News Release

INDIANAPOLIS, April 13, 2005 /PRNewswire-FirstCall via COMTEX/ -- Eli Lilly and Company (NYSE: LLY) announced today that the U.S. District Court for the Southern District of Indiana has stated that Judge Richard Young will render his decision on Thursday, April 14, 2005 at 5:50 p.m. Eastern Daylight Savings Time (which is 4:50 p.m. local Indianapolis time) in the Zyprexa(R) patent case of Eli Lilly and Company v. Zenith Goldline Pharmaceuticals et al.

Lilly remains confident Zyprexa's compound patent is valid and the generic manufacturers' claims are without merit. Although the company cannot predict the outcome or make guarantees of success in this litigation, Lilly continues to expect to prevail.

Lilly, a leading innovation-driven corporation, is developing a growing portfolio of first-in-class and best-in-class pharmaceutical products by applying the latest research from its own worldwide laboratories and from collaborations with eminent scientific organizations. Headquartered in Indianapolis, Ind., Lilly provides answers - through medicines and information - for some of the world's most urgent medical needs. Additional information about Lilly is available at www.lilly.com. C-LLY

This release contains forward-looking statements reflecting management's beliefs regarding the Zyprexa patent litigation. The company expects to prevail in this litigation. However, it is not possible to predict or determine the outcome of this litigation and, accordingly, the company can provide no assurance that it will prevail. An unfavorable outcome would have a material adverse impact on the company's consolidated results of operations, liquidity, and financial position.

Zyprexa(R) (olanzapine, Lilly)
