Ladies
and Gentlemen:


 


This
Subscription Agreement (this “Subscription Agreement”) is being entered
into as of the date set forth on the signature page hereto, by and among Horizon Acquisition Corp., a Cayman Islands exempted
company (“Horizon”), Vivid Seats Inc., a Delaware corporation (“VS
PubCo”), which is a direct wholly owned subsidiary of Hoya Intermediate, LLC, a Delaware limited liability company (“Hoya”),
and the undersigned subscriber (the “Investor”), in connection with
the Transaction Agreement (as amended, modified, supplemented or waived from time to time in accordance with its terms, the “Transaction
Agreement”), dated as of April 21, 2021 by and among Horizon, Horizon Sponsor, LLC, a Delaware limited liability company
(“Sponsor”), Hoya Topco, LLC, a Delaware limited liability company (“Topco”), Hoya, and
VS PubCo pursuant to which, among other things, Horizon will merge with and into VS PubCo (the “Merger”), the
separate corporate existence of Horizon will cease and VS PubCo will be the surviving corporation of the Merger (such merger,
the “Transaction”).


 


In
connection with the Transaction, Horizon and VS PubCo are seeking commitments from interested investors to purchase in connection
with the closing of the Transaction, shares of VS PubCo’s Class A common stock, par value $0.0001 per share (the “Shares”),
in a private placement for a purchase price of $10.00 per share (the “Per Share Purchase
Price”). On or about the date of this Subscription Agreement, Horizon and VS PubCo are entering into subscription
agreements (the “Other Subscription Agreements” and together with
the Subscription Agreement, the “Subscription Agreements”) with certain
other investors (the “Other Investors” and together with the Investor,
the “Investors”), severally and not jointly, pursuant to which the
Investors, severally and not jointly, have agreed to purchase on the closing date of the Transaction, inclusive of the Shares
subscribed for by the Investor, an aggregate amount of up to 22,500,000 Shares, at the Per Share Purchase Price, in which VS PubCo
raises an aggregate of $225,000,000. In addition, on or about the date of this Subscription Agreement, Horizon, Sponsor and Topco
are entering into the Sponsor Support Agreement (the “Sponsor Support Agreement”), pursuant to which Sponsor
agrees to, among other things, (i) vote at any meeting of Horizon’s stockholders, and in any action by written consent of
Horizon’s stockholders, all of its Horizon equity securities in favor of the adoption and approval of the Transaction Agreement
and the transactions contemplated thereby, including the Merger; (ii) be bound by certain other covenants and agreements related
to the Transaction, (iii) be bound by certain transfer restrictions with respect to such securities and (iv) increase the amount
of its subscription of Shares by the amount of any shortfall in available cash held by VS PubCo at the closing of the Transaction
in consideration for a fee, in each case, on the terms and subject to the conditions set forth in the Sponsor Support Agreement.
For the avoidance of doubt, for purposes of this Agreement, the “Other Subscription Agreements” shall not include
the Sponsor Support Agreement. In addition, on or about the date of this Subscription Agreement, Horizon and Sponsor are entering
into the Exchange Agreement (as amended, modified, supplemented or waived from time to time in accordance with its terms, the
 “Exchange Agreement”) pursuant to which, among other things, effective at least one day prior to the Merger,
Sponsor will irrevocably surrender to Horizon 13,599,608 Class B ordinary shares of Horizon, par value $0.0001 per share (the
 “Class B Shares”), in exchange for (a) warrants to purchase 17,000,000 Class A ordinary shares of Horizon,
par value $0.0001 per share (the “Class A Shares”), at an exercise price of $10.00 per share, (b) warrants
to purchase 17,000,000 Class A Shares at an exercise price of $15.00 per share and (c) 50,000 Class A Shares.

of incorporation or bylaws (each as amended as of the Closing Date), by contract or under the General Corporation Law of the State
of Delaware.


 


c.       This
Subscription Agreement has been duly authorized, executed and delivered by each of Horizon and VS PubCo and, assuming that this

against each of Horizon and VS PubCo in accordance with its terms, except as may be limited or otherwise affected by (i) bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium or other laws relating to or affecting the rights of creditors generally,
or (ii) principles of equity, whether considered at law or equity.


 


d.       The
execution and delivery of, and the performance of the transactions contemplated by this Subscription Agreement, including the
issuance and sale of the Shares and the compliance by each of Horizon and VS PubCo with all of the provisions of this Subscription
Agreement and the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation
of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge
or encumbrance upon any of the property or assets of Horizon or VS PubCo, as applicable, pursuant to the terms of (i) any indenture,
mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which Horizon or VS PubCo, as applicable,
is a party or by which Horizon or any of its subsidiaries is bound or to which any of the property or assets of Horizon or VS
PubCo, as applicable, is subject that would reasonably be expected to have a material adverse effect on the business, financial
condition or results of operations of Horizon or VS PubCo, as applicable, taken as a whole (a “Material
Adverse Effect”) or materially affect the validity of the Shares or the legal authority of Horizon or VS PubCo,
as applicable, to comply in all material respects with the terms of this Subscription Agreement; (ii) result in any violation
of the provisions of the organizational documents of Horizon or VS PubCo, as applicable; or (iii) result in any violation of any

over Horizon or VS PubCo, as applicable, or any of their respective properties that would reasonably be expected to have a Material
Adverse Effect or materially affect the validity of the Shares or the legal authority of Horizon or VS PubCo, as applicable, to
comply in all material respects with this Subscription Agreement.


 


e.       As
of their respective dates, all reports (the “SEC Reports”) required
to be filed by Horizon with the U.S. Securities and Exchange Commission (the “SEC”)
complied in all material respects with the applicable requirements of the Securities Act of 1933, as amended, (the “Securities
Act”) and the Securities Exchange Act of 1934, as amended (the “Exchange
Act”) and the rules and regulations of the SEC promulgated thereunder, and none of the SEC Reports, when filed,
contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary
in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The financial
statements of Horizon included in the SEC Reports comply in all material respects with applicable accounting requirements and
the rules and regulations of the SEC with respect thereto as in effect at the time of filing and fairly present in all material
respects the financial position of Horizon as of and for the dates thereof and the results of operations and cash flows for the
periods then ended, subject, in the case of unaudited statements, to normal, year-end audit adjustments. The Investor acknowledges

Special Purpose Acquisition Companies on April 12, 2021 (the “Statement”), (ii) Horizon continues to review
the Statement and its implications, including on the financial statements and other information included in its SEC Reports and
(iii) any restatement, revision or other modification of the SEC Reports in connection with such a review of the Statement or
any subsequent related agreements or other guidance from the Staff of the SEC shall be deemed not material for purposes of this
Agreement, including for purposes of this Section 5(e) and Section 6(f) below. A copy of each SEC Report is available to the Investor
via the SEC’s EDGAR system. There are no outstanding or unresolved comments in comment letters received by Horizon from
the staff of the Division of Corporation Finance of the SEC with respect to any of the SEC Reports.

the accuracy of the Investor’s representations and warranties set forth in Section 6 of this Subscription Agreement, neither
Horizon nor VS PubCo is required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing
or registration with, any court or other federal, state, local or other governmental authority, self-regulatory organization or

a Material Adverse Effect.


