The Delcath System Procedure Isolating the Liver For Chemotherapy Treatment. 1. An infusion catheter is inserted into the artery through which blood normally flows to the liver. 2. A second catheter -- the Delcath double balloon catheter -- is inserted through the inferior vena cava. Blood normally flows from the liver into the inferior vena cava to the heart which circulates the blood throughout the body. [Diagram of interior cross section 3. The balloons on the double balloon of a human torso showing the catheter are then inflated. This prevents liver, heart and major arteries the normal flow of blood from the liver and veins.

Blood exits the liver through perforations on the double balloon catheter and flows into this catheter out of the body. 6. Once out of the body, the infused blood is circulated through activated charcoal filters to remove most of the chemotherapeutic agent. 7. The filtered blood is returned to the patient through the jugular vein which leads to the superior vena cava and the heart. The heart restores the cleansed blood to normal circulation. 5.

PROSPECTUS SUMMARY This is a summary of the information contained in this prospectus. To understand this offering fully, you should read the entire prospectus, especially the risk factors. Unless the context indicates to the contrary, all per share data and information relating to our common stock gives effect to a one-for-2.2881 reverse stock split of our common stock which will occur immediately before the date of this prospectus. Unless the context indicates to the contrary, the terms "Delcath," "we," "us," and "our" refer to Delcath Systems, Inc. Our Business Delcath has developed a system to isolate the liver from the general circulatory system and to administer chemotherapy and other therapeutic agents directly to the liver. Using the Delcath system, blood flowing into the liver, after being infused with chemotherapy agents, is redirected out of the patient's body, passed through filters which remove most of the chemotherapy agents and then returned to the patient's general circulatory system. Isolating the liver and cleansing the blood before its return into the patient's circulatory system protects other parts of the body from the harmful side-effects of chemotherapy. We believe that the use of the Delcath system in treatment of liver cancer will allow higher dosages of chemotherapy to be administered to the liver than can be administered with conventional intravenous delivery. The Delcath system is not currently approved for marketing by the United States Food and Drug Administration, and it cannot be marketed in the United States without FDA approval. With the proceeds of this offering, we plan to conduct Phase III clinical trials under protocols which have been approved by the FDA and which are designed to secure FDA marketing approval for the Delcath system in the United States. The Phase III trials will seek to demonstrate the safety and efficacy of the Delcath system in administering the chemotherapy agent, doxorubicin, to treat cancerous tumors that have originated in the liver, commonly known as, primary liver cancer, and cancerous tumors from malignant melanoma that have spread to the liver. If the trials are successful and the FDA approves the Delcath system for commercial sale, we will be authorized to market the Delcath system for use with doxorubicin in the United States to treat primary liver cancer and melanoma which has spread to the liver. We will also seek regulatory approval to market the Delcath system for commercial sale in Asian countries, where there is a particularly high incidence of liver cancer, as well as in Europe and Latin America. We believe that the Delcath system may provide cost savings in the treatment of liver cancer to the extent that it can reduce treatment and hospitalization costs associated with the side effects of chemotherapy. Delivered as a disposable kit containing a series of catheters, including our patented double balloon catheter, and a blood filtration system, the Delcath system is designed to be minimally invasive and fit well within the techniques currently employed by interventional radiologists. In addition, we believe that the technology used in the Delcath system may be used with other chemotherapy agents to treat other cancers that have spread to the liver and to treat cancers in other parts of the body. Our Market Opportunity Liver cancer is the third most common form of cancer, with a worldwide incidence of primary liver cancer estimated to be 1,000,000 new patients per year and an estimated 1,250,000 deaths worldwide caused by all forms of liver cancer. The American Cancer Society has projected that in the United States there will be approximately 15,300 new cases of primary liver cancer and 47,700 new cases of malignant melanoma in 2000. Corporate Information We were incorporated in Delaware on August 5, 1988 under the name BGH Medical Products. On May 7, 1990 we changed our name to Delcath Systems, Inc. Our executive offices are located at 1100 Summer Street, Stamford, Connecticut 06905. Our telephone number at this location is (203) 323-8668. 3

RISK FACTORS The shares offered by this prospectus are speculative and involve a high degree of risk. In addition to other information in this prospectus, you should consider carefully the following risks before making an investment decision. Risks related to our financial condition We have a history of losses and we expect to incur increased losses. From our inception on August 5, 1988 through March 31, 2000, we have incurred cumulative losses of $11,522,086, substantially all of which were incurred in connection with our product development efforts. For the years ended December 31, 1998 and December 31, 1999 we incurred net losses of $2,049,980 and $572,581. We expect to continue to incur significant and increasing losses while generating minimal revenues over the next few years. Our future profitability will depend on our ability to successfully complete Phase III clinical trials of our Delcath system, obtain FDA pre-marketing approval for the system and successfully market it in the United States and internationally. The proceeds of this offering may not be sufficient to complete our Phase III clinical trials and obtain FDA approval for the use of doxorubicin with our Delcath system. Based upon our assumptions, we expect that the net proceeds of this offering will enable us to complete our Phase III clinical trials and obtain FDA approval for the use of doxorubicin with our Delcath system. We cannot assure you that the proceeds of this offering will be sufficient for these purposes because of unanticipated delays or expenses, increased regulatory requirements by the FDA or other factors which we cannot foresee or control. If we do not obtain any financing that we may require, we will not be able to complete Phase III clinical trials and obtain FDA approval for the Delcath system which could result in the cessation of our business and the loss of your entire investment. We will require significant additional capital to commercialize the Delcath system. The proceeds of this offering will be insufficient to fund the costs of commercializing the Delcath system. We will require significant additional capital to fund the costs associated with widescale marketing of the Delcath system. We have no commitments for any additional financing. If we are unable to obtain additional financing as needed, we will not be able to sell the system on a commercial scale and our business will be adversely impacted. Risks related to FDA and foreign regulatory approval If Phase III clinical trials prove unsuccessful, we will be unable to obtain FDA marketing approval and will be unable to sell the Delcath system in the United States. We cannot market or sell the Delcath system in the United States without FDA marketing approval. If Phase III clinical trials are unsuccessful, we will be unable to provide the FDA with the clinical data required to demonstrate that the Delcath system is safe and efficacious and to obtain approval to market the Delcath system in the United States. If we are unable to market the Delcath system in the United States, it is likely that our business will cease, resulting in the loss of your entire investment. The FDA may reject the results of our clinical trials in whole or in part, which could result in the FDA refusing to grant marketing approval or limiting the circumstances under which the Delcath system may be used. Marketing approval requires a determination by the FDA that the data developed by our clinical trials shows that the use of doxorubicin in our system is safe and effective in the treatment of primary liver cancer and melanoma which has spread to the liver. The FDA requires that we demonstrate, in a statistically rigorous manner, increased patient survival times for approval of our pre-market application. If regulatory approval is granted, approval may require limitations on the indicated uses for which the Delcath system may be 6

marketed. Failure to obtain FDA approval to market the Delcath system, or obtaining FDA approval with substantial limitations on its indicated uses, would have a material adverse effect on our business, financial condition and results of operations, and could result in the cessation of our business and the loss of your entire investment. If we do not obtain FDA marketing approval, we may not be able to sell the Delcath System in foreign markets. If we do not obtain FDA marketing approval because our clinical trials are unsuccessful, we may not be able to obtain regulatory approval to market the Delcath system in foreign markets. In the absence of FDA approval, even if we obtain approval from foreign regulatory agencies, we will not be able to export the Delcath system from the United States unless approval has been obtained from one of a number of developed industrialized nations. We have not begun to seek foreign regulatory approval and may not be able to obtain approval from one of those designated nations. If we are unable to market the Delcath system internationally, our market opportunity will be materially limited. We do not expect to receive FDA approval for 24 months from the closing of this offering. We expect that once Phase III clinical trials begin, they will take at least 12 months to complete. We expect to begin the clinical trials during the fourth quarter of 2000. However, we may experience delays in beginning, conducting and completing the trials because of delays in designing the trials to conform to the trial protocols and the requirements of investigational review boards at the sites where the trials will be conducted. In addition, the rate at which the clinical trials are completed depends upon a number of factors, including our ability to identify clinical test sites and sponsoring physicians and the ability of the clinical test sites to identify patients to enroll in the trials. Further, the FDA monitors the progress of the clinical trials and may alter, suspend or terminate the trials based on the data that has been accumulated to that point and its assessment of the relative risks and benefits to the patients involved in the trials. Any of these factors could result in delay in completing our trials. After acquiring sufficient data, we believe that our collation, analysis and submission of the trial results to the FDA will take an additional three months. Once we submit the data from the clinical trials to the FDA, we estimate that the FDA will respond to our submission within three months. However, the FDA may take longer than three months to evaluate our submission and may require that additional trials be conducted. We have only limited experience in arranging for clinical trials and in evaluating and submitting the data gathered from clinical trials. Further, we cannot control when the FDA will respond to our submission. Any significant delay in completing clinical trials or in the FDA responding to our submission or a requirement by the FDA for us to conduct additional trials will delay the commercialization of the Delcath system. The success and timing of our trials will depend, in part, on the third parties we hire to conduct, and patients which participate in, the Phase III clinical trials. We will rely on third-party contract research organizations, hospitals and other research institutions to conduct the Phase III clinical trials. We are also dependent on a sufficient number of patients agreeing to participate in our trials. Dependence on third parties may result in delays in completing, or the failure to complete, our clinical trials. There is risk that hospitals and research institutions will not approve the conduct of trials at their facilities and that contract research organizations will fail to meet their contractual obligations or fail to meet regulatory standards in the performance of their obligations. The contract research organizations and physicians conducting the clinical trials are not our employees. As a result, we have limited control over their activities and can expect that only limited amounts of their time will be dedicated to the clinical trials. Failure of the research organizations to perform as expected or failure of a sufficient number of patients to volunteer for our trials could result in a delay in completing the trials, submitting our trial results to the FDA, obtaining FDA approval and/or commercializing the Delcath system. 7

The process of obtaining FDA approval for using the Delcath system with other chemotherapy agents and for treatment of other diseases will require significant additional time and financing. The FDA approval we are currently seeking is limited to the treatment of liver cancer patients through administration of doxorubicin with our Delcath system. If we are granted this approval, we plan to subsequently seek additional FDA approvals for using the Delcath system with other chemotherapy agents for treatment of other liver cancers and with anti-viral drugs for treatment of other diseases, such as hepatitis. In many instances, the process of applying for and obtaining regulatory approvals involves rigorous pre-clinical and clinical testing. The time resources and funds required for completing necessary testing and obtaining approvals is significant, and FDA approval may never be obtained for some medical devices or drug delivery systems. If we fail to raise the additional capital required or enter into strategic partnerships to finance this testing or if we fail to obtain the required approvals, our potential growth and the expansion of our business would likely be limited. Even if our Delcath system is approved by the FDA, we will remain subject to extensive regulation. The manufacturing, assembly, labeling, marketing, distribution and advertising of products and treatment methods like the Delcath system is subject to extensive regulation by federal, state and local government regulatory authorities in the United States and other countries. Even if FDA approval is granted to our Delcath system, we will still be subject to stringent regulations, including medical device quality system regulation and good manufacturing practice, which include testing, design, quality control and documentation procedures. Compliance with applicable regulatory requirements is subject to continual review and may be monitored through periodic inspections by the FDA. Similarly, sales of the Delcath system outside of the United States are also subject to manufacturing standards promulgated by the International Standards Organization. In addition, if Delcath assumes responsibility for assembly of its system, those activities will be subject to regulation and control under the Occupational Safety and Health Act. Discovery of previously unknown problems with a product, manufacturer or facility, or failure to comply with regulatory requirements, may result in restrictions on a product or a manufacturer, including substantial fines, suspensions of marketing approval and refusal to grant approval to new products, injunctions, seizures, recalls of products, operating restrictions, civil penalties and criminal charges against us. Third-party reimbursement may not be available to purchasers of the Delcath system, or may be inadequate, which would hamper our sales efforts. Our ability to commercialize the Delcath system in the United States and in foreign markets, if regulatory approval of the system is obtained, will depend, in part, on the extent to which third-party reimbursement for the cost of the Delcath system will be available to purchasers. Physicians, hospitals and other health care providers may be reluctant to purchase our products if they do not receive substantial reimbursement for the cost of the procedures using our products from third-party payors, including Medicare, Medicaid and private health insurance plans. Because the Delcath system currently is characterized by the FDA as an experimental device, its use is not reimbursable in the United States. We will not begin to seek to have third-party payors reimburse the use of the Delcath system until after its use is approved by the FDA. Each third-party payor independently determines whether and to what extent to reimburse for a medical procedure or product. We cannot assure you that third-party payors in the United States or abroad will cover procedures using the Delcath system. Further, third-party payors may deny reimbursement if they determine that the Delcath system was not used in accordance with established payor protocols regarding cost effective treatment methods, or was used for forms of cancer or with drugs not specifically approved by the FDA. Risks related to manufacturing, commercialization and market acceptance of the Delcath system. Because manufacturers must demonstrate compliance with specifications by the FDA, if we change any manufacturer, the completion of the clinical trials and/or the commercialization of the Delcath system would likely be delayed. Manufacturers of the components of the Delcath system must demonstrate to the FDA that these components are manufactured in accordance with manufacturing and performance specifications for the 8

Delcath system on file with the FDA. In the case of the double balloon catheter, in particular, this process can be time consuming. Many of the components of the Delcath system are manufactured by sole-source suppliers. The completion of the clinical trials and/or the commercialization of the Delcath system will likely be delayed if it becomes necessary for us to change any manufacturer. We may not be able to obtain adequate supplies of components for the Delcath system. We do not have any contracts with suppliers for the manufacture of components for the Delcath system. To date, we have only had components of the Delcath system manufactured for us in small quantities for use in pre-clinical studies and clinical trials. We will require greater quantities for the Phase III clinical trials and significantly greater quantities to commercialize the product. If we are unable to obtain adequate supplies of components from our existing suppliers, or need to switch to an alternate supplier, the completion of our clinical trials and commercialization of the Delcath system could be delayed. If we are unable to successfully develop and commercialize the Delcath system, we will not generate significant revenues. The Delcath system for the administration of chemotherapy agents to a liver isolated by the system is the only product we are seeking to commercialize in the foreseeable future. Accordingly, our future financial performance will depend upon the successful and timely completion of clinical trials, commercial introduction and consumer acceptance of the Delcath system. If we do not successfully commercialize this system we will not generate significant revenues and our business will cease. We do not expect to begin the commercial sale of the Delcath system for at least 24 months, if ever. We may not be successful in commercializing the Delcath system because we lack sales, marketing and distribution experience and will be dependent upon third parties to market the Delcath system in foreign markets. We have not previously sold, marketed or distributed any products and currently do not have the personnel, resources, experience or other capabilities to adequately market the Delcath system. We intend to directly market and sell the Delcath system in the United States through a direct sales force. As a result, our success will depend upon our ability to attract and retain skilled sales and marketing personnel. Competition for such personnel is intense, and we cannot assure you that we will be successful in attracting or retaining such personnel. Our inability to attract and retain skilled sales and marketing personnel could materially adversely affect our business, financial condition and results of operations. If we enter foreign markets, we intend to do so through marketing agreements with third parties. Any revenues we receive from the sale of the Delcath system in foreign markets will depend upon the efforts of these parties and may be less than we would otherwise receive if we marketed the product through our own sales force. We cannot assure you that we will be able to establish in-house marketing, sales and distribution capabilities or relationships with third parties to effectively fulfill these functions in foreign markets. Our failure to establish marketing capabilities or to enter into marketing arrangements with third parties would have a material adverse effect on our business, financial condition and results of operations. There may be low demand for the Delcath system. The Delcath system may not gain significant market acceptance among physicians, patients and healthcare payors. Market acceptance of the Delcath system will depend upon: o the ability of our clinical trials to demonstrate a significant reduction in the mortality rate for the kinds of cancers treated at a cost effective price; o our ability to educate physicians on the use of the system and its benefits compared to other treatment alternatives; and 9

o our ability to convince healthcare payors that use of the Delcath system results in reduced treatment costs of patients. This will require substantial efforts and expenditures. We only have limited experience in these areas and we cannot assure you that we will be successful in achieving these goals. Moreover, the Delcath system replaces treatment methods in which many hospitals have made a significant investment. Hospitals may be unwilling to replace their existing technology in light of their investment and experience with competing technologies. Many doctors and hospitals are reluctant to use a new medical technology until its value has been demonstrated. The lack of acceptance of the Delcath system by the healthcare market would have a material adverse effect on our business, financial condition and results of operations. The Delcath system may be rendered obsolete and noncompetitive by technological change. Technological developments are expected to continue at a rapid pace in both industry and academia which could result in a short product life cycle for our Delcath system. The healthcare industry is characterized by extensive research efforts, rapid technological progress and intense competition from numerous organizations, including biotechnology firms and academic institutions. There is continuous research in the medical community on different ways to treat or prevent cancer. Specifically, many large pharmaceutical companies and research institutions are developing systems and devices to improve the outcome of chemotherapy treatment for cancer. Some are developing chemotherapy agents with reduced toxicity, which may make them more desirable treatment alternatives than doxorubicin. Some pharmaceutical companies are also developing products to reduce the toxicity and side effects of chemotherapy treatment. In addition, gene therapy, vaccines, use of radio frequency waves and other minimally invasive procedures are currently being developed as alternatives to chemotherapy. We may not be able to compete in the market for liver cancer treatments because of the numerous treatment alternatives and the strength of our competitors. The Delcath system competes with all forms of liver cancer treatments which are alternatives to resection, or surgical removal, of the tumor, including intravenous chemotherapy treatment, radiation, targeted chemotherapy delivery through implanted infusion pumps and radio frequency waves. Many of our competitors have substantially greater financial, technological, research and development, marketing and personnel resources. In addition, some of our competitors have considerable experience in conducting clinical trials and other regulatory approval procedures. As a result, our competitors may develop more efficacious or more affordable products or treatment methods, or achieve earlier product development, patent protection, regulatory approval or product commercialization than we do. Other risks relating to business. We rely heavily on our key personnel. Our success will depend largely on the continuing efforts of Samuel Herschkowitz, our Chief Technical Officer, M.S. Koly, our Chief Executive Officer and other key personnel. Our business may be adversely affected if the services of our key personnel become unavailable to us. While we have obtained a key-man life insurance policy on the life of each of Dr. Herschkowitz and Mr. Koly in the amount of $2,000,000, this amount may not be sufficient to offset the loss of their services. We may be unable to successfully manage our business when, if ever, we commence the commercial sale of the Delcath system. To date, we have been engaged in research and development activities. When, if ever, we commence the commercial sale of the Delcath system, our internal information systems, procedures and controls may not be adequate to support our operations. Commercial sale of the system will also impose significant added responsibilities on our senior management, and we cannot assure you that they will successfully manage such added responsibilities. In addition, we may need to recruit and integrate into our management structure additional senior level managers and executives and we may not be successful at doing so. 10

Because of our limited resources we may be unable to enforce our intellectual property rights. Our success depends significantly on our ability to protect our proprietary rights to the technologies used in our product, and we may be unable to do so. If a third party violates our intellectual property rights, we may be unable to enforce our rights because of our limited resources. Third parties may copy or obtain and use our proprietary technologies, ideas, know-how and other proprietary information without authorization, design around our existing patents or independently develop technologies similar or superior to our technologies. In addition, the confidentiality and non-competition agreements between us and our key employees, distributors, consultants, labs, institutions, researchers conducting trials and manufacturers may not provide meaningful protection of our proprietary technologies or other intellectual property if unauthorized use or disclosure occurs. We may be found to infringe on patents issued to others or need to acquire licenses under patents belonging to others. Our commercial success will depend, in part, on our ability to avoid infringing patents issued to others. If we are determined to be infringing on any third party patents, we could be required to pay substantial damages, alter our products or processes, obtain licenses under patents belonging to others or curtail our activities. We may not be able to obtain required licenses or alter our products or processes on acceptable terms or at all. The medical device industry is characterized by a substantial amount of litigation over patent and other intellectual property rights. Determining whether a product infringes a patent involves complex legal and factual issues, and the outcome of patent litigation actions is often uncertain. We are uninsured against product liability claims and may be unable to obtain insurance coverage. Clinical trials, manufacturing, marketing and product sales may expose us to liability claims from the use of the Delcath system. Though participants in clinical trials are generally required to execute consents and waivers of liability they may still be able to assert product liability claims against us. Claims for damages, whether or not successful, could cause delays in the clinical trials and result in the loss of physician endorsement. We do not currently carry product liability insurance and we may not be able to acquire product liability insurance at sufficient coverage levels or at an acceptable cost. If we are unable to obtain sufficient insurance coverage at an acceptable cost, we may not be able to commercialize the Delcath system. A successful product liability claim or recall would have a material adverse effect on our business, financial condition and results of operations. Risks related to this offering, our share price and corporate control The offering price of our common stock was arbitrarily determined and, therefore, may not be indicative of their value. The initial public offering price of our common stock has been arbitrarily determined by negotiation between us and the underwriter and is not necessarily related to our assets, book value or potential earnings or any other recognized criteria of value. Additionally, the initial public offering price of our common stock may not be indicative of the prices that may prevail in the public market. Your investment will be subject to immediate and substantial dilution. Following this offering the net tangible book value of a share of common stock will be $1.89 and you will have paid $6.00 per share. As a result, you will experience immediate and substantial dilution of $4.11 per share, or 68.5%, between the net tangible book value per share of common stock after this offering and the initial public offering price per share. This dilution is due to the fact that our earlier investors paid less than the initial public offering price when they purchased their shares of common stock and because we have incurred losses since our inception. A public market for our shares of common stock may not develop or be sustained. Before this offering, there has been no public trading market for our shares of common stock. We cannot assure you that a regular trading market for our common stock will develop after this offering or that, if 11

developed, it will be sustained. We will apply to list our shares on the Nasdaq SmallCap Market. Although we believe we meet the initial listing criteria, we cannot assure you that in the future we will be able to meet the criteria for continued listing. If, in the future, our shares of common stock are not listed on Nasdaq and the trading price of our shares of common stock was to fall below $5.00 per share, trading in our common stock would become subject to the Securities and Exchange Commission's penny stock rules, which could severely limit the market liquidity of our shares of common stock and the ability of purchasers in this offering to sell their shares of common stock in the secondary market. The number of shares eligible for future sale and the existence of registration rights could depress the market for shares of our common stock. Sales of a substantial number of our shares of common stock in the public market, or the perception that these sales may occur, could adversely affect the market price of our common stock. This could also impair our ability to raise additional capital through the sale of our equity securities. After this offering, we will have approximately 5,418,732 shares of common stock outstanding or approximately 5,718,732 shares if the underwriter exercises its over-allotment option in full. The shares sold in this offering will be freely tradable. All of the remaining shares are restricted securities as that term is defined under Rule 144. However, approximately 2,010,574 of these will be immediately eligible for sale and 138,952 shares will become eligible for sale in the public market 90 days after the date of this prospectus, subject to the contractual limitations described in "Shares Eligible for Future Sale." We have granted registration rights to the underwriter for the shares of common stock issuable upon exercise of the underwriter's warrants. These registration rights are discussed in the "Description of Securities" and "Shares Eligible for Future Sale" sections of this prospectus. We cannot predict the effect, if any, that sales of these additional securities or the availability of these additional securities for sale will have on the market prices prevailing from time to time. After this offering we will continue to be controlled by existing stockholders. Upon completion of this offering, the officers, directors and principal stockholders listed under "Principal Stockholders" will beneficially own approximately 39.2% of our outstanding common stock, and 37.3% if the underwriter's over-allotment option is exercised in full. Consequently, such persons, as a group, will be able to control the outcome of all matters submitted for stockholder action, including the election of members to our board of directors and the approval of significant change-in-control transactions. Therefore, they will effectively control our management and affairs. This may have the effect of delaying or preventing a change in control. Our charter documents contain provisions which may discourage takeover attempts. Our restated certificate of incorporation divides the board of directors into three classes. Approximately one third of the members of the board of directors are elected at each annual meeting of stockholders. This may have the effect of delaying, deferring, or discouraging changes in control of Delcath. In addition, our board of directors has the authority, after the offering, to issue up to 10,000,000 shares of preferred stock and to determine the price, rights, preferences, privileges and restrictions, including voting and conversion rights of those shares, without any further vote or action by our common stockholders, except as may be required by law or applicable rules of Nasdaq. The issuance of preferred stock could have the effect of making it more difficult for a third party to acquire a majority of our outstanding voting stock. 12

