Section 5. Registration Matters.

(a) Pubco agrees to use commercially reasonable efforts to cause the Pubco Class A Common Stock into which the Subscribed Company Exchange Units held by Subscribers will be eligible to be converted following consummation of the Company Merger (such securities, the “Registrable Securities”) to be registered on the Form S-4.

19

(b) To the extent that any Registrable Securities are unable to be included on the Form S-4, then, subject to Section (c), Pubco agrees that, as soon as practicable but in no event later than thirty (30) calendar days following the consummation of the Transactions Pubco will file with the Commission (at Pubco’s sole cost and expense) a registration statement registering the resale of such Registrable Securities (such registration statement, the “Registration Statement”), and Pubco shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, but in any event no later than ninety (90) calendar days after the closing of the Transactions (the “Effectiveness Deadline”); provided, that the Effectiveness Deadline shall be extended by a maximum of ninety (90) calendar days after the closing of the Transactions if the Registration Statement is reviewed by, and comments thereto are provided from, the Commission; provided, further, that Pubco shall request the Registration Statement declared effective promptly after the date Pubco is notified (orally or in writing, whichever is earlier) by the staff of the Commission that the Registration Statement will not be “reviewed” or will not be subject to further review; provided, further, that (i) 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 (ii) if the Commission is closed for operations due to a government shutdown, the Effectiveness Deadline shall be extended by the same number of calendar days as the number of calendar days during which the Commission remains closed. Pubco will provide a draft of the Registration Statement to Subscriber at least two (2) business days in advance of the date of filing the Registration Statement with the Commission. Unless otherwise agreed to in writing by Subscriber prior to the filing of the Registration Statement, Subscriber shall not be identified as a statutory underwriter in the Registration Statement unless the Commission requests that Subscriber be identified as a statutory underwriter; provided, that if the Commission requests that Subscriber be identified as a statutory underwriter in the Registration Statement, Subscriber will have the opportunity to withdraw from the Registration Statement upon its prompt written request to Pubco. Notwithstanding the foregoing, if the Commission or its regulations prevent Pubco from including any or all of the Registrable Securities 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 Registrable Securities by the applicable stockholders or otherwise, such Registration Statement shall register for resale such number of Registrable Securities which is equal to the maximum number of Registrable Securities as is permitted by the Commission. In such event, the number of Registrable Securities shall be reduced pro rata among all such selling stockholders and as promptly as practicable after being permitted to register additional Registrable Securities under Rule 415 under the Securities Act, Pubco shall amend the Registration Statement or file one or more new Registration Statement(s) (with such amendment or new Registration Statement also being deemed to be a “Registration Statement” hereunder) to register such additional Registrable Securities and use commercially reasonable efforts to cause such amendment or Registration Statement(s) to become effective as promptly as practicable after the filing thereof, but in any event no later than thirty (30) calendar days after the filing of such Registration Statement (the “Additional Effectiveness Deadline”); provided, that the Additional Effectiveness Deadline shall be extended to ninety (90) calendar days after the filing of such Registration Statement, including any new Registration Statement or amended Registration Statement, if such Registration Statement is reviewed by, and comments thereto are provided from, the Commission; provided, further, that Pubco shall request that such Registration Statement be declared effective promptly after the date Pubco is notified (orally or in writing, whichever is earlier) by the staff of the Commission that such Registration Statement will not be “reviewed” or will not be subject to further review; provided, further, that (i) if such day falls on a Saturday, Sunday or other day that the Commission is closed for business, the Additional Effectiveness Deadline shall be extended to the next business day on which the Commission is open for business and (ii) if the Commission is closed for operations due to a government shutdown, the Effectiveness Deadline shall be extended by the same number of calendar days as the number of calendar days during which the Commission remains closed. Any failure by Pubco to file a Registration Statement by the Effectiveness Deadline or Additional Effectiveness Deadline shall not otherwise relieve Pubco of its obligations to file or effect a Registration Statement as set forth in this Section 5.

