 4.4.
Registration Rights. The Purchaser will be entitled to certain registration rights with respect to the Placement Securities held by it which will be governed by a registration rights agreement (“Registration Rights

“Business Combination”), except to permitted transferees (as defined in the Insider Letter).

{N0405972} 

 8. Rescission Right Waiver and Indemnification 

8.1. Rescission Waiver. The Purchaser understands and acknowledges that an exemption from the registration requirements of the
Securities Act requires there be no general solicitation of purchasers of the Units. In this regard, if the Offering were deemed to be a general solicitation with respect to the Units, the offer and sale of such Units may not be exempt from
registration and, if not, the Purchaser may have a right to rescind its purchase of the Units. In order to facilitate the completion of the Offering and in order to protect the Company, its shareholders and the Trust Account from claims that may
adversely affect the Company or the interests of its shareholders, the Purchaser hereby agrees to waive, to the maximum extent permitted by applicable law, any claims, right to sue or rights in law or arbitration, as the case may be, to seek
rescission of its purchase of the Units as a result of the issuance of the Units being deemed to be in violation of Section 5 of the Securities Act. The Purchaser acknowledges and agrees this waiver is being made in order to induce the Company
to sell the Units to the Purchaser. The Purchaser agrees the foregoing waiver of rescission rights shall apply to any and all known or unknown actions, causes of action, suits, claims or proceedings (collectively,
“Claims”) and related losses, costs, penalties, fees, liabilities and damages, whether compensatory, consequential or exemplary, and expenses in connection therewith, including reasonable attorneys’ and expert
witness fees and disbursements and all other expenses reasonably incurred in investigating, preparing or defending against any Claims, whether pending or threatened, in connection with any present or future actual or asserted right to rescind the
purchase of the Units hereunder or relating to the purchase of the Units and the transactions contemplated hereby. 
 8.2.
Section 8 Waiver. The Purchaser agrees that to the extent any waiver of rights under this Section 8 is ineffective as a matter of law, the Purchaser has offered such waiver for the benefit of the Company as an
equitable right that shall survive any statutory disqualification or bar that applies to a legal right. The Purchaser acknowledges the receipt and sufficiency of consideration received from the Company hereunder in this regard. 

9. Terms of the Private Units 

The Private Units shall be substantially identical to the Units offered in the IPO as set forth in the Underwriting Agreement, except the
Private Units and component parts: (i) will be subject to the transfer restrictions described herein and in the Insider Letter, and (ii) are being purchased pursuant to an exemption from the registration requirements of the Securities Act
and will become freely tradable only after expiration of the lockup described above and certain conditions are met or the resale of the Placement Securities is registered under the Securities Act. Each Placement Warrant shall have the terms set
forth in the Warrant Agreement. 
 10. Governing Law; Jurisdiction; Waiver of Jury Trial 

This Agreement shall be governed by and construed in accordance with the laws of the State of New York for agreements made and to be wholly
performed within such territory. The parties hereto hereby waive any right to a jury trial in connection with any litigation pursuant to this Agreement and the transactions contemplated hereby.

for herein to the extent of such assignment.

understanding between the parties as to the subject matter hereof and supersedes any and all prior discussions, agreements and understandings of any and every nature.

discharged or terminated other than by a written instrument signed by the party against whom enforcement of any such amendment, waiver, discharge or termination is sought.

respective heirs, legal representatives, successors and permitted assigns.
