 HIGHLAND ACQUISITION CORPORATION 

CUSIP 429859 119                    

 WARRANT 
 THIS CERTIFIES THAT,
for value received  
 is the registered holder of a warrant or warrants (the “Warrant(s)”) to purchase one fully paid and
non-assessable share of Common Stock, par value $0.0001 per share (“Shares”), of Highland Acquisition Corporation, a Delaware corporation (the “Company”), expiring at 5:00 p.m., New York City time, on the five year anniversary
(the “Expiration Date”) of the completion by the Company of a merger, share exchange, asset acquisition, stock purchase, recapitalization, reorganization or other similar business combination with one or more businesses or entities (a
“Business Combination”). The Warrant entitles the holder thereof to purchase from the Company, commencing on the later of (i) 30 days after the Company’s completion of a Business Combination and (ii)
                    , 2017, such number of Shares of the Company at the price of $11.50 per share, upon surrender of this Warrant Certificate
and payment of the Warrant Price at the office or agency of the Warrant Agent, Continental Stock Transfer & Trust Company, but only subject to the conditions set forth herein and in the Warrant Agreement between the Company and Continental Stock
Transfer & Trust Company. In no event will the Company be required to net cash settle the warrant exercise. The Warrant Agreement provides that upon the occurrence of certain events the Warrant Price and the number of Warrant Shares purchasable
hereunder, set forth on the face hereof, may, subject to certain conditions, be adjusted. The term Warrant Price as used in this Warrant Certificate refers to the price per Share at which Shares may be purchased at the time the Warrant is exercised.

 No fraction of a Share will be issued upon any exercise of a Warrant. If the holder of a Warrant would be entitled to receive a fraction
of a Share upon any exercise of a Warrant, the Company shall, upon such exercise, round up to the nearest whole number the number of Shares to be issued to such holder. 

Upon any exercise of the Warrant for less than the total number of full Shares provided for herein, there shall be issued to the registered
holder hereof or the registered holder’s assignee a new Warrant Certificate covering the number of Shares for which the Warrant has not been exercised. 

Warrant Certificates, when surrendered at the office or agency of the Warrant Agent by the registered holder hereof in person or by 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 and
evidencing in the aggregate a like number of Warrants. 
 Upon due presentment for registration of transfer of the Warrant Certificate at the
office or agency 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 in exchange for this Warrant Certificate, subject to
the limitations provided in the Warrant Agreement, without charge except for any applicable tax or other governmental charge. 
 The Company
and the Warrant Agent may deem and treat the registered holder as the absolute owner 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 registered holder, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. 

This Warrant does not entitle the registered holder to any of the rights of a stockholder of the Company. 

The Company reserves the right to call the Warrant at any time prior to its exercise, with a notice of call in writing to the holders of record
of the Warrant, giving 30 days’ notice of such call at any time after the Warrant becomes exercisable if the last sale price of the Shares has been at least $18.00 per share on each of 20 trading days within any 30 trading day period ending on
the third business day prior to the date on which notice of such call is given, if, and only if, there is a current registration statement in effect with respect to the Shares underlying the Warrant. The call price of the Warrants is to be $0.01 per
Warrant. Any Warrant either not exercised or tendered back to the Company by the end of the date specified in the notice of call shall be canceled on the books of the Company and have no further value except for the $0.01 call price.

 Exhibit 4.4 

WARRANT AGREEMENT 
 THIS
WARRANT AGREEMENT (“Agreement”) dated as of [                ], 2016 is between Highland Acquisition Corporation, a Delaware corporation,
(“Company”), and Continental Stock Transfer & Trust Company, a New York corporation (“Warrant Agent”). 
 WHEREAS,
the Company has received a binding commitment from its sponsor to purchase an aggregate of 6,750,000 warrants, or additional amounts of warrants if the underwriters in the Public Offering (defined below) exercise their over-allotment option, up to
7,500,000 warrants if the underwriters’ over-allotment option is exercised in full (the “Founders’ Warrants”), pursuant to a Founder Warrants Purchase Agreement (the “Founder Warrants Purchase Agreement”); and 

