                                  COMMON STOCK

         This Prospectus of Celsion Corporation, or the Company, a Delaware
corporation, relates to the offer and sale from time to time by certain selling
stockholders (the "Selling Stockholders") of up to 8,652,441 shares of the
Company's common stock, par value $0.01 per share (the "Common Stock") that are
presently outstanding, and up 4,723,698 shares of Common Stock issuable upon the
exercise of certain Common Stock purchase warrants (the "Warrants"). The shares
of Common Stock offered hereby are referred to collectively as the "Shares." See
"Selling Stockholders" and "Plan of Distribution."

         The Company will not receive any proceeds from sales of Shares by the
Selling Stockholders. However, the Company will receive proceeds upon exercise
of the Warrants, up to a maximum of $4,604,032, if all of the Warrants are
exercised for cash.

         The Selling Stockholders or pledgees, donees, transferees or other
successors in interest that receive Shares by way of gift, partnership
distribution or other non-sale transfer, may offer and sell some, all or none of
the Shares under this Prospectus. The Selling Stockholders or their successors
may determine the prices at which they will sell their Shares, which may be the
then-prevailing market price or some other price. In connection with such sales,
the Selling Stockholders or their successors may use brokers or dealers, who may
receive compensation or commissions for such sales. The Company has agreed to
bear all expenses in connection with the registration of the Shares. However,
the Selling Stockholders will pay any brokerage commissions, discounts and fees
in connection with the sale of their Shares. A Selling Stockholder's net
proceeds from the sale of Shares will be the sales price of the Shares sold for
the account of such Selling Stockholder, less applicable commissions, discounts
and fees.


         The Common Stock is traded on The American Stock Exchange under the
symbol "CLN." On June 9, the closing price of the Common Stock on The American
Stock Exchange was $0.67.

GENERAL

         Celsion Corporation, based in Columbia, Maryland, is a biotechnology
company dedicated to the development and commercialization of treatment systems
for cancer and other diseases using focused heat energy, either administered
alone or in combination with other therapeutic devices, heat-activated genes and
heat-activated drugs. In February 2004 we received premarketing approval (PMA)
from the Food and Drug Administration, or FDA for our Prolieve(TM)
Thermodilatation system for the treatment of Benign Prostatic Hyperplasia, or
BPH, a chronic condition of enlargement of the prostate common in older men, and
have begun to market. We also are currently in active clinical development and
testing of (i) systems using our Adaptive Phased Array (APA) focused microwave
technology, licensed from the Massachusetts Institute of Technology (MIT), to
treat both early stage cancer and locally advanced breast cancer, and (ii)
heat-activated liposome technology, licensed from Duke University, to deliver
chemotherapeutic drugs for the treatment of prostate and liver cancer. In
addition, our gene-based Cancer Repair Inhibitor (CRI), licensed from Memorial
Sloan-Kettering Cancer Center (Sloan-Kettering), is in late-stage animal testing

BPH TREATMENT SYSTEM

         BENIGN PROSTATIC HYPERPLASIA

         Millions of aging men experience symptoms resulting from BPH, a
non-cancerous urological disease in which the prostate enlarges and constricts
the urethra. The prostate is a walnut-sized gland surrounding the male urethra
that produces seminal fluid and plays a key role in sperm preservation and
transportation. The prostate frequently enlarges with age. As the prostate
expands, it compresses or constricts the urethra, thereby restricting the normal
passage of urine. This restriction of the urethra may require a patient to exert
excessive bladder pressure to urinate. Because the urination process is one of
the body's primary means of cleansing impurities, the inability to urinate
adequately increases the possibility of infection and bladder and kidney damage.

         PREVALENCE OF BPH

         As BPH is an age-related disorder, its incidence increases with
maturation of the population. Industry estimates suggest that 9 million men in
the United States experience BPH symptoms and that more than 26 million men are
affected by BPH worldwide. As the United States population continues to age, the
prevalence of BPH can be expected to continue to increase. It is generally
estimated that approximately 50% of all men over the age of 55 and 90% of all
men over 75 will have BPH symptoms at various times. Industry studies estimate
the overall costs of BPH therapy for those patients currently seeking treatment
to be approximately $2.5 to $3.0 billion annually in the United States and $8.0
to $10.0 billion worldwide.

         CURRENT TREATMENT ALTERNATIVES FOR BPH

         Like cancerous tumors, BPH historically has been treated by surgical
intervention or by drug therapy. The primary treatment for BPH currently is
transurethral resection of the prostate, or TURP, a surgical procedure in which
the prostatic urethra and surrounding diseased tissue in the prostate are
trimmed with a telescopic knife, thereby widening the urethral channel for urine
flow. While the TURP procedure typically has been considered the most effective
treatment available for the relief of BPH symptoms, the procedure has
shortcomings. In the first instance, TURP generally requires from one to three
days of post-operative hospitalization. In addition, a significant percentage of
patients who undergo TURP encounter significant complications, which can include
painful urination, infection, retrograde ejaculation, impotence, incontinence
and excessive bleeding. Furthermore, the cost of the TURP procedure and the
related hospitalization is high, ranging from $8,000 to $12,000. This cost does
not take into account the costs of lost work time, which could amount to several
weeks, or the costs related to adverse effects on patients' quality of life.

         Other, less radical, surgical procedures, generally categorized as
"minimally invasive" (MI) therapies, are available as alternatives to the TURP
procedure. The primary MI treatments use microwave heating (TUMT) to treat BPH
by incinerating the obstructing portion of the prostate. TUMT involves sedation,
catheterization and high levels of heat to incinerate a portion of the prostate.
Two other MI therapies-- interstitial RF therapy and laser therapy - employ,
respectively, concentrated radio frequency (RF)


                                       3



waves or laser radiation to reduce prostate swelling by cauterizing tissue
instead of removing it with a surgical knife. However, these procedures require
puncture incisions in order to insert cauterizing RF or laser probes into the
affected tissue and, therefore, also involve the use of a full operating
facility and anesthesia, as well as the burning of prostate tissue by the
probes. Although these procedures result in less internal bleeding and damage to
the urethra than the TURP procedure and may decrease the adverse effects and
costs associated with surgery, anesthesia and post-operative tissue recovery,
they do not entirely eliminate these adverse consequences.

         Finally, drug therapy has emerged as an alternative to surgery in the
last several years. There are several drugs available for BPH treatment, the two
most widely prescribed being Hytrin and Proscar. Hytrin works by relaxing
certain involuntary muscles surrounding the urethra, thereby easing urinary
flow, and Proscar is intended actually to shrink the enlarged gland. However,
industry studies have asserted that drug therapy costs $500 to $800 per year or
more, must be maintained for life and does not offer consistent relief to a
large number of BPH patients. In fact, studies have shown that 45% of patients
who begin drug therapy for BPH drop out within the first year, primarily due to
the ineffectiveness of currently available drug therapies. Also, all of the
currently available BPH drugs have appreciable side effects.

         Accordingly, neither the medicinal treatments nor the surgical
alternatives available for BPH appear to provide fully satisfactory,
cost-effective treatment solutions for BPH sufferers.

         CELSION BPH TREATMENT SYSTEM

         We have developed our Prolieve Thermodilatation system, a BPH treatment
system that combines our microwave thermotherapy capability with a proprietary
balloon compression technology licensed from MMTC, Inc. The system consists of a
microwave generator and conductors and a computer and computer software programs
that control the focusing and application of heat, plus a specially designed
balloon catheter and consists of two fundamental elements:

         o   Celsion's proprietary catheter, incorporating a balloon enlargement
             device, delivers computer-controlled transurethral microwave
             heating directly to the prostate at temperatures greater than
             44(degree) C (111(degree) F).

         o   Simultaneously, the balloon inflates the device and expands to
             press the walls of the urethra from the inside outward as the
             surrounding prostate tissue is heated.

The combined effect of this "heat plus compression" therapy is twofold: first,
the heat denatures the proteins in the wall of the urethra, causing a stiffening
of the opening created by the inflated balloon. Second, the heat serves
effectively to kill off prostate cells outside the wall of the urethra, thereby
creating sufficient space for the enlarged natural opening.

