          STMicroelectronics Added to the Philadelphia Stock Exchange
                        Semiconductor Sector Index (SOX)


Geneva, June 23, 2003 - STMicroelectronics (NYSE: STM) announced that it has
been added to the Philadelphia Stock Exchange Semiconductor Sector Index (SOX)
effective today. The SOX is a widely followed, price-weighted index comprised of
18 companies that are primarily involved in the design, distribution,
manufacturing, and sale of semiconductors. Based on its closing stock price on
June 20th, ST should be firmly within the top 50th percentile of the SOX.

Lynn Morgen, Group Vice President - Corporate Development at ST, commented, "We
are very pleased to have been selected for inclusion in this prestigious index.
We believe this reflects ST's performance track record and the global nature of
the semiconductor industry."

In addition to the SOX, ST belongs to a number of high-profile stock indexes.
Among these: the CAC-40, a modified capitalization-weighted index of 40
companies listed on the Paris Bourse; the MIB 30, a capitalization-weighted
index of 30 top Italian companies traded on the Milan Stock Exchange; the NYSE
Composite Index, a market-capitalization-weighted index of the 2045 stocks
traded on the New York Stock Exchange; the NYSE TMT Index; the NYSE
International 100 Index; the NYSE World Leaders Index; the Dow Jones Euro STOXX
Technology Index; the AMEX Semiconductor Index; and numerous other technology
indexes administered by international investment banks.

Also effective today, ST has been added to the Dow Jones Technology Titans 30
Index, which is designed to capture the performance of the most important and
influential technology companies. Additionally, ST has recently been honored by
its inclusion in the Financial Times top 500 global companies and as one of only
three semiconductor companies in BusinessWeek's InfoTech 100.
