Class B ordinary shares of the Company, par value $0.0001 per share (the “Class B Ordinary Shares”), then held by Sponsor for cancellation in exchange for (i) warrants to purchase

purchase 17,000,000 shares of Ordinary Shares at an exercise price of $15.00 per share, and (iii) 50,000 Ordinary Shares, in the case of each of clauses (i), (ii) and (iii), newly issued by the Company;

WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with
the issuance, registration, transfer, exchange, redemption and exercise of the Warrants; 
 WHEREAS, the Company desires to provide for the
form and provisions of the Warrants, the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights, and immunities of the Company, the Warrant Agent and the holders of the Warrants; and 

WHEREAS, all acts and things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company and
countersigned by or on behalf of the Warrant Agent (if a physical certificate is issued), as provided herein, the valid, binding and legal obligations of the Company, and to authorize the execution and delivery of this Agreement. 

 NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties
hereto agree as follows: 
 1. Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the
Company for the Warrants, and the Warrant Agent hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this Agreement. 

2. Warrants. 
 2.1.
Form of Warrant. Each Warrant shall initially be issued in registered form only. 
 2.2. Effect of
Countersignature. If a physical certificate is issued, unless and until countersigned by the Warrant Agent pursuant to this Agreement, a certificated Warrant shall be invalid and of no effect and may not be exercised by the holder thereof. 

2.3. Registration. 

2.3.1. Warrant Register. The Warrant Agent shall maintain books (the “Warrant Register”), for the registration
of original issuance and the registration of transfer of the Warrants. Upon the initial issuance of the Warrants in book-entry form, the Warrant Agent shall issue and register the Warrants in the names of the respective holders thereof in such
denominations and otherwise in accordance with instructions delivered to the Warrant Agent by the Company. 
 If requested, the registered
holder of a Warrant shall be issued a definitive certificate in physical form evidencing such Warrants (“Definitive Warrant Certificates”) which shall be in the form annexed hereto as Exhibit A. Each
Warrant shall bear the legend set forth in Exhibit B. 
 Physical certificates, if issued, shall be signed by, or bear the facsimile
signature of, the Chairman of the Board, Chief Executive Officer, President, Chief Financial Officer, Chief Operating Officer, General Counsel, Secretary or other principal officer of the Company. In the event the person whose facsimile signature
has been placed upon any Warrant shall have ceased to serve in the capacity in which such person signed the Warrant before such Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of
issuance. 
 2.3.2. Registered Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the
Warrant Agent may deem and treat the person in whose name such Warrant is registered in the Warrant Register (the “Registered Holder”) as the absolute owner of such Warrant and of each Warrant represented thereby, for the
purpose of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. 

2.4. Fractional Warrants. The Company shall not issue fractional Warrants. 

2.5 Treatment of Merger. The Merger shall constitute the initial Business Combination for all purposes of this Agreement. From and
after completion of the Merger, all references to the Company shall be deemed to be references to the Surviving Corporation, all references to Ordinary Shares shall be deemed to be references to shares of Class A Common Stock, and all
references to the amended and restated memorandum and articles of association of the Company shall be deemed to be references to the certificate of incorporation and bylaws of the Surviving Corporation. 

3. Terms and Exercise of Warrants. 

3.1. Warrant Price. Each whole Warrant shall entitle the Registered Holder thereof, subject to the provisions of such Warrant and of
this Agreement, to purchase from the Company the number of Ordinary Shares stated therein, at the price of $15.00 per share, subject to the adjustments provided in Section 4 hereof and in the last sentence of this
Section 3.1. The term “Warrant Price” as used in this Agreement shall mean the price per share (including in cash or by payment of Warrants pursuant to a “cashless exercise,” to the extent
permitted 

 
hereunder) described in the prior sentence at which Ordinary Shares may be purchased at the time a Warrant is exercised. The Company in its sole discretion may lower the Warrant Price at any time
prior to the Expiration Date (as defined below) for a period of not less than fifteen Business Days (unless otherwise required by the Commission, any national securities exchange on which the Warrants are listed or applicable law); provided that the
Company shall provide at least five days’ prior written notice of such reduction to Registered Holders of the Warrants; and provided further, that any such reduction shall be identical among all of the Warrants. The term “Business
Day” means a day, other than a Saturday, Sunday or federal holiday on which banks in New York City are generally open for normal business. 

3.2. Duration of Warrants. A Warrant may be exercised only during the period (the “Exercise Period”)
(A) commencing on the later of: (i) the date that is thirty (30) days after the first date on which the Company completes an intended initial merger, share exchange, asset acquisition, share purchase, reorganization or similar
business combination, involving the Company and one or more businesses (a “Business Combination”), and (ii) the date that is twelve (12) months from the date of the closing of the Company’s initial public
offering, and (B) terminating at the earliest to occur of (x) 5:00 p.m., New York City time on the date that is ten (10) years after the date on which the Company completes its initial Business Combination and (y) the liquidation
of the Company in accordance with the Company’s amended and restated memorandum and articles of association, as amended from time to time, if the Company fails to complete a Business Combination (the “Expiration Date”);
provided, however, that the exercise of any Warrant shall be subject to the satisfaction of any applicable conditions, as set forth in subsection 3.3.2 below, with respect to an effective registration
statement or a valid exemption therefrom being available. Each Warrant not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease at 5:00
p.m. New York City time on the Expiration Date. The Company in its sole discretion may extend the duration of the Warrants by delaying the Expiration Date; provided that the Company shall provide at least twenty (20) days prior
written notice of any such extension to Registered Holders of the Warrants and, provided further that any such extension shall be identical in duration among all the Warrants. 

3.3. Exercise of Warrants. 

3.3.1. Payment. Subject to the provisions of the Warrant and this Agreement, a Warrant may be exercised by the Registered Holder
thereof by delivering to the Warrant Agent at its corporate trust department (i) the Definitive Warrant Certificate evidencing the Warrants to be exercised, (ii) an election to purchase (“Election to Purchase”) any
Ordinary Shares pursuant to the exercise of a Warrant, properly completed and executed by the Registered Holder on the reverse of the Definitive Warrant Certificate, and (iii) the payment in full of the Warrant Price for each Ordinary Share as
to which the Warrant is exercised and any and all applicable taxes due in connection with the exercise of the Warrant, the exchange of the Warrant for the Ordinary Shares and the issuance of such Ordinary Shares, as follows: 

(a) in lawful money of the United States, in good certified check or good bank draft payable to the order of the Warrant Agent; 

(b) with respect to any Warrant, by surrendering the Warrants for that number of Ordinary Shares equal to the quotient obtained by dividing
(x) the product of the number of Ordinary Shares underlying the Warrants, multiplied by the excess of the “Last Reported Sale Price” (as defined in this subsection 3.3.1(b)) less the Warrant
Price by (y) the Last Reported Sale Price. The “Last Reported Sale Price” shall mean the last reported sale price of the Ordinary Shares on the date prior to the date on which notice of exercise of the Warrant is sent to
the Warrant Agent; or 
 (c) as provided in Section 6.4 hereof. 

3.3.2. Issuance of Ordinary Shares on Exercise. As soon as practicable after the exercise of any Warrant and the clearance of the
funds in payment of the Warrant Price (if payment is pursuant to subsection 3.3.1(a)), the Company shall issue to the Registered Holder of such Warrant a book-entry position or certificate, as applicable, for the number of
Ordinary Shares to which he, she or it is entitled, registered in such name or names as may be directed by him, her or it on the register of members of the Company, and if such Warrant shall not have been exercised in full, a new book-entry position
or countersigned Warrant, as applicable, for the number 

 
of shares as to which such Warrant shall not have been exercised. Notwithstanding the foregoing, the Company shall not be obligated to deliver any Ordinary Shares pursuant to the exercise of a
Warrant and shall have no obligation to settle such Warrant exercise unless (i) a registration statement under the Securities Act of 1933, as amended (the “Securities Act”), with respect to the Ordinary Shares underlying
the Warrants is then effective and a prospectus relating thereto is current, subject to the Company’s satisfying its obligations under Section 6.4 or (ii) a valid exemption from registration is available. No
Warrant shall be exercisable and the Company shall not be obligated to issue Ordinary Shares upon exercise of a Warrant unless the Ordinary Shares issuable upon such Warrant exercise have been registered, qualified or deemed to be exempt from
registration or qualification under the securities laws of the state of residence of the Registered Holder of the Warrants. Subject to Section 4.6 of this Agreement, a Registered Holder of Warrants may exercise its Warrants
only for a whole number of Ordinary Shares. If, by reason of any exercise of Warrants on a “cashless basis”, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in an
Ordinary Share, the Company shall round down to the nearest whole number, the number of Ordinary Shares to be issued to such holder. For the avoidance of doubt, in no event will the Company be required to pay cash to the holder of any Warrant. 