 


g.       Except
for such matters as have not had and would not be reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect, there is no (i) action, suit, claim or other proceeding, in each case by or before any governmental authority pending,
or, to the knowledge of Horizon, threatened against Horizon or (ii) judgment, decree, injunction, ruling or order of any governmental

judgment, decree, injunction, ruling or order of any governmental entity or arbitrator outstanding against VS PubCo. Each of Horizon
and VS PubCo is in compliance with all applicable laws, except where such non-compliance would not reasonably be expected to have
a Material Adverse Effect. Horizon has not received any written communication from a governmental authority that alleges that
Horizon is not in compliance with or is in default or violation of any applicable law, except where such non-compliance, default
or violation would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect. VS PubCo has
not received any written communication from a governmental authority that alleges that VS PubCo is not in compliance with or is

k.       VS
PubCo is not, and immediately after receipt of payment for the Shares will not be, an “investment company” within
the meaning of the Investment Company Act of 1940, as amended.


 


l.        Neither
Horizon nor VS PubCo has entered into any agreement or arrangement entitling any agent, broker, investment banker, financial advisor
or other person to any broker’s or finder’s fee or any other commission or similar fee in connection with the transactions

defined below), neither Horizon nor VS PubCo is aware of any person that has been or will be paid (directly or indirectly) remuneration
for solicitation of purchasers in connection with the sale of any Shares.

their respective affiliates is acting as a placement agent in connection with the offer and sale of the Shares to the Investor.


 


a.       Neither
Horizon nor VS PubCo has entered into any side letter or similar agreement with any Other Investor or any other investor in connection
with such Other Investor’s or other investor’s direct or indirect investment in VS PubCo or Horizon other than the
Other Subscription Agreements, the Transaction Agreement and the Sponsor Support Agreement to be entered into substantially concurrently
with the entry into the Transaction Agreement. The Other Subscription Agreements reflect the same Per Share Purchase Price and
other terms and conditions with respect to the purchase of Shares that are no more favorable to such investor thereunder than
the terms of this Subscription Agreement, other than terms particular to the regulatory requirements of such investor or its affiliates
or related funds that are mutual funds or are otherwise subject to regulations related to the timing of funding and the issuance
of the related Shares.


 


6.            Investor
Representations and Warranties. The Investor represents and warrants to Horizon, on behalf of itself and, if applicable,
each account for which it is acquiring the Shares, that:


 


a.       The
Investor (i) is a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) or an institutional
 “accredited investor” (within the meaning of Rule 501(a) under the Securities Act), in each case, satisfying the applicable
requirements set forth on Schedule A, (ii) is acquiring the Shares only for his, her or its own account and not for the
account of others, or if the Investor is subscribing for the Shares as a fiduciary or agent for one or more investor accounts,
each owner of such account is a qualified institutional buyer, and the Investor has full investment discretion with respect to
each such account, and the full power and authority to make the acknowledgements, representations, warranties and agreements herein
on behalf of each owner of each such account, and (iii) is not acquiring the Shares with a view to, or for offer or sale in connection
with, any distribution of the Shares in any manner that would violate the Securities Act (and shall provide the requested information
set forth on Schedule A) or any securities laws of the United States or any other jurisdiction. The Investor is not an
entity formed for the specific purpose of acquiring the Shares. The Investor further acknowledges that it is aware that the sale
to it is being made in reliance on a private placement exemption from registration under the Securities Act and is acquiring the
Shares for its own account or for an account over which it exercises sole discretion for another qualified institutional buyer
or accredited investor.



    8 


     


    




 


b.       The
Investor (i) is an institutional account as defined in FINRA Rule 4512(c), (ii) is a sophisticated investor, experienced in investing
in private equity transactions and capable of evaluating investment risks independently, both in general and with regard to all
transactions and investment strategies involving a security or securities, including its participation in the purchase of the
Shares, and (iii) has exercised independent judgment in evaluating its participation in the purchase of the Shares. Accordingly,
the Investor understands that the offering meets (i) the exemptions from filing under FINRA Rule 5123(b)(1)(A) and (ii) the institutional
customer exemption under FINRA Rule 2111(b).


 


c.       The
Investor acknowledges and agrees that the Shares are being offered in a transaction not involving any public offering within the
meaning of the Securities Act and that the Shares have not been registered under the Securities Act or any other applicable securities
laws. The Investor acknowledges and agrees that the Shares are being offered for resale in transactions not requiring registration
under the Securities Act, and unless so registered, may not be offered, sold, pledged or otherwise transferred by the Investor
except in compliance with the registration requirements of the Securities Act or any other applicable securities laws, pursuant
to any exemption therefrom or in a transaction not subject thereto. The Investor acknowledges and agrees that the Shares will
not be immediately eligible for resale pursuant to Rule 144 promulgated under the Securities Act. The Investor acknowledges and
agrees that it has been advised to consult legal counsel prior to making any offer, resale, transfer, pledge or disposition of
any of the Shares.


 


d.       The
Investor acknowledges and agrees that the Investor is purchasing the Shares from VS PubCo. The Investor further acknowledges that
there have been no representations, warranties, covenants and agreements made to the Investor by or on behalf of Horizon, VS PubCo,
or any control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing or any other
person or entity, expressly or by implication, other than those representations, warranties, covenants and agreements of Horizon
and VS PubCo, as applicable, expressly set forth in Section 5 of this Subscription Agreement.


 


e.       The
Investor’s acquisition and holding of the Shares will not constitute or result in a non-exempt prohibited transaction under
Section 406 of the Employee Retirement Income Security Act of 1974, as amended, Section 4975 of the Internal Revenue Code of 1986,
as amended, or any applicable similar law.


 


f.       The
Investor acknowledges and agrees that the Investor has received such information as the Investor deems necessary in order to make
an investment decision with respect to the Shares, including, with respect to Horizon, VS PubCo, the Transaction and the business
of Vivid Seats LLC and its direct and indirect subsidiaries (together, the “Target”). Without limiting the
generality of the foregoing, the Investor acknowledges that he, she or it has reviewed the SEC Reports. The Investor acknowledges
and agrees that the Investor and the Investor’s professional advisor(s), if any, have had an opportunity to directly ask
such questions, receive such answers and obtain such information from Horizon and VS PubCo as the Investor and such Investor’s
professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the Shares.