WHEREAS, the Company is engaged in a public offering (“Public Offering”) of units, each unit comprised of one share of Common Stock
(as defined below) and one half of one Public Warrant (as defined below) (the “Units”) and, in connection therewith, has determined to issue and deliver up to 12,500,000 warrants, or up to 14,375,000 Public Warrants if the
underwriters’ over-allotment option is exercised in full (the “Public Warrants” and together with the Founders’ Warrants, the “Warrants”), to the public investors, each such whole Warrant evidencing the right of the
holder thereof to purchase one share of common stock of the Company, par value $0.0001 per share (“Common Stock”), for $11.50, subject to adjustment as described herein; and 

WHEREAS, the Company has filed with the Securities and Exchange Commission a Registration Statement on Form S-1, No. 333-211544
(“Registration Statement”) for the registration, under the Securities Act of 1933, as amended (“Act”), of, among other securities, the 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 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, 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 of Directors or Chief Executive Officer and Treasurer, Secretary or Assistant Secretary of the
Company and shall bear a facsimile of the Company’s seal. 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.
Uncertificated Warrants. Notwithstanding anything herein to the contrary, any Warrant, or portion thereof, may be issued as part of, and be represented by, a Unit, and any Warrant may be issued in uncertificated or book-entry form through the
Warrant Agent and/or the facilities of The Depository Trust Company (the “Depositary”) or other book-entry depositary system, in each case as determined by the Board of Directors of the Company or by an authorized committee thereof. Any
Warrant so issued shall have the same terms, force and effect as a certificated Warrant that has been duly countersigned by the Warrant Agent in accordance with the terms of this Agreement. 

2.3. Effect of Countersignature. Except with respect to uncertificated Warrants as described above, unless and until countersigned
by the Warrant Agent pursuant to this Agreement, a Warrant shall be invalid and of no effect and may not be exercised by the holder thereof. 

  
 2 

 2.4. Registration. 

2.4.1. Warrant Register. The Warrant Agent shall maintain books (“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. 
 2.4.2. 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 then registered in 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. 
 2.5. Detachability of
Warrants. The securities comprising the Units will not be separately transferable until the 52nd day following the date of the prospectus or, if such 52nd day is not on a day, other than 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 with the consent of Ladenburg Thalmann & Co. Inc. (“Ladenburg”), but in no
event will Ladenburg allow separate trading of the securities comprising the Units until (i) the Company has filed a Current Report on Form 8-K which includes an audited balance sheet reflecting the receipt by the Company of the gross proceeds of
the Public Offering including the proceeds received by the Company from the exercise of the underwriters’ over-allotment option in the Public Offering, if the over-allotment option is exercised prior to the filing of the Form 8-K, and (ii) the
Company has issued a press release and has filed a Current Report on Form 8-K announcing when such separate trading shall begin (the “Detachment Date”). 

  
 3 

 2.6. Founders’ Warrant Attributes. The Founders’ Warrants will be issued in the
same form as the Public Warrants but they (i) will not be redeemable by the Company and (ii) may be exercised for cash or on a cashless basis at the holder’s option, in either case as long as the Founders’ Warrants are held by the initial
purchaser or its affiliates and permitted transferees (as prescribed in Section 5.6 hereof). Once a Founders’ Warrant is transferred to a holder other than an affiliate or permitted transferee, it shall be treated as a Public Warrant hereunder
for all purposes. 
 3. Terms and Exercise of Warrants 

3.1. Warrant Price. Each whole Warrant shall, when countersigned by the Warrant Agent, 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 refers to the price per share at which the 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 twenty (20) days prior written notice of such reduction to
registered holders of the Warrants and, provided further that any such reduction shall be applied consistently to all of the Warrants. 

3.2. Duration of Warrants. A Warrant may be exercised only during the period (“Exercise Period”) commencing on the later of
30 days after the consummation by the Company of a merger, share exchange, asset acquisition, stock purchase, recapitalization, reorganization or other similar business combination with one or more businesses or entities (“Business
Combination”) (as described more fully in the Registration Statement) or 12 months from 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 from the consummation of a
Business Combination and (ii) the Redemption Date as provided in Section 6.2 of this Agreement (“Expiration Date”). The period of time from the date the Warrants will first become exercisable until the expiration of the Warrants shall
hereafter be referred to as the “Exercise Period.” 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 Agreement shall cease at the close of business on the Expiration Date. The Company 

  
 4 

 
in its sole discretion may extend the duration of the Warrants by delaying the Expiration Date; provided, however, that the Company will provide at least twenty (20) days prior written notice of
any such extension to registered holders and, provided further that any such extension shall be applied consistently to all of the Warrants. 

