The terms the "Company," "Celsion," "we," "us" and "our" used in this Summary and throughout this Prospectus all refer to Celsion Corporation. GENERAL We develop medical treatment systems primarily to treat breast cancer and a chronic prostate enlargement condition, common in older males, known as benign prostatic hyperplasia, or BPH, using minimally invasive focused heat technology. We also are working with Duke University on the development of heat-sensitive liposome compounds for use in the delivery of chemotherapy drugs to tumor sites, and with the Memorial Sloan-Kettering Cancer Center, or Sloan-Kettering, on the development of heat-activated gene therapy compounds. 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 more than 9 million men in the United States experience BPH symptoms and that more than 26 million men are affected by BPH worldwide. As the population continues to age, the prevalence of BPH can be expected to continue to increase. It is generally estimated that approximately 50 percent of all men over the age of 55 and 90 percent 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) 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, 1

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 currently 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 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 percent 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 presently available appear to provide fully satisfactory, cost-effective treatment solutions for BPH sufferers. Celsion BPH Treatment System We have developed a BPH treatment system - "Microwave Uretheroplasty(TM)" - 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. Treatment using this system consists of two fundamental elements: - Celsion's proprietary catheter, incorporating a balloon enlargement device, delivers computer-controlled transurethral microwave heating directly to the prostate at temperatures greater than 44(0) C (111(0) F). - 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 effectively kills 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 BPH system's relatively low temperature (43(0) C to 45(0) C) (109(0) F to 113 (0) F) 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 investigational, minimally invasive Microwave Uretheroplasty(TM) 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 Microwave Uretheroplasty(TM) 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. Ultimate Food and Drug Administration, or FDA, approval for a device such as our equipment typically requires two phases of clinical testing. The purpose of Phase I testing is to show feasibility and safety and involves a small group of patients. Phase II testing is designed to show safety and efficacy. The FDA approved an Investigational Device Exemption, or IDE, to allow clinical testing of our BPH system in June 1998 and we completed initial Phase I clinical feasibility human trials of the BPH system at Montefiore Medical Center in May 1999. In the Phase I trials, the combination of computer-controlled microwave heat and balloon catheter expansion was able to increase peak flow rates and to provide immediate relief of symptoms caused by BPH. In addition, we undertook an expanded Phase I study to test an accelerated treatment protocol, which was completed in May 2000, at Montefiore Medical Center. In July 2000, the FDA approved the commencement of multiple-site Phase II studies to collect the safety and efficacy data necessary for FDA premarketing approval (PMA) for commercialization. All 160 patients required to be treated under the Phase II trial were treated as of November 29, 2001 and, as of that date, we submitted the first two of three required modules to the FDA in support of the PMA. We expect to submit the last module, consisting of clinical data, in December 2002 or early 2003. If Phase II testing produces anticipated results and if our BPH 2

system meets all other requirements for FDA approval and receives such approval, we intend to begin marketing the BPH system during the second calendar quarter of 2003. Based on the information we have collected to date, we believe that our BPH system has the potential to deliver a treatment that is performed in one hour or less on an outpatient basis, generally would not require post-treatment catheterization, and would deliver symptomatic relief and an increase in urinary flow rates promptly after the procedure is completed. BREAST CANCER TREATMENT SYSTEM 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 generally 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 the 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, or MIT, who had developed, originally for the United States Defense Department, the microwave control technology known as "Adaptive Phased Array", or 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 Microfocus equipment capable of focusing microwave energy on specific tissue areas. We have now 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. 3

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(0) C (115(0) 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 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 (IIA) is designed to ablate (kill) small breast tumors using heat alone and the second (IIB) 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 Columbia Hospital, in Florida, Harbor UCLA in California and Halle Martin Luther Breast Center in Halle, Germany. We expect to add additional sites, both within the United States and in Europe, during the remainder of calendar 2002. In July 2002, we reached the endpoint for the IIB protocol by determining the maximum heat dosage required to optimize the treatment. Results to date have been encouraging. Post-operative pathology showed that in 24 out of the 25 patients treated with the Celsion's system the margins of the excised tumor were clear of all the viable cancer cells and no further surgery was required. We also have learned from our current and potential clinical investigators that our breast cancer treatment system has the potential to meet a significant unmet need in the realm of breast cancer treatment. Currently 25 to 30 percent of all lumpectomy patients are recalled for a second surgery (commonly referred to as a second incision) when, through pathological examinations, the surgeon discovers that viable cancer cells remain in the margins surrounding the area from which the tumor has been removed. This additional procedure is costly for the surgeon and other medical providers and traumatic for the patient. We believe that studies will demonstrate that our treatment system, in conjunction with lumpectomy, would lead to a reduction in the rate of second incisions. Based on our Phase II trial results to date and our new learning, we decided to revise our IIB protocol to provide a clinical endpoint demonstrating that the incidence of second incision could be significantly reduced if a patient underwent treatment with our system prior to lumpectomy. We submitted the revision of our IIB protocol to the FDA in July 2002 and, in August 2002, the FDA approved our revised protocol on condition that the IIB trials be expanded from 43 to 222 patients, with half the patients being treated with Celsion's system followed by lumpectomy and the remainder undergoing conventional lumpectomies alone. At the same time, we reviewed and revised our IIA protocol to clarify the clinical endpoints. As revised, the IIA trials will now be fully randomized against patients receiving preoperative chemotherapy alone and the study size has been increased from 130 to 312 patients. Treatments under both protocols were halted while the revisions were in process. We anticipate that both the IIA and IIB trials will be completed by the end of calendar year 2003 and, if successful, that we will file for the addition of new indications of use to the existing FDA premarketing approval for our Microfocus 1000 equipment. THERMO-LIPOSOMES--DUKE UNIVERSITY TECHNOLOGY 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 a tumor, severely limiting the clinical efficacy of liposome chemotherapy treatments. 4

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 which have been heated for 30 to 60 minutes than in areas that do not receive heat. In animal trials it has been determined that heat-sensitive liposomes deposited 50 times the amount of drugs 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 5mg per kilogram Doxorubicin concentration. This was immediately followed by heating of the tumor to 42(0) C (108(0) 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 the 60 days of the study. In November 2001, we completed large animal toxicity studies involving our Doxorubicin-laden thermo-liposome at the Roswell Park Cancer Institute, a cancer research organization in Buffalo, New York. In March 2002, we filed an Investigational New Drug (IND) application with the FDA for the use of this liposome in the treatment of prostate cancer using our Microfocus equipment as the means of heat activation. In June 2002, the IND became effective allowing us to proceed with human clinical trials. We expect to start the Phase I clinical trials at Roswell Park Cancer Institute in November 2002. In addition, in January 2001, we entered into a Material Transfer Agreement, or MTA, with the National Cancer Institute, or NCI, under which we will supply heat-activated liposomes to enable the NCI to conduct clinical trials on liver cancer. NCI will use 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 expects to complete the animal toxicity studies in the fall of 2002 and to submit an IND application to the FDA for approval early in 2003. 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. Production of Heat-Sensitive Liposomes We have established a relationship with British Columbia Cancer Authority, or BCCA, of Vancouver, Canada to provide Quality System Regulation, or QSR (formerly Good Manufacturing Practices, or GMP), production of our heat-activated liposome for our now completed large animal toxicity studies under our Material Transfer Agreement with the National Cancer Institute and for our planned Phase I clinical study in humans. BCCA is a leading drug formulation and discovery company that specializes in liposome drug development. Celsion will require a large-scale liposome manufacturer at such time, if any, as it reaches Phase II clinical trials and beyond. Toward that end, we are in the process of identifying a large-scale producer of the Doxorubicin-based heat-activated liposome. 5

HEAT-ACTIVATED GENE THERAPY COMPOUNDS -- SLOAN-KETTERING TECHNOLOGY 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 Memorial Sloan-Kettering Cancer Center a biomedical innovation that we believe has significant potential to improve cancer therapy. Sloan-Kettering has developed a biological modifier that inhibits 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 seeking methods to mitigate these side effects. In radiation therapy, such methods 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(0) C (106(0) F). This focused heat may be generated by Celsion's Adaptive Phased Array microwave technology, which provides deep heating without damage to surrounding healthy tissue. 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 being conducted and are expected to continue into 2003. Based on the current development timeline, we expect to file an IND application with the Food and Drug Administration by the end of calendar year 2003 and anticipate that we will be in a position to commence Phase I clinical (human) trials before the end of calendar year 2004. At such time as we determine safety and dosage in our preliminary studies, we expect to form partnership(s) with one or more drug companies to scale-up manufacturing and marketing for larger pivotal studies. In May 2000, we entered into an exclusive worldwide agreement for the commercial rights to the heat-activated gene therapy technology developed by Sloan-Kettering. 6

