RECITALS

WHEREAS, SPAC, the Company and certain other Persons party thereto are entering into a Business Combination Agreement, dated as of the date hereof (as it may be amended, restated or otherwise modified from time to time in accordance with its terms, the “Business Combination Agreement”).

AGREEMENT

NOW, THEREFORE, in consideration of the premises and the mutual promises contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties, each intending to be legally bound, hereby agree as follows:

1. Agreement to Vote. During the period commencing on the date hereof and ending on the earlier of (i) the Initial Closing and (ii) such date and time as the Business Combination Agreement shall be terminated in accordance with Section 10.1 thereof, the Class B Holder, in their individual capacity as a shareholder of SPAC, hereby irrevocably agrees, at any meeting of the shareholders of SPAC duly called and convened in accordance with the Organizational Documents of SPAC, whether or not adjourned and however called, including at the SPAC Shareholders’ Meeting or otherwise, and in any action by written consent of the SPAC Shareholders, (i) to vote, or cause to be voted, or execute and return, or cause to be executed and returned, an action by written consent with respect to, as applicable, all of their SPAC Shares held of record or beneficially by the Class B Holder as of the date of this Agreement, as set forth in Exhibit A, or to which the Class B Holder acquires record or beneficial ownership after the date hereof and prior to the Initial Closing (collectively, the “Subject SPAC Equity Securities”) in favor of each of the Transaction Proposals, in each case, to the extent the Subject SPAC Equity Securities are entitled to vote thereon or consent thereto, (ii) when such meeting is held, appear at such meeting or otherwise cause the Subject SPAC Equity Securities to be counted as present thereat for the purpose of establishing a quorum, (iii) to the fullest extent permitted under applicable Law, waive any dissenters, appraisal or other similar rights, whether such rights are afforded by Law or contract, in respect of the transactions contemplated by the Business Combination Agreement (the “Transactions”) and the Transaction Documents, including the Initial Merger, and (iv) to vote against, or cause to be voted against, or withhold consent, or cause consent to be withheld, with respect to, as applicable, (A) any SPAC Acquisition Proposal or (B) transactions that would materially impede the consummation of the Transactions.

2. Waiver of Anti-Dilution Protection. The Class B Holder hereby (a) waives, subject to, and conditioned upon, the occurrence of the Initial Closing (for itself and for its successors, heirs and assigns), and (b) agrees not to assert or perfect, any rights to adjustment or other anti-dilution protections with respect to the rate that the SPAC Class B Ordinary Shares held by them convert into SPAC Class A Ordinary Shares, including those set out in Article 17 of the Amended and Restated Memorandum and Articles of Association of SPAC, in connection with the Transactions or otherwise. SPAC hereby acknowledges and agrees to such waiver. For the avoidance of doubt in connection with the Transactions, the SPAC Class B Ordinary Shares shall convert into SPAC Class A Ordinary Shares on a one-to-one basis.

3. Transfer of Lock-Up Shares.

(a) Except with the prior written consent of the Company before the Acquisition Closing, and PubCo following the Acquisition Closing (such consent to be given or withheld in its sole discretion), the Class B Holder agrees that it will not Transfer any SPAC Class B Ordinary Shares (or any PubCo Common Shares issuable upon conversion thereof) until the earlier of (i) twelve (12) months after the Acquisition Closing and (ii) following the Acquisition Closing (x) if the closing price of the PubCo Common Shares equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Acquisition Closing or (y) the date on which PubCo (or its successor) completes a liquidation, merger, amalgamation, capital stock exchange, reorganization or other similar transaction that results in all of PubCo’s (or such successor’s) shareholders having the right to exchange their PubCo Common Shares for cash, securities or other property (the “Lock-Up Period”). “Transfer” means the (a) sale of, offer to sell, contract or agreement to sell, hypothecate, pledge, grant of any option to purchase or otherwise dispose of or agreement to dispose of, directly or indirectly, or establishment or increase of a put equivalent position or liquidation with respect to or decrease of a call equivalent position within the meaning of Section 16 of the Exchange Act, and the rules and regulations of the SEC promulgated thereunder with respect to, any security, (b) entry into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any security, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (c) public announcement of any intention to effect any transaction specified in clause (a) or (b).