3.3.3. Valid Issuance. All Ordinary Shares issued upon the proper exercise of a Warrant in conformity with this Agreement shall be
validly issued, fully paid and nonassessable. 
 3.3.4. Date of Issuance. Each person in whose name any book-entry position or
certificate, as applicable, for Ordinary Shares is issued and who is registered in the register of members of the Company shall for all purposes be deemed to have become the holder of record of such Ordinary Shares on the date on which the Warrant,
or book-entry position representing such Warrant, was surrendered and payment of the Warrant Price was made, irrespective of the date of delivery of such certificate in the case of a certificated Warrant, except that, if the date of such surrender
and payment is a date when the register of members of the Company or book-entry system of the Warrant Agent are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on
which the share transfer books or book-entry system are open. 
 3.3.5. Maximum Percentage. A holder of a Warrant may notify the
Company in writing in the event it elects to be subject to the provisions contained in this subsection 3.3.5; however, no holder of a Warrant shall be subject to this subsection 3.3.5 unless
he, she or it makes such election. If the election is made by a holder, the Warrant Agent shall not effect the exercise of the holder’s Warrant, and such holder shall not have the right to exercise such Warrant, to the extent that after giving
effect to such exercise, such person (together with such person’s affiliates), to the Warrant Agent’s actual knowledge, would beneficially own in excess of 9.8% (the “Maximum Percentage”) of the Ordinary Shares
outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of Ordinary Shares beneficially owned by such person and its affiliates shall include the number of Ordinary Shares issuable
upon exercise of the Warrant with respect to which the determination of such sentence is being made, but shall exclude Ordinary Shares that would be issuable upon (x) exercise of the remaining, unexercised portion of the Warrant beneficially
owned by such person and its affiliates and (y) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such person and its affiliates (including, without limitation, any
convertible notes or convertible preferred shares or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial
ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For purposes of the Warrant, in determining the number of outstanding Ordinary
Shares, the holder may rely on the number of outstanding Ordinary Shares as reflected in (1) the Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other public filing with the Commission as the case may be, (2) a more recent public announcement by the Company or
(3) any other notice by the Company or Continental Stock Transfer & Trust Company, as transfer agent (in such capacity, the “Transfer Agent”), setting forth the number of Ordinary Shares outstanding. For any
reason at any time, upon the written request of the holder of the Warrant, the Company shall, within two (2) Business Days, confirm orally and in writing to such holder the number of Ordinary Shares then outstanding. In any case, the number of
issued and outstanding Ordinary Shares shall be determined after giving effect to the conversion or exercise of equity securities of the Company by the holder and its affiliates since the date as of which such number of issued and outstanding
Ordinary Shares was reported. By written notice to the Company, the holder of a Warrant may from time to time increase or decrease the Maximum Percentage applicable to such holder to any other percentage specified in such notice; provided,
however, that any such increase shall not be effective until the sixty-first (61st) day after such notice is delivered to the Company. 

 4. Adjustments. 

4.1. Share Capitalizations. 

4.1.1. Sub-Divisions. If after the date hereof, and subject to the provisions of
Section 4.6 below, the number of issued and outstanding Ordinary Shares is increased by a capitalization or share dividend of Ordinary Shares, or by a sub-division of Ordinary Shares
or other similar event, then, on the effective date of such share capitalization, sub-division or similar event, the number of Ordinary Shares issuable on exercise of each Warrant shall be increased in
proportion to such increase in the issued and outstanding Ordinary Shares. A rights offering made to all or substantially all of the holders of Ordinary Shares entitling holders to purchase Ordinary Shares at a price less than the “Historical
Fair Market Value” (as defined below) shall be deemed a capitalization of a number of Ordinary Shares equal to the product of (i) the number of Ordinary Shares actually sold in such rights offering (or issuable under any other equity
securities sold in such rights offering that are convertible into or exercisable for the Ordinary Shares) multiplied by (ii) one (1) minus the quotient of (x) the price per Ordinary Share paid in such rights offering divided by
(y) the Historical Fair Market Value. For purposes of this subsection 4.1.1, (i) if the rights offering is for securities convertible into or exercisable for Ordinary Shares, in determining the price payable for
Ordinary Shares, there shall be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) “Historical Fair Market Value” means the volume
weighted average price of the Ordinary Shares during the ten (10) trading day period ending on the trading day prior to the first date on which the Ordinary Shares trade on the applicable exchange or in the applicable market, regular way,
without the right to receive such rights. No Ordinary Shares shall be issued at less than their par value. 
 4.1.2. Extraordinary
Dividends. If the Company, at any time while the Warrants are outstanding and unexpired, pays to all or substantially all of the holders of the Ordinary Shares a dividend or makes a distribution in cash, securities or other assets on account of
such Ordinary Shares (or other shares into which the Warrants are convertible), other than (a) as described in subsection 4.1.1 above, (b) Ordinary Cash Dividends (as defined below), (c) to satisfy the redemption
rights of the holders of the Ordinary Shares in connection with a proposed initial Business Combination, (d) to satisfy the redemption rights of the holders of the Ordinary Shares in connection with a shareholder vote to amend the
Company’s amended and restated memorandum and articles of association (i) to modify the substance or timing of the Company’s obligation to provide holders of Ordinary Shares the right to have their shares redeemed in connection with
the Company’s initial Business Combination or to redeem 100% of the Company’s public shares if it does not complete its initial Business Combination within the time period required by the Company’s Amended and Restated Memorandum and
Articles of Association, as amended from time to time, or (ii) with respect to any other provision relating to the rights of holders of Ordinary Shares, (e) as a result of the repurchase of Ordinary Shares by the Company if a proposed
initial Business Combination is presented to the shareholders of the Company for approval or (f) in connection with the redemption of public shares upon the failure of the Company to complete its initial Business Combination and any subsequent
distribution of its assets upon its liquidation (any such non-excluded event being referred to herein as an “Extraordinary Dividend”), then the Warrant Price shall be decreased,
effective immediately after the effective date of such Extraordinary Dividend, by the amount of cash and/or the fair market value (as determined by the Company’s board of directors (the “Board”), in good faith) of any
securities or other assets paid on each Ordinary Share in respect of such Extraordinary Dividend. For purposes of this subsection 4.1.2, “Ordinary Cash Dividends” means any cash dividend or cash
distribution which, when combined on a per share basis, with the per share amounts of all other cash dividends and cash distributions paid on the Ordinary Shares during the 365-day period ending on the date of
declaration of such dividend or distribution to the extent it does not exceed $0.50 (which amount shall be adjusted to appropriately reflect any of the events referred to in other subsections of this Section 4 and excluding
cash dividends or cash distributions that resulted in an adjustment to the Warrant Price or to the number of Ordinary Shares issuable on exercise of each Warrant). 

4.2. Aggregation of Shares. If after the date hereof, and subject to the provisions of Section 4.6 hereof,
the number of issued and outstanding Ordinary Shares is decreased by a consolidation, combination, reverse share sub-division or reclassification of Ordinary Shares or other similar event, then, on the
effective date of such consolidation, combination, reverse share sub-division, reclassification or similar event, the number of Ordinary Shares issuable on exercise of each Warrant shall be decreased in
proportion to such decrease in issued and outstanding Ordinary Shares. 

