		Re:	Initial
Public Offering

 

Gentlemen:

 

This letter is being delivered to you in
accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by and between
Longevity Acquisition Corporation, a British Virgin Islands Company (the “Company”), and Cantor Fitzgerald
 & Co., as Representative (the “Representative”) of the several Underwriters named in Schedule A thereto
(the “Underwriters”), relating to an underwritten initial public offering (the “IPO”)
of the Company’s units (the “Units”), each comprised of one ordinary share, no par value, of the
Company (the “Ordinary Shares”), one warrant (the “Warrant”) to purchase one-half
of one Ordinary Share and one right to receive one-tenth (1/10) of one Ordinary Share upon the consummation of the Company’s
initial business combination (the “Right”). Certain capitalized terms used herein are defined in paragraph
17 hereof.

 

In order to induce
the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the IPO, and in recognition of the
benefit that such IPO will confer upon the undersigned as a shareholder or officer or director of the Company, and for other good
and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned hereby agrees with the
Company as follows:

 

1.     If
the Company solicits approval of its shareholders of a Business Combination (as defined below), the undersigned will vote all Ordinary
Shares beneficially owned by him, her or it, whether acquired before, in or after the IPO, or whether such Ordinary Shares are
underlying the Private Units, in favor of such Business Combination.

 

2.     (a)
In the event that the Company fails to consummate a Business Combination within the time period set forth in the Company’s
Amended and Restated Memorandum and Articles of Association, as the same may be amended from time to time, the undersigned shall
take all reasonable steps to (i) cause the Trust Fund to be liquidated and distributed to the holders of IPO Shares and (ii) cause
the Company to liquidate as soon as reasonably practicable.

 

 (b) The undersigned
hereby waives any and all right, title, interest or claim of any kind (“Claim”) in, or, with respect
to his, her or its Insider Shares or Private Units, to any distribution of, the Trust Fund. The undersigned hereby waives any Claim
the undersigned may have in the future as a result of, or arising out of, any contracts or agreements with the Company and will
not seek recourse against the Trust Fund for any reason whatsoever. The undersigned acknowledges and agrees that there will be
no distribution from the Trust Fund with respect to any Rights or Warrants, which will terminate on the Company’s liquidation.

 

    	 	1	 

     

    

 

 (c) In the event of
the liquidation of the Trust Fund, Whale Management Corporation (“Sponsor”) agrees to indemnify and hold
harmless the Company against any and all loss, liability, claims, damage and expense whatsoever (including, but not limited to,
any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether
pending or threatened, or any claim whatsoever) which the Company may become subject as a result of any claim by any vendor or
other person who is owed money by the Company for services rendered or products sold to or contracted for the Company, or by any
target business with which the Company has discussed entering into a transaction agreement, but only to the extent necessary to
ensure that such loss, liability, claim, damage or expense does not reduce the amount of funds in the Trust Fund to below $10.00
per IPO Share; provided that such indemnity shall not apply if such vendor or other person executes a waiver of
any and all rights to seek access to the Trust Account and except as to claims under the Company’s indemnity of the underwriters
of the IPO against certain liabilities.

 

3.     (a) The Sponsor agrees that it shall
not Transfer any Insider Shares until the earlier until the of  (A) one year after the completion of the Business Combination
or (B) subsequent to the Business Combination, (x) if the last sale price of the Ordinary 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 Business Combination, or (y) the date on which the Company completes
a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of the Company’s
shareholders having the right to exchange their Ordinary Shares for cash, securities or other property

 

 (b) The Sponsor agrees that it shall not
effectuate any Transfer of securities issued or issuable upon the exercise of the Private Units or their underlying securities
until 30 days after the completion of the Business Combination.

 

 (c) Notwithstanding the provisions set
forth in paragraphs 3(a) and (b), Transfers of the Insider Shares, securities issued or issuable upon the exercise of the Private
Units or their underlying securities, and that are held by the Sponsor, any Insider or any of their permitted transferees (that
have complied with this paragraph 3(c)), are permitted (1) to any persons (including their affiliates and shareholders) participating
in the private placement of the Private Units, officers, directors, shareholders, employees and members of the Sponsor and its
affiliates, (2) amongst initial holders or to the Company’s officers, directors and employees, (3) if a holder is an entity,
as a distribution to its, partners, shareholders or members upon its liquidation, (4) by bona fide gift to a member of the holder’s
immediate family or to a trust, the beneficiary of which is a holder or a member of a holder’s immediate family, for estate
planning purposes, (5) by virtue of the laws of descent and distribution upon death, (6) pursuant to a qualified domestic relations
order, (7) by certain pledges to secure obligations incurred in connection with purchases of the Company’s securities, (8)
by private sales at prices no greater than the price at which the applicable securities were originally purchased or (9) to the
Company for no value for cancellation in connection with the consummation of the Business Combination, in each case (except for
clause 9) where the transferee agrees to the terms of this letter agreement and by the same agreements entered into by the Sponsor
with respect to such securities.

 

4.     [Intentionally
Omitted].

 

5.     In
order to minimize potential conflicts of interest which may arise from multiple affiliations, the undersigned directors and officers
of the Company agree to present to the Company for its consideration, prior to presentation to any other person or entity, any
suitable opportunity to acquire a target business, until the earlier of the consummation by the Company of a Business Combination
or the liquidation of the Company, subject to any pre-existing fiduciary and contractual obligations the undersigned directors
and officers might have.

 

6.    The
undersigned acknowledges and agrees that prior to entering into a Business Combination with a target business that is affiliated
with any Insiders of the Company or their affiliates, such transaction must be approved by a majority of the Company’s disinterested
independent directors and the Company must obtain an opinion from an independent investment banking firm or independent accounting
firm that such Business Combination is fair to the Company’s unaffiliated shareholders from a financial point of view.

 

    	 	2	 

     

    

 

7.     Neither

action, suit or other proceeding brought against the Trustee involving any claim, or in connection with any claim or demand which

any provisions of its Memorandum and Articles of Association relating to shareholders’ rights or pre-Business Combination
activity (including the substance and time within which the Company has to complete a Business Combination) (in each case, an “Amendment”),
the Company will provide the Trustee with a letter (an “Amendment Notification Letter”) in the form of Exhibit E providing
instructions for the distribution of funds to Public Stockholders who exercise their redemption option in connection with such
Amendment;

 

(h)     If applicable, issue a press
release at least three days prior to the Applicable Deadline announcing that, at least five days prior to the Applicable Deadline,

effectiveness of its provisions, but also as and with reasonable care to the truth and acceptability of any information therein

to, or to any monies in, the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account

or with the United States District Court for the Southern District of New York and upon such deposit, the Trustee shall be immune
from any liability whatsoever; or

 

(b)     At such time that the Trustee

the Property in accordance with the provisions of the Termination Letter, this Agreement shall terminate except with respect to
