                   Subject to Completion. Dated April 19, 2004


                              DELCATH SYSTEMS, INC.

                     Up to 5,969,490 Shares of Common Stock

     This prospectus relates to two offerings of our common stock.

     The first offering is a primary offering by us of up to 3,098,070 shares
that may be issued upon the exercise of warrants that we issued in 2000 and 2003
and that are currently publicly traded. We will receive the proceeds of any
exercise of these warrants. If all of these warrants were to be issued, we would
receive net proceeds of approximately $[__________] (after our estimated
expenses of these offerings of $[_______]). Based on the recent prices of our
common stock on the Nasdaq SmallCap Market in comparison to the exercise price
of the 2003 Warrants, we expect that we will elect to redeem the 2003 Warrants
as promptly as practicable. Based on those prices in comparison to the exercise
price of our 2000 Warrants, we believe it is likely that few if any of the 2000
Warrants will be exercised.

     The second offering is the resale of:

     o    up to 1,879,636 shares that we issued in connection with the exercise
          of warrants we issued as part of a private placement in 2002 and in
          private placements in 2004 (including shares that we may issue upon
          exercise of the warrants we issued as part of the private placements
          in 2004); and

     o    up to 991,784 shares that we might issue on the exercise of unit
          warrants to the underwriters of our public offerings and of warrants
          that we might issue upon exercise of warrants issued to the placement
          agents in our 2004 private placement.

     If any of the shares described in the preceding paragraph are resold, we
will not receive any of the proceeds which will go to the person who sells the
shares.

     The exercise prices of our 2004 Warrants, 2003 Warrants and 2000 Warrants
are subject to adjustment, including anti-dilution provisions for corporate
events, such as stock splits. It is possible that none of the 2004 Warrants, the
2003 Warrants or the 2000 Warrants will be exercised.

     Our common stock is currently traded on the Nasdaq Small Cap Market and the
Boston Stock Exchange under the symbols "DCTH" and "DCT," respectively. Our 2000
Warrants currently trade on the Nasdaq Small Cap Market under the symbol "DCTW."
Our 2003 Warrants currently trade on the OTC Bulletin Board and the Boston Stock
Exchange under the symbols "DCTHZ" and "DCT&W," respectively. On April __, 2004,
our common stock had a closing price of $ ______ per share, our 2003 Warrants
had a closing price of $0.__ per Warrant and our 2000 Warrants had a closing
price of $0.__ per Warrant.

                                  RISK FACTORS

     You should consider carefully the following factors, as well as the other
information set forth in this prospectus, prior to making an investment in our
securities. If any of the following risks and uncertainties actually occur, our
business, financial condition or operating results may be materially and
adversely affected. In this event, the trading price of our securities, as
applicable, may decline and you may lose part or all of your investment.

Related to Our Business and Financial Condition

     The following factors relate to risks that are material to our business and
financial condition. If any of the possible events we describe below turns out
to be the case, our business may be adversely affected and we may be forced to
cease or curtail our operations which may result in the loss of your entire
investment.

          Our entire focus has been the development and commercialization of the
          Delcath system.

     The Delcath system, an enabling technology for the isolation of various
organs in the body to permit the delivery of otherwise unacceptably toxic doses
of drugs, is our only product. If the Delcath system fails as a commercial
product, we have no other products to sell.

     Continuing losses may exhaust our capital resources. We have no revenue to
date, a substantial accumulated deficit, recurring operating losses and negative
cash flow.

     We expect to incur significant and increasing losses while generating
minimal revenues over the next few years. From our inception on August 5, 1988
through December 31, 2003, we have incurred cumulative losses of $18.2 million
which were principally incurred in connection with our product development
efforts. For the years ended December 31, 2002 and December 31, 2003, we
incurred net losses of $1.8 million and $2.3 million, respectively.

     We have funded our operations through a combination of private placements
of our securities and through the proceeds of our public offerings in 2000 and
2003. Please see a detailed discussion of our various sales of securities
described in Note 2 to our 2003 financial statements that are included in our
Annual Report on Form 10-KSB for the year ended December 31, 2003. In addition,
we received gross proceeds of approximately $3.5 million from private placements
we completed in 2004 and approximately $[__] million on exercise of warrants in
2004.

