SEATTLE, WA–(May 22, 2014) – Atossa Genetics Inc. (NASDAQ: ATOS) today announced that its Board of Directors has approved the adoption of a stockholder rights agreement. The stockholder rights agreement is designed to deter coercive, unfair, or inadequate takeovers and other abusive tactics that might be used in an attempt to gain control of Atossa without paying all stockholders a fair price for their shares. The stockholder rights agreement will not prevent takeovers at a full and fair price, but is designed to deter coercive takeover tactics and to encourage anyone attempting to acquire Atossa to first negotiate with the Board of Directors.

Under the terms of the stockholder rights agreement, the rights agent will distribute to the Company’s stockholders a non-taxable dividend distribution of one preferred stock purchase right for each share of Atossa’s Common Stock held as of the close of business on May 26, 2014. Each right is attached to and trades with the associated share of Common Stock. The rights will become exercisable only if one of the following occurs: (1) a person becomes an “Acquiring Person” by acquiring beneficial ownership of 15% or more of Atossa’s Common Stock, or, in the case of a person who beneficially owned 15% or more of Atossa’s Common Stock on the date the stockholder rights agreement was executed, by acquiring beneficial ownership of additional shares representing 2% (excluding compensatory arrangements) of Atossa’s Common Stock then outstanding, or (2) a person commences a tender offer that, if consummated, would result in such person becoming an Acquiring Person.

If a person becomes an Acquiring Person, each right will entitle the holder, other than the Acquiring Person and certain related parties, to purchase a number of shares of Atossa’s Common Stock with a market value that equals twice the exercise price of the right. The initial exercise price of each right is $15. If Atossa is acquired in a merger or similar business combination transaction at any time after a person has become an Acquiring Person, each holder of a right (other than the Acquiring Person and certain related parties) will be entitled to purchase a similar amount of stock of the acquiring entity.

The rights will expire on May 26, 2024, unless the rights are earlier redeemed or exchanged.

A copy of the stockholder rights agreement will be contained in a Form 8-K to be filed with the Securities and Exchange Commission.