20

(c) Pubco agrees that, except for such times as Pubco is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, Pubco will use its commercially reasonable efforts to cause such Registration Statement to remain effective with respect to Subscriber, including to prepare and file any post-effective amendment to such Registration Statement or a supplement to the related prospectus such that the prospectus will not include any untrue statement or a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, until the earliest to occur of (i) the date on which Subscriber ceases to hold any Registrable Securities issued pursuant to this Subscription Agreement and (ii) the first date on which Subscriber can sell all of its Registrable Securities issued pursuant to this Subscription Agreement (or shares received in exchange therefor) under Rule 144 of the Securities Act without limitation as to the manner of sale or the amount of such securities that may be sold and without the requirement for Pubco to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable) (the earliest of clauses (i) and (ii), the “End Date”). Prior to the End Date, Pubco (i) will use commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable; (ii) file all reports, and provide all customary and reasonable cooperation, necessary to enable Subscriber to resell Registrable Securities pursuant to the Registration Statement; and (iii) qualify the Registrable Securities for listing on the Stock Exchange and update or amend the Registration Statement as necessary to include Registrable Securities. Pubco will use its commercially reasonable efforts to (A) for so long as Subscriber holds Registrable Securities, make and keep public information available (as those terms are understood and defined in Rule 144) and file with the Commission in a timely manner all reports and other documents required of Pubco under the Exchange Act so long as Pubco remains subject to such requirements to enable Subscriber to resell the Registrable Securities pursuant to Rule 144, (B) at the reasonable request of Subscriber, deliver all the necessary documentation to cause Pubco’s transfer agent to remove all restrictive legends from any Registrable Securities being sold under the Registration Statement or pursuant to Rule 144 at the time of sale of the Registrable Securities, and (C) cause its legal counsel to deliver to the transfer agent the necessary legal opinions required by the transfer agent, if any, in connection with the instruction under clause (B) upon the receipt of Subscriber representation letters and such other customary supporting documentation as requested by (and in a form reasonably acceptable to) such counsel. Subscriber agrees to disclose its beneficial ownership, as determined in accordance with Rule 13d-3 of the Exchange Act, of Registrable Securities to Pubco (or its successor) as may be reasonably required to enable Pubco to make the determination described above.

