                  AMENDMENT NO. 1 TO DEVELOPMENT, PROMOTION,
                       DISTRIBUTION AND SUPPLY AGREEMENT

          AMENDMENT NO. 1 dated as of March 5, 2002 (this "Amendment"), by and

                            PRELIMINARY STATEMENTS

          A. ERS, BMS and the Company are parties to the Development,
Promotion, Distribution and Supply Agreement dated as of September 19, 2001
(the "Commercial Agreement") pursuant to which the Parties have agreed to
collaborate on the development and commercialization of Products in the
Territory.

          B. On October 30, 2001, pursuant to the Commercial Agreement, the
Company submitted a biologics license application for a Product under Section
351 of the Public Health Service Act. On December 28, 2001, the FDA notified
the Company that it would refuse to file such biologics license application
(the "Refusal to File").

          C. In light of the Refusal to File and subsequent discussions with
the FDA, the Parties have agreed to amend the Commercial Agreement as set
forth in this Amendment.

          NOW, THEREFORE, in consideration of the foregoing preliminary
statements and the mutual agreements and covenants set forth herein, the
Parties hereby agree as follows:

1.   DEFINITIONS.

          1.1 Definitions in the Commercial Agreement. Capitalized terms used
but not defined in this Amendment (including the Preliminary Statements set
forth above) shall have the meanings set forth in the Commercial Agreement.
References in the Commercial Agreement to "this Agreement" shall be deemed to
refer to the Commercial Agreement as amended by this Amendment.
Notwithstanding the foregoing, the date of the Commercial Agreement, as
amended hereby, shall in all instances remain September 19, 2001, and
references to "the date hereof", "the date of this Agreement" and "the
Effective Date" in the Commercial Agreement shall continue to refer to
September 19, 2001.

2.   MANAGEMENT.

          2.1 Clinical and Regulatory Oversight. The Parties agree that Andrew
Bodnar ("Bodnar") shall, for so long as he is willing to serve, be entitled to
oversee the implementation of the Clinical Development Plan and the process
for seeking Registration of Products pursuant to the Commercial Agreement.
Bodnar shall be entitled to attend meetings of any Committee, and any
Committee may from time to time consult with Bodnar with respect to any matter
relating to the Clinical Development Plan or Registration of the Product;
provided that Bodnar shall not have any powers, rights or responsibilities of
a member of a Committee (except to the extent he otherwise has such powers,
rights or responsibilities in his capacity as a member of such Committee), and
Bodnar's authority shall be subject to the authority of the Committees and the
other provisions of the Commercial Agreement. Bodnar shall also be entitled to

          indications relating to the same tumor type (e.g., colorectal

or such a "significant concern" under Section 13.3 of the Commercial
Agreement.

          7.2 Manufacturing Facility. As soon as reasonably practicable after
the date hereof, the Company shall resume construction of the BB-50 plant (the

           IMCLONE SYSTEMS AND BRISTOL-MYERS SQUIBB ANNOUNCE REVISED
             TERMS OF COMMERCIALIZATION AGREEMENT FOR ERBITUX(TM)


NEW YORK, NY - March 5, 2002 - Bristol-Myers Squibb Company (NYSE:BMY) and
ImClone Systems Incorporated (Nasdaq: IMCL) announced today the revision of
certain terms in the companies' commercialization agreement for the
co-development and co- promotion of ERBITUX(TM) in the United States, Canada
and Japan. The companies have agreed to changes in certain economics of the
agreement and have agreed to the expansion of the clinical and strategic role
of Bristol-Myers Squibb in the ERBITUX development program.

          Under the revised terms:

o         In lieu of the $300 million milestone payment agreed upon in the
          original agreement, Bristol-Myers Squibb will pay ImClone Systems
          $140 million in cash upon signing of the revised agreement and $60
          million in cash on the one-year anniversary of the signing.

o         Bristol-Myers Squibb will pay ImClone Systems the originally agreed
          upon $500 million milestone payment, based on the approval by the
          U.S. Food and Drug Administration (FDA) of ERBITUX, in two parts:
          $250 million will be paid upon approval of the initial indication,
          and the remaining $250 million will be paid upon approval of a
          second indication.

o         ImClone Systems will receive a distribution fee based on a flat rate
          of 39 percent of product revenues in North America.

o         The term of the agreement will continue to run through 2018.

          The companies said that Andrew G. Bodnar, M.D., J.D., senior vice
president of Medical and External Affairs, Bristol-Myers Squibb, and a member
of ImClone Systems' Board of Directors, will oversee a joint ImClone Systems
and Bristol-Myers Squibb team implementing a single clinical and regulatory
plan for ERBITUX. Governance of all

                                      12





committees provided for in the original agreement will remain unchanged.

          "ImClone Systems' objective is to move ERBITUX through the
regulatory process and to patients with cancer expeditiously," said Robert F.
Goldhammer, chairman of ImClone Systems. "The leadership and focus of ImClone
Systems' senior management and the firm commitment and support of its partner,
Bristol-Myers Squibb, strengthens our ability to achieve this goal."

          "We are confident that we will now be able to move forward in our
partnership with ImClone Systems for the development of ERBITUX," said Peter
R. Dolan, chairman and chief executive officer, Bristol-Myers Squibb. "As the
world leader in oncology, we are looking forward to playing an expanded
clinical and strategic role related to the ERBITUX development program,
working in close collaboration with the ImClone Systems team. The revised
agreement also reflects the adjusted timeline to market launch based on the
current development path for ERBITUX, which has been modified following the
February 26th meeting with the FDA."
