                              Delcath Systems, Inc.
                          (A Development Stage Company)

                     Notes to Condensed Financial Statements

Note 1: 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 (Investigational New Drug) for
its product by the FDA (Food and Drug Administration). The Company is seeking to
complete clinical trials in order to obtain separate FDA pre-market approvals
for the use of its delivery system using doxorubicin and melphalan,
chemotherapeutic agents, to treat malignant melanoma that has spread to the
liver.

Note 2: Basis of Presentation

The accompanying financial statements are unaudited and have been prepared by
the Company in accordance with accounting principles generally accepted in the
United States of America. Certain information and footnote disclosures normally
included in the Company's annual financial statements have been condensed or
omitted. The interim financial statements, in the opinion of management, reflect
all adjustments (consisting of normal recurring accruals) necessary for a fair
statement of the results for the interim periods ended March 31, 2005 and 2004
and cumulative from inception (August 5, 1988) to March 31, 2005.

The results of operations for the interim periods are not necessarily indicative
of the results of operations to be expected for the fiscal year. These interim
financial statements should be read in conjunction with the audited financial
statements and notes thereto for the year ended December 31, 2004, which are
contained in the Company's Annual Report on Form 10-KSB for the year ended
December 31, 2004 as filed with the Securities and Exchange Commission.

Note 3: Research and Development Costs

Research and development costs include the costs of materials, personnel,
outside services and applicable indirect costs incurred in development of the
Company's proprietary drug delivery system. All such costs are charged to
expense when incurred.

Note 4: Stockholders' Equity

During the three months ended March 31, 2005, the Company received net proceeds
of $32,377 ($1.022 per share) upon the exercise of 6,336 of the Representative
Unit Purchase Warrants that were issued to underwriters as part of the 2003
public offering. This resulted in the issuance of 31,680 shares of common stock
together with a similar amount of Representative's Common Stock Warrants. In
addition, 146,680 Representative's Common Stock Warrants were exercised ($1.28
per share) with a similar amount of common stock being issued and receipt of net
proceeds of $188,751.

The Company received a net amount of $68,100 upon the exercise of 90,000 in
stock options during the quarter. 60,000 options were exercised at a price of
$0.71 per share and 30,000 were exercised at a price of $0.85 per share.


                                       6.

Note 5: 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.

Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for
Stock-Based Compensation" 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 (loss) and pro
forma earnings (loss) per share disclosures for employee stock option grants 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 required by SFAS No. 123.


                                       7.






Following the methodology of SFAS No. 123 regarding compensation costs based on
the fair value for all employee stock option grants, the net loss and net loss
per share for the three months ended March 31, 2005 and 2004 would have been
increased to the pro forma amounts indicated as follows:

  Pro forma                              (0.06)                 (0.07)

In December 2004, the FASB issued SFAS No. 123 (Revised 2004), "Share-based
Payment" that will require the Company to expense costs related to share-based
payment transaction with employees. With limited exceptions, SFAS No. 123(R)
requires that the fair value of share-based payments to employees be expensed
over the period service is received and eliminates the ability to account for
these instruments under the intrinsic value method prescribed by APB No. 25, and
allowed under the original provisions of SFAS No. 123. SFAS No. 123(R) becomes
mandatorily effective for the Company on January 1, 2006. SFAS No. 123(R) allows
for either prospective recognition of compensation expense or retrospective
recognition, which may be back to the original issuance of SFAS No. 123 or only
to interim periods in the year of adoption. The Company is currently evaluating
these transition methods.

SFAS No. 123(R) allows the use of both closed form models (e.g., Black-Scholes
Model) and open form models (e.g., lattice models) to measure the fair value of
the share-based payment as long as that model is capable of incorporating all of
the substantive characteristics unique to share-based awards. In accordance with
the transition provisions of SFAS No. 123(R), the expense attributable to an
award will be measured in accordance with the Company's measurement model at
that award's date of grant.

Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

     (a) Plan of Operation

                           FORWARD LOOKING STATEMENTS

This report contains forward-looking statements which are subject to certain
risks and uncertainties that can cause actual results to differ materially from
those described. Factors that may cause such differences include, but are not
limited to, uncertainties relating to our ability to successfully complete Phase
III clinical trials and secure regulatory approval of our current or future
drug-delivery system and uncertainties regarding our ability to obtain financial
and other resources for any research, development and commercialization
activities. These factors, and others, are discussed from time to time in our
filings with the Securities and Exchange Commission. You should not place undue
reliance on these forward-looking statements, which speak only as of the date
they are made. We undertake no obligation to publicly update or revise these
forward-looking statements to reflect events or circumstances after the date
they are made.

