WHEREAS,
Parent, HL, and the Warrant Agent entered into that certain Novation Agreement (“Novation Agreement”), dated
on or about the date hereof, pursuant to which, in accordance with Section 9.1 of the Prior Agreement, Parent was substituted
for HL in the Prior Agreement and became obligated to perform all of the duties of HL under the Prior Agreement;

 

WHEREAS,
for the purpose of curing any ambiguity as to whether the Prior Agreement applies to the Warrants following the Closing, Parent
and the Warrant Agent desire to amend and restate the Prior Agreement pursuant to Section 9.8 of the Prior Agreement, to provide
that the same form and provisions applicable under the Prior Agreement apply to the Warrants;

 

WHEREAS,

the underwriters of HL’s initial public offering has consented to the amendments to sections 2.7, 6.4, 7.4, 9.4, and 9.8
of the Prior Agreement which remove all references to the “Representative” and “Representative Warrants”,
as required by the Prior Agreement; and

 

WHEREAS,
all acts and things have been done and performed which are necessary to make the Warrants, when executed on behalf of Parent and
countersigned by or on behalf of the Warrant Agent, as provided herein, the valid, binding, and legal obligations of Parent, 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. Parent hereby appoints the Warrant Agent to act as agent for Parent 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 held 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 Chief Financial Officer, Treasurer, Secretary or Assistant Secretary of Parent
and shall bear a facsimile of Parent’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 delivered, it
may be issued with the same effect as if he or she had not ceased to be such at the date of delivery.

 

2.2.
Uncertificated Warrants. Notwithstanding anything herein to the contrary, any Warrant may be held 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 Parent or by an authorized committee
thereof. Any Warrant so held 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.

 

2.4.
Registration.

 

2.4.1.
Warrant Register. The Warrant Agent shall maintain books (“Warrant Register”) for the registration of
original issuance, automatic adjustment by virtue of the Merger and the registration of transfer of the Warrants. Upon the initial
issuance or automatic adjustment of the Warrants, the Warrant Agent shall deliver 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 Parent.

  

    2

     

    

 

2.4.2.
Registered Holder. Prior to due presentment for registration of transfer of any Warrant, Parent 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 Parent or the Warrant Agent), for the purpose of any exercise thereof,
and for all other purposes, and neither Parent nor the Warrant Agent shall be affected by any notice to the contrary.

 

2.5.
Private Warrant Attributes. The Placement Warrants, Working Capital Warrants, Fusion Fuel Warrants and Contingent Consideration
Warrants (collectively, the “Private Warrants”) will be automatically adjusted or issued (as applicable) in
the same form as the IPO Warrants but they (i) will not be redeemable by Parent and (ii) may be exercised for cash or on a cashless
basis at the holder’s option in such manner as Parent’s management may specify, in either case as long as they are
held by the initial purchasers or their permitted transferees (as prescribed in Section 5.6 hereof). Once a Private Warrant is
transferred to a holder other than an affiliate or permitted transferee, it shall be treated as an IPO Warrant hereunder for all
purposes.

   

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 Agreement, to subscribe from Parent the number of Parent Class A Ordinary Shares
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 Parent Class A Ordinary Shares may be subscribed for at the time a Warrant is exercised. Parent 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 ten (10) Business
Days; provided, that Parent shall provide at least ten (10) 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 any time and from time to time beginning on the date hereof and terminating
at 5:00 p.m., New York City time on the earlier to occur of (i) five years from the date hereof and (ii) the Redemption Date as
provided in Section 6.2 of this Agreement, if applicable (“Expiration Date”). The period of time from the date
the Warrants will first become exercisable until the Expiration Date shall hereafter be referred to as the “Exercise
Period.” Except, as applicable, 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. Parent in its sole discretion
may extend the duration of the Warrants by delaying the Expiration Date; provided, however, that Parent will provide at least
twenty (20) days written notice prior to the then Expiration Date 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 Parent Class A 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)
by good certified check or wire payable to the Warrant Agent; or

 

(b)
in the event of redemption pursuant to Section 6 hereof in which Parent’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 Parent Class
A Ordinary Shares equal to the quotient obtained by dividing (x) the product of the number of Parent Class A 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, and by paying the nominal value (being US$0.0001 per share on the date of this Agreement) for each
Parent Class A Ordinary Share. Solely for purposes of this Section 3.3.1(b), the “Fair Market Value” shall
mean the average reported last sale price of Parent Class A Ordinary Shares 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 

 

    3

     

    

 

(c)
with respect to any Private Warrants, so long as such Private Warrants are held by the initial purchasers or their permitted transferees,
by surrendering such Private Warrants for that number of Parent Class A Ordinary Shares equal to the quotient obtained by dividing
(x) the product of the number of Parent Class A Ordinary Shares underlying such Private Warrants, multiplied by the difference
between the exercise price of such Private Warrants and the “Fair Market Value” (defined below) by (y) the
Fair Market Value, and by paying the nominal value (being US$0.0001 per share on the date of this Agreement) for each Parent Class
A Ordinary Share; 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 Parent Class A Ordinary Shares for the five (5) trading days ending on the trading day prior
to the date of exercise; or

 

(d)
in the event the registration statement required by Section 7.4 hereof is not then effective, by surrendering such Warrants for
that number of Parent Class A Ordinary Shares equal to the quotient obtained by dividing (x) the product of the number of Parent
Class A Ordinary Shares underlying the Warrants, multiplied by the difference between the exercise price of the Warrants and the
“Fair Market Value” (defined below) by (y) the Fair Market Value, and by paying the nominal value (being US$0.0001
per share on the date of this Agreement) for each Parent Class A Ordinary Share; 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 Parent Class A Ordinary Shares
for the five (5) trading days ending on the trading 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), and except with respect to uncertificated Warrants as described above in Section 2.2, Parent shall
issue to the registered holder of such Warrant a certificate or certificates for the number of Parent Class A Ordinary Shares
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 Parent be required to net cash settle the Warrant exercise.
No Warrant shall be exercisable for cash and Parent shall not be obligated to issue Parent Class A Ordinary Shares upon exercise
of a Warrant unless Parent Class A Ordinary Shares 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 for cash and such Warrant may have no value and expire worthless. 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 Parent Class A Ordinary Shares 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 Parent Class A 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 Parent 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.

 

    4

     

    

 

3.3.5
Maximum Percentage. A holder of a Warrant may notify Parent 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 Parent Class A Ordinary Shares outstanding immediately
after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of Parent Class A Ordinary
Shares beneficially owned by such person and its affiliates shall include the number of Parent Class A Ordinary Shares issuable
upon exercise of the Warrant with respect to which the determination of such sentence is being made, but shall exclude Parent
Class A 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 Parent beneficially owned by such person and its affiliates (including, without limitation, any convertible notes
or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained
herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated
in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For
purposes of the Warrant, in determining the number of outstanding Parent Class A Ordinary Shares, the holder may rely on the number
of outstanding Parent Class A Ordinary Shares as reflected in (1) Parent’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 Parent or (3) any other notice by Parent or the Warrant Agent setting forth the
number of Parent Class A Ordinary Shares outstanding. For any reason at any time, upon the written request of the holder of the
Warrant, Parent shall, within two (2) Business Days, confirm orally and in writing to such holder the number of Parent Class A
Ordinary Shares then outstanding. In any case, the number of outstanding Parent Class A Ordinary Shares shall be determined after
giving effect to the conversion or exercise of equity or debt securities of Parent by the holder and its affiliates since the
date as of which such number of outstanding Parent Class A Ordinary Shares was reported. By written notice to Parent, 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 Parent.

  

4.
Adjustments.

 

4.1.
Share Dividends; Split Ups. If after the Closing, the number of outstanding Parent Class A Ordinary Shares is increased
by a share dividend payable in Parent Class A Ordinary Shares, or by a split up of Parent Class A Ordinary Shares, or other similar
event, then, on the effective date of such share dividend, split up or similar event, the number of Parent Class A Ordinary Shares
issuable on exercise of each Warrant shall be increased in proportion to such increase in outstanding Parent Class A Ordinary
Shares.