    9 


     


    




 


g.       The
Investor became aware of this offering of the Shares solely by means of direct contact between the Investor and Horizon, VS PubCo
or a representative of Horizon or VS PubCo, and the Shares were offered to the Investor solely by direct contact between the Investor
and Horizon, VS PubCo or a representative of Horizon or VS PubCo. The Investor did not become aware of this offering of the Shares,
nor were the Shares offered to the Investor, by any other means. The Investor acknowledges that the Shares (i) were not offered
to it by any form of general solicitation or general advertising and (ii) are not being offered to it in a manner involving a
public offering under, or in a distribution in violation of, the Securities Act, or any state securities laws. The Investor acknowledges
that it is not relying upon, and has not relied upon, any statement, representation or warranty made by any person, firm or corporation
(including, without limitation, Horizon, VS PubCo, the Placement Agents, any of their respective affiliates or any control persons,
officers, directors, employees, partners, agents or representatives of any of the foregoing), other than the representations and
warranties of Horizon and VS PubCo, as applicable, contained in Section 5 of this Subscription Agreement, in making its investment
decision with respect to the Shares.


 


h.       The
Investor acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Shares,
including those set forth in Horizon’s and/or VS PubCo’s, as applicable, filings with the SEC. The Investor has such
knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment
in the Shares, and the Investor has sought such accounting, legal and tax advice as the Investor has considered necessary to make
an informed investment decision.


 


i.       Alone,
or together with any professional advisor(s), the Investor has analyzed and fully considered the risks of an investment in the
Shares and determined that the Shares are a suitable investment for the Investor and that the Investor is able at this time and
in the foreseeable future to bear the economic risk of a total loss of the Investor’s investment in the Shares. The Investor
acknowledges specifically that a possibility of total loss exists.


 


j.       The
Investor acknowledges that it is able to fend for itself in the transactions contemplated herein; has such knowledge and experience
in financial and business matters as to be capable of evaluating the merits and risks of its prospective investment in the Shares;
and has the ability to bear the economic risks of its prospective investment and can afford the complete loss of such investment.
None of the Placement Agents, any of their respective affiliates or any of them or their control persons, officers, directors
or employees shall have any liability to it or any account for which it is acquiring the Shares, in connection with any purchase
of the Shares.


 


k.       Except
for the representations, warranties and agreements of Horizon, VS PubCo or their respective affiliates expressly set forth in
any purchase agreement or similar document, the Investor is relying on its own sources of information, investment analysis and
due diligence (including professional advice it deems appropriate) with respect to the Transaction, the Shares and the business,
financial condition or results of operations of Horizon, VS PubCo or their respective affiliates, including but not limited to
all business, legal, regulatory, accounting, credit and tax matters. In making its decision to purchase the Shares, the Investor
has relied solely upon its own independent investigation of Horizon, VS PubCo, the Target, their respective affiliates, the Shares
and the offer and sale of the Shares. Without limiting the generality of the foregoing, the Investor has not relied on any statements
or other information provided by or on behalf of the Placement Agents or any of their respective affiliates or any control persons,
officers, directors, employees, partners, agents or representatives of any of the foregoing concerning Horizon, VS PubCo, the
Target, the Transaction, the Transaction Agreement, this Subscription Agreement or the transactions contemplated hereby or thereby,
the Shares or the offer and sale of the Shares. The Investor further acknowledges it has (i) had access to, and an adequate opportunity
to review and understand the materials and information made available to it in connection with the Transaction, including financial
and other information as it deems necessary to make its decision to purchase the Shares, and (ii) has made its own assessment
and satisfied itself concerning the relevant tax and other economic considerations relevant to its investment in the Shares.

l.       The
Investor acknowledges that no federal or state agency has passed upon or endorsed the merits of the offering of the Shares or
made any findings or determination as to the fairness of this investment.


 


m.       The
Investor, if not an individual, has been duly formed or incorporated and is validly existing and is in good standing under the
laws of its jurisdiction of formation or incorporation, with power and authority to enter into, deliver and perform its obligations
under this Subscription Agreement.


 


n.       The
execution, delivery and performance by the Investor of this Subscription Agreement are within the powers of the Investor, have
been duly authorized and will not constitute or result in a breach or default under or conflict with any order, ruling or regulation
of any court or other tribunal or of any governmental commission or agency, or any agreement or other undertaking, to which the
Investor is a party or by which the Investor is bound, and, if the Investor is not an individual, will not violate any provisions
of the Investor’s organizational documents, including, without limitation, its incorporation or formation papers, bylaws,
indenture of trust or partnership or operating agreement, as may be applicable. The signature on this Subscription Agreement is
genuine, and the signatory, if the Investor is an individual, has legal competence and capacity to execute the same or, if the
Investor is not an individual, the signatory has been duly authorized to execute the same, and, assuming that this Subscription
Agreement constitutes the valid and binding agreement of Horizon and VS PubCo, this Subscription Agreement constitutes a legal,
valid and binding obligation of the Investor, enforceable against the Investor in accordance with its terms except as may be limited
or otherwise affected by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other laws relating
to or affecting the rights of creditors generally or (ii) principles of equity, whether considered at law or equity.


 


o.       The
Investor is not (i) a person or entity named on the List of Specially Designated Nationals and Blocked Persons administered by
the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”)
or in any Executive Order issued by the President of the United States and administered by OFAC (“OFAC
List”), or a person or entity prohibited by any OFAC sanctions program, (ii) a Designated National as defined
in the Cuban Assets Control Regulations, 31 C.F.R. Part 515, or (iii) a non-U.S. shell bank or providing banking services indirectly
to a non-U.S. shell bank. The Investor agrees to provide law enforcement agencies, if requested thereby, such records as required
by applicable law, provided that the Investor is permitted to do so under applicable law. If the Investor is a financial
institution subject to the Bank Secrecy Act (31 U.S.C. Section 5311 et seq.) (the “BSA”),
as amended by the USA PATRIOT Act of 2001 (the “PATRIOT Act”), and
its implementing regulations (collectively, the “BSA/PATRIOT Act”),
the Investor maintains policies and procedures reasonably designed to comply with applicable obligations under the BSA/PATRIOT
Act. To the extent required, it maintains policies and procedures reasonably designed for the screening of its investors against
the OFAC sanctions programs, including the OFAC List. To the extent required by applicable law, the Investor maintains policies
and procedures reasonably designed to ensure that the funds held by the Investor and used to purchase the Shares were legally
derived.

q.       Neither
the Placement Agents, nor any of their respective affiliates, nor any control persons, officers, directors, employees, partners,
agents or representatives of any of the foregoing have made any independent investigation with respect to Horizon, VS PubCo, the

r.       The
Investor acknowledges that, in connection with the issue and purchase of the Shares, the Placement Agents have not acted as its
financial advisor or fiduciary. In addition, the Investor acknowledges and agrees that the Placement Agents have not provided
any recommendation or investment advice nor have the Placement Agents solicited any action from it with respect to the offer and
sale of the Shares and it has consulted with its own legal, accounting, financial, regulatory and tax advisors to the extent deemed
appropriate. The Investor further acknowledges and agrees that, although the Placement Agents may choose to provide certain Regulation
Best Interest and Form CRS disclosures or other documentation to it in connection with the offer and sale of the Shares, the Placement
Agents are not making a recommendation to participate in the offer and sale of the Shares, or to enter into any purchase agreement
or similar document, and nothing set forth in any such disclosure or documents that may be provided to it from time to time is
intended to suggest that the Placement Agents are making such a recommendation.