         Pre-clinical animal studies have demonstrated that a natural "stent,"
or reinforced opening, in the urethra forms after the combined heat plus
compression treatment. Also, the Prolieve system's relatively low temperature
(43(degree) C to 45(degree) C) appears to be sufficient to kill prostatic cells
surrounding the urethra wall, thereby creating space for the enlargement of the
urethra opening. However, the temperature is not high enough to cause swelling
in the urethra.

         Celsion's Prolieve Thermodilatation system treatment system is designed
to overcome the limitations of all three of the current treatment systems. It is
designed to be a relatively painless, rapid procedure that delivers the efficacy
of surgical treatments without significant risks and the potential for
life-altering side effects. The potential benefits of the Prolieve system
include walk-in, outpatient treatment that can be completed in less than an
hour; no required sedation; generally no post-operative catheterization; and
rapid symptomatic relief from BPH.

         We recently completed the FDA approval process and received a PMA,
which permitted us to begin to market the Prolieve system, on February 19, 2004.
Since that time we have begun to market the Prolieve system through Boston
Scientific Corporation, with which we entered into a strategic relationship in
January 2003.

         We have received a warning letter from the FDA regarding the Phase I
and Phase II clinical trials of the Prolieve system. The warning letter reflects
matters that arose during the course of an inspection conducted by the FDA's
Baltimore regional office from December 9 through December 18, 2003 under a
program designed to ensure that data and information contained in certain
submissions to the FDA, including PMA applications, are scientifically valid and
accurate and to ensure that human subjects are protected from undue hazard or
risk during scientific investigations.

         The warning letter addressed four general areas--monitoring,
investigational agreements, provision of information to certain investigators,
and FDA reporting--in connection with the Prolieve studies, both of which were
completed by January 2002. Subsequent to the inspection, we took certain actions
to address the observations of the FDA inspector and on December 23, 2003, made
a written submission to the agency regarding those corrective and compliance
actions. In addition, since receipt of the warning letter, the Company has
spoken with representatives of the FDA regarding compliance matters and has
initiated short- and long-term corrective and compliance measures to address
fully the issues raised by the FDA.

         PREVALENCE OF BREAST CANCER

         Breast cancer is one of the leading causes of death among women in the
United States. According to statistics published in the American Cancer
Society's A Cancer Journal for Clinicians, there were an average of 183,000
newly diagnosed breast cancer cases in the United States in each of the years
from 1995 through 1999.

         CURRENT TREATMENT FOR BREAST CANCER

         Breast cancer is presently treated by mastectomy, the surgical removal
of the entire breast, or by lumpectomy, the surgical removal of the tumor and
surrounding tissue. Both procedures are often followed by radiation therapy or
chemotherapy. The more severe forms of surgical intervention can result in
disfigurement and a need for extended prosthetic and rehabilitation therapy.

         In addition, heat therapy (also known as hyperthermia or thermotherapy)
is a historically recognized method of treatment of various medical conditions,
and heat therapy has been used in the past to treat malignant tumors in
conjunction with radiation and chemotherapy. As summarized in the Fourth Edition
of Radiobiology for the Radiologist, published in 1994 by J.B. Lippincott
Company, in 24 independent studies on an aggregate of 2,234 tumors, treatment
consisting of heat plus radiation resulted in an average doubling of the
complete response rate of tumors, compared to the use of radiation alone. The
complete response rate for this purpose means the total absence of a treated
tumor for a minimum of two years. Comparable increases in the complete response
rate were reported with the use of heat combined with chemotherapy. In addition,
it has been demonstrated on numerous occasions that properly applied heat, alone
and without the concurrent use of radiation, can also kill cancer cells.

         HEAT THERAPY IN CONJUNCTION WITH RADIATION; FIRST GENERATION CELSION
         EQUIPMENT

         In 1989, we obtained FDA premarketing approval for our microwave-based
Microfocus 1000 heat therapy equipment for use on surface and subsurface tumors
in conjunction with radiation therapy. Until 1995, we marketed our Microfocus
equipment for this use in 23 countries, but microwave heat therapy was not
widely accepted in the United States medical community as an effective cancer
treatment. Moreover, due to the limitations of microwave technology available at
that time, it was difficult to deliver a controlled amount of heat to subsurface
tumors without overheating surrounding healthy tissue.

         NEW MICROWAVE TECHNOLOGY FROM MIT

         In 1993, we began working with researchers at the Massachusetts
Institute of Technology who had developed, originally for the United States
Defense Department, the microwave control technology known as "Adaptive Phased
Array" (APA). This technology permits properly designed microwave equipment to
focus and concentrate energy targeted at diseased tissue areas deep within the
body and to heat them selectively, without adverse impact on surrounding healthy
tissue. In 1996, MIT granted us an exclusive worldwide license to use this
technology for medical applications and since that time we have concentrated on
developing a second generation of equipment capable of focusing microwave energy
on specific tissue areas. We have incorporated the APA technology in our
second-generation microwave therapy equipment.

         SECOND GENERATION CELSION BREAST CANCER TREATMENT SYSTEM

         Using the APA technology, we have developed a prototype breast cancer
treatment system intended to destroy localized breast tumors through the
application of heat alone. The system consists of a microwave generator and
conductors, a computer and computer software programs that control the focusing,
application and duration of the thermotherapy, and a specially designed patient
treatment table.

         In 1998, we completed pre-clinical animal testing of our prototype
system at the Massachusetts General Hospital, a teaching hospital for Harvard
Medical School in Boston, Massachusetts. Using breast tissue-equivalent phantoms
and tumors in live animals, these studies demonstrated that our system is
capable of selectively heating tumors at temperatures up to 46(degree) C
(115(degree) F) without damage to surrounding healthy tissues. High temperatures
maintained for eight to ten minutes can cause complete tumor necrosis (death),
leading to the death of viable cancer cells within the tumor and in its
immediate vicinity. A second prototype clinical breast cancer treatment system
at Oxford University in England was used to demonstrate successfully the ability
of our equipment to focus heat deep into animal tissue at precise locations and
in small target areas. In our view, these animal tests demonstrate that it is
possible to eliminate tumors by heat alone and without the use of radiation.
Using the pre-clinical data from Massachusetts General, the FDA


                                       5



granted Celsion a supplemental premarketing approval to incorporate the APA
technology with Celsion's already approved Microfocus 1000 system. The APA
technology enhances the ability of the Microfocus 1000 system to focus energy.

         In January 1999, we received an IDE from the FDA to permit clinical
testing of our breast cancer treatment system, and also received FDA approval to
proceed with Phase I human clinical studies. In August 2000, we completed the
treatment of ten patients in the Phase I study using our breast cancer equipment
at Columbia Hospital in West Palm Beach, Florida, and at Harbor UCLA Medical
Center in Torrance, California. In the study, our equipment was clinically
tested on female breast tumors on a minimally invasive basis through a single
application of precisely controlled and targeted heat. In December 2000, we
received approval from the FDA to commence Phase II trials for our breast cancer
system.

         The Phase II trials consist of two protocols--the first is designed to
ablate (kill) small breast tumors including microscopic lesions in the margin of
the tumor, leaving the margins clear of viable cancer cells using heat alone and
the second is designed to downsize large breast cancer tumors using a
combination of heat and chemotherapy, thus allowing a surgeon to perform a
lumpectomy rather than a mastectomy, thereby preserving the affected breast.
These trials are currently under way at St. Joseph's Hospital Breast Center in
Orange, California, Harbor-UCLA Medical Center in Torrance, California, the
University of Oklahoma at Oklahoma City, Comprehensive Breast Center of Coral
Springs in Coral Springs, Florida, Mroz-Baier Breast Care Center in Memphis,
Tennessee, Lynne Clark, M.D. in Tacoma, Washington, Breast Care Specialists in
Norfolk, Virginia, and Bolton Breast Unit.

         Effective May 25, 2004, we suspended both branches of our pivotal Phase
II trials using the Company's advanced phase array microwave technology in the
treatment of small and late stage breast cancer tumors. The decision to suspend
was taken after preliminary evaluation of interim (midpoint) data from the
trials. In the small tumor study, the Company determined that it was achieving
the primary endpoint of reducing second incisions, but that it was not
consistently meeting its secondary endpoint of reducing tumor burden as measured
by tumor necrosis. The Company believes that these inconsistent results may be
due to inconsistent delivery of an adequate thermal dose. In the late-stage
study, the Company was encountering difficulties in enrolling sufficient
patients in part due to a change in the prevailing standard of care specified in
the study protocol and in part due to a shortage of late-stage tumor patients,
due to earlier detection of breast cancer.



