To our customers,

Old Company Name in Catalogs and Other Documents

On April 1

, 2010, NEC Electronics Corporation merged with Renesas Technology

Corporation, and Renesas

Electronics Corporation

took over all the business of both

companies.

Therefore, although the old company name remains in this document, it is a valid

Renesas

Electronics document. We appreciate your understanding.
