2. REGISTRATION
RIGHTS.

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. 

 

    14 

     

    

 

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. 

 

    15 

     

    

 

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

RECITALS

 

A. WHEREAS,
Parent, HL, the Company, the Company Shareholders, and the other parties thereto have entered into a Business Combination
Agreement dated as of June 6, 2020, as amended and restated on August 25, 2020 (as may be further amended from time to time,
the “Business Combination Agreement”), pursuant to which (i) Fusion Fuel Atlantic Limited, a British
Virgin Islands business company and wholly owned subsidiary of Parent, will merge with and into HL with HL being the
surviving entity of such merger (the “Merger”) and becoming a wholly-owned subsidiary of Parent, followed
immediately by (ii) the acquisition by Parent of all of the issued and outstanding shares of the Company (the “Share
Exchange”, and together with the Merger, the “Transactions”).

 

B. WHEREAS, upon consummation of the Share Exchange, each Company Shareholder will receive its pro rata portion of an aggregate
of 2,125,000 Class B ordinary shares of Parent (“Parent Class B Ordinary Shares”) and warrants to purchase
an aggregate of 2,125,000 Class A ordinary shares of Parent (“Parent Class A Ordinary Shares”), and the Company
Shareholders will be allotted the right to receive a portion of up to an aggregate of an additional 1,137,000 Parent Class A Ordinary
Shares and warrants to purchase up to an aggregate of 1,137,000 Parent Class A Ordinary Shares upon the satisfaction of certain
earnout targets.

 

C. WHEREAS, the Business Combination Agreement contemplates the execution and delivery of this Agreement and the deposit by Parent
with the Escrow Agent of 212,500 Parent Class B Ordinary Shares (the “Escrow Shares”), allocated among the
Company Shareholders in the same proportions as the total Company Consideration is allocated among them, to satisfy any Losses
that are recoverable against the Company Shareholders pursuant to and in accordance with the Business Combination Agreement.

 

D. WHEREAS, capitalized terms not defined herein shall have the meaning ascribed to such terms in the Business Combination Agreement.

 

     

     

    

 

AGREEMENT

 

NOW,
THEREFORE, in consideration of the premises and the mutual promises herein made, and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the Escrow Parties and Escrow Agent, intending to be legally bound,
agree as follows:

 

Section
1.Escrow.

 

1.1 Appointment; Shares Placed in Escrow. The Escrow Parties hereby appoint the Escrow Agent as their escrow agent for
the purposes set forth herein, and the Escrow Agent hereby accepts such appointment and agrees to act as escrow agent in accordance
with the terms and conditions set forth herein. Simultaneously with the execution and delivery of this Agreement, Parent shall
instruct the Escrow Agent to include an escrow legend and stop transfer order against the book entry positions representing the
Escrow Shares, and to issue such restricted book entry positions in the name of the Company Shareholders and in the amounts as
set forth on Exhibit A hereto, which, for the avoidance of doubt, have been calculated in the same proportions as the Parent
Class B Ordinary Shares are allocated among the Company Shareholders, together with an assignment separate from each such certificate
executed in blank by each such Company Shareholder, with medallion signature guarantees.

 

1.2 Escrow Account. The Escrow Agent will issue its written confirmation of the receipt of the Escrow Shares and, upon
delivery, shall hold the Escrow Shares in an account established with the Escrow Agent, with a separate account for each Company
Shareholder’s portion of the Escrow Shares, subject to the terms of Section 3 below (collectively, the “Escrow
Account”).

 

1.3 Trust Fund. The Escrow Shares shall be held, by way of security, on bare trust and shall not be subject to any lien,
attachment, trustee process or any other judicial process of any creditor of any Escrow Party or any of its respective affiliates.
The Escrow Agent shall hold and safeguard the Escrow Shares until the Termination Date (as defined in Section 5) or earlier
release in accordance with this Agreement.

 

1.4 Rights as Shareholders. Except as otherwise provided in this Agreement, the Company Shareholders shall retain all of
their rights as shareholders of Parent with respect to the Escrow Shares while such remain in the Escrow Account, including, without
limitation, the right of the Company Shareholders to vote their Parent Class B Ordinary Shares included in the Escrow Shares.

 

1.5 Dividends. All dividends payable in cash with respect to the Escrow Shares held in the Escrow Account shall be paid
to the Company Shareholders in the same proportions as the Parent Class B Ordinary Shares are allocated among them, but all dividends
payable in stock or other non-cash property (“Non-Cash Dividends”) shall be delivered to the Escrow Agent to
hold in accordance with the terms hereof. As used herein, the term “Escrow Fund” shall be deemed to include
the Non-Cash Dividends distributed thereon, if any.