     If we continue to incur losses we may exhaust our capital resources,
including those raised in this offering. As of December 31, 2003, we had cash
and cash equivalents and short term investments of $2.3 million.

          We will likely need additional funding to complete our planned
          clinical trials and our efforts to raise additional financing may be
          unsuccessful.

     Our resources may not be sufficient to enable us to complete our Phase III
clinical trials and obtain FDA premarket approval for the use of doxorubicin
with our Delcath system 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 or obtain FDA pre-marketing approval
for the use of doxorubicin with the Delcath system. Our ability to complete the
Phase III clinical trials could be lessened to the extent we devote assets to
clinical trials using melphalan with the Delcath system.








          If we do not raise any additional capital that may be required to
          commercialize the Delcath system, our potential to generate future
          revenues will be significantly limited even if we receive FDA
          premarket approval.

     Our current resources may not be sufficient to complete Phase III clinical
trials using doxorubicin and will be insufficient to fund the costs of
commercializing the Delcath system which will be significant. 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 commercially.

Risks Related to FDA and Foreign Regulatory Approval

     The following factors relate to risks that are material to obtaining FDA
and foreign regulatory approval. If any of the events we describe below turns
out to be the case, our business may be adversely affected and we may be forced
to cease or curtail our operations which may result in the loss of your entire
investment.

          If the FDA refuses to grant premarket approval or limits the
          circumstances under which the Delcath system may be used, our ability
          to market the Delcath system will be greatly reduced.

     Premarket approval requires a determination by the FDA that the data
developed by our clinical trials show 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, for each of
primary liver cancer and metastatic melanoma, in a statistically rigorous
manner, increased patient survival times against a control group before it will
approve our application for premarket approval. Even if regulatory approval is
granted, the approval may limit the uses for which the Delcath system may be
marketed. If we fail to obtain FDA premarket approval, we will not be able to
market the Delcath system. Additionally, if we obtain FDA premarket approval
with substantial limitations on uses of the Delcath system, this would greatly
reduce the market for the system.

          If we do not obtain FDA premarket approval, we may not be able to
          export the Delcath system to foreign markets, which will limit our
          sales opportunities.

     If the FDA does not approve our application for premarket approval
application for the Delcath system, we will not be able to export the Delcath
system from the United States for marketing abroad unless approval has been
obtained from one of a number of developed nations. We have not begun to seek
foreign regulatory approval and may not be able to obtain approval from one or
more countries where we would like to sell the Delcath system. If we are unable
to market the Delcath system internationally because we are not able to obtain
required approvals, our international market opportunity will be materially
limited.

          Because of our limited experience, conduct of Phase III clinical
          trials and obtaining FDA premarket approval could be delayed.

     We have experienced and may continue to experience delays in conducting and
completing the trials, caused by many factors, including our limited experience
in arranging for clinical trials and in evaluating and submitting the data
gathered from clinical trials, in designing trials to conform to the trial
protocols authorized by the FDA, in complying with the requirements of
institutional review boards at the sites where the trials will be conducted and
in identifying clinical test sites and sponsoring physicians. Completion of our
clinical trials will also depend on the ability of the clinical test sites to
identify patients to enroll in the clinical trials. The trials may also take
longer to complete because of difficulties we may encounter in entering into
agreements with clinical testing sites to conduct the trials. Any significant
delay in completing clinical trials or in the FDA's responding to our submission
or a requirement by the FDA for us to conduct additional trials would delay the
commercialization of the Delcath system and our ability to generate revenues.



                                   -2-







          Third-party reimbursement may not be available to purchasers of the
          Delcath system or may be inadequate.

     Physicians, hospitals and other health care providers may be reluctant to
purchase our system 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, Medicare, Medicaid and private health insurance plans will
not reimburse its use in the United States. We will not begin to seek to have
third-party payors reimburse the cost of the Delcath system until after its use
is approved by the FDA. Each third-party payor independently determines whether
and to what extent it will reimburse for a medical procedure or product.
Third-party payors in the United States or abroad may decide not to cover
procedures using the Delcath system. Further, third-party payors may deny
reimbursement if they determine that the Delcath system is not used in
accordance with established payor protocols regarding cost effective treatment
methods or is used for forms of cancer or with drugs not specifically approved
by the FDA.

