A press release dated May 23, 2003 announcing that STMicroelectronics
repurchased a second portion of its Zero Coupon Senior Convertible Bonds due
2010.


STMicroelectronics Announces It Repurchased A Second Portion of Its Zero Coupon Senior Convertible Bonds due 2010 Geneva, May 23, 2003 - STMicroelectronics (NYSE: STM) reported that it has repurchased $214,000,000 of its Zero Coupon Senior Convertible Bonds due 2010, representing 9.97% of the total amount originally issued, for a total amount of $167,415,200. The Zero Coupon Senior Convertible Bonds were repurchased through a financial intermediary acting as agent for ST in off market transactions after the close of the Euronext Paris market on May 22, 2003 for an average price of $782.314 per Convertible Bond. The repurchased Bonds will be cancelled in accordance with the terms of the Indenture. This represents the second bond buy-back effected by the Company this year. To date, ST has repurchased 29.95% of the total amount originally issued of its Zero Coupon Convertible Bonds due 2010. As a result of the repurchase, ST will incur a one-time non-operating pre-tax charge of approximately $6.5 million in the second quarter of 2003. Based on market interest rates, however, the Company expects this transaction to result in savings of approximately $2.5 million in interest expense in the second half of 2003 and is expected to reduce ST's interest expense by approximately $5.0 million in 2004. Certain bondholders who sold Bonds held credit default swap positions as a hedge to those Bonds. The financial intermediary, acting as principal, effected transactions with some of those bondholders to unwind their credit default swap positions. ST's Zero Coupon Senior Convertible Bonds due 2010 are listed on Euronext Paris (Premier Marche).
