The execution and delivery by Horizon of each Transaction Document and the consummation by Horizon of the Subscription and the Transaction have been duly and validly authorized by all necessary corporate action on the part of Horizon and, subject to receipt of the Company Shareholder Approval, no other proceedings on the part of Horizon (or any of its equityholders) are necessary to authorize the Transaction Documents or to consummate the Subscription and Transaction. Each Transaction Document has been duly and validly executed and delivered by Horizon and, assuming the due authorization, execution and delivery hereof and thereof by the applicable counterparties, constitutes the legal and binding obligations of Horizon, enforceable against Horizon in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and similar laws affecting the rights of creditors generally and by principles of equity, whether considered at law or equity.

(c) Except for such matters as would not reasonably be expected to have a Horizon Material Adverse Effect, there is no (i) suit, action, claim or other proceeding or arbitration before a governmental authority or arbitrator pending, or, to the knowledge of Horizon, threatened in writing against Horizon or any of its subsidiaries or (ii) judgment, decree, injunction, ruling or order of any governmental authority or arbitrator outstanding against Horizon or any of its subsidiaries, in each case relating to the Subscription, Transaction, or the Transaction Documents.

(d) Neither Horizon, nor, to Horizon’s knowledge, any person acting on its behalf has, directly or indirectly, made any offers or sales of any Horizon security or solicited any offers to buy any security under circumstances that would adversely affect reliance by Holdco on Section 4(a)(2) of the Securities Act for the exemption from registration for the transactions contemplated hereby or would require registration of the issuance of the Subscribed Shares pursuant to this Subscription Agreement under the Securities Act.

(e) Neither Horizon nor any person acting on its behalf has engaged or will engage in any form of general solicitation or general advertising (within the meaning of Regulation D under the Securities Act) in connection with any offer or sale of the Subscribed Shares, and neither Horizon nor, to Horizon’s knowledge, any person acting on its behalf has offered any of the Subscribed Shares in a manner involving a public offering under, or in a distribution in violation of, the Securities Act or any state securities laws.

12

(f) Except for the Placement Agent, no broker, investment banker, finder or other person is entitled to any brokerage or finder’s fee or commission solely in connection with the sale of the Subscribed Shares to Subscriber.

(h) Horizon is not controlled by or acting on behalf of (in connection with this Subscription) a person or entity resident that: (i) has been designated as non-cooperative with international anti-money laundering or counter terrorist financing principles or procedures, including the Money Laundering Control Act of 1986, 18 U.S.C. §§ 1956, 1957, and any other equivalent or comparable Laws of other countries; (ii) is the subject of an advisory issued by the Financial Crimes Enforcement Network of the U.S. Department of the Treasury; or (iii) has been designated by the Secretary of the Treasury under Section 311 of the USA PATRIOT Act as a Non-cooperative Jurisdiction, or an entity or individual that resides or has a place of business in, or is organized under the laws of, a Non-cooperative Jurisdiction.

(i) Horizon is in compliance with all applicable laws, except where such non-compliance would not be reasonably likely to have, individually or in the aggregate, a Horizon Material Adverse Effect. Since January 1, 2023, 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 Horizon Material Adverse Effect.

(j) Neither Horizon nor any of its controlled affiliates (i) is, or will be at or immediately after the Closing, a Covered Person, (ii) directly or indirectly hold, or will hold at or immediately after the Closing, a board seat on, a voting or equity interest in, or any contractual power to direct or cause the direction of the management or policies of, any Covered Person, or (iii) is engaged, or has plans to engage, or will be engaged at or immediately after the Closing, directly or indirectly, in a “covered activity,” as such term is defined in 31 C.F.R. § 850.208.

13

(c) The execution, delivery and performance by Subscriber of this Subscription Agreement, the subscription for the Subscribed Shares and the compliance by Subscriber 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 Subscriber pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which Subscriber is a party or by which Subscriber is bound or to which any of the property or assets of Subscriber is subject; (ii) the organizational documents of Subscriber; or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over Subscriber or any of its properties that, in the case of clauses (i) and (iii), would reasonably be expected to have a Subscriber Material Adverse Effect. For purposes of this Subscription Agreement, a “Subscriber Material Adverse Effect” means an event, change, development, occurrence, condition or effect with respect to Subscriber that would reasonably be expected to have a material adverse effect on Subscriber’s ability to consummate the transactions contemplated hereby, including the subscription for the Subscribed Shares.

(e) Subscriber understands that the Subscribed Shares are being offered in a transaction not involving any public offering within the meaning of the Securities Act and that the Subscribed Shares have not been registered under the Securities Act and that Holdco is not required to register the Subscribed Shares except as set forth in Section 7 of this Subscription Agreement. Subscriber understands that the Subscribed Shares will be “restricted securities” within the meaning of the Securities Act and may not be offered, resold, transferred, pledged or otherwise disposed of by Subscriber absent an effective registration statement under the Securities Act, except (i) to Holdco or a subsidiary thereof, or (ii) pursuant to an applicable exemption from the registration requirements of the Securities Act (including, without limitation, a private resale pursuant to so-called rule 4(a) 1 1/2 of the Securities Act), and, in each of cases (i) and (ii), in accordance with any applicable securities laws of the applicable states and other jurisdictions of the United States, and that any certificates or account entries representing the Subscribed Shares shall contain the restrictive legend set forth in Section 6(u).