 


s.       The
Investor has or has commitments to have and, when required to deliver payment to VS PubCo pursuant to Section 2 above, will have,
sufficient funds to pay the Subscription Amount and consummate the purchase and sale of the Shares pursuant to this Subscription
Agreement.


 


t.       The
Investor acknowledges that the purchase and sale of Shares hereunder meets the exemptions from filing under FINRA Rule 5123(b)(1)(C)
or (J).



    12 


     


    




 


u.       The
Investor acknowledges that Placement Agents may have acquired, or during the term of this Subscription Agreement may acquire,
non-public information with respect to Horizon, VS PubCo, the Target or their respective affiliates, which the Investor agrees,
subject to requirements under applicable law, need not be provided to it.


 


v.       The
Investor hereby acknowledges and agrees that (a) Credit Suisse is acting solely as Placement Agent in connection with the Transaction
and is not acting as an underwriter or in any other capacity and is not and shall not be construed as a fiduciary for it, Horizon,
VS PubCo, their respective affiliates or any other person or entity in connection with the Transaction, (b) Credit Suisse has
not made and will not make any representation or warranty, whether express or implied, of any kind or character and has not provided

PubCo, the Target, their respective affiliates or the Transaction, and (d) Credit Suisse shall have no liability or obligation
(including without limitation, for or with respect to any losses, claims, damages, obligations, penalties, judgments, awards,
liabilities, costs, expenses or disbursements incurred by it, Horizon, VS PubCo, their respective affiliates or any other person
or entity), whether in contract, tort or otherwise, to it, or to any person claiming through it, in respect of the Transaction.


 


w.       The
Investor acknowledges that Evercore is acting both as placement agent in connection with the offer and sale of the Shares to be
issued pursuant to this Transaction and as financial advisor to the Target in connection with the business combination to which
the sale of the Shares relates, and that Evercore may receive fees both for its placement agent services and financial advisory
services. The Investor also acknowledges and agrees that (a) Evercore is not acting as an underwriter and is not and shall not
be construed as a fiduciary for it, Horizon, VS PubCo, their respective affiliates or any other person or entity in connection
with the Transaction; provided, however, that Evercore is acting as a financial advisor to the Target, (b) Evercore has not made
and will not make any representation or warranty, whether express or implied, of any kind or character and have not provided any
advice or recommendation in connection with the Transaction, (c) Evercore will have no responsibility with respect to (i) any

whether in contract, tort or otherwise, to it, or to any person claiming through it, in respect of the Transaction.

		7.	Registration
Rights.



 


a.       In
the event that the Shares are not registered in connection with the consummation of the Transaction, VS PubCo agrees that, within
thirty (30) calendar days after the consummation of the Transaction (the “Filing Deadline”),
it will file with the SEC (at its sole cost and expense) a registration statement registering the resale of the Shares (the “Registration
Statement”), and it shall use its commercially reasonable efforts to have the Registration Statement declared
effective as soon as practicable after the filing thereof, but no later than the earlier of (i) ninety (90) calendar days after
the filing thereof (or one hundred and twenty (120) calendar days after the filing thereof if the SEC notifies VS PubCo that it
will “review” the Registration Statement) and (ii) ten (10) business days after VS PubCo is notified (orally or in
writing, whichever is earlier) by the SEC that the Registration Statement will not be “reviewed” or will not be subject
to further review (such date, the “Effectiveness Date”). VS PubCo
agrees to cause such Registration Statement, or another shelf registration statement that includes the Shares to be sold pursuant
to this Subscription Agreement, to remain effective until the earliest of (i) the second anniversary of the date the initial Registration
Statement filed hereunder is declared effective, (ii) the date on which the Investor ceases to hold any Shares issued pursuant
to this Subscription Agreement, or (iii) the date on which the Investor is able to sell all of its Shares issued pursuant to this
Subscription Agreement (or shares received in exchange therefor) under Rule 144 of the Securities Act within ninety (90) days
without limitation as to the amount of such securities that may be sold and without the requirement for VS PubCo to be in compliance
with the current public information requirement under Rule 144(c) (or Rule 144(i)(2), if applicable) (the earliest of (i)–(iii)
being the “Expiration”). The Investor agrees to disclose its ownership
to VS PubCo upon request to assist it in making the determination described above. The Investor acknowledges and agrees that VS
PubCo may suspend the use of any such registration statement if it determines in good faith that, in order for such registration
statement not to contain a material misstatement or omission, an amendment thereto would be needed to include information that
would at that time not otherwise be required in a current, quarterly, or annual report under the Exchange Act, provided,
that (A) VS PubCo shall not so delay filing or so suspend the use of the Registration Statement for a period of more than sixty
(60) consecutive days or more than a total of one hundred and twenty (120) calendar days, in each case in any three hundred sixty
(360) day period, and (B) VS PubCo shall use commercially reasonable efforts to make such registration statement available for
the sale by the Investor of such securities as soon as practicable thereafter. VS PubCo’s obligations to include the Shares
issued pursuant to this Subscription Agreement (or shares issued in exchange therefor) for resale in the Registration Statement
are contingent upon the Investor furnishing in writing to VS PubCo such information regarding the Investor, the securities of
VS PubCo held by the Investor and the intended method of disposition of such Shares, which shall be limited to non-underwritten
public offerings, as shall be reasonably requested by VS PubCo to effect the registration of such Shares, and shall execute such
documents in connection with such registration as VS PubCo may reasonably request that are customary of a selling stockholder
in similar situations, provided, however, that the Investor shall not in connection with the foregoing be required
to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer
the Shares. VS PubCo will provide a draft of the Registration Statement to the Investor for review at least two (2) business days
in advance of filing the Registration Statement. So long as the Investor delivers to VS PubCo a completed questionnaire (which
shall include representations and warranties as to relevant matters), the Investor shall not be identified as a statutory underwriter
in the Registration Statement unless in response to a comment or request from the staff of the SEC or another regulatory agency;
provided, however, that if the SEC requests that the Investor be identified as a statutory underwriter in the Registration
Statement, the Investor will have an opportunity to withdraw from the Registration Statement. Notwithstanding the foregoing, if
the SEC prevents VS PubCo from including any or all of the Shares proposed to be registered under the Registration Statement due
to limitations on the use of Rule 415 of the Securities Act for the resale of the Shares by the applicable shareholders or otherwise,
such Registration Statement shall register for resale such number of Shares which is equal to the maximum number of Shares as
is permitted by the SEC. In such event, the number of Shares to be registered for each selling shareholder named in the Registration
Statement shall be reduced pro rata among all such selling shareholders and as promptly as practicable after being permitted to
register additional Shares under Rule 415 under the Securities Act, VS PubCo shall file a new Registration Statement to register
such Shares not included in the initial Registration Statement and cause such Registration Statement to become effective as promptly
as practicable consistent with the terms of this Section 7. For purposes of clarification, any failure by VS PubCo to file the
Registration Statement by the Filing Deadline or to effect such Registration Statement by the Effectiveness Date shall not otherwise
relieve VS PubCo of its obligations to file or effect the Registration Statement set forth in this Section 7. For purposes of
this Section 7, “Shares” shall mean, as of any date of determination, the Shares acquired by the Investor pursuant
to this Subscription Agreement and any other equity security issued or issuable with respect to such Shares by way of stock split,
dividend, distribution, recapitalization, merger, exchange, replacement or similar event, and “Investor” shall include
any affiliate of the undersigned Investor to which the rights under this Section 7 have been duly assigned.