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. 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 $(33,605,157) at September 30, 2001, including losses of $(4,547,215) for the fiscal year ended September 30, 2000 and $(6,923,227) for the fiscal year ended September 30, 2001. As of June 30, 2002, the accumulated deficit was $41,703,593, including net loss of for the first nine months of the current fiscal year of $(8,017,528). Because we presently have no 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. 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 have scheduled a special meeting of our shareholders for November 8, 2002 to approve an increase in the number of authorized shares of our Common Stock from 150,000,000 to 200,000,000 shares. If the shareholders do not approve this increase, our ability to raise additional capital through the sale of Common Stock will be severely limited. WE DO NOT EXPECT TO GENERATE SIGNIFICANT REVENUE FOR THE FORESEEABLE FUTURE. We marketed and sold our original microwave thermotherapy products, which produced modest revenues from 1990 to 1994, but ceased marketing these products in 1995. We have devoted our resources in ensuing years to developing a new generation of thermotherapy and other products, but cannot market these products unless and until we have completed clinical testing and obtained all necessary governmental approvals. Accordingly, we have no current source of revenues, much less profits, to sustain our present operations, and no revenues will be available unless and until our 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. OUR MICROWAVE HEAT THERAPY TECHNOLOGY IS STILL UNDERGOING CLINICAL TESTING AND 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 that study, the Health Care Financing Administration, a 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 completed and submitted to the FDA only Phase I clinical trials of our Microwave Uretheroplasty(TM) treatment system, although we have completed patient treatments in our Phase II trials. Our PMA application is being submitted on a modular basis, consisting of three separate filings: a manufacturing module, a pre-clinical module and a module consisting of 12-month patient follow-up data. The first two out of three modules were submitted in November 2001 and the remaining module will be submitted after the 12-month patient follow-up data has been collected and the first two modules have been cleared by the FDA. The manufacturing module has been cleared already and we anticipate that the FDA will clear the pre-clinical module in the near future. Therefore, we presently anticipate that we will submit the third module before the end of calendar year 2002. Our new breast cancer treatment technology is currently in Phase II trials. Our technology may not prove as effective in practice as we anticipate based on testing to date. If further testing and clinical practice do not confirm the safety and efficacy of our technology or, 7

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 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 favorable 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 BPH and breast cancer treatment systems and heat-activated liposome and cancer repair inhibitor products, as well as other potential new products. We expended approximately $6,800,000 in the fiscal year ending September 30, 2001. As of that date, we had available a total of approximately $2,500,000 to fund additional expenditures. On January 9, 2002, we completed a private placement of units consisting of one share of Common Stock, par value $0.01 per share and a warrant to purchase one share of Celsion Common Stock, at a price of $0.50 per unit, resulting in gross proceeds to the Company of $6,250,000. On June 3, 2002, the Company completed a private placement of 2,000 units at a price per unit of $1,000, resulting in gross proceeds to the Company of $2,000,000. Each unit in this offering consists of one share of the Company's 8% Series B Convertible Preferred Stock and a warrant to purchase 600 shares of Common Stock. On October 15, 2002, the Company completed a private placement of 15.5 units at a price per unit of $50,000, resulting in gross proceeds to the Company of $775,000 Each unit in this offering consists of 150,000 shares of the Company's Common Stock. It is our current intention both to increase the pace of development work on our present products and to make a significant commitment to our heat-activated liposome and cancer repair inhibitor research and development projects. 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 begin marketing our products and to generate sufficient cash flow from sale of those 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. Also, 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. 8

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. 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 European Union, or 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 EU certifications for any new facilities or for our products, or that we will be able to maintain our 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 our activities or provide an advantage to larger companies that compete with us. 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 we develop. 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 nine utility patents pending in the United States Patent & Trademark Office. One application directed to our breast cancer treatment and another application directed to our Microwave Uretheroplasty(TM) treatment for BPH have been allowed and should issue as United States patents within the next few months. We have filed international applications with respect to the above technologies in various countries including Japan, China, Europe, and Canada. Three additional U.S. utility applications are on file directed to various features of our breast cancer treatment and three additional applications are on file directed to different features of our thermotherapy treatment of BPH. The ninth application on file is directed to our deep tumor therapy treatment. However, even when our pending applications mature into United States patents, our business will still depend on license agreements that we have entered into with third parties until the third parties' patents expire. We intend to file applications for international patent protections for inventions covered by our U.S. applications. However, there can be no assurance when, if ever, we will receive such international patent protection. 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 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 9

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. Also, loss of our rights under the MIT license agreement would prevent us from proceeding with our most 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 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 we 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, 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 OUR BUSINESS STRATEGY AND DEVELOP OUR 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. Effective October 4, 2001, Spencer J. Volk, formerly the President, Chief Executive Officer and a director of Celsion, resigned from all of these positions. Our Board has appointed Dr. Augustine Y. Cheung, formerly the Chairman and Chief Scientific Officer, to serve as Celsion's President and Chief Executive Officer and Dr. Max Link, a director since 1997, has assumed the position of Chairman of the Board. Effective September 20, 2002, Dr. LaSalle Leffall resigned as a member of our Board of Directors. There currently are two vacancies on the Board of Directors which we are attempting to fill with qualified candidates. However, we cannot be sure when we will be able to fill these vacancies. 10

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 we add to our manufacturing, marketing, sales, research and development and other capabilities, 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 business 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. 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, universities and other research institutions. Substantially all of our competitors and potential competitors have significantly 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. 11

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 intend to market our Microwave Uretheroplasty(TM) treatment system either directly or through strategic alliances, distribution arrangements or other arrangements with third parties at such time, if any, as it is approved for commercialization by the FDA, and to market our breast cancer treatment system, if and when so approved, through such third parties. There can be no assurance that we will be able to establish sales and marketing capabilities successfully or successfully enter into third-party marketing or distribution arrangements. We have limited experience and capabilities in marketing, distribution and direct sales, although we intend to develop an effective sales and marketing capability as we pursue commercialization. We expect to incur significant additional expense in attracting, establishing and maintaining a marketing and sales force or entering into third-party marketing or distribution arrangements. There can be no assurance that, to the extent we enter into any commercialization arrangements with third parties, 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. 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 Microwave Uretheroplasty(TM) equipment 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 might result in delays and additional expense in being able to make prototype equipment available for clinical trials and other research purposes. In addition, inasmuch as we expect to manufacture our Microwave Uretheroscopy equipment at least for some period subsequent to FDA approval and the commencement of commercialization, such manufacturing and commercialization also could be delayed. In addition, in the event that we succeed in marketing our products, we intend to use outside contractors to supply components and the Microwave Uretheroplasty(TM) catheter, and may use such contractors to assemble finished equipment in the future, which could cause us to become increasingly dependent on key vendors. 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 Stock 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 OR CONVERSION OF OUR OUTSTANDING OPTIONS, WARRANTS AND CONVERTIBLE PREFERRED STOCK COULD RESULT IN SIGNIFICANT DILUTION OF OWNERSHIP INTERESTS IN OUR COMMON STOCK OR OTHER CONVERTIBLE SECURITIES. Options and Warrants. As of September 30, 2002, we had outstanding and exercisable warrants and options to purchase a total of 30,376,600 shares of our Common Stock at exercise prices ranging from $0.01 to $5.00 per share (and a weighted average exercise price of approximately $0.60 per share). In addition, we had outstanding but unexercisable and unvested warrants and options to purchase a total of 4,394,998 shares of our Common Stock at exercise prices ranging from $0.50 to $ 1.36 per share. Some of the exercise prices are below the current market price of our Common Stock, which ranged from a low of $0.36 to a high of $0.46 over the 20 trading days ending September 30, 2002. 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 12

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 of 1933, will be able to sell in the public market some or all of shares of Common Stock purchased upon such exercise. Preferred Stock. As of September 30, 2002 we had outstanding a total of 893 shares of Series A 10% Convertible Preferred Stock (plus 238 shares representing accrued dividends). The shares of Series A Preferred Stock are subject to exchange and conversion privileges upon the occurrence of major events, including a public offering of our securities or our merger with a public company. In addition, the holders of the Series A Preferred Stock are entitled to convert their preferred shares into shares of Common Stock at a conversion price of $0.41 per share of Common Stock, subject to certain adjustments. The holders of the Series A Preferred Stock also have registration rights at such time, if any, as we undertake a registered public offering of securities. Even without such registration, holders of the Series A Preferred Stock who satisfy the requirements of Rule 144 of the Securities Act of 1933 will be able to sell in the public market shares of Common Stock acquired upon the conversion of Series A Preferred Stock. There also were outstanding warrants to purchase 36 shares of Series A Preferred Stock (convertible into an additional 87,805 shares of Common Stock) as of September 30, 2002. As of September 30, 2002, we had outstanding a total of 1,550 shares of Series B 8% Convertible Preferred Stock (plus 41shares representing accrued dividends). The holders of the Series B Preferred Stock are entitled to convert their preferred shares into shares of Common Stock at a conversion price of $0.50 per share of Common Stock, subject to certain adjustments. The holders of the Series B Preferred Stock became entitled to registration of the shares of Common Stock underlying their shares of Series B Preferred Stock as of September 3, 2002, the date on which the shares of Series B Preferred Stock first became convertible. Even without such registration, holders of the Series B Preferred Stock who satisfy the requirements of Rule 144 of the Securities Act of 1933 will be able to sell in the public market shares of Common Stock acquired upon the conversion of Series B Preferred Stock. The conversion of the Series A and Series B Preferred Stock could have a dilutive effect on our stockholders and could adversely affect the market price of our issued and outstanding Common Stock and convertible securities. 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 could 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 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 find it more difficult to sell their shares. 13

