
COUNTERCLAIMS ASSERTED IN ANY LEGAL DISPUTE RELATING TO THIS AGREEMENT WHETHER NOW EXISTING OR HEREAFTER ARISING. IF THE SUBJECT MATTER OF ANY SUCH LEGAL DISPUTE IS ONE IN WHICH THE WAIVER OF JURY TRIAL IS PROHIBITED, NO PARTY SHALL ASSERT IN SUCH
LEGAL DISPUTE A NONCOMPULSORY COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT. FURTHERMORE, NO PARTY SHALL SEEK TO CONSOLIDATE ANY SUCH LEGAL DISPUTE WITH A SEPARATE ACTION OR OTHER LEGAL PROCEEDING IN WHICH A JURY TRIAL CANNOT BE WAIVED.

 (j) Modifications and Amendments. This Agreement may not be amended, modified, supplemented or waived, in whole or in part, except
by an instrument in writing, signed by the party against whom enforcement of such amendment, modification, supplement or waiver is sought; provided, that the prior written consent of Wave shall be required for any amendments, modifications,
waivers or supplements (which shall include amendments which create additional conditionality, changes to the economics or delay the timing of any Backstop Notice). 

(k) Waiver of Damages. Notwithstanding anything to the contrary contained herein, in no event shall any party be liable for
consequential, special, exemplary or punitive damages in connection with this Agreement; provided, however, that in connection with any breach of Section 2(a) by the Purchaser, Wave (on behalf of itself and Wynn Resorts, Limited)
will be entitled to recover all forms of damages (other than punitive damages), including for loss of business reputation, opportunity costs, time value of money and diminution of value, whether such damages are direct, indirect, consequential,
special, exemplary or otherwise. 

  
 14 

 (l) Severability. If any provision of this Agreement shall be invalid, illegal or
unenforceable, the validity, legality or enforceability of the remaining provisions of this Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect. 

(m) Expenses. Except as otherwise expressly stated herein, the Company will be responsible for all 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,
transfer agents, stamp taxes and all of The Depository Trust Company’s fees associated with the issuance and resale of the Securities and the securities issuable upon conversion or exercise of the Securities. 

(n) Construction. The parties (and Wave) hereto have participated jointly in 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 Wave) and no presumption or burden of proof will arise favoring or disfavoring any party hereto (or Wave)
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. 
 (o) 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. The prior written consent of Wave shall be required for any waiver by the Company or the Purchaser of any any default, misrepresentation, or breach of warranty or covenant hereunder. 

(p) Confidentiality. Except as may be required by law, regulation or applicable stock exchange listing requirements, or upon the request
of a Governmental Authority, 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. 

  
 15 

 (q) Specific Performance; Enforcement. The Purchaser agrees that irreparable damage
for which monetary damages, even if available, would not be an adequate remedy, would occur to each of the Company and Wave in the event that the Purchaser does not perform its obligations under the provisions of this Agreement in accordance with
its specified terms or otherwise breach such provisions. The Purchaser acknowledges and agrees that (i) each of Wave and the Company shall be entitled to an injunction, specific performance, or other equitable relief, to prevent breaches of
this Agreement and to enforce specifically the terms and provisions hereof and thereof, without proof of damages, this being in addition to any other remedy to which they are entitled under this Agreement, and (ii) the right of specific
enforcement is an integral part of the transactions contemplated by this Agreement and without that right, Wave and the Company would not have entered into the Transaction Agreements (including this Agreement). The Purchaser agrees that it will not
oppose the granting of specific performance and other equitable relief on the basis that Wave or the Company have an adequate remedy at Law or that an award of specific performance is not an appropriate remedy for any reason at Law or equity. The
Purchaser acknowledges and agrees that Wave or the Company, in seeking an injunction to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 8(q), shall not be
required to provide any bond or other security in connection with any such injunction. This Agreement may be enforced only by the Company, Wave and the Purchaser, and (other than Wave) none of the Company’s direct or indirect creditors nor any
other person that is not a party to this Agreement shall have any right to enforce this Agreement or to cause the Company to enforce this Agreement.

