purposes only and not with a view towards, or for resale in connection with, any public sale or distribution thereof.

 

(ii)             
Such Purchaser is an “accredited investor” as such term is defined in Rule 501(a)(3) of Regulation D under
the Securities Act.

 

(iii)            
Such 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 such Purchaser’s compliance with, the representations and warranties of such Purchaser set forth herein in
order to determine the availability of such exemptions and the eligibility of such Purchaser to acquire such Securities.

Such Purchaser understands that no United States federal or state agency or any other government or governmental agency

will not be available for resale transactions of Securities prior to a Business Combination and may not be available for resale transactions
of Securities after a Business Combination.

Such Purchaser has such knowledge and experience in financial and business matters, knows of the high degree of risk associated
with investments in the securities of companies in the development stage such as the Company, is capable of evaluating the merits and
risks of an investment in the Securities and is able to bear the economic risk of an investment in the Securities in the amount contemplated
hereunder for an indefinite period of time. Such Purchaser has adequate means of providing for its current financial needs and contingencies
and will have no current or anticipated future needs for liquidity which would be jeopardized by the investment in the Securities. Such
Purchaser can afford a complete loss of its investment in the Securities.

purposes only and not with a view towards, or for resale in connection with, any public sale or distribution thereof.

 

(ii)           Such
Purchaser is an “accredited investor” as such term is defined in Rule 501(a)(3) of Regulation D under the Securities Act.

 

(iii)          Such
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
such Purchaser’s compliance with, the representations and warranties of such Purchaser set forth herein in order to determine the
availability of such exemptions and the eligibility of such Purchaser to acquire such Securities.

 

(iv)          Such

to ask questions of the executive officers and directors of the Company. Such Purchaser understands that its investment in the Securities

(vi)          Such
Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed on or made

transactions of Securities prior to a Business Combination and may not be available for resale transactions of Securities after a Business
Combination.

Purchaser has such knowledge and experience in financial and business matters, knows of the high degree of risk associated with investments
in the securities of companies in the development stage such as the Company, is capable of evaluating the merits and risks of an investment
in the Securities and is able to bear the economic risk of an investment in the Securities in the amount contemplated hereunder for an
indefinite period of time. Such Purchaser has adequate means of providing for its current financial needs and contingencies and will
