Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	The 2,664 Class A common units of limited partner interest ("Class A OP Units") in NSA OP, LP (the "Partnership") are issuable upon the conversion of 2,664 long-term incentive plan units ("LTIP Units") in the Partnership. The LTIP Units were granted to the Reporting Person under the Issuer's 2015 Equity Incentive Plan, and are scheduled to vest on May 23, 2018. Vested LTIP Units, after achieving parity with Class A OP Units, are eligible to be converted into Class A OP Units on a one-for-one basis upon the satisfaction of conditions set forth in the Partnership's agreement of limited partnership.
(2)	Upon conversion of such vested parity LTIP Units into Class A OP Units, the Reporting Person will have the right to cause the Partnership to redeem a portion of the Reporting Person's Class A OP Units for cash in an amount equal to the market value of an equivalent number of the Issuer's common shares of beneficial interest ("Shares"), or at the Issuer's option, Shares on a one-for-one basis, subject to certain adjustments.
(3)	N/A
(4)	The price of the derivative securities was determined using the three-day trailing average closing price of the Issuer's Shares on May 24, 2017.
(5)	The Reporting Person's total direct beneficial ownership following the reported transactions above is 100,339 Class A OP Units, which includes those Class A OP Units previously reported and the Class A OP Units reported herein (together with those securities convertible into, or exchangeable for, such Class A OP Units as specified herein and therein). Following the reported transactions, the Reporting Person has total direct beneficial ownership in 3,135 vested LTIP Units and 2,664 unvested LTIP Units. The 100,339 Class A OP Units do not include derivative securities of other classes or non-derivative securities of the Reporting Person that were previously reported.
(6)	Consists of 14,400 vested LTIP Units held by the Reporting Person which were converted into 14,400 Class A OP Units as described in footnote 1 above. The Reporting Person previously reported the 14,400 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, the conversion described in this Form 4 is being reported on a voluntary basis solely to provide notice of the conversion of the Reporting Person's 14,400 LTIP Units into 14,400 Class A OP Units.
