Item 1.01    Entry into a Material Definitive Agreement.

On May5, 2010, Cytosorbents Corporation  (the “Company”) signed a purchase agreement with Lincoln Park Capital Fund, LLC (“LPC”), an Illinois limited liability company, together with a registration rights agreement, whereby LPC has agreed to purchase up to $6 million of our common stock over a 25-month period (the “Purchase Agreement” and “Registration Rights Agreement”, respectively).  Under the Registration Rights Agreement, the Company agreed to file a registration statement related to the transaction with the U.S. Securities & Exchange Commission (“SEC”) covering the shares that may be issued to LPC under the Purchase Agreement.  After the SEC has declared effective the registration statement related to the transaction, the Company will have the right over a 25-month period to sell our shares of common stock to LPC in amounts between $50,000 and $750,000, depending on certain conditions as set forth in the purchase agreement, for up to $6 million.

The purchase price of the shares related to the future funding will be based on the prevailing market prices of the Company’s shares at the time of sales without any fixed discount, and the Company will control the timing and amount of any sales of shares to LPC.  LPC shall not have the right or the obligation to purchase any shares of our common stock on any business day that the price of our common stock is below $0.10.

In consideration for entering into the $6 million Purchase Agreement, we issued to LPC 1,153,846 shares of our common stock as a commitment fee and shall issue an equivalent amount of shares pro rata as LPC purchases the $6 million.  The common stock purchase agreement may be terminated by us at any time at our discretion without any cost to us.  There are no negative covenants, restrictions on future fundings, penalties or liquidated damages in the agreement.  The proceeds received by the Company under the common stock purchase agreement will be used to complete the European Sepsis Trial, pursue CE Mark approval and commercialization of CytoSorb™, expand its product pipeline and for general working capital purposes.

The foregoing description of the Purchase Agreement and the Registration Rights Agreement are qualified in their entirety by reference to the full text of the common stock purchase agreement and the registration rights agreement, a copy of each of which is attached hereto as Exhibit 10.1 and 10.2, respectively, and each of which is incorporated herein in its entirety by reference.
