Released: 06/23/11 10:21 AM EDT
Strengthens Ability to Accelerate CBLB502 Development

BUFFALO, NY -- (Marketwire) -- 06/23/11 -- Cleveland BioLabs, Inc. (NASDAQ: CBLI) today announced the closing of a previously announced sale of an aggregate of $23.5 million of the Company's securities in a registered direct offering.

Michael Fonstein, Ph.D., President and Chief Executive Officer of Cleveland BioLabs, commented, "With the addition of these funds, we believe that we will be able to accelerate development of CBLB502, while continuing our pursuit of government agency funding. Our belief that CBLB502 is a strong candidate for ongoing support from our government partners is unchanged. Our top priority is to ensure the progression of CBLB502 towards potential licensure with the U.S. Food and Drug Administration (FDA) for reducing the risk of death following total body irradiation during or after a radiation disaster. The significantly increased financial flexibility gained in this transaction will enable us to advance CBLB502's development in both defense and medical indications, as well as move a few of our earlier stage programs closer to clinical studies."

The Company received net proceeds of approximately $22.0 million after deducting placement agent fees and other offering expenses. The Company sold an aggregate of approximately 5.873 million shares of its common stock and warrants exercisable for up to approximately 2.936 million additional shares of its common stock. The securities were sold in units at a price of $4.00 per unit, with each unit consisting of one share of common stock, a Series E Warrant to purchase 0.25 shares of common stock and a Series F Warrant to purchase 0.25 shares of common stock. The Series E Warrants are exercisable at a price of $4.50 per share beginning six months following the issuance date and will expire one year from the issuance date. The Series F Warrants are exercisable at a price of $5.00 per share beginning six months following the issuance date and will expire five years from the issuance date.

The Company intends to use the net proceeds from this offering for general corporate purposes, including, but not limited to, the funding of the continued development of the Company's existing drug portfolio and general working capital. Pending application of such proceeds, the Company expects to invest the proceeds in short-term, interest-bearing, investment-grade marketable securities or money market obligations.