    14 


     


    




 


b.       Prior
to the Expiration, VS PubCo shall advise the Investor within three (3) business days (at VS PubCo’s expense): (i) when a
Registration Statement or any post-effective amendment thereto has become effective; (ii) of the issuance by the SEC of any stop
order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose; (iii)
of the receipt by VS PubCo of any notification with respect to the suspension of the qualification of the Shares included therein
for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and (iv) subject to the provisions
in this Subscription Agreement, of the occurrence of any event that requires the making of any changes in any Registration Statement
or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required
to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances
under which they were made) not misleading (provided that any such notice pursuant to this Section 7(b)(iv) shall solely
provide that the use of the Registration Statement or prospectus has been suspended without setting forth the reason for such
suspension). VS PubCo shall use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness
of any Registration Statement as soon as reasonably practicable. Upon the occurrence of any event contemplated in clauses (i)
through (iv) above, except for such times as VS PubCo is permitted hereunder to suspend, and has suspended, the use of a prospectus
forming part of a registration statement, VS PubCo shall use its commercially reasonable efforts to as soon as reasonably practicable
prepare a post-effective amendment to such registration statement or a supplement to the related prospectus, or file any other
required document so that, as thereafter delivered to purchasers of the Shares included therein, such prospectus will not include
any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading. The Investor agrees that it will immediately discontinue offers
and sales of the Shares using a Registration Statement until the Investor receives copies of a supplemental or amended prospectus
that corrects the misstatement(s) or omission(s) referred to above in clause (iv) and receives notice that any post-effective
amendment has become effective or unless otherwise notified by VS PubCo that it may resume such offers and sales. If so directed
by VS PubCo, the Investor will deliver to VS PubCo or, in the Investor’s sole discretion destroy, all copies of the prospectus
covering the Shares in the Investor’s possession; provided, however, that this obligation to deliver or destroy
all copies of the prospectus covering the Shares shall not apply (x) to the extent the Investor is required to retain a copy of
such prospectus in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or in accordance
with a bona fide pre-existing document retention policy or (y) to copies stored electronically on archival servers as a result
of automatic data back-up.



    15 


     


    




 


c.       Prior
to the Expiration, VS PubCo will use commercially reasonable efforts to file all reports necessary to enable the undersigned to
resell the Shares pursuant to the Registration Statement. For as long as the Investor holds Shares, VS PubCo will use commercially
reasonable efforts to file all reports necessary to enable the undersigned to resell the Shares pursuant to Rule 144 of the Securities
Act (when Rule 144 of the Securities Act becomes available to the Investor). In addition, in connection with any sale, assignment,
transfer or other disposition of the Shares by the Investor pursuant to Rule 144 or pursuant to any other exemption under the
Securities Act such that the Shares held by the Investor become freely tradable and upon compliance by the Investor with the requirements
of this Section 7(c), if requested by the Investor, VS PubCo shall cause the transfer agent for the Shares (the “Transfer
Agent”) to remove any restrictive legends related to the book entry account holding such Shares and make a new,
unlegended entry for such book entry Shares sold or disposed of without restrictive legends within three (3) trading days of any
such request therefor from the Investor, provided that VS PubCo and the Transfer Agent have timely received from the Investor
customary representations and other documentation reasonably acceptable to VS PubCo and the Transfer Agent in connection therewith.
Subject to receipt from the Investor by VS PubCo and the Transfer Agent of customary representations and other documentation reasonably
acceptable to VS PubCo and the Transfer Agent in connection therewith, the Investor may request that VS PubCo remove any legend
from the book entry position evidencing its Shares and VS PubCo will, if required by the Transfer Agent, cause an opinion of VS
PubCo’s counsel be provided, in a form reasonably acceptable to the Transfer Agent, to the effect that the removal of such
restrictive legends in such circumstances may be effected under the Securities Act, following the earliest of such time as such
Shares (i) (x) are subject to or (y) have been or are about to be sold or transferred pursuant to an effective registration statement,
(ii) have been or are about to be sold pursuant to Rule 144, or (iii) are eligible for resale under Rule 144(b)(1) or any successor
provision without the requirement for VS PubCo to be in compliance with the current public information requirement under Rule
144 and without volume or manner-of-sale restrictions applicable to the sale or transfer of such Shares. If restrictive legends
are no longer required for such Shares pursuant to the foregoing, VS PubCo shall, in accordance with the provisions of this section
and within three (3) trading days of any request therefor from the Investor accompanied by such customary and reasonably acceptable
representations and other documentation referred to above establishing that restrictive legends are no longer required, deliver
to the Transfer Agent irrevocable instructions that the Transfer Agent shall make a new, unlegended entry for such book entry
Shares. VS PubCo shall be responsible for the fees of its Transfer Agent, its legal counsel and all DTC fees associated with such
issuance.



    16 


     


    




 


		d.	Indemnification.



 


(i)       VS
PubCo agrees to indemnify and hold harmless, to the extent permitted by law, the Investor, its directors, officers, employees,
investment advisers and agents, and each person who controls the Investor (within the meaning of the Securities Act or the Exchange
Act) and each affiliate of the Investor (within the meaning of Rule 405 under the Securities Act) from and against any and all
losses, claims, damages, liabilities and expenses (including, without limitation, any reasonable attorneys’ fees and expenses
incurred in connection with defending or investigating any such action or claim) caused by any untrue or alleged untrue statement
of material fact contained in any Registration Statement, prospectus included in any Registration Statement or preliminary prospectus
or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein
or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information
furnished in writing to VS PubCo by or on behalf of the Investor expressly for use therein.