	Re:	 Sponsor Agreement 

Ladies and Gentlemen: 
 This letter (this
“Sponsor Agreement”) is being delivered to you in accordance with that certain Business Combination Agreement (the “Business Combination Agreement”), dated as of the date hereof, by and among
Austerlitz Acquisition Corporation I, a Cayman Islands exempted company (“AAC”), Wynn Interactive Ltd., an exempted company limited by shares incorporated in Bermuda (the “Company”), and the other
party thereto, and hereby amends and restates in its entirety (a) that certain letter, dated March 2, 2021, from Austerlitz Acquisition Sponsor, LP I, a Cayman Islands exempted limited partnership (the “Sponsor”) to
AAC (the “Prior Sponsor Letter Agreement”) and (b) that certain letter, dated March 2, 2021 from each of the persons undersigned thereto to AAC (the “Prior Insider Letter
Agreement” and, together with the Prior Sponsor Letter Agreement, the “Prior Letter Agreements”). Certain capitalized terms used herein are defined in Paragraph 11. Capitalized terms used but not defined
herein shall have the respective meanings given to them in the Business Combination Agreement. 
 On or prior to the date hereof, AAC
obtained an equity commitment in the amount of up to $690,000,000 from Cannae Holdings, Inc. (“Cannae”, together with the Insiders, and the Sponsor, the “Sponsor Persons”) pursuant to the terms of that
certain Backstop Facility Agreement by and between Cannae and AAC (the “Cannae Backstop Agreement”), which provides for a subscription by Cannae to subscribe to purchase a number of AAC Class A Ordinary Shares equal to
the number of AAC Class A Ordinary Shares, if any, that are properly redeemed in connection with the Special Meeting for a purchase price of $10.00 per share (such subscriptions, the “Cannae Subscription”). 

The Sponsor and certain of the Insiders are currently, and as of immediately prior to the Closing will be, the record owners of all of the
outstanding AAC Class B Ordinary Shares (the “Founder Shares”), AAC Class C Ordinary Shares (the “Alignment Shares”), and Founder AAC Warrants, with each such Person’s ownership detailed
on Schedule A hereto. 
 As described further in Paragraph 25, Schedule A will be updated from time to time to reflect any
Sponsor Person ownership changes following the date hereof. 
 In order to induce AAC and the Company to enter into the Business Combination
Agreement and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, each Sponsor Person hereby agrees, severally and not jointly, with AAC and the Company as follows: 

1. Voting Obligations. During the period beginning on the date hereof and ending on the earliest to occur of (x) the Effective Time, and
(y) such date and time as the Business Combination Agreement shall have been terminated validly in accordance with its terms (such period, the “Interim Period”), each Sponsor Person, in its capacity as a holder of Covered
Shares, agrees irrevocably and unconditionally that, at the 

 
Special Meeting, at any other meeting of the shareholders of AAC (whether annual or special and whether or not an adjourned or postponed meeting, however called and including any adjournment or
postponement thereof), in connection with any written consent of shareholders of AAC and in connection with any similar vote or consent of the holders of Founder AAC Warrants, in their capacities as such, such Sponsor Person shall, and shall cause
any other holder of record of any of such Sponsor Person’s Covered Shares to: 
 (a) when such meeting is held, appear at such meeting
or otherwise cause the Sponsor Person’s Covered Shares to be counted as present thereat for the purpose of establishing a quorum; 
 (b)
vote (or duly and promptly execute and deliver an action by written consent), or cause to be voted at such meeting (or cause such consent to be duly and promptly executed and delivered with respect to), all of such Sponsor Person’s Covered
Shares owned as of the record date for determining holders entitled to vote at such meeting (or the record date for determining holders entitled to provide consent) in favor of the AAC Shareholder Matters and any other matters necessary or advisable
for consummation of the Transactions (including the Merger); and 
 (c) vote (or duly and promptly execute and deliver an action by written
consent), or cause to be voted at such meeting (or cause such consent to be duly and promptly executed and delivered with respect to), all of such Sponsor Person’s Covered Shares against any Business Combination Proposal (as defined below)
other than a Business Combination Proposal with the Company, its equityholders and their respective Affiliates and Representatives, and any other action that is intended, or would reasonably be expected, to impede, interfere with or delay or
postpone the consummation of, or otherwise adversely affect, any of the Transactions or result in a breach of any representation, warranty, covenant or other obligation or agreement of any AAC Party under the Business Combination Agreement or result
in a breach of any representation, warranty, covenant or other obligation or agreement of such Sponsor Person under this Sponsor Agreement. 

The obligations of the Sponsor Persons in this Paragraph 1 shall apply whether or not the board of directors of AAC (or, following the
Transactions, the Company) or other governing body or any committee, subcommittee or subgroup thereof recommends the AAC Shareholder Matters or any other matters necessary or advisable for consummation of the Transactions and whether or not such
board or other governing body, committee, subcommittee or subgroup thereof changes, withdraws, withholds, qualifies or modifies, or publicly proposes to change, withdraw, withhold, qualify or modify, the AAC Board Recommendation. 

