We have granted a 45-day option to the representative of the underwriters to purchase additional shares of common stock up to an additional 571,428 shares to be offered by us solely to cover over-allotments, if any. If the underwriters exercise their right to purchase additional shares of common stock to cover over-allotment, we estimate that we will receive gross proceeds of $35,047,608 from the sale of 4,380,951 shares of common stock being offered at an assumed public offering price of $8.00 per share and net proceeds of $32,944,752 after deducting $2,102,856 for underwriting discounts and commissions. The shares issuable upon exercise of the underwriter option are identical to those offered by this prospectus and have been registered under the registration statement of which this prospectus forms a part.