Subscriber acknowledges and agrees that the Subscribed Shares will not be eligible for offer, resale, transfer, pledge or disposition pursuant to Rule 144 promulgated under the Securities Act (“Rule 144”), absent a change in law, receipt of regulatory no-action relief or an exemption, until at least one year from the filing of “Form 10” information with the Commission after the Closing Date.

Subscriber acknowledges that certain information provided by Holdco or by or on behalf of Horizon was based on projections prepared by Horizon and such projections were prepared based on assumptions and estimates that are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the projections.

(g) In making its decision to subscribe for the Subscribed Shares, Subscriber has relied solely upon independent investigation made by Subscriber and on the representations contained in this Subscription Agreement. Subscriber acknowledges and agrees that Subscriber has received or had access to, and had an adequate opportunity to review, such information as Subscriber deems necessary in order to make an investment decision with respect to the Subscribed Shares, including with respect to the SPAC, Horizon, Holdco and their respective subsidiaries (such subsidiaries, together with Horizon, collectively, the “Acquired Companies”) and the Transaction, and made its own assessment and is satisfied concerning the relevant financial, tax and other economic considerations relevant to Subscriber’s investment in the Subscribed Shares.

Subscriber further acknowledges that the proxy statement/prospectus that Holdco intends to file with the Commission will include substantial additional information about Holdco, the SPAC, the Acquired Companies, and the Transaction and will update and supersede the information previously provided to Subscriber. Subscriber represents and agrees that Subscriber and Subscriber’s professional advisor(s), if any, have had the opportunity to ask such questions, receive such answers and obtain such information as Subscriber and Subscriber’s professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the Subscribed Shares. Subscriber acknowledges and agrees that none of the SPAC, Holdco, the Acquired Companies or the Placement Agent, or any of their respective affiliates, or any of such person’s or its affiliate’s control persons, officers, directors, employees or other representatives, legal counsel, financial advisors, accountants or agents (collectively, “Representatives”) has provided Subscriber with any advice with respect to the Subscribed Shares nor is such advice necessary or desired. None of the SPAC, Holdco, the Acquired Companies, the Placement Agent or any of their respective affiliates or Representatives has made or makes any representation as to the SPAC, Holdco, or the Acquired Companies or the quality or value of the Subscribed Shares or the Transaction, except as expressly set forth in this Subscription Agreement. In addition, the Placement Agent and any of its affiliates or Representatives may have acquired non-public information with respect to the SPAC, Holdco, or the Acquired Companies which Subscriber agrees need not be provided to it. In connection with the issuance of the Subscribed Shares to Subscriber, none of the Placement Agent or any of its affiliates has acted as a financial advisor or fiduciary to Subscriber.

Neither the SPAC, Holdco, Horizon nor any of their affiliates has offered Subscriber any tax advice relating to Subscriber’s investment in the Subscribed Shares, or made any representations, warranties or guarantees regarding the tax consequences of Subscriber’s investment in the Subscribed Shares. Subscriber 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. Subscriber understands and acknowledges that the subscription for and allotment and issuance of the Subscribed Shares hereunder meets (i) the exemptions from filing under FINRA Rule 5123(b)(1)(A) and (ii) the institutional customer exemption under FINRA Rule 2111(b).

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

Part 800.224) in which the national or subnational governments of a single foreign state have a substantial interest (as defined in 31 C.F.R. Part 800.244) will acquire a substantial interest in Holdco as a result of the subscription for and allotment and issuance of Subscribed Shares hereunder such that a declaration to the Committee on Foreign Investment in the United States would be mandatory under 31 C.F.R. Part 800.401, and no foreign person will have control (as defined in 31 C.F.R.

“THIS SECURITY WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND THIS SECURITY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM.

(v) Subscriber acknowledges and is aware that the Placement Agent is acting as financial advisor to the SPAC in connection with the Transaction.

Section 7 Registration Rights.

(a) Holdco shall, within fifteen (15) Business Days after the Closing (the “Filing Deadline”), file with the Commission (at Holdco’s sole cost and expense) a registration statement registering the resale of the Subscribed Shares (the “Registration Statement”), and 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) the 60th calendar day (or 90th calendar day if the Commission notifies Holdco that it will “review” the Registration Statement) following the earlier of (A) the filing of the Registration Statement and (B) Filing Deadline and (ii) the 5th calendar day after Holdco is notified (orally or in writing, whichever is earlier) by the Commission that the Registration Statement will not be “reviewed” or will not be subject to further review (such earlier date, the “Effectiveness Deadline”); provided, that (i) if the filing or effectiveness of the Registration Statement would require financial statements which have not been filed by Holdco with the Commission (other than as a result of Holdco’s failure to timely file its financial statements), then the Filing Deadline and/or the Effectiveness Deadline, as

19

applicable, shall automatically be extended to the second Business Day following the date that Holdco files the applicable report containing the required financial statements, (ii) if the Effectiveness Deadline falls on a Saturday, Sunday or other day that the Commission is closed for business, the Effectiveness Deadline shall be extended to the next Business Day on which the Commission is open for business and (iii) if the Commission is closed for business due to a government shutdown, the Effectiveness Deadline shall be extended by the same number of Business Days on which the Commission remains closed. Holdco shall provide a draft of the Registration Statement to the Subscriber for review at least two Business Days in advance of filing the Registration Statement. Notwithstanding the foregoing, if the Commission prevents Holdco 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 by the applicable stockholders or otherwise, such Registration Statement shall register for resale such number of Class A Ordinary Shares which is equal to the maximum number of shares as is permitted by the Commission. In such event, the number of Subscribed Shares and any other shares to be registered for each selling stockholder named in the Registration Statement shall be reduced pro rata among all such selling stockholders and as promptly as practicable after being permitted to register additional shares under Rule 415 under the Securities Act, Holdco shall file one or more new Registration Statement(s) (such new Registration Statement shall also be deemed to be “Registration Statement” hereunder) to register such additional Subscribed Shares and cause such Registration Statement(s) to become effective as promptly as practicable after the filing thereof consistent with the terms of this Section 7. Any failure by Holdco to file a Registration Statement by the Filing Deadline or to effect the Registration Statement by the Effectiveness Deadline shall not otherwise relieve Holdco of its obligations to file or effect a Registration Statement as set forth in this Section 7.