2. Exclusivity. During the Interim Period, each Sponsor Person shall not take, nor shall it permit any of its Affiliates or any of its or their
respective Representatives to take, whether directly or indirectly, any action to (i) solicit, initiate, continue or engage in discussions or negotiations with, or enter into any agreement with, or encourage, respond, provide information to or
commence due diligence with respect to, any Person (other than the Company, its equityholders and/or any of their Affiliates or Representatives) concerning, relating to or which is intended or is reasonably likely to give rise to or result in, any
offer, inquiry, proposal or indication of interest, written or oral relating to any Business Combination involving AAC (a “Business Combination Proposal”) or (ii) approve, endorse or recommend, or make any public
statement approving, endorsing or recommending, any Business Combination Proposal, in the case of each of clauses (i) and (ii), other than a Business Combination Proposal with the Company, its equityholders and their respective Affiliates and
Representatives. Each Sponsor Person shall, and shall cause its Affiliates and Representatives to, immediately cease any and all existing discussions or negotiations with any Person conducted prior to the date hereof with respect to, or which is
reasonably likely to give rise to or result in, a Business Combination Proposal, other than with the Company, its equityholders or their respective controlled Affiliates. 

  
 2 

 3. Waiver of Certain Rights. Each Sponsor Person hereby irrevocably and unconditionally agrees: 

(a) not to (i) demand that AAC redeem its or their Covered Shares in connection with the Transactions or (ii) otherwise participate
in any such redemption by tendering or submitting any of its Covered Shares for redemption; and 
 (b) not to commence or participate in, and
to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against AAC, the Company, any Affiliate of AAC or the Company or any designee of a Sponsor Person or the Company acting in
its capacity as director, officer or manager or in any similar capacity or any of their respective successors and assigns relating to the negotiation, execution or delivery of this Sponsor Agreement, the Business Combination Agreement or the
consummation of the Transactions. 
 4. Reasonable Best Efforts; Regulatory Undertakings. 

(a) During the Interim Period, each Sponsor Person shall (i) use reasonable best efforts to take, or cause to be taken, all actions to do,
or cause to be done, all things reasonably necessary, proper or advisable under applicable Laws to consummate the Transactions on the terms and subject to the conditions set forth in the Business Combination Agreement and (ii) not take any
action that would reasonably be expected to prevent or delay the satisfaction of any of the conditions to the Transactions set forth in Article X of the Business Combination Agreement. 

(b) Without limiting the generality of the foregoing, each Sponsor Person shall use reasonable best efforts to provide or cause to be provided
(including, with respect to filings pursuant to the HSR Act, by its “Ultimate Parent Entities”, as that term is defined in the HSR Act) as promptly as reasonably practicable and advisable to any Governmental Authority information and
documents relating to such party as requested by such Governmental Authority or necessary, proper or advisable to permit consummation of the Transactions, including filing any notification and report form and related material required under the HSR
Act, any necessary or appropriate filings pursuant to applicable Gaming Laws and any other filing or notice that may be required with any other Governmental Authority as promptly as reasonably practicable and advisable after the date hereof and
thereafter to respond as promptly as reasonably practicable and advisable to any request for additional information or documentary material relating to such party that may be made. Each Sponsor Person shall supply as promptly as practicable (and
shall respond no later than ten (10) Business Days following any request) any additional information and documentary material relating to such Sponsor Person that may be requested by any Governmental Authority, and each Sponsor Person shall
(A) provide, or cause to be provided, as promptly as practicable, all agreements, documents, instruments, affidavits, statements or information (including, for the avoidance of doubt, nonpublic or other confidential financial or sensitive
personally identifiable information as well as personal information of senior management, directors or control persons) that may be required or requested by any Governmental Authority relating to (i) such Sponsor Person (including any of its
respective directors, officers, employees, partners, members, shareholders or control persons) and (ii) such Sponsor Person’s structure, ownership, businesses, operations, regulatory and legal compliance, assets, liabilities, financing,
financial condition or results of operations, or any of its or their directors, officers, employees, partners, members, shareholders or Affiliates, (B) make individuals with appropriate seniority and expertise available to participate in any
discussions or hearings and (C) prepare and file any applications, notices, registrations and requests as may be required or advisable to be filed with any Governmental Authority. 