OUR STOCK PRICE COULD BE VOLATILE. Market prices for our Common Stock and the securities of other medical, high technology companies have been volatile. 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. 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. 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. 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. We also have adopted a stockholder rights plan and declared a dividend distribution of one right for each outstanding share of Common Stock to stockholders of record as of August 6, 2002. When it becomes exercisable, each right entitles the registered holder to purchase from Celsion one ten-thousandth of a share of Series C Junior Participating Preferred Stock, par value $0.01 per share, or Series C Preferred Stock, at a price of $4.46 per one ten-thousandth (1/10,000) of a share of Series C Preferred Stock, subject to adjustment. Under certain circumstances, if a person or group acquires 15% or more of our outstanding Common Stock, holders of the rights (other than the person or group triggering their exercise) will be able to purchase, in exchange for the $4.46 exercise price, shares of our Common Stock or of any company into which we are merged having a value of $8.92. The rights expire on August 15, 2012, unless earlier redeemed by our Board of Directors. Because the rights may substantially dilute the stock ownership of a person or group attempting to take us over without the approval of our Board of Directors, our rights plan also could make it more difficult for a third party to acquire us (or a significant percentage of our outstanding capital stock) without first negotiating with our Board of Directors regarding such acquisition. 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. We will, however, receive proceeds from any exercises of the Warrants at the rate of up to $0.65 per share. 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. If all of the Warrants were exercised for cash, we would receive maximum aggregate consideration of $2,196,000. We intend to use any proceeds from exercise of the Warrants for completion of the breast cancer clinical trials, 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 3,243,000 currently outstanding Shares, 3,193,000 Shares underlying shares of the Company's Series B 8% Convertible Preferred Stock (including accrued dividends), and up to 3,600,000 Shares issuable upon the exercise of certain Common Stock purchase warrants (the "Warrants"), 1,800,000 of which shares underlying the Warrants are issued and outstanding and the remaining 1,800,000 of which shares are subject to issuance, in whole or in part, if the Company's Common Stock does not meet certain price criteria. The following table sets forth, as of October 15, 2002, 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. The Company will not receive any of the proceeds from the sale of the Shares, but may receive up to $2,196,000 upon the cash exercise of the Warrants. 14

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 September 30, 2002. 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. 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. 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). 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) Including 2,060,000 shares issuable up conversion of the Company's Series B 8% Convertible Preferred Stock. (5) Including 618,000 shares issuable up conversion of the Company's Series B 8% Convertible Preferred Stock. (6) Including 206,000 shares issuable up conversion of the Company's Series B 8% Convertible Preferred Stock (7) Including 309,000 shares issuable up conversion of the Company's Series B 8% Convertible Preferred Stock (8) Including 154,472 shares issuable up conversion of the Company's Series A 8% Convertible Preferred Stock * Less than 1%. 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. 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 of 1934, 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 of 1934 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. 15

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 The legality of the securities in this offering has been passed upon for us by our counsel, Venable, Baetjer, Howard & Civiletti, LLP of Washington, DC. EXPERTS Our financial statements at September 30, 1999, 2000 and 2001 for the fiscal years ended September 30, 1999, 2000 and 2001 are incorporated by referenced into this Prospectus from our Annual Report on Form 10-K for the fiscal year ended September 30, 2001 have been audited by Stegman & Co., independent accountants, and are so incorporated by reference in reliance upon such report given upon the authority of such firm as experts in accounting and auditing.

II-4 PART II INFORMATION NOT REQUIRED IN PROSPECTUS Item 14. Other Expenses of Issuance and Distribution. We estimate that our expenses to be paid in connection with the offering (other than placement agent discounts, commissions and reasonable expense allowances), all of which will be paid by the Company, will be as follows: SEC Registration Fee.................... $361 American Stock Exchange Listing Fee..... $22,500 Accounting Fees and Expenses............ $500 Legal Fees and Expenses................. $25,000 Printing and Engraving.................. $200 Miscellaneous........................... $5,000 ------ Total $53,561 - ----- *These are estimated amounts. Item 15. Indemnification of Directors and Officers. The Company is organized under the laws of the State of Delaware. Our Certificate of Incorporation provides that we shall indemnify our current and former directors and officers, and may indemnify our current and former employees and agents, against any and all liabilities and expenses incurred in connection with their services in those capacities to the maximum extent permitted by Delaware law. The Delaware General Corporation Law (the "DGCL") provides that a Delaware corporation has the power generally to indemnify its current and former directors, officers, employees and other agents (each, a "Corporate Agent") against expenses and liabilities (including amounts paid in settlement) in connection with any proceeding involving such person by reason of his being a Corporate Agent, other than a proceeding by or in the right of the corporation, if such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal proceeding, such person had no reasonable cause to believe his conduct was unlawful. In the case of an action brought by or in the right of the corporation, indemnification of a Corporate Agent is permitted if such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation. However, no indemnification is permitted in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation, unless and only to the extent that the court in which such proceeding was brought shall determine upon application that despite the adjudication of liability, but in view of all the circumstances of the case, such person is fairly and reasonably entitled to such indemnification. To the extent that a Corporate Agent has been successful on the merits or otherwise in the defense of such proceeding, whether or not by or in the right of the corporation, or in the defense of any claim, issue or matter therein, the corporation is required to indemnify such person for expenses in connection therewith. Under the DGCL, the corporation may advance expenses incurred by a Corporate Agent in connection with a proceeding, provided that the Corporate Agent undertakes to repay such amount if it shall ultimately be determined that such person is not entitled to indemnification. Our Certificate of Incorporation requires us to advance expenses to any person entitled to indemnification, provided that such person undertakes to repay the advancement if it is determined in a final judicial decision from which there is no appeal that such person is not entitled to indemnification. The power to indemnify and advance the expenses under the DGCL does not exclude other rights to which a Corporate Agent may be entitled to under the Certificate of Incorporation, Bylaws, agreement, vote of stockholders or disinterested directors or otherwise. Our Certificate of Incorporation permits us to secure insurance on behalf of our directors, officers, employees and agents for any expense, liability or loss incurred in such capacities, regardless of whether the Certificate of Incorporation or Delaware law would permit indemnification against such expense, liability or loss. II-1

The purpose of these provisions is to assist us in retaining qualified individuals to serve as our directors, officers, employees and agents by limiting their exposure to personal liability for serving as such.

(A) The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in the registration statement; II-2

provided, however, that paragraphs A(1)(i) and A(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment to this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (B) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (C) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

                            (A DELAWARE CORPORATION)


                         PURSUANT TO SECTION 151 OF THE
                GENERAL CORPORATION LAW OF THE STATE OF DELAWARE
                                -----------------

         CELSION  CORPORATION,  a corporation  organized and existing  under the
General  Corporation  Law of the State of Delaware (the  "Corporation"),  by its
President,

         DOES HEREBY CERTIFY:

         FIRST:  That,  pursuant to authority  expressly  vested in the Board of
Directors  of  the   Corporation  by  the  provisions  of  its   Certificate  of
Incorporation,  the Board of  Directors  duly adopted the  following  resolution
providing for the designation and issuance of up to Five Thousand (5,000) shares
of Series B 8% Convertible Preferred Stock, $0.01 par value:

                           RESOLVED,  that this Board of Directors,  pursuant to
                  authority  expressly  vested  in it by the  provisions  of the
                  Certificate  of  Incorporation  of  the  Corporation,   hereby
                  authorizes  the  issue  from  time  to  time  of a  series  of
                  Preferred  Stock  of the  Corporation  and  hereby  fixes  the
                  designation,  preferences,  and the  relative,  participating,
                  optional or other rights, and the qualifications,  limitations
                  or restrictions thereof, in addition to those set forth in the
                  Corporation's  Certificate  of  Incorporation,  to be in their
                  entirety as follows:

         1. Designation, Par Value and Number of Shares.

                  The formal  designation  of the  shares  shall be "Series B 8%
Convertible  Preferred  Stock"  (referred to herein for convenience as "Series B
Preferred  Stock"  or as  "Preferred  B  Shares").  The par  value  of  Series B
Preferred  Stock is $0.01 per share.  The Series B Preferred Stock shall consist


