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,

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

provisions of which are incorporated herein and shall be signed by, or bear the facsimile signature of, the Chairman of the Board
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



    	 



    

 


2.2.        Effect
of Countersignature. 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.


 


2.3.        Registration.


 


2.3.1.          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.


 


2.3.2.          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

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 over-allotment option, if the over-allotment option is exercised on the date hereof,

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 Ordinary Shares stated therein, at the
price of $11.50 per whole 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 Warrant Agreement refers to the price per share at which Ordinary Shares
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 10 business days; provided, however, that the Company
shall provide at least 10 business days prior written notice of such reduction to registered holders of the Warrants; provided,
further, however, that any such reduction shall be applied consistently to all of the Warrants.


 




    	4



    	 



    

 


3.2.        Duration
of Warrants. A Warrant may be exercised only during the period (“Exercise Period”) commencing on the later of the
consummation by the Company of a merger, share exchange, asset acquisition, share 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) and ________, 2015 [one year from the date of this agreement], 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 (ii) the liquidation
of the Company, and (iii) the Redemption Date as provided in Section 6.2 of this Agreement (“Expiration Date”); provided,
however, that the exercise of any Warrant shall be subject to the satisfaction of any applicable conditions, as set forth in Section
7.4 below. 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 in its sole discretion may extend the duration
of the Warrants by delaying the Expiration Date; provided, however, that the Company will provide written notice to registered
holders of the Warrants of such extension of not less than 20 days.


 


3.3.        Exercise
of Warrants.


 


3.3.1.          Payment.
Subject to the provisions of the Warrant and this Warrant 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 full Ordinary Share 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)            in
lawful money of the United States, in good certified check or good bank draft payable to the order of the Warrant Agent;


 




    	5



    	 



    

 


(b)          in
the event of redemption pursuant to Section 6 hereof in which the Company’s management has elected to require all holders
of Warrants to exercise such Warrants on a “cashless basis,” by surrendering the Warrants for that number of Ordinary
Shares equal to the quotient obtained by dividing (x) the product of the number of Ordinary Shares 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 Ordinary Shares for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption
is sent to holders of Warrant pursuant to Section 6 hereof; or


 




    	6



    	 



    

 


(c)          in
the event the post-effective amendment or registration statement required by Section 7.4 hereof is not effective and current, then
during the period beginning on the 91st day after the closing of the Business Combination and ending upon the effectiveness
of such post-effective amendment or registration statement, and during any other period after such date of effectiveness when the
Company shall fail to have maintained an effective registration statement covering the Ordinary Shares issuable upon exercise of
the Warrants, by surrendering such Warrants for that number of Ordinary Shares equal to the quotient obtained by dividing (x) the
product of the number of Ordinary Shares 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 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 Ordinary Shares for the 10 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 full Ordinary Shares to which he 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, the Company shall not be obligated to issue Ordinary Shares
pursuant to the exercise of a Warrant unless at the time a holder seeks to exercise such Warrant, a prospectus relating to the
Ordinary Shares issuable upon exercise of such exercise is current and the Ordinary Shares have been registered or qualified or
deemed to be exempt under the securities laws of the state of residence of the holder of the Warrant. in no event will the Company
be required to net cash settle the Warrant exercise. Warrants may not be exercised by, or securities issued to, any registered
holder in any state in which such exercise would be unlawful.


 


3.3.3.          Valid
Issuance. All Ordinary Shares issued upon the proper exercise of a Warrant in conformity with this Agreement shall be validly
issued, fully paid and nonassessable.


 




    	7



    	 



    

 


3.3.4.          Date
of Issuance. Each person in whose name any such certificate for Ordinary Shares 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 Ordinary Shares outstanding immediately after
giving effect to such exercise.  For purposes of the foregoing sentence, the aggregate number of Ordinary Shares beneficially
owned by such person and its affiliates shall include the number of Ordinary Shares issuable upon exercise of the Warrant with
respect to which the determination of such sentence is being made, but shall exclude Ordinary Shares 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 shares or warrants) subject
to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence,
for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange
Act of 1934, as amended (the “Exchange Act”).  For purposes of the Warrant, in determining the number of
outstanding Ordinary Shares, the holder may rely on the number of outstanding Ordinary Shares as reflected in (1) the Company’s
most recent annual report on Form 10-K, quarterly report on Form 10-Q, current report on Form 8-K or other public filing with the
Commission as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or the
Transfer Agent setting forth the number of Ordinary Shares 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 Ordinary Shares then outstanding.  In any case, the number of outstanding Ordinary Shares 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 Ordinary Shares 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.        Share
Dividends - Split Ups. If after the date hereof, the number of outstanding Ordinary Shares is increased by a share dividend
payable in Ordinary Shares, or by a split up of the Ordinary Shares, or other similar event, then, on the effective date of such
share dividend, split up or similar event, the number of Ordinary Shares issuable on exercise of each Warrant shall be increased
in proportion to such increase in outstanding Ordinary Shares. A rights offering to all holders of the Ordinary Shares entitling
holders to purchase Ordinary Shares at a price less than the “Fair Market Value” (as defined below) shall be deemed
a share dividend of a number of Ordinary Shares equal to the product of (i) the number of Ordinary Shares 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 Ordinary Shares) multiplied by (ii) one (1) minus the quotient of (x) the price per Ordinary Share paid in such rights
offering divided by (y) the Fair Market Value. For purposes of this subsection 4.1, (i) if the rights offering is for securities
convertible into or exercisable for Ordinary Shares, in determining the price payable for the Ordinary Shares, there shall be taken
into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and
(ii) “Fair Market Value” means the volume weighted average price of the Ordinary Shares as reported during the ten
(10) trading day period ending on the trading day prior to the first date on which the Ordinary Shares trade on the applicable
exchange or in the applicable market, regular way, with the right to receive such rights.


