Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 5(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) This amendment is being filed because the number of shares reported in the reporting person's original Form 3 did not reflect shares issued pursuant to a 1.6525 to 1 forward stock split on July 21, 2014. As of the date of the original Form 3, the reporting person holds an aggregate of 500,704 shares of Series A-I Convertible Preferred Stock which are convertible into 1,609,560 shares of common stock of the issuer upon the consummation of the issuer's initial public offering pursuant to an effective registration statement on Form S-1. The convertible securities convert automatically upon such event and have no expiration date or conversion price.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, See Instruction 6 for procedure.

Potential persons who are to respond to the collection of information contained in this form are not required to respond unless the form displays a currently valid OMB number.