 

4.2.
Aggregation of Shares. If after the Closing, the number of outstanding Parent Class A Ordinary Shares is decreased by a
consolidation, combination, reverse share split or reclassification of Parent Class A 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 Parent Class A Ordinary Shares issuable on exercise of each Warrant shall be decreased in proportion to such decrease in outstanding
Parent Class A Ordinary Shares.

 

4.3
Extraordinary Dividends. If Parent, 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 Parent Class A Ordinary Shares or other shares
of Parent’s capital 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 Parent’s Board of Directors, in good faith) of any securities or other assets
paid on each Parent Class A Ordinary Share 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
or (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 Parent Class A Ordinary Shares 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 Parent Class A Ordinary Shares 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. Solely for purposes of illustration, if Parent, 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 Parent Class A Ordinary Shares 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)).

  

    5

     

    

 

4.4
Adjustments in Exercise Price. Whenever the number of Parent Class A Ordinary Shares issuable 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 Parent Class A Ordinary Shares issuable upon the exercise of the Warrants immediately prior to such adjustment, and (y) the
denominator of which shall be the number of Parent Class A Ordinary Shares so issuable immediately thereafter.

 

4.5.
Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding
Parent Class A Ordinary Shares (other than a change covered by Section 4.1, 4.2 or 4.3 hereof or that solely affects the par value
of Parent Class A Ordinary Shares), or in the case of any merger or consolidation of Parent with or into another corporation (other
than a consolidation or merger in which Parent is the continuing corporation and that does not result in any reclassification
or reorganization of the outstanding Parent Class A Ordinary Shares), or in the case of any sale or conveyance to another corporation
or entity of the assets or other property of Parent as an entirety or substantially as an entirety in connection with which Parent
is dissolved, the Warrant holders shall thereafter have the right to subscribe for and receive, upon the basis and upon the terms
and conditions specified in the Warrants and in lieu of the Parent Class A Ordinary Shares immediately theretofore issuable 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 Parent Class A
Ordinary Shares 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, Parent 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 issuable 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, Parent 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 Warrants or Shares. No fractional Warrants will be held or issued hereunder. Additionally, notwithstanding
any provision contained in this Agreement to the contrary, Parent 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, Parent shall, upon such exercise, round up to the nearest whole
number of Parent Class A 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
delivered after such adjustment may state the same Warrant Price and the same number of shares as is stated in the Warrant initially
delivered pursuant to this Agreement. However, Parent may at any time in its sole discretion make any change in the form of Warrant
that Parent may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter delivered or countersigned,
whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed.

 

    6

     

    

 

4.9
Other Events. In case any event shall occur affecting Parent 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,
Parent 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. Parent 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. If the Warrant surrendered is in certificated form, such
surrendered Warrant shall be 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 delivered and
the old Warrant shall be cancelled by the Warrant Agent. The Warrants so cancelled shall be delivered by the Warrant Agent to
Parent from time to time upon request.

 

5.2.
Instrument of Transfer: The instrument of transfer of any Warrant may be executed for and on behalf of the transferor by
any party designated by the Board of Parent for such purpose, and Parent or any other party designated by the Board of Parent
for such purpose shall be deemed to have been irrevocably appointed agent for the transferor of such Warrant or Warrants with
full power to execute, complete and deliver in the name of and on behalf of the transferor of such Warrant or Warrants all such
transfers of Warrants held by the Warrant holders. Any document which records the name of the transferor, the name of the transferee,
the number of Warrants agreed to be transferred, the date of the agreement to transfer the Warrants and price per Warrants, shall,
once executed by the transferor or any other party designated by the Board of Parent for such purpose as agent for the transferor,
be deemed to be a proper instrument of transfer. The transferor shall be deemed to remain a Warrant holder until the name of the
transferee is entered on the Warrant Register in respect thereof, and neither the title of the transferee nor the title of the
transferor shall be affected by any irregularity or invalidity in the proceedings in reference to the sale should the Board of
Parent so determine.

 

5.3.
Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request
for exchange or transfer, and thereupon the Warrant Agent shall deliver in exchange therefor one or more new Warrants, in certificate
or book entry form, 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 deliver new Warrants in exchange therefor until the Warrant Agent has received an opinion
of counsel for Parent stating that such transfer may be made and indicating whether the new Warrants must also bear a restrictive
legend.

 

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

 

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

 

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

 

5.7
Fusion Fuel Warrants and Contingent Consideration Warrants. The Warrant Agent shall not register any transfer of Fusion
Fuel Warrants or Contingent Consideration Warrants until the date that is the one year anniversary of the Closing of the Business
Combination Agreement, except for transfers (i) to Parent’s officers, directors, initial shareholders, employees, consultants
or their affiliates, (ii) to a holder’s shareholders, officers, directors, employees or members upon the holder’s
liquidation, (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

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 Parent, at any time during the Exercise Period (so long as there is a current registration statement in effect with respect
to the Parent Class A Ordinary Shares 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 closing price of
the Parent Class A Ordinary Shares 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 that Parent shall elect to redeem all of the Warrants that are
subject to redemption, Parent shall fix a date for the redemption (the “Redemption Date”). Notice of redemption
shall be mailed by first class mail, postage prepaid, by Parent 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.

 

6.3.
Exercise After Notice of Redemption. The IPO 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 Parent pursuant to
Section 6.2 hereof and prior to the Redemption Date. In the event that Parent determines to require all holders of IPO Warrants
to exercise their IPO 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 Parent Class A Ordinary Shares to be received upon exercise of the Warrants,
including the “Fair Market Value” in such case and the aggregate nominal value to be paid for the relevant Parent
Class A Ordinary Shares which are the subject of such redemption notice. 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. Parent 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, Parent may redeem the Warrants issued upon such exercise provided
that the criteria for redemption is met. Additionally, Parent agrees that the redemption rights provided in this Section 6 shall
not apply to the Private Warrants if at the time of the redemption such Private Warrants continue to be held by the initial purchasers
or their permitted transferees. However, once any such Private Warrants are transferred (other than to permitted transferees under
Section 5.6), Parent may redeem such Private Warrants in the same manner as the IPO Warrants.

 

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 Parent, 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 Parent or any other matter.

 

7.2.
Lost, Stolen, Mutilated, or Destroyed Warrants. If any Warrant is lost, stolen, mutilated, or destroyed, Parent 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 Parent,
whether or not the allegedly lost, stolen, mutilated, or destroyed Warrant shall be at any time enforceable by anyone.

 

    8

     

    

 

7.3.
Reservation of Parent Class A Ordinary Shares. Parent shall at all times reserve and keep available a number of its authorized
but unissued Parent Class A 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 Parent Class A Ordinary Shares underlying IPO Warrants and Placement Warrants. On [●], 2020, the
registration statement on Form F-4 (Commission File No. 333-245052) registering the Parent Class A Ordinary Shares issuable upon
the exercise of the IPO Warrants and Placement Warrants was declared effective by the Commission. Parent will use its best efforts
to maintain the effectiveness of such registration statement until the expiration of the Warrants in accordance with the provisions
of this Agreement and to take such action as is necessary to register or qualify for sale, in those states in which the Warrants
were initially offered by Parent and in those states where holders of Warrants then reside, the Parent Class A Ordinary Shares
issuable upon exercise of the Warrants, to the extent an exemption is not available. During any period when Parent shall fail
to have maintained an effective registration statement covering the Parent Class A Ordinary Shares issuable upon exercise of the
Warrants, the holders of the Warrants shall have the right to exercise such Warrants on a “cashless basis” as determined
in accordance with Section 3.3.1. Parent shall provide the Warrant Agent with an opinion of counsel for Parent (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 Parent Class A 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 Parent 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, Parent 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.