 




    	9



    	 



    

 


4.2.        Aggregation
of Shares. If after the date hereof, the number of outstanding Ordinary Shares is decreased by a consolidation, combination,
reverse share split or reclassification of the Ordinary Shares or other similar event, then, on the effective date of such consolidation,
combination, reverse share split, reclassification or similar event, the number of Ordinary Shares issuable on exercise of each
Warrant shall be decreased in proportion to such decrease in outstanding Ordinary Shares.


 


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 Ordinary Shares
on account of such Ordinary Shares (or other shares of the Company’s share capital 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 Ordinary Shares in connection with a proposed initial Business Combination, (d) as a result of the
repurchase of Ordinary Shares 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 Ordinary
Share 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 Ordinary Shares 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 Ordinary
Shares issuable on exercise of each Warrant) does not exceed $0.50 (being 5% of the offering price of the Units in the Offering).


 




    	10



    	 



    

 


4.4         Adjustments
in Exercise Price. Whenever the number of Ordinary Shares purchasable upon the exercise of the Warrants is adjusted, as provided
in Section 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 Ordinary Shares purchasable upon the exercise
of the Warrants immediately prior to such adjustment, and (y) the denominator of which shall be the number of Ordinary Shares so
purchasable immediately thereafter.


 


4.5.        Replacement
of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding Ordinary Shares
(other than a change covered by Section 4.1 or 4.2 hereof or that solely affects the par value of such Ordinary Shares), 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
Ordinary Shares), 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 Ordinary Shares 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 Ordinary Shares covered by Section 4.1 or 4.2, then such adjustment
shall be made pursuant to Sections 4.1, 4.2, 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.


 




    	11



    	 



    

 


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.


 


4.7.        No
Fractional Shares. Notwithstanding any provision contained in this Warrant 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 or down to the nearest whole number the number of the Ordinary Shares 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; provided, however, that the Company may at any time in its sole discretion make any change in the form
of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued
or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed.


 




    	12



    	 



    

 


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 such firm determines 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.


 


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.


 




    	13



    	 



    

 


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.


 


6.            Redemption.


 


6.1.        Redemption.
Subject to Section 6.4 hereof, not less than all of the outstanding Warrants may be redeemed, at the option of the Company, at
any time while they are exercisable and prior to their expiration, at the office of the Warrant Agent, upon the notice referred
to in Section 6.2, at the price of $.01 per Warrant (“Redemption Price”), provided that the last sales price of the
Ordinary Shares has been at least $24.00 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 (“30-Day Trading 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 Ordinary Shares underlying the Warrants for each day in the 30-Day Trading Period and continuing
each day thereafter until the Redemption Date (defined below).


 




    	14



    	 



    

 


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 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.


 


6.3.        Exercise
After Notice of Redemption. The 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 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 Ordinary Shares 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 Certain Warrants. The Company understands that the redemption rights provided for by this Section 6 apply only to outstanding
Warrants. To the extent a person holds rights to purchase Warrants, such purchase rights shall not be extinguished by redemption.
However, once such purchase rights are exercised, the Company may redeem the Warrants issued upon such exercise provided that the
criteria for redemption is met. The provisions of this
Section 6.4 may not be modified, amended or deleted without the prior written consent of EBC.


 




    	15



    	 



    

 


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


 


7.1.        No
Rights as Shareholder. A Warrant does not entitle the registered holder thereof to any of the rights of a shareholder 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 shareholders in respect of the meetings of shareholders or the election of directors
of the Company or any other matter.


 


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


 


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

7.4.        Registration
of Ordinary Shares. The Company agrees that as soon as practicable, but in no event later than the closing of a Business Combination,
it shall use its best efforts to file with the SEC a post-effective amendment to the Registration Statement, or a new registration
statement, for the registration, under the Act, of the Ordinary Shares issuable upon exercise of the Warrants, and it shall use
its best efforts to take such action as is necessary to qualify for sale, in those states in which the Warrants were initially
offered by the Company, the Ordinary Shares issuable upon exercise of the Warrants. In either case, the Company will use its best
efforts 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 such securities under the blue sky laws of the states of residence of the exercising
warrant holders to the extent an exemption is not available. If any such post-effective amendment or registration statement has
not been declared effective by the 90-day anniversary 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 post-effective amendment or registration statement being declared effective by the SEC, and during any other period
after such date of effectiveness when the Company shall fail to have maintained an effective registration statement covering the
Ordinary Shares 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 issuance of Ordinary Shares upon 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
Ordinary Shares 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.
The provisions of this Section 7.4 may not be modified, amended or deleted without the prior written consent of EBC.

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 Ordinary Shares 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 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 Ordinary Shares not later than the effective date of any such appointment.


 


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 Warrant 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 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.


 




    	19



    	 



    

 


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


 


8.4.3.          Exclusions.
The Warrant Agent shall have no responsibility with respect to the validity of this Agreement or with respect to the validity or
execution of any Warrant (except its countersignature thereof); 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 Ordinary Shares to be issued pursuant to this Agreement or any Warrant
or as to whether any Ordinary Shares 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 moneys received by the Warrant Agent for the purchase of Ordinary Shares
through the exercise of Warrants.


 


8.6         Waiver.
The Warrant Agent hereby waives any right of set-off or any other right, title, interest or claim of any kind (“Claim”)
in, or to any distribution of, the Trust Account (as defined in that certain Investment Management Trust Agreement, dated as of
the date hereof, by and between the Company and the Warrant Agent as trustee thereunder) and hereby agrees not to seek recourse,
reimbursement, payment or satisfaction for any Claim against the Trust Account for any reason whatsoever.
