 Exhibit 4.1 

Execution Version 
 WARRANT
AGREEMENT 
 This Warrant Agreement (“Warrant Agreement”) is made as of July 13, 2020, by and between PTK Acquisition Corp., a Delaware
corporation (the “Company”), and Continental Stock Transfer & Trust Company (the “Warrant Agent”). 
 WHEREAS,
the Company is engaged in a public offering (the “Public Offering”) of 10,000,000 units (the “Units”) of the Company (and up to 1,500,000 additional Units if the underwriters’ over-allotment option is exercised
in full), each Unit consisting of one share of common stock, par value $0.0001 per share (the “Common Stock”) and one warrant (the “Public Warrant” or “Public Warrants”), each Public Warrant
entitling its holder to purchase one half (1/2) of a share of Common Stock (the “Public Warrant Shares”) at an exercise price of $11.50 per whole share; 

WHEREAS, the Company has received a binding commitment from PTK Holdings LLC (the “Sponsor”) pursuant the Private Placement Warrant
Agreement, dated as of July 13, 2020 (“Subscription Agreement”) to purchase 6,800,000 warrants (the “Private Warrants”, and together with the Public Warrants, the “Warrants”), each Private Warrant entitling its
holder to purchase one half (1/2) of one share of Common Stock (“Private Warrant Shares”, and together with the Public Warrant Shares, the “Warrant Shares”) at an exercise price of $11.50 per whole share, dated of common stock;

 WHEREAS, the Company has filed with the Securities and Exchange Commission (the “SEC”) a Registration Statement on Form S-1, No. 333-239149 (“Registration Statement”), for the registration, under the Securities Act of 1933, as amended (the “Act”) of, among
other securities, the Public Warrants; and 
 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; and 
 WHEREAS, the Company
desires to provide for the form, terms and provisions of the Warrants, including 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 legally valid and binding obligations of the Company, and to authorize the execution and delivery of this Warrant 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 Warrant Agreement. 

2.    Warrants. 

2.1    Form of Warrant. Each Public Warrant shall be: (a) issued in registered form only, (b) in
substantially the form of Exhibit A hereto, the provisions of which are incorporated herein and (c) signed by, or bear the facsimile signature of, the Chairman of the Board, the Chief Executive Officer or the Chief Financial 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. Unless
and until countersigned by the Warrant Agent pursuant to this Warrant Agreement, a Warrant 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 the original issuance and transfers 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. 
 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 shall be registered upon the Warrant Register (“Registered
Holder”) as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of ownership or other writing on the 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. Each of the Common Stock and the Warrants comprising the Units will begin to
trade separately on (i) the 90th day after the effectiveness of the Registration Statement, or (ii) such earlier date as Chardan Capital Markets, LLC, as representative of the underwriters (the “Representative”), shall
determine is acceptable (such date, the “Detachment Date”). In no event will separate trading of the securities comprising the Units commence until the Company (i) files a Current Report on Form
8-K with the SEC including audited balance sheet reflecting our receipt of the gross proceeds of the Public Offering and (ii) issues a press release announcing when such separate trading will begin. 

2.5    Private Warrants. The Private Warrants will be issued substantially in the form of Exhibit A hereto,
except that they (i) will be exercisable either for cash or on a cashless basis at the holders option pursuant to Section 3.3 hereof and (ii) will not be redeemable by the Company, in either case as long as the Private Warrants are
held by the Sponsor or any of its permitted transferees (as prescribed in the Purchase Agreement). 
 3.    Terms and Exercise of
Warrants. 
 3.1    Warrant Price. Each Warrant shall, when countersigned by the Warrant Agent, entitle the
Registered Holder thereof, subject to the provisions of such Warrant and of this Warrant Agreement, to purchase from the Company the number of shares of Common Stock stated therein, at $11.50 per whole share, subject to the adjustments provided in
Section 4 hereof. The term “Warrant Price” as used in this Warrant Agreement refers to the price per whole share at which Common Stock may be purchased at the time such Warrant is exercised. The Public Warrants may only be
exercised for a whole number of Warrant Shares by a Registered Holder. No fractional shares will be issued. 

3.2    Duration of Warrants. A Warrant may be exercised only during the period (“Exercise Period”)
commencing on the later to occur of (i) the completion of the Company’s initial business combination and (ii) 12 months following the closing of the Public Offering, and terminating at 5:00 p.m., New York City time, on the earlier to occur
of (i) five years following the completion of the Company’s initial business combination with respect to the Public Warrants, and (ii) the date fixed for redemption of the Warrants as provided in Section 6 of this Warrant
Agreement (“Expiration Date”). Except with respect to the right to receive the Redemption Price (as set forth in Section 6 hereunder), each Warrant not exercised on or before the Expiration Date shall become void, and all
rights thereunder and all rights in respect thereof under this Warrant Agreement shall cease at the close of business on the Expiration Date. The Company may extend the duration of the Warrants by delaying the Expiration Date; provided, however,
that the Company will provide written notice of not less than 20 days to Registered Holders of such extension and that such extension shall be identical in duration among all of the then outstanding Warrants. 