21

(d) Pubco’s obligations to include the Registrable Securities in the Registration Statement are contingent upon Subscriber furnishing in writing to Pubco a completed selling stockholder questionnaire in customary form that contains such information regarding Subscriber, the securities of Pubco held by Subscriber and the intended method of disposition of the Registrable Securities as shall be reasonably requested by Pubco to effect the registration of the Registrable Securities, and Subscriber shall execute such documents in connection with such registration as Pubco may reasonably request that are customary of a selling stockholder in similar situations, including providing that Pubco shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement (i) during any customary blackout or similar period or as permitted hereunder and (ii) as may be necessary in connection with the preparation and filing of a post-effective amendment to the Registration Statement following the filing of Pubco’s Annual Report on Form 10-K for its first completed fiscal year following the effective date of the Registration Statement; provided that Pubco shall request such information from Subscriber, including the selling stockholder questionnaire, at least five (5) business days prior to the anticipated date of filing the Registration Statement with the Commission. In the case of the registration effected by Pubco pursuant to this Subscription Agreement, Pubco shall, upon reasonable request, inform Subscriber as to the status of such registration. Subscriber shall not be entitled to use the Registration Statement for an underwritten offering of Registrable Securities. Notwithstanding anything to the contrary contained herein, Pubco may from time to time require Subscriber not to sell under the Registration Statement or suspend the use or effectiveness of any such Registration Statement if (A) it determines in good faith that in order for the registration statement to not contain a material misstatement or omission, an amendment thereto would be needed, including as a result of any request by the Commission for any amendment or supplement to such Registration Statement or any prospectus relating thereto or for additional information, (B) such filing or use would materially affect a bona fide business or financing transaction of Pubco or would require premature disclosure of information that would materially adversely affect Pubco, (C) in the good faith judgment of the majority of the members of Pubco’s board of directors, such filing or effectiveness or use of such Registration Statement would be seriously detrimental to Pubco, (D) the majority of the members of Pubco’s board of directors determines to delay the filing or initial effectiveness of, or suspend use of, a Registration Statement and such delay or suspension arises out of, or is a result of, or is related to or is in connection with the SEC Guidance or future Commission guidance directed at special purpose acquisition companies or companies that have consummated a business combination with a special purpose acquisition company, or any related disclosure or related matters, (E) as may be necessary in connection with the preparation and filing of a post-effective amendment to the Registration Statement following the filing of Pubco’s Annual Report on Form 10-K for its first completed fiscal year following the effective date of the Registration Statement, or (F) Subscriber agrees that (1) it will immediately discontinue offers and sales of the Registrable Securities under the Registration Statement until Subscriber receives copies of a supplemental or amended prospectus (which Pubco agrees to use commercially reasonable efforts to promptly prepare) that corrects the misstatement(s) or omission(s) referred to in Section 5(d)(A) and receives notice that any post-effective amendment has become effective or unless otherwise notified by Pubco that it may resume such offers and sales and (2) it will maintain the confidentiality of any information included in such written notice delivered by Pubco unless otherwise required by law, subpoena or regulatory request or requirement (each such circumstance, a “Suspension Event”); provided that (w) Pubco shall not so delay filing or so suspend the use of the Registration Statement for a period of more than forty- five (45) consecutive days or more than ninety (90) total calendar days in any consecutive three hundred sixty (360) day period, or more than two (2) times in any consecutive three hundred sixty (360) day period and (x) Pubco shall use commercially reasonable efforts to make such registration statement available for the sale by Subscriber of such securities as soon as practicable thereafter.

22

(e) Upon receipt of any written notice from Pubco of the happening of (i) an issuance by the Commission of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose, which notice shall be given no later than three (3) business days from the date of such event, (ii) any Suspension Event during the period that the Registration Statement is effective, which notice shall be given no later than three (3) business days from the date of such Suspension Event, or (iii) 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, Subscriber agrees that (1) it will immediately discontinue offers and sales of the Registrable Securities under the Registration Statement until Subscriber receives copies of a supplemental or amended prospectus (which Pubco agrees to use commercially reasonable efforts 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 Pubco that it may resume such offers and sales and (2) it will maintain the confidentiality of any information included in such written notice delivered by Pubco unless otherwise required by law, subpoena or regulatory request or requirement. If so directed by Pubco, Subscriber will deliver to Pubco or, in Subscriber’s sole discretion destroy, all copies of the prospectus covering the Registrable Securities in Subscriber’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Registrable Securities shall not apply (w) 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 (x) to copies stored electronically on archival servers as a result of automatic data back-up.

(f) For purposes of this Section 5, (i) “Registrable Securities” shall mean, as of any date of determination, the Registrable Securities and any other equity security issued or issuable with respect to the Registrable Securities by way of share split, dividend, distribution, recapitalization, merger, exchange, or replacement, and (ii) “Subscriber” shall include any person to which the rights under this Section 5 shall have been duly assigned.

(g) Pubco shall indemnify, defend and hold harmless Subscriber (to the extent Subscriber is a seller under the Registration Statement), the officers, directors, members, managers, partners, agents and employees of Subscriber, each person who controls Subscriber (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, members, managers, partners, agents and employees of each such controlling person, to the fullest extent permitted by applicable law, from and against any and all out-of-pocket and reasonably documented losses, claims, damages, liabilities, costs (including reasonable and documented external attorneys’ fees) and expenses (collectively, “Losses”) arising out of or caused by or based upon any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any prospectus included in the Registration Statement or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, except to the extent that such untrue statements, alleged untrue statements, omissions or alleged omissions (1) are based upon information regarding Subscriber furnished in writing to Pubco by or on behalf of Subscriber expressly for use therein or Subscriber has omitted a material fact from such information or (2) result from or are in connection with any offers or sales effected by or on behalf of Subscriber in violation of Section 5(d). Notwithstanding the foregoing, Pubco’s indemnification obligations shall not apply to amounts paid in settlement of any Losses or action if such settlement is effected without the prior written consent of Pubco. Pubco shall provide Subscriber with an update on any threatened or asserted proceedings arising from or in connection with the transactions contemplated by this Section 5 of which Pubco receives notice whether oral or in writing.

