 underwriting agreement if any of these shares are purchased, other than shares covered by the underwriters’ option to purchase additional shares described below. The underwriters are offering the shares, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by counsel to the underwriters and other conditions specified in the underwriting agreement. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part. We have granted to the underwriters an option to purchase up to 2,433,000 additional shares of our common stock at the public offering price set forth on the cover page of this prospectus supplement, less the underwriting discount. The underwriters may exercise this option, in whole or in part, for up to 30 days from the date of this prospectus supplement. If the underwriters exercise this option, each underwriter will be obligated, subject to the conditions in the underwriting agreement, to purchase a number of additional shares of common stock from us in approximately the same proportion as set forth in the table above. Underwriting Discount The underwriters propose to offer shares of our common stock directly to the public at the price set forth on the cover page of this prospectus supplement and to selected dealers, which may include the underwriters, at such offering price less a selling concession not in excess of $0.9250 per share. If all of the shares of our common stock are not sold at the public offering price, the representatives of the underwriters may change the public offering price and the other selling terms. The following table shows the public offering price, underwriting discount and proceeds to us, before expenses, on both a per share and aggregate basis. The aggregate amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares of our common stock, and assuming no participation in the directed share program for purposes of the underwriting discounts and commissions.