 

8.1.
Payment of Taxes. Parent will from time to time promptly pay all taxes and charges that may be imposed upon Parent or the
Warrant Agent in respect of the issuance or delivery of Parent Class A Ordinary Shares upon the exercise of Warrants, but Parent
shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares. Parent, at its absolute discretion,
may, or may procure that a subsidiary of Parent shall, pay Irish stamp duty arising on a transfer of Warrants on behalf of the
transferee of such Warrants of Parent. If stamp duty resulting from the transfer of Warrants in Parent which would otherwise by
payable by the transferee is paid by Parent or any subsidiary of Parent on behalf of the transferee, then in those circumstances,
Parent shall, on its or on behalf of its subsidiary (as the case may be), be entitled to (i) reimbursement of the stamp duty from
the transferee, (ii) set-off an amount equal to the stamp duty against any Parent Class A Ordinary Shares issuable on exercise
of the Warrants and (ii) claim a first and paramount lien on the Warrants on which stamp duty has been paid by Parent or its subsidiary
for the amount of stamp duty paid.

 

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 Parent.
If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, Parent shall appoint in writing
a successor Warrant Agent in place of the Warrant Agent. If Parent 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 Parent), 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 Parent’s
cost. Any successor Warrant Agent, whether appointed by Parent 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 Parent, 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 Parent
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.

  

    9

     

    

 

8.2.2.
Notice of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, Parent shall give notice
thereof to the predecessor Warrant Agent and the transfer agent for the Parent Class A 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. Parent 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. Parent 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 Parent 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 Parent 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 an executive officer or the Chairman of the Board of Directors of Parent and delivered
to the Warrant Agent. The Warrant Agent may rely upon such statement for any action taken or suffered in good faith by it pursuant
to the provisions of this Agreement.

 

8.4.2.
Indemnity. The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct or bad faith.
Parent 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 (i) as
a result of the Warrant Agent’s gross negligence, willful misconduct, or bad faith; or (ii) any Tax imposed on or calculated
by reference to the net income received or receivable by the Warrant Agent. 

 

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 Parent 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 Parent Class A Ordinary Shares to be issued
pursuant to this Agreement or any Warrant or as to whether any Parent Class A 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 Parent with respect to Warrants
exercised and concurrently account for, and pay to Parent, all monies received by the Warrant Agent for the subscription of Parent
Class A Ordinary Shares through the exercise of Warrants.

bind and inure to the benefit of their respective successors and assigns.

 

9.2.

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

Notwithstanding the forgoing, nothing in this Section 9.3 shall limit or restrict the state or federal district court, as
applicable, in which a holder of any Warrant may bring a claim under the Securities Act of 1933, as amended, or the Exchange
Act from having jurisdiction over such claim. Any such process or summons to be served upon Parent 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

9.4.
Persons Having Rights under this Agreement. Nothing in this Agreement expressed and nothing that may be implied from any

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

beneficiary of this Agreement and may, as such, enforce the terms and provisions of this Agreement for its own benefit.

 

9.5.

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.

matter hereof and supersedes any prior agreements and understandings, both written and oral, among the Parties and any of their
respective affiliates with respect to the subject matter hereto. This Agreement may be amended by the parties hereto without the
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
Warrants; provided, that this Agreement may not be modified or amended in a manner that would negatively impact any holder or
group of holders differently from other holders without the written consent of such holder or a majority of such group of holders
negatively impacted, as applicable. Notwithstanding the foregoing, Parent may lower the Warrant Price or extend the duration of
the Exercise Period pursuant to Sections 3.1 and 3.2, respectively, without the consent of the registered holders.

  

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

REGISTRATION RIGHTS.

 

2.1
Demand Registration.

 

2.1.1 Request
for Registration. At any time and from time to time on or after the Triggering Date, the holders of a majority-in-interest
of all the outstanding Registrable Securities held by any of (i) the HL Investors, EBC, and the EBC Designees in respect of the
Registrable Securities held by them, (ii) the Fusion Fuel Shareholders in respect of the Registrable Securities held by them,
or (iii) the Directors in respect of the Registrable Securities held by them, as the case may be (but not including Escrow Shares
to the extent the Release Date has not occurred, the Fusion Fuel Securities to the extent the Lockup Expiration Date has not occurred,
the Director Shares to the extent any contractual transfer restrictions other than restrictions imposed by securities laws have
not lapsed, or the UPO Shares, which are covered by Section 2.1.2), may make a written demand for registration under the
Securities Act of all or part of their Registrable Securities (a “Demand Registration”). Any demand for a Demand
Registration shall specify the type and number of Registrable Securities proposed to be sold and the intended method(s) of distribution
thereof. Within ten (10) days of Parent’s receipt of the Demand Registration, Parent will notify all holders of Registrable
Securities of the demand (including the holders of the UPO Shares), and each holder of Registrable Securities who wishes to include
all or a portion of such holder’s Registrable Securities in the Demand Registration for which the applicable Triggering
Date has passed (each such holder including shares of Registrable Securities in such registration, a “Demanding Holder”)
shall so notify Parent within ten (10) days after the receipt by the holder of the notice from Parent. Upon any such request,
the Demanding Holders shall be entitled to have their Registrable Securities included in the Demand Registration, subject to Section
2.1.5 and the provisos set forth in Section 3.1.1. Parent shall not be obligated to effect more than an aggregate of two (2) Demand
Registrations under this Section 2.1.1 in respect of all Registrable Securities.

 

    4

    	 

    

 

2.1.2
UPO Shares Request for Registration. At any time and from time to time on or after the Triggering Date, the holders of
a majority-in-interest of the UPO Shares may make a written demand for registration under the Securities Act of all or part of
their UPO Shares (a “UPO Demand Registration”). Any demand for a UPO Demand Registration shall specify the
number of UPO Shares proposed to be sold and the intended method(s) of distribution thereof. Within ten (10) days of Parent’s
receipt of the UPO Demand Registration, Parent will notify all holders of Registrable Securities of the demand and each Demanding
Holder shall notify Parent of its wish to include all or a portion of such holder’s Registrable Securities in the UPO Demand
Registration within fifteen (15) days after the receipt by the holder of the notice from Parent. Upon any such request, the Demanding
Holders shall be entitled to have their Registrable Securities included in the UPO Demand Registration, subject to Section 2.1.5
and the provisos set forth in Section 3.1.1. Parent shall not be obligated to effect more than an aggregate of one (1) UPO Demand
Registration under this Section 2.1.2 in respect of all UPO Shares.

 

2.1.3
Effective Registration. A registration will not count as a Demand Registration or a UPO Demand Registration until the Registration
Statement filed with the Commission with respect to such Demand Registration or UPO Demand Registration has been declared effective
and Parent has complied with all of its obligations under this Amended and Restated Registration Rights Agreement with respect
thereto; provided, however, that if, after such Registration Statement has been declared effective, the offering of Registrable
Securities pursuant to a Demand Registration or UPO Demand Registration is interfered with by any stop order or injunction of
the Commission or any other governmental agency or court, the Registration Statement with respect to such Demand Registration
or UPO Demand Registration will be deemed not to have been declared effective, unless and until, (i) such stop order or injunction
is removed, rescinded or otherwise terminated, and (ii) a majority-in-interest of the Demanding Holders, on an As-Converted Basis,
thereafter affirmatively elect to continue the offering and notify Parent in writing, but in no event later than five (5) days
of such election; provided, further, that Parent shall not be obligated to file a second Registration Statement until a Registration
Statement that has been filed is counted as a Demand Registration or UPO Demand Registration or is terminated. 

