#### MAJORITY VOTE AND TRUSTEE RESIGNATION POLICY
We have a majority voting policy for the election of trustees in uncontested elections. Under majority voting, to be elected as a trustee in an uncontested election, a nominee must receive votes "FOR" the nominee's election constituting a majority of the total votes cast for and against such nominee at the annual meeting at which a quorum is present. If an incumbent trustee does not receive sufficient "FOR" votes to be re-elected, Maryland law provides that the incumbent trustee would continue to serve on the Board as a "holdover" trustee. Under the Guidelines, the trustee must submit a letter of resignation to the Board. The CNCG Committee will consider such tendered resignation and recommend to the Board whether to accept it. The Board will decide whether to accept any such resignation within 90 days after certification of the election results and will publicly disclose its decision. If the resignation is not accepted, the trustee will continue to serve until the trustee's successor is duly elected and qualifies or until the trustee’s earlier death, resignation, retirement or removal. If a trustee’s offer to resign is accepted by the Board, or if a nominee for trustee is not elected and the nominee is not an incumbent trustee, then the Board, in its sole discretion, may fill any resulting vacancy pursuant to the Bylaws. In a contested election, trustees shall be elected by a plurality of all the votes cast at a meeting of shareholders duly called and at which a quorum is present.

#### BYLAW AMENDMENTS
We have a policy to permit equity holders to alter or repeal any provision of the Bylaws and to adopt new Bylaws. Approval of amendments to the Bylaws by equity holders requires the affirmative vote of both:

• holders of a majority of the Company's Common Shares outstanding as of the Determination Date (as defined below); and

• holders of Common Shares and limited partners (other than the Company) of our operating partnership, NSA OP, LP (our "operating partnership"), representing a majority of the number of Common Shares outstanding as of the Determination Date together with the number of additional Common Shares that would be issuable if all Class A common units of limited partner interest ("OP units") in our operating partnership outstanding as of the Determination Date were exchanged on a one-for-one basis, subject to adjustments as provided in the Fourth
