4.)     Celsion agrees to reimburse EC for direct costs incurred by it on
Celsion's behalf for long distance telephone charges, photocopying, fax
transmissions, postage, messenger and courier service, express delivery

to Celsion and will not exceed $750 per month in the aggregate without the
express approval of a Celsion officer.

        (4a.)  The following items, which would require EC to utilize outside
        vendors and/or supervise the work of others (which Celsion does not at
        the present time expect to need) would, if required, be rebilled to
        the Company only as authorized, and include a standard service fee of
        17.64%: printing, production, package distribution, mailing list
        development and maintenance, art work, consultants, photography, and

5.)     The cost of travel, at coach-class rates, will be reimbursed by
Celsion, and all travel commitments involving costs to be so reimbursed will
be approved by Celsion in advance. Where possible, transportation arrangements
involving service for Celsion will be made by a travel agent designated by the
Company, and such transportation will be billed directly to Celsion by the
agent. In the event Mr. Weingarten or Mr. Chizzik must fly cross-country
utilizing red-eye service, they shall be entitled to fly business class, or
first class if business class is not available using the least possible
airfare, such as frequent flyer upgrades, etc.

review and approval; responding to shareholder inquiries; editorial assistance
in the development of discussion materials, business plans and shareholder
letters as may be appropriate; and assistance as may be needed in helping
Celsion to clarify and implement its long term financial objectives.

Cooperation by both parties to insure uninterrupted communications is
presumed. Celsion agrees to keep EC continuously informed of its progress; to
supply information necessary to produce releases, letters and reports in a
timely manner, and to review such documents for accuracy and completeness
before their dissemination to the public.
