USE OF PROCEEDS

We will retain broad discretion over the use of the net proceeds to us from the sale of our securities under this prospectus. Unless otherwise
provided in the applicable prospectus supplement, we currently expect to use the net proceeds that we receive from any offerings for working capital and other general corporate purposes. We cannot specify with certainty all of the particular uses
for the net proceeds to be received upon the closing of any offerings. Pending these uses, we may invest the net proceeds of any offering in short- and intermediate-term, interest-bearing obligations, investment-grade instruments, certificates of
deposit or direct or guaranteed obligations of the U.S. government.

We will not receive any of the proceeds from the sale of our
securities by the selling stockholders.

SELLING STOCKHOLDERS

This prospectus also relates to the possible resale by certain of our stockholders, who we refer to in this prospectus as the “selling
stockholders,” of shares of our common stock that were issued and outstanding prior to the original date of filing of the registration statement of which this prospectus forms a part. Information about any selling stockholders, where
applicable, including their identities and the number of shares of common stock to be registered on their behalf, will be set forth in a prospectus supplement, in a post-effective amendment, or in filings we make with the SEC under the Exchange Act
that are incorporated by reference. The selling stockholders shall not sell any shares of our common stock pursuant to this prospectus until we have identified such selling stockholders and the shares being offered for resale by such selling
stockholders. However, the selling stockholders may sell or transfer all or a portion of their shares of our common stock pursuant to any available exemption from the registration requirements of the Securities Act.
