Celsion Announces Boston Scientific Exercises Its Option to Purchase Prolieve(R) Assets

Celsion's Board of Directors Recommends that Its Stockholders Approve the Purchase of Prolieve Assets by Boston Scientific

COLUMBIA, Md.--(HSMN NewsFeed)--Celsion CorpORATION (AMEX:CLN ) today announced that it has entered into an Asset Purchase Agreement under which Boston Scientific Corporation (NYSE:BSX ) will purchase the Company's Prolieve assets for $60 million, subject to reduction under certain circumstances. The Asset Purchase Agreement contains customary terms and conditions, including approval by Celsion's stockholders.

The Asset Purchase Agreement is different in certain key aspects from the Transaction Agreement entered into between Celsion and Boston Scientific on January 20, 2003, as amended on August 7, 2005. In particular, instead of paying $60 million for the Prolieve assets on the date of closing, Boston Scientific will pay $30 million at closing, $15 million on the first anniversary of the closing and up to $15 million on the second anniversary of the closing. The $30 million payable at closing will be reduced by approximately $17 million, representing the principal and accrued interest due on three promissory notes previously issued by Celsion to Boston Scientific. The Asset Purchase Agreement also contains customary indemnification provisions, including for breaches of representations, warranties and covenants contained in the Asset Purchase Agreement.

Stockholders will be asked to approve the transaction at the Company's annual meeting of stockholders currently scheduled for June 13, 2007.

"We are pleased that Boston Scientific has decided to exercise its option to purchase our Prolieve assets earlier than required, well in advance of the expiration of the option, under its original agreement with Celsion," said Michael H. Tardugno, Celsion's President and Chief Executive Officer. "The sale of the Prolieve assets will complete Celsion's transition to an oncology focused drug company, enabling us to fully focus our resources on the development of our lead drug ThermoDox(TM). The installment based payout will provide immediate non-dilutive funding sufficient for us to initiate and make substantial progress with our lead Phase III and II clinical trials for primary liver and recurrent chest wall breast cancers, respectively."

Mr. Tardugno went on to say, "We believe the Company's heat activated liposome technology platform holds great promise of future value creation for our stockholders. The gain generated by the asset sale will result in a significant increase in stockholder equity and put us on schedule to fully comply with the AMEX listing criteria within the time frame agreed upon with the exchange."