THERMODOX(TM) (DOXORUBICIN ENCAPSULATED IN HEAT-ACTIVATED LIPOSOME); DUKE
UNIVERSITY

         BACKGROUND

         Liposomes are man-made microscopic spheres with a liquid membrane,
developed in the 1980's to encapsulate drugs for targeted delivery. Commercial
liposomes can now encapsulate chemotherapeutic drugs, enabling them to avoid
destruction by the body's immune system, and allowing them to accumulate in
tumors. However, with presently available technology, it often takes two to four
hours for commercial liposomes to release their drug contents to the tumors,
severely limiting the clinical efficacy of liposome chemotherapy treatments.

         DEVELOPMENT OF THERMO-SENSITIVE LIPOSOMES

         A team of Duke University scientists has developed heat-sensitive
liposomes comprised of materials that rapidly change porosity when heated to a
specific point. As the heat-sensitive liposomes circulate within the small
arteries, arterioles, and capillaries, the drug contents of the liposomes are
released at significantly higher levels in those tissue areas that have been
heated for 30 to 60 minutes than in areas that do not receive heat. In animal
trials it has been determined that 50 times the amount of drugs carried by
heat-sensitive liposomes was deposited at a specific heated tissue site, when
compared to conventional liposomes. We have been a sponsor of this research,
which is part of a larger Duke University project to develop new
temperature-sensitive liposomes, temperature-sensitive gene promoters and
related compounds, and we are the exclusive licensee of Duke University's
heat-activated liposome technology.

         Celsion's focused microwave equipment is used to provide minimally
invasive heating of cancerous tumors to trigger heat-activated liposomes within
the tumors. The heat-activated liposomes, which encapsulate chemotherapeutic
agents, are injected into the bloodstream where they remain encapsulated until
they release their drug payload inside the heated tumor. In preliminary tumor
growth delay studies conducted at Duke University, tumor-bearing mice received a
single intravenous injection of the liposome with a 5 mg per kilogram
Doxorubicin concentration. This was immediately followed by heating of the tumor
to 42(degree) C (108(degree) F) for one hour. The result of the study was a
complete regression of the tumors in 11 out of 11 mice. These animals remained
disease free through 60 days of the study.

         In November 2001, we completed large animal toxicity studies involving
ThermoDox(TM), our Doxorubicin-laden thermo-liposome, at the Roswell Park Cancer
Institute, a cancer research organization in Buffalo, New York, and at Dartmouth
Hitchcock Medical Center, a teaching hospital associated with Dartmouth Medical
College. In March 2002, we filed an Investigational New Drug, or IND,
application with the FDA for the use of ThermoDox in the treatment of prostate
cancer using our Prolieve equipment as the means of heat-activation. The IND
became effective in June 2002 and we have had a Phase I clinical trial underway
at Roswell Park and Regional Urology in Shreveport, Louisiana.


                                       6



         In addition, in January 2001, we entered into a Material Transfer
Agreement, or MTA, with the National Cancer Institute, or NCI, under which we
are supplying ThermoDox to enable the NCI to conduct clinical trials on liver
cancer. NCI is using an RF heating device to ablate the tumors and to heat the
liver, activating ThermoDox to kill peripheral cancer cells. Liver cancer has
yet to be successfully treated with existing treatment modalities. NCI is
currently completing pre-clinical studies and we filed an IND for the treatment
of liver cancer on December 22, 2003.

         Celsion's focused microwave equipment is used to provide minimally
invasive heating of cancerous tumors to trigger heat-activated liposomes within
the tumors. The heat-activated liposomes, which encapsulate chemotherapeutic
agents, are injected into the bloodstream where they remain encapsulated until
they release their drug payload inside the heated tumor. In preliminary tumor
growth delay studies conducted at Duke University, tumor-bearing mice received a
single intravenous injection of the liposome with a 5 mg per kilogram
Doxorubicin concentration. This was immediately followed by heating of the tumor
to 42(degree) C (108(degree) F) for one hour. The result of the study was a
complete disappearance of the tumors in 11 out of 11 mice. These animals
remained disease free through 60 days of the study.

         In November 2001, we completed large animal toxicity studies involving
Thermodox(TM), our Doxorubicin-laden thermo-liposome at the Roswell Park Cancer
Institute, a cancer research organization in Buffalo, New York and at Dartmouth
Hitchcock Medical Center, a teaching hospital associated with Dartmouth Medical
College. In March 2002, we filed an IND application with the FDA for the use of
Thermodox(TM) in the treatment of prostate cancer using our Prolieve equipment
as the means of heat activation. The IND became effective in June 2002 and we
have had a Phase I clinical trial underway at Roswell Park and Regional Urology
in Shreveport, Louisiana since May 28, 2003.

         In addition, in January 2001, we entered into a Material Transfer
Agreement (MTA) with the National Cancer Institute, or NCI, under which we are
supplying heat-activated liposomes to enable the NCI to conduct clinical trials
on liver cancer. NCI is using an RF heating device to isolate the tumors and to
heat the liver, activating Celsion's heat-activated liposomes to kill peripheral
cancer cells. Liver cancer has yet to be successfully treated with existing
treatment modalities. NCI is currently completing preclinical studies and we
hope to file an IND for the treatment of liver cancer early in 2004.

         Celsion and Duke University are pursuing further development work and
pre-clinical studies aimed at using the new thermo-liposome technology in
conjunction with our APA focused heat technology for a variety of applications,
including cancer chemotherapy. We view the Duke thermo-liposome technology as a
highly promising improvement in the delivery of medicines used to combat serious
diseases. For example, the drugs used to fight cancer in chemotherapy regimens
are often toxic when administered in large quantities, and produce nausea,
vomiting, and exhaustion- all side effects of the body being poisoned. However,
if such a drug can be delivered directly to a tissue area where it is needed, as
opposed to being distributed through the entire circulatory system, the local
concentration of the drug could be increased without the side effects that
accompany large systemic dosing.

         In addition, in the July 1, 2000 issue of Cancer Research, a Duke
University research scientist reported on his initial use of heat to activate
gene therapy and to increase the production in animals of Interleukin-12, a
genetic protein, in order to delay tumor growth. On August 8, 2000, we entered
into an agreement with Duke University, subsequently renewed for six-month
periods, under which Celsion has the right, for a period of six months
thereafter, to negotiate an exclusive license for this technology.

         ALLIED TECHNOLOGY

         On July 18, 2003, we entered into an additional license agreement with
Duke, pursuant to which we have obtained exclusive rights to an advanced phased
array radio frequency heating system designed specifically for use with
chemotherapeutic drugs for the treatment of locally advanced breast cancer. The
system, developed by Duke engineers, uses RF energy to warm a woman's breast to
approximately 42(degree) C to enhance the effectiveness of liposomal
chemotherapeutic compounds. During the treatment, the breast is immersed in a
pool of distilled water, which helps distribute the heat evenly around the
breast, thus preventing skin burns and "hot spots," which often create pain.
Skin burns and hot spots have, up to now, limited the use of RF hyperthermia as
an effective means for treatment of breast cancer.

         This heating system is currently being clinically evaluated at Duke. A
Phase I trial has been completed and a Phase II trial is underway. The
combination of trials was designed to demonstrate the system's ability to
enhance the combined therapeutic effect of liposomal encapsulations of
Doxorubicin(R) plus traditional paclitaxel (Taxol(R)) in the management of
locally advanced breast cancer. Results of the Phase I study, which included 21
women, indicated that tumor growth was halted in all of the women participating
in the trial and that 50% of the treated tumors were reduced in size. Eleven
percent of the trial participants had complete pathologic


                                       7



responses, meaning no cancer was found in the breast tissue upon analyzing its
surgical remains, and 33% of patients had complete clinical responses, meaning
visible signs of the tumor could no longer be detected. An additional 17% of
trial participants were converted from mastectomy candidates to lumpectomy
candidates. Celsion intends to work with Duke University staff to explore the
potential for using this heating system in combination with ThermoDox to treat
breast cancer.

