Exhibit 4.1


 


WARRANT AGREEMENT


 


THIS WARRANT AGREEMENT (this
 “Agreement”), dated as of October 27, 2021, is by and between Seaport Calibre Materials Acquisition Corp., a
Delaware corporation (the “Company”), and Continental Stock Transfer & Trust Company, a New York corporation,
as warrant agent (the “Warrant Agent”, also referred to herein as the “Transfer Agent”).


 


WHEREAS, the Company is engaged
in an initial public offering (the “Offering”) of units of the Company’s equity securities, each such
unit comprised of one share of Class A common stock of the Company, par value $0.0001 per share (“Common Stock”)
and one-half of one redeemable Public Warrant (as defined below) (the “Units”) and, in connection therewith,
has determined to issue and deliver up to 6,500,000 warrants (or up to 7,475,000 warrants if the Over-allotment Option is exercised
in full) to public investors in the Offering (the “Public Warrants”);


 


WHEREAS, on October 27, 2021,
the Company entered into Private Placement Warrants Purchase Agreements with each of Seaport Global Asset Management, LLC, a Delaware
limited liability company (“SGAM”), Calibre Group, LLC, a Delaware limited liability company (“Calibre”),
together with their controlled affiliates, (collectively, the “Sponsors”) pursuant to which the Initial Stockholders
committed to subscribe to purchase an aggregate of 4,700,000 warrants, (or up to 5,090,000 warrants in the event that the Over-allotment
Option (as defined below) in connection with the Company’s Offering is exercised in full) simultaneously with the closing of the
Offering bearing the legend set forth in Exhibit B hereto (the “Private Placement Warrants”) at
a purchase price of $1.50 per Private Placement Warrant;


 


WHEREAS, in order to finance
the Company’s transaction costs in connection with an intended initial Business Combination (as defined below), certain of the Company’s
Initial Stockholders may, but are not obligated to, loan to the Company funds as the Company may require, of which up to $2,000,000 of
such loans may be convertible into up to an additional 2,000,000 warrants at a price of $1.50 per warrant (the “Working
Capital Warrants”);


 


WHEREAS, following consummation
of the Offering, the Company may issue additional warrants (“Post IPO Warrants”; together with the Private Placement
Warrants, the Working Capital Warrants and the Public Warrants, the “Warrants”) in connection with, or following
the consummation by the Company of, a Business Combination (defined below);


 


WHEREAS, the Company has filed
with the U.S. Securities and Exchange Commission (the “Commission”) a registration statement on Form S-1,
File No. 333-258024 (the “Registration Statement”) and prospectus (the “Prospectus”),
for the registration, under the Securities Act of 1933, as amended (the “Securities Act”), of the Units,
the Public Warrants and the Common Stock included in the Units;


 


WHEREAS, the Company desires
the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with the issuance, registration,
transfer, exchange, redemption and exercise of the Warrants;


 


WHEREAS, the Company desires
to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and exercised, and the respective rights,
limitation of rights, and immunities of the Company, the Warrant Agent, and the holders of the Warrants; and


 


WHEREAS, all acts and things
have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company and countersigned by or
on behalf of the Warrant Agent, as provided herein, the valid, binding and legal obligations of the Company, and to authorize the execution
and delivery of this Agreement.


 


NOW, THEREFORE, in consideration
of the mutual agreements herein contained, the parties hereto agree as follows:


 









     


     


    

 


1.                  
 Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company for the Warrants,
and the Warrant Agent hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth
in this Agreement.


 


2.                  
Warrants.


 


2.1               
Form of Warrant. Each Warrant shall be issued in registered form only, and, if a physical certificate is issued, shall be
in substantially the form of Exhibit A hereto, the provisions of which are incorporated herein and shall be signed by, or
bear the facsimile signature of, the Chairman of the Board, President, Chief Executive Officer, Chief Financial Officer, Secretary or
other principal officer of the Company. In the event the person whose facsimile signature has been placed upon any Warrant shall have
ceased to serve in the capacity in which such person signed the Warrant before such Warrant is issued, it may be issued with the same
effect as if he or she had not ceased to be such at the date of issuance.


 


2.2               
Effect of Countersignature. If a physical certificate is issued, unless and until countersigned by the Warrant Agent pursuant
to this Agreement, a Warrant certificate shall be invalid and of no effect and may not be exercised by the holder thereof.


 


2.3               
Registration.


 


2.3.1          
Warrant Register. The Warrant Agent shall maintain books (the “Warrant Register”) for the registration
of original issuance and the registration of transfer of the Warrants. Upon the initial issuance of the Warrants, the Warrant Agent shall
issue and register the Warrants in the names of the respective holders thereof in such denominations and otherwise in accordance with
instructions delivered to the Warrant Agent by the Company. All of the Public Warrants shall initially be represented by one or more book-entry
certificates (each, a “Book-Entry Warrant Certificate”) deposited with The Depository Trust Company (the “Depositary”)
and registered in the name of Cede & Co., a nominee of the Depositary. Ownership of beneficial interests in the Public Warrants shall
be shown on, and the transfer of such ownership shall be effected through, records maintained by (i) the Depositary or its nominee
for each Book-Entry Warrant Certificate, or (ii) institutions that have accounts with the Depositary (each such institution, with
respect to a Warrant in its account, a “Participant”).


 


If the Depositary subsequently
ceases to make its book-entry settlement system available for the Public Warrants, the Company may instruct the Warrant Agent regarding
making other arrangements for book-entry settlement. In the event that the Public Warrants are not eligible for, or it is no longer necessary
to have the Public Warrants available in, book-entry form, the Warrant Agent shall provide written instructions to the Depositary to deliver
to the Warrant Agent for cancellation each Book-Entry Warrant Certificate, and the Company shall instruct the Warrant Agent to deliver
to the Depositary definitive certificates in physical form evidencing such Warrants (“Definitive Warrant Certificate”).
Such Definitive Warrant Certificate shall be in the form annexed hereto as Exhibit A, with appropriate insertions, modifications
and omissions, as provided above.


 


2.3.2          
Registered Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent
may deem and treat the person in whose name such Warrant is registered in the Warrant Register (the “Registered Holder”)
as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of ownership or other writing
on a Definitive Warrant Certificate made by anyone other than the Company or the Warrant Agent), for the purpose of any exercise thereof,
and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.


 


2.4                Detachability
of Warrants. The Common Stock and Public Warrants comprising the Units shall begin separate trading on the 52nd day
following the date of the Prospectus or, if such 52nd day is not on a day, other than a Saturday, Sunday or federal holiday, on
which banks in New York City are generally open for normal business (a “Business Day”), then on the
immediately succeeding Business Day following such date, or earlier (the “Detachment Date”) with the
consent of Seaport Global Securities LLC, as representative of the several underwriters (the
 “Representative”), but in no event shall the Common Stock and the Public Warrants comprising the Units be
separately traded until (A) the Company has filed a current report on Form 8-K with the Commission containing an audited
balance sheet reflecting the receipt by the Company of the gross proceeds of the Offering, including the proceeds received by the
Company from the exercise by the underwriters of their right to purchase additional Units in the Offering (the
 “Over-Allotment Option”), if the Over-Allotment Option is exercised prior to the filing of the
Form 8-K, and (B) the Company issues a press release and files with the Commission a current report on Form 8-K
announcing when such separate trading shall begin.


 






     


     


    

 


2.5               
No Fractional Warrants Other Than as Part of Units. The Company shall not issue fractional Warrants other than as part of
the Units, each of which is comprised of one share of Common Stock and one-half of one Public Warrant. If, upon the detachment of Public
Warrants from Units or otherwise, a holder of Warrants would be entitled to receive a fractional Warrant, the Company shall round down
to the nearest whole number the number of Warrants to be issued to such holder.