(b) Holdco’s obligation to include the Subscribed Shares in the Registration Statement is contingent upon Subscriber furnishing in writing to Holdco such information regarding Subscriber, the securities of Holdco held by Subscriber and the intended method of disposition of the Subscribed Shares (which shall be limited to non-underwritten public offerings) as shall be reasonably requested by Holdco to effect the registration of the Subscribed Shares, and shall execute such documents in connection with such registration as Holdco may reasonably request that are customary of a selling stockholder in similar situations. Unless required under applicable laws and Commission rules, in no event shall the Subscriber be identified as a statutory underwriter in the Registration Statement; provided, that if the Subscriber is required to be so identified as a statutory underwriter in the Registration Statement, the Subscriber will have an opportunity to withdraw its Subscribed Shares from the Registration Statement. Holdco agrees that, except for such times as Holdco is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, Holdco will use its commercially reasonable efforts to, at its expense, cause such Registration Statement to remain effective with respect to Subscriber, keep any qualification, exemption or compliance under state securities laws which Holdco determines to obtain continuously effective with respect to Subscriber, and to keep the applicable Registration Statement or any subsequent shelf registration statement free of any material misstatements or omissions, until the earliest of (i) three years from the issuance of the Subscribed Shares, (ii) the date on which all of the Subscribed Shares shall have been sold, or (iii) on the first date on which Subscriber can sell all of its Subscribed Shares (or shares received in exchange therefor) under Rule 144 of the Securities Act without limitation as to the manner of sale, the amount of such securities that may be sold and without the requirement for Holdco to be in compliance with the

20

current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable). For as long as the Registration Statement shall remain effective pursuant to the immediately preceding sentence, Holdco shall use commercially reasonable efforts qualify the Subscribed Shares for listing on the applicable Stock Exchange on which the Class A Ordinary Shares are then listed, and update or amend the Registration Statement as necessary to include the Subscribed Shares. Holdco shall be entitled to delay or postpone the effectiveness of the Registration Statement, and from time to time to require Subscriber not to sell under the Registration Statement or to suspend the effectiveness thereof, if, in the good faith judgment of the Chief Executive Officer, the President, such other principal executive officer, the Chief Financial Officer, or the principal financial officer of Holdco, after consultation with outside counsel to Holdco, (1) the filing, effectiveness, or continued use of a Registration Statement pursuant to the terms of this Subscription Agreement would be seriously detrimental to Holdco, (2) the filing, effectiveness, or continued use of a Registration Statement would require public disclosure of material non-public information or financial statements which would not be required to be made at such time but for the filing, effectiveness, or continued use of such Registration Statement or prospectus, as the case may be, and Holdco has (x) a bona fide business purpose for not making such information public or (y) determined the premature disclosure of such information would materially adversely affect Holdco, or (3) the Registration Statement or prospectus contains an untrue statement of a material fact or an omission to state a material fact required to be stated therein, or necessary to make the statements therein (in the case of any prospectus, in the light of the circumstances under which they were made) not misleading, or in the opinion of counsel for Holdco it is necessary to supplement or amend such Registration Statement or prospectus to comply with law (such circumstance, a “Suspension Event”); provided, however, that Holdco may not delay or suspend the Registration Statement on more than three occasions or for more than sixty (60) consecutive calendar days, or more than ninety (90) total calendar days, in each case during any twelve-month period and Holdco shall use commercially reasonable efforts to make such Registration Statement available for the sale by Subscriber of such securities as soon as practicable thereafter. Upon receipt of any written notice from Holdco (which notice shall not contain any material non-public information regarding Holdco) of the happening of any Suspension Event during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the prospectus) not misleading, which notice shall be given no later than three (3) Business Days from the date the determination that a Suspension Event has occurred, Subscriber agrees that (i) it will immediately discontinue offers and sales of the Subscribed Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until Subscriber receives copies of a supplemental or amended prospectus (which the Holdco agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by Holdco that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by Holdco except (A) for disclosure to Subscriber’s employees, agents and professional advisers who need to know such information and are obligated to keep it confidential, (B) for disclosures to the extent required in order to comply with reporting obligations to its limited partners who have agreed to keep such information confidential and (C) as otherwise required by law or subpoena. If so directed by Holdco, Subscriber will, in Subscriber’s sole discretion, deliver to Holdco or destroy, all copies of the prospectus covering the Subscribed Shares in Subscriber’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Subscribed Shares shall not apply (i) to the extent Subscriber is required to retain a copy of such prospectus (a) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (b) in accordance with a bona fide pre-existing document retention policy or (ii) to copies stored electronically on archival servers as a result of automatic data back-up.

