	Re:	Initial Public Offering


 


Ladies and Gentlemen:


 


This letter (this “Letter Agreement”)
is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”)
entered into by and among New Beginnings Acquisition Corp. III, a Delaware corporation (the “Company”),
and Ladenburg Thalmann & Co. Inc., as representative (the “Representative”) of the underwriters (the
“Underwriters”), relating to an underwritten initial public offering (the “Public Offering”),
of 11,500,000 of the Company’s units (including up to 1,500,000 units that may be purchased to cover over-allotments, if
any) (the “Units”), each comprised of one share of the Company’s common stock, par value $0.0001
per share (the “Common Stock”), and one redeemable warrant. Each warrant (each, a “Warrant”)
entitles the holder thereof to purchase one share of Common Stock at a price of $11.50 per share, subject to adjustment. The Units
will be sold in the Public Offering pursuant to a registration statement on Form S-1 (File No. 333-248944) and prospectus (as amended,
the “Prospectus”) filed by the Company with the U.S. Securities and Exchange Commission (the “Commission”)
and the Company has applied to have the Units listed on the New York Stock Exchange. Certain capitalized terms used herein
are defined in paragraph 11 hereof.


 


In order to induce the Company and the Underwriters to enter
into the Underwriting Agreement and to proceed with the Public Offering and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, each of New Beginnings Sponsor III, LLC (the “Sponsor”)
and the undersigned individuals, each of whom is a member of the Company’s board of directors and/or management team of the
Company (each, an “Insider” and collectively, the “Insiders”), hereby agrees
with the Company as follows:


 


1. The Sponsor and each Insider agrees that
if the Company seeks stockholder approval of a proposed Business Combination, then in connection with such proposed Business Combination,
it, he or she shall (i) vote any shares of Capital Stock owned by it, him or her in favor of any proposed Business Combination
and (ii) not redeem any shares of Common Stock owned by it, him or her in connection with such stockholder approval. If the Company
engages in a tender offer in connection with any proposed Business Combination, the Sponsor and each Insider agrees that it, he
or she will not seek to sell its, his or her shares of Capital Stock to the Company in connection with such tender offer.


 


2. The Sponsor and
each Insider hereby agrees that in the event that the Company fails to consummate a Business Combination within 24 months from
the closing of the Public Offering, or such later period approved by the Company’s stockholders in accordance with the Company’s
amended and restated certificate of incorporation (the “Charter”), the Sponsor and each Insider shall
take all reasonable steps to cause the Company to (i) cease all operations except for the purpose of winding up, (ii) as promptly
as reasonably possible but not more than ten (10) business days thereafter, subject to lawfully available funds therefor, redeem
100% of the Common Stock sold as part of the Units in the Public Offering (the “Offering Shares”), at
a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account (as defined below), including
interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes (less up to
$100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Offering Shares, which redemption
will completely extinguish all Public Stockholders’ rights as stockholders (including the right to receive further liquidation
distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject
to the approval of the Company’s remaining stockholders and the Company’s board of directors, dissolve and liquidate,
subject in the case of clauses (ii) and (iii) to the Company’s obligations under Delaware law to provide for claims of creditors
and other requirements of applicable law. The Sponsor and each Insider agrees not to propose any amendment to the Charter to modify
(i) the substance or timing of the ability of holders of Offering Shares to seek redemption in connection with a Business Combination
or (ii) (A) the Company’s obligation to redeem 100% of the Offering Shares if the Company does not complete a Business Combination
within such time set forth in the Charter or (B) any other provisions relating to stockholders’ rights or pre-initial Business
Combination activity, unless the Company provides all Public Stockholders with the opportunity to redeem their shares of Common
Stock upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit
in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company
to pay its taxes, divided by the number of then outstanding Offering Shares.


 






     


     


    

 


The Sponsor and each Insider acknowledges
that it, he or she has no right, title, interest or claim of any kind in or to any monies held in the Trust Account or any other
asset of the Company as a result of any liquidation of the Company with respect to the Founder Shares or Private Placement Shares
held by it, him or her. The Sponsor and each Insider hereby further waives, with respect to any shares of Common Stock held by
it, him or her, if any, whether acquired now or hereafter, any redemption rights it, he or she may have in connection with the
consummation of a Business Combination, including, without limitation, any such rights available in the context of a stockholder
vote to approve such Business Combination or a stockholder vote to approve an amendment to the Charter to modify (i) the substance
or timing of the ability of holders of Offering Shares to seek redemption in connection with a Business Combination or (ii) (A)
the Company’s obligation to redeem 100% of the Offering Shares if the Company does not complete a Business Combination within
the time period set forth in the Charter or (B) any other provisions relating to stockholders’ rights or pre-initial Business
Combination activity, unless the Company provides all Public Stockholders with the opportunity to redeem their shares of Common
Stock upon approval of any such amendment at a per share price, payable in cash, equal to the aggregate amount then on deposit
in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company
to pay its taxes, divided by the number of then outstanding Offering Shares, or (ii) in the context of a tender offer made by the
Company to purchase shares of Common Stock (although the Sponsor, the Insiders and their respective affiliates shall be entitled
to redemption and liquidation rights with respect to any Offering Shares it or they hold if the Company fails to consummate a Business
Combination within the time period set forth in the Charter).


 


3. During the period commencing on the date
of the Underwriting Agreement and ending 180 days after such date, the Sponsor and each Insider shall not, without the prior written
consent of the Representative, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase
or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidate
or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended (the
“Exchange Act”), and the rules and regulations of the Commission promulgated thereunder, with respect
to any Units, shares of Capital Stock, Warrants or any securities convertible into, or exercisable, or exchangeable for, shares
of Capital Stock owned by it, him or her, (ii) enter into any swap or other arrangement that transfers to another, in whole or
in part, any of the economic consequences of ownership of any Units, shares of Capital Stock, Warrants or any securities convertible
into, or exercisable, or exchangeable for, shares of Capital Stock owned by it, him or her, whether any such transaction is to
be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction
specified in clause (i) or (ii).