 


2.6               
Private Placement Warrants and Working Capital Warrants. The Private Placement Warrants and the Working Capital Warrants
shall be identical to the Public Warrants, except that so long as they are held by the Sponsors or any Permitted Transferees (as defined
below), as applicable, the Private Placement Warrants and the Working Capital Warrants: (i) may be exercised for cash or on a cashless
basis, pursuant to subsection 3.3.1(c) hereof, (ii) may not be transferred, assigned or sold until (x) thirty (30) days
after the completion by the Company of an initial Business Combination (as defined below) or (y) in compliance with FINRA Rule 5110(e),
to the extent such date falls within the 180-day period immediately following commencement of sales of the Offering, after the 180-day
period immediately following commencement of sales of the Offering, subject to certain exceptions permitted by FINRA Rule 5110(e)(2),
(iii) will not be exercisable more than five years from the effective date of the Registration Statement in accordance with FINRA
Rule 5110(g)(8), as long as they are beneficially owned by SGAM or any of its related persons, and (iv) shall not be redeemable
by the Company; provided, however, that in the case of (ii) the Private Placement Warrants and the Working Capital
Warrants and any shares of Common Stock held by the Sponsors or any Permitted Transferees, as applicable, and issued upon exercise of
the Private Placement Warrants and the Working Capital Warrants may be transferred by the holders thereof:


 


(a)                
to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors,
any members of the Company’s Sponsors, or any affiliates of the Company’s Sponsors;


 


(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 the laws of descent and distribution upon death of such person;


 


(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 Warrants were originally purchased;


 


(f)                 
in the event of the Company’s liquidation prior to consummation of the Company’s Business Combination;


 


(g)               
by virtue of the laws of Delaware or the Company’s sponsors’ limited liability company agreement upon dissolution of
the Sponsors; or


 


(h)               
in the event of the Company’s liquidation, merger, capital stock exchange, reorganization 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 Company’s completion of the Company’s initial business combination;


 


provided, however, that
(i) the 2,666,667 private placement warrants acquired by SGAM and certain of its controlled affiliates, which have been
deemed underwriting compensation by FINRA, will not be sold during the offering, or sold, transferred, assigned, pledged, or
hypothecated, or be the subject of any hedging, short sale, derivative, put or call transaction that would result in the economic
disposition of such securities by any person for a period of 180 days immediately following the sales of the public
offering, subject to certain exceptions permitted by FINRA Rule 5110(e)(2), and (ii) in the case of clauses (a)
through (e) or (g), these transferees (the “Permitted Transferees”) enter into a written agreement
with the Company agreeing to be bound by the transfer restrictions in this Agreement.


 






     


     


    

 


2.7               
Working Capital Warrants. The Working Capital Warrants shall be identical to the Private Placement Warrants.


 


2.8               
Post-IPO Warrants. The Post-IPO Warrants, when and if issued, shall have the same terms and be in the same form as the Public
Warrants except as may be agreed upon by the Company.


 


3.                  
Terms and Exercise of Warrants.


 


3.1               
Warrant Price. Each whole Warrant shall entitle the Registered Holder thereof, subject to the provisions of such Warrant
and of this Agreement, to purchase from the Company the number of shares of Common Stock stated therein, at the price of $11.50 per
share, subject to the adjustments provided in Section 4 hereof and in the last sentence of this Section 3.1. The
term “Warrant Price” as used in this Agreement shall mean the price per share at which shares of Common Stock may be purchased
at the time a Warrant is exercised. The Company in its sole discretion may lower the Warrant Price at any time prior to the Expiration
Date (as defined below) for a period of not less than twenty (20) Business Days; provided, that the Company shall provide at least
five (5) days’ prior written notice of such reduction to Registered Holders of the Warrants; and provided further, that any
such reduction shall be identical among all of the Warrants.


 


3.2               
Duration of Warrants. A Warrant may be exercised only during the period (the “Exercise Period”)
commencing on the later of: (i) the date that is thirty (30) days after the first date on which the Company completes a merger,
capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination, involving the Company and one
or more businesses (a “Business Combination”), or (ii) (x) the date that is five (5) years after the
date on which the Company completes its initial Business Combination, (y) the liquidation of the Company, or (z) other than
with respect to the Private Placement Warrants and the Working Capital Warrants to the extent then held by the original purchasers thereof
or their Permitted Transferees, the Redemption Date (as defined below) as provided in Section 6.3 hereof (the Expiration
Date”); provided, however, that the exercise of any Warrant shall be subject to the satisfaction of any applicable
conditions, as set forth in subsection 3.3.2 below, with respect to an effective registration statement. Except with respect
to the right to receive the Redemption Price (as defined below) (other than with respect to a Private Placement Warrant or a Working Capital
Warrant) to the extent then held by the original purchasers thereof or their Permitted Transferees in the event of a redemption (as set
forth in Section 6 hereof), each outstanding Warrant (other than a Private Placement Warrant or a Working Capital Warrant
to the extent then held by the original purchasers thereof or their Permitted Transferees in the event of a redemption) not exercised
on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall
cease at 5:00 p.m. New York City time on the Expiration Date. The Company in its sole discretion may extend the duration of the Warrants
by delaying the Expiration Date; provided, that the Company shall provide at least twenty (20) days prior written notice of
any such extension to Registered Holders of the Warrants and, provided further that any such extension shall be identical in duration
among all the Warrants.


 


3.3               
Exercise of Warrants.


 


3.3.1           Payment.
Subject to the provisions of the Warrant and this Agreement, a Warrant may be exercised by the Registered Holder thereof by
delivering to the Warrant Agent at its corporate trust department (i) the Definitive Warrant Certificate evidencing the
Warrants to be exercised, or, in the case of a Book-Entry Warrant Certificate, the Warrants to be exercised (the
 “Book-Entry Warrants”) on the records of the Depositary to an account of the Warrant Agent at the
Depositary designated for such purposes in writing by the Warrant Agent to the Depositary from time to time, (ii) an election
to purchase (“Election to Purchase”) shares of Common Stock pursuant to the exercise of a Warrant,
properly completed and executed by the Registered Holder on the reverse of the Definitive Warrant Certificate or, in the case of a
Book-Entry Warrant Certificate, properly delivered by the Participant in accordance with the Depositary’s procedures, and
(iii) payment in full of the Warrant Price for each full share of Common Stock as to which the Warrant is exercised and any and
all applicable taxes due in connection with the exercise of the Warrant, the exchange of the Warrant for the shares of Common Stock
and the issuance of such shares of Common Stock, as follows:


 






     


     


    

 


(a)                
in lawful money of the United States, in good certified check or good bank draft payable to the Warrant Agent or by wire of immediately
available funds;


 


(b)               
in the event of a redemption pursuant to Section 6 hereof in which the Company’s board of directors (the “Board”)
has elected to require all holders of the Warrants to exercise such Warrants on a “cashless basis,” by surrendering the Warrants
for that number of shares of Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common
Stock underlying the Warrants, multiplied by the difference between the Warrant Price and the “Fair Market Value”, as defined
in this subsection 3.3.1(b) by (y) the Fair Market Value. Solely for purposes of this subsection 3.3.1(b)
and Section 6.4, the “Fair Market Value” shall mean the volume weighted average price of the Company’s Common
Stock for the ten (10) trading days ending on the third trading day prior to the date on which the notice of redemption is sent to
the holders of the Warrants, pursuant to Section 6 hereof;


 


(c)                
with respect to any Private Placement Warrant or Working Capital Warrant, so long as such Private Placement Warrant or Working
Capital Warrant is held by our Sponsors or a Permitted Transferee, as applicable, by surrendering the Warrants for that number of shares
of Common Stock equal to (i) if in connection with a redemption of Private Placement Warrants pursuant to Section 6.2
hereof, as provided in Section 6.2 hereof with respect to a Make-Whole Exercise (as defined below) and (ii) in all other
scenarios the quotient obtained by dividing (x) the product of the number of shares of Common Stock underlying the Warrants, multiplied
by the difference between the Warrant Price and the “Fair Market Value”, as defined in this subsection 3.3.1(c),
by (y) the Fair Market Value. Solely for purposes of this subsection 3.3.1(c), the “Fair Market Value” shall
mean the average reported last sale price of the Common Stock for the ten (10) trading days ending on the third trading day prior
to the date on which notice of exercise of the Warrant is sent to the Warrant Agent;


 


(d)               
as provided in Section 6.2 hereof with respect to a Make-Whole Exercise; or


 


(e)                
as provided in Section 7.4 hereof.