     New products are under increased scrutiny as to whether or not they will be
covered by the various healthcare plans and the level of reimbursement which
will be applicable to respective covered products and procedures. A third-party
payor may deny reimbursement for the treatment and medical costs associated with
the Delcath system, notwithstanding FDA or other regulatory approval, if that
payor determines that the Delcath system is unnecessary, inappropriate, not cost
effective, experimental or is used for a non-approved indication.

Risks Related to Manufacturing, Commercialization and Market Acceptance of the
Delcath System

          We obtain necessary components for the Delcath system from sole-source
          suppliers. Because manufacturers must demonstrate compliance with FDA
          requirements, if our present suppliers fail to meet such requirements
          or if we change any supplier, the successful completion of the
          clinical trials and/or the commercialization of the Delcath system
          could be jeopardized.

     We must ensure that the components of the Delcath system are manufactured
in accordance with manufacturing and performance specifications of the Delcath
system on file with the FDA and with drug and device good manufacturing practice
requirements. Many of the components of the Delcath system are manufactured by
sole source suppliers. If any of our suppliers fails to meet our needs, or if we
need to seek an alternate source of supply, we may be forced to suspend or
terminate our clinical trials. Further, if we need a new source of supply after
commercial introduction of the Delcath system, we may face long interruptions in
obtaining necessary components, which could jeopardize our ability to supply the
Delcath system to the market.

          We do not have any contracts with suppliers for the manufacture of
          components for the Delcath system. If we are unable to obtain an
          adequate supply of the necessary components, we may not be able timely
          to complete our clinical trials.

     We do not have any contracts with suppliers for the manufacture of
components for the Delcath system. Certain components are available from only a
limited number of sources. 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 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, commercialization of the Delcath system could be delayed.


                                      -3-


          


     Because of our limited experience in marketing products and our lack of
adequate personnel to market and sell products, we may not be successful in
marketing and selling the Delcath system even if we receive FDA premarket
approval.

     We have not previously sold, marketed or distributed any products and
currently do not have the personnel, resources, experience or other capabilities
to market the Delcath system adequately. Our success will depend upon our
ability to attract and retain skilled sales and marketing personnel. Competition
for sales and marketing personnel is intense, and we may not be successful in
attracting or retaining such personnel. Our inability to attract and retain
skilled sales and marketing personnel could adversely affect our business,
financial condition and results of operations.

          Market acceptance of the Delcath system will depend on substantial
          efforts and expenditures in an area with which we have limited
          experience.

     Market acceptance of the Delcath system will depend upon a variety of
factors including whether our clinical trials demonstrate a significant
reduction in the mortality rate for the kinds of cancers treated on a
cost-effective basis, our ability to educate physicians on the use of the
Delcath system and our ability to convince healthcare payors that use of the
Delcath system results in reduced treatment costs to patients. We have only
limited experience in these areas and we may not 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. As a result, the
Delcath system may not gain significant market acceptance among physicians,
hospitals, patients and healthcare payors.

          Rapid technological developments in treatment methods for liver cancer
          and competition with other forms of liver cancer treatments could
          result in a short product life cycle for the Delcath system.

     Competition in the cancer treatment industry, particularly in the markets
for systems and devices to improve the outcome of chemotherapy treatment, is
intense. The Delcath system competes with all forms of liver cancer treatments
that are alternatives to the "gold standard" treatment of surgical resection.
Many of our competitors have substantially greater resources, especially
financial and technological. In addition, some of our competitors have
considerable experience in conducting clinical trials and other regulatory
procedures. These competitors are developing systems and devices to improve the
outcome of chemotherapy treatment for liver cancer. If these competitors develop
more effective or more affordable products or treatment methods, our
profitability will be substantially reduced and the Delcath system could have a
short product life cycle.

Risks Related to 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
medical devices to the market, the healthcare industry has traditionally placed
considerable emphasis on patent and trade secret protection for significant new
technologies. 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 could be costly and could divert our attention from our
business. If others file patent applications with respect to inventions for
which we already have patents issued to us 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 could also be costly and could divert our attention from our business. If
a third party violates our intellectual property rights, we may be unable to
enforce our rights


                                      -4-





because of our limited resources. Use of our limited funds to defend our
intellectual property rights may also affect our financial condition adversely.

Risks Related to Products Liability

     We do not currently carry products liability insurance and we may not be
able to acquire sufficient coverage in the future to cover large claims.