(c) The Subscriber may deliver written notice (an “Opt-Out Notice”) to Holdco requesting that the Subscriber not receive notices from Holdco otherwise required by Section 7(b); provided, however, that the Subscriber may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from the Subscriber (unless subsequently revoked), (i) Holdco shall not deliver any such notices to the Subscriber and the Subscriber shall no longer be entitled to the rights associated with any such notice and (ii) each time prior to the Subscriber’s intended use of an effective Registration Statement, the Subscriber will notify Holdco in writing at least two (2) Business Days in advance of such intended use, and if a notice of a Suspension Event was previously delivered (or would have been delivered but for the provisions of this Section 7(c)) and the related suspension period remains in effect, Holdco will so notify the Subscriber within one (1) Business Day of the Subscriber’s notification to Holdco by delivering to the Subscriber a copy of such previous notice of Suspension Event, and thereafter will provide the Subscriber with the related notice of the conclusion of such Suspension Event promptly following its availability.

(d) In the case of the registration effected by Holdco pursuant to this Subscription Agreement, Holdco shall notify the Subscriber by email as promptly as practicable:

(i) when a Registration Statement or any amendment thereto has been filed with the Commission and when such Registration Statement or any post-effective amendment thereto has become effective;

(ii) of the issuance by the Commission 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 Holdco of any notification with respect to the suspension of the qualification of the Subscribed Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose;

(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; and

(v) of any request by the Commission for any amendment or supplement to the Registration Statement or any prospectus or for additional information, and shall provide the Subscriber with copies thereof.

22

Notwithstanding anything to the contrary set forth herein, Holdco shall not, when so advising Subscriber of such events, provide Subscriber with any material, nonpublic information regarding Holdco other than to the extent that providing notice to Subscriber of the occurrence of the events listed in (i) through (v) above may constitute material, nonpublic information regarding Holdco.

(e) Holdco 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.

(f) Except for such times as Holdco is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement as contemplated by this Subscription Agreement, Holdco 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 subscribers for the Subscribed 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.

(g) Holdco shall use its commercially reasonable efforts to cause all Subscribed Shares to be listed on each securities exchange or market, if any, on which the Class A Ordinary Shares have been listed.

(h) Holdco shall use its commercially reasonable efforts to take all other steps necessary to effect the registration of the Subscribed Shares required hereby.

(i) For purposes of this Section 7, “Subscribed Shares” shall mean, as of any date of determination, the Subscribed Shares and any other equity security issued or issuable with respect to the Subscribed Shares by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event, and “Subscriber” shall include any affiliate of the Subscriber to which the rights under this Section 7 shall have been duly assigned.

(j) Notwithstanding anything to the contrary, if at any time following the filing of a Registration Statement, Holdco or SPAC determines that is eligible to register the Registrable Securities on Form S-3 or Form F-3, then Holdco and SPAC shall use its reasonable best efforts to (i) as promptly as possible after such determination amend the Registration Statement or file a new Registration Statement on Form S-3 or Form F-3; (ii) have such Registration Statement declared effective by the Commission, if applicable; and (iii) keep such Registration Statement effective during the period during which such Registration Statement is required to be kept effective in accordance with this Subscription Agreement.

23

Section 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 earliest to occur of (a) such date and time as the Transaction Agreement is terminated in accordance with its terms; (b) upon the mutual written agreement of the parties hereto to terminate this Subscription Agreement; (c) if, on the Closing Date, any of the conditions to the Closing set forth in Section 2 are not satisfied or waived and, as a result thereof, the transactions contemplated by this Subscription Agreement are not consummated at the Closing; and (d) the Outside Date (as such term is defined in the Transaction Agreement), if the closing of the transactions contemplated by the Transaction Agreement shall not have occurred prior to such date; provided, that the Outside Date may not be extended to any date that is more than 18 months following the date hereof without the Subscriber’s prior written consent; provided, further, that nothing herein will relieve any party from liability for any willful breach hereto 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 such breach. Holdco shall notify Subscriber of the termination of the Transaction Agreement promptly after the termination thereof. Upon the termination of this Subscription Agreement in accordance with this Section 8, any monies paid by the Subscriber to Holdco in connection herewith shall be promptly (and in any event within one Business Day after such termination) returned to the Subscriber, without any deduction for or on account of any tax withholding except as required by law, charges or set-off.

Section 9 Trust Account Waiver. Subscriber hereby acknowledges that the SPAC has established a trust account (the “Trust Account”) containing the proceeds of its initial public offering (the “IPO”) and from certain private placements occurring simultaneously with the IPO (including interest accrued from time to time thereon) for the benefit of the SPAC’s public stockholders and certain other parties (including the underwriters of the IPO). For and in consideration of the SPAC entering into this Subscription Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Subscriber hereby (a) agrees that it does not now and shall not at any time hereafter have any right, title, interest or claim of any kind in or to any assets held in the Trust Account, and shall not make any claim against the Trust Account, regardless of whether such claim arises as a result of, in connection with or relating in any way to this Subscription Agreement or any other matter, and regardless of whether such claim arises based on contract, tort, equity or any other theory of legal liability (any and all such claims are collectively referred to hereafter as the “Released Claims”), (b) irrevocably waives any Released Claims that it may have against the Trust Account now or in the future as a result of, or arising out of, any negotiations, contracts or agreements with the SPAC, and (c) will not seek recourse against the Trust Account for any reason whatsoever; provided, however, that nothing in this Section 9 shall (x) be deemed to limit any of Subscriber’s right, title, interest or claim to the Trust Account by virtue of such Subscriber’s record or beneficial ownership of securities of the SPAC acquired by any means other than pursuant to this Subscription Agreement, including but not limited to any redemption right with respect to any such securities of the SPAC, (y) serve to limit or prohibit Subscriber’s right to pursue a claim against the SPAC for legal relief against assets held outside the Trust Account, for specific performance or other equitable relief or (z) serve to limit or prohibit any claims that Subscriber may have in the future against the SPAC’s assets or funds that are not held in the Trust Account.