 


3.3.2           Issuance
of Shares of Common Stock on Exercise. As soon as practicable after the exercise of any Warrant and the clearance of the funds
in payment of the Warrant Price (if payment is pursuant to subsection 3.3.1(a)), the Company shall issue to the
Registered Holder of such Warrant a book-entry position or certificate, as applicable, for the number of full shares of Common Stock
to which he, she or it is entitled, registered in such name or names as may be directed by him, her or it, and if such Warrant shall
not have been exercised in full, a new book-entry position or countersigned Warrant, as applicable, for the number of shares of
Common Stock as to which such Warrant shall not have been exercised. If fewer than all the Warrants evidenced by a Book-Entry
Warrant Certificate are exercised, a notation shall be made to the records maintained by the Depositary, its nominee for each
Book-Entry Warrant Certificate, or a Participant, as appropriate, evidencing the balance of the Warrants remaining after such
exercise. Notwithstanding the foregoing, the Company shall not be obligated to deliver any shares of Common Stock pursuant to the
exercise of a Warrant and shall have no obligation to settle such Warrant exercise unless a registration statement under the
Securities Act with respect to the shares of Common Stock underlying the Public Warrants is then effective and a prospectus relating
thereto is current, subject to the Company’s satisfying its obligations under Section 7.4. No Warrant shall be
exercisable and the Company shall not be obligated to issue shares of Common Stock upon exercise of a Warrant unless the Common
Stock issuable upon such Warrant exercise has been registered, qualified or deemed to be exempt from registration or qualification
under the securities laws of the state of residence of the Registered Holder of the Warrants, except pursuant to Section 7.4.
In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a Warrant, the holder
of such Warrant shall not be entitled to exercise such Warrant and such Warrant may have no value and expire worthless, in which
case the purchaser of a Unit containing such Public Warrants shall have paid the full purchase price for the Unit solely for the
shares of Common Stock underlying such Unit. Subject to Section 4.6 of this Agreement, a Registered Holder of Warrants
may exercise its Warrants only for a whole number of shares of Common Stock. In no event will the Company be required to net cash
settle the Warrant exercise. The Company may require holders of Public Warrants to settle the Warrant on a “cashless
basis” pursuant to subsection 3.3.1(b) and Section 7.4. If, by reason of any exercise of Warrants on a
 “cashless basis”, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a
fractional interest in a share of Common Stock, the Company shall round down to the nearest whole number, the number of shares of
Common Stock to be issued to such holder.


 






     


     


    

 


3.3.3          
Valid Issuance. All shares of Common Stock issued upon the proper exercise of a Warrant in conformity with this Agreement
shall be validly issued, fully paid and non-assessable.


 


3.3.4          
Date of Issuance. Each person in whose name any book-entry position or certificate, as applicable, for shares of Common
Stock is issued shall for all purposes be deemed to have become the holder of record of such shares of Common Stock on the date on which
the Warrant, or book-entry position representing such Warrant, was surrendered and payment of the Warrant Price was made, irrespective
of the date of delivery of such certificate in the case of a certificated Warrant, except that, if the date of such surrender and payment
is a date when the share transfer books of the Company or book-entry system of the Warrant Agent are closed, such person shall be deemed
to have become the holder of such shares of Common Stock at the close of business on the next succeeding date on which the share transfer
books or book-entry system are open.


 


3.3.5          
Maximum Percentage. A holder of a Warrant may notify the Company in writing in the event it elects to be subject to the
provisions contained in this subsection 3.3.5; however, no holder of a Warrant shall be subject to this subsection 3.3.5
unless he, she or it makes such election. If the election is made by a holder, the Warrant Agent shall not effect the exercise of the
holder’s Warrant, and such holder shall not have the right to exercise such Warrant, to the extent that after giving effect to such
exercise, such person (together with such person’s affiliates), to the Warrant Agent’s actual knowledge, would beneficially
own in excess of 4.9% or 9.8% (or such other amount as a holder may specify) (the “Maximum Percentage”)
of the shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the
aggregate number of shares of Common Stock beneficially owned by such person and its affiliates shall include the number of shares of
Common Stock issuable upon exercise of the Warrant with respect to which the determination of such sentence is being made, but shall exclude
shares of Common Stock that would be issuable upon (x) exercise of the remaining, unexercised portion of the Warrant beneficially
owned by such person and its affiliates and (y) exercise or conversion of the unexercised or unconverted portion of any other securities
of the Company beneficially owned by such person and its affiliates (including, without limitation, any convertible notes or convertible
preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as
set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d)
of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For purposes of the Warrant, in
determining the number of outstanding shares of Common Stock, the holder may rely on the number of outstanding shares of Common Stock
as reflected in (1) the Company’s most recent annual report on Form 10-K, quarterly report on Form 10-Q, current
report on Form 8-K or other public filing with the Commission as the case may be, (2) a more recent public announcement by the
Company or (3) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding.
For any reason at any time, upon the written request of the holder of the Warrant, the Company shall, within two (2) Business Days,
confirm orally and in writing to such holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding
shares of Common Stock shall be determined after giving effect to the conversion or exercise of equity securities of the Company by the
holder and its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. By written notice
to the Company, the holder of a Warrant may from time to time increase or decrease the Maximum Percentage applicable to such holder to
any other percentage specified in such notice; provided, however, that any such increase shall not be effective until the
sixty-first (61st) day after such notice is delivered to the Company.


 


4.                  
Adjustments.


 


4.1               
Stock Dividends.


 


4.1.1           Split-Ups.
If after the date hereof, and subject to the provisions of Section 4.6 below, the number of outstanding shares of Common
Stock is increased by a stock dividend payable in shares of Common Stock, or by a split-up of shares of Common Stock or other
similar event, then, on the effective date of such stock dividend, split-up or similar event, the number of shares of Common Stock
issuable on exercise of each Warrant shall be increased in proportion to such increase in the outstanding shares of Common Stock. A
rights offering to holders of the Common Stock entitling holders to purchase shares of Common Stock at a price less than the
 “Fair Market Value” (as defined below) shall be deemed a stock dividend of a number of shares of Common Stock equal to
the product of (i) the number of shares of Common Stock actually sold in such rights offering (or issuable under any other
equity securities sold in such rights offering that are convertible into or exercisable for the Common Stock) and (ii) one
(1) minus the quotient of (x) the price per share of Common Stock paid in such rights offering divided by (y) the
Fair Market Value. For purposes of this subsection 4.1.1, (i) if the rights offering is for securities convertible
into or exercisable for Common Stock, in determining the price payable for Common Stock, there shall be taken into account any
consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) “Fair
Market Value” means the volume weighted average price of the Common Stock as reported during the ten (10) trading day
period ending on the trading day prior to the first date on which the shares of Common Stock trade on the applicable exchange or in
the applicable market, regular way, without the right to receive such rights.


 






     


     


    

 


4.1.2          
Extraordinary Dividends. If the Company, at any time while the Warrants are outstanding and unexpired, shall pay a dividend
or make a distribution in cash, securities or other assets to the holders of the Common Stock on account of such shares of Common Stock
(or other shares of the Company’s capital stock into which the Warrants are convertible), other than (a) as described in subsection 4.1.1
above, (b) Ordinary Cash Dividends (as defined below), (c) to satisfy the redemption rights of the holders of the Common Stock
in connection with a proposed initial Business Combination, (d) as a result of the repurchase of shares of Common Stock by the Company
if a proposed Business Combination is presented to the stockholders of the Company for approval, (e) to satisfy the redemption rights
of the holders of Common Stock in connection with a stockholder vote to amend the Company’s amended and restated certificate of
incorporation to modify the substance or timing of the Company’s obligation to redeem 100% of the public shares of Common Stock
included in the Units sold in the Offering if the Company does not complete the Business Combination within the period set forth in the
Company’s amended and restated certificate of incorporation or (f) in connection with the redemption of public shares of Common
Stock upon the failure of the Company to complete its initial Business Combination and any subsequent distribution of its assets upon
its liquidation (any such non-excluded event being referred to herein as an “Extraordinary Dividend”), then
the Warrant Price shall be decreased, effective immediately after the effective date of such Extraordinary Dividend, by the amount of
cash and/or the fair market value (as determined by the Board, in good faith) of any securities or other assets paid on each share of
Common Stock in respect of such Extraordinary Dividend. For purposes of this subsection 4.1.2, “Ordinary Cash
Dividends” means any cash dividend or cash distribution which, when combined on a per share basis, with the per share amounts
of all other cash dividends and cash distributions paid on the Common Stock during the 365-day period ending on the date of declaration
of such dividend or distribution (as adjusted to appropriately reflect any of the events referred to in other subsections of this Section 4
and excluding cash dividends or cash distributions that resulted in an adjustment to the Warrant Price or to the number of shares of Common
Stock issuable on exercise of each Warrant) does not exceed $0.50 (being 5% of the offering price of the Units in the Offering).


