of the over-allotment option that is then exercised) at a price of $1.50 per Private Placement Warrant for an aggregate purchase price
of up to $1,500,000 (if the over-allotment option is exercised in full) (the “Over-allotment Purchase Price”).
The Purchaser shall pay the Over-allotment Purchase Price in accordance with the Company’s wire instruction by wire transfer of
immediately available funds to the Company or the Trust Account (as set forth in the wire instructions), at least one (1) business day

with a view towards, or for resale in connection with, any public sale or distribution thereof.


 


(ii)
The Purchaser understands that the Securities are being offered and will be sold to it in reliance on specific exemptions from the registration
requirements of the United States federal and state securities laws and that the Company is relying upon the truth and accuracy of, and
the Purchaser’s compliance with, the representations and warranties of the Purchaser set forth herein in order to determine the
availability of such exemptions and the eligibility of the Purchaser to acquire such Securities.
