                                (Title of Class)








Item 1.  Description of Registrant's Securities to be Registered.

         On August 6, 2002,  the Board of  Directors  (the  "Board")  of Celsion
Corporation  (the  "Corporation")   declared  a  dividend  distribution  of  one
preferred share purchase right (a "Right") for each outstanding  share of common
stock, par value $0.01 per share of the Corporation  (the "Common  Stock").  The
dividend is payable to the stockholders of record on August 6, 2002 (the "Record
Date"),  and with respect to shares of Common Stock issued  thereafter until the
Distribution Date (as defined below) and, in certain circumstances, with respect
to shares of Common Stock issued after the Distribution Date (as defined below).
Except as set forth below, when it becomes exercisable,  each Right entitles the
registered holder to purchase from the Corporation one ten-thousandth (1/10,000)
of a share of Series C Junior Participating Preferred Stock, par value $0.01 per
share of the Corporation  (the "Preferred  Stock"),  at a price of $4.46 per one
ten-thousandth  (1/10,000) of a share of Preferred Stock (the "Purchase Price"),
subject to adjustment.  The description and terms of the Rights are set forth in
a Rights Agreement (the "Agreement")  between the Corporation and American Stock
Transfer & Trust Company, as rights agent, dated as of August 15, 2002.

         Initially, the Rights will be attached to all certificates representing
shares of Common  Stock  outstanding  as of the  Record  Date,  and no  separate
certificates representing the Rights ("Right Certificates") will be distributed.
The Rights will  separate from the Common Stock upon the earlier to occur of (A)
a person or group of affiliated or associated persons having acquired Beneficial
Ownership (as defined in the Agreement) of fifteen  percent (15%) or more of the
outstanding  shares of Common  Stock or (B) ten (10) days (or such later date as
the Board  may  determine)  after the  commencement  of, or  announcement  of an
intention  to make,  a tender offer or exchange  offer the  completion  of which
would result in a person or group of affiliated or associated  persons  becoming
an  Acquiring  Person (as  defined  below) (in either  case,  the  "Distribution
Date").  A person or group whose  acquisition  of shares of Common Stock cause a
Distribution  Date pursuant to clause (A) above is an  "Acquiring  Person," with
certain  exceptions  set forth in the  Agreement.  The date on which a person or
group is first publicly announced to have become such by the Corporation or such
Acquiring  Person or an  earlier  date on which a majority  of the  then-sitting
members of the Board becomes aware of the existence of such Acquiring  Person is
referred to below and in the Agreement as the "Stock Acquisition Date".

         The Agreement  provides that, until the  Distribution  Date, the Rights
will be transferred only with the associated  shares of Common Stock.  Until the
Distribution  Date (or earlier  redemption  or  expiration  of the Rights),  new
Common  Stock  certificates  issued  after the Record Date upon  transfer or new
issuance of shares of Common  Stock will  contain a notation  incorporating  the
Agreement by reference;  however, the surrender for transfer of any certificates
for shares of Common Stock  outstanding as of the Record Date, even without such
notation  or a copy of the  Summary  of Rights (a copy of which is  attached  as
Exhibit C to the Agreement)  being attached  thereto,  will also  constitute the
transfer of the Rights associated with the shares of Common Stock represented by
such  certificate.  The  Rights  will  separate  from  the  Common  Stock on the
Distribution Date and, as soon as possible  thereafter,  Right Certificates will
be mailed to the holders of record of the shares of Common Stock as of the Close
of Business (as defined in the Agreement) on the Distribution  Date (and to each
initial  record  holder  of  certain  shares of Common  Stock  issued  after the
Distribution Date), and such separate Right Certificates alone will evidence the
Rights.

                                       2


         The Rights are not  exercisable  until the  Distribution  Date and will
expire at the Close of Business on August 15, 2012,  unless earlier  redeemed by
the Corporation as described below.

