ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

On March 29, 2007,  Delcath  Systems,  Inc. (the  "Company")  announced  that it
entered into a five-year  extension of its Cooperative  Research and Development
Agreement  (the  "CRADA")  with the National  Cancer  Institute  ("NCI"),  which
enhances  and  expands the  initial  agreement  between the Company and NCI that
expired in December 2006.  Under the revised  CRADA,  the Company and NCI agreed
that the parties will collaborate in the joint development and evaluation of the
Delcath System device to deliver high-dose Melphalan to patients and to evaluate
the  advisability of developing  additional  commercial  agents for use with the
Delcath   System,   the  Company's   percutaneous   perfusion   technology   for
region-specific delivery of chemotherapeutic and other therapeutic agents.

The revised CRADA also  established  that NCI's Surgery Branch will work towards
completion  of Delcath  System's  ongoing  Phase III trial and will serve as the
coordinating  center when this study expands to a multi-center  trial. The Phase
III trial is treating patients with melanoma (ocular or cutaneous) metastatic to
the liver using the Delcath System and the drug Melphalan.