3.3    Exercise of Warrants. 

3.3.1    Cash Exercise. Subject to the provisions of the Warrant and this Warrant Agreement, a Warrant, when
countersigned by the Company, may be exercised by the Registered Holder thereof by surrendering it at the office of the Warrant Agent, or at the office of its successor as Warrant Agent, currently being: 

Continental Stock Transfer & Trust Company 

1 State Street, 30th Floor 

New York, New York 10004 












 with the subscription form, as set forth in the Warrant, duly executed, and by paying in full, in lawful
money of the United States, by certified or bank cashier’s check payable to the order of the Warrant Agent or by wire transfer to the Warrant Agent’s JPMorgan bank account, the Warrant Price for each whole Warrant Share 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 Warrant Shares, and the issuance of the Warrant Shares (such exercise, a “Cash Exercise”).
A Cash Exercise in accordance with this Section 3.3.1 is available to the Registered Holder only during such times that there is an effective registration statement registering the Warrant Shares, with the prospectus contained therein being
available for the resale of the Warrant Shares. 
 3.3.2    Cashless Exercise. Subject to Section 2.4,
notwithstanding anything contained herein to the contrary, if there is no effective registration statement registering the Warrant Shares on any day the Registered Holder desires to exercise the Warrants and more than 90 days have passed since the
Company complete its initial business combination, the Registered Holder may exercise the Warrants in whole or in part in lieu of making a cash payment for whole numbers of Warrant Shares, by providing notice to the Chief Financial Officer of the
Company in a subscription form of its election to utilize cashless exercise, in which event the Company shall issue to the Holder the number of Warrant Shares determined as follows: 

X = Y [(A-B)/A] 

where: 
 X = the number of
Warrant Shares to be issued to the Holder. 
 Y = the number of Warrant Shares with respect to which this Warrant is being exercised. 

A = the fair market value of one share of Common Stock. 

B = the Warrant Price. 
 The Registered Holder
may not exercise any Warrants in the absence of a registration statement except pursuant to this Section 3.3.2. For purposes of this Section 3.3.2 and Section 4.1, the
fair market value of one share of Common Stock is defined as follows: 
 (i)    if the Company’s Common Stock is
listed and traded on the New York Stock Exchange, the NYSE America, the NASDAQ Global Select Market, the NASDAQ Global Market or the NASDAQ Capital Market (each, a “Trading Market”), the fair market value shall be deemed the average
of the closing price on such Trading Market for the 10 trading day ending on the third trading day immediately prior to the date the subscription form is submitted to the Company in connection with the exercise of the Warrant; or 

(ii)    if the Company’s Common Stock is not listed on a Trading Market, but is traded in the over-the-counter market, the fair market value shall be deemed to be the average of the bid price on such Trading Market for the 10 trading day ending on the third trading day
immediately prior to the date the subscription form is submitted in connection with the exercise of the Warrant; or 

(iii)    if there is no active public market for the Company’s Common Stock, the fair market value of the Common
Stock shall be determined in good faith by the Company’s board of directors. 
 3.3.3    Fractional Shares.
Notwithstanding any provision to the contrary contained in this Warrant Agreement, the Company shall not be required to issue any fraction of a Warrant Share in connection with the exercise of Warrants, and in any case where the Registered Holder
would be entitled under the terms of the Warrants to receive a fraction of a Warrant Share upon the exercise of such Registered Holder’s Warrants, issue or cause to be issued only 












 
the largest whole number of Warrant Shares issuable on such exercise (and such fraction of a Warrant Share will be disregarded); provided, that if more than one Warrant certificate is presented
for exercise at the same time by the same Registered Holder, the number of whole Warrant Shares which shall be issuable upon the exercise thereof shall be computed on the basis of the aggregate number of Warrant Shares issuable on exercise of all
such Warrants. 
 3.3.4    Issuance of Certificates. No later than three (3) business days following the
exercise of any Warrant and the clearance of the funds in payment of the Warrant Price pursuant to Section 3.3.1 or cashless exercise pursuant to Section 3.3.2, the Company shall issue, or cause to be issued, to the Registered Holder of
such Warrant a certificate or certificates representing (or at the option of the Registered Holder, deliver electronically through the facilities of the Depository Trust Corporation) 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 or surrendered in full, a new countersigned Warrant for the number of shares as to which such Warrant shall not
have been exercised or surrendered. Notwithstanding the foregoing, the Company shall not deliver, or cause to be delivered, any securities without applicable restrictive legend pursuant to the exercise of a Warrant unless (a) a registration
statement under the Act with respect to the Common Stock issuable upon exercise of such Warrants is effective and a current prospectus relating to the shares of Common Stock issuable upon exercise of the Warrants is available for delivery to the
Registered Holder of the Warrant or (b) in the opinion of counsel to the Company, the exercise of the Warrants is exempt from the registration requirements of the Act and such securities are qualified for sale or exempt from qualification under
applicable securities laws of the states or other jurisdictions in which the Registered Holder resides. Warrants may not be exercised by, or securities issued to, any Registered Holder in any state in which such exercise or issuance would be
unlawful. In addition, in no event will the Company be obligated to pay such Registered Holder any cash consideration upon exercise or otherwise “net cash settle” the Warrant. 