         If any person becomes an Acquiring Person,  each holder of a Right will
thereafter have the right (the "Flip-In Right") to receive,  upon exercise,  the
number  of  shares  of  Common   Stock  (or,  in  certain   circumstances,   one
ten-thousandth  (1/10,000) of a share of Preferred Stock) or other securities of
the Corporation having a value (immediately  before such triggering event) equal
to two (2) times the exercise price of the Right. Notwithstanding the foregoing,
after the Flip-In Right is triggered as described above, all Rights that are, or
(under  certain  circumstances  specified in the Agreement)  were,  Beneficially
Owned by any Acquiring Person or any affiliate or associate thereof will be null
and void.  The Board has the  option,  at any time after any  person  becomes an
Acquiring  Person but before an Acquiring Person becomes the Beneficial Owner of
fifty percent (50%) or more of the Common Stock,  to exchange all or part of the
then-exercisable  Rights (excluding those that have become void, as described in
the immediately  preceding sentence) for shares of Common Stock, at a one-to-one
exchange ratio.

         If, at any time after the Stock  Acquisition  Date, (A) the Corporation
consolidates or mergers with another Person (as defined in the  Agreement),  (B)
any Person merges with and into the Corporation,  with the Corporation being the
surviving  corporation  and, in connection with such merger,  all or part of the
Common Stock is changed into or exchanged  for stock or other  securities of any
other Person (or of the  Corporation) or cash or any other property,  or (C) the
Corporation sells or otherwise transfers, in one or more transactions, assets or
earning power aggregating fifty percent (50%) or more of its consolidated assets
or earning power to any other Person, then each holder of a Right (except Rights
which  previously have been voided as set forth above) shall thereafter have the
right (the "Flip-Over  Right") to receive,  upon exercise,  common shares of the
acquiring  company (or, in certain  circumstances,  its parent),  having a value
equal to two times the exercise  price of the Right.  The holder of a Right will
continue to have the  Flip-Over  Right  whether or not such holder  exercises or
surrenders the Flip-In Right.

         The Purchase  Price  payable,  the number of Rights,  and the number of
shares of  Preferred or Common Stock or other  securities  or property  issuable
upon  exercise  of the Rights are  subject  to  adjustment  from time to time in
connection  with the dilutive  issuances by the  Corporation as set forth in the
Agreement.  With certain exceptions, no adjustment in the Purchase Price will be
required  until  cumulative  adjustments  require an  adjustment of at least one
percent (1%) in such Purchase Price.

         The number of outstanding Rights and the number of one  ten-thousandths
(1/10,000s)  of a share of Preferred  Stock issuable upon exercise of each Right
are also subject to adjustment in the event of a stock split of the Common Stock
or a stock dividend on the Common Stock payable in Common Stock or subdivisions,
consolidations or combinations of the Common Stock occurring,  in any such case,
before the Distribution Date.

                                       3


         Preferred  Stock  purchasable  upon  exercise of the Rights will not be
redeemable.  Each share of  Preferred  Stock will be  entitled  to ten  thousand
(10,0000)  votes per share  (subject to customary  antidilution  provisions)  on
matters submitted to a vote of the  shareholders.  Each share of Preferred Stock
will be entitled to a minimum  preferential  quarterly  dividend payment of $100
per share but, if greater, will be entitled to a total dividend per share of ten
thousand  (10,000) times the dividend declared per share of Common Stock. In the
event of  liquidation,  the  holders  of shares of the  Preferred  Stock will be
entitled to a minimum  preferential  liquidation  payment per share in an amount
equal to the greater of $4.46 or ten  thousand  (10,000)  times the payment made
per share of Common Stock plus an amount  equal to accrued and unpaid  dividends
and distributions thereon, whether or not declared, to the date of such payment.
Finally, in the event of any merger, consolidation or other transaction in which
shares of Common  Stock are  exchanged,  each share of  Preferred  Stock will be
entitled to receive ten thousand (10,000) times the amount received per share of
Common Stock. These rights are protected by customary antidilution provisions.