 


4.2               
Aggregation of Shares. If after the date hereof, and subject to the provisions of Section 4.6 hereof, the number
of outstanding shares of Common Stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares
of Common Stock or other similar event, then, on the effective date of such consolidation, combination, reverse stock split, reclassification
or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be decreased in proportion to such decrease
in outstanding shares of Common Stock.


 


4.3               
Adjustments in Warrant Price.


 


4.3.1          
Whenever the number of shares of Common Stock purchasable upon the exercise of the Warrants is adjusted, as provided in subsection 4.1.1
or Section 4.2 above, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such Warrant Price immediately
prior to such adjustment by a fraction (x) the numerator of which shall be the number of shares of Common Stock purchasable upon
the exercise of the Warrants immediately prior to such adjustment, and (y) the denominator of which shall be the number of shares
of Common Stock so purchasable immediately thereafter.


 


4.3.2           If
(i) the Company issues additional shares of Class A common stock or equity-linked securities for capital raising purposes
in connection with the closing of the Company’s initial Business Combination at an issue price or effective issue price of
less than $9.20 per share of Common Stock (with such issue price or effective issue price to be determined in good faith by the
Board and, in the case of any such issuance to the Sponsors, without taking into account any shares of Class B common stock
held by our initial stockholders or their affiliates, as applicable, prior to such issuance) (the “Newly Issued
Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity
proceeds, and interest thereon, available for the funding of the initial Business Combination on the date of the consummation of the
initial Business Combination (net of redemptions), and (z) the volume weighted average trading price of the Common Stock during
the 20 trading day period starting on the trading day prior to the day on which the Company consummates the initial Business
Combination (such price, the “Market Value”) is below $9.20 per share of Class A common stock,
the Warrant Price shall be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly
Issued Price, and the last sales price of the Common Stock that triggers the Company’s right to redeem the Warrants pursuant
to Section 6.1 below shall be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value
and the Newly Issued Price.


 






     


     


    

 


4.4                Replacement
of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding shares of Common
Stock (other than a change under subsections 4.1.1 or 4.1.2 or Section 4.2 hereof or that solely
affects the par value of such shares of Common Stock), or in the case of any merger or consolidation of the Company with or into
another entity or conversion of the Company as another entity (other than a consolidation or merger in which the Company is the
continuing corporation and that does not result in any reclassification or reorganization of the outstanding shares of Common
Stock), or in the case of any sale or conveyance to another entity of the assets or other property of the Company as an entirety or
substantially as an entirety in connection with which the Company is dissolved, the holders of the Warrants shall thereafter have
the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu of the
shares of Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented
thereby, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such
reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the
holder of the Warrants would have received if such holder had exercised his, her or its Warrant(s) immediately prior to such event
(the “Alternative Issuance” ); provided, however, that in connection with the closing of any such
consolidation, merger, sale or conveyance, the successor or purchasing entity shall execute an amendment hereto with the Warrant
Agent providing for delivery of such Alternative Issuance; provided, further, that (i) if the holders of the
Common Stock were entitled to exercise a right of election as to the kind or amount of securities, cash or other assets receivable
upon such consolidation or merger, then the kind and amount of securities, cash or other assets constituting the Alternative
Issuance for which each Warrant shall become exercisable shall be deemed to be the weighted average of the kind and amount received
per share by the holders of the Common Stock in such consolidation or merger that affirmatively make such election, and (ii) if
a tender, exchange or redemption offer shall have been made to and accepted by the holders of the Common Stock (other than a tender,
exchange or redemption offer made by the Company in connection with redemption rights held by stockholders of the Company as
provided for in the Company’s amended and restated certificate of incorporation or as a result of the repurchase of shares of
Common Stock by the Company if a proposed initial Business Combination is presented to the stockholders of the Company for approval)
under circumstances in which, upon completion of such tender or exchange offer, the maker thereof, together with members of any
group (within the meaning of Rule 13d-5(b)(1) under the Exchange Act (or any successor rule)) of which such maker is a part,
and together with any affiliate or associate of such maker (within the meaning of Rule 12b-2 under the Exchange Act (or any
successor rule)) and any members of any such group of which any such affiliate or associate is a part, own beneficially (within the
meaning of Rule 13d-3 under the Exchange Act (or any successor rule)) more than 50% of the outstanding shares of Common
Stock, the holder of a Warrant shall be entitled to receive as the Alternative Issuance, the highest amount of cash, securities or
other property to which such holder would actually have been entitled as a stockholder if such Warrant holder had exercised the
Warrant prior to the expiration of such tender or exchange offer, accepted such offer and all of the Common Stock held by such
holder had been purchased pursuant to such tender or exchange offer, subject to adjustments (from and after the consummation of such
tender or exchange offer) as nearly equivalent as possible to the adjustments provided for in this Section 4; provided, further,
that if less than 70% of the consideration receivable by the holders of the Common Stock in the applicable event is payable in
the form of common stock in the successor entity that is listed for trading on a national securities exchange or is quoted in an
established over-the-counter market, or is to be so listed for trading or quoted immediately following such event, and if the
Registered Holder properly exercises the Warrant within thirty (30) days following the public disclosure of the consummation of
such applicable event by the Company pursuant to a Current Report on Form 8-K filed with the Commission, the Warrant Price
shall be reduced by an amount (in dollars) equal to the difference (but in no event less than zero) of (i) the Warrant Price in
effect prior to such reduction minus (ii) (A) the Per Share Consideration (as defined below) minus (B) the Black-Scholes
Warrant Value (as defined below). The “Black-Scholes Warrant Value” means the value of a Warrant
immediately prior to the consummation of the applicable event based on the Black-Scholes Warrant Model for a Capped American Call on
Bloomberg Financial Markets (“Bloomberg”). For purposes of calculating such amount,
(1) Section 6 of this Agreement shall be taken into account, (2) the price of each share of Common Stock shall
be the volume weighted average price of the Common Stock as reported during the ten (10) trading day period ending on the
trading day prior to the effective date of the applicable event, (3) the assumed volatility shall be the 90 day
volatility obtained from the HVT function on Bloomberg determined as of the trading day immediately prior to the day of the
announcement of the applicable event, and (4) the assumed risk-free interest rate shall correspond to the U.S. Treasury
rate for a period equal to the remaining term of the Warrant. “Per Share Consideration” means (i) if
the consideration paid to holders of the Common Stock consists exclusively of cash, the amount of such cash per share of Common
Stock, and (ii) in all other cases, the amount of cash per share of Common Stock, if any, plus the volume weighted average
price of the Common Stock as reported during the ten (10) trading day period ending on the trading day prior to the effective
date of the applicable event. If any reclassification or reorganization also results in a change in shares of Common Stock covered
by subsection 4.1.1, then such adjustment shall be made pursuant to subsection 4.1.1 or Sections 4.2, 4.3
and this Section 4.4. The provisions of this Section 4.4 shall similarly apply to successive
reclassifications, reorganizations, mergers or consolidations, sales or other transfers. In no event will the Warrant Price be
reduced to less than the par value per share issuable upon exercise of the Warrant.


