captioned &#147;Number of shares offered by this prospectus.&#148; On May&nbsp;10, 2017, the selling stockholders acquired the shares shown in that column directly from us at $40 per share in a private placement exempt from the registration
requirements of the Securities Act of 1933. The private placement involved offers and sales to accredited investors only, without the use of a general solicitation or general advertising. Additional information about the private placement is
contained in our Current Report on Form 8-K filed with the SEC on May&nbsp;10, 2017. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Of the shares shown in the column captioned

Distribution.&#148; We do not know when or in what amounts they will sell their shares. The stockholders could choose not to sell any shares. Although the stockholders identified in the table could choose to sell all, none, or only a portion of the
shares shown in the table, we refer to them in this prospectus as selling stockholders and for purposes of the tabular presentation we are assuming that they will sell all of the shares acquired in the private placement. Each selling stockholder has
requested that all shares acquired in the private placement be registered for resale by this prospectus. None of the selling stockholders has held any position, office, or other material relationship with us at any time during the last three years.

as such generally must be held by the purchaser for at least six months before being resold. However, resales registered with the SEC may be carried out before six months elapse. We therefore agreed when we sold the shares in the private placement
to register the shares for resale by this prospectus. We did not agree to register for resale any other shares owned by any of the stockholders, and none of those other shares may be offered or sold by this prospectus. </P>