USE OF PROCEEDS The net proceeds to Delcath from the sale of shares being offered by this prospectus, after deducting the underwriting discount and estimated expenses of this offering, are estimated to be $10,000,000. We expect to use these net proceeds approximately as follows: Approximate Approximate Percentage Application of Net Proceeds Dollar Amount of Net Proceeds - --------------------------- --------------- ---------------- Research and development: Phase III clinical trials using the Delcath system with doxorubicin ..... $ 6,500,000 65.0% Research and development stage clinical trials for other chemotherapy Agents ................................................................ 600,000 6.0 Reduce the cost of the Delcath filtration system ........................ 400,000 4.0 Introduce the Delcath system into foreign markets ........................ 500,000 5.0 Working capital and general corporate purposes ........................... 2,000,000 20.0 ------------ ----- Total ................................................................ $ 10,000,000 100.0% ============ ===== Phase III clinical trials using the Delcath system with doxorubicin. These costs represent: o The costs of (i) recruiting medical centers to conduct the trials and patients to participate in the trials and (ii) treating patients, including the costs of the Delcath system and payments for unreimbursed medical expenses for patients receiving treatment with the system. We estimate that the average costs to treat a patient will be under $20,000, and we expect to treat up to 274 patients. o Approximately $950,000 for the fees and expenses of the clinical research organization which we anticipate hiring to conduct the trials, collect and process the data and prepare and file a pre-market approval application and approximately $550,000 for associated overhead, including the costs of additional personnel and consultants. Research and development stage clinical trials for other chemotherapy agents. This amount represents the costs of conducting research and development stage clinical trials for the use of other chemotherapy agents with the Delcath system for the treatment of liver cancer. These costs represent the costs of non-animal testing, animal testing, testing with humans, monitoring the testing and collecting and processing data. Additional financing will be required to conduct Phase II and III clinical trials. Reduce the cost of the Delcath filtration system. This amount represents the costs to design, develop and test a filter which will cost less than the third-party filter currently used in the Delcath system and include the salaries of an engineer and technician. Introduce the Delcath system into foreign markets. These costs represent the salaries of five employees to be hired, travel and promotional material to establish alliances with leading hospitals in countries being targeted and enlist their support in obtaining regulatory approval in their territories and to establish strategic partnerships with domestic and/or foreign marketing firms. Working capital and general corporate purposes. These costs include general and administrative costs, including the salaries of our executive officers. Pending the above uses, the net proceeds of this offering will be invested in short-term, interest-bearing, investment-grade securities. Over-allotment option. If the underwriter exercises the over-allotment option in full, we will realize additional net proceeds of $1,566,000, which will be added to working capital purposes. 14

The above allocation represents our best estimate of the allocation of the net proceeds of this offering based upon the current status of our business. We based this estimate on assumptions, including that the Delcath system will have obtained FDA marketing approval within 24 months from the closing of this offering. If any of these factors change, we may find it necessary to reallocate a portion of the proceeds within the above described categories or use portions of the proceeds for other purposes. Our estimates may prove to be inaccurate, new programs or activities may be undertaken which will require considerable additional expenditures or unforeseen expenses may occur. Based upon our current plans and assumptions relating to our business plan, we anticipate that the net proceeds of this offering will satisfy our capital requirements for at least 12 months following the closing of this offering. If our plans change or our assumptions prove to be inaccurate, we may need to seek additional financing sooner than currently anticipated or curtail our operations. We cannot assure you that the proceeds of this offering will be sufficient to fund our clinical trials with respect to the use of the Delcath system with doxorubicin to treat liver cancer. We also cannot assure you that additional financing will become available if needed. We will invest proceeds not immediately required for the purposes described above principally in United States government securities, short-term certificates of deposit, money market funds or other short-term interest-bearing investments. 15

DILUTION The difference between the initial public offering price per share and the net tangible book value per share of common stock after this offering constitutes the dilution to investors in this offering. Net tangible book value per share is determined by dividing total tangible assets less total liabilities by the number of outstanding shares of common stock. At March 31, 2000, we had a net tangible book value of $225,246 or $.21 per share. At March 31, 2000, our net tangible book value would have been $242,348 or $.07 per share after giving pro forma effect to: o the conversion of all outstanding shares of our convertible preferred stock into 1,056,192 shares of common stock; o the payment of $1,454,170 of estimated accumulated dividends assuming this offering closes on June 30, 2000 through the issuance of 851,781 shares of common stock and the payment of $484,723 of estimated accumulated dividends in cash; o the issuance in April 2000 of 292,426 shares to existing stockholders for $501,825; and o the issuance of 125,000 shares to Morse, Zelnick, Rose and Lander LLP for legal services, at the date of this prospectus. After also giving effect to the sale of the 2,000,000 shares being offered at an initial public offering price of $6.00 per share and after deducting estimated underwriting discounts and expenses of this offering, our adjusted net tangible book value at March 31, 2000 would have been $10,242,348 or $1.89 per share, representing an immediate increase in net tangible book value of $1.82 per share to the existing stockholders and an immediate dilution of $4.11 or 68.5% per share to new investors. The following table illustrates the above information with respect to dilution to new investors on a per share basis: Initial public offering price ................................................ $ 6.00 Pro forma net tangible book value at March 31, 2000 ......................... $ .07 Increase in pro forma net tangible book value attributable to new investors.. 1.82 ------ Adjusted pro forma net tangible book value after offering .................... 1.89 ------- Dilution to new investors .................................................... $ 4.11 ======= The following table sets forth, on a pro forma basis as of March 31, 2000, with respect to our existing stockholders and new investors, a comparison of the number of shares of common stock we issued, the percentage ownership of those shares, the total consideration paid, the percentage of total consideration paid and the average price per share. Shares Purchased Total Consideration Average ----------------------- -------------------------- Price Per Number Percent Amount Percent Share ----------- --------- -------------- --------- ---------- Existing stockholders ......... 3,418,732 63.1% $10,566,686 46.8% $ 3.09 New investors ................. 2,000,000 36.9 12,000,000 53.2 6.00 --------- ----- ----------- ----- Total ...................... 5,418,732 100.0% $22,566,686 100.0% ========= ===== =========== ===== The above table assumes no exercise of the underwriter's over-allotment option. If the underwriter exercises the over-allotment option in full, we estimate that the new investors will have paid $13,800,000 for the 2,300,000 shares of common stock being offered, representing approximately 56.6% of the total consideration for 40.2% of the total number of shares of common stock outstanding. In addition, the above table does not give effect to the shares issuable upon exercise of outstanding options and warrants. To the extent that any of these options or warrants are exercised, there will be further dilution to the new investors. 16

DIVIDEND POLICY We have never declared or paid any dividends to the holders of our common stock and we do not expect to pay cash dividends in the foreseeable future. We currently intend to retain all earnings for use in connection with the expansion of our business and for general corporate purposes. Our board of directors will have the sole discretion in determining whether to declare and pay dividends in the future. The declaration of dividends will depend on our profitability, financial condition, cash requirements, future prospects and other factors deemed relevant by our board of directors. Our ability to pay cash dividends in the future could be limited or prohibited by regulatory requirements and the terms of financing agreements that we may enter into or by the terms of any preferred stock that we may authorize and issue. CAPITALIZATION The following table sets forth our capitalization as of March 31, 2000: o on an actual basis; o on a pro forma basis to reflect: o the issuance of 1,056,192 shares upon conversion of all of our preferred stock; o the issuance of 851,781 shares as payment of $969,447 of estimated accumulated dividends on our preferred stock as of the date of this prospectus, assuming the offering closes on June 30, 2000; o the payment of $484,723 for the remaining accumulated dividends on our preferred stock as of the date of this prospectus, assuming the offering closes on June 30, 2000; o the issuance of 292,426 shares to existing stockholders in April 2000 for proceeds of $501,825; and o the issuance of 125,000 shares to Morse, Zelnick, Rose and Lander LLP for legal services, at the date of this prospectus; and o on an as adjusted basis to give effect to the pro forma adjustments and to the sale of shares, at an assumed initial public offering price of $6.00 per share, after deducting the underwriting discounts and estimated offering expenses payable by us. The following table excludes from the common stock outstanding 602,736 shares of common stock reserved for issuance upon exercise of outstanding options and warrants.

SELECTED FINANCIAL DATA The selected financial data set forth below should be read in conjunction with Management's "Plan of Operation" included elsewhere in this prospectus. The operating data for each of the years in the two-year period ended December 31, 1999 and for the period from inception through December 31, 1999, and the balance sheet data at December 31, 1999, are derived from our financial statements which have been audited by KPMG LLP, independent accountants, and are included in this prospectus. The operating data for the three month periods ended March 31, 1999 and 2000 and for the period from inception through March 31, 2000 and the balance sheet data as at March 31, 2000 are derived from our unaudited financial statements. The unaudited financial statements have been prepared on substantially the same basis as the audited financial statements and, in the opinion of management, include all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the results of operations for these periods. Historical results are not necessarily indicative of the results to be expected in the future, and the results of interim periods are not necessarily indicative of results for the entire year.

PLAN OF OPERATION Background We were founded in 1988 by a team of physicians. Since our inception, we have been a development stage company engaged primarily in developing and testing the Delcath system for the treatment of liver cancer. A substantial portion of our historical expenses have been in support of the development and the clinical trials of our product. To date, we have been dependent upon venture capital financing to fund our activities. Without an FDA approved product, we have generated minimal revenues from product sales. We have been unprofitable to date and have had losses of $2,049,980 and $572,581 for the years ended December 31, 1998 and 1999 and $210,124 for the three months ended March 31, 2000. Cumulative losses from inception through March 31, 2000 were $11,522,086. We expect to incur additional losses over the next three years and anticipate these losses will increase significantly in this period due to continued requirements for product development, clinical studies, regulatory activities, manufacturing and establishment of a sales and marketing organization. The amount of future net losses and time required to reach profitability are uncertain. Our ability to generate significant revenue and become profitable will depend on our success in commercializing our device. We incurred non-cash compensation expense in connection with the grants of options to purchase common stock to founders, employees, and directors because those options had a weighted average exercise price below the fair value of the common stock at the dates of the grants. This compensation expense from inception (August 5, 1988) through December 31, 1999 totaled $2,520,170. Liquidity and Capital Resources We have financed our operations to date primarily through private placements of our common and preferred stock. Through March 31, 2000, we raised $9,314,861 through the sale of our class A preferred stock, class B preferred stock and common stock. Cash used to fund operations from inception through March 31, 2000 was $8,922,256. Our cash and cash equivalents totaled $218,255 at March 31, 2000, a decrease of $342,823 from December 31, 1999. Since January 1, 1998, our principal source of cash has been the following financing transactions: o In January 1998, we sold 43,704 shares of common stock at a price of $11.44 per share to Johnson & Johnson Development Corporation, and received proceeds of $500,000. o In April 1998, we issued 10,926 shares of common stock upon exercise of options at a price of $6.18 per share for proceeds of $67,500. o In September 1998, we sold 4,370 shares of common stock to an individual at a price of $13.04 per share and received proceeds of $57,000. o In April 1999, we issued 2,913 shares of common stock upon exercise of warrants at a price of $8.58 per share, and received proceeds of $24,998. o In July 1999, we sold 59,514 shares of common stock at a price of $13.04 per share and received proceeds of $776,192. o In April 2000, we sold 292,426 shares of common stock at a price of $1.72 per share, as part of a rights offering to our existing stockholders and option holders, and received proceeds of $501,825. We expect to continue to incur expenses related to the research and development of our technology, including pre-clinical and clinical trials, and the development of additional products. We expect to incur significant additional operating losses over each of the next several years and expect cumulative losses to increase significantly as we continue to expand our research and development, clinical trials and marketing efforts. During the next 12 months, we expect to purchase approximately $150,000 in computer, laboratory and testing equipment, primarily for testing of a lower cost filter. We also expect to hire additional employees in the areas of research and development, regulatory and clinical management, marketing and administrative functions at an estimated annual expense of $600,000. The number and timing of such hiring will vary depending upon the success of the international marketing efforts and progress of the clinical trials. 19

Immediately prior to the closing of this offering, all of our preferred stock will convert into shares of common stock. As part of this conversion, the preferred stockholders will receive an estimated 851,781 shares of common stock and $484,723 in cash in payment of accumulated dividends, assuming the offering closes on June 30, 2000. We believe that existing cash and cash equivalents, together with net proceeds of approximately $10,000,000 from this offering, will be sufficient to finance our operations for at least twelve months from the date of this prospectus. Our future liquidity and capital requirements, however, will depend on numerous factors, including (a) the progress of our research and product development programs, including clinical studies, (b) the timing and costs of various United States and foreign regulatory filings, (c) the timing and effectiveness of product commercialization activities, including marketing arrangements overseas, (d) the timing and costs involved in obtaining regulatory approvals, if ever, and complying with regulatory requirements, (e) the timing and costs involved in preparing, filing, prosecuting, defending and enforcing intellectual property rights and (f) the effect of competing technological and market developments. If the proceeds of this offering, together with our currently available funds, are not sufficient to satisfy our spending plans, we will be required to revise our capital requirements or to seek additional funding through borrowings and/or additional sales of securities. We cannot assure you that the proceeds of this offering will be sufficient to fund our clinical trials with respect to the use of the Delcath system with doxorubicin to treat liver cancer. We also cannot assure you that additional financing will become available if needed. 20

BUSINESS Overview Delcath has developed a system to isolate the liver from the general circulatory system and to administer chemotherapy and other therapeutic agents directly to the liver. Using the Delcath system, blood flowing into the liver, after being infused with chemotherapy agents, is redirected out of the patient's body, passed through filters which remove most of the chemotherapy agents and then returned to the patient's general circulatory system. Isolating the liver and cleansing the blood before its return into the patient's circulatory system protects other parts of the body from the harmful side-effects of chemotherapy. We believe that the use of the Delcath system in treatment of liver cancer will allow higher dosages of chemotherapy to be administered to the liver than can be administered with conventional intravenous delivery. The Delcath system is not currently approved for marketing by the United States Food and Drug Administration, and it cannot be marketed in the United States without FDA approval. With the proceeds of this offering, we plan to conduct Phase III clinical trials designed to secure marketing approval for the system in the United States and possibly in foreign markets. Strategy Our objective is to establish the use of the Delcath system as the standard technique for delivering chemotherapy agents to the liver and to expand the Delcath technology so that it may be used in the treatment of other liver diseases and of cancers in other parts of the body. Our strategy includes the following: o Complete clinical trials to obtain FDA approval for use of the Delcath system with doxorubicin to treat primary liver cancer and malignant melanoma that has spread to the liver. Our highest priority is completing the Phase III clinical trials, data preparation, statistical analysis and regulatory documents associated with an application for pre-market approval of commercial sale of the Delcath system in the United States. FDA approval of our application will permit us to market the Delcath system to administer doxorubicin in the treatment of primary liver cancer and melanoma that has spread to the liver. o Obtain approval to market the Delcath system in the United States for the treatment of other forms of liver cancer and hepatitis using other chemotherapy agents and treatment of hepatitis using anti-viral drugs. In addition to researching the use of other chemotherapeutic agents with the Delcath system to treat cancer, we plan to research the use of other compounds with the Delcath system to treat other diseases, such as hepatitis. Our timing to begin these studies will depend on our ability to establish strategic alliances with pharmaceutical manufacturers or other strategic partners in conjunction with our research into other therapeutic compounds or raise additional funds for these purposes. FDA approval will be required to market the Delcath system for these uses. o Introducing the Delcath system into foreign markets. We will seek to establish strategic relationships with domestic and foreign firms that have recognized presence or experience in foreign markets that we intend to target. Our strategy is to focus on markets that have a high incidence of liver cancer and the means to provide and pay for cancer treatments. According to the World Health Organization, many Asian and European countries, including China, Japan, Hong Kong, the Philippines, France, Germany, Italy and Spain have a higher incidence of liver cancer than the United States. We intend to seek to enter into arrangements with strategic partners who have experience with obtaining regulatory approval or marketing medical devices in those markets. o Reduce the cost of the Delcath system's filtration system. The filters we currently use to detoxify blood outside the body comprise a significant portion of the cost of the Delcath system kit. We are researching technologies which may enable filters to be produced at a lower cost. o Leverage our core double balloon catheter technology to expand our product offerings to include systems for administering chemotherapy agents in other parts of the body. Early studies have indicated that the same principles employed in liver isolation may be applied to other organs. By 21

modifying the catheter, including the spacing, size and number of the balloons, the Delcath system initially may be adapted for use in treatment of cancers in other areas of the body, including the limbs, kidneys, lungs, and other organs of the abdominal cavity. Future studies may investigate the use of the Delcath system in other organs as well. We have not yet begun to conduct this research and do not intend to do so until we obtain additional financing or enter strategic relationships. The Cancer Treatment Market The American Cancer Society projects that about 1,200,000 Americans will be diagnosed with cancer in 2000. According to the American Cancer Society's "Cancer Facts and Figures -- 2000", cancer remains the second leading cause of death in the United States. While researchers continue to develop innovative new treatments for some forms of this disease, surgical resection, chemotherapy, radiation and hormone therapy continue to be the most commonly used treatments. The financial burden of cancer is great for patients, their families and society. The National Cancer Institute, in the American Cancer Society's "Facts and Figures," estimates the overall costs of cancer to be $107 billion, including $37 billion in direct medical costs, $11 billion for indirect morbidity costs (cost of lost productivity due to illness) and $59 billion for indirect mortality costs (cost of lost productivity due to death). The Liver Cancer Market Liver cancer is one of the most prevalent and lethal forms of cancer throughout the world. There are two forms of liver cancer: primary and metastatic. Primary liver cancer originates in the liver. Secondary, or metastatic, liver cancer results from the spread of cancer from other places in the body to the liver. In the liver, primary tumors can be removed only when they are located in one of the liver's two lobes, which occurs in less than 20% of the cases of primary liver cancer. A significant number of patients treated for primary and metastatic liver cancer will experience a recurrence of their disease. Metastatic liver cancer is characterized by microscopic pieces of other forms of cancer that detach from the primary site and travel via the blood stream and lymphatic system into the liver, where they grow into new tumors. This growth often continues even after removal of the primary cancer or cancerous organ. When cancer cells enter the liver and develop into tumors, they tend to grow very quickly. In many cases, the patient dies not from the primary cancer, but from the tumors in the liver; the liver becomes the "life limiting organ." People cannot survive without a liver capable of performing its critical biologic functions: facilitating the conversion of food into energy and filtering toxic agents from the blood. The liver is one of the three most common sites to which cancer may spread. Due to numerous factors, including the absence of viable treatment options, metastatic liver cancer often causes death. According to a recent report, liver cancer is the third most common form of cancer worldwide. The worldwide incidence of primary liver cancer is estimated to be 1,000,000 new patients each year and there are an estimated 1,250,000 deaths worldwide caused by all forms of liver cancer. The American Cancer Society estimates that the incidence of primary liver cancer in the United States in 2000 is approximately 15,300 new cases and that primary liver cancer causes 13,000 deaths each year. According to a 1999 article in the New England Journal of Medicine, researchers reported that annual new diagnoses of liver cancer increased from 1.4 cases per 100,000 persons in the late 1970s to 2.4 cases per 100,000 persons in the 1990s. Liver cancer is among the most virulent forms of cancer. Approximately 94% of patients diagnosed with primary liver cancer will die within five years and approximately 75% will die within one year from diagnosis. Primary liver cancer is particularly prevalent in Southern Europe, Asia and developing countries, where the primary risk factors for the disease are present. These risk factors include: hepatitis-B, hepatitis-C, relatively high levels of alcohol consumption, aflatoxin, cigarette smoking and exposure to industrial pollutants. Our current product is designed to treat primary liver cancer and melanoma which has spread to the liver. 22

Liver Cancer Treatments The prognosis for primary and secondary liver cancers is poor. Although limited treatment options are currently available for liver cancer, they are typically ineffective, are generally associated with significant side effects and can even cause death. Traditional treatment options include surgery, chemotherapy, cryosurgery, percutaneous ethanol injection and radiation. Surgery While surgery is considered the "gold standard" treatment option to address liver tumors, more than 80% of liver cancer patients are unresectable, which means they do not qualify for surgical removal. This is most often due to the following: o Operative risk: limited liver function or poor patient heath threatens survival as a result of the surgery; or o Technical feasibility: the proximity of a cancerous tumor to a critical organ or artery, or the size, location on the liver or number of tumors makes surgery not feasible. For the few patients who qualify for surgery, there are significant complications related to the procedure and the operative mortality rate is 2%. Recurrence of tumors is common and in that event, surgery typically cannot be repeated. We believe that delivery of drugs with the Delcath system may enable surgical resection in some of the cases which are currently inoperable by reducing the size and number of tumors sufficiently to make resection feasible. Shrinking a tumor using chemotherapy and then removing the tumor is a procedure known as adjuvant therapy. After resection, chemotherapy can be administered through the Delcath system with the objective of destroying micrometastases in the liver that may remain undetected, thus preventing or delaying any recurrence of tumor growth. Chemotherapy The most prevalent form of liver cancer treatment is intravenous chemotherapy. The effectiveness of this treatment, however, is limited by its side effects. Generally, the higher the dosage of chemotherapy administered, the greater its ability to kill cancer cells. However, due to the toxic nature of chemotherapy agents, the higher the dosage administered, the greater damage chemotherapy agents cause to healthy tissues. As a result, the dosage of chemotherapy required to kill cancer cells can be lethal to patients. The side effects caused by doxorubicin, the drug we are seeking to have approved for use in the Delcath system, is representative of the side effects associated with many chemotherapy agents. Doxorubicin causes irreversible heart tissue damage. Depending on dosage levels, the damage caused by doxorubicin can be serious and lead to congestive heart failure. Doxorubicin can also cause severe mucositis leading to ulceration of the mouth and digestive organs, damage to a patient's immune system through destruction of bone marrow cells, as well as acute nausea, severe vomiting, dermatological problems and hair loss. The use of doxorubicin can be fatal even when it is administered with careful patient monitoring. The limited effectiveness of intravenous chemotherapy treatment and its debilitating, often life-threatening side effects makes the decision to undergo chemotherapy treatment difficult. In some instances, in an attempt to shrink tumors, a physician may prescribe a radically high-dose of chemotherapy, despite its side effects. In other cases, recognizing the inevitable result of liver cancer, the physician and patient choose only to manage the patient's discomfort from cancer with pain killers while foregoing treatment. To address this trade-off between the efficacy of intravenous chemotherapy treatment and its dire side effects, physicians have experimented with techniques to isolate the liver from the general circulatory system and to achieve a targeted delivery of chemotherapy agents to the liver. In the 1980s, a physician developed a procedure in which he surgically diverted the blood flow from the liver while infusing high dosages of chemotherapy agents into the liver. A filtration circuit reduced drug concentrations before returning the diverted blood to the patient. The treatment, however, was not embraced by the medical community because it 23

is highly invasive, resulting in prolonged recovery times, long hospital stays and excessive costs. Other physicians have experimented with the delivery of chemotherapy agents to the liver by catheter, attempting to use one or more catheters to remove chemotherapy agents before they enter the general circulatory system. We are unaware of any system, however, which contains the patented attributes of the Delcath design. Cryosurgery Cryosurgery is the destruction of cancer cells using sub-zero temperatures in an open surgical procedure. During cryosurgery, multiple stainless steel probes are placed into the center of the tumor and liquid nitrogen is circulated through the end of the device, creating an iceball. Cryosurgery involves a cycle of treatments in which the tumor is frozen, allowed to thaw and then refrozen. While cryosurgery is considered to be relatively effective, we believe adoption of this procedure has been limited because: o It is not an option for patients who cannot tolerate an open surgical procedure; o It involves significant complications which are similar to other open surgical procedures, as well as liver fracture and hemorrhaging caused by the cycle of freezing and thawing; o It is associated with mortality rates estimated to be between one and five percent; and o It is expensive compared to other alternatives. Percutaneous Ethanol Injection Percutaneous ethanol injection, or PEI, involves the injection of alcohol into the center of the tumor. The alcohol causes cells to dry out and cellular proteins to disintegrate, ultimately leading to tumor cell death. While PEI can be successful in treating some patients with primary liver cancer, it is generally considered ineffective on large tumors as well as metastatic tumors. Patients are required to receive multiple treatments, making this option unattractive for many patients. Complications include pain and alcohol introduction to bile ducts and major blood vessels. In addition, this procedure can cause cancer cells to be deposited along the needle tract when the needle is withdrawn. Radiation Therapy Radiation therapy uses high dose x-rays to kill cancer cells. Radiation therapy is not considered an effective means of treating liver cancer and is rarely used for this purpose. Radiation is often used as an adjunct to other cancer treatments. Implanted Infusion Pumps Implanted Infusion Pumps can be used to better target the delivery of chemotherapy agents to the tumor. Pfizer's "Infusaid" is an implantable pump typically used to treat colorectal cancer which has metastasized to the liver. Infusaid, however, lacks a means of preventing the entry of chemotherapy agents into the patient's general circulation after it passes through the liver. This technique does not enable physicians to prescribe higher doses of chemotherapy. Other Methods of Treatment Still other liver cancer treatments include: liver transplants, embolization, tumor ablation through the use of radio frequency waves and the use of biological response modulators, monoclonal antibodies and liposomes. The effectiveness of these treatments is limited, many have dose limiting side effects, and none is widely used. 24