 

2.1.4
Underwritten Offering. If a majority-in-interest of the Demanding Holders, on an As-Converted Basis, so elect and such
holders so advise Parent as part of their written demand for a Demand Registration or UPO Demand Registration, the offering of
such Registrable Securities pursuant to such Demand Registration or UPO Demand Registration shall be in the form of an underwritten
offering. In such event, the right of any holder to include its Registrable Securities in such registration shall be conditioned
upon such holder’s participation in such underwriting and the inclusion of such holder’s Registrable Securities in
the underwriting to the extent provided herein. All Demanding Holders proposing to distribute their Registrable Securities through
such underwriting shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected for
such underwriting by a majority-in-interest of the holders initiating the Demand Registration or UPO Demand Registration, as applicable,
on an As-Converted Basis.

 

    5

    	 

    

 

2.1.5
Reduction of Offering. If the managing Underwriter or Underwriters for a Demand Registration or UPO Demand Registration
that is to be an underwritten offering advises Parent and the Demanding Holders in writing that the dollar amount or number of
any Registrable Securities which the Demanding Holders desire to sell, taken together with all other Parent securities, if any,
as to which registration has been requested pursuant to written contractual piggy-back registration rights held by other shareholders
of Parent who desire to sell (the “Outside Registrable Securities” and together with the Registrable Securities,
the “Offering Securities”) and together with Parent Class A Ordinary Shares, warrants of Parent, or other equity
securities, or securities or other obligations exercisable or exchangeable for, or convertible into, equity securities, which
Parent desires to sell for its own account and/or for shareholders of Parent for their account(s) (the “Parent Offering
Securities”), exceeds the maximum dollar amount or maximum number of shares, warrants and/or other securities that can
be sold in such offering without adversely affecting the proposed offering price, the timing, the distribution method, or the
probability of success of such offering (such maximum dollar amount or maximum number of securities, as applicable, the “Maximum
Number of Securities”), then Parent shall include in such registration: (i) first, the amount of Offering Securities
that can be sold without exceeding the Maximum Number of Securities, such that the number of each type, series or class of Offering
Security registrable by a holder in a Demand Registration or UPO Demand Registration shall be determined on a pro rata basis in
respect of the total number of the same type, series or class of Offering Security requested be included in such registration
(such proportion is referred to herein as “Pro Rata”); and (ii) second, to the extent that the Maximum Number
of Securities has not been reached under the foregoing clause (i), the Parent Offering Securities that can be sold without exceeding
the Maximum Number of Securities.

 

2.1.6
Withdrawal. If a majority-in-interest of the Demanding Holders, on an As-Converted Basis, disapprove of the terms of any
underwriting or are not entitled to include all of their Registrable Securities in any offering, such majority-in-interest of
the Demanding Holders may elect to withdraw from such offering by giving written notice to Parent and the Underwriter or Underwriters
of their request to withdraw prior to the effectiveness of the Registration Statement filed with the Commission with respect to
such Demand Registration. If the majority-in-interest of the Demanding Holders, on an As-Converted Basis, withdraws from a proposed
offering relating to a Demand Registration or UPO Demand Registration, then such registration shall not count as a Demand Registration
provided for in Section 2.1.1 or 2.1.2, as applicable. 

 

2.2
Piggy-Back Registration.

 

2.2.1
Piggy-Back Rights. If at any time on or after the Closing Parent proposes to file a Registration Statement under the Securities
Act with respect to an offering of Parent Offering Securities (including, without limitation, pursuant to Section 2.1 and the
PIPE Registration Statement), other than a Registration Statement (i) filed in connection with any employee stock option or other
benefit plan, (ii) for an exchange offer or offering of securities solely to Parent’s existing shareholders, (iii) for an
offering of debt that is convertible into equity securities of Parent or (iv) for a dividend reinvestment plan, then Parent shall
(x) give written notice of such proposed filing to the holders of all Registrable Securities (but in each case only if such offering
is proposed to be made after the applicable Triggering Date), as soon as practicable but in no event less than ten (10) days before
the anticipated filing date, which notice shall describe the amount and type of securities to be included in such offering, the
intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, of the offering,
and (y) offer to the holders of Registrable Securities in such notice the opportunity to register the sale of such number of shares
of Registrable Securities as such holders may request in writing within five (5) days following receipt of such notice (a “Piggy-Back
Registration”). Parent shall cause such Registrable Securities to be included in such registration and shall use its
best efforts to cause the managing Underwriter or Underwriters of a proposed underwritten offering to permit the Registrable Securities
requested to be included in a Piggy-Back Registration on the same terms and conditions as any similar securities of Parent and
to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution
thereof. All holders of Registrable Securities proposing to distribute their securities through a Piggy-Back Registration that
involves an Underwriter or Underwriters shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters
selected for such Piggy-Back Registration.

 

    6

    	 

    

 

2.2.2
Reduction of Offering. If the managing Underwriter or Underwriters for a Piggy-Back Registration that is to be an underwritten
offering advises Parent and the holders of Registrable Securities in writing that the dollar amount or number of Parent Offering
Securities, taken together with the Outside Registrable Securities, the Registrable Securities as to which registration has been
requested under this Section 2.2 (the “Piggy-Back Registrable Securities”), and the Parent securities, if any,
as to which registration has been requested pursuant to the written contractual piggy-back registration rights of other shareholders
of Parent (the “Outside Piggy-Back Registrable Securities”), exceeds the Maximum Number of Securities, then
Parent shall include in any such registration:

 

(a)       If
the registration is undertaken for Parent’s account: (i) the Parent Offering Securities that can be sold without exceeding
the Maximum Number of Securities; (ii) second, to the extent that the Maximum Number of Securities has not been reached under
the foregoing clause (i), the Piggy-Back Registrable Securities as to which registration has been requested, Pro Rata, that can
be sold without exceeding the Maximum Number of Securities; and (iii) third, to the extent the Maximum Number of Securities has
not been reached under the foregoing clauses (i) and (ii), the Outside Piggy-Back Registrable Securities as to which registration
has been requested, Pro Rata, that can be sold without exceeding the Maximum Number of Securities; and

 

(b)       If
the registration is a “demand” registration undertaken at the demand of holders of Outside Registrable Securities,
(i) first, the Outside Registrable Securities that can be sold without exceeding the Maximum Number of securities; (ii) second,
to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), the Piggy-Back Registrable
Securities as to which registration has been requested, Pro Rata, that can be sold without exceeding the Maximum Number of Securities;
(iii) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii),
the Outside Piggy-Back Registrable Securities, Pro Rata, that can be sold without exceeding the Maximum Number of Securities;
and (iv) fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i), (ii),
and (iii), Parent Offering Securities.

 

2.2.3
Withdrawal. Any holder of Registrable Securities may elect to withdraw such holder’s request for inclusion of Registrable
Securities in any Piggy-Back Registration by giving written notice to Parent of such request to withdraw prior to the effectiveness
of the Registration Statement. Parent (whether on its own determination or as the result of a withdrawal by persons making a demand
pursuant to written contractual obligations) may withdraw a Registration Statement at any time prior to the effectiveness of such
Registration Statement. Notwithstanding any such withdrawal, Parent shall pay all expenses incurred by the holders of Registrable
Securities in connection with such Piggy-Back Registration as provided in Section 3.3. 

 

2.2.4
Unlimited Piggy Back Registration Rights. For purposes of clarity, any registration effected pursuant to Section 2.2 hereof
shall not be counted as a Demand Registration or UPO Demand Registration effected under Section 2.1 hereof.

