On April 3, 2013, the BOD approved a 2013 Stock Option Grant totaling 10,305,000 options, available in part to all eligible employees of the Company, that vests only with the achievement of certain pre-determined milestones relating to commercialization of CytoSorb&amp;reg;, financing, business development, and product development. &lt;font style="COLOR: #010202"&gt;Due to the uncertainty over whether approximately 9,455,000 of the 10,305,000 options granted will vest, no charge for these options has been recorded in the consolidated statements of operations for the six months ended June 30, 2013. The grant date fair value of these unvested options amounts to approximately $284,000.&lt;/font&gt; The Company will evaluate on an ongoing basis the probability and likelihood of any of these performance milestones being achieved and will accrue charges as it becomes likely that they will be achieved.&lt;/p&gt; &lt;p style="FONT: 10pt Times New Roman, Times, Serif; MARGIN: 0pt 0px"&gt; &amp;nbsp;&lt;/p&gt; &lt;p style="FONT: 10pt Times New Roman, Times, Serif; MARGIN: 0pt 0px"&gt; In addition, a pool of 22,750,000 shares of restricted stock was allocated, but not awarded, to only be awarded with the achievement of certain long-term milestones. Should these long-term milestones not be met in 2013, these restricted shares would be cancelled.&lt;/p&gt; &lt;p style="FONT: 10pt Times New Roman, Times, Serif; MARGIN: 0pt 0px"&gt; &amp;nbsp;&lt;/p&gt;

The Company can also accelerate the amount of its common stock to be purchased under certain circumstances. No sales of shares may occur at a purchase price below $0.10 per share or without a registration statement having been declared effective. The purchase price of the shares will be based on the market prices of our shares at the time of sale as computed under the New Purchase Agreement without any fixed discount.
