Stockholder Rights Plan On June 8, 2010, the Board of Directors of the Company approved a stockholder rights plan and declared a dividend distribution of one Right for each outstanding share of Common Stock of the Company. Each Right entitles the holder to purchase from the Company a unit consisting of one one-hundredth of a share (a “Unit”) of the Series A Junior Participating Preferred Shares of the Company. The dividend was declared on June 8, 2010 (the "Rights Dividend Declaration Date") to stockholders of record as of the close of business on June 21, 2010 (the “Record Date”).

- Definition

Tabular disclosure of warrants or rights issued. Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.
