Pursuant to the Underwriting Agreement, the Company agreed to sell to the Underwriters, and the Underwriters agreed to purchase from the Company, an aggregate of 6,428,571 shares of common stock and also granted the Underwriters a 30 day option to purchase up to 964,285 additional shares of its common stock to cover over-allotments, if any.
