Item 5. Interest in Securities of the Issuer

As of November 2, 2015, Aella owns of record 1,843,370 Shares (or approximately 12.7% of the total number of Shares of Common Stock of the Issuer currently outstanding). Aella may be deemed to have shared dispositive and voting power with respect to such Shares with The Olive Tree Trust and P. Wilhelm F. Toothe, as trustee of The Olive Tree Trust. Such Shares do not include 1,000 shares of the Issuer's Series B Convertible Preferred Stock, owned of record by Aella, and with respect to which Aella may be deemed to have shared dispositive and voting power with The Olive Tree Trust and with Mr. Toothe, as trustee of The Olive Tree Trust. Such Shares also do not include Shares owned by a third party entity, and which third party entity is owned by a trust of which P. Wilhelm F. Toothe serves as trustee.

The Series B Convertible Preferred Stock ranks (a) with respect to liquidation rights (i) senior to the Shares and (ii) senior to all other classes and series of equity securities of the Issuer that by their terms do not rank senior to the Series B Convertible Preferred Stock, including the Series E Convertible Preferred Stock, and (b) with respect to the payment of dividends (i) on parity with the Shares and the Series E Convertible Preferred Stock of the Issuer and (ii) senior to all other classes and series of equity securities of the Issuer that by their terms do not rank senior to the Series B Convertible Preferred Stock.

Each holder of Series B Convertible Preferred Stock is entitled to receive dividends at the same time any dividends are declared and set apart for payment on any Shares, in an amount which such holder would have been entitled to receive if such Series B Convertible Preferred Stock were converted to Shares (assuming that all outstanding shares of Series B Convertible Preferred Stock are convertible on such date).

Upon the liquidation, dissolution or winding up of the Issuer, prior and in preference to any distribution of any assets or funds of the Issuer to any holder of any series of preferred stock ranking junior to the Series B Convertible Preferred Stock or to any holder of Shares, the holders of the Series B Convertible Preferred Stock shall be entitled to be paid an amount per share equal to $5,000 plus any declared and unpaid dividends on the Series B Convertible Preferred Stock. Any (a) consolidation or merger of the Issuer with or into any other entity or any other reorganization (with certain exceptions), (b) transaction or series of related transactions to which the Issuer is a party in which a majority of the Issuer's voting power is transferred (with certain exceptions) or (c) sale, lease, exclusive license or other disposition of all or substantially all of the assets of the Issuer shall also entitle the holders of the Series B Convertible Preferred Stock to receive the liquidation preference described above.

At any time after December 31, 2015, each share of the Series B Convertible Preferred Stock is convertible at the option of the holder at a conversion price of $4.36. Commencing with December 31, 2016 and thereafter on each of December 31, 2017, December 31, 2018, December 31, 2019 and December 31, 2020, an amount equal to 20% of the shares of Series B Convertible Preferred Stock originally issued to each holder of Series B Convertible Preferred Stock (as that percentage may be adjusted upon certain events) shall automatically be converted into Shares.

Prior to any transfer of any share of Series B Convertible Preferred Stock by any holder, the other holders and the Issuer will have the right, but not the obligation, to purchase such share at a price equal to $5,000 plus any declared but unpaid dividends. In addition, shares of Series B Convertible Preferred Stock may be cancelled for no consideration at the option of the Issuer if the holder breaches certain non-competition obligations.

At any time, at the Issuer's option, shares of the Series B Convertible Preferred Stock may be redeemed at a price per share equal to $5,000 plus any declared but unpaid dividends. The Issuer is not required to redeem the shares of Series B Convertible Preferred Stock proportionately and may at any time redeem shares held by one or any number of holders in any combination. The allocation among the holders of the shares of Series B Convertible Preferred Stock to be redeemed is solely at the discretion of the Issuer.

The shares of Series B Convertible Preferred Stock vote together with the Shares as a single class and each share of Series B Convertible Preferred Stock shall have 1,146 votes.
