         RE:   CELSION CORPORATION--INTRODUCTION OF
               STRATEGIC CANADIAN AND HONG KONG INVESTORS

Dear Sir:

We refer to the various discussions with you recently and propose to act as an
advisor to Celsion Corporation (the "COMPANY") in respect of the introduction of
strategic investors in Canada and Hong Kong (the "ENGAGEMENT") on the terms and
conditions set forth in this letter agreement (this "AGREEMENT").

1. BACKGROUND INFORMATION

        Based on our various discussions, we understand the following:

           (A)    The Company is a research and development company dedicated to
                  commercializing medical treatment systems, for cancer and
                  other diseases using focused heat technology delivered by
                  patented microwave technology,

           (B)    The Company currently is seeking US$6-US$9 million through one
                  or more private placements either within the United States or
                  abroad to fund its further development and the
                  commercialization of certain of its products (collectively,
                  the "FINANCING").

           (C)    The Company has retained Sterling Financial Investment Group,
                  Inc. ("STERLING") to serve as placement agent with respect to
                  effecting the Financing with investors within the United
                  States and, in consultation with STERLING, has developed a
                  package of information to be utilized in connection with the
                  Financing (the "PRIVATE PLACEMENT PACKAGE").

2. SCOPE OF SERVICES

        Goldpac Investment Partners Ltd., a British Virgin Islands corporation
("GOLDPAC") shall act as an advisor to the Company with respect to potential
participation in the Financing by one or more investors in Canada and/or Hong
Kong. In its role as advisor, Goldpac will, at the request and subject to the
control of the Company, identify, on a "best efforts" basis, investors who are
residents of Canada and/or Hong Kong (or otherwise are non-resident aliens in
the United States) willing to make an aggregate investment of up to US$3.0
million pursuant to the Financing and facilitate meetings between such potential
investors and Company representatives. In addition, to the extent that the
Company deems necessary and appropriate and so directs Goldpac, Goldpac will
arrange road shows in Hong Kong and/or Canada for such potential investors. All
activities of Goldpac will be conducted outside of the United States and all
investors





identified or contacted by Goldpac will be either individuals who are neither
U.S. citizens, nor resident aliens of the U.S. or who are foreign (non-U.S.)
corporations or other entities not engaged in any U.S. trade or business
("PERMITTED INVESTORS"). Anything to the contrary contained herein
notwithstanding, Celsion shall have the right, in its sole and absolute
discretion, to reject any proposed investment from any Permitted Investor for
any reason or for no reason.

3.      FEE STRUCTURE

        As compensation for its services hereunder, Celsion shall compensate
Goldpac as follows:

           (A) The Company shall pay to Goldpac a Success Fee, in U.S.
               dollars, in an amount equal to seven and one half percent (7.5%)
               of the purchase price of any securities of Celsion purchased by
               Permitted Investors introduced to the Company by Goldpac.

           (B) The Company will grant to Goldpac common stock purchase
               warrants ("WARRANTS"), exercisable for a period of five (5) years
               from the date of the final closing of the Financing, at an
               exercise price equal to the price per common share paid by the
               Permitted Investors. Goldpac shall be entitled to receive
               Warrants to purchase nine (9) shares of the Company's Common
               Stock, par value $0.01 per share, for each 100 shares acquired in
               the Financing by each Permitted Investor introduced to the
               Company by Goldpac pursuant hereto. Additionally, Goldpac shall
               be entitled to receive Warrants to purchase nine (9) shares of
               the Company's Common Stock, par value $0.01 per share, for each
               warrant to purchase100 shares acquired by each Permitted Investor

               Agreement and will be subject to extension or renewal upon mutual
               agreement by the parties.

           (B) The Engagement may be terminated by the Company or by Goldpac
               at any time, for any reason, upon written notice to that effect
               to Goldpac or the Company, as the case may be; provided, however,
               that Sections 3(A), 3(B), 7, 8 and 9 under this Agreement shall
               survive any such termination and shall remain in full force and
               effect.

6.         REPRESENTATIONS AND WARRANTIES

           (A) The Company hereby represents and warrants to Goldpac that, as of

                           existing and in good standing under the laws of the
                           State of Delaware. The Company has all necessary
                           corporate power and authority to own its assets and

                           presently proposed to be conducted. The Company is
                           duly qualified to do business as a foreign
                           corporation and is in good standing in each
                           jurisdiction in which its ownership or leasing of
                           assets, or the conduct of its business, makes such
                           qualification necessary, except where the failure to
                           be so qualified or in good standing would not have a
                           material adverse effect on the Company.