 

    2

     

    

 

1.6 Transfers. The Company Shareholder Representative acknowledges on behalf of the Company Shareholders that the Escrow
Shares are subject to lock-up provisions set forth in the Business Combination Agreement. In the event a Company Shareholder makes
a transfer prior to the end of the lock-up period as set forth in the Business Combination Agreement with respect to his, her,
or its Escrow Shares, the Company Shareholder Representative shall deliver to the Escrow Agent, on behalf of the transferring
Company Shareholder, (i) an assignment separate from certificate executed by the transferring Company Shareholder, with medallion
signature guaranty, evidencing the transfer of the Escrow Shares, (ii) an assignment separate from certificate executed in blank
by the transferee with medallion signature guaranty, with respect to the transferred Escrow Shares and (iii) a written acknowledgement
of the transferee that the transferred Escrow Shares are subject to this Agreement and, if applicable, the transfer has been duly
stamped by the Irish Revenue Commissioners. Upon receipt of such documents, the Escrow Agent shall deliver to Parent’s transfer
agent the original certificate(s) representing the Escrow Shares which have been transferred, together with the executed assignment
separate from certificate executed by the transferring Company Shareholder, and shall request that Parent issue new certificates
representing the number of Escrow Shares, if any, that continue to be owned by the transferring Company Shareholder and the number
of Escrow Shares owned by the transferee as the result of such transfer. The Escrow Agent shall place the new certificates representing
the Escrow Shares owned by the transferee and by the transferring Company Shareholder into escrow and shall update Exhibit
A hereto. Parent, the transferring Company Shareholder and the transferee shall cooperate in all respects with the Escrow
Agent in documenting each such transfer and in effectuating the result intended to be accomplished thereby.

 

Section
2.Release of Escrow.

 

The
Escrow Shares held pursuant to this Agreement are intended to provide an exclusive remedy in respect of indemnification claims
brought pursuant to the Business Combination Agreement. The Parties shall act in accordance with, and the Escrow Agent shall hold
as bare trustee, and release the Escrow Shares, as provided in, this Section 2.

 

2.1 Indemnification Related Claims.

 

(a) At any time and from time to time on or prior to the Escrow Termination Date, the HL Representative, acting on behalf of any HL
Indemnitee, may make a claim for indemnification pursuant to and in accordance with Article XI of the Business Combination Agreement
(a “Claim”) by delivering to the Escrow Agent and Parent a Notice of Claim setting forth (i) the information
required to be included in a Notice of Claim pursuant to the Business Combination Agreement and (ii) the estimated number of Escrow
Shares to be forfeited and cancelled in satisfaction of the Claim.

 

    3

     

    

 

(b) If the Escrow Agent has not received a written objection to such Claim or portion thereof or the amount of such Claim from Parent
within twenty (20) calendar days following the Escrow Agent’s and Parent’s receipt of the Notice of Claim, the HL
Representative shall promptly calculate the Fair Market Value (as defined below) of the Escrow Shares to be reviewed and confirmed
by Parent, and Parent and the HL Representative shall deliver a joint instruction (“Forfeiture Instruction”)
to the Escrow Agent to release for forfeiture and cancellation such number of Escrow Shares equal to the quotient of (i)
the amount of Loss as set forth in the Notice of Claim divided by (ii) the Fair Market Value. Upon the Escrow Agent’s
receipt of the Forfeiture Instruction, the Escrow Agent shall release for forfeiture and cancellation the number of Escrow Shares
as set forth in the Forfeiture Instruction from the accounts maintained on behalf of each Company Shareholder in the same proportion
that the total Company Consideration is allocated among them. In no event shall the Escrow Agent be required to calculate Fair
Market Value or make a determination of the number of Escrow Shares to be forfeited and cancelled in satisfaction of any Claim
in the aggregate or from the account maintained on behalf of any particular Company Shareholder. The Escrow Parties agree that
the foregoing right to satisfy Claims by the cancellation and forfeiture of any Escrow Shares may be made notwithstanding any
other agreements restricting or limiting the ability of any Company Shareholder to sell or transfer any Escrow Shares of Parent
or otherwise.

  

(c) If Parent in good faith delivers to the Escrow Agent and HL Representative a written objection (a “Dispute Notice”)
to any Claim or portion thereof or to the amount of such Claim within twenty (20) calendar days following both the Escrow Agent’s
and Parent’s receipt of the Notice of Claim, then the Escrow Agent shall not release any of the Escrow Shares that are the
subject of the Dispute Notice until the Escrow Agent receives either (i) a Forfeiture Instruction signed by Parent and the HL
Representative authorizing the release of such number of Escrow Shares for cancellation and forfeiture in satisfaction of the
Claim or (ii) a Final Determination directing the release for cancellation and forfeiture of such number of Escrow Shares as set
forth in the Final Determination or, if the Final Determination determines the dollar value of the Claim but does not calculate
the number of Escrow Shares to be forfeited and cancelled, in a Forfeiture Instruction delivered by the HL Representative and
Parent together with the Final Determination. Notwithstanding the foregoing, if Parent objects only in part to the amount of the
Claim, then after the lapse of the aforementioned twenty (20) calendar day period the HL Representative and Parent shall submit
a Forfeiture Instruction to the Escrow Agent setting forth the portion of the Claim not objected to by Parent, pursuant to Section
2.1(b). Upon receipt of a Final Determination and/or Forfeiture Instruction, as the case may be, the Escrow Agent shall release
such number of Escrow Shares in the Escrow Account in accordance with such Final Determination and/or Forfeiture Instruction.