PRODUCTION OF HEAT-SENSITIVE LIPOSOMES

         We have established a relationship with Celator Corporation of
Vancouver, Canada to provide Quality System Regulation, or QSR (formerly Good
Manufacturing Practices, or GMP), production of our heat-activated liposome for
our completed large animal toxicity studies and our planned Phase I clinical
study in humans. Celator is a leading drug formulation and discovery company
that specializes in liposome drug development. In November 2002, Celsion engaged
Northern Lipids Limited, a Vancouver, Canada-based liposome consulting firm, to
develop a scaled-up manufacturing process for this product and, in September
2003, we engaged Baxter Pharmaceuticals to produce the liposomes on a commercial
scale.

SLOAN-KETTERING / CELSION HEAT-ACTIVATED GENE THERAPY COMPOUNDS

         BACKGROUND

         Cancer cells have the ability to repair themselves after radiation or
chemotherapy. Thus, patients require repeated treatments to destroy
substantially all of the cancer cells. Celsion has licensed from Sloan-Kettering
Cancer Center, a biomedical innovation that promises significant improvements in
cancer therapy. Sloan-Kettering has developed biological modifiers that inhibit
cancer cells' ability to repair themselves. Activated by focused heat, this
Cancer Repair Inhibitor, or CRI, temporarily disables the repair mechanism of
cancer cells, making it possible to reduce significantly the number of
radiation/chemotherapy treatments and/or lower the treatment dosage.

         A standard approach to treating cancer is radiation therapy combined
with chemotherapy. High doses of radiation kill cancer cells or keep them from
dividing, but produce chronic or acute side effects, including fatigue,
neutropenia, anemia and leukopenia. Also, depending on the location of the
tumor, other acute side effects may occur, including diarrhea, allopecia and
various foreign ulcers. Chemotherapy presents comparable or more serious side
effects.

         Oncologists are looking for ways to mitigate these side effects. In
radiation therapy, these include hyperfractionated radiation, intra-operative
radiation, three-dimensional radiation, stereotactic radiosurgery and the use of
radio-labeled monoclonal antibodies and radio sensitizers. CRI falls into this
latter category because it "sensitizes" a cancer cell for treatment by making it
more susceptible to DNA-damaging agents such as heat, chemicals or radiation. A
product of advances in the understanding of the biology of cancer, CRI is one of
a new class of "biologics" that are expected to become part of the cancer
treatment protocol.

         THE CELSION TECHNOLOGY--CRI PLUS FOCUSED HEAT

         CRI can be activated in tumors by minimally invasive focused heat in
the range of 41(degree) C (106(degree) F). This focused heat may be generated by
Celsion's Adaptive Phased Array microwave technology or other heating systems.
Having increased the susceptibility of cancer cells to DNA-damaging agents,
radiation and chemotherapy treatment may then be administered with less
frequency and/or at lower doses than currently is possible. CRI would then
deactivate and the patient would resume normal post-treatment care.

         In September 2001, scientists at Sloan-Kettering successfully completed
pre-clinical laboratory feasibility demonstrations to assess safety and
biological activity of CRI. In December 2001, a small animal feasibility study
was completed at Sloan-Kettering's Good Laboratory Practice (GLP) facility to
assist in drug formulation. Further studies with large animals to assess
toxicity effects are expected to be conducted. Following completion of these
toxicity studies, the Company expects to file an IND.

         In May 2000, we entered into an exclusive worldwide agreement with
Sloan-Kettering for the commercial rights to the heat-activated gene therapy
technology developed by Sloan-Kettering. In the June 15, 2003 issue of Cancer
Research, a Sloan-Kettering scientist summarized the scientific and clinical
rationale leading to the successful development of the heat-activated anti-sense
genetic modifier and the pre-clinical evaluations, which demonstrated the
feasibility of its use as a potent radiation sensitizer for the treatment of
cancer.

         In addition, in the July 1, 2000 issue of Cancer Research, a Duke
University research scientist reported on his initial use of heat to activate
gene therapy and to increase the production in animals of Interleukin-12, a
genetic protein, in order to delay tumor


                                       8



growth. On August 8, 2000, we entered into an agreement with Duke University,
subsequently renewed for consecutive six-month periods, under which Celsion has
the right, for a period of six months thereafter, to negotiate an exclusive
license for this technology.

                                  RISK FACTORS

         You should carefully consider the risks described below before making a
decision to invest in our Common Stock. You should also refer to the other
information in this Prospectus, as well as the information incorporated by
reference into this Prospectus, including our financial statements and the
related notes. The risks and uncertainties described below are not the only ones
that could affect our Company. Additional risks and uncertainties of which we
are unaware or that we currently believe are immaterial also may become
important factors affecting our business. If any one or more of the following
risks occur, our business, results of operations and financial condition could
be materially harmed. As a result, the trading price of our Common Stock could
decline, and you could lose all or part of your investment. The terms the
"Company," "we," "us" and "our" used throughout this Prospectus all refer to
Celsion Corporation.

         WE HAVE A HISTORY OF SIGNIFICANT LOSSES AND EXPECT TO CONTINUE SUCH
LOSSES FOR THE FORESEEABLE FUTURE.

         Since Celsion's inception in 1982, our expenses have substantially
exceeded our revenues, resulting in continuing losses and an accumulated deficit
of $66,297,896 at March 31, 2004, including losses of $14,293,081 for the 12
months ended December 31, 2003 and $6,065,680 for the quarter ended March 31,
2004. Because we presently have only limited revenues and are committed to
continuing our product research, development and commercialization programs, we
will continue to experience significant operating losses unless and until we
complete the development of new products and these products have been clinically
tested, approved by the FDA and successfully marketed. In addition, we have
funded our operations for many years primarily through the sale of the Company's
securities and have limited working capital for our product research,
development, commercialization and other activities.

WE DO NOT EXPECT TO GENERATE SIGNIFICANT REVENUE FOR THE FORESEEABLE FUTURE.

         Since 1995 we have devoted our resources to developing a new generation
of thermotherapy and other products, but are not able to market these products
unless and until we complete clinical testing and obtain all necessary
governmental approvals. On February 19, 2004, we received a PMA from the FDA for
the first of our new generation of thermotherapy products--our Prolieve
Thermodilatation system for the treatment of BPH--and, since that time, our
distributor Boston Scientific has begun commercial introduction of the Prolieve
system. However, we can give no assurance as to how much revenue, if any, will
be generated by Prolieve sales or when sales of Prolieve systems may occur. In
addition, at the present time our other products are still in various stages of
development and testing and cannot be marketed until we have completed clinical
testing and obtained necessary governmental approval. Accordingly, current
revenue sources to sustain our operations are extremely limited and will remain
so until and unless our Prolieve system is marked successfully and/or until our
other new products are clinically tested, approved by the FDA and successfully
marketed. We cannot guarantee that any or all of our products will be
successfully tested, approved by the FDA or marketed, successfully or otherwise,
at any time in the foreseeable future or at all.

SOME OF OUR TECHNOLOGY IS STILL UNDERGOING CLINICAL TESTING; OUR TECHNOLOGIES
MAY NOT ACHIEVE SUFFICIENT ACCEPTANCE BY THE MEDICAL COMMUNITY TO SUSTAIN OUR
BUSINESS.

         To date, microwave heat therapy has not been widely accepted in the
United States medical community as an effective treatment for BPH or for cancer
treatment, with or without the concurrent use of radiation. We believe that this
is primarily due to the inability of earlier technology adequately to focus and
control heat directed at specific tissue locations and to conclusions that were
drawn from a widely publicized study by the Radiation Oncology Therapy Group
that purported to show that thermotherapy in conjunction with radiation was only
marginally effective. Subsequent to the publication of this study, the
HealthCare Financing Administration, or HCFA (now known as the Centers for
Medicare and Medicaid Services, or CMS) established a low medical reimbursement
rate for all thermotherapy equipment designed to be used in conjunction with
radiation. While management believes that our new technology is capable of
overcoming the limitations of the earlier technology, the medical community may
not embrace the perceived advantages of our "Adaptive Phased Array," or APA,
focused heat therapy without more extensive testing and clinical experience than
we will be able to provide. To date, we have received a PMA from the FDA for our
Prolieve system for the treatment of BPH, but we can offer no assurance that the
Prolieve system will be accepted by the medical community widely or at all. Our
new cancer treatment technology is currently in Phase II trials. This technology
may not prove as effective in practice as we on anticipate. If further testing
and clinical practice do not confirm the safety and efficacy of our technology
or, even if further testing and practice produce positive results but the
medical community does not view this new form of heat therapy as effective and
desirable, our efforts


                                       9



to market our new products may fail, with material adverse consequences to our
business. We intend to petition CMS for a new reimbursement code for our breast
cancer treatment. The success of our business model depends significantly upon
our ability to petition successfully for reimbursement codes. However, we cannot
offer any assurances as to when, if ever, CMS may act on our request to
establish a reimbursement code for our breast cancer treatment system. In
addition, there can be no assurance that the reimbursement level established for
our breast cancer treatment system, if established, will be sufficient for us to
carry out our business plan effectively.

