On January 12, 2011, Cell Therapeutics, Inc. (the “Company”) entered into a Securities Purchase Agreement (the “Purchase Agreement”) between the Company and Socius CG II, Ltd. Pursuant to the Purchase Agreement, the Company agreed to issue to the Socius CG II, Ltd. in a registered offering (i) up to 25,000 shares of the Company’s Series 8 Non-Convertible Preferred Stock, no par value per share (the “Series 8 Preferred Stock”), (ii) warrants (the “Warrants”) to purchase up to 22,563,177 shares of the Company’s common stock, no par value per share, and (iii) an additional investment right (the “Additional Investment Right”) to purchase up to 25,000 shares of the Company’s Series 9 Convertible Preferred Stock, no par value per share (the “Series 9 Preferred Stock”), for an aggregate offering price of $25 million (the “Offering”). The closing of the Offering is subject to certain conditions.

The shares of Series 8 Preferred Stock will accrue annual dividends at the rate of 10% from the date of issuance, payable in additional shares of Series 8 Preferred Stock. The shares of Series 8 Preferred Stock are redeemable at the option of the Company at any time after issuance, in whole or in part, either in cash or by offset against recourse notes fully secured with marketable securities (“Notes”), which may be issued by Socius CG II, Ltd. to the Company in connection with the exercise of the Warrants and the Additional Investment Right.

Each Warrant has an initial exercise price of $0.3878 per share of common stock. The Warrants are exercisable immediately and expire two years from the date of issuance, provided that the Warrants must be exercised simultaneously with the exercise of the Additional Investment Right so that the percentage of the Warrants that have been exercised will always equal or exceed the percentage of the Additional Investment Right that has been exercised. The exercise price for the Warrants may be paid in cash or through the issuance by Socius CG II, Ltd. to the Company of Notes. The Warrants are subject to mandatory exercise and cancellation, in whole or in part, in certain circumstances.

The Additional Investment Right has an exercise price of $1,000 per share of Series 9 Preferred Stock. The Additional Investment Right is exercisable immediately and must be exercised no later than February 11, 2011. The exercise price of the Additional Investment Right may be paid in cash or through the issuance of Notes by Socius CG II, Ltd to the Company. The Additional Investment Right is subject to cancellation, in whole or in part, in certain circumstances.

Each share of Series 9 Preferred Stock is convertible at the option of the holder, at any time during its existence, into approximately 2,579 shares of common stock at a conversion price of $0.3878 per share of common stock, for a total of approximately 64,466,219 shares of common stock.
 
See the Current Report on Form 8-K filed by the Company on January 18, 2011 for more details on the Offering.
