Pursuant to the terms of the Underwriting Agreement, the Company granted the Underwriters a 30-day option to purchase up to an additional 600,000 shares of Series A Preferred Stock. The estimated net proceeds to the Company from this offering after deducting the underwriting discount and other estimated offering costs payable by the Company, will be approximately $96.4 million, or approximately $111.0 million if the Underwriters’ option to purchase additional shares is exercised in full.