The Delcath System The Delcath system is designed to address the critical shortcomings of conventional intravenous chemotherapy delivery. The Delcath system isolates the liver from the general circulatory system during liver cancer treatments with chemotherapy and then returns the blood exiting the liver to the general circulatory system only after the chemotherapy agent has been substantially removed by filtration outside the body. We believe that the Delcath system allows higher chemotherapy doses to be administered to the liver than can be administered by conventional intravenous delivery. By filtering out a substantial portion of the chemotherapy agent before the blood is returned to the blood stream, the heart and other organs of the body are protected from the harmful side-effects of chemotherapy. The Delcath system kit includes the following disposable components: o Infusion Catheter -- a thin-walled arterial infusion catheter used to deliver chemotherapy to the liver; o Double Balloon Catheter -- a multi-passageway catheter used to isolate and divert the drug-laden blood exiting the liver; o Extracorporeal Filtration Circuit -- a blood tubing circuit incorporating the disposable components used with a blood pump to push the isolated blood through the system's filters and guide the cleansed blood back to the patient; o Filters -- activated carbon blood filters used to remove most of the chemotherapy agent from the isolated blood after it has flowed through the liver and before it returns to the patient's general circulation; and o Return Catheter -- a thin-walled blood sheath used to deliver the filtered blood from the extracorporeal filtration circuit back into one of the major veins returning blood to the right atrium of the heart. The double balloon catheter has one large passageway and three smaller passageways. Each of two low-pressure balloons is inflated through one of the three smaller passageways. Blood flows out of the liver through the large passageway to the filtration system. A separate access port attaches to the large passageway and is designed for sampling fluid or flushing the system. The third smaller passageway allows blood exiting the legs and kidneys to bypass the liver and return to the heart. The Delcath procedure involves a series of three catheter insertions, each of which is made through the skin. During test procedures, patients are treated with intravenous sedation and local anesthesia at catheter insertion sites. In some cases general anesthesia has been used. An infusion catheter is inserted into the artery through which blood normally flows to the liver. A second catheter -- the Delcath double balloon catheter -- is inserted through the inferior vena cava. The balloons on the double balloon catheter are then inflated. This procedure prevents the normal flow of blood from the liver to the heart through the inferior vena cava because the inferior vena cava has been blocked. A chemotherapy agent is then infused into the liver through the infusion catheter. The infused blood is prevented from flowing to the heart, but exits the liver through perforations on the double balloon catheter and flows through this catheter out of the body where the infused blood is pumped through activated charcoal filters to remove most of the chemotherapy agent. The filtered blood is returned to the patient through the jugular vein which leads to the superior vena cava and the heart, thus restoring the cleansed blood to normal circulation. Infusion is administered over a period of 30 minutes. Filtration occurs during infusion and for 30 minutes afterward. The catheters are removed and manual pressure is maintained on the catheter puncture sites for approximately 15 minutes. The entire procedure takes approximately two to three hours to administer. During Phase I and II clinical trials, patients remained in the hospital overnight for observation after undergoing treatment with the Delcath system. Once physicians become familiar with using the Delcath system, we expect the procedure to be performed on an outpatient basis, with the patient resuming normal activities the day after the procedure is performed. We expect a patient to undergo an average of four treatments, one every three weeks. A new Delcath system kit is used for each treatment. Integral to our research and development efforts is our program of clinical research with prominent researchers and physicians conducted at Yale University, M.D. Anderson Cancer Center, and the Robert Wood Johnson Medical School/Cancer Institute of New Jersey. 25

Our Phase III Clinical Trials Phase III human clinical trials are a prerequisite for FDA approval of Delcath's pre-marketing application. During these trials, administration of doxorubicin through the Delcath system must be proven to be safe and effective for the treatment of liver cancer. The FDA requires us to demonstrate that delivering doxorubicin using the Delcath system results in patient survival times that are longer than those obtained from administering chemotherapy agents intravenously. We have conducted Phase I and II human clinical trials at three United States medical centers under investigational device and investigational new drug exemptions granted by the FDA. The trials were designed to demonstrate the system's "functionality," or its ability to administer to and extract from the liver approved and marketed chemotherapy agents. Forty-four patients participated in the trials. Twenty-one of these test subjects had primary liver cancer or melanoma which had spread to the liver and were treated with doxorubicin. The remaining 23 test subjects suffered from other forms of liver cancer, and/or were treated with another chemotherapy agent, 5-FU. These trials demonstrated that the Delcath system was capable of extracting approximately 70% to 85% of the chemotherapy agent administered to the liver. We believe the results of the clinical trials we have conducted indicate that the Delcath system delivered (a) more chemotherapy agent to the tumor site, and (b) less chemotherapy agent to the general circulation than delivered by administration of the same dose by intravenous means. The Delcath system permits the delivery of higher dosages of chemotherapy agents to the cancer site. In addition, clinicians involved in the Phase I and Phase II clinical trials observed (a) reduction in tumor size and (b) the safety of the system at higher dosage levels of chemotherapy than those used in conventional intravenous chemotherapy delivery. Further, though not demonstrated in a statistically significant manner because of the limited number of patients, clinicians observed survival times of patients treated with the Delcath system which exceeded those that would generally be expected in patients receiving chemotherapy treatment through conventional intravenous means of delivery. The following table illustrates the survival periods of patients treated with the Delcath system since their diagnosis: Survival Time Since Diagnosis (Months) Percentage 6 4 12 33 18 22 24 11 30 18 36 8 42 0 48 0 >48 4 Based on the results of our clinical trials, we submitted to the FDA our application for pre-market approval of the Delcath system as a medical device. In response to our application, the FDA classified the Delcath system as a drug delivery system and requires us to obtain approval of a new drug application, or a supplemental new drug application, for the chemotherapy agent being administered by the Delcath system. 26

These applications must demonstrate the efficacy of a particular drug when administered through the Delcath system. To do so, we must demonstrate, in a statistically meaningful manner, that administering chemotherapy agents with the Delcath system results in survival times of patients that are longer than those obtained from administering chemotherapy agents intravenously. With a substantial portion of the proceeds from this offering, we intend to conduct Phase III human clinical trials designed to demonstrate that administering doxorubicin with the Delcath system to treat primary liver cancer and malignant melanoma that has spread to the liver results in patient survival times that are longer than those obtained from administering chemotherapy agents intravenously. In December 1999, the FDA approved the protocols for conducting the Phase III clinical trials. We expect the Phase III clinical trials to be conducted in at least 10 medical centers and to involve approximately 274 test subjects, of which 124 will be treated for primary liver cancer and 150 will be treated for malignant melanoma that has spread to the liver. Half of these test subjects will be treated with doxorubicin administered using the Delcath system and half, the control group, will be treated with chemotherapy agents delivered intravenously. We have identified and approached a number of medical centers that have expressed an interest in conducting the clinical trials. We expect that within 90 days after the closing of this offering we will begin to enter agreements with medical centers to conduct the clinical trials. As a result, we expect clinical trials to begin during the fourth quarter of this year. However, our timetable is subject to uncertainty and we cannot assure you that we can meet our planned schedule. We cannot assure you that all of the medical centers we have identified will be available to conduct the clinical trials when we are in a position to have them commence or that we will be ready to commence the trials within any particular time period. We intend to hire a contract research firm to conduct these trials. However, we have not begun negotiations with a contract research organization and we cannot assure you that we will be able to engage an organization on acceptable terms and conditions in a timely manner or at all. We believe that we will acquire sufficient data to obtain FDA approval of the Delcath system within 12 months of the commencement of the clinical trials. After acquiring sufficient data, we believe that our collation, analysis and submission of the trial results to the FDA will take an additional three months. Given the short life expectancy of liver cancer patients, we believe that the FDA will review our pre-market application expeditiously and will respond to our submission within three months. The trials may take longer to complete, however, because of difficulties we may encounter in entering into agreements with clinical testing sites to conduct the trials and the difficulties these sites may encounter in enrolling patients. The FDA may take longer than three months from the date we submit our trial results before granting marketing approval, or may not grant approval at all. Research for Hepatitis Treatment Another disease which attacks the liver is viral hepatitis. The incidence of viral hepatitis in the United States and worldwide is increasing. The long-range effects of some forms of hepatitis can include massive death of liver cells, chronic active hepatitis, cirrhosis and hepatoma. The current treatment for viral hepatitis is limited and includes long-term injections of interferon alpha, which is similar to chemotherapy in its toxicity and dosage limitations. We plan to seek a strategic partner to conduct clinical trials to determine the feasibility of using the Delcath system to administer anti-viral drugs, including interferon alpha, in the treatment of viral hepatitis. Sales and Marketing Our marketing efforts will focus on the 34 comprehensive cancer centers in the United States recognized by the National Cancer Institute, beginning with the hospitals participating in the Phase III clinical trials. We will focus these efforts on two distinct groups of medical specialists in these comprehensive cancer centers: (1) oncologists (who have primary responsibility for the patient) and (2) interventional radiologists (members of the hospital staff who work with catheter-based systems). Upon diagnosis of cancer, a patient is usually 27

referred to a medical oncologist. This physician generally provides palliative treatments and refers the patient to a surgical oncologist if surgery appears to be an option. Both medical and surgical oncologists will be included in our target market. Generally, oncologists do not position catheters, instead enlisting the assistance of an interventional radiologist. We plan to hire a marketing director at such time as we receive an indication from the FDA that approval of the Delcath system is forthcoming and then hire a sales manager and three sales representatives to market the system in the United States. In addition, we plan to utilize distributors and/or one or more corporate marketing partners to market products outside the United States. We believe distribution or corporate partnering arrangements will be cost effective, will be implemented more quickly than a direct sales force established by us in such countries and will enable us to capitalize on local marketing expertise in the countries we target. Nissho Agreement In December 1996, we entered into an agreement with Nissho Corporation, a large manufacturer and distributor of medical devices and pharmaceuticals based in Osaka, Japan which grants to Nissho the exclusive right to distribute the Delcath system in Japan, China, Korea, Hong Kong and Taiwan until December 31, 2004. Nissho, which has previously invested $1,000,000 in Delcath, has advised us that it expects to commence the clinical trials in Japan by the end of 2000. Nissho may also seek to conduct clinical trials in the other countries in the territory. Products covered by the agreement include the Delcath system for the treatment of cancer in the liver and the lower extremities, as well as new products which may be added by mutual agreement. Nissho is required to purchase products from Delcath in connection with clinical trials and for resale in its market at prices to be determined by mutual agreement. Nissho has agreed, in its territory, not to engage in the business of manufacturing, distributing or selling systems similar to the Delcath system for the liver or other organs or body regions. Third-Party Reimbursement Currently, because the Delcath system is characterized by the FDA as an experimental device, its use is not reimbursable in the United States. We will not seek to have third-party payors, such as Medicare, Medicaid and private health insurance plans, reimburse the use of the Delcath system until after its use is approved by the FDA. Even if approved by the FDA, these payors may require us, as a condition to reimbursement, to provide extensive supporting scientific, clinical and cost effectiveness data for our Delcath system to the American Medical Association. New products are under increased scrutiny with respect to a determination as to whether or not they will be covered by the various healthcare plans and with respect to the level of reimbursement which will be applicable to respective covered products and procedures. Third-party payors may deny reimbursement for the treatment and medical costs associated with the Delcath system, notwithstanding FDA or other regulatory approval, if it is determined that the Delcath system is unnecessary, inappropriate, not cost effective, experimental or for a non-approved indication. Third-party payors currently provide reimbursement for many of the components of the Delcath system based on established general reimbursement codes, in connection with their use in liver perfusion and other therapies. We believe that the Delcath system will provide significant cost savings to the extent that it can reduce treatment and hospitalization costs associated with the side effects of chemotherapy. Our planned wholesale price for the Delcath system kit is $4,000. A patient normally undergoes four treatments with the Delcath system, each requiring a new system kit. Each treatment with the system costs approximately $12,000, resulting in a total treatment cost of approximately $48,000. This compares to a total cost of conventional aggressive chemotherapy treatment of approximately $160,000 to $180,000, which includes the hospitalization and treatment costs associated with the side effects of the systemic delivery of chemotherapy agents. Manufacturing We plan to utilize contract manufacturers to produce the components of the Delcath system. In order to maintain quality control, we plan to perform final assembly and packaging in our own facility. If we undertake these operations our facility will be required to comply with the FDA's good manufacturing practice regulations. If we sell the Delcath system in some foreign markets, our facility will also need ISO 9000 approval from the European Union. 28

The double balloon catheter will be manufactured domestically by the Burron OEM division of B. Braun Medical, Inc. of Germany. The double balloon catheter must be manufactured in accordance with manufacturing and performance specifications that are on file with the FDA. Burron has demonstrated that the components it manufactures meet these specifications. Burron's manufacturing facility is ISO 9000 approved, which will allow the use of the catheter in European markets. B. Braun has experience in obtaining regulatory approval for medical products in European markets and has indicated informally, that it will assist us in this process. We have not entered into a written agreement with Burron to manufacture the catheter either for the Phase III clinical trials or for commercial sale. To ensure sufficient supply of catheters to complete the clinical trials, we intend to purchase our total trial requirements before commencement of the trials. Medtronic USA, Inc. manufactures the components of the blood filtration circuit located outside of the body, including the medical tubing through which a patient's blood flows and various connectors, as well as the blood filtration pump head. Medtronic is a manufacturer of components used for extracorporeal blood circulation during cardiac surgery. The components manufactured by Medtronic have been cleared by the FDA for other applications and can, therefore, be sourced off the shelf. These components, however, must comply with manufacturing and performance specifications for the Delcath system that are on file with the FDA. Medtronic has demonstrated that the components it manufactures meet these specifications. Medtronic's manufacturing facility is also ISO 9000 approved and, thus, the components it manufactures may be used in European markets. The activated charcoal filters used in the Delcath system are manufactured by Asahi Medical Products of Japan. These filters have been cleared by the FDA for other applications and can be sourced off the shelf. Asahi has demonstrated that the filters it supplies fall within the performance parameters and meet the specifications on file with the FDA. We have not entered into a written agreement with Asahi to supply the filters either for the Phase III clinical trials or for commercial sale. Competition Competition in the cancer treatment industry, and specifically the markets for systems and devices to improve the outcome of chemotherapy treatment for cancer, is intense. We believe that the primary competitive factors for products addressing cancer include safety, efficacy, ease of use, reliability and price. We also believe that physician relationships, especially relationships with leaders in the interventional radiology and oncology communities, are important competitive factors. Delcath competes with all forms of liver cancer treatments which are alternatives to resection including radiation, implanted infusion pumps, liver transplants, embolization, cryosurgery, radiowave ablation and the use of biological response modulators, monoclonal antibodies and liposomes. Many large pharmaceutical companies and research institutions are developing systems and devices to improve the outcome of chemotherapy treatment for cancer. Pfizer Corporation currently markets the Infusaid Pump, which has been successful in facilitating regional drug delivery. However, the Infusaid Pump lacks a means of preventing the entry of these agents into the patient's general circulation after they pass through the liver. Other companies, including Merck & Co., Inc., are developing various chemotherapy agents with reduced toxicity, while other companies are developing products to reduce the toxicity and side effects of chemotherapy treatment. In addition, gene therapy, vaccines and other minimally invasive procedures are currently being developed as alternatives to chemotherapy. Government Regulation United States Food and Drug Administration General. The manufacture and sale of medical devices and drugs are subject to extensive governmental regulation in the U.S. and in other countries. The Delcath system is regulated in the U.S. as a drug delivery system by the FDA under the Federal Food, Drug and Cosmetic Act and requires approval by the FDA of a pre-market approval application prior to commercial distribution. 29

Doxorubicin, the drug that we are initially seeking to have approved for delivery by the Delcath system, is a widely used chemotherapy agent which has been approved by the FDA since 1974. Like all approved drugs, it has approved label instructions which deal with such matters as indications for use, method of action, dosing, side effects and contraindications. Because the Delcath system delivers doxorubicin through a mode of administration and at dose levels which differ from those currently approved, we must obtain approval for revised labeling of a doxorubicin product providing for its use with the Delcath system. This will require the filing of a supplemental or an original new drug application for the administration of doxorubicin through the Delcath system. Under the Federal, Food, Drug and Cosmetic Act, the FDA regulates the pre-clinical and clinical testing, manufacture, labeling, distribution, sales, marketing, advertising and promotion of medical devices and drugs in the U.S. Noncompliance with applicable requirements, including good clinical practice requirements, can result in the refusal of the government to grant approvals, suspension or withdrawal of clearances or approvals, total or partial suspension of production, distribution, sales and marketing, fines, injunctions, civil penalties, recall or seizure of products, and criminal prosecution of a company and its officers and employees. Our contract manufacturers also are subject to numerous federal, state and local laws relating to such matters as safe working conditions, manufacturing practices, environmental protection, fire hazard control and disposal of hazardous or potentially hazardous substances. Medical Devices. The Delcath system is a Class III medical device. It is subject to the most stringent controls applied by the FDA to reasonably assure safety and effectiveness. An application for pre-market approval must be supported by data, typically including the results of animal and laboratory testing and human clinical trials. Before commencing clinical trials, we obtained an investigational device exemption providing for the initiation of clinical trials. We also obtained approval of our investigational plan, including the proposed protocols and informed consent statement that patients signed before undergoing treatment with the Delcath system, by the institutional review boards at the sites where the trials were conducted. Under the Federal Food, Drug and Cosmetic Act, clinical studies for "significant risk" Class III devices require obtaining such approval by institutional review boards and the filing with the FDA of an investigational device exemption at least 30 days before initiation of the studies. Given the short life expectancy of liver cancer patients, we believe the FDA will review our pre-market application expeditiously and respond to our submission of the Delcath system for commercial sale within three months. However, approval of the Delcath system may take longer if the FDA requests substantial additional information or clarification, or if any major amendments to the application are filed. The FDA will usually inspect the applicant's manufacturing facility to ensure compliance with quality systems regulations prior to approval of an application. The FDA also may conduct bioresearch monitoring inspections of the clinical trial sites and the applicant to ensure data integrity, and that the studies were conducted in compliance with the applicable FDA regulations, including good clinical practice regulations. If the FDA's evaluations of the application, clinical study sites and manufacturing facilities are favorable, the FDA will issue either an approval letter (order), or an "approvable letter" containing a number of conditions that must be met in order to secure approval of an application. If and when those conditions have been fulfilled to the satisfaction of the FDA, the agency will issue an order approving the application, authorizing commercial marketing of the device under specified conditions of use. If the FDA's evaluation of the application, the clinical study sites or the manufacturing facilities are not favorable, the FDA will deny approval of the application or issue a "not approvable letter." The FDA may also determine that additional pre-clinical testing or human clinical trials are necessary. The FDA's regulations require agency approval of an application supplement for changes to a device if they affect the safety and effectiveness of the device, including new indications for use; labeling changes; the use of a different facility or establishment to manufacture, process, or package the device; changes in vendors supplying components for the device; changes in manufacturing methods or quality control systems; and changes in performance or design specifications. Changes in manufacturing procedures or processes may be implemented and the device distributed 30 days after the FDA is provided with notice of these changes unless the FDA advises the pre-market approval application holder within 30 days of receipt of the notice that the notice is inadequate or that preapproval of an application supplement is required. 30

Approved medical devices remain subject to extensive regulation. Advertising and promotional activities are subject to regulation by the FDA and, in some instances, by the Federal Trade Commission. Other applicable requirements include the FDA's medical device reporting regulations, which require that we provide information to the FDA on deaths or serious injuries alleged to have been associated with the use of marketed devices, as well as product malfunctions that would likely cause or contribute to a death or serious injury if the malfunction were to recur. If safety or efficacy problems occur after the product reaches the market, the FDA may take steps to prevent or limit further marketing of the product. Additionally, the FDA actively enforces regulations prohibiting marketing or promotion of devices or drugs for indications or uses that have not been cleared or approved by the FDA. Further, the Food, Drug and Cosmetic Act authorizes the FDA to impose post-market surveillance requirements with respect to a Class III device which is reasonably likely to have a serious adverse health consequence or which is intended to be implanted in the human body for more than one year or to be a life sustaining or life supporting device used outside a device user facility. The Food, Drug and Cosmetic Act regulates a device manufacturer's quality control and manufacturing procedures by requiring the manufacturer to demonstrate and maintain compliance with quality systems including good manufacturing practice requirements as specified in the FDA quality systems regulations. These regulations require, among other things, that (i) the manufacturing process be regulated, controlled, and documented by the use of written procedures and (ii) the ability to produce devices which meet the manufacturer's specifications be validated by extensive and detailed testing of every aspect of the process. The FDA monitors compliance with quality systems regulations, including good manufacturing practice requirements, by conducting periodic inspections of manufacturing facilities. If violations of the applicable regulations are found during FDA inspections, the FDA will notify the manufacturer of such violations and the FDA, administratively or through court enforcement action, can prohibit further manufacturing, distribution, sales and marketing of the device until the violations are cured. If violations are not cured within a reasonable length of time after the FDA provides notification of such violations, the FDA is authorized to withdraw approval of the pre-market approval application. Investigational devices that require FDA marketing approval in the United States but have not received such approval, may be exported to countries belonging to the European Union, European Economic Area, and to some other specified countries, provided that the device is intended for investigational use in accordance with the laws of the importing country; has been manufactured in accordance with the FDA's good manufacturing practices; is labeled on the outside of the shipping carton "for export only," is not sold or offered for sale in the United States; and complies with the specifications of the foreign purchaser. The export of an investigational device for investigational use to any other country requires prior authorization from the FDA. An investigational device may be exported for commercial use only as described below, under "Foreign Regulation." Drugs. We, or a manufacturer of a chemotherapy agent, must obtain FDA approval of a supplemental or original new drug application for a chemotherapy product providing for its use with the Delcath system before the system may be marketed in the U.S. to deliver that agent to the liver or any other site. Clinical trials to support the relabeling of doxorubicin to provide for its use with the Delcath system must be conducted in accordance with the FDA's investigational new drug regulations. Phase III trial protocols have been approved by the FDA under the Company's investigational new drug application. FDA regulations also require that prior to initiating the trials the sponsor of the trials obtain investigational review board approval from each investigational site that will conduct the trials. We have identified ten medical centers that have expressed an interest in conducting the trials. The investigational review boards at two of these medical centers have given their approval to have the clinical trials conducted at their institutions. We are seeking the approval of investigational review boards at additional medical centers by assembling and providing them with information with respect to the trials. The FDA requires that, in order to obtain approval to relabel doxorubicin for delivery using the Delcath system, we demonstrate that delivering doxorubicin using the system results in patient survival times that are longer than those obtained from administering chemotherapy agents intravenously. The approved Phase III trial protocols are designed to obtain approval of both a new drug application (or a supplemental new drug application) and a pre-market approval application providing for the use of 31

doxorubicin with the Delcath system. The trial protocols were approved by both the FDA division that approves new drugs and the division that reviews applications to market new devices. All of the data generated in the trials will be submitted to both of these FDA divisions. If we successfully complete the clinical trials, we believe the manufacturer of doxorubicin will submit to the FDA a new drug application or supplemental new drug application and pre-market approval to deliver doxorubicin to the liver through the Delcath system. Under the Food, Drug and Cosmetic Act, the Delcath system cannot be marketed until the new drug application (or supplemental new drug application) and pre-market approval application approvals are obtained, and then only in conformity with conditions of use set forth in the approved labeling. Foreign Regulation. In order for us to market our products in Asia, Europe, Latin America and other foreign jurisdictions, we must obtain required regulatory approvals or clearances and otherwise comply with extensive regulations regarding safety and manufacturing processes and quality. These regulations, including the requirements for approvals or clearances to market, may differ from the FDA regulatory scheme. In addition, there may be foreign regulatory barriers other than pre-market approval or clearance. In April 1996, new FDA legislation was enacted that permits that a medical device which requires FDA marketing approval but which has not received such approval to be exported to any country for commercial use, provided that the device (i) complies with the laws of that country, (ii) has valid marketing authorization or the equivalent from the appropriate authority in any of a list of industrialized countries including Australia, Canada, Israel, Japan, New Zealand, Switzerland, South Africa and countries in the European Economic Union, and (iii) meets other regulatory requirements regarding labeling, compliance with the FDA's good manufacturing practices and notification to the FDA. We must obtain a CE mark in order for us to market and sell the Delcath system in the European Union, except for limited use as a clinical trial device. Patents, Trade Secrets and Proprietary Rights Our success depends in large part on our ability to obtain patents, maintain trade secret protection and operate without infringing on the proprietary rights of third parties. Because of the length of time and expense associated with bringing new products through development and regulatory approval to the marketplace, the health care industry has traditionally placed considerable importance on obtaining patent and trade secret protection for significant new technologies, products and processes. We hold the following six United States patents, as well as three corresponding foreign patents in Canada, Europe and Japan: Summary Description of Patents Patent No. - ------------------------------------------------------------------ ---------------- Isolated perfusion method for cancer treatment U.S. #5,069,662 Isolated perfusion device -- catheter for use in isolated perfusion in cancer treatment U.S. #5,411,479 Device and method for isolated pelvic perfusion U.S. #5,817,046 Catheter design to allow blood flow from renal veins and limbs to bypass occluded segment of IVC U.S. #5,893,841 Balloon inside catheter to restrict blood flow or prevent catheter from moving U.S. #5,897,533 Catheter with slideable balloon to adjust isolated segment U.S. #5,919,163 We plan to vigorously enforce our intellectual property rights. In addition, we will conduct searches and other activity relating to the protection of existing patents and filing of new applications. Litigation may be necessary to enforce any patents issued or assigned to us or to determine the scope and validity of third party proprietary rights. Litigation would be costly and divert our attention from our business. 32

If others file patent applications with respect to inventions for which we already have issued patents or have patent applications pending, we may be forced to participate in interference proceedings declared by the United States Patent and Trademark Office to determine priority of invention, which would also be costly and divert our attention from our business. In addition to patent protection, we rely on unpatented trade secrets and proprietary technological expertise. We rely, in part, on confidentiality agreements with our marketing partners, employees, advisors, vendors and consultants to protect our trade secrets and proprietary technological expertise. Employees As of April 30, 2000, we had five employees, four of whom are full-time. We intend to recruit additional personnel in connection with the research, development, manufacturing and marketing of our products. None of our employees is represented by a union, and we believe relationships with our employees are good. Our success will depend, in large part, upon our ability to attract and retain qualified employees. We face competition in this regard from other companies, research institutions and other organizations. In addition to our full time employees, we engage the services of medical and scientific consultants. Facilities We lease and occupy approximately 3,300 square feet of office space in Stamford, Connecticut. We have occupied these facilities since 1992. Our lease extends through December 2000 with a monthly rental of approximately $7,500. We have prepaid our rent through December 2000. We believe that we will require additional space in 2001, and are beginning site selection for rental property in the same building or nearby and believe that satisfactory space is available at commercially reasonable rates. 33

The underwriter has not yet exercised its right to designate a person. Classified Board of Directors Our board of directors is divided into three classes of directors serving staggered three-year terms. As a result, approximately one-third of the board of directors will be elected each year. These provisions, together with the provision of our amended and restated certificate of incorporation and by-laws, allow the board of directors to fill vacancies on or increase the size of the board of directors, and may deter a stockholder from removing incumbent directors and filling such vacancies with its own nominees in order to gain control of the board. Each of our directors has been elected to serve until his successor has been elected and duly qualified. The directorship terms of Dr. Herschkowitz and Mr. Koly will expire at the annual meeting of stockholders in 2002; the directorship term of Mr. Mancuso will expire at the annual meeting of stockholders in 2001; and the directorship terms of Dr. Sorrentino and Mr. Bergman will expire at the annual meeting of stockholders in 2003. We have established an audit committee and a stock option and compensation committee.