 

    7

    	 

    

 

2.3
Registrations on Form F-3. The holders of Registrable Securities may at any time and from time to time after the applicable
Triggering Date, request in writing that Parent register the resale of any or all of such Registrable Securities on Form F-3 or
any similar short-form registration which may be available at such time (“Form F-3”); provided, however, that
Parent shall not be obligated to effect such request through an underwritten offering. Upon receipt of such written request, Parent
shall promptly give written notice of the proposed registration to all other holders of Registrable Securities, and each Demanding
Holder shall notify Parent of its wish to include all or a portion of such holder’s Registrable Securities in such Form
F-3 within ten (10) days after the receipt by the holder of the notice from Parent, and, as soon as practicable thereafter, but
not more than twelve (12) days after Parent’s initial receipt of such written request for a registration, Parent shall effect
the registration of all or such portion of such holder’s or holders’ Registrable Securities as are specified in such
request, together with all or such portion of the Registrable Securities or other securities of Parent, if any, of any other holder
or holders joining in such request; provided, however, that Parent shall not be obligated to effect any such registration pursuant
to this Section 2.3: (i) if Form F-3 is not available for such offering; or (ii) if the holders of the Registrable Securities,
together with the holders of any other securities of Parent entitled to inclusion in such registration, propose to sell Registrable
Securities and such other securities (if any) at any aggregate price to the public of less than $500,000. Registrations effected
pursuant to this Section 2.3 shall not be counted as Demand Registrations or UPO Demand Registration effected pursuant to Section
2.1.

 

3.
REGISTRATION PROCEDURES.

 

3.1
Filings; Information. Whenever Parent is required to effect the registration of any Registrable Securities pursuant to
Section 2, Parent shall use its best efforts to effect the registration and sale of such Registrable Securities in accordance
with the intended method(s) of distribution thereof as expeditiously as practicable, and in connection with any such request:

 

3.1.1
Filing Registration Statement. Parent shall use its best efforts to, as expeditiously as possible and in any event within
sixty (60) days after receipt of a request for a Demand Registration or UPO Demand Registration pursuant to Section 2.1, prepare
and file with the Commission a Registration Statement on any form for which Parent then qualifies or which counsel for Parent
shall deem appropriate and which form shall be available for the sale of all Registrable Securities to be registered thereunder
in accordance with the intended method(s) of distribution thereof, and shall use its best efforts to cause such Registration Statement
to become effective and use its best efforts to keep it effective for the period required by Section 3.1.3; provided, however,
that Parent shall have the right to defer any Demand Registration or UPO Demand Registration for up to thirty (30) days, and any
Piggy-Back Registration for such period as may be applicable to deferment of any demand registration to which such Piggy-Back
Registration relates, in each case if Parent shall furnish to the holders a certificate signed by the Chairman of the Board of
Directors or President of Parent stating that, in the good faith judgment of the Board of Directors of Parent, it would be materially
detrimental to Parent and its shareholders for such Registration Statement to be effected at such time; provided further, however,
that Parent shall not have the right to exercise the right set forth in the immediately preceding proviso more than once in any
365-day period in respect of a Demand Registration or UPO Demand Registration hereunder.

 

3.1.2
Copies. Parent shall, prior to filing a Registration Statement or prospectus, or any amendment or supplement thereto, furnish
without charge to the holders of Registrable Securities included in such registration, and such holders’ legal counsel,
copies of such Registration Statement as proposed to be filed, each amendment and supplement to such Registration Statement (in
each case including all exhibits thereto and documents incorporated by reference therein), the prospectus included in such Registration
Statement (including each preliminary prospectus), and such other documents as the holders of Registrable Securities included
in such registration or legal counsel for any such holders may request in order to facilitate the disposition of the Registrable
Securities owned by such holders.

 

    8

    	 

    

 

3.1.3
Amendments and Supplements. Parent shall prepare and file with the Commission such amendments, including post-effective
amendments, and supplements to such Registration Statement and the prospectus used in connection therewith as may be necessary
to keep such Registration Statement effective and in compliance with the provisions of the Securities Act until all Registrable
Securities and other securities covered by such Registration Statement have been disposed of in accordance with the intended method(s)
of distribution set forth in such Registration Statement or such securities have been withdrawn.

 

3.1.4
Notification. After the filing of a Registration Statement, Parent shall promptly, and in no event more than two (2) business
days after such filing, notify the holders of Registrable Securities included in such Registration Statement of such filing, and
shall further notify such holders promptly and confirm such advice in writing in all events within two (2) business days of the
occurrence of any of the following: (i) when such Registration Statement becomes effective; (ii) when any post-effective amendment
to such Registration Statement becomes effective; (iii) the issuance or threatened issuance by the Commission of any stop order
(and Parent shall take all actions required to prevent the entry of such stop order or to remove it if entered); and (iv) any
request by the Commission for any amendment or supplement to such Registration Statement or any prospectus relating thereto or
for additional information or of the occurrence of an event requiring the preparation of a supplement or amendment to such prospectus
so that, as thereafter delivered to the purchasers of the securities covered by such Registration Statement, such prospectus will
not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary
to make the statements therein not misleading, and promptly make available to the holders of Registrable Securities included in
such Registration Statement any such supplement or amendment; except that before filing with the Commission a Registration Statement
or prospectus or any amendment or supplement thereto, including documents incorporated by reference, Parent shall furnish to the
holders of Registrable Securities included in such Registration Statement and to the legal counsel for any such holders, copies
of all such documents proposed to be filed sufficiently in advance of filing to provide such holders and legal counsel with a
reasonable opportunity to review such documents and comment thereon, and Parent shall not file any Registration Statement or prospectus
or amendment or supplement thereto, including documents incorporated by reference, to which such holders or their legal counsel
shall object.

 

3.1.5
Securities Laws Compliance. Parent shall use its best efforts to (i) register or qualify the Registrable Securities covered
by the Registration Statement under such securities or “blue sky” laws of such jurisdictions in the United States
as the holders of Registrable Securities included in such Registration Statement (in light of their intended plan of distribution)
may request and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to
be registered with or approved by such other governmental authorities or securities exchanges, including the Nasdaq Capital Market,
as may be necessary by virtue of the business and operations of Parent and do any and all other acts and things that may be necessary
or advisable to enable the holders of Registrable Securities included in such Registration Statement to consummate the disposition
of such Registrable Securities in such jurisdictions; provided, however, that Parent shall not be required to qualify generally
to do business in any jurisdiction where it would not otherwise be required to qualify but for this paragraph or subject itself
to taxation in any such jurisdiction. 

 

    9

    	 

    

 

3.1.6
Agreements for Disposition. Parent shall enter into customary agreements (including, if applicable, an underwriting agreement
in customary form) and take such other actions as are reasonably required in order to expedite or facilitate the disposition of
such Registrable Securities. No holder of Registrable Securities included in such registration statement shall be required to
make any representations or warranties in the underwriting agreement except as reasonably requested by the Underwriters and, if
applicable, with respect to such holder’s organization, good standing, authority, title to Registrable Securities, lack
of conflict of such sale with such holder’s material agreements and organizational documents, and with respect to written
information relating to such holder that such holder has furnished in writing expressly for inclusion in such Registration Statement.

 

3.1.7
Cooperation. The principal executive officer of Parent, the principal financial officer of Parent, the principal accounting
officer of Parent and all other officers and members of the management of Parent shall cooperate fully in any offering of Registrable
Securities hereunder, which cooperation shall include, without limitation, the preparation of the Registration Statement with
respect to such offering and all other offering materials and related documents, and participation in meetings with Underwriters,
attorneys, accountants and potential investors.

 

3.1.8
Records. Parent shall make available for inspection by the holders of Registrable Securities included in such Registration
Statement, any Underwriter participating in any disposition pursuant to such registration statement and any attorney, accountant
or other professional retained by any holder of Registrable Securities included in such Registration Statement or any Underwriter,
all financial and other records, pertinent corporate documents and properties of Parent, as shall be necessary to enable them
to exercise their due diligence responsibility, and cause Parent’s officers, directors and employees to supply all information
requested by any of them in connection with such Registration Statement.

 

3.1.9
Opinions and Comfort Letters. Parent shall furnish to each holder of Registrable Securities included in any Registration
Statement a signed counterpart, addressed to such holder, of (i) any opinion of counsel to Parent delivered to any Underwriter
and (ii) any comfort letter from Parent’s independent public accountants delivered to any Underwriter. In the event no legal
opinion is delivered to any Underwriter, Parent shall furnish to each holder of Registrable Securities included in such Registration
Statement, at any time that such holder elects to use a prospectus, an opinion of counsel to Parent to the effect that the Registration
Statement containing such prospectus has been declared effective and that no stop order is in effect.