 4.3. Adjustments in Exercise Price. Whenever the number of Ordinary Shares
purchasable upon the exercise of the Warrants is adjusted, as provided in subsection 4.1.1 or Section 4.2 above, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such
Warrant Price immediately prior to such adjustment by a fraction (x) the numerator of which shall be the number of Ordinary Shares purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (y) the denominator
of which shall be the number of Ordinary Shares so purchasable immediately thereafter. 
 4.4. Replacement of Securities upon
Reorganization, etc. In case of any reclassification or reorganization of the issued and outstanding Ordinary Shares (other than a change covered by Section 4.1 or
Section 4.2 hereof or that solely affects the par value of such Ordinary Shares), or in the case of any merger or consolidation of the Company with or into another corporation (other than a consolidation or merger in which
the Company is the continuing corporation and that does not result in any reclassification or reorganization of the issued and outstanding Ordinary Shares), or in the case of any sale or conveyance to another corporation or entity of the assets or
other property of the Company as an entirety or substantially as an entirety, the holders of the Warrants shall thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu
of the Ordinary Shares of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares or stock or other securities or property (including cash) receivable upon
such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the Warrants would have received if such holder had exercised his, her or its Warrant(s) immediately prior
to such event (the “Alternative Issuance”); provided, however, that if the holders of the Ordinary Shares were entitled to exercise a right of election as to the kind or amount of securities, cash or other assets receivable
upon such consolidation or merger, then the kind and amount of securities, cash or other assets constituting the Alternative Issuance for which each Warrant shall become exercisable shall be deemed to be the weighted average of the kind and amount
received per share by the holders of the Ordinary Shares in such consolidation or merger that affirmatively make such election; provided further that if less than 70% of the consideration receivable by the holders of the Ordinary
Shares in the applicable event is payable in the form of shares in the successor entity that is listed for trading on a national securities exchange or is quoted in an established
over-the-counter market, or is to be so listed for trading or quoted immediately following such event, and if the Registered Holder properly exercises the Warrant within
thirty (30) days following the public disclosure of the consummation of such applicable event by the Company pursuant to a Current Report on Form 8-K filed with the Commission, the Warrant Price shall be
reduced by an amount (in dollars) equal to the difference of (i) the Warrant Price in effect prior to such reduction minus (ii) (A) the Per Share Consideration (as defined below) (but in no event less than zero) minus (B) the
Black-Scholes Warrant Value (as defined below). The “Black-Scholes Warrant Value” means the value of a Warrant immediately prior to the consummation of the applicable event based on the Black-Scholes Warrant Model for an
Uncapped American Call on Bloomberg Financial Markets (assuming zero dividends) (“Bloomberg”). For purposes of calculating such amount, (i) the price of each Ordinary Share shall be the volume weighted average
price of the Ordinary Shares during the ten (10) trading day period ending on the trading day prior to the effective date of the applicable event, (ii) the assumed volatility shall be the 90 day volatility obtained from the HVT function on
Bloomberg determined as of the trading day immediately prior to the day of the announcement of the applicable event and (iii) the assumed risk-free interest rate shall correspond to the U.S. Treasury rate for a period equal to the remaining
term of the Warrant. “Per Share Consideration” means (i) if the consideration paid to holders of the Ordinary Shares consists exclusively of cash, the amount of such cash per Ordinary Share, and (ii) in all other
cases, the volume weighted average price of the Ordinary Shares during the ten (10) trading day period ending on the trading day prior to the effective date of the applicable event. If any reclassification or reorganization also results in a
change in Ordinary Shares covered by subsection 4.1.1, then such adjustment shall be made pursuant to subsection 4.1.1 or Sections 4.2, 4.3 and this
Section 4.4. The provisions of this Section 4.4 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers. In no event shall the
Warrant Price be reduced to less than the par value per share issuable upon exercise of such Warrant. 

 4.5. Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the
number of shares issuable upon exercise of a Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from such adjustment and the increase or decrease, if any, in the number
of shares purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon the occurrence of any event specified in
Sections 4.1, 4.2, 4.3, or 4.4, the Company shall give written notice of the occurrence of such event to each holder of a Warrant, at the last address set forth for such holder in the Warrant Register,
of the record date or the effective date of the event. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such event. 

4.6. No Fractional Shares. Notwithstanding any provision contained in this Agreement to the contrary, the Company shall not issue
fractional shares upon the exercise of Warrants. If, by reason of any adjustment made pursuant to this Section 4, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional
interest in a share, the Company shall, upon such exercise, round down to the nearest whole number the number of Ordinary Shares to be issued to such holder. 

4.7. Form of Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this
Section 4, and Warrants issued after such adjustment may state the same Warrant Price and the same number of shares as is stated in the Warrants initially issued pursuant to this Agreement; provided, however,
that the Company may at any time in its sole discretion make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned, whether in
exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed. 
 5. Transfer and Exchange of
Warrants. 
 5.1. Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding
Warrant upon the Warrant Register, upon surrender of such Warrant for transfer, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new Warrant representing an
equal aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. In the case of certificated Warrants, the Warrants so cancelled shall be delivered by the Warrant Agent to the Company from time to time
upon request. 
 5.2. Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written
request for exchange or transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants;
provided further, however that in the event that a Warrant surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange thereof until the Warrant Agent
has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants must also bear a restrictive legend. 

5.3. Fractional Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which shall result
in the issuance of a warrant certificate or book-entry position for a fraction of a Warrant. 
 5.4. Service Charges. No service
charge shall be made for any exchange or registration of transfer of Warrants. 
 5.5. Warrant Execution and Countersignature. The
Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the terms of this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever
required by the Warrant Agent, shall supply the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose. 
 6.
Other Provisions Relating to Rights of Holders of Warrants. 
 6.1. No Rights as Shareholder. A Warrant does not entitle the
Registered Holder thereof to any of the rights of a shareholder of the Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights to vote or to consent or to receive notice as
shareholders in respect of the meetings of shareholders or the election of directors of the Company or any other matter. 

 6.2. Lost, Stolen, Mutilated, or Destroyed Warrants . If any Warrant is lost, stolen,
mutilated, or destroyed, the Company and the Warrant Agent may on such terms as to indemnity or otherwise as they may in their discretion impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of
like denomination, tenor, and date as the Warrant so lost, stolen, mutilated, or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated, or destroyed
Warrant shall be at any time enforceable by anyone. 
 6.3. Reservation of Ordinary Shares. The Company shall at all times reserve
and keep available a number of its authorized but unissued Ordinary Shares that shall be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement. 

6.4. Registration of Ordinary Shares. The Company agrees that as soon as practicable, but in no event later than fifteen
(15) Business Days after the closing of its initial Business Combination, it shall use its commercially reasonable efforts to file with the Commission a registration statement for the registration, under the Securities Act, of the Ordinary
Shares issuable upon exercise of the Warrants. The Company shall use its commercially reasonable efforts to cause the same to become effective within sixty (60) Business Days following the closing of its initial Business Combination and to
maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the Warrants in accordance with the provisions of this Agreement. If any such registration statement has not been declared
effective by the sixtieth (60th) Business Day following the closing of the Business Combination, holders of the Warrants shall have the right, during the period beginning on the sixty-first (61st) Business Day after the closing of the Business Combination and ending upon such registration statement being declared effective by the Commission, and during any other period when the Company shall
fail to have maintained an effective registration statement covering the issuance of the Ordinary Shares issuable upon exercise of the Warrants, to exercise such Warrants on a “cashless basis,” by exchanging the Warrants (in accordance
with Section 3(a)(9) of the Securities Act or another exemption) for that number of Ordinary Shares equal to the quotient obtained by dividing (x) the product of the number of Ordinary Shares underlying the Warrants, multiplied by the
excess of the Last Reported Sale Price less the Warrant Price by (y) the Last Reported Sale Price. The date that notice of “cashless exercise” is received by the Warrant Agent shall be conclusively determined by the Warrant
Agent. 
 7. Concerning the Warrant Agent and Other Matters. 

7.1. Payment of Taxes. The Company shall from time to time promptly pay all taxes and charges that may be imposed upon the Company or
the Warrant Agent in respect of the issuance or delivery of Ordinary Shares upon the exercise of the Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares. 

7.2. Resignation, Consolidation, or Merger of Warrant Agent. 

7.2.1. Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties
and be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the
Company shall appoint in writing a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of thirty (30) days after it has been notified in writing of such resignation or
incapacity by the Warrant Agent or by the holder of a Warrant (who shall, with such notice, submit his, her or its Warrant for inspection by the Company), then the holder of any Warrant may apply to the Supreme Court of the State of New York for the
County of New York for the appointment of a successor Warrant Agent at the Company’s cost. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation or other entity organized and existing under the
laws of the State of New York, in good standing and having its principal office in the United States of America, and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state
authority. After appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties, and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent
hereunder, without any further act or deed; but if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring

 
to such successor Warrant Agent all the authority, powers, and rights of such predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent the Company shall make, execute,
acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting in and confirming to such successor Warrant Agent all such authority, powers, rights, immunities, duties, and obligations. 

7.2.2. Notice of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice
thereof to the predecessor Warrant Agent and the Transfer Agent for the Ordinary Shares not later than the effective date of any such appointment. 

7.2.3. Merger or Consolidation of Warrant Agent. Any entity into which the Warrant Agent may be merged or with which it may be
consolidated or any entity resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor Warrant Agent under this Agreement without any further act. 

7.3. Fees and Expenses of Warrant Agent. 

7.3.1. Remuneration. The Company agrees to pay the Warrant Agent reasonable remuneration for its services as such Warrant Agent
hereunder and shall, pursuant to its obligations under this Agreement, reimburse the Warrant Agent upon demand for all expenditures that the Warrant Agent may reasonably incur in the execution of its duties hereunder. 

7.3.2. Further Assurances. The Company agrees to perform, execute, acknowledge, and deliver or cause to be performed, executed,
acknowledged, and delivered all such further and other acts, instruments, and assurances as may reasonably be required by the Warrant Agent for the carrying out or performing of the provisions of this Agreement. 

7.4. Liability of Warrant Agent. 

7.4.1. Reliance on Company Statement. Whenever in the performance of its duties under this Agreement, the Warrant Agent shall deem it
necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed
to be conclusively proved and established by a statement signed by the Chief Executive Officer, the President, the Chief Financial Officer, Chief Operating Officer, the General Counsel, the Secretary or the Chairman of the Board of the Company and
delivered to the Warrant Agent. The Warrant Agent may rely upon such statement for any action taken or suffered in good faith by it pursuant to the provisions of this Agreement. 

7.4.2. Indemnity. The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct, fraud or bad
faith. The Company agrees to indemnify the Warrant Agent and save it harmless against any and all liabilities, including judgments, out-of-pocket costs and reasonable
outside counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement, except as a result of the Warrant Agent’s gross negligence, willful misconduct, fraud or bad faith. 