24

Section 10 Indemnity.

(a) Holdco agrees to indemnify and hold harmless, to the extent permitted by law, the Subscriber (to the extent Subscriber is a seller under the Registration Statement), its directors, officers, employees, advisers, and agents, each person who controls the Subscriber (within the meaning of the Securities Act or the Exchange Act) and each affiliate of the Subscriber (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 and documented attorneys’ fees and expenses incurred in connection with defending or investigating any such action or claim) (collectively, “Losses”) resulting from, based upon or arising out of any untrue or alleged untrue statement of material fact contained in the Registration Statement, prospectus included in the Registration Statement or preliminary prospectus or any amendment thereof or supplement thereto, or document incorporated therein by reference, or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances in which they were made) not misleading, except to the extent, but only to the extent, that such untrue statements, alleged untrue statements, omissions or alleged omissions are based upon information regarding the Subscriber furnished in writing to Holdco by or on behalf of the Subscriber expressly for use therein.

(b) To the extent the Subscriber is identified as a selling stockholder in the Registration Statement or any other registration statement which covers the Subscribed Shares, the Subscriber agrees, severally and not jointly with any Other Subscriber or other selling stockholder named in the Registration Statement, to indemnify and hold harmless Holdco, its directors, officers, employees, advisers and agents, each person who controls Holdco (within the meaning of the Securities Act or the Exchange Act), and each affiliate of Holdco against any Losses resulting from, based upon or arising out of any untrue or alleged untrue statement of material fact contained in the Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances in which they were made) not misleading, to the extent but only to the extent that such untrue statements, alleged untrue statements, omissions or alleged omissions are based upon information regarding the Subscriber furnished in writing to Holdco by or on behalf of the Subscriber expressly for use therein. In no event shall the liability of the Subscriber be greater in amount than the dollar amount of the net proceeds received by the Subscriber upon the sale of the Subscribed Shares subscribed for pursuant to this Subscription Agreement giving rise to such indemnification obligation. Notwithstanding the foregoing, Subscriber’s indemnification obligations shall not apply to amounts paid in settlement of any Losses if such settlement is effected without the prior written consent of Subscriber (which consent shall not be unreasonably withheld, delayed or conditioned).

(c) 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 (but such consent shall not be unreasonably withheld, conditioned or delayed). 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.

25

(d) 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 Subscribed Shares subscribed for pursuant to this Subscription Agreement.

(e) If the indemnification provided under this Section 10 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any Losses 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 in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by (or not made by, in the case of an omission), or relates to information supplied by or on behalf of, 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 in this Section 10, 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 10 from any person who was not guilty of such fraudulent misrepresentation. Any contribution pursuant to this Section 10(e) by any seller of Subscribed Shares, together with any amounts under Section 10(b), shall be limited in amount to the amount of net proceeds received by such seller from the sale of such Subscribed Shares pursuant to the Registration Statement. Notwithstanding anything to the contrary herein, in no event will any party be liable for consequential, special, exemplary or punitive damages in connection with this Subscription Agreement.

Section 11 Holdco’s Covenants.

(a) In connection with any sale or other disposition of the Subscribed Shares pursuant to an effective Registration Statement with a current prospectus or Rule 144 promulgated under the Securities Act (or any successor rule promulgated thereafter by the Commission) or pursuant to any other exemption under the Securities Act such that the Subscribed Shares held by the Subscriber become freely tradable without any current public information or other conditions and upon compliance by the Subscriber with the requirements of this Section 11(a), if requested by the Subscriber, Holdco shall use commercially reasonable efforts to (i) cause Holdco’s transfer agent (the “Transfer Agent”) to remove any restrictive legends from the Subscribed Shares and cause the Transfer Agent to issue new, unlegended entries for such book entry Subscribed Shares sold

26

or disposed of without restrictive legends within one (1) trading day upon any such request therefor from the Subscriber; provided that Holdco and the Transfer Agent shall have received such customary representations and other documentation reasonably acceptable to Holdco and the Transfer Agent in connection therewith including, but not limited to, customary representations that such Subscribed Shares (x) have been sold or transferred pursuant to an effective registration statement (including the Registration Statement) with a current prospectus, pursuant to the plan of distribution set forth in such prospectus or (y) have been sold pursuant to Rule 144. Subject to receipt from Subscriber by Holdco and the Transfer Agent of customary representations and other documentation reasonably acceptable in connection therewith, Subscriber may request that Holdco remove any legend from the book-entry position evidencing its Subscribed Shares following the earliest of such time as such Subscribed Shares (i) have been sold or transferred pursuant to an effective registration statement (including the Registration Statement) or (ii) have been sold pursuant to Rule 144. If restrictive legends are no longer required for such Subscribed Shares pursuant to the foregoing, Holdco shall, in accordance with the provisions of this section and as soon as reasonably practicable and in any case within one (1) trading day of any request therefor from Subscriber 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 instructions that the Transfer Agent shall make a new, unlegended entry for such book entry Subscribed Shares. To the extent required by the Transfer Agent, Holdco shall use commercially reasonable efforts to cause its legal counsel to deliver a customary opinion as soon as reasonably practicable and in any case within one (1) trading day of the delivery of all reasonably necessary representations and other documentation from the Subscriber as reasonably requested by the Transfer Agent. Holdco shall be responsible for the fees of its Transfer Agent, its legal counsel and all DTC fees associated with such issuance.