3.3. Exercise of Warrants. 

3.3.1. Payment. Subject to the provisions of the Warrant and this Agreement, a Warrant, when countersigned by the Warrant
Agent, 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, in the Borough of Manhattan, City and State of New York, with the subscription form,
as set forth in the Warrant, duly executed, and by paying in full the Warrant Price for each 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, as follows:

 (a) by good certified check or good bank draft payable to the order of the Company (or as otherwise agreed to by the
Company); or 
 (b) in the event of redemption pursuant to Section 6 hereof in which the Company’s management has
elected to force all holders of 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” (defined below) by (y) the Fair Market Value. Solely for purposes of this Section 3.3.1(b), the “Fair
Market Value” shall mean the average reported last sale price of the Common Stock for the five (5) trading days ending on the third trading day prior to the date on which the notice of redemption is sent to holders of the Warrants pursuant to
Section 6 hereof; or 
 (c) with respect to any Founders’ Warrants, so long as such Founders’ Warrants are
held by the initial purchaser of the Founders’ Warrants or its permitted transferees, by surrendering such Founders’ 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 

  
 5 

 
underlying the Warrants, multiplied by the difference between the exercise price of the Warrants and the “Fair Market Value” by (y) the Fair Market Value; provided, however, that no
cashless exercise shall be permitted unless the Fair Market Value is equal to or higher than the exercise price. Solely for purposes of this Section 3.3.1(c), the “Fair Market Value” shall mean the average reported last sale price of the
Common Stock for the five (5) trading days ending on the third trading day prior to the date of exercise; or 
 (d) in
the event the registration statement required by Section 7.4 hereof is not effective and current within ninety (90) days after the closing of a Business Combination, by surrendering such 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 exercise price of the Warrants and the “Fair Market Value” by (y) the Fair Market
Value; provided, however, that no cashless exercise shall be permitted unless the Fair Market Value is equal to or higher than the exercise price. Solely for purposes of this Section 3.3.1(d), the “Fair Market Value” shall mean the average
reported last sale price of the Common Stock for the five (5) trading days ending on the day prior to the date of exercise. 
 3.3.2.
Issuance of Certificates. As soon as practicable after the exercise of any Warrant and the clearance of the funds in payment of the Warrant Price (if any), the Company shall issue to the registered holder of such Warrant a certificate or
certificates for the number of 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 countersigned Warrant
for the number of shares as to which such Warrant shall not have been exercised. Notwithstanding the foregoing, in no event will the Company be required to net cash settle the Warrant exercise. 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 under the securities laws of the state of residence
of the registered holder of the Warrants. In the event that the condition in the immediately preceding sentence is 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. Warrants may not be
exercised by, or securities issued to, any registered holder in any state in which such exercise would be unlawful. 

  
 6 

 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 nonassessable. 
 3.3.4. Date of
Issuance. Each person 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 share 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 share transfer books 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 9.8% (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”). 

  
 7 

 
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 Securities and Exchange Commission as the case may be, (2) a more recent public announcement by the
Company or (3) any other notice by the Company or Continental Stock Transfer & Trust Company 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; Split Ups. If after the date hereof, 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 outstanding shares of Common Stock. 
 4.2. Aggregation of
Shares. If after the date 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. 

  
 8 

 4.3 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 shares of Common Stock or other shares of the Company’s capital stock into which the Warrants are convertible (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; provided, however, that none of the following shall be deemed an Extraordinary Dividend for purposes of this
provision: (a) any adjustment described in subsection 4.1 above, (b) any cash dividends or cash distributions which, when combined on a per share basis with 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 does not exceed $0.50 (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) but only with respect to the amount of the aggregate cash dividends or cash distributions equal to or
less than $0.50, (c) any payment to satisfy the conversion rights of the holders of the shares of Common Stock in connection with a proposed initial Business Combination or (d) any payment in connection with the Company’s liquidation and the
distribution of its assets upon its failure to consummate a Business Combination. Solely for purposes of illustration, if the Company, at a time while the Warrants are outstanding and unexpired, pays a cash dividend of $0.35 and previously paid an
aggregate of $0.40 of cash dividends and cash distributions on the Common Stock during the 365-day period ending on the date of declaration of such $0.35 dividend, then the Warrant Price will be decreased, effectively immediately after the effective
date of such $0.35 dividend, by $0.25 (the absolute value of the difference between $0.75 (the aggregate amount of all cash dividends and cash distributions paid or made in such 365-day period, including such $0.35 dividend) and $0.50 (the greater
of (x) $0.50 and (y) the aggregate amount of all cash dividends and cash distributions paid or made in such 365-day period prior to such $0.35 dividend)). 