 

3.1.10
Earnings Statement. Parent shall comply with all applicable rules and regulations of the Commission and the Securities
Act, and make available to its shareholders, as soon as reasonably practicable, an earnings statement covering a period of twelve
(12) months, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder. 

 

3.1.11
Listing. Parent shall use its best efforts to cause all Registrable Securities included in any registration to be listed
on such exchanges or otherwise designated for trading in the same manner as similar securities issued by Parent are then listed
or designated or, if no such similar securities are then listed or designated, in a manner satisfactory to the holders of a majority
of the Registrable Securities included in such registration, on an As-Converted Basis.

 

    10

    	 

    

 

3.1.12.
Transfer Agent. Parent shall provide a transfer agent or warrant agent, as applicable, and registrar for all such Registrable
Securities no later than the effective date of the registration statement.

 

3.1.13. Misstatements.
Parent shall notify the Investors at any time when a prospectus relating to such Registration Statement is required to be delivered
under the Securities Act, of the happening of any event as a result of which the prospectus included in such Registration Statement,
as then in effect, includes an untrue statement of a material fact or an omission to state a material fact required to be stated
in a registration statement or prospectus, or necessary to make the statements therein in the light of the circumstances under
which they were made not misleading (a “Misstatement”), and then to correct such Misstatement.

 

 

3.2
Obligation to Suspend Distribution. Upon receipt of any notice from Parent of the happening of any event of the kind described
in Section 3.1.4(iv), or, in the case of a resale registration on Form F-3 pursuant to Section 2.3 hereof, upon any suspension
by Parent, pursuant to a written insider trading compliance program adopted by Parent’s Board of Directors, of the ability
of all “insiders” covered by such program to transact in Parent’s securities because of the existence of material
non-public information, each holder of Registrable Securities included in any registration shall immediately discontinue disposition
of such Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until such holder receives
the supplemented or amended prospectus contemplated by Section 3.1.4(iv) or the restriction on the ability of “insiders”
to transact in Parent’s securities is removed, as applicable, and, if so directed by Parent, each such holder will deliver
to Parent all written copies, other than permanent file copies then in such holder’s possession, of the most recent prospectus
covering such Registrable Securities at the time of receipt of such notice.

 

3.3
Registration Expenses. Parent shall bear all costs and expenses incurred in connection with any Demand Registration or
UPO Demand Registration pursuant to Section 2.1, any Piggy-Back Registration pursuant to Section 2.2, and any registration on
Form F-3 effected pursuant to Section 2.3, and all expenses incurred in performing or complying with its other obligations under
this Amended and Restated Registration Rights Agreement, whether or not the Registration Statement becomes effective, including,
without limitation: (i) all registration and filing fees and fees of any securities exchange on which the Parent Class A Ordinary
Shares, HL Parent Warrants and/or FF Parent Warrants are then listed; (ii) fees and expenses of compliance with securities or
“blue sky” laws (including fees and disbursements of counsel of the Underwriters in connection with blue sky qualifications
of the Registrable Securities); (iii) printing expenses; (iv) Parent’s internal expenses (including, without limitation,
all salaries and expenses of its officers and employees); (v) the fees and expenses incurred in connection with the listing of
the Registrable Securities as required by Section 3.1.11; (vi) Financial Industry Regulatory Authority fees; (vii) fees and disbursements
of counsel for Parent and fees and expenses for independent certified public accountants retained by Parent (including the expenses
or costs associated with the delivery of any opinions or comfort letters requested pursuant to Section 3.1.9); (viii) the fees
and expenses of any special experts retained by Parent in connection with such registration and (ix) the fees and expenses of
one legal counsel selected by the holders of a majority-in-interest of the Registrable Securities included in such registration.
Parent shall have no obligation to pay any underwriting discounts or selling commissions attributable to the Registrable Securities
being sold by the holders thereof, which underwriting discounts or selling commissions shall be borne by such holders. Additionally,
in an underwritten offering, all selling shareholders and Parent shall bear the expenses of the Underwriter pro rata in proportion
to the respective amount of shares each is selling in such offering. 

 

    11

    	 

    

 

3.4
Information. The holders of Registrable Securities shall provide such information as may reasonably be requested by Parent,
or the managing Underwriter, if any, in connection with the preparation of any Registration Statement, including amendments and
supplements thereto, in order to effect the registration of any Registrable Securities under the Securities Act pursuant to Section
2 and in connection with Parent’s obligation to comply with federal and applicable state securities laws.

 

3.5 Requirements
for Participation in Underwritten Offerings. No person may participate in any underwritten offering for equity securities
of Parent pursuant to a registration initiated by Parent hereunder unless such person (i) agrees to sell such person’s securities
on the basis provided in any underwriting arrangements approved by Parent and (ii) completes and executes all customary questionnaires,
powers of attorney, indemnities, lock-up agreements, underwriting agreements and other customary documents as may be reasonably
required under the terms of such underwriting arrangements.

 

3.6 Suspension
of Sales; Adverse Disclosure. Upon receipt of written notice from Parent that a registration statement or prospectus contains
a Misstatement, each of the holders of Registrable Securities shall forthwith discontinue disposition of Registrable Securities
until it has received copies of a supplemented or amended prospectus correcting the Misstatement (it being understood that Parent
hereby covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice), or until
it is advised in writing by Parent that the use of the prospectus may be resumed. If the filing, initial effectiveness or continued
use of a Registration Statement in respect of any registration at any time would require Parent to make an Adverse Disclosure
(as defined below) or would require the inclusion in such Registration Statement of financial statements that are unavailable
to Parent for reasons beyond Parent’s control, Parent may, upon giving prompt written notice of such action to the holders,
delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time,
but in no event more than thirty (30) days, determined in good faith by Parent to be necessary for such purpose. In the event
Parent exercises its rights under the preceding sentence, the Investors agree to suspend, immediately upon their receipt of the
notice referred to above, their use of the prospectus relating to any registration in connection with any sale or offer to sell
Registrable Securities. Parent shall immediately notify the Investors of the expiration of any period during which it exercised
its rights under this Section 3.6. As used herein, “Adverse Disclosure” means any public disclosure of material
non-public information, which disclosure, in the good faith judgment of the principal executive officer or principal financial
officer of Parent, after consultation with counsel to Parent, (i) would be required to be made in any Registration Statement or
prospectus in order for the applicable Registration Statement or prospectus not to contain any untrue statement of a material
fact or omit to state a material fact necessary to make the statements contained therein (in the case of any prospectus and any
preliminary prospectus, in the light of the circumstances under which they were made) not misleading, (ii) would not be required
to be made at such time if the Registration Statement were not being filed, and (iii) Parent has a bona fide business purpose
for not making such information public.

 

    12

    	 

    

 

3.7 Reporting
Obligations. As long as any Investor shall own Registrable Securities, Parent, at all times while it shall be reporting under
the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period)
all reports required to be filed by Parent after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to
promptly furnish the Investors with true and complete copies of all such filings. Parent will be deemed to have furnished the
Investors with copies of such filings upon the appearance of such filings on EDGAR and Parent’s website. Parent further
covenants that it shall take such further action as any Investor may reasonably request, all to the extent required from time
to time to enable such holder to sell Registrable Securities held by such Investor without registration under the Securities Act
within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act, including providing any legal
opinions. Upon the request of any Investor, Parent shall deliver to such Investor a written certification of a duly authorized
officer as to whether it has complied with such requirements.

