IRS Issues Favorable Ruling Regarding Combination Of Outstanding “MIPS, MIPSB” Common Stock

MIPS Technologies, Inc., a leading provider of industry standard processor architectures and cores for digital consumer and business applications, announced today that the Internal Revenue Service has issued a favorable private letter ruling to Silicon Graphics, Inc. ("SGI") stating that MIPS Technologies' proposed reclassification of its Class A common stock and Class B common stock as a single class of common stock would not affect the qualification of SGI's June 2000 distribution of MIPS Technologies' Class B common stock to its shareholders as a tax-free distribution. The receipt of the IRS letter ruling removes one of the conditions that MIPS Technologies had established for its proceeding to recombine the two classes of its common stock.

Recombination of the two classes of MIPS Technologies' common stock requires stockholder approval on a class-by-class basis, which is being sought at MIPS Technologies' annual stockholder meeting to be held on November 12, 2003. Information on the proposal is provided in MIPS Technologies' Definitive Proxy Statement dated September 29, 2003, which is on file with the Securities and Exchange Commission, and a copy of which can be viewed on the company's website at www.mips.com/content/Corporate/InvestorRelations/FiscalYear2003Documents. If the requisite stockholder approval is obtained, MIPS Technologies intends to complete the reclassification of its common stock promptly after the meeting.