     Clinical trials, manufacturing 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 products 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. A successful products liability
claim or recall would have a material adverse effect on our business, financial
condition and results of operations.

Risks Related to an Investment in Our Securities

     The following factors relate to risks that are material to an investment in
our common stock. Any of these factors could result in lowering the market value
of our common stock and our warrants.

     There is a limited public float of our common stock and of our 2000
Warrants 2003 Warrants. Because of this, trades of relatively small amounts of
our common stock can have a disproportionate effect on the market price for our
common stock. The market price of our common stock may be volatile.

     Of our outstanding common stock, approximately [two-thirds] (including the
shares that could be sold by the selling security holders named herein) can be
considered to be in the public float. The term "public float" refers to shares
freely and actively tradeable on the Nasdaq Small Cap Market and/or the Boston
Stock Exchange and not beneficially owned by officers, directors or affiliates,
as such term is defined under the Securities Act. Because of the relatively
small public float and the limited trading volume of our common stock, purchases
and sales of relatively small amounts of our common stock can have a
disproportionate effect on the market price for our common stock. As a result,
the market price of our common stock can be volatile.

          The number of shares eligible for future sale may cause the market
          price of our common stock to be below the level it otherwise would.

     The potential for sales of substantial amounts of our common stock, or
"equity overhang," could adversely affect the market price of our common stock.
As of April 15, 2004, [_______] shares of our common stock will be outstanding.
Of these shares, [_______] (including the shares that could be sold by the
selling security holders named herein) will be freely tradable without
restriction or further registration under the Securities Act. The remaining
[_______] shares of our common stock outstanding and held by existing
stockholders will be considered "restricted securities" under the Securities Act
and eligible for sale in compliance with Rule 144. Rule 144 provides volume and
manner of sale restrictions and holding periods, which expire after the holder
of our common stock ceases to meet the definitions of affiliate or underwriter.

     In addition, we may issue substantial amounts of common stock upon exercise
of options outstanding under our stock option plans.

     Sales of substantial amounts of common stock following this offering, or
the perception that such sales could occur, could have an adverse effect on
prevailing market prices for our common stock and our publicly-traded warrants.

          Anti-takeover provisions in our certificate of incorporation and
          by-laws and under Delaware law and our stockholder rights agreement
          may reduce the likelihood of a potential change of control.


                                      -5-







     Provisions of our certificate of incorporation, by-laws and Delaware law
may have the effect of discouraging, delaying or preventing a change in control
of us or unsolicited acquisition proposals that a stockholder might consider
favorable. These include provisions:

     o    providing for a classified board and permitting the removal of a
          director only for cause;

     o    authorizing the board of directors to fill vacant directorships or
          increase the size of our board of directors; and

     o    subjecting us to the provisions of Section 203 of the Delaware General
          Corporate Law, which provides that a Delaware corporation may not
          engage in any of a broad range of business combinations with a person
          or entity who owns 15% or more of the outstanding voting stock of a
          company for a period of three years from the date the person or entity
          became an interested stockholder unless (a) prior to such time our
          board of directors approved either the business combination or the
          transaction which resulted in the stockholder's becoming an interested
          stockholder or (b) upon consummation of the transaction which resulted
          in the stockholder's becoming an interested stockholder, the
          interested stockholder owned at least 85% of the voting stock of the
          corporation outstanding at the time the transaction commenced or (c)
          at or subsequent to such time the business combination is approved by
          the board of directors and authorized at an annual or special meeting
          of stockholders by the affirmative vote of at least 66 2/3% of the
          outstanding voting stock not owned by the interested stockholder.

     Furthermore, our board of directors has the authority to issue shares of
preferred stock in one or more series and to fix the rights and preferences of
the shares of any such series without stockholder approval. Any series of
preferred stock is likely to be senior to the common stock with respect to
dividends, liquidation rights and, possibly, voting rights. Our board's ability
to issue preferred stock may have the effect of discouraging unsolicited
acquisition proposals, thus adversely affecting the market price of our common
stock and warrants.

     We also have a stockholder rights agreement which could have the effect of
substantially increasing the cost of acquiring us unless our board of directors
supports the transaction even if the holders of a majority of our common stock
are in favor of the transaction.

          Our common stock is listed on the Nasdaq SmallCap Market. If we fail
          to meet the requirements of The Nasdaq Stock Market for continued
          listing, our common stock could be delisted.

