Stockholders' Equity

Note 2 — Stockholders’ Equity

Preferred Stock — Our board of directors has the authority, without action by the stockholders, to designate and issue up to 100,000 shares of preferred stock in one or more series and to designate the rights, preferences and privileges of each series, any or all of which may be greater than the rights of our common stock. We have designated 1,000 shares as Series B Preferred Stock (“Series B Preferred”) and 90,000 shares as Series A Junior Participating Preferred Stock (“Series A Preferred”). No shares of Series B Preferred or Series A Preferred are outstanding. In March 2014, we designated 1,200 shares as Series C Convertible Preferred Stock (“Series C Preferred”). In August 2015, we designated 220 shares as Series D Convertible Preferred Stock (“Series D Preferred”).

In August 2015, we entered into a Securities Purchase Agreement with certain investors pursuant to which we sold 220 shares of Series D Preferred, and warrants to purchase up to 3.44 million shares of our common stock at an initial exercise price of $0.40 per share before August 2021, for an aggregate purchase price of $1.1 million. We incurred $0.01 million of stock issuance costs in conjunction with the Series D Preferred, which were netted against the proceeds. The warrants issued in connection with Series D Preferred contain an anti-dilution (“down round”) provision whereby the exercise price per share to purchase common stock covered by these warrants is subject to reduction in the event of certain dilutive stock issuances at any time within two years of the issuance date, but not to be reduced below $0.28 per share. Each share of Series D Preferred has a stated value of $5,000 per share and is convertible into shares of common stock at a conversion price of $0.40 per share. The Series D Preferred is initially convertible into an aggregate of 2,750,000 shares of our common stock, subject to certain limitations and adjustments, has a 5% stated dividend rate, is not redeemable and has voting rights on an as-converted basis.

To account for the issuance of the Series D Preferred and warrants, we first assessed the terms of the warrants and determined that, due to the “down round” provision, they should be recorded as derivative liabilities. We determined the fair value of the warrants on the issuance date and recorded a liability and a discount of $0.6 million on the Series D Preferred resulting from the allocation of proceeds to the warrants. We then determined the effective conversion price of the Series D Preferred which resulted in a beneficial conversion feature of $0.7 million. The beneficial conversion feature was recorded as both a debit and a credit to additional paid-in capital and as a deemed dividend on the Series D Preferred in determining net income applicable to common stock holders in the consolidated statements of operations.

Each share of Series C Preferred has a stated value of $5,000 per share and is convertible into shares of common stock at a conversion price of $0.75 per share. In June 2015, an investor converted 90 shares of Series C Preferred into 0.6 million shares of common stock. In November 2015, an investor converted an additional 90 shares of Series C Preferred into 0.6 million shares of common stock. Also in November 2015, an investor converted 50 shares of Series D Preferred into 0.6 million shares of common stock.

In February 2016, an investor converted 110 shares of Series D Preferred into 1.4 million shares of common stock.

Common Stock — Holders of our common stock are entitled to one vote for each share held of record on all matters submitted to a vote of the holders of our common stock. Subject to the rights of the holders of any class of our capital stock having any preference or priority over our common stock, the holders of our common stock are entitled to receive dividends that are declared by our board of directors out of legally available funds. In the event of our liquidation, dissolution or winding-up, the holders of common stock are entitled to share ratably in our net assets remaining after payment of liabilities, subject to prior rights of preferred stock, if any, then outstanding. Our common stock has no preemptive rights, conversion rights, redemption rights or sinking fund provisions, and there are no dividends in arrears or default. All shares of our common stock have equal distribution, liquidation and voting rights, and have no preferences or exchange rights. Our common stock currently trades on the OTCQB tier of the OTC Markets.

In February 2016, we issued 0.21 million shares with a value of $0.06 million to Novosom as the equity component owed under our December 2015 milestone payment from MiNA Therapeutics. In April 2016, we issued 0.47 million shares with a value of $0.075 million to Novosom as the equity component owed under a March 2016 license agreement covering certain of our platforms for the delivery of an undisclosed genome editing technology. 

Warrants — As noted above, in the Purchase Agreement, we agreed: (x) to extend the termination date of all of the Prior Warrants to February 10, 2020 and (y) to extend the anti-dilution protection afforded of the Prior Warrants so that such protection would apply to any financing transaction effected by us on or prior to June 19, 2017 (with any such adjustment only applying to 80% of the Prior Warrants). In conjunction with this modification, the fair value of the derivative warrant liability associated with the 20% of the Prior Warrants that no longer have the anti-dilution protection equal to $0.09 million was reclassified to additional paid-in capital.

As of June 30, 2016, there were 24,466,783 warrants outstanding, with a weighted average exercise price of $0.47 per share, and annual expirations as follows:

Expiring in 2016	-
Expiring in 2017		2,630,545
Expiring in 2018		113,831
Expiring thereafter		21,722,407