In addition, the audit committee reviews the scope and results of the audit with the independent accountants, reviews with management and the independent accountants our annual operating results, considers the adequacy of our internal accounting procedures and considers and reports to the board of directors with respect to other auditing and accounting matters, fees to be paid to our independent auditors and the performance of our independent auditors. After this offering, the audit committee will consist of Messrs. Bergman and Mancuso and Dr. Sorrentino. The stock option and compensation committee reviews and recommends to the board of directors the salaries, benefits and stock option grants of all employees, consultants, directors and other individuals compensated by us. The stock option and compensation committee also administers our stock option and other employee benefits plans. The compensation committee currently consists of Mr. Koly, Dr. Sorrentino and Mr. Bergman. Mr. Bergman currently chairs the compensation committee. Director Compensation Directors who are employees of Delcath do not currently receive any compensation for serving on the board of directors.

Currently, non-employee directors do not receive any compensation. A new compensation rate for these directors will be established in our next shareholders meeting. In addition, each non-employee director received a one-time grant in January 1999 of 35

options to purchase 43,704 shares of common stock at a price of $3.89 per share, all of which are vested. Each non-employee director received a separate one-time grant in December 1999 of options to purchase 28,408 shares of common stock at a price of $2.29 per share, half of which are vested, the remainder to vest in December 2000. Scientific Advisors and Consultants We seek to expand the breadth of expertise and experience available to us through the use of consultants and advisors. We coordinate these advisors, including nineteen M.D.s and Ph.D.s to organize, conduct, and monitor clinical and pre-clinical testing, regulatory filings and responses, product development and manufacturing, and publication and presentation of the results of our research. These individuals bring a broad range of competencies to our operations. The scientific advisors are independent professionals who meet on an individual basis with management when so requested. We seek as scientific advisors recognized experts in relevant sciences or clinical medicine to advise us about present and long-term scientific planning, research and development. There is no fixed term of service for the scientific advisors. Current members may resign or be removed at any time, and additional members may be appointed. Members do not serve on an exclusive basis with Delcath, are not under contract (other than with respect to confidentiality obligations) and are not obligated to present corporate opportunities to us. To our knowledge, none of the members is working on the development of competitive products. Inventions or products developed by a scientific advisor who is not otherwise affiliated with us will not become our property. Scientific advisors who are not affiliated with us are paid a per diem fee for their services. All members receive reimbursement for expenses incurred in traveling to and attending meetings on behalf of Delcath.

Stock Option Plans On October 15, 1992, our board of directors and stockholders adopted our 1992 incentive stock option plan and our 1992 non-incentive stock option plan. On June 15, 2000, the board of directors adopted our 2000 stock option plan. Our 2000 stock option plan will be submitted for stockholder approval at our next annual meeting. We have reserved 299,375 shares of common stock for issuance upon exercise of options granted from time to time under the 1992 incentive stock option plan, 260,041 shares of common stock for issuance upon exercise of options granted from time to time under the 1992 non-incentive stock option plan and 300,000 shares of common stock for issuance from time to time under the 2000 stock option plan. The stock option plans are intended to assist us in securing and retaining key employees, directors and consultants by allowing them to participate in our ownership and growth through the grant of incentive and non-qualified options. Under the 1992 incentive stock option plan we may grant incentive stock options only to key employees and employee directors. Under the 1992 non-incentive stock option plan, we may grant non-qualified options to our employees, officers, directors, consultants, agents and independent contractors. Under the 2000 stock option plan, we may grant incentive or non-qualified options to our officers, employees, directors, consultants, agents and independent contractors. The stock option plans are administered by a committee, currently the stock option and compensation committee, appointed by our board of directors. Subject to the provisions of each of the stock option plans, the committee will determine who shall receive options, the number of shares of common stock that may be purchased under the options, the time and manner of exercise of options and exercise prices. The term of options granted under each of the stock option plans may not exceed ten years, or five years for an incentive stock option granted to an optionee owning more than 10% of our voting stock. The exercise price for incentive stock options shall be equal to or greater than 100% of the fair market value of the shares of the common stock at the time granted; provided that incentive stock options granted to an optionee owning more than 10% of our voting stock shall be exercisable at a price equal to or greater than 110% of the fair market value of the common stock on the date of the grant. The exercise price for non-qualified options will be set by the committee, in its discretion, but in no event shall the exercise price be less than the fair market value of the shares of common stock on the date of grant. Shares of common stock received upon exercise of options granted under each of the plans will be subject to restrictions on sale or transfer. As of the date of this prospectus, we have granted incentive stock options to purchase 299,375 shares of common stock under our 1992 incentive stock option plan at a weighted average price of $3.18 and non-incentive stock options to purchase 260,041 shares of common stock under our 1992 non-incentive stock option plan at a weighted average price of $3.36. All of these options have been granted to our officers and directors and terminate on the fifth anniversary of their vesting date. We will not grant any additional options under these plans. As of the date of this prospectus, we have not granted any options under our 2000 stock option plan. Each of our stock option plans includes a provision that an optionholder, upon exercise of an option, must execute a stockholder's agreement containing provisions to be determined by Delcath at the time of such exercise. 38

Limitation on Liability and Indemnification Matters As authorized by the Delaware General Corporation Law, our certificate of incorporation provides that none of our directors shall be personally liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director, except for liability for: o any breach of the director's duty of loyalty to Delcath or its stockholders; o acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; o unlawful payments of dividends or unlawful stock redemptions or repurchases; or o any transaction from which the director derived an improper personal benefit. This provision limits our rights and the rights of our stockholders to recover monetary damages against a director for breach of the fiduciary duty of care except in the situations described above. This provision does not limit our rights or the rights of any stockholder to seek injunctive relief or rescission if a director breaches his duty of care. In addition, our certificate of incorporation provides that if the Delaware General Corporation Law is amended to further limit the liability of a director, then the liability of the directors shall be eliminated or limited to the fullest extent permitted by such amendment. These provisions will not alter the liability of directors under federal securities laws. Our certificate of incorporation further provides for the indemnification of any and all persons who serve as our director, officer, employee or agent to the fullest extent permitted under the Delaware General Corporation Law. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons under the above provisions, or otherwise, we have been advised that in the opinion of the SEC indemnification is against public policy as expressed in the Securities Act, and is unenforceable. We maintain a policy of insurance under which our directors and officers are insured, subject to the limits of the policy, against certain losses arising from claims made against our directors and officers by reason of any acts or omissions covered under this policy in their capacities as directors or officers, including liabilities under the Securities Act. 39

In July 1999, we sold an aggregate of 59,514 shares of common stock and three-year warrants to purchase an aggregate of 6,609 shares of common stock at $11.74 per share for aggregate proceeds of $776,192. Mr. Mancuso made a $75,000 investment for which he received 5,750 shares of common stock and warrants to purchase 639 shares of common stock. In April 2000, we issued 292,426 shares of common stock to existing security holders and their designees for proceeds of $501,825 in a rights offering. Each of M.S. Koly, Samuel Herschkowitz, our Chairman and Chief Technical Officer, and James Sorrentino, a director of Delcath, purchased 14,859 shares for $25,500, and William Bergman, a director of Delcath, purchased 8,741 shares for $15,000. DESCRIPTION OF SECURITIES Upon the closing of this offering, the authorized capital stock of Delcath will consist of 15,000,000 shares of common stock, $.01 par value per share, and 10,000,000 shares of preferred stock, $.01 par value per share, whose rights and designation have not yet been established. There will be no preferred stock outstanding immediately after the closing of this offering. The description in the sections below of Delcath's certificate of incorporation and by-laws refers to Delcath's Amended and Restated Certificate of Incorporation and Amended and Restated By-Laws, respectively, as they will be in effect upon the closing of this offering. Common Stock Immediately prior to the closing of this offering, there will be 3,418,732 shares of common stock outstanding. After giving effect to the issuance of the 2,000,000 shares of common stock offered by this prospectus, assuming the underwriters do not exercise their overallotment option, there will be 5,418,732 shares of common stock outstanding upon the closing of this offering. Holders of common stock are entitled to one vote for each share on all matters submitted to a stockholder vote. Holders of common stock do not have cumulative voting rights. Therefore, holders of a majority of the shares of common stock voting for the election of directors can elect all of the directors. Holders of common stock are entitled to share in all dividends that the board of directors, in its discretion, declares from legally available funds. In any liquidation, dissolution or winding up of Delcath, each outstanding share entitles its holder to participate pro rata in all assets that remain after payment of liabilities and after providing for each class of stock, if any, having preference over the common stock. 41

Holders of common stock have no conversion, preemptive or other subscription rights, and there are no redemption provisions applicable to the common stock. The rights of the holders of common stock are subject to any rights that may be fixed for holders of preferred stock, when and if any preferred stock is issued. All outstanding shares of common stock are, and the shares underlying all options and warrants will be, duly authorized, validly issued, fully paid and non-assessable upon our issuance of these shares. Preferred Stock Under Delcath's certificate of incorporation, Delcath's board of directors is authorized, subject to certain limitations prescribed by law, without further stockholder approval, from time to time to issue up to an aggregate of 10,000,000 shares of preferred stock. The preferred stock may be issued in one or more series. Each series may have different rights, preferences and designations and qualifications, limitations and restrictions that may be established by Delcath's board of directors without approval from the stockholders. These rights, designations and preferences include: o number of shares to be issued; o dividend rights; o right to convert the preferred stock into a different type of security; o voting rights attributable to the preferred stock; o right to set aside assets for payments relating to the preferred stock; and o prices to be paid upon redemption of the preferred stock or a bankruptcy type event. If Delcath's board of directors decides to issue any preferred stock, it could have the effect of delaying or preventing another party from taking control of Delcath. This is because the terms of the preferred stock could be designed to make it prohibitively expensive for any unwanted third party to make a bid for the shares of Delcath. We have no present plans to issue any new shares of preferred stock. Options and Warrants We have reserved 21,852 shares of common stock for issuance upon exercise of non-plan options. These options are exercisable at any time on or prior to February 4, 2002 at a price of $2.29 per share. We have also reserved for issuance 21,468 shares of common stock for issuance upon outstanding warrants to purchase common stock at $8.58 and $11.74 per share which expire, respectively, on January 16, 2001 and March 2, 2002. Also, the underwriters will receive five-year warrants to purchase 200,000 shares. The exercise of any of these options and warrants will dilute the percentage ownership of our other stockholders. Anti-Takeover Effects of Delaware Law and Delcath's Amended and Restated Certificate of Incorporation and By-Laws We are subject to the provisions of Section 203 of the Delaware General Corporation Law. That section provides, with exceptions, that a Delaware corporation may not engage in any of a broad range of business combinations with a person or his affiliate or associate who is an owner of 15% or more of the outstanding voting stock of the corporation for a period of three years from the date that this person became an interested stockholder. Our board of directors is divided into three classes of directors serving staggered three-year terms. As a result, approximately one-third of the board of directors will be elected each year. These provisions, when coupled with the provisions of our amended and restated certificate of incorporation authorizing the board of directors to fill vacant directorships or increase the size of the board of directors, may deter a stockholder from removing incumbent directors and simultaneously gaining control of the board of directors by filling the vacancies created by that removal with its own nominees. 42

Transfer Agent and Warrant Agent The transfer agent for our common stock and warrants is American Stock Transfer & Trust Company, 40 Wall Street, New York, New York 10005. SHARES ELIGIBLE FOR FUTURE SALE After the closing of this offering, we will have 5,418,732 shares of common stock issued and outstanding of which the 2,000,000 shares offered by this prospectus will be freely tradable without restriction or further registration under the Securities Act, except for any shares purchased by any affiliate of us. An affiliate of us is generally a person who has a controlling position with regard to us. Any shares purchased by our affiliates will be subject to the resale limitations of Rule 144 promulgated under the Securities Act. All of the approximately 3,418,732 remaining shares of common stock that will be outstanding, are restricted securities as that term is defined under Rule 144. Approximately 2,010,574 of these shares are immediately eligible for sale and the remaining 1,408,158 shares will become eligible, at various times, beginning 90 days following the date of this prospectus, in each case, subject to the contracted provisions below. The holders of all of our common stock, including each of our officers, directors and principal stockholders, have agreed not to sell or dispose of any of the shares of common stock held by them, including in accordance with Rule 144, for a period of twelve months following the date of this prospectus without the underwriter's prior written consent. For the second year following the closing, our officers, directors and principal shareholders have agreed that, without the underwriter's written consent, they will not sell any shares of common stock during any three-month period in excess of the amount they would be allowed to sell if they were deemed an affiliate of ours and the shares were deemed restricted as defined under Rule 144 of the Securities Act. This volume is the greater of: (a) 1% of the then outstanding common stock; and (b) the average weekly trading volume of the common stock during the four calendar weeks preceding a sale. In general, under Rule 144, as currently in effect, beginning 90 days after the date of this prospectus, a person or group of persons whose shares are aggregated, who has beneficially owned restricted shares for at least one year, including the holding period of any prior owner except an affiliate of us, would be entitled to sell, within any three month period, a number of shares that does not exceed the greater of: o 1% of the then outstanding common stock; or o The average weekly trading volume of our common stock during the four calendar weeks preceding the sale, provided, that, public information about us as required by Rule 144 is available and the seller complies with manner of sale provisions and notice requirements. The volume limitations described above, but not the one-year holding period, also apply to sales of our non-restricted securities by affiliates of us. A person who is not an affiliate, has not been an affiliate within three months before the sale and has beneficially owned the restricted securities for at least two years, is entitled to sell the restricted shares under Rule 144 without regard to any of the limitations described above. Before this offering, there was no public market for our common stock. We cannot predict the effect, if any, that sales of, or the availability for sale of, our common stock will have on the market price of our common stock prevailing from time to time. Nevertheless, the possibility that substantial amounts of common stock in the public market, including shares issuable upon the exercise of outstanding warrants or options, could adversely affect the prevailing market price of our common stock and could impair our ability to raise capital in the future through the sale of securities. 43

UNDERWRITING Whale Securities Co., L.P., as underwriter, has agreed, subject to the terms and conditions contained in the underwriting agreement relating to this offering, to purchase the 2,000,000 shares of common stock offered by us. The underwriting agreement provides that the obligations of the underwriter are subject to the delivery of an opinion of our counsel and to various other conditions. The underwriter is committed to purchase and pay for all of the shares offered by this prospectus if any of those shares are purchased. The underwriter has advised us that it proposes to offer our shares to the public at the public offering price indicated on the cover page of this prospectus. The underwriter may allow selected dealers who are members of the National Association of Securities Dealers, Inc., known as the NASD, concessions, not in excess of $.___ per share, of which not in excess of $.___ per share may be reallowed to other dealers who are members of the NASD. We have granted to the underwriter an option, exercisable not later than 45 days after the date of this prospectus, to purchase up to 300,000 shares at the public offering price indicated on the cover page of this prospectus, less the underwriting discounts and commissions. The underwriter may exercise this option only to cover over-allotments, if any, made in connection with the sale of the common shares offered by this prospectus. If the underwriter exercises its over-allotment in full, the total price to the public would be US $13,800,000, the total underwriting discounts and commissions would be $1,380,000 and the total proceeds to us, before payment of the expenses of this offering, would be $12,420,000. We have agreed to pay to the underwriter a non-accountable expense allowance equal to 3% of the gross proceeds from the sale of the shares offered by us, including any securities sold pursuant to the underwriter's over-allotment option, of which $50,000 has been paid as of the date of this prospectus. We have also agreed to pay all expenses in connection with qualifying the shares offered under the laws of the states as the underwriter may designate, including expenses of counsel retained for this purpose by the underwriter. We estimate our expenses of this offering to be $2,000,000, including the underwriter's discounts and commission, or $2,234,000 if the underwriter's over-allotment option is completely exercised. At the closing of this offering, we will sell to the underwriter and its designees, for an aggregate of $100, underwriter's warrants to purchase up to 200,000 shares. The underwriter's warrants are exercisable at any time, in whole or in part, during the five-year period commencing on the date of this prospectus at an exercise price of $9.90 per share, 165% of the public offering price per share. During the first year following the date of this prospectus, the underwriter's warrants are assignable or transferable only to the officers and partners of the underwriter and members of the selling group. During the exercise period, the holders of the underwriter's warrants will have the opportunity to profit from a rise in the market price of the shares, which will dilute the interests of our stockholders. We expect that the underwriter's warrants will be exercised when we would, in all likelihood be able to obtain any needed capital on terms more favorable to us than those provided in the underwriter's warrants. Any profit realized by the underwriter on the sale of the underwriter's warrants or the underlying shares of common stock may be deemed additional underwriting compensation. The underwriter's warrants contain a cashless exercise provision. We have agreed that, upon the request of the holders of the majority of the underwriter's warrants, we will, at our own expense, on one occasion during the exercise period register the underwriter's warrants and the shares underlying the underwriter's warrants under the Securities Act. We have also agreed to include the underwriter's warrants and all underlying shares in any appropriate registration statement which is filed by us under the Securities Act during the seven years following the date of this prospectus. We have agreed, for a period of three years from the date of this prospectus, if so requested by the underwriter, to nominate and use our best efforts to elect a designee of the underwriter as a director of Delcath or, at the underwriter's option, as a non-voting advisor to our board of directors. Our officers, directors and current stockholders have agreed to vote their shares in favor of the underwriter's designee. The underwriter has not yet exercised its right to designate a person. The holders of all of our outstanding shares of common stock, options and warrants have agreed not to sell or dispose in another manner any of those securities in the public markets for a period of twelve months 44

form the date of this prospectus without the underwriter's prior written consent. For the second year following the closing, our officers, directors and principal stockholders have agreed that without the underwriter's written consent they will not sell any shares of common stock during any three-month period in excess of the amount they would be allowed to sell if they were deemed an affiliate of ours and the shares were deemed restricted as defined under Rule 144 of the Securities Act. This amount is the greater of: (a) 1% of the then outstanding common stock; and (b) the average weekly trading volume of the common stock during the four calendar weeks preceding the sale. We have agreed to indemnify the underwriter against civil liabilities, including liabilities under the Securities Act. The underwriter has informed us that it does not expect sales of the securities offered to discretionary accounts to exceed 1% of the shares offered by this prospectus. Before this offering, there has been no public market for our common stock. Accordingly, the initial public offering price of the common stock has been determined by negotiation between us and the underwriter and may not necessarily be related to our asset value, net worth or other established criteria of value. Factors considered in determining this price include our financial condition and prospects, an assessment of our management, market prices of similar securities of comparable publicly-traded companies, financial and operating information of companies engaged in activities similar to our business and the general condition of the securities market. In connection with this offering, the underwriter may engage in passive market making transactions in the shares on Nasdaq in accordance with Rule 103 of Regulation M promulgated under the Exchange Act. In connection with this offering, the underwriter may engage in transactions that stabilize, maintain or affect in another manner the price of our common shares. These transactions may include stabilization transactions permitted by Rule 104 of Regulation M, under which persons may bid for or purchase shares to stabilize the market price. Specifically, the underwriter may over-allot in connection with the offering, creating a short position in our common shares for its own account. In addition, to cover over-allotments or to stabilize the price of our common shares, the underwriter may bid for, and purchase, shares in the open market. The underwriter may also reclaim selling concessions allowed to a dealer for distributing the common shares in the offering, if the underwriter repurchases previously distributed shares in transactions to cover short positions, in stabilization transactions or in another manner. Any of these activities may stabilize or maintain the market price of our common stock above independent market levels. The underwriter is not required to engage in these activities, and may end any of these activities at any time. LEGAL MATTERS The validity of the common stock and warrants offered hereby will be passed upon for Delcath by Morse, Zelnick, Rose & Lander, LLP, New York, New York. Morse, Zelnick, Rose & Lander, LLP owns an aggregate 125,000 shares of our common stock.

Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.

DELCATH SYSTEMS, INC. (A Development Stage Company) Notes to Financial Statements December 31, 1999 and 1998 (1) Description of Business and Summary of Significant Accounting Policies (a) Description of Business Delcath Systems, Inc. (the "Company") is a development stage company which was founded in 1988 for the purpose of developing and marketing a proprietary drug delivery system capable of introducing, and removing, high dose chemotherapy agents to a diseased organ system while greatly inhibiting their entry into the general circulation system. It is hoped that the procedure will result in a meaningful treatment for cancer. In November 1989, the Company was granted an IDE (Investigational Device Exemption) and an IND status (Investigational New Drug) for its product by the FDA (Food and Drug Administration). (b) Basis of Financial Statement Presentation The accounting and financial reporting policies of the Company conform to generally accepted accounting principles. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make assumptions and estimates that impact the amounts reported in those statements. Such assumptions and estimates are subject to change in the future as additional information becomes available or as circumstances are modified. Actual results could differ from these estimates. (c) Furniture and Fixtures Furniture and fixtures are recorded at cost and are being depreciated over the estimated useful lives of the assets. (d) Income Taxes The Company accounts for income taxes following the asset and liability method in accordance with Statement of Financial Accounting Standards (SFAS) No. 109, "Accounting for Income Taxes." Under such method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. The Company's income tax returns are prepared on the cash basis of accounting. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years that the asset is expected to be recovered or the liability settled. (e) Stock Option Plan The Company has historically accounted for its employee stock option plans in accordance with the provisions of Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to Employees," and related interpretations. As such, compensation expense is recorded on the date of grant only if the current fair market value of the underlying stock exceeds the exercise price. Fair market values of the Company's common stock at the dates options were granted were based on third party sales of stock at or around the dates options were granted, or in the absence of such transactions, based on a determination by the board of directors based on current available information. In 1996, the Company adopted Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based Compensation," which permits entities to recognize as expense over the vesting period the fair value of all stock-based awards on the date of grant. Alternatively, SFAS No. 123 also allows entities to continue to apply the provisions of APB Opinion No. 25 and provide pro forma net income and pro forma earnings per share disclosures for employee stock option grants made in 1995 and future years as if the fair-value-based method defined in SFAS No. 123 had been applied. The Company has elected to continue to apply the provisions of APB Opinion No. 25 and provide the pro forma disclosure provisions of SFAS No. 123 (see note 2(e)). F-7

DELCATH SYSTEMS, INC. (A Development Stage Company) Notes to Financial Statements December 31, 1999 and 1998 -- (Continued) (1) Description of Business and Summary of Significant Accounting Policies -- (Continued) (f) Earnings Per Share Basic earnings per share is computed using the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share reflect the dilutive effect of common stock equivalents using the treasury stock method. (g) Statements of Cash Flows For purposes of the statements of cash flows, the Company considers highly liquid debt instruments with original maturities of three months or less to be cash equivalents. At December 31, 1999 cash equivalents included commercial paper of $557,000. (h) Interim Financial Information The financial statements and notes related thereto as of March 31, 2000 and for the three months ended March 31, 1999 and 2000 are unaudited, but in the opinion of management, include all normal recurring adjustments necessary for a fair presentation of financial position and results of operations. The operating results for the interim periods are not necessarily indicative of a full year's operations. (2) Stockholders' Equity The common stock and per share data for all periods gives effect to a reverse stock split of 1 for 2.2881 shares which is to occur immediately before the date of the Company's initial public offering described in note 5.

