Amgen Comment On New OPPS Rule

THOUSAND OAKS, Calif., - Amgen Inc, October 31, 2002 - (Nasdaq:AMGN). The Centers for Medicare & Medicaid Services (CMS) today announced changes to the hospital outpatient prospective payment system. This announcement includes a rule that sets a reimbursement rate for Aranesp® (darbepoetin alfa) for Medicare patients in the hospital outpatient setting that will be significantly reduced effective January 1, 2003. The hospital outpatient setting accounts for approximately 10% of the current revenues of Aranesp. Reimbursement in the physician's office remains unchanged and continues to be set at 95% AWP.

CMS is directing the National Cancer Institute to initiate a clinical study to evaluate the appropriate dose conversion ratio for the rule. The rule further states that "if (CMS) can estimate a more accurate conversion ratio based on this study or from our review of our own payment data, we will make a change to reflect this ratio as soon as practicable."

In the rule, Aranesp and Procrit® are inaccurately characterized as "functionally equivalent" products and Aranesp is not recognized as a new therapy. Amgen objects to this mischaracterization of Aranesp. Aranesp is a unique and innovative biologic with a three times longer half-life and is dosed less frequently than is Procrit. The unique character of Aranesp is widely accepted and has been recognized by the FDA. Further, the new reimbursement rate set by CMS for the hospital outpatient setting was based on an Aranesp dose that is inconsistent with actual clinical practice.

Amgen will work vigorously to correct the inaccuracies in the rule in all appropriate forums.
