Item 5.    Interest in Securities of the Issuer.

 
(a)
The Fund is the record owner of 2,752,488 shares of the Issuer's Common Stock (the "Clarus Shares").  As the sole general partner of the Fund, Clarus GP may be deemed to own beneficially the Clarus Shares.  As the sole general partner of Clarus GP, Clarus GPLLC may be deemed to own beneficially the Clarus Shares.  As members of Clarus GPLLC, each of the Managing Directors may be deemed to own beneficially the Clarus Shares.

As of September 23, 2016, Mr. Galakatos is the record owner of options to purchase 5,187 shares of the Issuer's Common Stock (the "Options").  The Options may be exercised as of the date hereof and/or within 60 days of the date hereof.  Accordingly, Mr. Galakatos may be deemed to own beneficially the Options and Clarus Shares.
Each Reporting Person disclaims beneficial ownership of the Clarus Shares other than those shares which such person owns of record.

The percentage of outstanding Common Stock of the Issuer which may be deemed to be beneficially owned by each Reporting Person is set forth on Line 13 of such Reporting Person's cover sheet and was calculated based on (1) the 15,381,418 shares of Common Stock reported to be outstanding as of July 31, 2016 on the Issuer's Form 10-Q filed with the Securities Exchange Commission on August 11, 2016 (the "10-Q"), plus (2) the 2,500,000 shares of Common Stock reported to be outstanding as of September 22, 2016 on the Issuer's Form 8-K filed with the Securities Exchange Commission on September 23, 2016 (the "8-K" and, together with the 10-Q, the "Public Filings"), plus (3) solely with respect to Line 13 of Mr. Galakatos' cover sheet, the Options.  The percentage of outstanding Common Stock of the Issuer which was deemed to be beneficially owned by each Reporting Person, as of the date of the event that triggered this filing is set forth on Line 13 of such Reporting Person's cover sheet and is based upon 17,881,418 shares of Common Stock outstanding as indicated in the Public Filings.

(b) Regarding the number of shares as to which such person has:

(i) sole power to vote or to direct the vote: See line 7 of cover sheets

(ii) shared power to vote or to direct the vote: See line 8 of cover sheets

(iii) sole power to dispose or to direct the disposition: See line 9 of cover sheets.

(iv) shared power to dispose or to direct the disposition: See line 10 of cover sheets

(c) None of the Reporting Persons has effected any transaction in the Common Stock during the last 60 days.

(d) No other person is known to have the right to receive or the power to direct the receipt of dividends from, or any proceeds from the sale of, securities beneficially owned by any of the Reporting Persons.
