For Immediate Release
GILEAD SCIENCES’ BOARD MEMBER ESTABLISHES
RULE 10B5-1 STOCK TRADING PLAN
Foster City, CA, May 3, 2004 – Gilead Sciences, Inc. (Nasdaq: GILD) today announced that it has implemented a stock trading program in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934. The policy permits participating Company executives and Board members to adopt pre-arranged stock trading plans to buy or sell pre-determined amounts of Company stock over time.
Rule 10b5-1 of the Securities Exchange Act of 1934 allows insiders to adopt written plans for trading securities in a non-discretionary, pre-scheduled manner in order to avoid concerns about initiating stock transactions when the insider may be aware of non-public information. Such plans also allow insiders to diversify their holdings and to minimize the market effect of stock sales by spreading them out over time.
Paul Berg, PhD, a member of Gilead’s Board of Directors, has established a stock trading plan under Rule 10b5-1. Under the plan, Dr. Berg may sell up to 86,000 shares over a period of approximately two years. The transactions under the plan will be disclosed publicly through Form 144 and Form 4 filings with the Securities and Exchange Commission. Other officers and directors of the Company may adopt Rule 10b5-1 plans in the future.