7.4.3. Exclusions. The Warrant Agent shall have no responsibility with respect to the validity of this Agreement or with respect to
the validity or execution of any Warrant (except its countersignature thereof). The Warrant Agent shall not be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Warrant. The Warrant Agent
shall not be responsible to make any adjustments required under the provisions of Section 4 hereof or responsible for the manner, method, or amount of any such adjustment or the ascertaining of the existence of facts that
would require any such adjustment; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any Ordinary Shares to be issued pursuant to this Agreement or any Warrant or as to
whether any Ordinary Shares shall, when issued, be valid and fully paid and nonassessable. 
 7.5. Acceptance of Agency. The Warrant
Agent hereby accepts the agency established by this Agreement and agrees to perform the same upon the terms and conditions herein set forth and among other things, shall account promptly to the Company with respect to Warrants exercised and
concurrently account for, and pay to the Company, all monies received by the Warrant Agent for the purchase of Ordinary Shares through the exercise of the Warrants. 

 7.6. Waiver. The Warrant Agent has no right of
set-off or any other right, title, interest or claim of any kind (“Claim”) in, or to any distribution of, the Trust Account (as defined in that certain Investment Management Trust
Agreement, dated as of the date hereof, by and between the Company and Continental Stock Transfer & Trust Company as trustee thereunder) and hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against
the Trust Account for any reason whatsoever. The Warrant Agent hereby waives any and all Claims against the Trust Account and any and all rights to seek access to the Trust Account. 

8. Miscellaneous Provisions.

bind and inure to the benefit of their respective successors and assigns.

of the Warrants shall be governed in all respects by the laws of the State of New York. Subject to applicable law, the Company hereby agrees that any action, proceeding or claim against it arising out of or relating in any way to this Agreement
shall be brought and enforced in the courts of the State of New York or the United States District Court for the Southern District of New York, and irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive forum for any such

 Any person or entity purchasing or otherwise acquiring any interest in the Warrants shall be
deemed to have notice of and to have consented to the forum provisions in this Section 8.3. If any action, the subject matter of which is within the scope the forum provisions above, is filed in a court other than a court
located within the State of New York or the United States District Court for the Southern District of New York (a “foreign action”) in the name of any warrant holder, such warrant holder shall be deemed to have consented to: (x) the
personal jurisdiction of the state and federal courts located within the State of New York or the United States District Court for the Southern District of New York in connection with any action brought in any such court to enforce the forum
provisions (an “enforcement action”), and (y) having service of process made upon such warrant holder in any such enforcement action by service upon such warrant holder’s counsel in the foreign action as agent for such warrant
holder. 
 8.4. Persons Having Rights under this Agreement. Nothing in this Agreement shall be construed to confer upon, or give to,
any person, corporation or other entity other than the parties hereto and the Registered Holders of the Warrants any right, remedy, or claim under or by reason of this Agreement or of any covenant, condition, stipulation, promise, or agreement
hereof. All covenants, conditions, stipulations, promises, and agreements contained in this Agreement shall be for the sole and exclusive benefit of the parties hereto and their successors and assigns and of the Registered Holders of the Warrants.

 8.5. Examination of the Warrant Agreement. A copy of this Agreement shall be available at all reasonable times at the office of
the Warrant Agent in the United States of America, for inspection by the Registered Holder of any Warrant. The Warrant Agent may require any such holder to submit such holder’s Warrant for inspection by the Warrant Agent. 

8.6. Counterparts. This Agreement may be executed in any number of original or facsimile counterparts and each of such counterparts
shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument. 

8.7. Effect of Headings. The section headings herein are for convenience only and are not part of this Agreement and shall not affect
the interpretation thereof. 
 8.8. Amendments. This Agreement may be amended by the parties hereto without the consent of any
Registered Holder for the purpose of (i) curing any ambiguity or to correct any mistake, including to conform the provisions hereof to the description of the terms of the Warrants and this Agreement set forth in the Prospectus, or defective
provision contained herein, (ii) amending the definition of “Ordinary Cash Dividend” as contemplated by and in accordance with the second sentence of subsection 4.1.2 or (iii) adding or changing any
provisions with respect to matters or questions arising under this Agreement as the parties may deem necessary or desirable and that the parties deem shall not adversely affect the rights of the Registered Holders under this Agreement. All other
modifications or amendments, including any modification or amendment to increase the Warrant Price or shorten the Exercise Period, shall require the vote or written consent of the Registered Holders of 65% of the then-outstanding Warrants.
Notwithstanding the foregoing, the Company may lower the Warrant Price or extend the duration of the Exercise Period pursuant to Sections 3.1 and 3.2, respectively, without the consent of the Registered Holders. 

8.9. Severability. This Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision hereof
shall not affect the validity or enforceability of this Agreement or of any other term or provision hereof. Furthermore, in lieu of any such invalid or unenforceable term or provision, the parties hereto intend that there shall be added as a part of
this Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible and be valid and enforceable.

Certificate 
 This Warrant Certificate certifies that
[                ], or registered assigns, is the registered holder of [                ]
warrant(s) (the “Warrants” and each, a “Warrant”) to purchase Class A ordinary shares, $0.0001 par value (“Ordinary Shares”), of Horizon Acquisition Corporation, a
Cayman Islands exempted company (the “Company”). Each Warrant entitles the holder, upon exercise during the period set forth in the Warrant Agreement referred to below, to receive from the Company that number of fully paid
and nonassessable Ordinary Shares as set forth below, at the exercise price (the “Exercise Price”) as determined pursuant to the Warrant Agreement, payable in lawful money (or through “cashless

the conditions set forth herein and in the Warrant Agreement. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement. 

Each whole Warrant is initially exercisable for one fully paid and non-assessable Ordinary Share.
Fractional shares shall not be issued upon exercise of any Warrant. The number of Ordinary Shares issuable upon exercise of the Warrants is subject to adjustment upon the occurrence of certain events as set forth in the Warrant Agreement. 

The initial Exercise Price per one Ordinary Share for any Warrant is equal to $15.00 per share. The Exercise Price is subject to adjustment
upon the occurrence of certain events as set forth in the Warrant Agreement. 
 Subject to the conditions set forth in the Warrant
Agreement, the Warrants may be exercised only during the Exercise Period and to the extent not exercised by the end of such Exercise Period, such Warrants shall become void. The Warrants are not subject to redemption by the Company. 

Reference is hereby made to the further provisions of this Warrant Certificate set forth on the reverse hereof and such further provisions
shall for all purposes have the same effect as though fully set forth at this place.

 [Form of Warrant Certificate] 

[Reverse] 
 The Warrants
evidenced by this Warrant Certificate are part of a duly authorized issue of Warrants entitling the holder on exercise to receive [                ] Ordinary Shares and
are issued or to be issued pursuant to a Warrant Agreement dated as of October 15, 2021 (the “Warrant Agreement”), duly executed and delivered by the Company to Continental Stock Transfer & Trust Company, a New
York limited purpose company, as warrant agent (the “Warrant Agent”), which Warrant Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby referred to for a description of the
rights, limitation of rights, obligations, duties and immunities thereunder of the Warrant Agent, the Company and the holders (the words “holders” or “holder” meaning the Registered Holders or
Registered Holder, respectively) of the Warrants. A copy of the Warrant Agreement may be obtained by the holder hereof upon written request to the Company. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings
given to them in the Warrant Agreement. 
 Warrants may be exercised at any time during the Exercise Period set forth in the Warrant
Agreement. The holder of Warrants evidenced by this Warrant Certificate may exercise them by surrendering this Warrant Certificate, with the form of Election to Purchase set forth hereon properly completed and executed, together with payment of the
Exercise Price as specified in the Warrant Agreement (or through “cashless exercise” as provided for in the Warrant Agreement) at the principal corporate trust office of the Warrant Agent. In the event that upon any exercise of
Warrants evidenced hereby the number of Warrants exercised shall be less than the total number of Warrants evidenced hereby, there shall be issued to the holder hereof or his, her or its assignee, a new Warrant Certificate evidencing the number of
Warrants not exercised. 
 Notwithstanding anything else in this Warrant Certificate or the Warrant Agreement, no Warrant may be exercised
unless at the time of exercise (i) a registration statement covering the issuance of the Ordinary Shares to be issued upon exercise is effective under the Securities Act and (ii) a prospectus thereunder relating to the Ordinary Shares is
current, except through “cashless exercise” as provided for in the Warrant Agreement. 
 The Warrant Agreement provides
that upon the occurrence of certain events the number of Ordinary Shares issuable upon exercise of the Warrants set forth on the face hereof may, subject to certain conditions, be adjusted. If, upon exercise of a Warrant, the holder thereof would be
entitled to receive a fractional interest in an Ordinary Share, the Company shall, upon exercise, round down to the nearest whole number of Ordinary Shares to be issued to the holder of the Warrant. 