 






     


     


    

 


4.5               
Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of shares of Common Stock issuable
upon exercise of a Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price
resulting from such adjustment and the increase or decrease, if any, in the number of shares of Common Stock purchasable at such price
upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation
is based. Upon the occurrence of any event specified in Sections 4.1, 4.2, 4.3 or 4.4, the Company
shall give written notice of the occurrence of such event to each holder of a Warrant, at the last address set forth for such holder in
the Warrant Register, of the record date or the effective date of the event. Failure to give such notice, or any defect therein, shall
not affect the legality or validity of such event.


 


4.6               
No Fractional Shares. Notwithstanding any provision contained in this Agreement to the contrary, the Company shall not issue
fractional shares of Common Stock upon the exercise of Warrants. If, by reason of any adjustment made pursuant to this Section 4,
the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share, the Company
shall, upon such exercise, round down to the nearest whole number the number of shares of Common Stock to be issued to such holder.


 


4.7               
Form of Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this Section 4,
and Warrants issued after such adjustment may state the same Warrant Price and the same number of shares of Common Stock as is stated
in the Warrants initially issued pursuant to this Agreement; provided, however, that the Company may at any time in its
sole discretion make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof,
and any Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be
in the form as so changed.


 


4.8               
Other Events. In case any event shall occur affecting the Company as to which none of the provisions of the preceding subsections
of this Section 4 are strictly applicable, but which would require an adjustment to the terms of the Warrants in order to
(i) avoid an adverse impact on the Warrants and (ii) effectuate the intent and purpose of this Section 4, then,
in each such case, the Company shall appoint a firm of independent public accountants, investment banking or other appraisal firm of recognized
national standing, which shall give its opinion as to whether or not any adjustment to the rights represented by the Warrants is necessary
to effectuate the intent and purpose of this Section 4 and, if they determine that an adjustment is necessary, the terms of
such adjustment, provided, however, that under no circumstances shall the Warrants be adjusted pursuant to this Section 4.8
as a result of any issuance of securities in connection with the Business Combination. The Company shall adjust the terms of the Warrants
in a manner that is consistent with any adjustment recommended in such opinion.


 









     


     


    

 


4.9               
 No Adjustment. For the avoidance of doubt, no adjustment shall be made to the terms of the Warrants solely as a result
of an adjustment to the conversion ratio of the Company’s Class B common stock (the “Class B Common Stock”)
into shares of Common Stock or the conversion of the shares of Class B Common Stock into shares of Common Stock, in each case, pursuant
to the Company’s amended and restated certificate of incorporation, as amended from time to time.


 


5.                  
Transfer and Exchange of Warrants.


 


5.1               
Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant upon
the Warrant Register, upon surrender of such Warrant for transfer, in the case of certificated Warrants, properly endorsed with signatures
properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new Warrant representing an equal
aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. In the case of certificated
Warrants, the Warrants so cancelled shall be delivered by the Warrant Agent to the Company from time to time upon request.


 


5.2               
Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for
exchange or transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered
Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided, however, that except
as otherwise provided herein or in any Book-Entry Warrant Certificate or Definitive Warrant Certificate, each Book-Entry Warrant Certificate
and Definitive Warrant Certificate may be transferred only in whole and only to the Depositary, to another nominee of the Depositary,
to a successor depository, or to a nominee of a successor depository; provided further, however, that in the event that
a Warrant surrendered for transfer bears a restrictive legend (as in the case of the Private Placement Warrants and the Working Capital
Warrants), the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange thereof until the Warrant Agent has received
an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants must also bear a
restrictive legend.


 


5.3               
Fractional Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which shall
result in the issuance of a warrant certificate or book-entry position for a fraction of a warrant, except as part of the Units.


 


5.4               
Service Charges. No service charge shall be made for any exchange or registration of transfer of Warrants.


 


5.5               
Warrant Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance
with the terms of this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the
Company, whenever required by the Warrant Agent, shall supply the Warrant Agent with Warrants duly executed on behalf of the Company for
such purpose.


 


5.6               
Transfer of Warrants. Prior to the Detachment Date, the Public Warrants may be transferred or exchanged only together with
the Unit in which such Warrant is included, and only for the purpose of effecting, or in conjunction with, a transfer or exchange of such
Unit. Furthermore, each transfer of a Unit on the register relating to such Units shall operate also to transfer the Warrants included
in such Unit. Notwithstanding the foregoing, the provisions of this Section 5.6 shall have no effect on any transfer of Warrants
on and after the Detachment Date.


 


6.                  
Redemption.


 


6.1                Redemption.
Subject to Section 6.5 hereof, not less than all of the outstanding Warrants may be redeemed, at the option of the
Company, at any time while they are exercisable and prior to their expiration, at the office of the Warrant Agent, upon notice to
the Registered Holders of the Warrants, as described in Section 6.3 below, at the price of $0.01 per Warrant (the “Redemption
Price”), provided that the last sales price of the Common Stock reported has been at least $18.00 per share (the
 “Redemption Trigger Price”; subject to adjustment in compliance with Section 4 hereof), on
each of twenty (20) trading days within the thirty (30) trading-day period ending on the third trading day prior to the
date on which notice of the redemption is given and provided that there is an effective registration statement covering the shares
of Common Stock issuable upon exercise of the Warrants, and a current prospectus relating thereto, available throughout
the 30-day Redemption Period (as defined in Section 6.3 below) or the Company has elected to require the exercise
of the Warrants on a “cashless basis” pursuant to subsection 3.3.1; provided, however, that if
and when the Public Warrants become redeemable by the Company, the Company may not exercise such redemption right if the issuance of
shares of Common Stock upon exercise of the Public Warrants is not exempt from registration or qualification under applicable state
blue sky laws or the Company is unable to effect such registration or qualification.


 






     


     


    

 


6.2               
Redemption of Warrants for $0.10 or for Ordinary Shares. Subject to Section 6.5 hereof, not less than all of
the outstanding Warrants may be redeemed, at the option of the Company, at any time during the Exercise Period, at the office of the Warrant
Agent, upon notice to the Registered Holders of the Warrants, as described in Section 6.3 below, at a Redemption Price of
$0.10 per Warrant, provided that (i) the closing price of the Common Stock for any 20 trading days within a 30 trading-day
period commencing once the Warrants become exercisable as provided in Section 3.1 and ending on the third trading day prior
to the date on which the Company sends a notice of redemption to the Registered Holders (the “Reference Value”)
equals or exceeds $10.00 per share (subject to adjustment in compliance with Section 4 hereof) and (ii) if the Reference
Value is less than $18.00 per share (subject to adjustment in compliance with Section 4 hereof), the Private Placement
Warrants are also concurrently called for redemption on the same terms as the outstanding Public Warrants. During the 30-day Redemption
Period in connection with a redemption pursuant to this Section 6.2, Registered Holders of the Warrants may elect to exercise
their Warrants on a “cashless basis” pursuant to subsection 3.3.1 and receive a number of Ordinary Shares determined
by reference to the table below, based on the Redemption Date (calculated for purposes of the table as the period to expiration of the
Warrants) and the “Redemption Fair Market Value” (as such term is defined in this Section 6.2) (a “Make-Whole
Exercise”). Solely for purposes of this Section 6.2, the “Redemption Fair Market Value”
shall mean the volume weighted average price of the Ordinary Shares for the ten (10) trading days immediately following the date
on which notice of redemption pursuant to this Section 6.2 is sent to the Registered Holders. In connection with any redemption
pursuant to this Section 6.2, the Company shall provide the Registered Holders with the Redemption Fair Market Value no later
than one (1) Business Day after the ten (10) trading day period described above ends.

The exact Fair Market
Value and Redemption Date may not be set forth in the table above, in which case, if the Fair Market Value is between two values in
the table or the Redemption Date is between two Redemption Dates in the table, the number of shares of Common Stock to be issued for
each Warrant exercised will be determined by a straight-line interpolation between the number of shares set forth for the higher and
lower Fair Market Values and the earlier and later Redemption Dates, as applicable, based on a 365 or 366-day year, as
applicable. For example, if the volume weighted average price of the Common Stock during the 10 trading days immediately
following the date on which the notice of redemption is sent to the holders of the Warrants is $11.00 per share, and at such
time there are 57 months until the expiration of the warrants, holders may choose to, in connection with this redemption
feature, exercise their Warrants for 0.277 shares of Common Stock for each whole warrant.


