CORPORATE PROFILE

Altera Corporation, The Programmable Solutions Company(R), is a world leader in
one of the fastest growing segments of the semiconductor industry: high-density
programmable logic devices (PLDs). Altera PLDs are standard integrated circuits
that offer significant advantages over custom logic chips such as
application-specific integrated circuits (ASICs). Today's high-density PLDs,
used in concert with Altera's desktop software design tools and optimized
intellectual property building blocks, allow electronic systems manufacturers to
execute on a single chip the same functionality that previously consumed an
entire printed circuit board. This methodology, called "system on a programmable
chip" (SOPC), helps electronic systems manufacturers shorten time-to-market and
reduce development costs.

Altera serves over 13,000 customers in three primary market segments:
communications, electronic data processing, and industrial applications. The
Company sells its chips worldwide and derives nearly half of its revenues from
markets outside the United States. Altera common stock is traded on The Nasdaq
Stock Market(R) under the symbol ALTR. Altera's web site is located at