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

3.3.6    Date of Issuance. Each person or entity in whose name any such certificate for shares of Common Stock is
issued shall, for all purposes, be deemed to have become the holder of record of such shares on the date on which the Warrant was surrendered and payment of the Warrant Price was made, irrespective of the date of delivery of such certificate, except
that, if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the
stock transfer books are open. 
 4.    Adjustments. 

4.1    Stock Dividends, Splits. If, after the date hereof, and subject to the provisions of Section 4.5 below,
the number of outstanding shares of Common Stock is increased by a stock dividend payable in shares of Common Stock, or by a forward or reverse split of shares of Common Stock, or other similar event, then, on the effective date of such stock
dividend, split or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be increased or decreased in proportion to such increase or decrease in outstanding shares of Common Stock. A rights offering to all
holders of the shares of Common Stock entitling holders to purchase shares of Common Stock at a price less than the Fair Market Value 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 shares of Common Stock) multiplied by (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, if the rights offering is for securities convertible into or exercisable
for shares of Common Stock, in determining the price payable for the shares of 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. 

4.2    Aggregation of Shares. If, after the date hereof, and subject to the provisions of Section 4.6, the
number of outstanding shares of Common Stock is decreased by a consolidation, combination or reclassification of shares of Common Stock or other similar event, then, on the effective date of such consolidation, combination, 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    Extraordinary Dividends. If the Company, at any time while
the Warrants (or rights to purchase 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 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 above, (b) Ordinary Cash Dividends (as defined below), (c) to satisfy the conversion rights of the holders of the
Common Stock in connection with a proposed initial Business Combination, (d) as a result of the repurchase of Common Stock by the Company in connection with an initial Business Combination or as otherwise permitted by the Investment Management
Trust Agreement between the Company and the Warrant Agent dated of even date herewith or (e) in connection with the Company’s liquidation and the distribution of its assets upon its failure to consummate a Business Combination (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 the fair market value (as determined by the Company’s board of directors, 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 4.3, “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). 
 4.4    Adjustments in Exercise Price. 

4.4.1    Whenever the number of shares of Common Stock purchasable upon the exercise of the Warrants is adjusted, as
provided in Sections 4.1 and 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, (a) 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 (b) the denominator of which shall be the number of shares of Common Stock so purchasable immediately thereafter. 

4.4.2    If (x) the Company issues additional shares of Common Stock or equity-linked securities for capital raising
purposes in connection with the closing of the initial Business Combination at an issue price or effective issue price of less than $9.50 per share of Common Stock (with such issue price or effective issue price to be determined in good faith by the
Board), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for funding 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 Business Combination (such price, the “Market Value”) is below $9.50 per share,
the Warrant Price shall be adjusted (to the nearest cent) to be equal to 115% of the Market Value, 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 Market Value. 
 4.5    Replacement of Securities upon
Reorganization, etc. In case of any reclassification or reorganization of the outstanding shares of Common Stock (other than a change covered by Sections 4.1 or 4.2 hereof or one 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 corporation (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 corporation or 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 Registered Holders 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 Registered Holder would have received if such Registered Holder had exercised his, her or its Warrant(s) immediately prior to such event; and if any
reclassification also results in a change in shares of Common Stock covered by Sections 4.1 or 4.2, then such 












 
adjustment shall be made pursuant to Sections 4.1, 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. 
 4.6    Notices of Changes in Warrant.
Upon every adjustment of the Warrant Price or the number of shares 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 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 – 4.5 the Company shall give written notice to each Registered Holder, at the last address set forth for such Registered 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. 