(b) Voting Rights Each holder of common stock is entitled to one vote. Each share of class A preferred stock and each share of class B preferred stock is convertible into shares of common stock on a one for .4370 basis, subject to antidilution adjustments. In addition to special voting rights to elect directors to the Board of Directors, each class A preferred stockholder is entitled to ten times the number of votes per share of common stock into which the class A preferred stock is convertible and each class B preferred stockholder is entitled to the number of votes per share of Common Stock into which the class B preferred stock is convertible. (c) Liquidation Preference In the event of any liquidation, dissolution or winding up of the Company, after provision for payment of debts and other liabilities, the holders of the class A preferred stock shall be entitled to receive, prior to any F-10

DELCATH SYSTEMS, INC. (A Development Stage Company) Notes to Financial Statements December 31, 1999 and 1998 -- (Continued) (2) Stockholders' Equity -- (Continued) distribution of any of the assets or surplus funds of the Company to the holders of class B preferred stock and common stock, an amount equal to the sum of (a) 150% of the issue price (as adjusted for any combinations, consolidations, stock distributions or stock dividends with respect to such shares) plus (b) a sum equal to that amount of interest that would have accrued if a sum equal to 150% of the issue price had been invested at a compounded annual interest rate of 10% at the original issue date. After the satisfaction of the class A preferred stockholders, the holders of class B preferred stock will be entitled to a liquidation sum, in preference to the common stockholders, of $3.90 per share. Common stockholders will be entitled to share ratably with the class A and class B preferred stockholders (on an as-converted basis) in the remaining assets of the Company. (d) Dividends The holders of class A and class B preferred stock are entitled to receive dividends on a cumulative basis at the rate of 11% and 8%, respectively, per share per annum as and when declared by the Board of Directors, before any dividend or distribution is declared, set apart for, or paid upon the common stock of the Company. As of December 31, 1999, class A preferred stock and class B preferred stock had dividends in arrears of $624,740 ($.31 per share) and $759,429 ($1.82 per share), respectively. Dividends declared but unpaid, at the option of the holder, are payable in cash or may be converted into common stock subject to antidilution adjustments. The class A dividends may be converted at the rate of $.57 per share, while the class B dividends may be converted at the rate of $5.83 per share. The Company has entered into agreements with the preferred shareholders providing that if the Company completes a public offering of its common stock prior to September 30, 2001, the Board will, immediately prior to the offering, declare as payable all dividends in arrears. In such event, the preferred shareholders have agreed to accept one-third of such dividends in cash and then immediately convert all of their outstanding preferred stock into common stock as well as convert the balance of their declared but unpaid preferred stock dividends into common stock at the applicable conversion price. (e) Stock Option Plans The Company established an Incentive Stock Option Plan and a Non-Incentive Stock Option Plan under which stock options may be granted. Additionally, the Company has entered into separate contracts apart from the Incentive Stock Option Plan and the Non-Incentive Stock Option Plan under which options to purchase common shares have been granted. A stock option granted allows the holder of the option to purchase a share of the Company's common stock in the future at a stated price. The Plans are administered by the Board of Directors which determines the individuals to whom the options shall be granted as well as the terms and conditions of each option grant, the option price and the duration of each option. The Company's Incentive and Non-Incentive Stock Plans were approved and became effective on November 1, 1992. The Incentive Stock Options vest as determined by the Company and expire over varying terms, but not more than five years from the date of grant. Stock option activity for the period January 1, 1998 through December 31, 1999 is as follows: F-11

Had compensation cost for the Company's stock option grants been determined based on the fair value at the grant dates consistent with the methodology of SFAS 123, the Company's net loss for the years ended December 31, 1998 and 1999 would have been increased to the pro forma amounts indicated as follows: 1998 1999 ----------------- ------------- Net loss: As reported $ (2,049,980) (572,581) Pro forma (2,132,139) (944,303) The per share weighted average fair value of stock options granted during 1999 and 1998 was $.73, estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions used for the grants for both years: no dividend yield, risk free interest rate of 5.5%, expected lives of five years and no volatility.

DELCATH SYSTEMS, INC. (A Development Stage Company) Notes to Financial Statements December 31, 1999 and 1998 -- (Continued) (3) Income Taxes As of December 31, 1999, the Company had net operating loss carryforwards for federal income tax purposes of approximately $8,542,000 which are available to offset future federal taxable income, if any, through 2019. The net operating loss carryforwards resulted in a deferred tax asset of approximately $2,904,000 at December 31, 1999. Management does not expect the Company to be taxable in the near future and has established a 100% valuation allowance against the deferred tax asset created by the net operating loss carryforwards. (4) Prepaid Rent and Due From Affiliate The Company leases office space on a month to month basis under a sublease from an affiliate. The Company has deposited $24,000 with the affiliate as a rent deposit and in March 2000 prepaid its rent for the period through December 31, 2000. The affiliate has in turn paid such amounts to its landlord. (5) Initial Public Offering In March 2000, the Company engaged an investment banker for the purpose of issuing its stock in an initial public offering. In connection therewith, the Company anticipates declaring and paying the preferred stock dividends as described in note 2(d); converting all then outstanding preferred stock to common stock as described in note 2(d) and effecting a reverse split of the common shares of 1 for 2.2881 shares. (6) Subsequent Events Stock Issuances During April 2000, the Company sold 292,426 shares at $1.72 per share to existing stockholders in a rights offering yielding proceeds to the Company of $501,825.

PART II. INFORMATION NOT REQUIRED IN THE PROSPECTUS Item 24. Indemnification of Directors and Officers Section 145 of the General Corporation Law of the State of Delaware provides for the indemnification of officers and directors under certain circumstances against expenses incurred in successfully defending against a claim and authorizes a Delaware corporation to indemnify its officers and directors under certain circumstances against expenses and liabilities incurred in legal proceedings involving such persons because of their being or having been an officer or director. Section 102(b) of the Delaware General corporation Law permits a corporation, by so providing in its certificate of incorporation, to eliminate or limit a director's liability to the corporation and its stockholders for monetary damages arising out of certain alleged breaches of their fiduciary duty. Section 102(b)(7) provides that no such limitation of liability may affect a director's liability with respect to any of the following: (i) breaches of the director's duty of loyalty to the corporation or its stockholders; (ii) acts or omissions not made in good faith or which involve intentional misconduct of knowing violations of law; (iii) liability for dividends paid or stock repurchased or redeemed in violation of the Delaware General Corporation law; or (iv) any transaction from which the director derived an improper personal benefit. Section 102(b)(7) does not authorize any limitation on the ability of the company or its stockholders to obtain injunctive relief, specific performance or other equitable relief against directors. Article Seventh of the Registrant's Certificate of Incorporation provides that the personal liability of the directors of the Registrant be eliminated to the fullest extent permitted under Section 102(b) of the Delaware General Corporation law. Article Eighth of the Registrant's Certificate of Incorporation and the Registrant's By-laws provides that all persons whom the Registrant is empowered to indemnify pursuant to the provisions of Section 145 of the Delaware General Corporation law (or any similar provision or provisions of applicable law at the time in effect), shall be indemnified by the Registrant to the full extent permitted thereby. The foregoing right of indemnification shall not be deemed to be exclusive of any other rights to which those seeking indemnification may be entitled under any by-law, agreement, vote of stockholders or disinterested directors, or otherwise. Insofar as indemnification for liabilities under the Securities Act of 1933, as amended (the "Securities Act") may be permitted to directors, officers or persons controlling the Registrant pursuant to the foregoing provisions, the Registrant has been informed that in the opinion of the Commission, such indemnification is against public policy as expressed in the Securities Act and is therefor unenforceable. Reference is made to the Underwriting Agreement, the proposed form of which is filed as Exhibit 1.1, pursuant to which the underwriter agrees to indemnify the directors and certain officers of the Registrant and certain other persons against certain civil liabilities. Item 25. Other Expenses of Issuance and Distribution The following table sets forth the expenses (other than the underwriting discounts and commissions and the representative's non-accountable expense allowance) expected to be incurred in connection with the issuance and distribution of the securities being registered. All of such expenses are estimates, other than the filing fees payable to the Securities and Exchange Commission and the National Association of Securities Dealers, Inc. II-1

Item 26. Recent Sales of Unregistered Securities Since January 1997, the Registrant has issued securities without registration under the Securities Act in the following transactions: 1. From September 1997 through January 1998, the Registrant issued an aggregate of 114,446 shares of Common Stock to eleven investors, including Venkol Ventures LP, Venkol Ventures Ltd. and a director of the Registrant for aggregate proceeds of $1,275,000. In April 1998, the eleven investors also received three-year warrants to purchase 14,859 shares of common stock at $8.58 per share. 2. In December 1997, the Registrant issued an aggregate of 17,482 shares of Common Stock to an employee upon the exercise of non-incentive stock options for aggregate proceeds of $26,000. 3. In December 1997, the Registrant issued an aggregate of 2,970 shares of Common Stock valued at $25,485 to a consultant as compensation for consulting services. 4. In April 1998, the Registrant issued an aggregate of 10,926 shares of common stock to a venture capital firm upon the exercise of non-incentive stock options for aggregate proceeds of $67,500. 5. In September 1998, the Registrant issued an aggregate of 4,370 shares of common stock to an investor for aggregate proceeds of $57,000. 6. In April 1999, the Registrant issued an aggregate of 2,913 shares of common stock to a venture capital firm upon the exercise of warrants for aggregate proceeds of $24,998. 7. In July 1999, the Registrant issued an aggregate of 59,514 shares of Common Stock and warrants entitling the holders thereof to purchase an aggregate of 6,609 shares of Common Stock to twelve investors, at $11.74 per share, including a director of the Registrant, for aggregate proceeds of $776,192. 8. In April 2000, the Registrant issued an aggregate of 282,426 shares of common stock to 14 security holders and their designees for aggregate proceeds of $501,825 The sales and issuances of the Common Stock, options and warrants in each transaction described above were deemed to be exempt from registration under the Securities Act in reliance upon Section 4(2) of the Securities Act as transactions not involving a public offering. The Registrant made a determination that each of the purchasers was a sophisticated investor. The purchasers in such private offerings represented their intention to acquire the securities for investment only and not with a view to the distribution thereof. Appropriate legends were affixed to the stock certificates and warrants issued in each transaction. All purchasers had adequate access, through their employment or other relationships, to sufficient information about the Registrant to make an informed investment decision. None of the securities was sold through an underwriter and, accordingly, there were no underwriting discounts or commissions involved. II-2

(d) The conditions for use of a registration statement on Form SB-2 set forth in the General Instructions to Form SB-2 have been satisfied with respect to the Company, the transactions contemplated herein and in the Registration Statement.

The Company has good title to all personal property (tangible and intangible) owned by it, free and clear of all security interests, charges, mortgages, liens, encumbrances and defects, except such as are described in the Registration Statement and Prospectus or such as do not materially affect the value or transferability of such property and do not interfere with the use of such property made, or proposed to be made, by the Company.

(b) The Company will use its best efforts to cause the Registration Statement to become effective and will advise the Underwriter immediately, and, if requested by the Underwriter, confirm such advice in writing, (i) when the Registration Statement, or any post-effective amendment to the Registration Statement or any supplemented Prospectus is filed with the Commission; (ii) of the receipt of any comments from the Commission; (iii) of any request of the Commission for amendment or supplementation of the Registration Statement or Prospectus or for additional information; and (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of any Preliminary Prospectus, or of the suspension of the qualification of the Shares for offering or sale in any jurisdiction, or of the initiation of any proceedings for any of such purposes. The Company will use its best efforts to prevent the issuance of any such stop order or of any order preventing or suspending such use and to obtain as soon as possible the lifting thereof, if any such order is issued. (c) The Company will deliver to the Underwriter, without charge, from time to time until the Effective Date, as many copies of each Preliminary Prospectus as the Underwriter may reasonably request, and the Company hereby consents to the use of such copies for purposes permitted by the Act. The Company will deliver to the Underwriter, without charge, as soon as the Registration Statement becomes effective, and thereafter from time to time as requested, such number of copies of the Prospectus (as supplemented, if the Company makes any supplements to the Prospectus) as the Underwriter may reasonably request. The Company has furnished or will furnish to the Underwriter a signed copy of the Registration Statement as originally filed and of all amendments thereto, whether filed before or after the Registration Statement becomes effective, a copy of all exhibits filed therewith and a signed copy of all consents and certificates of experts.

If, at any time when a prospectus relating to the Shares is required to be delivered under the Act, any event occurs as a result of which the 15

Registration Statement and Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or if it shall be necessary to amend or supplement the Registration Statement and Prospectus to comply with the Act or the regulations thereunder, the Company will promptly file with the Commission, subject to Section 5(a) hereof, an amendment or supplement which will correct such statement or omission or which will effect such compliance. (e) The Company will furnish such proper information as may be required and otherwise cooperate in qualifying the Shares for offering and sale under the securities or Blue Sky laws relating to the offering in such jurisdictions as the Underwriter may reasonably designate, provided that no such qualification will be required in any jurisdiction where, solely as a result thereof, the Company would be subject to service of general process or to taxation or qualification as a foreign corporation doing business in such jurisdiction. (f) The Company will make generally available to its securityholders, in the manner specified in Rule 158(b) under the Act, and deliver to the Underwriter and Underwriter's Counsel as soon as practicable and in any event not later than 45 days after the end of its fiscal quarter in which the first anniversary date of the effective date of the Registration Statement occurs, an earning statement meeting the requirements of Rule 158(a) under the Act covering a period of at least 12 consecutive months beginning after the effective date of the Registration Statement. (g) For a period of five years from the Effective Date, the Company will deliver to the Underwriter and to Underwriter's Counsel on a timely basis (i) a copy of each report or document, including, without limitation, reports on Forms 8-K, 10-K (or 10-KSB), 10-Q (or 10-QSB) and exhibits thereto, filed or furnished to the Commission, any securities exchange or the National Association of Securities Dealers, Inc. (the "NASD") on the date each such report or document is so filed or furnished; (ii) as soon as practicable, copies of any reports or communications (financial or other) of the Company mailed to its securityholders; (iii) as soon as practicable, a copy of any Schedule 13D, 13G, 14D-1 or 13E-3 received or prepared by the Company from time to time; (iv) 16

monthly statements setting forth such information regarding the Company's results of operations and financial position (including balance sheet, profit and loss statements and data regarding outstanding purchase orders) as is regularly prepared by management of the Company; and (v) such additional information concerning the business and financial condition of the Company as the Underwriter may from time to time reasonably request and which can be prepared or obtained by the Company without unreasonable effort or expense. The Company will furnish to its stockholders annual reports containing audited financial statements and such other periodic reports as it may determine to be appropriate or as may be required by law. (h) Neither the Company nor any person that controls, is controlled by or is under common control with the Company will take any action designed to or which might be reasonably expected to cause or result in the stabilization or manipulation of the price of the Common Shares. (i) If the transactions contemplated by this Agreement are consummated, the Underwriter shall retain the $50,000 previously paid to it, and the Company will pay or cause to be paid the following: all costs and expenses incident to the performance of the obligations of the Company under this Agreement, including, but not limited to, the fees and expenses of accountants and counsel for the Company; the preparation, printing, mailing and filing of the Registration Statement (including financial statements and exhibits), Preliminary Prospectuses and the Prospectus, and any amendments or supplements thereto; the printing and mailing of the Selected Dealer Agreement, the issuance and delivery of the Shares to the Underwriter; all taxes, if any, on the issuance of the Shares; the fees, expenses and other costs of qualifying the Shares for sale under the Blue Sky or securities laws of those states in which the Shares are to be offered or sold, including fees and disbursements of counsel in connection therewith, and including those of such local counsel as may have been retained for such purpose; the filing fees incident to securing any required review by the NASD and either the Boston Stock Exchange or Pacific Stock Exchange; the cost of printing and mailing the "Blue Sky Survey"; the cost of furnishing to the Underwriter copies of the Registration Statement, Preliminary Prospectuses and the Prospectus as herein provided; the costs of placing "tombstone advertisements" in any publications which may be selected by the Underwriter; and all other costs and expenses incident to the performance of the Company's obligations hereunder which are not otherwise specifically provided for in this Section 5(i). 17

In addition, at the Closing Date or the Option Closing Date, as the case may be, the Underwriter will deduct from the payment for the Offered Shares or any Optional Shares three percent (3%) of the gross proceeds of the offering (less the sum of $50,000 previously paid to the Underwriter), as payment for the Underwriter's nonaccountable expense allowance relating to the transactions contemplated hereby, which amount will include the fees and expenses of Underwriter's Counsel (other than the fees and expenses of Underwriter's Counsel relating to Blue Sky qualifications and registrations, which, as provided for above, shall be in addition to the three percent (3%) nonaccountable expense allowance and shall be payable directly by the Company to Underwriter's Counsel on or prior to the Closing Date). (j) If the transactions contemplated by this Agreement or related hereto are not consummated because the Company decides not to proceed with the offering for any reason or because the Underwriter decides not to proceed with the offering as a result of a breach by the Company of its representations, warranties or covenants in the Agreement or as a result of adverse changes in the affairs of the Company, then the Company will be obligated to reimburse the Underwriter for its accountable expenses up to the sum of $75,000, inclusive of the $50,000 previously paid to the Underwriter by the Company. In all cases other than those set forth in the preceding sentence, if the Company or the Underwriter decide not to proceed with the offering, the Company will only be obligated to reimburse the Underwriter for its accountable expenses up to $25,000, and inclusive of the amounts previously paid to the Underwriter by the Company. In no event, however, will the Underwriter, in the event the offering is terminated, be entitled to retain or receive more than an amount equal to its actual accountable out-of-pocket expenses. (k) The Company intends to apply the net proceeds from the sale of the Shares for the purposes set forth in the Prospectus. Except as set forth in the Prospectus, no portion of the net proceeds from the sale of the Shares will be used to repay any indebtedness. (l) During the period of twelve (12) months from the Effective Date hereof, neither the Company nor any of its officers, directors or 18

securityholders will offer for sale or sell or otherwise dispose of, directly or indirectly, any securities of the Company, in any manner whatsoever, whether pursuant to Rule 144 of the Regulations or otherwise, and no holder of registration rights relating to securities of the Company will exercise any such registration rights, in either case, without the prior written consent of the Underwriter. During the 12-month period commencing one year from the date hereof, no officer, director or securityholder who beneficially owns or holds 5% or more of the outstanding Common Shares (calculated in accordance with Rule 13d-3(d)(i) under the Exchange Act) may sell any Common Shares in excess of the amount that they would be allowed to sell if they were deemed "affiliates" of the Company and their shares were deemed "restricted," as those terms are defined in Rule 144 promulgated under the Securities Act, without the prior written consent of the Underwriter. (m) The Company will not file any registration statement relating to the offer or sale of any of the Company's securities, including any registration statement on Form S-8, during the twelve (12) months from the Effective Date, without the Underwriter's prior written consent. (n) The Company maintains and will continue to maintain a system of internal accounting controls sufficient to provide reasonable assurances that: (i) transactions are executed in accordance with management's general or specific authorization; (ii) transactions are recorded as necessary in order to permit preparation of financial statements in accordance with generally accepted accounting principles and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with management's general or specific authorization; and (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences. (o) The Company will use its best efforts to maintain the listing of the Shares on the Nasdaq SmallCap Market and will, if so qualified, list the Shares, and maintain such listing for so long as qualified, on the Nasdaq National Market System.

(q) Subject to the sale of the Offered Shares, the Underwriter and its successors will have the right to designate a nominee for election, at its or their option, either as a member of or a non-voting advisor to the Board of Directors of the Company (which board, during such period, shall meet at least quarterly, have no members who are related (by marriage or otherwise) to any of its Board members, and be comprised of members, a majority of which are not otherwise affiliated with the Company, its management or its founders), and the Company will use its best efforts to cause such nominee to be elected and continued in office as a director of the Company or as such advisor until the expiration of three (3) years from the Effective Date. Each of the Company's current officers, directors and stockholders agree to vote all of the Common Shares owned by such person or entity so as to elect and continue in office such nominee of the Underwriter. Following the election of such nominee as a director or advisor, such person shall receive no more or less compensation than is paid to other non-officer directors of the Company for attendance at meetings of the Board of Directors of the Company and shall be entitled to receive reimbursement for all reasonable costs incurred in attending such meetings including, but not limited to, food, lodging and transportation. The Company agrees to indemnify and hold such director or advisor harmless, to the maximum extent permitted by law, against any and all claims, actions, awards and judgments arising out of his service as a director or advisor and, in the event the Company maintains a liability insurance policy affording coverage for the acts of its officers and directors, to include such director or advisor as an insured under such policy. The rights and benefits of such indemnification and the benefits of such insurance shall, to the extent possible, extend to the Underwriter insofar as it may be or may be alleged to be responsible for such director or advisor. If the Underwriter does not exercise its option to designate a member of or advisor to the Company's Board of Directors, the Underwriter shall nonetheless have the right to send a representative (who need not be the same individual from meeting to meeting) to observe each meeting of the Board of Directors. The Company agrees to give the Underwriter notice of each such meeting and to provide the Underwriter with an agenda and minutes of the meeting no later than it gives such notice and provides such items to the directors. 20

(v) For a period of five (5) years from the Effective Date, the Company shall provide the Underwriter, on a not less than annual basis, with internal forecasts setting forth projected results of operations for each quarterly and annual period in the two (2) fiscal years following the respective dates of such forecasts.

(vii) The descriptions in the Registration Statement and the Prospectus of statutes, regulations, government classifications, contracts and other documents (including opinions of such counsel); and the response to Item 13 of Form SB-2 have been reviewed by Company Counsel, and, based upon such review, are accurate in all material respects and present fairly the information required to be disclosed, and there are no material statutes, regulations or government classifications, or, to the best of Company Counsel's knowledge, material contracts or documents, of a character required to be described in the Registration Statement or the Prospectus or to be filed as exhibits to the Registration Statement, which are not so described or filed as required.

(ix) The issuance and sale of the Shares have been duly authorized and, when the Shares have been issued and duly delivered against payment therefor as contemplated by this Agreement, the Shares will be validly issued, fully paid and nonassessable, and the holders thereof will not be subject to personal liability solely by reason of being such holders. The Shares are not subject to preemptive rights of any stockholder of the Company. The certificates representing the Shares are in proper legal form.