 


(ii)      The
Investor agrees, severally and not jointly with any person that is a party to the Other Subscription Agreements or any other selling
shareholder under the Registration Statement, to indemnify and hold harmless VS PubCo, its directors and officers and agents and
each person who controls VS PubCo (within the meaning of the Securities Act) against any losses, claims, damages, liabilities
and expenses (including, without limitation, reasonable attorneys’ fees) resulting from any untrue statement of material
fact contained in the Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto
or any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but
only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing
by the Investor expressly for use therein. In no event shall the liability of the Investor be greater in amount than the dollar
amount of the net proceeds received by the Investor upon the sale of the Shares purchased pursuant to this Subscription Agreement
giving rise to such indemnification obligation.


 


(iii)     Any
person entitled to indemnification herein shall (1) give prompt written notice to the indemnifying party of any claim with respect
to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s
right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (2) permit such indemnifying
party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed,
the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent.
An indemnifying party who elects not to assume the defense of a claim shall not be obligated to pay the fees and expenses of more
than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment
of legal counsel to any indemnified party a conflict of interest exists between such indemnified party and any other of such indemnified
parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the
entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money
is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such
claim or litigation.



    17 


     


    




 


(iv)      The
indemnification provided for under this Subscription Agreement shall remain in full force and effect regardless of any investigation
made by or on behalf of the indemnified party or any officer, director, employee, agent, affiliate or controlling person of such
indemnified party and shall survive the transfer of the Shares purchased pursuant to this Subscription Agreement.


 


(v)       If
the indemnification provided under this Section 7(d) from the indemnifying party is unavailable or insufficient to hold harmless
an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying
party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party
as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative
fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative
fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action
in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material
fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s
and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action.
The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include,
subject to the limitations set forth above, any legal or other fees, charges or expenses reasonably incurred by such party in
connection with any investigation or proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 7(d) from any person who was not guilty
of such fraudulent misrepresentation. In no event shall the liability of the Investor be greater in amount than the dollar amount
of the net proceeds received by the Investor upon the sale of the Shares purchased pursuant to this Subscription Agreement giving
rise to such contribution obligation.


 


8.       Termination.
This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of
the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earlier
to occur of (a) such date and time as the Transaction Agreement is terminated in accordance with its terms without being consummated,
(b) upon the mutual written agreement of each of the parties hereto and VS PubCo to terminate this Subscription Agreement, (c)
on or after the Agreement End Date (as defined in the Transaction Agreement as the same exists on the date of this Subscription
Agreement), if the Closing has not occurred by such date, or (d) if any of the conditions to Closing set forth in Section 3 of
this Subscription Agreement are not satisfied or waived, or are not capable of being satisfied, on or prior to the Closing and,
as a result thereof, the transactions contemplated by this Subscription Agreement will not be and are not consummated at the Closing
(the termination events described in clauses (a)–(d) above, collectively, the “Termination
Events”); provided that nothing herein will relieve any party from liability for any willful breach hereof
prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities
or damages arising from any such willful breach. Horizon shall notify the Investor in writing of the termination of the Transaction
Agreement promptly after the termination of such agreement. Upon the occurrence of any Termination Event, this Subscription Agreement
shall be void and of no further effect and any monies paid by the Investor to VS PubCo in connection herewith shall promptly (and
in any event within one (1) business day) following the Termination Event be returned to the Investor.



    18 


     


    




 


9.           Trust
Account Waiver. The Investor acknowledges that Horizon is a blank check company with the powers and privileges to effect
a merger, asset acquisition, reorganization or similar business combination involving Horizon and one or more businesses or assets.
The Investor further acknowledges that, as described in Horizon’s prospectus relating to its initial public offering dated
August 20, 2020 (the “Prospectus”) available at www.sec.gov, substantially
all of Horizon’s assets consist of the cash proceeds of Horizon’s initial public offering and private placement of
its securities, and substantially all of those proceeds have been deposited in a trust account (the “Trust
Account”) for the benefit of Horizon, its public shareholders and the underwriters of Horizon’s initial
public offering. Except with respect to interest earned on the funds held in the Trust Account that may be released to Horizon
to pay its tax obligations, if any, the cash in the Trust Account may be disbursed only for the purposes set forth in the Prospectus.
For and in consideration of Horizon entering into this Subscription Agreement, the receipt and sufficiency of which are hereby
acknowledged, the Investor hereby irrevocably waives any and all right, title and interest, or any claim of any kind it has or
may have in the future, in or to any monies held in the Trust Account, and agrees not to seek recourse against the Trust Account
as a result of, or arising out of, this Subscription Agreement; provided, however, that nothing in this Section
9 shall be deemed to limit the Investor’s right, title, interest or claim to any monies held in the Trust Account by virtue
of its record or beneficial ownership of any Class A Shares, pursuant to a validly exercised redemption right with respect to
any such Class A Shares.


 


10.         Miscellaneous.


 


a.       Neither
this Subscription Agreement nor any rights that may accrue to the Investor hereunder (other than the Shares acquired hereunder,
if any) may be transferred or assigned; provided that the Investor may assign its rights and obligations under this Subscription
Agreement to one or more of its affiliates (including other investment funds or accounts managed or advised by the investment
manager who acts on behalf of the Investor or an affiliate thereof); provided, that no such assignment shall relieve the
Investor of its obligations hereunder.


 


b.       Horizon
and VS PubCo may request from the Investor such additional information as Horizon and/or VS PubCo may deem necessary to register
the resale of the Shares and evaluate the eligibility of the Investor to acquire the Shares, and the Investor shall provide such
information as may reasonably be requested, to the extent readily available and to the extent consistent with the Investor’s
internal policies and procedures; provided that each of Horizon and VS PubCo agrees to keep any such information provided
by the Investor confidential except (i) as required by the federal securities law or pursuant to other routine proceedings of
regulatory authorities or (ii) to the extent such disclosure is required by law, at the request of the staff of the SEC or regulatory
agency or under the regulations of any national securities exchange on which Horizon’s or VS PubCo’s, as applicable
securities are listed for trading. The Investor acknowledges and agrees that if it does not provide VS PubCo with such requested
information, VS PubCo may not be able to register the Investor’s Shares for resale pursuant to Section 7 hereof. The Investor
acknowledges that Horizon and/or VS PubCo may file a form of this Subscription Agreement that does not identify the Investor with
the SEC as an exhibit to a periodic report or a registration statement of Horizon and/or VS PubCo.