(b) With a view to making available to Subscriber the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or regulation of the Commission that may at any time permit Subscriber to sell securities of Holdco to the public without registration, Holdco agrees, from the one-year anniversary of the filing of “Form 10” information with the Commission following the Closing Date until the Subscribed Shares are sold by Subscriber, to (i) make and keep public information available, as those terms are understood and defined in Rule 144; (ii) file with the Commission in a timely manner all reports and other documents required of Holdco under the Exchange Act so long as Holdco remains subject to such requirements and the filing of such reports and other documents is required for the applicable provisions of Rule 144; and (iii) furnish to Subscriber so long as it owns the Subscribed Shares, as promptly as reasonably practicable upon request, (A) a written statement by Holdco, if true, that it has complied with the reporting requirements of Rule 144, (B) a copy of the most recent annual report of Holdco and such other reports and documents so filed by Holdco with the Commission and (C) such other information as may be reasonably requested to permit Subscriber to sell such securities pursuant to Rule 144 without registration.

Section 12 Miscellaneous.

(a) All notices, requests, demands, claims, and other communications hereunder shall be in writing. Any notice, request, demand, claim, or other communication hereunder shall be deemed to have been duly given (i) when delivered in person, (ii) when delivered by internationally recognized overnight delivery service, or (iii) when delivered by email (in each case in this clause (iii) solely if receipt is confirmed, but excluding any automated reply, such as an out-of-office notification), in each case, addressed to the intended recipient at its address specified on the signature page hereof or to such electronic mail address or address as subsequently modified by written notice given in accordance with this Section 12(a).

27

(b) Subscriber acknowledges that the SPAC, Holdco, Horizon and the Placement Agent will rely on the acknowledgments, understandings, agreements, representations and warranties of Subscriber contained in this Subscription Agreement; provided, however, that the foregoing clause of this Section 12(b) shall not give the Placement Agent any rights other than those expressly set forth herein. Prior to the Closing, Subscriber agrees to promptly notify the SPAC, Holdco, Horizon and the Placement Agent if it becomes aware that any of the acknowledgments, understandings, agreements, representations and warranties of Subscriber set forth herein are no longer accurate in all material respects. Holdco acknowledges that Subscriber will rely on the acknowledgments, understandings, agreements, representations and warranties of Holdco contained in this Subscription Agreement. Prior to the Closing, Holdco agrees to promptly notify Subscriber and the Placement Agent if it becomes aware that any of the acknowledgments, understandings, agreements, representations and warranties of Holdco set forth herein are no longer accurate in all material respects.

(c) Each of the SPAC, Horizon, Holdco, the Placement Agent and Subscriber is 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.

(d) Except as otherwise provided herein, each party shall pay all of its own expenses in connection with this Subscription Agreement and the transactions contemplated herein.

(e) The Subscriber hereby acknowledges and agrees that it will not, nor will any person acting at the Subscriber’s direction or pursuant to any understanding with the Subscriber, directly or indirectly offer, sell, pledge, contract to sell, sell any option, engage in hedging activities or execute any “short sales” as defined in Rule 200 of Regulation SHO under the Exchange Act, of the Subscribed Shares until the consummation of the Transaction (or such earlier termination of this Subscription Agreement in accordance with its terms). This Section 12(e) shall not apply to any sale (including the exercise of any redemption right) of securities of the SPAC (i) held by the Subscriber, its controlled affiliates or any person or entity acting on behalf of Subscriber or any of its controlled affiliates prior to the execution of this Subscription Agreement or (ii) acquired by by Subscriber, its controlled affiliates or any person or entity acting on behalf of Subscriber or any of its controlled affiliates in open market transactions after the execution of this Subscription Agreement in each case, provided that such action does not create any “put equivalent position,” as such term is defined in Rule 16a-1 under the Exchange Act, or short positions, with respect to the Subscribed Shares. In addition, notwithstanding the foregoing, (1) nothing herein shall prohibit other entities under common management with the Subscriber (including the Subscriber’s controlled affiliates and/or affiliates) from entering into any “short sales”, (2) in the case of a Subscriber that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Subscriber’s assets, the restrictions set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to subscribe for the Subscribed Shares covered by this Subscription Agreement, and (3) nothing herein shall prohibit Subscriber from pledging the Subscribed Shares in connection with a bona fide margin agreement, provided such pledge shall be (x) pursuant to an available exemption from the registration requirements of the Securities Act or (y) pursuant to, and in accordance with, a registration statement that is effective under the Securities Act at the time of such pledge, and provided, further, that neither Holdco nor its counsel shall be required to take any action (or refrain from taking any action) in connection with any such pledge, other than providing any such lender of such margin agreement with an acknowledgment that the Subscribed Shares are not subject to any contractual prohibition on pledging or lock up, the form of such acknowledgment to be subject to review and comment by Holdco in all respects.