                                       1

of Five Thousand (5,000) shares. 2. Liquidation Preference and Ranking. (a) Upon any voluntary or involuntary liquidation, dissolution or winding up of the business and affairs of the Corporation, and before the holders of shares of the Corporation's common stock, par value $0.01 per share (the "Common Stock") or any other class or series of stock of the Corporation ranking junior in liquidation to the Series B Preferred Stock shall be entitled to any payment on account of such shares, the holders of Series B Preferred Stock then outstanding shall be entitled to receive, as a liquidation preference, an amount equal to One Thousand Dollars ($1,000) per share (the "Original Cost"), plus any accrued but unpaid dividends (the Original Cost plus such dividends being referred to as the "Liquidation Preference") to which such stockholders have become entitled and which have not theretofore been paid. After the holders of Series B Preferred Stock shall have received such payment of the Liquidation Preference plus all accrued and unpaid dividends in the course of such liquidation, dissolution or winding up, they shall have no right or claim to any of the remaining assets of the Corporation. (b) If, upon any liquidation, dissolution or winding up, the Corporation shall have insufficient funds to permit payment to the holders of Series B Preferred Stock then outstanding of the entire amount to which they are entitled as a Liquidation Preference, then such funds as are available for such purpose shall be distributed among such holders on the basis of the number of shares of Series B Preferred Stock held by each such holder so that, as nearly as may be practicable, the amount each such holder shall receive shall represent the same proportion of such available funds as such holder's total holding of shares of Series B Preferred Stock represents of the total shares of Series B Preferred Stock outstanding at the time. (c) For all purposes under this Certificate of Designations, all shares of Series B Preferred Stock shall be of equal rank with each other. (d) For all purposes under this Certificate of Designations, shares of Series B Preferred Stock shall rank in parity with shares of the Corporation's Series A 10% Convertible Preferred Stock. 3. Dividends. (a) The holders of Series B Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors of the Corporation, out of capital surplus or earnings at the time legally available therefor, dividends at the annual rate of eight percent (8%) per share, payable in fully-paid and non-assessable shares of Series B Preferred Stock which shall be valued, for this purpose, at an amount equal to the Original Cost (as adjusted in a manner similar to that provided for the Conversion Price in Section 9(a), as applicable). Dividends shall accrue, whether or not declared, unless such dividends are then prohibited by the provisions of the Delaware 2

General Corporation Law or the Corporation's Certificate of Incorporation. (b) Dividends shall be cumulative and shall be payable semi-annually on December 31 and on June 30 commencing with December 31, 2002, to stockholders of record on the immediately preceding December 15th and June 15th, respectively, or such other record date as may be fixed for that purpose by the Board of Directors; provided, however, that if December 15th or June 15th shall not be a business day and the Board of Directors shall not fix another record date, the record date shall be the next succeeding business day. Dividends payable with respect to any shares of Series B Preferred Stock for the initial dividend period and for any period less than a full six-month period shall accrue from the date of issuance of such shares of Series B Preferred Stock on which such dividends are payable, and shall be computed and apportioned on the basis of a 180-day period composed of six 30-day months. Holders of Series B Preferred Stock shall not be entitled to any dividends in excess of the full dividends provided for herein, and no interest or sum of money in lieu of interest shall be payable in respect of any dividend payment which may be in arrears. No dividends shall be payable on any fractional or full shares of Series B Preferred Stock which shall have been declared, paid or distributed as dividends on outstanding Preferred B Shares. 4. No Dividends or Distributions to Junior Securities. Except as may be otherwise provided in this Certificate of Designations, so long as any shares of Series B Preferred Stock are outstanding, no dividends shall be declared or paid or set aside for payment, and no other distribution shall be declared or made, upon any Common Stock of the Corporation or upon any other shares of a class or series of stock which is junior in right and ranking to the Series B Preferred Stock, unless all amounts then due to the holders of Series B Preferred Stock, including the dividends provided for herein, have been paid. 5. Voting Rights. Except as otherwise expressly provided herein or as required by law, the Series B Preferred Stock shall have no voting rights. However, notwithstanding the foregoing, the written consent or affirmative vote of the holders of a majority of the outstanding shares of Series B Preferred Stock is required to approve (i) any proposed amendment to the Certificate of Incorporation of the Corporation that would materially alter or change the powers, preferences, or special rights of the Series B Preferred Stock so as to affect the holders adversely, and (ii) any plan of merger or consolidation that contains provisions which, if contained in a proposed amendment to the Certificate of Incorporation of the Corporation, would have entitled the holders of the Series B Preferred Stock to vote, as a class, on the issue. 6. Elective Conversion. The holders of shares of Series B Preferred Stock shall have the following conversion rights: 3

(a) Subject to the terms and conditions of this Section 6, the holder of any share or shares of Series B Preferred Stock shall have the right, at such holder's option at any time commencing with September 3, 2002, to convert any such shares of Series B Preferred Stock (except that upon any liquidation of the Corporation the right of conversion shall terminate at the close of business on the business day fixed for payment of the amount distributable on the Series B Preferred Stock) into such number of fully paid and nonassessable shares of the Corporation's Common Stock as is obtained by (i) multiplying the number of shares of Series B Preferred Stock so to be converted by One Thousand Dollars ($1,000) and (ii) dividing the result by the conversion price of Fifty Cents ($0.50) per share or, in case an adjustment of such price has taken place pursuant to the further provisions hereof, then by the conversion price as last adjusted and in effect at the date any such share or shares of Series B Preferred Stock are surrendered for conversion; provided, that, in no event shall such conversion price be less than $0.01 per share (such price, or such price as last adjusted, being referred to as the "Conversion Price"). (b) The conversion right provided under paragraph (a) of this Section 6 shall be exercised by a holder of the Preferred B Shares subject to conversion by delivering to the Corporation, during regular business hours, or to such agent as may be designated by the Corporation, the original certificate or certificates for the Preferred B Shares to be converted, duly endorsed or assigned either in blank or to the Corporation, accompanied by written notice in substantially the form attached hereto as Exhibit A, stating that the holder elects to convert such Preferred B Shares (or the number of such Preferred B Shares as to which the conversion right is to be exercise) and stating the name or names (with address and Social Security or Federal Taxpayer Identification Number) in which the certificate or certificates for the shares of Common Stock are to be issued. Conversion shall be deemed to have been effected on the date when the aforesaid delivery is made (the "Conversion Date"). (c) As promptly as practicable after the receipt of the written notice referred to in Section 6(b) and surrender of the certificate or certificates for the share or shares of Series B Preferred Stock to be converted, the Corporation shall issue and deliver to such holder (or upon the written order of such holder) to the place designated by such holder, a certificate or certificates for the number of shares of Common Stock to which such holder is entitled as a consequence of such conversion. To the extent permitted by law, the person in whose name the certificate or certificates for Common Stock are to be issued shall be deemed to have become a stockholder of record on the applicable Conversion Date unless the transfer books of the Corporation are closed on that date, in which event such person shall be deemed to have become a stockholder of record on the next succeeding business day on which the transfer books are open and, at such time, the rights of the holder of such Preferred B Share or Shares shall cease. (d) All shares of Series B Preferred Stock which shall have been surrendered for conversion shall no longer be deemed to be outstanding, and all rights with respect to such shares, including the rights, if any, to receive notices and to vote, shall immediately cease and terminate on the Conversion 4

Date, with respect to Preferred B Shares which have been converted, except only the right of the holders thereof to receive shares of Common Stock in conversion therefor. Any shares of Series B Preferred Stock so converted shall be retired and canceled and shall not be reissued, and the Corporation (without the need for stockholder action) may from time to time take such appropriate action as may be necessary to reduce the authorized number of shares of Series B Preferred Stock accordingly. 7. Mandatory Redemption. The Corporation shall have the follow- ing rights to redeem shares of Series B Preferred Stock: (a) Subject to the terms and conditions of this Section 7, the Corporation shall have the right (the "Redemption Right"), at its option at any time (except that, upon any liquidation of the Corporation, the Redemption Right shall terminate at the close of business on the business day fixed for payment of the amount distributable on the Series B Preferred Stock), to redeem and require the conversion of all or a portion of the Preferred B Shares then outstanding for and into such number of fully paid and nonassessable shares of Common Stock (the "Redemption Stock") as is obtained by (i) multiplying the number of shares of Series B Preferred Stock so to be converted and redeemed by One Thousand Dollars ($1,000) and (ii) dividing the result by the Conversion Price. In the event that the Corporation elects to exercise its Redemption Right as to fewer than all of the Preferred B Shares then outstanding, Preferred B Shares shall be redeemed ratably (based on the number of shares held thereby and the total number of Preferred B Shares then outstanding) from each holder thereof. (b) At least twenty (20) calendar days prior to the date selected by the Board of Directors as the effective date for the exercise of its Redemption Right pursuant to this Section 7 (a "Redemption Date") the Corporation shall give notice (a "Redemption Notice") to each holder of record (at the close of business on the business day next preceding the day on which the Redemption Notice is given) of shares of Series B Preferred Stock notifying such holder of the redemption and specifying the Redemption Date, the number of shares of Series B Preferred Stock to be redeemed from such holder, the number of shares of Redemption Stock issuable thereto in respect thereof and the place where said Redemption Price shall be payable. The Redemption Notice shall be addressed to each holder at such holder's address as shown by the records of the Corporation. (c) For a period of ten (10) calendar days following the delivery of the Redemption Notice, each holder of Series B Preferred Stock shall have the right to designate, by means of a notice substantially in the form of Exhibit B hereto, the name or names (with address and Social Security or Federal Taxpayer Identification Number) in which the certificate or certificates for the shares of Redemption Stock are to be issued. In the event that any holder shall, for any reason, fail to make such designation as to some or all of the shares of Redemption Stock issuable thereto, all shares of Redemption Stock not subject to 5

