Gilead Sciences Calls for Redemption of Convertible Subordinated Notes

FOSTER CITY, Calif.--(BUSINESS WIRE)--Nov. 20, 2003--Gilead Sciences, Inc. (Nasdaq:GILD) has called for the full redemption on December 22, 2003 of its outstanding 5% Convertible Subordinated Notes due 2007 (the "Notes"). The aggregate principal amount outstanding of the Notes is $250,000,000. The CUSIP numbers for these notes are 375558AA1 and 375558AB9.

Prior to 5:00 p.m. Eastern Time, on December 19, 2003, holders may convert their Notes into shares of Gilead common stock at a price of $24.5625 per share, or 40.71 shares of Gilead common stock per $1,000 principal amount of the Notes. Cash will be paid in lieu of fractional shares. On November 19, 2003, the closing price of Gilead common stock on the Nasdaq National Market was $54.72 per share.

Alternatively, holders may have their Notes redeemed at a redemption price of $1,028.57 per $1,000 principal amount of Notes, plus accrued interest to the date of redemption. Any Notes not converted on or before 5:00 p.m. Eastern Time, on December 19, 2003, will be automatically redeemed on December 22, 2003, after which interest will cease to accrue. So long as the market price of the Gilead common stock is greater than $25.29 per share, a holder of the Notes who converts will receive Gilead common stock with a market value (together with cash in lieu of any fractional shares) greater than the amount of cash the holder would otherwise be entitled to receive upon redemption.