28

(f) Neither this Subscription Agreement nor any rights that may accrue to Subscriber hereunder (other than the Subscribed Shares acquired hereunder, if any) may be transferred or assigned. Neither this Subscription Agreement nor any rights that may accrue to Holdco, the SPAC or Horizon hereunder may be transferred or assigned (provided, that, for the avoidance of doubt, Holdco may transfer the Subscription Agreement and its rights hereunder solely in connection with the consummation of the Transaction and exclusively to another entity under the control of, or under common control with, Holdco). Notwithstanding the foregoing, Subscriber may assign its rights and obligations under this Subscription Agreement to one or more of its affiliates or to other investment funds or accounts managed or advised by the investment manager who acts on behalf of Subscriber or, with the prior written consent of Holdco, the SPAC, and Horizon, to another person, provided that no such assignment shall relieve Subscriber of its obligations hereunder if any such assignee fails to perform such obligations.

(g) All 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.

(h) Holdco and the SPAC may request from Subscriber such additional information as Holdco or the SPAC may reasonably deem necessary to evaluate the eligibility of Subscriber to acquire the Subscribed Shares and to register the Subscribed Shares for resale, and Subscriber shall provide such information as may be reasonably requested, to the extent within Subscriber’s possession and control or otherwise readily available to Subscriber; provided that each of Holdco and the SPAC agrees to keep any such information confidential except to the extent such information is already publicly available, such information is or becomes available to Holdco or the SPAC on a non-confidential basis from a source other than Subscriber, or to the extent required to be disclosed by applicable law or reasonably necessary to register the Subscribed Shares for resale. Subscriber acknowledges that Holdco and the SPAC may file a copy of the form of this Subscription Agreement with the Commission as an exhibit to a periodic report of the SPAC or a registration statement of Holdco or the SPAC.

(i) This Subscription Agreement may not be amended, modified or waived except by an instrument in writing, signed by each of the parties hereto; provided, that no provision of this Subscription Agreement that references the Placement Agent may be amended, modified, terminated or waived in any manner that is adverse to the Placement Agent without the written consent of the Placement Agent.

29

(j) This Subscription Agreement 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.

(k) 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 is not for the benefit of, nor may any provision hereof be enforced by, any other person. The parties hereto acknowledge and agree that the Placement Agent is a third-party beneficiary of the acknowledgements, representations, warranties and covenants of (i) Holdco contained in Section 3, (ii) SPAC contained in Section 4, (iii) Horizon contained in Section 5, (iv) Subscriber contained in Section 6, Section 12(b), Section 12(e) and this Section 12(k).

(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 and that money or other legal remedies would not be an adequate remedy for such damage. It is accordingly agreed that the parties shall be entitled to equitable relief, including in the form of an injunction or injunctions to prevent breaches or threatened breaches of this Subscription Agreement and 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 each of Holdco and the SPAC shall be entitled to specifically enforce Subscriber’s obligations to fund the Subscription Price and the provisions of the Subscription Agreement, in each case, on the terms and subject to the conditions set forth herein. The parties hereto further acknowledge and agree: (x) to waive any requirement for the security or posting of any bond in connection with any such equitable remedy; (y) not to assert that a remedy of specific enforcement pursuant to this Section 12(l) is unenforceable, invalid, contrary to applicable law or inequitable for any reason; and (z) to waive any defenses in any action for specific performance, including the defense that a remedy at law would be adequate.

(m) In any dispute arising out of or related to this Subscription Agreement, or any other agreement, document, instrument or certificate contemplated hereby, or any transactions contemplated hereby or thereby, the applicable adjudicating body shall award to the prevailing party, if any, the costs and attorneys’ fees reasonably incurred by the prevailing party in connection with the dispute and the enforcement of its rights under this Subscription Agreement or any other agreement, document, instrument or certificate contemplated hereby and, if the adjudicating body determines a party to be the prevailing party under circumstances where the prevailing party won on some but not all of the claims and counterclaims, the adjudicating body may award the prevailing party an appropriate percentage of the costs and attorneys’ fees reasonably incurred by the prevailing party in connection with the adjudication and the enforcement of its rights under this Subscription Agreement or any other agreement, document, instrument or certificate contemplated hereby or thereby.

(n) If any provision of this Subscription Agreement shall 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.

30

(o) No failure or delay by a party hereto in exercising any right, power or remedy under this Subscription Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise of any right, power or remedy under this Subscription Agreement by a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Subscription Agreement shall entitle the party receiving such notice or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any circumstances without such notice or demand.

(p) This Subscription Agreement may be executed and delivered 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.

(q) This Subscription Agreement, and any claim or cause of action hereunder based upon, arising out of or related to this Subscription Agreement (whether based on law, in equity, in contract, in tort or any other theory) or the negotiation, execution, performance or enforcement of this Subscription Agreement, shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to the principles of conflicts of laws that would otherwise require the application of the law of any other state.

(r) EACH PARTY AND ANY PERSON ASSERTING RIGHTS AS A THIRD PARTY BENEFICIARY HEREBY WAIVES ITS RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OR RELATED TO THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY IN ANY ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY OR ANY AFFILIATE OF ANY OTHER SUCH PARTY, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS OR OTHERWISE. THE PARTIES AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS SUBSCRIPTION AGREEMENT OR ANY PROVISION HEREOF. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS SUBSCRIPTION AGREEMENT.