23

(h) Subscriber shall, severally and not jointly with any other subscriber in the offering contemplated by this Subscription Agreement, indemnify, defend and hold harmless Pubco, its directors, officers, members, managers, partners, agents and employees, each person who controls Pubco (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, members, managers, partners, agents or employees of such controlling persons, to the fullest extent permitted by applicable law, from and against all Losses arising out of or based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement any prospectus included in the Registration Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to 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 any prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under 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 Subscriber furnished in writing to Pubco by or on behalf of Subscriber expressly for use therein. In no event shall the liability of Subscriber be greater in amount than the United States dollars amount of the net proceeds received by Subscriber upon the sale of the Registrable Securities giving rise to such indemnification obligation. Notwithstanding the forgoing, Subscriber’s indemnification obligation shall not apply to amounts paid in settlement of any Losses or action if such settlement is effected without the prior written consent of Subscriber (which consent shall not be unreasonably withheld or delayed).

(i) Any person or entity entitled to indemnification herein shall (i) 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 or entity’s right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, 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 is not entitled to, or 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 any indemnified party a conflict of interest may exist 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), which settlement shall not include a statement or admission of fault and culpability on the part of such indemnified party, and which settlement shall 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.

24

(j) 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 or controlling person or entity of such indemnified party and shall survive the transfer of the Registrable Securities pursuant to this Subscription Agreement.

(k) If the indemnification provided under this Section 5 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any Losses, 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; provided, however, that the liability of Subscriber shall be limited to the net proceeds received by such Subscriber from the sale of Registrable Securities giving rise to such indemnification obligation. 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 not supplied by, in the case of an omission), 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 shall be deemed to include, subject to the limitations set forth in this Section 5, 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 5(k) from any person or entity who was not guilty of such fraudulent misrepresentation. Notwithstanding anything to the contrary herein, in no event will any party be liable for punitive damages in connection with this Subscription Agreement or the transactions contemplated hereby.

(l) At any time and from time to time in connection with a bona-fide sale of Registrable Securities effected in compliance with the requirements of Rule 144 under the Securities Act or through any broker-dealer sale transactions described in the plan of distribution set forth within any prospectus and pursuant to the Registration Statement, Pubco shall use its commercially reasonable efforts, subject to the receipt of customary documentation required from the holder of the applicable Registrable Securities and broker in connection therewith and compliance with applicable laws, (i) promptly instruct its transfer agent to remove any restrictive legends applicable to the Registrable Securities being sold and (ii) in connection with any sale made pursuant to Rule 144, cause its legal counsel to deliver reasonably requested legal opinions, if any, to the transfer agent in connection with the instruction under subclause (i). Subscriber may request that Pubco remove any legend from the book entry position evidencing its Registrable Securities following the earliest of such time as such Registrable Securities (i) (x) are subject to or (y) have been or are about to be sold or transferred pursuant to an effective registration statement (including the Registration Statement), or (ii) have been sold pursuant to Rule 144. Pubco shall be responsible for the fees of its transfer agent, its legal counsel (including for purposes of giving the opinion referenced herein) and all DTC fees associated with such issuance and the Subscriber shall be responsible for its fees or costs associated with such removal of the legend (including its legal fees or costs of its legal counsel).

25

(m) With a view to making available to Subscriber the benefits of Rule 144 that permit Subscriber to sell securities of Pubco to the public without registration, Pubco agrees, for so long as Subscriber holds Registrable Securities, to:

(i) use commercially reasonable efforts to make and keep current public information available, as those terms are understood and defined in Rule 144; and

(ii) use commercially reasonable efforts to file with the Commission in a timely manner all reports and other documents required of Pubco under the Exchange Act so long as Pubco remains subject to such requirements and the filing of such reports and other documents as may be required pursuant to the applicable provisions of Rule 144.

