WHEREAS, the Purchaser desires to purchase in the Offering, upon the terms and conditions set forth in this Agreement, up to that minimum number of shares of Common Stock required for the Purchaser to retain its pro rata ownership of the outstanding shares of the Common Stock of the Company immediately following the closing of the Offering (the “Initial Pro Rata Shares”), based upon the public offering price per share of Common Stock in the Offering and subject to the limitations described herein; and