                  (2)      The Company has all necessary corporate power and
                           authority to execute, deliver and carry out the terms

                           of the Company required for the lawful execution and
                           delivery of this Agreement has been taken. Upon
                           execution and delivery, this Agreement constitutes a
                           valid and binding obligation of the Company,
                           enforceable in accordance with its terms, except as
                           enforcement may be limited by insolvency and similar
                           laws affecting the enforcement of creditors' rights
                           generally and equitable; remedies, and except as the
                           indemnity Provisions or Section 7 this Agreement may
                           be limited by law.





                  (3)      Neither the execution and delivery of, nor the
                           consummation by the Company of any transaction or
                           execution of any instrument contemplated by, this
                           Agreement has constituted or resulted in, or will
                           constitute or result in, a material default under or
                           breach or violation of any term or provision of the
                           Company's Bylaws, Certificate of Incorporation or of
                           any material contracts with third parties.

                           corporate power and authority to own its assets and
                           to carry on its business as now being conducted and
                           presently proposed to be conducted. Goldpac is duly
                           qualified to do business as a foreign corporation and
                           is in good standing in each jurisdiction in which its
                           ownership or leasing of assets, or the conduct of its
                           business, makes such qualification necessary, except
                           where the failure to be so qualified or in good
                           standing would not have a material adverse effect on
                           Goldpac.

                  (2)      Goldpac has all necessary corporate power and
                           authority to execute, deliver and carry out the terms

                           delivery of this Agreement has been taken. Upon
                           execution and delivery, this Agreement constitutes a
                           valid and binding obligation of Goldpac, enforceable
                           in accordance with its terms, except as enforcement
                           may be limited by insolvency and similar laws
                           affecting the enforcement of creditors' rights
                           generally and equitable remedies, and except as the
                           indemnity provisions of Section 7 of this Agreement
                           may be limited by law.





                  (3)      Neither the execution and delivery of, nor the
                           consummation by Goldpac of any transaction or
                           execution of any instrument contemplated by, this
                           Agreement, has constituted or resulted in, or will
                           constitute or result in, a material default under or
                           breach or violation of any term or provision of
                           Goldpac's Bylaws, Certificate of Incorporation, other
                           constitutive documents, or material contracts with
                           third parties, or of the laws of the United States or
                           any jurisdiction thereof or of any non-U.S.,
                           jurisdiction or any rules or regulations thereunder.
                           Without limiting the generality of the foregoing,
                           Goldpac acknowledges and agrees that it is

                    provided in Section 7(B) below and to the extent that any
                    claims, damages, liability or expenses are found in a final
                    judgment by a court of competent jurisdiction to have
                    resulted from Goldpac's misconduct or negligence in
                    performing the services described above. The indemnity
                    provisions contained in this Section 7(A) will remain in

                    including, without limitation, (i) any untrue statement or
                    alleged untrue statement of a material fact, made either
                    orally or in writing or any omission or alleged omission to
                    state a material fact by Goldpac or any Goldpac
                    Representative in connection with this Agreement or the
                    Engagement, (ii) the failure of Goldpac to comply with any
                    laws of any jurisdiction applicable to it by virtue of its
                    activities pursuant this Agreement or the Engagement or
                    otherwise as contemplated by Section 6(B)(3) hereof, or
                    (iii) any violation of any securities laws, rules and
                    regulations applicable to Goldpac, to the Company or to the

                    Agreement or the Engagement.

                (C) If for any reason the foregoing indemnity is unavailable
                    to Goldpac and the Goldpac Representatives on the one hand,
                    or to the Company and the Company Representatives on the
                    other (each, an "Indemnified Person") or is insufficient to
                    hold the Indemnified Person harmless, then the party
                    required to provide indemnification hereunder (the

                    claims, liability, loss or damage in such proportion as is
                    appropriate to reflect not only the relative benefits
                    received by the Indemnifying Person on the




                    one hand and the Indemnified Person on the other, but also

                    hand, and Indemnified Person on the other, that result in

                    relevant suitable considerations. The contribution
                    provisions contained in this Section shall remain in full
                    force and effect regardless of the termination of this
                    Agreement or the Engagement.

Goldpac Representatives or are required to be disclosed by applicable law. With
respect to disclosures required by law, prior to making any such disclosure
Goldpac will provide the Company with a written opinion of Goldpac's counsel to

               law.

            B) This Agreement shall be assignable by either party only upon
               the prior written consent of the other party. Subject to the
               foregoing, this Agreement shall be binding upon, and shall inure
               to the benefit of, the parties hereto and their respective

           (C) In the event that any one or more of the provisions contained
               in this Agreement, or the application thereof to any person(s) or
               under any circumstance(s), shall, for any reason, be found by a
               regulatory body or court of competent jurisdiction to be invalid,
               illegal or unenforceable, such regulatory body or court shall
               have the power, and hereby is directed, to substitute for or
               limit such provision(s) in order as closely as possible to
               effectuate the original intent of the parties with respect to