                                    OVERVIEW

Since our founding in 1988 by a team of physicians, 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 for the development of our medical device and the clinical trials of
our product, and the pursuit of patents worldwide. We expect to continue to
incur significant losses from costs for product development, clinical studies,
securing patents, regulatory activities, manufacturing and establishment of a
sales and marketing organization without any significant revenues. A detailed
description of the cash used to fund historical operations is in the financial
statements and the notes thereto. Without an FDA-approved product and commercial
sales, we will continue to be dependent upon existing cash and the sale of
equity or debt to fund future activities. While 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.

During 2001, Delcath initiated the clinical trial of the system for isolated
liver perfusion using the chemotherapeutic agent, melphalan. The Phase I trial
at the National Cancer Institute marked an expansion in the potential labeled
usage beyond doxorubicin, the chemotherapeutic agent used in our initial
clinical trials. Enrollment of new patients in the Phase I trial was completed
in 2003 and following the 2004 presentation and adoption of a Phase II clinical
trial protocol, patients are being enrolled and treated.

During 2004, we commenced a Phase III clinical trial in Australia to proceed
with study of the Delcath drug delivery system for inoperable cancer in the
liver using doxorubicin. We are currently in discussions with additional sites
worldwide to expand this trial.

Over the next 12 months, we expect to continue to incur substantial expenses
related to the research and development of our technology, including Phase III
clinical trials using doxorubicin with the Delcath system and Phase II clinical
trials using melphalan with the Delcath system. Additional funds, when
available, will be committed to pre-clinical and clinical trials for the use of
other chemotherapy agents with the Delcath system for the treatment of liver
cancer, and the development of additional products and components. We will also
continue efforts to qualify additional sources of the key components of our
device, in an effort to further reduce manufacturing costs and minimize
dependency on a single source of supply.


                                       9.






Liquidity and Capital Resources

Our available funds will be sufficient to meet our anticipated needs for working
capital and capital expenditures at least through the end of 2006. The Company
is not projecting any capital expenditures that will significantly affect the
Company's liquidity during the next 12 months. The Company is projecting the
hiring of one additional employee.

Our future liquidity and capital requirements will depend on numerous factors,
including the progress of our research and product development programs,
including clinical studies; the timing and costs of making various United States
and foreign regulatory filings, obtaining approvals and complying with
regulations; the timing and effectiveness of product commercialization
activities, including marketing arrangements overseas; the timing and costs
involved in preparing, filing, prosecuting, defending and enforcing intellectual
property rights; and the effect of competing technological and market
developments.

The Company's future results are subject to substantial risks and uncertainties.
The Company has operated at a loss for its entire history and there can be no
assurance of its ever achieving consistent profitability. The Company believes
its capital resources are adequate to fund operations for at least the next
twelve months but anticipates that it will require additional working capital
after 2006. There can be no assurance that such working capital will be
available on acceptable terms, if at all.

During the three months ended March 31, 2005, the Company had exercises of
previously issued warrants together with exercises of stock options. Please see
Note 4 to the March 31, 2005 Condensed Financial Statements included in Part I
of this filing and incorporated herein by reference for a complete description
of share issuances together with receipt of proceeds. We plan to use the net
proceeds to fund, in part, the Phase III clinical trial using doxorubicin and
the Phase II clinical trial at NCI using melphalan.



                                       10.






Application of Critical Accounting Policies

The Company's financial statements have been prepared in accordance with
accounting principles generally accepted in the United States of America.
Certain accounting policies have a significant impact on amounts reported in the
financial statements. A summary of those significant accounting policies can be
found in Note 1 to the Company's financial statements contained in the Company's
Annual Report on Form 10-KSB for the year ended December 31, 2004 as filed with
the Securities and Exchange Commission. The Company has not adopted any
significant new accounting policies or modified the application of existing
policies during the three months ended March 31, 2005.

     (c)  Off-balance sheet arrangements

          The Company does not have any off-balance sheet arrangements.

Item 3. CONTROLS AND PROCEDURES

Based on an evaluation of the Company's disclosure controls and procedures
performed by the Company's Chief Executive Officer and its Chief Financial
Officer as of the end of the period covered by this report, the Company's Chief
Executive Officer and its Chief Financial Officer concluded that the Company's
disclosure controls and procedures have been effective.

As used herein, "disclosure controls and procedures" means controls and other
procedures of the Company that are designed to ensure that information required
to be disclosed by the Company in the reports that it files or submits under the
Securities Exchange Act is recorded, processed, summarized and reported within
the time periods specified in the rules and forms issued by the Securities and
Exchange Commission. Disclosure controls and procedures include, without
limitation, controls and procedures designed to ensure that information required
to be disclosed by the Company in the reports that it files or submits under the
Securities Exchange Act is accumulated and communicated to the Company's
management, including its principal executive officer or officers and its
principal financial officer or officers, or persons performing similar
functions, as appropriate to allow timely decisions regarding required
disclosure.

Since the date of the evaluation described above, there were no significant
changes in the Company's internal controls or in other factors that could
significantly affect these controls, and there were no corrective actions with
regard to significant deficiencies and material weaknesses.
