                     IMMUNOMEDICS ACQUIRES BECKMAN COULTER'S
                          SHARE OF IBC PHARMACEUTICALS

Morris  Plains,  NJ, May 24,  2002 --  Immunomedics,  Inc.  (Nasdaq:IMMU)  today
announced that Beckman  Coulter,  Inc. sold its membership  interest in a cancer
therapeutic joint venture, IBC Pharmaceuticals,  LLC, to Immunomedics. In return
for its 43% interest in the joint  venture,  Beckman  Coulter  received  138,900
shares of  Immunomedics  common  stock and a  five-year  warrant to  purchase an
additional  150,000  shares of  Immunomedics  common stock at a price of $65 per
share,   subject  to  adjustment  in  the  event  of  a  change  of  control  of
Immunomedics.  Immunomedics has agreed to promptly  register with the Securities
and Exchange  Commission all such shares for resale to the public. This transfer
of Beckman  Coulter's  ownership of the joint venture gives  Immunomedics  a 92%
ownership share, with other existing investors retaining an 8% ownership.

Immunomedics'  President  and Chief  Executive  Officer,  Cynthia  L.  Sullivan,
commented:  "IBC  Pharmaceuticals  focuses on the  development  of novel  cancer
therapeutics using proprietary pre-targeting,  bi-specific antibody technologies
developed  some years ago at  Immunotech in Marseille,  France.  Immunotech  was
later  purchased  by Coulter  Corporation,  which  subsequently  became  part of
Beckman Coulter.  IBC's first product  candidate is currently being evaluated in
Phase  I/II  clinical  trials  in France  for the  therapy  of tumors  producing
carcinoembryonic antigen, or CEA."

"IBC  Pharmaceuticals  and  Immunomedics   scientists  have  been  reengineering
bi-specific,  fused  antibodies  against CEA and a second  carrier  peptide that
delivers  therapeutic  doses of  radiation  to cancer  cells at ratios to normal
tissues that appear to exceed those of directly-radiolabeled  antibodies.  Since
we are a leader in the use of  radiolabeled  antibodies for cancer  therapy,  we
were  delighted  to be able to increase our  ownership in the joint  venture and
believe this will help us accelerate the  development of this  technology,"  Ms.
Sullivan remarked.

IBC Pharmaceuticals  currently has a 5-person  management board,  chaired by Dr.
David M. Goldenberg,  who is also the Chairman and Chief  Scientific  Officer of
Immunomedics,  Inc. Dr. Goldenberg stated: "I am grateful to Beckman Coulter for
the assistance and advice  provided  during the formative years of this venture,
which is now entering a second stage of development. I am also pleased that they
have decided to become shareholders of Immunomedics."

Immunomedics  is  a  biopharmaceutical   company  focused  on  the  development,
manufacture and commercialization of diagnostic imaging and therapeutic products
for the detection and treatment of cancer and infectious  diseases.  Integral to
these products are highly specific monoclonal  antibodies and antibody fragments
designed  to deliver  radioisotopes  and  chemotherapeutic  agents to tumors and
sites of  infection.  Immunomedics  has five  therapeutic  products  in clinical
trials and has two  marketed  diagnostic  imaging  products.  The most  advanced
therapeutic  product  candidates are LymphoCide(TM)  (epratuzumab),  which is in
Phase II and  Phase III  clinical  trials  for the  treatment  of  non-Hodgkin's
lymphoma, and CEA-Cide(TM) (labetuzumab), which is in Phase I/II clinical trials
for the treatment of certain solid tumors.

This release, in addition to historical  information,  contains  forward-looking
statements  made  pursuant to the Private  Securities  Litigation  Reform Act of
1995. Such statements,  including statements regarding clinical trials,  involve
significant  risks and  uncertainties and actual results could differ materially
from  those  expressed  or  implied  herein.   Factors  that  could  cause  such

development     (including    clinical    trials    outcome    and    regulatory
requirements/actions),  competitive  risks to marketed products and availability
of financing and other sources of capital, as well as the risks discussed in the
Company's Quarterly Report on Form 10-Q for the quarter ended March 31, 2002.