    19 


     


    




 


c.       The
Investor acknowledges that Horizon and VS PubCo will rely on the acknowledgments, understandings, agreements, representations
and warranties contained in Section 6 of this Subscription Agreement. Prior to the Closing, each party hereto agrees to promptly
notify the other parties hereto and the Placement Agents if any of their respective acknowledgments, understandings, agreements,
representations and warranties set forth in Section 5 or Section 6, as applicable, above are no longer accurate in any material
respect (other than those acknowledgments, understandings, agreements, representations and warranties qualified by materiality,
in which case such party shall notify the other parties and the Placement Agents if they are no longer accurate in any respect).


 


d.       Horizon,
VS PubCo and the Placement Agents (each as a third party beneficiary with right of enforcement as set forth in this Subscription
Agreement) are each irrevocably authorized to produce this Subscription Agreement or a copy hereof to any interested party in
any administrative or legal proceeding or official inquiry with respect to the matters covered hereby; provided, however,
that the foregoing clause of this Section 10(d) shall not give the Placement Agents any rights other than those expressly set
forth herein and, without limiting the generality of the foregoing and for the avoidance of doubt, in no event shall the Target
be entitled to rely on any of the representations and warranties of Horizon set forth in this Subscription Agreement.


 


e.       The
Investor hereby acknowledges and agrees that it will not, nor will any person acting at the Investor’s direction or pursuant
to any understanding with Investor (including Investor’s controlled affiliates), directly or indirectly, offer, sell, pledge,
contract to sell, sell any option in, or engage in hedging activities or execute any “short sales” (as defined in
Rule 200 of Regulation SHO under the Exchange Act) with respect to, any Shares or any securities of Horizon or any instrument
exchangeable for or convertible into any Shares or any securities of Horizon until the consummation of the Transaction (or such
earlier termination of this Subscription Agreement in accordance with its terms). For the avoidance of doubt, this Section 10(e)
shall not apply to any sale (including the exercise of any redemption right) of securities of Horizon (i) held by the Investor,
its controlled affiliates or any person or entity acting on behalf of the Investor or any of its controlled affiliates prior to
the execution of this Subscription Agreement or (ii) purchased by the Investor, its controlled affiliates or any person or entity
acting on behalf of the Investor or any of its controlled affiliates in open market transactions after the execution of this Subscription
Agreement. Notwithstanding the foregoing, (i) nothing herein shall prohibit any entities under common management with the Investor
that have no knowledge of this Subscription Agreement or of the Investor’s participation in the transactions contemplated
hereby (including the Investor’s controlled affiliates and/or affiliates) from entering into any short sales; (ii) in the
case of an Investor that is a multimanaged investment vehicle whereby separate portfolio managers manage separate portions of
such Investor’s assets and the portfolio managers have no knowledge of the investment decisions made by the portfolio managers
managing other portions of such Investor’s assets, this Section 10(e) shall only apply with respect to the portion of assets
managed by the portfolio manager that made the investment decision to purchase the Shares covered by this Subscription Agreement.


 


f.       All
of the agreements, representations and warranties made by each party hereto in this Subscription Agreement shall survive the Closing.
For the avoidance of doubt, if for any reason the Closing does not occur prior to the consummation of the Transaction, all representations,
warranties, covenants and agreements of the parties hereunder shall survive the consummation of the Transaction and remain in
full force and effect.



    20 


     


    




 


g.       This
Subscription Agreement may not be modified, waived or terminated (other than pursuant to the terms of Section 8 above) except
by an instrument in writing, signed by each of the parties hereto. No failure or delay of any party in exercising any right or
remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such right or power, or any course of conduct, preclude any other or further
exercise thereof or the exercise of any other right or power. The rights and remedies of the parties hereunder are cumulative
and are not exclusive of any rights or remedies that they would otherwise have hereunder.


 


h.       This
Subscription Agreement (including the schedule hereto) constitutes the entire agreement, and supersedes all other prior agreements,
understandings, representations and warranties, both written and oral, among the parties, with respect to the subject matter hereof.
Except as set forth in Section 7(d), Section 10(d), this Section 10(h), the last two sentences of Section 10(l) and Section 11
with respect to the persons specifically referenced therein, this Subscription Agreement shall not confer any rights or remedies
upon any person other than the parties hereto, and their respective successor and assigns, and the parties hereto acknowledge
that such persons so referenced are third party beneficiaries of this Subscription Agreement with right of enforcement for the
purposes of, and to the extent of, the rights granted to them, if any, pursuant to the applicable provisions.


 


i.       Except
as otherwise provided herein, this Subscription Agreement shall be binding upon, and inure to the benefit of the parties hereto
and their heirs, executors, administrators, successors, legal representatives, and permitted assigns, and the agreements, representations,
warranties, covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon, such heirs, executors,
administrators, successors, legal representatives and permitted assigns.


 


j.       If
any provision of this Subscription Agreement shall be adjudicated by a court of competent jurisdiction to be invalid, illegal
or unenforceable, the validity, legality or enforceability of the remaining provisions of this Subscription Agreement shall not
in any way be affected or impaired thereby and shall continue in full force and effect.


 


k.       This
Subscription Agreement may be executed in one or more counterparts (including by facsimile or electronic mail or in .pdf) and
by different parties in separate counterparts, with the same effect as if all parties hereto had signed the same document. All
counterparts so executed and delivered shall be construed together and shall constitute one and the same agreement.


 


l.       The
parties hereto acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Subscription
Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that
the parties shall be entitled to an injunction or injunctions to prevent breaches of this Subscription Agreement, without posting
a bond or undertaking and without proof of damages, to enforce specifically the terms and provisions of this Subscription Agreement,
this being in addition to any other remedy to which such party is entitled at law, in equity, in contract, in tort or otherwise.
The parties hereto acknowledge and agree that the Placement Agents shall be entitled to rely on the provisions of the Subscription
Agreement of which the Placement Agents are each an express third party beneficiary, in each case, on the terms and subject to
the conditions set forth herein. For the avoidance of doubt, each of the Placement Agents are third party beneficiaries with rights
to enforce Section 5, Section 6, Section 10 and Section 11 hereof on their own behalf and not on behalf of Horizon or VS PubCo.



    21 


     


    




 


m.       If
any change in the number, type or classes of authorized shares of VS PubCo (including the Shares), other than as contemplated
by the Transaction Agreement or any agreement contemplated by the Transaction Agreement, shall occur between the date hereof and
immediately prior to the Closing by reason of reclassification, recapitalization, stock split (including reverse stock split)
or combination, exchange or readjustment of shares, or any stock dividend, the number of Shares issued to the Investor and Per
Share Purchase Price shall be appropriately adjusted to reflect such change.