valid and timely designation shall be issued in the name of the holder of the Series B Preferred Stock subject to the Redemption Right. (d) From and after the close of business on a Redemption Date, unless there shall have been a default in issuance of the Redemption Stock as required hereby, all rights of holders of shares of Series B Preferred Stock (except the right to receive the Redemption Stock) shall cease with respect to the shares to be redeemed on such Redemption Date, and such shares shall be retired and canceled and shall not be reissued, and the Corporation (without the need for stockholder action) may from time to time take such appropriate action as may be necessary to reduce the authorized number of shares of Series B Preferred Stock accordingly. 8. Provisions Applicable to Conversions and Redemptions. (a) No fractional shares of Common Stock shall be issued upon conversion or redemption of shares of Series B Preferred Stock into or for shares of Common Stock or Redemption Stock, and the number of shares of Common Stock or Redemption Stock to be delivered upon such conversion or redemption, in lieu of delivering any fractional share, shall be rounded to the nearest whole share (with .5 shares rounded up or down to the even number of shares). Upon conversion of only a portion of the number of shares covered by a certificate representing shares of Series B Preferred Stock surrendered for conversion or upon the written order of the holder of the certificate surrendered for conversion, the Corporation shall issue and deliver to such holder, at the expense of the Corporation, a new certificate covering the number of shares of Series B Preferred Stock representing the unconverted portion of the certificate so surrendered. Upon redemption of only a portion of the number of shares covered by a certificate representing shares of Series B Preferred Stock, the certificate or certificates representing the Preferred B Shares so redeemed shall, from and after the Redemption Date, be deemed for all purposes to represent that number of shares of Series B Preferred Stock not subject to redemption and such certificate or certificates shall be deemed canceled, and of no further effect with respect to shares redeemed; provided, however, that the Corporation shall, upon surrender to it or to such agent as may be designated by the Corporation of the original certificate or certificates for the Preferred B Shares to be redeemed or upon the written order of the holder of the certificate so surrendered, issue and deliver to the holder of any shares of Series B Preferred Stock, at the expense of the Corporation, a new certificate covering the number of shares of Series B Preferred Stock representing the unredeemed portion of the certificate so surrendered. (b) The Corporation shall, at all times when Series B Preferred Stock shall be outstanding, reserve and keep available out of its authorized but unissued Common Stock, for the purpose of effecting the conversion or redemption of Series B Preferred Stock, such number of its duly authorized shares as shall from time to time be sufficient to effect the conversion or redemption of all outstanding shares of Series B Preferred Stock. 6

(c) All shares of Common Stock (including Redemption Stock) which may be issued in connection with the conversion or redemption provisions set forth herein will, upon issuance by the Corporation, be validly issued, fully paid and non-assessable. No adjustment shall be made for dividends on any share of Series B Preferred Stock which is being converted or redeemed (unless such dividends have been accrued and are unpaid as of the Conversion or Redemption Date) or on any share of Common Stock (including Redemption Stock) issued on exercise of a holder's conversion right or the Corporation's Redemption Right as provided herein. (d) The Corporation shall pay any and all issue and other taxes that may be payable in respect of any issuance or delivery of shares of Common Stock (including Redemption Stock) upon conversion or redemption of shares of Series B Preferred Stock pursuant hereto. The Corporation shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of shares of Common Stock (including Redemption Stock) in a name other than that in which the shares of Series B Preferred Stock so converted or redeemed were registered, and no such issuance or delivery shall be made unless and until the person or entity requesting such issuance has paid to the Corporation the amount of any such tax or has established, to the satisfaction of the Corporation, that such tax has been paid. 9. Adjustments to Conversion Price. (a) The Conversion Price (which is initially established at Fifty Cents ($0.50) per share of Common Stock (including Redemption Stock)) in effect from time to time shall be subject to adjustment (to the nearest cent) from time to time as follows: (i) If the Corporation, at any time after June 1, 2002 and at any time prior to the conversion of a Preferred Share shall have subdivided its outstanding shares of Common Stock by recapitalization, reclassi fication or split-up thereof, or if the Corporation shall have declared a stock dividend or distributed shares of Common Stock to its stockholders, the Conversion Price immediately prior to such conversion shall be proportionately increased; and, if the Corporation, prior to such conversion, shall have at any time combined the outstanding shares of Common Stock by recapitalization, re classification or comparable combination thereof, the Conversion Price immediately prior to such conversion shall be proportionately increased. (ii) In case the Corporation, after June 1, 2002, shall consolidate with or merge into another corporation or convey all or substantially all of its assets to another corporation, then, and in each such case, the Conversion Price shall be adjusted in such manner that the holder of Preferred B Shares, upon the conversion or redemption thereof as provided herein, at any time after the consummation of such consolidation, merger or conveyance, shall be entitled to receive the securities or property to which such holder would have been entitled upon such consummation if such holder had exercised his right to convert such Preferred B Shares immediately prior thereto. 7

(b) Any provision of this Section 9 to the contrary notwithstanding, no adjustment of the Conversion Price shall be made if the amount of such adjustment would be less than One Cent ($0.01) per share; provided, however, that any such adjustment shall be carried forward and an adjustment with respect thereto shall be made at such time, if any, as any subsequent adjustment(s) together with such carried-forward adjustment(s) result in an aggregate adjustment of One Cent ($0.01) or more. (c) Upon any adjustment of the Conversion Price, then and in each such case, other than as provided in paragraph (b) above, the Corporation's chief financial officer shall give written notice thereof to each holder of shares of Series B Preferred Stock at the address of such holder as shown on the books of the Corporation, which notice shall state the Conversion Price resulting from such adjustment, setting forth in reasonable detail the method upon which such calculation is based. 10. General. (a) The Corporation shall not amend, alter or repeal the preferences, special rights or other powers of the Series B Preferred Stock so as to affect adversely the Series B Preferred Stock, without the written consent or affirmative vote of the holders of a majority of the then outstanding shares of Series B Preferred Stock, given in writing or by vote at a meeting, consenting or voting (as the case may be) separately as a class, in accordance with applicable law. Without limiting the generality of the foregoing, the authorization of any shares of capital stock with preference or priority over the Series B Preferred Stock as to the right to receive either dividends or amounts distributable upon liquidation, dissolution or winding up of the Corporation shall be deemed to affect adversely the Series B Preferred Stock, and the authorization of any shares of capital stock on a parity with Series B Preferred Stock as to the right to receive either dividends or amounts disbributable upon liquidation, dissolution or winding up of the Corporation shall not be deemed to affect adversely the Series B Preferred Stock. (b) The number of authorized shares of Series B Preferred Stock may be increased (but only for the purpose of providing a sufficient number of authorized Preferred B Shares for the payment of dividends on outstanding Preferred B Shares) or decreased (but not below the number of shares then outstanding) by the directors of the Corporation. (c) Any of the rights of the holders of Series B Preferred Stock set forth herein may be waived by the affirmative vote of the holders of a majority of the shares of Series B Preferred Stock then outstanding, which vote may be taken by written consent or at a meeting of the holders of Preferred B Shares. 11. Notices. (a) Any notices required to be given to any holder of Series B Preferred Stock shall be deemed properly given if deposited in the United States 8

mail, postage prepaid, or sent by facsimile or by overnight or express delivery service, or by electronic mail or similar electronic transmission, followed by duplicate notice via United States first class mail, postage prepaid, and addressed to the holder of record at such holder's address appearing at the books of the Corporation. (b) In case of any (i) capital reorganization of the Corporation, reclassification, of the capital stock of the Corporation, consolidation or merger of the Corporation with or into another corporation, or conveyance of all or substantially all of the assets of the Corporation to another corporation; (ii) voluntary or involuntary dissolution, liquidation or winding up of the Corporation; or (iii) other event specified in this Certificate of Designations or pursuant to applicable law requiring the taking of such a record, then, and in each such case, the Corporation shall mail or cause to be mailed to each holder of shares of Series B Preferred Stock a notice specifying, as the case may be, the date on which a record is to be taken for the foregoing purposes and providing the information reasonably required in order enable to holders of record of Preferred B Shares to exercise the rights conferred by this Certificate of Designations. SECOND: That such determination of the designation, preferences and the relative, participating, optional or other rights, and the qualifications, limitations or restrictions thereof, relating to said Series B Preferred Stock, was duly made by the Board of Directors pursuant to the provisions of the Certificate of Incorporation of the Corporation, and in accordance with the provisions of Section 151 of the General Corporation Law of the State of Delaware, as amended.

