(1) Pursuant to the agreement of limited partnership of NSA OP, LP (the "Partnership"), upon the achievement of certain conditions, a holder of long-term incentive plan units ("LTIP Units") of the Partnership is entitled to convert such LTIP Units into Class A common units of limited partner interest ("Class A OP Units") of the Partnership on a one-for-one basis. In addition, under the Partnership agreement, the Reporting Person has the right to cause the Partnership to redeem all or a portion of the Reporting Person's resulting Class A OP Units for cash in an amount equal to the market value of an equivalent number of the common shares of beneficial interest ("Shares") of National Storage Affiliates Trust (the "Issuer"), or at the Issuer's option, Shares on a one-for-one basis, subject to certain adjustments.

(3) N/A
(4) Following the reported transactions, the Reporting Person has total direct beneficial ownership in 5,887 vested LTIP Units and 39,511 unvested LTIP Units. The Reporting Person previously reported the 24,000 LTIP Units that were converted into Class A OP Units as described in this Form 4 as Class A OP Units on an as-converted basis. Accordingly, this Form 4 is being filed on a voluntary basis solely to provide notice of the conversion of the Reporting Person's 24,000 LTIP Units into 24,000 Class A OP Units.