(n) Upon request, Pubco shall provide the Subscriber with contact information for the person responsible for Pubco’s account at the transfer agent to facilitate transfers made pursuant to this Section 5 and provide reasonable assistance to facilitate transfers. Pubco shall be responsible for the fees of its transfer agent and its legal counsel (including for purposes of giving the opinion referenced herein) associated with such issuance and the Subscriber shall be responsible for its fees or costs associated with such removal of the legend (including its legal fees or costs of its legal counsel).

Section 6. Termination. The obligations and restrictions of Section 5 and Section 8(u) of 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 BCA is terminated in accordance with its terms; (b) the mutual written agreement of the parties hereto to terminate this Subscription Agreement or (c) twelve months from the date of this Subscription Agreement; 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 such breach. The Company shall notify Subscriber of the termination of the BCA promptly after the termination thereof.

26

Section 7. Trust Account Waiver. Subscriber hereby acknowledges that SPAC is a blank check company formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses. Subscriber further acknowledges that, as described in the final prospectus relating to SPAC’s initial public offering (“IPO”) filed with the SEC (File No. 333-280719) on November 21, 2024 (the “Prospectus”), substantially all of SPAC’s assets consist of the cash proceeds of SPAC’s IPO and a private placement of its securities and substantially all of those proceeds (including interest accrued from time to time thereon) have been deposited into a trust account (the “Trust Account”) for the benefit of SPAC and its public shareholders. As described in the Prospectus, the funds held from time to time in the Trust Account may only be released upon certain conditions. For good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Subscriber hereby agrees (on its own behalf and on behalf of its related parties) that it does not now and shall not at any time hereafter have any right, title, interest or claim of any kind (“Claim”) to, or to any monies or other assets in, the Trust Account, and hereby irrevocably waives (on its own behalf and on behalf of its related parties) any Claim to, or to any monies or other assets in, the Trust Account that it may have now or in the future as a result of, or arising out of, this Subscription Agreement, the transactions contemplated hereby or the Subscribed Company Exchange Units, in or to any monies held in the Trust Account (or any distributions therefrom directly or indirectly to SPAC’s public shareholders). In the event that Subscriber has any Claim against SPAC as a result of, or arising out of, this Subscription Agreement, the Other LLC Subscription Agreements, the transactions contemplated hereby and thereby, or the Subscribed Company Exchange Units or Pubco Class A Common Stock, Subscriber agrees not to seek recourse against the Trust Account or any funds distributed therefrom (it being clarified that such waiver shall not apply following the closing of the Transactions to the Trust Account funds that are released from the Trust Account to SPAC or Pubco in connection with the Transactions). Subscriber acknowledges and agrees that such irrevocable waiver is a material inducement to SPAC to enter into this Subscription Agreement, and further intends and understands such waiver to be valid, binding, and enforceable against Subscriber in accordance with applicable law. To the extent Subscriber commences any action or proceeding based upon, in connection with, relating to or arising out of any matter relating to SPAC or its Representatives, which proceeding seeks, in whole or in part, monetary relief against SPAC or its Representatives, Subscriber hereby acknowledges and agrees that its sole remedy shall be against funds held outside of the Trust Account and that such claim shall not permit Subscriber (or any person claiming on Subscriber’s behalf or in lieu of Subscriber) to have any claim against the Trust Account (including any distributions therefrom) or any amounts contained therein. Nothing in this Section 7 shall be deemed to limit Subscriber’s right to distributions from the Trust Account in accordance with SPAC’s organizational documents in respect of any redemptions by Subscriber in respect of SPAC Class A Ordinary Shares acquired by any means. Notwithstanding anything in this Subscription Agreement to the contrary, the provisions of this Section 7 shall survive termination of this Subscription Agreement.