Holders of Common Shares issuable upon exercise of the Underwriter's Warrants will not be subject to personal liability solely by reason of being such holders. Neither the Underwriter's Warrants nor the Common Shares issuable upon exercise thereof will be subject to preemptive rights of any stockholder of the Company. The Company has reserved a sufficient number of Common Shares from its authorized, but unissued Common Shares for issuance upon exercise of the Underwriter's Warrants in accordance with the provisions of the Underwriter's Warrant Agreement. The Underwriter's Warrants conform to the descriptions thereof in the Registration Statement and Prospectus. (xi) Upon delivery of the Offered Shares to the Underwriter against payment therefor as provided in this Agreement, the Underwriter (assuming it is a bona fide purchaser within the meaning of the Uniform Commercial Code) will acquire good title to the Offered Shares, free and clear of all liens, encumbrances, equities, security interests and claims. (xii) Assuming that the Underwriter exercises the over-allotment option to purchase any of the Optional Shares and makes payment therefor in accordance with the terms of this Agreement, upon delivery of the Optional Shares to the Underwriter hereunder, the Underwriter (assuming it is a bona fide purchaser within the meaning of the Uniform Commercial Code) will acquire good title to such Optional Shares, free and clear of any liens, encumbrances, equities, security interests and claims. 28

(xiii) To the best of Company Counsel's knowledge, there are no claims, actions, suits, proceedings, arbitrations, investigations or inquiries before any governmental agency, court or tribunal, foreign or domestic, or before any private arbitration tribunal, pending or threatened against the Company, or involving the Company's properties or businesses, other than as described in the Prospectus, such description being accurate, and other than litigation incident to the kind of business conducted by the Company which, individually and in the aggregate, is not material. (xiv) The Company owns or possesses adequate and enforceable rights to use all patents, patent applications, trademarks, service marks, copyrights, rights, trade secrets, confidential information, processes and formulations used or proposed to be used in the conduct of its business as described in the Prospectus (collectively the "Intangibles"); to the best of Company Counsel's knowledge, the Company has not infringed nor is infringing with the rights of others with respect to the Intangibles; and, to the best of Company Counsel's knowledge, the Company has not received any notice that it has or may have infringed, is infringing upon or is conflicting with the asserted rights of others with respect to the Intangibles which might, singly or in the aggregate, materially adversely affect its business, results of operations or financial condition and such counsel is not aware of any licenses with respect to the Intangibles which are required to be obtained by the Company other than those licenses which the Company has obtained. The opinions described in this Section 6(b)(xiv) may be given by Company Counsel in reliance on the opinion of an attorney, reasonably acceptable to Underwriter's Counsel, practicing in the patent area. Company Counsel has participated in reviews and discussions in connection with the preparation of the Registration Statement and the Prospectus, and in the course of such reviews and discussions and such other investigation as Company Counsel deemed necessary, no facts came to its attention which lead it to believe that (A) the Registration Statement (except as to the financial statements and other financial data contained therein, as to which Company Counsel need not express an opinion), on the Effective Date, contained any untrue statement of a material fact required to be stated therein or omitted to state any material fact required to be stated therein or necessary 29

to make the statements therein, in light of the circumstances under which they were made, not misleading, or that (B) the Prospectus (except as to the financial statements and other financial data contained therein, as to which Company Counsel need not express an opinion) contains any untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Each counsel giving an opinion must give the opinion set forth in this paragraph as to such subject matter of its opinion. In rendering its opinion pursuant to this Section 6(b), Company Counsel may rely upon the certificates of government officials and officers of the Company as to matters of fact, provided that Company Counsel shall state that they have no reason to believe, and do not believe, that they are not justified in relying upon such opinions or such certificates of government officials and officers of the Company as to matters of fact, as the case may be. The opinion letters delivered pursuant to this Section 6(b) shall state that any opinion given therein qualified by the phrase "to the best of our knowledge" is being given by Company Counsel after due investigation of the matters therein discussed. (c) At the Closing Date, there will have been delivered to the Underwriter a signed opinion of Underwriter's Counsel, dated as of the Closing Date, to the effect that the opinions delivered pursuant to Section 6(b) hereof appear on their face to be appropriately responsive to the requirements of this Agreement, except to the extent waived by the Underwriter, specifying the same, and with respect to such related matters as the Underwriter may require. (d) At the Closing Date (i) the Registration Statement and the Prospectus and any amendments or supplements thereto will contain all material statements which are required to be stated therein in accordance with the Act and the Regulations and will conform in all material respects to the requirements of the Act and the Regulations, and neither the Registration Statement nor the Prospectus nor any amendment or supplement thereto will contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; (ii) 30

since the respective dates as of which information is given in the Registration Statement and the Prospectus, there will not have been any material adverse change in the financial condition, results of operations or general affairs of the Company from that set forth or contemplated in the Registration Statement and the Prospectus, except changes which the Registration Statement and the Prospectus indicate might occur after the Effective Date; (iii) since the respective dates as of which information is given in the Registration Statement and the Prospectus, there shall have been no material transaction, contract or agreement entered into by the Company, other than in the ordinary course of business, which would be required to be set forth in the Registration Statement and the Prospectus, other than as set forth therein; and (iv) no action, suit or proceeding at law or in equity will be pending or, to the best of the Company's knowledge, threatened against the Company which is required to be set forth in the Registration Statement and the Prospectus, other than as set forth therein, and no proceedings will be pending or, to the best of the Company's knowledge, threatened against the Company before or by any federal, state or other commission, board or administrative agency wherein an unfavorable decision, ruling or finding would materially adversely affect the business, property, financial condition or results of operations of the Company, other than as set forth in the Registration Statement and the Prospectus. At the Closing Date, there will be delivered to the Underwriter a certificate signed by the Chairman of the Board or the President or a Vice President of the Company, dated the Closing Date, evidencing compliance with the provisions of this Section 6(d) and stating that the representations and warranties of the Company set forth in Section 4 hereof were accurate and complete in all material respects when made on the date hereof and are accurate and complete in all material respects on the Closing Date as if then made; that the Company has performed all covenants and complied with all conditions required by this Agreement to be performed or complied with by the Company prior to or as of the Closing Date; and that, as of the Closing Date, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been initiated or, to the best of his knowledge, are contemplated or threatened. In addition, the Underwriter will have received such other and further certificates of officers of the Company as the Underwriter or Underwriter's Counsel may reasonably request. 31

(e) At the time that this Agreement is executed and at the Closing Date, the Underwriter will have received a signed letter from KPMG LLP, dated the date such letter is to be received by the Underwriter and addressed to it, confirming that it is a firm of independent public accountants within the meaning of the Act and Regulations and stating that: (i) insofar as reported on by them, in their opinion, the financial statements of the Company included in the Prospectus comply as to form in all material respects with the applicable accounting requirements of the Act and the applicable Regulations; (ii) on the basis of procedures and inquiries (not constituting an examination in accordance with generally accepted auditing standards) consisting of a reading of the unaudited interim financial statements of the Company, if any, appearing in the Registration Statement and the Prospectus and the latest available unaudited interim financial statements of the Company, if more recent than that appearing in the Registration Statement and Prospectus, inquiries of officers of the Company responsible for financial and accounting matters as to the transactions and events subsequent to the date of the latest audited financial statements of the Company, and a reading of the minutes of meetings of the stockholders, the Board of Directors of the Company and any committees of the Board of Directors, as set forth in the minute books of the Company, nothing has come to their attention which, in their judgment, would indicate that (A) during the period from the date of the latest financial statements of the Company appearing in the Registration Statement and Prospectus to a specified date not more than three business days prior to the date of such letter, there have been any decreases in net current assets or net assets as compared with amounts shown in such financial statements or decreases in net sales or decreases [increases] in total or per share net income [loss] compared with the corresponding period in the preceding year or any change in the capitalization or long-term debt of the Company, except in all cases as set forth in or contemplated by the Registration Statement and the Prospectus, and (B) the unaudited interim financial statements of the Company, if any, appearing in the Registration Statement and the Prospectus, do not comply as to form in all material respects with the applicable accounting requirements of the Act and the Regulations or are not fairly presented in conformity with generally accepted accounting principles and practices on a basis substantially consistent with the audited financial statements included in the Registration Statement or the Prospectus; and (iii) they have compared specific dollar amounts, numbers of shares, numerical data, percentages of revenues and earnings, and other financial information pertaining to the Company set forth in the Prospectus (with respect to all dollar amounts, numbers of shares, percentages and other financial information contained in the Prospectus, to the extent that such amounts, numbers, percentages and information may be derived from the general accounting records of the Company, and excluding any questions requiring an interpretation by legal counsel) with the results obtained from the application of specified readings, inquiries and other appropriate procedures (which procedures do not constitute an examination in accordance with generally accepted auditing standards) set forth in the letter, and found them to be in agreement. 32

(f) There shall have been duly tendered to the Underwriter certificates representing the Offered Shares to be sold on the Closing Date. (g) The NASD shall have indicated that it has no objection to the underwriting arrangements pertaining to the sale of the Shares by the Underwriter.

The Company represents at the date hereof, and shall represent as of the Closing Date or Option Closing Date, as the case may be, that it has no knowledge that any such action is in fact contemplated by the Commission or the NASD. (i) The Company meets the current and any existing and proposed criteria for inclusion of the Shares on Nasdaq SmallCap Market. (j) All proceedings taken at or prior to the Closing Date or the Option Closing Date, as the case may be, in connection with the authorization, issuance and sale of the Shares shall be reasonably satisfactory in form and substance to the Underwriter and to Underwriter's Counsel, and such counsel shall have been furnished with all such documents, certificates and opinions as they may request for the purpose of enabling them to pass upon the matters referred to in Section 6(c) hereof and in order to evidence the accuracy and completeness of any of the representations, warranties or statements of the Company, the performance of any covenants of the Company, or the compliance by the Company with any of the conditions herein contained. 33

stated therein or necessary in order to make the statements therein not misleading, in light of the circumstances under which they were made, but only insofar as any such statement or omission was made in reliance upon and in conformity with information furnished in writing to the Company in connection therewith by the Underwriter expressly for use therein. (c) Promptly after receipt of notice of the commencement of any action in respect of which indemnity may be sought against any indemnifying party under this Section 7, the indemnified party will notify the indemnifying party in writing of the commencement thereof, and the indemnifying party will, subject to the provisions hereinafter stated, assume the defense of such action (including the employment of counsel satisfactory to the indemnified party and the payment of expenses) insofar as such action relates to an alleged liability in respect of which indemnity may be sought against the indemnifying party. After notice from the indemnifying party of its election to assume the defense of such claim or action, the indemnifying party shall no longer be liable to the indemnified party under this Section 7 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that if, in the reasonable judgment of the indemnified party or parties, it is advisable for the indemnified party or parties to be represented by separate counsel, the indemnified party or parties shall have the right to employ a single counsel to represent the indemnified parties who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the indemnified parties thereof against the indemnifying party, in which event the fees and expenses of such separate counsel shall be borne by the indemnifying party. Any party against whom indemnification may be sought under this Section 7 shall not be liable to indemnify any person that might otherwise be indemnified pursuant hereto for any settlement of any action effected without such indemnifying party's consent, which consent shall not be unreasonably withheld. 8. Contribution. To provide for just and equitable contribution, if (i) an indemnified party makes a claim for indemnification pursuant to Section 7 hereof (subject to the limitations thereof) and it is finally determined, by a judgment, order or decree not subject to further appeal, that such claim for indemnification may not be enforced, even though this Agreement expressly provides for indemnification in such case; or (ii) any indemnified or indemnifying party seeks contribution under the Act, the Exchange 36

Act, or otherwise, then the Company (including, for this purpose, any contribution made by or on behalf of any director of the Company, any officer of the Company who signed the Registration Statement and any controlling person of the Company) as one entity and the Underwriter (including, for this purpose, any contribution by or on behalf of each person, if any, who controls the Underwriter within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act and each officer, director, partner, employee and agent of the Underwriter) as a second entity, shall contribute to the losses, liabilities, claims, damages and expenses whatsoever to which any of them may be subject, so that the Underwriter is responsible for the proportion thereof equal to the percentage which the underwriting discount per Share set forth on the cover page of the Prospectus represents of the initial public offering price per Share set forth on the cover page of the Prospectus and the Company is responsible for the remaining portion; provided, however, that if applicable law does not permit such allocation, then, if applicable law permits, other relevant equitable considerations such as the relative fault of the Company and the Underwriter in connection with the facts which resulted in such losses, liabilities, claims, damages and expenses shall also be considered. The relative fault, in the case of an untrue statement, alleged untrue statement, omission or alleged omission, shall be determined by, among other things, whether such statement, alleged statement, omission or alleged omission relates to information supplied by the Company or by the Underwriter, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement, alleged statement, omission or alleged omission. The Company and the Underwriter agree that it would be unjust and inequitable if the respective obligations of the Company and the Underwriter for contribution were determined by pro rata or per capita allocation of the aggregate losses, liabilities, claims, damages and expenses or by any other method of allocation that does not reflect the equitable considerations referred to in this Section 8. No person guilty of a fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) will be entitled to contribution from any person who is not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person, if any, who controls the Underwriter within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act and each officer, director, partner, employee and agent of the Underwriter will have the same rights to contribution as the Underwriter, and each person, if any, who controls the Company within the 37

meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, each officer of the Company who has signed the Registration Statement and each director of the Company will have the same rights to contribution as the Company, subject in each case to the provisions of this Section 8. Anything in this Section 8 to the contrary notwithstanding, no party will be liable for contribution with respect to the settlement of any claim or action effected without its written consent. This Section 8 is intended to supersede, to the extent permitted by law, any right to contribution under the Act or the Exchange Act or otherwise available. 9. Survival of Indemnities, Contribution, Warranties and Representations. The respective indemnity and contribution agreements of the Company and the Underwriter contained in Sections 7 and 8 hereof, and the representations and warranties of the Company contained herein shall remain operative and in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of the Underwriter, the Company or any of its directors and officers, or any controlling person referred to in said Sections, and shall survive the delivery of, and payment for, the Shares. 10. Termination of Agreement. (a) The Company, by written or telegraphic notice to the Underwriter, or the Underwriter, by written or telegraphic notice to the Company, may terminate this Agreement prior to the earlier of (i) 11:00 A.M., New York City time, on the first full business day after the Effective Date; or (ii) the time when the Underwriter, after the Registration Statement becomes effective, releases the Offered Shares for public offering. The time when the Underwriter "releases the Offered Shares for public offering" for the purposes of this Section 10 means the time when the Underwriter releases for publication the first newspaper advertisement, which is subsequently published, relating to the Offered Shares, or the time when the Underwriter releases for delivery to members of a selling group copies of the Prospectus and an offering letter or an offering telegram relating to the Offered Shares, whichever will first occur. (b) This Agreement, including without limitation, the obligation to purchase the Shares and the obligation to purchase the Optional Shares after exercise of the option referred to in Section 3 hereof, are subject 38

to termination in the absolute discretion of the Underwriter, by notice given to the Company prior to delivery of and payment for all the Offered Shares or such Optional Shares, as the case may be, if, prior to such time, any of the following shall have occurred: (i) the Company withdraws the Registration Statement from the Commission or the Company does not or cannot expeditiously proceed with the public offering; (ii) the representations and warranties in Section 4 hereof are not materially correct or cannot be complied with; (iii) trading in securities generally on the New York Stock Exchange or the American Stock Exchange will have been suspended; (iv) limited or minimum prices will have been established on either such Exchange; (v) a banking moratorium will have been declared either by federal or New York State authorities; (vi) any other restrictions on transactions in securities materially affecting the free market for securities or the payment for such securities, including the Offered Shares or the Optional Shares, will be established by either of such Exchanges, by the Commission, by any other federal or state agency, by action of the Congress or by Executive Order; (vii) trading in any securities of the Company shall have been suspended or halted by any national securities exchange, the NASD or the Commission; (viii) there has been a materially adverse change in the condition (financial or otherwise), prospects or obligations of the Company; (ix) the Company will have sustained a material loss, whether or not insured, by reason of fire, flood, accident or other calamity; (x) any action has been taken by the government of the United States or any department or agency thereof which, in the judgment of the Underwriter, has had a material adverse effect upon the market or potential market for securities in general; or (xi) the market for securities in general or political, financial or economic conditions will have so materially adversely changed that, in the judgment of the Underwriter, it will be impracticable to offer for sale, or to enforce contracts made by the Underwriter for the resale of, the Offered Shares or the Optional Shares, as the case may be. (c) If this Agreement is terminated pursuant to Section 6 hereof or this Section 10 or if the purchases provided for herein are not consummated because any condition of the Underwriter's obligations hereunder is not satisfied or because of any refusal, inability or failure on the part of the Company to comply with any of the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to or does not 39

perform all of its obligations under this Agreement, the Company will not be liable to the Underwriter for damages on account of loss of anticipated profits arising out of the transactions covered by this Agreement, but the Company will remain liable to the extent provided in Sections 5(j), 7, 8 and 9 of this Agreement. 11. Information Furnished by the Underwriter to the Company. It is hereby acknowledged and agreed by the parties hereto that for the purposes of this Agreement, including, without limitation, Sections 4(f), 7(a), 7(b) and 8 hereof, the only information given by the Underwriter to the Company for use in the Prospectus are the statements set forth in the last sentence of the_____ paragraph on the cover page, the statement appearing in the ____ paragraph on page __ with respect to stabilizing the market price of Shares, the information in the __ paragraph on page __ with respect to concessions and reallowances, and the information in the ___ paragraph on page ___ with respect to the determination of the public offering price, as such information appears in any Preliminary Prospectus and in the Prospectus. 12.

SECOND: The address, including street, number, city and county of the registered office of the Corporation in the State of Delaware is 229 South State Street, City of Dover, County of Kent; and the name of the registered agent of the Corporation in the State of Delaware at such address is the Corporation Service Company. THIRD: The nature of the business and the purposes to be conducted and promoted by the Corporation shall be to conduct any lawful business, to promote any lawful purpose, and to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of the State of Delaware. FOURTH: The total number of all classes of shares of stock which the corporation shall have authority to issue is twenty-five million (25,000,000) shares, consisting of ten million (10,000,000) shares of Preferred Stock with a par value of $.01 per share, and fifteen million (15,000,000) shares of Common Stock with a par value of $.01 per share, amounting in the aggregate to two hundred and fifty thousand dollars ($250,000). The designation and powers, rights and preferences, and the qualifications, limitation, or restrictions with respect to each class or series of such class of the stock of the Corporation shall be as determined by resolution of the Board of Directors from time to time. FIFTH: The corporation is to have perpetual existence. SIXTH: For the management of the business and for the conduct of the affairs of the Corporation, and in further definition, limitation, and regulation of the powers of the Corporation and of its directors and of its stockholders or any class thereof, as the case may be, it is further provided: 1. The management of the business and the conduct of the affairs of the Corporation shall be vested in its Board of Directors. The number of directors shall be determined by affirmative vote of a majority of the Board of Directors, but shall be not less than three (3).

2. The directors shall be divided into three classes, designated Class I, Class II and Class III. Each class shall consist, as nearly as may be possible, of one-third of the total number of directors constituting the entire Board of Directors. The term of the initial Class I directors shall terminate on the date of the 2001 annual meeting of stockholders; the term of the initial Class II directors shall terminate on the date of the 2002 annual meeting of stockholders and the term of the Class III directors shall terminate on the date of the 2003 annual meeting of stockholders. At each annual meeting of stockholders beginning in 2001, successors to the class of directors whose term expires at that annual meeting shall be elected for a three-year term. If the number of directors is changed, any increase or decrease in directorships shall be apportioned among the classes so as to maintain the number of directors in each class as nearly equal as possible, and any additional directors of any class elected to fill a vacancy resulting from an increase in such class shall hold office for a term that shall coincide with the remaining term of that class, but in no case will a decrease in the number of directors shorten the term of any incumbent director.

A majority of total directors shall constitute a quorum for the transaction of business.

Any director elected to fill a vacancy shall hold office for a term that shall coincide with the remaining term of that class. 3. Notwithstanding the foregoing, whenever the holders of any one or more classes or series of Preferred Stock issued by the Corporation shall have the right, voting separately by class or series, to elect directors at an annual or special meeting of stockholders, the election, term of office, filling of vacancies and features of such directorships shall be governed by the terms of this Certificate of Incorporation or the resolution or resolutions adopted by the Board of Directors applicable thereto, and such directors so elected shall not be divided into classes pursuant to this Article unless expressly provided by such terms. 4. Subject to the rights, if any, of the holders of shares of Preferred Stock then outstanding, any or all of the directors of the Corporation may be removed from office at any time, with or without cause, by affirmative vote of two-thirds of the directors then in office or for cause only by the affirmative vote of the holders of at least eighty percent (80%) of the outstanding stock of the Corporation then entitled to vote generally for the election of directors, considered for purposes of this Article as one class. 5. The power to adopt, amend, or repeal the By-Laws of the Corporation may be exercised by the affirmative vote of a majority of the Board of Directors of the Corporation. In addition, the By-Laws may be amended by the stockholders, except that Articles II, III, IV, V, VI and IX of the By-Laws shall not be altered, amended or repealed by the stockholders, and no provision inconsistent therewith shall be adopted by the stockholders, without the affirmative vote of at least eighty percent (80%) of the outstanding stock of the Corporation entitled to vote thereon. 6. The Board of Directors shall have the power, when considering a tender offer or merger or acquisition proposal, to take into account any and all factors that the Board of Directors determines to be relevant, including, but not limited to the following: (a) the interests of the Corporation's stockholders, including the possibility that these interests might be best served by the continued independence of the Corporation; -2-

(b) whether the proposed transaction might violate federal or state laws; (c) not only the consideration being offered in the proposed transaction, in relation to the then current market price for the outstanding capital stock of the Corporation, but also to the market price for the capital stock of the Corporation over a period of years, the estimated price that might be achieved in a negotiated sale of the Corporation as a whole or in part or through orderly liquidation, the premiums over market price for the securities of other corporations in similar transactions, current political, economic and other factors bearing on securities prices and the Corporation's financial condition and future prospects; and (d) the social, legal and economic effects upon employees, suppliers, customers, creditors and others having similar relationships with the Corporation, upon the communities in which the Corporation conducts its business and upon the economy of the state, region and nation. 7.

SEVENTH: No person serving as a director of the Corporation shall be personally liable to the Corporation or its stockholders for breach of his or her fiduciary duty as a director; provided, however, that the foregoing shall not eliminate or limit the liability of a director of the Corporation (i) for any breach of the director's duty of loyalty to the Corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the Delaware General Corporation Law, or (iv) for any transaction from which the director derived an improper personal benefit. EIGHTH: The Corporation shall, to the fullest extent permitted by Section 145 of the General Corporation Law of the State of Delaware, as the same may be amended and supplemented, indemnify (and advance expenses to) any and all persons who it shall have power to indemnify (and advance expenses to) under said section from and against any and all of the expenses, liabilities, or other matters referred to in or covered by said section, and the indemnification and advancement provided for herein shall not be deemed exclusive of any other rights to which those indemnified may be entitled under any By-law, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director, officer, employee, or agent and shall inure to the benefit of the heirs, executors, and administrators of such a person. -3-

NINTH: Annual meetings of the stockholders shall be held on the date set in the Corporation's By-Laws. Any stockholder who desires to present a proposal or other matter or to nominate any person for election to the Board of Directors at an annual meeting of stockholders shall be entitled to present such proposal, matter or nomination at the annual meeting only if such stockholder notifies the Corporation, in writing, signed by the stockholder or stockholders submitting the notice, addressed to the Secretary of the Corporation, describing in detail the proposal or other matter to be presented and, in the case of nomination of a director, specifically identifying the person or persons such stockholder is nominating, sent by and delivery, overnight delivery or certified mail, return receipt requested, and such notice is received by the Secretary or President of the Corporation not less than one hundred and twenty (120) calendar days before the date of the Corporation's proxy statement released to the stockholders in connection with the previous year's annual meeting.

TENTH: From time to time any of the provisions of this certificate of incorporation may be amended, altered, or repealed, and other provisions authorized by the laws of the State of Delaware at the time in force may be added or inserted in the manner and at the time prescribed by said laws, and all rights at any time conferred upon the stockholders of the Corporation by this certificate of incorporation are granted subject to the provision of this Article TENTH, except that Articles SIXTH, SEVENTH, EIGHTH, NINTH and this Article TENTH shall not be altered, amended or repealed and no provision inconsistent therewith shall be adopted without the affirmative vote of the holders of at least eighty percent (80%) of the voting power of all the stock of the Corporation entitled to vote generally in the election of directors, voting together as a single class.

NOW, THEREFORE, in consideration of the premises, the payment by the Underwriter to the Company of ONE HUNDRED DOLLARS ($100.00), the agreements herein set forth and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 1. Grant. ------ The Underwriter and/or the Designees are hereby granted the right to purchase, at any time from ____________, 2000 until 5:00 P.M., New York time, on _______, 2005 (the "Warrant Exercise Term"), up to 200,000 fully-paid and non-assessable Shares at an initial exercise price (subject to adjustment as provided in Article 8 hereof) of $9.90 per Share. 2. Warrant Certificates. --------------------- The warrant certificates delivered and to be delivered pursuant to this Agreement (the "Warrant Certificates") shall be in the form set forth in Exhibit A attached hereto and made a part hereof, with such appropriate insertions, omissions, substitutions and other variations as required or permitted by this Agreement. 2

3. Exercise of Warrant. ---------------------- 3.1. Cash Exercise. The Warrants initially are exercisable at a price of $9.90 per Share, payable in cash or by check to the order of the Company, or any combination thereof, subject to adjustment as provided in Article 8 hereof. Upon surrender of the Warrant Certificate with the annexed Form of Election to Purchase duly executed, together with payment of the Exercise Price (as hereinafter defined) for the Shares purchased, at the Company's principal offices in New York (currently located at 1100 Summer Street, Stamford, Connecticut 06905) the registered holder of a Warrant Certificate ("Holder" or "Holders") shall be entitled to receive a certificate or certificates for the Shares so purchased. The purchase rights represented by each Warrant Certificate are exercisable at the option of the Holder thereof, in whole or in part (but not as to fractional Shares). In the case of the purchase of less than all the Shares purchasable under any Warrant Certificate, the Company shall cancel said Warrant Certificate upon the surrender thereof and shall execute and deliver a new Warrant Certificate of like tenor for the balance of the Shares purchasable thereunder. 3.2. Cashless Exercise. At any time during the Warrant Exercise Term, the Holder may, at the Holder's option, exchange, in whole or in 3

part, the Warrants represented by such Holder's Warrant Certificate (a "Warrant Exchange"), into the number of Shares determined in accordance with this Section 3.2, by surrendering such Warrant Certificate at the principal office of the Company or at the office of its transfer agent, accompanied by a notice stating such Holder's intent to effect such exchange, the number of Warrants to be so exchanged and the date on which the Holder requests that such Warrant Exchange occur (the "Notice of Exchange"). The Warrant Exchange shall take place on the date specified in the Notice of Exchange or, if later, the date the Notice of Exchange is received by the Company (the "Exchange Date"). Certificates for the Shares issuable upon such Warrant Exchange and, if applicable, a new Warrant Certificate of like tenor representing the Warrants which were subject to the surrendered Warrant Certificate and not included in the Warrant Exchange, shall be issued as of the Exchange Date and delivered to the Holder within three (3) days following the Exchange Date. In connection with any Warrant Exchange, the Holder shall be entitled to subscribe for and acquire (i) the number of Shares (rounded to the next highest integer) which would, but for the Warrant Exchange, then be issuable pursuant to the provision of Section 3.1 above upon the exercise of the Warrants specified by the Holder in its Notice of Exchange (the 4

"Total Number") less (ii) the number of Shares equal to the quotient obtained by dividing (a) the product of the Total Number and the existing Exercise Price (as hereinafter defined) by (b) the Market Price (as hereinafter defined) of a Public Share on the day preceding the Warrant Exchange. "Market Price" at any date shall be deemed to be the last reported sale price, or, in case no such reported sales takes place on such day, the average of the last reported sale prices for the last three (3) trading days, in either case as officially reported by the principal securities exchange on which the Common Stock is listed or admitted to trading or as reported in the NASDAQ National Market System, or, if the Common Stock is not listed or admitted to trading on any national securities exchange or quoted on the NASDAQ National Market System, the closing bid price as furnished by (i) the National Association of Securities Dealers, Inc. through Nasdaq or (ii) a similar organization if Nasdaq is no longer reporting such information. 4. Issuance of Certificates. ------------------------- Upon the exercise of the Warrants, the issuance of certificates for the Shares purchased shall be made forthwith (and in any event within three (3) business days thereafter) without charge to the Holder thereof including, without limitation, any tax which may be payable in respect of the 5

issuance thereof, and such certificates shall (subject to the provisions of Article 5 hereof) be issued in the name of, or in such names as may be directed by, the Holder thereof; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any such certificates in a name other than that of the Holder and the Company shall not be required to issue or deliver such certificates unless or until the person or persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. The Warrant Certificates and the certificates representing the Shares shall be executed on behalf of the Company by the manual or facsimile signature of the present or any future Chairman or Vice Chairman of the Board of Directors, Chief Executive Officer or President or Vice President of the Company under its corporate seal reproduced thereon, attested to by the manual or facsimile signature of the present or any future Secretary or Assistant Secretary of the Company. Warrant Certificates shall be dated the date of execution by the Company upon initial issuance, division, exchange, substitution or transfer. 6

