Altera Receives Additional NASDAQ Notice.

SAN JOSE, Calif. -- Altera Corporation (NASDAQ:ALTR) today announced that, as expected, it has received an additional NASDAQ Staff Determination notice indicating that the company is not in compliance with NASDAQ Marketplace Rule 4310(c)(14) because it has not timely filed its Quarterly Report on Form 10-Q for the period ended June 30, 2006. This notice is routinely issued to all NASDAQ-listed companies when required periodic filings have not been made with the SEC on a timely basis.

As previously announced, a NASDAQ Listing Qualifications Panel has granted Altera's request for continued listing of its securities on the NASDAQ Global Market, subject to certain conditions, including the following: (1) filing of the company's Form 10-Q for the period ended March 31, 2006, as well as any necessary restatements, on or before September 14, 2006; (2) filing of the company's Form 10-Q for the period ended June 30, 2006 on or before September 28, 2006; and (3) submission of additional information regarding the company's internal review of its historical stock option practices and related accounting. There can be no assurance that Altera will remain listed on NASDAQ unless and until the company can achieve full compliance with all requirements of the NASDAQ Global Market.