IF WE ARE NOT ABLE TO OBTAIN NECESSARY FUNDING, WE WILL NOT BE ABLE TO COMPLETE
THE DEVELOPMENT, TESTING AND COMMERCIALIZATION OF OUR TREATMENTS AND PRODUCTS.

         We will need substantial additional funding in order to complete the
development, testing and commercialization of our breast cancer treatment system
and heat-activated liposome and cancer repair inhibitor products, as well as
other potential new products. We expended approximately $14,333,740 in the
12-month period ended December 31, 2003 and an additional $6,155,472 in the
three months ended March 31, 2004. As of that date, we had available a total of
approximately $19,426,771 to fund our operations. We have both increased the
pace of development work on our present products and made a significant
commitment to our heat-activated liposome and cancer repair inhibitor research
and development projects and it is our intention to at least maintain, or
increase the pace and scope of these activities. The increase in the scope of
present development work and the commitment to these new projects will require
additional external funding, at least until we are able to generate sufficient
cash flow from sale of one or more of our products to support our continued
operations. We do not have any committed sources of financing and cannot offer
any assurances that additional funding will be available in a timely manner, on
acceptable terms or at all.

         If adequate funding is not available, we may be required to delay,
scale back or eliminate certain aspects of our operations or attempt to obtain
funds through unfavorable arrangements with partners or others that may force us
to relinquish rights to certain of our technologies, products or potential
markets or that could impose onerous financial or other terms. Furthermore, if
we cannot fund our ongoing development and other operating requirements,
particularly those associated with our obligations to conduct clinical trials
under our licensing agreements, we will be in breach of these licensing
agreements and could therefore lose our license rights, which could have
material adverse effects on our business.

OUR BUSINESS IS SUBJECT TO NUMEROUS AND EVOLVING STATE, FEDERAL AND FOREIGN
REGULATIONS AND WE MAY NOT BE ABLE TO SECURE THE GOVERNMENT APPROVALS NEEDED TO
DEVELOP AND MARKET OUR PRODUCTS.

         Our research and development activities, pre-clinical tests and
clinical trials, and ultimately the manufacturing, marketing and labeling of our
products, all are subject to extensive regulation by the FDA and foreign
regulatory agencies. Pre-clinical testing and clinical trial requirements and
the regulatory approval process typically take years and require the expenditure
of substantial resources. Additional government regulation may be established
that could prevent or delay regulatory approval of our product candidates.
Delays or rejections in obtaining regulatory approvals would adversely affect
our ability to commercialize any product candidates and our ability to generate
product revenues or royalties.

         The FDA and foreign regulatory agencies require that the safety and
efficacy of product candidates be supported through adequate and well-controlled
clinical trials. If the results of pivotal clinical trials do not establish the
safety and efficacy of our product candidates to the satisfaction of the FDA and
other foreign regulatory agencies, we will not receive the approvals necessary
to market such product candidates.

         Even if regulatory approval of a product candidate is granted, the
approval may include significant limitations on the indicated uses for which the
product may be marketed. In addition, manufacturing establishments in the United
States and abroad are subject to inspections and regulations by the FDA. Medical
devices must also continue to comply with the FDA's Quality System Regulation,
or QSR. Compliance with such regulations requires significant expenditures of
time and effort to ensure full technical compliance. The FDA stringently applies
regulatory standards for manufacturing.

         We are also subject to record keeping and reporting regulations,
including FDA's mandatory Medical Device Reporting, or MDR regulation. Labeling
and promotional activities are regulated by the FDA and, in certain instances,
by the Federal Trade Commission.


                                       10



         Many states in which we do or in the future may do business or in which
our products may be sold impose licensing, labeling or certification
requirements that are in addition to those imposed by the FDA. There can be no
assurance that one or more states will not impose regulations or requirements
that have a material adverse effect on our ability to sell our products.

         In many of the foreign countries in which we may do business or in
which our products may be sold, we will be subject to regulation by national
governments and supranational agencies as well as by local agencies affecting,
among other things, product standards, packaging requirements, labeling
requirements, import restrictions, tariff regulations, duties and tax
requirements. There can be no assurance that one or more countries or agencies
will not impose regulations or requirements that could have a material adverse
effect on our ability to sell our products.

         The EU has a registration process that includes registration of
manufacturing facilities (known as "ISO certification") and product
certification (known as a "CE Mark"). We have obtained ISO certification for our
existing facilities. However, there is no guarantee that we will be successful
in obtaining European certifications for new facilities or for our products, or
that we will be able to maintain its existing certifications in the future.

         Foreign government regulation may delay marketing of our new products
for a considerable period of time, impose costly procedures upon its activities
and provide an advantage to larger companies that compete with it. There can be
no assurance that we will be able to obtain necessary regulatory approvals, on a
timely basis or at all, for any products that it develops. Any delay in
obtaining, or failure to obtain, necessary approvals would materially and
adversely affect the marketing of our contemplated products subject to such
approvals and, therefore, our ability to generate revenue from such products.

         Even if regulatory authorities approve our product candidates, such
products and our facilities, including facilities located outside the EU, may be
subject to ongoing testing, review and inspections by the European health
regulatory authorities. After receiving premarketing approval, in order to
manufacture and market any of its products, we will have to comply with
regulations and requirements governing manufacture, labeling and advertising on
an ongoing basis.

         Failure to comply with applicable domestic and foreign regulatory
requirements, can result in, among other things, warning letters, fines,
injunctions and other equitable remedies, civil penalties, recall or seizure of
products, total or partial suspension of production, refusal of the government
to grant approvals, pre-market clearance or pre-market approval, withdrawal of
approvals and criminal prosecution of the Company and its employees, all of
which would have a material adverse effect on our business.

OUR BUSINESS DEPENDS ON LICENSE AGREEMENTS WITH THIRD PARTIES TO PERMIT US TO
USE PATENTED TECHNOLOGIES. THE LOSS OF ANY OF OUR RIGHTS UNDER THESE AGREEMENTS
COULD IMPAIR OUR ABILITY TO DEVELOP AND MARKET OUR PRODUCTS.

         Currently, we have three utility patents pending in the United States
Patent & Trademark Office. Two are directed to our Prolieve system for the
treatment of BPH and the other is directed to our breast cancer treatment
system. However, even when our pending applications mature into United States
patents, our business will still depend on license agreements that it has
entered into with third parties until the third parties' patents expire.

         Our success will depend, in substantial part, on our ability to
maintain our rights under license agreements granting us rights to use patented
technologies. We have entered into exclusive license agreements with MIT, for
APA technology and with MMTC, a privately owned developer of medical devices,
for microwave balloon catheter technology. We have also entered into a license
agreement with Duke University, under which we have exclusive rights to
commercialize medical treatment products and procedures based on Duke
University's thermo-liposome technology, an advanced phased array radio
frequency (RF) heating system designed specifically for use with
chemotherapeutic drugs for the treatment of locally advanced breast cancer and a
license agreement with Memorial Sloan-Kettering Cancer Center under which we
have rights to commercialize certain cancer repair inhibitor products. The MIT,
MMTC, Duke University and Sloan-Kettering agreements each contain license fee,
royalty and/or research support provisions, testing and regulatory milestones,
and other performance requirements that we must meet by certain deadlines. If we
were to breach these or other provisions of the license and research agreements,
we could lose our ability to use the subject technology, as well as compensation
for our efforts in developing or exploiting the technology. Further, loss of our
rights under the MIT license agreement would prevent us from proceeding with
most our current product development efforts, which are dependent on licensed
APA technology. Any such loss of rights and access to technology would have a
material adverse effect on our business.