Section 8. Miscellaneous.

(a) Subscriber hereby acknowledges that it shall be solely responsible for and bear the cost of all transfer, stamp, issue, registration, documentary or other similar taxes, duties, fees or charges arising in any jurisdiction in connection with the Subscription contemplated in this Subscription Agreement as well as the execution of this Subscription Agreement.

(b) Notwithstanding any other provision of this Subscription Agreement, the Company, Pubco and any of their Representatives shall be entitled to deduct and withhold from the Registrable Securities and any other amount payable pursuant to this Subscription Agreement (in connection with a future share split, dividend, distribution, recapitalization, merger, exchange, or replacement) any such taxes as may be required to be deducted and withheld from such amounts (and any other amounts treated as paid for applicable tax law) under the Internal Revenue Code of 1986, as amended, or any other applicable tax law (as determined in good faith by the party so deducting or withholding in its sole discretion). To the extent that any amounts are so deducted and withheld, such deducted and withheld amounts shall be treated for all purposes of this Subscription Agreement as having been paid to the person in respect of which such deduction and withholding was made.

(d) Subscriber acknowledges that Pubco, the Placement Agent and others, including SPAC and the Company, 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 8(d) shall not give the Company, Pubco or SPAC any rights other than those expressly set forth herein. Prior to the closing of the Transactions, Subscriber agrees to promptly notify the Company, Pubco, SPAC 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. Pubco acknowledges that Subscriber will rely on the acknowledgments, understandings, agreements, representations and warranties contained in this Subscription Agreement. Prior to the closing of the Transactions, the Company and Pubco agree to promptly notify Subscriber, if they become aware that any of the acknowledgments, understandings, agreements, representations and warranties of the Company or Pubco, as applicable, set forth herein are no longer accurate in all material respects.

(e) Each of the Company, Pubco, SPAC, the Placement Agent and Subscriber is irrevocably authorized to produce this Subscription Agreement or a copy hereof to any interested party as required by applicable law in any administrative or legal proceeding or official inquiry with respect to the matters covered hereby.

(f) Each party hereto shall pay all of its own expenses in connection with this Subscription Agreement and the transactions contemplated herein.

28

(g) Neither this Subscription Agreement nor any rights that may accrue to Subscriber hereunder (other than the Subscribed Company Exchange Units acquired hereunder, the Pubco Class A Common Stock acquired upon exchange of the Subscribed Company Exchange Units and the rights set forth in Section 5) may be transferred or assigned by Subscriber. Neither this Subscription Agreement nor any rights or obligations that may accrue to the Company or Pubco hereunder may be transferred or assigned by the Company or Pubco without the prior written consent of Subscriber, other than in connection with the Transactions. Notwithstanding the foregoing, Subscriber may assign all or a portion of 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 Subscriber) upon written notice to the Company, Pubco and SPAC or, with the Company, Pubco and SPAC’s prior written consent, to another person; provided that in the case of any such assignment, the assignee(s) shall become a Subscriber hereunder and have the rights and obligations and be deemed to make the representations and warranties of Subscriber provided for herein to the extent of such assignment; and provided, further, that no such assignment shall relieve the assigning Subscriber of its obligations hereunder if any such assignee fails to perform such obligations, unless the Company, Pubco and SPAC have given their prior written consent to such relief. Any purported assignment or transfer in violation of this Section 8(g) shall be null and void. In the event of such a transfer or assignment, Subscriber shall complete the form of assignment attached as Annex D hereto.

(h) All the agreements, representations and warranties made by each party hereto in this Subscription Agreement shall survive the Subscription Closing.

