Ladies and Gentlemen:

We have acted as counsel to Reinvent Technology Partners Z, a Cayman Islands exempted company (“RTPZ” and, after the Domestication as defined below, “Hippo Holdings”), in connection with the proposed (1) domestication of RTPZ as a Delaware corporation (the “Domestication”) and (2) the merger of RTPZ Merger Sub Inc., a Delaware corporation and a direct wholly owned subsidiary of RTPZ (“Merger Sub”), with and into Hippo Enterprises Inc., a Delaware corporation (“Hippo”) (the “First Merger”), with Hippo surviving the Merger as a wholly owned subsidiary of Hippo Holdings, and, immediately following the First Merger, the merger of Hippo (as the surviving corporation of the First Merger) with and into Hippo Holdings, with Hippo Holdings surviving (the “Second Merger” and, together with the First Merger, the “Mergers”), in each case pursuant to the terms of the Agreement and Plan of Merger, dated as of March 3, 2021, by and among RTPZ, Merger Sub and Hippo (the “Merger Agreement”). Reference is made herein to the Form S-4 filed by RTPZ on [March 25], 2021 with the Securities and Exchange Commission in connection with the Mergers (including the proxy statement/prospectus forming a part thereof, as amended or supplemented through the date hereof, the “Registration Statement”).

statements and representations we have neither investigated nor verified) made by RTPZ in its officer’s certificate dated as of the date hereof and delivered to us for purposes of this opinion (the “Officer’s Certificate”) is true, complete and correct as of the date hereof and will remain true, complete and correct at all times up to and including the date of the Domestication and thereafter (where relevant) without regard to any qualification as to knowledge, intention or belief, and (v) RTPZ (and Hippo Holdings after the Domestication) will treat the Domestication for United States federal income tax purposes in a manner consistent with the opinion set forth below. If any of the above described assumptions is untrue for any reason or if the Domestication or related transaction is consummated in a manner that is di
