  3.    Stamp Duty. A new section 5.7 is hereby inserted into the Warrant
Agreement as follows: 
 “5.7 Stamp Duty. Notwithstanding the provisions prejudice to Section 5.1, Irish Holdco may require,
as a condition to the registration of any transfer of a Warrant, evidence from the transferor or intended transferee, which is satisfactory to the Company, that any Irish stamp duty liability arising on such transfer has been duly paid (and any
instrument of transfer, as the case may be, has been duly stamped for Irish stamp duty purposes) or that the proposed transfer is otherwise exempt from such duty. The Company, at its absolute discretion, may, or may procure that one of its
subsidiaries shall, pay any Irish stamp duty arising on a transfer of Warrants on behalf of the transferee of such Warrants. If stamp duty resulting from the transfer of Warrants in the Company which would otherwise be payable by the transferee is
paid by the Company or any subsidiary of the Company on behalf of the transferee, then in those circumstances, the Company shall, on its behalf 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 the stamp duty against any dividends payable by the Company to the transferee of those Warrants and (iii) to the extent permitted by section 1042 of the
Companies Act 2014 of Ireland, as amended, and every statutory modification and re-enactment thereof for the time being, claim a first and paramount lien on the Warrants (or Company Ordinary Shares issued upon
the exercise of Warrants) on which stamp duty has been paid by the Company or its subsidiary for the amount of stamp duty paid. The Company’s lien shall extend to all dividends paid on Company Ordinary Shares issued upon the exercise of such
Warrants.” 
 4.    Effectiveness. Notwithstanding anything to the contrary contained herein, this Amendment
shall only become effective upon the Closing. In the event that the Business Combination Agreement is terminated in accordance with its terms prior to the Closing, this Amendment and all rights and obligations of the parties hereunder shall
automatically terminate and be of no further force or effect. 

  
 3 














 5.    Miscellaneous. Except as expressly provided in this
Amendment, all of the terms and provisions in the Warrant Agreement are and shall remain in full force and effect, on the terms and subject to the conditions set forth therein. This Amendment does not constitute, directly or by implication, an
amendment or waiver of any provision of the Warrant Agreement, or any other right, remedy, power or privilege of any party thereto, except as expressly set forth herein. Any reference to the Warrant Agreement in the Warrant Agreement or any other
agreement, document, instrument or certificate entered into or issued in connection therewith, shall hereinafter mean the Warrant Agreement as the case may be, as amended by this Amendment (or as such agreement may be further amended or modified in
accordance with the terms thereof). The terms of this Amendment shall be governed by, enforced and construed and interpreted in a manner consistent with the provisions of the Warrant Agreement, as it applies to the amendments to the Warrant
Agreement herein, including without limitation Section 9 of the Warrant Agreement.