         Further, we cannot guarantee that any patent or other technology rights
licensed to us by others will not be challenged or circumvented successfully by
third parties, or that the rights granted will provide adequate protection. We
are aware of published


                                       11



patent applications and issued patents belonging to others, and it is not clear
whether any of these patents or applications, or other patent applications of
which it may not have any knowledge, will require us to alter any of our
potential products or processes, pay licensing fees to others or cease certain
activities. Litigation, which could result in substantial costs, may also be
necessary to enforce any patents issued to or licensed by us or to determine the
scope and validity of others' claimed proprietary rights. We also rely on trade
secrets and confidential information that we seek to protect, in part, by
confidentiality agreements with our corporate partners, collaborators, employees
and consultants. We cannot guarantee that these agreements will not be breached,
that, even if not breached, that they are adequate to protect our trade secrets,
that we will have adequate remedies for any breach or that our trade secrets
will not otherwise become known to, or will not be discovered independently by,
competitors.

TECHNOLOGIES FOR THE TREATMENT OF CANCER ARE SUBJECT TO RAPID CHANGE AND THE
DEVELOPMENT OF TREATMENT STRATEGIES THAT ARE MORE EFFECTIVE THAN OUR
THERMOTHERAPY TECHNOLOGY COULD RENDER OUR TECHNOLOGY OBSOLETE.

         Various methods for treating cancer currently are, and in the future
may be expected to be, the subject of extensive research and development. Many
possible treatments that are being researched, if successfully developed, may
not require, or may supplant, the use of our thermotherapy technology. These
alternate treatment strategies include the use of radio frequency (RF), laser
and ultrasound energy sources. The successful development and acceptance of any
one or more of these alternative forms of treatment could render our technology
obsolete as a cancer treatment method.

WE MAY NOT BE ABLE TO HIRE OR RETAIN KEY OFFICERS OR EMPLOYEES THAT WE NEED TO
IMPLEMENT ITS BUSINESS STRATEGY AND DEVELOP ITS PRODUCTS AND BUSINESSES.

         Our success depends significantly on the continued contributions of our
executive officers, scientific and technical personnel and consultants, and on
our ability to attract additional personnel as we seek to implement our business
strategy and develop our products and businesses. During our operating history,
we have assigned many essential responsibilities to a relatively small number of
individuals. However, as our business and the demands on our key employees
expand, we have been, and will continue to be, required to recruit additional
qualified employees. The competition for such qualified personnel is intense,
and the loss of services of certain key personnel or our inability to attract
additional personnel to fill critical positions as we implement our business
strategy could adversely affect our business. Further, we do not carry "key man"
insurance on any of our personnel. Therefore, loss of the services of key
personnel would not be ameliorated by the receipt of the proceeds from such
insurance.

OUR SUCCESS WILL DEPEND IN PART ON OUR ABILITY TO GROW AND DIVERSIFY, WHICH IN
TURN WILL REQUIRE THAT WE MANAGE AND CONTROL OUR GROWTH EFFECTIVELY.

         Our business strategy contemplates growth and diversification. As
manufacturing, marketing, sales, and other personnel, and expand our
manufacturing and research and development capabilities we add, our operating
expenses and capital requirements will increase. Our ability to manage growth
effectively will require that we continue to expend funds to improve our
operational, financial and management controls, reporting systems and
procedures. In addition, we must effectively expand, train and manage our
employees. We will be unable to manage our businesses effectively if we are
unable to alleviate the strain on resources caused by growth in a timely and
successful manner. There can be no assurance that we will be able to manage our
growth and a failure to do so could have a material adverse effect on our
business.

THE SUCCESS OF OUR PRODUCTS MAY BE HARMED IF THE GOVERNMENT, PRIVATE HEALTH
INSURERS AND OTHER THIRD- PARTY PAYORS DO NOT PROVIDE SUFFICIENT COVERAGE OR
REIMBURSEMENT.

         Our ability to commercialize our thermotherapy technology successfully
will depend in part on the extent to which reimbursement for the costs of such
products and related treatments will be available from government health
administration authorities, private health insurers and other third-party
payors. The reimbursement status of newly approved medical products is subject
to significant uncertainty. We cannot guarantee that adequate third-party
insurance coverage will be available for us to establish and maintain price
levels sufficient for us to realize an appropriate return on our investment in
developing new therapies. Government, private health insurers and other
third-party payors are increasingly attempting to contain health care costs by
limiting both coverage and the level of reimbursement for new therapeutic
products approved for marketing by the FDA. Accordingly, even if coverage and
reimbursement are provided by government, private health insurers and
third-party payors for uses of our products, market acceptance of these products
would be adversely affected if the reimbursement available proves to be
unprofitable for health care providers.


                                       12



WE FACE INTENSE COMPETITION AND THE FAILURE TO COMPETE EFFECTIVELY COULD
ADVERSELY AFFECT OUR ABILITY TO DEVELOP AND MARKET OUR PRODUCTS.

         There are many companies and other institutions engaged in research and
development of thermotherapy technologies, both for prostate disease and cancer
treatment products that seek treatment outcomes similar to those that we are
pursuing. In addition, a number of companies and other institutions are pursuing
alternative treatment strategies through the use of microwave, infrared, radio
frequency, laser and ultrasound energy sources, all of which appear to be in the
early stages of development and testing. We believe that the level of interest
by others in investigating the potential of thermotherapy and alternative
technologies will continue and may increase. Potential competitors engaged in
all areas of prostate and cancer treatment research in the United States and
other countries include, among others, major pharmaceutical and chemical
companies, specialized technology companies, and universities and other research
institutions. Most of our competitors and potential competitors have
substantially greater financial, technical, human and other resources, and may
also have far greater experience, than do we, both in pre-clinical testing and
human clinical trials of new products and in obtaining FDA and other regulatory
approvals. One or more of these companies or institutions could succeed in
developing products or other technologies that are more effective than the
products and technologies that we have been or are developing, or which would
render our technology and products obsolete and non-competitive. Furthermore, if
we are permitted to commence commercial sales of any of our products, we will
also be competing, with respect to manufacturing efficiency and marketing, with
companies having substantially greater resources and experience in these areas.

LEGISLATIVE AND REGULATORY CHANGES AFFECTING THE HEALTH CARE INDUSTRY COULD
ADVERSELY AFFECT OUR BUSINESS.

         There have been a number of federal and state proposals during the last
few years to subject the pricing of health care goods and services to government
control and to make other changes to the United States health care system. It is
uncertain which legislative proposals, if any, will be adopted (or when) or what
actions federal, state, or private payors for health care treatment and services
may take in response to any health care reform proposals or legislation. We
cannot predict the effect health care reforms may have on our business and we
can offer no assurances that any of these reforms will not have a material
adverse effect on that business.

WE MAY BE SUBJECT TO SIGNIFICANT PRODUCT LIABILITY CLAIMS AND LITIGATION.

         Our business exposes us to potential product liability risks inherent
in the testing, manufacturing and marketing of human therapeutic products. We
presently have product liability insurance limited to $5,000,000 per incident.
If we were to be subject to a claim in excess of this coverage or to a claim not
covered by our insurance and the claim succeeded, we would be required to pay
the claim with our own limited resources, which could have a material adverse
effect on our business. In addition, liability or alleged liability could harm
the business by diverting the attention and resources of our management and by
damaging our reputation.

WE PRESENTLY HAVE LIMITED MARKETING AND SALES CAPABILITY AND WILL BE REQUIRED TO
DEVELOP SUCH CAPABILITIES AND TO ENTER INTO ALLIANCES WITH OTHERS POSSESSING
SUCH CAPABILITIES IN ORDER TO COMMERCIALIZE OUR PRODUCTS SUCCESSFULLY.

