        1.      Warrant to Purchase Common Stock.

                1.1     Warrant to Purchase Shares. This warrant (this
"Warrant") certifies that for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, Moors & Cabot, Inc. (the "Warrant
Holder") is entitled, effective as of January __, 2002, subject to the terms and
conditions of this Warrant, to purchase from Celsion Corporation, a Delaware
corporation (the "Company"), up to a total of ______________________________
(__________ ) units of the Company (the "Units") at a purchase price (the
"Exercise Price") of Sixty-Two and One Half Cents ($0.625) per Unit, at any time
prior to 5:00 p.m. prevailing Eastern time on January __, 2007 (the "Expiration
Date"). Each Unit will consist of one (1) share of the Company's common stock,
par value One Cent ($0.01) per share ("Share") and the right (the "Underlying
Warrant") to acquire one (1) Share ("Warrant Share") at a price of Sixty Cents
($0.60) per share (the "Underlying Warrant Exercise Price") prior to the
Expiration Date. . The Underlying Warrant must also be exercised, in whole or in
part, any time on or before the Expiration Date, subject to earlier call by the
Company as provided herein. Unless the context otherwise requires, the term
"Shares" shall mean and include the Common Stock of the Company and other
securities and property at any time receivable or issuable upon exercise of this
Warrant. The term "Warrant" as used herein, shall include this Warrant and any
warrants delivered in substitution or exchange therefor as provided herein.

                1.2     Adjustment of Exercise Price and Number of Shares. The
number and character of Units issuable upon exercise of this Warrant and the
Underlying Warrant (or any shares of stock or other securities or property at
the time receivable or issuable upon exercise of this Warrant and the Underlying
Warrant) and the Exercise Price therefor, are subject to adjustment upon
occurrence of the following events:



                        (a)     Adjustment for Stock Splits, Stock Dividends,
Recapitalizations, etc. The Exercise Price of this Warrant and the number of
Units issuable upon exercise of this Warrant, as well as the Underlying Warrant
Exercise Price and the number of Shares issuable upon exercise of the Underlying
Warrant shall each be proportionally adjusted to reflect any stock dividend,
stock split, reverse stock split, combination of shares, reclassification,
recapitalization or other similar event altering the number of outstanding
shares of the Company's Common Stock.



                        (b)     Adjustment for Capital Reorganization,
Consolidation, Merger. If any capital reorganization of the capital stock of the
Company, or any consolidation or merger of the Company with or into another
corporation, or the sale of all or substantially all of the Company's assets to
another corporation shall be effected in such a way that holders of the
Company's Common Stock will be entitled to receive stock, securities or assets
with respect to or in exchange for the Company's Common Stock, then in each such
case the Warrant Holder, upon the exercise of this Warrant and the Underlying
Warrant at any time after the consummation of such capital reorganization,
consolidation, merger, or sale, shall be entitled to receive, in lieu of the
stock or other securities and property receivable upon the exercise of this
Warrant and the Underlying Warrant prior to such consummation, the stock or
other securities or property to which such Warrant Holder would have been
entitled upon such consummation if such Warrant Holder had exercised this
Warrant and the Underlying Warrant immediately prior to the consummation of such
capital reorganization, consolidation, merger, or sale, all subject to further
adjustment as provided in this Section 1.2; and in each such case, the terms of
this Warrant and the Underlying Warrant shall be applicable to the shares of
stock or other securities or property receivable upon the exercise of this
Warrant after such consummation.

        2.      Manner of Exercise.

                2.1     Warrant Exercise Agreement. This Warrant may be
exercised, in whole or in part, on any business day on or prior to the
Expiration Date, subject to earlier call by the Company as provided herein. To
exercise this Warrant, the Warrant Holder must surrender to the Company this
Warrant and deliver to the Company: (a) a duly executed exercise agreement in
the form attached hereto as Exhibit A, or in such other form as may be approved
by the Company from time to time (the "Warrant Exercise Agreement"); and (b)
payment in full of the Exercise Price for the number of Units to be purchased
upon exercise hereof. If someone other than the Warrant Holder exercises this
Warrant, then such person must submit to the Company each of the items set forth
in clauses (a) and (b) of the foregoing sentence and, in addition, must submit
(c) documentation acceptable to the Company that such person has the right to
exercise this Warrant and (d) if applicable, a spousal consent in the form
attached hereto as Exhibit B. Upon a partial exercise, this Warrant shall be
surrendered, and a new warrant of the same tenor for purchase of the number of
remaining Units not previously purchased shall be issued by the Company to the
Warrant Holder. This Warrant shall be deemed to have been exercised immediately
prior to the close of business on the date of its surrender of, if such date is
not a business day, then as of the close of business on the next succeeding
business day, for exercise as provided above, and the person entitled to receive
the Shares issuable upon such exercise shall be treated for all purposes as the

exercise date.

exercise of this Warrant, the Warrant Holder must pay or provide for any
applicable federal or state withholding obligations of the Company.

provided, however, that any such redemptions and cancellations may be made by
the Company only upon thirty (30) calendar days' prior written notice (the
"Redemption Date" being the close of business on the thirtieth (30th) day

Warrant subject to such redemption and cancellation may exercise such Warrant at
any time prior to the expiration of the thirty (30)-day notice period; and
provided further that the Company's right to redeem and cancel the Warrant shall
be suspended in the event the shelf registration statement required under
Section 4 of the Subscription Agreement is subject to a stop order or is
otherwise not in effect or if the Warrant Holder is advised under Section 4(c)

permitted partial transfer, the Company will issue and deliver to the Warrant

portion hereof, by taking or holding the same, consents and agrees to be bound
by the terms, conditions, representations and warranties hereof, including the
registration provisions contained in Section 4 of the Subscription Agreement,
(and as a condition to any transfer of this Warrant the transferee shall execute
an agreement confirming the same), and, when this Warrant shall have been so
endorsed, the person in possession of this Warrant may be treated by the
Company, and all other persons dealing with this Warrant, as the absolute owner
hereof for any purpose and as the person entitled to exercise the rights
represented hereby, any notice to the contrary notwithstanding; provided,
however that until a transfer of this Warrant is duly registered on the books of
the Company or its agent, the Company may treat the Warrant Holder hereof as the
owner of this Warrant for all purposes.

        7.      Privileges of Stock Ownership. The Warrant Holder shall not have
any of the rights of a shareholder with respect to any Shares or Warrant Shares

Exercise Price in accordance with the terms hereof or of the Underlying Warrant,
as the case may be.

        8.      Entire Agreement. The Warrant Exercise Agreement is incorporated
herein by reference. This Warrant, the Warrant Exercise Agreement, and the
Subscription Agreement for the purposes and to the extent set forth herein,
constitute the entire agreement of the parties and supersede all prior