  
 3 

 (c) Each Sponsor Person appointed or designated, or proposed to be appointed or designated,
to the board of directors of the Company or any Subsidiary, including pursuant to the terms of Section 9.09 of the Business Combination Agreement, shall use reasonable best efforts to comply and cooperate with and satisfy all requests and
requirements made by any Governmental Authority in connection with any such appointment, designation or proposed service, including by furnishing all requested information, providing reasonable assistance in connection with the preparation of any
required applications, notices and registrations and requests and otherwise facilitating access to and being available with respect to any discussions or hearings. Each Sponsor Person further acknowledges and agrees that, in the event an individual
to designated as the Initial Sponsor Director (as defined in the Investor Rights Agreement) in accordance with Section 2.1(a) of the Investors Rights Agreement does not satisfy any requirement of a Governmental Authority to serve as a director,
the Sponsor Person shall withdraw such individual and designate a replacement director in lieu of such person subject to terms and conditions of the AAC Bye-laws and the Investors Rights Agreement. 

(d) Subject to paragraph 4(f), if any objections are asserted with respect to the Transactions under any applicable Law or if any Action is
instituted by any Governmental Authority or any private party challenging any of the Transactions as violative of any applicable Law, each Sponsor Person shall, and shall cause its Affiliates to, cooperate with the Company in good faith and each
Sponsor Person shall, and shall cause its Affiliates to, use their reasonable best efforts to: (i) oppose or defend against any action to prevent or enjoin consummation of Transactions; and (ii) take such action as reasonably necessary to
overturn any regulatory action by any Governmental Authority to prevent or enjoin consummation of this Transactions, including by defending any Action brought by any Governmental Authority in order to avoid entry of, or to have vacated, overturned
or terminated, including by appeal if necessary, in order to resolve any such objections or challenge as such Governmental Authority or private party may have to any of the Transactions under such applicable Law so as to permit the consummation of
the Transactions in their entity; provided, however, that any decision by each Sponsor Person or its Affiliates to litigate in connection with such matters must be agreed upon by AAC and the Company. 

(e) In addition to, and without prejudice to, the foregoing in this paragraph 4, each of Cannae and the Sponsor shall, and shall cause its
controlled Affiliates to, take any and all actions necessary to obtain, without the imposition of any Burdensome Condition, any authorization, consent or approval of a Governmental Authority (including in connection with any Governmental Filings and
obtaining all Requisite Gaming Approvals) necessary or advisable so as to enable the consummation of the Transactions to occur as expeditiously as possible (and in any event, no later than the Termination Date) and to resolve, avoid or eliminate any
impediments or objections, if any, that may be asserted with respect to the Transactions under any Law, or to otherwise oppose, avoid the entry of, or to effect the dissolution of, any order, decree, judgment, preliminary or permanent injunction
that would otherwise have the effect of preventing, prohibiting, restricting, or delaying the consummation of the Transactions, including: (i) proposing, negotiating, committing to and effecting, by consent decree, hold separate order or
otherwise, the sale, divestiture, licensing or disposition of, or holding separate of, businesses, product lines, rights or assets of Cannae or the Sponsor, as applicable, or any of their respective controlled Affiliates and any interest therein
(including entering into customary ancillary agreements relating to any such sale, divestiture, licensing or disposition of such businesses, product lines, rights or assets); and (ii) taking or committing to take actions that after the Closing
Date would limit the Cannae or Sponsor’s freedom of action with respect to, or its ability to retain or control, one or more of the businesses, product lines, rights (including, for clarity, its right to appoint a director pursuant to the
Investor Rights Agreement) or assets (including, for clarity, any shares or other equity interests in AAC) of Cannae or the Sponsor, as applicable, or any of their respective controlled Affiliates or interest therein, in each case as may be required
in order to enable the consummation of the Transactions to occur as expeditiously as possible (and in any event no later than the Termination Date). 

  
 4 

 (f) Without limiting each Sponsor Person’s general efforts obligations set forth in
this paragraph 4, solely with respect to Gaming Approvals, it is agreed that the Company shall make all strategic decisions and lead all discussions, negotiations and other proceedings, and coordinate all activities with respect to any requests that
may be made by, or any actions or nonactions, approvals consents, waivers, exemptions and approvals that may be sought by or from, any Gaming Authority, including determining the strategy for contesting, litigating or otherwise responding to
objections to, or Actions challenging, the consummation of the Transactions; provided, that the Company shall consult in good faith with the Sponsor regarding any such decisions and activities. 

