CELSION DEMANDS IMMEDIATE END TO UNAUTHORIZED TRADING ON BERLIN-BREMEN
STOCK EXCHANGE

COLUMBIA, MD - MAY 28, 2004: CELSION CORPORATION (AMEX: CLN) announced today
that it has learned that its common stock has been listed on the Berlin-Bremen
Stock Exchange without the Company's prior knowledge, consent or authorization.

The Company, through its counsel, has contacted the Berlin-Bremen Stock Exchange
and has demanded an immediate halt to trading in Celsion's stock, as well as an
immediate delisting of the stock.

Tony Deasey, Celsion's Executive Vice President and Chief Financial Officer,
said, "We did not apply for this listing. We were not consulted or contacted by
anyone at the Exchange, either before or after we were listed, and we certainly
did not request or consent to the listing. We have no interest in trading on the
Berlin-Bremen Exchange and are disturbed by media reports that brokers have been
using such listing as a mechanism for manipulating the price of U.S. stocks.
Therefore, our attorneys have demanded an immediate end to trading and immediate
delisting from the Exchange."

                 CELSION SUBMITS RESPONSE TO FDA WARNING LETTER

COLUMBIA, MD - JUNE 1, 2004: CELSION CORPORATION (AMEX: CLN) announced today
that its response to the warning letter issued to it by the Food and Drug
Administration (FDA) on May 7, 2004 was submitted to the FDA on Friday, May 28,
2004. As previously announced, the warning letter reflected certain matters that
arose in connection with the Phase I and Phase II clinical trials of Celsion's
Prolieve(TM) Thermodilatation system for the treatment of benign prostatic
hyperplasia. The FDA granted Premarketing Approval (PMA) to Celsion for the
Prolieve system earlier this year, and the system currently is being marketed
under a distribution agreement between Celsion and Boston Scientific
Corporation.

Tony Deasey, Celsion's Executive Vice President and Chief Operating Officer,
said, "We took, and continue to take, the FDA's letter extremely seriously and
have devoted significant attention and resources to our response. We believe
that we have responded to the FDA's immediate concerns and have initiated
actions necessary to address their longer-term comments on a schedule which,
based on discussions with the Agency, we believe will be acceptable. We are
putting processes in place to be fully compliant with FDA GCP regulations going
forward. Our actions in response to the FDA's findings should help us to meet
that goal and improve our clinical operations for the near and long term."

Carolyn Finkle, Celsion's Vice President, Regulatory Affairs, added, "We have
responded promptly to the findings raised by the FDA in its May 7, 2004 letter
and believe that we have addressed, or will address, all of the Agency's
concerns. So long as we do so and continue to work with the Agency, we do not
anticipate any further action by the FDA, including any actions that would
affect the Prolieve PMA." Ms. Finkle also indicated that the Company intends to
submit a redacted version of its response to the FDA shortly, with the request
that Celsion's response be posted for public review on the Agency's website at
www.fda.gov.