 

4.
INDEMNIFICATION AND CONTRIBUTION.

 

4.1
Indemnification by Parent. Subject to the Irish Companies Act of 2014, in particular and without limitation, Section 82
thereunder, Parent agrees to indemnify and hold harmless each Investor and each other holder of Registrable Securities, and each
of their respective officers, employees, affiliates, directors, partners, members, attorneys and agents, and each person, if any,
who controls an Investor and each other holder of Registrable Securities (within the meaning of Section 15 of the Securities Act
or Section 20 of the Exchange Act) (each, an “Investor Indemnified Party”), from and against any expenses,
losses, judgments, claims, damages or liabilities, whether joint or several, arising out of or based upon any untrue statement
(or allegedly untrue statement) of a material fact contained in any Registration Statement under which the sale of such Registrable
Securities was registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained
in the Registration Statement, or any amendment or supplement to such Registration Statement, or arising out of or based upon
any omission (or alleged omission) to state a material fact required to be stated therein or necessary to make the statements
therein not misleading, or any violation by Parent of the Securities Act or any rule or regulation promulgated thereunder applicable
to Parent and relating to action or inaction required of Parent in connection with any such registration; and Parent shall promptly
reimburse the Investor Indemnified Party for any legal and any other expenses reasonably incurred by such Investor Indemnified
Party in connection with investigating and defending any such expense, loss, judgment, claim, damage, liability or action whether
or not any such person is a party to any such claim or action and including any and all legal and other expenses incurred in giving
testimony or furnishing documents in response to a subpoena or otherwise; provided, however, that Parent will not be liable in
any such case to the extent that any such expense, loss, claim, damage or liability arises out of or is based upon any untrue
statement or allegedly untrue statement or omission or alleged omission made in such Registration Statement, preliminary prospectus,
final prospectus, or summary prospectus, or any such amendment or supplement, in reliance upon and in conformity with information
furnished to Parent, in writing, by such selling holder expressly for use therein. Parent also shall indemnify any Underwriter
of the Registrable Securities, their officers, affiliates, directors, partners, members and agents and each person who controls
such Underwriter on substantially the same basis as that of the indemnification provided above in this Section 4.1. 

 

    13

    	 

    

 

4.2
Indemnification by Holders of Registrable Securities. Subject to the limitations set forth under Section 4.4.3 hereof,
each selling holder of Registrable Securities will, in the event that any registration is being effected under the Securities
Act pursuant to this Amended and Restated Registration Rights Agreement of any Registrable Securities held by such selling holder,
indemnify and hold harmless Parent, each of its directors and officers and each Underwriter (if any), and each other selling holder
and each other person, if any, who controls another selling holder or such Underwriter within the meaning of the Securities Act,
against any losses, claims, judgments, damages or liabilities, whether joint or several, insofar as such losses, claims, judgments,
damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or allegedly untrue
statement of a material fact contained in any Registration Statement under which the sale of such Registrable Securities was registered
under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained in the Registration Statement,
or any amendment or supplement to the Registration Statement, or arise out of or are based upon any omission or the alleged omission
to state a material fact required to be stated therein or necessary to make the statement therein not misleading, if the statement
or omission was made in reliance upon and in conformity with information furnished in writing to Parent by such selling holder
expressly for use therein, and shall reimburse Parent, its directors and officers, and each other selling holder or controlling
person for any legal or other expenses reasonably incurred by any of them in connection with investigation or defending any such
loss, claim, damage, liability or action. Each selling holder’s indemnification obligations hereunder shall be several and
not joint and shall be limited to the amount of any net proceeds actually received by such selling holder. Each selling holder
of Registrable Securities shall indemnify any Underwriter of the Registrable Securities, the Underwriter’s officers, affiliates,
directors, partners, members, and agents, and each person who controls such Underwriter to the same extent as provided herein
with respect to Parent.

 

4.3
Conduct of Indemnification Proceedings. Promptly after receipt by any person of any notice of any loss, claim, damage or
liability or any action in respect of which indemnity may be sought pursuant to Section 4.1 or 4.2, such person (the “Indemnified
Party”) shall, if a claim in respect thereof is to be made against any other person for indemnification hereunder, notify
such other person (the “Indemnifying Party”) in writing of the loss, claim, judgment, damage, liability or
action; provided, however, that the failure by the Indemnified Party to notify the Indemnifying Party shall not relieve the Indemnifying
Party from any liability which the Indemnifying Party may have to such Indemnified Party hereunder, except and solely to the extent
the Indemnifying Party is actually prejudiced by such failure. If the Indemnified Party is seeking indemnification with respect
to any claim or action brought against the Indemnified Party, then the Indemnifying Party shall be entitled to participate in
such claim or action, and, to the extent that it wishes, jointly with all other Indemnifying Parties, to assume control of the
defense thereof with counsel satisfactory to the Indemnified Party. After notice from the Indemnifying Party to the Indemnified
Party of its election to assume control of the defense of such claim or action, the Indemnifying Party shall not be liable to
the Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that in any action in which both the Indemnified Party
and the Indemnifying Party are named as defendants, the Indemnified Party shall have the right to employ separate counsel (but
no more than one such separate counsel) to represent the Indemnified Party and its controlling persons who may be subject to liability
arising out of any claim in respect of which indemnity may be sought by the Indemnified Party against the Indemnifying Party,
with the fees and expenses of such counsel to be paid by such Indemnifying Party if, based upon the written opinion of counsel
of such Indemnified Party, representation of both parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, consent
to entry of judgment or effect any settlement of any claim or pending or threatened proceeding in respect of which the Indemnified
Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such judgment
or settlement includes an unconditional release of such Indemnified Party from all liability arising out of such claim or proceeding.

4.4
Contribution.

 

4.4.1
If the indemnification provided for in the foregoing Sections 4.1, 4.2 and 4.3 is unavailable to any Indemnified Party in respect
of any loss, claim, damage, liability or action referred to herein, then each such Indemnifying Party, in lieu of indemnifying
such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, claim,
damage, liability or action in such proportion as is appropriate to reflect the relative fault of the Indemnified Parties and
the Indemnifying Parties in connection with the actions or omissions which resulted in such loss, claim, damage, liability or
action, as well as any other relevant equitable considerations. The relative fault of any Indemnified Party and any Indemnifying
Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to information supplied by such Indemnified Party or such
Indemnifying Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

 

4.4.2
The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.4 were determined
by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred
to in the immediately preceding Section 4.4.1.

 

4.4.3
The amount paid or payable by an Indemnified Party as a result of any loss, claim, damage, liability or action referred to in
the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other
expenses incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding
the provisions of this Section 4.4, no holder of Registrable Securities shall be required to contribute any amount in excess of
the dollar amount of the net proceeds (after payment of any underwriting fees, discounts, commissions or taxes) actually received
by such holder from the sale of Registrable Securities which gave rise to such contribution obligation. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act) with respect to any action shall be entitled to
contribution in such action from any person who was not guilty of such fraudulent misrepresentation.

 

4.5 Survival.
The indemnification provided for under this Amended and Restated Registration Rights Agreement shall remain in full force and
effect regardless of any investigation made by or on behalf of the Indemnified Party or any officer, director or controlling person
of such Indemnified Party and shall survive the transfer of securities.

 

5.
RULE 144. Parent covenants that it shall file any reports required to be filed by it under the Securities Act and the Exchange
Act and shall take such further action as the holders of Registrable Securities may reasonably request, all to the extent required
from time to time to enable such holders to sell Registrable Securities without registration under the Securities Act within the
limitation of the exemptions provided by Rule 144 under the Securities Act, as such Rules may be amended from time to time, or
any similar rule or regulation hereafter adopted by the Commission.