In the event that, after August 6, 2002, Corporation shall (i) declare and pay any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock or (iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the Adjustment Number in effect immediately prior to such event shall be adjusted by multiplying such Adjustment Number by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event. (B) The Corporation shall declare a dividend or distribution on the Series C Junior Participating Preferred Stock as provided in paragraph (A) above immediately after it declares a dividend or distribution on the Common Stock (other than a dividend payable in shares of Common Stock). (C) Dividends shall begin to accrue and be cumulative on outstanding shares of Series C Junior Participating Preferred Stock from the Quarterly Dividend Payment Date next preceding the date of issue of such shares of Series C Junior Participating Preferred Stock, unless the date of issue of such shares is prior to the record date for the first Quarterly Dividend Payment Date, in which case dividends on such shares shall begin to accrue from the date of issue of such shares, or unless the date of issue is a Quarterly Dividend Payment Date or is a date after the record date for the determination of holders of shares of Series C Junior Participating Preferred Stock entitled to receive a quarterly 2

dividend and before such Quarterly Dividend Payment Date, in either of which events such dividends shall begin to accrue and be cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends paid on the shares of Series C Junior Participating Preferred Stock in an amount less than the total amount of such dividends at the time accrued and payable on such shares shall be allocated pro rata on a share-by-share basis among all such shares at the time outstanding. The Board of Directors may fix a record date for the determination of holders of shares of Series C Junior Participating Preferred Stock entitled to receive payment of a dividend or distribution declared thereon, which record date shall be no more than 60 calendar days prior to the date fixed for the payment thereof. 3. Voting Rights. The holders of shares of Series C Junior Participa- ting Preferred Stock shall have the following voting rights: (A) Each share of Series C Junior Participating Preferred Stock shall entitle the holder thereof to a number of votes equal to the Adjustment Number on all matters submitted to a vote of the stockholders of the Corporation. (B) Except as required by law, by Section 3(C) and by Section 10 hereof, holders of Series C Junior Participating Preferred Stock shall have no special voting rights and their consent shall not be required (except to the extent they are entitled to vote with holders of Common Stock as set forth herein) for taking any corporate action. (C) If, at the time of any annual meeting of stockholders for the election of directors, the equivalent of six quarterly dividends (whether or not consecutive) payable on any share or shares of Series C Junior Participating Preferred Stock are in default, the number of directors constituting the Board of Directors of the Corporation shall be increased by two. In addition to voting together with the holders of Common Stock for the election of other directors of the Corporation, the holders of record of the Series C Junior Participating Preferred Stock, voting separately as a class to the exclusion of the holders of Common Stock, shall be entitled at said meeting of stockholders (and at each subsequent annual meeting of stockholders), unless all dividends in arrears on the Series C Junior Participating Preferred Stock have been paid or declared and set apart for payment prior thereto, to vote for the election of two directors of the Corporation, the holders of any Series C Junior Participating Preferred Stock being entitled to cast a number of votes per share of Series C Junior Participating Preferred Stock as is specified in paragraph (A) of this Section 3. Each such additional director shall not be a member of Class I, Class II or Class III of the Board of Directors of the Corporation, but shall serve until the next annual meeting of stockholders for the election of directors, or until his or her successor shall be elected and shall qualify, or until his or her right to hold such office terminates pursuant to the provisions of this Section 3(C). Until the default in payments of all dividends which permitted the election of said directors shall cease to exist, any director who shall have been so elected pursuant to the provisions of this Section 3(C) may be removed at any time, without cause, only by the affirmative vote of the holders of the 3

shares of Series C Junior Participating Preferred Stock at the time entitled to cast a majority of the votes entitled to be cast for the election of any such director at a special meeting of such holders called for that purpose, and any vacancy thereby created may be filled by the vote of such holders. If and when such default shall cease to exist, the holders of the Series C Junior Participating Preferred Stock shall be divested of the foregoing special voting rights, subject to revesting in the event of each and every subsequent like default in payments of dividends. Upon the termination of the foregoing special voting rights, the terms of office of all persons who may have been elected directors pursuant to said special voting rights shall forthwith terminate, and the number of directors constituting the Board of Directors shall be reduced by two. The voting rights granted by this Section 3(C) shall be in addition to any other voting rights granted to the holders of the Series C Junior Participating Preferred Stock in this Section 3. 4. Certain Restrictions. (A) Whenever quarterly dividends or other dividends or distributions payable on the Series C Junior Participating Preferred Stock as provided in Section 2 are in arrears, thereafter and until all accrued and unpaid dividends and distributions, whether or not declared, on shares of Series C Junior Participating Preferred Stock outstanding shall have been paid in full, the Corporation shall not: (i) declare or pay dividends on, make any other distributions on, or redeem or purchase or otherwise acquire for consideration any shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series C Junior Participating Preferred Stock; (ii) declare or pay dividends on or make any other distributions on any shares of stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series C Junior Participating Preferred Stock, except dividends paid ratably on the Series C Junior Participating Preferred Stock and all such parity stock on which dividends are payable or in arrears in proportion to the total amounts to which the holders of all such shares are then entitled; or (iii) purchase or otherwise acquire for consideration any shares of Series C Junior Participating Preferred Stock, or any shares of stock ranking on a parity with the Series C Junior Participating Preferred Stock, except in accordance with a purchase offer made in writing or by publication (as determined by the Board of Directors) to all holders of Series C Junior Participating Preferred Stock, or to such holders and holders of any such shares ranking on a parity therewith, upon such terms as the Board of Directors, after consideration of the respective annual dividend rates and other relative rights and preferences of the respective series and classes, shall determine in good faith will result in fair and equitable treatment among the respective series or classes. 4

(B) The Corporation shall not permit any subsidiary of the Corporation to purchase or otherwise acquire for consideration any shares of stock of the Corporation unless the Corporation could, under paragraph (A) of this Section 4, purchase or otherwise acquire such shares at such time and in such manner. 5. Reacquired Shares. Any shares of Series C Junior Participating Preferred Stock purchased or otherwise acquired by the Corporation in any manner whatsoever shall be retired promptly after the acquisition thereof. All such shares shall upon their retirement become authorized but unissued shares of Preferred Stock and may be reissued as part of a new series of Preferred Stock to be created by resolution or resolutions of the Board of Directors, subject to any conditions and restrictions on issuance set forth herein. 6. Liquidation, Dissolution or Winding Up. (A) Upon any liquidation, dissolution or winding up of the Corporation, voluntary or otherwise, no distribution shall be made to the holders of shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series C Junior Participating Preferred Stock unless, prior thereto, the holders of shares of Series C Junior Participating Preferred Stock shall have received an amount per share (the "Series C Liquidation Preference") equal to the greater of (i) $100 plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such payment, or (ii) the Adjustment Number times the per share amount of all cash and other property to be distributed in respect of the Common Stock upon such liquidation, dissolution or winding up of the Corporation. (B) In the event, however, that there are not sufficient assets available to permit payment in full of the Series C Liquidation Preference and the liquidation preferences of all other classes and series of stock of the Corporation, if any, that rank in parity with the Series C Junior Participating Preferred Stock in respect thereof, then the assets available for such distribution shall be distributed ratably to the holders of the Series C Junior Participating Preferred Stock and the holders of such parity shares in proportion to their respective liquidation preferences. (C) Neither the merger or consolidation of the Corporation into or with another entity nor the merger or consolidation of any other entity into or with the Corporation shall be deemed to be a liquidation, dissolution or winding up of the Corporation within the meaning of this Section 6. 7. Consolidation, Merger, Etc. In case the Corporation shall enter into any consolidation, merger, combination or other transaction in which the outstanding shares of Common Stock are exchanged for or changed into other stock or securities, cash and/or any other property, then in any such case each share of Series C Junior Participating Preferred Stock shall at the same time be similarly exchanged or changed in an amount per share equal to the Adjustment Number times the aggregate amount of stock, securities, cash and/or any other property (payable in kind), as the case may be, into which or for which each share of Common Stock is changed or exchanged. 5

8. No Redemption. Shares of Series C Junior Participating Preferred Stock shall not be subject to redemption by the Corporation. 9. Ranking. The Series C Junior Participating Preferred Stock shall rank junior to all other series of the Preferred Stock as to the payment of dividends and as to the distribution of assets upon liquidation, dissolution or winding up, unless the terms of any such series shall provide otherwise, and shall rank senior to the Common Stock as to such matters. 10. Amendment. At any time that any shares of Series C Junior Participating Preferred Stock are outstanding, the Certificate of Incorporation of the Corporation shall not be amended in any manner which would materially alter or change the powers, preferences or special rights of the Series C Junior Participating Preferred Stock so as to affect them adversely without the affirmative vote of the holders of two-thirds of the outstanding shares of Series C Junior Participating Preferred Stock, voting separately as a class. 11. Fractional Shares. Series C Junior Participating Preferred Stock may be issued in fractions of a share that shall entitle the holder, in proportion to such holder's fractional shares, to exercise voting rights, receive dividends, participate in distributions and to have the benefit of all other rights of holders of Series C Junior Participating Preferred Stock.

                             Void after June 1, 2007


         1.  Warrant to Purchase Common Stock.      Serial Number:
             --------------------------------

             1.1  Warrant  to  Purchase  Shares.  This  warrant  (this  "Initial
Warrant") certifies that, for good and valuable  consideration,  the receipt and
sufficiency of which is hereby  acknowledged,  __________________  (the "Warrant
Holder") is entitled,  effective as of June 1, 2002 (the "Issue Date"),  subject
to the terms and  conditions of this Initial  Warrant,  to purchase from Celsion
Corporation,   a  Delaware  corporation  (the  "Company"),  up  to  a  total  of
________________  (__________)  shares of the Common Stock of the  Company,  par
value One Cent ($0.01) per share (each, a "Warrant Share" and, collectively, the
"Warrant  Shares"),  at a purchase  price (the  "Exercise  Price") of Sixty-Five
Cents  ($0.65)  per  Warrant  Share,  at any time prior to 5:00 p.m.  prevailing
Eastern time on June 1, 2007 (the  "Expiration  Date").  The Warrant (as defined
below) must be exercised,  if at all, in whole or in part, any time on or before
the Expiration  Date,  subject to earlier  redemption by the Company as provided
herein. Unless the context otherwise requires,  the term "Shares" shall mean and
include the Common Stock of the Company and other securities and property at any
time  receivable  or  issuable  upon  exercise  of this  Initial  Warrant or any
Additional  Warrant issued pursuant  hereto.  The term "Warrant" as used herein,
shall include this Initial Warrant,  any Additional  Warrants (as defined below)
issued pursuant hereto,  and any warrants  delivered in substitution or exchange
therefor as provided herein.