Warrant Certificates, when surrendered at the principal corporate trust office of the Warrant Agent by the Registered Holder thereof in person
or by legal representative or attorney duly authorized in writing, may be exchanged, in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service charge, for another Warrant Certificate or
Warrant Certificates of like tenor evidencing in the aggregate a like number of Warrants. 
 Upon due presentation for registration of
transfer of this Warrant Certificate at the office of the Warrant Agent a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange
for this Warrant Certificate, subject to the limitations provided in the Warrant Agreement, without charge except for any tax or other governmental charge imposed in connection therewith. 

The Company and the Warrant Agent may deem and treat the Registered Holder(s) hereof as the absolute owner(s) of this Warrant
Certificate (notwithstanding any notation of ownership or other writing hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the holder(s) hereof, and for all other purposes, and neither the Company nor the
Warrant Agent shall be affected by any notice to the contrary. Neither the Warrants nor this Warrant Certificate entitles any holder hereof to any rights of a shareholder of the Company. 

 Election to Purchase 

(To Be Executed Upon Exercise of Warrant) 

The undersigned hereby irrevocably elects to exercise the right, represented by this Warrant Certificate, to receive
[                ] Ordinary Shares and herewith tenders payment for such Ordinary Shares to the order of Horizon Acquisition Corporation (the
“Company”) in the amount of $[                ] in accordance with the terms hereof. The undersigned requests that a certificate for such
Ordinary Shares be registered in the name of [                ], whose address is
[                ] and that such Ordinary Shares be delivered to [                ] whose
address is [                ]. If said [                ] number of Ordinary Shares is
less than all of the Ordinary Shares purchasable hereunder, the undersigned requests that a new Warrant Certificate representing the remaining balance of such Ordinary Shares be registered in the name of
[                ], whose address is [                ] and that such Warrant Certificate
be delivered to [                ], whose address is [                ]. 

In the event that the Warrant is a Private Placement Warrant that is to be exercised on a “cashless” basis pursuant to
subsection 3.3.1(b) of the Warrant Agreement, the number of Ordinary Shares that this Warrant is exercisable for shall be determined in accordance with subsection 3.3.1(b) of the Warrant
Agreement. 
 In the event that the Warrant is to be exercised on a “cashless” basis pursuant to
Section 6.4 of the Warrant Agreement, the number of Ordinary Shares that this Warrant is exercisable for shall be determined in accordance with Section 6.4 of the Warrant Agreement. 

In the event that the Warrant may be exercised, to the extent allowed by the Warrant Agreement, through cashless exercise (i) the number
of Ordinary Shares that this Warrant is exercisable for would be determined in accordance with the relevant section of the Warrant Agreement which allows for such cashless exercise and (ii) the holder hereof shall complete the following: The
undersigned hereby irrevocably elects to exercise the right, represented by this Warrant Certificate, through the cashless exercise provisions of the Warrant Agreement, to receive Ordinary Shares. If said number of shares is less than all of the
Ordinary Shares purchasable hereunder (after giving effect to the cashless exercise), the undersigned requests that a new Warrant Certificate representing the remaining balance of such Ordinary Shares be registered in the name of
[                ], whose address is [                ] and that such Warrant Certificate
be delivered to [                ], whose address is [                ].

Execution Version 
 PRIVATE
WARRANT AGREEMENT 
 Dated October 18, 2021 

THIS WARRANT AGREEMENT (this “Agreement”), dated October 18, 2021, is by and between Hoya Intermediate, LLC, a
Delaware limited liability company (the “Company”), Hoya Topco, LLC, a Delaware limited liability company (“Hoya Topco”) and any transferees of Hoya Topco permitted pursuant to this Agreement who
execute valid joinders hereto (Hoya Topco and such permitted transferees, the “Warrantholders”). 
 WHEREAS,
pursuant to that certain Transaction Agreement, dated as of April 21, 2021 (as amended, restated, supplemented or otherwise modified from time to time, the “Transaction Agreement”) by and among the Company, Horizon
Sponsor, LLC, a Delaware limited liability company (“Sponsor”), Hoya Topco, Horizon Acquisition Corporation, a Cayman Islands exempted company, and Vivid Seats, Inc., a Delaware corporation (“VS PubCo”
and collectively with Hoya Topco and the Company, the “VS Entities”), among other things, the VS Entities agreed to consummate a Pre-Closing Restructuring (as defined in
the Transaction Agreement); 
 WHEREAS, pursuant to the Pre-Closing Restructuring, the Company
agreed to grant Hoya Topco warrants to purchase 3,000,000 common units of the Company (“Intermediate Common Units”) at an exercise price of $10.00 per unit (the “Warrants”); 

WHEREAS, the Company desires to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and exercised,
and the respective rights, limitation of rights, and immunities of the Company and the Warrantholders; and 
 WHEREAS, all acts and things
have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company (if a physical certificate is issued), as provided herein, the valid, binding and legal obligations of the Company, and to authorize the
execution and delivery of this Agreement. 
 NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto
agree as follows: 
  

	1.	 Warrants. 

1.1. Form of Warrant. Each Warrant shall initially be issued in registered form only. 

1.2. Effect of Countersignature. If a physical certificate is issued, unless and until countersigned by the Company pursuant to this
Agreement, a certificated Warrant shall be invalid and of no effect and may not be exercised by the holder thereof. 
 1.3. Registration. 

1.3.1. Warrant Register. The Company shall maintain books (the “Warrant Register”), for the registration of
original issuance and the registration of transfer of the Warrants. Upon the initial issuance of the Warrants in book-entry form, the Company shall issue and register the Warrants in the names of the respective holders thereof in the denominations
issued to such holders. 
 If requested, the registered holder of a Warrant shall be issued a definitive certificate in physical form
evidencing such Warrants (“Definitive Warrant Certificates”) which shall be in the form annexed hereto as Exhibit A. Each Warrant shall bear the legend set forth in
Exhibit B. 
 Physical certificates, if issued, shall be signed by, or bear the facsimile signature of, the
Chairman of the Board, Chief Executive Officer, President, Chief Financial Officer, Chief Operating Officer, General Counsel, Secretary or other principal officer of the Company. In the event the person whose facsimile signature has been placed upon
any Warrant shall have ceased to serve in the capacity in which such person signed the Warrant before such Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance. 

 1.3.2. Registered Holder. Prior to due presentment for registration of transfer of
any Warrant, the Company may deem and treat the person in whose name such Warrant is registered in the Warrant Register (the “Registered Holder”) as the absolute owner of such Warrant and of each Warrant represented thereby,
for the purpose of any exercise thereof, and for all other purposes, and the Company shall not be affected by any notice to the contrary. 

1.4. Fractional Warrants. The Company shall not issue fractional Warrants. 

 

	2.	 Terms and Exercise of Warrants. 

2.1. Warrant Price. Each whole Warrant shall entitle the Registered Holder thereof, subject to the provisions of such Warrant and of
this Agreement, to purchase from the Company the number of Intermediate Common Units stated therein, at the price of $10.00 per unit, subject to the adjustments provided in Section 3 hereof and in the last sentence of this
Section 2.1. The term “Warrant Price” as used in this Agreement shall mean the price per unit (including in cash or by payment of Warrants pursuant to a “cashless exercise,” to the extent
permitted hereunder) described in the prior sentence at which Intermediate Common Units may be purchased at the time a Warrant is exercised. The Company in its sole discretion may lower the Warrant Price at any time prior to the Expiration Date (as
defined below) for a period of not less than fifteen Business Days (unless otherwise required by the Commission, any national securities exchange on which the Warrants are listed or applicable law); provided that the Company shall provide at least
five days’ prior written notice of such reduction to Registered Holders of the Warrants; and provided further, that any such reduction shall be identical among all of the Warrants. The term “Business Day” means a day,
other than a Saturday, Sunday or federal holiday on which banks in New York City are generally open for normal business. 
 2.2. Duration
of Warrants. A Warrant may be exercised only during the period (the “Exercise Period”) (A) commencing on the date that is thirty (30) days after the date hereof and (B) terminating at 5:00 p.m., New York
City time on the date that is ten (10) years after the date hereof (the “Expiration Date”); provided, however, that the exercise of any Warrant shall be subject to the satisfaction of any applicable
conditions, as set forth in subsection 2.3.2 below, with respect to an effective registration statement or a valid exemption therefrom being available; provided, further, that any Warrant may be classified by
the Company upon the issuance of such Warrant, with the consent of the Warrantholder, as an “Option Contingent Warrant” (it being understood that the Warrants granted to Hoya Topco on the date hereof shall consist of Option Contingent
Warrants to purchase 1,000,000 Intermediate Common Units and other Warrants to purchase 2,000,000 Intermediate Common Units), and any such Option Contingent Warrant shall be exercisable only to the extent, and following, the forfeiture or
cancellation of an equivalent number of options to purchase shares of Class A common stock of VS PubCo (“PubCo Common Stock”) which options are issued pursuant to the 2021 Vivid Seats Equity Incentive Plan within thirty
(30) days of the date hereof with an exercise price equal to the Warrant Price (or, if the fair market value of such shares of PubCo Common Stock is greater than the Warrant Price at the time of issuance, the fair market value of a share of
PubCo Common Stock) (such options, the “Matching PubCo Options”). For the avoidance of doubt, upon the forfeiture or cancellation of any Matching PubCo Option, an equivalent number of Option Contingent Warrants shall become
exercisable pursuant to the terms hereof applicable to Warrants. Each Warrant not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease at 5:00
p.m. New York City time on the Expiration Date. The Company in its sole discretion may extend the duration of the Warrants by delaying the Expiration Date; provided that the Company shall provide at least twenty (20) days prior
written notice of any such extension to Registered Holders of the Warrants and, provided further that any such extension shall be identical in duration among all the Warrants. 

