SECTION 4 - MATTERS RELATED TO ACCOUNTANTS AND FINANCIAL STATEMENTS

ITEM 4.01   CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANTS.

      (a) On April 25, 2005, Eisner LLP ("Eisner") was dismissed as the
independent registered public accounting firm for Delcath Systems, Inc. (the
"Company"). The decision to change accountants was approved by the Audit
Committee of the Company's Board of Directors.

      The reports of Eisner on the balance sheets of the Company as of December
31, 2003 and 2004 and the related statements of operations, stockholders' equity
and cash flows for each of the years in the two-year period ended December 31,
2004 and for the period from August 5, 1988 (inception) to December 31, 2004 did
not contain any adverse opinion or disclaimer of opinion, nor were they modified
as to uncertainty, audit scope or accounting principles.

      In connection with the audits of the periods described above, and the
subsequent interim period through April 25, 2005, except for a reportable
condition with respect to the Company's internal controls regarding identifying
the Company's awards of stock options which awards were described in the
Company's Form 8-K reports dated March 22, 2005 and April 5, 2005, there were no
disagreements between the Company and Eisner on any matter of accounting
principles or practices, financial statement disclosure or auditing scope or
procedure, which disagreements, if not resolved to Eisner's satisfaction, would
have caused Eisner to make reference to the subject matter of the
disagreement(s) in connection with its reports.

      The Company has requested Eisner to furnish a letter addressed to the
Securities and Exchange Commission (the "Commission") stating whether it agrees
with the statements made by the Company in response to Item 304(a) of Regulation
S-K. The Company has requested that Eisner provide the letter as promptly as
possible so that the Company can file it with the Commission.

      (b) On April 27, 2005, the Company retained Carlin, Charron & Rosen, LLP
to act as its independent registered public accounting firm.