Upon exercise, in part or in whole, of the Warrants, certificates representing the Shares shall bear a legend substantially similar to the following: "The securities represented by this certificate have not been registered for purposes of public distribution under the Securities Act of 1933, as amended (the "Act"), and may not be offered or sold except (i) pursuant to an effective registration statement under the Act, (ii) to the extent applicable, pursuant to Rule 144 under the Act (or any similar rule under such Act relating to the disposition of securities), or (iii) upon the delivery by the holder to the Company of an opinion of counsel, reasonably satisfactory to counsel to the Company, stating that an exemption from registration under such Act is available." 5. Restriction on Transfer of Warrants. ------------------------------------ The Holder of a Warrant Certificate, by the Holder's acceptance thereof, covenants and agrees that the Warrants are being acquired as an investment and not with a view to the distribution thereof, and that the Warrants may not be sold, transferred, assigned, hypothecated or otherwise disposed of, in whole or in part, for a period of one (1) year from the date hereof, except to the Designees. 6. Price. ------ 6.1. Initial and Adjusted Exercise Price. The initial exercise price of each Warrant shall be $9.90 per Share. The adjusted exercise price per Share shall be the price which shall result from time to time from any and all adjustments of the initial exercise price per Share in accordance with the provisions of Article 8 hereof. 7

6.2. Exercise Price. The term "Exercise Price" herein shall mean the initial exercise price or the adjusted exercise price, depending upon the context. 7. Registration Rights. -------------------- 7.1. Registration Under the Securities Act of 1933. None of the Warrants or Shares have been registered for purposes of public distribution under the Securities Act of 1933, as amended (the "Act"). 7.2. Registrable Securities. As used herein the term "Registrable Security" means each of the Warrants, the Shares and any shares of Common Stock issued upon any stock split or stock dividend in respect of such Shares; provided, however, that with respect to any particular Registrable Security, such security shall cease to be a Registrable Security when, as of the date of determination, (i) it has been effectively registered under the Act and disposed of pursuant thereto, (ii) registration under the Act is no longer required for the subsequent public distribution of such security or (iii) it has ceased to be outstanding. The term "Registrable Securities" means any and/or all of the securities falling within the foregoing definition of a "Registrable Security." In the event of any merger, reorganization, consolidation, 8

recapitalization or other change in corporate structure affecting the Common Stock, such adjustment shall be made in the definition of "Registrable Security" as is appropriate in order to prevent any dilution or enlargement of the rights granted pursuant to this Article 7. 7.3. Piggyback Registration. If, at any time following the effective date of the Public Offering, the Company proposes to prepare and file one or more post-effective amendments to the registration statement filed in connection with the Public Offering or any new registration statement or post-effective amendments thereto covering equity or debt securities of the Company, or any such securities of the Company held by its stockholders (in any such case, other than in connection with a merger, acquisition or pursuant to Form S-8 or successor form), (for purposes of this Article 7, collectively, the "Registration Statement"), it will give written notice of its intention to do so by registered mail ("Notice"), at least thirty (30) business days prior to the filing of each such Registration Statement, to all holders of the Registrable Securities. Upon the written request of such a holder (a "Requesting Holder"), made within twenty (20) business days after receipt of the Notice, that the 9

Company include any of the Requesting Holder's Registrable Securities in the proposed Registration Statement, the Company shall, as to each such Requesting Holder, use its best efforts to effect the registration under the Act of the Registrable Securities which it has been so requested to register ("Piggyback Registration"), at the Company's sole cost and expense and at no cost or expense to the Requesting Holders (except as provided in Section 7.5(b) hereof). 7.4. Demand Registration. ------------------- (a) At any time during the Warrant Exercise Term, any "Majority Holder" (as such term is defined in Section 7.4(c) below) of the Registrable Securities shall have the right (which right is in addition to the piggyback registration rights provided for under Section 7.3 hereof), exercisable by written notice to the Company (the "Demand Registration Request"), to have the Company prepare and file with the Securities and Exchange Commission (the "Commission"), on one occasion, at the sole expense of the Company (except as provided in Section 7.5(b) hereof), a Registration Statement and such other documents, including a prospectus, as may be necessary (in the opinion of both counsel for the Company and counsel for such Majority Holder), in order to comply with the provisions of the Act, so as to permit a public offering and sale of the Registrable Securities by the holders thereof. The 10

Company shall use its best efforts to cause the Registration Statement to become effective under the Act, so as to permit a public offering and sale of the Registrable Securities by the holders thereof. Once effective, the Company will use its best efforts to maintain the effectiveness of the Registration Statement until the earlier of (i) the date that all of the Registrable Securities have been sold or (ii) the date that the holders of the Registrable Securities receive an opinion of counsel to the Company that all of the Registrable Securities may be freely traded (without limitation or restriction as to quantity or timing and without registration under the Act) under Rule 144(k) promulgated under the Act or otherwise. (b) The Company covenants and agrees to give written notice of any Demand Registration Request to all holders of the Registrable Securities within ten (10) business days from the date of the Company's receipt of any such Demand Registration Request. After receiving notice from the Company as provided in this Section 7.4(b), holders of Registrable Securities may request the Company to include their Registrable Securities in the Registration Statement to be filed pursuant to Section 7.4(a) hereof by notifying the Company of their decision to have such securities included within ten (10) days of their receipt of the Company's notice. 11

(c) The term "Majority Holder" as used in Section 7.4 hereof shall mean any holder or any combination of holders of Registrable Securities, if included in such holders' Registrable Securities are that aggregate number of shares of Common Stock (including Shares already issued and Shares issuable pursuant to the exercise of outstanding Warrants) as would constitute a majority of the aggregate number of Shares (including Shares already issued and Shares issuable pursuant to the exercise of outstanding Warrants) included in all the Registrable Securities. 7.5. Covenants of the Company With Respect to Registration. ------------------------------------------------------ The Company covenants and agrees as follows: (a) In connection with any registration under Section 7.4 hereof, the Company shall file the Registration Statement as expeditiously as possible, but in any event no later than twenty (20) days following receipt of any demand therefor, shall use its best efforts to have any such Registration Statement declared effective at the earliest possible time, and shall furnish each holder of Registrable Securities such number of prospectuses as shall reasonably be requested. (b) The Company shall pay all costs, fees and expenses (other than underwriting fees, discounts and nonaccountable expense allowance applicable to the Registrable Securities and the fees and expenses of counsel retained by the holders of Registrable Securities) in connection with all 12

Registration Statements filed pursuant to Sections 7.3 and 7.4(a) hereof including, without limitation, the Company's legal and accounting fees, printing expenses, and blue sky fees and expenses. (c) The Company will take all necessary action which may be required in qualifying or registering the Registrable Securities included in the Registration Statement for offering and sale under the securities or blue sky laws of such states as are reasonably requested by the holders of such securities. (d) The Company shall indemnify any holder of the Registrable Securities to be sold pursuant to any Registration Statement and any underwriter or person deemed to be an underwriter under the Act and each person, if any, who controls such holder or underwriter or person deemed to be an underwriter within the meaning of Section 15 of the Act or Section 20(a) of the Securities Exchange Act of 1934, as amended ("Exchange Act"), against all loss, claim, damage, expense or liability (including all expenses reasonably incurred in investigating, preparing or defending against any claim whatsoever) to which any of them may become subject under the Act, the Exchange Act or otherwise, arising 13

from such Registration Statement to the same extent and with the same effect as the provisions pursuant to which the Company has agreed to indemnify the Underwriter as set forth in Section 7 of the Underwriting Agreement and to provide for just and equitable contribution as set forth in Section 8 of the Underwriting Agreement. (e) Any holder of Registrable Securities to be sold pursuant to a Registration Statement, and such holder's successors and assigns, shall severally, and not jointly, indemnify, the Company, its officers and directors and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, against all loss, claim, damage or expense or liability (including all expenses reasonably incurred in investigating, preparing or defending against any claim whatsoever) to which they may become subject under the Act, the Exchange Act or otherwise, arising from information furnished by or on behalf of such holder, or such holder's successors or assigns, for specific inclusion in such Registration Statement to the same extent and with the same effect as the provisions pursuant to which the Underwriter has agreed to indemnify the Company as set forth in Section 7 of the Underwriting Agreement and to provide for just and equitable contribution as set forth in Section 8 of the Underwriting Agreement. 14

(f) Nothing contained in this Agreement shall be construed as requiring any Holder to exercise the Warrants held by such Holder prior to the initial filing of any Registration Statement or the effectiveness thereof. (g) If the Company shall fail to comply with the provisions of this Article 7, the Company shall, in addition to any other equitable or other relief available to the holders of Registrable Securities, be liable for any or all incidental, special and consequential damages sustained by the holders of Registrable Securities, requesting registration of their Registrable Securities. (h) The Company shall promptly deliver copies of all correspondence between the Commission and the Company, its counsel or auditors and all memoranda relating to discussions with the Commission or its staff with respect to the Registration Statement to each holder of Registrable Securities included for such registration in such Registration Statement pursuant to Section 7.3 hereof or Section 7.4 hereof requesting such correspondence and memoranda and to the managing underwriter, if any, of the offering in connection with which such holder's Registrable Securities are being registered and shall 15

permit each holder of Registrable Securities and such underwriter to do such reasonable investigation, upon reasonable advance notice, with respect to information contained in or omitted from the Registration Statement as it deems reasonably necessary to comply with applicable securities laws or rules of the National Association of Securities Dealers, Inc. Such investigation shall include access to books, records and properties and opportunities to discuss the business of the Company with its officers and independent auditors, all to such reasonable extent and at such reasonable times and as often as any such holder of Registrable Securities or underwriter shall reasonably request. 8. Adjustments of Exercise Price and Number of Shares. --------------------------------------------------- 8.1. Computation of Adjusted Price. In case the Company shall at any time after the date hereof pay a dividend in shares of Common Stock or make a distribution in shares of Common Stock, then upon such dividend or distribution the Exercise Price in effect immediately prior to such dividend or distribution shall forthwith be reduced to a price determined by dividing: (a) an amount equal to the total number of shares of Common Stock outstanding immediately prior to such dividend or distribution multiplied by the Exercise Price in effect immediately prior to such dividend or distribution, by 16

(b) the total number of shares of Common Stock outstanding immediately after such issuance or sale. For the purposes of any computation to be made in accordance with the provisions of this Section 8.1, the Common Stock issuable by way of dividend or other distribution on any stock of the Company shall be deemed to have been issued immediately after the opening of business on the date following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution. 8.2. Subdivision and Combination. In case the Company shall at any time subdivide or combine the outstanding shares of Common Stock, the Exercise Price shall forthwith be proportionately decreased in the case of subdivision or increased in the case of combination. 8.3. Adjustment in Number of Shares. Upon each adjustment of the Exercise Price pursuant to the provisions of this Article 8, the number of Shares issuable upon the exercise of each Warrant shall be adjusted to the nearest full number by multiplying a number equal to the Exercise Price in effect immediately prior to such adjustment by the number of Shares issuable upon exercise of the Warrants immediately prior to such adjustment and dividing the product so obtained by the adjusted Exercise Price. 17

8.4. Reclassification, Consolidation, Merger, etc. In case of any reclassification or change of the outstanding shares of Common Stock (other than a change in par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), or in the case of any consolidation of the Company with, or merger of the Company into, another corporation (other than a consolidation or merger in which the Company is the surviving corporation and which does not result in any reclassification or change of the outstanding shares of Common Stock, except a change as a result of a subdivision or combination of such shares or a change in par value, as aforesaid), or in the case of a sale or conveyance to another corporation of the property of the Company as an entirety, the Holders shall thereafter have the right to purchase the kind and number of shares of stock and other securities and property receivable upon such reclassification, change, consolidation, merger, sale or conveyance as if the Holders were the owners of the shares of Common Stock underlying the Warrants immediately prior to any such events at a price equal to the product of (x) the number of shares of Common Stock issuable upon exercise of the Holder's Warrants and (y) the Exercise Price in effect immediately prior to the record date for such reclassification, change, consolidation, merger, sale or conveyance as if such Holders had exercised the Warrants. 18

8.5. Determination of Outstanding Shares of Common Stock. The number of shares of Common Stock at any one time outstanding shall include the aggregate number of shares of Common Stock issued and the aggregate number of shares of Common Stock issuable upon the exercise of options, rights, warrants and upon the conversion or exchange of convertible or exchangeable securities. 8.6. Dividends and Other Distributions with Respect to Outstanding Securities. In the event that the Company shall at any time prior to the exercise of all Warrants make any distribution of its assets to holders of its Common Stock as a liquidating or a partial liquidating dividend, then the holder of Warrants who exercises its Warrants after the record date for the determination of those holders of Common Stock entitled to such distribution of assets as a liquidating or partial liquidating dividend shall be entitled to receive for the Warrant Price per Warrant, in addition to each share of Common Stock, the amount of such distribution (or, at the option of the Company, a sum equal to the value of any such assets at the time of such distribution as 19

determined by the Board of Directors of the Company in good faith) which would have been payable to such holder had he been the holder of record of the Common Stock receivable upon exercise of his Warrant on the record date for the determination of those entitled to such distribution. At the time of any such dividend or distribution, the Company shall make appropriate reserves to ensure the timely performance of the provisions of this Subsection 8.6. 8.7. Subscription Rights for Shares of Common Stock or Other Securities. In the case that the Company or an affiliate of the Company shall at any time after the date hereof and prior to the exercise of all the Warrants issue any rights, warrants or options to subscribe for shares of Common Stock or any other securities of the Company or of such affiliate to all the stockholders of the Company, the Holders of unexercised Warrants on the record date set by the Company or such affiliate in connection with such issuance of rights, warrants or options shall be entitled, in addition to the shares of Common Stock or other securities receivable upon the exercise of the Warrants, to receive such rights, warrants or options that such Holders would have been entitled to receive had they been, on such record date, the holders of record of the number of whole shares of Common Stock then issuable upon exercise of their outstanding Warrants (assuming for purposes of this Section 8.7), that the exercise of the Warrants is permissible immediately upon issuance). 20

9. Exchange and Replacement of Warrant Certificates. ------------------------------------------------- Each Warrant Certificate is exchangeable without expense, upon the surrender thereof by the registered Holder at the principal executive office of the Company, for a new Warrant Certificate of like tenor and date representing in the aggregate the right to purchase the same number of securities in such denominations as shall be designated by the Holder thereof at the time of such surrender. Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of any Warrant Certificate, and, in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it, and reimbursement to the Company of all reasonable expenses incidental thereto, and upon surrender and cancellation of the Warrant Certificate, if mutilated, the Company will make and deliver a new Warrant Certificate of like tenor, in lieu thereof. 10. Elimination of Fractional Interests. The Company shall not be required to issue certificates representing fractions of Shares, nor shall it be required to issue scrip or pay cash in lieu of fractional interests, it being the intent of the parties that all fractional interests shall be eliminated by rounding any fraction up to the nearest whole number of Shares. 21

11. Reservation and Listing of Securities. -------------------------------------- The Company shall at all times reserve and keep available out of its authorized shares of Common Stock, solely for the purpose of issuance upon the exercise of the Warrants, such number of shares of Common Stock as shall be issuable upon the exercise thereof. The Company covenants and agrees that, upon exercise of the Warrants and payment of the Exercise Price therefor, all Shares issuable upon such exercise shall be duly and validly issued, fully paid, non-assessable and not subject to the preemptive rights of any stockholder. As long as the Warrants shall be outstanding, the Company shall use its best efforts to cause all shares of Common Stock issuable upon the exercise of the Warrants to be listed on or quoted by Nasdaq or listed on such national securities exchange, in the event the Common Stock is listed on a national securities exchange. 12. Notices to Warrant Holders. --------------------------- Nothing contained in this Agreement shall be construed as conferring upon the Holder or Holders the right to vote or to consent or to receive notice as a stockholder in respect of any meetings of stockholders for the election of directors or any other matter, or as having any rights 22

whatsoever as a stockholder of the Company. If, however, at any time prior to the expiration of the Warrants and their exercise, any of the following events shall occur: (a) the Company shall take a record of the holders of its shares of Common Stock for the purpose of entitling them to receive a dividend or distribution payable otherwise than in cash, or a cash dividend or distribution payable otherwise than out of current or retained earnings, as indicated by the accounting treatment of such dividend or distribution on the books of the Company; or (b) the Company shall offer to all the holders of its Common Stock any additional shares of capital stock of the Company or securities convertible into or exchangeable for shares of capital stock of the Company, or any option, right or warrant to subscribe therefor; or (c) a dissolution, liquidation or winding up of the Company (other than in connection with a consolidation or merger) or a sale of all or substantially all of its property, assets and business as an entirety shall be proposed; or 23

(d) reclassification or change of the outstanding shares of Common Stock (other than a change in par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), consolidation of the Company with, or merger of the Company into, another corporation (other than a consolidation or merger in which the Company is the surviving corporation and which does not result in any reclassification or change of the outstanding shares of Common Stock, except a change as a result of a subdivision or combination of such shares or a change in par value, as aforesaid), or a sale or conveyance to another corporation of the property of the Company as an entirety is proposed; or (e) The Company or an affiliate of the Company shall propose to issue any rights to subscribe for shares of Common Stock or any other securities of the Company or of such affiliate to all the shareholders of the Company; then, in any one or more of said events, the Company shall give written notice to the Holder or Holders of such event at least fifteen (15) days prior to the date fixed as a record date or the date of closing the transfer books for the determination of the stockholders entitled to such dividend, distribution, 24

convertible or exchangeable securities or subscription rights, options or warrants, or entitled to vote on such proposed dissolution, liquidation, winding up or sale. Such notice shall specify such record date or the date of closing the transfer books, as the case may be. Failure to give such notice or any defect therein shall not affect the validity of any action taken in connection with the declaration or payment of any such dividend or distribution, or the issuance of any convertible or exchangeable securities or subscription rights, options or warrants, or any proposed dissolution, liquidation, winding up or sale. 13. Notices. -------- All notices, requests, consents and other communications hereunder shall be in writing and shall be deemed to have been duly made when delivered, or mailed by registered or certified mail, return receipt requested: (a) If to a registered Holder of the Warrants, to the address of such Holder as shown on the books of the Company; or (b) If to the Company, to the address set forth in Section 3 of this Agreement or to such other address as the Company may designate by notice to the Holders. 25

14. Supplements and Amendments. --------------------------- The Company and the Underwriter may from time to time supplement or amend this Agreement without the approval of any Holders of Warrant Certificates in order to cure any ambiguity, to correct or supplement any provision contained herein which may be defective or inconsistent with any provisions herein, or to make any other provisions in regard to matters or questions arising hereunder which the Company and the Underwriter may deem necessary or desirable and which the Company and the Underwriter deem not to adversely affect the interests of the Holders of Warrant Certificates. 15. Successors. ----------- All the covenants and provisions of this Agreement by or for the benefit of the Company and the Holders inure to the benefit of their respective successors and assigns hereunder. 16. Termination. ------------ This Agreement shall terminate at the close of business on __________, 2008. Notwithstanding the foregoing, this Agreement will terminate on any earlier date when all Warrants have been exercised and all the Shares issuable upon exercise of the Warrants have been resold to the public; provided, 26

however, that the provisions of Section 7 shall survive any termination pursuant to this Section 16 until the close of business on _________, 2011. 17. Governing Law. -------------- This Agreement and each Warrant Certificate issued hereunder shall be deemed to be a contract made under the laws of the State of New York and for all purposes shall be construed in accordance with the laws of said State. 18. Benefits of This Agreement. --------------------------- Nothing in this Agreement shall be construed to give to any person or corporation other than the Company and the Underwriter and any other registered holder or holders of the Warrant Certificates, Warrants or the Shares any legal or equitable right, remedy or claim under this Agreement; and this Agreement shall be for the sole and exclusive benefit of the Company and the Underwriter and any other holder or holders of the Warrant Certificates, Warrants or the Shares. 27

19. Counterparts. ------------- This Agreement may be executed in any number of counterparts and each of such counterparts shall for all purposes be deemed to be an original, and such counterparts shall together constitute but one and the same instrument.

(212) 838-8040 June 15, 2000 Delcath Systems, Inc. 1100 Summer Street Stamford, Connecticut 06905 Dear Sirs: We have acted as counsel to Delcath Systems, Inc., a Delaware corporation (the "Company") in connection with the preparation of a registration statement on Form SB-2 (the "Registration Statement") filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the "Act"), to register the offering by the Company of (i) 2,000,000 shares of common stock, par value $.01 per share (the "Common Stock"), (ii) an additional 300,000 shares of Common Stock if the over-allotment option is exercised in full, (iii) 200,000 warrants to purchase Common Stock (the "Warrants") (iv) 200,000 shares of Common Stock underlying the Warrants and (v) any additional shares of Common Stock issued pursuant to Rule 462(b) of the Act. In this regard, we have reviewed the Certificate of Incorporation of the Company, as amended, resolutions adopted by the Company's Board of Directors, the Registration Statement, the other exhibits to the Registration Statement and such other records, documents, statutes and decisions as we have deemed relevant in rendering this opinion. Based upon the foregoing, we are of the opinion that each share of Common Stock being offered, including shares which may be issued upon the exercise of the Warrants in accordance with their terms, has been duly and validly authorized for issuance and when issued as contemplated by the Registration Statement will be legally issued, fully paid and non-assessable. We hereby consent to the use of this opinion as Exhibit 5.1 to the Registration Statement and to all references to us in the Registration Statement. In giving such opinion, we do not thereby admit that we are acting within the category of persons whose consent is required under Section 7 of the Act or the rules or regulations of the Securities and Exchange Commission thereunder. Very truly yours, /s/ Morse, Zelnick, Rose & Lander, LLP ------------------------------------ MORSE, ZELNICK, ROSE & LANDER, LLP