2.3. Exercise of Warrants. 

2.3.1. Payment. Subject to the provisions of the Warrant and this Agreement, a Warrant may be exercised by the Registered Holder
thereof by delivering to the Company (i) the Definitive Warrant Certificate evidencing the Warrants to be exercised, (ii) an election to purchase (“Election to Purchase”) any Intermediate Common Units pursuant to
the exercise of a Warrant, properly completed and executed by the Registered Holder on 

  
 2 

 
the reverse of the Definitive Warrant Certificate, and (iii) the payment in full of the Warrant Price for each Intermediate Common Unit as to which the Warrant is exercised and any and all
applicable taxes due in connection with the exercise of the Warrant, the exchange of the Warrant for the Intermediate Common Units and the issuance of such Intermediate Common Units, as follows: 

(a) in lawful money of the United States, in good certified check or good bank draft payable to the order of the Company; or 

(b) with respect to any Warrant, by surrendering the Warrants for that number of Intermediate Common Units equal to the quotient obtained by
dividing (x) the product of the number of Intermediate Common Units underlying the Warrants, multiplied by the excess of the “Last Reported Sale Price” (as defined in this subsection 2.3.1(b))
less the Warrant Price by (y) the Last Reported Sale Price. The “Last Reported Sale Price” shall mean the last reported sale price of the Intermediate Common Units on the date prior to the date on which notice of
exercise of the Warrant is sent to the Company. 
 2.3.2. Issuance of Intermediate Common Units on Exercise. As soon as practicable
after the exercise of any Warrant and the clearance of the funds in payment of the Warrant Price (if payment is pursuant to subsection 2.3.1(a)), the Company shall issue to the Registered Holder of such Warrant a book-entry
position or certificate, as applicable, for the number of Intermediate Common Units to which he, she or it is entitled, registered in such name or names as may be directed by him, her or it on the register of members of the Company, and if such
Warrant shall not have been exercised in full, a new book-entry position or countersigned Warrant, as applicable, for the number of units as to which such Warrant shall not have been exercised. Notwithstanding the foregoing, the Company shall not be
obligated to deliver any Intermediate Common Units pursuant to the exercise of a Warrant and shall have no obligation to settle such Warrant exercise unless (i) a registration statement under the Securities Act of 1933, as amended (the
“Securities Act”), with respect to the Intermediate Common Units underlying the Warrants is then effective and a prospectus relating thereto is current or (ii) a valid exemption from registration is available. No Warrant
shall be exercisable and the Company shall not be obligated to issue Intermediate Common Units upon exercise of a Warrant unless the Intermediate Common Units issuable upon such Warrant exercise have been registered, qualified or deemed to be exempt
from registration or qualification under the securities laws of the state of residence of the Registered Holder of the Warrants. Subject to Section 3.6 of this Agreement, a Registered Holder of Warrants may exercise its
Warrants only for a whole number of Intermediate Common Units. If, by reason of any exercise of Warrants on a “cashless basis”, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional
interest in an Intermediate Common Unit, the Company shall round down to the nearest whole number, the number of Intermediate Common Units to be issued to such holder. For the avoidance of doubt, in no event will the Company be required to pay cash
to the holder of any Warrant. 
 2.3.3. Valid Issuance. All Intermediate Common Units issued upon the proper exercise of a Warrant in
conformity with this Agreement shall be validly issued, fully paid and nonassessable. 
 2.3.4. Date of Issuance. Each person in
whose name any book-entry position or certificate, as applicable, for Intermediate Common Units is issued and who is registered in the register of members of the Company shall for all purposes be deemed to have become the holder of record of such
Intermediate Common Units on the date on which the Warrant, or book-entry position representing such Warrant, was surrendered and payment of the Warrant Price was made, irrespective of the date of delivery of such certificate in the case of a
certificated Warrant, except that, if the date of such surrender and payment is a date when the register of members of the Company is closed, such person shall be deemed to have become the holder of such units at the close of business on the next
succeeding date on which the unit transfer books or book-entry system are open. 
  

	3.	 Adjustments. 

3.1. Equity Capitalizations. 

3.1.1. Sub-Divisions. If after the date hereof, and subject to the provisions of
Section 3.6 below, the number of issued and outstanding Intermediate Common Units is increased by a capitalization or unit dividend of Intermediate Common Units, or by a sub-division
of Intermediate Common Units or other similar event, then, on the effective date of such unit capitalization, sub-division or similar event, the number of Intermediate

  
 3 

 
Common Units issuable on exercise of each Warrant shall be increased in proportion to such increase in the issued and outstanding Intermediate Common Units. A rights offering made to all or
substantially all of the holders of Intermediate Common Units entitling holders to purchase Intermediate Common Units at a price less than the “Historical Fair Market Value” (as defined below) shall be deemed a capitalization of a number
of Intermediate Common Units equal to the product of (i) the number of Intermediate Common Units actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or
exercisable for the Intermediate Common Units) multiplied by (ii) one (1) minus the quotient of (x) the price per Intermediate Common Unit paid in such rights offering divided by (y) the Historical Fair Market Value. For purposes
of this subsection 3.1.1, (i) if the rights offering is for securities convertible into or exercisable for Intermediate Common Units, in determining the price payable for Intermediate Common Units, there shall be taken
into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) ”Historical Fair Market Value” means the volume weighted average price of PubCo
Common Stock during the ten (10) trading day period ending on the trading day prior to the first date on which the PubCo Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive such
rights. 
 3.1.2. Extraordinary Dividends. If the Company, at any time while the Warrants are outstanding and unexpired, pays to all
or substantially all of the holders of the Intermediate Common Units a dividend or makes a distribution in cash, securities or other assets on account of such Intermediate Common Units (or other units into which the Warrants are convertible), other
than (a) as described in subsection 3.1.1 above, (b) Ordinary Cash Dividends (as defined below) or (c) as a result of any redemption rights under the Second Amended and Restated Limited Liability Agreement of
the Company, dated as of the date hereof (as amended, modified or restated from time to time, the “Company LLC Agreement”) (any such non-excluded event being referred to herein as an
“Extraordinary Dividend”), then the Warrant Price shall be decreased, effective immediately after the effective date of such Extraordinary Dividend, by the amount of cash and/or the fair market value (as determined by the
Company’s board of managers (the “Board”), in good faith) of any securities or other assets paid on each Intermediate Common Unit in respect of such Extraordinary Dividend. For purposes of this
subsection 3.1.2, “Ordinary Cash Dividends” means any cash dividend or cash distribution which, when combined on a per unit basis, with the per unit amounts of all other cash dividends and cash
distributions paid on the Intermediate Common Units during the 365-day period ending on the date of declaration of such dividend or distribution to the extent it does not exceed $0.50 (which amount shall be
adjusted to appropriately reflect any of the events referred to in other subsections of this Section 3 and excluding cash dividends or cash distributions that resulted in an adjustment to the Warrant Price or to the
number of Intermediate Common Units issuable on exercise of each Warrant). 
 3.2. Aggregation of Units. If after the date hereof,
and subject to the provisions of Section 3.6 hereof, the number of issued and outstanding Intermediate Common Units is decreased by a consolidation, combination, reverse unit
sub-division or reclassification of Intermediate Common Units or other similar event, then, on the effective date of such consolidation, combination, reverse unit
sub-division, reclassification or similar event, the number of Intermediate Common Units issuable on exercise of each Warrant shall be decreased in proportion to such decrease in issued and outstanding
Intermediate Common Units. 
 3.3. Adjustments in Exercise Price. Whenever the number of Intermediate Common Units purchasable upon
the exercise of the Warrants is adjusted, as provided in subsection 3.1.1 or Section 3.2 above, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such Warrant Price
immediately prior to such adjustment by a fraction (x) the numerator of which shall be the number of Intermediate Common Units purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (y) the denominator of
which shall be the number of Intermediate Common Units so purchasable immediately thereafter. 
 3.4. Replacement of Securities upon
Reorganization, etc. In case of any reclassification or reorganization of the issued and outstanding Intermediate Common Units (other than pursuant to a change covered by Section 3.1 or
Section 3.2 hereof or that solely affects the par value of such Intermediate Common Units), or in the case of any merger or consolidation of the Company with or into another entity (other than a consolidation or merger in
which the Company is the continuing entity and that does not result in any reclassification or reorganization of the issued and outstanding Intermediate Common Units), or in the case of any sale or conveyance to another corporation or entity of the
assets or other property of the Company as an entirety or substantially as an 