         We have begun to commercialize and market our Prolieve Thermodilatation
system through Boston Scientific. Consequently, we are dependent upon Boston
Scientific for the successful introduction and marketing of our Prolieve system.
There can be no assurance that Boston Scientific will establish adequate sales
and distribution capabilities or be successful in gaining market acceptance for
Prolieve system. We intend to market our other products, if and when such
products are approved for commercialization by the FDA, through other strategic
alliances and distribution arrangements with third parties. There can be no
assurance that we will be able to establish such sales and marketing
capabilities successfully or successfully enter into third-party marketing or
distribution arrangements and, to the extent that we do enter into such
arrangements, we will be dependent, to some degree, on our marketing and
distribution partners. We have limited experience and capabilities in marketing,
distribution and direct sales, although we expect to attempt to recruit
experienced marketing and sales personnel as we pursue commercialization. In
attracting, establishing and maintaining a marketing and sales force or entering
into third-party marketing or distribution arrangements with other companies, we
expect to incur significant additional expense. There can be no assurance that,
to the extent we enter into any commercialization arrangements with third
parties as and when our other products or services receive FDA approval, such
third parties will establish adequate sales and distribution capabilities or be
successful in gaining market acceptance for our products and services. There
also can be no assurance that our direct sales, marketing, licensing and
distribution efforts would be successful or that revenue from such efforts would
exceed expenses.


                                       13



WE DEPEND ON THIRD-PARTY SUPPLIERS TO PROVIDE US WITH COMPONENTS REQUIRED FOR
OUR PRODUCTS AND MAY NOT BE ABLE TO OBTAIN THESE COMPONENTS ON FAVORABLE TERMS
OR AT ALL.

         We are not currently manufacturing any products, but are using our
facilities to assemble prototypes of the equipment for research and development
purposes. We currently purchase certain specialized microwave and thermometry
components and applicator materials and the catheter unit used for our clinical
trial products from single or limited source suppliers because of the small
quantities involved. While we have not experienced any significant difficulties
in obtaining these components, the loss of an important current supplier could
require that we obtain a replacement supplier, which could result in delays and
additional expense in being able to make prototype equipment available for
clinical trials and other research purposes. For our Prolieve equipment, we use
outside contractors to manufacture finished equipment and the disposable
catheter kit used in conjunction with the equipment. In turn, these suppliers
are dependent on single source and other components suppliers. Although we
believe that alternative sources of supply would be available if the need arose,
the loss of one or more of these suppliers would require that we obtain a
replacement source, which could result in delays and additional expense to
redesign the product to accept the replacement vendor.

WE HAVE NOT PAID DIVIDENDS IN THE PAST AND DO NOT INTEND TO DO SO FOR THE
FORESEEABLE FUTURE.

         We have never paid cash dividends and do not anticipate paying cash
dividends on our common or preferred stock in the foreseeable future. Therefore,
our stockholders cannot achieve any degree of liquidity with respect to their
shares of Common Stock except by selling such shares.

THE EXERCISE OF OUR OUTSTANDING OPTIONS AND WARRANTS COULD RESULT IN SIGNIFICANT
DILUTION OF OWNERSHIP INTERESTS IN OUR COMMON STOCK OR OTHER CONVERTIBLE
SECURITIES.

         As of April 30, 2004, we had outstanding and exercisable warrants and
options to purchase a total of 23,724,677 shares of our Common Stock at exercise
prices ranging from $0.25 to $5.00 per share (with a weighted average exercise
price of approximately $0.89 per share). In addition, we had outstanding but
unexercisable and unvested warrants and options to purchase a total of 1,965,000
shares of our Common Stock at exercise prices ranging from $0.40 to $1.50 per
share (with a weighted average exercise price of approximately $0.85 per share).
Some of the prices are below the current market price of our Common Stock, which
has ranged from a low of $1.04 to a high of $1.26 over the 20 trading days
ending April 30, 2004. If holders choose to exercise such warrants and options
at prices below the prevailing market price for the Common Stock, the resulting
purchase of a substantial number of shares of our Common would have a dilutive
effect on our stockholders and could adversely affect the market price of our
issued and outstanding Common Stock and convertible securities. In addition,
holders of these options and warrants who have the right to require registration
of the Common Stock under certain circumstances and who elect to require such
registration, or who exercise their options or warrants and then satisfy the
one-year holding period and other requirements of Rule 144 of the Securities
Act, will be able to sell in the public market shares of Common Stock purchased
upon such exercise.

IF THE PRICE OF OUR SHARES REMAINS LOW, WE MAY BE DELISTED BY THE AMERICAN STOCK
EXCHANGE AND BECOME SUBJECT TO SPECIAL RULES APPLICABLE TO LOW PRICED STOCKS

         Our Common Stock currently trades on The American Stock Exchange (the
Amex). The Amex, as a matter of policy, will consider the suspension of trading
in, or removal from listing of, any stock when, in the opinion of the Amex, (i)
the financial condition and/or operating results of an issuer appear to be
unsatisfactory; (ii) it appears that the extent of public distribution or the
aggregate market value of the stock has become so reduced as to make further
dealings on the Amex inadvisable; (iii) the issuer has sold or otherwise
disposed of its principal operating assets; or (iv) the issuer has sustained
losses which are so substantial in relation to its overall operations or its
existing financial condition has become so impaired that it appears
questionable, in the opinion of the Amex, whether the issuer will be able to
continue operations and/or meet its obligations as they mature. For example, the
Amex will consider suspending dealings in or delisting the stock of an issuer if
the issuer has sustained losses from continuing operations and/or net losses in
its five most recent fiscal years. Another instance where the Amex would
consider suspension or delisting of a stock is if the stock has been selling for
a substantial period of time at a low price per share and the issuer fails to
effect a reverse split of such stock within a reasonable time after being
notified that the Amex deems such action to be appropriate We have sustained net
losses for our last five fiscal years (and beyond) and our Common Stock has been
trading at relatively low prices. Therefore, our Common Stock may be at risk for
delisting by the Amex.

         Upon any such delisting, the Common Stock would become subject to the
penny stock rules of the SEC, which generally are applicable to equity
securities with a price of less than $5.00 per share (other than securities
registered on certain national securities


                                       14



exchanges or quoted on the Nasdaq system, provided that current price and volume
information with respect to transactions in such securities is provided by the
exchange or system). The penny stock rules require a broker-dealer, prior to a
transaction in a penny stock not otherwise exempt from the rules, to deliver a
standardized risk disclosure document prepared by the SEC that provides
information about penny stocks and the nature and level of risks in the penny
stock market. The broker-dealer also must provide the customer with bid and ask
quotations for the penny stock, the compensation of the broker-dealer and its
salesperson in the transaction and monthly account statements showing the market
value of each penny stock held in the customer's account. In addition, the penny
stock rules require that, prior to a transaction in a penny stock that is not
otherwise exempt from such rules, the broker-dealer must make a special written
determination that the penny stock is a suitable investment for the purchaser
and receive the purchaser's written agreement to the transaction. These
disclosure requirements are likely to have a material and adverse effect on
price and the level of trading activity in the secondary market for a stock that
becomes subject to the penny stock rules. If our Common Stock were to become
subject to the penny stock rules it is likely that the price of the Common Stock
would decline and that our stockholders would be likely to find it more
difficult to sell their shares.

OUR STOCK PRICE HAS BEEN, AND COULD BE, VOLATILE.

         Market prices for our Common Stock and the securities of other medical,
high technology companies have been volatile. Our Common Stock has had a high
price of $0.40 and a low price of $2.10 in the 52-week period ending April 30,
2004. Factors such as announcements of technological innovations or new products
by us or by our competitors, government regulatory action, litigation, patent or
proprietary rights developments and market conditions for medical and high
technology stocks in general can have a significant impact on the market for our
Common Stock.

OUR STOCK HISTORICALLY HAS BEEN THINLY TRADED. THEREFORE, STOCKHOLDERS MAY NOT
BE ABLE TO SELL THEIR SHARES FREELY.

         While our Common Stock is listed on the Amex, the volume of trading
historically has been relatively light. Although trading volume has increased
recently, there can be no assurance that this increased trading volume, our
historically light trading volume, or any trading volume whatsoever will be
sustained in the future. Therefore, there can be no assurance that our
stockholders will be able to sell their shares of our Common Stock at the time
or at the price that they desire, or at all.