1992 INCENTIVE STOCK OPTION PLAN OF DELCATH SYSTEMS, INC. 1. Purpose of Plan The purpose of this 1992 Incentive Stock Option Plan (the "Plan") is to further the growth and development of Delcath Systems, Inc. (the "Company") and any direct and indirect subsidiaries thereof (collectively, "Subsidiaries", and each, singly, a "Subsidiary") by encouraging selected employees who contribute and are expected to contribute materially to the Company's success to obtain a proprietary interest in the Company through the ownership of stock, thereby providing such persons with an added incentive to promote the best interests of the Company and affording the Company a means of attracting to its service persons of outstanding ability. 2. Incentive Stock Options; Stock Subject to the Plan. An aggregate of 160,000 shares of the Company's Common Stock, $.01 par value ("Common Stock"), subject, however, to adjustment or change pursuant to paragraph 12 hereof, shall be reserved for issuance upon the exercise of incentive stock options within the meaning of Section 422 (b) of the Internal Revenue Code of 1986, as amended (the "Code") which may be granted from time to time in accordance with the Plan ("Options"). Such shares may be, in whole or in part, as the Stock Option Committee (the "Committee") shall from time to time determine, authorized but unissued shares or issued shares which have been reacquired by the Company. If, for any reason, an Option shall lapse, expire or terminate without having been exercised in full, the unpurchased shares covered thereby shall again be available for purposes of the Plan. 3. Administration. (a) The Board of Directors shall appoint the Committee from among its members. Such Committee shall be composed of two or more Directors who shall be "disinterested persons" as defined by Regulation 240.16b-3 under the Securities Exchange Act of 1934, as amended. Such Committee shall have and may exercise any and all of the powers relating to the administration of the Plan and the grant of Options there under as are set forth in subparagraph 3(b) hereof. The Board of Directors shall have the power at any time to fill vacancies in, to change the membership of, or to discharge such Committee. The Committee shall select one of its members as its chairman and shall hold its meetings at such times and at such places as it shall deem advisable. A majority of such Committee shall constitute a quorum, and such majority shall determine its action. Any action may be taken without a meeting by written consent of all the members of the Committee. The Committee shall keep minutes of its proceedings and shall report the same to the Board of Directors at the meeting next succeeding. (b) The Committee shall administer the Plan and, subject to the provisions of the Plan, shall have sole authority in its discretion to determine the persons to whom, and the time or times at which. Options shall be granted, and the number of shares to be subject to each such Option. In making such determinations, the Committee may take into account the nature of the services rendered by such persons, their present and potential contributions to the Company's success and such other factors as the Committee in its sole discretion

may deem relevant. Subject to the express provisions of the Plan, the Committee shall also have the authority to interpret the Plan, to prescribe, amend and-rescind rules and regulations relating thereto, to determine the terms and provisions of the respective Option Agreements, which shall be substantially in the form attached hereto as Exhibit A, and to make all other determinations necessary or advisable for the administration of the Plan, all of which determinations shall be conclusive and not subject to review. 4. Eligibility for Receipt of Options. Options hereunder may be granted only to employees (including officers) of the Company and/or any of its Subsidiaries. The aggregate Fair Market Value (as defined in paragraph 5 of the Plan), determined as of the time the Option is granted, of the shares of the Company's Common Stock purchasable there under exercisable for the first time by an employee during any calendar year may not exceed $100,000. Options may not be granted to any person who, at the time the Option is granted, owns (or is considered as owning within the meaning of Section 425 (d) of the Code) stock possessing more than 10% of the total combined voting powers of all classes of stock of the Company or any Subsidiary (a "10% Owner"), unless at the time the Option is granted to a 10% Owner, the option price is at least 110% of the fair market value of the Common Stock subject thereto and such Option by its terms is not exercisable subsequent to five years from the date of grant. Nothing herein contained shall prohibit the Company from granting Options hereunder to any holder of any other incentive or non-incentive stock options of the Company, if any, provided the prospective recipient of Options hereunder is otherwise eligible to receive such Options pursuant to the terms of this Plan, and each type of option is clearly designated. 5. Option Price. The purchase price of the shares of Common Stock under each Option shall be determined by the Committee, which determination shall be conclusive and not subject to review, but in no event shall the purchase price of the shares of Common Stock under any Option be less than 100% of the fair market value of the Common Stock on the date of grant (110% of fair market value in the case of Options granted to a 10% Owner). In determining the fair market value of the Common Stock as of a specified date (the "Fair Market Value"), the Committee shall consider, if the Common Stock is: (a) publicly traded and listed on the New York Stock Exchange or another national securities exchange, the closing price of the Common Stock on the business day immediately preceding the date as of which the Fair Market Value is being determined, or on the next preceding date on which such Common Stock is traded if no Common Stock was traded on such immediately preceding business day, or, if the Common Stock is not so listed on a national securities exchange, but publicly traded, the representative closing bid price in the over-the-counter market as reported by NASDAQ or as quoted by the National Quotation Bureau or a recognized dealer in the Common Stock, on the date immediately preceding the date as of which the Fair Market Value is being determined, or on the next preceding date on which such Common Stock is traded if no Common Stock was traded on such immediately preceding business day; or (b) not publicly traded,

the fair market value as determined by the Committee in good faith based on such factors as it shall deem appropriate. The Committee may also consider such other factors as it shall deem appropriate. For purposes of the Plan, the date of grant of an Option shall be the date on which the Committee shall by resolution duly authorize such Option. 6. Term of Options. The term of each Option shall be such number of years as the Committee shall determine, subject to earlier termination as herein provided, and subject to the limitations set forth in paragraph 4 of this Plan with respect to grants to 10% owners, but in no event shall any Option be for a term of more than ten years from the date of grant. No Option may be exercised following termination thereof. 7. Exercise of Options. (a) (i) Vesting. No Option granted under the Plan shall be exercisable until such date or dates (inclusive of the date of grant and thereafter) as shall be determined by the Committee, but in no event until at least six months from the date of grant, with each Option to be so exercisable to the extent determined by the Committee. (ii) Minimum Exercise. An Option may not be exercised for fewer than ten shares at any one time (or the remaining shares then purchasable if less than ten) and may not be exercised fop fractional shares of the Company's Common Stock. (b) Except as provided in paragraphs 9, 10 and II hereof, no Option shall be exercisable unless the holder thereof shall have been an employee of the Company and/or a Subsidiary continuously from the date of grant to the date of exercise. (c) (i) The exercise of an Option shall be contingent upon receipt by the Company from the holder of such Option of: (1) cash, or a check to the order of the Company, for the full purchase price of the Option shares; (2) a written representation that at the time of such exercise it is the optionee's then present intention to acquire the Option shares for investment and not with a view to the distribution or resale thereof (unless a Registration Statement covering the shares purchasable upon exercise of the Options shall have been declared effective by the Securities and Exchange Commission, the Company being under no obligation to file such registration statement or process it to effectiveness); (3) a written acknowledgement by the Optionholder, in such form as may be determined by the Committee, that an investment in the Common Stock of the Company involves a high degree of risk, that the Optionholder has received a copy of the Company's financial statements for the most recently ended fiscal year for which such statement is available (which shall be provided annually by the Company to each Optionholder), and that the Optionholder has had the opportunity to ask questions of management concerning the Company prior to the exercise of the Option (the Company to provide such information as the Optionholder may reasonably request);

(4) such Stockholders' Agreement as the Company may require at the time of exercise of such Option (the "Stockholders' Agreement"), executed and delivered by the holder, the form of which the Company reserves the right to change at any time and from time to time, and which, among other things, may restrict the sale of the Option shares and other shares of capital stock of the Company subsequently acquired by the holder.

Such shares may be, in whole or in part, as the Stock Option Committee (the "Committee") shall from time to time determine, authorized but unissued shares or issued shares which have been reacquired by the Company. If, for any reason, an Option shall lapse, expire or terminate without having been exercised in full, the unpurchased shares covered thereby shall again be available for purposes of the Plan.

Administration (a) The Board of Directors shall appoint the Committee from among its members. Such Committee shall be composed of two or more Directors who shall be "disinterested persons" as defined under Rule 16b-3 under the Securities Exchange Act of 1934, as amended. Such Committee shall have and may exercise any and all of the powers relating to the administration of the Plan and the grant of Options thereunder as are set forth in subparagraph 3(b) hereof. The Board of Directors shall have the power at any time to fill vacancies in, to change the membership of, or to discharge such Committee. The Committee shall select one of its members as its chairman and shall hold its meetings at such times and at such places as it shall deem advisable. A majority of such Committee shall constitute a quorum, and such majority shall determine its action. Any action may be taken without a meeting by written consent of all the members of the Committee. The Committee shall keep minutes of its proceedings and shall report the same to the Board of Directors at the meeting next succeeding.

(b) The Committee shall administer the Plan and, subject to the provisions of the Plan, shall have sole authority in its discretion to determine the persons to whom, and the time or times at which, Options shall be granted, and the number of shares to be subject to each such Option. In making such determinations, the Committee may take into account the nature of the services rendered by such persons, their present and potential contributions to the Company's success and such other factors as the Committee in its sole discretion may deem relevant. Subject to the express provisions of the Plan, the Committee shall also have the authority to interpret the Plan, to prescribe, amend and-rescind rules and regulations relating thereto, to determine the terms and provisions of the respective Option Agreements, which shall be substantially in the form attached hereto as Exhibit A, and to make all other determinations necessary or advisable for the administration of the Plan, all of which determinations shall be conclusive and not subject to review. 4. Eligibility for Receipt of Options Options hereunder may be granted to any employees, directors, consultants, agents, independent contractors and other persons whom the Committee determines will contribute to the Company's success, provided that non-employees shall only be eligible to receive grants of Nonqualified Stock Options. The aggregate Fair Market Value (as defined in paragraph 5 of the Plan), determined as of the time the Option is granted, of the shares of the Company's Common Stock purchasable thereunder exercisable for the first time by an employee during any calendar year may not exceed $100,000.

Nothing herein contained shall prohibit the Company from granting Options hereunder to any holder of any other incentive or non-incentive stock options of the Company, if any, provided the prospective recipient of Options hereunder is otherwise eligible to receive such Options pursuant to the terms of this Plan, and each type of option is clearly designated. 5. Option Price The purchase price of the shares of Common Stock subject to an Option shall be determined by the Committee but shall be no less than 100% of the fair market value of a share of such Stock on the date such Option is granted; 2

provided, however, that (i) an Incentive Stock Option shall not be granted to any individual who, at the time of grant, owns stock possessing more than 10% of the total combined voting power or value of all classes of stock of the Company or parent of the Company, unless the option price per share is not less than 110% of the fair market value of a share of Common Stock on the date of grant, and (ii) in no event, based upon the facts known at the time of the grant, may a purchase price be established hereunder that would result in the disallowance of the Company's expense deduction pursuant to Section 162(m) of the Code. In determining the fair market value of the Common Stock as of a specified date (the "Fair Market Value"), the Committee shall consider, if the Common Stock is: (a) publicly traded and listed on the New York Stock Exchange or another national securities exchange, the closing price of the Common Stock on the business day immediately preceding the date as of which the Fair Market Value is being determined, or on the next preceding date on which such Common Stock is traded if no Common Stock was traded on such immediately preceding business day, or, if the Common Stock is not so listed on a national securities exchange, but publicly traded, the representative closing bid price in the over-the- counter market as reported by NASDAQ or as quoted by the National Quotation Bureau or a recognized dealer in the Common Stock, on the date immediately preceding the date as of which the Fair Market Value is being determined, or on the next preceding date on which such Common Stock is traded if no Common Stock was traded on such immediately preceding business day; or (b) not publicly traded, the fair market value as determined by the Committee in good faith based on such factors as it shall deem appropriate. The Committee may also consider such other factors as it shall deem appropriate. For purposes of the Plan, the date of grant of an Option shall be the date on which the Committee shall by resolution duly authorize such Option. 6. Term of Options The term of each Option shall be such number of years as the Committee shall determine, subject to earlier termination as herein provided for employee holders, and subject to the limitations set forth in paragraph 4 of this Plan with respect to grants to 10% owners, and for non-employee holders upon or following the occurrence of such events, all as the Committee may determine at the time of grant of an Option, which events may include, without limitation, the termination or cessation of the holder's performance of services to the Company or any subsidiary or the holder's death or disability. In no event shall any Option be for a term of more than ten years from the date of grant. Notwithstanding the foregoing, the term of options intended to qualify as Incentive Stock Options shall not exceed five (5) years from the date of granting thereof if such option is granted to any employee who at the time such option is granted owns more than ten percent (10%) of the total combined voting power of all classes of stock of the Company. No Option may be exercised following termination thereof. 7. Exercise of Options (a) (i) Vesting. No Option granted under the Plan shall be exercisable until such date or dates (inclusive of the date of grant and thereafter) as shall be determined by the Committee, but in no event until at least six months from the date of grant, with each Option to be so exercisable to the extent determined by the Committee. 3

(ii) Minimum Exercise. An Option may not be exercised for fewer than ten shares at any one time (or the remaining shares then purchasable if less than ten) and may not be exercised for fractional shares of the Company's Common Stock. (b) Except as provided in paragraphs 9, 10 and 11 hereof, no Option shall be exercisable unless the holder thereof shall have been an employee of the Company and/or a Subsidiary continuously from the date of grant to the date of exercise. (c) (i) The exercise of an Option shall be contingent upon receipt by the Company from the holder of such Option of: (1) cash, or a check to the order of the Company, for the full purchase price of the Option shares; (2) a written representation that at the time of such exercise it is the optionee's then present intention to acquire the Option shares for investment and not with a view to the distribution or resale thereof (unless a Registration Statement covering the shares purchasable upon exercise of the Options shall have been declared effective by the Securities and Exchange Commission, the Company being under no obligation to file such registration statement or process it to effectiveness); (3) a written acknowledgement by the Optionholder, in such form as may be determined by the Committee, that an investment in the Common Stock of the Company involves a high degree of risk, that the Optionholder has received a copy of the Company's financial statements for the most recently ended fiscal year for which such statement is available (which shall be provided annually by the Company to each Optionholder), and that the Optionholder has had the opportunity to ask questions of management concerning the Company prior to the exercise of the Option (the Company to provide such information as the Optionholder may reasonably request}; (4) such Stockholders' Agreement as the Company may require at the time of exercise of such Option (the "Stockholders' Agreement"), executed and delivered by the holder, the form of which the Company reserves the right to change at any time and from time to time, and which, among other things, may restrict the sale of the Option shares and other shares of capital stock of the Company subsequently acquired by the holder. Specifically, these restrictions may include, without limitation, that Venkol Ventures, L.P. and Venkol Ventures, Ltd. have a right of first refusal to purchase any or all shares of the Company's capital stock owned by the holder following a bona fide offer therefore by a third party. Additionally, in the event the two Venkol entities shall agree to sell all of their holdings in the Company to a third party, such Venkol entities may cause the holder to sell all shares of capital stock of the Company then owned by such holder to the third party. Further, the Stockholders' Agreement may provide that to the extent requested by the managing underwriter in the event of and in respect of an underwritten offering of securities of the Company, the holder will agree to refrain from selling or offering to sell any securities of the Company for such reasonable period of time after the effective date of the registration statement relating to the underwritten offering as the holders of at least seventy-five percent (75%) of the outstanding shares of the Company's Class A Preferred Stock will have agreed to refrain from selling or offering to sell their Class A Preferred Stock and/or Common Stock in the Company issuable upon conversion thereof (the "Underwriter's Lockup"); and 4

(5) in the event such holder is an employee of the Company or a Subsidiary, such Escrow Agreement, Pledge Agreement or other agreement as the Company may require (the "Deposit Agreement"), pursuant to which such holder shall deposit, upon such exercise by the holder, with the Company or such third party as may be designated by the Company therefore, the Option shares acquired pursuant to the exercise of such Option, together with stock powers executed in blank by such holder with respect to such Option shares as may be determined by the Company, all so as to facilitate the enforcement of the Underwriter's Lockup described above, the other provisions of the Stockholders' Agreement, and/or the repurchase by the Company of the Option shares described in Paragraph 14 below, and which Deposit Agreement shall .remain in effect until the termination, if at all, of the Stockholders' Agreement (at which time. the Option Shares and related stock powers would be returned). (ii) No shares shall be issued until full payment therefore has been made. (iii) In the event the representation described in Paragraph 7(c)(i)(2) above is required and made and/or the holder executes and delivers the Stockholders' Agreement, the Committee may cause each certificate evidencing the purchased Common Stock to be endorsed with one or more legends setting forth the restrictions on transfer or otherwise of such Common Stock. (d) The holder of an Option shall have none of the rights of a stockholder with respect to the shares purchasable upon exercise of the Option until a certificate for such shares shall have been issued to the holder upon due exercise of the Option. (e) The proceeds received by the Company upon exercise of an Option shall be added to the Company's working capital and be available for general corporate purposes. 8. Non-Transferability of Options No Option granted pursuant to the Plan shall be transferable otherwise than by will or the laws of descent and distribution, and an Option may be exercised during the lifetime of the holder only by such holder. 9. Termination of Employment of Holder of Option In the event the employment with the Company or a Subsidiary of the holder of an Option shall be terminated for any reason other than by reason of death, disability within the meaning of Section 22(e)(3) of the Code, or retirement at or after age 65, such holder's Option shall immediately terminate, lapse and expire. Absence on leave approved by the employer corporation or entity shall not be considered an interruption of employment for any purpose under the Plan.

Nothing in the Plan or in any Option Agreement granted hereunder shall confer upon any Optionholder any right to commence or continue in the employ of the Company or any Subsidiary or obligate the Company or any Subsidiary to commence or continue the employment of any Optionholder or interfere in any way with the right of the Company or any such Subsidiary to terminate such Optionholder's employment, if any, at any time. 10. Retirement or Disability of Holder of Option If the employment with the Company or a Subsidiary of the holder of an Option shall be terminated by reason of such holder's disability within the meaning of Section 22(e) (3) of the Code, or retirement at or after age 65, such holder (or such holder's legal representative, on such holder's behalf, if applicable) may, within six months from the date of such termination, exercise such Option, but only to the extent such Option was exercisable by such holder at the date of such termination. Notwithstanding the foregoing, no Option may be exercised subsequent to the date of its expiration. 11. Death of Holder of Option If the holder of any Option shall die while in the employ of the Company or a Subsidiary (or within six months following termination of employment due to disability within the meaning of Section 22(e) (3) of the Code, or retirement at or after age 65), the Option theretofore granted to such person may be exercised, but only to the extent such Option was exercisable by such holder at the date of death (or the date of termination of employment due to disability or retirement at or after age 65) by the legatee or legatees of such person under such person's Last Will, or by such person's personal representative or distributees, within six months from the date of death but in no event subsequent to the expiration date of the Option. 12. Adjustments Upon Changes in Capitalization If at any time after the date of grant of an Option, the Company shall by stock dividend, split-up, combination, reclassification or exchange, or through merger or consolidation or otherwise, change its shares of Common Stock into a different number or kind or class of shares or other securities or property, then the number of shares covered by such Option and the price per share thereof shall be proportionately adjusted for any such change by the Committee, whose determination thereon shall be conclusive. In the event that a fraction of a share results from the foregoing adjustment, said fraction shall be eliminated and the price per share of the remaining shares subject to the Option adjusted accordingly. 13. Vesting of Rights Under Options Neither anything contained in the Plan nor in any resolution adopted or to be adopted by the Committee or the stockholders of the Company shall constitute the vesting of any rights under any Option. The vesting of such rights shall take place only when a written Option Agreement, substantially in the form of the Stock Option Agreement attached hereto as Exhibit A shall be duly executed and delivered by and on behalf of the Company and the person to whom the Option shall be granted. 6

14. Repurchase of Option Shares by the Company In the event Option shares are purchased by any individual who is an employee of the Company or a Subsidiary pursuant to any Option granted under the Plan, and such individual's employment shall terminate for any reason whatsoever (including, without limitation, by reason of death, disability or retirement), and the Company's Common Stock is not then listed on a national securities exchange or traded on NASDAQ, and the Company in its sole and absolute discretion elects to purchase such Option shares (the Company being under no obligation to do so), such individual shall agree to sell to the Company all Option shares acquired by such individual under this Plan for a purchase price equal to the fair market value of such Option shares as determined by the Committee based on a price that might be arrived at by a willing buyer and a willing seller, neither being under a compulsion to buy or to sell, and taking into account such factors as it shall deem appropriate, including, without limitation, the restricted nature of such Option shares, including by virtue of the provisions of the Stockholders' Agreement, the minority equity ownership position represented by the Option shares (i.e.. such Option shares would be valued at a lower price by virtue thereof than that which might otherwise be calculated in respect of the relative percentage equity ownership of the Company represented by such Option shares), and the option price established by the Committee as applicable to the then most recent incentive stock options granted by the Company (whether hereunder or otherwise within the meaning of Section 422 (b) of the Code), and such other factors as the Committee may deem appropriate. The foregoing determination hereunder by the Committee of the fair market value of the Option shares shall be conclusive and not subject to review. 15. Termination and Amendment The Plan, which has been adopted by the Board of Directors on June 15, 2000 and by the stockholders of the Company on ________________, shall terminate on June 14, 2010, and no Option shall be granted under the Plan after such date. The Board of Directors may at any time prior to such date terminate the Plan or make such modifications or amendments thereto as it shall deem advisable; provided, however, that: (i) no increase shall be made in the aggregate number of shares which may be issued under, the Plan; (ii) no such termination, modification or amendment shall materially adversely affect the rights of a holder of an Option previously granted under the Plan; (iii) no modification shall be made to the requirements of eligibility for participation in the Plan; and (iv) no material increase shall be made in the benefits accruing to participants under the Plan.

Remedies. Your obligations under the Proprietary Information and Inventions Agreement and the provisions of Sections 4.2, 7, 8, 9, and 11 of this Agreement (as modified by Section 14, if applicable) shall survive the expiration or termination of your employment (whether through your resignation or otherwise) with the Company. You acknowledge that a remedy at law for any breach or threatened breach by you of the provisions of the Proprietary Information and Inventions Agreement or Section 4 or 7 hereof would be inadequate and you therefore agree that the Company shall be entitled to such injunctive relief in case of any such breach or threatened breach. -5-

Interpretation. IT IS THE INTENT OF THE PARTIES THAT in case any one or more of the provisions contained in this Agreement shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect the other provisions of this Agreement, and this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein.

Assignment of Inventions 3.1 I hereby acknowledge and agree that the Company is the owner of all Inventions. In order to protect the Company's rights to such Inventions, by executing this Agreement I hereby irrevocably assign to the Company all my right, title and interest in and to all Inventions to the Company. 3.2 For purposes of this Agreement, "Inventions" shall mean all discoveries, processes, designs, methods, techniques, technologies, devices, or improvements in any of the foregoing or other ideas, whether or not patentable or copyrightable and whether or not reduced to practice, made or conceived by me (whether solely or jointly with others) during the period of my employment with the Company which relate in any manner to the actual or demonstrably anticipated business, work, or research and development of the Company, or result from or are suggested by any task assigned to me or any work performed by me for or on behalf of the Company. 3.3 Any discovery, process, design, method, technique, technology, device, or improvement in any of the foregoing or other ideas, whether or not patentable or copyrightable and whether or not reduced to practice, made or conceived by me (whether solely or jointly with others) which I develop entirely on my own time not using any of the Company's equipment, supplies, facilities, or trade secret information ("Personal Invention") is excluded from this Agreement provided such Personal Invention (i) does not relate to the actual or demonstrably anticipated business, research and development of the Company, and (ii) does not result, directly or indirectly, from any work performed by me for or on behalf of the Company. 4.

My disclosure shall be received in confidence by the Company. 5. Patents and Copyrights, Execution of Documents. 5.1 Upon request, I agree to assist the Company or its nominee (at its expense) during and at any time subsequent to my employment in every reasonable way to obtain for its own benefit patents and copyrights for Inventions in any and all countries.

I acknowledge that the Company from time to time may have agreements with other persons, companies, entities, the U.S. Government or agencies thereof, which impose obligations or restrictions on the Company regarding Inventions made during the course of work thereunder or regarding the confidential nature of such work. I agree to be bound by all such obligations and restrictions and to take all action necessary to discharge the Company's obligations. 8. Trade Secrets of Others. I represent that my performance of all the terms of this Agreement and as an employee of the Company does not and will not breach any agreement to keep confidential proprietary information, knowledge or data acquired by me in confidence or in trust prior to my employment with the Company, and I will not disclose to the Company, or induce the Company to use, any confidential or proprietary information or material belonging to any previous employer or others.

Each party shall endeavor to reach an agreement with the other regarding the manner, text and timing of any publicity to be given such matters in time to comply with any applicable regulatory requirements, but such agreement shall not be a precondition to any action that either Delcath or Nissho reasonably deems necessary to protect users of the Product or to comply with any applicable governmental orders.

It is contemplated that in the course of the performance of this Agreement each party may, from time to time, disclose Confidential Information to the other. Each party agrees to take all reasonable steps to prevent disclosure of Confidential Information; provided, however, no provision of this Agreement shall be construed so as to preclude such disclosure of Confidential Information as may be inherent in or reasonably necessary for marketing Products pursuant to this Agreement, or for securing from any governmental agency any necessary approval or license relating to the subject or performance of this Agreement. 6.3 Regulatory Requirements; Clinical Trials. (a) Nissho will notify Delcath in a timely manner of all applicable laws, rules and regulations affecting the importation, distribution, sale and use of the Products in each 5

(c) Nissho shall send to Delcath copies, in the original language in which they were generated, of all reports and data from clinical trials, and all correspondence with the regulatory authorities in all countries in the Territory, including applications for regulatory approval, as soon as reasonably practicable after such materials are available to Nissho. Upon the request of Delcath, Nissho will provide Delcath with reasonable assistance in translation of such materials into English, provided that Nissho shall be indemnified for any costs incurred in connection with such assistance. 6.4 Non-Competition. Nissho agrees that from the date hereof until the date falling two (2) years after the date of termination of this Agreement and the exclusive distributorship created hereby except for the termination by Nissho under Article 5.2(a), it shall not, directly or indirectly, anywhere in the Territory, (i) engage in the business of manufacturing, distributing or selling devices or systems which isolate specific organs or body regions for the targeted delivery of anti-cancer compounds accompanied by the extra-corporeal treatment of blood (the "Business") or assist, advise, represent or consult for any other person or entity in connection with such person or entity engaging in the Business, (ii) induce, or attempt to induce, any employee of Delcath to leave such employ, or to accept any other position or employment or assist any other person or entity in hiring such employee, (iii) solicit, or attempt to solicit, any persons or entities who or which are customers of Delcath (as of the date of termination of this Agreement or at any time prior thereto) in connection with the engagement, by any person or entity, in the Business; or (iv) otherwise disrupt or interfere with, or attempt to disrupt or interfere with, Delcath's relations with any actual or potential customer or supplier or any other material relationship of Delcath. For purposes of this Section 6.4, the term "indirectly" shall include, without limitation, a reference to any business or entity in which Nissho participates in the management, operation, control or supervision or in which Nissho has any direct or indirect ownership or financial interest, other than the direct or indirect beneficial ownership by Nissho of less than four percent (4%) of the voting capital stock of a publicly held corporation. The provisions of this Section 6.4 shall not apply in the event this Agreement is rightfully terminated by Nissho under Section 5.2(a)(i) hereof on account of Delcath's uncured breach of this Agreement. 6.5 Minimum Annual Purchase Quantities.

The minimum annual purchase quantity in 6

effect for a product for resale and use in a country in the Territory is herein referred to as "Minimum Annual Purchase Quantity." Minimum Annual Purchase Quantities shall be based on factors including the incidence of disease, cost of the Delcath procedure, reimbursement amount and sales levels in other countries. In the event that the parties are unable to agree on any Minimum Annual Purchase Quantity either party may commence an arbitration proceeding as set forth in Section 9.4 hereof. 6.6 Manufacturing License. Within twelve (12) months of the commencement of sales anywhere in the Territory, Nissho and Delcath will commence discussions concerning the possibility of Nissho becoming a manufacturer of any or all of the components of the Products. 6.7 Facility Inspection.