(i) The Company and Pubco may request from Subscriber such additional information as the Company or Pubco may reasonably determine to be necessary to evaluate the eligibility of Subscriber to acquire the Subscribed Company Exchange Units and to register for resale Pubco Class A Common Stock into which the Subscribed Company Exchange Units are exchangeable, and Subscriber shall promptly provide such information as may be reasonably requested, to the extent readily available and to the extent consistent with its internal policies and procedures; provided that each of the Company and Pubco agrees to keep any such information provided by Subscriber confidential, except (A) as required by the federal securities laws, rules or regulations and (B) to the extent such disclosure is required by other laws, rules or regulations, at the request of the staff of the Commission or regulatory agency or under the regulations of the Stock Exchange. Subscriber acknowledges that SPAC or Pubco may file a form of this Subscription Agreement with the Commission as an exhibit to a current or periodic report of SPAC or Pubco, an annex to a proxy statement of SPAC or Pubco or as an exhibit to a registration statement of Pubco.

(j) 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 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.

(k) 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.

(l) Except with respect to the Placement Agent (who is a third-party beneficiary of the representations, warranties and covenants that reference the Placement Agent set forth herein) or as otherwise provided herein, this Subscription Agreement is intended for the benefit of the parties hereto and their heirs, executors, administrators, successors, legal representatives, and permitted assigns and, except with respect to the Placement Agent or as otherwise as provided herein, is not for the benefit of, nor may any provision hereof be enforced by, any other person.

29

(m) 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 seek 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 the Company and Pubco shall be entitled to specifically enforce Subscriber’s obligations to fund the Subscription 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 8(m) 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.

(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.

(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 electronic mail, in .pdf or other electronic submission) 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 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.

30

(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.

(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 courts of the State of New York or the courts of the United States located in the Borough of Manhattan, New York City, 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 8(c) 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; except with respect to the provisions of this Agreement for which the Placement Agent is an express third party beneficiary.

(u) SPAC shall (i) by 9:00 a.m., New York City time, on the first (1st) business day immediately following the date of the execution of the BCA, issue a press release disclosing the material terms of the transactions contemplated hereby, and (ii) following the execution of the BCA, file with the Commission a “Current Report” on Form 8-K disclosing all material terms of the BCA, this Subscription Agreement, the Other LLC Subscription Agreements and the transactions contemplated hereby and thereby, and the Transactions, and including as exhibits thereto, the BCA, the form of this Subscription Agreement, and the PIPE Subscription Agreements, within the time required by the Exchange Act. From and after the issuance of such press release, SPAC represents to the Subscriber that it shall have publicly disclosed all material, non-public information regarding SPAC delivered to the Subscriber by or on behalf of the SPAC or any of its officers, directors, employees or agents in connection with the transactions contemplated by this Subscription Agreement. Prior to the closing under the BCA, Subscriber shall not issue any press release or make any other similar public statement with respect to the transactions contemplated hereby without the prior written consent of SPAC, the Company and Pubco (such consent not to be unreasonably withheld or delayed). Notwithstanding anything in this Subscription Agreement to the contrary, each of SPAC, the Company and Pubco (i) shall not publicly disclose the name of Subscriber or any of its affiliates or advisers, or include the name of Subscriber or any of its affiliates or advisers in any press release, without the prior written consent of Subscriber and (ii) shall not publicly disclose the name of Subscriber or any of its affiliates or advisers, or include the name of Subscriber or any of its affiliates or advisers in any filing with the Commission or any regulatory agency or trading market, without the prior written consent of Subscriber, except (A) as required by the federal securities laws, rules or regulations, including in connection with the filing of a Registration Statement pursuant to Section 5(a), and (B) to the extent such disclosure is required by other laws, rules or regulations, at the request of the staff of the Commission or regulatory agency or under the regulations of the Stock Exchange, in which case of clause (A) or (B), the Company, SPAC or Pubco, as applicable, shall provide Subscriber with prior written notice (including by e-mail) of such permitted disclosure, and shall reasonably consult with Subscriber regarding such disclosure. Subscriber will promptly provide any information reasonably requested by the Company, SPAC or Pubco for any regulatory application or filing made or approval sought in connection with the Transactions (including filings with the Commission). To the extent that any such information is publicly disclosed pursuant to the provisions hereunder, the parties agree that no further notice or consent is required for SPAC or Pubco to further disclose such information.

31
