### ABOUT THIS PROSPECTUS
This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission, or the “SEC,” utilizing a “shelf” registration process. Under this shelf registration process, we may from time to time offer and sell the securities described in this prospectus in one or more offerings, up to a total initial aggregate offering price for all offerings of $150,000,000. This prospectus provides you with a general description of the securities we may offer. Each time these securities are offered, we will provide a prospectus supplement that will contain specific information about the terms of the offering and include a discussion of any risk factors or other special considerations that apply to the securities and the offering. The prospectus supplement may also add, update or change information contained in this prospectus. You should read this prospectus, the applicable prospectus supplement and any pricing supplement together with the additional information described under the heading “Where You Can Find More Information.”