 


4. In the event of the liquidation of the
Trust Account, the undersigned agrees that it will be liable to the Company if and to the extent any claims by a third party (other
than the Company’s independent registered public accounting firm) for services rendered or products sold to the Company,
or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount
of funds in the Trust Account to below the lesser of (i) $10.10 per Offering Share and (ii) the actual amount per Offering Share
held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.10 per Offering Share due to
reductions in the value of the assets in the Trust Account, in each case less interest that may be withdrawn to pay the Company’s
tax obligations, if any; provided that such liability will not apply to any claims by a third party or prospective target
business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable)
nor will it apply to any claims under the Company’s obligation to indemnify the Underwriters against certain liabilities,
including liabilities under the Securities Act of 1933, as amended, pursuant to the Underwriting Agreement. The undersigned acknowledges
and agrees that there will be no distribution from the Trust Account with respect to any Warrants, all rights of which will terminate
on the Company’s liquidation.


 


5. To the extent that the Underwriters do
not exercise the over-allotment option to purchase up to an additional 1,500,000 Units in full within 45 days from the date of
the Prospectus (and as further described in the Prospectus), the Sponsor agrees to forfeit, at no cost, a number of Founder Shares
in the aggregate equal to 375,000 multiplied by a fraction, (i) the numerator of which is 1,500,000 minus the number of Units purchased
by the Underwriters upon the exercise of the over-allotment option, and (ii) the denominator of which is 1,500,000. The Sponsor
will be required to forfeit only that number of Founder Shares as is necessary so that the Initial Stockholders will own an aggregate
of 20.0% of the Company’s issued and outstanding shares of Capital Stock after the Public Offering (not including the Private
Placement Shares).

6. The Sponsor and each Insider hereby agrees
and acknowledges that: (i) the Underwriters and the Company would be irreparably injured in the event of a breach by such Sponsor
or an Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 5, 7(a), 7(b), and 9, as applicable, of this Letter Agreement
(ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching party shall be entitled to injunctive
relief, in addition to any other remedy that such party may have in law or in equity, in the event of such breach.


 


7. (a) The Sponsor and each Insider agrees
that it, he or she shall not Transfer its, his or her Founder Shares until the earlier of (1) one year after the completion of
the Company’s initial Business Combination or (2) the date on which, subsequent to the Company’s initial Business Combination,
(x) the last reported sale price of Common Stock equals or exceeds $12.50 per share (as adjusted for stock splits, stock capitalizations,
reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period or (y) the Company completes
a liquidation, merger, capital stock exchange or other similar transaction that results in all of the Company’s stockholders
having the right to exchange their shares of common stock for cash, securities or other property (the “Founder Shares
Lock-up Period”).


 


(b) The Sponsor and each Insider agrees that it, he
or she shall not Transfer any Private Placement Units, the Private Placement Shares, the Private Placement Warrants or shares of
Common Stock issued or issuable upon the exercise of the Private Placement Warrants, until 30 days after the completion of a Business
Combination (the “Private Placement Units Lock-up Period”, together with the Founder Shares Lock-up Period,
the “Lock-up Periods”).


 


(c) Notwithstanding the provisions set forth in paragraphs
7(a) and (b), Transfers of the Founder Shares, Private Placement Units, Private Placement Shares, Private Placement Warrants and
shares of Common Stock issued or issuable upon the exercise or conversion of the Private Placement Warrants or the Founder Shares
that are held by the Sponsor, any Insider or any of their permitted transferees (that have complied with this paragraph 7(c)),
are permitted (a) to the Company’s officers or directors, any affiliate or family member of any of the Company’s officers
or directors or any affiliate of the Sponsor, any employee of the Sponsor or to any member(s) of the Sponsor or any of their affiliates;
(b) in the case of an individual, by gift to a member of such individual’s immediate family or to a trust, the beneficiary
of which is a member of such individual’s immediate family, an affiliate of such individual or to a charitable organization;
(c) in the case of an individual, by virtue of laws of descent and distribution upon death of any of the Company’s officers,
directors, initial stockholders, or members of the Sponsor; (d) in the case of an individual, pursuant to a qualified domestic
relations order; (e) by private sales or transfers made in connection with the consummation of an initial Business Combination
at prices no greater than the price at which the shares or warrants were originally purchased or otherwise with the consent of
the Company; (f) in the event of the Company’s liquidation prior to the completion of an initial Business Combination; (g)
by virtue of the laws of the State of Delaware or the Sponsor’s limited liability company agreement upon dissolution of the
Sponsor; (h) to the Company for no value for cancellation in connection with the completion of the Business Combination; or (i)
in the event of completion of a liquidation, merger, share exchange or other similar transaction which results in all of the Company’s
stockholders having the right to exchange their shares of Common Stock for cash, securities or other property subsequent to the
completion of a Business Combination; provided, however, that in the case of clauses (a) through (e) or (g), these
permitted transferees must enter into a written agreement with the Company agreeing to be bound by the transfer restrictions herein.
For the avoidance of doubt, the transfers of Founder Shares, Private Placement Units, Private Placement Shares, Private Placement
Warrants and shares of Common Stock issued or issuable upon the exercise or conversion of the Private Placement Warrants or the
Founder Shares shall be permitted regardless of whether a filing under Section 16(a) of the Exchange Act shall be required or shall
be voluntarily made with respect to such transfers.
