                         INDEPENDENT AUDITORS' REPORT


The Board of Directors and Stockholders
Celgene Corporation:

     We have audited the consolidated financial statements of Celgene
Corporation and subsidiaries as listed in the accompanying index. In connection
with our audits of the consolidated financial statements, we also have audited
the consolidated financial statement schedule as listed on the accompanying
index. These consolidated financial statements and consolidated financial
statement schedule are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements and consolidated financial statement schedule based on our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Celgene
Corporation and subsidiaries as of December 31, 2002 and 2001, and the results
of their operations and their cash flows for each of the years in the
three-year period ended December 31, 2002, in conformity with accounting
principles generally accepted in the United States of America. Also, in our
opinion, the related consolidated financial statement schedule, when considered
in relation to the basic consolidated financial statements taken as a whole,
presents fairly, in all material respects, the information set forth therein.



     As discussed in Note 2(i) to the consolidated financial statements, the
Company adopted the provisions of Statement of Financial Accounting Standards
No. 141, "Business Combinations" effective July 1, 2001.
