12.	SHAREHOLDERS' EQUITY:

Preferred Stock

The Company’s Articles of Incorporation authorize it to issue up to 5,000,000 shares of preferred stock with designations, rights and preferences determined from time-to-time by the Company’s Board of Directors. Accordingly, the Company’s Board of Directors is empowered, without shareholder approval, to issue preferred stock with dividend, liquidation, conversion, voting or other rights superior to those of shareholders of the Company’s common stock.

In 1995, the Company issued 200,000 shares of Series A Nonconvertible Preferred Stock (Series A) to American Biomimetics Corporation (ABC) pursuant to a certain Technology Transfer Agreement between the Company and ABC. The Series A shares have a liquidation value of $7.50 per share. Series A shareholders, as a single class, have the right to elect two members of the Company’s Board of Directors. This right has never been exercised. Holders of the Series A shares are entitled to one vote per share on matters which shareholders are generally entitled to vote. The Series A shareholders are not entitled to any dividends.

As of December 31, 2016, the Company had issued 200,000 shares of preferred stock, all of which were outstanding.

Common Stock

The Company is authorized to issue 100,000,000 shares of $0.01 par value common stock. Each share of the Company’s common stock entitles the holder to one vote on all matters to be voted upon by the shareholders. As of December 31, 2016, the Company had issued 48,270,990 shares of common stock of which 46,913,127 were outstanding.