     Our common stock is currently listed on the Nasdaq SmallCap Market. To keep
such listing, we are required to maintain: (i) a minimum bid price of $1.00 per
share, (ii) a certain public float, (iii) a certain number of round lot
shareholders and (iv) one of the following: a net income from continuing
operations (in the latest fiscal year or two of the three last fiscal years ) of
at least $500,000, a market value of listed securities of at least $35 million
or a stockholders' equity of at least $2.5 million. At times, we have not met
one or more of these criteria. If we do not meet all of the applicable criteria,
our common stock could be delisted from the Nasdaq SmallCap Market.

          If our common stock is delisted from the Nasdaq SmallCap Market, we
          may be subject to the risks relating to penny stocks.

     If our common stock were to be delisted from trading on the Nasdaq SmallCap
Market and the trading price of the common stock remains below $5.00 per share
on the date the common stock were delisted, trading in such securities would
also be subject to the requirements of certain rules promulgated under the
Exchange Act. These rules require additional disclosure by broker-dealers in
connection with any trades involving a stock defined as a penny stock and impose
various sales practice requirements on broker-dealers who sell penny stocks to
persons other than established customers and accredited investors, generally


                                      -6-





institutions. The additional burdens imposed upon broker-dealers by such
requirements may discourage broker-dealers from effecting transactions in our
securities, which could severely limit the market price and liquidity of such
securities and the ability of purchasers to sell our securities in the secondary
market.

     A penny stock is defined generally as any non-exchange listed equity
security that has a market price of less than $5.00 per share, subject to
certain exceptions.

          California investors may not be able to resell the securities.

     Our public offering in 2003 was approved in California on the basis of a
limited offering qualification. Investors who are residents of California must
meet a "super suitability" standard of not less than $250,000 liquid net worth
(exclusive of home, home furnishings and automobiles), plus $65,000 gross annual
income or $500,000 liquid net worth or $1,000,000 net worth (inclusive of home,
home furnishings and automobiles) or $200,000 gross annual income. We did not
have to demonstrate compliance with some or all of the merit regulations of the
California Department of Corporations, as found in Title 10, California Code of
Regulations, Rule 260.140 et seq.

     Residents of the State of California may be unable to sell shares of common
stock they purchase in this offering, and investors residing in all other states
may be unable to sell shares of common stock they purchase in this offering to
California residents, pursuant to exemptions for secondary trading available
under California Corporations Code Section 25104(h), as such exemptions have
been withheld. However, secondary sales may be made to purchasers who meet the
"super suitability" standards or there may be other exemptions to cover private
sales by the bona fide owners of our securities for such owners' own account
without advertising and without being effected by or through a broker dealer in
a public offering.

                                  OUR BUSINESS


General

     Since our founding in 1988, we have been a development stage company
engaged primarily in developing a drug-delivery system which is designed to
isolate the liver from the general circulatory system and to administer
chemotherapy and other therapeutic agents directly to the liver. Our objectives
are 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.

     A more complete description of our business is contained in our Annual
Report on Form 10-KSB for the year ended December 31, 2003. See "Incorporation
of Certain Documents by Reference."

Terms of our Common Stock


     As of April 15, 2004, there were ________ shares of our common stock
outstanding. Assuming all outstanding 2004 Warrants, 2003 Warrants (including
the unit warrants issued to the underwriters) and 2000 Warrants (including the
unit warrants issued to the underwriters) are exercised for the issuance of
___________ shares of common stock, there would be __________ shares of common
stock outstanding.

     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


                                      -9-





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.

     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.

Terms of the 2004 Warrants

     As of the date hereof, there were 446,256 outstanding 2004 Warrants
(including those issued to the placement agents in connection with the private
placements). Each 2004 Warrant entitles the holder thereof to purchase one share
of common stock at a price of $3.01 per share. The 2004 Warrants are redeemable
as described above under "The Offering."

Terms of the 2003 Warrants

     As of the date hereof, there were 1,898,070 outstanding 2003 Warrants. Each
2003 Warrant entitles the holder thereof to purchase one share of common stock
at a price of $0.775 per share, subject to adjustment, at any time up to May 20,
2008. Each unit warrant held by Roan/Myers Associates, L.P. or its transferees
entitles the holder thereof to purchase five shares of our common stock and five
2003 Warrants for a purchase price of $5.12. The 2003 Warrants issuable upon
exercise of the unit warrant would have the same terms as the provisions of the
other 2003 Warrants except that the exercise price of such warrants is $1.28 per
share. The 2003 Warrants are redeemable as described above under "The Offering."