4.4 Adjustments in Exercise Price. 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 (x) the numerator of which shall be the number of
shares of Common 

  
 9 

 
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. 
 4.5. 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 Section 4.1, 4.2 or 4.3 hereof or that solely affects the par value of the 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 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 Warrant 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 Warrant holder
would have received if such Warrant holder had exercised his, her or its Warrant(s) immediately prior to such event; and if any reclassification also results in a change in the Common Stock covered by Section 4.1, 4.2 or 4.3, then such adjustment
shall be made pursuant to Sections 4.1, 4.2, 4.3, 4.4 and this Section 4.5. The provisions of this Section 4.5 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, 4.2, 4.3, 4.4 or 4.5, then, in any such event,
the Company shall give written notice to each Warrant holder, 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. 

  
 10 

 4.7. No Fractional Warrants or Shares. No fractional Warrants will be issued
hereunder. Additionally, notwithstanding any provision contained in this Agreement to the contrary, the Company shall not issue fractional shares upon 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 up to the nearest whole number of shares of Common Stock to be issued to the
Warrant holder. 
 4.8. 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 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. 
 4.9 Other Events. In case any event shall occur affecting the Company
as to which none of the provisions of 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. The Company shall adjust the
terms of the Warrants in a manner that is consistent with any adjustment recommended in such opinion. 
 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, 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 request. 

  
 11 

 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 in the event that a Warrant surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such Warrant and 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. 

5.3. 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. 
 5.4. 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, will supply
the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose. 
 5.6. Founders’ Warrants. The Warrant
Agent shall not register any transfer of Founders’ Warrants until 30 days after the consummation by the Company of an initial Business Combination, except for transfers (i) to the Company’s officers, directors, employees, consultants or
their affiliates, (ii) to a holder’s officers, directors, employees or members upon the holder’s liquidation, in each case if the holder is an entity, (iii) by bona fide gift to a member of the holder’s immediate family or to a trust,
the beneficiary of which is the holder or a member of the holder’s immediate family for estate planning purposes, (iv) by virtue of the laws of descent and distribution upon death, (v) pursuant to a qualified domestic relations order, (vi) to
the Company for no value for cancellation in connection with the 

  
 12 

 
consummation of a Business Combination or (vii) by private sales made at or prior to the consummation of a Business Combination at prices no greater than the price at which the Founders’
Warrants were originally purchased, in each case (except for clause (vi)) on the condition that prior to such registration for transfer, the Warrant Agent shall be presented with written documentation pursuant to which each transferee or the trustee
or legal guardian for such transferee agrees to be bound by the terms of the Founder Warrants Purchase Agreement and any other applicable agreement the transferor is bound by. 

5.7. Transfers prior to Detachment. 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 5.7 shall have no effect on any transfer of Warrants on or after the Detachment Date. 

6. Redemption. 
 6.1.
Redemption. Subject to Section 6.4 hereof, not less than all of the outstanding Public Warrants may be redeemed, at the option of the Company, at any time during the Exercise Period (so long as there is a current registration statement
in effect with respect to the shares of Common Stock underlying the Warrants), 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 equals or exceeds $18.00 per share (subject to adjustment in accordance with Section 4 hereof), on each of twenty (20) trading days within any thirty (30) trading day period ending on the third business day prior to
the date on which notice of redemption is given. 
 6.2. Date Fixed for, and Notice of, Redemption. In the event the Company shall
elect to redeem all of the Public 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 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. 