4.7    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 as is stated in the Warrants initially issued pursuant to this Warrant Agreement. However, 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    Notice of Certain Transactions. In the event
that the Company shall (a) offer to holders of all its Common Stock rights to subscribe for or to purchase any securities convertible into shares of Common Stock or shares of stock of any class or any other securities, rights or options,
(b) issue any rights, options or warrants entitling all the holders of Common Stock to subscribe for shares of Common Stock, or (c) make a tender offer, redemption offer or exchange offer with respect to the Common Stock, the Company shall
send to the Registered Holders a notice of such action or offer. Such notice shall be mailed to the Registered Holders at their addresses as they appear in the Warrant Register, which shall specify the record date for the purposes of such dividend,
distribution or rights, or the date such issuance or event is to take place and the date of participation therein by the holders of Common Stock, if any such date is to be fixed, and shall briefly indicate the effect of such action on the Common
Stock and on the number and kind of any other shares of stock and on other property, if any, and the number of shares of Common Stock and other property, if any, issuable upon exercise of each Warrant and the Warrant Price after giving effect to any
adjustment pursuant to this Section 4 which would be required as a result of such action. Such notice shall be given as promptly as practicable after the Company has taken any such action. 

5.    Transfer and Exchange of Warrants. 

5.1    Transfer of Warrants. Prior to the Detachment Date, the 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. From and after the Detachment Date, this Section 5.1 will have no further force and effect. 

5.2    Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any
outstanding Warrant into the Warrant Register, upon surrender of such Warrant for transfer, 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. The Warrants so cancelled shall be delivered by the Warrant Agent to the Company from time to time upon the
Company’s request. 
 5.3    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, in the event a Warrant surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such Warrant and shall issue new Warrants in exchange therefor 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. 












 5.4    Fractional Warrants. The Warrant Agent shall not be
required to effect any registration of transfer or exchange which will result in the issuance of a warrant certificate for a fraction of a warrant. 

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

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

6.1    Redemption. Subject to the second sentence of this Section 6.1, all (and not less than all) of the
outstanding Warrants may be redeemed, in whole and not in part, at the option of the Company, at any time from and after the Warrants become exercisable, and prior to their expiration, at the office of the Warrant Agent, upon the notice referred to
in Section 6.2, at the price of $0.01 per Warrant (“Redemption Price”); provided that the last sales price of the Common Stock has been equal to or greater than $18.00 per share (subject to adjustment for splits, dividends,
recapitalizations and other similar events), for any twenty (20) trading days within a thirty (30) trading day period ending on the third business day prior to the date on which notice of redemption is given and provided further that there
is a current registration statement in effect with respect to the shares of Common Stock underlying the Warrants for each day in the aforementioned 30-day trading period and continuing each day thereafter
until the Redemption Date (defined below). For avoidance of doubt, if and when the warrants become redeemable by the Company under this Section, the Company may exercise its redemption right, even if it is unable to register or qualify the Warrant
Shares for sale under all applicable state securities laws. 
 6.2    Date Fixed for, and Notice of, Redemption.
In the event the Company shall elect 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 30 days prior to the date fixed for redemption to the Registered Holders of the Warrants to be redeemed at their last addresses as they shall appear on the Warrant Register. 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. 

6.3    Exercise After Notice of Redemption. The Warrants may be exercised in accordance with Section 3 of this
Warrant Agreement at any time after notice of redemption shall have been given by the Company pursuant to Section 6.2 hereof and prior to the Redemption Date; provided that the Company may require the Registered Holder who desires to exercise
the Warrant to elect cashless exercise as set forth under Section 3.3.2, and such Registered Holder must exercise the Warrants on a cashless basis if the Company so requires. On and after the Redemption Date, the Registered Holder of the
Warrants shall have no further rights except to receive, upon surrender of the Warrants, the Redemption Price. 

6.4    No Other Rights to Cash Payment. Except for a redemption in accordance with this Section 6, no
Registered Holder of any Warrant shall be entitled to any cash payment whatsoever from the Company in connection with the ownership, exercise or surrender of any Warrant under this Warrant Agreement. 

7.    Other Provisions Relating to Rights of Registered 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 terms 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 will be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Warrant Agreement. 

7.4    Registration of Common Stock. The Company agrees that as soon as practicable, but in no event later than
thirty (30) business days after the closing of a Business Combination, it shall use its best efforts to file with the SEC a registration statement for the registration under the Act of the shares of Common Stock issuable upon exercise of the
Warrants, and to cause the same to become effective and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the Warrants in accordance with the provisions of this
Agreement. In addition, the Company agrees to use its best efforts to register the shares of Common Stock issuable upon exercise of the Warrants under state blue sky laws, to the extent an exemption is not available. 

8.    Concerning the Warrant Agent and Other Matters. 

8.1    Payment of Taxes. The Company will, 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 Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares.

 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 30 days after it has been notified in writing of such resignation or
incapacity by the Warrant Agent or by the Registered Holder of the Warrant (who shall, with such notice, submit his, her or its Warrant for inspection by the Company), then the Registered 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. 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 be authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state
authorities. 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