     Assuming that the registration statement of which this prospectus is a part
becomes effective by May 20, 2004 and that the average closing price of our
common stock for the 20 trading days ending on May 20, 2004 is at least $1.24,
we anticipate that we would send a notice of redemption to all the holders of
the 2003 Warrants. Under those circumstances any holder of a 2003 Warrant who
does not exercise his 2003 Warrant by the date specified in the notice of
redemption would receive a cash payment of $0.01 per 2003 Warrant and would not
thereafter be able to exercise the 2003 Warrant.

     The 2003 Warrants were issued in registered form under a warrant agent
agreement by and between Delcath and American Stock Transfer & Trust Company, as
warrant agent. Reference is made to the warrant agent agreement, dated as of May
20, 2003, which was filed as Exhibit 4.8 to Amendment No. 3 to the Company's
Registration Statement on Form SB-2 (No. 333-101661) for a complete description
of the terms and conditions thereof.

Terms of the 2000 Warrants

     As of the date hereof, there were 1,200,000 outstanding 2000 Warrants. Each
2000 Warrant entitles the holder thereof to purchase one share of common stock
at a price of $6.60 per share, subject to adjustment, at any time up to October
15, 2005. Each unit warrant held by Whale Securities Co., L.P., the underwriter
for our 2000 initial public offering, entitles Whale Securities to purchase one
share of common stock and one 2000 Warrant at a price of $6.60. The 2000
Warrants issuable upon exercise of the unit warrant would have the same
provisions as the other 2000 Warrants except that the exercise price of such
warrants is $10.50 per share. The 2000 Warrants are redeemable as described
above under "The Offering."

     The 2000 Warrants were issued in registered form under a warrant agreement
between and among Delcath, Whale Securities Co., L.P. and American Stock
Transfer & Trust Company, as warrant agent. Reference is made to the warrant
agreement which was filed as Exhibit 4.2 to Amendment No. 5 to the


                                      -10-





Company's Registration Statement on Form SB-2 (No. 333-333-39470) for a complete
description of the terms and conditions thereof.

Transfer Agent

     The transfer agent for our common stock, 2003 Warrants and 2000 Warrants is
American Stock Transfer & Trust Company. The Company acts as the transfer agent
for the 2004 Warrants and the unit warrants issued to Roan/Meyers Associates,
L.P. and to Whale Securities Co., L.P.

                                 USE OF PROCEEDS

     In the event that all of our outstanding 2004 Warrants, 2003 Warrants and
2000 Warrants, including those warrants held by the placement agents for our
2004 private placements and unit warrants held by the underwriters of our 2003
and 2000 public offerings, are exercised, we estimate that the net proceeds from
the sale by us of shares of our common stock being offered by this prospectus,
after deducting the estimated expenses of this offering will be approximately
$__________________. However, the actual number of warrants exercised will
depend on numerous factors beyond our control, including, without limitation,
the market price of our common stock. Based on the recent trading prices of our
common stock, we believe it is reasonable to assume that, if we call the 2003
Warrants for redemption in accordance with their terms, a substantial portion of
the 2003 Warrants and the unit warrants issued to the managing underwriter of
our 2003 public offering will be exercised. Whether other warrants are likely to
be issued will probably depend on the market prices of our common stock between
the date hereof and the expiration date of the particular warrant. We cannot
estimate with reasonable accuracy the number of such warrants which may be
exercised and the amount of proceeds to be received therefrom.

     We expect that we would use any proceeds we receive upon exercise of any of
the 2004 Warrants, the 2003 Warrants and the 2000 Warrants (including any
exercise by the managing underwriters or placement agents) for working capital
purposes.

     Prior to expenditure, proceeds will be invested principally in high grade,
short-term, interest-bearing instruments.

