(1)	The Reporting Person redeemed 21,750 Class A common units of limited partner interest (the "Class A OP Units") of NSA OP, LP (the "Partnership"), of which National Storage Affiliates Trust (the "Issuer") is the general parter. These Class A OP Units were held by The Tricia Van Mourick Separate Property Trust U/A dated 03/29/2012, which received 21,750 common shares of beneficial interest ("Shares") of the Issuer upon redemption. The Shares are held in a trust for the benefit of the Reporting Person's spouse and children. The Reporting Person's spouse is trustee of the trust.
(2)	This filing shall not be deemed to be an admission that the Reporting Person is the beneficial owner of any of the securities reported herein, and the Reporting Person disclaims beneficial ownership of such securities except to the extent of the Reporting Person's pecuniary interest therein.
(3)	The Reporting Person's total direct and indirect beneficial ownership following the reported transactions above is (i) 0 Shares, and (ii) 107,275 Class A OP Units (which includes those securities convertible into, or exchangeable for, such Class A OP Units as previously reported). As of November 21, 2016, in connection with a corporate reorganization, the Reporting Person was no longer a controlling person and did not have or share voting or investment power over the portfolio of Optivest Properties, LLC ("Optivest").