31

(s) The parties agree that all disputes, legal actions, suits and proceedings arising out of or relating to this Subscription Agreement must be brought exclusively in the New York Supreme Court, Commercial Division, located in the Borough of Manhattan in the City of New York, in the State of New York or if such court declines jurisdiction, then to any court of the State of New York or the Federal District Court for the Southern District of New York (collectively the “Designated Courts”). Each party hereby consents and submits to the exclusive jurisdiction of the Designated Courts. No legal action, suit or proceeding with respect to this Subscription Agreement may be brought in any other forum. Each party hereby irrevocably waives all claims of immunity from jurisdiction, and any objection which such party may now or hereafter have to the laying of venue of any suit, action or proceeding in any Designated Court, including any right to object on the basis that any dispute, action, suit or proceeding brought in the Designated Courts has been brought in an improper or inconvenient forum or venue. Each of the parties also agrees that delivery of any process, summons, notice or document to a party hereof in compliance with Section 12(a) of this Subscription Agreement shall be effective service of process for any action, suit or proceeding in a Designated Court with respect to any matters to which the parties have submitted to jurisdiction as set forth above.

(t) This Subscription Agreement may only be enforced against, and any claim, action, suit or other legal proceeding based upon, arising out of, or related to this Subscription Agreement, or the negotiation, execution or performance of this Subscription Agreement, may only be brought against the entities that are expressly named as parties hereto and then only with respect to the specific obligations set forth herein with respect to such party or third party beneficiary. No past, present or future director, officer, employee, incorporator, manager, member, partner, stockholder, affiliate, agent, attorney or other representative of any party hereto or of any affiliate of any party hereto, or any of their successors or permitted assigns, shall have any liability for any obligations or liabilities of any party hereto under this Subscription Agreement or for any claim, action, suit or other legal proceeding based on, in respect of or by reason of the transactions contemplated hereby.

(u) If any change in the Class A Ordinary Shares shall occur between the date hereof and immediately prior to the Closing by reason of any reclassification, recapitalization, share split or consolidation, exchange or readjustment of shares, or any stock dividend, the number of Subscribed Shares issued to Subscriber shall be appropriately adjusted to reflect such change.

(v) None of Holdco, the SPAC and Horizon shall, without the prior written consent (including by e-mail) of Subscriber, use or disclose the name of Subscriber or any of its advisors or affiliates or any information relating to the Subscriber or this Subscription Agreement, other than to Holdco’s lawyers, independent accountants and to other advisors and service providers who reasonably require such information in connection with the provision of services to such person, are advised of the confidential nature of such information and are obligated to keep such information confidential. Without the Subscriber’s prior written consent, none of Holdco, the SPAC and Horizon shall (i) use the name of Subscriber or any of its advisors or affiliates in any press release, marketing or similar materials or (ii) publicly disclose the name of Subscriber or any of its advisors or affiliates, or include the name of Subscriber or any of its advisors or affiliates in any filing with the Commission or any regulatory agency or trading market, in any other documents or communications provided by the SPAC, Horizon or Holdco to any governmental entity or to any securityholders of Holdco, the SPAC or Horizon or in any other form of public disclosure, in each case, except to the extent required by the federal securities laws, Stock Exchange or OTC Markets rules, the Commission or any other securities authorities or any rules and regulations promulgated thereby, and if required, Holdco and the SPAC may disclose the Subscriber’s identity and beneficial ownership of the Subscribed Shares and the nature of Subscriber’s commitments, arrangements and understandings under and relating to this Subscription Agreement and, if

receive such notice or communication, and in the absence of any such indication, the Subscriber, the other holders of the Subscribed Shares and their respective affiliates, agents and representatives shall be allowed to presume that all matters relating to such notice or communication do not constitute MNPI. In addition, effective upon the issuance of such Disclosure Document, except as may otherwise be agreed with the Subscriber, without the Subscriber’s prior written consent (email being sufficient), each of Holdco and SPAC acknowledges and agrees that any and all confidentiality or similar obligations under any agreement, whether written or oral, between Holdco and SPAC any of their respective subsidiaries or any of their officers, directors, agents, employees or affiliates on the one hand, and the Subscriber or any of its affiliates on the other hand, shall terminate and be of no further force or effect.]³ Each of Holdco and the SPAC understands and confirms that the Subscriber shall be relying on the foregoing covenant in effecting transactions in securities of Holdco. If Holdco or SPAC does provide material, non-public information or confidential or proprietary information to the Subscriber without the Subscriber’s written consent, Holdco shall promptly file such information with the Commission pursuant to a Current Report on Form 8-K and the Subscriber shall not be subject to any duty of confidentiality contained herein with respect to such information. The obligations of Subscriber under this Subscription Agreement are several and not joint with the obligations of any Other Subscriber under the Other Subscription Agreements, and Subscriber shall not be responsible in any way for the performance of the obligations of any Other Subscriber under the Other Subscription Agreements. The decision of Subscriber to subscribe for Subscribed Shares pursuant to this Subscription Agreement has been made by Subscriber independently of any Other Subscriber and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the SPAC, Horizon, Holdco or any of their respective subsidiaries which may have been made or given by any Other Subscriber or investor or by any agent or employee of any Other Subscriber or investor, and neither Subscriber nor any of its agents or employees shall have any liability to any Other Subscriber or 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 Subscriber or investor pursuant hereto or thereto, shall be deemed to constitute Subscriber and Other Subscribers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that Subscriber and Other Subscribers are in any way acting in concert or as a group (within the meaning of Section 13(d) of the Exchange Act) with respect to such obligations or the transactions contemplated by this Subscription Agreement and the Other Subscription Agreements. Subscriber acknowledges that no Other Subscriber has acted as agent for Subscriber in connection with making its investment hereunder and no Other Subscriber will be acting as agent of Subscriber in connection with monitoring its investment in the Subscribed Shares or enforcing its rights under this Subscription Agreement.