 






     


     


    

 


6.3               
Date Fixed for, and Notice of, Redemption. In the event that the Company elects to redeem all of the Warrants, the Company
shall fix a date for the redemption (the “Redemption Date”). Notice of redemption shall be mailed by first class
mail, postage prepaid, by the Company not less than thirty (30) days prior to the Redemption Date (such period, the “30-day
Redemption Period”) to the Registered Holders of the Warrants to be redeemed at their last addresses as they shall appear
on the registration books. Any notice mailed in the manner herein provided shall be conclusively presumed to have been duly given whether
or not the Registered Holder received such notice.


 


6.4               
Exercise After Notice of Redemption. The Warrants may be exercised, for cash (or on a “cashless basis” in accordance
with subsection 3.3.1(b) of this Agreement) at any time after notice of redemption shall have been given by the Company pursuant
to Section 6.3 hereof and prior to the Redemption Date. In the event that the Company determines to require all holders of
Warrants to exercise their Warrants on a “cashless basis” pursuant to subsection 3.3.1, the notice of redemption
shall contain the information necessary to calculate the number of shares of Common Stock to be received upon exercise of the Warrants,
including the “Fair Market Value” (as such term is defined in subsection 3.3.1(b) hereof) in such case. On and
after the Redemption Date, the record holder of the Warrants shall have no further rights except to receive, upon surrender of the Warrants,
the Redemption Price.


 


6.5               
Exclusion of Private Placement Warrants and Working Capital Warrants. The Company agrees that the redemption rights provided
in this Section 6 shall not apply to the Private Placement Warrants or the Working Capital Warrants if at the time of the
redemption such Private Placement Warrants or the Working Capital Warrants continue to be held by the Company’s Sponsors or any
Permitted Transferees, as applicable. However, once such Private Placement Warrants or Working Capital Warrants are transferred (other
than to Permitted Transferees under Section 2.6), the Company may redeem the Private Placement Warrants and the Working Capital
Warrants pursuant to Section 6.1, provided that the criteria for redemption are met, including the opportunity of the holder
of such Private Placement Warrants or the Working Capital Warrants to exercise the Private Placement Warrants and the Working Capital
Warrants prior to redemption pursuant to Section 6.4. Private Placement Warrants and Working Capital Warrants that are transferred
to persons other than Permitted Transferees shall upon such transfer cease to be Private Placement Warrants or Working Capital Warrants
and shall become Public Warrants under this Agreement.


 


7.                  
Other Provisions Relating to Rights of Holders of Warrants.


 


7.1               
No Rights as Stockholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a stockholder
of the Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights
to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the election of directors of
the Company or any other matter.


 


7.2               
Lost, Stolen, Mutilated, or Destroyed Warrants. If any Warrant is lost, stolen, mutilated, or destroyed, the Company and
the Warrant Agent may on such terms as to indemnity or otherwise as they may in their discretion impose (which shall, in the case of a
mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination, tenor, and date as the Warrant so lost, stolen,
mutilated, or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the
allegedly lost, stolen, mutilated, or destroyed Warrant shall be at any time enforceable by anyone.


 


7.3               
Reservation of Common Stock. The Company shall at all times reserve and keep available a number of its authorized but unissued
shares of Common Stock that shall be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement.


 









     


     


    

 


7.4               
 Registration of Common Stock; Cashless Exercise at Company’s Option.


 


7.4.1          
Registration of the Common Stock. The Company agrees that as soon as practicable, but in no event later than fifteen (15) Business
Days after the closing of its initial Business Combination, it shall use its best efforts to file with the Commission a post-effective
amendment to the Registration Statement, or a new registration statement registering, under the Securities Act, the issuance of the shares
of Common Stock issuable upon exercise of the Warrants. The Company shall use its best efforts to cause the same to become effective and
to maintain the effectiveness of such post-effective amendment or registration statement, and a current prospectus relating thereto, until
the expiration of the Warrants in accordance with the provisions of this Agreement. If any such post-effective amendment or registration
statement has not been declared effective by the 60th Business Day following the closing of the Business Combination, holders of
the Warrants shall have the right, during the period beginning on the 61st Business Day after the closing of the Business Combination
and ending upon such post-effective amendment or registration statement being declared effective by the Commission, and during any other
period when the Company shall fail to have maintained an effective registration statement covering the shares of Common Stock issuable
upon exercise of the Warrants, to exercise such Warrants on a “cashless basis,” by exchanging the Warrants (in accordance
with Section 3(a)(9) of the Securities Act (or any successor rule) or another exemption) for that number of shares of Common Stock
equal to the quotient obtained by dividing (x) the product of the number of shares of Common Stock underlying the Warrants, multiplied
by the difference between the Warrant Price and the “Fair Market Value” (as defined below) by (y) the Fair Market Value.
Solely for purposes of this subsection 7.4.1, “Fair Market Value” shall mean the volume weighted average price
of the Common Stock as reported during the ten (10) trading day period ending on the trading day prior to the date that notice of
exercise is received by the Warrant Agent from the holder of such Warrants or its securities broker or intermediary. The date that notice
of cashless exercise is received by the Warrant Agent shall be conclusively determined by the Warrant Agent. In connection with the “cashless
exercise” of a Public Warrant, the Company shall, upon request, provide the Warrant Agent with an opinion of counsel for the Company
(which shall be an outside law firm with securities law experience) stating that (i) the exercise of the Warrants on a cashless basis
in accordance with this subsection 7.4.1 is not required to be registered under the Securities Act and (ii) the shares
of Common Stock issued upon such exercise shall be freely tradable under United States federal securities laws by anyone who is not an
affiliate (as such term is defined in Rule 144 under the Securities Act (or any successor statute)) of the Company and, accordingly,
shall not be required to bear a restrictive legend. Except as provided in subsection 7.4.2, for the avoidance of any doubt,
unless and until all of the Warrants have been exercised or have expired, the Company shall continue to be obligated to comply with its
registration obligations under the first three sentences of this subsection 7.4.1.


 


7.4.2          
Cashless Exercise at Company’s Option. If the Common Stock is at the time of any exercise of a Warrant not listed
on a national securities exchange such that it satisfies the definition of a “covered security” under Section 18(b)(1)
of the Securities Act (or any successor statute), the Company may, at its option, (i) require holders of Public Warrants who exercise
Public Warrants to exercise such Public Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities
Act (or any successor statute) as described in subsection 7.4.1 and (ii) in the event the Company so elects, the Company
shall not be required to file or maintain in effect a registration statement for the registration, under the Securities Act, of the Common
Stock issuable upon exercise of the Warrants, notwithstanding anything in this Agreement to the contrary. If the Company does not elect
at the time of exercise to require a holder of Public Warrants who exercises Public Warrants to exercise such Public Warrants on a “cashless
basis,” it agrees to use its best efforts to register or qualify for sale the Common Stock issuable upon exercise of the Public
Warrant under the blue sky laws of the state of residence of the exercising Public Warrant holder to the extent an exemption is not available.


 


8.                  
Concerning the Warrant Agent and Other Matters.


 


8.1               
Payment of Taxes. The Company shall from time to time promptly pay all taxes and charges that may be imposed upon the Company
or the Warrant Agent in respect of the issuance or delivery of shares of Common Stock upon the exercise of the Warrants, but the Company
shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares of Common Stock.


 









     


     


    

 


8.2               
 Resignation, Consolidation, or Merger of Warrant Agent.


 


8.2.1          
Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties
and be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the
Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall appoint
in writing a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period
of thirty (30) days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the holder
of a Warrant (who shall, with such notice, submit his Warrant for inspection by the Company), then the holder of any Warrant may apply
to the Supreme Court of the State of New York for the County of New York for the appointment of a successor Warrant Agent at the Company’s
cost. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation organized and existing under
the laws of the State of New York, in good standing and having its principal office in the Borough of Manhattan, City and State of New
York, and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state
authority. After appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties,
and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further
act or deed; but if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the
expense of the Company, an instrument transferring to such successor Warrant Agent all the authority, powers, and rights of such predecessor
Warrant Agent hereunder; and upon request of any successor Warrant Agent the Company shall make, execute, acknowledge, and deliver any
and all instruments in writing for more fully and effectually vesting in and confirming to such successor Warrant Agent all such authority,
powers, rights, immunities, duties, and obligations.


