We, as your counsel, have examined originals or copies of such documents, corporate records, certificates of public officials and other instruments as we have deemed necessary or advisable for the purpose of rendering this opinion.

 

In rendering the opinions expressed herein, we have, without independent inquiry or investigation, assumed that (i) all documents submitted to us as originals are authentic and complete, (ii) all documents submitted to us as copies conform to authentic, complete originals, (iii) all documents filed as exhibits to the Registration Statement that have not been executed will conform to the forms thereof, (iv) all signatures on all documents that we reviewed are genuine, (v) all natural persons executing documents had and have the legal capacity to do so, (vi) all statements in certificates of public officials and officers of Equinix, Equinix Europe 2 Finco, Equinix Canada Finco and Equinix Singapore Finco that we reviewed were and are accurate and (vii) all representations made by Equinix, Equinix Europe 2 Finco, Equinix Canada Finco and Equinix Singapore Finco as to matters of fact in the documents that we reviewed were and are accurate.

 

Based upon the foregoing, and subject to the additional assumptions and qualifications set forth below, we advise you that, in our opinion:
