 NOW, THEREFORE, in consideration of
the mutual agreements contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the parties hereto agree as follows: 

1 Amendment of Existing Warrant Agreement. The parties hereby amend, effective as of the date of this Agreement, the Existing Warrant

 Any notice, statement or demand authorized by this Agreement to be given or made by the
holder of any Warrant or by the Company to or on the Warrant Agent shall be sufficiently given when so delivered if by hand or overnight delivery or if sent by certified mail or private courier service within five (5) days after deposit of such

 1.3 Cashless Exercise at Company’s Option. Section 7.4.2 of the Existing Warrant Agreement is
hereby amended and restated in its entirety to read as follows: 
 If the Ordinary Shares are at the time of any exercise of a Public Warrant
not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, (i) require holders of Public Warrants who
exercise Public Warrants to exercise such Public Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act as described in subsection 7.4.1 and (ii) in the event the Company so elects,
the Company shall (x) not be required to file or maintain in effect a registration statement for the registration, under the Securities Act, of the Ordinary Shares issuable upon exercise of the Warrants, notwithstanding anything in this
Agreement to the contrary, and (y) use its commercially reasonable efforts to register or qualify for sale the Ordinary Shares issuable upon exercise of the Public Warrant under applicable blue sky laws to the extent an exemption is not
available. Upon receipt of a Cashless Exercise the Warrant Agent will provide to the company for calculation. After the calculation the company will provide the Warrant Agent with the issuance instructions for new common shares. 

2 Warrant Agent Succession and Resignation of Current Warrant Agent and Appointment of Successor. Continental hereby resigns as Warrant Agent,
and Aurora hereby appoints AST to act as the Warrant Agent for Aurora for the Warrants, and AST hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in the Existing Warrant Agreement as
modified by this Agreement. 
 3 Miscellaneous Provisions. 

3.1 Successors. All the covenants and provisions of this Agreement by or for the benefit of the parties shall bind and inure to the
benefit of their respective successors and assigns. 
 3.2 Applicable Law. The validity, interpretation, and performance of this
Agreement and of the Warrants shall be governed in all respects by the laws of the State of New York, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. Aurora
hereby agrees that any action, proceeding or claim against it arising out of or relating in any way to this Agreement shall be brought and enforced in the courts of the State of New York or the United States District Court for the Southern District
of New York, and irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive. Aroura hereby waives any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum.

 3.3 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. 

3.4 Effect of Headings. The section headings herein are for convenience only and are not part of this Agreement and shall not affect the
interpretation thereof. 
 3.5 Severability. This Agreement shall be deemed severable, and the invalidity or unenforceability of any
term or provision hereof shall not affect the validity or enforceability of this Agreement or of any other term or provision hereof. Furthermore, in lieu of any such invalid or unenforceable term or provision, the parties hereto intend that there
shall be added as a part of this Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible and be valid and enforceable. 

3.6 Entire Agreement. The Existing Warrant Agreement, as modified by this Agreement, constitutes the entire understanding of the
parties and supersedes all prior agreements, understandings, arrangements, promises and commitments, whether written or oral, express or implied, relating to the subject matter hereof, and all such prior agreements, understandings, arrangements,
promises and commitments are hereby canceled and terminated.