 


8.2.2          
Notice of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice
thereof to the predecessor Warrant Agent and the Transfer Agent for the Common Stock not later than the effective date of any such appointment.


 


8.2.3          
Merger or Consolidation of Warrant Agent. Any entity into which the Warrant Agent may be merged or with which it may be
consolidated or any entity resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor
Warrant Agent under this Agreement without any further act.


 


8.3               
Fees and Expenses of Warrant Agent.


 


8.3.1          
Remuneration. The Company agrees to pay the Warrant Agent reasonable remuneration for its services as such Warrant Agent
hereunder and shall, pursuant to its obligations under this Agreement, reimburse the Warrant Agent upon demand for all expenditures that
the Warrant Agent may reasonably incur in the execution of its duties hereunder.


 


8.3.2          
Further Assurances. The Company agrees to perform, execute, acknowledge, and deliver or cause to be performed, executed,
acknowledged, and delivered all such further and other acts, instruments, and assurances as may reasonably be required by the Warrant
Agent for the carrying out or performing of the provisions of this Agreement.


 


8.4               
Liability of Warrant Agent.


 


8.4.1          
Reliance on Company Statement. Whenever in the performance of its duties under this Agreement, the Warrant Agent shall deem
it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder,
such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved
and established by a statement signed by the Chief Executive Officer, Chief Financial Officer, President, Executive Vice President, Vice
President, Secretary or Chairman of the Board of the Company and delivered to the Warrant Agent. The Warrant Agent may rely upon such
statement for any action taken or suffered in good faith by it pursuant to the provisions of this Agreement.


 









     


     


    

 


8.4.2          
 Indemnity. The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct or bad faith.
The Company agrees to indemnify the Warrant Agent and save it harmless against any and all liabilities, including judgments, costs and
reasonable counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement, except as a result of the
Warrant Agent’s gross negligence, willful misconduct or bad faith.


 


8.4.3          
Exclusions. The Warrant Agent shall have no responsibility with respect to the validity of this Agreement or with respect
to the validity or execution of any Warrant (except its countersignature thereof). The Warrant Agent shall not be responsible for any
breach by the Company of any covenant or condition contained in this Agreement or in any Warrant. The Warrant Agent shall not be responsible
to make any adjustments required under the provisions of Section 4 hereof or responsible for the manner, method, or amount
of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment; nor shall it by any act hereunder
be deemed to make any representation or warranty as to the authorization or reservation of any shares of Common Stock to be issued pursuant
to this Agreement or any Warrant or as to whether any shares of Common Stock shall, when issued, be valid and fully paid and non-assessable.


 


8.5               
Acceptance of Agency. The Warrant Agent hereby accepts the agency established by this Agreement and agrees to perform the
same upon the terms and conditions herein set forth and among other things, shall account promptly to the Company with respect to Warrants
exercised and concurrently account for, and pay to the Company, all monies received by the Warrant Agent for the purchase of shares of
Common Stock through the exercise of the Warrants.


 


8.6               
Waiver. The Warrant Agent has no right of set-off or any other right, title, interest or claim of any kind (“Claim”)
in, or to any distribution of, the Trust Account (as defined in that certain Investment Management Trust Agreement, dated as of the date
hereof, by and between the Company and the Warrant Agent as trustee thereunder) and hereby agrees not to seek recourse, reimbursement,
payment or satisfaction for any Claim against the Trust Account for any reason whatsoever. The Warrant Agent hereby waives any and all
Claims against the Trust Account and any and all rights to seek access to the Trust Account.


 


9.                  
Miscellaneous Provisions.


 


9.1               
Successors. All the covenants and provisions of this Agreement by or for the benefit of the Company or the Warrant Agent
shall bind and inure to the benefit of their respective successors and assigns.


 


9.2               
Notices. Any notice, statement or demand authorized by this Agreement to be given or made by the Warrant Agent or by the
holder of any Warrant to or on the Company shall be sufficiently given when so delivered if by hand or overnight delivery or if sent by

9.3               
Applicable Law and Exclusive Forum. The validity, interpretation, and performance of this Agreement and of the Warrants
shall be governed in all respects by the laws of the State of New York, without giving effect to conflicts of law principles that would
result in the application of the substantive laws of another jurisdiction. The Company hereby agrees that any action, proceeding or claim
against it arising out of or relating in any way to this Agreement shall be brought and enforced in the courts of the State of New York
or the United States District Court for the Southern District of New York, and irrevocably submits to such jurisdiction, which jurisdiction
shall be exclusive forum for any such action, proceeding or claim. The Company hereby waives any objection to such exclusive jurisdiction
and that such courts represent an inconvenient forum. Notwithstanding the foregoing, the provisions of this paragraph will not apply to
suits brought to enforce any liability or duty created by the Exchange Act or any other claim for which the federal district courts of
the United States of America are the sole and exclusive forum.


 


Any person or entity purchasing
or otherwise acquiring any interest in the Warrants shall be deemed to have notice of and to have consented to the forum provisions in
this Section 9.3. If any action, the subject matter of which is within the scope the forum provisions above, is filed in a
court other than a court located within the State of New York or the United States District Court for the Southern District of New York
(a “foreign action”) in the name of any warrant holder, such warrant holder shall be deemed to have consented
to: (x) the personal jurisdiction of the state and federal courts located within the State of New York or the United States District
Court for the Southern District of New York in connection with any action brought in any such court to enforce the forum provisions (an
 “enforcement action”), and (y) having service of process made upon such warrant holder in any such enforcement
action by service upon such warrant holder’s counsel in the foreign action as agent for such warrant holder.


 


9.4               
Persons Having Rights under this Agreement. Nothing in this Agreement shall be construed to confer upon, or give to, any
person or corporation other than the parties hereto and the Registered Holders of the Warrants and, for purposes of Sections 7.4,
9.4 and 9.8, the Representative, any right, remedy, or claim under or by reason of this Agreement or of any covenant,
condition, stipulation, promise, or agreement hereof. All covenants, conditions, stipulations, promises, and agreements contained in this
Agreement shall be for the sole and exclusive benefit of the parties hereto and, for purposes of Sections 7.4, 9.4
and 9.8, the Representative, and their successors and assigns and of the Registered Holders of the Warrants.


 


9.5               
Examination of the Warrant Agreement. A copy of this Agreement shall be available at all reasonable times at the office
of the Warrant Agent in the Borough of Manhattan, City and State of New York, for inspection by the Registered Holder of any Warrant.
The Warrant Agent may require any such holder to submit such holder’s Warrant for inspection by the Warrant Agent.


 


9.6               
Counterparts. This Agreement may be executed in any number of original or facsimile counterparts and each of such counterparts
shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.


 


9.7               
Effect of Headings. The section headings herein are for convenience only and are not part of this Agreement and shall not
affect the interpretation thereof.


 


9.8                Amendments.
This Agreement may be amended by the parties hereto without the consent of any Registered Holder (i) for the purpose of curing
any ambiguity, or correcting any mistake, including to conform the provisions of this Agreement to the description of the terms of
the Warrants and this Agreement in the Registration Statement or curing, correcting or supplementing any defective provision
contained herein or adding or changing any other provisions with respect to matters or questions arising under this Agreement as the
parties may deem necessary or desirable and that the parties deem shall not adversely affect the interest of the Registered Holders,
(ii) making any modifications or amendments that are necessary in the good faith determination of the Board (taking into
account then existing market precedents) to allow for the Warrants to be classified as equity in the Company’s financial
statements, provided that this clause (ii) shall not allow any modification or amendment to this Agreement that would adversely
affect the rights of the Registered Holders, including by increasing the Warrant Price or shortening the Exercise Period, which
shall require the vote or consent as provided in the next sentence, and (iii) to provide for the delivery of Alternative
Issuance pursuant to Section 4.4. All other modifications or amendments, including any amendment to increase the Warrant
Price or shorten the Exercise Period, shall require the vote or written consent of the Registered Holders of a majority of the then
outstanding Public Warrants. Any amendment solely to the Private Placement Warrants or the Working Capital Warrants shall require
the vote or written consent of a majority of the holders of the then outstanding Private Placement Warrants or the Working Capital
Warrants, as applicable. Notwithstanding the foregoing, the Company may lower the Warrant Price or extend the duration of the
Exercise Period pursuant to Sections 3.1 and 3.2, respectively, without the consent of the Registered
Holders.