             1.2  Contingent Issuance of Warrants to Purchase Additional Shares.
                  --------------------------------------------------------------
                  (a) In the event  that the high  sales  price  for the  Common
Stock as reported on the American Stock Exchange or other national market and/or
over-the-counter  market, as then constitutes the primary exchange on or through
which the Common Stock then is traded, has not exceeded $0.65 per share (subject
to adjustment  for stock splits,  stock  dividends,  recapitalizations,  and the
like) for any period of at least ten (10) consecutive trading days commencing on
or after the Issue Date and ending on the 90th calendar day following such Issue
Date (or, if such 90th day is not a trading day,  ending on the next  succeeding
business day) (the "First  Measurement  Date"),  then immediately  subsequent to
such First  Measurement  Date the Company  shall issue to the Warrant  Holder an
additional Warrant (an "Additional  Warrant") providing for the purchase of that
number of Warrant Shares equal to one-half (1/2) of the number of Warrant Shares
originally subject to this Warrant.


(b) In the event that the Company is required to issue an Additional Warrant in accordance with subsection (a) above and the high sales price for the Common Stock as reported on the American Stock Exchange or other national market and/or over-the-counter market, as then constitutes the primary exchange on or through which the Common Stock then is traded, has not exceeded $0.65 per share (subject to adjustment for stock splits, stock dividends, recapitalizations, and the like) for any period of at least ten (10) consecutive trading days commencing on or after the First Measurement Date and ending on the 180th calendar day following the Issue Date (or, if such 180th day is not a trading day, ending on the next succeeding business day) (the "Second Measurement Date"), then immediately subsequent to such Second Measurement Date the Company shall issue to the Warrant Holder an Additional Warrant providing for the purchase of that number of Warrant Shares equal to two-thirds (2/3) of the number of Warrant Shares originally subject to this Warrant. (c) In the event that the Company is required to issue Additional Warrants in accordance with subsection (a) and subsection (b) above and the high sales price for the Common Stock as reported on the American Stock Exchange or other national market and/or over-the-counter market, as then constitutes the primary exchange on or through which the Common Stock then is traded, has not exceeded $0.65 per share (subject to adjustment for stock splits, stock dividends, recapitalizations and the like) for any period of at least ten (10) consecutive trading days commencing on or after the Second Measurement Date and ending on the 270th calendar day following the Issue Date (or, if such 270th day is not a trading day, ending on the next succeeding business day) (the "Third Measurement Date"), then immediately subsequent to such Third Measurement Date the Company shall issue to the Warrant Holder an Additional Warrant providing for the purchase of that number of Warrant Shares equal to five-sixths (5/6) of the number of Warrant Shares originally subject to this Warrant. (d) Any Additional Warrant(s) issued as provided in this Section 1.2 shall be identical, as to terms, to this Initial Warrant and shall differ only in the number of Shares covered thereby and in that Additional Warrants shall not provide for the issuance of Additional Warrants. 1.3 Adjustment of Exercise Price and Number of Shares. The number and character of the Warrant Shares and the Exercise Price therefor, are subject to adjustment upon occurrence of the following events: (a) Adjustment for Stock Splits, Stock Dividends, Recapitalizations, and the like. The Exercise Price of this Warrant and the number of Shares issuable upon exercise of this Warrant shall each be proportionally adjusted to reflect any stock dividend, stock split, reverse stock split, combination of shares, reclassification, recapitalization or other similar event altering the number of outstanding shares of the Company's Common Stock. (b) Adjustment for Capital Reorganization, Consolidation, Merger. If any reorganization of the capital stock of the Company, any consolidation or merger of the Company with or into another corporation, or the sale of all or substantially all of the Company's assets to another corporation shall be effected in such a way that holders of the Company's Common Stock will 2

be entitled to receive stock, securities or assets with respect to or in exchange for the Company's Common Stock, then in each such case the Warrant Holder, upon the exercise of the Warrant at any time after the consummation of such capital reorganization, consolidation, merger, or sale, shall be entitled to receive, in lieu of the stock or other securities and property receivable upon the exercise of the Warrant prior to such consummation, the stock or other securities or property to which such Warrant Holder would have been entitled upon such consummation if such Warrant Holder had exercised this Warrant immediately prior to the consummation of such capital reorganization, consolidation, merger, or sale, all subject to further adjustment as provided in this Section 1.3; and in each such case, the terms of this Warrant shall be applicable to the shares of stock or other securities or property receivable upon the exercise of this Warrant after such consummation. 2. Manner of Exercise. ------------------ 2.1 Warrant Exercise Agreement. This Warrant may be exercised, in whole or in part, on any business day on or prior to the Expiration Date, subject to earlier redemption by the Company as provided herein. To exercise this Warrant, the Warrant Holder must surrender to the Company this Warrant and deliver to the Company: (a) a duly executed exercise agreement in the form attached hereto as Exhibit A, or in such other form as may be approved by the Company from time to time (the "Warrant Exercise Agreement"); and (b) payment in full of the Exercise Price for the number of Warrant Shares to be purchased upon exercise hereof (the "Aggregate Exercise Price"). If someone other than the Warrant Holder exercises this Warrant, then such person must submit to the Company each of the items set forth in clauses (a) and (b) of the foregoing sentence and, in addition, must submit (c) documentation acceptable to the Company that such person has the right to exercise this Warrant and (d) if applicable, a spousal consent in the form attached hereto as Exhibit B. Upon a partial exercise, this Warrant shall be surrendered, and a new warrant of the same tenor for purchase of the number of remaining Warrant Shares not previously purchased shall be issued by the Company to the Warrant Holder. This Warrant shall be deemed to have been exercised as of the close of business on the date of its surrender or, if such date is not a business day, then as of the close of business on the next succeeding business day, for exercise as provided above, and the person entitled to receive the Warrant Shares issuable upon such exercise shall be treated for all purposes as the holder of record of such Warrant Shares as of the close of business on such deemed exercise date. 2.2 Limitations on Exercise. This Warrant may not be exercised as to fewer than One Hundred (100) Warrant Shares, unless it is exercised as to all Warrant Shares as to which this Warrant is then exercisable and in no event may this Warrant be issued other than for a whole number of Warrant Shares. 2.3 Payment. The Warrant Exercise Agreement shall be accompanied by full payment of the Aggregate Exercise Price for the Warrant Shares being purchased, in cash, by certified or cashier's check, wire transfer or other immediately available funds. 3

2.4 Tax Withholding. Prior to the issuance of the Warrant Shares upon exercise of this Warrant, the Warrant Holder must pay or provide for any applicable federal or state withholding obligations of the Company. 2.5 Issuance of Shares. Provided that the Warrant Exercise Agreement, any other documentation required hereby and payment as required hereby have been received by the Company as provided above, the Company shall issue the Warrant Shares (adjusted as provided herein) purchased pursuant to such exercise, registered in the name of the Warrant Holder, the Warrant Holder's authorized assignee or the Warrant Holder's legal representative, and shall deliver one or more certificates representing the Warrant Shares as the Warrant Holder reasonably may request with the appropriate legends affixed thereto. 3. Registration Rights. The Warrant Shares will have the registration rights as provided for in Section 4 of the Subscription Agreement entered into between the Company and the Warrant Holder in connection with the issuance and purchase of this Warrant (the "Subscription Agreement"). 4. Redemption. The Company, at its sole discretion, may, at any time and from time to time after September 3, 2002, redeem and cancel all or any part of the Warrant then outstanding upon the payment of consideration consisting of One Cent ($0.01) for each Warrant Share subject to this Warrant redeemed and cancelled; provided, however, that any such redemptions and cancellations may be made by the Company only upon thirty (30) calendar days' prior written notice (the "Redemption Date" being the close of business on the 30th day following the date the notice is deemed to be given to the Warrant Holder pursuant to Section 9 hereof) and only if the closing sales price for a share of the Company's Common Stock as reported on the American Stock Exchange or other national market and/or over-the-counter market, as then constitutes the primary exchange on or through which the Common Stock then is traded, has been equal to or greater than Two Dollars ($2.00) for any period of at least ten (10) consecutive trading days commencing on or after the Issue Date; and provided, further, that any Warrant Holder subject to such redemption and cancellation may exercise such Warrant at any time prior to the expiration of the thirty (30)-day notice period; and provided further that the Company's right to redeem and cancel the Warrant shall be suspended in the event the shelf registration statement required under Section 4 of the Subscription Agreement is subject to a stop order or is otherwise not in effect or if the Warrant Holder is advised under Section 4(c) of the Subscription Agreement that the prospectus included in such shelf registration statement contains a material misstatement or omission during any portion of the thirty (30)-day notice period, with such suspension to terminate and the Company's right to redeem and cancel to be reinstated on the date following the date on which (i) a registration statement covering the Warrant Shares is effective and not subject to any stop order and (ii) the Company has delivered to the Warrant Holder a prospectus covering the Warrant Shares of such Warrant Holder under Section 4(c) of the Subscription Agreement. The notice period shall then be extended for a period equal to the number of days during the notice period during which registration was not effective or the prospectus was not available or contained a material misstatement or omission. If less than all of the outstanding Warrants are redeemed and cancelled, Warrants shall be redeemed and cancelled on a pro rata basis. 4

5. Compliance with Laws and Regulations. The issuance, transfer and exercise of this Warrant and the issuance and transfer of the Warrant Shares shall be subject to compliance by the Company and the Warrant Holder with all applicable requirements of federal and state securities laws and with all applicable requirements of any stock exchange and/or over-the-counter market on which the Company's Common Stock may be listed at the time of such issuance or transfer. 6. Transfer and Exchange.

