Item 4.     Ownership



	The information required by Items 4(a) - (c) is set forth in Rows (5)-
(11) of the cover page for each Reporting Person hereto and is incorporated
herein by reference for each such Reporting Person.

The Company's Amendment No. 6 to the Registration Statement on Form S-1/A filed
with the Securities and Exchange Commission on December 7, 2015, discloses the
total number of outstanding shares of Common Stock as of December 3, 2015 was
2,464,160. The percentage set forth on Row (11) and the number of shares of
Common Stock set forth on rows (6), (8) and (9) of the cover page for each
Reporting Person are based on the Company's total number of outstanding shares
of Common Stock and assume the conversion of  convertible notes and the
exercise of warrants (collectively, the "Securities"), subject to the 9.99%
Blockers (as defined below) or the 4.99% Blockers (as defined below), as
applicable.

Pursuant to the terms of certain of the Securities, the Reporting Persons cannot
convert or exercise such Securities if the Reporting Persons would beneficially
own, after such conversion or exercise, more than 9.99% of the outstanding
shares of Common Stock (the "9.99% Blockers"). Pursuant to the terms of certain
other Securities, the Reporting Persons cannot exercise such other Securities if
the Reporting Persons would beneficially own, after such exercise, more than
4.99% of the outstanding shares of Common Stock (the "4.99% Blockers" and
together with the 9.99% Blocker, the "Blockers"). The percentage set forth on
Row (11) and the number of shares of Common Stock set forth on rows (6), (8)
and (9) of the cover page for each Reporting Person give effect to the Blockers.
Consequently, at this time, the Reporting Persons are not able to convert all of
such Securities due to the Blockers.

The Investment Manager, which serves as the investment manager to Hudson Bay
Master Fund Ltd., in whose name the securities reported herein are held, may be
deemed to be the beneficial owner of all shares of Common Stock held by Hudson
Bay Master Fund Ltd. and all shares of Common Stock, subject to the applicable
Blocker, underlying the Securities held by Hudson Bay Master Fund Ltd.  Mr.
Gerber serves as the managing member of Hudson Bay Capital GP LLC, which is the
general partner of the Investment Manager.  Mr. Gerber disclaims beneficial
ownership of these securities.

Item 5.     Ownership of Five Percent or Less of a Class

      Not applicable.

Item 6.     Ownership of More than Five Percent on Behalf of Another Person

      See Item 4.

Item  7.    Identification and Classification of the Subsidiary Which Acquired
            the Security Being Reported on by the Parent Holding Company

      Not applicable.

Item 8.     Identification and Classification of Members of the Group

      Not applicable.

Item 9.     Notice of Dissolution of Group

      Not applicable.

Item 10.    Certification

By signing below each Reporting Person certifies that, to the best of his or
its knowledge and belief, the securities referred to above were acquired and
are held in the ordinary course of business and were not acquired and are not
held for the purpose of or with the effect of changing or influencing the

in connection with or as a participant in any transaction having that purpose
or effect.