  
 13 

 6.3. Exercise After Notice of Redemption. The Public Warrants may be exercised, for cash
(or on a “cashless basis” in accordance with Section 3 of this 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. In the event the Company
determines to require all holders of Public Warrants to exercise their Warrants on a “cashless basis” pursuant to Section 3.3.1(b), the notice of redemption will 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” 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. 
 6.4 Exclusion of Founders’ Warrants. The Company agrees that the redemption rights provided
in this Section 6 shall not apply to the Founders’ Warrants if at the time of the redemption such Founders’ Warrants continue to be held by the initial purchaser or its permitted transferees. However, once such Founders’ Warrants are
transferred (other than to permitted transferees under Section 5.6), the Company may redeem the Founders’ Warrants in the same manner as the Public Warrants. 

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. 

  
 14 

 7.3. Reservation of Shares 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 Agreement. 

7.4. Registration of Shares of Common Stock. The Company agrees that as soon as practicable after the closing of its initial
Business Combination, but in no event later than fifteen (15) business days after such closing, it shall use its best efforts to file with the Securities and Exchange Commission a registration statement for the registration, under the Act, of the
shares of Common Stock issuable upon exercise of the Warrants, and it shall use its best efforts to take such action as is necessary to register or qualify for sale, in those states in which the Warrants were initially offered by the Company and in
those states where holders of Warrants then reside, the shares of Common Stock issuable upon exercise of the Warrants, to the extent an exemption is not available. The Company will use its best efforts to cause the same to become effective and
to maintain the effectiveness of such registration statement until the expiration of the Warrants in accordance with the provisions of this Agreement. If any such registration statement has not been declared effective by the 90th day following
the closing of the Business Combination, holders of the Warrants shall have the right, during the period beginning on the 91st day after the closing of the Business Combination and ending upon such registration statement being declared effective by
the Securities and Exchange 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” as determined in accordance with Section 3.3.1(d). The Company shall 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 Section 7.4 is not required to be registered under the Act and (ii) the shares of Common Stock issued upon such exercise will be freely tradable under U.S.
federal securities laws by anyone who is not an affiliate (as such term is defined in Rule 144 under the Act) of the Company and, accordingly, will not be required to bear a restrictive legend. For the avoidance of any doubt, unless and until
all of the Warrants have been exercised on a cashless basis, the Company shall continue to be obligated to comply with its registration obligations under the first three sentences of this Section 7.4. 

8. Concerning the Warrant Agent and Other Matters. 

  
 15 

 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 thirty (30) days after it has been notified in writing of such resignation or incapacity by the
Warrant Agent or by the holder of the 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 shares of Common Stock not later than the effective
date of any such appointment. 

  
 16 

 8.2.3. Merger or Consolidation of Warrant Agent. Any corporation into which the
Warrant Agent may be merged or with which it may be consolidated or any corporation 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 will 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 or Chairman of the Board of Directors 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 

  
 17 

 
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); nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Warrant; nor shall it 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 will, when issued,
be valid and fully paid and nonassessable. 
 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 Warrants. 
 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

9.3. Applicable Law. 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 

  
 19 

 
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. The Company hereby waives any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum. Any such process or summons to be served upon the Company may be served by
transmitting a copy thereof by registered or certified mail, return receipt requested, postage prepaid, addressed to it at the address set forth in Section 9.2 hereof. Such mailing shall be deemed personal service and shall be legal and binding
upon the Company in any action, proceeding or claim. 
 9.4. Persons Having Rights under this Agreement. Nothing in this
Agreement expressed and nothing that may be implied from any of the provisions hereof is intended, or 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
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 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 his Warrant for inspection by it. 

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

  
 20 

 
consent of any registered holder for the purpose of curing any ambiguity, or of 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. All other modifications or
amendments, including any amendment to increase the Warrant Price or shorten the Exercise Period, shall require the written consent or vote of the registered holders of a majority of the then outstanding Public Warrants. 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 Trust Account Waiver. The Warrant Agent acknowledges and agrees that it shall not make any claims or proceed against the trust
account established by the Company in connection with the Public Offering (as more fully described in the Registration Statement) (“Trust Account”), including by way of set-off, and shall not be entitled to any funds in the Trust Account
under any circumstance. In the event that the Warrant Agent has a claim against the Company under this Agreement, the Warrant Agent will pursue such claim solely against the Company and not against the property held in the Trust Account. 

9.10 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.