         Re:      Registration for Resale of 10,036,000 Shares
                  of Common Stock for Resale on Form S-3
                  --------------------------------------------

Ladies and Gentlemen:

         We have acted as counsel to Celsion Corporation, a Delaware corporation
(the "Registrant"), in connection with a registration statement on Form S-3 (the
"Registration Statement") filed this day with the Securities and Exchange
Commission (the "Commission") pursuant to the Securities Act of 1933, as amended
(the "Securities Act"), pertaining to the registration for resale, by certain
securityholders named in the Registration Statement, of up to 10,036,000 shares
(the "Registration Shares") of common stock, par value $0.01 per share ("Common
Stock"), of the Registrant, consisting of (a) 3,243,000 currently outstanding
shares of Common Stock (the "Common Stock Placement Shares"), (b) up to
3,193,000 shares of Common Stock (the "Series B Conversion Shares") issuable
upon conversion of shares of the Registrant's Series B 8% Convertible Preferred
Stock, par value $.01 per share (the "Series B Preferred Shares") and (c) up to
3,600,000 shares of Common Stock (the "Warrant Shares") underlying Common Stock
purchase warrants, of which warrants to purchase 1,800,000 shares of Common
Stock are outstanding as of the date hereof and warrants to purchase an
additional 1,800,000 are subject to contingent issuance under certain
circumstances.

         This  opinion  letter  is  being   furnished  in  accordance  with  the
requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

         For the purpose of rendering our opinions as expressed  herein, we have
been furnished and have reviewed the following documents:

Certificate  of  Designations")  and  the  Certificate  of  Designations  of the

(collectively, the "Certificate of Incorporation");

                  (ii) the bylaws of the  Registrant,  as amended through and in
effect as of the date hereof (the "Bylaws");

                  (iii) the Registration Statement;

                  (iv)  a  form  of   subscription   agreement  (the  "Series  B

each such unit  consisting  of (a) one (1)  share of the  Registrant's  Series B

Registrant's  Series B Conversion  Shares and (b) one (1) warrant to acquire 600
Warrant Shares,  subject to issuance of additional  warrants (up to a maximum of

                  (v) a form of the Series B Unit Warrant;

                  (vi) a form  of  subscription  agreement  (the  "Common  Stock

                  (viii) a certificate  of the Secretary of State as to the good
standing of the Registrant; and

                  (ix) a  certificate  of an  officer  of the  Registrant  as to
certain matters (the "Officer's Certificate").

         In our  examination,  we have assumed the legal capacity of all natural
persons,  the genuineness of all signatures,  the  authenticity of all documents
submitted  to us as  originals,  the  conformity  to original  documents  of all
documents submitted to us as certified,  conformed or photostatic copies and the
authenticity  of the originals of such latter  documents.  In our examination of
documents  executed or to be executed by parties other than the Registrant,  its
directors and officers, we have assumed that such parties had, have or will have
the  power,  corporate  or other,  to enter  into and  perform  all  obligations
thereunder and have also assumed the due  authorization by all requisite action,
corporate or other, and execution and delivery by such parties of such documents
and the validity and binding  effect  thereof.  For the purpose of rendering our
opinions as expressed  herein,  we have not reviewed any document other than the
documents  set forth above,  and we assume there exists no provision of any such
other document that bears upon or is inconsistent with our opinions as expressed
herein. We have conducted no independent  factual  investigation of our own, but
rather have relied  solely upon the  foregoing  documents,  the  statements  and
information  set forth therein,  and the additional  matters  recited or assumed
herein, all of which we assume to be true, complete and accurate in all material
respects.

         In addition to the foregoing, for the purpose of rendering our opinions
as expressed herein, we have, with your consent, assumed the following matters:

                  (1) that (a) each Series B Subscription  Agreement conforms in
all material respects to the form of Series B Subscription  Agreement  furnished
for our review, (b) each Common Stock Placement  Subscription Agreement conforms
in all  material  respects to the form of Common  Stock  Placement  Subscription
Agreement  furnished for our review and (c) each Series B Unit Warrant  conforms
in all material  respects to the form of the Series B Unit Warrant furnished for
our review;

                  (2) that each of the Series B Subscription Agreements, each of
the Common Stock  Placement  Subscription  Agreements,  and each of the Series B
Unit  Warrants has been duly  authorized,  executed and delivered by each of the
parties thereto;

                  (3) that the Registrant has received or will receive, prior to
the  time of  issuance  of the  Series B  Preferred  Shares,  the  Series B Unit
Warrants,  the Series B  Conversion  Shares,  the Warrant  Shares and the Common
Stock Placement  Shares,  as applicable,  the entire amount of the consideration
contemplated  by  (a)  the  Series  B  Subscription  Agreement,   the  Series  B
Certificate  of  Designations,  the Series B Unit  Warrant  or the Common  Stock
Placement Subscription  Agreement, as the case may be and (b) the resolutions of
the Board (i)  authorizing  the issuance of the Series B Preferred  Shares,  the
Series B Unit Warrants,  the Series B Conversion  Shares, the Warrant Shares and
the Common Stock Placement Shares and (ii) approving the Series B Certificate of
Designations,  the Series B Subscription  Agreement,  the Series B Unit Warrants
and the Common Stock Placement Subscription Agreement;

                  (4)  that  the  Registrant   has  and  will  have   sufficient
authorized,  unissued and otherwise  unreserved shares of Common Stock available
for issuance at the time of each issuance of Registration Shares;

                  (5)  that  the  relevant  provisions  of  the  Certificate  of
Incorporation,  the  Bylaws  and the  General  Corporation  Law of the  State of
Delaware  (the  "DGCL")  in  effect  at  the  time  of  issuance  of  any of the
Registration  Shares did not or will not differ in any relevant respect from the
analogous  provisions of the  Certificate of  Incorporation,  the Bylaws and the
DGCL in  effect as of the date of this  opinion  letter  and that no  additional
relevant provisions shall have been added subsequent to the date hereof;

                  (6)  that  stock   certificates  (the  "Stock   Certificates")
representing  the  Common  Stock,  in the  form  attached  as  Exhibit  E to the
Officer's  Certificate,  have  been  or will be  duly  completed,  executed  and
delivered by the President  and the Secretary of the  Registrant to reflect each
due and valid issuance of any Registration Shares;

                  (7) that no Registration Shares shall be issued at a per share
price less than the par value thereof; and

                  (8) that each issuance Registration Shares has been or will be
recorded  properly  in the stock  ledger of the  Registrant  at the time of such
issuance.

         Based  upon and  subject to the  foregoing  and upon our review of such
matters of law as we have deemed  necessary and  appropriate  in order to render
our opinions as expressed herein,  and subject to the assumptions,  limitations,
exceptions and  qualifications  set forth herein, it is our opinion (a) that the
Registration  Shares  have  been  duly  authorized,  (b) that the  Common  Stock
Placement  Shares have been validly issued and are fully paid and  nonassessable
and (c) that,  when issued,  delivered and paid for in accordance with the terms
of the Series B Certificate of  Designations  or the Series B Unit Warrants,  as
the case may be, the Series B Conversion  Shares and the Warrant  Shares will be
validly issued, fully paid and nonassessable.

         This letter  expresses  our opinions  with respect to the DGCL (without
regard to the principles of conflict of laws thereof)  governing matters such as
due organization and the authorization and issuance of stock as such laws are in
effect  as of the  date  hereof,  as well  as the  pertinent  provisions  of the
Delaware  Constitution,  and reported judicial decisions  interpreting such laws
related to the  matters set forth  herein as in effect as of such date.  It does
not extend to the securities or "blue sky" laws of any jurisdiction,  to federal
securities  laws,  to the laws of  contract  or to any  other  laws of any other
jurisdiction  or the rules and  regulations  of stock  exchanges or of any other
regulatory  body and we do not express any opinion as to the effect of any other
laws on the  opinions  stated  herein.  We assume no  obligation  to update  the
opinions set forth herein.

         We hereby  consent to the use of and filing of this opinion  letter and
the opinions expressed herein as an exhibit to the Registration Statement and to
the use of our name under the caption  "Legal  Matters" in the  prospectus  that
forms a part of the Registration  Statement,  provided,  however, that in giving
such consent we do not admit that we come within the  category of persons  whose
consent  is  required  under  Section 7 of the  Securities  Act or the rules and

in any other manner without, in each instance, our prior written consent.

                                 Very truly yours,