6.
MISCELLANEOUS.

 

6.1
Other Registration Rights. Except for the registration rights granted to the PIPE investors under each of their respective
subscription agreements, dated on or around August 25, 2020, Parent represents and warrants that no person other than the holders
of the Registrable Securities has any right to require Parent to register any shares of Parent’s capital stock for sale
or to include shares of Parent’s capital stock in any registration filed by Parent for the sale of shares of capital stock
for its own account or for the account of any other person. Further, except with respect to the registration rights granted to
the PIPE Investors, Parent represents and warrants that this Agreement supersedes any other registration rights agreement or agreement
with similar terms and conditions and in the event of a conflict between any such agreement or agreements and this Amended and
Restated Registration Rights Agreement, the terms of this Amended and Restated Registration Rights Agreement shall prevail.

 

6.2
Assignment; No Third Party Beneficiaries. This Amended and Restated Registration Rights Agreement and the rights, duties
and obligations of Parent hereunder may not be assigned or delegated by Parent in whole or in part. This Amended and Restated
Registration Rights Agreement and the rights, duties and obligations of the holders of Registrable Securities hereunder may be
freely assigned or delegated by such holder of Registrable Securities in conjunction with and to the extent of any transfer of
Registrable Securities by any such holder. This Amended and Restated Registration Rights Agreement and the provisions hereof shall
be binding upon and shall inure to the benefit of each of the parties, to the permitted assigns of the Investors or holder of
Registrable Securities or of any assignee of the Investors or holder of Registrable Securities. This Amended and Restated Registration
Rights Agreement is not intended to confer any rights or benefits on any persons that are not party hereto other than as expressly
set forth in Article 4 and this Section 6.2. No assignment by any party hereto of such party’s rights, duties, and obligations
hereunder shall be binding upon or obligate Parent unless and until Parent shall have received (i) written notice of such assignment
and (ii) the written assignment of the assignee, in a form reasonably satisfactory to Parent, to be bound by the terms and provisions
of this Amended and Restated Registration Rights Agreement (which may be accomplished by an addendum or certificate of joinder
to this Amended and Restated Registration Rights Agreement).

 

6.3
Notices. All notices, demands, requests, consents, approvals or other communications (collectively, “Notices”)
required or permitted to be given hereunder or which are given with respect to this Amended and Restated Registration Rights Agreement
shall be in writing and shall be personally served, delivered by reputable air courier service with charges prepaid, or transmitted
by hand delivery, telegram, telex or facsimile, addressed as set forth below, or to such other address as such party shall have
specified most recently by written notice. Notice shall be deemed given on the date of service or transmission if personally served
or transmitted by telegram, telex or facsimile; provided, that if such service or transmission is not on a business day or is
after normal business hours, then such notice shall be deemed given on the next business day. Notice otherwise sent as provided
herein shall be deemed given on the next business day following timely delivery of such notice to a reputable air courier service
with an order for next-day delivery.

6.4
Severability. This Amended and Restated Registration Rights 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 Amended and Restated
Registration Rights 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 Amended and Restated Registration Rights
Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible that is valid and enforceable.

 

6.5
Counterparts. This Amended and Restated Registration Rights Agreement may be executed in multiple counterparts, each of
which shall be deemed an original, and all of which taken together shall constitute one and the same instrument. Delivery of a
signed counterpart of this Amended and Restated Registration Rights Agreement by facsimile or email/pdf transmission shall constitute
valid and sufficient delivery thereof.

 

6.6
Entire Agreement. This Amended and Restated Registration Rights Agreement (including all agreements entered into pursuant
hereto and all certificates and instruments delivered pursuant hereto and thereto) constitute the entire agreement of the parties
with respect to the subject matter hereof and supersede all prior and contemporaneous agreements, representations, understandings,
negotiations and discussions between the parties, whether oral or written.

 

6.7
Modifications and Amendments. Upon the written consent of Parent and the holders of at least sixty-six and two-thirds percent
(66-2/3%) of the Registrable Securities, on an As-Converted Basis, at the time in question, compliance with any of the provisions,
covenants and conditions set forth in this Amended and Restated Registration Rights Agreement may be waived, or any of such provisions,
covenants or conditions may be amended or modified; provided, however, that notwithstanding the foregoing, any amendment hereto
or waiver hereof that adversely affects one holder of Registrable Securities or group of holders of Registrable Securities, solely
in its or their capacity(ies) as a holder(s) of Registrable Securities, in a manner that is materially different from the other
holders of Registrable Securities (in such capacity) shall require the consent of the holder(s) so affected; for the sake of clarity
and by way of example, any such amendment or waiver that adversely affects the Fusion Fuel Shareholders in a manner that is materially
different from the other holders of Registrable Securities shall require the consent of the holders of a majority in interest
of the Fusion Fuel Securities, on an As-Converted Basis. No course of dealing between any holders of Registrable Securities or
Parent and any other party hereto or any failure or delay on the part of a holder of Registrable Securities or Parent in exercising
any rights or remedies under this Agreement shall operate as a waiver of any rights or remedies of any holder of Registrable Securities
or Parent. No single or partial exercise of any rights or remedies under this Amended and Restated Registration Rights Agreement
by a party shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by such
party.

 

    18

    	 

    

 

6.8
Titles and Headings. Titles and headings of sections of this Amended and Restated Registration Rights Agreement are for
convenience only and shall not affect the construction of any provision of this Amended and Restated Registration Rights Agreement.

 

6.9
Waivers and Extensions. Any party to this Amended and Restated Registration Rights Agreement may waive any right, breach
or default which such party has the right to waive, provided that such waiver will not be effective against the waiving party
unless it is in writing, is signed by such party, and specifically refers to this Amended and Restated Registration Rights Agreement.
Waivers may be made in advance or after the right waived has arisen or the breach or default waived has occurred. Any waiver may
be conditional. No waiver of any breach of any agreement or provision herein contained shall be deemed a waiver of any preceding
or succeeding breach thereof nor of any other agreement or provision herein contained. No waiver or extension of time for performance
of any obligations or acts shall be deemed a waiver or extension of the time for performance of any other obligations or acts.

 

6.10
Remedies Cumulative. In the event that Parent fails to observe or perform any covenant or agreement to be observed or performed
under this Amended and Restated Registration Rights Agreement, the Investor or any other holder of Registrable Securities may
proceed to protect and enforce its rights by suit in equity or action at law, whether for specific performance of any term contained
in this Amended and Restated Registration Rights Agreement or for an injunction against the breach of any such term or in aid
of the exercise of any power granted in this Amended and Restated Registration Rights Agreement or to enforce any other legal
or equitable right, or to take any one or more of such actions, without being required to post a bond. None of the rights, powers
or remedies conferred under this Amended and Restated Registration Rights Agreement shall be mutually exclusive, and each such
right, power or remedy shall be cumulative and in addition to any other right, power or remedy, whether conferred by this Amended
and Restated Registration Rights Agreement or now or hereafter available at law, in equity, by statute or otherwise. 

 

6.11
Governing Law. This Amended and Restated Registration Rights Agreement shall be governed by, interpreted under, and construed
in accordance with the internal laws of the State of New York applicable to agreements made and to be performed within the State
of New York, without giving effect to any choice-of-law provisions thereof that would compel the application of the substantive
laws of any other jurisdiction. Parent and each Investor irrevocably submits to the nonexclusive jurisdiction of any New York
State or United States Federal court sitting in The City of New York, Borough of Manhattan, over any suit, action or proceeding
arising out of or relating to this Amended and Restated Registration Rights Agreement. Parent and each Investor irrevocably waives,
to the fullest extent permitted by law, any objection that he, she, or it may now or hereafter have to the laying of venue of
any such suit, action or proceeding brought in such a court and any claim that any such suit, action or proceeding brought in
such a court has been brought in an inconvenient forum.

 

6.12
Waiver of Trial by Jury. Each party hereby irrevocably and unconditionally waives
the right to a trial by jury in any action, suit, counterclaim or other proceeding (whether based on contract, tort or otherwise)
arising out of, connected with or relating to this AMENDED AND RESTATED REGISTRATION RIGHTS Agreement, the transactions contemplated
hereby, or the actions of the Investor in the negotiation, administration, performance or enforcement hereof.
