(1) Comprised of shares of common stock issuable upon conversion of shares of the Issuer’s Series A Convertible Preferred Stock (“Series A Convertible Preferred Stock”).

 

(2) The provisions of the Series A Convertible Preferred Stock beneficially owned by the reporting person restrict the conversion of such securities to the extent that, upon such conversion, the number of shares of the Issuer’s common stock then beneficially owned by the holder and its affiliates and any other person or entities with which such holder would constitute a Section 13(d) “group” would exceed 9.985% of the total number of shares of the Issuer’s common stock then outstanding (the “Ownership Cap”). Accordingly, notwithstanding the number of shares reported, the reporting person disclaims beneficial ownership of the shares of common stock issuable upon conversion of such preferred stock to the extent that upon such conversion the number of shares beneficially owned by all reporting persons hereunder, in the aggregate, would exceed the Ownership Cap.

Item 2.Identity and Background.

 

Item 2(e) of the Schedule 13D is hereby amended by adding the following:

 

On August 21, 2017, Deerfield Management voluntarily agreed to settle an SEC administrative proceeding relating to alleged violations of Section 204A of the Investment Advisers Act of 1940 (the “Advisers Act”), without admitting or denying the SEC’s allegations, pursuant to an order under Section 203(e) and 203(k) of the Advisers Act (the “Order”).  The Order resolved the SEC’s allegations that Deerfield Management, from 2012 through 2014, violated Section 204A of the Advisers Act by failing to establish, maintain, and enforce policies and procedures reasonably designed to prevent the misuse of material, nonpublic information, particularly taking into consideration the nature of Deerfield Management’s business.  The Order alleged that, as part of Deerfield Management’s research in the healthcare sector, Deerfield Management engaged third party consultants and research firms, including firms that specialized in providing “political intelligence” regarding upcoming regulatory and legislative decisions, that Deerfield Management employees based certain trading recommendations on such information, and that hedge funds advised by Deerfield Management then made those trades.  The Order required Deerfield Management to cease and desist from committing or causing any violations and any future violations of Section 204A of the Advisers Act, censured Deerfield Management and provided that Deerfield Management will pay disgorgement and interest of $811,695 and a civil money penalty of $3,946,267.