 






     


     


    

 


9.9               
Severability. This Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision
hereof shall not affect the validity or enforceability of this Agreement or of any other term or provision hereof. Furthermore, in lieu
of any such invalid or unenforceable term or provision, the parties hereto intend that there shall be added as a part of this Agreement
a provision as similar in terms to such invalid or unenforceable provision as may be possible and be valid and enforceable.

Warrant Certificate


 


This Warrant Certificate
certifies that, or registered assigns, is the registered holder of warrant(s) evidenced hereby (the “Warrants”
and each, a “Warrant”) to purchase shares of Class A common stock, $0.0001 par value per share (“Common
Stock”), of Seaport Calibre Materials Acquisition Corp., a Delaware corporation (the “Company”).
Each whole Warrant entitles the holder, upon exercise during the period set forth in the Warrant Agreement referred to below, to receive
from the Company that number of fully paid and non-assessable shares of Common Stock as set forth below, at the exercise price (the “Warrant
Price”) as determined pursuant to the Warrant Agreement, payable in lawful money (or through “cashless exercise”
as provided for in the Warrant Agreement) of the United States of America upon surrender of this Warrant Certificate and payment of the
Warrant Price at the office or agency of the Warrant Agent referred to below, subject to the conditions set forth herein and in the Warrant
Agreement. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant
Agreement.


 


Each whole Warrant is initially
exercisable for one fully paid and non-assessable share of Common Stock. No fractional shares will be issued upon exercise of any Warrant.
If, upon the exercise of Warrants, a holder would be entitled to receive a fractional interest in a share of Common Stock, the Company
will, upon exercise, round down to the nearest whole number the number of shares of Common Stock to be issued to the Warrant holder. The
number of shares of Common Stock issuable upon exercise of the Warrants is subject to adjustment upon the occurrence of certain events
set forth in the Warrant Agreement.


 


The initial Warrant Price
per share of Common Stock for any Warrant is equal to $11.50 per whole share. The Warrant Price is subject to adjustment upon the
occurrence of certain events set forth in the Warrant Agreement.


 


Subject to the conditions
set forth in the Warrant Agreement, the Warrants may be exercised only during the Exercise Period and to the extent not exercised by the
end of such Exercise Period, such Warrants shall become void.


 


Reference is hereby made to
the further provisions of this Warrant Certificate set forth on the reverse hereof and such further provisions shall for all purposes
have the same effect as though fully set forth at this place.


 


This Warrant Certificate shall
not be valid unless countersigned by the Warrant Agent, as such term is used in the Warrant Agreement.


 


This Warrant Certificate shall
be governed by and construed in accordance with the internal laws of the State of New York, without regard to conflicts of laws principles
thereof.

[Form of Warrant Certificate]

[Reverse]


 


The Warrants evidenced by
this Warrant Certificate are part of a duly authorized issue of Warrants entitling the holder on exercise to receive shares of Common
Stock and are issued or to be issued pursuant to a Warrant Agreement dated as of _____, 2021 (the “Warrant Agreement”),
duly executed and delivered by the Company to Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent
(the “Warrant Agent”), which Warrant Agreement is hereby incorporated by reference in and made a part of this
instrument and is hereby referred to for a description of the rights, limitation of rights, obligations, duties and immunities thereunder
of the Warrant Agent, the Company and the holders (the words “holders” or “holder”
meaning the Registered Holders or Registered Holder, respectively) of the Warrants. A copy of the Warrant Agreement may be obtained by
the holder hereof upon written request to the Company. Defined terms used in this Warrant Certificate but not defined herein shall have
the meanings given to them in the Warrant Agreement.


 


Warrants may be exercised
at any time during the Exercise Period set forth in the Warrant Agreement. The holder of Warrants evidenced by this Warrant Certificate
may exercise them by surrendering this Warrant Certificate, with the form of election to purchase set forth hereon properly completed
and executed, together with payment of the Warrant Price as specified in the Warrant Agreement (or through “cashless exercise”
as provided for in the Warrant Agreement) at the principal corporate trust office of the Warrant Agent. In the event that upon any exercise
of Warrants evidenced hereby the number of Warrants exercised shall be less than the total number of Warrants evidenced hereby, there
shall be issued to the holder hereof or his, her or its assignee, a new Warrant Certificate evidencing the number of Warrants not exercised.


 


Notwithstanding anything else
in this Warrant Certificate or the Warrant Agreement, no Warrant may be exercised unless at the time of exercise (i) a registration
statement covering the shares of Common Stock to be issued upon exercise is effective under the Securities Act and (ii) a prospectus
thereunder relating to the shares of Common Stock is current, except through “cashless exercise” as provided for in the Warrant
Agreement.


 


The Warrant Agreement provides
that upon the occurrence of certain events the number of shares of Common Stock issuable upon exercise of the Warrants set forth on the
face hereof may, subject to certain conditions, be adjusted. If, upon exercise of a Warrant, the holder thereof would be entitled to receive
a fractional interest in a share of Common Stock, the Company shall, upon exercise, round down to the nearest whole number of shares of
Common Stock to be issued to the holder of the Warrant.


 


Warrant Certificates, when
surrendered at the principal corporate trust office of the Warrant Agent by the Registered Holder thereof in person or by legal representative
or attorney duly authorized in writing, may be exchanged, in the manner and subject to the limitations provided in the Warrant Agreement,
but without payment of any service charge, for another Warrant Certificate or Warrant Certificates of like tenor evidencing in the aggregate
a like number of Warrants.


 


Upon due presentation for
registration of transfer of this Warrant Certificate at the office of the Warrant Agent a new Warrant Certificate or Warrant Certificates
of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant
Certificate, subject to the limitations provided in the Warrant Agreement, without charge except for any tax or other governmental charge
imposed in connection therewith.


 


The Company and the Warrant
Agent may deem and treat the Registered Holder(s) hereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation
of ownership or other writing hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the holder(s) hereof,
and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. Neither the
Warrants nor this Warrant Certificate entitles any holder hereof to any rights of a stockholder of the Company.


 









     


     


    

 


Election to Purchase

(To Be Executed Upon Exercise of Warrant)


 


The undersigned hereby irrevocably
elects to exercise the right, represented by this Warrant Certificate, to receive shares of Common Stock and herewith tenders payment
for such shares of Common Stock to the order of Seaport Calibre Materials Acquisition Corp. (the “Company”) in the
amount of $             in accordance with the terms hereof. The undersigned
requests that a certificate for such shares of Common Stock be registered in the name of                   ,
whose address is and that such shares of Common Stock be delivered to whose address is                   .
If said number of shares of Common Stock is less than all of the shares of Common Stock purchasable hereunder, the undersigned requests
that a new Warrant Certificate representing the remaining balance of such shares of Common Stock be registered in the name of                   ,
whose address is and that such Warrant Certificate be delivered to                   ,
whose address is                   .


 


In the event that the Warrant
has been called for redemption by the Company pursuant to Section 6 of the Warrant Agreement and the Company has required
cashless exercise pursuant to Section 6.4 of the Warrant Agreement, the number of shares of Common Stock that this Warrant
is exercisable for shall be determined in accordance with subsection 3.3.1(b) and Section 6.4 of the Warrant Agreement.


 


In the event that the Warrant
has been called for redemption by the Company pursuant to Section 6.2 of the Warrant Agreement and a holder thereof elects
