 this offering payable by us, excluding any commissions and expense reimbursement payable to the
Managers under the equity distribution agreement, including amounts paid through the date of this prospectus supplement, will be approximately $750,000, and we expect to incur additional expenses (in addition to any such commissions and expense
reimbursement) in connection with this offering in the future. We have agreed to reimburse each of the Managers, the Forward Sellers and the Forward Purchasers for certain of their legal expenses in certain circumstances in connection with the
equity distribution agreement.

In connection with the sale of shares of our common stock, each of the Managers, Forward Sellers or
Forward Purchasers may be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation paid to the Managers, the Forward Sellers or the Forward Purchasers may be deemed to be underwriting commissions or
discounts. We have agreed in the equity distribution agreement to provide indemnification and contribution to each of the Managers, Forward Sellers and Forward Purchasers against certain civil liabilities, including liabilities under the Securities
Act.

Sales of shares of our common stock as contemplated by this prospectus supplement will be settled through the facilities of The
Depository Trust Company or by such other means as we and the applicable Manager or Forward Seller may agree upon.

The offer and sale of
shares of our common stock pursuant to the equity distribution agreement will terminate upon the earliest of (1) the sale of the maximum aggregate amount of shares of our common stock subject to the equity distribution agreement; and
(2) the termination of the equity distribution agreement by either us at any time with written notice or a Manager, Forward Seller or Forward Purchaser with respect to its respective obligations under the equity distribution agreement, at any
time upon written notice.

Shares of our common stock are “actively-traded securities” excepted from the requirements of Rule
101 of Regulation M under the Exchange Act. If we have reason to believe that the exemptive provisions set forth in

S-16

Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied, we will promptly notify the Managers, the Forward Sellers and the Forward Purchasers and sales of shares of our common
stock under the equity distribution agreement will be suspended until that or other exemptive provisions have been satisfied in the judgment of the Managers, the Forward Sellers, the Forward Purchasers and us.