  
 4 

 
entirety, the holders of the Warrants shall thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu of the
Intermediate Common Units of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of units or stock or other securities or property (including cash) receivable upon
such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the Warrants would have received if such holder had exercised his, her or its Warrant(s) immediately prior
to such event (the “Alternative Issuance”); provided, however, that if the holders of the Intermediate Common Units were entitled (including pursuant to the terms of the Company LLC Agreement) to exercise a right of election
as to the kind or amount of securities, cash or other assets receivable upon such consolidation or merger, then the kind and amount of securities, cash or other assets constituting the Alternative Issuance for which each Warrant shall become
exercisable shall be deemed to be the weighted average of the kind and amount received per unit by the holders of the Intermediate Common Units in such consolidation or merger that affirmatively make such election; provided further
that if less than 70% of the consideration receivable by the holders of the Intermediate Common Units in the applicable event is payable in the form of equity in the successor entity that is listed for trading on a national securities exchange or is
quoted in an established over-the-counter market, or is to be so listed for trading or quoted immediately following such event, and if the Registered Holder properly
exercises the Warrant within thirty (30) days following the public disclosure of the consummation of such applicable event by VS PubCo pursuant to a Current Report on Form 8-K filed with the Commission,
the Warrant Price shall be reduced by an amount (in dollars) equal to the difference of (i) the Warrant Price in effect prior to such reduction minus (ii) (A) the Per Share Consideration (as defined below) (but in no event less than zero)
minus (B) the Black-Scholes Warrant Value (as defined below). The “Black-Scholes Warrant Value” means the value of a Warrant immediately prior to the consummation of the applicable event based on the Black-Scholes
Warrant Model for an Uncapped American Call on Bloomberg Financial Markets (assuming zero dividends) (“Bloomberg”). For purposes of calculating such amount, (i) the price of each Intermediate Common Unit shall be the
volume weighted average price of the PubCo Common Stock during the ten (10) trading day period ending on the trading day prior to the effective date of the applicable event, (ii) the assumed volatility shall be the 90 day volatility
obtained from the HVT function on Bloomberg determined as of the trading day immediately prior to the day of the announcement of the applicable event and (iii) the assumed risk-free interest rate shall correspond to the U.S. Treasury rate for a
period equal to the remaining term of the Warrant. “Per Share Consideration” means (i) if the consideration paid to holders of the Intermediate Common Units consists exclusively of cash, the amount of such cash per
Intermediate Common Unit, and (ii) in all other cases, the volume weighted average price of the PubCo Common Stock during the ten (10) trading day period ending on the trading day prior to the effective date of the applicable event. If any
reclassification or reorganization also results in a change in Intermediate Common Units covered by subsection 3.1.1, then such adjustment shall be made pursuant to subsection 3.1.1 or
Sections 3.2, 3.3 and this Section 3.4. The provisions of this Section 3.4 shall similarly apply to successive reclassifications, reorganizations, mergers or
consolidations, sales or other transfers. In no event shall the Warrant Price be reduced to less than the par value per unit issuable upon exercise of such Warrant. 

3.5. Notices of Changes in Warrant. Upon the occurrence of any event specified in Sections 3.1, 3.2,
3.3, or 3.4, the Company shall give written notice of the occurrence of such event to each holder of a Warrant, at the last address set forth for such holder in the Warrant Register, of the record date or the effective date of the
event. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such event. 
 3.6. No Fractional
Units. Notwithstanding any provision contained in this Agreement to the contrary, the Company shall not issue fractional units upon the exercise of Warrants. If, by reason of any adjustment made pursuant to this
Section 3, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a unit, the Company shall, upon such exercise, round down to the nearest whole number the number
of Intermediate Common Units to be issued to such holder. 
 3.7. Form of Warrant. The form of Warrant need not be
changed because of any adjustment pursuant to this Section 3, and Warrants issued after such adjustment may state the same Warrant Price and the same number of units as is stated in the Warrants initially issued pursuant to
this Agreement; provided, however, that the Company may at any time in its sole discretion make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant
thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed. 

  
 5 

	4.	 Transfer and Exchange of Warrants. 

4.1. Registration of Transfer. The Company shall register the proper transfer pursuant to this Section 4,
from time to time, of any outstanding Warrant upon the Warrant Register, upon surrender of such Warrant for transfer, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such
transfer, a new Warrant representing an equal aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Company. 

4.2. Procedure for Surrender of Warrants. Warrants may be surrendered to the Company, together with a written request for exchange or
transfer, and thereupon the Company shall issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided further,
however that in the event that a Warrant surrendered for transfer bears a restrictive legend, the Company shall not cancel such Warrant and issue new Warrants in exchange thereof until the Company has received an opinion of counsel for the
Company stating that such transfer may be made and indicating whether the new Warrants must also bear a restrictive legend. 
 4.3.
Fractional Warrants. The Company shall not be required to effect any registration of transfer or exchange which shall result in the issuance of a warrant certificate or book-entry position for a fraction of a Warrant. 

4.4. Service Charges. No service charge shall be made for any exchange or registration of transfer of Warrants. 

4.5. Transfer Restrictions. Each Warrant shall be transferrable only (i) to the extent the Intermediate Common Unit underlying
such Warrant would be transferable pursuant to the terms of the Company LLC Agreement, (ii) the transferring Warrantholder and the transferee comply with the applicable requirements of Article VIII of the Company LLC Agreement and
(iii) the transferee executes a valid joinder to this Agreement in a form reasonably acceptable to the Company. 
  

	5.	 Other Provisions Relating to Rights of Holders of Warrants. 

5.1. No Rights as Unitholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a unitholder of the
Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights to vote or to consent or to receive notice as unitholders in respect of the meetings of unitholders or the election of
managers of the Company or any other matter, or any rights under the Company LLC Agreement. 
 5.2. Lost, Stolen, Mutilated, or Destroyed
Warrants. If any Warrant is lost, stolen, mutilated, or destroyed, the Company may on such terms as to indemnity or otherwise as it may in its discretion impose (which shall, in the case of a mutilated Warrant, include the surrender thereof),
issue a new Warrant of like denomination, tenor, and date as the Warrant so lost, stolen, mutilated, or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen,
mutilated, or destroyed Warrant shall be at any time enforceable by anyone. 
 5.3. Reservation of Intermediate Common Units. The
Company shall at all times reserve and keep available a number of its authorized but unissued Intermediate Common Units that shall be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement. 

 

	6.	 Miscellaneous Provisions. 

6.1. Successors. All the covenants and provisions of this Agreement by or for the benefit of the Company or the Warrantholders shall
bind and inure to the benefit of their respective successors and assigns. 
 6.2. Notices. Any notice, statement or demand authorized
by this Agreement to be given or made by the holder of any Warrant to or on the Company shall be sufficiently given when so delivered (i) by electronic mail, (ii) by hand or overnight delivery or (ii) if sent by certified mail or
private courier service within five (5) days after

6.3. Applicable Law and Exclusive Forum. The validity, interpretation, and performance of this Agreement and of the Warrants shall be
governed in all respects by the laws of the State of New York. Subject to applicable law, the Company hereby agrees that any action, proceeding or claim against it arising out of or relating in any way to this Agreement shall be brought and enforced
in the courts of the State of New York or the United States District Court for the Southern District of New York, and irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive forum for any such action, proceeding or claim. The
Company hereby waives any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum. Notwithstanding the foregoing, the provisions of this paragraph will not apply to suits brought to enforce any liability or duty
created by the Exchange Act or any other claim for which the federal district courts of the United States of America are the sole and exclusive forum. 

Any person or entity purchasing or otherwise acquiring any interest in the Warrants shall be deemed to have notice of and to have consented to
the forum provisions in this Section 6.3. If any action, the subject matter of which is within the scope the forum provisions above, is filed in a court other than a court located within the State of New York or the United
States District Court for the Southern District of New York (a “foreign action”) in the name of any warrant holder, such warrant holder shall be deemed to have consented to: (x) the personal jurisdiction of the state and federal
courts located within the State of New York or the United States District Court for the Southern District of New York in connection with any action brought in any such court to enforce the forum provisions (an “enforcement action”), and
(y) having service of process made upon such warrant holder in any such enforcement action by service upon such warrant holder’s counsel in the foreign action as agent for such warrant holder. 

6.4. Persons Having Rights under this Agreement. Nothing in this Agreement shall be construed to confer upon, or give to, any person,
corporation or other entity other than the parties hereto and the Registered Holders of the Warrants any right, remedy, or claim under or by reason of this Agreement or of any covenant, condition, stipulation, promise, or agreement hereof. All
covenants, conditions, stipulations, promises, and agreements contained in this Agreement shall be for the sole and exclusive benefit of the parties hereto and their successors and assigns and of the Registered Holders of the Warrants. 