ANTI-TAKEOVER PROVISIONS IN OUR CHARTER DOCUMENTS AND DELAWARE LAW COULD PREVENT
OR DELAY A CHANGE IN CONTROL.

         Our Certificate of Incorporation and Bylaws may discourage, delay or
prevent a merger or acquisition that a stockholder may consider favorable by
authorizing the issuance of "blank check" preferred stock. The Board of
Directors may issue this preferred stock, on such terms as it determines,
without further stockholder approval. Therefore, the Board may issue such
preferred stock on terms unfavorable to a potential bidder in the event that is
opposes a merger or acquisition. In addition, our classified Board of Directors
may discourage such transactions by increasing the amount of time necessary to
obtain majority representation on the Board. We also have implemented a
stockholder rights plan and distributed rights to our stockholders. When these
rights become exercisable, these rights entitle their holders to purchase one
share of our Series C Junior Participating Preferred Stock at a price o f $4.46
per one ten-thousandth of a share of Series C Preferred Stock. If any person or
group acquires more than 15% of our Common Stock, the holders of rights (other
than the person or group crossing the 15% threshold) will be able to purchase,
in exchange for the $4.46 exercise price, $8.92 of our Common Stock or the stock
of any company into which we are merged. Because these rights may substantially
dilute stock ownership by a person or group seeking to take us over without the
approval of our Board of Directors, our rights plan could make it more difficult
for a person or group to take us over (or acquire significant ownership interest
in us) without negotiating with our Board regarding such a transaction. Certain
other provisions of our Bylaws and of Delaware law may also discourage, delay or
prevent a third party from acquiring or merging with us, even if such action
were beneficial to some, or even a majority, of our stockholders.

                                 USE OF PROCEEDS

         The Selling Stockholders will receive all of the net proceeds from the
sale of their respective Shares; we will not receive any proceeds from these
sales. The holders of the Warrants are under no obligation to exercise them at
any time or at all.

         The exercise price for the Warrants is payable in cash (except that
Warrants to purchase 121,680 shares at $0.77 per share are subject to "cashless"
or "net" exercise provisions). If all of the Warrants (including those subject
to "cashless" exercise) are


                                       15



exercised for cash, we will receive aggregate consideration of $4,504,032. We
intend to use any proceeds from exercise of the Warrants for working capital and
general corporate purposes.

                         RESALES BY SELLING STOCKHOLDERS


         This Prospectus relates to the proposed resale by the Selling
Stockholders of the Shares, consisting of up to 8,652,441 shares of Common
Stock, and up to 4,723,698 shares of Common Stock issuable upon the exercise of
the Warrants. The following table sets forth, as of May 21, 2004, certain
information with respect to the persons for whom the Company is registering the
Shares for resale to the public. Except as indicated by footnote below, no such
person has had a material relationship or has held any position or office, with
the Company within the last three years and, to our knowledge, based on
information provided by the Selling Stockholders, no such person is a
broker-dealer or an affiliate of a broker-dealer. The Company will not receive
any of the proceeds from the sale of the Shares, but may receive up to
$4,604,032 upon the cash exercise of the Warrants.

----------

(1)      We have computed "beneficial ownership" in accordance 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 May 21, 2004.
         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, however, included the Shares
         underlying warrants and registered hereby under the column "Securities
         Beneficially Owned Prior to Offering--Common Stock." Instead, the
         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 of Common Stock 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 the Shares owned thereby or issuable thereto.

(4)      Until February 2004, Mr. Mon was a director of the Company and, until
         May 2004, he served as corporate secretary. Mr. Mon has been, and
         continues to be, a vice president of the Company.

(5)      Dr. Cheung is a director and serves as president, chief executive
         officer and chief scientific officer of the Company.

                              PLAN OF DISTRIBUTION

         The Selling Stockholders may, in their discretion, offer and sell
Shares from time to time on The American Stock Exchange or otherwise at prices
and on terms then prevailing at prices related to the then-current market price,
or at negotiated prices. The distribution of the Shares may be effected from
time to time in one or more transactions including, without limitation:

         o   ordinary brokerage transactions and transactions in which the
             broker solicits purchasers;

         o   transactions involving block trades;

         o   purchases by a broker, dealer or underwriter as principal and
             resale by that person for its own account under this Prospectus;

         o   put or call option transactions;

         o   privately negotiated transactions; or

         o   by any other legally available means.

         In effecting sales, broker-dealers or agents engaged by the Selling
Stockholders may arrange for other broker-dealers or agents to participate. From
time to time, one or more of the Selling Stockholders may pledge, hypothecate or
grant a security interest in some or all of the Shares owned thereby, and the
pledgees, secured parties or persons to whom such securities have been
hypothecated shall, upon foreclosure in the event of default, be deemed to be
Selling Stockholders under this Prospectus. In addition, the Selling
Stockholders may from time to time sell short the Common Stock of the Company
and, in such instances, this Prospectus may be delivered in connection with such
short sale and the Shares offered hereby may be used to cover such short sale.

         Sales of Selling Stockholders' Shares may also be made pursuant to Rule
144 under the Securities Act of 1933, where applicable. The Selling
Stockholders' Shares may also be offered in one or more underwritten offerings,
on a firm commitment or best efforts basis. The Company will receive no proceeds
from the sale of Shares by the Selling Stockholders, although it will receive
the exercise price upon any exercise of Warrants.

         To the extent required under the Securities Act of 1933, the aggregate
amount of Selling Stockholders' Common Stock being offered and the terms of the
offering, the names of any such agents, brokers, dealers or underwriters and any
applicable commission with respect to a particular offer will be set forth in an
accompanying Prospectus supplement. Any underwriters, dealers, brokers or agents
participating in the distribution of the Shares may receive compensation in the
form of underwriting discounts, concessions, commissions or fees from a Selling
Stockholder and/or purchasers of Selling Stockholders' Shares, for whom they may
act. In addition, Selling Stockholders may be deemed to be underwriters under
the Securities Act and any profits on the sale of Shares by them may be deemed
to be discounts or commissions under the Securities Act. Selling Stockholders
may have other business relationships with the Company or its affiliates in the
ordinary course of business.

         From time to time, each of the Selling Stockholders may transfer,
pledge, donate or assign their Shares to lenders, family members and others and
each of such persons will be deemed to be a Selling Stockholder for purposes of
this Prospectus. The number of Shares beneficially owned by those Selling
Stockholders who transfer, pledge, donate or assign Shares will decrease as and
when they take such actions. The plan of distribution for the Shares sold
hereunder will otherwise remain unchanged, except that the transferees,
pledgees, donees or other successors will be Selling Stockholders hereunder.


                                       17



          Without limiting the foregoing, in connection with distributions of
the Shares, a Selling Stockholder may enter into hedging transactions with
broker-dealers and the broker-dealers may engage in short sales of the Common
Stock in the course of hedging the positions they assume with such Selling
Stockholder. A Selling Stockholder may also enter into option or other
transactions with broker-dealers that involve the delivery of Shares to the
broker-dealers, who may then resell or otherwise transfer such Shares. A Selling
Stockholder may also lend or pledge Shares to a broker-dealer and the
broker-dealer may sell the Shares so borrowed or, upon default, may sell or
otherwise transfer the pledged Shares.

         Under applicable rules and regulations under the Securities Exchange
Act, any person engaged in the distribution of the Common Stock may not bid for
or purchase shares of Common Stock during a period which commences one business
day (five business days, if the Company's public float is less than $25 million
or its average daily trading volume is less than $100,000) prior to such
person's participation in the distribution, subject to exceptions for certain
passive market making activities. In addition and without limiting the
foregoing, each Selling Stockholder will be subject to applicable provisions of
the Securities Exchange Act and the rules and regulations thereunder, including,
without limitation, Regulation M, which provisions may limit the timing of
purchases and sales of shares of the Company's Common Stock by such Selling
Stockholder.

         The Company is bearing all costs relating to the registration of the
Shares (other than fees and expenses, if any, of counsel or other advisors to
the Selling Stockholders). Any commissions, discounts or other fees payable to
broker-dealers in connection with any sale of the Shares will be borne by the
Selling Stockholders selling such Shares.

         The Company may indemnify the Selling Stockholders in certain
circumstances, against certain liabilities, including liabilities arising under
the Securities Act of 1933.

                                  LEGAL MATTERS
