CORNING, N.Y. -- Corning Incorporated (NYSE:GLW) and NetOptix Corporation

Corning common stock and each outstanding option to purchase NetOptix common
stock will become an option to purchase 0.90 shares of Corning common stock.

of common stock will be mailed on or about April 14, 2000 to each NetOptix
