Item 4.

Ownership:

Amount Beneficially Owned:

As of January 31, 2017, Nantahala is no longer a beneficial owner of Shares of the Issuer. As of December 31, 2016, Nantahala may have been deemed to have been the beneficial owner of 2,917,904 Shares, which included 2,010,970 Shares and 906,934 Shares issuable upon the conversion of the Issuer's 8.50% Senior Unsecured Convertible Notes due 2019 held by funds and separately managed accounts under its control, and as the managing members of Nantahala, each of Messrs. Harkey and Mack may have been deemed to be a beneficial owner of those Shares. Funds and separately managed accounts advised by Nantahala held $9,970,000 in aggregate principal amount of the Issuer’s 8.50% Notes as of December 31, 2016. Such 8.50% Notes are subject to a conversion limitation imposed by Florida State law that voids any conversion of such 8.50% Notes into Shares to the extent that the holder would, after such exercise, directly or indirectly own 10% or more of the Shares outstanding unless such holder has first applied for and obtained regulatory approval from the Florida Office of Insurance Regulation. The Reporting Persons had not sought, and had no intention to seek, such approval, and thus, considering the Reporting Persons’ other beneficial ownership of Shares, as of December 31, 2016, the Reporting Persons could have converted such 8.50% Notes for no more than 906,934 Shares. If freely convertible in their entirety, the 8.50% Notes beneficially owned by the Reporting Persons would have been convertible for 1,513,356 Shares.

Percent of Class:

As of January 31, 2017, Nantahala is a beneficial owner of 0.0% of the total number of Shares outstanding. As of December 31, 2016, the Reporting Persons may have been deemed to be the beneficial owner of 9.9% of the total number of Shares outstanding (based upon information provided by the Issuer on Form 10-Q filed November 7, 2016, there were 28,272,211 Shares outstanding as of November 4, 2016 in addition to the 906,934 Shares issuable upon the conversion of the Issuer's 8.50% Senior Unsecured Convertible Notes due 2019 for which the Reporting Person had made voting and investment decisions which are not subject to a conversion limitation imposed by Florida State Law).

Each of Messrs. Harkey and Mack:

As of January 31, 2017 Nantahala is no longer a beneficial owner of Shares. Notwithstanding, Nantahala continues to hold $15,470,000 in aggregate principal amount of the Issuer's 8.50% Senior Unsecured Convertible Notes due 2019 which would potentially be convertible to Shares but cannot currently or within 60 days be exercised to acquire shares pursuant to a contractual agreement with the Issuer.
