         This prospectus supplement will be used by the holders of common stock,
par value $.01 per share (the "Common Stock"), of Celsion Corporation, a

(including accrued dividends), and up to 3,600,000 Shares issuable upon the
exercise of the Warrants.

         The table below supplements the information set forth under the caption
"Resales by Selling Stockholders" in the Prospectus and, to the extent

         The Selling Stockholders named in the table below acquired, in the
aggregate, Warrants to purchase 600,000 Shares through transfers of Warrants to
purchase 600,000 Shares from certain Selling Stockholders named in the

Selling Stockholder named herein as of August 5, 2003: (i) the name of the

beneficially owned before this offering; (iii) the number of Shares the Selling
Stockholder is offering hereby; (iv) the total number of outstanding shares of
Common Stock that the Selling Stockholder will beneficially own, assuming that
the Selling Stockholder sells all of the Shares held thereby subject to this
offering; and (v) that number of shares as a percentage of the total number of
shares of Common Stock outstanding. Except as set forth in the table below, none
of the Selling Stockholders named herein has had a material relationship with us

----------
(1)      We have computed "beneficial ownership" in accordance with Rule
         13d-3(d) promulgated by the SEC under the Securities Exchange Act of
         1934 for purposes of this table. Therefore, the table reflects a person
         as having "beneficial ownership" of shares of Common Stock if such
         person has the right to acquire such shares within 60 days of August 5,
         2003. For purposes of computing the percentage of outstanding shares of
         Common Stock held by each person or group of persons named above, we
         have assumed to be outstanding any security which such person or
         persons has or have the right to acquire within that 60-day period. All
         of the Warrants are currently exercisable and, therefore, the Selling
         Stockholders may be deemed to be the beneficial owner of the Shares of
         Common Stock underlying such Warrants pursuant to Rule 13d-3(d).
         However, securities that may be acquired within that 60-day period are
         not deemed to be outstanding for purposes of computing the percentage
         ownership of any other person. Notwithstanding the foregoing, for
         purposes of this table, we have not included the Shares underlying
         Warrants and registered hereby under the column "Securities
         Beneficially Owned Prior to Offering--Common Stock." Instead, such
         Shares are reflected under the column "Securities Offered Hereby."
         Except as indicated in the footnotes to this table and pursuant to
         applicable community property laws, the Company believes, based on
         information supplied by such persons, that the persons named in this
         table have sole voting and investment power with respect to all shares
         of Common Stock which they beneficially own.

(2)      Represents the maximum number of Shares issuable to each Selling
         Stockholder upon exercise in full of Warrants issued or issuable
         thereto.

(3)      Assumes the eventual sale of all Shares by each Selling Stockholder.
         There can be no assurance that any Selling Stockholder will sell any or
         all of such Shares owned thereby or issuable thereto.

(4)      Warrants to purchase 600,000 Shares were acquired pursuant to a
         transfer from Kim R. Baker, who no longer holds Shares or Shares
         subject to Warrants subject to resale pursuant to the Prospectus.
