(1)	One year after the date of the completion of the initial public offering of the Issuer, the Reporting Person will have the right to cause NSA OP, LP (the "Partnership") to redeem all or a portion of the Reporting Person's Class A common units of limited partner interest (the "Class A OP Units") for cash in an amount equal to the market value of an equivalent number of the Issuer's common shares, or at the Issuer's option, common shares on a one-for-one basis, subject to certain adjustments.