                              SELLING SHAREHOLDERS

     The following table sets forth the number and percentage of shares that are
being registered by this Prospectus for the account of the entities listed below
(the "Selling Shareholders"). The shares may be sold by the Selling
Shareholders, or any of their assigns, pursuant to the exercise of some or all
of our currently outstanding 2004 Warrants, 2003 Warrants and 2000 Warrants from
time to time in the public marketplace. The Selling Shareholders are not
obligated to exercise any of their warrants. All information contained in the
table below is based on information provided to us by the Selling Shareholders,
and we have not independently verified this information. The Selling
Shareholders are not making any representation that the shares covered by this
prospectus will be offered for sale. The Selling Shareholders may from time to
time offer and sell pursuant to this prospectus any or all of the shares being
registered for resale.

     The applicable percentages of ownership are based on an aggregate of
______________, shares of our common stock issued and outstanding as of April
15, 2004 plus, in the case of each Selling Shareholder, the number of shares
such Selling Shareholder could acquire within 60 days on exercise of warrants.
None of the Selling Shareholders has had a material relationship with us, or
with our predecessors or affiliates, at any time during the past three years.

(1)  Unless otherwise noted, all of the shares shown are held by individuals or

     shares. Shares not outstanding but deemed beneficially owned by virtue of
     the right of a person to acquire them within 60 days, by the exercise of
     options or warrants or conversion of preferred stock, are deemed
     outstanding in determining the number of shares beneficially owned by such
     person. Because the Selling Shareholders may choose not to sell any of the
     shares offered by this prospectus, and because there are currently no
     agreements, arrangements or undertakings with respect to the sale of any of
     the shares of common stock, we cannot estimate the number of shares that
     the Selling Shareholders will hold after completion of the offering. For
     purposes of this table, we have assumed that the Selling Shareholders will
     have sold all of the shares covered by this prospectus upon the completion
     of the offering.

                              PLAN OF DISTRIBUTION

     The common stock offered by us hereby is issuable by us upon the exercise
of some or all of our currently outstanding 2004 Warrants, 2003 Warrants and
2000 Warrants. The common stock offered hereby may be offered for sale and sold
from time to time by the persons or entities described in this prospectus under
the heading "Selling Shareholders," or by pledgees, donees, transferees or other
successors in interest after the effective date of the registration statement of
which this prospectus is a part.

     The Selling Shareholders, or their pledgees, donees, transferees or other
successors in interest, will act independently of us and of each other in making
decisions with respect to the timing, manner and size of each sale. Such sales
may be made on the Nasdaq SmallCap Market or otherwise, at prevailing prices and
on terms then prevailing or at prices related to the then market price, or in
negotiated transactions.

     The manner in which the common stock offered hereby may be sold by the
Selling Shareholders include, without limitation, the following:

     o    block trades in which the broker-dealer(s) engaged by any of the
          Selling Shareholders will attempt to sell common stock as agent but
          may position or resell a portion of the block as principal to
          facilitate the transaction;

     o    purchases by the broker-dealer(s) as principals and resale by such
          broker-dealer(s) for their account pursuant to this prospectus;

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

     o    negotiated transactions;



                                      -15-






     o    a combination of any such methods of sale;

     o    through the writing or settlement of options or other hedging
          transactions, whether through an options exchange or otherwise; or

     o    any other method permitted pursuant to applicable law.

     In effecting sales, broker-dealers engaged by the Selling Shareholders may
arrange for other broker-dealers to participate.

     In order to comply with the securities laws of certain states, if
applicable, the common stock offered hereby may be sold in such jurisdictions
only through registered or licensed brokers or dealers. In addition, in certain
states the common stock offered hereby may not be sold unless it has been
registered or qualified for sale in the applicable state or an exemption from
the registration or qualification requirement is available and is complied with
by us and the Selling Shareholders.

     The Selling Shareholders and any brokers, dealers, agents or underwriters
who participate in the sale of the common stock offered hereby may be deemed to
be "underwriters" within the meaning of Section 2(11) of the Securities Act, and
the commissions paid or discounts allowed to any such brokers, dealers, agents
or underwriters, in addition to any profits received on resale of the common
stock offered hereby, if any such broker, dealer or agent should purchase any
common stock offered hereby as a principal, may be deemed to be underwriting
discounts or commissions under the Securities Act.

     Under applicable rules under the Securities Exchange Act, any person
engaged in the distribution of the common stock may not simultaneously engage in
market making activities with respect to our common stock for a period of one
business day prior to the commencement of such distribution. In addition and
without limiting the foregoing, the Selling Shareholders will be subject to
applicable provisions of the Securities Exchange Act, and the rules thereunder,
including without limitation Regulation M, which provisions may limit the timing
of purchases and sales of common stock by the Selling Shareholders.