 

(d) Notwithstanding anything to the contrary herein, no Claim shall be payable unless and until the aggregate amount of indemnifiable
Losses exceeds €750,000 (“Threshold”), in which case all Losses that exceed the Threshold shall be indemnifiable.

 

2.2 Release
of Remaining Escrow.

 

(a) On the tenth (10th) Business Day after Parent files its annual report for the year ending December 31, 2021 (“Escrow
Termination Date”), the Escrow Agent shall release the Escrow Shares remaining in the Escrow Account, less such number
of Escrow Shares representing the value of any Unresolved Claims (defined below), to the Company Shareholders in accordance with
Joint Release Instructions specifying the number of Escrow Shares to be distributed to each Company Shareholder (or transferee
pursuant to Section 1.6 hereof).

 

    4

     

    

 

(b) Unresolved Claims for which Parent has objected in accordance with Section 2.1 shall be administered in accordance with
Section 2.1(c).

  

(c) Upon the expiration of the twenty (20) calendar day objection period for any Unresolved Claims for which no Dispute Notice has
been delivered, Parent and the HL Representative shall submit a Forfeiture Instruction to the Escrow Agent setting forth the portion
of the Claim not objected to by Parent, and the Escrow Agent shall release such number of Escrow Shares for forfeiture and cancellation
as set forth in the Forfeiture Instruction, pursuant to Section 2.1(b).

 

(d) After the resolution of each Unresolved Claim, any remaining portion of the Escrow Account not released for cancellation and forfeiture
and not subject to other Unresolved Claims shall be released promptly thereafter by the Escrow Agent to the Company Shareholders
in accordance with a Joint Release Instruction.

 

2.3 Court
Order. Notwithstanding any other provision in this Agreement to the contrary, the Escrow Agent shall release the Escrow Account
(or any portion thereof) in accordance with a notice from either Parent or the HL Representative of a Final Determination, along
with a copy of the order, pursuant to which such court has determined whether and to what extent either the Escrow Shares shall
be forfeited and cancelled or the Company Shareholders are entitled to the Escrow Shares, as applicable. If the Final Determination
determines the dollar value of the Claim but does not calculate the number of Escrow Shares to be forfeited and cancelled, Parent
and the HL Representative shall deliver a Forfeiture Instruction together with the Final Determination showing the number of Escrow
Shares to be forfeited and cancelled from the accounts maintained on behalf of each Company Shareholder.

 

2.4 Claims in Excess of Escrow. If at any time during the term of this Agreement the number of Escrow Shares required to
be released for cancellation and forfeiture pursuant to Section 2.1 exceeds the number of Escrow Shares remaining in the
Escrow Account, the Escrow Agent shall release the entire Escrow Account for cancellation and forfeiture and the rights of the
HL Indemnitees to indemnification under Article XI the Business Combination Agreement shall be satisfied in full and extinguished.

 

2.5 Call Back Authorized Individuals. In the event a Joint Release Instruction is delivered to the Escrow Agent, whether
by e-mail, facsimile, mail, courier or otherwise, the Escrow Agent is authorized to seek confirmation of such instruction by telephone
call back to the person or persons designated in Exhibits B-1 and/or B-2 annexed hereto (the “Call Back
Authorized Individuals”), and the Escrow Agent may rely upon the confirmations of anyone purporting to be a Call Back
Authorized Individual. To ensure accuracy of the instructions it receives, the Escrow Agent may record such call backs. If the
Escrow Agent is unable to verify the instructions, or is not satisfied with the verification it receives, it will not execute
the instruction until all such issues have been resolved. The persons and telephone numbers for call backs may be changed only
in writing actually received and acknowledged by the Escrow Agent.

 

    5

     

    

 

2.6 Certain Definitions.

 

(a) “Business Day” means any day that is not a Saturday, a Sunday, or other day on which commercial banks located
in New York, New York or Dublin, Ireland are obligated or authorized by applicable law to remain closed for business.

  

(b) “Fair Market Value” of the Escrow Shares means a price per share equal to the five-day trailing average of
the mean of the high and low trading prices of Parent Class A Ordinary Shares on the Nasdaq Capital Market as of the five trading
days immediately preceding the satisfaction of such Losses.