(b) Notwithstanding the provisions set forth in paragraph 3(a), Transfers of the SPAC Class B Ordinary Share (or any PubCo Common Shares issuable upon conversion thereof) that are held by the Class B Holder is permitted (a) to the SPAC’s officers or directors, any affiliate or family member of any of the SPAC’s officers or directors, any affiliate of the Sponsor or to any members of the Sponsor or any of their affiliates; (b) by gift to a member of the Class B Holder’s immediate family or to a trust, the beneficiary of which is a member of such Class B Holder’s immediate family, an affiliate of such individual or to a charitable organization; (c) by virtue of laws of descent and distribution upon death of such Class B Holder; (d)  pursuant to a qualified domestic relations order; (e) by private sales or transfers made in connection with any forward purchase agreement or similar arrangement or in connection with the Acquisition Closing at prices no greater than the price at which the securities were originally purchased; or (f) in the event of the SPAC’s liquidation prior to the completion of an initial business combination; provided, however, that in the case of clauses (a) through (e), these permitted transferees must enter into a written agreement with PubCo agreeing to be bound by the transfer restrictions herein.

4. Other Agreements.

(a) The Class B Holder understands and acknowledges that (i) SPAC, PubCo and the Company are entering into the Business Combination Agreement in reliance on the Class B Holder entering into this Agreement and agreeing to be bound by, and perform, or otherwise comply with, as applicable, the agreements, covenants and obligations contained in this Agreement and (ii) but for the Class B Holder entering into this Agreement and agreeing to be bound by, and perform, or otherwise comply with the agreements, covenants and obligations contained in this Agreement, the SPAC, PubCo and the Company would not have entered into the Business Combination Agreement.

(b) The Class B Holder hereby agrees that that certain Registration Rights Agreement, dated January 26, 2021, by and among SPAC, Constellation Sponsor GmbH & Co. KG, a German limited partnership and the other parties thereto will terminate in connection with the Initial Closing.

(b) No consent, approval or authorization of, or designation, declaration or filing with, any Governmental Authority is required on the part of the Class B Holder with respect to the Class B Holder’s execution, delivery or performance of its covenants, agreements or obligations under this Agreement (including, for the avoidance of doubt, those covenants, agreements and obligations under this Agreement that relate to the provisions of the Business Combination Agreement) or the consummation of the Transactions contemplated hereby, except for any consents, approvals, authorizations, designations, declarations, waivers or filings, the absence of which would not prevent or materially impair the ability of the Class B Holder to perform, or otherwise comply with, any of its covenants, agreements or obligations hereunder in any material respect.

(c) None of the execution or delivery of this Agreement by the Class B Holder, the performance by the Class B Holder of any of its covenants, agreements or obligations under this Agreement (including, for the avoidance of doubt, those covenants, agreements and obligations under this Agreement that relate to the provisions of the Business Combination Agreement) or the consummation of the transactions contemplated hereby will, directly or indirectly (with or without due notice or lapse of time or both) (i) result in a violation or breach of, or constitute a default or give rise to any right of termination, consent, cancellation, amendment, modification, suspension, revocation or acceleration under, any of the terms, conditions or provisions of any Contract to which the Class B Holder is a party, (ii) violate, or constitute a breach under, any Governmental Order or applicable Law to which the Class B Holder or any of their properties or assets are bound or (iii) result in the creation of any Encumbrance upon their Subject SPAC Equity Securities, except, in the case of any of clauses (i) through (iii) above, as would not prevent or materially impair the ability of the Class B Holder to perform, or otherwise comply with, any of their covenants, agreements or obligations hereunder in any material respect.

(e) There is no Action pending or, to the Class B Holder’s knowledge, threatened in writing against or involving any Class B Holder or any of their Affiliates that, if adversely decided or resolved, would reasonably be expected to prevent or materially impair the ability of the Class B Holder to perform, or otherwise comply with, any of its covenants, agreements or obligations under this Agreement in any material respect or consummate the transactions contemplated by the Business Combination Agreement.

9. Amendments and Waivers; Assignment. Any provision of this Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed by each Party hereto. Notwithstanding the foregoing, no failure or delay by any Party in exercising any right hereunder will operate as a waiver thereof nor will any single or partial exercise thereof preclude any other or further exercise of any other right hereunder. Neither this Agreement nor any of the rights, interests or obligations hereunder will be assignable by any Party without the other Party’s prior written consent (to be withheld or given in its sole discretion). Any attempted assignment of this Agreement not in accordance with the terms of this Section 9 will be void.