(g) From the date of this Agreement until Closing, no Sponsor Person shall acquire or agree to acquire, by merging with or into or
consolidating with, or by purchasing a substantial portion of the assets of or any equity in, or by any other manner, any assets or Person, or take any other action, if the execution and delivery of a definitive agreement relating to, or the
consummation of, such acquisition, or the taking of any other action, would reasonably be expected to, in any material respect (individually or in the aggregate), (i) impose any delay in obtaining, or increase the risk of not obtaining, without the
imposition of any Burdensome Condition, consents of a Governmental Authority necessary to consummate the Transactions or the expiration or termination of any applicable waiting period, (ii) increase the risk of a Governmental Authority seeking
or entering a Governmental Order prohibiting the consummation of the Purchaser Transactions, (iii) increase the risk of not being able to remove any such Governmental Order on appeal or otherwise, or (iv) otherwise prevent or delay the
consummation of the Transactions. 
 5. Transfer Restrictions.

Period Transfers of Covered Shares that are held by any Sponsor Person or any of its Permitted Transferees (as defined below) that have entered into a written agreement contemplated by the proviso in this subsection are permitted, in accordance with
applicable Law (including applicable securities Laws), (i) to the Sponsor Person’s officers or directors, any Affiliates or family members of such Sponsor Person’s officers or directors, to AAC, the Sponsor or Cannae, any respective
then-current directors, officers, members or partners of AAC, the Sponsor or Cannae or their respective Affiliates, any Affiliates of AAC, the Sponsor or Cannae, 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 the individual’s immediate family, an Affiliate of such Person or to a charitable organization; (iii) in the case of an individual,

subject to the obligations, in this Sponsor Agreement (and the Investor Rights Agreement). 
 (b) Post-Closing: Covered Shares. For
the period beginning on the Closing Date until the earlier of (i) one (1) year thereafter, or (ii) if the VWAP of the AAC Class A Ordinary Shares equals or exceeds $12.00 per share (as adjusted for share splits, share capitalizations,
reorganizations, recapitalizations and the like) for any twenty (20) Trading Days within a period of thirty (30) consecutive Trading days commencing 150 days after the Closing Date (such applicable period, the “Lock-Up Period”), each Sponsor Person shall not, and shall cause any other holder of record of any of such Sponsor Person’s Covered Shares not to, Transfer any of such Sponsor Person’s Covered
Shares, other than in connection with a Permitted Transfer. Following the expiration of the Lock-Up Period, each of Sponsor and Cannae (and their Permitted Transferees and transferees that have entered into a
written agreement contemplated by the definition of 

  
 5 

 
Permitted Transfer) (i) may not sell, during any individual trading day, an amount equal to more than 10% of the number of AAC Class A Ordinary Shares beneficially owned by it on the
immediately preceding Trading Day and (ii) shall structure execution of the sale of its AAC Class A Ordinary Shares in a manner that would not reasonably be expected to have a material and adverse impact on the trading price of the AAC
Class A Ordinary Shares. 
 (c) Any Transfer in violation of the provisions of this Paragraph 5 shall be null and void ab initio
and of no force or effect. 
 6. Exchange of Founder and Alignment Shares; Forfeited Founder and Alignment Shares; Waiver of Anti-Dilution Provision.

 (a) Forfeited Founder and Alignment Shares. Each Sponsor Person that holds Founder Shares and Alignment Shares, along with each of

(i) Immediately prior to the Closing, the applicable Sponsor Persons shall, in the aggregate and based on the percentages set forth on
Schedule A hereto, forfeit and surrender to AAC an amount equal to the Forfeited Founder Shares (as defined below) for no consideration. Following such forfeiture, the Forfeited Founder Shares shall be cancelled, no longer outstanding and
become void and of no further effect. “Forfeited Founder Shares” means a number of AAC Class B Ordinary Shares equal to 3,696,429 minus a number equal to the nearest whole number (rounded up or down, as

become void and of no further effect. “Forfeited Alignment Shares” means a number of AAC Class C Ordinary Shares equal to 3,696,429 minus a number equal to the nearest whole number (rounded up or down, as
applicable) obtained by multiplying (x) the number of AAC Class A Ordinary Shares purchased by Cannae pursuant to the Cannae Backstop Agreement divided by sixty-nine million (69,000,000), by (y) 3,696,429. 

(iii) At the Closing, in the event that the AAC Transaction Expenses exceed $34,150,000 (the “AAC Expense Cap” and such

AAC an amount equal to the Forfeited Expense Shares (as defined below) for no consideration. Following such forfeiture, the Forfeited Expense Shares shall be cancelled, no longer outstanding and become void and of no further effect.