 

(c) “Final Determination” means a final non-appealable order of any court of competent jurisdiction which may be
issued in respect of a Claim, together with (i) a certificate of the prevailing Escrow Party(ies) to the effect that such judgment
is final and non-appealable and from a court of competent jurisdiction having proper authority and (ii) the written instructions
of the prevailing Escrow Party(ies), provided that if the Final Determination directs the forfeiture and cancellation of Escrow
Shares, Parent shall countersign the written instructions to confirm that the number of Escrow Shares to be forfeited and cancelled
from each Company Shareholder’s account has been verified by Parent.

 

(d) “Joint Release Instruction” means a joint written instruction of Parent and HL Representative, which is executed
by Parent and HL Representative, to the Escrow Agent directing the Escrow Agent to release all or a portion of the Escrow Account,
as applicable.

 

(e) “Person” means any individual, general or limited partnership, firm, corporation, limited liability company,

Escrow Termination Date.

 

Section
3.Fees and Expenses. 

 

The
Escrow Agent shall be entitled to receive, from time to time, fees in accordance with Schedule 1. In accordance with Schedule

the Escrow Agent in the performance of its duties hereunder and the execution and delivery of this Agreement. All fees owed to
the Escrow Agent pursuant to this Agreement shall be paid for by the Parent.

 

    6

     

    

 

Section
4.Limitation of Escrow Agent’s Liability.

 

4.1 Duties and Limitation of Liability. The Escrow Agent undertakes to perform such duties as are specifically set forth
in this Agreement only and shall have no duty under any other agreement or document, and no implied covenants or obligations shall
be read into this Agreement against the Escrow Agent. The Escrow Agent shall incur no liability with respect to any action taken
by it or for any inaction on its part in reliance upon any notice, direction, instruction, consent, statement or other document
believed by it in good faith to be genuine and duly authorized, nor for any other action or inaction except for its own gross
negligence or willful misconduct. In all questions arising under this Agreement and/or its interpretation hereof in conjunction
with the Business Combination Agreement, the Escrow Agent may rely on the advice of counsel, and for anything done, omitted or
suffered in good faith by the Escrow Agent based upon such advice the Escrow Agent shall not be liable to anyone. In no event
shall the Escrow Agent be liable for incidental, punitive or consequential damages.

  

4.2 Indemnity. Parent will indemnify the Escrow Agent and its officers, directors, employees and agents for, and hold it
and them harmless against, any loss, liability or expense (including attorney fees) incurred by the Escrow Agent without gross
negligence or willful misconduct on the part of the Escrow Agent (or its officers, directors, employees or agents), arising out
of or in connection with the Escrow Agent’s carrying out its duties hereunder excluding any tax imposed on or calculated
by reference to the net income received or receivable by the Escrow Agent. This right of indemnification shall survive the termination
of this Agreement and the resignation of the Escrow Agent.

 

Section
5.Termination. 

 

This
Agreement shall terminate upon the release by the Escrow Agent of all of the Escrow Shares held in the Escrow Account in accordance
with Section 2.

 

Section
6.Successor Escrow Agent. 

 

In
the event the Escrow Agent becomes unavailable or unwilling to continue as escrow agent under this Agreement, the Escrow Agent
may resign and be discharged from its duties and obligations hereunder by giving its written resignation to the Escrow Parties.
In such event, the Escrow Parties may, by mutual agreement, appoint a successor Escrow Agent. If the Escrow Parties fail to appoint
a successor Escrow Agent within thirty (30) calendar days after receiving the Escrow Agent’s written resignation, the Escrow
Agent shall have the right to apply to a court of competent jurisdiction for the appointment of a successor Escrow Agent. The
Escrow Agent’s resignation will take effect upon the appointment of a successor Escrow Agent. The successor Escrow Agent
shall execute and deliver to the Escrow Agent an instrument accepting such appointment, and the successor Escrow Agent shall,
without further action, be vested with all the estates, property rights, powers and duties of the predecessor Escrow Agent as
if originally named as Escrow Agent herein. The Escrow Agent shall act in accordance with written instructions from the Escrow
Parties as to the deposit of the Escrow Shares in the Escrow Account with a successor Escrow Agent.

 

    7

7. Miscellaneous.

 

7.1 Attorneys’
Fees. In any action at law or suit in equity to enforce or interpret this Agreement or the rights of any of the Escrow Parties
or Escrow Agent hereunder (including disputes relating to claims for releases from the Escrow Account), the prevailing Party in

incurred in connection with such action or suit. Notwithstanding the foregoing, neither the HL Representative nor the Company
Shareholder Representative shall have any personal responsibility for any such costs and expenses incurred by him or it in such
representative capacity. The HL Representative and/or the Company Shareholder Representative may make a claim against the Escrow
Account for any costs and expenses incurred by him or it, as applicable.