6.5. Counterparts. This Agreement may be executed in any number of original or facsimile counterparts and each of such counterparts
shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument. 

6.6. Effect of Headings. The section headings herein are for convenience only and are not part of this Agreement and shall not
affect the interpretation thereof. 

  
 7 

 6.7. Amendments. This Agreement may be amended by the Company without the consent of
any Warrantholder for the purpose of (i) curing any ambiguity or to correct any mistake or defective provision contained herein, (ii) amending the definition of “Ordinary Cash Dividend” as contemplated by and in accordance with
the second sentence of subsection 3.1.2 or (iii) adding or changing any provisions with respect to matters or questions arising under this Agreement as the Company may reasonably deem necessary or desirable and that
the Company reasonably deem shall not adversely affect the rights of the Registered Holders under this Agreement. All other modifications or amendments, including any modification or amendment to increase the Warrant Price or shorten the Exercise
Period, shall require the vote or written consent of the Registered Holders of 65% of the then-outstanding Warrants. Notwithstanding the foregoing, the Company may lower the Warrant Price or extend the duration of the Exercise Period pursuant to
Sections 2.1 and 2.2, respectively, without the consent of the Registered Holders. 
 6.8.
Severability. This Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision hereof shall not affect the validity or enforceability of this Agreement or of any other term or provision hereof.
Furthermore, in lieu of any such invalid or unenforceable term or provision, the parties hereto intend that there shall be added as a part of this Agreement a provision as similar in terms to such invalid or unenforceable provision as may be
possible and be valid and enforceable.

CUSIP [ 🌑 ] 

Warrant Certificate 

This Warrant Certificate certifies that
[                ], or registered assigns, is the registered holder of [                ]
warrant(s) (the “Warrants” and each, a “Warrant”) to purchase common units (“Intermediate Common Units”), of Hoya Intermediate, LLC, a Delaware limited liability company
(the “Company”). Each Warrant entitles the holder, upon exercise during the period set forth in the Warrant Agreement referred to below, to receive from the Company that number of fully paid and nonassessable Intermediate
Common Units as set forth below, at the exercise price (the “Exercise Price”) as determined pursuant to the Warrant Agreement, payable in lawful money (or through “cashless exercise” as provided for in
the Warrant Agreement) of the United States of America upon surrender of this Warrant Certificate and payment of the Exercise Price at the corporate office of the Company referred to below, subject to the conditions set forth herein and in the
Warrant Agreement. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement. 

Each whole Warrant is initially exercisable for one fully paid and non-assessable Intermediate Common
Unit. Fractional units shall not be issued upon exercise of any Warrant. The number of Intermediate Common Units issuable upon exercise of the Warrants is subject to adjustment upon the occurrence of certain events as set forth in the Warrant
Agreement. [This Warrant is a “Option Contingent Warrant” and shall be subject to the terms thereof set forth in the Warrant Agreement.] 

The initial Exercise Price per one Intermediate Common Unit for any Warrant is equal to $10.00 per unit. The Exercise Price is subject to
adjustment upon the occurrence of certain events as set forth in the Warrant Agreement. 
 Subject to the conditions set forth in the
Warrant Agreement, the Warrants may be exercised only during the Exercise Period and to the extent not exercised by the end of such Exercise Period, such Warrants shall become void. The Warrants are not subject to redemption by the Company. 

Reference is hereby made to the further provisions of this Warrant Certificate set forth on the reverse hereof and such further provisions
shall for all purposes have the same effect as though fully set forth at this place. 
 This Warrant Certificate shall not be valid unless
signed by the Company. This Warrant Certificate shall be governed by and construed in accordance with the internal laws of the State of New York.

 [Form of Warrant Certificate] 

[Reverse] 
 The Warrants
evidenced by this Warrant Certificate are part of a duly authorized issue of Warrants entitling the holder on exercise to receive [                ] Intermediate Common
Units and are issued or to be issued pursuant to a Warrant Agreement dated as of October 18, 2021 (the “Warrant Agreement”), by and between the Company and the holders of the Warrants, which Warrant Agreement is hereby
incorporated by reference in and made a part of this instrument and is hereby referred to for a description of the rights, limitation of rights, obligations, duties and immunities thereunder of the Company and the holders (the words
“holders” or “holder” meaning the Registered Holders or Registered Holder, respectively) of the Warrants. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings
given to them in the Warrant Agreement. 
 Warrants may be exercised at any time during the Exercise Period set forth in the Warrant
Agreement, subject to the conditions applicable to exercise set forth in the Warrant Agreement. The holder of Warrants evidenced by this Warrant Certificate may exercise them by surrendering this Warrant Certificate, with the form of Election to
Purchase set forth hereon properly completed and executed, together with payment of the Exercise Price as specified in the Warrant Agreement (or through “cashless exercise” as provided for in the Warrant Agreement) at the principal
corporate office of the Company. In the event that upon any exercise of Warrants evidenced hereby the number of Warrants exercised shall be less than the total number of Warrants evidenced hereby, there shall be issued to the holder hereof or his,
her or its assignee, a new Warrant Certificate evidencing the number of Warrants not exercised. 
 Notwithstanding anything else in this
Warrant Certificate or the Warrant Agreement, no Warrant may be exercised unless at the time of exercise (i) a registration statement covering the issuance of the Intermediate Common Units to be issued upon exercise is effective under the
Securities Act and (ii) a prospectus thereunder relating to the Intermediate Common Units is current, except through “cashless exercise” as provided for in the Warrant Agreement. 

The Warrant Agreement provides that upon the occurrence of certain events the number of Intermediate Common Units issuable upon exercise of
the Warrants set forth on the face hereof may, subject to certain conditions, be adjusted. If, upon exercise of a Warrant, the holder thereof would be entitled to receive a fractional interest in an Intermediate Common Unit, the Company shall, upon
exercise, round down to the nearest whole number of Intermediate Common Units to be issued to the holder of the Warrant. 
 Warrant
Certificates, when surrendered at the corporate office of the Company by the Registered Holder thereof in person or by legal representative or attorney duly authorized in writing, may be exchanged, in the manner and subject to the limitations
provided in the Warrant Agreement, but without payment of any service charge, for another Warrant Certificate or Warrant Certificates of like tenor evidencing in the aggregate a like number of Warrants. 

Upon due presentation for registration of transfer of this Warrant Certificate at the corporate office of the Company a new Warrant
Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate, subject to the limitations provided in the Warrant
Agreement, without charge except for any tax or other governmental charge imposed in connection therewith. 
 The Company may deem and treat
the Registered Holder(s) hereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership or other writing hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the
holder(s) hereof, and for all other purposes, and the Company shall not be affected by any notice to the contrary. Neither the Warrants nor this Warrant Certificate entitles any holder hereof to any rights of a unitholder of the Company. 

 Election to Purchase 

(To Be Executed Upon Exercise of Warrant) 

The undersigned hereby irrevocably elects to exercise the right, represented by this Warrant Certificate, to receive
[                ] Intermediate Common Units and herewith tenders payment for such Intermediate Common Units to the order of Hoya Intermediate, LLC (the
“Company”) in the amount of $[                ] in accordance with the terms hereof. The undersigned requests that a certificate for such
Intermediate Common Units be registered in the name of [                ], whose address is
[                ] and that such Intermediate Common Units be delivered to
[                ] whose address is [                ]. If said
[                ] number of Intermediate Common Units is less than all of the Intermediate Common Units purchasable hereunder, the undersigned requests that a new
Warrant Certificate representing the remaining balance of such Intermediate Common Units be registered in the name of [                ], whose address is
[                ] and that such Warrant Certificate be delivered to [                ],
whose address is [                ]. 
 In the event that
the Warrant is a Private Placement Warrant that is to be exercised on a “cashless” basis pursuant to subsection 2.3.1(b) of the Warrant Agreement, the number of Intermediate Common Units that this Warrant is
exercisable for shall be determined in accordance with subsection 2.3.1(b) of the Warrant Agreement. 
 In
the event that the Warrant may be exercised, to the extent allowed by the Warrant Agreement, through cashless exercise (i) the number of Intermediate Common Units that this Warrant is exercisable for would be determined in accordance with the
relevant section of the Warrant Agreement which allows for such cashless exercise and (ii) the holder hereof shall complete the following: The undersigned hereby irrevocably elects to exercise the right, represented by this Warrant
Certificate, through the cashless exercise provisions of the Warrant Agreement, to receive Intermediate Common Units. If said number of units is less than all of the Intermediate Common Units purchasable hereunder (after giving effect to the
cashless exercise), the undersigned requests that a new Warrant Certificate representing the remaining balance of such Intermediate Common Units be registered in the name of
[                ], whose address is [                ] and that such Warrant Certificate
be delivered to [                ], whose address is [                ].