         Because of the nature of the dividend,  liquidation  and voting rights,
the value of the one  ten-thousandth  (1/10,000)  of a share of Preferred  Stock
purchasable upon the exercise of a Right should approximate the value of one (1)
share of Common Stock.

         No  fractional  shares of  Preferred  Stock will be issued  (other than
fractions which are one  ten-thousandth  (1/10,000) or integral multiples of one
ten-thousandth  (1/10,000)  of a share of  Preferred  Stock,  which may,  at the
election of the  Corporation,  be evidenced by depositary  receipts) and in lieu
thereof,  an  adjustment  in cash will be made based on the market  price of the
Preferred Stock on the last trading day before the date of exercise.

         At any time  before the  earlier to occur of (A) a person  becoming  an
Acquiring  Person or (B) the  expiration of the Rights,  and under certain other
circumstances,  the Corporation may redeem the Rights in whole, but not in part,
at a price (payable in cash or, at the Corporation's  election, in Common Stock)
of $0.01 per Right (the "Redemption  Price").  Any redemption would be effective
upon the action of the Board.

         For so long as the Rights are then redeemable,  the Company may, except
with respect to the Redemption Price,  amend the Agreement in any manner.  After
the Rights are no longer redeemable, the Company may, except with respect to the
Redemption  Price,  amend the  Agreement  in any manner that does not  adversely
affect the interests of holders of the Rights.

         Until a Right is exercised,  the holder thereof,  as such, will have no
rights as a shareholder of the Corporation,  including,  without limitation, the
right to vote or to receive dividends. While the distribution of the Rights will
not be taxable to shareholders of the Corporation,  shareholders may,  depending
upon the  circumstances,  recognize  taxable  income  should the  Rights  become
exercisable or upon the occurrence of certain events thereafter.

         The  Rights  are   designed  to  protect  and  maximize  the  value  of
shareholders'  interests  in the  Corporation  in the  event  of an  unsolicited
takeover attempt in a manner or on terms not approved by the Board of Directors.
The Rights are not intended to prevent a takeover of the Corporation and are not
expected to do so. The Rights may be redeemed  by the  Company as  described  in
Section 23 of the Agreement,  and  accordingly,  the Rights should not interfere
with any merger or  business  combination  approved  by the Board of  Directors.
Issuance  of the Rights  should not weaken  the  Company or  interfere  with its
business plans.  The issuance of the Rights  themselves has no dilutive  effect,
will not  affect  reported  earnings  per  share,  should  not be taxable to the
Corporation  or to its  shareholders,  and will not  change the way in which the
Corporation's shares are presently traded. The Corporation's Board believes that
the Rights  represent a sound and  reasonable  means of  addressing  the complex
issues of corporate policy created by potential takeover attempts.  However, the
Rights  may have the effect of  rendering  more  difficult  or  discouraging  an
acquisition of the Corporation  deemed  undesirable by the Board. The Rights may
cause  substantial  dilution  to a person or group that  attempts to acquire the
Corporation  on terms or in a manner not  approved by the  Corporation's  Board,
except  pursuant  to  an  offer  conditioned  upon  the  negation,  purchase  or
redemption of the Rights.

                                       4


         As of August 6, 2002,  there  were  90,699,556  shares of Common  Stock
issued and outstanding.  As long as the Rights are attached to the Common Stock,
the Corporation  will issue one Right with each new share of Common Stock issued
so that all such shares will have Rights attached.

         The Agreement  (including,  attached as exhibits to the Agreement,  the
Form of Certificate of Designation for the Series C Junior Convertible Preferred
Stock,  the  Form  of  Right  Certificate,  and a  Summary  of  the  Rights)  is
incorporated  herein by reference as  indicated in Item 2 below.  The  foregoing
description  of the Rights is  qualified  in its  entirety by  reference to such
Agreement.