 


n.       This
Subscription Agreement shall be governed by and construed in accordance with the laws of the State of New York (regardless of
the laws that might otherwise govern under applicable principles of conflicts of laws thereof) as to all matters (including any
action, suit, litigation, arbitration, mediation, claim, charge, complaint, inquiry, proceeding, hearing, audit, investigation
or reviews by or before any governmental entity related hereto), including matters of validity, construction, effect, performance
and remedies.


 


o.       THE
PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT
OF NEW YORK AND THE SUPREME COURT OF THE STATE OF NEW YORK SOLELY IN RESPECT OF THE INTERPRETATION AND ENFORCEMENT OF THE PROVISIONS

10(p) OF THIS SUBSCRIPTION AGREEMENT OR IN SUCH OTHER MANNER AS MAY BE PERMITTED BY LAW SHALL BE VALID AND SUFFICIENT SERVICE
THEREOF.



    22 


     


    




 


EACH
PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED
HEREBY IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY

RELATING TO THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS SUBSCRIPTION AGREEMENT. EACH PARTY CERTIFIES

11.         Non-Reliance
and Exculpation. The Investor acknowledges that it is not relying upon, and has not relied upon, any statement, representation,
warranty or other information made or provided by any person, firm or corporation (including, without limitation, the Placement
Agents, any of their respective affiliates or any control persons, officers, directors, employees, partners, agents or representatives
of any of the foregoing), other than the statements, representations and warranties of Horizon and VS PubCo, as applicable, expressly
contained in Section 5 of this Subscription Agreement, in making its investment or decision to invest in VS PubCo. The Investor
acknowledges and agrees that, other than the statements, representations and warranties of Horizon and VS PubCo, as applicable,
expressly contained in Section 5 of this Subscription Agreement, none of (i) any other investor pursuant to this Subscription
Agreement or any other subscription agreement related to the private placement of the Shares (including the investor’s respective
affiliates or any control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing)
or (ii) the Placement Agents, their respective affiliates or any control persons, officers, directors, employees, partners, agents
or representatives of any of the foregoing shall have any liability to the Investor, or to any other investor, pursuant to, arising
out of or relating to this Subscription Agreement or any other subscription agreement related to the private placement of the
Shares, the negotiation hereof or thereof or its subject matter, or the transactions contemplated hereby or thereby, including,
without limitation, with respect to any action heretofore or hereafter taken or omitted to be taken by any of them in connection
with the purchase of the Shares or with respect to any claim (whether in tort, contract or otherwise) for breach of this Subscription
Agreement or in respect of any written or oral representations made or alleged to be made in connection herewith, as expressly
provided herein, or for any actual or alleged inaccuracies, misstatements or omissions with respect to any information or materials
of any kind furnished by Horizon, VS PubCo, the Target, the Placement Agents or any Non-Party Affiliate concerning Horizon, VS
PubCo, the Target, the Placement Agents, any of their respective controlled affiliates, this Subscription Agreement or the transactions
contemplated hereby. For purposes of this Subscription Agreement, “Non-Party Affiliates” means each former, current
or future officer, director, employee, partner, member, manager, direct or indirect equityholder or affiliate of Horizon, VS PubCo,
the Placement Agents or any of Horizon’s, VS PubCo’s or the Placement Agents’ respective controlled affiliates
or any family member of the foregoing.



    23 


     


    




 


12.       Disclosure.
Horizon shall, by 9:00 a.m., New York City time, on the first (1st) business day immediately following the date of this Subscription
Agreement, issue one or more press releases or file with the SEC a Current Report on Form 8-K (collectively, the “Disclosure
Document”) disclosing all material terms of the transactions contemplated hereby and by the Other Subscription
Agreements, the Sponsor Support Agreement, the Exchange Agreement, the Transaction and any other material, nonpublic information
that Horizon has provided to the Investor at any time prior to the filing of the Disclosure Document. Upon the issuance of the
Disclosure Document, to the actual knowledge of Horizon, the Investor shall not be in possession of any material, non-public information
received from Horizon or any of its officers, directors, or employees or agents, and the Investor shall no longer be subject to
any confidentiality or similar obligations under any current agreement, whether written or oral, with Horizon, the Placement Agents
or any of their respective affiliates, relating to the transactions contemplated by this Subscription Agreement. Notwithstanding
anything in this Subscription Agreement to the contrary, Horizon shall not, without the prior written consent of the Investor,
publicly disclose the name of the Investor, its investment advisor or any of their respective affiliates or advisers, or include
the name of the Investor, its investment advisor or any of their respective affiliates or advisers (i) in any press release or
marketing materials or (ii) in any filing with the SEC or any regulatory agency or trading market, except (A) as required by the
federal securities law or pursuant to other routine proceedings of regulatory authorities or (B) to the extent such disclosure
is required by law, at the request of the staff of the SEC or regulatory agency or under the regulations of any national securities
exchange on which Horizon’s and/or VS PubCo’s securities are listed for trading, provided, that in the case of this
clause (ii), Horizon and/or VS PubCo shall provide Investor with prior written notice (including by e-mail) of such permitted
disclosure, and shall reasonably consult with Investor regarding such disclosure.


 


13.       Separate
Obligations. For the avoidance of doubt, all obligations of the Investor hereunder are separate and several from the obligations
of any Other Investor. The decision of Investor to purchase the Shares pursuant to this Subscription Agreement has been made by
Investor independently of any Other Investor or any other investor and independently of any information, materials, statements
or opinions as to the business, financial condition or results of operations of Horizon, VS PubCo, Target, or any of their respective
subsidiaries which may have been made or given by any Other Investor or by any agent or employee of any Other Investor, and neither
Investor nor any of its agents or employees shall have any liability to any Other Investor (or any other person) relating to or
arising from any such information, materials, statements or opinions. Nothing contained herein or in any Other Subscription Agreement,
and no action taken by Investor or Other Investors pursuant hereto or thereto, shall be deemed to constitute Investor and Other
Investor as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that Investor
and Other Investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated
by this Subscription Agreement and the Other Subscription Agreements. The Investor acknowledges that no Other Investor has acted
as agent for Investor in connection with making its investment hereunder and no Other Investor will be acting as agent of Investor
in connection with monitoring its investment in the Shares or enforcing its rights under this Subscription Agreement. The Investor
shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this
Subscription Agreement, and it shall not be necessary for any Other Investor to be joined as an additional party in any proceeding
for such purpose.



    24 


     


    




 


14.       Massachusetts
Business Trust. If Investor is a Massachusetts Business Trust, a copy of the Declaration of Trust of Investor or any affiliate
thereof is on file with the Secretary of State of the Commonwealth of Massachusetts and notice is hereby given that the Subscription
Agreement is executed on behalf of the trustees of Investor or any affiliate thereof as trustees and not individually and that
the obligations of the Subscription Agreement are not binding on any of the trustees, officers or stockholders of Investor or
any affiliate thereof individually but are binding only upon Investor or any affiliate thereof and its assets and property.