     Although we will receive the proceeds of the exercise of the 2004 Warrants,
2003 and the 2000 Warrants (see "Use of Proceeds," described above), we will not
receive any part of the proceeds from the sale of the common stock offered
hereby by the Selling Shareholders. We are required to pay all fees and expenses
incident to the registration of the shares. However, we are not obligated to
bear, and will not bear, any underwriting discounts or commissions relating to
the use by the Selling Shareholders of an underwriter in connection with the
disposition of the common stock offered hereby by the Selling Shareholders.

     We cannot assure you that the Selling Shareholders will sell any or all of
the common stock offered by them hereby. The common stock offered hereby by the
Selling Shareholders also may be sold pursuant to an available exemption from
the registration requirements of the Securities Act, including without
limitation Rule 144 promulgated thereunder. The sale of common stock by
"affiliates" (as defined in Rule 144(a) under the Securities Act) are subject to
the volume and manner of sale restrictions set forth in Rule 144.

     We have agreed to indemnify the Selling Shareholders against certain
losses, claims, damages and liabilities, including liabilities under the
Securities Act.

                                  LEGAL MATTERS

     The validity of the common stock offered hereby has been passed upon for
Delcath by Murtha Cullina, LLP, New Haven, Connecticut, counsel for Delcath.

               DISCLOSURE OF THE SEC'S POSITION ON INDEMNIFICATION
                         FOR SECURITIES ACT LIABILITIES

     Our certificate of incorporation provides that we must, to the fullest
extent permitted or required by the Delaware General Corporation Law, indemnify
any and all persons whom we have the power to indemnify from and against any and
all of the expenses, liabilities or other matters referred to in or covered by
the Delaware General Corporation Law. The indemnification provided for in our
certificate of incorporation is not exclusive of any other rights to which those
indemnified may be entitled under any law, agreement, vote of shareholders or
disinterested directors or otherwise.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to our directors, officers and controlling persons pursuant to
the foregoing provisions or otherwise, we have been advised that in the opinion
of the SEC such indemnification is against public policy as expressed in the
Securities Act of 1933 and is, therefore, unenforceable.

Item 15. Indemnification of Directors and Officers

     Section 145 of the Delaware General Corporation Law 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:

          o    breaches of the director's duty of loyalty to the corporation or
               its stockholders;

          o    acts or omissions not made in good faith or which involve
               intentional misconduct of knowing violations of law;

          o    liability for dividends paid or stock repurchased or redeemed in
               violation of the Delaware General Corporation Law; or

          o    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.

     As authorized by the Delaware General Corporation Law, Article Seventh of
the Company's Certificate of Incorporation provides that the personal liability
of the directors of the Company be eliminated to the fullest extent permitted
under Section 102(b) of the Delaware General Corporation Law.

     Article Eighth of the Company's Certificate of Incorporation and the
Company's By-laws provide that all persons whom the Company 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


                                      II-1





in effect), shall be indemnified by the Company 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.

     The Company maintains a liability and indemnification insurance policy in
the amount of $2,500,000 for a period extending from October 19, 2003 to October
19, 2004 issued by Carolina Casualty Insurance Company covering all our officers
and directors, at an annual expense of $60,000.

Item 17. Undertakings

     We hereby undertake:

     To file, during any period in which offers or sales of securities are made
a post-effective amendment to this registration statement to include any
additional or changed material information on the plan of distribution;

     For determining liability under the Securities Act, to treat each
post-effective amendment as a new registration statement of the securities
offered and the offering of the securities at that time to be the initial bona
fide offering; and

     To file a post-effective amendment to remove from registration any of the
securities that remain unsold at the end of the offering.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to our directors, officers and controlling persons
pursuant to the provisions of our Certificate of Incorporation or Bylaws or
applicable Delaware law, or otherwise, we have been advised that in the opinion
of the Securities and Exchange Commission such indemnification is against public
policy as expressed in that Act and is, therefore, unenforceable.

     In the event that a claim for indemnification against such liabilities
(other than the payment by us of expenses incurred or paid by a director,
officer or controlling person of ours in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, we will, unless in the
opinion of our counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by us is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.



                                      II-3
